The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this disclosure, and should not be construed as limiting this disclosure.

[0057] like Figure 1 As shown, the communication method provided in this embodiment can be applied to a wireless communication system 100, which may include a user equipment 101 and a network device 102. The user equipment 101 is configured to support carrier aggregation and can be connected to multiple carrier units of the network device 102, including a primary carrier unit and one or more secondary carrier units.

[0058] The network device 102 may include access network equipment, ground stations, earth stations or gateways in terrestrial networks (TN), or satellite access networks (SAN) in non-terrestrial networks (NTN).

[0059] Access network equipment refers to equipment that provides network access functionality, such as radio access network (RAN) base stations. Network equipment 102 may specifically include a base station (BS), or a base station and radio resource management equipment for controlling the base station. Network equipment 102 may also include relay stations (relay equipment), access points, and base stations in future 5G networks, future PLMN networks, or NR base stations. Network equipment 102 can be a wearable device or an in-vehicle device. Network equipment 102 can also be a communication chip with a communication module.

[0060] It should be understood that the wireless communication system 100 described above is applicable to both low-frequency and high-frequency scenarios. Application scenarios for the wireless communication system 100 include, but are not limited to, long-term evolution (LTE) systems, LTE frequency division duplex (FDD) systems, LTE time division duplex (TDD) systems, worldwide interoperability for microwave access (WiMAX) communication systems, cloud radio access network (CRAN) systems, future 5th-generation (5G) systems, new radio (NR) communication systems, or future evolved public land mobile network (PLMN) systems.

[0061] The user equipment 101 shown above can be a terminal, access terminal, terminal unit, terminal station, mobile station (MS), remote station, remote terminal, mobile terminal, wireless communication device, terminal agent, or terminal equipment, etc. This user equipment 101 may have wireless transceiver capabilities, enabling it to communicate (e.g., wirelessly) with one or more network devices in one or more communication systems and receive network services provided by the network devices.

[0063] As shown in Table 1, the MPR generally will not exceed the values ​​defined in Table 1. The MPR is related to the modulation waveform, order, and resource location. The MPR corresponding to different modulation waveforms, orders, and resource locations can be pre-stored in the user equipment 101.

[0064] Table 1

[0065]

[0066] Among them, the edge resource block (Edge RB) refers to the RB located on both sides of the frequency band boundary, and the outer resource block (Outer RB) is located between the inner resource block (Inner RB) and the edge RB.

[0067] Out-of-band radiation requirements are generally based on regulatory requirements, and are designed to prevent user equipment 101 from causing excessive interference to other equipment. In-band radiation requirements, on the other hand, mainly depend on the Error Vector Magnitude (EVM) requirement corresponding to the modulation method. Under certain environmental conditions, the applicability of MPR may differ.

[0068] This disclosure provides a communication method in its embodiments. (Refer to...) Figure 2 As shown, Figure 2 This is an interactive flowchart illustrating a communication method according to an exemplary embodiment, such as... Figure 2 As shown, the method includes steps S201 to S202, specifically:

[0069] In step S201, network device 102 sends first information to user equipment 101, the first information being used to indicate the determination method of maximum power back-off (MPR) under the first condition.

[0070] In some possible implementations, such as Figure 1 In the communication system shown, network device 102 can be either a ground base station or a SAN.

[0071] In some possible implementations, the first condition may be a condition associated with geographical features, location, or regulatory requirements. For example, the first condition may refer to an environmental condition that minimizes network access devices and eliminates the need to consider interference with other devices, i.e., an environmental condition that does not require consideration of out-of-band radiation requirements. Environments that meet the first condition may include sparsely populated environments such as the high seas, deserts, mountains, and remote mountainous areas.

[0072] In some possible implementations, network device 102 may determine whether it meets the first condition based on the current environment or the geographical location, geographical features or regulatory requirements of the deployment site.

[0073] In some possible implementations, the MPR under the first condition may be less than the value defined by the relevant protocols in Table 1; for example, the MPR may be 0. It is understood that under the first condition, when accessing network device 102, out-of-band radiation requirements may not need to be met, thus reducing power backoff.

[0074] In some possible implementations, network device 102 may send the indication information via Radio Resource Control (RRC). Alternatively, it may send the indication information via Downlink Control Information (DCI).

[0075] In some possible implementations, the first information may indicate a variety of methods for determining the MPR, such as methods for determining the MPR under first conditions or methods for determining the MPR under normal conditions.

