At least CP-OFDM (Cyclic Prefix - Orthogonal Frequency Division Multiplex) is used on the downlink. CP-OFDM is used on the uplink. Either CP-OFDM or DFT-s-OFDM (Discrete Fourier Transform - spread - Orthogonal Frequency Division Multiplex) is used. DFT-s-OFDM is different from CP-OFDM. 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.

[0018] The base station device 3 may provide one or more serving cells. A serving cell may be defined as a set of resources used for wireless communication. A serving cell is also referred to as a cell.

[0019] A serving cell consists of one downlink component carrier (downlink carrier) and one uplink component carrier (uplink carrier). 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 given for each component carrier. Also, one resource grid may be given for each set of a component carrier and a subcarrier spacing configuration μ. Here, the subcarrier spacing configuration μ is also referred to as numerology. For example, one resource grid may be given for a set of a certain antenna port p, a certain subcarrier spacing configuration μ, and a certain transmission direction x.

[0021] The resource grid contains N size,μ grid,x N RB sc subcarriers. Here, the reso -urce grid starts from the common resource block N start,μ grid,x . Also, the common resource block N start,μ grid,x is also referred to as the reference point of the resource grid.

[0022] The resource grid contains N subframe,μ symb OFDM symbols.

For example, the subscript x may be used to indicate either the downlink or the uplink. For example, the subscript x may be used to indicate either the downlink or the uplink.

[0024] N size,μ grid,x is indicated by a parameter provided by the RRC layer (e.g., the parameter CarrierBandwidth) offset setting. N is the band setting indicated by a parameter provided by the RRC layer (e.g., the parameter, OffsetToCarrier). start,μ grid,x is the band setting indicated by a parameter provided by the RRC layer (e.g., the parameter, OffsetToCarrier). ​Offset setting and bandwidth setting refer to the configuration of the SCS-specific carrier. This is the setting used.

[0025] Subcarrier Spacing (SCS) for a given subcarrier spacing μ )Δf is Δf=2 μ It may also be 15kHz. Here, the setting μ for the subcarrier interval is 0 It may represent 1, 2, 3, or 4.

[0026] Figure 2 shows the subcarrier spacing setting μ and the number of OFDM symbols per slot N according to one aspect of this embodiment. slot symb This is an example illustrating the relationship between the cyclic prefix (CP) setting and the subcarrier spacing μ is 2, and the CP setting is normal CP (normal cyclic prefix). slot symb =14, N frame,μ slot =40, N subframe, μ slot = 4. Also, in Figure 2B, for example, if the subcarrier spacing μ is set to 2, Furthermore, if the CP setting is an extended cyclic prefix, N slot symb =12, N frame ,μ slot =40, N subframe,μ slot = 4

[0027] Time unit (T) c This may be used to represent length in the time domain. Time unit T c is, T c = 1 / (Δf max ·N f ) is Δf max= 480kHz. f =409 The answer is 6. The constant κ is given by κ = Δf max ·N f / (Δf ref N f,ref ) = 64. Δf ref is, 1 It is 5kHz. f,ref The answer is 2048.

[0028] The transmission of a signal on the downlink and / or the uplink is of length T. f It may be organized into wireless frames (system frames, frames). f =(Δf max N f / 100)·T s = 10ms. 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.

[0029] An OFDM symbol is a time-domain unit of a communication scheme. For example, an OFDM symbol may be a time-domain unit of CP-OFDM. Alternatively, an OFDM symbol may be a time-domain unit of DFT-s-OFDM.

[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, Nslot symb =12 is also acceptable.

[0031] For a certain subcarrier interval setting μ, the number of slots and their indices within the subframe may be given. 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. Also, slot index n μ s,f In wireless frames, the range is 0 to N frame,μ slot The integer values ​​may also be given in ascending order within the range of -1.

Figure 3 shows an example of a resource grid configuration with a subcarrier spacing μ1 in a component carrier 300, and an example of a resource grid configuration with a subcarrier spacing μ2 in a certain component carrier. In this way, one or more subcarrier spacings may be set for a given component carrier. In Figure 3, it is assumed that μ1 = μ2 - 1, but the various aspects of this embodiment are not limited to the condition μ1 = μ2 - 1.

[0033] The component carrier 300 is a bandwidth having a predetermined width in the frequency domain.

[0034] Point 3000 is an identifier used to identify a specific subcarrier. Point 3000 is also called Point A. Common resource block (CRB) set 3100 is a common resource block for setting the subcarrier interval μ1. It's a rock set.

[0035] Among the common resource block set 3100, the common resource block containing point 3000 (the black block in the common resource block set 3100 in Figure 3) is also referred to as the reference point of the common resource block set 3100. The reference point of the common resource block set 3100 may be the common resource block at index 0 in the common resource block set 3100.

[0036] Offset 3011 is the offset from the reference point of the common resource block set 3100 to the reference point of the resource grid 3001. Offset 3011 is indicated by the number of common resource blocks relative to the subcarrier spacing setting μ1. The resource grid 3001 starts from the reference point of the resource grid 3001. size,μ grid1,x Includes several common resource blocks.

[0038] The common resource block set 3200 is a common resource for setting the subcarrier interval μ2. This is a set of source blocks.

[0039] Among the common resource block set 3200, the common resource block containing point 3000 (the solid black block in the common resource block set 3200 in Figure 3) is also referred to as the reference point of the common resource block set 3200. The reference point of the common resource block set 3200 may also be the common resource block with index 0 in the common resource block set 3200.

[0040] The offset 3012 is the offset from the reference point of the common resource block set 3200 to the reference point of the resource grid 3002. The offset 3012 is indicated by the number of common resource blocks with respect to the sub-carrier spacing μ2. The resource grid 3002 starts from the reference point of the resource grid 3002 and has N size,μ grid2,x common resource blocks included therein.

[0041] The offset 3014 is the offset from the reference point of the resource grid 3002 to the reference point of the BWP 3004 of index i2 (N start,μ BWP,i2 ).

In the resource grid of FIG. 4, the horizontal axis is the OFDM symbol index l sym and the vertical axis is the sub-carrier index k sc . The resource grid 3001 includes N size,μ grid1,x N RB sc sub-carriers and N subframe,μ symb OFDM symbols. In the resource grid, the resource specified by the sub-carrier index k and the OFDM symbol index l sc is also referred to as a resource element (RE). sym A resource block (RB) includes N

[0043] [[ID=3&]] consecutive sub-carriers RB sc and is one of a common resource block, a physical resource block (PRB), and a virtual resource block (VRB). It is a general term. Here, N RB sc = 12.

[0044] A resource block unit is a set of resources corresponding to 1 OFDM symbol in one resource block. That is, one resource block unit contains 12 resource elements corresponding to 1 OFDM symbol in one resource block.

[0045] The common resource blocks for a certain subcarrier spacing setting μ are indexed in ascending order from 0 in the frequency domain in a certain common resource block set. The common resource block with index 0 for a certain subcarrier spacing setting μ contains (or collides with, coincides with) point 3000. The index n of the common resource block for a certain subcarrier spacing setting μ μ CRB is n μ CRB = ceil(k sc / N RB sc ) satisfies the relationship. Here, k sc = 0 subcarriers have the same center frequency as the center frequency of the subcarriers corresponding to point 3000 .

[0046] The physical resource blocks for a certain subcarrier spacing setting μ are indexed in ascending order from 0 in the frequency domain in a certain BWP. The index n of the physical resource block for a certain subcarrier spacing setting μ is n μ PRB = n μ CRB = n μ PRB + N start,μ BWP,i ) satisfies the relationship. Here, N start,μ BWP,i indicates the reference point of the BWP with index i.

The BWP is defined as the reference point N of the BWP. start,μ BWP,i N starting with size,μ BWP,i Individual common lith Includes the link block. The BWP set for the downlink carrier is also called the downlink BWP. The BWP set for the uplink component carrier is also called the uplink BWP.

[0048] An antenna port may be defined such that the channel over which a symbol on the antenna port is conveyed can be inferred from the channel over which another symbol on the same antenna port is conveyed. 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.

[0049] The fact that the large-scale properties of a channel through which symbols are transmitted in one antenna port can be estimated from the channels through which symbols are transmitted in another antenna port is referred to as QCL (Quasi Co-Located). 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). Terminal device 1 assumes that the two antenna ports are QCLs if the large-scale characteristics of the channel through which symbols are transmitted at one antenna port can be estimated from the channel through which symbols are transmitted at the other antenna port. It is also acceptable to assume that two antenna ports are QCLs. Large-scale characteristics may also be referred to as QCL parameters. stomach.

[0050] The QCL type may be any of type A, type B, type C, or type D.

[0051] Two antenna ports being type A QCLs may mean that the first large-scale characteristic of the channel through which symbols are transmitted in one antenna port can be estimated from the channel through which symbols are transmitted in the other antenna port. Two antenna ports being type B QCLs may mean that the second large-scale characteristic of the channel through which symbols are transmitted in one antenna port can be estimated from the channel through which symbols are transmitted in the other antenna port. Two antenna ports being type C QCLs may mean that the third large-scale characteristic of the channel through which symbols are transmitted in one antenna port can be estimated from the channel through which symbols are transmitted in the other antenna port. Two antenna ports being type D QCLs may mean that the fourth large-scale characteristic of the channel through which symbols are transmitted in one antenna port can be estimated from the channel through which symbols are transmitted in the other antenna port. The first large-scale characteristic may include Doppler shift, Doppler spread, mean delay, and delay spread. The second large-scale characteristic may include Doppler shift and Doppler spread. The third large-scale characteristic may include the Doppler shift and the mean delay. The fourth large-scale characteristic is the spatial reception parameter (spatial directional information, beam information). ) may include. The antenna port for DMRS may be a DMRS port.

