Description

Bandwidth part activation method and related equipment

Technical Field

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

Background

The system bandwidth supported by a New wireless (NR, New Radio) system is much larger than the maximum LTE 20MHz system bandwidth, and for some terminals, due to limited capability, the system bandwidth cannot necessarily support the whole system bandwidth; to improve scheduling efficiency and from the terminal power saving point of view, NR introduces the concept of bandwidth part BWP. In the RRC connected state, the network configures one or more BWPs for the terminal, where the BWPs mainly include three parameters: numeriology: identifying a basic set of parameters, i.e. corresponding to a specific carrier spacing SCS; a central frequency point; bandwidth: less than or equal to the maximum system bandwidth.

It can be seen that BWP is a concept of frequency domain dimension. Meanwhile, in the discussion of R-15, it is assumed that the terminal supports only one active BWP at one point in time. By active, it is meant that the terminal desires to receive signals over the bandwidth specified by the BWP, including data transmissions (uplink and downlink), system messages, and so on.

Meanwhile, the existing discussion also allows the network to trigger the terminal to switch between different BWPs configured by the terminal by sending an instruction, i.e. deactivate (deactivate) the current BWP and activate a new BWP.

In the spectral enhancement claim description of R-16, a scenario has been discussed in which a terminal supports more than 1 active BWP at the same time. However, existing BWP switching mechanisms do not support scenarios where multiple BWPs are activated simultaneously.

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

step 201: receiving a first instruction on a first bandwidth portion BWP; wherein the first BWP is a BWP currently in an active state;

step 202: activating a second BWP and starting or restarting a first timer based on the first instruction; the first timer corresponds to a 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 active state described in this embodiment may also include an initial BWP (initial BWP) in an idle state; for example, the terminal receives a first command on the initial BWP (i.e., the first BWP in idle state) and activates the second BWP.

Here, this first instruction is used to trigger the terminal device to start or restart a first timer and activate a second BWP; as can be appreciated, for maintaining the active state of the initial BWP.

In addition, here, the first BWP may be an initial BWP, and may not be a BWP in which the terminal is in a connected configuration; the aforementioned second BWP may be configured in a connected state.

In this embodiment, there is a scenario that: maintaining the first BWP in an active state after receiving a first instruction on the first BWP.

That is, it can be ensured that the first BWP and the second BWP are active at the same time, so that at least two BWPs can be active at the same time.

It should be noted here that when the second BWP is deactivated, there may be the following cases, and one case is: and if the first timer is overtime, deactivating the second BWP. In this case, the first BWP may be maintained in an activated state when the second BWP is deactivated.

The other situation is as follows: deactivating the second BWP and activating a third BWP if the first timer times out; wherein the third BWP is different from the second BWP. In this case, the new BWP may be activated when the second BWP is deactivated, i.e. the third BWP; that is, when the second BWP is deactivated, the third BWP and the first BWP can be simultaneously activated, i.e., it can be ensured that two BWPs are activated at the same time.

Based on the foregoing solution, the following respectively describes a plurality of scenarios provided by this embodiment:

scene 1,

Starting or restarting a second timer; wherein the second timer corresponds to a first BWP.

That is, in this scenario, there is one timer for each BWP; that is, the first timer corresponds to the second BWP, and the second timer 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 for timing the operation of scheduling data in the first BWP.

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

I.e. each BWP restarts its corresponding timer when it receives a new command again. In the scene, when a first instruction received in a first BWP is received, a second BWP is activated and a first timer is started; when a second instruction for a second BWP is received on the second BWP, the first timer can be restarted or started, and the second BWP can also be scheduled for data transmission and reception.

Scene 2,

Starting or restarting a third timer based on a third instruction when the third instruction is received on a second BWP; wherein the third timer corresponds to the second BWP and is different from the first timer.

In this scenario, one BWP may correspond to a plurality of timers, the plurality of timers may correspond to different scheduling data, and the plurality of timers may be started at different times or within overlapping time periods. For example, when the second BWP schedules data, the second BWP receives the third instruction again, and starts the third timer while scheduling corresponding data based on the third instruction, and at this time, the second BWP starts the first timer corresponding to the scheduling of the first service data and starts the second service data corresponding to the scheduling of the third timer at the same time.

In this scenario, if both the first timer and the third timer are expired, the second BWP is deactivated. That is, when all the timers corresponding to the second BWP are overtime, the second BWP is deactivated; when one of the timers corresponding to the second BWP is overtime, it means that there is traffic data corresponding to other timers to be scheduled, and therefore the second BWP is not deactivated.

Scene 3,

When a fourth instruction is received, starting or restarting a first timer based on the fourth instruction; wherein the first timer further corresponds to a first BWP.

In this scenario, one timer can correspond to a plurality of BWPs; in this scheme, the first timer may correspond to the first BWP in addition to the second BWP. That is, when the instruction is received again (note 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 active state of the first BWP may be maintained.

