The capability information is also used by the network device to determine whether to allow the terminal to report power margin using the MPR value based on the uplink carrier aggregation capability.

[0050] In the above embodiments, by having the terminal send capability information to the network device, the capability information is used to indicate that the terminal supports the MPR value based on the uplink carrier aggregation capability when performing uplink carrier aggregation in the first frequency band. This allows the network device to receive the capability information sent by the terminal and, based on the capability information, determine whether the terminal is allowed to use the MPR value based on the uplink carrier aggregation capability to report power margin.

The first indication information is used to instruct the network device to allow the terminal to report power margin using the MPR value based on uplink carrier aggregation capability, so that the terminal can promptly know the decision result of the network device and thus execute subsequent processes according to the instructions of the network device.

[0054] In conjunction with some embodiments of the first aspect, in some embodiments, the method further includes:

[0055] Upon receiving the first indication information sent by the network device, the power margin is reported using the MPR value based on the uplink carrier aggregation capability.

[0066] In conjunction with some embodiments of the first aspect, in some embodiments, the method further includes:

[0067] If neither the first indication information nor the second indication information is received, the original MPR value is used to report the power margin.

[0068] In the above embodiments, when the terminal does not receive the second instruction information sent by the network device, the terminal uses the original MPR value to report the power margin, so as to ensure that the power margin can still be reported even when the terminal does not receive an explicit instruction from the network device, thus ensuring the integrity of the communication process.

[0166] It is understood that the communication system described in this disclosure is for the purpose of more clearly illustrating the technical solutions of this disclosure, and does not constitute a limitation on the technical solutions proposed in this disclosure. As those skilled in the art will know, with the evolution of system architecture and the emergence of new business scenarios, the technical solutions proposed in this disclosure are also applicable to similar technical problems.

[0167] The following embodiments of this disclosure can be applied to the communication system 100 shown in FIG1, or to some of the main bodies, but are not limited thereto. The main bodies shown in FIG1 are illustrative. The communication system may include all or some of the main bodies in FIG1, or may include other main bodies outside of FIG1. ​​The number and form of each main body are arbitrary. Each main body may be physical or virtual. The connection relationship between the main bodies is illustrative. The main bodies may not be connected or may be connected. The connection can be in any way, it can be a direct connection or an indirect connection, it can be a wired connection or a wireless connection.

[0168] The embodiments disclosed herein 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), CDMA2000, Ultra Mobile Broadband (UMB), IEEE 802.11 (Wi-Fi), IEEE 802.16 (WiMAX), and IEEE 802.20, Ultra-Wideband (UWB), Bluetooth (a 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, systems utilizing other communication methods, and next-generation systems built upon them, etc. Furthermore, multiple systems can be combined (e.g., a combination of LTE or LTE-A with 5G).

[0169] In some embodiments, considering the radio frequency implementation of the terminal in the 5G system, for continuous uplink carrier aggregation and non-continuous uplink carrier aggregation within the FR2 band, the MPR value to be used can be determined based on the downlink carrier aggregation capability of the carrier aggregation.

[0170] In some embodiments, for continuous carrier aggregation and non-continuous carrier aggregation within the FR2 band, the uplink carrier aggregation capability is less than or equal to the downlink carrier aggregation capability. For example, if uplink supports 3-carrier aggregation, downlink may support 6-carrier aggregation, which may cause the terminal to use a relatively large MPR value when reporting the Power Headroom Report (PHR).

[0171] With the continuous advancement of technology, terminals can adopt new radio frequency implementation methods. For example, uplink and downlink can use independent local oscillators. Then, for continuous uplink carrier aggregation and non-continuous uplink carrier aggregation in the FR2 band, the corresponding MPR value can be adopted based on the uplink carrier aggregation capability of the carrier aggregation to further improve the uplink coverage of the millimeter wave band.

[0172] In view of this, the terminal can report relevant capabilities to the network device so that the terminal can adopt the corresponding MPR value according to the uplink carrier aggregation capability.

[0173] Figure 2 is an interactive schematic diagram of a communication method according to an embodiment of the present disclosure. As shown in Figure 2, the embodiments of the present disclosure relate to a communication method, which includes:

[0174] Step S2101: The terminal sends capability information to the network device.

