Description

[0001] This application is a divisional application. The application number of the original application is 201811095995.9, and the original application date is September 19, 2018. The entire content of the original application is incorporated into this application by reference. Technical Field

[0002] The present application relates to the field of communications, and in particular to a wireless communication method and apparatus. Background Art

[0003] In the Long Term Evolution (LTE) communication system, the discontinuous reception (DRX) function is defined. When a terminal device is in the radio resource control (RRC) connected state, DRX can control the terminal device's behavior of monitoring the physical downlink control channel (PDCCH), saving unnecessary power consumption of the terminal device. To further reduce the power consumption of the terminal device monitoring PDCCH, the base station can send an indication information to instruct the terminal device not to monitor PDCCH for the next few time slots.

[0004] In the scenario of carrier aggregation (CA), a terminal device can simultaneously connect to multiple server cells such as the primary cell (PCell) and the secondary cell (SCell). The terminal device can aggregate the carrier units corresponding to multiple server cells such as PCell and SCell to send data, thereby improving the transmission rate.

[0005] However, currently there is no method for designing and sending indication information to reduce the power consumption of the terminal device monitoring the PDCCH in the carrier aggregation scenario. Summary of the Invention

[0069] To make the description of the following embodiments clear and concise, a brief introduction to the relevant concepts or technologies is first given:

[0070] New Radio Access Technical (New RAT or NR) uses the Distributed Response (DRX) mechanism of LTE. New RAT or NR is also referred to as the fifth generation (5G) mobile communication system. A terminal device (e.g., user equipment (UE)) can be configured with DRX functionality while in the RRC Connected state. DRX controls the UE to monitor the PDCCH during certain time periods within a DRX cycle and not monitor the PDCCH during the rest of the time period. Exemplarily, DRX can control the UE to monitor the cell radio network temporary identity (C-RNTI), configured scheduling RNTI (CS-RNTI), interruption RNTI (INT-RNTI), 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 RNTI (TPC-PUSCH-RNTI) or transmit power control sounding reference signal RNTI (TPC-SRS-RNTI) scrambled PDCCH. RNTI is the abbreviation of radio network temporary identity. Since PDCCH can be used to carry DCI, RNTI-scrambled PDCCH can also be understood as RNTI-scrambled DCI. The DCI scrambling process can be to perform cyclic redundancy check (CRC) on the DCI and then scramble the CRC check bits using a radio network temporary identifier; or to perform sequence scrambling on the DCI after the CRC is attached using the RNTI.

[0071] like Figure 1As shown, a DRX cycle includes On Duration and Opportunity for DRX. Among them, OnDuration can be called on-duration, and Opportunity for DRX can be called DRX opportunity. The DRX on-duration timer (drx-onDurationTimer, also called onDurationTimer) can be started at the start time of On Duration (or the start time of DRX Cycle). The duration of drx-onDurationTimer is the duration of OnDuration. The duration of drx-onDurationTimer includes a duration from the start of a DRX cycle. The UE can monitor PDCCH during the On Duration period, that is, the UE can monitor PDCCH during the running period of drx-onDurationTimer. When the UE receives a PDCCH that schedules a new transmission of uplink (uplink, UL) or downlink (downlink, DL) during the running period of drx-onDurationTimer (that is, receives a newly transmitted PDCCH), the inactivity timer (drx-InactivityTimer) can be started (or restarted). The duration of the drx-InactivityTimer includes a duration after the UE receives a PDCCH, for example, it can be a duration after the subframe where the PDCCH is located, or it can be a duration after the PDCCH opportunity where the PDCCH is located. Among them, 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 device to monitor the PDCCH, which can also be called the PDCCH monitoring opportunity. The UE can continue to monitor the PDCCH during the drx-InactivityTimer until the drx-InactivityTimer times out.

[0072] 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, a time window is defined for the uplink and downlink HARQ processes respectively, allowing the UE to start monitoring the uplink or downlink PDCCH after the time window starts from the previous uplink or downlink transmission. This time window can be implemented by a timer. Each uplink HARQ process and each downlink HARQ process can 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 RTTTimer 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 known as drx-ULRetransmissionTimer) is started. For the downlink HARQ process, when the corresponding timer times out, the corresponding downlink retransmission timer (drx-RetransmissionTimerDL, also known as drx-RetransmissionTimer) is started. When drx-RetransmissionTimerUL or drx-RetransmissionTimerDL is running, the UE monitors PDCCH. Among them, drx-RetransmissionTimerUL can be defined as: the maximum duration until a grant for UL retransmission is received (the maximum duration for 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 for receiving a downlink retransmission).

[0073] 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. The active time includes:

[0074] 1) The period of time during which at least one of the following timers is running: drx-onDurationTimer, drx-InactivityTimer, drx-RetransmissionTimerUL, drx-RetransmissionTimerDL, or a contention resolution timer (ra-ContentionResolutionTimer or mac-ContentionResolutionTimer). The contention resolution timer may be used to determine the length of time during which the terminal device monitors the PDCCH indicating message 4 after sending message 3 during the random access process.

