Wireless communication device and wireless communication method

TL;DR: In this article, a portable P-UE (20) receives a signal transmitted from another UE, specifies a first determination subject signal received from a VUE (10) provided to a vehicle, determines whether there is the first determination-subject signal which satisfies a predetermined condition or not among the reception signals, transmits a signal to the V-UE(10) in the case where there is no first-determinate subject signal that satisfies the predetermined condition.
Patent

User equipment and base station

TL;DR: In this paper, a UE includes a measurer that measures, for each of a plurality of candidate beams, a benchmark pertaining to communication quality; a comparer that compares the benchmark with a first threshold value and a second threshold value; and a feedback unit that transmits the benchmark to the base station as feedback information pertaining to an interference beam if the benchmark is the first threshold values or higher and lower than the second threshold values.
Patent

Wireless communication apparatus and wireless communication method

TL;DR: In this paper, a UE that carries out the Sidelink V2X communication causes: a free resource search unit (105) to search for free resources within a first resource range; a transmission processing unit (107) to transmit a first transmission packet by using the free resources contained within the first resource ranges; and a transmission inhibition timer unit (108) to set transmission inhibition time which is time for inhibiting start of a second resource range after the transmission of the first transmission packets in the first range.
Patent

Server device and communication method

TL;DR: In this article, a server device for determining, on the basis of a communication cost in a communication area, a first terminal to which uplink data is to be transmitted in a first communication area in which the communication cost is less than a threshold.
Patent

Wireless terminal device and communications method

TL;DR: In this article, a wireless terminal device consisting of a storage unit that holds connection ID mapping information having associated therein a connection ID and at least one logical connection destination, a communications unit that receives control information including the connection ID, and communications control information for the logical connection destinations, and a control unit that specifies a logical link destination corresponding to the connection IDs included in the control information received by the communications unit, and performs processing on the specified logical link destinations on the basis of the communications control.
