[0002] In the Long Term Evolution (LTE) system, multi-point coordinated transmission technology is supported as an effective method to improve user data transmission rate and is continuously enhanced in subsequent versions of the LTE protocol.

[0003] In the process of New Radio (NR) standardization, similar multi-point cooperative transmission technology is called Transmitter Receiver Point (TRP) transmission. In the Rel-15 (Release-15) version, multi-TRP transmission only enhances the downlink transmission of Ultra Reliable Low Latency Communication (URLLC) and Enhanced Mobile BroadBand (EMBB) systems, and does not enhance the uplink transmission of URLLC and EMBB systems. Currently, the uplink transmission of URLLC in the Rel-16 version only supports a single TRP transmission scheme. The Rel-17 version has made it clear that multi-TRP (multi-TRP) enhancements will be made to the uplink PUSCH and PUCCH transmissions of URLLC.

[0004] When supporting sub-slot PUCCH repetitive transmission in a URLLC-based system, how to configure the transmission is a problem. For example, using a method similar to R15 / R16 to perform unified configuration using Radio Resource Control (RRC) signaling is less flexible.

[0047] As mentioned above, when the physical downlink control channel (PDCCH) of the sub-time slot is repeatedly transmitted in the URLLC system, how to configure the transmission is a problem. The PUCCH upload method in the prior art has low flexibility.

[0048] Currently, for the PUCCH transmission of URLLC in Rel-15, the following five PUCCH formats are supported, as listed in Table 1. The PUCCH in each time slot can only be repeatedly transmitted in units of time slots, and the number of repetitions is uniformly configured by RRC signaling, that is, formats 1, 3, and 4 can only use a unified number of repetitions, so the flexibility is low.

[0049] Refer to Table 1, which shows the PUCCH format supported by PUCCH transmission of URLLC of Rel-15 in the prior art.

[0050] Table 1

[0051] 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

[0052] For URLLC transmission of Rel-16, in order to reduce the transmission delay of uplink control information (UCI) and improve scheduling flexibility, it is proposed to use sub-slot as a unit for PUCCH transmission. For the time slot of ordinary cyclic prefix (CP), the length of sub-slot can be 2 symbols or 7 symbols, and for the time slot of extended CP, the length of sub-slot can be 2 symbols or 6 symbols. And the configuration of PUCCH resources must be within the sub-slot and cannot cross the sub-slot boundary. And PUCCH transmission based on sub-slot cannot be repeated.

[0053] For URLLC transmission of Rel-17, it has been proposed to enhance the PUCCH transmission of sub-slots, such as supporting repeated transmission of PUCCH of sub-slots, but the specific method of supporting repeated transmission has not yet been determined.

[0054] Combined with reference Figure 1 and Figure 2 , Figure 1 This is a timing diagram of uploading PUCCH using the first repetition type (Type A) in the prior art. Figure 2 This is a timing diagram of uploading PUCCH using the second repetition type (Type B) in the prior art.

[0055] like Figure 1 For the sub-slot PUCCH repetition transmission Type A shown, the transmission is performed in sub-slot units, which is similar to the PUCCH repetition transmission of R-15, except that the repetition unit is changed from slot to sub-slot. The time domain position of PUCCH in each sub-slot is exactly the same.

[0056] like Figure 2 As shown, for sub-slot PUCCH repetition transmission Type B, the transmission is performed in units of PUCCH format length, and the PUCCH repetition is continuously transmitted in adjacent symbols and may cross sub-slot boundaries.

[0057] When supporting sub-slot PUCCH repetitive transmission in a URLLC-based system, in order to configure the transmission, a method similar to R15 / R16 can be used for unified configuration using RRC signaling. However, the inventor of the present invention has found through research that in the prior art, a unified configuration method is used. Although this method has a small signaling overhead, it has low flexibility and is difficult to meet the diverse needs of different PUCCH formats.

[0058] In the embodiment of the present invention, by setting the base station to send repetition indication information for indicating the number of repetitions and the type of repetitions for uploading PUCCH to the UE, the UE can upload the PUCCH data using the number of repetitions and the type of repetitions authorized by the base station. And because the base station can flexibly configure the number of repetitions and the type of repetitions, compared with the unified configuration in the prior art, the solution of the embodiment of the present invention can effectively improve the flexibility of the number of repetitions and the type of repetitions for uploading PUCCH.

