Description

[0001] This application is a divisional application of a Chinese application with an application number of 202080001002.6, an application date of May 15, 2020, and an invention title of "Method, Apparatus, and Storage Medium for Determining and Configuring Initial Access Bandwidth Portion". Technical Field

[0002] The present disclosure relates to the field of communication technologies, and in particular, to a method, apparatus, and storage medium for determining and configuring an initial access bandwidth portion. Background Art

[0003] The initial access bandwidth portion, also known as the Initial Bandwidth Part, is mainly used for the initial access process of a terminal.

[0004] In related technologies, an access network device may carry configuration information for configuring the initial access bandwidth portion through Remaining minimumsysteminformation (RMSI). If the configuration information is included in the RMSI, the terminal will determine the initial access bandwidth portion according to the configuration information; if the configuration information is not included in the RMSI, the terminal will determine the initial access bandwidth portion according to the resources where the Control Resource Set 0 (CORESET#0) is located.

[0005] However, when there are some terminals with poor capabilities in the same communication system, the initial access bandwidth portion configured by the access network device in the RMSI may exceed the capabilities of these terminals with poor capabilities, resulting in the inability of these terminals with poor capabilities to work properly.

[0082] Please refer to Figure 1 , which shows a schematic structural diagram of a mobile communication system provided by an embodiment of the present application. The mobile communication system may include: an access network device 10 and a terminal 20.

[0083] The access network device 10 is deployed in a radio access network to provide a wireless access function for the terminal 20. The access network device may be a base station (BS). The access network device 10 may communicate wirelessly with the terminal 20 via one or more antennas. The access network device 10 may provide communication coverage for its geographical area. The base station may include different types such as macro base stations, micro base stations, relay stations, access points, etc. In some embodiments, the base station may be referred to by those skilled in the art as a base station transceiver, radio base station, access point, radio transceiver, basic service set (BSS), extended service set (ESS), Node B, evolved Node B (eNB or eNodeB), or some other suitable terms. Exemplarily, in a 5G system, the base station is referred to as a gNB. For ease of description, in the embodiments of the present application, the device that provides the wireless communication function for the terminal 20 is collectively referred to as an access network device.

[0084] The terminals 20 may be scattered throughout the mobile communication system, and each terminal 20 may be stationary or mobile. The terminal 20 may also be referred to by those skilled in the art as a mobile station, user station, mobile unit, user unit, radio unit, remote unit, mobile device, user equipment, radio equipment, radio communication equipment, remote device, mobile user station, access terminal, mobile terminal, radio terminal, remote terminal, handheld device, user agent, mobile client, client, or some other suitable terms. The terminal 20 may be a cellular phone, personal digital assistant (PDA), wireless modem, radio communication equipment, handheld device, tablet computer, laptop computer, cordless phone, wireless local loop (WLL) station, etc. The terminal 20 is capable of communicating with the access network device 10 in the mobile communication system.

[0085] The access network device 10 and the terminal 20 may communicate with each other through air interface technology, for example, through cellular technology. The communication link between the access network device 10 and the terminal 20 may include: downlink (DL) transmission from the access network device 10 to the terminal 20, and / or uplink (UP) transmission from the terminal 20 to the access network device 10. The downlink transmission may also be referred to as forward link transmission, and the uplink transmission may also be referred to as reverse link transmission. In some examples, the downlink transmission may include the transmission of discovery signals, which may include reference signals and / or synchronization signals.

[0086] The above Figure 1The mobile communication system shown may be a Long Term Evolution (LTE) system, or a next-generation evolution system based on the LTE system, such as an LTE-A (LTE-Advanced) system or a 5th Generation (5G) system (also known as an NR system), or a next-generation evolution system based on the 5G system, and so on. In the embodiments of the present application, the terms "system" and "network" are often used interchangeably, but those skilled in the art can understand their meanings.

