Abstract
Medium reservation modifications can be requested and granted wherein a master device allocates a medium using reservations that are observed by other devices sharing the medium and a slave device complies with reservations by holding data for transmission until its reservation in time arrives by determining a reserved length of an upcoming transmitting opportunity reserved for a slave device, determining, at the slave device, a desired length for transmitting data from the slave device over the medium, comparing the reserved length and the desired length to determine if a medium reservation modification is warranted, if the medium reservation modification is warranted, requesting, using the slave device and the medium, during the reserved time covered by the medium reservation, the medium reservation modification, and determining, at the master device, whether to grant or deny the medium reservation modification and conveying the determination to the slave device.
