Description

Background

In the 5G NR (New Radio, New air interface), a plurality of dedicated BWPs (Bandwidth part, subset Bandwidth) may be configured for the terminal.

Currently, if a terminal supports multi-BWP configuration, two BWPs are typically configured for the terminal, including one broadband BWP and one narrowband BWP.

When the terminal scheduling data volume is small, the terminal can work on narrow-band BWP; when the amount of scheduled data of the terminal is large, the terminal needs to operate on broadband BWP. Wherein, the larger the working bandwidth is, the higher the sampling rate is, and the higher the power consumption is.

Therefore, the purpose of saving energy of the terminal can be achieved by adaptively adjusting the bandwidth size adopted by the terminal for receiving and sending.

However, only switching between broadband BWP and narrowband BWP provides limited power savings for the terminal.

Detailed Description

The technical solutions in the embodiments of the present application will be described clearly and completely with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only some embodiments of the present application, and not all embodiments. All other embodiments that can be derived by one of ordinary skill in the art from the description herein are intended to be within the scope of the present disclosure.

In the 5G NR system, a broadband BWP and a narrowband BWP may be configured for a terminal, and the broadband BWP and the narrowband BWP may be adaptively switched according to the size of data amount scheduled by the terminal, so as to achieve terminal power saving.

On the other hand, DRX (Discontinuous Reception) is also a terminal power saving mechanism. The basic idea is as follows: and setting a DRX period comprising an active period and a dormant period. The active period is generally denoted as DRX on duration (DRX start duration) as is well known in the art, and the dormant period is generally denoted as Opportunity for DRX as is well known in the art. After configuring DRX for the terminal, the terminal monitors and receives a PDCCH (Physical Downlink Control Channel) in an active period, and may turn off a receiving circuit in a sleep period to reduce power consumption, thereby implementing terminal energy saving.

In the existing scheme, usually based on resource allocation of a single BWP, a related algorithm is adopted to calculate a DRX cycle for the BWP, that is, for each user terminal, the allocated BWP resource and DRX cycle are in one-to-one correspondence, and one DRX can only be configured simultaneously with the BWP corresponding to the DRX.

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

Referring to fig. 1, fig. 1 is a flowchart illustrating a method for configuring a subset bandwidth BWP according to an embodiment of the present application, where the method may include the following steps:

s101: detecting whether a target terminal accessed to a base station supports multi-BWP configuration, and if so, determining broadband BWP resources and narrowband BWP resources to be allocated for the target terminal.

In this embodiment, for convenience of description, any terminal establishing connection with the base station is marked as a target terminal, and the target terminals may be multiple terminals, and the configuration method for the subset bandwidth BWP provided in this embodiment may be applied to any target terminal.

As will be readily appreciated, immediately after the target terminal establishes a connection with the base station, the base station needs to allocate communication resources, typically including time-frequency resources, for the target terminal.

The base station may detect whether the target terminal supports multi-BWP configuration, and may determine a broadband BWP resource and a narrowband BWP resource to be allocated thereto if the target terminal supports multi-BWP configuration.

Specifically, if the target terminal is an SA (stand alone) terminal, and when accessing the base station, the base station does not determine whether the terminal has the capability of multiple BWPs, the terminal is configured according to the broadband BWP resource, and after further acquiring the terminal capability, if the terminal capability supports the multiple BWP configuration, the terminal is then allocated with the narrowband BWP resource.

If the target terminal is an NSA (Non-Standalone, Non-independent networking) terminal, the capability parameter is carried when the target terminal accesses the base station, the base station judges whether the target terminal can support multi-BWP configuration according to the capability parameter, and if so, the base station determines broadband BWP resources and narrowband BWP resources to be allocated for the target terminal.

Where BWP is a subset of the total bandwidth of the cell, the bandwidth range of the wideband BWP may generally include the bandwidth range of the narrowband BWP in the frequency domain. As an example, the bandwidth of the broadband BWP is in the range of 20MHz-60MHz, and the bandwidth of the narrowband BWP is in the range of 30MHz-40 MHz.

