Technical Field

[0002] Maximum Sensitivity Degradation (MSD) is the maximum sensitivity degradation or reference sensitivity exceptions for Carrier Aggregation (CA) or Dual Connectivity (DC) specified in the protocol.

For some band combinations, the MSD value may be as high as 30dB. MSD is set for a specific uplink (UL) or downlink (DL) bandwidth and uplink power level. When the terminal has a better MSD than defined in the specification, if the terminal reports a lower MSD, it helps the network schedule the terminal.

[0053] For ease of understanding, some contents involved in the embodiments of the present application are described below:

[0054] 1. About MSD.

[0055] MSD is also called reference sensitivity exceptions.

[0056] The product of an RF signal entering a nonlinear device is generally described by a polynomial:

[0057] y=f(v)=a0+a1v+a2v 2 +a3v 3 +a4v 4 +a5v 5 +…

[0058] Among them, v is the input signal and y is the output signal.

[0059] Harmonic interference mainly refers to the sensitivity interference caused by the harmonics of transmission (Transmit, TX), such as LTE's TX harmonics interfering with NR's receiving sensitivity, or NR's TX harmonics interfering with LTE's sensitivity.

[0060] like Figure 2As shown in the figure, when the input frequency is a single frequency signal cos2πf0t with a frequency of f0, the output signal y contains high-order harmonic components such as 2f0 and 3f0. If the harmonic falls into another receiving frequency band, it will cause harmonic interference, which often occurs in scenarios where low-frequency transmission and high-frequency reception are performed simultaneously. Typical scenarios include LTE and 5G dual connectivity (E-UTRAN NewRadio Dual Connectivity, EN-DC) B3+N78, B8+N41, etc.:

[0061] The second harmonic of B3 TX (frequency is 1710MHz~1785MHz) interferes with N78 RX (frequency is 3300MHz~3800MHz);

[0062] The third harmonic of B8 TX (frequency is 880MHz~915MHz) interferes with N41 RX (frequency is 2496MHz~2690MHz).

[0063] Intermodulation distortion interference mainly refers to the sensitivity interference caused by the frequency migration falling into the receiving band after the two TX frequencies (or their multiples) are multiplied. For example, after the TX frequencies of LTE B3 and N78 are multiplied, they fall into the LTE B3 RX band, causing the LTE B3 receiving sensitivity to decrease. Figure 2 shown.

[0064] When the input signal contains multiple frequency components, the output includes intermodulation products of various orders of these frequency components. Taking the input of two frequency components cos2πf1t and cos2πf2t as an example, the output products will include second-order intermodulation (f1±f2), third-order intermodulation (2f1±f2, f1±2f2), etc. If the intermodulation products fall into the receiving frequency band, intermodulation interference will be caused. Among intermodulation distortion, the second-order and third-order distortion amplitudes are the largest. The higher the order, the smaller the distortion amplitude. Generally speaking, the amplitude of intermodulation distortion above the third order is small and the impact brought by it can be ignored in most scenarios. Typical interference scenarios include ENDC B3+N78:

[0065] The second-order intermodulation product (fn78-fB3) of B3 TX (frequency is 1710MHz~1785MHz) and N78 TX (frequency is 3300MHz~3800MHz) interferes with B3 RX (frequency is 1805MHz~1880MHz).

[0066] Intermodulation distortion interference mainly refers to the sensitivity interference caused by the frequency migration falling into the receiving band after the two TX frequencies (or their multiples) are multiplied. For example, after the TX frequencies of LTE B3 and N78 are multiplied, they fall into the LTE B3 RX band, causing the LTE B3 receiving sensitivity to decrease. Figure 3 shown.

[0067] When the input signal contains multiple frequency components, the output includes intermodulation products of various orders of these frequency components. Taking the input of two frequency components cos2πf1t and cos2πf2t as an example, the output products will include second-order intermodulation (f1±f2), third-order intermodulation (2f1±f2, f1±2f2), etc. If the intermodulation products fall into the receiving frequency band, intermodulation interference will be caused. Among intermodulation distortion, the second-order and third-order distortion amplitudes are the largest. The higher the order, the smaller the distortion amplitude. Generally speaking, the amplitude of intermodulation distortion above the third order is small and the impact brought by it can be ignored in most scenarios. Typical interference scenarios include ENDC B3+N78:

[0068] The second-order intermodulation product (fn78-fB3) of B3 TX (frequency is 1710MHz~1785MHz) and N78 TX (frequency is 3300MHz~3800MHz) interferes with B3 RX (frequency is 1805MHz~1880MHz).

[0069] 2. Lower MSD.

