Abstract:
1. A method of transmitting data to at least one reception end in a discontinuous reception (DRX) cycle comprising a plurality of paging occasions (POs) in a mobile communication system, the method comprising: transmitting first control information comprising a 2-bit reception indicator via a first physical control channel at a first PO of the DRX cycle, the first physical control channel being cyclic redundancy check (CRC)-masked with a paging radio network temporary identifier (RNTI), wherein if the 2-bit reception indicator has a first value, the at least one reception end receives second control information via a second physical control channel at a next PO of the first PO in the DRX cycle, the second physical control channel being CRC-masked with the paging RNTI, wherein if the 2-bit reception indicator has a second value, the at least one reception end enters a sleep mode at the next PO of the first PO in the DRX cycle and wakes up to receive third control information via a third physical control channel at a next PO of the next PO of the first PO in the DRX cycle, the third physical control channel being CRC-masked with the paging RNTI, wherein the paging RNTI indicates that each of the first physical control channel, the second physical control channel and the third physical control channel is used for receiving a paging message, wherein if the 2-bit reception indicator has a third value, the at least one reception end enters a sleep mode from the next PO of the first PO to a last PO in the DRX cycle, and wherein each of the plurality of POs corresponds to a 1 millisecond time interval.
