Abstract: Embodiments of a user equipment (UE) configured for operation in a fifth generation (5G) new radio (NR) network are disclosed herein. In some embodiments, a media access control Layer (MAC) control element (CE) (MAC CE) may activate a spatial relation info for a sounding reference signal (SRS) resource for two or more indicated component carriers (CCs). The spatial relation info for the SRS resource for the two or more indicated CCs may be applied in response to the activation. The SRS resource may be transmitted in the two or more indicated CCs with a same spatial transmission filter that is used for another reference signal configured in the spatial relation info when the UE is configured with one or more SRS resource configurations and when the spatial relation info is activated.

Abstract: Embodiments of a User Equipment (UE), Next Generation Node-B (gNB) and methods of communication are generally described herein. The gNB may encode multiple candidate code-block groups to be available for a transmission in unlicensed spectrum, wherein one of the candidate code-block groups is to be transmitted based on a listen-before-talk (LBT) process. Each of the candidate code-block groups may be mapped to a different subset of channels in the unlicensed spectrum. The gNB may determine, based on one or more channel measurements, one or more of the channels that are available for the transmission. The gNB may select, as the candidate code-block group to be transmitted, a candidate code-block group for which the subset of the channels that is mapped to the selected candidate code-block group is included in the one or more channels that are available for the transmission.

Abstract: An eNodeB (eNB), user equipment (UE) and method for operating in enhanced coverage (EC) modes are generally described. The UE may receive one or more physical broadcast channel (PBCH) signals, dependent on whether the UE is in a normal coverage mode or in one of the EC modes. The PBCH signal may be combined to form a combined PBCH signal, when the UE is in an EC mode, and decoded to determine one of a plurality of sets of resource regions associated different EC modes for communication with the eNB. The signal may be scrambled using a Radio Network Temporary Identifier (RNTI) dependent on at least one of a signal type of the control signal and the EC mode. Paging and the system information block (SIB) signals in a Physical Downlink Shared Channel (PDSCH) may be decoded without decoding a physical downlink control channel (PDCCH) signal associated with the PDSCH.
