摘要： A method and apparatus for feeding back channel information from a first device to a second device in a wireless communication system are provided. The first device estimates channel parameters based on a signal received from the second device, and determines a set of angle parameters indicative of an angle representation of a V matrix, which is the right singular matrix of a singular value decomposition of an estimated channel matrix H. The angle parameters can be derived according to a Givens rotation method or Cosine-Sine decomposition. The first device applies a Trellis Coded Quantization (TCQ) scheme to map the angle parameters to a trellis. A Viterbi algorithm applied to the trellis generates quantized angle parameters which are transmitted to the second device.

摘要： Wireless medium reservation for simultaneous transmission of multiple downlink spatial streams to multiple receiver wireless stations during a multi-user transmit opportunity over a wireless medium, is provided. Such a reservation includes reserving a transmission period for simultaneously transmitting data from a transmitting station to multiple intended receiving stations on multiple downlink spatial streams over a wireless communication medium. Reserving the transmission period includes transmitting a multi-user request-to-send (MU-RTS) frame to the multiple receiving stations, the RTS frame including a receiver address (RA) field comprising compressed addresses for the multiple receiving stations. The MU-RTS frame includes an indication field that indicates the RTS frame as an MU-RTS without altering the RTS frame type/subtype.

摘要： The present invention provides a control function in an access point, switch, or like node on a wireless local area network. The control function operates to ensure frames transmitted by a user terminal are transmitted using an appropriate transmission priority scheme. The control function will assist and provide an appropriate priority level to the user terminal. Frames transmitted from the user terminal are passed through the control function, which will analyze priority level information provided in the frames to determine if the frames were transmitted using the appropriate transmission priority scheme. An enforcement action may be taken in response to identifying frames that were not transmitted using the appropriate transmission priority scheme.

摘要： The two types of virtual local area networks (VLANs) may be defined: p-bits-Inferred-scheduling class VLAN (p-VLAN); and VLAN-ID-Only-Inferred-scheduling class VLANs (v-VLAN). As such, upon receipt of an Ethernet frame, the type of VLAN associated with the Ethernet frame may be determined. The type of VLAN provides the receiving node with an indication of a method of determining a scheduling class. A p-VLAN supports multiple scheduling classes. For a p-VLAN, the scheduling class and drop precedence for the received Ethernet frame may be determined based on a “service map” that describes the relationship between the p-bits and forwarding treatment. A v-VLAN supports a single scheduling class. As such, the scheduling class for a received Ethernet frame may be determined based on the VLAN-ID of the received Ethernet frame. The described VLAN QoS information may be configured or signaled across the network. Advantageously, the methods may be applied in connectionless, connection-oriented and path-oriented Ethernet networks.
摘要翻译：可以定义两种类型的虚拟局域网（VLAN）：p-bits-Inferred-scheduling class VLAN（p-VLAN）; 和VLAN-ID-Only-Inferred-scheduling类VLAN（v-VLAN）。因此，在接收到以太网帧时，可以确定与以太网帧相关联的VLAN的类型。 VLAN的类型为接收节点提供了确定调度类的方法的指示。 p-VLAN支持多个调度类。对于p-VLAN，可以基于描述p位和转发处理之间的关系的“服务映射”来确定所接收的以太网帧的调度类别和丢弃优先级。 v-VLAN支持单个调度类。因此，可以基于接收的以太网帧的VLAN-ID来确定接收到的以太网帧的调度类。所描述的VLAN QoS信息可以通过网络配置或发信号通知。有利地，该方法可以应用于无连接，面向连接和面向路由的以太网。
