[0144] In some embodiments, before the first information, the reference signal power indicated by the first information already exists, and the current first information is used to update the reference signal power. It can also be understood that the reference signal power indicated by the current first information is an updated value.

[0145] In some embodiments, the first information is any one of DCI (Downlink Control Information), MAC CE (Media Access Control Control Element), and RRC (Radio Resource Control). In some embodiments, the above embodiment can also be understood as the signaling carrying / containing the first information is any one of DCI, MAC CE, and RRC, or a combination of multiple thereof. In some embodiments, the above embodiment can also be understood as the first information being sent via any one of DCI, MAC CE, and RRC, or a combination of multiple thereof.

[0146] In some embodiments, the name of the first information is not limited, and can be, for example, indication information, downlink information, power information, etc.

[0147] In some embodiments, the first information includes at least one of the following:

[0148] (1) First power.

[0149] In some embodiments, the first power is the power of the first reference signal. In some embodiments, the first power is used to indicate the transmit power of the first reference signal transmitted by the network device. In some embodiments, the name of the first power is not limited. For example, it can be the first transmit power for transmitting the first reference signal or the first reference signal power for transmitting the first reference signal.

[0150] (2) Second power.

[0151] In some embodiments, the second power is the power of the second reference signal. In some embodiments, the second power is used to indicate the transmit power of the second reference signal transmitted by the network device. In some embodiments, the name of the second power is not limited. For example, it can be the second transmit power for transmitting the second reference signal or the second reference signal power for transmitting the second reference signal.

[0152] (3) First power difference.

[0153] In some embodiments, the first power difference is a difference between the first power and the second power.

[0154] In some embodiments, when the first power and a first power difference between the first power and the second power exist, the second power can be determined by the difference between the first power and the first power difference. In some embodiments, when the first information carries the first power, the second power can be determined based on the first power difference.

[0155] In some embodiments, when the second power and a first power difference between the first power and the second power exist, the first power can be determined by the difference between the second power and the first power difference. In some embodiments, when the first information carries the second power, the first power can be determined based on the first power difference.

[0156] (4) Second power difference.

[0157] In some embodiments, the second power difference is the difference between the first power and the power of the first reference signal at the previous moment. In some embodiments, the power of the first reference signal at the previous moment refers to the power of the first reference signal used most recently before the power of the currently used first reference signal. For example, if the power of the first reference signal used by the terminal at the first moment is power 1, and the power of the first reference signal used at the second moment is power 2, and the first moment is the moment before the second moment, then the second power difference is the difference between power 2 and power 1.

[0158] In the embodiment of the present disclosure, the power of the first reference signal at the last moment is known, and the first power can be determined according to the difference between the power of the first reference signal at the last moment and the second power difference.

[0159] In some embodiments, the time interval between the first power at a current moment and the power of the first reference signal at a previous moment is a certain duration. Optionally, the certain duration refers to the time interval between two adjacent first messages indicating the second power difference by the network device. Alternatively, the certain duration refers to the time interval between the first first message indicating the first power and the next first message indicating the second power difference by the network device.

[0160] It should be noted that, in the embodiment of the present disclosure, the information carried in the two first messages at different times may be different.

[0161] (5) The third power difference.

[0162] In some embodiments, the third power difference is the difference between the second power and the power of the second reference signal at the previous moment. In some embodiments, the power of the second reference signal at the previous moment refers to the power of the second reference signal used most recently before the power of the currently used second reference signal. For example, if the power of the second reference signal used by the terminal at a first moment is power 3, and the power of the second reference signal used at a second moment is power 4, and the first moment is the moment before the second moment, then the second power difference is the difference between power 4 and power 3.

[0163] In the embodiment of the present disclosure, the power of the second reference signal at the last moment is known, and the second power can be determined according to the difference between the power of the second reference signal at the last moment and the third power difference.

[0164] In some embodiments, the time interval between the second power at the current moment and the power of the second reference signal at the previous moment is a certain duration. Optionally, the certain duration refers to the time interval between when the network device indicates the third power difference through two adjacent first messages. Alternatively, the certain duration refers to the time interval between when the network device indicates the second power through a first first message and when the network device indicates the third power difference through a next first message.

[0165] It should be noted that, in the embodiment of the present disclosure, the information carried in the two first messages at different times may be different.

