Description
Technical Field
The present disclosure relates to the field of communications technologies, and in particular, to a transceiver control method, apparatus, device, and storage medium.
Background
In a mobile communication system in a time division duplex (Time Division Duplexing, TDD) mode, a TDD base station generally uses a transceiver (having a function of receiving a signal and transmitting a signal) to alternately operate in a transmitting state and a receiving state, so as to implement signal transmission and reception. After the transceiver is converted from the transmitting state to the receiving state, the downlink signals of the adjacent base stations are overlapped to generate interference, and the interference may exceed the maximum receiving power allowed by the TDD base station transceiver, thereby causing the saturated blocking of the transceiver and causing the transceiver to fail to work normally. To combat saturation blocking, typically automatic gain control (Automatic Gain Control, AGC), the transceiver is prevented from operating in saturation by reducing the receive amplifier gain when the transceiver detects that the received power is too high.
In the method, because the AGC circuit detects that the delay exists in the detection and effect process of performing gain control on the input signal which is too high, the risk of saturation blocking still exists before the AGC is effective; moreover, the AGC is affected by the input signal and the interference intensity, if the threshold setting for triggering the AGC is unreasonable, or the duration of the high-intensity input signal and the interference is longer, the normal power amplification is not recovered when the uplink useful signal arrives, so that the sensitivity of the transceiver is reduced; alternatively, when the AGC circuit fails, the saturation blocking suppression capability of the transceiver will be lost. Therefore, when the transceiver is switched from the transmitting state to the receiving state, the downlink signals of the adjacent base stations are superimposed to generate interference, and the saturation blocking of the transceiver is caused.

Detailed Description
The technical solutions in the embodiments of the present application will be described below with reference to the drawings in the embodiments of the present application.
In the description of the present application, "/" means "or" unless otherwise indicated, for example, a/B may mean a or B. "and/or" herein is merely an association relationship describing an association object, and means that three relationships may exist, for example, a and/or B may mean: a exists alone, A and B exist together, and B exists alone. Further, "at least one", "a plurality" means two or more. The terms "first," "second," and the like do not limit the number and order of execution, and the terms "first," "second," and the like do not necessarily differ.
In a mobile communication system in TDD mode, base station receiving signals and transmitting signals are alternately performed in different time slots of the same frequency channel (i.e. the same carrier), the channels of the receiving signals and the transmitting signals are separated by a protection Gap (GP), the configuration of the GP is usually related to the planned maximum coverage distance of the base station, and reasonable configuration of the GP can ensure that terminals at the cell edge of the base station can complete cell access, and meanwhile ensure that downlink signals do not affect uplink signals between base stations within a certain distance interval, and the effect mainly means that after downlink signals of a far-end base station are propagated for a period of time, the downlink signals reach a receiver (i.e. a transceiver) of the other base station in the uplink time slot of the other base station, thereby interfering the accurate reception of uplink useful signals of the other base station.
TDD base stations typically use the same transceiver to alternately operate in a transmit state and a receive state to effect reception and transmission of signals, typically requiring a state transition delay of no more than 10 microseconds for the type of transceiver to transition from a transmit state to a receive state and vice versa. After the transceiver is switched from transmitting to receiving state, if the receiver amplifier is turned on immediately, a large number of downlink signals of adjacent base stations, especially base station signals from some base stations which are not well radio frequency optimized and have direct paths in the range of 3 Km-10 Km, are received, and if the downlink arrival signals of the adjacent stations are superimposed, the downlink arrival signals of the adjacent stations are strong enough, the maximum receiving power allowed by the interfered base station receiver can be exceeded, and thus the saturation blocking of the receiver is caused. Receiver saturation blocking can cause the receiver to fail, and long-term saturation blocking can also cause permanent performance degradation of the receiver.
In order to combat receiver saturation blocking, a common technical means is to prevent the receiver from operating in saturation by reducing the gain of the receiving amplifier when the receiver detects that the received power is too high by AGC.
For example, as shown in fig. 1, in the TDD mobile communication system, downlink signals of the base station 1, the base station 2 and the base station 3 reach the receiver of the base station 4 through propagation, and due to different propagation delays and propagation losses of downlink signals from different base stations, the time and the signal strength of the downlink signals reaching the base station 4 are different. In general, the closer the base station is to, the earlier the propagation delay, the less the signal attenuation. As shown in fig. 2, the downlink signals of the base station 1, the base station 2 and the base station 3 reach the receiver of the base station 4 through propagation, if the downlink signals of the base station 1, the base station 2 and the base station 3 reach the base station 4 in a receiving state (that is, the transceiver is the receiver) of the transceiver of the base station 4, a plurality of arriving signals are overlapped to form the situation shown in fig. 2: exhibiting a gradual decline in time. When the superimposed signal strength exceeds the maximum received power allowed by the receiver, it may cause receiver saturation blocking of the base station 4.
