Background technique

Standards formulated by the Third Generation Partnership Project (3GPP) standard organization, Long Term Evolution (LTE) system and 5th Generation Mobile Communication Technology New Radio (5GNR) In the system, the network device sends a channel state information reference signal (Chanel State Information-Reference Signal, CSI-RS) to the terminal on a specific time-frequency resource, instructing the terminal to report the CSI information, so that the network device can dynamically Adjust resource allocation strategies for maximum resource utilization efficiency. When the terminal receives the CSI-RS signal resource, it needs to determine the Precoder Matrix Indicator (PMI) information that maximizes the channel capacity. During this process, different types of PMI information will generate different broadband whitening channels. Covariance matrix (Wideband Whitened Channel Covariance, Rwb) information, the generated Rwb information needs to be stored for filtering and smoothing to increase robustness. Moreover, the terminal may need to receive multiple CSI-RS signal resources, and the ports corresponding to these signal resources may also be different. Therefore, how to store Rwb information scientifically has become an urgent problem to be solved.

In the related art, different CSI-RS signals correspond to different ports, and the number of matrix elements of Rwb information corresponding to different ports is different. For each port, the terminal determines the storage space corresponding to the port according to the matrix element of the Rwb information corresponding to the largest port supported by the terminal. The storage space stores the corresponding Rwb information.

However, in the method in the related art, the sum of the storage spaces of multiple ports is the total storage space, and the storage space of each port is determined according to the matrix element of the Rwb information corresponding to the largest port. Therefore, the total storage space determined in this way The space is large, and the total number of signal resources and ports supported by the terminal is limited. Therefore, the actual storage space occupied by the matrix elements of the Rwb information usually only occupies a small part of the total storage space, and a large part of the storage space is idle. state, resulting in inefficient memory usage.

FIG. 1 is a schematic diagram of an implementation environment of a storage method for storing information provided by an embodiment of the present application. Referring to FIG. 1 , the implementation environment includes: a terminal 101 and a network device 102 , and the terminal 101 and the network device 102 can communicate.

It is stipulated in the 3GPP protocol that the terminal 101 needs to report its own capabilities to the network device 102. There are two parameters, one is the total port number of the terminal 101, and the value ranges from 2 to 256, and the other is the terminal 101. The total number of signal resources supported, ranging from 1 to 64. In addition, the port numbers of the antenna ports of the terminal 101 include 1, 2, 4, 8, 12, 16, 24, and 32, different CSI-RS signal resources correspond to different ports, and different ports correspond to the matrix elements for storing information. Different numbers of matrix elements occupy different storage space.

In this embodiment of the present application, the stored information may be Rwb information, whitening channel covariance matrix information, subband whitening channel covariance matrix information, or noise covariance matrix information, which is not specifically limited.

In the following, only the stored information is Rwb information as an example for description. The Rwb information is the channel matrix covariance after whitening, and the dimension is P*P, where P is the port number of the port corresponding to the CSI-RS signal. The whitened channel matrix covariance is a Hermitian matrix with conjugate symmetry, and each element in the i-th row and the j-th column is conjugate with the j-th row and the i-th column element. Therefore, the upper and lower triangular elements of the matrix are the same, so when storing Rwb information, only the upper triangular element or the lower triangular element can be stored. Wherein, i and j are both integers greater than 0. Because when the number of ports of a port is 1, the matrix has only one element, and there is no need to select PMI information. Therefore, in this embodiment of the present application, the case where the number of ports of a port is 1 is not considered for the time being.

In this embodiment of the present application, the terminal 101 can determine the size and number of Rwb information that the terminal 101 needs to store based on the total number of ports, the total number of signal resources, and the number of ports of multiple ports. The number of ports in this embodiment of the present application refers to the port value of the port. For example, 32 ports have 32 ports and 24 ports have 24 ports.

The terminal 101 is a terminal 101 with a wireless communication function, the terminal 101 can communicate with one or more core networks via a radio access network (RadioAccess Network, RAN), and the terminal 101 can be a mobile terminal 101, such as a mobile phone (or referred to as a "cellular" telephone) and a computer with a mobile terminal 101, which may be, for example, a portable, pocket-sized, hand-held, computer-built-in or vehicle-mounted mobile device. The terminal 101 may be a mobile phone, a tablet computer, a computer with a wireless communication function, a wearable device, or the like. In the embodiments of the present application, this is not specifically limited.

