`
`DESCRIPTION
`
`RADIO COMMUNICATION SYSTEM
`
`5
`
`The present invention relates to a method of operating a radio
`
`communication system, and further relates to such a system and to primary
`
`and secondary stations for use in such a system. While the present
`
`specification describes a system with particular reference to the emerging
`
`Universal Mobile Telecommunication System (UMTS), it is to be understood
`
`10
`
`that such techniques are equally applicable to use in other mobile radio
`
`systems.
`
`In a radio communication system it is generally required to be able to
`
`exchange signalling messages between a Mobile Station (MS) and a Base
`
`15
`
`Station (BS). Downlink signalling (from BS to MS) is usually realised by using a
`
`physical broadcast channel of the BS to address any MS in its coverage area.
`
`Since only one transmitter (the BS) uses this broadcast channel there is no
`
`access problem.
`
`In contrast, uplink signalling (from MS to BS) requires more detailed
`
`20
`
`considerations. If the MS already has an uplink channel assigned to it, for
`
`voice or data services, this signalling can be achieved by piggy-backing, in
`
`which the signalling messages are attached to data packets being sent from
`
`the MS to the BS. However, if there is no uplink channel assigned to the MS
`
`piggy-backing is not possible. In this case a fast uplink signalling mechanism
`should be available for the establishment, or re-establishment, of a new uplink
`
`25
`
`channel.
`
`In conventional systems, for example those operating to the Global
`
`System for Mobile communication (GSM) standard, fast uplink signalling is
`
`enabled by the provision of a random access channel using a slotted ALOHA
`
`30
`
`or similar protocol. However, such a scheme works satisfactorily only with a
`
`low traffic load, and is not believed to be capable of handling the requirements
`imposed by third-generation telecommunications standards such as UMTS.

`
`PHB 34306 US
`
`To meet these requirements one UMTS embodiment includes a
`
`dedicated signalling channel, which comprises frames including a time slot for
`
`each MS registered with the controlling BS. If a MS requires a service from the
`
`5
`
`BS
`
`it
`
`transmits a
`
`request
`
`in
`
`its allocated slot
`
`then waits
`
`for an
`
`acknowledgement from the BS setting up the required service. Parameters
`
`which characterise the performance of the signalling channel include the false
`
`alarm rate (where the BS erroneously identifies a MS as requesting a service),
`
`the missed detection rate (where the BS does not detect a request from a MS),
`
`10
`
`and the delay between a request for a service by the MS and the provision of
`
`that service by the BS.
`
`An object of the present invention is to improve the efficiency of the
`
`method by which a MS requests resources from a BS.
`
`15
`
`According to a first aspect of the present invention there is provided a
`
`method of operating a radio communication system, comprising a secondary
`
`station transmitting a request for resources to a primary station in a time slot
`
`allocated to the secondary station, characterised by the secondary station re(cid:173)
`
`transmitting the request in at least a majority of its allocated time slots until an
`
`20
`
`acknowledgement is received from the primary station.
`
`This scheme improves the typical time for a response by the primary
`
`station to a request by a secondary station. Because there is no possibility of
`
`requests from different secondary stations ·colliding, a secondary station can
`
`retransmit requests in each allocated time slot. In contrast, in prior art systems
`
`25
`
`a secondary station has to wait at least long enough for the primary station to
`
`have received, processed and acknowledged a request before it is able to
`
`retransmit.
`Further, the primary station can improve the accuracy with which it
`
`determines whether a request was sent by a particular secondary station if the
`
`30
`
`received signal strength is close to the detection threshold by examining the
`
`received signals in multiple time slots allocated to the secondary station in
`question.

