[0045] In some embodiments, the configured transmit power for a single carrier may be as follows:

[0046] Allows the terminal to set its configured maximum transmit power P for the carrier of the serving cell in each time slot CMAX,f,c , the configured maximum transmit power P CMAX,f,c Set within the following range:

[0047] P CMAX_L,f,c ≤P CMAX,f,c ≤P CMAX_H,f,c with

[0048] P CMAX_L,f,c =MIN{PEMAX,c –ΔT C,c ,(P PowerClass –ΔP PowerClass )–MAX(MAX(MPR c +ΔMPR c ,

[0049] A-MPR c )+ΔT IB,c +ΔT C,c +ΔT RxSRS ,P-MPR c )}

[0050] P CMAX_H,f,c =MIN{P EMAX,c ,P PowerClass –ΔP PowerClass}

[0051] Among them, P on a single carrier CMAX,f,c It is required that the terminal has a certain degree of flexibility in the specific value selection within an upper and lower limit, and the corresponding parameters can be reported back to the network through PHR;

[0052] Upper limit P CMAX_H,f,c It is the minimum value of the terminal power level limit and network limit, which is used to control interference and meet regulatory requirements;

[0053] Lower limit P CMAX_L,f,c = Based on the upper limit and adding the radiation control factor, various relaxed minimum values ​​are considered to give the terminal various reasonable flexibility;

[0056] Configure the maximum transmit power P CMAX,f,c It is stipulated that the maximum transmit power of the terminal must be within a specified range of upper and lower limits, where the lower limit takes into account a variety of optional relaxations for the terminal compared to the upper limit.

[0057] In addition, there are some other similar concepts used in other scenarios such as carrier aggregation. Similar concepts are sometimes abbreviated as P CMAX .

[0058] In some embodiments, P CMAX,f,c The actual value can be reported based on the accompanying power headroom report (Power Headroom Report, PHR). CMAX,f,c It can be used as the actual maximum transmit power to obtain SD information in the mapping relationship between the maximum transmit power information and the SD information.

[0059] In combination with the accompanying drawings, a sensitivity information reporting method, receiving method, apparatus, terminal and device provided in an embodiment of the present application are described in detail through some embodiments and their application scenarios.

[0060] See also Figure 2 , Figure 2 is a flow chart of a sensitivity information reporting method provided in an embodiment of the present application, such as Figure 2 As shown, the following steps are included:

[0061] Step 201: The terminal sends reporting information to the network side, where the reporting information includes at least one of the following:

[0062] A mapping relationship between maximum transmit power information and SD information, wherein the maximum transmit power information is the maximum transmit power information of the interference signal;

[0063] SD information of the interfered signal.

[0064] In the embodiment of the present application, SD may be referred to as sensitivity rollback, sensitivity reduction, or sensitivity degradation.

[0065] The mapping relationship between the maximum transmit power information and the SD information may include one or more groups of mapping relationships between the maximum transmit power information and the SD information. Through the mapping relationship, the network side can determine the SD information of the terminal based on the maximum transmit power corresponding to the terminal.

[0066] The above-mentioned maximum transmit power information may be information that can represent the maximum transmit power, such as a power value, a level or an index of the maximum transmit power.

[0067] The interference signal is a signal that interferes with a signal of a terminal. For example, in a terminal self-interference scenario, the interference signal is a signal sent or received by the terminal.

[0068] The SD information of the interfered signal may include: actual SD information of the interfered signal, which is not limited to this. For example, in some scenarios, it may also be predicted SD information of the interfered signal.

[0069] In some implementations, the SD information of the interfered signal is the current SD information of the interfered signal of the terminal, that is, the SD information of the interfered signal is dynamically reported.

[0070] In some implementations, the mapping relationship between the above-mentioned maximum transmit power information and the SD information may be dynamically reported by the terminal, may be periodically reported by the terminal, or may be reported to the network side after the terminal accesses the network.

[0071] When the reported information includes the above-mentioned mapping relationship and SD information of the interfered signal, the above-mentioned mapping relationship and SD information of the interfered signal can be sent through different messages, that is, step 201 can send the above-mentioned reporting information through one or more messages, and can be sent at different times.

[0072] In an embodiment of the present application, the above steps can be used to achieve that the SD information obtained by the network side is the SD information corresponding to the maximum transmission power information or the interfered signal. Compared with the static SD information of the terminal, the SD information of the terminal obtained by the network side is more accurate.

