Methods of transmitting and receiving data in mobile transmission system
First Claim
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, andwherein each of the plurality of POs corresponds to a 1 millisecond time interval.

Abstract
A method for transmitting and receiving data in a mobile communication system is disclosed. The data transmission method for allowing a transmission end of the mobile communication system to transmit data to at least one reception end via at least one physical channel includes, transmitting a reception indicator, which indicates whether at least one second physical channel is received, via a first physical channel, such that at least one reception end can determine whether the at least one second physical channel is received using the reception indicator, and transmitting data via a third physical channel controlled by the first physical channel. So, a sleeping time for reducing power consumption can be explicitly indicated by the above data communication method, such that power consumption required for transmitting and receiving data can be minimized.

10. A method of receiving data from a transmission end in a discontinuous reception (DRX) cycle comprising a plurality of paging occasions (POs) in a mobile communication system, the method comprising:
-
receiving 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); receiving second control information via a second physical control channel at a next PO of the first PO in the DRX cycle if the 2-bit reception indicator has a first value, the second physical control channel being CRC-masked with the paging RNTI; entering a sleep mode at the next PO of the first PO in the DRX cycle and waking 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 if the 2-bit reception indicator has a second value, the third physical control channel being CRC-masked with the paging RNTI; and entering a sleep mode from the next PO of the first PO to a last PO in the DRX cycle if the 2-bit reception indicator has a third value, 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, and wherein each of the plurality of POs corresponds to a 1 millisecond time interval. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18)
