For ease of explanation, in the embodiments of the present application, the above devices providing radio communication functionality to the terminal 20 are collectively referred to as access network devices.

[0040] The terminals 20 may be dispersed throughout the mobile communication system, and each terminal 20 may be stationary or mobile. The terminals 20 may also be referred to by those skilled in the art as mobile stations, user stations, mobile units, user units, wireless units, remote units, mobile devices, user equipment, wireless devices, wireless communication devices, remote devices, mobile user stations, access terminals, mobile terminals, wireless terminals, remote terminals, handheld devices, user agents, mobile clients, clients, or other suitable terms.

[0043] The communication system and business scenarios described in the embodiments of the present disclosure are intended to more clearly explain the technical solutions of the embodiments of the present disclosure, and are not intended to limit the technical solutions provided by the embodiments of the present disclosure. Those skilled in the art can know that with the evolution of communication systems and the emergence of new business scenarios, the technical solutions provided by the embodiments of the present disclosure can be similarly applied to similar technical problems.

[0044] In the communication system shown in FIG. 1, a terminal needs to complete initial access using a synchronization signal block (i.e., a synchronization signal and physical broadcast channel resource block (SSB, Synchronization Signal and PBCH Block)).

[0045] In the time domain, one SSB occupies four symbols (i.e., Orthogonal Frequency Division Multiplexing (OFDM) symbols), including one Primary Synchronized Signal (PSS) symbol, one Secondary Synchronized Signal (SSS) symbol, and two Physical Broadcast Channel (PBCH) symbols. Within an SSB, the symbols are numbered from 0 to 3. In the frequency domain, one SSB occupies 24 consecutive Resource Blocks (RBs). Each RB includes 12 subcarriers, and the subcarriers of the above 24 RBs are numbered in ascending order from 0 to 287, starting from the lowest numbered RB. For PSS and SSS, the resource maps to the middle 127th subcarrier, and for PBCH, the resource maps to the 288th subcarrier. The PSS, SSS, and PBCH have the same cyclic prefix (CP) length and subcarrier spacing, which can be configured to 15 kHz, 30 kHz, 120 kHz, and 240 kHz.

[0046] During initial access, the terminal first detects and receives a synchronization signal block, obtains a master information block (MIB) in the SSB, and obtains configuration information of control resource set 0 (CORESET#0) and search space (SS) of the physical downlink control channel (PDCCH) on which the terminal monitors and schedules other system messages (e.g., system information block 1 (SIB1, RMSI) from the MIB. According to the instructions of the MIB, the terminal can determine the frequency offset of CORESET#0 relative to the synchronization signal block and the size of the frequency resource occupied by CORESET#0, i.e., the number of RBs.

[0047] In order to accommodate different communication service needs, the communication system shown in Fig. 1 has two types of terminals, a first terminal and a second terminal, respectively. The capabilities of the two terminals are different, and illustratively, the bandwidth of the initial access band portion supported by the second terminal is larger than the bandwidth of the initial access band portion supported by the first terminal, that is, the access bandwidth capability of the second terminal exceeds the access bandwidth capability of the first terminal.

[0048] In the embodiment of the present disclosure, the first terminal may also be called a reduced capability new radio device (reduced capability NR device), a reduced capability user equipment (reduced capability UE), a capability restricted user equipment (capability restricted UE) or a new radio simplified device (NR-lite). Exemplarily, the first terminal may be some sensors of industrial Internet of Things, wireless video monitoring devices of smart cities, and wearable devices such as handling, wristwatches, health medical monitoring devices, etc. The second device may also be called a normal device such as a mobile terminal.

[0049] 2 is a flowchart of a method for determining an initial access bandwidth portion according to an exemplary embodiment. The method can be performed by the first terminal. Referring to FIG. 2, the method includes the following step 201:

[0050] In step 201, a first terminal determines a first initial access bandwidth portion according to a first rule, the first initial access bandwidth portion not exceeding an access bandwidth capability of the first terminal; The first a terminal that determines a second initial access bandwidth portion based on a second rule, the second terminal determining a second initial access bandwidth portion based on a remaining minimum system information (RMSI), the first rule and the second rule being partially different or completely different.

