<Knowledge of the inventor leading to this disclosure>
(Network signaling; NS)
From the viewpoint of interference protection by radio waves in a specific frequency band in a specific area, network signaling (NS) is introduced in a wireless communication system such as LTE or NR. NS is an example of notification of information from the base station to the terminal.

The NS is, for example, associated (or "associated" or "associated" with a particular band. When a terminal using that band receives an NS from a base station, it follows the parameters of the interference provisions indicated by the received NS. Operate (for example, transmit power control).

The value of NS (which may be referred to as the "NS label") may be indicated in a higher layer signal such as RRC signaling. "RRC" is an abbreviation for radio resource control.

The NS label may be associated with, for example, parameters related to interference regulations. An example of a parameter related to the interference regulation is "additional Spectrum Emission". The NS label may indicate additional provisions (or restrictions) on additional spurious emissions. The provision regarding spurious is one of the interference provisions.

(Interference rules to which NS applies)
Regarding the interference provision to which NS is applied, "6.5.2.3 Additional spectrum emission mask" and "6.5.3.3 Additional spurious emissions" are described in Non-Patent Document 1. In addition to these interference provisions, NS may be used, for example, to set test conditions for uplink (UL) reception sensitivity.

“Spectrum emission” is used as a term meaning, for example, out-of-band emission caused by modulation processing and non-linearity in a transmitter, and is referred to as “spectrum emission mask, SEM” in terms of its limitation. The term is used.

"Spurious emissions" (sometimes abbreviated as "spurious") means radiation caused by frequency components that are not intended due to the characteristics of the transmitter. For example, spurious emissions can result from harmonic emissions, parasitic emissions, intermodulation products, or frequency conversion products.

Examples of NS values related to out-of-band radiation (limitation) include "NS_35", "NS_04", "NS_03", "NS_21", and "NS_06". On the other hand, as an example of NS values related to (transmission) spurious, "NS_04", "NS_18", "NS_43", "NS_37", "NS_38", "NS_39", "NS_40", "NS_41", "NS_42", Examples thereof include "NS_21", "NS_24", and "NS_27".

(Regulated difference regarding FR2 transmission spurious between CEPT and 3GPP)
By the way, the inventor of the present application has found that there is a difference in the interference regulation between 3GPP and CEPT. For example, there is a difference between 3GPP and CEPT in terms of spurious regulations. Therefore, it will be considered to modify the 3GPP transmission spurious provisions to match the millimeter-wave spurious provisions under discussion at CEPT.

"CEPT" is an abbreviation for "European Conference of Postal and Telecommunications Administrations". "FR2" is an abbreviation for "frequency range 2" and represents, for example, a frequency band including a frequency of 24 GHz or higher (for example, 24.25 GHz to 52.6 GHz). On the other hand, "FR1" represents, for example, a frequency band including frequencies of 6 GHz band or less (for example, 450 MHz to 6,000 MHz; also referred to as "sub 6").

For example, as shown in FIG. 3, the upper limit of the frequency range that satisfies the requirement that the maximum level of transmission spurious is "-30 dBm" and the measurement bandwidth is "1 MHz" is set from "12.75 GHz" to "7.25 GHz". Will be considered for downward revision.

In addition, with this downward revision, for example, as shown in FIG. 3, the maximum level of transmission spurious in the frequency range of "7.25 GHz ≤ f ≤ 2nd harmonic of the upper frequency edge of the UL operating band in GHz". , And modifications to add "-10 dBm" and "100 MHz" as candidates for values that satisfy the measurement bandwidth, respectively, are considered.

In the proposed amendment illustrated in FIG. 3, the requirements are current in countries, regions, or regions that use the band 7.25-12.75 GHz compared to the current 3GPP provisions (eg, Non-Patent Document 1). It becomes a looser regulation than. On the other hand, in countries, regions, or regions that use the band of 12.75 GHz or higher, the requirements are stricter than the current ones.

(Concerns about revision of 3GPP regulations)
Here, in the regulations (at least Japan) stipulated based on the current 3GPP regulations, and the terminals created in accordance with the regulations, the 3GPP regulations are amended for the following reasons A and Depending on B, it can be assumed that it is unacceptable.