In other words, the downlink component carrier on which the PDCCH scheduled by DCI format 1_0 is located is the downlink on which the PDCCH containing DCI format 1_0 is located. The downlink component carrier may be the same. Terminal device 1 detects DCI format 1_0 on a certain downlink component carrier and, based on that, assigns a PDSCH scheduled by DCI format 1_0 to the downlink component It may be acceptable to consider placing them on the carrier.

[0155] DCI format 1_0 does not have to include the BWP field. Here DCI format The format 1_0 may be a DCI format that schedules the PDSCH without changing the active downlink BWP. 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 at least for scheduling PDSCHs located in a given cell. DCI format 1_1 is used 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 to be scheduled is located. In other words, DCI format 1_1 may involve a change in the active downlink BWP. Terminal device 1 detects DCI format 1_1 used for scheduling the PDSCH. Therefore, the downlink BWP on which the PUSCH is located may be recognized.

[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 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 the upper 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.

[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. It 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. In other words, 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.

[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.

[0186] 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. .

[0187] 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.

[0188] 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.

[0194] SS / PBCH block candidates indicate resources that are permitted (possible, reserved, configured, specified, or potentially) to send SS / PBCH blocks.

[0195] 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.

[0196] 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.

[0206] 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).

[0207] 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).

[0208] 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.

[0209] 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.

[0210] 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.

The detected downlink DCI format is also called the downlink assignment. Terminal device 1 attempts to receive the PDSCH. Based on the PUCCH resource shown in DCI format, the HARQ-ACK corresponding to the PDSCH (HARQ-ACK corresponding to the transport block contained in the PDSCH) is reported to the base station device 3.

[0229] In uplink communication, terminal device 1 detects the uplink DCI format. The DCI format that is provided will be used at least for resource allocation in PUSCH. The detected uplink DCI format is also referred to as an uplink grant. Terminal device 1 transmits the PUSCH.

[0230] In configured grant scheduling, PUSCH is used in the scheduler The uplink grant to be set is configured for each transmission cycle of the PUSCH. When the PUSCH is scheduled using the uplink DCI format, some or all of the information indicated by the uplink DCI format may be indicated by the uplink grant configured for the scheduling.

[0231] The PUSCH transmission may correspond to the configured scheduling type 1 or the configured scheduling type 2. That is, the configured scheduling is 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. The `rrc-ConfiguredUplinkGrant` may also be configuredGrantConfig. For example, configuredGrantConfig may include rrc-ConfiguredUplinkGrant. The PUSCH transmission is for the uplink grant in DCI.

The system frame number may consist of 10 bits. At least a portion of the system frame number may be communicated in the MIB. For example, 6 bits of the 10-bit system frame number (e.g., 6 most significant bits) may be communicated in the MIB. At least a portion of the system frame number may be determined based on the PBCH for communicating the MIB. For example, a 10-bit system frame number Four bits of the stem frame number (for example, the four least significant bits) may be transmitted in the PBCH transport block as part of the channel coding.

Bundling operations may depend on HARQ entities. The same HARQ process may be invoked for each transmission that is part of the same bundle. Bundling operations may depend on HARQ entities to invoke the same HARQ process for each transmission that is part of the same bundle. After the initial transmission, a certain number of HARQ retransmissions may be performed. This number may be the value of the upper-layer parameter pdsch-AggregationFactor minus 1.

[0241] MAC entities may assign TB and HARQ information to HARQ processes. For example, downlink When a link assignment is instructed, the MAC entity sends TB and HARQ information to the HARQ process. It may be assigned to a . The HARQ process may be directed by HARQ information. The HARQ information may be related to TB. For example, the HARQ information may direct the TBS of TB. TB is physical It may be received from the layer. For example, if a downlink assignment is directed for a broadcast HARQ process, the MAC entity will receive the TB for the broadcast HARQ process. It may be assigned to that.

[0242] HARQ information may be HARQ information for DL-SCH, UL-SCH, or SL-SCH. HARQ information may consist of NDI (New Data Indicator), TBS (Transport Block Size), RV (Redundancy Version), and some or all of the HARQ process ID.

[0243] A transmission may be made in response to a HARQ process. For example, when a transmission is made in a HARQ process, one or two TBs and HARQ information may be received from the HARQ entity. The HARQ process may assume that a transmission is a new transmission. For example, if NDI is toggled, the HARQ process may assume that a transmission is a new transmission. It can be assumed that this exists. For example, for every TB, NDI may be the last received transmission corresponding to that TB. If it was toggled by comparing with the value, a certain transmission may be assumed to be a new transmission. For example, if the HARQ process is at least equal to the broadcast process, the HARQ process may assume a certain transmission is a new transmission. For example, the previous NDI for a certain TB If not, the HARQ process corresponding to a TB may assume that a transmission is a new transmission. A new transmission may be the initial transmission. If a transmission is not a new transmission, it may be a retransmission. For example, if NDI is not toggled, a transmission is You can resend it.

[0244] If a transmission is a new transmission, the MAC entity decodes the received data. You may try. If a transmission is a retransmission, the MAC entity will receive the data and the system The physical layer may be instructed to synthesize the data in the soft buffer. Titi may attempt to decode the synthesized data. The data may correspond to TB. The soft buffer may correspond to TB. The HARQ process may be equivalent to the broadcast process. If the decoding of some data is successful, the MAC entity is decoded. Decoded data (e.g., MAC PDU) may be transmitted to a higher layer. If decoding of some data fails In this case, the MAC entity instructs the physical layer to place the data in the soft buffer. It is also possible that a MAC entity may instruct the physical layer to generate ACKs (Acknowledgement(s)) for the data. A MAC entity may ignore NDI. For example, NDI is It may be received in all downlink assignments. It may be in a PDCCH in a downlink assignment. The PDCCH may correspond to a Temporary C-RNTI (TC-RNTI). For example, to determine if the NDI in a PDCCH corresponding to a C-RNTI is toggled, MAC address The NTP may ignore the NDI in the PDCCH corresponding to TC-RNTI. Toggle of NDI means that the NDI is toggled by comparing it to the value in the previous transmission.

The QCL relationship is 1 or 2 Relationship between two downlink reference signals (downlink physical signals) and the PDSCH's DMRS (DMRS port). The QCL relationship may also be a relationship between one or two downlink reference signals (downlink physical signals) and the DMRS (DMRS port) of the PDCCH. Link reference signal (downlink physical signal) and CSI-RS (CSI-RS port) for one CSI-RS resource. The relationship may also be as follows. For example, the QCL relationship between channel / signal A and channel / signal B is as follows: It may also be expressed that channel / signal A is QCL with channel / signal B.

[0303] 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.

[0307] If DLorJointTCIState or UL-TCIState is set, terminal device 1 may send PUSCH or PUCCH according to the spatial relation. For example, spatial relation The relationship may be based on a single reference signal (RS). For example, the single reference signal may be a reference signal for determining the uplink transmit space filter. In the “indicated TCI state”, typeD may be a reference signal set by qcl-Type. The “indicated TCI state” may be an indicated DLorJointTCIState or an indicated UL-TCIState.

Furthermore, it may be assumed that NDI is 0, that all values ​​are set to 0 for FDRA type 0, and that all values ​​are set to 1 for FDRA type 1, or some or all of these.

[0314] Terminal device 1 may receive a DCI format including a PRI field. The PRI field may select one or two TCI states from one or more “indicated TCI states”. The TCI state may also be referred to as the “applied TCI state”. If one TCI state is selected, one TCI state may be applied to PDSCH, PUSCH, PUCCH, CSI-RS, or SRS scheduled by the DCI format. If two TCI states are selected Two TCI states may be applied to PDSCH, PUSCH, PUCCH, CSI-RS, or SRS scheduled by the DCI format. The “indicated TCI state” may be the indicated DLorJointTCIState or the indicated UL-TCIState. Matt may also be referred to as DCI.

For example, N conf The TCI state may be set by higher-level parameters. conf Each of these TCI states is referred to as the “configured TCI state”. It's okay to do that. confThis can be an integer from 1 to 128. If the TCI state is a DL TCI state or a Joint TCI state, then N conf This can be an integer from 1 to 128. TCI state If it is in UL TCI state, N conf This can be an integer from 1 to 64.

[0316] N act The individual TCI states may be activated. For example, N act The number of TCI states is N conf This may be some or all of the TCI states. For example, N act Each TCI state corresponds to the media access control layer. It may be activated in N. act Each TCI state is activated by MAC CE. It's fine. act Each of these TCI states may also be referred to as an “activated TCI state.” act This can be an integer from 1 to 32.

For example, N ind The number of TCI states is N act Individual TCI states It may be part or all of N. ind Each TCI state is indicated at the physical layer. It is also acceptable. For example, N ind Each TCI state may be indicated by a DCI. For example, N ind Each TCI state may be indicated by the TCI field in DCI. indEach of the individual TCI states may be referred to as an “indicated TCI state.” An “indicated TCI state” may apply to PDSCH, PDCCH, and CSI-RS. An “indicated TCI state” may apply to PUSCH, PUCCH, and SRS. An “indicated TCI state” may apply to PDSCH, PDCCH, CSI-RS, PUSCH, PUCCH, and SRS. ind This can be an integer from 1 to 4.

