[0060] To facilitate understanding of the technical solutions of the embodiments of the present application, the technical solutions of the present application are described in detail below through specific embodiments. The following related technologies can be combined with the technical solutions of the embodiments of the present application as optional solutions, and they all fall within the scope of protection of the embodiments of the present application. The embodiments of the present application include at least part of the following contents.

[0061] To facilitate a better understanding of the embodiments of the present application, the PRACH in the random access process related to the present application is described.

[0062] NR defines 256 configurations of Random Access Channel (RACH) resources for accessing UEs. The RACH resource configuration information used by the cell is indicated to the accessing UE in the system message. Each RACH resource configuration includes: preamble format, period, radio frame offset, subframe number within the radio frame, starting symbol within the subframe, number of PRACH slots within the subframe, number of PRACH opportunities within the PRACH slot, and PRACH opportunity duration. This information is used to determine the time, frequency, and code information of the PRACH resource.

[0063] Based on the RACH resource configuration indicated by the system message, the association between the Synchronization Signal Block (SSB) and the PRACH resource is also indicated. This allows the UE to determine the available PRACH resources, including the PRACH timing and preamble, based on the detected SSB and this association. The UE measures the SSB and determines the SSB that meets the Reference Signal Received Power (RSRP) threshold, and uses the PRACH resource associated with the SSB to send the preamble.

[0064] It should be noted that SSB can also be called synchronization signal / physical broadcast channel block (SS / PBCH block).

[0065] During the random access process, the main purpose of the UE sending the Preamble is to inform the network that there is a random access request. After sending the preamble, the UE will monitor the Physical Downlink Control Channel (PDCCH) within the RAR time window to receive the RAR corresponding to the Random Access Radio Network Temporary Identity (RA-RNTI). The UE will detect the RAR after each preamble transmission. If the network does not receive the RAR in response within this RAR time window, the UE will send the preamble again on the next available PRACH resource, and the transmission power of the preamble will increase by one step. The network will configure the maximum number of preamble transmissions. When the number of preamble transmissions reaches the maximum number and the UE still does not receive the RAR, the random access process fails.

[0066] To facilitate a better understanding of the embodiments of the present application, the repetition of PRACH related to the present application is described.

[0067] During random access, after the UE sends a PRACH, it receives the RAR sent by the network in the RAR reception window. If the UE does not receive the RAR, it will retransmit the PRACH on the next available PRACH resource and increase the PRACH power by one step.

[0068] However, in coverage-limited situations, the UE cannot increase the PRACH power infinitely to allow the network to detect it. To improve PRACH coverage performance, repeated PRACH transmissions were introduced in NR evolution. As shown in Figure 2, repeated PRACH transmissions (transmitting four random access messages 1 (message 1, Msg 1)) correspond to the same RAR reception window (random access message 2 (message 2, Msg 2)). The network can combine and receive repeated PRACH transmissions to improve detection performance, thereby improving PRACH coverage.

[0069] To facilitate a better understanding of the embodiments of the present application, the power control of the PRACH related to the present application is described.

[0070] PRACH power control uses an open-loop power control mechanism. The UE sets the PRACH transmit power based on factors such as the expected receive power configured by the network and the path loss measured by the downlink reference signal. During the random access process, if the UE sends PRACH but does not receive the network's RAR or does not successfully receive the conflict resolution message, the UE needs to retransmit the PRACH. When the NR UE supports multiple transmit beams, when the transmit beam remains unchanged, the retransmitted PRACH transmit power increases based on the previously transmitted PRACH power until the random access process is successfully completed.

[0071] In some embodiments, the power control of PRACH is determined by the following formula 1.

[0072] P PRACH,b,f,c (i) = min{P CMAX,f,c (i),P PRACH,target,f,c +PL b,f,c}[dBm] Formula 1

[0073] Among them, P PRACH,target,f,c Indicates the target received power (PREAMBLE_RECEIVED_TARGET_POWER) of the PRACH determined by the Media Access Control (MAC) layer; PL b,f,c P represents the path loss measured by the UE on carrier f for the activated uplink BWP b based on the downlink reference signal (RS) associated with the PRACH transmission in the activated downlink bandwidth part (BWP) of the serving cell c; PRACH,target,f,c and PL b,f,c The calculated power is the power determined by the open-loop power control; P CMAX,f,c(i) is the maximum output power of the UE at transmission opportunity i in serving cell c on carrier f. Specifically, PREAMBLE_RECEIVED_TARGET_POWER = preambleReceivedTargetPower + DELTA_PREAMBLE + (PREAMBLE_POWER_RAMPING_COUNTER – 1) × PREAMBLE_POWER_RAMPING_STEP + POWER_OFFSET_2STEP_RA; where preambleReceivedTargetPower is the target received power of the PRACH configured by higher layers.