(A) If the 3GPP regulations are relaxed from the regulations stipulated based on the current 3GPP regulations, terminals that comply with the 3GPP regulations cannot meet the regulations of the country concerned and cannot enter the market. Is a concern (barriers to entry for global terminals).

(B) If the current 3GPP regulations are revised to be stricter than the current regulations, there is a possibility that terminals created based on the regulations will not comply with the 3GPP regulations.

Regarding the difference between 3GPP and CEPT regarding the interference regulation, for example, the following solutions (1) to (4) can be considered.
(1) Amend "General Spurious" of 3GPP regulations to conform to CEPT regulations (2) Amend "General Spurious" of 3GPP regulations to conform to CEPT, and stipulate NS for laws and regulations that are barriers to entry (3) ) The 3GPP regulation "General Spurious" is not amended, and NS for Europe is stipulated. (4) After the amendment of the regulations that are barriers to entry, the 3GPP regulation "General Spurious" is amended according to CEPT.

Solution (1) cannot solve the concern about barriers to entry as mentioned above. Since the discussion of solution (4) is not completed within 3GPP, there may be a concern that it will take a long time to revise it, or that it cannot be revised when considering the impact on adjacent systems, for example.

Also, in addition to the transmission spurious, the CEPT regulation may differ from the 3GPP regulation for the reception spurious. In the current provisions of 3GPP, NS applies to provisions for transmit spurious and SEM, but not for provisions regarding receive spurious. Therefore, the specified difference regarding the received spurious may not be resolved by the solution (2) and the solution (3).

In addition, regarding FR2 newly introduced in NR, not only the regulations regarding reception spurious but also the regulations regarding radio frequency (RF) characteristics of terminals (hereinafter sometimes referred to as "RF regulations") may be reviewed. There is sex. At that time, different RF regulations may be required between countries, territories or regions, and the current NR coverage may not be sufficient.

Therefore, the inventor of the present application has come to the finding that, for example, the scope of application of NS to the provisions of 3GPP terminals is expanded. Hereinafter, embodiments focusing on the expansion of the scope of application of NS will be described.

Note that the expansion of the application range of NS may be regarded as the expansion of the candidates for possible values of NS (label) according to the specified range of terminal characteristics applied in a certain frequency band.

For example, "NS_35", "NS_04", "NS_03", "NS_21", "NS_06", "NS_04", "NS_18", "NS_43", "NS_37", "NS_38", "NS_39", "NS_40" mentioned above. , "NS_41", "NS_42", "NS_21", "NS_24", and "NS_27", new NS values different from the existing NS values may be specified for the terminal characteristics to be applied. Alternatively, the terminal characteristics to be applied may be indicated by a combination of two or more existing NS values.

The terminal characteristics may include at least one of the transmission RF characteristics and the reception RF characteristics as described later, for example. Candidates for possible values of NS may be associated with the terminal characteristics in a one-to-one relationship or in a one-to-many relationship.

<Base station configuration>
FIG. 1 is a block diagram showing an example of the configuration of the base station 10. The base station 10 includes, for example, a transmission unit 101, a reception unit 102, and a control unit 103.

The base station 10 wirelessly communicates with the terminal 20 (see FIG. 2). For wireless communication between the base station 10 and the terminal 20, for example, at least one of FR1 and FR2 may be applied.

The transmission unit 101 transmits a downlink (DL) signal to the terminal 20. For example, the transmission unit 101 transmits a DL signal under the control of the control unit 103. The DL signal may include NS.

The receiving unit 102 receives the uplink (uplink, UL signal) transmitted from the terminal 20. For example, the receiving unit 102 receives the UL signal under the control of the control unit 103.

The control unit 103 controls the communication operation of the base station 10, including the transmission process of the transmission unit 101 and the reception process of the reception unit 102.

For example, the control unit 103 receives data, control information, and the like from the upper layer and outputs the data to the transmission unit 101. Further, the control unit 103 outputs the data and control information received from the reception unit 102 to the upper layer. Further, the control unit 103 may generate NS and output it to the transmission unit 101, for example.
<Terminal configuration>

FIG. 2 is a block diagram showing an example of the configuration of the terminal 20. The terminal 20 includes, for example, a receiving unit 201, a transmitting unit 202, and a control unit 203.

