1. A method for sending sidelink data, comprising:
multiplexing, by a first user equipment (UE) in a Vehicle to Everything, sidelink data respectively corresponding to at least two sidelink identifiers of a second UE to a same Medium Access Control Protocol Data Unit (MAC PDU), and sending, by the first UE, the MAC PDU to the second UE,
wherein each sidelink identifier respectively corresponds to one or more logic channels of the second UE;
wherein multiplexing the sidelink data respectively corresponding to the at least two sidelink identifiers of the second UE to the same MAC PDU and sending the MAC PDU to the second UE comprises:
acquiring a first sidelink data, wherein the first sidelink data is to-be-sent data corresponding to a first sidelink identifier of a first highest priority logic channel, and the first highest priority logic channel is a logic channel corresponding to the second UE;
determining a time-frequency resource used for sending the first sidelink data;
adding the first sidelink data to the MAC PDU;
acquiring a second sidelink data in response to determining that a bearable data volume of the time-frequency resource is greater than a data volume of the MAC PDU, wherein the second sidelink data is to-be-sent data corresponding to a second sidelink identifier of a second highest priority logic channel among other logic channels of the second UE;
adding the second sidelink data to the MAC PDU; and
sending the MAC PDU to the second UE using the time-frequency resource.
