摘要： A spread spectrum time division duplex user equipment uses frames having time slots for communication. The user equipment receives power commands and a first communication having a transmission power level in a first time slot. A power level of the first communication is measured as received. A pathloss estimate is determined based on in part the measured received first communication power level and the first communication transmission power level. A transmission power level for the second communication in a second time slot form the user equipment is set based on in part the pathloss estimate weighted by a quality factor adjusted by the power command. The quality factor decreases as a number of time slots between the first and second time slots increases.

摘要： The present invention is a system and method which controls outer loop transmit power for transmission power of an uplink/downlink communication in a spread spectrum time division communication. The system receives a communication from a base station and determines an error rate on the received communication. The system then distinguishes between static and dynamic channels, produces a static adjustment value, and characterizes the dynamic channels to generate a dynamic adjustment value. The target power level is then adjusted by the static and dynamic adjustment values, setting the transmission power level.

摘要： A user equipment (UE) employs weighted open loop power control by receiving a communication and measuring its received power level. Based on, in part, the received communication's power level and the communication's transmission power level, a path loss estimate is determined. A quality of the path loss estimate is also determined. The transmission power level for a communication from the UE is based, in part, on weighting the path loss estimate in response to the estimate's quality.

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.

摘要： A sequence of codes are provided for potential assignment to a user in a wireless hybrid time division multiple access (TDMA)/code division multiple access (CDMA) communication system. At least one timeslot is selected to support the communication. For each selected timeslot, at least one code is selected. If more than one code is selected, the selected codes are consecutive in the provided codes sequence. For at least one of the selected timeslots, an identifier of a first and last code of the selected consecutive codes is signaled. The user receives the signaled identifier and uses the selected consecutive codes, as identified, to support the communication.

摘要： A TTD system implements dynamic link adaptation by adding or changing control information to notify the receiver which timeslots and codes are currently active and which timeslots should be avoided. The system synchronizes the transmitter and the receiver such that the receiver knows which timeslots and codes the transmitter has used to map the coded composite transport channel onto physical channels. The system attempts to avoid the timeslots which are experiencing transmission difficulties, while attempting to utilize the timeslots which are not experiencing transmission problems.

摘要： A UE system implements dynamic link adaptation by adding or changing control information to notify a receiver which timeslots and codes are currently active and which timeslots should be avoided. The UE provides synchronization such that the receiver knows which timeslots and codes the UE has used to map the coded composite transport channel onto physical channels. The UE attempts to avoid the timeslots which are experiencing transmission difficulties, while attempting to utilize the timeslots which are not experiencing transmission problems.
