For example, for a terminal with some reduced capabilities (RedCap UE), the processing time for completing the communication operation related to access can be lengthened based on the relaxed processing function, thereby reducing the complexity and cost of the terminal and improving the reliability of terminal access.

[0031] In an optional embodiment, the relaxed processing function is: The relaxed processing capability includes at least one of an uplink relaxed processing capability, a downlink relaxed processing capability, and a channel state information (CSI) relaxed processing capability.

[0032] The relaxed processing capability of the uplink refers to relaxing the processing time for processing uplink transmissions by a terminal, for example, the processing time for processing a Physical Uplink Shared Channel (PUSCH) by a terminal, or the processing time for processing a Physical Uplink Control Channel (PUCCH) by a terminal.

Note that the relaxed CSI processing capability can indicate whether the CSI relaxed processing / calculation capability is supported by the terminal UE by CSI processing type 3 (csi-ProcessingType3) or CSI calculation type 3 (csi-ComputationType3).

[0035] Optionally, the downlink relaxed processing capability comprises: Includes relaxed processing capabilities for PDSCH, Here, the number of PDSCHs supported or processed by the terminal within the target period based on the relaxed processing capabilities of the PDSCH is N, the PDSCH is a PDSCH carrying multiple different transport blocks scrambled using a Radio Network Temporary Identifier (RNTI), and N is an integer greater than or equal to 1.

[0036] The relaxed processing capability of the PDSCH can indicate whether the relaxed processing capability of the PDSCH is supported by the terminal through PDSCH processing type 3 (PDSCH-ProcessingType3).

[0037] The target period may be one time resource unit, for example one time slot.

[0038] The above RNTI is The identifier may include at least one of a Cell Network Temporary Identifier (C-RNTI), a Modulation and Coding Scheme Cell-Radio Network Temporary Identifier (MCS-C-RNTI), a Configured Scheduling Network Temporary Identifier (CS-RNTI), and a temporary cell-radio network temporary identifier (TC-RNTI).

[0039] The above item, in which N is the number of PDSCHs supported or processed by the terminal within a target period based on the relaxed processing capabilities of the PDSCH, may be indicated by a different transport block (pdsch-ProcessingType3-DifferentTB-PerSlot) corresponding to each time slot of PDSCH processing type 3, for example, indicating the number of PDSCHs carrying different transport blocks scrambled using C-RNTI, TC-RNTI, or CS-RNTI that can be supported or processed by the terminal within one target period (preferably, the target period is one time slot) of one carrier / bandwidth part (BWP) with a relaxed processing time, and the number may be It may be at least one of 1, 2, 4, and 7.

[0040] In this embodiment, the processing performance of the terminal for processing the PDSCH can be improved.

[0041] Optionally, the uplink relaxed processing functionality comprises: Includes relaxed processing capabilities for PUSCH, Here, the number of PUSCHs supported or processed by the terminal within the target period based on the relaxed processing capability of the PUSCH is M, the PUSCH is a PUSCH carrying multiple different transport blocks scrambled using RNTI, and M is an integer greater than or equal to 1.

[0042] The relaxed processing capability of the PUSCH can indicate whether the relaxed processing capability of the PUSCH is supported by the terminal through PUSCH processing type 3 (PUSCH-ProcessingType3).

[0043] The above RNTI is It may include at least one of a C-RNTI, an MCS-C-RNTI, a CS-RNTI, and a TC-RNTI.

[0044] The above item that the number of PUSCHs supported or processed by the terminal within a target period based on the relaxed processing capability of the PUSCH is M may be indicated by a different transport block (pusch-ProcessingType3-DifferentTB-PerSlot) corresponding to each time slot of PUSCH processing type 3, for example, indicating the number of PUSCHs carrying different transport blocks scrambled using C-RNTI, TC-RNTI, or CS-RNTI that can be supported or processed by the terminal within one target period (preferably, the target period is one time slot) of one carrier / BWP with a relaxed processing time, and the number may be It may be at least one of 1, 2, 4, and 7.

