The resource allocation method proposed in the present disclosure can be executed by a terminal or by a chip or processor of the terminal.

[0041] The interference resource determination method proposed in this application will be described in detail below with reference to the accompanying drawings.

[0042] When the resource block distribution of the reference signal is continuous, the location of the interference resource is also continuous, that is, the interference area is an area that is relatively concentrated. Therefore, according to this feature, the full bandwidth is segmented, the power value of the endpoint resource block is calculated, and the location of the interference resource is determined based on the power value of the resource block of each endpoint. This can achieve the goal of not using the full bandwidth to calculate the power value, thereby reducing power consumption, and more quickly determining the interference resource to extend the standby time of the terminal product without adding additional hardware resources.

[0043] Figure 1 A method flow chart of a method for determining interference resources proposed in an embodiment of the present disclosure is shown in FIG. Figure 1 As shown, the method is executed by a terminal, and the method includes the following steps:

[0044] Step 101: When the type of the reference signal is a target type, the full bandwidth is divided into a plurality of segments, and the power value of the resource block corresponding to the first endpoint in each segment is determined respectively.

[0045] In some embodiments, the target type may be type 1, where type 1 is, for example, a type in which resource blocks (RBs) are distributed continuously. It is understood that the reference signal types are divided into continuous and discontinuous types. In the case of a continuous reference signal type, the signal received by the terminal at the full bandwidth is a continuous signal, and in the case of a discontinuous reference signal type, the signal received by the terminal at the full bandwidth is a discrete signal.

[0046] In some embodiments, the type of the reference signal is configured by the base station according to a register, that is, the base station can send a continuous signal or a discrete signal to the terminal based on the configuration. After the terminal receives the reference signal sent by the base station, it determines the type of the reference signal.

[0047] For example, when the reference signal type is type1, the terminal starts this solution. When the type is type1, the RB distribution is continuous, and when the reference signal type is type2, the resource distribution is discontinuous, which is not conducive to the use of this solution. Therefore, it is recommended to start it when type1.

[0048] In some embodiments, the full bandwidth is, for example, 273 RB.

[0049] In some embodiments, dividing the full bandwidth into multiple segments and determining the power value of the resource block corresponding to the first endpoint in each segment respectively can be performed by dividing the full bandwidth into multiple segments in a step-by-step increasing order, that is, the number of RBs in each segment increases step by step, and calculating the power value of the endpoint resource block in each segment.

[0050] In some embodiments, the full bandwidth is divided into multiple segments, and the power value of the resource block corresponding to the first endpoint in each segment is determined separately, which can be that the full bandwidth is evenly divided, the number of RBs in each segment is equal, and the power value of the endpoint resource block in each segment is calculated. The number of evenly divided segments can be determined according to the power value, that is, when the power value of the endpoint does not meet the pre-set condition, the even division continues until the condition is met.

[0051] In some embodiments, dividing the full bandwidth into multiple segments and determining the power value of the resource block corresponding to the first endpoint in each segment can be performed by first dividing the full bandwidth into segments in increasing order and then equally dividing the segments to obtain multiple segments, and further determining the power value of the resource block corresponding to each first endpoint in each segment.

[0052] In some embodiments, the full bandwidth is divided into multiple segments, and the power value of the resource block corresponding to the first endpoint in each segment is determined respectively. The full bandwidth can be segmented by using a binary search method. The power values ​​of the three endpoints are calculated for the first time, which are the front, middle and back points. At this time, the full bandwidth is divided into 2 segments; the middle points of the two segments are calculated for the second time. At this time, the full bandwidth is divided into 4 segments; the middle points of the 4 segments are calculated for the third time. At this time, the full bandwidth is divided into 8 segments.

[0053] In some embodiments, when the reference signal type is a target type, the full bandwidth is segmented and the power value of the resource block corresponding to each endpoint is calculated, so as to reduce the number of times the power value is calculated and achieve the purpose of reducing power consumption.

[0054] Step 102: Determine the location of the interference resource based on the power value of the resource block corresponding to the first endpoint.

[0055] In some embodiments, determining the location of the interference resource based on the power value of the resource block corresponding to the first endpoint can be done by calculating the power value of the resource block corresponding to each first endpoint among the multiple resource blocks corresponding to the first endpoints obtained after the first segmentation, and determining the resource block whose power value meets a pre-set power value threshold as the location of the interference resource.

