[0079]
Example 1
[0080]
At present, the start or restart of BWP-related timers can be triggered through downlink control signaling. For example, when a PDCCH used for scheduling or for indicating BWP handover is received on an active BWP, BWP-related timers are started or restarted. The inventor found that cell activation or addition will cause BWP activation. In this case, the network side does not need to send additional display signaling (such as PDCCH) to activate BWP. Therefore, it cannot trigger the start or restart of BWP related timers, which will cause the terminal device to fail. Perform BWP related operations within a reasonable time. Embodiment 1 of the present invention provides a partial bandwidth timing method, which can be solved by starting or restarting the timer related to BWP when an event related to cell addition or cell activation occurs. To solve the problem that BWP related timers cannot be started or restarted in the scenario of cell addition or activation.
[0081]
Figure 2 is a flowchart of this part of the bandwidth timing method in this embodiment, which is applied to the terminal device side. As shown in Figure 2, the method includes:
[0082]
Step 201: When an event related to cell addition or cell activation occurs, the terminal device starts or restarts a timer related to the BWP.
[0083]
In this embodiment, the network side manages the status of each cell according to the service volume of the terminal equipment and/or the channel quality of each cell. For example, when the service volume of the terminal equipment is large, or the channel quality of a certain cell is relatively high. Hershey, the network side will add a cell or activate a cell for the terminal device. In addition, it will also configure the BWP and the timer related to the BWP for the terminal device. In this embodiment, the terminal device is related to cell addition or cell activation. When the event occurs, start or restart the timer associated with the BWP (timer associate with the BWP).
[0084]
In this embodiment, the BWP may include: initial BWP (initial BWP), default BWP (default BWP), active BWP (active BWP), etc. The BWP may be a downlink BWP used by the terminal device to receive data sent by the network side It may be an uplink BWP where the terminal device sends data to the network side, where the frequency range corresponding to the uplink BWP and the downlink BWP may be the same or different, and this embodiment is not limited thereto.
[0085]
In one embodiment, the events related to cell addition or cell activation include: cell addition or cell activation causes the BWP to be activated.
[0086]
In this embodiment, when a cell is added or activated, the network side does not need to send additional control signaling to activate the BWP configured for the terminal device on the network side. The BWP configured for the terminal device on the network side will be added or activated as the cell is added or activated. When activated, the activated BWP is the first activated BWP. Therefore, when the currently activated BWP is activated due to cell addition or cell activation, starting or restarting the timer related to the activated BWP can also save credit.令Overhead.
[0087]
In an embodiment, the occurrence of an event related to cell addition or cell activation includes: receiving a signaling for adding a cell or activating a cell sent by the network side.
[0088]
In this embodiment, when the network side determines to add a cell or activate a cell for the terminal device, it will send signaling to indicate cell addition or cell activation, and the terminal device will successfully receive the cell addition or activation cell sent by the network side. When signaling, start or restart the timer related to BWP, which can also save signaling overhead.
[0089]
The signaling may be media access control layer (MAC) signaling, such as MAC control element (CE), or radio resource control signaling, which is not limited in this embodiment, for example, the signaling It can be a bitmap. When the bit value is 1 or 0, it indicates cell addition or cell activation, but this embodiment is not limited by this.
[0090]
In this embodiment, the above cell addition includes special cell (Spcell) addition, primary cell (PCell) addition or secondary cell (SCell) addition, and cell activation includes secondary cell (SCell) activation or serving cell (serving cell) activation. For example, when a terminal device is connected to the primary base station, the network device needs to configure and add a new primary cell to the secondary base station for the terminal device, that is, the primary cell is added; or the terminal device is connected to the base station, and based on the primary cell service, The network device configures and adds a new subordinate cell for the terminal device, that is, adding a subordinate cell. The above is only an example for description, and this embodiment is not limited by this.
[0091]
In this embodiment, in step 201, before starting or restarting the timer related to the BWP, the method may further include: activating the BWP.
[0092]
In this embodiment, the timer related to the BWP is used to control the terminal device to perform operations related to the BWP after the timer expires. Therefore, after the timer expires, the method may further include (not shown) ): The terminal device performs operations related to the BWP, and the related operations include: activating the BWP or deactivating the BWP, resuming use of the BWP or suspending the BWP, changing the parameter configuration of the BWP, and switching the BWP.
[0093]
For example, the BWP-related timer is a BWP-Inactivity Timer (BWP-InactivityTimer). After the BWP-inactivity timer expires, the terminal device switches from the current BWP to the default BWP or the initial BWP, where it is the terminal device on the network side When the default BWP is configured, the terminal device switches to the default BWP, and when the default BWP is not configured, the terminal device switches to the initial BWP, where the current BWP is the activated BWP, and the activated BWP is not the initial BWP, but this embodiment does not This is a limitation. Therefore, after the timer expires, the terminal device performs BWP switching, which may achieve the effect of energy saving.
[0094]

