Abstract: A method and system for assigning a unique logical address in a cloud cell having a mobile station, slave base stations and a master base station are provided. The method includes determining at least one unassigned logical address from respective address spaces associated with the slave base stations and the master base station in the cloud cell by the master base station, selecting the unique logical address from the at least one unassigned logical address determined from the respective address spaces associated with the plurality of base stations, and assigning the selected unique logical address to the mobile station in the cloud cell. The mobile station and each of the plurality of base stations communicate in the cloud cell using the assigned unique logical address.

Abstract: A system and a method of counter management and security key update for device-to-device (D2D) communication are provided. The method includes creating by a user equipment, a new packet data convergence protocol (PDCP) entity for a service group wherein a service group is identified by a destination identifier (ID), determining if any PDCP entity of the service group exists or not, generating a new proximity service (ProSe) traffic key (PTK) from a ProSe group key (PGK) corresponding to the service group associated with the new PDCP entity, initializing a new packet counter associated with the service group to zero if the new PDCP entity is a first PDCP entity associated with the service group, generating a ProSe encryption key (PEK) from the PTK and encrypting data packets mapped to the new PDCP entity using the PEK and a packet counter associated with the service group.
