Assignee: SAMSUNG ELECTRONICS CO., LTD.
Field: Digital communication (Electrical engineering)
Classification: CPC H  Y | IPC H

Claim 10:
11. A user equipment (UE) in a communication system, the UE comprising:
a transceiver; and
a controller configured to:
receive, from a base station, configuration information of a dormant bandwidth part (BWP) for a secondary cell (SCell),
receive, from the base station, downlink control information (DCI). wherein a frequency domain resource assignment field, a modulation and coding scheme (MCS) field, a new data indicator (NDI) field, a redundancy version (RV) field, a hybrid automatic repeat request (HARQ) process number field, an antenna port field, and a demodulation reference signal (DMRS) sequence initialization field are included in the DCI, and
consider the DCI as an indication of SCell dormancy, in case that a resource allocation type corresponds to type 1 and all bits of the frequency domain resource assignment field are equal to 1,
wherein a sequence of the MCS field, the NDI field, the RV field, the HARQ process number field, the antenna port field, and the DMRS sequence initialization field is interpreted as providing a bitmap to each configured SCell,
wherein a bit of the bitmap corresponds to an SCell, and
wherein a 0 value for the bit of the bitmap indicates the dormant BWP for the SCell.
