In the fifth generation mobile communication technologies 5G NR and NR NTN, in order to enhance coverage of a wireless signal, a repeated transmission technology of a channel is often used to repeatedly transmit the same data on the channel to improve reliability of data transmission.

For the repeated transmission technique of the PUCCH using the common PUCCH resource, the base station needs to transmit signaling to the UE to configure the number of repeated transmissions of the PUCCH, and the PUCCH using the common PUCCH resource includes the Msg4 HARQ ACK PUCCH and another PUCCH (hereinafter referred to as a first PUCCH) using the common PUCCH resource different from the Msg4 HARQ ACK PUCCH.

In the prior art, for the Msg4 HARQ ACK PUCCH, a base station can broadcast a system information block SIB to configure the repeated transmission times for the Msg4 HARQ ACK PUCCH, and the repeated transmission times are basically not changed after being configured; the base station can also indicate the repeated transmission times of the Msg4 HARQ ACK PUCCH to the UE by sending DCI with a format of DCI1_0 of TC-RNTI scrambling CRC, but the repeated transmission times are the same as the repeated transmission times configured by the base station through SIB, namely, the repeated transmission times of the Msg4 HARQ ACK PUCCH configured for the UE cannot be changed.

For the first PUCCH, the number of repeated transmissions configured by the base station is the same as the number of repeated transmissions of the Msg4 HARQ ACK PUCCH, which also does not change.

From the above analysis, it can be seen that, in the prior art, whether the Msg4 HARQ ACK PUCCH or the first PUCCH, after configuring the number of repeated transmissions for the UE, the number of repeated transmissions according to which the UE transmits the PUCCH using the common PUCCH resource or the base station receives the PUCCH using the common PUCCH resource does not substantially change any more; even if the current link condition changes, the number of retransmissions is not changed, and therefore, the number of retransmissions may not be suitable for the current link, and the existing configuration method for the number of retransmissions has a certain limitation.

Based on this, the embodiment of the application provides a communication method, in which the number of repeated transmission times of the PUCCH using the common PUCCH resource can be redetermined according to whether the report of the repeated transmission capability of the UE is received, so that the number of transmission times more suitable for the current link condition can be configured for the UE in the following, thereby breaking the limitation of the existing configuration method.

The communication method provided by the embodiment of the application can be applied to the communication system architecture schematic diagram shown in fig. 1. As shown in fig. 1, the communication system includes: base station and multiple UEs, assume that multiple UEs include UE1, UE2, UE3 and UE4 in the figure. It should be noted that the communication system shown in fig. 1 may be applicable to different networks, for example, a global system for mobile communications (Global System of Mobile communication, abbreviated as GSM), code Division multiple access (Code Division Multiple Access, abbreviated as CDMA), wideband code Division multiple access (Wideband Code Division Multiple Access, abbreviated as WCDMA), time Division-synchronization code Division multiple access (Time Division-Synchronous Code Division Multiple Access, abbreviated as TD-SCDMA), long term evolution (Long Term Evolution, abbreviated as LTE) system, and future 5G networks. Alternatively, the communication system may be a system in a scenario of high reliability low latency communication (URLLC) transmission in a 5G communication system.

Thus, alternatively, the base station may be a base station (Base Transceiver Station, abbreviated BTS) and/or a base station controller in GSM or CDMA, a base station (NodeB, abbreviated NB) and/or a radio network controller (Radio Network Controller, abbreviated RNC) in WCDMA, an evolved base station (Evolutional Node B, abbreviated eNB or eNodeB) in LTE, or a relay station or an access point, or a base station (gNB) in a future 5G network, which may be deployed on the ground or on a satellite, or the like, and the invention is not limited herein.

In particular, the communication system shown in fig. 1 is applicable to NR NTN, where a satellite device with a wider network coverage provides a wireless communication service for a UE, where the base station in fig. 1 may include a satellite device.

The UE may be a wireless terminal or a wired terminal. A wireless terminal may be a device that provides voice and/or other traffic data connectivity to a user, a handheld device with wireless connectivity, or other processing device connected to a wireless modem. The wireless terminal may communicate with one or more core network devices via a radio access network (Radio Access Network, RAN for short), which may be mobile terminals such as mobile phones (or "cellular" phones) and computers with mobile terminals, for example, portable, pocket, hand-held, computer-built-in or vehicle-mounted mobile devices that exchange voice and/or data with the radio access network. For another example, the wireless terminal may be a personal communication service (Personal Communication Service, abbreviated PCS) phone, a cordless phone, a session initiation protocol (Session Initiation Protocol, abbreviated SIP) phone, a wireless local loop (Wireless Local Loop, abbreviated WLL) station, a personal digital assistant (Personal Digital Assistant, abbreviated PDA) or the like. A wireless Terminal may also be referred to as a system, subscriber Unit (Subscriber Unit), subscriber Station (Subscriber Station), mobile Station (Mobile Station), mobile Station (Mobile), remote Station (Remote Station), remote Terminal (Remote Terminal), access Terminal (Access Terminal), user Terminal (User Terminal), user Agent (User Agent), user equipment (User Device or User Equipment), without limitation. Optionally, the UE may also be a device such as a smart watch, a tablet computer, or the like.

