Detailed Description
In order to make the objects, technical solutions and advantages of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings, and it is obvious that the described embodiments are some, but not all embodiments of the present invention. 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 invention.
The following describes the data parsing method of the present invention, applied to a base station, with reference to fig. 2, including:
optionally, the base station sends downlink data to the terminal, and if the data amount of the downlink data is small, the downlink data may be directly configured in the downlink control information DCI of the PDCCH, so that the terminal may directly analyze the downlink data in the downlink control information DCI.
As shown in fig. 3, after the base station and the terminal complete downlink synchronization and uplink synchronization, the configured physical downlink control channel PDCCH is sent to the terminal through the medium access control layer.
As shown in fig. 4, the step of performing downlink synchronization and uplink synchronization between the base station and the terminal includes, first, configuring parameters of the base station, and constructing a cell; then, the terminal searches the cell and completes downlink synchronization with the base station through the SSB; then, the terminal completes the uplink synchronization with the base station through random access; then, the NR terminal monitors the PDCCH of the base station and performs blind detection on the PDCCH; and under the condition that the blind detection is successful, starting to analyze the configured physical downlink control channel PDCCH.
Optionally, the terminal first parses the downlink control information DCI from the configured PDCCH.
After the downlink control information DCI is parsed, downlink data can be parsed from the downlink control information DCI according to the indication of the frequency domain resource indication value in the DCI.
Compared with the prior art that the downlink data can be acquired after the PDCCH and the PDSCH are analyzed at the same time, the downlink data is directly configured in the PDCCH, and the downlink data can be analyzed from the DCI in the PDCCH only by indicating the frequency domain resource indicated value in the DCI in the PDCCH. On one hand, the PDCCH is directly analyzed, downlink data can be obtained without analyzing the PDSCH, and time delay is effectively reduced; on the other hand, the downlink data can be transmitted to the terminal only by issuing the PDCCH configured with the downlink data, so that the problem of large physical resource occupation caused by issuing the PDSCH is effectively solved, and the physical resource occupation is reduced.
In this embodiment, the downlink data is directly configured in the downlink control information of the physical downlink control channel, and the configured physical downlink control channel is sent to the terminal, so that the terminal can acquire the downlink data only by analyzing the downlink control information of the physical downlink control channel, which not only can reduce the time delay caused by analyzing the PDSCH, but also can reduce the physical resources occupied by issuing the PDSCH.
On the basis of the foregoing embodiment, in this embodiment, the configuring, by the base station, the downlink data in the downlink control information of the physical downlink control channel includes: and if the resource space occupied by the downlink data is smaller than the resource space occupied by a field after the frequency domain resource indication value in the downlink control information before configuration, configuring the downlink data in the field.
Optionally, the downlink control information DCI has a resource space with one bit for storing a format indicator (format identifier) of the DCI, a part of the resource space is used for storing a frequency domain resource indication value, and a field after the frequency domain resource indication value is used for storing data and/or instructions that can be indicated by the frequency domain resource indication value, and the like.
Therefore, before configuring the downlink data in the downlink control information DCI, it is necessary to determine whether the resource space occupied by the downlink data is smaller than the resource space occupied by the field after the frequency domain resource indication value of the downlink control information DCI.
If the number of the downlink data is less than the number of the downlink data, the downlink data is configured in the field; if the number of the downlink data is larger than or equal to the number of the downlink data, the downlink data can be split.
And then, continuously judging whether the resource space occupied by the split downlink data is smaller than the resource space occupied by the field. And under the condition that the resource space occupied by the split downlink data is smaller than the resource space occupied by the field, the split downlink data is configured in the field.
As shown in table 1, the configured DCI includes a format identifier (format identifier), resource information (Resource information), and downlink data.
Table 1 DCI containing downlink data
The Frequency domain resource indication value (Frequency domain resource assignment) exists in the resource information, and is used for indicating the terminal to analyze a field behind the Frequency domain resource indication value in the DCI according to a preset protocol format corresponding to the Frequency domain resource indication value.
In this embodiment, before configuring downlink data in the downlink control information DCI, the resource occupied by the downlink data is compared with the resource space occupied by the field, so as to ensure the validity of the configured field, and further ensure the validity of the PDCCH sent to the terminal.
On the basis of the foregoing embodiment, in this embodiment, the downlink data is analyzed from the configured field according to a preset protocol format corresponding to the frequency domain resource indication value when the frequency domain resource indication value exists in a preset value by the terminal; and the corresponding relation between the frequency domain resource indicated value and the preset protocol format is preset.
The preset value is a value preset according to actual requirements; the number of the preset values can be one or more, and is specifically set according to actual requirements.
Alternatively, the frequency domain resource indication value in the existing DCI can only be a value specified by a normal protocol and is used to indicate control information specified by the normal protocol.
