Embodiment Construction

[0136] The embodiment of the present application provides an information indication and determination method and device, and a computer storage medium, which are used to indicate the QCL group information of the DMRS port, so that the terminal determines the QCL group information of the DMRS port.

[0137] The basic pattern (front-load DMRS) configuration of DMRS includes the following situations:

[0138] Configuration1:

[0139] The number of DMRS symbols is 1: a combination (Combination, comb) 2+cyclic shift (cyclic shifts, CS) 2 is adopted, and a maximum of 4 ports is supported.

[0140] See figure 1 , where comb2 is frequency domain multiplexing, for example, between ports 0 and 2 is the multiplexing relationship of comb2. CS2 uses cyclic shifts to multiplex sequences between ports. For example, between ports 0 and 1 is the multiplexing relationship of CS2.

[0141] The number of DMRS symbols is 2: comb2+CS2+TD-OCC ({1, 1} and {1, -1}) is used, and a maximum of 8 ports...

Abstract

Disclosed in the present application are a data transmission method, an information determining method, an apparatus and a computer storage medium, for use in indicating QCL set information of a DMRS port, so that a terminal determines QCL set information of the DMRS port. The data transmission method provided in an embodiment of the present application comprises: determining QCL set information of a demodulation reference signal (DMRS) port; and notifying a terminal of the QCL set information.

Description

technical field [0001] The present application relates to the technical field of communications, and in particular to information indication, determination methods and devices, and computer storage media. Background technique [0002] In a new radio technology (New Radio, NR) system, a data demodulation process needs to perform channel estimation based on a demodulation reference signal (Demodulation Reference Signal, DMRS). In the prior art, the DMRS in the NR system will use the same precoding manner as the corresponding data layer for transmission. [0003] However, in the prior art, there is a lack of an indication and a determination scheme for DMRS port-related information. Contents of the invention [0004] The embodiment of the present application provides an information indication and determination method and device, and a computer storage medium, which are used to indicate the QCL group information of the DMRS port, so that the terminal determines the QCL group ...
