The transmission method provided by the embodiment of the application is described in detail below by some embodiments and application scenarios thereof with reference to the accompanying drawings.

The embodiment of the present application provides a transmission method, as shown in fig. 2, where the transmission method provided in the embodiment of the present application may include the following steps 201 and 202:

step 201: the user equipment UE obtains the first information.

Optionally, in an embodiment of the present application, the first information is used to indicate at least one of:

whether to perform common PUCCH repeated transmission;

parameter related information of common PUCCH repeated transmission;

effective time offset for common PUCCH repeat transmission.

Optionally, in this embodiment of the present application, the first information is information sent by a network side device received by the UE or preconfigured information acquired by the UE.

Optionally, in the embodiment of the present application, the first information may be sent by the network side device in a dynamic manner, a static manner, or a semi-static manner, that is, the common PUCCH repeated transmission of the UE may be dynamically or semi-statically indicated by the network side device.

Optionally, in the embodiment of the present application, the dynamic or semi-static indication of the common PUCCH repeated transmission is protocol-contracted or preconfigured.

Illustratively, if the common PUCCH repeat transmission is determined by downlink control information (Downlink Control Information, DCI) or non-radio resource control (Radio Resource Control, RRC) signaling within the downlink physical downlink shared channel (Physical Downlink Shared Channel, PDSCH), then the common PUCCH repeat transmission is dynamically indicated; if the common PUCCH retransmission is determined by RRC signaling (e.g. system message) and/or medium access control-control unit MAC-CE, then the common PUCCH retransmission is indicated semi-statically.

Optionally, in the embodiment of the present application, the parameter related information of the common PUCCH retransmission may be configured, agreed, or preconfigured on the network side.

Optionally, the effective time offset of the common PUCCH retransmission may be configured, agreed, or preconfigured on the network side.

Optionally, in an embodiment of the present application, the parameter related information of the common PUCCH retransmission includes at least one of the following:

number of common PUCCH repeated transmissions;

a common PUCCH format;

a common PUCCH cyclic shift index set;

a start symbol of the common PUCCH repeated transmission;

the number of symbols of the common PUCCH repeated transmission;

PRB offset of common PUCCH repeated transmission;

the common PUCCH repeats the transmitted termination symbols.

For example, the number of common PUCCH repeated transmissions may be 1, 2,4, or 8, and the number of common PUCCH repeated transmissions may also be other repeated transmission numbers, which is not limited in the embodiment of the present application.

For example, the common PUCCH format may be format 0 or format 1, and the common PUCCH format may also be another format, which is not limited in the embodiment of the present application.

For example, the number of symbols of the common PUCCH retransmission may be 2,4, 10, or 14, and the number of symbols of the common PUCCH retransmission may also be other number of symbols, which is not limited in the embodiment of the present application.

For example, the PRB offset of the common PUCCH retransmission may be 0,2,3, or 4, and the number of symbols of the common PUCCH retransmission may also be other symbol numbers, which is not limited in the embodiment of the present application.

Note that, in the case where the sum of the product of the start symbol of the common PUCCH repeated transmission and the number of symbols of the common PUCCH repeated transmission and the number of repetitions is greater than 14, the common PUCCH repeated transmission performed is inter-slot transmission; in the case where the sum of the start symbol of the common PUCCH repeated transmission and the number of symbols of the common PUCCH repeated transmission is less than or equal to 14, the common PUCCH repeated transmission is an intra-slot transmission.

It will be appreciated that in the case where one slot corresponds to 14 OFDM symbols, if the sum of the product of the start symbol and the number of symbols of the common PUCCH repeated transmission and the number of repetitions exceeds the number of symbols 14 of one slot, repeated transmission in a plurality of slots is required.

Step 202: and the User Equipment (UE) executes related actions of common PUCCH repeated transmission according to the first information.

Wherein, the public PUCCH is the PUCCH transmitted on the public transmission resource.

