1. A method performed by a first device configured to operate in a communication system, the method comprising:
receiving, from a network, one or more first grants for transmission to a second device;
creating a data unit for transmission to the second device;
performing a first transmission of the data unit to the second device by based on the one or more first grants;
after identifying that no acknowledgement for the first transmission is received from the second device, determining whether to transmit, to the network via a resource for uplink control channel, a resource request for a second transmission of the data unit based on a required delay of the data unit, wherein the second transmission is a retransmission for the first transmission;
transmitting, to the network via the resource for uplink control channel, the resource request for the second transmission of the data unit based on the resource for uplink control channel being within a threshold time earlier than the required delay from the first transmission;
receiving, from the network, one or more second grants for transmission to the second device; and
performing the second transmission of the data unit to the second device based on the one or more second grants.
