Description

Technical Field

[0001] The present disclosure relates to the field of communication technology, and in particular to a method, device and storage medium for determining and configuring an initial access bandwidth portion. Background Art

[0002] The initial access bandwidth part, also called the initial bandwidth part (Initial Bandwidth Part), is mainly used for the initial access process of the terminal.

[0003] In the related art, the access network device can carry the configuration information for configuring the initial access bandwidth part through the remaining minimum system information (RMSI). If the RMSI contains the configuration information, the terminal will determine the initial access bandwidth part according to the configuration information; if the RMSI does not contain the configuration information, the terminal will determine the initial access bandwidth part according to the resources where the control resource set 0 (COntrol REsource SET0, CORESET#0) is located.

Exemplarily, in a 5G system, a base station is referred to as a gNB. For the convenience of description, in the embodiments of the present application, the above-mentioned devices that provide wireless communication functions for the terminal 20 are collectively referred to as access network devices.

[0083] The terminals 20 may be distributed throughout the mobile communication system, and each terminal 20 may be stationary or mobile. The terminals 20 may also be referred to 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 some other appropriate terms by those skilled in the art.

[0084] The access network device 10 and the terminal 20 can 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. Downlink transmission may also be referred to as forward link transmission, and uplink transmission may also be referred to as reverse link transmission. In some examples, downlink transmission may include transmission of a discovery signal, which may include a reference signal and / or a synchronization signal.

[0085] Above Figure 1 The 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 fifth generation (5th Generation, 5G) system (also known as an NR system), or a next generation evolution system based on the 5G system, etc. 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.

[0086] The communication system and business scenarios described in the embodiments of the present disclosure are intended to more clearly illustrate 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 skilled in the art will appreciate 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 are equally applicable to similar technical problems.

[0087] exist Figure 1In the communication system shown, the terminal needs to use the synchronization signal block (ie, the synchronization signal and physical broadcast channel resource block (Synchronization Signal and PBCH Block, SSB) to complete the initial access.

[0088] In the time domain, one SSB occupies 4 symbols (that is, Orthogonal Frequency Division Multiplexing (OFDM) symbols), including: 1 symbol of Primary Synchronized Signal (PSS), 1 symbol of Secondary Synchronized Signal (SSS) and 2 symbols of Physical Broadcast Channel (PBCH). Within the SSB, symbols are numbered from 0 to 3 in ascending order. In the frequency domain, one SSB occupies 24 consecutive resource blocks (RBs). Each RB includes 12 subcarriers, and the subcarriers in the above 24 RBs are numbered from 0 to 287 in ascending order, starting with the RB with the lowest number. For PSS and SSS, resources are mapped to the middle 127th subcarrier; for PBCH, resources are mapped to the 288th subcarrier. PSS, SSS, and PBCH have the same cyclic prefix (CP) length and subcarrier spacing. The subcarrier spacing is configurable to 15kHz, 30kHz, 120kHz and 240kHz.

[0089] During the initial access process, the terminal will first detect and receive the synchronization signal block, obtain the Master Information Block (MIB) in the SSB, and obtain the control resource set 0 (COntrol REsource SET0, CORESET#0) and search space (Search Space, SS) configuration information of the physical downlink control channel (PDCCH) of the terminal monitoring and scheduling other system messages (such as 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 resources occupied by CORESET#0, that is, the number of RBs.

[0090] In order to meet the needs of different communication services, Figure 1There are two terminals in the communication system shown, namely, a first terminal and a second terminal. The capabilities of the two terminals may be different. For example, the bandwidth of the initial access bandwidth part supported by the second terminal is greater than the bandwidth of the initial access bandwidth part supported by the first terminal, that is, the access bandwidth capability of the second terminal exceeds the access bandwidth capability of the first terminal.

