Abstract: Apparatuses, systems, and methods for selecting channel access mechanisms in wireless communications, and particularly in 3GPP NR-U. For example, an appropriate listen-before talk (LBT) channel access category (Cat) may be defined for certain messages, such as certain DL and/or UL control messages and certain RACH messages. For other messages, an appropriate Cat may be signaled by the base station, e.g., in a DCI message or SIB. Mechanisms are provided for the base station to signal to the UE certain channel access profile parameters, such as an appropriate LBT Cat, CAPC, and/or CP extension. Mechanisms are also provided for adjustment of contention window duration.

Abstract: Systems and methods for sidelink (SL) resource pool resource use by a user equipment (UE) are disclosed herein. In some embodiments, when the UE performs contiguous partial sensing in addition to periodic partial sensing, the UE performs one of resource selection and resource re-evaluation based a size of a time gap between a slot where the UE has SL data and a first slot of periodic-based candidate slots within a resource selection window. In other embodiments, the UE performs contiguous partial sensing without additional periodic partial sensing in the case where a packet delay budget (PDB) for the SL data is greater than a threshold. In some embodiments, the UE performs periodic partial sensing for resource re-evaluation and/or resource pre-emption according to a set of periodicity values Preserve,re-ev (and optionally period definition data Kre-ev). Restrictions on the use of random resource selection by the UE are also described.

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. The CSI feedback can be received as corresponding to one or more frequency parts at hierarchical precoding levels of a frequency band based on a hierarchical precoding scheme in response to providing the CSI-RS.

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 methods are provided for port selection codebook configuration. A user equipment (UE) may decode a channel state information (CSI) report configuration (CSI-ReportConfig) from a base station. The CSI-ReportConfig indicates up to L CSI reference signal (CSI-RS) ports for selection by the UE out of P CSI-RS ports configured for measuring and reporting CSI. The UE determines selected CSI-RS ports out of the P CSI-RS ports. The selected CSI-RS ports include the L CSI-RS ports or less. The UE generates a port selection matrix W1 corresponding to the selected CSI-RS ports. The UE also generates an indication of the port selection matrix W1 to the base station. The CSI-ReportConfig may further configure the UE to select a subset of frequency basis. The UE determines a selected subset of frequency basis and generates a frequency basis selection matrix Wf corresponding to the selected subset of frequency basis.

Abstract: A user equipment (UE), a base station (e.g., next generation NodeB (gNB)), or other network component can operate to configure a beam failure recovery (BFR) timing based on a time offset and a number of symbols in a BFR procedure, as well as enable beam switching and bandwidth part (BWP) switching to be correlated. A beam failure recovery request (BFRQ) can be processed or transmitted in response to a detection of a beam failure. A beam failure recovery response (BFRR) can be generated via a physical downlink control channel (PDCCH) based on at least four slots after the BFRQ and a time offset for a non-terrestrial network (NTN).

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 W1, a combinational coefficient matrix W2, and a frequency basis selection matrix Wf. 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 W1, the up to beta*L*Mv entries in the combinational coefficient matrix W2 per layer, and the frequency basis selection matrix Wf to the base station.

Abstract: A user equipment (UE) monitors a Physical Downlink Control Channel (PDCCH) in multiple component carriers (CC). The UE determines if the UE is operating in carrier aggregation (CA) mode having a first CC in a first frequency band and a second CC in a second frequency band. When the UE is operating in CA with a first CC in the first frequency band and the second CC in the second frequency band, the UE determines a span pattern for PDCCH symbols being received on the first and second CC and selects a PDCCH monitoring type based on, at least, the span pattern. A UE also determines if a first CC and a second CC of a CA combination are collocated and selects a PDCCH monitoring type based on, at least, the determination of whether the first and second CC are collocated.
