  • Publication number: 20230345464
    Abstract: This application provides a DMRS sending method, a DMRS receiving method, and a communication apparatus. The method includes: receiving indication information indicating a scheduled DMRS port; and sending a DMRS on the scheduled DMRS port. The scheduled DMRS port belongs to a DMRS port set, the DMRS port set includes M DMRS ports, the M DMRS ports correspond to a first time domain position and a second time domain position, and a first DMRS port set corresponding to the first time domain position is different from a second DMRS port set corresponding to the second time domain position. In this way, different DMRS port sets are mapped to the first time domain position and the second time domain position, so that more orthogonal DMRS ports can be supported, thereby improving a system capacity.

  • Publication number: 20230344749
    Abstract: This application is applicable to a multi-link group addressed traffic transmission method and an apparatus. A first access point (AP) of an AP multi-link device (MLD) sends group addressed traffic indication information indicating whether each AP of other APs of the AP MLD has a group addressed traffic, so that a station (STA) can learn whether the multiple APs have a group addressed traffic. In this way, each STA of the STAMLD does not need to listen to each AP whether each AP has a group addressed traffic. This reduces power consumption of the STA MLD. This application may be applied to a wireless local area network system that supports an IEEE 802.11ax next-generation Wi-Fi EHT protocol, for example, 802.11 series protocols such as 802.11be.
