The downlink physical signal may be a physical signal used in a downlink component carrier. The downlink physical signal may be transmitted by a base station device 3. The downlink physical signal may be transmitted by a terminal device 1. In a wireless communication system according to one aspect of this embodiment, at least some or all of the following downlink physical signals may be used. ·Synchronization signal (SS) ·DL DMRS(DownLink DeModulation Reference Signal) ·CSI-RS(Channel State Information-Reference Signal) ·DL PTRS(DownLink Phase Tracking Reference Signal)

[0158] The synchronization signal may be used at least for synchronization in the frequency domain and / or the time domain of the downlink by the terminal device 1. The synchronization signal is a general term for a PSS (Primary Synchronization Signal) and an SSS (Secondary Synchronization Signal).

[0159] FIG. 7 is a diagram showing an example of the configuration of an SS / PBCH block according to one aspect of this embodiment. In FIG. 7, the horizontal axis is the time axis (OFDM symbol index l sym ), where the vertical axis represents the frequency domain. The diagonally shaded blocks represent sets of resource elements for PSS. The grid-lined blocks represent sets of resource elements for SSS. The horizontally shaded blocks represent sets of resource elements for PBCH and DMRS for the PBCH (DMRS related to the PBCH, DMRS included in the PBCH, and DMRS corresponding to the PBCH).

[0160] As shown in FIG. 7, the SS / PBCH block includes a PSS, SSS, and PBCH. The SS / PBCH block includes four consecutive OFDM symbols. The SS / PBCH block includes 240 subcarriers. The PSS is allocated to the 57th to 183rd subcarriers in the first OFDM symbol. The SSS is allocated to the 57th to 183rd subcarriers in the third OFDM symbol. The 1st to 56th subcarriers in the first OFDM symbol may be set to zero. The 184th to 240th subcarriers in the first OFDM symbol may be set to zero. The 49th to 56th subcarriers in the third OFDM symbol may be set to zero. The 184th to 192nd subcarriers in the third OFDM symbol may be set to zero. The PBCH is allocated to the 1st to 240th subcarriers in the second OFDM symbol, which are subcarriers where the DMRS for the PBCH is not allocated. The PBCH is allocated to the 1st to 48th subcarriers of the third OFDM symbol, and to subcarriers where DMRS for the PBCH is not allocated. The PBCH is allocated to the 193rd to 240th subcarriers of the third OFDM symbol, and to subcarriers where DMRS for the PBCH is not allocated. The PBCH is allocated to the 1st to 240th subcarriers of the fourth OFDM symbol, and to subcarriers where DMRS for the PBCH is not allocated.

[0161] The antenna ports for the PSS, SSS, PBCH, and DMRS for the PBCH may be the same.

[0162] The PBCH on which the PBCH symbol is transmitted at a certain antenna port may be estimated by the DMRS for the PBCH that is placed in the slot to which the PBCH is mapped and is included in the SS / PBCH block to which the PBCH belongs.

[0163] DL DMRS is a general term for DMRS for PBCH, DMRS for PDSCH, and DMRS for PDCCH.

[0164] The set of antenna ports for DMRSs for a PDSCH (DMRSs associated with a PDSCH, DMRSs included in a PDSCH, and DMRSs corresponding to a PDSCH) may be determined based on the set of antenna ports for the PDSCH, i.e., the set of antenna ports for DMRSs for a PDSCH may be the same as the set of antenna ports for the PDSCH.

[0165] The transmission of the PDSCH and the transmission of the DMRS for the PDSCH may be indicated (or scheduled) by one DCI format. The PDSCH and the DMRS for the PDSCH may be collectively referred to as the PDSCH. Transmitting the PDSCH may also mean transmitting the PDSCH and the DMRS for the PDSCH.

[0166] A PDSCH may be estimated from a DMRS for the PDSCH. That is, a propagation path of a PDSCH may be estimated from the DMRS for the PDSCH. If a set of resource elements carrying a certain PDSCH symbol and a set of resource elements carrying a DMRS for the certain PDSCH symbol are included in the same precoding resource group (PRG), the PDSCH carrying the PDSCH symbol for a certain antenna port may be estimated by the DMRS for the PDSCH.

[0167] The antenna port of the DMRS for the PDCCH (DMRS related to the PDCCH, DMRS included in the PDCCH, DMRS corresponding to the PDCCH) may be the same as the antenna port for the PDCCH.

[0168] A PDCCH may be estimated from a DMRS for the PDCCH. That is, a propagation path of a PDCCH may be estimated from a DMRS for the PDCCH. If the same precoder is applied (or assumed to be applied) to a set of resource elements on which a certain PDCCH symbol is transmitted and a set of resource elements on which a DMRS symbol for the PDCCH is transmitted, the PDCCH on which a certain antenna port transmits a PDCCH symbol may be estimated by the DMRS for the PDCCH.

[0169] The BCH (Broadcast CHannel), UL-SCH (Uplink-Shared CHannel), and DL-SCH (Downlink-Shared CHannel) are transport channels. Channels used in the MAC layer are called transport channels. The unit of transport channels used in the MAC layer is also called a transport block (TB) or MAC PDU (Protocol Data Unit). In the MAC layer, HARQ (Hybrid Automatic Repeat reQuest) control is performed for each transport block. A transport block is a unit of data that the MAC layer delivers to the physical layer. In the physical layer, a transport block is mapped to a codeword, and modulation processing is performed for each codeword.

For example, the BCCH is a channel of the RRC layer used for transmitting MIB or system information. The CCCH (Common Control CHannel) may be used for transmitting an RRC message common to a plurality of terminal devices 1. Here, the CCCH may be used, for example, for a terminal device 1 that is not RRC connected. The DCCH (Dedicated Control CHannel) may be used at least for transmitting an RRC message dedicated to the terminal device 1. Here, the DCCH may be used, for example, for a terminal device 1 that is RRC connected.

[0172] An RRC message includes one or more RRC parameters (information elements). For example, an RRC message may include an MIB. An RRC message may also include system information. An RRC message may also include a message corresponding to a CCCH. An RRC message including a message corresponding to a DCCH is also called a dedicated RRC message.

[0173] The BCCH in the logical channel may be mapped to the BCH or DL-SCH in the transport channel, the CCCH in the logical channel may be mapped to the DL-SCH or UL-SCH in the transport channel, and the DCCH in the logical channel may be mapped to the DL-SCH or UL-SCH in the transport channel.

[0174] The UL-SCH in the transport channel may be mapped to the PUSCH in the physical channel, the DL-SCH in the transport channel may be mapped to the PDSCH in the physical channel, and the BCH in the transport channel may be mapped to the PBCH in the physical channel.

[0175] The upper layer parameters (upper layer parameters) are parameters included in an RRC message or a MAC CE (Medium Access Control Control Element). That is, the upper layer parameters are a collective term for the parameters included in the MIB, system information, a message corresponding to the CCCH, a message corresponding to the DCCH, and the MAC CE. The parameters included in the MAC CE are transmitted by a MAC CE (Control Element) command.

[0178] The sequence of PSSs is based at least on a physical cell ID. The sequence of SSSs is based at least on a physical cell ID.

[0179] The SS / PBCH block candidates indicate resources on which transmission of the SS / PBCH block is permitted (possibly, reserved, configured, defined, possible).

[0180] The set of SS / PBCH block candidates in a half radio frame is also called the SS burst set. The SS burst set is also called the transmission window, SS transmission window, or DRS (Discovery Reference Signal) transmission window. The SS burst set is a general term that includes at least the first SS burst set and the second SS burst set.

[0181] The base station device 3 transmits SS / PBCH blocks of one or more indexes at a predetermined period. The terminal device 1 may detect at least one of the SS / PBCH blocks of the one or more indexes and attempt to decode the PBCH included in the SS / PBCH block.

