Description

Technical Field

[0001] This disclosure relates to the field of communications, and more specifically, to a method for determining frequency domain resources, an electronic device, and a computer program product. Background Technology

[0002] In 5G, the concept of Bandwidth Part (BWP) has been introduced and widely adopted. A BWP is a contiguous segment of frequency domain resources. Downlink, a User Equipment (UE) can be configured with up to five BWPs. The bandwidth of each BWP should be equal to or greater than the bandwidth of the Synchronization Signal Block (SSB), but it may or may not contain an SSB. Only one BWP can be active at any given time, and the UE does not expect to receive the Physical Downlink Shared Channel (PDSCH), Physical Downlink Control Channel (PDCCH), Channel State Information Reference Signal (CSI-RS), or Tracking Reference Signal (TRS) outside of active / activated BWPs. Similarly, uplink, a UE can be configured with up to four BWPs, with only one BWP active / activated at any given time. If the UE is configured with a supplementary uplink, it can also configure up to four carrier bandwidth portions within the supplementary uplink. Only one BWP can be active at any given time, and the UE must not transmit the Physical Uplink Shared Channel (PUSCH) or Physical Uplink Control Channel (PUCCH) outside of the active BWP. Handover can occur between multiple BWPs. Handover can be configured via Radio Resource Control (RRC), time-triggered, or indicated by Downlink Control Information (DCI).

[0003] In related technologies, frequency domain resource switching is achieved through BWP handover. Different BWPs have different frequency domain resources, PDCCH listening timing, maximum number of Multiple-Input Multiple-Output (MIMO) layers, and other configuration parameters. Energy saving can be achieved through BWP handover. For example, switching to a BWP with a smaller bandwidth or a BWP with a smaller maximum number of MIMO layers can save UE power. Existing BWP handover methods include RRC configuration / reconfiguration, time-based BWP handover, and DCI indication. However, BWP handover latency (e.g., 1ms, 0.75ms, 3ms) can prevent rapid BWP handover during data scheduling, impacting data scheduling efficiency and UE energy saving. Summary of the Invention

[0023] The embodiments of this disclosure will be described in detail below with reference to the accompanying drawings and examples.

[0024] It should be noted that the terms "first," "second," etc., in the specification, claims, and drawings of this disclosure are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence.

[0025] In existing 5G wireless access technology communication systems, switching between high and low bandwidth is achieved by configuring multiple Base Stationary Views (BWPs) and the handover between them. However, in 6G research, bandwidth can reach 400MHz, 600MHz, or 800MHz. This ultra-high bandwidth increases UE power consumption and poses challenges to UE implementation. Therefore, how to reduce UE power consumption and improve data transmission efficiency while achieving ultra-high bandwidth is a problem that needs to be solved.

[0026] The methods and embodiments provided in this application can be executed in a mobile terminal, base station, or similar computing device. Taking running on a mobile terminal as an example, Figure 1 This is a hardware structure block diagram of a mobile terminal implementing the frequency domain resource determination method according to an embodiment of this disclosure. Figure 1 As shown, a mobile terminal may include one or more ( Figure 1 Only one is shown in the diagram. A processor 102 (which may include, but is not limited to, a microprocessor MCU or a programmable logic device FPGA, etc.) and a memory 104 for storing data are also shown. The mobile terminal may further include a transmission device 106 for communication functions and an input / output device 108. Those skilled in the art will understand that... Figure 1The structure shown is for illustrative purposes only and does not limit the structure of the mobile terminal described above. For example, the mobile terminal may also include components that are more... Figure 1 The more or fewer components shown, or having the same Figure 1 The different configurations shown.

[0027] The memory 104 can be used to store computer programs, such as application software programs and modules, like the computer program corresponding to the frequency domain resource determination method in this embodiment. The processor 102 executes various functional applications and data processing by running the computer program stored in the memory 104, thereby implementing the above-described method. The memory 104 may include high-speed random access memory and may also include non-volatile memory, such as one or more magnetic storage devices, flash memory, or other non-volatile solid-state memory. In some instances, the memory 104 may further include memory remotely located relative to the processor 102, and these remote memories can be connected to the mobile terminal via a network. Examples of such networks include, but are not limited to, the Internet, corporate intranets, local area networks, mobile communication networks, and combinations thereof.

[0028] The transmission device 106 is used to receive or send data via a network. Specific examples of the network described above may include a wireless network provided by the mobile terminal's communication provider. In one example, the transmission device 106 includes a Network Interface Controller (NIC), which can connect to other network devices via a base station to communicate with the Internet. In another example, the transmission device 106 may be a Radio Frequency (RF) module, used for wireless communication with the Internet.

[0029] This disclosure provides a frequency domain resource determination method that can be executed on the terminal side. Figure 2 This is a flowchart of the frequency domain resource determination method according to an embodiment of this disclosure, as follows: Figure 2 As shown, the process includes the following steps:

[0030] Step S202: Receive configuration signaling, wherein the configuration signaling includes one or more partial bandwidth configurations, one of the partial bandwidth configurations being a first type of partial bandwidth configuration or a second type of partial bandwidth configuration, the first type of partial bandwidth configuration including a first type of parameter set and a second type of parameter set, and the second type of partial bandwidth configuration including a second type of parameter set.

[0031] In this embodiment of the disclosure, the aforementioned partial bandwidth configuration refers to the configuration of partial bandwidth, wherein the partial bandwidth configuration includes a first type of partial bandwidth configuration and a second type of partial bandwidth configuration, and the partial bandwidth includes both the first type of partial bandwidth and the second type of partial bandwidth. The first type of partial bandwidth configuration is a configuration of the first type of partial bandwidth, and the second type of partial bandwidth configuration is a configuration of the second type of partial bandwidth. The above descriptions of the first and second types are merely illustrative and not restrictive. For example, in this embodiment of the disclosure, the partial bandwidth configuration also includes a third type of partial bandwidth configuration.

[0032] In an exemplary embodiment, the first type of parameters in the first type of parameter set are parameters indicated by dynamic scheduling signaling, or parameters indicated by Media Access Control Element (MAC CE) signaling, or parameters configured by higher-layer signaling.

[0033] In one exemplary embodiment, the first type of parameters includes at least one of the following: minimum KO / K2 configuration parameters; KO / K2 Time Domain Resource Allocation (TDRA) table; Connected Discontinuous Reception (CDRX) parameters; Physical Downlink Control Channel (PDCCH) listening behavior configuration parameters; Physical Downlink Control Channel (PDCCH) skipping configuration parameters; Search Space Set Group (SSSG) handover configuration parameters; PDCCH blind detection configuration parameters; maximum multiple-input multiple-output (MIMO) layer; and frequency domain resource bandwidth.

[0034] In the embodiments disclosed herein, the specific contents of the first type of parameters and the second type of parameters are merely illustrative examples. In actual implementation, there may be other contents or types of first type of parameters and second type of parameters related to frequency domain resource configuration, which are not limited here.

[0035] In one exemplary embodiment, the second type of parameters in the second type of parameter set are some bandwidth general parameters or parameters configured by higher-layer signaling.

[0036] In one exemplary embodiment, the second type of parameters includes at least one of the following: subcarrier spacing; frequency domain resource location; frequency domain resource bandwidth; cyclic prefix (CP) type; modulation and coding scheme (MCS) table indication information; and MCS indication information.

