Claim 14:
15. An apparatus implemented as a first user equipment (UE), comprising:
a transceiver configured to wirelessly communicate with a second UE and a network node of a wireless network; and
a processor coupled to the communication device and configured to perform operations comprising:
receiving, via the transceiver, 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, via the transceiver, 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, via the transceiver, 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 from a first mode of operation to a second mode of operation;
retransmitting, via the transceiver, the packet or TB to the second UE on the sidelink using the dynamically configured second sidelink resource;
receiving, via the transceiver, 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, via the transceiver, 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.
