Description

A kind of activation method of bandwidth part and related equipment

technical field

The present invention relates to the technical field of information processing, and in particular, to a bandwidth part (BWP, Bandwidth Part) activation method, terminal device, network device, chip, computer-readable storage medium, computer program product and computer program.

Background technique

The system bandwidth supported by the New Radio (NR, New Radio) system is much larger than the maximum LTE system bandwidth of 20MHz. For some terminals, due to limited capabilities, it may not be able to support the entire system bandwidth. In order to improve scheduling efficiency and save energy from terminals From an electrical point of view, NR introduces the concept of bandwidth part BWP. In the RRC connection state, the network configures one or more BWPs for the terminal. The BWP mainly contains three parameters: Numerology: identifies the basic parameter set, that is, corresponds to a specific carrier spacing SCS; center frequency; bandwidth: less than or equal to the maximum system bandwidth.

It can be seen from this that BWP is a concept of frequency domain dimension. Meanwhile, in the discussion of R-15, it is assumed that at a point in time, the terminal supports only one active BWP. The so-called activation means that the terminal expects to receive signals on the bandwidth specified by the BWP, including data transmission (uplink and downlink), system messages and so on.

At the same time, the existing discussion also allows the network to trigger the terminal to switch between different BWPs configured by the network by sending an instruction, that is, to deactivate the current BWP and activate a new BWP.

In the description of the Spectrum Enhancement Project in R-16, it has been discussed that the terminal supports more than one activated BWP at the same time. However, the existing BWP switching mechanism does not support the scenario of activating multiple BWPs at the same time.

2 is a schematic flowchart of a method for activating a BWP provided by an embodiment of the present application, applied to a terminal device, including:

Step 201: Receive a first instruction on the first bandwidth part BWP; wherein, the first BWP is the BWP currently in an active state;

Step 202: Activate the second BWP based on the first instruction and start or restart a first timer; the first timer corresponds to the second BWP.

The aforementioned first BWP and the second BWP are configured on the same carrier or on different carriers.

It should be pointed out that the BWP in the active state described in this embodiment may also include the initial BWP (initial BWP) in the idle state; for example, the terminal receives on the initial BWP (that is, the first BWP in the idle state) The first command activates the second BWP.

Here, the first instruction is used to trigger the terminal device to start or restart the first timer and activate the second BWP; it can be understood that it is used to maintain the activation state of the initial BWP.

In addition, the first BWP here may be the initial BWP, and may not be the BWP configured in the connected state; the aforementioned second BWP may be configured in the connected state.

There is a scenario in this embodiment that: after the first instruction is received on the first BWP, the first BWP is kept in an activated state.

That is to say, at this time, it can be ensured that the first BWP and the second BWP are in an active state at the same time, which ensures that at least two BWPs can be in an active state at the same time.

It should be noted here that when the second BWP is deactivated, the following situations may exist. One situation is: if the first timer times out, the second BWP is deactivated. In this case, when the second BWP is deactivated, the first BWP can be kept in an activated state.

Another situation is: if the first timer expires, the second BWP is deactivated, and the third BWP is activated; wherein the third BWP is different from the second BWP. In this case, when the second BWP is deactivated, a new BWP, that is, the third BWP can be activated; that is, when the second BWP is deactivated, the third BWP and the first BWP can be activated at the same time , that is, at this time, it is also guaranteed that two BWPs are active at the same time.

Based on the foregoing solutions, various scenarios provided by this embodiment are introduced below:

scene 1,

A second timer is started or restarted; wherein the second timer corresponds to the first BWP.

That is to say, in this scenario, each BWP corresponds to a timer; that is, the first timer corresponds to the second BWP, and the second timing corresponds to the first BWP.

It should be noted that, in this embodiment, the second timer corresponds to the first BWP, which means that the second timer is used to time the operation of scheduling data in the first BWP.

Correspondingly, when the second instruction is received on the second BWP, the first timer is started or restarted based on the second instruction. The second instruction is used to schedule data transmission on the second BWP.

That is, each BWP restarts its corresponding timer when it receives a new command again. In this scenario, when the first instruction is received in the first BWP, the second BWP is activated and the first timer is started at the same time; when the second BWP receives the second instruction for the second BWP, the first The timer is restarted or started, and the second BWP may also be scheduled to send and receive data.

scene 2,

When a third instruction is received on the second BWP, a third timer is started or restarted based on the third instruction; wherein the third timer corresponds to the second BWP, and the third timer Different from the first timer.

