Abstract
When a UE is being served by a base station over a first air interface in a client-server relationship and the UE receives from the base station a HARQ NACK for a transmission over the first air interface, the UE will responsively engage in the HARQ re-transmission to the base station over a second, different air interface, such as through a peer-to-peer communication to the base station. The first air interface may be an OFDMA air interface such as LTE, and the second air interface may be a WLAN air interface such as WiFi. Engaging in re-transmission via the second air interface may enable the base station to complete receipt of the data from the UE and thereby provide the UE, via the first air interface, with a HARQ ACK. This arrangement may help reduce delay in re-transmission, which may be particularly useful for delay-sensitive communications such as VoIP communications.