[0045] Optionally, the relaxed processing function comprises: separately configuring relaxed processing capabilities for the uplink; separately configuring the relaxed processing function of the downlink; Separately setting a relaxed processing function for the CSI; and jointly / commonly configuring the uplink relaxed processing function and the downlink relaxed processing function; The relaxed processing function for the uplink, the relaxed processing function for the downlink, and the relaxed processing function for the CSI are configured in at least one of the following ways: jointly / commonly configuring the relaxed processing function for the uplink, the relaxed processing function for the downlink, and the relaxed processing function for the CSI.

[0046] As described above, the relaxed processing function for the uplink can be set individually, and the relaxed processing function for the downlink can be set individually, so that the relaxed processing time functions for the uplink and downlink can be set individually, for example, pdsch-ProcessingType3 and pusch-ProcessingType3 can be set individually.

[0047] The above-mentioned relaxed processing function of the uplink and the relaxed processing function of the downlink may be set jointly / commonly, or the relaxed processing function of the uplink and the relaxed processing function of the downlink provided in the terminal may be set jointly or commonly.

[0048] The above-mentioned relaxed processing function of CSI may be set individually by individually setting csi-ProcessingType3 or csi-ComputationType3, for example, by individually setting the relaxed processing function of uplink, the relaxed processing function of downlink, and the relaxed processing function of CSI, or by individually setting the relaxed processing function of CSI, but jointly / commonly setting the relaxed processing function of uplink and the relaxed processing function of downlink.

[0049] The above-mentioned relaxed processing function of the uplink, the relaxed processing function of the downlink, and the relaxed processing function of the CSI may be set jointly / commonly, or the relaxed processing function of the uplink, the relaxed processing function of the downlink, and the relaxed processing function of the CSI provided in the terminal may be set jointly or commonly.

[0050] In some embodiments, the relaxed processing function of the uplink and the relaxed processing function of the CSI may be jointly / commonly configured, or the relaxed processing function of the downlink and the relaxed processing function of the CSI may be jointly / commonly configured.

[0051] In this embodiment, the above setting method allows the corresponding relaxed processing functions to be flexibly set for the terminal, thereby improving the processing functions of the terminal.

[0052] Optionally, when the relaxed processing function is set in the terminal, a target characteristic is further set in the terminal, and the target characteristic is: Supporting a maximum bandwidth less than or equal to a pre-set bandwidth threshold; and the data rate is equal to or less than a preset rate threshold.

[0053] The preset bandwidth value may be, but is not limited to, 5 MHz or other bandwidth thresholds defined by protocols. Supporting the above maximum bandwidth to be equal to or less than the preset bandwidth threshold can reduce the bandwidth requirements of terminals, thereby reducing the complexity and cost of terminals.

[0054] The data rate may include at least one of a terminal reception data rate and a terminal transmission data rate. For example, the data rate being equal to or less than a predetermined rate threshold may refer to the maximum reception data rate supported by the terminal being equal to or less than a predetermined rate threshold and / or the maximum transmission data rate supported by the terminal being equal to or less than a predetermined rate threshold. The predetermined rate threshold may be, but is not limited to, 10 Mbps or other rate thresholds defined by protocols. The data rate being equal to or less than a predetermined rate threshold may reduce the terminal's peak value and reduce the terminal's complexity and cost.

[0055] In this embodiment, relaxed processing functions are set for terminals for which target characteristics are set, thereby improving the access reliability of these terminals.

[0056] In an alternative embodiment, the terminal reports / indicates whether it supports UE processing capability 1, where the processing time of the relaxed processing capability is longer than the processing time of the first processing capability.

[0057] The above report / instruction may be reported or instructed to a network side device.

[0058] In this embodiment, for the terminal, the terminal processing capability 1 is an optional capability, for example, the PDSCH processing time capability 1 and / or the PUSCH processing time capability 1 are optional capabilities, and the terminal can report / indicate whether it supports the terminal processing capability 1 through a user capability.

[0059] Since the terminal reports / indicates whether it supports terminal processing function 1, the network side device can flexibly set corresponding parameters for the terminal according to the processing function of the terminal, thus making it easier to match the terminal parameters with the terminal processing function and improving the terminal processing function.

