13. A method in a first node for wireless communications, comprising:
receiving a first signal and a second signal;
determining that there exists an overlapping part in a time domain between time-domain resources occupied by a first radio resource block and time-domain resources occupied by a second radio resource block; and
transmitting a first bit block and a second bit block in a third radio resource set;
wherein the first bit block and the second bit block are respectively used to indicate whether a bit block carried by the first signal and a bit block carried by the second signal are correctly received; the first radio resource block and the second radio resource block are respectively reserved for transmitting the first bit block and the second bit block; the overlapping part of the first radio resource block and the second radio resource block in a time domain comprises K1 multicarrier symbol(s), and time-domain resources occupied by the third radio resource set are related to K1; K1 is a positive integer:
when K1 is greater than a first integer, the third radio resource set is the second radio resource block, and the first bit block and the second bit block are used together to generate a target signaling; the target signaling is transmitted in the third radio resource set;
when K1 is not greater than the first integer, the third radio resource set comprises the first radio resource block and a third radio resource block, time-domain resources occupied by the third radio resource block are a part of time-domain resources occupied by the second radio resource block being orthogonal to time-domain resources occupied by first radio resource block; the first bit block is transmitted in the first radio resource block, and the second bit block is transmitted in the third radio resource block; the first bit block generates a third signal, and the third bit block generates a fourth signal;
an Resource Element (RE) occupied by the third signal and an RE occupied by the fourth signal are orthogonal;
a code rate adopted by the fourth signal is lower than a code rate adopted when the first bit block is transmitted in the second radio resource block; or
a Modulation and Coding Scheme (MCS) adopted by the fourth signal is lower than an MCS adopted when the first bit block is transmitted in the second radio resource block; or
the second bit block is used to generate L1 modulation symbol(s), and a number of REs occupied by the third radio resource block other than REs used for transmitting an RS is equal to L1; or
the second bit block is used to generate L2 modulation symbol(s), and a number of REs occupied by the third radio resource block other than REs used for transmitting an RS is equal to L1, L1 is less than L2, and the L2 modulation symbol(s) is (are) mapped onto the L1 RE(s) by means of puncturing.
