Abstract: A method of communication scheduling in a multihop network is provided. The multihop network comprises a base station and at least one relay station. The method includes allocating a downlink relay to a relay station; assigning a first one or more connection identifiers to be locally scheduled at the relay station for communication on a first portion of the downlink relay; and assigning a second one or more connection identifiers to be centrally scheduled by the base station for communication on a second portion of the downlink relay.

Abstract: A system and method to facilitate path selection in a multihop network includes receiving by a base station a path metric associated with each of a plurality of stations neighboring to a subscriber station; comparing each of the path metrics with a current path metric; and transmitting a path selection recommendation from the base station to the subscriber station when one of the compared path metrics is better than the current path metric.

Abstract: Techniques are provided for improving broadcast efficiency in a multihop network having a base station which transmits a downlink signal, at least one relay station and at least one node associated with the relay station. The relay station relays or retransmits the downlink signal it receives from the base station to nodes associated with the relay station. The base station monitors downlink transmission metrics provided by each of the nodes associated with the relay station. Each downlink transmission metric provides a measure of the downlink signal received by a particular node from the base station. Based on the downlink transmission metrics, the base station can decide if the relay station should continue to relay or retransmit the downlink signal to the nodes associated with the relay station.