Optionally, in the embodiment of the present application, the common transmission resource may be a common PUCCH transmission resource (common PUCCH resource), and the PUCCH on the common PUCCH resource may be a common PUCCH (common PUCCH).

Alternatively, in the embodiment of the present application, the above-mentioned common transmission resource may include a PUCCH resource commonly configured by multiple users or a common PUCCH resource configured by each serving cell (serving cell), where the common PUCCH resource may be used by the UE before configuring the dedicated PUCCH resource (dedicated PUCCH resource).

It is appreciated that in the case where the UE is not configured (i.e., dedicate PUCCH resource), the UE may transmit PUCCH on the common PUCCH resource.

Optionally, in an embodiment of the present application, the common PUCCH repeated transmission may include intra-slot repetition (intra-slot repetition) and/or inter-slot repetition (inter-slot repetition). That is, the above-described common PUCCH repeated transmission supports at least one of intra-slot repetition and inter-slot repetition.

For intra-slot repetition, all PUCCH repetitions need to be transmitted in one slot, and the start symbol may be indicated by First symbol, and Number of symbols indicates the number of symbols occupied by each repetition. For inter-slot transmission, each repetition occupies one slot, each slot using the same First symbol and Number of symbols.

Optionally, in an embodiment of the present application, the common PUCCH is a PUCCH of a target PUCCH format.

Alternatively, the target format may include at least one of PUCCH format 0 and PUCCH format 1. That is, the above-described common PUCCH repeated transmission supports common PUCCH repeated transmission of a partial PUCCH format, for example, common PUCCH repeated transmission supporting PUCCH format 0 and PUCCH format 1.

Alternatively, in the embodiment of the present application, the UE may determine, according to the first information, that PUCCH retransmission is performed on the common transmission resource, or that PUCCH retransmission is not performed on the common transmission resource.

Alternatively, no PUCCH repeated transmission on the common transmission resource refers to the UE performing a legacy PUCCH (legacy PUCCH) transmission on the common transmission resource.

For example, in the case where the first indication information indicates that the common PUCCH repetition transmission is performed, the UE may perform PUCCH repetition transmission on the common PUCCH resource, and in the case where the first indication information indicates that the common PUCCH repetition transmission is not performed, the UE performs legacy PUCCH transmission, i.e. non-repetition transmission, on the common transmission resource.

Alternatively, in the embodiment of the present application, the UE may determine parameter related information of the common PUCCH repeated transmission according to the first information, and perform the common PUCCH repeated transmission according to the parameter related information of the common PUCCH repeated transmission.

Optionally, in the embodiment of the present application, the UE may determine an effective time offset of the common PUCCH retransmission according to the first information, then determine an effective time of the common PUCCH retransmission according to the effective time offset, and perform the common PUCCH retransmission at the effective time.

According to the transmission method provided by the embodiment of the application, the UE can acquire the first information and execute the related action of the common PUCCH repeated transmission according to the first information. Since the first information includes at least one of the first indication information for indicating whether to perform the common PUCCH repeated transmission, the parameter related information for indicating the common PUCCH repeated transmission, and the first offset for determining the effective time of the common PUCCH repeated transmission, the UE may perform the repeated transmission of the PUCCH on the common transmission resource according to the first information, so that a larger uplink coverage and better transmission performance may be achieved through the repeated transmission, and the transmission efficiency and the transmission reliability of the PUCCH transmitted on the common transmission resource may be improved.

Optionally, in an embodiment of the present application, the first information is carried in at least one of the following:

a system message;

PDSCH corresponding to common PUCCH;

scheduling Downlink Control Information (DCI) of a Physical Downlink Shared Channel (PDSCH) corresponding to a public PUCCH;

PDSCH carrying the first message;

scheduling DCI corresponding to PDSCH carrying the first message;

the first message may also be other messages, which is not limited in this embodiment of the present application.

Optionally, the system message is a system broadcast message of a Non-terrestrial communication network (Non-Terrestrial Networks, NTN), or a system broadcast message of a terrestrial communication network (Terrestrial Networks, TN), and the system message may also be other messages, which is not limited in this embodiment of the present application.

