Patent ID: 8649310

Claim:
A communication method for multicast and broadcast service (MBS), the communication method being adapted for a base station (BS), the BS belonging to a first MBS zone, the BS comprising a processor and a transceiver, the communication method comprising the steps of: enabling the processor to set an indicator in a control channel allocation of a frame, the indicator being related to a cell-specific MBS configuration of the BS, wherein a content of the indicator comprises one of the following information: the cell-specific MBS configuration, the frame having the cell-specific MBS configuration, a size of a first MBS region of the frame, a first position of the first MBS region, and a next subframe having an MBS region, the control channel allocation being an allocation that a mobile apparatus has to read when it is in a power-saving mode and has to receive first MBS data, and the first MBS data being related to the first MBS zone; and enabling the transceiver to transmit the frame so that the mobile apparatus can derive the cell-specific MBS configuration according to the indicator in the control channel allocation without need to search the whole frame after receiving the frame.
