The disclosure relates to a 5G or pre-5G communication system for supporting a higher data rate after a 4G communication system such as LTE. A method according to an embodiment of the disclosure is a control method in an edge enabler server (EES) of a mobile edge computing system, and may include subscribing to a user plane path change event at an edge application server (EAS); determining an application context relocation (ACR) based on receiving a user plane path management event notification from the mobile communication network in case of subscribing to the user plane path change event for the EAS; transmitting an ACR request message to the EAS; receiving an EAS response message from the EAS; and transmitting an application function (AF) acknowledgment message to a first node of the mobile communication network in response to receiving the EAS response message from the EAS.

In a communication system having a plurality of user equipment (UE) devices that are operating in a contention based mode for device-to-device (D2D) communication, each UE device transmits a preferred transmission indicator when a condition for preferred transmission is met at the UE device. If a UE device receives a preferred transmission indicator, the UE device delays transmission of a D2D scheduling assignment (SA) to contend for communication resources for D2D communication. The length of the delay can be based on a number of preferred transmission indicators that are received. The preferred transmission indicator is based on a buffer size in one example.

A radio station (2) transmits configuration information (501) to a radio terminal (1). The configuration information (501) indicates, on a cell-by-cell basis, at least one specific cell on which the radio terminal (1) is allowed to perform at least one of data transmission and data reception on a radio bearer used for uplink transmission or downlink transmission or both via a common Packet Data Convergence Protocol (PDCP) layer (402). As a result, in a radio architecture that provides tight interworking of two different Radio Access Technologies (RATs), it is for example possible to allow an eNB to indicate, to a radio terminal (UE), a specific cell on which the UE should perform uplink transmission.

A radio access network handover method of a base station in a 5G radio access network (5G-RAN) is are disclosed. The method comprising: determining handing over a user equipment (UE) to an Evolved Universal Terrestrial Radio Access Network (E-UTRAN); transmitting a handover requirement message to an Access and Mobility Management Function (AMF); receiving a handover command message from the AMF and transmitting the handover command message to the UE, the handover message such that the UE is handed over from the 5G-RAN to the E-UTRAN; and performing indirect data forwarding to a base station in the E-UTRAN.

Apparatuses, methods, and systems are disclosed for managing a C2 communication mode of operation. One apparatus includes a transceiver supporting a network interface that receives an application request to manage an operation mode of C2 communication for a first UAS. Here, the first UAS comprises a first UAV and a first UAV-C. The network interface receives a first report from an application of the first UAS, where the first application is located in one of the first UAV and the first UAV-C. The apparatus includes a processor that determines to switch the operation mode of C2 communication for the first UAS based on the received first report and transmits, via the network interface, a C2 communication switching instruction to the first UAS.

According to one example embodiment, a method may include receiving, by a user equipment, at least one buffer status report configuration from a network entity. The method may further include measuring, by the user equipment, at least one uplink packet arrival time according to the received at least one buffer status report configuration. The method may further include selecting, by the user equipment, at least one buffer status report format. The method may further include transmitting, by the user equipment, at least one uplink time-stamped buffer status report to the network entity according to the selected at least one buffer status report format.