[0074] In some embodiments, the power of the PUSCH (ie, Msg 3 PUSCH) sent in message 3 (Msg 3) during the random access process is calculated using the following formula 2.

[0075] P PUSCH (i) = min{P CMAX ,P0+10log 10 (M(i))+α·PL+Δ TF (i)+f(i)} Formula 2

[0076] Among them, P CMAX is the maximum transmit power of the UE; Po = P O_PRE +Δ PREAMBLE_Msg3 , P O_PRE is the target receiving power of the Preamble, Δ PREAMBLE_Msg3 is the power offset parameter of Msg 3; M(i) is the number of resource blocks (RBs) used by PUSCH; PL is the path loss measured by the downlink RS associated with PRACH transmission; α is the path loss compensation factor; Δ TF (i) is the power offset value of different modulation and coding scheme (MCS) formats relative to the reference MCS format; f(i) is the adjustment amount of PUSCH transmit power, and its initial value is f(0) = ΔP rampup +δ msg2 , ΔP rampup is the total increase in random access preamble transmission power, δ msg2 It is the value of the Transmission Power Control (TPC) command carried in the RAR.

[0077] Specifically, the initial PRACH transmit power is determined by the target receive power configured by higher layers, the measured path loss, and the number and step size of PRACH power ramps. For the UE, open-loop power control can be used to determine the initial PRACH power. Then, through gradual power ramps, the network can successfully detect the preamble sent by the UE. This avoids transmitting with power exceeding the required level, reducing interference caused by the UE.

[0078] The Msg3 PUSCH transmit power setting is related to the PRACH power. Specifically, the Msg3 PUSCH transmit power is determined based on the PRACH power ramp results, the power offset parameter, and the TPC command indicated in the RAR. Therefore, during multiple PRACH transmissions, its power continuously ramps up to enable the network to successfully detect the preamble sent by the UE. The preamble transmit power detected by the network serves as a reference for the Msg3 PUSCH transmission power, enabling more reasonable Msg3 PUSCH power settings and improving transmission coverage.

[0079] In order to facilitate a better understanding of the embodiments of the present application, the problems solved by the present application are explained.

[0080] Repeated PRACH transmission is intended to improve PRACH coverage. However, the power of Msg 3 PUSCH is set based on the result of a single PRACH transmission, without considering repeated PRACH transmission. It is possible that the power of Msg 3 PUSCH cannot achieve a coverage level similar to that of repeated PRACH transmission, resulting in a decrease in Msg 3 PUSCH coverage performance.

[0081] Based on the above problems, this application proposes a solution for determining the transmit power of Msg3 PUSCH. In the PRACH repeated transmission scenario, the transmit power of PUSCH during random access can be determined more reasonably, thereby improving the transmission performance of PUSCH during random access.

[0082] The technical solution of this application is described in detail below through specific embodiments.

[0083] FIG3 is a schematic flowchart of a wireless communication method 200 according to an embodiment of the present application. As shown in FIG3 , the wireless communication method 200 may include at least part of the following contents:

[0084] S210, the terminal device determines the transmission power of PUSCH in the random access process based on the first information: wherein the first information is at least one of the following: the number of PRACH repeated transmissions, the PRACH transmission power in the PRACH repeated transmissions, the number of times the PRACH repeated transmission process is executed, the information indicated in the RAR, and the power bias parameter related to the PRACH repeated transmission.

[0085] In an embodiment of the present application, the terminal device can determine the transmission power of the PUSCH in the random access process based on the number of PRACH repeated transmissions, the PRACH transmission power in the PRACH repeated transmissions, the number of times the PRACH repeated transmission process is executed, the information indicated in the RAR, and at least one of the power bias parameters related to the PRACH repeated transmission. The transmission power of the PUSCH in the random access process can be determined more reasonably, thereby improving the transmission performance of the PUSCH in the random access process.

[0086] In some embodiments, the PUSCH in the random access process is the PUSCH sent in message 3 (Msg3) in the four-step random access process, or the PUSCH in the random access process is the PUSCH sent in message B (MsgB) in the two-step random access process.

