Description

Wireless communication method and device

Technical Field

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

Background

In a Long Term Evolution (LTE) communication system, a Discontinuous Reception (DRX) function is defined, and when a terminal device is in a Radio Resource Control (RRC) connected (connected) state, the DRX may control the terminal device to monitor a Physical Downlink Control Channel (PDCCH) behavior, so as to save unnecessary power consumption of the terminal device.

In a Carrier Aggregation (CA) scenario, a terminal device may aggregate carrier cells corresponding to multiple server cells, such as a primary cell (PCell) and a secondary cell (SCell), to transmit data, so as to improve a transmission bandwidth. Currently, DRX functionality is targeted at Media Access Control (MAC) entities of the terminal device, i.e. one MAC entity is configured with one DRX functionality, so the terminal device monitors PDCCH on PCell and SCell according to the same DRX parameters, i.e. when the terminal device monitors PDCCH on PCell, it also monitors PDCCH on SCell at the same time.

However, in actual scheduling, the scheduling characteristics on PCell and SCell are typically not the same. For example, more and more frequent scheduling is on PCell and less and sparse scheduling is on SCell. If the time for monitoring the PDCCH on the PCell and the SCell is consistent, when the terminal equipment monitors the PDCCH on the SCell, the terminal equipment rarely receives the PDCCH, so that the power consumption of the terminal equipment is wasted.

Disclosure of Invention

The embodiment of the application provides a wireless communication method and device, which can avoid power consumption waste caused by that terminal equipment monitors a PDCCH on a SCell while monitoring the PDCCH on a PCell in the prior art.

In a first aspect, an embodiment of the present application provides a wireless communication method, including: the terminal equipment receives first information, wherein the first information is used for configuring an SCell of the terminal equipment; if the first condition is met, the terminal equipment performs first processing and second processing; wherein the first condition comprises the first timer being in a running state; the first process includes at least one of: monitoring a PDCCH on the PCell; monitoring a PDCCH of the PCell; the second process includes at least one of: not monitoring the PDCCH on the SCell; the PDCCH of the SCell is not monitored. Based on the scheme, if the first timer is in the running state, the terminal equipment performs first processing and second processing; for example, the terminal device may monitor the PDCCH on the PCell and not monitor the PDCCH on the SCell, so that power consumption waste caused by the terminal device monitoring the PDCCH on the SCell while monitoring the PDCCH on the PCell in the prior art can be avoided.

In one possible implementation, the first condition further includes one or more of the following: the second timer is not in a running state; the second timer is used for determining the time length of monitoring the PDCCH after the terminal equipment receives the PDCCH; the downlink retransmission timer is not in a running state; the uplink retransmission timer is not in a running state; the contention resolution timer is not in a running state; scheduling Request (SR) sent by the terminal device is not in a suspended state; the terminal device is not in a state of not receiving a PDCCH indicating new transmission after successfully receiving a Random Access Response (RAR); the PDCCH indicating the new transmission is scrambled by a cell radio network temporary identity (C-RNTI), and the RAR is a response to a target random access preamble that does not belong to a contention based random access preamble.

In a possible implementation manner, the first timer is used for determining a time length for the terminal device to monitor the PDCCH in one DRX cycle.

In a second aspect, an embodiment of the present application provides a wireless communication method, including: the terminal equipment receives first information, wherein the first information is used for configuring an SCell of the terminal equipment; if the third timer is in the running state, the terminal equipment performs third processing; wherein the third timer is configured to determine a time length of the third process, and the third process includes at least one of: monitoring a PDCCH on the SCell; monitoring the PDCCH of the SCell. Based on the above scheme, if the third timer is in the running state, the terminal device performs a third process, for example, monitors the PDCCH on the SCell. That is to say, the duration that the terminal device performs PDCCH monitoring on the SCell is determined according to the third timer, so that power consumption waste caused by the terminal device monitoring the PDCCH on the SCell while monitoring the PDCCH on the PCell in the prior art can be reduced.

