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： Various methods and apparatus relate to controlling access to communications resources in a wireless communications system. Various described methods and apparatus are well suited for use in a peer to peer network in which resource access control is implemented in a distributed manner and wireless terminals compete for communications resources, e.g., compete for a peer to peer traffic segment. A wireless terminal generates QoS tokens within said wireless terminal at a rate which is a function of a QoS level associated with the wireless terminal and uses a generated token to control access to a communications resource. Generated tokens within the wireless terminal may be shared among the applications of the wireless terminal.

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： A wireless communications device supports a constant transmission power mode of operation and a time varying transmission power mode of operation for transmitting data, e.g., peer discovery data. The device determines an amount of network congestion and switches between the two modes of operation as a function of the determined amount of network congestion. Various described methods and apparatus are well suited for use in a peer to peer ad hoc wireless communications system in which a limited amount of air link resources are available for peer discovery signaling and the same peer discovery resources are, at times, used concurrently by multiple devices. When network congestion is low, the device operates in the constant transmission power mode. When network congestion is high, the device operates in the time varying power mode. Devices sharing a common peer discovery resource in a local area intentionally select different time varying transmission patterns.

摘要： Methods and apparatus for allocating traffic contention resource units in a wireless communications system in which decisions are made in a distributed manner are described. A wireless communications device, corresponding to a link, self allocates resource units for traffic contention. Decisions regarding initially acquiring resources, relinquishing acquired resources, and/or acquiring additional resources for traffic contention are based on detected levels of network congestion and/or detected changes in network congestion. A wireless communications device detects a level of network congestion and determines a number of resource units to acquire for traffic contention based on the detected level of network congestion.
