Detailed Description
As described above, when a Physical Downlink Control Channel (PDCCH) supporting a sub-slot in the URLLC-based system is transmitted repeatedly, how to configure the transmission is a problem. The PUCCH uploading method in the prior art is low in flexibility.
Currently, for PUCCH transmission of the URLLC of Rel-15, the following 5 PUCCH formats are supported, as listed in table 1. The PUCCH in each slot can only be repeatedly transmitted in a slot unit, and the number of repetitions is uniformly configured by RRC signaling, that is, formats (formats) 1,3,4 can only use a uniform number of repetitions, and thus flexibility is low.
Referring to table 1, table 1 shows PUCCH formats supported by PUCCH transmission of URLLC of Rel-15 in the related art.
TABLE 1
Length #of RBs #of bits Repetition
Format
0 Short 1 1~2 N/A
Format
1 Long 1 1~2 Inter-slot
Format 2 Short 1~16 >2 N/A
Format 3 Long 1~16 >2 Inter-slot
Format
4 Long 1 >2 Inter-slot
For the URLLC transmission of Rel-16, in order to reduce the transmission delay of Uplink Control Information (UCI) and improve scheduling flexibility, it is proposed that PUCCH transmission may be performed using sub-slot as a unit. The sub-slot may have a length of 2 symbols or 7 symbols for a slot of a normal Cyclic Prefix (CP), and may have a length of 2 symbols or 6 symbols for a slot of an extended CP. And the configuration of the PUCCH resource must be within the sub-slot and cannot cross the sub-slot boundary. And sub-slot based PUCCH transmission may not be transmitted repeatedly.
For Rel-17 URLLC transmission, enhancement of sub-slot PUCCH transmission has been proposed at present, such as supporting sub-slot PUCCH repetition transmission, but how to support repetition transmission has not been determined.
Referring to fig. 1 and fig. 2 in combination, fig. 1 is a timing diagram of a PUCCH uploaded by using a first repetition Type (Type a) in the prior art, and fig. 2 is a timing diagram of a PUCCH uploaded by using a second repetition Type (Type B) in the prior art.
For sub-slot PUCCH repetition transmission Type a as shown in fig. 1, transmission is performed in units of sub-slots, similar to PUCCH repetition transmission of R-15, except that the repetition unit is changed from slot to sub-slot. The time domain position of the PUCCH within each sub-slot is identical.
For sub-slot PUCCH repetition transmission Type B as shown in fig. 2, transmission is performed in units of PUCCH format length, and PUCCH repetition is continuously transmitted within adjacent symbols and may cross sub-slot boundaries.
When the sub-slot-based PUCCH repeated transmission is supported in the URLLC system, in order to configure the transmission, the unified configuration can be carried out by using RRC signaling in a manner similar to R15/R16. However, the inventor of the present invention has found, through research, that in the prior art, a unified configuration method is adopted, which has low flexibility although the signaling overhead is small, and is difficult to meet the requirement of diversification of different PUCCH formats.
In the embodiment of the invention, the base station is set to send the repetition indication information for indicating the repetition times and the repetition types of the uplink PUCCH to the UE, so that the UE can adopt the repetition times and the repetition types authorized by the base station to uplink when uplink PUCCH data. And because the base station can flexibly configure the repetition times and the repetition types, compared with the uniform configuration in the prior art, the scheme of the embodiment of the invention can effectively improve the flexibility of the repetition times and the repetition types of the uplink PUCCH.
In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in detail below.
Referring to fig. 3, fig. 3 is a flowchart of a PUCCH data uploading method in an embodiment of the present invention. The PUCCH data upload method may be used at a terminal side, and may further include steps S31 to S32:
step S31: receiving repetition indication information, wherein the repetition indication information is used for indicating the repetition times and the repetition types of the uploading PUCCH;
step S32: and uploading PUCCH data by adopting the repetition times and the repetition types according to the repetition indication information.
In the specific implementation of step S31, various parameters are disclosed in the communication protocol of PUCCH repetition transmission based on sub-slot of R15/R16, for example, the parameters may include PUCCH subslot length (subslot length for PUCCH-R16). If the parameter is configured in a PUCCH configuration file (PUCCH-config), the repetition type and the number of repetitions may be configured under RRC signaling.