`
`PHB 34306 US
`
`According to a second aspect of the present invention there is provided
`
`a radio communication system comprising a primary station and a plurality of
`
`secondary stations, the primary station having means for allocating a time slot
`
`for a secondary station to transmit a request for resources to the primary
`
`s
`
`station, characterised in that the secondary station has means for re(cid:173)
`
`transmitting the request in at least a majority of its allocated time slots until it
`
`receives an acknowledgement from the primary station.
`
`According to a third aspect of the present invention there is provided a
`
`primary station for use in a radio communication system, the primary station
`
`10
`
`having means for allocating time slots to secondary stations for requesting
`
`resources, characterised in that the primary station has combining means for
`
`determining from a combination of received signals in a plurality of successive
`
`time slots allocated to the secondary station whether the secondary station
`
`has transmitted a request for resources.
`
`15
`
`According to a fourth aspect of the present invention there is provided a
`
`secondary station for use in a radio communication system including a primary
`
`station having means for allocating a time slot for the secondary station to
`
`transmit a request for resources to the primary station, characterised in that
`
`means are provided for re-transmitting the request in at least a majority of the
`
`20
`
`allocated time slots until an acknowledgement is received from the primary
`
`station.
`
`The present invention is based upon the recognition, not present in the
`
`prior art, that in a system having time slots allocated to a secondary station for
`
`requesting
`
`resources,
`
`improved performance can be obtained by
`
`the
`
`25
`
`secondary station repeating the request until an acknowledgement is received.

`Embodiments of the present invention will now be described, by way of
`
`example, with reference to the accompanying drawings, wherein:

`
`15
`
`Referring to Figure 1, a radio communication system comprises a ·
`
`primary station (BS) 100 and a plurality of secondary stations (MS) 110. The
`
`BS 100 comprises a microcontroller (µC) 102, transceiver means 104
`
`connected to radio transmission means 106, and connection means 108 for
`
`20
`
`connection to the PSTN or other suitable network. Each MS 110 comprises a
`
`microcontroller (µC) 112,
`
`transceiver means 114 connected
`
`to
`
`radio
`
`transmission means 116, and power control means 118 for altering the
`
`transmitted power level. Communication from BS 100 to MS 11 0 takes place
`
`on a downlink channel 122, while communication from MS 110 to BS 100
`
`25
`
`takes place on an uplink channel 124.
`The present invention
`is concerned with an uplink channel 124
`
`dedicated to the transmission of requests for services by a MS 110 to a BS
`
`100. One arrangement of such a channel for UMTS is illustrated in Figure 2.
`
`The uplink channel 124 is divided into a succession of frames 202, each of
`
`30
`
`length 1 Oms, and each MS 110 registered with the BS 100 is allocated a time
`
`slot 204 in each frame in which it can transmit a request for service. Although
`
`ERICSSON v. UNILOC
`Ex. 1002 / Page 6 of 266
`
`

`

`•.
`
`5
`
`PHB 34306 US
`
`only ten time slots 204 are shown in each frame 202, in practice there may be
`
`many more per frame.
`
`Although it is anticipated that a single dedicated uplink channel 124 will
`
`provide sufficient capacity in normal situations, it is possible for there to be
`s more mobile stations 110 registered with a BS 100 than there are available
`time slots in each frame. In such circumstances the BS 100 can either make
`
`another uplink channel 124 available for fast signalling purposes or increase
`
`the capacity of the existing channel by not allocating a time slot for every MS
`
`110 in every frame.
`
`10
`
`In traditional signalling schemes, for example that used for the random
`
`access channel in GSM, a MS 110 makes a request for service to a BS 100
`
`and
`
`then waits
`
`for an acknowledgement
`
`from
`
`the BS 100.
`
`If no
`
`acknowledgement is received after a predetermined period of time, the MS
`
`110 assumes that the request was not correctly received and schedules
`
`15
`
`another request. This scheme minimises traffic on the channel to minimise
`
`collisions between requests from different mobile stations 110 thereby avoiding
`
`loss of channel capacity.
`
`However, in a dedicated uplink channel 124 having time slots allocated
`
`to each MS 110 collisions will not normally occur. A more effective signalling
`
`20
`
`scheme, in accordance with the present invention, is that shown in Figure 3.
`
`The process starts at 302 when the MS 110 determines that it requires a
`
`service from the BS 100. The MS 110 then makes a request for service 304 in
`
`the next time slot 204 (Figure 2) allocated· to it. In a Code Division Multiple
`
`Access (CDMA) system,
`
`the request 304
`
`is made by transmitting a
`
`25
`
`predetermined code sequence. Requests 304 continue to be made in
`
`successive allocated time slots 204 until a first test 306 determines that no
`
`further requests should be made, for example by examining the value of a flag
`
`that was set to true at the start 302 of the process.
`
`A second test 308 determines whether the MS 110 has received an
`
`30
`
`acknowledgement from the BS 100. When the second test 308 determines
`
`that an acknowledgement has been received from the BS 100, the MS 110 at
`
`310 stops any further requests from being sent, for example by setting to false
`
`ERICSSON v. UNILOC
`Ex. 1002 / Page 7 of 266
`
`

