[0007] Problems to be Solved by the Invention

[0008] In future wireless communication systems (e.g., NR), research is being conducted on the use of sub-band non-overlapping full duplex (SBFD) in communication between a terminal (user terminal, User Equipment (UE)) and a network (NW, e.g., a base station).

[0035] (Sub-band non-overlapping full duplex (SBFD))

[0036] In LTE before Rel.14, Frequency Division Duplex (FDD) was mainly applied, and Time Division Duplex (TDD) was also supported.

[0037] On the other hand, in NR after Rel.15, TDD is mainly studied, and FDD is also supported (e.g., migration of the LTE band).

[0038] In FDD, DL reception and UL transmission can be performed simultaneously, which is preferable from the perspective of reducing latency. On the other hand, in FDD, the resource ratio of DL and UL is fixed (e.g., 1:1).

[0039] In TDD, the ratio of DL and UL resources can be changed. For example, in a general environment where the DL traffic is relatively large, the amount of DL resources can be increased to improve the DL throughput.

[0040] On the other hand, considering the transmission / reception time ratio based on TDD before Rel.16, there is a case where the transmission opportunity of UL signals / channels becomes less than the reception opportunity of DL signals / channels. In such a case, the UE cannot send UL signals / channels frequently, and there is a concern about the delay in sending important UL signals / channels. In addition, since the UL transmission opportunity is less than the DL reception opportunity, there is also a concern about the interference of signals / channels in the UL transmission opportunity. Further, the time resources available for sending UL signals / channels in TDD are limited, so the application of UL coverage extension techniques based on repeated transmission (which can also be referred to as repetition), for example, is also restricted.

[0041] In future wireless communication systems (e.g., after Rel.18), a split duplex method combining TDD and Frequency Division Duplex (FDD) is being studied for UL and DL.

[0042] This duplexing method can also be referred to as sub-band non-overlapping full duplex (SBFD).

[0043] SBFD can also mean, for example, a duplexing method that frequency-division multiplexes DL and UL within a component carrier (CC) of a TDD band or within multiple CCs (within the same band) and can utilize DL and UL simultaneously.

[0044] When this duplexing method is applied to multiple CCs, it can also mean that in a certain time resource where DL can be utilized on a certain CC, UL can be utilized on other CCs.

[0045] Figure 1A It is a diagram showing an example of the setting of TDD defined before Rel.16. Figure 1A In the example shown, for the UE, the time slots / symbols of TDD are set within the bandwidth of one component carrier (CC) (which can also be called a cell, serving cell).

[0046] In Figure 1A In the example shown, the time ratio of DL time slots to UL time slots is 4:1. In such a setting of time slots / symbols in the past TDD, it is not possible to fully ensure UL time resources, and there are concerns about UL transmission delays and reduced coverage performance.

[0047] Figure 1B It is a diagram showing an example of the structure of SBFD. Figure 1B In the example of , within one component carrier (CC), the resources for DL reception and the resources for UL transmission overlap in time. According to such a resource structure, UL resources can be ensured, and the utilization efficiency of resources can be improved.

[0048] For example, as shown in Figure 1B In the example shown, it is assumed that both ends in the frequency domain of one CC are configured as DL, and the UL resources are sandwiched by this DL, so as to avoid and mitigate the generation of cross-link interference (CLI) with adjacent carriers. In addition, a guard area can also be set at the boundary between DL resources and UL resources.

[0049] Considering the complexity of self-interference processing, it is considered that only the base station uses DL resources and UL resources simultaneously. That is, it can also be set as a structure in which in the resources where DL and UL overlap in time, one UE uses DL resources and other UEs use UL resources.

[0050] Figure 2This is a diagram showing an example of the structure of SBFD. In Figure 2 In the example shown, a part of the DL resources in the TDD band is used as UL resources, and the DL and UL overlap in part of the time.

[0051] In Figure 2 In the example shown, for the period of only DL, each of multiple UEs (UE#1 and UE#2 in Figure 2 ) receives the DL channel / signal.

[0052] In addition, during the period when DL and UL overlap in time, a certain UE (UE#1 in the example of Figure 2 ) receives the DL channel / signal, and other UEs (UE#2 in the example of Figure 2 ) transmit the UL channel / signal. During this period, the base station performs simultaneous transmission and reception of DL and UL.

[0053] Furthermore, for the period of only UL, each of multiple UEs transmits the UL channel / signal.

[0054] In existing (e.g., specified up to Rel.15 / 16) NR, the DL frequency resources and UL frequency resources in the carrier used by the UE are respectively set as the DL bandwidth part (Bandwidth Part (BWP)) and UL BWP. In order to switch the DL / UL frequency resources to other DL / UL frequency resources, a mechanism for setting multiple BWPs and adaptation of the BWP is required.

[0055] In addition, in existing NR, the time resources in the TDD carrier used by the UE are set as at least one of DL, UL, and flexible (FL) in the TDD setting.

[0056] A method for setting resources in the time domain and frequency domain when using SBFD is being studied. For example, for Figure 2 UE#1, by setting the resources during the period when DL and UL overlap in the time domain in the same way as the existing DL resources (e.g., on the basis of using frequency domain resource allocation (FDRA) to avoid the part using UL resources), the impact on the specification / UE can be minimized (refer to Figure 3A ).

[0057] In addition, for example, for Figure 2 UE#2, by setting the resources during the period when DL and UL overlap in the time domain in the same way as the existing UL resources (e.g., on the basis of using frequency domain resource allocation (FDRA) to avoid the part using DL resources), the impact on the specification / UE can be minimized (refer toFigure 3B ).

[0058] (DL Transmission Power Setting)

[0059] In the existing NR specifications (up to Rel.17), the channel state information (CSI) feedback derived by the UE is controlled based on the power density of the non-zero power (NZP) channel state information reference signal (CSI-RS) (e.g., the power per resource element (energy per resource element (EPRE))) and the power density of a specific DL channel / signal (e.g., EPRE).

[0060] The UE can also use RRC signaling (RRC information element) to receive information related to the power control offset. This information can be, for example, either powerControlOffset or powerControlOffsetSS.

[0061] powerControlOffset can also represent the ratio (power ratio / power offset) of the EPRE of the PDSCH envisioned when the UE derives CSI feedback to the EPRE of the NZP CSI-RS. powerControlOffset can take values in the range of [-8, 15] dB in steps of 1 dB (stepsize).

[0062] powerControlOffsetSS can also represent the ratio (power ratio / power offset) of the EPRE of the SS / PBCH block envisioned when the UE derives CSI feedback to the EPRE of the NZP CSI-RS.

[0063] (Analysis)

[0064] After Rel.18, in the case of performing SBFD operations, it is necessary to consider the CLI between base stations (inter-gNB (BS)) and the CLI between UEs (inter-UE).

[0065] In the case of inter-UE CLI, the UL transmission of the UE that becomes the source of interference (UE#1, also referred to as the interfering UE / aggressor UE) generates interference to the DL reception of the UE being interfered with (UE#2, also referred to as the interfered UE / victim UE) on the side of the interfered UE (refer to Figure 4A ).

[0066] In this case, from the perspective of the interfered UE, at least one of the following may be desired: improving the DL transmission power for the DL reception of the interfered UE to improve the received signal power, and reducing the UL transmission power of the interfering UE to reduce the interference on the reception of the interfered UE.

[0067] In the case of inter-base station CLI, the DL reception of the interfering UE (UE#1) causes interference on the UL transmission of the interfered UE (UE#2) at the base station side (refer to Figure 4B ).

[0068] In this case, from the perspective of the base station corresponding to the interfered UE, at least one of the following may be desired: reducing the DL transmission power of the interfering UE to reduce interference, and improving the UL transmission power of the interfered UE to improve the received signal power.

[0069] In the case of applying SBFD, consider introducing a more flexible DL transmission power control / indication method. By introducing such a control / indication method, for example, flexible DL transmission power adjustment based on the interference level can be performed.

[0070] Furthermore, in the case of applying SBFD, consider reporting at least one of the following: adjustment of the requested DL transmission power, and the requested UL power density (Power Spectrum Density (PSD)) range. By making such a report, for example, it is considered that the base station can be assisted for DL / UL transmission power control.

[0071] However, research on the DL transmission power control / indication method in the case of applying SBFD, and on the report for DL / UL transmission power control is not sufficient. For example, when introducing these control / indication methods / reports, it is necessary to change the indication of time domain resources and consider the granularity in the frequency domain, etc., for the UE to perform the DL transmission power control / indication method and the expansion of the report for DL / UL transmission power control.

[0072] Therefore, the inventors of the present invention have come up with a control method for DL / UL transmission power related to SBFD operations for solving the above problems.

[0073] The following describes in detail the embodiments related to the present disclosure with reference to the accompanying drawings. The wireless communication methods related to each embodiment can be applied separately or in combination.

[0091] (Wireless communication method)

[0092] <First Embodiment>

[0093] The first embodiment relates to the setting of DL transmission power.

[0094] The UE may also receive parameters related to the DL transmission power (e.g., parameters related to the DL transmission power for SBFD use / non - SBFD use).

[0095] The UE may also assume / judge the received power of the DL channel / signal (e.g., CSI - RS / PDSCH / PDCCH) in the time resource for SBFD use / non - SBFD use based on the parameters related to the DL transmission power (e.g., parameters related to the DL transmission power for SBFD use / non - SBFD use).

[0096] The parameters related to the DL transmission power (e.g., parameters related to the DL transmission power for SBFD use / non - SBFD use) may also be included in the common higher - layer parameters / RRC information elements.

[0097] For example, the higher - layer parameter / RRC information element may also be the setting parameter of the NZP CSI - RS resource (e.g., NZP - CSI - RS - Resource).

[0098] <<Embodiment 1 - 1>>

[0099] More flexible setting / indication of the parameters related to the DL transmission power may also be supported.

[0100] The parameters related to the DL transmission power may, for example, also be parameters related to power offset. The power offset may, for example, also be shown by the ratio of the power density of the first DL channel / signal (e.g., at least one of PDSCH, SS / PBCH block) to the power density of the second DL channel / signal (e.g., CSI - RS).

[0101] The parameters related to the DL transmission power may, for example, also be at least one of the RRC information elements powerControlOffset and powerControlOffsetSS.

[0102] Regarding the parameters related to the DL transmission power, separate (independent) values / parameters may also be set / indicated in the time unit / frequency unit.

[0103] [Embodiment 1 - 1 - 1A]

[0104] Regarding each of the time resources for SBFD use (e.g., time slot / symbol) and non - SBFD use (e.g., time slot / symbol), separate (independent) values of the parameters related to the DL transmission power may also be set / indicated.

[0105] Figure 5A FIG. is an example of the parameters related to the DL transmission power according to Embodiment 1 - 1 - 1A.Figure 5A The information elements described are described using the notation of Abstract Syntax Notation One (ASN.1) (as an example only). Hereinafter, in this disclosure, all the drawings describing the information elements are described using the ASN.1 notation, and the structure and name of the information are only examples.

