摘要： A probe, listen and select (PLS) technique can be used to select from an available frequency spectrum a frequency band whose communication quality is suitable for wireless communication at a desired rate. Probe packets can be transmitted on different frequencies (223) during a known period of time (TPLS), and frequency channel quality information can be obtained (225) from the probe packets. This quality information can then be used to select a desirable frequency band (227). The communication quality of the selected band can also be used as basis for selecting (141) from among a plurality of modulation and coding combinations that are available for use in communications operations.

摘要： The present invention provides an apparatus, system and method for removal of interference due to multi-path for multiple transmit antennas (hereinafter referred to as MTA-MPIC) for High Speed Downlink Packet Access (HSDPA) encoded for transmit diversity, such as Space-Time Transmit Diversity (STTD). For a single receive antenna, the signal is received (25) and each multi-path delayed signal is demodulated (21). The demodulation can include long code removal and despreading. Subsequently, each demodulated signal is received by the RAKE receiver (22) for determining the channel estimate and channel normalization for the total HSDPA signal, and for computing space-time decoding for the HSDPA signal. Following the space-time decoding, a data decision is made (23). Next, reconstructed interference signals are generated (24) and combined with the received signal (25). For other user signals, an interference estimate is made from the despreader (322) outputs without applying the RAKE/space-time coding operations.
