  • Publication number: 20190357208
    Abstract: A self-contained subframe configuration method includes obtaining configuration information of a self-contained subframe of a current frequency band based on a subframe transmission direction of a neighboring frequency band. The self-contained subframe includes a downlink control (DLcontrol) field, a first transmission subframe, a second transmission subframe, a guard period (GP), and an uplink control (ULcontrol) field. The first transmission subframe or the second transmission subframe of the self-contained subframe is transmitted in the same subframe transmission direction used during subframe transmission on the neighboring frequency band. Alternatively, the first transmission subframe or the second transmission subframe of the self-contained subframe is transmitted in a guard period of the neighboring frequency band.

  • Publication number: 20190357177
    Abstract: In the embodiments of the present invention, a base station can determine a relay communication period of remote user equipment by using indication information carried in a resource request of relay user equipment or by using a resource request of the remote user equipment, and allocate a resource in the relay communication period to the relay user equipment, so that the relay user equipment returns a response message to the remote user equipment by using the resource. Therefore, for a request message sent by the remote user equipment, it can be ensured that the relay user equipment returns, in the relay communication period, a response message corresponding to the request message to the remote user equipment, to avoid a case in which the remote user equipment cannot detect the response message, and to reduce a failure probability of a service requested by the remote user equipment.

  • Patent number: 10389564
    Abstract: The present invention is designed so that, in a radio communication system in which inter-terminal communication is carried out, the impact of inter-symbol interference due to the delay of inter-terminal discovery signals is reduced. The radio communication method of the present invention is used in a radio communication system in which each user terminal transmits the inter-terminal discovery signal in a transmission duration of a predetermined period. A radio base station determines the cyclic prefix (CP) length configuration for use in the transmission duration, and transmits cyclic prefix (CP) length configuration information which represents the CP length configuration. Each user terminal transmits the inter-terminal discovery signal based on the CP length configuration information.
