[0059] For ease of understanding, some of the contents involved in the embodiments of this application are described below:

[0060] 1. Reasons and benefits of introducing one flexible cell

[0061] Sub-3GHz spectrum has advantages such as low penetration loss and plays an important role in cellular network deployment due to its good coverage. On the other hand, compared with the C-band, the Sub-3GHz spectrum is allocated to International Mobile Telecommunications (IMT) in a fragmented manner, and the bandwidth of each spectrum block is relatively narrow due to competition among mobile operators. On the other hand, almost all operators in the world own multiple Sub-3GHz bands (such as 700MHz, 800MHz, 900MHz, 1.4GHz, 1.8GHz, 2.1GHz, 2.3GHz or 2.6GHz bands). If these discontinuous spectrums can be effectively aggregated to form a "single" carrier with considerable bandwidth, all operators can benefit.

[0062] Compared with Long Term Evolution (LTE), New Radio (NR) provides significant capacity and experience advantages by using broadband communications and massive Multiple In Multiple Out (MIMO). Specifically, current applications that require high-throughput communications require wide bandwidth. Therefore, broadband operation on these discontinuous sub-3GHz spectrums will be key to meeting the growing requirements of industrial-grade Internet of Things (ToB) and consumer-grade Internet of Things (ToC) in the future. Therefore, a potential solution is a flexible cell, which can contain fragmented spectrum resources, with the aim of efficiently and flexibly utilizing these fragmented continuous or discontinuous spectrums.

[0063] 2. 5G non-RedCap initial bandwidth part (BWP) and resource set 0 (CORESET#0)

[0064] The initial downlink and uplink BWPs, namely the initial downlink BWP (Initial DL BWP) and the initial uplink BWP (Initial UL BWP), are configured in the System Information Block (SIB) 1. If the initial BWP is not configured, the default size of the initial BWP is the size of CORESET#0. The initial BWP is mainly used for the initial access process, such as receiving SIB1, receiving the random access response (RAR) and Msg4 during the random access process, and sending the preamble and Msg3.

[0065] Terminal-side process of cell search / initial access:

[0066] 1. Receive the Synchronization Signal Block (SSB), decode the Master Information Block (MIB) carried in the Physical Broadcast Channel (PBCH) in the SSB, and obtain the CORESET#0 information;

[0067] 2. Monitor the downlink control information (DCI) of SIB1 in CORESET#0;

[0068] 3. Decode SIB1 and obtain the initial DL / UL BWP and the control resource set (CORESET) of RAR / msg4 DCI.

[0069] CORESET: defines information such as the frequency domain resources occupied by the Physical Downlink Control Channel (PDCCH) carrying DCI in the frequency domain and the number of Orthogonal Frequency Division Multiplexing (OFDM) symbols occupied in the time domain.

[0070] The NR PDCCH channel has multiple search spaces, including common search spaces and UE-specific search spaces, as shown in the following table:

[0071] 3. 5G RedCap separate initial DL / UL BWP

[0072] For redcap (reduced capability) user equipment (UE), since the supported bandwidth is less than or equal to the bandwidth capability of ordinary UE, the initial BWP bandwidth configured by the network for ordinary UE may exceed the capability of redcap UE. In this case, the network can configure an additional / independent initial BWP for the redcap UE so that the bandwidth of the BWP is within the capability range of the redcap UE.

[0073] Furthermore, since redcap UEs have fewer receive antennas than standard UEs, their reception performance is inferior to standard UEs, potentially leading to the network using greater overhead and resources to transmit to redcap UEs. Therefore, even if the bandwidth of the BWP configured by the network is within the capabilities of the redcap UE, if the network uses the same BWP for transmission to both standard and redcap UEs, the load on the BWP will be excessive, potentially causing congestion for transmissions to standard terminals. Therefore, the new redcap work item concluded the following:

[0074] 1. The network can configure a separate initial DL BWP for the redcap UE. If the separate initial BWP does not include the Cell-Defining SSB (CD-SSB) and the entire CORESET#0,

[0075] If the separate initial BWP is configured with a search space for random access related operations, namely Type 1 CSS, but no paging related search space is configured, the separate initial BWP may not include SSB / CORESET#0 / SIB.

[0076] Redcap UEs in RRC_IDLE and RRC_INACTIVE states need to monitor paging messages in the initial BWP of non-Redcap associated with CD-SSB. That is, redcap UEs in RRC_IDLE and RRC_INACTIVE states are not further considered to monitor paging messages in the initial BWP associated with CD-SSB.

[0077] 2. For the active DL BWP configured by the redcap UE of RRC_CONNECTED, if it does not include CD-SSB and the entire CORESET#0, then

[0078] A basic capability RedCap UE expects the active DL BWP to contain the NCD-SSB for the serving cell but not CORESET#0 / SIB.

[0079] A RedCap UE with higher capabilities may operate on an active DL BWP that does not contain any SSB.

[0080] Note: The NCD-SSB cycle does not need to be configured the same as the CD-SSB cycle.

[0081] Note: The period of NCD-SSB should not be less than that of CD-SSB.

[0082] 4. Spectrum Sharing among Different Wireless Communication Systems

[0083] Operators often operate multiple network standards simultaneously. After 5G is deployed, scenarios will exist where 2G, 3G, 4G, and 5G will operate simultaneously. With the increasing demand for mobile broadband network traffic, operators are refarming their 2G / 3G networks to 4G, and then refarming from 4G to 5G. In traditional operators' multi-standard networks, each standard requires a fixed amount of spectrum resources. Since each standard has exclusive spectrum, if spectrum between different standards cannot be shared during peak hours, it will lead to significant waste of spectrum resources. Currently, a project on 4G and 5G spectrum sharing has been launched. This technology can dynamically allocate spectrum resources to 4G or 5G on demand within the same frequency band.

