Description
Technical Field
The present application relates to the field of communications technologies, and in particular, to a method and an apparatus for controlling a radio frequency antenna switch.
Background
Energy conservation and emission reduction are important issues in the development of the world at present, and the communication industry is no exception. In all network devices, the power consumption of the base station accounts for a large proportion, and therefore, reducing the power consumption of the base station device is the key to energy conservation and emission reduction of the network devices.
For a base station of a TD-SCDMA (Time Division-Synchronous Code Division Multiple Access) or TD-LTE (Time Division Long Term Evolution) system, one of the most effective methods for saving energy is to close a radio frequency antenna switch under a Time slot or a subframe without service data. Generally, the quiescent current of the base station rf antenna is about 40-60% of the operating current in the full power transmission state, so that if the rf antenna transmission channel corresponding to the downlink timeslot or subframe when there is no service data is closed, a significant power saving effect can be obtained.
In the prior art, a general method generally detects data transmitted by each rf antenna at a specific location of a baseband unit, and determines whether a segment needs to close a corresponding transmitting channel, so as to achieve the purpose of saving energy. Chinese patent application CN102904626A discloses a method and apparatus for controlling power amplifier switch of antenna, which judges whether each antenna bears service data in the current downlink time slot through a threshold judging module, and after updating the bearing status identifier of each antenna according to the judging result, sends the bearing status identifier of each antenna to the switch control module in the current downlink time slot; and then the switch control module controls the power amplifier switch of each antenna according to the bearing state identification of each antenna, thereby ensuring the real-time performance of the power amplifier switch control. The method for closing the transmitting channel of the radio frequency antenna can achieve real-time performance, but the adjustment of the closing position of the switch is to preliminarily estimate a time delay value from a data detection position to an empty port, and on the basis, the time delay value is continuously adjusted by trying to find an approximately accurate time delay value to be matched by a manual observation instrument, so that the generation position of a switch closing control signal is adjusted to make up the difference from the data detection position to the empty port, and the accuracy of the closing position of the switch is poor. In addition, the method cannot automatically adapt to different types of hardware equipment or differences of different link processing time delays caused by different data bearing functions in the same type of hardware equipment, and when the hardware difference is large or the software processing function difference is large, the process needs to be repeated, so that the accuracy is poor, and time and labor are wasted.

Detailed Description
In order to make the aforementioned objects, features and advantages of the present application more comprehensible, the present application is described in further detail with reference to the accompanying drawings and the detailed description.
Referring to fig. 1, a flowchart illustrating a first step of a control method for a radio frequency antenna switch according to an embodiment of the present application is shown, which may specifically include the following steps:
typically, the base station mainly includes parts such as a baseband unit bbu (baseband unit) and a remote radio unit rru (remoterf unit). The remote radio unit includes an interface section, an intermediate frequency section, a radio frequency section, and a power amplifier. The interface part is a baseband data interface unit between the remote radio frequency unit and the baseband unit and mainly completes link protocol analysis and control and processing of data streams; the intermediate frequency part mainly completes DDC (Digital Down Conversion), DUC (Digital Up Conversion), DPD (Digital Predistortion), A/D Conversion, D/A Conversion and the like; the radio frequency part mainly completes modulation and demodulation; the power amplifier is used for power amplification and the like.
The base station may be further classified as a single mode base station or a dual mode base station, etc. according to the type of the service data carried. For example, a base station carrying only TD-SCDMA service data (3G service data) or TD-LTE service data (4G service data) is a single-mode base station, and a base station capable of carrying both TD-SCDMA and TD-LTE service data is a dual-mode base station.
The base station of the TD-SCDMA system adopts a TDD (Time Division duplex) working mode, and each subframe consists of three special Time slots (DwPTS, GP and UpPTS) and 7 service Time slots (TS0-TS 6). The DwPTS and the UpPTS are respectively used for downlink synchronization and uplink synchronization, and do not bear user data; GP is used for propagation delay protection in the uplink synchronization process; the service time slot (TS0-TS6) is used for transmitting user data and control information, the TS0 is fixed and used as a downlink time slot for transmitting broadcast information and control information, and the TS1 is fixed and used as an uplink time slot; other traffic slots (TS2-TS6) may be configured upstream or downstream as desired. Due to different radio frame structures, the base station of the TD-LTE system completes transmission of uplink and downlink radio frame data through subframe symbols.
In this embodiment of the present application, in order to accurately control the turning off of the rf antenna switch, downlink wireless frame data sent by a current subframe or timeslot may be received first.
102, calculating a time delay value of the downlink wireless frame data;
since the turn-off region of the rf antenna switch is determined according to the matching with the non-service data of a certain subframe or timeslot at the air interface, in this embodiment of the present application, the time delay value of the downlink wireless frame data reaching the air interface may be calculated first.
In a preferred embodiment of the present application, the step of calculating the delay value of the downlink wireless frame data may include the following sub-steps:
and a substep 1021, calculating the time delay value of the downlink wireless frame data from the baseband to the air interface in real time.
