BROADCAST EFFICIENCY IN A MULTIHOP NETWORK
First Claim
1. In a multihop network comprising a base station which transmits a first downlink signal, at least one relay station and at least one node associated with the relay station, a method comprising:
- retransmitting the first downlink signal from the relay station to nodes associated with the relay station;
monitoring, at the base station, one or more downlink transmission metrics provided by each of the nodes associated with the relay station, wherein each downlink transmission metric provides a measure of the first downlink signal received by a particular node from the base station; and
deciding, at the base station based on the downlink transmission metrics provided by the nodes associated with the relay station, if the relay station is to continue retransmitting the first downlink signal to the nodes associated with the relay station.

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.

18. In a multihop network comprising a base station which transmits a first downlink signal, at least one relay station which transmits a second downlink signal which originates at the at least one relay station, and at least one node associated with the relay station, a method comprising:
-
transmitting the second downlink signal and retransmitting the first downlink signal from the relay station to nodes associated with the relay station; monitoring, at the base station, one or more downlink transmission metrics provided by each of the nodes associated with the relay station, wherein each downlink transmission metric provides a measure of the first downlink signal received by a particular node from the base station; and deciding, at the base station based on the downlink transmission metrics provided by the nodes associated with the relay station, if the relay station is to continue transmitting the second downlink signal and retransmitting the first downlink signal to the nodes associated with the relay station. - View Dependent Claims (19)
