Abstract: A method and apparatus for transmitting a cell shaping/un-shaping indication in a wireless communication system is provided. A first eNodeB (eNB) transmits a cell shaping/un-shaping indication which indicates cell shaping/un-shaping of a cell, managed by the first eNB, in an active antenna system (AAS) to a second eNB. The cell shaping means that main coverage of the cell is maintained unchanged but an edge of the cell can be adapted to load demand. The cell un-shaping means that coverage of the cell goes back to original coverage.

Abstract: A method and apparatus for transmitting an indication in a wireless communication system is provided. An eNodeB (eNB) of a first system transmits an indication, which indicates that handover of a user equipment (UE) from the eNB to a radio network controller (RNC) of a second system is a necessary handover, to the RNC. In addition, a method and apparatus for receiving an indication for inter-radio access technology (RAT) unnecessary handover in a wireless communication system is provided. An eNB of a first system transmits a request for measuring, by a UE, quality of signals from the first system, and information related to the inter-RAT unnecessary handover, and receives an indication for the inter-RAT unnecessary handover.

Abstract: A method and apparatus for fast small data transmission in a wireless communication system is provided. A last serving RAN node receives, from the wireless device and via a new RAN node, an AS-RAI related to early data transmission. A last serving RAN node decides whether a UE context relocation to the new RAN node for the wireless device is required or not based on the received AS-RAI. A last serving RAN node transmits, to the new RAN node, an RRC message based on the decision.

Abstract: A method and apparatus for small data transmission without a path switch procedure in a wireless communication system is provided. A new gNB, which is a radio access network (RAN) node to which a wireless device attempts a connection resume procedure while in an inactive state, receives an anchor kept indication and/or a small data indication from a last serving gNB. The anchor kept indication indicates that the last serving gNB keeps a user equipment (UE) context and/or a UE-associated NG connection with the core network. The small data indication indicates not relocating a UE context from the last serving gNB to the new gNB.