[0087] The communication systems and service scenarios described in the embodiments of the present disclosure are for more clearly illustrating the technical solutions of the embodiments of the present disclosure, and do not constitute a limitation on the technical solutions provided by the embodiments of the present disclosure. Those of ordinary skill in the art know that with the evolution of communication systems and the emergence of new service scenarios, the technical solutions provided by the embodiments of the present disclosure are equally applicable to similar technical problems.

[0088] In Figure 1 In the communication system shown, the terminal needs to use a synchronization signal block (i.e., a synchronization signal and a physical broadcast channel resource block (Synchronization Signal and PBCH Block, SSB)) to complete initial access.

[0089] In the time domain, one SSB occupies 4 symbols (i.e., Orthogonal Frequency Division Multiplexing (OFDM) symbols), including: 1 symbol of the Primary Synchronized Signal (PSS), 1 symbol of the Secondary Synchronized Signal (SSS), and 2 symbols of the Physical Broadcast Channel (PBCH). Within the SSB, the symbols are numbered from 0 to 3 in ascending order. In the frequency domain, one SSB occupies 24 consecutive resource blocks (Resource Block, RB). Each RB includes 12 subcarriers. The subcarriers in the above 24 RBs are numbered from 0 to 287 in ascending order, starting from the RB with the lowest number. For the PSS and SSS, the resources are mapped to the 127th subcarrier in the middle; for the PBCH, the resources are mapped to the 288th subcarrier. The PSS, SSS, and PBCH have the same Cyclic Prefix (CP) length and subcarrier spacing. The subcarrier spacing can be configured as 15 kHz, 30 kHz, 120 kHz, and 240 kHz.

[0090] During the initial access process, the terminal first detects the received synchronization signal block, obtains the Master Information Block (MIB) in the SSB, and obtains from the MIB the control resource set 0 (CORESET#0) of the physical downlink control channel (PDCCH) for the terminal to monitor and schedule other system messages (such as System Information Block 1 (SIB1), RMSI) and the configuration information of the search space (SS). According to the indication 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 resources occupied by CORESET#0, that is, the number of RBs.

[0091] To meet the requirements of different communication services, Figure 1 There are two types of terminals in the communication system shown, namely the first terminal and the second terminal. The capabilities of the two types of terminals can be different. Exemplarily, the bandwidth of the initial access bandwidth part supported by the second terminal is greater than that supported by the first terminal, that is, the access bandwidth capability of the second terminal exceeds that of the first terminal.

[0092] In the embodiments of the present disclosure, the first terminal can also be referred to as a reduced-capability New Radio device, a reduced-capability User Equipment, a Capability-restricted UE, or an NR-lite device. Exemplarily, the first terminal can be some sensors in the industrial Internet of Things, wireless video monitoring devices in smart cities, and wearable devices such as bracelets, watches, and health care monitoring devices. The second device can also be referred to as a normal device, such as a mobile terminal.

[0093] Figure 2 is a flowchart of a method for determining an initial access bandwidth part according to an exemplary embodiment. This method can be executed by the aforementioned first terminal. Refer to Figure 2 and the method includes the following steps:

[0094] In step 201, the first terminal determines a first initial access bandwidth portion based on a first rule, where the first initial access bandwidth portion does not exceed the access bandwidth capability of the first terminal, and the access bandwidth capability of the first terminal is lower than that of the second terminal. The second terminal is a terminal that determines a second initial access bandwidth portion based on the Remaining Master System Information (RMSI) according to a second rule. Here, the first rule and the second rule are not completely the same or are completely different.

[0095] Optionally, the first terminal determines the first initial access bandwidth portion based on the first rule, including:

[0096] Determining the first initial access bandwidth portion according to the configuration information of control resource set 0.

[0097] Optionally, the first terminal determines the first initial access bandwidth portion based on the first rule, including:

[0100] In response to the RMSI including the second configuration information, determining the first initial access bandwidth according to the second configuration information in the RMSI, where the second configuration information is used to indicate the initial access bandwidth portion of the second terminal;

[0101] Or,

[0102] In response to the RMSI not including the second configuration information, determining the first initial access bandwidth portion according to the configuration information of control resource set 0.