[0070] Signaling design for lower MSD capabilities needs to consider the following information:

[0071] Victim band (or victim band);

[0072] MSD type (harmonic; harmonic mixture; cross-band isolation; IMD) and order;

[0073] MSD indication of corresponding threshold (or capability level);

[0074] Power Class: PC3 corresponds to 23dBm, PC2 corresponds to 26dBm, PC1.5 corresponds to 29dBm;

[0075] Aggressor UL and victim DL bandwidth.

[0076] 3. Terminal capabilities.

[0077] The network initiates a capability transmission process to the terminal in the connected state to obtain the terminal's wireless access capability information. After receiving the terminal capability query (UECapabilityEnquiry) message, the terminal sends a terminal capability information (UECapabilityInformation) message to the network.

[0078] The transmission method provided in the embodiment of the present application is described in detail below through some embodiments and their application scenarios in combination with the accompanying drawings.

[0079] Reference Figure 4 , the present application embodiment provides a transmission method, such as Figure 4 As shown, the transmission method includes:

[0080] Step 401: The terminal reports the maximum sensitivity degradation (MSD) information of the combination of target frequency bands, where the MSD information of the combination of target frequency bands includes at least one of the following:

[0081] MSD information of a combination of all frequency bands belonging to the target frequency band;

[0082] MSD information of a combination of partial frequency bands belonging to the target frequency band;

[0083] The MSD information is used to indicate that the terminal has a target MSD value or has a capability that the target MSD value is lower than the MSD value defined by the protocol, and the target MSD value is used to indicate the MSD that the terminal can support or achieve.

[0084] In an embodiment of the present application, the above-mentioned target MSD value can be understood as a lower MSD. The above-mentioned combined MSD information of all frequency bands (Band) belonging to the target frequency band can be understood as the MSD information included in an MSD reporting unit. The above-mentioned combined MSD information of partial frequency bands belonging to the target frequency band can be understood as the MSD information included in one or more MSD reporting units, wherein different MSD reporting units are associated with different numbers of partial frequency bands. Among them, a reporting unit can be understood as a reporting element, a reporting information, a list element (IE) or an information IE. In other words, in an embodiment of the present application, the combined MSD information of the target frequency band includes at least one of the following:

[0085] first MSD information, where the first MSD information belongs to MSD information of a combination of all frequency bands of the target frequency band;

[0086] At least one second MSD information, where the second MSD information is MSD information of a combination of partial frequency bands of the target frequency band, and different second MSD information corresponds to different numbers of frequency bands of the partial frequency bands.

[0087] Among them, one first MSD information corresponds to one MSD reporting unit (which may be called a first MSD reporting unit), and one second MSD information corresponds to one MSD reporting unit (which may be called a second MSD reporting unit).

[0088] In one implementation, the first MSD reporting unit and the second MSD reporting unit are different MSD reporting units.

[0089] Optionally, the number of frequency bands included in the above-mentioned target frequency band can be set according to actual needs. For example, in some embodiments, when the number of frequency bands included in the target frequency band is 3, the MSD information of the combination of all frequency bands belonging to the target frequency band can be understood as the MSD information of the combination of all frequency bands of the three frequency bands. For example, when the number of target frequency bands is 3, the MSD information of the combination of all frequency bands of the target frequency band can be understood as the MSD information of the combination of three frequency bands, and the MSD information of the combination of some frequency bands of the target frequency band can also be understood as the MSD information of the combination of two frequency bands; the MSD information of the combination of some frequency bands belonging to the target frequency band can be understood as the MSD information of the combination of all frequency bands belonging to two frequency bands. In other words, the MSD information of the combination of some frequency bands belonging to the target frequency band can be understood as the MSD information of the combination of all frequency bands belonging to the first frequency band, wherein the number of the above-mentioned target frequency bands is 3 and the number of the first frequency bands is 2.

[0090] For another example, in some embodiments, when the number of frequency bands included in the target frequency band is 4, the MSD information of the combination of all frequency bands belonging to the target frequency band can be understood as the MSD information of the combination of all frequency bands belonging to the 4 frequency bands; the MSD information of the combination of some frequency bands belonging to the target frequency band can be understood as including at least one of the following: the MSD information of the combination of 3 frequency bands in the target frequency band and the MSD information of the combination of 2 frequency bands in the target frequency band. In other words, the MSD information of the combination of some frequency bands belonging to the target frequency band can be understood as including at least one of the following: the MSD information of the combination of all frequency bands belonging to the combination of the first frequency band and the MSD information of the combination of all frequency bands belonging to the combination of the second frequency band, wherein the target frequency band can be understood as 4 frequency bands, the first frequency band can be understood as 3 frequency bands, and the second frequency band combination can be understood as 2 frequency bands.

