[0038] First capability information is sent to a network device, where the first capability information is used to indicate a full-power transmission capability corresponding to a power level applied by the terminal.

[0039] In the above embodiment, the terminal reports the full-power transmission capability corresponding to the power level applied by the terminal to the network device by sending the first capability information, so that the network device can know the full-power transmission capability that the terminal can support in actual uplink transmission, which facilitates reasonable and accurate scheduling and ensures uplink performance.

[0132] FIG1 is a schematic diagram showing the architecture of a communication system according to an embodiment of the present disclosure.

[0133] As shown in FIG. 1 , a communication system 100 includes a terminal 101 and a network device 102 .

[0137] In some embodiments, the technical solution of the present disclosure can be applied to the Open RAN architecture. In this case, the interfaces between or within the access network devices involved in the embodiments of the present disclosure can be transformed into internal interfaces of the Open RAN, and the processes and information interactions between these internal interfaces can be implemented through software or programs.

[0138] In some embodiments, the access network device can be composed of a centralized unit (CU) and a distributed unit (DU), where the CU can also be called a control unit. The CU-DU structure can be used to split the protocol layer of the access network device, with the functions of some protocol layers centrally controlled by the CU, and the functions of the remaining part or all of the protocol layers distributed in the DU, which is centrally controlled by the CU, but is not limited to this.

[0139] In some embodiments, the core network device can be a device including one or more network elements, or it can be multiple devices or device groups, each including all or part of one or more network elements. The network element can be virtual or physical. The core network includes, for example, at least one of the Evolved Packet Core (EPC), the 5G Core Network (5GCN), and the Next Generation Core (NGC). Alternatively, the core network device refers to a network element with a specific function, such as the Access Management Function (AMF), the Service Management Function (SMF), etc.

[0140] It can be understood that the communication system described in the embodiment of the present disclosure is for the purpose of more clearly illustrating the technical solution of the embodiment of the present disclosure, and does not constitute a limitation on the technical solution provided by the embodiment of the present disclosure. Ordinary technicians in this field can know that with the evolution of the system architecture and the emergence of new business scenarios, the technical solution provided by the embodiment of the present disclosure is also applicable to similar technical problems.

[0141] The following embodiments of the present disclosure may be applied to the communication system 100 shown in FIG. 1 , or a part of the main body thereof, but are not limited thereto.

[0142] The entities shown in Figure 1 are examples. The communication system may include all or part of the entities in Figure 1, and may also include other entities outside of Figure 1. The number and form of the entities are arbitrary. The connection relationship between the entities is an example. The entities may be connected or disconnected, and the connection may be in any manner, which may be direct or indirect, and may be wired or wireless.

[0143] The embodiments of the present disclosure can be applied to Long Term Evolution (LTE), LTE-Advanced (LTE-A), LTE-Beyond (LTE-B), SUPER 3G, IMT-Advanced, 4th generation mobile communication system (4G), 5th generation mobile communication system (5G), 5G new radio (NR), future radio access (FRA), new radio access technology (RAT), new radio (NR), new radio access (NX), future generation radio access (FX), Global System for Mobile communications (GSM (registered trademark)), CDMA2000, Ultra Mobile Broadband (UMB), IEEE 802.11 (Wi-Fi (registered trademark)), IEEE 802.16 (WiMAX (registered trademark)), IEEE 802.20, Ultra-WideBand (UWB), Bluetooth (registered trademark), Public Land Mobile Network (PLMN) networks, Device-to-Device (D2D) systems, Machine-to-Machine (M2M) systems, Internet of Things (IoT) systems, Vehicle-to-Everything (V2X), systems utilizing other communication processing methods, and next-generation systems based on and extending these.

[0144] In the disclosed embodiment, terminal 101 reports the maximum power level it can support and its corresponding full-power transmission capability. In some scenarios, power backoff is required based on the reported maximum power level. For example, in scenarios where electromagnetic wave absorption ratio or specific absorption rate (SAR) requirements need to be met, or in scenarios where the terminal supports sounding reference signal (SRS) antenna switching to transmit SRS, terminal 101 needs to perform certain power backoff.

[0145] The full-power transmission capability applied by terminal 101 is related to the actual power level used. Therefore, when the power level actually applied by the terminal changes, the conditions or capabilities for supporting full-power transmission may change. Network device 102 cannot know the actual full-power transmission capability supported by terminal 101, which affects base station scheduling and causes uplink performance loss.

