This may be given by applying transform precoding. .

[0015] An OFDM symbol may be a designation that includes a CP (Character Protection) attached to the OFDM symbol. In other words, an OFDM symbol may consist of the OFDM symbol itself and a CP attached to it.

[0016] Figure 1 is a conceptual diagram of a wireless communication system according to one embodiment of this model. In Figure 1, the wireless communication system comprises at least terminal devices 1A to 1C and a base station device 3 (BS#3: Base station#3). Hereinafter, terminal devices 1A to 1C will also be referred to as terminal device 1 (UE#1: User Equipment#1).

[0017] The base station device 3 may consist of one or more transmitting devices (or a transmitting point, a transceiver, and a transceiver). If the base station device 3 consists of multiple transmitting devices, each of the multiple transmitting devices may be located in a different position.

A serving cell may consist of one or both of two or more downlink component carriers and two or more uplink component carriers. Downlink component carriers and uplink component carriers are also collectively referred to as component carriers (carriers).

[0020] For example, one resource grid may be provided for each component carrier. Alternatively, one resource grid may be provided for each set of component carriers and a subcarrier spacing configuration μ. Here, the subcarrier spacing configuration μ is also called numerology. For example, one resource grid may be provided for a set of an antenna port p, a subcarrier spacing configuration μ, and a transmission direction x.

A wireless frame consists of 10 subframes. The length of a subframe is T. sf =(Δf max N f / 1000)·T s = 1ms. The number of OFDM symbols per subframe is N. subframe,μ symb =N slot symb N subframe,μ slot That is the case.

[0030] A slot may consist of multiple OFDM symbols, for example, N consecutive symbols. slot symb A single OFDM symbol may constitute one slot. For example, a normal CP In the settings, N slot symb =14 is also acceptable. Furthermore, in the settings for extended CP, N slot symb =12 is also acceptable.

For example, slot index n μ s In the subframe, the range is from 0 to N subframe,μ slot The integer values ​​may be given in ascending order within the range of -1. For setting the rear spacing μ, the number and index of slots included in the wireless frame may be given.

For example, a channel may correspond to a physical channel. A symbol may correspond to an OFDM symbol. A symbol may correspond to a resource block unit. A symbol may correspond to a resource element.

Here, the large-scale characteristics may include at least the long-interval characteristics of the channel. The large-scale characteristics include at least some or all of the delay spread, Doppler spread, Doppler shift, average gain, average delay, and some or all of the spatial Rx parameters. That's fine. The first and second antenna ports are QCL with respect to beam parameters if the received beam assumed by the receiver for the first antenna port and the second antenna port are QCL. The receiving beam assumed by the receiving side for the antenna port may be the same (or corresponding) as the receiving beam. The first antenna port and the second antenna port are QCL with respect to beam parameters if the transmitting beam assumed by the receiving side for the first antenna port and The transmission beam assumed by the receiving side for the second antenna port may be the same (or corresponding).

The fact that the Naport is QCL of type B is symbolic in one antenna port. The second large-scale characteristic of the channel on which the symbol is transmitted may be inferred from the channel on which the symbol is transmitted at another antenna port. The fact that two antenna ports are QCLs (with respect to type C) may be inferred from the third large-scale characteristic of the channel on which the symbol is transmitted at one antenna port. The fact that two antenna ports are QCLs (with respect to type D) may be inferred from the fourth large-scale characteristic of the channel on which the symbol is transmitted at one antenna port. The first large-scale characteristic may include all of the Doppler shift, Doppler spread, mean delay, and delay spread. The second large-scale characteristic may include all of the Doppler shift and Doppler spread. The third large-scale characteristic may include all of the Doppler shift and mean delay. The fourth large-scale characteristic may include spatial reception parameters (spatial direction information, beam information). The antenna port for DMRS may be a DMRS port.

The terminal device 1 may recognize that it can receive the PDSCH without switching the active downlink BWP, based on detecting the DCI format 1_0 used for scheduling the PDSCH.

[0156] DCI format 1_1 is used for scheduling PDSCHs located in a given cell. DCI format 1_1 is used for less than some or all of 4A to 4I. It is composed of including the above. 4A) DCI Format Specific Fields 4B) Frequency Domain Resource Allocation Field 4C) Time Domain Resource Allocation Field 4E) MCS Field 4F) PDSCH_HARQ Feedback Timing Indicator Field 4G)PUCCH resource instruction field 4H) BWP Field 4I) Carrier Indicator Field

[0157] The DCI format specific field included in DCI format 1_1 may indicate 1.

[0158] The frequency domain resource allocation field included in DCI format 1_1 may be used to indicate the allocation of frequency resources for PDSCH.

[0159] The time domain resource allocation field included in DCI format 1_1 may be used to indicate the allocation of time resources for PDSCH.

[0160] The MCS field included in DCI format 1_1 is the modulation scheme for PDSCH, and This may be used to indicate at least one or both of the target coding rates.

[0161] If DCI format 1_1 includes a PDSCH_HARQ feedback timing indicator field, the PDSCH_HARQ feedback timing indicator field extends from the slot containing the last OFDM symbol of the PDSCH to the slot containing the first OFDM symbol of the PUCCH. This may be used to indicate the offset. If DCI format 1_1 does not include the PDSCH_HARQ feedback timing indicator field, the offset from the slot containing the last OFDM symbol of the PDSCH to the slot containing the first OFDM symbol of the PUCCH may be determined by a parameter in the upper layer.

[0162] The PUCCH resource reference field may be a field that indicates the index of one or more PUCCH resources included in the PUCCH resource set.

[0163] The BWP field of DCI format 1_1 is used in the schedule according to DCI format 1_1. It may be used to indicate the downlink BWP on which the PDSCH being linked is located. In other words, DCI format 1_1 may involve a change in the active downlink BWP. Terminal device 1 may recognize the downlink BWP on which the PUSCH is located, based on detecting the DCI format 1_1 used for scheduling the PDSCH.

[0164] DCI format 1_1, which does not include the BWP field, indicates a change in the active downlink BWP. It may also be a DCI format that schedules PDSCH without BWP. Terminal device 1 is a DCI format 1_1 used for scheduling PDSCH, and BWP Based on detecting DCI format 1_1 that does not include a field, active downlink It is acceptable to recognize that the PDSCH is being received without switching the link BWP.

[0165] DCI format 1_1 includes a BWP field, but terminal device 1 is DCI format If the BWP switching function by 1_1 is not supported, the BWP field may be ignored by terminal device 1. In other words, terminal device 1 that does not support the BWP switching function , DCI format 1_1 used for scheduling PDSCH, and BWP format Based on the detection of DCI format 1_1 including the field, it may be recognized that the PDSCH can be received without switching the active downlink BWP. Here, terminal device 1 If the terminal device supports the BWP switching function, the RRC layer's function information reporting procedure may report that "Terminal device 1 supports the BWP switching function."

[0166] If DCI format 1_1 includes a carrier indicator field, the carrier The rear indicator field is the downlink component carrier where the PDSCH is located. It may be used to indicate A. DCI format 1_1 carrier indicator If no field is included, the downlink component carrier where the PDSCH is located is, A PDCCH containing DCI format 1_1, which is used for scheduling the PDSCH, is configured. It may be the same as the downlink component carrier. If the number of downlink component carriers set on terminal device 1 in a serving cell group is 2 or more (when downlink carrier aggregation is operated in a serving cell group), the scheduler of the PDSCH placed in that serving cell group The carrier indicator field included in DCI format 1_1 used in the game The number of bits may be 1 or more (for example, 3 bits). If the number of downlink component carriers set on terminal device 1 in a serving cell group is 1 (i.e., downlink carrier aggregation is not operated in a serving cell group), the scheduler of the PDSCH placed in that serving cell group Carrier indicator field included in DCI format 1_1 used for ing The number of bits may be 0 bits (or the DCI format 1_1 used for scheduling PDSCHs placed in a given serving cell group may not include a carrier indicator field).

[0167] PDSCH may be transmitted to transmit transport blocks. PDSCH may be used to transmit transport blocks delivered from DL-SCH. PDSCH may be used to transmit transport blocks. Transport blocks may be placed on PDSCH. Transport blocks corresponding to DL-SCH are on PDSCH. They may be arranged. Base station device 3 may transmit PDSCH. Terminal device 1 may receive PDSCH.

[0168] Downlink physical signals may correspond to a set of resource elements. Downlink physical signals do not need to carry information generated in higher layers. Downlink physical signals may be physical signals used in the downlink component carrier. Downlink physical signals may be transmitted by base station device 3. Downlink physical signals may be transmitted by terminal device 1. In a wireless communication system according to one aspect of this embodiment, at least some or all of the following downlink physical signals are used. It's okay if it's done that way. ·Synchronization signal (SS) ·DL DMRS(DownLink DeModulation Reference Signal) ·CSI-RS(Channel State Information-Reference Signal) ·DL PTRS(DownLink Phase Tracking Reference Signal)

[0169] The synchronization signal may be used to synchronize the terminal device 1 in either the frequency domain or the time domain of the downlink, or both. The synchronization signal is a general term for PSS (Primary Synchronization Signal) and SSS (Secondary Synchronization Signal).

[0170] Figure 7 shows an example of the configuration of an SS / PBCH block according to one aspect of this embodiment. In Figure 7, the horizontal axis is the time axis (OFDM symbol index l sym ) and the vertical axis represents the frequency domain. Block 700 also shows the set of resource elements for PSS. Block 720 shows a set of resource elements for SSS. Also, four blocks Blocks 710, 711, 712, and 713 represent a set of resource elements for a PBCH and a DMRS for the PBCH (DMRS associated with the PBCH, DMRS contained within the PBCH, and DMRS corresponding to the PBCH).

[0171] As shown in Figure 7, the SS / PBCH block contains PSS, SSS, and PBCH. The SS / PBCH block also contains four consecutive OFDM symbols. The SS / PBCH block contains 240 subcarriers. PSS is the 57th to 183rd subcarriers in the first OFDM symbol. It is placed on the subcarrier. SSS is from the 57th to the 183rd OFDM symbol in the third OFDM symbol. It is placed in the nth subcarrier. Subcarriers 1 through 56 of the first OFDM symbol may be set to zero. Subcarriers 184 through 240 of the first OFDM symbol may be set to zero. Subcarriers 49 through 56 of the third OFDM symbol may be set to zero. Subcarriers 184 through 192 of the third OFDM symbol may be set to zero. The PBCH is placed in subcarriers 1 through 240 of the second OFDM symbol, where a DMRS for the PBCH is not placed. The PBCH is placed in subcarriers 1 through 48 of the third OFDM symbol, where a DMRS for the PBCH is not placed. The PBCH is placed in subcarriers 193 through 240 of the third OFDM symbol, where a DMRS for the PBCH is not placed. The PBCH is placed on the subcarriers from the 1st to the 240th subcarrier of the 4th OFDM symbol, where a DMRS for the PBCH is not located.

[0172] The antenna ports for PSS, SSS, PBCH, and DMRS for PBCH may be the same.

[0173] The PBCH whose symbol is transmitted at a given antenna port may be estimated by a DMRS for the PBCH located in the slot to which the PBCH is mapped, and which is included in the SS / PBCH block containing the PBCH.

[0174] DL DMRS is a general term for DMRS for PBCH, DMRS for PDSCH, and DMRS for PDCCH.

[0175] The set of antenna ports for DMRS for PDSCH (DMRS associated with PDSCH, DMRS included in PDSCH, DMRS corresponding to PDSCH) is given based on the set of antenna ports for said PDSCH. It may be obtained. In other words, the set of antenna ports for a DMRS for a PDSCH may be the same as the set of antenna ports for the PDSCH.

[0176] The transmission of PDSCH and the transmission of DMRS for said PDSCH are indicated by a single DCI format. This may be done (or scheduled). The PDSCH and the DMRS for the PDSCH may be collectively referred to as the PDSCH. Transmitting a PDSCH may be done by transmitting the PDSCH and the DMRS for the PDSCH.

[0177] The propagation path of a PDSCH may be estimated from the DMRS for that PDSCH. A set of resource elements on which the signal is transmitted, and a DMRS symbol for the PDSCH. If the set of resource elements on which the symbol is transmitted belongs to the same Precoding Resource Group (PRG), the PDSCH on which the symbol of that PDSCH is transmitted at a given antenna port may be estimated by the DMRS for that PDSCH.

[0178] The antenna port for the DMRS for PDCCH (DMRS associated with PDCCH, DMRS included in PDCCH, DMRS corresponding to PDCCH) may be the same as the antenna port for PDCCH.

[0179] PDCCH may be inferred from the DMRS for that PDCCH. That is, the propagation path of a PDCCH may be inferred from the DMRS for that PDCCH. If the symbol of a certain PDCCH is transmitted, A set of elements and a resource on which the DMRS symbol for the PDCCH is transmitted. When the same precoder is applied (or is assumed to be applied) to a set of elements, the symbol of that PDCCH at a certain antenna port is transmitted. The PDCCH may be estimated by the DMRS for the PDCCH.

[0180] BCH (Broadcast Channel), UL-SCH (Uplink-Shared Channel), and DL-SCH (Downlink-Shared Channel) are transport channels. Transport channels define the relationship between physical layer channels and MAC layer channels (also called logical channels). do.