[0076] Understandably, this determination method refers to how to calculate or determine the MPR, or the applicable circumstances for the MPR. For example, the determination method includes determining the MPR based on the relevant agreements in Table 1.

[0077] In step S202, the user equipment 101 determines the first maximum power back-off (MPR) based on the first information, wherein the first information is used to indicate the method of determining the MPR under the first condition.

[0078] In some possible implementations, user equipment 101 may select a more suitable first MPR based on the usage of the MPR notified by network equipment 102.

[0079] For example, under the first condition, user equipment 101 can select a smaller MPR compared to the relevant protocol, such as the first MPR being 0.

[0080] In this embodiment of the present disclosure, network device 102 may send first information to user equipment 101 to indicate the method of determining MPR under the first condition, so that user equipment 101 can determine a more reasonable MPR under the first condition, thereby reducing power back-off under the first condition and improving uplink coverage.

[0081] This disclosure provides a communication method in its embodiments. (Refer to...) Figure 3 As shown, Figure 3 This is an interactive flowchart illustrating a communication method according to an exemplary embodiment, such as... Figure 3 As shown, the method includes steps S301 to S303, specifically:

[0082] In step S301, user equipment 101 sends request information to network device 102 based on first information and second information. The request information is used to request the first MPR corresponding to the first condition.

[0083] In some possible implementations, the first information can be defined by a protocol or configured by network device 102 to user equipment 101.

[0084] In some possible implementations, the second information includes the location information of the user equipment 101. Alternatively, the second information may be information associated with the location of the user equipment 101. The location information of the user equipment 101 can characterize the geographical location or environment of the user equipment 101, and this location information includes, but is not limited to, latitude and longitude, absolute coordinates in a known reference frame, relative coordinates relative to a known reference object, or angular distance relative to a known reference object.

[0085] In one example, user equipment 101 can locate itself and obtain location information through its own sensors.

[0086] In another example, user equipment 101 can obtain location information provided by network device 102 based on communication with different network devices 102.

[0087] In some possible implementations, the user equipment 101 determines whether the geographical location or environment meets the first condition based on the second information, such as location information. When the first condition is met, the user equipment 101 determines a smaller MPR than that in the relevant protocol in the first information, namely the first MPR.

[0088] In some possible implementations, after user equipment 101 determines the first MPR on its own, it needs to send a request message to network equipment 102 to apply for the application of the first MPR.

[0089] In step S302, network device 102 receives the request information and sends corresponding feedback information to user device 101. The feedback information is used to allow user device 101 to fulfill its request.

[0090] In some possible implementations, after receiving the request information from the user equipment 101, the network device 102 can process the request from the user equipment 101.

[0091] Alternatively, network device 102 can verify the location of user equipment 101 and verify whether the first MPR requested by user equipment 101 conforms to the corresponding determination method. After successful verification, it sends an approval feedback message.

[0092] In step S303, the user equipment 101 determines the first MPR upon receiving the feedback information.

[0093] In some possible implementations, the user equipment 101 can only apply the first MPR after receiving the feedback information.

[0094] In some possible implementations, if user equipment 101 does not receive the feedback information within a set time period, or receives a rejection information from network device 102, then user equipment 101 cannot apply the first MPR and must use the MPR defined in the relevant protocol.

[0095] In this embodiment of the disclosure, user equipment 101 can determine the applicable MPR according to its own environment and apply to network device 102. After obtaining permission from network device 102, user equipment 101 applies the requested MPR in order to reduce power backoff and enhance uplink coverage.

[0096] This disclosure provides a communication method, which is executed by user equipment 101. (Refer to...) Figure 4 As shown, Figure 4 This is a communication method illustrated according to an exemplary embodiment, such as... Figure 4 As shown, the method includes step S401, specifically:

[0097] In step S401, the user equipment 101 determines the first maximum power back-off (MPR) based on the first information, wherein the first information is used to indicate the method of determining the MPR under the first condition.

[0098] In some possible implementations, the first condition may be a condition associated with geographical features, location, or regulatory requirements. For example, the first condition may refer to an environmental condition that minimizes network access devices and eliminates the need to consider interference with other devices, i.e., an environmental condition that does not require consideration of out-of-band radiation requirements. Environments that meet the first condition may include sparsely populated environments such as the high seas, deserts, mountains, and remote mountainous areas.