The network device 102 is any network device 102 having a wireless transceiver function. For example, the network device 102 is an Access Point (Access Point) in a base station, an evolved Node B (evolved Node B, eNB), a next Generation Node B (gNB), a Wireless Fidelity (Wireless Fidelity, WIFI) system , AP), wireless relay node, wireless backhaul node, transmission point (transmission point, TP) or transmission and reception point (transmission and reception point, TRP) and so on.

Step 201: Receive a first signal resource of a first port.

Step 202: Determine the target port type to which the first port belongs.

Step 203: Store first storage information in the target storage space corresponding to the target port type, where the first storage information is storage information corresponding to the first signal resource.

In a possible implementation manner, storing the first storage information in the target storage space corresponding to the target port type includes:

Based on the first resource identifier of the first signal resource, query the target storage space for second storage information corresponding to the first resource identifier;

In another possible implementation, the method further includes:

If the second storage information cannot be queried, store the first storage information in the storage subspace that is in an idle state in the target storage space;

If there is no storage subspace in an idle state in the target storage space, the third storage information is replaced with the first storage information, and the third storage information is the storage information with the earliest storage time in the target storage space.

In another possible implementation manner, storing the first storage information in the storage subspace where the second storage information is stored includes:

performing smooth filtering on the second storage information and the first storage information to obtain fourth storage information;

Determine the proportional coefficient between the number of ports corresponding to each port and the total number of ports, and obtain multiple proportional coefficients;

Based on multiple scale coefficients, multiple ports are classified to obtain multiple port types.

In another possible implementation manner, based on multiple scale coefficients, multiple ports are classified to obtain multiple port types, including:

Sort multiple scale coefficients;

Determine the length of the array based on the minimum number of ports and the total number of ports, and the minimum number of ports is the minimum number of ports among the ports belonging to the port type;

Determines an array of ports that matches the length of the array.

The embodiment of the present application provides a storage method for storing information. When storing the storage information of signal resources, the method stores the storage information according to the port type to which each port belongs, and different port types correspond to different storage spaces, which can avoid Each port determines the storage space according to the matrix elements of the storage information corresponding to the maximum number of ports, which greatly reduces the determined total storage space and reduces the difference between the actually used storage space and the total storage space, thereby improving the memory Use efficiency.

FIG. 3 is a flowchart of a storage method for storing information provided by an embodiment of the present application, which is executed by a terminal. Referring to FIG. 3 , the method includes:

Step 301: The terminal receives the first signal resource of the first port.

The network device may send the first signal resources of different ports to the terminal, and accordingly, the terminal receives the signal resources of the port on the time-frequency resources corresponding to the port. In this step, the network device sends the first signal resource of the first port to the terminal, and the terminal receives the first signal resource on the time-frequency resource corresponding to the first port.

Before this step, the network device may send a resource instruction to the terminal, where the resource instruction carries at least one of a first resource identifier of the first signal resource and time-frequency information, where the time-frequency information is used to indicate the value of the first signal resource. Sending time and time-frequency resource, the terminal receives the resource instruction, activates the time-frequency resource corresponding to the time-frequency information, and receives the first signal resource sent by the network device on the time-frequency resource when the sending time of the first signal resource arrives .

Step 302: The terminal determines the target port type to which the first port belongs.

In this step, the terminal obtains the target port type by determining the port type including the first port among the plurality of port types.

It should be noted that the multiple port types are obtained by classifying multiple ports supported by the terminal, which will be described in detail below, and will not be described here.

Step 303: Based on the first resource identifier of the first signal resource, the terminal searches the target storage space corresponding to the target port type for the second storage information corresponding to the first resource identifier.

In the embodiment of the present application, when the terminal stores the storage information in the target storage space, it not only stores the storage information, but also stores the resource identifier and storage time corresponding to the storage information, so that the next storage can be stored later according to the resource identifier. information and the storage information with the earliest storage time according to the storage time. Wherein, in the 3GPP protocol, the first resource identifier is Resource Identification.

Based on this, the terminal traverses the second storage information in the target storage space based on the first resource identifier, and determines whether there is second storage information corresponding to the first resource identifier. If the second storage information is queried, step 304 is performed; if the second storage information cannot be queried, step 305 is performed.