[0096]
Step 301: Receive signaling sent by the network side, where the signaling is used to indicate to add a cell;
[0097]
For example, the signaling may be RRC signaling.
[0098]
Wherein, the signaling may also include related parameters of the cell to be added or activated, and related information of the BWP configured on the network side, but this embodiment is not limited by this. The related parameters and the related information are also It can be sent separately or together through at least one other signaling. For the specific implementation of the related parameters and related information, please refer to Embodiment 4, which will not be repeated here.
[0099]
Step 302: Add a cell to trigger activation of the configured BWP;
[0100]
Step 303, while activating the configured BWP, start or restart a timer related to the BWP;
[0101]

[0105]
Wherein, the signaling may also include related parameters of the cell to be activated, and related information of the BWP configured on the network side, but this embodiment is not limited by this. The related parameters and the related information can also be passed through other related parameters. At least one signaling is sent separately or together.
[0106]
Step 402: Activate the cell and activate the configured BWP;
[0107]
Step 403, while activating the configured BWP, start or restart a timer related to the BWP;
[0108]
Step 404: After the timer related to the BWP expires, the terminal device switches from the currently active BWP to the default BWP.
[0109]
It can be known from the above embodiments that by starting or restarting the timer related to BWP when an event related to cell addition or cell activation occurs, the problem that the timer related to BWP cannot be started or restarted under the scenario of cell addition or activation can be solved. , Saving signaling.
[0110]
Example 2
[0111]
Currently, downlink control signaling can be used to trigger the start or restart of BWP-related timers. For example, when a PDCCH used for scheduling or for instructing BWP switching is received on an active BWP, BWP-related timers are started or restarted. In addition, the inventor found that the random access response (random access response) in the random access process is also scheduled by the PDCCH. If only the PDCCH used for scheduling is received as a trigger to start or restart the BWP-related timer Condition, then when the downlink scheduling of RAR is received, the timer related to starting or restarting BWP will also be triggered. However, in order to prevent the terminal from being set on a different BWP for random access, it is currently not allowed for terminal equipment to run BWP-related timers during random access or perform BWP handover during random access, that is, at the terminal When the device initiates (initializes) the random access process, it should stop the timer related to the BWP. Therefore, not all scenarios where the PDCCH used for scheduling is received need to trigger the start or restart of the BWP related timer.
[0112]
In order to solve the above problems, Embodiment 2 of the present invention provides a partial bandwidth timing method that will start or restart when control signaling indicating scheduling is received and the control signaling indicating scheduling is not related to the random access process The timer related to BWP can distinguish the common control signaling used for scheduling from the control signaling used for RAR scheduling. After receiving the common control signaling used for scheduling (not related to the random access process) When receiving control signaling for RAR scheduling or other control signaling related to the random access process, do not start or restart the timer related to BWP to ensure The terminal device does not perform BWP handover during the random access process.
[0113]
FIG. 5 is a flowchart of a partial bandwidth timing method in this embodiment, which is applied to the terminal device side. As shown in FIG. 5, the method includes:
[0114]
In step 501, the terminal device starts or restarts a timer related to BWP when it receives control signaling indicating scheduling and the control signaling indicating scheduling is not related to the random access procedure (Random Access procedure).
[0115]
In this embodiment, when the control signaling for indicating scheduling is received, and the control signaling for indicating scheduling is not related to the random access process (that is, starting or restarting the timer related to the BWP will not cause the random access When the BWP switch occurs during the incoming process), start or restart the timer related to the BWP, that is, when the control signaling used to indicate the scheduling is received, and the control signaling indicating the scheduling is related to the random process, the or Restart the timer related to the BWP to ensure that the terminal device does not switch the BWP during the random access process.
[0116]
In this embodiment, the control signaling used to indicate scheduling may be a Physical Downlink Control Channel (PDCCH), where the control signaling may be received on the BWP, for example, the BWP may be activated BWP, that is, the PDCCH indicating scheduling can be received on the activated BWP, the above is only an exemplary description, and this embodiment is not intended to be a limitation.
[0117]
