Abstract
A data transmission rate control terminal device receives beam indication information and scheduling information from a base station. The terminal device determines at least one beam based on a set of N candidate beam pair links (BPLs). The terminal device determines second modulation and coding indication information according to first modulation and coding indication information, and the terminal device transmits data on the at least one beam according to resource indication information and the second modulation and coding indication information.