[0106] In Figure 5A the example shown, parameters related to the DL transmission power included in the setting parameters of the NZP CSI-RS resource received by the UE (e.g., NZP-CSI-RS-Resource) are described.

[0107] In Figure 5A the example shown, the setting parameters of the NZP CSI-RS resource (e.g., NZP-CSI-RS-Resource) include: parameters related to the DL transmission power in the time resource for non-SBFD (powerControlOffset and powerControlOffsetSS) and parameters related to the DL transmission power in the time resource for SBFD (powerControlOffset-SBFD and powerControlOffsetSS-SBFD).

[0108] Alternatively, the UE may judge / conceive the DL transmission power in the time resource for non-SBFD based on the parameters related to the DL transmission power in the time resource for non-SBFD, and judge / conceive the DL transmission power in the time resource for SBFD based on the parameters related to the DL transmission power in the time resource for SBFD.

[0109] For example, the UE may also conceive / judge the ratio between the power density (e.g., EPRE) of a first DL signal (e.g., PDSCH) and the power density (e.g., EPRE) of a second DL signal (e.g., CSI-RS) in the time resource for non-SBFD based on a first parameter (e.g., powerControlOffset).

[0110] For example, the UE may also conceive / judge the ratio between the power density (e.g., EPRE) of a first DL signal (e.g., PDSCH) and the power density (e.g., EPRE) of a second DL signal (e.g., CSI-RS) in the time resource for SBFD based on a second parameter (e.g., powerControlOffset-SBFD).

[0111] For example, the UE may also assume / judge the ratio between the power density (e.g., EPRE) of a first DL signal (e.g., SS / PBCH block) and the power density (e.g., EPRE) of a second DL signal (e.g., CSI-RS) in the time resources for non-SBFD based on a first parameter (e.g., powerControlOffsetSS).

[0112] For example, the UE may also assume / judge the ratio between the power density (e.g., EPRE) of a first DL signal (e.g., SS / PBCH block) and the power density (e.g., EPRE) of a second DL signal (e.g., CSI-RS) in the time resources for SBFD based on a second parameter (e.g., powerControlOffsetSS-SBFD).

[0113] [Embodiment 1-1-1B]

[0114] Regarding the parameter (value) related to the DL transmission power, a parameter indicating the offset between the time resources (e.g., time slots / symbols) for SBFD and the time resources for non-SBFD may also be set / stipulated / indicated.

[0115] In other words, the parameter related to the DL transmission power in the time resources (e.g., time slots / symbols) for SBFD may also be represented by an offset (based on it) from the parameter related to the DL transmission power in the time resources (e.g., time slots / symbols) for non-SBFD.

[0116] The parameter indicating the offset may be set using RRC signaling, may be predefined in the specification, may be indicated using DCI / MAC CE, or may be notified to the UE through a combination of them.

[0117] For example, for the UE, when the parameter indicating the offset is set using RRC and is dynamically indicated (e.g., using DCI / MAC CE), the parameter indicating the offset (the offset value represented by this parameter) may be set / indicated for each CSI-RS resource, may be set for each CSI-RS resource set, or may be set / indicated commonly for multiple (e.g., all) CSI-RS resources.

[0118] Figure 5B It is a diagram showing an example of the parameter related to the DL transmission power involved in Embodiment 1-1-1B.

[0119] In Figure 5BIn the example shown, the parameters related to the DL transmission power included in the setting parameters of the NZP CSI-RS resource (e.g., NZP-CSI-RS-Resource) received by the UE are described.

[0120] In Figure 5B In the example shown, the setting parameters of the NZP CSI-RS resource (e.g., NZP-CSI-RS-Resource) include parameters related to the DL transmission power in the time resources for non-SBFD (powerControlOffset and powerControlOffsetSS) and parameters indicating the offset between the time resources for non-SBFD and the time resources for SBFD (powerControlOffset-SBFD-offset and powerControlOffsetSS-SBFD-offset).

[0121] Alternatively, the UE can determine / assume the DL transmission power in the time resources for non-SBFD based on the parameters related to the DL transmission power in the time resources for non-SBFD, and determine / assume the DL transmission power in the time resources for SBFD based on the parameters related to the DL transmission power in the time resources for non-SBFD and the parameters indicating the offset between the time resources for non-SBFD and the time resources for SBFD.

[0122] For example, the UE can also assume / determine the ratio between the power density (e.g., EPRE) of the first DL signal (e.g., PDSCH) and the power density (e.g., EPRE) of the second DL signal (e.g., CSI-RS) in the time resources for non-SBFD based on the first parameter (e.g., powerControlOffset).

[0123] For example, the UE can also assume / determine the ratio between the power density (e.g., EPRE) of the first DL signal (e.g., PDSCH) and the power density (e.g., EPRE) of the second DL signal (e.g., CSI-RS) in the time resources for SBFD based on at least one of the first parameter (e.g., powerControlOffset) and the second parameter (e.g., powerControlOffset-SBFD-offset).

[0124] For example, the UE may also conceive / judge, based on a first parameter (e.g., powerControlOffsetSS), the ratio between the power density (e.g., EPRE) of a first DL signal (e.g., SS / PBCH block) and the power density (e.g., EPRE) of a second DL signal (e.g., CSI-RS) in the time resources for non-SBFD.

[0125] For example, the UE may also conceive / judge, based on at least one of a first parameter (e.g., powerControlOffsetSS) and a second parameter (e.g., powerControlOffsetSS-SBFD-offset), the ratio between the power density (e.g., EPRE) of a first DL signal (e.g., SS / PBCH block) and the power density (e.g., EPRE) of a second DL signal (e.g., CSI-RS) in the time resources for SBFD.

[0126] [Embodiment 1-1-2]

[0127] The parameters related to the DL transmission power may also be set / indicated in a specific frequency unit.

[0128] This specific frequency unit may also be, for example, each sub-band level (sub-band unit).

[0129] The size of the sub-band may be predefined in the specification, may be set for the UE using high-layer signaling (e.g., RRC signaling), or may be notified to the UE through their combination.

[0130] The size of the sub-band may also be expressed as an integer multiple of a specific frequency resource (e.g., at least one of 2 times, 4 times, 6 times, and 8 times, etc.).

[0131] The size of the sub-band may also be the same as the size of the sub-band for reports (e.g., CQI / CSI reports) in the sub-band.

[0132] Figure 6A It is a diagram showing an example of the parameters related to the DL transmission power involved in Embodiment 1-1-2.

[0133] In Figure 6A In the example shown, the parameters related to the DL transmission power included in the set parameters (e.g., NZP-CSI-RS-Resource) of the NZP CSI-RS resource received by the UE are described.

[0134] In Figure 6AIn the example shown, in the setting parameters of the NZP CSI-RS resource (for example, NZP-CSI-RS-Resource), parameters related to the DL transmission power (not using the DL transmission of subbands) (powerControlOffset and powerControlOffsetSS) and parameters representing the DL transmission power of the subband level (powerControlOffset-subband and powerControlOffsetSS-subband) are included.

[0135] Alternatively, the UE may determine / conceive the DL transmission power of the DL transmission not using subbands based on the parameters related to the DL transmission power (not using the DL transmission of subbands), and determine / conceive the DL transmission power of the DL transmission using a specific subband based on the parameters related to the DL transmission power of the subband level.

[0136] For example, the UE may also conceive / determine, based on the first parameter (for example, powerControlOffset), the ratio between the power density (for example, EPRE) of the first DL signal (for example, PDSCH) and the power density (for example, EPRE) of the second DL signal (for example, CSI-RS) for the DL transmission not using subbands.

[0137] For example, the UE may also conceive / determine, based on the second parameter (for example, powerControlOffset-subband), the ratio between the power density (for example, EPRE) of the first DL signal (for example, PDSCH) and the power density (for example, EPRE) of the second DL signal (for example, CSI-RS) for the DL transmission using a specific subband.

[0138] For example, the UE may also conceive / determine, based on the first parameter (for example, powerControlOffsetSS), the ratio between the power density (for example, EPRE) of the first DL signal (for example, SS / PBCH block) and the power density (for example, EPRE) of the second DL signal (for example, CSI-RS) for the DL transmission not using subbands.

[0139] For example, the UE may also conceive / determine, based on the second parameter (for example, powerControlOffsetSS-subband), the ratio between the power density (for example, EPRE) of the first DL signal (for example, SS / PBCH block) and the power density (for example, EPRE) of the second DL signal (for example, CSI-RS) for the DL transmission using a specific subband.

[0140] [Embodiment 1-1-3]

[0141] The above-described Embodiment 1-1-1A / 1-1-1B and the above-described Embodiment 1-1-2 can also be combined and applied.

[0142] Parameters related to the DL transmission power of each subband level for the time resources (e.g., time slots / symbols) of SBFD and parameters related to the DL transmission power of each subband level for the time resources (e.g., time slots / symbols) of non-SBFD can also be set as separate (independent) values / parameters.

[0143] Figure 6B It is a diagram showing an example of parameters related to the DL transmission power involved in Embodiment 1-1-3.

[0144] In Figure 6B In the example shown, parameters related to the DL transmission power included in the setting parameters (e.g., NZP-CSI-RS-Resource) of the NZP CSI-RS resource received by the UE are described.

[0145] In Figure 6B In the example shown, in the setting parameters (e.g., NZP-CSI-RS-Resource) of the NZP CSI-RS resource, parameters related to the DL transmission power of the time resources for non-SBFD (powerControlOffset and powerControlOffsetSS) and parameters related to the DL transmission power of the subband level in the time resources for SBFD (powerControlOffset-sbfb-subband and powerControlOffsetSS-sbfb-subband) are included.

[0146] Alternatively, the UE can determine / conceive the DL transmission power in the time resources for non-SBFD based on the parameters related to the DL transmission power in the time resources for non-SBFD, and determine / conceive the DL transmission power of the subband level in the time resources for SBFD based on the parameters related to the DL transmission power of the subband level in the time resources for SBFD.

[0147] For example, the UE can also conceive / determine the ratio between the power density (e.g., EPRE) of the first DL signal (e.g., PDSCH) and the power density (e.g., EPRE) of the second DL signal (e.g., CSI-RS) in the time resources for non-SBFD based on the first parameter (e.g., powerControlOffset).

[0148] For example, the UE may also assume / judge, based on a second parameter (e.g., powerControlOffset-sbfb-subband), the ratio between the power density (e.g., EPRE) of a first DL signal (e.g., PDSCH) at the subband level in the time resources for SBFD and the power density (e.g., EPRE) of a second DL signal (e.g., CSI-RS).

[0149] For example, the UE may also assume / judge, based on a first parameter (e.g., powerControlOffsetSS), the ratio between the power density (e.g., EPRE) of a first DL signal (e.g., SS / PBCH block) in the time resources not for SBFD and the power density (e.g., EPRE) of a second DL signal (e.g., CSI-RS).

[0150] For example, the UE may also assume / judge, based on a second parameter (e.g., powerControlOffsetSS-sbfb-subband), the ratio between the power density (e.g., EPRE) of a first DL signal (e.g., SS / PBCH block) at the subband level in the time resources for SBFD and the power density (e.g., EPRE) of a second DL signal (e.g., CSI-RS).

