Selective protection based on sequence numbers in coexisting networks

摘要

A wireless device comprises a first wireless transceiver, a second wireless transceiver, and control logic. The control logic is coupled to the first wireless transceiver and the second wireless transceiver. The control logic is configured to determine whether to transmit protection frames (e.g., clear-to-send 2 self frames) based upon sequence numbers in frames received from another device.

1. A combo wireless device, comprising:
a first wireless transceiver configured to send and receive wireless communications in accordance with a first wireless protocol; a second wireless transceiver configured to send and receive wireless communications in accordance with a second wireless protocol, said second wireless protocol coexisting with said first wireless protocol; a control logic coupled to and coordinates the operation of said first and second wireless transceivers,
wherein said control logic determines whether to transmit clear-to-send 2 self (C2S) frames based upon media access control (MAC) sequence numbers in frames received from another device, the control logic dynamically enables and disables transmission of C2S frames,clears an enable flag and coordinates beginning transmitting clear-to-send 2 self (C2S) frames upon determining that more than a threshold period of time has elapsed without detecting any missing MAC sequence numbers in wireless frames or upon determining that more than a threshold number of wireless frames have been received without a missing MAC sequence number.
