摘要： Systems and methodologies are described that facilitate transmitting control information in wireless networks. Portions of bandwidth can be blanked for transmitting control information, and the control information transmitters can utilize beacon symbols to convey the control information. In this regard, interference is mitigated with respect to data transmissions over the control information bandwidth. Selected frequencies of the beacon symbols in a codeword can be used to indicate the control information. The codewords can be encoded with an error control code to provide redundancy for decoding in the presence of some interference.

摘要： A quick paging channel in a random access wireless communication system includes at least one bit in a quick paging frame identifying the presence of a paging message for an access terminal or group of access terminals. The quick paging bits identifying the presence of a paging message for a first access terminal is encoded with one or more quick paging bits corresponding to one or more additional access terminals to produce one or more forward error correction bits. The jointly encoded quick paging bits are broadcast to the access terminals by time division multiplexing the quick paging frame with additional frames of information.

摘要： Systems and methodologies are described that facilitate mitigation of interference in a wireless communication environment. Terminals can utilize interference information provided by neighboring sectors to adjust transmit power and reduce interference. Access points can provide two sets or types of interference information. The first type can be transmitted over a large coverage area, requiring significant overhead and limiting the transmission rate. Access points can also provide a second set or type of interference information directed at smaller coverage area, such as an area proximate to the edge of the supported sector. This second type of interference information can be utilized by terminals that include the access point within their active set. The second set of interference information can be provided at a higher rate than the first set due to decreased overhead requirements. Terminals can utilize both sets of interference information to adjust transmit power.

摘要： Techniques to transmit data with cyclic delay diversity and pilot staggering are described. For cyclic delay diversity, OFDM symbols having different cyclic delay durations are generated. The cyclic delay durations for the OFDM symbols may be selected to be time varying with respect to the cyclic delay durations for OFDM symbols transmitted by a neighboring base station. An FDM pilot is generated and multiplexed on multiple sets of subbands in different symbol periods. Waveforms for a second radio technology (e.g., W-CDMA) may be generated for data to be transmitted with this radio technology. The OFDM symbols are multiplexed onto time slots used for OFDM, and the waveforms for the second radio technology are multiplexed onto time slots used for this radio technology. One or multiple modulated signals may be generated based on the multiplexed OFDM symbols and waveforms. Each modulated signal is transmitted from a respective antenna.

摘要： Method and apparatus for transmission of information in multiple access communication system is claim. Information using incremental redundancy is transmitted. A determination is made as to whether reverse link performance drops below a predetermined threshold. Determination of reverse link performance may be done in variety of ways, including use of a filter percentage of ACK erasures, measured error rates on the reverse link control channel, reverse link data channel error rates, and other methods. Upon determination of channel degradation, the access point can decide whether to ignore messages sent from the access terminal to instruct the access terminal to cease transmission.

摘要： Techniques for relaying a broadcast transmission in a wireless network are described. In one design, a relay may receive at least one transmission of a packet from a transmitter (e.g., a broadcast station) and may process the at least one transmission to decode the packet. The relay may generate at least one remaining transmission of the packet after correctly decoding the packet. The transmitter may broadcast multiple transmissions of the packet to receivers. The at least one transmission may be at least one of the multiple transmissions, and the at least one remaining transmission may be remaining ones of the multiple transmissions. The relay may send the at least one remaining transmission of the packet at the same time and on the same resources used by the transmitter. The multiple transmissions may be HARQ transmissions containing different redundancy information for the packet.