[0181] The BCH in the transport layer is mapped to the PBCH in the physical layer. In other words, the transport layer Transport blocks passing through the BCH are delivered to the PBCH in the physical layer. The UL-SCH in the transport layer is mapped to the PUSCH in the physical layer. In other words, transport blocks passing through the UL-SCH in the transport layer are delivered to the PUSCH in the physical layer. Also, the DL-SCH in the transport layer is mapped to the PDSCH in the physical layer. In other words, the DL-SCH in the transport layer The transport blocks that pass through are delivered to the PDSCH in the physical layer.

[0182] Each serving cell may be provided with one UL-SCH and one DL-SCH. BCH may be provided to the PCell. BCH may not be provided to the PSCell or SCell.

[0183] At the MAC layer, HARQ (Hybrid Automatic Repeat request) control is performed for each transport block.

[0184] BCCH (Broadcast Control Channel), CCCH (Common Control Channel), and DCCH (Dedicated Control Channel) are logical channels. For example, BCCH is MIB. Alternatively, it is a channel in the RRC layer used to transmit system information. Also, CCCH The Common Control Channel transmits a common RRC message across multiple terminal devices. It may be used for the purpose of... Here, CCCH is, for example, a terminal device that is not connected to RRC. It may be used for 1. Also, DCCH (Dedicated Control Channel) is a terminal device It may be used at least to send a dedicated RRC message to 1. Here, DCCH This may be used, for example, for terminal device 1 that is connected via RRC.

[0185] Terminal device 1 may transmit or receive higher-layer parameters. Terminal device 1 may transmit or receive a message containing higher-layer parameters. The message is an RRC message. It may be either a GI or MAC CE. The upper layer parameters may also be RRC parameters.

[0186] Higher-level parameters common to multiple terminal devices 1 are also called common higher-level parameters. Here, common higher-level parameters may be defined as parameters specific to a serving cell. Here, parameters specific to a serving cell are parameters common to the terminal devices (e.g., terminal devices 1-A, B, C) on which the serving cell is set. That's fine.

[0187] For example, common upper-layer parameters may be included in the RRC message delivered to BCCH. For example, common upper-layer parameters may be included in the RRC message delivered to DCCH. .

[0188] Among the upper-level parameters, those that differ from common upper-level parameters are also called dedicated upper-level parameters. Here, dedicated upper-level parameters can provide dedicated RRC parameters for terminal device 1-A on which a serving cell is configured. In other words, dedicated RRC parameters are upper-level parameters that can provide unique settings for each of terminal devices 1-A, B, and C.

[0189] The BCCH of a logical channel is mapped to the BCH of the transport layer or the DL-SCH. For example, a transport block containing MIB information is delivered to the BCH of the transport layer. Also, a transport block containing system information that is not an MIB is delivered to the transport layer. It is delivered to DL-SCH in the T layer. Also, CCCH is mapped to DL-SCH or UL-SCH. Transport blocks mapped to CCCH are delivered to DL-SCH or UL-SCH. Similarly, DCCH is mapped to DL-SCH or UL-SCH. In other words, transport blocks mapped to DCCH are delivered to DL-SCH or UL-SCH.

[0190] An RRC message contains one or more parameters managed in the RRC layer. These parameters are also referred to as RRC parameters. For example, RRC Messages may include MIBs. RRC messages may also include system information. Furthermore, RRC messages may include messages corresponding to CCCHs. RRC messages may also include messages corresponding to DCCHs. RRC messages containing messages corresponding to DCCHs are also referred to as individual RRC messages.

[0193] Cell search is a procedure used by terminal device 1 to synchronize with a cell in the time domain and frequency domain and to detect its physical cell identity. In other words, terminal device 1 may use cell search to synchronize with a cell in the time domain and frequency domain and detect its physical cell identity.

[0194] The PSS series is assigned based on at least the physical cell ID. The SSS series is assigned based on the physical cell ID. It is given based on at least that.

[0195] SS / PBCH block candidates indicate resources that are permitted (possible, reserved, configured, specified, or potentially) to send SS / PBCH blocks.

[0196] A set of SS / PBCH block candidates in a half-wireless frame is also called an SS burst set. An SS burst set is a transmission window. It is also called the SS transmission window or the Discovery Reference Signal transmission window. An SS burst set is a general term that includes at least the first SS burst set and the second SS burst set.

[0197] The base station device 3 transmits SS / PBCH blocks of one or more indices at predetermined intervals. The terminal device 1 may detect at least one of the SS / PBCH blocks of the one or more indices and attempt to decode the PBCH contained in the SS / PBCH block.

[0198] A random access (random access procedure) is a procedure that includes at least some or all of messages 1, 2, 3, and 4. A random access procedure may be triggered in response to a request for PRACH transmission by higher-layer parameters or PDCCH order.

[0199] Message 1 is the procedure for sending PRACH by terminal device 1. Terminal device 1 sends a random access preamble in PRACH as message 1. Terminal device 1 sends PRACH in one PRACH opportunity selected from one or more PRACH opportunities based on at least the index of SS / PBCH block candidates detected based on cell search. I believe. Each PRACH opportunity is determined based on at least time-domain and frequency-domain resources. To be justified.

Message 2 is the procedure for terminal device 1 to attempt to detect DCI format 1_0 with a CRC (Cyclic Redundancy Check) scrambled with RA-RNTI (Random Access - Radio Network Temporary Identifier). Terminal device 1 performs a cell search. Based on the detected SS / PBCH block, the control is given based on the MIB contained in the PBCH. An attempt is made to detect a PDCCH containing the DCI format in the resources indicated based on the settings of the resource set and the search area set. Message 2 is also called a Random Access Response (RAR). Terminal device 1 may receive a Random Access Response (or a Random Access Response message) with a PDCCH / PDSCH as a message.

[0202] Message 3 is included in DCI format 1_0 detected by the Message 2 procedure. Send a PUSCH scheduled by a random access response grant. This is the procedure. Here, random access response grant The grant is indicated by the MAC CE included in the PDSCH scheduled according to the DCI format 1_0.

[0207] In data communication, terminal device 1 attempts to detect PDCCH in resources identified based on the control resource set and the search area set (monitor PDCCH, PDCCH (Monitor).

[0208] A control resource set (CORESET) is a set of a predetermined number of resource blocks. This is a set of resources consisting of a predetermined number of OFDM symbols. In the frequency domain, the control resource set may consist of continuous resources (non-interleaved mapping) or distributed resources (interleaver mapping).

[0209] The set of resource blocks that constitute the control resource set may be indicated by a higher-level parameter. The number of OFDM symbols that constitute the control resource set may also be indicated by a higher-level parameter.

[0210] Terminal device 1 attempts to detect PDCCH in the search area set. Here, the search area set Attempting to detect PDCCH in the search domain set may also mean attempting to detect candidate PDCCHs in the search domain set, or attempting to detect DCI formats in the search domain set. It may be either a good idea or an attempt to detect PDCCH in the control resource set. Alternatively, you could try to detect candidates for PDCCH in the control resource set. Alternatively, an attempt may be made to detect the DCI format in the control resource set.

[0211] A search space set is defined as a set of candidate PDCCHs. A search space set may be a CSS (Common Search Space) set or a USS (UE-specific Search Space) set. Terminal device 1 may be part of a Type 0 PDCCH common search space set, a Type 0a PDCCH common search space set, a Type 1 PDCCH common search space set, a Type 2 PDCCH common search space set, a Type 3 PDCCH common search space set, and / or a UE-specific search space set. We attempt to detect PDCCH candidates in all cases.

[0212] The Type 0PDCCH common search region set is used as the common search region set for index 0. It is permissible to stay there. The Type 0PDCCH common search area set is the common search area at index 0. It's fine as a set.

That is, the scheduling that is set is the same as the scheduling that is set The scheduling type may be either scheduling type 1 or scheduling type 2. The PUSCH transmission for scheduling type 1 may be set semi-statically. For example, the PUSCH transmission for scheduling type 1 may operate in response to the reception of a certain upper-layer parameter.

For example, terminal device 1 And either or both of the base station equipment 3 direct radio waves into a specific space by beamforming. Reception may be from either direction. For one or both of the transmission and reception of radio waves, one or Multiple antennas may be provided and used. Directional radio waves may be called beams. Information related to beams may be called beam information. For example, beam information may be a specific spatial direction. For example, beam information may be the direction of arrival of radio waves. Beam information may be TCI status. Beam information may be uplink It may also be a link transmission space filter. Beam information may also be an SRS resource instruction. The beam information may be based on the assumption of QCL, or may be related to QCL.

[0241] Terminal device 1 may receive PDSCH. Base station device 3 may transmit PDSCH. One transmission method may be defined for PDSCH. One transmission method may be used for all PDSCH transmissions.

[0242] Terminal device 1 may perform reception in PDSCH. Base station device 3 may perform transmission in PDSCH. One transmission method may be transmission method 1. In transmission method 1, it may be assumed that transmission in PDSCH is performed at up to 8 layers. Each layer may be mapped to one or more antenna ports. One or more antenna ports are antenna ports It may be part or all of antenna ports 1000-1023. For example, if no extended CSI ports are configured, one or more antenna ports may be part or all of antenna ports 1000-1023. For example, if extended CSI ports are configured, one or more antenna ports may be part or all of antenna ports 1000-1127.

[0243] Terminal device 1 may schedule to receive PDSCH. For example, terminal device 1 may schedule to receive PDSCH by DCI. PDSCH reception may be scheduled by the DCI format in PDCCH. PDSCH may be scheduled in DCI format. Terminal device 1 may schedule grand The token may be received in DCI format. If a scheduling grant is received, Downlink resource allocation may be used.

[0244] Terminal device 1 may have the upper-layer parameter TCI-State set. For example, terminal device 1 A list may be set in the upper layer parameter PDSCH-Config. The list may contain up to M upper layer parameters TCI-State. The list may also be a list of up to M upper layer parameters TCI-State. Terminal device 1 may have a list set to decode (receive) the PDSCH according to the PDCCH with DCI. M may depend on the terminal capability (UE capability). For example, M may depend on the terminal capability maxNumberConfiguredTCIStatePerCC. TCI-State may also be referred to as TCI state.

[0245] Each TCI-State is a place to set up a QCL (QCL relationship: Quasi co-location relationship) Lameter may be included. The QCL relationship may be a relationship between one or two downlink reference signals (downlink physical signals) and the DMRS (DMRS port) of the PDSCH. The QCL relationship may be one or two In relation to the downlink reference signal (downlink physical signal) and the PDCCH's DMRS (DMRS port) It may exist. QCL relationships involve one or two downlink reference signals (downlink physical signals). This could also be a relationship between a CSI-RS resource and a CSI-RS (CSI-RS port). For example, a chat The QCL relationship between channel / signal A and channel / signal B may also represent that channel / signal A is QCL with channel / signal B.

[0246] QCL relationships are either or both of the upper layer parameter qcl-Type1 and the upper layer parameter qcl-Type2. It may be set by the method. For example, the QCL relationship is the upper layer parameter qcl-Type1 for the first downlink reference signal (DL RS) and the upper layer parameter for the second downlink reference signal The first downlink reference signal and may be set by either or both of the following. If the second downlink reference signal is different, the QCL type of qcl-Type1 does not have to be the same as the QCL type of qcl-Type2. The QCL type corresponding to each downlink reference signal may be given by the upper-layer parameter qcl-Type in the upper-layer parameter QCL-Info. The QCL type may be one of typeA, typeB, typeC, and typeD.

[0247] One list may be set by the upper-level parameter dlOrJointTCI-StateList. For example, one list may be set in the upper-level parameter PDSCH-Config. One list may contain up to 128 upper-level parameters TCI-State. One list may contain up to 128 It may be a list of up to 128 upper-layer parameter TCI-States. One list may be set to provide one reference signal. The upper-layer parameter TCI-State may be set to provide one reference signal. One reference signal is DMRS of PDSCH and PDCCH The reference signal for QCL for DMRS may be one reference signal for CSI-RS. One list may be set to provide one reference. The upper layer parameter TCI-state may be set to provide one reference. One reference is the uplink transmit spatial filter (UL TX spatial filter). It may be used to determine the uplink transmit space filter. The uplink transmit space filter may be used for PUSCH, PUCCH, and SRS. That is, one reference may be provided to determine the uplink transmit space filter for PUSCH, PUCCH, and SRS. The TCI-State may be referred to as the DL / Joint TCI state or the Unified TCI state. The upper layer parameter dlOrJointTCI-StateList being set means that the Unified TCI state is It may also be set. Setting the upper-level parameter dlOrJointTCI-StateList may mean that a unified TCI state is set.

[0248] TCI-State (e.g., upper layer parameter TCI-State), and TCI-UL-State (e.g., upper layer parameter TCI-State) The tier parameter TCI-UL-State may be set in one BWP of one component carrier. If TCI-State is not set, or if TCI-UL-State is not set in one BWP... In addition, terminal device 1 sets the TCI-State from the reference BWP, or sets the TCI-UL-State. The following may be applied. TCI-UL-State may also be referred to as UL TCI state or unified TCI state. Good. Setting ul-TCI-StateList means setting a unified TCI state. good.

