The present disclosure relates to a pre-5th-generation (5G) or 5G communication system to be provided for supporting higher data rates beyond 4th-generation (4G) communication system such as long term evolution (LTE). A terminal in a wireless communication system is provided. The terminal includes a transceiver; and at least one processor configured to: receive, from a base station, configuration information for a bandwidth part, and receive, from the base station, information for a resource configuration within the bandwidth part.
1. A terminal in a wireless communication system comprising:
a transceiver; and
at least one processor configured to:
receive, from a base station via radio resource control (RRC) signaling, a configured scheduling-radio network temporary identifier (CS-RNTI) and information on a first bandwidth part (BWP), wherein the first BWP is configured with a semi-persistent scheduling (SPS) configuration, the SPS configuration including a periodicity associated with the first BWP; and
perform a first SPS communication on the first BWP based on the CS-RNTI and the SPS configuration;
based on identifying at least one first event associated with a switching of an active BWP to a second BWP, suspend the first SPS communication on the first BWP and perform a communication on the second BWP; and
based on identifying at least one second event associated with the switching of the active BWP to the first BWP, perform a second SPS communication on the first BWP according to the CS-RNTI and the SPS configuration,
wherein the second BWP is activated and the first BWP is deactivated according to the at least one first event, and
wherein the second BWP is deactivated and the first BWP is activated according to the at least one second event.
2. The terminal of claim 1 , wherein the information on the first BWP comprises a downlink BWP parameter or an uplink BWP parameter.
3. The terminal of claim 2 , wherein the downlink BWP parameter comprises a downlink SPS configuration per serving cell and per BWP, and wherein the uplink BWP parameter comprises an uplink SPS configuration per serving cell and per BWP.
4. The terminal of claim 1 , wherein the SPS configuration further comprises a number of hybrid automatic repeat request (HARQ) processes for the first BWP.
5. The terminal of claim 1 , wherein the at least one first event or the at least one second event comprises:
a reception of a RRC message indicating a change of the active BWP;
a reception of control information indicating a change of the active BWP; and
an expiration of a timer associated to the active BWP.
6. The terminal of claim 1 ,
wherein the at least one processor is further configured to receive, from the base station, information on a third BWP,
wherein the CS-RNTI is configured to the first BWP and the third BWP, and
wherein the third BWP is configured with a SPS configuration including a periodicity associated with the third BWP.
7. The terminal of claim 1 ,
wherein the second SPS communication on the first BWP starts on a symbol, and
wherein the symbol is determined based on a time offset of the SPS configuration.
8. A base station in a wireless communication system comprising:
a transceiver; and
at least one processor configured to:
transmit, to a terminal via radio resource control (RRC) signaling, a configured scheduling- radio network temporary identifier (CS-RNTI) and information on a first bandwidth part (BWP), wherein the first BWP is configured with a semi persistent scheduling (SPS) configuration, the SPS configuration including a periodicity associated with the first BWP;
perform a first SPS communication on the first BWP based on the CS-RNTI and the SPS configuration;
based on identifying at least one first event associated with a switching of an active BWP to a second BWP, suspend the first SPS communication on the first BWP and perform a communication on the second BWP; and
based on identifying at least one second event associated with the switching of the active BWP to the first BWP, perform a second SPS communication on the first BWP according to the CS-RNTI and the SPS configuration,
wherein the second BWP is activated, and the first BWP is deactivated according to the at least one first event, and
wherein the second BWP is deactivated and the first BWP is activated according to the at least one second event.
9. The base station of claim 8 ,
wherein the information on the first BWP comprises a downlink BWP parameter or an uplink BWP parameter.
10. The base station of claim 9 , wherein the downlink BWP parameter comprises a downlink SPS resource configuration per serving cell and per BWP, and
wherein the uplink BWP parameter comprises an uplink SPS resource configuration per serving cell and per BWP.
11. The base station of claim 8 , wherein the SPS configuration further comprises a number of hybrid automatic repeat request (HARQ) processes for the first BWP.
12. The base station of claim 8 ,
wherein the at least one first event or the at least one second event comprises:
a reception of a RRC message indicating a change of the active BWP;
a reception of control information indicating a change of the active BWP; and
an expiration of a timer associated to the active BWP.
13. The base station of claim 8 ,
wherein the at least one processor is further configured to transmit, to the terminal, information on a third BWP,
wherein the CS-RNTI is configured to the first BWP and a third BWP, and
wherein the third BWP is configured with a SPS configuration including a periodicity associated with the third BWP.
14. The base station of claim 8 ,
wherein the second SPS communication on a first BWP starts on a symbol, and
wherein the symbol is determined based on a time offset of the SPS configuration.
