Description
Technical Field

Background
Currently, there are many cellular communication bands for mobile phones, and the mobile phones are used to establish communication with a base station through transmission of a Transmit (TX) signal and a Receive (RX) signal. The data is transmitted between the mobile phone terminal and the base station through the air interface wireless, the base station allocates Resource Blocks (RBs) for all mobile phone terminals in the cell, and the wireless transmission is carried and carried out through the RBs in the physical shared channel. And when the RB resources allocated by the base stations are different, the frequency spectrum distribution of the TX and the RX in data transmission is different, and the isolation degree of the TX and the RX is different. For some long term evolution (LTE, long Term Evolution) communication frequency bands adopting frequency division duplexing (FDD, frequency Division Duplex), transmission and reception are performed simultaneously, the interval between the transmission and reception working frequency bands is small, and the isolation between TX and RX is insufficient, so that when a mobile phone transmits TX signals, the reception of RX signals is affected, and the communication quality of users is deteriorated, and communication and network delay, even network drop, are generated. Typically, reducing the power of the TX transmit signal is employed to reduce the energy of the TX signal and thus reduce the effect of TX on RX.
However, although the method reduces the power of the TX transmitting signal, the uplink performance of the antenna is sacrificed to improve the receiving, and the problems of communication quality such as dropped call, unable incoming call, unable outgoing call, slow network speed and the like of weak signals easily occur; therefore, the existing method for improving the isolation of the receiving and transmitting signals has the technical problem of poor communication quality.

Detailed Description
The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application.
Example 1
An embodiment of the present application provides a configuration method, fig. 1 is a schematic flow diagram of an alternative configuration method provided by the embodiment of the present application, and referring to fig. 1, the configuration method may include:
s101: acquiring a communication state from a terminal;
at present, for a terminal registered on a channel of an FDD frequency Band, the situation that the communication quality of the terminal is poor due to insufficient isolation of uplink and downlink signals often occurs, taking LTE-Band13 as an example, fig. 2A is a schematic structural diagram of a receiving frequency Band of LTE-Band13, fig. 2B is a schematic structural diagram of a transmitting frequency Band of LTE-Band13, as shown in fig. 2A, the receiving frequency Band of B13 is 746-756MHz, as shown in fig. 2B, the transmitting frequency Band of B13 is 777-787MHz, the interval between the transmitting frequency Band and the receiving frequency Band is small, and the problem of insufficient isolation is easily generated.
As shown in fig. 2A and fig. 2B, one Resource Block (RB) is 12 subcarriers continuously in frequency, one subcarrier is 15KHz wide, and thus an RB width of 180KHz, an lte-Band13 transmission bandwidth and a reception bandwidth of 10MHz are obtained, and a 1MHz guard bandwidth is removed, corresponding to 50 RBs. The RB interval of the receiving frequency band is divided into RXA and RXB, the RB interval of the transmitting frequency band is divided into TXA and TXB, and it can be seen that the RXA and TXB intervals are farthest, in practical application, the requirements of isolation can be relatively met, when the base station distributes the RB of the terminal mobile phone, the RB is configured in RXA and TXA, the RXB and TXA, when the RB is configured in RXB and TXA, the requirements of isolation cannot be generally met, and allocation control on the RB configuration is needed.
In order to improve the communication quality of the terminal, the method is applied to a base station, and firstly, the base station acquires the communication state of the terminal.
Specifically, the communication state may be a report value, where the report value may be used to represent the communication state of the terminal, and in order to obtain the report value, first, the base station needs to send a message for inquiring the communication quality of the terminal to the terminal, so that the terminal returns a report value, where the report value may include two values, one of which is used to represent that the communication state of the terminal is an abnormal state, and the other value is used to represent that the communication state of the terminal is a normal state.
The abnormal state refers to that the network performance parameter of the terminal in communication does not meet the preset communication condition, and the normal state refers to that the network performance parameter of the terminal in communication meets the preset communication condition.
It should be noted that the network performance parameters may include delay, connection status of the network, signal strength, and the like, which are not limited in particular by the embodiments of the present application herein.
For example, when the delay is large and/or the network is in a disconnected state, the terminal is indicated to be in an abnormal state, and when the delay is small and the network is in a connected state, the terminal is indicated to be in a normal state.
In order to obtain the communication status of the terminal, in an alternative embodiment, S101 may include:
and when the channel registered by the terminal is a channel of the FDD frequency band and the terminal performs data transmission, acquiring the communication state from the terminal.
Specifically, only when the channel registered by the terminal is a channel in the FDD frequency band, that is, the terminal performs data communication by using FDD, at this time, there is insufficient isolation between uplink and downlink signals of the terminal, and only when the terminal performs communication, the poor communication environment affects the experience of the terminal user, so the base station obtains the communication state of the terminal only when the channel registered by the terminal is a channel in the FDD frequency band, and when the terminal is performing data transmission, and reconfigures resources for the terminal by monitoring the communication state of the terminal for the condition that the isolation is insufficient, thereby improving the communication state of the terminal.
