Abstract: A method for performing outer loop power control in a wireless communication system utilizing a plurality of transport channels begins by selecting an initial reference transport channel (TrCH) and a final reference TrCH. Outer loop power control is performed using the initial reference TrCH and then outer loop power control is performed using the final reference TrCH.

Abstract: A method for outer loop power control in a wireless communication system begins by determining if a cyclic redundancy check (CRC) is available. If the CRC is available, the method uses the CRC to calculate an adjustment for a target signal to interference ratio (SIR) for a coded composite transport channel (CCTrCH). If the CRC is not available, then quality measurements of the CCTrCH are taken. The quality measurements are used to calculate an adjustment for the target SIR, which is then updated.

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 method and apparatus for implementing hybrid automatic repeat request (H-ARQ) in a multiple-input multiple-output (MIMO) wireless communication system are disclosed. A transmitter transmits at least two data packets via two or more antennas. If at least one of the data packets is not successfully transmitted, the transmitter retransmits the data packets while rearranging the data packets in an orthogonal spreading manner. Alternatively, the transmitter may retransmit only the unsuccessfully transmitted data packet along with a new data packet which replaces a successfully transmitted data packet. The unsuccessfully transmitted data packet may simply be repeated without changing its format. When only the unsuccessfully transmitted data packet is retransmitted along with the new data packet, the transmissions may be combined to recover the retransmitted data packet and the new data packet simultaneously.
