Claim Text:
1. A method of facilitating operation of a base station in a cellular wireless communication system, comprising: controlling a wireless device to wirelessly transmit, in a first time slot at a first position in a first transmission subframe, data over a first physical communication channel; receiving, over a backhaul network connection that is different from the first physical communication channel, a control message, a first time period after the first time slot, from a microcell base station indicating whether or not the data was received correctly during the first time slot; and transmitting, to the wireless device, over a second physical communication channel that is different from the first physical communication channel and the backhaul network connection, a response message in a second time slot that is a pre-determined time period after the first time slot, such that i) when the control message is received prior to the second time slot, then the response message includes data reception information in the received control message and ii) when the control message is not received prior to the second time slot, then the response message includes a dummy acknowledgement allowing the wireless device to continue operating in deterministic manner.
