Abstract
A user equipment, method and base station allows for performing a discontinuous reception (DRX) operation for multimedia broadcast multicast service (MBMS) transmission. When performing the DRX operation, a single cell multicast control channel (SC-MCCH) based on the H-SFN and a first value is received by the user equipment from the base station, and a single cell multicast traffic channel (SC-MTCH) based on the H-SFN and a second value is received by the user equipment from the base station.
Claims3
A user equipment comprising:
- a processor and a memory coupled to the processor, wherein the processer is configured to:
- receive multimedia broadcast multicast service (MBMS) service via single cell point-to-multipoint (SC-PTM) transmission from a cell;
- perform extended discontinuous reception (eDRX) operation for the SC-PTM transmission based on hyper system frame number (H-SFN) broadcast from the cell;
- when performing the eDRX operation, receive a single cell multicast control channel (SC-MCCH) based on the H-SFN and a first value received from the cell;
- and
- when performing the eDRX operation, receive a single cell multicast traffic channel (SC-MTCH) based on the H-SFN and a second value received from the cell.

A method comprising:
- receiving by a user equipment, multimedia broadcast multicast service (MBMS) service via single cell point-to-multipoint (SC-PTM) transmission from a cell;
- broadcasting by the cell, hyper system frame number (H-SFN) for the user equipment to perform eDRX operation;
- performing by the user equipment, the eDRX operation for the SC-PTM transmission based on the H-SFN;
- receiving by the user equipment, a single cell multicast control channel (SC-MCCH) based on the H-SFN and a first value received from the cell, when performing the eDRX operation;
- and
- receiving by the user equipment, a single cell multicast traffic channel (SC-MTCH) based on the H-SFN and a second value received from the cell, when performing the eDRX operation.

A base station comprising:
- a processor and a memory coupled to the processor, wherein the processer is configured to:
- transmit multimedia broadcast multicast service (MBMS) service via single cell point-to-multipoint (SC-PTM) transmission;
- broadcast hyper system frame number (H-SFN) for a user equipment to perform eDRX operation;
- transmit to the user equipment, a first value used for receiving a single cell multicast control channel (SC-MCCH) based on the H-SFN when performing the eDRX operation;
- and
- transmit to the user equipment, a second value used for receiving single cell multicast traffic channel (SC-MTCH) based on the H-SFN when performing the eDRX operation.
