The invention provides a wireless communication method. The method comprises the following steps: receiving, by a cluster header, a request frame sent by each cluster node to perform data transmissionwith the cluster head, wherein the request frame carries length information of to-be-transmitted data packets; sorting all to-be-transmitted data packets according to the priorities of the to-be-transmitted data packets, wherein the priorities corresponding to the to-be-transmitted data packets with shorter packet lengths are higher; allocating the to-be-transmitted data packets to first time slots of at least two channels in sequence according to the priorities from high to low; and if the first time slots of all channels are allocated and there are remaining to-be-transmitted data packets,allocating the remaining to-be-transmitted data packets to next time slots of at least two channels in sequence according to the priorities from high to low. The invention further provides a wirelesscommunication apparatus, a communication apparatus, and a readable storage medium. By adoption of the wireless communication method, the utilization of the channels is improved, and the real-time performance and throughput of the network are improved.
