    摘要: Rather than attaching a preamble to a data traffic subpacket, a preamble channel is transmitted along with a traffic channel. In a system wherein the data traffic subpackets are variably sized, preambles can also be variably sized if a target station can decode variably sized preambles. A method and apparatus for decoding variably sized preamble subpackets are presented herein.

    摘要: Aspects describe channel estimation in an OFDM system. Baseline DFT-based channel estimation can be performed and scaling can be applied to mitigate distortion in the DFT-based estimations. In some aspects, baseline DFT-based channel estimation can be performed and tones for which DFT-based estimate is deemed unreliable can have MMSE based processing applied locally. If orthogonal sequence is deemed excessive, orthogonal sequence cancellation can be applied prior to the MMSE based processing.

    摘要: Systems and methods for evaluating packets and frames in a wireless communication system having multiple reverse-link channels including a spontaneous, burst oriented transmission channel and its corresponding rate indicator channel. One embodiment comprises a base station monitoring the rate indicator channel, decoding the rate indicator channel using a maximum likelihood decoder and detecting the presence of a packet on the rate indicator channel by comparing a likelihood with a threshold, and analyzing the validity of a frame on the burst oriented channel based on the presence and content of packets received on the rate indicator channel.

    摘要: Techniques for transmitting data and resource signals (RS) are provided. According to certain aspects, an access point may determine RS resource locations related to one or more access points in a CoMP set transmitting a common reference signal (CRS), map data transmissions initially over resources other than those related to the RS resource locations, and map remaining data transmissions over resources related to the RS resource locations. According to certain aspects, a wireless device may receive a signal from access points in a coordinated multiple point (CoMP) communication set comprising a common reference signal (CRS) superimposed over data, determine CRS locations in the signal that correspond to the CRS, and decode data from the signal based at least in part on the determined CRS locations.
