detailed description

The technical solutions in the embodiments of the present invention will be clearly and completely described in the following with reference to the accompanying drawings.

In various embodiments of the present invention, the terminal acquires an interference-to-noise ratio of the component carrier; and determines a target component carrier according to a relationship between an interference-to-noise ratio of the component carrier and a preset threshold; wherein the target component carrier A component carrier capable of performing NAICS processing on the component carrier.

An embodiment of the present invention provides a signal determining method. Referring to FIG. 1, the method includes the following steps:

Step 101: Obtain an interference-to-noise ratio of a component carrier.

Specifically, the operation of acquiring the interference-to-noise ratio of the component carrier in step 101 can be implemented by the terminal.

The interference-to-noise ratio of the component carrier can be calculated by the terminal using the interference strength and noise of the component carrier.

Here, in actual application, there are a plurality of component carriers, so in step 101, the interference-to-noise ratio of each component carrier is determined.

Step 102: Determine a target component carrier according to a relationship between an interference-to-noise ratio of the component carrier and a preset threshold.

Wherein, the target component carrier is a component carrier in the component carrier capable of performing NAICS processing on the component carrier wave.

Specifically, in step 102, according to the relationship between the interference-to-noise ratio of the component carrier and the preset threshold, determining the operation of the target component carrier may be implemented by the terminal.

The preset threshold may be obtained by adjusting the terminal in combination with the simulation result and the actual measured value obtained in the actual application scenario.

When there are multiple component carriers, in step 102, the target component carrier is determined from each component carrier according to the relationship between the interference-to-noise ratio of each component carrier and a preset threshold.

The signal determining method provided by the embodiment of the present invention obtains the interference-to-noise ratio of the component carrier, and determines the target component carrier according to the relationship between the interference-to-noise ratio of the component carrier and the preset threshold; thus, the terminal, ie, the UE, can The processing capability selects the component carrier and sends it to the base station, and after the base station receives the component carrier sent by the UE and performs configuration, the UE can perform NAICS processing on the configured component carrier to implement carrier aggregation, which solves the processing capability in the prior art in the UE. When the finite is limited, the problem of eliminating the interference of the signals of the neighboring cells and enabling the UE to achieve a higher throughput cannot be implemented, and the base station is configured to configure the component carriers according to the limited processing capability of the UE, and the UE can perform carrier aggregation for each of the base station configurations. The component carrier performs NAICS processing to eliminate the interference of the adjacent cell signal, and the throughput of the UE can be improved.

An embodiment of the present invention provides a signal determining method. Referring to FIG. 2, the method includes the following steps:

Step 201: The terminal acquires a neighboring cell interference strength of the component carrier.

Specifically, the neighboring interference strength of the component carrier can be calculated by using formula (1):

I _i =RSRP _i -P _RSi i=1,2,3... (1);

Where I _i is the neighboring interference strength of the i-th component carrier, RSRP _i is the power value measured by the terminal for the received i-th component carrier reference signal, and P _RSi is the nominal power value of the corresponding reference signal .

That is, in step 201, the terminal acquires the neighbor interference strength of each component carrier.

Step 202: The terminal acquires thermal noise of the component carrier.

Specifically, the terminal may perform testing in advance to obtain thermal noise corresponding to the gain of different automatic gain control, and make a correspondence table and store the same, so that the terminal can use the corresponding relationship according to the gain of the automatic gain control required for each component carrier. The table performs a lookup table to obtain the thermal noise N _{0i of the} corresponding component carrier.

In step 202, the terminal acquires thermal noise of each component carrier.

Step 203: The terminal calculates a ratio of the neighboring interference strength of the component carrier to the thermal noise of the corresponding component carrier, to obtain an interference-to-noise ratio of the component carrier.

Specifically, the interference noise ratio ρ _{i of the} obtained component carrier can be calculated by using formula (2):

ρ _i =I _i /N _0i (2).

In step 203, the terminal separately calculates the ratio of the neighboring interference strength of each component carrier to the thermal noise of the corresponding component carrier, and obtains the interference-to-noise ratio of the corresponding component carrier.

Step 204: The terminal determines a magnitude relationship between an interference-to-noise ratio of the component carrier and a preset threshold.

Specifically, the terminal compares the interference-to-noise ratio of all component carriers obtained by the calculation with a preset threshold.

In step 204, the terminal determines a magnitude relationship between an interference-to-noise ratio of each component carrier and a preset threshold.

Step 205: If the interference-to-noise ratio of the component carrier is greater than a preset threshold, the terminal determines the number of component carriers whose interference-to-noise ratio of the component carrier is greater than a preset threshold, to obtain a first value.

