摘要： Certain aspects of the present disclosure provide techniques for signaling extended sizes for Medium Access Control (MAC) Protocol Data Unit (MPDU), Aggregated MPDU (A-MPDU) and Aggregated MAC Service Data Unit (A-MSDU) frame formats. A first technique proposes modifications to the current specifications of the IEEE 802.11n standard in order to allow for longer MPDUs in an A-MPDU. This technique reuses the IEEE 802.11n signaling format and utilizes reserved bits to convey the new information. The second technique proposes a new signaling mechanism to convey the extended sizes for the MPDU, A-MPDU and the A-MSDU through a very high throughput (VHT) capability element.

摘要： Techniques for supporting communication over an extended range in a wireless network are disclosed. In one aspect, a station sends multiple messages of a given type for different operating modes. These messages can be detected by stations with different capabilities, which may avoid collisions between stations. In one design, a first station receives a Request-to-Send (RTS) message from a second station having data to send. The first station sends a first Clear-to-Send (CTS) message and also a second CTS message in response to the RTS message. The second CTS message has an extended range as compared to the first CTS message. The first station thereafter (i) receives data sent by the second station in response to the second CTS message and (ii) sends an acknowledgement having an extended range.

摘要： Certain aspects of the present disclosure provide techniques and apparatus for signaling the bandwidth to be used for wireless communications using an RTS/CTS (Request to Send/Clear to Send) frame exchange, providing for bandwidths of at least 20 MHz, 40 MHz, 80 MHz, 160 MHz, or higher. This exchange of bandwidth information may be performed implicitly—by determining the channels in which the RTS/CTS frames are actually sent—or explicitly. In addition to this bandwidth information exchange, aspects of the present disclosure may also allow for Network Allocation Vector (NAV) protection in multiple channels. In this manner, the wireless medium may be reserved, and the transmission may be protected from hidden nodes.

摘要： A transmission parameter for a link in a wireless network is adapted for a current simultaneous transmission based on a loss parameter. The loss parameter is useable to determine an allocation for a wireless node of a plurality of wireless nodes participating in the simultaneous transmission. In some examples, the selected transmission parameter and loss parameters for a previous transmission, along with the loss parameter for the current simultaneous transmission are used to determine the transmission parameter. In some embodiments, an access point (AP) determines and communicates a loss parameter to a plurality of access terminals (AT). Each AT determines a modulation and coding scheme (MCS) based at least in part on the loss parameter. Each AT simultaneously transmits at least one data stream to the AP in accordance with the determined MCS. In some other embodiments, the transmission rate for simultaneous downlink communications is similarly adapted.
摘要翻译：无线网络中的链路的传输参数适用于基于丢失参数的当前同时传输。丢失参数可用于确定参与同时传输的多个无线节点中的无线节点的分配。在一些示例中，用于先前传输的所选择的传输参数和丢失参数以及当前同时传输的丢失参数被用于确定传输参数。在一些实施例中，接入点（AP）确定并向多个接入终端（AT）传送丢失参数。每个AT至少部分地基于损失参数确定调制和编码方案（MCS）。每个AT根据所确定的MCS同时向AP发送至少一个数据流。在一些其他实施例中，用于同时下行链路通信的传输速率同样适应。

摘要： Systems, methods, and devices for acknowledging communications from a plurality of wireless devices in a wireless network are described herein. In some embodiments, an access point for the wireless network transmits a group acknowledgment (ACK) to indicate whether communications (packets) from the plurality of wireless devices have been received or correctly decoded within some time interval. Each wireless device may have a different time interval associated with it. For some embodiments, the time interval for a wireless device is relative to when a previous group ACK was sent. A group ACK may include a bitmap. In some embodiments, the bitmap indicating whether a communication has been received or correctly decoded may be transmitted as part of a beacon.

摘要： Methods, devices, and systems for retransmitting Media Access Control (MAC) protocol data units (MPDUs) in a multi-user multiple-input and multiple-output (MU-MIMO) communication system are disclosed. Concurrent data streams within a first transmission window are transmitted. Each concurrent data stream is associated with a different recipient and includes an equal number of MPDUs. An indication of a retransmission subset of the MPDUs to be retransmitted for each concurrent data stream may be obtained if errors are present. The retransmission subset for each concurrent data stream is retransmitted within a second transmission window. A length of the second transmission window is as long as the longest of the retransmission subsets of the concurrent data streams. One or more new MPDUs may be added to the concurrent data streams in the second transmission window so that each concurrent data stream in the second transmission window carries a same number of MPDUs.

摘要： The deferral mechanism described herein may improve medium reuse in a wireless network with transmit power imbalances. For example, in one embodiment, an apparatus employing the deferral mechanism described herein may comprise a receiver to sense a data unit transmitted on a medium associated with the wireless network, wherein the data unit may comprise information indicating a transmit power associated therewith. Furthermore, the apparatus may comprise one or more processors to initiate a transmission on the medium associated with the wireless network if the apparatus is not an intended receiver of the sensed data unit, the transmit power associated with the data unit exceeds a transmit power associated with the apparatus, and a received power associated with the data unit does not equal or exceed a clear channel assessment threshold plus a difference between the transmit power associated with the data unit and the transmit power associated with the apparatus.

摘要： Certain aspects of the present disclosure provide techniques and apparatus for using a Media Access Control (MAC) address of a station (STA) sending a direct link multi-user multiple-input multiple-output (MU-MIMO) transmission such that one or more STAs receiving the transmission may interpret a group identifier (ID) indicating a group to which the STAs belong. Using the group ID and the MAC address allows a STA to independently manage its group IDs, independent of an access point (AP) or other STAs in a Basic Service Set (BSS).
