The method includes: A first communication apparatus receives first information, where the first information indicates a determining threshold of a parameter in a first parameter set, and the first parameter set includes at least one of the following parameters: location information, delay information, a timing advance rate, a rate of the timing advance rate, a Doppler value, a Doppler rate, and remaining coverage time.

Abstract: A first communication apparatus receives first data, and obtains second data and third data from the first data. The first data includes a first transport block. The first transport block includes the second data and the third data. The second data is mapped to an rth time domain symbol in a first slot. The third data is mapped to an sth time domain symbol in a second slot. r and s are positive integers, and r is not equal to s. Because data in a same transport block is discretized to two different time domain symbols in at least two slots for transmission, when a slot is affected by channel blocking in a data transmission process, only a part of data of one transport block is mapped to the slot.