In this scenario, one BWP may correspond to multiple timers, multiple timers may correspond to different scheduling data respectively, and multiple timers may be started at different times or in overlapping time periods. For example, when the second BWP is performing data scheduling, it receives the third instruction again. At this time, the third timer is started while scheduling the corresponding data based on the third instruction. At this time, the second BWP simultaneously starts the third timer. A timer corresponds to the scheduling of the first service data, and a third timer is enabled to correspond to the scheduling of the second service data.

In this scenario, if both the first timer and the third timer expire, the second BWP is deactivated. That is to say, when multiple timers corresponding to the second BWP all time out, the second BWP will be deactivated; and when one of the timers corresponding to the second BWP times out, it means that there are other timers. The corresponding service data is scheduled, so the second BWP will not be deactivated.

scene 3,

When the fourth instruction is received, the first timer is started or restarted based on the fourth instruction; wherein, the first timer also corresponds to the first BWP.

In this scenario, one timer can correspond to multiple BWPs; in this solution, the first timer can correspond to the first BWP in addition to the second BWP. That is to say, when the instruction is received again (it should be pointed out that the fourth instruction may be the same as the first instruction or different from the first instruction), the first timer can be restarted or started again, and the first Activation status of BWP.

In this scenario, the fourth instruction may be used to trigger the first timer corresponding to the first BWP to restart.

There is another situation: if the first timer times out, the first BWP is deactivated, and the third BWP is activated at the same time; wherein, the third BWP is different from the first BWP. That is to say, at this time, the first timer can correspond to multiple BWPs. Therefore, when the first timer times out, it can be controlled to deactivate the first BWP and then activate the third BWP. In addition, since the first timer corresponds to the first BWP and the second BWP, when the first timer expires, the second BWP is also deactivated.

At this time, the third BWP is different from the first BWP.

The first instruction includes:

Radio Resource Control (RRC, Radio Resource Control) dedicated signaling;

Or, a media access control (MAC, Media Access Control) control element (CE, ControlElement);

Or, Downlink Control Information (DCI, Downlink Control Information);

Or, a specific sequence.

The specific sequence may be a terminal-specific sequence or a common sequence of cells.

The DCI is a physical downlink control channel (PDCCH, transmission) scrambled by a radio network temporary identity (RNTI, Radio Network Temporary Identity); wherein, the RNTI includes a cell radio network temporary identity (C-RNTI, Cell-RNTI), CS - RNTI and first RNTI.

It should be pointed out that the first RNTI refers to an RNTI that is different from the various RNTIs timed in the prior art, that is, the PDCCH is scrambled by the first RNTI, so that the receiver, that is, the terminal equipment , it is determined that the currently received command is different from the command carried by the PDCCH scrambled by other RNTIs, that is, the command that can activate multiple BWPs at the same time. Further, the first RNTI in this embodiment is used for user data scheduling, and is different from C-RNTI and CS-RNTI; in addition, the MCS table can also be distinguished by using the first RNTI.

It should also be understood that the two BWPs (the first BWP and the second BWP) in this embodiment may be two downlink BWPs, or may be two uplink BWPs; however, this embodiment may not target two BWPs A case where one is a downstream BWP and the other is an upstream BWP. Further, this application focuses on the situation of at least two downlink BWPs, but does not exclude that the timer can be applied in the scenario of at least two uplink BWPs.

It can be seen that by adopting the above solution, when the first instruction is received on the first BWP, the second BWP can be activated and the first timer corresponding to the second BWP can be started or restarted; Active at the same time.

A schematic flowchart of a method for exchanging terminal capability information provided by an embodiment of the present application is applied to a network device, and the method includes:

sending a first instruction on the first BWP of the terminal device; the first instruction is used to trigger the terminal device to start or restart the first timer and activate the second BWP;

Wherein, the first BWP is the BWP currently in the active state of the terminal device; the first timer corresponds to the second BWP.

The aforementioned first BWP and the second BWP are configured on the same carrier or on different carriers.

It should be pointed out that the BWP in the active state described in this embodiment may also include the initial BWP (initial BWP) in the idle state; for example, the terminal receives on the initial BWP (that is, the first BWP in the idle state) The first command activates the second BWP.

