Description

Method for activating bandwidth part and related equipment

Technical field

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

Background technique

The new wireless (NR, New Radio) system supports a system bandwidth that 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 full system bandwidth; in order to improve scheduling efficiency and save terminal resources, From the perspective of electricity, NR introduced the concept of bandwidth part BWP. In the RRC connection state, the network configures one or more BWPs for the terminal. The BWP mainly includes three parameters: Numerology: identifies the basic parameter set, that is, corresponding to a specific carrier interval SCS; the center frequency; bandwidth: less than or equal to the maximum system bandwidth.

It can be seen that BWP is a concept in the frequency domain dimension. Meanwhile, in the discussion of R-15, it is assumed that the terminal supports only one activated BWP at a point in time. 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 a terminal to switch between different BWPs configured by sending instructions, that is, to deactivate the current BWP and activate a new BWP.

In the description of the R-16's spectrum enhancement project, discussions have started on a scenario where the terminal supports more than one activated BWP at the same time. However, the existing BWP switching mechanism does not support scenarios in which multiple BWPs are activated simultaneously.

FIG. 2 is a schematic flowchart of a BWP activation method according to an embodiment of the present application, which is applied to a terminal device and includes:

Step 201: Receive a first instruction on a first bandwidth part BWP, where the first BWP is a BWP that is currently in an activated state;

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

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

It should be noted that the BWP in the activated state described in this embodiment may also include an 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 instruction activates the second BWP.

Here, this 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 an initial BWP and may not be a BWP configured in a connected state of the terminal; the foregoing second BWP may be configured in a connected state.

In this embodiment, there is a scenario in which, after receiving a first instruction 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 activated at the same time, so that at least two BWPs can be activated at the same time.

It should be noted here that when the second BWP is deactivated, the following situations may exist. One case is that if the first timer expires, 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 case is: if the first timer expires, deactivate the second BWP and activate the third BWP; wherein the third BWP is different from the second BWP. In this case, when the second BWP is deactivated, a new BWP can be activated, that is, the third BWP; 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 can also be 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,

Start or restart a second timer; wherein the second timer corresponds to the first BWP.

That is, 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, and refers to the second timer used to time the operation of scheduling data in the first BWP.

Accordingly, when a 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 instruction. In this scenario, when a first instruction is received in the first BWP, the second BWP is activated and the first timer is started; when a second instruction for the second BWP is received on the second BWP, the first BWP can be enabled. The timer is restarted or started, and the second BWP can 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 can correspond to multiple timers, multiple timers can correspond to different scheduling data, and multiple timers can be started at different times or can be started in overlapping time periods. For example, when the second BWP is performing data scheduling, it receives a third instruction again. At this time, the third timer is started while the corresponding data is scheduled based on the third instruction. At this time, the second BWP starts the first One timer corresponds to scheduling the first service data, and the second service data corresponding to scheduling of the third timer is enabled.

In this scenario, if both the first timer and the third timer expire, the second BWP is deactivated. In other words, the second BWP will be deactivated when multiple timers corresponding to the second BWP have timed out, and when one of the timers corresponding to the second BWP expires, it means that there are other timers The corresponding service data is scheduled, so the second BWP is not deactivated.

Scenario 3.

When a fourth instruction is received, a 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, 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 may be restarted or started again, and the first instruction is maintained. BWP activation status.

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

There is another case: if the first timer expires, the first BWP is deactivated and the third BWP is activated; wherein the third BWP is different from the first BWP. That is, at this time, the first timer can correspond to multiple BWPs. Therefore, when the first timer expires, 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, media access control (MAC, Media Access Control) control element (CE, Control element);

Or, downlink control information (DCI, Downlink Control Information);

Or, a specific sequence.

The specific sequence may be a terminal-specific sequence or a sequence common to a cell.

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

It should be noted that the first RNTI refers to an RNTI that is different from various RNTIs timing in the prior art, that is, the first RNTI is used to scramble the PDCCH to enable the receiver, that is, the terminal device It is determined that the currently received instruction is different from the instruction carried by the PDCCH scrambled by other RNTIs, that is, the instruction capable of simultaneously activating multiple BWPs. Further, the first RNTI described in this embodiment is used for user data scheduling, and is different from C-RNTI and CS-RNTI; in addition, the first RNTI can also be used to distinguish the MCS table.