[0091] In the embodiments of the present disclosure, the first terminal may also be referred to as a reduced capability NR device, a reduced capability UE, a capability restricted UE, or a simplified NR device (NR-lite). Exemplarily, the first terminal may be some sensors in the industrial Internet of Things, wireless video surveillance equipment in a smart city, and wearable devices such as bracelets, watches, and health and medical monitoring equipment. The second device may also be referred to as a normal device, such as a mobile terminal.

[0093] In step 201, the first terminal determines a first initial access bandwidth part based on a first rule, the first initial access bandwidth part does not exceed the access bandwidth capability of the first terminal, the access bandwidth capability of the first terminal is lower than the access bandwidth capability of the second terminal, the second terminal is a terminal that determines the second initial access bandwidth part based on a second rule according to the remaining main system information RMSI, wherein the first rule and the second rule are not completely the same or completely different.

[0109] If the second initial access bandwidth portion exceeds the access bandwidth capability of the first terminal, performing any one of the following steps:

[0110] Determining the first initial access bandwidth part according to the configuration information of the control resource set 0;

[0111] determining the first initial access bandwidth part according to second configuration information in the RMSI, where the second configuration information is used to indicate the initial access bandwidth part of the second terminal; or,

[0113] Optionally, the first terminal determines the first initial access bandwidth part based on a first rule, including:

[0114] If the second initial access bandwidth portion does not exceed the access bandwidth capability of the first terminal, the second initial access bandwidth portion is used as the first initial access bandwidth portion.

[0118] Optionally, the determining, according to the access bandwidth capability of the first terminal, a portion of the bandwidth of the second initial access bandwidth as a portion of the first initial access bandwidth includes:

[0119] The starting frequency position of the second initial access bandwidth part is used as the starting position of the first initial access bandwidth part, and the end position of the first initial access bandwidth is determined based on the access bandwidth capability of the first terminal as the offset of the starting frequency position.

[0120] It is worth noting that the aforementioned step 201 and the aforementioned optional steps can be combined arbitrarily.

[0121] Figure 3 is a flow chart showing a method for configuring an initial access bandwidth portion according to an exemplary embodiment. The method may be executed by the aforementioned access network device, see Figure 3 , the method comprises the following steps:

[0122] In step 301, remaining main system information RMSI is generated, where the RMSI includes first configuration information for indicating an initial access bandwidth part of a second terminal and second configuration information for indicating an initial access bandwidth part of a first terminal, where the access bandwidth capability of the first terminal is less than the access bandwidth capability of the second terminal;

[0123] In step 302, the RMSI is sent.

[0124] Figure 4 FIG. 1 is a flow chart of a method for determining an initial access bandwidth portion according to an exemplary embodiment. The method may be Figure 1 The access network equipment and terminals in the Figure 4In 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 the access bandwidth capability of the second terminal. Figure 4 , the method comprises the following steps:

[0125] In step 401, the access network device sends the configuration information and RMSI of CORESET#0.

[0126] The configuration information of CORESET#0 is used to indicate the frequency resource 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.

[0127] The terminal can obtain the PDCCH that schedules system messages (such as SIB1, RMSI, etc.) according to the configuration information of CORESET#0.

[0128] After obtaining the PDCCH associated with the RMSI, the terminal obtains the Physical Downlink Shared Channel (PDSCH) corresponding to the PDCCH and parses the RMSI from the PDSCH data.

[0129] 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.

[0130] In step 402, the first terminal determines a first initial access bandwidth portion according to configuration information of CORESET#0.

[0131] In a possible implementation, step 402 includes: determining the frequency resource where CORESET#0 is located as the first initial access bandwidth part. That is, determining the frequency size and frequency bandwidth occupied by CORESET#0 as the first initial access bandwidth part.

[0132] 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 part, and using the access bandwidth capability of the first terminal as an offset of the starting frequency position to determine the end position of the first initial access bandwidth.

[0133] In step 403, the second terminal receives the configuration information and RMSI of CORESET#0.

[0134] In step 404, the second terminal determines a second initial access bandwidth portion according to the RMSI.

