Reverse link control to reduce forward link latency
First Claim
1. A method comprising:
- determining, at a mobile user equipment, an estimated impact on a wireless forward link packet to be received by the user equipment from an access point caused by a delay in sending at least one wireless reverse link packet to the access point, the estimated impact including at least one of an estimate of an amount of time that the wireless forward link will be idle as a result of the delay in sending the at least one wireless reverse link packet to the access point or an estimate of an amount of forward link traffic that will be generated in response to the at least one wireless reverse link packet, wherein the estimated impact is based on a size of the at least one wireless reverse link packet, a type of the at least one wireless reverse link packet, a nature of data included in the at least one wireless reverse link packet, or any combination thereof;
determining, at the user equipment, a priority for the at least one wireless reverse link packet for transmission from the user equipment to the access point when an indicator relating to the estimated impact breaches a corresponding threshold value;
refraining from assigning a priority to the at least one wireless reverse link packet when the indicator does not breach the corresponding threshold value,wherein the priority for the at least one wireless reverse link packet is based on at least the estimated impact on a forward link packet to be received by the user equipment from the access point caused by a delay in sending the at least one reverse link packet to the access point; and
transmitting the at least one reverse link packet from the UE to the access point based on at least the determined priority for the at least one reverse link packet.

Abstract
Some implementations provide a method for prioritizing reverse link packets so that particular reverse link packets are transmitted with a reduced latency in order to improve spectral efficiency of the forward link. The method also optionally includes weighting packets according to their determined lengths, and transmitting packets based on the determined weights. In one implementation, the method includes sorting packets at least according to one of size, type and nature of the data in the packets. Accordingly, sorting of the packets includes at least one of determining the size and the type of each packet. In one implementation, sorting the packets includes deep-packet inspection to determine a respective priority value for each packet.