Step 304: If the second storage information is queried, the terminal stores the first storage information in the storage subspace where the second storage information is stored.

The first storage information is storage information corresponding to the first signal resource, and the first storage information may be Rwb information, whitening channel covariance matrix information, subband whitening channel covariance matrix information, or noise covariance matrix information, and no Specific restrictions.

If the second storage information is queried, indicating that the storage information corresponding to the first resource identifier has been stored before, the terminal performs smooth filtering on the second storage information and the first storage information to obtain the fourth storage information, and then stores the second storage information. The storage subspace of the storage subspace stores the fourth storage information, and records the storage time and the first resource identifier of the fourth storage information.

In this implementation manner, the terminal may determine the product of the first storage information and the first filter coefficient and the product of the second storage information and the second filter coefficient, respectively, obtain the first product value and the second product value, and then determine the first product The sum value of the value and the second product value is obtained to obtain the fourth storage information.

This process can be represented by the following formula: Rwb ₄ =(1-α)Rwb ₂ +αRwb ₁ , where Rwb ₄ is the fourth storage information, and α and (1-α) are the first filter coefficient and the second filter coefficient, respectively , Rwb ₁ and Rwb ₂ are the first storage information and the second storage information, respectively.

The first filter coefficient and the second filter coefficient may be set and changed as required, and in the embodiment of the present application, the first filter coefficient and the second filter coefficient are not specifically limited.

It should be noted that when the subsequent terminal receives the second signal resource identified by the first resource, when storing the fifth storage information corresponding to the second signal resource, the fourth storage information and the fifth storage information need to be smoothed. filtering, and storing the sixth storage information obtained after filtering in the storage subspace where the fourth storage information was originally stored.

Step 305: If the second storage information cannot be queried, the terminal stores the first storage information in the storage subspace in the idle state in the target storage space.

If the second storage information cannot be queried, it means that the first storage information is a new resource, and a new storage space needs to be arranged to store the first storage information. Find a storage subspace in an idle state, store the first storage information in the storage subspace, and record the storage time and the first resource identifier of the first storage information. If there is no storage subspace in an idle state in the target storage space, the terminal executes step 306 .

Step 306: If there is no storage subspace in an idle state in the target storage space, the terminal replaces the third storage information with the first storage information.

The third storage information is the storage information with the earliest storage time in the target storage space.

In this implementation manner, if there is no storage subspace in an idle state in the target storage space, the historical storage information needs to be released at this time. In this case, the terminal determines the third storage information with the earliest storage time in the target storage space, and releases it. The third storage information is output, the first storage information is stored in the location, and the storage time and the first resource identifier of the first storage information are recorded.

Here, the stored information is Rwb information as an example for description. For example, if the capability of the terminal is to receive at most 8 signal resources and the maximum number of bearer ports is 64, the total number of signal resources is 8, the total number of ports is 64, and the number of ports of multiple ports is 2, 4, 8, and 12 respectively. , 16, 24 and 32. The terminal receives four 16-port signal resources in sequence, and the resource identifiers of these four signal resources are 0, 1, 2, and 3, respectively. Then the Rwb information corresponding to the signal resources with resource identifiers 1 and 2 is released, and then received again. To a 32-port signal resource, the resource identifier of the signal resource is 4. According to the method provided by the embodiment of the present application, the process of storing the Rwb information by the terminal mainly includes the following steps:

(1) The total number of signal resources is 8, and the total number of ports is 64. According to the method provided in the embodiment of the present application, these ports 2, 4, 8, 12, 16, 24, and 32 are divided into 5 port types. 4 and 8 are three port types respectively. Ports 12 and 16 are combined into one port type, and 24 and 32 are combined into one port type. Among them, port 2 requires 3*8 storage space, and port 4 requires 10*8 storage space , port 8 requires 36*8 storage space, port 12/16 requires 136*4+78 storage space, port 24/32 requires 528*2 storage space, and the total storage space is 2070, see Figure 4 (a ).

Among them, the port classification process will be described in detail below, and will not be repeated here.

(2) When four 16-port signal resources are respectively received, find the storage space corresponding to the port type to which port 16 belongs, and arrange them in sequence, see (b) in FIG. 4 .

(3) The Rwb information corresponding to the signal resources with resource identifiers 1 and 2 is released, and the storage subspace corresponding to resource identifier 1 and identifier 2 in the storage space corresponding to port 16 is freed, see (c) in FIG. 4 .