[0073] In addition, the higher accuracy of the terminal's SD information obtained by the network side can enable the network side to perform more targeted scheduling, which is beneficial to improving the communication performance of the terminal, such as reducing the interference of the terminal through scheduling to improve the transmission performance of the terminal.

[0074] As an optional implementation manner, the above maximum transmit power information represents a maximum transmit power range.

[0075] In this implementation manner, the mapping relationship between at least one maximum transmit power range and SD information may be implemented through the above mapping relationship, for example, including at least one of the following mapping relationships between the maximum transmit power range and SD information:

[0076] The maximum transmission power of interference is >23dB;

[0077] 23dB>=Interferer Maximum output power>20dB;

[0078] 20dB>=interference maximum transmission power>15dB;

[0079] 15dB>=interference with maximum transmission power.

[0080] Since the maximum transmit power information indicates the maximum transmit power range, this can reduce the overhead of the above mapping relationship.

[0081] In the embodiments of the present application, the maximum transmit power information is not limited to represent the maximum transmit power range. For example, in some special scenarios, the above maximum transmit power information may also represent the commonly used maximum transmit power of the terminal.

[0082] As an optional implementation manner, when the interference signal is distributed on one carrier, the maximum transmit power information is the maximum transmit power of the carrier; or,

[0083] In the case where the interference signal is distributed on multiple carriers, the maximum transmit power information is the maximum transmit power of the multiple carriers combined, or the maximum transmit power information includes the maximum transmit power of each of the multiple carriers.

[0084] The above-mentioned interference signal may be distributed in one carrier or in one frequency band.

[0085] The maximum transmission power of the carrier mentioned above may include: P CMAX,f,c , the P CMAX,f,c The maximum transmit power of the carrier can also be called the maximum transmit power P. CMAX,f,c , or called configuration transmit power P CMAX,f,c .

[0086] The interference signal may be distributed in multiple carriers or in multiple frequency bands.

[0087] The distribution of the interference signal on multiple carriers may be understood as carrier aggregation (CA), and the maximum transmission power of the multiple carriers combined may be the configured maximum transmission power of the CA combination.

[0088] The maximum transmission power of the above-mentioned multiple carriers may include: CMAX ; the P CMAX Configuring the maximum transmit power for multiple carriers is also called configuring the maximum transmit power P. CMAX , or called configuration transmit power P CMAX .

[0089] The maximum transmit power of each of the above-mentioned multiple carriers may include: CMAX,f,c , the P CMAX,f,c The maximum transmission power configured for the carrier, which can also be called the maximum transmission power configured for each of the multiple carriers PCMAX,f,c , or the configured transmit power P of each of the multiple carriers CMAX .

[0090] In the embodiment of the present application, the maximum transmit power information is not limited to the configured P CMAX,f,c or P CMAX , or it can be the maximum transmit power expected by the terminal or agreed upon by the protocol.

[0091] In the above implementation, the mapping relationship between the maximum transmission power of the reported carrier, the maximum transmission power of multiple carriers combined, or the maximum transmission power of each of the multiple carriers and the SD information can be realized, so that the mapping relationship for a single carrier or multiple carriers can be reported to meet the needs of more scenarios and improve compatibility.

[0092] As an optional implementation manner, the mapping relationship includes:

[0093] N groups of mapping relationships between maximum transmit power and SD information, wherein each group of mapping relationships represents a mapping relationship between maximum transmit power information and SD information, or each group of mapping relationships represents a plurality of mapping relationships between maximum transmit power information and SD information, and N is a positive integer greater than 1.

[0094] The value of N may be determined by the protocol, the network configuration, or the terminal.

[0095] Each group of mapping relationships above represents a mapping relationship between maximum transmit power information and SD information, which can be shown in the following table 1

[0096] Table 1:

[0097]

[0098]

[0099] Table 1 can be used to report the mapping relationship between four maximum transmit power ranges and SD information.

[0100] Each group of mapping relationships above represents a mapping relationship between multiple maximum transmit power information and SD information. Each mapping relationship includes multiple maximum transmit power information. The multiple maximum transmit power information and the same SD information correspond to different carriers.

[0101] In this implementation, through the N groups of mapping relationships between the maximum transmission power and the SD information, more SD information can be reported to the network side, so that the network side can obtain more accurate SD information of the terminal.

