1. A method of vehicle-to-everything (V2X) communication in New Radio (NR), comprising:
receiving, by a processor of an apparatus implemented in a first user equipment (UE), a first signaling from a network node of a wireless network, the first signaling semi-statically pre-configuring a set of sidelink resources within a resource pool for a sidelink between the first UE and a second UE;
transmitting, by the processor, a packet or transport block (TB) to the second UE on the sidelink using a first sidelink resource selected by the first UE from the semi-statically pre-configured set of sidelink resources;
receiving, by the processor, a second signaling from the network node responsive to the second UE failing to decode the packet or TB, the second signaling dynamically configuring a second sidelink resource for the sidelink;
switching, by the processor, from a first mode of operation to a second mode of operation;
retransmitting, by the processor, the packet or TB to the second UE on the sidelink using the dynamically configured second sidelink resource;
receiving, by the processor, scheduling-related information from the second UE via a sidelink control information (SCI) signaling or a medium access control (MAC) control element (CE) signaling; and
retransmitting, by the processor, the packet or TB to the second UE on the sidelink using the dynamically configured second sidelink resource,
wherein the switching comprises:
switching from SCI monitoring to downlink control information (DCI) monitoring for a retransmission configuration; or
switching from the DCI monitoring to the SCI monitoring for the retransmission configuration.