Here, the first instruction is used to trigger the terminal device to start or restart the first timer and activate the second BWP, which can be understood as being used to maintain the activation state of the initial BWP.

In addition, the first BWP here may be the initial BWP, and may not be the BWP configured in the connected state; the aforementioned second BWP may be configured in the connected state.

There is a scenario in this embodiment that: when a first instruction is received on the first BWP, the first BWP is kept in an activated state. That is to say, at this time, it can be ensured that the first BWP and the second BWP are in an active state at the same time, which ensures that at least two BWPs can be in an active state at the same time.

Based on the foregoing solutions, various scenarios provided by this embodiment are introduced below:

scene 1,

A second timer is started or restarted; wherein the second timer corresponds to the first BWP.

That is to say, in this scenario, each BWP corresponds to a timer; that is, the first timer corresponds to the second BWP, and the second timing corresponds to the first BWP.

It should be noted that, in this embodiment, the second timer corresponds to the first BWP, which means that the second timer is used to time the operation of scheduling data in the first BWP.

Correspondingly, a second instruction is sent on the second BWP of the terminal device, and the second instruction causes the terminal device to start or restart the first timer. That is, through the second instruction, the first timer corresponding to the second BWP can be started or restarted. It can be understood that, before the first timer is started, the second BWP may be in a deactivated state after completing data scheduling, or may be in a data scheduling state, but since the second instruction is received again, it can be Restart the first timer.

scene 2,

A third instruction is sent on the second BWP of the terminal device, and the second instruction causes the terminal device to start or restart a third timer; wherein the third timer corresponds to the second BWP, And the third timer is different from the first timer.

In this scenario, one BWP may correspond to multiple timers, multiple timers may correspond to different scheduling data respectively, and multiple timers may be started at different times or in overlapping time periods. For example, when the second BWP is performing data scheduling, it receives the third instruction again. At this time, the third timer is started while scheduling the corresponding data based on the third instruction. At this time, the second BWP simultaneously starts the third timer. A timer corresponds to the scheduling of the first service data, and a third timer is enabled to correspond to the scheduling of the second service data.

In this scenario, if both the first timer and the third timer expire, the second BWP is deactivated. That is to say, when multiple timers corresponding to the second BWP all time out, the second BWP will be deactivated; and when one of the timers corresponding to the second BWP times out, it means that there are other timers. The corresponding service data is scheduled, so the second BWP will not be deactivated.

Scenario 3: Through a fourth instruction (the fourth instruction is the same as or different from the first instruction), a first timer is started or restarted based on the first instruction; wherein, the first timer also corresponds to the first BWP. In this scenario, the fourth instruction may be used to trigger the first timer corresponding to the first BWP to restart.

In this scenario, one timer can correspond to multiple BWPs; in this solution, the first timer can correspond to the first BWP in addition to the second BWP. That is to say, when the instruction is received again (it should be noted that the fourth instruction may be the same as the first instruction or different from the first instruction), the first timer can be restarted or started again to reactivate the first a BWP.

The first instruction includes:

RRC dedicated signaling;

Or, MAC CE;

or, DCI;

Or, a specific sequence.

The specific sequence may be a terminal-specific sequence or a common sequence of cells.

The DCI is transmitted by the PDCCH scrambled by the RNTI; wherein the RNTI includes the C-RNTI, the CS-RNTI and the first RNTI.

It should be pointed out that the first RNTI refers to an RNTI that is different from the various RNTIs timed in the prior art, that is, the PDCCH is scrambled by the first RNTI, so that the receiver, that is, the terminal equipment , it is determined that the currently received command is different from the command carried by the PDCCH scrambled by other RNTIs, that is, the command that can activate multiple BWPs at the same time. Further, the first RNTI in this embodiment is used for user data scheduling, and is different from C-RNTI and CS-RNTI; in addition, the MCS table can also be distinguished by using the first RNTI.

It should also be understood that the two BWPs (the first BWP and the second BWP) in this embodiment may be two downlink BWPs, or may be two uplink BWPs; however, this embodiment may not target two BWPs A case where one is a downstream BWP and the other is an upstream BWP. Further, this application focuses on the situation of at least two downlink BWPs, but does not exclude that the timer can be applied in the scenario of at least two uplink BWPs.

It can be seen that by adopting the above solution, when the first instruction is received on the first BWP, the second BWP can be activated and the first timer corresponding to the second BWP can be started or restarted; Active at the same time.