[0104] Determining the second initial access bandwidth portion according to the first configuration information;

[0105] Determining the partial bandwidth of the second initial access bandwidth as the first initial access bandwidth portion according to the access bandwidth capability of the first terminal.

[0106] Optionally, the first terminal determines the first initial access bandwidth portion based on the first rule, including:

[0107] Determining the second initial access bandwidth portion according to the first configuration information;

[0108] Determine the first initial access bandwidth portion according to the magnitude relationship between the second initial access bandwidth portion and the access bandwidth capability of the first terminal.

[0109] Optionally, the first terminal determines the first initial access bandwidth portion based on a first rule, including:

[0110] If the second initial access bandwidth portion exceeds the access bandwidth capability of the first terminal, then perform any one of the following steps:

[0111] Determine the first initial access bandwidth portion according to the configuration information of control resource set 0;

[0112] Determine the first initial access bandwidth portion according to the second configuration information in the RMSI, where the second configuration information is used to indicate the initial access bandwidth portion of the second terminal; or,

[0113] Determine that the partial bandwidth of the second initial access bandwidth is the first initial access bandwidth portion according to the access bandwidth capability of the first terminal.

[0114] Optionally, the first terminal determines the first initial access bandwidth portion based on a first rule, including:

[0115] If the second initial access bandwidth portion does not exceed the access bandwidth capability of the first terminal, then use the second initial access bandwidth portion as the first initial access bandwidth portion.

[0116] Optionally, the determination of the first initial access bandwidth portion according to the configuration information of control resource set 0 includes:

[0117] Determine the frequency resource where control resource set 0 is located as the first initial access bandwidth portion; or,

[0118] Use the starting frequency position of the frequency resource where control resource set 0 is located as the starting position of the first initial access bandwidth portion, and use the access bandwidth capability of the first terminal as the offset of the starting frequency position to determine the ending position of the first initial access bandwidth.

[0119] Optionally, the determination that the partial bandwidth of the second initial access bandwidth is the first initial access bandwidth portion according to the access bandwidth capability of the first terminal includes:

[0120] Use the starting frequency position of the second initial access bandwidth portion as the starting position of the first initial access bandwidth portion, and use the access bandwidth capability of the first terminal as the offset of the starting frequency position to determine the ending position of the first initial access bandwidth.

[0121] It should be noted that the foregoing step 201 and the above optional steps can be combined arbitrarily.

[0122] Figure 3 is a flowchart of a method for configuring an initial access bandwidth part shown according to an exemplary embodiment. This method can be executed by the foregoing access network device, see Figure 3 , and this method includes the following steps:

[0123] In step 301, generate the Remaining Master System Information (RMSI), where the RMSI includes first configuration information for indicating the initial access bandwidth part of the second terminal and second configuration information for indicating the initial access bandwidth part of the first terminal, and the access bandwidth capability of the first terminal is less than that of the second terminal;

[0124] In step 302, send the RMSI.

[0125] Figure 4 is a flowchart of a method for determining an initial access bandwidth part shown according to an exemplary embodiment. This method can be jointly executed by the access network device and the terminal in Figure 1 . 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, see Figure 4 , and this method includes the following steps:

[0126] In step 401, the access network device sends the configuration information of CORESET#0 and the RMSI.

[0127] The configuration information of CORESET#0 is used to indicate the frequency resources where CORESET#0 is located. Exemplarily, the configuration information of CORESET#0 may include information such as the starting frequency position and the width of the frequency domain.

[0128] The terminal can obtain the PDCCH for scheduling system messages (such as SIB1, RMSI, etc.) according to the configuration information of CORESET#0.

[0129] After the terminal obtains the PDCCH associated with the RMSI, it then obtains the Physical Downlink Shared Channel (PDSCH) corresponding to the PDCCH, and parses the RMSI from the PDSCH data.

