Bandwidth part configurations for single carrier wideband operations
The present disclosure relates to a communication method and system for converging a 5 th -Generation (5G) communication system for supporting higher data rates beyond a 4 th -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.
1. A method performed by a base station in a wireless communication system, the method comprising:
transmitting, to a user equipment (UE), information on at least one bandwidth part, including first configuration information on a Physical Downlink Control Channel (PDCCH) and second configuration information on a Physical Downlink Shared Control Channel (PDSCH) via a radio resource control (RRC) signaling; and
transmitting, to the UE, downlink control information (DCI), including resource allocation information for scheduling of the PDSCH after transmitting the information on at least one bandwidth part,
wherein resource blocks (RBs) are identified based on the resource allocation information, and
wherein a resource allocation (RA) type of the RBs is identified based on a flag included in the transmitted DCI.
2. The method of claim 1 , wherein a size of groups of the RBs is determined based on the information on the at least one bandwidth part.
3. The method of claim 1 , wherein the RBs are mapped from a carrier center.
4. 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, including first configuration information on a Physical Downlink Control Channel (PDCCH) and second configuration information on a Physical Downlink Shared Control Channel (PDSCH) via a radio resource control (RRC) signaling;
receiving, from the base station, downlink control information (DCI), including resource allocation information for scheduling of the PDSCH after receiving the information on at least one bandwidth part; and
identifying resource blocks (RBs) based on the resource allocation information,
wherein a resource allocation (RA) type of the RBs is identified based on a flag included in the received DCI.
5. 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), information on at least one bandwidth part, including first configuration information on a Physical Downlink Control Channel (PDCCH) and second configuration information on a Physical Downlink Shared Control Channel (PDSCH) via a radio resource control (RRC) signaling, and
transmit, to the UE, downlink control information (DCI), including resource allocation information for scheduling of the PDSCH after transmitting the information on at least one bandwidth part,
wherein resource blocks (RBs) are identified based on the resource allocation information, and
wherein a resource allocation (RA) type of the RBs is identified based on a flag included in the transmitted DCI.
6. The base station of claim 5 , wherein a size of groups of the RBs is determined based on the information on the at least one bandwidth part.
7. The base station of claim 5 , wherein the RBs are mapped from a carrier center.
8. 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, including first configuration information on a Physical Downlink Control Channel (PDCCH) and second configuration information on a Physical Downlink Shared Control Channel (PDSCH) via a radio resource control (RRC) signaling,
receive, from the base station, downlink control information (DCI), including resource allocation information for scheduling of the PDSCH after receiving the information on at least one bandwidth part, and
identify resource blocks (RBs) based on the resource allocation information,
wherein a resource allocation (RA) type of the RBs is identified based on a flag included in the received DCI.
