摘要： Embodiments described herein provides a system for detecting data received in a low power low rate (LPLR) data frame format. The system includes a receiver and control circuitry. The receiver is configured to receive a data frame comprising an LPLR preamble portion and an LPLR data portion following the LPLR preamble portion. The LPLR preamble portion and the LPLR data portion occupy a bandwidth that is less than an allowed bandwidth. The control circuitry is configured to determine a mode of the data frame based on whether the data frame has an additional portion, and detect a data field in the LPLR preamble portion from the data frame based on the mode of the data frame.

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.
