Transport block size and rate matching for multicast communications

Abstract:

A base station may transmit a multicast transmission to a group of user equipments (UEs) that are each configured with a group radio network temporary identifier (G-RNTI). The UEs may be configured to receive the transmission using the same modulation and coding scheme (MCS) and transport block size (TBS) such that the group of UEs may receive the same transmission. In particular, a UE may receive one or more configurations for multicast transmissions, each configuration associated with a G-RNTI. The UE may determine a MCS table for the G-RNTI. The UE may determine a TBS for a multicast transmission based on an overhead value for the G-RNTI. The UE may receive the multicast transmission based on the MCS table and the TBS.