[0182] Random access is a procedure that includes at least some or all of message 1, message 2, message 3, and message 4.

[0183] Message 1 is a procedure for transmitting a PRACH by a terminal device 1. The terminal device 1 transmits a PRACH in one PRACH opportunity selected from one or more PRACH opportunities based at least on an index of an SS / PBCH block candidate detected based on a cell search. Each PRACH opportunity is defined based at least on resources in the time domain and the frequency domain.

[0184] The terminal device 1 transmits one random access preamble selected from among the PRACH opportunities corresponding to the index of the SS / PBCH block candidate from which the SS / PBCH block is detected.

[0185] Message 2 is a procedure in which the terminal device 1 attempts to detect DCI format 1_0 with a CRC (Cyclic Redundancy Check) scrambled with an RA-RNTI (Random Access - Radio Network Temporary Identifier). The terminal device 1 attempts to detect a PDCCH including this DCI format in a control resource set given based on an MIB included in a PBCH included in an SS / PBCH block detected based on a cell search and in resources indicated based on the setting of a search space set. Message 2 is also referred to as a random access response.

[0186] Message 3 is a procedure for transmitting a PUSCH scheduled by a random access response grant included in DCI format 1_0 detected by the procedure for message 2. Here, the random access response grant is indicated by a MAC CE included in a PDSCH scheduled by DCI format 1_0.

[0187] The PUSCH scheduled based on the random access response grant is either a message 3 PUSCH or a PUSCH. The message 3 PUSCH includes a contention resolution identifier (MAC CE). The contention resolution identifier (MAC CE) includes the contention resolution ID.

[0188] Message 3 PUSCH retransmissions are scheduled with DCI format 0_0 with CRC scrambled based on TC-RNTI (Temporary Cell - Radio Network Temporary Identifier).

[0189] Message 4 is a procedure for attempting to detect DCI format 1_0 with a CRC scrambled based on either a C-RNTI (Cell-Radio Network Temporary Identifier) ​​or a TC-RNTI. The terminal device 1 receives a PDSCH scheduled based on the DCI format 1_0. The PDSCH may include a collision resolution ID.

[0190] Data communication is a general term for downlink communication and uplink communication.

[0191] In data communication, the terminal device 1 attempts to detect the PDCCH in resources specified based on the control resource set and the search space set (monitors the PDCCH).

[0192] A control resource set is a set of resources consisting of a predetermined number of resource blocks and a predetermined number of OFDM symbols. In the frequency domain, a control resource set may be composed of contiguous resources (non-interleaved mapping) or distributed resources (interleaver mapping).

[0193] A set of resource blocks constituting the control resource set may be indicated by a higher layer parameter, and the number of OFDM symbols constituting the control resource set may be indicated by a higher layer parameter.

[0194] The terminal device 1 attempts to detect a PDCCH in a search space set. Here, attempting to detect a PDCCH in a search space set may be attempting to detect a PDCCH candidate in the search space set, may be attempting to detect a DCI format in the search space set, may be attempting to detect a PDCCH in a control resource set, may be attempting to detect a PDCCH candidate in the control resource set, or may be attempting to detect a DCI format in the control resource set.

[0195] The search space set is defined as a set of PDCCH candidates. The search space set may be a Common Search Space (CSS) set or a UE-specific Search Space (USS) set. The terminal device 1 attempts to detect PDCCH candidates in some or all 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.

[0196] The Type 0 PDCCH common search space set may be used as the common search space set with index 0. The Type 0 PDCCH common search space set may be the common search space set with index 0.

[0197] The CSS set is a collective term for 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, and a Type 3 PDCCH common search space set. The USS set is also called a UE-specific PDCCH search space set.

[0198] A search space set is associated with (contained in, corresponds to) a control resource set. The index of the control resource set associated with the search space set may be indicated by a higher layer parameter.

[0199] For a given search area set, some or all of 6A to 6C may be indicated by at least higher layer parameters. 6A) PDCCH monitoring periodicity 6B) PDCCH monitoring pattern within a slot 6C) PDCCH monitoring offset

[0200] A monitoring occasion for a search space set may correspond to an OFDM symbol in which a first OFDM symbol of a control resource set associated with the search space set is located. A monitoring occasion for a search space set may correspond to resources of a control resource set starting from a first OFDM symbol of the control resource set associated with the search space set. The monitoring occasion for the search space set is determined based on at least some or all of a PDCCH monitoring interval, a PDCCH monitoring pattern within a slot, and a PDCCH monitoring offset.

[0201] 8 is a diagram illustrating an example of a monitoring opportunity for a search area set according to one aspect of the present embodiment. In FIG. 8, search area set 91 and search area set 92 are set in primary cell 301, search area set 93 is set in secondary cell 302, and search area set 94 is set in secondary cell 303.

[0202] In Figure 8, blocks indicated by grid lines represent search area set 91, blocks indicated by diagonal lines rising to the right represent search area set 92, blocks indicated by diagonal lines rising to the left represent search area set 93, and blocks indicated by horizontal lines represent search area set 94.

[0203] The monitoring interval of search area set 91 is set to 1 slot, the monitoring offset of search area set 91 is set to 0 slot, and the monitoring pattern of search area set 91 is set to [1,0,0,0,0,0,0,1,0,0,0,0,0,0]. That is, the monitoring opportunities for search area set 91 correspond to the first OFDM symbol (OFDM symbol #0) and the eighth OFDM symbol (OFDM symbol #7) in each slot.

[0204] The monitoring interval of search area set 92 is set to 2 slots, the monitoring offset of search area set 92 is set to 0 slots, and the monitoring pattern of search area set 92 is set to [1,0,0,0,0,0,0,0,0,0,0,0,0,0,0]. That is, the monitoring opportunity for search area set 92 corresponds to the first OFDM symbol (OFDM symbol #0) in each of the even slots.

[0205] The monitoring interval of search area set 93 is set to 2 slots, the monitoring offset of search area set 93 is set to 0 slots, and the monitoring pattern of search area set 93 is set to [0,0,0,0,0,0,0,1,0,0,0,0,0,0], i.e., the monitoring opportunity for search area set 93 corresponds to the 8th OFDM symbol (OFDM symbol #7) in each of the even slots.

[0206] The monitoring interval of search area set 94 is set to 2 slots, the monitoring offset of search area set 94 is set to 1 slot, and the monitoring pattern of search area set 94 is set to [1,0,0,0,0,0,0,0,0,0,0,0,0,0,0]. That is, the monitoring opportunity for search area set 94 corresponds to the first OFDM symbol (OFDM symbol #0) in each odd slot.

[0207] The Type 0 PDCCH common search space set may be used at least for DCI formats with a Cyclic Redundancy Check (CRC) sequence scrambled by a System Information-Radio Network Temporary Identifier (SI-RNTI).

[0208] The Type 0aPDCCH common search space set may be used at least for DCI formats with a CRC (Cyclic Redundancy Check) sequence scrambled by a System Information-Radio Network Temporary Identifier (SI-RNTI).

[0209] The Type 1 PDCCH common search space set may be used at least for DCI formats with a CRC sequence scrambled by a Random Access-Radio Network Temporary Identifier (RA-RNTI) and / or a CRC sequence scrambled by a Temporary Cell-Radio Network Temporary Identifier (TC-RNTI).

[0210] A Type 2 PDCCH common search space set may be used for a DCI format with a CRC sequence scrambled by a Paging-Radio Network Temporary Identifier (P-RNTI).

[0211] The Type 3 PDCCH common search space set may be used for a DCI format with a CRC sequence scrambled by a Cell-Radio Network Temporary Identifier (C-RNTI).

[0212] The UE dedicated PDCCH search space set may be used at least for DCI formats with CRC sequences scrambled by the C-RNTI.

