[0020] As shown in FIG. 2, the embodiment of the present application is The terminal includes a step 201 of performing a physical layer operation based on a first SSB when a first downlink bandwidth portion BWP includes a first synchronization signal / physical broadcast channel signal block SSB including a non-cell-defined SSB; The physical layer operation includes: The operation of the first term is to determine the energy per resource element (EPRE) of a downlink Channel State Information Reference Signal (CSI-RS); The operation of the second term is to determine an associated operation for a Physical Downlink Control Channel (PDCCH) candidate resource; 3. changing the transmission direction corresponding to the flexible slot by a dynamic slot format indicator (SFI); 4. determining an available Physical Random Access Channel (PRACH) opportunity or a Physical Uplink Shared Channel (PUSCH) opportunity; 5.

[0021] The terminal in the embodiment of the present application may be a reduced capability terminal (RedCap device / UE or reduced capability terminal) or a conventional terminal, i.e., a non-reduced capability terminal.

[0022] It should be noted that the method of the embodiment of the present application can also be applied to the flexible / full duplex and multiple TRP scenarios of release-18 (Rel-18).

[0023] In an embodiment of the present application, when a first SSB including a non-cell-defined SSB is included in a first downlink bandwidth part (BWP), the terminal performs a physical layer operation based on the first SSB, the physical layer operation including at least one of: determining an EPRE of a downlink channel state information reference signal (CSI Reference Signal, CSI-RS); determining an associated operation for a PDCCH candidate resource; changing a transmission direction corresponding to a flexible slot according to an SFI; determining an effective PRACH opportunity; scheduling repeated transmission according to an RAR UL grant or a first DCI; determining a correspondence between an HARQ process number and a plurality of scheduled PUSCH transmissions; determining a first condition for triggering a delay in transmission of an SPS HARQ-ACK in a first slot; determining a second condition for delaying transmission of the SPS HARQ-ACK to a second slot; and evaluating radio link quality or evaluating link recovery quality in each indication period. In the embodiment of the present application, it is clear that the above physical layer operation is completed based on the first SSB, which includes a non-cell-defined SSB, and the network side can correspondingly configure the first SSB according to the physical layer operation.

[0024] Optionally, with respect to the operation of paragraph 1 above, the terminal determining the energy E P RE of each resource element of the downlink CSI-RS based on the first SSB; This includes determining the EPRE based on a power offset parameter for the target first SSB of the CSI-RS and a synchronization signal block power (SS-PBCH-Block Power) set by a higher layer.

[0025] Specifically, the EPRE is obtained by adding or subtracting a value corresponding to the synchronization signal block power and the power offset parameter.

[0026] Selectable, the target 1st SSB is A first SSB included in the first BWP; The first SSB, as set or assigned by the network; one of the first SSBs having the same target parameters as the second SSB; The target parameters include at least one of a synchronization signal block power (SS-PBCH-Block Power) and a physical cell identifier (PCI), and the second SSB includes a cell defining SSB (CD-SSB).

[0027] Optionally, with respect to the operation of paragraph 2 above, the terminal determining a related operation on PDCCH candidate resources based on the first SSB; When a resource element corresponding to a PDCCH candidate resource overlaps with a resource element corresponding to the first SSB, the terminal performs a first operation, the first operation including: not monitoring the PDCCH candidate resources; monitoring the PDCCH candidate resources or not receiving the first SSB; and determining that configuration or scheduling by the network is incorrect.

[0028] The PDCCH candidate resources include a PDCCH potential search space. If at least one resource element of the PDCCH candidate resources of the terminal overlaps with at least one RE in which the first SSB is located, the terminal performs the first operation.

[0029] Here, when the resource elements corresponding to the PDCCH candidate resources overlap with the resource elements corresponding to the first SSB, not monitoring the PDCCH candidate resources ensures reception of the SSB, and helps the terminal to accurately determine the time and accurately estimate the measurement channel quality through the measurement of the SSB. Also, not monitoring the PDCCH candidate resources allows the network scheduling to be unrestricted, and resource collision between the PDCCH candidate resources scheduled by the network and the first SSB is allowed.

[0030] Here, when resource elements corresponding to PDCCH candidate resources overlap with resource elements corresponding to the first SSB, by not receiving the first SSB, it is possible to prioritize reception of the PDCCH and reduce loss or delay of data or control signals; and by not receiving the first SSB, it is possible to not restrict network scheduling, and resource collisions between the PDCCH candidate resources scheduled by the network and the first SSB are permitted.

