Abstract
Apparatus and methods are provided for multicast broadcast service (MBS) transmission and reception on secondary cell (SCell) or non-serving cell. In one novel aspect, the UE receiving unicast from a serving PCell, reports assistance information for receiving MBS to the PCell and receives MBS from the non-serving cell or the SCell simultaneously with the reception of the unicast. In one embodiment, the assistance information includes one or more elements comprising supported band combination, common frequency resource (CFR) configuration, the number of component carrier, MIMO layer, modulation order and subcarrier spacing. In one embodiment, the UE receives adjustment configuration for the unicast in preparation for the MBS reception. In one embodiment, one or more CCs for the unicast is deactivated/released for the MBS reception. In one embodiment, the two-step procedure, which is the broadcast control channel (BCCH) and MBS control channel (MCCH), is used for the MBS reception.
