Abstract
Description
Technical Field

[0002] In relevant communication technologies, for users with reduced capability (redcap) terminals (User Equipment, also known as terminal devices or user terminals), since their supported bandwidth is less than or equal to that of ordinary UEs, the network side can configure an additional BWP for the redcap terminal while configuring a bandwidth portion (BWP) for the ordinary UE. This additional BWP ensures that the bandwidth of the additional BWP is within the capability range of the redcap UE. Furthermore, configuring an additional BWP allows for traffic splitting between the redcap terminal's transmissions and those of other terminals, meaning transmissions are performed on different resources. This avoids the problem of excessive load or congestion caused by simultaneous transmissions from ordinary and redcap terminals within the same resource.

[0033] The technical solutions provided in this application will be described in detail below with reference to the accompanying drawings and through some embodiments and application scenarios.
[0034] like Figure 2 The diagram shown is a flowchart of a transmission method 200 provided in an exemplary embodiment of this application. This method 200 can be executed by, but is not limited to, a terminal, specifically by hardware and / or software installed in the terminal. In this embodiment, the method 200 may include at least the following steps.
[0035] S210, the terminal determines the transmission mode of the signal and / or channel on the second BWP based on the transmission configuration information on the first BWP and / or the first SSB set.
[0036] The first BWP can be understood as: a BWP configured by the network side for ordinary terminals, such as an initial uplink BWP or an initial downlink BWP, for transmitting system information blocks (SIBs), physical downlink shared channels (PDSCHs) for paging messages, physical downlink control channels (PDCCHs) for scheduling PDSCHs, etc.
[0037] Accordingly, the second BWP can be understood as an additional BWP configured by the network-side device for the redcap terminal; that is, the second BWP is a BWP configured for the redcap terminal. Furthermore, the second BWP can also be any other BWP besides the aforementioned additional BWP, and this is not limited. In this embodiment, the second BWP may include an uplink BWP and / or a downlink BWP.
[0038] Furthermore, the transmission configuration information on the first BWP may include the channel type, channel / signal transmission timing, etc.
[0039] The SSBs in the first Synchronization Signal and PBCH block set (SSBset) are used for terminal synchronization, system information acquisition, measurement and evaluation, etc. In this embodiment, the first SSBset may include N (N is an integer greater than or equal to 1) SSBs within a preset duration (such as 5ms), and the characteristics of the N SSBs satisfy at least one of the following characteristics (1)-(2).
[0040] (1) Belongs to Cell Definition (CD) - SSB.
[0041] This can be understood as follows: the Physical Broadcast Channel (PBCH) in the SSB contains indication information about the monitoring occasion (MO) of the PDCCH that schedules the SIB.
[0042] (2) It is configured within the first BWP, that is, each SSB in the first SSB set can be transmitted on the first BWP.
[0043] By ensuring that the SSBs in the first SSB set satisfy the aforementioned (1) and (2), that is, by configuring the SSBs within the BWP (such as the first BWP), the terminal and network-side devices can perform uplink and downlink data transmission within the BWP without frequently changing the transmission and reception frequencies and bandwidths. In other words, the terminal and network-side devices can complete data transmission and SSB-based synchronization, measurement, AGC (Automatic Gain Control), etc., within the same frequency and bandwidth, thereby reducing implementation complexity.
[0044] S220, the terminal transmits signals and / or channels on the second BWP based on the transmission method.
[0045] The transmission method may include the channel / signal types that the terminal can transmit on the second BWP, the transmission timing of the channel / signal transmitted on the second BWP (such as listening timing or sending timing), and which channels / signals can be used as transmission resources when transmitting on the second BWP.
[0046] In this embodiment, the terminal can operate in half-duplex mode under the Frequency Division Duplex (FDD) band, or the terminal can operate in asymmetric spectrum, that is, the terminal and / or network-side equipment cannot transmit and receive simultaneously. For example, if the network-side equipment transmits SSB or other downlink transmissions at any frequency position on the same symbol, the terminal will no longer perform uplink transmissions, thereby avoiding transmission overlap.
