The sensing detection index and the transmission mode conversion parameter corresponding to the traffic flow may be obtained by various existing methods.
In one embodiment, different mode switching parameter thresholds (transmission mode switching thresholds) corresponding to the sensing result are set for different services in advance. When a user uses a plurality of services at the same time, the service flow of each service may switch the transmission mode according to the respective mode switching parameter threshold. For different services, the mode switching parameter threshold may be adjusted according to respective service indicators.
And 104, acquiring a plurality of antenna transmission modes corresponding to the plurality of service flows, and performing data processing on the plurality of service flows based on the plurality of antenna transmission modes, so that each service flow can perform data transmission in the corresponding antenna transmission mode.
The data processing comprises the following steps: data merging, segmenting, multiplexing and the like, a plurality of service flows can be subjected to data processing based on a plurality of antenna transmission modes by adopting various existing methods, so that each service flow can carry out data transmission in the corresponding antenna transmission mode. The number of antennas may be 4, 8, 16, etc., and the antenna transmission mode may include: the spatial multiplexing mode, the transmit diversity mode, and the like are spatial multiplexing modes, transmit diversity modes, and the like in the existing MIMO antenna technology. For example, the first service may use a space division multiplexing mode, and the second service may use a transmit diversity mode, thereby implementing differentiated quality control.
The data transmission method for the concurrent service according to the above embodiment provides an MIMO adaptive transmission mechanism applied to the concurrent service of the mobile network, and may be applied to a mobile network multi-antenna system (LTE/5G NR, etc.), and when multiple services are concurrent, different transmission mechanisms are provided for different services.
In one embodiment, the perception result includes: a first quality level and a second quality level.

For example, the first quality level is good and the second quality level is bad. When the result of the first service is "excellent", a transmission switching threshold (a first parameter threshold) threshold 1 is set, and when the result of the first service is "poor", a transmission switching threshold (a second parameter threshold) threshold db1 is set.
And judging whether the sensing detection index is smaller than a detection index threshold value, if so, determining that the sensing result of the service flow is a first quality grade, and if not, determining that the sensing result of the service flow is a second quality grade.

Threshold 1, the service is switched to a transmit diversity mode, and the two antennas transmit the same data to ensure the transmission quality; and at this moment, the service II still keeps the original space division multiplexing mode, and the rate gain of multi-antenna transmission is obtained.
After a period of time, if the sensing result of the second service is "excellent" and the SINR of the second service is less than the first parameter threshold corresponding to the sensing result of "excellent", the second service is converted into a transmit diversity mode, and the two antennas transmit the same data, thereby ensuring that the transmission quality is also converted into a transmit diversity mode. At this time, the two services use the same multi-antenna transmission mode.

the mode determining module is configured to determine, if the sensing result is the first quality level, an antenna transmission mode of the service flow according to a comparison result between the transmission mode conversion parameter and the first parameter threshold; and if the sensing result is the second quality grade, determining the antenna transmission mode of the service stream according to the comparison result of the transmission mode conversion parameter and the second parameter threshold.
14. The apparatus of claim 13, the transmission mode transition parameters comprising: SINR;
the mode determining module is configured to determine whether the transmission mode switching parameter is smaller than the first parameter threshold, if so, adjust the antenna transmission mode of the service flow to be a second transmission mode, and if not, keep the antenna transmission mode of the service flow to be a first transmission mode; wherein the first transmission mode comprises: a space division multiplexing mode; the second transmission mode includes: transmit diversity mode.
15. The apparatus of claim 14, wherein,
the mode determining module is further configured to determine whether the transmission mode switching parameter is smaller than the second parameter threshold, if so, adjust the antenna transmission mode of the service flow to be the second transmission mode, and if not, keep the antenna transmission mode of the service flow to be the first transmission mode.
16. The apparatus of claim 9, wherein,
the data processing comprises: data merging, segmentation and multiplexing.
17. A data transmission apparatus for concurrent services, comprising:
a memory; and a processor coupled to the memory, the processor configured to perform the method of any of claims 1-8 based on instructions stored in the memory.
18. A base station, comprising:
a data transmission arrangement for concurrent services according to any one of claims 9 to 17.
19. A computer-readable storage medium having stored thereon computer instructions for execution by a processor of the method of any one of claims 1 to 8.