[0037] Step S204: Receive the first signaling, which is used to indicate a portion of the bandwidth.

[0038] In this embodiment of the disclosure, the first signaling includes multiple fields, each field indicating parameter indication information of a first type of parameter. Specifically, one of the multiple fields indicates an ID / index for a portion of the bandwidth.

[0039] Figure 3 This is a principle example of the configuration signaling and the first signaling in an embodiment of this disclosure. Figure 1 ,like Figure 3 As shown, the second type of bandwidth in the configuration signaling only configures the second type of parameters, while the first signaling configures the various parameters in the first type of parameter set. For example, various candidate values ​​for the first type of parameters are predefined, and each field of the first signaling indicates one of them. Alternatively, each field of the first signaling indicates the value of a first type of parameter.

[0040] Figure 4 This is a principle example of the configuration signaling and the first signaling in an embodiment of this disclosure. Figure 2 ,like Figure 4 As shown, the second type of bandwidth configuration in the configuration signaling includes a second type of parameters. Each first type parameter in the first type parameter set can be configured with one or more candidate values. The value of each first type parameter is indicated by the first signaling, and the indicated value is one of the candidate values.

[0041] In one exemplary embodiment, in response to a first signaling instruction to activate a first type of partial bandwidth, the byte width of the field indicating the first type of parameter indication information in the second type of partial bandwidth configuration in the first signaling is 0; or, in response to a first signaling instruction to activate a second type of partial bandwidth, the byte width of the field indicating the first type of parameter indication information in the second type of partial bandwidth configuration in the first signaling is greater than or equal to 0.

[0042] In one exemplary embodiment, the first signaling is downlink control information (DCI) signaling or MAC CE signaling.

[0043] In this embodiment of the disclosure, the above examples of the type of the first signaling are merely exemplary descriptions. In actual implementation, the first signaling may also be other forms of instructions.

[0044] In one exemplary embodiment, the first signaling has at least one of the following features: the first signaling is DCI information used to indicate first type parameter indication information in a second type partial bandwidth configuration; the first signaling is non-data scheduling signaling; the first signaling is scrambled by a first Radio Network Temporary Identifier (RNTI), the first RNTI being used to indicate first type parameter indication information in a second type partial bandwidth configuration.

[0045] In this embodiment of the disclosure, the first signaling may be DCI information specifically used to indicate first type parameter indication information in the second type partial bandwidth configuration, or the first signaling may not be used for data scheduling, or the first signaling may be scrambled by a specific RNTI, which is used for first type parameter indication information in the second type partial bandwidth configuration.

[0046] Step S206: Determine the partial bandwidth configuration based on the configuration signaling and the first signaling.

[0047] In one exemplary embodiment, a partial bandwidth configuration is determined based on configuration signaling and a first signaling, the first signaling further including first type parameter indication information in the second type of partial bandwidth configuration, and all parameters of the second type of partial bandwidth configuration are determined based on the configuration signaling and the first signaling.

[0048] In this embodiment of the disclosure, all parameters of the second type of partial bandwidth configuration include first type parameters and second type parameters. The first type parameters are the first type parameters in the first type parameter set indicated by the first type parameter indication information in the first signaling, and the second type parameters are the second type parameters in the second type parameter set included in the second type of partial bandwidth configuration.

[0049] In this embodiment of the disclosure, the second type of partial bandwidth configuration includes not only the second type of parameter set but also the first type of parameter indication information, which is used to indicate the first type of parameter set.

[0050] In this embodiment of the disclosure, the first signaling also includes a second type of partial bandwidth identifier or index indication.

[0051] In one exemplary embodiment, the configuration signaling also includes multiple sets of first-type parameter configurations for second-type partial bandwidth configuration.

[0052] In this embodiment of the disclosure, the second type of partial bandwidth configuration includes not only the second type of parameter set but also multiple sets of first type parameter configurations. The first signaling indicates one of the multiple sets of first type parameter configurations. In actual implementation, this can be achieved by indicating the index or identifier (index / ID) of the corresponding first type parameter configuration.

[0053] Figure 5 This is a principle example of the configuration signaling and the first signaling in an embodiment of this disclosure. Figure 3 ,like Figure 5 As shown, the second type of partial bandwidth configuration includes multiple sets of first type parameter sets. The first signaling indicates the index / ID of the first type parameter set, which corresponds to a configuration of the first type parameter set.

[0054] Figure 6 This is a principle example of the configuration signaling and the first signaling in an embodiment of this disclosure. Figure 4 ,like Figure 6 As shown, the second type of bandwidth configuration includes a second type of parameter set, and each first type parameter in the first type parameter set can be configured with one or more candidate values. The first signaling indicates the first type parameter set index / ID, indicating that the candidate value used for each first type parameter is the indicated index / ID value.

[0055] In one exemplary embodiment, the second type of partial bandwidth configuration includes a set of candidate values ​​for each first type parameter in the first type parameter set, and the first type parameter indication information in the first signaling indicates the value of the first type parameter based on the corresponding set of candidate values.

[0056] In this embodiment of the disclosure, the second type of partial bandwidth configuration may directly include a set of first-type parameters. This set of first-type parameters may be all of the first-type parameters or only a portion of them. Furthermore, multiple different candidate values ​​may be provided for the first-type parameters.

[0057] In one exemplary embodiment, the configuration signaling further includes multiple sets of first-type parameter configurations, the first signaling being used to indicate one set of first-type parameter configurations among the multiple sets of first-type parameter configurations.

[0058] In one exemplary embodiment, the method further includes receiving a second signaling, the second signaling being used to indicate the activation of a first type of partial bandwidth, and the first signaling being used to indicate the activation of a second type of partial bandwidth.

[0059] In one exemplary embodiment, the first signaling and the second signaling satisfy at least one of the following: the first signaling is a first DCI format, the second signaling is a second DCI format, and the first DCI format is different from the second DCI format; the first signaling is non-scheduled data signaling, and the second signaling is data scheduled signaling; the first signaling and the second signaling use different RNTI scrambling; the second signaling is DCI, and the first signaling is MAC CE; the first signaling does not include a field for indicating identification information for a portion of the bandwidth, and the second signaling includes a field for indicating identification information for a portion of the bandwidth.

[0060] Use different signaling types: Type I partial bandwidth or Type II partial bandwidth.

[0061] In one exemplary embodiment, the method further includes: determining a portion of the bandwidth switching delay based on configuration signaling and first signaling.

[0062] In an exemplary embodiment, responding to an instruction to activate a first type of partial bandwidth includes: maintaining the currently activated partial bandwidth if the currently activated partial bandwidth is the first type of partial bandwidth to be activated as indicated; and deactivating the currently activated partial bandwidth and activating the indicated first type of partial bandwidth if the currently activated partial bandwidth is not the first type of partial bandwidth to be activated as indicated, wherein the partial bandwidth switching delay is a preset first delay.

