摘要： Techniques for transmitting information using beacon symbols are described. A transmitter may map first information to at least one subcarrier in a first set of subcarriers, with the first information being conveyed by the position of the at least one subcarrier. The transmitter may map second information to one or more subcarriers in a second set of subcarriers. The second information may be conveyed by one or more modulation symbols sent on the one or more subcarriers. The transmitter may generate at least one beacon symbol having the first information mapped to the at least one subcarrier in the first set and the second information mapped to the one or more subcarriers in the second set. In one design, the transmitter may frequency division multiplex the first information with the second information. In another design, the transmitter may puncture the second information on the at least one subcarrier with the first information.

摘要： A method and apparatus for sector specific scrambling in a wireless communication system are described. A complex number for every subcarrier in every OFDM symbol in a superframe is assigned, wherein k=0, 1…, N CARRIER-1 . It is determined if the subcarrier corresponds to a forward dedicated pilot channel (F-DPICH) hop-port. Complex symbols on each subcarrier are multiplied by corresponding to the forward dedicated pilot channel (F-DPICH) hop-port with a sector-specific scrambling sequence.

摘要： In a single-carrier frequency division multiple access (SC-FDMA) system, a receiver receives transmission symbols from a transmitter, determines a set of subbands used by the transmitter, processes the received transmission symbols for the set of subbands, obtains received pilot values for a transmitted pilot, and obtains received data values for transmitted data. The receiver may iteratively perform channel and interference estimation for the transmitter. The receiver selects an initial interference estimate, derives a channel estimate based on the received pilot values and the interference estimate, and derives a new interference estimate based on the received pilot values and the channel estimate. The receiver may repeat the derivation of the channel estimate and the interference estimate for multiple iterations. The receiver then performs data detection and/or receiver spatial processing on the received data values based on the channel estimate and the interference estimate.

摘要： In a cellular wireless communication system, peer-to-peer (P2P) links between mobile devices are implemented, and controlled using an aggregate utility metric for a group of P2P and cellular links. A mobile node participating in a P2P link, or an eNB, may periodically broadcast an activity level indicator indicating a resource-dependent activity level of the link. The node may control the activity level in response to utility metrics received from members of neighboring P2P links to maximize an aggregate utility of the link and the neighboring P2P links sharing at least a subset of resources of a common frequency spectrum. Formation or termination of P2P links may be controlled in response to comparing a calculated achievable utility value to a current utility value of a link, and taking action calculated to maximize the aggregate utility value.

摘要： A hierarchical cyclic redundancy check (CRC) is provided that enables CRC appending and detection. A message that includes a first message portion and a second message portion is transmitted to two or more receivers. The receivers are not aware of the first message portion. One of the receivers can be aware of the second message portion of the message. Each portion of the message can be encoded with a CRC in order to provide protection. The receiver that is aware of the second message portion is provided a higher level of cyclic redundancy check (CRC) protection than the receivers that are not aware of the second message portions.