Generally, no matter whether downlink wireless frame data is non-zero or not, there is a time delay from the baseband to the air interface, and therefore, in this embodiment of the application, in order to accurately adjust the position of the switch-off signal of the radio frequency antenna, a time delay value of the downlink wireless frame data from the baseband to the air interface may be calculated in real time.
In another preferred embodiment of the present application, the sub-step of calculating in real time a delay value of the downlink wireless frame data from the baseband to the air interface may further include:
s11, counting the number of clocks between the channel frame header and the air interface frame header in real time;
and S12, determining the time delay value of the downlink wireless frame data from the baseband to the air interface according to the number of the clocks.
Generally, in order to ensure normal communication between the base station and the terminal, the frame header of the radio frame of the baseband data needs to be adjusted, so that the starting position of the frame data accurately appears at the air interface at the frame header of the air interface, and at this time, the base station and the terminal can only realize normal communication. The associated frame header is a pulse which is aligned with the baseband radio frame data and indicates the interval of the starting position of the radio frame by 5ms or 10ms, for example, the beginning of the sub-frame 0, and the null frame header is the starting time point of the radio frame sent by the radio frequency antenna.
Therefore, for any base station or terminal in normal communication, the time difference between the channel associated frame head and the air interface frame head is necessarily the time required by any baseband data to be transmitted from the baseband to the air interface, and the control signal generated by detecting any point of the baseband data can be accurately adjusted through the time difference between the channel associated frame head and the air interface frame head, so that the control signal and the data synchronously reach the air interface, and the accurate control of the radio frequency switch is realized.
Because the number of clocks between the channel-associated frame header and the air interface frame header can accurately represent the time difference between the channel-associated frame header and the air interface frame header, in this embodiment of the present application, the number of clocks between the channel-associated frame header and the air interface frame header can be counted in real time, and then the delay value of the downlink wireless frame data transmitted from the baseband to the air interface is determined according to the number of clocks.
generally, for a downlink time slot or a subframe in which a radio frequency antenna does not carry service data, a base station may turn off a switch related to transmission of the radio frequency antenna in the downlink time slot or the subframe, thereby achieving energy saving and consumption reduction of a system.
In the embodiment of the application, zero data with a specific length can be sent through the current subframe or time slot, and then whether downlink wireless frame data is non-service data or not is judged according to whether the subframe or time slot of the downlink wireless frame data received at a preset detection position contains the zero data with the specific length or not; the zero data is data having a value of zero. One skilled in the art may also determine other data types according to actual situations, and the present application is not limited to this.
Generally, the preset detection position may be located before the air interface, and of course, a person skilled in the art may also agree on an appropriate detection mode according to actual needs, so as to set different detection positions.
Specifically, for the TD-SCDMA base station, 16chip zero data may be sent at a specific position of a current time slot, and then it is detected in real time at a preset detection position in a data path whether to have the appointed data, or the zero data exceeding 16 chips is continuously sent at the specific position of the current time slot, for example, 20 chips, as long as it is detected that all the continuous 16chip data are zero at the preset detection position, it may be determined that the time slot does not send the traffic data, and it may be considered that a radio frequency antenna switch corresponding to the time slot may be turned off. For the TD-LTE base station, the length of the zero data transmitted at a specific position of the current subframe may be 32ts, where ts refers to LTE sampling points, and the duration of one ts is a period of 30.72MHz clock. For the convenience of detection, a person skilled in the art may determine the length of the transmitted zero data according to actual needs, and this application is not limited in this respect.
And step 104, closing the switch of the radio frequency antenna according to the time delay value.
In this embodiment of the present application, after obtaining the delay value when the downlink radio frame data reaches the air interface, the switch of the radio frequency antenna may be turned off according to the delay value.
In a preferred embodiment of the present application, the step of turning off the switch of the rf antenna according to the delay value may specifically include the following sub-steps:
substep 1041, generating said radio frequency antenna switch off signal;
in a specific implementation, the baseband wireless frame data may be read from the buffer at the position of the associated frame header and transmitted to the radio frequency antenna for transmission, and meanwhile, each preset detection position is determined to detect the downlink wireless frame data with the associated frame header as a reference, thereby generating a switch-off signal.
Substep 1042, adjusting the position of the switch closing signal according to the time delay value;
in this embodiment of the present application, after obtaining the time delay value when the non-service data reaches the air interface, the position of the radio frequency antenna switch closing signal corresponding to the current time slot or subframe symbol may be automatically adjusted according to the time delay value.
In a preferred embodiment of the present application, the sub-step of adjusting the position of the switch-off signal according to the time delay value may further include:
and S21, according to the time delay value, compensating the time of the downlink wireless frame data transmitted from the baseband to the air interface so as to adjust the position of the switch closing signal.