[0249] Terminal device 1 has both the first upper layer parameter and the second upper layer parameter set. You do not need to expect this. The first upper-level parameter may be any of tci-StatesToAddModList, SpatialRelationInfo, and PUCCH-SpatialRelationInfo. The second upper-level parameter may be any of dl-OrJointTCI-StateList and TCI-UL-StateList. Any of the following may be true. If tci-StatesToAddModList is set on any component carrier in a certain list, the second upper layer parameter does not need to be set on any component carrier in the same band in that list. The certain list is a list of upper layer parameters simultaneousTCI-UpdateList1, simultaneousTCI-UpdateList2, simultaneousSpatial-UpdatedList1, and Alternatively, it may be set by the higher-level parameter `simultaneousSpatial-UpdatedList2`.

[0250] Terminal device 1 may receive an activation command. The code is used to map up to eight "TCI states, and one or both of a pair of TCI states" to code points in the DCI field 'Transmission Configuration Indication'. A pair of TCI states may consist of one or both of the following: one TCI state for a downlink channel / signal and one TCI state for an uplink channel / signal. An activation command may be used to map up to eight sets of TCI states to code points in the DCI field 'Transmission Configuration Indication'. Each set may contain up to two TCI states for the uplink and downlink channels / signals. Activation command For downlink channels / signals, up to two TCI states and up to two TCI states for uplink channels / signals may be used to map to code points in the DCI field 'Transmission Configuration Indication'. The TCI state may also be referred to as the DL TCI state. TCI for uplink channel / signal The state may also be referred to as the UL TCI state. Downlink channel / signal is PDSCH, PDCCH, And, it may be part or all of CSI-RS. The uplink channel / signal may be part or all of PUSCH, PUCCH, and SRS. DCI (DCI format) may consist of one or more DCI fields. For example, DCI (DCI format) may consist of a TCI field ('Transmission Configuration Indication' field).

[0251] If the first set of one or more TCI state IDs is activated in the second set, the first set is suitable for the downlink BWP in the indicated component carrier. It may be used. If the first set of one or more TCI state IDs is activated in the third set, the first set may be applied for the downlink BWP and uplink BWP in the indicated component carrier. The second set may be applied for one or more components A third set may be one or both of the component carrier and one or more downlink BWPs. A third set may be some or all of the component carrier, one or more downlink BWPs, and one or more uplink BWPs.

[0252] The activation command sets either the DL / Joint TCI state or the UL TCI state to a single TCI code point (the code in the DCI field 'Transmission Configuration Indication'). When mapping to a point, terminal device 1 may apply either or both of the indicated DL / Joint TCI state and the indicated UL TCI state.

[0253] Terminal device 1 provides the specified DL / Joint TCI state or the specified UL TCI state. A DCI format may be received. The DCI format does not need to include a downlink assignment. For example, if the DCI format does not include a downlink assignment. Terminal device 1 is configured such that CS-RNTI is used to scramble the CRC for DCI, all RV (Redundancy version) values ​​are 1, all MCS values ​​are 1, and NDI is 0. It may be assumed that some or all of the following are true: all zeros are set for FDRA type 0, and all ones are set for FDRA type 1.

[0254] Terminal device 1 may receive higher layer settings. Terminal device 1 is the first to receive the “TCI state to be set”. After receiving the higher layer settings, and from the “configured TCI state”, one “instructed TCI state” Before the "state" is applied, terminal device 1 may assume that the DMRS of the PDSCH, the DMRS of the PDCCH, and the CSI-RS to which the "instructed TCI state" is applied are the SS / PBCH block and the QCL. The setting of the upper layer parameter DLorJoint-TCIStateList means that the "TCI state to be set" The "state" may be set. Setting the upper-level parameter DLorJoint-TCIStateList may mean that a unified TCI state is set. Setting the "TCI state to be set" may mean that a unified TCI state is set. DLorJoint-TCIStateList may be accompanied by multiple upper-level parameters TCI-State.

[0255] After terminal device 1 receives the first upper-layer setting of “Set TCI State”, and before one “Instructed TCI State” is applied from “Set TCI State”, terminal device 1 may assume that the first uplink transmit space filter for PUSCH, PUCCH, and SRS to which the “Instructed TCI State” is applied is the same as the second uplink transmit space filter. The second uplink transmit space filter may be the uplink transmit space filter for PUSCH transmissions scheduled by random access response grants in the Initial access procedure. Setting the upper-layer parameter ul-TCI-StateList may mean setting “Set TCI State”. Setting the upper-layer parameter ul-TCI-StateList may mean setting a unified TCI state. It may also be the case that the “TCI state to be set” is set, which may also be the case that a unified TCI state is set. ul-TCI-StateList contains multiple upper-level parameter TCI-States. It may be accompanied.

[0256] Terminal device 1 may receive higher layer settings. Terminal device 1 is the first to receive the “TCI state to be set”. After receiving the higher-level settings as part of a synchronized reconfiguration, and the "TCI state to be set" Before one “indicated TCI state” is applied, apply the indicated TCI state. The DMRS of PDSCH, the DMRS of PDCCH, and CSI-RS are SS / PBCH blocks, or CSI-RS Resources and QCLs may also be identified. For example, an SS / PBCH block or a CSI-RS resource may be identified in a random access procedure initiated by a synchronized reconfiguration.

[0257] Terminal device 1 may receive higher layer settings. Terminal device 1 is the first to receive the “TCI state to be set”. After receiving the higher-level settings as part of a synchronized reconfiguration, and the "TCI state to be set" Before one “indicated TCI state” is applied, apply the indicated TCI state. The first uplink transmit space filter for PUSCH, PUCCH, and SRS is the second It may be assumed that this is the same as the uplink transmit space filter. The second uplink transmit space filter is the uplink space filter for PUSCH transmits scheduled by the Random Access Response Grant (RAR UL grant) in the Random Access Procedure. The second uplink transmit space filter may be an uplink transmit space filter for push transmissions scheduled by random access response grants in a random access procedure initiated by a synchronized reset.

[0258] When terminal device 1 receives a setting of “Set TCI State” accompanied by one TCI state, terminal device 1 may obtain a QCL assumption from the Set TCI State. The Set TCI State may be a TCI state for the CSI-RS, PDSCH DMRS, and PDCCH DMRS to which the indicated TCI state applies. The Set TCI State may also be the upper-layer parameter dl-OrJointTCI-StateList.

[0259] When terminal device 1 receives a “configured TCI state” configuration with one TCI state, terminal device 1 may determine the uplink transmit space filter from the configured TCI state. The configured TCI state may be a TCI state for PUSCH, PUCCH, and SRS to which the indicated TCI state applies. The configured TCI state may be a higher-layer parameter dl-OrJointTCI-StateList or ul-TCI-StateList.

[0260] If a unified TCI state is set, and terminal device 1 transmits the first channel, and the first “indicated TCI state” is different from the second “indicated TCI state”, the first “indicated TCI state” may be applied from the first slot. The first channel may be a PUCCH with HARQ-ACK information, or a PUSCH with HARQ-ACK information. HARQ-ACK The information transmits a TCI state indication without a downlink assignment. The HARQ-ACK information may correspond to the DCI. The HARQ-ACK information may correspond to the PDSCH scheduled by the DCI that transmits the TCI status indication. Second The TCI state indicated by the first may be indicated before the first indicated TCI state. The first slot may be the first slot at least beamAppTime symbols after the last OFDM symbol of the first channel. BeamAppTime may be the number of OFDM symbols. BeamAppTime may be set by higher-level parameters. BeamAppTime may be determined by terminal capabilities. The indicated TCI state may be an indicated TCI-State or an indicated TCI-UL-State.

[0261] When multi-DCI mode is set, terminal device 1 will have a relationship with each CORESET pool index The system may receive activation commands ("TCI states to be activated") for the associated CORESET. The activation commands may be used to map up to eight TCI states to code points in the DCI field 'Transmission Configuration Indication'. A TCI state mapped to a dot point may also be referred to as an activated TCI state. A TCI state indicated by an activation command may also be referred to as an activated TCI state. When a set of TCI state IDs is activated for a CORESET pool index, the “activated TCI state” corresponding to that one CORESET pool index may also be associated with a physical cell ID and a different CORESET pool index from that one CORESET pool index. The corresponding “activated TCI state” may be associated with a physical cell ID different from that one physical cell ID. The activation command may be received as MAC CE. In one BWP, one or Multiple CORESETs may be configured. One CORESET may correspond to a CORESET pool index of '0' or '1'. The setting of multi-DCI mode is a higher-tier process. The parameter PDCCH-Config may contain two different values ​​for the CORESET Pool Index (or coresetPoolIndex).

[0262] DCI field 'TransmissionConfiguration Indication' (i.e., TCI field) A single code point may contain up to two TCI states. Terminal device 1 may receive an activation command. An activation command is a combination of up to eight TCI states of two or fewer states. This may be used to map to a code point in the DCI field 'Transmission Configuration Indication'. Terminal device 1, in the activation command, has more than 8 TCI conditions You don't need to expect to receive a state.

[0263] When terminal device 1 transmits the first PUCCH in the first slot, the TCI state and code point The mapping with the input may be applied from the second slot. The first PUCCH is the first This may be accompanied by HARQ-ACK information. The first PUCCH may be transmitted in response to the first PDSCH. The first PDSCH may transmit an activation command.

[0264] If a TCI field exists, and the time offset is greater than or equal to a threshold, and after the initial setting of the TCI state has been received and before the activation command has been received, terminal device 1 may assume that the DMRS of a PDSCH in one serving cell is QCL with respect to the SS / PBCH block and QCL type A. The existence of a TCI field may also mean that the upper layer parameter tci-PresentInDCI is set to 'enabled'. The existence of a TCI field may also mean that the upper layer parameter tci-PresentDCI-1-2 is set for CORESET to schedule the PDSCH. The time offset may be the offset between the reception of the DL DCI and the PDSCH. The threshold may be timeDurationForQCL. The threshold can be based on the reported terminal capabilities.

[0265] If the first upper-layer parameter is set, terminal device 1 may assume that the DCI format of the PDCCH transmitted in CORESET contains a TCI field. The higher-level parameter may be tci-PresentInDCI, which is set to 'enabled'. The first upper-layer parameter may be tci-PresentInDCI, which is set to 'enabled' for PDSCH or CORESET, which schedules multicast PDSCH. The upper layer parameter may be tci-PresentDCI-1-2.

[0266] If the TCI field does not exist and the time offset is greater than or equal to the threshold, the TCI state or QCL assumption for the PDSCH is used to determine the PDSCH antenna port QCL. Even if it is the same as the TCI state or QCL assumption applied for CORESET used for that purpose The time offset is the time offset between the reception of the DL DCI and the corresponding PDSCH. This is also acceptable. The threshold can be timeDurationForQCL.

[0267] If an SFN is configured for PDCCH, and an SFN is configured for PDSCH, and PDSCH is scheduled in DCI format, and the time offset is greater than or equal to the threshold, and the default beam is supported, then the PDSCH The QCL assumption or TCI state is the QCL assumption or TCI state that applies to CORESET. It may be the same as the state. Also, if dynamic switching is not supported, CORESET may be activated in two TCI states. CORESET is CORESET for receiving DL DCI. It may be assumed that a TCI field exists if an SFN is set for PDCCH, and an SFN is set for PDSCH, and PDSCH is scheduled in DCI format, and the time offset is greater than or equal to a threshold, and the default beam is not supported. This may also mean that the upper-level parameter sfnSchemePdcch is set. Setting SFN means that the upper layer parameter sfnSchemePdsch is set. The DCI format may be any of DCI format 1_0, DCI format 1_1, or DCI format 1_2. The default beam may be sfn-DefaultDL-BeamSetup for DCI without a TCI field. The time offset may be the time offset between the reception of the DL DCI and the corresponding PDSCH. The threshold is timeDurationForQCL That's fine.

[0268] If an SFN is set for PDSCH, and an SFN is not set for PDCCH, and PDSCH is scheduled according to DCI format 1_1 / 1_2, and time If the offset is greater than or equal to the threshold, the presence of a TCI field may be expected.

[0269] If PDSCH is scheduled by DCI format 1_0 / 1_1 / 1_2, and SFN method A is set for PDCCH, and SFN is not set for PDSCH, and there are no TCI code points (code points in the TCI field) with two TCI states, and the time offset is greater than or equal to a threshold, and the CORESET scheduling PDSCH is indicated by two TCI states, then the TCI states or QCL assumptions for PDSCH may be the same as the first TCI states and first QCL assumptions applied for CORESET. Setting SFN method A may also mean setting sfnSchemePdcch to which 'sfnSchemeA' is set.

[0270] If a unified TCI state is not set, and the time offset is less than the threshold, If at least one set TCI state includes a qcl-Type with typeD set, then the DMRS port of the PDSCH may have RS and QCL with respect to a certain QCL parameter. The data may be used for PDCCH QCL indication in a certain CORESET. A certain CORESET is the latest This could also be a CORESET associated with the search area with the lowest CORESET ID (controlResourceSetId) among the CORESETs monitored by terminal device 1 in a lot.

