Detailed Description
The following description of the embodiments of the present invention will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present invention, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the present invention without making any inventive effort, are intended to fall within the scope of the present invention.
Referring to fig. 1, a flow chart of an embodiment of a method for reducing in-device coexistence interference according to the present invention is provided.
The embodiment of the invention provides a method for reducing in-device coexistence interference, which can be applied to communication devices such as routers. The method comprises the steps S1 to S4, and specifically comprises the following steps:
s1, acquiring the current working frequency of the LTE module.
When the LTE module and the WIFI module of the equipment work simultaneously, the current working frequency of the LTE module is obtained.
S2, judging whether the current working frequency belongs to an FDD frequency band.
If the current operating frequency belongs to the FDD frequency band, step S3 is executed, otherwise, step S4 is executed.
S3, switching the working channel of the WIFI module to a high-priority channel based on a pre-constructed WIFI channel priority list when the current working frequency is judged to belong to the FDD frequency band; the channel priority of the WIFI module is divided according to the interference amount of the channel influenced by the LTE module.
In the pre-constructed WIFI channel priority list, the smaller the interference amount of the channel affected by the LTE module, the higher the priority, and the larger the interference amount of the channel affected by the LTE module, the lower the priority. The high priority channel is a channel with smaller interference amount affected by the LTE module, and can be any channel except the channel with the lowest priority, or can be the channel with the highest priority, or can be any channel with the priority higher than a certain level, and can be selected according to practical situations when the high priority channel is implemented, so that the beneficial effects of the invention are not affected.
When the current working frequency is judged to belong to the FDD frequency band, the LTE module is stated to work in the FDD frequency band, and the working channel of the WIFI module is switched to a high-priority channel according to a pre-constructed WIFI channel priority list, so that the influence of the LTE module on the WIFI module is reduced, and the coexistence interference of LTE and WIFI in equipment is reduced.
S4, when the current working frequency is judged not to belong to the FDD frequency band, controlling the WIFI module and the LTE module to be in the same working state; wherein the working state comprises a transmission data state and a reception data state.
When the current operating frequency is judged not to belong to the FDD frequency band, the LTE module is described as operating in the TDD frequency band, and at this time, the TX and the RX of the LTE module are time-division, and the TX and the RX do not operate simultaneously, i.e., the LTE module only operates in a data transmission state for a period of time, and then only operates in a data reception state for the next period of time. The TX and RX of the WIFI module are also time-division, and the TX and RX do not operate simultaneously, i.e. the WIFI module only operates in a transmission data state for a period of time, and then only operates in a reception data state for the next period of time.
When the current working frequency is judged not to belong to the FDD frequency band, the working states of the WIFI module and the LTE module are controlled so that the WIFI module and the LTE module are simultaneously in a data transmission state or a data receiving state, namely, when the LTE module works in the data transmission state, the WIFI also works in the data transmission state, when the LTE module works in the data receiving state, the WIFI module also works in the data receiving state, and therefore interference to the received data of the WIFI module is avoided when the LTE module transmits data, and interference to the received data of the LTE module is avoided when the WIFI module transmits data, and therefore the problem of mutual interference between the LTE and the WIFI in equipment is thoroughly solved.
On the basis of the above embodiment, referring to fig. 2, the WIFI channel priority list is pre-constructed by the following steps:
s10, testing the interference quantity of each channel of the WIFI module affected by the LTE module.
When the LTE module works, each channel of the WIFI module is tested for the interference quantity influenced by the LTE module. Alternatively, when the LTE module operates in a data transmission state with maximum power, the interference amount of each channel of the WIFI module affected by the LTE module may be tested.
And S20, according to the interference quantity received by each channel of the WIFI module, prioritizing and sequencing each channel of the WIFI module, thereby obtaining the WIFI channel priority list.
After the interference amount is obtained through testing, each channel of the WIFI module is prioritized according to the interference amount received by each channel of the WIFI module, and the priority is ranked from high to low, the smaller the interference amount of the channel influenced by the LTE module is, the higher the priority is, the larger the interference amount of the channel influenced by the LTE module is, the lower the priority is, and therefore the WIFI channel priority list is constructed and obtained.