Referring to the requirement of 3GPP on the anti-blocking capability of a base station receiver, for the coexistence of different base station frequencies, the data service rate of an interfered base station cannot be lower than 95% of the peak rate requirement when the interference power reaches-43 dBm under the non-co-sited condition. It is reasonable to infer that for a base station receiver that just meets this anti-blocking requirement, an arriving signal of-43 dBm will cause the receiver amplifier to enter the nonlinear region, while a stronger arriving signal will push the receiver towards saturation.
Taking a 5G TDD base station operating in a 3.5G frequency band as an example, referring to fig. 2, when the receiver of the base station 4 switches from a transmitting state to a receiving state, the corresponding downlink uplink switching time slot may include 14 symbols, specifically configured to be a ratio of downlink time slot, guard time slot, and uplink time slot of 10:2:2, that is, 10 downlink symbols (symbol 0 to symbol 9), 2 GP symbols (symbol 10 and symbol 11), 2 uplink symbols (symbol 12 and symbol 13), and the whole network is time-synchronized.
For each base station transceiver to begin switching from the transmit state to the receive state after it has transmitted the last downlink symbol (i.e., symbol 9) on the downlink-uplink switch slot, the switch should be completed within 10 microseconds. At the 10 th microsecond time corresponding to symbol 10, it receives a downlink signal from a neighboring base station (e.g., base station 1, base station 2, and base station 3) that arrives at the receiver of base station 4 (i.e., the transceiver is in the receiving state) with a propagation delay of 10 microseconds. If the signals arrive directly via a Line of Sight (LOS) propagation model, the neighboring base stations are about 3Km from the receiver of the base station 4, and the spatial propagation LOSs is about 115dB, as estimated by the propagation model.
Reference formula pr=pt+gt-l+gr, where Pt is the transmit power, gt is the transmit antenna gain, L is the spatial propagation loss, and Gr is the receive antenna gain. Gt, gr can reach 18dBi when both the transmit antenna and the receive antenna are positive. For a 5G base station with 3.5G frequency band, the maximum transmitting power can reach 200W/100MHz, and the transmitting power at 20MHz can reach 40W, namely 46dBm. Substituting the above formula, the power pr=pt+gt-l+gr=46+18-115+18= -33dBm to the receiver of the base station 4 may result in the arriving signal being further superimposed if there are multiple similar LOS neighbors, thus being higher than the safety threshold of-43 dBm.
Similarly, if there is a neighbor with LOS condition at a distance of about 6Km, the spatial propagation LOSs is about 122dB, the power to the receiver is about-40 dBm; if there is a neighbor cell with LOS condition at a distance of about 10Km, the space propagation LOSs is about 127dB, the power reaching the receiver is about-45 dBm, and the risk of the superposition of signals of a plurality of cells being higher than-43 dBm is still great; if there is a neighbor cell of LOS condition at a distance of about 15Km, the spatial propagation LOSs is about 134dB, the power reaching the receiver is about-52 dBm, and the risk of being higher than-43 dBm still exists after the superposition of the signals of a plurality of cells; if there are neighbors with LOS conditions at a distance of about 20Km, the spatial propagation LOSs is about 139dB, the power to the receiver is about-57 dBm, and the risk of signals from multiple neighbors being superimposed above-43 dBm is substantially reduced to a safe level.
According to the transceiver control method provided by the embodiment of the application, whether AGC processing is performed to resist possible saturation blocking can be judged without detecting the signal intensity for a period of time, but a time length smaller than GP is set or judged based on the GP configuration size, and the receiver is turned off during the period of time to reduce unnecessary signal reception, so that the aim of avoiding saturation blocking is achieved. The present scheme does not conflict with AGC when the receiver is not in an off state.
The transceiver control method provided by the embodiment of the application can be applied to a transceiver control system. Fig. 3 shows a schematic diagram of a configuration of the transceiver control system. As shown in fig. 3, the transceiver control system 20 includes: a first base station 21, a second base station 22 and a third base station 23. The first base station 21, the second base station 22, and the third base station 23 are configured to configure carriers for different terminals, respectively, to implement information interaction with different terminals. In the embodiment of the present application, the problem of saturation blocking of the transceiver of the third base station 23 is exemplified by the problem that the downlink signals of the first base station 21 and the second base station 22 will interfere with the third base station 23 after being superimposed.
