Abstract: Systems and methods for interlace PUCCH transmission in 5G networks are described. The gNB sends an RRC message to a UE. The RRC message provides one or more PUCCH interlace allocations within a BW. Each PUCCH interlace allocation has a PUCCH format for each PUCCH interlace. Each PUCCH format contains a different PUCCH interlace index. The UE sends a PUCCH interlace in the BWP based on the PUCCH interlace allocation. A PUCCH in the allocated PUCCH interlace has a cyclic shift that is dependent on a resource block number in the allocated PUCCH interlace within the BWP.

Abstract: 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.
