A wireless communication method and device

technical field

The present application relates to the communication field, and in particular to a wireless communication method and device.

Background technique

In the long term evolution (LTE) communication system, the discontinuous reception (DRX) function is defined. When the terminal device is in the radio resource control (radio resource control, RRC) connected (connected) state, DRX can control The terminal device monitors the behavior of a physical downlink control channel (PDCCH), saving unnecessary power consumption of the terminal device.

In the carrier aggregation (carrier aggregation, CA) scenario, the terminal device can aggregate the carrier units corresponding to multiple server cells such as the primary cell (PCell) and the secondary cell (secondary cell, SCell) to send data, so that Improve transmission bandwidth. At present, the DRX function is aimed at the media access control (media access control, MAC) entity of the terminal device, that is, one MAC entity is configured with one DRX function, so the terminal device monitors the PDCCH on the PCell and SCell according to the same DRX parameters, that is, when When the terminal equipment monitors the PDCCH on the PCell, it also monitors the PDCCH on the SCell at the same time.

However, in actual scheduling, the scheduling characteristics on PCell and SCell are usually different. For example, there are more and more frequent scheduling on the PCell, and less and more sparse scheduling on the SCell. If the time to monitor the PDCCH on the PCell and the SCell is the same, when the terminal device monitors the PDCCH on the SCell, it will rarely receive the PDCCH, thus causing waste of power consumption of the terminal device.

Detailed ways

In order to make the description of the following embodiments clear and concise, a brief introduction of related concepts or technologies is given first:

New radio access technical (New RAT or NR) follows the DRX mechanism of LTE. Among them, New RAT or NR can also be called the fifth generation (the fifth generation, 5G) mobile communication system. A terminal device (for example, a user equipment (user equipment, UE)) may be configured with a DRX function in an RRC connected state. DRX can control UE to monitor (monitor) PDCCH in certain time periods in a DRX cycle (DRX cycle), and not monitor PDCCH in other time periods. Exemplarily, DRX can control UE to monitor C-RNTI, configure scheduling RNTI (configured scheduling RNTI, CS-RNTI), intermittent radio network temporary identifier (interruption RNTI, INT-RNTI), and time slot format to indicate wireless network temporary Slot format indication RNTI, SFI-RNTI, semi-persistent CSI RNTI, SP-CSI-RNTI, transmit power control RNTI, TPC- PUCCH-RNTI), transmit power control physical uplink shared channel wireless network temporary identification (transmit power control physical uplink shared channel RNTI, TPC-PUSCH-RNTI) or transmission power control sounding reference signal wireless network temporary identification (transmit power control sounding reference signal RNTI , TPC-SRS-RNTI) scrambled PDCCH. Wherein, RNTI is an abbreviation of radio network temporary identity (radio network temporary identity). Since the PDCCH can be used to bear DCI, RNTI scrambling the PDCCH can also be understood as RNTI scrambling DCI. Wherein, the process of scrambling the DCI may be after the DCI is attached with a cyclic redundancy check (cyclic redundancy check, CRC), and the wireless network temporary identifier is used to scramble the CRC check bit; or after the RNTI is used to attach the CRC to the DCI sequence scrambling.

As shown in Figure 1, a DRX cycle includes On Duration and Opportunity for DRX. Among them, OnDuration can be called the on-duration, and Opportunity for DRX can be called the DRX opportunity. At the start moment of On Duration (or the start moment of DRX Cycle), the DRX on-duration timer (drx-onDurationTimer, also called onDurationTimer) can be started. The duration of drx-onDurationTimer is the duration of OnDuration, that is, the duration of drx-onDurationTimer includes a duration for the start of a DRX cycle. UE can monitor PDCCH during On Duration, that is, UE can monitor PDCCH during drx-onDurationTimer operation. When the UE receives a PDCCH that schedules a new transmission of uplink (uplink, UL) or downlink (downlink, DL) during the operation of drx-onDurationTimer (that is, a newly transmitted PDCCH is received), it can start (or restart) Inactive Timer (drx-InactivityTimer). The duration of drx-InactivityTimer includes a period of time after the UE receives a PDCCH, for example, it may be a period of time after the subframe where the PDCCH is located, or a period of time after the PDCCH opportunity where the PDCCH is located. Wherein, the PDCCH can be used to indicate a new UL or DL transmission to the UE. The PDCCH opportunity is a period of time (for example, one or more symbols) for the terminal equipment to monitor the PDCCH, and may also be referred to as a PDCCH monitoring opportunity. The UE may continue to monitor the PDCCH during the running of the drx-InactivityTimer until the drx-InactivityTimer times out.