The transceiver control system 20 may be used for the internet of things, and the transceiver control system 20 may correspond to a plurality of base stations, in this embodiment, three base stations are taken as an example for illustration, and the specific number of base stations is not limited in this application.
The first base station 21, the second base station 22 and the third base station 23 may be used for the internet of things, may be base stations corresponding to operators, and may be respectively connected with different terminals to provide data transmission services for the terminals, for example, provide data information required for operation processing for the terminals, so that the terminals provide data processing services for users.
The first base station 21, the second base station 22, and the third base station 23 may be any base station in a mobile communication system, for example, may be a base station in a 4G mobile communication system or a 5G mobile communication system, which is not particularly limited in this application.
A method for controlling a transceiver according to an embodiment of the present application is described below with reference to the accompanying drawings. As shown in fig. 4, a transceiver control method provided in an embodiment of the present application includes S201 to S202:
s201, closing the transceiver in the process of converting the transceiver from a transmitting state to a receiving state based on the proportion of the downlink and uplink conversion time slots corresponding to the transceiver.
The downlink and uplink conversion time slot ratio comprises: downlink time slot, protection time slot, uplink time slot; the downlink time slot is used for transmitting downlink signals, the protection time slot is used for converting from a transmitting state to a receiving state, and the uplink time slot is used for receiving uplink signals.
Optionally, when the transceiver of the base station is converted from the transmitting state to the receiving state, a special time slot, namely a downlink and uplink conversion time slot, needs to be performed, and the downlink and uplink conversion time slot corresponds to a configuration (namely a downlink and uplink conversion time slot matching), specifically, the duration proportion corresponding to the downlink time slot, the protection time slot and the uplink time slot. For example, the ratio of the durations corresponding to the downlink time slot, the guard time slot and the uplink time slot is 10:2:2 or 8:2:2.
Optionally, in the process that the transceiver is converted from the transmitting state to the receiving state, the transceiver can be closed in the protection time slot after the transmission of the downlink signal is completed in the downlink time slot, so as to reduce the reception of unnecessary interference signals, thereby achieving the purpose of avoiding saturation blocking.
It can be understood that after the TDD base transceiver station finishes the transition from the transmitting state to the receiving state, a transceiver off state is added in the protection time slot based on the downlink-uplink transition time slot proportion, so that the transceiver does not amplify the arriving interference signal in the off state, thereby avoiding saturation blocking.
Optionally, turning off the transceiver may include at least one of: turning off the receive filter, turning off the receive amplifier, etc.
S202, determining the duration of the closed state of the transceiver based on the target information, and starting the transceiver to receive an uplink signal when the duration reaches the target duration.
Wherein the target information includes at least one of: the protection time slot corresponds to the protection time length, the conversion time delay corresponding to the transceiver from the transmitting state to the receiving state, the closing time delay corresponding to the transceiver and the opening time delay corresponding to the transceiver.
Optionally, the base station may determine, in advance, a duration of time that the transceiver is in the off state based on at least one of a protection duration corresponding to the protection time slot, a transition delay corresponding to the transceiver from the transmitting state to the receiving state, an off delay corresponding to the transceiver, and an on delay corresponding to the transceiver, so that when an uplink signal arrives, the base station may pre-start receiving and transmitting information to normally receive the uplink signal.
Optionally, the duration of the transceiver in the off state may be a preset fixed duration, or may be a duration calculated by reading a subcarrier configuration and a protection duration corresponding to a protection time slot based on a preset algorithm.
It should be noted that, the preset fixed duration or the duration calculated based on the preset algorithm should ensure that the transceiver is switched from the off state to the on state, and the transceiver is completed when the uplink signal arrives, so that the transceiver enters the normal working mode, and the reception of the uplink signal is ensured.
In one design, the duration is less than or equal to a guard duration corresponding to the guard time slot; as shown in fig. 5, in the method for controlling a transceiver provided in the embodiment of the present application, the method for determining the duration of time that the transceiver is in the off state based on the target information in the step S202 may specifically include S301:
s301, determining a first difference value between a protection time length corresponding to the protection time slot and a conversion time delay corresponding to the transceiver from a transmitting state to a receiving state, and determining a duration time according to the first difference value.
Alternatively, the first difference may be determined directly as the duration.
Optionally, the duration of the transceiver in the closed state is controlled to be less than or equal to the protection duration corresponding to the protection time slot, so that the uplink signal can be timely received and sent when the uplink signal arrives, and the uplink signal can not be missed.
Optionally, the guard duration corresponding to the guard slot may include a duration of at least one symbol, where the duration of one symbol may be calculated according to a subcarrier setting, for example, in LTE and 5G NR, the symbol length corresponding to the 15kHz subcarrier is about 35.714 microseconds.
