    摘要： A communications method and a mobile terminal that constructs a communications system which transmits data by using an OFDM (Orthogonal Frequency Division Multiplexing) method as a downlink access method, and also transmits data by using an SC-FDMA (Single Career Frequency Division Multiple Access) method as an uplink access method. The mobile terminal includes a processor that determines a candidate set including CCEs (Control Channel Elements), each of which is one of regions to which one frequency bandwidth is divided, for delivery of an L1/L2 control signal which is control information transmitted and received between a base station and the mobile terminal. In addition, the processor, which is at the mobile terminal, determines the candidate set based on the frequency bandwidth.

    摘要： Since OFDM (Orthogonal Frequency Division Multiplexing), which is a downlink access scheme used for an LTE (Long Term Evolution) communication system, is weak at interference, it is preferable that the number of base stations for transmitting the same E-MBMS (Evolved Multimedia Broadcast Multicast Service) data be not excessive.Thus, the mobile terminal performs: processing of obtaining measurement quality values by measuring reception quality of each base station; processing of deciding on whether the measurement quality value of a serving base station exceeds a certain receiving level; processing of adding measurement quality values of other base stations to the measurement quality value of the serving base station until the sum exceeds the certain receiving level; and processing of notifying the serving base station of the serving base station and other base stations as candidates for an active set for E-MBMS. This makes it possible to select as the active set for E-MBMS an appropriate number of base stations that make it compatible to maintain good reception quality and to prevent interference.

    摘要翻译： 由于作为用于LTE（长期演进）通信系统的下行链路接入方式的OFDM（Orthogonal Frequency Division Multiplexing，正交频分复用）在干扰方面较弱，因此优选用于发送相同E-MBMS（演进） 多媒体广播多播服务）数据不会过多。 因此，移动终端执行：通过测量每个基站的接收质量来获得测量质量值的处理; 决定服务基站的测量质量值是否超过某一接收电平的处理; 处理将其他基站的测量质量值添加到服务基站的测量质量值，直到该和超过某一接收电平; 以及将服务基站和其他基站的服务基站通知为用于E-MBMS的活动集的候选的处理。 这使得可以将适合数量的基站选择为E-MBMS的活动集，使其兼容以保持良好的接收质量并防止干扰。

    摘要： A mobile communication system capable of preventing interference in a communication system as well as reducing the load of a user equipment in a search operation. In the mobile communication system, radio communication is performed using a carrier having the same frequency in a direct link between a donor cell and a user equipment being served thereby and an access link between a relay node and a user equipment being served thereby. In a backhaul link between the donor cell and the relay node, radio communication is performed using a carrier having a different frequency from that of the carrier used in the direct link and the access link.