Here, when the interference-to-noise ratio of the component carrier is less than a preset threshold, the terminal does not perform any processing.

Step 206: The terminal compares the relationship between the first value and M.

After the terminal 206 compares the relationship between the first value and the M, the terminal may select to perform step 207 or step 208. Specifically, if the first value is less than or equal to M, the step 207 is performed, if the first value is greater than the M option. Go to step 208.

Step 207: If the first value is less than or equal to M, the terminal acquires identification information of a component carrier whose interference-to-noise ratio of the component carrier is greater than a preset threshold, and sends the identifier information to the base station.

Where M is the number of component carriers that the terminal can simultaneously perform NAICS processing, and M is a positive integer.

Specifically, the terminal acquires a component carrier whose interference-to-noise ratio of the component carrier is greater than a preset threshold. For example, the first value of the component carrier that obtains the interference-to-noise ratio of the component carrier that is greater than the preset threshold is 3, and the identification information of the corresponding component carrier may be the number of the component carrier, for example, the interference-to-noise ratio of the component carrier is greater than The number of component carriers of the threshold may be 1, 3, 4; the number of component carriers capable of performing NAICS processing at the same time, that is, M is 5, because 3 is less than 5, that is, within a limited processing capability of the terminal, the terminal may All component carriers whose interference-to-noise ratio is greater than a preset threshold perform NAICS processing, so the terminal can acquire numbers 1, 3, and 4 of all component carriers whose interference-to-noise ratio is greater than a preset threshold, and send the component carriers number 1, 3, and 4 To the base station.

Step 208: If the first value is greater than M, the terminal sorts the component carriers whose interference-to-noise ratio of the component carrier is greater than a preset threshold according to the interference-to-noise ratio of the component carrier, and obtains the M component carriers before the sorting. Identify the information and send it to the base station.

For example, if the interference-to-noise ratio of the component carrier is greater than the preset threshold, the first value is 6, and the corresponding component carrier is numbered 1 to 6. The terminal can simultaneously perform the NAICS-processed component carrier. The number M is 5; because 6 is greater than 5, the terminal can sort the interference-to-noise ratio of the component carriers in order of largest to smallest, and obtain the order of the component carriers whose interference-to-noise ratio is greater than a preset threshold, such as component carriers. The order of the interference noise ratio from large to small is ρ ₁ >ρ ₂ >ρ ₃ >ρ ₄ >ρ ₅ >ρ ₆ , then the order of the component carriers is 1, 2, 3, 4, 5, 6; therefore, according to The processing capability of the terminal can obtain the numbers 1, 2, 3, 4, and 5 of the first five component carriers before the sequence to be sent to the base station. The manner in which the terminal sends the identification information of the component carrier to the base station may be implemented by the terminal transmitting the naics-Capability-List signaling in the UE-EUTRA-Capability to the base station.

It should be noted that the terminal may also sort the component carriers whose interference noise ratio of the component carrier is greater than a preset threshold according to the interference-to-noise ratio of the component carriers, and obtain the identification information of the M component carriers after the sequence and send the information. To the base station.

Step 209: The terminal receives the target component carrier sent by the base station, and performs NAICS processing on the target component carrier.

The target component carrier is obtained by the base station performing configuration processing on the component carrier corresponding to the identification information of the component carrier transmitted by the terminal.

Here, the identification information of the component carrier is pre-agreed between the base station and the terminal, so after the base station receives the identification information sent by the terminal, the base station can identify the identification information and determine the corresponding component. The carrier is configured to process the component carrier corresponding to the received identifier information, and the specific configuration processing manner may be: the base station sends the naics-Info information to the component carrier to be configured and processed by using the RadioResource ConfigDedicated signaling; The terminal receives the component carrier and identifies the naics-Info information in the component carrier, and performs NAICS processing on the component carrier having the naics-Info information. The specific NAICS processing process may refer to the related technical implementation method, which is not described in detail in this embodiment.

The signal determining method provided by the embodiment of the present invention obtains the interference-to-noise ratio of the component carrier, and determines the target component carrier according to the relationship between the interference-to-noise ratio of the component carrier and the preset threshold; thus, the UE selects according to its processing capability. After the component carrier is sent to the base station, and the base station receives the component carrier sent by the UE and performs configuration, the UE performs NAICS processing on the configured component carrier to implement carrier aggregation, which solves the problem that the UE cannot implement the phase cancellation when the UE has limited processing capability. The interference of the neighboring cell signal enables the UE to achieve higher throughput, and the base station configures the component carrier according to the limited processing capability of the UE, and the UE can perform NAICS processing on each component carrier configured by the base station for carrier aggregation, and eliminates The interference of the signals of the neighboring cells can improve the throughput of the UE.

