Reference will now be made in detail to embodiments of the present application, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the accompanying drawings are exemplary only for the purpose of explaining the present application and are not to be construed as limiting the present application.

In order to make the technical solutions of the present application better understood by those skilled in the art, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. It is to be understood that the embodiments described are only a few embodiments of the present application and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

Modern wireless communication systems typically include base stations and end users. Taking a wireless communication terminal (such as a mobile phone, etc.) as an example, in a signal receiving direction, a receiving end receives a radio frequency signal through an antenna, the radio frequency signal is converted into a digital baseband signal through processing of a low noise amplifier, an analog filter, analog-to-digital conversion, etc. of a radio frequency module, and then the digital baseband signal is sent to the baseband module for processing, so that the receiving and the detection of the signal are realized.

The channel state measurement is an important indicator of the terminal capability. The channel state measurement comprises a mode supporting measurement, a feedback mode, the number of measurement reports, the number of measurement reference resources and multi-carrier and single-carrier measurement capability. For example, the number of the terminal channel state measurements is large, the number of the measurement modes is large, the number of the supported carriers is large, the measurement of the base station can be responded effectively and timely, the base station can obtain the channel state quickly and accurately, and corresponding scheduling can be given to ensure stable and high-speed transmission rate. According to the disclosed data, the 5G mobile phone supports a 4x4 multiple input and output antenna system, generally supports channel state measurement reporting capability, has a single carrier of 8 and multiple carriers of 8 (or 16), and supports all measurement modes.

In a wireless communication system, channel and signal configuration information of a terminal physical layer is mainly configured on the basis of a wireless resource control layer issued by a base station side, and the coding of 1 is defined by abstract syntax and is transmitted through an air interface signaling, and the wireless resource control layer of the terminal side analyzes the corresponding configuration.

The channel state information is the channel state information reported to the base station by the user terminal, and consists of channel quality indication, precoding matrix indication, precoding type indication and rank indication, the occupied time frequency resource is controlled by the base station, and the base station can perform scheduling adjustment and related work of beam management according to the reported content. The rank indication is a transmission order used by the user terminal in downlink transmission, that is, the number of layers used in downlink transmission is suggested, and only in space division multiplexing, the user terminal needs to send the rank indication to indicate the number of available transmission layers; while in other cases, the rank indication is always equal to 1; the precoding matrix indication is a precoding matrix which is used by the user terminal to suggest the base station to use in downlink transmission, and the precoding matrix is selected on the basis of assuming to use the number of layers of the reported rank indication; the user terminal uses the channel quality indication to tell the scheduler of the base station the downlink channel quality information that the user terminal sees. If the mimo antenna system transmission is used, the channel quality indication may include feedback related to the required mimo antenna system, where the user terminal obtains channel state information by measuring a received downlink reference signal and reports the channel state information to the base station, where the downlink reference signal may be a channel state information reference signal.

Further, as shown in fig. 1, configuration parameters related to csi-rss are all defined in the information measurement configuration 100, wherein the information measurement configuration 100 is mainly divided into two parts: the measurement reference resource configuration information 110 and the measurement report configuration information 120, where the measurement reference resource configuration information 110 mainly includes: non-zero power channel state indication reference symbol information 111, non-zero power channel state indication reference symbol set information 112, channel state indication interference measurement information 113, channel state indication interference measurement set information 114, and the like; the measurement report configuration information 120 mainly includes report configuration information 121, aperiodic report trigger information, and the like 122.

Further, the maximum number of protocol configurations is shown in fig. 1, and may include: 192 non-zero power channel state indication reference symbols 111 information, 64 non-zero power channel state indication reference symbol set 112 information, 32 channel state indication interference measurement 113 information, 64 channel state indication interference measurement set 114 information, 48 reporting configuration 121 information, and 128 aperiodic reporting trigger 122 information. In these configurations, the ue can provide the number of triggered aperiodic reports supporting activation and the number of configuration information reporting supported at the same time through capability reporting.

Further, reporting the configuration information mainly includes: carrier, channel state indication interference measurement collision resource, reporting amount, group beam reporting, etc. The carrier wave represents a service unit to be found in the measurement reference resource configuration, and the reporting determines a mode which should be measured and reported. When the reporting amount is the channel state information reference signal resource indication rank indication channel quality indication mode, information without codebook indication may be configured, the maximum number of protocols thereof is 128, which may be referred to as shown in fig. 2, where fig. 2 indicates reporting configuration 200 and codebook-free indication 210 information included therein, where the codebook-free indication 210 information may include 4 different transmission port types, the port types mainly depend on the capability reported by the user terminal and the number of transmission ports configured by the base station, and different port types correspond to different port numbers and occupy different numbers of bits.

