LOW LATENCY HYBRID AUTOMATIC REPEAT REQUEST (HARQ) FEEDBACK FOR WIRELESS NETWORKS
An example implementation includes determining, by a user device, that the user device is a low-latency mode user device; receiving a downlink data block in downlink subframe n; determining a hybrid automatic repeat request (HARQ) feedback for the data block; determining, by the low-latency mode user device, an uplink subframe n+k at a HARQ feedback offset of k subframes from subframe n, and one or more uplink HARQ resources for the uplink subframe n+k reserved for the HARQ feedback from the low-latency mode user device; and transmitting, by the low-latency mode user device, the HARQ feedback via subframe n+k and the one or more uplink HARQ resources.