[0146] It is necessary for the disclosed embodiment to provide a method for reporting different full-power transmission capabilities according to the fallback situation of the terminal 101.

[0147] FIG2 is an interactive diagram of a method for sending a communication according to an embodiment of the present disclosure. As shown in FIG2 , an embodiment of the present disclosure relates to a method for sending a communication, the method comprising:

[0148] Step S2101 : The terminal 101 sends first capability information to the network device 102 .

[0149] Optionally, terminal 101 supports uplink multi-antenna technology.

[0150] Optionally, the first capability information is used to indicate a full-power transmission capability corresponding to a power level applied by the terminal.

[0151] In some embodiments, the power level applied by the terminal 101 is PC after power backoff based on the maximum power level reported by the terminal 101 .

[0152] Optionally, the terminal 101 may perform backoff according to a power backoff value predefined in the protocol. When the power backoff condition is met, the terminal 101 may determine the PC after the power backoff. For example, the power backoff value (ΔP PowerClass ) can be 3dB or 6dB.

[0153] Optionally, the terminal 101 may independently determine the power level after power backoff, and in this case, the power backoff value may be outside the value defined by the protocol.

[0154] In some embodiments, the first capability information may be full power transmission capability, or other terminal capability information.

[0155] In some embodiments, the first capability information is sent in units of carriers, or the first capability information is sent in units of frequency bands.

[0156] Optionally, in a multi-carrier system, such as a carrier aggregation (CA) or dual connectivity (DC) system, the terminal 101 may report the full power transmission capability corresponding to the applied power level on a per CC or per band basis.

[0157] In some embodiments, full power transmission capability includes at least one of the following:

[0158] The first capability is used to indicate that the terminal supports full power transmission in each power amplifier PA link;

[0159] The second capability is used to indicate that the terminal supports full power transmission on some PA links;

[0160] The third capability is used to indicate that the terminal does not support full-power transmission in all PA links.

[0161] Optionally, the first capability may be ul-FullPwrMode or ul-FullPwrMode-r16. For example, in a scenario where power fallback is not required, the terminal 101's support for the first capability may be determined based on the maximum power level reported by the terminal 101. For example, if the terminal 101 supports the maximum power level transmission on each PA link, the terminal 101 supports the first capability. In a scenario where power fallback is required, the terminal 101 supports the applied power level on each PA link, and the terminal 101 supports the first capability.

[0162] Optionally, the second capability may be ul-FullPwrMode1 or ul-FullPwrMode1-r16.

[0163] Optionally, the third capability may be ul-FullPwrMode2 or ul-FullPwrMode2-r16.

[0164] Optionally, the above three capabilities are for illustration only, and the full power transmission capability may also include other capabilities, or one capability may include multiple sub-capabilities. The terminal 101 may indicate supported capabilities or sub-capabilities based on the first capability information.

[0165] In one example, the third capability ul-FullPwrMode2-r16 includes the following three sub-capabilities: ul-FullPwrMode2-MaxSRS-ResInSet, ul-FullPwrMode2-SRSConfig-diffNumSRSPorts, and ul-FullPwrMode2-TPMIGroup. Among them, ul-FullPwrMode2-MaxSRS-ResInSet indicates that in ul-FullPwrMode2, the terminal 101 supports the maximum number of SRS resources in an SRS resource set set to "codebook". ul-FullPwrMode2-SRSConfig-diffNumSRSPorts indicates that in ul-FullPwrMode2, the SRS configuration supported by the terminal 101, wherein each SRS resource has a different number of antenna ports. ul-FullPwrMode2-TPMIGroup indicates: the transmission precoding matrix indicator (TPMI) group supported by the terminal providing full power.

[0166] In this example, when the terminal 101 indicates support for ul-FullPwrMode2-SRSConfig-diffNumSRSPorts or ul-FullPwrMode2-TPMIGroup, it should also indicate support for ul-FullPwrMode2-MaxSRS-ResInSet.

[0167] In some embodiments, the first capability information is sent by the terminal when a power fallback condition is met.

[0168] For example, when the terminal 101 needs to meet the SAR requirement, it is considered that the power backoff condition is met.

