Description

Method for activating and configuring bandwidth part and terminal equipment

Technical field

The present invention relates to the technical field of information processing, and in particular, to a method for activating 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.

Background technique

New Radio (NR, New Radio) supports a system bandwidth that is much larger than the LTE (Long Terminal Evolution, Long Term Evolution) maximum system bandwidth of 20 MHz. For some terminals, due to limited capabilities, it may not be able to support the full system bandwidth; To improve scheduling efficiency and from the perspective of terminal power saving, NR introduces 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 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.

However, the timer-based BWP switching mechanism does not support scenarios where multiple BWPs are activated simultaneously, so a new timer mechanism needs to be designed to support multiple simultaneously activated BWPs.

Step 201: Detect an activation instruction for at least one second BWP in a first control resource set and a first search space configured on a first bandwidth part BWP; wherein the first BWP is in an activated state and the at least one The second BWP is in a deactivated state;

Step 202: When an activation instruction for at least one second BWP is detected, activate the at least one second BWP.

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. In addition, the first BWP here may not be a BWP configured in a connected state of the terminal; the foregoing second BWP may be configured in a connected state.

That is, the network configures at least two BWPs for the connected terminal devices. The initial BWP can also be considered as a configured BWP. For example, a BWP is configured on the connected network, and the initial BWP is retained while the other BWPs configured are activated. .

Further, this embodiment further includes:

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

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 the first BWP is further 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, 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 control resource set.

That is, 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 to the same BWP;

Different control resource sets can also correspond to different BWPs. For example, a first control resource set and a second control resource set can be configured on the first BWP. A first control resource set can correspond to a first BWP and a second control resource set corresponds to a second BWP. BWP.

In addition, one BWP may activate multiple BWPs, where one BWP may be the aforementioned first BWP, and multiple BWPs may be multiple second BWPs activated by the first BWP.

It should be understood that multiple second BWPs are only used to describe 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, among the activation instructions for at least one second BWP, the activation instructions may be activation instructions for one BWP or activation instructions for multiple BWPs. In this embodiment, the activation instructions will be activated by the activation instructions. One or more of the BWPs are referred to as the second BWP.

Of course, in the second BWP in this embodiment, a second control resource set and / or a second search space may also be configured, but details are not described again.

The method further includes: when the at least one second BWP is in an activated state, being able to send and / or receive data on the at least one second BWP, and simultaneously detecting on the first BWP corresponding to at least one first BWP A second control resource set and / or a second search space of the two BWPs.

It should be noted that when the second BWP is activated, data is not necessarily sent and received. When the second BWP is activated and the schedule is received, data will be transmitted on the second BWP. Receive or send.

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

The activation of the second BWP further includes: activating a related channel or signal corresponding to the at least one second BWP. The activation of the second BWP may also include activation of related channels / signals that have an association relationship with it; when the second BWP is activated, all or part of the search space corresponding to CORESET2 that has an association relationship with it is activated.

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, it may be CRS, DMRS, and the like.

When the second BWP is activated, the method further includes: activating 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 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 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 a "deactivated" state, that is, the UE does not need to blindly pick up the control channel on CORESET2.

Activating the second control resource set and / or the second search space corresponding to the second BWP configured in the first BWP may be activating the second control resource set and the second search space together; or, activating only A certain control resource set, but the search control corresponding to the control resource set is activated by default; or a certain search space is activated, and the control resource set corresponding to the search space is already activated.

Based on the foregoing scheme, the following specifically describes how to perform the activation and deactivation processing of the second BWP:

The detecting an activation instruction for at least one second BWP includes:

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

The terminal device receives an instruction to activate the second BWP. The instruction may be a PDCCH blindly picked on the first CORESET that has a corresponding relationship on the currently activated first BWP.

The PDCCH is scrambled by using a first RNTI. It should be noted that the first RNTI refers to an RNTI that is different from various RNTIs defined in the prior art, that is, the first RNTI is used to scramble the PDCCH, so that the receiver, that is, the terminal device To determine that the currently received activation instruction is different from the instruction 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 the C-RNTI and CS-RNTI; in addition, the MCS table can be distinguished by using the first RNTI.

When at least one second BWP is activated, a timer corresponding to the at least one second BWP is started or restarted. Correspondingly, if the timer corresponding to at least one second BWP has not timed out, the first control resource set configured on the first BWP and corresponding to the first BWP and the first control resource set corresponding to the at least one second BWP are detected. The second control resource collection.

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

The detection is configured on the first BWP, the first control resource set corresponding to the first BWP, and a different search space corresponding to the first control resource set; and the 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 corresponding relationship, and a different search space corresponding to the second control resource set.

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

When data scheduling 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 an activated second BWP (in accordance with the corresponding search space period), a timer corresponding to the second BWP is started / restarted.

When the timer corresponding to the second BWP expires, the second BWP is deactivated 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 deactivates BWP-2 and no longer blindly picks up the second CORESET corresponding to BWP-2 and configured on BWP-1.

Referring to FIG. 3, a first control resource set and a second control resource set are configured on the first BWP. When an activation instruction for the second BWP is received on the first control resource set, control activates the second BWP and activates the second The 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 set After the timer of the second BWP expires, no further detection is 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 set receives an activation instruction for the second BWP, it controls the activation of the second BWP, and activates the timer of the second BWP while activating the second BWP. When the timer of the second BWP expires, it stops detecting the configured on the first BWP. The control resource set corresponding to the second BWP.

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

The activation of the second BWP may also include activation of related channels / signals that have an association relationship with it; when the second BWP is activated, all or part of the search space corresponding to CORESET2 that has an association relationship with it is activated.

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 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 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 a "deactivated" state, that is, the UE does not need to blindly pick up the control channel on CORESET2.

The communication unit 51 blindly detects a PDCCH through a 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 blindly picked PDCCH on a first CORESET with a corresponding relationship on a currently activated first BWP.

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