Power usage-aware spectral resource allocation in a satellite long term evolution (LTE) communication system

摘要

A method for resource allocation in a multi-beam satellite LTE network includes determining, via a communication processor, a per sub-frame resource block (RB) threshold value on a per-beam and per-LTE carrier basis, based on a total transmission power and shared power amplifiers available to multiple beams of a space vehicle while ensuring that power amplifiers operate in a linear amplification region. The method further includes communicating the LTE per subframe RB threshold value to a downlink LTE scheduler function within the eNode-B to ensure that the count of subframe level RB allocations is less than the determined LTE per subframe RB threshold value.