[0151] In addition, Figure 6B The examples shown illustrate the combination of the above-described Embodiments 1-1-A and 1-1-2, but Embodiments 1-1-B and 1-1-2 may also be combined.

[0152] According to the above Embodiment 1-1, it is possible to appropriately and flexibly define / set the parameters related to the DL transmission power notified to the UE.

[0153] 《Embodiment 1-2》

[0154] The parameters related to the DL transmission power may also be dynamically updated / changed (by the base station).

[0155] For example, the base station may also give an indication related to the update / change of the parameters related to the DL transmission power. The UE may also receive indication information related to the update / change of the parameters related to the DL transmission power.

[0156] The UE may also assume / judge the reception power of a DL channel / signal (e.g., CSI-RS / PDSCH / PDCCH) to be transmitted after a specific period has elapsed after receiving the indication information.

[0157] This indication information may also be, for example, information indicating a new value of the parameters related to the DL transmission power.

[0158] In addition, for example, the indication information may also be information indicating an offset value with respect to a value of a parameter related to the DL transmission power that is set.

[0159] One or more offset values may also be indicated. In this case, candidates for the offset value (multiple offset values) may either be defined in advance in the specification, set for the UE using higher layer signaling (RRC / MAC CE), or notified to the UE through a combination thereof. The candidates for the offset value may be specified / set for each configured CSI-RS resource, for each configured CSI-RS resource set, or may be specified / set commonly for multiple (e.g., all) CSI-RS resources (sets).

[0160] For example, the UE may also be indicated, for each CSI-RS resource, an update / change of the value of a parameter related to the DL transmission power.

[0161] This indication may also be performed using DCI / MAC CE.

[0162] [Indication based on DCI]

[0163] The DCI format of this DCI may also be an existing DCI format (specified up to Rel. 17).

[0164] For example, the DCI format may also be a DCI format used in the scheduling of unicast / multicast / broadcast DL (e.g., PDSCH) (e.g., DCI format 1_0 / 1_1 / 1-2 / 4_0 / 4_1 / 4_2).

[0165] In addition, for example, the DCI format may also be a group common DCI format (e.g., DCI format 2_0 / 2_1 / 2-2 / 2_3 / 2_4 / 2_5 / 2_6 / 2_7).

[0166] The DCI format may also be, for example, a DCI format accompanied by a CRC (Cyclic Redundancy Check) scrambled by an existing (specified up to Rel. 17) Radio Network Temporary Identifier (RNTI).

[0167] The DCI format may also include a field (new field) for the update / change of a parameter related to the DL transmission power.

[0168] In addition, fields that are not used when the DCI format does not schedule a channel (e.g., at least one of the HARQ process number field, TCI field, SRI field) can also be used as fields for updating / changing parameters related to DL transmission power.

[0169] At this time, for the confirmation (validation) of the update / change of the parameter related to DL transmission power, (a plurality of) specific fields can also be fixed / set to specific values. For example, for the confirmation (validation) of the update / change of the parameter related to DL transmission power, at least two of the frequency domain resource allocation (FDRA) field, time domain resource allocation (TDRA) field, modulation and coding scheme (MCS) field, redundancy version (RV) field, and new data indicator (NDI) field are fixed / set to a first value (e.g., 0 (or 1)).

[0170] In addition, this DCI format can also be an existing DCI format, and is a DCI format accompanied by a CRC scrambled by a new (specified after Rel.18) RNTI.

[0171] In addition, this DCI format can also be a new (specified after Rel.18) DCI format. This DCI format can be either a UE-specific DCI format or a group-common DCI format.

[0172] [Indicator based on MAC CE]

[0173] This MAC CE can also be a new (specified after Rel.18) MAC CE.

[0174] This MAC CE can also be an existing (specified up to Rel.17) MAC CE.

[0175] This MAC CE can also contain an octet / field for updating / changing parameters related to DL transmission power (the existing MAC CE can also be extended).

[0176] The octet / field for updating / changing parameters related to DL transmission power can also be a new octet / field.

[0177] The octet / field for updating / changing parameters related to DL transmission power can also be an existing octet / field contained in the existing MAC CE. At this time, a specific bit (e.g., a reserved bit) contained in this MAC CE can also be used to indicate that this existing MAC CE is interpreted as a MAC CE for updating / changing parameters related to DL transmission power.

[0178] Next, the application timing of the indication received by the UE is described. The UE may also be instructed to update / change the parameters associated with the DL transmission power for each CSI-RS resource (set).

[0179] The UE may also follow at least one of the following options 1-2-1 to 1-2-3.

[0180] [Option 1-2-1]

[0181] The UE may also apply the indication only once.

[0182] The UE may also apply the indication to the reception of the earliest CSI-RS with the corresponding CSI-RS resource (set) index after a specific period (e.g., X symbols / slots (X is an arbitrary number)) from the end timing (e.g., end symbol / slot) of the received indication (Example 1-2-1-1).

[0183] The UE may also use pre-set parameters / values for the reception of CSI-RS other than the reception of the CSI-RS to which the indication is applied.

[0184] In addition, the UE may also apply the received indication to the reception of CSI-RS in the time resources (e.g., symbols / slots) for SBFD.

[0185] In addition, the UE may not apply the received indication to the reception of CSI-RS in the time resources (e.g., symbols / slots) for non-SBFD. The UE may also assume that the time resources for non-SBFD do not overlap with the time resources for SBFD.

[0186] The UE may also apply the indication to the reception of the earliest CSI-RS with the corresponding CSI-RS resource (set) index in the time resources for SBFD after a specific period (e.g., X symbols / slots (X is an arbitrary number)) from the end timing (e.g., end symbol / slot) of the received indication (Example 1-2-1-2).

[0187] Figure 7 It is a diagram showing an example of the application of the indication related to Option 1-2-1. In Figure 7 In the example shown, the UE receives CSI-RS in CSI-RS opportunities #i to #i+3 of CRI#1.

[0188] The UE may also receive an indication of a change / update of the parameter related to the DL transmission power.

[0189] In Figure 7In the example shown, according to the above Example 1-2-1-1, the UE applies the indication in the first CSI-RS opportunity (CSI-RS opportunity #i) after X symbols from the end of the reception of the indication.

[0190] In Figure 7 In the example shown, according to the above Example 1-2-1-2, the UE applies the indication in the first CSI-RS opportunity (CSI-RS opportunity #i + 1) in the time resource for SBFD after X symbols from the end of the reception of the indication.

[0191] In addition, the CSI-RS in the present disclosure may also be at least one of periodic CSI-RS, semi-persistent CSI-RS, and aperiodic CSI-RS.

[0192] [Option 1-2-2]

[0193] The UE may also apply the indication to DL reception during a specific period.

[0194] This specific period may be either pre-specified in the specification or set for the UE via higher layer signaling (e.g., RRC).

[0195] The UE may also apply the indication to the reception of CSI-RS having a corresponding CSI-RS resource (set) index within a specific period / window (window) starting X symbols / slots (X is an arbitrary number) after the end timing (e.g., end symbol / slot) of the received indication (Example 1-2-2-1).

[0196] The length of this specific period / window may be either pre-specified in the specification or set for the UE using higher layer signaling.

[0197] For example, a timer may be set at the start of this specific period / window. The UE may also determine that this specific period / window continues until the timer expires.

[0198] The UE may also use pre-set parameters / values for the reception of CSI-RS other than the CSI-RS to which the indication is applied.

[0199] In addition, the UE may also apply the received indication to the reception of CSI-RS in the time resource for SBFD (e.g., symbol / slot) within this specific period / window.

[0200] In addition, the UE may not apply the received indication to the reception of CSI-RS in the time resource not for SBFD (e.g., symbol / slot). The UE may also assume that the time resource not for SBFD does not overlap with the time resource for SBFD.

[0201] The UE can also apply the indication to the reception of the CSI-RS having the corresponding CSI-RS resource (set) index in the time resources for SBFD within a specific period / window starting X symbol / slots (X is an arbitrary number) after the end timing of the received indication (e.g., end symbol / slot) (Example 1-2-2-2).

[0202] Figure 8 It is a diagram showing an example of the application of the indication related to Option 1-2-2. In Figure 8 the example shown, the UE receives the CSI-RS in the CSI-RS opportunities #i to #i+3 of CRI#1.

[0203] The UE can also receive an indication of the change / update of the parameter related to the DL transmission power.

[0204] In Figure 8 the example shown, according to the above Example 1-2-2-1, the UE applies the indication in the CSI-RS opportunities (CSI-RS opportunities #i to #i+2) within the window starting X symbols after the end of the reception of the indication.

[0205] In Figure 8 the example shown, according to the above Example 1-2-2-2, the UE applies the indication in the CSI-RS opportunities (CSI-RS opportunities #i+1 and #i+2) in the time resources for SBFD within the window starting X symbols after the end of the reception of the indication.

[0206] [Option 1-2-3]

[0207] The UE can also apply the indication to the DL reception during the period until the reception of the next indication.

[0208] This specific period can be either pre-specified in the specification or set for the UE through higher layer signaling (e.g., RRC).

[0209] The UE can also apply the received indication to the reception of the CSI-RS having the CSI-RS resource (set) index during the period from X symbol / slots (X is an arbitrary number) after the end timing of the received indication (e.g., end symbol / slot) until the reception of the indication related to the update / change of the parameter related to the other (next) DL transmission power (Example 1-2-3-1).

[0210] The UE can also use the pre-set parameters / values for the reception of the CSI-RS other than the CSI-RS for which the indication is applied.

[0211] In addition, the UE may also apply the received indication to the reception of CSI-RS in the time resources (e.g., symbols / slots) for SBFD within the specific period / window.

[0212] In addition, the UE may not apply the received indication to the reception of CSI-RS in the time resources (e.g., symbols / slots) not for SBFD. The UE may also assume that the time resources not for SBFD do not overlap with the time resources for SBFD.

[0213] The UE may also apply the indication to the reception of CSI-RS with the corresponding CSI-RS resource (set) index in the time resources for SBFD during the period from the end timing (e.g., end symbol / slot) of the received indication after passing through X symbols / slots (X is an arbitrary number) until receiving the indication related to the update / change of the parameters related to the DL transmit power of other (next) DL (Example 1-2-3-2).

[0214] Using the above Figure 7 Explain the application of the indication involved in Option 1-2-3. In Figure 7 In the example shown, the UE receives CSI-RS in CSI-RS opportunity #i to #i+3 of CRI#1.

[0215] The UE may also receive an indication of the change / update of the parameters related to the DL transmit power. In Figure 7 In the example shown, the UE may not receive an indication other than this indication.

[0216] In Figure 7 In the example shown, according to the above Example 1-2-3-1, the UE may also apply the indication during the CSI-RS opportunity (CSI-RS opportunity #i to #i+3) within the period from the end of the reception of this indication after passing through X symbols until receiving the next indication.

[0217] In Figure 7 In the example shown, according to the above Example 1-2-3-2, the UE may also apply the indication during the CSI-RS opportunity (#i+1 to #i+3) in the time resources for SBFD within the period from the end of the reception of this indication after passing through X symbols until receiving the next indication.