S102: when the communication state is an abnormal state, the isolation between the uplink signal and the downlink signal of the terminal is obtained;
specifically, after knowing the communication state of the terminal, when the communication state of the terminal is in an abnormal state, in order to improve the communication quality of the terminal, the isolation between the uplink signal and the downlink signal of the terminal is obtained, so as to obtain the isolation between the uplink signal and the downlink signal of the terminal.
Here, it can be known whether the uplink and downlink signals of the terminal have a problem of insufficient isolation through the isolation, so that it can be known what causes cause the poor communication quality.
S103: when the isolation is smaller than a first preset threshold, respectively reconfiguring resource blocks for the uplink signal and the downlink signal to enlarge the isolation so that the communication state of the terminal is a normal state;
specifically, if the isolation is smaller than the first preset threshold, it indicates that there is an insufficient isolation between the uplink and downlink signals of the terminal, and if the isolation is greater than or equal to the first preset threshold, it indicates that the isolation between the uplink and downlink signals of the terminal is sufficient, so, only if the isolation is smaller than the first preset threshold, to solve the insufficient isolation, here, the resource blocks are allocated for the uplink signal and the downlink signal again to expand the isolation, so that the communication state of the terminal becomes a normal state, to eliminate the influence of the insufficient isolation on the communication quality of the terminal.
For the isolation degree being smaller than the first preset threshold, the base station needs to reconfigure the resource blocks for the uplink signal and the downlink signal to enlarge the isolation degree and ensure normal communication of the terminal, where the method for enlarging the isolation degree is multiple, and in an optional embodiment, S103 may include:
when the isolation is smaller than a first preset threshold and the upper limit of the uplink frequency band is larger than the upper limit of the downlink frequency band, configuring uplink signals on the last N resource blocks of the uplink frequency band, and configuring downlink signals on the first M resource blocks of the downlink frequency band;
when the isolation is smaller than a first preset threshold value and the upper limit value of the uplink frequency band is smaller than the upper limit value of the downlink frequency band, configuring uplink signals on the first N resource blocks and configuring downlink signals on the last M resource blocks;
specifically, firstly, for the FDD channel registered by the terminal, there are two cases, one is that the uplink frequency Band is higher than the downlink frequency Band, and the other is that the uplink frequency Band is lower than the downlink frequency Band, and generally, when the upper limit value of the uplink frequency Band is greater than the upper limit value of the downlink frequency Band, it is indicated that the uplink frequency Band is higher than the downlink frequency Band, for example, LTE-Band13, in order to ensure the isolation between the uplink signal and the downlink signal, the base station configures the uplink signal on the last N resource blocks of the uplink frequency Band, that is, configures the uplink signal on the resource block close to the maximum frequency value in the uplink frequency Band, where N is the number of resource blocks occupied by the uplink signal. And the base station configures the downlink signal on the first M resource blocks of the downlink signal, that is, configures the downlink signal on a resource block close to the minimum frequency value in the downlink frequency band, where M is the number of resource blocks occupied by the downlink signal. Therefore, the frequency interval between the resource blocks used by the uplink signal and the resource blocks used by the downlink signal is maximized, so that a larger isolation degree can be ensured, and the terminal can normally communicate.
When the upper limit value of the uplink frequency Band is smaller than the upper limit value of the downlink frequency Band, it is indicated that the uplink frequency Band is lower than the downlink frequency Band, for example, LTE-Band1, in order to ensure the isolation between the uplink signal and the downlink signal, the base station configures the uplink signal on the first N resource blocks of the uplink frequency Band, that is, configures the uplink signal on the resource block close to the minimum frequency value in the uplink frequency Band, where N is the number of resource blocks occupied by the uplink signal. And the base station configures the downlink signal on the last M resource blocks of the downlink signal, that is, configures the downlink signal on a resource block close to the maximum frequency value in the downlink frequency band, where M is the number of resource blocks occupied by the downlink signal. Therefore, the frequency interval between the resource blocks used by the uplink signal and the resource blocks used by the downlink signal is maximized, so that a larger isolation degree can be ensured, and the terminal can normally communicate.