It should be noted that, the above communication system and the network architecture shown in fig. 1 are for more clearly describing the technical solution of the embodiment of the present application, and do not constitute a limitation on the technical solution provided by the embodiment of the present application. As one of ordinary skill in the art can appreciate, with the evolution of the communication system and the network architecture, the technical solution provided by the embodiments of the present application is also applicable to similar technical problems.

Fig. 2 is a schematic implementation flow chart of a communication method according to an embodiment of the present application, where the method is applied to the base station in fig. 1, as shown in fig. 2, and the method includes the following steps 201 to 203:

in step 201, the base station sends the UE the configuration information of the number of repeated transmissions of the target PUCCH.

The target PUCCH is a PUCCH using a common PUCCH resource, and the target PUCCH includes an Msg4HARQ ACK PUCCH, or the target PUCCH includes an Msg4HARQ ACK PUCCH and a first PUCCH different from the Msg4HARQ ACK PUCCH among the PUCCHs using the common PUCCH resource.

It can be understood that the base station may send the transmission number configuration information of the Msg4HARQ ACK PUCCH to all UEs within the coverage area of the base station by broadcasting SIB, and the base station may also send the transmission number configuration information of the first PUCCH to all UEs within the coverage area of the base station by broadcasting SIB; the base station broadcasts the transmission time configuration information of the Msg4HARQ ACK PUCCH and the transmission time configuration information of the first PUCCH at different occasions.

Or, the base station may send the configuration information of the number of repeated transmissions of the Msg4HARQ ACK PUCCH and the configuration information of the number of repeated transmissions of the first PUCCH to the specific UE at different occasions in a unicast manner.

In step 202, the base station detects the retransmission capability report of the UE.

In some embodiments, the base station may detect, after sending the retransmission number configuration information of the Msg4HARQ ACK PUCCH to the UE, retransmission capability reporting of the UE; in other embodiments, the base station may also detect the retransmission capability report of the UE after sending the retransmission number configuration information of the Msg4HARQ ACK PUCCH to the UE and sending the retransmission number configuration information of the first PUCCH to the UE; the embodiment of the present application is not limited thereto.

The base station sends the retransmission times configuration information of the Msg4HARQ ACK PUCCH before the base station sends the retransmission times configuration information of the first PUCCH.

In step 203, the base station determines the target number of repeated transmissions of the target PUCCH according to whether the repeated transmission capability report of the UE is received.

It can be understood that after the number of repeated transmissions of the target PUCCH is configured for the UE, the number of repeated transmissions is not always unchanged, but can be determined again according to whether the repeated transmission capability report of the UE is received, so that the number of repeated transmissions matched with the current link state can be reconfigured for the UE, thereby breaking the limitation of the existing method.

Further, the base station detects that the result of reporting the transmission capability of the UE is different, and the determined target repeated transmission times of the target PUCCH are different.

Fig. 3 is a schematic flow chart of an implementation of the communication method provided in the present embodiment, as shown in fig. 3, the method includes the following steps 301 to 304; steps 302 to 304 are further explained with respect to step 203 in the corresponding embodiment of fig. 2.

In step 301, the base station sends the UE the configuration information of the number of repeated transmissions of the target PUCCH.

The retransmission configuration information of the target PUCCH includes a retransmission number configuration manner and a retransmission number configuration list, and in this embodiment, the retransmission number configuration manner may be a Single retransmission Factor (Single Factor) or Multiple retransmission factors (Multiple factors).

If the repeated transmission times configuration mode indicated by the repeated transmission times configuration information is a single transmission factor; the retransmission times configuration list includes one retransmission times.

If the repeated transmission times configuration mode indicated by the repeated transmission times configuration information is a plurality of transmission factors; the retransmission number configuration list includes a plurality of retransmission numbers.

Step 302, a base station detects the report of the repeated transmission capability of the UE; if the retransmission capability report of the UE is not received, step 303 is executed, and if the retransmission capability report of the UE is received, step 304 is executed.

In step 303, the base station determines the target retransmission times as a preset value.

The embodiment of the application does not limit the preset value, and the preset value is larger than 0; in a preferred embodiment, the preset value is 1.

It can be understood that if the base station does not receive the report of the retransmission capability of the UE, it indicates that, for the target PUCCH, the UE does not need to repeat transmission more than 1 time, and therefore, the target number of repeat transmissions may be 1.

In step 304, the base station acquires an uplink measurement result, and determines a target retransmission number according to the uplink measurement result.

It can be understood that if the base station receives the report of the retransmission capability of the UE, it indicates that for the target PUCCH, the UE needs more than 1 retransmission; at this time, in order to further determine the number of repeated transmissions of the target PUCCH, the base station may acquire an uplink measurement result, and determine the target number of repeated transmissions based on the uplink measurement result.

In this embodiment, the target retransmission times may be determined preliminarily according to whether the retransmission capability report of the UE is received, and further, in the case that the retransmission capability report of the UE is not received, the target retransmission times may be determined further according to the uplink measurement result, so that the determined target retransmission times are more suitable for the current link.