The port types may be a port type 1 (portlet index 1) 211, a port type 2 (portlet index 2) 212, a port type 4 (portlet index 4) 213, and a port type 8 (portlet index 8) 214, and further, the data protocol value ranges of the port information corresponding to different port types are different, specifically, in this embodiment, the data protocol value ranges of the port information data of the port type 1 that is not compressed by the data protocol value ranges of other port types are shown in table 2 below.

TABLE 2

Port type	Protocol value range of data
		Port type 2	0、1
Port type 4	0、1、2、3
		Port type 8	0、1、2、3、4、5、6、7

As shown in table 2, the data protocol value ranges of the port information corresponding to the port type 2 are 0 and 1, the data protocol value ranges of the port information corresponding to the port type 4 are 0, 1, 2 and 3, and the data protocol value ranges of the port information corresponding to the port type 8 are 0, 1, 2, 3, 4, 5, 6 and 7.

For different port types, the user terminal may select the maximum number of layers for performing channel state indication feedback according to the maximum value of the allowed ranks in the port types. The data structure of the device configuration is different for different port types, and specific reference may be made to tables 2 to 5 below.

Table 3 is a configuration data structure of the port type 8, and as can be seen from table 2, the configurable rank numbers of the port types 8 are 1 to 8, and the number of port information of the port types 8 that can be configured corresponding to each rank is the rank number thereof. For example, for a port type 8 with a rank of 8, the configurable number of port information is 8.

Table 4 is a configuration data structure of port type 4, and as can be seen from table 3, the configurable rank numbers of port type 4 are 1 to 4, and the number of port information of port type 4 that can be configured and corresponds to each rank number is its rank number. For example, for a port type 4 with a rank number of 4, the configurable number of port information is 4.

For example, for a port type 2 with a rank number of 2, the configurable number of port information is 2.

TABLE 6

Table 6 shows a configuration data structure of port type 1, and as can be seen from table 5, port type 1 has no configurable rank number or port information number.

With the coming of the 5G era, since it is necessary to support multiple carriers and complex high-order modulation such as 256 quadrature amplitude modulation, mimo antenna system, etc., complex characteristics, it is also necessary to support channel state measurement, and the user terminal selectively supports different types of channel measurement and reports of different feedback modes according to its capability, and feeds back to the base station's capability through wireless signaling, and the base station performs effective downlink data scheduling after receiving it. This makes the user terminal need the baseband module to make accurate evaluation of the computation processing capability and computation storage capability. The calculation processing capacity determines the number of needed DSPs and hardware accelerators, and the calculation storage capacity influences the memory requirement of the user terminal. For example, in the 3rd Generation Partnership project (3 gpp) 5G standard, the mimo antenna system needs to support 4 × 4 mimo, up to 8 × 8. Inevitably, the number of the baseband module operation memory devices is increased on a large scale, which means higher research and development difficulty and cost, and higher power consumption.

In view of the above problems, the inventors provide a data compression method, an apparatus, an electronic device, and a storage medium provided in the embodiments of the present application, which can reduce redundant bit information caused by processor parsing, avoid large-scale memory overhead caused by storage, and greatly reduce storage capacity. The specific data compression method is described in detail in the following embodiments.

Referring to fig. 3, the data compression method provided in the embodiment of the present application may be applied to a data compression system 300, and the data compression system 300 may include a base station 310 and a user terminal 320, where the base station 310 is a public mobile communication base station, and is an interface device for a mobile device to access the internet, and is a form of a radio station, which is a radio transceiver station for performing information transfer with the user terminal through a mobile communication switching center in a certain radio coverage area. Wherein, the base station 310 may transmit data to the user terminal 320 through a downlink, and the user terminal 320 may transmit information to the base station 310 through an uplink. Specifically, the user terminal 320 may be a computer device capable of being used in mobile, for example, the user terminal 320 may be a mobile phone, a notebook computer, a tablet computer, a POS machine, a vehicle-mounted computer, and the like.

Referring to fig. 4, fig. 4 schematically illustrates a flow chart of a data compression method according to an embodiment of the present application. The method of fig. 4 may include the following steps S410 to S440.

Step S410: and acquiring target reporting configuration information sent by a user terminal.