FIG. 3 is a terminal device provided by an embodiment of the application, including:

a first communication unit 31, configured to receive a first instruction on the first bandwidth part BWP; wherein, the first BWP is a BWP currently in an active state;

The first processing unit 32 is configured to activate the second BWP based on the first instruction and start or restart a first timer; the first timer corresponds to the second BWP.

The aforementioned first BWP and the second BWP are configured on the same carrier or on different carriers.

It should be pointed out that the BWP in the active state described in this embodiment may also include the initial BWP (initial BWP) in the idle state; for example, the terminal receives on the initial BWP (that is, the first BWP in the idle state) The first command activates the second BWP.

Here, the first instruction is used to trigger the terminal device to start or restart the first timer and activate the second BWP; it can be understood as being used to maintain the activation state of the initial BWP.

In addition, the first BWP here may be the initial BWP, and may not be the BWP configured in the connected state; the aforementioned second BWP may be configured in the connected state.

There is a scenario in this embodiment that the first processing unit 32 is configured to keep the first BWP in an activated state after receiving the first instruction on the first BWP.

That is to say, at this time, it can be ensured that the first BWP and the second BWP are in an active state at the same time, which ensures that at least two BWPs can be in an active state at the same time.

It should be noted here that when the second BWP is deactivated, the following situations may exist. One situation is: the first processing unit 32 is configured to deactivate the second BWP if the first timer times out. In this case, when the second BWP is deactivated, the first BWP can be kept in an activated state.

Another situation is: the first processing unit 32 is configured to deactivate the second BWP and activate the third BWP if the first timer expires, wherein the third BWP is different from the second BWP. In this case, when the second BWP is deactivated, a new BWP, that is, the third BWP can be activated; that is, when the second BWP is deactivated, the third BWP and the first BWP can be activated at the same time , that is, at this time, it is also guaranteed that two BWPs are active at the same time.

Based on the foregoing solutions, various scenarios provided by this embodiment are introduced below:

scene 1,

The first processing unit 32 is configured to start or restart a second timer; wherein, the second timer corresponds to the first BWP.

That is to say, in this scenario, each BWP corresponds to a timer; that is, the first timer corresponds to the second BWP, and the second timing corresponds to the first BWP.

It should be noted that, in this embodiment, the second timer corresponds to the first BWP, which means that the second timer is used to time the operation of scheduling data in the first BWP.

Correspondingly, the first processing unit 32 is configured to start or restart the first timer based on the second instruction when the first communication unit 31 receives the second instruction on the second BWP. The second instruction is used to schedule data transmission on the second BWP.

That is, each BWP restarts its corresponding timer when it receives a new command again. In this scenario, when the first instruction is received in the first BWP, the second BWP is activated and the first timer is started at the same time; when the second BWP receives the second instruction for the second BWP, the first The timer is restarted or started, and the second BWP may also be scheduled to send and receive data.

scene 2,

The first processing unit 32 is configured to start or restart a third timer based on the third instruction when a third instruction is received on the second BWP; wherein the third timer corresponds to the second BWP , and the third timer is different from the first timer.

In this scenario, one BWP may correspond to multiple timers, multiple timers may correspond to different scheduling data respectively, and multiple timers may be started at different times or in overlapping time periods. For example, when the second BWP is performing data scheduling, it receives the third instruction again. At this time, the third timer is started while scheduling the corresponding data based on the third instruction. At this time, the second BWP simultaneously starts the third timer. A timer corresponds to the scheduling of the first service data, and a third timer is enabled to correspond to the scheduling of the second service data.

In this scenario, the first processing unit 32 is configured to deactivate the second BWP if both the first timer and the third timer expire. That is to say, when multiple timers corresponding to the second BWP all time out, the second BWP will be deactivated; and when one of the timers corresponding to the second BWP times out, it means that there are other timers. The corresponding service data is scheduled, so the second BWP will not be deactivated.

scene 3,

The first processing unit 32 is configured to start or restart a first timer based on the first instruction when the fourth instruction is received through the first communication unit 31; wherein the first timer also corresponds to the first BWP .

In this scenario, one timer can correspond to multiple BWPs; in this solution, the first timer can correspond to the first BWP in addition to the second BWP. That is to say, when the instruction is received again (it should be pointed out that the fourth instruction may be the same as the first instruction or different from the first instruction), the first timer can be restarted or started again, and the first Activation status of BWP.