In one possible implementation, the method further includes: if the second condition is met, the terminal equipment starts or restarts the third timer; wherein the second condition comprises any one of: the terminal equipment monitors a PDCCH on a PCell; the terminal equipment monitors a PDCCH of the PCell; the terminal equipment monitors a PDCCH on the SCell; the terminal device monitors the PDCCH of the SCell.

In one possible implementation, the length of the third timer is smaller than the length of the second timer. In this way, since the length of the third timer is smaller than that of the second timer, the duration that the terminal device monitors the PDCCH on the SCell is shorter than the duration that the terminal device monitors the PDCCH on the PCell, thereby reducing power consumption of the PDCCH that the terminal device monitors the SCell.

Detailed Description

For clarity and conciseness of the following description of the various embodiments, a brief introduction to related concepts or technologies is first presented:

the New radio access technology (New RAT or NR) follows the DRX mechanism of LTE. The New RAT or NR may also be referred to as a fifth generation (5G) mobile communication system. A terminal device (e.g., User Equipment (UE)) may be configured with DRX functionality while in an RRC connected state. DRX may control a UE to monitor (monitor) a PDCCH during some periods in one DRX cycle (DRX cycle) and not monitor the PDCCH during the remaining periods. For example, DRX can control UE to monitor C-RNTI, configure scheduling radio network temporary identity (CS-RNTI), intermittent radio network temporary identity (INT-RNTI), slot format indication radio network temporary identity (SFI-RNTI), a semi-static channel state information radio network temporary identifier (SP-CSI-RNTI), a transmission power control radio network temporary identifier (transmit power control RNTI, TPC-PUCCH-RNTI), a transmission power control physical uplink shared channel radio network temporary identifier (transmit power control physical uplink shared channel RNTI, TPC-PUSCH-RNTI) or a transmission power control sounding reference signal radio network temporary identifier (transmit power control sounding reference signal RNTI, TPC-SRS-RNTI). Wherein, the RNTI is an abbreviation of radio network temporary identity (radio network temporary identity). Since PDCCH can be used to carry DCI, RNTI-scrambled PDCCH can also be understood as RNTI-scrambled DCI. The process of scrambling DCI may be to scramble CRC check bits using a radio network temporary identifier after attaching Cyclic Redundancy Check (CRC) to DCI; or scrambling the sequence after CRC attachment of DCI using RNTI.

As shown in fig. 1, one DRX cycle includes On Duration and Opportunity for DRX. Wherein, the On Duration may be referred to as On Duration, and the Opportunity for DRX may be referred to as DRX Opportunity. A DRX On Duration timer (DRX-onDurationTimer, which may also be referred to as onDurationTimer) may be started at the On Duration start time (or DRX Cycle start time). The Duration of the DRX-onDurationTimer is the Duration of the On Duration, i.e. the Duration of the DRX-onDurationTimer comprises a Duration of the start of one DRX cycle. The UE may monitor the PDCCH during the On Duration, i.e., the UE may monitor the PDCCH during the drx-On Duration timer run-time. The inactivity timer (drx-inactivity timer) may be started (or restarted) when the UE receives a PDCCH that schedules a new transmission of Uplink (UL) or Downlink (DL) (i.e., receives a newly transmitted PDCCH) during the drx-onDurationTimer operation period. The duration of drx-inactivity timer includes a duration after the UE receives one PDCCH, for example, a duration after a subframe where the PDCCH is located, or a duration after a PDCCH occasion where the PDCCH is located. Wherein the PDCCH may be used to indicate to the UE a new UL or DL transmission. A PDCCH occasion is a period of time (e.g., one or more symbols) for a terminal device to monitor PDCCH, and may also be referred to as a PDCCH monitoring occasion. The UE may continue to monitor the PDCCH during the drx-inactivity timer operation until the drx-inactivity timer times out.

