FIELD: communication.
SUBSTANCE: invention relates to a method, an apparatus and a system for transmitting periodic information of an uplink/periodic uplink signals. Said is achieved by receiving signal information on configuration, transmitted by network access device and containing configuration parameter of periodic information of uplink/periodic uplink signal, determining a target transmission unit according to said configuration parameter and transmitting or canceling transmission of the periodic uplink/target periodic uplink signal according to the number of uplink symbols in the target transmission block. At that transmission of target periodic information of an uplink/target periodic uplink signal is canceled, when the number of uplink symbols in the target transmission block is less than the second threshold value.
EFFECT: technical result is increase in the probability that the terminal device effectively transmits as feedback periodic information of the uplink/periodic signal of the uplink.