[0031] Optionally, with respect to the operation of the above paragraph 3, the terminal changing the transmission direction corresponding to the flexible slot by the dynamic slot format indicator SFI based on the first SSB includes: When detecting a second DCI having a first Slot Format Indicator (SFI) index field value, the terminal discards reception of the first SSB, or receives the first SSB, or determines the operation of the terminal according to the implementation of the terminal. Here, receiving the first SSB helps the terminal to accurately determine the time and estimate the accurate measured channel quality by measuring the SSB, and discarding reception of the first SSB determines the flexibility of the network to change the transmission direction and helps save power in the terminal. Alternatively, the terminal determines that it does not want a second DCI having a first SFI index field value to be detected.

[0032] Optionally, the fact that the terminal does not want the second DCI having the above-mentioned first SFI index field value to be detected may be understood to mean that the base station cannot transmit the second DCI having the first SFI index field value to the terminal, or that if the base station transmits the second DCI having the first SFI index field value to the terminal, the operation of the terminal will be unclear.

[0033] Here, the first SFI index field value indicates that the transmission direction corresponding to the first symbol is an uplink transmission direction, and the first symbol is at least one symbol among the symbols corresponding to the first SSB.

[0034] Here, if the first terminal does not want DCI format 2_0 (i.e., the second DCI) having the first SFI index field value to be detected for a set of symbols in which the first SSB exists, and if the first terminal detects that any symbol in the set of symbols indicated by this value is an uplink, or any symbol in the set of symbols indicated by DCI format 2_0 having the first SFI index field value is an uplink, the first terminal discards reception of the first SSB, or the operation of the first terminal depends on the implementation by the terminal, or the first terminal receives the first SSB.

[0035] Optionally, with respect to the operation of paragraph 4 above, the terminal determining a valid PRACH opportunity or a physical uplink shared channel (PUSCH opportunity) based on the first SSB, determining a first opportunity that is after the third SSB and / or the fourth SSB and has a distance from the fourth SSB that is greater than a first distance as a valid first opportunity, the first opportunity including at least one of a PRACH opportunity and a PUSCH opportunity; The third SSB is a first SSB in a slot in which a PRACH or a PUSCH is located, or is a first SSB set or designated by a network, and the fourth SSB is a first SSB, or is a first SSB set or designated by a network; Alternatively, the third SSB is a second SSB in a slot in which a PRACH or a PUSCH is located, and the fourth SSB is a first SSB or a first SSB set or designated by a network; Alternatively, the third SSB is a first SSB in a slot in which a PRACH or a PUSCH is located, or is a first SSB set or designated by a network, and the fourth SSB is a second SSB; The second SSB is a cell-defined SSB.

[0036] In one possible implementation, the fourth SSB is the last first SSB in the first slot, or a first SSB configured or specified by the network, the first slot being the slot in which the first opportunity occurs, or a slot prior to the slot in which the first opportunity occurs, e.g., the fourth SSB is located in the last few symbols in slot n, and the PRACH opportunity is located in the previous few symbols in slot n+1. The fourth SSB and the third SSB may be the same SSB or different SSBs.

[0037] In an embodiment of the present application, the first interval includes M symbols, where M may be specified in a protocol or set by the network.

[0038] In relation to this clause 4, in a symmetric or paired spectrum, a terminal that does not have full-duplex capability determines a valid physical random access channel PRACH opportunity, and in an asymmetric or unpaired spectrum, a half-duplex terminal determines a valid physical random access channel PRACH opportunity, and in a flexible spectrum or full-duplex spectrum, a half-duplex / full-duplex or flexible-duplex terminal determines a valid physical random access channel PRACH opportunity.

[0039] As a first type of implementation of an embodiment of the present application, for an asymmetric spectrum, if a PRACH opportunity (or PRACH resource) is not located before the third SSB in the slot in which the PRACH exists (it may overlap with the third SSB), and is after the fourth SSB in the slot in which the PRACH exists, and the interval between the fourth SSB and the PRACH opportunity is greater than a first interval, the PRACH opportunity is determined to be a valid PRACH opportunity.

[0040] In a second type of realization of the embodiment of the present application, if a PUSCH opportunity for two-step random access and scheduling grant in a Radio Resource Control (RRC) idle or inactive state is not located before the third SSB in a slot in which a PUSCH exists (it may overlap with the third SSB), and is after the fourth SSB in a slot in which a PUSCH opportunity exists, and the interval between the fourth SSB and the PUSCH opportunity is greater than the first interval, the PUSCH opportunity is determined to be a valid PUSCH opportunity.

