`Method, network and control station for the two-wayalternate control of radio systems of
`different standards in the same frequency band
`
`x,hny
`
`10/089959
`
`_
`
`The inventionrelates to a methodofalternate control of radio systems of
`different standards in the same frequency band.
`
`

`

`
`A radio system for wireless transmission ofinformation is allowed to use
`transmission poweronly in accordance with standards. The national regulation authority
`determines on whatfrequencies with whattransmission power and in accordance with what
`radio interface standard a radio system is allowed to transmit. For this purposethere is
`provided for so-termed ISM frequency bands (Industrial Scientific Medical) that radio
`systems transmit in the same frequency band in accordance with different radio interface
`standards. An exampleofthis is the US radio system IEEE802.11a and the European ETSI
`BRAN HiperLAN/2. The tworadio systems transmit in the same frequency bands between
`5.5 GHz and 5.875 GHz with approximately the same radio transmission method, but
`different transmission protocols.
`In the eventof interference, method were standardized for an active switching
`. to another frequency within the permitted frequency band, for controlling transmission power
`and for the adaptive coding and modulation to reduce interference. Radio systems of
`wideband LANsoftheradio interface standards ETSI BRAN HiperLAN/2 and IEEE802.11a
`utilize the sameradio transmission method, a 64-carrier OFDM method and an adaptive
`modulation and coding. About the same modulation and coding methods (Link Adaptation,
`LA)are defined for the two standards.
`
`The Medium Access Control (MAC)ofthe two systemsis totally different.
`ETSI BRAN HiperLAN/2 utilizes a centrally controlled reservation-based method in which a
`radio station takes overtherole ofa central instance co-ordinating the radio resources. This
`central radio station (Access Point, AP) which may be an access point to the wide area
`network, periodically signals every 2 ms the MACframestructure from the AP and the
`associatedstations if required.
`The JEEE802.11a standard describes a CSMA/CA (Carrier Sense Multiple
`Access/Collision Avoidance) method not based on reservations, in whichall the radio

`stations listen in on the medium and assumethat the channelis unused for a minimum
`duration (Short InterFrame Space, SIFS) before 802.11a-MAC frames, thus user data
`packets, are transmitted if necessary. The methodis highly suitable for self-organizing ad hoc
`networks, but requires positive acknowledgementsofall the packets. Measures supporting
`service quality (Point Coordination Function PCF)in addition allow the support of
`multimedia applications. Fig. 2 shows by way of example the sequence for media access in
`accordance with IEEE802.11a. In accordance with a variant of the standard a stationis to
`then transmit an RTS packet (Ready To Send) and wait for a CTS packet (Clear To Send)
`from the addressedstation beforeit is allowed to transmit user data. All the otherstations in
`the radio coverage area set a time monitoring (Network Allocation Vector, NAV) and do not
`transmit until the addressed station has sent an acknowledgement (ACKnowledge, ACK).
`Wideband LANsin accordance with the HiperLAN/2 and 802.1 1a standards
`will operate in the same frequency bandin the future between 5.15 and 5.825 GHz. The
`wideband LANswork with Transmitter Power Control (TPC), it is true, with adaptive radio
`transmission methods and the Dynamic Frequency Selection (DFS)to minimize the
`alternating interfering effects, these methods, however, do not make optimum use and
`spreading possible of the radio channels overthe stations which transmit in accordance with
`different standards. The guarantee ofthe service quality necessary for the multimedia
`applications is impossible in the case ofinterference caused by their own stations or stations
`of outside systems. In caseofalternating interference, systems do not workefficiently and
`occupy a frequency channel even at low transmissionrates.
`
`10
`
`
`
`
`

`
`It is an object of the invention to provide a method, a wireless network and a
`control station which makeefficient use of radio transmission channels possible.
`This object is achieved for the method in accordance with the invention by an
`interface control protocol methodfor a radio system, which system comprisesat least a
`frequency band providedfor the alternate useofa first and a second radio interface standard,
`the radio system comprising stations which operate in accordancewithafirst radio interface
`Standard and/or a second radio interface standard, respectively, a control station being
`provided which controls the alternate use of the frequency band.
`The inventionis based on the idea of providing a comprehensive standard
`exchangeof implicit or explicit control information in systems that have the same radio
`transmission methods butdifferent radio transmission protocols. This makes a simple and
`efficient use possible of a radio channel via a plurality of radio interface standards.

