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 temporary (temp) dedicated channel (DCH) is used to support communications. The temp-DCH channel is a channel that is assigned to a user having a set duration. After the duration expires, the channel is automatically released to the user. Embodiments of the invention relate to establishing the temp-DCH channel, determining the data rate and duration of the channel. Other embodiments relate to establishing back-to-back temp-DCH channels and the implementation details of these embodiments. Additionally, one embodiment relates to adding a start/stop function to the medium access controller which can be used in conjunction with temp-DCH as well as other applications.

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 transmission power level of a selected user is estimated in a code division multiple access (CDMA) communication system. An initial estimate of a transmit power level associated with the selected user is determined. A transmit power level of users of the system other than the selected user is provided. Subsequent estimates for the selected user and the other users are estimated using previous transmit power level estimates of the selected user and the other users. The estimating subsequent estimates is repeated with a last repetition's estimated transmit power levels for the selected and other users being the estimated transmit power levels of the selected and other users.

摘要： A simulation is used to determine the effect of additional users on a communications system, such as a slotted wireless communications system. Users are sequentially added and determinations are made as to whether criteria for the additional user fall within predetermined limits. If the criteria are met, the user is accepted by the simulation and a power balancing is performed for all users. The simulation is repeated for each additional user. If the parameters are not within predetermined limits, the user is dropped. The simulation presents the system in a series of “snapshots” of communications activity.
