Method and device for performing paging in mobile communication system
The present disclosure relates to a communication technique for combining, with an IoT technology, 5G communication system for supporting a data transmission rate higher than that of 4G systems, and to a system thereof. The present disclosure may be applied to intelligent services (e.g., a smart home, a smart building, a smart city, a smart car or connected car, healthcare, digital education, retail business, security and safety-related service, etc.), based on a 5G communication technology and an IoT-related technology. An embodiment of the present invention relates to a method and device for paging a terminal by using a beam antenna.
1. A method performed by a base station in a wireless communication system, the method comprising:
transmitting, to a terminal, system information including information related to beams;
identifying a paging occasion for transmitting a paging to the terminal, wherein the paging occasion is a set of time slots; and
transmitting, to the terminal, a same paging repeatedly through all transmission beams based on the paging occasion,
wherein the paging occasion is identified by the terminal,
wherein the set of time slots is related with a number of beams,
wherein the number of beams is determined according to the information related to beams included in the system information, and
wherein each of the time slots in the paging occasion corresponds to each of the beams.
2. The method of claim 1 ,
wherein a paging frame is identified based on an identifier of the terminal,
wherein the paging occasion is identified based on an identifier of the terminal, and
wherein the paging frame comprises one or paging occasions.
3. The method of claim 1 ,
wherein a synchronization signal is actually transmitted on the beams during a specific unit.
4. A method performed by a terminal in a wireless communication system, the method comprising:
receiving, from a base station, system information including information related to beams;
identifying a paging occasion, wherein the paging occasion is a set of time slots; and
monitoring a paging based on the paging occasion,
wherein the set of time slots is related with a number of beams,
wherein the number of beams is determined according to the information related to beams included in the system information,
wherein each of the time slots in the paging occasion corresponds to each of the beams, and
wherein a same paging is received repeatedly based on the number of beams.
5. The method of claim 4 , further comprising:
identifying a paging frame based on an identifier of the terminal,
wherein the paging occasion is identified based on the identifier of the terminal, and
wherein the paging frame comprises one or paging occasions.
6. The method of claim 4 , wherein a synchronization signal is actually transmitted on the beams during a specific unit.
7. A base station in a wireless communication system, the base station comprising:
a transceiver; and
a controller configured to:
control the transceiver to transmit, to a terminal, system information including information related to beams,
identify a paging occasion for transmitting a paging to the terminal, wherein the paging occasion is a set of time slots, and
control the transceiver to transmit, to the terminal, a same paging repeatedly through all transmission beams based on the paging occasion,
wherein the paging occasion is identified by the terminal,
wherein the set of time slots is related with a number of beams,
wherein the number of beams is determined according to the information related to beams included in the system information, and
wherein each of the time slots in the paging occasion corresponds to each of the beams.
8. The base station of claim 7 , wherein a paging frame is identified based on an identifier of the terminal,
wherein the paging occasion is identified based on the identifier of the terminal, and
wherein the paging frame comprises one or paging occasions.
9. The base station of claim 7 , wherein a synchronization signal is actually transmitted on the beams during a specific unit.
10. A terminal in a wireless communication system, the terminal comprising:
a transceiver; and
a controller configured to:
control the transceiver to receive, from a base station, system information including information related to beams,
identify a paging occasion, wherein the paging occasion is a set of time slots, and
monitor a paging based on the paging occasion,
wherein the set of time slots is related with a number of beams,
wherein the number of beams is determined according to the information related to beams included in the system information,
wherein each of the time slots in the paging occasion corresponds to each of the beams, and
wherein a same paging is received repeatedly based on the number of beams.
11. The terminal of claim 10 , wherein the controller is further configured to:
identify a paging frame based on an identifier of the terminal,
wherein the paging occasion is identified based on the identifier of the terminal, and
wherein the paging frame comprises one or paging occasions.
12. The method of claim 4 , further comprising:
selecting beams corresponding to at least one of the beams, and
receiving the paging in beams corresponding to the selected beams.
13. The terminal of claim 10 , wherein a synchronization signal is actually transmitted on the beams during a specific unit.
14. The terminal of claim 10 , wherein the controller is further configured to select beams corresponding to at least one of the beams and control the transceiver to receive the paging in the selected beams.
