摘要： A communications device synchronizes itself with respect to an external reference signal, e.g., a GPS signal. The communications device detects timing reference signals, e.g., beacon signals, from a communications network. If the communications device determines that the network is not synchronized to the external timing reference signal, the communications device operates as a master timing control device. In various embodiments, when operating as a master timing control device the wireless communications device communicates time stamps, e.g., in beacon signals, which indicate a greater passage of time than the actual passage of time. When operating as a master timing control device the communications device transmits network timing reference signals at a higher rate than is being used by the network to seize control of network timing and become the master timing control device. The communications device drives the network timing to synchronize network timing to the external timing reference.

摘要： Methods and apparatus are described which increase the probability and/or frequency that devices with comparatively faster clocks in a network than other devices in the network will transmit beacon signals are described. As a result, devices with faster clocks will tend to drive system synchronization to convergence faster than if all devices transmitted beacons at the same rate, thus facilitating more reliable maintenance of system synchronization since the devices with faster clocks will tend to transmit more frequently.

摘要： Methods and apparatus related to the communication of traffic in peer to peer communications are described. A peer to peer communications system includes traffic slots, and for a pair of devices (first and second) having a connection a first transmission request resource and a second transmission request resource are associated with a traffic transmission interval of the traffic slot, the first request resource preceding the second request resource. The first device can utilize the first resource to transmit a request to transmit traffic to the second device, and when it does, it also uses the second resource to transmit additional information corresponding to the request and/or traffic. If the second device doesn't detect a request on the first resource, then it can use the second resource to transmit a request to first device to transmit traffic to the first device.

摘要： A transmission initiation interval timing structure is used in combination with a lower layer timing structure, e.g., physical layer timing structure. A device selects a subset of packet transmission initiation intervals and then limits initiation of packet transmission to those intervals thereby reducing the potential for collisions. Packet transmission may occur outside the initiation interval in which the transmission is initiated. In some embodiments, packet transmission length is intentionally limited to sizes which can be transmitted in a fraction of the amount of time the physical layer allows a single device to continuously transmit, e.g., in an amount of time which is equal to or less than the duration of a packet transmission initiation interval. This increases the probability that multiple devices will be able to successfully transmit small packets at short intervals on a regular basis even when carrier sensing techniques are used.
摘要翻译：传输启动间隔定时结构与较低层定时结构结合使用，例如物理层定时结构。设备选择分组传输启动间隔的子集，然后限制分组传输的开始到那些间隔，从而减少冲突的可能性。分组传输可能发生在传输启动的发起间隔之外。在一些实施例中，分组传输长度被有意地限制为可以在物理层允许单个设备连续发送的时间量的一小部分中传输的大小，例如，等于或小于分组传输启动间隔的持续时间。这增加了即使在使用载波感测技术的情况下，多个设备将能够以短时间间隔成功地发送小分组的概率。

摘要： A method of operating a wireless device is provided in which the wireless device determines to use one grouping of peer discovery resources of a plurality of groupings of peer discovery resources based on one of a path loss or a distance to a base station. The plurality of groupings include a first grouping of resources having a first plurality of identical subsets of resources and a second grouping of resources having a second plurality of identical subsets of resources. Each of the first plurality of identical subsets of resources extends over at least one of a different time period or a different number of subcarriers than each of the second plurality of identical subsets of resources. The wireless device transmits a peer discovery signal on one subset of the identical subsets of said one grouping of peer discovery resources.