Further, the testing the interference amount of each channel of the WIFI module affected by the LTE module specifically includes:
dividing the communication frequency supported by the LTE module into a plurality of specific frequency bands;
testing the interference quantity received by each channel of the WIFI module when the LTE module works in each specific frequency band;
and then, according to the interference amount received by each channel of the WIFI module, prioritizing and sequencing each channel of the WIFI module, thereby obtaining the WIFI channel priority list, which specifically includes:
for each specific frequency band, according to the interference quantity of the channel when the LTE module works in the specific frequency band, prioritizing and sequencing each channel of the WIFI module to obtain channel priority sequencing of each specific frequency band;
and constructing the WIFI channel priority list according to the channel priority sequence of each specific frequency band.
The communication frequency supported by the LTE module is divided into a plurality of specific frequency bands. And testing to obtain the interference quantity of each channel of the WIFI module when the LTE module works in each specific frequency band, namely, the interference quantity corresponding to each channel obtained by testing is the same as the number of the specific frequency bands. And then, aiming at each specific frequency band, according to the interference quantity of the channel when the LTE module works in the specific frequency band, prioritizing each channel of the WIFI module and sequencing the channels from high to low according to the priority, wherein the higher the priority is, the higher the interference quantity of the channel influenced by the LTE module is, and the lower the priority is, so that the channel priority sequencing of each specific frequency band is obtained. And finally, constructing a WIFI channel priority list according to the obtained channel priority order of each specific frequency band.
Alternatively, the interference influence matrix of the WIFI module in the data receiving state may be obtained by testing that the LTE module works in a specific frequency band and transmits data with maximum power, so as to obtain the interference amount suffered by each channel of the WIFI module when the LTE module works in each specific frequency band.
Still further, the switching the working channel of the WIFI module to the high priority channel based on the pre-constructed WIFI channel priority list specifically includes:
determining a high-priority channel of the WIFI module in a specific frequency band to which the current working frequency belongs according to the current working frequency and the pre-constructed WIFI channel priority list;
and switching the working channel of the WIFI module to the high-priority channel.
The method comprises the steps of firstly judging a specific frequency band to which a current working frequency belongs, determining a high-priority channel in the specific frequency band to which the current working frequency belongs according to a pre-constructed WIFI channel priority list, and then switching a working channel of a WIFI module to the high-priority channel.
As a preferred solution, on the basis of the foregoing embodiment, the controlling the WIFI module and the LTE module to be in the same working state specifically includes:
and the working states of the WIFI module and the LTE module are synchronously switched by controlling the working state switching time sequence of the WIFI module and the LTE module, so that the WIFI module and the LTE module are controlled to be in the same working state.
The switching between the receiving data state and the transmitting data state of the WIFI module and the LTE module is controlled according to the working state switching time sequence, namely the TX/RX switching time sequence, so that the working states of the WIFI module and the LTE module can be synchronously switched by controlling the working state switching time sequence of the WIFI module and the LTE module, and the WIFI module and the LTE module are controlled to be in the same working state.
The method for reducing the in-equipment coexistence interference provided by the embodiment of the invention comprises the steps of firstly obtaining the current working frequency of an LTE module; then judging whether the current working frequency belongs to an FDD frequency band or not; when the current working frequency is judged to belong to the FDD frequency band, switching the working channel of the WIFI module to a high-priority channel based on a pre-constructed WIFI channel priority list; the channel priority of the WIFI module is divided according to the interference amount of the channel influenced by the LTE module; when the current working frequency is judged not to belong to the FDD frequency band, the WIFI module and the LTE module are controlled to be in the same working state; wherein the working state comprises a transmission data state and a reception data state. When the LTE module and the WIFI module of the equipment work simultaneously, the working frequency band of the LTE module is judged whether to belong to the FDD frequency band, so that the working channel of the WIFI module is switched to a high-priority channel, or the WIFI module and the LTE module are controlled to be in the same working state, so that the interference of the LTE module to the WIFI module is minimized, the coexistence interference of LTE and WIFI in the equipment can be simply and effectively reduced while the communication quality is ensured, the SAW filter is not required to be additionally increased, the problem that the communication quality is influenced due to the fact that the insertion loss of the SAW filter is large in the prior art is solved, the internal structure of the equipment is not required to be adjusted, and the problem that the implementation difficulty is high due to the internal structure of the adjustment equipment in the prior art is solved.
