摘要： Techniques for performing peer discovery in a wireless network are described. A device may perform peer discovery to detect and identify other devices of interest. In an aspect, the device may perform peer discovery based on a hybrid mode that includes autonomous peer discovery and network-assisted peer discovery. In another aspect, the device may perform peer discovery based on a push mode and a pull mode. For the push mode, the device may occasionally transmit and/or receive a peer detection signal. For the pull mode, the device may transmit and/or receive a peer discovery request when triggered. In yet another aspect, the device may perform event-triggered peer discovery (e.g., for the pull mode). In yet another aspect, the device may perform peer discovery using both a downlink spectrum and an uplink spectrum. In yet another aspect, the device may transmit a peer detection signal in a manner to improve detection and/or increase payload.

摘要： Techniques for establishing and maintaining peer-to-peer (P2P) communication are described. In an aspect, P2P communication on an unlicensed spectrum may be established and maintained with network assistance. In one design, a user equipment (UE) may communicate with a wide area network (WAN) to establish P2P communication with at least one other UE on a first frequency band that is not licensed to the WAN. For example, the UE may receive an assignment of at least one frequency channel in the first frequency band for P2P communication. The UE may then communicate peer-to-peer with the other UE(s) on the at least one frequency channel. The UE may also communicate with the WAN to maintain P2P communication with the other UE(s), e.g., to switch to another frequency channel if necessary.

摘要： Techniques for performing peer discovery to enable peer-to-peer (P2P) communication are disclosed. In an aspect, a proximity detection signal used for peer discovery may be generated based on one or more physical channels and/or signals used in a wireless network. In one design, a user equipment (UE) may generate a proximity detection signal occupying at least one resource block based on a SC-FDMA modulation technique. In another design, the UE may generate a proximity detection signal occupying at least one resource block based on an OFDMA modulation technique. The UE may generate SC-FDMA symbols or OFDMA symbols in different manners for different physical channels. In yet another design, the UE may generate a proximity detection signal including a primary synchronization signal and a secondary synchronization signal. For all designs, the UE may transmit the proximity detection signal to indicate its presence and to enable other UEs to detect the UE.

摘要： Techniques for supporting data transmission on the uplink in a wireless network are described. In an aspect, a user equipment (UE) may send a data transmission to a serving base station and may send uplink control information (UCI) to a non-serving base station. The UCI may include pertinent information to allow the non-serving base station to process the data transmission from the UE. In one design, the UCI may allow the non-serving base station to estimate the interference due to the data transmission from the UE and to cancel the interference at the non-serving base station. The interference cancellation may improve the received signal quality at the non-serving base station. After the interference cancellation, the non-serving base station may process a data transmission from another UE served by the base station.

摘要： Techniques for transmitting data with persistent interference mitigation in a wireless communication system are described. A station (e.g., a base station or a terminal) may observe high interference and may send a request to reduce interference to interfering stations. The request may be valid for a time period covering multiple response periods. Each interfering station may grant or dismiss the request in each response period, may dismiss the request by transmitting at full power, and may grant the request by transmitting at lower than full power. The station may receive a response from each interfering station indicating grant or dismissal of the request by that interfering station in each response period. The station may estimate SINR based on the response received from each interfering station and may exchange data with another station based on the estimated SINR. Persistent interference mitigation may reduce signaling overhead and improve resource utilization and performance.

摘要： Providing for management of wireless communications in a heterogeneous wireless access point (AP) environment is described herein. By way of example, system data of an over-the-air message can be configured to include information identifying a distinct type of transmitting base station. In some aspects, the information can include an access type of the base station and/or a sector ID for distinguishing the base station among large numbers of other base stations. According to other aspects, the information can include wireless channel resources designated for a particular type of base station, or blanked by the transmitting base station, to facilitate interference reduction on such resources. By employing aspects of wireless communication management disclosed herein, efficient and reliable communication can be affected in large heterogeneous AP networks.
