Transmission mode determination method and device

Abstract

Embodiments of the present invention provide a method and device for determining a transmission mode, wherein the method includes: sending change information to a network side device, where the change information is used to indicate a desired transmission mode of a user equipment. In the embodiment of the present invention, the user equipment sends the change information requesting to change the transmission mode to the network side equipment, so that the network side equipment can determine the current transmission mode that the user equipment can execute based on the change information, so that the transmission mode of the user equipment can be accurately determined. The change not only reduces the unnecessary power consumption of the user equipment, achieves the effect of energy saving and power saving, but also ensures the data transmission performance of the system.

Description

technical field [0001] The present invention relates to the field of mobile communications, in particular to a method and device for determining a transmission mode Background technique [0002] At present, with the rapid development of mobile communication technology, the fifth-generation (fifth-generation, 5G) mobile communication system can adapt to more diverse scenarios and service requirements. Therefore, the application of the 5G system is becoming more and more extensive. Among them, in the 5G system, for different application scenarios, user equipment (UE) may support services with different numerical configurations. For example, UE supports both URLLC low-latency high-reliability services and large-capacity and high-speed eMBB business. [0003] For user equipment that supports multiple types of services, in order to ensure the data transmission performance of the system, in the 5G system, it is required that the user equipment must support the number of receiving...

Problems solved by technology

At this time, if the downlink scheduling of the network side equipment needs to use 4 antennas to receive downlink information, but the user equipment adopts 2 antennas to receive the downlink information and cannot meet the service QoS requirements, it will lead to a decrease in downlink system performance, for example, it will lead to an increase in the system block error rate BLER

[0005] It can be seen that in the 5G system, if the user equipment continues to maintain the transmission mode of 4-antenna reception or 2-antenna transmission, it will cause the user equipment to consume unnecessary power, which is not conducive to the user equipment to save power; Changes in the mode may lead to a decrease in the data transmission performance of the system