[0135] In step 404, if the RMSI includes the first configuration information, the initial access bandwidth portion indicated by the first configuration information is used as the second initial access bandwidth portion. Alternatively, if the RMSI does not include the first configuration information, the second initial access bandwidth portion is determined according to the configuration information of CORESET#0. That is, the frequency resource where the control resource set 0 is located is determined as the second initial access bandwidth portion.

[0136] For example, Figure 4 The method shown can be used to determine the 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.

[0137] It should be noted that in Figure 4 In the method shown, the first rule is to determine the first initial access bandwidth part only according to the configuration information of CORESET#0 (see step 402). The second rule is: if the RMSI includes the first configuration information, the initial access bandwidth part indicated by the first configuration information is used as the second initial access bandwidth part; if the RMSI does not include the first configuration information, the second initial access bandwidth part is determined 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.

[0138] In the embodiment of the present disclosure, regardless of whether the RMSI includes the first configuration information, and regardless of whether the initial access bandwidth part indicated by the first configuration information exceeds the access bandwidth capability of the first terminal, the first terminal determines the first initial access bandwidth part according to the configuration information of CORESET#0. Since the frequency resources where CORESET#0 is located are relatively small, the first initial bandwidth part determined according to the configuration information of CORESET#0 will not exceed the access bandwidth capability of the first terminal, which is conducive to the normal operation of the first terminal.

[0139] Figure 5 is a flow chart of a method for determining an initial access bandwidth portion according to an exemplary embodiment. The method can be performed by the aforementioned access network device and the terminal together. Figure 5 In 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 the access bandwidth capability of the second terminal. Figure 5 , the method comprises the following steps:

[0140] In step 501, the access network device sends RMSI.

[0141] In one possible implementation, the RMSI includes first configuration information for indicating the initial access bandwidth portion of the second terminal and 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 but does not include the first configuration information.

[0142] 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.

[0143] 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 smaller than the initial access bandwidth portion indicated by the first configuration information.

[0144] In step 502, the first terminal receives the RMSI.

[0145] In step 503, the first terminal determines a first initial access bandwidth part according to the second configuration information.

[0146] That is, the initial access bandwidth part indicated by the second configuration information is used as the first initial access bandwidth part.

[0147] In step 504, the second terminal receives the RMSI.

[0148] In step 505, the second terminal determines a second initial access bandwidth portion according to the RMSI.

[0149] The relevant contents of step 505 can refer to the aforementioned step 404, and the detailed description is omitted here.

[0150] For example, Figure 5 The method shown can be used to determine the initial downlink access bandwidth part, or the initial uplink access bandwidth part. That is, the first initial access bandwidth part and the second initial access bandwidth part are both initial downlink access bandwidth parts, or both are initial uplink access bandwidth parts.

[0151] It should be noted that in Figure 5 In 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.

[0152] In the embodiment of the present disclosure, for the first terminal with poor access bandwidth capability, the second configuration information is set separately to ensure that 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, which is conducive to the normal operation of the first terminal.

[0153] Figure 6 is a flow chart of a method for determining an initial access bandwidth portion according to an exemplary embodiment. The method can be performed by the aforementioned access network device and the terminal together. Figure 6 In 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 the access bandwidth capability of the second terminal. Figure 6 , the method comprises the following steps:

[0154] In step 601, the access network device sends the configuration information and RMSI of CORESET#0.

[0155] In one possible implementation, the RMSI includes at least one of 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. In another possible implementation, the RMSI includes neither the first configuration information nor the second configuration information. That is, the access network device may configure the first configuration information in the RMSI or not; similarly, the access network device may configure the second configuration information in the RMSI or not.

[0156] In step 602, the first terminal receives RMSI.

[0157] In step 603, the first terminal determines a first initial access bandwidth part according to the RMSI.

[0158] This step 603 may include: if the second configuration information in the RMSI is not missing (that is, the RMSI includes the second configuration information), determining 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 (that is, the RMSI does not include the second configuration information), determining the first initial access bandwidth part according to the configuration information of CORESET#0.