In addition, when the UE monitors a PDCCH of a hybrid automatic repeat request (HARQ) of data, since there is no fixed timing relationship between a previous transmission and a retransmission, a time window is defined for uplink and downlink HARQ processes (processes), respectively, and the UE is allowed to start monitoring the PDCCH of the uplink or downlink after the time window is continued from the previous uplink or downlink transmission. The time window may be implemented 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 UL HARQ RTT Timer or drx-HARQ-RTT-timerll. The RTT is an abbreviation of Round Trip Time (Round Trip Time). For the uplink HARQ process, when the corresponding timer expires, the corresponding uplink retransmission timer (drx-retransmission timer, which may also be referred to as drx-ul retransmission timer) is started. For the downlink HARQ process, when the corresponding timer expires, the corresponding downlink retransmission timer (drx-retransmission timer, which may also be referred to as drx-retransmission timer) is started. The UE may monitor the PDCCH when drx-retransmission timerll or drx-retransmission timerdl is running. Wherein, drx-retransmission timerll can be defined as: the maximum duration of the uplink transmission grant for UL transmission is received. The drx-retransmission timerdl can be defined as: the maximum duration of time for which a downlink retransmission is received.

When the DRX cycle is configured, the UE may monitor the PDCCH for an Active time (Active time); otherwise, the UE does not need to monitor the PDCCH. Wherein the activation period comprises:

1) a time period during which at least one of the following timers is running: drx-onDurationTimer, drx-inactivytimer, drx-retransmission timerll, or contention resolution timer (ra-contentresulutimer or mac-contentresulutimer). The contention resolution timer may be configured to determine a time length of monitoring the PDCCH for indicating the message four after the terminal device sends the message three in the random access process.

2) A Scheduling Request (SR) is sent and is pending. When an SR is triggered, the SR is on hold until it is cancelled. The SR is in a suspended period, i.e., a period from a time when the SR is transmitted to a time when the SR is cancelled.

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

The embodiment of the application provides a wireless communication method and a wireless communication device, which are applied to the process that terminal equipment monitors a PDCCH or does not monitor the PDCCH in a DRX period. For example, in a scenario applied to carrier aggregation, a terminal device detects or does not monitor a PDCCH on a PCell, and detects or does not monitor a PDCCH on one or more scells. Optionally, the method may be applied to a carrier aggregation scenario, and the terminal device monitors the PDCCH in the power consumption saving mode or does not monitor the PDCCH. It will be appreciated that the network device may send an indication to the terminal device instructing the terminal device to use the power saving mode. Before the network device configures the terminal device to use the power saving mode, the terminal device may send indication information to the network device, for indicating that the terminal device wants to use the power saving mode, or for indicating that the terminal device is low in power.

It should be understood that in a carrier aggregation scenario, the UE maintains an RRC connection with the PCell, the PCell provides non-access stratum (NAS) mobility information during RRC connection establishment/reestablishment/handover, and the PCell provides security input during RRC connection reestablishment/handover. The UE may also be configured with one or more scells, forming a set of serving cells with the PCell. A Primary Component Carrier (PCC) corresponding to the PCell and a Secondary Component Carrier (SCC) corresponding to the SCell may be aggregated. The UE may simultaneously receive or transmit data on one or more Component Carriers (CCs) according to its capability. Wherein, the CC includes PCC and SCC.

Fig. 2 is a schematic diagram of a communication system to which the technical solution provided by the embodiment of the present application is applicable, where the communication system may include a network device 100 and one or more terminal devices 200 (only 1 is shown in fig. 2) connected to the network device 100. The network device may send the PDCCH on the primary cell or the secondary cell (e.g., secondary cell1 or secondary cell 2), and the terminal device may monitor or not monitor the PDCCH sent by the network device on the primary cell or the secondary cell (e.g., secondary cell1 or secondary cell 2), that is, the terminal device may monitor or not monitor uplink and downlink control information sent by the network device on the PDCCH.