[0271] If a unified TCI state is set, and the time offset is less than the threshold, If at least one TCI state to be set includes a qcl-Type to which typeD is set, and If the indicated TCI state is related to the PCI (Physical Cell ID) of the serving cell, the indicated TCI state may be applied to PDSCH reception. When a unified TCI state is set, and at If the inter-offset is less than the threshold, and at least one set TCI state includes a qcl-Type where typeD is set, and the indicated TCI state is associated with a PCI (Physical Cell ID) other than the serving cell, the DMRS port of the PDSCH in the serving cell is connected to the reference signal and QCL associated with the QCL parameter of the CORESET associated with the lowest CORESET ID. Alternatively, the setting of a unified TCI state may be achieved by setting the upper-level parameter dl-OrJointTCI-StateList.

[0272] If a first terminal capability is indicated to terminal device 1, terminal device 1 may determine a spatial domain filter. The spatial domain filter may be used while performing applicable channel access procedures before UL transmission on the channel. If an SRI corresponding to UL transmission is indicated In this case, terminal device 1 may use the same spatial domain filter as the spatial domain filter associated with the indicated SRI. Terminal device 1 may use the same spatial domain filter as the spatial domain filter used to receive the DL reference signal associated with the indicated TCI state. For example, when TCI-State or TCI-UL-State is set, terminal device 1 may use the same spatial domain filter as the spatial domain filter associated with the indicated TCI state. The same spatial domain filter used to receive the DL reference signal may be used. The first terminal capability may be beamCorrespondenceWithoutUL-BeamSweeping, which is set to '1'.

[0273] For Periodic CSI-RS resources, the TCI state is SS / PBCH block and It may be indicated that the type C is QCL. The SS / PBCH block may have a different PCI than the serving cell PCI. The periodic CSI-RS resource is a CSI-RS resource in the NZP CSI-RS resource set (NZP-CSI-RS-ResourceSet) for the Tracking Reference Signal (TRS). It may also be a non-zero power (NZP) set. The CSI-RS resource set for TRS may be a CSI-RS resource set in which the upper-layer parameter trs-Info is set.

[0274] When a unified TCI state is set for periodic CSI-RS and semi-persistent CSI-RS resources, terminal device 1 assumes that the indicated TCI state will not be applied. You may do so.

[0275] For aperiodic CSI-RS resources, the TCI state is a periodic CSI-RS resource. You may indicate that it is QCL with respect to - and type A. Non-periodic CSI-RS resources may be CSI-RS resources in the NZP CSI-RS resource set for TRS. Periodic CSI-RS resources may be CSI-RS resources in the NZP CSI-RS resource set for TRS.

[0276] For the first CSI-RS resource, the TCI status may indicate that it is QCL with respect to the second CSI-RS resource and type A. For the first CSI-RS resource, the TCI status may indicate that it is QCL with respect to the third CSI-RS resource and type B. The first CSI-RS resource may be a CSI-RS resource in the NZP CSI-RS resource set for TRS. The first CSI-RS resource does not have to be a CSI-RS resource in the NZP CSI-RS resource set for repetition. The second CSI-RS resource is the NZP CSI-RS resource set for TRS. A third CSI-RS resource may be one to which Type D can be applied. If not, the CSI-RS resource in the NZP CSI-RS resource set for TRS is This is also acceptable. The CSI-RS resource set for repetition may be a CSI-RS resource set with the upper-level parameter `repetition`.

[0277] For the fourth CSI-RS resource, the TCI status may indicate that it is QCL with respect to the second CSI-RS resource and type A. For the fourth CSI-RS resource, the TCI status is SS / PBCH. You may also indicate that it is QCL with respect to blocks and type C. The fourth CSI-RS resource is, This could also be a CSI-RS resource in the NZP CSI-RS resource set for repetition.

[0278] If a unified TCI state is not set, the TCI state for DMRS in PDCCH is the CSI-RS resource. It may also be indicated that it is a QCL with respect to type A. The CSI-RS resource may also be a CSI-RS resource in the NZP CSI-RS resource set.

[0279] When SFN method A is set for PDCCH and CORESET is activated in two TCI states, the DMRS port of PDCCH in CORESET may be DL RS (downlink reference signal) and QCL in the two TCI states. When SFN method B is set for PDCCH and two TCI states When CORESET is activated in this state, the DMRS port of PDCCH in CORESET is in two TCI states The DL RS and QCL may be, and the second TCI state does not have to include the QCL parameters {Doppler shift, Doppler spread}. Setting SFN method A for PDCCH may mean setting sfnSchemePdcch with 'sfnSchemeA' set. Setting SFN method B for PDCCH may mean setting sfnSchemePdcch with 'sfnSchemeB' set It is also acceptable for this to be set.

[0280] A Coherent Joint Transmission (CJT) may be configured for PDSCH. Configuring CJT may also involve configuring the upper-level parameter cjtSchemePDSCH. Configuring CJT method A may involve configuring the upper-level parameter cjtSchemeA. Configuring CJT method B may involve configuring the upper-level parameter cjtSchemeB. When CJT method A is configured for PDSCH, the DMRS port of PDSCH may be QCL with respect to two indicated TCI state reference signals and QCL type A. When CJT method B is configured for PDSCH, the DMRS port of PDSCH may be QCL with respect to two indicated TCI state reference signals and QCL type A, excluding the QCL parameters {Doppler shift, Doppler spread}.

[0281] If a unified TCI state is not set, the TCI state for DMRS in PDSCH is the CSI-RS resource. It may also be indicated that it is a QCL with respect to Type A. The CSI-RS resource may also be a CSI-RS resource in the NZP (Non-zero power) CSI-RS resource set.

[0282] When a unified TCI state is set, for DMRS of PDCCH, the TCI state is CSI-RS resource and It may be indicated that it is QCL with respect to Type A. When a unified TCI status is set, for DMRS of PDSCH, the TCI status indicates that it is QCL with respect to CSI-RS resources and Type A. That's fine.

[0283] If SFN method A is set for PDSCH and two TCI states are indicated, the DMRS port of PDSCH may be DL-RS and QCL for the two TCI states. SFN method B for PDSCH If this is set and two TCI states are indicated, the DMRS ports of the PDSCH may be DL-RS and QCL of the two TCI states. If SFN method B is set for the PDSCH and two TCI states are indicated, the DMRS ports of the PDSCH may be DL-RS and QCL of the two TCI states. It is also possible that the second TCI state does not include the QCL parameters {Doppler shift, Doppler spread}. The two TCI states may be indicated by one code point in the DCI field 'Transmission Configuration Indication' in the DCI that schedules the PDSCH. Setting up SFN method A for the PDSCH means that 'sfnSchemeA' is set The sfnSchemePdsch that is set may be configured. For PDSCH, the SFN method B is Being set may also mean setting sfnSchemePdsch, which has 'sfnSchemeB' set to it.

[0284] If a unified TCI state is set, and multi-DCI mode is set, and one The indicated TCI state is a DCI format related to the value of one CORESET pool index. When indicated by the TCI field (DCI field 'Transmission Configuration Indication') in 1_1 / 1_2, one indicated TCI state may correspond to one CORESET pool index value. A unified TCI state may be set by setting dl-OrJointTCI-StateList or TCI-UL-State. When multi-DCI mode is set This may involve setting the upper-layer parameter PDCCH-Config, which includes two different CORESET pool index values. This may be set in the ControlResourceSet.

[0285] If a unified TCI state is set, and terminal device 1 has two indicated TCI-States, and the terminal capability of the default beam is not reported, and the time offset is less than the threshold, then the first indicated TCI-State may be applied to PDSCH reception. The terminal capability of the default beam has two indicated states to buffer the received signal before the threshold. The ability to use the TCI state may also be the ability in FR2 (Frequency Range 2). For example, FR2 may be a frequency range from 24250MHz to 52600MHz. The time offset may be the offset between the scheduled DCI format 1_0 / 1_1 / 1_2 reception and the scheduled PDSCH reception. The time offset may be the offset between the reception of the DCI format 1_0 / 1_1 / 1_2 that is activated and the reception of the PDSCH that is activated. The threshold may be timeDurationForQCL, or a value smaller than timeDurationForQCL.

[0286] If a unified TCI state is set, and multi-DCI mode is set, and the terminal capability of the default beam is not reported, and the first time offset is less than the threshold, then the “indicated TCI state” corresponding to CORESET pool index 0 may be applied to PDSCH reception. If a unified TCI state is set, and multi-DCI mode is set, and the terminal capability of the default beam is not reported, then it is not expected that the second time offset will be less than the threshold. The first time offset is CORESET The second time offset is the offset between the reception of the DCI format in CORESET associated with pool index 0 and the reception of the PDSCH. That's good too.

The (k+1)th entry of the CSI-IM resource in the CSI-IM resource set for interference measurement may correspond to the SSBRI value k. The NZP CSI-RS resource in the NZP CSI-RS resource set for interference measurement The (k+1)th entry in the source may correspond to the SSBRI value k.

[0358] If the reporting volume setting is set to cri-RSRP, cri-SINR, none, cri-RSRP-Index, or cri-SINR-Index, and one CSI reporting setting is linked to one aperiodic CSI resource setting, then 16 will be set in one CSI-RS resource set in one CSI resource setting. It is not necessary to expect that the CSI-RS resources will exceed the specified limits.

[0359] In the L1-RSRP calculation, CSI-RS resources, SS / PBCH block resources, or both CSI-RS and SS / PBCH block resources may be configured. In the L1-RSRP calculation, up to 16 CSI-RS resource sets may be configured, and up to 64 CSI-RS resources may be configured within each CSI-RS resource set.

[0360] In L1-RSRP calculations, one CRI or SSBRI is reported for each CSI report setting. In this case (for example, when nrofReportedRS is 1), the reported L1-RSRP value is defined as 7 bits. It is also possible that the range of the L1-RSRP value is -140 dBm to -44 dBm. The L1-RSRP value may be given in 1 dB intervals.

[0361] In L1-RSRP calculations, if multiple CRIs or SSBRIs are reported for each CSI report setting (for example, if nrofReportedRS is 2 or more), the first reported L1-RSRP value will be 7. The first value may be defined in bits, and the second value of the reported L1-RSRP may be defined in 4 bits. The range of the first value may be from -140 dBm to -44 dBm. The first value may be given in 1 dB intervals. The second value may be calculated as the difference between the first values. The second value may be given in 2 dB intervals. It may be given as a distance.

[0362] When group-based reporting is configured, terminal device 1 may indicate one CSI-RS resource set. One CSI-RS resource set may be associated with the maximum value of L1-RSRP. The CRI or SSBRI of the CSI-RS resource set may be placed at the beginning.

[0363] Terminal device 1 may calculate L1-RSRP based on the NZP CSI-RS or SS / PBCH block. For example, if no time limit is set, terminal device 1 may perform channel measurements based on the SS / PBCH block or NZP CSI-RS for L1-RSRP calculation. If limits are set, terminal device 1 may perform channel measurements based on the latest opportunity of the SS / PBCH block or NZP CSI-RS for L1-RSRP calculation.

[0364] In L1-SINR calculations, either or both of the NZP CSI-RS resource and / or the SS / PBCH block resource may be configured for channel measurement. In L1-SINR calculations, either the NZP CSI-RS resource or the CSI-IM resource may be configured for interference measurement.

[0365] L1-SINR calculation and channel measurement may have a CSI resource configuration with up to 16 CSI-RS resource sets, and a total of 64 CSI-RS resources or SS / PBCH block resources. The source may be set.

[0366] In L1-SINR calculations, one CRI or SSBRI is reported for each CSI report setting. In this case (for example, when nrofReportedRS is 1), the reported L1-SINR value is defined as 7 bits. It is also possible that the range of the L1-SINR value is -23 to 40 dB. The L1-SINR value may be given in 0.5 dB intervals.

[0367] In L1-SINR calculations, if multiple CRIs or SSBRIs are reported for each CSI report setting (for example, if nrofReportedRS is 2 or more), the first reported L1-SINR value will be 7. The first value may be defined in 1dB increments, and the second value of the reported L1-SINR may be defined in 4 bits. The range of the first value may be from -23dB to 40dB. The first value may be given in 0.5dB increments. The second value may be calculated as the difference between the first and second values. The second value may be given in 1dB increments. It may be given as follows.

[0368] Aperiodic CSI reports may also correspond to aperiodic CSI-RS. Related to aperiodic, periodic, or semi-persistent CSI resource settings. In the CSI-RS resource set, the trigger state for aperiodic CSI reporting settings is determined by a higher-level parameter (e.g., CSI-AperiodicTriggerStateList). The trigger state may be set for CSI resource settings for either channel measurement or interference measurement, or both.

[0369] In a non-periodic CSI reporting configuration, one set of trigger states may be configured by the upper layer. The trigger state may be associated with any one downlink BWP.

[0370] Terminal device 1 may receive a DCI with a CSI request field. Two or more DCIs with CSI request fields are received in one slot in one cell. It's not necessary to expect to be trusted.

[0371] In multiple aperiodic CSI-RS resource sets with the same trigger offset in the same trigger state, different TCI states are set for the same aperiodic CSI-RS resource ID. It is not necessary to expect that.