[0099] In some possible implementations, the MPR under the first condition may be less than the value defined by the relevant protocols in Table 1; for example, the MPR may be 0. It is understood that when accessing network device 102 under the first condition, out-of-band radiation requirements need not be met, thus reducing power backoff.

[0100] In some possible implementations, in a multi-carrier scenario, each of the multiple carriers is configured with the first information, or each of the multiple frequency bands is configured with the first information.

[0101] The multi-carrier scenario can be based on carrier aggregation (CA), dual connectivity (DC), or multi-carrier technology based on multi-access system dual connectivity (MRDC). MRDC can be Evolved Universal Terrestrial Radio Access Network (E-UTRAN) New Radio Dual Connectivity (EN-DC) or New Radio and 4G Radio Access Network (NR eNB Dual Connection (NE-DC), etc.

[0102] In this embodiment of the disclosure, according to the indication of the first information, the user equipment 101 can determine a more reasonable MPR under the first condition in order to reduce the power back-off under the first condition, thereby helping to enhance uplink coverage.

[0103] This disclosure provides a communication method, which is executed by user equipment 101. (Refer to...) Figure 5 As shown, Figure 5 This is a communication method illustrated according to an exemplary embodiment, such as... Figure 5 As shown, the method includes steps S501 to S502, specifically:

[0104] In step S501, user equipment 101 receives first information sent by network device 102, the first information being used to indicate the determination method of maximum power back-off (MPR) under the first condition.

[0105] In some possible implementations, network device 102 may send the first information to user equipment 101 upon a first condition. Alternatively, network device 102 may send the first information upon request from user equipment 101.

[0106] In some possible implementations, user equipment 101 may receive indication information sent by network device 102 via RRC signaling or DCI.

[0107] In some possible implementations, if the first information sent by the network device 102 is not received, the user equipment 101 determines the MPR in accordance with the relevant protocol.

[0108] In some possible implementations, in a multi-carrier scenario, each of the multiple carriers is configured with the first information, or each of the multiple frequency bands is configured with the first information.

[0109] In one example, when configuring the first information corresponding to each carrier, the network device 102 sends the first information in a carrier-by-carrier (per CC) manner.

[0110] In another example, when configuring the corresponding first information for each frequency band, the network device 102 sends the first information in a per-band manner.

[0111] In step S502, the user equipment 101 determines the first maximum power back-off (MPR) based on the first information, wherein the first information is used to indicate the method of determining the MPR under the first condition.

[0112] The implementation method of step S502 can be found in step S401, and will not be repeated here.

[0113] In this embodiment of the disclosure, the user equipment 101 receives first information from the network device 102 to learn the determination method of the maximum power back-off (MPR) under the first condition.

[0114] This disclosure provides a communication method, which is executed by user equipment 101. The method includes steps S401-1 and S401-2, specifically:

[0115] Step S401-1: User equipment 101 sends request information to network device 102 based on first information and second information. The request information is used to request the first MPR corresponding to the first condition.

[0116] In some possible implementations, the first information can be defined by a protocol or configured by network device 102 to user equipment 101.

[0117] In some possible implementations, the second information includes the location information of the user equipment 101. Alternatively, the second information may be information associated with the location of the user equipment 101. The location information of the user equipment 101 can characterize the geographical location or environment of the user equipment 101, and this location information includes, but is not limited to, latitude and longitude, absolute coordinates in a known reference frame, relative coordinates relative to a known reference object, or angular distance relative to a known reference object.

[0118] In some possible implementations, the user equipment 101 determines, based on second information such as location information, that the geographical location or environment meets a first condition. When the first condition is met, the user equipment 101 determines a smaller MPR than that in the relevant protocol in the first information, namely a first MPR.

[0119] In some possible implementations, after user equipment 101 determines the first MPR on its own, it needs to send a request message to network equipment 102 to apply for the application of the first MPR.

[0120] Step S401-2: Upon receiving feedback information from the network device, the user equipment 101 determines the first MPR, wherein the feedback information is used to allow the user equipment 101's request.

[0121] In some possible implementations, user equipment 101 can only determine to adopt the requested first MPR upon receiving the feedback information. If the feedback information is not received, or if a rejection information is received, user equipment 101 must adopt the MPR defined in the relevant protocol.

