[0057] For ease of understanding, some contents involved in the embodiments of the present application are described below:

[0058] 1. Reasons and benefits of introducing one flexible cell

[0059] 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.

[0060] 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, a flexible cell, which can contain fragmented spectrum resources, aims to efficiently and flexibly utilize these fragmented continuous or discontinuous spectrums.

[0061] 2. 5G non-RedCap initial bandwidth part (BWP) and resource set 0 (CORESET#0)

[0062] The initial uplink and downlink BWP, namely the initial downlink BWP (Initial DL BWP) and the initial uplink BWP (Initial ULBWP) will be configured in the system information block (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 in the initial access process, such as the reception of SIB1, the reception of the random access response (Rach Access Response, RAR) and Msg4 in the random access process, and the transmission of the preamble and Msg3.

[0063] Terminal side process of cell search / initial access process:

[0064] 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;

[0065] 2. Monitor the downlink control information (DCI) of SIB1 in CORESET#0;

[0066] 3. Decode SIB1 and obtain the control resource set (ControlResource Set, CORESET) of initial DL / UL BWP and RAR / msg4 DCI.

[0067] CORESET: defines 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.

[0068] The PDCCH channel in NR has multiple search spaces, including common search spaces and UE-specific search spaces, as shown in the following table:

[0069]

[0070] 3. 5G RedCap separate initial DL / UL BWP

[0071] 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, then the network can configure an additional / independent initial BWP for the redcap UE so that the bandwidth of the BWP is within the capability of the redcap UE.

[0072] In addition, since the number of receiving antennas of redcap UE is less than that of ordinary UE, the receiving performance is not as good as that of ordinary UE, which may cause the network to use more overhead and more resources to transmit to redcap UE. In this way, even if the bandwidth of the BWP configured by the network is within the capacity of redcap UE, if the network uses the same BWP to transmit to ordinary UE and redcap UE, the load on the BWP is too large, which may cause congestion for ordinary terminal transmission. Therefore, the new redcap work item made the following conclusions:

[0073] 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,

[0074] 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.

[0075] Redcap UEs in RRC_IDLE and RRC_INACTIVE 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 are not further considered to monitor paging in the initial BWP associated with CD-SSB.

[0076] 2. For the active DL BWP configured by the redcap UE of RRC_CONNECTED, if it does not include the CD-SSB and the entire CORESET#0, then

[0077] A Basic Capability RedCap UE expects the active DL BWP to contain the NCD-SSB for the serving cell but not CORESET#0 / SIB.

[0078] A RedCap UE with higher capability may operate on an active DL BWP without any SSB.

[0079] Note: The NCD-SSB cycle does not need to be configured the same as the CD-SSB cycle.

[0080] Note: The period of NCD-SSB should not be less than that of CD-SSB.

[0081] 4. Spectrum Sharing among Different Wireless Communication Systems

[0082] Operators often operate multiple networks at the same time. After 5G is deployed, there will be scenarios where 2G, 3G, 4G, and 5G are operating simultaneously. With the increasing demand for mobile broadband network traffic, operators are refarming 2G / 3G networks to 4G, and then refarming 4G to 5G. In traditional operators' multi-standard networks, each standard needs to occupy a certain amount of spectrum resources. Since each standard has exclusive spectrum, if the spectrum between different standards cannot be shared during peak hours, it will lead to serious waste of spectrum resources. At present, the 4G and 5G spectrum sharing project has been established. This technology can realize the on-demand and dynamic allocation of spectrum resources for 4G or 5G in the same frequency band.

[0083] The method in the embodiment of the present application is applicable to 5G, 6G and subsequent evolution communication systems.

[0084] The following, in combination 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.

[0085] like Figure 2 As shown, the transmission configuration method of the embodiment of the present application includes:

[0086] Step 201: A network device determines configuration information of a serving cell of a terminal, where the serving cell includes a plurality of frequency domain units configured for the terminal, and at least two frequency domain units are non-contiguous in the frequency domain;

[0087] 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.

