摘要： Techniques for transmitting signals using time hopping or time and frequency hopping are described. In one design, a terminal selects different slots to use for transmission in multiple frames with time hopping. Each frame includes multiple slots, and each slot covers a particular time duration. The selected slots are at different time locations in the multiple frames. In another design, a terminal selects different resource units to use for transmission in multiple frames with time and frequency hopping. The selected resource units are at different time and frequency locations in the multiple frames. For both designs, the terminal sends a signal (e.g., a peer discovery signal) in the selected slots or resource units in the multiple frames. The terminal may detect for signals (e.g., peer discovery signals) from other terminals in slots not used for transmission by the terminal.

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： Aspects describe different multiple antenna techniques that can be utilized in a peer-to-peer network based on a network congestion level. A MIMO scheme where a transmitter sends to a receiver multiple spatial streams at substantially the same time in the same traffic segment can be utilized when network congestion level is low. A receiver beam forming scheme where transmitter sends a single stream in a traffic segment and receiver uses multiple receive antennas to maximize signal to noise ratio can be utilized when network congestion level is high. The connection pair (transmitter and receiver) occupy more control resources in the MIMO scheme than the receiver beam forming scheme. The decision related to which technique to utilize can be made at about the same time as a communication is initiated. Further, if network conditions change during a communication, the antenna technique that is utilized can be switched to a different technique during the communication exchange.

摘要： Aspects relate to mitigating interference in a communication network that does not employ a centralized scheduler. A transmission sent on a subset of resources is evaluated to determine a number of communication pairs that have selected that subset of resources on which to transmit. If there are a large number of communication pairs transmitting on that subset, the transmission is ignored by a receiving device. The number of degrees of freedom that contain energy on the subset is evaluated to determine if an expected number of degrees of freedom that should have energy is met or exceeded. If the expected threshold number is met or exceed, the transmission is decoded by the receiving device, else the transmission is not decoded.

摘要： Non-coherent modulation is used to communicate coding information via pilot signals using a first subset of resources, and coherent modulation is used to generate data signals. This allows for a stronger global code while keeping individual signaling complexity low. First and second communications devices communicate information using a set of communications resources. By performing non-coherent demodulation on pilot signals received on a first subset of said set of communications resources coding information is recovered. First and second channel estimates are generated from the pilot signals received on the first subset of said communications resources. Coherent demodulation is performed on data signals received on a second subset of said set of communications resources using said first and second channel estimates and said coding information to recover information communicated by said first communications device and to recover separate information communicated by said second communications device.

摘要： Methods and apparatus relating to scheduling of air link resources, e.g., traffic segments, in wireless communications are described. Various described methods and apparatus are well suited to wireless peer to peer networks in which traffic scheduling is decentralized, e.g. an ad hoc peer to peer network. A first wireless terminal receives a transmission request and quality of service information from a second wireless terminal corresponding to a connection. The first wireless terminal decides not to receiver yield, determines a request response transmission power level as a function of the received quality of service information, and transmits, at the determined power level, a generated request response signal. By controllably adjusting the transmission power level of a request response, transmitter yielding decisions of lower priority links are impacted, since lower priority links measure and use received power level information corresponding to request responses of higher priority links in their transmitter yielding decisions.

摘要： Methods and apparatus for supporting multiple modes of communication operation, e.g., with different parameters and/or frequency bands being used in the different modes of operation are described. One or more adjustments are made based on a signal or signals received in a first frequency band from a second communications device, e.g., an access router with reliable timing. The communications device selects between and operates in either the first frequency band, e.g., a WAN frequency band, or in a second frequency band, e.g., a LAN frequency band. The WAN and LAN frequency bands may be non-overlapping. One or more parameters used in the second frequency band have a predetermined relationship to one or more parameters used for communications in the first frequency band making the adjustment based on the signal received in the first frequency band relevant and useful to support communications in the second frequency band.