[0075] 2) A Scheduling Request (SR) is sent and is pending. When an SR is triggered, it is pending until it is canceled. The period of time during which an SR is pending is the time between the time the SR is sent and the time it is canceled.

[0076] 3) The terminal device has not received a PDCCH scrambled with a C-RNTI indicating a new transmission after successfully receiving a random access response (RAR), wherein the RAR is not the RAR of the random access preamble selected by the UE from the contention-based random access preamble.

[0077] Embodiments of the present application provide a wireless communication method and apparatus for use in a terminal device monitoring or not monitoring a PDCCH during a DRX cycle. For example, this method is used in a carrier aggregation scenario to detect or not monitor a PDCCH on a PCell, as well as in one or more SCells.

[0078] It should be understood that in the scenario of carrier aggregation, the UE maintains an RRC connection with the PCell. During the RRC connection establishment / reestablishment / switching process, the PCell provides non-access stratum (NAS) mobility information, and during the RRC connection establishment / switching process, the PCell provides security input. The UE can also be configured with one or more SCells, which together with the PCell form a serving cell set. The primary component carrier (PCC) corresponding to the PCell and the secondary component carrier (SCC) corresponding to the SCell can be aggregated. The UE can receive or send data on one or more component carriers (CCs) simultaneously according to its capabilities. CC includes PCC and SCC.

[0086] The present application provides a wireless communication method, such as Figure 3 Shown, including:

[0087] 301. A network device sends indication information on a first serving cell.

[0088] The first service cell may be any one of all service cells of the terminal device, and all service cells of the terminal device include the PCell and one or more SCells configured or activated by the terminal device.

[0089] In one possible design, the indication information is used to instruct (the terminal device) not to monitor the PDCCH, which can also be referred to as the indication information being used to instruct (the terminal device) not to expect the PDCCH. Alternatively, the indication information is used to instruct the network device not to send the PDCCH to the terminal device.

[0090] In another possible design, the indication information is used to indicate monitoring of PDCCH.

[0091] Exemplarily, the indication information may include a bit for indicating whether to detect the PDCCH. When the bit is 0, it indicates that the PDCCH is not monitored; when the bit is 1, it indicates that the PDCCH is monitored.

[0092] Exemplarily, the indication information may not include a bit that is explicitly used to indicate whether to detect PDCCH. The indication information may implicitly instruct the terminal device to monitor PDCCH, or the indication information may implicitly instruct the terminal device not to monitor PDCCH. For example, for each service cell in all service cells of the terminal device (for example, the first service cell), if the terminal device does not monitor the PDCCH of the service cell, or does not monitor PDCCH on the service cell, when the terminal device receives the indication information, it may monitor the PDCCH of the service cell according to the indication information, or monitor PDCCH on the service cell. If the terminal device monitors the PDCCH of the service cell, or monitors PDCCH on the service cell, when the terminal device receives the indication information, it may not monitor the PDCCH of the service cell according to the indication information, or not monitor PDCCH on the service cell.

[0093] 302. The terminal device receives indication information on the first serving cell.

[0094] If the indication information is used to instruct not to monitor the PDCCH, the terminal device executes step 303 ; if the indication information is used to instruct to monitor the PDCCH, the terminal device executes step 304 .

[0095] 303. If the indication information is used to indicate not to monitor the PDCCH, the terminal device performs the first processing.

[0096] The first processing includes at least one of the following: not monitoring the PDCCH on the first serving cell; not monitoring the PDCCH on at least one second serving cell; not monitoring the PDCCH of the first serving cell; and not monitoring the PDCCH of at least one second serving cell. It should be understood that when the first serving cell is a PCell, the at least one second serving cell may include a configured or activated SCell of the terminal device. When the first serving cell is an SCell, the at least one second serving cell may include a configured or activated SCell and / or PCell of the terminal device.

[0097] Not monitoring the PDCCH on the first service cell includes at least one of the following: not monitoring the PDCCH of the first service cell on the first service cell; not monitoring the PDCCH of other service cells of the terminal device on the first service cell.

[0098] Not monitoring PDCCH on at least one second service cell means that for each service cell in the at least one second service cell, the PDCCH of the service cell is not monitored in the service cell, or the PDCCH of other service cells of the terminal device is not monitored in the service cell.

[0099] Not monitoring the PDCCH of the first service cell includes at least one of the following: not monitoring the PDCCH of the first service cell on the first service cell; not monitoring the PDCCH of the first service cell on other service cells of the terminal device.

[0100] Not monitoring the PDCCH of at least one second service cell means that for each service cell in the at least one second service cell, the PDCCH of the service cell is not monitored in the service cell, or the PDCCH of the service cell is not monitored in other service cells of the terminal device.

[0101] The PDCCH of a serving cell means that the transmission indicated by the PDCCH is the transmission on the serving cell.