[0102] Optionally, when the interference signal is distributed on one carrier, each group of mapping relationships represents a mapping relationship between maximum transmit power information and SD information, and the maximum transmit power information is the maximum transmit power of the carrier of the cell where the interference signal is located; or

[0103] In the case where the interference signal is distributed over multiple carriers, each group of mapping relationships represents a mapping relationship between maximum transmit power information and SD information, and the maximum transmit power information is the maximum transmit power of the multiple carriers combined; or, in the case where the interference signal is distributed over multiple carriers, each group of mapping relationships represents a mapping relationship between multiple maximum transmit power information and SD information, and the multiple maximum transmit power information is the maximum transmit power of each carrier in the multiple carriers.

[0104] The maximum transmission power of the carrier of the cell where the interference signal is located can be expressed as P corresponding to the interference signal. CMAX,f,c The maximum transmission power of the above-mentioned multiple carriers can be P of multiple carriers. CMAX The maximum transmit power of each frequency band can be expressed as P CMAX,f,c .

[0105] In this implementation, it is possible to support multiple mapping relationships of maximum transmit power information through reported information, thereby improving the flexibility of reporting, so that the network side can obtain more mapping relationships between maximum transmit power information and SD information, which is conducive to improving the scheduling effect on the network side.

[0106] As an optional implementation manner, the SD information includes:

[0107] SD level, SD value, SD difference relative to the reference value, SD difference relative to the last reported SD value.

[0108] The above-mentioned SD information may be the SD information in the above-mentioned mapping relationship, or may be the SD information of the above-mentioned interfered signal.

[0109] The above-mentioned reference value is a fixed value, which may be a protocol agreement or a network side configuration, etc. The above-mentioned last reported SD value refers to the SD value most recently reported by the terminal to the network side, such as the most recently reported SD value of the interfered signal.

[0110] In this implementation, it is possible to support reporting of multiple SD information, and the reporting overhead can be saved by using the SD level, the SD difference relative to the reference value, or the SD difference relative to the last reported SD value.

[0111] As an optional implementation manner, the SD information in the mapping relationship includes: MSD information.

[0112] In this implementation, a mapping relationship between the maximum transmit power information and the MSD information can be realized, wherein the MSD information may include: MSD level, MSD value, MSD difference relative to the reference value, and MSD difference relative to the last reported MSD value.

[0113] In the embodiment of the present application, the SD information in the above mapping relationship is not limited to MSD information, and may be an SD value.

[0114] As an optional implementation, the SD information is SD information with frequency band as granularity (per band), or SD information with carrier as granularity (per CC), or SD information with carrier unit as granularity, or the SD information is SD information with frequency band in a frequency band combination as granularity (per band per band combination).

[0115] The SD information with the frequency band in the frequency band combination as the granularity can be understood as the SD information of the same frequency band in different frequency band combinations is independent, but can be the same or different.

[0116] In this implementation, reporting of SD information with different granularities can be achieved to improve the accuracy of SD information reporting.

[0117] As an optional implementation manner, the reporting information further includes at least one of the following items corresponding to the SD information:

[0118] Interferer band, victim band, SD type, order, power class, and the area where the interfering signal is located.

[0119] The above SD types may include harmonic, harmonic mixing, intermodulation (IMD) or cross band isolation interference or other SD types;

[0120] Among them, harmonic refers to the SD caused by the harmonic of interference falling on the interfered signal; harmonic mixing refers to the SD caused by the mixing of the transmitted signal on the high frequency band and the harmonic signal on the low frequency band to the low frequency band; intermodulation refers to the SD caused by the intermodulation product of two interfering signals acting on the interfered signal; cross-band isolation refers to the SD caused by the interference signal directly interfering with the interfered signal through leakage.

[0121] The above order may be the order of interference.

[0122] In this implementation, more restriction conditions may be added to the SD information in the mapping relationship or the SD information of the interfered signal to improve the accuracy of the SD information.

[0123] As an optional implementation manner, the reporting information is sent through at least one of the following:

[0124] Radio Resource control (RRC signaling), Media Access Control-Control Element (MAC-CE), PHR.

[0125] The sending of the above-mentioned reporting information through the above-mentioned at least one item can be understood as the above-mentioned reporting information being carried in the above-mentioned at least one item.

[0126] In this implementation, the reporting information can be sent in multiple messages to improve the flexibility of sending the reporting information. In addition, sending through PHR can avoid adding additional messages, thereby saving transmission overhead.

