1. A host configured to operate in a communication system to provide an over-the-top (OTT) service, the host comprising:
processing circuitry configured to provide user data; and
a network interface configured to initiate transmission of the user data to a network node in a cellular network for transmission to a user equipment (UE), the network node having a communication interface and processing circuitry configured to perform operations comprising:
determining a Physical Downlink Shared Channel (PDSCH) to Hybrid Automatic Repeat Request (HARQ) timing for an upcoming downlink data transmission to the UE, the upcoming downlink data transmission comprising the user data;
determining that HARQ feedback for the upcoming downlink data transmission should be delayed by the UE until further notification from the network node;
transmitting, to the UE, a first Downlink Control Information (DCI) associated with the upcoming downlink data transmission, the first DCI comprising a first PDSCH-to-HARQ timing-indicator value for indicating to the UE that the HARQ feedback for the upcoming downlink data transmission should be delayed until further notification from the network node;
transmitting a second DCI associated with an additional upcoming downlink data transmission as the further notification, the second DCI comprising a numerical PDSCH-to-HARQ timing indicator; and
transmitting the user data from the host to the UE in the upcoming downlink data transmission and the additional upcoming downlink data transmission to provide the OTT service.
