Description

Method for starting and configuring bandwidth section and terminal equipment

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

The system bandwidth supported by New Radio (NR) is much greater than the maximum 20MHz system bandwidth of LTE (Long Term Evolution). For some terminals, due to limited capabilities, it may not be able to support all system frequencies. Wide; in order to improve scheduling efficiency and from the perspective of terminal power saving, NR introduced the concept of bandwidth part BWP. In the radio resource control (RRC, Radio Resource Control) connection state, the network configures one or more BWPs for the terminal.

It can be seen from this that BWP is a concept of frequency domain dimension. At the same time, in the discussion of R-15, it is assumed that at a point in time, the terminal supports only one activated 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 information, and so on.

However, the timer-based BWP switching mechanism does not support the scenario where multiple BWPs are started at the same time, so a new timer mechanism needs to be designed to support multiple BWPs started simultaneously.

To solve the above technical problems, embodiments of the present invention provide a method for starting and configuring a bandwidth part (BWP, Bandwidth Part), a terminal device, a chip, a computer-readable storage medium, a computer program product, and a computer program, so that the terminal side can Support to activate at least two BWP at the same time.

In a second aspect, a terminal device is provided, including:

A communication unit, in the first control resource set and the first search space configured on the first bandwidth part BWP, detecting a start instruction for at least one second BWP; wherein, the first BWP is in a start state, the at least A second BWP is in a deactivated state;

The processing unit, when detecting a start instruction for at least one second BWP, starts the at least one second BWP.

In some embodiments of the second aspect, the communication unit blindly detects the PDCCH through the first control resource set corresponding to the first BWP to detect a start instruction for at least one second BWP.

2 is a schematic flowchart of a method for starting and configuring a BWP provided by an embodiment of the present application, which is applied to a terminal device and includes:

Step 201: In the first control resource set and the first search space configured on the first bandwidth part BWP, detect a start instruction for at least one second BWP; wherein, the first BWP is in a start state, the at least A second BWP is in a deactivated state;

Step 202: When a start instruction for at least one second BWP is detected, start the at least one second BWP.

It should be pointed out that the BWP in the startup state described in this embodiment may also include an initial BWP in an idle state (initial BWP). In addition, here, the first BWP may not be a BWP configured in a connected state; the foregoing second BWP may be configured in a connected state.

In other words, the network configures at least two BWPs for the connected terminal devices. It can be considered that the initial BWP is also a type of BWP configured. For example, a BWP is configured in the connected network, and the initial BWP is kept in the activated state while the other configured BWPs are activated. BWP.

Further, this embodiment also includes:

Configure a control resource set and a search space corresponding to all BWPs on some BWPs of the configured at least two BWPs;

Wherein, the partial BWP includes a first BWP and does not include a second BWP; the first BWP is configured with a first control resource set (first CORESET) and a first search space (first search space), And a second control resource set and/or a second search space corresponding to the second BWP are also configured in the first BWP.

That is, at least two sets of CORESET control resources are configured on the first BWP, where the first CORESET is mapped to the first BWP and the second CORESET is mapped to the second BWP.

Only the second search space may be configured in the first BWP; the second search space corresponds to the first control resource set. Of course, it is also possible to configure both the second search space and the second set of control resources.

That is to say, there may be multiple control resource sets and search controls, for example: multiple control resource sets may be configured on the first BWP, and each control resource set may correspond to multiple search controls;

Different search spaces in the same set of control resources can correspond to different BWPs or the same BWP;

Different control resource sets may also correspond to different BWPs. For example, the first control resource set and the second control resource set are configured on the first BWP. The first control resource set may be configured to correspond to the first BWP, and the second control resource set may correspond to the second BWP.

In addition, one BWP can start multiple BWPs, one of which can be the aforementioned first BWP, and the multiple BWPs can be multiple second BWPs that are activated by the first BWP.

It should be understood that multiple second BWPs are only used to describe BWPs started by other BWPs, and the configuration of each second BWP may be the same or different, and will not be described in detail. Correspondingly, in the foregoing, among the startup instructions for at least one second BWP, the startup instruction may be a startup instruction for one BWP or a startup instruction for multiple BWPs, which will be activated by the startup instruction in this embodiment The one or more BWP are called the second BWP.

Of course, in this embodiment, the second control resource set and/or the second search space may also be configured in the second BWP, but it will not be repeated here.

