[0177] 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.

[0178] 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.

[0179] 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).

[0180] In some embodiments, if there is no coexistence problem between adjacent in-band and out-of-band networks, or if the network's system bandwidth is greater than the channel bandwidth configured for the terminal, the radio frequency performance of protecting adjacent channel users can be further reduced, thereby further increasing the terminal's transmit power and enhancing the terminal's UL coverage.

[0181] In some embodiments, the terms "uplink", "uplink", and "physical uplink" can be used interchangeably.

[0182] In some embodiments, the terms "transmission power", "precoding", "precoder", "weight", "precoding weight", "quasi-co-location (QCL)", "transmission configuration indication (TCI) status", "spatial relation", "spatial domain filter", "phase rotation", "antenna port", "antenna port group", "layer", "the number of layers", "rank", "resource", "resource set", "resource group", "beam", "beam width", "beam angular degree", "antenna", "antenna element", and "panel" can be used interchangeably.

[0183] In some embodiments, the network device can determine whether there is a coexistence problem between adjacent in-band and out-of-band devices. If there is no coexistence problem between adjacent in-band and out-of-band devices, the device can instruct the terminal to reduce the radio frequency index of the protection channel user. This allows the terminal to use the optimized MPR to report power margin when there is no coexistence problem between adjacent in-band and out-of-band devices, thereby improving the terminal's transmit power.

[0184] In some embodiments, the network device can determine the relationship between the network's system bandwidth and the terminal's channel bandwidth. If the network's system bandwidth is greater than the terminal's channel bandwidth, the device can instruct the terminal to reduce the radio frequency index for protecting adjacent channel users. This allows the terminal to use an optimized MPR for power margin reporting when the network's system bandwidth is greater than the terminal's channel bandwidth, thereby increasing the terminal's transmit power.

[0185] In some embodiments, reducing the radio frequency metrics for protecting adjacent channel users can be achieved by shifting the edge of the terminal's channel bandwidth (BW) in the currently configured radio frequency metrics template outward.

[0186] For example, the channel bandwidth of the terminal in the currently configured RF indicator template can be shifted outward by X MHz. Referring to Figures 2A and 2B, Figure 2A is a schematic diagram of an RF indicator template according to an embodiment of this disclosure, and Figure 2B is a schematic diagram of shifting an RF indicator template according to an embodiment of this disclosure. As shown in Figures 2A and 2B, the channel bandwidth of the terminal in the RF indicator template shown in Figure 2A can be shifted outward by X MHz to obtain the RF indicator template shown in Figure 2B. Here, X can be any positive value.

[0187] In some embodiments, reducing the radio frequency (RF) metrics for protecting adjacent channel users can also involve relaxing the currently configured RF metric template by Y dB. Here, Y can be any positive value.

[0188] It should be noted that not all terminals support power margin reporting using the optimized MPR. Therefore, in addition to considering whether adjacent in-band / out-of-band networks can coexist or whether the network's system bandwidth is greater than the channel bandwidth allocated to the terminal, network devices also need to make a decision based on the terminal's device capabilities.

[0189] Figure 3 is an interactive schematic diagram of a communication method according to an embodiment of the present disclosure. As shown in Figure 3, the embodiments of the present disclosure relate to a communication method, which includes:

[0190] Step S3101: The terminal sends capability information to the network device.

[0191] In some embodiments, terms such as “send,” “transmit,” “report,” “distribute,” “transfer,” “bidirectional transmission,” “send and / or receive” can be used interchangeably.

[0192] In some embodiments, capability information is used to indicate that the terminal supports MPR optimization in a first frequency band.

[0193] In some embodiments, the first frequency band is a frequency band number supported by the terminal. For example, if the first frequency band is a frequency band number nX supported by the terminal, then the capability information can be used to indicate that the terminal supports MPR optimization on frequency band nX.

[0194] 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.

[0195] 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.

[0196] In some embodiments, the terminal can support multiple frequency bands, that is, the terminal can support multiple first frequency bands. Each first frequency band can correspond to a capability information, or in other words, each frequency band nX can correspond to a capability information.

[0197] In some embodiments, a network device may receive capability information sent by a terminal.

[0198] In some embodiments, “receive,” “acquire,” “get,” “obtain,” “transmit,” “bidirectional transmission,” and “send and / or receive” can be used interchangeably and can be interpreted as receiving from other entities, obtaining from protocols, obtaining from higher layers, obtaining through self-processing, or autonomous implementation, among other meanings.

[0199] In step S3102, the network device determines, based on the capability information, whether to allow the terminal to report power margin using the optimized MPR value.

[0200] In some embodiments, the network device determines whether to allow the terminal to report power margin using the optimized MPR value based on capability information and network status information.