[0056] In some embodiments, determining the location of the interference resource based on the power value of the resource block corresponding to the first endpoint may be determining the resource block corresponding to the first endpoint that meets the power value condition as the location of the interference resource after segmenting the full bandwidth multiple times.

[0057] In some embodiments, the position of the interference resource is determined based on the power value of the resource block corresponding to the first endpoint. After the full bandwidth is segmented for the first time, the resource block corresponding to the first endpoint that meets the power value condition is determined as the initial position of the interference resource, and then the power value of the resource blocks within a certain range around the endpoint is calculated, and the resource block that meets the power value condition is determined as the end position of the interference resource.

[0058] In some embodiments, based on the power value of the resource block corresponding to the first endpoint, determining the location of the interference resource can be performed by dividing the full bandwidth into multiple segments as in step 101, calculating the power value of each endpoint, and determining the resource block corresponding to the endpoint that meets the power value condition as the location of the interference resource.

[0059] In the above embodiment, by segmenting the full bandwidth and calculating the power value of the resource block of the endpoint in each segment, the location of the interference resource is determined according to the power value, thereby reducing power consumption without adding additional hardware resources and enabling the terminal product to have a longer standby time.

[0060] Figure 2 A schematic diagram of a process for determining the location of interference resources proposed in an embodiment of the present disclosure. Figure 1 The embodiment shown, Figure 2 Step 102 is further defined as follows: Figure 2 As shown, the method comprises the following steps:

[0061] Step 201: Determine a resource block that meets a preset condition among power values ​​of resource blocks corresponding to a first endpoint as a first resource block.

[0062] In some embodiments, the preset condition may be that the power value is greater than a power threshold, and the power threshold may be a pre-set value, and its specific value may be obtained based on historical experience or experiments, which is not limited by the present disclosure.

[0063] In some embodiments, the resource blocks satisfying the preset condition are interference resources, that is, the first resource block is the location of the interference resource.

[0064] In some embodiments, the first resource block may be one or more, which is not limited by the present disclosure.

[0065] In some embodiments, dividing the full bandwidth into multiple segments may be performed by using a binary division method, such as Fig. 7A As shown in the schematic diagram, each segment is divided into two segments each time, and the power value of the resource block corresponding to the endpoint of each segment is calculated.

[0066] In some embodiments, a resource block whose power value meets a preset condition among the resource blocks corresponding to the first endpoint is determined as a first resource block. The resource block whose power value is greater than a power threshold among the resource blocks of each endpoint after full bandwidth segmentation may be determined as the first resource block. The first resource block may be determined as an interference resource.

[0067] For example, Fig. 7AAs shown in the schematic diagram, the first calculation is performed on three endpoints, which are the resource blocks at the front, middle and back points. At this time, the full bandwidth is divided into 2 segments. If the power values ​​of the resource blocks at these three endpoints are not greater than the power threshold, the middle endpoints of the two segments are calculated for the second time. At this time, the full bandwidth is divided into 4 segments. If there is a resource block with a power value greater than the power threshold, the resource block is determined to be the first resource block. If the power values ​​of the two endpoints are not greater than the power threshold, the third segment calculation is continued to calculate the power value of the resource block at the middle point of the 4 segments. At this time, the full bandwidth is divided into 8 segments, and it is continued to be determined whether there is a resource block greater than the power threshold, and the resource block is determined to be the first resource block.

[0068] In some embodiments, the first resource block may be one or more, which is not limited by the present disclosure.

[0069] For example, Figure 7B As shown in the schematic diagram, during the third segment calculation, the power values ​​of the resource blocks corresponding to the second and fourth endpoints are greater than the power threshold, and the resource blocks corresponding to these two points are determined as the locations of the interference resources.

[0070] Step 202: divide the first segment where the first resource block is located into a plurality of second segments, and determine the second resource block based on the power value of the resource block corresponding to the second endpoint in each second segment.

[0071] In some embodiments, the segment between the first resource block and the second resource block is the location of the interfering resource.

