Abstract: Methods and apparatuses are described herein for 5G MBS operation. The proposed method and procedures overcome the limitations that have been observed in LTE and UTRAN MBMS operation, address the unique characteristic of 5G NR, and meet the requirements set out by the envisioned 5G MBS use cases by providing functions including RAN xcasting area concepts that are flexible and dynamic, MBS radio bearer (MRB) types to support MBS services, RAN architectures to support the various MBS radio bearer types, as well as functionality split across the RAN nodes to support these radio bearers, procedures to allow radio bearer selection, monitoring, and switching, and procedures to allow xcast area management.

Abstract: Methods, systems, and apparatuses may assist scheduling for broadcast and groupcast on new radio Uu interface. In an example, there may be broadcast and groupcast transmission scheduling mechanism with: group based scheduling, UE specific based scheduling, or sub-group based scheduling. In another example, there may be a serving cell configuration for broadcast and groupcast transmission with dedicated cell for broadcast and groupcast, or broadcast and groupcast cell which is shared with the cell for unicast. In another example, there may be downlink control related configuration for broadcast and groupcast transmission with details of the BWP configuration, the CORESET configuration, or the search space configuration.

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.

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.

Abstract: Wireless User Equipment, UE, and network apparatuses may be adapted to facilitate continuity of Multicast/Broadcast Service, MBS, across cells. A UE in idle/inactive mode, for example, may receive MBS assistance information comprising scheduling information defining MB S reception windows and perform a cell re selection evaluation process accordingly. An UE in connected mode may conduct and report MB S quality measurements and receive an RRC reconfiguration comprising an MB S configuration for a target cell, determine that MBS transmission progress differs between the source cell and the target cell, and recover lost MBS PDUs or delete duplicate MBS PDUs accordingly. A network apparatus, such as a gNB for example, may map a GPRS Tunneling Protocol Sequence Number of an MBS PDU, to a Packet Data Convergence Protocol Sequence Number in a target cell, and determine an MB S configuration for use by a UE requesting a handover accordingly.

Abstract: A wireless User Equipment (UE) may indicate to a base station (gNB) that the UE is capable of simultaneously using sidelink resource allocations Mode 1, with scheduling by the gNB, and sidelink resource allocation Mode 2 with scheduling by the UE, and then receive from the gNB, a Medium Access Control (MAC) entity configuration comprising information for Mode 1 and for Mode 2, and Sidelink Radio Bearer (SERB) configurations which may include the mode (Mode 1 or Mode 2) for the SERB. The UE may determine grants for both modes. In case of a grant collision or overlap, the UE may use logical channel priority to select one grant over the other. The UE may change from one mode to another. The MAC entity may take actions related to feedback, BSR reporting, and SR reporting, to manage the transitions.

Abstract: The exchange of resource allocation assistance information between a requester User Equipment (UE) and an assistant UE allows the requester to make better resource allocation decisions. The assistance information may include a blacklist, a whitelist, resource allocation information, a candidate resource set, and measurement information, for example. Both UEs may have an assistance configuration to assist in the exchange of resource allocation assistance information, that may be obtained from a third apparatus, such as a base station. The configuration may include information related to when to trigger assistance, identities of UEs, and types of assistance information, for example. The requester may, based on the assistance information received, modify a candidate resource set at a Medium Access Control (MAC) layer. The requester may, at the MAC layer, determine a configured sidelink grant for a selected destination using assistance information targeting this destination.

Abstract: Methods and apparatuses are described herein for transmission priority, collisions, and sharing in the COT by frame based equipment (FBE). In accordance with one embodiment, a wireless communications device such as an FBE, may conduct two stage channel sensing to avoid collision between other FBEs nodes. The wireless communications device may adjust the energy threshold to reflect a channel access priority. The FBE may conducting continuous and non-continuous second stage channel sensing. The FBE may perform enhanced two stage channel sensing to exploit the remaining portion of the COT. The FBE may store a configuration for the second stage of channel sensing for both the downlink (DL) and uplink (UL).

Abstract: The present application at least describes a method for obtaining channel access in a network. The method includes a step of selecting, via a gNodeB, a spatial filter from a first set of spatial filters to perform listen before talk (LBT). The method includes a step of detecting, via the gNodeB, a channel in an idle state. The method also includes a step of obtaining, a directional channel occupancy time (COT) in the channel in a direction of the selected spatial filter. The method also includes a step of transmitting, to a node, a channel access indicator transmission (CAI-T) on a beam in the cot via a spatial filter of a second set of spatial filters. The method further includes a step of receiving, from the node, a channel access indicator response (CAI-R). The method further includes a step of sensing, via short channel sensing and via the spatial filter or another spatial filter of the second set of spatial filters, the channel is clear. The method even further includes a step of sending, via the channel, information to the node using one or more spatial filters of the second set of spatial filters. Other embodiments of this aspect include corresponding computer systems, apparatus, and computer programs recorded on one or more computer storage devices, each configured to perform the actions of the methods.
