Description

Wireless communication method and device

Technical Field

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

Background

In a long term evolution (long term evolution, LTE) communication system, a discontinuous reception (discontinuous reception, DRX) function is defined, and when a terminal device is in a radio resource control (radio resource control, RRC) connected state, DRX can control the terminal device to monitor the behavior of a physical downlink control channel (physical downlink control channel, PDCCH), so as to save unnecessary power consumption of the terminal device.

In the scenario of carrier aggregation (carrier aggregation, CA), the terminal device may aggregate carrier units corresponding to a plurality of server cells, such as a primary cell (PCell) and a secondary cell (SCell), to transmit data, so as to improve the transmission bandwidth. Currently, the DRX function is for a medium access control (media access control, MAC) entity of the terminal device, i.e. one MAC entity is configured with one DRX function, so the terminal device monitors the PDCCH on the PCell and the SCell according to the same DRX parameters, i.e. when the terminal device monitors the PDCCH on the PCell, the PDCCH is also monitored on the SCell.

However, in actual scheduling, the scheduling features on the PCell and SCell are typically not the same. For example, more and more frequently scheduled on the PCell and less and sparser scheduled on the SCell. If the time for monitoring the PDCCH is consistent between the PCell and the SCell, when the terminal equipment monitors the PDCCH in the SCell, the PDCCH is rarely received, 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 the power consumption waste caused by monitoring PDCCH on an SCell when the PCell monitors PDCCH 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 includes the first timer being in an operational state; the first process includes at least one of: monitoring PDCCH on PCell; monitoring PDCCH of the PCell; the second process includes at least one of: not monitoring PDCCH on SCell; the PDCCH of the SCell is not monitored. Based on the scheme, if the first timer is in an operation 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 the power consumption waste caused by the terminal device monitoring the PDCCH on the SCell while the PCell monitors the PDCCH 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 an operating state; the second timer is used for determining the time length of the PDCCH monitored by the terminal equipment after receiving the PDCCH; the downlink retransmission timer is not in an operating state; the uplink retransmission timer is not in an operating state; the contention resolution timer is not in an operational state; the scheduling request (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 a new transmission after successful reception of a random access response (random access response, RAR); the PDCCH indicating the new transmission is scrambled by a cell radio network temporary identity (cell radio network temporary identity, C-RNTI), the RAR being a response to a target random access preamble that does not belong to a contention based random access preamble.

In one possible implementation, the first timer is used to determine a length of time that the terminal device monitors PDCCH during 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 an operation state, the terminal equipment performs third processing; wherein the third timer is for determining a length of time for the third process, the third process comprising at least one of: monitoring PDCCH on SCell; the PDCCH of the SCell is monitored. Based on the above scheme, if the third timer is in an operation state, the terminal device performs a third process, for example, monitoring the PDCCH on the SCell. That is, the duration of the terminal device for PDCCH monitoring in the SCell is determined according to the third timer, so that the power consumption waste caused by the terminal device monitoring the PDCCH on the SCell while the PCell monitors the PDCCH 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 includes any one of: the terminal equipment monitors PDCCH on the PCell; the terminal equipment monitors PDCCH of the PCell; the terminal equipment monitors PDCCH on the SCell; the terminal device monitors the PDCCH of the SCell.

In one possible implementation, the length of the third timer is less 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 of the terminal device for monitoring the PDCCH on the SCell is smaller than that of the terminal device for monitoring the PDCCH on the PCell, thereby reducing the power consumption of the terminal device for monitoring the PDCCH of the SCell.

Based on the above scheme, when the third timer is not in the running state and the first timer is in the running state, the terminal device may perform the first process and the second process; for example, the terminal device may monitor the PDCCH on the PCell and not monitor the PDCCH on the SCell, so that the power consumption waste caused by the terminal device monitoring the PDCCH on the SCell while the PCell monitors the PDCCH in the prior art can be avoided.