[0047] Furthermore, the terminal determines the transmission mode of the signal and / or channel on the second BWP based on the transmission configuration information and / or the first SSB set on the first BWP, and transmits the signal and / or channel on the second BWP based on the transmission mode. This enables the clear transmission behavior on the second BWP, reduces the transmission load on the first BWP, avoids transmission congestion and other problems, and improves wireless communication performance.
[0048] like Figure 3 The diagram shown is a flowchart of a transmission method 300 provided in an exemplary embodiment of this application. This method 300 can be executed by, but is not limited to, a terminal, specifically by hardware and / or software installed in the terminal. In this embodiment, the method 300 may include at least the following steps.
[0049] S310, the terminal determines the transmission mode of the signal and / or channel on the second BWP based on the transmission configuration information on the first BWP and / or the first SSB set.
[0050] It is understood that, in addition to referring to the relevant description in method embodiment 200, as a possible implementation, the transmission configuration on the first BWP may include at least one of the following (1)-(2).
[0051] (1) MO of the first PDCCH, the first PDCCH is used to schedule SIB.
[0052] (2) MO of the second PDCCH, the second PDCCH is the paging PDCCH.
[0053] As another implementation, the signals on the second BWP may include: a second SSB set; wherein the second SSB set may be configured within the second BWP.
[0054] Therefore, since the terminal needs to periodically receive SSBs for synchronization, measurement, etc., the network-side equipment can send the SSBs in the second SSB set within the bandwidth of the second downlink BWP or at an adjacent frequency position. This can avoid the problem of the terminal needing to frequently switch frequencies when receiving SSBs and other downlink receptions.
[0055] As one implementation, the period of the second SSB set can be different from the period of the first SSB set. For example, the period of the second SSB set can be no less than (e.g., greater than or equal to) the period of the first SSB set. For example, please refer to [reference needed]. Figure 4a The period of the second SSB set is twice that of the first SSB set, or in other words, the time period (half a frame) during which the second SSB set is transmitted is a subset of the time period (half a frame) during which the first SSB set is transmitted. Specifically, for the second SSB set, this embodiment uses a relatively longer transmission period than the first SSB set to transmit SSBs within the frequency range of the second BWP, satisfying the terminal's synchronization and measurement needs while reducing resource overhead and power consumption when transmitting SSBs in the second SSB set.
[0056] Furthermore, considering that SSBs in an SSB set are transmitted over a period of time, in addition to increasing the transmission period of the second SSB set as mentioned above, this embodiment can also reduce the number of SSBs transmitted within a period of time, i.e., the number of SSBs contained in the SSB set, which can also reduce the resource overhead and power consumption when transmitting SSBs in the second SSB set. Specifically, assuming the terminal needs to receive SSBs in the second SSB set, then the index values of each SSB in the second SSB set are the same as the index values of each SSB in the first SSB set; or, the index values of each SSB in the second SSB set are a subset of the index values of each SSB in the first SSB set. That is to say, when the network-side device transmits the second SSB set, the index values of the SSBs in the second SSB set can be the same as the index values of the first SSB, or the index values of the SSBs contained in the second SSB set are a subset of the index values of the SSBs contained in the first SSB set.
[0057] For example, suppose 1 = <M<=N<=L,n1,n2,…n N This represents the index value of the SSB in the first SSB set, m1, m2, ... m M This represents the index value of the SSB in the second SSB set. Therefore, (m1, m2, ... m... M )∈(n1,n2,…n N ), where L is the maximum number of SSBs that can be sent within the preset duration.
