Abstract: A method includes sending a sequence number acknowledgement (SN-ACK) from a first device to a second device. The SN-ACK identifies a last consecutively correctly received data unit and includes a retry bit indicating whether at least one data unit of the plurality of data units was received by the first device subsequent to the last consecutively correctly received data unit. The method also includes, when the retry bit has a first value, sending a block acknowledgement (BA) after sending the SN-ACK. The BA includes a bitmap, where each particular bit of the bitmap indicates whether a corresponding data unit was correctly received. When the retry bit has a second value and one or more of the plurality of data units were incorrectly received by the first device, the first device receives a retransmission of one or more data units without sending the BA to the second device.

Abstract: Systems and methods for communicating in a wireless communication system are described. One implementation is provided for effectively resetting stations within a wireless communication system. For example, a signal indicating the end of a contention free period may be transmitted from a device requesting the contention free period to another peer device or an access point. The peer device or access point may be configured to then transmit the occurrence of the end of the contention free period to other devices of the wireless communication system.

Abstract: Methods and apparatus are described which increase the probability and/or frequency that devices with comparatively faster clocks in a network than other devices in the network will transmit beacon signals are described. As a result, devices with faster clocks will tend to drive system synchronization to convergence faster than if all devices transmitted beacons at the same rate, thus facilitating more reliable maintenance of system synchronization since the devices with faster clocks will tend to transmit more frequently.

Abstract: Certain aspects of the present disclosure provide techniques and apparatus for transmitting, receiving, and acknowledging MAC protocol data units (MPDUs), allowing single bits in a Block Acknowledgment (BA) bitmap to acknowledge receipt of multiple MPDUs. As a result, a greater number of MPDUs may be acknowledged than if each bit acknowledged only a single MPDU. By reducing the overhead associated with a re-transmission bitmap, a greater number of MPDUs may be aggregated, thereby increasing overall throughput.

Abstract translation: 本公开的某些方面提供用于发送，接收和确认MAC协议数据单元（MPDU）的技术和装置，允许块确认（BA）位图中的单个比特确认多个MPDU的接收。 因此，如果每个位只确认一个MPDU，则可以确认更多数量的MPDU。 通过减少与重传位图相关联的开销，可以聚合更多数量的MPDU，从而增加总吞吐量。

Abstract: In a first aspect, an aggregated packet (A-MPDU) includes packets (MPDUs) and EC-Blocks (Error Correction Blocks) containing error correction coding information. A transmitter uses a Fountain coding scheme (for example, Raptor or RaptorQ) to generate the error correction coding information from the MPDUs. If a receiver detects an error in a received MPDU, then the receiver uses the error correction coding information from the EC-Blocks to correct the error. In a second novel aspect, a determination is made as to whether a change in error rate is more likely due to collisions or to a low SNR. If the determination is that the change is due to collisions then the MCS index is adjusted to restore a target error rate, whereas if the determination is that the change is due to a low SNR then the number of EC-Blocks per A-MPDU is adjusted to restore the target error rate.

Abstract: A communication device for transmitting beamformed signals using implicit channel sounding is described. The communication device includes a processor and instructions stored in memory. The communication device receives one or more sounding signals and computes a channel estimate based on the one or more sounding signals. Frequency offset compensation is applied to the channel estimate by the communication device. The communication device also computes a precoding matrix based on the channel estimate and transmits a beamformed signal using the precoding matrix. Another communication device for receiving beamformed signals using explicit channel sounding is also described. The communication device includes a processor and instructions stored in memory. The communication device receives one or more sounding signals, computes a channel estimate based on the one or more sounding signals and applies amplitude compensation to the channel estimate. The communication device also sends estimated channel data and receives a beamformed signal.
