In a mobile communication system, a network device may configure a discontinuous reception (discontinuous reception, DRX) communication mode for a terminal device in a radio resource control (radio resource control, RRC) connected state, where the terminal device only needs to detect control information for a period of time when performing the DRX communication mode, and is in a sleep state for other periods of time without detecting control information. The RRC-connected terminal device also needs to complete tasks such as co-frequency signal quality measurement and inter-frequency signal quality measurement configured by the network device, and multiple tasks may conflict, so that the terminal device processes a corresponding solution.

In a first aspect, a communication method is provided, which may be performed by a terminal device or a module (e.g. a chip or a chip module) configured in (or for) the terminal device. The following description will take an example in which the terminal device executes the method.
The method comprises the following steps: the terminal device determines that a period in which the second period overlaps with a third period within one discontinuous reception DRX cycle overlaps in the first period. The second time period includes one or more of a measurement interval, a time period in which the physical downlink control channel PDCCH is omitted from detection, and an uplink resource time period, where the measurement interval is used to measure signal quality of the inter-frequency cell, and the third time period is a time period in which the PDCCH is detected in the DRX cycle determined according to the network device configuration. And the terminal device detects the PDCCH in a fourth period of time within the DRX period, the fourth period of time being a period of time other than the first period of time in the third period of time.
According to the scheme, the terminal equipment and the network equipment can achieve consensus, and resource waste caused by the fact that the network equipment transmits the PDCCH in a time period when the terminal equipment does not detect the PDCCH due to the fact that the consensus is not achieved is reduced. The resource utilization rate can be improved.
The second time period is, for example, a measurement interval, the terminal device measures the signal quality of the inter-frequency cell in the second time period. Or the second time period is a time period in which the PDCCH is omitted from being detected, and the terminal device does not detect the PDCCH in the second time period. And if the second time period is the uplink resource time period, the terminal equipment is in a signal sending state and does not receive signals in the uplink resource time period.
That is, the network device configures the priority of the task executed by the terminal device in the second period to be higher than the priority of the PDCCH detection in the DRX cycle, and the terminal device and the network device may determine which task the terminal device specifically executes in the overlapping period of the tasks according to the task priority, so as to reduce the probability that the internal logic confusion occurs in the terminal device, resulting in a crash or the like.

The terminal device operates the DRX timer in a second operation time period in the DRX period to detect the PDCCH in the second operation time period. The network device determines a period of time in which the terminal device actually operates the timer, that is, a period of time in which the terminal device detects the PDCCH, in the same manner as the terminal device, and transmits the PDCCH to the terminal device in the period of time. The terminal equipment and the network equipment can agree with each other on the PDCCH detection of the terminal equipment, so that the resource waste is reduced, and the resource utilization rate is improved.

Or if the ending time of the second time period is within the first operation time period and the starting time of the first operation time period to the ending time of the second time period are smaller than the second time period, the terminal equipment determines that the operation time period of the DRX timer in the DRX period is the second operation time period.

Fig. 1 is only a schematic diagram, and other network devices may be further included in the communication system, for example, a wireless relay device and a wireless backhaul device may also be included, which are not shown in fig. 1.
The radio access network device is an access device to which the terminal accesses the communication system by wireless. The radio access network device may be a base station (base station), an evolved NodeB (eNodeB), a transmission and reception point (transmission reception point, TRP), a next generation NodeB (gNB) in a 5G mobile communication system, a next generation base station in a 6G mobile communication system, a base station in a future mobile communication system, or an access node in a WiFi system, etc.; the present application may also be a module or unit that performs a function of a base station part, for example, a Central Unit (CU) or a Distributed Unit (DU).

Of course, communication between 110a and 120i may be performed via an interface protocol between base stations, and in this case, 120i is also a base station with respect to 110 a.

In order for a terminal to communicate with a base station, it is necessary to establish a radio connection with a cell controlled by the base station.

