Problems solved by technology

[0005] However, in the 5G non-independent deployment scenario, both LTE and NR need to transmit uplink. The interference of second-order intermodulation stipulated in the current standard will cause the sensitivity to drop by more than 20dB. If it is not optimized, it will have a serious impact on network coverage and downlink rate.

Embodiment Construction

[0068] Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the invention may be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided for more thorough understanding of the present invention and to fully convey the scope of the present invention to those skilled in the art.

[0069] The embodiments of the present invention aim at the prior art, when the frequency band combination or channel combination with severe interference, the network adopts the time-division scheduling method, allowing the UE to transmit time-division uplink in the LTE and NR frequency bands, and only perform uplink on one frequency band at the same time sent to avoid interference.

Abstract

Embodiments of the present invention provide a terminal scheduling method, a network device and a terminal device, the scheduling method comprising: sending scheduling information to a terminal, the scheduling information being used for enabling the terminal to transmit data in a time division manner between at least two frequency bands in which interference occurs. According to the scheme of theinvention, uplink transmission is carried out on two frequency bands in a time division manner, so that the problem of terminal self-interference is avoided.

Description

technical field [0001] The present invention relates to the field of communication technologies, and in particular to a terminal scheduling method, network equipment and terminal equipment. Background technique [0002] In 5G, the non-standalone deployment method needs to use LTE network and NR network for dual connection, which is one of the important scenarios for the initial deployment of 5G NR. In the operation of NSA (Non-Access Stratum), the terminal is required to maintain dual frequency and dual transmission in the uplink, that is, to maintain dual uplink transmission in the LTE frequency band and the NR frequency band. However, due to non-linear factors such as radio frequency devices, intermodulation interference will be caused by the dual transmission of the terminal uplink on the two frequency bands. The intermodulation interference is formed by the combination and superposition of multiple components at the transmitting end. For example, the second-order intermo...
