Abstract:
A method and an apparatus for providing user equipment at a boundary with reference information for starting the scanning of a heterogeneous access network are provided. For this purpose, a receiver, according to one embodiment, supports a plurality of access systems, and comprises: a receiving circuit for receiving a scanning threshold value from a transmitter; a first measurement module which measures the channel quality of a serving cell; and a second measurement module which starts scanning a neighbor cell, which is a heterogeneous access network, when the channel quality of the serving cell is lower than the channel quality threshold value. In addition, the receiver can further comprise a handover module which performs a handover to the neighbor cell when the channel quality of the neighbor cell measured by the second measurement module is higher than the channel quality of the serving cell.
Abstract:
A terminal identifying method identifies a terminal in a media access control layer, and includes allocating a station ID to the terminal for identifying the terminal, and allocating a flow ID to a connection in the terminal for identifying the connection in the terminal.
Abstract:
A plurality of location-based service advertisement messages including location information of base stations belonging to each network are broadcasted with different timing in multiple wireless networks. Therefore, a terminal receives only at least on location-based service advertisement message corresponding to an accessible network among the plurality of location-based service advertisement messages.
Abstract:
In order to manage a neighbor list of neighboring base stations based on the location of a terminal communicating with a base station of a macrocell with femtocell deployments, the base station divides the macrocell in accordance with a predetermined standard of division, and generates a mobile neighbor advertisement message so as to periodically transmit the generated message to the terminal. At this time, the terminal identifies the current location thereof in the macrocell upon receipt of the pilot signals periodically transmitted from the base station of the macrocell. The terminal obtains information regarding the location of the terminal from the information regarding the femtocells deployed within the respective divided regions and information regarding macrocells neighboring the macrocell through using the mobile neighbor advertisement message to scan base stations.
Abstract:
A transmitting device for a multicast and broadcast service according to an embodiment of the present invention includes: an encoder that receives data to generate parity; an ARQ block generator that generates a first automatic repeat request (ARQ) block by dividing the data and generates a second ARQ block by dividing the parity; a PDU generator that generates a first protocol data unit (PDU) including the first ARQ block and a second protocol unit (PDU) including the second ARQ block; and a transmitter that transmits the first PDU and the second PDU to a plurality of terminals.
