1. A method in a User Equipment (UE) for wireless communication, comprising:
receiving first information from a base station device; and
monitoring a first signaling in M Resource Element (RE) sets, the first signaling being transmitted by the base station device, the first signaling is DCI (Downlink Control Information), the first signaling is transmitted through a PDCCH (Physical Downlink Control Channel);
wherein:
the first information is used by the UE for determining the M RE sets, the monitoring of the first signaling assumes that P modulation symbol groups are one-to-one mapped to PRE sets, the PRE sets are PRE sets out of the M RE sets, and one blind detection for the first signaling is performed on the PRE sets;
bits in a first bit sequence of the first signaling have been modulated by the base station device to obtain modulation symbols that constitute a first modulation symbol set sequentially,
wherein the bits in the first bit sequence are sequentially arranged according to an output of a channel encoder, each modulation symbol in the first modulation symbol set is modulated based on Quadrature Phase Shift Keying (QPSK), the channel encoder is based on polar coding;
the first modulation symbol set is divided into the P modulation symbol groups successively from a front modulation symbol to a rear modulation symbol in the first modulation symbol set, and each modulation symbol group of the P modulation symbol groups consists of X modulation symbols; and
relative positions of the PRE sets in frequency domain are related to at least one of {M, X},
wherein M is a positive integer, P is a positive integer not greater than M, and X is a positive integer;
X is related to the number of multicarrier symbols occupied by the M RE sets in time domain, the M RE sets occupy one of {1,2,3} multicarrier symbols in time domain, the M RE sets are discrete in frequency domain.