[0087] The following description is made by taking the PUSCH in the random access process as the PUSCH sent in message 3 (Msg 3 PUSCH) in the four-step random access process as an example.

[0088] The embodiment of the present application is applied to the PRACH repeated transmission scenario. The terminal device performs multiple PRACH transmissions during a PRACH repeated transmission process. When the network receives, it can merge the multiple PRACH transmissions to achieve reception performance that cannot be achieved by a single PRACH transmission, thereby improving the coverage of the PRACH transmission. In other words, the multiple PRACH transmissions in a PRACH repeated transmission process correspond to one RAR receiving window. That is, the multiple PRACH transmissions corresponding to one RAR can be called a PRACH repeated transmission process, and a PRACH repeated transmission process includes multiple PRACH transmissions. For example, as shown in Figure 4, the first PRACH repeated transmission process includes 4 PRACH transmissions, the second PRACH repeated transmission process also includes 4 PRACH transmissions, and the third PRACH repeated transmission process includes 6 PRACH transmissions.

[0089] It should be noted that for a PRACH repeated transmission process, since the power of multiple PRACH transmissions can be accumulated and received on the network side, the power of a PRACH transmission in a PRACH repeated transmission process does not need to meet the reception on the network side, especially in scenarios with limited network coverage. Even if the transmission power of a single PRACH transmission is set to the maximum transmission power of the terminal device, it still cannot be successfully received by the network. In other words, after adopting PRACH repeated transmission, it is unreasonable for the transmission power of subsequent Msg3 PUSCH to be based on the power of a certain PRACH transmission in the PRACH repeated transmission process responded by the network. The successful reception of PRACH is not based on the power of a certain PRACH transmission in the PRACH repeated transmission process, but is the result of the overall combined reception of multiple PRACH transmissions in the PRACH repeated transmission process. The transmit power of Msg3 PUSCH is based on the power of a PRACH transmission during repeated PRACH transmissions acknowledged by the network. It is possible that the power of Msg3 PUSCH cannot achieve a coverage level similar to that of repeated PRACH transmissions, resulting in a decrease in Msg3 PUSCH coverage performance. Based on the embodiments of the present application, in the PRACH repeated transmission scenario, the transmit power of Msg3 PUSCH can be more reasonably determined, thereby improving the transmission performance of Msg3 PUSCH.

[0090] The technical solution of this application is described in detail below through specific embodiments.

[0091] In embodiment 1, the first information is the number of PRACH repetition transmissions, that is, the terminal device determines the transmission power of the PUSCH in the random access process according to the number of PRACH repetition transmissions.

[0092] It should be noted that PRACH retransmissions can achieve better coverage than a single PRACH transmission. Therefore, the number of PRACH transmissions included in a PRACH retransmission process can reflect the PRACH coverage level. If the PRACH retransmission is not successfully received by the network, it means that the current PRACH retransmission process does not meet the coverage requirements for the current terminal device to reach the base station. One method is to increase the number of PRACH transmissions in the next PRACH retransmission process to achieve better coverage. As shown in Figure 4, the first PRACH retransmission process includes four PRACH transmissions (network unacknowledged), the second PRACH retransmission process also includes four PRACH transmissions (network unacknowledged), and the third PRACH retransmission process includes six PRACH transmissions. If a PRACH retransmission process is successfully received by the network, it means that the current PRACH retransmission process meets the coverage requirements for the current terminal device to reach the base station. To achieve similar coverage as PRACH, the transmit power of the PUSCH (such as the Msg3 PUSCH) during the random access process can refer to the number of PRACH transmissions in the PRACH retransmission process that was acknowledged by the network. As shown in FIG4 , assuming that the third PRACH retransmission process is acknowledged by the network, the transmit power of the PUSCH (eg, Msg3 PUSCH) in the random access process may refer to the PRACH transmission number 6 of the third PRACH retransmission process.

[0093] Optionally, in embodiment 1, the terminal device determines the transmit power of the PUSCH in the random access process according to the number of PRACH repetition transmissions included in the target PRACH repetition transmission process;

[0094] The target PRACH retransmission process is a PRACH retransmission process responded by the network through the RAR in at least one PRACH retransmission process.

[0095] For example, as shown in FIG4 , it is assumed that the third PRACH repetition transmission process is responded by the network, that is, the target PRACH repetition transmission process is the third PRACH repetition transmission process among the three PRACH repetition transmission processes.

