Technical Field

The present application relates to the field of communications, and in particular, to a scheduling method, apparatus, and computer readable storage medium.

Background

In the existing communication system, the uplink and downlink time slot ratio of the base station is usually 3:7, and in a scene with a large uploading requirement of the terminal, for example, in an industrial internet scene, the existing uplink and downlink time slot ratio can cause insufficient uplink resources of service data.

One existing scheme is to increase uplink resources of service data by increasing uplink time slot ratio, for example, the uplink time slot ratio and the downlink time slot ratio are configured to be 4:6 or 5:5. However, communication interference may occur between two adjacent base stations of different uplink and downlink timeslots.

Disclosure of Invention

The application provides a scheduling method, a scheduling device and a computer readable storage medium, which can improve uplink resources of service data and reduce communication interference between base stations.

In order to achieve the above purpose, the present application adopts the following technical scheme:

in a first aspect, a scheduling method is provided, the method including: acquiring a parameter value set of parameters when the network environment of the terminal in the first time period is in an environment stable state; the parameter is used for representing the channel quality of an uplink service channel of the terminal, and the parameter value set comprises parameter values of the parameter at a plurality of moments in a second time period, wherein the second time period is a time period after the first time period; determining whether the channel quality of the uplink traffic channel is in a quality stable state according to the parameter value set; transmitting a scheduling message under the condition that the channel quality of an uplink traffic channel is not in a quality stable state; the scheduling information is used for indicating the terminal to report the detection information of the uplink service channel.

Based on the scheme, when the network environment of the terminal is in an environment stable state in a first time period, the channel quality of an uplink traffic channel of the terminal is determined not to be in a quality stable state by acquiring and according to a parameter value set of the parameters, and then a scheduling message for indicating the terminal to report the detection information of the uplink traffic channel is sent to the terminal. Under the general condition, the terminal usually receives the scheduling information periodically and reports the detection information of the uplink traffic channel, which can cause the detection information to occupy more uplink resources.

With reference to the first aspect, in certain implementation manners of the first aspect, determining whether a channel quality of an uplink traffic channel is in a quality steady state according to a set of parameter values includes: taking the absolute value of the difference value of two parameter values at adjacent moments in the parameter value set as the variation value of the parameter to obtain a plurality of variation values of the parameter; taking the average value of a plurality of variation values of the parameter as the variation average value of the parameter; under the condition that the variation average value of the parameters is not larger than the variation threshold value corresponding to the parameters, determining that the channel quality of the uplink service channel is in a quality stable state; and under the condition that the variation average value of the parameters is larger than the variation threshold value corresponding to the parameters, determining that the channel quality of the uplink service channel is not in a quality stable state.

Based on the scheme, the absolute value of the difference value between two parameter values at adjacent moments in the parameter value set is taken as a parameter variation value to obtain a plurality of parameter variation values, then the average value of the plurality of parameter variation values is taken as a parameter variation average value, and under the condition that the parameter variation average value is not larger than a parameter corresponding variation threshold value, the fact that the channel quality of an uplink service channel is changed less is indicated, and the channel quality can be determined to be in a quality stable state; and under the condition that the variation average value of the parameters is larger than the variation threshold value corresponding to the parameters, the channel quality variation of the uplink service channel is larger, and the fact that the channel quality is not in a quality stable state can be determined.

With reference to the first aspect, in certain embodiments of the first aspect, the method further comprises: acquiring a signal-to-interference-plus-noise ratio (SINR) value set corresponding to a terminal and a Time Advance (TA) value set corresponding to the terminal; the SINR value set comprises SINR values at a plurality of moments in a first time period, and the TA value set comprises TA values at a plurality of moments in the first time period; and determining whether the network environment of the terminal in the first time period is in an environment stable state according to the SINR value set and the TA value set.

Based on this scheme, since whether the network environment of the terminal is in an environment stable state is related to the transmission quality and capacity of the wireless channel between the terminal and the base station, and the distance between the terminal and the base station, and SINR can be used to evaluate the transmission quality and capacity of the wireless channel between the terminal and the base station, TA reflects the propagation time of the wireless signal from the terminal to the base station, and the distance between the terminal and the base station can be evaluated, it can be determined whether the network environment of the terminal is in a quality stable state in the first period from the SINR set and the TA set.

With reference to the first aspect, in certain implementation manners of the first aspect, determining whether a network environment of the terminal in a first period of time is in an environment stable state according to the SINR value set and the TA value set includes: taking the absolute value of the difference value of two SINR values at adjacent moments in the SINR value set as the fluctuation value of the SINR to obtain a plurality of fluctuation values of the SINR, and taking the absolute value of the difference value of two TA values at adjacent moments in the TA value set as the fluctuation value of the TA to obtain a plurality of fluctuation values of the TA; taking an average value of a plurality of fluctuation values of the SINR as a fluctuation average value of the SINR, and taking an average value of a plurality of fluctuation values of the TA as a fluctuation average value of the TA; determining that the network environment of the terminal is in an environment stable state in a first time period under the condition that the fluctuation average value of the SINR is smaller than the fluctuation threshold value corresponding to the SINR and the fluctuation average value of the TA is smaller than the fluctuation threshold value corresponding to the TA; and determining that the network environment of the terminal in the first time period is not in an environment stable state under the condition that the fluctuation average value of the SINR is not smaller than the fluctuation threshold value corresponding to the SINR and/or the fluctuation average value of the TA is not smaller than the fluctuation threshold value corresponding to the TA.

Based on the scheme, when the fluctuation average value of the SINR is smaller than the fluctuation threshold value corresponding to the SINR and the fluctuation average value of the TA is smaller than the fluctuation threshold value corresponding to the TA, the transmission quality and capacity of the wireless channel between the terminal and the base station and the distance between the terminal and the base station can be considered to be basically unchanged, so that the network environment of the terminal in the first time period can be determined to be in an environment stable state. When the average value of the fluctuation of the SINR is not smaller than the fluctuation threshold corresponding to the SINR and/or the average value of the fluctuation of the TA is not smaller than the fluctuation threshold corresponding to the TA, it can be considered that the transmission quality and capacity of the wireless channel between the terminal and the base station and/or the distance between the terminal and the base station have changed greatly, and therefore, it can be determined that the network environment of the terminal in the first period is not in an environment stable state.