Detailed Description

For clarity and conciseness in the description of the embodiments below, a brief introduction to related concepts or technologies is first given:

the New radio access (New radio access technical, new RAT or NR) has adopted the DRX mechanism of LTE. Among them, the New RAT or NR may also be referred to as a fifth generation (the fifth generation, 5G) mobile communication system. A terminal device (e.g., a User Equipment (UE)) may be configured with a DRX function in an RRC connected state. DRX may control the UE to monitor (listen to) the PDCCH for some periods in one DRX cycle (DRX cycle) and not to monitor the PDCCH for the remaining periods. For example, the DRX may control a UE monitor C-RNTI, a configured scheduling radio network temporary identifier (configured scheduling RNTI, CS-RNTI), a discontinuous radio network temporary identifier (INT-RNTI), a slot format indication radio network temporary identifier (slot format indication RNTI, SFI-RNTI), a semi-static channel state information radio network temporary identifier (semi-persistent CSI RNTI, 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) scrambled PDCCH. Wherein, the RNTI is short for radio network temporary identifier (radio network temporary identity). Since PDCCH may be used to carry DCI, RNTI scrambling PDCCH may also be understood as RNTI scrambling DCI. Wherein, the scrambling DCI can be that after DCI is attached with cyclic redundancy check (cyclic redundancy check, CRC), the wireless network temporary identifier is used for scrambling CRC check bits; or scrambling the sequence after the DCI CRC attachment using RNTI.

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

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

When the DRX cycle is configured, the UE may monitor the PDCCH for an Active period (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-InactivityTimer, drx-RetransmissionTimerUL, drx-retransmission timer dl or contention resolution timer (ra-contentioresolute or mac-contentioresolute). The contention resolution timer may be used to determine a time length of the PDCCH for indicating the message four after the terminal device transmits the message three in the random access procedure.

2) A scheduling request (Scheduling Request, SR) is sent and pending (pending). When an SR is triggered, the SR is on hold until it is cancelled. The SR is in a period between a time when the SR is transmitted and a time when the SR is cancelled.

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

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

It should be appreciated that in the context of carrier aggregation, the UE maintains an RRC connection with the PCell, which provides non-access stratum (NAS) mobility information during RRC connection establishment/reestablishment/handover, and which provides security input during RRC connection reestablishment/handover. The UE may also be configured with one or more scells, together with the PCell, to form a set of serving cells. The primary carrier (primary component carrier, PCC) corresponding to the PCell and the secondary carrier (secondary component carrier, SCC) corresponding to the SCell may be aggregated. The UE may receive or transmit data on one or more component carriers (component Carriers, CCs) simultaneously according to its capabilities. Wherein the CC includes PCC and SCC.

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

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

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

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 the SCell of the terminal device. The configured scells of the terminal device may comprise one or more, for example, the terminal device may comprise 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 the first processing and the second processing.

Wherein the first condition includes the first timer being in an operational state. The first timer is used for determining the time length of the PDCCH monitored by the terminal device in one DRX period. For example, the first timer may be drx-onDurationTimer.

The first process may include at least one of: monitoring PDCCH on PCell; the PDCCH of the PCell is monitored. I.e. the first process may comprise monitoring PDCCH on PCell. Alternatively, the first process may include monitoring a PDCCH of the PCell. Alternatively, the first process may include monitoring PDCCH on the PCell and monitoring PDCCH of the PCell.

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

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

Wherein, the PDCCH of a serving cell refers to that the transmission indicated by the PDCCH is a transmission on the serving cell. For example, PDCCH of PCell refers to transmission of the PDCCH indication being transmission on PCell. The PDCCH of an SCell refers to the transmission indicated by the PDCCH being a transmission on the SCell. For example, the PDCCH of SCell1 refers to the transmission indicated by the PDCCH being a transmission on SCell 1.

For example, as shown in fig. 3a, it is assumed that the terminal device is configured or activated with one SCell. The terminal device may not monitor PDCCH on both PCell and SCell until the first timer runs. When the first timer starts running, the terminal device performs a first process, e.g. monitoring PDCCH on the PCell, and a second process, e.g. not monitoring 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 in an operational state. Alternatively, it may be that a second timer corresponding to the SCell is not in an operating state. Alternatively, the same second timer corresponding to the plurality of scells may not be in an operating state. The second timer is used for determining the time length of the PDCCH monitored by the terminal equipment after receiving the PDCCH, or determining the time length of the PDCCH monitored by the terminal equipment after receiving the PDCCH indicating the new transmission. For example, the second timer may be a Drx-InactivityTimer.

