Abstract
Even when a radio terminal cannot receive content data from a base station to which the radio terminal serves, the radio terminal receives the content data from other base station. A wireless communication system (1) includes a plurality of radio base stations (21 to 23) and a radio terminal (40). The radio terminal (40) serves to a specific radio base station (serving radio base station) among the radio base stations (21 to 23). Moreover, the radio terminal (40) receives content data which is broadcasted or multicasted from a non-serving radio base station among the radio base stations (21 to 23) according to a gap pattern.
Claims24
A wireless communication system comprising:
- a radio terminal;
- a serving radio base station that is serving the radio terminal;
- and
- a non-serving radio base station that is not serving the radio terminal, wherein
- the radio terminal receives a Multimedia Broadcast and Multicast Service (MBMS) control information, which is related to a MBMS content data, sent via at least one of Broadcast Control Channel (BCCH) and Multicast Control Channel (MCCH) in a non-serving cell served by at least one of the serving radio base station and the non-serving radio base station, and
- the radio terminal transmits information that indicates radio resource information of the MBMS content data to the serving base station.
A radio terminal comprising:
- a receiver that receives Multimedia Broadcast and Multicast Service (MBMS) control information, which is related to a MBMS content data, sent via at least one of Broadcast Control Channel (BCCH) and Multicast Control Channel (MCCH) in a non-serving cell served by at least one of a serving radio base station that is serving the radio terminal and a non-serving radio base station that is not serving the radio terminal, and
- a transmitter that transmits information that indicates radio resource information of the MBMS content data to the serving base station.
A radio base station comprising:
- a transmitter that transmits Multimedia Broadcast and Multicast Service (MBMS) formation, which is related to a MBMS content data, sent via at least one of Broadcast Control Channel (BCCH) and Multicast Control Channel (MCCH), and
- a receiver that receives information that indicates radio resource information of the MBMS content data from a radio terminal,
- wherein the information is received by the radio terminal in a non-serving cell served by at least one of the radio base station that is serving the radio terminal and other radio base station that is not serving the radio terminal.
A communication method performed in a wireless communication system that includes a radio terminal, a serving radio base station that is serving the radio terminal, and a non-serving radio base station that is not serving the radio terminal, the communication method comprising:
- receiving, by the radio terminal, a-Multimedia Broadcast and Multicast Service (MBMS) control information, which is related to a MBMS content data, sent via at least one of Broadcast Control Channel (BCCH) and Multicast Control Channel (MCCH) in a non-serving cell served by at least one of the serving radio base station and the non-serving radio base station, and
- transmitting, by the radio terminal, information that indicates radio resource information of the MBMS content data to the serving base station.
A communication method performed in a radio terminal comprising:
- receiving Multimedia Broadcast and Multicast Service (MBMS) control information, which is related to a MBMS content data, sent via at least one of Broadcast Control Channel (BCCH) and Multicast Control Channel (MCCH) in a non-serving cell served by at least one of a serving radio base station that is serving the radio terminal or a non-serving radio base station that is not serving the radio terminal;
- and
- transmitting information that indicates radio resource information of the MBMS content data to the serving base station.
A communication method in a radio base station comprising:
- transmitting Multimedia Broadcast and Multicast Service (MBMS) control information, which is related to a MBMS content data, sent via at least one of Broadcast Control Channel (BCCH) and Multicast Control Channel (MCCH);
- and
- receiving information that indicates radio resource information of the MBMS content data from a radio terminal, wherein
- the information is received by the radio terminal in a non-serving cell served by at least one of the radio base station that is serving the radio terminal and other radio base station that is not serving the radio terminal.
