  • Patent number: 11729796
    Abstract: A radio communication system includes a first base station that manages a first cell (110), a second base station (12) that manages a second cell (120), and a radio terminal (2). The radio terminal (2) supports dual connectivity involving a bearer split in which a first network bearer between the radio terminal (2) and a core network (3) is split over the first base station (11) and the second base station (12). The first base station (11) receives, from the second base station (12), bearer split status information about communication of the first network bearer in the second base station (12), and performs control of an access stratum related to the first network bearer. It is thus possible to contribute, for example, to an improvement in control of an access stratum when dual connectivity involving a bearer split is performed.

  • Patent number: 11638241
    Abstract: It is possible to solve the problem that a downstream control information amount is significantly increased if allocation information is periodically reported because no allocation method of a default E-DCH resource configuration is defined for a preamble signature. A base station and a mobile station decide a default resource configuration by using a total number of resource configurations or a value obtained from the total number.

  • Publication number: 20230123167
    Abstract: A radio terminal (3) can perform carrier aggregation using a first cell (10) of a first radio station (1) and a second cell (20) of a second radio station (2). The first radio station (1) or the second radio station (2) transmits constraint information to the radio terminal (3). The constraint information contains an information element necessary to specify a reception constraint and/or transmission constraint related to the first cell (10) and/or the second cell (20) when the carrier aggregation is performed. The reception/transmission constraint is a constraint related to downlink signal reception/uplink signal transmission by the radio terminal over one or more subframe periods of the primary cell (10) and the secondary cell (20). It is thus, for example, possible to contribute to reduction in wasteful power consumption in the radio terminal in the carrier aggregation of a plurality of cells served by different radio stations.