[0088] 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 for 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, processes 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.

[0089] 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 Group, RBG), and BWP.

[0101] The first information includes that the difference in downlink reception time of different frequency domain units satisfies the first time range, which means that for the multiple frequency domain units included in the service cell, the difference in downlink reception time of any two frequency domain units satisfies the first time range T1_difference. Optionally, T1_difference can be determined based on a set value, such as a set value of 260ns, then T1_difference = ±260ns.

[0102] Among them, the first information includes that the difference in uplink timing advance of different frequency domain units satisfies the second time range, that is, for the multiple frequency domain units included in the service cell, the difference in uplink timing advance of any two frequency domain units satisfies the second time range T2_difference.

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

[0125] Optionally, in this embodiment, an interval between adjacent non-continuous frequency domain units in the multiple frequency domain units is less than or equal to a second threshold.

[0126] Thus, for the multiple frequency domain units included in the service cell, in the discontinuous frequency domain units (i.e., non-continuous frequency domain units) in the multiple frequency domain units, the interval between adjacent discontinuous frequency domain units is less than or equal to the second threshold. The interval may also be referred to as a frequency offset or a gap. The second threshold is a preset interval threshold F_threshold.

[0141] 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.

[0146] The network device sends configuration information of the second primary anchor point BWP to the terminal;

[0147] 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.

[0148] That is, for the serving cell configured for the terminal, the network device will further determine the configuration information of the second anchor BWP (SA BWP) of the terminal and inform the terminal of the configuration information so that the terminal can perform subsequent transmission. Of course, the network device configures one or more SA BWPs for the terminal.

[0149] 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.

[0150] Optionally, the configuration information of the second main anchor point BWP includes at least one of the following: the frequency domain position of the second main anchor point BWP, the frequency domain resource size, the first characteristic / function associated with the second main anchor point BWP, and the transmission target associated with the first characteristic / function.

[0152] Non-cell defined synchronization signal block NCD-SSB, TRS, system information, broadcast information, transmission objects during initial access, transmission objects during random access, transmission objects during small data transmission, paging information, PEI, terminal group common information, user data.

[0153] The first and second objectives are described in detail as follows:

[0154] 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 Type0ACSS.

[0155] The broadcast information may be broadcast information (broadcast) scheduled by PDCCH, and the PDCCH is received through Type0BCSS.

[0157] Among them, PEI can be received through Type2ACSS.

[0158] The terminal group common information may be DCI scheduled, and the DCI is received via Type3 CSS.

[0159] The user data may be scheduled by a PDCCH, which is received by a UE SS.

[0160] Therefore, in this embodiment, the first target or the second target may also include at least one of the PDCCH and DCI that schedule the above information.

[0161] 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.

[0162] Among them, the first uplink transmission object is also called the first uplink transmission (First UL Tx), including at least one of the following: PRACH, message A (MSGA), small data transmission based on authorization (Small Data Transmission-Configured Grant, SDT-CG), PUCCH.

[0163] Here, PRACH may 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), PRACH triggered by PDCCH order. MSGA includes MSGA PRACH and MSGA PUSCH. PUCCH is a PUCCH carrying HARQ-ACK information transmitted on the cell common PUCCH.

[0164] 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, MSGB.

[0165] 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.

[0166] Optionally, the terminal selects a third main anchor point BWP based on at least one of the following:

[0167] Indication information of the network device;

[0168] The first BWP information defined;

[0169] an identification (ID) of the terminal;

[0170] The size of the BWP;

[0171] 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.

[0172] Here, the information used by the terminal to select the third primary anchor point BWP may be referred to as a first selection criterion.

[0173] Among them, the indication information of the network device is used to indicate which one of FABWP and SA BWP the terminal selects as the third main anchor point BWP. For example, if the indication information indicates FA BWP, the terminal selects FA BWP as the third main anchor point BWP. For example, if the indication information indicates that the third main anchor point BWP is SA BWP that transmits SSB or TRS, the terminal selects SA BWP that transmits SSB or TRS as the third main anchor point BWP.