Further, the user terminal receives the indication information sent by the base station according to the configuration, measures the channel, acquires measurement data, and then performs a channel state indication report to the base station, wherein the report comprises the reporting configuration information. As can be seen from the foregoing, reporting the configuration information mainly includes: carrier wave, channel state indication interference measurement conflict resource, reporting mode, reporting amount, group wave beam reporting, no codebook indication information and the like.

Further, for the data compression method designed by the present application, for some embodiments, data compression may be performed according to the obtained target reporting configuration information. Specifically, it may be set that data compression is not performed when reporting configuration information is not acquired, and data compression is performed when target reporting configuration information is acquired, or it may be set that data compression is performed when the number of target reporting configuration information larger than one value is acquired, and data compression is not performed when the number of target reporting configuration information larger than one value is not acquired. Specifically, in this embodiment, for example, after the target reporting configuration information is acquired, the following step S120 is started, and if the target reporting configuration information is not acquired, no data compression is performed and the target reporting configuration information is waited to be acquired.

Step S420: and acquiring a reporting mode of the target reporting configuration information.

In this embodiment, as can be seen from the previous step S410, the reporting configuration information may include a reporting mode and a reporting amount, and further, each reporting configuration is analyzed, so that the reporting mode and the reporting amount information therein may be obtained.

Further, for the data compression method designed in the present application, for some embodiments, the reporting mode corresponding to each received reporting configuration information may be analyzed. Specifically, in this embodiment, all the received reporting configuration information may be numbered, and then the reporting mode corresponding to each reporting configuration information is analyzed according to a certain sequence, so as to obtain the reporting mode. For example, after 20 pieces of reporting configuration information are received, the 20 pieces of reporting configuration information are sequentially numbered by natural numbers increasing from 1, and then are sequentially analyzed one by one from small to large, so as to obtain a reporting mode corresponding to each piece of reporting configuration information. In this embodiment, the reporting mode of the target reporting configuration information may be determined by a parameter of a reporting amount, where the reporting amount may include one or more of the following items: channel Quality Indicator Reference Signal-Reference Signal Received Power (CRI-RSRP) indicated by the Channel state information Reference Signal resource; the Reference Signal Received Power (Ssb-Index-RSRP) of the Synchronization Signal Block; channel state information Reference Signal resource Indication-Rank Indication-Precoding Matrix Indication-Channel Quality Indication (Channel Quality Indicator Signal-Rank Indication-Precoding Matrix Indicator-Channel Quality Indicator, cri-RI-PMI-CQI), namely Channel Quality Indication corresponding to the Channel state information Reference Signal resource Indication, the Rank Indication and the Precoding Matrix Indication; a Channel state information Reference Signal resource Indication-Rank Indication-i1 (Channel Quality Indicator Reference Signal-Rank Indication-i1, cri-RI-i 1), i.e. i1 corresponding to the Channel state information Reference Signal resource Indication and the Rank Indication; a Channel state information Reference Signal resource Indication-Rank Indication-i1-Channel Quality Indication (Channel Quality Indicator Signal-Rank Indication-i1-Channel Quality Indicator, cri-RI-i 1-CQI), that is, a Channel Quality Indication corresponding to the Channel state information Reference Signal resource Indication, the Rank Indication, and i1; channel state information Reference Signal resource Indication-rank Indication-Channel Quality Indication (cri-RI-CQI), namely, channel Quality indications corresponding to the Channel state information Reference Signal resource Indication and the rank Indication; the CSI-RS Resource Indicator-Rank Indicator-layer Indicator-Precoding Matrix Indicator-Channel Quality Indicator (CSI-RS Resource Indicator-Rank Indicator-Level Indicator-Precoding Matrix Indicator-Channel Quality Indicator, cri-RI-LI-PMI-CQI), i.e., the Channel Quality Indicator corresponding to the CSI-RS Resource Indicator, rank Indicator, layer Indicator, and Precoding Matrix Indicator.

Further, in this embodiment, after the reporting mode corresponding to the reporting configuration information is acquired, the process goes to step S430.

Step S430: and acquiring all codebook-free indication information and each port information.

And if the reporting mode is a preset mode, acquiring all codebook-free indication information contained in the target reporting configuration information and each port information corresponding to each codebook-free indication information. Specifically, in this embodiment, the preset mode is a mode in which the report quantity indicates the channel quality indication for the csi-rs resource indication rank. Further, when the reporting amount of the CSI is configured to indicate the channel quality indicator by using the CSI reference signal resource, the method may include: the no codebook indication is configured and the no codebook indication is not configured, wherein for the case that the no codebook indication is configured, the user terminal only needs to report the parameter configuration related to the rank indication with the port type of 8, and for the case that the no codebook indication is not configured, the user terminal needs to indicate which rank the channel state information reference signal port directory is related to, wherein the rank is one of 1, 2, 4 and 8.

