Abstract:
1. A method implemented by a base station of transmitting scheduling information associated with a data packet transmitted to a user terminal over a downlink shared channel to reduce false ACK detection in mobile communication systems, said method comprising: determining whether a user terminal is expected to use a first uplink channel or a second uplink channel for sending acknowledgements of data packets transmitted to the user terminal on the downlink shared channel; transmitting the scheduling information from said base station to said user terminal with normal reliability if the user terminal is expected to use the first uplink channel for sending said acknowledgements; and transmitting the scheduling information from said base station to said user terminal with enhanced reliability if the user terminal is expected to use the second uplink channel for sending said acknowledgements, wherein transmitting the scheduling information from said base station to said user terminal with normal reliability comprises transmitting said scheduling information with a selected aggregation level selected to achieve a desired error rate.
