    摘要: A user equipment (UE) configured for operating in a fifth-generation (5G) new radio (NR) network may monitor search space sets for a number of physical downlink control channel (PDCCH) candidates within a number of non-overlapped control-channel elements (CCEs) for a primary cell (PCell). The number of PDCCH candidates and the number of non-overlapped CCEs may include PDCCH candidates and non-overlapped CCEs on a scheduling secondary cell (SCell). The scheduling SCell may be an SCell that schedules a transmission on the PCell. The UE may decode one or more of the PDCCH candidates on the scheduling SCell for a downlink control information (DCI) format which may schedule a physical downlink shared channel (PDSCH) transmission and/or a physical uplink shared channel (PUSCH) transmission of the PCell.

    摘要: A user equipment (UE) for operation in a fifth-generation new radio (5G NR) network may be configured with two or more secondary cells (SCells) of a group of SCells. In these embodiments, the UE may monitor a physical downlink control channel (PDCCH) for detection of a downlink control information (DCI) format 1_1. The UE may interpret the DCI format 1_1 as indicating SCell dormancy, rather than scheduling a physical downlink shared channel (PDSCH) reception, if the UE is configured with resourceAllocationType1 and if all bits of a frequency domain resource assignment field in the DCI format 1_1 are equal to 1. For SCell dormancy, the UE may interpret fields of the DCI format 1_1 as a bitmap for SCell dormancy indication and either activate or deactivate a downlink bandwidth part (DL BWP) for an SCell of the group of configured SCells when indicated by the bitmap.