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

There is also a case where: if the first timer is overtime, deactivating the first BWP and simultaneously activating a third BWP; wherein the third BWP is different from the first BWP. That is, the first timer can correspond to a plurality of BWPs at this time, and thus, it may be controlled to deactivate the first BWP and then activate the third BWP when the first timer times out. In addition, since the first timer corresponds to the first BWP and the second BWP, the second BWP is also deactivated when the first timer times out.

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

The first instructions include:

radio Resource Control (RRC) dedicated signaling;

or, a Media Access Control (MAC) Control Element (CE, Control Element);

or, Downlink Control Information (DCI);

alternatively, a specific sequence.

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

The DCI is transmitted by a Physical Downlink Control Channel (PDCCH) scrambled by a Radio Network Temporary Identity (RNTI), wherein the RNTI comprises a Cell Radio Network Temporary Identity (C-RNTI, Cell-RNTI), a CS-RNTI and a first RNTI.

It should be noted that, the first RNTI indicates an RNTI different from various RNTIs timed in the prior art, that is, the PDCCH is scrambled by the first RNTI, so that a receiving party, that is, a terminal device, can determine that a currently received instruction is different from an instruction carried by the PDCCH scrambled by another RNTI, that is, an instruction of a plurality of BWPs can be activated simultaneously. Further, the first RNTI is used for user data scheduling in this embodiment and is different from C-RNTI and CS-RNTI; in addition, the first RNTI is adopted to distinguish the MCS table.

It should be further understood that the two BWPs (the first BWP and the second BWP) in this embodiment may be two downstream BWPs, or may be two upstream BWPs; however, this embodiment may not address the case where two BWPs are one downstream BWP and the other upstream BWP. Further, the present application focuses on the case of at least two downstream BWPs, but does not exclude that the timer can be applied in the scenario of at least two upstream BWPs.

Therefore, by adopting the above scheme, when the first command is received on the first BWP, the second BWP is activated, and the first timer corresponding to the second BWP is started or restarted; thus, activation of multiple BWPs in a single period of time is achieved.

The schematic flowchart of a method for interacting terminal capability information provided by the embodiment of the 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 may be understood as being used to maintain the active state of the initial BWP.

In this embodiment, there is a scenario that: maintaining the first BWP in an active state upon receipt of a first instruction on the first BWP. That is, it can be ensured that the first BWP and the second BWP are active at the same time, so that at least two BWPs can be active at the same time.

scene 1,

Correspondingly, a second instruction is sent on a second BWP of the terminal device, and the terminal device is caused to start or restart the first timer through the second instruction. That is, the second instruction may cause the first timer corresponding to the second BWP to start or restart. It is 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, but since the second instruction is received again, the first timer may be restarted.

Scene 2,

Sending a third instruction on a second BWP of the terminal device, and enabling the terminal device to start or restart a third timer through the second instruction; wherein the third timer corresponds to the second BWP and is different from the first timer.

Scenario 3, starting or restarting a first timer based on a fourth instruction (the fourth instruction is the same as or different from the first instruction); wherein the first timer further corresponds to a first BWP. In this scenario, the fourth instruction may be configured to trigger a first timer corresponding to the first BWP to restart.

In this scenario, one timer can correspond to a plurality of BWPs; in this scheme, the first timer may correspond to the first BWP in addition to the second BWP. That is, when the instruction is received again (note 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 BWP.

The first instructions include:

RRC dedicated signaling;

alternatively, a MAC CE;

alternatively, DCI;

alternatively, a specific sequence.

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

Here, the first instruction is used to trigger the terminal device to start or restart a first timer and activate a second BWP; as can be appreciated, for maintaining the active state of the initial BWP.

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

It should be noted here that when the second BWP is deactivated, there may be the following cases, and one case is: a first processing unit 32, configured to deactivate the second BWP if the first timer times out. In this case, the first BWP may be maintained in an activated state when the second BWP is deactivated.

The other situation is as follows: a first processing unit 32, configured to deactivate the second BWP and activate the third BWP if the first timer times out; wherein the third BWP is different from the second BWP. In this case, the new BWP may be activated when the second BWP is deactivated, i.e. the third BWP; that is, when the second BWP is deactivated, the third BWP and the first BWP can be simultaneously activated, i.e., it can be ensured that two BWPs are activated at the same time.

Scene 2,

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

In this scenario, the first processing unit 32 is configured to deactivate the second BWP if the first timer and the third timer both time out. That is, when all the timers corresponding to the second BWP are overtime, the second BWP is deactivated; when one of the timers corresponding to the second BWP is overtime, it means that there is traffic data corresponding to other timers to be scheduled, and therefore the second BWP is not deactivated.

Scene 3,

That is, the first timer can correspond to a plurality of BWPs at this time, and thus, it may be controlled to deactivate the first BWP and then activate the third BWP when the first timer times out. 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, the second BWP is also deactivated when the first timer times out.

The first instructions include:

RRC dedicated signaling;

alternatively, a MAC CE;

alternatively, DCI;

alternatively, a specific sequence.
