摘要： Accordingly, a method and apparatus are provided that use implicit de-assignment, instead of explicit deassignment, of resources, such that a mobile terminal can interpret the assignment of the resources to other channel terminals as an implied deassignment of the resources. Thus, reducing the number of assignment or the assignment between the base station and the terminals.

摘要： Techniques are provided to support fast frequency hopping with a code division multiplexed (CDM) pilot in a multi-carrier communication system (e.g., an OFDMA system). Each transmitter (e.g., each terminal) in the system transmits a wideband pilot on all subbands to allow a receiver (e.g., a base station) to estimate the entire channel response at the same time. The wideband pilot for each transmitter may be generated using direct sequence spread spectrum processing and based on a pseudo-random number (PN) code assigned to that transmitter. This allows the receiver to individually identify and recover multiple wideband pilots transmitted concurrently by multiple transmitters. For a time division multiplexed (TDM)/CDM pilot transmission scheme, each transmitter transmits the wideband pilot in bursts. For a continuous CDM pilot transmission scheme, each transmitter continuously transmits the wideband pilot, albeit at a low transmit power level. Any frequency hopping rate may be supported without impacting pilot overhead.

摘要： Techniques for selecting a reverse link (RL) serving base station for a terminal are described. The terminal sends a transmission on the reverse link to multiple base stations in a wireless communication system. The transmission may be for signaling sent on a control channel. The terminal receives feedback (e.g., power control (PC) commands and/or erasure indications) from the multiple base stations. Each base station may generate feedback based on the control channel and/or some other transmission received from the terminal. The terminal performs reverse link power control and further selects an RL serving base station based on the received feedback. For example, the terminal may select the base station with the lowest transmit power level, the largest percentage of power down commands, or the lowest erasure rate as the RL serving base station.

摘要： For soft handoff on the reverse link with restrictive reuse, a wireless terminal searches for pilots transmitted by sectors in a wireless system, measures the detected pilots, selects a serving sector (e.g., the strongest received sector), and identifies non-serving sectors that may receive high interference from the terminal. The serving sector assigns the terminal with subband(s) that are usable by the serving sector and unusable by the non-serving sectors. The terminal transmits data symbols on the assigned subbands to the serving and non-serving sectors. These sectors process the reverse link transmission from the terminal and obtain soft-decision symbols, which are estimates of the transmitted data symbols. The soft-decision symbols from co-located sectors may be combined and then decoded to obtain decoded packets. The sectors may also independently decode the soft-decision symbols, and the decoded packets from these sectors may be combined to obtain final decoded packets for the terminal.
