Title:
METHOD AND APPARATUS FOR RESOURCE ALLOCATION OF MBS
Document Type and Number:
WIPO Patent Application WO/2022/211351
Kind Code:
A1
Abstract:
The disclosure relates to a fifth generation (5G) or sixth generation (6G) communication system for supporting a higher data transmission rate. A method performed by a terminal for processing multicast and broadcast service (MBS) data in a wireless communication system is provided. The method includes receiving, from a base station, first downlink control information (DCI) including first resource allocation information based on a first radio network temporary identity (RNTI), receiving, from the base station, second DCI including second resource allocation information based on a second RNTI and in case that a hybrid automatic repeat request (HARQ) process identifier of the first DCI and a HARQ process identifier of the second DCI are identical, determining whether a new data indicator (NDI) of the second DCI is toggled, based on the first RNTI and the second RNTI, wherein, in case that the first RNTI corresponds to a group-radio network temporary identify (G-RNTI) and the second RNTI corresponds to a cell-radio network temporary identify (C-RNTI), whether the NDI of the second DCI is toggled is determined based on an NDI value of the first DCI and an NDI value of the second DCI.
