Implementation of the invention

(TCI, spatial relationship, QCL)

NR is designed to control in the UE the receive processing (e.g., at least one of receive, demapping, demodulation, and decoding) and the processing for transmission (e.g., at least one of transmission, mapping, precoding, modulation, and coding) at least at least one of a signal and a channel (which may be referred to as "signal/channel"; similarly, in the present disclosure, an expression of the form "A/B" can be interpreted as "at least one of A and B") based on the state of the transmission configuration indicator ( TCI states).

The specified TCI state may be the state used for the downlink signal/channel. The state that corresponds to the TCI state used for the uplink signal/channel may be expressed as a spatial relationship.

The TCI state is information related to signal/channel Quasi-Co-Location (QCL), and may also be called a reception spatial parameter, spatial relationship information, or the like. The TCI state of a UE may be set for each channel or for each signal.

QCL is a measure of the statistical properties of a signal/channel. For example, having a QCL relationship of a signal/channel with another signal/channel may mean that for so many different signals/channels, there is reason to assume that at least one of Doppler shift, Doppler spread, average delay, delay distribution, and spatial parameter is equal (e.g., spatial reception parameter (spatial parameter Rx)) (may mean that quasi-proximity occurs with respect to at least one of these properties).

Note that said spatial receive parameter may correspond to a receive beam of the UE (eg, an analog receive beam), and this beam may be determined based on the spatial QCL. QCL (or at least one element in a QCL relationship) in the present disclosure can be interpreted as a spatial QCL (English spatial QCL, sQCL).

Different types of QCLs can be defined. For example, four types of QCLs (types A-D) may be provided, differing in which parameter(s, parameter set(s)) may be assumed to be the same, and this parameter(s), which may be referred to as QCL parameter(s), are described as follows:

- Type A QCL: Doppler shift, Doppler broadening, average delay and delay distribution;

- type B QCL: Doppler shift and Doppler broadening;

- type C QCL: Doppler shift and average delay;

- type D QCL: spatial receive parameter.

Types A-C may correspond to QCL information related to timing processing in at least one of time and frequency, and type D can correspond to QCL information related to beam steering.

The UE's assumption that a given Control Resource Set (CORESET), channel, or reference is in a particular QCL relationship (e.g., Type D QCL) with another CORESET, channel, or reference may be referred to as a QCL assumption.

The UE is configured to determine at least one of a transmit path (Tx path) and a receive path (Rx path) of a signal/channel based on the TCI state or QCL assumption of that signal/channel.

This TCI state can be, for example, information related to the QCL between the target channel (or reference signal (eng. Reference Signal, RS) for this channel) and another signal (for example, another downlink reference signal (eng. Downlink Reference Signal, DL). -RS)). The state of the TCI may be specified (indicated) by upper layer signaling, physical layer signaling, or a combination of these signaling types.

In the present disclosure, said upper layer signaling may be, for example, one of Radio Resource Control (RRC) layer signaling, Media Access Layer (MAC) signaling, broadcast information, and the like, or combinations of the above.

MAC layer signaling can use, for example, a MAC layer control element (MAC CE), a MAC layer Protocol Data Unit (PDU), or the like. , master information block (MIB), system information block (System Information Block, SIB), minimum system information (remaining minimum system information, eng. Remaining Minimum System Information, RMSI), other system information ( English Other System Information, OSI) or the like.

Said physical layer signaling may be, for example, downstream control information (DCI).

It should be appreciated that the channel/signal considered as the target for the TCI state may be referred to as the target channel/reference signal or simply the target, and the other signal described above may be referred to as the base reference signal or simply the base.

The channel for which the TCI state is set (indicated) may be, for example, at least one of a downlink common channel (Physical Downlink Shared Channel (PDSCH)), a downlink control channel (physical downlink control channel (Physical Downlink Control Channel, PDCCH)), uplink common channel (Physical Uplink Shared Channel, PUSCH) and uplink control channel (Physical Uplink Control Channel, PUCCH) ).

The reference signal (Downlink Reference Signal (DL-RS)), having a QCL relationship with the specified channel, can be, for example, at least one of the synchronization signal block (Eng. Synchronization Signal Block, SSB), reference a channel state information signal (CSI-RS) and a reference signal for measurement (Sounding Reference Signal (SRS)). Alternatively, the DL-RS signal can be a CSI-RS used for tracking (also called a Tracking Reference Signal (TRS)), or a reference signal used to find QCL (also called QRS).

SSB is a signal block containing at least one of a Primary Synchronization Signal (PSS), a Secondary Synchronization Signal (SSS) and a broadcast channel (Physical Broadcast Channel). , Strategic Missile Forces)). An SSB block may be referred to as an SS/PBCH block.

The TCI state information element defined using upper layer signaling (the RRC layer "TCI-state 1E" element) may contain one or more QCL information items ("QCL-Info"). Said QCL information may contain at least one of information related to a DL-RS having a QCL relationship (DL-RS relationship information) and information indicating a QCL type (QCL type information). Said DL-RS relationship information may include, for example, information such as a DL-RS index (for example, an SSB index or Non-Zero Power CSI-RS CSI-RS resource identifier, NZP CSI-RS ), the index of the cell in which the specified reference signal is located, and the index of the Bandwidth Part (BWP) in which the specified reference signal is located.

<TCI Status for PDCCH>

The QCL information between a given DL-RS and a PDCCH (or a DMRS antenna port related to a given PDCCH) may be referred to as a TCI state for the PDCCH or the like.

The UE is configured to determine the TCI state for that UE-specific PDCCH (CORESET) based on the upper layer signaling. For example, by signaling the RRC layer (ControlResourcezSet information element), the UE can be set to one or multiple (K) TCI states per CORESET.

For each CORESET, one or more TCI states can be activated by the MAC CE. This MAC CE may be referred to as the UE-specific TCI Status Flag MAC CE for the PDCCH. The UE may monitor CORESET based on the active state of the TCI corresponding to the specified CORESET.

<TCI Status for PDSCH>

The QCL information between a PDSCH (or a DMRS antenna port related to that PDSCH) and a given DL-RS may be referred to as a TCI state for the PDSCH or the like.

The UE may be notified of M (M ≥ 1) PDSCH TCI states (configured using M PDSCH QCL information units) via upper layer signaling. It should be appreciated that the number M of TCI states assigned to a UE may be limited by at least one of the UE's capability and the QCL type.

The DCI used for scheduling a PDSCH may contain a predetermined field indicating the TCI state for that PDSCH (also called, for example, a TCI field, a TCI state field, or the like). The specified DCI may be used for PDSCH scheduling in a single cell, and may be referred to as downstream DCI, downstream assignment, 1_0 format DCI, 1_1 format DCI, or the like, for example.

The inclusion or non-inclusion of the TCI field in the DCI may be controlled by information transmitted to the UE from the base station. This information may be information indicating the presence or absence of a TCI field in the DCI (eg, TCI presence information, TCI presence information in the DCI, or an upper layer parameter "TCI-PresentInDCI"). This information may be set for the UE, for example, by upper layer signaling.

In the case where more than eight types of TCI states are specified for the UE, the use of the MAC CE allows eight or fewer types of TCI states to be enabled (or specified). Such a MAC CE may be referred to as a UE-specific PDSCH TCI state activation/deactivation MAC CE. The value of the TCI field in the DCI may indicate one of the TCI states activated by this MAC CE.

In the case where the UE is configured with the TCI presence information set for the CORESET scheduling the given PDSCH (the CORESET used for transmitting the PDCCH scheduling the given PDSCH) to true, the UE may consider that in the DCI format 1_1 of the PDCCH being transmitted the specified CORESET contains the TCI field.

In the case where no TCI presence information is specified for the CORESET scheduling the PDSCH, or the PDSCH is scheduled by the DCI format 1_0, if the time offset between the reception of the downstream DCI (the DCI scheduling the PDSCH) and the reception of the PDSCH corresponding to the specified DCI is greater than or equal to the threshold value, then in order to determine the QCL of the PDSCH antenna port, the UE may consider that the TCI state or QCL guess for this PDSCH is identical to the TCI state or QCL guess used for the CORESET that was used to transmit the PDCCH scheduling this PDSCH,

In the case where the TCI presence information is set to true, and when the TCI field in the DCI on the scheduling (given PDSCH) elementary carrier (FC) indicates the activated state of TCI in the specified scheduled FC or downlink BWP, and the PDSCH is scheduled by the DCI format 1_1, the UE may use TCI to determine the QCL of the antenna port of a given PDSCH according to the value of the TCI field in the PDCCH containing the specified DCI and detected. In the case where the time offset between the reception of the downstream DCI (scheduled PDSCH) and the PDSCH corresponding to the specified DCI (the PDSCH scheduled by the specified DCI) is greater than or equal to a threshold value, the UE may assume that the DM-RS port of the PDSCH in the serving cell has QCL relationship to a reference signal in the TCI state for the QCL type parameter given by the TCI state indicated.