[0063] In one exemplary embodiment, responding to an instruction to activate a second type of partial bandwidth includes: if the currently activated partial bandwidth is the second type of partial bandwidth to be activated, and the first type parameter corresponding to the currently activated second type of partial bandwidth is the same as the first type parameter of the second type of partial bandwidth to be activated, maintaining the currently activated partial bandwidth and all its corresponding parameters; if the currently activated partial bandwidth is the second type of partial bandwidth to be activated, and the first type parameter of the currently activated second type of partial bandwidth is different from the first type parameter of the second type of partial bandwidth to be activated, maintaining the currently activated partial bandwidth, deactivating all first type parameters of the currently activated second type of partial bandwidth, and the first type parameter corresponding to the second type of partial bandwidth to be activated, with a partial bandwidth switching delay of a preset second delay; if the currently activated partial bandwidth is not the second type of partial bandwidth to be activated, deactivating the currently activated partial bandwidth, and the second type of partial bandwidth to be activated, with a partial bandwidth switching delay of a preset first delay.

[0064] In this embodiment of the disclosure, the UE does not expect to receive, upon receiving a partial bandwidth activation signaling message, another signaling message indicating the activation of a second type of partial bandwidth that has already been activated, along with the activated parameters.

[0065] In one exemplary embodiment, the configuration signaling further includes: at least one third-type partial bandwidth configuration, which is associated with a first-type partial bandwidth configuration, and the third-type partial bandwidth configuration includes a first-type parameter set. In this embodiment, the configuration signaling includes a first-type partial bandwidth configuration and at least one third-type partial bandwidth configuration. Each third-type partial bandwidth is associated with a first-type partial bandwidth.

[0066] In some embodiments, the configuration signaling includes a common part bandwidth configuration and at least one third type partial bandwidth configuration. If a third type partial bandwidth configuration is activated and some parameters are missing in the third type partial bandwidth configuration, the parameter values ​​configured in the common part bandwidth configuration can be used. Similarly, the configuration signaling includes a common part bandwidth configuration and at least one second type partial bandwidth configuration. If a second type partial bandwidth configuration is activated and some parameters are missing in the second type partial bandwidth configuration, the parameter values ​​configured in the common part bandwidth configuration can be used. That is, when some parameters are missing in a partial bandwidth configuration, the parameter values ​​configured in the common part bandwidth configuration can be used.

[0067] The first, second, and third types of partial bandwidth are all associated with an index or identifier ID. The partial bandwidth identifier mentioned herein can be understood as a first-type partial bandwidth index or identifier, a second-type partial bandwidth index or identifier, or a third-type partial bandwidth index or identifier. The partial bandwidth identifier can be used to determine whether the indicated / activated portion is a first-type, second-type, or third-type partial bandwidth.

[0068] In one exemplary embodiment, the method further includes: the first signaling is also used to instruct the activation of a third type of partial bandwidth.

[0069] In an exemplary embodiment, responding to an instruction to activate a third type of partial bandwidth includes: when the currently activated partial bandwidth is a third type of partial bandwidth, the currently activated partial bandwidth is different from the third type of partial bandwidth indicated for activation, and the currently activated partial bandwidth is the same as the first partial bandwidth configuration associated with the third type of partial bandwidth indicated for activation, the first type of parameter set in the currently activated partial bandwidth becomes invalid, the first type of parameter set of the third type of partial bandwidth becomes effective, and the partial bandwidth switching delay is a preset second delay; when the currently activated partial bandwidth is a third type of partial bandwidth, and the currently activated partial bandwidth is the same as the third type of partial bandwidth, the currently activated partial bandwidth is maintained; when the currently activated partial bandwidth is a third type of partial bandwidth, the currently activated partial bandwidth is different from the third type of partial bandwidth indicated for activation, and the currently activated partial bandwidth is different from the first partial bandwidth configuration associated with the third type of partial bandwidth indicated for activation, the currently activated partial bandwidth becomes invalid or deactivated, the second type of parameter in the first type of partial bandwidth configuration associated with the third type of partial bandwidth indicated for activation becomes effective, the first type of parameter in the third type of partial bandwidth indicated for activation becomes effective, and the partial bandwidth switching delay is a preset first delay.

[0070] In this embodiment, when the virtual frequency domain resource (e.g., third-type partial bandwidth) is active, if the physical frequency domain resource (non-virtual frequency domain resource, e.g., first-type partial bandwidth) includes parameters configured in the virtual frequency domain resource (e.g., second-type parameters), then the corresponding parameters in the physical frequency domain resource become invalid, while other parameters not configured in the virtual frequency domain resource become active, and the parameters configured in the virtual frequency domain resource (e.g., first-type parameters) become active. In this embodiment, the physical frequency domain resource can correspond to the first-type frequency domain resource configuration in the above embodiments, and the virtual frequency domain resource can correspond to the third-type frequency domain resource configuration in the above embodiments.

[0071] In this embodiment of the disclosure, since the first type of parameter is an energy-saving parameter, that is, the first type of parameter can achieve energy saving by switching its specific value. Therefore, relative to the first type of parameter of the current first type of bandwidth configuration, the alternative first type of parameter can correspond to the aforementioned third type of partial bandwidth configuration, that is, the first type of parameter corresponding to the first type of bandwidth configuration can be switched to the first type of parameter corresponding to the third type of partial bandwidth configuration when needed.

[0072] In this embodiment of the disclosure, there may be multiple first-type parameters, and these multiple first-type parameters constitute a first-type parameter set. Similarly, there may be multiple second-type parameters, and these multiple second-type parameters constitute a second-type parameter set.

[0073] In an exemplary embodiment, the method further includes: when the currently activated partial bandwidth is a third type of partial bandwidth, and the configuration of the first type of partial bandwidth associated with the currently activated third type of partial bandwidth is different from the configuration of the first type of partial bandwidth indicated for activation, deactivating the currently activated third type of partial bandwidth, making the second type of parameter in the configuration of the first type of partial bandwidth associated with the indicated activated third type of partial bandwidth effective, making the first type of parameter of the indicated activated third type of partial bandwidth effective, and the partial bandwidth switching delay is a preset first delay; when the currently activated partial bandwidth is a third type of partial bandwidth, and the configuration of the first type of partial bandwidth associated with the currently activated third type of partial bandwidth is the same as the configuration of the indicated activated first type of partial bandwidth, the first type of parameter of the currently activated third type of partial bandwidth is invalidated, all parameters of the first type of partial bandwidth are effective, and the partial bandwidth switching delay is a preset second delay.

[0074] In one exemplary embodiment, the method further includes: when the currently activated partial bandwidth is a first type of partial bandwidth and the partial bandwidth is the same as the first type of partial bandwidth configuration associated with the indicated activated third type of partial bandwidth, determining that the parameters of the first type of parameter set in the first type of partial bandwidth configuration are invalid, the first type of parameters of the third type of partial bandwidth are effective, and the partial bandwidth switching delay is a preset second delay; when the currently activated partial bandwidth is a first type of partial bandwidth and the partial bandwidth is different from the first type of partial bandwidth configuration associated with the indicated activated third type of partial bandwidth, determining that the currently activated partial bandwidth is invalid or deactivated, the second type of parameters in the first type of partial bandwidth configuration associated with the indicated activated third type of partial bandwidth are effective, the first type of parameters of the third type of partial bandwidth are effective, and the partial bandwidth switching delay is a preset first delay.

[0075] In this embodiment of the disclosure, if the currently activated partial bandwidth is a first type of partial bandwidth and is the same as the first type of partial bandwidth, then the currently activated partial bandwidth is maintained. If the currently activated partial bandwidth is different from the first partial bandwidth, then the currently activated partial bandwidth is deactivated and the first type of partial bandwidth is activated, with the partial bandwidth switching delay being a preset first delay.

[0076] In one exemplary embodiment, the aforementioned preset second delay is less than or equal to the preset first delay.

[0077] In this embodiment of the disclosure, the preset second delay can have different values ​​under different sub-carrier spacings (SCS), and the preset first delay of a portion of the bandwidth can have different values ​​under different SCS. Under the same SCS, the preset second delay is less than or equal to the preset first delay.

[0078] In this embodiment of the disclosure, when partial bandwidth switching only involves switching between first-type parameters, the switching latency is small. If switching between second-type parameters is involved, the switching latency is large.

[0079] In this embodiment of the disclosure, the preset second delay of a portion of the bandwidth BWP is a number greater than or equal to 0. The preset first delay of BWP switching is a number greater than 0. The units are ms or slots.

[0080] In some embodiments, the handover latency value is related to the SCS. In some embodiments, the handover latency value is related to both the SCS and UE capabilities. In some embodiments, the handover latency value is at least related to both the SCS and UE capabilities. In some embodiments, the handover latency value is related to both UE capabilities.

[0081] For example: The preset second delay value is at least one of the following: {0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, ..., 64}. The preset first delay value is at least one of the following: {1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, ..., 24, ..., 128, ... 256}.

[0082] For example: The preset second delay value is at least one of the following: {0, 0.125, 0.25, 0.375, 0.5, 0.625, 0.75, 0.875, 1, ..., 1.5, ..., 2}. The preset first delay value is at least one of the following: {0.125, 0.25, 0.375, 0.5, 0.625, 0.75, 0.875, 1, ..., 2, ..., 4}.

[0083] For example: the preset second delay value is at least K1 times the minimum slot length in the 6G system. The preset first delay value is at least K2 times the minimum slot length in the 6G system. K1 is an integer greater than or equal to 0. K2 is an integer greater than 0. Table 1 is a comparison table of handover delay and UE capability. As shown in Table 1, in some embodiments, K1 and K2 are both sets of multiple values. Each value corresponds to a SCS. The maximum value in K1 is less than the maximum value in K2.

[0085]

[0086] For example, BWP handover delay A is a preset second delay, and BWP handover delay B is a preset first delay.

[0087] In one exemplary embodiment, the method further includes: receiving third signaling, the third signaling indicating one or more second-class partial bandwidths or third-class partial bandwidths, the first signaling indicating one of the one or more second-class partial bandwidths or the first signaling indicating one of the one or more third-class partial bandwidths or third-class partial bandwidths.

[0088] In an exemplary embodiment, when the third signaling is used to indicate one or more second-type partial bandwidths or third-type partial bandwidths, one or more second-type partial bandwidths or third-type partial bandwidths are selected as candidate activated or triggered partial bandwidths.

[0089] In an exemplary embodiment, when the first signaling is used to indicate one of one or more second-type partial bandwidths, or when the first signaling indicates one of one or more third-type partial bandwidths, the indicated second-type partial bandwidth or the indicated third-type partial bandwidth is used as the activated or triggered partial bandwidth.

[0090] In one exemplary embodiment, the third signaling is MAC CE signaling, and the first signaling is DCI signaling.

[0091] This disclosure also provides a frequency domain resource determination method, which can be executed on the base station side. Figure 7 This is another flowchart of the frequency domain resource determination method according to an embodiment of the present disclosure, such as... Figure 7 As shown, the process includes the following steps:

[0092] Step S702: Send configuration signaling, wherein the configuration signaling includes one or more partial bandwidth configurations, one of the partial bandwidth configurations being a first type of partial bandwidth configuration or a second type of partial bandwidth configuration, the first type of partial bandwidth configuration including a first type of parameter set and a second type of parameter set, and the second type of partial bandwidth configuration including a second type of parameter set.

[0093] In this embodiment of the disclosure, the aforementioned partial bandwidth configuration refers to the configuration of partial bandwidth, wherein the partial bandwidth configuration includes a first type of partial bandwidth configuration and a second type of partial bandwidth configuration, and the partial bandwidth includes both the first type of partial bandwidth and the second type of partial bandwidth. The first type of partial bandwidth configuration is a configuration of the first type of partial bandwidth, and the second type of partial bandwidth configuration is a configuration of the second type of partial bandwidth. The above descriptions of the first and second types are merely illustrative and not restrictive. For example, in this embodiment of the disclosure, the partial bandwidth configuration also includes a third type of partial bandwidth configuration.

[0094] Step S704: Send a first signaling message, which is used to indicate a partial bandwidth, so as to instruct the terminal to determine the partial bandwidth configuration based on the configuration signaling message and the first signaling message.

[0095] In one exemplary embodiment, the frequency domain resource determination method further includes: sending a second signaling message, the second signaling message being used to indicate the activation of a first type of partial bandwidth, and the first signaling message being used to indicate the activation of a second type of partial bandwidth.

[0096] In one exemplary embodiment, the first signaling and the second signaling satisfy at least one of the following: the first signaling is a first DCI format, the second signaling is a second DCI format, and the first DCI format is different from the second DCI format; the first signaling is non-scheduled data signaling, and the second signaling is data scheduled signaling; the first signaling and the second signaling use different RNTI scrambling; the second signaling is DCI, and the first signaling is MAC CE; the first signaling does not include a field for indicating identification information for a portion of the bandwidth, and the second signaling includes a field for indicating identification information for a portion of the bandwidth.

[0097] In one exemplary embodiment, the frequency domain resource determination method further includes: sending a third signaling, the third signaling indicating one or more second-class partial bandwidths or third-class partial bandwidths, the first signaling indicating one of the one or more second-class partial bandwidths, or the first signaling indicating one of the one or more third-class partial bandwidths, a third-class partial bandwidth.

[0098] In an exemplary embodiment, when the third signaling is used to indicate one or more second-type partial bandwidths or third-type partial bandwidths, one or more second-type partial bandwidths or third-type partial bandwidths are selected as candidate activated or triggered partial bandwidths.

[0099] In one exemplary embodiment, the third signaling is MAC CE signaling, and the first signaling is DCI signaling.

[0100] In this embodiment of the disclosure, the features of the first signaling, the second signaling, and the third signaling involved in the steps of the base station executing the frequency domain resource determination method can be referred to the specific content of the steps of the terminal executing the frequency domain resource determination method, which will not be repeated here.

[0117] To enable those skilled in the art to better understand the technical solutions disclosed herein, the following description is provided in conjunction with different embodiments.

[0118] Example 1

[0119] Figure 9 Example of the principle of the frequency domain resource determination method in this disclosure Figure 1 ,like Figure 9 As shown, it includes the following steps:

[0120] Step S901: The base station configures a frequency domain resource group or pair for the UE.

[0121] In this embodiment, the base station configures frequency domain resource groups or pairs for the UE by sending configuration signaling to the UE.

[0122] In this embodiment, the base station configures multiple frequency domain resource groups for the UE, and each frequency domain resource group contains M sets of frequency domain resources. The frequency domain resource groups correspond to multiple partial bandwidth configurations in the above embodiments, and the frequency domain resources correspond to a partial bandwidth in the above embodiments. The partial bandwidth configuration may include a first type of parameter set and / or a second type of parameter set.

[0123] In actual implementation, multiple partial bandwidth configurations include a first type of partial bandwidth configuration and a second type of partial bandwidth configuration. The first type of partial bandwidth configuration includes a first type of parameter set and a second type of parameter set, and the second type of partial bandwidth configuration includes a second type of parameter set.

[0124] In some embodiments, the plurality of partial bandwidth configurations include a first type of partial bandwidth configuration and a third type of partial bandwidth configuration, wherein the first type of partial bandwidth configuration includes a first type of parameter set and a second type of parameter set, and the third type of partial bandwidth configuration includes the first type of parameter set. The third type of portion in the frequency domain value resource group is associated with the first type of portion.

[0125] In some embodiments, a frequency domain resource group includes multiple first-type partial bandwidth configurations, and the second-type parameter sets of these multiple first-type partial bandwidth configurations are identical, meaning that the values ​​of the second-type parameters in the second-type parameter sets are the same. In other words, the multiple first-type partial bandwidth configurations within the frequency domain resource group differ only in the configuration of their first-type parameter sets. Switching a portion of the bandwidth within the frequency domain resource group is equivalent to switching the first-type parameter set. Therefore, its latency is lower than the latency of switching all parameters of a partial bandwidth.

[0126] In this embodiment, the second type of parameters includes at least one of the following: subcarrier spacing; frequency domain resource location; frequency domain resource bandwidth; CP type; MCS table indication information.

[0127] In this embodiment, the first type of parameters includes at least one of the following: Search space set configuration; Control resource set (CORESET) configuration; TDRA table configuration; Minimum K0 / K2 configuration; PDCCH skipping configuration; SSSG handover configuration; Channel State Information-Reference Signal (CSI-RS) configuration; Channel State Information (CSI) reporting configuration; PDCCH blind detection configuration; Parameters of the maximum MIMO layer; Frequency domain resource bandwidth; PDCCH listening behavior configuration; CDRX configuration; Wake-Up Signal (WUS) configuration; Paging Advance Indicator (PEI) information; TRS information.

[0128] In this embodiment, the search spaces for different frequency domain resource configurations are different; for example, the period and duration are different, resulting in different power consumption when switching to different frequency domain resources. Similarly, the CORESETs for different frequency domain resource configurations are different; for example, the number of resource blocks (RBs) and the number of Orthogonal Frequency Division Multiplexing (OFDM) symbols in a CORESET are different, resulting in different power consumption when switching to different CORESETs (i.e., switching to different frequency domain resources).

[0129] In this embodiment, the UE's power consumption varies depending on the configuration of these parameters (e.g., the first type of parameters). Energy saving can be achieved by switching the first type of parameters. For example, a search space set with a longer period saves more power than one with a shorter period. Having the same second type of parameters for different frequency domain resources reduces the number of parameters that need to be changed when switching between different frequency domain resources, thereby improving frequency domain resource switching efficiency and reducing switching time. For example, the switching delay for frequency domain resource switching within a frequency domain resource group is less than or equal to one slot. Alternatively, the switching delay for frequency domain resource switching within a frequency domain resource group is a preset second switching delay.

[0130] In this embodiment, all parameters must be configured for each frequency domain resource, i.e., each partial bandwidth configuration. Each partial bandwidth corresponds to an index / ID. The switching / activation of the partial bandwidth is indicated by the corresponding index / ID through the first signaling (e.g., DCI), thereby realizing the switching of frequency domain resources and achieving the purpose of switching the first type of parameters.

[0131] It should be noted that in some embodiments, within the same partial bandwidth group (frequency domain resource group) configuration, there may be only one or two different first-type parameters, or there may be multiple different first-type parameters. For example, a partial bandwidth group configuration may contain M frequency domain resources, where frequency domain resource 1 and frequency domain resource 2 differ only in their configured search space sets, frequency domain resource 1 and frequency domain resource 3 differ only in their configured skip PDCCH related parameters, frequency domain resource 3 and frequency domain resource 4 differ in their configured minimum K0, K2, and TDRA lists, and frequency domain resource 4 differs from frequency domain resource 1 in their configured minimum K0, K2, TDRA lists, and search space settings.

[0132] In some embodiments, the base station configures multiple BWPs (Frequency Domain Resources) for the UE, each BWP corresponding to a BWP ID, including a BWP group and BWPs not in the BWP group. BWPs within a BWP group differ only in their second type of parameter configuration. A first signaling instruction (e.g., DCI) indicates a BWP ID, signifying the activation of the BWP corresponding to that BWP ID and the deactivation of the currently active BWP. The activated BWP is activated after a preset handover delay.

[0133] When the first signaling indicates that the activated BWP is a BWP within a BWP group, if the currently activated BWP is a BWP within a BWP group and the currently activated BWP is different from the indicated activated BWP, then the preset switching delay is the second preset delay.

[0134] When the first signaling indicates that the activated BWP is a BWP within a BWP group, if the currently activated BWP is a BWP within a BWP group and the currently activated BWP is different from the indicated activated BWP, then no BWP handover will be performed.

[0135] When the first signaling indicates that the activated BWP is a BWP within a BWP group, if the currently activated BWP is not a BWP within the BWP group corresponding to the activated BWP, the preset switching delay is the first preset delay.

[0136] When the first signaling indicates that the activated BWP does not belong to a BWP group, the preset handover delay is the first preset delay.

[0137] Example 2

[0138] Figure 10 Example of the principle of the frequency domain resource determination method in this disclosure Figure 2 ,like Figure 10 As shown, it includes the following steps:

[0139] In step S1001, the base station configures one physical frequency domain resource configuration and multiple associated virtual frequency domain resources for the UE.

[0140] In this embodiment, the aforementioned physical frequency domain resources can correspond to the first type of frequency domain resource configuration in the above embodiments, and the aforementioned virtual frequency domain resources can correspond to the third type of frequency domain resource configuration in the above embodiments. The first type of parameter in the third type of frequency domain resource configuration is the energy-saving parameter.

[0141] In this embodiment, the base station can configure one physical frequency domain resource configuration and multiple associated virtual frequency domain resources for the UE via configuration instructions. The physical frequency domain resource configuration (first type of frequency domain resource configuration) configures all parameters, while the other virtual frequency domain resource configurations (third type of frequency domain resource configuration) only include some parameters and are associated with the physical frequency domain resource configuration. Other parameters not configured in the virtual frequency domain resource configurations use the corresponding parameters configured in the physical frequency domain configuration. For example, some virtual frequency domain resource configurations only include TDRA table configuration, and some only include search space setting configuration. Which frequency domain resource configuration is enabled is determined according to signaling instructions.

[0142] In some embodiments, the base station can configure one common frequency domain resource configuration and multiple virtual frequency domain resources for the UE via configuration instructions. The common frequency domain resource configuration configures some parameters, while the additional virtual frequency domain resource configurations (the third type of frequency domain resource configuration) only include some of the first type of parameters. Other parameters not configured in the virtual frequency domain resource configurations use the corresponding parameters configured in the common frequency domain configuration. For example, some virtual frequency domain resource configurations only include TDRA table configuration, and some only include search space setting configuration. The enabled frequency domain resource configuration is determined according to signaling instructions.

[0143] In this embodiment, among the M sets of frequency domain resource configurations in a frequency domain resource configuration group, only some parameters may be configured in the M-1 sets of frequency domain resource configurations (virtual frequency domain resource configurations), while other parameters may not be configured.

