Methods for allocating and scheduling uplink and downlink transmissions and apparatuses thereof

摘要

At least one example embodiment discloses a method for allocating downlink transmissions to a plurality of user equipments (UEs) from a base station. The method includes allocating downlink transmission air-time of the base station to a plurality of groups, associating each of the plurality of UEs to the plurality of groups, a throughput of each associated UE in a same group being affected by the remaining UEs in the same group and determining a resource sharing mode associated with each of the plurality of groups, the resource sharing mode being one of a first mode and a second mode, the base station allocating the same throughput to each associated UE in the associated group in the first mode and the base station allocating the same transmission time to each associated UE in the associated group in the second mode.

1. A method for allocating downlink transmissions to a plurality of user equipments (UEs) from a base station, the method comprising:
allocating downlink transmission air-time of the base station to a plurality of groups; associating each of the plurality of UEs to the plurality of groups, a throughput of each associated UE in a same group being affected by remaining UEs in the same group; determining a resource sharing mode associated with each of the plurality of groups, the resource sharing mode being one of a first mode and a second mode, the base station allocating a same throughput to each associated UE in the same associated group in the first mode and the base station allocating a same transmission time to each associated UE in the same associated group in the second mode; determining downlink transmission slices associated with the plurality of groups, each of the downlink transmission slices being associated with a queue, wherein the determining the downlink transmission slices includes determining weights for the queues, respectively, and each weight indicates a percentage of total downlink transmission air-time for the same associated group; and for each queue, determining a token to be removed from a bucket associated with the queue, the token being based on a cumulative frame transmission time for a previously transmitted frame, each bucket having a size.