[0213] In downlink communication, the terminal device 1 detects a downlink DCI format. The detected downlink DCI format is used at least for PDSCH resource allocation. The detected downlink DCI format is also referred to as a downlink assignment. The terminal device 1 attempts to receive the PDSCH. Based on the PUCCH resource indicated based on the detected downlink DCI format, the terminal device 1 reports a HARQ-ACK corresponding to the PDSCH (a HARQ-ACK corresponding to a transport block included in the PDSCH) to the base station device 3.

[0214] In uplink communication, the terminal device 1 detects an uplink DCI format. The detected DCI format is used at least for PUSCH resource allocation. The detected uplink DCI format is also called an uplink grant. The terminal device 1 transmits the PUSCH.

[0215] In configured scheduling (configured grant), an uplink grant for scheduling a PUSCH is configured for each transmission period of the PUSCH. When a PUSCH is scheduled by an uplink DCI format, some or all of the information indicated by the uplink DCI format may be indicated by the uplink grant configured in the case of configured scheduling.

[0216] A plurality of SS / PBCH block candidates may be arranged in a half radio frame. The arranged plurality of SS / PBCH block candidates may be assigned candidate indices in ascending order on the time axis. For example, N SSB When SS / PBCH block candidates are arranged, the value of the candidate index ranges from 0 to N SSB It can also be -1.

[0217] For example, N in a half radio frame SSB The frequency resources of the SS / PBCH block candidates may be the same.

[0218] N in half radio frame SSB Each of the SS / PBCH block candidates may be assigned an SS / PBCH block index. For example, the SS / PBCH block index may be equal to the candidate index. For example, the SS / PBCH block index may be determined by the remainder of dividing the candidate index by a value Q, where Q may be indicated by a higher layer parameter.

[0219] The base station device 3 may report bitmap information to the terminal device 1. The terminal device 1 may determine an association between SS / PBCH block index and PRACH occasions based on the bitmap information. The bitmap information may be included in higher layer parameters.

[0220] For example, the bitmap information may be used to indicate a set of SS / PBCH blocks transmitted by the base station device 3. Based on the bitmap information, the terminal device 1 may recognize a pool of SS / PBCH block indices. The pool of SS / PBCH block indices is also referred to as an index pool. For example, if the bitmap information is 8 bits, the first bit may correspond to SS / PBCH block index 0, the second bit may correspond to SS / PBCH block index 1, and the Xth bit may correspond to SS / PBCH block index X-1. Also, if the Xth bit is set to 1, the terminal device 1 may include the SS / PBCH block index X-1 in the index pool. Also, if the Xth bit is set to 0, the terminal device 1 may not include the SS / PBCH block index X-1 in the index pool.

[0221] Let N be the number of SS / PBCH block indices contained in the index pool. SSB TX It is also called.

[0222] The procedure for determining the relationship between SS / PBCH block indexes and PRACH opportunities may be a procedure for mapping SS / PBCH block indexes to each of a plurality of PRACH opportunities in an association period, for example, the association period may be any of 10 ms, 20 ms, 40 ms, 80 ms, or 160 ms.

[0223] 9 is a diagram showing an example of a procedure for determining the relationship between SS / PBCH block indexes and PRACH opportunities according to one aspect of this embodiment. In FIG. 9, 9000 indicates an association period. 9001 to 9004 each indicate one PRACH opportunity in association period 9000. 9005 indicates an index pool. In FIG. 9, SS / PBCH block indices #2, #5, and #6 are included in index pool 9005.

[0224] In the example shown in FIG. 9, SS / PBCH block index #2 is associated with PRACH opportunities 9001 and 9004, SS / PBCH block index #5 is associated with PRACH opportunity 9002, and SS / PBCH block index #6 is associated with PRACH opportunity 9003.

[0225] As shown in Figure 9, the SS / PBCH block indices included in the index pool may be cyclically associated with the PRACH opportunities, where the PRACH opportunities may be ordered in ascending order in the frequency domain, followed by ordering in the time domain (frequency-first time-second).

[0226] For the procedure of determining the relationship between SS / PBCH block index and PRACH opportunity, N, R, and N total may be notified to at least the terminal device 1. N is a parameter indicating the number of SS / PBCH blocks associated with one PRACH opportunity. R is a parameter indicating the number of preambles for CBRA (Contention-Based Random-Access) assigned to one SS / PBCH block index among the random access preambles of one PRACH opportunity. N total is a parameter indicating the sum of the number of preambles for CBRA and the number of preambles for CFRA (Contention-Free Random-Access) among the random access preambles of one PRACH opportunity.

[0227] FIG. 9 shows an example where N is 1.

[0228] 10 is a diagram illustrating an example of a procedure for determining the relationship between SS / PBCH block indexes and PRACH opportunities according to one aspect of this embodiment. Fig. 10 illustrates an example in which N is 2. In Fig. 10, SS / PBCH block indices #2 and #5 are associated with PRACH opportunity 9001, SS / PBCH block indices #6 and #2 are associated with PRACH opportunity 9002, SS / PBCH block indices #5 and #6 are associated with PRACH opportunity 9003, and SS / PBCH block indices #2 and #5 are associated with PRACH opportunity 9004.

[0229] 10, the terminal device 1 may cyclically associate the SS / PBCH block index with one or more PRACH opportunities during an association period. The cyclic association method may be based on some or all of the following steps 1 to 4.

[0230] Step 1 may include sorting the SS / PBCH block indices contained in the index pool 9005 in ascending order.

[0231] In step 1, the internal index I V may be added.

[0232] Step 2 may include an operation of selecting the first SS / PBCH block index from index pool 9005. Alternatively, if N is greater than 1, it may include an operation of selecting the first through Nth SS / PBCH block indexes. The SS / PBCH block indexes are selected cyclically. The first SS / PBCH block index is the SS / PBCH block index next to the SS / PBCH block index selected as the Nth block index in the previous operation of step 2. If this operation of step 2 is the first, the first SS / PBCH block index is the smallest SS / PBCH block index included in index pool 9005. In the operation of step 2, the SS / PBCH block index is selected cyclically. For example, if the SS / PBCH block index selected as the Nth block index in the previous operation of step 2 was SS / PBCH block index #6, the SS / PBCH block index next to the SS / PBCH block index selected as the Nth block index is SS / PBCH block index #2. Also, if the SS / PBCH block index selected as the Nth in the previous operation of step 2 was SS / PBCH block index #5, the SS / PBCH block index next to the SS / PBCH block index selected as the Nth is SS / PBCH block index #6. Furthermore, in the current selection of SS / PBCH block indices, N-1 SS / PBCH block indices are selected from SS / PBCH block index #6 and SS / PBCH block index #2.

[0233] Note that step 2 is the internal index I v =mod((i n -1)*N+1,N SSB TX ),...I v =mod((i n -1)*N+N,N SSB TX) where i n is an internal index that is incremented after the execution of the operations in step 2. Also, i n The initial value of is 0.

[0234] Step 3 includes assigning the N SS / PBCH block indices selected in step 2 to one PRACH opportunity, and then selecting a PRACH opportunity following the one PRACH opportunity, where the ordering of the PRACH opportunities is based on the frequency-first-time-second rule.

[0235] Step 4 includes determining the end of the procedure. If the PRACH opportunity in step 3 is the last PRACH opportunity in the association period, the procedure ends. If the PRACH opportunity next to the PRACH opportunity in step 3 is selected, the procedure returns to step 2.

[0236] For example, N in one PRACH opportunity total / N random access preambles may be assigned to one SS / PBCH block index.

[0237] In FIG. 10, of the 64 random access preambles included in the PRACH opportunity 9001, the preambles with index 0 to index N total / N up to N-1 total 64 random access preambles included in the PRACH opportunity 9001 may be allocated to SS / PBCH block #2. total / N to index 2*N total / N up to N-1 total / N random access preambles may be allocated to SS / PBCH block #5.

