1. A method in a User Equipment (UE) for low latency, comprising:
receiving a first signaling;
receiving a second signaling; and
receiving a first radio signal on target time-frequency resources;
wherein first time-frequency resources and the target time-frequency resources are orthogonal, or the target time-frequency resources comprise the first time-frequency resources; time-frequency resources among second time-frequency resources other than the first time-frequency resources belong to the target time-frequency resources, and the second signaling is used for determining the first time-frequency resources and the second time-frequency resources; the target time-frequency resources belong to a first time interval in time domain, and the first time interval has a duration less than 1 millisecond; the first radio signal carries a first bit block, the first bit block comprises a positive integer number of bit(s), and the first bit block is transmitted on the target time-frequency resources; the first signaling is used for determining a first resource pool, the first resource pool comprises the first time-frequency resources, and the first resource pool is reserved to downlink physical layer signaling(s); the second signaling includes scheduling information of the first radio signal, and the scheduling information includes at least one of a Resource Allocation (RA), a Modulation and Coding Scheme (MCS), a New Data Indicator (NDI), a Redundancy Version (RV) and a HARQ process number; the first time interval includes R consecutive time-domain OFDM symbols, the OFDM symbols include cyclic prefixes, and R is a positive integer, the first time-frequency resources belong to the first time interval in time domain, the second signaling is transmitted in the first time interval.