[0130] In a possible implementation manner, the RMSI includes first configuration information for indicating the initial access bandwidth part of the second terminal. In another possible implementation manner, the RMSI does not include the first configuration information.

[0131] In step 402, the first terminal determines a first initial access bandwidth portion according to the configuration information of CORESET #0.

[0132] In a possible implementation, step 402 includes: determining the frequency resource where CORESET #0 is located as the first initial access bandwidth portion. That is, determining the frequency size and frequency bandwidth occupied by CORESET #0 as the first initial access bandwidth portion.

[0133] In another possible implementation, step 402 includes: using the starting frequency position of the frequency resource where CORESET #0 is located as the starting position of the first initial access bandwidth portion, and using the access bandwidth capability of the first terminal as the offset of the starting frequency position to determine the ending position of the first initial access bandwidth.

[0134] In step 403, the second terminal receives the configuration information of CORESET #0 and the RMSI.

[0135] In step 404, the second terminal determines a second initial access bandwidth portion according to the RMSI.

[0136] In this step 404, if the RMSI includes first configuration information, then use the initial access bandwidth portion indicated by the first configuration information as the second initial access bandwidth portion. Or, if the RMSI does not include the first configuration information, then determine the second initial access bandwidth portion according to the configuration information of CORESET #0. That is, determine the frequency resource where the control resource set 0 is located as the second initial access bandwidth portion.

[0137] Exemplarily, Figure 4 The method shown can be used to determine the initial downlink access bandwidth portion. That is, both the first initial access bandwidth portion and the second initial access bandwidth portion are the initial downlink access bandwidth portions.

[0138] It should be noted that in Figure 4 the method shown, the first rule is to determine the first initial access bandwidth portion only according to the configuration information of CORESET #0 (see step 402). The second rule is: if the RMSI includes the first configuration information, then use the initial access bandwidth portion indicated by the first configuration information as the second initial access bandwidth portion; if the RMSI does not include the first configuration information, then determine the second initial access bandwidth portion according to the configuration information of CORESET #0 (see step 404). That is, the first rule and the second rule are not exactly the same.

[0139] In the embodiments of the present disclosure, regardless of whether the RMSI contains the 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 according to the configuration information of CORESET#0. Since the frequency resources where CORESET#0 is located are small, the first initial bandwidth portion determined according to the configuration information of CORESET#0 will not exceed the access bandwidth capability of the first terminal, which is beneficial to the normal operation of the first terminal.

[0140] Figure 5 is a flowchart of a method for determining an initial access bandwidth portion shown according to an exemplary embodiment. This method can be jointly executed by the aforementioned access network device and the terminal. In Figure 5 the illustrated embodiment, 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. Refer to Figure 5 and the method includes the following steps:

[0141] In step 501, the access network device sends the RMSI.

[0142] In a possible implementation, the RMSI includes the first configuration information for indicating the initial access bandwidth portion of the second terminal and the second configuration information for indicating the initial access bandwidth portion of the first terminal. In another possible implementation, the RMSI includes the second configuration information and does not include the first configuration information.

[0143] 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.

[0144] Exemplarily, when the RMSI includes both the first configuration information and the second configuration information, the initial access bandwidth portion indicated by the second configuration information is less than the initial access bandwidth portion indicated by the first configuration information.

[0145] In step 502, the first terminal receives the RMSI.

[0146] In step 503, the first terminal determines the first initial access bandwidth portion according to the second configuration information.

[0147] That is, the initial access bandwidth portion indicated by the second configuration information is used as the first initial access bandwidth portion.

[0148] In step 504, the second terminal receives the RMSI.

[0149] In step 505, the second terminal determines a second initial access bandwidth part according to the RMSI.

[0150] For the relevant content of this step 505, reference can be made to the foregoing step 404, and detailed description is omitted here.

[0151] Exemplarily, Figure 5 The method shown can be used to determine an initial downlink access bandwidth part, or an initial uplink access bandwidth part. That is, both the first initial access bandwidth part and the second initial access bandwidth part are the initial downlink access bandwidth part, or both are the initial uplink access bandwidth part.

