Optionally, different beams cover different areas, and the number of services using the beams varies for different areas, so beams need to be dynamically allocated based on the services.

[0134] In some embodiments, the present disclosure relates to energy and link bandwidth limitations. Optionally, taking capability as an example, each beam and each frequency coverage segment is related to power. Optionally, each beam consumes a certain amount of power. For example, taking a beam corresponding to 5 MHz (megahertz) as an example, the relay device can send beams of 10 different wavelengths, each of which occupies 5 MHz, and the occupied frequency bands can be the same or different. For another example, the relay device can send beams of 8 different wavelengths, 7 of which are 5 MHz and one is 15 MHz.

[0135] FIG2 is an interactive diagram of a communication method according to an embodiment of the present disclosure. As shown in FIG2 , the embodiment of the present disclosure relates to a communication method, and the method includes:

[0136] Step S2101: The network device sends first information to the terminal.

[0137] In some embodiments, the first information is used to indicate the downlink transmit power of a specific beam and / or a specific beam group. The beam is a concept of physical implementation. From a standard perspective, the beam identifier can be replaced by a downlink reference signal ID, that is, the network device uses a beam formed by a specific coding method or beamforming method on the time-frequency resources corresponding to the downlink reference signal identifier to transmit a downlink reference signal. The beam identifier mentioned in this article can be understood as an identifier of a downlink reference signal. In some embodiments, the first information is used to indicate the downlink transmit power of a specific beam, which can be understood as the first information being used to indicate the downlink transmit power of a specific downlink reference signal. In some embodiments, the first information is used to indicate the downlink transmit power of a specific beam. In some embodiments, the first information is used to indicate the downlink transmit power of a specific beam group. In some embodiments, the first information is used to indicate the downlink transmit power of a specific beam and a specific beam group.

[0138] In some embodiments, the downlink transmit power indicates the power at which a network device transmits a downlink reference signal. In some embodiments, the downlink transmit power indicates the power at which a network device transmits a downlink reference signal via a beam. In some embodiments, the first information indicates the transmit power of a reference signal corresponding to a specific beam. In some embodiments, the first information indicates the transmit power of a reference signal corresponding to a specific beam group.

[0139] In some embodiments, the beam group includes at least two beams. Alternatively, it can also be understood that the beam group includes multiple beams. For example, a beam group includes 2 beams, a beam group includes 3 beams, or other situations, which are not limited in the embodiments of the present disclosure. In some embodiments, the beam group only includes an SSB (Synchronization Signal / PBCH Block) identifier. In some embodiments, the beam group includes both an SSB identifier and a CSI-RS identifier. In some embodiments, the beam group only includes a CSI-RS identifier. SSB stands for synchronization signal block, and the downlink reference signal mentioned in this article can be any one of the primary synchronization signal, secondary synchronization signal in the SSB, and DMRS signal in the PBCH.

[0140] In some embodiments, the first information includes any of the following:

[0141] (1) A specific beam identifier and the downlink transmit power corresponding to the specific beam identifier.

[0142] In some embodiments, the beam identifier is used to indicate a beam. In some embodiments, the beam identifier includes at least one of an SSB identifier or a CSI-RS identifier. In some embodiments, the beam indicated by the beam identifier is used to transmit at least one of an SSB or a CSI-RS.

[0143] In some embodiments, the downlink transmit power is an absolute value of power. That is, the beam identifier corresponds to the absolute value of the downlink transmit power. Alternatively, the absolute value can also be understood as a specific value, that is, the beam identifier corresponds to the specific value of the power.

[0144] In some embodiments, a beam identifier corresponds to a downlink transmit power. Alternatively, it can be understood that one beam identifier corresponds to one downlink transmit power. The downlink transmit power indicates the power at which a network device transmits a downlink reference signal. In other words, the downlink transmit power corresponding to a beam identifier indicates the power at which a network device transmits a downlink reference signal corresponding to the beam identifier.

[0145] For example, if the beam identifier is an SSB identifier and the downlink transmit power is represented by power, the corresponding relationship between the beam identifier and the downlink transmit power is expressed as: {SSB#1, power#1}, {SSB#2, power#2}…{SSB#n, power#n}. Alternatively, it can be expressed as {SSB#1, SSB#2, SSB#3, power#1}{SSB#4, SSB#5, SSB#6, power#2}.

[0146] For example, the beam identifier is a CSI-RS identifier, and the downlink transmit power is represented by power. The correspondence between the beam identifier and the downlink transmit power is expressed as: {CSI-RS#1, power#1}, {CSI-RS#2, power#2}…{CSI-RS#n, power#n}. Alternatively, it can be expressed as {CSI-RS#1, CSI-RS#2, CSI-RS#3, power#1}{CSI-RS#4, CSI-RS#5, CSI-RS#6, power#2}.

[0147] (2) A specific beam identifier, the downlink transmit power corresponding to any specific beam identifier, the difference between the downlink transmit power corresponding to other specific beam identifiers and the downlink transmit power of any specific beam identifier.

[0148] In some embodiments, the any beam identifier refers to a beam identifier among specific beam identifiers. If multiple specific beam identifiers are beam identifier 1, beam identifier 2, and beam identifier 3, the any beam identifier may be beam identifier 1, or the any beam identifier may be beam identifier 2, or the any beam identifier may be beam identifier 3.

[0149] In the disclosed embodiment, the first information indicates the downlink transmit power of a specific beam identifier, and then the other specific beam identifiers are indicated by the difference between the corresponding downlink transmit power and the downlink transmit power corresponding to any specific beam identifier. For example, if the first information indicates a downlink transmit power of 1 corresponding to beam identifier 1, and the difference corresponding to beam identifier 2 is difference 1, then the downlink transmit power corresponding to beam identifier 2 is the sum of downlink transmit power 1 and difference 1. If the difference corresponding to beam identifier 3 is difference 2, then the downlink transmit power corresponding to beam identifier 3 is the sum of downlink transmit power 1 and difference 2.

[0150] It should be noted that the difference between any two powers in the embodiment of the present disclosure may be a positive value or a negative value, and the embodiment of the present disclosure does not limit this.

[0151] It should be noted that in the embodiments of the present disclosure, there may be a situation where the difference between the downlink transmission power corresponding to a specific beam identifier and other specific beam identifiers is not indicated. In this case, the difference between the specific beam identifiers is 0.

[0152] In some embodiments, the beam identifier includes at least one of an SSB identifier or a CSI-RS identifier.

[0153] In some embodiments, the beam identifier is an SSB identifier, the downlink transmit power is represented by power, and the difference between the downlink transmit powers corresponding to the two beams is represented by offset. The first information may include {SSB#1, power#1}, {SSB#2, power offset#1}, {SSB#3, power offset#2}, where power offset#1 is the power difference between the power of SSB#2 and power#1 of SSB#1, and power offset#2 is the power difference between the power of SSB#3 and power#1 of SSB#1. It can be understood that the power of SSB#1 is power#1, the power of SSB#2 is power#1-power offset#1, and the power of SSB#3 is power#1-power offset#2.

[0154] In one embodiment, the beam identifier is an SSB identifier and a CSI-RS identifier, then the first information may include {SSB#1, power#1}, {SSB#2, power offset#1}, where power offset#1 is the power difference between the power of SSB#2 and the power#1 of SSB#1. It can be understood that the power of SSB#1 is power#1, the power of SSB#2 is power#1-power offset#1, and the first information is broadcasted via an SIB (System Information Blocks) message. Optionally, the first information also includes at least one power difference value, which is used to indicate the difference between the downlink transmit power of the SSB indicated by the SSB identifier and the downlink transmit power of the CSI-RS identifier. That is, in the embodiment of the present disclosure, the first information can also determine the downlink transmit power of the CSI-RS indicated by the CSI-RS identifier by indicating the difference between the downlink transmit power of the SSB indicated by the SSB identifier and the downlink transmit power of the CSI-RS indicated by the CSI-RS identifier. For example, the network device sends the first information to the UE through a UE-dedicated RRC (Radio Resource Control) message. At this time, the first information includes the CSI-RS ID and the power difference between the CSI-RS and the SSB power, power offset#2. Assume that the downlink reference signal corresponding to the uplink power control of the UE for the uplink channel PUSCH is CSI-RS#4, and CSI-RS#4 has a QCL relationship with SSB#2. Power offset#2 is the power difference between the power of CSI-RS#4 and SSB#2. It can be understood that the power of CSI-RS#4 is power#1-power offset#1-power offset#2.

[0155] (3) Multiple downlink transmission powers, where the multiple downlink transmission powers have a one-to-one correspondence with a specific beam or a specific beam group.

[0156] In the embodiment of the present disclosure, the first information includes multiple downlink transmission powers, and there is a one-to-one correspondence between each downlink transmission power and a specific beam or a specific beam group.

[0157] In some embodiments, the correspondence between the downlink transmit power and the specific beam or specific beam group is a default or specified by the communication protocol. Optionally, the downlink transmit power and the specific beam or specific beam group are sequentially associated from small to large. Alternatively, the downlink transmit power and the specific beam or specific beam group are sequentially associated from large to small.

[0158] For example, the downlink transmit power is expressed as power. Then the downlink transmit power is expressed as: {power#1},{power#2}…{power#n}, where power#1 corresponds to SSB#1, power#2 corresponds to SSB#2, and power#3 corresponds to SSB#3.

[0159] For another example, the downlink transmit power is represented by power. The downlink transmit power is represented as: {power#1}, {power#2}…{power#n}, where power#1 corresponds to specific beam group #10, power#2 corresponds to specific beam group #11, and power#3 corresponds to specific beam group #13. Specific beam group #10 includes SSB#1, SSB#2, and SSB#3; specific beam group #11 includes SSB#4, SSB#5, and SSB#6; and specific beam group #12 includes SSB#7, SSB#8, and SSB#9.

[0160] For example, if the beam identifier is a CSI-RS identifier and the downlink transmit power is represented by power, the corresponding relationship between the beam identifier and the downlink transmit power is expressed as: {power#5}, {power#6}, where power#5 corresponds to CSI-RS#5 and power#6 corresponds to CSI-RS#6.

[0161] (4) A downlink transmission power and a difference therebetween with the downlink transmission power, a downlink transmission power and a difference therebetween with the downlink transmission power are in a one-to-one correspondence with a specific beam or a specific beam group, respectively.

[0162] In some embodiments, the first information includes a downlink transmit power and the difference between the downlink transmit power, and the downlink transmit power and the difference between the downlink transmit power correspond to a specific beam or a specific beam group, ensuring that the terminal can determine the accuracy of the transmit power of the beam corresponding to the measured downlink reference signal.

[0163] For example, the beam identifier is an SSB identifier, and the downlink transmit power is represented by power. The predefined correspondence between beams and powers is one-to-one, and the power is mapped one-to-one in ascending order of the SSB ID. The first information includes {power#1, power#2…power#n}. It can be understood that based on the first information, the UE can know that the power of SSB#1 is power#1, the power of SSB#2 is power#2, and the power of SSB#n is power#n.

[0164] For another example, the beam identifier is an SSB identifier, the downlink transmit power is represented by power, and the difference between the downlink transmit power and the power offset is represented by power offset. The correspondence between the predefined beam and the power difference is one-to-one, and the power corresponds one-to-one in ascending order of the SSB ID. The first information includes {power offset#1, power offset#2…power offset#n}. It can be understood that the UE can know from the first information that the power of SSB#1 is power#1+power offset#1, the power of SSB#2 is power#1+power offset#2, and the power of SSB#n is power#1++power offset#n. Among them, power#1 refers to the initial SSB value. Optionally, the power#1 is configured by the first information.

[0165] In one embodiment, the beam identifier is an SSB identifier and a CSI-RS identifier, then the first information may include {power#1}, {power offset#1}, wherein power#1 is the downlink transmit power of SSB#1, and power offset#1 is the power difference between the power of SSB#2 and the power#1 of SSB#1. It can be understood that the power of SSB#1 is power#1, the power of SSB#2 is power#1-power offset#1, and the first information is sent through SIB message broadcast. Optionally, the first information also includes at least one power difference value, and the power difference value is used to indicate the difference between the downlink transmit power of the SSB indicated by the SSB identifier and the downlink transmit power of the CSI-RS identifier. That is, in the embodiment of the present disclosure, the first information can also determine the downlink transmit power of the CSI-RS indicated by the CSI-RS identifier by indicating the difference between the downlink transmit power of the SSB indicated by the SSB identifier and the downlink transmit power of the CSI-RS indicated by the CSI-RS identifier. For example, the network device sends the first information to the UE through a UE-dedicated RRC message. In this case, the first information includes the CSI-RS ID and the power difference between the CSI-RS and the SSB power, power offset #2. Assume that the downlink reference signal corresponding to the UE's uplink power control for the uplink channel PUSCH is CSI-RS #4, and CSI-RS #4 has a QCL relationship with SSB #2. Power offset #2 is the power difference between the power of CSI-RS #4 and SSB #2. It can be understood that the power of CSI-RS #4 is power #1-power offset #1-power offset #2.

[0166] (5) A specific beam group identifier and the downlink transmit power corresponding to the specific beam group identifier.

[0167] In some embodiments, a specific beam group identifier further corresponds to multiple beam identifiers. Alternatively, it can also be understood that the beam group corresponding to the specific beam group identifier includes multiple beams, and each beam in the multiple beams is indicated by a beam identifier.

[0168] In some embodiments, the beam identifier includes at least one of an SSB identifier or a CSI-RS identifier.

[0169] In some embodiments, the beam identifier is an SSB identifier. The beam group identifier is represented by group, and the downlink transmit power is represented by power. The downlink transmit power is then represented as: {group#1, power#1}, {group#2, power#2}…{group#n, power#n}, where power#1 corresponds to specific beam group #1, power#2 corresponds to specific beam group #2, and power#3 corresponds to specific beam group #3. Specific beam group #1 includes SSB#1, SSB#2, and SSB#3; specific beam group #2 includes SSB#4, SSB#5, and SSB#6; and specific beam group #3 includes SSB#7, SSB#8, and SSB#9.

[0170] In some embodiments, the beam identifier is a CSI-RS identifier. The beam group identifier is represented by group, and the downlink transmit power is represented by power. The downlink transmit power is then represented as: {group#1, power#1}, {group#2, power#2}…{group#n, power#n}, where power#1 corresponds to specific beam group #1, power#2 corresponds to specific beam group #2, and power#3 corresponds to specific beam group #3. Specific beam group #1 includes CSI-RS#1, CSI-RS#2, and CSI-RS#3; specific beam group #2 includes CSI-RS#4, CSI-RS#5, and CSI-RS#6; and specific beam group #3 includes CSI-RS#7, CSI-RS#8, and CSI-RS#9.

[0171] (6) Specific beam group identifier, the downlink transmit power corresponding to any specific beam group identifier, and the difference between the downlink transmit power corresponding to other specific beam group identifiers.

[0172] Optionally, the difference between the downlink transmit power corresponding to other specific beam group identifiers refers to the difference between the downlink transmit power corresponding to other specific beam group identifiers and the downlink transmit power corresponding to any specific beam group identifier.

[0173] In some embodiments, the any specific beam group identifier refers to a beam group identifier among the specific beam group identifiers. If the multiple specific beam group identifiers are beam group identifier 1, beam group identifier 2, and beam group identifier 3, the any beam group identifier may be beam group identifier 1, or the any beam identifier may be beam group identifier 2, or the any beam identifier may be beam group identifier 3.