[0169] In some embodiments, the network device 102 receives the first capability information.

[0170] Step S2102 : The terminal 101 sends second capability information to the network device 102 .

[0171] Optionally, the second capability information includes: a maximum power level supported by the terminal, and a full-power transmission capability corresponding to the maximum power level; wherein the power level applied by the terminal is a power level after power fallback based on the maximum power level.

[0172] For example, when the terminal reports the maximum power level of PC1.5, that is, 29dBm, if the supported power fallback value ΔP PowerClass=3dB, indicating that the terminal will fall back to PC2, i.e. 26dBm. If ΔP PowerClass =6dB means the terminal will fall back to PC3, which is 23dBm.

[0173] In some embodiments, the second capability information and the first capability information can be sent through the same capability information, or can be sent using the same signaling, or can be sent separately. For example, terminal 101 can use full power transmission capability to send the first capability information and the second capability information. Alternatively, terminal 101 can first send the second capability information and then send the first capability information.

[0174] In some embodiments, the network device 102 receives the second capability information.

[0175] Optionally, the network device 102 may obtain the PC of the terminal 101 after the fallback, that is, the power level applied by the terminal 101, based on the maximum power level and the power fallback value.

[0176] In some embodiments, the first capability information is used to indicate that the full power transmission capability corresponding to the power level applied by the terminal is the same as the full power transmission capability corresponding to the maximum power level.

[0177] Optionally, in a scenario where terminal 101 reports a maximum power level and requires power backoff, if the full-power transmission capability of the terminal remains unchanged before and after the power backoff, the first capability information may be used to indicate that the full-power transmission capability remains unchanged after the power backoff. For example, the first capability information does not carry a new full-power transmission capability.

[0178] In some embodiments, the first capability information is used to indicate that the full power transmission capability corresponding to the power level of the terminal application is the default capability.

[0179] In one example, the default capability may be the same as the full power transmission capability corresponding to the maximum power level. Alternatively, the default capability may be the first capability ul-FullPwrMode. For example, when terminal 101 reports only the full power transmission capability of the maximum power level, terminal 101 indicates through the first capability information that the full power transmission capability of other power levels is the same. In this case, the first capability information may not occupy any information bits.

[0180] In some embodiments, the first capability information includes:

[0181] The power backoff value and the full power transmission capability corresponding to the power backoff value; wherein the full power transmission capability of the terminal is different before and after power backoff.

[0182] Optionally, in a scenario where the terminal 101 requires power backoff, if the full power transmission capability changes after the power backoff, the terminal 101 may report the full power transmission capability corresponding to the power backoff value.

[0183] In one example, the maximum power level reported by the terminal 101 is PC2, and the full power transmission capability corresponding to the maximum power level is the second capability ul-FullPwrMode1 or the third capability ul-FullPwrMode2. The power fallback value supported by the terminal 10 when performing power fallback is 3dB, that is, ΔP PowerClass =3dB, the corresponding full power transmission capability after power backoff changes to the first capability ul-FullPwrMode. The capability information reported by the terminal 101 can be referred to as shown in Table 1:

[0184] Table 1

[0185] In this example, when terminal 101 performs power fallback, the full-power transmission capability changes, which can be reported through first capability information. The first capability information may include the information in the third row of Table 1, and the second capability information may include the information in the second row of Table 1; alternatively, the first capability information and the second capability information may be reported through the same capability information, which includes the information in Table 1.

[0186] Optionally, the first capability information includes multiple different power backoff values ​​and the full power transmission capability corresponding to each power backoff value.

[0187] Among them, if the power backoff values ​​supported by the terminal 101 in different backoff scenarios are different, or if the terminal 101 supports multiple power backoff values, the terminal 101 can report the full power transmission capabilities corresponding to different power backoff values ​​respectively.

[0188] In one example, the maximum power level reported by the terminal 101 is PC1.5, and the full power transmission capability corresponding to the maximum power level is the second capability ul-FullPwrMode1. The power fallback values ​​supported by the terminal 101 include: ΔP PowerClass =3dB or ΔP PowerClass =6dB. In the two cases of power backoff, compared with the full power transmission capability corresponding to PC1.5, the terminal 101 has a power backoff of ΔP PowerClass =3dB The supported full power transmission capability changes to the third capability ul-FullPwrMode2. The terminal 101 is in ΔP PowerClass =6dB supports the full power transmission capability to change to the first capability ul-FullPwrMode. Referring to Table 2, in this example, the terminal 101 can report the full power transmission capability corresponding to different power backoff values ​​through the first capability information.