In the above embodiment, whether the configuration mode of the number of repeated transmissions is a single repeated transmission factor or multiple repeated transmission factors, if the repeated transmission capability report of the UE is not received, the base station determines that the target number of repeated transmissions is a preset value, and the base station does not send a signaling indicating the target number of repeated transmissions to the UE, so as to save signaling overhead. The base station may agree with the UE that both the Msg4 HARQ ACK PUCCH and the first PUCCH are transmitted with a number of retransmissions of 1.

In other embodiments, whether the retransmission number configuration mode is a single retransmission factor or multiple retransmission factors, the base station determines that the target retransmission number is a preset value without receiving the retransmission capability report of the UE, and then the base station needs to send signaling to the UE to indicate that the target retransmission number is a preset value, and for different types of PUCCHs, the base station indicates to the UE that the target retransmission number is a different mode.

Based on this, the embodiment of the present application provides a communication method, and an implementation flow chart of the method is shown in fig. 4, where the method of this embodiment is intended to illustrate how a base station sends signaling to UE to indicate that the target number of repeated transmissions is a preset value; as shown in fig. 4, the method of the present embodiment includes steps 305 to 308 after step 303 of the embodiment of fig. 3:

In step 305, the base station sends a first signaling to the UE, where the format of the first signaling is DCI format 1_0 of TC-RNTI scrambling CRC, and a first field of the first signaling of the format carries indication information of a target number of repeated transmissions of the Msg4 HARQ ACK PUCCH, where the indication information indicates that the target number of repeated transmissions of the Msg4 HARQ ACK PUCCH is a preset value.

Wherein the first field is all or part of the specified field/existing field in DCI 1_0 of TC-RNTI scrambling CRC, or the first field is a newly added field.

In one possible implementation, the first field may be the least significant bit (Least Significant Bit, LSB) of the downlink allocation index (Downlink Assignment Index) field or the most significant bit (Most Significant Bit, MSB) of the downlink allocation index field.

Here, the length of the first field is 1bit, the value of the first field is a value in the first index table, and the first index table includes 1 value, which may be 0 or 1, and the value is used to indicate that the target number of repeated transmissions of the Msg4 HARQ ACK PUCCH is a preset value.

Table 1 below is one example of a first index table corresponding to values in a first field of DCI 1_0 of a TC-RNTI scrambling CRC:

TABLE 1

First field	Indication information
		0	The target number of repeated transmissions is a preset value

In step 306, the base station receives, for the Msg4 HARQ ACK PUCCH, the target number of repeated transmissions indicated based on the preset value.

As described above, the preset value is 1, and the base station receives the Msg4 HARQ ACK PUCCH transmitted by the UE according to the target number of repeated transmissions "1".

In step 307, the base station sends the first signaling to the UE again, where the format of the first signaling is DCI format 1_0 of the C-RNTI-scrambled CRC or DCI format 1_1 of the C-RNTI-scrambled CRC, and the indication information of the target number of repeated transmissions of the first PUCCH carried in the first field of the first signaling of the format indicates that the target number of repeated transmissions of the first PUCCH is a preset value.

In this step, the first field may be a part or all of a specified field/existing field of the DCI format 1_0i of the C-RNTI-scrambled CRC or the DCI format 1_1 of the C-RNTI-scrambled CRC, or the first field is a newly added field.

In one possible embodiment, the first field may be the LSB of the downlink allocation index or the MSB of the downlink allocation index field.

Here, the length of the first field is 1bit, the value of the first field is a value in the first index table, and the first index table includes 1 value, which may be 0 or 1, for indicating that the target number of repeated transmissions of the first PUCCH is a preset value. The first index table corresponding to the DCI format 1_0I of the C-RNTI scrambled CRC or the DCI format 1_1 of the C-RNTI scrambled CRC is also shown in Table 1.

In step 308, the base station receives, for the first PUCCH, the target number of repeated transmissions based on the preset value indication.

As described above, the preset value is 1, and the base station receives the first PUCCH transmitted by the UE according to the target number of repeated transmissions "1".

In this embodiment, it is described that, in the case where no terminal capability report of the UE is received, DCI of different formats is transmitted for different PUCCH types to indicate the target number of repeated transmissions of the PUCCH of different types as a preset value.

It should be noted that, in the above steps 305 to 308, the implementation step of indicating the target number of repeated transmissions to the Msg4HARQ ACK PUCCH and the first PUCCH is described in the case where the target PUCCH includes the Msg4HARQ ACK PUCCH and the first PUCCH, in this case, the base station sends two first signaling to the UE, the formats of the two first signaling are different, and if the target PUCCH includes only the Msg4HARQ ACK PUCCH, only steps 305 to 306 are required to be executed.

The transmission frequency configuration mode indicated by the transmission frequency configuration information sent by the base station comprises single repeated transmission factor and multiple repeated transmission factor configuration, and for the case that the base station receives the report of the repeated transmission capacity of the UE, the base station acquires an uplink measurement result, determines the repeated transmission frequency of the Msg4HARQ ACK PUCCH and the first PUCCH based on the uplink measurement result, and then sends signaling to the Msg4HARQ ACK PUCCH and the first PUCCH respectively to indicate the target repeated transmission frequency. However, for different transmission number configuration modes, the indication mode of the target repeat transmission number is also different.