For example, N app Each TCI state may be indicated at the physical layer or the wireless resource control layer. For example, N app Each TCI state may be indicated by a DCI. For example, N app Each TCI state corresponds to PRI in DCI. This may be indicated by a field. app Each of these TCI states may also be referred to as the “applicable TCI state”. app This can be 1 or 2.

[0319] Terminal device 1 may receive higher layer settings. Terminal device 1 is set to "TCI state". After it is determined, one of the "specified TCI states" is applied from the "set TCI state". Prior to this, 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. For example, after terminal device 1 has received the initial setting of multiple DLorJoint-TCIStates and before one of the configured TCI states 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.

[0320] Terminal device 1 may receive higher layer settings. Terminal device 1 is set to "TCI state". After it is determined, one of the "specified TCI states" is applied from the "set TCI state". Before that, terminal device 1 applies the “instructed TCI state” to the first uplink transmit space filter for PUSCH, PUCCH, and SRS, and the second uplink transmit space filter It can be assumed that it is the same as, for example, terminal device 1 has multiple DLorJoint-TCIState, Alternatively, after receiving the first setting of multiple UL-TCIStates, and from the set TCI state 1 Before the specified TCI state is applied, terminal device 1 applies the specified TCI state. It may be assumed that the first uplink transmit spatial filter (UL TX spatial filter) for PUSCH, PUCCH, and SRS used is the same as the second uplink transmit spatial filter. The second uplink transmit space filter is scheduled by random access response grants in the initial access procedure. It could also be an uplink transmission space filter for transmission.

[0321] After terminal device 1 has received multiple DLorJoint-TCIState settings ("set TCI states"), and before one "instructed TCI state" is applied from the set TCI states, The DMRS of the PDSCH, DMRS of the PDCCH, and CSI-RS to which the indicated TCI state applies may be an SS / PBCH block or a CSI-RS resource and QCL. For example, an SS / PBCH block or a CSI-RS resource may be identified in a random access procedure initiated by a synchronized reconfiguration. For example, terminal device 1 sets the DLorJoint-TCIState with a synchronized reconfiguration. It may be received as part of a reconfiguration with sync.

[0322] Terminal device 1 has multiple DLorJoint-TCIState or multiple UL-TCIState settings ("Settings After receiving a “TCI state that is specified”, and from the set TCI state, one “TCI state that is specified”. Prior to the application of the specified TCI state, the first uplink transmit space filter for PUSCH, PUCCH, and SRS may be assumed to be the same as the second uplink transmit space filter. The second uplink transmit space filter is the uplink transmit space filter for PUSCH transmits scheduled by random access response grants in random access procedures initiated by synchronized reconfiguration. That's fine.

[0323] DLorJoint-TCIState may be used as the “instructed TCI state”. For example, terminal Device 1 may obtain the QCL assumption (QCL relationship, QCL) from the "configured TCI state" for the PDSCH DMRS, PDCCH DMRS, and CSI-RS to which the "configured TCI state" applies. The "configured TCI state" is applied to the PDSCH DMRS, PDCCH DMRS, and CSI-RS. Good. The “indicated TCI state” may apply to DMRS of PDSCH, DMRS of PDCCH, CSI-RS, PUSCH, PUCCH, and SRS.

[0324] UL-TCIState may be used as the “instructed TCI state”. For example, terminal device 1 is For PUSCH, PUCCH, and SRS, which apply the “instructed TCI state,” the uplink transmit space filter may be determined from the “configured TCI state.”

[0325] When 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. The HARQ-ACK information may be HARQ-ACK information corresponding to a DCI that transmits a TCI state indication without a downlink assignment. The HARQ-ACK information may also be HARQ-ACK information corresponding to a PDSCH scheduled by a DCI that transmits a TCI state indication. The second indicated TCI state may be indicated before the first indicated TCI state. The first slot is the first slot of the first channel. The first slot after the beamAppTime symbol may be at least the number of OFDM symbols after the subsequent OFDM symbol. BeamAppTime may be the number of OFDM symbols. BeamAppTime may be set by a higher-layer parameter. BeamAppTime may be determined by terminal capability. The indicated TCI state may be the indicated DLorJointTCIState or the indicated UL-TCIState. The indicated TCI state is until the end of the PUCCH or PUSCH that transmits HARQ-ACK information. It may be valid.

[0326] If the upper-level parameter PDCCH-Config contains two different values ​​for the CORESET Pool Index (or coresetPoolIndex), terminal device 1 may receive activation commands ("Activated TCI States") for each CORESET associated with the CORESET Pool Index. The activation commands may be used to map up to eight TCI states to code points in the DCI field 'Transmission Configuration Indication'. If a set of TCI state IDs is activated for one CORESET Pool Index, the "Activated TCI States" corresponding to that CORESET Pool Index are associated with one physical cell ID. It is also possible to use a different CORESET pool index from the 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. One or Multiple CORESETs may be configured. A single CORESET may correspond to a CORESET pool index of '0' or '1'.

[0327] One code point in the DCI field 'Transmission Configuration Indication' is It may include up to four TCI states. For example, one of the up to four TCI states may be a Joint TCI state. One of the up to four TCI states may be a DL TCI state. One of the up to four TCI states may be a UL TCI state. One code point in the DCI field 'Transmission Configuration Indication' may include two “pairs of TCI states” This is also acceptable. A pair of TCI states may be a pair of a DL TCI state and an UL TCI state. Terminal device 1 may receive an activation command. An activation command can contain up to 8 TCI states, with 4 or fewer states. The combination may be used to map to the code point of the DCI field 'Transmission Configuration Indication'. The activation command is one or two 'TCI states'. Up to eight combinations of the pairs of " may be used to map to the code map of the DCI field 'Transmission Configuration Indication'. Terminal device 1 does not need to expect to receive more than eight TCI states in the activation command. Terminal device 1 is activated In the transformation command, you do not need to expect to receive more than 8 "TCI state pairs".

[0328] 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.

[0329] If the first upper layer parameter is set, and the first time offset is greater than or equal to the first value, and terminal device 1 is the first setting of the TCI state (set After receiving the TCI state (which is to be activated), and after receiving the activation command (which is to be activated TCI state), Before being transmitted, the DMRS port of the PDSCH is connected to the SS / PBCH block and QCL with respect to QCL type A. This may also be the case. The first upper layer parameter may be set for a CORESET that schedules the PDSCH. The CORESET may schedule the PDSCH. The first time offset may be the offset between the reception of the DL DCI and the PDSCH. The first value may be timeDurationForQCL.

[0330] 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 first upper-layer parameter may also be tci-PresentDCI-1-2.

[0331] 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 instructed 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 instructed TCI state. For example, when a TCI state setting (a TCI state to be set) with DLorJointTCIState or UL-TCIState is set, 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 instructed TCI state. The first terminal capability is '1'. It may also be a beamCorrespondenceWithoutUL-BeamSweeping.

[0332] In periodic CSI-RS and semi-persistent CSI-RS, The indicated TCI state (e.g., the indicated DLorJointTCIState) does not have to be applied.

[0333] Terminal device 1 is a PDSCH scheduled by PDCCH with DCI format. DMRS may be received. If two TCI states are indicated and terminal device 1 receives the DMRS and SS / PBCH block for PDSCH in the same OFDM symbol, then at least one for PDSCH The DMRS port and SS / PBCH block may be QCL with typeD('QCL-TypeD'). If the first upper layer parameter is set and multiple PDSCHs overlap in the time-frequency domain due to multiple PDCCHs, different DMRS settings may not be expected, and two TCI states may not indicate a DMRS port within a single CDM group. The first upper layer parameter may be PDCCH-Config, which includes two different CORESET pool indices.

[0334] On the downlink, a maximum of 16 or 32 HARQ Pros can be used in a single serving cell. Seth may be supported. The number of HARQ processes may be set by a higher-level parameter. If no higher-level parameter is set, the number of HARQ processes may be 8. stomach.

PDCCHs that schedule two PDSCHs (the first PDSCH and the second PDSCH) may be associated with CORESETs having different CORESET pool index values. The upper layer parameter may be PDCCH-Config. Terminal device 1 may receive the first PDSCH and the second PDSCH.

The first PDSCH is SI-RNTI, P-RNTI, blow The G-RNTI may be used for scheduling for docasting. Terminal device 1 may assume that the DMRS port of the second PDSCH is the second SS / PBCH block or the second CSI-RS resource and QCL with respect to the first QCL parameter. The second SS / PBCH block or the second CSI-RS resource may be used for RACH-related purposes. The second PDSCH is used with RA-RNTI and MSGB-RNTI. It may be scheduled. Terminal device 1 has a DMRS port for the first PDCCH order and a DMRS port for the third PDSCH, and a second SS / PBCH block with respect to the first QCL parameter, Alternatively, it may be assumed that there is a second CSI-RS resource and QCL. The third PDSCH may be scheduled in RA-RNTI for random access procedures triggered by the first PDCCH order. The first QCL parameters may include some or all of the Doppler shift, Doppler spread, average delay, delay spread, and spatial RX parameters.

[0339] If the first upper layer parameter is set, terminal device 1 may receive multiple PDCCHs. The first upper layer parameter may be PDCCH-Config. The first upper layer parameter may include two different CORESET pool index values. Multiple PDCCHs are multiple The PDSCH may be scheduled. Multiple PDSCHs may or may not overlap in the time-frequency domain. If multiple PDSCHs are associated with different CORESETs, terminal device 1 may receive multiple PDSCHs simultaneously. Different CORESETs may have different CORESET pool index (coresetPoolIndex) values.