(4) When receiving the signal resource of 32 ports whose resource identifier is 4, find the storage space corresponding to the port type to which port 32 belongs, and then store the Rwb information corresponding to the signal resource in the storage space with the first address of 528*1 storage location, see (d) in Figure 4.

It can be seen that the method provided by the embodiment of the present application has the following two advantages:

First, the signal resources of different ports are stored according to the corresponding positions, aligned and arranged, and the corresponding signal resources can be directly found by the number of ports. At the same time, the signal resources of different ports will not be covered, and there is no memory conflict, which greatly reduces the memory. Managed power consumption.

Second, the storage space required by the corresponding port is opened up according to the port type, which avoids opening up the storage space for each port according to the maximum number of ports, and greatly reduces the memory occupation. Combine 32 ports with 24 ports, and 16 ports with 12 ports. The 12-port signal resources are aligned with the first address of the 16-port signal resources, and the 24-port signal resources are aligned with the first address of the 32-port signal resources. Increase While resources are reused, the memory management method is consistent. In this embodiment, if the matrix element corresponding to each Rwb information is 8 bytes, the required storage space is 2070*8=16560 bytes. Moreover, the memory usage efficiency is (528*2)/2070=51%, and the memory usage efficiency is relatively high.

To sum up, the method provided by the present application can avoid fragmented memory management and additional power consumption caused by memory copying in order to manage fragmented memory, and greatly reduce the complexity of memory management. Moreover, the waste of storage space is avoided, and the use efficiency of the memory is increased.

Similarly, under the premise that the total number of signal resources is 8, the total number of ports is 64, and the number of ports of multiple ports is 2, 4, 8, 12, 16, 24 and 32 respectively, if the In the solution, the process of the terminal storing the Rwb information mainly includes the following steps:

(1) The total number of signal resources is 8, the total number of ports is 64, and each port opens up storage space according to 528*8, see (a) in Figure 5.

(2) When four 16-port signal resources are received respectively, the storage space corresponding to the 16-port is found, and then the Rwb information corresponding to these four signal resources occupies the first address of 528*0 and 528*1 in the storage space respectively. , 528*2 and 528*3, see (b) in FIG. 5 .

(3) The Rwb information corresponding to the signal resources whose resource identifiers are 1 and 2 are released, that is, the two Rwb information whose first addresses are 528*1 and 528*2 are released, see (c) in FIG. 5 .

(4) Receive the 32-port signal resource with the resource identifier 4, find the first free storage space, and store the Rwb information in the storage space, see (d) in FIG. 5 .

According to the above process, this solution needs to consume a large storage space, and the more the total number of signal resources, the larger the storage space occupied. When the number of signal resources is 8 and the total number of ports is 64, each port will open up storage space according to the memory corresponding to 32 ports, then the total storage space is 528*8, and the maximum storage space occupied by the terminal is 528*2 , the memory usage efficiency is (528*2)/(528*8)=25%, and the memory usage efficiency corresponding to the method provided by the embodiment of the present application is 51%, which is higher than the memory usage efficiency corresponding to the method provided by the background technology. doubled. Moreover, when the matrix element corresponding to each Rwb information is 8 bytes, the required storage space is 528*8*8=33792 bytes, while the storage space required by the method provided by the embodiment of the present application is only 16560 bytes , which saves half the memory compared to the method provided by the background art.

It should be noted that, in other solutions in the related art, when storing Rwb information, the terminal stores the Rwb information of the same port in sequence, and when the remaining storage space is not enough to store the Rwb information currently to be stored, the terminal releases a part of the stored Rwb information. and move the unreleased part of the Rwb information to the free storage space according to the respective corresponding ports, and then store the Rwb information currently to be stored. In order to facilitate understanding, the following describes the stored procedure of the program.

Here, the total number of signal resources is 8, the total number of ports is 64, and the number of ports of multiple ports is 2, 4, 8, 12, 16, 24, and 32 as an example for description. And in this process, the terminal receives four 16-port signal resources in turn. The resource identifiers of these four signal resources are 0, 1, 2, and 3, respectively, and then the Rwb information corresponding to the signal resources with resource identifiers 1 and 2 is released. If the signal is dropped, another 32-port signal resource is received, and the resource identifier of the signal resource is 4.

