Description

Bandwidth part activation and configuration method and terminal equipment
Technical Field
The present invention relates to the field of information processing technology, and in particular, to a method for activating and configuring a Bandwidth Part (BWP), a terminal device, a chip, a computer-readable storage medium, a computer program product, and a computer program.
Background
The system bandwidth supported by New Radio (NR) is much larger than the maximum system bandwidth of 20MHz of LTE (Long Term Evolution), and for some terminals, due to limited capability, the system bandwidth may not support all the system bandwidths; to improve scheduling efficiency and from the terminal power saving point of view, NR introduces the concept of bandwidth part BWP. In a Radio Resource Control (RRC) connected state, the network configures one or more BWPs to the terminal. 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.
However, a timer-based (timer) BWP switching mechanism does not support a scenario in which multiple BWPs are simultaneously activated, and thus a new timer mechanism needs to be designed to support multiple BWPs simultaneously activated.

Fig. 2 is a schematic flowchart of a BWP activation and configuration method provided in an embodiment of the present application, and the method is applied to a terminal device, and includes:
step 201: detecting, in a first set of control resources configured on a first bandwidth part BWP and in a first search space, an activation instruction for at least one second BWP; wherein the first BWP is in an activated state and the at least one second BWP is in a deactivated state;
step 202: activating at least one second BWP when an activation instruction for the at least one second BWP is detected.
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. In addition, here, the first BWP may not be the BWP in which the terminal is in the connected state configuration; the aforementioned second BWP may be configured in a connected state.
That is, the network configures at least two BWPs for the connected terminal device, and it can be considered that the initial BWP is also one of the configured BWPs, for example, configuring one BWP in the connected network, and maintaining the active state of the initial BWP while activating the other configured BWPs.
Further, this embodiment further includes:
configuring a control resource set and a search space corresponding to all the BWPs on a part of at least two configured BWPs;
wherein the partial BWP comprises a first BWP and does not comprise a second BWP; the first BWP is configured with a first control resource set (first core set) and a first Search Space (first Search Space), and the first BWP is also configured with a second control resource set and/or a second Search Space corresponding to the second BWP.
That is, at least two CORESET control resource sets are configured on the first BWP, wherein 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 at the first BWP; the second search space corresponds to the first set of control resources. It is of course also possible to configure both the second search space and the second set of control resources.
That is, the set of control resources and the search control may be multiple, such as: a plurality of control resource sets can be configured on the first BWP, and each control resource set can correspond to a plurality of search controls;
different search spaces in the same control resource set may correspond to different BWPs, or may correspond to the same BWP;
different sets of control resources may also correspond to different BWPs, for example, a first set of control resources and a second set of control resources may be configured on a first BWP, and the first set of control resources may be configured to correspond to the first BWP and the second set of control resources may correspond to the second BWP.
In addition, one BWP may activate a plurality of BWPs, where one BWP may be the aforementioned first BWP, and the plurality of BWPs may be a plurality of second BWPs activated by the first BWP.
It should be understood that the plurality of second BWPs are only used for describing BWPs activated by other BWPs, and the configuration of each second BWP may be the same or different, and will not be described again. Accordingly, in the foregoing, the activation instruction for at least one second BWP may be an activation instruction for one BWP, or may also be an activation instruction for multiple BWPs, and in this embodiment, the one or more BWPs activated by the activation instruction are all referred to as second BWPs.
Of course, in this embodiment, the second BWP may also be configured with the second control resource set and/or the second search space, which is not described again.
The method further comprises the following steps: when the at least one second BWP is in the active state, data transmission and/or reception can be performed on the at least one second BWP while a second set of control resources and/or a second search space corresponding to the at least one second BWP is detected on the first BWP.
It should be noted that when the second BWP is in the active state, data is not necessarily transmitted and received, and when the second BWP is in the active state and receives the schedule, data is not received or transmitted on the second BWP.
When the at least one second BWP is in a deactivated state, a second set of control resources and/or a second search space configured in the first BWP corresponding to the at least one second BWP is in a deactivated state.
