摘要
: The invention pertains to a system and method for channel time reservation in the medium access control functionality of wireless personal area networks, based on ultra wide band (UWB) systems for spatial reuse with links using transmit power control wherein a device in the network can provide information about the time slots in which other devices can reuse the same slots, which are already in use for communication. According to the invention the transmit power used to transmit all type of frames in the master link is less than the maximum power used to transmit beacon frames. In the system the devices of the slave link listen to the medium at the beginning of the reservation for a pre-defined duration to determine whether the slave device is within the interference range of the master link and the slave devices negotiate with each other for an adequate transmit power while reusing the data slots so as to ensure that the slave link does not interfere with the communication going on in the master link.