[0102] In one possible design, the indication information may include an index corresponding to the first service cell and / or at least one second service cell. The index of the service cell of the terminal device may be configured by the network device. The index corresponding to the service cell included in the indication information may be the index of the service cell configured by the network device, or an index determined according to the index of the service cell configured by the network device. For example, the index of the service cell configured by the network device is recorded as the first index, and the index of the service cell included in the indication information is recorded as the second index. The service cells of the terminal device are numbered in order of size of the first index (from large to small, or from small to large) to obtain the second index. The service cell of the above-mentioned terminal device may include a PCell and a configured SCell, or only include a configured SCell, or include a PCell and an activated SCell, or only include an activated SCell. For example, when the PCell and the activated SCell of the terminal device are numbered in order of the size of the first index to obtain the second index, the first index of the PCell is 0, and the first indexes of the two activated SCells are 1 and 3 respectively, then the second index of the PCell is 0, the second index of the activated SCell with the first index of 1 is 1, and the second index of the activated SCell with the first index of 3 is 2.

[0103] Alternatively, the indication information includes a bitmap for indicating the first service cell and / or at least one second service cell. For example, the indication information may include a bitmap, each bit corresponding to a service cell, and the length of the bitmap may be the number of the PCell of the terminal device and the configured SCells, or the number of the configured SCells of the terminal device, or the number of the PCell of the terminal device and the activated SCells, or the number of the activated SCells of the terminal device. For example, in the case where the length of the bitmap is the number of the PCell of the terminal device and the configured SCells, if the terminal device is configured with two SCells, the length of the bitmap is 3.

[0104] Optionally, each serving cell of the terminal device corresponds to an index. The serving cells corresponding to the bits in the bitmap can be determined in order of the serving cell indices. Based on the above example, assuming that the PCell index is 0 and the terminal device is configured with two SCell indices of 2 and 4, the first bit in the bitmap can correspond to the PCell, the second bit to the SCell with index 2, and the third bit to the SCell with index 4.

[0105] The length of the bit map can be determined based on the maximum value of the index of the service cell of the terminal device. Optionally, the length of the bit map is the maximum value of the index of the service cell of the terminal device plus 1. For example, if the maximum value of the index of the service cell is 3, the length of the bit map is 4. Furthermore, the first bit in the bit map corresponds to the service cell with an index of 0, the second bit in the bit map corresponds to the service cell with an index of 1, the third bit in the bit map corresponds to the service cell with an index of 2, and the fourth bit in the bit map corresponds to the service cell with an index of 3. The length of the bit map can also be determined based on the maximum number of service cells that can be configured for the terminal device. Optionally, the length of the bit map is the maximum number of service cells that can be configured for the terminal device. For example, when the value of a bit is 1, it indicates that the service cell corresponding to the bit belongs to the first service cell and / or at least one second service cell, that is, the terminal device does not monitor the PDCCH on the service cell corresponding to the bit after receiving the indication information, or does not monitor the PDCCH of the service cell corresponding to the bit.

[0106] In one possible design, if the indication information is used to indicate that the PDCCH is not to be monitored, the indication information also indicates time information for performing the first processing. The time information may include the time length corresponding to each of the first service cell and / or at least one second service cell. For example, assuming that the first service cell is PCell, and the at least one second service cell includes SCell1 and SCell2, PCell, SCell1 and SCell2 may each correspond to a time length, for example, PCell may correspond to 3 time slots, SCell1 may correspond to 2 time slots, and SCell2 may correspond to 1 time slot. Alternatively, the time information may include a time length corresponding to the first service cell and / or at least one second service cell. According to the above example, PCell, SCell1 and SCell2 may correspond to the same time length, for example, PCell, SCell1 and SCell2 all correspond to 3 time slots.

[0107] In one possible design, the terminal device performs the first processing within a first time period after receiving the indication information. The length of the first time period may be determined based on the above-mentioned time information. The first time period may include M time units (time units), where M is an integer greater than or equal to 1. The time unit may be an absolute time, such as seconds, microseconds, milliseconds, etc.; or a symbol, time slot, subframe, etc., which is not limited in this application. The first time period may also include M PDCCH monitoring opportunities, where M is an integer greater than or equal to 1.

[0108] Optionally, the first time period may be configured by the network device. For example, it may be configured through RRC signaling, or it may be indicated in the indication information. In the case where the indication information is used to indicate the first time period, the indication information includes a field indicating the length of the first time period, and the value of the field corresponds one-to-one to each time length in the time length set (including multiple different time lengths). For example, each time length in the time length set corresponds to an index, and the value of the field is the index corresponding to the corresponding time length. Optionally, the time length set may be configured through RRC signaling.

[0109] In one possible design, each of the first service cell and / or at least one second service cell may correspond to a first time period, respectively. The first time period corresponding to each of the first service cell and / or at least one second service cell may be the same or different in duration. In another possible design, the first service cell and / or at least one second service cell may correspond to the same first time period, i.e., the first time period corresponding to each service cell may be the same in duration.

[0110] Optionally, when the first serving cell and / or at least one second serving cell correspond to the same first time period, the terminal device may start a timer after receiving the indication information, and the duration of the timer is the length of the first time period. When the timer runs, the terminal device performs the first processing. For example, Figure 3a As shown, assuming that the first serving cell is a PCell, and at least one second serving cell includes an SCell, the indication information is used to instruct the terminal device not to monitor the PDCCH on the first serving cell and the at least one second serving cell. The PCell and the SCell correspond to the same first time period. After receiving the indication information, the terminal device can start a timer with a duration equal to the length of the first time period. While the timer is running, the terminal device can not monitor the PDCCH on the PCell and the SCell during the first time period.

