US Patent 10079659 Processing method and system for hybrid automatic repeat request data transmissions

In data transmissions, a processing method for hybrid automatic repeat request (HARQ) is applied to a transmitter transmitting a first semi-persistent scheduling (SPS) data packet to a receiver. The receiver receives the first SPS data packet and transmits feedback to the transmitter. The transmitter which receives the feedback message can determine that a transmission of a repeat SPS data packet is required when the feedback message is a negative acknowledgement, and a repeat SPS data packet together with a HARQ ID corresponding to the repeat SPS data packet is transmitted to the receiver. If the receiver can match the repeat SPS data packet with the first SPS data packet according to the HARQ ID, a combination of the first SPS data packet and the repeat SPS data packet can be decoded.