[0166] (6) A fourth power difference value, where the fourth power difference value refers to a power difference value between the power of the first reference signal or the second reference signal and the power of the reference signal corresponding to the previous moment.

[0167] In some embodiments, the fourth power difference is shared by the first reference signal or the second reference signal. That is, the fourth power difference simultaneously indicates the difference between the power of the first reference signal and the first reference signal corresponding to the previous moment, and the difference between the power of the second reference signal and the second reference signal corresponding to the previous moment. Alternatively, it can be understood that the difference between the power of the first reference signal and the first reference signal corresponding to the previous moment, and the difference between the power of the second reference signal and the second reference signal corresponding to the previous moment, are the same, and are both the fourth power difference.

[0168] The first reference signal and the second reference signal are different. Alternatively, it can be understood that the first reference signal and the second reference signal are different types of signals.

[0169] In some embodiments, the first reference signal is SSB, and the second reference information is CSI-RS; or, the first reference signal is CSI-RS, and the second reference information is SSB.

[0170] It should be noted that the embodiments of the present disclosure involve different types of power differences. The power differences in the embodiments of the present disclosure can be positive or negative. Therefore, when the power is known, if the power difference is subtracted from the known power, the power obtained can be greater than or less than the known power. Alternatively, it can be understood that, based on the known power and the power difference, the difference between the known power and the power difference is obtained to obtain the unknown power.

[0171] In combination with the above embodiment, the following mainly describes the case where the first reference signal is SSB and the second reference signal is CSI-RS as an example.

[0172] The first information includes at least one of the following: the first power of SSB, the second power of CSI-RS, the first power difference between the first power of SSB and the second power of CSI-RS, the second power difference between the first power of SSB and the power of SSB at the previous moment, the third power difference between the second power of CSI-RS and the power of CSI-RS at the previous moment, the third power difference between the second power of CSI-RS and the power of CSI-RS at the previous moment, and the fourth power difference.

[0173] (1) The first power of SSB.

[0174] In some embodiments, if the first information includes multiple SSB identifiers, different SSB identifiers may correspond to different first powers. In some embodiments, the SSB may also include multiple types of reference signals, such as PSS (primary synchronization signal), SSS (secondary synchronization signal), and DMRS in PBCH. It can also be understood that the first power of the SSB is at least one of the first power of the PSS included in the SSB, the first power of the SSS included in the SSB, or the first power of the DMRS in the PBCH included in the SSB.

[0175] (2) The second power of CSI-RS.

[0176] In some embodiments, if the first information includes multiple CSI-RS identifiers, different CSI-RS identifiers may correspond to different second powers.

[0177] (3) A first power difference between the first power of the SSB and the second power of the CSI-RS.

[0178] (4) A second power difference between the first power of the SSB and the power of the SSB at the previous moment.

[0179] In some embodiments, the power of the SSB at the previous moment can also be understood as the first power received most recently before the terminal receives the first power this time.

[0180] (5) A third power difference between the second power of the CSI-RS and the power of the CSI-RS at the previous moment.

[0181] In some embodiments, the power of the CSI-RS at the previous moment may also be understood as the second power or the difference between the first power and the first power most recently received by the terminal before the terminal receives the second power this time.

[0182] (6) A fourth power difference value, where the fourth power difference value refers to a power difference value between the power of the SSB or CSI-RS and the power of the reference signal corresponding to the previous moment.

[0183] In some embodiments, the fourth power difference is shared by the SSB or the CSI-RS. That is, the fourth power difference simultaneously indicates the difference between the power of the SSB and the SSB corresponding to the previous moment, and the difference between the power of the CSI-RS and the CSI-RS corresponding to the previous moment. Alternatively, it can also be understood that the difference between the power of the SSB and the SSB corresponding to the previous moment, and the difference between the power of the CSI-RS and the CSI-RS corresponding to the previous moment are the same, both being the fourth power difference.

[0184] It should be noted that, in the embodiment of the present disclosure, the network device may send the first information to the terminal multiple times, and the content included in the first information sent each time may be the same or different, which is not limited in the embodiment of the present disclosure.

