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 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： Techniques for efficiently multiplexing a reference signal and data on different sets of subcarriers in the same symbol period are described. In one design, a user equipment (UE) performs a discrete Fourier transform (DFT) on a set of modulation symbols for data to obtain data symbols. The UE also obtains reference symbols generated based on a reference signal sequence corresponding to a cyclic shift of a base sequence. The UE maps the reference symbols to a first set of subcarriers and maps the data symbols to a second set of subcarriers. The UE then generates a transmission symbol based on the mapped reference symbols and the mapped data symbols. The UE may also transmit reference signals and data (i) in multiple symbol periods of a slot or a subframe and/or (ii) from multiple antennas using frequency division multiplexing (FDM) or code division multiplexing (CDM).

摘要： Techniques for synchronizing devices in a wireless network are described. In an aspect, a device determines a receive time for a base station, obtains a time offset for the base station from a network entity, and sets its transmit time based on the receive time and the time offset for the base station. The time offset compensates for the degree by which the base station is asynchronous with respect to a reference time, e.g., UTC time. In another aspect, a device determines and sends time difference information (e.g., a time offset or a TDOA measurement) for at least one base station to support synchronization of other devices. In yet another aspect, a network entity supports synchronization of devices, receives time difference information for at least one base station, and determines at least one time offset for the at least one base station based on the time difference information.

摘要： In embodiments, a wireless receiver employs a hardware-based Fast Fourier Transform (FFT) engine controlled by firmware. The FFT engine executes tasks stored in a task list. Each task is associated with a different portion of a signal, for example, one or more Orthogonal Frequency Division Modulated (OFDM) symbols. Each task may include configuration information for the FFT engine for configuring the engine to process the associated portion of the signal, a pointer to the portion to be processed, and another pointer to the memory for storing the output. The task list may be firmware controlled. Division of the FFT into a configurable hardware part driven by firmware to read and execute the tasks in the task list may speed up the FFT process and make it more flexible. A hardware beacon sorter may be coupled to the FFT engine to sort the sub-carriers according to their energies.

摘要： Techniques for managing interference in a wireless communication system are disclosed. In one aspect, an estimated interference associated with data transmission over a plurality of subcarriers on an uplink is determined. The estimated interference may relate to intermodulation products associated with a parallel transmission over the plurality of subcarriers. Based at least partly on the estimated interference, data received on the downlink can be processed, and subcarriers can be selected for data transmission on the uplink. Additionally, resources can be assigned to a wireless device according to the estimated interference.

摘要： Techniques for supporting communication for wireless devices in a wireless network are described. The wireless network may support a first physical channel having a first minimum SNR for reliable reception. Some wireless devices may require operation at a lower SNR. In an aspect, low SNR operation may be supported by transmitting data on a second physical channel that can be reliably received at a second minimum SNR that is lower than the first minimum SNR. In another aspect, low SNR operation may be supported by transmitting data on both the first and second physical channels. In yet another aspect, low SNR operation may be supported by transmitting data in multiple instances of the first and/or second physical channel. In yet another aspect, low power operation may be supported by transmitting the second physical channel in a portion of the system bandwidth instead of across the entire system bandwidth.

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： Systems and methodologies are described that facilitate improved resource partitioning and interference management in a wireless communication system. Techniques are described herein for the transmission and use of various types of signaling, such as Access Request commands, Reverse Link Special Resource Utilization Message (R-SRUM) signaling, Forward Link Special Resource Utilization Message (F-SRUM) signaling, and the like, for managing interference associated with range extension, restricted association networks, and other jamming scenarios. As described herein, downlink resource coordination and interference management are accomplished through the use of Access Request or R-SRUM signaling conducted in a unicast or broadcast fashion, and uplink resource coordination and interference management are accomplished through the use of F-SRUM signaling. As further described herein, a clean communication channel such as a Low Reuse Preamble (LRP) channel can be utilized for interference management signaling and/or leveraged for determining timing of various signaling messages.

摘要： Systems and methodologies are described that facilitate transmitting control information in wireless networks. Portions of bandwidth can be blanked for transmitting control information, and the control information transmitters can utilize beacon symbols to convey the control information. In this regard, interference is mitigated with respect to data transmissions over the control information bandwidth. Selected frequencies of the beacon symbols in a codeword can be used to indicate the control information. The codewords can be encoded with an error control code to provide redundancy for decoding in the presence of some interference.