In addition, in order to expand the isolation, in an alternative embodiment, S103 may include:
when the isolation is smaller than a first preset threshold value and the upper limit value of the uplink frequency band is larger than the upper limit value of the downlink frequency band, moving the resource blocks of the uplink signals towards the direction of increasing the frequency according to a preset first step length, moving the resource blocks of the downlink signals towards the direction of decreasing the frequency according to a preset first step length, reconfiguring the resource blocks of the uplink signals and the resource blocks of the downlink signals, and returning to execute to acquire the communication state from the terminal until the communication state of the terminal is in a normal state;
when the isolation is smaller than a first preset threshold and the upper limit of the uplink frequency band is smaller than the upper limit of the downlink frequency band, moving the resource blocks of the uplink signal towards the direction of decreasing frequency according to a preset first step length, moving the resource blocks of the downlink signal towards the direction of increasing frequency according to a preset first step length, so as to reconfigure the resource blocks of the uplink signal and the resource blocks of the downlink signal, and returning to execute the acquisition of the communication state from the terminal until the communication state of the terminal is in a normal state.
Specifically, for the case that the isolation is smaller than the first preset threshold, the upper limit of the uplink frequency band is larger than the upper limit of the downlink frequency band, which means that the uplink frequency band is higher than the downlink frequency band, in order to ensure the isolation between the uplink signal and the downlink signal, the base station moves the resource blocks of the uplink signal towards the direction of increasing the frequency according to the preset first step, for example, the first step is one resource block, the resource blocks used by the uplink signal are 5 th to 7 th resource blocks, wherein the numbers of the resource blocks are ordered according to the direction of increasing the frequency, after reconfiguration, the resource blocks used by the uplink signal are changed into 6 th to 8 th resource blocks, and similarly, the base station moves the resource blocks used by the downlink signal towards the direction of decreasing the frequency according to the preset first step, for example, the resource blocks used by the downlink signal are 9 th to 11 th resource blocks, and after reconfiguration, the resource blocks used by the uplink signal are changed into 8 th to 10 th resource blocks. And then returns to S101 again until the communication state of the terminal is normal. Therefore, the frequency interval between the resource blocks used by the uplink signal and the resource blocks used by the downlink signal is maximized, so that a larger isolation degree can be ensured, and the terminal can normally communicate.
In addition, if the upper limit value of the uplink frequency band is smaller than the upper limit value of the downlink frequency band, which means that the uplink frequency band is lower than the downlink frequency band, in order to ensure the isolation between the uplink signal and the downlink signal, the base station moves the resource blocks of the uplink signal towards the direction of decreasing frequency according to the preset first step, for example, the first step is one resource block, the resource blocks used by the uplink signal are 5 th to 7 th resource blocks, wherein the numbers of the resource blocks are ordered according to the increasing direction of the frequency, after reconfiguration, the resource blocks used by the uplink signal are 4 th to 6 th resource blocks, and similarly, the base station moves the resource blocks used by the downlink signal towards the direction of increasing frequency according to the preset first step, for example, the resource blocks used by the downlink signal are 9 th to 11 th resource blocks, after reconfiguration, the resource blocks used by the uplink signal are 10 th to 12 th resource blocks, and then returns to execute S101 again until the communication state of the terminal is normal. Therefore, the frequency interval between the resource blocks used by the uplink signal and the resource blocks used by the downlink signal is maximized, so that a larger isolation degree can be ensured, and the terminal can normally communicate.
In addition, in order to better configure the resource blocks used by the terminal, in an alternative embodiment, S103 may include:
when the isolation is smaller than a first preset threshold value and the service cell of the terminal meets preset configurable conditions, respectively reconfiguring resource blocks for uplink signals and downlink signals so as to enlarge the isolation and enable the communication state of the terminal to be a normal state;
that is, when the isolation is smaller than the first preset threshold, it is required to determine whether the service size of the terminal satisfies the preset configurable condition, only when the service cell satisfies the preset configurable condition, which means that the base station may reconfigure the resource block for the terminal, and when the service cell does not satisfy the preset configurable condition, which means that the base station does not have available resources to reconfigure the resource block for the terminal, so here, only when the service cell satisfies the preset configurable condition, the base station reconfigures the resource block for the uplink signal and the downlink signal, respectively, where the reconfiguration method may employ the method of one or more embodiments of the present application.
In addition, in order to improve the communication quality of the terminal, in an alternative embodiment, S103 may include:
and when the isolation degree is smaller than a first preset threshold value and the service cell of the terminal does not meet preset configurable conditions, reducing the transmitting power of the uplink signal according to a preset second step length, and returning to execute the communication state of the lake area from the terminal until the communication state of the terminal is a normal state.
Specifically, when the serving cell does not meet the preset configurable condition, that is, the base station has no available resources to reconfigure the resource blocks for the uplink signal and the downlink signal, the base station reduces the transmission power of the uplink signal according to the preset second compensation, so as to reduce the influence of the uplink signal on the downlink signal.
In an optional embodiment, the serving cell of the terminal meets a preset configurable condition, including:
when the number of users in the service cell is smaller than a second preset threshold value and/or the communication data volume in the service cell is smaller than a third preset threshold value, determining that the service cell of the terminal meets preset configurable conditions;
that is, when the number of users smaller than the server is smaller and/or the communication data amount of the serving cell is smaller, it is indicated that the base station also has available resources to reconfigure the resource blocks for the uplink signal and the downlink signal, so that the serving cell of the terminal is considered to satisfy the preset configurable condition at this time.