[0372] It is not necessary to expect that two or more requests for aperiodic CSI reports will be received in a single slot within a single cell.

[0373] The trigger state may be initiated by the CSI request field in DCI. If all information bits in the request field are set to zero, the CSI will reject the request. It doesn't have to be done.

[0374] The number of trigger states is 2^N TS If it is -1 or greater, terminal device 1 will display a subset indication. It may be received. The subselection indication can be up to 2^N in the code points of the CSI request field. TS It may be used to map the trigger state of -1. TS CSI Request Stoffield's bit count may also be acceptable.

[0375] When terminal device 1 transmits the first PUCCH in slot n, the mapping between the CSI request field and the trigger state may be applied after slot n+N. The first PUCCH may be a PUCCH accompanied by HARQ-ACK information corresponding to a PDSCH that transmits a subsettion indication. .

[0376] The CSI request field may indicate a single trigger state. For example, the number of trigger states could be 2^N. TS If it is less than -1, the CSI request field indicates one trigger state. That's fine.

[0377] In one CSI-RS resource set associated with each trigger state (CSI triggering state) For each non-periodic CSI-RS resource, a first QCL setting and a first QCL type may be specified.

[0378] If a list of trigger states for aperiodic CSI (e.g., CSI-AperiodicTriggerStateList) is configured, and one CSI resource configuration linked to one CSI report configuration has multiple aperiodic CSI-RS resource sets, then one aperiodic CSI-RS resource set A single trigger state may be associated with a single CSI resource configuration. In a single trigger state within a single CSI resource configuration, a single CSI-IM / NZP CSI-RS resource set may be selected.

[0379] When aperiodic CSI reports and aperiodic CSI-RS are used, one trigger offset (or CSI-RS offset) is used in one CSI-RS resource set (NZP CSI-RS resource set, CMI-IM resource set, or SS / PBCH block resource set). A good value may be set. The trigger offset may be set by a higher layer parameter (e.g., aperiodicTriggeringOffset). The trigger offset may include a number of slots from 0 to N. N may be based on the subcarrier interval of CSI-RS. CSI-IM trigger The GA offset may follow the trigger offset of the NZP CSI-RS for channel measurement.

[0380] Terminal device 1 may receive CSI-RS. Non-periodic CSI-RS may be transmitted in slot n+X. Slot n may be a slot containing a DCI that triggers the CSI-RS. This may also be a trigger offset.

[0381] A non-periodic CSI-RS does not have to be transmitted before the first OFDM symbol. The first OFDM symbol may be a symbol that transmits a DCI that triggers the CSI-RS transmission. If scheduling offset limits apply and the trigger offset is less than or equal to the minimum scheduling offset limit, it is not expected that the CSI-RS will be triggered by the trigger condition indicated by the CSI request field in the DCI. The CSI-RS transmission may be triggered by the trigger condition indicated by the DCI request field in the DCI.

[0382] When interference measurements are performed in a non-periodic NZP CSI-RS, the trigger offset for the NZP CSI-RS used for interference measurements may be the same as the trigger offset for the NZP CSI-RS used for channel measurements.

[0383] It is not expected that multiple CSI reports triggered by different DCIs will be sent on a single carrier for the same OFDM symbol.

[0384] The scheduling offset between the last symbol of the PDCCH that transmits the DCI triggering the aperiodic CSI-RS resource and the first symbol of the aperiodic CSI-RS resource may be determined. If two PDCCH candidates exist, the later-terminating PDCCH candidate may be used to determine the scheduling offset. The last symbol of the earlier-terminating PDCCH candidate may be the same as or later than the first symbol of the aperiodic CSI-RS resource.

[0385] Semi-persistent CSI may also support semi-persistent CSI-RS. In PUSCH's semi-persistent CSI reporting, a set of trigger states is a higher-level parameter (e.g., For example, it may be set by SemiPersistentOnPUSCH-TriggerStateList. The CSI request field in DCI, which is scrambled by SP-CSI-RNTI, is one trigger state The state may be activated. Terminal device 1 does not need to expect to receive a first DCI that activates the first semi-persistent CSI report. The first semi-persistent CSI report may have the same CSI report setting ID as the second semi-persistent CSI report. The report may be activated by the second DCI. The first and second DCIs may be scrambled by SP-CSI-RNTI. Terminal device 1 activates the second DCI before the first DCI. You may receive it.

[0386] In semi-persistent CSI reporting in PUCCH, the PUCCH resource used to send the CSI report may be configured by a higher-level parameter (reportConfigType). The semi-persistent CSI report in this system may be activated by the activation command. The command may select one semi-persistent CSI report setting. Terminal device 1 activates The terminal device 1 may receive a PDSCH that transmits a mand. In slot n, terminal device 1 may transmit a PUCCH with HARQ-ACK information corresponding to the PDSCH. The selected semi-persistent CSI report settings may be applied to slots n+N and beyond.

[0387] If a semi-persistent CSI resource setting is configured (for example, if resourceType is set to semiPersistent), and terminal device 1 receives an activation command, CSI-RS / CSI-IM transmission may be applied from slot n+N for the CSI-RS resource set for channel measurement and the CSI-IM / NZP CSI-RS resource set for interference measurement. Terminal device 1 will then apply the CSI-RS / CSI-IM transmission from slot n+N. Alternatively, a PUCCH with HARQ-ACK information may be sent to the PDSCH that transmits the command.

[0388] Terminal device 1 may receive a deactivation command. If a semi-persistent CSI resource setting is configured and terminal device 1 receives a deactivation command, the termination of CSI-RS / CSI-IM transmission may be applied from slot n+N. Terminal device 1 deactivates slot n. You may send a PUCCH with HARQ-ACK information to a PDSCH that transmits a command.

[0389] A trigger state (e.g., SP-CSI triggering state) may be mapped to a code point in the CSI request field in the DCI. Terminal device 1 verifies the PDCCH in the DCI for activation or deactivation (release) of the semi-persistent CSI. This is also possible. For example, if the CRC in DCI format is scrambled with SP-CSI-RNTI, Terminal device 1 may verify PDCCH. For example, special functions in DCI format Based on the value set in the field, terminal device 1 activates or deactivates the semi-permanent CSI. It's okay to change it.

[0390] Terminal device 1 may activate or deactivate the CSI report settings indicated by the DCI request field in DCI.

[0391] If a CSI resource setting (e.g., CSI-RS / CSI-IM resource setting, or ZP (Zero Power) CSI-RS resource set setting) is activated and the corresponding downlink BWP is active, the CSI resource setting may be considered. If a CSI resource setting (e.g., CSI-RS / CSI-IM resource setting, or ZP (Zero Power) CSI-RS resource set setting) is activated and the corresponding downlink BWP is inactive, the CSI resource setting may be suspended.

[0392] Terminal device 1 may report CQI. Terminal device 1 calculates one CQI index. It is also possible. The modulation scheme, encoding, and transport block of the PDSCH The block size may correspond to one CQI index. Terminal device 1 is the target The PDSCH transport block may be received in such a way that the error probability does not exceed the target error. The probability may also be the error probability of the transport block. The target error probability is 0.1 Alternatively, it may be 0.00001.

[0393] Terminal device 1 may report PMI. Terminal device 1 will report the number of antenna ports (CSI port The PMI may be determined based on the number of ports (number of CSI-RS ports) and the number of layers. The number of layers ν may be related to the RI. The PMI value corresponding to type 1 is i1∈i 1,1 i 1,2 i1,3 i 1,4 And it may consist of part or all of i2. The PMI corresponding to type 1 may be the PMI when typeI-SinglePanel or typeI-MultiPanel is set in the codebook settings. The value of the PMI corresponding to type 2 is i1∈i 1,1 i 1,2 i 1,3,1 i 1,3,2 i 1,4,1 i 1,4,2 And may consist of part or all of i2. A PMI corresponding to type 2 is a PMI when any of typeII, typeII-r16, typeII-PortSelection-r16, typeII-r17, typeII-PortSelection-r17, typeII-CJT-r18, typeII-CJT-PortSelection-r18, typeII-Doppler-r18, and typeII-Doppler-PortSelection-r18 is set in the codebook settings. good.

[0394] If an extended CSI port is not configured, the number of CSI ports may be 4, 8, 12, 16, 24, or 32. If an extended CSI port is configured, the number of CSI ports may be 48, 64, 96, or 128. The absence of an extended CSI port means that the number of CSI ports set to one of 4, 8, 12, 16, 24, or 32 is... It is also possible that the expansion CSI ports are configured by setting the number of CSI ports to 48, 64, 96, and 128.

[0395] One or more NZP CSI-RS resource sets may be configured by a CSI resource configuration (CSI-ResourceConfig).

The third upper-layer parameter may determine the frequency density of each CSI port (antenna port, CSI-RS port) per PRB. The third upper-layer parameter may be 0.5even, 0.5odd, 1, or 3. It may be set.

[0401] One or more parameters P include a fourth upper-level parameter that determines the CDM type. Alternatively, the fourth upper-level parameter may be set in the first upper-level parameter. The fourth upper-level parameter may determine the value and pattern of the CDM.

[0402] One or more parameters P may include parameters that determine the Energy per Resource element (EPRE) ratio for PDSCH and NZP CSI-RS.

[0405] One or more parameters P may include a BWP ID. The BWP ID is in the CSI resource configuration. It may be set in the location. The BWP ID may determine the BWP where the CSI-RS is located.

[0406] One or more parameters P may include repeat settings. Repeat settings may be set in the CSI-RS resource set. In an NZP CSI-RS resource set for repeating (an NZP CSI-RS resource set in which repeat settings are set), it may be assumed that the CSI-RS resources in the NZP CSI-RS resource set are transmitted with the same downlink spatial domain transmit filter. Repeat settings may be set if the reporting amount setting is set to cri-RSRP, cri-SINR, cri-RSRP-Index, cri-SINR-Index, or none.

[0407] One or more parameters P may include QCL information for periodic CSI-RS. The QCL information may include a reference to the TCI state. The TCI state may indicate the QCL source RS and the QCL type.

[0408] One or more parameters P may include a TRS (Tracking Reference Signal) setting. The TRS setting may be set in the CSI-RS resource set. In the NZP CSI-RS resource set for TRS (the NZP CSI-RS resource set in which the TRS setting is set), The antenna port for the NZP CSI-RS resource in a set may be the same.

[0409] For CSI-RS resources for all channel measurements in one CSI-RS resource set The same frequency density and the same number of antenna ports may be set. One CSI-RS resource center For all CSI-RS resources in the set, the same starting RB (Resource Block) location, the same number of RBs, and the same CDM type may be configured.

[0410] The bandwidth and starting CRB (Common resource block) index of a CSI-RS resource may be determined by the starting RB location and number of RBs. The starting RB location and number of RBs may be determined by higher-level parameters (e.g., startingRB and nrofRBs). The starting RB location and number of RBs may be set as integer multiples of 4 RBs. The reference location for the starting RB location may be CRB0. The bandwidth (number of RBs) of a CSI-RS resource may be 24 RBs or more, and greater than or equal to the BWP size.

[0411] One or more CSI-IM resource sets may be configured. Each CSI-IM resource set is It may consist of one or more CSI-IM resources. One or more parameters Q may be set for the CSI-IM resources.

[0412] One or more parameters Q may include the CSI-IM resource ID. Meter Q is the subcarrier position k within one slot of the CSI-IM resource. CSI-IM The decision Parameters may be included. One or more parameters Q are in one slot of the CSI-IM resource. OFDM symbol position l CSI-IM The parameters may include those that determine the period and slot offset for periodic / semi-permanent CSI-IMs. The parameters may include those that determine the bandwidth of the CSI-IM.

[0413] A CSI-IM resource may consist of four REs. For example, in Pattern 1, the CSI-IM resource is (k CSI-IM , l CSI-IM ), (k CSI-IM , l CSI-IM (+1), (k CSI-IM +1, l CSI-IM ), and (k CSI-IM +1, l CSI-IM It may consist of REs corresponding to +1). For example, in pattern 2, the CSI-IM resource is (k CSI-IM , l CSI-IM ), (k CSI-IM +1, l CSI-IM ), (k CSI-IM +2, l CSI-IM ), and, (k CSI-IM +2, l CSI-IM It may also consist of REs corresponding to +1).

The CSI reference resource in the frequency domain may be a Physical Resource Block (PRB) corresponding to the bandwidth in which the CSI is calculated. The CSI reference resource in the time domain may be a single slot. This single slot may be N points earlier than the slot in which the CSI is reported. The N slot may be determined based on the delay time.

[0415] Terminal device 1 may calculate and report the CQI (CQI Index) based on the CSI reference resource. Terminal device 1 may perform one or more operations to calculate the CQI. It is also possible to consider the situation.

[0416] One of the situations in which two OFDM symbols are occupied by control signals is It may be either. One of the situations in which the number of PDSCH and DMRS is 12 symbols. It may be either. One or more situations is that the same subcarrier interval as PDSCH reception. It may be the case that: One or more situations may be that the CSI reference resource uses the same CP length and subcarrier spacing as the PDSCH. One or more situations may be that there is no RE used for PBCH, PSS, or SSS. One of the situations may be that the Redundancy Version is 0. One possibility is that there are no REs allocated for NZP CSI-RS and ZP CSI-RS. One of the situations in which the maximum number of Front-loaded DMRS symbols set is used is It may also be possible that one of the following situations is that an Additional DMRS system is set. The number of 'mbol' may be used. In one or more situations, the OFDM symbol for PDSCH may not include DMRS. In one or more situations, two PRBs This may also involve bundling.

