Description
Technical Field
The present invention relates to the field of wireless communications, and in particular, to a TDMA-based channel resource allocation method and apparatus in a MESH network, and a readable storage medium.
Background
In the MESH of the mobile ad hoc network, with the solution of the Time slot synchronization problem, the LTE-based TDMA (Time Division Multiple Access) scheme is widely adopted, different TDMA protocols have different frame structure designs, and different Time slot scheduling modes are adopted, but no matter which scheduling mode is adopted, only one node transmits at each Time in one MESH subnet, and other nodes are in a receiving state, and under the condition, the resource utilization rate and the spectrum efficiency are not high.
In order to improve the resource utilization rate and the spectrum efficiency of the network, a time slot multiplexing scheme (two hops or nodes meeting a certain condition can multiplex the same time slot) can be adopted, but in the wireless MESH network, the same time slot is adopted among the multiplexing nodes, so that more or less interference is inevitably introduced, and the system capacity is reduced.
For example, in the existing TDMA scheme shown in fig. 1, each node allocates a fixed time slot, only a plurality of nodes transmit data at each time in the MESH subnet, and each node accesses the MESH subnet in a time division multiple access manner. In addition, the master node allocates the dynamic region resource RF1 to each slave node according to a certain policy, as shown in fig. 1, the Time slots T10 to T12 are allocated to the node N0, and the Time slots T13 to T15 are allocated to the node N3, at this Time, if it is detected that the node N0 and the node N3 can multiplex the same TTI (Transmission Time Interval), the node N0 and the node N3 can multiplex the same dynamic region Time slot. In the MESH subnet, if the nodes (e.g., node N0 and node N3) of the multiplexing time slot transmit data at the same time, there may be interference between the nodes of the multiplexing time slot, which results in a smaller system capacity and is not favorable for improving the competitiveness of the MESH product.