[0185] In combination with the above embodiment, the first reference signal is CSI-RS and the second reference signal is SSB as an example for description:

[0186] The first information includes at least one of the following: the first power of CSI-RS, the second power of SSB, the first power difference between the first power of CSI-RS and the second power of SSB, the second power difference between the first power of CSI-RS and the power of CSI-RS at the previous moment, the third power difference between the second power of SSB and the power of SSB at the previous moment, the third power difference between the second power of SSB and the power of SSB at the previous moment, and the fourth power difference.

[0187] (1) The first power of CSI-RS.

[0188] In some embodiments, if the first information includes multiple CSI-RS identifiers, different CSI-RS identifiers may correspond to different first powers.

[0189] (2) Second power of SSB.

[0190] In some embodiments, if the first information includes multiple SSB identifiers, different SSB identifiers may correspond to different second powers. In some embodiments, the SSB may also include multiple types of reference signals, such as PSS (primary synchronization signal), SSS (secondary synchronization signal), and DMRS in PBCH. It can also be understood that the first power of the SSB is at least one of the second power of the PSS included in the SSB, the second power of the SSS included in the SSB, or the second power of the DMRS in the PBCH included in the SSB.

[0191] (3) A first power difference between the first power of the CSI-RS and the second power of the SSB.

[0194] (6) A fourth power difference value, where the fourth power difference value refers to a power difference value between the power of the CSI-RS or SSB and the power of the reference signal corresponding to the previous moment.

[0195] It should be noted that the embodiments of the present disclosure relate to SSB and CSI-RS, wherein the reference signal power of the SSB can be indicated by ss-PBCH-BlockPower (a signal power signaling), and the reference signal power of the CSI-RS can be determined by the difference indicated by powerControlOffsetSS (a signaling for indicating the difference) and the reference signal power of the SSB. In some embodiments, this means that the first information includes ss-PBCH-BlockPower and powerControlOffsetSS. In some embodiments, the network device can update the reference signal power of the SSB by updating the SIB.

[0196] In some embodiments, the network device broadcasts the reference signal power of SSB as P0 through SIB message, and updates the reference signal power information of SSB as P0-update through UE-dediacted RRC signaling. After the UE successfully receives the RRC signaling and / or the RRC signaling takes effect, the UE considers that the transmit power of SSB is P0-update.

[0197] In some embodiments, the network device broadcasts the reference signal power P0 of the SSB through the SIB message, and the base station indicates the power difference P1 between the SSB and the power value sent by the last SSB through MAC CE signaling. After the UE successfully receives the MAC CE signaling and / or this indication takes effect, the UE considers that the transmission power of the SSB is P0-P1.

[0198] In some embodiments, the network device broadcasts the reference signal power P0 of the SSB via a SIB message and configures the value of powerControlOffsetSS via UE-decoded RRC signaling. The UE considers the transmit power of the CSI-RS to be P0-powerControlOffsetSS. The base station then reconfigures the value of powerControlOffsetSS to powerControlOffsetSS-update via RRC reconfiguration. After the UE successfully receives the RRC signaling and / or the RRC signaling takes effect, the UE considers the transmit power of the CSI-RS to be P0-ppowerControlOffsetSS-update.

[0199] In some embodiments, the network device broadcasts the reference signal power P0 of the SSB via a SIB message and configures the value of powerControlOffsetSS via UE-decoded RRC signaling. The base station then indicates the power difference P1 between the CSI-RS and the power value of the last CSI-RS transmission via MAC CE signaling. After the UE successfully receives the MAC CE signaling and / or the current indication takes effect, the UE considers the CSI-RS transmit power to be P0-powerControlOffsetSS-P1.

[0200] In some embodiments, the network device broadcasts the reference signal power P0 of the SSB through an SIB message and configures the value of powerControlOffsetSS through UE-decoded RRC signaling. The base station then indicates the power difference P1 of the downlink reference signal transmit power through group common DCI signaling. After the UE successfully receives the DCI signaling and / or this indication takes effect, the UE considers that the transmit power of the downlink reference signal SSB is P0-P1, and the transmit power of the downlink reference signal CSI-RS is P0-powerControlOffsetSS-P1.

[0201] The power values ​​and power differences mentioned in the above embodiments, such as P0, powerControlOffsetSS, P1, P0-update, powerControlOffsetSS-update, etc., can only distinguish between reference signal types such as CSI-RS type or SSB type, without distinguishing between reference signal IDs; they can also be for a specific CSI-RS index or a specific SSB index, for example, there is a power value and a corresponding power change value for SSB#1, and there is a power value and a corresponding power change value for SSB#2.

