Abstract

The present disclosure relates to a port configuration method and device, the method comprising: receiving antenna port configuration parameters, the antenna port configuration parameters are adapted to the transmission capability information of the terminal; determining port selection parameters and demodulation according to the antenna port configuration parameters A collection of association relationships among reference signal DMRS port identifiers. In the present disclosure, the antenna port configuration parameters sent by the base station are used to determine a set of associated relationships adapted to the transmission capability of the terminal, and the DMRS port is obtained according to the determined antenna port data to configure the port, which avoids blindly configuring the port of the terminal The configuration improves the efficiency of terminal configuration and reduces the signaling overhead of configuration.

Description

technical field [0001] The present disclosure relates to the technical field of communications, and in particular to a port configuration method and device. Background technique [0002] In a communication system, when a terminal establishes a connection with a base station, it needs to configure the antenna port. In the related art, when configuring the antenna port, a complete downlink port configuration table is usually used. In this way, the related technology can complete the configuration of the downlink port. Configuration of the antenna ports of the UE. However, when configuring the antenna ports in the related art, since a complete downlink port configuration table is used, a large amount of configuration signaling is occupied and transmission resources are wasted. [0003] Therefore, it is urgent to propose a new technical solution to reduce signaling overhead, thereby saving transmission resources and improving communication efficiency.
