Description

Technical Field

[0001] The present application relates to the field of communication technology, and in particular to a method, device, electronic device, and storage medium for configuring a subset bandwidth (BWP). Background Art

[0002] In 5G NR (New Radio), multiple dedicated BWPs (Bandwidth parts) can be configured for a terminal.

[0003] Currently, if a terminal supports multiple BWP configurations, two BWPs are usually configured for the terminal, including a wideband BWP and a narrowband BWP.

[0004] When the terminal schedules a small amount of data, it can work on a narrowband BWP; when the terminal schedules a large amount of data, it needs to work on a wideband BWP. The larger the working bandwidth, the higher the sampling rate and the higher the power consumption.

[0005] It can be seen that by adaptively adjusting the bandwidth used by the terminal for receiving and sending, the goal of terminal energy saving can be achieved.

[0006] However, the terminal energy saving effect that can be achieved by only switching between broadband BWP and narrowband BWP is limited. Summary of the Invention

[0050] Beneficial effects of the embodiments of the present application:

[0051] The configuration method, device, electronic device and storage medium of the subset bandwidth BWP provided in the embodiments of the present application are applied to detect whether the target terminal accessing the base station supports multi-BWP configuration. If supported, the broadband BWP resources and narrowband BWP resources to be allocated are determined for the target terminal; the discontinuous reception DRX cycle for the target terminal is determined; and it is judged whether the narrowband BWP resources conflict with the DRX cycle. If not, the broadband BWP is configured for the target terminal based on the determined broadband BWP resources, the narrowband BWP is configured for the target terminal based on the determined narrowband BWP resources, and the DRX is configured for the target terminal based on the determined DRX cycle.

When it is judged that the narrowband BWP resource does not conflict with the DRX cycle, the target terminal can be configured with broadband BWP, narrowband BWP and DRX at the same time. The broadband BWP and narrowband BWP share the same DRX cycle, so that the target terminal can save energy by switching BWP, and can also save energy by normally operating the DRX monitoring mechanism, thereby achieving more effective energy saving for the target terminal.

[0052] Of course, it is not necessary to achieve all the advantages described above at the same time when implementing any product or method of the present application. BRIEF DESCRIPTION OF THE DRAWINGS

[0059] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field based on this application are within the scope of protection of this application.

[0060] In the 5G NR system, broadband BWP and narrowband BWP can be configured for the terminal, and the broadband BWP and narrowband BWP can be adaptively switched according to the amount of data scheduled by the terminal to achieve terminal energy saving.

[0061] On the other hand, DRX (Discontinuous Reception) is also a terminal energy-saving mechanism. The basic concept is to set a DRX cycle, including an active period and a dormant period. The active period is usually represented by the DRXonduration (DRX on-duration), which is well known in the art, and the dormant period is usually represented by the Opportunity for DRX (DRX on-duration). After configuring DRX for a terminal, the terminal monitors and receives the PDCCH (Physical Downlink Control Channel) during the active period. During the dormant period, the receiving circuit can be disabled to reduce power consumption and achieve terminal energy saving.

[0062] In existing solutions, resource allocation is usually based on a single BWP, and a related algorithm is used to calculate the DRX cycle for the BWP. That is, for each user terminal, the BWP resources allocated to it and the DRX cycle are one-to-one corresponding, and a DRX can only be configured with its corresponding BWP at the same time.

[0063] In order to simultaneously configure broadband BWP, narrowband BWP and DRX for a terminal, and realize simultaneous configuration of one DRX with broadband BWP and narrowband BWP to save energy more effectively, the embodiments of the present application provide a method, device, electronic device and storage medium for configuring a subset bandwidth BWP.

[0064] See also Figure 1 , Figure 1 A flowchart of a method for configuring a subset bandwidth BWP provided in an embodiment of the present application is provided. The method may include the following steps:

[0065] S101: Detect whether a target terminal accessing a base station supports multi-BWP configuration. If so, determine broadband BWP resources and narrowband BWP resources to be allocated for the target terminal.

