摘要： Techniques for delivering data recovered by a HARQ entity in proper order to higher layers in a CDMA system. In a method, packets are received from the HARQ entity by the re-ordering entity and missing packets among the received packets are detected. Packets may be transmitted in a sequential order based on transmission sequence numbers (TSNs) assigned to the packets, and missing packets may be detected based on the TSNs of the received packets. Delivery of received packets later than the missing packets are stalled because higher layers expect data in-order. A determination is thereafter made whether each missing packet is (1) subsequently received from the HARQ entity or (2) lost, by successively eliminating HARQ channels that may be used to send the missing packet. Received packets previously stalled by each missing packet are delivered after the missing packet is determined to be lost or received.

摘要： Method and apparatus for reducing interference in a wireless communication system when the source of interference is a deterministic component of the system. In one embodiment, the receiver weights the transmitters according to when the source of interference is transmitted. Further, the transmitter may employ power boosting to overcome the source of interference. In one embodiment, a W-CDMA system transmits a sync channel concurrently with physical channels, wherein the sync channel is not orthogonal to the physical channels. The receiver may cancel the sync channel when receiving control or data information. Similarly, the receiver may weight the transmissions from multiple transmitters.

摘要： Techniques to mitigate the effects of link imbalance for the uplink between a terminal (or UE) and multiple base stations (or Node Bs). In one aspect, the serving base station (i.e., the one designated to transmit packet data to the terminal) monitors the uplink received SNR for each terminal designated to receive packet data transmission. The serving base station then determines, based on the uplink received SNR and an SNR threshold, whether or not link imbalance potentially exists for each such terminal. In another aspect, if it is determined that link imbalance potentially exists, then a 3-way handshake is performed to check the reliability of a feedback mechanism used for packet data transmission. Appropriate responsive actions may then be performed based on the result of the check.

摘要： A method and apparatus provides for efficient use of communication resources in a CDMA communication system (100) by selecting, at a time prior to a first time period (401), a first mobile station to receive transmission during the first time period (401) on a downlink shared channel, and selecting, at a time prior to the first time period (401), a second mobile station to receive transmission during a second time period (402) on the downlink shared channel. Transmission power level of a downlink shared control channel is determined for transmission to the second mobile station during an overlapping time period (403) with the first time period (401), and the transmission power level of the downlink shared channel for transmission during the first time period (401) is determined based on at least the determined transmission power level of the downlink shared control channel during the overlapping time period (403).