[0189] Table 2

[0190] In this example, when terminal 101 performs power fallback, the full-power transmission capability changes, which can be reported through first capability information. The first capability information may include the information in the third and fourth rows of Table 2, and the second capability information may include the information in the second row of Table 1; alternatively, the first capability information and the second capability information may be reported through the same capability information, which includes the information in Table 2.

[0191] In other examples, the maximum power level reported by the terminal 101 may be PC2, and the corresponding full-power transmission capability is the first capability ul-FullPwrMode, which records that each PA link supports full-power transmission.

[0192] In some embodiments, the examples in Table 1 and Table 2 are for illustration only. For example, the terminal 101 may also indicate other full-power transmission capabilities corresponding to different power backoff values, such as different sub-capabilities of the second capability.

[0193] In some embodiments, the first capability information includes:

[0194] The full-power transmission capability corresponding to the terminal power fallback; wherein, the power level of the terminal application changes or the maximum power level changes.

[0195] Optionally, in this embodiment, the power backoff value for power backoff performed by the terminal 101 may be a value defined by the protocol, or a value other than the value defined by the protocol, or a value determined by the terminal 101 itself.

[0196] Optionally, in this embodiment, when the applied power level changes or the maximum power level changes, the terminal 101 may report the full power transmission capability after the change.

[0197] In some embodiments, for the first capability information in the above embodiments, the terminal 101 may dynamically report the first capability information when the power fallback condition is met.

[0198] In some embodiments, the first capability information includes:

[0199] At least one power level supported by the terminal, and the full power transmission capability corresponding to each power level.

[0200] Optionally, in this embodiment, the terminal 101 can statically report the full power transmission capability corresponding to the supported power level at one time. As shown in reference Table 3, the terminal 101 reports the supported multiple power levels and the full power transmission capability corresponding to each power level in the first capability information, including the maximum power level and other power levels.

[0201] Table 3

[0202] Optionally, in this embodiment, step S2102 may be omitted.

[0203] Optionally, the full-power transmission capability corresponding to the power level of the terminal application is the same as the full-power transmission capability corresponding to the maximum power level, or the full-power transmission capability corresponding to the power level of the terminal application is the default capability; wherein, at least one power level is the maximum power level.

[0204] For example, if the full power transmission capability supported by the terminal 101 remains unchanged before and after power fallback, the terminal 101 may indicate through the first capability information that the corresponding capability remains unchanged, that is, the full power transmission capability is the same as that corresponding to the maximum power level.

[0205] For another example, if the terminal 101 only reports the full power transmission capability corresponding to the maximum power level, and the terminal 101 also supports other power levels, the full power transmission capability supported by the other power levels may be defaulted as the default capability.

[0206] Optionally, the default capability may be the capability corresponding to the maximum power level, or the first capability ul-FullPwrMode.

[0207] In some embodiments, the network device 102 receives the second capability information.

[0288] The method of the embodiment of the present disclosure provides a method for a terminal to report the full power transmission capability corresponding to each power when reporting power or power fallback. To facilitate understanding of the embodiment of the present disclosure, some examples are listed below:

[0289] Example 1:

[0290] The terminal reports power backoff ΔP PowerClass At the same time, it also reports the full power transmission capability it supports.

[0291] In one embodiment, if the full power transmission capability supported by the terminal does not change after the fallback, the terminal may indicate that its full power transmission capability remains unchanged.

[0292] When only the full power transmission capability of the highest supported level is reported, it can be assumed that other power levels support the corresponding full power transmission capability as ul-FullPwrMode.

[0293] In another embodiment, if the full power transmission capability supported by the terminal changes after the fallback, the full power transmission capability supported by the terminal is also reported.

[0294] Optionally, as shown in Table 1, the terminal reports the PC2 power level, and the full power transmission capability it supports is ul-FullPwrMode1 or ul-FullPwrMode2. PowerClass =3dB, the full power transmission capability it supports changes. Therefore, when reporting power backoff, the terminal can also report the full power transmission capability it supports.

