Title:
SYNCHRONIZATION SIGNAL BASED MULTICAST TRANSMISSION
Document Type and Number:
WIPO Patent Application WO/2022/000295
Kind Code:
A1
Abstract:
Methods, systems, and devices for wireless communications are described. A base station may transmit one or more synchronization signal blocks (SSBs), each SSB including a system information block (SIB), to one or more user equipments (UEs). A UE of the one or more UEs may select an SSB with a corresponding SSB index for receiving a SIB and subsequently a multicast transmission from the base station. The multicast transmission may include transmitting a multicast control channel, a multicast traffic channel, or both. The SIB may include one or more parameters for receiving the multicast transmission. The UE may identify one or more monitoring occasions for monitoring a physical downlink control channel for scheduling the multicast transmission based on the SSB index. The UE may receive the multicast transmission in accordance with the one or more parameters from the physical downlink control channel during the one or more monitoring occasions.