[0159] Here, the method of determining the first initial access bandwidth according to the second configuration information in the RMSI can be referred to step 503; the method of determining the first initial access bandwidth part according to the configuration information of CORESET#0 can be referred to step 402, and detailed description is omitted here.

[0160] In step 604, the second terminal receives the RMSI.

[0161] In step 605, the second terminal determines a second initial access bandwidth portion according to the RMSI.

[0162] The relevant contents of step 605 can refer to the aforementioned step 404, and the detailed description is omitted here.

[0163] Optionally, Figure 6 The method shown can be used to determine the 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.

[0164] It should be noted that in Figure 6 In the method shown, the first rule is: determine the first initial access bandwidth part according to the second configuration information (see step 603). 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, that is, the first rule and the second rule are completely different.

[0165] In the embodiment of the present disclosure, the second configuration information is set separately for the first terminal with poor access bandwidth capability. When the second configuration information is included in the RMSI, 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. When the second configuration information is not included in the RMSI, the first terminal determines the first initial access bandwidth part according to the configuration information of CORESET#0. Since the frequency resources where CORESET#0 is located are small, the first initial bandwidth part 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 part determined by the first terminal will not exceed the access bandwidth capability of the first terminal, which is conducive to the normal operation of the first terminal.

[0166] Figure 7 is a flow chart of a method for determining an initial access bandwidth portion according to an exemplary embodiment. The method can be performed by the aforementioned access network device and the terminal together. Figure 7 In 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 the access bandwidth capability of the second terminal. Figure 7 , the method comprises the following steps:

[0167] In step 701, the access network device sends the configuration information and RMSI of CORESET#0.

[0168] In step 702, the first terminal receives RMSI.

[0169] In step 703, the first terminal determines a second initial access bandwidth part according to the first configuration information;

[0170] In step 704, the first terminal determines, according to the access bandwidth capability of the first terminal, a portion of the second initial access bandwidth as a portion of the first initial access bandwidth.

[0171] Exemplarily, step 704 may include: the first terminal uses the starting frequency position of the second initial access bandwidth part as the starting position of the first initial access bandwidth part, and uses the access bandwidth capability of the first terminal as the offset of the starting frequency position to determine the end position of the first initial access bandwidth.

[0172] In step 705, the second terminal receives the RMSI.

[0173] In step 706, the second terminal determines a second initial access bandwidth portion according to the RMSI.

[0174] Optionally, Figure 7 The method shown can be used to determine the initial downlink access bandwidth part, or the initial uplink access bandwidth part. That is, the first initial access bandwidth part and the second initial access bandwidth part are both initial downlink access bandwidth parts, or both are initial uplink access bandwidth parts.

[0175] When the second initial access bandwidth part is the initial downlink access bandwidth, the step 706 may refer to the aforementioned step 404 .

[0176] When the second initial access bandwidth part is the initial uplink access bandwidth part, step 706 may include: taking the initial access bandwidth part indicated by the first configuration information in the RMSI as the second initial access bandwidth part.

[0177] It should be noted that in Figure 7 In the method shown, the first rule is: determine the first initial access bandwidth portion according to the second configuration information (see steps 703 and 704). The second rule is shown in step 706, that is, the first rule and the second rule are completely different.

[0178] In the embodiment of the present disclosure, for a first terminal with poor access bandwidth capability, a portion of the second initial access bandwidth is determined as a portion of the first initial access bandwidth based on the access bandwidth capability of the first terminal, so that 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 conducive to the normal operation of the first terminal.

[0179] 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 performed by the aforementioned access network device and the terminal together. Figure 8 In 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 the access bandwidth capability of the second terminal. Figure 8 , the method comprises the following steps:

[0180] In step 801, the access network device sends the configuration information and RMSI of CORESET#0.

[0181] In step 802, the first terminal receives RMSI.

