Abstract
The present disclosure relates to a wireless communication system, and a method, performed by a terminal, of transmitting and receiving control information in a wireless communication system according to an embodiment may include receiving, from a base station, an indication of whether to perform dynamic precoding resource block (PRB) bundling through higher layer signaling and, when the dynamic PRB bundling is indicated, dynamically determining a size of a precoding resource block group (PRG) based on downlink control information (DCI).
Claims12
A method, performed by a terminal, of transmitting and receiving control information in a wireless communication system, the method comprising:
- receiving, from a base station, configuration information on dynamic precoding resource block (PRB) bundling through higher layer signaling;
- receiving, from the base station, downlink control information (DCI) including a PRB bundling size indicator;
- in case that the PRB bundling size indicator indicates ‘0’, setting a PRB bundling size by using one value configured based on the received configuration information;
- in case that the PRB bundling size indicator indicates ‘1’:
- determining one of two values configured based on the received configuration information, by comparing a scheduled PRB size and a threshold value related with a bandwidth part size, and
- setting the PRB bundling size by using the determined value;
- and
- receiving, from the base station, data scheduled by the DCI based on the set PRB bundling size.
A method, performed by a base station, of transmitting and receiving control information in a wireless communication system, the method comprising:
- transmitting, to a terminal, configuration information on dynamic precoding resource block (PRB) bundling through higher layer signaling;
- in case that a PRB bundling size is determined by using one value configured based on the configuration information, determining a PRB bundling size indicator to indicate ‘0’;
- in case that the PRB bundling size is determined by using one of two values configured based on the configuration information, based on a scheduled PRB size and a threshold value related with a bandwidth part size, determining the PRB bundling size indicator to indicate ‘1’;
- transmitting, to the terminal, downlink control information (DCI) including the PRB bundling size indicator;
- and
- transmitting, to the terminal, data scheduled by the DCI based on the determined PRB bundling size.
