Step 101：The transmission quality at least two communication modes that user equipment may be selected to use is assessed in base station,
To select at least one communication mode therein；
In one embodiment, base station includes eNB (base stations 4G) and gNB (base stations 5G), and UE is carried out in the present embodiment
When row transmission, using split SRB structures.Between base station wirelessly, the letter being connect each other with UE is assessed in two base stations
The parameters such as number intensity, transmission speed, transmission signaling reliability.In an application scenarios, specified in two base station eNBs and gNB
ENB is master base station, and master base station is according to assessment as a result, selecting one or two kinds of communication mode in LTE and NR as UL's
Communication mode.
Step 102：At least one communication mode that selection is sent to the user equipment, so that the use
Family equipment carries out uplink communication using the selected at least one communication mode；
Specifically, as master base station according to the result of selection instruction will occur for eNB to UE, such as select LTE as logical
Letter mode.In an application scenarios, selection instruction is carried in RRC information and transmits.Due to the consumption of RRC information transmission
Greatly, it therefore can't continually transmit, and the selection of communication mode is the connection communication based on two base stations and UE instantly
What quality determined, there is timeliness, then just need to be defined the effective time of this message.Therefore, RCC message in addition to
Selection instruction is carried, the effective time of this communication mode is also selected.General UE is built-in with time set, and UE is being received
To after the RCC message for the instruction for carrying selection communication mode, effective time therein is read, what is carried using RCC message
While selection instruction, start built-in clocking capability, is limited with the effective time read and starts countdown, in timing time
