摘要： Various embodiments relate to using available spectrum for peer to peer communications and for selecting which of several possibly available channels should be used. Various methods and apparatus are well suited to peer to peer networks in which channel usage decisions are made in a decentralized manner. A wireless terminal generates a list of potential available channels to be used for peer to peer communications, e.g., based on FCC information and/or local sensing. Channels are filled in accordance with a predetermined channel ordering. A wireless terminal migrates between the channels in accordance with changes in the number of peer devices using a channel. The network, in a distributed manner, changes the number of channels in use at a location in response to changes in numbers of active peer devices at a location.

摘要： Methods and apparatus for determining a mode of wireless communications to be used by a wireless terminal, e.g., a direct communications mode or an infrastructure communications mode are described. In some embodiments, the mode to be used is determined by a control node based on interference which will be caused to the system taking into consideration at least an area, e.g., cell, in which the wireless terminal seeking to communicate is not located. System interference cost estimates for each mode under consideration are generated and compared. Interference cost estimates may, and do, correspond to different frequency bands when the direct mode uses a different frequency band than the infrastructure communications mode. Separate interference cost estimates and mode determinations are made for different communications directions in some embodiments. The determined mode to be used is communicated to the devices seeking to communicate, e.g., via one or more base stations.

摘要： Methods and apparatus related to detecting identifiers in a wireless communications system are described. Various methods and apparatus are well suited to a decentralized peer to peer wireless communications system in which devices monitor for and attempts to detect peer discovery identifiers of interest. Identifiers correspond to identifier bit sequences which are intentionally structured to appear to be random sequences. A portion of an identifier bit sequence is broadcast in a peer discovery interval. A receiver device, searching for a particular bit sequence of interest, tries to match received peer discovery bit sequence portion against a corresponding portion of the bit sequence of interest. Matching bits are determined on a per portion basis, and an updated match quality value is determined. A match or mismatch condition is determined as a function of the updated match quality value.

摘要： Aspects describe enabling two peers that have already paired together under some circumstances to re-identify themselves under different circumstances so that the peers can bypass performing another pairing only to discover that they are already paired. A Bloom filter is constructed from an available pool of locally selected identifiers and is sent to a peer node in a first message. Upon receiving the message with the Bloom filter, peer node checks all its known identifiers. If peer node finds that one of its identifiers is a member of the Bloom filter, peer node sends a reply in order to achieve a mutual identification.

摘要： Aspects relate to interference management in a multiple-input-multiple-output peer-to-peer network utilizing connection scheduling. When channel side information is available at both transmitter and receiver, both devices determine transmit/receiver beamforming vectors. Transmitter sends a first transmission request signal with first transmit beamforming vector and a second transmission request signal with second transmit beamforming vector in a transmission request block. Receiver estimates SINRs of the MIMO channels associated with the receive beamforming vectors and determines whether to return request response signals. Based on received request response signals, transmitter decides to transmit streams of data using the corresponding transmit beamforming vectors in the data burst. When channel side information is available only at receiver, transmitter sends one transmission request signal. Receiver estimates the SINRs of the MIMO channels associated with receive beamforming vectors using MMSE and/or successive interference cancellation (SIC), and returns request response signals in the request response block.
摘要翻译：方面涉及利用连接调度的多输入多输出对等网络中的干扰管理。当信道侧信息在发射机和接收机都可用时，两个设备确定发射/接收机波束成形向量。发射机在发射请求块中发送具有第一发射波束形成向量的第一传输请求信号和具有第二发射波束形成向量的第二传输请求信号。接收机估计与接收波束成形向量相关联的MIMO信道的SINR，并确定是否返回请求响应信号。基于接收到的请求响应信号，发射机决定使用数据突发中的对应的发射波束形成向量来发送数据流。当信道侧信息仅在接收机可用时，发射机发送一个传输请求信号。接收机使用MMSE和/或连续干扰消除（SIC）估计与接收波束成形向量相关联的MIMO信道的SINR，并且在请求响应块中返回请求响应信号。

摘要： Methods and apparatus well suited for supporting communications over different ranges in, for example, a peer to peer wireless communications system, are described. In the peer to peer network at least some of the types of signals, e.g., peer discovery signals and/or paging signals, are transmitted with no closed loop power control. An exemplary peer to peer timing structure includes air link resources allocated for a particular type of signaling in which the resources are segmented into multiple blocks which do not overlap in time, different ones of the multiple blocks being associated with different ranges. The characteristics of the basic transmission units of the multiple blocks based on range are different, e.g., tone size and symbol width are different. A wireless communications device implements the peer to peer timing structure and uses resources from different range based blocks at different times. Data traffic transmission units may be the same regardless of the range.

摘要： Providing for secure tracking and reporting of wireless resources utilized by a mobile device is described herein. By way of example, resources utilized in conjunction with network- facilitated or peer-to-peer wireless data exchange can be tracked in secure, tamper-resistant components of the mobile device. Further, a report can be compiled from the tracked information and digitally signed with a secret data/material specific to the mobile device. The signed report can be submitted to a network server in conjunction with accounting, billing or like functions. By validating the signature of a mobile device, the network server can trust that information collected and submitted by user devices has not been tampered with or spoofed with an ID of another such device.

摘要： Techniques for performing automatic gain control (AGC) at a terminal in a wireless communication network are described. In an aspect, the terminal may use different receiver gain settings to receive different types of signals in different time intervals. The terminal may determine a receiver gain setting for each signal type and may use the receiver gain setting to receive signals of that signal type. In another aspect, the terminal may determine a receiver gain setting for a future time interval based on received power levels for peer terminals expected to transmit in that time interval. The terminal may measure received power levels of signals received from a plurality of terminals. The terminal may determine a set of terminals expected to transmit in the future time interval and may determine the receiver gain setting for the future time interval based on the measured received power levels for the set of terminals.