[0295] Optionally, as shown in Table 2, the terminal reports the PC1.5 power level, and the full power transmission capability it supports is ul-FullPwrMode1. When it falls back to ΔP PowerClass =3dB or 6dB, since the full power transmission capability it supports changes, the terminal can report its supported full power transmission capability at the same time as reporting power backoff.

[0296] Optionally, ul-FullPwrMode2 may correspond to three sub-capabilities: ul-FullPwrMode2-MaxSRS-ResInSet, ul-FullPwrMode2-SRSConfig-diffNumSRSPorts, and ul-FullPwrMode2-TPMIGroup. Table 1 is only an illustrative embodiment. In practice, the above three sub-capabilities may be reported based on actual support conditions.

[0297] Example 2:

[0298] The terminal statically reports the full power transmission capability corresponding to each power level at one time. For example, refer to Table 3.

[0299] In one embodiment, if the full power transmission capability supported by the terminal does not change after the fallback, the terminal may indicate that its full power transmission capability remains unchanged.

[0300] When only the full power transmission capability of the highest supported level is reported, it can be assumed that other power levels support the corresponding full power transmission capability as ul-FullPwrMode.

[0301] Example 3:

[0302] When a terminal dynamically reports its supported full power transmission capability, the trigger condition is when the maximum power of the terminal changes and the corresponding full power transmission capability changes.

[0303] Optionally, in Example 1, the terminal reports power backoff ΔP PowerClass The corresponding capability information can be reported at the same time. In Example 3, the terminal can report power fallback and the corresponding capability information at different times.

[0304] Example 4:

[0305] Based on the above example, in a multi-carrier system such as CA, DC, etc., the base station may perform indication based on per CC or per band.

[0306] The embodiments of the present disclosure further provide an apparatus for implementing any of the above methods. For example, an apparatus is provided, comprising units or modules for implementing each step performed by a terminal in any of the above methods. For another example, another apparatus is provided, comprising units or modules for implementing each step performed by a network device (e.g., an access network device, a core network function node, a core network device, etc.) in any of the above methods.

[0307] It should be understood that the division of the various units or modules in the above device is merely a division of logical functions. In actual implementation, they may be fully or partially integrated into a physical entity, or they may be physically separated. In addition, the units or modules in the device may be implemented in the form of a processor calling software: for example, the device includes a processor, the processor is connected to a memory, and the memory stores instructions. The processor calls the instructions stored in the memory to implement any of the above methods or implement the functions of the various units or modules of the above device, wherein the processor is, for example, a general-purpose processor, such as a central processing unit (CPU) or a microprocessor, and the memory is a memory within the device or a memory outside the device. Alternatively, the units or modules in the device can be implemented in the form of hardware circuits, and the functions of some or all of the units or modules can be realized by designing the hardware circuits. The above-mentioned hardware circuits can be understood as one or more processors; for example, in one implementation, the above-mentioned hardware circuit is an application-specific integrated circuit (ASIC), which realizes the functions of some or all of the above units or modules by designing the logical relationship of the components in the circuit; for example, in another implementation, the above-mentioned hardware circuit can be realized by a programmable logic device (PLD). Taking a field programmable gate array (FPGA) as an example, it can include a large number of logic gate circuits, and the connection relationship between the logic gate circuits is configured by configuring the configuration file, thereby realizing the functions of some or all of the above units or modules. All units or modules of the above devices can be realized in the form of software called by the processor, or in the form of hardware circuits, or in part by the form of software called by the processor, and the rest by hardware circuits.

[0308] In the embodiments of the present disclosure, the processor is a circuit with signal processing capabilities. In one implementation, the processor can be a circuit with instruction reading and execution capabilities, such as a central processing unit (CPU), a microprocessor, a graphics processing unit (GPU) (which can be understood as a microprocessor), or a digital signal processor (DSP). In another implementation, the processor can implement certain functions through the logical relationship of the hardware circuit. The logical relationship of the above-mentioned hardware circuit is fixed or reconfigurable. For example, the processor is a hardware circuit implemented by an application-specific integrated circuit (ASIC) or a programmable logic device (PLD), such as an FPGA. In a reconfigurable hardware circuit, the process of the processor loading a configuration document and implementing the hardware circuit configuration can be understood as the process of the processor loading instructions to implement the functions of some or all of the above units or modules.