[0058] For example, such as Figure 4b As shown, the index values SSB#0, SSB#1, SSB#2, and SSB#3 of each SSB in the second SSB set are the same as the index values SSB#0, SSB#1, SSB#2, and SSB#3 of each SSB in the first SSB set; or, as shown... Figure 4c As shown, the index values SSB#0 and SSB#2 of each SSB in the second SSB set are subsets of the index values SSB#0, SSB#1, SSB#2, and SSB#3 of each SSB in the first SSB set.
[0059] In this scenario, if the index value of the second SSB in the second SSB set is the same as the index value of the first SSB in the first SSB set, then the first parameter of the first SSB is the same as or the first parameter of the second SSB is quasi-co-location (QCL). In this embodiment, since SSBs with the same index value are transmitted in the same time unit, and at the same time, due to implementation complexity, the network can only use one beam or a spatial transmission filter (STF) to transmit signals in some frequency bands, two SSBs at different frequency locations can also use the same beam for transmission. That is, when the index values of the SSBs in these two SSB sets are the same, the terminal can assume that these two SSBs are quasi-co-located to reduce the complexity of network implementation.
[0060] Optionally, the first parameter may include at least one of the following: Doppler shift, Doppler spread, average delay, delay spread, spatial Rx parameter, and average gain.
[0061] It should be noted that, for the aforementioned second SSB set and first SSB set, the SSBs in the second SSB set may be at least partially the same as or different from the SSBs in the first SSB set, and no restrictions are imposed here.
[0062] Furthermore, in addition to the aforementioned second SSB set, the network-side device can also configure the transmission of SIB-1 and paging messages (such as the first PDCCH and the second PDCCH) in the first downlink BWP. Correspondingly, the network-side device can also configure the transmission of SIB-1 and paging messages PDCCH in the configuration of the second BWP, thereby avoiding the problem of excessive overhead caused by transmission on the first BWP.
[0063] In this case, the channel on the second BWP described in this embodiment may include at least one of the following (1)-(3).
[0064] (1) The third PDCCH is used to schedule SIBs.
[0065] Optionally, the MO of the third PDCCH may include M, and each MO of the third PDCCH is associated with an SSB in the second SSB set with a corresponding index value, where M is an integer greater than 0.
[0066] (2) Fourth PDCCH, which is a paging PDCCH.
[0067] Optionally, the MO of the fourth PDCCH may include M, and each MO of the fourth PDCCH is associated with an SSB in the second SSB set with a corresponding index value, where M is an integer greater than 0.
[0068] (3) Physical uplink channel, which includes PUSCH and / or PUCCH.
[0069] Optionally, the transmission mode of the physical uplink channel on the second BWP may include: whether to transmit the physical uplink channel; and / or whether to use the physical uplink channel as a transmission resource.
[0070] It is understood that, corresponding to the terminal, the network-side device can also determine the transmission mode of the signal and / or channel on the second BWP based on the transmission configuration information on the first BWP and / or the first SSB set, such as the transmission mode of the SSB in the second SSB set, the transmission mode of the third PDCCH, the transmission mode of the fourth PDCCH, the reception mode of the physical uplink channel, etc. For this, please refer to the description of the terminal-side transmission method in this application. To avoid repetition, no restrictions are made here.
[0071] S320, the terminal transmits signals and / or channels on the second BWP based on the transmission method.
[0072] It is understood that, in addition to referring to the relevant description in method embodiment 200, the implementation of S320 is, as a possible implementation, taking into account that different signals and / or channels have different transmission methods on the second BWP, the transmission methods of the channels on the second BWP will be described below using the third PDCCH, the fourth PDCCH, the physical uplink channel, and the SSB in the second SSB set as examples.
[0073] Example 1
[0074] Assuming the channel on the second BWP is the third PDCCH, then the terminal transmits the third PDCCH on the second BWP based on the transmission method, including at least one of the following (11)-(13).
[0075] (11) Based on the second BWP, the third PDCCH is monitored on the first MO, and the time unit of the first MO and the MO of the first PDCCH are the same.