In a specific application, the repetition types can be configured into M types, and for example, the repetition types can be Type a or Type B, and are represented by 1 bit. The number of repetitions may be configured to be N, and may be 2,4,8, for example, and expressed by 2-3 bits. Wherein M, N is a positive integer.
Further, in the first specific implementation manner of the embodiment of the present invention, the repetition indication information may include each PUCCH format in the PUCCH configuration file, and the number of repetitions and the repetition type of the PUCCH transmitted in each PUCCH format.
Specifically, the PUCCH configuration file may be configured by the base station, and may be single or multiple, for example, 2, each PUCCH configuration file includes one or more PUCCH formats, the base station may configure a respective repetition number and repetition type for each PUCCH, and the repetition number and repetition type of different PUCCH formats may be the same or different.
In the embodiment of the present invention, the number of repetitions and the repetition type may be configured separately in the PUCCH format of each or each group in each PUCCH configuration file,
it should be noted that, if the number of repetitions and the repetition type are not configured in one or more PUCCH formats in any PUCCH configuration file, the PUCCH formats without the number of repetitions and the repetition type may be set not to perform repeated transmission.
Further, the repetition indication information is received through RRC signaling.
In the embodiment of the invention, by setting the repetition indication information to comprise each PUCCH format in the PUCCH configuration file, and the repetition times and the repetition types of the PUCCHs transmitted by adopting each PUCCH format, each PUCCH format can be configured independently, and the flexibility is very high. It can be appreciated that the RRC configuration overhead is also large.
Further, in a second specific implementation manner of the embodiment of the present invention, the repetition indication information may include one or more sets of PUCCH formats in a PUCCH configuration file, where each set of PUCCH formats includes one or more PUCCH formats, and further includes a repetition number and a repetition type of a PUCCH transmitted using each set of PUCCH formats; the PUCCH formats are divided into at least two groups according to whether the length is within a preset length range, and each group of PUCCH formats have the same repetition times and repetition types.
Specifically, by setting each group of PUCCH formats to contain one or more PUCCH formats, each group of PUCCH formats has the same repetition number and repetition type, the PUCCH formats can be grouped, and a plurality of PUCCH formats having the same repetition number and repetition type can be uniformly notified, which can reduce signaling overhead compared to individually notifying based on each PUCCH format.
In the embodiment of the invention, the repetition indication information comprises one or more groups of PUCCH formats in the PUCCH configuration file, each group of PUCCH formats comprises one or more PUCCH formats, the PUCCH formats can be grouped, and because each group of PUCCH formats has the same repetition times and repetition types, the repetition times and the repetition types of each group of PUCCH formats are uniformly notified, so that the flexibility is improved, the signaling overhead is reduced to a certain extent, and the balance between high flexibility and low signaling overhead is achieved.
Further, the PUCCH formats are divided into at least two groups according to whether the length is within a preset length range.
In a specific application of the embodiment of the present invention, the PUCCH formats may be divided into two groups; the PUCCH formats with the length smaller than the preset length in the repetition indication information all adopt a first repetition number, and the PUCCH formats with the length larger than or equal to the preset length in the repetition indication information all adopt a second repetition number; wherein the first number of repetitions is greater than the second number of repetitions.
It should be noted that if the length of the PUCCH format is large, an error is not easily generated in the transceiving process, or even if an error occurs, the error is more easily corrected successfully, and a smaller second repetition number may be used at this time; if the length of the PUCCH format is small, errors are prone to occur during transceiving, or it is more difficult for error correction to succeed, and a larger first repetition number may be used.
In a specific application of the embodiment of the present invention, short PUCCHs, such as PUCCH-format0 and PUCCH-format2, may be grouped into one group, and the number and type of repetitions may be configured in a unified manner; the long PUCCHs such as PUCCH-format1, PUCCH-format3 and PUCCH-format4 are grouped into a group, and the number and type of repetition are configured uniformly. Therefore, the flexibility is improved, meanwhile, the signaling overhead is reduced to a certain degree, and the balance between high flexibility and low signaling overhead is achieved.