Further, in this embodiment, each reporting mode may be determined, and whether to perform data compression may be selected according to the reporting mode. Specifically, in this embodiment, when the reporting mode is determined to be a mode in which the channel state information reference signal resource indicates the rank indication channel quality indication, the compression operation may be continuously performed, and if the reporting mode is determined to be a mode other than the mode in which the channel state information reference signal resource indicates the rank indication channel quality indication, the compression operation is not performed, for example, when the reporting mode is the mode in which the channel state information reference signal resource indicates the rank indication channel quality indication, the reporting mode is a preset mode, and the compression operation may be continuously performed.

Further, in this embodiment, different transmission port types correspond to different rank numbers, different port numbers, and different numbers of bits occupied, and to determine port information, it is necessary to find a port type corresponding to the port information, and then determine the number of bits occupied by the port type and the number of the port information according to the port type. As can be seen from table 2, the data protocol value ranges of the port information corresponding to the port type 2 are 0 and 1, the data protocol value ranges of the port information corresponding to the port type 4 are 0, 1, 2 and 3, the data protocol value ranges of the port information corresponding to the port type 8 are 0, 1, 2, 3, 4, 5, 6 and 7, and the number of the port information corresponding to each port type can be seen from tables 3 to 6.

Further, in this embodiment, for each non-codebook indicating information, each corresponding port information is determined, and then the process jumps to step S440.

Step S440: the storage space of each port information is reduced.

And reducing the storage space of each port information corresponding to each codebook-free indication information.

In some embodiments, reducing the storage space of each port information corresponding to each piece of codebook-free indication information may be to optimize the storage space corresponding to each port information corresponding to each piece of codebook-free indication information, and reduce waste of space may include: replacing the current storage space with a smaller storage space, or storing a plurality of port information corresponding to each non-codebook indication information instead of only one port information by using the current storage space; the content of each port information corresponding to each codebook-free indication information can be compressed by an algorithm, and the size of each port information corresponding to each codebook-free indication information is reduced, so that the storage space is reduced; or the storage space of each port information corresponding to all the codebook-free indication information can be reduced by the whole occupied storage space through algorithm optimization.

The method comprises the steps of obtaining target reporting configuration information sent by a user terminal and obtaining a reporting mode of the target reporting configuration information; judging whether the reporting mode is a preset mode or not, and if the reporting mode is the preset mode, acquiring all codebook-free indication information contained in the target reporting configuration information and each port information corresponding to each codebook-free indication information; and then, the storage space of each port information corresponding to each non-codebook indication information is reduced in sequence. The method provided by the application greatly reduces the storage capacity on the basis of ensuring the information quantity.

Referring to fig. 5, fig. 5 is a flowchart illustrating a data compression method according to an embodiment of the present application, where the flowchart illustrated in fig. 5 includes steps S510 to S550.

Step S510: and acquiring target reporting configuration information sent by a user.

Step S520: and acquiring a reporting mode of the target reporting configuration information.

Step S530: all codebook-free indication information and per-port information are determined.

Steps S510 to S530 have been described in detail in the above embodiments, and are not described again here.

Step S540: and acquiring a target bit number corresponding to each port information.

And acquiring a target bit number corresponding to each port information corresponding to each non-codebook indicating information, wherein the target bit number is smaller than a designated bit number, and the designated bit number is a default storage space.

Further, in this embodiment, the default storage space may be according to a unit size agreed for the base station and the user equipment UE, or may be a unit size set by a modem manufacturer, and specifically, the port information corresponding to each port type may be stored by using 8-bit integer data, taking the general storage of the modem as an example.

Further, for example, for port information of port type 4, it can be known from table 4 that 1+2+3+4=10 configuration numbers are required altogether, at this time, if a default storage space is adopted, that is, the port information corresponding to each port type is stored by using the above 8-bit integer data, then (1 +2+3+ 4) =8bit 80bit storage information is required altogether, at this time, the reporting configuration and codebook-free indication information that a single carrier of a row base station can be configured at most are considered, as shown in fig. 1 and fig. 2, 48 reporting configurations can be configured at most by a single carrier, and 128 codebook-free indication information are calculated, and then it can be calculated that for one reporting configuration information, the port information of port type 4 requires 80bit 48 × 128 4949bit =60kb, wherein 1kb 4byte, 18bit = 102bit.

