2 . The method according to claim 1 , further comprises:
performing transmission with one piece of CSI reduced in size through truncation according to a priority of information content in the one piece of CSI in response to that transmission resources are insufficient for transmitting a first message.
3 . The method according to claim 2 , wherein a priority of the first message is predefined or determined according to a configuration rule.
4 . The method according to claim 2 , wherein in a case that the first message is sidelink messages of a plurality of message types, the transmitting a first message according to a priority of the first message comprises:
sequentially transmitting the sidelink messages of the plurality of message types according to priorities of the plurality of message types.
5 . The method according to claim 4 , wherein the plurality of message types comprise at least two of unicast, groupcast, and broadcast; and
priorities of unicast, groupcast, and broadcast are determined based on a first priority parameter, or priorities of messages of unicast, groupcast, and broadcast are preconfigured.
6 . The method according to claim 5 , wherein the first priority parameter comprises a first priority threshold; and
if a priority value of the highest priority of groupcast or broadcast is smaller than or equal to the first priority threshold, a priority of a message of groupcast or broadcast is higher than priorities of some or all messages of unicast; or
if a priority value of the highest priority of groupcast or broadcast is greater than the first priority threshold, a priority of a message of groupcast or broadcast is lower than priorities of some or all messages of unicast; wherein
a smaller priority value means a higher priority.
7 . The method according to claim 2 , wherein in a case that the first message is an air interface Uu message,
the priority of the first message is determined based on message content; or
the priority of the first message is determined based on a second priority parameter.
8 . The method according to claim 7 , wherein the second priority parameter comprises a second priority threshold; and
if a priority value of the highest priority of a sidelink service of the terminal is smaller than or equal to the second priority threshold, a priority of the CSI is the highest in the first message, or a priority of the CSI is higher than a priority of a second message; or
if a priority value of the highest priority of a sidelink service of the terminal is greater than the second priority threshold, a priority of the CSI is lower than a priority of a third message; wherein
a smaller priority value means a higher priority.
9 . The method according to claim 1 , further comprises:
sequentially transmitting a plurality of pieces of CSI according to priorities of the plurality of pieces of CSI.
10 . The method according to claim 1 , wherein if there are at least two links with a same priority in the plurality of links, messages of the at least two links are sequentially transmitted according to a preset message type based order.
11 . The method according to claim 1 , wherein a first message comprises a sidelink message and a Uu message; and
the sidelink message and the Uu message are the CSI;
at least one of the sidelink message and the Uu message comprises the CSI and the non-CSI message; or
one of the sidelink message and the Uu message comprises the CSI, and the other thereof comprises the non-CSI message.
12 . The method according to claim 11 , wherein priorities of the sidelink message and the Uu message are determined based on a third priority parameter; or
priorities of messages in the sidelink message and the Uu message are preconfigured.
13 . The method according to claim 12 , wherein the third priority parameter comprises a third priority threshold and a fourth priority threshold; and
if a priority value of the highest priority of a sidelink interface is smaller than or equal to the third priority threshold and a priority value of the highest priority of a Uu interface is greater than or equal to the fourth priority threshold, the priority of the sidelink message is higher than the priority of the Uu message; if the priority value of the highest priority of the sidelink interface is greater than the third priority threshold or the priority value of the highest priority of the Uu interface is smaller than the fourth priority threshold, the priority of the sidelink message is lower than the priority of the Uu message; wherein a smaller priority value means a higher priority;
the highest priority of the sidelink interface is the highest priority of to-be-transmitted content on the sidelink interface or the highest priority of active services on the sidelink interface; and
the highest priority of the Uu interface is the highest priority of to-be-transmitted content on the Uu interface or the highest priority of active services on the Uu interface.
14 . A terminal, comprising a memory, a processor, and a program stored in the memory and capable of running on the processor, wherein when the program is executed by the processor, the steps of the transmission processing method are implemented, wherein the method comprises:
transmitting messages of a plurality of links according to a priority of the plurality of links, wherein the plurality of links comprise a first link and a second link, or the plurality of links comprise at least the second link;
wherein the priority of the first link and the second link is determined according to the following rules:
the first link comprises at least one first channel state information (CSI), the priority of the first link is a priority of the at least one first CSI;
the second link comprises at least one first CSI and at least one non-CSI message, the priority of the second link is the highest priority among priorities of the at least one first CSI and the at least one non-CSI message.
15 . The terminal according to claim 14 , wherein the program is further executed by the processor to:
perform transmission with one piece of CSI reduced in size through truncation according to a priority of information content in the one piece of CSI in response to that transmission resources are insufficient for transmitting a first message.
16 . The terminal according to claim 15 , wherein a priority of the first message is predefined or determined according to a configuration rule.
17 . The terminal according to claim 14 , wherein the program is further executed by the processor to:
sequentially transmit a plurality of pieces of CSI according to priorities of the plurality of pieces of CSI.
18 . A non-transitory computer-readable storage medium, wherein the computer-readable storage medium stores a computer program, and when the computer program is executed by a processor, the steps of the transmission processing method are implemented, wherein the method comprises:
transmitting messages of a plurality of links according to a priority of the plurality of links, wherein the
plurality of links comprise a first link and a second link, or the plurality of links comprise at least the second link;
wherein the priority of the first link and the second link is determined according to the following rules:
