Description

Technical Field

[0001] The embodiments of the present application relate to the field of communication technology, and specifically to an information processing method and terminal equipment. Background Art

[0002] In the New Radio (NR) system, the terminal device can use multiple beams for uplink transmission. When the terminal device is close to the human body, the transmit power or effective isotropic radiated power (EI RP) may exceed the specified safety value. At this time, in order to ensure the safety of the human body, the terminal device can perform power backoff processing for one or more transmit beams, that is, reduce the transmit power of the terminal.

[0003] Since the transmit beam has a certain directionality, the transmit beam and the human body may have different positional relationships. If the transmit power or EI RP of the terminal device exceeds the specified safety value, the terminal device can determine the power backoff value of each transmit beam based on the positional relationship between each transmit beam and the human body. For example, if a transmit beam is aimed at the human body, power backoff processing is required. If a transmit beam is not aimed at the human body, power backoff processing is not required or the power backoff value in the power backoff processing is reduced.

[0004] However, since the power backoff value of each transmit beam may be different, it may affect the uplink transmission performance of the terminal device. Therefore, it is urgent to provide a method to achieve reliable uplink transmission of multiple transmit beams. Summary of the invention

[0024] The following will describe the technical solutions in the embodiments of the present application in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments.

[0027] The communication system 100 also includes at least one terminal device 120 located within the coverage of the network device 110. As used herein, "terminal device" includes but is not limited to a connection via a wired line, such as via a Public Switched Telephone Networks (PSTN), a Digital Subscriber Line (DSL), a digital cable, a direct cable connection; and / or another data connection / network; and / or via a wireless interface, such as, for a cellular network, a Wireless Local Area Network (WLAN), a digital television network such as a DVB-H network, a satellite network, an AM-FM broadcast transmitter; and / or a device of another terminal device configured to receive / send communication signals; and / or an Internet of Things (IoT) device. A terminal device configured to communicate via a wireless interface may be referred to as a "wireless communication terminal device", a "wireless terminal device" or a "mobile terminal device". Examples of mobile terminal devices include, but are not limited to, satellite or cellular telephones; Personal Communications System (PCS) terminal devices that may combine cellular radiotelephones with data processing, fax, and data communications capabilities; PDAs that may include radiotelephones, pagers, Internet / Intranet access, Web browsers, notepads, calendars, and / or Global Positioning System (GPS) receivers; and conventional laptop and / or palmtop receivers or other electronic devices that include radiotelephone transceivers.

[0028] Optionally, terminal devices 120 may perform device to device (D2D) communication.

[0029] Optionally, the 5G system or 5G network may also be referred to as a New Radio (NR) system or NR network.

[0030] Figure 1 One network device and two terminal devices are shown exemplarily. Optionally, the communication system 100 may include multiple network devices and each network device may include another number of terminal devices within its coverage area, which is not limited in the embodiments of the present application.

[0031] Optionally, the communication system 100 may also include other network entities such as a network controller and a mobility management entity, which is not limited in the embodiments of the present application.

[0032] It should be understood that the device with communication function in the network / system in the embodiment of the present application can be referred to as a communication device. Figure 1 Taking the communication system 100 shown as an example, the communication equipment may include a network device 110 and a terminal device 120 with communication functions. The network device 110 and the terminal device 120 may be the specific devices described above and will not be repeated here. The communication equipment may also include other devices in the communication system 100, such as a network controller, a mobile management entity and other network entities, which is not limited in the embodiments of the present application.

[0033] It should be understood that the terms "system" and "network" are often used interchangeably in this article. The term "and / or" in this article is only a description of the association relationship of associated objects, indicating that three relationships can exist. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " in this article generally indicates that the associated objects before and after are in an "or" relationship.

[0034] According to the regulations of various countries / regions / industry organizations, for the sake of human safety, the transmit power of terminal equipment needs to be controlled within the prescribed safety range. Therefore, a safety value of transmit power or effective isotropic radiated power (EI RP) is set to limit the transmit power of terminal equipment.

[0035] When the terminal device is close to the human body, the transmission power or effective isotropic radiated power (EIRP) may exceed the specified safety value. Since the transmission beam has a certain directionality, the transmission beam and the human body will have different positional relationships. If the transmission power or EIRP of the terminal device exceeds the specified safety value, the terminal device can determine the power backoff value of each transmission beam based on the positional relationship between each transmission beam and the human body. For example, if a transmission beam is aimed at the human body, power backoff processing is required. If a transmission beam is not aimed at the human body, power backoff processing is not required or the power backoff value in the power backoff processing is reduced.

[0036] Then, if it is necessary to adopt corresponding power backoff processing according to the above description based on the judgment standard of whether different transmit beams or different transmit beam groups are aimed at the human body, the existing beam management mechanism may cause performance degradation. Some examples are as follows:

[0037] For example, if the network device configures a non-periodic channel sounding reference signal (SRS) for the terminal device, and selects a certain transmission beam of the terminal device based on the non-periodic SRS as the uplink transmission beam, and notifies the terminal device to use the selected transmission beam for uplink transmission. If the terminal device moves or rotates, and the current working transmission beam is aimed at the human body, power fallback processing is required, which will cause the actual transmission power of the current working transmission beam to be low, so that there is another transmission beam with better actual transmission effect, then the current working transmission beam is not an optimal choice. At this time, the network device may not be able to learn of this situation in time, and thus reselect the uplink transmission beam of the network.

[0038] Or, for another example, based on the optimal or relatively optimal downlink transmission beam, the transmission beam of the terminal device is determined as the uplink transmission beam. If this transmission beam is aimed at the human body and power fallback is required, the actual transmission power of the currently working transmission beam will be low, so there is a situation where another transmission beam actually has a better transmission effect, and the currently working transmission beam is not an optimal choice. At this time, the network device may not be able to learn of this situation in time, so as to reselect the uplink transmission beam of the network.

[0039] In view of the above-mentioned problems, the main idea of ​​the technical solution provided by this application is that the terminal device reports information to assist or suggest the network device to perform the corresponding transmission beam management process, such as transmission beam selection, transmission beam indication, etc. In this way, the network device can quickly obtain information and perform the corresponding process or indication in a timely manner, thereby realizing reliable uplink transmission of multiple transmission beams.

[0040] Figure 2 It is a schematic diagram of an information processing method 200 provided in an embodiment of the present application.

[0041] 210. The terminal device sends power backoff information corresponding to at least one transmit beam or reference signal resource to the network device.

[0042] The term beam mentioned in this application is a term used in daily discussions and manuscripts. In actual communication protocols, the term beam is often invisible and can be identified or indicated by the reference signal resources it carries or the corresponding reference signal resources. For the convenience of expression, reference signal resources are sometimes abbreviated as signal resources.

[0043] For example, different synchronization signal blocks (SSB), namely SS / PBCH blocks, are transmitted on different beams, and the terminal device can identify different downlink transmission beams through different SS / PBCH blocks.

[0044] Among them, the primary synchronization signal (Primary Synchronization Signa l, PSS), the secondary synchronization signal (Secondary Synchronization Signa l, SSS) and the physical broadcast channel (Phys ica l Broadcast Channel, PBCH) together constitute a synchronization signal block (Synchronization Signa l Block, SSB), namely SS / PBCH block.

[0045] Or, for another example, signals corresponding to different channel state information reference signals (CSI-RS) resources are transmitted on different beams, and the terminal device can identify different downlink transmission beams through CSI-RS / CSI-RS resources.

[0046] Or, for another example, signals corresponding to different SRS resources are transmitted on different beams, and the network device can identify different uplink transmission beams through SRS / SRS resources.

[0047] Or, for another example, when the terminal device has beam correspondence (i.e., if receiving beam X is a better / best choice for receiving a downlink signal, the terminal device infers that its corresponding transmitting beam Y is a better / best uplink transmitting beam based on receiving beam X), if the network device indicates that the corresponding downlink signal of a certain downlink transmitting beam is A, the terminal device can infer its corresponding transmitting beam C based on the receiving beam B corresponding to the received downlink signal A. In this case, in addition to directly indicating the uplink transmitting beam C of the terminal device, the network device can also indirectly indicate the uplink transmitting beam C by indicating the downlink signal A.

[0048] Therefore, the transmitting beam of the terminal device disclosed in the present application may correspond to at least one of SRS / SRS resources, synchronization signal block (Synchronization Signa l Block, SSB) and channel state information reference signal (Channel StateI nformat ion-Reference Signa l, CSI-RS) / CSI-RS resources, and this embodiment does not specifically limit this.

[0049] Therefore, the network device may specifically indicate the corresponding transmit beam by indicating at least one of the following corresponding signal identifiers:

[0050] SRS resource indicator (SRS resource indicator, SRI);

[0051] Synchronization signal block identifier (SSB index); and

[0052] CSI-RS resource identifier (CSI-RS resource identifier);

[0053] Optionally, some signaling, in addition to the SRI, may further include indication information corresponding to an uplink bandwidth part (Bandwidth Part, BWP) identifier (BWP ID) where the SRS resource is located.

[0054] Accordingly, the reference signal resource may include but is not limited to at least one of SRS / SRS resources, synchronization signal blocks and CSI-RS / CSI-RS resources, which is not particularly limited in this embodiment.

[0055] In the present application, for the scenario where the terminal device uses multiple transmission beams, the terminal device can determine whether the transmission beam needs to be power backoff processed according to the situation, for example, whether each transmission beam is close to the human body and other factors. If one or more transmission beams need to be power backoff processed, then the terminal device can determine the power backoff value of the power backoff processing corresponding to each transmission beam, and perform operations related to the transmission power of these transmission beams according to the power backoff value.

[0056] Optionally, in a possible implementation of this embodiment, in 210, the terminal device may send power backoff information corresponding to the at least one transmit beam or reference signal resource to the network device specifically according to relevant conditions.

[0057] In a specific implementation process, if the constraint condition of the power backoff value is met, the terminal device can send the power backoff information corresponding to the at least one transmit beam or reference signal resource to the network device. In this way, only when the constraint condition of the power backoff value is met, the terminal device will report the information, thereby effectively reducing the resource demand for the uplink channel and saving uplink resources. At the same time, it can also reduce the uplink interference in the system.

[0058] In this implementation process, the constraint condition of the power backoff value may include but is not limited to at least one of the following conditions:

[0059] There is a transmit beam or reference signal resource or a transmit beam group or reference signal resource group whose corresponding power backoff value is greater than or equal to the first threshold; and

[0060] There are two transmit beams or reference signal resources or two transmit beam groups or reference signal resource groups whose difference or ratio between power backoff values ​​is greater than or equal to a second threshold.

[0061] It should be noted that the so-called difference may refer to the difference between power backoff values ​​in the dB domain; the so-called ratio may refer to the ratio between linear power backoff values.

[0062] In addition, the difference refers to the absolute value.

[0063] The first threshold may be agreed upon by a protocol, or may be determined by the terminal device, or may be indicated by the network device, which is not particularly limited in this embodiment.

[0064] If the first threshold is indicated by a network device, the terminal device may specifically receive at least one of the following messages sent by the network device to indicate the first threshold:

[0065] System broadcast messages;

[0066] Radio Resource Control (RRC) signaling;

[0067] Media Access Control (MAC) Control Element (CE) signaling; and

[0068] Downlink control information (Downlink Control Information, DCI).

[0069] The second threshold may be agreed upon by a protocol, or may be determined by the terminal device, or may be indicated by the network device, which is not particularly limited in this embodiment.

[0070] If the second threshold is indicated by the network device, the terminal device may specifically receive at least one of the following messages sent by the network device to indicate the second threshold:

[0071] System broadcast messages;

[0072] RRC signaling;

[0073] MAC CE signaling; and

[0074] DCI.

[0075] In another specific implementation process, if the reporting conditions of the power situation report are met, the terminal device can send power backoff information corresponding to the at least one transmit beam or reference signal resource to the network device.

[0076] The power situation report may include but is not limited to a power headroom report (Power Headroom Report, PHR), which is not particularly limited in this embodiment.

[0077] In another specific implementation process, the terminal device can specifically send the power backoff information corresponding to the at least one transmit beam or reference signal resource to the network device based on the configuration information.

[0078] For example, the configuration information may be periodically reported configuration information, semi-persistently reported configuration information, or aperiodically reported configuration information.

[0079] The configuration information may be agreed upon by a protocol, or may be determined by the terminal device, or may be indicated by the network device, which is not particularly limited in this embodiment.

[0080] In this implementation, the power backoff information corresponding to the at least one transmit beam or reference signal resource may include, but is not limited to, at least one of the following information:

[0081] Reporting instructions;

[0082] Power fallback value information; and

[0083] Send beam or reference signal resource indication information.

[0084] The power backoff value information may include but is not limited to at least one of the following information:

[0085] Power backoff values ​​corresponding to one or more transmit beams or reference signal resources;

[0086] Power backoff values ​​corresponding to one or more transmit beam groups or reference signal resource groups;

[0087] a difference or ratio between power backoff values ​​corresponding to one or more groups of two transmit beams or reference signal resources; and

[0088] The difference or ratio between the power backoff values ​​corresponding to one or more groups of two transmit beam groups or reference signal resource groups.

[0089] The transmit beam or reference signal resource indication information may include, but is not limited to, at least one of the following information:

[0090] a transmit beam indication of one or more transmit beams or a reference signal resource indication of a reference signal resource;

[0091] a transmit beam group indicator of one or more transmit beam groups or a reference signal resource group indicator of a reference signal resource group;

[0092] a transmit beam indication of one or more groups of two transmit beams or a reference signal resource indication of a reference signal resource; and

[0093] The transmit beam group indication of one or more groups of two transmit beam groups or the reference signal resource group of the reference signal resource group refers to: In this implementation, the one transmit beam or the reference signal resource may specifically include but is not limited to the following:

[0094] The currently operating transmit beam or reference signal resource; or

[0095] The transmit beam or reference signal resource that was most recently active before the specified time, for example, before the interval P, or before P time slots (s lot), or before P symbols (symbo l), etc.; or

[0096] Specifying any one of a group of transmit beams or reference signal resources, wherein the specifying of a group of transmit beams or reference signal resources may be agreed upon by a protocol, or may be determined by the terminal device, or may be indicated by the network device; or

[0097] Any one of all transmit beams or reference signal resources used for uplink transmission of the terminal device.

[0098] The transmission beam or reference signal resource indication refers to identification information used to indicate the transmission beam or reference signal resource, for example, identification information of a certain signal or signal resource.

[0099] The transmission beam group or reference signal resource group indication refers to identification information used to indicate the transmission beam group or reference signal resource group, for example, identification information of a certain signal group or signal resource group.

[0100] In this implementation, the one transmit beam group or reference signal resource group may specifically include but is not limited to the following situations:

[0101] the transmit beam group to which the currently operating transmit beam belongs or the reference signal resource group to which the reference signal resource belongs; or

[0102] A transmit beam group to which a transmit beam that was most recently active before a specified time belongs or a reference signal resource group to which a reference signal resource belongs, for example, before an interval of P, or before P time slots (s lot), or before P symbols (symbo l), etc.; or

[0103] Any one transmission beam group or reference signal resource group among all transmission beams or reference signal resources used for uplink transmission of the terminal device.

[0104] In this implementation, the two transmit beams or reference signal resources may specifically include but are not limited to the following situations:

[0105] Any two transmit beams or reference signal resources among all transmit beams or reference signal resources used for uplink transmission of the terminal device; or

[0106] any one of the currently working transmit beam or reference signal resource and all transmit beams or reference signal resources used for uplink transmission of the terminal device except the currently working transmit beam or reference signal resource; or

[0107] The transmit beam or reference signal resource that most recently worked before a specified time and any transmit beam or reference signal resource among all transmit beams or reference signal resources used for uplink transmission of the terminal device except the transmit beam or reference signal resource that most recently worked before the specified time, for example, before an interval of P, or for another example, before P time slots (s lot), or for another example, before P symbols (symbo l), etc.

[0108] In this implementation, the two transmit beam groups or reference signal resource groups may specifically include but are not limited to the following situations:

[0109] Any two transmit beam groups or reference signal resource groups among all transmit beams or reference signal resources used for uplink transmission of the terminal device; or

[0110] any one of the transmit beam group to which the currently working transmit beam belongs or the reference signal resource group to which the reference signal resource belongs and all the transmit beams or reference signal resources used for uplink transmission of the terminal device; or

[0111] any one of the transmit beam group to which the currently working transmit beam belongs or the reference signal resource group to which the reference signal resource belongs and all the transmit beams or reference signal resources used for uplink transmission of the terminal device except the transmit beam group to which the currently working transmit beam belongs or the reference signal resource group to which the reference signal resource belongs; or

[0112] The transmit beam group to which the transmit beam that most recently worked before the specified time belongs, or the reference signal resource group to which the reference signal resource belongs, and any transmit beam group or reference signal resource group among all transmit beams or reference signal resources used for uplink transmission of the terminal device, except the transmit beam group to which the transmit beam that most recently worked before the specified time belongs, or the reference signal resource group to which the reference signal resource belongs, for example, before an interval of P, or for another example, before P time slots (s lot), or for another example, before P symbols (symbo l), etc.

[0113] It should be noted that the power back-off value included in the power back-off information, as well as the difference or ratio between the power back-off values, can be an actual value, or can also be an actual value with a difference relative to a certain reference, or can also be the quantization information of the above two actual values, or can also be the level information corresponding to the above two actual values, or can also be the bit positions corresponding to the above two actual values. This embodiment does not make special limitations on this. For example, 1 < x < 2 corresponds to 001.

[0114] In a specific implementation process, the reporting indication can be used to indicate that the constraint conditions of the power back-off value are satisfied.

[0115] In this way, only when the constraint conditions of the power back-off value are satisfied, the terminal device will perform information reporting, which can effectively reduce the resource requirements for the uplink channel and save uplink resources. At the same time, it can also reduce the uplink interference within the system.

[0116] In another specific implementation process, the reporting indication can be used to indicate whether the constraint conditions of the power back-off value are satisfied.

[0117] In this way, directly reporting the judgment result corresponding to the constraint conditions to the network device can simplify the judgment of the constraint conditions of the terminal device, thereby reducing the processing complexity of the terminal device.

[0118] Optionally, in a possible implementation manner of this embodiment, in 210, the terminal device can specifically send the power back-off information corresponding to the at least one transmission beam or reference signal resource to the network device through a physical layer channel.

[0119] Using a physical layer channel for information reporting has a small reporting delay and can quickly notify the network device, so that the network device can quickly obtain information and perform corresponding processes or instructions in a timely manner, thereby realizing reliable uplink transmission of multiple transmission beams.

[0120] Among them, the physical layer channel can include but is not limited to at least one of a Physical Random Access Channel (PRACH) and a Physical Uplink Control Channel (PUCCH). This embodiment does not make special limitations on this.

[0121] In a specific implementation process, the terminal device sends the power back-off information corresponding to the at least one transmission beam or reference signal resource to the network device through the PRACH. This solution design is simple and the standardization is simple. There can be the following several different ways specifically.

[0122] Method 1: The terminal device uses at least one of a specific PRACH time-frequency resource and a specific PRACH sequence parameter to perform uplink transmission to send power fallback information corresponding to at least one transmit beam or reference signal resource to the network device. In this method, less information is transmitted, which can effectively reduce the resource requirements of the system.

[0123] For example, PRACH may only transmit information equivalent to 1 bit as a reporting indication to indicate whether the constraint condition of the power backoff value is met or whether the constraint condition of the power backoff value is met. Since the transmitted information is small, the resource requirements of the system can be effectively reduced. Specifically, for a detailed description of the constraint condition of the power backoff value, please refer to the relevant content in the aforementioned implementation method.

[0124] The network device can configure at least one of the specific PRACH time-frequency resources and the specific PRACH sequence parameters as a reporting indication. Then, when the constraints of the power backoff value are met, or according to the configuration information, the terminal device can specifically use the specific PRACH time-frequency resources and at least one of the specific PRACH sequence parameters to transmit the uplink signal.

[0125] Accordingly, when the constraint condition of the power backoff value is not met, the terminal device may not perform the operation of transmitting the uplink signal using at least one of the specific PRACH time-frequency resources and the specific PRACH sequence parameters.

[0126] After receiving the uplink signal, the network device can determine whether it is necessary to perform the corresponding uplink beam management process based on whether the constraint condition of the power backoff value is satisfied or whether the constraint condition of the power backoff value is satisfied as indicated by the uplink signal. If it is determined that the corresponding uplink beam management process is necessary, the network device can configure or trigger the corresponding uplink beam management process, for example, notifying the terminal device to send SRS to measure the channel quality corresponding to different transmission beams, etc.

[0127] Method 2: The terminal device uses PRACH to perform uplink transmission of detailed reporting information to send power fallback information corresponding to at least one transmit beam or reference signal resource to the network device. In this way, the reporting information is more flexible and rich, which can better assist the network device in making better judgments and decisions, improve the uplink, and improve system performance.

[0128] For example, the terminal device may specifically utilize PRACH to send power backoff values ​​corresponding to one or more transmit beams or reference signal resources to the network device.

[0129] Or, for another example, the terminal device may specifically utilize PRACH to send power backoff values ​​corresponding to one or more transmit beams or reference signal resources, as well as transmit beam indications of the one or more transmit beams or reference signal resource indications of the reference signal resources to the network device.

[0130] Or, for another example, the terminal device may specifically utilize PRACH to send power backoff values ​​corresponding to one or more transmit beam groups or reference signal resource groups to the network device.

[0131] Alternatively, for another example, the terminal device may specifically utilize PRACH to send power backoff values ​​corresponding to one or more transmit beam groups or reference signal resource groups, as well as transmit beam group indications of the one or more transmit beam groups or reference signal resource group indications of the reference signal resource group to the network device.

[0132] Or, for another example, the terminal device may specifically utilize PRACH to send to the network device one or more groups of differences or ratios between power backoff values ​​corresponding to two transmit beams or reference signal resources.

[0133] Alternatively, for another example, the terminal device may specifically utilize PRACH to send to the network device a difference or ratio between power backoff values ​​corresponding to one or more groups of two transmit beams or reference signal resources, as well as a transmit beam indication of the one or more groups of two transmit beams or a reference signal resource indication of the reference signal resources.

[0134] Or, for another example, the terminal device may specifically use PRACH to send to the network device one or more groups of differences or ratios between power backoff values ​​corresponding to two transmit beam groups or reference signal resource groups.

[0135] Alternatively, for another example, the terminal device may specifically utilize PRACH to send to the network device a difference or ratio between power backoff values ​​corresponding to one or more groups of two transmit beam groups or reference signal resource groups, as well as a transmit beam group indication of the one or more groups of two transmit beam groups or a reference signal resource group indication of the reference signal resource group.

[0136] Among them, the detailed description of the one transmit beam or reference signal resource, one transmit beam group or reference signal resource group, two transmit beams or reference signal resources, and two transmit beam groups or reference signal resource groups can be referred to the relevant content of the aforementioned implementation manner.

[0137] In the implementation process, the uplink transmission of the PRACH may be configured as non-contention-based random access (content-free RACH).

[0138] After receiving these detailed reporting information, since the network device contains a lot of information, such as the transmit beam indications of multiple transmit beams or the reference signal resource indications of reference signal resources, and the corresponding power backoff values, the network device can directly determine which uplink transmit beam the terminal device uses from the transmit beam information or reference signal resource information reported by the terminal device, and subsequently notify the terminal device to use the selected transmit beam for uplink transmission.

[0139] In another specific implementation process, the terminal device sends the power backoff information corresponding to the at least one transmit beam or reference signal resource to the network device through PUCCH, which may be in the following different ways.

[0140] Method 1: The terminal device uses a specific PUCCH resource to perform uplink transmission to send power backoff information corresponding to at least one transmit beam or reference signal resource to the network device. In this method, less information is transmitted, which can effectively reduce the resource requirements of the system.

[0141] For example, PUCCH may only transmit information equivalent to 1 bit as a reporting indication to indicate whether the constraint condition of the power backoff value is met or whether the constraint condition of the power backoff value is met. Since the transmitted information is small, the resource requirements of the system can be effectively reduced. Specifically, for a detailed description of the constraint condition of the power backoff value, please refer to the relevant content in the aforementioned implementation method.

[0142] The network device can configure specific PUCCH resources as a reporting indication. Then, when the constraints of the power backoff value are met, or according to the configuration information, the terminal device can specifically use the specific PUCCH resources to transmit the uplink signal.

[0143] Accordingly, when the constraint condition of the power backoff value is not met, the terminal device may not perform the operation of using specific PUCCH resources to transmit uplink signals.

[0144] After receiving the uplink signal, the network device can determine whether it is necessary to perform the corresponding uplink beam management process based on whether the constraint condition of the power backoff value is satisfied or whether the constraint condition of the power backoff value is satisfied as indicated by the uplink signal. If it is determined that the corresponding uplink beam management process is necessary, the network device can configure or trigger the corresponding uplink beam management process, for example, notifying the terminal device to send SRS to measure the channel quality corresponding to different transmission beams, etc.

[0145] Method 2: The terminal device uses PUCCH to perform uplink transmission of detailed reporting information to send power fallback information corresponding to at least one transmit beam or reference signal resource to the network device. In this way, the reporting information is more flexible and rich, which can better assist the network device in making better judgments and decisions, improve the uplink, and improve system performance.

[0146] For example, the terminal device may specifically utilize PUCCH to send power backoff values ​​corresponding to one or more transmit beams or reference signal resources to the network device.

[0147] Or, for another example, the terminal device may specifically utilize PUCCH to send power backoff values ​​corresponding to one or more transmit beams or reference signal resources, as well as transmit beam indications of the one or more transmit beams or reference signal resource indications of the reference signal resources to the network device.

[0148] Or, for another example, the terminal device may specifically utilize PUCCH to send power backoff values ​​corresponding to one or more transmit beam groups or reference signal resource groups to the network device.

[0149] Alternatively, for another example, the terminal device may specifically utilize PUCCH to send power backoff values ​​corresponding to one or more transmit beam groups or reference signal resource groups, as well as transmit beam group indications of the one or more transmit beam groups or reference signal resource group indications of the reference signal resource group to the network device.

[0150] Or, for another example, the terminal device may specifically use PUCCH to send to the network device one or more groups of differences or ratios between power backoff values ​​corresponding to two transmit beams or reference signal resources.

[0151] Alternatively, for another example, the terminal device may specifically utilize PUCCH to send to the network device a difference or ratio between power backoff values ​​corresponding to one or more groups of two transmit beams or reference signal resources, as well as a transmit beam indication of the one or more groups of two transmit beams or a reference signal resource indication of the reference signal resources.

[0152] Or, for another example, the terminal device may specifically use PUCCH to send to the network device one or more groups of differences or ratios between power backoff values ​​corresponding to two transmit beam groups or reference signal resource groups.

[0153] Alternatively, for another example, the terminal device can specifically use PUCCH to send to the network device a difference or ratio between power backoff values ​​corresponding to one or more groups of two transmit beam groups or reference signal resource groups, as well as a transmit beam group indication of the one or more groups of two transmit beam groups or a reference signal resource group indication of the reference signal resource group.

[0154] Among them, the detailed description of the one transmit beam or reference signal resource, one transmit beam group or reference signal resource group, two transmit beams or reference signal resources, and two transmit beam groups or reference signal resource groups can be referred to the relevant content of the aforementioned implementation manner.

[0155] After receiving these detailed reporting information, since the network device contains a lot of information, such as the transmit beam indications of multiple transmit beams or the reference signal resource indications of reference signal resources, and the corresponding power backoff values, the network device can directly determine which uplink transmit beam the terminal device uses from the transmit beam information or reference signal resource information reported by the terminal device, and subsequently notify the terminal device to use the selected transmit beam for uplink transmission.

[0156] Optionally, in a possible implementation of this embodiment, in 210, the terminal device may specifically send the power backoff information corresponding to the at least one transmit beam or reference signal resource to the network device through high-layer signaling.

[0157] High-level signaling is used for information reporting. The signaling design is simple, which can greatly simplify the physical layer protocol process and the implementation process of terminal equipment. At the same time, it enables network equipment to obtain information relatively quickly and perform corresponding processes or instructions in a timely manner, thereby realizing reliable uplink transmission of multiple transmit beams.

[0158] The high-layer signaling may include, but is not limited to, at least one of new MAC CE signaling and MAC CE signaling corresponding to a power status report, which is not particularly limited in this embodiment.

[0159] Specifically, the MAC CE signaling corresponding to the power situation report may include but is not limited to at least one of the following:

[0160] The reserved bit in the MAC CE signaling corresponding to the power situation report;

[0161] The extended bit in the MAC CE signaling corresponding to the power situation report; and

[0162] The power situation reports bits of some existing other fields in the MAC CE signaling corresponding to the power situation report.

[0163] The power situation report may include but is not limited to a power headroom report (Power Headroom Report, PHR), which is not particularly limited in this embodiment.

[0164] In a specific implementation process, a special MAC CE signaling can be designed specifically for the power fallback information corresponding to the at least one transmit beam or reference signal resource reported by the terminal device. In this way, by designing a new MAC CE signaling, it is possible to avoid multiplexing with other existing MAC CEs, thereby increasing flexibility, better matching this scenario, or optimizing for this scenario.

[0165] The new MAC CE signaling corresponds to a MAC subheader, and a field in the MAC subheader, namely the Logical Channel Identify (LCID) field, indicates the representation information of this special MAC CE signaling. The information transmitted by the new MAC CE signaling can be in the following different ways.

[0166] Method 1: The new MAC CE signaling can transmit a power backoff value information. This method can reduce the number of transmission bits and reduce system overhead.

[0167] For a detailed description of the power backoff value information, please refer to the relevant content in the aforementioned implementation manner.

[0168] Figure 3-1 It is a schematic diagram. A row in the figure represents 8 bits, that is, a byte. The other figures are similar and will not be described in detail later. Among them, there can be X reserved bits (R mark, X=2 in the schematic diagram), and the remaining 8-XT bits are used to indicate power backoff value information. T is greater than or equal to 0, because there may be bits occupied for other purposes. This is included in all subsequent embodiments, and will not be described in detail for the sake of simplicity. The value of X can be an integer from 0 to 7.

[0169] Figure 3-2 This is a schematic diagram. There may be X reserved bits in the front and Y reserved bits in the back (R mark, X=2, Y=1 in the schematic diagram), and the remaining 8-XYT bits are used to indicate the power backoff value information. T is greater than or equal to 0, because there may be bits occupied for other purposes. This is included in all subsequent embodiments and will not be repeated for simplicity. The values ​​of X and Y can be integers from 0 to 7 (the sum of X and Y does not exceed 8). If X is 0, there is no reserved bit in the front; if Y is 0, there is no reserved bit in the back.

[0170] Method 2: The new MAC CE signaling can transmit a set of transmit beam or reference signal resource indication information and corresponding power backoff value information. Compared with method 1, this method adds the transmit beam indication information corresponding to the transmit beam or the reference signal resource indication information corresponding to the reference signal resource, which can effectively increase flexibility, for example, it can indicate the power backoff information corresponding to certain specific transmit beams.

[0171] For a detailed description of the sending beam or reference signal resource indication information, and the power backoff value information, please refer to the relevant content in the aforementioned implementation manner.

[0172] For example, in the new MAC CE signaling, the transmit beam or reference signal resource indication information is in front, and the power backoff value information is in the back, and the two occupy one byte respectively. In this way, relatively more bits can be used to represent the information corresponding to the transmit beam or reference signal resource, or the power backoff value information, which can expand the representation range and can be applied to systems with various configurations.

[0173] Figure 3-3 This is a schematic diagram. In the figure, there are X reserved bits in the front and Y reserved bits in the back (R marker, X=2, Y=1 in the schematic diagram), and the remaining 8-XYT bits are used to indicate power backoff value information and transmit beam or reference signal resource indication information. The transmit beam or reference signal resource indication information can be an SRS resource identifier, a CSI-RS resource identifier, or an SSB identifier, or can also be an SRS resource identifier, a CSI-RS resource identifier, or an SSB identifier. The values ​​of X and Y can be integers from 0 to 7 (the sum of X and Y does not exceed 8). If X is 0, there is no reserved bit in the front; if Y is 0, there is no reserved bit in the back. Figure 3-5 is a special case (Y=0).

[0174] Figure 3-4 is a schematic diagram. Figure 3-3 The difference is: Figure 3-3 The number of reserved bits X and Y in the two rows is the same, and Figure 3-4 The number of reserved bits X and Y in the two rows is different, for example, the first row is X and Y (and T), and the second row is X' and Y' (and T'). Figure 3-6 is a special case (Y=Y′=0).

[0175] Or, for another example, in the new MAC CE signaling, the power backoff value information is in front, and the transmit beam or reference signal resource indication information is in the back, and the two occupy one byte respectively. In this way, relatively more bits can be used to represent the information corresponding to the transmit beam or reference signal resource, or the power backoff value information, which can expand the representation range and can be applied to systems with various configurations.

[0176] The difference from the previous example is that the power backoff value information is in the opposite position to the transmit beam or reference signal resource indication information, and the rest is exactly the same. Figure 3-7 to Figure 3-10 Corresponding to Figure 3-3 to Figure 3-6 .

[0177] Or, for another example, in the new MAC CE signaling, the power backoff value information comes first, and the transmit beam or reference signal resource indication information comes second, and the two occupy the same byte.

[0178] Figure 3-11 This is a schematic diagram. There may be X reserved bits in the front and Y reserved bits in the back (R symbol, X=1, Y=1 in the schematic diagram), the remaining A bits are used to indicate the power backoff value information, and B bits are used to indicate the transmit beam or reference signal resource indication information (A=3, B=3 in the schematic diagram). The values ​​of X and Y can be integers from 0 to 7 (the sum of X and Y does not exceed 8), A and B are integers greater than or equal to 1, and A+B+X+Y+T=8 are satisfied. If X is 0, there is no reserved bit in the front; if Y is 0, there is no reserved bit in the back.

[0179] Or, for another example, in the new MAC CE signaling, the transmission beam or reference signal resource indication information comes first, and the power backoff value information comes second, and the two occupy the same byte.

[0180] The difference from the previous example is that the power backoff value information is in the opposite position to the transmit beam or reference signal resource indication information, and the rest is exactly the same.

[0181] Figure 3-12 This is a schematic diagram. There may be X reserved bits in the front and Y reserved bits in the back (R symbol, X=1, Y=1 in the schematic diagram), the remaining A bits are used to indicate the power backoff value information, and B bits are used to indicate the transmit beam or reference signal resource indication information (A=3, B=3 in the schematic diagram). The values ​​of X and Y can be integers from 0 to 7 (the sum of X and Y does not exceed 8), A and B are integers greater than or equal to 1, and A+B+X+Y+T=8 are satisfied. If X is 0, there is no reserved bit in the front; if Y is 0, there is no reserved bit in the back.

[0182] Method 3: Based on method 1, the new MAC CE signaling can transmit multiple power backoff value information.

[0183] In this manner, the order of arranging the multiple power backoff value information may be determined according to the following options:

[0184] Option 1: Determine the arrangement order of multiple power backoff value information according to the position of the reference signal resource information corresponding to the power backoff value information (that is, the reference signal resource corresponding to the corresponding transmit beam) in the RRC configuration signaling.

[0185] Option 2: Determine the order of multiple power backoff value information according to the size of the identifier of the reference signal resource corresponding to the power backoff value information. For example, the order of multiple power backoff value information can be determined from large to small according to the identifier of the signal resource, or the order of multiple power backoff value information can be determined from small to large according to the identifier of the signal resource.

[0186] Option 3: Determine the order of multiple power backoff value information according to the type of reference signal resource corresponding to the power backoff value information. For example, SSB>SRS>CSI-RS, or another example, SSB>CSI-RS>SRS, or another example, SRS>SSB>CSI-RS, or another example, SRS>CSI-RS>SSB, or another example, CSI-RS>SRS>SSB, or another example, CSI-RS>SRS>SSB, or another example, CSI-RS>SSB>SRS, and so on.

[0187] It should be noted that the arrangement order of multiple power backoff value information can be determined by further combining option 1, option 2 and option 3, using two or three options. For example, option 3 can be used first, and then option 1 and option 2 can be used in the same type to further determine the arrangement order of multiple power backoff value information.

[0188] Option 4: The power backoff value information corresponding to a specific transmit beam or reference signal resource is arranged at the front or the back, and the arrangement order of other power backoff value information can be determined by at least one of Option 1, Option 2 and Option 3. For example, the power backoff value information corresponding to the currently working transmit beam or reference signal resource is arranged at the front or the back, or, for another example, the power backoff value information corresponding to the transmit beam or reference signal resource that was most recently working before a specified time (for example, before an interval P, or for another example, before P slots, or for another example, before P symbols, etc.) is arranged at the front or the back.

[0189] In this mode, the bytes occupied by the multiple power backoff value information can be determined according to the following options:

[0190] Option 1: Each power backoff value information occupies one byte (may also include some reserved bits). Figure 3-13 It illustrates the situation where two pieces of power backoff value information each occupy one byte.

[0191] Option 2: Multiple power backoff value information occupies one byte (which may also include some reserved bits). Figure 3-14 and Figure 3-15 It illustrates the situation where two pieces of power backoff value information occupy one byte together.

[0192] In this manner, the new MAC CE signaling may further carry a bit indication to indicate whether a corresponding power backoff value information exists.

[0193] Figure 3-16 This is a schematic diagram. C0 to C5 indicate whether the corresponding power backoff value information is carried in the new MAC CE signaling. For example, 0 may indicate carrying, 1 may indicate not carrying, or for another example, 1 may indicate carrying, 0 may indicate not carrying. Figure 3-16 In the figure, C0, C1, C3 and C5 are set to 1, indicating that they carry the power backoff value information corresponding to the 0th, 1st, 3rd and 5th signal resources respectively, and C2 and C4 are set to 0. Optionally, the order of C0 to C5 in the figure can also be reversed.

[0194] Method 4: Based on method 2, the new MAC CE signaling can transmit multiple group information, that is, multiple transmit beams or reference signal resource indication information, and their corresponding power backoff value information.

[0195] Figure 3-17 to Figure 3-20 This is the case of 2 groups of information, which only illustrates the case of a special number of leading and trailing reserved bits.

[0196] In another specific implementation process, the MAC CE signaling corresponding to the PHR may be reused or extended. This approach avoids designing a new MAC CE signaling, can reduce the workload of standardization, and reduce the processing complexity of terminal devices and network devices.

[0197] The MAC CE signaling corresponding to PHR currently has the following two formats:

[0198] Format 1: Figure 3-21(R represents reserved bits, PH represents power headroom information, and P_CMAX,f,c represents maximum transmit power);

[0199] Format 2: Figure 3-22 (R represents reserved bit, PH represents power margin information, P_CMAX,f,c represents maximum transmit power, P indicates information related to power margin calculation, V indicates information related to P_CMAX,f,c calculation, C7 to C1 respectively indicate by 1 bit whether the power margin and maximum transmit power of the corresponding cell are reported, that is, whether they are carried in this signaling).

[0200] Based on format 1, there are several different ways.

[0201] Method 1: Reuse one reserved bit (can be any one of the above four) in the MAC CE signaling corresponding to the PHR to transmit the reporting indication, to indicate whether the constraint condition of the power backoff value is met, or whether the constraint condition of the power backoff value is met (specifically, the detailed description of the constraint condition of the power backoff value can be found in the relevant content of the aforementioned implementation method.). This method can save bits and reduce overhead.

[0202] Figure 3-23 It is a schematic diagram. In which, X indicates a multiplexed reserved bit (the first reserved bit in the schematic diagram), a value of X of 0 indicates that the power backoff value constraint is not met, and a value of X of 1 indicates that the power backoff value constraint is met.

[0203] Method 2: Multiple (for example, N) reserved bits (can be any N out of 4, or N consecutive bits) in the MAC CE signaling corresponding to the PHR are reused to transmit power backoff value information. This method can reduce the number of transmission bits and reduce system overhead.

[0204] For a detailed description of the power backoff value information, please refer to the relevant content in the aforementioned implementation manner.

[0205] Figure 3-24 It is a schematic diagram, wherein X indicates a multiplexed reserved bit (the first two reserved bits in the schematic diagram), which is used to indicate power backoff value information.

[0206] Method 3: Add multiple (for example, N) extended bits in the MAC CE signaling corresponding to the PHR, which can be used to transmit power backoff value information, or can also be used to transmit the transmit beam or reference signal resource indication information and the corresponding power backoff value information. This method can effectively increase flexibility, add more reporting information or more accurate reporting information, assist network devices in making better judgments, and improve performance.

[0207] Figure 3-25 It is a schematic diagram. Among them, adding multiple extended bits in the MAC CE signaling corresponding to the PHR can be used to indicate the power backoff value information, and the number of reserved bits before and after it can be the same as the existing number of reserved bits in the MAC CE signaling corresponding to the PHR (the existing number is the first 2 reserved bits), and there may be other indications.

[0208] Figure 3-2 to Figure 3-20 You can follow Figure 3-25 A similar approach, with Figure 3-21 In combination with the above, detailed schematic diagrams are no longer provided.

[0209] Based on format 2, there are several different ways.

[0210] Method 1: Reuse one reserved bit (any of the reserved bits can be specified) in the MAC CE signaling corresponding to the PHR to transmit the reporting indication, which is used to indicate whether the constraint condition of the power backoff value is met, or whether the constraint condition of the power backoff value is met (specifically, the detailed description of the constraint condition of the power backoff value can be found in the relevant content of the aforementioned implementation method.). This method can save bits and reduce overhead.

[0211] Figure 3-26 It is a schematic diagram. In which, X indicates a multiplexed reserved bit (the first reserved bit in the schematic diagram), a value of X of 0 indicates that the power backoff value constraint is not met, and a value of X of 1 indicates that the power backoff value constraint is met.

[0212] Method 2: Multiple (for example, N) reserved bits (which may be the two reserved bits corresponding to the row where P_CMAX,f,c is located) in the MAC CE signaling corresponding to the PHR are reused to transmit the power backoff value information. This method can reduce the number of transmission bits and reduce system overhead.

[0213] For a detailed description of the power backoff value information, please refer to the relevant content in the aforementioned implementation manner.

[0214] Figure 3-27 Here, X indicates a multiplexed reserved bit (the two reserved bits corresponding to the first P_CMAX,f,c row in the diagram) which is used to indicate power backoff value information.

[0215] Method 3: Add multiple (for example, N) extended bits in the MAC CE signaling corresponding to the PHR, which can be used to transmit power backoff value information, or can also be used to transmit the transmit beam or reference signal resource indication information and the corresponding power backoff value information. This method can effectively increase flexibility, add more reporting information or more accurate reporting information, assist network devices in making better judgments, and improve performance.

[0216] Figure 3-28 It is a schematic diagram. Among them, adding multiple extended bits in the MAC CE signaling corresponding to the PHR can be used to indicate the power backoff value information, and the number of reserved bits before and after it can be the same as the existing number of reserved bits in the MAC CE signaling corresponding to the PHR (the existing number is the first 2 reserved bits), and there may be other indications.

[0217] Figure 3-2 to Figure 3-20 You can follow Figure 3-28 A similar approach, with Figure 3-22 In combination with the above, detailed schematic diagrams are no longer provided.

[0218] Method 4: multiplex all or part of the bits of the P_CMAX,f,c corresponding field in the MAC CE signaling corresponding to the PHR.

[0219] In this embodiment, power backoff information corresponding to at least one transmit beam or reference signal resource is sent to a network device through a terminal device, so that the network device can quickly obtain information and perform corresponding processes or instructions in a timely manner, thereby achieving reliable uplink transmission of multiple transmit beams.

[0220] In addition, the technical solution provided by this application can greatly improve the user experience.

[0267] The transmission beam or reference signal resource indication refers to identification information used to indicate the transmission beam or reference signal resource, for example, identification information of a certain signal or signal resource.

[0268] The transmission beam group or reference signal resource group indication refers to identification information used to indicate the transmission beam group or reference signal resource group, for example, identification information of a certain signal group or signal resource group.

[0269] In this implementation, the one transmit beam group or reference signal resource group may specifically include but is not limited to the following situations:

[0270] the transmit beam group to which the currently operating transmit beam belongs or the reference signal resource group to which the reference signal resource belongs; or

[0271] A transmit beam group to which a transmit beam that was most recently active before a specified time belongs or a reference signal resource group to which a reference signal resource belongs, for example, before an interval of P, or before P time slots (s lot), or before P symbols (symbo l), etc.; or

[0272] Any one transmission beam group or reference signal resource group among all transmission beams or reference signal resources used for uplink transmission of the terminal device.

[0273] In this implementation, the two transmit beams or reference signal resources may specifically include but are not limited to the following situations:

[0274] Any two transmit beams or reference signal resources among all transmit beams or reference signal resources used for uplink transmission of the terminal device; or

For example, before an interval P, or for another example, before P time slots (s lot), or for another example, before P symbols (symbo l), etc.

[0277] In this implementation manner, the two transmission beam groups or reference signal resource groups may specifically include but are not limited to the following situations:

[0278] Any two transmission beam groups or reference signal resource groups among all the transmission beams or reference signal resources for the uplink transmission of the terminal device; or

For example, before an interval P, or for another example, before P time slots (s lot), or for another example, before P symbols (symbo l), etc.

[0282] It should be noted that the power back-off values included in the power back-off information, as well as the differences or ratios between the power back-off values, may be actual values, or may also be actual values differing relative to a certain reference, or may also be quantization information of the foregoing two actual values, or may also be level information corresponding to the foregoing two actual values, or may also be bit positions corresponding to the foregoing two actual values. This embodiment does not make a special limitation on this. For example, 1 < x < 2 corresponds to 001.

[0283] In a specific implementation process, the reporting indication may be used to indicate that the constraint condition for the power backoff value is satisfied.

[0284] In this way, the terminal device will report information only when the constraint condition of the power backoff value is met, thereby effectively reducing the resource demand for the uplink channel and saving uplink resources. At the same time, it can also reduce the uplink interference in the system.

[0285] In another specific implementation process, the reporting indication may be used to indicate whether the constraint condition of the power backoff value is satisfied.

[0286] In this way, the judgment result corresponding to the constraint condition is directly reported to the network device, which can simplify the judgment of the constraint condition of the terminal device, thereby reducing the processing complexity of the terminal device.

[0287] Optionally, in a possible implementation of this embodiment, the reporting unit 410 may be specifically configured to:

[0288] Sending power backoff information corresponding to the at least one transmit beam or reference signal resource to the network device through a physical layer channel; or

[0289] The power backoff information corresponding to the at least one transmit beam or reference signal resource is sent to the network device through high-layer signaling.

[0290] Among them, the physical layer channel may include but is not limited to at least one of a physical random access channel (Physical Random Access CHanne l, PRACH) and a physical uplink control channel (Physical Uplink Control CHannel, PUCCH), and this embodiment does not specifically limit this.

[0291] In a specific implementation process, the reporting unit 410 sends the power backoff information corresponding to the at least one transmit beam or reference signal resource to the network device through PRACH. This solution is simple in design and standardization. There are several different ways as follows.

[0292] Method 1: The reporting unit 410 can be specifically used to utilize at least one of a specific PRACH time-frequency resource and a specific PRACH sequence parameter for uplink transmission to send power backoff information corresponding to at least one transmit beam or reference signal resource to the network device.

[0293] Method 2: The reporting unit 410 can be specifically used to use PRACH to perform uplink transmission of detailed reporting information to send power backoff information corresponding to at least one transmit beam or reference signal resource to the network device.

[0294] In another specific implementation process, the reporting unit 410 sends the power backoff information corresponding to the at least one transmit beam or reference signal resource to the network device through the PUCCH, which may be in the following different ways.

[0295] Method 1: The reporting unit 410 can be specifically used to utilize specific PUCCH resources for uplink transmission to send power backoff information corresponding to at least one transmit beam or reference signal resource to the network device.

[0296] Method 2: The reporting unit 410 can be specifically used to use PUCCH to perform uplink transmission of detailed reporting information, so as to send power backoff information corresponding to at least one transmit beam or reference signal resource to the network device.

[0297] The high-layer signaling may include, but is not limited to, at least one of new MAC CE signaling and MAC CE signaling corresponding to a power status report, which is not particularly limited in this embodiment.

[0298] Specifically, the MAC CE signaling corresponding to the power situation report may include but is not limited to at least one of the following:

[0299] The reserved bit in the MAC CE signaling corresponding to the power situation report;

[0300] The extended bit in the MAC CE signaling corresponding to the power situation report; and

[0301] The power situation reports bits of some existing other fields in the MAC CE signaling corresponding to the power situation report.

[0302] The power situation report may include but is not limited to a power headroom report (Power Headroom Report, PHR), which is not particularly limited in this embodiment.

[0303] In a specific implementation process, a special MAC CE signaling can be designed specifically for the power fallback information corresponding to the at least one transmit beam or reference signal resource reported by the terminal device. In this way, by designing a new MAC CE signaling, it is possible to avoid multiplexing with other existing MAC CEs, thereby increasing flexibility, better matching this scenario, or optimizing for this scenario.

[0304] The new MAC CE signaling corresponds to a MAC subheader, and a field in the MAC subheader, namely the Logical Channel Identify (LCID) field, indicates the representation information of this special MAC CE signaling. The information transmitted by the new MAC CE signaling can be in the following different ways.

[0305] Method 1: The new MAC CE signaling can transmit a power backoff value information. This method can reduce the number of transmission bits and reduce system overhead.

[0306] Method 2: The new MAC CE signaling can transmit a set of transmit beam or reference signal resource indication information and corresponding power backoff value information.

[0307] The transmit beam or reference signal resource indication information and the power backoff value information each occupy one byte; or the transmit beam or reference signal resource indication information and the power backoff value information together occupy one byte.

[0308] The transmit beam or reference signal resource indication information is before the power backoff value information; or the transmit beam or reference signal resource indication information is after the power backoff value information.

[0309] Method 3: Based on method 1, the new MAC CE signaling can transmit multiple power backoff value information.

[0310] The reporting unit 410 may be further configured to determine an arrangement order of the plurality of power backoff value information according to at least one of the following information:

[0311] The location of the reference signal resource information corresponding to the power backoff value information in the RRC configuration signaling;

[0312] An identifier of a reference signal resource corresponding to the power backoff value information;

[0313] The type of reference signal resource corresponding to the power backoff value information; and

[0314] Power backoff value information corresponding to a specific transmit beam or reference signal resource.

[0315] In this manner, the new MAC CE signaling may further carry a bit indication to indicate whether a corresponding power backoff value information exists.

[0316] Method 4: Based on method 2, the new MAC CE signaling can transmit multiple group information, that is, multiple transmit beams or reference signal resource indication information, and their corresponding power backoff value information.

[0317] In another specific implementation process, the MAC CE signaling corresponding to the PHR may be reused or extended in the following different ways.

[0318] Method 1: The reserved bit in the MAC CE signaling corresponding to the power situation report is transmitted as a reporting indication to indicate whether the constraint condition of the power backoff value is met or whether the constraint condition of the power backoff value is met.

[0319] Method 2: The reserved bit in the MAC CE signaling corresponding to the power situation report transmits the power fallback value information.

[0320] Method three: the extended bit transmission power backoff value information in the MAC CE signaling corresponding to the power situation report, or the transmission beam or reference signal resource indication information and the corresponding power backoff value information.

[0321] Method 4: multiplex all or part of the bits of the P_CMAX,f,c corresponding field in the MAC CE signaling corresponding to the PHR.

[0322] It should be noted that Figure 2 The method executed by the terminal device in the corresponding embodiment can be used to implement the corresponding functions implemented by the terminal device in the above method. Figure 2 The relevant contents in the corresponding embodiments will not be repeated here.

[0323] In this embodiment, power backoff information corresponding to at least one transmit beam or reference signal resource is sent to the network device through the reporting unit, so that the network device can quickly obtain the information and perform the corresponding process or instructions in a timely manner, thereby achieving reliable uplink transmission of multiple transmit beams.