[0084] The method in the embodiment of the present application is applicable to 5G, 6G and subsequent evolution communication systems.

[0085] The following, in conjunction with the accompanying drawings, describes in detail the transmission configuration method, apparatus, terminal, network device, and storage medium provided in the embodiments of the present application through some embodiments and their application scenarios.

[0086] As shown in FIG2 , the transmission configuration method according to an embodiment of the present application includes:

[0087] Step 201: A network device determines configuration information of a serving cell of a terminal, where the serving cell includes multiple frequency domain units configured for the terminal, and at least two frequency domain units are non-contiguous in the frequency domain.

[0088] In step 202, the network device sends the configuration information of the service cell to the terminal; wherein the configuration information of the service cell includes at least one of the following: first information, the first information is the condition information satisfied by the multiple frequency domain units; second information, the second information is the characteristic information of the frequency domain resources of the service cell.

[0089] In this way, according to the above steps, the network equipment can, based on scattered frequency domain resources, determine the configuration information of a service cell of the terminal and inform the terminal of the configuration information of the service cell, so as to flexibly define a service cell for the terminal. The service cell includes multiple frequency domain units configured for the terminal, and at least two frequency domain units are non-continuous in the frequency domain, so that the network can flexibly and efficiently utilize scattered frequency domain resources from the perspective of L1 / L2 / L3 signaling, process and cell management, thereby improving system capacity and coverage. For the terminal side, the aggregated spectrum can increase the user-perceived data rate, save energy, reduce latency, and improve perceived coverage.

[0090] It should be noted that the frequency domain unit can be configured for the terminal in units of resource blocks (RB), RB sets (RBS), RB groups (RB Groups, RBG), and BWPs.

[0091] Optionally, in this embodiment, the first information includes at least one of the following:

[0092] The transmission parameters of the first signal on the multiple frequency domain units are quasi-co-located;

[0093] Transmission parameters of the second signal associated with the control channel or the data channel on the multiple frequency domain units are quasi-co-located;

[0094] The transmission parameters of the first signal and the transmission parameters of the second signal are quasi-co-located, wherein the first signal is a signal on the multiple frequency domain units, and the second signal is a signal associated with a control channel or a data channel on the multiple frequency domain units;

[0098] Among them, the first information includes that the transmission parameters of the first signal on the multiple frequency domain units are quasi-co-located, which means that corresponding to the multiple frequency domain units included in the service cell, the transmission parameters of the first signal on different frequency domain units can be quasi-co-located, such as the multiple frequency domain units 1 and 2 included in the service cell, the transmission parameters of the first signal on frequency domain unit 1 and the transmission parameters of the first signal on frequency domain unit 2 are quasi-co-located.

This means that in addition to the transmission parameters between the first signals and the second signals being quasi-co-located, the transmission parameters of the first signal and the transmission parameters of the second signal can also be quasi-co-located. For example, in a serving cell comprising multiple frequency domain units 1 and 2, the transmission parameters of the first signal on frequency domain unit 1 and the transmission parameters of the second signal associated with the control channel or the data channel on frequency domain unit 1 are quasi-co-located.

Optionally, T1_difference can be determined based on a set value, such as a set value of 260ns, then T1_difference = ±260ns.

[0103] The first information includes that the difference in uplink timing advance between different frequency domain units satisfies the second time range, indicating that for the multiple frequency domain units included in the serving cell, the difference in uplink timing advance between any two frequency domain units satisfies the second time range T2_difference.

The first time range and the second time range can be the same or different.

[0104] The first information includes that the difference in downlink power of different frequency domain units is less than or equal to a first threshold, which means that for the multiple frequency domain units included in the serving cell, the difference in downlink power of any two frequency domain units is less than or equal to the first threshold P_difference. Optionally, P_difference is pre-set, such as P_difference = 6dB.

[0105] Optionally, in this embodiment, the network device may select, based on at least one item of the first information, a plurality of frequency domain units that meet the conditions from the candidate frequency domain units as the plurality of frequency domain units included in the serving cell.

[0118] Among them, the second information includes whether the multiple frequency domain units are continuous or discontinuous in the frequency domain, which may indicate that for the multiple frequency domain units included in the service cell, different frequency domain units are all discontinuous in the frequency domain, or partially continuous and partially discontinuous, such as the multiple frequency domain units 1, 2 and 3 included in the service cell, the three frequency domain units are all discontinuous in the frequency domain, or frequency domain units 1 and 2 are continuous in the frequency domain, but are discontinuous with frequency domain unit 3.

Of course, different frequency domain units may have different states.

[0126] Optionally, in this embodiment, an interval between adjacent non-contiguous frequency domain units in the multiple frequency domain units is less than or equal to a second threshold.

[0127] Thus, for the multiple frequency domain units included in the serving cell, the interval between adjacent discontinuous frequency domain units (i.e., non-continuous frequency domain units) in the multiple frequency domain units is less than or equal to the second threshold. This interval may also be referred to as a frequency offset or gap. The second threshold is a preset interval threshold F_threshold.

