Abstract: A user equipment (UE) may report physical uplink control channel (PUCCH) group capabilities to a network. The UE receives a request from a network for radio access capability information and reports whether a single PUCCH group having a plurality of component carriers (CC) using more than two numerologies across the CCs is supported. The UE may also receive a request from a network for radio access capability information and report whether a PUCCH group having a plurality of CC across multiple frequency bands is supported, wherein the report is configured per band combination (BC). The UE may also receive a request from a network for radio access capability information and report support for a PUCCH location configuration for a PUCCH group having a plurality of CC across multiple frequency bands, the PUCCH location configuration indicating which bands in a band combination (BC) may be used for the PUCCH.

Abstract: Apparatuses, systems, and methods for providing an enhancement for PUCCH and Cell Grouping Capability for NR-CA and NR-DC. A wireless device may transmit, to a base station, a Physical Uplink Control Channel (PUCCH) capability report comprising at least one of PUCCH grouping capability information and a PUCCH location capability information.

Abstract: An apparatus of user equipment (UE) includes processing circuitry coupled to a memory, where to configure the UE for dynamic transmit power adjustment, the processing circuitry is to decode baseband configuration information received from a base station. The baseband configuration information including at least a modulation and coding scheme (MCS), resource block (RB) allocation, and carrier assignment for uplink (UL) transmission and downlink (DL) reception. A communication mode is selected based on the baseband configuration information. An additional maximum power reduction (A-MPR) is determined based on the baseband configuration information and the selected communication mode. UL data is encoded for transmission to the base station via the selected communication mode and using transmit power adjusted based on the determined A-MPR. New signaling enhancements between the UE and the network (on a Uu interface) and between two UEs (on a PC5 sidelink interface) are also disclosed.
