METHOD AND DEVICE IN UE AND BASE STATION FOR WIRELESS COMMUNICATION
First Claim
1. A method in a User Equipment (UE) for wireless communication, comprising:
- receiving a first reference signal in a first time-frequency resource set; and
transmitting first information and second information;
wherein the first information indicates the first time-frequency resource set from Q candidate time-frequency resource sets, the Q being a positive integer greater than 1;
at least two of the Q candidate time-frequency resource sets correspond to a first type and a second type respectively;
a channel measurement for the first reference signal is used for determining the second information;
a type of channel state information comprised in the second information is related to a type corresponding to the first time-frequency resource set, and the type corresponding to the first time-frequency resource set is one of the first type and the second type; and
any one type of channel state information comprised in the second information belongs to a first channel state information type set.

Abstract
The disclosure provides a method and a device in a User Equipment (UE) and a base station for wireless communication. The UE receives a first reference signal in a first time-frequency resource set, and transmits first information and second information; the first information indicates the first time-frequency resource set from Q candidate time-frequency resource sets; at least two of the Q candidate time-frequency resource sets correspond to a first type and a second type respectively; a channel measurement for the first reference signal is used for determining the second information; and a type of channel state information included in the second information is related to a type corresponding to the first time-frequency resource set. A relationship is established between the type corresponding to the first time-frequency resource set and the content of the second information, thus improving the feedback precision and efficiency of channel state information.