Further, in this embodiment, the target number of bits also needs to be smaller than a default storage space on the premise that the data size of the port capable of storing the port information is satisfied and the precision of the data is not changed. As an embodiment, a storage space of the same size may be specified for a storage space of each port information corresponding to each non-codebook indicating information, the storage space is smaller than a default storage space, and using the storage space of the same size does not cause data loss or precision reduction. As another embodiment, a storage unit that conforms to the data size of the port information may be sequentially specified for the storage space of each port information corresponding to each non-codebook indicating information, where the storage unit is smaller than a default storage space, and using the storage units with the same size may not cause data loss or precision reduction.

As another embodiment, a storage unit with a default size may be used to store information of multiple ports, specifically, for example, one storage unit with a default size may store information of two ports, and the occupation of storage space may also be reduced.

Step S550: and modifying the storage space of each port information.

And modifying the storage space of each port information corresponding to each non-codebook indication information into a target bit number corresponding to the port information.

Further, in this embodiment, each port information that needs to be compressed may be sequentially compressed according to any one or more methods in the foregoing embodiments. Specifically, the method may include: all the port information needing to be compressed in the current reporting configuration can be obtained firstly, then natural number numbering is carried out on the port information, the natural number numbering is sequentially increased from 1, then the port information is sequentially compressed from small to large from 1, or after all the port information needing to be compressed in the current reporting configuration is obtained, the port information can be classified according to port types, and then each type of the port information is sequentially compressed.

Referring to fig. 6, fig. 6 is a flowchart illustrating a data compression method according to an embodiment of the present application, where the flowchart in fig. 6 includes steps S610 to S660.

Step S610: and acquiring target reporting configuration information sent by a user.

Step S620: and acquiring a reporting mode of the target reporting configuration information.

Step S630: and acquiring all codebook-free indication information and each port information.

In this embodiment, steps S610 to S630 are already described in detail in the above embodiments, and are not described again here.

Step S640: and acquiring the target port type of each port information.

And acquiring the target port type of each port information corresponding to each non-codebook indication information.

In this embodiment, each port information corresponding to each codebook-free indication information corresponds to a port type. Specifically, the port type corresponding to each of the no codebook indicating information may be confirmed by the number of each of the port information corresponding to each of the no codebook indicating information, specifically, as can be known from table 3, if the number of each of the port information corresponding to one of the no codebook indicating information is 1+2+3+4+5+6+7+8=36, then the port type of the port information may be known as 8, as can be known from table 4, if the number of each of the port information corresponding to one of the no codebook indicating information is 1+2+3+4=10, then the port type of the port information may be known as 4, as can be known from table 5, and if the number of each of the port information corresponding to one of the no codebook indicating information is 1+2=3, as can be known as 2, as can be known from table 5, as may be known as 1. For example, in this embodiment, if the number of each port information corresponding to one piece of codebook-free indication information is obtained as 36, it can be known that the port type of the port information is 8.

Further, if there are 4 port types, one storage space can be used for different types of ports. Specifically, the storage may be performed in an ascending order manner, or may be performed in a descending order manner, for example, in this embodiment, as described with reference to table 7 below, a 2-bit storage space may be used in an ascending order manner, the port type 1 is corresponding to 0, the port type 2 is corresponding to 1, the port type 4 is corresponding to 2, and the port type 8 is corresponding to 3; the port type 1 may be 3, the port type 2 may be 2, the port type 4 may be 1, and the port type 8 may be 0, in descending order.

	In ascending order	Descending order of arrangement
			Port type 1	0	3
Port type 2	1	2
			Port type 4	2	1
Port type 8	3	0

Step S650: and obtaining the target bit number corresponding to each target port type.

And obtaining a target bit number corresponding to each target port type based on a corresponding relation between the port type and the bit number obtained in advance so as to obtain the target bit number corresponding to each port information.

For more clear description of step S650, referring to fig. 7, step S651 and step S652 are further included before step S650.

Step S651: and acquiring a value range corresponding to each port type in all the port types corresponding to the preset mode.

In this embodiment, the preset mode is a mode in which the report quantity is a channel state information reference signal resource indication rank indication channel quality indication, which has been described in detail in the previous embodiments and is not described herein again.