Furthermore, the bandwidth range of the narrowband BWP may also be required to include the bandwidth resources of the initial BWP, where the initial BWP may be set according to actual requirements or related protocols.

As an example, a partial BWP resource, for example, a PRACH (Physical Random Access Channel) resource, may be configured in the initial BWP, and the determined other BWPs may all multiplex the above resources in the initial BWP, so as to save common resources.

Furthermore, since the bandwidth range of the broadband BWP encompasses the bandwidth range of the narrowband BWP, the broadband BWP may multiplex a portion of the resources of the narrowband BWP.

As an example, in the resource initialization phase, the base station may configure PUCCH (Physical uplink control channel) resources in the narrowband BWP, and the wideband BWP may directly multiplex other PUCCH time-frequency resources except SRS (Sounding reference signal) in the narrowband BWP resources. Specifically, the base station initializes PUCCH resources in the narrowband BWP, and the wideband BWP may directly map PUCCH resources other than SRS resources on the narrowband BWP.

For example, for a narrowband BWP with a bandwidth range of 30MHz-40MHz, if the PUCCH resource is configured in the bandwidth range of 35MHz-35.1MHz in the resource initialization phase, the PUCCH resource of the BWP may be directly multiplexed for a wideband BWP with a bandwidth range of 20MHz-60MHz, that is, the PUCCH resource is also configured in the bandwidth range of 35MHz-35.1 MHz.

For the SRS resource, the SRS bandwidth affects the sequence generation, and the SRS bandwidth in the wideband BWP is different from the SRS bandwidth in the narrowband BWP, so the SRS sequence generated is also different, that is, the wideband BWP cannot multiplex the SRS resource of the narrowband BWP.

The SRS resources also include time domain resources and frequency domain resources, where the frequency domain resources are bandwidths occupied by the SRS, and the time domain resources may be understood as time slots used for transmitting and receiving SRS signals.

S102: a discontinuous reception, DRX, cycle for the target terminal is determined.

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

DRX is a terminal power saving mechanism. In this step, a DRX cycle may be set for the target terminal, typically including an active period and a dormant period.

Specifically, the DRX cycle for the target terminal may be determined based on the determined broadband BWP resource to be allocated. The related art may be referred to as a method for calculating the DRX cycle using a related algorithm according to the BWP resource.

S103: it is determined whether the narrowband BWP resources conflict with the DRX cycle.

In the embodiment of the present application, if the broadband BWP, the narrowband BWP and the DRX are configured for the target terminal at the same time, it is necessary to ensure that the DRX does not conflict with the broadband BWP and the DRX does not conflict with the narrowband BWP. Therefore, before configuring the broadband BWP, the narrowband BWP, and the DRX, collision determination needs to be performed.

Since the broadband BWP is typically the BWP that must be configured and the DRX cycle is calculated based on the broadband BWP resources, the broadband BWP resources do not collide with the DRX cycle. Therefore, it is only necessary to determine whether the narrowband BWP resource conflicts with the DRX cycle.

Since the DRX cycle is time domain specific, determining whether the narrowband BWP resource conflicts with the DRX cycle may be understood as determining whether the time domain resource occupied by the narrowband BWP conflicts with the DRX cycle.

In an embodiment of the present application, it may be determined whether the narrowband BWP resource collides with the DRX cycle in the following manner. Referring to fig. 2, fig. 2 is a schematic flowchart of determining whether a narrowband BWP resource conflicts with a DRX cycle according to an embodiment of the present application, where the flowchart may include the following steps:

s201: and judging whether the activation period can simultaneously contain the SRS transmission and reception time slot and the CSI RS transmission and reception time slot.

The CSI RS is a channel state information reference signal, and the base station needs to allocate slots for transmitting and receiving signals to the CSI RS as well as the SRS signal.

It may be determined whether the active period can simultaneously include the SRS transmission and reception slot and the CSI RS transmission and reception slot, and if so, S202 is performed, i.e., it is determined that the narrowband BWP resource does not collide with the DRX cycle; if the narrowband BWP resources and the DRX cycle are not able to be simultaneously included, S203 is performed, i.e., it is determined that the narrowband BWP resources and the DRX cycle collide.

As an example, for 0-100 slots, the active period of DRX is 0-60 slots, the transmission and reception slots allocated by the base station for the SRS signal of the narrowband BWP of the target terminal are respectively the 40 th slot and the 45 th slot, and the transmission and reception slots allocated by the base station for the CSI RS signal of the narrowband BWP of the target terminal are respectively the 50 th slot and the 55 th slot, then the active period can simultaneously include the transmission and reception slots of SRS and the transmission and reception slots of CSI RS, and it is determined that the narrowband BWP resources do not collide with the DRX cycle. If the transmitting or receiving time slot allocated by the base station for the SRS signal of the narrowband BWP of the target terminal is the 70 th time slot, the active period cannot include the transmitting or receiving time slot of the SRS of the narrowband BWP, and it is determined that the narrowband BWP resource collides with the DRX cycle.

If the active period cannot simultaneously include the sending and receiving time slot of the SRS of the narrowband BWP and the sending and receiving time slot of the CSI RS, which indicates that the target terminal cannot normally send and receive the SRS signal of the narrowband BWP or the CSI RS when the target terminal operates in the active period, the target terminal cannot normally operate. In other words, the active period of DRX and the narrowband BWP cannot be performed simultaneously, and thus, in this case, the narrowband BWP and DRX cannot be configured simultaneously.

Otherwise, the narrowband BWP resource does not conflict with the DRX cycle, and the narrowband BWP and DRX of the target terminal may not be affected by each other, i.e. may be configured simultaneously.

S104: and if not, configuring the broadband BWP for the target terminal based on the determined broadband BWP resources, configuring the 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 period, wherein the broadband BWP and the narrowband BWP share the DRX period.

In the embodiment of the present application, as described above, if the narrowband BWP resource does not conflict with the DRX cycle, the narrowband BWP resource and the DRX cycle may be configured simultaneously.

Specifically, the target terminal is configured with a broadband BWP based on the determined broadband BWP resources, configured with a narrowband BWP based on the determined narrowband BWP resources, and configured with DRX based on the determined DRX cycle, where the broadband BWP and the narrowband BWP share the DRX cycle.

In the embodiment of the present application, the broadband BWP and the narrowband BWP share the DRX cycle, which may also be understood as an listening mechanism in which the broadband BWP and the narrowband BWP share the same DRX. Namely: the configured monitoring mechanism of DRX can be normally operated no matter the target terminal works in broadband BWP or narrowband BWP, the PDCCH is monitored and received in the active period of DRX, and the PDCCH is monitored and received in the dormant period of DRX. Therefore, even if the target terminal performs BWP handover according to the service requirement, the normal operation of DRX is not affected.

By applying the method for configuring the bandwidth BWP in the subset provided in the embodiment of the present application, it is detected whether a target terminal accessing a base station supports multi-BWP configuration, and if so, a wideband BWP resource and a narrowband BWP resource to be allocated are determined for the target terminal; determining a Discontinuous Reception (DRX) cycle for a target terminal; judging whether the narrow band BWP resource conflicts with a DRX period; and if not, configuring the broadband BWP for the target terminal based on the determined broadband BWP resources, configuring the 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 period. It can be seen that, in the embodiment of the present application, in consideration that the DRX cycle determined by the base station for the target terminal may conflict with the narrowband BWP resource, a configuration method for determining whether to configure multiple BWPs and DRX simultaneously by determining whether the narrowband BWP resource conflicts with the DRX cycle is provided, and in case that it is determined that the narrowband BWP resource does not conflict with the DRX cycle, the broadband BWP, the narrowband BWP and the narrowband BWP may be configured for the target terminal simultaneously, and the broadband BWP and the narrowband BWP share the same DRX cycle, so that the target terminal may not only save energy consumption by switching BWPs, but also may normally operate an DRX monitoring mechanism to save energy consumption, thereby achieving more efficient energy saving for the target terminal.