The method further includes: when the at least one second BWP is in an activated state, data transmission and/or reception can be performed on the at least one second BWP, and at the same time, detection of the corresponding at least one second BWP on the first BWP Second BWP second control resource set and/or second search space.

It should be pointed out that when the second BWP is in the startup state, the data transmission and reception are not necessarily carried out. When the second BWP is in the startup state and the schedule is received, the data will be carried out on the second BWP Receive or send.

When the at least one second BWP is in the deactivated state, the second control resource set and/or the second search space corresponding to the at least one second BWP configured in the first BWP are in the deactivated state.

The starting of the second BWP further includes: starting a related channel or signal corresponding to the at least one second BWP. The start of the second BWP may also include the start of related channels/signals that are associated with it; when the second BWP is started, all or part of the search space corresponding to CORESET2 that is associated with it is started.

Wherein, the relevant signal corresponding to the second BWP may include a PDCCH control signal; the relevant signal corresponding to the second BWP may be a reference signal, for example, CRS, DMRS, etc.

When the second BWP is started, the method further includes: starting at least one second control resource set and/or a second search space configured in the first BWP corresponding to the at least one second BWP. Specifically, when the first BWP is in the activated state and (at least one) the second BWP is in the deactivated state, the CORESET corresponding to the first BWP is in the “activated” state, that is, the UE needs to blindly pick up according to the configuration of the search space Control channel on CORESET; the second CORESET and/or search space corresponding to the second BWP in the first BWP is in the "de-start" state, that is, the UE does not need to blindly pick up the control channel on CORESET2.

Starting the second control resource set and/or the second search space corresponding to the second BWP configured in the first BWP may be starting the second control resource set and the second search space together; or, only starting A certain set of control resources, but the search control preset corresponding to this set of control resources is started; or a certain search space is started, and the set of control resources corresponding to the search space has been started.

Based on the foregoing solution, the following specifically explains how to start and de-start the second BWP:

The detection of the start instruction for at least one second BWP includes:

The PDCCH is blindly detected by the first control resource set corresponding to the first BWP to detect a start instruction for at least one second BWP.

The terminal device receives an instruction to start the second BWP. The instruction may be a PDCCH blindly picked up on the corresponding first CORESET on the currently started first BWP.

The PDCCH is scrambled by the first RNTI. It should be noted that the first RNTI refers to an RNTI that is different from the various RNTIs defined in the prior art, that is, scrambling the PDCCH by the first RNTI can enable the receiver, that is, the terminal device, to determine The currently received start command is different from the command carried by the PDCCH scrambled by other RNTI. 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 distinguish the MCS table.

When at least one second BWP is started, a timer corresponding to at least one second BWP is started or restarted. Correspondingly, if the timer corresponding to the at least one second BWP has not expired, the first control resource set configured to have a corresponding relationship with the first BWP on the first BWP and the corresponding relationship with the at least one second BWP are detected The second set of control resources.

It should be understood that each started second BWP may correspond to a different timer. Of course, multiple BWPs may also correspond to a timer, which is not described in detail in this embodiment.

Detection is configured on the first BWP, a first control resource set corresponding to the first BWP, and a different search space corresponding to the first control resource set; and detection is configured on at least one second BWP, and at least one The second BWP includes at least one second control resource set corresponding to the relationship, and different search spaces corresponding to the second control resource set.

That is, during the operation of the timer, the terminal monitors the CORESET (the period configured according to the search space) corresponding to the second BWP configured on the first BWP. For example, it may be different search spaces corresponding to CORESET.

When a data schedule for at least one second BWP is detected in the second control resource set, a timer corresponding to the at least one second BWP is restarted or started. That is, if the second BWP data schedule is monitored on the second CORESET corresponding to a certain started second BWP (according to the period of the corresponding search space), the timer corresponding to the second BWP is started\restarted.

When the timer corresponding to the second BWP expires, the second BWP is started, and the second control resource set corresponding to the second BWP configured on the first BWP is not blindly detected. When the timer corresponding to BWP-2 expires, the UE starts BWP-2, and no longer blindly picks up the second CORESET configured on BWP-1 corresponding to BWP-2.

Referring to FIG. 3, a first control resource set and a second control resource set are configured on the first BWP. When a start instruction for the second BWP is received on the first control resource set, the control starts the second BWP and starts the second BWP starts the timer of the second BWP at the same time; when the timing of the second BWP expires, it stops detecting the second control resource set corresponding to the second BWP configured on the first BWP. As shown in the figure, the second control resource After the timer of the second BWP expires, the test is no longer performed.