[0202] In some embodiments, the network device sends the first information. In some embodiments, the terminal receives the first information.

[0203] Step S2102: The terminal sends second information to the network device.

[0204] In some embodiments, the second information is used to indicate whether the first information is received. In some embodiments, the second information is used to indicate whether the first information is successfully received. In some embodiments, the second information is used to provide feedback on whether the first information is received.

[0205] In some embodiments, the name of the second information is not limited. For example, it can be feedback information, response information, etc. Optionally, the second information is HARQ information. For example, if the second information is HARQ-ACK, it indicates that the terminal has received the first information. For example, if the second information is HARQ-NACK, it indicates that the terminal has not received the first information.

[0206] In some embodiments, the first information takes effect after the first time period has elapsed after the second information is sent. In the disclosed embodiments, the first information has an effective time, that is, the first information takes effect at a specific time, and the terminal uses the reference signal power indicated by the first information after the effective time of the first information.

[0207] In one embodiment, the first information is carried by MAC CE signaling, and the UE feeds back the HARQ-ACK information for the PDSCH containing the MAC CE, then the effective time is from the time slot Where k is the time slot in which the UE sends PUCCH or PUSCH with HARQ-ACK information to the PDSCH providing the MAC CE. μ is the SCS configuration of the PUCCH or PUSCH determined in the time slot when the MAC CE command is applied, and k mac The number of time slots for the SCS configuration μ=0 provided by kmac. If k is not provided mac , then k mac =0.

[0208] In some embodiments, the first duration is predetermined by a communication protocol, or configured by a terminal, or configured by a network device, which is not limited in the embodiments of the present disclosure. For example, the first duration is 10ms (milliseconds), 20ms, 30ms, or other values, which are not limited in the embodiments of the present disclosure.

[0209] In some embodiments, the terminal sends the second information. In some embodiments, the network device receives the second information.

[0210] Step S2103: The terminal determines the transmission power of the uplink signal / uplink channel sent by the terminal based on the reference signal power.

[0211] In some embodiments, the uplink signal / uplink channel includes at least one of the following: PRACH; SRS; PUSCH; PUCCH.

[0212] Optionally, in some embodiments, after determining that BF is detected, the terminal determines the transmit power of the PARCH. After determining that BF is detected, the terminal may determine the power and offset of the downlink reference signal bound to the uplink power control of the PRACH, and then determine the transmit power of the PARCH based on the power and offset of the reference signal. After determining the transmit power of the PARCH, communication with the network device can be restored through BFR during the random access process. Optionally, the offset refers to any one of the power difference values ​​included in the first information in the above embodiment. For example, the offset refers to the second power difference value, the third power difference value, etc., which is not limited in the embodiments of the present disclosure.

[0213] Optionally, in some embodiments, when a terminal determines that an SRS needs to be transmitted, such as when performing uplink channel detection, the terminal needs to determine the transmit power of the SRS. The terminal calculates the downlink transmission loss based on the downlink reference signal bound to the uplink power control of the SRS, and then determines the transmit power of the SRS, thereby enabling the network to estimate uplink channel frequency domain information based on the SRS.

[0214] Optionally, in some embodiments, the terminal does need to send PUCCH, such as when it needs to request resources for uplink transmission, and determines the transmit power of PUCCH. Among them, if the terminal needs to perform uplink transmission, it needs to first request the resources required for uplink transmission from the network device, and then perform uplink transmission based on the requested resources. Therefore, the terminal calculates the downlink transmission loss based on the downlink reference signal bound to the uplink power control of PUCCH, and then determines the transmit power of PUCCH. After determining the transmit power of PUCCH, uplink transmission can be performed through the resources requested by PUCCH. Among them, the downlink reference signal bound to the uplink power control of SRS is configured by the network through RRC signaling. Among them, the downlink reference signal bound to the uplink power control of PUCCH is configured by the network through RRC signaling.

[0215] Optionally, in some embodiments, when the terminal determines that it needs to send uplink data to the network device, it determines the transmit power of the PUSCH. If the terminal has uplink data to send to the network device, it calculates the downlink transmission loss based on the downlink reference signal bound to the uplink power control of the PUSCH, and then determines the transmit power of the PUSCH. Based on the transmit power, the PUSCH carrying the uplink data is sent to the network device. The downlink reference signal bound to the uplink power control of the PUSCH is configured by the network through RRC signaling.