[0072] In some embodiments, dividing the first segment where the first resource block is located into multiple second segments can be to determine the segment with the first resource block as the midpoint as the first segment, perform segment calculation on the first segment, and obtain the power value of the resource block corresponding to the endpoint of each second segment.

[0073] In some embodiments, dividing the first segment where the first resource block is located into multiple second segments can be to take the left half or right half area of ​​the full bandwidth where the first resource block is located as the first segment, and continue to perform segment calculation on the first segment to obtain the power value of the resource block corresponding to the endpoint of each second segment.

[0074] In some embodiments, when there are multiple first resource blocks, dividing the first segment where the first resource block is located into multiple second segments can be to take the area composed of segments with each first resource block as the midpoint as the first segment, and continue to perform binary segmentation or step-by-step segmentation on the first segment to obtain the power value of the resource block corresponding to the endpoint of each second segment.

[0075] In some embodiments, Figure 7BAs shown in the schematic diagram, the power value of the resource block in the shaded part meets the preset conditions, indicating that the interference area is concentrated in the area of ​​0 to n / 2 on the left. The left half area is further segmented to find the boundary position of the interference resource. The left half area can be further segmented by an equal division method, divided into a preset value of second segments, or by a step-by-step increasing segmentation method, divided into second segments with different numbers of resource blocks, or by a binary division method, each segment is divided into two each time to obtain multiple second segments.

[0076] In some embodiments, based on the power value of the resource block corresponding to the second endpoint in each second segment, determining the second resource block can be by calculating the power value of the resource block corresponding to the second endpoint of each second segment after the above segmentation, and determining the resource block whose power value meets the preset conditions as the second resource block.

[0077] In some embodiments, based on the power value of the resource block corresponding to the second endpoint, determining the second resource block may be determining the resource block of the neighboring endpoint (the endpoint does not meet the preset condition) of the resource block whose power value meets the preset condition as the second resource block. It can be understood that determining the neighboring resource block that does not meet the preset condition as the second resource block can make the determined position of the interference resource slightly larger than the actual position, thereby avoiding missing the interference resource.

[0078] For example, Figure 7B As shown in the schematic diagram, the power value of the left half area is further calculated by binary division, and the power value of the resource block in the right half area does not need to be calculated again, so as to achieve the purpose of reducing the number of operations and thus reduce power consumption.

[0079] In the above embodiment, the resource block that meets the preset conditions among the power values ​​of the resource blocks of each endpoint after segmentation is determined as the approximate location of the interference resource, and the power value is further calculated in segments based on the segment where the resource block is located, and then the location of the interference resource is determined based on the power value of each endpoint, thereby achieving the purpose of reducing the number of calculations and thus reducing power consumption.

[0080] Figure 3 A schematic diagram of a process for determining a second resource block according to an embodiment of the present disclosure. Figure 1-Figure 2 The embodiment shown, Figure 3 right Figure 2 Step 202 in the further definition is as follows: Figure 3 As shown, the following steps are also included.

[0081] Step 301: divide the first segment into two n second segments, and determining a power value of a resource block corresponding to a second endpoint in each second segment.

[0082] In some embodiments, n is successively integers greater than 0, that is, n is successively 1, 2, 3, 4, ...

[0083] In some embodiments, the first segment may be a region of the first resource block corresponding to half of the full bandwidth.

[0084] In some embodiments, the first segment is divided into two n The second segmentation can be to divide the first segment into 2 segments, 4 segments, 8 segments, 16 segments, etc., that is, n is 1, 2, 3, 4, etc. It can be understood that each segmentation is performed by binary division. For example, Fig. 7A As shown in the schematic diagram, the middle point of the left half area is taken, and then the middle point and the two end points are used as boundaries, and the middle point is taken again.

[0085] In some embodiments, determining the power value of the resource block corresponding to the second endpoint in each second segment can be to determine the power value of the resource block corresponding to the midpoint of the first segment after the first segmentation, and then determine the power value of the resource block corresponding to the endpoint other than the first endpoint (i.e., the second endpoint) among the four endpoints of the second segments obtained after the second segmentation. If the power value of the resource block still does not meet the preset conditions, continue segmenting, and determine the power value of the resource block corresponding to the endpoint other than the first endpoint (i.e., the second endpoint) among the eight endpoints of the second segments obtained after the third segmentation, until a resource block with a power value that meets the preset conditions appears.