Fig. 5 provides a communication method, which is intended to illustrate an indication manner of a target retransmission number when a base station receives a report of retransmission capability of a UE and a transmission number configuration manner is a single retransmission factor, and the method in this embodiment includes steps 3041 to 3045a and 3041 to 3045b after the method 302 in the embodiment of fig. 3, where the target retransmission number indicated by the single transmission factor is not equal to a preset value.

In step 3041, the base station determines signal parameters of Msg1 and/or Msg3 in the random access procedure, and determines a target number of repeated transmissions of the Msg4 HARQ ACK PUCCH based on the signal parameters of Msg1 and Msg 3.

In some embodiments, the base station may obtain the signal parameters of Msg1 and/or Msg3 by measurement during random access.

The signal parameters include signal strength and/or signal to interference and noise ratio (Signal to Interference plus Noise Ratio, SINR), that is, the base station determines at least one of: signal strength of Msg1, signal strength of Msg3, SINR of Msg1, SINR of Msg 3.

It may be understood that the target PUCCH includes an Msg4 HARQ ACK PUCCH and a first PUCCH, and after the base station receives the report of the repeated transmission capability of the UE, determines the target number of repeated transmissions of the Msg4 HARQ ACK PUCCH and the target number of repeated transmissions of the first PUCCH, and since the Msg4 HARQ ACK PUCCH is transmitted in the random access process and the first PUCCH is transmitted after the random access is completed, the timing for determining the number of repeated transmissions of the Msg4 HARQ ACK PUCCH is before the timing for determining the number of repeated transmissions of the first PUCCH.

In some embodiments, the target number of repeated transmissions of the Msg4 HARQ ACK PUCCH is inversely related to the signal strength of Msg1 and/or Msg3, or inversely related to the SINR of Msg1 and/or Msg 3.

After determining the target number of repeated transmissions of the Msg4 HARQ ACK PUCCH, DCI signaling needs to be sent to the UE to indicate the target number of repeated transmissions of the Msg4 HARQ ACK PUCCH.

In this embodiment, when the base station transmits DCI to the UE to indicate the number of repeated transmissions of the target PUCCH, the information indicated by the first field in the DCI may be different, but the result of the number of repeated transmissions configured for the UE is the same, for example, the base station may indicate the number of repeated transmissions of the target PUCCH to the UE by the first indication manner described in steps 3042a to 3045a, or the base station may indicate the number of repeated transmissions of the target PUCCH to the UE by the second indication manner described in steps 3042b to 3045 b.

As described above, the first indication manner includes the following steps 3042a to 3045a:

in step 3042a, the base station sends a first signaling to the UE, where the format of the first signaling is DCI 1_0 of the TC-RNTI scrambling CRC, and a first field of the first signaling of the format carries information indicating a target number of repeated transmissions of the Msg4 HARQ ACK PUCCH, where the information indicates one of: the single repeat transmission factor is disabled, the single repeat transmission factor is enabled, and the target repeat transmission number of the Msg4 HARQ ACK PUCCH is the repeat transmission number indicated by any function value of the single repeat transmission factor.

In this step, the first field is all or part of the specified/existing field in DCI 1_0 of the TC-RNTI scrambling CRC, or the first field is a newly added field.

Here, the first field has a length log ₂ The value of the first field is a value in a second index table, which may include N values.

When n=2, the length of the first field is 1bit, and the first field may be, for example, LSB 1bit of the downlink allocation index or MSB 1bit of the downlink allocation index field.

Accordingly, the first field in the second index table includes 2 values for indicating the single retransmission factor indicated by the disabled and enabled retransmission times configuration information, respectively. When n=2, the second index table is shown in table 2 below:

TABLE 2

Value of the first field	Indication information
		0	Disabling a single retransmission factor (Disable)
1	Enabling a single retransmission factor (Enable)

In this embodiment, when a single retransmission factor is disabled, the target number of repeated transmissions of the Msg4 HARQ ACK PUCCH is a preset value, and the UE transmits the Msg4 HARQ ACK PUCCH according to the target number of repeated transmissions corresponding to the preset value; when the single repeat transmission factor is started, the target repeat transmission times of the Msg4 HARQ ACK PUCCH are the repeat transmission times indicated by the single repeat transmission factor, and the UE transmits the Msg4 HARQ ACK PUCCH according to the target repeat transmission times indicated by the single repeat transmission factor.

When N is greater than 2, the second index table includes values of N first fields, 2 values of the N values are respectively used to indicate disabling and enabling of the single retransmission factor, N-2 values different from the 2 values of the N values are respectively used to indicate that the target number of repeated transmissions of the Msg4 HARQ ACK PUCCH is a value of a first function of the single retransmission factor indicated by the number of repeated transmissions configuration information, the target number of repeated transmissions is a value … of a second function of the single retransmission factor indicated by the number of repeated transmissions configuration information, and the target number of repeated transmissions is a value of an N-2 function of the single retransmission factor indicated by the number of repeated transmissions configuration information.

