  • Patent number: 8346173
    Abstract: A method and system facilitate inter-cell interference cancellation in a wireless network. An RNTI component manages a set of radio network temporary identifiers (RNTIs) for a plurality of user equipment (UE). The RNTI component determines whether the UEs will likely cause interference with a neighboring cell and/or experience interference from a neighboring cell, based on a respective attribute of the UEs. The RNTI component includes a space splitting component that divides the set of RNTIs into at least two subsets based on the determination, and allocates a first group of the UEs that are determined to likely cause interference and/or experience interference to a first subset of the divided RNTIs, such that the UEs in the first group are allocated a corresponding one of the RNTIs among the first subset of RNTIs. An implicit broadcast component can implicitly broadcast the first subset of RNTIs to facilitate cancellation of interference possibly caused by the first group of UEs.

  • Patent number: 8203992
    Abstract: A method for efficiently transmitting control information may include allocating a portion of orthogonal frequency division multiple access (OFDMA) frames for transmission of a code division multiple access (CDMA) based signal. The CDMA-based signal may include data from one or more dedicated control channels. The method may also include converting the CDMA-based signal into a format that is suitable for transmission via OFDMA techniques. The method may also include transmitting the converted CDMA-based signal using a subset of available OFDMA subcarriers.

  • Patent number: 8185138
    Abstract: Certain embodiments of the present disclosure provide a paging schedule that may allow a WiMAX mobile device to return to a low power state prior to the end of a listening interval, thereby reducing power consumption. For certain embodiments, the paging schedule may be controlled by a base station using standardized paging messages, with paging messages targeting particular MSs in a group presented in an organized manner within a listening interval. An MS aware of this schedule may, thus, promptly return to a low power state prior to the end of a listening interval if it does not detect a paging message at its expected time within the listening interval.

  • Patent number: 8185140
    Abstract: In accordance with a method for supporting short burst messages over a wireless communication network, mobile-originated short burst messages may be sent using at least one of a message-based approach and a service flow-based approach. Also, mobile-terminated short burst messages may be received using at least one of the message-based approach and the service flow-based approach.

  • Patent number: 8174995
    Abstract: In accordance an aspect, a method for a wireless communication system, determining a location in time of a sub-frame when SFN transmission for data will occur, determining a first transmission pattern and a second transmission pattern for reference signals, wherein the transmission patterns indicate the symbols and tones of a sub-frame to use for reference signals, selecting for use, between the first transmission pattern and second transmission pattern for reference signals depending on whether SFN data will be transmitted in the sub-frame, and broadcasting information about the selected transmission pattern prior to use thereof.