[0086] Step 302: Determine a resource block that meets a preset condition among the power values ​​of the resource blocks corresponding to the second endpoint as a third resource block.

[0087] In some embodiments, according to the process of segmenting and determining the power value in step 301, when the power value of the resource block corresponding to one or more second endpoints meets the preset condition, the resource block corresponding to the second endpoint is determined as the third resource block. The third resource block can be one or more, which is not limited by the present disclosure.

[0088] In some embodiments, if the power value of the resource block corresponding to the midpoint of the first segment satisfies a preset condition after the first segment is segmented once in step 301, the resource block corresponding to the midpoint (ie, the second endpoint) is determined as the third resource block.

[0089] In some embodiments, if, after segmenting the first segment twice in step 302, an endpoint satisfying a preset condition appears among the second endpoints of the four second segments obtained (endpoints other than the first endpoint), the resource block corresponding to the second endpoint is determined as the third resource block.

[0090] In some embodiments, after the first segment is segmented n times in step 302, the obtained 2 n If an endpoint that meets a preset condition appears among the second endpoints of the second segments (endpoints other than the first endpoint), the resource block corresponding to the second endpoint is determined as the third resource block.

[0091] Step 303: divide the third segment where the third resource block is located into multiple fourth segments until the fourth segment corresponds to two resource blocks, and determine the resource block corresponding to the third endpoint whose power value meets the preset condition as the second resource block.

[0092] In some embodiments, the third segment where the third resource block is located may be the area of ​​the third resource block corresponding to the left half or the right half of the first segment. For example, taking the midpoint of the first segment as the dividing line, if the third resource block is to the left of the midpoint, the left area is the third segment; or if the third resource block is to the right of the midpoint, the right area is the third segment.

[0093] In some embodiments, the third segment can be divided into multiple fourth segments by segmenting in the segmentation manner of step 301, determining the power value of the resource block corresponding to the endpoint of each segment, determining the resource block whose power value meets the preset conditions as the selected resource block, and continuing to segment the segment where the selected resource block is located until the fourth segment finally obtained cannot be segmented any further (that is, the fourth segment corresponds to two resource blocks), and determining the resource block whose power value corresponds to the third endpoint of the multiple fourth segments meets the preset conditions as the second resource block.

[0094] In some embodiments, the second resource block may be one or more, which is not limited by the present disclosure.

[0095] In some embodiments, dividing the third segment into multiple fourth segments can be dividing the third segment into two fourth segments, determining the power value of the resource block corresponding to the third endpoint in each fourth segment, and if there is no resource block that meets the preset conditions, continuing to divide into four fourth segments, determining the power value of the resource block corresponding to the third endpoint in each fourth segment, until a resource block that meets the preset conditions appears, and continuing to segment the segment where the resource block is located according to the above-mentioned segmentation method, and continuously finding the edge of the interference resource, until all the resource blocks in a certain segment are calculated, and obtaining one or more second resource blocks that meet the preset conditions, the area or segment composed of the first resource block and the second resource block is the area or segment of the interference resource.

[0096] In the above embodiment, by using binary division to calculate the power value of the full bandwidth, and continuing to use binary division to segment the segments where the resource blocks that meet the preset conditions are located, the number of power value calculations can be reduced to reduce power consumption and achieve a longer standby time for the terminal product.

[0097] Figure 4 The following is a flow chart of the interference resource determination method proposed in the embodiment of the present disclosure. Figure 1-Figure 3 The embodiment shown, as Figure 4 As shown, the method also includes the following steps.

[0098] Step 401, obtaining current channel parameters.

[0099] In some embodiments, the current channel parameter may be a parameter of a CSI channel state, such as a delay spread (Delay Spread), a signal to noise ratio (SNR), a Doppler (Doppler) and other related parameters.

[0100] In some embodiments, the channel parameters can be used to determine changes in the communication channel, for example, by comparing the current channel parameters with the historical channel parameters to determine whether a scene change occurs in the terminal. For example, when the user holding the terminal is working in an office, lying on a sofa, or walking, the change in the communication channel will not be obvious or sudden, and whether there is an obvious change can be determined by the CSI channel status.

[0101] Step 402: Determine a change value based on current channel parameters and historical channel parameters.