[0060] In an optional embodiment, when the relaxed processing function is set in the terminal, a first processing function is further set in the terminal; Here, the processing time of the relaxed processing function is longer than the processing time of the first processing function.

[0061] The above items in which the first processing function is set may be configured so that the terminal itself has the first processing function, or the network side device may set the first processing function for the terminal by setting parameters.

[0062] In this embodiment, when the terminal has a first processing function and a relaxed processing function, it is possible to perform communication operations based on the relaxed processing function, thereby reducing the complexity and cost of the terminal and improving the reliability of terminal access.

[0063] In an optional embodiment, the subcarrier spacing (SCS) applied to the relaxed processing function is at least one of a 15KHz SCS, a 30KHz SCS, a 60KHz SCS, and a 120KHz SCS; Here, the PDSCH decoding time in the relaxed processing function varies depending on the SCS, and / or the PUSCH preparation time in the relaxed processing function varies depending on the SCS.

[0064] The above-mentioned matter in which the PDSCH decoding times among the relaxed processing functions are different depending on the SCS may be specified by a protocol or set by the network side so that different SCSs correspond to different PDSCH decoding times, and the above-mentioned matter in which the PUSCH preparation times among the relaxed processing functions are different depending on the SCS may be specified by a protocol or set by the network side so that different SCSs correspond to different PUSCH preparation times.

[0065] In this embodiment, the relaxed processing function is applicable to multiple types of SCS, so that the terminal can relax the processing time for multiple SCSs.

[0066] In some embodiments, for some SCSs, the relaxed processing time due to the relaxed processing function may apply to a normal cyclic prefix (normal CP) and / or an extended cyclic prefix (extended CP), e.g., for a 60 KHz SCS, the relaxed processing time applies to a normal cyclic prefix and / or an extended cyclic prefix.

[0067] In an alternative embodiment, for the relaxed processing capabilities, the terminal needs to report / indicate by terminal capabilities that it supports the relaxed processing capabilities, or For the relaxed processing function, the terminal reports / indicates whether the relaxed processing function is supported by the terminal through a terminal capability; For the relaxed processing capabilities, the terminal does not report / indicate the relaxed processing capabilities.

[0068] Regarding the above matters in which the terminal needs to report / indicate by a terminal function that it supports the relaxed processing function, the relaxed processing function may be an optional function of the terminal, but the terminal may be required to report / indicate by a user function that it supports the relaxed processing function. If the relaxed processing function is an optional function of the terminal, the terminal is a terminal that supports the relaxed processing function.

[0069] Regarding the above matter in which the terminal reports / indicates whether the relaxed processing function is supported by the terminal through a terminal function, the relaxed processing function may be an optional function of the terminal, and the target terminal may be able to report / indicate whether it supports this relaxed processing time function through a user function.

[0070] Regarding the above matter in which the terminal does not report / indicate the relaxed processing function, the relaxed processing function is an optional function of the terminal and is not a user function related to the definition of the terminal, i.e., the terminal may not report / indicate the function (optional without capability signaling).

[0071] In an optional embodiment, the communication operations associated with the initial access described above include: an uplink transmission in an initial access process; and downlink reception in an initial access process; The communication operations related to the random access are as follows: uplink transmission in a random access process; and downlink reception in a random access process.

[0072] In this embodiment, it is possible to reduce the processing time of at least one of uplink transmission in the initial access process, downlink reception in the initial access process, uplink transmission in the random access process, and downlink reception in the random access process.

[0073] In an optional embodiment, the step of the terminal performing a communication operation based on a relaxed processing time function comprises: The method includes a step of the terminal performing a communication operation based on relaxed processing capabilities when a first condition is satisfied; Here, the first condition is: The network side device sets / enables / instructs the terminal to BWP; The network side device configures / enables / instructs the terminal to use a common search space (CSS); A network side device configures / enables / instructs the terminal to enable / perform early identification of the terminal via a Physical Random Access Channel (PRACH); A network side device configures / enables / instructs the terminal to enable / perform early identification of the terminal via a PUSCH; The bandwidth of the initial BWP exceeds the maximum bandwidth capability of the baseband side of the terminal; The bandwidth of the control resource set set by the Master Information Block (MIB) exceeds the maximum bandwidth capability of the baseband side of the terminal; The bandwidth occupied by the scheduled / configured downlink reception frequency domain resource exceeds the maximum bandwidth capability of the baseband side (baseband, BB) of the terminal; The bandwidth occupied by the frequency domain resources of the scheduled / configured uplink transmission exceeds the maximum bandwidth capability of the baseband side of the terminal.