[0128] Optionally, in this embodiment, the method further includes:

[0129] The network device determines, on the serving cell, configuration information of a first primary anchor point bandwidth part BWP of the terminal;

[0130] The network device sends configuration information of the first primary anchor point BWP to the terminal;

[0131] The configuration information of the first main anchor point BWP includes at least one of the following:

[0132] Third information, the third information being characteristic information of the first main anchor point BWP;

[0134] That is, for the serving cell configured for the terminal, the network device will further determine the configuration information of the first anchor point BWP (FA BWP) of the terminal and inform the terminal of the configuration information so that the terminal can perform subsequent transmission.

[0135] Optionally, the third information serves as characteristic information of the first main anchor point BWP, and the network device may determine the first main anchor point BWP based on the third information.

[0136] Optionally, the third information includes at least one of the following:

[0137] The first primary anchor point BWP is used to transmit non-access stratum (NAS) mobility information when a radio resource control (RRC) connection is established, reestablished, or switched, and is used for secure transmission when an RRC connection is reestablished or switched;

[0139] The first main anchor point BWP is configured to be in an activated state;

[0140] The first main anchor point BWP is not allowed to be configured as a dormant state or a deactivated state.

[0141] Among them, the first main anchor point BWP is used to transmit NAS mobility information when the RRC connection is established, rebuilt or switched, indicating that the first main anchor point BWP will provide NAS mobility information when the RRC connection is established, rebuilt or switched; it is used for secure transmission when the RRC connection is rebuilt or switched, indicating that the first main anchor point BWP will provide security input when the RRC connection is rebuilt or switched.

[0142] Optionally, the fourth information is information about a first target supported for transmission by the first main anchor point BWP. It can also be understood that the fourth information indicates the first target supported for transmission by the first main anchor point BWP.

[0143] Optionally, the first goal includes at least one of the following:

[0144] CD-SSB, Tracking reference signal (TRS), system information, broadcast information, transmission object during initial access, transmission object during random access, transmission object during small data transmission, paging information, Paging Early Indication (PEI), terminal group common information, user data.

[0145] Optionally, in this embodiment, the method further includes:

[0146] The network device determines, on the serving cell, configuration information of a second primary anchor point BWP of the terminal;

[0147] The network device sends configuration information of the second primary anchor point BWP to the terminal;

[0148] The configuration information of the second main anchor point BWP includes fifth information, and the fifth information is information about a second target supported for transmission by the second main anchor point BWP.

[0149] That is, for the serving cell configured for the terminal, the network device will further determine the configuration information of the second anchor point BWP (SA BWP) of the terminal and inform the terminal of the configuration information for subsequent transmission of the terminal. Of course, the network device configures one or more SA BWPs for the terminal.

[0150] The fifth information is information about the second target supported for transmission by the second main anchor point BWP. It can also be understood that the fifth information indicates the second target supported for transmission by the second main anchor point BWP and indicates the purpose of the second main anchor point BWP.

[0151] Optionally, the configuration information of the second primary anchor point BWP includes at least one of the following: a frequency domain location of the second primary anchor point BWP, a frequency domain resource size, a first feature / function associated with the second primary anchor point BWP, and a transmission target associated with the first feature / function. The first feature / function includes at least one of the following: a terminal type, a terminal capability, and a service type.

[0152] Optionally, the second goal includes at least one of the following:

[0153] Non-cell defined synchronization signal block NCD-SSB, TRS, system information, broadcast information, transmission object during initial access, transmission object during random access, transmission object during small data transmission, paging information, PEI, terminal group common information, user data.

[0154] The first and second objectives are described in detail as follows:

[0155] The system information may be system information of the serving cell scheduled by a PDCCH, and the PDCCH is received through a Type0 CSS or a Type0A CSS.

[0156] The broadcast information may be broadcast information scheduled by a PDCCH, and the PDCCH is received through a Type0 BCSS.

[0157] The paging information may be scheduled by a PDCCH, and the PDCCH is received through a Type 2 CSS.

[0158] Among them, PEI can be received through Type2A CSS.

[0159] The terminal group common information may be DCI scheduled, and the DCI is received via Type 3 CSS.

[0160] The user data may be scheduled by a PDCCH, and the PDCCH is received by a UE SS.

[0161] Therefore, in this embodiment, the first target or the second target may further include at least one of the PDCCH and DCI that schedule the above information.

[0162] Optionally, the transmission object in the initial access process, the transmission object in the random access process, and the transmission object in the small data transmission process may include a first uplink transmission object and a first downlink transmission object.

[0163] The first uplink transmission object is also called the first uplink transmission (First UL Tx), which includes at least one of the following: PRACH, message A (MSGA), small data transmission based on authorization (Small Data Transmission-Configured Grant, SDT-CG), and PUCCH.

[0164] Here, PRACH can include at least one of the following: PRACH in initial access, PRACH in four-step random access, small data transmission based on PRACH (SDT-PRACH), and PDCCH order-triggered PRACH. MSGA includes MSGA PRACH and MSGA PUSCH. PUCCH is a PUCCH carrying HARQ-ACK information transmitted on the cell-common PUCCH.

[0165] The first downlink transmission object is also called the first downlink transmission (First UL Tx), which includes at least one of the following: SSB, RAR, MSG2, and MSGB.

[0166] In this embodiment, after receiving the configuration information of the first main anchor point BWP and the configuration information of the second main anchor point BWP, the terminal can select the third main anchor point BWP and perform at least one of the following operations: initial access; random access; small data transmission; monitoring paging messages; receiving PEI; receiving sent broadcast information.

[0167] Optionally, the terminal selects a third primary anchor point BWP based on at least one of the following:

[0168] Instruction information of the network device;

[0169] The first BWP information defined;

[0170] an identification (ID) of the terminal;

[0171] The size of the BWP;

[0172] The third primary anchor point BWP is configured with a transmission target associated with at least one of the following: terminal type, terminal capability, and service type.