[0102] In some embodiments, the change value is determined based on the current channel parameters and the historical channel parameters, and the change value may be obtained by subtracting the delay spread value in the current channel parameters from the delay spread value in the historical channel parameters.

[0103] In some embodiments, the change value is determined based on the current channel parameters and the historical channel parameters, and the change value may be obtained by subtracting the signal-to-noise ratio value in the current channel parameters from the signal-to-noise ratio value in the historical channel parameters.

[0104] In some embodiments, the change value is determined based on the current channel parameters and the historical channel parameters, and the change value may be obtained by subtracting the Doppler value in the current channel parameters from the Doppler value in the historical channel parameters.

[0105] In some embodiments, the change value is determined based on the current channel parameters and the historical channel parameters, and the change value may be obtained by subtracting the values ​​of other parameters in the current channel parameters from the values ​​of corresponding parameters in the historical channel parameters.

[0106] In some embodiments, when the channel state changes, that is, the change value between the current channel parameter and the historical channel parameter exceeds a certain threshold, it means that the channel state has changed significantly and is not suitable for referring to the location of the historical interference resource.

[0107] Step 403: When the change value is lower than a preset threshold, the location of the current interfering resource is determined based on the location of the historical interfering resource.

[0108] In some embodiments, when the channel state changes little, that is, the change value between the current channel parameters and the historical channel parameters is lower than a preset threshold, it indicates that the channel state is relatively stable, and the location of the current interference resource can be determined by referring to the location of the historical interference resource, thereby reducing the number of power calculations and further reducing power consumption.

[0109] In some embodiments, based on the location of historical interference resources, determining the location of current interference resources may be by using the location of the previous historical interference resources to determine the location of the current interference resources, or by using the locations of the previous two historical interference resources to determine the location of the current interference resources, or by using the locations of the previous three historical interference resources, which is not limited by the present disclosure.

[0110] In some embodiments, based on the location of historical interference resources, determining the location of current interference resources can be by calculating power values ​​using boundary points of historical interference resources, and then segmenting the full bandwidth based on the power values. For example, boundary points that meet preset conditions are used as reference points for segmentation, and the boundary points are segmented corresponding to half of the full bandwidth. Segmentation can be performed using an equal division method, a step-by-step increase method, or a binary division method. The power value of each endpoint is calculated, and a judgment is made based on the power value and the preset conditions, gradually approaching the boundary of the interference resource, and then determining the location of the current interference resource.

[0111] In the above embodiment, by judging the channel state, when the change value of the channel state is lower than the preset threshold, the location of the current interference resource can be determined based on the location of the historical interference resource, so as to avoid the need to traverse and calculate the power value from the beginning, thereby achieving the purpose of reducing the amount of calculation, and improving the speed of determining the interference resource, further reducing power consumption.

[0112] Figure 5 A schematic diagram of a process for determining the location of a current interfering resource proposed in an embodiment of the present disclosure. Figure 1-Figure 4 The embodiment shown, Figure 5 right Figure 4 Step 402 in the further definition is as follows: Figure 5 As shown, the following steps are also included.

[0113] Step 501: determine power values ​​of at least two fourth resource blocks corresponding to the boundary of the historical interference resource.

[0114] In some embodiments, determining the power values ​​of at least two fourth resource blocks corresponding to the boundary of the historical interference resource may be determining the power values ​​of two fourth resource blocks corresponding to two boundary endpoints of the previously determined historical interference resource using the position of the previously determined historical interference resource.

[0115] In some embodiments, determining the power values ​​of at least two fourth resource blocks may be determining the power values ​​of four fourth resource blocks corresponding to four boundary endpoints of the historical interference resources determined twice before using the positions of the historical interference resources determined twice before.

[0116] In some embodiments, determining the power values ​​of at least two fourth resource blocks may be determining the power values ​​of eight fourth resource blocks corresponding to the three previous historical interference resources using the positions of the three previous historical interference resources.

[0117] In some embodiments, the power value of the fourth resource block corresponding to the boundary endpoint of the used historical interference resources is determined according to the number of used historical interference resources.

[0118] Step 502: When there is a resource block satisfying a preset condition among the power values ​​of at least two fourth resource blocks, divide the segment between the fifth resource block and the boundary resource block of the full bandwidth into a plurality of fifth segments.