[0152] It should be noted that, in Figure 5 the method shown, the first rule is: determine the first initial access bandwidth part according to the second configuration information (see step 503). The second rule is: if the RMSI includes the first configuration information, then use the initial access bandwidth part indicated by the first configuration information as the second initial access bandwidth part; if the RMSI does not include the first configuration information, then determine the second initial access bandwidth part according to the configuration information of CORESET#0 (see step 404). That is, the first rule and the second rule are completely different.

[0153] In the embodiments of the present disclosure, for the first terminal with poor access bandwidth capability, the second configuration information is separately set to ensure that the first initial access bandwidth part determined by the first terminal according to the second configuration information does not exceed the access bandwidth capability of the first terminal, which is beneficial to the normal operation of the first terminal.

[0154] Figure 6 is a flowchart of a method for determining an initial access bandwidth part shown according to an exemplary embodiment. This method can be jointly executed by the foregoing access network device and the terminal. In Figure 6 the embodiments shown, 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. See Figure 6 , and the method includes the following steps:

[0155] In step 601, the access network device sends the configuration information of CORESET#0 and the RMSI.

[0156] In a possible implementation, the RMSI includes at least one of first configuration information for indicating an initial access bandwidth portion of a second terminal and second configuration information for indicating an initial access bandwidth portion of a first terminal. In another possible implementation, the RMSI includes neither the first configuration information nor the second configuration information. That is to say, the access network device may configure the first configuration information in the RMSI or may not configure the first configuration information; similarly, the access network device may configure the second configuration information in the RMSI or may not configure the second configuration information.

[0157] In step 602, the first terminal receives the RMSI.

[0158] In step 603, the first terminal determines a first initial access bandwidth portion according to the RMSI.

[0159] This step 603 may include: if the second configuration information in the RMSI is not missing (i.e., the RMSI includes the second configuration information), then determine the first initial access bandwidth according to the second configuration information in the RMSI; or, if the second configuration information in the RMSI is missing (i.e., the RMSI does not include the second configuration information), then determine the first initial access bandwidth portion according to the configuration information of CORESET #0.

[0160] Here, the manner of determining the first initial access bandwidth according to the second configuration information in the RMSI may refer to step 503; the manner of determining the first initial access bandwidth portion according to the configuration information of CORESET #0 may refer to step 402, and the detailed description is omitted here.

[0161] In step 604, the second terminal receives the RMSI.

[0162] In step 605, the second terminal determines a second initial access bandwidth portion according to the RMSI.

[0163] The relevant content of this step 605 may refer to the foregoing step 404, and the detailed description is omitted here.

[0164] Optionally, Figure 6 The method shown can be used to determine an initial downlink access bandwidth portion. That is, both the first initial access bandwidth portion and the second initial access bandwidth portion are initial downlink access bandwidth portions.

[0165] It should be noted that in Figure 6In the method shown, the first rule is: determine a first initial access bandwidth portion according to second configuration information (see step 603). The second rule is: if the first configuration information is included in the RMSI, use the initial access bandwidth portion indicated by the first configuration information as the second initial access bandwidth portion; if the first configuration information is not included in the RMSI, determine the second initial access bandwidth portion according to the configuration information of CORESET#0. That is, the first rule and the second rule are completely different.

[0166] In the embodiments of the present disclosure, for a first terminal with poor access bandwidth capability, second configuration information is set separately. When the second configuration information is included in the RMSI, the first initial access bandwidth portion determined by the first terminal according to the second configuration information does not exceed the access bandwidth capability of the first terminal. When the second configuration information is not included in the RMSI, the first terminal determines the first initial access bandwidth portion according to the configuration information of CORESET#0. Since the frequency resources where CORESET#0 is located are small, the first initial bandwidth portion determined according to the configuration information of CORESET#0 will not exceed the access bandwidth capability of the first terminal. Therefore, it can be ensured that 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 to the normal operation of the first terminal.