The service cell of the terminal does not meet preset configurable conditions, which comprises the following steps:
and when the number of the users of the service cell is larger than or equal to the second preset threshold value and the communication data volume of the service cell is larger than or equal to the third preset threshold value, determining that the service cell of the terminal does not meet preset configurable conditions.
Specifically, when the number of users smaller than the server is large and the communication data volume of the serving cell is large, it is indicated that the base station has no available resources to reconfigure the resource blocks for the uplink signal and the downlink signal, so that the serving cell of the terminal is considered to not meet the preset configurable condition at this time.
In order to reduce the effect of the upstream signal on the downstream signal, in an alternative embodiment, the method further comprises:
and when the isolation is greater than or equal to a first preset threshold, reducing the transmitting power of the uplink signal according to a preset second step length, and returning to execute the acquisition of the communication state from the terminal until the communication state of the terminal is a normal state.
For the situation that the isolation is greater than or equal to the first preset threshold, at this time, the isolation between the resource block used by the uplink signal and the resource block used by the downlink signal of the terminal is sufficient, but the terminal still has the problem of poor communication quality, at this time, the base station reduces the transmitting power of the uplink signal according to the second step length, and returns to S101 until the communication state of the terminal is a normal state.
The configuration methods described in one or more of the above embodiments are described below by way of example.
Fig. 3 is a flowchart of an example of an alternative configuration method provided in an embodiment of the present application, and as shown in fig. 3, taking LTE-Band13 as an example, the configuration method may include:
s301: the base station judges whether the terminal is registered to LTE-Band13; if yes, executing S303; if not, acquiring the communication state of the terminal, and executing S302;
specifically, first, the base station detects whether the end user registers to a problem Band channel (this is exemplified by LTE-Band 13) with insufficient isolation, and if not, S303 is executed; if yes, the communication state of the terminal is obtained, and S302 is executed;
s302: the base station judges whether the terminal needs to transmit downlink data, if not, the base station executes S303; if yes, executing S304;
specifically, the base station determines that the terminal user does not need to perform a large amount of data transmission, does not need to perform regulation and control, and executes normal work; otherwise, executing S304;
s303: normally works;
s304: the base station judges whether the communication transmission can be met according to the communication report value of the terminal; if yes, executing S303; if not, executing S305;
specifically, the base station judges whether the downlink communication of the terminal user is delayed or dropped according to the communication report value of the terminal, if not, the user communication is normal and the user works normally; if there is delay and/or network drop, judging that the user may have isolation problem in the frequency band, resulting in delay of the downlink network of the user, and executing S305;
s305: the base station judges whether the interval where the uplink and downlink resource blocks are located is a TXB and RXA area with larger isolation, if yes, S307 is executed; if not, executing S306;
specifically, if the section where the resource block used by the uplink signal is located is TXB and the section where the resource block used by the downlink signal is located is RXA, it is indicated that the communication problem cannot be improved in the RB section with the maximum relative isolation, and S307 is executed; if not, executing S306 in the area where the isolation of the current RB resource block is relatively insufficient;
s306: the base station judges whether the uplink and downlink resource blocks can be reconfigured; if so, S308 is performed; if not, executing S307;
in practical application, whether the resource block can be reconfigured depends on the cell environment, the amount of terminal users, the amount of terminal communication data, etc., and the base station is required to determine, if not, S307 is executed; if yes, executing S308;
s307: the base station reduces the transmission power of TX; s304 is executed;
specifically, when the uplink and downlink signals are in the RB interval with the maximum relative isolation, the communication problem cannot be improved, and even if the RB resources are allocated, the effect is not obvious, so that the base station reduces the TX transmission power, reduces the TX energy transmission, further reduces the influence on the RX, and the base station determines whether the reported value of the user meets the communication requirement at this time, that is, returns to S304.
If the current resource block cannot be reconfigured, the RX receive signal needs to be optimized in a manner that reduces the TX transmit power.
S308: the base station configures the uplink RB to the high position and configures the downlink RB to the low position.
Specifically, the base station configures the RB used by the uplink signal to the RB of the high frequency band, and configures the RB used by the downlink signal to the RB of the low frequency band, so that the isolation between TX and RX is gradually increased, and then returns to S304, and determines whether the current isolation meets the communication transmission through the report value.
That is, the above example loops when the communication transmission is not satisfied, sequentially judges the condition of the RB resource blocks, gradually adopts the resource blocks with reduced TX transmit power and the reallocated interval being distant for improvement and optimization of communication until the communication transmission is satisfied, and works normally.