[0119] In the present disclosure, the fifth resource block is a fourth resource block that meets a preset condition.

[0120] In some embodiments, when there is a resource block that meets the preset conditions among the power values ​​of at least two fourth resource blocks, that is, the power value of the fifth resource block meets the preset conditions, then the fifth resource block is an interference resource, and the segmentation between the fifth resource block and the two boundary resource blocks of the full bandwidth is used as the basis for segmentation to divide it into multiple fifth segments.

[0121] In some embodiments, dividing the segment between the fifth resource block and the full-bandwidth boundary resource block into multiple fifth segments can be that when there are two fifth resource blocks whose power values ​​meet a preset condition, the segment between the full-bandwidth left boundary resource block and its adjacent fifth resource block is divided into multiple fifth segments, and the segment between the full-bandwidth right boundary resource block and its adjacent fifth resource block is divided into multiple fifth segments, thereby realizing segmented power value calculation with the interference resource block as the boundary and the bandwidth boundary as the edge, reducing the number of calculations and reducing power consumption.

[0122] In some embodiments, dividing the segment between the fifth resource block and the boundary resource block of the full bandwidth into a plurality of fifth segments may be performed as follows: Figure 3 The segmentation is performed using the segmentation method shown in step 301, which will not be described in detail here.

[0123] For example, Figure 7C The schematic diagram shown is based on the boundary resource blocks of the previous historical interference resources. If the power values ​​of the two boundary resource blocks are calculated to be greater than the preset power values, there is interference. The two boundary resource blocks are used as boundaries and the bandwidth boundary is used as the edge for dichotomy, and the shaded square is the boundary of the interference position.

[0124] Step 503: Determine the location of the current interfering resource based on the power value of the resource block corresponding to the fourth endpoint in each fifth segment.

[0125] In some embodiments, based on the power value of the resource block corresponding to the fourth endpoint in each fifth segment, determining the position of the current interfering resource includes: determining the resource block that meets the preset condition among the power values ​​of the resource blocks corresponding to the fourth endpoint as the sixth resource block; dividing the segment between the sixth resource block and the first boundary resource block into two n The sixth segments are respectively determined, and the power values ​​of the resource blocks corresponding to the fifth endpoints in each sixth segment are determined; based on the power values ​​of the resource blocks corresponding to the fifth endpoints, the seventh resource block is determined, the segment between the sixth resource block and the seventh resource block is the location of the current interference resource, and the power value of the seventh resource block meets the preset conditions.

[0126] In some embodiments, the first boundary resource block is a boundary resource block adjacent to a location of the sixth resource block in the full bandwidth.

[0127] In some embodiments, based on the power value of the resource block corresponding to the fourth endpoint in each third segment, the position of the current interfering resource can be determined as shown in Figure 2 and Figure 3 The steps shown in the illustrated embodiment will not be repeated here.

[0128] In some embodiments, for the resource block corresponding to the fourth endpoint in each third segment, if the preset conditions are not met, segmentation needs to continue, that is, the value of n is increased by 1 until the power value of the resource block corresponding to the fourth endpoint meets the preset conditions, and the basis for the next round of segmentation is determined, that is, the segmentation between the sixth resource block corresponding to the fourth endpoint that meets the preset conditions and the first boundary resource block is used as the basis, and the above-mentioned segmentation method is used for segmentation. After continuously approaching the boundary, the seventh resource block that finally meets the preset conditions is obtained. Then the sixth resource block and the seventh resource block are the locations of the current interference resources.

[0129] In the above embodiment, the full bandwidth is segmented based on historical interference resources, and the binary method is used to continue to calculate the power value of each segment to determine the location of the current interference resource, thereby reducing the amount of calculation, improving the calculation efficiency, achieving the purpose of reducing power consumption, and further realizing a longer standby time for the terminal product.

[0130] Figure 6 A schematic diagram of a process for determining the location of a current interfering resource proposed in an embodiment of the present disclosure. Figure 1-5 The embodiment shown, as Figure 6 As shown, the following steps are also included:

[0131] Step 601: if there is no resource block that satisfies a preset condition in the power values ​​of at least two fourth resource blocks, the full bandwidth is divided into two n segments, and respectively determine the power value of the resource block corresponding to the sixth endpoint in each segment.

