    摘要: Methods, systems, and devices are described for receive chain diversity processing in a mobile wireless device. When data is not being received at the mobile device, the diversity receive chain(s) may be disabled in order to reduce power consumed at the mobile device. The diversity receive chain(s) may be enabled/disabled according to one or more different algorithms based on idle time from the receipt and/or transmission of data. The amount of idle time that triggers the disabling of a diversity receive chain may be adaptive based on historical usage of the mobile device, or based on activity on the transmit chain of the mobile device.

    摘要: A method for processing forward link channel signals generated by a CDMA base station includes time sharing by several mobile stations of spreading codes, which are orthogonal codes such as Walsh Code, and code-combining soft/softer handoff across sectors in the mobile station active set to increase dimensions on the CDMA2000 and WCDMA downlink while minimizing intra-sector interference. Since different parts of a packet or frame are transmitted to the user by the different base stations in the active set, earlier decoding and therefore early packet termination is enabled.

    摘要: Techniques for rank adaptation and multiple-stream reverse link communications in a wireless access network are disclosed. A remote unit transmits one or more reverse link data streams using separate identifiers to a base station. The number of reverse link data streams may be determined according to feedback from the base station or it may be determined by testing one or more multiple-antenna transmit hypotheses. The base station may estimate channel conditions using information obtained from the one or more reverse link data streams and may determine a spatial rank of the communication channel. The remote unit may perform separate error control and power control processes for each reverse link data stream in cooperation with the base station.