[0167] Figure 7 is a flowchart of a method for determining an initial access bandwidth portion shown according to an exemplary embodiment. This method can be jointly executed by the aforementioned access network device and the terminal. In Figure 7 the embodiment shown, 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. See Figure 7 , this method includes the following steps:

[0168] In step 701, the access network device sends the configuration information of CORESET#0 and the RMSI.

[0169] In step 702, the first terminal receives the RMSI.

[0170] In step 703, the first terminal determines a second initial access bandwidth portion according to the first configuration information;

[0171] In step 704, the first terminal determines, according to the access bandwidth capability of the first terminal, that a partial bandwidth of the second initial access bandwidth is the first initial access bandwidth portion.

[0172] Exemplarily, step 704 may include: The first terminal uses the starting frequency position of the second initial access bandwidth portion as the starting position of the first initial access bandwidth portion, and uses the access bandwidth capability of the first terminal as the offset of the starting frequency position to determine the ending position of the first initial access bandwidth.

[0173] In step 705, the second terminal receives the RMSI.

[0174] In step 706, the second terminal determines the second initial access bandwidth portion according to the RMSI.

[0175] Optionally, Figure 7 The method shown can be used to determine the initial downlink access bandwidth portion, or the initial uplink access bandwidth portion. That is, both the first initial access bandwidth portion and the second initial access bandwidth portion are the initial downlink access bandwidth portion, or both are the initial uplink access bandwidth portion.

[0176] When the second initial access bandwidth portion is the initial downlink access bandwidth, step 706 can refer to the aforementioned step 404.

[0177] When the second initial access bandwidth portion is the initial uplink access bandwidth portion, step 706 may include: using the initial access bandwidth portion indicated by the first configuration information in the RMSI as the second initial access bandwidth portion.

[0178] It should be noted that in Figure 7 the method shown, the first rule is: determining the first initial access bandwidth portion according to the second configuration information (see steps 703 and 704). The second rule refers to step 706, that is, the first rule and the second rule are completely different.

[0179] In the embodiments of the present disclosure, for the first terminal with poor access bandwidth capability, by determining the partial bandwidth of the second initial access bandwidth as the first initial access bandwidth portion according to the access bandwidth capability of the first terminal, when the second initial access bandwidth is greater than the access bandwidth capability of the first terminal, the first initial access bandwidth portion determined by the first terminal will not exceed the access bandwidth capability of the first terminal, which is beneficial to the normal operation of the first terminal.

[0180] Figure 8 is a flowchart of a method for determining an initial access bandwidth portion shown according to an exemplary embodiment. This method can be jointly executed by the aforementioned access network device and the terminal. In Figure 8 the embodiments shown, 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. See Figure 8 , this method includes the following steps:

[0181] In step 801, the access network device sends the configuration information of CORESET #0 and the RMSI.

[0182] In step 802, the first terminal receives the RMSI.

[0183] In step 803, the first terminal determines a second initial access bandwidth part according to the first configuration information.

[0184] In step 804, the first terminal compares the second initial access bandwidth part with the access bandwidth capability of the first terminal.

[0185] If the second initial access bandwidth part exceeds the access bandwidth capability of the first terminal, step 805 is executed; if the second initial access bandwidth part does not exceed the access bandwidth capability of the first terminal, step 806 is executed.

[0186] In step 805, the first terminal determines the first initial access bandwidth part according to the configuration information of CORESET #0.

[0187] For the relevant content of this step 805, reference can be made to the foregoing step 402.

[0188] In some embodiments of the present disclosure, this step 805 may be replaced by the foregoing step 503, or, the foregoing step 603, or, the foregoing steps 703 and 704.

[0189] It should be noted that when this step 805 is replaced by the foregoing step 503 or replaced by steps 703 and 704, the first initial access bandwidth part may be an initial uplink access bandwidth part or an initial downlink access bandwidth part; when this step 805 is replaced by the foregoing step 603, the first initial access bandwidth part is an initial downlink access bandwidth part.