[0238] In FIG. 10, of the 64 random access preambles included in the PRACH opportunity 9002, the preambles with index 0 to index N total / N up to N-1 total 64 random access preambles included in the PRACH opportunity 9002 may be allocated to SS / PBCH block #6. total / N to index 2*N total / N up to N-1 total / N random access preambles may be allocated to SS / PBCH block #2.

[0239] In FIG. 10, of the 64 random access preambles included in the PRACH opportunity 9003, the preambles with index 0 to index N total / N up to N-1 total 64 random access preambles included in the PRACH opportunity 9003 may be allocated to SS / PBCH block #5. total / N to index 2*N total / N up to N-1 total / N random access preambles may be allocated to SS / PBCH block #6.

[0240] In FIG. 10, of the 64 random access preambles included in the PRACH opportunity 9004, the preambles with index 0 to index N total / N up to N-1 total 64 random access preambles included in the PRACH opportunity 9004 may be allocated to SS / PBCH block #2. total / N to index 2*N total / N up to N-1 total / N random access preambles may be allocated to SS / PBCH block #5.

[0241] Thus, the allocation of random access preambles to SS / PBCH block indices is N and N total The determination may be based on at least one or both of the following:

[0242] In one PRACH opportunity, N assigned to a certain SS / PBCH block index total Among the / N random access preambles, R random access preambles may be random access preambles for CBRA. The terminal device 1 may determine the random access preambles for CBRA based at least on R.

[0243] For example, the terminal device 1 may select N SS / PBCH block indexes assigned to a certain SS / PBCH block index in one PRACH opportunity. total / N random access preambles, index (n-1)*N total / N to index (n-1)*N total / N+R−1 random access preambles may be determined as random access preambles for CBRA, where n corresponds to the nth selected SS / PBCH block index among the N SS / PBCH block indices selected for one PRACH opportunity, and the value of n ranges from 1 to N.

[0244] In CBRA, the terminal device 1 may select one random access preamble for CBRA from among random access preambles associated with a certain SS / PBCH block index. For example, the certain SS / PBCH block index may be indicated by a parameter of a higher layer. Also, the certain SS / PBCH block index may be indicated by a DCI format. Also, if the certain SS / PBCH block index is not notified by a radio signal transmitted from the base station device 3, the terminal device 1 may select one from one or more SS / PBCH blocks detected by the terminal device 1 based at least on the reception strength.

[0245] In a wireless communication system according to one aspect of the present embodiment, an extension function of the PUSCH may be added when the PUSCH transmitted by the terminal device 1 located at a cell edge cannot be properly received by the base station device 3. For example, by repeating the transmission of the PUSCH by the terminal device 1, it is possible to increase the transmission power per modulation symbol transmitted in the PUSCH, and performance improvement is expected.

[0246] When a PUSCH is scheduled for an RRC-connected terminal device 1 in a DCI format with a CRC sequence scrambled by C-RNTI, the base station device 3 may notify the terminal device 1 of whether or not to add an extended function to the PUSCH. The base station device 3 may decide whether or not to add an extended function to the PUSCH based on CSI reported by the terminal device 1 or reception quality information based on wireless section measurements, etc. For example, the reception quality information may be RSRP (Reference Signal Received Power).

[0247] On the other hand, for a terminal device 1 that is not RRC connected, the report is not sent from the terminal device 1, or the base station device 3 cannot identify the terminal device 1, so it may be difficult for the base station device 3 to decide whether to add an extension function to the PUSCH scheduled based on the random access response grant.

[0248] In CBRA, the terminal device 1 may determine the SS / PBCH block index of the SS / PBCH block with the highest RSRP among one or more received SS / PBCH blocks. The terminal device 1 may also determine whether the highest RSRP satisfies a predetermined condition. For example, the predetermined condition may be a condition based on a comparison between the highest RSRP and a predetermined threshold. The predetermined condition may also be a condition based on whether the highest RSRP is greater than a predetermined threshold. The predetermined condition may also be a condition based on whether the highest RSRP is smaller than a predetermined threshold.

[0249] The terminal device 1 may select either the first set of random access preambles for CBRA or the second set of random access preambles for CBRA based on whether the predetermined condition is satisfied. The first set of random access preambles for CBRA may be a set selected when the predetermined condition is not satisfied. Also, the second set of random access preambles for CBRA may be a set selected when the predetermined condition is satisfied. If a determination based on the predetermined condition is not made, the first set of random access preambles for CBRA may be selected.

[0250] The set of first random access preambles corresponds to the first random access procedure. That is, when the implementation of the first random access procedure is notified by an upper layer of the terminal device 1, one random access preamble may be selected from the set of first random access preambles. The selected random access preamble may be transmitted in the selected PRACH opportunity.

[0251] The first random access procedure may be a four-step random access.

[0252] The set of second random access preambles corresponds to the second random access procedure. That is, when the implementation of the second random access procedure is notified by an upper layer of the terminal device 1, one random access preamble may be selected from the set of second random access preambles. The selected random access preamble may be transmitted in the selected PRACH opportunity.

[0253] The second random access procedure may be a four-step random access procedure that is different from the first random access procedure, for example, the second random access procedure may be a method in which an extended function is added to the first random access procedure.

[0254] The set of first random access preambles for CBRA may be determined based on first RACH configuration information included in the RRC message, which includes at least some or all of R1 to R7 below. R1) PRACH configuration index R2) Number of frequency-multiplexed PRACH opportunities R3) Random Access Response Window R4) Sum of random access preambles R5) Number of SS / PBCH blocks associated with one PRACH opportunity R6) Number of preambles for CBRA R7) Message 3 transmission method

[0255] The PRACH configuration index is an index used at least to determine the index of the subframe in which the PRACH opportunity is located, and part or all of the time location of the PRACH within the slot (such as the index of the first OFDM symbol).

[0256] The same number of PRACH opportunities as the number of frequency-multiplexed PRACH opportunities can be set in the frequency domain.

[0257] The random access response window indicates a period (window) during which the terminal device 1 monitors a random access response corresponding to the random access preamble after transmitting the random access preamble.

[0258] The sum of the random access preambles is N total Shows.

[0259] The number of SS / PBCH blocks associated with one PRACH opportunity is denoted as N.

[0260] The number of preambles for CBRA is denoted by R.

[0261] The message 3 transmission scheme indicates whether modified precoding is used in the transmission scheme used for the PUSCH of message 3.

[0262] The set of second random access preambles for CBRA may be determined based on second RACH configuration information included in the RRC message, which includes at least some or all of R1 to R7 below.

[0263] For example, a PRACH opportunity configured for a first random access procedure and a PRACH opportunity configured for a second random access procedure may share the same resources, which is also referred to as a first-second shared configuration.

[0264] For example, the PRACH opportunities configured for the first random access procedure and at least some of the PRACH opportunities configured for the second random access procedure may use different resources, which are also referred to as first and second dedicated configurations.

[0265] For example, in the first and second shared configuration, the second RACH configuration information is the number R of preambles for CBRA. xThe terminal device 1 may include at least N assigned to a certain SS / PBCH block index in one PRACH opportunity. total / N random access preambles, index (n-1)*N total / N+R to index (n-1)*N total / N+R+R x The random access preambles up to -1 may be determined to be the second set of random access preambles for CBRA.

[0266] For example, in the first and second individual settings, the terminal device 1 selects N SS / PBCH block indexes assigned to a certain SS / PBCH block index in one PRACH opportunity. total / N random access preambles, index (n-1)*N total / N to index (n-1)*N total The random access preambles up to / N+R-1 may be determined to be a second set of random access preambles for CBRA.

[0267] Based on condition 1, the terminal device 1 may select either a first set of random access preambles for CBRA, a second set of random access preambles for CBRA, or a third set of random access preambles for CBRA.