Optionally, the PDSCH corresponding to the common PUCCH may be a PDSCH that the network side device sends to the UE before the UE sends the common PUCCH.

For example, for common PUCCH repeated transmission of Msg4 hybrid retransmission feedback (Msg 4 HARQ feedback), the first information described above may be carried within the PDSCH carrying Msg 4.

Optionally, the DCI of the PDSCH corresponding to the common PUCCH may be the scheduling DCI of the PDSCH sent by the network side device to the UE before the UE sends the common PUCCH.

For example, for common PUCCH repeated transmission of Msg4 hybrid retransmission feedback, the first information described above may be carried in DCI scheduling PDSCH corresponding to PUCCH.

It may be appreciated that the first information carried in the system message, PDSCH, or DCI may be one or more bits of information. The one or more bit information may indicate whether to perform a common PUCCH retransmission and/or parameter related information of the common PUCCH retransmission and/or an effective time offset of the common PUCCH retransmission.

Alternatively, the four-step random access response message may be at least one of Msg2 and Msg4, and the two-step random access response message may be MsgB. Illustratively, the first message may include: at least one of Msg2, msg4 and MsgB may be other messages, which is not limited in the embodiment of the present application.

For example, for the common PUCCH repeated transmission of the HARQ feedback of any one PDSCH before RRC establishment, the first information may be carried in the PDSCH of Msg2 and/or Msg4 to indicate the common PUCCH repeated transmission of the UE.

For example, for the common PUCCH repeated transmission of the HARQ feedback of any one PDSCH before RRC establishment, the first information may be carried in the DCI scheduling the PDSCH of Msg2 and/or Msg4 to indicate the common PUCCH repeated transmission of the UE.

For example, for the common PUCCH repeated transmission of the HARQ feedback of any PDSCH before RRC establishment, first information may be carried in the PDSCH of the MsgB to indicate the common PUCCH repeated transmission of the UE.

For example, for the common PUCCH repeated transmission of the HARQ feedback of any PDSCH before RRC establishment, the first information may be carried in the DCI of the PDSCH of the scheduled MsgB to indicate the common PUCCH repeated transmission of the UE.

In this way, the common PUCCH retransmission of the UE is indicated by the PDSCH of the random access response message Msg2, msg4, msg b or the DCI scheduling the PDSCH of Msg2, msg4, msg b without resorting to other messages or signaling, thereby enabling saving of system signaling overhead.

Optionally, in an embodiment of the present application, the priority of the first information is agreed by a protocol, predefined, or configured by a network side device.

Optionally, in an embodiment of the present application, the priority of the first information is indicated by third indication information; the third indication information is carried in at least one of the following:

a system message;

PDSCH carrying the first message;

scheduling DCI corresponding to PDSCH carrying the first message;

wherein the first message includes at least one of a four-step random access response message and a two-step random access response message.

For example, the network side device may indicate the priority of the first information carried in the different messages or signaling. For example, the network-side device may configure the respective priorities for the different messages or signaling. For example, a higher priority is configured for PDSCH and a lower priority is configured for system messages such that the priority of the first message carried by PDSCH is higher than the priority of the first message carried by system messages.

Optionally, in this embodiment of the present application, the priority of the first information carried in the PDSCH or the scheduling DCI is higher than the priority of the first information carried in the system message.

For example, in the case of scheduling the first information carried in DCI of PDSCH of Msg2 and/or Msg4, the priority of the first information is higher than in the case of carrying the first information in system message.

It can be understood that the first information carried in DCI for scheduling PDSCH of Msg2 and/or Msg4, that is, the public PUCCH retransmission of UE is dynamically indicated by the network side device, and the first information carried in the system message, that is, the public PUCCH retransmission of UE is semi-statically indicated by the network side device, where the priority of the dynamically indicated public PUCCH retransmission is higher than that of the semi-statically indicated public PUCCH retransmission.