The activation of the second BWP further comprises: activating a correlation channel or signal corresponding to the at least one second BWP. Activation of the second BWP may also include activation of the associated channel/signal with which it has an association relationship; when the second BWP is activated, all or part of the search space corresponding to the core set2 with association relationship is activated.
Wherein, the related signal corresponding to the second BWP may include a physical downlink control channel PDCCH control signal; the related signal corresponding to the second BWP may be a reference signal, for example, a cell reference signal CRS, a demodulation reference signal DMRS, or the like.
The method further comprises, while the second BWP is active: activating at least one second set of control resources 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 active state, and the (at least one) second BWP is in the inactive state, the core set corresponding to the first BWP is in the "active" state, that is, the UE needs to blindly pick up the control channel on the core set according to the configuration of the search space; the second CORESET and/or search space in the first BWP corresponding to the second BWP is in the "deactivated" state, i.e., the UE does not need to blindly pick up the control channel on CORESET 2.
Activating a second set of control resources and/or a second search space configured in the first BWP corresponding to the second BWP may be activating the second set of control resources and the second search space together; or only activating a certain specific control resource set, but the search control corresponding to the control resource set is activated by default; or activating a certain search space, wherein the control resource set corresponding to the search space is already activated.
Based on the foregoing scheme, how to perform the activation and deactivation process of the second BWP is specifically described below:
the detecting of the activation instruction for the at least one second BWP comprises:
blindly detecting a PDCCH through a first control resource set corresponding to a first BWP to detect an activation instruction for at least one second BWP.
The terminal device receives an instruction to activate the second BWP, which may be a PDCCH blindly picked up on the first CORESET with a correspondence on the currently activated first BWP.
The PDCCH is scrambled by a first Radio Network Temporary Identity (RNTI). It should be noted that, the first RNTI indicates an RNTI different from various RNTIs defined 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 activation instruction is different from an instruction carried by the PDCCH scrambled by another RNTI. Further, in this embodiment, the first RNTI is used for user data scheduling, and is different from a cell-radio network temporary identity (C-RNTI), a radio network temporary identity (CS-RNTI) configured for scheduling; in addition, the first RNTI is used to distinguish a Modulation and Coding Scheme (MCS) table.
When the at least one second BWP is activated, a timer corresponding to the at least one second BWP is started or restarted. Accordingly, if the timer corresponding to the at least one second BWP is not expired, a first control resource set corresponding to the first BWP and a second control resource set corresponding to the at least one second BWP configured on the first BWP are detected.
It should be understood that each activated second BWP may correspond to a different timer, and certainly, multiple BWPs may also correspond to a timer, which is not described in detail in this embodiment.
Detecting a first control resource set which is configured on a first BWP and has a corresponding relation with the first BWP and a different search space corresponding to the first control resource set; and detecting at least one second control resource set arranged on the at least one second BWP and having a correspondence with the at least one second BWP, and a different search space corresponding to the second control resource set.
That is, during the timer running, the terminal monitors the CORESET (configured according to the search space) configured on the first BWP in correspondence with the second BWP. For example, it may be different search spaces corresponding to CORESET.
Restarting or starting a timer corresponding to at least one second BWP when a data schedule for the at least one second BWP is detected at the second set of control resources. That is, if the second BWP data scheduling is monitored on the second core set corresponding to a certain activated second BWP (according to the period of the corresponding search space), the timer corresponding to the second BWP is started \ restarted.
Deactivating a second BWP when a timer corresponding to the second BWP expires, without blindly detecting a second set of control resources corresponding to the second BWP configured on the first BWP. When the timer corresponding to BWP-2 times out, the UE deactivates 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 set of control resources and a second set of control resources are configured on a first BWP, and when an activation instruction for the second BWP is received on the first set of control resources, the first BWP is controlled to be activated, and a timer of the second BWP is started while the second BWP is activated; when the timer of the second BWP expires, stopping detecting the second control resource set corresponding to the second BWP configured on the first BWP, and as shown in the figure, the second control resource set does not perform detection any more after the timer of the second BWP expires.
