An information transmission method, wherein the method comprises: performing (S304), by a transmit end, rate matching on a first bit sequence based on beam indication information, to obtain a second bit sequence, wherein the first bit sequence is a bit sequence obtained by performing channel coding on an original bit sequence; mapping (S311), by the transmit end, the second bit sequence onto a time-frequency resource; and sending (S313), by the transmit end, to a receive end by using a beam indicated by the beam indication information, the second bit sequence that is mapped onto the time-frequency resource; characterised in that the performing (S304) rate matching on a first bit sequence based on beam indication information, to obtain a second bit sequence comprises: obtaining (M1), by the transmit end, the second bit sequence according to the formula e k = w ( j + k 0 )mod K w , wherein e k represents the k th element in the second bit sequence, k is an integer, w ( j + k 0 )mod K w represents the ( j + k 0 )mod K w th element in the first bit sequence, k is in one-to-one correspondence with j, k 0 represents a value related to the beam indication information, and K W represents a length of the first bit sequence; wherein k=0, 1, ..., E-1, k<E, and w ( j + k 0 )mod K w ≠< NULL > , E being determined by an aggregation level, the aggregation levels being 1, 2, 4, and 8 and the respective values of E being 72, 144, 288, and 576. performing (S304), by a transmit end, rate matching on a first bit sequence based on beam indication information, to obtain a second bit sequence, wherein the first bit sequence is a bit sequence obtained by performing channel coding on an original bit sequence; mapping (S311), by the transmit end, the second bit sequence onto a time-frequency resource; and sending (S313), by the transmit end, to a receive end by using a beam indicated by the beam indication information, the second bit sequence that is mapped onto the time-frequency resource; characterised in that the performing (S304) rate matching on a first bit sequence based on beam indication information, to obtain a second bit sequence comprises: obtaining (M1), by the transmit end, the second bit sequence according to the formula e k = w ( j + k 0 )mod K w , wherein e k represents the k th element in the second bit sequence, k is an integer, w ( j + k 0 )mod K w represents the ( j + k 0 )mod K w th element in the first bit sequence, k is in one-to-one correspondence with j, k 0 represents a value related to the beam indication information, and K W represents a length of the first bit sequence; wherein k=0, 1, ..., E-1, k<E, and w ( j + k 0 )mod K w ≠< NULL > , E being determined by an aggregation level, the aggregation levels being 1, 2, 4, and 8 and the respective values of E being 72, 144, 288, and 576. obtaining (M1), by the transmit end, the second bit sequence according to the formula e k = w ( j + k 0 )mod K w , wherein e k represents the k th element in the second bit sequence, k is an integer, w ( j + k 0 )mod K w represents the ( j + k 0 )mod K w th element in the first bit sequence, k is in one-to-one correspondence with j, k 0 represents a value related to the beam indication information, and K W represents a length of the first bit sequence; wherein k=0, 1, ..., E-1, k<E, and w ( j + k 0 )mod K w ≠< NULL > , E being determined by an aggregation level, the aggregation levels being 1, 2, 4, and 8 and the respective values of E being 72, 144, 288, and 576. <EOS>