[0074] Here, the BWP initial uplink / downlink BWP sets an independent initial downlink / uplink BWP for the RedCap terminal, for example.

[0075] The CSS may be a Type 0 / 0A / 1 / 2 CSS.

[0076] The PRACH may include a PRACH of message 1 (Msg.1) / message A (Msg.A) in the random access process, and the PUSCH may include a PUSCH of message 1 (Msg.1) / message A (Msg.A) in the random access process.

[0077] Regarding the above-mentioned early identification, the type of the terminal can be identified by the network side device in the random access process of the terminal, for example, the type of the terminal may be identified as a RedCap terminal or a general terminal in the random access process.

[0078] The control resource set set by the MIB described above may be a control resource set (CORESET) #0 set by the MIB.

[0079] In this embodiment, the initial DL / UL BWP / CORESET#0 may be an initial DL / UL BWP / CORESET#0 set individually / independently for the terminal, or may be an initial DL / UL BWP / CORESET#0 shared by the terminal and other terminals (e.g., other types of terminals).

[0080] The bandwidth occupied by the frequency domain resources for downlink reception may be a bandwidth obtained by subtracting the minimum PRB index / subcarrier occupied by downlink reception from the maximum physical resource block index / subcarrier (PRB index / subcarrier) occupied by downlink reception, and the bandwidth occupied by the frequency domain resources for uplink transmission may be a bandwidth obtained by subtracting the minimum PRB index / subcarrier occupied by uplink transmission from the maximum physical resource block index / subcarrier (PRB index / subcarrier) occupied by uplink transmission.

[0081] Optionally, the method further comprises: The method further includes the step of the terminal performing the communication operation based on a first processing function if the first condition is not satisfied; Here, the processing time of the relaxed processing function is longer than the processing time of the first processing function.

[0082] In this embodiment, for a terminal in an RRC-idle / inactive state, if the first condition is not met, the terminal may perform uplink transmission and downlink reception using a first processing capability (UE processing capability 1) in the initial access / random access process.

[0083] For example, the network side device sends the following to the target terminal: Separate / Independent Initial DL / UL BWP and Separate / independent Type 0 / 0A / 1 / 2 CSSs, Enabling / performing early identification of the target terminal via Msg.1 / Msg.A PRACH; Enabling / performing early identification of the target terminal via Msg.3 / Msg.A PUSCH; The bandwidth of CORESET#0 set by the initial DL / UL BWP or MIB exceeds the maximum bandwidth capability of the target terminal baseband side; If at least one of the following is configured / enabled / indicated: the bandwidth occupied by the frequency domain resources of the scheduled / configured downlink reception and / or uplink transmission exceeds the maximum bandwidth capability of the target terminal baseband side; then, the relaxed processing function is used to perform uplink transmission and downlink reception; otherwise, the target terminal uses the UE first processing function to perform uplink transmission and downlink reception.

[0084] In an optional embodiment, at least one of an uplink transmission timeline and an uplink transmission timing associated with the communication operation is: The relaxed processing capability is determined.

[0085] The uplink transmission timeline may determine the uplink transmission time or the interval between uplink transmission and downlink reception. The uplink transmission timing may indicate the uplink transmission time, for example, an uplink transmission time slot, a symbol, etc.

[0086] The above uplink transmission timeline / timing can reduce the uplink processing time of the terminal and improve the reliability of the uplink transmission.

[0087] Optionally, when the communication operation includes transmitting a PUSCH with a Random Access Response (RAR) uplink grant, the minimum time between the PDSCH carrying the RAR uplink grant and the PUSCH is determined by the relaxed processing function; and / or When the communication operation includes transmission of a PUSCH scheduled by a fallback RAR, the minimum time between the PDSCH carrying the fallback RAR and the PUSCH is determined by the relaxed processing function.