[0216] For example, if the uplink channel is a PRACH, the terminal calculates the downlink transmission loss based on the downlink reference signal bound to the PRACH uplink power control, and then determines the transmit power of the PRACH by the terminal. The downlink reference signal bound to the PRACH uplink power control is selected by the terminal based on the terminal's measurement results.

[0217] In some embodiments, the network device periodically sends SIB1, and the terminal can receive the SIB1 sent by the network device, which includes the first power of the SSB, that is, it indicates the transmit power of the SSB sent by the network device (the reference signal power indicated by the first information). In addition, the terminal can also access the network device. After accessing the network device, the network device can configure the downlink reference signal CSI-RS for uplink power control for the terminal and the first power difference included in the first information to indicate the power of the CSI-RS. Moreover, after accessing the network device, the network device can also indicate the subsequent third power difference of the CSI-RS (corresponding to the second reference signal being CSI-RS in the above embodiment) and / or the subsequent second power difference of the SSB. In the following operations, how to determine the transmit power of the CSI-RS and the transmit power of the uplink signal / uplink channel in different situations is explained.

[0218] The first: random access process: At this time, if the network device initiates random access through PDCCH or beam failure, the transmit power of the reference signal determined by the terminal at this time needs to be determined based on the transmit power of SSB, the first power difference and the third power difference of CSI-RS. During the random access process, the reference signal power at this time is the transmit power of SSB-the first power difference-the third power difference of CSI-RS. Furthermore, the difference between the power obtained by the terminal for measuring the reference signal and the transmit power of the reference signal is determined to determine the path loss, and then the power of the terminal to send PRACH is determined based on the path loss. For example, the transmit power of SSB is represented by ss-PBCH-BlockPower, the first power difference is represented by powerControlOffsetSS, and the third power difference of CSI-RS is represented by UE power offset value. Then, the power of the CSI-RS sent by the current network device is reference signal power = ss-PBCH-BlockPower-powerControlOffsetSS-UE power offset value.

[0219] The second type: PUSCH process: At this time, if the terminal needs to send data through PUSCH, the transmit power of the reference signal determined by the terminal needs to be determined based on the transmit power of the SSB, the first power difference, and the third power difference of the CSI-RS. During the random access process, the reference signal power at this time is the transmit power of the SSB - the first power difference - the third power difference of the CSI-RS. Furthermore, the path loss is determined by determining the difference between the power obtained by the terminal for measuring the reference signal and the transmit power of the reference signal, and then the power of the terminal to send PUSCH is determined based on the path loss.

[0220] The third type: SRS process: At this time, if the terminal needs to perform uplink channel estimation through SRS, the transmit power of the reference signal determined by the terminal needs to be determined based on the transmit power of the SSB, the first power difference, and the third power difference of the CSI-RS. During the random access process, the reference signal power at this time is the transmit power of the SSB - the first power difference - the third power difference of the CSI-RS. Furthermore, the path loss is determined by determining the difference between the power obtained by the terminal for measuring the reference signal and the transmit power of the reference signal, and then the power of the SRS sent by the terminal is determined based on the path loss.

[0221] The third type: PUCCH process: At this time, if the terminal needs to obtain uplink transmission resources through PUCCH, the transmit power of the reference signal determined by the terminal needs to be determined based on the transmit power of the SSB, the first power difference, and the third power difference of the CSI-RS. During the random access process, the reference signal power at this time is the transmit power of the SSB - the first power difference - the third power difference of the CSI-RS. Furthermore, the path loss is determined by determining the difference between the power obtained by the terminal for measuring the reference signal and the transmit power of the reference signal, and then the power of the terminal to send PUCCH is determined based on the path loss.

[0222] In some embodiments, sending an uplink channel in the embodiments of the present disclosure may also be understood as sending information carried in the uplink channel, or may also be understood as sending an uplink channel used to carry information.

[0223] In some embodiments, the reference signal power is used by the terminal to estimate the path loss of downlink transmission. In some embodiments, the path loss refers to the loss incurred when the reference signal is transmitted between the network device and the terminal. In some embodiments, the path loss refers to the loss incurred when the reference signal is transmitted between the network device and the terminal due to channel effects or radiation effects.