In the case where the UE is configured to use a single-slot PDSCH, the TCI state that is indicated may be based on the activated TCI state in the slot containing this scheduled PDSCH. In the case where the UE is configured to use multi-slot PDSCHs, the TCI state that is indicated may be based on the activated TCI state in the first slot containing the scheduled PDSCH, and the UE may assume that the TCI state that is indicated is identical in all slots containing this scheduled PDSCH. In the case where the UE is configured to use a CORESET associated with a search space specified for Cross-Carrier Scheduling, the UE is configured using TCI presence information that has the specified CORESET set to true, and in when at least one of the TCI states specified for the serving cell scheduled by the specified search space set contains a type D QCL, the UE may assume that the time offset between the detected PDCCH and the PDSCH corresponding to the specified PDCCH is greater than or equal to a threshold .

In the connected mode at the RRC layer, both in the case where the TCI information in the DCI (the upstream parameter "TCI-PresentlnDCI") is set to true, and in the case where the TCI information in the DCI is not set, in the case , when the time offset between the reception of the downstream DCI (DCI scheduling PDSCH) and the corresponding PDSCH (PDSCH scheduled by the specified DCI) is less than a threshold, the UE may assume that the DM-RS port of the specified PDSCH in the serving cell has a QCL relationship with the reference signal on the QCL parameter used to indicate the QCL of the PDCCH of the CORESET associated with the search space being monitored, where one or more CORESETs in the active BWP in the serving cell have the lowest (minimum) CORESET-ID in the latest (most new) slot monitored by the specified UE. This reference signal may be referred to as the standard TCI state of the PDSCH.

The specified time offset between the reception of the downlink DCI and the reception of the PDSCH corresponding to the specified DCI may be referred to as a scheduling offset.

The above-described threshold may be called a QSL time duration, "timeDurationForQCL", a threshold, a threshold for an offset between a DCI indicating a TCI state and a PDSCH scheduled by said DCI, "Threshold-Sched-Offset", "timeDurationForQCL", an offset threshold. when scheduling, a scheduling-related offset threshold, and the like.

The scheduling offset threshold may be determined, for example, based on the capability of the UE, or based on the delay required to decode the PDCCH and change beam. The scheduling offset threshold information may be set from the base station by upper layer signaling, or may be transmitted from the UE to the base station.

For example, the UE may assume that the DMRS port of the above-described PDSCH is quasi-close to the DL-RS based on the TCI state that is enabled for the CORESET corresponding to the lowest CORESET-ID described above. Said latest slot may be, for example, the slot in which the DCI scheduling the above-described PDSCH is received.

Note that the specified CORESET-ID may be an identifier specified by the "ControlResourceSet" element of the RRC layer information (identifier for identifying the CORESET).

<Spatial relationship for PUCCH>

Parameters used for PUCCH transmission (PUCCH configuration information, PUCCH-Config) can be set for the UE by higher layer signaling (eg, Radio Resource Control (RRC) layer signaling). Said PUCCH configuration information may be set for each partial band (eg, uplink frequency band (BWP) portion on some carrier (also called a cell, elementary carrier (EC) or the like).

The PUCCH configuration information may comprise a list of PUCCH resource set information (eg, PUCCH-ResourceSet) and a list of PUCCH spatial relationship information (eg, PUCCH-SpatialRelationInfo).

Said PUCCH resource set information may comprise a list (eg, resourceList) of PUCCH resource indices (identifiers, eg, PUCCH-ResourceId).

In the case where the UE does not have PUCCH resource specific configuration information (eg, PUCCH resource specific configuration) that is signaled by the PUCCH resource set information in the PUCCH configuration information (before setting at the RRC layer), the UE may determine the specified PUCCH resource set on based on parameters (eg, pucch-ResourceCommon) in system information (eg, in System Information Type 1 Block (SIB 1) or Remaining Minimum System Information (RMSI)). The specified set of PUCCH resources may contain 16 PUCCH resources.

On the other hand, in the case where the UE (after setting in the RRC layer) has the above-described PUCCH resource specific configuration information (UE uplink control channel specific configuration, PUCCH resource specific configuration), the UE may determine the specified PUCCH resource set according to the number of UCI information bits. .

The UE may determine one PUCCH resource (index) in the above-described PUCCH resource set (e.g., in a cell- or UE-specific PUCCH resource set) based on at least one of the value of a given field (e.g., a PUCCH resource indicator field) in the downlink. control information (DCI) (for example, in DCI format 1_0 or 1_1 used for PDSCH channel scheduling), the number (N _C ce) of Control Channel Elements (CCE) in the control resource set (CORESET) for PDCCH reception , in which the indicated DCI is transmitted, and the initial CCE (first CCE) index (n _{CCE 0} ) of the indicated PDCCH reception.

The PUCCH spatial relationship information (eg, RRC layer information "PUCCH-SpatialRelationInfo" element) may indicate a plurality of candidate beams for PUCCH transmission (spatial domain filter). The PUCCH spatial relationship information may indicate a spatial relationship between the reference signal and the PUCCH.

The PUCCH Spatial Relationship Information List may contain some elements (PUCCH Spatial Relationship Information Elements, IE). Each item of PUCCH spatial relationship information may contain, for example, at least one of a PUCCH spatial relationship information index (identifier, for example, pucch-SpatialRelationInfold), a serving cell index (identifier, for example, servingCellId), and reference signal information having spatial relationship with PUCCH.

Said reference signal information may be, for example, an SSB index, a CSI-RS index (eg, an NZP CSI-RS resource configuration identifier), or an SRS resource identifier and a BWP identifier. Said SSB index, CSI-RS index, and SRS resource identifier may be associated with at least one of a beam, resource, and port selected by measuring the corresponding reference signal.

A UE configured with more than one PUCCH spatial relationship information unit can control that one PUCCH spatial relationship information unit is active at any particular time for one PUCCH resource based on the PUCCH spatial relationship activation/deactivation MAC CE.

The specified PUCCH spatial relationship activation/deactivation MAC CE in NR version 15 is expressed as a total of three octets in octets (oct) 1-3 (8 bits × 3 = 24 bits).

This MAC CE may contain information about a target serving cell ID ("serving cell ID" field), a BWP identifier ("BWP ID" field), a PUCCH resource identifier ("PUCCH resource ID" field), or the like.

The specified MAC CE contains fields Si (i = 0-7). If the Si field indicates 1, then the UE activates the spatial relationship information that has been assigned the spatial relationship information identifier #i. If the Sj field indicates 0, then the UE deactivates the spatial relationship information assigned the spatial relationship information identifier #i.

The UE is configured to transmit an acknowledgment (acknowledgment, ACK) for the MAC CE activating the specified information about the PUCCH spatial relationship, and with the possibility of activating this information 3 ms after the specified transmission.

<Spatial relationship for SRS, PUSCH>

The UE is configured to receive information used to transmit a reference signal for measurement, such as a Sounding Reference Signal (SRS) (SRS configuration information, such as a parameter in an RRC layer control "SRS-Config").

More specifically, the UE may receive at least one of information about one or more SRS resource sets (SRS resource set information, e.g., RRC layer control "SRS-ResourceSet") and information about one or more SRS resources (SRS resource information , for example, the "SRS-Resource" element of the RRC layer control).

One set of SRS resources may be associated with a given number of SRS resources (may group a given number of SRS resources). Each SRS resource may be identified by an SRS Resource Indicator (SRI) or an SRS Resource Identifier.

Said SRS resource set information may include an SRS resource set identifier (SRS-ResourcesetId), a list of SRS resource identifiers (SRS-ResourceId) used in the resource set, an SRS resource type, and usage information of the SRS.

In this case, the SRS resource type can indicate any of the periodic SRS (English Periodic SRS, P-SRS), quasi-continuous SRS (English Semi-Persistent SRS, SP-SRS) and aperiodic SRS (English Aperiodic SRS, A-SRS , AP-SRS). Note that the UE is configured to periodically (or periodically after activation) transmit P-SRS and SP-SRS, and to transmit A-SRS based on an SRS request in DCI.