[0190] In step 806, the first terminal uses the second initial access bandwidth part as the first initial access bandwidth part.

[0191] Through steps 803 to 806, it is possible to determine the first initial access bandwidth part according to the magnitude relationship between the second initial access bandwidth part and the access bandwidth capability of the first terminal.

[0192] In this embodiment, for the manner in which the second terminal determines the second initial access bandwidth part, reference can be made to the foregoing step 404, which will not be elaborated here.

[0193] It should be noted that in Figure 8 the method shown, 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.

[0194] The determination of the initial downlink bandwidth part (initial DL BWP) and the initial uplink bandwidth part (initial UL BWP) will be exemplarily described below, respectively.

[0195] I. Determination of initial DL BWP

[0196] When the initial DL BWP configured by RMSI is not greater than the access bandwidth capability of the first terminal, the first terminal sets the initial DL BWP according to the configuration in RMSI;

[0197] When the initial DL BWP configured by RMSI is greater than the access bandwidth capability of the first terminal, any one of the following 3 methods is used to determine the initial DL BWP:

[0198] The first method: The first terminal determines the initial DL BWP according to predefined rule 1 or 2

[0199] Predefined rule 1: Set the frequency size and frequency bandwidth occupied by CORESET#0 as the user's initial DL BWP;

[0200] Predefined rule 2: Starting from the starting frequency position of CORESET#0, determine the end point of the initial DL BWP according to the bandwidth capability of the first terminal.

[0201] The second method: The access network device additionally configures an Initial DL BWP_extra (i.e., the second configuration information) for the first terminal (which can also be called NR-lite) in RMSI, and the first terminal uses this initial DL BWP_extra as the initial DL BWP.

[0202] The third method: A combination of the first and second methods. The access network device can additionally configure Initial DL BWP_extra in RMSI, but the access network device can also not configure Initial DL BWP_extra. When the access network device does not configure Initial DL BWP_extra, the first method is used to determine the initial DL BWP. When the access network device configures Initial DL BWP_extra, the second method is used to determine the initial DL BWP.

[0203] II. Determination of initial UL BWP

[0204] When the initial UL BWP configured by RMSI is not greater than the access bandwidth capability of the first terminal, the first terminal sets the initial UL BWP according to the configuration in RMSI. When the initial UL BWP configured by RMSI is greater than the access bandwidth capability of the first terminal, any one of the following 3 methods is used to determine the initial UL BWP:

[0205] First, determine the initial UL BWP according to a predefined rule

[0206] Predefined rule: Starting from the starting frequency position of the initial UL BWP configured by RMSI, determine the end point of the initial UL BWP according to the access bandwidth capability of the first terminal

[0207] Second, the access network device additionally configures an Initial UL BWP_extra (i.e., the second configuration information) for the first terminal (which can also be referred to as NR-lite) in RMSI, and the first terminal uses this initial UL BWP_extra as the initial UL BWP.

[0208] Third, a combination of the first and the second. The access network device can additionally configure the Initial ULBWP_extra in RMSI, but the access network device can also not configure the Initial UL BWP_extra. When the access network device does not configure the Initial UL BWP_extra, the first method is used to determine the initial UL BWP; when the access network device configures the Initial UL BWP_extra, the second method is used to determine the initial UL BWP.

[0209] In the embodiments of the present disclosure, for the first terminal with poor access bandwidth capability, when the initial access bandwidth part (i.e., the second initial access bandwidth part) indicated by the first configuration information exceeds the initial access bandwidth capability of the first terminal, determine the first initial access bandwidth part according to the configuration information of CORESET#0, or determine the first initial access bandwidth part through the second configuration information, and determine the partial bandwidth of the second initial access bandwidth as the first initial access bandwidth part according to the access bandwidth capability of the first terminal, so that in the case where the second initial access bandwidth is greater than the access bandwidth capability of the first terminal, the first initial access bandwidth part determined by the first terminal will never exceed the access bandwidth capability of the first terminal, which is beneficial to the normal operation of the first terminal.
