摘要： A MIMO wireless communications device supports a dual polarized mode of antenna operation and a single polarized mode of antenna operation. Antenna mode selection is performed as a function of signal to noise ratio information and/or rank information corresponding to a communications channel matrix. One of a communications device's processing chains is switched between first and second polarization orientation antennas, e.g., vertical and horizontally polarized antennas, as a function of the antenna mode selection. In various embodiments, the dual polarized mode is advantageously used for high SNR users, while in the low SNR regime, where the capacity is limited by received power, the single polarized antenna configuration, sometimes referred to as the spatial MIMO configuration, is used.

摘要： Methods and apparatus well suited for supporting communications over different ranges in, for example, a peer to peer wireless communications system, are described. In the peer to peer network at least some of the types of signals, e.g., peer discovery signals and/or paging signals, are transmitted with no closed loop power control. An exemplary peer to peer timing structure includes air link resources allocated for a particular type of signaling in which the resources are segmented into multiple blocks which do not overlap in time, different ones of the multiple blocks being associated with different ranges. The characteristics of the basic transmission units of the multiple blocks based on range are different, e.g., tone size and symbol width are different. A wireless communications device implements the peer to peer timing structure and uses resources from different range based blocks at different times. Data traffic transmission units may be the same regardless of the range.

摘要： Methods and apparatus relating to scheduling of air link resources, e.g., traffic segments, in a wireless communications system are described. Various described methods and apparatus are well suited to wireless peer to peer networks in which traffic scheduling is decentralized, e.g. an ad hoc peer to peer network. An individual wireless terminal corresponding to a peer to peer connection which desires to transmit traffic signals make transmitter yielding decisions on a traffic slot by traffic slot basis. The transmitter yielding decision, in some embodiments, includes comparing a link quality estimate corresponding to a higher priority link intending to use the same traffic segment concurrently, to a dynamically generated transmitter yielding threshold. The dynamically generated transmitter yielding threshold is determined based on at least one of: quality of service information corresponding to its own link and historical link quality information corresponding to the higher priority link.

摘要： Methods and apparatus for wireless communications in networks, e.g., regional ad hoc peer to peer networks, are described. A communications node, e.g., a third node monitors for wireless communications between other peer communication nodes, e.g., a first node and a second node, in its local vicinity. The third node determines from the monitored wireless communication an indication of link quality corresponding to a communication link between the communication nodes which are communicating or seeking to establish a communications link. The third node generates an estimate of a link quality for a communications link between itself and the first node. Based on the indication of link quality and generated estimate of link quality, the third node decides whether or not to send a signal indicating availability to relay communication between the first and second nodes. The third node, when acting as an intermediary node after indicating its availability to so act, may receive traffic data e.g., user data communicated in a peer to peer traffic segment, from the first node. The third node communicates the received traffic data to the second node by transmitting the traffic data.

摘要： Methods and apparatus related to scheduling and/or utilization of air link traffic resources are described. A peer to peer connection holds a set of multiple connection identifiers for a plurality of successive traffic slots. Corresponding to a particular traffic slot, each of the connection identifiers in the set of connection identifiers has a different priority. Short term traffic needs are considered in the use of the multiple connection identifiers being held. For example, a communications device, corresponding to a peer to peer connection which is associated with a plurality of connection identifiers having different priorities, considers the amount and/or latency requirements of data to be transmitted at any given time when selecting which connection identifier to use when transmitting a traffic transmission request for a traffic segment which is in contention.

摘要： Methods and apparatus for wireless communications in regional networks, e.g., ad hoc peer to peer networks, are described. Wireless communications devices transmit and monitor for presence indicator signals broadcast from other peer communications devices in its local vicinity. A wireless communications device maintains a list of discovered devices in its vicinity. A first wireless communications device transmits a paging signal directly over an airlink to a second communications device, which is on its list and to which it desires to send data units, e.g., user data in a peer to peer traffic segment. In response to a received paging response signal from the second device, the first device transmits data units, intended for the second device, to a third device, which acts as an intermediary node. The power level for the data unit signal is controlled to be lower than the power level used for the paging signal.

摘要： Methods and apparatus which support the use of differently polarized antennas to schedule two or more users employing multiple antennas with different polarization, on the same communications segment, e.g. a time/frequency slab, in either the uplink or downlink are described. Various embodiments include an access node which classifies and schedules wireless terminals to segments as a function of suitability for single polarization direction communications. Some embodiments are directed to methods and apparatus for operating a communications device supporting the use of multiple antennas having different polarization, to implement a polarization based multiple access scheme. Unlike Spatial Division multiple access schemes, the users sharing a communications segment in the polarization based scheme need not be geographically well separated. Another advantage of using the proposed method is that the communications system does not necessarily have to use a complex minimum mean square error receiver or implement successive iteration cancellation techniques, thereby reducing cost and system complexity.
摘要翻译：支持使用不同极化天线来调度在相同通信段上采用具有不同极化的多个天线的两个或更多个用户的方法和装置，例如，描述在上行链路或下行链路中的时间/频率块。各种实施例包括将无线终端分类并将其调度为对于单极化方向通信的适用性的函数的接入节点。一些实施例涉及用于操作支持使用具有不同极化的多个天线的通信设备的方法和装置，以实现基于偏振的多址方案。与空间分多址方案不同，在基于偏振的方案中共享通信段的用户不需要在地理上很好地分离。使用所提出的方法的另一个优点是通信系统不一定必须使用复数最小均方误差接收器或实现连续的迭代消除技术，从而降低成本和系统复杂度。

摘要： Method and apparatus related to implementing and/or utilizing different polarization antennas with different corresponding average transmit power levels are described. Inter-cell interference is mitigated by having different cells with different power relationships between polarizations antennas. For example, a first base station transmits at a high average power level on its vertical polarization antenna and transmits at a low average power level on its horizontal polarization antenna. Concurrently, a second base station, which is adjacent to the first base station, transmits at a low average power level on its vertical polarization antenna and transmits at a high average power level on its horizontal polarization antenna. In some hexagonal deployment schemes a base station has at most two adjacent base stations using the same power level to antenna polarization direction relationship as it is using.

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. Various features and/or aspects are directed to associating group transmission request resources and/or request response resources with device identifiers as opposed to associating such resources with connection identifiers. This approach is well suited for large size groups of N members, where the number of the number of connections between members of the group is approximately N 2 . This approach provides for efficient resource utilization supporting group traffic signaling.

摘要： An improved mechanism is provided that facilitates transmission of small packets within an ad hoc peer-to-peer network. A small packet is identified to a receiver within a control channel so that its lower power can be considered in an interference management protocol implemented among local peer devices. In a traffic slot, a transmitter voluntarily backs down on the transmitter power as a smaller packet will require much lower signal-to-noise ratio. This will improve the signal energy per bit per noise power density for the transmission as well as minimize the interference caused to other wireless communications happening in the same spectrum.