With combined reference to fig. 4 and fig. 5, fig. 4 is a timing diagram of a first PUCCH uploading using a first repetition type in the embodiment of the present invention; fig. 5 is a timing diagram of a first PUCCH uploaded by using a second repetition type in the embodiment of the present invention.
As shown in fig. 4, a timing diagram of PUCCH data upload when the PUCCH repetition format 0(PUCCH-format0) is configured with symbol number (nrofSymbols) of 2 and sub-slot length (sub-slot length) of 7, and the configured repetition Type is Type a and the repetition number is 2 is shown.
As shown in fig. 5, when the number of symbols of the PUCCH repetition format0 configuration is 2 and the sub-slot length is 7, and the configured repetition Type is Type B, the timing diagram of PUCCH data upload with repetition number of 2 is shown.
It should be noted that, between adjacent repeated uploads, there may also be a repetition interval, i.e. there may be a Sub-slot repetition interval (Sub-slot-repetition gap) greater than or equal to 1 Symbol (Symbol).
In a third specific implementation manner of the embodiment of the present invention, before receiving the repetition indication information, the PUCCH data uploading method may further include: receiving a preconfigured table, the preconfigured table comprising a plurality of rows of information, each row of information comprising a number of repetitions and a repetition type; wherein the repetition indication information comprises a row sequence number or an index number in the preconfigured table.
Specifically, the preconfigured table may include a large amount of format information and repeated information, and by providing the preconfigured table in advance, it is equivalent to providing a large amount of format information and repeated information in advance, so that only a small amount of information (such as a row number or an index number) is used to indicate complex information.
Referring to table 2, table 2 is a PUCCH preconfiguration table in the embodiment of the present invention.
TABLE 2

Figure BDA0002717744920000111
In a specific implementation, if the DCI indicates the first row, the corresponding PUCCH transmission is Type a and the number of repetitions is 2. If the DCI does not have the indicated field, the repeated transmission may be avoided by default, or a predetermined row (e.g., the first row) in the table may be used by default.
Further, the number of the repetition times may be N, the number of the repetition types may be M, wherein M, N is a positive integer; the line sequence number or index number adopts

A single bit representation.
Specifically, if M is 2 and N is 3 as shown in table 2, the row number or index number is adopted
Figure BDA0002717744920000113
Figure BDA0002717744920000114
A single bit representation.
Still further, the pre-configured table may be received through RRC signaling; and/or the repetition indication information may be received through DCI signaling.
In the embodiment of the invention, the pre-configuration table is received through RRC signaling; and/or, the repetition indication information is received through DCI signaling, and an RRC signaling transmission table with a lower transmission frequency may be used, and a DCI signaling transmission row number with a higher transmission frequency and a more precious value is used, so as to further improve flexibility and reduce signaling overhead, and achieve a better balance between high flexibility and low signaling overhead.
With combined reference to fig. 6 and fig. 7, fig. 6 is a timing diagram of a second PUCCH uploaded by using a first repetition type in this embodiment of the present invention; fig. 7 is a timing diagram of a second PUCCH uploading using a second repetition type in this embodiment of the present invention.
Fig. 6 shows a timing diagram of PUCCH data upload when DCI indicates row 3, that is, the number of symbols corresponding to the PUCCH format indicated in DCI is 1, and the sub-slot length is 2.
Fig. 7 shows a timing diagram of PUCCH data upload when DCI indicates row 2, that is, the number of symbols corresponding to the PUCCH format indicated in the DCI is 7, and the sub-slot length is 7.
In the embodiment of the present invention, before receiving the repetition indication information, a step of transceiving a preconfigured table may be further provided, where the preconfigured table includes a plurality of rows of information, and each row of information includes a repetition number and a repetition type; wherein the repetition indication information comprises a row sequence number or an index number in the preconfigured table. By adopting the scheme of the embodiment of the invention, a large amount of format information and repeated information can be provided in advance by providing the pre-configuration table in advance, so that the complex information can be indicated by only adopting a small amount of information (row serial numbers or index numbers), thereby further reducing the signaling overhead.