[0088] Here, the shortest time may be determined by the PDSCH processing time and the PUSCH preparation time, and the PDSCH processing time may be determined by the relaxed processing function and / or the PUSCH preparation time may be determined by the relaxed processing function.

[0089] For example, the terminal determines whether the shortest time between the reception of the last symbol of the PDSCH carrying the RAR UL grant / fallback RAR and the reception of the first symbol of the PUSCH scheduled by the RAR UL grant is N T,1 +N T,2 +m1 ms or more, where N T,1 and N T,2 At least one of the above N is determined by the relaxed processing function, and m is a constant, for example, 0.5. T,1 is the duration of N1 symbols corresponding to the PDSCH processing time for relaxed processing capability (UE processing capability 3) when configuring an additional PDSCH DMRS, and N T,2 is the PUSCH preparation time corresponding to the relaxed processing capability (UE processing capability 3) with a duration of N2 symbols.

[0090] In this embodiment, it is possible to reduce the processing time for the PUSCH.

[0091] Alternatively, when the sizes of the SCS corresponding to the PDSCH and the SCS corresponding to the PUSCH are different, the PDSCH processing time is determined by the relaxed processing function and a first SCS, and / or the PUSCH preparation time is determined by the relaxed processing function and a first SCS; Here, the first SCS is the smaller of the two SCSs corresponding to the PDSCH and PUSCH.

[0092] In this embodiment, when the sizes of the SCSs corresponding to the PDSCH and the PUSCH are different, at least one of the PDSCH processing time and the PUSCH preparation time is determined according to the smaller size of the two SCSs, thereby enabling accurate determination of the shortest time. For example, to determine the minimum time interval between the last symbol of the PDSCH carrying the RAR UL grant and the first symbol of the PUSCH scheduled by the RAR UL grant, the terminal T,1 and N T,2 corresponds to the smaller of the SCS settings corresponding to the PDSCH and the PUSCH.

[0093] Optionally, the communication operation comprises: The method includes transmitting a PUSCH in a time slot n+X, where time slot n is a time slot located when the terminal receives a last symbol of downlink signaling scheduling an uplink transmission, and the value of X is determined by the relaxed processing function, and the PUSCH is PUSCH related to initial access, and a PUSCH related to random access.

[0094] The time slot n is the time slot located when the terminal receives the last symbol of the downlink signaling scheduling the uplink transmission, and thus it is possible to realize that the terminal transmits the PUSCH in time slot n+X.

[0095] Here, the value of X is X=K2, X=K2+Δ, X=K2+Δ+Δ′; where K2 denotes a time slot offset, Δ and Δ' are constants related to the SCS, and the value of at least one of K2, Δ, and Δ' is determined by the relaxed processing function.

[0096] In some embodiments, the value of K2 determined by the relaxed processing function is greater than the value of K2 determined by the first processing function.

[0097] For example, the value of K2 can be shown in Table 1 or Table 2 below, where the definition of the value of j is as shown in Table 3 below.

[0098] [Table 1]

[0099] [Table 2]

[0100] Here, S and L may represent the starting symbol and transmission length of PUSCH transmission, respectively.

[0101] [Table 3]

[0102] Here, the above μ PUSCH may represent the SCS used for the PUSCH.

[0103] Here, PUSCH processing function 1 denotes the first processing function, and the above PUSCH processing function 3 denotes the relaxed processing function, and it is clear that the value of K2 determined by the relaxed processing function is twice the value of K2 determined by the first processing function.

[0104] It should be noted that the above Table 3 is merely illustrative, and the j corresponding to the value of K2 may be n times the j corresponding to the value of K2 determined by the first processing function (for example, n=2, and the value of n is specified by the protocol or set by the network), for example, the values ​​are 2j, 2(j+1), 2(j+2), 2(j+3), and the j corresponding to the value of K2 is = n*j (for example, n=2, and the value of n is specified by the protocol or set by the network), that is, the values ​​are 2j, 2j+1, 2j+2, 2j+3, where the value of j is the value of j corresponding to the first processing function defined by the protocol. For example, as shown in Table 4.

