Abstract: A user equipment including a transceiver and a processor is configured to receive, from a base station and via the transceiver, a set of resource indicators identifying a set of beams for transmission of data between the base station and the UE. The processor is also configured to perform a number of power management maximum power reduction (P-MPR) measurements for a first subset of resources, and a number of layer-1 reference signal received power (L1-RSRP) measurements for a second subset of resources. The processor is also configured to transmit, to the base station, a number of P-MPR reports and a number of L1-RSRP reports corresponding to the number of P-MPR and L1-RSRP measurements, respectively, and receive data in a downlink direction from the base station, over a beam of the set of beams at least partly in response to the number of P-MPR reports and L1-RSRP reports.

Abstract: Aspects are described for a user equipment (UE) comprising two or more transceivers configured to enable wireless communication with a first base station, and a processor communicatively coupled to the two or more transceivers. The processor is configured to measure a first reference signal and a second reference signal during a measuring period to determine a first measuring result of the first reference signal and a second measuring result of the second reference signal. The processor is further configured to generate one or more reports that include the first measuring result and the second measuring result, wherein the one or more reports indicate that the first measuring result is associated with the second measuring result in time. The processor is further configured to transmit the one or more reports to the first base station.

Abstract: Some aspects relate to apparatuses and methods for a wireless system implementing mechanisms to transmit a measurement report using physical layer (L1) carrying a sounding reference signal (SRS) reference signal received power (SRS-RSRP) measurement to provide an indication of cross link interference (CLI) between a first user equipment (UE) and a second UE. The first UE can determine a channel state information (CSI) configuration received from the base station; and configure, based on the CSI configuration, a channel measurement resource (CMR) to include a SRS received from the second UE. The first UE can measure the SRS to obtain a SRS-RSRP measurement, generate a measurement report having the SRS-RSRP measurement, and transmit the measurement report to the base station using L1.

Abstract: A user equipment (UE) is configured to perform measurements during two or more measurement gaps (MGs). The UE receives a MG configuration, wherein the MG configuration includes multiple MGs and MG conflict resolution information, determines whether a conflict exists between two or more of the MGs, selects at least one of the two or more MGs that have the conflict based on the MG conflict resolution information and performs signal measurements during the selected at least one of the two or more MGs that have the conflict.

Abstract: A user equipment (UE) is provided to select an uplink transmission beam to communicate with a base station in a secondary cell of a carrier aggregation (CA) scheme. The UE can communicate with a first base station in a primary cell (PCell), and receive a command from the wireless network to activate a physical uplink control channel (PUCCH) transmission to a second base station in a secondary cell (SCell). The second base station can be in a being-activated state. The UE can determine whether an uplink spatial relation configuration is provided to the UE, and determine whether the UE supports beam correspondence. Based on the determinations, the UE can select an uplink transmission beam for the PUCCH transmission to the second base station.

Abstract: A user equipment (UE) is configured to change a transmission configuration indicator (TCI) state. The receives, from the base station, a network flag indicating a transmission configuration indicator (TCI) state change configuration for the network, determines a time span for continuing to use a current TCI state prior to switching to a new TCI state based on the network flag and switches to the new TCI state after the time span.
