Abstract: A wireless device (14) transmits, to a radio network node (12), a radio resource control (RRC) connection request (18) that requests the establishment, re-establishment, or resumption of an RRC connection (16). The RRC connection request (18) indicates a type of core network to which the wireless device (14) selects to connect. The wireless device (14) in some embodiments receives a response to the RRC connection request (18), based on the type of core network to which the wireless device (14) selects to connect. For example, the wireless device (14) may receive the response using a protocol stack determined based on the type of core network to which the wireless device (14) selects to connect.

Abstract: Data that is predicted across pictures in a video sequence is managed by separating the data into multiple data types. Instead of keeping all data associated with a decoded picture, such as picture sample values and motion vector data, data associated with a decoded picture is split by data type to enable storing only a subset of all data associated with a decoded picture.

Abstract: A method performed by a first network node (111) operating in a wireless communications network (100) with a Radio Access Technology with a split architecture. The first network node (111) is a Centralized Unit and a second network node (112) is a Distributed Unit. The first network node (111) detects (801) a RACH configuration between a served cell and a neighbor cell, and sends (802) a first indication to the second network node (112) based on the conflict. The first indication comprises at least one of: i) a notification of the conflict, ii) assistance information associated to the conflict, iii) a request for assistance information, and iv) a request to resolve the conflict. The first network node (111) then receives (803) one or more second indications from the second network node (112), wherein at least one is based on a result of a verification of an existence of the conflict.

Abstract: Sidelink (SL) Radio Link Failure (RLF) handling in Multi-Radio Dual Connectivity (MR-DC) scenarios is provided. Systems and methods are disclosed herein for handling SL RLF detection and declaration for an SL unicast link in MR-DC scenarios. In some embodiments, when an RLF is detected on one of a pair of SL User Equipments (UEs), a message is sent to a primary or secondary node to notify a serving network about the failure. In this case, either the primary node or secondary node may try to reconfigure the SL UEs, thus guaranteeing SL service continuity. Further, in some embodiments, once the network is informed that the SL radio channel has failed, the SL service continuity may be guaranteed by a Master Node (MN)-Secondary Node (SN) coordination regarding the SL configuration and connectivity handling (e.g., resource coordination, mode transmission, and so on).