In a specific implementation, after determining a delay value of the downlink wireless frame data from the baseband to the air interface, the time of the downlink wireless frame data from the baseband to the air interface may be compensated according to the delay value, so as to implement accurate adjustment of a switch off signal position.
Sub-step 1043, in said position, closing the switch of said radio frequency antenna.
In the embodiment of the application, the time delay value of the downlink wireless frame data reaching the air interface is calculated in real time, and when the downlink wireless frame data is judged to be service-free data, the closing position of the radio frequency antenna switch is adjusted according to the time delay value, so that the energy-saving closing area of the base station can be automatically and accurately determined.
Secondly, the time delay value is determined by counting the number of clocks between the channel frame header and the air interface frame header in real time, different link time delays between different types of hardware equipment and data processing time delay in a single-mode and a double-mode can be compatible, the defect that other similar schemes need to manually debug and determine the time delay value is overcome, self-adaption is strong, manual intervention is not needed, and debugging time is saved.
Referring to fig. 2, a flowchart illustrating steps of a second embodiment of a method for controlling a radio frequency antenna switch according to the present application is shown, which may specifically include the following steps:
generally, for a downlink subframe or a time slot in which a radio frequency antenna does not carry service data, a base station may close a power amplifier switch of the radio frequency antenna at the downlink subframe or the time slot, thereby achieving energy saving and consumption reduction of a system. Therefore, in the embodiment of the present application, in order to determine whether downlink wireless frame data transmitted in a current subframe or time slot is non-service data, zero data of a specific length may be first transmitted through the current subframe or time slot.
generally, in order to ensure normal communication between the base station and the terminal, the frame header of the radio frame of the baseband data needs to be adjusted, so that the starting position of the frame data accurately appears at the air interface at the frame header of the air interface, and at this time, the base station and the terminal can only realize normal communication. Therefore, for any base station or terminal in normal communication, the time difference between the channel associated frame head and the air interface frame head is necessarily the time required by any baseband data to be transmitted from the baseband to the air interface, and the control signal generated by detecting any point of the baseband data can be accurately adjusted through the time difference between the channel associated frame head and the air interface frame head, so that the control signal and the data synchronously reach the air interface, and the accurate control of the radio frequency switch is realized.
In a specific implementation, the time difference between the associated frame header and the air interface frame header may be obtained by counting the number of clocks between the associated frame header and the air interface frame header in real time.
in this embodiment of the present application, after the number of clocks between the associated frame header and the air interface frame header is determined, a delay value of the downlink wireless frame data transmitted from the baseband to the air interface may be further determined according to the number of clocks.
For example, if the counted number of clocks between the associated frame header and the null frame header is 100, and each clock represents 8 nanoseconds (ns), it may be determined that the delay value of the downlink wireless frame data from the baseband to the null is 800 nanoseconds.
in this embodiment of the present application, after receiving downlink wireless frame data sent by a current subframe or timeslot, it may be determined whether the downlink wireless frame data is non-service data by determining whether a subframe or timeslot of the downlink wireless frame data received at a preset detection position contains zero data of the specific length.
Generally, the preset detection position may be located before the air interface, and of course, a person skilled in the art may also agree on an appropriate detection mode according to actual needs, so as to set different detection positions.
Specifically, for the TD-SCDMA base station, 16chip zero data may be sent at a specific position of a current time slot, and then it is detected in real time at a preset detection position in a data path whether to have the appointed data, or the zero data exceeding 16 chips is continuously sent at the specific position of the current time slot, for example, 20 chips, as long as it is detected that all the continuous 16chip data are zero at the preset detection position, it may be determined that the time slot does not send the traffic data, and it may be considered that a radio frequency antenna switch corresponding to the time slot may be turned off. For the TD-LTE base station, the length of the zero data transmitted at a specific position of the current subframe may be 32ts, where ts refers to LTE sampling points, and the duration of one ts is a period of 30.72MHz clock. For the convenience of detection, a person skilled in the art may determine the length of the transmitted zero data according to actual needs, and this application is not limited in this respect.
If the downlink wireless frame data is judged to be non-service data, the baseband wireless frame data can be read from the cache at the position of the associated frame head and transmitted to the radio frequency antenna for sending, and meanwhile, each preset detection position is determined to detect the downlink wireless frame data by taking the associated frame head as a reference, so that a switch closing signal is generated.
in a specific implementation, after determining a delay value of the downlink wireless frame data from the baseband to the air interface, the time of the downlink wireless frame data from the baseband to the air interface may be compensated according to the delay value, so as to implement accurate adjustment of a switch off signal position.
As shown in fig. 3, which is a schematic diagram of adjusting a switch-off signal of the method for controlling a radio frequency antenna switch according to the present application, 301 to 303 are examples of an air-interface frame header, a channel-associated frame header, and baseband data in sequence, 304 is an example of a preset detection position corresponding to the baseband data, and 305 to 306 are examples of a switch-off position corresponding to the preset detection position and a switch-off position adjusted according to the delay value, respectively.
