Profile-based packet rate adaptation for wireless systems

摘要

Bluetooth file transfers using FTP do not provide upper-layer reliability checking and rely on the Bluetooth device physical layer providing reliable data to upper layers of a Bluetooth stack. However, reliability checks implemented by the physical layer are typically not very robust and in some cases may fail to detect errors, thus may provide corrupted data to the upper layers for further processing and may result in data corruption/transfer failure. Non-FTP Bluetooth file transfers are typically more robust when it comes to reliability checking because of upper layer reliability checks. Functionality can be implemented to vary packet transmission parameters depending on a Bluetooth profile implemented on a communication link. A packet error rate of received packets can be compared against a different set of thresholds depending on whether the Bluetooth profile is an FTP profile. Appropriate values of packet transmission parameters can be selected based on the above comparison.

1. A method for communication comprising:
determining, by a first wireless network device, whether a wireless communication profile associated with a plurality of packets received from a second wireless network device is a first wireless communication profile, wherein the first wireless communication profile defines a first protocol used for communication of packets; determining a packet error rate associated with the plurality of packets; comparing the packet error rate with a first set of packet error rate thresholds defined for the first protocol and associated with the first wireless communication profile, if it is determined that the wireless communication profile is the first wireless communication profile; changing one or more packet transmission parameters associated with additional packets to be received based on the first protocol from the second wireless network device based at least in part on results of said comparing the packet error rate with the first set of packet error rate thresholds; comparing the packet error rate with a second set of packet error rate thresholds defined for a second protocol and associated with a second wireless communication profile used for communication of the packets, if it is determined that the wireless communication profile is not the first wireless communication profile; and changing the one or more packet transmission parameters associated with the additional packets to be received based on the second protocol from the second wireless network device based at least in part on results of said comparing the packet error rate with the second set of packet error rate thresholds, wherein the first set of packet error rate thresholds are associated with a first combination of a packet transmit rate and a first slot duration for the first wireless communication profile, wherein the second set of packet error rate thresholds are associated with a second combination of a second packet transmit rate and a second slot duration for the second wireless communication profile.