The bit width of the frequency domain resource indication value is usually designed according to the frequency domain resource indication value specified by the normal protocol. The number of all available values of the frequency domain resource indication value can be obtained according to the bit width, and the frequency domain resource indication value usually specified by the normal protocol only occupies a part of the available values, so that a large amount of residual available values in all the available values are not used.
Optionally, since the number of available values occupied by the frequency domain resource indication value specified by the normal protocol is different in different DCI formats. Accordingly, the remaining available value may be calculated from the format of the DCI and the bit width of the frequency domain resource indication value.
The DCI format includes DCI1_0, DCI1_1, DCI0_0, DCI0_1, and the like, which is not specifically limited in this embodiment. DCI1_0 and DCI1_1 are used to store downlink control information, and DCI0_0 and DCI0_1 are used to store uplink control information.
The calculation formula of the bit width of the frequency domain resource indicated value is as follows:
wherein W represents a bit width of the frequency domain resource indication value,
number of bits for BWP for downlink, <' > based on>
Is a round-up operation.
The calculation formula of the number P of all available values of the frequency domain resource indication value is as follows:
the calculation formula of the number U of the available values occupied by the frequency domain resource indicated value specified by the normal protocol is as follows:
in the DCI1_0 format, in addition to the frequency domain resource indication value specified by the normal protocol, the frequency domain resource indication value is considered to indicate the scrambled initial random access under the condition that all the frequency domain resource indication values are specified to be 1; accordingly, the field following the frequency domain resource indication value is used to deposit the dedicated initial random access resource.
Therefore, in the DCI1_0 format, the number of remaining available values S1 is calculated by:
the calculation formula of the number S2 of remaining available values in all frequency domain resource indication values in DCI formats other than DCI1_0 format is:
as shown in table 2, in the DCI1_0 format, when the bit width occupied by the frequency domain resource indication value specified by the normal protocol is 16, the number P =65536 of all available values of the frequency domain resource indication value, and the number occupied by the frequency domain resource indication value specified by the normal protocol is U =37401, 28134 available values remain. Special use of the remaining 28134 available values can be set as required and the fields following the indication value of the frequency domain resources in the DCI can be parsed according to the special use.
TABLE 2 configuration table of frequency domain resource indication values
In summary, in order to fully utilize resources, in this embodiment, a special purpose is set for the remaining available values in all frequency domain resource indication values, and accordingly, special data is configured for the fields following the frequency domain resource indication values in DCI, so that the terminal can analyze the fields configured with the special data according to the special purpose of the remaining available values.
Optionally, a plurality of available values may be set as preset values in the remaining available values according to actual requirements.
In summary, the frequency domain resource indication value may be a value defined by a normal protocol, or may be a value preset in the remaining available values according to actual needs. Different frequency domain resource indication values correspond to different indication functions and the content of the fields following the different frequency domain resource indication values are also different.
For example, the protocol specifies that the frequency domain resource indicator value is used to indicate scrambled initial random access in case all characters of the frequency domain resource indicator value are 1; accordingly, a field following the frequency domain resource indication value is used for storing a dedicated initial Random Access resource (RACH Info). As shown in table 3, the format of DCI containing dedicated initial random access resources.
Table 3 DCI with dedicated initial random access resources
For example, the frequency domain resource indication value is a preset value from the remaining available values, and the frequency domain resource indication value is set to indicate downlink data analysis; correspondingly, the field behind the frequency domain resource indication value is used for storing the downlink data.
When the configured field is analyzed, it is required to determine whether the frequency domain resource indication value exists in a preset value.
And if so, analyzing the downlink data from the configured field according to a preset protocol format corresponding to the frequency domain resource indication value. If the field does not exist, the field behind the frequency domain resource indication value can only be used for storing the control information corresponding to the normal protocol, and the field can only be analyzed according to the normal protocol.
According to the embodiment, special purposes can be set for available values occupied by the frequency domain resource indicated values specified by the protocol according to actual requirements, so that the terminal analyzes the fields configured with the special purposes according to the special purposes, the purposes of the remaining available frequency domain resource indicated values can be flexibly designed, and rich application scenes can be expanded based on all the remaining available frequency domain resource indicated values; and all available frequency domain resource indicated values can be fully utilized, and resource waste is avoided.
On the basis of the foregoing embodiment, in this embodiment, before configuring the downlink data in the field, the method further includes: and calculating the resource space occupied by the field according to the resource space occupied by the downlink control information and the resource space occupied by the frequency domain resource indicated value.
Optionally, a calculation formula for calculating the resource space N occupied by the frequency domain resource indication value is as follows:
N＝W；
the formula for calculating the resource space occupied by the field is as follows:
Y＝M-N-I；
wherein, M is the resource space occupied by the downlink control information DCI, and I is the resource space occupied by the field before the frequency domain resource indication value in the DCI.
