摘要： A base station receives loading information indicative of the loading of other base stations and determines a downlink transmission power budget as a function of the received loading factor information. The base station may decrease/increase a current power budget dedicated to downlink traffic channel segments in response to detecting an increase/decrease in loading at an adjacent base station. Thus, base stations operate in a cooperative manner reducing power output, in at least some cases, where loading at a neighboring base station increases thereby reducing the interference to the base station with the increased load. A base station can consider possible alternative transmission power levels, estimated levels of interference, and/or possible alternative data rates in making trade-off decisions regarding downlink power budget.

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： 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 relating to interference mitigation in a wireless communications system including multi-sector base stations and relay stations are described. Different types of transmission slots are used, e.g., base station-relay station slots, relay station-access terminal slots, and base station-access terminal slots. Relay station to access terminal slots of a first schedule are non-overlapping with relay station to access terminal slots of a second schedule. A deployment pattern associates each particular base station sector and its associated relay station with one particular schedule. At least some different sectors of the same base station intentionally use different schedules. An access terminal determines and uses the schedule corresponding to the base station sector or relay station from which it intends to receive downlink signals. By utilizing multiple slot type allocation schedules and a particular schedule deployment pattern in the system, interference experienced by access terminals in boundary regions can be mitigated.

摘要： A peer to peer communications system implements scheduling of traffic intervals in a distributed manner utilizing connection priority and interference information. A peer to peer timing structure includes a user scheduling interval, with ordered transmission request and response intervals, and an associated traffic interval. The priority associated with a request of an early interval is higher than the priority of a request of a later interval. A first device, connected to a second device, makes a decision as to whether or not to yield the traffic interval as a function of estimated interference that it will impose on higher priority connection receivers if it transmits during the traffic interval. The second device makes a decision as to whether or not to transmit a positive transmission request response signal as a function of a generated received signal quality value, based on received requests for its own and for higher priority connections

摘要： Methods and apparatus related to peer to peer communication networks are described. A peer to peer traffic transmission request is linked to a subsequent traffic transmission interval having a fixed relationship to the transmitted transmission request. In various embodiments, when a first peer to peer device, which has requested a second device for authorization to use a linked subsequent traffic transmission interval, has been granted its request and has decided to transmit traffic during the subsequent traffic interval, the first device transmits a peer to peer pilot and receives a rate information signal, prior to transmitting the traffic signal. In some embodiments, the transmitted pilot signal and the received rate information signal are communicated using corresponding air link resources associated with the traffic interval.

摘要： Methods and apparatus are described for improved utilization of air link resources. A base station includes at least one of a plurality of receive antenna elements and a plurality of transmit antenna elements for communicating with a wireless terminal. The base station generates channel estimation vectors corresponding to wireless terminals using the base station, where a generated channel estimation vector includes different elements corresponding to different base station antenna elements. The base station determines a level of orthogonality between pairs of channel estimation vectors corresponding to different wireless terminals. At least some of the segments to be assigned by the base station are substantially overlapping, e.g., the segments overlap fully or to a high degree. Wireless terminal pairs which have substantially orthogonal channel estimation vectors are matched and assigned to substantially overlapping segments, and the power level associated with the segments is controlled to be substantially the same.