It should be understood that in the embodiment of the present application, the physical downlink shared channel (physical downlink SHARED CHANNEL, PDSCH), the physical downlink control channel (physical downlink control channel, PDCCH), and the Physical Uplink Shared Channel (PUSCH) are merely examples of downlink data channels, downlink control channels, and uplink data channels, respectively, and the data channels and the control channels may have different names in different systems and different scenarios, and the embodiment of the present application is not limited thereto.
The following is a description of related art and terms related to embodiments of the present application.
1. Connected mode discontinuous reception (CDRX)
For the terminal device, the radio resource control (radio resource control, RRC) may configure the medium access control (medium access control, MAC) entity to implement CDRX function, that is, to implement discontinuous detection control of the physical downlink control channel (physical downlink control channel, PDCCH) of the terminal device, so as to achieve the goal of saving power consumption of the terminal device in the RRC connected state. In the RRC connection state, if the DRX is configured, the MAC entity performs discontinuous detection of the DRX activation maintenance control PDCCH according to a DRX timer, otherwise, performs continuous detection of the PDCCH according to a protocol.
In the DRX mechanism, two timers mainly control the terminal device to enter into the active state of DRX, which is a first timer (which may be referred to as onduration timer) and a second timer (DRX-INACTIVITYTIMER), as shown in fig. 2, where the onduration timer starts to operate at the start time of each DRX cycle, the operation duration is a period of time configured by the network device and less than the DRX cycle, the terminal device is in an awake state in an onduration timer operation period in one DRX cycle and detects the PDCCH, and may be in a dormant state in a time other than the onduration timer operation period, without detecting the PDCCH, so as to achieve the purpose of saving power consumption of the DRX mechanism. If the terminal equipment successfully receives one PDCCH for scheduling uplink primary transmission data or downlink primary transmission data in the activation time, the drx-INACTIVITYTIMER is started, and the PDCCH is continuously detected in the running time of the drx-INACTIVITYTIMER, so that the data can be continuously transmitted, and the transmission delay of service data caused by the fact that the terminal equipment enters a dormant state under the condition that the data transmission is not completed is reduced. For example, as shown in fig. 2, after the terminal device successfully detects one PDCCH for scheduling uplink or downlink primary data in the running time of onduration timer (i.e., the first timer) in the DRX cycle n, the terminal device starts DRX-INACTIVITYTIMER (i.e., the second timer), and the terminal device continues to detect the PDCCH in the running time of DRX-INACTIVITYTIMER. And the terminal device does not detect the PDCCH in the running time of the onduration timer in the DRX cycle n+1, and the terminal device may stop detecting the PDCCH to enter the sleep state after the running time of the onduration timer is ended. The primary transmission data refers to data transmitted between the terminal device and the network device for the first time, which may also be referred to as new transmission data, and if the receiving end does not successfully receive the primary transmission data, the transmitting end may send the data to the receiving end again, and the data that is sent again may be referred to as retransmission data.
2. Omitting detection PDCCH (PDCCH skip)
The network device can send control information omitting the detection of the PDCCH to the terminal device through the PDCCH, and the terminal device does not detect the PDCCH for a period of time according to the indication of the control information so as to achieve the purpose of saving power consumption.
Aiming at the situation that a plurality of tasks executed by a network device are conflicted and the execution time of the plurality of tasks is overlapped, the embodiment of the application provides that the task priority can be set, so that the terminal device and the network device can determine which task the terminal device specifically executes in the overlapped time period of the plurality of tasks according to the task priority, thereby reducing the probability of internal logic confusion of the terminal device and causing the situations of dead halt and the like. The terminal equipment and the network equipment can be agreed, and resource waste caused by the fact that the agreement is not achieved is reduced. The resource utilization rate can be improved.
Fig. 3 is a schematic flow chart of a communication method 300 provided by an embodiment of the present application. The communication method 300 may be performed by a terminal device or a device (e.g., a chip or a chip module) configured in the terminal device, and the terminal device is described below as an example of performing the method 300, which should be understood that the present application is not limited thereto. The method 300 includes, but is not limited to, the steps of:
S301, the terminal device determines that a second period overlaps with a third period in one DRX cycle in the first period, where the second period includes one or more of a measurement interval, a period in which the PDCCH is detected is omitted, or an uplink resource period, and the third period is a period in which the PDCCH is detected in the DRX cycle determined according to the network device configuration.
The network device configures the terminal device with a DRX communication mode through the configuration information, and the terminal device may determine a third period, which is a period of time for the network device to configure the terminal device to detect the PDCCH in the DRX cycle according to the configuration information.
