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： Systems and methodologies are described that facilitate cooperation strategy selection for a network multiple-in-multiple-out (N-MIMO) communication system. As described herein, one or more nodes in a communication system capable of N-MIMO communication can calculate marginal utilities, projected per-user rates, and/or other parameters corresponding to respective associated users. Based on these calculations, respective network nodes can perform user scheduling and selection, cell scheduling and selection, selection of a cooperation strategy (e.g., coordinated silencing, joint transmission, coordinated beamforming, etc.), and/or other operations to provide cooperative communication for respective users. As further described herein, projected rate calculation for a given user can be adjusted based on processing or channel implementation loss associated with the user, interference nulling capability of the user, or other factors. As additionally described herein, these and/or other parameters can be fed back by respective users to a serving network node and/or mandated via system performance requirements.

摘要： Techniques for sending hierarchical feedback of channel state information are described. In one design, a user equipment (UE) determines channel gain information for multiple cells selectable to transmit data to the UE. The UE also determines intra-cell relative phase information for at least one cell among the multiple cells. The UE reports the channel gain information and the intra-cell relative phase information. The channel gain information may include multiple quantized channel vectors for each of the multiple cells. The intra-cell relative phase information may indicate phase errors in the quantized channel vectors for each of the at least one cell. The UE may also determine and report other information. The UE may receive data from one or more cells among the plurality of cells. Each cell may transmit data based on at least one transmit vector determined based on the channel gain information and the intra-cell relative phase information.

摘要： Providing for a multipoint equalization (MPE) framework for coordinated multipoint (CoMP) transmission in wireless communication is described herein. The disclosed MPE framework involves distributed scheduling decisions for CoMP transmission, reducing complexity of scheduling coordination as compared with centralized scheduling techniques that coordinate scheduling decisions for multiple network base stations. Further, the MPE framework involves distributed computation of CoMP transmission coefficients, relying on a maximum of two backhaul hops to obtain information for the computation, and disseminate the transmission coefficients. The disclosed MPE framework shows substantial gains in various network deployments over conventional CoMP techniques.

摘要： Techniques are provided for accessing a shared radio frequency spectrum band by selecting a subset of antennas associated with a successful access procedure for accessing the shared radio frequency spectrum. In some examples, a wireless communication device, such as a network node, may perform a listen before talk (LBT) procedure for each of two or more subsets of antennas associated with the network node, and only those subsets of antennas that pass the LBT procedure are used for transmissions during the associated time period, while other antennas are idle, or used for transmissions on another radio frequency spectrum band during the associated time period. In some examples, antennas of a wireless communication device may perform an access procedure utilizing beamforming capabilities of associated antennas to determine one or more different spatial directions that may provide access to the shared radio frequency spectrum band.
