Fig. 1 schematically illustrates a remote covering unit employed by some embodiments of the present invention. As shown in fig. 1, the remote covering unit 10 is connected to a distribution network 11. Through the coupler 101, the signal is divided into three paths, one path of 2G/3G/4G signal is transmitted and received through the 2G/3G/4G antenna 110, and two paths of 5G signals are transmitted and received through the two 5G-MIMO channels by using the 5G antennas 120 and 130.

It will be understood by those skilled in the art that FIG. 1 is exemplary only, and not intended to limit the present invention in any way.
Figure 2 illustrates a flow diagram of a remote coverage unit control method according to some embodiments of the present invention. As shown in fig. 2, the remote coverage unit control method of this embodiment includes steps S202 to S204.
In step S202, the uplink traffic demand in the coverage area of the remote coverage unit is determined by analyzing the 5G uplink signal acquired by the remote coverage unit. The uplink traffic demand can be represented by, for example, the power of an uplink signal, information on resource blocks occupied by the uplink signal, and the like.
In step S204, the switch of the 5G channel of the remote coverage unit is controlled according to the uplink traffic demand.
In some embodiments, when the business traffic demand is greater than a preset value, the 5G channel is kept in an open state; and when the uplink service demand is less than a preset value, closing the 5G channel. When the number of the 5G channels is more than two, part of the 5G channels are closed (for example, one 5G channel is closed), so that the remote covering unit is in a state with low power consumption but available 5G functions.
The above embodiments may be implemented by the communication module of the remote coverage unit itself, e.g. by the baseband processing module. Therefore, the control of the 5G channel switch can be realized by utilizing the communication module built in the remote covering unit control device, and the terminal is not required to be additionally provided with an additional module, so that the deployment cost and the complexity are reduced.
By the method of the embodiment, the switch of the 5G channel can be controlled according to the uplink service demand of the user in the coverage area, so that the energy consumption can be reduced on the premise of meeting the use requirements of the user. In addition, the invention realizes an energy-saving control scheme based on each remote coverage unit, and is more flexible and accurate compared with a cell-level control scheme.
An embodiment for determining the uplink traffic demand in the coverage area of a remote coverage unit is illustratively described below with reference to fig. 3.
Fig. 3 shows a flow diagram of an uplink traffic demand determination method according to some embodiments of the present invention. As shown in fig. 3, the uplink traffic demand determination method of this embodiment includes steps S302 to S306.
In step S302, the 5G uplink signal acquired by the remote coverage unit is converted into a digital signal.
In some embodiments, when there are more than two 5G channels in the remote coverage unit, the 5G uplink signals acquired from the more than two 5G channels are coupled; and performing down-conversion and analog-to-digital conversion on the coupled uplink signals to generate digital signals of 5G uplink signals.
In step S304, Inverse Fast Fourier Transform (IFFT) is performed on the digital signal of the 5G uplink signal, so as to obtain the power of each RE (Resource Element) of the uplink signal.
In step S306, the uplink traffic demand of the 5G uplink signal of the remote coverage unit is determined according to the power of each RE.
In some embodiments, the uplink traffic demand includes at least one of a reference power of the 5G uplink signal, a number of reference RBs (Resource Block). The power of the reference RB is greater than a preset RB power threshold. According to the 3GPP protocol standard, one channel bandwidth contains the maximum number of RBs. In the actual resource scheduling process, a single user does not necessarily use all RBs. The power value of the used RB is larger than the threshold value, which greatly contributes to the total power, and the power of the unused RB is smaller than the threshold value, which can be ignored. Therefore, when determining the uplink traffic demand using the uplink power or the number of RBs, only the RB having a larger power may be considered.
In some embodiments, the reference power and the number of reference RBs are determined in the following manner:
1. traversing the power of each RE in the 5G uplink signal acquired by the remote coverage unit, and marking the RE larger than the RE power threshold as a reference RE;
2. integrating the power of the reference RE corresponding to each RB, and taking the integration result as the reference power of the corresponding RB;
3. marking the RB with the reference power larger than the RB power threshold as a reference RB;
4. integrating the power of the reference RB, and taking the integration result as the reference power of the 5G uplink signal;
5. the number of reference RBs is calculated.
Thus, the uplink traffic demand can be determined more accurately. In addition, the information of the reference power and the number of the reference RBs can not only qualitatively analyze whether the coverage area has users, but also quantitatively analyze the size of the uplink resource demand of the coverage area.
The invention exemplarily provides three judgment methods for closing control of the 5G channel of the remote covering unit. An embodiment of the present invention for controlling the switching of the 5G channel of the remote covering unit is described below with reference to fig. 4.
Fig. 4 illustrates a flow diagram for controlling the switching of the 5G channel of the remote coverage unit according to some embodiments of the present invention. As shown in fig. 4, the control method of this embodiment includes steps S402 to S410.
In step S402, the uplink traffic demand of the remote coverage unit is determined by analyzing the 5G uplink signal acquired by the remote coverage unit.
In step S404, it is determined whether the reference power of the 5G uplink signal is less than a preset power. If yes, go to step S410; if not, step S406 is performed.
For example, when there are no users or few users in the coverage area of the remote coverage unit, the reference power of the 5G uplink signal may be smaller than the preset power. It is considered that one 5G channel is turned off at this time to save power consumption.
In step S406, it is determined whether the reference RB number of the 5G uplink signal is less than a preset number. If yes, go to step S410; if not, step S408 is performed.
For example, when the uplink traffic of the terminal in the coverage area of the remote coverage unit is low, the number of RBs of the 5G uplink signal is also low. It is considered that one 5G channel is turned off at this time to save power consumption.
In step S408, it is determined whether a plurality of remote coverage units adjacent to each other serve the same user. If yes, go to step S410; if not, the flow ends.
In some embodiments, uplink traffic demand within the coverage of the first remote coverage unit and the second remote coverage unit is obtained to determine whether the resource numbers of the reference RBs of the first remote coverage unit and the second remote coverage unit are the same. For example, a master-slave relationship may be set for two remote coverage units that are adjacent. The baseband processing module of the master remote coverage unit may obtain an analysis result of the baseband processing module of the slave remote coverage unit on the 5G uplink signal. Upon analysis, if the 5G channel of the slave remote cover unit needs to be closed, the master remote cover unit may send a corresponding indication to the slave remote cover unit.
In step S410, one 5G channel of the remote cover unit is closed.
In some embodiments, for the case of step S408, in case that the resource numbers of the reference RBs of the first remote coverage unit and the second remote coverage unit are the same, one 5G channel of the remote coverage unit with the smallest reference power for the 5G uplink signal is turned off. Therefore, the remote covering unit with the lower reference power of the 5G uplink signal closes one channel, so as to save energy consumption.
Steps S402, S406 and S408 provide three specific control methods. One or more of these may be selected as desired by those skilled in the art, or may be used in combination with other control schemes, and will not be described in detail herein.