[0052] Optionally, the step of the first terminal determining a first initial access bandwidth portion based on a first rule includes determining the first initial access bandwidth portion based on second configuration information in the RMSI. portion determining whether the second configuration information is 1 indicating the initial access bandwidth portion of the terminal.

[0053] Optionally, the step of the first terminal determining a first initial access bandwidth portion based on a first rule includes, in response to the RMSI including second configuration information, determining the first initial access bandwidth portion based on second configuration information in the RMSI. portion determining whether the second configuration information is 1or, in response to the RMSI not including second configuration information, determining the first initial access bandwidth portion based on configuration information of control resource set 0.

[0054] Optionally, the step of the first terminal determining a first initial access bandwidth portion based on a first rule includes: During RMSI determining the second initial access bandwidth portion based on first configuration information; said first configuration information indicating an initial access bandwidth portion of said second terminal; and determining a bandwidth of a portion of the second initial access bandwidth as the first initial access bandwidth portion based on an access bandwidth capability of the first terminal.

[0055] Optionally, the step of the first terminal determining a first initial access bandwidth portion based on a first rule includes: During RMSI determining the second initial access bandwidth portion based on first configuration information; said first configuration information indicating an initial access bandwidth portion of said second terminal; and determining the first initial access bandwidth portion based on a magnitude relationship between the second initial access bandwidth portion and an access bandwidth capability of the first terminal.

[0056] Optionally, the step of the first terminal determining a first initial access bandwidth portion based on a first rule includes the steps of: determining the first initial access bandwidth portion based on configuration information of a control resource set 0 when the second initial access bandwidth portion exceeds an access bandwidth capability of the first terminal; and determining the first initial access bandwidth portion based on second configuration information in the RMSI, wherein the second configuration information is 1 and determining a portion of the bandwidth of the second initial access bandwidth as the first initial access bandwidth portion based on the access bandwidth capability of the first terminal.

[0057] Optionally, the step of the first terminal determining a first initial access bandwidth portion based on a first rule includes a step of setting the second initial access bandwidth portion as the first initial access bandwidth portion if the second initial access bandwidth portion does not exceed the access bandwidth capability of the first terminal.

[0058] Optionally, the step of determining the first initial access bandwidth portion based on the configuration information of the control resource set 0 includes a step of determining a frequency resource in which the control resource set 0 exists as the first initial access bandwidth portion, or a step of determining an end position of the first initial access bandwidth by setting the start frequency position of the frequency resource in which the control resource set 0 exists as the start position of the first initial access bandwidth portion and setting the access bandwidth capability of the first terminal as an offset of the start frequency position.

[0059] Optionally, the step of determining a portion of the bandwidth of the second initial access bandwidth as the first initial access bandwidth portion based on the access bandwidth capability of the first terminal includes a step of determining a start frequency position of the second initial access bandwidth portion as a start position of the first initial access bandwidth portion and an end position of the first initial access bandwidth as an offset of the start frequency position, the access bandwidth capability of the first terminal.

[0060] Incidentally, step 201 and the selectable steps may be arbitrarily combined.

[0061] 3 is a flowchart of an initial access bandwidth portion configuration method according to an exemplary embodiment. The method can be performed by the access network device. Referring to FIG. 3, the method includes the following step 301:

[0062] In step 301, a remaining minimum system information (RMSI) is generated, the RMSI including first configuration information indicating an initial access bandwidth portion of a second terminal and second configuration information indicating an initial access bandwidth portion of a first terminal, and the access bandwidth capability of the first terminal is smaller than the access bandwidth capability of the second terminal.

[0063] In step 302, the RMSI is transmitted.

[0064] Figure 4 is a flow chart of a method for determining an initial access bandwidth portion shown by an exemplary embodiment. The method can be jointly performed by the access network device and the terminal of Figure 1, and in the embodiment shown in Figure 4, the terminal includes a first terminal and a second terminal, and the access bandwidth capability of the first terminal is lower than that of the second terminal. Referring to Figure 4, the method includes the following steps 401-404:

[0065] In step 401, the access network device transmits configuration information and RMSI of CORESET#0.