The specified usage (parameter "usage" of the RRC layer, parameter "SRS-SetUse" of the L1 (Layer-1)) can be, for example, beam management (beamManagement), codebook-based transmission (Eng. Codebook, CB), transmission is not based on the code book (eng. nonCodebook, NCB) and antenna change (antennaSwitching). The SRS for use in a codebook based or non-codebook based transmission may be used to determine a precoder for codebook or non-codebook based PUSCH transmission based on SRI.

For example, in the case of codebook-based transmission, the UE may determine a precoder for PUSCH transmission based on the SRI, the transmitted Rank Indicator (TRI) and the transmitted Precoding Matrix Indicator (TPMI). In the case of non-codebook based transmission, the UE may determine a precoder for PUSCH transmission based on the SRI.

The spatial relationship information for the SRS (eg, the RRC layer information "SpatialRelationInfo" element) may indicate information about the spatial relationship between a given reference signal and the SRS. This predetermined reference signal may be at least one of a Synchronization Signal/Physical Broadcast Channel (SS/PBCH) block, a Channel State Information Reference Signal (CSI-RS), and an SRS (e.g., another SRS ). The SS/PBCH block may be referred to as a Synchronization Signal Block (SSB).

The spatial relationship information for the SRS may include, as an index of the above-described predetermined reference signal, at least one of an SSB index, a CSI-RS resource identifier, and an SRS resource identifier.

It should be appreciated that in the present disclosure, the SSB index, SSB resource identifier, and SSB Resource Indicator (SSBRI) may be interpreted interchangeably. The CSI-RS index, the CSI-RS resource identifier, and the CSI-RS Resource Indicator (CRI) can be interpreted interchangeably. The SRS index, SRS resource identifier, and SRI may be interpreted interchangeably.

The spatial relationship information for the SRS may include a serving cell index, a BWP index (BWP ID), and the like corresponding to the predetermined reference signal described above.

In NR, upstream signal transmission can be controlled based on the presence or absence of beam correspondence (English Beam Correspondence, BC). Beam matching can be, for example, whether a node (e.g., a base station or a UE) is able to determine the beam used to transmit a signal (transmit beam, Tx beam) based on the beam used to receive a signal (receive beam, Rx beam). ) (figure 1).

Note that beam matching may be referred to as transmit/receive beam matching (Tx/Rx beam matching), beam relationship, beam calibration, calibrated/uncalibrated state, calibrated/uncalibrated relationship, degree of fit, degree of matching, or the like.

In the case where the UE is given the spatial relationship information for SSB or CSI-RS and SRS with respect to the SRS resource, for example, in the case of matching beams, the UE may use the same spatial domain filter to transmit the specified SRS resource (Spatial Domain Filter for Transmitting ) as a spatial domain filter (reception spatial domain filter) for receiving the specified SSB or CSI-RS. In this case, the UE may assume that the UE beam for SSB or CSI-RS reception is the same as the UE beam for SRS transmission.

In the case where the UE is set with respect to the SRS resource (target SRS) about the spatial relationship of the other SRS (reference SRS) and this SRS (target SRS), for example, in the case of no beam matching, the UE may use such the same spatial domain filter (transmission spatial domain filter) as the spatial domain filter (transmission spatial domain filter) for transmitting the reference SRS. In other words, in this case, the UE may assume that the UE beam for transmitting the reference SRS is the same as the UE beam for transmitting the target SRS.

The UE is configured to determine a spatial relationship for a PUSCH scheduled by a DCI based on the value of a given field in that DCI (eg, in a 0_1 format DCI), eg, an SRS Resource Indicator (SRI) field. More specifically, the UE may use the spatial relationship information for the SRS resource determined based on the value of a predetermined field (eg, the SRI field) (eg, the "SpatialRelationInfo" element of the RRC layer information) to transmit the PUSCH.

In the case of using codebook-based transmission for PUSCH, two SRS resources can be configured for the UE by RRC, and one of the two SRS resources can be indicated by DCI (a specific one-bit field). In the case of non-codebook-based transmission for PUSCH, four SRS resources can be configured for the UE by RRC, and one of the four SRS resources can be indicated by DCI (a specific two-bit field). To use a spatial relationship other than the specified two or four spatial relationships specified by the RRC layer, RRC reconfiguration is required.

Note that the DL-RS may be defined for the spatial relationship of the SRS resource used for the PUSCH. For example, for a given UE, for the SP-SRS, the RRC layer may define the spatial relationship of a plurality (eg, up to 16) of SRS resources, and one of the plurality of SRS resources may be indicated by the MAC CE.

(Standard Spatial Relationship)

If no spatial relationship information for a PUCCH specific configuration or for a specific SRS configuration is specified for a UE supporting beam matching, then, except for an SRS containing a beam management usage (usage = 'beamManagement') in a certain frequency band (e.g., in frequency range (FR) 2), the standard spatial relationship applied to the specified PUCCH special configuration or SRS special configuration can be any of the options 1-5 described below.

(Option 1)

The standard spatial relationship may be a standard TCI state or a standard PDSCH QCL guess, eg, a TCI state or a PDSCH QCL guess corresponding to the most recent (or latest) slot and lowest CORESET ID.

(Option 2)

The default spatial relationship may be one of the active TCI states for CORESET. (Option 3)

The default spatial relationship can be any of the following states: PDCCH scheduling TCI state for A-SRS or PUCCH and TCI default state or PDSCH default QCL guess for signals/channels other than A-SRS and PUCCH.

(Option 4)

The standard spatial relationship may be the QCL guess on CORESET #0. (Option 5)

The standard spatial relationship may be a path loss control reference.

If the non-beam matching UE is not given the spatial relationship information for the PUCCH special configuration or for the SRS special configuration, then, except for the SRS containing the use for beam steering in a certain frequency band (e.g., FR2), to the specified special configuration PUCCH or special SRS configuration can apply this standard spatial relationship.

(Spatial relationship of PUSCH scheduled by DCI format 0_0)

DCI format 0_1 contains SRI, DCI format 0_0 does not contain SRI.

In NR Release 15, for a PUSCH in a cell scheduled by DCI format 0_0, the UE transmits the PUSCH according to the spatial relationship corresponding to the special PUCCH resource having the lowest ID in the active uplink BWP of the indicated cell, if available. The specified PUCCH specific resource may be a UE-specific PUCCH resource (specified by an upper layer PUCCH-Config parameter).

Accordingly, for a cell that has not been given a PUCCH resource (eg, a secondary cell (SCell)), PUSCH cannot be scheduled by DCI format 0_0.

In case PUCCH in SCell (PUCCH carried in SCell) is not configured, UCI is sent in PCell. When the PUCCH is configured in the SCell, the UCI is sent to the PUCCH-SCell. Accordingly, it is not necessary to set the PUCCH resource and the spatial relationship information in all SCells, and thus it is possible to have a cell in which the PUCCH resource is not set.

DCI format 0_1 contains a Carrier Indicator Field (CIF), DCI format 0_0 does not contain CIF. Accordingly, even if the PUCCH resource for PCell is set, PUSCH scheduling in SCell on multiple carriers (English Cross-Carrier Scheduling) via DCI format 0_0 in PCell is not possible.

(Transmission power control)

<PUSCH transmission power control>

In NR, PUSCH transmission power control is performed based on a Transmission Power Control (TPC) command, also called a value, up-down value, correction value, or the like, which is indicated by a value of a predetermined field in the DCI (also called TPC command field or the like).

в акте i передачи PUSCH (также называемом временным интервалом передачи или т.п.) может выражаться нижеприведенной формулой (1). Состоянием корректировки управления мощностью может называться значение, основанное на команде ТРС, имеющей индекс I состояния корректировки управления мощностью, накопленном значении указанной команды ТРС и значении для случая с обратной связью. I может называться индексом для случая с обратной связью.For example, in the case where the UE uses the parameter set having index j (parameter set for the open-loop case) and index I of the power control adjustment state (PUSCH power control adjustment state) to transmit the PUSCH on the active uplink BWP b carrier f of the serving cell c , transmit power PUSCH

in the act i of transmission PUSCH (also called a transmission time interval or the like) may be expressed by the following formula (1). The power control adjustment state may be referred to as a value based on a TPC command having a power control adjustment state index I, an accumulated value of said TPC command, and a value for the closed loop case. I can be called an index for the feedback case.

The PUSCH transmission act i is a time slot in which the PUSCH is transmitted and may include, for example, one or more symbols, one or more slots, and the like.

(Formula 1)

представляет, например, параметр для целевой принятой мощности, заданный для активной восходящей BWP b несущей f обслуживающей соты с в акте i передачи (также называемый, например, параметром для смещения мощности передачи, смещением Р0 мощности передачи, целевым параметром принятой мощности или т.п.).Here

(Lots of TRPs)

In NR, the use of one or more Transmission/Reception Points (TRPs) (a set of TRPs) of one or more panels (a set of panels) is being studied in order to perform downstream transmission in a UE. Performing uplink transmission from a UE to one or multiple TRPs is also being studied.

It should be noted that the specified set of TRPs may correspond to one cell ID (eng. Cell ID) or different Cell IDs. The specified cell ID may be a physical cell ID or a virtual cell ID.

From each TRP of a plurality of TRPs, different code words (eng. Code Word, CW) and different levels can be transmitted. Non-Coherent Joint Transmission (NCJT) is being studied as one of the transmission modes using multiple TRPs.

In NCJT, for example, TRP 1 performs modulation mapping and layering mapping on the first codeword, and uses the first precoding of the first number of layers (eg, two layers) to transmit the first PDSCH. In addition, TRP 2 performs baseband mapping and layering mapping on the second codeword for transmitting the second PDSCH, and uses the second precoding of the second number of layers (eg, two layers). These first and second PDSCHs may be considered to have no quasi-proximity to each other.

It should be appreciated that the plurality of PDSCHs transmitted by the NCJT may be defined with partial or complete overlap in at least one of the time domain and the frequency domain. In other words, the first PDSCH of the first TRP and the second PDSCH of the second TRP may overlap in at least one of the time or frequency resources.

(Power control configuration)

In NR version 15, to comply with the requirement to change the spatial relationship, a transition between multiple states of power control can be performed without feedback (Eng. Open-Loop TPC, OL-TPC) or with feedback (Eng. Closed-Loop TPC, CL-TPC) by using the SRI field in DCI. In the case where the use of the SRS resource set is a codebook based transmission, the maximum value of the SRI field is 2 (or the length of the SRI field is 1 bit), and in the case where the use of the SRS resource set is a non-codebook based transmission, the maximum value the SRI field is 4 (or the length of the SRI field is 2 bits).

To configure the power control configuration for PUSCH, the PUSCH power control information (PUSCH-PowerControl) in the PUSCH configuration information (PUSCH-Config) includes a power control configuration list (SRI-PUSCH-PowerControl) associated with the SRI field value (sri-PUSCH-MappingToAddModList ). Said power control configuration comprises a power control configuration identifier (SRI-PUSCH-PowerControlld) corresponding to the value of the SRI field, a path loss control reference signal identifier (sri-PUSCH-PathlossReferenceRS-ld) indicating a path loss control reference signal, a set identifier P0 -α (sri-p0-PUSCH-AlphaSetld) indicating a set of P0 and α, and an identifier for the closed loop case (sri-PUSCH-Closed Loop Index) corresponding to the power control state I.

At least one of the path loss control reference signal identifier, the P0-α set identifier, and the identifier for the feedback case may be referred to as a power control (transmit power control, TPC) parameter. At least one of a path loss control reference signal identifier and a plurality identifier P0-α is used for open-loop power control and may therefore be referred to as an open-loop power control parameter (OL-TPC). The identifier for the closed-loop case is used for closed-loop power control, and therefore may be referred to as a closed-loop power control parameter (CL-TPC).

For example, as shown in FIG. 2, an SRI field value of 0 may be associated with a power control configuration #0 containing P0 #0 and #0, path loss control reference signal #0, and power control adjustment state #0 (I=0), and an SRI field value of 1 may be associated with a power control configuration #1 containing P0 #1, and #1, a path loss control reference signal #1, and a power control adjustment state #1 (I =1). The corresponding power control configuration is indicated to the UE via the SRI field.

In the case where only one SRS resource is specified for the UE, the length of the SRI field is 0 bits.

(deltaF- PUCCH -f0, deltaF-PUCCH-f1, deltaF-PUCCH-f2, deltaF-PUCCH-f3, deltaF-PUCCH-f4) для каждого формата PUCCH, множество Р0 (p0-Set), множество опорных сигналов контроля потерь в тракте (сигналы pathlossReferenceRS) и информацию, указывающую, следует ли использовать два состояния корректировки управления мощностью PUCCH (twoPUCCH-PC-AdjustmentStates). Опорный сигнал контроля потерь в тракте может выражаться индексом SSB (SSB-lndex) или CSI-RS (идентификатором ресурса NZP-CSI-RS (NZP-CSI-RS-Resourceld)).To configure the power control configuration for the PUCCH, the power control configuration (PUCCH-PowerControl) is included in the PUCCH configuration information (PUCCH-Config). This power control configuration contains the correction value

(deltaF-PUCCH-f0, deltaF-PUCCH-f1, deltaF-PUCCH-f2, deltaF-PUCCH-f3, deltaF-PUCCH-f4) for each PUCCH format, P0 set (p0-Set), loss control reference set in path (pathlossReferenceRS signals) and information indicating whether two PUCCH power control adjustment states (twoPUCCH-PC-AdjustmentStates) should be used. The path loss control reference may be expressed by an SSB index (SSB-Index) or a CSI-RS (NZP-CSI-RS Resource Identifier (NZP-CSI-RS-ResourceId)).

So in NR version 15 it is possible to change power management configurations.

On the other hand, changing the spatial relationship for A-SRS (uplink transmission) by MAC CE is being studied. For example, as shown in FIG. 3, the uplink transmission beam is changed by the MAC CE from uplink transmission beam #0 for TRP 1 to uplink transmission beam #1 for TRP2.

If the parameters for transmit power control (transmission power control parameter, power control parameter) are not appropriately adjusted in the event of a change in the spatial relationship of a particular uplink transmission, the system efficiency may decrease.

Based on this, the authors of the present invention proposed a method for determining the power control parameters of a particular uplink transmission.

<Implementation 1>

"Standard Spatial Relationship"

The standard spatial relationship may be used in at least one of Cases 1 and 2 described below.

[Case 1] In the case where the spatial relationship information of a specific uplink transmission is not set, the UE for that uplink transmission may use the standard spatial relationship.

For example, when no spatial relationship information for a PUCCH special configuration or for a special SRS configuration is specified for a UE supporting beam matching, then, except for the SRS containing the use for beam management (usage = 'beamManagement') in a certain frequency range (for example , in the frequency band FR 2), the UE may apply a standard spatial relationship to the PUCCH ad hoc configuration or SRS ad hoc configuration or PUSCH ad hoc configuration.

For example, when no spatial relationship information for a PUCCH special configuration or for a special SRS configuration is specified for a UE not supporting beam matching, then, except for the SRS containing the use for beam steering in a certain frequency band (e.g., FR2), the standard spatial the relationship may apply to a specific PUCCH configuration or to a specific SRS configuration.

[Case 2] When a PUSCH in a cell for which no PUCCH resource is specified is scheduled by DCI format 0_0, a standard spatial relationship may be used if available.

For example, in a cell for which no PUCCH resource is specified in the active uplink BWP, the standard spatial relationship, if present, may be applied to the spatial relationship of the PUSCH channel scheduled by DCI format 0_0.

For the standard spatial relationship, the standard TCI state or the standard QCL guess of a particular downstream reception may be used.

TCI standard state or QCL standard guess of a specific downstream reception, TCI state of the CORESET having the lowest CORESET ID in the most recent slot, reference signal referring to the QCL parameter used to indicate the QCL of the PDCCH of that CORESET associated with the search space being monitored where one or more CORESETs in the active BWP of the serving cell have the lowest CORESET-ID in the latest slot monitored by the UE, the TCI state or QCL guess of the CORESET that has the lowest CORESET-ID in the latest slot and is associated with the search space monitored, the TCI state or QCL guess of the CORESET that has the lowest CORESET-ID in a particular slot and is associated with the monitored search space, the TCI state or QCL guess of a specific CORESET, the TCI state or QCL guess of the downstream receive corresponding to a particular uplink transmission (e.g., the downlink initiating that particular uplink, the downlink scheduling that particular uplink, or the downlink scheduling the downlink corresponding to that particular uplink), and a reference signal related to the QCL parameter of the particular downlink. (a reference signal having a QCL relationship with a particular downstream reception) may be interpreted interchangeably.

The specified latest slot may be the latest slot for a particular downstream reception.

The specified latest slot may be the latest slot for the start symbol (or before the specified symbol) of a particular uplink.