In addition, when the UE monitors the PDCCH of the hybrid automatic repeat request (HARQ) of data, since there is no fixed timing relationship between the previous transmission and the retransmission, the uplink and downlink HARQ processes (process ), respectively define a time window, allowing the UE to start monitoring the uplink or downlink PDCCH after counting from the previous uplink or downlink transmission and continuing the time window. The time window can be realized by a timer. Each uplink HARQ process and each downlink HARQ process may correspond to a timer. For example, the timer corresponding to the downlink HARQ process is HARQ RTT Timer or drx-HARQ-RTT-TimerDL, and the timer corresponding to the uplink HARQ process is ULHARQ RTT Timer or drx-HARQ-RTT-TimerUL. Among them, RTT is the abbreviation of Round Trip Time. For the uplink HARQ process, when the corresponding timer times out, the corresponding uplink retransmission timer (drx-RetransmissionTimerUL, also called drx-ULRetransmissionTimer) is started. For the downlink HARQ process, when the corresponding timer times out, the corresponding downlink retransmission timer (drx-RetransmissionTimerDL, also called drx-RetransmissionTimer) is started. When drx-RetransmissionTimerUL or drx-RetransmissionTimerDL is running, the UE can monitor the PDCCH. Among them, drx-RetransmissionTimerUL can be defined as: the maximum duration until a grant for UL retransmission is received (the maximum duration of receiving an uplink retransmission grant). drx-RetransmissionTimerDL can be defined as: the maximum duration until a grant for DL retransmission is received (the maximum duration of receiving a downlink retransmission).

When the DRX cycle is configured, the UE can monitor the PDCCH during the Active time; otherwise, the UE does not need to monitor the PDCCH. Among them, the activation period includes:

1) The time period when at least one of the following timers is running: drx-onDurationTimer, drx-InactivityTimer, drx-RetransmissionTimerUL, drx-RetransmissionTimerDL or contention resolution timer (ra-ContentionResolutionTimer or mac-ContentionResolutionTimer). Wherein, the contention resolution timer may be used to determine the time length for the terminal device to monitor the PDCCH indicating message 4 after sending message 3 in the random access process.

2) A Scheduling Request (SR) is sent and is pending. When an SR is triggered, the SR is pending until it is cancelled. The time period during which the SR is suspended is the time period between the time when the SR is sent and the time when the SR is canceled.

3) After successfully receiving a RAR, the terminal device has not yet received a PDCCH indicating a new transmission. Wherein, the PDCCH is scrambled by the C-RNTI, and the RAR is not the RAR of the random access preamble selected by the UE from the contention-based random access preamble.

Embodiments of the present application provide a wireless communication method and apparatus, which are applied to a process in which a terminal device monitors a PDCCH or does not monitor a PDCCH in a DRX cycle. For example, in a carrier aggregation scenario, a terminal device detects a PDCCH or does not monitor a PDCCH on a PCell, and a process detects a PDCCH or does not monitor a PDCCH on one or more SCells.

An embodiment of the present application provides a wireless communication method, as shown in FIG. 3 , including:

300. The network device sends first information, where the first information is used to configure the SCell of the terminal device.

For example, the network device may send an RRC message to the terminal device, where the RRC message includes the first information.

Optionally, the network device may also activate one or more of the configured SCells of the terminal device. Network devices can also deactivate activated SCells.

301. The terminal device receives first information, where the first information is used to configure an SCell of the terminal device.

The terminal device may receive the RRC message sent by the network device, where the RRC message includes the first information. The first information is used to configure the SCell of the terminal device. The configured SCells of the terminal device may include one or more SCells, for example, the terminal device may include 1, 2 or 3 SCells.

Optionally, the RRC message can also be used to reconfigure, add and remove SCells for the terminal equipment.

302. If the first condition is met, the terminal device performs the first processing and the second processing.

Wherein, the first condition includes that the first timer is in a running state. The first timer is used to determine the time length for the terminal equipment to monitor the PDCCH within one DRX cycle. For example, the first timer may be drx-onDurationTimer.