[0173] Here, the information used by the terminal to select the third primary anchor point BWP may be referred to as a first selection criterion.

[0174] The indication information of the network device is used to instruct the terminal which one to select between the FA BWP and the SA BWP as the third main anchor point BWP. For example, if the indication information indicates the FA BWP, the terminal selects the FA BWP as the third main anchor point BWP. For another example, if the indication information indicates that the third main anchor point BWP is the SA BWP that transmits SSB or TRS, the terminal selects the SA BWP that transmits SSB or TRS as the third main anchor point BWP.

[0175] Among them, the defined first BWP information is the information of the BWP that the terminal prefers to select between FA BWP and SA BWP as specified by the protocol. For example, if the first BWP information includes the BWP identifier (ID), the terminal selects the corresponding BWP as the third main anchor point BWP according to the BWPID; if the first BWP information includes the transmission SSB or TRS of the BWP, the terminal selects the SA BWP or FA BWP that transmits SSB or TRS as the third main anchor point BWP.

[0176] The terminal's identifier can be used to determine the identifier of the third primary anchor point BWP, such as by determining the ID of the third primary anchor point BWP through (UE_ID mod N) or (UE_ID mod N) + 1, where N = (total number of FA BWPs + total number of SA BWPs), or N = total number of SA BWPs.

[0177] Among them, the size of BWP can be understood as the size of FA BWP and the size of SA BWP. For example, the terminal can select the BWP with the largest or smallest bandwidth as the third main anchor point BWP based on the size of FA BWP and the size of SA BWP. For example, the terminal can compare its own capabilities, such as the size of the bandwidth it supports, with the size of FA BWP and the size of SA BWP, and select a BWP that is smaller than or equal to the size of the BWP supported by the terminal as the third main anchor point BWP.

[0178] The supported transmission target can be understood as the desired transmission target of the third primary anchor point BWP. For example, if the supported transmission target is SSB or TRS, the terminal can select a BWP that supports transmission of SSB or TRS as the third primary anchor point BWP. Of course, the supported transmission target can be limited to SA BWP, in which case the terminal can select an SA BWP that supports transmission of SSB or TRS as the third primary anchor point BWP.

[0179] Among them, the third main anchor point BWP is configured with a transmission target associated with at least one of the following: terminal type, terminal capability, and service type. It can be understood that the third main anchor point BWP that the terminal expects to select is a BWP configured with a transmission target associated with at least one of the terminal type, terminal capability, and service type.

[0180] In this embodiment, the transmission target includes at least one of the following: broadcast information, a transmission target during initial access, a transmission target during random access, a transmission target during small data transmission, paging information, and PEI. Thus, the terminal may select a third primary anchor point (BWP) configured to receive broadcast information associated with different terminal types.

[0181] In this embodiment, the terminal type includes at least one of the following: UE supporting enhanced Mobile BroadBand (eMBB), UE supporting Ultra-Reliable Low-Latency Communications (URLLC), RedCapUE, UE supporting Multimedia Telephone Communication (MTC), UE supporting Internet of Things (IoT), and UE supporting eXtended Reality (XR). The terminal capability includes at least one of the following: maximum supported bandwidth (including radio frequency bandwidth, baseband bandwidth, system bandwidth, channel bandwidth, etc.), supported frequency band, and downlink processing capability. The service type can also be understood as a use case type, and the service type includes at least one of the following: eMBB, URLLC, XR, IoT, and non-terrestrial network (NTN).

[0182] Of course, the terminal may also select the third main anchor point BWP based on its own implementation, such as random selection.

[0183] In this embodiment, the terminal selects the third primary anchor point BWP based on the first selection criterion, which is applicable to the case where the network device configures multiple SA BWPs for the terminal, and the multiple SA BWPs support at least one of the following transmissions:

[0184] Broadcast information, transmission objects during initial access, transmission objects during random access, transmission objects during small data transmission, paging information, PEI.

[0185] In addition, considering that the terminal may select multiple third main anchor points BWP, in this embodiment, optionally, when the terminal selects multiple third main anchor points BWP, the terminal selects a fourth main anchor point BWP from the multiple third main anchor points BWP based on at least one of the following:

[0186] The second BWP information defined;

[0187] BWP's logo;

[0188] an identifier of the terminal;

[0189] The size of the BWP;

[0190] Supported transfer targets.

[0191] Here, the plurality of third primary anchor points BWPs may be FA BWPs and at least one SA BWP, or only a plurality of SA BWPs. The information used by the terminal to select the fourth primary anchor point BWP may be referred to as a second selection criterion.

[0192] Among them, the defined second BWP information is the information of the BWP that the terminal preferentially selects among multiple third main anchor points BWP as specified by the protocol. For example, if the first BWP information includes the BWP ID, the terminal selects the corresponding BWP as the fourth main anchor point BWP according to the BWPID; if the first BWP information includes the transmission SSB or TRS of the BWP, the terminal selects the SA BWP or FA BWP that transmits SSB or TRS as the fourth main anchor point BWP.

[0193] Among them, the ID of BWP can be understood as the ID of SA BWP, such as the terminal selects the SA BWP with the largest or smallest ID among multiple SA BWPs as the fourth main anchor point BWP; it can also be understood as the ID of all third main anchor points BWP, such as the terminal selects the third main anchor point BWP corresponding to the largest or smallest ID as the fourth main anchor point BWP.

