Abstract

The invention provides a signal transmission method and apparatus. The method comprises the following steps: determining, by a network device, first indication information, wherein the first indication information is used for indicating that N common signal blocks adopt the ith transmission mode, in the ith transmission mode, the N common signal blocks comprise Ri common signal block groups, at least one group among the Ri common signal block groups includes Pi common signal blocks, at least one group includes Ki common signal blocks, the common signal blocks of the same group satisfy quasi-co-address QCL hypothesis, N and i are integers greater than 0, and Ri, Ki, and Pi are integers greater than 0 and less than or equal to N; and sending the first indication information to a terminal. The grouping of the common signal blocks is more flexible, and the number of common information blocks included in each group is also more flexible to better support multi-beam transmission and implementation.

Description

technical field [0001] The present application relates to the field of wireless communication, and in particular to a signal transmission method and device. Background technique [0002] In the fifth generation (5th Generation, 5G) communication system, quasi-co-location (Quasi-Co-Location, QCL) can be used to assist in describing the beamforming and receiving process of the receiving side device. Specifically, the QCL may indicate some spatial characteristic parameters, such as departure angle-related parameters, arrival angle-related parameters, and the like. The parameters related to the departure angle may include: horizontal departure angle (Azimuth angle of Departure, AoD), vertical departure angle (Zenith angle of Departure, ZoD), horizontal departure angle spread (Azimuth angle spread of Departure, ASD), Vertically to the departure angle (Zenith angle spread of Departure, ZSD), etc. Arrival angle-related parameters may include: horizontal angle of arrival (Azimuth ...
