Link adaptation feedback method and transmitting device

摘要

Embodiments of the present disclosure provide a link adaptation feedback method, including: receiving, by a device, a link adaptation feedback frame sent by a communication peer end, where the link adaptation feedback frame includes a modulation and coding scheme request sequence identifier (MSI), where the MSI is configured to indicate space-time block coding type information.

主权项

1. A link adaptation feedback method, comprising:
receiving, by a device, a link adaptation feedback frame sent by a peer end communications device, wherein the link adaptation feedback frame comprises a modulation and coding scheme request sequence identifier (MSI) comprising three bits, wherein one bit of the three bits in the MSI is used to indicate space-time block coding (STBC) information, and the space-time block coding information is used to indicate whether a data frame related to the link adaptation feedback frame uses space-time block coding.
