1. A method at a user equipment (UE), the method comprising:
assigning a first protocol stack of the UE to network communications;
assigning a second protocol stack of the UE to sidelink communications;
generating, at the second protocol stack, first information based on arrival of data in a sidelink logical channel;
transmitting the first information within the UE from the second protocol stack to the first protocol stack; and
transmitting the first information from the first protocol stack to a network device,
wherein the first information comprises information indicating triggering of a buffer status report,
wherein a medium access control layer of the second protocol stack comprises the information indicating the triggering of the buffer status report, and
wherein transmitting the first information form the second protocol stack to the first protocol stack comprises transmitting the first information from the medium access control layer of the second protocol stack directly to a medium access control layer of the first protocol stack.