Further, as can be seen from table 2, the value ranges corresponding to different port types are different. Further, in this embodiment, the protocol value range of the data corresponding to the port type 1 does not exist, the protocol value range of the data corresponding to the port type 2 is 0, 1, the protocol value range of the data corresponding to the port type 4 is 0, 1, 2, 3, and the protocol value range of the data corresponding to the port type 8 is 0, 1, 2, 3, 4, 5, 6, 7. Specifically, in this embodiment, the value range corresponding to each port type may be obtained according to the corresponding relationship. For example, if the port type is 8, the protocol value range of the data corresponding to the port type is 0, 1, 2, 3, 4, 5, 6, and 7.

Step S652: and taking the storage space corresponding to the port information value range of each port type as the bit number corresponding to each port type.

In this embodiment, the storage space is represented by bits, and because the value ranges of the port information corresponding to each port type are different, different storage spaces can be adopted to store the port information corresponding to each port type, and a method of effective bit number is used, so that waste of the storage space is avoided. Specifically, the storage space should be as small as possible on the premise that the data storage amount can be satisfied and the data precision is guaranteed to be unchanged, so that the storage space is saved. Specifically, in this embodiment, it may be specified that the data protocol value of the port information corresponding to the port type 2 is stored by using the smallest storage unit, the data protocol value of the port information corresponding to the port type 4 is stored by using the slightly larger storage unit, and the data protocol value of the port information corresponding to the port type 8 is stored by using the largest storage unit. For example, as shown in table 8 below, in this embodiment, a 1-bit storage unit may be used to store the data protocol value of the port information corresponding to the port type 2, a 2-bit storage unit may be used to store the data protocol value of the port information corresponding to the port type 4, and a 3-bit storage unit may be used to store the data protocol value of the port information corresponding to the port type 8.

Referring to fig. 8, fig. 8 is a schematic flowchart illustrating a data compression method according to an embodiment of the present application, where the flowchart in fig. 8 includes steps S810 to S860.

Step S810: and acquiring target reporting configuration information sent by a user terminal.

Step S820: and acquiring a reporting mode of the target reporting configuration information.

Step S830: all codebook-free indication information and per-port information are obtained.

In this embodiment, steps S810 to S830 have been described in detail in the previous embodiments, and are not repeated herein.

Step S840: and determining a fixed bit number according to the preset mode.

And determining the fixed bit number according to the value ranges of all the port types corresponding to the preset mode.

Further, the fixed number of bits should be satisfied including: on the premise of meeting the requirements of data volume storage and ensuring that the precision of data is not changed, the data storage device should be as small as possible, and the storage space is saved. For example, a fixed bit number can be determined, where the bit number is greater than the value ranges of all port types and smaller than the bit number corresponding to the default storage space, so that the requirement of data volume storage can be met, and the accuracy of data is guaranteed to be unchanged.

Step S850: and taking the fixed bit number as a target bit number.

And taking the fixed bit number as a target bit number corresponding to each port information corresponding to each non-codebook indication information.

For a more clear description of step S850, reference may be made to fig. 9, and step S850 further includes step S851.

Step S851: and taking the bit value corresponding to the maximum value range as the fixed bit number.

And taking the bit value corresponding to the maximum value range in the value ranges of all the port types corresponding to the preset mode as a fixed bit number.

In this embodiment, a bit value corresponding to the largest value range among the value ranges of all the port types may be used as a fixed bit number, and the bit number can satisfy the requirement of data volume storage and ensure that the precision of data is not changed. Further, as can be seen from table 2, the port type corresponding to the largest value range among the value ranges of all the port types is 8, the value range is 0, 1, 2, 3, 4, 5, 6, and 7, and a total of 8 numbers just correspond to the 3-bit storage unit, so that the 3-bit storage unit can be used as a fixed bit number.

Step S860: and modifying the storage space of each port information.

And modifying the storage space of each port information corresponding to each non-codebook indicating information into a target bit number corresponding to the port information.

In this embodiment, the storage space of each port information may be modified according to the method described in step S850, so as to achieve the purpose of compressing the storage space.

The method comprises the steps of obtaining target reporting configuration information sent by a user terminal and obtaining a reporting mode of the target reporting configuration information; judging whether the reporting mode is a preset mode, and if the reporting mode is the preset mode, acquiring all codebook-free indication information contained in the target reporting configuration information and each port information corresponding to each codebook-free indication information; and then, sequentially reducing the storage space of each port information corresponding to each non-codebook indicating information. The method provided by the application greatly reduces the storage capacity on the basis of ensuring the information quantity.

Referring to fig. 10 and fig. 11 together, fig. 10 is a schematic flowchart illustrating a data compression method according to an embodiment of the present application, where the flowchart illustrated in fig. 10 includes steps S1010 to S1140.