[0340] CORESET (upper layer parameter ControlResourceSet) is CORESET pool index (upper layer If the parameter coresetPoolIndex is not included, terminal device 1 may assume that CORESET is assigned a CORESET pool index of 0.

[0341] The first physical cell ID associated with the first CORESET may be different from the second physical cell ID associated with the second CORESET. For example, via the activated TCI state, the first CORESET and the second CORESET may be associated with different physical cell IDs. It may also support different CORESET pool indexes.

[0342] If the PDCCH reception contains two candidate PDCCHs from the search region set, monitor one PDCCH. The monitoring occasion may be the union of PDCCH monitoring occasions for two PDCCH candidates. The start of PDCCH reception may also be the start of the first PDCCH candidate. Furthermore, the termination of PDCCH reception may also be the termination of a subsequent PDCCH candidate.

The two TCI states indicate the QCL information (QCL relationship) of the DMRS antenna port for PDCCH reception. You may do so.

[0347] If no TCI state setting is provided in one CORESET, or if there are two or more TCI states If initial settings are provided and no MAC CE activation command is received, terminal device 1 may assume that the DMRS antenna ports associated with PDCCH reception are the SS / PBCH block and QCL. The SS / PBCH block may be identified by terminal device 1 during the initial access procedure.

[0348] If, in a single CORESET, two or more TCI state settings are provided by reconfiguration with synch, and a MAC CE activation command is not received, terminal device 1 will determine that the DMRS antenna port associated with PDCCH reception is in the SS / PBCH block or CSI-RS block. It may be assumed that these are resources and QCLs. The SS / PBCH block or CSI-RS resource is identified by terminal device 1 in a random access procedure initiated by a synchronized reconfiguration. It's okay.

[0349] In a CORESET with index 0, if a TCI state (e.g., a unified TCI state) is provided and the unified TCI state is applied, terminal device 1 will use a DMRS antenna for first PDCCH reception. It may be assumed that the naport (DMRS port) and the DMRS antenna port for the first PDSCH reception are the reference signal and QCL indicated by the TCI state. The application of the Unified TCI state may be that followUnifiedTCIstate is set to 'enable'. The PDSCH reception is scheduled by the DCI format provided by the first PDCCH reception. It may be linked. The unified TCI state may also be DLorJoint-TCIState.

[0350] In a CORESET with index 0, if a TCI state (e.g., unified TCI state) is provided and the unified TCI state is not applied, terminal device 1 will perform a DMRS annealing for the first PDCCH reception. The tenaport (DMRS port) is activated by one or more reference signals and QCL depending on the TCI state. It's okay to have it.

[0351] In a CORESET with an index other than 0, if one TCI state is provided, or if a MAC CE activation command is received for one or two provided TCI states, the terminal Device 1 may assume that the DMRS antenna port for PDCCH reception is one or more DL RS and QCL as set by the TCI state. The TCI state indicated by the MAC CE activation command may be the “Activated TCI state”.

[0352] If a unified TCI state is provided, PDCCH in one CORESET with an index other than 0 The DMRS antenna port for receiving and the DMRS antenna port for PDSCH scheduled by the DCI format provided by the PDCCH reception are indicated The reference signal may be provided by a TCI state ("indicated TCI state") and QCL.

[0353] If multiple (e.g., two) unified TCI states are provided (or indicated), then index 0 and above In a single CORESET with an external connection, a DMRS antenna port for PDCCH reception and a DMRS antenna port for PDSCH scheduled by the DCI format provided by said PDCCH reception may be QCL and a reference signal provided by one or both of the indicated unified TCI states ("indicated TCI states").

[0354] When a unified TCI state is applied, PDCCH occurs in one CORESET with an index other than 0. The DMRS antenna port for receiving and the DMRS antenna port for PDSCH scheduled by the DCI format provided by the PDCCH reception are indicated The reference signal may be provided by a TCI state ("indicated TCI state") and QCL.

[0355] In one BWP within one serving cell, a set of 10 or fewer search regions is provided. This is also possible. For each set of search domains, the first upper layer parameter determines the search domain set index, the second upper layer parameter determines the relationship between the search domain set and CORESET, and the third The search space set (search space set index) linked by the higher-level parameters may be determined to at least. The first higher-level parameter is searchSpaceId. This is also possible. The second higher-level parameter may be controlResourceSetId. In the first search space set, the second search space set index may be provided by the third higher-level parameter. The third higher-level parameter may link the first search space set and the second search space set. The third higher-level parameter may be searchSpaceLinking. The provision of the third higher-level parameter may mean that search space linking is applied.

[0356] When the first search area set and the second search area set are linked, terminal device 1 may monitor according to each search area set in a monitoring opportunity in one slot. The count of PDCCH candidates corresponding to the first search area set and the second search area set may be 3. The CORESET pool index for the first CORESET associated with the first search area set is the CORESET pool index for the second CORESET associated with the second search area set. The combination may differ from the original. The linking of the first set of search spaces and the second set of search spaces may mean that the first set of search spaces includes a searchSpaceLinking that includes the second set of search spaces, and the second set of search spaces includes a searchSpaceLinking that includes the first set of search spaces.

[0357] If the first search area set and the second search area set are linked, and the third search area set is not linked, terminal device 1 may monitor the first PDCCH candidate corresponding to the first search area set for the first DCI format, and the second search area The terminal device 1 may monitor a second PDCCH candidate corresponding to the region set. Alternatively, for the second DCI format, the terminal device 1 may monitor a third PDCCH candidate corresponding to the third search region set. Furthermore, in one CORESET, and for the same symbol in one slot... Then, the first PDCCH candidate corresponding to the first search region set, or the second search region set The second PDCCH candidate corresponding to the first set and the third PDCCH candidate corresponding to the third search region set may use the same set of CCEs and may undergo the same scrambling. The third PDCCH candidate corresponding to the third search region set is counted for monitoring. It is not necessary. Furthermore, the detected DCI format does not necessarily have to be assumed to be the first DCI format.

[0358] If the first search area set and the second search area set are linked, and the third search area set and the fourth search area set are linked, and the detected DCI format If the coreset sizes are the same, terminal device 1 may expect different CCEs or different scrambling in a single coreset.

[0359] When a terminal device monitors multiple PDCCHs in the first CORESET and the second CORESET, The first CORESET may correspond to a CSS set with the smallest index, or to a USS set with the smallest index. The second CORESET is the same as the first CORESET. It may have the 'typeD' property. Repeats may be applied for PDCCH. The application of repeats for PDCCH is provided by two-QCLTypeDforPDCCHRepetition. It is acceptable to do so.

[0360] If the first search area set and the second search area set are linked, terminal device 1 may detect from the two PDCCH receptions that the one terminating later is in DCI format.

[0361] MAC PDU (MAC protocol data unit) is a byte-aligned (byte-aligned) file. A MAC SDU (MAC service data unit) may be a bit string of byte-aligned (i.e., a multiple of 8 bits) bit array. A MAC SDU may consist of bits from the first bit onward of a MAC PDU. A MAC CE may consist of bits from byte-aligned (i.e., a multiple of 8 bits) bit array. The MAC subheader may be a bit string of a multiple of 8 bits. The MAC subheader may be a bit string of byte-aligned length (i.e., a multiple of 8 bits). Each MAC subheader may be placed immediately before the corresponding MAC SDU, MAC CE, or padding.

[0362] A MAC PDU (MAC protocol data unit) may consist of one or more MAC subPDUs. Each MAC subPDU may consist of one MAC subheader. A subPDU may consist of one MAC subheader and one MAC SDU (Service Data Unit). Each MAC subPDU may consist of one MAC subheader and one MAC CE. Each MAC subPDU may consist of one MAC subheader and padding. The MAC SDU is variable. Each MAC subheader may correspond to one MAC SDU, one MAC CE, or padding. A single MAC PDU may correspond to one transport block. .

[0363] The first MAC CE may be activation command A. The first MAC CE may be a MAC CE for activating or deactivating the TCI state for a PDSCH (a UE-specific PDSCH). The first MAC subheader may identify the MAC CE for activating / deactivating the TCI state for a PDSCH. For example, the first MAC subheader may be accompanied by a first LCID (Logical channel ID). For example, the value of the first LCID may be "TCI States Activation / Deactivation for UE-specific PDSCH".

[0364] Figure 9 shows an example of activation command A according to one aspect of this embodiment. The Serving cell ID field identifies the serving cell to which the first MAC CE is applied. The child may be indicated. The BWP ID field may indicate the DL BWP to which MAC CE applies as the code point of the DCI's 'bandwidth part indicator field'. The first MAC CE is When applied to a set of multiple serving cells, the BWP ID field may be ignored. i The field “T” may indicate the activation / deactivation status of the TCI state, accompanied by the TCI state ID i. i Setting the field of “ to 1 may indicate that the TCI state associated with TCI state ID i is activated. iSetting the field to 1 may indicate that the TCI state with TCI state ID i maps to one code point in the DCI's 'Transmission Configuration Indication field'. i When the field is set to 0, the TCI state associated with TCI state ID i is deactivated. You may also indicate that you will do so. i The setting of the field " to 1 may indicate that the TCI state with TCI state ID i does not map to one code point in the DCI's 'Transmission Configuration Indication field', where i is the TCI state ID (or TCI-StateID) This is also acceptable. A TCI state may be accompanied by a TCI state ID. Maximum number of “Activated TCI states” It may be 8. The field of CORESET pool ID is the first mapping, CORESET pool The CORESET ID (ControlResourceSetId) is set by the CORESET pool index. Alternatively, it may be shown to be unique. The first mapping is “the activated TCI state”. And, “T i The code point of the DCI 'Transmission Configuration Indication' set by the field may also be mapped to the field of the CORESET pool ID. Setting this to 1 means that the first MAC CE is applied to downlink transmissions scheduled by a CORESET with a CORESET pool ID (CORESET pool index) of value 1. This may indicate that the CORESET pool ID field is set to 0, which may indicate that the first MAC CE is applied to downlink transmissions scheduled by a CORESET with a CORESET pool ID (CORESET pool index) of value 0. If the coresetPoolIndex is not set, the CORESET pool ID in the first MAC CE is The field may be ignored.