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

300. the network equipment sends first information, and the first information is used for configuring the SCell of the terminal equipment.

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

Optionally, the network device may also activate one or more of the configured scells of the terminal device. The network device may also deactivate the activated SCell.

301. The terminal equipment receives first information, and the first information is used for configuring an SCell of the terminal equipment.

The terminal device may receive an RRC message sent by the network device, the RRC message including the first information. The first information is used to configure an SCell of the terminal device. The configured SCell of the terminal device may include one or more, e.g., the terminal device may include 1, 2, or 3 scells.

Optionally, the RRC message may also be used to reconfigure, add, and remove scells for the terminal device.

302. And if the first condition is met, the terminal equipment performs first processing and second processing.

Wherein the first condition comprises the first timer being in a running state. The first timer is used for determining the time length of the terminal equipment for monitoring the PDCCH in one DRX period. For example, the first timer may be a drx-onDurationTimer.

The first process may include at least one of: monitoring a PDCCH on the PCell; monitoring a PDCCH of the PCell. I.e. the first process may include monitoring the PDCCH on the PCell. Alternatively, the first process may include monitoring a 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 process includes at least one of: not monitoring the PDCCH on the SCell; the PDCCH of the SCell is not monitored. I.e. the second process may include not monitoring the PDCCH on the SCell. Alternatively, the second process may include not monitoring the PDCCH of the SCell. Alternatively, the second process may include not monitoring the PDCCH on the SCell and not monitoring the PDCCH of the SCell. The SCell may comprise a configured or activated SCell of a terminal device.

In this embodiment, monitoring PDCCH on one serving cell (e.g. PCell or SCell) may include at least one of the following: the PDCCH of one serving cell is monitored on that cell and the PDCCHs of the other serving cell(s) are monitored on one serving cell. The PDCCH monitoring one serving cell may include at least one of: the PDCCH of the serving cell is monitored on the serving cell and the PDCCH of the serving cell is monitored on the other serving cell(s).

The PDCCH of one serving cell means that the transmission indicated by the PDCCH is on the serving cell. For example, the PDCCH of the PCell means that the transmission indicated by the PDCCH is on the PCell. The PDCCH for the SCell means that the transmission indicated by the PDCCH is on the SCell. For example, the PDCCH of SCell1 means that the transmission indicated by the PDCCH is on SCell 1.

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 PDCCH on both PCell and SCell. When the first timer starts to run, the terminal device performs a first process, for example, monitoring the PDCCH on the PCell, and performs a second process, for example, not monitoring the PDCCH on the SCell.

In one possible design, the first condition further includes one or more of the following:

1) the second timer is not running. Optionally, the second timer corresponding to one SCell may not be in an operating state. Alternatively, the same second timer corresponding to the multiple scells may not be in an active state. The second timer is used for determining the time length of monitoring the PDCCH after the terminal equipment receives the PDCCH, or the second timer is used for determining the time length of monitoring the PDCCH after the terminal equipment receives the PDCCH which indicates new transmission. For example, the second timer may be a Drx-inactivity timer.

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

In addition, if the second timer is in the running state, no matter whether the first timer is in the running state or not, the terminal equipment monitors the PDCCH on the SCell until the second timer is overtime; or the terminal equipment monitors the PDCCH of the SCell until the second timer is overtime; 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 fig. 3b, assume that the UE is configured or activated with one SCell. Before the first timer (e.g., drx-onDurationTimer) is running, the UE does not monitor the PDCCH on both the PCell and SCell. When drx-onDurationTimer starts to run, the UE starts to monitor PDCCH on PCell but not on SCell. When a second timer (e.g., drx-inactivity timer) starts running, the UE starts monitoring the PDCCH on the SCell. The UE may monitor the PDCCH on the SCell until the drx-inactivity timer times out. Optionally, the UE may monitor the PDCCH on the PCell until the drx-inactivity timer times out.

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

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

2) The downlink retransmission timer is not in a running state. For example, the downlink retransmission timer may be drx-retransmission timerdl. 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 in a running state, the terminal device may monitor the PDCCH on the SCell regardless of whether the first timer is in the running state; or monitoring a PDCCH of the SCell; or monitor PDCCH on SCell and PDCCH of SCell. Optionally, if the downlink retransmission timer is in an operating state, the terminal device may monitor the PDCCH on the PCell; or monitoring a 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 in a running state. For example, the uplink retransmission timer may be drx-retransmission timerll. Optionally, the uplink retransmission timer may be an uplink retransmission timer corresponding to an UL HARQ process on the SCell.

In addition, if the uplink retransmission timer is in an operating state, the terminal device may monitor the PDCCH on the SCell regardless of whether the first timer is in the operating state; or monitoring a PDCCH of the SCell; or monitor PDCCH on SCell and PDCCH of SCell. Optionally, if the uplink retransmission timer is in an operating state, the terminal device may monitor the PDCCH on the PCell; or monitoring a 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 in a running state. Optionally, the contention resolution timer may be a contention resolution timer corresponding to the SCell.

In addition, if the contention resolution timer is in the running state, the terminal device may monitor the PDCCH on the SCell regardless of whether the first timer is in the running state; or monitoring a PDCCH of the SCell; or monitor PDCCH on SCell and PDCCH of SCell. Optionally, if the contention resolution timer is in an operating state, the terminal device may monitor the PDCCH on the PCell; or monitoring a PDCCH of the PCell; or monitor the PDCCH on the PCell and monitor the PDCCH of the PCell.

5) A Scheduling Request (SR) sent by the terminal device is not in a suspended state. Optionally, the scheduling request may be a scheduling request transmitted on the SCell.

In addition, if the SR sent by the terminal device is in a suspended state, the terminal device may monitor the PDCCH on the SCell regardless of whether the first timer is in an operating state; or monitoring a PDCCH of the SCell; or monitor PDCCH on SCell and PDCCH of SCell. Optionally, if the SR sent by the terminal device is in a suspended state, the terminal device may monitor the PDCCH on the PCell; or monitoring a 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 a state of not receiving a PDCCH indicating a new transmission after successfully receiving a Random Access Response (RAR). Wherein, the PDCCH indicating the new transmission is scrambled by the C-RNTI, the RAR is a response to the target random access preamble, and the target random access preamble does not belong to the random access preamble based on competition. 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, the terminal device may monitor the PDCCH on the SCell regardless of whether the first timer is in the running state; or monitoring a PDCCH of the SCell; or monitor PDCCH on SCell and PDCCH of SCell. Optionally, if the terminal device does not receive the PDCCH indicating the new transmission after successfully receiving the RAR, the terminal device may monitor the PDCCH on the PCell; or monitoring a PDCCH of the PCell; or monitor the PDCCH on the PCell and monitor the PDCCH of the PCell.

Illustratively, in one possible case, if the first timer is in a running state and the second timer is not in a running state, the terminal device performs the first processing and the second processing. In another possible case, if the first timer is in an operating state and the second timer and the downlink retransmission timer are not in an operating state, the terminal device performs the first processing and the second processing. In another possible case, if the first timer is in an operating state and the second timer, the downlink retransmission timer, and the uplink retransmission timer are not in an operating state, the terminal device performs the first processing and the second processing.

Optionally, while the terminal device performs the second processing, one or more of the following operations may be performed: the terminal device does not transmit a Channel Sounding Reference Signal (SRS) on the SCell, the terminal device does not report Channel State Information (CSI) on the SCell, the terminal device does not transmit a Physical Uplink Control Channel (PUCCH) on the SCell, the terminal device sets the SCell in a sleep State and the terminal device sets the SCell in a deactivation State.

In the prior art, a terminal device monitors a PDCCH on a PCell and an SCell according to the same DRX parameters. Since the terminal device monitors the PDCCH on the SCell with little chance of receiving the PDCCH, power consumption of the terminal device is wasted. Based on the scheme provided by the embodiment of the application, when the first timer is in the running state, the terminal equipment can not monitor the PDCCH on the SCell and/or does not monitor the PDCCH of the SCell, so that the power consumption of monitoring the PDCCH by the terminal equipment is reduced.

Yet another embodiment of the present application provides a wireless communication method, as shown in fig. 4, including:

400. the network equipment sends first information, and the first information is used for configuring the SCell of the terminal equipment.

401. The terminal equipment receives first information, and the first information is used for configuring an SCell of the terminal equipment.

The first information may refer to the related description of step 301, and is not described herein again.

In one possible design, after the terminal device receives the first information, any one of steps 402 to 405 may be optionally executed to start or restart the third timer. Wherein the third timer is used for determining the time length of the third processing. The terminal device performs a third process during the running of the third timer, and the third process refers to the related description of step 406 below.

402. And if the second condition is met, the terminal equipment starts or restarts the third timer.

Wherein the second condition comprises any one of: the terminal equipment monitors a PDCCH on the PCell; the terminal equipment monitors the PDCCH on the SCell; the terminal equipment monitors a PDCCH of the PCell; and the terminal equipment monitors the PDCCH of the SCell. For example, if the terminal device monitors the PDCCH on the PCell; or if the terminal equipment monitors the PDCCH on the SCell; or if the terminal equipment monitors the PDCCH of the PCell; or if the terminal device monitors 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. And when the third timer does not run, if the terminal equipment receives the PDCCH of the PCell, starting the third timer, and performing third processing by the terminal equipment during the running period of the third timer until the third timer is overtime. And then, if the terminal equipment receives the PDCCH of the PCell again, starting a third timer. And in the operation of the third timer, if the terminal equipment receives the PDCCH of the SCell, restarting the third timer. And the terminal equipment performs third processing during the running period of the third timer until the third timer is overtime.

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

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

403. And if the third condition is met, the terminal equipment starts or restarts the third timer.

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

For example, as shown in fig. 4b, it is assumed that the terminal device is configured or activated one SCell. And when the third timer does not run, if the terminal equipment receives the PDCCH of the SCell, the third timer is started, and the terminal equipment performs third processing during the running period of the third timer. During the operation of the third timer, if the terminal device receives the PDCCH of the SCell, the third timer is restarted. And the terminal equipment performs third processing during the running period of the third timer until the third timer is overtime.

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

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

Optionally, if the terminal device monitors the PDCCH on the PCell, the terminal device may not operate the third timer, that is, the third timer is not started or restarted.

404. And if the second timer is started or restarted, the terminal equipment starts or restarts the third timer.

The second timer is used for determining the time length of the terminal equipment for performing the fourth processing after receiving the PDCCH. The fourth process includes at least one of: monitoring a PDCCH on the PCell; monitoring a PDCCH of the PCell. That is, the fourth process may include monitoring the PDCCH on the PCell. Alternatively, the fourth process may include monitoring a PDCCH of the PCell. Alternatively, the fourth process may include monitoring the PDCCH on the PCell and monitoring the PDCCH of the PCell. The relevant process may refer to the relevant description in step 302, which is not described herein.

Illustratively, the second timer may be a drx-inactivity timer. If the drx-inactivity timer is started or restarted, the third timer is started or restarted. For example, as shown in fig. 4c, it is assumed that the terminal device is configured or activated one SCell. If drx-inactivity timer is started (for example, drx-inactivity timer starts to operate after the terminal device receives a PDCCH on the PCell), the third timer is started. The terminal equipment performs fourth processing during the running period of the second timer until the second timer is overtime; and the terminal equipment performs third processing during the running period of the third timer until the third timer is overtime. After the third timer expires, if the drx-inactivity timer is restarted (for example, after the terminal device receives one PDCCH in the PCell during the drx-inactivity timer operation, the drx-inactivity timer is restarted), the third timer is started. During the third timer running, if the drx-inactivity timer is restarted, the third timer is restarted. And the running period of the third timer of the terminal equipment carries out third processing until the third timer is overtime.