An embodiment of the present invention provides a signal determining method. Referring to FIG. 3, the method includes the following steps:

Step 301: The terminal receives a control instruction sent by the base station.

The control instruction is used to instruct the terminal to acquire an interference-to-noise ratio of the component carrier.

Specifically, the base station informs the terminal that the current environment is a heterogeneous network environment with strong neighbor interference and needs to acquire an interference-to-noise ratio of the component carrier.

Step 302: The terminal acquires a neighboring cell interference strength of the component carrier.

Here, in actual application, there are multiple component carriers, so in step 302, the terminal acquires the neighbor interference strength of each component carrier.

Step 303: The terminal acquires thermal noise of the component carrier.

Here, the terminal acquires thermal noise of each component carrier.

Step 304: The terminal calculates a ratio of the neighboring interference strength of the component carrier to the thermal noise of the corresponding component carrier, to obtain an interference-to-noise ratio of the component carrier.

Here, the component carrier includes one primary component carrier and multiple secondary component carriers, wherein the primary component carrier and the secondary component carrier are determined by the base station. There is a relevant agreement between the terminal and the base station, according to which the terminal can identify the primary component carrier and the secondary component carrier. The interference-to-noise ratio of the component carrier calculated in the embodiment of the present invention includes an interference-to-noise ratio of the primary component carrier and an interference-to-noise ratio of the secondary component carrier. Of course, the method of calculating the interference-to-noise ratio of the primary component carrier and calculating the interference-to-noise ratio of the secondary component carrier is the same as the method of calculating the interference-to-noise ratio of the component carrier in steps 201 to 203.

Step 305: The terminal determines a relationship between an interference-to-noise ratio of the primary component carrier and a preset threshold.

Here, in the process of communication between the terminal and the base station, the primary component carrier is determined, and the identification information of the primary component carrier is pre-agreed between the terminal and the base station.

After the terminal determines the relationship between the interference-to-noise ratio of the primary component carrier and the preset threshold in step 305, the terminal may select to perform steps 306-307 or step 308; specifically, if the interference-to-noise ratio of the primary component carrier is greater than the preset The threshold selection performs steps 306-307, and if the interference-to-noise ratio of the primary component carrier is less than or equal to the preset threshold, step 308 is performed.

Step 306: If the interference-to-noise ratio of the primary component carrier is greater than a preset threshold, the terminal sends the identifier information of the primary component carrier to the base station.

Step 307: The terminal sorts the secondary component carriers according to the interference-to-noise ratio of the secondary component carrier according to the order of the largest component, and obtains the identification information of the M-1 secondary component carriers before the sequence and sends the identifier information to the base station.

Here, since the terminal has transmitted the identification information of the primary component carrier to the base station, the terminal may select the identification information of the M-1 secondary component carriers in the secondary component carrier and send the identifier information to the base station, so that the base station performs subsequent operations on the M component carriers. Processing, wherein the identifier information of the M-1 secondary component carriers is selected by the terminal, and the interference noise ratio of the terminal to the secondary component carrier is sorted in descending order, and the identification information of the M-1 secondary component carriers before the sorting is obtained. To achieve.

It should be noted that the terminal may also sort the component carriers whose interference-to-noise ratio of the component carrier is greater than a preset threshold according to the interference-to-noise ratio of the component carriers, and obtain the identification information of the M-1 component carriers after the sorting. And sent to the base station.

Step 308: If the interference-to-noise ratio of the primary component carrier is less than or equal to a preset threshold, the terminal root The secondary component carriers are sorted according to the interference-to-noise ratio of the secondary component carriers in order of largest to smallest, and the identification information of the M secondary component carriers before the sorting is obtained and sent to the base station.

Here, if the interference-to-noise ratio of the primary component carrier is less than or equal to the preset threshold, the terminal does not send the identification information of the primary component carrier to the base station, and the interference-to-noise ratio of the terminal to the secondary component carrier can be obtained according to the order from large to small. Sorting the secondary component carriers, so that the terminal selects the identification information of the M secondary component carriers according to the processing capability M, and then sends the identification information to the base station, so that the base station can correspond to the secondary component carrier corresponding to the identifier information of the received secondary component carrier. Follow up.

Step 309: The terminal receives the target component carrier sent by the base station, and performs NAICS processing on the target component carrier.

The base station performs configuration processing on the received primary component carrier and the M-1 secondary component carrier secondary component carrier, or the base station performs configuration processing on the received M secondary component carrier to obtain the target component carrier.

It should be noted that the description of the same steps or concepts in the other embodiments may be referred to in other embodiments, and details are not described herein again.