The first function, the second function …, and the N-2 function are different from each other.

In some embodiments, the value of the first function may be a product of a first preset coefficient and a number of repeated transmissions of the Msg4 HARQ ACK PUCCH indicated by the single repeated transmission factor, the value of the second function may be a product … of the number of repeated transmissions of the Msg4 HARQ ACK PUCCH indicated by the single repeated transmission factor of the second preset coefficient, and the value of the N-2 function may be a product of the N-2 preset coefficient and the number of repeated transmissions of the Msg4 HARQ ACK PUCCH indicated by the single repeated transmission factor.

The embodiment of the application does not limit the first preset coefficient to the N-2 preset coefficient, and the first preset coefficient to the N-2 preset coefficient are different from each other. The first to N-2 th preset coefficients may be any number greater than 0 and less than 1, or may be any number greater than 1.

Illustratively, when the first field length is 2 bits and n=4, the first field may be 2 bits of the downlink allocation index field, and the second index table is as shown in table 3 below:

TABLE 3 Table 3

Value of the first field	Indication information
		00	Disabling a single retransmission factor (Disable)
01	Enabling a single retransmission factor (Enable)
		10	The target number of retransmissions is the value of a first function of the single retransmission factor
11	The target number of retransmissions is the value of the second function of the single retransmission factor

For example, as shown in table 3, assuming that the number of repeated transmissions indicated by a single repeated transmission factor is 5 and the first preset coefficient is 2, the value of the first function is 2×4=8; the second preset coefficient is 0.5, and the target number of repeated transmissions indicated by the single repeated transmission factor is 4, and then the value of the second function is 4×0.5=2.

It may be appreciated that after the base station transmits the first signaling to the UE to indicate the target number of repeated transmissions of the Msg4 HARQ ACK PUCCH, the UE transmits the Msg4 HARQ ACK PUCCH to the base station based on the target number of repeated transmissions.

In step 3043a, the base station receives the Msg4 HARQ ACK PUCCH based on the target number of repeated transmissions of the Msg4 HARQ ACK PUCCH.

In step 3044a, the base station determines the signal strength and/or SINR of the historical uplink signal, and determines the target number of repeated transmissions of the first PUCCH based on the signal strength and/or SINR of the historical uplink signal.

In a preferred embodiment, the historical uplink signal is an uplink signal near the current time.

Step 3045a, sending a first signaling to the UE, where the format of the first signaling is DCI format 1_0 of the C-RNTI-scrambled CRC or DCI format 1_1 of the C-RNTI-scrambled CRC, and a first field of the first signaling of the format carries indication information of a target number of repeated transmissions of the first PUCCH, where the indication information indicates one of: disabling single repetition transmission factor, enabling single repetition transmission factor, target repetition transmission number of first PUCCH is any function value of single repetition transmission factor.

In this step, the first field is either all or part of a specified field/existing field in the DCI format 1_0 of the C-RNTI-scrambled CRC or the DCI format 1_1 of the C-RNTI-scrambled CRC, or the first field is a newly added field.

When n=2, the first field is 1bit in length, and the first field in the second index table includes 2 values, and illustratively, the first field may be LSB 1bit or MSB 1bit of the modulation and coding scheme field. The 2 values are used to indicate disabling and enabling, respectively, the single retransmission factor indicated by the retransmission times configuration information. When n=2, the second index table is shown in table 2 above.

In this embodiment, when a single retransmission factor is disabled, the target retransmission number of the first PUCCH is a preset value, and the UE transmits the first PUCCH according to the target retransmission number corresponding to the preset value; when the single repeat transmission factor is started, the target repeat transmission times of the first PUCCH are the repeat transmission times indicated by the single repeat transmission factor, and the UE transmits the first PUCCH according to the target repeat transmission times indicated by the single repeat transmission factor.

When N is greater than 2, the second index table includes values of N first fields, 2 values of the N values are respectively used to indicate disabling and enabling of the single retransmission factor, N-2 values different from the 2 values of the N values are respectively used to indicate that the target number of repeated transmissions of the first PUCCH is a value of a first function of the single retransmission factor indicated by the repeated transmission number configuration information, the target number of repeated transmissions of the first PUCCH is a value … of a second function of the single retransmission factor indicated by the repeated transmission number configuration information, and the target number of repeated transmissions of the first PUCCH is a value of an N-2 function of the single retransmission factor indicated by the repeated transmission number configuration information.

In some embodiments, the first function may be a product of a first preset coefficient and a number of repeated transmissions of the first PUCCH indicated by the single repeated transmission factor, the second function may be a product … of a second preset coefficient and a number of repeated transmissions of the first PUCCH indicated by the single repeated transmission factor, and the N-2 function may be a product of an N-2 preset coefficient and a number of repeated transmissions of the first PUCCH indicated by the single repeated transmission factor.

Illustratively, when the first field length is 2 bits and n=4, the first field length may be LSB 2 bits or MSB 2 bits of the modulation and coding scheme, and the second index table is as shown in table 3 above.