[0076] (12) Based on the second BWP, the third PDCCH is monitored on the second MO, the second MO is the same time unit as the MO of the first PDCCH associated with the third SSB, and the third SSB is an SSB in the first SSB set that has the same index value as the SSB in the second SSB set.
[0077] (13) In the case where an SSB with a third index value in the first SSB set has been transmitted, but an SSB with the third index value in the second SSB set has not been transmitted, based on the second BWP, the third PDCCH is not monitored in the time unit corresponding to the third MO, where the third MO is in the same time unit as the first PDCCH associated with the SSB with the third index value in the first SSB set.
[0078] Optionally, the time unit mentioned in (11)-(13) above and in subsequent embodiments can be a time slot, symbol, frame, etc., and there are no restrictions here.
[0079] Based on the description of Example 1 above, the implementation process of Example 1 will be further explained below with reference to the accompanying drawings.
[0080] For the first PDCCH or the second PDCCH (i.e., the PDCCH for scheduling SIB1), the MO of the PDCCH in the first downlink BWP (initial downlink BWP), that is, the MO of the first PDCCH, is indicated by the PBCH in the SSB in the first SSB set. Therefore, the MO of the first PDCCH is associated with the corresponding SSB in the first SSB set that has the corresponding index value. The association relationship is as follows: Figure 4d As shown, where:
[0081] If the index values of the SSBs in the second SSB set are exactly the same as those in the first SSB set, then the MO of the third PDCCH transmitted on the second downlink BWP is the same as the MO of the first PDCCH.
[0082] If the SSBs in the second SSB set are a subset of the SSBs in the first SSB set (i.e., some SSBs with certain index values sent in the first SSB set are not sent in the second SSB set), then the MO of the third PDCCH on the second downlink BWP is associated with the SSB index values in the second SSB set. In this case, the position of the MO of the third PDCCH is the same as the sign of the MO of the first PDCCH on the first downlink BWP that is associated with the same index value SSB.
[0083] For example, if the SSBs sent in the first SSB set are SSB#0, SSB#1, SSB#2, and SSB#3, and the SSBs sent in the second SSB set are also SSB#0, SSB#2, and SSB#3, then the MO of the third PDCCH associated with these three SSBs on the second downlink BWP is the same symbol as the MO of the first PDCCH associated with SSB#0, SSB#2, and SSB#3 in the first downlink BWP and the first SSB set. On the symbol of the PDCCH MO associated with SSB#1 in the second downlink, the terminal does not listen for the third PDCCH.
[0084] In this embodiment, corresponding to the terminal listening to the third PDCCH, the network-side device transmits the third PDCCH on the second BWP based on the second BWP. This may include: when the MO of the third PDCCH corresponds one-to-one with the SSBs in the second SSB set, the third PDCCH is transmitted on the second BWP according to the transmission time order of the SSBs in the second SSB set, and the transmission parameters of the third PDCCH and its corresponding SSB are quasi-co-addressable.
[0085] Example 2
[0086] Assuming the channel on the second BWP is the third PDCCH, then the terminal transmits the fourth PDCCH on the second BWP based on the transmission method, including at least one of the following (21)-(23).
[0087] (21) Based on the second BWP, the fourth PDCCH is monitored on the fourth MO, wherein the fourth MO is in the same time unit as the MO of the second PDCCH.
[0088] (22) Based on the second BWP, the fourth PDCCH is monitored on the fifth MO, wherein the fifth MO is in the same time unit as the MO of the second PDCCH associated with the fourth SSB, and the fourth SSB is an SSB in the first SSB set that has the same index value as the SSB in the second SSB set.
[0089] (23) In the case where an SSB with the fourth index value in the first SSB set has been transmitted, but an SSB with the fourth index value in the second SSB set has not been transmitted, based on the second BWP, the fourth PDCCH is not monitored in the time unit corresponding to the sixth MO, where the sixth MO is in the same time unit as the MO of the second PDCCH associated with the SSB with the fourth index value in the first SSB set.
