1. A method in a User Equipment (UE) for low-latency communication, comprising:
transmitting Q piece(s) of indication information; and
transmitting a first reference signal and a first radio signal on a first carrier;
wherein the first radio signal carries at least one of a first bit block and first uplink control information; the first radio signal is transmitted by a first antenna port group; the first antenna port group comprises P antenna port(s), P being a positive integer; the first reference signal comprises P reference signal port(s), and the P reference signal port(s) is(are) transmitted by the P antenna port(s) respectively; the first radio signal comprises L radio sub-signals, and the L radio sub-signals occupy L time intervals respectively, the L being a positive integer greater than 1; the Q piece(s) of indication information is(are) used for determining ratios of transmit powers of the first radio signal to transmit powers of the first reference signal in Q time interval(s) respectively; the Q time interval(s) is(are) one(Q ones) of the L time intervals; and the Q is a positive integer less than or equal to the L.
