    摘要： A method and system applies MAC transmission opportunity (TXOP) protection for multiple mode operation in a WLAN system. In particular, MAC mechanisms are defined to support multiple mode CTS frames, and multiple mode CF-End frames sent by the AP, each in a format appropriate for the corresponding mode which also applies to a single mode as a trivial case. MAC mechanisms permit truncation of TXOP duration for releasing the unused portion of the TXOP when no further data for transmission is available. Release of unused protected TXOP is possible for both protected AP transmissions and STA transmissions.

    摘要： A method and apparatus for securing the wireless transmission of an aggregated frame are disclosed. An aggregated frame is generated by aggregating at least one subframe and a security field. The security field is used to secure the entire aggregated frame. The contents of the security field may be generated from a group key or a pairwise key. For example, the security field may include an initialization vector (IV), an extended IV (EIV), a message integrity code (MIC) and an integrity check value (ICV). When a group key is used for a group of receivers, the group key may be changed as a new receiver enters into the group or an existing receiver leaves the group. Alternatively, the group key may be changed periodically. The subframes may be data frames, control frames, management frames, action frames or any type of frames.

    摘要： The present invention is a method and apparatus for resource allocation signaling for grouping user real time services. Uplink signaling for voice activity reporting of each user's transition between an active state and an inactive voice state is sent from a wireless transmit/receive unit to a Node B. Radio resource allocation to users of a wireless communication system varies based on user measurement reporting, a pre-determined pattern such as frequency hopping, or a pseudorandom function. Grouping methods are adjusted to better utilize the voice activity factor, so that statistical multiplexing can be used to more efficiently utilize physical resources.

    摘要： A receiver sends hybrid automatic repeat request (H-ARQ) feedback for a current packet and at least one previous packet, whereby an error is detected based on the H-ARQ feedback. The receiver sends H-ARQ feedback with an identification of the packet or a sequence number of a packet that the receiver expects to receive next. The receiver stores a packet in a memory before combining the packet with a previously received packet, and decodes the stored packet after failing to decode a combined packet to avoid a corruption error. The receiver may set a timer when sending a NACK. If the receiver fails to receive a packet until expiration of the timer, the receiver initiates a process for recovering the packet. Each H-ARQ feedback may be associated with other attributes. Some H-ARQ processes may operate in an asynchronous mode while others in a synchronous mode in the same direction.

    摘要翻译： 接收机为当前分组和至少一个先前分组发送混合自动重传请求（H-ARQ）反馈，由此基于H-ARQ反馈检测到错误。 接收机发送H-ARQ反馈，其中包含分组的标识或者接收机期望接收的分组的序列号。 在将分组与先前接收到的分组组合之前，接收机将分组存储在存储器中，并且在未组合分组解码之后对存储的分组进行解码以避免损坏错误。 接收机可以在发送NACK时设置定时器。 如果接收方在定时器到期之前无法接收到数据包，则接收方发起恢复数据包的过程。 每个H-ARQ反馈可以与其他属性相关联。 一些H-ARQ进程可以以异步模式工作，而其他H-ARQ进程可以在同步方向上工作。

    摘要： A method and system for supporting voice over Internet protocol (VoIP) services over a wireless communication network are disclosed. Data is encoded at a coding rate specified by a controller for generating a VoIP packet. Among the encoded data, bits sensitive to errors and bits not sensitive to errors are identified and error protection is performed separately by a medium access control layer and/or physical layer. A header of the VoIP packet may be selectively compressed in accordance with an indication from the controller. A user datagram protocol (UDP)-Lite may be used for partial coverage of the sensitive bits. A comfort noise may be generated by a receiving end during a silence period without receiving a comfort noise packet from a transmitting end. If the VoIP packet is not fit into a currently assigned radio resource, the VoIP packet may be fragmented.

    摘要： Each of a plurality of packets in a particular flow is classified into one of a plurality of quality of service (QoS) classes based on information about each packet. Each packet is then adaptively processed based on the QoS class for each packet. The classification may be performed based on media information included in a session description protocol (SDP) messaging. The classification may also be performed based on a real-time transmit protocol (RTP) payload, an RTP header, a transmission control protocol (TCP) header, a user datagram protocol (UDP) header, and an Internet protocol (IP) header. The packets may be transmitted using multiple system architecture evolution (SAE) radio bearers each of which is used to deliver differentiated QoS requirements. The packets may be mapped to eigen-modes based on the QoS class of each packet such that a packet requiring a higher level of QoS is mapped to a stronger eigen-mode.
