step 201, determining the power of target transmission according to target information;
step 202, sending the target transmission according to the determined power;

In the embodiment of the present application, the power control on the target transmission includes: and determining the path loss and the power control indication of the power of the target transmission, and determining the power of the target transmission based on the power control indication and the path loss. The above-mentioned determining the power of the target transmission based on the target information may be understood to include at least one of:
determining the path loss of the power transmitted by the target according to the target path loss;
and determining a power control instruction of target transmission according to the target power control instruction.
The way for determining the path loss of the power of the target transmission according to the target path loss may be set according to actual needs, for example, in some embodiments, it may be understood that: the target path loss is used as the path loss of the power control of the target transmission, namely, the target path loss is used as the path loss of the power control of the target object.
For example, in some embodiments, it may be understood that the power control instruction applied to power control of the target transmission is the target power control instruction, that is, the target power control instruction is used as a power control instruction of a target object.
Optionally, in some embodiments, the Uplink Data may include a Transport Block (TB), a Medium Access Control Protocol Data Unit (MAC PDU) or a Physical Uplink Shared Channel (PUSCH). That is, the above-mentioned target transmission may be understood as retransmission of a certain TB, MAC PDU or PUSCH.
Optionally, in some embodiments, the uplink data may include message 3(msg 3). That is, the above target transmission may be understood as msg3 retransmission. It is noted that in some embodiments, the retransmission of a certain TB, MAC PDU, PUSCH may include msg3 retransmission.
The above signals may be understood as Sounding Reference Signal (SRS), positioning Reference Signal (SRS), or the like. That is, the above target transmission may be understood as SRS retransmission or positioning reference signal retransmission.
The target reference Signal may be any reference Signal configured by the network for the terminal, and optionally, the reference Signal may be a general conceptual reference Signal, or may be a physical Signal used for reference, for example, a Synchronization Signal and PBCH block (SSB). The terminal may first perform path loss measurement based on the target reference signal to obtain path loss, and when performing target transmission, directly obtain path loss corresponding to the target reference signal to determine path loss of target transmission, thereby calculating power of target transmission.
The target power control command may be understood as a control command for scheduling retransmission of msg3, where the target power control command may carry a power control instruction, and specifically, determining the target power control instruction according to the N target power control commands may be understood as obtaining the target power control according to the power control instructions of one or more target power control commands that the N target power control commands satisfy a preset condition.

In the embodiment of the application, the power of target transmission is determined according to the target information; transmitting the target transmission according to the determined power; the target information includes at least one of a target path loss and a target power control instruction, the target transmission includes retransmission of a target object, the target object includes uplink data or signals, the target path loss is determined according to path loss measurement performed on a target reference signal, and the target power control instruction is determined according to N target power control commands. Therefore, the method for determining the power of the uplink data or signal retransmission is determined in the embodiment of the application, and the reliability of the uplink data or signal retransmission is ensured.
Optionally, in an embodiment, the target reference signal is the same as a reference signal used for the initial path loss measurement of the message 3;
in this embodiment of the application, the reference signal used for the path loss measurement of the initial transmission of the message 3 may be an RS in a general concept, or may be a physical signal used for reference, such as an SSB. The reference signal originally transmitted by the msg3 is used as the retransmitted reference signal, so that the consistency of the originally transmitted path loss and the retransmitted path loss can be ensured, and the accuracy of determining the retransmitted path loss is improved. Therefore, the method can avoid that the difference between the initial transmission path loss and the retransmission path loss is large, the power continuity of a plurality of msg3 initial transmissions/retransmissions corresponding to the Random Access Response (RAR) is damaged, and the frequent Random Access failure is caused.
Optionally, in some embodiments, when the uplink data is msg3, the target reference signal is the same as a reference signal corresponding to a physical random access channel transmission.
In this embodiment of the application, the Reference Signal corresponding to the physical Random Access Channel transmission may be a Synchronization Signal Block (SSB) or a Channel State Information Reference Signal (CSI-RS) of a Random Access Channel (RACH), that is, the SSB or CSI-RS of the RACH may be selected as target Reference Information, and the path loss retransmitted by the msg3 is determined.
Optionally, in some embodiments, the N target power control commands satisfy at least one of:
when N is equal to 1, the target power control command is a first control command, where the first control command is used to schedule a current retransmission of the target object;
and in the case that N is greater than 1, the target power control command comprises the first control command and at least one second control command, the at least one second control command is at least part of L control commands, the L control commands are control commands except the first control command in the control commands for scheduling retransmission of the target object, and L is a positive integer.
In the embodiment of the present application, the second control command may be a command before the first control command, for example, when the first control command is a control command scheduled to be retransmitted for the nth msg3, the second control command may be part or all of the control commands scheduled to be retransmitted for the first n-1 msg 3. The target power control indication of the current msg3 retransmission can be determined by combining a plurality of power control commands for scheduling msg3 retransmission, so that the accuracy of power control on the current msg3 can be improved, and the success probability of the random access process is improved.