Referring to FIG. 4, a control resource set (such as the first control resource set in the figure) includes a control resource set for the first BWP and a control resource set for the second BWP; when the first control resource is for the first BWP When the start command for the second BWP is received on the set, the second BWP is controlled to start, and the timer of the second BWP is started at the same time when the second BWP is started; when the timing of the second BWP expires, it stops detecting the configuration on the first BWP The set of control resources corresponding to the second BWP.

It can be seen that by adopting the above solution, a control resource set for at least one second BWP can be configured on one BWP and when a start instruction for at least one second BWP is detected in the search space, the control can start at least one second BWP; , To achieve the support of multiple activated BWP at the same time.

FIG. 5 is a terminal device provided by an embodiment of this application, including: The communication unit 51, in the first control resource set and the first search space configured on the first bandwidth part BWP, detects a startup instruction for at least one second BWP; wherein, the first BWP is in a startup state, the At least one second BWP is in a deactivated state;

The processing unit 52, when detecting a start instruction for at least one second BWP, starts the at least one second BWP.

It should be pointed out that the BWP in the startup state described in this embodiment may also include an initial BWP in an idle state (initial BWP). In addition, here, the first BWP may not be a BWP configured in a connected state; the foregoing second BWP may be configured in a connected state.

In other words, the network configures at least two BWPs for the connected terminal devices. It can be considered that the initial BWP is also a type of BWP configured. For example, a BWP is configured in the connected network, and the initial BWP is kept in the activated state while the other configured BWPs are activated. BWP.

Further, this embodiment also includes:

The processing unit 52 configures a control resource set and a search space corresponding to all BWPs on some BWPs of the at least two BWPs that are configured;

Wherein, the partial BWP includes a first BWP and does not include a second BWP; the first BWP is configured with a first control resource set (first CORESET) and a first search space (first search space), And a second control resource set and/or a second search space corresponding to the second BWP are also configured in the first BWP.

That is, at least two sets of CORESET control resources are configured on the first BWP, where the first CORESET is mapped to the first BWP and the second CORESET is mapped to the second BWP.

Only the second search space may be configured in the first BWP; the second search space corresponds to the first control resource set. Of course, it is also possible to configure both the second search space and the second set of control resources.

That is to say, there may be multiple control resource sets and search controls, for example: multiple control resource sets may be configured on the first BWP, and each control resource set may correspond to multiple search controls;

Different search spaces in the same set of control resources can correspond to different BWPs or the same BWP;

Different control resource sets may also correspond to different BWPs. For example, the first control resource set and the second control resource set are configured on the first BWP. The first control resource set may be configured to correspond to the first BWP, and the second control resource set may correspond to the second BWP.

In addition, one BWP can start multiple BWPs, one of which can be the aforementioned first BWP, and the multiple BWPs can be multiple second BWPs that are activated by the first BWP.

It should be understood that multiple second BWPs are only used to describe BWPs started by other BWPs, and the configuration of each second BWP may be the same or different, and will not be described in detail. Correspondingly, in the foregoing, among the startup instructions for at least one second BWP, the startup instruction may be a startup instruction for one BWP or a startup instruction for multiple BWPs, which will be activated by the startup instruction in this embodiment The one or more BWP are called the second BWP.

Of course, in this embodiment, the second control resource set and/or the second search space may also be configured in the second BWP, but it will not be repeated here.

The processing unit 52 is configured to be able to send and/or receive data on the at least one second BWP when the at least one second BWP is in an activated state, and simultaneously detect the corresponding at least one second BWP on the first BWP Second BWP second control resource set and/or second search space.

It should be pointed out that when the second BWP is in the startup state, the data transmission and reception are not necessarily carried out. When the second BWP is in the startup state and the schedule is received, the data will be carried out on the second BWP Receive or send.

The processing unit 52 is configured to, when the at least one second BWP is in a deactivated state, the second control resource set and/or the second search space corresponding to the at least one second BWP configured in the first BWP are in Go to startup state.

The processing unit 52 is configured to start a related channel or signal corresponding to the at least one second BWP. The start of the second BWP may also include the start of related channels/signals that are associated with it; when the second BWP is started, all or part of the search space corresponding to CORESET2 that is associated with it is started.

