Abstract: Methods and apparatuses are described herein for remote UE mobility management. Methods are proposed to consider the impact of coverage through PC5 interface when a remote UE is doing the cell (re)selection. A remote UE may select a serving cell considering the impact of coverage through PC5 interface when the remote UE and the Relay UE are in coverage of different cells. The remote UE may detect and reselect a cell via the Uu interface while it has selected a serving cell via a Relay UE. The remote UE may detect and reselect to a cell via a Relay UE while it has selected a serving cell via the Uu interface.

Abstract: Network Slice Selection Assistance information (NSSA1) may be signaled between U ser Equipment (UE) and a network. NSSA1 sent from the network to the UE may include, for example. Operating Frequency Band (OFB) for each Single NSSAI(S-NSSA1) in the NSSAI, as well as a Radio Access Technology (RAT) Frequency Selection Priority (RFSP) index, which the network configures as a part of UE access and mobility; subscription, during a UE registration procedure. RAT restrictions may be enhanced to indicate to the UE that certain slices are not accessible via certain RATs. A UE may be provided by the network with an alternative NSSAI and corresponding OFBs for each S-NSSAI thereby indicating to the UE that these S-NSSAI would have been allowed had they been requested. A UE may be able to choose an alternative Allowed NSSAI and send a registration update request to the network.

Abstract: Blind coverage for wireless devices is enhanced varying one or more transmission characteristics of a repeated transmission sent or received by apparatuses, where the repeated transmission includes, for example a Physical Downlink Shared CHannel (PDSCH) and/or a Physical Uplink Shared CHannel (PUSCH) transmissions. Varied characteristics may include a start time for each repetition, a duration for each repetition, a start frequency for each repetition, a bandwidth of each repetition, a number of repetitions for each subframe, and/or a number of repetitions for each slot. Repetitions may be within a Bandwidth Part (BWP) or span multiple BWPs. Repetitions may vary from one to another in start time, start frequency, duration, bandwidth, and slot and subframe patterns. Higher level signalling, such as Radio Resource Control (RRC) signalling may be used to control the inclusion or omission of a DeModulation Reference Signal (DMRS) in repeated transmissions.

Abstract: SL DRX mechanism is used for power savings, to address a number of sidelink non-vehicular sidelink use cases. Methods, systems, and apparatuses, among other things, as described herein may use 1) A sidelink state model to describe the UE behavior for sidelink DRX operation. The DRX operation tailored to each of the sidelink states; 2) Power savings opportunities during SL operation, in addition to stopping PSCCH monitoring; 3) Various DRX models applicable to the sidelink; 4) SL_DRX operation for the SL UnLinked state; or 5) SL DRX operation for the SL_Linked state.

Abstract: Multicast/Broadcast Service (MBS) for user equipments (UE) in Radio Resource Control (RRC) idle/inactive modes via signally of MBS frequency ranges and/or switching between frequency ranges as required. Bandwidth Part (BWP) operation for MBS in RRC IDLE and RRC INACTIVE states may be implemented using a dedicated MBS BWP or by sharing a frequency range with other operations. An MBS frequency range may be wider or narrower than an initial BWP used by a UE, for example. MBS frequency range configure may be achieved in a number of ways, such as via Control Resource Set (CORESET), search space, and/or PDCCH monitoring occasions pattern settings for MBS in RRC idle/inactive. Downlink scheduling without dynamic grant for MBS in RRC idle/inactive may include configured scheduling and/or semi-persistent scheduling. Downlink repetition for MBS in RRC idle/inactive may include PDSCH repetition and/or PDCCH repetition

Abstract: A radio apparatus communicating with a first and a second network, and having a first connection to the first network, may receive a page from the second network and determine to form a second connection with the second network, and notify the first network of the selection. The first network may then notify the apparatus to release or suspend the first connection. The apparatus may send release and/or suspension preferences to the first network, such as a preference to be treated in an idle or inactive mode, paging preferences, and a preferred identifier of the apparatus. The apparatus may then form the second connection, and monitor for paging from the first network, e.g., during a given paging occasion and paging frame.

Abstract: The present application describes methods and systems for cell selection and reselection. One aspect describes the apparatus including a non-transitory memory including executable instructions for cell selection or cell reselection, which when executed by a processor, performs the instructions of determining one or more new public land mobile networks (PLMNs) have been selected. The processor is also configured to execute the instructions of scanning radio frequencies for one or more cells in one or more of the selected PLMNs. The processor is further configured to execute the instructions of determining the one or more cells to be an acceptable cell, a suitable cell, not an acceptable cell, or not a suitable cell. The processor is even further configured to execute the instructions of determining a state of the apparatus to be a multi-camped normally state, a reduced power any cell selection state, a reduced power camped on any cell, a camped normally state, an any cell selection state, or a camped on any cell state.