[0059] In order to make the above-mentioned objects, features and beneficial effects of the present invention more obvious and easy to understand, specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0060] Reference Figure 3 , Figure 3 1 is a flow chart of a PUCCH data uploading method in an embodiment of the present invention. The PUCCH data uploading method can be used on the terminal side, and can also include steps S31 to S32:

[0061] Step S31: receiving repetition indication information, where the repetition indication information is used to indicate the number of repetitions and the repetition type of uploading the PUCCH;

[0062] Step S32: Upload PUCCH data using the repetition number and repetition type according to the repetition indication information.

[0063] In the specific implementation of step S31, a variety of parameters are disclosed in the communication protocol for repeated transmission of PUCCH based on sub-slot of R15 / R16, such as PUCCH sub-slot length (subslotLengthForPUCCH-R16), etc. If the parameter is configured in the PUCCH configuration file (PUCCH-config), the repetition type and number of repetitions can be configured under RRC signaling.

[0064] In a specific application, the repetition type can be configured as M, such as Type A or Type B, represented by 1 bit. The number of repetitions can be configured as N, such as 2, 4, or 8, represented by 2-3 bits. M and N are positive integers.

[0065] Further, in a 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 using each PUCCH format.

[0066] Specifically, the PUCCH configuration file can be configured by the base station, and can be single or multiple, for example, 2. Each PUCCH configuration file includes one or more PUCCH formats. The base station can configure the number of repetitions and repetition types for each PUCCH. The number of repetitions and repetition types of different PUCCH formats can be the same or different.

[0067] In the embodiment of the present invention, the number of repetitions and the repetition type may be configured separately in each or each group of PUCCH formats in each PUCCH configuration file.

[0068] 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 that are not configured with the number of repetitions and the repetition type can be set not to be repeatedly transmitted.

[0069] Furthermore, the repetition indication information is received via RRC signaling.

[0070] In the embodiment of the present invention, by setting the repetition indication information to include each PUCCH format in the PUCCH configuration file, and the number of repetitions and the repetition type of the PUCCH transmitted using each PUCCH format, each PUCCH format can be configured separately, which is very flexible. It can be understood that the RRC configuration overhead is also large.

[0071] Furthermore, in a second specific implementation manner of an embodiment of the present invention, the repetition indication information may include one or more groups of PUCCH formats in a PUCCH configuration file, each group of PUCCH formats containing one or more PUCCH formats, and also including the number of repetitions and repetition types of PUCCH transmitted using each group of PUCCH formats; wherein 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 has the same number of repetitions and repetition type.

[0072] Specifically, by setting each group of PUCCH formats to include one or more PUCCH formats, and each group of PUCCH formats has the same number of repetitions and repetition types, the PUCCH formats can be grouped, and multiple PUCCH formats with the same number of repetitions and repetition types can be notified uniformly. Compared with notifying each PUCCH format individually, the signaling overhead can be reduced.

[0073] In an embodiment of the present invention, by setting the repetition indication information to include one or more groups of PUCCH formats in a PUCCH configuration file, each group of PUCCH formats contains one or more PUCCH formats, and the PUCCH formats can be grouped. Since each group of PUCCH formats has the same number of repetitions and repetition types, the number of repetitions and repetition types for each group of PUCCH formats are uniformly notified, thereby improving flexibility while reducing signaling overhead to a certain extent, thereby achieving a balance between high flexibility and low signaling overhead.

[0074] Further, the PUCCH format is divided into at least two groups according to whether the length is within a preset length range.

[0075] In a specific application of an embodiment of the present invention, the PUCCH format can be divided into two groups; the PUCCH formats with a length less than a preset length in the repetition indication information all use a first number of repetitions, and the PUCCH formats with a length greater than or equal to a preset length in the repetition indication information all use a second number of repetitions; wherein the first number of repetitions is greater than the second number of repetitions.

[0076] It should be pointed out that if the length of the PUCCH format is large, it is less likely to make errors during the transmission and reception process, or even if an error occurs, it is easier to correct the error successfully. In this case, a smaller second repetition number can be used; if the length of the PUCCH format is small, it is easier to make errors during the transmission and reception process, or it is more difficult to correct the error successfully. In this case, a larger first repetition number can be used.

[0077] In a specific application of the embodiment of the present invention, short PUCCHs, such as PUCCH-format0 and PUCCH-format2, can be grouped together to uniformly configure the number of repetitions and types; long PUCCHs, such as PUCCH-format1, PUCCH-format3 and PUCCH-format4, can be grouped together to uniformly configure the number of repetitions and types. This improves flexibility while reducing signaling overhead to a certain extent, achieving a balance between high flexibility and low signaling overhead.

