Methods for reusing space, communication equipment, communication devices, and computer-readable storage media

Abstract

This invention relates to a method for reusing space, communication equipment, communication devices, and computer-readable storage media. In this method, the first-space carrier receives part or all of the Physical Layer Protocol Data Unit (PPDU) data units and the parameterized spatial reuse reception (PSRR) sent by the second-space carrier on the first band. The first band comprises one or more sub-bands with the same bandwidth. The first spatial reuse device determines, based on the value of the spatial reuse parameter (SRP) at the bandwidth resolution level and the received power level (RPL) of the PPDU PSRR at the bandwidth resolution level, the reference transmission power to send the PPDU to perform parameterized spatial reuse transmission (Parameterized Spatial Reuse Transmission, PSRT) on the second frequency band. The second band comprises one or more subbands with bandwidth. The second band and the first band overlap at least partially. The RPL of PPDU PSRR at the bandwidth resolution level is determined based on one or more of the following conditions: one or more subbands within the first band are occupied by a portion or all of the PPDU PSRR received by the first space reuse device; or the subband is not broken in the first or second band. This reduces air interference (receiving space-reusing equipment) and improves system performance.