When the value of N is 0, it means that the target power control command is ignored, or the power control instruction in the target power control command is not used, for example, the target power control instruction is a default value of the protocol.
Optionally, in some embodiments, the N target power control commands include at least two third control commands, where beams, directions, or spatial relationships of target objects corresponding to the at least two third control commands are the same, or target objects of the at least two third control commands correspond to preset beams, preset directions, or preset spatial relationships.
Optionally, in some embodiments, the target power control command may be DCI scheduling uplink. In some embodiments, the target power control command is a control command indicating a power control value.
The target power control command satisfies at least one of:
the target power control command is any control command;
the target power control command is a preset control command;
the physical uplink shared channel PUSCH scheduled by the target power control command corresponds to a preset power adjustment state;
the target power control command corresponds to a random access response RAR;
the target power control command is used to schedule the target transmission;
the target power control command is used to schedule the target object retransmission.
In the embodiment of the present application, the target power control command is any control command, and it may be understood that the control command scrambled by any Radio Network Temporary Identifier (RNTI), for example, may include a control command scrambled by a specific cell Radio Network Temporary Identifier (cell RNTI, C-RNTI), or a specific Temporary cell Radio Network Temporary Identifier (TC-RNTI), or a configuration scheduled Radio Network Temporary Identifier (CS-RNTI), or a Radio Network Temporary Identifier (Modulation and coding scheme RNTI, MCS-RNTI).
The preset control command may be understood as a control command for a specific identifier and/or a specific format, for example, a control command scrambled by TC-RNTI, a DCI format (format)0-0, and further, a DCI format 0-0 scrambled by TC-RNTI.
The preset power adjustment state may be a specific power adjustment state, such as a power control adjustment state l.
Optionally, in a case that the target power control command is a control command for scheduling retransmission of the message 3, for a target transmission of msg3 retransmission, the corresponding target power control indication is a power control value of a DCI indication scheduling the msg3 retransmission, that is, the target transmission power is determined based on the power control value of the DCI indication scheduling the msg 3.
It should be noted that, the determination manner of the target power control indication may be set according to actual needs, for example, in some embodiments, the target power control indication may include any one of the following:
a preset power control value indicated by the control command;
the sum of the power control values indicated by a plurality of preset control commands;
a preset power control value.
In the embodiment of the present application, the power control value may be a Transmission Power Control (TPC) command (value), for example, a TPC command value indicated by a TPC command field.
For the case that the target power control indication includes the sum of the power control values indicated by a plurality of preset control commands, optionally, in this embodiment, if there are a plurality of preset control commands, the sum of the power control values indicated by these control commands is used to determine the power of the target transmission. The preset control commands are downlink control information for scheduling retransmission of the target object. For example, a first control command may be included that schedules a retransmission of the current msg3, and a second control command that schedules a retransmission of the current msg3 that was previously msg 3. Taking DCI as an example, a plurality of preset control commands schedule DCI retransmitted by msg3, and DCI retransmitted by msg3 before the DCI. In the embodiment of the present application, it is assumed that for the second msg3 retransmission scheduled by the base station for the target transmission, the preset control command is DCI scheduling the first msg3 retransmission and DCI scheduling the second msg3 retransmission, and the target power control indication is the sum of power control values carried by the two DCIs.
The preset power control value may be 0, that is, the terminal ignores that the power control value in the power control command is retransmitted for the target transmission msg3, and the target power control indication is 0, no matter whether the preset control command carries the power control value at this time. In this embodiment, when the preset power control value may be 0, for the msg3 retransmission serving as the target transmission, the terminal ignores the TPC command value in the preset control command, and/or the target power control indication is 0.
In order to better understand the implementation of the present application, the following detailed description is made of some embodiments.
The first embodiment is as follows: retransmitted for the target transmission as msg 3.
In case 1, if the PUSCH initial transmission and/or retransmission corresponds to the RAR uplink grant, the reference signal resource index used by the UE is the same as the reference signal resource index corresponding to the PRACH transmission.
In case 2, except for PUSCH retransmission corresponding to RAR uplink grant, if PUSCH transmission is scheduled by DCI format 0_0, and if UE is provided with air interface setting of PUCCH resource of lowest index for each carrier f and activated uplink fractional bandwidth b of serving cell c by PUCCH-spatial relationship info, reference signal resource index used by UE is the same as reference signal resource index corresponding to PUCCH transmission of lowest index PUCCH resource.
In case 3, except for PUSCH retransmission corresponding to RAR uplink grant, if PUSCH transmission is scheduled by DCI format 0_0 and UE is not provided with air interface setting for PUCCH transmission, or PUSCH transmission is scheduled by DCI format 0_1 not including SRI indication field, or if SRI-PUSCH-PowerControl is not provided to UE, UE determines reference signal index according to PUSCH-pathlossrireferencers-Id ═ 0, where the reference signal resource is in serving cell c or in serving cell indicated by the value of pathlossreserenumbering (if provided).
