Methods and devices for resource allocation for control resource region

A method, comprising:

• receiving resource allocation information indicating resources allocated to a control resource region;
• and
• determining a plurality of resource units allocated to the control resource region in a bandwidth part (BWP) based on the resource allocation information,
• wherein each of the plurality of resource units contains 6 resource blocks, and the plurality of resource units allocated to the control resource region belong to at least one resource segment, wherein first resource blocks not contained in the plurality of resource units are distributed in the BWP to divide second resource blocks in the BWP into a plurality of resource segments each containing a plurality of resource units.

A network device, comprising:

• a transceiver;
• a processor coupled to the transceiver and configured to:
• transmit resource allocation information indicating a plurality of resource units allocated to a control resource region,
• wherein each of the plurality of resource units contains 6 resource blocks, and the plurality of resource units allocated to the control resource region belong to at least one resource segment, wherein first resource blocks not contained in the plurality of resource units are distributed in a bandwidth part (BWP) to divide second resource blocks in the BWP into a plurality of resource segments each containing a plurality of resource units.

A terminal device, comprising:

• a transceiver configured to:
• receive resource allocation information indicating resources allocated to a control resource region;
• a processor configured to:
• determine a plurality of resource units allocated to the control resource region in a bandwidth part (BWP) based on the resource allocation information,
• wherein each of the plurality of resource units contains 6 resource blocks, and the plurality of resource units allocated to the control resource region belong to at least one resource segment, wherein first resource blocks not contained in the plurality of resource units are distributed in the BWP to divide second resource blocks in the BWP into a plurality of resource segments each containing a plurality of resource units.

A method performed by a terminal device, comprising:

• receiving resource allocation information for a control resource set (CORESET) in a bandwidth part (BWP), the resource allocation information indicating a plurality of resource units allocated for the CORESET, wherein the BWP further comprises a plurality of resource blocks not for the CORESET, and wherein the plurality of resource blocks divides the BWP into a plurality of resource segments each containing a plurality of resource units;
• and
• receiving downlink control information based on the resource allocation information,
• wherein each of the plurality of resource units contains 6 resource blocks.
