METHOD AND APPARATUS FOR TRANSMITTING/RECEIVING SIGNAL FOR GROUPCAST IN WIRELESS COMMUNICATION SYSTEM - A simplified explanation of the abstract

This abstract first appeared for US patent application 18040785 titled 'METHOD AND APPARATUS FOR TRANSMITTING/RECEIVING SIGNAL FOR GROUPCAST IN WIRELESS COMMUNICATION SYSTEM

Simplified Explanation

The abstract describes a communication system that supports higher data transmission rates than 4G LTE.

  • The system is designed for 5G or 6G communication systems.
  • The method involves a transmission apparatus in a wireless communication system.
  • The transmission apparatus transmits control information via a physical downlink control channel (PDCCH).
  • The first control information is for scheduling a group common-physical downlink shared channel (GC-PDSCH) used for multicast data transmission.
  • The first control information includes information related to hybrid automatic repeat request (HARQ) feedback for the multicast data.
  • The transmission apparatus also transmits second control information via the PDCCH.
  • The second control information is for scheduling a physical downlink shared channel (PDSCH) used for unicast data transmission.
  • The second control information includes information related to HARQ feedback for the unicast data.


Original Abstract Submitted

The present disclosure relates to a 5G or 6G communication system for supporting a higher data transmission rate than a 4G communication system such as LTE. According to various embodiments of the present disclosure, a method performed by a transmission apparatus in a wireless communication system may be provided. The method may comprise the steps of: transmitting, via a physical downlink control channel (PDCCH), first control information for scheduling a group common-physical downlink shared channel (GC-PDSCH) via which multicast data is transmitted, including information related to hybrid automatic repeat request (HARQ) feedback for the multicast data; and transmitting, via the PDCCH, second control information for scheduling a physical downlink shared channel (PDSCH) via which unicast data is transmitted, including information related to HARQ feedback for the unicast data.