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. 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 smaller than that of the second timer, the duration that the terminal device monitors the PDCCH on the SCell is shorter than the duration that the terminal device monitors the PDCCH on the PCell, thereby reducing power consumption of the PDCCH that the terminal device monitors the SCell.

In one possible design, in case the third timer is for all scells, the terminal device starts or restarts the third timer if the second timer starts.

In a possible design, in a case that the third timer is for one SCell (one third timer for each SCell among all scells configured to the terminal device), if the second timer is started, the third timer corresponding to each SCell is started or restarted.

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

The description of the second condition and the third condition may refer to the description of steps 402 and 403, which is not described herein.

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

In a possible design, in a case that the third timer is for a certain SCell (i.e., one third timer is respectively corresponding to each SCell among all scells configured to the terminal device), if the terminal device receives a PCell or a PDCCH indicating new transmission for the SCell, the terminal device starts the third timer corresponding to the SCell.

406. And if the third timer is in the running state, the terminal equipment performs third processing.

The third process includes at least one of: monitoring a PDCCH on the SCell; monitoring the PDCCH of the SCell. For example, the third processing includes monitoring a PDCCH on the SCell, or the third processing includes monitoring a PDCCH of the SCell; or the third process includes monitoring the PDCCH on the SCell and monitoring the PDCCH of the SCell.

In one possible design, in the case that the third timer is for all scells configured for the terminal device, if the third timer is running, the terminal device monitors PDCCHs on all scells; or monitoring the PDCCH of all SCells; or monitoring the PDCCH on all SCells and monitoring the PDCCH of all SCells; if the third timer is not running, the terminal equipment does not monitor the PDCCH on all SCells; or not monitoring the PDCCHs of all SCells; or not monitoring PDCCH on all scells and not monitoring PDCCH of all scells. If the third timer runs when the third timer is for a certain SCell configured to the terminal device, the terminal device monitors a PDCCH on the SCell, or monitors a PDCCH of the SCell, or monitors a PDCCH on the SCell and monitors a PDCCH of the SCell; if the third timer is not running, the terminal device does not monitor the PDCCH on the SCell, or does not monitor the PDCCH of the SCell, or does not monitor the PDCCH on the SCell and does not monitor the PDCCH of the SCell.

Optionally, if the third timer is in an operating state, the terminal device may monitor the PDCCH on the PCell. Alternatively, the PDCCH of the PCell is monitored. Or, monitoring the PDCCH on the PCell and monitoring the PDCCH of the PCell. The specific process may refer to the related description in step 302, which is not described herein.

In one possible embodiment, the terminal device performs the third processing if the third timer is not in an operating state but at least one of the following conditions occurs.

1) The first timer (e.g., drx-onDurationTimer) is in a running state.

Optionally, the drx-onDurationTimer corresponding to one SCell may be in an operating state. Alternatively, the same drx-onDurationTimer corresponding to the scells may be in an operating state. For example, when the first timer is in an operating state, if a drx-onDurationTimer corresponding to an SCell is in an operating state, the terminal device monitors a PDCCH on the SCell and/or the terminal device monitors a PDCCH of the SCell; if the same drx-onDurationTimer corresponding to the plurality of scells is in the operating state, the terminal device monitors the PDCCH on the plurality of scells and/or the terminal device monitors the PDCCH of the plurality of scells.

2) The downlink retransmission timer is in a running state. For example, the downlink retransmission timer may be drx-retransmission timerdl. Optionally, the downlink retransmission timer may be a downlink retransmission timer corresponding to a DL HARQ process on the SCell.