Referring to fig. 4, one control resource set (such as the first control resource set in the figure) has a control resource set for the first BWP and a control resource set for the second BWP; when an activation instruction for a second BWP is received on a first set of control resources for a first BWP, controlling activation of the second BWP, starting a timer for the second BWP while the second BWP is activated; and when the timing of the second BWP is overtime, stopping detecting the control resource set corresponding to the second BWP configured on the first BWP.
It can be seen that, by adopting the above scheme, when a set of control resources for at least one second BWP is configured on one BWP and an activation instruction for the at least one second BWP is detected on the search space, the at least one second BWP is controlled to be activated; in this way, a BWP scenario is achieved that supports multiple activations at the same time.
Fig. 5 is a terminal device provided in an embodiment of the present application, including:
a communication unit 51 that detects an activation instruction for at least one second bandwidth part BWP in a first set of control resources configured on the first BWP and a first search space; wherein the first BWP is in an activated state and the at least one second BWP is in a deactivated state;
the processing unit 52, when detecting an activation instruction for at least one second BWP, activates the at least one second BWP.
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. In addition, here, the first BWP may not be the BWP in which the terminal is in the connected state configuration; the aforementioned second BWP may be configured in a connected state.
That is, the network configures at least two BWPs for the connected terminal device, and it can be considered that the initial BWP is also one of the configured BWPs, for example, configuring one BWP in the connected network, and maintaining the active state of the initial BWP while activating the other configured BWPs.
Further, this embodiment further includes:
a processing unit 52, configured to configure a control resource set and a search space corresponding to all BWPs on a part of the at least two configured BWPs;
wherein the partial BWP comprises a first BWP and does not comprise a second BWP; the first BWP is configured with a first control resource set (first core set) and a first Search Space (first Search Space), and the first BWP is also configured with a second control resource set and/or a second Search Space corresponding to the second BWP.
That is, at least two CORESET control resource sets are configured on the first BWP, wherein 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 at the first BWP; the second search space corresponds to the first set of control resources. It is of course also possible to configure both the second search space and the second set of control resources.
That is, the set of control resources and the search control may be multiple, such as: a plurality of control resource sets can be configured on the first BWP, and each control resource set can correspond to a plurality of search controls;
different search spaces in the same control resource set may correspond to different BWPs, or may correspond to the same BWP;
different sets of control resources may also correspond to different BWPs, for example, a first set of control resources and a second set of control resources may be configured on a first BWP, and the first set of control resources may be configured to correspond to the first BWP and the second set of control resources may correspond to the second BWP.
In addition, one BWP may activate a plurality of BWPs, where one BWP may be the aforementioned first BWP, and the plurality of BWPs may be a plurality of second BWPs activated by the first BWP.
It should be understood that the plurality of second BWPs are only used for describing BWPs activated by other BWPs, and the configuration of each second BWP may be the same or different, and will not be described again. Accordingly, in the foregoing, the activation instruction for at least one second BWP may be an activation instruction for one BWP, or may also be an activation instruction for multiple BWPs, and in this embodiment, the one or more BWPs activated by the activation instruction are all referred to as second BWPs.
Of course, in this embodiment, the second BWP may also be configured with the second control resource set and/or the second search space, which is not described again.
A processing unit 52 configured to enable data transmission and/or reception on the at least one second BWP while detecting a second set of control resources and/or a second search space corresponding to the at least one second BWP on the first BWP when the at least one second BWP is in an active state.
It should be noted that when the second BWP is in the active state, data is not necessarily transmitted and received, and when the second BWP is in the active state and receives the schedule, data is not received or transmitted on the second BWP.
A processing unit 52, configured to, when the at least one second BWP is in a deactivated state, deactivate a second set of control resources and/or a second search space configured in the first BWP and corresponding to the at least one second BWP.
