Claim:
1. A method for scheduling low-delay transmissions from an access node, the method comprising: receiving, at at least one base band unit (BBU), a total packet delay calculated for each of one or more wireless devices served by a plurality of antennas connected to the at least one BBU via communication links, the total packet delay being a total delay between one or more data packets received at the wireless device; determining, at the BBU, delay associated with the communication links; assigning unique link identification numbers to each of the plurality of antennas and to each of the communication links connecting the plurality of antennas to the at least one BBU; storing the assigned unique link identification numbers in a look-up table at the BBU; associating, via the look-up table, subscriber identities reported by the one or more wireless devices to the unique link identification numbers; selecting a scheduling algorithm for at least one wireless device of the one or more wireless devices from one or more scheduling algorithms based on the association, wherein the at least one wireless device is served by the antenna connected to the BBU via the communication link having a highest-delay and lowest throughput of the communication links; and transmitting packet data for the at least one wireless device using the selected scheduling algorithm, wherein the calculated total packet delay and the associated subscriber identities are stored in a second look-up table at the BBU.