For example, if the second timer corresponding to one SCell is not in an operating state, when the first timer is in an operating 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 the plurality of scells is not in the running state, when the first timer is in the running state, the terminal device can monitor the PDCCH on the PCell, and not monitor the PDCCH on the plurality of scells. For another example, if the second timer corresponding to one SCell is not in an operating state, when the first timer is in an operating 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 plurality of scells is not in the running state, when the first timer is in the running state, the terminal device can monitor the PDCCH of the PCell and does not monitor the PDCCH of the plurality of scells.

In addition, if the second timer is in the running state, 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 PDCCH of the SCell until the second timer is overtime; or the terminal device monitors PDCCH on the SCell and monitors 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. Until a first timer (e.g., drx-onduration timer) runs, the UE does not monitor PDCCH on both PCell and SCell. After drx-onduration timer starts running, the UE starts monitoring PDCCH on PCell but does not monitor PDCCH on SCell. After a second timer (e.g., drx-InactigitTimer) starts running, the UE starts monitoring PDCCH on the SCell. The UE may monitor PDCCH on SCell until drx-inactivity timer times out. Alternatively, the UE may monitor PDCCH on PCell until drx-incaactyitytimer times out.

In one possible design, the terminal device may start or restart the second timer if the terminal device monitors PDCCH on the PCell or SCell, or if the terminal device monitors PDCCH on the PCell or SCell indicating a new transmission. Optionally, if the terminal device monitors the PDCCH on the PCell or one SCell, the terminal device may start or restart the 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 an operational state. For example, the downlink retransmission timer may be drx-retransmission timer dl. Alternatively, 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 an operation state, the terminal device can monitor the PDCCH on the SCell no matter whether the first timer is in the operation state; alternatively, monitoring the PDCCH of the SCell; or monitoring PDCCH on SCell and monitoring PDCCH of SCell. Optionally, if the downlink retransmission timer is in an operation state, the terminal device may monitor the PDCCH on the PCell; alternatively, monitoring PDCCH of PCell; or monitoring PDCCH on the PCell and monitoring PDCCH of the PCell.

3) The uplink retransmission timer is not in an operating state. For example, the uplink retransmission timer may be drx-retransmission timer ul. Alternatively, 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 operation state, the terminal device can monitor the PDCCH on the SCell no matter whether the first timer is in the operation state or not; alternatively, monitoring the PDCCH of the SCell; or monitoring PDCCH on SCell and monitoring PDCCH of SCell. Optionally, if the uplink retransmission timer is in an operation state, the terminal device may monitor the PDCCH on the PCell; alternatively, monitoring PDCCH of PCell; or monitoring PDCCH on the PCell and monitoring PDCCH of the PCell.

4) The contention resolution timer is not in an operational state. Alternatively, the contention resolution timer may be a contention resolution timer corresponding to the SCell.

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

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

In addition, if the SR transmitted by the terminal device is in a suspended state, whether the first timer is in an operating state or not, the terminal device may monitor the PDCCH on the SCell; alternatively, monitoring the PDCCH of the SCell; or monitoring PDCCH on SCell and monitoring PDCCH of SCell. Optionally, if the SR transmitted by the terminal device is in a suspended state, the terminal device may monitor the PDCCH on the PCell; alternatively, monitoring PDCCH of PCell; or monitoring PDCCH on the PCell and monitoring PDCCH of the PCell.

6) The terminal device is not in a state of not receiving a PDCCH indicating a new transmission after successful reception of the random access response (Random Access Response, RAR). Wherein the PDCCH indicating the new transmission is scrambled by the C-RNTI, and the RAR is a response to the target random access preamble, which does not belong to the contention-based random access preamble. Alternatively, 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 an operating state; alternatively, monitoring the PDCCH of the SCell; or monitoring PDCCH on SCell and monitoring 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; alternatively, monitoring PDCCH of PCell; or monitoring PDCCH on the PCell and monitoring PDCCH of the PCell.

For example, in one possible case, if the first timer is in an operating state and the second timer is not in an operating state, the terminal device performs the first process and the second process. In yet another possible scenario, 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 yet another possible scenario, 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 channel sounding reference signals (Sounding Reference Signal, SRS) on the SCell, the terminal device does not report channel state information (Channel State Information, CSI) on the SCell, the terminal device does not transmit physical uplink control channels (Physical Uplink Control Channel, PUCCH) on the SCell, the terminal device sets the SCell to a dormant state and the terminal device sets the SCell to a deactivated state.