The first processing may include at least one of the following: monitoring the PDCCH on the PCell; monitoring the PDCCH of the PCell. That is, the first process may include monitoring the PDCCH on the PCell. Alternatively, the first process may include monitoring the PDCCH of the PCell. Alternatively, the first process may include monitoring the PDCCH on the PCell and monitoring the PDCCH of the PCell.

The second processing includes at least one of the following: not monitoring the PDCCH on the SCell; not monitoring the PDCCH of the SCell. That is, the second processing may include not monitoring the PDCCH on the SCell. Alternatively, the second processing may include not monitoring the PDCCH of the SCell. Alternatively, the second processing may include not monitoring the PDCCH on the SCell and not monitoring the PDCCH of the SCell. The aforementioned SCell may include a configured or activated SCell of the terminal device.

In this embodiment of the present application, monitoring the PDCCH on a serving cell (for example, PCell or SCell) may include at least one of the following: monitoring the PDCCH of the serving cell on a serving cell, and monitoring other (one or multiple) PDCCH of the serving cell. Monitoring the PDCCH of a serving cell may include at least one of the following: monitoring the PDCCH of the serving cell on the serving cell, and monitoring the PDCCH of the serving cell on other (one or more) serving cells.

Wherein, the PDCCH of a serving cell means that the transmission indicated by the PDCCH is the transmission on the serving cell. For example, the PDCCH of the PCell means that the transmission indicated by the PDCCH is the transmission on the PCell. The PDCCH of the SCell means that the transmission indicated by the PDCCH is the transmission on the SCell. For example, the PDCCH of SCell1 means that the transmission indicated by the PDCCH is the transmission on SCell1.

For example, as shown in Fig. 3a, it is assumed that a terminal device is configured or activated with one SCell. Before the first timer runs, the terminal device may not monitor the PDCCH on the PCell and the SCell. After the first timer starts running, the terminal device performs the first processing, such as monitoring the PDCCH on the PCell, and performs the second processing, such as not monitoring the PDCCH on the SCell.

In a possible design, the first condition also includes one or more of the following situations:

1) The second timer is not running. Optionally, it may be that the second timer corresponding to one SCell is not in the running state. Or, it may be that the same second timer corresponding to multiple SCells is not in the running state. Wherein, the second timer is used to determine the time length for the terminal device to monitor the PDCCH after receiving the PDCCH, or the second timer is used to determine the time length for the terminal device to monitor the PDCCH after receiving the PDCCH indicating a new transmission. For example, the second timer can be Drx-InactivityTimer.

For example, if the second timer corresponding to an SCell is not in the running state, when the first timer is in the running state, the terminal device may monitor the PDCCH on the PCell and not monitor the PDCCH on the SCell. If the same second timer corresponding to multiple SCells is not in the running state, when the first timer is in the running state, the terminal device may monitor the PDCCH on the PCell, but not monitor the PDCCH on the multiple SCells. For another example, if the second timer corresponding to an SCell is not in the running state, when the first timer is in the running state, the terminal device may monitor the PDCCH of the PCell and not monitor the PDCCH of the SCell. If the same second timer corresponding to multiple SCells is not in the running state, when the first timer is in the running state, the terminal device may monitor the PDCCH of the PCell, but not monitor the PDCCH of the multiple SCells.

In addition, if the second timer is in the running state, regardless of whether the first timer is in the running state, the terminal device monitors the PDCCH on the SCell until the second timer expires; or, the terminal device monitors the PDCCH of the SCell until the second timer expires; Or the terminal device monitors the PDCCH on the SCell and monitors the PDCCH of the SCell until the second timer expires.

For example, as shown in Figure 3b, it is assumed that the UE is configured or activated with one SCell. Before the first timer (for example, drx-onDurationTimer) runs, the UE does not monitor the PDCCH on the PCell and the SCell. When the drx-onDurationTimer starts running, the UE starts to monitor the PDCCH on the PCell, but does not monitor the PDCCH on the SCell. After the second timer (for example, drx-InactivityTimer) starts to run, the UE starts to monitor the PDCCH on the SCell. UE can monitor PDCCH on SCell until drx-InactivityTimer expires. Optionally, the UE can monitor the PDCCH on the PCell until the drx-InactivityTimer times out.

In a possible design, if the terminal device monitors the PDCCH on the PCell or the SCell, or if the terminal device monitors the PDCCH indicating a new transmission on the PCell or the SCell, the terminal device may start or restart the second timer. Optionally, if the terminal device detects the PDCCH on the PCell or an SCell, the terminal device may start or restart the second timer corresponding to the SCell. If the terminal device detects the PDCCH on the PCell or any one of the multiple SCells, the terminal device may start or restart the same second timer corresponding to the multiple SCells.

For example, as shown in FIG. 3c, during the running of the first timer, if the terminal device detects the PDCCH on the PCell, the second timer may be started. During the running of the second timer, if the terminal device detects the PDCCH on the SCell, the second timer may be restarted.

2) The downlink retransmission timer is not running. For example, the downlink retransmission timer may be drx-RetransmissionTimerDL. Optionally, the downlink retransmission timer may be a downlink retransmission timer corresponding to a DL HARQ process on the SCell.

In addition, if the downlink retransmission timer is running, regardless of whether the first timer is running, the terminal device can monitor the PDCCH on the SCell; or monitor the PDCCH of the SCell; or monitor the PDCCH on the SCell and monitor the PDCCH of the SCell. Optionally, if the downlink retransmission timer is running, the terminal device may monitor the PDCCH on the PCell; or monitor the PDCCH of the PCell; or monitor the PDCCH on the PCell and monitor the PDCCH of the PCell.

3) The uplink retransmission timer is not running. For example, the uplink retransmission timer may be drx-RetransmissionTimerUL. Optionally, the uplink retransmission timer may be the uplink retransmission timer corresponding to the UL HARQ process on the SCell.

In addition, if the uplink retransmission timer is running, regardless of whether the first timer is running, the terminal device can monitor the PDCCH on the SCell; or monitor the PDCCH of the SCell; or monitor the PDCCH on the SCell and monitor the PDCCH of the SCell. Optionally, if the uplink retransmission timer is running, the terminal device may monitor the PDCCH on the PCell; or monitor the PDCCH of the PCell; or monitor the PDCCH on the PCell and monitor the PDCCH of the PCell.

4) The contention resolution timer is not running. Optionally, the contention resolution timer may be a contention resolution timer corresponding to the SCell.

In addition, if the contention resolution timer is running, regardless of whether the first timer is running, the terminal device can monitor the PDCCH on the SCell; or monitor the PDCCH of the SCell; or monitor the PDCCH on the SCell and monitor the PDCCH of the SCell. Optionally, if the contention resolution timer is running, the terminal device may monitor the PDCCH on the PCell; or monitor the PDCCH of the PCell; or monitor the PDCCH on the PCell and monitor the PDCCH of the PCell.

5) The scheduling request (scheduling request, SR) sent by the terminal device is not in a pending state. Optionally, the scheduling request may be a scheduling request sent on the SCell.

In addition, if the SR sent by the terminal device is in a pending state, regardless of whether the first timer is running, the terminal device can monitor the PDCCH on the SCell; or monitor the PDCCH of the SCell; or monitor the PDCCH on the SCell and monitor the PDCCH of the SCell . Optionally, if the SR sent by the terminal device is in a pending state, the terminal device may monitor the PDCCH on the PCell; or monitor the PDCCH of the PCell; or monitor the PDCCH on the PCell and monitor the PDCCH of the PCell.

6) The terminal device is not in the state of not receiving a PDCCH indicating a new transmission after successfully receiving a Random Access Response (Random Access Response, RAR). Wherein, it indicates that the newly transmitted PDCCH is scrambled by C-RNTI, RAR is a response to the target random access preamble, and the target random access preamble does not belong to the contention-based random access preamble. Optionally, the random access response may be a random access response received on the SCell.

In addition, if the terminal device does not receive the PDCCH indicating the new transmission after successfully receiving the RAR, regardless of whether the first timer is running, the terminal device can monitor the PDCCH on the SCell; or monitor the PDCCH of the SCell; or monitor the PDCCH on the SCell PDCCH and monitor the PDCCH of the SCell. Optionally, if the terminal device does not receive the PDCCH indicating a new transmission after successfully receiving the RAR, the terminal device may monitor the PDCCH on the PCell; or monitor the PDCCH of the PCell; or monitor the PDCCH on the PCell and monitor the PDCCH of the PCell.

Exemplarily, in a possible situation, if the first timer is in the running state and the second timer is not in the running state, the terminal device performs the first processing and the second processing. In yet another possible situation, if the first timer is in the running state, and the second timer and the downlink retransmission timer are not in the running state, the terminal device performs the first processing and the second processing. In yet another possible situation, if the first timer is running and the second timer, the downlink retransmission timer and the uplink retransmission timer are not running, the terminal device performs the first processing and the second processing .

Optionally, while the terminal device is performing the second processing, one or more of the following operations may be performed: the terminal device does not transmit a channel sounding reference signal (Sounding Reference Signal, SRS) on the SCell, and the terminal device does not report the channel on the SCell Status information (Channel State Information, CSI), the terminal device does not transmit the physical uplink control channel (Physical Uplink Control Channel, PUCCH) on the SCell, the terminal device sets the SCell to the dormant state and the terminal device sets the SCell to the deactivated state.

In the prior art, the terminal equipment monitors the PDCCH on the PCell and the SCell according to the same DRX parameter. Since the terminal device rarely receives the PDCCH while monitoring the PDCCH on the SCell, power consumption of the terminal device is wasted. Based on the solution provided by the embodiment of the present application, when the first timer is running, the terminal device may not monitor the PDCCH on the SCell and/or not monitor the PDCCH of the SCell, thereby reducing the power consumption of the terminal device monitoring the PDCCH.

Another embodiment of the present application provides a wireless communication method, as shown in FIG. 4 , including:

400. The network device sends first information, where the first information is used to configure the SCell of the terminal device.

For example, the network device may send an RRC message to the terminal device, where the RRC message includes the first information.

401. The terminal device receives first information, where the first information is used to configure an SCell of the terminal device.

For the first information, reference may be made to the related description of step 301, which will not be repeated here.

In a possible design, after receiving the first information, the terminal device may choose to execute any one of steps 402 to 405, so as to start or restart the third timer. Wherein, the third timer is used to determine the time length of the third processing. The terminal device performs the third processing during the running of the third timer, and for the third processing, refer to the related description of step 406 below.

402. If the second condition is met, the terminal device starts or restarts a third timer.

Wherein, the second condition includes any one of the following: the terminal device monitors the PDCCH on the PCell; the terminal device monitors the PDCCH on the SCell; the terminal device monitors the PDCCH of the PCell; the terminal device monitors the PDCCH of the SCell. For example, if the terminal device detects the PDCCH on the PCell; or if the terminal device detects the PDCCH on the SCell; or if the terminal device detects the PDCCH of the PCell; or if the terminal device detects the PDCCH of the SCell, the terminal device starts or restarts the third timer.

For example, as shown in Fig. 4a, it is assumed that a terminal device is configured or activated with one SCell. When the third timer is not running, if the terminal device receives the PDCCH of the PCell, the third timer starts, and the terminal device performs the third process during the running of the third timer until the third timer times out. Afterwards, if the terminal device receives the PDCCH of the PCell again, the third timer is started. During the running of the third timer, if the terminal device receives the PDCCH of the SCell, restart the third timer. The terminal device performs the third process during the running of the third timer until the third timer times out.

In a possible design, in the case that the third timer is for all SCells configured to the terminal device, if the terminal device receives the PDCCH indicating new transmission from the PCell, or receives the PDCCH in all SCells configured to the terminal device The terminal device starts or restarts the third timer for any PDCCH indicating new transmission of the SCell.

In a possible design, when the third timer is for a certain SCell configured to the terminal device (that is, each SCell in all SCells configured to the terminal device corresponds to a third timer), if The terminal device receives a PDCCH indicating new transmission of the PCell or the SCell, and the terminal device starts or restarts the third timer corresponding to the SCell.

403. If the third condition is met, the terminal device starts or restarts a third timer.

Wherein, the third condition includes any one of the following: the terminal device monitors the PDCCH on the SCell; the terminal device monitors the PDCCH of the SCell. For example, if the terminal device detects the PDCCH on the SCell, the terminal device starts or restarts the third timer. Alternatively, if the terminal device detects the PDCCH of the SCell, the terminal device starts or restarts the third timer. Alternatively, if the terminal device detects the PDCCH on the SCell or the PDCCH of the SCell, the terminal device starts or restarts the third timer.

