Abstract
Systems, methods, and software for hybrid automatic repeat request (HARQ) block error rate (BLER) control in wireless communications are provided herein. A wireless access system receives a media packet. The wireless access system also determines a first time difference between an allowable end-to-end delay for the media packet and a first consumed end-to-end delay for the media packet. The wireless access system also processes the first time difference to select a first HARQ BLER and transfers the media packet from the wireless access system using the first HARQ BLER.

A method of operating a wireless access system for hybrid automatic repeat request (HARQ) block error rate (BLER) control in wireless communications comprising:
- receiving a media packet;
- determining a first time difference between an allowable end-to-end delay for the media packet and a first consumed end-to-end delay for the media packet;
- processing the first time difference to select a first HARQ BLER;
- transferring the media packet from the wireless access system using the first HARQ BLER;
- identifying a HARQ negative acknowledgement (NACK) for the media packet;
- in response to the NACK for the media packet, determining a second time difference between the allowable end-to-end delay for the media packet and a second consumed end-to-end delay for the media packet;
- processing the second time difference to select a second HARQ BLER;
- and
- initiating a transfer process for the media packet based on the second HARQ BLER.
A wireless access system for hybrid automatic repeat request (HARQ) block error rate (BLER) control in wireless communications, the wireless access system comprising:
- a network receiver configured to receive a media packet;
- a BLER control system configured to determine a first time difference between an allowable end-to-end delay for the media packet and a first consumed end-to-end delay for the media packet;
- the BLER control system configured to process the first time difference to select a first HARQ BLER;
- a HARQ transceiver configured to transfer the media packet from the wireless access system using the first HARQ BLER;
- the BLER control system configured to identify a HARQ negative acknowledgement (NACK) for the media packet;
- the BLER control system configured to determine a second time difference between the allowable end-to-end delay for the media packet and a second consumed end-to-end delay for the media packet;
- the BLER control system configured to process the second time difference to select a second HARQ BLER;
- and
- the HARQ transceiver configured to initiate a transfer process of the media packet based on the second HARQ BLER.
