1. A configuration method, applied to a second communication node and comprising:
configuring a corresponding spreading code sequence for each first communication node; and
sending the spreading code sequence to the each first communication node, wherein the spreading code sequence is configured to be used by the each first communication node to process first to-be-transmitted data or received second data;
wherein configuring the corresponding spreading code sequence comprises one of the following:
jointly encoding the spreading code sequence and a time domain resource allocation (TDRA) table;
configuring a new spreading code indication signaling, wherein the new spreading code indication signaling indicates the corresponding spreading code sequence;
configuring a new spreading code indication field in a current signaling, wherein the new spreading code indication field indicates the corresponding spreading code sequence;
configuring a spreading code sequence table and a corresponding spreading code indication signaling, wherein the corresponding spreading code indication signaling comprises indication information configured to indicate the corresponding spreading code sequence in the spreading code sequence table; or
configuring the spreading sequence table and configuring a corresponding spreading code indication field in a current signaling, wherein the corresponding spreading code indication field comprises indication information configured to indicate the corresponding spreading code sequence in the spreading code sequence table.
