METHOD AND DEVICE FOR DETERMINING PRECODING GRANULARITY

Document Type and Number:

WIPO Patent Application WO/2018/177022

Kind Code:

A1

Abstract:

Provided in an embodiment of the present disclosure are a method and device for determining a precoding granularity. The method comprises: if a receiving end is configured to have one or a combination of configuration conditions, the receiving end determining that a precoding granularity is multiple resource blocks. The above configuration conditions include conditions such as an aggregation level. The receiving end can perform accurate channel estimation according to information associated with the precoding granularity. Compared with the prior art techniques in which configuration of a PRB bundling size is performed only according to a system bandwidth, the method for precoding granularity configuration disclosed in the embodiment of the present invention is more flexible, thereby realizing further optimization of system performance.