[0090] For the channel transmission methods described in Examples 1 and 2 above, when the MO of the fifth PDCCH is associated with the fifth SSB having a fifth index value, the second parameter of the fifth PDCCH is the same as or quasi-co-located with the second parameter of the fifth SSB.
[0091] Wherein, if the fifth PDCCH is the first PDCCH or the second PDCCH, the fifth SSB belongs to the first SSB set; if the fifth PDCCH is the third PDCCH or the fourth PDCCH, the fifth SSB belongs to the second SSB set.
[0092] The second parameter includes at least one of the following: Doppler frequency shift, Doppler spread, average delay, delay spread, spatial reception parameters, and average gain.
[0093] Based on the description of Example 2 above, the implementation process of Example 2 will be further explained below with reference to the accompanying drawings.
[0094] For paging messages, the terminal listens for the second or fourth PDCCH (i.e., paging PDCCH) during the paging time (PO). A PO can contain the MOs of the paging PDCCH corresponding to multiple SSBs sent by the network-side device (the MOs of the second or fourth PDCCH and the MOs of the SSBs sent by the network correspond to each other in the order of index values). The paging PDCCH is listened for during the initial downlink BWP (first downlink BWP).
[0095] If the SSB index transmitted in the second SSB set is exactly the same as that in the first SSB set, then the MO of the fourth PDCCH on the second downlink BWP is the same as the MO of the second PDCCH.
[0096] If the SSBs in the second SSB set are a subset of the SSBs in the first SSB set (i.e., some SSBs with certain index values sent in the first SSB set are not sent in the second SSB set), and the MO of the fourth PDCCH on the second downlink BWP is associated with the SSB index in the second SSB set, then the position of the MO of the fourth PDCCH is the same as the sign of the MO of the second PDCCH on the first downlink BWP that is associated with the same index value SSB.
[0097] One example is as follows: Figure 4e As shown, on the first downlink BWP, the first SSB set contains SSB#0, SSB#1, SSB#2, and SSB#3. In a PO, there are MOs associated with four SSBs, namely the paging PDCCHs (such as P-MO#0, P-MO#1, P-MO#2, and P-MO#3).
[0098] If the second SSB set is a subset of the SSBs sent by the first SSB set, for example, if the second SSB set sends SSB#0 and SSB#2, then the MO symbol of the fourth PDCCH associated with these two SSBs on the second downlink BWP is the same as the MO symbol of the second PDCCH associated with the same index SSB on the first downlink BWP. Simultaneously, on the second downlink BWP, the terminal does not listen for the fourth PDCCH on the MO symbols of the PDCCHs corresponding to SSB#1 and SSB#3.
[0099] Especially for certain high-frequency bands, network-side devices cannot transmit SSBs at different frequencies at the same time, or PDCCHs may use different beams for transmission. In such cases, SSBs with the same index transmitted at the same time will have the same beam. When paging PDCCHs or scheduling SIB-1 PDCCHs associated with SSBs of the same index, the transmitting beam is also the same. Restricting the MO of PDCCHs associated with the same SSB on different BWPs to be the same allows the network to transmit PDCCHs associated with the same SSB index number at different frequencies using the same beam, reducing the complexity of network implementation.
[0100] In this embodiment, corresponding to the terminal listening to the fourth PDCCH, the network-side device transmits the fourth PDCCH on the second BWP, including: when the MO of the fourth PDCCH corresponds one-to-one with the SSB in the second SSB set, the fourth PDCCH is transmitted on the second BWP according to the transmission time order of the SSB in the second SSB set, and the transmission parameters of the fourth PDCCH and its corresponding SSB are quasi-co-located.
[0101] For the aforementioned Examples 1 and 2, if the network-side device is configured with a second downlink BWP that includes the listening of the third and fourth PDCCHs, the terminal can directly determine which SSBs associated with the third and fourth PDCCHs, and the corresponding PDCCH MOs, can be listened to by the second downlink BWP based on the SSBs contained in the second SSB set.