In this scenario, the fourth instruction may be used to trigger the first timer corresponding to the first BWP to restart.

There is another situation: the first processing unit 32 is configured to deactivate the first BWP and activate the third BWP at the same time if the first timer expires; wherein the third BWP is different from the first BWP . That is to say, at this time, the first timer can correspond to multiple BWPs. Therefore, when the first timer times out, it can be controlled to deactivate the first BWP and then activate the third BWP. At this time, the third BWP is different from the first BWP. In addition, since the first timer corresponds to the first BWP and the second BWP, when the first timer expires, the second BWP is also deactivated.

The first instruction includes:

RRC dedicated signaling;

Or, MAC CE;

or, DCI;

Or, a specific sequence.

The specific sequence may be a terminal-specific sequence or a common sequence of cells. The DCI is transmitted by the PDCCH scrambled by the RNTI; wherein the RNTI includes the C-RNTI, the CS-RNTI and the first RNTI.

It should be pointed out that the first RNTI refers to an RNTI that is different from the various RNTIs timed in the prior art, that is, the PDCCH is scrambled by the first RNTI, so that the receiver, that is, the terminal equipment , it is determined that the currently received command is different from the command carried by the PDCCH scrambled by other RNTIs, that is, the command that can activate multiple BWPs at the same time. Further, the first RNTI in this embodiment is used for user data scheduling, and is different from C-RNTI and CS-RNTI; in addition, the MCS table can also be distinguished by using the first RNTI.

It should also be understood that the two BWPs (the first BWP and the second BWP) in this embodiment may be two downlink BWPs, or may be two uplink BWPs; however, this embodiment may not target two BWPs A case where one is a downstream BWP and the other is an upstream BWP. Further, this application focuses on the situation of at least two downlink BWPs, but does not exclude that the timer can be applied in the scenario of at least two uplink BWPs.

It can be seen that by adopting the above solution, when the first instruction is received on the first BWP, the second BWP can be activated and the first timer corresponding to the second BWP can be started or restarted; Active at the same time.

A network device provided by an embodiment of the present application includes:

The second communication unit sends a first instruction on the first BWP of the terminal device; the first instruction is used to trigger the terminal device to start or restart the first timer and activate the second BWP;

Wherein, the first BWP is the BWP currently in the active state of the terminal device; the first timer corresponds to the second BWP.

The aforementioned first BWP and the second BWP are configured on the same carrier or on different carriers.

It should be pointed out that the BWP in the active state described in this embodiment may also include the initial BWP (initial BWP) in the idle state; for example, the terminal receives on the initial BWP (that is, the first BWP in the idle state) The first command activates the second BWP.

Here, the first instruction is used to trigger the terminal device to start or restart the first timer and activate the second BWP, which can be understood as being used to maintain the activation state of the initial BWP.

In addition, the first BWP here may be the initial BWP, and may not be the BWP configured in the connected state; the aforementioned second BWP may be configured in the connected state.

There is a scenario in this embodiment that: when a first instruction is received on the first BWP, the first BWP is kept in an activated state. That is to say, at this time, it can be ensured that the first BWP and the second BWP are in an active state at the same time, which ensures that at least two BWPs can be in an active state at the same time.

Based on the foregoing solutions, various scenarios provided by this embodiment are introduced below:

scene 1,

A second timer is started or restarted; wherein the second timer corresponds to the first BWP.

That is to say, in this scenario, each BWP corresponds to a timer; that is, the first timer corresponds to the second BWP, and the second timing corresponds to the first BWP.

It should be noted that, in this embodiment, the second timer corresponds to the first BWP, which means that the second timer is used to time the operation of scheduling data in the first BWP.

Correspondingly, the second communication unit sends a second instruction on the second BWP of the terminal device, and enables the terminal device to start or restart the first timer through the second instruction. That is, through the second instruction, the first timer corresponding to the second BWP can be started or restarted. It can be understood that, before the first timer is started, the second BWP may be in a deactivated state after completing data scheduling, or may be in a data scheduling state, but since the second instruction is received again, it can be Restart the first timer.

scene 2,

The second communication unit sends a third instruction on the second BWP of the terminal device, and enables the terminal device to start or restart a third timer through the second instruction; wherein, the third timer and the The second BWP corresponds to and the third timer is different from the first timer.

