摘要： A decentralized approach to peer discovery channel selection is used in some embodiments. In some such embodiments, a mobile wireless terminal supporting a peer to peer signaling protocol, independently determines what channels to use for peer discovery without a central controller indicating the channel or channels to be used. Assuming channels are of a suitable quality, the channels having the best quality need not be identified, with channel selection being made on a predetermined channel ordering basis from those with suitable quality. Different wireless communications devices in the system use the same peer discovery channel selection process making it likely that the same channel or channels will tend to be picked to be used for peer discovery. Other embodiments are directed to implementing a centralized approach to peer discovery channel selection in which a central controller or base station selects channels to be used for peer discovery signaling.

摘要： Methods and apparatus related to control channels in a wireless communications system are described. Different white space bands may be available at different locations. A wireless terminal monitors control information from multiple potentially available communications channels. Control time slots corresponding to some different channels are intentionally time offset from one another. Some embodiments implement predetermined control slot timing synchronized with respect to an external timing source. In other embodiments, a wireless terminal selects a control time slot on a new channel as a function of control slot timing on channels already in use. A wireless terminal selects one of a plurality of communications channels for use in communicating information and determines a position of a control time slot to be used on the selected communications channels. The wireless terminal uses the control time slot on the selected communications channel to transmit and receive control information.

摘要： Methods and apparatus related to selecting and/or using different coding methods for a broadcast channel are described. The coding method to be used is selected as a function of an estimated level of congestion. Various methods and apparatus are well suited for use in peer to peer wireless communications systems including broadcast peer discovery channels. A wireless communications device, e.g., a mobile terminal supporting peer to peer signaling, detects peer discovery signals from other devices and estimates a level of congestion. The wireless communications device selects one of a plurality of alternative coding methods as a function of the estimated level of congestion. Two different coding methods which may be used, in some embodiments, vary in at least one of: coding rate, convolution code used, and amount of resources used. The wireless device transmits information indicating the selected coding method and coded peer discovery data in accordance with the selected coding method.

摘要： Various methods and apparatus relate to sharing QoS privileges between devices having a higher service level subscription and devices having lower service level subscription. QoS privileges are associated with a QoS service level which is in turn tied to devices, e.g., based on a service level subscription of the device. Devices with higher service level subscription are entitled to superior QoS privileges than the devices with lower service level subscription. In various embodiments a first device with higher QoS service level provides, to a second device having lower QoS service level, information used to obtain a QoS privilege to which the first device is entitled. Thus the second device entitled to lower QoS privileges is provided with the superior QoS privileges on a limited basis, e.g., for communicating with the first device corresponding to the higher QoS service level.
摘要翻译： 各种方法和装置涉及在具有较高服务级别订阅的设备和具有较低服务级别订阅的设备之间共享QoS特权。 QoS权限与QoS服务级别相关联，QoS服务级别又依赖于设备，例如基于设备的服务级别订阅。 具有较高服务级别订阅的设备有权享受比具有较低服务级别订阅的设备更高的QoS权限。 在各种实施例中，具有较高QoS服务级别的第一设备向具有较低QoS服务级别的第二设备提供用于获得第一设备所授权的QoS特权的信息。 因此，有权降低QoS特权的第二设备在有限的基础上被提供有优越的QoS权限，例如用于与对应于较高QoS服务级别的第一设备进行通信。
