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： 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.

摘要： A protocol is provided that facilitates downlink concurrent peer-to-peer communications (within a time slot or traffic slot) between one device and many terminals as well as uplink concurrent peer-to-peer communications (within a time slot or traffic slot) between a plurality of terminals and one device. The concurrent peer-to-peer communications may take place within an ad hoc network of devices. To facilitate such operation, a time-frequency structure is provided within a control channel that allows the device and terminals to identify the peer-to-peer connections. This time-frequency structure also allows terminals to identify other sibling terminals that have a connection with the same device, thereby allowing to more efficiently performing interference mitigation. That is, sibling peer-to-peer connections with the same device may be treated different from other non-related peer-to-peer connects for purposes of interference mitigation in a wireless network.

摘要： Methods and apparatus related to group communications in a wireless communications system, e.g., a peer to peer wireless communications system, are described. Methods and apparatus directed to closed groups, e.g., where the number of group members are fixed at a given time and known to one or more members of the group, are described. Various embodiments are well suited to decentralized peer to peer wireless networks including a plurality of individual traffic resources, e.g., traffic slots and/or traffic segments, which may be independently scheduled in a decentralized manner. Some features and/or aspects are directed to the use of individual group member acknowledgement signaling in response to a transmitted group traffic data signal. By monitoring for anticipated individual group member acknowledgment signals and identifying members which have not signaled a positive acknowledgment, re-transmission can be directed and/or tailored to a subset of the group.

摘要： In an ad hoc peer-to-peer communication network between wireless devices, a high priory first receiver device is configured to perform successive interference cancellation. A first pilot signal is received by the first receiver device from the first transmitter device. Similarly, a second pilot signal is received from a second transmitter device, the second pilot signal indicating that the second transmitter device intends to transmit a second traffic signal. The first receiver device determines a first and a second transmission rates for traffic transmissions from the first transmitter device. A control message is then transmitted by the first receiver device to the first transmitter device including the first and second transmission rates. Subsequently, the first receiver device wirelessly receives a traffic signal including a first traffic signal from the first transmitter device including a first and a second signal components generated from a first and a second codewords, respectively.

摘要： A first device is configured to select and utilize a connection identifier (CID) for a peerto- peer communication connection between the first device and a second device in a wireless communications network. The CID is selected from a predetermined set of a plurality of CIDs. Prior to selecting the connection identifier, the first device monitors a CID broadcast channel to determine whether the CID is being utilized by other nearby connections. If it is determined that the CID is being utilized by another connection in the proximity, a different (unused) CID is selected. A transmission request is transmitted to the second device using a first transmission resource unit within a traffic management channel slot, the first transmission resource unit being determined as a function of the selected CID. The first device transmits traffic data to the second device in a traffic channel slot corresponding to the traffic management channel slot.

摘要： Apparatus and method are provided for generating transmission connection identifiers (CIDs) in a non-orthogonal or pseudo-random manner identifying peer-to-peer connections in a wireless communication network. When a transmitter terminal intends to transmit to its peer receiver terminal, it just picks a transmission CID in a pseudo-random manner, without trying to avoid a similar transmission CID in a neighborhood. The method of generating this pseudo-random transmission CID may be agreed to between the transmitter and its intended receiver beforehand, for example, during the paging cycle. Also, the mapping between the transmission CID and a set of tone/symbols may not necessarily be orthogonal. In one embodiment, the transmission CID may also change over time in a pseudo-random fashion which is different between different transmitter/receiver pairs. With this property, two transmitter/receiver (Tx/Rx) pairs are not likely to use the same transmission CID for consecutive time intervals.
摘要翻译：提供装置和方法用于以非正交或伪随机方式生成识别无线通信网络中的对等连接的传输连接标识符（CID）。当发射机终端意图向其对等接收机终端发送时，它只是以伪随机方式选择传输CID，而不试图避免邻近的类似传输CID。可以例如在寻呼周期期间，事先将发送机与其预期的接收机之间的生成该伪随机传输CID的方法一致。此外，传输CID和一组音调/符号之间的映射可能不一定是正交的。在一个实施例中，传输CID也可以以不同的发射机/接收机对之间的伪随机方式随时间改变。使用此属性，两个发射机/接收机（Tx / Rx）对不可能在连续的时间间隔内使用相同的传输CID。

摘要： In an ad hoc peer-to-peer communications network, timing synchronization is facilitated between two or more nodes. A node can establish an original symbol timing and receive a first timing synchronization symbol from a peer node. A timing adjustment can be calculated based in part on the first timing synchronization symbol. An adjusted symbol timing can be established by adjusting the first symbol timing by the calculated timing adjustment amount. The adjusted symbol timing can be conveyed to one or more peer nodes, in order to facilitate timing synchronization among the nodes.

摘要： Systems and methodologies are described that facilitate choosing parameters to utilize in a local area peer-to-peer network. The parameters may relate to tone spacing, cyclic prefix, symbol time, and the like. Further, the parameters may be a function of a state (e.g., peer discovery state, control related traffic state, data related traffic state,…) associated with the local area peer-to-peer network. Moreover, the local area peer-to-peer network may share spectrum with a wide area network; as such, parameters for the peer-to-peer network may be selected based on the type of wide area network (e.g., air interface technology) and/or wide area network related parameters.

摘要： A wireless terminal receives peer to peer resource control information from a base station. The peer to peer resource control information is used by the wireless terminal in a peer to peer network to control transmission scheduling and/or resource utilization. The base station sends the control signals at a first rate which is slower than the rate at which wireless terminals make transmission decisions for traffic slots. During the intervals between receipt of the base station control signals, wireless terminals make transmission decisions with regard to multiple traffic segments. The decisions are also influenced based on peer to peer signaling occurring between the wireless terminals in the network for each traffic slot. Resource utilization feedback information is provided from the wireless terminal to the base station. Based on the feedback information the base station updates the resource utilization control information and sends updated resource utilization control signals to the wireless terminals.
