Method and device in ue and base station used for dynamic scheduling

A method in a base station device for wireless communications, comprising:

• transmitting first information to a User Equipment (UE);
• and
• transmitting, to the UE, a first signaling in M RE sets;
• wherein:
• the first information is used by the UE for determining the M RE sets, a monitoring of the first signaling by the UE assumes that P modulation symbol groups are one-to-one mapped to P RE sets, the P RE sets are P RE sets out of the M RE sets, and one blind detection for the first signaling is performed on the P RE sets;
• bits in a first bit sequence are 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;
• the first modulation symbol set is divided into the P modulation symbol groups successively from the front to the rear, and each modulation symbol group of the P modulation symbol groups consists of X modulation symbols;
• and
• relative positions of the P RE sets in frequency domain are related to the X, wherein the M is a positive integer greater than 1, the P is a positive integer not greater than the M, the P is greater than 1, and the X is a positive integer greater than 1;
• each RE set of the M RE sets consists of 2, 3, or 6 Resource Element Groups(REGs), wherein each REG occupies one multicarrier symbol in time domain and occupies one PRB in frequency domain;
• each RE set of the M RE sets includes the same number of RS REs;
• a first RE set is one of the M RE sets, the REs in the first RE set adopt the same precoding.