Optionally, in an embodiment of the present application, the first information includes at least one of:

the first indication information is used for indicating whether the common PUCCH repeated transmission is carried out or not;

the second indication information is used for indicating parameter related information of common PUCCH repeated transmission;

and the first offset is used for determining the effective time of the common PUCCH repeated transmission.

Optionally, the first indication information and the second indication information may be carried in a PDSCH corresponding to the common PUCCH, or carried in a DCI for scheduling a PDSCH corresponding to the common PUCCH, or carried in a PDSCH carrying Msg2/4/B, or carried in a PDSCH scheduling a PDSCH carrying Msg 2/4/B.

Alternatively, the first offset may be preconfigured, agreed upon, or indicated by the network side device.

Alternatively, the first offset may be a time domain offset.

Optionally, the first offset is determined by at least one of:

PUCCH format;

UE capability information.

For example, the first offsets corresponding to different PUCCH formats may be the same or different.

It is understood that the above-described PUCCH format refers to a PUCCH format of a PUCCH on a common transmission resource, i.e., a PUCCH format of a common PUCCH.

Optionally, in an embodiment of the present application, the second indication information is used to indicate at least one of:

parameter related information of common PUCCH repeated transmission;

first index information;

the common PUCCH repetition transmission number and the second index information.

Alternatively, in the case where the second indication information is used to indicate the first index information, the second indication information may be a pucch-resource common parameter or a newly configured parameter.

The newly configured parameter may be, for example, pucch-ResourceCommon-repetition.

For example, the network side device may indicate index information of the common PUCCH resource set table through the PUCCH-resource common parameter in the PUCCH-ConfigCommon parameter.

Illustratively, the above-described pucch-ResourceCommon parameter may include 4 bits (bits), indicating indices 0-15; alternatively, the pucch-ResourceCommon parameter described above may be bit-extended, for example, to 6 bits, indicating indices 0-64; or, the pucch-ResourceCommon parameter may be spliced with other parameters to obtain a spliced bit. The bits of the PUCCH-resource common parameter may specifically be determined according to the number of rows of the common PUCCH resource set table, which is not limited in the embodiment of the present application.

It should be noted that one PUCCH-resource common represents one row of parameter information in the common PUCCH resource set table, and the one row of parameter information represents a set of parameter information for common PUCCH retransmission.

According to the transmission method provided by the embodiment of the application, the second indication information can comprise at least one of the following indication modes for indicating the common PUCCH repeated transmission parameters, namely, directly indicating the relevant parameter information of the PUCCH repeated transmission, and indirectly indicating the relevant parameter information of the PUCCH repeated transmission through the table index, so that the reliability of the PUCCH transmission is improved.

Optionally, in the embodiment of the present application, in a case where the second indication information is used to indicate the first index information, the parameter related information of the common PUCCH repeated transmission includes first parameter information determined from a common PUCCH resource set table (PUCCH-resource common);

wherein, the public PUCCH resource set table comprises at least one group of parameter information for public PUCCH transmission, and each group of parameter information corresponds to one index information respectively; the first index information is used for determining one set of parameter information corresponding to the first index information in at least one set of parameter information as the first parameter information.

Optionally, the UE may determine at least part of parameter information in a set of parameter information corresponding to the first index information in the at least one set of parameter information as the first parameter information according to the first index information.

Optionally, in an embodiment of the present application, each set of parameter information in the common PUCCH resource set table includes at least one of the following:

number of common PUCCH repeated transmissions;

a common PUCCH format;

a common PUCCH cyclic shift index set;

a start symbol of the common PUCCH repeated transmission;

the number of symbols of the common PUCCH repeated transmission;

physical resource module (PRB) offset of common PUCCH repeated transmission;

the common PUCCH repeats the transmitted termination symbols.

It should be noted that, the explanation of the parameter information in the common PUCCH resource set table may be referred to above, and will not be repeated here.

Optionally, the common PUCCH resource set table is configured by a protocol, preconfigured, or network side device.

The common PUCCH resource set table includes a PUCCH resource set before common PUCCH resource allocation.