In this embodiment, the control signaling indicating scheduling is independent of the random access process means that the control signaling is defined by a radio network temporary identifier (RNTI) other than the random access radio network temporary identifier (RA-RNTI) ) Scrambling, or the control signaling does not indicate the scheduling random access response (RAR), or the control signaling is not received during the random access process, or the random access process is not currently in progress, or the terminal device The random access procedure has been completed, or the terminal device has successfully received the random access response (RAR) in the random access procedure.
[0118]
Wherein, the random access process may be a contention-based random access process or a non-contention-based random access process.
[0119]
For example, during the random access process, the UE may receive a random access response message (Msg.2) returned by the network side by monitoring the PDCCH, where the PDCCH is scrambled by the RA-RNTI, and the UE according to the RA-RNTI When descrambling the PDCCH successfully, it can receive the Msg.2 returned by the network side. The Msg.2 includes RAR. Therefore, when the RA-RNTI is used to scramble the control signaling, it means that the control signaling is used for Carrying Msg.2, that is, the control signaling is related to the random access process, that is, when the control signaling is scrambled by RNTI other than RA-RNTI, it means that the control signaling has nothing to do with the random access process. At this time, triggering to start or restart the timer related to BWP will not cause BWP switching during the random access process.
[0120]
For example, the control signaling is not received during the random access process, or the random access process is not currently in progress, it can indicate that the control signaling is not related to the random access process, at this time triggering start or restart and BWP Related timers will not cause BWP switching during random access.
[0121]
For example, when the terminal device has completed the random access process, where the completion of the random access process includes the failure or success of the random access process, it may indicate that the control signaling has nothing to do with the random access process, and the start or restart is triggered at this time. BWP-related timers will not cause BWP handover during random access. Among them, when the random access process is based on a non-competition random access process, the success of the random access process refers to the successful reception of Msg.2, and the failure of the random access process refers to the failure of the Msg.2 reception for a predetermined number of times; When the access process is a random access process based on contention, the success of the random access process refers to the successful reception of Msg.4, and the failure of the random access process refers to the predetermined number of Msg.4 reception failures.
[0122]
For example, when the random access process is based on a non-contention random access process, the control signaling does not indicate a scheduled random access response (RAR), which means that the control signaling is not received during the random access process In this case, when the terminal device receives the control signaling used to indicate the scheduling, it is a common control signaling used for scheduling, and has nothing to do with the random access process. That is, the start or restart is triggered at this time and the BWP The related timer will not cause BWP handover during the random access process.
[0123]
For example, when the random access process is a contention-based random access process, the control signaling does not indicate the scheduling random access response (RAR), that is, it can indicate that the control signaling can be received in Msg.4. The control signaling for contention resolution may also be ordinary control signaling used to indicate scheduling received outside the contention of the random access process, and has nothing to do with the random access process, that is, the start or restart is triggered at this time. BWP related timers will not cause BWP switching during random access.
[0124]

[0125]
For example, when the random access process is a contention-based random access process, the terminal device has successfully received the random access response (RAR) in the random access process, which can indicate that the terminal device has completed the reception of Msg.2 In this case, the control signaling used by the terminal device to indicate scheduling may be the control signaling received in Msg. 4 for contention resolution, or it may be outside the contention of the random access process. The received control signaling used to indicate scheduling, because the RAR in the random access process has been successfully received, that is, the signaling has nothing to do with the random access process, that is, triggering the start or restart of the timer related to the BWP at this time is not It will cause BWP handover during random access.

[0128]
It can be known from the above embodiment that when receiving ordinary control signaling for scheduling (not related to the random access process), start or restart the timer related to BWP, and after receiving control signaling or RAR scheduling In other control signaling related to the random access process, the timer related to the BWP is not started or restarted, so as to ensure that the terminal device does not switch the BWP during the random access process.

If it needs to start or restart the timer , Additional downlink control signaling is needed to trigger the start or restart of the BWP-related timer.
[0131]