[0218] In addition, X in the above Options 1-2-1 to 1-2-3 may be either pre-specified in the specification or set for the UE using higher layer signaling (RRC / MAC CE).

[0219] In addition, the above Embodiment 1-1 and Embodiment 1-2 may be combined and applied.

[0220] In addition, the base station (NW) may also send at least one of the settings related to the above-described Embodiment 1-1 and the indication related to the above-described Embodiment 1-2 based on the location information of the UE.

[0221] The UE may also report the location information of the UE to the base station (network). In addition, the UE may be triggered to report the location information.

[0222] The base station may also trigger the reporting of the location information based on specific conditions.

[0223] According to the above Embodiment 1-2, it is possible to appropriately perform the setting / indication / update related to the parameters related to the DL transmission power for the UE.

[0224] <Second Embodiment>

[0225] The second embodiment relates to information related to the power adjustment of the UE's reporting / request (for example, information related to the request for DL transmission power adjustment, information related to the UL power spectral density (PSD)).

[0226] <<Embodiment 2-0>>

[0227] The UE may also send / report at least one of information related to the request for (desired) DL transmission power adjustment and information related to the (desired) UL transmission power spectral density (UL PSD).

[0228] At least one of the information related to the request for DL transmission power adjustment and the information related to the UL power spectral density (PSD) may also include at least one of an indication field related to the time / frequency resource and information related to the spatial domain (spatial resource / beam).

[0229] The indication field related to the time / frequency resource may also be at least one piece of information described in the following Embodiment 2-1.

[0230] The information related to the spatial domain (spatial resource / beam) may also be, for example, information related to one or more beams (beam groups).

[0231] At least one of the information related to the request for DL transmission power adjustment and the information related to the UL power spectral density (PSD) may also include at least one of information related to the (desired) DL transmission power adjustment and information related to the (desired) UL PSD range.

[0232] For example, the UE may also report at least one of the value of the desired power adjustment value and the value of the desired PSD range.

[0233] In addition, for example, the UE may also report an index corresponding to at least one of the desired power adjustment value and the desired PSD range. The correspondence (association / table / list) between the index and at least one of the power adjustment value and the PSD range may be specified in the specification in advance or set for the UE using higher layer signaling (RRC / MAC CE). According to this method, since the UE only reports the index, the signaling overhead of the UE can be reduced.

[0234] In addition, at least one of the (desired) DL transmission power adjustment and the (desired) UL PSD range may also be information for the interfered UE or the interfering UE.

[0235] Hereinafter, in this embodiment, information related to power adjustment (for example, information related to a request for DL transmission power adjustment, information related to UL power spectral density (PSD)) may also be simply referred to as "report".

[0236] <<Embodiment 2-1>>

[0237] The request for (desired) DL transmission power adjustment may also represent an adjustment per time / frequency resource unit.

[0238] The request for (desired) UL PSD range may also represent a range per time / frequency resource unit.

[0239] In the present disclosure, the range of (reported / requested) time / frequency / space resources may also mean the unit (minimum unit) of (reported / requested) time / frequency / space resources.

[0240] At least one of the resource range in the time domain, the time domain resource range, and the indication / reporting granularity may be specified in the specification in advance or set for the UE using higher layer signaling (RRC / MAC CE).

[0241] The indication / reporting granularity may also be below the time domain resource range of the indication / reporting.

[0242] For example, at least one of the request (command) for (desired) DL transmission power adjustment and the request for (desired) UL PSD range may also represent a value for a specific time resource. The specific time resource may also be, for example, X time slots / symbols / time slot groups / symbol groups (X is an arbitrary number).

[0243] In addition, in the present disclosure, time slot groups, one or more time slots, one or more time slots for SBFD / non-SBFD may be rewritten with each other. In addition, in the present disclosure, symbol groups, one or more symbols, one or more symbols for SBFD / non-SBFD may be rewritten with each other.

[0244] For example, the UE may also determine the granularity of indication / reporting on a per time slot / symbol / time slot group / symbol group basis.

[0245] For example, the UE may also determine the granularity of indication / reporting commonly for multiple (e.g., all) time slots / symbols / time slot groups / symbol groups.

[0246] At least one of the resource range in the frequency domain, the frequency-domain resource range, and the granularity of indication / reporting may be predefined in the specification or may be configured for the UE using higher-layer signaling (RRC / MAC CE).

[0247] The granularity of the indication / reporting may also be below the frequency-domain resource range of the indication / reporting.

[0248] For example, at least one of the request (command) for (desired) DL transmit power adjustment and the request for (desired) UL PSD range may also represent a value for a specific frequency resource. The specific frequency resource may also be, for example, wide band (e.g., Y sub-bands where Y is any number greater than or equal to 1).

[0249] For example, the UE may also determine the granularity of indication / reporting on a per sub-band basis.

[0250] For example, the UE may also determine the granularity of indication / reporting commonly for multiple (e.g., all) wide bands (e.g., Y sub-bands).

[0251] In the spatial domain, the UE may also perform at least one of common reporting for one or more associated beams or beam groups and reporting for each beam (group).

[0252] When reporting for each beam (group), the beam (group) may also be represented by an index (set) of a specific reference signal. The index of the specific reference signal may also be, for example, the SSB index / CSI-RS resource (set) index / SRS resource (set) index.

[0253] [Time-domain resource range]

[0254] Hereinafter, the range (unit) of the time-domain resources will be described.

[0255] For the UE, one or more time-domain resources may also be configured as the time-domain range for power adjustment reporting. The one or more time-domain resources may also be, for example, periodic / semi-persistent / aperiodic time-domain resources.

[0256] The time-domain range of the power adjustment reporting may also be represented by consecutive or non-consecutive time-domain resources (e.g., time slots / symbols) (in each period / cycle).

[0257] In addition, in the present disclosure, the power adjustment report / power adjustment indication may also include at least one of an indication for sending a power adjustment command from the base station (network) to the UE's DL, a report from the base station (network) to the UE related to a power adjustment request for the (desired) DL, and a report from the base station (network) to the UE related to a (desired) UL PSD range request.

[0258] The periodic / semi-persistent time domain resources as the time resource range of the power adjustment report may be either pre-specified in the specification or set for the UE using higher layer signaling (RRC / MAC CE) (Example 2-1-1A).

[0259] New higher layer parameters / RRC information elements for the power adjustment report may also be specified (e.g., PowerAdjustmentResource) (Example 2-1-1A-1). This RRC information element may also include a parameter for indicating the time resource of the power adjustment report.

[0260] In Example 2-1-1A-1, this parameter may also be, for example, at least one of a parameter representing the period, a parameter representing the start offset of each period, a parameter representing the length (in time slots / symbols) of the period within, and a parameter representing a list of time slots / symbols / slot groups / symbol groups for each period.

[0261] Figure 9 is a diagram showing an example of the RRC information element related to Example 2-1-1A-1. In Figure 9 the example shown, the RRC information element (PowerAdjustmentResource) for the power adjustment report is described.

[0262] In Figure 9 the example shown, in PowerAdjustmentResource, to set the time domain resource of the power adjustment report, it includes a parameter (slotList) representing a list of time slots and a parameter (periodicitySlotList) representing the period.

[0263] In addition, as the time resource of the power adjustment report, a specific time resource may also be used (Example 2-1-1A-2). This specific time resource may also be, for example, at least one of a CLI-RSSI (Received Signal Strength Indicator) / SRS-RSRP measurement resource and a CSI-RS / SRS resource.

[0264] In addition, a default time domain resource can also be defined / stipulated for power adjustment reporting (Example 2-1-1A-3). For example, the default time domain resource can also be at least one of the time resources (e.g., time slots / symbols) for SBFD in each period and the time resources (e.g., time slots / symbols) for non-SBFD.

[0265] In addition, the period can either be stipulated in the specification in advance or be set for the UE using high-layer signaling (RRC / MAC CE).

[0266] The aperiodic time domain resource as the time resource range for power adjustment reporting can either be stipulated in the specification in advance or be set for the UE using high-layer signaling (RRC / MAC CE) (Example 2-1-1B).

[0267] As the time resource for power adjustment reporting, a specific time resource can also be used (Example 2-1-1B-1). The specific time resource can also be, for example, an aperiodic CSI-RS / SRS resource.

[0268] In addition, a default time domain resource can also be defined / stipulated for power adjustment reporting (Example 2-1-1B-2). For example, the default time domain resource can also be represented by the offset after power adjustment reporting. The offset can also represent, for example, at least one of X consecutive time resources (e.g., time slots / symbols) for SBFD (in a certain time slot group / symbol group) and the time resources for non-SBFD.

[0269] [Time domain reporting granularity]

[0270] Hereinafter, the granularity of time domain reporting will be described.

[0271] The granularity of the reporting can also be below the range of the time domain resources of the reporting.

[0272] For example, when the granularity of the reporting is equal to the range of the time domain resources of the reporting, the reporting can also be performed for each range of the time domain resources. In addition, for example, when the granularity of the reporting is smaller than the range of the time domain resources of the reporting, the reporting can also be performed using smaller units (time units) included in the range of the time domain resources.

[0273] The granularity of the reporting can either be stipulated in the specification in advance or be set for the UE using high-layer signaling (RRC / MAC CE).

[0274] Within the continuous or discontinuous time domain resources (in a certain period / cycle) as the time resource range for power adjustment reporting described in the above description of the time domain resource range, the power adjustment reporting can also be set / stipulated / decided for the entire time domain resource.

[0275] In the continuous or discontinuous time-domain resources (in a certain period / cycle) that are described in the above description of the time-domain resource range and that are the time-resource range for the power adjustment report, the granularity of the power adjustment report can be set / stipulated / decided either for each symbol / slot / symbol group / slot group or for each set of (continuous) symbols / slots.

[0276] In the continuous or discontinuous time-domain resources (in a certain period / cycle) that are described in the above description of the time-domain resource range and that are the time-resource range for the power adjustment report, the granularity of the power adjustment report can also be set / stipulated / decided based on at least one of the time resources for SBFD (e.g., slot / symbol) and the time resources for non-SBFD (e.g., slot / symbol).

[0277] For example, the report on the time resources for SBFD (e.g., slot / symbol) and the report on the time resources for non-SBFD (e.g., slot / symbol) can also be set / stipulated / decided separately.

[0278] [Frequency-domain resource range]

[0279] Hereinafter, the range of the frequency-domain resources will be described.

[0280] For the UE, continuous or discontinuous frequency-domain resources can also be set as the frequency-domain resource range for the power adjustment report. The continuous or discontinuous frequency-domain resources can also be represented by, for example, one or more resource elements (REs) / resource blocks (RBs) / RB groups (RBGs) / subbands.

[0281] The frequency-domain resources for the power adjustment report can be either pre-stipulated in the specification or set for the UE using higher-layer signaling (RRC / MAC CE) (Example 2-2-1A).