[0096] Optionally, in Example 1, the terminal device determines the adjustment amount of the PUSCH transmission power based on the number of PRACH repetition transmissions included in the target PRACH repetition transmission process; and the terminal device determines the PUSCH transmission power in the random access process based on the adjustment amount of the PUSCH transmission power.

[0097] In some optional implementations of embodiment 1, the terminal device determines the adjustment amount of the PUSCH transmit power according to the number of PRACH repetition transmissions included in the target PRACH repetition transmission process, including:

[0098] The terminal device determines the power adjustment amount related to the number of PRACH repetition transmissions according to the number of PRACH repetition transmissions included in the target PRACH repetition transmission process; and the terminal device determines the adjustment amount of the PUSCH transmission power according to the power adjustment amount related to the number of PRACH repetition transmissions.

[0099] In some optional implementations, the correspondence between the number of PRACH repetition transmissions and the power adjustment amount is agreed upon by a protocol, or the correspondence between the number of PRACH repetition transmissions and the power adjustment amount is configured by a network device.

[0100] In some optional implementations, the correspondence between the number of PRACH repetition transmissions and the power adjustment amount may also be determined based on a preset rule, which may be a function, a table, or the like.

[0101] Specifically, the parameter f(i) in the above formula 2 is set to ΔP rep +δ msg2 , where ΔP rep is the power adjustment amount related to the number of PRACH transmissions included in the PRACH retransmission process responded by the network (i.e., the target PRACH retransmission process). For example, when the number of PRACH transmissions included in the PRACH retransmission process responded by the network (i.e., the target PRACH retransmission process) is 4, ΔP rep =ΔP1; when the number of PRACH transmissions included in the PRACH retransmission process responded by the network (ie, the target PRACH retransmission process) is 6, ΔP rep =ΔP2.

[0102] In some optional implementations of embodiment 1, the terminal device determines the adjustment amount of the PUSCH transmit power according to the number of PRACH repetition transmissions included in the target PRACH repetition transmission process, including:

[0103] The terminal device determines the power adjustment amount related to the increase in the number of PRACH repetition transmissions based on the increase in the number of PRACH repetition transmissions included in the target PRACH repetition transmission process compared to the number of PRACH repetition transmissions included in the first PRACH repetition transmission process; and the terminal device determines the adjustment amount of the PUSCH transmission power based on the power adjustment amount related to the increase in the number of PRACH repetition transmissions.

[0104] In some optional implementations, the correspondence between the increase in the number of PRACH repetition transmissions and the power adjustment amount is agreed upon by a protocol, or the correspondence between the increase in the number of PRACH repetition transmissions and the power adjustment amount is configured by a network device.

[0105] In some optional implementations, the correspondence between the increase in the number of PRACH repetition transmissions and the power adjustment amount may also be determined based on a preset rule, which may be a function, a table, or the like.

[0106] Specifically, the parameter f(i) in the above formula 2 is set to ΔP rep +δ msg2 , where ΔP rep is the power adjustment amount related to the increase in the number of PRACH transmissions included in the PRACH retransmission process responded by the network (i.e., the target PRACH retransmission process) compared to the number of PRACH transmissions included in the first PRACH retransmission process. For example, as shown in FIG4 , the number of PRACH transmissions included in the PRACH retransmission process responded by the network is 6, and the increase in the number of PRACH transmissions included in the first PRACH retransmission process is 2, and ΔP rep is the power adjustment amount associated with the increase of 2 in the number of PRACH transmissions.

[0107] In embodiment 2, the first information is the PRACH transmission power in PRACH repeated transmission, that is, the terminal device determines the PUSCH transmission power in the random access process according to the PRACH transmission power in the PRACH repeated transmission.

[0108] It should be noted that if the terminal device does not receive the RAR from the network after performing a PRACH retransmission process, it will perform the PRACH retransmission process again. In addition to increasing the number of PRACH transmissions during the next PRACH retransmission process, the PRACH transmit power during the PRACH transmission may also be increased to improve PRACH coverage. When calculating the power of the Msg3 PUSCH, you can refer to the PRACH transmit power during the PRACH retransmission process responded by the network, or refer to the total PRACH power increase during multiple PRACH retransmission processes.

[0109] In some optional implementations, the PRACH transmit power of different PRACH retransmissions in a PRACH retransmission process is the same. For example, the PRACH transmit power in a PRACH retransmission process remains unchanged, and the PRACH transmit power in a subsequent PRACH retransmission process is increased by one step compared to the PRACH transmit power in the previous PRACH retransmission process.