[0268] The condition 1 may be based on at least two thresholds related to RSRP. For example, if the largest RSRP is between threshold A and threshold B, the terminal device 1 may select a first set of random access preambles for the CBRA. If the largest RSRP is smaller than threshold B, the terminal device 1 may select a second set of random access preambles for the CBRA. If the largest RSRP is larger than threshold A, the terminal device 1 may select a third set of random access preambles for the CBRA.

[0269] The set of third random access preambles corresponds to the third random access procedure. That is, when the implementation of the third random access procedure is notified by an upper layer of the terminal device 1, one random access preamble may be selected from the set of third random access preambles. The selected random access preamble may be transmitted in the selected PRACH opportunity.

[0270] The third random access procedure may be a two-step random access. In the two-step random access, the terminal device 1 transmits a message A to the base station device 3. The message A includes a PRACH and a PUSCH. Furthermore, the base station device 3 that receives the message A transmits a message B to the terminal device 1. The message B includes a PDSCH.

[0271] The set of third random access preambles for CBRA may be determined based on third RACH configuration information included in the RRC message, which includes at least some or all of the following R1 to R7.

[0272] For example, the PRACH opportunity configured for the first random access procedure and the PRACH opportunity configured for the third random access procedure may share the same resources, which is also referred to as a first-third shared configuration.

[0273] For example, the PRACH opportunities configured for the first random access procedure and at least some of the PRACH opportunities configured for the third random access procedure may use different resources, which are also referred to as first and third dedicated configurations.

[0274] For example, in the first and third shared configuration, the third RACH configuration information is the number R of preambles for CBRA. zThe terminal device 1 may include at least N assigned to a certain SS / PBCH block index in one PRACH opportunity. total / N random access preambles, index (n-1)*N total / N+R to index (n-1)*N total / N+R+R z The random access preambles up to -1 may be determined to be the third set of random access preambles for CBRA.

[0275] For example, the PRACH opportunity set for the first random access procedure, the PRACH opportunity set for the second random access procedure, and the PRACH opportunity set for the third random access procedure may share the same resources. Since the terminal device 1 may not necessarily be able to recognize the third random access procedure, the method for determining the set of the second random access preamble may be changed.

[0276] For example, in the first and second shared configuration, the second RACH configuration information is the number R of preambles for CBRA. x The terminal device 1 may include at least N assigned to a certain SS / PBCH block index in one PRACH opportunity. total / N random access preambles, index (n-1)*N total / N+S x From index (n-1)*N total / N+S x +R x The random access preambles S up to S -1 may be determined to be the second set of random access preambles for CBRA, where S x may be indicated by a parameter included in the second RACH configuration information.

[0277] For example, in the first and second shared configuration, the second RACH configuration information is the number R of preambles for CBRA. xThe terminal device 1 may include at least N assigned to a certain SS / PBCH block index in one PRACH opportunity. total / N random access preambles with index n*S y from index n*S y +R x The random access preambles S up to S -1 may be determined to be the second set of random access preambles for CBRA, where S y may be indicated by a parameter included in the second RACH configuration information.

[0278] For example, in the first and second shared configuration, the second RACH configuration information is the number R of preambles for CBRA. Y The terminal device 1 may include at least N assigned to a certain SS / PBCH block index in one PRACH opportunity. total / N random access preambles, index (n-1)*R Y +N total to index n*R Y +N total The random access preambles up to -1 may be determined to be the second set of random access preambles for CBRA.

[0279] For example, in the first and third individual settings, the terminal device 1 selects N SS / PBCH block indexes assigned to a certain SS / PBCH block index in one PRACH opportunity. total / N random access preambles, index (n-1)*N total / N to index (n-1)*N total The random access preambles up to / N+R-1 may be determined to be the third set of random access preambles for CBRA.

[0280] Based on condition 2, the terminal device 1 may select any one of a first set of random access preambles for CBRA, a second set of random access preambles for CBRA, a third set of random access preambles for CBRA, or a fourth set of random access preambles for CBRA.

[0281] The fourth set of random access preambles corresponds to the fourth random access procedure. That is, when the implementation of the fourth random access procedure is notified by an upper layer of the terminal device 1, one random access preamble may be selected from the fourth set of random access preambles. The selected random access preamble may be transmitted in the selected PRACH opportunity.

[0282] The fourth random access procedure may be a method in which an extended function is added to the third random access procedure.

[0283] Condition 2 may be based on at least two thresholds related to RSRP. For example, threshold C may be used to switch between four-step random access and two-step random access. Threshold D may be used to switch whether an extended function is used in the random access procedure. For example, if the largest RSRP is greater than threshold C, two-step random access may be selected. If the largest RSRP is equal to threshold C, two-step random access may be selected, or four-step random access may be selected. If the largest RSRP is smaller than threshold C, four-step random access may be selected.

[0284] For example, if a two-step random access is selected based on threshold C, the third random access procedure may be selected if the largest RSRP is greater than threshold D. Alternatively, if the largest RSRP is equal to threshold D, the third random access procedure or the fourth random access procedure may be selected. Alternatively, if the largest RSRP is smaller than threshold D, the fourth random access procedure may be selected.

[0285] For example, when a four-step random access is selected based on threshold C, if the largest RSRP is greater than threshold D, the first random access procedure may be selected. Alternatively, if the largest RSRP is equal to threshold D, the first random access procedure or the second random access procedure may be selected. Alternatively, if the largest RSRP is less than threshold D, the second random access procedure may be selected.

[0286] Condition 2 may be based on at least three thresholds related to RSRP. For example, threshold C may be used to switch between four-step random access and two-step random access. Threshold D1 may be used to switch whether an extended function is used in the four-step random access procedure. Threshold D2 may be used to switch whether an extended function is used in the two-step random access procedure. For example, if the largest RSRP is greater than threshold C, two-step random access may be selected. If the largest RSRP is equal to threshold C, two-step random access may be selected, or four-step random access may be selected. If the largest RSRP is smaller than threshold C, four-step random access may be selected.

[0287] For example, if two-step random access is selected based on threshold C, the third random access procedure may be selected if the largest RSRP is greater than threshold D2. Alternatively, if the largest RSRP is equal to threshold D2, the third random access procedure or the fourth random access procedure may be selected. Alternatively, if the largest RSRP is less than threshold D2, the fourth random access procedure may be selected.

[0288] For example, when a four-step random access is selected based on threshold C, if the largest RSRP is greater than threshold D1, the first random access procedure may be selected. Alternatively, if the largest RSRP is equal to threshold D1, either the first random access procedure or the second random access procedure may be selected. Alternatively, if the largest RSRP is less than threshold D1, the second random access procedure may be selected.

[0289] For example, in the first random access procedure, after transmitting a random access preamble, a DCI format used for scheduling a PDSCH including a random access response may be monitored for a predetermined period. The predetermined period may be determined by a value indicated by a random access response window included in the first RACH configuration information. The CRC sequence added to the DCI format is scrambled with the RA-RNTI.

[0290] For example, if the terminal device 1 detects the DCI format within the predetermined period, it may attempt to decode a PDSCH scheduled by the DCI format. The PDSCH may include one or more random access responses. If the terminal device 1 finds a random access response including information matching the index of the random access preamble transmitted in the first random access procedure, the terminal device 1 may transmit a PUSCH scheduled by a first random access response grant included in the found random access response.

[0291] Here, the first random access response grant may include at least a time domain resource allocation field. Here, the time domain resource allocation field indicates one of the columns included in a first Time Domain Resource Assignment (TDRA) table. The first TDRA table may include one or more columns. Information corresponding to one column may include at least some or all of K2, a Start and Length Indicator Value (SLIV), and a DMRS mapping type. Here, K2 may be used to indicate a slot in which the PUSCH is transmitted. If the slot in which the PUSCH is transmitted is n, the random access response is transmitted at n-K2. The SLIV may be used to indicate the first OFDM symbol of the PUSCH within the slot and the length of the PUSCH. The DMRS mapping type may be used to indicate the type of DMRS allocation for the PUSCH.

