Document Type and Number:
WIPO Patent Application WO/2021/161474
Kind Code:
A1
Abstract:
The present invention addresses the problem of improving PRR while suppressing control signal traffic for beamforming. In order to solve this problem, a wireless communication device (UE) is, according to one aspect, provided with a transmission unit (113), a reception unit (116), and an identifying unit (115). The transmission unit (113) transmits data to a plurality of other wireless communication devices (UE). The reception unit (116) receives signals transmitted from the other wireless communication devices (UE). When a retransmission request requesting retransmission of data is included in a signal transmitted from one of the other wireless communication devices (UE), the identification unit (115) identifies the location of the other wireless communication device (UE) that was the transmission source of the retransmission request. The transmission unit (113) then retransmits the data by using an electromagnetic wave radiation pattern having directionality in the direction of the location identified by the identification unit (115).
