US 10,945,252 B2 · Method and apparatus for transmitting and receiving control channel and data channel for NR system

Abstract

Provided is a scheduling information transmission/reception method and apparatus for an NR system in a wireless communication system. A method for receiving, by a terminal, scheduling information for data transmission or reception in a wireless communication system according to one aspect of the present invention may comprise the steps of: receiving, from a base station, information indicating a first physical resource supporting a first subcarrier spacing within a time interval and a second physical resource supporting a second subcarrier spacing within the time interval; receiving at least one of first scheduling information for the first physical resource and second scheduling information for the second physical resource; and performing the data transmission or reception on the basis of the at least one of the first scheduling information and the second scheduling information.

Dependent claims

A method comprising:

receiving, by a wireless device from a base station, one or more radio resource control (RRC) signals indicating a number of first bandwidth parts configured for the wireless device;
receiving, by the wireless device, downlink control information (DCI) comprising a first indicator field that indicates at least one of the first bandwidth parts, wherein a bitwidth of the first indicator field is based on the number of the first bandwidth parts configured for the wireless device;
determining, based on the bitwidth and based on the DCI, a value of the first indicator field;
determining, based on the value of the first indicator field, one or more resources of the at least one of the first bandwidth parts;
and
performing, based on the one or more resources, a data communication with the base station.
