Abstract
The present disclosure provides a signal transmission/reception method, user equipment, and network equipment, the method including: determining, by a user equipment, an available random access occasion and a timing advance (TA) value; performing listen before talk (LBT) before a TA of the first available random access occasion; transmitting, if the LBT is successful, the random access preamble on the random access occasion.
Claims15
A method of transmitting and receiving a signal, by a UE (user equipment), the method comprising:
- determining an available random access occasion and a timing advance (TA) value;
- performing listen before talk (LBT) before a TA of the first available random access occasion;
- and
- transmitting, if the LBT is successful, the random access preamble on the random access occasion.
A method of transmitting and receiving a signal, by a base station, the method, comprising:
- determining a time-frequency resource and/or a timing advance value of an available uplink signal;
- and
- detecting and receiving a possible uplink signal on a time-frequency resource of the configured uplink signal.
A UE (user equipment) of transmitting and receiving a signal, the UE comprising:
- a transceiver;
- and
- a processor coupled with the transceiver and configured to:
- determine an available random access occasion and a timing advance (TA) value,
- perform listen before talk (LBT) before a TA of the first available random access occasion, and
- control the transceiver to transmit, if the LBT is successful, the random access preamble on the random access occasion.
A base station of transmitting and receiving a signal, the base station comprising:
- a transceiver;
- and
- a processor coupled with the transceiver and configured to:
- determine a time-frequency resource and/or a timing advance value of an available uplink signal, and
- detect a possible uplink signal on a time-frequency resource of the configured uplink signal and
- control the transceiver to receive the detected uplink signal.
