摘要： Techniques for supporting peer-to-peer (P2P) communication are disclosed. In an aspect, P2P communication may be supported with a symmetric waveform for a P2P downlink and a P2P uplink. In one design, a first UE generates a first signal based on a particular waveform (e.g., a downlink waveform or an uplink waveform for a wireless network) and transmits the first signal to a second UE for P2P communication. The first UE also receives a second signal generated by the second UE based on the particular waveform and transmitted to the first UE for P2P communication. In another aspect, a proximity detection signal may be transmitted in a portion of a subframe instead of the entire subframe. The remaining portion of the subframe may be used to transmit control information and/or other information to support P2P communication.
摘要翻译：披露了用于支持点对点（P2P）通信的技术。在一方面，P2P通信可以以P2P下行链路和P2P上行链路的对称波形来支持。在一种设计中，第一UE基于特定波形（例如，下行链路波形或无线网络的上行链路波形）生成第一信号，并将第一信号发送到第二UE进行P2P通信。第一UE还基于特定波形接收由第二UE生成的第二信号，并发送给第一UE进行P2P通信。另一方面，可以在子帧的一部分而不是整个子帧中发送接近检测信号。子帧的剩余部分可以用于发送控制信息和/或其他信息以支持P2P通信。

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 centralized control of peer-to-peer (P2P) communication and centralized control of femto cell operation are described. For centralized control of P2P communication, a designated network entity (e.g., a base station) may control P2P communication of stations (e.g., UEs) located within its coverage area. The designated network entity may receive an indication of a first station (e.g., a UE) desiring to communicate with a second station (e.g., another UE). The designated network entity may determine whether or not to select peer-to-peer communication for the first and second stations, e.g., based on the quality of their communication link. The designated network entity may assign resources to the stations if peer-to-peer communication is selected. For centralized control of femto cell operation, the designated network entity may control the operation of femto cells (e.g., may activate or deactivate femto cells) within its coverage area.

摘要： Techniques for centralized control of peer discovery pilot transmission are described. In an aspect, a designated network entity (e.g., a base station or a network controller) may control transmission of peer discovery pilots by stations located within its coverage area. In one design, the network entity may receive signaling triggering peer discovery pilot transmission. The network entity may direct each of at least one station to transmit a peer discovery pilot to allow one or more stations to detect the at least one station. The peer discovery pilot may include at least one synchronization signal or at least one reference signal. The network entity may receive pilot measurements from the one or more stations for peer discovery pilots from peer stations and/or reference signals from base stations. The network entity may determine whether or not to select peer-to-peer communication for two stations based on the pilot measurements.

摘要： Techniques for supporting operation of relay stations in wireless communication systems are described. In an aspect, a base station may transmit data to a relay station in a portion of a subframe instead of the entire subframe. The relay station may transmit control information during part of the subframe. The base station may transmit data to the relay station during the remaining part of the subframe. In another aspect, a target termination for a packet may be selected based on data and/or ACK transmission opportunities available for the packet. One or more transmissions of the packet may be sent with HARQ, and ACK information may be sent for the packet. The packet may be transmitted such that it can be terminated prior to the first subframe (i) not available for sending the packet or (ii) available for sending ACK information.

摘要： Systems and methodologies are described that facilitate indicating a dominant interferer to a target serving base station in a wireless communication environment. A mobile device can detect presence or absence of a dominant interferer. Further, an access probe that includes information related to the presence or absence of the dominant interferer can be generated. For example, the information can be included in a payload of the access probe as an explicit flag, an explicit indication of an interference level, a Channel Quality Indicator (CQI) value (e.g., reserved versus non-reserved, . . . ), etc. Moreover, the access probe can be transmitted to the target serving base station to initiate an access procedure. The target serving base station can select a time-frequency resource to be utilized for a responsive downlink transmission (e.g. access grant signal, subsequent access related message, . . . ) as a function of the information included in the access probe.

摘要： Techniques for supporting data transmission via a relay station are described. In an aspect, data transmission may be supported using ACK-and-suspend. A transmitter station sends a first transmission of a packet to a receiver station. The transmitter station receives no ACK information for the first transmission of the packet and suspends transmission of the packet. The transmitter station thereafter receives an indication to resume transmission of the packet and, in response, sends a second transmission of the packet. In another aspect, different ACK timeline may be used when applicable. The receiver station may send ACK information in a designated subframe if available for use or in a different subframe. In yet another aspect, ACK repetition may be used. The receiver may send ACK information in multiple subframes to facilitate reception of the ACK information when the transmitter station is unable to receive one or more of the multiple subframes.
