[0020] As shown in FIG. 2, the embodiment of the present application The terminal includes a step 201 of performing a physical layer operation based on a first SSB when the first downlink bandwidth portion BWP includes a first synchronization signal / physical broadcast channel signal block SSB including a non-cell-defining SSB; The physical layer operation includes: The first operation determines the energy per resource element (EPRE) of a downlink Channel State Information Reference Signal (CSI-RS); the second operation determining the associated operation for the Physical Downlink Control Channel (PDCCH) candidate resources; The operation of item 3 is to change the transmission direction corresponding to the flexible slot by a dynamic slot format indicator (SFI); 4. determining valid Physical Random Access Channel (PRACH) or Physical Uplink Shared Channel (PUSCH) opportunities; 5. scheduling repeated transmissions using a first Downlink Control Information (DCI) scrambled by an Uplink grant (UL grant) of a Random Access Response (RAR) or a Temporary Cell Radio Network Temporary Identifier (TC-RNTI); 6.

[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-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 relationship between HARQ process numbers and multiple 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 until the second slot, and evaluating radio link quality or 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, including the 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 the first paragraph, the terminal determining the energy E PRE 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 the synchronization signal block power (SS-PBCH-Block Power) set by higher layers.

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

[0026] Selectable, target 1st SSB, a first SSB included in the first BWP; The first SSB, as set or designated 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 for PDCCH candidate resources based on the first SSB includes: 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, wherein the first operation includes: not monitoring the PDCCH candidate resources; monitoring the PDCCH candidate resources or not receiving the first SSB; and determining that the 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 resource elements corresponding to PDCCH candidate resources overlap with resource elements corresponding to the first SSB, not monitoring the PDCCH candidate resources ensures reception of the SSB and helps the terminal accurately determine the time and accurately estimate the measurement channel quality by measuring the SSB. Also, not monitoring the PDCCH candidate resources allows the network to unrestrict scheduling and allows resource collision between the PDCCH candidate resources scheduled by the network and the first SSB.

[0030] Here, when the resource elements corresponding to the PDCCH candidate resources overlap with the resource elements corresponding to the first SSB, not receiving the first SSB allows the reception of the PDCCH to be prioritized, thereby reducing the loss and delay of data or control signals; not receiving the first SSB also allows the network scheduling to be unrestricted, 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 third paragraph above, 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, receives the first SSB, or determines the terminal's behavior depending on the terminal's implementation. Here, receiving the first SSB helps the terminal accurately determine time and accurately estimate measurement 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 as meaning 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., 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 will discard reception of the first SSB, or the operation of the first terminal will depend on the implementation by the terminal, or the first terminal will receive 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 may include: determining a first opportunity that is later than the third SSB and / or the fourth SSB and has an interval from the fourth SSB that is greater than a first interval as a valid first opportunity, wherein the first opportunity includes 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 alternative implementation, the fourth SSB is the last first SSB in the first slot, or is a first SSB configured or designated by the network, and the first slot is 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 this paragraph 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; in an asymmetric or unpaired spectrum, a half-duplex terminal determines a valid physical random access channel PRACH opportunity; and in a flexible or full-duplex spectrum, a half-duplex / full-duplex or flexible-duplex terminal determines a valid physical random access channel PRACH opportunity.

[0039] In a first implementation of the 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 located 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 implementation 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 located 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, then the PUSCH opportunity is determined to be a valid PUSCH opportunity.

[0041] Optionally, in an embodiment of the present application, before the step of the terminal determining a valid PRACH opportunity based on the first SSB, the method further comprises: The method further includes the step of the terminal performing a second operation, wherein the second operation includes: 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 the first SSB in a slot in which the PRACH or PUSCH is located and / or determining that the fourth SSB is the 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 configuration information, Beam failure recovery setting information, The physical uplink shared channel configuration information includes at least one of physical uplink shared channel configuration information related to two-step random access.

[0042] With respect to the operation of paragraph 5, the terminal scheduling repeated transmission by using a random access response uplink grant (RAR UL grant) or first downlink control information (DCI) based on the 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 the Nth repeated transmission; discarding the Nth repeated transmission; performing the Nth repeated transmission; determining that the network configuration or the network scheduling is incorrect; The repeated transmission includes repeated transmission of a PUSCH or repeated transmission of a PUCCH.

[0043] Regarding the operation of paragraph 6, the terminal determining a correspondence between an HARQ process number and a plurality of PUSCH transmissions to be scheduled 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 Downlink symbols indicated in a time division duplex uplink-downlink common configuration or a time division duplex uplink-downlink dedicated configuration; It includes at least one of the symbols corresponding to the first SSB.

[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.

[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 includes: If the symbol corresponding to the subsequent PUSCH transmission does not overlap with the second symbol, determining a process number of the subsequent PUDCH 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 third DCI), the HARQ process ID indicated by the DCI is applied to the first PUSCH that does not overlap with a downlink symbol indicated in the TDD-UL-DL configuration (common) or TDD-UL-DL configuration (dedicated), or the first PUSCH that does not overlap with any symbol corresponding to the first SSB. Then, for each subsequent PUSCH in the scheduling order, the HARQ process ID is incremented by one, and a joint arithmetic operation is performed on the total number of HARQ process numbers for the PUSCHs (nr of HARQ-ProcessesForPUSCH). If at least one of the symbols in a slot where a PUSCH transmission exists, as indicated by an index row of the resource allocation table, overlaps with a downlink (DL) symbol or a symbol where the first SSB exists, as indicated by 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: a PUCCH carrying an SPS HARQ-ACK in a first slot 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, when the PUCCH for transmitting the SPS HARQ-ACK in the first slot is provided by the PUCCH resource list (SPS-PUCCH-AN-List) fed back by semi-persistent scheduling HARQ or the PUCCH resource (n1PUCCH-AN) parameter fed back by semi-persistent scheduling HARQ, and the PUCCH overlaps with the existing symbol of the first SSB 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 symbol corresponding to the PUCCH carrying the SPS HARQ-ACK indicated by the first parameter and transmitted with a delay in the second slot does not overlap with the symbol corresponding to the first SSB.

[0051] In an embodiment of the present application, if the PUCCH in the second slot provided by the SPS-PUCCH-AN-List or n1PUCCH-AN parameter and carrying the delayed SPS HARQ-ACK 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 the operation of item 9, the indicated period is the maximum value between 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, and 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 signaling. 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 positions in burst set (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 configuration 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, where 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 relationship between HARQ process numbers and multiple 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 until the second slot; and evaluating radio link quality or 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, including the non-cell-defined SSB, and the network side can correspondingly configure the first SSB according to the physical layer operation.