[0111] Optionally, when each of the first service cell and / or at least one second service cell corresponds to a first time period, the terminal device may simultaneously start a timer corresponding to each service cell after receiving the indication information, and the duration of a timer corresponding to each service cell is the length of the first time period corresponding to the service cell. The terminal device performs the first processing according to the corresponding timer.

[0112] Further, assuming that the terminal device receives an indication message again within the first time period, if the length of the first time period in the indication message received for the first time is the first time length, and the length of the first time period in the indication message received for the second time is the second time length, then one or more of the following situations may be included: a) after the terminal device receives the indication message again, the first processing is performed within the first time period in the indication message received for the second time; b) after the terminal device receives the indication message again, the first processing is completed within the first time period in the indication message received for the first time, and then the first processing is continued within the first time period in the indication message received for the second time; c) after the terminal device receives the indication message again, the first processing is performed within the union of the first time period in the indication message received for the first time and the first time period in the indication message received for the second time. For example, if the first time period in the indication message received for the first time includes the 0th subframe to the 5th subframe, and the first time period in the indication message received for the second time includes the 3rd subframe to the 6th subframe, then the total time period of the first processing includes the 0th subframe to the 6th subframe.

[0113] In one possible design, the terminal device may perform the first processing N time units after receiving the indication information, where N is greater than or equal to 0. The time unit may be an absolute time, such as milliseconds. The time unit may also be a symbol, a time slot, a subframe, etc. The terminal device may also perform the first processing N PDCCH monitoring opportunities after receiving the indication information, where N is greater than or equal to 0.

[0114] In one possible design, if the indication information is used to indicate not to monitor the PDCCH on the first service cell and / or at least one second service cell, the first service cell and / or at least one second service cell include a PCell, and the terminal device does not monitor the PDCCH on all service cells of the terminal device. Alternatively, if the indication information is used to indicate not to monitor the PDCCH of the first service cell and / or at least one second service cell, the first service cell and / or at least one second service cell include a PCell, and the terminal device does not monitor the PDCCH on all service cells of the terminal device. Among them, all service cells of the terminal device include the PCell and one or more SCells configured or activated by the terminal device. The terminal device not monitoring the PDCCH on all service cells can also be understood as the terminal device not monitoring the PDCCH of all service cells.

[0115] In one possible design, after receiving the indication information, the terminal device may not monitor the PDCCH on all service cells within the first time period.

[0116] Optionally, while the terminal device is performing the first processing, it may perform at least one of the following operations: the terminal device does not transmit a channel sounding reference signal (SRS) on the first service cell and / or at least one second service cell; the terminal device does not report channel state information (CSI) on the first service cell and / or at least one second service cell; the terminal device does not transmit a physical uplink control channel (PUCCH) on the first service cell and / or at least one second service cell; the terminal device sets the first service cell and / or at least one second service cell to a deactivated state; the terminal device sets the first service cell and / or at least one second service cell to a sleep state.

[0117] Optionally, after the first time period ends, the UE may perform at least one of the following operations: monitoring PDCCH on the first service cell; monitoring PDCCH on at least one second service cell; monitoring PDCCH of the first service cell; monitoring PDCCH of at least one second service cell.

[0118] Optionally, after the first time period ends, if drx-onDurationTimer is running or drx-InactivityTimer is running, the UE may perform at least one of the following operations: monitoring PDCCH on the first service cell; monitoring PDCCH on at least one second service cell; monitoring PDCCH of the first service cell; monitoring PDCCH of at least one second service cell.

[0119] Optionally, after the first time period ends, if drx-onDurationTimer is not running and drx-InactivityTimer is not running, the UE may perform at least one of the following operations: not monitoring PDCCH on the first service cell; not monitoring PDCCH on at least one second service cell; not monitoring PDCCH of the first service cell; and not monitoring PDCCH of at least one second service cell.

[0120] In one possible design, Figure 3b As shown, if the on-duration timer (i.e., drx-onDurationTimer) is running and the inactivity timer (i.e., drx-InactivityTimer) is not running, the terminal device monitors PDCCH on PCell and / or monitors PDCCH of PCell, and the terminal device does not monitor PDCCH on SCell and / or does not monitor PDCCH of SCell. If drx-InactivityTimer is running, the terminal device performs at least one of the following operations: monitoring PDCCH on PCell; monitoring PDCCH of PCell; monitoring PDCCH on SCell; monitoring PDCCH of SCell. During the operation of drx-InactivityTimer, the terminal device receives indication information on the first service cell, the indication information is used to indicate not to monitor PDCCH, and the terminal device performs a first process within a first time period after receiving the indication information. The first service cell may be a PCell or an SCell, and each of the at least one second service cell may be an SCell.

[0121] 304. If the indication information is used to indicate monitoring of the PDCCH, the terminal device performs a second process.