[0066] Among them, the terminal is not limited to connecting to the base station by first access, switching or re-establishment. In the embodiment of the present application, for the convenience of explanation, any terminal that establishes a connection with the base station is marked as a target terminal. There can be multiple target terminals, and the configuration method of the subset bandwidth BWP provided in the embodiment of the present application can be applicable to any target terminal.

[0067] It is easy to understand that after the target terminal just establishes a connection with the base station, the base station needs to allocate communication resources to the target terminal, usually including time-frequency resources.

[0068] The base station can detect whether the target terminal supports multiple BWP configurations. If the target terminal supports multiple BWP configurations, the base station can determine the broadband BWP resources and narrowband BWP resources to be allocated to the target terminal.

[0069] Specifically, if the target terminal is an SA (Standalone, independent networking) terminal, when accessing the base station, the base station has not yet determined whether the terminal has the capability of multiple BWPs, it will first be configured according to the broadband BWP resources. After further obtaining the terminal capabilities, if the terminal capabilities support multiple BWP configurations, narrowband BWP resources will be allocated to it.

[0070] If the target terminal is an NSA (Non-Standalone) terminal, it will carry capability parameters when accessing the base station. The base station will determine whether the target terminal can support multiple BWP configurations based on the capability parameters. If it does, the base station will determine the broadband BWP resources and narrowband BWP resources to be allocated for the target terminal.

[0071] The BWP is a subset of the total cell bandwidth. In the frequency domain, the bandwidth range of the wideband BWP can generally include the bandwidth range of the narrowband BWP. For example, the bandwidth range of the wideband BWP is 20MHz-60MHz, and the bandwidth range of the narrowband BWP is 30MHz-40MHz.

[0072] In addition, it may also be required that the bandwidth range of the narrowband BWP includes the bandwidth resources of the initial BWP, wherein the initial BWP may be set according to actual needs or relevant protocols.

[0073] As an example, some BWP resources, such as PRACH (Physical Random Access Channel) resources, may be configured in the initial BWP, and other determined BWPs may reuse the above resources in the initial BWP to save common resources.

[0074] In addition, since the bandwidth range of the wideband BWP includes the bandwidth range of the narrowband BWP, the wideband BWP can reuse some resources of the narrowband BWP.

[0075] As an example, during the resource initialization phase, the base station can configure PUCCH (Physical uplink control channel) resources in the narrowband BWP, and the wideband BWP can directly reuse other PUCCH time-frequency resources in the narrowband BWP resources except for the SRS (Sounding reference signal). Specifically, the base station initializes PUCCH resources in the narrowband BWP, and the wideband BWP can directly map other PUCCH resources in the narrowband BWP except for the SRS resources.

[0076] For example, for a narrowband BWP with a bandwidth range of 30MHz-40MHz, if the PUCCH resources are configured in the bandwidth range of 35MHz-35.1MHz during the resource initialization phase, then for a wideband BWP with a bandwidth range of 20MHz-60MHz, the PUCCH resources of the BWP can be directly reused, that is, the PUCCH resources are also configured in the bandwidth range of 35MHz-35.1MHz.

[0077] Regarding SRS resources, since the bandwidth of SRS affects the generation of its sequence, and the SRS bandwidth in the wideband BWP is different from that in the narrowband BWP, the generated SRS sequence is also different, that is, the wideband BWP cannot reuse the SRS resources of the narrowband BWP.

[0078] The SRS resources also include time domain resources and frequency domain resources. The frequency domain resources are the bandwidth occupied by the SRS, and the time domain resources can be understood as the time slots used to send and receive SRS signals.

[0079] S102: Determine a discontinuous reception (DRX) cycle for the target terminal.

[0080] In the embodiment of the present application, for a target terminal that establishes a connection with a base station, in addition to determining the broadband BWP resources and narrowband BWP resources to be allocated, a DRX cycle for the target terminal may also be determined.

[0081] DRX is a terminal energy-saving mechanism. In this step, a DRX cycle can be set for the target terminal, which usually includes an active period and a dormant period.

[0082] Specifically, the DRX cycle for the target terminal may be determined based on the determined broadband BWP resources to be allocated. The method for calculating the DRX cycle using a related algorithm based on the BWP resources may be found in related art.

