Abstract
The present disclosure relates to an electronic apparatus, a wireless communication device, and a wireless communication method. According to an embodiment, the electronic device for a base station side comprises a processing circuit. The processing circuit is configured to: perform control to perform, on a beam corresponding to a user equipment, channel detection on a target channel, the channel detection being based on a specific beam direction; and determine the access to the target channel according the channel detection result.
Claims14
An electronic device for base station side, comprising:
- a processing circuitry configured to:
- perform control to carry out a channel detection based on specific beam direction with respect to a target channel on a beam corresponding to a first user equipment;
- determine an access to the target channel based on a result of the channel detection;
- when the first user equipment exits a range of the beam and a second user equipment enters a range of the beam during a maximum channel occupation time determined with respect to the beam, perform a communication with the second user equipment using the target channel without either the electronic device or the second user equipment performing additional channel detection;
- control a data transmission with the first user equipment on the target channel taking mini-slot as a scheduling unit;
- and
- indicate a setting of the mini-slot by downlink control information of a physical downlink control channel,
- wherein when the downlink control information indicates that one user equipment is scheduled, then the first user equipment performs a data transmission in a predetermined number of following mini-slots, and
- wherein, otherwise, the first user equipment switches to a standby state until next downlink control information.