[0122] The second process includes at least one of the following: monitoring the PDCCH on the first serving cell; monitoring the PDCCH on at least one second serving cell; monitoring the PDCCH of the first serving cell; monitoring the PDCCH of at least one second serving cell.

[0123] Among them, monitoring the PDCCH on the first service cell includes at least one of the following: monitoring the PDCCH of the first service cell on the first service cell; monitoring the PDCCH of other service cells of the terminal device on the first service cell.

[0124] Monitoring the PDCCH on at least one second serving cell means: for each serving cell in the at least one second serving cell, monitoring the PDCCH of the serving cell in the serving cell, or monitoring the PDCCH of other serving cells of the terminal device in the serving cell.

[0125] Monitoring the PDCCH of the first service cell includes at least one of the following: monitoring the PDCCH of the first service cell on the first service cell; monitoring the PDCCH of the first service cell on other service cells of the terminal device.

[0126] Monitoring the PDCCH of the at least one second service cell means: for each service cell in the at least one second service cell, monitoring the PDCCH of the service cell in the service cell, or monitoring the PDCCH of the service cell in other service cells of the terminal device.

[0127] The PDCCH of a serving cell means that the transmission indicated by the PDCCH is the transmission on the serving cell.

[0128] If the indication information is used to indicate monitoring of the PDCCH, the indication information is also used to indicate time information for performing the second process. For the time information, reference may be made to the relevant description of step 303 and will not be repeated here.

[0129] In one possible design, the indication information may include an index corresponding to the first serving cell and / or at least one second serving cell. Alternatively, the indication information includes a bit map for indicating the first serving cell and / or at least one second serving cell. The relevant process can be referred to the description in step 303 and is not repeated here.

[0130] In one possible design, the terminal device performs the second processing within a second time period after receiving the indication information. For the specific process, please refer to the relevant description of the terminal device performing the first processing within the first time period after receiving the indication information in step 303.

[0131] In one possible design, during the second time period, if the drx-onDurationTimer is not running and the drx-InactivityTimer is not running, the UE may perform at least one of the following operations: not monitoring PDCCH on the first service cell; not monitoring PDCCH on at least one second service cell; not monitoring PDCCH of the first service cell; not monitoring PDCCH of at least one second service cell; if the drx-onDurationTimer is running, or the drx-InactivityTimer is running, the UE may perform at least one of the following operations: monitoring PDCCH on the first service cell; monitoring PDCCH on at least one second service cell; monitoring PDCCH of the first service cell; monitoring PDCCH of at least one second service cell.

[0132] In one possible design, the terminal device may perform the second processing N time units after receiving the indication information, where N is greater than or equal to 0. The time unit may be an absolute time, such as milliseconds. The time unit may also be a symbol, a time slot, a subframe, etc. The terminal device may also perform the second processing N PDCCH monitoring opportunities after receiving the indication information, where N is greater than or equal to 0.

[0133] In one possible design, if the indication information is used to indicate monitoring of PDCCH on the first service cell and / or at least one second service cell, the first service cell and / or at least one second service cell include PCell, and the terminal device monitors PDCCH on all service cells of the terminal device. Alternatively, if the indication information is used to indicate monitoring of PDCCH of the first service cell and / or at least one second service cell, the first service cell and / or at least one second service cell include PCell, and the terminal device monitors PDCCH on all service cells of the terminal device. Among them, all service cells of the terminal device include PCell and one or more SCells configured or activated by the terminal device. Monitoring PDCCH on all service cells of the terminal device can also be understood as the terminal device monitoring PDCCH of all service cells.

[0134] In one possible design, after receiving the indication information, the terminal device can monitor the PDCCH on all service cells within the second time period.

[0135] In addition, if the indication information is used to indicate that the PDCCH is not to be monitored, but at least one of the following situations occurs, the terminal device performs the second processing. 1) The downlink retransmission timer is in the running state. For example, the downlink retransmission timer may be drx-RetransmissionTimerDL. 2) The uplink retransmission timer is in the running state. For example, the uplink retransmission timer may be drx-RetransmissionTimerUL. 3) The scheduling request (SR) sent by the terminal device is in a suspended state. 4) The terminal device does not receive a PDCCH indicating a new transmission after successfully receiving a random access response (RAR). Among them, the PDCCH indicating a new transmission is scrambled by the cell radio network temporary identifier C-RNTI, and the RAR is a response to the target random access preamble, and the target random access preamble does not belong to a contention-based random access preamble.

[0136] Optionally, while the terminal device performs the second processing, the terminal device activates the first service cell and / or at least one second service cell.

[0137] Optionally, after the second time period ends, the UE may perform at least one of the following operations: not monitoring PDCCH on the first service cell; not monitoring PDCCH on at least one second service cell; not monitoring PDCCH of the first service cell; not monitoring PDCCH of at least one second service cell.

[0138] Optionally, after the second time period ends, if the drx-onDurationTimer is running or the drx-InactivityTimer is running, the UE may continue to perform the second process.

[0139] Optionally, after the second time period ends, if drx-onDurationTimer is not running and drx-InactivityTimer is not running, the UE may perform at least one of the following operations: not monitoring PDCCH on the first service cell; not monitoring PDCCH on at least one second service cell; not monitoring PDCCH of the first service cell; and not monitoring PDCCH of at least one second service cell.