[0194] The terminal identifier can be used to determine the identifier of the fourth primary anchor point BWP, such as by determining the ID of the fourth primary anchor point BWP using (UE_ID mod N) or (UE_ID mod N) + 1. Where N = (total number of FA BWPs + total number of SA BWPs), or N = total number of SA BWPs, or N = M, where M is the total number of FA BWPs that meet the first selection criterion and / or the total number of SA BWPs that meet the first selection criterion.

[0195] The size of the BWP can be understood as the size of all third main anchor point BWPs. For example, the terminal can select the BWP with the largest or smallest bandwidth as the fourth main anchor point BWP based on the sizes of all third main anchor point BWPs. It can also be understood as the size of the SA BWP. For example, the terminal selects the SA BWP with the largest or smallest bandwidth as the fourth main anchor point BWP.

[0196] The supported transmission target can be understood as the desired transmission target of the fourth primary anchor point BWP. For example, if the supported transmission target is SSB or TRS, the terminal can select the third primary anchor point BWP that supports transmission of SSB or TRS as the fourth primary anchor point BWP. Of course, the supported transmission target can be limited to SA BWP, in which case the terminal can select SA BWP that supports transmission of SSB or TRS as the fourth primary anchor point BWP.

[0197] Of course, the terminal may also select the fourth main anchor point BWP based on its own implementation, such as random selection.

[0198] Optionally, for different terminals, the specific contents of the first selection criterion and the second selection criterion may be different.

[0199] Optionally, the priorities of the various items in the first selection criterion and the second selection criterion may be the same or different. If the priorities are different, the terminal selects according to the first selection criterion or the second selection criterion in descending order of priority. For example, if the first selection criterion includes: defined first BWP information and the terminal's identifier, and the priority of the defined first BWP information is higher than the priority of the terminal's identifier, the terminal selects the third primary anchor point BWP based on the order of the first BWP information and the terminal's identifier.

[0200] Optionally, in this embodiment, the method further includes:

[0201] The network device determines whether to send an NCD-SSB for the terminal on the second primary anchor point BWP based on at least one of the following:

[0202] whether a synchronization signal block SSB is sent on the adjacent main anchor point BWP of the second main anchor point BWP;

[0203] The interval between the center frequencies of the second main anchor point BWP and the adjacent main anchor point BWP;

[0204] The size of the second main anchor point BWP;

[0205] The transmission content supported by the second primary anchor point BWP.

[0206] In this way, for NCD-SSB and a second primary anchor point BWP, the network device will determine whether to send NCD-SSB for the terminal on this second primary anchor point BWP based on the above content.

[0207] In this embodiment, the adjacent primary anchor point BWP of a second primary anchor point BWP refers to a given SA BWP that is adjacent to the previous or next SA BWP in the frequency domain. For example, the resource indices of frequency domain units 0, 1, 2, 3, and 4 are arranged in ascending order. A given second primary anchor point BWP occupies frequency domain unit 3. The previous SABWP adjacent to this second primary anchor point BWP occupies frequency domain unit 2 or frequency domain units 1 and 2, and the next SABWP adjacent to this second primary anchor point BWP occupies frequency domain unit 4. It should be noted that the adjacent primary anchor point BWP of this second primary anchor point BWP can be either an SA BWP or an FA BWP.

[0208] When determining whether to send an NCD-SSB for a terminal on the second primary anchor point BWP based on whether an SSB is sent on an adjacent primary anchor point BWP of the second primary anchor point BWP, it is necessary to consider whether an SSB (including a CD-SSB or an NCD-SSB) is sent on an adjacent primary anchor point BWP of the second primary anchor point BWP. Optionally, if an SSB is not sent on an adjacent primary anchor point BWP of the second primary anchor point BWP, it is determined that an NCD-SSB is sent on the second primary anchor point BWP; if an SSB is sent on an adjacent primary anchor point BWP of the second primary anchor point BWP, it is determined that an NCD-SSB is not sent on the second primary anchor point BWP.

[0209] When determining whether to transmit an NCD-SSB for a terminal on the second primary anchor point BWP based on the center frequency interval between the second primary anchor point BWP and the adjacent primary anchor point BWP, the interval is optionally compared with a third threshold to determine whether to transmit an NCD-SSB for the terminal on the second primary anchor point BWP. If the interval is less than or equal to the third threshold, it is determined that the NCD-SSB is not transmitted on the second primary anchor point BWP, and the terminal may use the SSB (CD-SSB or NCD-SSB) of the adjacent SA BWP for uplink and downlink transmissions. If the interval is less than or equal to the third threshold, the NCD-SSB is transmitted on the second primary anchor point BWP, and the terminal may use the NCD-SSB on the second primary anchor point BWP for uplink and downlink transmissions. Here, the third threshold is a preconfigured or defined interval threshold.

[0210] If determining whether to transmit an NCD-SSB for a terminal on the second primary anchor point BWP is based on the size of the second primary anchor point BWP, the size of the second primary anchor point BWP must be compared with the size of the frequency domain resources required for transmitting the NCD-SSB. If the size of the second primary anchor point BWP satisfies the size of the frequency domain resources required for transmitting the NCD-SSB, the NCD-SSB is transmitted on the second primary anchor point BWP. If the size of the second primary anchor point BWP does not meet the size of the frequency domain resources required for transmitting the NCD-SSB, the NCD-SSB is not transmitted on the second primary anchor point BWP. For example, if the size of the second primary anchor point BWP is 3 MHz and the size of the frequency domain resources required for transmitting the NCD-SSB is 5 MHz, the NCD-SSB is not transmitted on the second primary anchor point BWP. In the case where NCD-SSB is not sent on the second main anchor point BWP, optionally, the terminal expects SSB (CD-SSB or NCD-SSB) to be sent on the adjacent SA BWP of the second main anchor point BWP and uses the SSB for uplink and downlink transmission; or the terminal expects TRS to be sent on the second main anchor point BWP and uses the TRS for uplink and downlink transmission on the second main anchor point BWP.

