Abstract: Techniques discussed herein can facilitate the use of reference signals in active TCI switching. A user equipment (UE), comprising: a memory interface; and processing circuitry communicatively coupled to the memory interface and configured to: receive a physical downlink shared channel (PDSCH) message that includes an activation command indicating a target transmission configuration indicator (TCI) state; decode the activation command within a decoding period, where the decoding period is a time period allocated for the UE to decode the activation command; receive a TCI resource where the TCI resource is a reference signal; perform time and frequency tracking associated with the target TCI state according the TCI resource; and switch to the target TCI state after performing time and frequency tracking.

Abstract: A user equipment (UE), baseband processor or other network device (e.g., base station, next generation NodeB, etc. ) can operate to process or generate an acknowledgement (ACK) or a non-acknowledgement (NACK) of a beam report to indicate an autonomous transmission configuration indicator (TCI) state update, which can be a TCI update without a corresponding TCI indication /trigger. The UE can determine the ACK /NACK in response to providing the beam report in the autonomous TCI state update. The UE can then activate a TCI state of the autonomous TCI state update in response to identifying the ACK or re-transmit the beam report for autonomous TCI state update when a NACK is recognized.

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: Apparatus and methods are provided for port selection codebook configuration. A user equipment (UE) may receive, from a base station, an indication of parameter settings of a port selection codebook. The port selection codebook includes a port selection matrix W 1, a combinational coefficient matrix W 2, and a frequency basis selection matrix W f. Based at least in part on the parameter settings, the UE selects L CSI-RS ports, Mv frequency basis from a window of N consecutive frequency basis; and up to beta*L*Mv entries per layer, where beta is a percentage of the L*Mv entries per layer. The UE reports one or more of the port selection matrix W 1, the up to beta*L*Mv entries in the combinational coefficient matrix W 2 per layer, and the frequency basis selection matrix W f to the base station.

Abstract: Configuring channel state information reference signal (CSI-RS) reporting at a network may include encoding a channel state information (CSI) reporting configuration communication for transmission to a user equipment (UE) that is in connected mode with both a first transmission and reception point (TRP) and a second TRP. The CSI reporting configuration may include a first group of CMR (Channel Measurement Resource) resources for the first TRP, and a second group of CMR resources for the second TRP. A CSI measurement communication received from the UE, may be measurements based on the CSI-RS reporting configuration communication. Based on the CSI measurement communication, one or more downlink data transmissions may be scheduled.

Abstract: Systems and methods for beam failure recovery (BFR) are disclosed herein. A user equipment (UE) receives downlink (DL) reference signal (s) on corresponding beam (s) from a base station. The UE performs beam failure detection (BFD) on such beams used for user data to determine whether a beam failure has occurred, and candidate beam detection (CBD) on such beams not used for user data to identify candidate beams for recovering from the beam failure. The BFD and the CBD are based on both uplink (UL) channel performance considerations and DL channel performance considerations, as determined using the DL reference signal (s), such that a beam failure may be determined in the UL, the DL, or both, and a candidate beam may be identified for UL, DL, or both. The UE sends a beam failure recovery request BFRQ with this information to the base station, and the system changes beams accordingly.

Abstract: In sidelink carrier aggregation, a first user equipment (UE) transmits data packets to a second UE using a plurality of carriers. The second UE transmits Hybrid Automatic Repeat Request (HARQ) ACK/NACK information for the data packets to the first UE via one or more Physical Sidelink Feedback Channels (PSFCHs). The aggregated carriers may be constrained to have the same PSFCH configuration, or not. Resource selection for PSSCH transmission may be performed by considering scheduled PSFCH so as to conform to transmit capability limitations and/or a half-duplex limitation of the first UE and/or the second UE. The PSFCH may be transmitted on a single carrier of said plurality, but include joint HARQ feedback for each of the carriers. Furthermore, HARQ feedback may be transmitted on a Physical Sidelink Shared Channel (PSSCHs), being signaled by the receive UE (i.e., the UE that transmits the feedback) via sidelink control information (SCI).

Abstract: Aspects are described for a user equipment (UE) comprising a transceiver configured to enable wireless communication with a first transmission/reception point (TRP) and a second TRP and a processor communicatively coupled to the transceiver. The UE is in a multi-TRP mode. The processor is configured to perform a first beam failure detection (BFD) procedure for the first TRP and a second BFD procedure for the second TRP. The processor is further configured to perform a first beam failure recovery (BFR) procedure for the first TRP responsive to a result of the first BFD procedure and a second BFR for the second TRP responsive to a result of the second BFD procedure. The processor is further configured to receive a configuration message, a BFD configuration, and a BFR configuration. The UE switches to a single-TRP mode upon receiving the configuration message. The processor is further configured to update the first BFD procedure based on the BFD configuration and update the first BFR procedure based on the BFR configuration. Finally, the processor is configured to perform the updated first BFD procedure and the updated first BFR procedure for the first TRP responsive to a result of the updated first BFD procedure.

Abstract: A user equipment (UE) is configured to determine to perform a sounding reference signal (SRS) transmission with an antenna port switch operation, wherein the SRS transmission with the antenna port switch operation is performed during an SRS transmission occasion comprising one or more symbols of a slot and apply one or more scheduling restriction rules corresponding to the SRS transmission with the antenna port switch to provide one or more scheduling restrictions for the UE, wherein the scheduling restrictions cause the UE to omit performing at least one of transmission operations or reception operations during one or more symbols of the slot or one or more symbols of an adjacent slot.