`

`·-
`
`6
`
`PHB 34306 US
`
`a flag that is checked by the first test 306. The MS 110 then begins
`
`negotiations 312 with the BS 100 to define fully the required services. Finally,
`
`at 314, the required services are set up by the BS 100.
`
`This scheme has the advantage that if a request is not received
`
`5
`
`correctly by the BS 100 it can be repeated at the frame rate ( 100 Hz for the
`
`1 Oms frame defined in UMTS), or at least in every allocated time slot if the
`
`system is busy and a time slot is not allocated in every frame. In a traditional
`
`scheme it is not guaranteed that a request could be received and processed
`
`by the BS 100 sufficiently rapidly for an acknowledgement to be scheduled for
`
`10
`
`the immediately following frame, so the time that a MS 110 has to wait before
`
`re-transmitting the request is substantially longer.
`
`A further advantage of the signalling scheme in accordance with the
`
`present invention is that the quality of detection at the BS 100 can be improved
`
`by combining requests. Since the BS 100 knows that requests will be repeated
`
`15
`
`in every frame, it can postpone making a decision about a possible received
`
`request when this request is near to the decision threshold and use
`
`information from the next (and subsequent) frames to improve the confidence
`
`of the decision. This amounts to a form of time diversity, and will improve the
`
`robustness of the signalling scheme to the effects of fading, near-far effect and
`
`20
`
`other interference.
`
`In one embodiment of UMTS, the dedicated uplink channel employs a
`CDMA technique. Using information transmitted on a downlink broadcast
`channel 122 by the BS 100, each MS 110 is able to determine the uplink
`
`signalling sequence it should use (thereby defining the dedicated uplink
`
`25
`
`channel 124) and the time slot 204 it is allocated in a frame 202. The uplink
`
`signalling sequence is detected at the BS 100 by a matched filter, and the time
`
`at which a peak appears in the output of the matched filter indicates which MS
`
`110 issued the request.
`
`Simulations have been performed to investigate the advantages of
`
`30
`
`combining successive transmitted requests at the BS 100. Figure 4 is a
`complex phasor plot illustrating a model for the effect of noise on the output of
`
`the matched filter in the BS 100. Noise was modelled as complex Gaussian
`
`ERICSSON v. UNILOC
`Ex. 1002 / Page 8 of 266
`
`