[0224] In some embodiments, the terminal estimates the path loss of downlink transmission based on the reference signal power, and further determines the transmit power of the uplink signal / uplink channel sent by the terminal based on the determined path loss.

[0225] Optionally, the terminal estimates the path loss of downlink transmission based on the reference signal power, and the transmission power of the uplink signal / uplink channel sent by the terminal is the sum of the reference signal power indicated by the network device and the path loss.

[0226] In some embodiments, the downlink transmission path loss is determined based on the difference between the reference signal power and the power obtained by the terminal receiving the reference signal. Optionally, the downlink transmission path loss refers to the difference between the reference signal power and the power obtained by the terminal receiving the reference signal. In some embodiments, if the uplink power path loss is 0, it indicates that the communication between the network device and the terminal is not affected and there is no signal loss.

[0227] It should be noted that, in one embodiment, the present application also involves the time at which the first information takes effect. If the first information currently received by the terminal is not yet effective, then when executing the above steps, the terminal should use the reference signal power before the first information was received to determine the path loss, and then determine the transmit power for the uplink signal / uplink channel based on the path loss. If the first information is received after the first information is effective, then when executing the above steps, the terminal should use the reference signal power indicated by the first information to determine the path loss, and then determine the transmit power for the uplink signal / uplink channel based on the path loss.

[0228] Step S2104: The terminal transmits the uplink signal / uplink channel based on the determined transmit power of the uplink signal / uplink channel.

[0229] In some embodiments, the terminal determines the transmit power of the uplink signal and transmits the uplink signal based on the determined transmit power of the uplink signal. In some embodiments, the terminal determines the transmit power of the uplink channel and transmits the uplink channel based on the determined transmit power of the uplink channel.

[0230] In the embodiment of the present disclosure, the terminal sends the uplink signal / uplink channel based on the determined transmission power of the uplink signal / uplink channel, and the subsequent network device can receive the uplink signal / uplink channel sent by the terminal.

[0231] In combination with the above embodiments, random access is used as an example to illustrate the embodiments of the present disclosure. See the following steps:

[0232] S21201: The network device periodically sends SIB1.

[0233] The SIB1 configures the transmission power of the reference signal sent by the network device.

[0234] S21202: Determine the path loss based on SIB1.

[0235] Among them, the method of determining the path loss in the embodiment of the present disclosure is similar to the method of determining the path loss in the above embodiment, and will not be repeated here.

[0236] In some embodiments, the transmission power of the reference signal sent by the network device configured in SIB1 is ss-PBCH-BlockPower. Optionally, the ss-PBCH-BlockPower refers to the average EPRE (energy per resource element) of the resource elements.

[0237] In some embodiments, ss-PBCH-BlockPower is used to determine the power of Msg1.

[0238] Optionally, referenceSignalPower (the transmission power of the reference signal sent by the corresponding network device when calculating the path loss) is determined based on ss-PBCH-BlockPower, and then the path loss is determined based on referenceSignalPower and the power obtained by the terminal measuring the reference signal, and then the power of MSG1 is determined.

[0239] S21203: The terminal initiates a random access process based on the path loss to access the network device.

[0240] S21204: The network device sends third information, where the third information is used to determine an uplink power offset.

[0241] In some embodiments, the third information is MAC CE information. Optionally, the uplink power offset refers to any one of the power difference values ​​included in the first information in the above embodiment. For example, the offset refers to the second power difference value, the third power difference value, etc., which is not limited in the embodiments of the present disclosure.

[0242] S21205: The terminal determines the power of transmitting the uplink signal / uplink channel based on the initial reference signal power of SIB1 and the uplink power offset determined by the third information.

[0243] The following describes the solution of the present disclosure by way of examples.

[0244] In some embodiments, the terminal can obtain the reference signal power (ss-PBCH-BlockPower) corresponding to the SSB through the first information. During the initial access process, the terminal determines that the transmission power of the SSB sent by the network device is ss-PBCH-BlockPower. After the terminal accesses the network device, the network device can configure a periodic CSI-RS and a first power difference (powerControlOffsetSS) between the first power (ss-PBCH-BlockPower) and the second power for the terminal, and the network device will also indicate the second power difference (power offset value) between the first power and the power of the CSI-RS at the previous moment through the first information. The terminal then determines that the transmission power of the CSI-RS after indicating the second power difference is reference signal power = ss-PBCH-BlockPower-powerControlOffsetSS-UE power offset value.

