1. A method in a base station for wireless communications, comprising:
transmitting K1 radio signals in a first reference time window;
receiving K1 HARQ feedbacks; and
performing Q1 energy detections respectively in Q1 time sub-pools on a first frequency sub-band, the energy detections are energy detections for LBT;
wherein the K1 HARQ feedbacks are respectively used for determining whether the K1 radio signals are correctly received; a first radio signal is one radio signal of the K1 radio signals, the first radio signal carries part of bits comprised by a first bit block; a first HARQ feedback is used for determining whether the first radio signal is correctly received, HARQ feedback(s) other than the first HARQ feedback among the K1 HARQ feedbacks is(are) used for determining the Q1 time sub-pools, both the K1 and the Q1 are positive integers greater than 1; the first frequency sub-band is a carrier or the first frequency sub-band is composed of frequency-domain resources occupied by a positive integer number of Physical Resource Blocks (PRBs) in frequency domain.