[0091] It is understandable that the UE can report an MSD information set (MSDset) for a combination of frequency bands with different numbers of frequency bands. All MSD information sets are combined to form the overall MSD information, or called the MSD summary table. Alternatively, the UE reports MSD information separately for combinations of frequency bands with different numbers of frequency bands. By separately reporting MSD information sets or MSD information for combinations of frequency bands with different numbers of frequency bands, repeated reporting of some Band combinations can be avoided, the signaling size can be reduced, and thus resource overhead can be reduced.

[0092] It should be noted that, assuming that the MSD information of the combination of target frequency bands is the MSD information of the combination of all frequency bands belonging to the target frequency band, the above-mentioned terminal reports the maximum sensitivity degradation MSD information of the combination of target frequency bands, which can be understood as the terminal reports the maximum sensitivity degradation MSD information of the combination of at least one target frequency band. Among them, the number of frequency bands of different target frequency bands is the same or different, for example, different target frequency bands can have different frequency bands, but the number of frequency bands is the same.

[0093] In an embodiment of the present application, the terminal reports the maximum sensitivity degradation MSD information of the combination of target frequency bands, and the MSD information of the combination of target frequency bands includes at least one of the following: MSD information of the combination of all frequency bands belonging to the target frequency band; MSD information of the combination of some frequency bands belonging to the target frequency band; wherein the MSD information is used to indicate that the terminal has a target MSD value or has a target MSD value lower than the MSD value defined by the protocol, and the target MSD value is used to indicate the MSD that the terminal can support or achieve. In this way, the reporting behavior of lower MSD information is clarified, which helps the network to schedule the terminal.

[0094] Furthermore, since the MSD information of the combination of all frequency bands belonging to the target frequency band and the MSD information of the combination of some frequency bands belonging to the target frequency band are reported through different MSD reporting units, compared with the terminal directly reporting the MSD information through the signaling framework of the terminal capability information, repeated reporting of some Band combinations can be avoided. Therefore, the embodiment of the present application can reduce the signaling size, thereby reducing resource overhead.

[0095] Optionally, in some embodiments, the target frequency band includes 2 frequency bands, 3 frequency bands or N frequency bands, N is an integer greater than 3, and the combined MSD information of the target frequency bands includes at least one of the following:

[0096] The MSD information of the combination of two frequency bands is the MSD information of the combination of all frequency bands belonging to the two frequency bands or the MSD information of the combination of some frequency bands belonging to M frequency bands, where M is 3 or N, and the MSD information of the combination of the two frequency bands includes at least one of the following: the MSD information corresponding to the situation where the harmonics or harmonic mixtures generated by a single uplink fall into the victim frequency band for reception; the MSD information corresponding to the situation where the intermodulation interference generated by the two uplink frequency bands falls into the downlink range of any frequency band;

[0097] MSD information of a combination of three frequency bands, wherein the MSD information of the combination of the three frequency bands is the MSD information of the combination of all frequency bands belonging to the three frequency bands or the MSD information of the combination of some frequency bands belonging to N frequency bands, and the MSD information of the combination of the three frequency bands includes the MSD information corresponding to the situation where the intermodulation interference generated by the two uplink frequency bands falls within the downlink range of the third frequency band;

[0098] The combined MSD information of N frequency bands, wherein the combined MSD information of N frequency bands is the combined MSD information of all frequency bands belonging to the N frequency bands, and the combined MSD information of N frequency bands includes the MSD information corresponding to the situation where the intermodulation interference generated by N-1 uplink frequency bands falls within the downlink range of the Nth frequency band.

[0099] In an embodiment of the present application, when a combination of three frequency bands falls back to a combination of two frequency bands, the MSD information of all frequency bands of the combination of two frequency bands can be used. That is to say, when the network side device determines the MSD information of the terminal, for a combination of N frequency bands that falls back to a combination of (N-1) frequency bands, the MSD information of all frequency bands of the combination of (N-1) frequency bands is used.

[0100] Optionally, in some embodiments, the combined MSD information of the target frequency band satisfies at least one of the following:

[0101] The MSD information of the combination of all frequency bands belonging to the target frequency band is placed in the MSD reporting unit corresponding to the combination of all frequency bands;

[0102] The MSD information of the combination of the partial frequency bands belonging to the target frequency band is placed in the MSD reporting unit corresponding to the combination of the partial frequency bands;

[0103] In one reporting message, the MSD information of the combination of partial frequency bands belonging to the target frequency band is included only once, or is not included repeatedly.

[0104] In the embodiment of the present application, the MSD reporting unit corresponding to the combination of all frequency bands is different from the MSD reporting unit corresponding to the combination of some frequency bands.

[0105] Optionally, in some embodiments, the combined MSD information of the target frequency bands satisfies:

[0106] The MSD information of the combination of all frequency bands belonging to the target frequency band and the MSD information of the combination of part of frequency bands belonging to the target frequency band are divided into different tables or lists.