[0417] One of the situations is that for the ν layer signal in PDSCH, the PMI corresponding to P The recorder may be multiplied. The number of layers may be up to 8.

[0418] Terminal device 1 may report CSI using PUSCH. Depending on the decoding of the DCI format that triggers the trigger state, terminal device 1 reports aperiodic CSI using PUSCH. You may do so.

[0419] The DCI format may schedule two pushes. In this case, the aperiodic CSI report may be executed in the second push. The DCI format may schedule three or more pushes. In this case, the aperiodic CSI report may be executed in the second to last push. This may be performed in the PUSCH command.

[0420] Non-periodic CSI reports in PUSCH may correspond to full-band and sub-band frequency granularity.

[0421] Terminal device 1, in response to decoding the DCI format that activates the trigger state, sends a message to PUSCH. You may report semi-permanent CSIs in this format. The field may indicate a trigger state for activation or deactivation.

[0422] Non-periodic CSI reports in PUSCH are multiplexed with uplink data in PUSCH. It is also acceptable. The semi-permanent CSI report in PUSCH is based on the uplink data in PUSCH and You don't need to expect it to be duplicated.

[0423] When PMI is reported (or feedback) in PUSCH, the CSI report may consist of Part 1 and Part 2. Part 1 is a fixed number of bits to indicate the number of information bits in Part 2. It may also be a payload of .Part 1 may be added or sent before Part 2.

In slot n, a PUCCH may be sent with HARQ-ACK information corresponding to a PDSCH that transmits an activation command. The activation command may include one or more CSI report settings.

[0427] Terminal device 1 may report CSI. CSI may include some or all of PMI, RI, LI, CQI, CRI, SSBRI, RSRP, SINR, CapabilityIndex, and TDCP. CSI may also be a collective term for PMI, RI, LI, CQI, and CRI.

[0428] The bit size of the PMI (Precoding Matrix Indicator) may be determined based at least on the number of antenna ports and the number of layers.

[0429] The bit size of the RI (Rank Indicator) may be determined based on at least the number of antenna ports and the number of ranks to be set. The bit size of the LI (Layer Indicator) may be determined based on the number of ranks. The bit size of the CRI (CSI-RS resource indicator) may be determined based on at least the number of CSI-RS resources in the CSI-RS resource set.

[0430] DCI formats 1_0 / 1_1 / 1_2 may be used for PDSCH scheduling. The Bandwidth Part Indicator (BWP) field may be included in either or both of DCI Format 1_1 and DCI Format 1_2. The number of information bits constituting the BWP field may be determined based on the number of DL BWPs. The TPC command (TPC command for scheduled PUCCH) field may be included in either or both of DCI Format 1_1 and DCI Format 1_2. Second TPC command for scheduled The PUCCH) field is either DCI Format 1_1 or DCI Format 1_2 or It may be included in both. For example, if the upper-level parameter SecondTPCFieldDCI is set. The second TPC command (Second TPC command for scheduled PUCCH) field may be included in DCI format 1_1.

[0431] The TCI (Transmission configuration indication) field may be included in either or both of DCI format 1_1 and DCI format 1_2. For example, if higher-level parameters are set, the TCI (Transmission configuration indication) field may be DCI It may be included in either or both of Format 1_1 and DCI Format 1_2. Example For example, if the upper-level parameter tci-PresentInDCI is set, the TCI (Transmission configuration indication) field may be included in either or both of DCI format 1_1 and DCI format 1_2. One or two TCI states may be indicated by the DCI format. One or more (e.g., two) TCI states are indicated in the TCI format. This may be indicated by a field.

[0432] The DCI format 0_0 / 0_1 / 0_2 may be used for scheduling in PUSCH. The Bandwidth Part Indicator (BWP) field may be included in part or all of DCI Format 0_1 ​​and DCI Format 0_2. The number of information bits constituting the BWP field may be determined based on the number of UL BWPs. The TPC command (TPC command for scheduled PUSCH) field may be included in either or both of DCI Format 0_1 ​​and DCI Format 0_2. Second TPC command for scheduled The PUSCH) field is either DCI format 0_1 ​​or DCI format 0_2 or It may be included in both. For example, if the upper-level parameter SecondTPCFieldDCI is set. The second TPC command (Second TPC command for scheduled PUSCH) field may be included in DCI format 1_1.

[0433] CSI-RS (Channel state information reference signal) is ZP (zero power) CSI-RS or Alternatively, it could be NZP (Non-zero-power) CSI-RS.

[0434] The CSI-RS sequence may be r(m). r(m) may be determined by a pseudorandom sequence (e.g., a gold code). The pseudorandom sequence is an OFDM symbol in one slot. DEX, slot index n within one wireless frame μ s,f , and may be initialized based on a scrambled ID.

[0435] In each CSI-RS, the CSI-RS sequence r(m) is a Resource element (RE) (k,l) p,μ It may be mapped to β. For example, the CSI-RS sequence r(m) is β CSIRS *w f (k')*w t (l')*r(m) is a resource element (RE) (k,l) p,μ It may be mapped to: k is the subcarrier position, l is the OFDM symbol position, p is the antenna port (CSI port), and μ is the subcarrier spacing setting. β CSIRS is the scaling factor, w f (k') is FD-OCC (Frequency domain orthogonal cover code), w t (l') may also be TD-OCC (Time domain orthogonal cover code).

[0436] In ZP CSI-RS, β CSIRS It may be 0. In NZP CSI-RS, β CSIRS is greater than 0 β is acceptable. CSIRS This is determined based on higher-level parameters (e.g., powerControlOffsetSS). It may also be used as a fixed term.

[0437] In r(m), m is floor(n*α)+k'+floor((k bar *ρ) / N RB SC ) is also acceptable. * may also be multiplication.

[0438] ρ may also be the frequency density. When the number of antenna ports is 1, α is ρ. This is also acceptable. If the number of antenna ports is 2 or more, α may be 2ρ. In this case, each antenna port may be mapped every 1RB. If ρ is 0.5, each Antenna ports may be mapped. If ρ is an even number of 0.5, each antenna port may be mapped to an even-numbered RB every 2RBs. If ρ is an odd number of 0.5, each antenna port may be mapped to an odd-numbered RB every 2RBs.

[0439] The subcarrier position k is determined by the PRB position n and the subcarrier position setting k. bar This may be determined by the FD-OCC (Frequency Domain-Orthogonal Cover Code) index k'.

[0440] Subcarrier position k=0 may correspond to subcarrier 0 in CRB0.

[0441] The PRB position n may be a value between 0 and N-1. N may be the bandwidth of the CSI-RS resource (e.g., the number of RBs: nrofRBs).

[0442] Subcarrier position setting kbar This may determine the subcarrier position within a single slot. Subcarrier position setting k bar This is related to the number of antenna ports, frequency density, and CDM type. It may be determined based on the following: Subcarrier position setting k bar is a subcarrier within one RB Position A is also acceptable. bar is, k i It is also acceptable. i-1 f(i) may also be f(i). f(i) may be the bit number of the i-th bit in the bitmap that is set to 1. The bitmap is provided by higher-layer parameters (e.g., frequencyDomainAllocation). This may be done. The size of the bitmap may be determined based on at least the number of antenna ports. f(i) may be repeated for every ceil(1 / ρ) RBs.

[0443] The FD-OCC index k' may be determined by the CDM type. If the CDM type is set to "No CDM", k' may be 0. If the CDM type is set to a CDM of length 2 in the frequency domain (FD), k' may be 0 or 1.

[0444] OFDM symbol position l is OFDM symbol position setting l bar and TD-OCC (Time domain-Orthogonal The cover code may be determined by index l' and other factors.

[0445] OFDM Symbol Positioning bar This may determine the symbol position within a single slot. OFDM Symbol Position Setting l bar This may be determined based on the number of antenna ports, frequency density, and CDM type. barl0 and l1 may be one or both. l0 may be determined by a first upper-layer parameter (e.g., firstOFDMSymbolInTimeDomain). l1 may be determined by a second upper-layer parameter (e.g., firstOFDMSymbolInTimeDomain2). l0 may be an integer value from 0 to 13. l1 may be an integer value from 2 to 12.

[0446] The TD-OCC index l' may be determined by the CDM type. If the CDM type is set to No CDM, l' may be 0. If the CDM type is set to a CDM of length 2 in the Time Domain (TD), l' may be 0 or 1. If a CDM of length 4 is set, ’ This can be 0, 1, 2, or 3.

[0447] The antenna port p may be 3000 + s + j * L. The sequence index s may be an integer value from 0 to L-1. The CDM group size L may be any of 1, 2, 4, and 8. The CDM group size L may be determined based on the CDM type. For example, the CDM group size L may be the product of the length of the TD-OCC and the length of the FD-OCC. The CDM group index j may be an integer value from 0 to N / L-1. N may be the number of antenna ports (number of CSI-RS ports).

[0448] If the FD-OCC index k' is 0, w f (k') may be 0. FD-OCC index k If ' is 0 and 1, [w f (0) w f (1) may be the vectors [+1 +1] and [+1 -1]. If the TD-OCC index l' is 0, w t (l') may be 0. TD-OCC index l' is 0 And in the case of 1, [w t (0) w t (1) may be the vectors [+1 +1] and [+1 -1]. If the TD-OCC index l' is 0, 1, 2, and 3, then [w t (0) w t (1) w t (2) w t (3) is the vector [+1 +1 + 1 +1], [+1 -1 +1 -1], [+1 +1 -1 -1], and [+1 -1 -1 +1]. The series index s is first indexed with FD-OCC, and then indexed with TD-OCC. It is acceptable to attach them together. For example, a CDM type can be fitted with FD-OCC of length 2 and TD-OCC of length 4. When this is done, the series index s=0 is [w f (0) w f (1)]=[+1 +1]and[w t (0) w t (1) w t (2) w t (3) = [+1 +1 + 1 +1], and the sequence index s=1 is [w f (0) w f (1)] = [+1 -1] and [w t (0) w t (1) w t (2) w t (3) = [+1 +1 + 1 +1], and the sequence index s=2 is [w f (0) w f (1)]=[+1 +1] and [w t (0) w t (1) w t (2) w t (3) = [+1 -1 + 1 -1], and the sequence index s=3 is [w f (0) w f (1)]=[+1 -1]and[w t (0) w t (1) w t (2) w t(3) = [+1 -1 + 1 -1], and the sequence index s=4 is [w f (0) w f (1)]=[+1 +1]and[w t (0) w t (1) w t (2) w t (3)] ​​= [+1 +1 -1 -1] The series index s=5 is [w f (0) w f (1)]=[+1 -1]and[w t (0) w t (1) w t (2) w t (3) = [+1 +1 -1 -1], and the sequence index s=6 is [w f (0) w f (1)]=[+1 +1]and[w t (0) w t (1) w t (2) w t (3) = [+1 -1 -1 +1], and the sequence index s=7 is [w f (0) w f (1)]=[+1 -1]and[w t (0) w t (1) w t (2) w t (3) = [+1 -1 -1 +1] is also acceptable.

[0449] CDM groups are indexed first by frequency resources, followed by time resources. Indexing may be performed as follows. For example, if the number of antenna ports is 32 and the CDM type is set to FD-OCC (fd-CDM2) with a length of 2, the CDM group index j is The time-frequency resources may be indexed in the following order: (k0,l0), (k1,l0), (k2,l0), (k3,l0), (k0,l0+1), (k1,l0+1), (k2,l0+1), (k3,l0+1), (k0,l1), (k1,l1), (k2,l1), (k3,l1), (k0,l1+1), (k1,l1+1), (k2,l1+1), and (k0,l1+1).

[0450] Terminal device 1 does not need to expect to receive CSI-RS and DMRS in the same RE. Antenna ports within a single CSI-RS resource may be QCL relative to each other with respect to Type A. Device 1 may expect that the antenna ports within one CSI-RS resource have an average gain.

[0451] The settings for scheduling requests may also be configured by higher-level parameters (e.g., SchedulingRequestResourceConfig). The setting may determine one PUCCH resource. One PUCCH resource is a PUCCH four It may support MAT0 or PUCCH format 1. For scheduling requests The settings may determine the period T and offset ΔT for PUCCH, which transmits scheduling requests. The period may be represented by OFDM symbols or slots. The terminal device 1 may determine the opportunity to send a scheduling request in PUCCH. mod(n f *N frame,μ slot +n μ s,f If -ΔT, T) is 0, the transmission opportunity is slot number n μ s,f It may also be a corresponding slot. The settings for the scheduling request may determine the transmission period. The transmission period may be the number of OFDM symbols.

[0452] The uplink grant configured for PUSCH transmission may be set by higher-tier parameters (e.g., configuredGrantConfig). PUSCH resources (resource allocation) This may be set by upper layer parameters. The upper layer parameters are one uplink It may also be related to BWP. A push transmission corresponds to one configured uplink grant. Alternatively, higher-level parameters may determine the allocation of time-domain resources.