[0066] The configuration information of CORESET#0 indicates frequency resources in which CORESET#0 exists. Exemplarily, the configuration information of CORESET#0 may include information such as a start frequency position and a frequency domain width.

[0067] The terminal can acquire a PDCCH for scheduling system messages (eg, SIB1, RMSI, etc.) based on the configuration information of CORESET#0.

[0068] After acquiring a PDCCH associated with the RMSI, the terminal acquires a Physical Downlink Shared Channel (PDSCH) corresponding to this PDCCH, and analyzes the RMSI from the PDSCH data.

[0069] In one possible embodiment, the RMSI includes first configuration information indicating an initial access bandwidth portion of the second terminal, while in another possible embodiment, the RMSI does not include the first configuration information.

[0070] In step 402, the first terminal determines a first initial access bandwidth portion based on the configuration information of CORESET#0.

[0071] In one possible embodiment, this step 402 includes determining the frequency resource in which CORESET#0 exists as the first initial access bandwidth portion, i.e., determining the frequency size and frequency bandwidth occupied by CORESET#0 as the first initial access bandwidth portion.

[0072] In another possible embodiment, this step 402 includes a step of determining the end position of the first initial access bandwidth portion by taking the start frequency position of the frequency resource in which CORESET#0 exists as the start position of the first initial access bandwidth portion and taking the access bandwidth capability of the first terminal as an offset of the start frequency position.

[0073] In step 403, the second terminal receives the configuration information and RMSI of CORESET#0.

[0074] In step 404, the second terminal determines a second initial access bandwidth portion based on the RMSI.

[0075] In this step 404, if the RMSI includes the first configuration information, the initial access bandwidth portion indicated by the first configuration information is set as the second initial access bandwidth portion. Or, if the RMSI does not include the first configuration information, the second initial access bandwidth portion is determined based on the configuration information of CORESET#0. That is, the frequency resource in which the control resource set 0 exists is determined as the second initial access bandwidth portion.

[0076] Illustratively, the method shown in Figure 4 can determine an initial downlink access bandwidth portion, that is, the first initial access bandwidth portion and the second initial access bandwidth portion are both initial downlink access bandwidth portions.

[0077] 4, the first rule is to only determine the first initial access bandwidth portion based on the configuration information of CORESET#0 (see step 402). The second rule is to determine the initial access bandwidth portion indicated by the first configuration information as the second initial access bandwidth portion if the RMSI includes the first configuration information, and to determine the second initial access bandwidth portion based on the configuration information of CORESET#0 if the RMSI does not include the first configuration information (see step 404), that is, the first rule and the second rule are not completely the same.

[0078] In an embodiment of the present disclosure, regardless of whether the RMSI includes first configuration information, and regardless of whether the initial access bandwidth portion indicated by the first configuration information exceeds the access bandwidth capability of the first terminal, the first terminal determines the first initial access bandwidth portion based on the configuration information of CORESET#0, and since the frequency resource in which CORESET#0 exists is small, the first initial bandwidth portion determined based on the configuration information of CORESET#0 does not exceed the access bandwidth capability of the first terminal, which is advantageous for normal operation of the first terminal.

[0079] Fig. 5 is a flow chart of a method for determining an initial access bandwidth portion according to an exemplary embodiment. The method can be jointly performed by the access network device and the terminal, and in the embodiment shown in Fig. 5, the terminal includes a first terminal and a second terminal, and the access bandwidth capability of the first terminal is lower than the access bandwidth capability of the second terminal. Referring to Fig. 5, the method includes the following steps S501-505:

[0080] In step 501, the access network device transmits the RMSI.

[0081] In one possible embodiment, the RMSI includes first configuration information indicating an initial access bandwidth portion of the second terminal and second configuration information indicating an initial access bandwidth portion of the first terminal, in another possible embodiment, the RMSI does not include the first configuration information and includes the second configuration information.

