摘要： Systems and methodologies are described that facilitate power headroom management in a wireless communication system. As described herein, a predefined relationship between locations along a system frequency band and corresponding power backoff parameters is utilized to minimize spurious emissions outside the system frequency band and/or excessive interference by, for example, associating locations near one or more edges of the permitted frequency band with substantially high power backoff parameters. As further described herein, the predefined relationship can be known a priori to the base station and the mobile terminal.

摘要： Systems and methodologies are described that facilitate providing high reuse for transmitting reference signals, such as positioning reference signals (PRS) and cell-specific reference signals (CRS), to improve hearability thereof for applications such as trilateration and/or the like. In particular, PRSs can be transmitted in designated or selected positioning subframes. Resource elements within the positioning subframe can be selected for transmitting the PRSs and can avoid conflict with designated control regions, resource elements used for transmitting cell-specific reference signals, and/or the like. Resource elements for transmitting PRSs can be selected according to a planned or pseudo-random reuse scheme. In addition, a transmit diversity scheme can be applied to the PRSs to minimize impact of introducing the PRSs to legacy devices. Moreover, portions of a subframe not designated for PRS transmission can be utilized for user plane data transmission.

摘要： Method and apparatus for estimating reverse link loading in a wireless communication system. The reverse link interference is measured and reverse link receiver noise is measured. The reverse link interference is compared to the reverse link receiver noise, for example, by dividing the interference power by the receiver noise power. The reverse link receiver noise can be measured in an orthogonal frequency division multiple access (OFDMA) system by nulling transmission from access terminals within the cell and nearby during a null time and frequency interval. Power measure in the null time and frequency interval is receiver noise power. The reverse link interference can be measure by several means. For example, local null time and frequency intervals can be designated. The access terminals within the cell null their transmissions during the local time and frequency intervals. Access terminals outside the cell continue to transmit during the local time and frequency intervals. Power measured in the local time and frequency interval is interference power. As another example, interference power can be measured by subtracting pairs of pilot symbols that are contiguous to each other in time or frequency.

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： 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.
