Wireless communication method and device, and communication equipment

Abstract

The present application provides a wireless communication method and a communication device, the method comprising: a network device transmits, to a terminal, indication information of m first symbolgroups for repeated transmission of a first transport block (TB), and the terminal and the network device use the same rule to determine the quasi-co-location (QCL) hypothesis corresponding to each second symbol group in the actually used second symbol groups when the first TB is sent or received, so that the QCL hypotheses corresponding to the second symbol groups determined by the network deviceand the terminal device can be prevented from being inconsistent. Thus, the reliability and accuracy of wireless communication can be improved.

Description

technical field [0001] The embodiments of the present application relate to the communication field, and more specifically, to a wireless communication method and device, and a communication device. Background technique [0002] At present, a repeated transmission technology is known, that is, in order to improve transmission reliability, a network device schedules multiple resources (for example, symbol groups) for a terminal at a time, and the multiple resources are used to repeatedly transmit the same transport block (transport block, TB). [0003] In addition, in the repeated transmission technology, in order to make the repeatedly transmitted TB experience different channel environments, different quasi-co-location (quasi-co-location, QCL) assumptions can be used on the multiple resources, thereby further improving This ensures the robustness of the TB transmission. [0004] However, in practical applications, the multiple resources indicated by the network equipment ...

Problems solved by technology

[0004] However, in practical applications, the multiple resources indicated by the network equipment may include resources occupied by other channels or signals, or one of the resources may contain symbols of different time slots, resulting in the resources actually used for repeated transmission of TB and network equipment. The indicated resource is inconsistent. In this case, the QCL assumption corresponding to the actually used resource determined by the network device may be inconsistent with the QCL assumption corresponding to the actually used resource determined by the terminal, thereby affecting the reliability and accuracy of communication. sex