[0182] In step 803, the first terminal determines a second initial access bandwidth part according to the first configuration information.

[0183] In step 804, the first terminal compares the second initial access bandwidth portion with the access bandwidth capability of the first terminal.

[0184] If the second initial access bandwidth portion exceeds the access bandwidth capability of the first terminal, step 805 is executed; if the second initial access bandwidth portion does not exceed the access bandwidth capability of the first terminal, step 806 is executed.

[0185] In step 805, the first terminal determines the first initial access bandwidth part according to the configuration information of CORESET#0.

[0186] For the relevant content of step 805, please refer to the aforementioned step 402.

[0187] In some embodiments of the present disclosure, step 805 may be replaced by the aforementioned step 503, or the aforementioned step 603, or the aforementioned steps 703 and 704.

[0188] It should be noted that when step 805 is replaced by the aforementioned step 503 or replaced by steps 703 and 704, the first initial access bandwidth part can be the initial uplink access bandwidth part or the initial downlink access bandwidth part; when step 805 is replaced by the aforementioned step 603, the first initial access bandwidth part is the initial downlink access bandwidth part.

[0189] In step 806, the first terminal uses the second initial access bandwidth part as the first initial access bandwidth part.

[0190] Through step 803 to step 806, it can be achieved that the first initial access bandwidth part is determined according to the size relationship between the second initial access bandwidth part and the access bandwidth capability of the first terminal.

[0191] In this embodiment, the manner in which the second terminal determines the second initial access bandwidth portion can be referred to in the aforementioned step 404, which will not be described in detail herein.

[0192] It should be noted that in Figure 8 In 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.

[0193] The following is an exemplary description of the determination of the initial downlink bandwidth part (initial DL BWP) and the initial uplink bandwidth part (initial UL BWP).

[0194] 1. Determination of initial DL BWP

[0195] When the initial DL BWP configured by the 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 the RMSI;

[0196] When 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 in any of the following three ways:

[0197] The first type: the first terminal determines the initial DL BWP according to predefined rule 1 or 2

[0198] Predefined rule 1: Set the frequency size and frequency bandwidth occupied by CORESET#0 as the user's initial DLBWP;

[0199] Predefined rule 2: Taking the starting frequency position of CORESET#0 as the starting point, the end point of the initial DL BWP is determined according to the bandwidth capability of the first terminal.

[0200] The second type is that the access network device additionally configures an Initial DL BWP_extra (ie, second configuration information) for the first terminal (also referred to as NR-lite) in the RMSI, and the first terminal uses the initial DL BWP_extra as the initial DL BWP.

[0201] The third method is a combination of the first and second methods. The access network device can additionally configure Initial DLBWP_extra in the RMSI, but the access network device may 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.

[0202] 2. Determination of initial UL BWP

[0203] When the initial UL BWP configured by the 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 the RMSI. When 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 in any of the following three ways:

[0204] The first method is to determine the initial UL BWP based on predefined rules.

[0205] Predefined rules: The starting frequency position of the initial UL BWP configured by the RMSI is used as the starting point, and the end point of the initial UL BWP is determined according to the access bandwidth capability of the first terminal.

[0206] The second type is that the access network device additionally configures an Initial UL BWP_extra (ie, second configuration information) for the first terminal (also referred to as NR-lite) in the RMSI, and the first terminal uses the initial UL BWP_extra as the initial UL BWP.

[0207] The third method is a combination of the first and second methods. The access network device can configure the Initial ULBWP_extra in the RMSI, but the access network device may 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.

[0208] In the embodiment of the present disclosure, for a 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, the first initial access bandwidth part is determined according to the configuration information of CORESET#0, or the first initial access bandwidth part is determined according to the second configuration information, and a partial bandwidth of the second initial access bandwidth is determined to be the first initial access bandwidth part according to the access bandwidth capability of the first terminal, so that when 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 conducive to the normal operation of the first terminal.
