1. A method for implementing beam scanning and communication under a condition that there is no beam pairing between a first node and a second node, and the method comprises:
under the condition that there is no beam pairing between the first node and the second node, sending, by the first node in an i-th transmission, P first transmission blocks on M1 time-frequency resources using a first beam group comprising N1 beams to the second node, wherein the P first transmission blocks are obtained based on a second transmission block and are in a same coding redundancy version or different coding redundancy versions, and the i, M1, N1 and P are integers greater than or equal to 1, and the P first transmission blocks are data for communication;
determining, by the first node, a second beam group and Q third transmission blocks for a (i+1)-th transmission according to whether feedback information or a transmission failure identifier is received, wherein the Q third transmission blocks are data for communication; and
wherein the determining, by the first node, the second beam group and the Q third transmission blocks for the (i+1)-th transmission according to whether the feedback information or the transmission failure identifier is received comprises:
in response to the feedback information being not received by using any beam in the first beam group, determining that the second beam group for the (i+1)-th transmission is the first beam group, and determining that the Q third transmission blocks are transmission blocks obtained based on the second transmission block and in a same coding redundancy version or different coding redundancy versions, and coding redundancy versions corresponding to the Q third transmission blocks being identical to or different from coding redundancy versions corresponding to the P first transmission blocks;
in response to the feedback information or the transmission failure identifier being received by using beams in the first beam group, sending, by the first node, the Q third transmission blocks on M2 time-frequency resources by using the second beam group for the (i+1)-th transmission to the second node, wherein the M2 and Q are integers greater than or equal to 1.