Table 1 is a common PUCCH resource set table provided in the embodiments of the present application.

TABLE 1

As shown in table 1, the common PUCCH resource set table includes 16 rows of parameter information, and the 16 rows of parameter information correspond to indexes 0 to 15, respectively. The PUCCH format (PUCCH format) corresponding to index (index) 0 is PUCCH format0, the start symbol (First symbol) is 10, the number of symbols (Number of symbols) is 2, the PRB offset (PRB offset) is 3, and the initial CS index set (Set of initial CS indexes) and the repetition number (Repetition Number) are 2.

The PRB offset may be also referred to asThe number of repetitions, i.e., the number of retransmissions, or the number of retransmissions.

Illustratively, the set of parameter information is at least one row of parameter information in the common PUCCH resource set table.

Illustratively, the second index information includes at least one index field, each index field including at least one bit, and at least one bit in one index field is used to indicate the first index information. For example, if one bit of the second index information indicates that the field is 0000, the indicated first index information may be 0; for another example, if one bit of the second index information indicating a field is 0001, the indicated first index information may be 1.

In an example, the UE may search, according to first index information indicated by the network side device, parameter information corresponding to the first index information in the common PUCCH resource set table, and determine the parameter information as parameter related information of common PUCCH repeated transmission.

For example, when the network side device sends the PDSCH carrying the Msg2 with the second indication information, and the first indication information indicated by the second indication information is 2 and the index in the common PUCCH resource set table is 2, the corresponding PUCCH format is PUCCH format0, the starting symbol is 10, the number of symbols is 2, the prb offset is 3, and the number of repeated transmissions is 2, and the UE may determine, according to the parameter information corresponding to the index 2 in the common PUCCH resource set table, that the PUCCH format of the common PUCCH repeated transmission is PUCCH format0, the starting symbol is 10, the number of symbols is 2, the prb offset is 3, and the number of repeated transmissions is 2, and is transmission in the slot.

Note that, if First symbol+num_symbols Repetition Number >14, it means inter-slot repetition, i.e., inter-slot transmission, and if First symbol+num_symbols Repetition Number is less than or equal to 14, it means intra-slot repetition, i.e., intra-slot transmission.

It should be noted that the UE may determine partial parameter information for common PUCCH repeated transmission from only the common PUCCH resource set table according to the index information, for example, determine the number of repeated transmissions from only the common PUCCH resource set table.

In this way, the UE may determine, according to the second indication information sent by the network side device, parameter related information of the UE for performing common PUCCH retransmission through the common PUCCH resource set table, so as to avoid additional signaling overhead.

Optionally, in an embodiment of the present application, the common PUCCH resource set table includes M first PUCCH resource set tables; or the public PUCCH resource set table is a PUCCH resource set table obtained by expanding an initial PUCCH resource set table, wherein the initial PUCCH resource set table is preconfigured, agreed by a protocol or configured by a network side;

the common PUCCH repeated transmission numbers of each first PUCCH resource set table in the M first PUCCH resource set tables are different, and each group of common PUCCH repeated transmission numbers in each first PUCCH resource set table are the same, where M is a positive integer.

In some embodiments of the present application, the M first PUCCH resource set tables include three PUCCH resource set tables. The three PUCCH resource set tables may be as shown in table 1, table 2, and table 3.

Table 2 is another common PUCCH resource set table provided in an embodiment of the present application.

TABLE 2

As shown in table 2, the common PUCCH resource set table includes 16 rows of parameter information, and the 16 rows of parameter information correspond to indexes 0 to 15, respectively. For the description of each row of parameters, reference may be made to the description of the parameter information when the index is 0 in table 1, which is not repeated here.

For example, the network side device carries second indication information in the PDSCH carrying Msg4, where the first index information indicated by the second indication information is 1, and the UE may determine, according to the parameter information corresponding to the index 1 in the common PUCCH resource set table, that the PUCCH format of the common PUCCH repeated transmission is PUCCH format0, the starting symbol is 4, the number of symbols is 2, the prb offset is 0, and the number of repeated transmissions is 4, and is repeated in the slot.