[0102] Example 3
[0103] Assuming the channel on the second BWP is the physical uplink channel, then the terminal transmits the physical uplink channel on the second BWP based on the transmission method, including: not transmitting the physical uplink channel in the first time unit. That is, if the network device configures the terminal to use the second uplink BWP and indicates that transmission is performed on the second uplink BWP, then if the first time unit is used for any of the following (31)-(36), the terminal will not transmit the physical uplink channel (such as PUSCH, PUCCH) in the first time unit. This avoids conflicts between uplink transmission resources and downlink transmission resources (such as the transmission resources for transmitting SSBs in the first SSB set, SSBs in the second SSB set, the first PDCCH, and the first PDCCH as described in (31)-(36), thus improving wireless communication performance.
[0104] In this embodiment, the first time unit includes at least one of the following (31)-(36).
[0105] (31) Transmit the time elements of the SSBs in the first SSB set.
[0106] (32) Transmit the time unit of the SSB in the second SSB set.
[0107] Among them, the index value of the SSB in the second SSB set mentioned above (32) can be the same as the index value of the SSB in the first SSB set in (31), or it can be a subset of the index value of the SSB in the first SSB set in (31).
[0108] (33) The time unit in which the MO of the first PDCCH is located.
[0109] (34) The time unit in which the MO of the second PDCCH is located.
[0110] (35) The time unit in which the MO of the third PDCCH is located.
[0111] The MO of the third PDCCH can be the same as the MO of the first PDCCH, or it can be a subset of the MO of the first PDCCH.
[0112] (36) The time unit in which the MO of the fourth PDCCH is located.
[0113] The MO of the fourth PDCCH can be the same as the MO of the second PDCCH, or it can be a subset of the MO of the second PDCCH.
[0114] It is understandable that in this example 3, the time units occupied by more than one set of SSBs (such as the first SSB set and the second SSB set) or more than one SIB-1 on BWP or the MO corresponding to the paging PDCCH are comprehensively considered to determine the transmission resources of PUCCH or PUSCH.
[0115] In one implementation, the transmission of PUCCH or PUSCH can be repeated. For resources that determine repeated transmission of PUCCH or PUSCH, there are two modes.
[0116] The first mode: The terminal transmits on N consecutive slots. If there is a symbol in a slot that is used for the downlink transmission mentioned above, the terminal will not repeat the transmission of PUCCH or PUSCH on that slot (transmit as many as possible out of the N slots).
[0117] The second mode: The terminal determines N available slots for repeated transmission. If a symbol allocated on a certain slot is used for the aforementioned downlink transmission, this slot is not an available slot. The terminal continues to determine whether subsequent slots are available slots until N available slots are determined for repeated transmission of PUCCH or PUSCH.
[0118] like Figure 4f As shown, for half-duplex terminals in the FDD band, or in asymmetric spectrum, meaning the terminal and / or network-side equipment cannot transmit and receive simultaneously (e.g., the network-side equipment transmits an SSB or other downlink transmission at any frequency position on the same symbol), the terminal will no longer perform uplink transmission (e.g., ...). Figure 4f The "shaded PUSCH" shown in the image.
[0119] Alternatively, the terminal does not expect network-scheduled or configured PUSCH and PUCCH transmissions, or transmissions of SSBs at arbitrary frequency locations (SSBs in any SSB set), and / or, symbolic overlap with the transmissions of the first to fourth PDCCHs. In other words, network-side device-scheduled or configured PUSCH and PUCCH transmissions should avoid symbolic overlap with the aforementioned downlink transmissions (such as the first SSB set, the second SSB set, etc.). Figure 4f The shaded area indicates that the PUSCH is not sent on this symbol.
[0120] In this embodiment, corresponding to the terminal not transmitting the physical uplink channel in the first time unit, the network-side device may not receive the physical uplink channel in the second time unit.
