Abstract
Wireless communication between a first transmitter and a first receiver for a new transmission is established on the same wireless data channel used for ongoing transmission between a second transmitter and a second receiver. This is achieved by determining if the second receiver can receive signals from the first transmitter, and determining if the first receiver can receive signals from the second transmitter. If the second receiver cannot receive signals from the first transmitter, and the first receiver cannot receive signals from the second transmitter, then a new transmission is performed from the first transmitter to the first receiver by spatial reuse of the wireless data channel at least partially concurrently with the ongoing transmission on the data channel.