[0082] In order to ensure that the first initial access bandwidth portion determined by the first terminal does not exceed the access bandwidth capability of the first terminal, the initial access bandwidth portion indicated by the second configuration information does not exceed the access bandwidth capability of the first terminal.

[0083] Illustratively, when the RMSI simultaneously includes the first configuration information and the second configuration information, the initial access bandwidth portion indicated by the second configuration information is smaller than the initial access bandwidth portion indicated by the first configuration information.

[0084] In step 502, the first terminal receives the RMSI.

[0085] In step 503, the first terminal determines a first initial access bandwidth portion based on the second configuration information.

[0086] That is, the initial access bandwidth portion indicated by the second configuration information is set as the first initial access bandwidth portion.

[0087] In step 504, the second terminal receives the RMSI.

[0088] In step 505, the second terminal determines a second initial access bandwidth portion based on the RMSI.

[0089] The relevant content of step 505 can be referred to as step 404, and a detailed description thereof will be omitted here.

That is, the first rule and the second rule are completely different.

[0105] In the embodiment of the present disclosure, the second configuration information is set individually for the first terminal with low access bandwidth capability, and when the RMSI includes the second configuration information, the first initial access bandwidth portion determined by the first terminal based on the second configuration information does not exceed the access bandwidth capability of the first terminal; when the RMSI does not include the second configuration information, the first terminal determines the first initial access bandwidth portion based on the configuration information of CORESET#0, and because the frequency resource in which CORESET#0 exists is small, the first initial bandwidth portion determined based on the configuration information of CORESET#0 does not exceed the access bandwidth capability of the first terminal.

[0115] If the second initial access bandwidth portion is the initial downlink access bandwidth, this step 706 may refer to step 404 above.

[0116] If the second initial access bandwidth portion is an initial uplink access bandwidth portion, this step 706 may include a step of setting the initial access bandwidth portion indicated by the first configuration information in the RMSI as the second initial access bandwidth portion.

[0117] 7, the first rule is to determine the first initial access bandwidth portion based on the second configuration information (see steps 703 and 704), and the second rule refers to step 706. That is, the first rule and the second rule are completely different.

[0118] In an embodiment of the present disclosure, for a first terminal having a low access bandwidth capability, a portion of the second initial access bandwidth is determined as the first initial access bandwidth portion based on the access bandwidth capability of the first terminal, so that when the second initial access bandwidth is larger than the access bandwidth capability of the first terminal, the first initial access bandwidth portion determined by the first terminal does not exceed the access bandwidth capability of the first terminal, which is beneficial for the normal operation of the first terminal.

[0119] Figure 8 is a flow chart of a method for determining an initial access bandwidth portion according to an exemplary embodiment. The method can be jointly performed by the access network device and the terminal. In the embodiment shown in Figure 8, the terminal includes a first terminal and a second terminal, and the access bandwidth capability of the first terminal is lower than that of the second terminal. Referring to Figure 8, the method includes the following steps 801-806:

[0120] In step 801, the access network device transmits configuration information and RMSI of CORESET#0.

[0121] In step 802, the first terminal receives the RMSI.

[0122] In step 803, the first terminal determines a second initial access bandwidth portion based on the first configuration information.

[0123] In step 804, the first terminal compares the second initial access bandwidth portion with the access bandwidth capability of the first terminal.

[0124] If the second initial access bandwidth portion exceeds the access bandwidth capability of the first terminal, execute step 805; if the second initial access bandwidth portion does not exceed the access bandwidth capability of the first terminal, execute step 806.

[0127] In some embodiments of the present disclosure, step 805 may be substituted for step 503, or step 603, or steps 703 and 704.

[0128] Note that when this step 805 is replaced by step 503 or replaced by steps 703 and 704, the first initial access bandwidth portion may be an initial uplink access bandwidth portion or an initial downlink access bandwidth portion, and when this step 805 is replaced by step 603, the first initial access bandwidth portion is an initial downlink access bandwidth portion.