[0105] [Table 4]

[0106] In some embodiments, the value of Δ determined by the relaxed processing function is equal to the value of Δ determined by the first processing function, or the value of Δ determined by the relaxed processing function is greater than the value of Δ determined by the first processing function.

[0107] For example, the definition of the value of Δ may be as shown in Table 5 or Table 6.

[0108] [Table 5]

[0109] [Table 6]

[0110] According to Table 6, it is clear that the Δ determined by the relaxed processing function can be n times (e.g., n=2, where the value of n is specified by the protocol or set by the network) the value of Δ determined by the first processing function, e.g., a value of 2Δ.

[0111] In some embodiments, the value of Δ′ determined by the relaxed processing function is equal to the value of Δ′ determined by the first processing function, or the value of Δ′ determined by the relaxed processing function is greater than the value of Δ′ determined by the first processing function.

[0112] For example, the value of Δ′ may be as shown in Table 7.

[0113] [Table 7]

[0114] In the above embodiment, it is possible to alleviate the time required to transmit the PUSCH and further improve the reliability of access.

[0115] In the above embodiment, when the UE performs uplink transmission using a relaxed processing function and uses a default time domain resource allocation list (pusch-TimeDomainAllocationList) and / or a time domain resource allocation list configured by a PUSCH common configuration (pusch-ConfigCommon), the value of X may be determined by the relaxed processing function. Here, the default time domain resource allocation list may include at least one of Table 1 and Table 2.

[0116] In an embodiment of the present application, a terminal performs communication operations based on relaxed processing functions, where the relaxed processing functions refer to processing functions that are time-relaxed, and the communication operations include at least one of a communication operation related to initial access and a communication operation related to random access. In this way, it is possible to realize that at least one of a communication operation related to initial access and a communication operation related to random access is performed based on processing functions that are time-relaxed, thereby improving the reliability of terminal access.

[0117] In the following, taking an example where the relaxed processing capability is UE processing capability 3, the method for performing communication operations provided in the embodiments of the present application will be described according to several embodiments.

[0118] Example 1 In this embodiment, the following three situations will be mainly taken as examples for explanation.

[0119] In situation 1, when the network configures a separate initial DL BWP for the terminal and a Type 1 CSS is configured in the separate initial DL BWP, that is, when the target terminal needs to monitor downlink signaling scheduling Msg.3 within a Type 1 common search space set to perform random access, the network assumes that the processing time for the terminal to perform downlink reception and uplink transmission related to random access is determined based on UE processing capability 3.

[0120] In situation 2, when the network enables the early identification function for the target terminal, the early identification can at least identify that a relaxed processing time, i.e., UE processing capability 3, is supported by the terminal, and the early identification is carried in Msg. 1. When the terminal initiates random access to the network using Msg. 1 with the early identification function, the network assumes that the processing time for the terminal to perform downlink reception and uplink transmission related to the random access is determined based on UE processing capability 3.

[0121] In situation 3, the capability of the terminal to reduce the maximum bandwidth is defined as reducing the maximum bandwidth capability of the baseband (BB). For example, when the maximum bandwidth capability of the radio frequency (RF) is 20 MHz and the maximum bandwidth capability of the baseband is 5 MHz, if the bandwidth of the initial BWP of the terminal operation exceeds 5 MHz, or the bandwidth occupied by the frequency domain resource where the Type 1 CSS configured for the terminal is located exceeds 5 MHz, or the bandwidth occupied by the frequency domain resource for scheduled uplink transmission or downlink reception exceeds 5 MHz, it is assumed that the network determines the processing time for downlink reception and uplink transmission related to random access by the terminal based on UE processing capability 3.

[0122] Regarding the above situation 1, situation 2 and situation 3, RAR UL grant / fallback PUSCH scheduled by RAR (first transmission of Msg.3) and The terminal uses UE processing capability 3 to prepare for uplink transmission of PUSCH (retransmission of Msg.3) scrambled by TC-RNTI and scheduled by DCI format 0_0.

