Title:
METHOD AND APPARATUS FOR RECEIVING MULTICAST/BROADCAST DATA IN WIRELESS COMMUNICATION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2023/146183
Kind Code:
A1
Abstract:
The present disclosure relates to a method of receiving multicast/broadcast data by a user equipment (UE) in a wireless communication system. In particular, the method includes the steps of: receiving a first Medium Access Control (MAC) Protocol Data Unit (PDU) for a Hybrid Automatic Repeat and request (HARQ) process based on a first Group-Radio Network Temporary Identity (G-RNTI) and a first New Data Indicator (NDI); receiving a second MAC PDU for the HARQ process based on a Cell-RNTI (C-RNTI) and a second NDI, wherein the first NDI is identical with the second NDI; and receiving a third MAC PDU for the HARQ process based on a second G-RNTI and a third NDI, wherein based on the first G-RNTI being identical with the second G-RNTI and the second NDI being identical with the third NDI, the third MAC PDU is decoded with at least one of the first and the second MAC PDUs.