[0174] 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 BWP ID; if the first BWP information includes the transmission SSB or TRS of the BWP, the terminal selects the SABWP or FA BWP that transmits SSB or TRS as the third main anchor point BWP.

[0175] The terminal identifier can be used to determine the identifier of the third primary anchor point BWP, such as determining the ID of the third primary anchor point BWP by (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.

[0176] 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 less than or equal to the size of the BWP supported by the terminal as the third main anchor point BWP.

[0177] Among them, the supported transmission target can be understood as the transmission target of the desired third main 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 main anchor point BWP. Of course, the supported transmission target can be a limitation for SA BWP, and the terminal can select a SA BWP that supports transmission of SSB or TRS as the third main anchor point BWP.

[0178] 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.

[0179] In this embodiment, the transmission target includes at least one of the following: broadcast information, a transmission object in an initial access process, a transmission object in a random access process, a transmission object in a small data transmission process, paging information, and PEI. In this way, the third primary anchor point BWP that the terminal expects to select can be a BWP configured to receive broadcast information associated with different terminal types.

[0180] 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), RedCap UE, 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 bands, and downlink processing capabilities. 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).

[0181] Of course, the terminal may also select the third main anchor point BWP based on its own implementation, such as random selection.

[0182] 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:

[0183] Broadcast information, transmission objects during initial access, transmission objects during random access, transmission objects during small data transmission, paging information, PEI.

[0184] 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:

[0185] The second BWP information defined;

[0186] BWP logo;

[0187] an identification of the terminal;

[0188] The size of the BWP;

[0189] Supported transfer targets.

[0190] Here, the plurality of third primary anchor points BWP may be a FA BWP and at least one SA BWP, or only a plurality of SABWPs. The information used by the terminal to select the fourth primary anchor point BWP may be referred to as a second selection criterion.

[0191] Among them, the defined second BWP information is the information of the BWP that the terminal preferentially selects among multiple third main anchor point BWPs as specified by the protocol. For example, if the first BWP information includes the ID of the BWP, the terminal selects the corresponding BWP as the fourth main anchor point BWP according to the BWP ID; if the first BWP information includes the transmission SSB or TRS of the BWP, the terminal selects the SA BWP or FABWP that transmits SSB or TRS as the fourth main anchor point BWP.

[0192] 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.

[0193] The identifier of the terminal may be used to determine the identifier of the fourth primary anchor point BWP, such as determining the ID of the fourth primary anchor point BWP by (UE_ID mod N) or (UE_ID mod N) + 1. Wherein N = (the total number of FA BWPs + the total number of SA BWPs), or N = the total number of SABWPs, 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.

[0194] Among them, the size of 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 size of all third main anchor point BWPs; it can also be understood as the size of SA BWP. For example, the terminal selects the SA BWP with the largest or smallest bandwidth as the fourth main anchor point BWP.

[0195] Among them, the supported transmission target can be understood as the transmission target of the desired fourth main anchor point BWP. For example, if the supported transmission target is SSB or TRS, the terminal can select the third main anchor point BWP supporting the transmission of SSB or TRS as the fourth main anchor point BWP. Of course, the supported transmission target can be a limitation for SA BWP, and the terminal can select SA BWP supporting the transmission of SSB or TRS as the fourth main anchor point BWP.

[0196] Of course, the terminal may also select the fourth main anchor point BWP based on its own implementation, such as random selection.

[0197] Optionally, for different terminals, specific contents of the first selection criterion and the second selection criterion may be different.

[0198] Optionally, the priorities of the various contents in the first selection criterion and the second selection criterion may be the same or different. If the priorities are different, the terminal selects in order of priority from high to low when selecting according to the first selection criterion or the second selection criterion. For example, the first selection criterion includes: the defined first BWP information, and the terminal identifier, wherein the priority of the defined first BWP information is higher than the priority of the terminal identifier, then the terminal selects the third main anchor point BWP based on the first BWP information and the terminal identifier sequence.

