Abstract: Systems, apparatuses, methods, and computer-readable media are provided for user equipment (UE) idle mode operations. In embodiments, a UE wakes up more than once during a Discontinuous Reception (DRX) cycle. Inter-frequency measurement requirements may be relaxed based on DRX cycle length. Some embodiments include radiofrequency (RF) circuitry warm-up overhead reduction by on-duration separation with RF circuitry switching pattern adaption. Some embodiments include and RF circuitry warm-up overhead reduction by adaptive synchronization signal block (SSB) reference symbol down-selection. Other embodiments may be described and/or claimed.

Abstract: Techniques described herein involve the use of quasi-co-location (QCL) capabilities and spatial relation assumption to enable a UE to designate a single beam for connections with a base station during a physical random access channel (PRACH) procedure. Once the PRACH procedure is complete, the beam may be reset after a pre-determined duration, which may account for decoding latency, or maintained until additional transmission configuration indication (TCI) is received. Also addressed are scenarios involving multiple transmission reception points (TRPs) and switching between beam management schemes based on one or more factors including device capabilities.

Abstract: This disclosure provides details of sequence-based WUS design and signaling, also DCI-based WUS design which also serves as scheduling DCI. For sequence-based WUS there are two variants. A first is based on CSI-RS, that is relatively wide band so the sequence occupies wider band compared to SSB transmission. The second is more akin to the Secondary Synchronization Signal (SSS) type of sequence in that it occupies a narrower band over the entire bandwidth.

Abstract: The present application relates to selecting one or more of activated transmission configuration indicator (TCI) states for communications between a network and a user equipment. In an example, the network includes multiple transmission and reception points (TRPs) with which the UE communications. An activated TCI state can be a unified downlink TCI state that applies to multiple downlink channels or a unified uplink TCI state that applies to multiple uplink channels, where this state has already been activated by the network for the UE. Based on a predefined set of rules or network-based signaling, the UE can determine for a downlink or uplink communication with the network, one or more of the activated TCI states to use to then perform the downlink or uplink communication with the network.

Abstract: Disclosed are methods, systems, apparatus, and computer programs for a coordination mechanism between a network and a user equipment (UE) that is configured to perform cross-link interference (CLI) measurements. In one aspect, a method includes generating a message that indicates a capability of a user equipment (UE) whether to support simultaneous reception of at least one signal associated with cross-link interference (CLI) measurement and at least one signal associated with a serving cell or a neighbor cell of the UE. The method further includes transmitting the message to an access node (AN).

Abstract: A user equipment (UE) is configured to establish a network connection including a new radio (NR)-NR dual connectivity band combination wherein a primary cell (PCell) of a primary cell group (PCG) and a primary secondary cell (PSCell) of a secondary cell group (SCG) both operate on frequency range 1 (FR1) and wherein at least one cell of either the PCG or the SCG operates on frequency range 2 (FR2). The UE receives a measurement gap timing advance parameter, selects one subframe from multiple serving cell subframes and determines a starting point for a configured per-frequency range (FR) measurement gap based on the measurement gap timing advance parameter and the selected subframe.

Abstract: Apparatuses, systems, and methods for multi-TRP by a UE, including out of order delivery of PDSCH, PUSCH, and/or DL ACK/NACK. The UE may receive, from a base station, a configuration that may include multiple control resource set (CORESET) pools and each CORESET pool may be associated with an index value. The UE may determine that at least two DCIs of the multiple DCIs end at a common symbol and determine, based on one or more predetermined rules, when the UE may be scheduled to receive PDSCHs, transmit PUSCHs, and/or transmit ACK/NACKs from CORESETs associated with the at least two DCIs.

Abstract: The present application relates to devices and components including apparatus, systems, and methods to provide DRX groups for licensed and unlicensed bands. For example, a first DRX group can be used in association with an NR licensed band of FR1, a second DRX group can be used in association with NR-U of FR1, and a third DRX group can be used in association with FR2. In this way, power savings of DRX groups can be granular to the level of licensed and unlicensed bands.
