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: A user equipment (UE) may be configured to perform layer 1 (L1) measurement procedures and layer 3 (L3) measurement procedures. The UE configures a channel state information-reference signal (CSI-RS) layer 3 (L3) measurement window, identifies a collision between a layer 1 (L1) measurement operation and a L3 measurement operation and omits at least one L1 measurement in response to identifying the collision.

Abstract: Techniques discussed herein can facilitate inter-cell interference mitigation. One example aspect is a user equipment (UE), configured to receive a network assistance indication associated with an interfering signal, where the interfering signal interferes with a physical downlink shared channel (PDSCH) transmission. A time resource allocation of the interfering signal is different than a time resource allocation of the PDSCH transmission. The UE is further configured to determine an interference and noise covariance estimation mechanism based on the network assistance indication then perform interference and noise covariance estimation based on the noise covariance estimation mechanism. The UE is further configured to perform mitigation of the interfering signal using a mitigation mechanism based on the interference and noise covariance estimation.

Abstract: Apparatus and method are provided for a user equipment (UE) to perform measurement operations for a handover procedure including target NR Primary Secondary Cell (PSCell) change or addition. The measurements of a target PSCell are performed in accordance with a synchronization signal/physical broadcast channel (SS/PBCH) block measurement time configuration (SMTC) included in a measurement object received from a base station (BS). A source primary cell (PCell) is used for reference timing of the SMTC if the measurement object is configured by the source PCell on same frequency and subcarrier spacing of the target PSCell. A source PSCell is used for reference timing of the SMTC if the measurement object is configured by the source PSCell on same frequency and subcarrier spacing of the target PSCell.

Abstract: A UE for a 5G system is to perform a measurement during a network controlled small gap (NCSG). The NCSG includes a first visible interruption length (VIL1), a measurement length (ML), a second visible interruption length (VIL2), and a visible interruption repetition period (VIRP). A UE capability indicates a length of one or both the VIL1 and the VIL2. NCSG pattern information provides the NCSG for the UE, in which the VIL1 and the VIL2 indicate when the UE is not expected to transmit and receive data on a serving carrier, the ML indicates when the UE is expected to transmit and receive data on the serving carrier, and the VIRP indicates a period in which to repeat the NCSG.

Abstract: Layer 2 handling during a cell change procedure includes decoding an RRC reconfiguration message received from a first cell. The RRC reconfiguration message includes a Layer 1 (L1) configuration corresponding to a second cell. The first cell and the second cell share an SDAP entity, a PDCP entity, an RLC entity, and a MAC entity. The first cell and the second cell have a separate L1 entity. In response to decoding the RRC reconfiguration message, the L1 configuration corresponding to the second cell is stored. A cell change message received from the first cell is decoded. The cell change message indicates that a cell change from the first cell to the second cell is to be performed. The stored L1 configuration corresponding to the second cell is applied for data transmission and reception associated with the second cell. A cell change to the second cell is initiated.

Abstract: The present application relates to devices and components including apparatus, systems, and methods to perform a switch of a TCI state from a serving cell to a neighbor cell. A UE determines whether the state of the neighbor cell is known or unknown and whether the neighbor cell's TCI state is known or unknown. The total delay time to perform the TCI state switch can impacted by this the known/unknown statuses. Other factors can also contribute to the total delay time. The UE may also signal its capability to monitor the TCI state of the neighbor cell and its capability to switch to such a TCI state.