`Theradio system comprises one or morestations. Thestations maybe, for
`example, computers of a wireless local area network. Thesestations may be arranged, for
`example, only for operation in accordancewith a first or second radio interface standard. But
`it is also possible for stations to operate in accordance with both thefirst and the secondradio
`interface standard.
`
`A first numberofstations preferably forms a wireless local area network in
`accordancewithafirst radio interface standard and a second numberofstations forms a
`wireless network in accordance with a secondradio interface standard. Thefirst radio
`interface standard may be, for example, the HiperLAN/2 standard andthe second radio
`interface standard may be the IEEE802.11a standard.
`For these two standards is reserved the frequency band from 5.15 GHz to
`
`10
`
`
`
`25
`
`30
`
`5.825 GHz.
`
`In accordance with the invention a control station is provided which controls
`the alternate use of the common frequency band ofthe two radio interface standards.
`The control station is preferably a station that may operate in accordance with
`both the first and the second radio interface standard.
`The control of the alternate use of the commonfrequency band may be
`effected in various ways. For example,it is possible to provide certain predefinable time
`intervals for the use ofthe first and secondradio interface standard andallocate the frequency
`bandalternately to the first radio interface standard and then to the secondradio interface
`standard in a kind of time-division multiplex mode.
`However,it is advantageousto effect the allocation by means of adaptive
`protocols. The commonradio channel can thenbe utilized more effectively particularly when
`the demand for transmission capacity in accordancewith the first and the secondradio
`interface standard varies.
`
`In the advantageous embodimentofthe invention as claimed in claim 2, the
`control station is provided, on the one hand,for controlling the access to the frequency band
`for stations operating in accordance with thefirst radio interface standard. If the first radio
`interface standard is, for example, the HiperLAN/2 standard, the controlstation performsthe
`function ofthe central controller (Access Point AP) in accordance with this standard. In that
`case the stations of the HiperLAN/2 standard send a request for capacity to the control station
`and the controlstation allocates transmission capacity to each respective station.
`Onthe other hand, the controlstation is provided in an advantageous
`embodimentof the invention as claimed in claim 2 for releasing the common frequency band
`

`for access by stations operating in accordance with the secondradio interface standard,if
`stations operating in accordance with thefirst radio interface standard do not request access
`to the frequency band. In this advantageous embodimentofthe invention thefirst radio
`interface standard is given priority over the secondradio interface standard in this manner.
`The release ofthe common frequency band for the secondradio interface standard may be
`effected, for example, explicitly by the sending of control information to the stations of the
`second radio interface standard.
`
`Alternatively, it is possible, for example, that the point coordinator provided in
`accordance with the IEEE802.11a standard operates as the central control station and controls
`the alternate accessofstationsofthe first and second radio interface standard to the common
`frequency band.In this advantageous embodimentofthe invention the point coordinator
`could for example periodically render the common frequency band available to another radio
`interface standard, for example, to the HiperLAN/2 standard.
`In the advantageous embodimentas claimed in claim 3, the control is effected
`in that the contro] station determines the respective duration in which thestations operating in
`accordance with the secondradiointerface standard can utilize the common frequency band.
`Determining the duration may advantageously be effected as claimed in claim 4 in that the
`control station sends a broadcast signal which informsthestationsof a time period in which
`the frequency band can be used bystations operating in accordance with the secondradio
`interface standard.
`
`It is an advantage ofthe invention that when radio systems are operated in
`phases in which no information is sent or received by a radio station in accordance with a
`first radio interface standard, the additional sending of information in accordance with
`another radio interface standard becomespossible, so that the access to the radio channel can
`be controlled by competing radio systems.
`
`
`
`25
`
`It is then possible for a first radio station operating in accordance withafirst
`radio interface standardto additionally carry out certain functions described in a second radio
`interface standard, while the first radio station or a coordinating further radio station that
`transmits in accordance withthefirst radio interface standard determines the beginning and
`duration of the phase that may be used by thefirst station for transmission in accordance with
`the second radio interface standard.
`
`30
`
`Dependingon theradio interface standard, beginning and duration can be
`defined only approximately, while the respective standards are violated regularly or from
`time to time. The first station may preferably end the phase during which it transmits in

`accordance with the second radiointerface standard, while disregarding resulting interference
`in stations operating in accordance with the second radio interface standard,
`Thefirst radio station may, in addition to functions in accordancewith the
`secondradio interface standard, also carry out functions that cause radio systems working in
`accordance with the second radio interface standard or radio systems working in accordance
`with the first radio interface standard to interpret the radio channel as interfered and occupy
`another radio channel for its own operation.
`The efficient commonuseof a radio channel by different radio systems may
`be achievedvia a suitable control protocol method. Sucha radio interface control protocol
`methodenablesa first station of a radio system working in accordance with the first radio
`interface standard to control the access times to the radio channel by otherstations. For this
`purpose this first station then has to carry out functions described in another, second radio
`interface standard in addition to the functions laid down by its own first radio interface
`standardat times at which stations working in accordance with the first radio interface
`standard do not send and do not expect information in accordance with the standard from the
`first station, while thefirst station or a further station determines the duration for which the
`first station is allowed to transmit in accordance with the second radio interface standard. The
`duration of the operation in accordance with the second radio interface standard need not be
`determined exactly but may also be determined approximately. A transmission in accordance
`with the first radio interface standard can provide thatthe first station terminates the use of
`the radio interface in accordance with the second radio interface standard without taking
`resulting interference into accountin stations that send in accordance with the second radio
`interface standard.
`
`The object of the invention is achieved for the network bya wireless network
`that hasat least one frequency band that is provided for the alternate use by a first and a
`second radio interface standard, while the wireless network comprises stations that work in
`accordance with the first and/or the secondradio interface standard, a control station being
`provided which controls the alternate use of the frequency band.
`
`Several examples of embodimentofthe invention will be further explained
`below with reference to the drawing in the Figs. 1 to 3, in which:

