Abstract: Apparatuses, systems, and methods for triggering and signaling of an inter-UE coordination message. A coordinating UE may determine to transmit, to a source UE, a set of resources for the source UE to use for sidelink communications. The determination may be based, at least in part, on an occurrence of at least one condition. The at least one condition may include the coordinating UE receiving a sidelink coordination request message form the source UE, the coordinating UE detecting a resource reservation collision between the source UE and a destination UE, and/or the coordinating UE detecting a half-duplex restriction at the source UE or the destination UE. The coordinating UE may transmit an inter-UE coordination message to the source UE. The inter-UE coordination message may include at least an indication of the set of resources.

Abstract: A user equipment (UE) configured to determine a resource selection window which identifies a first set (e.g., a total set) of candidate resources. The UE may then remove one or more candidate resources from the first set of candidate resources in response to receiving sidelink control information (SCI) from a pedestrian UE with a reservation of the one or more first candidate resources. After removal of these candidate resources from the initial or first set based on their presumed unavailability, the result may be a second set of candidate resources, which may be a subset of the initial or first set for use in communicating with a third UE. The UE may also be configured to remove candidate resources based on a reference signal receive power (RSRP) threshold which can also be adjusted based on a maximum value or a highest priority of the pedestrian UE's data.

Abstract: Provided is a method for constructing a hybrid automatic repeat request—acknowledge character (HARQ-ACK) codebook, performed at a user equipment (UE), comprising: generating HARQ-ACK information for at least one unicast downlink channel and HARQ-ACK information for at least one group-common downlink channel; and constructing the HARQ-ACK codebook based on the HARQ-ACK information for the at least one unicast downlink channel and the HARQ-ACK information for the at least one group-common downlink channel, wherein each group-common downlink channel associates with a MBS service.

Abstract: Disclosed are techniques for differentiating between licensed and unlicensed bands in a common portion of frequency spectrum to facilitate initial access in a fifth generation (5G) new radio (NR) wireless communication system having an NR node. The techniques include an NR generating and UE processing frequency configuration information indicating whether the common portion of frequency spectrum is allocated as a licensed band or an unlicensed band to enable a determination that the frequency spectrum is configured as the licensed band or unlicensed band and thereby facilitate initial access.

Abstract: Systems and methods disclosed herein describe the use of synchronization signal/physical broadcast channel block measurement time configuration (SMTC) 2 low power (SMTC2-LP) configuration(s). For cell measurements, a UE may determine that an SMTC2-LP configuration for one or more carriers of one or more target cells is known, determine a periodicity of SMTC occasions of the carrier(s) based on data found in the SMTC2-LP configuration(s), and cancel a cell measurement of an inter-frequency cell based at least in part on the periodicity of the SMTC occasion(s). For cell re-selection, a UE may determine that an SMTC2-LP configuration for a carrier being used at a target cell is known and that a physical cell identity (PCI) of the target cell is found in data of the SMTC2-LP configuration, determine a maximum paging interruption time using this periodicity, and perform a cell reselection to the target cell within this time.

Abstract: Techniques for channel state information reference signal (CSI-RS) configuration in wireless communications are disclosed. A user equipment (UE) may decode a message including a CSI-RS configuration that indicates a CSI-RS window associated with one or more CSI-RS, with respect to one or more mobility related measurements. The UE may determine one or more mobility related measurements using the CSI-RS configuration, and measure the one or more CSI-RS using the determination of the one or more mobility related measurements. The UE may generate a report for the base station corresponding to the measurement of the one or more CSI-RS.

Abstract: This disclosure relates to techniques for signaling a quasi-colocation (QCL) update in a wireless communication system. A network or base station may indicate to a UE to change a spatial relationship for transmission/reception. The base station may provide aperiodic reference signals for the UE to use in beam tracking according to the new spatial relationship. Optionally, the base station may also provide aperiodic reference signals for time, frequency, and/or phase tracking. Thus, the network may configure the UE to change to the new spatial relationship and use the aperiodic reference signals to quickly complete initial tracking operations.