The terminal 20 wirelessly communicates with the base station 10, for example.

The receiving unit 201 receives the DL signal transmitted from the base station 10. For example, the receiving unit 201 receives the DL signal under the control of the control unit 203.

The transmission unit 202 transmits the UL signal to the base station 10. For example, the transmission unit 202 transmits a UL signal under the control of the control unit 203.

The control unit 203 controls the communication operation of the terminal 20, including the reception process in the reception unit 201 and the transmission process in the transmission unit 202. For example, the control unit 203 receives data, control information, and the like from the upper layer and outputs the data to the transmission unit 202. Further, the control unit 203 outputs, for example, the data and control information received from the reception unit 201 to the upper layer.

Further, the control unit 203 may control the operation of the terminal 20, for example, at least one operation of the transmission unit 202 and the reception unit 201 according to the NS included in the DL signal. As an example of control, a parameter that defines at least one operation of the transmitting unit 202 and the receiving unit 201 may be set to a value that satisfies the interference regulation indicated by NS. As an example of parameter setting, it is possible to control (for example, limit) the transmission power by the transmission unit 202 by setting the parameter related to the transmission power to a value satisfying the interference regulation indicated by NS.

<Expansion of NS coverage>
The scope of the provisions regarding the characteristics or performance of the terminal 20 of 3GPP to which NS is applied (hereinafter, may be abbreviated as "terminal regulation") is expanded. Due to the expansion of the scope of application of NS, for example, the characteristics or performance of the terminal 20 that may cause interference differs depending on the base station 10 to which the terminal 20 is connected, or in other words, the country, region or region where the base station 10 is installed. It becomes possible to request the condition from the terminal 20.

As a non-limiting example, the scope of application of NS may be extended to any one or a combination of two or more of the following (a) to (c).

(A) Regulations regarding other transmission RF characteristics that are different from the transmission spurious and SEM described above (b) Regulations regarding reception RF characteristics such as reception spurious or reception sensitivity (c) Terminal regulations that are different from the regulations regarding RF characteristics (for example, Radio resource management (RRM) regulations or other terminal regulations)

In other words, in the present embodiment, the NS may be associated with the terminal characteristics of the second regulation different from the first regulation regarding the transmission spurious and the out-of-band radiation limitation, which are the terminal characteristics in a certain frequency band. A non-limiting example of the second provision is any one or more of the above (a) to (c).

<Example of extension to the regulation regarding transmission RF characteristics>
An example of provisions for transmit RF characteristics that differ from transmit spurious and SEM is for "Maximum output power". For example, in a place (for example, a facility such as a hospital) or area where a limit on the maximum transmission power is required, the terminal 20 that receives a specific NS from the base station 10 covering the place or area has the following operation (1) and At least one of (2) may be enforced.

(1) Limitation of maximum (peak) EIRP When a specific NS is received, the terminal 20 may limit the maximum EIRP to a value lower than a specified value. "EIRP" is an abbreviation for equivalent isotropically radiated power or effective isotropically radiated power.

For example, in the power class 3 (PC3) terminal 20, when the specified value of the maximum peak EIRP is 43 dBm, the maximum peak EIRP may be limited to 35 dBm or less according to the reception of a specific NS.

Alternatively, the terminal 20 changes the antenna pattern of the terminal 20, for example, by controlling the antenna pattern to a wide angle to reduce the maximum value of the antenna gain, and sets the maximum peak EIRP of the terminal 20. It may be set to the value indicated by NS (for example, the required value) or less. Alternatively, the terminal 20 may set the maximum peak EIRP to a value indicated by NS (for example, a required value) or less by reducing the total radiated power (TRP).

(2) Limitation of maximum TRP When a specific NS is received, the terminal 20 may limit the maximum TRP to a value lower than a specified value. For example, the terminal 20 of the PC3 may limit the maximum TRP to 20 dBm or less in response to the reception of a specific NS when the specified value of the maximum TRP is 23 dBm.