[0144] In this embodiment, the first frequency domain resource configuration and the second frequency domain resource configuration in the M-1 set of frequency domain resource configurations are associated. The first frequency domain resource configuration is the third type of partial bandwidth configuration in the above embodiments, and the second frequency domain resource configuration is the first type of partial bandwidth configuration in the above embodiments. The second frequency domain resource configuration associated with the first frequency domain resource configuration contains configurations for parameters not configured in the first frequency domain resource configuration. Alternatively, the second frequency domain resource configuration associated with the first frequency domain resource configuration contains all configuration parameters.

[0145] In this embodiment, parameters not configured in the first frequency domain resource configuration are configured using the corresponding parameters in the associated second frequency domain resource configuration.

[0146] In this embodiment, the parameters configured in different first frequency domain resource configurations can be different.

[0147] In this embodiment, different first frequency domain resource configurations can be associated with different second frequency domain resource configurations.

[0148] In some embodiments, different first frequency domain resource configurations are associated with the same second frequency domain resource configuration. The advantage of this setup is that fewer parameters need to be configured; only the parameters that need to be changed need to be configured. Having the same parameters across different frequency domain resources reduces handover latency.

[0149] In this embodiment, associated frequency domain resources can form frequency domain resource groups. Each frequency domain resource corresponds to an index / ID. A first signaling instruction (e.g., DCI) instructs the corresponding index / ID to indicate frequency domain resource switching within the frequency domain resource group. The parameters configured for the frequency domain resource indicated by the first signaling instruction take effect. For example, in a frequency domain resource group, frequency domain resource 1 is configured with all parameters, frequency domain resource 2 is configured with only the maximum MIMO layer parameter, and the configured maximum MIMO layer parameter value is different from that configured in frequency domain resource 1. Frequency domain resource 3 is configured with minimum K0 and K2 values, as well as SSSG handover-related parameters. When the first signaling instruction instructs frequency domain resource 1, the parameters configured in frequency domain resource 1 take effect. When the first signaling instruction instructs frequency domain resource 2, all parameters in frequency domain resource 1 except for the maximum MIMO layer parameter take effect, and the maximum MIMO layer parameter takes effect according to the parameters configured in frequency domain resource 2. When the first signaling instruction instructs frequency domain resource 3, all parameters in frequency domain resource 1 except for those configured in frequency domain resource 3 take effect, and the parameters in frequency domain resource 3 take effect.

[0150] In other words, when a virtual frequency domain resource (one of M-1) is active, if the physical frequency domain resource (non-virtual frequency domain resource) includes the parameters configured in the virtual frequency domain resource, then the corresponding parameters in the physical frequency domain resource become invalid, and other parameters not configured in the virtual frequency domain resource become effective. In addition, the parameters configured in the virtual frequency domain resource become effective.

[0151] Each frequency domain resource corresponds to an index / ID. The first signaling instruction indicates a frequency domain resource index / ID, signifying the indication / activation of its corresponding frequency domain resource. The indicated or activated frequency domain resource takes effect / activates after a predefined handover delay. Specifically,

[0152] When the currently active frequency domain resource is a virtual frequency domain resource, if the indicated frequency domain resource is another virtual frequency domain resource and the physical frequency domain resources associated with the two virtual frequency domain resources are the same, the indicated frequency domain resource will take effect after the second handover delay.

[0153] When the currently active frequency domain resource is a virtual frequency domain resource, if the indicated frequency domain resource is another virtual frequency domain resource and the physical frequency domain resources associated with the two virtual frequency domain resources are different, the indicated frequency domain resource will take effect after the first handover delay.

[0154] If the currently active frequency domain resource is a virtual frequency domain resource, then no switching is required when the indicated frequency domain resource is the currently active virtual frequency domain resource.

[0155] If the currently active frequency domain resource is a physical frequency domain resource, and the indicated frequency domain resource is a virtual frequency domain resource, and the physical frequency domain resource associated with the indicated active virtual frequency domain resource is the currently active frequency domain resource, then the indicated frequency domain resource will take effect after the second handover delay.

[0156] If the currently activated frequency domain resource is a physical frequency domain resource, and the indicated frequency domain resource is a virtual frequency domain resource, and the physical frequency domain resource associated with the indicated activated virtual frequency domain resource is different from the currently activated frequency domain resource, then the indicated frequency domain resource will take effect after the first handover delay.

[0157] If the currently active frequency domain resource is a physical frequency domain resource, and the indicated frequency domain resource is a physical frequency domain resource, and the two physical frequency domain resources are different, then the indicated frequency domain resource will take effect after the first handover delay.

[0158] If the currently active frequency domain resource is a physical frequency domain resource, and the indicated frequency domain resource is a physical frequency domain resource, and the two physical frequency domain resources are the same, then no switching is required.

[0159] Example 3

[0160] Figure 11 Example of the principle of the frequency domain resource determination method in this disclosure Figure 3 ,like Figure 11 As shown, it includes the following steps:

[0161] Step S1101: The base station configures a semi-dynamic frequency domain resource type (e.g., second type partial bandwidth configuration) for the UE.

[0162] In this embodiment, the base station can configure a semi-dynamic frequency domain resource type for the UE through configuration instructions.

[0163] In this embodiment, the semi-dynamic frequency domain resource type refers to the frequency domain resource type whose parameters are configured by RRC. Some parameters (second type parameters) are configured in only one set, while some parameters (first type parameters) can be configured in multiple sets. For first type parameters configured in multiple sets, each set is associated with an index / ID, and the first signaling (e.g., DCI) can indicate which set of second type parameters is in effect. After the DCI indication, the configured parameters remain in effect until new indication information, RRC reconfiguration information, or frequency domain resource switching information is received.

[0164] In other words, in this embodiment, some parameters of the semi-dynamic frequency domain resource type are statically configured, i.e., configured by RRC, while some parameters are dynamically indicated, i.e., indicated by DCI. The advantage of this setting is that it reduces the number of configured parameters and enables rapid switching between the second type of parameters.

[0165] In this embodiment, at least two types of frequency domain resources can be configured: a first type of static frequency domain resource configuration (e.g., a first type of partial bandwidth) and a second type of semi-dynamic frequency domain resource configuration (e.g., a second type of partial bandwidth). The first type of static frequency domain resource configuration refers to all parameters of the frequency domain resource being configured by RRC. The second type of semi-dynamic frequency domain resource configuration involves some parameters being configured by RRC and others being indicated by DCI. For example, multiple values ​​can be configured, and the DCI indicates one of them; or multiple values ​​can be predefined, and the DCI indicates one of them. The second type of semi-dynamic frequency domain resource configuration can be activated and deactivated via DCI indication. When the DCI indication is activated, the relevant parameters must be indicated simultaneously.

[0166] In one embodiment, when a semi-dynamic frequency domain resource is activated, the semi-dynamic frequency domain resource cannot be activated again, even if other parameter values ​​are indicated in the DCI indicating reactivation.

[0167] In one embodiment, when a semi-dynamic frequency domain resource is activated, the semi-dynamic frequency domain resource can be reactivated, and the parameter value indicated by the DCI indicating reactivation needs to be different from the parameter value indicated in the previously activated DCI.