[0199] Optionally, in this embodiment, the method further includes:

[0200] The network device determines whether to send the NCD-SSB for the terminal on the second primary anchor point BWP based on at least one of the following:

[0201] Whether a synchronization signal block SSB is sent on the adjacent main anchor point BWP of the second main anchor point BWP;

[0202] The interval between the center frequencies of the second main anchor point BWP and the adjacent main anchor point BWP;

[0203] The size of the second main anchor point BWP;

[0204] The transmission content supported by the second primary anchor point BWP.

[0205] In this way, for NCD-SSB and a second main anchor point BWP, the network device will determine whether to send NCD-SSB for the terminal on this second main anchor point BWP based on the above content.

[0206] In this embodiment, the adjacent main anchor point BWP of the second main anchor point BWP refers to a given SA BWP, the SA BWP is adjacent to the previous or next SA BWP in the frequency domain resources. For example: the resource indexes occupied by frequency domain units 0, 1, 2, 3, and 4 in the frequency domain are arranged in ascending order. A given second main anchor point BWP occupies frequency domain unit 3, the adjacent previous SABWP of the second main anchor point BWP occupies frequency domain unit 2 or frequency domain units 1 and 2, and the adjacent next SA BWP of the second main anchor point BWP occupies frequency domain unit 4. It should be noted that the adjacent main anchor point BWP of the second main anchor point BWP can be an SA BWP or a FA BWP.

[0207] When determining whether to send NCD-SSB for the terminal on the second main anchor point BWP based on whether SSB is sent on the adjacent main anchor point BWP of the second main anchor point BWP, it is necessary to consider whether SSB (the SSB includes CD-SSB or NCD-SSB) is sent on the adjacent main anchor point BWP of the second main anchor point BWP. Optionally, if SSB is not sent on the adjacent main anchor point BWP of the second main anchor point BWP, it is determined to send NCD-SSB on the second main anchor point BWP; if SSB is sent on the adjacent main anchor point BWP of the second main anchor point BWP, it is determined not to send NCD-SSB on the second main anchor point BWP.

[0208] Among them, based on the interval between the center frequencies of the second main anchor point BWP and the adjacent main anchor point BWP, when determining whether to send NCD-SSB to the terminal on this second main anchor point BWP, optionally, the interval is compared with the third threshold to determine whether to send NCD-SSB to the terminal on the second main anchor point BWP. If the interval is less than or equal to the third threshold, it is determined that the NCD-SSB is not sent on the second main anchor point BWP, and the terminal can use the SSB (CD-SSB or NCD-SSB) of the adjacent SA BWP for uplink and downlink transmission; if the interval is less than or equal to the third threshold, the NCD-SSB is sent on the second main anchor point BWP, and the terminal can use the NCD-SSB on the second main anchor point BWP for uplink and downlink transmission. Here, the third threshold is a preconfigured or defined interval threshold.

[0209] Among them, if it is determined whether to send NCD-SSB for the terminal on the second main anchor point BWP based on the size of the second main anchor point BWP, it is necessary to compare the size of the second main anchor point BWP with the size of the frequency domain resources required for sending NCD-SSB. When the size of the second main anchor point BWP meets the size of the frequency domain resources required for sending NCD-SSB, NCD-SSB is sent on the second main anchor point BWP; when the size of the second main anchor point BWP does not meet the size of the frequency domain resources required for sending NCD-SSB, NCD-SSB is not sent on the second main anchor point BWP. For example, if the size of the second main anchor point BWP is 3MHz, and the size of the frequency domain resources required for NCD-SSB is 5MHz, NCD-SSB is not sent on the second main anchor point BWP. When 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.