For example, as shown in table 3 above, the first preset coefficient is 2, the target number of repeated transmissions of the first PUCCH indicated by the single repeated transmission factor is 4, and then the value of the first function is 2×4=8; the second preset coefficient is 0.5, the target number of repeated transmissions of the first PUCCH indicated by the single repeated transmission factor is 4, and the value of the second function is 4×0.5=2.

In step 3046a, the base station receives the first PUCCH based on the target number of repeated transmissions of the first PUCCH.

In the above steps 3042a to 3045a, it is described how to indicate the UE the number of repeated transmissions of the target PUCCH when the target PUCCH includes the Msg4HARQ ACK PUCCH and the first PUCCH, and if the target PUCCH includes only the Msg4HARQ ACK PUCCH, only the steps 3042a to 3043a are required to be performed.

As described above, the second indication manner includes the following steps 3042b to 3045b:

in step 3042b, the base station sends a first signaling to the UE, where the format of the first signaling is DCI format 1_0 of TC-RNTI scrambling CRC, and a first field of the first signaling of the format carries indication information of a target number of repeated transmissions of Msg4HARQ ACK PUCCH, where the indication information indicates one of: the target number of repeated transmissions of the Msg4HARQ ACK PUCCH is a preset value, the target number of repeated transmissions of the Msg4HARQ ACK PUCCH is the number of repeated transmissions indicated by a single repeated transmission factor, and the target number of repeated transmissions of the Msg4HARQ ACK PUCCH is the number of repeated transmissions indicated by any function value of the single repeated transmission factor.

When n=2, the length of the first field is 1bit, and the first field in the second index table includes 2 values, and illustratively, the first field may be LSB 1bit of the downlink allocation index or MSB 1bit of the downlink allocation index field. The 2 values are respectively used for indicating that the target number of repeated transmissions of the Msg4HARQ ACK PUCCH is a preset value and the target number of repeated transmissions of the Msg4HARQ ACK PUCCH is the number of repeated transmissions indicated by a single repeated transmission factor. When n=2, the second index table is shown in table 4 below:

TABLE 4 Table 4

Value of the first field	Indication information
		0	The target number of repeated transmissions is a preset value
1	The target number of repeated transmissions is a single repeated transmission factor

When N is greater than 2, the second index table includes values of N first fields, 2 values of N values are used to indicate that the target number of repeated transmissions of the Msg4HARQ ACK PUCCH is a preset value and the target number of repeated transmissions of the Msg4HARQ ACK PUCCH is a number of repeated transmissions indicated by a single repeated transmission factor, N-2 values different from the 2 values of N values are used to indicate that the target number of repeated transmissions of the Msg4HARQ ACK PUCCH is a value of a first function of a single repeated transmission factor indicated by the repeated transmission number of repeated transmission configuration information of the Msg4HARQ ACK PUCCH, the target number of repeated transmissions of the Msg4HARQ ACK PUCCH is a value … of a second function of a single repeated transmission factor indicated by the repeated transmission number of repeated transmission configuration information of the Msg4HARQ ACK PUCCH, and the target number of repeated transmissions of the Msg4HARQ ACK is a value of an N-2 function of a single repeated transmission factor indicated by the repeated transmission number of configuration information of the Msg4HARQ ACK PUCCH.

In some embodiments, the first function may be a product of a first preset coefficient and a number of repeated transmissions of the Msg4HARQ ACK PUCCH indicated by the single repeated transmission factor, the second function may be a product … of a second preset coefficient and a number of repeated transmissions of the Msg4HARQ ACK PUCCH indicated by the single repeated transmission factor, and the N-2 function may be a product of an N-2 preset coefficient and a number of repeated transmissions of the Msg4HARQ ACK PUCCH indicated by the single repeated transmission factor.

Illustratively, when the first field length is 2 bits and n=4, the first field may be 2 bits of the downlink allocation index field, and the second index table is as shown in table 5 below:

TABLE 5

First field	Indication information
		00	The target number of repeated transmissions is a preset value
01	The target number of repeated transmissions is a single repeated transmission factor
		10	The target number of retransmissions is the value of a first function of the single retransmission factor
11	Target weightThe number of complex transmissions being the value of a second function of a single repeat transmission factor

Illustratively, as shown in table 3, assuming that the target number of repeated transmissions indicated by the single repeated transmission factor is 4 and the first preset coefficient is 2, the value of the first function is 2×4=8; the second preset coefficient is 0.5, and the value of the second function is 4×0.5=2.

In step 3043b, the base station receives the Msg4 HARQ ACK PUCCH based on the target number of repeated transmissions of the Msg4 HARQ ACK PUCCH.

In step 3044b, the base station determines the signal strength and/or SINR of the historical uplink signal, and determines the target number of repeated transmissions of the first PUCCH based on the signal strength and/or SINR of the historical uplink signal.

In step 3045b, the base station sends a first signaling to the UE, where the format of the first signaling is DCI format 1_0 of the C-RNTI-scrambled CRC or DCI format 1_1 of the C-RNTI-scrambled CRC, and a first field of the first signaling of the format carries indication information of a target number of repeated transmissions of the first PUCCH, where the indication information indicates one of: the target number of repeated transmissions of the first PUCCH is a preset value, the target number of repeated transmissions of the first PUCCH is a number of repeated transmissions indicated by a single repeated transmission factor, and the target number of repeated transmissions of the first PUCCH is a number of repeated transmissions indicated by any function value of the single repeated transmission factor.