In an embodiment of the present application, if the narrowband BWP resource collides with the DRX cycle, it means that the narrowband BWP and DRX cannot be configured at the same time, in which case, the broadband BWP and DRX may be configured only for the target terminal. Specifically, the target terminal is configured with the broadband BWP based on the determined broadband BWP resources, and the target terminal is configured with the DRX based on the determined DRX cycle.

In an embodiment of the present application, if the broadband BWP, the narrowband BWP and the DRX are currently configured at the same time, when the DRX needs to be adjusted, the target DRX cycle may be determined. Judging whether the current configured narrowband BWP conflicts with a target DRX period; and if not, adjusting the DRX period to the target DRX period.

The target DRX cycle indicates a DRX cycle that needs to be adjusted, and includes an active period and a dormant period that need to be adjusted, and the target DRX cycle may be obtained by performing reasonable allocation by the base station based on the current communication state.

As an example, the active period of the target DRX cycle is 10-70 slots. It is determined whether the currently configured narrowband BWP conflicts with the target DRX cycle before the DRX cycle is adjusted. For example, whether the active period 10-70 slots of the target DRX cycle can simultaneously include the SRS transmission and reception slots of the currently configured narrowband BWP and the CSI RS transmission and reception slots is determined, and if so, it is determined that the currently configured narrowband BWP does not collide with the target DRX cycle. The DRX cycle can be adjusted to the target DRX cycle.

When adjusting the DRX, only the cycle of the DRX may be adjusted, that is, only the cycle of the DRX is reconfigured; or, reconfiguring the DRX as a whole, that is, deleting the current DRX configuration parameter and reconfiguring a new DRX, which is not limited in the embodiment of the present application.

The adjusted DRX and the narrow-band BWP can not affect the operation mutually, thereby realizing more effective energy saving of the target terminal equipment.

If the currently configured narrowband BWP collides with the target DRX cycle, it means that the adjusted DRX cannot operate simultaneously with the narrowband BWP if the DRX cycle is adjusted, and in this case, the currently configured DRX may be deleted.

Since DRX is deleted and the target terminal is configured with only the broadband BWP and the narrowband BWP, a handover between the broadband BWP and the narrowband BWP may be performed under certain conditions in order to achieve reasonable power saving for the target terminal.

The air interface configuration that affects BWP switching may include: default Downlink BWP (default Downlink BWP-Id), first active BWP-Id, BWP-inactivity timer (BWP-inactivity timer), where BWP-inactivity timer represents a timer for switching BWP, and if BWP-inactivity timer is set to 5ms, if the target terminal does not receive uplink and Downlink scheduling DCI within 5ms, the target terminal will switch from the initially active BWP, i.e., first active to default BWP.

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

For example, if only one BWP is configured for the terminal, BWP-inactivytytimer is not configured, defaulttbwp is not required to be configured, and only firstActive is configured as the current BWP.

If two BWPs are configured for the terminal, BWP-InactivetyTimer needs to be configured, defaulttBPP is set as a narrow-band BWP, and firstActive is set as a wide-band BWP.

If two BWPs are configured for the terminal but the terminal does not support BWP switching, BWP-InactivetyTimer is not configured, and defaulttBWP and firstActive are configured according to requirements, for example, defaulttBWP is set as BWP1, and firstActive is set as BWP 2.

Particularly, for a terminal with built VONR (Voice over New Radio, call under 5G access), since the VONR call quality requirement is high, it needs to be guaranteed that BWP works in broadband, therefore, when the VONR is built and two BWPs are configured, BWP-inactivytimer is deleted, and defaulttbwp and firstActive are both set as broadband BWP.

If VONR service is deleted, BWP-InactivetyTimer is reconfigured, defaulttBWP is set as narrow band BWP, and firstActive is set as wide band BWP.

In the embodiment of the present application, the inactivity duration of the target terminal reaches the BWP inactivity timer, which triggers the target terminal to perform a handover from broadband BWP to narrowband BWP.

