Transmit scheduling in multi-radio devices

Abstract:

Technologies transmit scheduling in multi-radio devices are described. One multi-radio device includes first and second radios and a scheduler circuit. The scheduler circuit outputs a first signal to the radios in a first mode in which the first radio is transmitting first data and the second WLAN radio is transmitting second data concurrently. The first signal increases a first clear channel assessment energy detect (CCA-ED) threshold to a second CCA-ED threshold. The scheduler circuit outputs a second signal to the second WLAN radio in a second mode. The second signal causes transmission of fourth data to be delayed until after the first radio completes reception of third data. In a third mode, the scheduler circuit outputs a third signal to the first WLAN radio. The third signal causes transmission of fifth data to be delayed until after the second radio completes reception of sixth data.
