摘要： Techniques for supporting peer-to-peer (P2P) communication and wide area network (WAN) communication are disclosed. In one aspect, P2P communication may be supported on an uplink spectrum. A user equipment (UE) may communicate (i) with a base station on both a downlink spectrum and an uplink spectrum for WAN communication and (ii) with another UE on only the uplink spectrum for P2P communication. In another aspect, P2P communication may be supported by time division multiplexing the downlink and uplink (or transmit and receive links) for two UEs. In yet another aspect, WAN communication and P2P communication may be time division multiplexed, so that both can be concurrently supported by a UE. In yet another aspect, transmission gaps may be provided between WAN transmissions and P2P transmissions in order to avoid interference between these transmissions.

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.

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.

摘要： Techniques for performing network-assisted peer discovery to enable peer-to-peer (P2P) communication are described. In one design, a device registers with a network entity (e.g., a directory agent) so that the presence of the device and possibly other information about the device can be made known to the network entity. The network entity collects similar information from other devices. The device sends a request to the network entity, e.g., during or after registration. The request includes information used to match the device with other devices, e.g., information about service(s) provided by the device and/or service(s) requested by the device. The directory agent matches requests received from all devices, determines a match between the device and at least one other device, and sends a notification to perform peer discovery. The device performs peer discovery in response to receiving the notification from the network entity.

摘要： In a cellular wireless communication system, peer-to-peer (P2P) links between mobile devices are implemented, and controlled using an aggregate utility metric for a group of P2P and cellular links. A mobile node participating in a P2P link, or an eNB, may periodically broadcast an activity level indicator indicating a resource-dependent activity level of the link. The node may control the activity level in response to utility metrics received from members of neighboring P2P links to maximize an aggregate utility of the link and the neighboring P2P links sharing at least a subset of resources of a common frequency spectrum. Formation or termination of P2P links may be controlled in response to comparing a calculated achievable utility value to a current utility value of a link, and taking action calculated to maximize the aggregate utility value.

摘要： Techniques for supporting communication in an asynchronous TDD wireless network are described. In an aspect, downlink transmissions and uplink transmissions may be sent on different carriers in an asynchronous TDD wireless network to mitigate interference. In one design, a station (e.g., a base station or a UE) may send a first transmission on a first carrier in a first time period and may receive a second transmission on a second carrier in a second time period. The station may only transmit, or only receive, or neither in each time period. In one design, allocation of carriers for the downlink and uplink may be performed when strong interference is detected, e.g., by a base station or a UE. When strong interference is not detected, the first and second carriers may each be used for both the downlink and uplink.

摘要： Systems and methods that designate a control attachment point(s) during transmission of data in a Coordinated Multipoint (CoMP) system. The control attachment point is represented by an anchor cell to address control signaling and represent a User Equipment's (UE) interaction with the wireless communication system from a perspective of control (e.g., supplying/sending grants to the UE, transmitting/receiving ACKS on the downlink/uplink to the UE, control information (CQI), and the like.) The cells can further engage in backhaul transfer of information therebetween, and dynamic switching/change of anchor point based on criteria such as control loading, channel quality, and the like can further be implemented.

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： A hierarchical cyclic redundancy check (CRC) is provided that enables CRC appending and detection. A message that includes a first message portion and a second message portion is transmitted to two or more receivers. The receivers are not aware of the first message portion. One of the receivers can be aware of the second message portion of the message. Each portion of the message can be encoded with a CRC in order to provide protection. The receiver that is aware of the second message portion is provided a higher level of cyclic redundancy check (CRC) protection than the receivers that are not aware of the second message portions.