`Fig. 2 gives a diagrammatic representation of the access to a radio channelin

`
`Fig. 1 showsthestructure of the HiperLAN/2-MACframe.
`Fig. 2 diagrammatically shows the media access in systems working in
`accordance with the radio interface standard IEEE802.1 1a.
`
`In a HiperLAN/2 system the central controller can be controlled via the
`Access Point (AP) which periodically generates the MAC frame and then transmits the data
`ofthe broadcast phase to individually control the service quality (packet delay sendingrate
`and so on) of individuallinks.
`
`Transmission in Figs. 1 and 2 with respect to the associated standardsis
`understood to mean that a HiperLAN/2 APina partially unused downlink, uplink and direct-
`mode phase could dispense with sending useless (dummy) information and giving 802.11-
`systems no opportunity to observe an unused channel for a period of time SIFS and starting
`the run as shown in Fig. 2. The AP couldreadily regain the control in which the transmission
`in accordance with the HiperLan/2 standard does not suppress the broadcast phase, but
`transmission takes place. Likewise, the function PCF of the 802.11 standard could be used to
`occasionally renderthe radio channel available to HiperlAN/2 systems with a time limit
`(periodically).
`
`The alternate control of radio systemsof different standards, which controlis
`proposed here and discussed with respect to an example of the wideband LANs ETSI BRAN
`HiperLAN/2 and IEEE802.11a, may guarantee in a heterogeneous environment in which
`various radio systems simultaneously transmit very close together in the same spectrum, a
`decentrally controlled adaptivity relative to the transmission capacity available in the
`respective systems for the managementofthe respective current traffic supply, of the
`required service quality and ofthe environment of use. When the integrated controller in
`accordance with the invention is used, different radio systems may be made compatible in the
`way that they constructively coexist in the same frequency band and then can provide
`services that require a high service quality. The radio spectrum is clearly used more
`efficiently; without the implementation of the new methodthis is only possible with
`respective exclusively used radio channels.

`A first wireless local area network comprises three stations 10, 11 and 12.
`Thesethree stations 10, 11 and 12 work in accordance with the first radio interface standard
`A, for example, in accordance with the HiperLAN/2 standard.
`A second wireless local area network includesfour stations 14, 15, 16 and 17.
`These fourstations 14, 15, 16 and 17 work in accordance with the second radio interface
`standard B, for example, in accordance with the IEEE802.11a standard.
`The stations may be, for example, computers which include a radio interface.
`The communication between the individualstations is effected in a wireless fashion, for
`example, by radio.
`
`For wireless local area networks in accordance with the HiperLAN/2 and
`IEEE802.1 1a standardsthe frequency band is comprised between 5.15 GHz and 5.825 GHz.
`A central control station 13 is provided which controls the alternate access by
`the first wireless network and the second wireless network to the common frequency band.
`This may be effected in an advantageous mannerin that the station 13 sends a
`broadcast messageto thestations 14 to 17 of the IEEE802.11a standard when the stations 10
`to 12 do not need transmission capacity. This broadcast message preferably contains time
`information which informsthe stations 14 to 17 ofthe IEEE802.11 standard how long they
`are allowedto utilize the commonfrequency band. During this time the control station 13 can
`also carry out functions in accordance with the IEEE802.11a standard, for example, also be
`used for data transmission in accordance with theJIEEE802.11a standard.
`If the stations 10 to 12 ofthe first wireless network are HiperLAN/2 stations,
`the control station 13 preferably also operates as the central control station (Access Point) of
`the HiperLAN/2 network and co-ordinatesits radio resources. In HiperLAN/2 systemsit is
`planned beforehand at what timethe stations are allowed to send. Forthis purpose the
`HiperLAN/2 systems have a central controller (Access Point, AP) which receives the
`requests for capacity from the variousstations and assigns capacity accordingly. The central
`control station 13 is preferably also provided for carrying out the function ofthe access point
`ofthe HiperLLAN/2 standard. The central control station 13 then periodically signals every 2
`ms the MAC framestructure in accordance with the requirements ofthe individual stations of
`the HiperLAN/2 network.
`
`Alternatively, it is also possible, however, in HiperLAN/2 systemsfor the
`function ofthe access point and the function ofthe alternating control of the access to the
`commonfrequency bandbythe first wireless network and the second wireless network to be
`realized in separate stations. In that case, however, with respect to the duration in which the

`frequency band can beutilized by the first or second radio interface standard a data exchange
`
`is necessary between these separate stations.
`
`Alternatively, it is possible, for example, for the point co-ordinator provided in
`
`accordance with the IEEE802.11 standard to operate as a central control station and to
`
`5_control the alternate access to the common frequency band bystations of the first and second
`
`radio interface standards. In this embodiment the point co-ordinator would, for example,
`
`periodically render the common frequency band available to another radio interface standard,
`
`for example, to the HiperLAN/2 standard.
