[ detailed description ] embodiments
Referring to fig. 1, the present embodiment provides a distributed base station, which includes a Baseband Unit (BU)10, an Extension Unit (EU)20 connected to the Baseband Unit (BU)10, and a Radio Unit (RU)30 connected to the Extension Unit (EU) 20. The Extension Unit (EU)20 and the Radio Unit (RU)30 are typically several.
A radio frequency unit (RU)30 includes a detection module 32, a comparison module 34, and a control module 36.
The detection module 32 is configured to detect uplink energy received in an operating frequency band within a coverage area of a radio frequency unit (RU) 30. The Uplink energy is the sum of energies of an Uplink PRACH (Physical Random Access Channel) Channel, an Uplink PUCCH (Physical Uplink Control Channel) Channel, and an Uplink PUSCH (Physical Uplink Shared Channel).
The comparing module 34 is configured to compare the uplink energy value detected by the detecting module 32 with a preset threshold value.
The control module 36 is configured to turn off the transmission power of at least a portion of the downlink channels of the radio frequency unit (RU)30 when the uplink energy value is smaller than a preset threshold value, and to recover the transmission power of at least a portion of the downlink channels of the radio frequency unit (RU)30 when the uplink energy value is greater than or equal to the preset threshold value.
In this embodiment, the control module 36 is configured to close the transmission powers of all downlink channels of the radio frequency unit (RU)30 except the downlink broadcast channel when the uplink energy value is smaller than the preset threshold value, and to restore the transmission powers of all downlink channels of the radio frequency unit (RU)30 except the downlink broadcast channel when the uplink energy value is greater than or equal to the preset threshold value.
For example, in practical applications, the detection module 32 detects uplink energy received in an operating frequency band within the coverage of the radio frequency unit (RU) 30. Comparing the uplink energy value detected by the detection module 32 with a preset threshold value by the comparison module 34, if the uplink energy value is smaller than the preset threshold value, it is determined that there is no mobile terminal communication service requirement in the coverage area of the radio frequency unit (RU)30, then closing the transmission power of all downlink channels of the radio frequency unit (RU)30 except for the downlink broadcast channel by the control module 36, and the ratio of the energy consumption of the downlink broadcast channel to the energy consumption of all other downlink channels is 1: 200, the control module 36 closes the transmission power of all downlink channels except the downlink broadcast channel of the radio frequency unit (RU)30, so as to reduce the energy consumption of the radio frequency unit (RU)30, and thus, the energy consumption of the distributed base station can be reduced, and the purposes of energy saving and emission reduction are achieved. If the uplink energy value is greater than or equal to the preset threshold value, it is determined that there is a mobile terminal communication service requirement in the coverage area of the radio frequency unit (RU)30, and the control module 36 recovers the transmission power of all downlink channels of the radio frequency unit (RU)30 except for the downlink broadcast channel, so that the mobile terminal user in the coverage area of the radio frequency unit (RU)30 can normally perform the communication service.
In the radio frequency unit (RU)30, all Downlink channels except for the Downlink broadcast Channel include a Downlink PDSCH (Physical Downlink Shared Channel) Channel, a Downlink PDCCH (Physical Downlink Control Channel) Channel, a Downlink PCFICH (Physical Control Format Indicator Channel) Channel, a Downlink PHICH (Physical HARQ Indicator Channel) Channel, and a Downlink PMCH (Physical Multicast Channel).
Referring to fig. 2, the present invention further provides a method for saving energy of a distributed base station, including the following steps:
s2, keeping the downlink broadcast channel of the Radio Unit (RU)30 turned on. The mobile terminal transmits an uplink signal only if a downlink broadcast channel of a Radio Unit (RU)30 is turned on.
S4, detecting the uplink energy received in the working frequency band within the coverage area of the radio frequency unit (RU)30 through the detection module 32. The uplink energy is the sum of the energy of the uplink PRACH, the uplink PUCCH and the uplink PUSCH.
S6, comparing the uplink energy value detected by the detecting module 32 with a preset threshold value by the comparing module 34 of the radio frequency unit (RU)30, if the uplink energy value is smaller than the preset threshold value, then it is determined that there is no mobile terminal communication service requirement in the coverage area of the radio frequency unit (RU)30, and then step S8 is entered.
S8, the control module 36 of the radio frequency unit (RU)30 turns off the transmission power of at least a part of the downlink channels, so as to reduce the energy consumption of the radio frequency unit (RU)30, and thus, the energy consumption of the distributed base station can be reduced, and the purpose of saving energy is achieved. In this embodiment, the control module 36 of the radio frequency unit (RU)30 turns off the transmission power of all downlink channels of the radio frequency unit (RU)30 except for the downlink broadcast channel, so as to minimize the power consumption of the radio frequency unit (RU) 30.
In step S6, if the uplink energy value is greater than or equal to the preset threshold value, it is determined that there is a mobile terminal communication service requirement in the coverage area of the Radio Unit (RU)30, then the method proceeds to step S10:
the control module 36 of the Radio Unit (RU)30 recovers the transmission power of at least a portion of the downlink channel thereof S10 so that the mobile terminal users in the coverage area of the Radio Unit (RU)30 can normally conduct communication services. In the present embodiment, the transmission power of all downlink channels of the radio frequency unit (RU)30 except for the downlink broadcast channel is restored by the control module 36 of the radio frequency unit (RU) 30.
In the radio frequency unit (RU)30, all other downlink channels except the downlink broadcast channel include a downlink PDSCH channel, a downlink PDCCH channel, a downlink PCFICH channel, a downlink PHICH channel, and a downlink PMCH channel.
The invention realizes the detection of the uplink energy received in the working frequency band within the coverage range of the radio frequency unit (RU)30, the comparison of the detected uplink energy value with the preset threshold value and the corresponding control of the transmitting power of the downlink channel according to the comparison result by the radio frequency unit (RU)30, thereby realizing the accurate control of the energy consumption of the radio frequency unit (RU)30, ensuring the communication service experience of a mobile terminal user, reducing the energy consumption of the radio frequency unit (RU)30, saving the energy consumption of a distributed base station to the maximum extent, improving the energy efficiency of the distributed base station and reducing the cost.