[0107] In the embodiment of the present application, each table or list is used to carry the MSD information of a combination corresponding to a number of frequency bands, and different tables or lists correspond to the MSD information of combinations of different numbers of frequency bands. For example, the MSD information of a combination of 2 frequency bands belongs to one table or list; the MSD information of a combination of 3 frequency bands belongs to another table or list.

[0108] That is, in an embodiment of the present application, the MSD information of the combination of the above-mentioned target frequency bands may include multiple tables or lists, wherein each table or list corresponds to the MSD information of all frequency bands of a combination of 2, 3 or N frequency bands, respectively, wherein each row or each item in the table or list includes at least the following information:

[0109] Carrier aggregation information;

[0110] Victim frequency band or downlink frequency band information;

[0111] MSD value or a serial number representing the MSD value;

[0112] MSD type (Type) or source MSD (Source of MSD).

[0113] Regarding the serial number of the MSD value, in some embodiments, 0 can represent 0dB, 1 represents 5dB, 2 represents 10dB, 3 represents 15dB, and 4 represents 20dB. In this way, by using serial numbers instead of MSD values ​​in the table, the reporting difficulty can be reduced and resource overhead can be saved.

[0114] For example, the MSD information of all frequency bands in a combination of 2 frequency bands may be reported as shown in Table 1 below, and the MSD information of all frequency bands in a combination of 3 frequency bands may be reported as shown in Table 2 below.

[0115] Table 1:

[0116] NR-CA Victim band or DL MSD dB MSD Type or Source of MSD CA_n1-n3 n1 23 IMD3 CA_n1-n3 n3 3 Cross band isolation CA_n1-n78 n78 8 IMD4 CA_n3-n78 n78 23 Harmonics CA_n3-n78 n3 26 IMD2 CA_n3-n78 n3 8 IMD4 CA_n3-n78 n3 8 Harmonic mixing

[0117] Among them, CA_n1-n3 in the first column indicates the combination of frequency bands n1 and n3, n1 in the second column indicates that Victimband or DL ​​is n1, 23 in the third column indicates that the MSD value is 23db, IMD3 in the fourth column indicates that MSD Type is IMD3, and Cross band isolation in the fourth column indicates that Source of MSD is Cross band isolation.

[0120] Optionally, in the above table, MSD values ​​may be provided respectively according to different power levels.

[0121] It should be noted that, in an embodiment of the present application, after the network-side device receives the MSD information of the combination of target frequency bands, it can retrieve the MSD information corresponding to the number of frequency bands to obtain the MSD value of a certain frequency band combination. For example, for a combination of 3 frequency bands, the MSD information of all frequency bands of the corresponding combination of 3 frequency bands is searched; for a combination of 3 frequency bands that falls back to 2 frequency bands, the MSD information of all frequency bands of the corresponding combination of 2 frequency bands is searched. In other words, the MSD information corresponding to a combination of a specific frequency band considers the MSD information related to the number of multiple frequency bands, for example, including at least one of the following:

[0122] MSD information of all frequency bands belonging to this specific frequency band combination;

[0123] All MSD information of the combination of partial frequency bands is reported as the MSD information of the combination of this specific frequency band, wherein the combination of partial frequency bands is the combination of some frequency bands in this specific frequency band combination.

[0124] For example, the frequency band combination is CA_n1-n3-n78, and the corresponding MSD information of the combination of all frequency bands is specifically shown in Table 3 below; the MSD information of the corresponding combination of partial frequency bands, that is, the MSD information of the combination of fallback frequency bands, refers to the MSD information of the combination of low-order frequency bands, as shown in Table 4. Among them, all frequency bands corresponding to the frequency band combination CA_n1-n3-n78 include frequency bands n1, n3 and n78. The partial frequency bands corresponding to the frequency band combination CA_n1-n3-n78 include two of n1, n3 and n78. The combination of 2 frequency bands is a combination of low-order frequency bands relative to the combination of 3 frequency bands; the combination of 3 frequency bands is a combination of high-order frequency bands relative to the combination of 2 frequency bands.

[0161] All frequency bands belonging to the target frequency band do not include frequency band combinations that do not need to be reported;

In some embodiments, the UE only reports the third frequency band combination that the network side device needs to report. For example, if the network side device needs to report CA_n1-n3, the UE reports CA_n1-n3, CA_n1-n3-nX, X=78 and other combinations including CA_n1-n3.

[0164] Optionally, when the configuration information includes a frequency band to be reported, the combined MSD information of the target frequency band may satisfy at least one of the following:

For example, in Table 5 below, the network-side device does not need to report n3 as the relevant MSD information for the uplink, so the UE does not need to report the item with n3 as the uplink frequency band (i.e., the first row in the table), thereby saving reporting overhead.