[0168] In one embodiment, the DCI can instruct the activation and / or reconfiguration and / or deactivation and / or initialization of semi-dynamic frequency domain resources, wherein different DCI types are as follows:

[0169] Activate DCI: Activate semi-dynamic frequency domain resources and carry some parameter value indication information.

[0170] DCI reconfiguration: Maintains semi-dynamic frequency domain resources and carries reconfiguration information for some parameters.

[0171] Deactivate DCI: Deactivate semi-dynamic frequency domain resources.

[0172] Initialize DCI: Activate the semi-dynamic frequency domain resource, and set all or some of its parameters to predefined or default values.

[0173] In one embodiment, activation and / or deactivation of semi-dynamic frequency domain resources is indicated by MAC CE signaling, and reconfiguration and / or initialization of semi-dynamic frequency domain resources is indicated by DCI signaling.

[0174] In some embodiments, the switching delay required for parameter switching of the same semi-dynamic frequency domain resource is a preset second switching delay, meaning the parameters of the indicated semi-dynamic frequency domain resource take effect after the preset second switching delay; the switching delay required for switching between different semi-dynamic frequency domain resources is a preset first switching delay, meaning the indicated semi-dynamic frequency domain resource takes effect after the preset first switching delay; the switching delay required for switching between a semi-dynamic frequency domain resource and a static frequency domain resource (switching from a semi-dynamic frequency domain resource to a static frequency domain resource, or vice versa) is a preset first switching delay, meaning the indicated semi-dynamic frequency domain resource or static frequency domain resource takes effect after the preset first switching delay. The first switching delay is greater than or equal to the second switching delay.

[0175] Example 4

[0176] In this embodiment, the base station is configured with a second type of partial bandwidth configuration, in which a second type of parameter set is configured through higher-layer signaling.

[0177] In one embodiment, the second type of partial bandwidth configuration includes multiple sets of first type parameter sets configured via higher-layer signaling.

[0178] The first signaling instruction indicates one of multiple sets of first-class parameter sets. Optionally, one set of first-class parameter sets in the second-class partial bandwidth configuration is the default first-class parameter set activated, that is, when the second-class partial bandwidth configuration is activated, the first-class parameter set is used by default before receiving the signaling instruction.

[0179] In this embodiment of the disclosure, the first set of first-class parameters can be activated by default. Alternatively, a predefined set of first-class parameters can be activated by default.

[0180] In one embodiment, the second type of partial bandwidth configuration is configured with a first type of parameter set via higher-layer signaling, wherein each first type of parameter is configured with one or more candidate values.

[0181] In one embodiment, the first signaling indicates one of one or more candidate values ​​in each first type of parameter.

[0182] In actual implementation, the first signaling may contain multiple fields, each indicating a value in a first type of parameter.

[0183] For example, if the first field corresponds to the first type of parameter #1 and the first field indicates 'i', then it indicates the (i+1)th value configured in the first type of parameter #1. 'i' is a number greater than or equal to 0. If the second field corresponds to the first type of parameter #2 and the second field indicates 'j', then it indicates the (j+1)th value configured in the first type of parameter #2. 'j' is a number greater than or equal to 0.

[0184] In actual implementation, the bit width of each field is determined by the number of candidate values ​​configured for its corresponding first-type parameter.

[0185] In actual implementation, it can be a field in the first signaling, indicating the values ​​of all first-class parameters.

[0186] For example, if the field indicates 'i', it represents the (i+1)th value of all first-class parameters. If the number of candidate values ​​for a first-class parameter is less than 'i+1', it represents the predefined candidate value or the last candidate value for that first-class parameter.

[0187] In actual implementation, the bit width of this field is determined by the number of parameters configured with the most or fewest candidate values ​​in the first type of parameter set.

[0188] In one embodiment, the second type of partial bandwidth configuration has a first type of parameter set that is activated by default. That is, when the second type of partial bandwidth configuration is activated, the first type of parameter set is used by default before receiving a signaling instruction.

[0189] In this embodiment of the disclosure, the first set of parameters of the first configuration can be activated by default. The first set of parameters of the first configuration can be activated by default.

[0190] In one embodiment, the second type of partial bandwidth configuration only includes the second type of parameter set.

[0191] In one embodiment, the first signaling indicates parameters in a first set of parameters.

[0192] For example, candidate values ​​for the first type of parameter are predefined in the first type of parameter set, and the first signaling indicates the first type of parameter.

[0193] For example, the first signaling indicates the value of each of the first type of parameters in the first type of parameters.

[0194] In one embodiment, optionally, a set of first-type parameter sets is used as the default active first-type parameter set in the second type partial bandwidth configuration. That is, when the second type partial bandwidth configuration is activated, the first-type parameter set is used by default before receiving a signaling instruction.

[0195] In this embodiment of the disclosure, the first set of parameters of the first configuration can be activated by default. Alternatively, a predefined set of parameters of the first type can be activated by default.

[0196] In one embodiment, the first signaling is MAC CE signaling or higher-layer signaling (e.g., DCI). The advantage of this approach is that, compared to switching all parameters in a partial bandwidth BWP, switching the first set of parameters in a second type of partial bandwidth configuration via the first signaling allows for faster switching. Generally speaking, for the second type of partial bandwidth configuration, where higher-layer signaling configures some parameters, the first signaling indicates the other set of parameters. Furthermore, the first signaling can indicate the switching of the values ​​of the other set of parameters. When both the first and second types of partial bandwidth configurations exist simultaneously, the partial bandwidth BWP switching can have the following possibilities:

[0197] (1) Switching between the first type of partial bandwidth configurations;

[0198] (2) Switching between Category I partial bandwidth configuration and Category II partial bandwidth configuration;

[0199] (3) Switching between the second type of bandwidth configurations;

[0200] (4) Switching of first-class parameters within the same second-class partial bandwidth configuration.

[0201] For cases (1), (2), and (3) above, the switching of the second type of parameters may be involved, therefore the switching time is relatively long. For case (4) above, only the switching of some parameters is involved, therefore the switching time is short. For cases (1), (2), (3), and (4) above, the same signaling may be used for indication.

[0202] In actual implementation, the signaling indicating the first type of partial bandwidth configuration (second signaling) may differ from the signaling indicating the second type of partial bandwidth configuration (first signaling). This is because indicating the first type of partial bandwidth configuration does not require indicating the content of the first type of parameters, while indicating the second type of partial bandwidth configuration requires indicating the content of the first type of parameters.

