Abstract: A method for improving the reliability of a channel quality indicator (CQI) message in a wireless communications network begins with receipt of the CQI message. The CQI message is then decoded, and a decision metric value for each symbol in the CQI message is computed. A largest decision metric value and a second largest decision metric value for the CQI message are determined. The reliability of the CQI message can be determined by comparing the two largest decision metric values. This method may be applicable to high-speed downlink packet access in time division duplex, frequency division duplex, or other modes of transmission.

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 method and wireless multi-cell communication system for providing high speed downlink packet access (HSDPA) services (FIG. 1). The system includes a radio network controller (RNC) (105) in communication with a plurality of base stations (110, 115 and 120). The RNC sends a control signal (140A, 140B,and 140C) to at least one base station having a plurality of timeslots, e.g., in a time division duplex (TDD) system and/or frames including transmission timing intervals (TTIs), e.g., in a frequency division duplex (FDD) system assigned thereto for the establishment of HSDPA channels. The control signal indicates a maximum allowed HSDPA transmit power for each of the timeslots and/or TTIs. The base station (110, 115 and 120) sends a feedback signal (145A, 145B and 145C) to the RNC indicating the results of measurements of the power of the transmitted HSDPA timeslots and/or TTIs during a predetermined time period.

Abstract: A medium access control (MAC) architecture reduces transmission latency for data block retransmissions. A plurality of data blocks are received and temporarily stored in a first memory (815B) (e.g., queue, buffer). The pluralities of data blocks are then transmitted. A determination is made as to whether each of the transmitted data blocks was received successfully or needs to be retransmitted because the data block was not received successfully. Each of the transmitted data blocks that need to be retransmitted is marked and temporarily stored in a second memory (815A) having a higher priority than the first memory (815B). The marked data blocks are retransmitted before data blocks stored in the first memory (815B) location.

Abstract: A wireless communication method and apparatus for coordinating Node-Bs during handover for enhanced uplink (EU) transmission. In one embodiment, a radio network controller (RNC) initiates an inter-Node-B soft handover. A wireless transmit/receive unit (WTRU) establishes communication connections with a plurality of Node-Bs. A particular one of the Node-Bs is designated as being a primary Node-B, and each of other Node-Bs are designated as being a non-primary Node-B. The RNC informs all of the Node-Bs that the particular Node-B is a primary Node-B. The primary Node-B schedules EU transmission and performs ACK/NACK during soft handover. In another embodiment, the RNC initiates a hard handover for a WTRU connected to a source Node-B. The RNC sends an activation timer to the source Node-B to set the time for handover. As many previously negatively acknowledged (NACKed) data packets as possible are prioritized for retransmission in the source Node-B before the activation timer expires.
