1. A User Equipment (UE) for wireless communication, comprising:
a first receiver, to receive first information; and
a first transceiver, to transmit a first radio signal using a first antenna port group;
wherein the first information is used for indicating a first offset set, and the first offset set comprises K1 first-type offsets;
time domain resources occupied by the first radio signal start from a first time, a time interval between the first time and a second time is equal to a target offset, and the target offset is one of the K1 first-type offsets;
the UE selects the target offset from the K1 first-type offsets autonomously;
the second time is a start time of a first time window;
time domain resources occupied by the first radio signal belong to the first time window;
the first antenna port group is related to the first offset set;
the first antenna port group comprises a positive integer number of antenna ports;
and the first information is transmitted through an air interface;
the K1 is a positive integer;
the first radio signal occupies a partial of one multicarrier symbol and a positive integer number of complete multicarrier symbols successively in time domain, and the partial of one multicarrier symbol occupied by the first radio signal is a cyclic extension of an earliest complete multicarrier symbol occupied by the first radio signal;
wherein, the UE selecting the target offset from the K1 first-type offsets autonomously refers to:
the UE randomly selecting one first-type offset from the K1 first-type offsets as the target offset;
the first radio signal is transmitted on a Physical Uplink Shared Channel.