3) The uplink retransmission timer is in a running state. For example, the uplink retransmission timer may be drx-retransmission timerll. Optionally, the uplink retransmission timer may be an uplink retransmission timer corresponding to an UL HARQ process on the SCell.

4) The contention resolution timer is in a running state. Optionally, the contention resolution timer may be a contention resolution timer corresponding to the SCell.

5) The SR transmitted by the terminal device is in a suspended state. Optionally, the scheduling request may be a scheduling request transmitted on the SCell.

6) The terminal equipment is in a state that the terminal equipment does not receive the PDCCH indicating the new transmission after the RAR. Wherein, the PDCCH indicating the new transmission is scrambled by the C-RNTI, the RAR is a response to the target random access preamble, and the target random access preamble does not belong to the random access preamble based on competition. 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 satisfied, the terminal device performs the first processing and the second processing. The first condition, the first process or the second process may refer to the related description of step 302, which is not described herein again. And when the third timer is in the running state, the terminal equipment performs third processing.

Exemplarily, as shown in fig. 4d, it is assumed that the terminal device is configured or activated with one SCell. When none of the first timer (e.g., drx-onDurationTimer), the second timer (e.g., drx-inactivity timer), and the third timer are running, the terminal device does not monitor the PDCCH. When the first timer starts running, the terminal device starts monitoring the PDCCH on the PCell, but does not monitor the PDCCH on the SCell. When the second timer is started, a third timer is started, and the terminal device may monitor the PDCCH on the SCell until the third timer expires. And then, if the second timer is restarted, the third timer is started. And in the running process of the third timer, if the second timer is restarted, the third timer is restarted. The terminal device monitors the PDCCH on the SCell during operation of the third timer until the third timer expires. Meanwhile, the terminal device monitors the PDCCH on the PCell until the third timer times out during the operation of the second timer.

As shown in fig. 4e, it is assumed that the terminal device is configured or activated one SCell. When the first timer, the second timer and the third timer are not running, the terminal device does not monitor the PDCCH. When the first timer starts running, the terminal device starts monitoring the PDCCH on the PCell, but does not monitor the PDCCH on the SCell. And if the terminal equipment receives a PDCCH of the PCell, starting a third timer, and monitoring the PDCCH on the SCell and/or monitoring the PDCCH of the SCell by the terminal equipment until the third timer is overtime. And after the third timer is overtime, if the terminal equipment receives a PDCCH of the PCell again, the third timer is started. And in the running process of the third timer, the terminal equipment receives the PDCCH of one SCell, and the third timer is restarted. The terminal device monitors the PDCCH on the SCell during operation of the third timer until the third timer expires. It can be understood that, when the terminal device receives a PDCCH of one PCell, the second timer is started; when the terminal equipment receives a PDCCH of a PCell again during the running period of the second timer, the second timer is restarted; and the terminal equipment detects the PDCCH in the PCell during the running of the second timer until the second timer is overtime.

As shown in fig. 4f, it is assumed that the terminal device is configured or activated one SCell. When the first timer, the second timer and the third timer are not running, the terminal device does not monitor the PDCCH.

And during the running of the third timer, the terminal equipment receives the PDCCH of one SCell, and the third timer is restarted. The terminal device monitors the PDCCH on the SCell during operation of the third timer until the third timer expires. And after the third timer is overtime, if the terminal equipment receives a PDCCH of a PCell, starting the third timer, and monitoring the PDCCH on the SCell and/or monitoring the PDCCH of the SCell by the terminal equipment until the third timer is overtime. It can be understood that the terminal device detects the PDCCH at the PCell during the operation of the second timer until the second timer times out.

In the solution provided in the embodiment of the present application, if the third timer is in an operating state, the terminal device performs a third process, for example, monitors the PDCCH on the SCell. That is to say, the duration that the terminal device performs PDCCH monitoring on the SCell is determined according to the third timer, so that power consumption waste caused by the terminal device monitoring the PDCCH on the SCell while monitoring the PDCCH on the PCell in the prior art can be avoided.