By limiting the specified value of the maximum TRP, it can be assumed that the minimum peak EIRP will be difficult to satisfy. Therefore, the terminal 20 that has received the specific NS may be allowed to relax (reduce) the required value of the minimum peak EIRP.

<Example of extension to the regulation regarding reception RF characteristics>
An example of a receive RF characteristic is a regulation relating to receive spurious. For example, an NS may be specified indicating that the terminal 20 should satisfy the required value for receiving spurious. The terminal 20 that has received the NS from the base station 10 that covers a certain place or area may determine or interpret, for example, that the required value regarding the reception spurious specified in association with the received NS should be satisfied. ..

The terminal 20 that satisfies the required value may continuously perform wireless communication (for example, millimeter wave communication). The terminal 20 that does not satisfy the required value may operate as follows, for example, in order to satisfy the required value regarding the reception spurious.

For example, the terminal 20 may reduce reception spurious by changing the parameter settings of an internal circuit such as a built-in transmitter or a clock circuit of a CPU. Alternatively, the terminal 20 may control to stop the operation of some transmitters or clock circuits. The part of the transmitter or clock circuit may be a transmitter in a wireless circuit in the terminal 20, or may be a transmitter or a clock circuit of a peripheral device such as an audio device.

Alternatively, the terminal 20 may satisfy the required value by reducing the received spurious by another method.

The required value for reception spurious specified in association with NS may be a value relaxed from the specification of 3GPP (for example, a value larger than the power level of spurious), for example, general reception. Regarding spurious regulations, NS for specific countries, regions or regions may be specified while maintaining (without amending) the current 3GPP regulations and allowing relaxed regulations in a specific frequency band.

For example, in order to avoid barriers to entry in Japan due to legal differences between Japan and Europe, NS for Europe may be stipulated. As a non-limiting example, if spurious regulations differ between Japan and Europe in the range of 7.25 GHz to 12.75 GHz, then some (specific) frequency bands of the specified frequency band are specified. NS to change the value may be specified for Europe. In this case, for example, even if the terminal 20 does not satisfy the provisions regarding general reception spurious, millimeter-wave communication is possible by receiving the NS.

As described above, according to the above-described embodiment, the terminal 20 can realize proper operation in accordance with the provisions regarding the terminal characteristics according to the frequency band.

When "include", "including" and variations thereof are used in the present disclosure, these terms are as comprehensive as the term "comprising". Is intended. Furthermore, the term "or" used in the present disclosure is intended not to be an exclusive OR.

The wireless frame may be composed of one or more frames in the time domain. Each one or more frames in the time domain may be referred to as a subframe. Subframes may further consist of one or more slots in the time domain. The subframe may have a fixed time length (eg, 1 ms) that is independent of numerology.

The numerology may be a communication parameter that applies to at least one of the transmission and reception of a signal or channel. Numerology includes, for example, subcarrier interval (SCS: SubCarrier Spacing), bandwidth, symbol length, cyclic prefix length, transmission time interval (TTI: Transmission Time Interval), number of symbols per TTI, wireless frame configuration, transmission / reception. At least one of a specific filtering process performed by the machine in the frequency domain, a specific windowing process performed by the transmitter / receiver in the time domain, and the like may be indicated.

The slot may be composed of one or more symbols (OFDM (Orthogonal Frequency Division Multiplexing) symbols, SC-FDMA (Single Carrier Frequency Division Multiple Access) symbols, etc.) in the time domain. Slots may be unit of time based on numerology.

The slot may include a plurality of mini slots. Each minislot may consist of one or more symbols in the time domain. Further, the mini slot may be called a sub slot. A minislot may consist of a smaller number of symbols than the slot. A PDSCH (or PUSCH) transmitted in time units larger than the minislot may be referred to as a PDSCH (or PUSCH) mapping type A. The PDSCH (or PUSCH) transmitted using the minislot may be referred to as PDSCH (or PUSCH) mapping type B.

The wireless frame, subframe, slot, mini slot and symbol all represent the time unit when transmitting a signal. The radio frame, subframe, slot, minislot and symbol may have different names corresponding to each.