[0453] Terminal device 1 may report (transmit) the CSI. The challenge is that the CSI is reported to... The source needs to be determined efficiently. This embodiment may be used to solve this problem. Figure 9 shows an example of a terminal startup beam report according to one aspect of this embodiment.

[0454] Terminal device 1 may receive a Downlink reference signal (DL RS) 900. Terminal device 1 may receive a Downlink reference signal 900. Terminal device 1 may receive a Downlink The downlink reference signal 900 may be received periodically or semi-permanently. The terminal device 1 does not have to receive the downlink reference signal 900 aperiodically. For example, if transmission means A is set, the terminal device 1 may receive the downlink reference signal 900 periodically or semi-permanently. If transmission means A is set, the terminal device 1 does not have to receive the downlink reference signal 900 aperiodicly. It is not necessary. For example, if transmission means B is configured, terminal device 1 may receive the downlink reference signal 900 periodically or semi-permanently. If transmission means B is configured, terminal device 1 does not need to receive the downlink reference signal 900 aperiodicly.

[0455] The downlink reference signal may be CSI-RS or an SS / PBCH block. It may also be NZP CSI-RS. The CSI-RS may be periodic CSI-RS or semi-persistent CSI-RS. For example, the time-domain operation in the CSI resource configuration may be set to 'periodic' or 'semi-persistent'. It is not expected that the time-domain operation in the CSI resource configuration will be set to 'aperiodic'. For example, when transmission means A is configured. The time-domain operation in the CSI resource settings may be set to 'periodic' or 'semi-persistent'. If transmission means A is set, it is not expected that the time-domain operation in the CSI resource settings will be set to 'aperiodic'. If transmission means B is set, the time-domain operation in the CSI resource settings may be set to 'periodic' or 'semi-persistent'. If transmission means B is set, it is not expected that the time-domain operation in the CSI resource settings will be set to 'aperiodic'. The time-domain operation in the CSI resource settings may be set by a higher-level parameter. The higher-level parameter may be resourceType. If neither transmission means A nor transmission means B is set, the CSI resource The time-domain behavior in the source configuration may be set to 'periodic', 'semi-persistent', or 'aperiodic'.

[0456] The downlink reference signal 900 may be related to the indicated TCI state. The downlink reference signal 900 may be related to the reference signal in the indicated TCI state. For example, the indicated TCI The state may include one or two QCL pieces of information. Each QCL piece of information indicates one reference signal. This is also fine. For example, one indicated TCI state is one reference signal and "physical channel and reference The QCL relationship with the "illumination signal" may also be indicated. Downlink reference signal 900 is one reference signal. That's fine.

[0457] Terminal device 1 may receive N downlink reference signals {901, ..., 901 + N-1}. Terminal device 1 may receive some or all of the downlink reference signals {901, 902, 903, 904, 905, 906, 907, 908}. Terminal device 1 may receive downlink reference signal 901 + n, where nb is an integer from 0 to N-1. The N downlink reference signals {901, ..., 901 + N-1} are different resources. It may also correspond to a resource ID (CSI-RS resource ID, or SSB index).

[0458] N may be the number of downlink reference signals included in the downlink reference signal set 911. N may also be the number of candidate beams. The number of candidate beams is determined by the upper layer parameters. It may be set. N may be any of 1, 2, 4, and 8.

[0459] In Figure 9, terminal device 1 may receive the downlink reference signal 901+n. For example, downlink The downlink reference signal 901+n may be any of the N downlink reference signals {901, ..., 901+N-1}. Terminal device 1 may periodically receive the downlink reference signal 901+n. If terminal device 1 periodically receives the downlink reference signal 900, terminal device 1 may periodically receive the downlink reference signal 901+n. If terminal device 1 semi-permanently receives the downlink reference signal 900, terminal device 1 may semi-permanently receive the downlink reference signal 901+n.

[0460] Terminal device 1 may calculate L1-RSRP. For example, terminal device 1 may calculate the downlink reference signal Alternatively, the L1-RSRP associated with the downlink reference signal set may be calculated. For example, downlink In response to the reception of a downlink reference signal, terminal device 1 may calculate the L1-RSRP corresponding to the downlink reference signal. For example, in response to the reception of a downlink reference signal set, terminal device 1 may calculate the downlink You may also calculate the L1-RSRP corresponding to the link reference signal set.

[0461] Terminal device 1 may calculate L1-RSRP. For example, L1-RSRP is calculated using the downlink reference signal. It may be determined based on the following. For example, one L1-RSRP is based on one downlink reference signal. The terminal device 1 may calculate or determine N L1-RSRPs corresponding to N downlink reference signals 901+n.

[0462] The downlink reference signal set 910 may include at least the downlink reference signal 900. The downlink reference signal set 910 may also be a reference signal set for beam fault detection. The downlink reference signal set 910 may also be a set of indicated TCI states.

[0463] The downlink reference signal set 911 may include downlink reference signals 901+n. The downlink reference signal set 911 may include N downlink reference signals {901, ..., 901+N-1}. Terminal device 1 may receive the downlink reference signal set 911. The downlink reference signal set 911 may be set by upper-layer parameters when events are used.

[0464] The downlink reference signal set 911 may include N downlink reference signals {901, ..., 901 + N - 1} and downlink reference signal 900. For example, when the upper layer parameter currentBeamReport is set, the downlink reference signal set 911 may include N downlink reference signals {901, ..., 901 + N - 1} and downlink reference signal 900. For example, when the upper layer parameter currentBeamReport is set, the downlink reference signal set 911 may include downlink reference signals 901 + n and downlink reference signal 900. When currentBeamReport is set, terminal device 1, You can expect the downlink reference signal set 911 to always include the downlink reference signal 900.

[0465] The upper layer parameter currentBeamReport determines whether the CSI940 contains at least one L1-RSRP. It may be determined that one L1-RSRP is associated with the downlink reference signal 900. If currentBeamReport is set, CSI940 may consist of at least M L1-RSRPs and one L1-RSRP. The M L1-RSRPs may be associated with M of the N downlink reference signals {901, ..., 901 + N - 1}. One L1-RSRP may be associated with the downlink reference signal 900.

[0466] If currentBeamReport is not set, the downlink reference signal set 911 may or may not include downlink reference signal 900. If currentBeamReport is not set, one of the N downlink reference signals {901, ..., 901+N-1} is downlink reference signal 90 It can be the same as 0.

[0467] If currentBeamReport is not set and the downlink reference signal set 911 includes the downlink reference signal 900, the CSI940 is configured with at least M L1-RSRPs and 1 L1-RSRP. This may be done if currentBeamReport is not set, and the downlink reference signal set If T911 does not include the downlink reference signal 900, CSI940 may consist of at least M L1-RSRPs. The M L1-RSRPs are part of the N downlink reference signals {901, ..., 901 + N-1}. They may be related. Some of them may not be related to the downlink reference signal 900. One L1-RSRP may be related to the downlink reference signal 900.

[0468] If currentBeamReport is not set, the CSI940 will be configured with at least M L1-RSRPs. If the downlink reference signal set 911 includes downlink reference signal 900, then each of the M L1-RSRPs may be associated with either the N downlink reference signals {901, ..., 901+N-1} or the downlink reference signal 900. For example, at least one of the M L1-RSRPs may be downlink The downlink reference signal 900 may also be associated with it. If the downlink reference signal set 911 does not include the downlink reference signal 900, then each of the M L1-RSRPs has N downlink reference signals {901, ..., 901 + N}. B It may also be related to any of the following: -1}

[0469] If currentBeamReport is not set, and the downlink reference signal set 911 includes downlink reference signal 900, then one of the M L1-RSRPs is associated with downlink reference signal 900. You may do so.

[0470] If currentBeamReport is not set, the downlink reference signal set 911 may not be expected to include the downlink reference signal 900. If currentBeamReport is not set, the CSI940 may not be expected to include one L1-RSRP. One L1-RSRP may be associated with the downlink reference signal 900. If currentBeamReport is not set, the downlink reference signal set 910 may include the downlink reference signal 900.

[0471] The CSI resource setting 920 may also configure the downlink reference signal set 910.

[0472] The CSI resource setting 921 may also configure the downlink reference signal set 911. The reference signal 901+n may be set by upper-layer parameters. The downlink reference signal 901+n may be set in the downlink reference signal set 911. For example, the downlink reference The illumination signal set 911 may include downlink reference signals 901+n. Upper layer parameters may be set for the downlink reference signal set 911. The downlink reference signals 901+n include CSI-RS, SSB, reference signals related to the set TCI state, and TCI state being activated. This may be part or all of the reference signal. n may be an integer from 0 to N-1.

[0473] The time-domain behavior in CSI resource setting 920 may be set by the higher-level parameter resourceType. The time-domain behavior in CSI resource setting 920 may be periodic ('periodic') or semi-persistent ('semi-persistent'). The time-domain operation is not expected to be aperiodic. The time-domain operation in CSI resource setting 921 is set by the higher-level parameter resourceType. The time domain operation in CSI resource setting 921 may be periodic or semi-persistent. The region operation does not necessarily have to be expected to be aperiodic.

[0474] The downlink reference signal 901+n may be associated with the activated TCI state. The downlink reference signal 901+n may be associated with the reference signal in the activated TCI state. For example, each activated TCI state may contain one or two QCL information. Each QCL information is one A reference signal may be indicated. For example, each activated TCI state may indicate a QCL relationship between a single reference signal and the “physical channel and reference signal”. Each of the downlink reference signals 901+n may be a single reference signal.

[0475] If the downlink reference signal 901+n is the first CSI-RS, then the downlink reference signal 900 may be the second CSI-RS. If the downlink reference signal 901+n is the first SS / PBCH block, then the downlink reference signal 900 may be the second SS / PBCH block.

[0476] The CSI report setting 930 may be linked to either or both of the CSI resource settings 920 and 921. Linking a parameter to a CSI resource setting is possible. The CSI resource settings may be set in the parameters. The fact that the data is linked to the CSI resource settings means that a BWP related to a certain parameter is linked to the CSI resource It may be the same as the BWP related to the settings.

[0477] The reporting volume setting may be set in the CSI report setting 930. Time-domain operation may be set in the CSI report setting 930. If transmission means B is set, time-domain operation does not need to be set in the CSI report setting 930. Both transmission means A and transmission means B are set. If not specified, the time-domain operation may be set to 'periodic', 'semi-persistent', or 'aperiodic'. If neither transmitting means A nor transmitting means B is set, the time-domain operation may be periodic, semi-persistent, or aperiodic. If transmitting means A is set If specified, the time-domain operation may be set to 'aperiodic'. If transmission means A is set, the time-domain operation may be aperiodic. If transmission means A is set, The time-domain operation is set to either 'semi-persistent' or 'periodic'. It is not necessary to expect that this will occur. When transmission means A is set, the time domain operation is periodic. or it does not need to be expected to be semi-permanent. When transmission means B is set, The time-domain operation may be set to 'semi-persistentOnPUSCH', 'periodic', or 'periodicOnPUSCH'. When transmission means B is set, it is not expected that either 'semi-persistentOnPUSCH' or 'aperiodic' will be set to the time-domain operation. This is also acceptable. When transmission means B is set, the time-domain operation is periodic or semi-permanent. It is acceptable. When transmission means B is set, it is expected that the time-domain operation is aperiodic. It is not necessary. If transmission means B is not set, it is not necessary to expect that 'periodicOnPUSCH' will be set in the time domain operation. It may also be related to relink grant. The time-domain operation is set to 'semi-persistent'. This may involve setting 'semi-persistentOnPUSCH' or 'semi-persistentOnPUCCH' in the time-domain operation. The failure to set both transmission means A and transmission means B may mean that terminal startup beam reporting is not set.

[0478] If the reporting volume setting in CSI report setting 930 is set to 'aperiodic', CSI940 This may be a non-periodic CSI. The reporting quantity setting is set to 'semi-persistentOnPUSCH'. If the reporting quantity setting is set to 'semi-persistentOnPUCCH', CSI940 may be a semi-persistent CSI, and CSI940 may be transmitted in PUCCH. If the reporting quantity setting is set to 'periodic', CSI940 may be a periodic CSI, and CSI940 may be transmitted in PUCCH. If the reporting quantity setting is set to 'periodicOnPUSCH', CSI940 may be a periodic CSI, and CSI940 may be transmitted in PUCCH. If the reporting quantity setting is set to 'periodicOnPUSCH', CSI940 may be a periodic CSI. It may be a periodic CSI, and CSI940 may be transmitted in a certain PUSCH. It may be scheduled by the configured uplink grant. The PUSCH may be configured for transmission by a higher-layer parameter, which may be configuredGrantConfig.

[0479] BWP950 is associated with either or both of CSI resource settings 920 and 921. It is permissible. BWP950 may also be associated with CSI report setting 930.

[0480] Serving cell 970 is either CSI resource setting 920 or CSI resource setting 921. Both may be related. Serving cell 970 may also be related to CSI report setting 930. .