[0078] Combined with reference Figure 4 and Figure 5 , Figure 4 This is a timing diagram of uploading a PUCCH using the first repetition type in the first embodiment of the present invention; Figure 5 This is the first timing diagram of uploading PUCCH using the second repetition type in an embodiment of the present invention.

[0079] like Figure 4It shows the timing diagram of PUCCH data upload when the number of symbols (nrofSymbols) configured in PUCCH repetition format 0 (PUCCH-format0) is 2, the sub-slot length (sub-slot length) is 7, and the configured repetition type is Type A, and the number of repetitions is 2.

[0080] like Figure 5 It shows the timing diagram of PUCCH data upload when the number of symbols configured for PUCCH repetition format 0 is 2, the sub-slot length is 7, and the configured repetition type is Type B and the number of repetitions is 2.

[0081] It should be noted that there may be a repetition gap between adjacent repeated uploads, that is, there may be a situation where the sub-slot repetition gap (Sub-slot-RepetitionGap) is greater than or equal to 1 symbol (Symbol).

[0082] In a third specific implementation manner of an embodiment of the present invention, before receiving the repetition indication information, the PUCCH data upload method may further include: receiving a preconfiguration table, the preconfiguration table including multiple rows of information, each row of information including the number of repetitions and the repetition type; wherein the repetition indication information includes the row number or index number in the preconfiguration table.

[0083] Specifically, the preconfigured table may include a large amount of format information and repeated information. By pre-providing the preconfigured table, it is equivalent to pre-providing a large amount of format information and repeated information, so that only a small amount of information (such as row number or index number) can be used to indicate complex information.

[0084] Refer to Table 2, which is a PUCCH pre-configuration table in an embodiment of the present invention.

[0085] Table 2

[0086]

[0087]

[0088] In a specific implementation, if the DCI indicates the first row, the corresponding PUCCH transmission uses Type A, and the number of repetitions is 2. If the DCI does not indicate a field, repeated transmission may be performed by default, or a preset row in the table (eg, the first row) may be used by default.

[0089] Furthermore, the number of repetition times may be N, and the number of repetition types may be M, where M and N are positive integers; the row number or index number may be bits represent.

[0090] Specifically, as shown in Table 2, M=2, N=3, the row number or index number is bits represent.

[0091] Furthermore, the preconfiguration table may be received via RRC signaling; and / or the repetition indication information may be received via DCI signaling.

[0092] In an embodiment of the present invention, the preconfiguration table is set to be received through RRC signaling; and / or the repetition indication information is received through DCI signaling. The table can be sent by RRC signaling with a lower sending frequency, and the row number can be sent by DCI signaling with a higher sending frequency and more valuable, thereby further improving flexibility and reducing signaling overhead, thereby achieving a better balance between high flexibility and low signaling overhead.

[0093] Combined with reference Figure 6 and Figure 7 , Figure 6 This is a timing diagram of uploading a PUCCH using the second first repetition type in an embodiment of the present invention; Figure 7 This is a second timing diagram of uploading PUCCH using the second repetition type in an embodiment of the present invention.

[0094] like Figure 6 The timing diagram of PUCCH data upload is shown when the DCI indicates the third row, that is, the number of symbols corresponding to the PUCCH format indicated in the DCI is 1, and the sub-slot length is 2.

[0095] like Figure 7 The timing diagram of PUCCH data upload is shown when the DCI indicates the second row, that is, the number of symbols corresponding to the PUCCH format indicated in the DCI is 7, and the sub-slot length is 7.

[0096] In an embodiment of the present invention, before receiving the repetition indication information, a step of sending and receiving a preconfiguration table may be further provided, wherein the preconfiguration table includes multiple lines of information, each line of information includes the number of repetitions and the type of repetition; wherein the repetition indication information includes a line number or an index number in the preconfiguration table. By adopting the solution of the embodiment of the present invention, a large amount of format information and repetition information can be provided in advance by pre-providing a preconfiguration table, so that complex information can be indicated by only a small amount of information (line number or index number), thereby further reducing signaling overhead.

[0097] Further, the PUCCH data may be uploaded in units of sub-time slots; before receiving the repetition indication information, the PUCCH data uploading method may further include: receiving repetition gap indication information.

[0098] It should be noted that in the prior art, there is a situation where there is no interval between adjacent repeated transmissions. Figure 2 Taking the timing diagram of PUCCH data upload in the prior art as an example, the last symbol of the previous repeated transmission is adjacent to the first symbol of the next repeated transmission.