[0210] The 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:

[0211] If the second main anchor point BWP supports monitoring of paging information and / or PEI, the second main 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 main anchor point BWP;

[0212] If the second main anchor point BWP does not support monitoring of paging information, but supports initial access or small data transmission based on PRACH, then NCD-SSB may not be sent on the second main anchor point BWP. At this time, the terminal is considered not to need to measure SSB during the initial access or small data transmission based on PRACH on the second main anchor point BWP, or the terminal measures SSB and / or TRS on other main anchor point BWPs containing SSB (CD-SSB or NCD-SSB) / TRS before performing initial access or small data transmission based on PRACH on the second main anchor point BWP, and the measurement result is valid during the initial access or small data transmission based on PRACH of the terminal on the second main anchor point BWP, or the terminal uses the measurement result to perform initial access or small data transmission based on PRACH on the second main anchor point BWP.

[0213] Of course, the second main anchor point BWP supports the monitoring of paging information and / or PEI, and the second main anchor point BWP can send TRS to the terminal, and the terminal can use TRS to monitor the paging information. The second main anchor point BWP does not support the monitoring of paging information, but supports initial access or small data transmission based on PRACH, so the second main anchor point BWP may not send TRS.

[0214] 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 channel quality, determine the beams used for uplink and downlink transmission, quasi co-location (QCL), etc.

[0215] Optionally, in this embodiment, the configuration information of the service 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, such as 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, the resources and parameters for uplink and downlink transmission of the terminal on the first main anchor point BWP, etc.

[0216] 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.

[0217] For example, the network device sends system information carrying the configuration information of the serving cell, the configuration information of the first main anchor point BWP, and at least one of 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.

[0218] If both the system information and the dedicated information carry the above configuration information, the terminal preferentially uses the configuration information carried by the dedicated information for First UL Tx. Of course, the configuration information carried by the system information and the dedicated information may be different, such as including different frequency domain units.

[0219] 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 may 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.

[0220] It should be noted that, in this embodiment, the state of the terminal initiating the PRACH includes at least one of the following: a non-connected state (idle / inactive); a connected state (connected).

[0221] The following describes the application of the embodiments of the present application in combination with specific scenarios:

[0222] The terminal in the RRC-IDLE / INACTIVE state first detects CD-SSB on the synchronization raster, and determines the system information for scheduling the first main anchor point BWP according to CD-SSB, and the system information includes the configuration information of the serving cell and the configuration information of the first main anchor point BWP. The terminal decodes the system information of the first main anchor point BWP, and determines the cell (cell) formed by the aggregation of multiple frequency domain units from the configuration information of the serving cell, and determines the frequency domain position and frequency domain resource size of the first main anchor point BWP, as well as the resources and parameters for the terminal to perform uplink and downlink transmission from the configuration information of the first main anchor point BWP. The terminal receives the configuration information of the second main anchor point BWP on the first main anchor point BWP, and the configuration information at least includes the usage indication of the second main anchor point BWP.

[0223] 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:

[0224] -Multiple second main anchor points BWP are used to serve different terminal types, such as the second main anchor point BWP#1 for non-RedCap devices (UE), the second main anchor point BWP#2 for RedCap devices, the second main anchor point BWP#3 for Ambient IoT devices, etc.

[0225] - Multiple second main anchor points BWP are used for different use cases, such as the second main anchor point BWP#1 for NTN, the second main anchor point BWP#2 for terrestrial network (TN), etc. The multiple second main anchor points BWP can also be used for different service types, such as the second main anchor point BWP#1 for multicast broadcast service, and the second main anchor point BWP#2 for small data transmission service.

[0226] -The multiple second main anchor points BWP can also be used to balance the offload of different uplink and downlink resources / services. For example, the second main anchor point BWP#1 is used to transmit paging information / PEI, unloading the load of paging information / PEI on the first main anchor point BWP#0, while the second main anchor point BWP#2 is used for initial access to the cell, unloading the load of uplink and downlink resources required for initial access on the first main anchor point BWP#0.

[0227] The terminal determines the purpose, frequency domain position, frequency domain resource size of the relevant second main anchor point BWP, the first characteristic / function associated with the second main anchor point BWP, and the transmission target associated with the first characteristic / function by decoding the configuration information of the second main anchor point BWP.