[0127] As an optional implementation, the above method further includes:

[0128] The terminal reports the actual maximum transmit power information of the interference signal to the network side, and the actual maximum transmit power information is used to obtain SD information in the mapping relationship between the maximum transmit power information and the SD information.

[0129] The above-mentioned actual maximum transmit power information may be the maximum transmit power information when the terminal sends an interference signal, such as P CMAX,f,c or P CMAX ; and the above-mentioned actual maximum transmit power information can be sent dynamically. If the maximum transmit power information changes, the changed maximum transmit power information is reported.

[0130] After receiving the above-mentioned actual maximum transmit power information, the network side can determine or update the SD information of the terminal based on the actual maximum transmit power information and the above-mentioned mapping relationship, thereby obtaining the current SD information of the terminal, and then perform corresponding scheduling based on the SD information to improve the communication performance of the terminal.

[0131] In an embodiment of the present application, the terminal sends reporting information to the network side, and the reporting information includes at least one of the following: a mapping relationship between maximum transmit power information and SD information, wherein the maximum transmit power information is the maximum transmit power information of the interference signal; and the SD information of the interfered signal. In this way, the SD information obtained by the network side is the SD information corresponding to the maximum transmit power information or the interfered signal, and the SD information of the terminal obtained by the network side is more accurate than the static SD information of the terminal.

[0158] The network side device determines or updates the SD information of the terminal based on the actual maximum transmit power information and the mapping relationship.

[0159] It should be noted that this embodiment is Figure 2 The implementation of the corresponding network side device in the embodiment shown in the figure can be found in the specific implementation of Figure 2 To avoid repeated description, the related description of the embodiment shown in the present invention will not be repeated in detail.

[0160] The method provided in the embodiments of the present application is illustrated below by means of multiple embodiments:

[0161] Embodiment 1:

[0162] In this embodiment, the terminal reports the corresponding maximum sensitivity reduction according to the change of its own maximum transmit power, which is as follows:

[0163] Depending on its own implementation, the terminal can define a capability to indicate that the terminal has the following capabilities:

[0164] In case of different maximum transmit powers of interference signals, multiple groups of different MSD values ​​can be reported in advance, corresponding to different maximum transmit power limits of the current interference frequency band or carrier of the terminal. The power of the current interference frequency band or carrier can be the corresponding configured transmit power P cmax,f,c or P cmax , where the transmission power P cmax,f,c and P cmax Please refer to the relevant definitions in the protocol and will not be elaborated here.

[0165] A specific example is as follows: for a specific interference scenario, the terminal can report the following maximum interference transmission power (for example, P cmax,f,c Or other configuration transmission power P cmax The corresponding relationship between the relevant parameters) and the interfered signal MSD is shown in Table 1 above. Table 1 above shows an example of a dynamic sensitivity reporting table corresponding to a certain interference scenario, specifically corresponding to different interference powers.

[0166] For the case where the interference frequency band is a single carrier, in the above example, the maximum interference output power can be P cmax,f,c, or other similar power values. This table is reported to the network after the terminal accesses the network, so that the network can understand the different sensitivity reductions caused to the interfered signal by the terminal's maximum interference power in different ranges. cmax,f,c It can be reported through MAC-CE.

[0167] For the case where the interference frequency band is a frequency band combination composed of multiple carriers, the maximum interference output power in the example above can be the total CA configuration maximum transmit power P of the interference carrier combination. cmax This parameter can also be the maximum output power P configured on each of the two carriers. cmax,f,c The combination of parameters can also be other similar (for example: based on frequency band) power values. cmax You can also use P cmax,f,c The reporting mechanism may be, for example, reporting through MAC-CE.

[0168] The victim MSD classes or values ​​refer to the reduction in sensitivity caused by the interference signal. Lower MSD capability classes may be used, or any new MSD values ​​may be defined.

[0169] In the above example, for a certain interference scenario, under the influence of specific resource configuration and other factors, the maximum power of the interference signal (for example, P cmax )>=23dBm, the corresponding MSD is level IV, and the MSD in the corresponding LowerMSD table is <=9dB, which means that the corresponding SD is 9dB in this case. 9dB can also be reported directly, or other values ​​that meet the terminal implementation, or the difference relative to a certain value.

[0170] When certain resources change or power backoff changes caused by other reasons further reduce the maximum terminal interference power to between 23 and 20dBm, the corresponding MSD value of the interfered signal is level III or 6dB, or other values ​​or differences relative to a certain value can be directly defined.

