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： A method for addressing groups of stations in a wireless communication system begins by assigning the stations in the system into a number of groups. A group identifier is signaled to each station and the group identifier is indicated in a frame for each group that has data in the frame. The addressing method can be applied to power savings for the station, wherein the station enters a power saving mode if the group identifier for the station is not present in the frame.

摘要： A method and apparatus for providing and utilizing radio link control (RLC) and medium access control (MAC) packet delivery notification are disclosed. A MAC entity tracks a delivery status of a MAC protocol data unit (PDU) and sends MAC service data unit (SDU) delivery notification to an RLC entity and/or an upper layer upon occurrence of a triggering event. The triggering event may be expiration of a timer, a packet discard decision, MAC reset, MAC re-establishment, or a request from the upper layer. The RLC entity may also track a delivery status of an RLC service data unit (SDU) and send RLC delivery notification to the upper layer. An upper layer including a header compression entity may adjust a header compression parameter based on the RLC delivery notification or the MAC delivery notification. The RLC delivery notification may be used for lossless handover. Retransmission may be performed at the upper layer based on the RLC delivery notification or the MAC delivery notification.

摘要： A method and apparatus for hybrid automatic repeat request (HARQ) transmission are disclosed. If a packet has not been successfully transmitted, it is determined whether an HARQ early termination condition is met. If the HARQ early termination condition is met, the HARQ process is terminated and the packet is discarded at the HARQ level. The HARQ early termination condition is met if a positive acknowledgement (ACK) has not been received until the number of retransmissions reaches a predetermined limit that is dynamically configured based on channel condition, measurement, etc. Alternatively, the HARQ early termination condition is met if a transmit power required for successful transmission of the packet is much higher than an actual transmit power. Alternatively, the HARQ early termination condition is met if a transport format combination (TFC) selected for retransmission is different from an optimal TFC. A higher layer may be notified of the early HARQ termination.
摘要翻译：公开了一种用于混合自动重传请求（HARQ）传输的方法和设备。如果分组未被成功发送，则确定是否满足HARQ提前终止条件。如果满足HARQ提前终止条件，则HARQ过程终止并且在HARQ等级丢弃该分组。如果尚未接收到肯定确认（ACK），直到重传次数达到基于信道条件，测量等动态配置的预定限制，则满足HARQ提前终止条件。或者，如果满足HARQ提前终止条件成功传输分组所需的传输功率远高于实际传输功率。或者，如果选择用于重传的传输格式组合（TFC）不同于最佳TFC，则满足HARQ提前终止条件。可以通知较高层HARQ早期终止。

摘要： A wireless local area network (WLAN) includes at least one high throughput-enabled access point (AP) and at least one high throughput-enabled station (STA). A STA and a target AP communicate high throughput-related information and the STA performs a basic service set (BSS) transition to the target AP based on the high throughput-related information. The high throughput-related information may be included in an IEEE 802.11r, 802.11k, or 802.11v signaling message. The STA may send measurement reports for an extended range and a normal range of an AP separately, or may send a combined measurement report for an extended range and a normal range of an AP. A network management entity may obtain current status information of the STA and the AP regarding high throughput capabilities, features and parameters and selectively enable and disable at least one of the high throughput capabilities, features and parameters of the STA and the AP.

摘要： High throughput (HT) devices are required to support defragmentation for reassembling a medium access control (MAC) service data unit (MSDU) or a MAC protocol data unit (MPDU) from its fragments, but may or may not fragment data to be transmitted. In one embodiment, a wireless transmit/receive unit (WTRU) includes a data defragmentation unit which defragments any fragmented data received by the WTRU, but the WTRU does not transmit fragmented data. In another embodiment, a WTRU includes a processor, a data fragmentation unit, a transmitter and a fragmentation selection unit. The processor determines whether or not the transmitter should transmit fragmented data. When fragmentation is desired, the processor controls the fragmentation selection unit such that the data fragmentation unit fragments data provided by the processor for transmission by the transmitter.

摘要： A system for regulating packet flow through a switch fabric and a system for verifying the transmission integrity of the fabric. In the first system, an ingress sends packets to the switching entity in a designated order and an egress receives packets from the switching entity, re-orders the packets in the designated order and sends an acknowledgement of receipt of the packets to the ingress upon re-ordering. The ingress receives acknowledgements of receipt of packets from the egress, maintains an indication of a number of packets for which an acknowledgement of receipt has not yet been received, performs a comparison between the number of packets for which an acknowledgement of receipt has not yet been received and a threshold, and regulates sending packets to the switching entity on the basis of the comparison. The principle behind the second system is based on exchanging marker packets at identifiable reference instant.
