1. A method for indicating sidelink transmission resources, comprising:
selecting N transmissions according to a target indication rule, and determining N transmission resources of data information of a data packet corresponding to the N transmissions as selected, where N is a maximum quantity of transmissions that control information for indicating transmission resources is capable of indicating, N is less than M, M is a total quantity of transmissions of the data information of the data packet, the M transmissions of the data information of the data packet comprises an initial transmission and M−1 retransmissions, and N is an integer greater than or equal to 2; and
transmitting, in the control information, information for indicating the N transmission resources as determined;
wherein the N transmissions as selected comprises a current transmission, and N−1 transmissions selected from the current transmission according to a continuous sequential cycle rule, or an odd-even cycle rule, or a preset cycle rule; or,
the N transmissions as selected comprises a current transmission, and N−1 transmissions selected from the current transmission according to a continuous sequential rule, or an odd-even rule, or a preset rule;
wherein the continuous sequential cycle rule comprises:
selecting in sequence, starting from the current transmission and according to serial numbers of transmissions; and
skipping to a first one of the transmissions in response to determining that a last one of the transmissions has been selected, and selecting again in sequence, starting from the first one of the transmissions and according to the serial numbers of the transmissions;

or,
wherein the odd-even cycle rule comprises:
selecting in sequence, starting from the current transmission and according to serial numbers of odd-numbered transmissions; and
skipping to a first one of the odd-numbered transmissions in response to determining that a last one of the odd-numbered transmissions has been selected, and selecting again in sequence, starting from the first one of the odd-numbered transmissions and according to the serial numbers of the odd-numbered transmissions; or,
the odd-even cycle rule comprises:

selecting in sequence, starting from the current transmission and according to serial numbers of even-numbered transmissions; and
skipping to a first one of the even-numbered transmissions in response to determining that a last one of the even-numbered transmissions has been selected, and selecting again in sequence, starting from the first one of the even-numbered transmissions and according to the serial numbers of the even-numbered transmissions;

or,
wherein the preset cycle rule comprises:
selecting one or more transmissions, staring from the current transmission to a last one of the transmissions and according to a first rule; and
skipping to a first one of the transmissions that satisfies a second rule in response to determining that a last one of the transmissions that satisfies the first rule has been selected, and
selecting one or more transmissions, starting from the first one of the transmissions that satisfies the second rule and according to the second rule,
wherein the first rule comprises selecting in sequence according to serial numbers of the transmissions, or, selecting in sequence according to the serial numbers of transmissions whose serial numbers modulo N1 evaluate to M1, and wherein the second rule comprises selecting in sequence according to the serial numbers of the transmissions, or, selecting in sequence according to the serial numbers of transmissions whose serial numbers modulo N2 evaluate to M2, where N1, N2, M1 and M2 are integers, N1>M1, and N2>M2;

or,
wherein the continuous sequential rule comprises:

selecting in sequence, starting from the current transmission and according to serial numbers of odd-numbered transmissions or serial numbers of even-numbered transmissions;

or,
wherein the preset rule comprises:
selecting one or more transmissions, staring from the current transmission to a last one of the transmissions and according to a first rule, the first rule comprises selecting in sequence according to serial numbers of the transmissions, or, selecting in sequence according to the serial numbers of transmissions whose serial numbers modulo N1 evaluate to M1, where N1 and M1 are integers.

2. The method according to claim 1 , wherein, before selecting the N transmissions according to the target indication rule, the method further comprises:
receiving a preset indication rule transmitted by a network side, wherein the preset indication rule comprises one or more indication rules; and
selecting one indication rule from the preset indication rule as the target indication rule.

3. The method according to claim 2 , wherein in response to determining that the preset indication rule comprises a plurality of indication rules, when transmitting, in the control information, information for indicating the N transmission resources as determined, the method further comprises:
transmitting, in the control information, indication information for indicating the target indication rule currently adopted by a node.

4. The method according to claim 1 , wherein the transmission resources of the data information comprise a time-domain resource of the data information and a frequency-domain resource of the data information.

5. A device for indicating sidelink transmission resources, comprising:
a processor; and
a transceiver, configured to transmit and receive data under control of the processor,
wherein the processor is configured to:
select N transmissions according to a target indication rule, and determine N transmission resources of data information of a data packet corresponding to the N transmissions as selected, where N is a maximum quantity of transmissions that control information for indicating transmission resources is capable of indicating, N is less than M, M is a total quantity of transmissions of the data information of the data packet, the M transmissions of the data information of the data packet comprises an initial transmission and M−1 retransmissions, and N is an integer greater than or equal to 2; and