In this embodiment, a single carrier of the base station may carry multiple reporting configurations, and each reporting configuration information may have multiple pieces of codebook-free indication information, and each piece of codebook-free indication information may correspond to a different port type, and the port type may have a different information value range.

Further, to compress the data of the port information corresponding to each reporting configuration, it is necessary to sequentially detect and compress each reporting configuration information according to a certain sequence. Specifically, in this embodiment, a plurality of loop units may be nested and combined with each other, and the determination unit is collocated to complete the data compression method in this embodiment.

Step S1010: and starting.

In this embodiment, the acquired reporting configuration may be used as a starting point for starting execution of the data compression method.

Step S1020: and determining the number of the reported configurations.

In this embodiment, after the number of reporting configurations is determined, a storage space may be divided to store the data, so as to facilitate use in the following steps. For example, after the number of reporting configurations is determined to be 20, a storage space a may be divided, and 20 may be stored in a.

Step S1030: and reporting whether the configuration number is larger than 0.

If the number of reported configurations is not greater than 0, directly jumping to step S1140, and ending the data compression method; if the number of reported configurations is greater than 0, step S1040 is performed to continue executing the data compression method.

Step S1040: the first I =1 index.

In this embodiment, all reporting configurations may be numbered according to a certain method, a storage space is allocated to store the serial number of the current reporting configuration, and then each reporting configuration is sequentially subjected to data compression according to the serial number. Specifically, the reporting configurations may be sequentially numbered according to a natural number sequence that gradually increases from 1, then data compression is performed from the reporting configuration with the sequence number of 1, and a storage space I is allocated to store the sequence number of the current reporting configuration.

Step S1050, whether the reporting mode is cri-RI-CQI or not is judged.

As can be seen from the foregoing embodiments, if the reporting mode is cr-RI-CQI, that is, the reporting mode is when the csi-rs resource indicates rank indication channel quality indication, the method proceeds to step S1070 to continue to perform the data compression method, otherwise, the method proceeds to step S1060 to not compress the data, and then the method proceeds to step S1120.

Step S1060: the data is not compressed.

In this embodiment, when it is determined in the previous step S1050 that the reporting mode is not the csi-rs resource indication rank indicator channel quality indicator, the data compression is not performed, and the step S1120 is directly skipped to execute the operation.

Step S1070: and determining the number of the codebook-free indications.

As can be seen from the foregoing, each reporting configuration may include a plurality of pieces of codebook-free indication information, and in this embodiment, after the number of the codebook-free indication information is determined, a storage space may be divided to exclusively store the data, so that the data is convenient to use in the following steps. For example, after the number of the codebook-free indication information is determined to be 40, a storage space b may be divided, and 40 may be stored in b.

Step S1080: serial number first J =1.

In this embodiment, all the non-codebook indicating information may be numbered according to a certain method, a storage space is allocated to store a sequence number of the current non-codebook indicating information, and then each non-codebook indicating information is sequentially subjected to data compression according to the sequence number. Specifically, the no-codebook indicating information may be sequentially numbered according to a natural number sequence that gradually increases from 1, then data compression is performed starting from the no-codebook indicating information with the sequence number of 1, and a storage space J is allocated to store the sequence number of the current no-codebook indicating information.

Step S1090: and (5) data compression.

Step S10901: data compression is started.

Step S10902: the port type and the number of valid/fixed bits are determined.

Step S10904: the total rank number is determined.

In this embodiment, the total rank numbers corresponding to different port types are different, and therefore, the total rank number of each port type that needs to be compressed needs to be obtained. As can be seen from tables 3 to 6, port type 1 has no corresponding rank number, port type 2 has a rank number of 2, port type 4 has a rank number of 4, and port type 8 has a rank number of 8. For example, after determining that the number of total ranks corresponding to the current port type is 8, a storage space x may be divided, and 8 may be stored in x.

Step S10905: the first M =1 index.

In this embodiment, all the rank numbers may be numbered according to a certain method, and a storage space is allocated to store the sequence number of the current rank number, and then each rank number is sequentially subjected to data compression according to the sequence number. Specifically, the rank numbers may be sequentially numbered according to a natural number sequence that gradually increases from 1, and then data compression is performed starting from the rank number with the rank number of 1, and one storage space M is allocated to store the rank number of the current rank number.

Step S10906: and determining the number of the port information in the rank number.

As can be seen from the foregoing, each rank number may include a plurality of port information numbers, and in this embodiment, after the number of port information, a storage space may be divided to store the data exclusively, so as to facilitate use in the following steps. For example, after the number of the port information is determined to be 8, a storage space y may be divided, and 8 may be stored in y.

