Description
Technical Field
The present invention relates to the field of communications technologies, and in particular, to a terminal scheduling method, a network device, and a terminal device.
Background
In 5G, the dependent deployment method requires dual connectivity using the LTE network and the NR network, and is one of important scenarios for initial deployment of 5 GNR. In the operation of NSA (non access stratum), a terminal is required to maintain dual-frequency dual transmission in uplink, that is, maintain dual transmission in uplink in an LTE frequency band and an NR frequency band. However, due to factors such as nonlinearity of radio frequency devices and the like, dual-transmission in uplink of a terminal on two frequency bands can bring intermodulation interference, the intermodulation interference is formed by combining and superposing a plurality of components at a transmitting end, for example, second-order intermodulation is f2-f1, third-order intermodulation is 2f2-f1 and 2f1-f2, and when the generated intermodulation interference falls into the frequency band received by the terminal, self-interference can be generated, so that the sensitivity of a receiver of the terminal is reduced.
When the terminal is in dual-transmission with intermodulation self-interference on two frequency bands, the sensitivity of the terminal receiver is reduced.
In the prior art, when the terminal generates self-interference due to double frequency and double emission, the simplest solution is to make the terminal fall back to a single emission mode to avoid the interference.
However, in a 5G non-independent deployment scenario, both LTE and NR need to transmit uplink, and the interference of second-order intermodulation specified in the current standard will cause sensitivity to drop by more than 20dB, which will have a serious impact on network coverage and downlink rate if not optimized.
