A handover-based MCS processing method disclosed in the embodiment of the present application is introduced. Referring to FIG. 1, the method may include:

Step S11: After the terminal accesses the source base station, the source base station receives the downlink measurement quantity of the terminal.

After the terminal accesses the source base station, the source base station configures the measurement configuration file required for the terminal to switch to the target base station. Correspondingly, the terminal performs related measurements according to the measurement configuration file, obtains the downlink measurement quantity, and reports the downlink measurement quantity.

In this embodiment, the downlink measurement quantity may include, but is not limited to, CQI (Channel Quality Indicator), and RSRP (Reference Signal Received Power).

Step S12: The source base station measures an uplink measurement quantity of the terminal.

After the terminal accesses the source base station, the source base station also needs to measure the uplink measurement quantity of the terminal.

The uplink measurement may include, but is not limited to, an uplink SINR (Signal to Interference plus Noise Ratio) and interference.

Step S13: The source base station maps, according to the uplink measurement quantity, an uplink measurement quantity after the terminal switches to the target base station, as a reference uplink measurement quantity, and according to the downlink measurement quantity, maps the terminal to switch to The downlink measurement quantity after the target base station is used as a reference downlink measurement quantity.

The source base station maps, according to the uplink measurement quantity, the uplink measurement quantity after the terminal switches to the target base station, as the reference uplink measurement quantity, and specifically includes: the source base station searches for the presence of the uplink measurement quantity mapping table. The uplink measurement quantity matched with the uplink measurement quantity and the target base station, if present, is used to find the matched uplink measurement quantity as the reference uplink measurement quantity after the terminal switches to the target base station.

It should be noted that the uplink measurement quantity mapping table may include multiple different mapping relationships, and the mapping relationship may be understood as: a mapping relationship between the uplink measurement quantity of the source base station and the uplink measurement quantity after the terminal switches to the target base station.

The uplink measurement amount mapping table can be obtained in advance by testing or simulation.

Similarly, the source base station, according to the downlink measurement quantity, mapping the downlink measurement quantity after the terminal switches to the target base station, as the reference downlink measurement quantity, may specifically include: the source base station mapping in the downlink measurement quantity The table finds whether there is a downlink measurement quantity that matches the downlink measurement quantity and the target base station, and if so, finds the matched downlink measurement quantity as the reference downlink measurement quantity after the terminal switches to the target base station.

It should be noted that the downlink measurement quantity mapping table may include multiple different mapping relationships, and the mapping relationship may be understood as: a mapping relationship between the downlink measurement quantity of the source base station and the downlink measurement quantity after the terminal switches to the target base station.

The downlink measurement amount mapping table can be obtained in advance by testing or simulation.

Step S14: The source base station sends the reference uplink measurement quantity and the reference downlink measurement quantity to the target base station, so that the target base station, before the terminal switches to the target base station, according to the reference And determining, by the uplink measurement quantity and the reference downlink measurement quantity, a reference MCS, and using the reference MCS after the terminal switches to the target base station.

The reference MCS is an initial MCS used after the terminal switches to the target base station.

Since the target base station determines the reference modulation and coding scheme MCS according to the reference uplink measurement quantity and the reference downlink measurement quantity before the terminal switches to the target base station, the target base station does not acquire the downlink measurement quantity of the terminal. At this time, the target base station can still determine the MCS suitable for the channel quality condition, thereby reducing signaling and service delay, and reducing the packet loss rate. The process of determining the reference MCS by the target base station according to the reference uplink measurement quantity and the reference downlink measurement quantity, and the process of determining the MCS according to the uplink measurement quantity and the downlink measurement quantity in the prior art, and details are not described herein again.

After the terminal is switched to the target base station, using the reference MCS can be understood as: after the terminal switches to the target base station, the target base station does not receive the actual downlink measurement quantity and uplink measurement quantity of the terminal. The reference MCS is used.

It should be noted that, after the terminal is switched to the target base station, if the target base station can receive the actual downlink measurement quantity of the terminal, the target base station can determine the downlink MCS according to the actual downlink measurement quantity, and according to the uplink measurement quantity measured by the target base station, If the upstream MCS is determined, the reference MCS can no longer be used.

In the present application, the source base station may send the reference uplink measurement quantity and the reference downlink measurement quantity to the target base station, and the target base station determines the reference MCS before the terminal switches to the target base station, so the target base station may determine the reference MCS in advance, and switch at the terminal. After the target base station is used, the predetermined reference MCS is used in time to avoid the problem that the MCS cannot be determined in time, thereby reducing the packet loss rate of the data transmission and increasing the data transmission rate.

In another embodiment of the present application, another handover-based MCS processing method is introduced. Referring to FIG. 2, the method may include:

Step S21: After the terminal accesses the source base station, the source base station receives the downlink measurement quantity of the terminal.

Step S22: The source base station measures an uplink measurement quantity of the terminal.