[0140] In one possible design, Figure 3cAs shown, before the terminal device receives the indication information on the first service cell, if drx-onDurationTimer is running or drx-InactivityTimer is running, the terminal device monitors PDCCH on PCell and / or monitors PDCCH of PCell, and the terminal device does not monitor PDCCH on SCell and / or does not monitor PDCCH of SCell. Assume that during the operation of drx-InactivityTimer, the terminal device receives indication information on the first service cell, and the indication information is used to instruct to monitor PDCCH, and the terminal device performs the second processing within the second time period after receiving the indication information. The first service cell can be PCell or SCell, and each cell in the at least one second service cell can be an SCell.

[0141] Based on the solution provided in the embodiment of the present application, after the terminal device receives the indication information on the first service cell, if the indication information is used to indicate not to monitor the PDCCH, the terminal device can perform the first processing, that is, not to monitor the PDCCH accordingly, thereby reducing the power consumption of the terminal device in monitoring the PDCCH.

[0142] Another embodiment of the present application provides a wireless communication method, such as Figure 4 Shown, including:

[0143] 401. The network device sends indication information on a first serving cell during the running period of a first timer.

[0144] The instruction information can refer to the relevant description of step 301 and will not be repeated here.

[0145] 402. The terminal device receives indication information on the first service cell during the operation of the first timer.

[0146] The first timer is used to determine the length of time the terminal device monitors the PDCCH after receiving the PDCCH. Alternatively, the first timer is used to determine the length of time the terminal device monitors the PDCCH within a DRX cycle. Alternatively, the first timer is used to determine the length of time during the on-duration of a DRX cycle.

[0147] Exemplarily, the first timer may be drx-onDurationTimer or drx-InactivityTimer.

[0148] If the indication information is used to instruct not to monitor the PDCCH, the terminal device executes step 403 ; if the indication information is used to instruct to monitor the PDCCH, the terminal device executes step 404 .

[0149] 403. If the indication information is used to indicate not to monitor the PDCCH, the terminal device performs the first processing.

[0150] After receiving the indication information, the terminal device performs the first processing during the (current) first timer operation, or during the (current) first timer operation and the operation period after the first timer is started n times consecutively, or after the (current) first timer operation and the operation period after the first timer is started n times consecutively, the terminal device performs the first processing. Wherein, n is an integer greater than or equal to 1. For example, n is 2, 3, 4, 5, etc. The first processing can refer to the relevant description of step 303 and is not repeated here.

[0151] For example, Figure 4a As shown, the terminal device receives indication information during the operation of the first timer (for example, drx-onDurationTimer). After receiving the indication information, the terminal device may perform the first processing during the current operation of the drx-onDurationTimer; or perform the first processing during the current operation of the drx-onDurationTimer and during the operation after the drx-onDurationTimer is started n times in succession, that is, during the current operation of the drx-onDurationTimer and the first start of the drx-onDurationTimer (that is, the next start after the end of the current operation of the drx-onDurationTimer) and even the nth start-up period; or perform the first processing after the current operation of the drx-onDurationTimer and during the operation after the drx-onDurationTimer is started n times in succession, that is, after the end of the current operation of the drx-onDurationTimer, perform the first processing during the operation after the drx-onDurationTimer is started for the first time and even after the nth start-up.

[0152] Optionally, when the first timer is drx-onDurationTimer, the UE can perform at least one of the following operations after the drx-onDurationTimer is started for the first time (i.e., the next start after the end of the current drx-onDurationTimer running period) or after the nth start: monitoring PDCCH on the first service cell; monitoring PDCCH on at least one second service cell; monitoring PDCCH of the first service cell; monitoring PDCCH of at least one second service cell.

[0153] If the terminal device receives indication information when drx-onDurationTimer is running and drx-InactivityTimer is not running, the terminal device may perform the first processing after receiving the indication information during the current drx-onDurationTimer is running; or perform the first processing during the current drx-onDurationTimer is running and during the running period after drx-onDurationTimer is started n times continuously; or perform the first processing after the current drx-onDurationTimer is running and during the running period after drx-onDurationTimer is started n times continuously.

[0154] Optionally, after receiving the indication information during the operation of the first timer, the terminal device can stop the first timer and perform the first processing.

[0155] Optionally, the terminal device may stop the first timer N time units after receiving the indication information, where N is greater than or equal to 0. The time unit may be an absolute time, such as milliseconds. The time unit may also be a symbol, a time slot, a subframe, etc. The terminal device may also stop the first timer N PDCCH monitoring opportunities after receiving the indication information, where N is greater than or equal to 0.

[0156] When the first timer is drx-onDurationTimer, the terminal device may stop drx-onDurationTimer after receiving indication information while drx-onDurationTimer is running. Optionally, the terminal device stops drx-onDurationTimer N time units after receiving the indication information. The terminal device may also stop drx-onDurationTimer N PDCCH monitoring opportunities after receiving the indication information.