[0228] The terminal selects the corresponding second main anchor point BWP for related uplink and downlink transmission and reception according to 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.

[0229] Example 1: Assume that a service cell of a terminal determined by a network device is composed of 4 non-contiguous frequency domain units, denoted as RB set#0, #1, #2, and #3; RB set#0 is the first main anchor point BWP, denoted as FA BWP#0, and its size (the size of BWP) is 20MHz; RB set#1 and RB set#2 are the second main anchor point BWP, denoted as SA BWP#1 and SA BWP#2, the size of SA BWP#1 is 3MHz, and the size of SA BWP#2 is 10MH; RB set#3 is not a main anchor point BWP, that is, a common BWP. The SSB size is 5MHz. FABWP#0 includes CD-SSB, supports 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, supports initial access-related transmission and reception, and the sending of broadcast information; SA BWP#2 includes NCD-SSB, and only supports initial access-related transmission and reception, and small data transmission-related transmission (transmission objects during small data transmission). There are two IDLE / INACTIVE terminals, denoted as UE#1 and UE#2. The receiving / transmitting bandwidth capability (supported bandwidth size) of UE#1 is 5MHz, and it is contracted to receive broadcast information; the receiving / transmitting bandwidth capability of UE#2 is 100MHz, and it is not contracted to receive broadcast information.

[0230] 1. UE#1 and UE#2 need to or can only monitor paging information / PEI on FA BWP#0 associated with CD-SSB.

[0231] 2. For UE#1,

[0232] According to the time position of sending broadcast information, UE#1 needs to switch from FA BWP#0 to SA BWP#1 to receive broadcast information; according to the time position of sending paging information / PEI, UE#1 needs to switch from SA BWP#1 to FA BWP#0 to monitor paging information / PEI; or in other words, when UE#1 receives the first type of broadcast information on SA BWP#1, it switches to FA BWP#0.

[0233] Optionally, UE#1 does not expect the time position for monitoring paging information / PEI to overlap with the time position for receiving the first type of broadcast information; or allows the time position for monitoring paging information / PEI to overlap (conflict) with the time position for receiving the first type of broadcast information. When a conflict occurs, UE#1 gives priority to the reception of paging information / PEI.

[0234] When UE#1 receives the initial access triggered by Paging on FA BWP#0, the receiving / transmitting bandwidth capability of UE#1 is 5MHz, so only SA BWP#1 can be selected for initial access. During the initial access of SA BWP#1, UE#1 does not need to measure SSB.

[0235] 3. For UE#2,

[0236] 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.

[0237] 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

[0238] UE#2 selects SA BWP according to the first selection criteria, such as the indication information of the network device or the first defined BWP information giving priority to SA BWP, and then SA BWP#1 and SA BWP#2 are available for selection. UE#2 then selects SA BWP#2 for initial access according to the second selection criteria, such as the bandwidth of SABWP#2 is larger or there is SSB on SA BWP#2.

[0239] 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.

[0240] Example 2: Assume that a service cell is composed of 4 non-contiguous frequency domain units, denoted as RB set#0, #1, #2, #3; RB set#0 is the first main anchor point BWP, denoted as FA BWP#0, and its size is 5MHz; RB set#1 and RB set#2 are the second main anchor point BWP, denoted as SA BWP#1, SA BWP#2, SA BWP#1 size is 10MHz, SA BWP#2 size is 20MH; RBset#3 is not the main anchor point BWP, that is, a common BWP. The SSB size is 5MHz. FA BWP#0 includes CD-SSB, supports paging (paging information), broadcast information, initial access-related transmission and reception (transmission objects during initial access); SA BWP#1 does not include any SSB, supports initial access-related transmission and reception, small data transmission-related transmission and reception (transmission objects during small data transmission); SA BWP#2 includes NCD-SSB, supports paging, supports initial access of low-capability devices and transmission related to small data transmission (transmission objects during initial access, transmission objects during small data transmission). There are three terminals, denoted as UE#1, UE#2 and UE#3. UE#1 has a receiving / transmitting bandwidth capability of 5MHz, which is an IoT device or a lower-capability device; UE#2 has a receiving / transmitting bandwidth capability of 20MHz, which is a RedCap device or a low-capability device; UE#3 has a receiving / transmitting bandwidth capability of 100MHz, which is an eMBB device or a high-capability device.