[0245] In some embodiments, after the terminal receives the network device, the network can configure a periodic CSI-RS and a first power difference (powerControlOffsetSS) between the first power and the second power for the terminal, and the network device will also indicate the second power difference (UE power offset value#1 and UE power offset value#2) between the first power and the power of the CSI-RS at the previous moment through the first information. Then, for PRACH transmission initiated by PDCCH order, PRACH transmission initiated by beam failure recovery, PUSCH and PUCCH transmission, the terminal determines that the transmission power of the CSI-RS after indicating the second power difference is reference signal power = ss-PBCH-BlockPower-powerControlOffsetSS-UE power offset value#2. - If the UE is configured with pathlossReferenceRSs, the UE determines whether the RS is SSB or CSI-TS.

[0261] It should be noted that the embodiment of FIG. 2A in the above embodiment is an example of an embodiment of the present application. In another embodiment, the information type included in the first information is further explained. Referring to FIG. 2B , FIG. 2B is a flow chart of a communication method according to an embodiment of the present disclosure, as applied to a terminal. As shown in FIG. 2B , the method includes:

[0262] Step S2201: The network device sends configuration information to the terminal.

[0263] In some embodiments, the configuration information is used to configure the power of the SSB for the terminal, or the configuration information is also used to configure the power of the CSI-RS for the terminal. The power of the SSB and the power of the CSI-RS refer to the power of the SSB or CSI-RS sent by the network device to the terminal.

[0264] It should be noted that if the configuration information is used to configure the SSB power for the terminal, the configuration information is sent during the random access process of the terminal. Optionally, the configuration information is information carrying a random access preamble or access confirmation information sent by the terminal during the random access process. Optionally, the configuration information can also be referred to as information for configuring the initial SSB power for the terminal. Optionally, the name of the configuration information is not limited. For example, it can be indication information, random access information, etc.

[0265] It should be noted that if the configuration information is used to configure the CSI-RS power for the terminal, the configuration information is sent after the terminal is in the connected state. Alternatively, it can be understood that the configuration information is sent after the terminal successfully accesses the network device after completing random access. Optionally, the configuration information can also be referred to as information used to configure the initial CSI-RS power for the terminal.

[0266] It should be noted that the configuration information in the embodiment of the present disclosure can also be referred to as the first information. The difference between the first information and the following step S2202 is that the first information in step S2201 includes the first power or the second power, that is, the power of SSB or the power of CSI-RS, which is used to indicate the initial SSB power or CSI-RS power to the terminal.

[0273] In some embodiments, the first information is actually information indicating a new power of the reference signal through the power difference. Alternatively, it can also be understood that the first information is information for adjusting the transmit power of the reference signal through the power difference.

[0274] It should be noted that in the embodiment of the present disclosure, after the network device sends the first information to the terminal, the power difference indicated by the first information is used by the network device to update the power of the reference signal through the indicated power difference, that is, the power of the reference signal after the first information needs to be determined based on the power difference.

[0275] Step S2203: The terminal sends second information to the network device.

[0276] Step S2204: The terminal determines the transmission power of the uplink signal / uplink channel sent by the terminal based on the reference signal power.

[0277] In the above embodiment, after the network device configures the initial SSB or CSI-RS power for the terminal, it adjusts the power of the SSB or CSI-RS according to the power difference indicated by the first information, ensuring that the power used by the network device when sending the reference signal can be flexibly adjusted, ensuring the flexibility of the indication, and thus ensuring the accuracy of the indication.

[0278] It should be noted that the first information in step S2202 of the embodiment of FIG. 2A is used as an example to explain power adjustment using a power difference. In another embodiment, the first information may include only the first power or the second power. The first power or second power included in the new first information is used to replace the previous first power or second power, or it can also be understood as updating the previous first power or second power.

[0279] In some embodiments, the embodiment of FIG. 2A in the above embodiment is an example of an embodiment of the present application. In another embodiment, the first information in the embodiment of FIG. 2A includes only at least one of the first power or the second power, and the first power or the second power is used to directly indicate the power required for the network device to subsequently send the reference signal.
