摘要： A system and method for random access channel (RACH) capture, where user equipment (UE) transmits a series of time-spaced access preambles each having an increasing power level to Node B and terminates access preamble transmission in response to an acquisition indicator (AI) signal returned from Node B and transmits its RACH message part. A collision detection preamble (CDP) is sent immediately after the message or embedded with the message. A collision detection indicator (CDI) signal matching the CDP is transmitted from Node B to the UE identified as having the failed RACH message requesting retransmission of the message. Optionally, the relative retransmission power level is also specified to the UE along with the CDI signal.

摘要： A wireless communications network has a plurality of terminals and at least one base station which transmits data to each one of said plurality of terminals on a wireless downlink and receives data from each one of said plurality of terminals on a wireless uplink. One of the terminals sends a rate request to the base station. The rate request requests that the data rate on the wireless uplink for the terminal be changed. In response to the rate request, the base station sends a rate grant to the terminal. The rate grant indicates whether or not the terminal may change the data rate on the wireless uplink.

摘要： Apparatus, and an associated method, for facilitating selection of optimal antenna weightings by which to weight signals sent in a communication system that utilizes closed-loop transmit diversity. A deterministic perturbation gradient approximation technique is utilized in which perturbation vectors are selected by a selector and applied, by an applicator, to antenna weighting elements. A selected set of perturbation vectors are applied to the antenna weighting elements in both a positive direction and a negative direction. A detector at a receiving station measures in disassociated with the signals communicated thereto, once weighted with the perturbation vectors. A single-bit feedback value is returned to the sending station, and the antenna weightings are appropriately adjusted. The technique is utilized during both non-handoff conditions and during handoff conditions.