The specified latest slot may be the latest slot for the start or last symbol (or before the specified symbol) of the downstream receive corresponding to a particular upstream transmission. For example, in the case where the specific uplink transmission is a PUCCH, the downlink reception corresponding to that specific uplink transmission may be the PDSCH corresponding to the specified PUCCH (PDSCH corresponding to the HARQ-ACK transmitted on the PUCCH).

The standard spatial relationship can be any of the standard spatial relationships 1-5 described below.

[Standard Spatial Relationship 1] The standard spatial relationship may be a standard TCI state or a standard QCL guess of the PDSCH. The specified downstream receive may be PDSCH.

[Standard Spatial Relationship 2] The standard spatial relationship may be one of the active TCI states (or activated TCI states) of the control resource set (CORESET).

For CORESET, multiple TCI states can be active. In this case, the active TCI state selected as the standard spatial relationship may be a standard reference signal, or a standard TCI state, or a standard QCL guess. Said specific downstream reception may be a Control Resource Set (CORESET) PDCCH.

[Standard Spatial Relationship 3] In the case where the particular uplink transmission corresponds to the PDCCH, the standard spatial relationship of the specific uplink transmission may be the TCI state of the indicated PDCCH. For example, in the case where the specific uplink is an A-SRS, the PDCCH corresponding to that specific uplink may be the PDCCH initiating said A-SRS. For example, in the case where the specific uplink transmission is a PUCCH in which a HARQ-ACK is transmitted, the PDCCH corresponding to that specific uplink transmission may be a PDCCH scheduling a PDSCH and indicating a time slot for the HARQ-ACK of the specified PDSCH. The specified downstream receive may be a PDCCH. In the case where a particular upstream transmission does not match the PDCCH, the standard TCI state or the standard QCL guess of the PDSCH can be used. A case where a particular uplink does not correspond to a PDCCH may be a case where that particular uplink is not an A-SRS or a PDCCH. The specified downstream receive may be PDSCH.

[Standard spatial relationship 4] The standard spatial relationship may be the QCL guess of the set (CORESET) #0 of control resources (CORESET having identifier 0).

[Standard Spatial Relationship 5] The standard spatial relationship may be a path loss control reference signal. The specified path loss control reference may be any of PathlossReferenceRS in SRS-ResourceSet in SRS-Config, PUCCH-PathlossReferenceRS in PUCCH-PowerControl in PUCCH-Config, and PUSCH-PathlossReferenceRS in PUSCH-PowerControl in PUSCH-Config. The standard spatial relationship of a specific uplink may be a path loss control reference signal related to said specific uplink. The specified path loss control reference may be CSI-RS or SSB. The path loss control reference signal may correspond to the TCI active state.

In the case where a path loss control reference (DL-RS for path loss measurement) is specified for a UE by upper layer signaling, said UE may use this specified path loss control reference as a standard spatial relationship. In the case where the UE is not configured to use the path loss control reference signal via upper layer signaling, said UE may determine the ID of the path loss control reference signal for PUSCH transmission (reference signal resource index q _d ) to use this loss control reference signal in tract as a standard spatial relationship.

"Power control parameter"

The probable values for the TCI state, used as a standard spatial relationship, may be related to the probable values for the power control parameter. Said power control parameter may be at least one of a path loss control reference signal, P0, α, and a power control adjustment state.

The relationship between one or more probable values for the TCI state and one or more probable values for a power control parameter may be defined in the technical documentation (eg, a table), or may be specified by higher layer signaling (eg, a list).

In the case that a standard spatial relationship is used for a particular uplink transmission, the UE may use for the specific uplink power control parameters probable values for the power control parameter associated with the TCI state used for the standard spatial relationship.

The case in which a standard spatial relationship is used for a particular uplink transmission may be at least one of cases 1 and 2.

In the case where the power control parameters are not specified by upper layer signaling and the standard spatial relationship is used for a specific uplink transmission, the UE may use for the uplink specific power control parameters probable values for the power control parameter associated with the TCI state used for the standard spatial relationship. .

In the case where a standard spatial relationship is used for a specific uplink transmission, the UE may use for the power control parameters of the specific uplink transmission probable values for the power control parameter associated with the TCI state used for the standard spatial relationship, whether or not the power control parameters are set. through higher level signaling.

In the case where the TCI state or QCL guess used as the standard spatial relationship changes, the UE may change the specific uplink transmission power control parameters to probable values for the power control parameter associated with the specified TCI state (auto power control parameter change). The TCI state or QCL guess may be changed by transmitting at least one of the MAC CE, DCI, and PRACH.

For example, in the case where the standard spatial relationship is the TCI state of the PDCCH, and this TCI state of the PDCCH is changed by the MAC CE, the UE may change the specific uplink transmission power control parameters to probable values for the power control parameter associated with the specified TCI state given via MAC CE.

This PRACH transmission may be a transmission in a random access operation or a transmission in Beam Failure Recovery (BFR). Said standard spatial relationship may be a QCL guess of at least one of the PUSCH and PUCCH. The specified QCL guess may be the SSB corresponding to the PRACH transmission act (PRACH resource).

For example, in the case where the standard spatial relationship is the PDCCH QCL guess and this QCL guess is changed by PRACH transmission, the UE may change the specific uplink transmission power control parameters to probable values for the power control parameter associated with the changed QCL guess (DL-RS) .

There may be a case in which the TCI state is not explicitly reported to the UE. For example, the act of transmitting a PRACH may be associated with SSB. In the case where the UE transmits the PRACH, the SSB corresponding to the specified PRACH transmission act may be determined as the QCL guess for CORESET #0.

The UE may indicate the need to support automatic change of specific uplink power control parameters as part of the UE capability information. Automatic change of the power control parameter may be set for the UE only when the UE reports the need to support automatic change of the power control parameter.

In the case where, under a certain condition and using a standard spatial relationship for a particular uplink transmission, the TCI state used for that standard spatial relationship has changed, the power control parameters of the specific uplink transmission can be changed to probable values for the power control parameter associated with the specified state. TCI. Said condition may be an automatic change of the power control parameters set by the upper layer signaling. The condition may be a message from the UE to support automatic change of power control parameters.

<Implementation 2>

In the case where a standard spatial relationship is used for a particular uplink transmission, the UE may use the TCI state signal DL-RS or the QCL guess used for the standard spatial relationship for the path loss control reference signal. The specified DL-RS may be any of TRS, CSI-RS and SSB.

In the case where the TCI state used for the standard spatial relationship is changed or enabled by the MAC CE, the path loss control reference signal for a specific uplink transmission may be changed to the DL-RS given by the specified MAC CE.

For example, as shown in FIG. 4, in the case where the TCI state of the specific downlink is used for the standard spatial relationship of the specific uplink, the UE may use SSB #0 in the specified TCI state for the path loss control reference signal for the specific uplink. In the case where the TCI state is changed from SSB #0 to SSB #1 by the MAC CE, the UE may use SSB #1 in the changed TCI state for the path loss control reference for a particular uplink transmission.

The TCI state used for the standard spatial relationship may be the TCI state of the PDCCH of the CORESET associated with the search space being monitored, where one or more CORESETs in the active BWP of the serving cell has the lowest CORESET-ID in the latest slot being monitored. led by UE. In the case where the TCI state of the PDCCH is changed by the MAC CE, the path loss control reference signal for a particular uplink transmission may change to the DL-RS given by the specified MAC CE.

In the case where the QCL guess used for the standard spatial relationship is changed, the UE may change the path loss control reference signal for a particular uplink to the modified DL-RS of the specified QCL guess.

Said standard spatial relationship may be a QCL guess for a particular PDCCH. The QCL guess change may be performed by PRACH transmission or PRACH transmission in beam failure recovery (BFR). Said particular uplink transmission may be at least one of PUSCH and PUCCH. The DL-RS of said QCL suggestion may be an SSB corresponding to a PRACH transmission act (PRACH resource).

In other words, in the case where the QCL guess of the PDCCH used for the standard spatial relationship of a specific uplink transmission is changed by PRACH transmission, the path loss control reference signal for the specific uplink transmission may be changed to the SSB corresponding to the specified PRACH transmission event.

There may be a case in which the TCI state is not explicitly reported to the UE. For example, the act of transmitting a PRACH may be associated with SSB. In the case where the UE transmits the PRACH, the SSB corresponding to the specified PRACH transmission act may be determined as the QCL guess for CORESET 0.

The pathloss control reference signal for a particular uplink is made dependent on the spatial relationship of the particular uplink, which enables proper beam steering.

According to this implementation, the path loss control reference signal may change in response to a change in the TCI state or QCL assumptions used for the standard spatial relationship, which makes it possible to determine the appropriate transmit power.