[0174] In the disclosed embodiment, the first information indicates the downlink transmit power of a specific beam group identifier, and then the other specific beam group identifiers are indicated by the difference between the corresponding downlink transmit power and the downlink transmit power corresponding to any specific beam group identifier. For example, if the first information indicates a downlink transmit power of 1 corresponding to beam group identifier 1, and the difference corresponding to beam group identifier 2 is difference 1, then the downlink transmit power corresponding to beam group identifier 2 is the sum of downlink transmit power 1 and difference 1. If the difference corresponding to beam group identifier 3 is difference 2, then the downlink transmit power corresponding to beam group identifier 3 is the sum of downlink transmit power 1 and difference 2.

[0175] It should be noted that the difference between any two powers in the embodiment of the present disclosure may be a positive value or a negative value, and the embodiment of the present disclosure does not limit this.

[0176] It should be noted that in the embodiments of the present disclosure, there may be a situation where the difference between the downlink transmission power corresponding to a specific beam group identifier and other specific beam group identifiers is not indicated. In this case, the difference between the specific beam group identifiers is 0.

[0177] In some embodiments, the beam identifier includes at least one of an SSB identifier or a CSI-RS identifier. That is, the beam group identifier includes at least one of an SSB group identifier or a CSI-RS group identifier.

[0178] In some embodiments, the beam group identifier is an SSB group identifier, the downlink transmit power is represented by power, and the difference between the downlink transmit powers corresponding to the two beam groups is represented by offset. The first information may include {SSB group#1, power#1}, {SSB group#2, power offset#1}, {SSB group#3, power offset#2}, where power offset#1 is the power difference between the power of SSB group#2 and the power#1 of SSB group#1, and power offset#2 is the power difference between the power of SSB group#3 and the power#1 of SSB group#1. It can be understood that the power of SSB group#1 is power#1, the power of SSB group#2 is power#1-power offset#1, and the power of SSB group#3 is power#1-power offset#2. Each SSB group in SSB group#1, SSB group#2, and SSB group#3 includes multiple SSBs.

[0179] In one embodiment, the beam identifier is an SSB identifier and a CSI-RS identifier, then the first information may include {SSB group#1, power#1}, {SSB group#2, power offset#1}, where power offset#1 is the power difference between the power of SSB group#2 and the power#1 of SSB group#1. It can be understood that the power of SSB group#1 is power#1, the power of SSB group#2 is power#1-power offset#1, and the first information is sent through SIB message broadcast. Optionally, the first information also includes at least one power difference value, which is used to indicate the difference between the downlink transmit power of the SSB group indicated by the SSB group identifier and the downlink transmit power of the CSI-RS group identifier. That is, in the embodiment of the present disclosure, the first information can also determine the downlink transmit power of the CSI-RS group indicated by the CSI-RS group identifier by indicating the difference between the downlink transmit power of the SSB group indicated by the SSB group identifier and the downlink transmit power of the CSI-RS group indicated by the CSI-RS group identifier. For example, the network device sends first information to the UE via a UE-dedicated RRC message. In this case, the first information includes the CSI-RS group ID and the power difference (power offset #2) between the CSI-RS group and the SSB group. Assume that the downlink reference signal corresponding to the UE's uplink power control for the uplink channel PUSCH is CSI-RS group #4, and that CSI-RS group #4 and SSB group #2 have a QCL relationship. Power offset #2 is the power difference between the power of CSI-RS group #4 and SSB group #2. It can be understood that the power of CSI-RS group #4 is power #1 - power offset #1 - power offset #2.

[0180] It should be noted that the above embodiments are all about the content included in the first information. However, there are different situations for the beam identifier and power difference. The beam identifier and power difference included in the first information are described below.

[0181] In some embodiments, the beam identifier included in the first information is an SSB identifier, and the first information also includes at least one power difference value, which is used to indicate the difference between the downlink transmit power of the SSB indicated by the SSB identifier and the downlink transmit power of the CSI-RS identifier.

[0182] In an embodiment of the present disclosure, the first information includes an SSB identifier, and the first information may also indicate the downlink transmit power of the CSI-RS identifier. The downlink transmit power of the CSI-RS identifier is determined by the power difference and the downlink transmit power of the SSB indicated by the SSB identifier.