[0365] The second MAC CE may be activation command B. The second MAC CE may be a MAC CE for activation or deactivation of the TCI state for a PDSCH (a UE-specific PDSCH). The MAC CE for activation / deactivation of the TCI state for a PDSCH may be identified by the second MAC subheader. For example, the second MAC subheader may be accompanied by a second LCID (Logical channel ID). The second LCID may be an eLCID. This is also acceptable. For example, the value of the second LCID may be "Enhanced TCI States Activation / Deactivation for UE-specific PDSCH".

[0366] Figure 10 shows an example of activation command B according to one aspect of this embodiment. i " of The field is the TCI status ID. i,2 You may also indicate whether an octet containing the character exists. For example, “C i If the field is set to 1, the TCI status ID i,2 An octet containing "C" may exist. For example, "C i If the field is set to 0, the TCI status ID i,2 An octet containing this may not exist. TCI state ID i,j The field is TC The TCI state may be identified by the TCI-StateId. i,jThis may represent the j-th TCI state indicated for the i-th code point in the DCI's 'Transmission configuration indication' field. TCI State ID i,2 is “C i "This may be optional based on the field indication. i may be the index of the code point in the DCI'Transmission configuration indication' field. j is 1 or 2 It's okay to have it.

[0367] The third MAC CE may be an activation command C. The third MAC CE may be a MAC CE for activation or deactivation of the unified TCI state. The MAC CE for activation / deactivation of the unified TCI state is identified by the third MAC subheader. This is also acceptable. For example, the third MAC subheader may include the third LCID (Logical channel ID). This is also acceptable. The third LCID may be an eLCID. For example, the value of the third LCID may be "Unified TCI States Activation / Deactivation MAC CE".

[0368] Figure 11 shows an example of an activation command C according to one aspect of this embodiment. The DL BWP ID field may indicate one downlink BWP to which MAC CE is applied as one code point in the DCI'bandwidth part indicator' field. The UL BWP ID field is Apply MAC CE to one uplink BWP, DCI's 'bandwidth part indicator' feel It may also be indicated as one of the chord points of "P". i The field may indicate whether each TCI code point has multiple TCI states or one TCI state. Example For example, “P i "If 1 is set in the field, the i-th TCI code point is DL TCI state It may include both states and UL TCI states. For example, “P i "When 0 is set in the field" In addition, the i-th TCI code point may include either a DL TCI state or a UL TCI state. The field is where the TCI state ID in the same octet is joint(both DL and UL) / DL, Alternatively, it may indicate whether it is for UL. For example, if the “D / U” field is set to 1, the TCI state ID in the same octet may be for DL / joint. For example, if the “D / U” field is set to 0, the TCI state ID in the same octet may be for UL. The “TCI state ID” field may indicate the TCI state identified by the TCI state ID (TCI-StateId). If the “D / U” field is set to 1, a 7-bit “TCI state ID” may be used. If the “D / U” field is set to 0, the most significant bit of the “TCI state ID” may be considered reserved. The remaining 6 bits may indicate the ID of the UL-TCIState (UL-TCIState-Id). The DL TCI state may be a TCI state that applies to some or all of PDSCH, PDCCH, and CSI-RS. The UL TCI state is a TCI state that applies to some or all of PUSCH, PUCCH, and SRS. This is also acceptable. A Joint TCI state may represent both a DL TCI state and a UL TCI state. A DLorJointTCIState may be either a DL TCI state or a Joint TCI state. A UL-TCIState may be a UL TCI state. A DL TCI state may be a TCI state for DL. A Joint TCI state may be a TCI state for both DL and UL. A UL TCI state may be a TCI state for UL. This may also be the case. A TCI code point is a DCI's Transmission configuration indication. It can also be a code point for a field. In MAC CE, the “R” field is confirmed It may also be a reserved bit. The reserved bit may be set to 0.

[0369] The fourth MAC CE may be activation command D. The fifth MAC CE may be activation command E. The fourth MAC CE may be activation or deactivation of the unified TCI state. A MAC CE may be for deactivation. For example, a fourth MAC CE may be for activation or deactivation of an enhanced unified TCI state. A fifth MAC CE may be for activation or deactivation of a unified TCI state. For example, a fifth MAC CE may be for activation or deactivation of an enhanced unified TCI state. It may also be a MAC CE for deactivation. By the fourth MAC subheader MAC CEs for activation / deactivation of the unified TCI state may be identified. Fifth MAC sub The header may identify the MAC CE for activating / deactivating the unified TCI state. For example, the fourth MAC subheader may include the fourth LCID (Logical channel ID). If the fifth MAC subheader is, it may also include a fifth LCID (Logical channel ID). The fourth LCID may be an eLCID. The fifth LCID may also be an eLCID. For example, if the value of the fourth LCID is "Enhanced unified TCI States Activation / Deactivation MAC CE 1", This is also acceptable. For example, the value of the fifth LCID may be "Enhanced unified TCI States Activation / Deactivation MAC CE 2".

[0370] Figure 12 shows an example of an activation command D according to one aspect of this embodiment. Serving The Cell ID (Serving cell ID) field identifies the serving cell to which the fourth MAC CE applies. The DL BWP ID field may indicate one downlink BWP to which the fourth MAC CE applies. Link BWP to one code point in the DCI's 'bandwidth part indicator' field and The UL BWP ID field may indicate one uplink BWP to which the fourth MAC CE applies. Link BWP is one code point in the DCI's 'bandwidth part indicator' field. You may give instructions by saying "P i The field “P” may indicate whether each TCI code point has multiple TCI states or one TCI state. For example, “P i"There is 1 in the field If set, the i-th TCI code point may include both DL TCI states and UL TCI states. For example, “P i "If the field is set to 0, the i-th TCI code point This may include either the DL TCI state or the UL TCI state. i The field of “ is each TCI code The dot point may indicate whether it is a joint (both DL and UL) / DL, or for UL. For example, “D / U i If the field is set to 1, the i-th TCI code point may be for DL / joint. For example, “D / U i "If the field is set to 0, the i-th TCI code point may be for UL." j The field “T” may indicate the activation / deactivation status of the TCI state, accompanied by the TCI state ID j. j " When the field is set to 1, the TCI state associated with TCI state ID j is activated. You may also indicate “T j The field of " being set to 1 means that the TCI state ID j is associated with the TCI The status is one code point in the DCI's 'Transmission Configuration Indication field'. You may also show that it maps to “T j Setting the field of “ to 0 may indicate that the TCI state associated with TCI state ID j is deactivated. jSetting the field to 1 may indicate that the TCI state with TCI state ID j does not map to one code point in the DCI's 'Transmission Configuration Indication field', where j is either a UL TCI state ID (UL-TCIState-Id) or a DL / Joint TCI state ID (DLorJoint-TCIState-Id). It may also be the case that the number of UL TCI state IDs is up to 64. The number of DL / Joint TCI state IDs is up to 128. j may be {0, ..., 63}. j may be {0, ..., 127 It may also be {0, ..., 191}. For example, the i-th TCI code point If it corresponds to the UL TCI state, then “T j The field “T” may indicate the activation / deactivation status of a TCI state with TCI state ID j-128. For example, if the i-th TCI code point corresponds to a DL TCI state or a Joint TCI state, then “T” j The field “T” may indicate the activation / deactivation status of a TCI state with TCI state ID j-64. For example, if the i-th TCI code point corresponds to a UL TCI state, “T” j The field being set to 1 means that the TCI with TCI status ID j-128 It may also indicate that a state is activated. For example, if the i-th TCI code point corresponds to the UL TCI state, “T j Setting the field " to 1 may indicate that the TCI state with TCI state ID j-128 is mapped to the i-th TCI code point. For example, if the i-th TCI code point corresponds to a DL TCI state or a Joint TCI state, then "T jSetting the field to 1 may indicate that a TCI state with TCI state ID j-64 is activated. For example, if the i-th TCI code point is a DL TCI state, or a Joint TCI state. When dealing with a state, “T j The field being set to 1 means that TCI status ID j-64 It may also indicate that the associated TCI state is mapped to the i-th TCI code point. The field of CORESET pool ID is the second mapping of CORESET pool ID (CORESET pool index This indicates that it is unique to the CORESET ID (ControlResourceSetId) set in (kus). That's good too. The second mapping is “Activated TCI state” and “T i "By field The DCI 'Transmission Configuration Indication' code point to be set may also be mapped to the value 1. Setting the CORESET pool ID field to 1 means the value 1 Scheduled by CORESET with CORESET pool ID (CORESET pool index) This may indicate that MAC CE is applied to downlink or uplink transmissions being scheduled. Setting the CORESET pool ID field to 0 may indicate that MAC CE is applied to downlink or uplink transmissions scheduled by a CORESET with a CORESET pool ID (CORESET pool index) of value 0. CORESET pool If the index (coresetPoolIndex) is not set, the CORESET pool in the fourth MAC CE will not work. The ID field can be ignored.

