`communication system and a method thereof.

`communication device for improving interleave transmission
`and transmj-ssion power control
`in spread spectrum
`communj-cation, and
`for
`realizinq handovers between
`different frequencies and a method thereof.
`
`BACKGROUND ART
`ln a CDMA cellular system, because the same carrier
`frequency is used repeatedly in every ceII there is no need
`for handovers between frequencies within the same system.
`However, considering a case such as when existing systems
`are present together, there is a need for handovers between
`different carrier frequencies. Three points pertaining to
`{
`detailed cases are described below.

`
`consj-derable traffic, a separate carrier frequency is used
`to accommodate the increased number of subscribers, and a
`handover may be performed between those celIs. As a second
`point, when an umbrella cell consti-tution is used,
`frequencies are allocated to large and small
`different
`cells, and handovers are performed between the cells. Then,
`as a third poj-nt, there are cases of handovers between a
`third qeneration system, such as a W (Wideband) -CDMA system,
`and a second generati-on system, such as a current mobile
`telephone system.
`in cases such as
`When performing handovers

`carriers at the different
`detection, the receiver needs to only have a structure
`However, this
`capable of detecting two frequenci-es.
`increases the size of the constitution of the receiver, or
`makes the constitution complicated.
`Furthermore, two types of handover method may be
`considered: a mobile assisted handover (MAHO) and a network
`Comparing the -I4AHO and NAHO
`20 assisted handover (NAHO) .
`methods/ NAHO reduces the burden of the mobile devlce, but
`to be successful, it should be necessary to synchronize the
`mobile devj-ce and' the base station, whereby the
`constituti-on of the base station and the network becomed
`complicated and large in order to be capable of tracking
`
`25
`
`LGE_0000702
`
`

`

`each individual mobile device.
`For such reasons/ the realization of the MAHO method
`is more desirable, but to determine whether or not to
`handover, it
`is necessary to measure the strength of
`carriers of different
`frequencies at the mobile devices.
`However/ a CDMA celIular system differs
`from a ti-me
`division multiplex access (TDMA) system used in a second
`gieneration, in
`that
`it
`uses ordinariry
`continuous
`transmi-ssion for both transmission/reception.
`fn this
`continuous
`t ransmi s s ion/ reception
`unless
`techni-que,
`receivers corresponding to two frequencies are prepared, it
`is necessary to stop the timing of the transmission or the
`reception and measure the other frequency.
`There has been disclosed a technique relating
`to a
`compressed mode method,
`for
`time-compressing the
`transmission data in the usual mode and transmitting it
`in
`a short time, thereby creating some spare time which can be
`utilized
`to measure the other frequency carrier
`As an
`example of this, there is Japan Patent Application Natlonal
`Publication (Laid-Open) (JP-A) No. 8-500475 "Non-continuous
`Transmission for Seamless Handovers j-n DS-CDMA Systems".
`This application discloses
`method of
`reali- z:ng a
`compressed mode, wherein the spreading factor of
`the
`spreading code used is lowered to
`compress the transmission

`

`The method of realizLnq the compressed mode according
`to the above application will be explained below. FIG. 36
`shows an example of transmissions in a normal mode and a
`compr€ssed mode in a conventional CDMA system. In FIG. 36,
`the vertical axis represents transmission rate/transmission
`In the
`power, and the horizontal axis represents time.
`example of EIG. 36, the compressed mode transmission is
`inserted between normal transmission frames.
`In the transmission in the compressed mode, a non-
`transmission timing is provided in the downlink frame, and
`can be set to a desired period of time (duration) . This
`non-transmlssion timing represents idle period during which
`the strength of the other frequency carrier is measured.
`transmi-ssion can be achieved by
`this wdy, ,fott"a
`In
`inserting the idle period during transmission of compressed
`mode frames
`type of compressed mode transmission,
`this
`In
`transmission power increases in accordance with the time
`ratio between the idte period and the frame (compressed
`mode frame) transmi-ssion timing, and therefore, dS shown j-n
`FIG. 36, the compressed mode frame is transmitted at a
`frame in normal
`transmission power than the
`higher
`transmission. As a Consequence, transmission quality can
`be maintained even in frame transmission in compressed mode.