[0083] S103: Determine whether the narrowband BWP resource conflicts with the DRX cycle.

[0084] In the embodiment of the present application, if a target terminal is configured with a wideband BWP, a narrowband BWP, and a DRX simultaneously, it is necessary to ensure that the DRX does not conflict with the wideband BWP, and vice versa. Therefore, before configuring the wideband BWP, narrowband BWP, and DRX, a conflict determination must be performed.

[0085] Since the wideband BWP is usually a mandatory BWP and the DRX cycle is calculated based on the wideband BWP resources, the wideband BWP resources will not conflict with the DRX cycle. Therefore, it is only necessary to determine whether the narrowband BWP resources conflict with the DRX cycle.

[0086] Since the DRX cycle is for the time domain, determining whether the narrowband BWP resources conflict with the DRX cycle can be understood as determining whether the time domain resources occupied by the narrowband BWP conflict with the DRX cycle.

[0087] In one embodiment of the present application, it is possible to determine whether the narrowband BWP resource conflicts with the DRX cycle in the following manner. Figure 2 , Figure 2 A flowchart of determining whether narrowband BWP resources conflict with a DRX cycle provided in an embodiment of the present application may include the following steps:

[0088] S201: Determine whether the activation period can simultaneously include the SRS transmission and reception time slots and the CSI RS transmission and reception time slots.

[0089] Among them, CSI RS is a channel state information reference signal. Like the SRS signal, the base station also needs to allocate time slots for it to send and receive signals.

[0090] It can be determined whether the activation period can simultaneously include the SRS transmission and reception time slots and the CSI RS transmission and reception time slots. If they can be included at the same time, S202 is executed, i.e., it is determined that the narrowband BWP resource does not conflict with the DRX cycle; if they cannot be included at the same time, S203 is executed, i.e., it is determined that the narrowband BWP resource conflicts with the DRX cycle.

[0091] As an example, for time slots 0-100, the DRX activation period is time slots 0-60, and the base station allocates the 40th and 45th time slots for the transmission and reception of the SRS signal of the narrowband BWP of the target terminal, respectively. The base station allocates the 50th and 55th time slots for the transmission and reception of the CSI RS signal of the narrowband BWP of the target terminal, respectively. In this case, the activation period can include both the transmission and reception time slots of the SRS and the transmission and reception time slots of the CSI RS, and it is determined that the narrowband BWP resource does not conflict with the DRX cycle. If the base station allocates the 70th time slot for the transmission or reception time slot of the SRS signal of the narrowband BWP of the target terminal, the activation period cannot include the transmission or reception time slot of the SRS of the narrowband BWP, and it is determined that the narrowband BWP resource conflicts with the DRX cycle.

[0092] If the activation period cannot simultaneously include the narrowband BWP SRS transmission and reception time slots and the CSI RS transmission and reception time slots, it means that when the target terminal operates in the activation period, it cannot normally transmit and receive the narrowband BWP SRS signal or CSI RS, and the target terminal will not function normally. In other words, the DRX activation period and narrowband BWP cannot be carried out at the same time. Therefore, in this case, narrowband BWP and DRX cannot be configured simultaneously.

[0093] On the contrary, if the narrowband BWP resource does not conflict with the DRX cycle, the narrowband BWP and DRX of the target terminal may not affect each other, that is, they can be configured at the same time.

[0094] S104: If there is no conflict, configuring a broadband BWP for the target terminal based on the determined broadband BWP resources, configuring a narrowband BWP for the target terminal based on the determined narrowband BWP resources, and configuring DRX for the target terminal based on the determined DRX cycle, wherein the broadband BWP and the narrowband BWP share the DRX cycle.

[0095] In the embodiment of the present application, as described above, if the narrowband BWP resource does not conflict with the DRX cycle, they can be configured simultaneously.

[0096] Specifically, a broadband BWP is configured for the target terminal based on the determined broadband BWP resources, a narrowband BWP is configured for the target terminal based on the determined narrowband BWP resources, and a DRX is configured for the target terminal based on the determined DRX cycle, wherein the broadband BWP and the narrowband BWP share the DRX cycle.

