Disclosed are a method, an apparatus, and a system for performing channel access. In detail, provided are a method including: receiving uplink scheduling information; and when the user equipment has stopped an uplink transmission during the uplink transmission being performed according to the uplink scheduling information, to resume the uplink transmission, performing a second type channel access when a channel sensed by the user equipment is continuously idle after the uplink transmission has been stopped, and performing a first type channel access when the channel sensed by the user equipment is not continuously idle after the uplink transmission has been stopped, wherein the first type channel access comprises performing a random backoff after a channel sensing, and the second type channel access only comprises performing a channel sensing and an apparatus and a system therefor.

Aspects of the disclosure relate to repeater controlled by a base station. The repeater receives control signaling including control information in association with traffic relayed through the repeater, between a first wireless communication device and a second wireless communication device, the repeater obtains a time division duplex state from the control information, obtains a fronthaul-link transmission control indicator (TCI) state index from the control information, obtains an access-link TCI state index from the control information, obtains a time domain resource allocation from the control information, and configures a relay unit of the repeater to communicate the traffic between the first wireless communication device and the second wireless communication device based the control information comprising at least one of: the time division duplex state, the fronthaul-link TCI state index, the access-link TCI state index, and the time domain resource allocation. The base station sends the control signaling to control the repeater.

A user equipment (UE) for performing communication, the UE including a transceiver; and a processor coupled with the transceiver and configured to: control the transceiver to receive a UE capability enquiry, determine UE capability fields, except a frequency division duplexing (FDD) additional UE capability field, a time division duplexing (TDD) additional UE capability field, a frequency range 1 (FR 1) additional UE capability field and a frequency range 2 (FR 2) additional UE capability field, to include values applicable for all duplex modes and frequency ranges, and control the transceiver to transmit UE capability information based on a result of the determination.

System and method for improving the shaving experience by providing improved visibility of the skin shaving area. A digital camera is integrated with the electric shaver for close image capturing of shaving area, and displaying it on a display unit. The display unit can be integral part of the electric shaver casing, or housed in a separated device which receives the image via a communication channel. The communication channel can be wireless (using radio, audio or light) or wired, such as dedicated cabling or using powerline communication. A light source is used to better illuminate the shaving area. Video compression and digital image processing techniques are used for providing for improved shaving results. The wired communication medium can simultaneously be used also for carrying power from the electric shaver assembly to the display unit, or from the display unit to the electric shaver.
