Abstract: Devices, systems, and methods for Random Access Channel (RACH) configuration in Layer 1 (L1)/Layer 2 (L2) mobility. A user equipment (UE) may obtain a downlink (DL) Transmission Configuration Indicator (TCI) list from a first Transmission and Reception Point (TRP). The DL TCI list may include DL beam information, RACH Occasion (RO) information, and initial Bandwidth Part (BWP) information associated with each DL TCI of a plurality of DL TCIs related to the first TRP and multiple TRPs adjacent to the first TRP. The UE may receive a handover command from the first TRP via Downlink Control Information (DCI) in Li or Media Access Control (MAC) Control Element (CE) in L2. The handover command indicates a handover from the first TRP to a second TRP of the multiple TRPs for the UE, and includes a specified DL TCI related to the second TRP.

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.

The UE determines that a first uplink transmission is scheduled to overlap in time with a second uplink transmission based on a look ahead window, determines a first transmission power for the first uplink transmission, determines a second transmission power for the second uplink transmission based on the first transmission power for the first uplink transmission and performs the first uplink transmission and the second uplink transmission.

Abstract: Some aspects relate to apparatuses and methods for implementing mechanisms for performing handover, radio link monitoring (RLM), beam failure detection (BFD), and candidate beam detection (CBD) within the unlicensed spectrum when a listen-before-talk (LBT) failure occurs and/or when a user equipment (UE) performs receiving (RX) beam sweeping. For example, a UE is configured to receive a handover command to connect to a target cell. The UE is further configured to determine a search time and an interruption time uncertainty during a handover procedure initiated by the handover command and in response to a LBT failure or the UE performing a beam sweeping operation. The UE can further determine a handover delay based on the search time and the interruption time uncertainty. In response to a time period for performing the handover procedure exceeding the handover delay, the UE can cease the handover procedure.

Abstract: A base station or other network component (next generation NodeB (gNB)) can operate to transmit a channel state information reference signal (CSI-RS) for channel state information (CSI) feedback.

Abstract: A next generation evolved Node B (gNB) configured to provide an unlicensed bandwidth for communications with a user equipment (UE) performs a listen-before-talk procedure to determine an occupation state of busy or idle for the unlicensed bandwidth. When the occupation state is determined by the gNB to be idle, the gNB signals the UE, via a downlink control indicator (DCI), to conduct a channel access measurement (CAM) on the unlicensed bandwidth, the measurement comprising at least one of an energy detection measurement or a signal quality measurement. A measurement report is received from the UE comprising an indication of the occupation state of the unlicensed bandwidth as determined by the UE.

Abstract: Methods and apparatus provide for a wireless network to enable multiple-transmission reception point (multi-TRP) uplink (UL) time division multiplexed (TDMed) repetition transmission. The network may receive, from a user equipment (UE), beam measurements of downlink reference signals associated with a plurality of UL transmission beams from the UE to the multi-TRP. Based on criteria associated with the beam measurements received from the UE, the network enables the UE for the multi-TRP UL TDMed repetition transmission using the plurality of UL transmission beams. In addition, or in other scenarios, coordination is provided between the network and the UE to improve UL TDMed repetition transmissions when a UE switches between antenna panels.

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 exemplary embodiments relate to user equipment (UE) monitoring one or more downlink reference signals for uplink power control. The UE may receive an indication that a downlink reference signal is assigned to the UE for a first operation. The first operation is uplink power control for an uplink signal. The UE then determines whether the UE is configured to monitor the downlink reference signal for a second different operation. When the UE is configured to monitor the downlink reference signal for the second different operation, the UE configures the downlink reference signal to be a pathloss reference signal that is to be used for the first operation.

Based on determining that the SSB is outside the DL BWP configured for the UE, at least one radio frequency (RF) communication parameter of the UE is adjusted to adjust an operating bandwidth of the UE, and the SSB is received using the adjusted operating bandwidth.
