Abstract
Methods and apparatuses for transmitting and receiving uplink signals. The method for transmitting includes: receiving by a terminal equipment a first signal transmitted by a network device, the first signal being at least used for the terminal equipment to determine whether to perform channel detection and/or how to perform channel detection before transmitting a second signal; and transmitting the second signal by the terminal equipment to the network device by using an uplink resource.
Claims20
An apparatus for transmitting an uplink signal, configured in a terminal equipment, the apparatus comprising:
- a receiver configured to receive a radio resource control (RRC) message;
- a transmitter configured to transmit an uplink transmission;
- and
- a processor configured to:
- control, when the received radio resource control message does not include first information, to not perform channel access procedure for transmitting the uplink transmission, and
- control, when the received radio resource control message includes the first information, to performs channel access procedure for transmitting the uplink transmission.
An apparatus for receiving an uplink signal, configured in a network device, the apparatus comprising:
- a transmitter configured to transmit a radio resource control (RRC) message;
- and
- a receiver configured to receive an uplink transmission transmitted by a terminal equipment by using an uplink resource;
- wherein,
- when the received radio resource control message does not include first information, the terminal equipment does not perform channel access procedure for transmitting the uplink transmission, and
- when the received radio resource control message includes the first information, the terminal equipment performs channel access procedure for transmitting the uplink transmission.
A communication system, comprising:
- a network device configured to:
- transmit a radio resource control (RRC) message signal, and
- receive an uplink transmission;
- and
- a terminal equipment configured to:
- receive the radio resource control message signal, transmit the uplink transmission,
- wherein,
- control, when the received radio resource control message does not include first information, to not perform channel access procedure for transmitting the uplink transmission, and
- control, when the received radio resource control message includes the first information, to performs channel access procedure for transmitting the uplink transmission.
