Abstract: A radio unit includes: receiver circuitry which, in operation, receives, from each of a first distributed unit and a second distributed unit that control the radio unit, control information regarding resource allocation for uplink for a terminal; and controller circuitry which, in operation, controls, based on the control information, transfer of a received signal in the uplink to either the first distributed unit or the second distributed unit.

Abstract: A base station determines, based on transmission quality information of a fronthaul and channel quality information of a terminal, a resource and a transmission scheme of the fronthaul assigned to the terminal, and controls, based on determined information, the transmission scheme of a signal to be transmitted to the fronthaul using the determined resource.

Abstract: A control device includes reception circuitry which, in operation, receives control information regarding resources to be allocated to a plurality of distributed units, and control circuitry which, in operation, determines, based on the control information, a distributed unit to which a received signal of uplink is to be transferred among the plurality of distributed units.

Abstract: A communication control apparatus includes: a storage, which, in operation, stores an offset value of each of parameters of a quality of service (QoS) class identifier (QCI) in association with a property of each of base stations; offset determination circuitry, which, in operation, determines, based on base station identification information included in a request signal that is received, a property of a specific base station that has transmitted the request signal, and determines whether offset of each of the parameters is required for the specific base station based on the property; offset calculation circuitry, which, in operation, calculates an offset value of each of the parameters corresponding to the property of the specific base station when the offset is required; and a transmitter, which, in operation, transmits information indicating the offset value to the specific base station.

Abstract: A communication device includes: receiving circuitry which, in operation, receives a radio signal transmitted by a mobile station; and processing circuitry which, in operation, estimates a position of the mobile station based on a signal waveform profile including information about at least two of a direction of arrival, an arrival time, and a received power of the radio signal.

Abstract: A video distribution method is a video distribution method to be performed by a server that distributes a plurality of videos captured by a plurality of users from different viewpoints to a terminal apparatus. The video distribution method includes distributing, from a server to a terminal apparatus, a first video that is one of a plurality of videos captured by a plurality of users from different viewpoints and that is requested by the terminal apparatus, selecting a second video that is one of the plurality of videos and that is likely to be next requested next time by the terminal apparatus, and starting transmission of the second video to the terminal apparatus during distribution of the first video to the terminal apparatus.