[0099] After further research, the inventors of the present invention found that when the sub-slot PUCCH is repeatedly transmitted and combined with multi-TRP, the UE uses different beams to upload PUCCH data. If the PUCCH transmission is continuous, then when the UE switches beams on different repeated transmissions, there is no protection time between adjacent repetitions, which may cause greater pressure on the UE transmitter and radio frequency.

[0100] In the specific implementation, considering that PUCCH repetition is bound to the multi-TRP function, if the sub-slot length (sub-slot length) or the PUCCH resource length (resource length) is short, it may cause the TRP switching to be too frequent. Therefore, the repetition gap indication information (Sub-slot-RepetitionGap) field can be introduced in the PUCCH configuration file.

[0101] More specifically, the size of the repetition gap indication information may be set to {0, 1, .. N}.

[0102] Taking Type A as an example, the length of the repetition gap indication information may be N*subslotLength.

[0103] Taking Type B as an example, the length of the repetition gap indication information may be N*nrofSymbols, or N*pucchresource length.

[0104] Furthermore, when the size of the repetition gap indication information is 0, it can be used to indicate that no repetition gap is introduced.

[0105] In an embodiment of the present invention, by introducing repetition gap indication information, protection time can be left between repeated transmissions of PUCCH corresponding to different beams for beam switching, thereby better meeting the actual system requirements of multi-TRP transmission.

[0106] Furthermore, the repetition gap indication information may be sent when the repetition type is Type B; or; the repetition gap indication information is sent when the repetition type is Type A and the length of the PUCCH format is equal to the length of the sub-time slot.

[0107] In the embodiment of the present invention, since there is an interval between adjacent PUCCH repetition transmissions when the repetition type is Type A and the length of the PUCCH format is greater than the length of the sub-time slot, it is theoretically unnecessary to set the repetition gap indication information. By setting the situation of sending the repetition gap indication information, configuration can be performed according to specific needs and when there is a need.

[0108] It should be noted that in the embodiment of the present invention, if the UE has clearly indicated that it does not want to configure a repetition gap, that is, it is not necessary to configure an interval between adjacent PUCCH repetition transmissions, the base station can determine whether to comply with the UE's expectations based on specific circumstances.

[0109] Reference Figure 8 , Figure 8 This is a third timing diagram of uploading PUCCH using the first repetition type in an embodiment of the present invention.

[0110] like Figure 8 It shows a timing diagram of PUCCH data upload when the DCI indicates the second row, 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-RepetitionGap) = 1.

[0111] In the embodiment of the present invention, by setting the base station to send repetition indication information for indicating the number of repetitions and the type of repetitions for uploading PUCCH to the UE, the UE can upload the PUCCH data using the number of repetitions and the type of repetitions authorized by the base station. And because the base station can flexibly configure the number of repetitions and the type of repetitions, compared with the unified configuration in the prior art, the solution of the embodiment of the present invention can effectively improve the flexibility of the number of repetitions and the type of repetitions for uploading PUCCH.

[0112] In an embodiment of the present invention, a PUCCH data upload method is also disclosed. The PUCCH data upload method can be used on the base station side and may also include: configuring repetition indication information, wherein the repetition indication information is used to indicate the number of repetitions and the repetition type of uploading the PUCCH; sending the repetition indication information so that the terminal uploads the PUCCH data according to the repetition indication information using the repetition number and the repetition type.

[0113] Furthermore, configuring the repetition indication information includes: determining a PUCCH configuration file, and determining each PUCCH format in each PUCCH configuration file; and configuring the number of repetitions and the repetition type of the PUCCH transmitted using each PUCCH format.

[0114] Furthermore, configuring the repetition indication information includes: determining a PUCCH profile, and determining one or more groups of PUCCH formats in each PUCCH profile, each group of PUCCH formats containing one or more PUCCH formats; configuring the number of repetitions and repetition type of PUCCH transmitted using each group of PUCCH formats; wherein the PUCCH formats are divided into at least two groups according to whether their lengths are within a preset length range, and each group of PUCCH formats has the same number of repetitions and repetition type.

[0115] Furthermore, the PUCCH format can be divided into two groups; PUCCH formats with a length less than a preset length in the repetition indication information all use a first number of repetitions, and PUCCH formats with a length greater than or equal to a preset length in the repetition indication information all use a second number of repetitions; wherein the first number of repetitions is greater than the second number of repetitions.

[0116] Furthermore, the repetition indication information is sent via RRC signaling.

[0117] Furthermore, before sending the repetition indication information, the PUCCH data upload method may also include: sending a preconfiguration table, the preconfiguration table including multiple rows of information, each row of information including the number of repetitions and the repetition type; wherein the repetition indication information includes the row number or index number in the preconfiguration table.
