Title: Spatial-temporal adaptive equalizing method for interference canceling in wireless communication system
Inventor: PARK JAE HYUN
IPC: H04B7/005
Filed: 2006-11-23
Abstract: A space-time adaptive equalizing method for interference canceling in a wireless communication system is provided to cancel a unknown interference such as multiple cell interference or interference between different users in the same cell in the downlink of a WCDMA(Wideband Code Division Multiple Access) system or an HSDPA(High Speed Downlink Packet Access) system, thereby lowering a BER(Bit Error Rate). Noise and interference have influence on a signal when the signal passes through a wireless channel via a node B. The signal passes through the RF(Radio Frequency)/IF(Intermediate Frequency) block of a receiver, an ADC(Analog to Digital Converter), an RRC(Root-Raised Cosine) filter, and an IC(Integrated Circuit)(10) maximizing an SINR(Signal to Noise Ratio). A unknown noise is cancelled through a channel compensation equalizer(30) and an adaptive interference canceling equalizer. Receiving data is generated by passing through a despreader, a demodulator, a TrCH(Transmission Channel) processor, and a channel decoder. The output signal of the adaptive interference canceling equalizer is transmitted to the despreader and the demodulator.

Filed: 2004-08-03
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.