[0282] Higher-layer parameters / new RRC information elements for the power adjustment report (e.g., PowerAdjustmentResource) can also be stipulated (Example 2-2-1A-1). This RRC information element can also contain a parameter for indicating the frequency resources for the power adjustment report.

[0283] In Example 2-2-1A-1, this parameter can, for example, also be at least one of a parameter representing the starting RB (for each subband), a parameter representing the ending RB (for each subband), a parameter representing the number of RBs / RBGs (for each subband), and a parameter representing a list / bitmap of one or more RBs / RBGs / subbands.

[0284] In addition, as the frequency resources for power adjustment reports, specific frequency resources (e.g., 2-2-1A-2) can also be used. Such specific frequency resources can, for example, also be at least one of the CLI-RSSI / SRS-RSRP measurement resources and the CSI-RS / SRS resources.

[0285] In addition, default frequency domain resources (e.g., 2-2-1A-3) can also be defined / stipulated for power adjustment reports. For example, such default frequency domain resources can also be at least one of specific DL / UL BWPs (e.g., the overall DL / UL BWP) and the DL / UL subbands in the symbols / slots for SBFD / non-SBFD.

[0286] [Frequency domain reporting granularity]

[0287] In the following, the granularity of frequency domain reports will be described.

[0288] The granularity of the report can also be below the resource range of the frequency domain of the report.

[0289] For example, when the granularity of the report is equal to the range of the frequency domain resources to be reported, reporting can be performed for each range of frequency domain resources. In addition, for example, when the granularity of the report is smaller than the range of the frequency domain resources to be reported, reporting can be performed using smaller units (frequency units) included in the range of the frequency domain resources.

[0290] The granularity of the report can either be stipulated in the specification in advance or be set for the UE using higher layer signaling (RRC / MAC CE).

[0291] Within the continuous or discontinuous frequency domain resources that are the frequency resource range for power adjustment reports as described in the above description of the frequency domain resource range, the power adjustment report can also be set / stipulated / decided for the entire frequency domain resources.

[0292] Within the continuous or discontinuous frequency domain resources that are the frequency resource range for power adjustment reports as described in the above description of the frequency domain resource range, the granularity of the power adjustment report can also be set / stipulated / decided for each RB / RBG / subband.

[0293] Within the continuous or discontinuous frequency domain resources that are the frequency resource range for power adjustment reports as described in the above description of the frequency domain resource range, the granularity of the power adjustment report can also be set / stipulated / decided based on at least one of the time resources for SBFD (e.g., time slots / symbols) and the time resources for non-SBFD (e.g., time slots / symbols).

[0294] For example, based on the report of the (overall) frequency resource in the time resource (e.g., time slot / symbol) for non-SBFD use and the sub-band level in the time resource (e.g., time slot / symbol) for SBFD use, the granularity of the power adjustment report is set / stipulated / decided.

[0295] <<Application Examples of Embodiment 2-0 and Embodiment 2-1>>

[0296] Hereinafter, specific examples of the contents included in the report in the case of applying the above Embodiment 2-0 and 2-1 will be described.

[0297] For the UE, time / frequency / spatial resources can also be set in the new RRC information element (e.g., PowerAdjustmentResource) and the existing resources (resource set).

[0298] The UE can also judge at least one of the granularity of the report and the range of the time / frequency / spatial resources of the report based on this setting, and derive the report.

[0299] This existing resource (resource set) can also be, for example, at least one of a CSI-RS resource (resource set), an SRS resource (resource set), and a CLI-RSSI / SRS-RSRP measurement resource.

[0300] This time / frequency resource can also be the time / frequency resource for the power adjustment report. This spatial resource can also be, for example, a beam.

[0301] The UE can also use one power adjustment report to report one or more resource (resource set) IDs representing the time / frequency resources for the power adjustment report.

[0302] This resource (resource set) ID can also be, for example, at least one of a power adjustment resource index, a CSI-RS resource (resource set) index, an SRS resource (resource set) index, and a CLI-RSSI / SRS-RSRP measurement resource index.

[0303] For each ID of the resource / resource set, reporting can be performed commonly for one or more associated beams / beam groups, or can be performed for each beam / beam group.

[0304] Regarding the judgment of the spatial resource (beam), the UE can also apply at least one of Option A and Option B shown below. In the present disclosure, the desired value can also mean, for example, at least one of the desired DL transmission power adjustment value and the desired UL PSD range value.

[0305] [Option A]

[0306] The UE can also report on a per-beam / beam-group basis. In other words, the value of a power adjustment report can also correspond to a beam / beam-group.

[0307] 〔Scenario A-1〕

[0308] The granularity of the report in the time domain can also be equal to the scope of the resources in the time domain. The granularity of the report in the frequency domain can also be equal to the scope of the resources in the frequency domain.

[0309] The UE can also report the expected value (e.g., at least one of the expected DL transmission power adjustment value and the expected UL PSD range value) corresponding to a beam (beam-group) for each beam (beam-group).

[0310] The number of beams (beam-groups) (denoted as k) can also be a number that is 0 or more and less than (or less than or equal to) the maximum number of reported beams (beam-groups) within a report.

[0311] Figure 10A It is a diagram showing an example of the power adjustment report related to Scenario A-1. In Figure 10A In the example shown, an example of the power adjustment report reported by the UE is shown.

[0312] In Figure 10A In the example shown, the expected values #1 to #n corresponding to each of the beams (beam-groups) #1 to #n are determined / reported for each time / frequency resource (resource set) ID.

[0313] 〔Scenario A-2〕

[0314] The granularity of the report in the time domain can also be equal to the scope of the resources in the time domain. The granularity of the report in the frequency domain can be less than the scope of the resources in the frequency domain.

[0315] The UE can also report the expected value (e.g., at least one of the expected DL transmission power adjustment value and the expected UL PSD range value) corresponding to a beam (beam-group) for each frequency resource (e.g., RB / RBG / sub-band) for each beam (beam-group).

[0316] The number of beams (beam-groups) (denoted as k) can also be a number that is 0 or more and less than the maximum number of reported beams (beam-groups) within a report (or less than or equal to that maximum number).

[0317] Figure 10B It is a diagram showing an example of the power adjustment report related to Scenario A-2. In Figure 10B In the example shown, an example of the power adjustment report reported by the UE is shown.

[0318] In Figure 10BIn the example shown, for each of the beam(s) #1 to #n, the expected value of the index of each sub-band is determined / reported according to each time / frequency resource (resource set) ID.

[0319] 〔Case A-3〕

[0320] The granularity of reporting in the time domain can also be smaller than the range of resources in the time domain. The granularity of reporting in the frequency domain can also be equal to the range of resources in the frequency domain.

[0321] The UE can also report, for each beam (beam group), the expected value (e.g., at least one of the expected value of the DL transmission power adjustment and the expected value of the UL PSD range) of each set of time resources (e.g., symbol / slot / symbol group / slot group) corresponding to one beam (beam group).

[0322] The number of beams (beam groups) (denoted as k) can also be a number that is 0 or more and less than (or less than or equal to) the maximum number of reported beams (beam groups) in one report.

[0323] Figure 11A is a diagram showing an example of the power adjustment report related to Case A-3. In Figure 11A In the example shown, an example of the power adjustment report reported by the UE is shown.

[0324] In Figure 11A In the example shown, for each of the beam(s) #1 to #n, the expected value of each set of time resources (symbol / slot (group)) can also be determined / reported according to each time / frequency resource (resource set) ID.

[0325] In addition, the UE can also report, for each beam (beam group), the expected value (e.g., at least one of the expected value of the DL transmission power adjustment and the expected value of the UL PSD range) of the time resources (e.g., symbol / slot) for non-SBFD and the expected value of the time resources (e.g., symbol / slot) for SBFD corresponding to one beam (beam group).

[0326] The number of beams (beam groups) (denoted as k) can also be a number that is 0 or more and less than (or less than or equal to) the maximum number of reported beams (beam groups) in one report.

[0327] Figure 11B is a diagram showing another example of the power adjustment report related to Case A-3. In Figure 11B In the example shown, an example of the power adjustment report reported by the UE is shown.

[0328] In Figure 11BIn the example shown, for each of the beam(s) #1 to #n, the desired value corresponding to each of the time resources for non - SBFD and the time resources for SBFD can also be determined / reported according to each time / frequency resource (resource set) ID.

[0329] 〔Case A - 4〕

[0330] The granularity of reporting in the time domain can also be smaller than the range of time resources. The granularity of reporting in the frequency domain can also be smaller than the range of frequency resources.

[0331] The UE can also report, for each beam (beam group), the desired value (e.g., at least one of the desired DL transmission power adjustment value and the desired UL PSD range value) corresponding to each set of each frequency resource (e.g., RB / RBG / sub - band) and time resource (e.g., symbol / slot / symbol group / slot group) for one beam (beam group).

[0332] The number of beams (beam groups) (denoted as k) can also be a number that is 0 or more and less than (or less than or equal to) the maximum number of reported beams (beam groups) within one report.

[0333] Figure 12A It is a diagram showing an example of the power adjustment report related to Case A - 4. In Figure 12A In the example shown, an example of the power adjustment report reported by the UE is shown.

[0334] In Figure 12A In the example shown, for each of the beam(s) #1 to #n, the desired value of each frequency resource (one of sub - bands #1 to #n) and each set of time resources (symbol / slot (group)) is determined / reported according to each time / frequency resource (resource set) ID.

[0335] In addition, the UE can also report, for each beam (beam group), the desired value (e.g., at least one of the desired DL transmission power adjustment value and the desired UL PSD range value) of the time resources for non - SBFD (e.g., symbol / slot) corresponding to one beam (beam group) and the desired value of the time resources for SBFD (e.g., symbol / slot).

[0336] The number of beams (beam groups) (denoted as k) can also be a number that is 0 or more and less than (or less than or equal to) the maximum number of reported beams (beam groups) within one report.

[0337] Figure 12B It is a diagram showing another example of the power adjustment report related to Case A - 4. InFigure 12B In the example shown, an example of a power adjustment report reported by the UE is shown.

[0338] In Figure 12B In the example shown, for each of beams (beam groups) #1 to #n, for each frequency resource (one of sub-bands #1 to #n), the desired value corresponding to each of the time resources for non-SBFD and the time resources for SBFD is determined / reported according to each time / frequency resource (resource set) ID.

[0339] [Option B]

[0340] The UE may also perform a common report for more than one associated beam / beam group. In other words, the value of a power adjustment report may also correspond to multiple beams / beam groups.

[0341] [Case B-1]

[0342] The granularity of the report in the time domain may also be equal to the range of the time domain resources. The granularity of the report in the frequency domain may also be equal to the range of the frequency domain resources.

[0343] The UE may also report the desired value (e.g., at least one of the desired DL transmission power adjustment value and the desired UL PSD range value) corresponding to multiple beams (beam groups).

[0344] Figure 13A It is a diagram showing an example of the power adjustment report related to Case B-1. In Figure 13A In the example shown, an example of a power adjustment report reported by the UE is shown.

[0345] In Figure 13A In the example shown, the desired value (#1) corresponding to multiple beam groups is determined / reported according to each time / frequency resource (resource set) ID.