The process mainly includes the following steps:

(1) The total number of signal resources is 8 and the total number of ports is 64, then at most two 32-port signal resources need to be stored, and the maximum storage space requirement is 2*528=1056, see (a) in Figure 6.

(2) When four 16-port signal resources are respectively received, they are arranged in sequence according to the storage space required by the port, see (b) in FIG. 6 .

(3) The Rwb information corresponding to the signal resources whose resource identifiers are 1 and 2 are released, see (c) in FIG. 6 .

(4) The signal resource of 32 ports with resource identifier 4 is received. At this time, there is no continuous storage space in the storage space enough to store the Rwb information corresponding to the signal resource. At this time, the terminal corresponds to the signal resource with resource identifier 3. The Rwb information is moved to the storage location of the Rwb information corresponding to the signal resource with the original resource identifier of 1, and then the Rwb information corresponding to the signal resource with the resource identifier of 4 is stored, see (d) in FIG. 6 .

It can be seen that when the storage space is insufficient, the solution needs to move the Rwb information, which leads to complicated memory management, and increases the power consumption because the Rwb information needs to be copied.

However, when the method provided by the embodiment of the present application stores the Rwb information, it does not need to move the Rwb information, and also does not need to copy the Rwb information, thereby reducing the storage complexity.

The embodiment of the present application provides a storage method for storing information. When storing the storage information of signal resources, the method stores the storage information according to the port type to which each port belongs, and different port types correspond to different storage spaces, which can avoid Each port determines the storage space according to the matrix elements of the storage information corresponding to the maximum number of ports, which greatly reduces the determined total storage space and reduces the difference between the actually used storage space and the total storage space, thereby improving the memory Use efficiency.

FIG. 7 is a flowchart of classifying multiple ports according to an embodiment of the present application. Referring to FIG. 7 , the method includes:

Step 701: The terminal determines the total number of ports and the total number of signal resources supported by the terminal.

It is stipulated in the 3GPP protocol that the terminal needs to report its own capabilities. There are two parameters, one is NZP-CSI-RS-ActBWP-AllCC, which represents the total number of ports. The value of the total number of ports ranges from 2 to 256. The other is NZP-CSI-RS-ActBWP-AllCC, which represents the total number of signal resources, and the value range of the total number of signal resources is 1-64.

For example, if a terminal supports up to 8 signal resources and the total number of ports that can be carried is 64, the terminal supports up to 2 signal resources of 32 ports, 4 signal resources of 16 ports, and 8 signal resources of 8 ports. Of course, various ports can also be arranged and combined, as long as the total number of signal resources is less than or equal to 8 and the total number of ports is less than or equal to 64.

Step 702: The terminal classifies the multiple ports based on the number of ports and the total number of ports supported by the terminal to obtain multiple port types.

This step can be achieved through the following steps (1) to (2), including:

(1) The terminal determines the proportional coefficient between the number of ports corresponding to each port and the total number of ports, and obtains multiple proportional coefficients.

For each port, the terminal determines the ratio of the total port number to the port number of the port, and obtains the proportional coefficient corresponding to the port, which is an integer proportional coefficient or a non-integer proportional coefficient.

For example, the total number of ports of the terminal is 64. For 16 ports, the ratio of the total number of ports to the number of ports of the port is 4, which is an integer scale factor. For 24 ports, the ratio of the total number of ports to the number of ports of the port is about 2.7, which is a non-integer scale factor.

It should be noted that, when the number of ports of a port is 1, the matrix has only one element, and there is no need to select PMI information. Therefore, in this embodiment of the present application, the case where the number of ports of a port is 1 is temporarily ignored.

(2) The terminal classifies multiple ports based on multiple proportional coefficients to obtain multiple port types.

The terminal sorts the multiple scale coefficients, and for the sorted multiple scale coefficients, determines the port corresponding to each integer scale coefficient in the adjacent multiple integer scale coefficients as a class, and sets the adjacent non-integer scale coefficients and The ports corresponding to the integer scale coefficients are combined into one class to obtain multiple port types.