For example, as shown in Figure 4b, it is assumed that a terminal device is configured or activated with one SCell. When the third timer is not running, if the terminal device receives the PDCCH of the SCell, the third timer is started, and the terminal device performs the third process during the running period of the third timer. During the running of the third timer, if the terminal device receives the PDCCH of the SCell, the third timer is restarted. The terminal device performs the third process during the running of the third timer until the third timer times out.

In a possible design, when the third timer is for all SCells configured to the terminal device, if the terminal device receives a PDCCH indicating new transmission from any SCell, the terminal device starts or restarts the third timer device.

In a possible design, when the third timer is for a certain SCell configured for the terminal device, if the terminal device receives a PDCCH indicating new transmission of the SCell, the terminal device starts or restarts the SCell corresponding to the third timer.

Optionally, if the terminal device detects the PDCCH on the PCell, the terminal device may not operate the third timer, that is, not start or restart the third timer.

404. If the second timer is started or restarted, the terminal device starts or restarts a third timer.

The second timer is used to determine the time length for the terminal device to perform the fourth process after receiving the PDCCH. The fourth processing includes at least one of the following: monitoring the PDCCH on the PCell; monitoring the PDCCH of the PCell. That is, the fourth process may include monitoring the PDCCH on the PCell. Alternatively, the fourth process may include monitoring the PDCCH of the PCell. Alternatively, the fourth process may include monitoring the PDCCH on the PCell and monitoring the PDCCH of the PCell. For related processes, reference may be made to related descriptions in step 302, and details are not repeated here.

Exemplarily, the second timer may be drx-InactivityTimer. If drx-InactivityTimer is started or restarted, start or restart the third timer. For example, as shown in Fig. 4c, it is assumed that a terminal device is configured or activated with one SCell. If the drx-InactivityTimer starts (for example, after the terminal device receives a PDCCH on the PCell, the drx-InactivityTimer starts to run), then the third timer starts. The terminal device performs the fourth processing until the second timer expires during the running of the second timer; the terminal device performs the third processing until the third timer expires during the running of the third timer. After the third timer expires, if the drx-InactivityTimer is restarted (for example, the terminal device restarts the drx-InactivityTimer after receiving a PDCCH on the PCell during the running of the drx-InactivityTimer), the third timer starts. During the running of the third timer, if the drx-InactivityTimer is restarted, the third timer is restarted. During the running of the third timer of the terminal device, the third processing is performed until the third timer times out.

Optionally, the length of the third timer is smaller than the length of the second timer. The length of the timer may also be referred to as the duration of the timer. Wherein, the length of the third timer may be configured by the network device, for example, may be configured by the network device through RRC signaling. In this way, since the length of the third timer is shorter than the length of the second timer, the duration for the terminal device to monitor the PDCCH on the SCell is shorter than the duration for the terminal device to monitor the PDCCH on the PCell, thereby reducing the function of the terminal device to monitor the PDCCH of the SCell. consumption.

In a possible design, when the third timer is for all SCells, if the second timer is started, the terminal device starts or restarts the third timer.

In a possible design, when the third timer is for a certain SCell (each SCell in all SCells configured to the terminal device corresponds to a third timer), if the second timer starts , start or restart the third timer corresponding to each SCell.

405. If the second condition is met, the terminal device starts a third timer; when the third timer is in a running state, if the third condition is met, the terminal device restarts the third timer.

For related descriptions of the second condition and the third condition, reference may be made to the related descriptions of steps 402 and 403 , and details are not repeated here.

In a possible design, in the case that the third timer is for all SCells configured to the terminal device, if the terminal device receives the PDCCH indicating new transmission from the PCell, or receives any SCell configured to the terminal device of the PDCCH indicating a new transmission, the terminal device starts a third timer.

Monitoring the PDCCH of a serving cell may include at least one of the following: monitoring the PDCCH of the serving cell on the serving cell, and monitoring the PDCCH of the serving cell on other (one or more) serving cells.

Wherein, the PDCCH of a serving cell means that the transmission indicated by the PDCCH is the transmission on the serving cell. For example, the PDCCH of the PCell means that the transmission indicated by the PDCCH is the transmission on the PCell. The PDCCH of the SCell means that the transmission indicated by the PDCCH is the transmission on the SCell. For example, the PDCCH of SCell1 means that the transmission indicated by the PDCCH is the transmission on SCell1.