In the prior art, a terminal device monitors PDCCH on a PCell and an SCell according to the same DRX parameters. The terminal equipment rarely receives the PDCCH when monitoring the PDCCH in the SCell, so that the power consumption of the terminal equipment 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 not monitor the PDCCH of the SCell, so that the power consumption of the terminal equipment for monitoring the PDCCH is reduced.

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

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

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

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

In one possible design, after the terminal device receives the first information, any one of steps 402-405 may be optionally performed to start or restart the third timer. Wherein the third timer is for determining a length of time for the third process. The terminal device performs a third process during the third timer run, the third process being described with reference to step 406 below.

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

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

For example, as shown in fig. 4a, it is assumed that the terminal device is configured or activated with one SCell. When the third timer is not running, if the terminal equipment receives the PDCCH of the PCell, the third timer is started, and the terminal equipment performs third processing 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. In the third timer operation, if the terminal device receives the PDCCH of the SCell, the third timer is restarted. The terminal device performs a third process during the third timer run until the third timer expires.

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

In one possible design, if the third timer is specific to a certain SCell configured to the terminal device (i.e. each SCell in all scells configured to the terminal device corresponds to a third timer, respectively), if the terminal device receives the PCell or a PDCCH indicating a new transmission of the SCell, 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 the third timer.

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

For example, as shown in fig. 4b, it is assumed that the terminal device is configured or activated with one SCell. And when the third timer is not operated, if the terminal equipment receives the PDCCH of the SCell, the third timer is started, and the terminal equipment performs third processing during the operation 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. The terminal device performs a third process during the third timer run until the third timer expires.

In one possible design, if the third timer is for all scells configured for 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 SCell.

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

Optionally, if the terminal device monitors the PDCCH on the PCell, the terminal device may not operate the third timer, i.e. not start or restart the third timer.

404. 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 fourth processing of the terminal equipment after receiving the PDCCH. The fourth process includes at least one of: monitoring PDCCH on PCell; the PDCCH of the PCell is monitored. I.e. the fourth process may comprise monitoring PDCCH on PCell. Alternatively, the fourth process may include monitoring PDCCH of the PCell. Alternatively, the fourth process may include monitoring PDCCH on the PCell and monitoring PDCCH of the PCell. The correlation process may refer to the correlation description in step 302, and will not be described herein.

The second timer may be, for example, drx-InactivityTimer. If the drx-InactigityTimer 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 with one SCell. If the drx-inactivity timer starts (for example, after the terminal device receives a PDCCH on the PCell, the drx-inactivity timer starts running), the third timer starts. The terminal equipment performs fourth processing during the operation of the second timer until the second timer is overtime; the terminal device performs a third process during the third timer run until the third timer expires. After the third timer expires, if the drx-inactivity timer is restarted (for example, after the terminal device receives a PDCCH at the PCell during the operation of the drx-inactivity timer, the drx-inactivity timer is restarted), the third timer is started. During the third timer run, if drx-InactivityTimer is restarted, the third timer is restarted. The terminal device performs a third process during the third timer run until the third timer expires.

Optionally, the length of the third timer is less 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 of the terminal device for monitoring the PDCCH on the SCell is smaller than that of the terminal device for monitoring the PDCCH on the PCell, thereby reducing the power consumption of the terminal device for monitoring the PDCCH of the SCell.

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

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

405. If the second condition is met, the terminal equipment starts a third timer; and when the third timer is in an operation state, if the 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 are not described herein.

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

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

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

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

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

Optionally, if the third timer is in an operation state, the terminal device may monitor the PDCCH on the PCell. Alternatively, the PDCCH of the PCell is monitored. Alternatively, the PDCCH is monitored on the PCell and the PDCCH of the PCell is monitored. Specific procedures may refer to the related descriptions in step 302, and will not be described herein.

In one possible configuration, the terminal device performs the third process if the third timer is not in operation, but at least one of the following occurs.

1) The first timer (e.g., drx-onduration timer) is in an operational state.