[0371] Figure 13 shows an example of an activation command E according to one aspect of this embodiment. The CORESET pool ID field may be reserved. i,j "feel The code may indicate whether each TCI code point has multiple TCI states or one TCI state. For example, “P i,j "If 1 is set in the field, the i-th TCI code Even if the j-th TCI state at a given point is two (for example, a DL TCI state and a UL TCI state) Good. For example, “P i,j "If the field is set to 0, the i-th TCI code point The j-th TCI state in this case may be a single state (for example, a DL TCI state or a UL TCI state). Yes. “D / U j The field “D / U” may indicate whether the TCI state ID in the same octet is joint(both DL and UL) / DL or UL. j The field of " is the same oct The TCI status ID in the set indicates whether it is for joint (both DL and UL) / DL or UL. It is also acceptable to use "D / U j "If a field is set to 1, in the same octet The TCI status ID may also be for DL / joint. For example, “D / U j "If the field is set to 0, the TCI state ID in the same octet may be for UL. i,j The field may indicate a TCI state identified by a DL / Joint TCI State ID (TCI-StateId) or a UL TCI State ID (UL-TCIState-Id). j "The field is set to 1" If so, a 7-bit "TCI state ID" is used. i,j " may be used. j If the field is set to 0, the "TCI state ID" i,jThe most significant bit of “ may be considered as reserved, and the remaining 6 bits may represent the UL-TCIState ID (UL TCI State ID, UL-TCIState-Id).

[0372] In Figure 13, j may correspond to the CORESET pool ID (CORESET pool index). For example, j=1 may correspond to CORESET pool ID (CORESET pool index)=0. For example, j=2 could correspond to CORESET pool ID (CORESET pool index)=1. For example, j=0 may correspond to CORESET pool ID (CORESET pool index)=0. j=1 may correspond to CORESET pool ID (CORESET pool index)=1. Whether j corresponds to CORESET pool ID (CORESET pool index) is determined by the "J" field. It may be determined by the following. For example, if the "J" field is set to 1, j may correspond to the CORESET pool ID (CORESET pool index). For example, if the "J" field is set to 0 If set, j corresponds to the index of the TCI state in a single code point. It's fine. “P i,j The field indicates whether each TCI code point of the DCI associated with the CORESET pool ID corresponding to j has multiple TCI states or only one TCI state. Good. For example, “P i,j If the field is set to 1, then the i-th TCI code point of the DCI associated with the CORESET pool ID corresponding to j corresponds to both the DL TCI state and the UL TCI state. That's also good. For example, “P i,j If the field is set to 0, the corresponding CORESET pool The i-th TCI code point of DCI associated with the ID corresponds to either the DL TCI state or the UL TCI state. This is also acceptable if the CORESET pool index (upper-level parameter coresetPoolIndex) is set. If not present, j does not need to correspond to a CORESET pool ID.

[0373] The activation command F may be MAC CE for TCI status indication for PDCCH. The transformation command F consists of a 5-bit serving cell ID, a 4-bit coreset ID, and a 7-bit TCI. It may consist of a state ID and a .

[0374] Activation command G may be MAC CE for TCI state indication for PDCCH. The activation command G may consist of a 5-bit serving cell ID, a 4-bit coreset ID, a 7-bit first TCI state ID, and a 7-bit second TCI state ID. If one or more coresets in a single BWP are set with different coreset pool index values, the activation command G may not be applied to one or more coresets. SFN is applied for PDCCH. If so, activation command G may be applied. SFN for PDCCH is applied. This may involve setting sfnSchemePdcch.

[0375] Terminal device 1 may receive an activation command. The activation command may be a collective term for activation command A, activation command B, activation command C, activation command D, activation command E, activation command F, and activation command G.

[0376] One or both of multiple uplink channels / signals (e.g., PUSCH, PUCCH, SRS) and multiple downlink channels / signals (e.g., PDSCH, PDCCH, CSI-RS) are in a single TCI state. Beam management is possible by applying a single TCI state to multiple channels / signals. In other words, by applying a single TCI state to multiple channels / signals, the efficiency of beam management is expected to be improved. However, in the case of Multi-TRP (Multiple Transmission and Reception Points), multiple channels / signals In contrast, applying a single TCI state makes it difficult to switch beams for each TRP. Thus, the challenge is that multiple channels / signals and one TCI state must be applied to each TRP. This may lead to efficient communication and efficient beam management. Furthermore, efficient beam management is expected by considering the time from when the beam is directed to when it is applied. As a means of solving this problem, the present invention may be used for beam management for physical channels by considering the switching times of some and all of the “configured TCI state,” “activated TCI state,” “directed TCI state,” and “applied TCI state.”

[0377] Figure 14 shows an example of TCI state management according to one aspect of this embodiment. A black circle may represent a single TCI state.

[0378] One or more TCI states 4100 may be set by higher-level parameters. For example, one or more UL TCI states (UL-TCIState) may be set by higher-level parameters for each uplink BWP (BWP-UplinkDedicated). For example, one or more DL / Joint TCI states (DLorJointTCIState) may be set by higher-level parameters for each PDSCH configuration (PDSCH-Config). It is also possible that one TCI state may be associated with one TCI state ID. For example, one UL TCI state A state may be associated with a single UL TCI state ID (TCI-UL-State-Id, UL-TCIState-Id). For example, a single DL / Joint TCI state (TCI-state) may be associated with a single TCI state ID (TCI-stateId). i. One or more TCI states set by the higher-level parameters may be the set TCI states 4100.

[0379] One or more TCI states 4200 may be activated by MAC CE (e.g., activation command). The first PDSCH may transmit the first transport block. A sport block may be a single MAC PDU. A single MAC PDU may contain an activation command, or a MAC CE referred to as an activation command. For example, an activation command is , activation command D, or activation command E. One or more TCI states, and one or both of one or more “pairs of TCI states”, one or more code points They may be mapped to points. For example, an activation command may map one or more TCI states, and one or both of a “pair of TCI states,” to one or more code points. Each TCI state, or each pair of TCI states, may be mapped to one code point. It may be done that way. For example, by an activation command, each TCI state, or each pair of TCI states, may be mapped to a single code point. The mapped code points may also be code points in the TCI field. The code point to which a TCI state, or a pair of TCI states, is mapped may also be the code point of the TCI field in DCI format 1_1 or DCI format 1_2. i. The code point to which a TCI state, or a pair of TCI states, is mapped may also be the code point of the TCI field in DCI. The TCI state activated by MAC CE is, The activated TCI state may be 4200. The TCI state mapped to the code point of the TCI field may be the activated TCI state 4200.

[0380] If the CORESET pool index (coresetPoolIndex) is not set in one or more CORESETs (ControlResourceSets), the activation command E may be used. When the coresetPoolIndex is set in one or more CORESETs (ControlResourceSets), activation command D or activation command E may be used. For example, when First CORESETs and Second CORESETs are provided, activation command D or activation command E may be used. For example, in single-DCI mode, activation command E may be used. For example, in multi-DCI mode, activation command D may be used. For example, in both single-DCI mode and multi-DCI mode, activation command E may be used.

[0381] One or more TCI states 4300 may be indicated by a first DCI. The first DCI may be DCI format 1_1 or DCI format 1_2. The first DCI may include a TCI (Transmission configuration indication) field. The TCI field is 1 Alternatively, multiple (e.g., two or four) TCI states may be indicated. For example, one value in the TCI field may correspond to one code point in the TCI field. The TCI state indicated by the first DCI format may be indicated TCI state 4300. Indicated TCI state 4300 may be some or all of the UL TCI state, DL TCI state, and Joint TCI state. The UL TCI state may be the TCI state for PUSCH, PUCCH, and SRS. The DL TCI state may be the TCI state for PDSCH, PDCCH, and CSI-RS. The Joint TCI state is the TCI state for PUSCH, PUCCH, SRS, PDSCH, PDCCH, and CSI-RS. It's fine to act that way.

[0382] One or more TCI states 4300 may be indicated by a first DCI and a second DCI. Each of the first and second DCIs may be DCI format 1_1 or DCI format 1_2. The first DCI, or the PDCCH in which the first DCI is located, may correspond to or be associated with CORESET pool index 0. The second DCI, or the PDCCH in which the second DCI is located, may correspond to or be associated with CORESET pool index 1. Each of the DCIs includes a TCI (Transmission Configuration Indication) field. This is also acceptable. The TCI state indicated by the first DCI and the second DCI may be the indicated TCI state 4300. For example, the first TCI state 4400 among the indicated TCI states 4300 is the first DCI It may be indicated by a second TCI state 4401 among the indicated TCI states 4300, which may be indicated by a second DCI.

For example, the number of TCI states 4300 to be indicated is: The first pair consists of the first UL TCI state and the first DL TCI state, and the second UL TCI state and the second DL T It may also be a second pair with the CI state. The first pair may also be related to the first TRP. The second pair may also be related to the second TRP.

For example, the number of TCI states 4300 to be indicated is: There may be a first DL / UL / Joint TCI state and a second DL / UL / Joint TCI state. The first DL / UL / Joint may be associated with a first TRP, and the second DL / UL / Joint TCI state may be associated with a second TRP.

[0393] Figure 16 shows an example of PUCCH transmission according to one aspect of this embodiment.