[0201] It should be noted that the reporting of power headroom can also be called the reporting of a Power Headroom Report (PHR).

[0202] In some embodiments, if the network status information meets the requirements, the network device may determine, based on the capability information, that the terminal is allowed to report power margin using the optimized MPR value; conversely, if the network status information does not meet the requirements, even if the network device receives the terminal's capability information, it may determine that the terminal is not allowed to report power margin using the optimized MPR value.

[0203] In some embodiments, network status information can be used to indicate at least one of the following: whether there is adjacent frequency band interference in the first frequency band, whether there is adjacent out-of-band interference in the first frequency band, and whether the system bandwidth of the network device is greater than the channel bandwidth of the terminal.

[0204] In some embodiments, network status information is used to indicate whether there is adjacent frequency band interference in the first frequency band. If the network status information indicates that there is no adjacent frequency band interference in the first frequency band, the network device can determine, based on capability information, that the terminal is allowed to report power margin using the optimized MPR value. Conversely, if the network status information indicates that there is adjacent frequency band interference in the first frequency band, even if the network device receives the terminal's capability information, it will determine that the terminal is not allowed to report power margin using the optimized MPR value.

[0205] In some embodiments, network status information is used to indicate whether there is adjacent out-of-band interference in the first frequency band. If the network status information indicates that there is no adjacent out-of-band interference in the first frequency band, the network device can determine, based on capability information, that the terminal is allowed to report power margin using the optimized MPR value. Conversely, if the network status information indicates that there is adjacent out-of-band interference in the first frequency band, even if the network device receives the terminal's capability information, it will determine that the terminal is not allowed to report power margin using the optimized MPR value.

[0206] In some embodiments, network status information is used to indicate whether the system bandwidth of the network device is greater than the channel bandwidth of the terminal. If the system bandwidth of the network device is greater than the channel bandwidth of the terminal, the network device can determine, based on the capability information, that the terminal is allowed to report power margin using the optimized MPR value. Conversely, if the network status information indicates that the system bandwidth of the network device is less than or equal to the channel bandwidth of the terminal, even if the network device receives the capability information of the terminal, it will determine that the terminal is not allowed to report power margin using the optimized MPR value.

[0207] It should be noted that the above embodiments describe how network devices determine whether to allow terminals to report power headroom using optimized MPR values ​​based on different network state information. In many possible implementations, the methods provided in the above embodiments can be used in combination. For example, if network state information indicates two or three network states, the network device can determine whether to allow terminals to report power headroom using optimized MPR values ​​based on capability information if both or all three network states meet the requirements. Conversely, if one of the two or three network states does not meet the requirements, even if the network device receives the terminal's capability information, it will determine that the terminal is not allowed to report power headroom using optimized MPR values.

[0208] In some embodiments, if the network device determines that the terminal is allowed to report power margin using the optimized MPR value, the network device may send first information to the terminal.

[0209] In some embodiments, the first information is used to instruct the network device to allow the terminal to report power margin using an optimized MPR value.

[0210] In some embodiments, the name of the first information is not limited, and it may be, for example, "first instruction", "optimization instruction", etc.

[0211] In some embodiments, the terminal may receive first information sent by the network device, and then report the power margin based on the first information using an optimized MPR value.

[0212] In some embodiments, the first signaling can be used as the carrier of the first information. That is, the network device can send the first signaling to the terminal, the first signaling including the first information, and the terminal can receive the first signaling sent by the network device to receive the first information.

[0213] In some embodiments, the first signaling is used to control and manage resource allocation.

[0214] In some embodiments, the first signaling may be Media Access Control (MAC) Control Element (CE) signaling, or the first signaling may be Downlink Control Information (DCI) indication, but is not limited thereto.

[0215] In some embodiments, the first information is used to instruct the terminal to offset the currently configured radio frequency indicator template outward by a first frequency value. For example, the first information may be used to instruct the terminal to offset the currently configured radio frequency indicator template outward by X MHz.

[0216] In some embodiments, the terminal may determine an optimized MPR value based on a first frequency value and first indication information, and then report the power margin using the optimized MPR value.

[0217] In some embodiments, the first indication information is used to indicate the mapping relationship between the MPR optimization value and the offset of the RF indicator template. Optionally, the first indication information may be a mapping relationship table between the MPR optimization value and the offset of the RF indicator template.

[0218] For example, the mapping relationship between the MPR optimization value indicated by the first indication information and the offset X of the RF indicator template can be shown in Table 1 below:

[0219] Table 1

[0220] In some embodiments, the terminal may determine an MPR optimization value that is mapped to a first frequency value based on the first indication information, and then report the power margin using the optimized MPR value based on the determined MPR optimization value.