The network device may further configure or instruct the terminal device with other tasks, where the second time period during which the network device configures the terminal device to perform other tasks may overlap with the third time period, i.e. multiple tasks performed by the network device configuring the terminal device may collide, and the terminal device first determines the first time period during which the second time period overlaps with the third time period. As shown in fig. 4, a third period of time for detecting the PDCCH in the DRX cycle determined by the terminal device according to the configuration of the network device overlaps with a second period of time for the network device to configure the terminal device to perform other tasks in the first period of time.
The second period may include one or more of a measurement interval, a period in which the PDCCH is detected is omitted, and an uplink resource period.
In one example, the network device configures a measurement interval (measurement gap) for the terminal device, and the second period may include the measurement interval, where the measurement interval is used for signal quality measurement of an inter-frequency cell, and the terminal device needs to measure signal quality measurement of a cell (referred to as an inter-frequency cell) other than a serving cell according to a frequency band (referred to as an inter-frequency or an inter-frequency band) other than an operating frequency band configured within the measurement interval. The measurement interval may be periodic, and illustratively the measurement interval may be 6ms and the period may be 40ms, the network device configures the terminal device to measure the signal quality of the inter-frequency cell within the first 6ms measurement interval of every 40 ms. The measurement interval configured by the network device for the terminal device may overlap with a period of time during which the terminal device detects the PDCCH in the DRX cycle determined based on the configuration of the network device.
In another example, the network device indicates to the terminal device a period of omitting to detect the PDCCH, and the second period may include the period of omitting to detect the PDCCH, that is, the period of omitting to detect the PDCCH may overlap with a third period of detecting the PDCCH in the DRX cycle determined by the terminal device according to the network device configuration.
In yet another example, the network device may configure a frame format for the terminal device, i.e., the network device configures uplink resources and downlink resources for the terminal device in a communication frame in which the network device communicates with the terminal device. The second period may include an uplink resource period, that is, the uplink resource period may overlap with a period in which the terminal device detects the PDCCH in the DRX cycle determined based on the network device configuration.
The second time period may include processing time periods of at least two tasks, and the terminal device may determine a time period in which the third time period overlaps with the at least two time periods as the first time period. It should be understood that each time period in the present application may be continuous or discontinuous, and the present application is not limited thereto.
S302, the terminal device detects the PDCCH in a fourth period of time within the DRX cycle, the fourth period of time being a period of time other than the first period of time in the third period of time.
For example, as shown in fig. 5, after determining in S301 that the second period overlaps the third period, the terminal device does not detect the PDCCH in the first period and detects the PDCCH in the fourth period that does not overlap the second period. That is, the terminal device detects the PDCCH only for the fourth period of time within the DRX cycle. Accordingly, the network device may determine the first time period, and thus the fourth time period, in the same manner as the terminal device. The network device determines that the terminal device detects the PDCCH only in the fourth period of time in the DRX cycle, and if the network device needs to send the PDCCH to the terminal device, the network device may send the PDCCH to the terminal device in the fourth period of time in the DRX cycle. The network device does not transmit the PDCCH to the terminal device for a period other than the fourth period in the DRX cycle. The terminal equipment and the network equipment can achieve consensus, and resource waste caused by the fact that the network equipment transmits the PDCCH in a time period when the terminal equipment does not detect the PDCCH due to the fact that the consensus is not achieved is reduced. The resource utilization rate can be improved.
That is, the priority of the task of the terminal device detecting the PDCCH during the DRX cycle is lower than that of other tasks, which may include, but are not limited to, one or more of measuring signal quality during a measurement interval, omitting to detect the PDCCH, or transmitting a signal on an uplink resource. When the task of detecting the PDCCH in the DRX period configured by the network equipment for the terminal equipment is overlapped with the time period for executing other tasks, the terminal equipment executes the task with high priority in the overlapped time period because the priority of the task for detecting the PDCCH in the DRX period is lower than that of the other tasks. Alternatively, the priority of the terminal device for performing the various tasks may be pre-configured by the network device or pre-defined by the protocol.
In one embodiment, the third period of time comprises an operational period of a DRX timer configured by the network device. The operation period of the DRX timer is a period in which the terminal device detects the PDCCH. The terminal device determines a first period in S401, including: the terminal device determines a fifth time period in which the second time period overlaps the first operation time period, the first time period including the fifth time period. And the terminal equipment determines the operation time period of the DRX timer in the DRX period to be a second operation time period according to the first operation time period and the fifth time period, wherein the second operation time period is a time period except the fifth time period in the first operation time period. The terminal device detects the PDCCH in a fourth time period, including: the terminal device operates the DRX timer for a second operation period within the DRX cycle, and detects a PDCCH when the DRX timer is operated.
