Abstract: There is provided mechanisms for beam related statistics aided resumed beamformed communication with a terminal device. A method is performed by a radio access network node. The method comprises providing network access to the terminal device by, in a first set of beams, performing beamformed communication with the terminal device until the terminal device leaves radio resource control (RRC) connected mode. The method comprises storing beam related statistics of the beamformed communication. The method comprises providing resumed network access to the terminal device by, in a second set of beams, performing resumed beamformed communication with the terminal device upon the terminal entering RRC connected mode. How to perform the resumed beamformed communication is based on the beam related statistics.

Abstract: A second access and mobility management function (AMF) receives positioning capability information indicating that a location management component (LMC) supports one or more positioning types. The second AMF receives, from a first AMF, a message indicating a positioning type of a wireless device. The second AMF determines the LMC. The determining is based on the positioning type. The determining is based on the positioning capability information. The second AMF sends, to a base station associated with the determined LMC, an identifier of the determined LMC.

Abstract: Methods, systems, and devices for wireless communications are described a first donor node may serve a relay node, which in turn may serve a child node. The first donor node may determine to transfer (e.g., via a handover procedure) the relay node to a second donor node. The first donor node may transmit a first context transfer request for the relay node to the second donor node, and may transmit a second context transfer request for the child node of the relay node to the second donor node. The first donor node may indicate a correlation between the two context transfers. The second donor node may identify the correlated context transfers, and may successfully perform a migration procedure for the relay node and any descendent devices or nodes based on the correlated context transfers.

Abstract: Certain aspects of the present disclosure are directed to a method for wireless communication. The method generally includes receiving at least one first packet of a sequence of packets from a source cell, the at least one first packet being dependent on at least one second packet of the sequence of packets for decoding, performing a handover from the source cell to a target cell, determining that the at least one second packet of the sequence of packets was not received from the source cell, generating a message requesting a retransmission from the target cell for the at least one first packet and the at least one second packet based on the determination, and transmitting the message to the target cell.

Abstract: In one embodiment, a method includes receiving, by a mobile edge computing (MEC) controller and from an application analytic engine, a registration request for an application. The registration request includes a request for MEC key performance indicators (KPIs). The method also includes communicating, by the MEC controller, MEC data associated with a first MEC host and a second MEC host to the application analytic engine. The method further includes receiving, by the MEC controller, MEC policies from the application analytic engine, determining to host the application in the first MEC host based on the MEC policies, and communicating the MEC policies to the first MEC host.

Abstract: Embodiments of the present disclosure provide method and apparatus for handover management. A method performed by a first mobility management function in a first system comprises obtaining mobility management context for single radio voice call continuity (SRVCC). The method further comprises sending a forward relocation request to a second mobility management function in a second system during a handover from the first system to the second system. The forward relocation request comprises mobility management context for the SRVCC.
