Frequency domain resource determination method and apparatus, and terminal, network device and storage medium

Abstract

The present disclosure relates to the technical field of communications, and specifically relates to a frequency domain resource determination method and apparatus, and a terminal, a network device and a storage medium. The frequency domain resource determination method comprises: on the basis of a predefined rule or indication information of a network device, determining at least one operating bandwidth within a frequency domain range corresponding to a bandwidth of a serving cell. In the present disclosure, since an operating bandwidth is within a frequency domain range corresponding to a bandwidth of a serving cell, the operating bandwidth may be smaller than the bandwidth of the serving cell, and therefore instead of determining a communication bandwidth on the basis of the bandwidth of the serving cell, the terminal can determine, on the basis of a predefined rule or indication information of a network device, at least one operating bandwidth within the frequency domain range corresponding to the bandwidth of the serving cell, and then communicate with the network device in the working bandwidth.

Description

Frequency domain resource determination method and apparatus, terminal, network device, and storage medium TECHNICAL FIELD

[0001] The present disclosure relates to the technical field of communication, and in particular, to a frequency domain resource determination method, a frequency domain resource determination apparatus, a terminal, a network device, a communication system, and a storage medium. BACKGROUND

[0002] In a 4G LTE (Long Term Evolution) system, the system bandwidth of a cellular system is fixed, and depends on the frequency band and configuration of an operator. For example, the working bandwidth is 1.25 MHz, 2.5 MHz, 5 MHz, 10 MHz, or 20 MHz. Once deployed, the system bandwidth of a serving cell remains fixed. Correspondingly, the working bandwidth of a terminal side is also fixed.

[0003] A fixed system, although capable of simplifying protocol design and product implementation complexity, also brings certain limitations to the system. For example, in order to expand the available bandwidth when the system capacity needs to be increased, the CA (Carrier Aggregation) technology must be used, which itself leads to an increase in complexity. For example, in the presence of a continuous large bandwidth, the continuous large bandwidth needs to be cut into multiple small bandwidths that meet the LTE bandwidth limit, and the guard band between different carriers needs to be ensured to reduce the interference in the frequency domain between small bandwidths, which leads to a reduction in the utilization rate of spectrum resources.

[0096] In some embodiments, in a system of 5G NR (New Radio) and subsequent versions (for example, 6G), in order to achieve the designed technical indicators, a maximum of 400MHz or even larger continuous spectrum is supported. If the communication bandwidth (for example, the bandwidth actually used for communication by the terminal) is still determined based on 4G LTE (Long Term Evolution) with a fixed physical bandwidth (for example, the available continuous bandwidth, such as the above-mentioned 400MHz), the following problems will be encountered:

[0097] The radio frequency requirement of the terminal is extremely high, and the terminal needs to define the radio frequency indicators according to the maximum working bandwidth;

[0098] The coverage performance of the terminal is negatively affected;

[0099] The energy consumption of the terminal side is negatively affected;

[0100] The energy consumption of the network device side is negatively affected;

[0101] The resource allocation and spectrum efficiency of the system are negatively affected.

[0102] FIG. 2 is an interaction schematic diagram of a frequency domain resource determination method according to an embodiment of the present disclosure.

[0103] In some embodiments, the terminal can determine at least one working bandwidth in the frequency domain range corresponding to the bandwidth (for example, the system bandwidth) of the serving cell according to a predefined rule or the indication information of the network device.

[0104] As shown in FIG. 2, the frequency domain resource determination method can include the following steps:

[0105] In step S201, the network device can send indication information to the terminal.

[0106] In some embodiments, the terminal can receive the indication information.

[0107] In some embodiments, the indication information is used to instruct the terminal to determine at least one working bandwidth in the frequency domain range corresponding to the bandwidth of the serving cell.

[0108] In step S202, the terminal determines at least one working bandwidth in the frequency domain range corresponding to the bandwidth of the serving cell according to the indication information.

[0109] In some embodiments, the terminal can determine at least one working bandwidth in the frequency domain range corresponding to the bandwidth of the serving cell according to a predefined rule.

[0110] In some embodiments, the network device can determine at least one working bandwidth in the frequency domain range corresponding to the bandwidth of the serving cell according to a predefined rule.

[0111] In some embodiments, the terminal can communicate with the network device in the at least one working bandwidth, for example, perform uplink communication, downlink communication, etc., and the type of the communication is not limited by the present disclosure.

[0112] According to embodiments of the present disclosure, since the working bandwidth is in the frequency domain range corresponding to the bandwidth of the serving cell, the working bandwidth can be smaller than the bandwidth of the serving cell, so that the terminal does not have to determine the communication bandwidth based on the bandwidth of the serving cell, but can determine at least one working bandwidth in the frequency domain range corresponding to the bandwidth of the serving cell according to a predefined rule or indication information of the network device, and then communicate with the network device on the working bandwidth.

[0113] Compared with the terminal determining the communication bandwidth based on the bandwidth of the serving cell, the terminal communicating on the working bandwidth has relatively low requirements on radio frequency, relatively good coverage performance, and relatively low energy consumption.

[0114] Moreover, the network device can also communicate with the terminal on the working bandwidth, which has relatively low energy consumption for the network device, and the network device can flexibly configure the working bandwidth of the terminal based on the indication information, which is beneficial to improving the resource allocation and spectrum efficiency of the system.

[0115] In some embodiments, the bandwidth of the serving cell, for example, can be a system bandwidth, and the network device can provide the terminal with system bandwidth information of at least one serving cell based on a predefined manner or configuration. For example, the system bandwidth of the serving cell is the frequency domain resource position occupied by the serving cell in the deployment frequency band. For example, the network device can provide corresponding services for all service requirements in the system bandwidth.

[0116] It should be noted that the definition, size, and characteristics (for example, whether continuous) of the system bandwidth occupied by the serving cell are not limited by the present disclosure.

[0117] The following will illustrate the case where the terminal determines at least one working bandwidth in the frequency domain range corresponding to the bandwidth of the serving cell according to the indication information through several embodiments.

[0118] In some embodiments, the indication information includes at least one of the following:

[0119] broadcast signaling;

[0120] groupcast signaling;

[0121] terminal dedicated (UE-dedicated) signaling;

[0122] semi-static signaling;

[0123] Dynamic signaling.

[0124] In some embodiments, the broadcast signaling comprises at least one of:

[0125] a Master Information Block (MIB);

[0126] a System Information Block (SIB), such as SIB1, SIBn (n is an integer greater than 1), etc.

[0127] a Downlink Control Information (DCI) in a Common Search Space (CSS).

[0128] In some embodiments, the groupcast signaling comprises at least one of: a groupcast DCI; a groupcast Physical Downlink Shared Channel (PDSCH).

[0129] In some embodiments, the network device can configure a BandWidth Part (BWP) for the terminal, and the terminal communicates based on the BWP, which is beneficial to increase the flexibility of the network device in resource allocation, and the network device can adjust the activated BWP according to the traffic load to achieve the purpose of power saving.

[0130] It should be noted that the broadcast signaling can be directed to all terminals in a cell, and thus can also be referred to as cell-specific signaling, and the groupcast signaling can be directed to a specific group of terminals, and thus can also be referred to as group common signaling.

[0131] However, the problem is that the current adjustment of the BWP, such as adjusting the activated BWP, mainly includes three ways:

[0132] The first way is to adjust based on Radio Resource Control (RRC) signaling. This way is a semi-static adjustment way.

[0133] The second way is to adjust based on a timer. The terminal and the base station determine whether to perform switching between specific BWPs according to whether the timer is timed out.

[0134] The third way is to adjust based on DCI. The network device indicates the target BWP through the BWP indicator carried in the non-fallback DCI.

[0135] As can be seen, in the above three manners, the manner in which the network device indicates the terminal mainly includes indicating through RRC signaling and indicating through non-fallback DCI. However, both the RRC signaling and the non-fallback DCI belong to unicast signaling, which limits the operation of adjusting the BWP to some extent. For example, the network device adjusts the BWP for terminals one by one through unicast signaling, which is relatively low in efficiency and relatively high in signaling overhead.

[0136] According to embodiments of the present disclosure, the network device can indicate the terminal to determine at least one working bandwidth in the frequency domain range corresponding to the bandwidth of the serving cell through broadcast signaling and / or groupcast signaling. Compared with the manner of indicating the BWP through unicast signaling, the network device can indicate multiple terminals to determine the working bandwidth by sending broadcast signaling and / or groupcast signaling once, without indicating the working bandwidth for terminals one by one, which is relatively high in efficiency and relatively low in signaling overhead.

[0137] In some embodiments, the DCI in the CSS is scrambled by a first Radio Network Temporary Identity (RNTI).

[0138] In some embodiments, the first RNTI is the same as an RNTI used to scramble DCI for other purposes.

[0139] In some embodiments, the first RNTI is a RNTI dedicated to scrambling DCI for indicating the working bandwidth.

[0140] In some embodiments, the DCI in the CSS indicates the working bandwidth through a newly defined information field.

[0141] In some embodiments, the DCI in the CSS indicates the working bandwidth through a reserved bit (e.g., a repurposed reserved bit).

[0142] In some embodiments, the method further includes determining the terminal indicated by the groupcast signaling according to a configuration of the network device and / or a terminal identity (e.g., a UE ID, which can correspond to a specific RNTI value).

[0143] For example, the network device can send a configuration to the terminal to configure the terminal to receive the groupcast signaling.

[0144] For example, the terminal identity can be carried in the groupcast signaling. After receiving the groupcast signaling, the terminal can determine whether the groupcast signaling is used to indicate the working bandwidth according to the terminal identity carried therein. For example, if the terminal identity carried in the groupcast signaling is the same as the identity of the terminal receiving the groupcast signaling, it can be determined that the groupcast signaling is used to indicate the working bandwidth; if the terminal identity carried in the groupcast signaling is not the same as the identity of the terminal receiving the groupcast signaling, it can be determined that the groupcast signaling is not used to indicate the working bandwidth.

[0145] For example, the multicast signaling can be scrambled by a specific RNTI value corresponding to the terminal identity. After receiving the multicast signaling, the terminal can attempt to descramble the multicast signaling, and determine whether the multicast signaling is used to indicate the operating bandwidth according to the descrambling result. For example, the terminal receiving the multicast signaling can attempt to descramble the multicast signaling according to the RNTI value corresponding to the terminal identity. In the case of successful descrambling, it can be determined that the multicast signaling is used to indicate the operating bandwidth. In the case of failed descrambling, it can be determined that the multicast signaling is not used to indicate the operating bandwidth.

[0146] In some embodiments, the multicast DCI is a DCI dedicated to indicating the operating bandwidth (e.g., specifically used to carry information indicating the operating bandwidth).

[0147] In some embodiments, the multicast DCI is a DCI used to indicate the operating bandwidth and other information (e.g., used to carry information indicating the operating bandwidth and other control information in the same DCI).

[0148] In some embodiments, the terminal-specific signaling includes at least one of the following:

[0149] RRC signaling;

[0150] DCI;

[0151] Media Access Control Control Element (MAC CE).

[0152] In some embodiments, the DCI is scrambled by a unique identity of the terminal, for example, the unique identity of the terminal can include a Cell-Radio Network Temporary Identifier (C-RNTI).

[0153] In some embodiments, the DCI is a DCI dedicated to indicating the operating bandwidth.

[0154] In some embodiments, the DCI included in the terminal-specific signaling can be a DCI in a terminal-specific search space (USS), or the DCI can also be transmitted in the CSS.