<Implementation 3>

In case the TCI state or QCL assumption used for the standard spatial relationship is changed or activated, the power control parameter set containing at least one of P0 and α for a particular uplink transmission may change. This set can be interpreted as a P0-α set (eg, p0-AlphaSets, p0-PUSCH-AlphaSet), a P0 set (eg, p0-Set), or the like.

The P0-α set for a particular uplink may be related to probable values for the TCI state or QCL or DL-RS guess. The UE may use the P0-α set corresponding to the changed TCI state or QCL or DL-RS guess to control the transmit power of a particular uplink.

For example, likely values for the set P0-α may be associated with likely values for a TCI state identifier (TCI-StateId). One or more TCI state identifiers may be defined, for example, by a PDCCH TCI state list (tci-StatesPDCCH-To Release List) in the CORESET configuration information (ControlResourceSet). For example, as shown in FIG. 5, the set of possible values for the set P0-α may be associated with the set of possible values for the TCI state identifier.

The relationship between the one or more candidate values for the TCI state and the one or more candidate values for the power control parameter may be defined in the technical documentation or may be specified by upper layer signaling.

Similar to Implementation 2, in the case where a standard spatial relationship is applied to a particular uplink transmission, the UE for the path loss control reference signal may use the DL-RS of the TCI state or the guess of the QCL used for said standard spatial relationship.

The likely values for the power control parameter set, comprising the P0-α set set and the path loss control reference, may be related to the TCI state or the QCL or DL-RS guess. For example, candidate values for a plurality of power control parameters may be associated with candidate values for a TCI state identifier (TCI-StateId).

According to this implementation, the P0-α set may change in response to the TCI state or QCL guess used for the standard spatial relationship, which allows a suitable transmit power to be determined.

<Implementation 4>

In the case where the TCI state or QCL assumption used for the standard spatial relationship of a specific uplink is changed or activated, the power control adjustment state for the specific uplink may change. The specified power control adjustment state may be at least one of the PUSCH power control adjustment state f _b,f,c (i, I), the PUCCH power control adjustment state g _{b, f, c} (i, I), and the state h _{b, f, c} (i, I) SRS power control adjustments. The standard state (standard accumulated value of the TPC command) may be zero.

The number of power control adjustment states that the UE can calculate or store may depend on the technical capability of the UE. The UE may report the number of power control adjustment states that the UE may calculate or store as UE capability information. The number of power control adjustment states given to the UE may be less than or equal to this reported number.

The UE is configured to determine the state of the power control adjustment in accordance with at least one of the state change methods 1-4 described below.

"Mode 1 State Change"

When the TCI state or QCL assumption of the standard spatial relationship used for a particular uplink transmission changes, the UE may reset the power control adjustment state for that particular uplink transmission to the standard state.

"Mode 2 state change"

In the case where the TCI state or the QCL guess used for the standard spatial relationship is changed or activated, the power control adjustment state of a particular uplink transmission may change.

The power control adjustment state or power control adjustment state identifier or index for the feedback case (eg, I) for a particular uplink may be associated with probable values for the TCI state or QCL or DL-RS guess. For example, as shown in FIG. 6, a set of candidate values for an index for the feedback case may be associated with a set of candidate values for a TCI state identifier.

The relationship between the one or more probable values for the TCI state and the one or more probable values for the power control adjustment state may be defined in the technical documentation or may be specified by upper layer signaling.

The UE may calculate or store a plurality of power control adjustment states corresponding to a plurality of identifiers (TCI states or QCL or DL-RS guesses). The power control adjustment state corresponding to the changed ID may be referred to as the power control active state.

The UE may use, for a particular uplink transmission, the active power control adjustment state corresponding to the changed TCI state for closed loop transmit power control (CL-TPC).

The UE may not be required to calculate or store an inactive power control adjustment (TPC command accumulation) state. In other words, the UE may only calculate or store the active power control adjustment state.

The UE may calculate or store an active power control adjustment state and an inactive power control adjustment state.

Similar to Implementation 2, in the case where a standard spatial relationship is applied to a particular uplink transmission, the UE for the path loss control reference signal may use the DL-RS of the TCI state or the guess of the QCL used for said standard spatial relationship.

Similar to implementation 3, in the case where a standard spatial relationship is used for a specific uplink transmission, the UE may use the P0-α set corresponding to the TCI changed state or QCL or DL-RS assumption to control the transmission power of the specific uplink transmission.

According to this implementation, the power control adjustment state may vary depending on the TCI state or the QCL guess used for the standard spatial relationship, which makes it possible to determine the appropriate transmit power.

<Implementation 5>

In case the TCI state or QCL assumption used for the standard spatial relationship is changed or activated, the power control configuration for a particular uplink transmission may change.

The power control configuration (eg, SRI-PUSCH-PowerControl) may comprise at least one power control parameter of a path loss control reference signal identifier, a P0-α set identifier, and an identifier for the feedback case (power control adjustment state) as shown in the above-described figure 2. The specified power control configuration may be defined by a power control configuration identifier (SRI).

One or more candidate values for a power control configuration or a power control configuration identifier or SRI field value for a particular uplink transmission may be associated with one or more candidate values for the TCI state or QCL or DL-RS guesses. For example, as shown in FIG. 7, a set of candidate values for an SRI field may be associated with a set of candidate values for a TCI state identifier. Each power control configuration may contain one TCI state identifier. The value of the SRI field may be considered as a TCI state identifier.

The relationship between one or more probable values for the TCI state and one or more probable values for the power control configuration may be defined in the technical documentation or may be specified by upper layer signaling.

The UE may use a power control configuration corresponding to the changed TCI state or QCL or DL-RS guess to control the transmit power of a particular uplink transmission.

According to this implementation, the power control configuration may change depending on the state of the TCI or the QCL assumption used for the standard spatial relationship, which makes it possible to determine the appropriate transmit power.

(Radio communication system)

The following describes the configuration of a radio communication system in accordance with one implementation of the present invention. In this radio communication system, the radio communication method according to each of the above-described implementations of the present invention may be used for communication individually or in combination.

Fig. 8 represents an example of a generalized configuration of a radio communication system in accordance with one implementation.

The radio communication system 1 is configured to support dual connectivity between multiple Radio Access Technologies (RAT) (Multi-RAT Dual Connectivity, MR-DC). MR-DC may contain a dual connection (double connection E-UTRA-NR, EN-DC) between LTE (Evolved Universal Terrestrial Radio Access, E-UTRA)) and NR, dual connection (dual connection NR-E-UTRA, NE-DC) between NR and LTE, etc.

In EN-DC, the LTE Base Station (eNB) (E-UTRA) is the Master Node (MN) and the NR Base Station (gNB) is the Secondary Node (SN). In the NE-DC, the NR base station (gNB) is the primary node (MN) and the LTE base station (eNB) (E-UTRA) is the secondary node (SN).

Please note that frequency ranges, definitions, etc. FR1 and FR2 are not limited in any way, and, for example, FR1 may correspond to a frequency range above FR2.

The user terminal 20 is configured to communicate using at least one of a Time Division Duplex (TDD) and a Frequency Division Duplex (FDD) on each EN.

The plurality of base stations 10 may be connected by a wired connection (for example, a fiber optic cable in accordance with the Common Public Interface (CPRI) standard, an X2 interface, etc.) or a wireless connection (for example, NR communication) . For example, if an NR link is used as the reverse connection between base stations 11 and 12, then the base station 11 corresponding to the older station may be called the Integrated Access and Backhaul (IAB) donor, and the base station 12, the corresponding relay station may be called an IAB node.

Base station 10 may be connected to core network 30 through another base station 10 or directly. The core network 30 may comprise at least one of an Evolved Packet Core (EPC), a 5G Core Network (5GCN), a Next Generation Core, NGC), etc.

The user terminal 20 may be a terminal supporting at least one of the communication schemes such as LTE, LTE-A, 5G, and the like.

The radio communication system 1 may use a wireless access scheme based on orthogonal frequency division multiplexing (OFDM). For example, at least one of the downlink (DL) and uplink (UL) can use OFDM with a cyclic prefix (Eng. Cyclic Prefix OFDM, CP-OFDM), OFDM with spread spectrum on Discrete Fourier Transform Spread OFDM (DFT-s-OFDM), Orthogonal Frequency Division Multiple Access (OFDMA), Frequency Division Multiple Access (OFDM) .Single Carrier Frequency Division Multiple Access, SC-FDMA), etc.