[0394] Figure 16 may be an example in Single-DCI mode. Terminal device 1 may receive PDCCH6000. Terminal device 1 may receive PDCCH6000 in CORESET6300. In CORESET6300 corresponding to PDCCH6000, the CORESET pool index (upper layer parameter CORESETPoolIndex) may not be provided. For CORESET6300 corresponding to PDCCH6000, or for PDCCH6000, the indicated TCI state 4300 may be applied. For example, in CORESET6300 In contrast, or with respect to PDCCH6000, one of the first TCI state 4400 and the second TCI state 4401 Or both may apply. For example, one upper-level parameter may be the first instruction, the second instruction. One of the first, second, third, and fourth instructions may be provided or given. For example, one upper layer parameter may provide or give one of the first, second, third, and fourth instructions for PDCCH6000. One upper layer parameter is This may be configured or provided for CORESET6300.

[0395] If the first instruction is given, the first TCI state 4400 is CORESET6300 or PDCCH6000 If a second instruction is given, a second TCI state 4401 may be applied to CORESET6300 or PDCCH6000. If a third or fourth instruction is given In this case, both the first TCI state 4400 and the second TCI state 4401 may be applied to CORESET 6300 or PDCCH 6000.

[0396] Terminal device 1 may receive PDSCH6100. DCI6400, located at PDCCH6000, may receive PDSCH6100, or schedule reception of PDSCH6100. Indicated TCI state 4300 This may also be applied to PDSCH6100. For example, for PDSCH6100, the first TCI state 4400 and One or both of the second TCI states 4401 may apply. For example, DCI6400, or one field in DCI6400, may provide or give any of the first, second, third, and fourth instructions. For example, DCI6400, or one field in DCI6400, may provide or give any of the first, second, third, and fourth instructions for PDSCH6100.

[0397] If the first instruction is given, the first TCI state 4400 may be applied to the PDSCH6100. If the second instruction is given, the second TCI state 4401 may be applied to the PDSCH6100. If the third or fourth instruction is given, both the first TCI state 4400 and the second TCI state 4401 may be applied to the PDSCH6100.

[0398] Terminal device 1 may transmit PUCCH6200. Terminal device 1 may transmit or report UCI6500. DCI6400 will transmit PUCCH6200 or schedule the transmission of PUCCH6200. It may be a ring. UCI6500 may be included in PUCCH6200 and may be placed there. UCI6500 may be HARQ-ACK or HARQ-ACK information. For example, UCI6500 may be PDSCH6100 This may also be HARQ-ACK information for the transport block transmitted by the PDSCH6100, or for the detection of the DCI6400 that schedules the PDSCH6100. PUCCH6200 corresponds to PUCCH Resource 6600 may be determined or indicated by DCI6400.

[0399] The indicated TCI state 4300 may be applied to PUCCH6200. For example, to PUCCH6200 Then, either or both of the first TCI state 4400 and the second TCI state 4401 may be applied. For example, PUCCH resource 6600, or the higher-level parameter in PUCCH resource 6600, may provide or give any of the first, second, third, and fourth instructions. For example, PUCCH resource 6600, or the higher-level parameter TCI-selectionForPUCCH in PUCCH resource 6600, may provide or give any of the first, second, third, and fourth instructions for PUCCH6200. UL-TCIState, or If DLorJointTCIState is set (provided), it is not expected that the higher-level parameter TCI-selectionForPUCCH will not be set (provided). If PUCCH-SpatialRelationInfo is set (provided), it is not expected that the higher-level parameter TCI-selectionForPUCCH will be set (provided).

[0400] If the first instruction is given, the first TCI state 4400 may be applied to PUCCH6200. If the second instruction is given, the second TCI state 4401 may be applied to PUCCH6200. If the third or fourth instruction is given, both the first TCI state 4400 and the second TCI state 4401 may be applied to PUCCH6200. If a first instruction is given, one spatial setting may be determined based on the first TCI state 4400. If a second instruction is given, one spatial setting may be determined based on the second TCI state 4401. The PUCCH resource 6600 may correspond to one spatial setting and one space Interval settings may be included. If a third instruction is given, the first TCI state 4400 is the first space The setting 6700 corresponds to the second TCI state 4401, and the second spatial setting 6701 may also correspond to the fourth If instructions are given, the first TCI state 4400 may correspond to the second spatial setting 6701, and the second TCI state 4401 may correspond to the first spatial setting 6700. For example, the PUCCH resource 6600 is the first This may correspond to spatial setting 6700 and a second spatial setting 6701, or it may include the first spatial setting 6700 and the second spatial setting 6701.

[0401] If TCI-selectionForPUCCH is not provided for PUCCH resource 6600, then PUCCH6200, Alternatively, the spatial settings for PUCCH6200 transmission may be the default spatial settings. PUCCH resource 6600 is a common PUCCH resource (PUCCH resource provided by pucch-ResourceCommon). If it is (-), the spatial setting for PUCCH6200, or PUCCH6200 transmission, is default. Spatial settings are also acceptable. That is, TCI-selectionForPUCCH does not need to be set for common PUCCH resources, nor is it expected that it will be set. Also, PDCCH6000 If the number of OFDM symbols (offset) from the last OFDM symbol to the first OFDM symbol of PUCCH6200 is less than or equal to the threshold, then the spatial setting for PUCCH6200, or PUCCH6200 transmission, is The default spatial setting may also be used. Furthermore, if the number of OFDM symbols (offset) from the last OFDM symbol of PDSCH6100 to the first OFDM symbol of PUCCH6200 is less than or equal to a threshold, the spatial setting for PUCCH6200, or for PUCCH6200 transmission, may be the default spatial setting.

[0402] The default spatial settings may be determined based on the indicated TCI state 4300. For example, The default spatial setting may be the same as the spatial setting for PDCCH6000 or PDCCH6000 reception. For example, the default spatial setting may be determined based on the first TCI state 4400 or the second TCI state 4401.

[0403] Figure 16 may be an example in Multi-DCI mode. Terminal device 1 receives PDCCH6001. Terminal device 1 may receive PDCCH6001 in CORESET6301. Terminal device 1 may receive PDCCH6000 in CORESET6300 and PDCCH6001 in CORESET6301. CORESET6300 may be different from CORESET6301. CORESET pool index 0 (a CORESET pool index set to 0) may be provided for CORESET6300. CORESET pool index 1 (a CORESET pool index set to 1) may be provided for CORESET6301. For CORESET6300 or PDCCH6000, the indicated TCI state 4300 may be applied. For CORESET6301 or PDCCH6001, the indicated TCI State 4300 may be applied. For example, for CORESET6300 or PDCCH6000, either the first TCI state 4400 or the second TCI state 4401 may be applied. For example, CORESET6301, Alternatively, either the first TCI state 4400 or the second TCI state 4401 may be applied to PDCCH6001. That's fine.

[0404] The first TCI state 4400 may correspond to or be associated with CORESET pool index 0. The second TCI state 4401 may correspond to or be associated with CORESET pool index 1. For example, the first TCI state 4400 is determined by MAC CE corresponding to CORESET pool index 0. It may be included in the TCI state that is activated. For example, the second TCI state 4401 is CORESET pool It may be included in the TCI state activated by MAC CE corresponding to pool index 1. If CORESET pool index 0 is provided for CORESET6300, the first TCI state 4400 may be applied to PDCCH6000 in CORESET6300. If CORESET pool index 1 is provided for CORESET6301, the second TCI state 4401 may be applied to PDCCH6001 in CORESET6301.

[0405] Terminal device 1 may receive PDSCH6100 and PDSCH6101. DCI6400 located on PDCCH6000 may schedule reception of PDSCH6100 or PDSCH6100. DCI6401 located on PDCCH6001 may schedule reception of PDSCH6101 or PDSCH6101. Good. The indicated TCI state 4300 may be applied to PDSCH6100 and PDSCH6101. For example, the first TCI state 4400 may be applied to PDSCH6100. For example, the first TCI state 4401 may be applied to PDSCH6101.

[0406] If CORESET pool index 0 is provided for CORESET6300 corresponding to PDCCH6000, and PDSCH6100 is scheduled by DCI6400 located on PDCCH6000. In this case, the first TCI state 4400 may be applied to PDSCH6100. If CORESET pool index 1 is provided for CORESET6301 corresponding to PDCCH6001, and is placed in PDCCH6001 If PDSCH6101 is scheduled by DCI6401, a second TCI state 4401 may be applied to PDSCH6101.

[0407] Terminal device 1 may transmit PUCCH6200 and PUCCH6201. Terminal device 1 may transmit or report UCI6500 and UCI6501. DCI6400 may schedule the transmission of PUCCH6200 or PUCCH6200. DCI6401 may schedule the transmission of PUCCH6201 or PUCCH6201. UCI6500 may be included in or placed within PUCCH6200. UCI6501 may be included in or placed within PUCCH6201. Each of UCI6500 and UCI6501 may be HARQ-ACK or HARQ-ACK information. For example, UCI6500 may be HARQ-ACK information for the detection of PDSCH6100, the transport block transmitted by PDSCH6100, or DCI6400 scheduling PDSCH6100. For example, UCI6501 may be HARQ-ACK information for the detection of PDSCH6101, the transport block transmitted by PDSCH6101, or DCI6400 scheduling PDSCH6101. The detection of the assigning DCI6401 may also be HARQ-ACK information. The PUCCH resource 6600 corresponding to PUCCH6200 may be determined or indicated by DCI6400. The PUCCH resource 6601 corresponding to PUCCH6201 may be determined or indicated by DCI6401. .

[0408] The first TCI state 4400 may correspond to or be associated with CORESET pool index 0. The second TCI state 4401 may correspond to or be associated with CORESET pool index 1. The first TCI state 4400 may correspond to the first spatial setting 6700. The second TCI state 4401 may correspond to the second spatial setting 6701. The first spatial setting 6700 is CORESET pool index It may also correspond to ks0. The second spatial setting 6701 corresponds to CORESET pool index 1. That's fine.