[0157] In one possible design, if the indication information is used to indicate not to monitor PDCCH on the first service cell and / or at least one second service cell, or if the indication information is used to indicate not to monitor PDCCH of the first service cell and / or at least one second service cell, when the first service cell and / or at least one second service cell include PCell, the terminal device stops the first timer after receiving the indication information; when the first service cell and / or at least one second service cell do not include PCell, the terminal device may not stop the first timer after receiving the indication information.

[0158] For example, when the first timer is drx-onDurationTimer, if the indication information is used to indicate not to monitor PDCCH on the first service cell and / or at least one second service cell, or if the indication information is used to indicate not to monitor PDCCH of the first service cell and / or at least one second service cell, when the first service cell and / or at least one second service cell include PCell, the terminal device stops drx-onDurationTimer after receiving the indication information; when the first service cell and / or at least one second service cell do not include PCell, the terminal device may not stop drx-onDurationTimer after receiving the indication information.

[0159] If the first timer is a drx-InactivityTimer, and the terminal device receives indication information while the drx-InactivityTimer is running, after receiving the indication information, the terminal device may perform the first processing during the current drx-InactivityTimer is running; or perform the first processing during the current drx-InactivityTimer is running and during the running period after the drx-InactivityTimer is started n times continuously; or perform the first processing after the current drx-InactivityTimer is running and during the running period after the drx-InactivityTimer is started n times continuously.

[0160] If the terminal device receives indication information while drx-InactivityTimer is running and drx-onDurationTimer is not running, the terminal device may perform the first processing after receiving the indication information during the current drx-InactivityTimer running period; or perform the first processing during the current drx-InactivityTimer running period and during the running period after drx-InactivityTimer is started n times continuously, or perform the first processing after the current drx-InactivityTimer is run and during the running period after drx-InactivityTimer is started n times continuously.

[0161] If the terminal device receives indication information while the drx-InactivityTimer is running and the drx-onDurationTimer is running, the terminal device may perform the first processing after receiving the indication information during the current drx-InactivityTimer is running; or perform the first processing during the current drx-InactivityTimer is running and during the running period after the drx-InactivityTimer is started n times continuously, or perform the first processing after the current drx-InactivityTimer is running and during the running period after the drx-InactivityTimer is started n times continuously.

[0162] Optionally, after receiving indication information while the drx-InactivityTimer is running, the terminal device may stop the drx-InactivityTimer. The terminal device may stop the drx-InactivityTimer N time units after receiving the indication information. The terminal device may also stop the drx-InactivityTimer N PDCCH monitoring opportunities after receiving the indication information.

[0163] When the first timer is drx-InactivityTimer, if the indication information is used to indicate not to monitor PDCCH on the first service cell and / or at least one second service cell, or if the indication information is used to indicate not to monitor PDCCH of the first service cell and / or at least one second service cell, when the first service cell and / or at least one second service cell include PCell, the terminal device stops drx-InactivityTimer after receiving the indication information; when the first service cell and / or at least one second service cell do not include PCell, the terminal device may not stop drx-InactivityTimer after receiving the indication information.

[0164] Optionally, after the drx-InactivityTimer stops, if the drx-onDurationTimer is running, the UE may perform at least one of the following operations during the running of the drx-onDurationTimer: monitoring the PDCCH on the first serving cell; monitoring the PDCCH on at least one second serving cell; monitoring the PDCCH of the first serving cell; monitoring the PDCCH of at least one second serving cell.

[0165] In one possible design, if the indication information is used to indicate not to monitor the PDCCH on the first service cell and / or at least one second service cell, the first service cell and / or at least one second service cell include a PCell, and the terminal device does not monitor the PDCCH on all service cells of the terminal device. If the indication information is used to indicate not to monitor the PDCCH of the first service cell and / or at least one second service cell, the first service cell and / or at least one second service cell include a PCell, and the terminal device does not monitor the PDCCH on all service cells of the terminal device. Among them, all service cells of the terminal device include the PCell and one or more SCells configured or activated by the terminal device. The terminal device not monitoring the PDCCH on all service cells can also be understood as the terminal device not monitoring the PDCCH of all service cells.

[0166] Optionally, after receiving the indication information, the terminal device may not monitor PDCCH on all service cells during the operation of the first timer, or during the operation of the first timer and after the first timer is started n times consecutively, or after the operation of the first timer and after the first timer is started n times consecutively.

[0167] Optionally, while the terminal device is performing the first processing, it may perform at least one of the following operations: the terminal device does not transmit SRS on the first service cell and / or at least one second service cell, the terminal device does not report CSI on the first service cell and / or at least one second service cell, the terminal device does not transmit PUCCH on the first service cell and / or at least one second service cell; the terminal device sets the first service cell and / or at least one second service cell to a deactivated state; the terminal device sets the first service cell and / or at least one second service cell to a dormant state.