[0347] The granularity of the report in the time domain may also be equal to the range of the time domain resources. The granularity of the report in the frequency domain may be less than the range of the frequency domain resources.

[0348] The UE may also report the desired value (e.g., at least one of the desired DL transmission power adjustment value and the desired UL PSD range value) corresponding to multiple beams (beam groups) for each frequency resource (e.g., RB / RBG / sub-band).

[0350] In Figure 13B the example shown, the expected value of the index of each sub-band can also be determined / reported per time / frequency resource (resource set) ID.

[0351] 〔Case B-3〕

[0352] The granularity of reporting in the time domain can also be smaller than the range of resources in the time domain. The granularity of reporting in the frequency domain can also be equal to the range of resources in the frequency domain.

[0353] The UE can also report the expected value (e.g., at least one of the expected DL transmission power adjustment value and the expected UL PSD range value) of each set of time resources (e.g., symbols / slots / symbol groups / slot groups) corresponding to multiple beams (beam groups).

[0354] Figure 14A is a diagram showing an example of the power adjustment report related to Case B-3. In Figure 14A the example shown, an example of the power adjustment report reported by the UE is shown.

[0355] In Figure 14A the example shown, the expected value of each set of time resources (symbols / slots (groups)) is determined / reported per time / frequency resource (resource set) ID.

[0356] In addition, the UE can also report the expected value (e.g., at least one of the expected DL transmission power adjustment value and the expected UL PSD range value) of the time resources (e.g., symbols / slots) for non-SBFD corresponding to multiple beams (beam groups) and the expected value of the time resources (e.g., symbols / slots) for SBFD.

[0358] In Figure 14B the example shown, the expected value corresponding to each of the time resources for non-SBFD and the time resources for SBFD is determined / reported per time / frequency resource (resource set) ID.

[0359] 〔Case B-4〕

[0360] The granularity of reporting in the time domain can also be smaller than the range of resources in the time domain. The granularity of reporting in the frequency domain can also be smaller than the range of resources in the frequency domain.

[0361] The UE may also report the expected values (e.g., at least one of the expected DL transmission power adjustment value and the expected UL PSD range value) corresponding to multiple beams (beam groups) for each set of each frequency resource (e.g., RB / RBG / sub-band) and time resource (e.g., symbol / slot / symbol group / slot group).

[0362] Figure 15A is a diagram showing an example of the power adjustment report related to Case B-4. In Figure 15A the example shown, an example of the power adjustment report reported by the UE is shown.

[0363] In Figure 15A the example shown, for each time / frequency resource (resource set) ID, the expected values for each frequency resource (one of sub-bands #1 to #n) and each set of time resources (symbol / slot (group)) (one of sets #1 to #m) are determined / reported.

[0364] In addition, the UE may also report the expected values (e.g., at least one of the expected DL transmission power adjustment value and the expected UL PSD range value) corresponding to multiple beams (beam groups) for each frequency resource (e.g., RB / RBG / sub-band) and the expected values for the time resources (e.g., symbol / slot) for non-SBFD and the time resources (e.g., symbol / slot) for SBFD.

[0365] Figure 15B is a diagram showing another example of the power adjustment report related to Case B-4. In Figure 15B the example shown, an example of the power adjustment report reported by the UE is shown.

[0366] In Figure 15B the example shown, for each frequency resource (one of sub-bands #1 to #n), the expected values corresponding to each of the time resources for non-SBFD and the time resources for SBFD are determined / reported for each time / frequency resource (resource set) ID.

[0367] According to the above Embodiments 2-0 and 2-1, the information related to power adjustment reported / requested by the UE can be appropriately defined.

[0368] 《Embodiment 2-2》

[0369] The information related to power adjustment reported / requested by the UE (e.g., at least one piece of information described in the above Embodiments 2-0 / 2-1) may also be transmitted using a specific UL channel / signal.

[0370] This specific UL channel can also be, for example, UCI (Option 2-2-1 below), or MAC CE / PUSCH PDU (Protocol Data Unit) (Option 2-2-2 below).

[0371] [Option 2-2-1]

[0372] The UE can also use UCI to send information related to power adjustment for reporting / requesting.

[0373] More than one (dedicated) PUCCH / PUSCH resource can also be set for reporting of this UCI.

[0374] This (each) PUCCH / PUSCH resource can also be a periodic / semi-persistent / aperiodic resource.

[0375] When this PUCCH / PUSCH resource is a semi-persistent / aperiodic resource, the UE can also be activated for this resource based on an indication of DCI / MAC CE.

[0376] As described in the above Embodiment 2-1, this (each) PUCCH / PUSCH resource can also be associated with more than one resource for power adjustment reporting.

[0377] For example, (as described in Example 2-1-1A-1 / Example 2-2-1A-1 in the above Embodiment 2-1) when a new RRC information element (for example, PowerAdjustmentResource) is used in the indication of time / frequency resources for power adjustment reporting, each PUCCH / PUSCH resource for power adjustment reporting can also be associated with more than one resource set by this new RRC information element (for example, PowerAdjustmentResource).

[0378] For example, when an existing resource (for example, at least one of the CLI-RSSI / SRS-RSRP measurement resources and CSI-RS / SRS resources described in Example 2-1-1A-2 / Example 2-2-1A-2 in the above Embodiment 2-1) is used in the indication of time / frequency resources for power adjustment reporting, each PUCCH / PUSCH resource for power adjustment reporting can also be associated with more than one of this existing resource.

[0379] [Option 2-2-2]

[0380] The UE can also use MAC CE / PUSCH PDU to send information related to power adjustment for reporting / requesting.

[0381] The timing of reporting in the UE may also depend on the installation of the UE.

[0382] The conditions related to the timing of reporting in the UE can be either pre-specified in the specification, or set for the UE using higher layer signaling (RRC / MAC CE), or notified to the UE using a combination of them.

[0383] The condition can also be at least one of the following:

[0384] · When a CLI / CSI measurement report in at least one of Layer 1 and Layer 3 is triggered.

[0385] · When measurement results of different CLIs are measured / reported.

[0386] · When the measured CLI is greater than a specific threshold.

[0387] · When the difference in measurement results of CSI is greater than a specific threshold.

[0388] According to the above Embodiment 2-2, the transmission of information related to power adjustment can be appropriately performed.

[0389] [Notification of Information to the UE]

[0390] The notification of any information from the above-described embodiment (from the network (NW) (e.g., from the base station (BS))) to the UE (in other words, the reception of any information from the BS in the UE) can also be performed using physical layer signaling (e.g., DCI), higher layer signaling (e.g., RRC signaling, MAC CE), specific signals / channels (e.g., PDCCH, PDSCH, reference signal), or a combination of them.

[0391] In the case where the above notification is performed via MAC CE, the MAC CE can also be identified by being included in the MAC sub-header with a new logical channel ID (LCID) not specified in the existing specification.

[0392] In the case where the above notification is performed via DCI, the above notification can also be performed via a specific field of the DCI, a radio network temporary identifier (RNTI) used in the scrambling of the cyclic redundancy check (CRC) bits assigned to the DCI, the format of the DCI, etc.

[0393] In addition, the notification of any information in the above-described embodiments to the UE can also be performed periodically, semi-persistently, or aperiodically.

[0396] In the case where the above notification is performed via MAC CE, the MAC CE can also be identified by being included in the MAC sub-header with a new LCID not defined in the existing specifications.

[0440] Hereinafter, the structure of a wireless communication system according to an embodiment of the present disclosure will be described. In this wireless communication system, any one or a combination of the wireless communication methods according to the above-described embodiments of the present disclosure is used for communication.

[0441] Figure 16This is a diagram showing an example of the schematic structure of a wireless communication system according to an embodiment. The wireless communication system 1 (which may also be abbreviated as system 1) may also be a system that implements communication using Long Term Evolution (LTE) standardized by the Third Generation Partnership Project (3GPP), the 5th generation mobile communication system New Radio (5G NR), and the like.

[0442] In addition, the wireless communication system 1 may also support dual connectivity (Multi-RAT Dual Connectivity (MR-DC)) between multiple Radio Access Technologies (RATs). MR-DC may include dual connectivity between LTE (Evolved Universal Terrestrial Radio Access (E-UTRA)) and NR (E-UTRA-NR Dual Connectivity (EN-DC)), dual connectivity between NR and LTE (NR-E-UTRA Dual Connectivity (NE-DC)), and the like.

[0443] In EN-DC, the base station (eNB) of LTE (E-UTRA) is the Master Node (MN), and the base station (gNB) of NR is the Secondary Node (SN). In NE-DC, the base station (gNB) of NR is the MN, and the base station (eNB) of LTE (E-UTRA) is the SN.

[0444] The wireless communication system 1 may also support dual connectivity between multiple base stations within the same RAT (for example, dual connectivity where both the MN and the SN are base stations (gNBs) of NR (NR-NR Dual Connectivity (NN-DC))).

[0445] The wireless communication system 1 may also include a base station 11 that forms a macro cell C1 with a relatively wide coverage area, and a base station 12 (12a - 12c) that is configured within the macro cell C1 and forms a small cell C2 that is narrower than the macro cell C1. The user terminal 20 may also be located within at least one cell. The configuration, quantity, etc. of each cell and the user terminal 20 are not limited to the manner shown in the figure. Hereinafter, without distinguishing between the base stations 11 and 12, they are collectively referred to as the base station 10.

[0446] The user terminal 20 may also be connected to at least one of the multiple base stations 10. The user terminal 20 may also utilize at least one of carrier aggregation (CA) and dual connectivity (DC) that uses multiple component carriers (CCs).

[0447] Each CC may also be included in at least one of a first frequency band (Frequency Range 1 (FR1)) and a second frequency band (Frequency Range 2 (FR2)). The macro cell C1 may also be included in FR1, and the small cell C2 may also be included in FR2. For example, FR1 may be a frequency band of 6 GHz or less (sub - 6 GHz), and FR2 may be a frequency band higher than 24 GHz (above - 24 GHz). Additionally, the frequency bands, definitions, etc. of FR1 and FR2 are not limited to these. For example, FR1 may correspond to a frequency band higher than FR2.

[0460] In the detection of the PDCCH, the Control Resource Set (CORESET) and the search space can also be used. The CORESET corresponds to the resource for searching for the DCI. The search space corresponds to the search area and search method of the PDCCH candidates. One CORESET can also be associated with one or more search spaces. The UE can also monitor the CORESET associated with a certain search space based on the search space setting.

[0461] One search space can also correspond to the PDCCH candidates equivalent to one or more aggregation levels. One or more search spaces can also be referred to as a search space set. In addition, the "search space", "search space set", "search space setting", "search space set setting", "CORESET", "CORESET setting", etc. in the present disclosure can also be rewritten with each other.

[0528] (Modification example)

[0529] In addition, the terms described in this disclosure and the terms necessary for understanding this disclosure may also be replaced with terms having the same or similar meanings. For example, a channel, a symbol, and a signal (signal or signaling) may also be rewritten with each other. In addition, a signal may also be a message. A reference signal can also be abbreviated as RS, and can also be referred to as a pilot, a pilot signal, etc. according to the applied standard. In addition, a component carrier (Component Carrier (CC)) may also be referred to as a cell, a frequency carrier, a carrier frequency, etc.

