Abstract

Claims (44)

1 . A method by a terminal in a wireless communication system, the method comprising:

receiving system information block 1 (SIB1) that comprises a first parameter related to a number of paging frames;

determining a paging frame and a paging occasion; and

receiving a paging message based on the paging occasion of the paging frame,

wherein a paging occasion index of the paging occasion for RRC_INACTIVE state is determined based on an extended Discontinuous Reception (DRX) cycle configured by upper layer and the first parameter in case that:

the terminal supports using same paging occasion index in RRC_INACTIVE as in RRC_IDLE; and

a second parameter related to idle paging occasion is broadcast in the SIB1, and

wherein the paging occasion index of the paging occasion for RRC_INACTIVE state is determined based on the extended DRX cycle configured by Radio Resource Control (RRC) layer and the first parameter in case that:

the terminal supports using same paging occasion index in RRC_INACTIVE as in RRC_IDLE; and

the second parameter related to idle paging occasion is not broadcast in the SIB1.

2 . The method of claim 1 ,

wherein the paging message comprises a first terminal identifier.

3 . The method of claim 2 ,

wherein an uplink message comprising a second terminal identifier is transmitted by the terminal in response to the paging message.

4 . The method of claim 3 ,

wherein the second terminal identifier is comprised in the RRC message that causes state transition from RRC_CONNECTED to RRC_INACTIVE.

5 . The method of claim 2 ,

wherein the first terminal identifier is comprised in a RRC message that causes state transition from RRC_CONNECTED to RRC_INACTIVE.

6 . The method of claim 1 ,

wherein the paging frame is determined further based on a third parameter.

7 . The method of claim 6 ,

wherein the third parameter is the last n bits of a third terminal identifier.

8 . The method of claim 7 ,

wherein the third terminal identifier is a temporal terminal identifier determined by a core network entity.

9 . The method of claim 1 ,

wherein the paging frame contains starting points of one or more paging occasions.

10 . The method of claim 1 ,

wherein the paging occasion is a set of one or more physical downlink control channel (PDCCH) monitoring occasions.

11 . The method of claim 1 ,

wherein the paging frame is determined further based on an offset.

12 . The method of claim 11 ,

wherein the offset and the number of paging frames are determined based on the first parameter.

13 . A terminal in a wireless communication system, the terminal comprising:

a transceiver configured to transmit and receive a signal, and

a controller configured to control the transceiver to:

receive system information block 1 (SIB1) that comprises a first parameter related to a number of paging frames;

determine a paging frame and a paging occasion; and

receive a paging message based on the paging occasion of the paging frame,

wherein a paging occasion index of the paging occasion for RRC_INACTIVE state is determined based on an extended Discontinuous Reception (DRX) cycle configured by upper layer and the first parameter in case that:

the terminal supports using same paging occasion index in RRC_INACTIVE as in RRC_IDLE; and

a second parameter related to idle paging occasion is broadcast in the SIB1, and

wherein the paging occasion index of the paging occasion for RRC_INACTIVE state is determined based on the extended DRX cycle configured by Radio Resource Control (RRC) layer and the first parameter in case that:

the terminal supports using same paging occasion index in RRC_INACTIVE as in RRC_IDLE; and

the second parameter related to idle paging occasion is not broadcast in the SIB1.