[0041] Optionally, in an embodiment of the present application, before the terminal determines a valid PRACH opportunity based on a first SSB, the method further comprises: The method further includes the step of: the terminal performing a second operation, the second operation including: When target information is set in an uplink BWP associated with a first downlink BWP or when the terminal is in a connected state, determining that the third SSB is a first SSB in a slot in which the PRACH or PUSCH is located, and / or determining that the fourth SSB is a first SSB; and determining, when the terminal is in a connected state, that at least one of the third SSB and the fourth SSB is a first SSB configured or designated by a network; The target information is Dedicated random access channel configuration information, Common random access channel setting information, Beam failure recovery setting information, The physical uplink shared channel setting information includes at least one of the physical uplink shared channel setting information related to the two-step random access.

[0042] With respect to the operation of paragraph 5, the terminal schedules repeated transmission by using an uplink grant (RAR UL grant) or a first downlink control information (DCI) of a random access response based on a first SSB; When a resource corresponding to the N-th repeated transmission overlaps with a resource corresponding to the first SSB, the terminal performs a third operation, where N is a positive integer, and the third operation includes: delaying said Nth repeated transmission; discarding the Nth repeated transmission; and performing the N-th repeated transmission; determining that the network configuration or network scheduling is incorrect; The repeated transmission includes repeated transmission of a PUSCH or repeated transmission of a PUCCH.

[0043] With respect to the operation of paragraph 6, the terminal determines a correspondence between the HARQ process number and a plurality of scheduled PUSCH transmissions based on the first SSB, When the terminal is scheduled for a plurality of PUSCH transmissions by a third DCI, the HARQ process number indicated by the third DCI is associated with a first PUSCH transmission that does not overlap with a second symbol, and the second symbol is A downlink symbol indicated in a time division duplex uplink-downlink common configuration or a time division duplex uplink-downlink dedicated configuration; At least one of the symbols corresponding to the first SSB is included.

[0044] Optionally, the method of the present application includes: The method further includes determining a process number of the subsequent PUDCH transmission according to a scheduling order of subsequent PUSCH transmissions after the first PUSCH transmission and a HARQ process number of the first PUSCH transmission.

[0045] Optionally, determining a process number of the subsequent PUSCH transmission according to a scheduling order of the subsequent PUSCH transmission after the first PUSCH transmission and a HARQ process number of the first PUSCH transmission, If a symbol corresponding to the subsequent PUSCH transmission does not overlap with the second symbol, determining a process number of the subsequent PUSCH transmission according to a scheduling order of the subsequent PUSCH transmission and a HARQ process number of the first PUSCH.

[0046] In an embodiment of the present application, when a UE is scheduled to transmit multiple PUSCHs by a DCI (the above-mentioned third DCI), the HARQ process ID indicated by the DCI is applied to the first PUSCH that does not overlap with the downlink symbol indicated by the TDD-UL-DL-Configuration Common or TDD-UL-DL-Configuration Dedicated, or is applied to the first PUSCH that does not overlap with any symbol corresponding to the first SSB. Then, for each subsequent PUSCH according to the scheduling order, the HARQ process ID is incremented by one, and the total number of HARQ process numbers (nrofHARQ-ProcessesForPUSCH) of PUSCHs is multiplied by one. If at least one of the symbols in a slot in which a PUSCH transmission exists, as indicated by an index row of the resource allocation table, overlaps with a Downlink (DL) symbol or a symbol in which the first SSB exists, as indicated by the Tdd-UL-DL-ConfigurationCommon or Tdd-UL-DL-ConfigurationDedicated, the HARQ process ID is not incremented for this non-transmitted PUSCH.

[0047] With respect to the operation of paragraph 7, the first condition is: The method includes: in a first slot, a PUCCH for transmitting an SPS HARQ-ACK is indicated by a first parameter; and a symbol corresponding to the PUCCH overlaps with a symbol corresponding to the first SSB.

[0048] Here, the first parameter includes at least one of a PUCCH resource list (set) fed back by semi-persistent scheduling (HARQ) and a PUCCH resource fed back by semi-persistent scheduling (HARQ).

[0049] In an embodiment of the present application, in the first slot, when the PUCCH transmitting the SPS HARQ-ACK is provided by the PUCCH resource list (SPS-PUCCH-AN-List) fed back by the semi-persistent scheduling HARQ or the PUCCH resource (n1PUCCH-AN) parameter fed back by the semi-persistent scheduling HARQ, and the PUCCH overlaps with the symbol where the first SSB exists by at least one symbol, a delay of the transmission procedure of the SPS HARQ-ACK is triggered.