[0097] In the embodiments of the present application, the wideband BWP and narrowband BWP share the DRX cycle, which can also be understood as the wideband BWP and narrowband BWP sharing the same DRX monitoring mechanism. That is, regardless of whether the target terminal is operating in the wideband BWP or narrowband BWP, the configured DRX monitoring mechanism can operate normally, monitoring and receiving the PDCCH during the DRX active period and ceasing to monitor and receive the PDCCH during the DRX dormant period. Therefore, even if the target terminal switches BWPs based on service needs, the normal operation of DRX is not affected.

[0098] The method for configuring the subset bandwidth BWP provided in the embodiment of the present application is applied to detect whether the target terminal accessing the base station supports multi-BWP configuration. If supported, the broadband BWP resources and narrowband BWP resources to be allocated are determined for the target terminal; the discontinuous reception DRX cycle for the target terminal is determined; and it is determined whether the narrowband BWP resources conflict with the DRX cycle. If not, the broadband BWP is configured for the target terminal based on the determined broadband BWP resources, the narrowband BWP is configured for the target terminal based on the determined narrowband BWP resources, and the DRX is configured for the target terminal based on the determined DRX cycle. It can be seen that the embodiment of the present application takes into account that the DRX cycle determined by the base station for the target terminal may conflict with the narrowband BWP resource, and thus provides a configuration method for determining whether to configure multiple BWPs and DRX at the same time by judging whether the narrowband BWP resource conflicts with the DRX cycle. When it is judged that the narrowband BWP resource does not conflict with the DRX cycle, the target terminal can be configured with broadband BWP, narrowband BWP and DRX at the same time. The broadband BWP and narrowband BWP share the same DRX cycle, so that the target terminal can save energy by switching BWP, and can also save energy by normally operating the DRX monitoring mechanism, thereby achieving more effective energy saving for the target terminal.

[0099] In one embodiment of the present application, if the narrowband BWP resource conflicts with the DRX cycle, it indicates that narrowband BWP and DRX cannot be configured simultaneously. In this case, only wideband BWP and DRX may be configured for the target terminal. Specifically, the wideband BWP is configured for the target terminal based on the determined wideband BWP resource, and the DRX is configured for the target terminal based on the determined DRX cycle.

[0100] In one embodiment of the present application, if a wideband BWP, a narrowband BWP, and DRX are currently configured, when DRX needs to be adjusted, a target DRX cycle can be determined. A determination is made as to whether the currently configured narrowband BWP conflicts with the target DRX cycle; if not, the DRX cycle is adjusted to the target DRX cycle.

[0101] The target DRX cycle indicates the DRX cycle to be adjusted, including the active period and dormant period to be adjusted. The target DRX cycle may be reasonably allocated by the base station based on the current communication state.

[0102] As an example, the active period of the target DRX cycle is time slots 10-70. Before adjusting the DRX cycle, a determination is made as to whether the currently configured narrowband BWP conflicts with the target DRX cycle. The specific determination process is described above. For example, a determination is made as to whether the active period of the target DRX cycle, time slots 10-70, simultaneously includes the SRS transmit and receive time slots and the CSI RS transmit and receive time slots of the currently configured narrowband BWP. If so, the determination is made that the currently configured narrowband BWP does not conflict with the target DRX cycle. The DRX cycle can then be adjusted to the target DRX cycle.

[0103] When adjusting DRX, you can only adjust the DRX cycle, that is, only reconfigure the DRX cycle; or, reconfigure the entire DRX, that is, delete the current DRX configuration parameters and reconfigure a new DRX. This embodiment of the present application does not limit this.

[0104] The adjusted DRX and narrowband BWP can operate without affecting each other, thereby achieving more effective energy saving for the target terminal equipment.

[0105] If the currently configured narrowband BWP conflicts with the target DRX cycle, it means that if the DRX cycle is adjusted, the adjusted DRX cannot run simultaneously with the narrowband BWP. In this case, the currently configured DRX can be deleted.