[0122] In this embodiment of the disclosure, user equipment 101 can determine the applicable MPR according to its own environment and apply to network device 102. After obtaining permission from network device 102, user equipment 101 applies the requested MPR in order to reduce power backoff and enhance uplink coverage.

[0123] This disclosure provides a communication method, which is executed by a user equipment 101. The method includes step S401, specifically:

[0124] In step S401, the user equipment 101 determines the first maximum power back-off (MPR) based on the first information, wherein the first information is used to indicate the method of determining the MPR under the first condition.

[0125] The first information includes an information field for indicating the determination method.

[0126] In some possible implementations, the first information may be sent by network device 102.

[0127] In some possible implementations, user equipment 101 may also determine the applicable first MPR based on location information and should use the first MPR when requesting passage from network device 102.

[0128] In some possible implementations, the information field may contain one or more bits, and different bit values ​​in the information field correspond to different determination methods.

[0129] In one example, we will illustrate this using an information field containing 2 bits. Referring to Table 2, when the 2 bits are 00, the corresponding determination method is the first method; when the 2 bits are 01, the corresponding determination method is the second method; and when the 2 bits are 10, the corresponding determination method is the third method.

[0130] In the first method, the determination of MPR and additional power back-off A-MPR are performed according to the relevant protocols shown in Table 1.

[0131] In the second method, there is no requirement for out-of-band radiation, so an MPR without out-of-band radiation requirements can be selected. In this second method, A-MPR is 0.

[0132] In the third method, MPR is 0, and A-MPR is also 0.

[0133] Table 2

[0134] 2-bit value Determination method 00 First method 01 Second method 10 Third method 11 Reserved bits

[0135] It is worth noting that, under the first condition, the second or third method may be used to determine the MPR.

[0136] In some possible implementations, step S401 in this embodiment may include the following step S401', specifically:

[0137] In step S401', the user equipment 101 determines the corresponding determination method based on the bit value of the information field, and determines the first MPR based on the determination method.

[0138] For example, when the bit value in the information field is 00, user equipment 101 determines the first MPR according to a first method. When the bit value in the information field is 01, user equipment 101 determines the first MPR according to a second method. When the bit value in the information field is 10, user equipment 101 determines the first MPR according to a third method.

[0139] In some possible implementations, there is no out-of-band radiation requirement in the second approach. The MPR of user equipment 101 depends on the in-band radiation requirement, that is, on the EVM requirement corresponding to different modulation schemes. In this scenario, the MPR does not need to distinguish the RB position.

[0140] In one example, in the second approach, user equipment 101 can determine the MPR based on UE capabilities or implementation. For example, in this example, user equipment 101 determines the MPR0 under the current transmission condition (such as modulation method) according to the relevant protocol shown in Table 1. Then: first MPR = (MPR0 - offset value), where the offset value is determined by user equipment 101 or predefined.

[0141] In another example, according to the second approach, the MPR under different modulation schemes can be determined by defining the protocol or introducing the mapping relationship shown in Table 3. Referring to Table 3, the corresponding MPR can be determined based on the modulation scheme for Edge RB, Outer RB, and Inner RB.

[0142] In this example, a smaller MPR can be determined compared to the related protocols in Table 1, especially for Edge RB and Outer RB, which will effectively reduce the MPR and thus ensure uplink transmit power.

[0146] In step S601, the user equipment 101 determines the first maximum power back-off (MPR) based on the first information, wherein the first information is used to indicate the method of determining the MPR under the first condition.

[0147] The implementation of step S601 can be found in the implementation of step S401 described above, and will not be repeated here.

[0148] In step S602, user equipment 101 determines the maximum allowed configuration power P of the terminal based on the first MPR. CMAX .

[0150] MPR can be used to determine the lower limit value P. CMAX_L,f,c ,For example:

[0151] P CMAX_L,f,c =MIN{P EMAX,c –ΔT C,c ,(P PowerClass –ΔP PowerClass )–MAX(MAX(MPR c +ΔMPR c A-MPR c )+ΔT IB,c +ΔT C,c +ΔT RxSRS P-MPR c )};

[0152] P CMAX_H,f,c =MIN{P EMAX,c ,P PowerClass –ΔP PowerClass};

[0153] Among them, P EMAX,c The maximum transmit power configured for network device 102, P PowerClass For the maximum transmit power capability of user equipment 101, MPR c That is MPR, A-MPR c That is A-MPR, ΔT IB,c For additional power offset, P-MPR c To meet the maximum power backoff value when the electromagnetic radiation level of the human body absorption terminal meets the standard, ΔT C,c ΔP PowerClass and ΔT RxSRS These are constants. It is understandable that the meaning of the above parameters can be further explained by referring to the relevant protocol specifications.