Wherein, the relevant signal corresponding to the second BWP may include a PDCCH control signal; the relevant signal corresponding to the second BWP may be a reference signal, for example, CRS, DMRS, etc.

When the second BWP is started, the processing unit 52 is configured to start at least one second control resource set and/or a second search space corresponding to the at least one second BWP configured in the first BWP. Specifically, when the first BWP is in the activated state and (at least one) the second BWP is in the deactivated state, the CORESET corresponding to the first BWP is in the “activated” state, that is, the UE needs to blindly pick up according to the configuration of the search space Control channel on CORESET; the second CORESET and/or search space corresponding to the second BWP in the first BWP is in the "de-start" state, that is, the UE does not need to blindly pick up the control channel on CORESET2.

Starting the second control resource set and/or the second search space corresponding to the second BWP configured in the first BWP may be starting the second control resource set and the second search space together; or, only starting A certain set of control resources, but the search control preset corresponding to this set of control resources is started; or a certain search space is started, and the set of control resources corresponding to the search space has been started.

Based on the foregoing solution, the following specifically explains how to start and de-start the second BWP:

The communication unit 51 blindly detects the PDCCH through the first control resource set corresponding to the first BWP to detect a start instruction for at least one second BWP.

The instruction may be a PDCCH blindly picked up on the corresponding first CORESET on the currently activated first BWP.

The PDCCH is scrambled by the first RNTI. It should be noted that the first RNTI refers to an RNTI that is different from the various RNTIs defined in the prior art, that is, scrambling the PDCCH by the first RNTI can enable the receiver, that is, the terminal device, to determine The currently received start command is different from the command carried by the PDCCH scrambled by other RNTI. 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 distinguish the MCS table.

When at least one second BWP is started, a timer corresponding to at least one second BWP is started or restarted. Correspondingly, if the timer corresponding to the at least one second BWP has not expired, the first control resource set configured to have a corresponding relationship with the first BWP on the first BWP and the corresponding relationship with the at least one second BWP are detected The second set of control resources.

It should be understood that each started second BWP may correspond to a different timer. Of course, multiple BWPs may also correspond to a timer, which is not described in detail in this embodiment.

Detection is configured on the first BWP, a first control resource set corresponding to the first BWP, and a different search space corresponding to the first control resource set; and detection is configured on at least one second BWP, and at least one The second BWP includes at least one second control resource set corresponding to the relationship, and different search spaces corresponding to the second control resource set.

That is, during the operation of the timer, the terminal monitors the CORESET (the period configured according to the search space) corresponding to the second BWP configured on the first BWP. For example, it may be different search spaces corresponding to CORESET.

When a data schedule for at least one second BWP is detected in the second control resource set, a timer corresponding to the at least one second BWP is restarted or started. That is, if the second BWP data schedule is monitored on the second CORESET corresponding to a certain started second BWP (according to the period of the corresponding search space), the timer corresponding to the second BWP is started\restarted.

The processing unit 52, when the timer corresponding to the second BWP times out, starts the second BWP and does not blindly detect the second control resource set corresponding to the second BWP configured on the first BWP. When the timer corresponding to BWP-2 expires, the UE starts BWP-2, and no longer blindly picks up the second CORESET configured on BWP-1 corresponding to BWP-2.

Referring to FIG. 3, a first control resource set and a second control resource set are configured on the first BWP. When a start instruction for the second BWP is received on the first control resource set, the control starts the second BWP and starts the second BWP starts the timer of the second BWP at the same time; when the timing of the second BWP expires, it stops detecting the second control resource set corresponding to the second BWP configured on the first BWP. As shown in the figure, the second control resource After the timer of the second BWP expires, the test is no longer performed.

Referring to FIG. 4, a control resource set (such as the first control resource set in the figure) includes a control resource set for the first BWP and a control resource set for the second BWP; when the first control resource is for the first BWP When the start command for the second BWP is received on the set, the second BWP is controlled to start, and the timer of the second BWP is started at the same time when the second BWP is started; when the timing of the second BWP expires, it stops detecting the configuration on the first BWP The set of control resources corresponding to the second BWP.

It can be seen that by adopting the above solution, a control resource set for at least one second BWP can be configured on one BWP and when a start instruction for at least one second BWP is detected in the search space, the control can start at least one second BWP; , To achieve the support of multiple activated BWP at the same time.