[0171] The length of the mapping table here (ie, the number of power indexes) can be more values, such as 2 / 4 / 8 / etc.

[0172] The above mapping reporting information may be reported via terminal RRC signaling.

[0173] like Figure 4 As shown:

[0174] Step 401: The terminal reports the mapping relationship between the maximum interference transmission power and the MSD to the network side;

[0175] Step 402: The terminal reports the actual maximum transmit power to the network side;

[0176] Step 404: The network side determines the MSD of the terminal based on the actual maximum transmit power and the mapping relationship.

[0177] If the network side has the above table information, along with the terminal P cmax The network can determine the corresponding P cmax MSD, so that the network can grasp the different MSD performance of the interfered signal of the terminal under more interference signal maximum power constraints.

[0178] Among them, the MSD in this embodiment can be defined based on the frequency band, that is, defined with the frequency band as the granularity (per band), or can be defined based on the carrier, that is, defined with the carrier as the granularity (per CC), or can be defined based on the frequency band in the frequency band combination, that is, defined with the frequency band in the frequency band combination as the granularity (per band per band combination).

[0179] Among them, the power in this embodiment can be defined based on the frequency band, that is, defined with the frequency band as the granularity (per band), or it can be defined based on the carrier, that is, defined with the carrier as the granularity (per CC), or it can be defined based on the frequency band in the frequency band combination, that is, defined with the frequency band in the frequency band combination as the granularity (per band per band combination).

[0180] The above-mentioned specific interference scenario refers to more restrictive conditions. For example, the restriction information corresponding to the MSD also includes some or all of the following items:

[0181] Interferer band;

[0182] Victim band;

[0183] MSD types and corresponding orders, where MSD types may include harmonic, harmonic mixing, intermodulation (IMD) or cross band isolation interference or other MSD types;

[0184] Power class.

[0185] In some implementations, other influencing factors not mentioned in the above table, such as regional influence, are assumed to use the region with the greatest interference.

[0186] In this embodiment, the above-mentioned specific interference scenario may be a terminal self-interference scenario, which is not specifically limited.

[0187] Embodiment 2:

[0188] In this embodiment, the terminal reports the actual sensitivity reduction according to its actual transmit power, which specifically includes the following:

[0189] For a specific interference scenario, the terminal dynamically reports the actual SD data of the interfered signal according to its actual interference situation (eg, the actual current transmit power of the interfering signal or other resource scheduling situation).

[0190] This actual SD reporting can be reported using the terminal MAC-CE, such as the MAC CE of the PHR.

[0191] In this embodiment, there is no need to design and define the corresponding relationship between power and SD in advance, and there is no need to report these relationships, all of which are implemented by the terminal.

[0192] The reported SD value may be based on the granularity of the lower MSD report, or may be directly a new granularity, or a new set of similar mapping tables may be defined.

[0193] The SD here can be defined based on the frequency band, that is, defined with the frequency band as the granularity (per band), or based on the carrier definition, that is, defined with the carrier as the granularity (per CC), or defined based on the frequency band in the frequency band combination, that is, defined with the frequency band in the frequency band combination as the granularity (per band per band combination).

[0194] The above-mentioned specific interference scenario refers to more restrictive conditions. For example, the restriction information corresponding to the MSD also includes some or all of the following items:

[0195] Interferer band;

[0196] Victim band;

[0197] MSD types and corresponding orders, where MSD types may include harmonic, harmonic mixing, intermodulation (IMD) or cross band isolation interference or other MSD types;

[0198] Power class.

[0199] It should be noted that, in this embodiment, the above-mentioned specific interference scenario may be a terminal self-interference scenario, which is not specifically limited.

[0200] In the embodiment of the present application, one mechanism is that the terminal reports the corresponding maximum sensitivity reduction according to the change of its own maximum transmit power; specifically, in a specific interference scenario, the terminal reports its corresponding maximum sensitivity fallback at different maximum transmit powers, using the existing configuration transmit power P cmax Power reporting mechanism, the network can determine the maximum sensitivity fallback corresponding to the current maximum transmit power of the terminal;

[0201] Another mechanism is that the terminal reports the actual sensitivity reduction according to its actual transmit power.

[0202] In the embodiments of the present application, the network can more accurately grasp the sensitivity backoff actually required by the current terminal and achieve more accurate scheduling.

[0203] The sensitivity information reporting method provided in the embodiment of the present application can be executed by a sensitivity information reporting device.