[0530] A radio frame may also be composed of one or more periods (frames) in the time domain. Each of the one or more periods (frames) constituting the radio frame may also be referred to as a subframe. Further, a subframe may also be composed of one or more time slots in the time domain. A subframe may also be a fixed time length (e.g., 1 ms) independent of the numerology.

[0531] Here, the numerology may also be a communication parameter applied in at least one of the transmission and reception of a certain signal or channel. For example, the numerology may also represent at least one of a subcarrier spacing (SubCarrier Spacing (SCS)), a bandwidth, a symbol length, a cyclic prefix length, a transmission time interval (Transmission Time Interval (TTI)), the number of symbols per TTI, a radio frame structure, a specific filtering process performed by a transmitter-receiver in the frequency domain, a specific windowing process performed by a transmitter-receiver in the time domain, etc.

[0532] A time slot may also be composed of one or more symbols (orthogonal frequency division multiplexing (Orthogonal Frequency Division Multiplexing (OFDM)) symbols, single carrier frequency division multiple access (Single Carrier Frequency Division Multiple Access (SC-FDMA)) symbols, etc.) in the time domain. In addition, a time slot may also be a time unit based on the numerology.

[0533] A time slot may also contain multiple mini-slots. Each mini-slot may also be composed of one or more symbols in the time domain. In addition, a mini-slot may also be referred to as a sub-slot. A mini-slot may also be composed of a smaller number of symbols than a time slot. A PDSCH (or PUSCH) transmitted in a time unit larger than a mini-slot may also be referred to as PDSCH (PUSCH) mapping type A. A PDSCH (or PUSCH) transmitted using a mini-slot may also be referred to as PDSCH (PUSCH) mapping type B.

[0534] A radio frame, subframe, time slot, mini time slot, and symbol all represent time units for transmitting signals. A radio frame, subframe, time slot, mini time slot, and symbol may also use their respective other names. Additionally, time units such as frames, subframes, time slots, mini time slots, and symbols in the present disclosure can also be rewritten with each other.

[0535] For example, a subframe can also be referred to as a TTI, multiple consecutive subframes can also be referred to as a TTI, a time slot or a mini time slot can also be referred to as a TTI. That is, at least one of a subframe and a TTI can be a subframe (1 ms) in existing LTE, can also be a period shorter than 1 ms (e.g., 1 - 13 symbols), and can also be a period longer than 1 ms. Additionally, the unit representing a TTI may not be referred to as a subframe, but as a time slot, mini time slot, etc.

[0536] Here, a TTI, for example, refers to the minimum time unit for scheduling in wireless communication. For example, in an LTE system, a base station performs scheduling to allocate radio resources (frequency bandwidth, transmission power, etc. that can be used in each user terminal) in units of TTI for each user terminal. Additionally, the definition of a TTI is not limited to this.

[0537] A TTI can also be a transmission time unit for data packets (transport blocks), code blocks, codewords, etc. that have undergone channel coding, and can also become a processing unit for scheduling, link adaptation, etc. Additionally, when a TTI is given, the time interval (e.g., the number of symbols) in which a transport block, code block, codeword, etc. is actually mapped can also be shorter than the TTI.

[0538] Additionally, when a time slot or a mini time slot is referred to as a TTI, one or more TTIs (i.e., one or more time slots or one or more mini time slots) can also become the minimum time unit for scheduling. Furthermore, the number of time slots (mini time slots) constituting the minimum time unit of this scheduling can also be controlled.

[0539] A TTI having a time length of 1 ms can also be referred to as a normal TTI (TTI in 3GPP Rel.8 - 12), standard TTI, long TTI, normal subframe, standard subframe, long subframe, time slot, etc. A TTI shorter than a normal TTI can also be referred to as a shortened TTI, short TTI, partial TTI (partial or fractional TTI), shortened subframe, short subframe, mini time slot, sub - time slot, time slot, etc.

[0540] Additionally, a long TTI (e.g., a normal TTI, subframe, etc.) can also be rewritten as a TTI having a time length exceeding 1 ms, and a short TTI (e.g., a shortened TTI, etc.) can also be rewritten as a TTI having a TTI length less than that of the long TTI and not less than 1 ms.

[0541] A resource block (RB) is a resource allocation unit in the time domain and the frequency domain, and may also include one or more consecutive subcarriers (subcarriers) in the frequency domain. The number of subcarriers included in an RB may also be the same regardless of the parameter set, for example, it may also be 12. The number of subcarriers included in an RB may also be determined based on the parameter set.

[0542] In addition, an RB may also include one or more symbols in the time domain, and may also be the length of a time slot, a mini-slot, a subframe, or a TTI. A TTI, a subframe, etc. may also be composed of one or more resource blocks respectively.

[0543] In addition, one or more RBs may also be referred to as a physical resource block (PRB), a sub-carrier group (SCG), a resource element group (REG), a PRB pair, an RB pair, etc.

[0544] In addition, a resource block may also be composed of one or more resource elements (REs). For example, one RE may also be a radio resource area of a subcarrier and a symbol.

[0545] A bandwidth part (BWP) (which may also be referred to as a partial bandwidth, etc.) may also represent a subset of consecutive common RBs (common resource blocks) used for a certain parameter set in a certain carrier. Here, the common RBs may also be determined by the index of the RBs based on the common reference point of the carrier. A PRB may also be defined in a certain BWP and numbered additionally within that BWP.

[0546] A UL BWP (BWP for UL) and a DL BWP (BWP for DL) may also be included in a BWP. For a UE, one or more BWPs may also be set within one carrier.

[0547] At least one of the set BWPs may also be activated, and the UE may not assume to transmit and receive specific signals / channels outside the activated BWP. In addition, "cell", "carrier", etc. in the present disclosure may also be rewritten as "BWP".

[0548] In addition, the structures such as the above-mentioned radio frames, subframes, time slots, mini time slots, and symbols are merely illustrative. For example, the number of subframes included in a radio frame, the number of time slots in each subframe or radio frame, the number of mini time slots included in a time slot, the symbols included in a time slot or mini time slot, the number of RBs, the number of subcarriers included in an RB, and the number of symbols, symbol length, cyclic prefix (CP) length, etc. within a TTI can be changed in various ways.

For example, radio resources can also be indicated by a specific index.

[0550] In this disclosure, the names used for parameters, etc. are not restrictive names in all aspects. Furthermore, mathematical expressions, etc. using these parameters can also be different from those explicitly disclosed in this disclosure. Various channels (PUCCH, PDCCH, etc.) and information elements can be identified by any suitable name. Therefore, the various names assigned to these various channels and information elements are not restrictive names in all aspects.

[0551] The information, signals, etc. described in this disclosure can also be represented using any one of various different technologies. For example, data, instructions, commands, information, signals, bits, symbols, chips, etc. that may be mentioned throughout the above description can also be represented by voltage, current, electromagnetic waves, magnetic fields or magnetic particles, optical fields or photons, or any combination thereof.

[0552] In addition, information, signals, etc. can be output in at least one of the following directions: from a higher layer to a lower layer, and from a lower layer to a higher layer. Information, signals, etc. can also be input and output via multiple network nodes.

[0553] The input and output information, signals, etc. can be stored in a specific location (e.g., a memory), or can be managed using a management table. The input and output information, signals, etc. can be overwritten, updated, or appended. The output information, signals, etc. can also be deleted. The input information, signals, etc. can also be sent to other devices.

[0554] The notification of information is not limited to the manners / embodiments described in the present disclosure, and other methods may also be used. For example, the notification of information in the present disclosure may also be implemented through physical layer signaling (e.g., downlink control information (Downlink Control Information (DCI)), uplink control information (Uplink Control Information (UCI))), higher layer signaling (e.g., Radio Resource Control (RRC) signaling, broadcast information (Master Information Block (MIB), System Information Block (SIB), etc.), Medium Access Control (MAC) signaling), other signals, or combinations thereof.

[0555] In addition, physical layer signaling may also be referred to as Layer 1 / Layer 2 (L1 / L2) control information (L1 / L2 control signal), L1 control information (L1 control signal), etc. Furthermore, RRC signaling may also be referred to as an RRC message, and may also be, for example, an RRC Connection Setup message, an RRC Connection Reconfiguration (RRC Connection Re - setting (RRCConnection Reconfiguration)) message, etc. In addition, MAC signaling may be notified, for example, using a MAC Control Element (MACControl Element (CE)).

[0556] In addition, the notification of specific information (e.g., the notification of "is X") is not limited to explicit notification, and may also be performed implicitly (e.g., by not performing the notification of the specific information, or by the notification of other information).

[0557] The determination may be made by a value represented by one bit (0 or 1), may also be made by a true - false value (boolean value) represented by true or false, and may also be made by a numerical comparison (e.g., comparison with a specific value).

[0558] Software, whether referred to as software, firmware, middleware, micro-code, hardware description language, or by any other name, shall be construed broadly to mean instructions, instruction sets, code, code segments, program code, programs, sub-programs, software modules, applications, software applications, software packages, routines, sub-routines, objects, executable files, threads of execution, procedures, functions, etc.

[0559] In addition, software, instructions, information, etc. can also be sent and received via a transmission medium. For example, in the case of sending software from a website, server, or other remote source using at least one of wired technologies (coaxial cable, fiber optic cable, twisted pair, Digital Subscriber Line (DSL), etc.) and wireless technologies (infrared, microwave, etc.), at least one of these wired and wireless technologies is included in the definition of the transmission medium.

There are also cases where base stations are referred to by terms such as macro cell, small cell, femto cell, pico cell, etc.

[0563] A base station can accommodate one or more (e.g., three) cells. When a base station accommodates multiple cells, the entire coverage area of the base station can be divided into multiple smaller areas, and each smaller area can also be provided with communication services by a base station subsystem (e.g., a small indoor base station (Remote Radio Head (RRH))). Terms such as "cell" or "sector" refer to a part or the whole of the coverage area of at least one of the base station and the base station subsystem that provides communication services within that coverage range.

[0564] In the present disclosure, the situation where a base station sends information to a terminal can also be rewritten as the base station instructing the terminal to perform control / operation based on that information.

[0565] In the present disclosure, terms such as "Mobile Station (MS)", "user terminal", "user device (User Equipment (UE))", "terminal" can be used interchangeably.

[0566] There are also cases where mobile stations are referred to by terms such as subscriber station, mobile unit, subscriber unit, radio unit, remote unit, mobile device, wireless device, wireless communication device, remote device, mobile subscriber station, access terminal, mobile terminal, wireless terminal, remote terminal, hand set, user agent, mobile client, client, or several other appropriate terms.

In addition, at least one of the base station and the mobile station also includes a device that does not necessarily move during communication operations. For example, at least one of the base station and the mobile station can also be an Internet of Things (IoT) device such as a sensor.

