Abstract: Provided is a method for a user equipment (UE). The UE obtains a physical uplink control channel (PUCCH) secondary cell (SCell) activation command from a primary cell (PCell) or primary secondary-cell-group cell (PSCell). The PUCCH SCell activation command is used for an PUCCH SCell activation of a target PUCCH SCell for the UE. The UE performs PUCCH SCell activation operations associated with a valid timing advance (TA) and the PUCCH SCell activation command. TA is considered to be a valid TA when the TA meets a preset criterion. The UE generates a channel state information (CSI) report for transmission to at least one of the PCell, PSCell and the target PUCCH SCell. The CSI report indicates that the PUCCH SCell activation is completed.

Abstract: Provided is a method for a user equipment. The method includes starting performing a handover (HO) with a target Primary Secondary Cell (PSCell) in response to receiving an HO command instructing the HO with the target PSCell, wherein the HO with the target PSCell comprises target PSCell addition/change, and performing the target PSCell addition/change in response to receiving a trigger message from a target Primary Cell (PCell) or sending a trigger message to the target PCell, wherein the trigger message is a message transmitted between the UE and the target PCell during the HO with the target PSCell.

Abstract: An apparatus may receive a media access control (MAC) control element (CE) from a base station (BS) indicating a secondary cell (SCell) to be activated in an unlicensed band. The apparatus may initiate a timer with an end value in response to receiving the MAC CE and may further adjust a radio-frequency (RF) chain from a first state to a second state corresponding to the SCell to be activated. The apparatus may determine, based on measurements of one or more synchronization signal blocks (SSBs) transmitted from the BS indicating one or more listen before talk (LBT) failures corresponding to the SCell, one or more failed SSB transmissions corresponding to the SCell. Accordingly, the apparatus may readjust, in response to expiry of the timer, the RF chain from the second state to the first state and receive one or more additional SSBs in the first state.

Abstract: Systems, devices, and techniques for wireless communications based on one or more transmission configuration indicator (TCI) states are described. A described technique performed by a user equipment (UE) includes receiving a first downlink channel based on a current TCI state; receiving a physical downlink shared channel (PDSCH) in a first slot, the PDSCH carrying a radio resource control (RRC) activation command in the first slot, the RRC activation command indicating a switch to a target TCI state; waiting until an end of a switching period triggered by the RRC activation command to use the target TCI state, the switching period being based on a RRC processing delay; and receiving, based on the end of the switching period, a second downlink channel based on the target TCI state in a second slot.

Abstract: Systems, devices, and techniques for measuring and reporting cross-link interference (CLI) are described. A described technique includes determining, by a first wireless device, whether to perform a CLI measurement; determining a quantity of activated transmission configuration indicator (TCI) states associated with a second wireless device; performing the CLI measurement based on the quantity of activated TCI states; and transmitting a CLI report in response to the CLI measurement.

Abstract: A user equipment (UE) device is configured for performing a signal measurement for wireless communication in a new radio (NR) network. The UE is configured to determine a frequency range (FR) of a serving cell configured to send a signal that is measured by the UE using a signal measurement. The UE configures a measurement gap (MG) pattern to perform the signal measurement. Configuring the measurement gap includes determining that the frequency range of the serving cell includes frequencies of a second frequency range (FR2), determining that a measurement object (MO) configuration for the FR2 is available, setting a measurement gap repetition periodicity (MGRP) value for the signal measurement, and setting a measurement gap length (MGL) value for the signal measurement. The UE performs a signal measurement using the MGRP value and the MGL value.