[0241] 1. For UE#1, its receiving / transmitting bandwidth capability is 5 MHz, and it can only perform paging, broadcast information, initial access / random access related transmission and reception in FA BWP#0.

[0242] 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.

[0243] 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.

[0244] 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 SABWP#2.

[0245] UE#2 is a low-capability terminal and requires SSB, so 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, so UE#2 determines to make initial access on SA BWP#2.

[0246] UE#3 is a high-capability terminal and may not need SSB. Therefore, according to the first selection criterion, initial access is determined on FA BWP#0, SABWP#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 make initial access on SA BWP#1.

[0247] Example 3: Assume that a service cell is composed of 4 non-contiguous frequency domain units, denoted as RB set#0, #1, #2, #3; RB set#0 is the first main anchor point BWP, denoted as FA BWP#0, and its size is 5MHz; RB set#1 and RB set#2 are the second main anchor point BWP, denoted as SA BWP#1, SA BWP#2, SA BWP#1 size is 20MHz, SA BWP#2 size is 50MHz; RB set#3 is not the main anchor point BWP, that is, a common BWP. The SSB size is 5MHz.

[0248] FA BWP#0 includes CD-SSB and only supports paging (paging information); SA BWP#1 includes NCD-SSB and supports transmission and reception related to initial access and small data transmission (transmission objects during initial access and transmission objects during small data transmission); SA BWP#2 does not include any SSB and supports transmission and reception related to initial access and small data transmission. There are two terminals, denoted as UE#1 and UE#2. The receiving / transmitting bandwidth capability of UE#1 is 20MHz, RedCap equipment; the receiving / transmitting bandwidth capability of UE#2 is 100MHz, eMBB equipment.

[0249] 1. UE#1 and UE#2 need to or can only monitor paging information / PEI on FA BWP#0 associated with CD-SSB.

[0250] 2. When UE#1 and UE#2 need to initiate initial access, and 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, it 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.

[0251] For UE#1, its first selection criterion includes multiple items, and UE#1 selects the primary anchor point BWP in order from high to low priority of the multiple items in the first selection criterion. For example, UE#1 determines to use SABWP#1 including SSB according to the transmission target associated with at least one of the following items configured on the third primary anchor point BWP in e): terminal type, terminal capability, service type, and d) supported SSB or TRS (supported transmission target).

[0252] For UE#2, its first selection criterion includes e) the transmission target associated with at least one of the following items is configured on the third main anchor point BWP: terminal type, terminal capability, service type, and c) the size of the BWP (preferably the size of the third main anchor point BWP is less than or equal to the size of the bandwidth supported by the terminal), and the second selection criterion includes c) the size of the BWP (preferably the BWP with the largest bandwidth). UE#2 selects the main anchor point BWP in the order of e) and c) priority from high to low in the first selection criterion, and both SABWP#1 and SABWP#2 meet the conditions. UE#2 then selects SABWP#2 in accordance with c) the BWP with larger bandwidth in the second selection criterion.

[0253] In summary, the network equipment determines a flexible service cell for the terminal. On the network side, it can flexibly and efficiently utilize adjacent continuous and / or non-continuous spectrum from the perspective of L1 / L2 / L3 signaling, processes and cell management 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.

[0254] Among them, 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:

[0255] Load balancing: terminals are distributed to different second main anchor points BWP, instead of being crowded at the first main anchor point BWP, causing resource shortage;

[0256] Multiple second main anchor points BWP can better support devices of different capabilities and different application scenarios, such as TN, NTN, etc.
