摘要： Various schemes for reducing effects of interference within communication systems are disclosed. A transmitter transmits a signal in a first time interval and a scrambled version of the signal in a second time interval, which does not overlap with the first time interval. A receiver receives a composite signal including a signal transmitted from the desired transmitter as well as signals from interferers in the first or the second time interval. The receiver determines a dominant interferer and obtains knowledge of signal scrambling done by the interferer as well as the desired transmitter by sensing an identification associated with the interferer or the desired transmitter. This knowledge is employed to determine coefficients for combining the received composite signals received in the first and the second time interval in order to recover the desired signal in a manner that maximizes the SNR associated with the desired signal or completely cancels the dominant interference.

摘要： A method and system are provided that allows a wireless terminal to share an allocated frequency spectrum for communications over two different networks while mitigating cross interference. For wireless terminals equipped with a single antenna, interference mitigation may be achieved by allocating first communication channels to a first network and allocating second communication channels to a second network, wherein the second communication channels are allocated within one or more of the first communication channels. For wireless terminals having multiple antennas, interference mitigation may be achieved with two orthogonally polarized antennas, where each antenna is used for communications with a different network. Consequently, a wireless terminal having a channel allocation for communicating over the first wireless network may reuse the same channel allocation to establish a communication link with a second wireless terminal via a second wireless network using at least part of the channel allocation for the first wireless network.

摘要： Methods and apparatus of efficient communication of resource allocation are described. A base station transmits a resource assignment message, e.g., a state transition message, to a wireless terminal including a first part, e.g., a base station assigned wireless terminal On state identifier, identifying a resource being assigned and a second part, e.g., an ON state mask, identifying a portion of the resource allocated to the wireless terminal. The same resource allocation message information also communicates one of a plurality of different modes of commanded On state operation. The resource allocation message structure supports flexible allocation of available resources facilitating a resource to be partitioned differently at different times accommodating current needs. A predetermined recurring channel structure and association of segments with particular mask bits, facilitates allocated control segments to be used unambiguously without the need to include an overhead wireless terminal identifier field with the control report bits being communicated.

摘要： Wireless terminals and base stations support multiple modes of dedicated control channel operation wherein wireless terminals are allocated different amounts of dedicated uplink resources for reporting control information. A set of dedicated control channel segments is utilized by a wireless terminal to communicate uplink control information reports to its serving base station attachment point. Full tone and split-tone modes of dedicated control channel operation are supported. In full tone mode, a single wireless terminal is allocated each of the dedicated control channel segments associated with a single logical tone. In split tone mode, dedicated control channel segments associated with a single logical tone are allocated between different wireless terminals, with each of the multiple wireless terminals receiving a different non-overlapping subset of the dedicated control channel segments. Logical dedicated control channel tones can be dynamically reallocated for full-tone mode use or split.tone mode use.

摘要： Methods and apparatus related to assignments in a wireless communications system are described. A mobile is assigned an identifier and a mask value, e.g., as part of a state transition message. The mobile uses the assigned identifier and/or the assigned mask value in determining whether assignments included in assignment messages, e.g., traffic channel assignment messages, are directed to the wireless terminal. Predetermined associations between assignment slots, assigned segments, and/or mask values are utilized to limit control signaling overhead. Different groups of segments are available for assignment to different wireless terminals as a function of mask values. Different types of assignment messages use different amounts of information bits to convey the assignment. Some types of assignments use a wireless terminal identifier, while other types of assignments use a wireless terminal identifier and a mask identifier. The mask identifier, e.g., a single bit, allows for selection between a subset of the potential masks used in the system.

摘要： Methods and apparatus related to the sharing of wide area network (WAN) uplink bandwidth with peer to peer communication signaling usage are described. The base station regulates the level of interference from the peer to peer signaling by generating and transmitting peer to peer transmission power control signals intended for peer to peer wireless terminals in the local vicinity. A base station transmits into a downlink frequency band a signal, e.g., a beacon or broadcast channel signal, to be used by a peer to peer wireless terminal in controlling its peer to peer transmit power level into the corresponding uplink frequency band. The peer to peer wireless terminal receives and evaluates the base station signal. The determined information from the evaluation is used in determining whether or not peer to peer signal transmission is permitted and/or in determining a peer to peer transmission power level.

摘要： Techniques for paging terminals in a wireless (e.g., OFDMA) communication system to achieve both fast paging response and low power consumption for the terminals are described. A terminal receives paging indicator from a base station. If the paging indicator indicates that the terminal is potentially being paged, then the terminal receives at least one paging message from a paging channel. The terminal determines whether any one of the at least one paging message is for the terminal, e.g., based on identification information included in each paging message. If a paging message indicates that the terminal is paged, then the terminal sends an acknowledgement for the paging message. The base station may estimate the timing of the terminal based on the acknowledgement and may send timing adjustment to the terminal. The terminal may adjust its timing based on the timing adjustment and may be able to quickly access the system with no contention.