[0110] In some optional implementations of Example 2, the terminal device determines the transmit power of the PUSCH in the random access process based on the PRACH transmit power in the target PRACH retransmission process; wherein the target PRACH retransmission process is a PRACH retransmission process in which the network responds via an RAR during at least one PRACH retransmission process. The PRACH transmit power of different PRACH retransmissions in a PRACH retransmission process is the same.

[0111] In some optional implementations of Example 2, the terminal device determines the transmit power of the PUSCH in the random access process based on the increase in the PRACH transmit power in the target PRACH retransmission process compared to the PRACH transmit power in the first PRACH retransmission process; wherein the target PRACH retransmission process is a PRACH retransmission process in which the network responds through an RAR during at least one PRACH retransmission process. The PRACH transmit power of different PRACH retransmissions in one PRACH retransmission process is the same.

[0112] Specifically, in Example 2, it is assumed that the transmit power of PRACH remains unchanged during one PRACH repeated transmission, and the transmit power of PRACH during the subsequent PRACH repeated transmission is increased by one step compared to the transmit power of PRACH during the previous PRACH repeated transmission. The transmit power of Msg3 PUSCH refers to the transmit power of PRACH during the PRACH repeated transmission responded by the network, or refers to the total increase in PRACH transmit power during multiple PRACH repeated transmissions. The total increase in PRACH transmit power can be the increase in the power of one PRACH transmission during the PRACH repeated transmission responded by the network compared to the power of one PRACH transmission during the first PRACH repeated transmission of the terminal device.

[0113] In some optional implementations, different PRACH transmissions in a PRACH repetition transmission process may have different PRACH transmit powers. That is, in a PRACH repetition transmission process, different PRACH transmissions may have different transmit powers, for example, power ramping may be performed.

[0114] In some optional implementations of Example 2, the terminal device determines the transmit power of the PUSCH in the random access process based on the PRACH transmit power of the first target PRACH transmission in the target PRACH repeated transmission process; wherein the target PRACH repeated transmission process is a PRACH repeated transmission process in which the network responds through the RAR during at least one PRACH repeated transmission process. The PRACH transmit power of different PRACH transmissions in a PRACH repeated transmission process is different.

[0115] In some implementations, the first target PRACH transmission is the first or last PRACH transmission in the target PRACH repeated transmission process. Of course, the first target PRACH transmission may also be other PRACH transmissions in the target PRACH repeated transmission process, which is not limited in this embodiment.

[0116] In some optional implementations of Example 2, the terminal device determines the transmit power of the PUSCH in the random access process based on the increase in the PRACH transmit power of the second target PRACH transmission in the target PRACH repeated transmission process compared to the PRACH transmit power of the third target PRACH transmission in the first PRACH repeated transmission process; wherein the target PRACH repeated transmission process is a PRACH repeated transmission process in which the network responds through RAR during at least one PRACH repeated transmission process. The PRACH transmit power of different PRACH transmissions in one PRACH repeated transmission process is different.

[0117] In some implementations, the second target PRACH transmission is the first or last PRACH transmission during the target PRACH repeated transmission process, and the third target PRACH transmission is the first or last PRACH transmission during the first PRACH repeated transmission process. Of course, the second target PRACH transmission may also be another PRACH transmission during the target PRACH repeated transmission process, and this embodiment is not limited to this. The third target PRACH transmission may also be another PRACH transmission during the first PRACH repeated transmission process, and this embodiment is not limited to this.

[0118] For example, the second target PRACH transmission is the first PRACH transmission in the target PRACH repeated transmission process, and the third target PRACH transmission is the first PRACH transmission in the first PRACH repeated transmission process.

[0119] For another example, the second target PRACH transmission is the last PRACH transmission in the target PRACH repeated transmission process, and the third target PRACH transmission is the last PRACH transmission in the first PRACH repeated transmission process.

[0120] For another example, the second target PRACH transmission is the first PRACH transmission in a target PRACH repeated transmission process, and the third target PRACH transmission is the last PRACH transmission in the first PRACH repeated transmission process.

[0121] For another example, the second target PRACH transmission is the last PRACH transmission in the target PRACH repeated transmission process, and the third target PRACH transmission is the first PRACH transmission in the first PRACH repeated transmission process.