[0292] The first TDRA table may not use PUSCH repetition.

[0293] For example, in the second random access procedure, after transmitting a random access preamble, a DCI format used for scheduling a PDSCH including a random access response may be monitored for a predetermined period. The predetermined period may be determined by a value indicated by a random access response window included in the second RACH configuration information. If the second RACH configuration information does not include information indicating a random access response window, the predetermined period may be determined by a value indicated by a random access response window included in the first RACH configuration information. The CRC sequence added to the DCI format is scrambled with the RA-RNTI.

[0294] For example, if the terminal device 1 detects the DCI format within the predetermined period, it may attempt to decode a PDSCH scheduled by the DCI format. The PDSCH may include one or more random access responses. If the terminal device 1 finds a random access response including information matching the index of the random access preamble transmitted in the first random access procedure, the terminal device 1 may transmit a PUSCH scheduled by a second random access response grant included in the found random access response.

[0295] Here, the second random access response grant may include at least a time-domain resource allocation field. Here, the time-domain resource allocation field indicates one of the columns included in the second TDRA table. The second TDRA table may include one or more columns. Information corresponding to one column may include at least some or all of K2, a Start and Length Indicator Value (SLIV), and a DMRS mapping type. Here, K2 may be used to indicate a slot in which the PUSCH is transmitted. If the slot in which the PUSCH is transmitted is n, the random access response is transmitted at n-K2. The SLIV may be used to indicate the first OFDM symbol of the PUSCH within the slot and the length of the PUSCH. The DMRS mapping type may be used to indicate the type of DMRS allocation for the PUSCH.

[0296] The second TDRA table may be different from the first TDRA table.

[0297] For example, the second TDRA table may include information used to determine the number of times a PUSCH is repeated, For example, the second TDRA table may include information indicating the number of times a PUSCH is repeated.

[0298] If the information corresponding to one column indicated by the time domain resource allocation field includes information indicating the number of times the PUSCH is repeated, K2 may be used to indicate the first slot of multiple slots in which the PUSCH is transmitted.

[0299] Fig. 11 is a diagram showing an example of a first PUSCH repetition type according to one aspect of this embodiment. In Fig. 11, the horizontal axis represents the time domain. Grid lines on the time domain represent slot boundaries. The time domains corresponding to the hatched blocks indicate that the time domains are downlink. The fact that the time domains are downlink indicates that the OFDM symbols included in the time domains are downlink symbols. The time domains corresponding to the white blocks indicate that the time domains are flexible regions. The fact that the time domains are flexible regions indicates that the OFDM symbols included in the time domains are flexible symbols. The time domains corresponding to the grid line blocks indicate that the time domains are uplink. The fact that the time domains are uplink indicates that the OFDM symbols included in the time domains are uplink symbols.

[0300] In Fig. 11, a PDSCH 11000 including a random access response is transmitted in the downlink domain. Furthermore, PUSCHs scheduled by a random access response grant included in the random access response are assigned to PUSCHs 11001 to 11004. Here, the random access response grant indicates that K2 is 2 and the number of PUSCH repetitions is 4. As shown in Fig. 11, in the first PUSCH repetition type, the PUSCH may be repeatedly transmitted in multiple slots. Furthermore, each of the repeatedly transmitted PUSCH resources may start from the same OFDM symbol within the slot. Furthermore, each of the repeated PUSCH resources may be configured with the same number of OFDM symbols.

[0301] In the first PUSCH repetition type, whether or not PUSCH transmission is performed may be determined based on a TDD (Time Division Duplex) pattern. For example, in a certain slot, based on the fact that some or all of a set of OFDM symbols constituting PUSCH resources according to the TDD pattern are set as downlink symbols, transmission may not be performed in the PUSCH resources. Also, in a certain slot, based on the fact that none of the OFDM symbols in a set of OFDM symbols constituting PUSCH resources according to the TDD pattern are set as downlink symbols, transmission may be performed in the PUSCH resources.

[0302] The TDD pattern is a collective term for the first TDD pattern setting, the second TDD pattern setting, and the third TDD pattern setting.

[0303] The first TDD pattern configuration may be provided by first TDD pattern configuration information included in an RRC message, and may include some or all of T1 to T6. T1) Reference subcarrier spacing u ref T2) Slot setting period P T3) Number of downlink slots d slots T4) Number of uplink slots u sym T5) Number of downlink symbols d sym T6) Number of uplink symbols u sym

[0304] Reference subcarrier spacing u ref indicates the subcarrier spacing used to determine the configuration of slots T2 to T6.

[0305] The period of the pattern determined by part or all of T3 to T6 is determined based on the slot setting period P. The number of slots S included in one period of the pattern is S=P*2^uref In the first TDD pattern configuration, the pattern may be repeated based on the period of the pattern.

[0306] Number of downlink slots d slot is the first d of the S slots slot indicates that the OFDM symbols included in are downlink symbols.

[0307] Number of uplink slots u slot is the rear u of the S slot slot indicates that the OFDM symbols included in are uplink symbols.

[0308] Number of downlink symbols d sym is the number of S slots from the beginning to the end of d slot Later d sym Indicates that this OFDM symbol is a downlink symbol.

[0309] Number of uplink symbols u sym is the S slot from the rear d slot u before sym Indicates that this OFDM symbol is an uplink symbol.

[0310] That is, among the S slots, d from the beginning slot *N slot symb +d sym The OFDM symbols may be downlink symbols. slot *N slot symb +u sym OFDM symbols may be uplink symbols. Also, S*N slot symb -(d slot *N slot symb +d sym +u slot *N slot symb+u sym ) OFDM symbols may be flexible symbols.

[0311] If no first TDD pattern configuration information is provided, the first TDD pattern configuration may include only the flexible region.

[0312] The first TDD pattern setting information may include information for setting Pattern 2. The information for setting Pattern 2 includes at least some or all of T3 to T6. When Pattern 2 is set, a pattern combining Pattern 2 with Pattern 2 may be configured to be periodically repeated.

[0313] The second pattern configuration may be provided by second pattern configuration information included in the RRC message. The second pattern configuration information includes one or more pieces of slot-specific configuration information. Each piece of slot-specific configuration information may include information indicating a slot index and the slot configuration information.

[0314] The information indicating the slot index included in the individual slot setting information may specify a slot to which the setting based on the slot setting information included in the individual slot setting information is applied. The information indicating the slot index may indicate a slot index within the S slot.

[0315] The slot setting information may indicate one of a first setting, a second setting, and a third setting. The first setting may be a setting indicating that the OFDM symbols included in the slot specified by the information indicating the slot index are downlink symbols. The second setting may be a setting indicating that the OFDM symbols included in the slot specified by the information indicating the slot index are uplink symbols. The third setting may be a setting indicating that the number d of downlink symbols in a slot is sym2 and the number of uplink symbols in the slot, u sym2In the third setting, the first d of the slot specified by the information indicating the slot index may be sym2 In the third configuration, the OFDM symbols may be downlink symbols. sym2 In the third configuration, among the slots identified by the information indicating the slot index, an OFDM symbol that is neither a downlink symbol nor an uplink symbol may be a flexible symbol.

[0316] An OFDM symbol set as a downlink symbol in the first TDD pattern configuration may not be set as an uplink symbol in the second TDD pattern configuration, and an OFDM symbol set as an uplink symbol in the first TDD pattern configuration may not be set as a downlink symbol in the second TDD pattern configuration.

[0317] For example, when a first TDD pattern configuration and a second TDD pattern configuration are provided to the terminal device 1, for a PUSCH scheduled by a first random access response grant, the second TDD pattern configuration may be referenced to determine whether transmission is to be performed in the PUSCH resource in each slot. Here, for example, when at least a part or all of a set of OFDM symbols constituting the PUSCH resource in a certain slot are configured for downlink by the second TDD pattern configuration, transmission may not be performed in the resource. Also, when none of the sets of OFDM symbols constituting the PUSCH resource in a certain slot are configured for downlink by the second TDD pattern configuration, transmission may be performed in the resource.

