Abstract
A base station and method are provided for transmitting data of a multimedia broadcast multicast service (MBMS) by the base station in a wireless communication system. The method includes receiving one or more service data units (SDUs) from a core network node; receiving a control message including respective length information of the SDUs transmitted from the core network node; identifying one or more subframes impacted by a loss of two or more consecutive SDUs based on the length information if the two or more consecutive SDUs are not received; and muting the identified one or more subframes impacted by the loss of the two or more consecutive SDUs.
Claims8
A method by a base station in a wireless communication system, the method comprising:
- receiving a plurality of service data units (SDUs) from a core network node;
- receiving a control message including a plurality of length information respectively corresponding to the plurality of SDUs from the core network node;
- identifying one or more subframes impacted by a loss of at least two consecutive SDUs based on the control message, if the at least two consecutive SDUs are not received;
- and
- muting the identified one or more subframes impacted by the loss of the at least two consecutive SDUs,
- wherein the plurality of SDUs and the control message are received separately.
A base station in a wireless communication system, the base station comprising:
- a transceiver for transmitting and receiving a signal;
- and
- a controller for:
- receiving a plurality of service data units (SDUs) from a core network node,
- receiving a control message including a plurality of length information respectively corresponding to the plurality of SDUs from the core network node,
- identifying one or more subframes impacted by a loss of at least two consecutive SDUs, based on the control message, if the at least two consecutive SDUs are not received, and
- muting the identified one or more subframes impacted by the loss of the at least two consecutive SDUs,
- wherein the plurality of SDUs and the control message are received separately.
A method for transmitting data of a multimedia broadcast multicast service (MBMS) by a core network node in a wireless communication system, the method comprising:
- transmitting a plurality of service data units (SDUs) to be transmitted in an MBMS subframe to a base station;
- and
- transmitting a control message including a plurality of length information respectively corresponding to the plurality of SDUs to the base station,
- wherein the control message is used for identifying one or more subframes impacted by a loss of at least two consecutive SDUs, based on the control message, if the at least two consecutive SDUs are not received, and muting the identified one or more subframes impacted by the loss of the at least two consecutive SDUs, and
- wherein the plurality of SDUs and the control message are transmitted separately.
A core network node for transmitting data of a multimedia broadcast multicast service (MBMS) in a wireless communication system, the core network node comprising:
- a transceiver for transmitting and receiving a signal;
- and
- a controller for transmitting a plurality of service data units (SDUs) to be transmitted in an MBMS subframe to a base station, and transmitting a control message including a plurality of length information respectively corresponding to the plurality of SDUs to the base station,
- wherein the control message is used for identifying one or more subframes impacted by the loss of at least two consecutive SDUs, based on the control message, if the at least two consecutive SDUs are not received, and muting the identified one or more subframes impacted by the loss of the at least two consecutive SDUs, and
- wherein the plurality of SDUs and the control message are transmitted separately.