[0106] Since DRX is deleted, the target terminal is only configured with a wideband BWP and a narrowband BWP. In order to achieve reasonable energy saving of the target terminal, switching between the wideband BWP and the narrowband BWP can be performed under specific conditions.

[0107] Among them, the air interface configuration affecting BWP switching may include: defaultBWP (default Downlink BWP-Id, default downlink BWP identifier), firstActive (firstActive BWP-Id, initial activation BWP identifier), bwp-InactivityTimer (BWP-inactivity timer), where bwp-InactivityTimer represents the timer for switching BWP. Assuming that bwp-InactivityTimer is set to 5ms, if the target terminal does not receive the uplink and downlink scheduling DCI within 5ms, the target terminal will switch from the initially activated BWP, i.e., firstActive, to defaultBWP.

[0108] Different air interface configurations can be performed according to specific application scenarios.

[0109] For example, if only one BWP is configured for the terminal, bwp-InactivityTimer is not configured, and there is no need to configure defaultBWP. You only need to configure firstActive as the current BWP.

[0110] If two BWPs are configured for a terminal, you need to configure bwp-InactivityTimer, set defaultBWP to narrowband BWP, and set firstActive to broadband BWP.

[0111] If two BWPs are configured for a terminal but BWP switching is not supported, do not configure bwp-InactivityTimer. Instead, configure defaultBWP and firstActive as required. For example, set defaultBWP to BWP1 and firstActive to BWP2.

[0112] In particular, for terminals that have established VONR (Voice over New Radio, calls under 5G access), due to the high call quality requirements of VONR, it is necessary to ensure that it works on the broadband BWP. Therefore, when VONR is established and two BWPs have been configured, bwp-InactivityTimer is deleted, and both defaultBWP and firstActive are set to broadband BWP.

[0113] If the VONR service is deleted, reconfigure bwp-InactivityTimer, set defaultBWP to narrowband BWP, and set firstActive to broadband BWP.

[0114] In the embodiment of the present application, the inactivity duration of the target terminal reaches the BWP inactivity timer, triggering the target terminal to perform a switch from the broadband BWP to the narrowband BWP.

[0115] Specifically, the inactivity duration of the target terminal can be understood as the duration of not receiving DCI (downlink control information). When the duration reaches the BWP inactivity timer bwp-InactivityTimer, it means that the target terminal has no business for a long time. In order to save energy, the target terminal can automatically switch BWP, that is, switch from broadband BWP to narrowband BWP.

[0116] On the other hand, the base station instructs the target terminal to perform a switch from a narrowband BWP to a wideband BWP through RRC (Radio Resource Control) reconfiguration signaling or DCI signaling. Specifically, when the target terminal is currently operating in a narrowband BWP and the base station determines that the target terminal needs to schedule a large amount of data and the narrowband BWP may not be able to meet the scheduling requirements, it can notify the target terminal to perform a BWP switch through RRC signaling or DCI signaling, and the target terminal switches from the narrowband BWP to the wideband BWP.

[0117] In particular, for the target terminal that has established VONR, it continues to work in the broadband BWP and does not perform BWP switching.

[0118] In addition, if the target terminal does not support multiple BWP configurations, only one BWP may be configured for the target terminal, usually a BWP with a wider bandwidth range. In this case, in order to save energy for the target terminal, DRX may also be configured for the target terminal.

[0119] For ease of understanding, the following Figure 3 The configuration method of the subset bandwidth BWP provided in the embodiment of the present application is further explained.

[0120] See also Figure 3 , Figure 3 Another flowchart of a method for configuring a subset bandwidth BWP provided in an embodiment of the present application may include the following steps:

[0121] S301: Detect whether a target terminal accessing a base station supports multi-BWP configuration. If so, determine broadband BWP resources and narrowband BWP resources to be allocated for the target terminal.

[0122] If the target terminal does not support multiple BWP configurations, S305 is executed to configure a broadband BWP and DRX for the target terminal. Specifically, the broadband BWP is configured for the target terminal based on the determined broadband BWP resources, and the DRX is configured for the target terminal based on the determined DRX cycle.

[0123] S302: Determine a discontinuous reception (DRX) cycle for the target terminal.