[0183] Optionally, the first information includes an SSB identifier and the downlink transmit power corresponding to the SSB identifier, and also includes at least one power difference, so as to indicate the downlink transmit power of the CSI-RS identifier through the power difference.

[0184] In some embodiments, there are multiple power difference values ​​and the SSB identifier and the power difference value have a one-to-one correspondence. In the embodiments of the present disclosure, each power difference value has a one-to-one correspondence with an SSB, that is, one SSB identifier corresponds to one power difference value, and each power difference value indicates the downlink transmit power of one CSI-RS identifier, that is, one SSB identifier corresponds to one CSI-RS.

[0185] Optionally, the first information includes multiple SSB identifiers, and each SSB identifier corresponds to a downlink transmit power. In addition, each SSB identifier also corresponds to a power difference value. That is, for each power difference value, the downlink transmit power of the CSI-RS identifier can be determined according to the downlink transmit power corresponding to the corresponding SSB identifier. Optionally, the number of SSB identifiers is the same as the number of power differences.

[0186] In some embodiments, there are multiple power difference values ​​and there is a one-to-one correspondence between the CSI-RS identifier and the power difference value. In the embodiment of the present disclosure, the power difference value refers to the difference between the downlink transmit power corresponding to the SSB identifier and the downlink transmit power corresponding to the CSI-RS identifier.

[0187] Optionally, the first information includes an SSB identifier and the downlink transmit power corresponding to the SSB identifier, and also includes multiple power difference values, each power difference value is the difference between the downlink transmit powers corresponding to the SSB identifier, and each power difference value corresponds one-to-one to the CSI-RS, so the downlink transmit power corresponding to a CSI-RS identifier can be determined based on each power difference value.

[0188] In some embodiments, the power difference is one, and the difference between the downlink transmit power of multiple SSBs and the downlink transmit power of multiple CSI-RSs is the same. In the disclosed embodiments, the SSB identifier and the CSI-RS identifier are in a one-to-one correspondence. That is, one SSB identifier corresponds to one CSI-RS identifier.

[0189] Step S2102: The terminal receives first information sent by the network device.

[0190] In some embodiments, the network device sends the first information. In some embodiments, the terminal receives the first information.

[0191] In an embodiment of the present disclosure, the terminal receives the first information sent by the network device, and can determine the downlink transmission power corresponding to each beam identifier indicated by the first information, or the downlink transmission power corresponding to each beam group.

[0192] In some embodiments, the first information is SIB information, that is, the downlink transmission power of the beam and / or beam group indicated by the network device is indicated through SIB information.

[0193] In one embodiment, the downlink transmission power of the downlink reference signal indicated by the SSB identifier is sent through SIB information. When the network device configures the downlink reference signal for uplink power control for the terminal to be CSI-RS, the network device indicates the power difference between the downlink power of the CSI-RS and the SSB with which it is associated with QCL through UE-dedicated RRC signaling.

[0194] In one embodiment, the first information may be carried by different signaling in different situations, and the content of the first information carried by different signaling may be different. For example, the base station broadcasts the first information through an SIB message, and the first information includes multiple SSB identifiers and multiple powers. The SSB identifier and the power have a one-to-one correspondence, {SSB#1, power1; SSB#2, power2; SSB#3, power1; SSB#4, power2}. In the UE idle / inactive state, the UE measures the RSRP of different SSB identifiers and selects the PRACH configuration corresponding to the SSB identifier with a high RSRP to send PRACH. The UE determines the downlink transmission loss based on the transmit power corresponding to the selected SSB identifier, and determines the uplink transmit power of the PRACH. When the UE enters the connected state, the base station carries the first information and other information through UE-dedicated RRC messages, such as serving cell config information. The other information includes:

[0195] The downlink reference signal ID corresponding to the uplink power control of PUSCH is SSB#1

[0196] The downlink reference signal ID corresponding to the uplink power control of PUCCH is SSB#1

[0197] The downlink reference signal ID corresponding to the uplink power control of SRS is CSI-RS#1

[0198] Among them, CSI-RS#1 and SSB#1 have a QCL relationship.