Step S23: The source base station maps, according to the uplink measurement quantity, an uplink measurement quantity after the terminal switches to the target base station, as a reference uplink measurement quantity, and according to the downlink measurement quantity, maps the terminal to switch to The downlink measurement quantity after the target base station is used as a reference downlink measurement quantity.

The steps S21-S23 are the same as the steps S11-S13 introduced in the foregoing embodiment. For the detailed process of the steps S21-S23, refer to the related description of the steps S11-S13, and details are not described herein again.

Step S24: The source base station maps the reference MCS according to the reference uplink measurement quantity and the reference downlink measurement quantity, and sends the reference MCS to the target base station, so that the target base station is in the Before the terminal switches to the target base station, the reference MCS is received, and after the terminal switches to the target base station, the reference MCS is used.

In this embodiment, the source base station maps the reference MCS according to the reference uplink measurement quantity and the reference downlink measurement quantity, and sends the reference MCS to the target base station, where the target base station only needs to receive the reference MCS. .

After the terminal is switched to the target base station, the reference MCS can be understood as: after the target base station switches to the target base station, after the terminal does not receive the actual downlink measurement quantity and uplink measurement quantity of the terminal, Use the reference MCS.

In the present application, the source base station may map the reference MCS according to the reference uplink measurement quantity and the reference downlink measurement quantity, and send the reference MCS to the target base station, and the target base station receives the reference MCS before the terminal switches to the target base station, so the target The base station can determine the reference MCS in advance, and use the predetermined reference MCS in time after the terminal switches to the target base station, so as to avoid the problem that the MCS cannot be determined in time, thereby reducing the packet loss rate of the data transmission and increasing the data transmission rate.

In this embodiment, steps S21-S24 are described by way of example, for example:

After the terminal accesses the source base station, the source base station configures the conditions required for the handover of the terminal, including the neighboring base station (which can be understood as: the target base station) and the RSRP or RSRQ (Reference Signal Receiving Quality) threshold of the source base station, The triggering time and the number of triggers. For example, when the RSRP of the neighboring base station is set to be greater than the source base station by 3 dB and the triggering time is 640 ms, the handover procedure can be performed for the terminal.

When the UE (User Equipment) terminal reports the handover-based measurement report, it means that the conditions required for the handover are met, that is, the RSRP of the neighboring base station measured by the UE terminal is greater than the original base station by 3 dB, and the duration is greater than Equal to 640ms.

In this case, the source base station may obtain the target according to the RSRP difference between the neighboring base station and the source base station, the uplink MCS of the terminal UE of the access source base station, and the downlink MCS, according to the RSRP difference obtained by the simulation or the test, and the uplink MCS mapping of the source base station UE. The uplink MCS of the base station. Or, the downlink MCS and the uplink MCS of the target base station are respectively mapped according to the measured RSRP difference, the downlink MCS and the uplink MCS of the current base station (source base station), and are used as the reference downlink MCS and the reference uplink MCS, respectively.

The mapping process can find whether there is matching corresponding data in the mapping table. The mapping table can be obtained by simulation or testing in advance according to the channel type and measurement configuration. For example, as shown in Table 1, the RSRP-source base station RSRP difference of the target base station is greater than or equal to 3 dB, and the channel environment of the source base station is AWGN (Additive White Gaussian Noise), if the uplink MCS of the source base station is 5, the uplink MCS of the neighboring station is 7 and the downlink MCS is 7. If the switching configuration condition is that the RSRP of the target station minus the RSRP of the source base station is another value, or the channel environment served by the base station is other channels other than AWGN (Additive White Gaussian Noise), the mapping table also needs to be performed. Modify accordingly.

Table 1

Then, the source base station may send the handover request of the terminal, the reference uplink MCS of the terminal, and the reference downlink MCS to the target base station. After the handover is completed, the target base station provides the terminal with the MCS of the tracking channel according to the reference uplink MCS and the reference downlink MCS from the source base station. Therefore, even if the target base station cannot acquire the downlink measurement quantity (such as channel quality information) of the terminal in time, the terminal can be adapted to the channel condition to the greatest extent.

The target base station provides the MCS of the tracking channel for the terminal according to the reference uplink MCS and the reference downlink MCS from the source base station. It can be understood that the target base station directly uses the reference uplink MCS and the reference downlink MCS from the source base station as the MCS of the target base station tracking channel. Or, the target base station processes the reference uplink MCS and the reference downlink MCS from the source base station, and uses the processed MCS as the MCS of the target base station tracking channel.

The uplink MCS matching the uplink MCS and the reference uplink measurement quantity, if present, uses the found uplink MCS as the reference uplink MCS.

It should be noted that the uplink MCS mapping table may be obtained by testing or simulation in advance.

Step S34: The source base station maps the reference downlink MCS according to the downlink MCS and the reference downlink measurement quantity.

The downlink MCS matching the downlink MCS and the reference downlink measurement quantity, if present, uses the found downlink MCS as the reference downlink MCS.

It should be noted that the downlink MCS mapping table may be obtained by testing or simulation in advance.
