摘要： Techniques for controlling receive diversity on a wireless device are disclosed. In one aspect, one or more thresholds are determined based on one or more parameters. One or more other parameters are compared against the one or more thresholds to determine whether to enable or disable receive diversity. For example, a wireless device may determine a threshold value based on a first parameter related to communication of the wireless device. The wireless device may decide to enable or disable receive diversity based on a second parameter and the threshold value. The wireless device may receive data transmission with receive diversity when a decision is made to enable receive diversity. The first parameter may relate to characteristics of data being received by the wireless device and may be represented by percentage downlink utilization. The second parameter may relate to channel conditions and may be represented by an improvement in received signal quality with receive diversity enabled.

摘要： A method, an apparatus, and a computer program product for data communication are provided. The method may include providing a frame of encoded data, generating a synchronization symbol to precede the encoded data when the frame is transmitted over a communication link, the synchronization symbol providing an identification of a type of the frame in accordance with an encoding scheme. The synchronization symbol may be encoded using a redundant coding scheme to support error correction for the identification of the type of frame. The frame may have a predefined fixed length.

摘要： Aspects of the disclosure provide techniques for improving uplink transmit power control at a user equipment (UE). When the UE is communicating with multiple cells using Multi-flow High-Speed Downlink Packet Access (MF-HSDPA), the UE may control its uplink power based on an improved MF-HSDPA uplink power control algorithm, which is different from an or-of-downs (OOD) transmit power control. In handover, a UE may determine its transmit power to be less than a transmit power requested by a high-speed cell and more than an OOD transmit power.
