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 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： The present invention is a user equipment (UE) which receives a communication signal over a physical reference channel using a reference channel receiver. An expected path loss is calculated using a path loss calculation device in response to the received communication signal. A signaling receiver receives an allocation of an uplink control channel including the amount of interference in the channel. Then, a power level calculation device, responsive to the path loss calculation device and the signaling receiver, determines an uplink power level based on the path loss and the interference level, whereby an uplink control channel transmission is initiated having the power level determined by the power level calculation device.

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： The present invention is a method and system for controlling downlink transmission power levels in a spread spectrum time division communication system having frames with time slots for communication, which receives at a user equipment (UE) a downlink communication from a base station and determines an error rate of the received communication. The UE then produces power level adjustments for each of the time slots based in part on the error rate and transmits an uplink communication to the base station which includes the power level. In response to the power level adjustments and (or) other information, transmission power level is set for each time slot in the downlink communication.