Table 3 is another common PUCCH resource set table provided in an embodiment of the present application.

TABLE 3 Table 3

As shown in table 3, the common PUCCH resource set table includes 16 rows of parameter information, and the 16 rows of parameter information correspond to indexes 0 to 15, respectively. For the description of each row of parameters, reference may be made to the description of the parameter information when the index is 0 in table 1, which is not repeated here.

For example, in the case where the number of rows of the parameter information in the PUCCH resource set table is less than or equal to 16, the network side device may indicate the above first index information by 4 bits, that is, PUCCH-resource common is 4 bits.

For example, the network side device carries, in DCI for transmitting the PDSCH for scheduling the ms 2, second indication information, where the first index information indicated by the second indication information is 7, and the UE may determine, according to parameter information corresponding to the index of 7 in the common PUCCH resource set table, that PUCCH format of the common PUCCH repeated transmission is PUCCH format1, the starting symbol is 4, the number of symbols is 10, the prb offset is 0, and the number of repeated transmissions is 8, and is repeated between slots.

Note that the numbers of common PUCCH repeated transmissions in table 1, table 3 and table 3 are different, and the numbers of common PUCCH repeated transmissions in each row of parameter information in table 1, table 2 and table 3 are the same, for example, the numbers of common PUCCH repeated transmissions in each row of parameter information in table 1 are all 2.

In some embodiments of the present application, the PUCCH resource set table obtained by expanding the initial PUCCH resource set table includes a PUCCH resource set table. The PUCCH resource set table obtained by the expansion may be as shown in table 4 below.

Table 4 is another common PUCCH resource set table provided in an embodiment of the present application.

TABLE 4 Table 4

As shown in table 4, the common PUCCH resource set table includes 16 rows of parameter information, and the 16 rows of parameter information correspond to indexes 0 to 43, respectively. For the description of each row of parameters, reference may be made to the description of the parameter information when the index is 0 in table 1, which is not repeated here.

It should be noted that, in the common PUCCH resource set table obtained by this extension, only the parameter information of partial repeated transmission is listed, and other parameter information that is not listed but can be deduced therefrom is also within the protection scope of the present application.

It should be noted that, the foregoing rows of parameter information listed in each table (table 1 to table 4) are only examples of some possible cases provided in the embodiments of the present application, and not limiting the parameter information in the present application, more rows of parameter information may be set according to actual requirements, for example, the case that PUCCH format is PUCCH format1, first symbol is 10,Number of symbols is 4, and repeated transmission between time slots is performed may be added to the table, and the parameter information that is not listed in the table but can be deduced therefrom is also within the protection scope of the present application.

For example, for the extended common PUCCH resource set table, since the table includes more than 16 rows of parameter information, in this case, the network side device may indicate the above-mentioned first index information by 6 bits, that is, extend PUCCH-resource common from 4 bits to 6 bits.

For example, the network side device carries, in DCI for transmitting PDSCH of scheduled bearer MsgB, second indication information, where the first index information indicated by the second indication information is 10, and the UE may determine, according to parameter information corresponding to the index of 10 in the common PUCCH resource set table, that PUCCH format of common PUCCH repeated transmission is PUCCH format1, the starting symbol is 4, the number of symbols is 10, the prb offset is 4, and the number of repeated transmissions is 1.

Optionally, in the embodiment of the present application, in a case where the common PUCCH resource set table includes multiple PUCCH resource set tables, the network side device may send indication information to the UE, where the indication information is used to indicate a target common PUCCH resource set table in the multiple PUCCH resource set tables, and the UE may determine the common PUCCH resource set table to be searched according to the indication information.

The indication information may be the second indication information described above or indication information different from the second indication information, for example. For example, the indication information is indication information carried by the network side device in the PDSCH carrying the Msg 2.

