Title:
METHOD AND DEVICE FOR SENDING CONTROL INFORMATION AND DETERMINING DIFFERENT STATES OF CONTROL INFORMATION
Document Type and Number:
WIPO Patent Application WO/2019/091192
Kind Code:
A1
Abstract:
Disclosed in the present application are a method and a device for sending uplink control information and determining the different states of the uplink control information, comprising: on the basis of uplink control information to feed back and a mapping relationship between different states of the uplink control information and cyclic shift, a terminal determines a cyclic shift value corresponding to the uplink control information to feed back; and the terminal uses the cyclic shift value to send the uplink control information to feed back. By means of planning the mapping relationship, when a plurality of different terminals implement multiplexing transmission, the present application allows there to be a certain interval between the cyclic shifts used by the same control information state, reducing the likelihood of erroneous detection during demodulation by the receiving end, and enhancing transmission performance.
