ABSTRACT:
A base station (BS) (110) in a wireless network (100) establishes power levels for transmitting messages acknowledging receipt of packet data from a mobile communications device (MCD) (114). In one implementation, the BS infers whether the MCD received a given acknowledgement message by considering whether (306, 316) the next communication from the MCD comprises new packet data, and whether (310, 320) that data comprises re-transmitted data. The BS adjusts (312, 314, 322, 324) transmit power level for future acknowledgement messages according to whether the MCD received past acknowledgement messages. In a different implementation, actual/estimated transmit power from a serving base station to a given MCD is averaged (404), and increased (406) by a prescribed amount to yield a target level. Whenever the non-serving base station transmits messages acknowledging receipt of packet data from the MCD, the non-serving base station transmits (408) at the target level.
