Abstract: A method of allocating time for a communication device includes receiving a request for allocation of a second time period related to a second communication link, after allocating a first time period related to a first communication link, and reserving the portion of the second period overlapping the first period, wherein the first link is generated between first and second communication devices, and the second link is generated between third and fourth communication devices. A further aspect of the method includes identifying the first period reserved in advance, and receiving the request for allocating the second period, and allocating the second period to spatially overlap the first time period. A further aspect of the method includes identifying an existing reservation for the first period of the first link, receiving a new reservation for the second period, and allocating the second period to spatially overlap the first period.