[0203] In one embodiment, when indicating a second type of partial bandwidth configuration, it is necessary to first pre-activate the second type of partial bandwidth configuration using one signaling, and then indicate the first type of parameter in the second type of partial bandwidth configuration using another signaling. In one embodiment, a fourth signaling can be used to indicate the partial bandwidth BWPID (which can indicate either the first type of partial bandwidth configuration or the second type of partial bandwidth configuration). If the indicated partial bandwidth configuration is the second type, the first signaling can then be used to indicate the value of the first type of parameter in the second type of partial bandwidth configuration. The first signaling may not include partial bandwidth identification information. The fourth signaling is DCI or MAC CE, and the first signaling is DCI. In one embodiment, a field in the first signaling can be used to indicate the partial bandwidth BWPID. Based on the indication content of this indication field, it is determined whether there is a field in the first signaling indicating the first type of parameter. In one embodiment, a third signaling can be used to indicate the first type of partial bandwidth configuration ID. The second signaling is used to indicate the partial bandwidth BWP ID of the second signaling, and then the first signaling is used to indicate the value of the first type of parameter in the second type of partial bandwidth configuration. The third signaling is DCI, the second signaling is DCI or MAC CE, and the first signaling is DCI. Optionally, a fourth signaling may be used to indicate one or more pre-activated Type II partial bandwidth configurations, and a first signaling may be used to indicate one of the Type II partial bandwidth configurations and its Type I parameter value. In one embodiment, a fourth signaling may be used to indicate one or more pre-activated Type II partial bandwidth configurations, a second signaling may be used to indicate the partial bandwidth BWP ID of the second signaling, and a first signaling may be used to indicate the Type I parameter value in the Type II partial bandwidth configuration. The fourth signaling is MAC CE signaling. Optionally, a fourth signaling may be used to indicate one or more pre-activated Type II partial bandwidth configurations or Type I partial bandwidth configurations, and a first signaling may be used to indicate one of the Type II partial bandwidth configurations and its Type I parameter value, or to indicate a Type I partial bandwidth configuration. Optionally, a fourth signaling may be used to indicate one or more pre-activated partial bandwidths (e.g., Type I partial bandwidth, and / or Type II partial bandwidth, and / or Type III partial bandwidth), and a first signaling may be used to indicate a partial bandwidth of the pre-activated partial bandwidths.

[0204] In one embodiment, the switching between various partial bandwidth BWPs or between partial bandwidth BWP parameters can be signaled or triggered by a first condition, the specific content of which is not limited here.

[0205] In actual implementation, the first condition can be at least one of the following: receiving data scheduling, timer expiration, receiving signaling indication, CDRX status change, cell discontinuous transmission or discontinuous reception (Cell Discontinuous Transmission / Cell Discontinuous Reception, Cell DTX / DRX) status change.

[0206] For example, a third-type BWP switches to its associated first-type BWP after receiving a data schedule. Alternatively, a third-type BWP switches to its associated first-type BWP after receiving a data schedule exceeding a first threshold. In some embodiments, switching to a first-type BWP triggers a timer startup / restart, and the first-type BWP switches to an associated third-type BWP after the timer expires. The third-type BWP can be a predefined third-type BWP or a third-type BWP indicated by signaling.

[0207] For example, during CDRX active time, the system switches to a first-type BWP, and during CDRX off time, it switches to a second-type or third-type BWP. The third-type BWP can be a predefined third-type BWP or a third-type BWP indicated by signaling. Similarly, the second-type BWP can be a predefined second-type BWP or a second-type BWP indicated by signaling.

[0208] For example, during the Cell DTX / DRX active time, the system switches to a Type 1 BWP; when the Cell DTX / DRX goes off, it switches to a Type 2 or Type 3 BWP. The Type 3 BWP can be a predefined Type 3 BWP or a Type 3 BWP indicated by signaling. Similarly, the Type 2 BWP can be a predefined Type 2 BWP or a Type 2 BWP indicated by signaling.

[0209] For example, the first BWP switches to the second BWP after receiving a data schedule. Alternatively, the first BWP switches to the second BWP after receiving a data schedule greater than a first threshold. "Greater than the first threshold" means the data packet size exceeds the first threshold. In some embodiments, switching to the second BWP triggers a timer start / restart; after the timer expires, the second BWP switches back to the first BWP. The first BWP can be predefined or indicated by signaling. The first BWP and the second BWP can be BWPs from the same BWP group, or they can be BWPs of different types.

[0210] For example, during CDRX active time, the system switches to the first BWP, and during CDRX off time, it switches to the second BWP. The second BWP can be a predefined third-type BWP, or a third-type BWP indicated by signaling. The second BWP can also be a predefined second-type BWP, or a second-type BWP indicated by signaling.

[0211] For example, during the Cell DTX / DRX active time, the system switches to the first BWP, and when the Cell DTX / DRX goes off, it switches to the second BWP. The second BWP can be a predefined third-type BWP, or a third-type BWP indicated by signaling. Alternatively, the second BWP can be a predefined second-type BWP, or a second-type BWP indicated by signaling.

[0212] For example, during CDRX active time, the system switches to the first BWP, and during CDRX OFR, it switches to the second BWP. The first BWP can be a predefined third-type BWP, or a third-type BWP indicated by signaling. The second BWP can be a predefined second-type BWP, or a second-type BWP indicated by signaling.

[0213] For example, during the Cell DTX / DRX active time, the system switches to the first BWP, and when the Cell DTX / DRX enters an OFR state, it switches to the second BWP. The first BWP can be a predefined third-type BWP, or a third-type BWP indicated by signaling. The second BWP can be a predefined second-type BWP, or a second-type BWP indicated by signaling.

[0214] It should be noted that, as described in this disclosure, indicating a partial bandwidth BWP ID means switching to the indicated partial bandwidth BWP. Alternatively, indicating a partial bandwidth BWP ID means switching the active partial bandwidth BWP to the indicated partial bandwidth BWP. Deactivating a partial bandwidth BWP means switching from that partial bandwidth BWP to another partial bandwidth BWP. The parameters indicating a BWP refer to the parameters for switching the partial bandwidth BWP. Or, the parameters indicating a partial bandwidth BWP refer to the parameters for switching / updating the partial bandwidth BWP.

[0215] In one embodiment, if the second type of partial bandwidth configuration is activated, when the first timer expires, the parameters in the second type of partial bandwidth configuration use default parameters. When the second timer expires, it switches to the default partial bandwidth BWP. In one embodiment, the first timer is less than the second timer.

[0216] In some embodiments, the configuration signaling includes multiple BWP configurations, such as a first type BWP, a second type BWP, and a third type BWP. The first type BWP is configured with a first type of parameters, a first set of parameters for the second type of parameters, and a second set of parameters for the second type of parameters. The second type BWP is configured with the first type of parameters and the first set of parameters for the second type of parameters. The third type BWP is configured with the first type of parameters. The first type of parameters, the first set of parameters for the second type of parameters, and the second set of parameters for the second type of parameters together constitute all the parameters of a BWP. The specific parameters within the first type of parameters, the first set of parameters for the second type of parameters, and the second set of parameters for the second type of parameters are not limited.

[0217] Therefore, when switching between BWPs of the first type, the switching delay is the predefined first switching delay;

[0218] When switching between BWPs of the second type, the switching delay is the predefined second switching delay;

[0219] When switching between third-class BWPs, the switching delay is the predefined third switching delay;

[0220] When switching between different types of BWPs, the switching delay is a predefined first switching delay.

[0221] The predefined first handover delay is greater than or equal to the predefined second handover delay. The predefined second handover delay is greater than or equal to the predefined third handover delay.

[0222] The predefined first handover delay, predefined second handover delay, and predefined third handover delay are related to the SCS and / or UE capabilities.

[0223] In other words, different switching delays are applied based on the number and / or types of parameter values ​​that are changed / updated when switching BWPs. The number and / or types of parameters can be predefined into two, three, four, or more types, and correspondingly, the types of switching delays will also increase.

[0224] Frequency domain resources can be BWP, carrier / carrier, or cell.

[0225] The above description is merely a preferred embodiment of this disclosure and is not intended to limit this disclosure. Various modifications and variations can be made to this disclosure by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the principles of this disclosure should be included within the scope of protection of this disclosure.
