  • Patent number: 11356213
    Abstract: Transmitters consider the size of a gap segment adjacent to at least one negatively acknowledged (NACKed) Radio Link Control (RLC) Service Data Unit (SDU) when considering when and/or how to concatenate one or more NACKed SDU segments for retransmission. Depending on which RLC SDU segment(s) is/are NACKed, e.g., considering the size of NACKed segments in relation to Protocol Data Unit (PDU) header size(s) needed, the transmitter implements a single RLC SDU retransmission or multiple RLC SDU segment retransmissions. In so doing, the solution presented herein not only defines how such transmissions occur, but also provides improved efficiency when retransmitting such NACKed SDU segments.

  • Patent number: 11271617
    Abstract: This disclosure provides systems, devices, apparatus and methods, including computer programs encoded on storage media, for null data packet (NDP) based implicit sounding and calibration for a wireless local area network (WLAN). An AP may perform a calibration procedure with one or more stations (STAs) that involves NDP transmissions. The AP may calibrate an effective downlink channel response to an effective uplink channel to compensate for transmit and receive chain differences. The AP may initiate implicit sounding by transmitting a downlink message that includes an uplink NDP announcement frame to the one or more STAs, prompting uplink multi-user (MU) NDP transmission. The AP may estimate the uplink channel based on measuring the received NDPs and mirror the estimated uplink channel for reciprocal downlink channel estimation and precoding generation. The AP may perform MU multiple input multiple output (MIMO) downlink transmission that is precoded based on the channel estimation.
