Multiple input multiple output (MIMO) can greatly improve the throughput and frequency utilization of wireless transmission systems. In the IEEE 802.11ax protocol, 4G, 5G, and even future 6G communications, MIMO has greatly increased the throughput of transmissions. Proper channel bonding strategies can improve channel utilization and transmission throughput. This paper proposes an outage probability based channel bonding algorithm (OP-CB). OP-CB calculates the outage probability according to the average signal-to-noise ratio (SNR) and the threshold signal-to-noise ratio. SNR is affected by transmission power and transmission distance. And then OP-CB performs channel bonding according to the outage of data transmission. The algorithm proposed in this paper can be used in massive MIMO (mMIMO) in 5G and future 6G communications. Combing the outage probability with the channel bonding technique can improve the success rate of data transmissions. The simulation results show that OP-CB can improve the throughput of data transmission by about 40% when the transmission power is low or the transmission distance is large. OP-BC can also reduce the bit error rate (BER).