[0122] Specifically, in Example 2, during a PRACH retransmission, the transmission power of different PRACH transmissions may be different, for example, may be increased. At this time, the transmission power of Msg3 PUSCH refers to the power of a certain PRACH during the PRACH retransmission process responded by the network, such as the first or last time. Alternatively, the transmission power of Msg3 PUSCH refers to the total increase in PRACH power during multiple PRACH retransmissions. Specifically, the total increase in PRACH power may be the increase in the power of a certain PRACH transmission during the PRACH retransmission process responded by the network compared to the power of a certain PRACH transmission during the first PRACH retransmission of the terminal device, for example, the increase in the power of the first or last PRACH transmission during the PRACH retransmission process responded by the network compared to the power of the first or last PRACH transmission during the first PRACH retransmission of the terminal device.

[0123] In Example 3, the first information is the number of PRACH repeated transmissions and the PRACH transmission power in the PRACH repeated transmissions, that is, the terminal device determines the transmission power of the PUSCH in the random access process based on the number of PRACH repeated transmissions and the PRACH transmission power in the PRACH repeated transmissions.

[0124] It should be noted that if a terminal device does not receive a RAR from the network after performing a PRACH retransmission, it can perform another PRACH retransmission. This can be achieved by increasing the number of PRACH transmissions or by increasing the PRACH transmit power to improve coverage. It is possible to use both methods simultaneously, increasing the number of PRACH transmissions while also increasing the PRACH transmit power. In other words, PRACH coverage is achieved by both increasing the number of PRACH retransmissions and increasing the PRACH transmit power.

[0125] In some optional implementations of Example 3, the terminal device determines the transmission power of the PUSCH in the random access process based on the number of PRACH repetition transmissions included in the target PRACH repetition transmission process and the PRACH transmission power of the PRACH repetition transmission in the target PRACH repetition transmission process; wherein the target PRACH repetition transmission process is a PRACH repetition transmission process in which the network responds through RAR in at least one PRACH repetition transmission process.

[0126] In some optional implementations, the terminal device determines the transmit power of the PUSCH in the random access process based on the number of PRACH repetition transmissions included in the target PRACH repetition transmission process and the PRACH transmit power of the PRACH repetition transmission in the target PRACH repetition transmission process, including:

[0127] The terminal device determines an adjustment amount of the PUSCH transmit power according to the number of PRACH repetition transmissions included in the target PRACH repetition transmission process and the PRACH transmit power of the PRACH repetition transmissions in the target PRACH repetition transmission process;

[0128] The terminal device determines the PUSCH transmit power in the random access process according to the adjustment amount of the PUSCH transmit power.

[0129] In some optional implementations, the terminal device determines the adjustment amount of the PUSCH transmit power based on the number of PRACH repetition transmissions included in the target PRACH repetition transmission process and the PRACH transmit power of the PRACH repetition transmission in the target PRACH repetition transmission process, including:

[0130] The terminal device determines a power adjustment amount related to the number of PRACH repetition transmissions and the PRACH transmit power according to the number of PRACH repetition transmissions included in the target PRACH repetition transmission process and the PRACH transmit power of the PRACH repetition transmissions in the target PRACH repetition transmission process;

[0131] The terminal device determines the adjustment amount of the PUSCH transmission power according to the power adjustment amount related to the number of PRACH retransmissions and the PRACH transmission power.

[0132] In some optional implementations, the correspondence between the number of PRACH retransmissions and the PRACH transmit power and the power adjustment amount is agreed upon by a protocol, or the correspondence between the number of PRACH retransmissions and the PRACH transmit power and the power adjustment amount is configured by a network device.

[0133] In some optional implementations, the correspondence between the number of PRACH repetition transmissions and the power adjustment amount may also be determined based on a preset rule, which may be a function, a table, or the like.

[0134] Specifically, in Example 3, in order to achieve a coverage level similar to that of PRACH, the transmit power of Msg3 PUSCH can refer to both the number of PRACH repeated transmissions and the power of PRACH in the PRACH repeated transmissions. Specifically, the parameter f(i) in the above formula 2 is set to ΔP rep +δ msg2 , where ΔP rep is the power adjustment value related to the number of PRACH retransmissions and the PRACH transmission power. rep It can be calculated by the number of PRACH retransmissions S included in the target PRACH retransmission process and the PRACH transmit power P of the PRACH retransmission during the target PRACH retransmission process, such as ΔP rep =S*P, or ΔP rep =α*S*P, where α is the adjustment coefficient and the range of α is between 0-1.

[0135] In embodiment 4, the first information is the number of times the PRACH retransmission process is executed, that is, the terminal device determines the transmission power of the PUSCH in the random access process according to the number of times the PRACH retransmission process is executed.

