Method and apparatus for transmitting and receiving paging in a wireless communication system
The present disclosure relates to a communication method and system for converging a 5th-Generation (5G) communication system for supporting higher data rates beyond a 4th-Generation (4G) system with a technology for Internet of Things (IoT). The present disclosure may be applied to intelligent services based on the 5G communication technology and the IoT-related technology, such as smart home, smart building, smart city, smart car, connected car, health care, digital education, smart retail, security and safety services. The method performed by a terminal in a wireless communication system is provided. The method comprises identifying a first value of a time offset between a physical downlink control channel (PDCCH) slot and a physical downlink shared channel (PDSCH) slot; receiving, from a base station, downlink control information (DCI) on a PDCCH associated with a paging, the DCI indicating a second value of the time offset larger than the first value; and receiving, from the base station, a paging message on a PDSCH based on the second value.
1 . A method performed by a terminal in a wireless communication system, the method comprising:
receiving, from a base station, system information including an indicator associated with a cross-slot scheduling for a paging;
determining whether the terminal supports the cross-slot scheduling for the paging;
in case that the terminal supports the cross-slot scheduling for the paging, identifying a first value of a time offset between a physical downlink control channel (PDCCH) slot and a physical downlink shared channel (PDSCH) slot, the first value being predetermined;
receiving, from the base station, downlink control information (DCI) on a PDCCH associated with a paging radio network temporary identifier (P-RNTI), the DCI indicating a second value of the time offset larger than the first value; and
receiving, from the base station, a paging message on a PDSCH based on the second value.
2 . The method of claim 1 , wherein identifying the first value further comprises:
receiving, from the base station, system information including the first value; and
identifying the first value included in the received system information.
3 . The method of claim 1 , wherein the PDSCH including the paging message is received after the PDCCH associated with the paging is processed.
4 . A method performed by a base station in a wireless communication system, the method comprising:
identifying a first value of a time offset between a physical downlink control channel (PDCCH) slot and a physical downlink shared channel (PDSCH) slot, wherein the first value is predetermined;
transmitting, to a terminal, system information including an indicator associated with a cross-slot scheduling for a paging;
transmitting, to the terminal, downlink control information (DCI) on a PDCCH associated with a paging radio network temporary identifier (P-RNTI), the DCI indicating a second value of the time offset larger than the first value; and
transmitting, to the terminal, a paging message on a PDSCH according to the second value.
5 . The method of claim 4 , further comprising transmitting, to the terminal, system information including the first value.
6 . The method of claim 4 ,
wherein the PDSCH including the paging message is transmitted after the PDCCH associated with the paging is processed in the terminal.
7 . A terminal in a wireless communication system, the terminal comprising:
a transceiver; and
a controller configured to:
receive, from a base station, system information including an indicator enabling a cross-slot scheduling for a paging,
determine whether the terminal supports the cross-slot scheduling for the paging,
identify a first value of a time offset between a physical downlink control channel (PDCCH) slot and a physical downlink shared channel (PDSCH) slot, the first value being predetermined,
receive, from the base station via the transceiver, downlink control information (DCI) on a PDCCH associated with a paging radio network temporary identifier (P-RNTI), the DCI indicating a second value of the time offset larger than the first value, and
receive, from the base station via the transceiver, a paging message on a PDSCH based on the second value.
8 . The terminal of claim 7 , wherein, for identifying the first value, the controller is further configured to:
receive, from the base station via the transceiver, system information including the first value, and
identify the first value included in the received system information.
9 . The terminal of claim 7 , wherein the PDSCH including the paging message is received after the PDCCH associated with the paging is processed.
10 . A base station in a wireless communication system, the base station comprising:
a transceiver; and
a controller configured to:
identify a first value of a time offset between a physical downlink control channel (PDCCH) slot and a physical downlink shared channel (PDSCH) slot, wherein the first value is predetermined,
transmit, to a terminal, system information including an indicator associated with a cross-slot scheduling for a paging,
transmit, to the terminal via the transceiver, downlink control information (DCI) on a PDCCH associated with a paging radio network temporary identifier (P-RNTI), the DCI indicating a second value of the time offset larger than the first value and,
transmit, to the terminal via the transceiver, a paging message on a PDSCH according to the second value.
11 . The base station of claim 10 , wherein the controller is further configured to transmit, to the terminal via the transceiver, system information including the first value.
12 . The base station of claim 10 , wherein the PDSCH including the paging message is transmitted after the PDCCH associated with the paging is processed in the terminal.
