Abstract

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.Embodiments disclosed herein provide a method for managing a resource in a wireless communication system. The method includes allocating, by a base station, the resource for a data transmission from a User Equipment (UE) by indicating at least one bandwidth part in a total bandwidth supported by the UE. The resource is further allocated by indicating a Physical Downlink Control Channel (PDCCH) and a Physical Downlink Shared Control Channel (PDSCH) according to a configured subcarrier spacing and a CP length within the at least one bandwidth part, and by indicating an allocation of Resource Blocks (RBs) within the at least one bandwidth part.

First claim

What is claimed is:

1. A method performed by a base station in a wireless communication system, the method comprising:
transmitting, to a user equipment (UE), a first message comprising information on at least one bandwidth part (BWP) including first configuration information on a Physical Downlink Control Channel (PDCCH) and second configuration information on a Physical Downlink Shared Control Channel (PDSCH) via Radio Resource Control (RRC); and
transmitting, to the UE, a second message comprising downlink control information (DCI) to be used for an BWP activation and including resource allocation information for scheduling of the PDSCH,
wherein resource blocks (RBs) are identified by the resource allocation information, and
wherein the at least one bandwidth part is associated with a subcarrier spacing and a cyclic prefix (CP) length.

2. The method of claim 1 , wherein a resource allocation (RA), type of the RBs is identified based on a flag included in the transmitted DCI.

3. The method of claim 1 , wherein a size of groups of the RBs is determined based on the information on at least one bandwidth part.

4. The method of claim 1 , wherein the RBs are mapping from a carrier center.

5. A method performed by a User Equipment (UE) in a wireless communication system, the method comprising:
receiving, from a base station, information on at least one bandwidth part (BWP) including first configuration information on a Physical Downlink Control Channel (PDCCH), and second configuration information on a Physical Downlink Shared Control Channel (PDSCH) via Radio Resource Control (RRC),
receiving, from the base station, downlink control information (DCI) to be used for an BWP activation and including resource allocation information for scheduling of the PDSCH, and
identifying resource blocks (RBs) by the resource allocation information,
wherein the at least one bandwidth part is associated with a subcarrier spacing and a cyclic prefix (CP) length.

6. The method of claim 5 , wherein a resource allocation (RA), type of the RBs is identified based on a flag included in the received DCI.

7. The method of claim 5 , wherein a size of groups of the RBs is determined based on the information on at least one bandwidth part.

8. The method of claim 5 , wherein the RBs are mapping from a carrier center.

9. A base station in a wireless communication system, the base station comprising:
a memory;
a processor; and
a controller communicatively coupled to the memory and the processor, the controller configured to:
transmit, to a user equipment (UE), a first message comprising information on at least one bandwidth part (BWP) including first configuration information on a Physical Downlink Control Channel (PDCCH) and second configuration information on a Physical Downlink Shared Control Channel (PDSCH) via Radio Resource Control (RRC), and
transmit, to the UE, a second message comprising downlink control information (DCI) to be used for an BWP activation and including resource allocation information for scheduling of the PDSCH,

wherein resource blocks (RBs) are identified by the resource allocation information, and
wherein the at least one bandwidth part is associated with a subcarrier spacing and a cyclic prefix (CP) length.

10. The base station of claim 9 , wherein a resource allocation (RA), type of the RBs is identified based on a flag included in the transmitted DCI.

11. The base station of claim 9 , wherein a size of groups of the RBs is determined based on the information on at least one bandwidth part.

12. The base station of claim 9 , wherein the RBs are mapping from a carrier center.

13. A user equipment (UE) in a wireless communication system, the UE comprising:
a memory;
a processor; and
a controller communicatively coupled to the memory and the processor, the controller configured to:
receive, from a base station, information on at least one bandwidth part (BWP) including first configuration information on a Physical Downlink Control Channel (PDCCH), and second configuration information on a Physical Downlink Shared Control Channel (PDSCH) via Radio Resource Control (RRC),
receive, from the base station, downlink control information (DCI) to be used for an BWP activation and including resource allocation information for scheduling of the PDSCH, and
identify resource blocks (RBs) by the resource allocation information,

wherein the at least one bandwidth part is associated with a subcarrier spacing and a cyclic prefix (CP) length.

14. The UE of claim 13 , wherein a resource allocation (RA), type of the RBs is identified based on a flag included in the received DCI.

15. The UE of claim 13 , wherein a size of groups of the RBs is determined based on the information on at least one bandwidth part.

16. The UE of claim 13 , wherein the RBs are mapping from a carrier center.