[0155] In some embodiments, the indication information is used to indicate at least one of the following:

[0156] a starting position of the operating bandwidth;

[0157] an ending position of the operating bandwidth;

[0158] a length of the operating bandwidth;

[0159] a scaling factor of the reference frequency domain range relative to the operating bandwidth;

[0160] an offset of the reference frequency domain range relative to the operating bandwidth;

[0161] an association between a service type and the operating bandwidth.

[0162] For example, the terminal can determine the operating bandwidth in the frequency domain range corresponding to the bandwidth of the serving cell according to the start position and the end position of the operating bandwidth, for example, the operating bandwidth is the bandwidth from the start position to the end position.

[0163] For example, the terminal can determine the operating bandwidth in the frequency domain range corresponding to the bandwidth of the serving cell according to the start position and the length of the operating bandwidth, for example, the operating bandwidth is the bandwidth from the start position and lasting the length.

[0164] For example, the terminal can determine the operating bandwidth in the frequency domain range corresponding to the bandwidth of the serving cell according to the scaling factor of the reference frequency domain range. The terminal can scale the reference frequency domain range based on the scaling factor to determine the scaled frequency domain range as the operating bandwidth.

[0165] For example, the terminal can determine the operating bandwidth in the frequency domain range corresponding to the bandwidth of the serving cell according to the scaling factor of the reference frequency domain range. The terminal can offset the reference frequency domain range based on the offset to determine the offset frequency domain range as the operating bandwidth.

[0166] For example, the reference frequency domain range (which can be a piece of frequency domain range, or multiple pieces of frequency domain range) can be configured by the network device, or determined by the terminal based on a pre-defined rule (for example, a protocol agreement).

[0167] For example, the terminal can determine the operating bandwidth in the frequency domain range corresponding to the bandwidth of the serving cell according to the association between the service type and the operating bandwidth. When the terminal needs to perform a certain service, it can determine the corresponding bandwidth in the above association as the operating bandwidth according to the type of the service.

[0168] It should be noted that the content indicated by the indication information is not limited to the content described in the above embodiments, and other content can also be indicated, and the present disclosure does not limit this. For example, the indication information can indicate the numbers of the candidate bandwidths, and the terminal can determine the operating bandwidth according to the numbers of the indication information. In the frequency domain range corresponding to the bandwidth of the serving cell, there can be 6 candidate bandwidths, which are candidate bandwidth #1, candidate bandwidth #2, candidate bandwidth #3, candidate bandwidth #4, candidate bandwidth #5, and candidate bandwidth #6. The indication information can indicate numbers 2 and 3, and the terminal can determine candidate bandwidth #2 and candidate bandwidth #3 as the operating bandwidth according to the indication information.

[0169] In some embodiments, the semi-static signaling (e.g., RRC signaling) is used to indicate a plurality of candidate frequency domain ranges (e.g., candidate bandwidths), and the dynamic signaling (e.g., DCI, MAC CE) is used to indicate at least one active bandwidth in the plurality of candidate frequency domain ranges.

[0170] For example, after receiving the semi-static signaling, the terminal can determine the plurality of candidate frequency domain ranges, and then after receiving the dynamic signaling, the terminal can determine the at least one bandwidth indicated by the dynamic signaling in the plurality of candidate frequency domain ranges as the active bandwidth.

[0171] In some embodiments, the terminal performs a communication operation in the active bandwidth indicated by the dynamic signaling, and / or determines that the candidate frequency domain ranges outside the active bandwidth indicated by the dynamic signaling are unavailable.

[0172] For example, for the active bandwidth indicated by the dynamic signaling, the terminal can perform a communication operation in the active bandwidth, e.g., communicate with the network device.

[0173] For example, for the candidate frequency domain ranges outside the active bandwidth indicated by the dynamic signaling, the terminal can determine that these frequency domain ranges are unavailable and does not perform a communication operation in these frequency domain ranges.