In this implementation manner, the terminal may sort the multiple scale coefficients in descending order, or sort the multiple scale coefficients in descending order, which is not specifically limited. Since some scale coefficients are integer scale coefficients and some scale coefficients are non-integer scale coefficients, there may be cases where the adjacent scale coefficients are non-integer scale coefficients and integer scale coefficients, or there may be adjacent scale coefficients that are all integers In the case of scale coefficients, in this case, for multiple adjacent integer scale coefficients, the terminal determines the port corresponding to each integer scale coefficient as a class, and for adjacent non-integer scale coefficients and integer scale coefficients, the terminal will The ports corresponding to the non-integer scale coefficient and the integer scale coefficient are combined into one type.

For example, for ports 2, 4, 8, 12, 16, 24 and 32, the proportional coefficients determined according to the above method are 32, 16, 8, 5.3, 4, 2.7 and 2, respectively. After sorting to the largest order, they are 2, 2.7, 4, 5.3, 8, 16 and 32 respectively. For the proportional coefficients of 2 and 2.7, the ports corresponding to these two proportional coefficients are combined into one class, that is, ports 32 and 24 The ports are combined into one class. For the proportional coefficients of 4 and 5.3, the ports corresponding to the two proportional coefficients are combined into one class, that is, the 16 ports and the 12 ports are combined into one class. For the proportional coefficients of 8, 16 and 32, these three If the scale coefficients are integers, the ports corresponding to each scale coefficient are determined as one class, that is, 8 ports are determined as one class, 4 ports are determined as one class, and 2 ports are determined as one class.

It should be noted that, for the case where there is a non-integer scale coefficient between two adjacent integer scale coefficients, if the scale coefficients are sorted from small to large, the terminal will combine the non-integer scale coefficient with its previous integer scale coefficient as One category, if the scale coefficients are sorted in descending order, the terminal combines the non-integer scale coefficient and the next integer scale coefficient into one category.

Referring to Table 1, for example, the total number of ports is 64, the total number of signal resources is 8, and the storage information is Rwb information. It can be seen from Table 1 that for ports 2, 4, 8, 12, 16, 24 and 32, According to the above method, the terminal combines 12 ports and 16 ports into one type, 24 ports and 32 ports into one type, and the other ports are each one type, and finally 5 port types are obtained.

Table 1 Relationship between port type, number of lower triangular elements and number of Rwb information

port type 32/24 16/12 8 4 2 The number of lower triangle elements 528 136/78 36 10 3 Number of Rwb messages 2 5 8 8 8

Step 703: The terminal determines the storage space corresponding to each port type based on the multiple port types, the total number of ports and the total number of signal resources.

This step can be achieved through the following steps (1) to (3), including:

(1) For each port type, the terminal determines the port array corresponding to the port type based on the port type and the total number of ports.

The terminal first determines the length of the array based on the minimum number of ports and the total number of ports, and then determines the port array that matches the length of the array. The array length of the port array is not greater than the total number of signal resources, and the minimum number of ports belongs to the port. The smallest number of ports among the types of ports.

In this implementation, the terminal determines the ratio of the total number of ports to the minimum number of ports. If the ratio is not greater than the total number of signal resources and is an integer, the terminal directly determines the ratio as the array length. If the ratio is greater than the total signal resources The number of resources, the terminal determines the total number of signal resources as the array length. If the ratio is not greater than the total number of signal resources and is a non-integer, the terminal determines the integer part of the ratio as the array length. The size is the maximum amount of stored information that the port can carry.

For example, the stored information is Rwb information. For a port type, the port type includes 24 ports and 32 ports, the minimum number of ports among the two ports is 24, the total number of ports of the terminal is 64, and the total number of signal resources is 8 , the terminal determines the ratio between 64 and 24, which is about 2.7. It can be seen that the ratio is not greater than the total number of signal resources and is a non-integer, and the terminal determines the integer part of 2.7, that is, 2 as the array length of the port type , that is, the storage subspace corresponding to the port type stores at most 2 Rwb information. For another port type, the port type only includes 4 ports, the terminal determines the ratio of 64 to 4, the ratio is 16, and it can be seen that the ratio is greater than the total number of signal resources, then the terminal directly determines the total number of signal resources 8 as The array length of the port type, that is, the storage subspace corresponding to the port type can store up to 8 pieces of Rwb information.

Among them, the initial value of the port array can be set and changed as required. For example, the initial value of the port array is -1, indicating that the storage subspace is not occupied, and the array length of the port array is 8, then the port array There are 8 initial values.

(2) The terminal determines the number of matrix elements of the stored information corresponding to the port type.

