Abstract
A transmitting data unit (101) transmits a data message (110) comprising a plurality of data blocks (111-112) to at least one receiving data unit (102-103). Upon reception of the data blocks, at least one corruption metric is determined for the received data blocks. Using the at least one corruption metric, it is determined if a portion of received data blocks has been inadequately received. When the portion of received data blocks has been inadequately received, a resend counter is incremented. If the resend counter exceeds a counter limit value, transmission of resend requests is disabled. Transmission of resend requests may be re-enabled upon satisfaction of a re-enable condition or expiration of a predetermined period of time.