[0175] In some embodiments, the RF implementation of the terminal supports reporting power margin using an MPR value based on the uplink carrier aggregation capability when the terminal performs uplink carrier aggregation in the first frequency band.

[0176] In some embodiments, the network device receives capability information sent by the terminal.

[0177] In some embodiments, capability information is used to indicate the MPR value supported by the terminal when performing uplink carrier aggregation in the first frequency band.

[0178] In some embodiments, the capability information is used to indicate that the terminal supports an MPR value based on uplink carrier aggregation capability when performing uplink continuous carrier aggregation in the first frequency band. Alternatively, the capability information is used to indicate that the terminal supports an MPR value based on uplink carrier aggregation capability when performing uplink non-contiguous carrier aggregation in the first frequency band.

[0179] In some embodiments, the terms "uplink", "uplink", and "physical uplink" can be used interchangeably, as can the terms "downlink", "downlink", and "physical downlink", as well as the terms "sidelink", "sidelink", "sidelink communication", "sidelink communication", "direct connection", "direct link", "direct communication", and "direct link communication".

[0180] In some embodiments, the name of the capability information is not limited, and it may be, for example, "first capability information", "capability indication information", "capability indication", etc.

[0181] In some embodiments, the names of information, etc., are not limited to the names described in the embodiments. Terms such as "information", "message", "signal", "signaling", "report", "configuration", "indication", "instruction", "command", "channel", "parameter", "domain", "field", "symbol", "symbol", "codebook", "codeword", "codepoint", "bit", "data", "program", and "chip" can be used interchangeably.

[0182] In some embodiments, each first frequency band corresponds to a capability information, or in other words, the capability information is band-specific. That is, the capabilities exhibited by the terminal on different first frequency bands may be different. For example, when the terminal performs uplink carrier aggregation in one first frequency band, it supports an MPR value based on the uplink carrier aggregation capability, while when performing uplink carrier aggregation in another first frequency band, it may not support an MPR value based on the uplink carrier aggregation capability.

[0183] In some embodiments, a band combination of the first frequency band corresponds to a capability information, or in other words, the capability information is band combination specific (per band combination). That is, the capabilities exhibited by the terminal in different band combinations of the first frequency band may be different. For example, when the terminal performs uplink carrier aggregation on a certain band combination of the first frequency band, it supports an MPR value based on uplink carrier aggregation capability, while when performing uplink carrier aggregation on another band combination of the first frequency band, it may not support an MPR value based on uplink carrier aggregation capability.

[0184] In step S2102, the network device determines, based on the capability information, whether to allow the terminal to report power margin using the MPR value based on uplink carrier aggregation capability.

[0185] In some embodiments, the network device determines whether to allow the terminal to report power margin using the MPR value based on uplink carrier aggregation capability, based on capability information and the current network conditions.

[0186] In some embodiments, if the current network conditions meet the requirements, the network device may determine, based on capability information, that the terminal is allowed to report power margin using the MPR value based on uplink carrier aggregation capability; conversely, if the current network conditions do not meet the requirements, even if the terminal's capability information is received, the network device may determine that the terminal is not allowed to report power margin using the MPR value based on uplink carrier aggregation capability.

[0187] In some embodiments, the current network situation may include the current network state and / or the current configuration on the network side, but is not limited thereto.

[0188] In some embodiments, the current network state may include, but is not limited to, the level of interference between different carriers.

[0189] For example, if the interference between different carriers is controlled within an acceptable range, the network device can determine, based on capability information, whether the terminal is allowed to report power margin using the MPR value based on uplink carrier aggregation capability. Conversely, if the interference between different carriers is not controlled within an acceptable range, even if the terminal's capability information is received, the network device can determine whether the terminal is not allowed to report power margin using the MPR value based on uplink carrier aggregation capability.

[0190] In some embodiments, the current configuration on the network side may include whether the network device supports an MPR value based on uplink carrier aggregation capability, but is not limited thereto.