If the stored information is Rwb information, the number of matrix elements is the number of upper triangular elements or the number of lower triangular elements in the Rwb information, and the number of matrix elements of the Rwb information corresponding to different ports is different, for example, 32 ports correspond to The number of matrix elements of Rwb information is 528, the number of matrix elements of Rwb information corresponding to 24 ports is 300, and the number of matrix elements of Rwb information corresponding to 16 ports is 136, see Table 2.

Table 2 Number of lower triangular elements corresponding to each port

port 32 twenty four 16 12 8 4 2 The number of lower triangle elements 528 300 136 78 36 10 3

In this step, the terminal determines the ratio between the maximum number of ports in the ports belonging to the port type and the total number of reference ports, obtains the first ratio, determines the difference between the array length of the port array and the first ratio, and obtains the first ratio. a difference. If the first difference is equal to 0, the terminal determines that the number of matrix elements of the stored information corresponding to the maximum port number is the number of matrix elements of the stored information corresponding to the port type. If the first difference is greater than 0, the terminal determines that the number of matrix elements of the stored information corresponding to the maximum number of ports and the minimum number of ports respectively is the number of matrix elements of the stored information corresponding to the port type.

If the stored information is Rwb information, it can be seen from Table 1 that the number of matrix elements of the Rwb information corresponding to the port types to which ports 32 and 24 belong is 528, and the matrix of Rwb information corresponding to the port types to which ports 16 and 12 belong The number of elements is 136 and 78.

(3) The terminal determines the storage space corresponding to the port type based on the port array corresponding to the port type and the corresponding number of matrix elements.

This storage space includes not only storage capacity, but also storage location. The storage capacity can meet the storage requirements of each port in the port type, and the storage location is the memory location corresponding to the maximum number of ports in the port type. For example, for a port type, the port type includes 24 ports and 32 ports, the Rwb information corresponding to the 24 ports and the Rwb information corresponding to the 32 ports are both stored in the memory locations aligned with the 32 ports.

The process of determining the storage capacity corresponding to the port type by the terminal may be implemented through the following process: if the first difference is equal to 0, the terminal determines the product value of the array length of the port array and the number of corresponding matrix elements, and obtains the corresponding port type storage capacity. If the first difference is greater than 0, the terminal determines the product of the number of matrix elements corresponding to the maximum number of ports and the first ratio, obtains the first product value, and determines the number of matrix elements corresponding to the minimum number of ports and the first ratio. The difference value is multiplied to obtain the second product value, and the sum of the first product value and the second product value is determined as the storage capacity.

For example, the total number of ports is 64, the total number of signal resources is 8, and the storage information is Rwb information. For a port type, the port type includes 24 ports and 32 ports, the terminal directly determines the ratio of 64 to 32, and obtains the first The ratio is 2. According to the above step (1), it can be known that the array length of the port type is 2, and the difference between the array length and the first ratio is 0, then the terminal determines the product of the array length 2 and the number of matrix elements corresponding to the 32 ports 528 value, the storage capacity corresponding to this port type is 528*2, see Figure 8.

For another port type, the port type includes 12 ports and 16 ports, then the terminal determines the ratio of 64 to 16, and obtains the first ratio of 4. According to the above step (1), it can be determined that the array length of this port type is 5, and the If the difference between the array length and the first ratio is 1, the terminal determines the product of the number of matrix elements corresponding to port 16, 136 and the first ratio of 4, to obtain the first product value of 136*4, and determines the number of matrix elements corresponding to port 12. The product of the number 78 and the first difference value 1 obtains the second product value 78*1, and the sum of the first product value 136*4 and the second product value 78*1 is determined to be the storage capacity. Continue to refer to FIG. 8 . It can also be seen from FIG. 8 that the quantity of Rwb information corresponding to each port type is not greater than 8.

It should be noted that steps 701-703 are the process of classifying multiple ports to obtain multiple port types, which only needs to be performed once, and steps 301-306 can be directly performed when signal resources are subsequently received.

In the embodiment of the present application, the terminal obtains multiple port types by classifying multiple ports, and develops the storage capacity required by the corresponding port according to the port type, avoiding the need for each port to develop storage capacity according to the maximum number of ports, greatly reducing the need for The memory usage is reduced, thereby improving the efficiency of memory usage.