[0123] Here, in response to feedback of HARQ-ACK after correctly receiving Msg.4 or Msg.B, i.e., in response to receiving a PDSCH with a terminal contention resolution identifier, the terminal transmits HARQ-ACK information on the PUCCH. The minimum time between the last symbol of the PDSCH reception and the first symbol of the corresponding PUCCH transmission carrying the HARQ-ACK information is N T,1 +0.5ms, where N T,1 is the duration of N1 symbols, which corresponds to the PDSCH processing time of UE processing function 3 when configuring an additional PDSCH DM-RS. That is, the terminal determines that the time between the first symbol of PUCCH transmission and the last symbol of the PDSCH reception is N T,1Don't expect it to be smaller than +0.5, where N T,1 is the duration of N1 symbols, which corresponds to the PDSCH processing time of UE processing function 3 when configuring an additional PDSCH DM-RS.

[0124] Example 2 In this embodiment, the example of transmitting PUSCH is mainly taken as an example for description, and specifically may include the following:

[0125] When a UE performs uplink transmission using UE processing capability 3 and the time domain resource assignment (TDRA) used is the default time domain resource assignment list (e.g., Table 1 above), it is assumed that for a PUSCH scheduled by an RAR UL grant / fallback RAR, the SCS of the PDSCH carrying the RAR UL grant / fallback RAR and the SCS of the PUSCH are both 15 kHz.

[0126] In Example 1, if the terminal is located in time slot 1 when it receives the last symbol of the PDSCH carrying the RAR UL grant / fallback RAR and the row index (row index) is specified as 8 by TDRA, the terminal transmits the PUSCH in time slot 1+K2+Δ, where Δ uses the value shown in Table 5 above. For j values ​​as shown in Table 3, 1+(j+1)+Δ=1+(2+1)+2=6; The value of K2 is μ in Table 1 PUSCH = 0, i.e., 15 KHz, and row index = 8, then K2 = 2*(j+1) = 2*(1+1) = 4, where j is as shown in Table 4, i.e., 1 + K2 + Δ = 1 + 4 + 2 = 7, The value of K2 is μ in Table 1 PUSCH= 0 i.e. 15KHz, row index = 8 as shown in the formula, if j is replaced by n*j, then K2 = n*j+1, and if n=2 and the value of j is as shown in Table 4, then 1+K2+Δ = 1+2*j+1 = 1+2*1+1 = 4.

[0127] In example 2, if the terminal is located in time slot 1 when it receives the last symbol of the PDSCH carrying the RAR UL grant / fallback RAR, and the TDRA indicates row index=1, the target terminal will transmit a PUSCH in time slot 1+K2+Δ=1+j+Δ, where j is the value shown for j for PUSCH processing function 3 in Table 3. If the values ​​of Δ are as shown in Table 6, then 1+2+Δ=1+2+4=7, If Δ is n times the value shown in Table 6 (for example, n=1), then 1+2+Δ=1+2+2=5.

[0128] In Example 3, if the terminal is located in time slot 1 when it receives the last symbol of the PDSCH carrying the RAR UL grant / fallback RAR, and the TDRA indicates row index=8, the target terminal will transmit the PUSCH in time slot 1+K2+Δ+Δ′=1+(j+1)+Δ+Δ′, where j is the value shown in Table 3, and Δ is calculated using Table 5, i.e. If Δ' is set by the network and the value of the 15KHz SCS is 0, then 1+K2+Δ+Δ'=1+(2+1)+2+0=6, If Δ' is determined according to Table 7, then 1+K2+Δ+Δ'=1+(2+1)+2+1=7.

[0129] In the embodiment of the present application, the application of relaxed processing time of the terminal in the initial access process and random access process is effectively supported, the implementation cost and complexity of the terminal are reduced, and the network side also supports flexible deployment of the system. For example, if the network side sets an independent initial BWP for the terminal or enables an early identification means, the scheduling of the terminal by the network side will not affect other terminals (e.g., other types of terminals); otherwise, the network can schedule all terminals according to the relaxed time series relationship of the terminals.
