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： A frequency hopping system such as a Bluetooth system (300) can reduce the number of RF channels it hops during a normal hopping sequence cycle providing for a Reduced Hopping Sequence (RHS). A communication unit operating in the system such as the Bluetooth master unit (302) determines if any of the RF channels has interference. If any of the channels has interference, the Bluetooth master sends a message to one or more slave units (304, 306) informing them of which channels will be removed from the hopping sequence due to potential interference problems. The units will then use the new RHS for their transmissions, thus avoiding the interference problems (e.g., both avoiding interference in the system's receivers and avoiding creating interference on frequencies that are already occupied by other neighboring systems).

摘要： The frequency hopping pattern of a first wireless communication device is modified such that each transmission (73) to a second wireless communication device is on a frequency (MSj+1) that the second device's normal frequency hopping pattern specifies for one of the second device's next several transmissions to the first device. This permits the second device to make quality measurements (54) on a frequency that the second device will soon use (51) for transmission to the first device.