For example, the network side device carries, in DCI for transmitting PDSCH of the scheduled bearer MsgB, second indication information, where the first index information indicated by the second indication information is 7, and the indicated target common PUCCH resource set table is a common PUCCH resource set table corresponding to the above-mentioned symbol 2, and the UE may index, in the common PUCCH resource set table corresponding to the above-mentioned symbol 2, corresponding parameter information when the index is 7.

In this way, the UE may determine the parameter related information of the UE for performing the common PUCCH repeated transmission through one common PUCCH resource set table of the multiple newly added common PUCCH resource set tables or the common PUCCH resource set table obtained after expansion, thereby avoiding additional signaling overhead.

Optionally, in the embodiment of the present application, in a case where the second indication information is used to indicate the number of common PUCCH repeated transmissions and the second index information, the parameter related information of the common PUCCH repeated transmissions includes the number of common PUCCH repeated transmissions and the second parameter information determined from the second PUCCH resource set table;

wherein, the second PUCCH resource set table includes at least one set of parameter information for common PUCCH transmission, where each set of parameter information corresponds to one index information; the second index information is used for determining one group of parameter information corresponding to the second index information in the at least one group of parameter information as the second parameter information.

Optionally, in an embodiment of the present application, each set of parameter information in the second PUCCH resource set table includes at least one of the following:

a common PUCCH format;

a common PUCCH cyclic shift index set;

a start symbol of the common PUCCH repeated transmission;

the number of symbols of the common PUCCH repeated transmission;

PRB offset of common PUCCH repeated transmission;

the common PUCCH repeats the transmitted termination symbols.

Alternatively, the second PUCCH resource set table may be the initial PUCCH resource set table.

Table 5 is a second PUCCH resource set table provided in an embodiment of the present application.

TABLE 5

As shown in table 5, the common PUCCH resource set table includes 16 rows of parameter information, and the 16 rows of parameter information correspond to indexes 0 to 15, respectively. For the description of each row of parameters, reference may be made to the description of the parameter information when the index is 0 in table 1, which is not repeated here.

For example, the network side device carries second indication information in the PDSCH carrying MsgB, where the second indication information indicates that the second index information is 0 and indicates that the number of common PUCCH repeated transmissions is 8, and according to the second indication information, the UE may search, from table 5, for parameter information of PUCCH repeated transmissions corresponding to the index information being 0, that is, PUCCH format is 0, starting symbol is 12, and symbol number is 2, and then perform common PUCCH repeated transmissions based on the parameter information and the indicated number of repeated transmissions.

In this way, the UE may determine the parameter related information for common PUCCH repeated transmission according to the index information indicated by the network side device and the number of repeated transmissions, thereby avoiding additional signaling overhead.

Optionally, in the embodiment of the present application, the second indication information is specifically configured to indicate parameter related information of common PUCCH repeated transmission corresponding to one or more specific common PUCCH formats.

For example, the second indication information is sent through target signaling, where the target signaling is used to indicate a repeated transmission parameter of a common PUCCH of a first common PUCCH format corresponding to the target signaling, and different common PUCCH formats are configured with corresponding signaling independently.

Optionally, the specific public PUCCH format is agreed by a protocol, predefined or configured by a network side device.

For example, PUCCH Format0 and the corresponding repeated transmission parameter of PUCCH Format0 are configured by #rep-Format 0; and configuring the PUCCH Format1 and the corresponding repeated transmission parameters of the PUCCH Format1 through #rep-Format 1.

In this way, by configuring the corresponding PUCCH format and the corresponding repeated transmission parameter using independent parameters, the reliability of parameter configuration is improved.

Optionally, in the embodiment of the present application, in a case where the first information includes at least a first offset, an effective time of the common PUCCH retransmission includes any one of the following:

After the last symbol of the PDSCH corresponding to the common PUCCH, passing through a time domain position corresponding to the symbol corresponding to the first offset;

after the time slot of the PDSCH corresponding to the public PUCCH passes through the time domain position corresponding to the first symbol of the time slot corresponding to the first offset, the time domain position is effective time;

after the last symbol of the scheduling DCI of the PDSCH corresponding to the public PUCCH passes through the time domain position corresponding to the symbol of one of the first offset;

and generating an effective time at a time domain position corresponding to a symbol of a time slot corresponding to a first offset after the time slot of the PDSCH corresponding to the public PUCCH where the scheduling DCI is located.

