Communication method, communication apparatus, and storage medium

Abstract

Disclosed in embodiments of the present application are a communication method, a communication apparatus, and a storage medium, which are applied to the technical field of wireless communications. In the embodiments of the present application, a terminal device determines a first identifier or a second identifier; a network device uses the first identifier or the second identifier to scramble an RAR; if the terminal device can use the first identifier to successfully descramble the RAR, it means that the RAR is feedback for a first uplink; and if the terminal device can use the second identifier to successfully descramble the RAR, it means that the RAR is feedback for a second uplink. In the embodiments of the present application, a first identifier corresponds to a first link, and a second identifier corresponds to a second link; therefore, a terminal device can determine, on the basis of different identifiers, the link for which the RAR serves as downlink feedback, so as to determine first spatial transmission information corresponding to a subsequently sent message. The present application solves the problem of incapability of sending a subsequent message due to the fact that the terminal device cannot distinguish uplinks corresponding to downlink feedback.
