    摘要: In a wireless communications network, a wireless device may examine the received signal to determine the strength of the received signal, and also determine the level of interference and noise. If a retransmission is needed due to a message being incorrectly received, these factors may then be processed to estimate whether the probable cause of poor reception is interference from a neighboring network. If such interference is the likely cause, the retransmission may be changed to a different time and/or to different frequencies in a subsequent frame, so that the interference from the neighboring network is less likely to reoccur.

    摘要: In various embodiments of the invention, a relay station in a wireless communications network may communicate with one or more subscriber stations at the same time and/or on the same frequency that the associated base station is communicating with another relay station in the same network. This contrasts with the conventional technique of devoting one time period or frequency exclusively to communications between the base station and the relay stations, and devoting another time period or frequency exclusively to communications between the relay stations and the subscriber stations.

    摘要: Techniques are described that can be used to determine a transmitter power level of a mobile station based on spectrum efficiency gain and loss. Spectrum efficiency gain is measured for a home sector base station. Spectrum efficiency loss is measured for base stations other than the home sector base station. In one example, a base station transmits information such as noise plus interference level to a mobile station and the mobile station determines the transmitter power level. In another example, the mobile station transmits information such as preamble signal strength and preamble total signal strength to the home sector base station and the home sector base station determines the transmitter power level and instructs the mobile station to apply the determined transmitter power level.

    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. Using a bipartite graph method for OFDMA sub-channel allocation may improve the time and complexity when establishing an OFDMA wireless system.

    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.