[0211] Determining whether to send the NCD-SSB for the terminal on the second primary anchor point BWP based on the transmission content supported by the second primary anchor point BWP may include:

[0212] If the second primary anchor point BWP supports monitoring of paging information and / or PEI, the second primary anchor point BWP sends CD-SSB or NCD-SSB to the terminal. Optionally, the terminal can use NCD-SSB to monitor paging information on the second primary anchor point BWP;

[0213] If the second primary anchor point BWP does not support monitoring of paging information but supports initial access or PRACH-based small data transmission, the NCD-SSB may not be sent on the second primary anchor point BWP. In this case, the terminal is deemed not to need to measure the SSB during the initial access or PRACH-based small data transmission on the second primary anchor point BWP, or, before performing initial access or PRACH-based small data transmission on the second primary anchor point BWP, the terminal measures the SSB and / or TRS on other primary anchor point BWPs containing SSB (CD-SSB or NCD-SSB) / TRS, and the measurement result is valid during the initial access or PRACH-based small data transmission on the second primary anchor point BWP, or the terminal uses the measurement result for initial access or PRACH-based small data transmission on the second primary anchor point BWP.

[0214] Of course, the second primary anchor point BWP supports monitoring of paging information and / or PEI. The second primary anchor point BWP can send TRS to the terminal, and the terminal can use TRS to monitor paging information. If the second primary anchor point BWP does not support monitoring of paging information and supports initial access or small data transmission based on PRACH, TRS may not be sent on the second primary anchor point BWP.

[0215] It should be noted that in this embodiment, SSB or TRS is used for uplink and downlink transmission, that is, the measurement results of SSB or TRS are used to maintain uplink and downlink synchronization, judge the channel quality, determine the beams used for uplink and downlink transmission, quasi-co-location (QCL), etc.

[0216] Optionally, in this embodiment, the configuration information of the serving cell, the configuration information of the first main anchor point BWP, and the configuration information of the second main anchor point BWP are not limited to the above description, and may also include other content. For example, the configuration information of the first main anchor point BWP also includes the frequency domain position of the first main anchor point BWP, the frequency domain resource size of the first main anchor point BWP, and the resources and parameters for uplink and downlink transmission of the terminal on the first main anchor point BWP.

[0217] Optionally, the configuration information of the serving cell, the configuration information of the first primary anchor point BWP, and the configuration information of the second primary anchor point BWP may be carried by system information or dedicated information.

[0218] For example, the network device sends system information carrying at least one of the configuration information of the serving cell, the configuration information of the first main anchor point BWP, and the configuration information of the second main anchor point BWP, and the terminal receives the system information and uses the configuration information carried by the system information to perform First UL Tx, which is used for the UE to establish an RRC connection or small data transmission with the network device running on the cell / anchor BWP.

[0219] If both the system information and the dedicated information carry the above configuration information, the terminal preferentially uses the configuration information carried in the dedicated information for First UL Tx. Of course, the configuration information carried in the system information and the dedicated information may be different, such as including different frequency domain units.

[0220] Among them, for the configuration information of the primary anchor point BWP, the frequency resources of the anchor RBS / RBG configured by the system information and the dedicated information can be different, or, if there are multiple anchor RBS / RBGs configured by the system information and the dedicated information, at least one anchor RBS / RBG should be the same or common.

[0221] It should be noted that, in this embodiment, the state of the terminal initiating the PRACH includes at least one of the following: an idle / inactive state; and a connected state.

[0222] The following describes the application of the embodiments of the present application in conjunction with specific scenarios:

[0223] A terminal in the RRC-IDLE / INACTIVE state first detects the CD-SSB on the synchronization raster and, based on the CD-SSB, determines the system information for scheduling the first primary anchor point (BWP). This system information includes the configuration information of the serving cell and the configuration information of the first primary anchor point (BWP). The terminal decodes the system information of the first primary anchor point (BWP). The serving cell configuration information determines the cell composed of multiple frequency domain units. The configuration information of the first primary anchor point (BWP) determines the frequency domain location and frequency domain resource size of the first primary anchor point (BWP), as well as the resources and parameters for the terminal's uplink and downlink transmissions. The terminal then receives the configuration information of the second primary anchor point (BWP) on the first primary anchor point (BWP). This configuration information includes at least an indication of the purpose of the second primary anchor point (BWP).

[0224] When there are multiple second main anchor points BWP, the uses of the multiple second main anchor points BWP include at least one of the following:

[0225] -Multiple secondary anchor points BWP are used to serve different terminal types, such as the secondary anchor point BWP#1 for non-RedCap devices (UE), the secondary anchor point BWP#2 for RedCap devices, and the secondary anchor point BWP#3 for Ambient IoT devices.

[0226] - Multiple secondary anchor points (BWPs) are used for different use cases, such as BWP#1 for the NTN and BWP#2 for the terrestrial network (TN). These multiple BWPs can also be used for different service types, such as BWP#1 for multicast broadcast services and BWP#2 for small data transmission services.