[0409] Means 1 and 2 may be used to determine the spatial settings applicable to PUCCH6200 and PUCCH6201, respectively.

[0410] In method 1, TCI-selectionForPUCCH may be set (provided) for PUCCH resource 6600 and PUCCH resource 6601, respectively. If TCI-selectionForPUCCH for PUCCH resource 6600 gives the first instruction, PUCCH resource 6600 is associated with CORESET pool index 0. If TCI-selectionForPUCCH for PUCCH resource 6600 gives the second instruction, PUCCH resource 6600 may be associated with CORESET pool index 1. If TCI-selectionForPUCCH for PUCCH resource 6600 gives the third or fourth instruction, PUCCH resource 6600 may be associated with CORESET pool index 0 and CORESET pool index 1. If TCI-selectionForPUCCH for PUCCH resource 6601 gives the first instruction, PUCCH resource 6601 may be associated with CORESET pool index 0. If TCI-selectionForPUCCH for PUCCH resource 6601 gives the second instruction, PUCCH resource 6601 may be associated with CORESET pool index 1. If TCI-selectionForPUCCH for PUCCH resource 6601 gives a third or fourth instruction, PUCCH resource 6601 may be associated with CORESET pool index 0 and CORESET pool index 1.

[0411] In the first case, the first spatial setting 6700 may be used for PUCCH6200. In case 1, the DCI6400 that schedules the PUCCH6200 corresponds to the PDCCH6000 where it is located. The CORESET6300 may be associated with CORESET pool index 0, and the TCI-selectionForPUCCH for PUCCH resource 6600 indicated by DCI6400 may give a second instruction. That is, if CORESET6300 is associated with CORESET pool index 0, the first spatial setting 6700 may be used for PUCCH6200. In the second case, for PUCCH6201 A second spatial setting 6701 may be used. In the second case, PUCCH6201 is scheduled The CORESET6301 corresponding to the PDCCH6001 where the DCI6401 is located may be associated with CORESET pool index 1, and the TCI-selectionForPUCCH for the PUCCH resource 6601 indicated by DCI6401 may give the first instruction. That is, if CORESET6301 is associated with CORESET pool index 1, a second spatial setting 6701 may be used for PUCCH6201. For example, when DCI6400 schedules PUCCH6200 (transmission of PUCCH6200) Even if TCI-selectionForPUCCH in PUCCH resource 6600 for PUCCH6200 is ignored That's fine. For example, if DCI6401 schedules PUCCH6201 (transmitting PUCCH6201), then TCI-selectionForPUCCH in PUCCH resource 6601 for PUCCH6201 may be ignored.

[0412] In method 2, it is not necessary to expect that TCI-selectionForPUCCH will be set (provided) for each of the PUCCH resources 6600 and 6601. That is, TCI-selectionForPUCCH will not be set (provided) for each of the PUCCH resources 6600 and 6601. This may also be the case. If PUCCH resource 6600 is directed by DCI6400, then PUCCH resource 6600 It is not expected that TCI-selectionForPUCCH will be set (provided) for PUCCH resource 6601. If PUCCH resource 6601 is indicated by DCI6401, it is not expected that TCI-selectionForPUCCH will be set (provided) for PUCCH resource 6601.

[0413] If CORESET6300 is associated with CORESET pool index 0, the first spatial setting 6700 may be used for PUCCH6200. If CORESET6301 is associated with CORESET pool index 1, In that case, a second spatial setting 6701 may be used for PUCCH6201.

[0414] Terminal device 1 may receive PDCCH6002. Terminal device 1 may receive PDCCH6002 in CORESET6302. For CORESET6302, CORESET pool index 0 (a CORESET pool index set to 0) or CORESET pool index 1 (a CORESET pool index set to 1) may be provided. For CORESET6302 or PDCCH6002, the indicated TCI state 4300 may be applied. For example, CORESET6302 or PDCC For H6002, either the first TCI state 4400 or the second TCI state 4401 may be applied.

[0415] If CORESET pool index 0 is provided for CORESET6302, the first TCI state 4400 may be applied to CORESET6302 or PDCCH6002 in CORESET6302. If CORESET pool index 1 is provided for CORESET6302, the second TCI state 4401 may be applied to CORESET6302 or PDCCH6002 in CORESET6302.

[0416] Terminal device 1 may receive PDSCH6102. PDSCH6102 may be an SPS PDSCH. PDCCH6002 may be a DL SPS assignment PDCCH. For example, PDCCH6002 may be validated for SPS PDSCH6102. For example, the CRC of DCI6402 in PDCCH6002 may be scrambled by CS-RNTI. For example, DCI6402 is set A link assignment may be provided. DCI6402, located on PDCCH6002, may activate PDSCH6102, or the reception of PDSCH6102. Reception of PDSCH6102 corresponds It may be assumed that there is no PDCCH. The indicated TCI state 4300 applies to PDSCH6102. This is also acceptable. For example, for PDSCH6102, the first TCI state 4400 or the second TCI state 4401 This may also apply.

[0417] If CORESET pool index 0 is provided for CORESET6302, the first TCI state 4400 may be applied to PDSCH6102. If CORESET pool index 1 is provided for CORESET6302, the second TCI state 4401 may be applied to PDSCH6102.

[0418] Terminal device 1 may transmit PUCCH6202. Terminal device 1 may transmit or report UCI6502. DCI6402 activates PUCCH6202 or PUCCH6202 transmission. This is also acceptable. UCI6502 may be included in or located within PUCCH6202. UCI6502 may be HARQ-ACK or HARQ-ACK information. For example, UCI6502 may be the reception of SPS PDSCH6102. or HARQ-ACK information for the transport block transmitted by PDSCH6102 That's good too. UCI6502 is HARQ-ACK information corresponding to PDSCH6102 reception without a corresponding PDCCH. That's fine.

[0419] The PUCCH resource 6602 corresponding to PUCCH6202 may be determined based on higher-layer parameters. These higher-layer parameters may be SPS-PUCCH-AN-List or n1PUCCH-AN. For example, if SPS-PUCCH-AN-List is not provided, PUCCH resource 6602 for PUCCH6202 This may be provided by n1PUCCH-AN. The upper-layer parameter may provide a single PUCCH resource ID (PUCCHResourceId).

[0420] Means 3a, 3b, and 4 may be used to determine the spatial configuration applied to PUCCH6202.

[0421] In means 3a and means 3b, TCI-selectionForPUCCH may be set (provided) for the PUCCH resource 6602. If TCI-selectionForPUCCH for the PUCCH resource 6602 gives a first instruction, the PUCCH resource 6602 may be associated with CORESET pool index 0. If TCI-selectionForPUCCH for the PUCCH resource 6602 gives a second instruction, the PUCCH resource 6602 may be associated with CORESET pool index 1. If TCI-selectionForPUCCH for the PUCCH resource 6602 gives a third or fourth instruction, the PUCCH resource 6602 may be associated with CORESET pool index 0 and CORESET pool index 1.

[0422] In means 3a, if CORESET 6302 is associated with CORESET pool index 0 and TCI-selectionForPUCCH for PUCCH resource 6602 gives a first instruction, then a first spatial setting 6700 may be used for PUCCH 6202. If CORESET 6302 is associated with CORESET pool index 0 and TCI-selectionForPUCCH for PUCCH resource 6602 gives a second instruction If an indication is given, a second spatial setting 6701 may be used for PUCCH6202. If CORESET6302 is associated with CORESET pool index 1, and TCI-selectionForPUCCH for PUCCH resource 6602 gives a first indication, then a first spatial setting 6700 for PUCCH6202 This may be used. If CORESET6302 is associated with CORESET pool index 1, If TCI-selectionForPUCCH for PUCCH resource 6602 gives a second instruction, a second spatial setting 6701 may be used for PUCCH 6202. That is, if TCI-selectionForPUCCH gives a first instruction, a first spatial setting 6700 may be used for PUCCH 6202. That is, if TCI-selectionForPUCCH gives a second instruction, a second spatial setting 6701 may be used for PUCCH6202. For example, if TCI-selectionForPUCCH is provided for PUCCH resource 6602, the CORESET pool index of CORESET6302 may be ignored.

[0423] In means 3b, if CORESET 6302 is associated with CORESET pool index 0 and TCI-selectionForPUCCH for PUCCH resource 6602 gives a first instruction, then a first spatial setting 6700 may be used for PUCCH 6202. If CORESET 6302 is associated with CORESET pool index 0 and TCI-selectionForPUCCH for PUCCH resource 6602 gives a second instruction If an indication is given, the first spatial setting 6700 may be used for PUCCH6202. If CORESET6302 is associated with CORESET pool index 1, and TCI-selectionForPUCCH for PUCCH resource 6602 gives the first indication, the second spatial setting 6701 may be used for PUCCH6202. This may be used. If CORESET6302 is associated with CORESET pool index 1, If TCI-selectionForPUCCH for PUCCH resource 6602 gives a second instruction, a second spatial setting 6701 may be used for PUCCH 6202. That is, CORESET 6302 is CORESET If associated with pool index 0, the first spatial setting 6700 may be used for PUCCH6202. That is, if CORESET6302 is associated with CORESET pool index 1, the second spatial setting 6701 may be used for PUCCH6202. For example, if PUCCH resource 6602 The TCI-selectionForPUCCH parameter can be ignored.

[0424] In method 4, TCI-selectionForPUCCH is set (provided) to the PUCCH resource 6602. This is not expected.