[0174] In some embodiments, the predefined rule includes an association relationship between the service type and the active bandwidth.

[0175] For example, the predefined rule can specify an association relationship between the service type and the active bandwidth, and when the terminal needs to perform a certain service, the terminal can determine the corresponding bandwidth as the active bandwidth according to the type of the service in the association relationship specified by the predefined rule.

[0176] It should be noted that the disclosure does not limit the definition, identification, indication, confirmation, etc. of the service type, for example, the service type can be determined by an explicit signaling indication, for example, the service type can be determined in a predefined manner, for example, different service types can be corresponded to different active bandwidths, etc. In this embodiment, when the service type is clear, the active bandwidth can be determined according to the corresponding relationship between the service type and the active bandwidth.

[0177] In some embodiments, the service type includes at least one of the following:

[0178] Artificial Intelligence (AI) related services;

[0179] Integrated Sensing and Communication (ISAC) related services;

[0180] Non Terrestrial Network (NTN) related service;

[0181] Hyper reliable and low latency communication (HRLLC) related service, Ultra reliable and low latency communication (URLLC) related service;

[0182] Immersive communication related service;

[0183] Internet of Things (IoT) related service;

[0184] Ubiquitous communication related service;

[0185] Sustainability service.

[0186] For example, in the association relationship between the service type and the working bandwidth, one service type can correspond to one or more working bandwidths.

[0187] For example, in the frequency domain range corresponding to the bandwidth of the serving cell, there can be 6 candidate bandwidths, candidate bandwidth #1, candidate bandwidth #2, candidate bandwidth #3, candidate bandwidth #4, candidate bandwidth #5, and candidate bandwidth #6.

[0188] For example, in the association relationship between the service type and the working bandwidth, the AI related service corresponds to the candidate bandwidth #1, and the terminal can take the candidate bandwidth #1 as the working bandwidth when performing the AI related service, and perform the AI related service on the working bandwidth.

[0189] For example, in the association relationship between the service type and the working bandwidth, the NTN related service corresponds to the candidate bandwidth #5 and the candidate bandwidth #6, and the terminal can take the candidate bandwidth #5 and the candidate bandwidth #6 as the working bandwidth when performing the NTN related service, and perform the NTN related service on the working bandwidth.

[0190] It should be noted that the present disclosure does not limit the mutual relationship between different bandwidths corresponding to different service types, for example, different bandwidths corresponding to different service types can not overlap, or partially overlap, or completely overlap in the frequency domain. In addition, there can be a guard band between different bandwidths corresponding to different service types, or there can be no guard band, and the present disclosure does not limit this.

[0191] In some embodiments, the association between the service type and the operating bandwidth is determined based on at least one of the following:

[0192] a size of a bandwidth of the serving cell;

[0193] a type of the serving cell, for example including Frequency Division Duplexing (FDD), Time Division Duplexing (TDD), and the like;

[0194] a frequency range to which a bandwidth of the serving cell belongs, for example the frequency range including FR1, FR2, FR3, and the like.

[0195] For example, for the same type of service, the network device can indicate to the terminal the association between multiple service types and operating bandwidths, or a predefined rule can specify the association between multiple service types and operating bandwidths. In this case, the terminal can further determine the association to be adopted.

[0196] For example, the association between the service type and the operating bandwidth is determined based on the type of the serving cell. For example, when the type of the serving cell is FDD, the association between the service type and the operating bandwidth is a relatively large one of multiple association relationship identifiers; when the type of the serving cell is TDD, the association between the service type and the operating bandwidth is a relatively small one of multiple association relationship identifiers.

[0197] For example, for AI-related services, a predefined rule specifies the association between two AI-related services and operating bandwidths, which are association relationship #1 (identified as 1) and association relationship #2 (identified as 2), respectively. When the terminal determines that the type of the serving cell is FDD, it can determine the operating bandwidth according to the association relationship #2; when it determines that the type of the serving cell is TDD, it can determine the operating bandwidth according to the association relationship #1.

