If the bandwidth of the user equipment belongs to the 5G frequency band, the user equipment is shown to have the capability of adaptively changing the ratio of the uplink subframe and the downlink subframe, and the ratio of the uplink subframe and the downlink subframe is continuously adjusted.
Step 206, obtaining first service requirement information of the user equipment, determining a first dynamic ratio according to the first service requirement information, and setting a third uplink and downlink subframe ratio of the uplink and downlink subframes to be the first dynamic ratio.

In this embodiment, the first service requirement information includes a first uplink service requirement and a first downlink service requirement, and the first uplink/downlink service ratio is obtained by dividing the first uplink service requirement by the first downlink service requirement.
The first uplink service requirement refers to the number of uplink subframes required for transmitting the uplink service at a certain moment or time period; the first downlink traffic demand refers to the number of downlink subframes required for transmitting downlink traffic at a certain time or period.
In this embodiment, the first threshold is an uplink service main threshold, and the second threshold is a downlink service main threshold.

In this embodiment, step 207 specifically includes:
step 2071, obtaining a first channel environment, where the first channel environment includes interference information of multiple interfering cells, and determining an interference type according to the interference information.
In this embodiment, the interference type is determined according to the interference waveform characteristic corresponding to the interference index.
For example, the interference types are divided into co-channel interference, external interference, partial frequency band interference, and the like, and may be obtained primarily through interference measurement of resource blocks (RB for short).
Step 2072, determining whether the interference types of the multiple interfering cells are co-channel interference, if yes, executing step 2073; if not, go to step 2074.
Step 2073, obtaining downlink service state information and uplink service state information of multiple interfering cells, adjusting the symbols of the unconfigured subframes of the interfering cells with lower service load to be protection symbols according to the downlink service state information and the uplink service state information of the multiple interfering cells, calculating the number of the protection symbols, multiplying the number of the protection symbols by the interval of one symbol to obtain the first protection interval, and continuing to execute step 208.
For example, when the user equipment in two interfering cells with the same frequency interference performs a service, the service load in one interfering cell is larger, and the service load in the other interfering cell is smaller, the symbol of the non-configured subframe in the interfering cell with the smaller service load is adjusted to a protection symbol, so as to achieve the purpose of avoiding or reducing the interference.

In this embodiment, the ratio corresponding to the first service requirement information and the guard interval corresponding to the first channel environment may be preset or may not be preset.
For example, when most of the services processed by the ue are downlink services, more corresponding downlink subframes are configured, and the ratio at this time is not preset, but is configured according to the ratio configured when the ue performs the services.
Step 211, obtaining second service requirement information of the user equipment, determining a second dynamic ratio according to the second service requirement information, and setting a fourth uplink and downlink subframe ratio of the uplink and downlink subframes to the second dynamic ratio.
In this embodiment, step 211 specifically includes:
step 2111, calculating a second uplink/downlink service ratio according to the second service requirement information, and determining whether the second uplink/downlink service ratio is greater than a first threshold or less than a second threshold, the first threshold being greater than the second threshold, if it is determined that the second uplink/downlink service ratio is greater than the first threshold, executing step 2112; if the second uplink/downlink traffic ratio is smaller than the second threshold, execute step 2113; if the second uplink/downlink traffic ratio is greater than the second threshold and smaller than the first threshold, step 2114 is performed.

The second uplink service requirement refers to the number of uplink subframes required for transmitting the uplink service at a certain moment or time period; the downlink service requirement refers to the number of downlink subframes required for transmitting downlink service at a certain time or time period.

In this embodiment, step 212 specifically includes:
step 2121, obtaining a second channel environment, where the second channel environment includes interference information of multiple interfering cells, and determining an interference type according to the interference information.
In this embodiment, the interference type is determined according to the interference waveform characteristic corresponding to the interference index.
For example, the interference types are classified into co-channel interference, external interference, partial frequency band interference, and the like, and can be obtained preliminarily through interference measurement of the resource block.

For example, when the user equipment in two interfering cells with the same frequency interference performs a service, the service load in one interfering cell is larger, and the service load in the other interfering cell is smaller, the symbol of the non-configured subframe in the interfering cell with the smaller service load is adjusted to a protection symbol, so as to achieve the purpose of avoiding or reducing the interference.

In this embodiment, an uplink and downlink handover guard interval tgap (ns) is calculated according to a distance d from a base station to a ue, where tgap (ns) > d × 2/C, where d is a distance (m) from the ue to the base station, and C is a signal propagation speed m/s.
Acquiring next symbol duration Tsymble of a subcarrier interval, dividing uplink and downlink switching guard interval TGAP (ns) by the symbol duration Tsymble to obtain symbol number NumGp required by the uplink and downlink switching guard interval,
in this embodiment, the uplink and downlink switching guard interval tgap (ns) is an integer, as long as the minimum value of tgap (ns) > d × 2/C is satisfied, where the minimum value is a critical value of the time length of the symbol number of the interference timeslot, so that the interference timeslot can be avoided, and the utilization rate of the non-interference timeslot can be maximized.
Step 213, sending a UE-Specific DCI signaling to the UE, where the UE-Specific DCI signaling carries the fourth uplink/downlink subframe ratio.

In this embodiment, the UE-level uplink and downlink subframe ratio in the neighboring base station cell, and the service type and the UE location only need to have a change of one piece of information, which indicates that the UE switches from occupying the neighboring base station cell for service to the cell for service.
Step 215, judging whether the fourth uplink and downlink subframe ratio of the uplink and downlink subframes is consistent with the ratio of the ratio model of the adjacent base station cell, if so, ending the process; if not, go to step 216.
Step 216, judging whether the time of the dynamic adjustment timer of the base station resource pool is greater than the set time, if not, continuing to execute the step 216; if yes, go to step 217.
And step 217, adjusting the ratio of the fourth uplink subframe and the fourth downlink subframe of the uplink subframe and the downlink subframe to be consistent with the ratio of the ratio model.
In this embodiment, when the user equipment occupies the neighboring cell base station cell to perform service switching to the cell to perform service, if the uplink and downlink subframe ratio of the neighboring cell base station cell is not consistent with that of the cell, the uplink and downlink subframe ratio of the cell is adjusted to be consistent with that of the neighboring cell base station cell performing service.
Step 218, determining whether the ue enters an idle state; if yes, ending the process; if not, continue to step 206.
In this embodiment, when the ue enters the idle state, it indicates that the service performed by the ue is finished; and when the user equipment does not enter the idle state, indicating that the service performed by the user equipment is not finished, and continuously performing dynamic adjustment on the ratio of the uplink subframe and the downlink subframe.