Specifically, the inactivity duration of the target terminal may be understood as a duration of no DCI (downlink control information) received, and when the duration reaches the BWP inactivity timer BWP-inactivity timer, it means that the target terminal has no traffic for a longer time, and the target terminal may automatically perform BWP handover, that is, handover from broadband BWP to narrowband BWP, in order to save energy.

On the other hand, the base station instructs the target terminal to perform handover from narrowband BWP to broadband BWP through RRC (Radio Resource Control) reconfiguration signaling or DCI signaling. Specifically, when the target terminal is currently operating in the narrowband BWP, and the base station determines that the target terminal needs a large amount of scheduling data and that the narrowband BWP may not meet the scheduling requirement, the base station may notify the target terminal to perform BWP handover through RRC signaling or DCI signaling, and the target terminal switches from the narrowband BWP to the broadband BWP.

Specifically, for the target terminal with the VONR established, the broadband BWP is continuously operated, and the BWP handover is not performed.

Furthermore, if the target terminal does not support multi-BWP configuration, only one BWP, typically a BWP with a wider bandwidth range, may be configured for the target terminal, in which case DRX may also be configured for the target terminal for power saving of the target terminal.

For the convenience of understanding, the configuration method of the subset bandwidth BWP provided by the embodiment of the present application is further described below with reference to fig. 3 of the drawings.

Referring to fig. 3, fig. 3 is another flowchart illustrating a method for configuring a subset bandwidth BWP according to an embodiment of the present application, where the method may include the following steps:

s301: detecting whether a target terminal accessed to a base station supports multi-BWP configuration, and if so, determining broadband BWP resources and narrowband BWP resources to be allocated for the target terminal.

If the target terminal does not support the multi BWP configuration, S305 is executed, that is, the target terminal is configured with the broadband BWP and DRX. The method specifically comprises the following steps: configuring broadband BWP for the target terminal based on the determined broadband BWP resources, and configuring DRX for the target terminal based on the determined DRX cycle.

S302: a discontinuous reception, DRX, cycle for the target terminal is determined.

S303: it is determined whether the narrowband BWP resources conflict with the DRX cycle.

S304: and if not, configuring the broadband BWP for the target terminal based on the determined broadband BWP resources, configuring the 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 period.

If so, executing S306, that is, configuring broadband BWP and DRX for the target terminal. The method specifically comprises the following steps: configuring broadband BWP for the target terminal based on the determined broadband BWP resources, and configuring DRX for the target terminal based on the determined DRX cycle.

Corresponding to the embodiment of the method for configuring a subset bandwidth BWP provided in the embodiment of the present application, an embodiment of the present application further provides a device for configuring a subset bandwidth BWP, and referring to fig. 4, the device may include the following modules:

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

The configuration device of the bandwidth BWP of the subset provided by the embodiment of the application detects whether a target terminal accessed to a base station supports multi-BWP configuration, and if so, determines broadband BWP resources and narrowband BWP resources to be allocated for the target terminal; determining a Discontinuous Reception (DRX) cycle for a target terminal; judging whether the narrow-band BWP resource conflicts with a DRX period; and if not, configuring the broadband BWP for the target terminal based on the determined broadband BWP resources, configuring the 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 period. It can be seen that, in the embodiments of the present application, in consideration that the DRX cycle determined by the base station for the target terminal may conflict with the narrowband BWP resource, a configuration method is provided for determining whether to configure multiple BWPs and DRX simultaneously by determining whether the narrowband BWP resource conflicts with the DRX cycle, and in case that it is determined that the narrowband BWP resource does not conflict with the DRX cycle, the broadband BWP, the narrowband BWP, and the narrowband BWP may be configured for the target terminal at the same time, and the broadband BWP and the narrowband BWP share the same DRX cycle, so that the target terminal may save energy by switching BWPs, and may also save energy by operating the DRX monitoring mechanism normally, thereby achieving more efficient energy saving for the target terminal.

In one embodiment of the present application, the narrowband BWP resources include transmission and reception slots for channel sounding reference signals SRS, transmission and reception slots for channel state information reference signals CSI RS; the DRX period comprises an active period and a dormant period;