Further, the PUCCH data may be uploaded in a unit of a sub-slot; before receiving the repetition indication information, the PUCCH data uploading method may further include: repetition gap indication information is received.
It is noted that in the prior art, there are situations where there is no gap in adjacent repeated transmissions. Specifically, taking the timing diagram of PUCCH data uploading in the prior art shown in fig. 2 as an example, the last symbol of the previous repeated transmission is adjacent to the first symbol of the next repeated transmission.
The inventor of the present invention further researches and discovers that when sub-slot PUCCH is repeatedly transmitted and combined with multi-TRP, the UE uploads PUCCH data using different beams (beams), and if PUCCH transmission is continuous, then when the UE performs beam switching on different repeated transmissions, there is no guard time between adjacent repetitions, and thus, there may be a large pressure on the UE transmitting end and the radio frequency.
In a specific implementation, considering that PUCCH repetition is tied to multi-TRP function, if Sub-slot length (Sub-slot length) or PUCCH resource length (resource length) is short, TRP switching may be too frequent, so a repetition gap indication information (Sub-slot-repetition gap) field may be introduced in the PUCCH profile.
More specifically, the size of the repetition gap indication information may be set to {0,1,. N }.
Taking Type a as an example, the length of the repetition gap indication information may be N × substlotlength.
Taking Type B as an example, the length of the repetition gap indication information may be N × nrofSymbols or N × pucch resource length.
Further, when the size of the repetition gap indication information is 0, it can be used to indicate that no repetition gap is introduced.
In the embodiment of the invention, by introducing the repetition gap indication information, the beam switching can be carried out by reserving guard time between the repeated transmission of PUCCHs corresponding to different beams, thereby further meeting the actual system requirement of multi-TRP transmission.
Further, the repetition gap indication information may be transmitted when the repetition Type is Type B; or; the repetition gap indication information is transmitted when the repetition Type is Type a and the length of the PUCCH format is equal to the length of the sub-slot.
In the embodiment of the present invention, when the repetition Type is Type a and the length of the PUCCH format is greater than the length of the sub-slot, there is an interval between adjacent PUCCH repetition transmissions, and thus, it is theoretically unnecessary to set repetition gap indication information. By setting the condition of sending the repeated gap indication information, the configuration can be carried out under the condition of having requirements according to specific requirements.
It should be noted that, in the embodiment of the present invention, if the UE has explicitly indicated that it is not desirable to configure the repetition gap, that is, it is not necessary to configure the interval between the adjacent PUCCH repetition transmissions, the base station may determine whether to comply with the UE's expectations according to specific situations.
Referring to fig. 8, fig. 8 is a timing diagram of a third PUCCH uploaded by using a first repetition type in this embodiment of the present invention.
Fig. 8 shows a timing diagram of PUCCH data upload when DCI indicates row 2, that is, when the number of symbols corresponding to the PUCCH format indicated in the DCI is 2 and the Sub-slot length is 7, and the repetition gap indication information (Sub-slot-repetition gap) is 1.
In the embodiment of the invention, the base station is set to send the repetition indication information for indicating the repetition times and the repetition types of the uplink PUCCH to the UE, so that the UE can adopt the repetition times and the repetition types authorized by the base station to uplink when uplink PUCCH data. And because the base station can flexibly configure the repetition times and the repetition types, compared with the uniform configuration in the prior art, the scheme of the embodiment of the invention can effectively improve the flexibility of the repetition times and the repetition types of the uplink PUCCH.
In the embodiment of the present invention, a PUCCH data upload method is also disclosed, and the PUCCH data upload method may be used on the base station side, and may further include: configuring repetition indication information, wherein the repetition indication information is used for indicating the repetition times and the repetition types of the uploading PUCCH; and sending the repetition indication information to enable the terminal to upload PUCCH data by adopting the repetition times and the repetition types according to the repetition indication information.
Further, configuring the repetition indication information includes: determining PUCCH configuration files and determining various PUCCH formats in each PUCCH configuration file; configuring the number of repetitions and the repetition type of the PUCCH transmitted with each PUCCH format.
