    摘要: A method and apparatus for decoding encoded data bits of a wireless communication transmission are provided. A set of a-priori bit values corresponding to known bit values of a response message expected to be transmitted in response to a previously transmitted message. Example expected response messages include clear to send (CTS) messages transmitted in response to request to send (RTS) messages and positive acknowledgement (ACK) messages transmitted in response to messages with data payloads.

    摘要: Methods and apparatus for initially decoding a frame control header (FCH) in an orthogonal frequency-division multiplexing (OFDM) or orthogonal frequency division multiple access (OFDMA) system in an effort to accurately determine the downlink frame prefix (DLFP) such that the remainder of an OFDM/A frame may be properly decoded are provided. Used, for example, when boosting factors applied in the transmitter to various elements of the OFDM/A frame and/or available pilots for the FCH are unknown, such methods may utilize a preamble channel estimate, the FCH pilots, or a combination thereof.

    摘要: Techniques for windowing a transmission are disclosed herein. In one aspect of the disclosure, the length of a window used for windowing may be configurable and determined for a transmission based on a configuration of the transmission. The configuration of the transmission may be determined based on one or more parameters such as a system bandwidth, a bandwidth assigned for the transmission, the location of the assigned bandwidth within the system bandwidth, a modulation type used for the transmission, etc. In another aspect of the disclosure, a preferred length for a window may be determined for each of a number of possible configurations of a transmission. Different possible window lengths may be evaluated for each possible configuration based on one or more performance metrics. For each configuration, a window length that can provide the best performance for that configuration may be selected as a preferred window length for that configuration.

    摘要: A method and apparatus for decoding encoded data bits of a wireless communication transmission are provided. A set of a-priori bit values corresponding to known bit values of the encoded data bits may be generated. Decoding paths that correspond to decoded data bits that are inconsistent with the a-priori bit values may be removed from the possible decoding paths to consider, and decoding the encoded data bits by selecting a decoding path from remaining decoding paths of the possible decoding paths that were not removed. A-priori bit values may be extracted from various messages, such as DL-MAP, UL-MAP, RNG-REQ, and BW-REQ messages.