[0481] Terminal device 1 may transmit CSI940. For example, if criterion 981 is met, terminal device 1 may transmit CSI940. If criterion 981 is not met, terminal device 1 transmits CSI940. You do not have to believe it. Criterion 981 may be at least related to event 980. Criterion 981 is fulfilled This can also be achieved by the occurrence of event 980. Criterion 981 is met if event 980 occurs N CIt may occur multiple times. Criterion 981 must be met once. In the time window, event 980 is N C It may occur multiple times. Criterion 981 is satisfied if event 980 for downlink reference signal 901+n occurs N C It may occur multiple times. Criterion 981 is satisfied if, within the time window, the downlink reference signal Event 980 for number 901+n is N C It may occur multiple times. Criterion 981 is satisfied. This means that event 980 is for at least one of the N downlink reference signals {901, ..., 901+N-1}. C It may occur multiple times. Criterion 981 is satisfied if the count value is N C It is also acceptable if the above conditions are met.

[0482] Terminal device 1 may detect an event, or the occurrence of an event. Device 1 may trigger an event. Terminal device 1 triggers event 980, evaluates it, and This may be detected. Terminal device 1 triggers event 980 based on L1-RSRP, evaluates, Alternatively, it may be detected.

[0483] When at least the downlink reference signal 901+n is received, terminal device 1 may verify or evaluate whether event 980 occurs or is satisfied. When the link reference signal 900 is received, terminal device 1 may verify or evaluate whether event 980 occurs or is fulfilled. If an event is detected, then the event The condition may occur or be met.

[0484] Event 980 is not valid even if the first L1-RSRP is equal to or exceeds the second L1-RSRP. Good. Event 980 occurs when the first L1-RSRP is equal to or exceeds the second L1-RSRP. It may be the case that the first L1-RSRP is the L1-RSRP of the downlink reference signal 901+n. This is also possible. For example, in event 980 for downlink reference signal 901+n, the first L1-RSRP The first L1-RSRP may be the L1-RSRP of the downlink reference signal 901+n. The first L1-RSRP may be at least one L1-RSRP from N downlink reference signals {901, ..., 901+N-1}. The second L1-RSRP may be the L1-RSRP based on the downlink reference signal 900. For example, the second L1-RSRP may be the sum of the L1-RSRP of the downlink reference signal 900 and a threshold. The threshold may be set by a higher-layer parameter. The threshold may be set in the CSI report setting 930. Event 980 may correspond to the CSI report setting 930. In event 980 for the number, the first L1-RSRP is the L1-RSRP of the downlink reference signal. That's fine.

[0485] The CSI940 may consist of at least M L1-RSRPs, or M+1 L1-RSRPs. At least one of the M+1 L1-RSRPs is an L1-RSRP associated with the downlink reference signal 900. It is also possible that terminal device 1 calculates L1-RSRP for a certain downlink reference signal and L1-RSRP You may report this.

[0486] If at least RSRP is set in the reporting volume setting, CSI may include L1-RSRP. Setting RSRP in the reporting volume setting means that the reporting volume setting is a beam report initiated by the terminal. It may be set. If transmission means A or transmission means B is used, CSI may include L1-RSRP.

[0487] The CSI940 may include at least M L1-RSRPs. The M L1-RSRPs include N downlinks. It may also relate to M downlink reference signals from the reference signals {901, ..., 901+N-1}. For example Even if N L1-RSRPs are calculated based on N downlink reference signals {901, ..., 901+N-1}, Good. M L1-RSRPs may be selected from N L1-RSRPs, where M is determined by nrofReportedRS. That decision is acceptable.

[0488] Terminal device 1 may perform either transmission means A or transmission means B. For example, if event 980 is set, either or both of transmission means A and transmission means B may be set. For example, if criterion 981 is met, terminal device 1 may perform either transmission means A or transmission means B. Transmission means A and transmission means B may be means for transmitting CSI 940. Setting the transmission of CSI 940 may mean setting either transmission means A or transmission means B. Which of transmission means A or transmission means B is performed may be set by a higher-level parameter. The higher-level parameter may be set for the CSI report setting 930. Transmission means A or transmission means B may be set for the reporting amount setting.

[0489] Terminal device 1 transmits via uplink physical channel 990 and uplink physical channel 991. It is permissible to send a message. In transmission means A, terminal device 1 may receive DCI1010. For example, transmission In means A, terminal device 1 may receive PDCCH on which DCI1010 is located. In transmission means B, Terminal device 1 does not need to expect to receive DCI1010. Transmitting means B, terminal device Placement 1 does not need to expect to receive PDCCH where DCI1010 is located.

[0490] In transmission means A, the uplink physical channel 990 may be PUCCH. Channel 990 may contain at least a scheduling request. A scheduling request may be part of or all of the UCI. This could be a request to schedule uplink physical channel 991. A scheduling request may consist of 1 bit. If Est indicates 0, the uplink physical channel 991 does not need to be scheduled. If the scheduling request indicates 0, the uplink physical channel 991 does not need to be scheduled. If the scheduling request indicates 1 In this case, the uplink physical channel 991 may be scheduled. If the request indicates 1, scheduling of the uplink physical channel 991 may be requested. If an event is detected, the scheduling request may be set to 1. If no event is detected, the scheduling request may be set to 0.

[0491] In transmission means B, the uplink physical channel 990 may be PUCCH. Channel 990 may include at least notification information. This notification information may be part or all of the UCI. The notification information is for notifying transmission on the uplink physical channel 991. This may also be the case. The notification information may consist of 1 bit. If the notification information indicates 0, terminal device 1 does not need to transmit on the uplink physical channel 991. If the notification information indicates 1, Terminal device 1 may transmit on the uplink physical channel 991. If an event is detected, the notification information may be set to 1. If no event is detected, the notification information may be set to 0.

[0492] In transmission means A, terminal device 1 may receive DCI1010. In transmission means A, terminal device 1 may receive PDCCH on which DCI1010 is located. In transmission means B, terminal device 1 does not have to receive DCI1010. DCI1010 may instruct transmission on uplink physical channel 991. DCI1 010 may schedule the uplink physical channel 991. The CSI request field in DCI1010 may instruct transmission on the uplink physical channel 991. The CSI request field in DCI1010 may schedule the uplink physical channel 991.

[0493] The CSI request field may indicate one trigger state. Transmission means A is set. If so, the CSI request field may indicate one trigger state from the first list. If transmission means A is set, the CSI request field may indicate one from the second list. It is not expected that the trigger state will be indicated. If neither transmission means A nor transmission means B is set, the CSI request field will be one of the first list and the second list. One trigger state may be indicated from either side. If transmission means B is set, CSI request The field indicates one trigger state from either the first list or the second list. It is not expected that this will happen. The first list is a list of trigger states for non-periodic CSIs. It may also be [this]. The first list is the upper-level parameter CSI-AperiodicTriggerStateList. The second list may also be a trigger state list for semi-persistent CSIs. The second list may be the upper-level parameter CSI-SemiPersistentOnPUSCH-TriggerStateList.

If the CSI report setting 930 corresponds to transmission means A, terminal device 1 may transmit the uplink physical channel 990. If the CSI report setting 930 corresponds to transmission means A, terminal device 1 may use the latest uplink physical channel 990. If the CSI report setting 930 corresponds to transmission means A, terminal device 1 transmits the uplink physical channel 991 based on the latest uplink physical channel 990. It may be transmitted. If the CSI report setting 930 corresponds to transmission means A, the terminal device 1 may transmit the CSI 940 based on the latest uplink physical channel 990. For example, the latest uplink Downlink reference signals {900, 901, ..., 901+N-1} received before link physical channel 990 Based on this, CSI940 may be reported. CSI report setting 930 does not correspond to transmission method A. In this case, terminal device 1 may transmit CSI without relying on the uplink physical channel 990. The CSI does not have to be associated with the downlink reference signals {900, 901, ..., 901+N-1}. If one trigger state is associated with the CSI report setting 930, terminal device 1 may transmit the uplink physical channel 991. If one trigger state is not associated with the CSI report setting 930, terminal device 1 does not have to transmit the uplink physical channel 991. If it is related to setting 930, terminal device 1 may send CSI940. If one trigger state is not related to CSI report setting 930, terminal device 1 does not need to send CSI940.

If transmission means A is configured, semi-persistent CSI-RS may be combined with aperiodic CSI report configurations. If transmission means A is configured Semi-persistent CSI-RS is not combined with semi-persistent and periodic CSI reporting settings. This is also acceptable. If transmission means B is configured, periodic CSI-RS may be combined with periodic CSI report configuration. If transmission means B is configured, periodic CSI-RS may be semi-permanent and non-permanent. It does not need to be combined with periodic CSI report settings. If transmission method B is set, semi-permanent Continuous CSI-RS may be combined with periodic CSI reporting settings. When transmission means B is configured, semi-persistent CSI-RS is combined with semi-persistent and non-periodic CSI reporting settings. It's not necessary.

[0503] If transmission means B is set, the first time-domain operation may be periodic. If transmission means B is set, the first time-domain operation may be 'periodic' or 'periodicOnPUSCH'. It may be set. When transmission means B is set, the first time-domain operation is aperiodic. This does not need to be expected. If transmission means B is set, it does not need to be expected that 'aperiodic' is set in the first time domain operation. If transmission means B is set, the A time-domain operation may be set to 'semi-persistentOnPUSCH', and a CSI may be sent based on the configured uplink grant setting.

[0504] If neither transmitting means A nor transmitting means B is set, the first time-domain operation may be periodic, semi-persistent, or aperiodic. If neither transmitting means A nor transmitting means B is set, the first time-domain operation may be set to 'periodic', 'semi-persistentOnPUCCH', 'semi-persistentOnPUSCH', or 'aperiodic'. If neither means A nor transmission means B is configured, it is not expected that 'periodicOnPUSCH' will be set in the first time-domain operation. If 'periodicOnPUSCH' is set in the first time-domain operation, the CSI report may be based on the configured uplink grant settings (e.g., configuredGrantConfig).

[0505] CSI may be transmitted on the uplink physical channel. Transmission means A or transmission means B If this is set, the uplink physical channel may be PUSCH. If neither transmitting means A nor transmitting means B is set, the uplink physical channel may be PUSCH or PUCCH. It's okay to have it.

[0506] The second time-domain operation of the downlink reference signal (e.g., resourceType) is determined by the CSI resource settings. It may be set in the default. The CSI report setting may be linked to the CSI resource setting. If transmission means A or transmission means B is set, the second time-domain operation may be periodic. If transmission means A or transmission means B is set, the second time-domain operation is not expected to be aperiodic. If neither transmission means A nor transmission means B is set, the second time-domain operation may be periodic, semi-persistent, or aperiodic. The second time-domain operation being periodic may be set to 'periodic'. The second time-domain operation being semi-persistent may be set to 'semi-persistent'.

Terminal device 1 may transmit a first uplink The link physical channel may be transmitted. Terminal device 1 transmits to the second uplink physical channel. CSI may be transmitted in this location. The first uplink physical channel is the uplink physical channel It may also be channel 990. The second uplink physical channel may also be uplink physical channel 991.

[0508] The CSI may be calculated based on the downlink reference signal. The CSI may be CSI940. The downlink reference signal may be any of the downlink reference signals {900, 901, ..., 901+N-1}. One CSI report setting may be set for the CSI. The port setting may also be CSI report setting 930.

[0509] The first list and either or both of the second list may be configured in CSI-MeasConfig. CSI-MeasConfig may configure one or more CSI reporting settings. The first list may be a trigger state list for aperiodic CSIs. The second list The list may be a trigger state list for a semi-persistent CSI. The first list may be set by aperiodicTriggerStateList. The second list may be semiPersistentOnPUSCH-TriggerStateList.

[0510] A trigger state may be associated with at least one CSI report setting. DCI is one The trigger state may also be indicated. For example, the CSI request field in DCI is one You may also indicate the trigger state.

[0511] If transmission means A is set, DCI may indicate one trigger state from the first list. Good. When transmission means A is set, DCI indicates one trigger state from the second list. This is not expected. If transmission means A is not set, the DCI may indicate one trigger state from the first or second list. If transmission means B is set, the PDCCH on which the DCI is located does not need to be received.

[0512] The first uplink physical channel may also be used to request the transmission of CSI. i. A second uplink physical channel may transmit to propagate the CSI. One CSI report setting may be set for the CSI. The DCI may indicate one trigger state. One trigger state may be associated with at least one CSI report setting. If transmission means A is set, the CSI is calculated, determined, or based on the first uplink physical channel. It may be transmitted. If transmission means A is not configured, the CSI may not be expected to be based on the first uplink physical channel. If transmission means A is not configured, the CSI may calculate, determine, or transmit without being based on the first uplink physical channel.

[0513] For example, the CSI is calculated based on the first uplink physical channel, and the downlink The CSI may be received before the first uplink physical channel. The CSI may be calculated based on the downlink reference signal. For example, if the CSI is calculated based on the first uplink physical channel, one CSI report setting may include a setting for the first uplink physical channel, or a setting ID for the first uplink physical channel. This means that one CSI report setting and the first uplink physical channel will be affected by the same event. For example, event 980), or related to the same event ID (for example, the ID of event 980) It may also be the case that the CSI calculates based on the first uplink physical channel. This may involve one CSI report setting being linked to the settings for the first uplink physical channel.