The wireless access scheme may be referred to as a "signal type". Note that in the radio communication system 1, a different wireless access scheme (eg, different single carrier transmission scheme, different multi-carrier transmission scheme) may be used as the wireless access scheme in the uplink and downlink.

In the radio communication system 1, a downlink shared channel (Physical Downlink Shared Channel, PDSCH) shared by all user terminals 20, a broadcast channel (Physical Broadcast Channel, PBCH) can be used as downlinks. ), downlink control channel (Physical Downlink Control Channel, PDCCH), etc.

(Modifications)

It should be appreciated that the terms described in the disclosure of the present invention and the terms necessary for understanding the present invention may be replaced by other terms conveying the same or similar meaning. For example, "channel", "symbol", and "signal" (or signaling) can be interpreted interchangeably. In addition, "signals" can be "messages". The reference signal can be abbreviated as RS (Reference Signal) and called pilot, pilot signal, etc. depending on the applicable standard. A Elementary Carrier (EC) may be referred to as a cell, a frequency carrier, a frequency carrier, and so on.

A radio frame may be formed from one or more periods (frames) in the time domain. Each of one or more periods (frames) constituting a radio frame may be referred to as a subframe. Further, a subframe in the time domain may be formed from one or more slots. A subframe may be a time slot of a fixed duration (eg, 1 ms) independent of numerology.

In this context, numerology may refer to a communication parameter applied to at least one of the transmission and reception of a given signal or channel. For example, the numerology may indicate at least one of Subcarrier Spacing (SCS), bandwidth, symbol length, cyclic prefix length, transmission time interval (TTI), number of symbols per TTI, radio frame structure, specific filtering processing. performed by the transceiver in the frequency domain, specific windowing performed by the transceiver in the time domain, and so on.

A slot in the time domain may be formed by one or more symbols (OFDM symbols, SC-FDMA symbols, etc.). The slot can be a temporary element depending on numerology.

A slot may contain a plurality of mini-slots. Each mini-slot in the time domain may be formed from one or more symbols. A mini-slot may be referred to as a sub-slot. A mini-slot may be formed from symbols whose number is less than the number of symbols in the slot. PDSCH (or PUSCH) transmission in a tile larger than a mini-slot may be referred to as PDSCH Mapping Type A (PUSCH). PDSCH (or PUSCH) transmission using a mini-slot may be referred to as PDSCH Map Type B (PUSCH).

The radio frame, subframe, slot, mini-slot, and symbol are temporary elements in signaling. The radio frame, subframe, slot, mini-slot, and symbol may be referred to by other suitable names. It should be appreciated that temporal elements such as frame, subframe, slot, mini-slot, and symbol may be interpreted interchangeably in the present disclosure.

For example, one subframe, multiple consecutive subframes, one slot, or one mini-slot may be referred to as a transmission time interval (TTI). Thus, at least one of the subframe and the TTI may be a subframe (1 ms) in existing LTE, a period shorter than 1 ms (for example, 1 to 13 symbols), or a period longer than 1 ms. Note that an element representing a TTI , may not be called a subframe, but a slot, mini-slot, or the like.

In this document, TTI is understood to mean, for example, the smallest scheduling time element in a radio communication. For example, in LTE systems, the base station schedules the allocation of radio resources (eg, frequency band and transmission power allowed for use by each user terminal) to the user terminal in units of TTI. The definition of TTI intervals is not limited to this.

The TTIs may be time units for transmitting channel-encoded data packets (transport blocks), code blocks, or codewords, or the TTI may be a processing time unit in scheduling, link adaptation, and so on. It should be appreciated that even with given TTIs, the time interval (eg, number of symbols) for which transport blocks, code blocks and/or codewords are actually mapped may be shorter than these TTIs.

Note that when a TTI is referred to as one slot or one mini-slot, the minimum time element in scheduling may be one or more such TTIs (ie, one or more slots or one or more mini-slots). Moreover, the number of slots (number of mini-slots) constituting this minimum scheduling time element can be controllable.

A TTI with a time duration of 1 ms may be called a regular TTI (TTI in 3GPP Releases 8-12), long TTI, regular subframe, long subframe, slot, and so on. A TTI that is shorter than a regular TTI may be referred to as a shortened TTI, a short TTI, a partial or fractional TTI, a shortened subframe, a short subframe, a mini-slot, a subslot, a slot, and the like.

Note that a long TTI (e.g., regular TTI, subframe, etc.) may be interpreted as a TTI with a time duration greater than 1 ms, and a short TTI (e.g., shortened TTI) may be interpreted as a TTI with a duration shorter than the duration of the long TTI and not less than 1 ms.

Resource block (English Resource Block, RB), which is a resource allocation element in the time domain and in the frequency domain, may contain one subcarrier or multiple subcarriers, consecutive without gaps in the frequency domain. The number of subcarriers in a resource block may be the same regardless of the numerology, and may be 12, for example. The number of subcarriers in resource blocks may be determined based on the numerology.

In the time domain, a resource block may contain one symbol or multiple symbols, and may be one slot, one mini-slot, one subframe, or one TTI in length. One TTI, one subframe, etc. may be formed by a single resource block or multiple resource blocks.

It should be noted that one or more resource blocks (RB) can be called a physical resource block (eng. Physical RB, PRB), sub-carrier group (eng. Sub-Carrier Group, SCG), group of resource elements (eng. Resource Element Group, REG ), a pair of PRBs, a pair of RBs, and the like.

Further, a resource block can be formed by a single resource element (English Resource Elements, RE) or multiple REs. For example, one RE may correspond to a radio resource region consisting of one subcarrier and one symbol.

The Bandwidth Part (BWP; may also be called a partial band, etc.) may be a subset of consecutive uninterrupted common resource blocks (common RBs) for a particular numerology on a particular carrier. In this case, the common RB may be indicated by the RB index with respect to the common reference point of that carrier. The PRB may be defined in a particular BWP and may be numbered in that BWP.

A BWP may contain an uplink BWP (uplink BWP) and a downlink BWP (downlink BWP). One or multiple BWPs may be configured for a UE on a single carrier.

At least one of the configured BWPs may be active and the UE may assume that the given signal/channel is not transmitted/received outside of the active BWPs. It should be noted that the terms "cell", "carrier", etc. in this disclosure may be interpreted as "BWP".

Note that the above-described configurations of radio frames, subframes, slots, mini-slots, symbols, etc. are only examples. For example, various changes are possible with respect to the number of subframes contained in a radio frame, the number of slots per subframe or radio frame, the number of mini-slots contained in a slot, the number of symbols and RBs contained in a slot or mini-slot, the number of subcarriers contained in a RB, number of symbols in TTI, symbol duration, cyclic prefix (CPU) length, etc.

The information and parameters described in this disclosure may be represented by absolute values or relative values with respect to setpoints, or may be represented by other relevant information. For example, the radio resources may be indicated by predetermined indexes.

Names used for parameters, etc. in the present disclosure are not limiting in any respect. Mathematical expressions using these parameters and the like may differ from those expressly disclosed in the present disclosure. For example, since the various channels (PUCCH, PDCCH, etc.) and information elements may be referred to by any suitable names, the various names given to these individual channels and information elements are not limiting in any respect.

For example, the communication of information in the present invention can be performed by using physical layer signaling (e.g., downlink control information (DCI), uplink control information (UCI)), upper layer signaling (e.g., radio resource control (RRC) layer signaling), broadcast information (Basic Information Block (MIB), System Information Blocks (SIB), etc.), Media Access Layer (MAC) signaling, other signals, and/or combinations thereof.

Physical layer signaling may be referred to as LI/1 control information/L1/L2 control signals) (English Layer 2(L1/L2, layer 1/layer 2), L1 control information (L1 control signal), etc. RRC layer signaling may be called an RRC message, and this signaling may be, for example, an RRC connection establishment message, an RRC connection reconfiguration message, etc. MAC layer signaling may be transmitted using, for example, MAC control elements (MAC control element, MAC CE ).

The message of the given information (eg, the message that X does not change) need not be communicated explicitly, but may be communicated implicitly (by, for example, not reporting this given information or by reporting other information).

Tests can be performed on values represented by a single bit (0 or 1), on boolean values representing true or false, or by comparing numeric values (eg, by comparing with a given value).

Software, whether called a program, internal program, middleware, microcode, hardware description language or otherwise, should be understood in a broad sense to include instructions, instruction sets, code, code segments, program codes, programs, subroutines, program modules, applications, application programs, software packages, objects, executable files, threads of execution, procedures, functions, etc.