[0221] In some embodiments, the first instruction information may be agreed upon by the protocol.

[0222] In some embodiments, the first information is used to instruct the terminal to relax the currently configured radio frequency indicator template by a first decibel. For example, the first information may be used to instruct the terminal to relax the currently configured radio frequency indicator template by Y dB.

[0223] In some embodiments, the terminal can determine the MPR optimization value based on the first decibel and the second indication information, and then report the power margin using the optimized MPR value.

[0224] In some embodiments, the second indication information is used to indicate the mapping relationship between the MPR optimization value and the relaxation value of the RF indicator template. Optionally, the first indication information may be a mapping relationship table between the MPR optimization value and the relaxation value Y of the RF indicator template.

[0225] For example, the mapping relationship between the MPR optimization value indicated by the second indication information and the relaxation value Y of the RF indicator template can be shown in Table 2 below:

[0226] Table 2

[0227] In some embodiments, the terminal may determine an MPR optimization value that is mapped to the first decibel based on the second indication information, and then report the power margin using the optimized MPR value based on the determined MPR optimization value.

[0228] In some embodiments, the second instruction information may be agreed upon in a protocol.

[0229] In some embodiments, when reporting power margin using the optimized MPR value based on the determined optimized MPR value, the optimized MPR value can be determined based on the optimized MPR value and the original MPR value. Then, based on the optimized MPR value, the current maximum transmission power of the terminal can be determined, and the current maximum transmission power of the terminal can be sent to the network device.

[0230] In some embodiments, if the network device determines that the terminal is not allowed to report power margin using the optimized MPR value, then the network device does not need to send the first information to the terminal.

[0231] In some embodiments, if the terminal does not receive information sent by the network device, the terminal may use the original MPR value to report the power margin.

[0232] In some embodiments, if the network device determines that the terminal is not allowed to report power headroom using the optimized MPR value, the network device may send a second message to the terminal, the second message being used to instruct the network device not to allow the terminal to report power headroom using the optimized MPR value.

[0233] In some embodiments, the terminal receives second information sent by the network device, and then, upon receiving second information instructing the network device not to allow the terminal to report power margin using the optimized MPR value, reports power margin using the original MPR value.

[0234] In some embodiments, when a terminal reports its power margin using the original MPR value, it can determine its current maximum transmission power based on the original MPR value and then send the terminal's current maximum transmission power to the network device.

[0235] In some embodiments, the terminals and network devices mentioned in the above embodiments may support enhanced fifth-generation mobile communication technology (5G Advanced, 5G-A, or 5.5G); or, the terminals and network devices may support multiple input multiple output (MIMO) technology; or, the terminals and network devices may support transmit diversity (TxD) technology.

[0236] In other words, the solutions provided in this disclosure can be applied to 5G-A, MIMO and TxD scenarios, but are not limited thereto.

[0237] In some embodiments, terms such as "certain," "preset," "default," "set," "indicated," "a certain," "any," and "first" can be used interchangeably. "Certain A," "preset A," "default A," "set A," "indicated A," "a certain A," "any A," and "first A" can be interpreted as A pre-defined in a protocol or the like, or as A obtained through setting, configuration, or instruction, or as specific A, a certain A, any A, or first A, but are not limited thereto.

[0238] In some embodiments, the determination or judgment can be made by a value represented by 1 bit (0 or 1), or by a true or false value (boolean), or by a comparison of numerical values ​​(e.g., a comparison with a predetermined value), but is not limited thereto.

[0239] In some embodiments, "not expecting to receive" can be interpreted as not receiving on time domain resources and / or frequency domain resources, or as not performing subsequent processing on the data after receiving it; "not expecting to send" can be interpreted as not sending, or as sending but not expecting the receiver to respond to the sent content.

For example, step S3101 may be implemented as a standalone embodiment, step S3102 may be implemented as a standalone embodiment, and step S3101+S3102 may be implemented as a standalone embodiment, but is not limited thereto.

[0242] In some embodiments, step S3102 is optional and may be omitted or replaced in different embodiments.

[0243] In some embodiments, other optional implementations may be described before or after the specification corresponding to FIG3.

[0244] 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 MPR optimization on frequency band nX.

[0245] In some embodiments, after receiving the terminal's capability information, the network side instructs the terminal via MEC CE signaling that the RF indicator template can be offset outward by XMHz under the current configuration or that the RF indicator can be relaxed by YdB under the current configuration. Then, the terminal can report the PHR using the corresponding optimized MPR value according to the network instruction.

[0246] 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.

[0247] In some embodiments, this capability information is reported per band, that is, each frequency band nX corresponds to a capability information.

[0248] In some embodiments, this capability information applies to 5G-A, MIMO, and TxD scenarios.