It can be understood that the duration is obtained by subtracting the transition delay corresponding to the transceiver from the transmitting state to the receiving state from the guard duration corresponding to the guard time slot.
In the embodiment of the application, the duration of the transceiver in the off state can be determined specifically by the difference between the protection duration corresponding to the protection time slot and the conversion time delay corresponding to the transceiver from the transmitting state to the receiving state, so that when the uplink signal arrives, the transceiver can be controlled to be in the on state in time to receive the uplink signal.
In one design, as shown in fig. 6, in a transceiver control method provided in the embodiment of the present application, the method of determining the duration according to the first difference in step S301 may specifically include S401:
s401, determining a second difference value between the first difference value and the corresponding opening time delay of the transceiver, and determining the second difference value as the duration.
Optionally, the corresponding opening time delay when the transceiver is switched from the off state to the on state may be further set aside, so that on the basis of determining the first difference between the protection time duration corresponding to the protection time slot and the conversion time delay corresponding to the transceiver from the transmitting state to the receiving state, the more accurate duration (i.e., the fourth difference) of the transceiver in the off state is obtained by subtracting the opening time delay corresponding to the transceiver from the first difference.
In this embodiment of the present application, specifically, a first difference between a protection duration corresponding to a protection time slot and a conversion delay corresponding to a transceiver from a transmitting state to a receiving state may be determined, and a second difference between the first difference and an opening delay corresponding to the transceiver may be further determined, so that the second difference is determined as a duration of the transceiver in an off state, so that when an uplink signal arrives, the transceiver may be controlled to be in an on state in time, so as to receive the uplink signal.
In one design, as shown in fig. 7, in a transceiver control method provided in the embodiment of the present application, the method of determining the duration according to the first difference in step S301 may specifically include S501:
s501, determining a third difference value between the first difference value and the closing time delay corresponding to the transceiver, and determining the third difference value as the duration.
Optionally, the corresponding closing time delay when the transceiver is in the closed state from the open state may be further set aside, so that on the basis of determining the first difference between the protection time duration corresponding to the protection time slot and the conversion time delay corresponding to the transceiver converted from the transmitting state to the receiving state, the closing time delay corresponding to the transceiver is subtracted from the first difference, and a more accurate duration (i.e., a third difference) of the transceiver in the closed state is obtained.
In this embodiment of the present application, specifically, a first difference between a protection duration corresponding to a protection time slot and a conversion delay corresponding to a transceiver from a transmitting state to a receiving state may be determined, and a third difference between the first difference and a closing delay corresponding to the transceiver may be further determined, so that the third difference is determined as a duration of the transceiver in the closing state, so that when an uplink signal arrives, the transceiver may be controlled to be in an opening state in time, so as to receive the uplink signal.
In one design, as shown in fig. 8, in a transceiver control method provided in the embodiment of the present application, the method of determining the duration according to the first difference in step S301 may specifically include S601:
s601, determining a fourth difference value between the second difference value and the closing time delay corresponding to the transceiver, and determining the fourth difference value as the duration.
The second difference value is a difference value between the first difference value and the opening time delay corresponding to the transceiver.
Optionally, the corresponding closing time delay when the transceiver is from the open state to the closed state and the corresponding opening time delay when the transceiver is from the closed state to the open state may be determined, so that on the basis of determining the first difference between the protection time duration corresponding to the protection time slot and the conversion time delay corresponding to the transceiver converted from the transmitting state to the receiving state, the second difference is obtained by subtracting the opening time delay corresponding to the transceiver from the first difference, and further, the more accurate duration (i.e., the fourth difference) of the transceiver in the closed state is obtained by subtracting the closing time delay corresponding to the transceiver from the second difference.
The embodiment of the application provides a transceiver control method, when a transceiver of a base station is mutually converted between a transmitting state and a receiving state, the base station can switch off the transceiver in a protection time slot based on the proportion of a downlink and uplink conversion time slot corresponding to the transceiver in the process that the transceiver is converted from the transmitting state to the receiving state; and determining the duration of the transceiver in the off state based on at least one of the protection duration corresponding to the protection time slot, the transition time delay corresponding to the transceiver from the transmitting state to the receiving state, the off time delay corresponding to the transceiver and the on time delay corresponding to the transceiver, so as to start the transceiver to receive the uplink signal when the duration reaches the target duration. By the method, in the process that the transceiver is converted from the transmitting state to the receiving state, the transceiver is closed in the protection time slot, so that the condition that the downlink signals of the adjacent base stations are interfered after being overlapped is avoided, and the problem that the downlink signals of the adjacent base stations are interfered after being overlapped to cause saturation blocking of the transceiver is solved.
