    摘要: A method and apparatus for calculating an optimal sub-channel allocation of Orthogonal Frequency Division Multiple Access (OFDMA) from a first bipartite graph that may map users, to a second bipartite graph that may map additional users, including original users. A calculation of each bipartite graph may include a calculation of maximum weight paths and matchings.

    摘要: Disclosed is a method for improving power efficiency of subscriber stations in a communication network. A subscriber station is uniquely identified by a base station using a connection Identifier (CID). The method includes splitting CIDs of subscriber stations to form a plurality of first parts and a plurality of second parts. The method includes generating an index including a plurality of entries and transmitting the index to a plurality of subscriber stations by the base station. One or more subscriber stations switch to a power-saving mode on absence of a match between each entry of the plurality of entries with an equivalent part of CIDs associated with the one or more subscriber stations, thereby conserving power and improving power efficiency of the subscriber station. Further, at least one information element in a sub-MAP message may be compressed to reduce overhead.

    摘要: Machine-readable media, methods, apparatus and system for transmitting ACK/NACK signal in a wireless communication system are described. In some embodiments, a sequence corresponding to one of acknowledge (ACK) information and non-acknowledge (NACK) information may be determined. Then, the sequence may be mapped onto a transmission channel for later transmission from the mobile station to a base station. In some embodiments, the transmission channel may be allocated with at least a part of three feedback mini-tiles (FMTs), wherein each of the FMTs comprises two subcarriers contiguous in frequency domain by six orthogonal frequency division multiplexing (OFDM) symbols contiguous in time domain and the three FMTs being discontinuous in frequency domain.

    摘要: Embodiments of a base station and methods for allocating uplink bandwidth using SDMA are generally described herein. In some embodiments, uplink bandwidth request messages are received on a bandwidth request contention channel from one or more subscriber stations. The uplink bandwidth request messages are generated by the subscriber stations by modulating pilot subcarriers of a randomly selected disjoint pilot pattern with a randomly selected orthogonal sequence. The base station allocates uplink bandwidth to the subscriber stations when the uplink bandwidth request messages are successfully detected and decoded. The base station uses an SDMA technique to determine channel responses based on the orthogonal sequences to detect and decode the uplink bandwidth request messages.

    摘要: Embodiments provide techniques for power control. For instance, a method exchanges one or more transmissions with a remote device in accordance with a retransmission protocol. In addition, a power control message is exchanged with the remote device through at least one of the one or more transmissions. Thus, closed loop power control may be performed through retransmission protocol communications.