[0227] -The multiple secondary anchor points BWPs can also be used to balance the offload of different uplink and downlink resources / services. For example, the secondary anchor point BWP#1 is used to transmit paging information / PEI, offloading the load of paging information / PEI on the first primary anchor point BWP#0, while the secondary anchor point BWP#2 is used for initial cell access, offloading the load of uplink and downlink resources required for initial access on the first primary anchor point BWP#0.

[0228] The terminal determines the purpose, frequency domain position, frequency domain resource size of the relevant second main anchor point BWP, the first feature / function associated with the second main anchor point BWP, and the transmission target associated with the first feature / function by decoding the configuration information of the second main anchor point BWP.

[0229] The terminal selects the corresponding second main anchor point BWP for related uplink and downlink transmission and reception based on the first selection criterion, or the first selection criterion and the second selection criterion, such as the network's indication information, its own capabilities (such as the supported bandwidth size, whether SSB is required), and the supported first feature / function.

[0230] Example 1: Assume that a serving cell for a terminal, as determined by the network device, consists of four non-contiguous frequency domain units, denoted as RB sets #0, #1, #2, and #3. RB set #0 is the first primary anchor point BWP, denoted as FA BWP #0, with a BWP size of 20 MHz. RB sets #1 and #2 are the second primary anchor points BWP, denoted as SA BWP #1 and SA BWP #2, with SA BWP #1 and SA BWP #2 having a size of 3 MHz and 10 MHz, respectively. RB set #3 is not a primary anchor point BWP, but rather a standard BWP. The SSB size is 5 MHz. FA BWP #0 includes CD-SSBs, supporting paging (paging information), broadcast information, and initial access-related transmission and reception (transmission objects during the initial access process). SA BWP #1 does not include any SSBs and supports initial access-related transmission and reception, as well as the sending of broadcast information. SA BWP #2 includes NCD-SSBs, supporting only initial access-related transmission and reception, and small data transmission-related transmission (transmission objects during the small data transmission process). There are two IDLE / INACTIVE terminals, denoted as UE#1 and UE#2. UE#1's receiving / transmitting bandwidth capability (supported bandwidth size) is 5MHz, and it is contracted to receive broadcast information; UE#2's receiving / transmitting bandwidth capability is 100MHz, and it is not contracted to receive broadcast information.

[0231] 1. UE#1 and UE#2 need to or can only monitor paging information / PEI on FA BWP#0 associated with CD-SSB.

[0232] 2. For UE#1,

[0233] According to the time location of broadcast information transmission, UE#1 needs to switch from FA BWP#0 to SA BWP#1 to receive broadcast information; according to the time location of paging information / PEI transmission, UE#1 needs to switch from SA BWP#1 to FA BWP#0 to monitor paging information / PEI; in other words, when UE#1 receives the first type of broadcast information on SA BWP#1, it switches to FA BWP#0.

[0234] Optionally, UE#1 does not expect the time position of monitoring paging information / PEI to overlap with the time position of receiving the first type of broadcast information; or allows the time position of monitoring paging information / PEI to overlap (conflict) with the time position of receiving the first type of broadcast information. When a conflict occurs, UE#1 gives priority to receiving the paging information / PEI.

[0235] When UE#1 receives the initial access triggered by paging on FA BWP#0, UE#1's receive / transmit bandwidth capability is 5 MHz, so it can only select SA BWP#1 for initial access. UE#1 does not need to measure SSB during the initial access process of SA BWP#1.

[0236] 3. For UE#2,

[0237] When UE#2 receives the initial access triggered by Paging on FA BWP#0, the receiving / transmitting bandwidth capability of UE#1 is 100 MHz, so FA BWP#0, SA BWP#1 and SA BWP#2 are available for selection.

[0238] UE#2 selects SA BWP#2 for initial access based on the first selection criterion, such as (UE_ID mod N), N = (total number of FA BWPs + total number of SA BWPs) = 3, then (UE_ID mod N) = (2 mod 3) = 2. Or

[0239] UE#2 selects the SA BWP based on the first selection criteria, such as the network device's indication that the SA BWP is selected or the defined first BWP information prioritizes the SA BWP. UE#2 then selects SA BWP#1 and SA BWP#2 based on the second selection criteria, such as SA BWP#2 having a larger bandwidth or SA BWP#2 having SSB. UE#2 then selects SA BWP#2 for initial access based on the second selection criteria, such as SA BWP#2 having a larger bandwidth or SA BWP#2 having SSB.

[0240] When UE#2 receives a small data transmission triggered by Paging on FA BWP#0, or UE#2 autonomously needs to perform uplink small data transmission, since only SA BWP#2 supports small data transmission, UE#2 selects SA BWP#2 for small data transmission.

[0241] Example 2: Assume that a serving cell consists of four non-contiguous frequency domain units, denoted as RB sets #0, #1, #2, and #3. RB set #0 is the first primary anchor point BWP, denoted as FA BWP #0, and its size is 5 MHz. RB set #1 and RB set #2 are the second primary anchor point BWPs, denoted as SA BWP #1 and SA BWP #2, with SA BWP #1 and SA BWP #2 of 10 MHz and 20 MHz, respectively. RB set #3 is not a primary anchor point BWP, but a normal BWP. The SSB size is 5 MHz. FA BWP#0 includes CD-SSB, supporting paging (paging information), broadcast information, and initial access-related transmission and reception (transmission objects during the initial access process). SA BWP#1 does not include any SSB and supports initial access-related transmission and reception, as well as transmission and reception related to small data transmission (transmission objects during the small data transmission process). SA BWP#2 includes NCD-SSB, supporting paging, initial access for low-capability devices, and transmission related to small data transmission (transmission objects during the initial access process, transmission objects during the small data transmission process). There are three terminals, denoted as UE#1, UE#2, and UE#3. UE#1 has a receive / transmit bandwidth capability of 5 MHz and is an IoT device or lower-capability device. UE#2 has a receive / transmit bandwidth capability of 20 MHz and is a RedCap device or low-capability device. UE#3 has a receive / transmit bandwidth capability of 100 MHz and is an eMBB device or high-capability device.

