The configuration method includes configuring a corresponding spreading code sequence for each first communication node and sending the corresponding spreading code sequence to each first communication node. The spreading code sequence is configured to be used by the first communication node to process first to-be-transmitted data or received second data.

First claim

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.

2. The method according to claim 1 , wherein jointly encoding the spreading code sequence and the TDRA table comprises one of the following:
configuring the corresponding spreading code sequence in the TDRA table; or
configuring a spreading code sequence table and configuring index information in the TDRA table, wherein the index information is configured to indicate the corresponding spreading code sequence in the spreading code sequence table.

3. The method according to claim 1 , further comprising:
configuring a correspondence between a length of the spreading code sequence and a number of different elements in a redundancy version (RV) sequence; and
configuring a correspondence between spreading code sequences of different first communication nodes and a plurality of identical elements in the RV sequence.

4. The method according to claim 1 , further comprising:
configuring a delay signaling, wherein the delay signaling is configured to indicate a delay of a nominal repeated transmission and a start position of a delayed transmission resource in response to a subframe boundary or an uplink-downlink (U/D) switching point occurring in a nominal repeated transmission resource of the first communication node.

5. The method according to claim 1 , wherein the spreading code sequence is further configured to instruct the first communication node to delay a position of a nominal repeated transmission to a nearest transmissible resource of the nominal repeated transmission in response to a subframe boundary or a U/D switching point occurring in a nominal repeated transmission resource of the first communication node, wherein a position of the nearest transmissible resource is not allowed to exceed a pre-configured time window.

6. The method according to claim 1 , further comprising:
processing second to-be-transmitted data based on the spreading code sequence to obtain the second data; and
sending the second data to the first communication node.

7. The method according to claim 1 , further comprising:
receiving first data sent by the first communication node, wherein the first data is obtained from the first to-be-transmitted data processed by the first communication node; and
in response to a repeated transmission occurring between a plurality of first communication nodes, processing the first data based on the spreading code sequence.

8. The method according to claim 6 , wherein in response to a length of the spreading code sequence being greater than a number of transmission repetitions, first N bits of the spreading code sequence are intercepted and are used as the spreading code sequence, wherein N denotes the number of transmission repetitions; or

9. A data processing method, applied to a first communication node and comprising:
receiving a spreading code sequence sent by a second communication node, wherein the spreading code sequence is configured and sent by the second communication node; and
processing first to-be-transmitted data or received second data based on the spreading code sequence, wherein the received second data is obtained by processing second to-be-transmitted data by the second communication node;
wherein the spreading code sequence is configured by the second communication node in one of the following manners:
the second communication node jointly encodes the spreading code sequence and a time domain resource allocation (TDRA) table;
the second communication node configures a first spreading code indication signaling, wherein the first spreading code indication signaling comprises the spreading code sequence;
