Device and method for transmitting downlink control information in a wireless communication system

摘要

A Downlink Control Information (DCI) processing device and method for a wireless communication system that encodes/decodes downlink control information based on a payload size of DCI format. The method includes determining a payload size of a first DCI format; and determining a payload size of a second DCI format by appending padding bits to the second DCI format until the payload size of the second DCI format is not an ambiguous size and is not equal to the payload size of the first DCI format.

1. A method for generating downlink control information (DCI) by a transmitter, the method comprising:
identifying, by a transmitter, information bits in a first DCI and information bits in a second DCI; appending, by the transmitter, if a number of the information bits in the second DCI is equal to a number of the information bits in the first DCI, one bit of value zero to the second DCI; appending, by the transmitter, if the number of the information bits in the second DCI belongs to one of ambiguous sizes, one or more zero bits to the second DCI and identifying a payload size including the one or more zero bits of the second DCI based on the ambiguous sizes and the payload size of the first DCI; and transmitting, by the transmitter, the second DCI to a receiver, wherein appending one or more zero bits to the second DCI and identifying the payload size comprises appending the one or more zero bits to the second DCI and identifying the payload size including the one or more zero bits until the payload size including the one or more zero bits of the second DCI does not belong to one of the ambiguous sizes and the payload size including the one or more zero bits of the second DCI is not equal to a payload size of the first DCI based on a result of the identification, and wherein the transmitted second DCI is received based on the payload size of the second DCI.