The vehicle 40 includes a drive unit 41, a steering unit 42, an accelerator pedal 43, a brake pedal 44, a shift lever 45, left and right front wheels 46, left and right rear wheels 47, an axle 48, an electronic control unit 49, various sensors (including a current sensor 50, a rotation speed sensor 51, a pressure sensor 52, a vehicle speed sensor 53, an acceleration sensor 54, an accelerator pedal sensor 55, a brake pedal sensor 56, a shift lever sensor 57, and an object detection sensor 58), an information service unit 59, and a communication module 60.

[0571] The drive unit 41 is constituted by, for example, at least one of an engine, a motor, and a hybrid of an engine and a motor. The steering unit 42 is configured to include at least a steering wheel (also referred to as a handlebar), and steers at least one of the front wheels 46 and the rear wheels 47 based on the operation of the steering wheel operated by the user.

[0572] The electronic control unit 49 is composed of a microprocessor 61, memories (ROM, RAM) 62, and communication ports (e.g., input / output (I / O) ports) 63. Signals from various sensors 50 - 58 provided in the vehicle are input into the electronic control unit 49. The electronic control unit 49 may also be referred to as an electronic control unit (Electronic Control Unit (ECU)).

[0573] As signals from various sensors 50 - 58, there are current signals from the current sensor 50 that senses the current of the motor, rotational speed signals of the front wheels 46 / rear wheels 47 obtained by the rotational speed sensor 51, air pressure signals of the front wheels 46 / rear wheels 47 obtained by the air pressure sensor 52, vehicle speed signals obtained by the vehicle speed sensor 53, acceleration signals obtained by the acceleration sensor 54, depression amount signals of the accelerator pedal 43 obtained by the accelerator pedal sensor 55, depression amount signals of the brake pedal 44 obtained by the brake pedal sensor 56, operation signals of the shift lever 45 obtained by the shift lever sensor 57, detection signals for detecting obstacles, vehicles, pedestrians, etc. obtained by the object detection sensor 58, and so on.

[0574] The information service unit 59 is composed of various devices such as a navigation system, an audio system, speakers, a display, a television, and a radio that provide (output) various types of information such as driving information, traffic information, and entertainment information, and one or more ECUs that control these devices. The information service unit 59 uses the information obtained from an external device via a communication module 60 or the like to provide various types of information / services (e.g., multimedia information / multimedia services) to the occupants of the vehicle 40.

[0575] The information service unit 59 may include input devices (e.g., keyboards, mice, microphones, switches, buttons, sensors, touch panels, etc.) that accept input from the outside, or may include output devices (e.g., displays, speakers, LED lights, touch panels, etc.) that perform output to the outside.

[0576] The driving assistance system unit 64 is composed of a millimeter-wave radar, a Light Detection and Ranging (LiDAR), a camera, a locator (such as a Global Navigation Satellite System (GNSS), etc.), map information (such as a High Definition (HD) map, an Autonomous Vehicle (AV) map, etc.), a gyroscope system (such as an inertial measurement device (Inertial Measurement Unit (IMU)), an inertial navigation device (Inertial Navigation System (INS)), etc.), an Artificial Intelligence (AI) chip, an AI processor, and various devices that provide functions for preventing accidents in advance or reducing the driver's driving burden, as well as one or more ECUs that control these devices. In addition, the driving assistance system unit 64 transmits and receives various information via the communication module 60 to implement the driving assistance function or the autonomous driving function.

[0577] The communication module 60 can communicate with the microprocessor 61 and the structural elements of the vehicle 40 via the communication port 63. For example, the communication module 60 transmits and receives data (information) via the communication port 63 between the driving unit 41, the steering unit 42, the accelerator pedal 43, the brake pedal 44, the shift lever 45, the left and right front wheels 46, the left and right rear wheels 47, the axle 48, the microprocessor 61 and the memory (ROM, RAM) 62 in the electronic control unit 49, and various sensors 50 - 58 provided in the vehicle 40.

[0578] The communication module 60 can be controlled by the microprocessor 61 of the electronic control unit 49 and is a communication device capable of communicating with external devices. For example, various information is transmitted and received via wireless communication with external devices. The communication module 60 can be inside and outside the electronic control unit 49. The external device can also be, for example, the above-mentioned base station 10, user terminal 20, etc. In addition, the communication module 60 can also be, for example, at least one of the above-mentioned base station 10 and user terminal 20 (and can also function as at least one of the base station 10 and user terminal 20).

[0579] The communication module 60 can also transmit at least one of the following to an external device via wireless communication: the signals from the various sensors 50-58 input to the electronic control unit 49, the information obtained based on the signals, and the information based on the input from the external (user) obtained via the information service unit 59. The electronic control unit 49, the various sensors 50-58, the information service unit 59, etc. can also be referred to as an input unit that accepts input. For example, the PUSCH transmitted via the communication module 60 can also include the information based on the above input.

[0580] The communication module 60 receives various information (traffic information, traffic light information, inter-vehicle information, etc.) transmitted from an external device and displays it on the information service unit 59 provided in the vehicle. The information service unit 59 can also be referred to as an output unit that outputs information (for example, the information output to devices such as a display and a speaker based on the PDSCH received via the communication module 60 (or the data / information decoded according to the PDSCH)).

[0581] In addition, the communication module 60 stores the various information received from the external device in the memory 62 that can be utilized by the microprocessor 61. Based on the information stored in the memory 62, the microprocessor 61 can also control the drive unit 41, the steering unit 42, the accelerator pedal 43, the brake pedal 44, the shift lever 45, the left and right front wheels 46, the left and right rear wheels 47, the axle 48, the various sensors 50-58, etc. provided in the vehicle 40.

[0582] In addition, the base station in the present disclosure can also be rewritten as a user terminal. For example, for a structure in which the communication between the base station and the user terminal is replaced by the communication between multiple user terminals (for example, it can also be referred to as Device-to-Device (D2D), Vehicle-to-Everything (V2X), etc.), the various aspects / embodiments of the present disclosure can also be applied. In this case, it can also be configured such that the user terminal 20 has the functions of the above base station 10. In addition, terms such as "uplink" and "downlink" can also be rewritten as terms corresponding to inter-terminal communication (for example, "sidelink"). For example, the uplink channel, the downlink channel, etc. can also be rewritten as the sidelink channel.

[0583] Similarly, the user terminal in the present disclosure can also be rewritten as a base station. In this case, it can also be configured such that the base station 10 has the functions of the above user terminal 20.

[0584] In the present disclosure, actions performed by a base station may sometimes be performed by its upper node depending on circumstances. Apparently, in a network including one or more network nodes having a base station, various operations performed for communication with a terminal may be performed by the base station, one or more network nodes other than the base station (for example, considering a Mobility Management Entity (MME), a Serving-Gateway (S-GW), etc., but not limited to these), or a combination thereof.

[0585] Each mode / embodiment described in the present disclosure may be used alone, in combination, or switched during execution. In addition, the processing procedures, timings, flowcharts, etc. of each mode / embodiment described in the present disclosure may be rearranged as long as there is no contradiction. For example, regarding the methods described in the present disclosure, elements of various steps are presented in an exemplary order, but are not limited to the specific order presented.

[0586] Each mode / embodiment described in the present disclosure can also be applied to Long Term Evolution (LTE), LTE-Advanced (LTE-A), LTE-Beyond (LTE-B), SUPER 3G, IMT-Advanced, 4th generation mobile communication system (4G), 5th generation mobile communication system (5G), 6th generation mobile communication system (6G), xth generation mobile communication system (xG (x is an integer or a decimal, for example)), Future Radio Access (FRA), New-Radio Access Technology (RAT), New Radio (NR), New radio access (NX), Future generation radio access (FX), Global System for Mobile communications (GSM (registered trademark)), CDMA2000, Ultra Mobile Broadband (UMB), IEEE 802.11 (Wi-Fi (registered trademark)), IEEE 802.16 (WiMAX (registered trademark)), IEEE 802.20, Ultra-WideBand (UWB), Bluetooth (registered trademark), systems using other appropriate wireless communication methods, next-generation systems extended, modified, generated, or defined based on them, etc. In addition, multiple systems can also be combined (for example, a combination of LTE or LTE-A and 5G) for application.

[0587] The description "based on" used in the present disclosure, unless specifically stated otherwise, does not mean "only based on". In other words, the description "based on" means both "only based on" and "at least based on".

[0588] Any reference to an element using designations such as "first", "second", etc. used in this disclosure does not fully define the quantity or order of these elements. These designations can be used in this disclosure as a convenient method for distinguishing between more than two elements. Therefore, the reference to the first and second elements does not mean that only two elements can be employed, or that the first element must in some form take precedence over the second element.

[0589] The term "determining" as used in this disclosure encompasses diverse actions in some cases. For example, "determining" can also be a case where judging, calculating, computing, processing, deriving, investigating, looking up (searching, inquiring) (such as searching in a table, database, or other data structure), ascertaining, etc. are regarded as performing "determining".

[0590] In addition, "determining" can also be a case where receiving (e.g., receiving information), transmitting (e.g., transmitting information), input, output, accessing (e.g., accessing data in a memory), etc. are regarded as performing "determining".

[0591] Moreover, "determining" can also be a case where resolving, selecting, choosing, establishing, comparing, etc. are regarded as performing "determining". That is, "determining" can also be a case where some actions are regarded as performing "determining".

[0592] In addition, "determining" can also be rewritten as "assuming", "expecting", "considering", etc.

[0593] The "maximum transmit power" described in this disclosure can either mean the maximum value of the transmit power, or the nominal UE maximum transmit power, or the rated UE maximum transmit power.

[0594] As used in this disclosure, the terms "connected" and "coupled" and all variations thereof mean all direct or indirect connections or couplings between two or more elements, and can include the situation where there is one or more intermediate elements between the two elements that are "connected" or "coupled" to each other. The coupling or connection between elements can be physical, logical, or a combination thereof. For example, "connected" can also be rewritten as "access".

[0595] In this disclosure, when two elements are connected, it is possible to consider that they are "connected" or "coupled" to each other by using one or more wires, cables, printed electrical connections, etc., and as several non-limiting and non-inclusive examples, electromagnetic energy having wavelengths in the radio frequency domain, microwave region, optical (both visible and invisible) region, etc., is used to "connect" or "couple" them to each other.

[0596] In this disclosure, the term "A is different from B" can also mean "A and B are different from each other". Additionally, this term can also mean "A and B are each different from C". Terms such as "separated" and "coupled" can also be interpreted in the same way as "different".

[0597] When the terms "include", "including", and their variations are used in this disclosure, these terms, like the term "comprising", have an inclusive meaning. Furthermore, the term "or" used in this disclosure does not mean exclusive or.

[0598] In this disclosure, for example, in cases where articles are added through translation such as a, an, and the in English, this disclosure can also include the situation where the nouns following these articles are in the plural form.

[0599] In this disclosure, terms such as "below", "less than", "above", "more than", "equal" can also be rewritten with each other. In addition, in this disclosure, terms meaning "good", "bad", "big", "small", "high", "low", "early", "late", "wide", "narrow", etc., are not limited to the positive, comparative, and superlative degrees and can also be rewritten with each other.