[0168] In one possible design, Figure 4bAs shown, if drx-onDurationTimer is running and drx-InactivityTimer is not running, the terminal device monitors PDCCH on PCell and / or monitors PDCCH of PCell, and the terminal device does not monitor PDCCH on SCell and / or does not monitor PDCCH of SCell. If drx-InactivityTimer is running, the terminal device performs at least one of the following operations: monitoring PDCCH on PCell; monitoring PDCCH of PCell; monitoring PDCCH on SCell; monitoring PDCCH of SCell. During the operation of drx-InactivityTimer, if the terminal device receives indication information on the first service cell, and the indication information is used to indicate not to monitor PDCCH, then after receiving the indication information, the terminal device can perform the first processing during the current operation of drx-InactivityTimer. The first service cell can be PCell or SCell, and each cell in the at least one second service cell can be an SCell.

[0169] 404. If the indication information is used to indicate monitoring of the PDCCH, the terminal device performs a second process.

[0170] After receiving the indication information, the terminal device performs a second process during the (current) running period of the first timer, or during the (current) running period of the first timer and the period after the first timer is started m times consecutively, or after the (current) running period of the first timer and the period after the first timer is started m times consecutively, where m is an integer greater than or equal to 1. The second process can be referred to the relevant description of step 304 and is not repeated here.

[0171] Exemplarily, if the first timer is drx-onDurationTimer, and the terminal device receives indication information during the operation of drx-onDurationTimer, then after receiving the indication information, the terminal device may perform the second processing during the current operation of drx-onDurationTimer; or perform the second processing during the current operation of drx-onDurationTimer and during the operation after drx-onDurationTimer is started n times consecutively; or perform the second processing after the current operation of drx-onDurationTimer and during the operation after drx-onDurationTimer is started n times consecutively.

[0172] Optionally, if the terminal device receives indication information when drx-onDurationTimer is running and drx-InactivityTimer is not running, the terminal device may perform the second processing after receiving the indication information during the current drx-onDurationTimer operation; or during the current drx-onDurationTimer operation and during the operation after drx-onDurationTimer is started n times consecutively, or after the current drx-onDurationTimer operation, during the operation after drx-onDurationTimer is started n times consecutively, the terminal device performs the second processing.

[0173] If the first timer is a drx-InactivityTimer, and the terminal device receives indication information during the running period of the drx-InactivityTimer, the terminal device may perform the second processing after receiving the indication information during the running period of the current drx-InactivityTimer; or perform the second processing during the running period of the current drx-InactivityTimer and after the drx-InactivityTimer is started n times continuously; or perform the second processing after the current drx-InactivityTimer is run and after the drx-InactivityTimer is started n times continuously.

[0174] Optionally, if the terminal device receives indication information when drx-InactivityTimer is running and drx-onDurationTimer is not running, the terminal device may perform the second processing after receiving the indication information during the current drx-InactivityTimer operation period; or during the current drx-InactivityTimer operation period and during the operation period after drx-InactivityTimer is started n times consecutively, or after the current drx-InactivityTimer operation period, during the operation period after drx-InactivityTimer is started n times consecutively, the terminal device performs the second processing.

[0176] In one possible design, if the indication information is used to indicate monitoring of PDCCH on the first service cell and / or at least one second service cell, the first service cell and / or at least one second service cell include PCell, and the terminal device monitors PDCCH on all service cells of the terminal device. Alternatively, if the indication information is used to indicate monitoring of PDCCH of the first service cell and / or at least one second service cell, the first service cell and / or at least one second service cell include PCell, and the terminal device monitors PDCCH on all service cells of the terminal device. Among them, all service cells of the terminal device include PCell and one or more SCells configured or activated by the terminal device. Monitoring PDCCH on all service cells of the terminal device can also be understood as the terminal device monitoring PDCCH of all service cells.

[0177] Optionally, after receiving the indication information, the terminal device may monitor PDCCH on all service cells during the operation of the first timer, or during the operation of the first timer and after the first timer is started n times consecutively, or after the operation of the first timer and after the first timer is started n times consecutively.

[0178] In addition, if the indication information is used to indicate not to monitor the PDCCH, but at least one of the following situations occurs, the terminal device performs the second processing. 1) The downlink retransmission timer is in the running state. For example, the downlink retransmission timer can be drx-RetransmissionTimerDL. 2) The uplink retransmission timer is in the running state. For example, the uplink retransmission timer can be drx-RetransmissionTimerUL. 3) The SR sent by the terminal device is in a suspended state. 4) The terminal device does not receive the PDCCH indicating a new transmission after successfully receiving the RAR. Among them, the PDCCH indicating the new transmission is scrambled by the cell radio network temporary identifier C-RNTI, the 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.

[0179] In addition, after the terminal device receives the indication information during the period when the first timer is not running (for example, before the first timer runs), the terminal device can perform the second processing during the period when the first timer is running, or during the period when the first timer is running and the first timer is started m times in a row, or after the first timer is running and the first timer is started m times in a row.

[0180] Optionally, while the terminal device performs the second processing, the terminal device activates the first service cell and / or at least one second service cell.

[0181] Based on the solution provided in the embodiment of the present application, after the terminal device receives the indication information on the first service cell, if the indication information is used to indicate not to monitor the PDCCH, the terminal device can perform the first processing, that is, not to monitor the PDCCH accordingly, thereby reducing the power consumption of the terminal device in monitoring the PDCCH.