[0124] S303: Determine whether the narrowband BWP resource conflicts with the DRX cycle.

[0125] S304: If there is no conflict, configuring a broadband BWP for the target terminal based on the determined broadband BWP resources, configuring a narrowband BWP for the target terminal based on the determined narrowband BWP resources, and configuring DRX for the target terminal based on the determined DRX cycle.

[0126] If there is a conflict, S306 is executed to configure the broadband BWP and DRX for the target terminal. Specifically, the broadband BWP is configured for the target terminal based on the determined broadband BWP resources, and the DRX is configured for the target terminal based on the determined DRX cycle.

[0127] Corresponding to the embodiment of the method for configuring the subset bandwidth BWP provided in the embodiment of the present application, the embodiment of the present application also provides a device for configuring the subset bandwidth BWP, see Figure 4 , the device may include the following modules:

[0128] A detection module 401 is configured to detect whether a target terminal accessing a base station supports multi-BWP configuration, and if so, to determine a broadband BWP resource and a narrowband BWP resource to be allocated for the target terminal;

[0129] A determination module 402 is configured to determine a discontinuous reception (DRX) cycle for a target terminal;

[0130] The judging module 403 is configured to judge whether the narrowband BWP resource conflicts with the DRX cycle;

[0131] The configuration module 404 is used to configure a broadband BWP for the target terminal based on the determined broadband BWP resources, configure a narrowband BWP for the target terminal based on the determined narrowband BWP resources, and configure DRX for the target terminal based on the determined DRX cycle if there is no conflict, wherein the broadband BWP and the narrowband BWP share the DRX cycle.

[0132] The device for configuring the subset bandwidth BWP provided in the embodiment of the present application is used to detect whether the target terminal accessing the base station supports multi-BWP configuration. If so, the broadband BWP resources and narrowband BWP resources to be allocated are determined for the target terminal; the discontinuous reception DRX cycle for the target terminal is determined; and it is determined whether the narrowband BWP resources conflict with the DRX cycle. If not, the broadband BWP is configured for the target terminal based on the determined broadband BWP resources, the narrowband BWP is configured for the target terminal based on the determined narrowband BWP resources, and the DRX is configured for the target terminal based on the determined DRX cycle.

When it is judged that the narrowband BWP resource does not conflict with the DRX cycle, the target terminal can be configured with broadband BWP, narrowband BWP and DRX at the same time. The broadband BWP and narrowband BWP share the same DRX cycle, so that the target terminal can save energy by switching BWP, and can also save energy by normally operating the DRX monitoring mechanism, thereby achieving more effective energy saving for the target terminal.

[0135] Determining whether the DRX activation period can simultaneously include the SRS transmission and reception time slots and the CSI RS transmission and reception time slots;

[0136] If yes, determining that the narrowband BWP resource does not conflict with the DRX cycle;

[0137] If not, it is determined that the narrowband BWP resource conflicts with the DRX cycle.

[0138] In one embodiment of the present application, the configuration module 404 may also be configured to configure a wideband BWP for the target terminal based on the determined wideband BWP resource and configure DRX for the target terminal based on the determined DRX cycle if the narrowband BWP resource conflicts with the DRX cycle.

[0139] In one embodiment of the present application, Figure 4 Based on the device shown, an adjustment module may be further included, and the adjustment module is used to:

[0140] When DRX needs to be adjusted and wideband BWP and narrowband BWP are currently configured, determine the target DRX cycle;

[0141] Determine whether the currently configured narrowband BWP conflicts with the target DRX cycle;

[0142] If there is no conflict, the DRX cycle is adjusted to the target DRX cycle.

[0143] In one embodiment of the present application, the adjustment module 404 may also be used to:

[0144] If the currently configured narrowband BWP conflicts with the target DRX cycle, the currently configured DRX is deleted.

[0145] In one embodiment of the present application, the broadband BWP resource multiplexes other PUCCH time-frequency resources in the narrowband BWP resource except the SRS resource.

[0146] In one embodiment of the present application, the adjustment module 404 may also be used to:

[0147] If the target terminal does not support multi-BWP configuration, configure broadband BWP and DRX for the target terminal.