[0154] In one example, if user equipment 101 learns from the first information that the bit value of the information field is 10, this corresponds to the third method. User equipment 101 can determine the first MPR according to the third method, that is, at this time the first MPR and A-MPR are 0, then the P determined above... CMAX_L,f,c The parameter "MAX(MAX(MPR)" in the formula c +ΔMPR c A-MPR c )" = 0

[0155] Therefore, in this embodiment of the disclosure, by reducing MPR, P can be improved. CMAX The lower limit, that is, it can increase PCMAX This can significantly increase the uplink transmit power limit of the terminal and effectively enhance uplink coverage.

[0157] In step S701, network device 102 sends first information to user equipment 101, the first information being used to indicate the determination method of maximum power back-off (MPR) under the first condition.

[0158] In some possible implementations, such as Figure 1 In the communication system shown, network device 102 can be either a ground base station or a SAN.

[0159] In some possible implementations, the first condition may be a condition associated with geographical features, location, or regulatory requirements. For example, the first condition may refer to an environmental condition that minimizes network access devices and eliminates the need to consider interference with other devices, i.e., an environmental condition that does not require consideration of out-of-band radiation requirements. Environments that meet the first condition may include sparsely populated environments such as the high seas, deserts, mountains, and remote mountainous areas.

[0160] In some possible implementations, network device 102 may determine whether the current environment meets the first condition based on the current environment, such as the geographical location, geographical features, or regulatory requirements of the deployment site.

[0161] In some possible implementations, network device 102 may send indication information to user equipment 101 via RRC signaling or DCI.

[0162] In some possible implementations, the first information includes an information field for indicating the determination method.

[0163] For example, as shown in Table 2, different bit values ​​in the information field can be used to indicate the determination method.

[0164] In some possible implementations, in a multi-carrier scenario, each of the multiple carriers is configured with the first information, or each of the multiple frequency bands is configured with the first information.

[0165] In one example, when configuring the first information corresponding to each carrier, the network device 102 sends the first information in a carrier-by-carrier (per CC) manner.

[0166] In another example, when configuring the corresponding first information for each frequency band, the network device 102 sends the first information in a per-band manner.

[0167] It is understood that the implementation methods of this disclosure can also be found in other sources. Figures 2 to 6 The descriptions of the corresponding embodiments are not exhaustive here.

[0168] In this embodiment of the present disclosure, network device 102 may send first information to user equipment 101 to indicate the method of determining MPR under the first condition, so that user equipment 101 can determine a more reasonable MPR under the first condition, thereby reducing power back-off under the first condition and improving uplink coverage.

[0169] This disclosure provides a communication method, which is executed by a network device 102. The method may include steps S701 to S703, specifically:

[0170] In step S701, network device 102 sends first information to user equipment 101, the first information being used to indicate the determination method of maximum power back-off (MPR) under the first condition.

[0171] In step S702, network device 102 receives request information sent by user equipment 101. The request information is used to request the first MPR corresponding to the first condition.

[0172] In some possible implementations, user equipment 101 sends request information when a first condition is met, based on first information and second information.

[0173] In some possible implementations, the second information includes the location information of the user equipment 101. Alternatively, the second information may be information associated with the location of the user equipment 101.

[0174] In some possible implementations, after receiving the request information from user equipment 101, network device 102 can process the request from user equipment 101. Alternatively, network device 102 can verify the location of user equipment 101 and verify whether the first MPR requested by user equipment 101 conforms to the corresponding determination method. After successful verification, it sends an approval feedback message.

[0175] In step S703, network device 102 sends feedback information corresponding to the request information to user device 101. The feedback information is used to allow the user device's request.

[0176] In some possible implementations, the user equipment 101 can only apply the first MPR after receiving the feedback information.

[0177] In some possible implementations, if the network device 102 does not send the feedback information or sends a rejection information within a set time period, the user equipment 101 cannot apply the first MPR and must use the MPR defined in the relevant protocol.

[0178] It is understood that the implementation methods of this disclosure can also be found in other sources. Figures 2 to 6 The descriptions of the corresponding embodiments are not exhaustive here.