[0199] The first information includes:

[0200] The power difference between CSI-RS#1 and SSB#1 is offset#1.

[0201] The terminal determines that the downlink reference signal transmit power used for the uplink power control of PUSCH is power#1, the downlink reference signal transmit power used for the uplink power control of PUCCH is power#1, and the downlink reference signal transmit power used for the uplink power control of SRS is power#1-offset#1. In one embodiment, the information carrying the downlink transmit power is modified through other signaling, such as UE-dedicated RRC or group-common dynamic signaling. Its parameter value is modified.

[0202] Step S2103: The terminal determines the path loss for uplink power control based on the downlink transmit power.

[0203] In some embodiments, the path loss refers to a loss incurred when the reference signal is transmitted between the network device and the terminal. In some embodiments, the path loss refers to a loss incurred when the reference signal is transmitted between the network device and the terminal due to channel effects or radiation effects.

[0204] In some embodiments, the uplink power control path loss is determined based on the difference between the downlink transmit power and the terminal's downlink receive power, where the downlink receive power indicates the power at which the terminal receives a downlink reference signal. Alternatively, the uplink power control path loss is the difference between the downlink transmit power and the downlink receive power obtained by the terminal receiving the reference signal. In some embodiments, if the uplink power control path loss is 0, communication between the network device and the terminal is unaffected and signal loss is not experienced.

[0205] In the embodiments of the present disclosure, the downlink transmit power indicated by the terminal is different, and the method of determining the path loss of uplink power control is also different. The following describes how to determine the path loss.

[0206] In some embodiments, if the beam identifier included in the first information is an SSB identifier, and the SSB identifier corresponds to a downlink transmit power, the path loss for determining the uplink power is the difference between the downlink transmit power corresponding to the SSB identifier and the downlink receive power of the SSB indicated by the SSB identifier received by the terminal. For example, the downlink reference signal is SSB, and the path loss is PL b,f,c (q d), the downlink transmit power corresponding to the SSB identifier is referenceSignalPower(SSB index), and the downlink receive power of the SSB indicated by the SSB identifier received by the terminal is higher layer filtered RSRP, then the terminal calculates PL according to the power corresponding to the determined SSB index b,f,c (q d ), PL b,f,c (q d )=referenceSignalPower(SSB index)–higher layer filtered RSRP.

[0207] In some embodiments, if the downlink reference signal is CSI-RS, the uplink power path loss is the difference between the downlink transmit power corresponding to the CSI-RS identifier and the downlink receive power of the CSI-RS indicated by the CSI-RS identifier received by the terminal. For example, if the downlink reference signal is CSI-RS, the path loss is PL b,f,c (q d ), the downlink transmit power corresponding to the CSI-RS identifier is referenceSignalPower, and the downlink receive power of the CSI-RS indicated by the CSI-RS identifier received by the terminal is higher layer filtered RSRP, then the terminal calculates PL according to the power corresponding to the determined CSI-RS index b,f,c (q d ), PL b,f,c (q d )=referenceSignalPower–higher layer filtered RSRP.

[0208] Optionally, if the network device indicates a uniform / unique power difference powerControlOffsetSS between the CSI-RS and the SSB, the terminal determines the referenceSignalPower of the CSI-RS according to the SSB index corresponding to the CSI-RS QCL typeD and the powerControlOffsetSS.

[0209] Optionally, if the network device indicates multiple power differences powerControlOffsetSS between CSI-RS and SS, that is, the powerControlOffsetSS between CSI-RS and SSB is also beam or beam group specific, then the terminal determines the referenceSignalPower of CSI-RS according to the SSB index corresponding to the CSI-RS QCL typeD and the corresponding powerControlOffsetSS.

[0210] Optionally, if the network device does not indicate the power difference between the CSI-RS and the SS, the default power difference is 0.

[0211] Step S2104: The terminal determines the transmit power of the uplink signal / uplink channel based on the uplink power control path loss.