A processing unit 52 for activating a relevant channel or signal corresponding to the at least one second BWP. Activation of the second BWP may also include activation of the associated channel/signal with which it has an association relationship; when the second BWP is activated, all or part of the search space corresponding to the core set2 with association relationship is activated.
Wherein, the related signal corresponding to the second BWP may include a PDCCH control signal; the related signal corresponding to the second BWP may be a reference signal, for example, CRS, DMRS, or the like.
When the second BWP is activated, the processing unit 52 is configured to activate at least one second control resource set and/or a second search space configured in the first BWP and corresponding to the at least one second BWP. Specifically, when the first BWP is in the active state, and the (at least one) second BWP is in the inactive state, the core set corresponding to the first BWP is in the "active" state, that is, the UE needs to blindly pick up the control channel on the core set according to the configuration of the search space; the second CORESET and/or search space in the first BWP corresponding to the second BWP is in the "deactivated" state, i.e., the UE does not need to blindly pick up the control channel on CORESET 2.
Activating a second set of control resources and/or a second search space configured in the first BWP corresponding to the second BWP may be activating the second set of control resources and the second search space together; or only activating a certain specific control resource set, but the search control corresponding to the control resource set is activated by default; or activating a certain search space, wherein the control resource set corresponding to the search space is already activated.
Based on the foregoing scheme, how to perform the activation and deactivation process of the second BWP is specifically described below:
the communication unit 51 blindly detects the PDCCH through the first control resource set corresponding to the first BWP to detect an activation instruction for at least one second BWP.
The instruction may be a PDCCH blindly picked up on the corresponding first CORESET on the currently active first BWP.
And the PDCCH is scrambled through the first RNTI. It should be noted that, the first RNTI indicates an RNTI different from various RNTIs defined 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 activation instruction is different from an instruction carried by the PDCCH scrambled by another RNTI. Further, in this embodiment, the first RNTI is used for user data scheduling, and is different from a cell-radio network temporary identity (C-RNTI), a radio network temporary identity (CS-RNTI) configured for scheduling; in addition, the first RNTI is used to distinguish a Modulation and Coding Scheme (MCS) table.
When the at least one second BWP is activated, a timer corresponding to the at least one second BWP is started or restarted. Accordingly, if the timer corresponding to the at least one second BWP is not expired, a first control resource set corresponding to the first BWP and a second control resource set corresponding to the at least one second BWP configured on the first BWP are detected.
It should be understood that each activated second BWP may correspond to a different timer, and certainly, multiple BWPs may also correspond to a timer, which is not described in detail in this embodiment.

Restarting or starting a timer corresponding to at least one second BWP when a data schedule for the at least one second BWP is detected at the second set of control resources. That is, if the second BWP data scheduling is monitored on the second core set corresponding to a certain activated 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 deactivates the second BWP and blindly detects the second control resource set corresponding to the second BWP configured on the first BWP when the timer corresponding to the second BWP expires. When the timer corresponding to BWP-2 times out, the UE deactivates 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 set of control resources and a second set of control resources are configured on a first BWP, and when an activation instruction for the second BWP is received on the first set of control resources, the first BWP is controlled to be activated, and a timer of the second BWP is started while the second BWP is activated; when the timer of the second BWP expires, stopping detecting the second control resource set corresponding to the second BWP configured on the first BWP, and as shown in the figure, the second control resource set does not perform detection any more after the timer of the second BWP expires.
Referring to fig. 4, one control resource set (such as the first control resource set in the figure) has a control resource set for the first BWP and a control resource set for the second BWP; when an activation instruction for a second BWP is received on a first set of control resources for a first BWP, controlling activation of the second BWP, starting a timer for the second BWP while the second BWP is activated; and when the timing of the second BWP is overtime, stopping detecting the control resource set corresponding to the second BWP configured on the first BWP.
It can be seen that, by adopting the above scheme, when a set of control resources for at least one second BWP is configured on one BWP and an activation instruction for the at least one second BWP is detected on the search space, the at least one second BWP is controlled to be activated; in this way, a BWP scenario is achieved that supports multiple activations at the same time.