[0198] In some embodiments, the frequency range (e.g., operating bandwidth) in which the terminal operates includes at least a continuous or discontinuous frequency resource range in which the terminal performs signal reception, signal transmission, measurement, and the like. The terminal does not expect to perform transceiving and / or measurement operations on frequency resources outside the resource range in which it operates. For example, the signal can include at least one of the following: data signal, control signal, reference signal.

[0199] In some embodiments, the terminal has loaded relevant configuration information of multiple bandwidths (e.g., each candidate bandwidth) in the frequency range corresponding to the bandwidth of the serving cell.

[0200] In the embodiment of introducing BWP, the BWP is adjusted by DCI. Since the DCI belongs to dynamic signaling, in order to avoid communication conflicts, a series of timing related technologies need to be specified.

[0201] Although the BWP adjustment mechanism can improve flexibility, it also increases the complexity of implementation and the redundant design of protocol flow. From the perspective of protocol stack, the BWP can be regarded as a parameter set. From the perspective of the terminal, before performing data transmission and reception, a series of operations such as configuration update and radio frequency parameter adjustment need to be completed.

[0202] For example, taking the adjustment of BWP based on DCI as an example, the switching time of BWP includes DCI parsing time, terminal side RRC signaling update and parsing time, configuration update time and radio frequency device adjustment time. Therefore, the minimum switching time needs to be defined for BWP switching, and data transmission and reception are not allowed within the switching time, which not only increases the complexity of time domain resource allocation, but also wastes a part of time domain resources.

[0203] According to the present embodiment, the terminal has loaded (for example, loaded when starting, or loaded when accessing a service cell, or loaded by reading protocol agreed information, and the present disclosure does not limit the loading time) the related configuration information of a plurality of bandwidths in the frequency domain range corresponding to the bandwidth of the service cell before determining the working bandwidth according to the predefined rule or indication information.

[0204] For example, there are 6 candidate bandwidths in the frequency domain range corresponding to the bandwidth of the service cell, and the terminal can load the related configuration information of the 6 candidate bandwidths before determining the working bandwidth according to the predefined rule or indication information. Among them, the related configuration information can include the configuration required by the terminal for communication in the plurality of bandwidths.

[0205] For example, the working bandwidth determined by the terminal according to the predefined rule or indication information is candidate bandwidth #1 of the 6 candidate bandwidths. Even if the original working bandwidth of the terminal is other bandwidths (for example, candidate bandwidth #2 to candidate bandwidth #6) other than candidate bandwidth #1, since the terminal has loaded the related configuration information of candidate bandwidth #1 when communicating on the original working bandwidth, the terminal can directly communicate based on the related configuration information of candidate bandwidth #1 when determining the new working bandwidth as candidate bandwidth #1, without updating the configuration (for example, updating the configuration from the related configuration of other bandwidths to the related configuration of candidate bandwidth #1), thereby reducing the time of changing the working bandwidth, which is conducive to reducing the complexity of time domain resource allocation and alleviating the waste of time domain resources.

[0206] In some embodiments, the terminal communicates based on the radio frequency parameters corresponding to the bandwidth of the service cell.

[0207] According to the embodiment, the terminal communicates based on the radio frequency parameters corresponding to the bandwidth of the serving cell before determining the working bandwidth according to the predefined rule or the indication information, instead of communicating based on the radio frequency parameters of a certain working bandwidth. Since the bandwidth of the serving cell contains all the working bandwidths, the radio frequency parameters of the bandwidth of the serving cell are applicable to any working bandwidth.

[0208] For example, the bandwidth of the serving cell corresponds to a frequency domain range in which there are 6 candidate bandwidths, and the terminal communicates based on the radio frequency parameters corresponding to the bandwidth of the serving cell before determining the working bandwidth according to the predefined rule or the indication information.