[0242] 1. For UE#1, its receiving / transmitting bandwidth capability is 5 MHz, and it can only perform paging, broadcast information, and initial access / random access-related transmission and reception in FA BWP#0.

[0243] 2. For UE#2 and UE#3, it is necessary to determine whether to monitor paging / PEI on FA BWP#0 or SA BWP#2.

[0244] According to the first selection criterion, if paging information / PEI related to RedCap is configured on FA BWP#0 and paging information / PEI related to eMBB is configured on SA BWP#2, UE#2 chooses to monitor paging / PEI on FA BWP#0 and UE#3 chooses to monitor paging / PEI on SA BWP#2.

[0245] 3. For UE#2 and UE#3, when initial access is required, it is necessary to determine whether to perform initial access on FA BWP#0, SA BWP#1, and SA BWP#2.

[0246] UE#2 is a low-capability terminal and requires SSB. Therefore, according to the first selection criterion, FA BWP#0 and SA BWP#2 are available. UE#2 then prioritizes SA BWP according to the second selection criterion. Therefore, UE#2 determines to perform initial access on SA BWP#2.

[0247] UE#3 is a high-capability terminal and may not require SSB. Therefore, according to the first selection criterion, initial access is determined to be performed on FA BWP#0, SA BWP#1, and SA BWP#2. According to the second selection criterion, SA BWP is prioritized and the BWP with a smaller ID is selected. Therefore, UE#3 determines to perform initial access on SA BWP#1.

[0248] Example 3: Assume that a serving cell consists of four non-contiguous frequency domain units, denoted as RB sets #0, #1, #2, and #3. RB set #0 is the first primary anchor point BWP, denoted as FA BWP #0, and its size is 5 MHz. RB set #1 and RB set #2 are the second primary anchor point BWPs, denoted as SA BWP #1 and SA BWP #2, with SA BWP #1 and SA BWP #2 of 20 MHz and 50 MHz, respectively. RB set #3 is not a primary anchor point BWP, but a normal BWP. The SSB size is 5 MHz.

[0249] FA BWP#0 includes CD-SSB and supports only paging (paging information). SA BWP#1 includes NCD-SSB and supports transmission and reception related to initial access and small data transfer (transmission objects during initial access and small data transfer). SA BWP#2 does not include any SSB and supports transmission and reception related to initial access and small data transfer. There are two terminals, denoted as UE#1 and UE#2. UE#1 has a receive / transmit bandwidth capability of 20 MHz and is a RedCap device; UE#2 has a receive / transmit bandwidth capability of 100 MHz and is an eMBB device.

[0250] 1. UE#1 and UE#2 need to or can only monitor paging information / PEI on FA BWP#0 associated with CD-SSB.

[0251] 2. When UE#1 and UE#2 need to initiate initial access, SA BWP#1 and SA BWP#2 are not configured with initial access resources and transmission and reception parameters associated with the first feature / function, which means that the initial access resources on SA BWP#1 and SA BWP#2 do not restrict the devices used, that is, both UE#1 and UE#2 can use them.

[0252] For UE#1, its first selection criterion includes multiple items. UE#1 selects a primary anchor BWP according to the order of priority of the multiple items in the first selection criterion from highest to lowest. For example, UE#1 determines to use SA BWP#1 that includes SSB based on the transmission target associated with at least one of the following items configured on the third primary anchor BWP in e): terminal type, terminal capability, service type, and d) supported SSB or TRS (supported transmission target).

[0253] For UE#2, its first selection criterion includes e) the configuration of a transmission target associated with at least one of the following: terminal type, terminal capabilities, and service type on the third primary anchor BWP, and c) the size of the BWP (preferably, the size of the third primary anchor BWP is less than or equal to the bandwidth supported by the terminal). The second selection criterion includes c) the size of the BWP (preferably, the BWP with the largest bandwidth). UE#2 selects a primary anchor BWP based on the priorities in e) and c) of the first selection criterion, from highest to lowest. If both SA BWP#1 and SA BWP#2 meet these criteria, UE#2 then selects SA BWP#2 based on c) the BWP with the largest bandwidth, as specified in the second selection criterion.

[0254] In summary, the network equipment determines a flexible service cell for the terminal. On the network side, from the perspective of L1 / L2 / L3 signaling, processes and cell management, it can flexibly and efficiently utilize adjacent continuous and / or non-contiguous spectrum to improve system capacity and coverage. On the terminal side, the aggregated spectrum can increase the user-perceived data rate, save energy, reduce latency, and improve coverage.

[0255] The first main anchor point BWP and the second main anchor point BWP are determined, and the terminal selects the main anchor point BWP for related uplink and downlink transmission according to the first selection criterion, or the first selection criterion and the second selection criterion, which can achieve the following benefits:

[0256] Load balancing: terminals are distributed across different secondary anchor points (BWPs) and will not be crowded at the primary anchor point (BWP), causing resource shortages.

[0257] Multiple second main anchor points BWP can better support devices with different capabilities and different application scenarios, such as TN, NTN, etc.
