1. A first node for wireless communications, comprising:
a first receiver, executing a first monitoring and a second monitoring; judging whether a first channel and a second channel are available respectively according to the first monitoring and the second monitoring; and
a first transmitter, when the first channel is judged to be available and the second channel is judged to be unavailable, transmitting a target bit block on the first channel; when the second channel is judged to be available, transmitting a target bit block on the second channel;
wherein the first channel overlaps with the second channel in time domain; the second channel occupies K subbands in frequency domain, K being a positive integer greater than 1; when a number of idle subbands on the second channel is less than K1, the second channel is judged to be unavailable, and when a number of idle subbands on the second channel is not less than K1, the second channel is judged to be available; K1 is a positive integer not greater than K; the first monitoring is a Listen Before Talk (LBT), or the first monitoring is a Clear Channel Assessment (CCA); the second monitoring is a Listen Before Talk (LBT), or the second monitoring is a Clear Channel Assessment (CCA); the first channel is for PUCCH transmission, and the second channel is for PUSCH transmission.
