Abstract:
1. An apparatus, comprising: a transmitter configured to transmit data through relays to network elements, wherein downlink and uplink transmission resources are allocated from the apparatus to the relays and the network elements; a point-to-point detector configured to detect a failure in a point-to-point data transmission from the apparatus to a relay; a scheduler configured to reschedule data transmission and reallocate the downlink and uplink transmission resources according to the point-to-point data transmission that failed; a point-to-multipoint detector configured to detect a failure in a point-to-multipoint data transmission between the relay and a network element; and a controller configured to determine a particular link that failed between the relay and the network element, wherein the scheduler is further configured to reschedule data transmission and reallocate the downlink and uplink transmission resources according to the point-to-multipoint transmission for the particular link that failed.