[0318] For example, when a first TDD pattern configuration and a second TDD pattern configuration are provided to the terminal device 1, for a PUSCH scheduled by a second random access response grant, the first TDD pattern configuration may be referenced to determine whether transmission is to be performed in the PUSCH resource in each slot. Here, for example, when at least a part or all of a set of OFDM symbols constituting the PUSCH resource in a certain slot are configured for downlink by the first TDD pattern configuration, transmission may not be performed in the resource. Also, when none of the sets of OFDM symbols constituting the PUSCH resource in a certain slot are configured for downlink by the first TDD pattern configuration, transmission may be performed in the resource.

[0319] For example, when a first TDD pattern configuration and a second TDD pattern configuration are provided to the terminal device 1 and a first PUSCH repetition type is applied to a PUSCH scheduled by a second random access response grant, the first TDD pattern configuration may be referenced to determine whether transmission is performed in a PUSCH resource in each slot. For example, when at least a part or all of a set of OFDM symbols constituting the PUSCH resource in a certain slot are configured for downlink by the first TDD pattern configuration, transmission may not be performed in the resource. Also, when none of the sets of OFDM symbols constituting the PUSCH resource in a certain slot are configured for downlink by the first TDD pattern configuration, transmission may be performed in the resource.

[0320] For example, when a first TDD pattern configuration and a second TDD pattern configuration are provided to the terminal device 1 and the first PUSCH repetition type is not applied to the PUSCH scheduled by the second random access response grant, the second TDD pattern configuration may be referenced to determine whether or not transmission is to be performed in the PUSCH resource in each slot. For example, when at least a part or all of a set of OFDM symbols constituting the PUSCH resource in a certain slot are configured for downlink by the second TDD pattern configuration, transmission may not be performed in the resource. Also, when none of the sets of OFDM symbols constituting the PUSCH resource in a certain slot are configured for downlink by the second TDD pattern configuration, transmission may be performed in the resource.

[0321] For example, when a first TDD pattern configuration and a second TDD pattern configuration are provided to the terminal device 1, a first PUSCH repetition type is applied to a PUSCH scheduled by a second random access response grant, and a C-RNTI is reported to the base station device 3 by the PUSCH, the first TDD pattern configuration may be referenced to determine whether or not transmission is to be performed in a PUSCH resource in each slot. For example, when at least a part or all of a set of OFDM symbols constituting the PUSCH resource in a certain slot are configured for downlink by the first TDD pattern configuration, transmission may not be performed in the resource. Also, when none of the sets of OFDM symbols constituting the PUSCH resource in a certain slot are configured for downlink by the first TDD pattern configuration, transmission may be performed in the resource.

[0322] For example, when a first TDD pattern configuration and a second TDD pattern configuration are provided to the terminal device 1, a first PUSCH repetition type is applied to a PUSCH scheduled by a second random access response grant, and a C-RNTI is not reported to the base station device 3 by the PUSCH, the second TDD pattern configuration may be referenced to determine whether or not transmission is to be performed in the PUSCH resource in each slot. For example, when at least a part or all of a set of OFDM symbols constituting the PUSCH resource in a certain slot are configured for downlink by the second TDD pattern configuration, transmission may not be performed in the resource. Also, when none of the sets of OFDM symbols constituting the PUSCH resource in a certain slot are configured for downlink by the second TDD pattern configuration, transmission may be performed in the resource.

[0323] Fig. 12 is a diagram showing an example of a second PUSCH repetition type according to one aspect of this embodiment. In Fig. 12, the horizontal axis represents the time domain. Grid lines on the time domain indicate slot boundaries. The time domain corresponding to the hatched blocks indicates that the time domain is a downlink. The time domain corresponding to the white blocks indicates that the time domain is a flexible region. The time domain corresponding to the grid line blocks indicates that the time domain is an uplink.

[0324] In Fig. 12, a PDSCH 12000 including a random access response is transmitted in the downlink domain. Furthermore, PUSCHs scheduled by a random access response grant included in the random access response are allocated to PUSCHs 12001 to 12008. Here, the random access response grant indicates that K2 is 2 and the number of PUSCH repetitions is 8. As shown in Fig. 12, in the second PUSCH repetition type, PUSCH resources may be arranged contiguously. Each of the PUSCH resources shown in Fig. 12 is also referred to as a nominal repetition.

[0325] 12, actual repetition resources may be set based on the TDD pattern configuration. The terminal device 1 may transmit the PUSCH using the actual repetition resources set based on the TDD pattern configuration.

[0326] 13 is a diagram showing an example of configuring actual repetition resources according to one aspect of the present embodiment. Since the set of OFDM symbols constituting PUSCH 12001 in FIG. 12 does not include a downlink symbol, the nominal repetition resources of PUSCH 12001 are configured as actual repetition resources. PUSCH 12002, PUSCH 12006, PUSCH 12007, and PUSCH 12008 are the same as PUSCH 12001. In other words, based on the fact that the set of OFDM symbols constituting the nominal repetition resources does not include a downlink symbol, the resources may be configured as actual repetition resources.

[0327] 13, since the set of OFDM symbols constituting PUSCH 12003 includes only downlink symbols, the nominal repetition resource of PUSCH 12003 does not have to be configured as an actual repetition resource. PUSCH 12004 is the same as PUSCH 12003. In other words, since the set of OFDM symbols constituting the nominal repetition resource includes only downlink symbols, the resource does not have to be set as an actual repetition resource.

[0328] 13, since the set of OFDM symbols constituting PUSCH 12005 includes downlink symbols and flexible symbols, resources in the flexible region are set as actual repetition resources among the resources of PUSCH 12005. In other words, based on the fact that the set of OFDM symbols constituting nominal repetition resources includes downlink symbols and symbols other than downlink symbols, resources excluding the OFDM symbols of downlink symbols may be set as actual repetition resources.

[0329] Symbols other than downlink symbols are a collective term for flexible symbols and uplink symbols.

[0330] For example, when a first TDD pattern configuration and a second TDD pattern configuration are provided to the terminal device 1, the actual repetition resource may be determined for the PUSCH scheduled by the first random access response grant by referring to the second TDD pattern configuration. Here, for example, when all of a set of OFDM symbols constituting a certain nominal repetition are configured for at least the downlink by the second TDD pattern configuration, the resource may not be configured as the actual repetition resource. Also, when the set of OFDM symbols constituting the certain nominal repetition includes downlink symbols and symbols other than the downlink symbols by the second TDD pattern configuration, the resource constituted by the symbols other than the downlink symbols may be configured as the actual repetition resource.

[0331] For example, when a first TDD pattern configuration and a second TDD pattern configuration are provided to the terminal device 1, the actual repetition resource may be determined for a PUSCH scheduled by a second random access response grant by referring to the first TDD pattern configuration. Here, for example, when all of a set of OFDM symbols constituting a certain nominal repetition are configured for at least the downlink by the first TDD pattern configuration, the resource may not be configured as the actual repetition resource. Also, when the set of OFDM symbols constituting the certain nominal repetition by the first TDD pattern configuration includes downlink symbols and symbols other than the downlink symbols, the resource constituted by the symbols other than the downlink symbols may be configured as the actual repetition resource.

[0332] For example, when a first TDD pattern configuration and a second TDD pattern configuration are provided to the terminal device 1 and a second PUSCH repetition type is applied to a PUSCH scheduled by a second random access response grant, the actual repetition resource for the PUSCH scheduled by the second random access response grant may be determined by referring to the first TDD pattern configuration. Here, for example, when all of a set of OFDM symbols constituting a certain nominal repetition are configured for at least the downlink by the first TDD pattern configuration, the resource does not need to be configured as the actual repetition resource. Also, when the set of OFDM symbols constituting the certain nominal repetition includes downlink symbols and symbols other than the downlink symbols by the first TDD pattern configuration, the resource constituted by the symbols other than the downlink symbols may be configured as the actual repetition resource.

