Method and apparatus for transmitting and receiving paging and dedicated system information 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 present disclosure provides methods and apparatuses for monitoring paging and acquiring dedicated system information in a wireless communication system.
1. A method performed by a terminal in a wireless communication system, the method comprising:
receiving, from a source base station, a first radio resource control (RRC) reconfiguration message including information on a configuration for an on-demand system information block (SIB) request, wherein the information on the configuration includes a value of a prohibit timer associated with the on-demand SIB request;
transmitting, to the source base station, a first dedicated SIB request message based on the information on the configuration for the on-demand SIB request;
starting a timer T 350 with a timer value set to the value of the prohibit timer associated with the on-demand SIB request;
receiving, from the source base station, a second RRC reconfiguration message;
identifying whether the second RRC reconfiguration message includes information on a reconfiguration with synchronization for a special cell of a target base station;
stopping the timer, in case that the second RRC reconfiguration message includes the information on the reconfiguration with synchronization for the special cell of the target base station; and
transmitting, to the target base station, a second dedicated SIB request message.
2. The method of claim 1 ,
wherein the second dedicated SIB request message is transmitted, upon a random access procedure with the target base station is completed.
3. The method of claim 1 , the method further comprising:
receiving, from the target base station, at least one SIB as a response to the second dedicated SIB request message.
4. The method of claim 1 , the method further comprising:
starting the timer T 350 associated with the second dedicated SIB request message.
5. A method in a wireless communication system, the method comprising:
transmitting, by a source base station to a terminal, a first radio resource control (RRC) reconfiguration message including information on a configuration for an on-demand system information block (SIB) request, the information on the configuration for the on-demand SIB request including a value of a prohibit timer associated with the on-demand SIB request;
receiving, by the source base station from the terminal, a first dedicated SIB request message based on the information on the configuration for the on-demand SIB request;
starting, by the terminal, a timer T 350 with a timer value set to the value of the prohibit timer associated with the on-demand SIB request;
transmitting, by the source base station to the terminal, a second RRC reconfiguration message including information on a reconfiguration with synchronization for a special cell of a target base station;
stopping, by the terminal, the timer T 350 based on the second RRC reconfiguration message; and
transmitting, by the terminal to the target base station, a second dedicated SIB request message.
6. A terminal in a wireless communication system, the terminal comprising:
a transceiver; and
a controller coupled with the transceiver and configured to:
receive, from a source base station, a first radio resource control (RRC) reconfiguration message including information on a configuration for an on-demand system information block (SIB) request, wherein the information on the configuration includes a value of a prohibit timer associated with the on-demand SIB request,
transmit, to the source base station, a first dedicated SIB request message based on the information on the configuration for the on-demand SIB request,
start a timer T 350 with a timer value set to the value of the prohibit timer associated with the on-demand SIB request,
receive, from the source base station, a second RRC reconfiguration message,
identify whether the second RRC reconfiguration message includes information on a reconfiguration with synchronization for a special cell of a target base station,
stop the timer T 350 , in case that the second RRC reconfiguration message includes the information on the reconfiguration with synchronization for the special cell of the target base station, and
transmit, to the target base station, a second dedicated SIB request message.
7. The terminal of claim 6 ,
wherein the second dedicated SIB request message is transmitted, upon a random access procedure with the target base station is completed.
8. The terminal of claim 6 ,
wherein the controller is further configured to receive, from the target base station, at least one SIB as a response to the second dedicated SIB request message.
9. The terminal of claim 6 ,
wherein the controller is further configured to start the timer T 350 associated with the second dedicated SIB request message.
10. A wireless communication system comprising a terminal and a base station, wherein the base station comprises:
a transceiver; and
a controller coupled with the transceiver and configured to:
transmit, to a terminal, a first radio resource control (RRC) reconfiguration message including information on a configuration for an on-demand system information block (SIB) request, the information on the configuration for the on-demand SIB request including a value of a prohibit timer associated with the on-demand SIB request,
receive, from the terminal, a first dedicated SIB request message based on the configuration for the on-demand SIB request, and
transmit, to the terminal, a second RRC reconfiguration message including information on a reconfiguration with synchronization for a special cell of a target base station,
wherein the terminal comprises:
a transceiver; and
a controller coupled with the transceiver and configured to:
start a timer T 350 with a timer value set to the value of the prohibit timer associated with the on-demand SIB request,
stop the timer T 350 based on the second RRC reconfiguration message, and
transmit, to the target base station, a second dedicated SIB request message.