Step S10907: the first N =1 index.

In this embodiment, the port information in all the rank numbers may be numbered according to a certain method, a storage space is allocated to exclusively store the serial number of the port information in the current rank number, and then the port information in each rank number is sequentially subjected to data compression according to the serial number. Specifically, the port information in the rank number may be sequentially numbered according to a natural number sequence that gradually increases from 1, and then data compression is performed starting from the port information in the rank number with the sequence number of 1, and one storage space N is allocated to store the sequence number of the port information in the current rank number.

Step S10908: compressing the ports to a valid/fixed number of bits.

This step is described in detail in the above embodiments, and is not described herein again.

Step S10909: whether N is not less than the maximum number of port information in the rank.

In this embodiment, the storage space y allocated in step S10906 and the port information sequence number N in the current rank number may be compared to determine whether the port information sequence number in the current rank number is not less than the maximum number of port information in the rank, if not, step S10911 is performed, and if not, step S10910 is performed.

Step S10910: n plus 1.

In this embodiment, the port information sequence number N in the current rank number is added by 1 to be the new sequence number N, and then the process goes to step S10908 to continue to perform data compression.

Step S10911: whether M is not less than the maximum rank number.

In this embodiment, the storage space x allocated in step S10904 and the rank N of the current rank number may be compared to determine whether the rank M of the current rank number is not less than x, if not, step S10913 is performed, and if not, step S10912 is performed.

Step S10912: and adding 1 to M.

In this embodiment, the sequence number M of the current rank number is added by 1 to be the new sequence number M, and then the process goes to step S10906 to continue to perform data compression.

Step S10913: and completing data compression.

And finishing the data compression, ending the step S1090, and jumping to the step S1100 for execution.

Step S1100: j is not less than the number of no codebook indications.

In this embodiment, the storage space b allocated in step S1070 and the number J of the current no-codebook instruction information may be compared to determine whether the current J is not less than b, if not, step S1120 is performed, and if not, step S1110 is performed.

Step S1110: j plus 1.

In this embodiment, the number J of the current codebook-free indication information is added by 1 as a new number J, and then it jumps to step S1090 to continue data compression.

Step S1120: and whether I is not less than the reported configuration number.

In this embodiment, the storage space a allocated in step S1020 and the sequence number I of the current reporting configuration may be compared to determine whether the current I is not less than a, if not, step S1140 is performed, and if not, step S1130 is performed.

Step S1130: and adding 1 to I.

In this embodiment, the sequence number I of the current reporting configuration is added by 1 to serve as a new sequence number I, and then the step S1050 is skipped to continue to perform data compression.

Step S1140: and (6) ending.

In this embodiment, this step marks the end of the present data compression method.

Further, in this embodiment, the data compression may be performed by using at least one of the effective bit number or the fixed bit number. For example, taking the codebook-free indication of one port type 4 of the 4x4 mimo antenna system as an example, the effective 2-bit compression is adopted, and the compressed and stored bit information is shown in table 9.

TABLE 9

As shown in table 9 above, for the port type 4, after an effective 2-bit data compression method is adopted, only (1 +2+3+ 4) × 2bit =20 + 3bit =20bit is needed to store the data of the entire port type 4, and the data can be compressed and stored in 3 8-bit storage units of the processor, and considering that at most 48 reporting configurations of a single carrier of a base station can be configured and 128 codebook-free indication information parameters thereof, 24bit × 128 × 48=184320bit =18kb is needed in total.

Further, if the fixed bit compression method is adopted, for example, in this embodiment, 3 fixed bits are adopted to store the data of the port type 4, only (1 +2+3+ 4) — 3bit =10 + 3bit =30bit is required to store the data of the entire port type 4, and in consideration of maximum configurable 48 reporting configurations of the single carrier of the base station and 128 codebook-free indication information parameters thereof, 32bit 128 + 48=196608bit =24kb is required in total.

Further, referring to table 10 below, the data compression method can save 60% -70% of the storage space.

Watch 10

It should be noted that the data compression method requires data analysis processing, and it is understood from the above embodiment that the method using fixed-bit-number compression has a smaller amount of calculation than the method using effective-bit-number compression, but occupies a larger storage space, that is, the compression effect is not as good as the effective-bit-number compression method. When the quantity of the relevant configuration is large, the analysis parameter needs a certain time, and at this time, the analysis time can be saved by adopting a compression mode with a fixed bit number.