For example, one subframe may be called a transmission time interval (TTI), a plurality of consecutive subframes may be called TTI, and one slot or one minislot may be called TTI. You may. That is, at least one of the subframe and TTI may be a subframe (1 ms) in existing LTE, a period shorter than 1 ms (eg, 1-13 symbols), or a period longer than 1 ms. It may be. The unit representing TTI may be called a slot, a mini slot, or the like instead of a subframe.

Here, TTI refers to, for example, the minimum time unit of scheduling in wireless communication. For example, in the LTE system, the base station schedules each user terminal to allocate radio resources (frequency bandwidth that can be used in each user terminal, transmission power, etc.) in TTI units. The definition of TTI is not limited to this.

The TTI may be a transmission time unit such as a channel-encoded data packet (transport block), a code block, or a code word, or may be a processing unit such as scheduling or link adaptation. When a TTI is given, the time interval (for example, the number of symbols) to which the transport block, code block, code word, etc. are actually mapped may be shorter than the TTI.

When one slot or one mini slot is called TTI, one or more TTIs (that is, one or more slots or one or more mini slots) may be the minimum time unit for scheduling. Further, the number of slots (number of mini-slots) constituting the minimum time unit of the scheduling may be controlled.

A TTI having a time length of 1 ms may be referred to as a normal TTI (TTI in LTE Rel. 8-12), a normal TTI, a long TTI, a normal subframe, a normal subframe, a long subframe, a slot, or the like. TTIs shorter than normal TTIs may be referred to as shortened TTIs, short TTIs, partial TTIs (partial or fractional TTIs), shortened subframes, short subframes, minislots, subslots, slots, and the like.

The long TTI (for example, normal TTI, subframe, etc.) may be read as a TTI having a time length of more than 1 ms, and the short TTI (for example, shortened TTI, etc.) is less than the TTI length of the long TTI and 1 ms. It may be read as a TTI having the above TTI length.

The resource block (RB) is a resource allocation unit in the time domain and the frequency domain, and may include one or a plurality of continuous subcarriers in the frequency domain. The number of subcarriers contained in the RB may be the same regardless of the numerology, and may be, for example, 12. The number of subcarriers contained in the RB may be determined based on numerology.

Further, the time domain of RB may include one or more symbols, and may have a length of 1 slot, 1 mini slot, 1 subframe, or 1 TTI. Each 1TTI, 1 subframe, etc. may be composed of one or a plurality of resource blocks.

In addition, one or more RBs include a physical resource block (PRB: Physical RB), a sub-carrier group (SCG: Sub-Carrier Group), a resource element group (REG: Resource Element Group), a PRB pair, an RB pair, and the like. May be called.

Further, the resource block may be composed of one or a plurality of resource elements (RE: Resource Element). For example, 1RE may be a radio resource area of 1 subcarrier and 1 symbol.

The bandwidth part (BWP: Bandwidth Part) (which may also be called partial bandwidth) may represent a subset of consecutive common resource blocks (RBs) for a certain neurology in a carrier. Good. Here, the common RB may be specified by the index of the RB with respect to the common reference point of the carrier. PRBs may be defined in a BWP and numbered within that BWP.

The BWP may include a BWP for UL (UL BWP) and a BWP for DL (DL BWP). One or more BWPs may be set in one carrier for the UE.

At least one of the configured BWPs may be active, and the UE may not expect to send or receive a given signal / channel outside the active BWP. In addition, "cell", "carrier" and the like in this disclosure may be read as "BWP".

The above-mentioned structures such as wireless frames, subframes, slots, mini slots and symbols are merely examples. For example, the number of subframes contained in a wireless frame, the number of slots per subframe or wireless frame, the number of minislots contained within a slot, the number of symbols and RBs contained in a slot or minislot, included in the RB. The number of subcarriers, the number of symbols in the TTI, the symbol length, the cyclic prefix (CP: Cyclic Prefix) length, and other configurations can be changed in various ways.

In the present disclosure, if articles are added by translation, for example, a, an and the in English, the disclosure may include that the nouns following these articles are in the plural.

In the present disclosure, the term "A and B are different" may mean "A and B are different from each other". The term may mean that "A and B are different from C". Terms such as "separate" and "combined" may be interpreted in the same way as "different".
