Abstract: Provided are a spatial reuse method, an apparatus, a device, and a medium. In the method, a first spatial reuse device receives a portion or all of a PSRR PPDU sent by a second spatial reuse device on a first frequency band. The first frequency band includes one or more subbands with a same bandwidth. The first spatial reuse device determines, based on a value of a spatial reuse parameter SRP at a granularity of the bandwidth and a received power level RPL of the PSRR PPDU at a granularity of the bandwidth, a reference transmit power for sending a PSRT PPDU on a second frequency band. The second frequency band includes one or more subbands with the bandwidth. The second frequency band and the first frequency band at least partially overlap.

Abstract: This application provides an information transmission method and a communication apparatus. The method includes: A first device sends TWT resource configuration information in a first BSS to a second device. The first device is located in the first BSS, the second device is located in a second BSS, and the first BSS and the second BSS at least partially overlap. According to the information transmission method provided in this application, TWT resource configuration information in a plurality of BSSs is shared among the plurality of BSSs in an OBSS scenario. Therefore, collision can be further avoided during data transmission in different BSSs in the OBSS scenario, thereby improving quality and assurance of data transmission between devices in the plurality of BSSs, and improving efficiency of data transmission in the OBSS scenario.

Abstract: Embodiments of this application provide a communication method between multi-link devices and an apparatus, and relate to the field of communications technologies, to reduce power consumption of a station multi-link device. The method includes: a multi-link device includes a plurality of STAs, one STA operates on one of a plurality of links, and the STA determines a primary link in the plurality of links. A STA operating on the primary link in the multi-link device may receive information sent by the AP indicating whether the STA operating on the primary link has a downlink traffic, and/or information indicating whether a STA operating on a link other than the primary link has a downlink traffic. Therefore, the STA operating on the primary link may determine a link on which the STA having a downlink traffic operates in the multi-link device.

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.
