Cross-layer scheduling based on lower layer feedback

摘要

Systems, methods, apparatus, and techniques are provided for retransmitting packets of data. A Radio Link Control (RLC) layer data packet is generated, and the RLC layer data packet is converted to one or more physical (PHY) layer data packets. The one or more PHY layer data packets are transmitted. At least one of a hybrid automatic transmission request (HARQ) acknowledgement (ACK) message and a HARQ negative acknowledgment (NACK) message is received from a receiver in response to transmission of the one or more PHY layer data packets. It is determined whether the at least one of the HARQ ACK message and the HARQ NACK message represents a automatic transmission request (ARQ) ACK message or a ARQ NACK message.

1. A system for retransmitting packets of data, the system comprising:
processing circuitry configured to generate a Radio Link Control (RLC) layer data packet;
transmission circuitry configured to
convert the RLC layer data packet to one or more physical (PHY) layer data packets, andtransmit the one or more PHY layer data packets, andpermanently disable transmission of RLC polling status messages; and scheduling circuitry configured to
receive at least one of a hybrid automatic transmission request (HARQ) acknowledgement (ACK) message and a HARQ negative acknowledgment (NACK) message from a receiver in response to transmission of the one or more PHY layer data packets, anddetermine whether the at least one of the HARQ ACK message and the HARQ NACK message represents a automatic transmission request (ARQ) ACK message or a ARQ NACK message.