Alternatively, a drx-onduration timer corresponding to an SCell may be in an operating state. Or, the same drx-onduration timer corresponding to multiple scells may be in an operating state. For example, when the first timer is in the non-running state, if the drx-onduration timer corresponding to one SCell is not in the running state, the terminal device monitors the PDCCH in the SCell and/or the terminal device monitors the PDCCH of the SCell; if the same drx-onduration timer corresponding to a plurality of scells is not in an operation state, the terminal device monitors the PDCCH in the plurality of scells and/or monitors the PDCCH of the plurality of scells.

2) The downlink retransmission timer is in an operational state. For example, the downlink retransmission timer may be drx-retransmission timer dl. Alternatively, 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 an operating state. For example, the uplink retransmission timer may be drx-retransmission timer ul. Alternatively, 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 an operational state. Alternatively, 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. Alternatively, the scheduling request may be a scheduling request transmitted on the SCell.

6) The terminal device is in a state that no PDCCH indicating a new transmission is received after the RAR. Wherein the PDCCH indicating the new transmission is scrambled by the C-RNTI, and the RAR is a response to the target random access preamble, which does not belong to the contention-based random access preamble. Alternatively, the random access response may be a random access response received on the SCell.

In one possible configuration, the terminal device performs the first and second processing if the first condition is satisfied when the third timer is not in operation. The first condition, the first process, or the second process may refer to the related description of step 302, which is not described herein. And when the third timer is in an operation state, the terminal equipment performs third processing.

Illustratively, as shown in fig. 4d, it is assumed that the terminal device is configured or activated with one SCell. The terminal device does not monitor the PDCCH when neither the first timer (e.g., drx-onduration timer) nor the second timer (e.g., drx-incarvitytimer) is running. After the first timer starts running, the terminal device starts monitoring PDCCH on the PCell, but does not monitor PDCCH on the SCell. When the second timer starts, the third timer starts, and the terminal device may monitor the PDCCH on the SCell until the third timer times out. Then, if the second timer is restarted, the third timer is started. During the operation 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 the third timer run until the third timer expires. Meanwhile, the terminal device monitors the PDCCH on the PCell during the second timer run until the third timer expires.

As shown in fig. 4e, it is assumed that the terminal device is configured or activated with one SCell. When neither the first timer nor the second timer nor the third timer is running, the terminal device does not monitor the PDCCH. After the first timer starts running, the terminal device starts monitoring PDCCH on the PCell, but does not monitor PDCCH on the SCell. If the terminal equipment receives the PDCCH of one PCell, the third timer is started, and the terminal equipment monitors the PDCCH on the SCell and/or monitors the PDCCH of the SCell until the third timer is overtime. After the third timer times out, if the terminal equipment receives a PDCCH of one PCell, the third timer is started. In the third timer running, if the terminal device receives a PDCCH of one SCell, the third timer is restarted. The terminal device monitors the PDCCH on the SCell during the third timer run until the third timer expires. It can be appreciated that the second timer starts when the terminal device receives the PDCCH of one PCell; when the terminal equipment receives the PDCCH of one PCell again during the operation of the second timer, the second timer is restarted; the terminal device detects the PDCCH at the PCell during operation of the second timer until the second timer expires.

As shown in fig. 4f, it is assumed that the terminal device is configured or activated with one SCell. When neither the first timer nor the second timer nor the third timer is running, the terminal device does not monitor the PDCCH. After the first timer starts running, the terminal device starts monitoring PDCCH on the PCell, but does not monitor PDCCH on the SCell and/or does not monitor PDCCH of the SCell. If the terminal equipment receives the PDCCH of one PCell, the third timer is started, and the terminal equipment monitors the PDCCH on the SCell. During the operation of the third timer, if the terminal device receives a PDCCH of one SCell, the third timer is restarted. The terminal device monitors the PDCCH on the SCell during the third timer run until the third timer expires. After the third timer is overtime, if the terminal equipment receives the PDCCH of one PCell, the third timer is started, and the terminal equipment monitors the PDCCH on the SCell and/or monitors the PDCCH of the SCell until the third timer is overtime. It can be appreciated that the terminal device detects the PDCCH at the PCell during the second timer run until the second timer expires.

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