When n=2, the first field is 1bit in length, and the first field in the second index table includes 2 values, and illustratively, the first field may be LSB 1bit or MSB 1bit of the modulation and coding scheme field. The 2 values are respectively used for indicating that the target number of repeated transmissions of the first PUCCH is a preset value and the target number of repeated transmissions of the first PUCCH is a number of repeated transmissions indicated by a single repeated transmission factor. When n=2, the second index table is shown in table 4 above. When N is greater than 2, the second index table includes values of N first fields, 2 values of the N values are respectively used to indicate that the target number of repeated transmissions of the first PUCCH is a preset value and the target number of repeated transmissions of the first PUCCH is a number of repeated transmissions indicated by a single repeated transmission factor, N-2 values of the N values different from the 2 values are respectively used to indicate that the target number of repeated transmissions of the first PUCCH is a value of a first function of the single repeated transmission factor indicated by the repeated transmission number configuration information of the first PUCCH, the target number of repeated transmissions of the first PUCCH is a value … of a second function of the single repeated transmission factor indicated by the repeated transmission number configuration information of the first PUCCH, and the target number of repeated transmissions of the first PUCCH is a value of an N-2 function of the single repeated transmission factor indicated by the repeated transmission number configuration information of the first PUCCH.

In some embodiments, the first function may be a product of a first preset coefficient and a number of repeated transmissions of the first PUCCH indicated by the single repeated transmission factor, the second function may be a product … of the number of repeated transmissions of the first PUCCH indicated by the single repeated transmission factor of the second preset coefficient, and the N-2 function may be a product of the N-2 preset coefficient and the number of repeated transmissions of the first PUCCH indicated by the single repeated transmission factor.

Illustratively, when the first field length is 2 bits and n=4, the first field length may be LSB 2 bits or MSB 2 bits of the modulation and coding scheme, and the second index table is shown in table 5 above.

For example, as shown in table 3, if the first preset coefficient is 2 and the target number of repeated transmissions of the first PUCCH indicated by the single repeated transmission factor is 4, the value of the first function is 2×4=8; the second preset coefficient is 0.5, the target number of repeated transmissions of the first PUCCH indicated by the single repeated transmission factor is 4, and the value of the second function is 4×0.5=2.

The first indication mode is different from the second indication mode in that: in the first indication manner, the value of the first field in the second index table may indicate disabling and enabling of the single retransmission factor, which characterizes the target number of repeated transmissions of the target PUCCH as a preset value or the number of repeated transmissions indicated by the single retransmission factor; in the second indication manner, the value of the first field in the second index table does not indicate that the single retransmission factor is disabled or enabled, and directly indicates that the target retransmission number is a preset value or the retransmission number indicated by the single retransmission factor.

In practical application, any one of the first indication mode and the second indication mode may be selected according to an application requirement to indicate the target repeat transmission times of the target PUCCH to the UE, which is not limited by the present application.

In step 3046b, the base station receives the first PUCCH based on the target number of repeated transmissions of the first PUCCH.

In the above steps 3042b to 3046b, it is described how to indicate the UE the number of repeated transmissions of the target PUCCH when the target PUCCH includes the Msg4 HARQ ACK PUCCH and the first PUCCH, and if the target PUCCH includes only the Msg4 HARQ ACK PUCCH, only the steps 3042a to 3043a are required to be performed.

Fig. 6 provides how the base station indicates the target number of repeated transmissions of the target PUCCH to the UE when the base station receives the report of the repeated transmission capability of the UE and the transmission number configuration of the target PUCCH is a plurality of repeated transmission factors. The method comprises steps 601 to 608:

in step 601, the base station sends the UE the configuration information of the number of repeated transmissions of the target PUCCH.

The repeated transmission frequency configuration mode indicated in the repeated transmission frequency configuration information is a plurality of repeated transmission factors, and the characterization repeated transmission frequency configuration list comprises a plurality of transmission frequencies.

In step 602, the base station receives a report of the transmission capability of the UE.

In step 603, the base station determines signal parameters of Msg1 and/or Msg3 in the random access procedure, and determines a target number of repeated transmissions of the Msg4 HARQ ACK PUCCH based on the signal parameters of Msg1 and Msg 3.

In step 604, the base station sends a first signaling to the UE, where the format of the first signaling is DCI format 1_0 of TC-RNTI scrambling CRC, and a first field of the first signaling of the format carries indication information of a target number of repeated transmissions of the Msg4 HARQ ACK PUCCH, where the indication information indicates that the target number of repeated transmissions of the Msg4 HARQ ACK PUCCH is any one of the repeated transmission numbers in the repeated transmission number configuration list.

Any one retransmission number in the retransmission number configuration list may also be described as any value in the retransmission number configuration list.

In this step, the first field may be all or part of the specified/existing field in DCI 1_0 of the TC-RNTI scrambling CRC, or the first field may be a newly added field.