[0050] With respect to the operation of paragraph 8, the second condition is: The method further includes a method in which a symbol corresponding to a PUCCH carrying an SPS HARQ-ACK indicated by a first parameter and transmitted with a delay in a second slot does not overlap with a symbol corresponding to the first SSB.

[0051] In an embodiment of the present application, if the PUCCH carrying the delayed SPS HARQ-ACK provided by the SPS-PUCCH-AN-List or n1PUCCH-AN parameter in the second slot does not completely overlap with the existing symbol of the first SSB, it can be determined that the second slot is the slot used to transmit the delayed SPS HARQ-ACK.

[0052] Optionally, for operation 9, the indicated period is the maximum of the shortest period of the first SSB and a predetermined time length.

[0053] Specifically, the predetermined time length may be 10 ms.

[0054] In an embodiment of the present application, the physical layer of the first terminal uses the first SSB to evaluate the radio link quality or link recovery quality once in each indication period, where the first terminal determines the radio link monitoring resource, i.e., the shortest period of the first SSB and the maximum value among 10 milliseconds, as the indication period.

[0055] Optionally, in an embodiment of the present application, the non-cell defined SSB includes at least one of the following: SSB configured by UE-dedicated RRC signalling. SSBs configured by BWP downlink dedicated signaling (BWP-Downlink Dedicated). The SSBs configured by the BWP downlink dedicated signaling may include SSBs configured by the ssb-PositionsInBurst parameter in the BWP downlink dedicated signaling. An SSB configured by a radio resource control (RRC) parameter related to a non-cell defining SSB configuration (e.g., Non Cell Defining SSB). An SSB that is not used to acquire System Information Block 1 (SIB1) of the current serving cell or an SSB that is not used to acquire SIB1 corresponding to the PDCCH setting of the current serving cell.

[0056] In an embodiment of the present application, when the first downlink bandwidth portion BWP includes a first SSB including a non-cell-defined SSB, the terminal performs a physical layer operation based on the first SSB, and the physical layer operation includes at least one of: determining an EPRE of a downlink CSI-RS; determining an associated operation on a PDCCH candidate resource; changing a transmission direction corresponding to a flexible slot according to an SFI; determining an available PRACH opportunity; scheduling repeated transmission according to an RAR UL grant or a first DCI; determining a correspondence between an HARQ process number and a plurality of scheduled PUSCH transmissions; determining a first condition for triggering a delay in transmission of an SPS HARQ-ACK in the first slot; determining a second condition for delaying transmission of the SPS HARQ-ACK to a second slot; and evaluating radio link quality or evaluating link recovery quality in each indication period. In the embodiment of the present application, it is clear that the above physical layer operation is completed based on the first SSB, which includes a non-cell-defined SSB, and the network side can correspondingly configure the first SSB according to the physical layer operation.

[0057] In one embodiment of the present application, the first terminal (UE1) has a currently activated BWP as BWP#1, and the first SSB (including NCD-SSB) is configured by the network, and the second terminal (UE2) has a currently activated BWP as BWP#2, and only CD-SSB is configured by the network for BWP#2. UE2 only sees CD-SSB, but from the network's point of view, BWP#2 actually includes CD-SSB and NCD-SSB, as shown in FIG. 3. For UE1, the following is true:

[0058] In one embodiment of the present application, UE1 is a half-duplex (HD) UE in paired spectrum, and when the HD-UE transmits PUSCH, PUCCH, or Sounding Reference Signal (SRS) based on higher layer configuration, and the presence of SS / PBCH blocks in the HD-UE's active BWP is indicated by ssb-PositionsInBurst in SIB1 or ServingCellConfigCommon, or by NonCellDefiningSSB, the HD-UE does not transmit: PUSCH or PUCCH. The last symbol of a PUSCH or PUCCH transmission must be at least N symbols after the first symbol of the next earliest SS / PBCH block. Tx-Rx T c [4, TS 38.211]. PUSCH or PUCCH. The first symbol of a PUSCH or PUCCH transmission is the last symbol N of the previous closest SS / PBCH block. Rx-Tx T c [4, TS 38.211]. SRS. The symbol containing the SRS transmission must be at least N symbols after the first symbol of the next earliest SS / PBCH block. Tx-Rx T c If it is not located before. SRS. The symbol containing the SRS transmission is the last symbol N of the SS / PBCH block immediately preceding the symbol Rx-Tx T c It is not located after

[0059] N Tx-Rx T c and N Rx-Tx T c It should be explained that these have the same meaning as conventional parameters.

