Abstract
Embodiments of the present disclosure provide a precoding matrix indication method, user equipment, and an access device. The precoding matrix indication method includes: generating indication information, where the indication information indicates K−v non-zero weighting coefficients, the K−v non-zero weighting coefficients belong to Knon-zero weighting coefficients, v is a quantity of transport layers, the Knon-zero weighting coefficients are for constructing a precoding matrix, and the precoding matrix is constructed based on at least the Knon-zero weighting coefficients, m spatial domain vectors, and n frequency domain vectors, where the indication information is generated in a first manner when a first preset condition is met, or the indication information is generated in a second manner when a second preset condition is met; and sending the indication information.