If the resource space occupied by the DCI is 44bits, the resource space occupied by the field before the DCI intermediate frequency domain resource indication value is 1bits, the resource space occupied by the field after the DCI intermediate frequency domain resource indication value is 16bits, and the resource space occupied by the field after the DCI intermediate frequency domain resource indication value is 27bits.
On the basis of the foregoing embodiments, before sending the configured physical downlink control channel to the terminal in this embodiment, the method further includes: and sending a system information block of the base station to the terminal so that the terminal can analyze a preset protocol format corresponding to the frequency domain resource indicated value from the system information block.
As shown in fig. 5, after the base station and the terminal complete downlink synchronization through the SSB, a system information block needs to be sent to the terminal. After receiving the system information block, the terminal device may analyze a preset protocol format corresponding to the frequency domain resource indication value from the system information block.
The system information block includes a frequency domain resource indication value, a preset protocol format corresponding to the frequency domain resource indication value, an effect of the frequency domain resource indication value, and the like, which is not specifically limited in this embodiment.
The system information block may include all frequency domain resource indication values, the functions of all frequency domain resource indication values, and the protocol formats corresponding to all frequency domain resource indication values.
In this embodiment, the system information block carrying the protocol format and the function of the frequency domain resource indication value is sent to the terminal, so that the terminal can obtain the protocol format and the function of the frequency domain resource indication value, and correctly analyze the field after the frequency domain resource indication value according to the protocol format of the frequency domain resource indication value.
On the basis of the above embodiments, the present embodiment further includes: configuring an uplink authorization instruction of a physical uplink shared channel in downlink control information of the physical downlink control channel before configuration; and sending the physical downlink control channel configured with the uplink authorization instruction to the terminal, so that the terminal can analyze the uplink authorization instruction from the downlink control information of the physical downlink control channel configured with the uplink authorization instruction.
Optionally, the Uplink grant instruction of the Physical Uplink Shared Channel (PUSCH) may be configured in a field after the frequency domain resource indicator value in the downlink control information DCI in a manner of configuring the downlink data.
Table 4 DCI containing uplink grant instruction
As shown in table 4, the configured DCI includes a Frequency hopping flag (Frequency hopping flag), a PUSCH Frequency domain resource configuration (PUSCH Frequency domain), a PUSCH time domain resource configuration (PUSCH time domain), a Modulation and Coding Scheme (MCS), an uplink grant command (Transmission Control Protocol command for PUSCH, TPC command for PUSCH), and a Channel State Information request (CSI request).
And then, analyzing the field uplink authorization instruction according to a downlink data analysis mode to obtain the uplink authorization instruction. In this way, the uplink authorization instruction can be directly configured in the downlink control information of the physical downlink control channel, and the configured physical downlink control channel is sent to the terminal, so that the terminal can obtain the uplink authorization instruction only by analyzing the downlink control information of the physical downlink control channel, thereby not only reducing the time delay caused by analyzing the PUSCH, but also reducing the physical resources occupied by issuing the PUSCH.
In addition, the frequency domain resource indication value can be set according to actual requirements, the special purpose of the set frequency domain resource indication value is designed, and data corresponding to the special purpose is configured in the DCI according to the actual requirements. As shown in table 5, the DCI includes data for special purposes.
TABLE 5 DCI with special purpose data
After the terminal is connected with the base station, uplink and downlink data packets need to be sent, a large number of PDCCH and PDSCH resources are needed in the scene, and each corresponding PDSCH is a small data packet. In the present embodiment, the PDCCH is directly utilized to transmit various types of data, such as downlink data and uplink grant commands.
The data analysis method in the embodiment can be used in various scenes of the internet of things. For example, in the meter reading service of the intelligent water meter and the intelligent electric meter, the base station equipment can configure the uplink authorization instruction in a field behind the frequency domain resource indicated value in the DCI, set the frequency domain resource indicated value as a preset value and used for activating the meter reading instruction, and the terminal obtains the uplink authorization instruction by analyzing the DCI, completes a meter reading task according to the uplink authorization instruction and uploads a meter reading result to the base station.
And if the intelligent automobile scene is detected, the base station sends a positioning information reporting instruction to the automobile through the frequency domain resource indicated value of the PDCCH, and the automobile completes positioning data reporting through uplink authorization provided by the PDCCH.
In the embodiment, the special purpose corresponding to the frequency domain resource indicated value can be flexibly set according to the real-time requirement, so that the data analysis method can be used in various scenes, and is wide in application range and good in practicability.
