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 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： 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： Systems and methodologies are described that facilitate dynamically forming clusters in a wireless communication environment. A set of non-overlapping clusters can be formed dynamically over time and in a distributed manner. Each of the clusters can include a set of base stations and a set of mobile devices. The clusters can be yielded based upon a set of local strategies selected by base stations across the network converged upon through message passing. For example, each base station can select a particular local strategy as a function of time based upon network-wide utility estimates respectively conditioned upon implementation of the particular local strategy and disparate possible local strategies that can cover the corresponding base station. Moreover, operation within each of the clusters can be coordinated.

摘要： Techniques for transmitting signaling with localized spreading are described. In one design, a transmitter (e.g., a base station) spreads multiple signaling symbols to obtain multiple sets of output symbols and further maps the multiple sets of output symbols to multiple time frequency blocks. The spreading may be localized to each time frequency block. Prior to the spreading, the transmitter may scale the multiple signaling symbols with multiple gains determined based on the transmit power for these signaling symbols. The transmitter may scramble the scaled signaling symbols to obtain scrambled symbols and may spread the scrambled symbols to obtain the multiple sets of output symbols. The transmitter may map each set of output symbols to a respective time frequency block.
