Title:
METHOD AND APPARATUS FOR TRANSMITTING CONTROL INFORMATION
Document Type and Number:
WIPO Patent Application WO/2018/166416
Kind Code:
A1
Abstract:
Provided is a method for transmitting control information, wherein the method is executed in a communication system using at least two division modes to divide time-frequency resources used for transmitting control information, and a plurality of time-frequency resource blocks divided by means of the at least two division modes are of a nested structure. The method comprises: determining, from a plurality of time-frequency resource blocks, a first time-frequency resource block used for sending first control information; dividing the first control information into m information segments; according to the m information segments, generating m pieces of information to be sent, wherein each piece of information to be sent comprises corresponding information segments, information i to be sent comprises information segments i and check sequences i, and the check sequences i are generated according to the information segments i, i ϵ [1, m]; performing polar code encoding on the m pieces of information to be sent so as to generate a symbol sequence; and by means of the first time-frequency resource block, sending the symbol sequence. The present invention can reduce resource overheads for transmitting control information, thereby reducing the calculation complexity and processing delay of blind detection.