[0209] For example, the working bandwidth determined by the terminal according to the predefined rule or the indication information is candidate bandwidth #1 of the 6 candidate bandwidths, and even if the original working bandwidth of the terminal is another bandwidth (for example, candidate bandwidth #2 to candidate bandwidth #5) other than candidate bandwidth #1, since the terminal communicates based on the radio frequency parameters corresponding to the bandwidth of the serving cell and the radio frequency parameters of the bandwidth of the serving cell are applicable to any working bandwidth, the terminal can continue to communicate on candidate bandwidth #1 based on the radio frequency parameters used for communication on the other bandwidths when switching from the original working bandwidth to the new working bandwidth, without having to adjust the radio frequency parameters again, thereby reducing the time for changing the working bandwidth and facilitating reduction of the complexity of allocation of time domain resources and alleviation of waste of time domain resources.

[0210] In some embodiments, the working bandwidth determined by the terminal according to the predefined rule or the indication information can be one or more working bandwidths (for example, one or more candidate bandwidths can be determined as working bandwidths), and the terminal can communicate on at least one determined working bandwidth. For example, the terminal can perform data, signal transceiving and measurement operations on one or more working bandwidths.

[0211] In some embodiments, when the network device indicates the working bandwidth through the DCI (groupcast DCI or unicast DCI), the frequency domain resource allocation (FDRA) field in the DCI can be determined according to a fixed reference bandwidth, for example, the reference bandwidth can be the system bandwidth of the serving cell, or the reference bandwidth can be determined according to a predefined other bandwidth.

[0212] FIG. 3 is a schematic diagram of a working bandwidth according to an embodiment of the present disclosure.

[0213] As shown in FIG. 3, the bandwidth of the serving cell can correspond to a frequency domain range containing 6 candidate bandwidths, candidate bandwidth #1, candidate bandwidth #2, candidate bandwidth #3, candidate bandwidth #4, candidate bandwidth #5, and candidate bandwidth #6.

[0214] The longitudinal direction in FIG. 3 can correspond to the frequency domain, and the transverse direction can not correspond to any quantity, but is only for the sake of clarity to arrange the candidate bandwidths along the transverse direction to show several candidate bandwidths.

[0215] It should be noted that the number of candidate bandwidths in the frequency domain range corresponding to the bandwidth of the serving cell is not limited to the number described in the foregoing examples, and can be other numbers. The frequency domain relationship between different candidate bandwidths can include partial overlap, complete overlap, no overlap, etc., and the present disclosure does not limit this. The determination mechanism of the candidate bandwidth is also not limited by the present disclosure, and can be configured by the network device or defined by a predefined rule (for example, a protocol agreement).

[0216] FIG. 4 is a schematic diagram illustrating indication of an operating bandwidth according to an embodiment of the present disclosure.

[0217] As shown in FIG. 4, the network device can indicate the operating bandwidth to the terminal through broadcast signaling and / or multicast signaling, for example, indicating the operating bandwidth as the candidate bandwidth #1 in the 6 candidate bandwidths, and then the terminal can communicate (for example, communication operations such as signal reception, signal transmission, and measurement) with the network device on the candidate bandwidth #1.

[0218] Although the terminal does not communicate on the candidate bandwidth #2 to the candidate bandwidth #6, the terminal still retains the related configuration information of these candidate bandwidths.

[0219] It should be noted that in some embodiments, when the network device does not explicitly indicate the operating bandwidth to the terminal, the network device and the terminal can communicate according to a default operating bandwidth until the network device indicates the operating bandwidth through any of the foregoing embodiments.

[0220] FIG. 5 is a schematic diagram illustrating determination of an operating bandwidth based on an association relationship according to an embodiment of the present disclosure.

[0221] As shown in FIG. 5, for example, the terminal has entered a connected state, and the terminal supports two services of service type 1 (for example, HRLLC) and service type 2 (for example, immersive communication, IC).

