Abstract
Embodiments of the present disclosure relate to method and apparatus for secondary cell dormancy indication. According to some embodiments of the disclosure, a UE may: receive, from a BS, a signaling configuring a first set of cells for multi-cell scheduling by a DCI format and CRC of the DCI format is scrambled by a C-RNTI or an MCS-C-RNTI of the UE; receive the DCI format from the BS; determine whether a set of fields in the DCI format is repurposed for indicating secondary cell dormancy for each secondary cell of the UE, wherein a first bit of the set of fields corresponds to a first secondary cell of the UE; and switch to a dormant BWP of the first secondary cell of the UE in response to the first bit indicating dormancy for the first secondary cell.

A user equipment (UE) for wireless communication, comprising:
- at least one memory;
- and
- at least one processor coupled with the at least one memory and configured to cause the UE to:
- receive, from a base station (BS), a signaling configuring a first set of cells for multi-cell scheduling by a downlink control information (DCI) format and a cyclic redundancy check (CRC) of the DCI format is scrambled by a cell-radio network temporary identifier (C-RNTI) or a modulation and coding scheme C-RNTI (MCS-C-RNTI) of the UE;
- receive the DCI format from the BS;
- determine whether a set of fields in the DCI format is repurposed for indicating secondary cell dormancy for each secondary cell of the UE, wherein a first bit of the set of fields corresponds to a first secondary cell of the UE;
- and
- switch to a dormant bandwidth part (BWP) of the first secondary cell of the UE in response to the first bit indicating the secondary cell dormancy for the first secondary cell.
A base station (BS) for wireless communication, comprising:
- at least one memory;
- and
- at least one processor coupled with the at least one memory and configured to cause the BS to:
- transmit, to a user equipment (UE), a signaling configuring a first set of cells for multi-cell scheduling by a downlink control information (DCI) format and a cyclic redundancy check (CRC) of the DCI format is scrambled by a cell-radio network temporary identifier (C-RNTI) or a modulation and coding scheme C-RNTI (MCS-C-RNTI) of the UE;
- and
- transmit the DCI format to the UE, wherein the DCI format indicates whether a set of fields in the DCI format is repurposed for indicating secondary cell dormancy for each secondary cell of the UE, and a first bit of the set of fields corresponds to a first secondary cell of the UE.
A processor for wireless communication, comprising:
- at least one controller coupled with at least one memory and configured to cause the processor to:
- receive, from a base station (BS), a signaling configuring a first set of cells for multi-cell scheduling by a downlink control information (DCI) format and a cyclic redundancy check (CRC) of the DCI format is scrambled by a cell-radio network temporary identifier (C-RNTI) or a modulation and coding scheme C-RNTI (MCS-C-RNTI) of a user equipment (UE);
- receive the DCI format from the BS;
- determine whether a set of fields in the DCI format is repurposed for indicating secondary cell dormancy for each secondary cell of the UE, wherein a first bit of the set of fields corresponds to a first secondary cell of the UE;
- and
- switch to a dormant bandwidth part (BWP) of the first secondary cell of the UE in response to the first bit indicating the secondary cell dormancy for the first secondary cell.
A method performed by a user equipment (UE), the method comprising:
- receiving, from a base station (BS), a signaling configuring a first set of cells for multi-cell scheduling by a downlink control information (DCI) format and a cyclic redundancy check (CRC) of the DCI format is scrambled by a cell-radio network temporary identifier (C-RNTI) or a modulation and coding scheme C-RNTI (MCS-C-RNTI) of a user equipment (UE);
- receiving the DCI format from the BS;
- determining whether a set of fields in the DCI format is repurposed for indicating secondary cell dormancy for each secondary cell of the UE, wherein a first bit of the set of fields corresponds to a first secondary cell of the UE;
- and
- switching to a dormant bandwidth part (BWP) of the first secondary cell of the UE in response to the first bit indicating the secondary cell dormancy for the first secondary cell.
