Abstract: A transmitting station receives a transmit power command and a reference signal. The transmit power command indicates an increase or decrease in transmission power for the transmitting station. A received power level of the reference signal is measured and the measured reference signal received power level is compared to a transmit power level of the reference signal to produce a pathloss estimate of the reference signal. A size of a change in transmit power level is determined using the pathloss estimate. A transmission power level of the transmitting station is adjusted in response to the transmit power command in an amount of the determined change in size. A communication is transmitted at the adjusted transmission power level.

Abstract: The method employing weighted open loop power control in a base station is initiated by the base station 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 base station is based, in part, on weighting the path loss estimate in response to the quality of the estimate.

Abstract: A transmission power level for a user equipment in a wireless time division duplex communication system using code division multiple access is determined. An interference level is measured. A pathloss estimate is determined. A long term average of pathloss estimates is determined. A first weighting factor, null, is determined by the determined pathloss estimate, producing a weighted pathloss estimate. (1nullnull) is multiplied to the determined long term average of pathloss estimates, producing a weighted long term pathloss estimate. A transmission power level of the user equipment is determined by adding the weighted pathloss estimate to the weighted long term pathloss estimate to the measured interference level to a target signal to interference ratio to a constant value.

Abstract: An ACK/NACK method and system for use in time division duplex (TDD) and frequency division duplex (FDD) systems. In high speed downlink packet access (HSDPA), based on the assignment of timeslots for the high speed shared information channel (HS-SICH), each user equipment (UE) can be assigned two (2) different channelization codes. It is then possible to adopt the signaling convention that one code represents acknowledge error-free (Ack) and the other code shall represent acknowledge error condition (Nack). The Node B is able to distinguish the presence of the transmitted channelization code as opposed to the channelization code which is not transmitted. The probability of error, using this invention is an order of a magnitude smaller than if the Ack/Nack were signaled using typical modulation techniques.

Abstract: A criterion for biasing a binary decision requiring an unequal protection which utilizes a measured signal to interference ratio (SIR). The SIR may be derived from a determination of channel estimation. The SIR is compared against a threshold, the threshold being selected to bias the decision toward a NACK as opposed to an ACK determination. The technique is advantageous for providing biased binary decisions for high speed downlink packets (HSDP) but may be utilized for both uplink and downlink applications.

Abstract: A system and method in a wireless communication network that efficiently determine when a message is intended for a particular wireless transmit/receive unit (WTRU). In accordance with the present invention, each WTRU is configured to receive communications on multiple communication channels. The WTRU receives and processes incoming signals on the multiple communication channels at the physical layer for an indication of which, if any, of the multiple communication channels is intended for the WTRU. If the indication is consistent with an expected indication for that mobile unit, the mobile unit accesses the particular communication channel and processes the information being sent therein.

Abstract: 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.
