Figure 3 shows a block diagram of a base station in accordance with one embodiment of the present invention.

As shown in FIG. 3, a base station 300 according to an embodiment of the present invention includes the above technical party. The power consumption control system 200 for a base station according to any one of the preceding claims, the base station 300 has the same technical effect as the power consumption control system 200 for a base station according to any one of the above aspects, This will not be repeated here.

In the power consumption control method for the base station, according to the load amount of the base station, the CA bandwidth combination (equivalent to the bandwidth of each carrier) and the reduction are changed without changing the CA download rate (corresponding to the carrier combination bandwidth). The number of carriers; then adjust the operating voltage of the base station according to the reduced subcarriers, thereby achieving the purpose of controlling the power loss (power consumption) of the base station.

Specifically, when the base station traffic load is insufficient, the base station can adjust the carrier combination (CA bandwidth combination) and the number of subcarriers of the UE (User equipment) without reducing the CA rate. For example, if the number of carriers of a UE is four, and the CA bandwidth combination is 15M+15M+10M+20M, one subcarrier can be reduced without reducing the download rate, and the bandwidth combination is adjusted to 20M+20M+20M, namely: 15M+15M+10M+20M=20M+20M+20M, so the CA download rate will remain unchanged. Thus, one carrier can be turned off, and then the operating voltage of the base station can be adjusted to reduce the power loss of the base station.

Of course, this method is also not applicable. For example, the original UE has only two carriers, and the bandwidth combination is 20M+20M. In this case, the number of carriers cannot be reduced (the maximum bandwidth of each carrier is 20M), that is, It is said that when the operation of reducing the number of carriers can be performed under the condition that the existing carrier combination bandwidth is kept unchanged according to the number of carriers of the terminal and the bandwidth of each carrier, specifically, the carrier used by the terminal should be satisfied. The number should be at least 2, and the bandwidth of each of the used carriers cannot be the maximum bandwidth threshold (ie, 20M).

Therefore, the base station detects the number of UEs and the bandwidth combination (ie, detecting the carrier usage parameters) at the beginning, and if it does not reduce the CA rate and downloads the big data (ie, the current data traffic of the terminal should reach the pre- The threshold value, for example, 500 M) can be reduced by controlling the bandwidth combination, and the method shown in FIG. 4 is performed, specifically including:

Step 402: The base station detects the number of carriers and the bandwidth combination of the UE, that is, detects the base station. Carrier usage parameters of any terminal served;

Step 404, when it is determined that the big data is downloaded, calculating whether the reduced carrier number and the adjusted bandwidth combination are feasible without reducing the CA rate, that is, if yes, executing step 406, otherwise ending, that is, when determining the current data service When the quantity is less than the preset threshold, determining whether to reduce the number of carriers in a case where the carrier combination bandwidth is kept unchanged according to the number of carriers and the bandwidth of each carrier;

Step 406: Adjust the carrier bandwidth combination of the terminal, and turn off the excess subcarriers, that is, when it is determined that the number of the carriers is reduced while maintaining the carrier combination bandwidth is unchanged, determine the carrier to be turned off;

Step 408, adjusting the working voltage of the base station according to the off carrier. At this time, the carrier is reduced, and the corresponding base station transmission power is reduced, that is, the working voltage of the base station is reduced, thereby achieving the purpose of controlling the base station power loss, that is, according to The carrier to be turned off adjusts an operating voltage of the base station.

The technical solution of the present invention can reduce the excess subcarriers by flexibly changing the CA bandwidth combination without reducing the CA download rate, thereby achieving the purpose of controlling the base station power loss.

The technical solution of the present invention is described in detail above with reference to the accompanying drawings. It is possible to effectively change the carrier bandwidth combination and reduce the number of carriers without changing the data transmission rate according to the load of the base station, thereby adjusting the work of the base station according to the reduced carrier.
