摘要:
A method of supporting a security for a multicast communication is provided in a mobile station. The mobile station shares an MAK with a base station, derives a prekey based on a first parameter including the MAK, and derives a multicast security key including an MTEK based on a second parameter including the prekey, and decrypts a multicast traffic using the multicast security key.
摘要:
A group communication method of a terminal is provided. The terminal establishes a group call connection with a first base station belonging to a group call zone, and receives group call data from the first base station. When moving to the coverage area of a second base station belonging to the group call zone, the terminal receives group call data from the second base station.
摘要:
A method for performing direct communication, by a first terminal, between terminals, includes transmitting a control message for a direct communication resource allocation to at least one second terminal through a first region included in a direct communication resource, transmitting synchronization information to at least one second terminal through a second region included in the direct communication resource, and transmitting a data packet to at least one second terminal through a third region included in the direct communication resource.
摘要:
A method of controlling power saving modes of a plurality of terminals joining in a group communication by a base station is provided. The base station establishes a group call connection with the plurality of terminals, and establishes a same power saving mode pattern for the plurality of terminals.
摘要:
A multicast management method of a base station is provided. The base station generates a CRC for a message including resource allocation information of a multicast group including a plurality of terminals, and masks the CRC by a CRC mask. The base station adds the masked CRC to the message, and then transmits the message to which the masked CRC is added to the multicast group.
摘要:
Protocol structure of a mobile station, base station or relay station in a wireless access system is provided. The protocol structure includes a first function block configured to perform radio resource control and management as a MAC layer and to reside on a control plane, and a second function block configured to perform medium access control as the MAC layer and to reside on the control plane and a data plane. The first function block includes various function blocks for supporting high reliability.
摘要:
A method of configuring a cell of a terminal includes: transmitting, by the terminal, when the terminal searches for an idle band, a downlink frame; performing a network entry procedure with other terminals at 1 hop from the terminal; and optimizing, by the terminal, transmission power.
摘要:
A method for handover of the present invention is a method for handover of a terminal supporting a multi-carrier including a first carrier and a second carrier, the method including: transmitting a handover request message to a serving base station; receiving a handover response message from the serving base station according to a handover response message transmitted from a target base station to the serving base station; after receiving the handover response message from the serving base station, transmitting and receiving data to and from the serving base station using the first carrier; and performing a handover signaling process to the target base station using the second carrier.
摘要:
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.