The first offset may be 1 or more slots, or 1 or more symbols, which is not limited in the embodiment of the present application.

It should be noted that, in the embodiment of the present application, the granularity of measuring the time domain position may be a time slot (slot) (may be 1 slot,2 slots, or more slots), a symbol (symbol) (may be 1 symbol,2 symbols, or more symbols), a millisecond (ms) (may be 1ms,2ms, or more ms), or a second(s) (may be 1s,2s, or more s), or may be granularity of his feasibility, which may be specifically determined according to practical use requirements, and embodiments of the present application are not limited.

For example, in the case where the first information is carried by the PDSCH carrying the Msg2 and/or the Msg4, the effective time may be a time-domain position corresponding to a next symbol of a last symbol of the PDSCH carrying the Msg2 and/or the Msg 4. That is, the UE may start common PUCCH repeated transmission at the next symbol of the last symbol of the PDSCH carrying Msg2 and/or Msg4 according to the instruction of the network side device.

For example, in the case where the first information is carried by the PDSCH carrying the MsgB, the effective time may be a time-domain position corresponding to two symbols after the last symbol of the PDSCH carrying the MsgB.

For example, the last symbol of PDSCH carrying MsgB is symbol 1, and symbol 1 is followed by symbol 2, symbol 3, symbol 4, etc., and then the effective time is two symbols after symbol 1, that is, the time domain position corresponding to symbol 4. That is, the UE may start common PUCCH repetition transmission at the symbol 4 according to an instruction of the network side device.

For example, in the case that the first information is carried by DCI of PDSCH of the scheduling bearer Msg2 and/or Msg4, the effective time may be a time-domain position corresponding to a symbol next to a last symbol of the scheduling DCI. That is, the UE may start common PUCCH repeated transmission at the next symbol of the last symbol of DCI scheduling PDSCH carrying Msg2 and/or Msg4 according to an instruction of the network side device.

For example, in the case where the first information is carried by the PDSCH carrying the Msg2 and/or the Msg4, the effective time may be a time domain position corresponding to the first symbol of the next slot after the slot where the PDSCH carrying the Msg2 and/or the PDSCH carrying the Msg4 is located. That is, the UE may start common PUCCH retransmission at the first symbol of the next slot of the slots carrying the PDSCH of Msg2 and/or Msg4 according to the instruction of the network side device.

For example, in the case where the first information is carried by DCI of PDSCH of Msg2 and/or Msg4, the effective time may be a time domain position corresponding to a first symbol of a next time slot of the PDSCH of Msg 4. That is, the UE may start to perform the common PUCCH retransmission at the first symbol of the next slot of the slots where the DCI carrying the PDSCH of Msg2 and/or Msg4 is scheduled according to the indication of the network side device.

For example, in the case where the first information is carried by DCI of PDSCH of Msg2 and/or Msg4, the effective time may be a time-domain position corresponding to a first symbol of a time slot corresponding to a time slot after a time slot in which DCI of PDSCH of Msg4 is located and passing through a time slot (i.e., one time slot after the time slot in which the DCI is located).

For example, the time slot in which the DCI of the PDSCH carrying the Msg2 is scheduled is time slot 1, and the time slots after the time slot 1 are time slots 2 and 3, respectively, and the time slot corresponding to the time slot after the time slot 1 passing through one time slot is time slot 3, where the effective time is the time domain position corresponding to the first symbol of the time slot 3.

In this way, the UE may determine the effective time of the repeated transmission of the common PUCCH according to the first offset indicated by the network side device, so that the repeated transmission of the PUCCH may be performed on the common PUCCH, thereby improving the reliability and efficiency of the PUCCH transmission