[0129] In step 806, the first terminal determines the second initial access bandwidth portion as the first initial access bandwidth portion.

[0130] Through steps 803 to 806, it is possible to realize the determination of the first initial access bandwidth portion based on the magnitude relationship between the second initial access bandwidth portion and the access bandwidth capability of the first terminal.

[0131] In this embodiment, the manner in which the second terminal determines the second initial access bandwidth portion may refer to step 404, and the description thereof will be omitted here.

[0132] 8, the first rule refers to steps 803 to 806, and the second rule refers to step 404. That is, the first rule and the second rule are completely different.

[0133] Next, the determination of the initial downlink bandwidth portion (initial DL BWP) and the initial uplink bandwidth portion (initial UL BWP) will be described, respectively.

[0134] 1. Determination of initial DL BWP If the initial DL BWP configured by the RMSI is less than or equal to the access bandwidth capability of the first terminal, the first terminal sets the initial DL BWP according to the configuration in the RMSI. If the initial DL BWP configured by the RMSI is greater than the access bandwidth capability of the first terminal, the initial DL BWP is determined using one of the following three methods:

[0135] In the first type, the first terminal determines the initial DL BWP based on predefined rule 1 or 2. Predefined rule 1: The frequency size and frequency bandwidth occupied by CORESET#0 are set as the user's initial DL BWP. Predefined rule 2: Starting from the starting frequency position of CORESET#0, the end point of the initial DL BWP is determined based on the bandwidth capability of the first terminal.

[0136] In the second type, the access network device additionally configures one Initial DL BWP_extra (i.e., second configuration information) for the first terminal (also called NR-lite) in the RMSI, and the first terminal takes this initial DL BWP_extra as the initial DL BWP.

[0137] The third type is a combination of the first and second types. The access network device can additionally configure the Initial DL BWP_extra in the RMSI, but the access network device does not need to configure the Initial DL BWP_extra. When the access network device does not configure the Initial DL BWP_extra, it determines the initial DL BWP in the first type of manner, and when the access network device configures the Initial DL BWP_extra, it determines the initial DL BWP in the second type of manner.

[0138] II. Determination of initial UL BWP If the initial UL BWP configured by the RMSI is less than or equal to the access bandwidth capability of the first terminal, the first terminal sets the initial UL BWP according to the configuration in the RMSI. If the initial UL BWP configured by the RMSI is greater than the access bandwidth capability of the first terminal, the initial UL BWP is determined by one of the following three methods.

[0139] The first type determines the initial UL BWP based on predefined rules. Predefined rule: The starting frequency position of the initial UL BWP configured by the RMSI is the starting point, and the end point of the initial UL BWP is determined based on the access bandwidth capability of the first terminal.

[0140] In the second type, the access network device additionally configures an Initial UL BWP_extra (i.e., second configuration information) in the RMSI for the first terminal (also called NR-lite), and the first terminal sets this initial UL BWP_extra as the initial UL BWP.

[0141] The third type is a combination of the first and second types. The access network device can additionally configure Initial UL BWP_extra in the RMSI, but the access network device does not need to configure Initial UL BWP_extra. If the access network device does not configure Initial UL BWP_extra, it determines the initial UL BWP according to the first type of method, and if the access network device configures Initial UL BWP_extra, it determines the initial UL BWP according to the second type of method.

[0142] In an embodiment of the present disclosure, for a first terminal having a low access bandwidth capability, if the initial access bandwidth portion indicated by the first configuration information (i.e., the second initial access bandwidth portion) exceeds the initial access bandwidth capability of the first terminal, the first initial access bandwidth portion is determined based on the configuration information of CORESET#0, or the first initial access bandwidth portion is determined based on the second configuration information, and a portion of the bandwidth of the second initial access bandwidth is determined as the first initial access bandwidth portion based on the access bandwidth capability of the first terminal. Therefore, when the second initial access bandwidth is larger than the access bandwidth capability of the first terminal, the first initial access bandwidth portion determined by the first terminal always does not exceed the access bandwidth capability of the first terminal, which is beneficial for normal operation of the first terminal.