[0132] Among them, n takes consecutive integers greater than 0. That is, n takes 1, 2, 3, 4, etc.

[0133] In some embodiments, when the power values ​​of at least two fourth resource blocks do not have a resource block that meets the preset condition, it means that the historical interference resource has no reference value for determining the current interference resource, that is, at least two fourth resource blocks are not interference resources, then it is necessary to follow the following steps: Figure 1-Figure 3 The method of the illustrated embodiment determines the location of current interfering resources.

[0134] In some embodiments, the full bandwidth is divided into two n The power value of the resource block corresponding to the sixth endpoint in each segment can be determined by referring to Figure 2 The segmentation method in the embodiment shown in 3 will not be repeated here.

[0135] Step 602: Determine the location of the current interfering resource based on the power value of the resource block corresponding to the sixth endpoint.

[0136] In some embodiments, based on the power value of the resource block corresponding to the sixth endpoint, the position of the current interfering resource can be determined by referring to Figure 1-Figure 3 The steps in the illustrated embodiment will not be described in detail here.

[0137] In summary, the method for determining interference resources proposed in the present invention can calculate the power value of the full bandwidth in segments when the reference signal type is the target type, and then determine the location of the interference resource based on the power value, thereby reducing the amount of calculation and improving the calculation efficiency, so as to achieve the purpose of reducing power consumption and further realize a longer standby time of the terminal product.

[0138] The following is a specific implementation of the interference resource determination method:

[0139] For NR, the maximum bandwidth is 273 RB. When the reference signal type is type 1, the RB distribution is continuous; when the reference signal type is type 2, the resource distribution is discontinuous, which is not conducive to the use of this optimization solution. It is recommended to enable it when type 1. The module can enable this optimization function according to the register configuration when dmrs_type is 1.

[0140] Since the interference area is a relatively concentrated area, based on this characteristic, the full bandwidth calculation is not required, such as Fig. 7A The schematic diagram shown: the first three points are calculated, namely the front, back and middle points, and the bandwidth is divided into two sections;

[0141] The midpoint of these two segments is calculated a second time, and the entire bandwidth is now divided into four equal segments.

[0142] Calculate the power values ​​of the middle points in sections. If you find that among the first five points, only the second and fourth points have larger power values ​​when calculating for the third time, Figure 7B As shown in the schematic diagram: the shaded blocks are interference positions, and the white blocks are not interference positions, which means that the interference area is concentrated in the area of ​​0 to n / 2 on the left, and then the remaining n / 2 area is segmented and calculated to find the boundary position of the interference. Therefore, the PRG block power in the latter half of the area does not need to be calculated, so as to achieve the purpose of reducing the number of operations and thus reducing power consumption.

[0143] In addition, although the communication channel is a rapidly changing channel, in a very short period of time, at the symbol level, the channel should change gradually, and basically there are more scenarios where it changes slowly, such as working in an office, lying on the sofa, walking, and similar scenarios. The change in channel parameters should not be sudden, which can be judged by the CSI channel status. The algorithm changes obviously in a certain period of time in the channel. If it is not obvious or basically unchanged, then the previous calculation result will be instructive for the next calculation result. Alternatively, the next result should be very close to the previous result. There is no need to traverse all resource blocks from the beginning. Using the previous result and inferring the resource blocks near the result can find the interference location faster.

[0144] Specifically, it can be judged according to the CSI channel parameters (including delay spread, signal to noise ratio (SNR), Doppler and other related parameters). When the relevant value does not change much, it indicates that the channel state has not changed much in a short period of time. The historical value can be used to find the interference position first. The boundary value of the previous one or two times (the previous one has two boundary values, and the previous two times have four boundary values) can be used to calculate the power values ​​of these positions first, such as Figure 7CSchematic diagram shown: If there is interference, the point is used as the boundary and the broadband boundary is used as the edge for dichotomy, and the shaded block is the boundary of the interference position; if there is no interference, the calculation is performed according to normal logic.

[0145] In summary, compared with the traditional algorithm, this optimization scheme can reduce the number of calculations and is also simpler to implement, without increasing the difficulty of hardware implementation, making it easier to implement and promote.
