Abstract: A convolutional code rate matching method and a communication apparatus are provided. A puncturing pattern of a second codeword at a second code rate is obtained based on a puncturing pattern of a first codeword at a first code rate. A second puncturing location set of the second codeword is a subset of a first puncturing location set of the first codeword. When a transmit device decreases a code rate from the first code rate to the second code rate, a redundant bit is sent at a location of a complementary set of the second puncturing location set relative to the first puncturing location set. Compared with the first puncturing location set, the second puncturing location set may obtain more incremental redundant bits, to decrease a channel encoding rate. This can improve decoding performance of a convolutional code.

Abstract: A method of communication between a first node and a second node operating in a communications network. The method includes sending, by the first node, to the second node, a first transmission to configure a communication channel between the first node and the second node. The first transmission includes a first frame including a first capability indicator. The first capability indicator indicates a first MU-MIMO capability of a transmitter of the first node. The first multi-user (MU)-MIMO capability includes a first Modulation and Coding Scheme (MCS) processable by the first node or a first number of spatial streams (NSS) processable by the first node.

Abstract: The present disclosure relates to low-density parity-check (LDPC) encoding methods and apparatus. One example method includes encoding k information bits by using a submatrix of ((n−k)/Z+j) rows and (n/Z+j) columns at an upper left corner of a check matrix H based on a first transmission code rate R satisfying R=k/(n+j×Z), obtaining a first codeword including the k information bits and (n−k+j×Z) redundant bits, and sending the first codeword to a receive end.

Abstract: Systems and methods for non-trigger based sounding is provided. According to one aspect, a method is provided. The method includes, sending, by a first access point (AP) to a station (STA), a null data packet announcement (NDPA) frame. The NDPA frame may include a first indication indicating a multi-user (MU) channel state information (CSI) feedback (FB) type. The method may further include sending, by the first AP to the STA, a first null data packet (NDP). The method may further include receiving, by the first AP from the STA, a CSI report frame based on the MU CSI FB.

Abstract: A method for an access point to schedule obtaining frames from stations connected thereto is provided. Real-time applications provide frames and frame due dates to the stations. The frames and their due dates are stored in respective buffers of the stations. Each station identifies the earliest due date of all its buffered frames and provides the earliest due date to the access point. The access point orders the due dates and schedules the stations according to the order of the due dates. The access point then communicates with the stations according to the schedule and obtains the frames. A WLAN system implementing the method is also provided.

Abstract: Efficient and accurate sensing measurements and reporting with multiple responders in 60 GHz WLAN is accomplished by conducting the measurements and reporting in multiple sub-channels separated in a frequency domain, or in a space domain, or both. Measurements, via sensing PPDUs, can be transmitted in parallel in time by multiple devices. Messaging related to communicating reporting of sensing results can also be transmitted in parallel in time by multiple devices. This parallelization is facilitated by the use of the multiple sub-channels in frequency or spatial domain.