[0136] It should be noted that during the random access process, the network will configure the maximum number of PRACH transmissions. When the PRACH transmission reaches the maximum number and the network's RAR is still not received, the random access process is considered to have failed. The maximum number of transmissions is configured through the information element preamble maximum transmission number (preambleTransMax), and the values ​​of preamble maximum transmission number (preambleTransMax) include 3, 4, 5, 6, 7, 8, 10, 20, 50, 100, 200. For each PRACH transmission, the parameter PREAMBLE_POWER_RAMPING_COUNTER is increased by 1. Specifically, in the random access process based on PRACH repeated transmission, the terminal device may perform multiple PRACH repeated transmission processes until it receives the RAR sent by the network. When PRACH repeated transmission is adopted, whether to end the random access process can be determined based on whether the number of executed PRACH repeated transmission processes reaches the configured maximum value. Therefore, each PRACH retransmission process corresponds to a count parameter value. The count parameter starts from 1, and the count parameter increases by 1 each time a PRACH retransmission process is performed.

[0137] In some optional implementations of Example 4, the terminal device determines the transmission power of the PUSCH in the random access process based on the number of times the PRACH retransmission process is executed; wherein the number of times the PRACH retransmission process is executed is determined based on the target PRACH retransmission process, and the target PRACH retransmission process is a PRACH retransmission process responded by the network through RAR in at least one PRACH retransmission process.

[0138] In some optional implementations, the terminal device determines the transmit power of the PUSCH in the random access process according to the number of times the PRACH retransmission process is performed, including:

[0139] The terminal device determines an adjustment amount of the PUSCH transmit power according to the number of times the PRACH repeated transmission process is performed;

[0140] The terminal device determines the PUSCH transmit power in the random access process according to the adjustment amount of the PUSCH transmit power.

[0141] In some optional implementations, the terminal device determines, based on the number of times the PRACH retransmission process is performed, an adjustment amount for the PUSCH transmit power, including:

[0142] The terminal device determines the power adjustment amount related to the number of times the PRACH repeated transmission process is executed based on the number of times the PRACH repeated transmission process is executed; and the terminal device determines the adjustment amount of the PUSCH transmission power based on the power adjustment amount related to the number of times the PRACH repeated transmission process is executed.

[0143] In some optional implementations, the correspondence between the number of times the PRACH repeated transmission process is executed and the power adjustment amount is agreed upon by a protocol, or the correspondence between the number of times the PRACH repeated transmission process is executed and the power adjustment amount is configured by a network device.

[0144] In some optional implementations, the correspondence between the number of times the PRACH retransmission process is performed and the power adjustment amount may also be determined based on a preset rule, which may be a function, a table, or the like.

[0145] Specifically, in embodiment 4, the PRACH retransmission process responded by the network corresponds to a count parameter value. The power of Msg3PUSCH can refer to the count parameter value corresponding to the PRACH retransmission process responded by the network to determine the transmit power. Specifically, for example, the parameter f(i) in the above formula 2 is set to ΔP rep +δ msg2 , where ΔP rep The power adjustment amount related to the value of the counting parameter corresponding to the PRACH repeated transmission process responded by the network.

[0146] In embodiment 5, the first information is information indicated in the RAR, that is, the terminal device determines the transmit power of the PUSCH in the random access process according to the information indicated in the RAR.

[0147] In some optional implementations of Example 5, the terminal device determines the transmission power of the PUSCH in the random access process based on the information indicated in the RAR corresponding to the target PRACH repeated transmission process; wherein the information indicated in the RAR is the parameter N, the value of N represents the Nth PRACH transmission in the target PRACH repeated transmission process, and N is a positive integer.

[0148] Optionally, the network successfully detects the preamble in the Nth PRACH transmission during repeated transmission of the target PRACH. That is, the network can successfully detect the preamble by combining and receiving the first N PRACH transmissions during repeated transmission of the target PRACH. The transmit power of the first N PRACH transmissions represents a transmission parameter that satisfies PRACH coverage.

[0149] In some optional implementations, the terminal device determines the transmit power of the PUSCH in the random access process according to information indicated in the RAR corresponding to the target PRACH repeated transmission process, including:

[0150] The terminal device determines an adjustment amount of the PUSCH transmit power according to the value of N;

[0151] The terminal device determines the PUSCH transmit power in the random access process according to the adjustment amount of the PUSCH transmit power.

