Abstract: A transmitting station performs closed loop power control prior to a transmission pause. A closed loop transmission power level prior to the pause is determined. A reference signal is received and a received power level of the reference signal prior to and during the transmission pause is determined. The measured reference signal received power levels are compared to a transmit power level of the reference signals to produce a pathloss estimate of the reference signal prior to and during the transmission pause. A new transmit power level is determined by adjusting the closed loop transmission power level by a change between the prior to and during pathloss estimates. A transmission power level of the transmitting station is set to the determined new transmit power level. A communication is transmitted at the set transmission power level.

Abstract: A wireless communication system is configured to monitor transmission sequence numbers (TSNs) assigned to protocol data units (PDUs) processed by the system. The system includes at least one user equipment (UE) (605) having, a queue, and a Node B (615) in communication with the UE. The UE determines that a data block having an expected TSN was not received, and generates a TSN status report message (625). The Node B retransmits a data block (630) including the expected TSN to the UE in response to the TSN status report message. The retransmitted data block is placed in a specific location in the queue designated by the TSN status report message.

Abstract: A criterion for biasing a binary decision requiring an unequal protection (Fig 1) 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: 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 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 (901) and determines an error rate (902) on the received communication. The system then distinguishes between static and dynamic channels, produces a static adjustment value (908), 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 (912).

Abstract: A wireless communication method and apparatus for decoding an enhanced uplink dedicated channel (E-DCH) absolute grant channel (E-AGCH) transmissions are disclosed. A wireless transmit/receive unit (WTRU) receives E-AGCH data which includes a cyclic redundancy check (CRC) part and a data part. The CRC part is masked with a WTRU identity (ID) at a Node-B. The CRC part and the data part are demultiplexed and the CRC part is demasked with the WTRU ID. A CRC is then performed with the demasked CRC part. If the CRC passes the data part is sent to an enhanced uplink medium access control (MAC-e) entity. The WTRU ID may be a primary E-DCH radio network temporary identity (E-RNTI) or a secondary E-RNTI. When the E-AGCH data is transmitted over a 10ms frame, if the CRC fails, E-AGCH data via subsequent subframe may be soft combined with the previous E-AGCH data.