In a possible design, when the third timer is for all SCells configured to the terminal device, if the third timer is running, the terminal device monitors the PDCCH on all SCells; or monitors the PDCCH of all SCells ; or monitor PDCCH on all SCells and monitor PDCCH on all SCells; if the third timer is not running, the terminal device does not monitor PDCCH on all SCells; or does not monitor PDCCH on all SCells; or does not monitor PDCCH on all SCells and does not Monitor the PDCCH of all SCells.

6) The terminal equipment is in a state of not receiving the PDCCH indicating new transmission after the RAR. Wherein, it indicates that the newly transmitted PDCCH is scrambled by C-RNTI, RAR is a response to the target random access preamble, and the target random access preamble does not belong to the contention-based random access preamble. Optionally, the random access response may be a random access response received on the SCell.

In a possible design, when the third timer is not in the running state, if the first condition is met, the terminal device performs the first processing and the second processing. For the first condition, the first processing, or the second processing, reference may be made to the related description of step 302, and details are not repeated here. When the third timer is in the running state, the terminal device performs the third process.

Exemplarily, as shown in Fig. 4d, it is assumed that a terminal device is configured or activated with one SCell. When the first timer (for example, drx-onDurationTimer), the second timer (for example, drx-InactivityTimer) and the third timer are not running, the terminal device does not monitor the PDCCH. After the first timer starts running, the terminal equipment starts to monitor the PDCCH on the PCell, but does not monitor the PDCCH on the SCell. After the second timer is started, the third timer is started, and the terminal device can monitor the PDCCH on the SCell until the third timer times out. Afterwards, if the second timer restarts, the third timer starts. During the running of the third timer, if the second timer is restarted, the third timer is restarted. During the running of the third timer, the terminal device monitors the PDCCH on the SCell until the third timer times out. At the same time, the terminal device monitors the PDCCH on the PCell during the running of the second timer until the third timer times out.

As shown in Figure 4e, it is assumed that a terminal device is configured or activated with one SCell. When the first timer, the second timer and the third timer are not running, the terminal equipment does not monitor the PDCCH. After the first timer starts running, the terminal equipment starts to monitor the PDCCH on the PCell, but does not monitor the PDCCH on the SCell. If the terminal device receives the PDCCH of a PCell, the third timer is started, and the terminal device monitors the PDCCH on the SCell and/or monitors the PDCCH of the SCell until the third timer expires. After the third timer expires, if the terminal device receives another PCell PDCCH, the third timer starts. When the third timer is running, if the terminal equipment receives the PDCCH of one SCell, the third timer is restarted. During the running of the third timer, the terminal device monitors the PDCCH on the SCell until the third timer times out. It can be understood that when the terminal device receives a PCell PDCCH, the second timer starts; when the terminal device receives another PCell PDCCH during the running of the second timer, the second timer restarts; During the running of the second timer, the PCell detects the PDCCH until the second timer expires.

As shown in Figure 4f, it is assumed that a terminal device is configured or activated with one SCell. When the first timer, the second timer and the third timer are not running, the terminal equipment does not monitor the PDCCH. After the first timer starts running, the terminal device starts to monitor the PDCCH on the PCell, but does not monitor the PDCCH on the SCell and/or does not monitor the PDCCH of the SCell. If the terminal device receives the PDCCH of a PCell, the third timer is started, and the terminal device monitors the PDCCH on the SCell. During the running of the third timer, if the terminal equipment receives the PDCCH of one SCell, the third timer is restarted. During the running of the third timer, the terminal device monitors the PDCCH on the SCell until the third timer times out. After the third timer expires, if the terminal equipment receives a PDCCH of a PCell, the third timer starts, and the terminal equipment monitors the PDCCH on the SCell and/or monitors the PDCCH of the SCell until the third timer expires. It can be understood that the terminal device detects the PDCCH on the PCell during the running of the second timer until the second timer times out.

In the solution provided by the embodiment of the present application, if the third timer is in the running state, the terminal device performs the third processing, for example, monitors the PDCCH on the SCell. That is to say, the duration for the terminal device to monitor the PDCCH on the SCell is determined according to the third timer, thereby avoiding the waste of power consumption caused by the terminal device monitoring the PDCCH on the SCell while monitoring the PDCCH on the PCell in the prior art .