[0191] For example, if a network device supports an MPR value based on uplink carrier aggregation capability, it can determine, based on capability information, whether or not the terminal is allowed to report power margin using an MPR value based on uplink carrier aggregation capability. Conversely, if the network device does not support an MPR value based on uplink carrier aggregation capability, even if it receives the terminal's capability information, it can still determine that the terminal is not allowed to report power margin using an MPR value based on uplink carrier aggregation capability.

[0192] In some embodiments, the network device determines that the terminal is allowed to report power margin using an MPR value based on uplink carrier aggregation capability, and the network device may send a first indication message to the terminal.

[0193] In some embodiments, the first indication information is used to instruct the network device to allow the terminal to report power margin using an MPR value based on uplink carrier aggregation capability.

[0194] In some embodiments, the terminal receives first instruction information sent by the network device.

[0195] In some embodiments, the name of the first instruction information is not limited, and it may be, for example, "first instruction", "first information", "permission instruction", "license instruction", etc.

[0196] In some embodiments, a first signaling message may be used as a carrier of a first instruction message, which is used to control and manage resource allocation.

[0197] In some embodiments, the terms “resource,” “resource set,” “resource group,” “precoding,” “precoder,” “weight,” “precoding weight,” “quasi-co-location (QCL),” “transmission configuration indication (TCI) status,” “spatial relation,” “spatial domain filter,” “transmission power,” “phase rotation,” “antenna port,” “antenna port group,” “layer,” “the number of layers,” “rank,” “beam,” “beam width,” “beam angular degree,” “antenna,” “antenna element,” and “panel” can be used interchangeably.

[0198] In some embodiments, the network device may send a first signaling message to the terminal, the first signaling message including first indication information.

[0199] In some embodiments, the terminal may receive a first signaling sent by the network device to receive the first indication information.

[0200] In some embodiments, the first signaling may be a Medium Access Control (MAC) control element (CE), or the first signaling may be downlink control information (DCI) signaling.

[0201] In some embodiments, the terms “downlink control information (DCI),” “downlink (DL) assignment,” “DL DCI,” “uplink (UL) grant,” and “UL DCI” can be used interchangeably.

[0202] In some embodiments, when a terminal receives a first indication message sent by a network device, the terminal may report power margin using an MPR value based on uplink carrier aggregation capability.

[0203] In some embodiments, the terminal may use an MPR value based on uplink carrier aggregation capability to report PHR to the network device in order to report power margin.

[0204] In some embodiments, the terminal can determine its current maximum transmission power based on the MPR value based on uplink carrier aggregation capability, and then send a PHR indicating the terminal's current maximum transmission power to the network device to achieve power margin reporting.

[0205] In some embodiments, if the network device determines that the terminal is not allowed to report power headroom using the MPR value based on uplink carrier aggregation capability, the network device may not send the first indication information to the terminal. Accordingly, the terminal cannot receive the first indication information sent by the network device.

[0206] In some embodiments, if the terminal does not receive the first indication information sent by the network device, the terminal may use the original MPR value to report the power margin.

[0207] In some embodiments, the terminal may use the original MPR value to report the PHR to the network device in order to report the power margin.

[0208] In some embodiments, the terminal can determine its current maximum transmission power based on the original MPR value, and then send a PHR indicating the terminal's current maximum transmission power to the network device to report the power margin.

[0209] The above embodiment is illustrated by taking the control of the power margin reporting process between the network device and the terminal through the interaction of the first indication information as an example. In more possible implementations, the network device determines that the terminal is not allowed to use the MPR value based on the uplink carrier aggregation capability to report the power margin, and the network device can send the second indication information to the terminal.

[0210] In some embodiments, the second indication information is used to instruct the network device not to allow the terminal to report power margin using the MPR value based on uplink carrier aggregation capability.

[0211] In some embodiments, the terminal receives second instruction information sent by the network device.

[0212] In some embodiments, the name of the first instruction information is not limited, and it may be, for example, "second instruction", "second information", "prohibition instruction", "rejection instruction", etc.

[0213] In some embodiments, a first signaling message may be used as a carrier of the second instruction information, and the first signaling message may be used to control and manage resource allocation.

[0214] In some embodiments, the network device may send a first signaling message to the terminal, the first signaling message including second indication information.

