Abstract: Reporting potential impacts of sounding reference signal-switching (SRS-switching) to a base station may include determining that SRS-switching is to be performed by a UE. Based on determining that SRS-switching is to be performed, potential impacts to one or more of a plurality of radio access technologies (RATs) caused by performing SRS-switching while sharing radio frequency (RF) front-ends (RFFE) between at least a subset of the plurality of RATs may be processed. The potential impacts may comprise at least one of transmit-blanking (Tx-blanking) and receive-blanking (Rx-blanking) associated with one or more of the subset of RATs. A communication that indicates the potential impacts of SRS-switching may be encoded for transmission to a base station. The base station may also provide priority configurations for determining how to handle Tx-blanking, Rx-blanking, and SRS-skipping associated with SRS-switching.

Abstract: A base station and a user equipment (UE) may exchange messages to perform a Random Access Channel (RACH) procedure. The UE performs measurements on a plurality of signal synchronization blocks (SSBs), selects M physical random access channel (PRACH) groups based on one or more of the measured SSBs satisfying a predetermined threshold, provides the measurements for the M PRACH groups to a base station in an initial access transmission for a RACH procedure and monitors for a random access response (RAR) message based on a repetition number for the RAR message indicated by the base station.

Abstract: A user equipment (UE) performs a multi-level Downlink Control Information (DCI) monitoring operation. The UE monitors an Anchor-search space set (SSS) of a first resource block (RB) set for downlink control information (DCI) and, when the Anchor-SSS includes DCI, monitors at least one Subordinate-SSS of a second RB set based on at least the DCI detected on the Anchor-SSS.

Abstract: This disclosure relates to techniques for performing wireless communications by rapidly moving user equipment device in communication with a network. The UE may adapt communication techniques in response to the UE's motion. For example, reference signals may be transmitted by the UE to additional transmission and reception points and/or using different configurations. Similarly, the UE may receive reference signals from additional transmission and reception points.

Abstract: A base station is configured to receive channel state information (CSI) from a user equipment (UE). The base station transmits configuration information including one or more interference measurement resources (IMRs) allocated for measurement by the UE, receives a reference CSI report from the UE, receives a new CSI report including interference and noise power fluctuation feedback from the UE and selects a modulation and coding scheme (MCS) for the UE based on at least the interference and noise power fluctuation feedback and the reference CSI report.

Abstract: A user equipment (UE), or other network device (e.g., next generation NodeB (gNB)) component can operate to process or configure a search space information element (IE) that is configured with at least one of: a transmission configuration indicator (TCI) state identifier (ID) of a TCI, or a physical downlink control channel (PDCCH) repetition field indicating a number of PDCCH repetitions, or a number of UE-specific search space (USS) repetitions for the PDCCH. A UE can perform search space set group (SSSG) beam switching based on one or more TCI states and at least one of: a search space set (SSS) index, an SSSG index, or a beam switching request (BSR) field value. A physical downlink control channel (PDCCH) associated with the search space can be transmitted for beam switching according to a search space information element.

Abstract: This disclosure describes the following enhancement to improve the PDCCH reliability: PDCCH aggregation and multi-beam PDCCH reception for a 5G wireless communication system. The disclosed techniques entail obtaining repeated PDCCH by processing a PDCCH-Config, ControlResourceSet, or SearchSpace configuration parameter including an information element (IE) indicating a number of consecutive slots in which the PDCCH is repeated. In another embodiment, a gNB generates the PDCCH-Config, ControlResourceSet, or SearchSpace configuration parameter for configuring a UE to receive the repeated PDCCH and employ the multi-beam PDCCH reception.