[0212] In some embodiments, the terminal determines the path loss for uplink power control based on the downlink transmit power, and further determines the transmit power of the uplink signal / uplink channel transmitted by the terminal based on the determined path loss.

[0284] FIG6 is a flow chart of a communication method according to an embodiment of the present disclosure. As shown in FIG6 , the embodiment of the present disclosure relates to a communication method, and the method includes:

[0285] Step S6101: The terminal receives the downlink transmission power broadcast by the network device.

[0286] In some embodiments, the downlink transmit power is beam-specific or beam group-specific.

[0287] In some embodiments, when the terminal calculates the transmission loss for uplink power control, referenceSignalPower in 〖PL〗_(b,f,c)(q_d)=referenceSignalPower–higher layer filtered RSRP depends on whether it is beam-specific or beam group-specific.

[0288] In some embodiments, the beam-specific or beam group-specific power information is sent in the SIB.

[0289] In some embodiments, the specific content format is sent in the SIB:

[0290] (1) beam index, multiple power absolute values

[0291] (2) Beam index, a form of power absolute value + power difference

[0292] (3) Multiple power values

[0293] (4) A form of power absolute value + power difference

[0294] In some embodiments, the SSB index and the corresponding power are indicated in the SIB, such as {SSB#1, power#1}, {SSB#2, power#2}…{SSB#n, power#n} or {SSB#1, SSB#2, SSB#3, power#1}{SSB#4, SSB#5, SSB#6, power#2}

[0295] In some embodiments, the SIB indicates {SSB#1, power#1}, {SSB#2, power offset#1}, {SSB#3, power offset#2}, where power offset#1 and power offset#2 are the power differences between the power of SSB#2 and SSB#3 and power#1 of SSB#1. Or {SSB#1, SSB#2, SSB#3, power#1} {SSB#4, SSB#5, SSB#6, power offset}

[0296] In some embodiments, the SIB only indicates power, and power and SSB index are in a one-to-one correspondence.

[0297] In some embodiments, the terminal determines the base station downlink transmit power according to the power corresponding to the determined downlink reference signal and calculates the coupling loss, which is calculated as 〖PL〗_(b,f,c)(q_d)=referenceSignalPower–higher layer filtered RSRP

[0298] In some embodiments, if the downlink reference signal is SSB, the terminal calculates 〖PL〗_(b,f,c)(q_d) according to the power corresponding to the determined SSB index, 〖PL〗_(b,f,c)(q_d)=referenceSignalPower(SSB index)–higher layer filtered RSRP.

[0299] In some embodiments, if the downlink reference signal is a non-SSB, such as CSI-RS, and if the base station indicates a uniform / unique power difference powerControlOffsetSS between the CSI-RS and the SS, the UE determines the referenceSignalPower of the CSI-RS based on the SSB index corresponding to the CSI-RS QCL typeD and the offset.

[0300] If the base station indicates multiple power differences between CSI-RS and SS powerControlOffsetSS, that is, the offset between CSI-RS and SS is also beam or beam group specific, then the UE determines the referenceSignalPower of the CSI-RS based on the SSB index corresponding to the CSI-RS QCL typeD and the corresponding offset

[0301] If the base station does not indicate the power difference between CSI-RS and SS, the default power difference is 0.

[0302] In some embodiments, during the initial access process, the UE calculates 〖PL〗_(b,f,c)(q_d) based on the SSB index x selected for access and the power corresponding to the SSB index x indicated in the SIB, where qd represents the corresponding SSB index.

[0303] In some embodiments, when the UE calculates 〖PL〗_(b,f,c)(q_d), qd is the CSI-RS, and the base station indicates the unique power difference powerControlOffsetSS between the CSI-RS and the SS, then the UE determines the referenceSignalPower of the CSI-RS based on the SSB index corresponding to the CSI-RS QCL typeD and the offset.

[0304] In the embodiments of the present disclosure, some or all of the steps and their optional implementations may be arbitrarily combined with some or all of the steps in other embodiments, or may be arbitrarily combined with the optional implementations of other embodiments.