In this scenario, one BWP may correspond to multiple timers, multiple timers may correspond to different scheduling data respectively, and multiple timers may be started at different times or in overlapping time periods. For example, when the second BWP is performing data scheduling, it receives the third instruction again. At this time, the third timer is started while scheduling the corresponding data based on the third instruction. At this time, the second BWP simultaneously starts the third timer. A timer corresponds to the scheduling of the first service data, and a third timer is enabled to correspond to the scheduling of the second service data.

In this scenario, if both the first timer and the third timer expire, the second BWP is deactivated. That is to say, when multiple timers corresponding to the second BWP all time out, the second BWP will be deactivated; and when one of the timers corresponding to the second BWP times out, it means that there are other timers. The corresponding service data is scheduled, so the second BWP will not be deactivated.

Scenario 3: Through a fourth instruction (the fourth instruction is the same as or different from the first instruction), a first timer is started or restarted based on the first instruction; wherein, the first timer also corresponds to the first BWP.

In this scenario, the fourth instruction may be used to trigger the first timer corresponding to the first BWP to restart.

In this scenario, one timer can correspond to multiple BWPs; in this solution, the first timer can correspond to the first BWP in addition to the second BWP. That is to say, when the instruction is received again (it should be noted that the fourth instruction may be the same as the first instruction or different from the first instruction), the first timer can be restarted or started again to reactivate the first a BWP.

The first instruction includes:

RRC dedicated signaling;

Or, MAC CE;

or, DCI;

Or, a specific sequence.

The specific sequence may be a terminal-specific sequence or a common sequence of cells.

The DCI is transmitted by the PDCCH scrambled by the RNTI; wherein the RNTI includes the C-RNTI, the CS-RNTI and the first RNTI.

It should be pointed out that the first RNTI refers to an RNTI that is different from the various RNTIs timed in the prior art, that is, the PDCCH is scrambled by the first RNTI, so that the receiver, that is, the terminal equipment , it is determined that the currently received command is different from the command carried by the PDCCH scrambled by other RNTIs, that is, the command that can activate multiple BWPs at the same time. Further, the first RNTI in this embodiment is used for user data scheduling, and is different from C-RNTI and CS-RNTI; in addition, the MCS table can also be distinguished by using the first RNTI.

It should also be understood that the two BWPs (the first BWP and the second BWP) in this embodiment may be two downlink BWPs, or may be two uplink BWPs; however, this embodiment may not target two BWPs A case where one is a downstream BWP and the other is an upstream BWP. Further, this application focuses on the situation of at least two downlink BWPs, but does not exclude that the timer can be applied in the scenario of at least two uplink BWPs.

It can be seen that by adopting the above solution, when the first instruction is received on the first BWP, the second BWP can be activated and the first timer corresponding to the second BWP can be started or restarted; Active at the same time.

Further, the scheme provided by this embodiment is further described in detail in conjunction with accompanying drawings 4-8:

As shown in FIG. 4 , the UE receives the first instruction to activate the second BWP on the currently activated first BWP, and at this time, the UE activates the second BWP and maintains the activation state of the first BWP;

Timer start conditions:

When the UE activates the second BWP, it starts/restarts the second BWP timer configured by the network corresponding to the second BWP; the second BWP timer may be the first timer mentioned in the foregoing embodiment; When the second BWP is instructed, the second BWP timer is started/restarted while the second BWP is activated.

Timer timeout behavior: As shown in FIG. 5 , the second BWP timer corresponding to the second BWP times out, and the UE deactivates the second BWP; or,

As shown in FIG. 6 , when the timer corresponding to the second BWP expires, the UE deactivates the second BWP, and activates a configured third BWP. The configured third BWP is different from the second BWP; and is also different from the first BWP. different.

Figure 7 shows a scenario in which one BWP corresponds to multiple timers. In the figure, the second BWP is activated based on the first instruction received by the first BWP, and the second timer is restarted when the first instruction is received; When the BWP receives the third instruction again, it starts a third timer again; when both the first timer and the third timer expire, the second BWP is deactivated.

Figure 8 shows a scenario in which one timer corresponds to multiple BWPs; when the first BWP receives an instruction, activates the second BWP and restarts the first timer, wherein the restart of the first timing can be performed when an instruction is received, When the second BWP is activated; when the first timer expires, the first BWP and the second BWP may be deactivated, and the third BWP may be activated at the same time.