[0152] In some optional implementations, the terminal device determines, based on the value of N, an adjustment amount for the PUSCH transmit power, including:

[0153] The terminal device determines a power adjustment amount related to the number of PRACH repetition transmissions according to the value of N;

[0154] The terminal device determines the adjustment amount of the PUSCH transmission power based on the power adjustment amount related to the number of PRACH repeated transmissions.

[0155] In some optional implementations, the correspondence between the number of PRACH repetition transmissions and the power adjustment amount is agreed upon by a protocol, or the correspondence between the number of PRACH repetition transmissions and the power adjustment amount is configured by a network device.

[0156] In some optional implementations, the correspondence between the number of PRACH repetition transmissions and the power adjustment amount may also be determined based on a preset rule, which may be a function, a table, or the like.

[0157] Specifically, in Example 5, when the network responds to the RAR, the corresponding preamble information is indicated to the terminal device. For example, the RAR indicates the number of PRACH transmissions in a PRACH repetition transmission process. The power of Msg3 PUSCH can be calculated based on the number information and the power information of the indicated PRACH. For specific methods, please refer to Examples 1-3. Among them, the number information corresponds to the sequence number of the PRACH transmission indicated by the RAR, which indicates the number of PRACH transmissions in the PRACH repetition transmission process, that is, how many PRACH repetitions have been completed as of the end of the PRACH transmission.

[0158] In embodiment 6, the first information is a power offset parameter related to PRACH repeated transmission, that is, the terminal device determines the transmission power of the PUSCH in the random access process according to the power offset parameter related to PRACH repeated transmission.

[0159] It should be noted that a power offset parameter related to PRACH repeated transmission can be set, wherein the power offset parameter is a power offset parameter corresponding to PRACH repeated transmission added to the formula for calculating Msg3 PUSCH power (ie, the above formula 2).

[0160] In some optional implementations of Example 6, the terminal device determines the transmit power of the PUSCH in the random access process according to the power offset parameter related to the PRACH repeated transmission.

[0161] In some optional implementations, the terminal device determines the transmit power of the PUSCH in the random access process according to the power offset parameter related to the PRACH repeated transmission, including:

[0162] The terminal device determines the power related to the PRACH repeated transmission according to the power offset parameter related to the PRACH repeated transmission;

[0163] The terminal device determines the transmission power of the PUSCH in the random access process based on the power related to the PRACH repeated transmission.

[0164] It should be noted that in the above formula 2, Po=P O_PRE +Δ Rep_PREAMBLE_Msg3 , P O_PRE is the target receiving power of the Preamble, Δ Rep_PREAMBLE_Msg3 It is the power offset parameter of Msg3, which is the power offset parameter related to PRACH repeated transmission.

[0165] In this embodiment, the power associated with PRACH repetitive transmission can be represented by Po, where Po=P O_PRE +Δ Rep_PREAMBLE_Msg3 +Δ PRE , Δ Rep_PREAMBLE_Msg3 is the power bias parameter of Msg3, Δ PRE is the power offset parameter related to PRACH repeated transmission. That is, the power offset parameter Δ related to PRACH repeated transmission is added on the basis of Po in the above formula 2. PRE .

[0166] In some optional implementations, Po in Example 6 can also be applied to the solutions of Examples 1 to 5. That is, the improvements to f(i) in Formula 2 in Examples 1 to 5 can also be combined with the solution of Example 6 to improve Po in Formula 2.

[0167] In some optional implementations, the terminal device receives first indication information, which is used to indicate whether the terminal device uses the solution in Example 6, that is, adjusting Po in the above formula 2 to: Po = P O_PRE +Δ Rep_PREAMBLE_Msg3 +Δ PRE .

[0168] Therefore, in an embodiment of the present application, the terminal device can determine the transmission power of the PUSCH in the random access process based on the number of PRACH repeated transmissions, the PRACH transmission power in the PRACH repeated transmissions, the number of times the PRACH repeated transmission process is executed, the information indicated in the RAR, and at least one of the power bias parameters related to the PRACH repeated transmissions. The transmission power of the PUSCH in the random access process can be determined more reasonably, thereby improving the transmission performance of the PUSCH in the random access process.

[0169] The above, in combination with Figures 3 to 4, describes in detail the terminal side embodiment of the present application. The following, in combination with Figure 5, describes in detail the network side embodiment of the present application. It should be understood that the network side embodiment and the terminal side embodiment correspond to each other, and similar descriptions can refer to the terminal side embodiment.
