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.

摘要： Systems and methodologies are described that facilitate distributing and utilizing interference information in a wireless communication environment. Interference information can be generated by a base station by evaluating uplink conditions, and disparate interference information can be collected from neighbor base station(s). Interference information associated with the base station and the neighbor base station(s) can be transmitted by the base station to access terminal(s). An access terminal that receives that interference information associated with the base station and the neighbor base station(s) can control an operation based at least in part upon the interference information. For example, the access terminal can adjust a transmit power, select a target serving base station for handover, and/or choose a random access channel (RACH) resource to use for random access as a function of the interference information associated with the base station and the neighbor base station(s).

摘要： Apparatus and methods are provided for enabling communication on an enhanced access channel (EACH) without necessitating the additional features or channels usually implemented along with this capability. To this end, control information corresponding to the EACH transmission may be provided to an access terminal on a paging channel (PCH). For example, a base station may broadcast a general access parameters message (GAPM) to enable the access terminal to configure EACH transmissions. Further, the PCH may carry acknowledgment messages to inform the access terminal of the status of the EACH transmissions. Other aspects, embodiments, and features are also claimed and described.