The length of the first field is related to the number of the multiple repeated transmission times, the value of the first field is a value in a third index table, and the third index table comprises multiple values which are respectively used for indicating the multiple repeated transmission times in the transmission time configuration list.

In some embodiments, M is the number of multiple transmission times in the configuration list of the number of repeated transmission times, and the first field has a length of P bit, then p=log2 ^M 。

Illustratively, the number of the multiple transmission times in the retransmission times configuration list is 2, the length of the first field is 1bit, illustratively, the first field may be LSB 1bit of the downlink allocation index field or MSB 1bit of the downlink allocation index field, and the third index table is as shown in the following table 6:

TABLE 6

Value of the first field	Indication information
		0	The target number of retransmission is 1 st value in the retransmission number configuration list
1	The target retransmission times is the 2 nd value in the retransmission times configuration list

Illustratively, the number of the plurality of transmission times in the retransmission times configuration list is 4, the length of the first field is 2 bits, and the third index table is shown in the following table 7:

TABLE 7

Value of the first field	Indication information
		00	The target number of retransmission is 1 st value in the retransmission number configuration list
01	The target retransmission times is the 2 nd value in the retransmission times configuration list
		10	The target retransmission times is the 3 rd value in the retransmission times configuration list
11	The target retransmission times is the 4 th value in the retransmission times configuration list

In some embodiments, as shown in table 6 and table 7 above, in the third index table, the values of the first field are arranged in ascending order from small to large, where the nth value corresponds to the nth retransmission number in the retransmission number configuration list.

In step 605, the base station receives the Msg4 HARQ ACK PUCCH based on the target number of transmissions of the Msg4 HARQ ACK PUCCH.

In step 606, the base station determines the signal strength and/or SINR of the historical uplink signal, and determines the target number of repeated transmissions of the first PUCCH based on the signal strength and/or SINR of the historical uplink signal.

In step 607, the base station sends a first signaling to the UE, where the format of the first signaling is DCI format 1_0 of the C-RNTI-scrambled CRC or DCI format 1_1 of the C-RNTI-scrambled CRC, and a first field of the first signaling of the format carries indication information of a target number of repeated transmissions of the first PUCCH, where the indication information indicates that the target number of repeated transmissions of the first PUCCH is any one of the repeated transmission times in the repeated transmission times configuration list.

The length of the first field is related to the number of multiple repeated transmission times in the repeated transmission times configuration list, the value of the first field is a value in a third index table, and the third index table comprises multiple values which are respectively used for indicating the multiple repeated transmission times in the repeated transmission times configuration list.

In this step, the first field may be all or part of a specified field/existing field in DCI format 1_0 of the C-RNTI-scrambled CRC or DCI format 1_1 of the C-RNTI-scrambled CRC, or the first field may be a newly added field.

In some embodiments, M is the number of multiple transmission times in the configuration list of the repeated transmission times, and the length of the first field is P bit, then p=log2 ^M 。

Illustratively, the number of retransmission times in the retransmission times configuration list is 2, the length of the first field is 1bit, illustratively, the first field is LSB 1bit of the modulation and coding scheme, and the third index table is as in table 6 above.

Illustratively, the number of the plurality of repeated transmissions is 4, the length of the first field is 2 bits, and the third index table is as in table 7 above.

After the UE receives the first signaling, the UE sends a first PUCCH to the base station based on the target repeated transmission times indicated by the first signaling.

In step 608, the base station receives, for the first PUCCH, based on the target number of repeated transmissions of the first PUCCH.

The embodiment of the application further provides a communication method, which describes the interaction relationship between the UE and the base station when the base station indicates the repeated transmission times of the target PUCCH to the UE based on the uplink condition under the condition that the base station receives the report of the repeated capability of the UE. Fig. 7 is a schematic implementation flow chart of a communication method according to an embodiment of the present application, as shown in fig. 7, the method includes the following steps 701 to 713:

In step 701, the base station sends repeated transmission number configuration information of a target PUCCH to the UE.

The target PUCCH includes an Msg4 HARQ ACK PUCCH, or an Msg4 HARQ ACK PUCCH and a first PUCCH.

The base station can respectively send the configuration information of the repeated transmission times of the Msg4 HARQ ACK PUCCH and the first PUCCH to the UE in a broadcast mode, and can also respectively send the configuration information of the repeated transmission times of the Msg4 HARQ ACK PUCCH and the first PUCCH to the UE in a unicast mode.

In step 702, the ue reports the retransmission capability.

In step 703, the base station detects that the UE has repeated transmission capability reporting.

In step 704, the base station determines a target number of repeated transmissions of the Msg4 HARQ ACK PUCCH.

The target number of repeated transmissions of the Msg4 HARQ ACK PUCCH may be described with reference to the corresponding embodiment of fig. 3, which is not described herein.

In step 705, the base station transmits a first signaling to the UE, where the format of the first signaling is DCI format 1_0 of the TC-RNTI scrambling CRC.

The first field of the first signaling of the format carries indication information of the target number of repeated transmissions of the Msg4 HARQ ACK PUCCH.