`

`...
`
`7
`
`PHB 34306 US
`
`noise, with the result that the output 402 of the matched filter is the vector sum
`
`of a signal peak 404 and a complex Gaussian noise vector 406. In the
`
`absence of a signal 402, the filter output is simply complex Gaussian noise.
`
`In a first simulation the level of the signal 404 was held fixed and
`
`s
`
`varying levels of noise 406 applied. In a scheme with no combining the
`
`magnitude of the filter output vector 402 is compared to a threshold value, and
`
`if it exceeds this value a signal is assumed to be present. Two different error
`
`rates were measured: the False Alarm Rate (FAR), which is the probability of
`
`detecting a signal when only noise is present; and the Missed Detection Rate
`
`10
`
`(MOR), which is the probability of failing to detect a signal which is present.
`
`A simple combining scheme was also simulated,
`
`in which
`
`the
`
`magnitudes of two successive matched filter outputs were added together and
`
`compared to a (different) threshold to determine whether a signal was present.
`
`For both schemes the threshold was set as a multiple of the rms noise
`15 magnitude such that the FAR remained constant at 1 %.
`The results are shown in Figure 5, which is a plot of the MOR in percent
`
`against the ratio of the signal magnitude to mean noise magnitude (SNR) in
`
`dB. The solid curve shows the results for the scheme without combining and
`
`the dashed curve the results with combining. The results of the combining
`
`20
`
`scheme show a significant
`
`improvement
`
`in MOR, equivalent
`
`to an
`
`improvement of typically 2dB in SNR.
`
`In a second simulation the level of the signal 404 was subjected to
`
`Rayleigh fading, to provide a more realistic mobile environment. The results
`
`are shown in Figure 6, which is a plot of the MOR in percent against the SNR
`
`25
`
`in dB. The solid curve shows the results for the scheme without combining and
`
`the dashed curve the results with combining. In both cases the results show
`
`significantly higher MOR for a given signal to noise ratio than the simulation
`
`without fading, as might be expected. Again the results of the combining
`
`scheme show a significant
`
`improvement
`
`in MOR, equivalent
`
`to an
`
`30
`
`improvement of between 2 and 5dB in SNR.
`
`Alternative combining schemes could be used
`
`in a method
`
`in
`
`accordance with
`
`the present
`
`invention. The
`
`results discussed above
`
`ERICSSON v. UNILOC
`Ex. 1002 / Page 9 of 266
`
`

`

`8
`
`PHB 34306 US
`
`demonstrate the improved accuracy resulting from combining two successive
`
`filter outputs. Further improvements could be obtained by combining more
`
`outputs, although at the cost of increased delay in the BS 100 responding to
`
`the requests from the MS 110.
`
`5
`
`A multiple threshold scheme could offer further advantages. Such a
`
`scheme would operate by examining the magnitude of the filter output. If it is
`
`above an upper threshold then a request has been detected which the BS 100
`
`can acknowledge immediately, while if it is below a lower threshold no request
`
`has been detected. If the output lies between the two thresholds then signal
`
`10
`
`combining schemes such as those described above can be used to resolve
`
`the question of whether a request was sent.
`
`Some form of power control is also desirable. If a MS 110 transmits a
`
`request at too high a power level it may swamp other signals at the BS 100,
`
`while if it transmits at too low a power level the request will not be detected.
`
`15
`
`Closed loop power control is not available until the requested services are set
`
`up. Open loop power control is possible if the MS 110 uses the characteristics
`
`of a broadcast channel from the BS 100 to determine the initial power at which
`
`to transmit its requests. If no acknowledgement is received from the BS 100
`
`the power at which the requests are transmitted could be gradually increased,
`
`20
`
`subject to appropriate maximum power limits.
`
`In a Rayleigh fading environment there could also be advantages in
`
`having random or other variations in the transmitted power level.
`
`A further application of a method· in accordance with the present
`
`invention is in the provision of paging or other services, where a BS 100
`
`25
`
`transmits messages on a downlink channel 122 to a MS 110, and continues
`
`retransmitting until an acknowledgement is received from the MS 110. In this
`
`application therefore the BS 100 functions as a secondary station and the MS
`110 as a primary station.
`
`From reading
`
`the present disclosure, other modifications will be
`
`30
`
`apparent to persons skilled in the art. Such modifications may involve other
`
`features which are already known in radio communication systems and

`ABSTRACT

`
`PHB 34306 US
`
`RADIO COMMUNICATION SYSTEM
`
`5
`
`A method of operating a radio communication system
`
`in which
`
`secondary stations use dedicated time slots to request services from a primary
`
`station. A secondary station wishing to request a service sends a request in
`
`every time slot allocated to it until it receives an acknowledgement from the
`
`primary station. The primary station can use combining techniques on multiple
`
`10
`
`time slots to identify the presence or absence of a request from a secondary
`
`station with improved accuracy.
