摘要： A method and system for enhancing the capabilities of wireless local area network (WLAN) control frames in general, and particularly block acknowledgement (ACK) frames, such as block ACK request (BAR) frames and block ACK response (BA) frames are disclosed. Furthermore, the functionalities these frames provide are extended by indicating the types of such functionalities within the BAR or BA frame formats. This enables the BAR or BA frames to be used more flexibly and on an as-needed basis, without the restriction of simultaneously providing all functionalities. The BAR/BA setup and negotiation procedure is also modified to provide more flexibility. In another embodiment, request to send (RTS) frames or clear to send (CTS) frames are used for the purpose of granting reverse direction traffic, and may be aggregated with data 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 system for eliminating interference caused by hidden nodes is disclosed. An initiator control message is defined for an initiator, (typically a wireless station (STA)), in order to begin an aggregate frame exchange with at least one responder. The initiator control message includes information on the queue sizes at the initiator. A responder, (typically an access point (AP)), sets up the required protection for the transmission of data by the initiator based on information on the queue sizes indicated in a field of the initiator control message using a responder control message. Other STAs that receive the responder control message set parameters for a wireless medium access accordingly. In another embodiment, multiple receiver aggregate multi-poll (MMP) and power save aggregation descriptor (PSAD) control frames are configured for transmission by a non-AP STA to provide enhanced scheduling and mitigate hidden node problems.

摘要： A method and system for improving responsiveness in exchanging management and control frames in a wireless local area network are disclosed. An initiator sends a frame (action, management, control or data frame) to a responder. Upon correctly receiving the frame, the responder sends a response frame to the initiator instead of directly sending an acknowledgement (ACK) packet. The responder preferably accesses the wireless medium to send the response frame in a short inter-frame spacing (SIFS). With this scheme, a long delay associated with having to contend for the wireless medium to send the response frame is avoided and therefore, the responsiveness and timeliness of the feedback mechanism is significantly enhanced. The response frame may be piggybacked on or aggregated with another packet.

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： The present invention is related to a method and system for sending and reducing uplink feedback signaling by a wireless transmit/receive unit (WTRU) related to transmission of multimedia broadcast multicast service (MBMS) data over a high speed downlink packet access (HSDPA) channel. A Node B may pre-allocate a time/frequency region or a common channelization code for the feedback. A triggering criterion for reporting a channel quality indicator (CQI) is set and WTRUs send a CQI to a Node B only if the triggering criterion is satisfied. The triggering criterion may be a current operating CQI value at the Node B, or based on erroneous transport block reception statistics, or a predetermined time period. A feedback reduction method related to ACK/NACK includes the WTRU sending an indication of an average number of transmissions needed to successfully decode the data instead of sending an ACK/NACK for every transmission interval.

摘要： In an orthogonal frequency division multiple access (OFDMA) system including at least one base station and at least one wireless transmit/receive unit (WTRU), sub-carriers are allocated for data transmissions to multiple access WTRUs, where sub-carriers are allocated according to a consecutive sub-carrier allocation (CSA) type and a distributed sub-carrier allocation (DSA) type. Pilot signals with distributed pilot sub-carriers are transmitted and measured at each WTRU to obtain a channel quality metric for each pilot sub-carrier. Each WTRU sends feedback to the base station reporting channel quality based on the measured channel quality metrics. An allocation type is selected and adaptively switched according to channel variations in time and frequency domain.
