Claim of US Patent No. 10,568,051

1. A method in a User Equipment (UE) for low latency communication, comprising:determining a first power and transmitting a first radio signal with a first power on a first carrier; and
determining R power value(s) and transmitting R low latency radio signal(s) with R power value(s) respectively on a second carrier;
wherein for any given power of the R power value(s), if a given ideal power is lower than or equal to a first reserved power, the given power is equal to the given ideal power; if the given ideal power is greater than a first reserved power, the given power is greater than or equal to the first reserved power; the given ideal power is a transmitting power of a given low latency radio signal without power scaling, the given low latency radio signal is a low latency radio signal corresponding to the given power in the R low latency radio signal(s); the first radio signal carries either a first bit block or first uplink control information or both of them; the first radio signal comprises L sub-radio signals, and the L sub-radio signals occupy L time intervals respectively, L is a positive integer greater than 1; time domain resources occupied by the R low latency radio signal(s) belong to R time interval(s) respectively, the R time interval(s) is(are) R of the L time intervals, R is a positive integer; the low latency radio signal carries at least a low latency bit block or low latency uplink control information; target time interval set comprises L1 time interval(s), the L1 time interval(s) is(are) L1 of the L time intervals, L1 is a positive integer lower than or equal to L; at least a first time interval of the R time interval(s) belongs to the target time interval set; the R low latency radio signal(s) comprises(comprise) a first low latency radio signal, a transmitting power of the low latency radio signal is a second power, the first power is used for determining the second power or the second power is used for determining the first power; time domain resources occupied by the first low latency radio signal belong to a first time interval; or the R time interval(s) is(are) out of the target time interval set, the first power is used for determining the R power value(s); the first time interval is one of the R time interval(s).
