Problems solved by technology

[0003] However, for FDD (Frequency Division Duplex) systems in certain frequency bands, the distance between the uplink and downlink spectrum is relatively close. For the radio frequency system, the third-order intermodulation interference products generated by the downlink transmission signal will be coupled into the uplink receiver. Within the bandwidth, improve the noise floor of the receiver when receiving uplink, thus affecting the correct probability of uplink demodulation

Abstract

The invention provides a scheduling method, device and equipment, and relates to the technical field of communication. The method comprises the following steps: allocating or adjusting at least one of service scheduling bandwidths of one or more service transmissions of first user equipment, a starting frequency point position of service scheduling and a termination frequency point position of service scheduling, wherein at least one of the allocated or adjusted service scheduling bandwidth, the starting frequency point position of service scheduling and the ending frequency point position of service scheduling is located in a first frequency band, and the first frequency band has no intermodulation interference, or the intermodulation interference degree of the first frequency band is smaller than a preset threshold value; the service transmission refers to transmission of control signaling and / or service data, and the service transmission comprises uplink transmission and / or downlink transmission of the service. According to the scheme, the problem that intermodulation interference affects transmission in the prior art is solved.

Description

technical field [0001] The present invention relates to the field of communication technologies, in particular to a scheduling method, device and equipment. Background technique [0002] In the current scheduling scheme of the base station, the scheduling of the terminal is distinguished from the uplink and downlink services of the terminal, and the scheduling is carried out independently. Specifically, when the base station schedules users, it can determine the scheduling result of the uplink or downlink unidirectional link (such as modulation and coding scheme, frequency domain scheduling location, etc.) to maximize the system spectral efficiency. For example, when performing uplink service scheduling, the base station refers to the channel quality / SINR of the uplink; when performing downlink service scheduling, the base station refers to the channel quality / SINR of the downlink. [0003] However, for FDD (Frequency Division Duplex) systems in certain frequency bands, th...
