Abstract: Methods, systems, and devices for wireless communications are described. SSB based inter-frequency measurements may include configuring a UE to perform inter-frequency measurements without measurement gap within a measurement window, and applying scheduling restrictions to prioritize the inter-frequency measurements over uplink transmissions within the measurement window. The measurement window includes an SMTC window duration. Measurement resource sharing or restriction is described for SSB based inter-frequency measurement objects without measurement gap.

Abstract: Embodiments are presented herein of apparatuses, systems, and methods for a user equipment device (UE) and/or cellular network to perform to perform cell detection and measurement, e.g., in new radio (NR) unlicensed (NR-U). The UE may determine that a threshold condition related to missed reference signal opportunities is reached. In response, the UE may modify reference signal monitoring and/or measurement.

Abstract: Techniques discussed herein can facilitate configuration of a User Equipment (UE) with two or more Discontinuous Reception (DRX) configurations. A first set of techniques can facilitate configuration of the UE with independent DRX configurations for Frequency Range 1 (FR1) and for Frequency Range 2 (FR2). A second set of techniques can facilitate configuration of the UE with independent DRX configurations for a first set of one or more Component Carriers (CCs) associated with a first frequency band of a supported band combination and for a second set of one or more CCs associated with a second frequency band of the supported band combination. Various embodiments can employ techniques of one or more of the first set of techniques or the second set of techniques.

Abstract: Methods and apparatus are provided for a UE to determine a UL spatial relation for an UL transmission in response to an unknown UL spatial relation switch. The UE may determine whether the UL spatial relation is based on an SRS transmission in UL, a CSI-RS in DL, or an SSB in the DL. If the UL spatial relation is based on the SRS transmission, the UE may select the UL spatial relation for the UL transmission corresponding to a Tx beam of the SRS transmission. If the UL spatial relation is based on the CSI-RS or the SSB, the UE may select the UL spatial relation for the UL transmission based on whether the unknown UL spatial relation switch s due to a corresponding resource for beam training not being configured by a communication network or a corresponding beam information being expired.

Abstract: Apparatuses, systems, and methods for enhancement of MBMS transmission reliability. A UE may receive PDCP PDUs via a PTM link from a network. The UE may determine to provide feedback regarding receipt of the PDCP PDUs, e.g., based, at least in part, on an occurrence of a triggering event. The triggering event may be configured by the network and may include the UE receiving a request for feedback from the network, the UE determining that at least one PDCP PDU is missing, the UE determining that a number of missing PDCP PDUs exceeds a threshold, and/or the UE determining that a PDCP reordering window is changing based on expiration of a PDCP reordering timer. The UE may transmit feedback associated with receipt of the PDCP PDUs. The feedback may include an indication of missing PDCP PDUs, e.g., such as an indication of a sequence number associated with missing PDCP PDUs.

Abstract: Sidelink pathloss between a remote user equipment device (UE) and a relay UE may be determined based at least on transmit power information provided by the relay UE to the remote UE. The remote UE may receive, via a sidelink discovery signal from the relay UE, a message that includes first information representative of a transmit power of the relay UE and/or second information representative of a measured receive signal power of a sidelink solicitation signal previously transmitted by the remote UE and received by the relay UE. The remote UE may determine a sidelink pathloss between the remote UE and the relay UE based at least on the first information and/or the second information. The remote UE may select/reselect a relay UE based on corresponding pathlosses determined for the respective paths between the remote UE and different respective relay UEs.

Abstract: Determining priority of a simultaneous sidelink (SL) transmission and uplink (UL) transmission of a user equipment (UE) within a 5G New Radio (NR) network may comprise processing an SL control information (SCI) corresponding to at least one of a SL hybrid automatic repeat request (HARQ) or an SL schedule request (SR) included in a UL transmission to be sent by a UE to thereby determine a priority value associated with the at least one SL HARQ or SL SR. An SCI of an SL transmission to be sent by the UE simultaneously with the UL transmission may be processed to thereby determine a priority value associated with the SL transmission. The priority value of the at least one SL HARQ or SL SR may be compared to the priority value of the SL transmission. Transmissions may then be prioritized based on the comparison of priority values.