Programs, commands, information, etc. can be transmitted and received over the communication medium. For example, if a program is transmitted from a website, server, or other remote source using at least one of the wired technologies (coaxial cables, fiber optic cables, twisted-pair cables, Digital Subscriber Lines, DSL) etc.) and wireless technical means (infrared radiation, microwaves, etc.), then at least one of these wired and/or wireless technical means is also included in the concept of a communication medium.

The terms "system" and "network" as used in this disclosure may be used interchangeably. "Network" may mean a device (eg, a base station) that is part of a network.

In the present disclosure, terms such as "precoding", "precoding device", "weight (weight in precoding)", "quasi-proximity" (English Quasi-Co-Location, QCL), "indicator status transmission configuration" (TCI status), "spatial relationship", "spatial domain filter", "transmit power", "phase rotation", "antenna port", "antenna port group", "level", "number of levels", " rank, resource, resource set, resource group, beam, beam width, beam angle, antenna, antenna element, panel, etc. can be used interchangeably.

In this disclosure, terms such as "base station (BS)", "radio base station", "fixed station", "NodeB", "eNodeB (eNB)", "gNodeB (gNB)", "access point" , Transmission Point (TP), Reception Point (RP), Transmission/Reception Point (TRP), Panel, Cell ', 'sector', 'cell group', 'carrier', 'elementary carrier' may be used interchangeably. The base station may be referred to by terms such as "macro cell", "small cell", "femto cell", "pico cell", etc., for example.

The base station may be configured to serve one or more (eg, three) cells. When a base station serves many cells, the entire coverage area of that base station can be divided into many smaller areas, in each of which communication services can be provided through subsystems of the base station, for example, small base stations for premises (remote radio units, English Remote Radio Head ). The term "cell" or "sector" refers to part or all of the coverage area of a base station and/or a subsystem of a base station providing communication services in that coverage area.

In the present disclosure, the terms "mobile station" (English Mobile Station, MS), "user terminal", "user device (UE)" and "terminal" can be used interchangeably.

A mobile station may be referred to as a subscriber station, mobile unit, subscriber unit, wireless unit, remote unit, mobile device, wireless device, wireless communication device, remote unit, mobile subscriber station, access terminal, mobile terminal, wireless terminal, remote terminal, telephone handset, user agent, mobile client, client, or, in some cases, other appropriate terms.

At least one of the base station and the mobile station may be called a transmitter, a receiver, a radio communication device, and so on. It should be appreciated that at least one of the base station and the mobile station may be a device mounted on a mobile unit, the mobile unit itself, and so on. The specified moving object can be a vehicle (for example, a car, an airplane, etc.), a moving object, the movement of which is carried out without a pilot on board (for example, a drone, a car without a driver, etc.) or a robot (controlled by human type or unmanned type). It should be appreciated that at least one of the base station and the mobile station also includes a device that does not necessarily move during a communication operation. For example, at least one of the base station and the mobile station may be an Internet of Things (IoT) device such as a sensor or the like.

The base station in the present disclosure can be interpreted as a user terminal. For example, each aspect/implementation of the present invention, instead of a configuration in which communication is carried out between a base station and a user terminal, can be applied to a configuration in which communication is carried out between a plurality of user terminals (for example, this type of communication may be called device communication). -to-Device, D2D), communication between a vehicle and a wide range of objects (Vehicle-to-Everything, V2X), etc.). In this case, the user terminals 20 may perform the functions of the base stations 10 described above. The words "upstream" and "downstream" may be interpreted as corresponding to terminal-to-terminal communications (eg, as "referring to direct communications"). For example, an uplink, a downlink, and the like may be interpreted as a direct link.

Similarly, in the present disclosure, a user terminal can be interpreted as a base station. In this case, the base station 10 may perform the functions of the user terminal 20 described above.

The actions described herein as being performed by a base station may, in some cases, be performed by older nodes. Obviously, in a network containing one or more network nodes with base stations, various operations performed to communicate with terminals can be performed by base stations, one or more network nodes other than base stations (for example, mobility management nodes (eng. Mobility Management Entity, MME), serving gateways (English Serving-Gateway, S-GW), etc., but this list is not limiting) or combinations of the listed nodes.

The aspects/implementations illustrated in this disclosure may be used singly or in combinations, which may vary depending on the preferred implementation. The order of operations, sequences, block diagrams, etc. used in this disclosure to describe aspects/implementations may be changed if this does not lead to inconsistencies. For example, while the various methods are illustrated in the present disclosure with various components of the steps in the order given by way of example, the specific order presented here is in no way limiting.

Aspects/implementations illustrated in this disclosure may apply to LTE, LTE-A, LTE-B, SUPER 3G, IMT-Advanced, fourth generation (4G) mobile communication system, fifth generation (5G) mobile communication system, future radio access (English Future Radio Access, FRA), new radio access technology (English New-Radio Access Technology, New-RAT), new radio system (English New Radio, NR), new radio access system (English New Radio Access, NX ), Future Generation Radio Access (FX), Global System for Mobile communications (GSM (registered trademark)), CDMA2000 system, Ultra-wideband mobile communication system ( Ultra Mobile Broadband, UMB), to IEEE 802.11 (Wi-Fi (registered trademark)), IEEE 802.16 (Wi-MAX (registered trademark)), IEEE 802.20, to a short distance communication system using broadband signals with extremely low spectral density Ultra-Wide Band, UWB), Bluetooth (registered trademark), systems using other suitable radio communication methods, and next generation systems developed from these systems. Multiple systems can be combined and used (eg combination of LTE or LTE-A and 5G, etc.).

In this disclosure, the phrase "based on" (or "based on") does not mean "only based on" (or "only based on"), unless otherwise indicated. In other words, the phrase "on the basis of" (or "on the basis of") means both "on the basis of" and "on the basis of at least" ("only on the basis of" and "at least on the basis of").

Referencing elements using designations such as "first", "second", etc. the present disclosure does not generally limit the number or order of these elements. These designations may be used in the present disclosure for convenience only, as a way to distinguish between two or more elements. Thus, the mention of the first and second elements does not imply that only two elements can be used, or that the first element must in any way precede the second element.

The term "decision" ("determination") in the present disclosure can cover a wide variety of activities. For example, “decision” (“determining”) can be interpreted as making decisions (carrying out checks) related to judgment, calculation, calculation, processing, inference, research, search, search and query (for example, search in a table, database or some other data structure), establishing a fact, etc.

Further, the term “decision” (“determining”) can be interpreted as meaning making decisions (carrying out checks) related to receiving (for example, receiving information), transmitting (for example, transmitting information), input, output, access (for example, access to data in memory), etc.

In addition, the term "decision" ("determining") in this document can be interpreted as meaning making decisions (carrying out checks) related to disambiguation, selection, selection, establishment, comparison, etc. In other words, “decision” (“determination”) can be interpreted as making decisions about the implementation (determining the need) for some action.

In addition, “decision” (“determination”) can be interpreted as “guess”, “expectation”, “consideration”, etc.

In this disclosure, the terms "connected", "connected" and any of their options means all direct or indirect connections or connections between two or more elements, and may allow the presence of one or more intermediate elements between two elements that are "connected" or "connected" between themselves. The relationship or connection between these elements may be physical, logical, or a combination of both. For example, "connection" can be interpreted as "access".

When the present disclosure indicates that two elements are connected, the two elements may be considered to be connected or interconnected using one or more electrical conductors, cables, and printed electrical connections, and, as a few non-limiting and non-exclusive examples, using electromagnetic energy, having wavelengths in radio frequency bands, microwave bands and optical (both visible and invisible) bands, or the like.

In the present disclosure, the expression "A and B are different" may mean "A and B are different from each other." It should be noted that this expression can mean "both A and B are different from C". The terms "separate", "be connected", etc. can be interpreted similarly to the term "various".

When used in the present disclosure, for example, terms such as "include", "comprising" and variations thereof, these terms should be understood in a content sense similar to that in which the term "comprising" is used. The conjunction "or" in this disclosure is not to be understood as meaning an exclusive disjunction.

In the present disclosure, when an article such as "a", "an" and "the" is added in English translation, the noun after the said article can be interpreted as containing the plural value as well.

Now, while the present invention has been described in detail above, it should be apparent to those skilled in the art that the invention according to the present disclosure is in no way limited to the implementations described in this disclosure. The invention according to the present disclosure can be carried out with various changes and in various modifications without deviating from the spirit and scope of the present invention as defined by the claims. Accordingly, the description of the present disclosure is provided for illustrative purposes only and should in no way be construed as limiting the present invention in any way.