As shown in fig. 6, the data parsing method provided in this embodiment is applied to a terminal, and includes:

Here, the downlink control information of the physical downlink control channel is configured with downlink data, and is further configured with an uplink grant instruction, and the like, which is not specifically limited in this embodiment.
Optionally, the terminal first parses the downlink control information DCI from the configured PDCCH.
After the downlink control information DCI is parsed, downlink data can be parsed from the downlink control information DCI according to the indication of the frequency domain resource indication value in the DCI.

On one hand, the PDCCH is directly analyzed, downlink data can be obtained without analyzing the PDSCH, and time delay is effectively reduced; on the other hand, the downlink data can be transmitted to the terminal only by issuing the PDCCH configured with the downlink data, so that the problem of large physical resource occupation caused by issuing the PDSCH is effectively solved, and the physical resource occupation is reduced.
In this embodiment, the downlink data is directly configured in the downlink control information of the physical downlink control channel, and the configured physical downlink control channel is sent to the terminal, so that the terminal can acquire the downlink data only by analyzing the downlink control information of the physical downlink control channel, which not only can reduce the time delay caused by analyzing the PDSCH, but also can reduce the physical resources occupied by issuing the PDSCH.

The bit width of the frequency domain resource indication value is usually designed according to the frequency domain resource indication value specified by the normal protocol. The number of all available values of the frequency domain resource indication value can be obtained according to the bit width, and the frequency domain resource indication value usually specified by the normal protocol only occupies a part of the available values, so that a large amount of residual available values in all the available values are not used.
Optionally, since the number of available values occupied by the frequency domain resource indication value specified by the normal protocol is different under different DCI formats. Accordingly, the remaining available value may be calculated according to the format of the DCI and the bit width of the frequency domain resource indication value.
The DCI format includes DCI1_0, DCI1_1, DCI0_0, DCI0_1, and the like, which is not specifically limited in this embodiment. DCI1_0 and DCI1_1 are used to store downlink control information, and DCI0_0 and DCI0_1 are used to store uplink control information.
The calculation formula of the bit width of the frequency domain resource indicated value is as follows:
wherein W represents a bit width of the frequency domain resource indication value,
a number of bits for BWP for the downlink, <' >>
Is a round-up operation.
The formula for calculating the number P of all available values of the frequency domain resource indication value is:
the calculation formula of the number U of the available values occupied by the indicated values of the frequency domain resources specified by the normal protocol is as follows:
in the DCI1_0 format, in addition to the frequency domain resource indication value specified by the normal protocol, the frequency domain resource indication value is considered to indicate the scrambled initial random access under the condition that all the frequency domain resource indication values are specified to be 1; accordingly, the field following the frequency domain resource indication value is used to deposit the dedicated initial random access resource.
Therefore, in the DCI1_0 format, the number of remaining available values S1 is calculated by:
the calculation formula of the number S2 of remaining available values in all frequency domain resource indication values in DCI formats other than DCI1_0 format is:
in summary, in order to fully utilize resources, in this embodiment, a special purpose is set for the remaining available values in all frequency domain resource indication values, and accordingly, special data is configured for the fields following the frequency domain resource indication values in DCI, so that the terminal can analyze the fields configured with the special data according to the special purpose of the remaining available values.
Optionally, a plurality of available values may be set as preset values in the remaining available values according to actual requirements.
In summary, the frequency domain resource indication value may be a value defined by a normal protocol, or may be a value preset in the remaining available values according to actual needs. Different frequency domain resource indication values correspond to different indication functions and the content of the fields following the different frequency domain resource indication values are also different.
For example, the protocol specifies that the frequency domain resource indicator value is used to indicate scrambled initial random access in case all characters of the frequency domain resource indicator value are 1; accordingly, the field following the frequency domain resource indication value is used to deposit the dedicated initial random access resource.
For example, the frequency domain resource indication value is a preset value from the remaining available values, and the frequency domain resource indication value is set to indicate downlink data analysis; correspondingly, the field behind the frequency domain resource indication value is used for storing the downlink data.
When the configured field is analyzed, it is required to determine whether the frequency domain resource indication value exists in a preset value.
And if so, analyzing the downlink data from the configured field according to a preset protocol format corresponding to the frequency domain resource indication value. If the field does not exist, the field behind the frequency domain resource indication value can only be used for storing the control information corresponding to the normal protocol, and the field can only be analyzed according to the normal protocol.
According to the embodiment, special purposes can be set for available values occupied by the frequency domain resource indicated values specified by the protocol according to actual requirements, so that the terminal analyzes the fields configured with the special purposes according to the special purposes, the purposes of the residual available frequency domain resource indicated values can be flexibly designed, and rich application scenes can be expanded based on all the residual available frequency domain resource indicated values; and all available frequency domain resource indicated values can be fully utilized, and resource waste is avoided.