[0060] If the HD-UE transmits PRACH based on the detected DCI format, and transmits PUSCH, PUCCH or SRS, and the ssb-PositionsInBurst in SIB1 or ServingCellConfigCommon or the NonCellDefiningSSB indicates that an SS / PBCH block is present in a set of symbols (symbol set) of the HD-UE's active BWP, then if an uplink transmission overlaps with any symbol in the symbol set, the HD-UE does not transmit PUSCH, PUCCH or PRACH, and the HD-UE does not transmit SRS in that symbol set.

[0061] When an HD-UE transmits a PRACH or MsgA PUSCH triggered by higher layers in a set of symbols and receives a PDCCH or PDSCH or CSI-RS or a Downlink Positioning Reference Signal (DL PRS), or the presence of an SS / PBCH block in a set of symbols (symbol set) of the active BWP is indicated by ssb-PositionsInBurst in SIB1 or ServingCellConfigCommon or by NonCellDefiningSSB, the HD-UE can select whether to transmit a PRACH, transmit an MsgA PUSCH, or receive a PDSCH or CSI-RS or DL ​​PRS or PDCCH or an SS / PBCH block according to its implementation.

[0062] When the HD-UE receives a PDCCH, a PDSCH, a CSI-RS, or a DL PRS based on a configuration of higher layers, or when the ssb-PositionsInBurst in SIB1 or ServingCellConfigCommon or NonCellDefiningSSB indicates that an SS / PBCH block exists in a set of symbols (symbol set) of an active BWP, and the HD-UE transmits a PRACH or MsgA PUSCH triggered by higher layers, the start or end symbol of the PRACH transmission is N from the last or first symbol in the symbol set, respectively. Rx-Tx T c Or N Tx-Rx T c If it is earlier or later than this, the HD-UE can choose to transmit a PRACH, transmit a MsgA PUSCH, or receive a PDSCH or CSI-RS or DL ​​PRS or PDCCH or SS / PBCH block depending on its implementation.

[0063] In one embodiment of the present application, the UE's monitoring of PDCCH candidates can be achieved by the following method.

[0064] Method 1: Regarding monitoring of PDCCH candidates by the UE, the UE: ssb-PositionsInBurst for the serving cell has already been received, Do not monitor PDCCH candidates in the Type0-PDCCH CSS set, If at least one RE for a PDCCH candidate overlaps with at least one RE of the RE in which the candidate SS / PBCH block corresponding to the SS / PBCH block index provided by ssb-PositionsInBurst resides, the UE does not need to monitor the PDCCH candidate.

[0065] Method 2: Regarding monitoring of PDCCH candidates by the UE, the UE: ssb-PositionsInBurst has been received in the ServingCellConfigCommon and / or NonCellDefiningSSB of the serving cell, Do not monitor PDCCH candidates in the Type0-PDCCH CSS set, If at least one RE of a PDCCH candidate overlaps with at least one RE of an RE in which a candidate SS / PBCH block of the SS / PBCH block index exists and the SS / PBCH block index is provided by ssb-PositionsInBurst and / or NonCellDefiningSSB (if this parameter is provided) in ServingCellConfigCommon, the UE does not need to monitor the PDCCH candidate.

[0066] In one embodiment of the present application, for a set of symbols in a slot corresponding to an SS / PBCH block, the candidate SS / PBCH block index corresponds to the SS / PBCH block index indicated to the UE by ssb-PositionsInBurst in SIB1 or ssb-PositionsInBurst in ServingCellConfigCommon or NonCellDefiningSSB, and the UE does not want to detect DCI format 2_0 with an SFI-index field value, which indicates that the set of symbols in the slot are uplink.

[0067] In one embodiment of the present application, the candidate SS / PBCH block index of the SS / PBCH block corresponds to the SS / PBCH block index provided by ssb-PositionsInBurst or ServingCellConfigCommon in SIB1, or is provided by NonCellDefiningSSB, for details, see the description of the related protocol.

[0068] In one embodiment of the present application, a PUSCH opportunity is valid if it does not overlap in time and frequency with any valid PRACH opportunity associated with a Type-1 random access procedure or a Type-2 random access procedure. For non-paired spectrum and SS / PBCH blocks with indexes provided by ssb-PositionsInBurst or ServingCellConfigCommon or NonCellDefiningSSB in SIB1, see the description of the relevant protocol.

[0069] In one embodiment of the present application, the SS / PBCH block symbol is a symbol of an SS / PBCH block having a candidate SS / PBCH block index, and corresponds to the SS / PBCH block index indicated to the UE by ssb-PositionsInBurst in SIB1 or ssb-PositionsInBurst in ServingCellConfigCommon, or the SS / PBCH block index indicated to the UE by NonCellDefiningSSB; for details, see the description of the related protocol.