[0222] The terminal can determine the operating bandwidth corresponding to the two services according to the indication information of the network device or the association relationship between the service type and the operating bandwidth defined by the predefined rule. For example, the operating bandwidth corresponding to the HRLLC service is the candidate bandwidth #3 shown in FIG. 3, and the operating bandwidth corresponding to the IC service is the candidate bandwidth #2 shown in FIG. 3.

[0223] Further, the network device and the terminal can determine the operating bandwidth according to the service type at the current moment.

[0224] For example, the terminal starts to transmit the HRLLC service from the time slot slot#n, and the terminal can determine that the working bandwidth in the time slot in which the HRLLC service is transmitted is the candidate bandwidth #3.

[0225] For example, the terminal starts to transmit the IC service from the time slot slot#m, and the terminal can determine that the working bandwidth in the time slot in which the IC service is transmitted is the candidate bandwidth #2.

[0226] For example, the terminal starts to transmit the IC and HRLLC services from the time slot slot#q, and the terminal can determine that the working bandwidth in the time slot in which the IC and HRLLC services are transmitted is the candidate bandwidth #2 and the candidate bandwidth #3.

[0227] In some embodiments, when a terminal transmits multiple services as needed, if a relatively larger working bandwidth corresponding to one service contains a relatively smaller working bandwidth corresponding to another service, the terminal can transmit the multiple services based on only the relatively larger working bandwidth, or based on only the relatively smaller working bandwidth.

[0228] For example, the terminal needs to transmit the AI service and the NTN service, the working bandwidth corresponding to the AI service is the candidate bandwidth #1, the working bandwidth corresponding to the NTN is the candidate bandwidth #4, and the candidate bandwidth #1 contains the candidate bandwidth #4. In this case, the terminal can transmit the AI service and the NTN service using the candidate bandwidth #1 as the working bandwidth, or transmit the AI service and the NTN service using the candidate bandwidth #4 as the working bandwidth.

[0229] It should be noted that the present embodiment does not limit the relationship between different services, and only exemplarily describes the implementation of determining the working bandwidth. In some embodiments, when the network device and the terminal do not identify the type of service, for example, the terminal is in the initial access stage, or the terminal is in the non-connected state, in this case, the working bandwidth of the terminal is the default working bandwidth, or the network device allocates a determined working bandwidth to the terminal. The present disclosure does not limit this.

[0230] FIG. 6 is a schematic diagram illustrating an indication of a working bandwidth according to an embodiment of the present disclosure.

[0231] As shown in FIG. 6, the network device can send terminal-specific signaling, such as UE-dedicated DCI, to the terminal. The UE-dedicated DCI can indicate the working bandwidth, and the UE-dedicated DCI can also schedule data, such as PDSCH and / or PUSCH (Physical Uplink Shared Channel, PDSCH, physical uplink shared channel).

[0232] After the terminal determines the working bandwidth according to the UE-dedicated DCI, the terminal can communicate, for example, transmit and / or receive data scheduled by the UE-dedicated DCI, in the working bandwidth.

[0233] It should be noted that, in some embodiments, when the network device does not indicate the working bandwidth through the terminal-specific signaling, the network device and the terminal can communicate according to a default working bandwidth until the network device indicates the working bandwidth through any of the foregoing embodiments.

[0234] The communication method related to the embodiments of the present disclosure can include at least one of steps S201-S202. For example, step S201 can be implemented as an independent embodiment, step S202 can be implemented as an independent embodiment, steps S201+S202 can be implemented as an independent embodiment, but the present disclosure is not limited thereto.

[0235] In some embodiments, steps S201 and S202 can be exchanged in order or executed simultaneously.

[0236] In some embodiments, step S201 is optional, and one or more of the steps can be omitted or replaced in different embodiments.

[0237] In some embodiments, step S202 is optional, and one or more of the steps can be omitted or replaced in different embodiments.

[0238] In some embodiments, other optional implementations described before or after the description corresponding to FIG. 2 can be referred to.

[0239] In a first aspect, the embodiments of the present disclosure propose a frequency domain resource determination method.