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. One is the case of downlink BWP and the other is uplink BWP. Further, this application focuses on the case 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 scheme, 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 at the same time; Activated at the same time.

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

Here, this 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 maintaining the activated state of the initial BWP.

There is a scenario in this embodiment: 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 activated at the same time, so that at least two BWPs can be activated at the same time.

scene 1,

Correspondingly, a second instruction is sent on a second BWP of the terminal device, and the second instruction is used to enable the terminal device to start or restart a first timer. That is, by using 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 the data scheduling, or may be in a data scheduling state for the second BWP, but since the second instruction is received again, it may be in the Restart the first timer.

Scene 2,

Sending a third instruction on the second BWP of the terminal device, and using the second instruction to cause 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.

Scenario 3: Use a fourth instruction (the fourth instruction is the same as or different from the first instruction) to start or restart the first timer 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, 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 may be restarted or started again to reactivate the first instruction. A BWP.

The first instruction includes:

RRC-specific signaling;

Or MAC CE;

Or DCI;

Or, a specific sequence.

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

It should be noted that the first RNTI refers to an RNTI that is different from various RNTIs timing in the prior art, that is, the first RNTI is used to scramble the PDCCH to enable the receiver, that is, the terminal device. It is determined that the currently received instruction is different from the instruction carried by the PDCCH scrambled by other RNTIs, that is, the instruction capable of simultaneously activating multiple BWPs. Further, the first RNTI described in this embodiment is used for user data scheduling, and is different from C-RNTI and CS-RNTI; in addition, the first RNTI can also be used to distinguish the MCS table.

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

FIG. 3 is a terminal device according to an embodiment of the present application, including:

The first communication unit 31 is configured to receive a first instruction on a first bandwidth part BWP, where the first BWP is a BWP that is currently in an activated state;

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

In this embodiment, a scenario is as follows: a first processing unit 32 is configured to keep the first BWP in an activated state after receiving a first instruction on the first BWP.

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

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

scene 1,

The first processing unit 32 is configured to start or restart a second timer, where the second timer corresponds to a 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 instruction. In this scenario, when a first instruction is received in the first BWP, the second BWP is activated and the first timer is started; when a second instruction for the second BWP is received on the second BWP, the first BWP can be made The timer is restarted or started, and the second BWP can also be scheduled to send and receive data.

Scene 2,

A first processing unit 32, 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, the first processing unit 32 is configured to deactivate the second BWP if both the first timer and the third timer expire. In other words, the second BWP will be deactivated when multiple timers corresponding to the second BWP have timed out, and when one of the timers corresponding to the second BWP expires, it means that there are other timers The corresponding service data is scheduled, so the second BWP is not deactivated.

Scenario 3.

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

There is another case: a first processing unit 32 is configured to deactivate the first BWP and activate a third BWP at the same time if the first timer times out; wherein the third BWP is different from the first BWP . That is, at this time, the first timer can correspond to multiple BWPs. Therefore, when the first timer expires, 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-specific signaling;

Or MAC CE;

Or DCI;

Or, a specific sequence.

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

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

scene 1,

Correspondingly, the second communication unit sends a second instruction on the second BWP of the terminal device, and causes the terminal device to start or restart the first timer by using the second instruction. That is, by using 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 the data scheduling, or may be in a data scheduling state for the second BWP, but since the second instruction is received again, it may be in the Restart the first timer.

Scene 2,

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

Scenario 3: Use a fourth instruction (the fourth instruction is the same as or different from the first instruction) to start or restart the first timer based on the first instruction; wherein the first timer also corresponds to the first BWP.

The first instruction includes:

RRC-specific signaling;

Or MAC CE;

Or DCI;

Or, a specific sequence.

Further, the solution provided in this embodiment will be further described in detail with reference to FIGS. 4-8:

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.

In the figure, the second BWP is activated based on the first instruction received by the first BWP, and the second timer restarts 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.

FIG. 8 illustrates a scenario in which one timer corresponds to multiple BWPs. When the first BWP receives an instruction, the second BWP is activated and the first timer is restarted, where the restart at the first timing can be performed when the instruction is received.
