A method and apparatus for transmitting location information of a serving small cell in a wireless communication system is provided. A first evolved NodeB (eNB), which may be a master eNB (MeNB) in dual connectivity, receives the location information of the serving small cell served by a second eNB, which may be a secondary eNB (SeNB) in dual connectivity, from the second eNB, and transmits the received location information of the serving small cell to a mobility management entity (MME).

The present disclosure relates to a pre-5th-generation (5G) or 5G communication system to be provided for supporting higher data rates beyond 4th-generation (4G) communication system such as a long term evolution (LTE). A method by a first base station (BS) in a cooperative communication system includes performing a medium access control service data unit (MAC SDU) synchronization process with a data gate way (GW) and at least one second BS; determining a first internet protocol (IP) packet received by the at least one second BS; and performing an IP packet transfer operation with the data GW and the at least one second BS based on whether at least one IP packet, of which a sequence number (SN) is less than a SN of the first IP packet, is buffered.

At least one embodiment takes the form of a process carried out by a given mobile radio in a group of mobile radios. The process includes broadcasting heartbeat messages in accordance with a group-wide symmetric-timing protocol and maintaining an in-range list of mobile radios. The in-range list is maintained at least in part by (i) adding mobile radios that are not already on the in-range list to the in-range list upon detecting transmissions from such mobile radios; (ii) maintaining, for each mobile radio on the in-range list, a respective keepalive timer in accordance with the group-wide symmetric-timing protocol; and (iii) removing mobile radios from the in-range list upon expiration of the respective keepalive timers. The process further includes presenting an alert via a user interface when a count of mobile radios on the in-range list falls below a notification threshold.

Method, base unit and control node for misused aerial usage identification are disclosed. A method comprises: receiving location information of a mobile unit; judging whether the mobile unit is a registered aerial vehicle or an unregistered aerial vehicle; determining whether the mobile unit is in the state of flying based on the location information of the mobile unit; and identifying the mobile unit as a misused aerial vehicle in the condition that the mobile unit is determined as in the state of flying and is judged as the unregistered aerial vehicle.

Apparatuses, systems, and methods relate to technology to identify first performance metrics associated with a first plurality of remote devices, determine first reliability weightings based on the first performance metrics, and identify one or more characteristics of an emergency based on the first reliability weightings and data from a first plurality of communications, where the first plurality of communications are associated with the first plurality of remote devices.