[0121] The second time unit includes at least one of the following (41)-(46).
[0122] (41) Transmit the time unit of the SSB in the first SSB set.
[0123] (42) The time unit for transmitting the SSB of the second SSB set.
[0124] (43) The time unit in which the MO of the first PDCCH is located.
[0125] (44) The time unit in which the MO of the second PDCCH is located.
[0126] (45) The time unit in which the MO of the third PDCCH is located.
[0127] (46) The time unit in which the MO of the fourth PDCCH is located.
[0128] It is understood that the second time unit may be the same as or different from the first time unit, and there is no restriction on this. In addition, the implementation process of (41)-(46) can be referred to the description of (31)-(36) above, and will not be repeated here.
[0129] Example 4
[0130] Assuming the channel on the second BWP is the second SSB set, then the terminal transmits the SSBs in the second SSB set on the second BWP based on the transmission method, including: the terminal can receive the first SSB using the same receiving parameters (such as beam, power, codebook, etc.) as the first SSB.
[0131] Correspondingly, the network-side device can also transmit the first SSB using the same transmission parameters (such as beam, power, codebook, etc.) as the first SSB. For example, the network-side device transmits the first SSB set at the first frequency position, which contains N CD-SSBs. At the same time, the network will configure a first downlink BWP, which is an initial downlink BWP used to transmit the first PDCCH for scheduling SIB-1, the PDSCH for paging messages, and the PDCCH for scheduling these PDSCHs.
[0132] For example, please combine again Figure 4b and Figure 4c As shown, the transmission periods of the second SSB set and the first SSB set are also different. The transmission period of the second SSB set is greater than or equal to the transmission period of the first SSB set. At this time, the transmission time period (half frame) of the second SSB set is a subset of the transmission time period (half frame) of the first SSB set.
[0133] Alternatively, the process of the network-side device sending the second SSB set may include the following: the index value of the SSB sent in the second SSB set is the same as the index value of the first SSB, or the SSBs contained in the second SSB set are a subset of the SSBs contained in the first SSB set.
[0134] In summary, the duration of transmission of the second SSB set, or the SSBs transmitted within that duration, is a subset of the first SSB set. In other words, SSBs in the second SSB set can only be transmitted on symbols where SSBs were transmitted in the first SSB set.

This method 500 can be executed by, but is not limited to, a terminal, specifically by hardware and / or software installed in the terminal.

[0143] In another possible implementation, when the index value of the second SSB in the second SSB set is the same as the index value of the first SSB in the first SSB set, the transmission parameters of the first SSB are the same as the transmission parameters of the second SSB.
[0144] In another possible implementation, the network-side device transmits a third PDCCH on the second BWP based on the transmission method, including: when the MO of the third PDCCH corresponds one-to-one with the SSBs in the second SSB set, transmitting the third PDCCH on the second BWP according to the transmission time order of the SSBs in the second SSB set, and the transmission parameters of the third PDCCH and its corresponding SSB are quasi-co-located; and / or, the network-side device transmits a fourth PDCCH on the second BWP based on the transmission method, including: when the MO of the fourth PDCCH corresponds one-to-one with the SSBs in the second SSB set, transmitting the fourth PDCCH on the second BWP according to the transmission time order of the SSBs in the second SSB set, and the transmission parameters of the fourth PDCCH and its corresponding SSB are quasi-co-located.
[0145] In another possible implementation, the network-side device transmits the physical uplink channel on the second BWP based on the transmission method, including: not receiving the physical uplink channel in the second time unit; wherein the second time unit includes at least one of the following: a time unit for transmitting SSBs in the first SSB set; a time unit for transmitting SSBs in the second SSB set; a time unit where the MO of the first PDCCH is located; a time unit where the MO of the second PDCCH is located; a time unit where the MO of the third PDCCH is located; and a time unit where the MO of the fourth PDCCH is located.
