Abstract: Techniques are disclosed for the spectrum sharing without network sharing. One example includes a method implemented for spectrum sharing without network sharing. A first network node can transmit, via a horizontal user plane interface, a first message to a second network node. The message can include a request for shared spectrum. The first network node can be configured to transmit a first network identifier associated with a first operator. The second network node can be configured to transmit a second network identifier associated with a second operator. The first network node can receive, via the horizontal user plane interface, a second message from the second network node. The second message can coordinate shared spectrum access between the first network node and the second network node. The first network node can access the shared spectrum, based on the response.

Abstract: The present application relates to user equipment (UE) aggregation. For instance, a UE aggregation group is defined based on a subscription of multiple UEs with a network. Configuration information identifying the UE aggregation group, its member UEs, the role of each UE (e.g., whether a group leader or, otherwise, a group member), and/or radio access capability signaling (RACS) is stored. Upon a registration of a UE, the UE aggregation group is indicated to the network. The network then enables an aggregated communication capability to the UEs of the UE aggregation group based on the configuration information.

Abstract: Methods, systems, apparatuses, and computer programs for enhancing UE handover. In one aspect, the method can include obtaining a request for a handover event from a UE, wherein the request includes at least (i) a request for access to a primary cell group and (ii) data indicating capabilities of the UE, determining, based on the UE capabilities, that the UE is capable of maintaining communication with a secondary cell group of a base station during handover of the UE to the primary cell group of the first base station, generating based on the determined UE capability, a handover command that instructs the UE to maintain communication with the secondary cell group of the base station during handover of the UE to the primary cell group, encoding the generated handover command for transmission to the UE, and transmitting the generated handover command to the UE.

Abstract: A UE may perform a location-based conditional handover (CHO) based on a region information and size parameter associated with a serving cell of a non-terrestrial network (NTN). In time-based CHO, the UE may perform CHO in response to expiration of a network-configured wait time. Alternatively, the UE may perform CHO by randomly selecting a wait time from a network configured time range. The selection may be randomized using a network provided seed or using a cell Radio Network Temporary Identifier (RNTI) value. In elevation-based CHO, the UE may perform CHO in response to the elevation angle of a satellite being less than a network configured threshold. When the UE is configured with multiple cells of the NTN, and the CHO criteria for two or more of the cells are satisfied, the UE may select a target cell for CHO based on network indicated prioritization of the cells.
