摘要： A wireless hybrid time division multiple access/code division multiple access (TDMA/CDMA) user equipment (UE) includes a signaling receiver and a data detection device in communication with the signaling receiver. The signaling receiver is configured to receive and recover signaled information of code and timeslot assignments of the UE to support an RF communication. The data detection device is configured to recover from the signaling information an identifier of a plurality of assigned timeslots and an indication of a first and last code of a set of consecutive codes. The last code is identified by an identifier associated with the last code.

摘要： A method of using a mobile unit in a multi-cell communication system to determine whether to commence handover of the mobile unit from a serving base station located in a first cell of the communication system to a target base station located in a second cell of the communication system. The mobile unit determines the serving base station received signal code power (RSCPser), the first cell interference signal code power (ISCPser), the target base station received signal code power (RSCPtar) and the second cell interference signal code power (ISCPtar). If the ratio RSCPser/ISCPser is less than the ratio RSCPtar/ISCPtar, the mobile unit commences handover to the target base station. The multi-cell communication system may be a time division duplex (TDD) system. The mobile unit may send a message to a radio network controller (RNC) in communication with the serving and target base stations to initiate the handover.

摘要： A method for reporting channel quality from a user equipment (UE) to a base station is described. The UE derives a channel quality for each of a plurality of downlink resources. The UE transmits channel quality reports in a pattern of time intervals by rotating through the plurality of downlink resources in different time intervals of the pattern, wherein a channel quality report is not transmitted by the UE in each time interval of a frame.

摘要： A method for downlink power control for use in a spread spectrum time division communication system having time slots for communication, implemented in a user equipment, includes receiving data in a command per coded composite transport channel (CCTrCH) transmitted over a plurality of time slots. An interference power for each time slot of the plurality of time slots is measured and a single power command for the entire CCTrCH is transmitted in response to a signal to interference ratio of the received CCTrCH and the measured interference power measurement for each time slot. A subsequent data is received in the CCTrCH communication having a transmission power level for each downlink communication time slot set individually in response to the interference power measurement for that time slot and the single power command for the entire CCTrCH.

摘要： A wireless digital communication system includes a base station in communication with a plurality of user equipment mobile terminals (UEs). The system prioritizes the forwarding of blocks of downlink data to designated ones of the UEs. The system employs adaptive modulation and coding (AM&C) to achieve improved radio resource utilization and provides optimum data rates for user services. Blocks of downlink (DL) data are received by the base station which requests downlink (DL) channel quality measurements only from those mobile terminals (UEs) with pending downlink transmissions. The UEs respond to the request by measuring and reporting DL channel quality to the base station, which then allocates resources such that the UEs will make best use of radio resources. The base station notifies the UEs of the physical channel allocation indicating the modulation/coding rate and allocated slots followed by transmission of blocks of downlink data which are transmitted to the UEs.

摘要： A user equipment (UE) for a wireless time division duplex communication system which uses code division multiple access. The system communicates using communication bunts that have unique channelization codes and corresponding midamble codes where each midamble code is uniquely related to one or more channelization codes. The UE has a midamble detector which detects each midamble code in a received communication burst. A logic block determines the channelization codes related to each detected midamble and a channelization code detector detects channelization codes from among channelization codes determined by the logic block. A multiuser detection device recovers data from the received communication burst based on the detected channelization codes. Where all midamble codes are uniquely related to one channelization code, the channelization code detector is not needed.