[0215] In some embodiments, the terminal may receive a first signaling sent by the network device to receive the second instruction information.

[0216] In some embodiments, the first signaling may be MAC CE, or the first signaling may be DCI signaling.

[0217] In some embodiments, when a terminal receives a second indication message sent by a network device, the terminal may use the original MPR value to report the power margin.

[0218] In some embodiments, the terminal may use the original MPR value to report the PHR to the network device in order to report the power margin.

[0219] In some embodiments, the terminal can determine its current maximum transmission power based on the original MPR value, and then send a PHR indicating the terminal's current maximum transmission power to the network device to report the power margin.

[0220] In some embodiments, when the power margin reporting process is controlled by the network device and the terminal through the exchange of first and second indication information, the terminal may not receive the indication information sent by the network device even if the network device sends indication information to the terminal.

[0221] In some embodiments, if the terminal does not receive the first indication information and the second indication information sent by the network device, the terminal may use the original MPR value to report the power margin.

[0222] In some embodiments, the terminal may use the original MPR value to report the PHR to the network device in order to report the power margin.

[0223] In some embodiments, the terminal can determine its current maximum transmission power based on the original MPR value, and then send a PHR indicating the terminal's current maximum transmission power to the network device to report the power margin.

[0238] In some embodiments, the network device receives capability information sent by the terminal.

[0239] In some embodiments, capability information is used to indicate the MPR value supported by the terminal when performing uplink carrier aggregation in the first frequency band.

[0240] In some embodiments, the capability information is used to indicate that the terminal supports an MPR value based on uplink carrier aggregation capability when performing uplink continuous carrier aggregation in the first frequency band. Alternatively, the capability information is used to indicate that the terminal supports an MPR value based on uplink carrier aggregation capability when performing uplink non-contiguous carrier aggregation in the first frequency band.

[0241] In some embodiments, each first frequency band corresponds to a capability information, or in other words, the capability information is band-specific. That is, the capabilities exhibited by the terminal on different first frequency bands may be different. For example, when the terminal performs uplink carrier aggregation in one first frequency band, it supports an MPR value based on the uplink carrier aggregation capability, while when performing uplink carrier aggregation in another first frequency band, it may not support an MPR value based on the uplink carrier aggregation capability.

[0242] In some embodiments, a band combination of the first frequency band corresponds to a capability information, or in other words, the capability information is band combination specific (per band combination). That is, the capabilities exhibited by the terminal in different band combinations of the first frequency band may be different.

[0254] The above embodiment illustrates the example of a network device allowing a terminal to report power headroom using an MPR value based on uplink carrier aggregation capability. In more possible implementations, the network device may also disallow the terminal from reporting power headroom using an MPR value based on uplink carrier aggregation capability, and the network device may not send the first indication information to the terminal.

[0279] The above embodiment is illustrated by the example of the terminal receiving the second indication information sent by the network device when the network device does not allow the terminal to report power margin using the MPR value based on uplink carrier aggregation capability. In more possible implementations, even if the network device sends indication information to the terminal, the terminal may not receive the indication information sent by the network device.

[0280] In some embodiments, if the terminal does not receive the first indication information and the second indication information sent by the network device, the terminal may use the original MPR value to report the power margin.

[0281] The communication method involved in the embodiments of this disclosure may include at least one of steps S3201 to S3204.

[0284] According to the solution provided in the embodiments of this disclosure, the terminal can report capability information, which is used to indicate that the terminal supports an MPR value based on uplink carrier aggregation capability when uplink continuous or non-continuous carrier aggregation is performed in the frequency band.

[0285] In some embodiments, after receiving the terminal's capability information, the network side instructs the terminal to use an MPR value based on uplink carrier aggregation capability under the current configuration through MEC CE or DCI signaling. Then, the terminal uses the corresponding optimized MPR value to report PHR according to the network instruction.

[0286] In some embodiments, after receiving the terminal's capability information, the network side does not provide any indication signaling, and the terminal uses the original MPR value to report the PHR.

[0287] In some embodiments, this capability information is reported per band per band combination.

[0288] In some embodiments, this capability information applies not only to 5G scenarios but also to MIMO and TxD scenarios.