[0333] For example, when a first TDD pattern configuration and a second TDD pattern configuration are provided to the terminal device 1 and a second PUSCH repetition type is not applied to a PUSCH scheduled by a second random access response grant, the terminal device 1 may determine an actual repetition resource for the PUSCH scheduled by the second random access response grant by referring to the second TDD pattern configuration. Here, for example, when all of a set of OFDM symbols constituting a certain nominal repetition are configured for at least the downlink by the second TDD pattern configuration, the resource does not need to be configured as an actual repetition resource. Furthermore, when the set of OFDM symbols constituting the certain nominal repetition includes a downlink symbol and a symbol other than the downlink symbol by the second TDD pattern configuration, the resource constituted by the symbols other than the downlink symbol may be configured as an actual repetition resource.

[0334] For example, when a first TDD pattern configuration and a second TDD pattern configuration are provided to the terminal device 1, a second PUSCH repetition type is applied to a PUSCH scheduled by a second random access response grant, and a C-RNTI is reported to the base station device 3 by the PUSCH, the actual repetition resource for the PUSCH scheduled by the second random access response grant may be determined by referring to the first TDD pattern configuration. Here, for example, when all of a set of OFDM symbols constituting a certain nominal repetition are configured for at least the downlink by the first TDD pattern configuration, the resource does not need to be configured as the actual repetition resource. Furthermore, when the set of OFDM symbols constituting the certain nominal repetition includes downlink symbols and symbols other than the downlink symbols by the first TDD pattern configuration, the resource constituted by the symbols other than the downlink symbols may be configured as the actual repetition resource.

[0335] For example, when a first TDD pattern configuration and a second TDD pattern configuration are provided to the terminal device 1, a second PUSCH repetition type is applied to a PUSCH scheduled by a second random access response grant, and a C-RNTI is not reported to the base station device 3 by the PUSCH, the actual repetition resource for the PUSCH scheduled by the second random access response grant may be determined by referring to the second TDD pattern configuration. Here, for example, when all of a set of OFDM symbols constituting a certain nominal repetition are configured for at least the downlink by the second TDD pattern configuration, the resource does not need to be configured as the actual repetition resource. Furthermore, when the set of OFDM symbols constituting the certain nominal repetition includes downlink symbols and symbols other than the downlink symbols by the second TDD pattern configuration, the resource constituted by the symbols other than the downlink symbols may be configured as the actual repetition resource.

[0336] For example, when a first TDD pattern configuration and a second TDD pattern configuration are provided to the terminal device 1, for the PUSCH transmitted together with the PRACH in message A of the third random access procedure, the second TDD pattern configuration may be referenced to determine whether transmission is to be performed in the PUSCH resource in each slot. Here, for example, when at least a part or all of a set of OFDM symbols constituting the PUSCH resource in a certain slot are configured for downlink by the second TDD pattern configuration, transmission may not be performed in the resource. Also, when none of the sets of OFDM symbols constituting the PUSCH resource in a certain slot are configured for downlink by the second TDD pattern configuration, transmission may be performed in the resource.

[0337] For example, when a first TDD pattern configuration and a second TDD pattern configuration are provided to the terminal device 1, for the PUSCH transmitted together with the PRACH in message A of the fourth random access procedure, the first TDD pattern configuration may be referenced to determine whether or not transmission is to be performed in the PUSCH resource in each slot. Here, for example, when at least a part or all of a set of OFDM symbols constituting the PUSCH resource in a certain slot are configured for downlink by the first TDD pattern configuration, transmission may not be performed in the resource. Also, when none of the sets of OFDM symbols constituting the PUSCH resource in a certain slot are configured for downlink by the first TDD pattern configuration, transmission may be performed in the resource.

[0338] For example, when a first TDD pattern configuration and a second TDD pattern configuration are provided to the terminal device 1 and a first PUSCH repetition type is applied to the PUSCH transmitted together with the PRACH in message A of the fourth random access procedure, it may be determined whether or not transmission is performed in the PUSCH resource in each slot by referring to the first TDD pattern configuration. For example, when at least a part or all of a set of OFDM symbols constituting the PUSCH resource in a certain slot are configured for downlink by the first TDD pattern configuration, transmission may not be performed in the resource. Also, when none of the sets of OFDM symbols constituting the PUSCH resource in a certain slot are configured for downlink by the first TDD pattern configuration, transmission may be performed in the resource.

[0339] For example, when a first TDD pattern configuration and a second TDD pattern configuration are provided to the terminal device 1 and the first PUSCH repetition type is not applied to the PUSCH transmitted together with the PRACH in message A of the fourth random access procedure, the second TDD pattern configuration may be referenced to determine whether or not transmission is to be performed in the PUSCH resource in each slot. For example, when at least a part or all of a set of OFDM symbols constituting the PUSCH resource in a certain slot are configured for downlink by the second TDD pattern configuration, transmission may not be performed in the resource. Also, when none of the sets of OFDM symbols constituting the PUSCH resource in a certain slot are configured for downlink by the second TDD pattern configuration, transmission may be performed in the resource.

[0340] For example, when a first TDD pattern configuration and a second TDD pattern configuration are provided to the terminal device 1, a first PUSCH repetition type is applied to the PUSCH transmitted together with the PRACH in message A of the fourth random access procedure, and a C-RNTI is reported to the base station device 3 via the PUSCH, the first TDD pattern configuration may be referenced to determine whether transmission is to be performed in the PUSCH resource in each slot. For example, when at least some or all of a set of OFDM symbols constituting the PUSCH resource in a certain slot are configured for downlink by the first TDD pattern configuration, transmission may not be performed in the resource. Also, when none of the sets of OFDM symbols constituting the PUSCH resource in a certain slot are configured for downlink by the first TDD pattern configuration, transmission may be performed in the resource.

[0341] For example, when a first TDD pattern configuration and a second TDD pattern configuration are provided to the terminal device 1, a first PUSCH repetition type is applied to the PUSCH transmitted together with the PRACH in message A of the fourth random access procedure, and a C-RNTI is not reported to the base station device 3 by the PUSCH, the second TDD pattern configuration may be referenced to determine whether or not transmission is to be performed in the PUSCH resource in each slot.

Also, when none of the sets of OFDM symbols constituting the PUSCH resource in a certain slot are configured for downlink by the second TDD pattern configuration, transmission may be performed in the resource.

[0342] For example, when a first TDD pattern configuration and a second TDD pattern configuration are provided to the terminal device 1, the actual repetition resource may be determined for the PUSCH transmitted together with the PRACH in message A of the third random access procedure by referring to the second TDD pattern configuration. Here, for example, when all of a set of OFDM symbols constituting a certain nominal repetition are configured for at least the downlink by the second TDD pattern configuration, the resource may not be configured as the actual repetition resource. Also, when the set of OFDM symbols constituting the certain nominal repetition includes downlink symbols and symbols other than the downlink symbols by the second TDD pattern configuration, the resource constituted by the symbols other than the downlink symbols may be configured as the actual repetition resource.

Also, when the set of OFDM symbols constituting the certain nominal repetition by the first TDD pattern configuration includes downlink symbols and symbols other than the downlink symbols, the resource constituted by the symbols other than the downlink symbols may be configured as the actual repetition resource.

[0344] For example, when a first TDD pattern configuration and a second TDD pattern configuration are provided to the terminal device 1 and a second PUSCH repetition type is applied to a PUSCH transmitted together with a PRACH in message A of the fourth random access procedure, the actual repetition resource for the PUSCH may be determined by referring to the first TDD pattern configuration.
