Orthogonal frequency division multiplexing (OFDM) communication system and method to schedule transfers of first and second user communications

摘要

An Orthogonal Frequency Division Multiplexing (OFDM) communication system and method to schedule transfers of first and second user communications between the FDM communication system and a Wireless Communication Device (WCD) are provided. The OFDM communication system in one example includes an OFDM scheduling system to process Quality-of-Service Class Identifiers (QCIs) and determine if the first user communication having a first QCI can be scheduled subsequently and if the second user communication having a second QCI can be scheduled in place of the first user communication, and if the first user communication can be scheduled subsequently and the second user communication should be scheduled in place of the first user communication, then schedule the second user communication in place of the first user communication. An OFDM transceiver wirelessly transfers the second user communication in place of the first user communication between the OFDM communication system and the WCD based on scheduling.

1. An Orthogonal Frequency Division Multiplexing (OFDM) communication system to schedule transfers of first and second user communications between the OFDM communication system and a Wireless Communication Device (WCD), comprising:
an OFDM scheduling system configured to process Quality-of-Service Class Identifiers (QCIs) for the first and second user communications to determine if the first user communication having a first QCI can be scheduled subsequently and if the second user communication having a second QCI can be scheduled in place of the first user communication by re-allocating an OFDM Resource Block (RB) from the first user communication to the second user communication, and if the first user communication can be scheduled subsequently and if the second user communication should be scheduled in place of the first user communication, then schedule the second user communication in place of the first user communication; and an OFDM transceiver coupled to the OFDM scheduling system and configured to wirelessly transfer the second user communication in place of the first user communication between the OFDM communication system and the WCD based on the scheduling.