And the terminal equipment judges the time period of detecting the PDCCH in the DRX period by maintaining the running and stopping of the timer. The terminal device detects the PDCCH in the running time period of the timer, the timer stops running, and the terminal device does not detect the PDCCH. The terminal device may determine, according to the configuration information from the network device, that the operation period of the timer configured by the network device for the terminal device is the first operation period. And the terminal device may determine a second time period for the network device to configure the terminal device to perform other tasks (e.g., one or more of inter-frequency cell measurement, omission of detection of PDCCH or uplink resource configuration), thereby determining that the second time period of the first time period of operation that does not overlap the second time period is an actual time period of operation of the timer. The terminal device operates a timer for a second operation period within the DRX cycle and detects the PDCCH when the timer is operated. And not running the timer in a time period except the second running time period in the DRX period, and when the timer stops running, not detecting the PDCCH by the terminal equipment. Wherein the fifth time period, which includes the terminal device in the first operation time period of the network device configuration, does not operate the timer. The network device determines the time period of the timer actually operated by the terminal device in the same manner as the terminal device, so that the terminal device and the network device agree on the terminal device to detect the PDCCH.
As an example and not by way of limitation, the DRX timer comprises a first timer and/or a second timer, wherein the first run time period of the first timer is a time period starting at a start time of a DRX cycle configured by the network device. The first operation period of the second timer is a period after the terminal device receives the PDCCH for indicating the uplink (a new UL transmission) or downlink (a new DL transmission), and the duration of the first operation period of the second timer is configured by the network device.
For example, as shown in fig. 6, the network device configures the terminal device to perform inter-frequency cell measurement in a second period of time, where the second period of time is a measurement interval. The measurement interval overlaps with an operation period 1 (i.e., an example of a first operation period) of a first timer (i.e., onduration timer in the foregoing) within one DRX cycle configured by the network device, the terminal device may determine that an operation period 2 (i.e., an example of a second period) where the operation period 1 and the measurement interval do not overlap is an actual operation period of the onduration timer, the terminal device operates the onduration timer in the operation period 2 within the DRX cycle, and monitors the PDCCH during operation, other periods do not detect the PDCCH within the DRX cycle, and a period during which the terminal device detects the PDCCH may be in a sleep state, which may reduce power consumption. And the terminal device measures the signal quality of the inter-frequency cell according to the configuration of the network device in the second time period.
For another example, if the terminal device does not perform other tasks in the running period 1 of the onduration timer configured by the network device, as shown in fig. 7, the terminal device runs the onduration timer in the running period 1, and if the terminal device successfully receives a PDCCH during the running of the onduration timer, the terminal device needs to start a second timer (i.e., DRX-INACTIVITYTIMER in the foregoing), and the measurement interval configured by the network device for the terminal device is in the DRX cycle, the terminal device needs to determine whether the running period 3 (i.e., another example of the first period) of the DRX-INACTIVITYTIMER configured by the network device overlaps with the measurement interval, and if so, the terminal device determines that the running period 3 of DRX-INACTIVITYTIMER does not overlap with the second period is the actual running period of DRX-INACTIVITYTIMER, i.e., the running period 4 of DRX-INACTIVITYTIMER (i.e., another example of the second running period), and the terminal device continues to detect the PDCCH during the running period 4.
For another example, if the terminal device determines that the running period 2 of the onduration timer is overlapped with the running period 1 of the onduration timer, and the terminal device successfully receives the PDCCH in the running period 2, the terminal device determines whether the running period 3 of the drx-INACTIVITYTIMER overlaps with a period (for example, the measurement interval or other task period) in which the network device configures the terminal device to perform other tasks, and if so, the terminal device determines the actual running period of the drx-INACTIVITYTIMER, that is, the running period 4.
The second period of time may also be an uplink resource period configured by the network device. As shown in fig. 8, the network device configures a frame format for the terminal device, where the frame format includes a downlink resource for carrying a downlink signal sent by the network device to the terminal device, i.e., a downlink time unit as shown in fig. 8, and an uplink resource for carrying an uplink signal sent by the terminal device to the network device, i.e., an uplink time unit as shown in fig. 8, and a special resource between the downlink resource and the uplink resource, i.e., a special time unit as shown in fig. 8, where the special time unit includes a time when the terminal device performs downlink-to-uplink conversion (i.e., the terminal device converts from a received signal state to a transmitted signal state). Illustratively, the time unit may be a time domain symbol, a slot, a subframe, or a frame. The running period of the onduration timer configured by the network device is running period 1, where the running period 1 overlaps with the uplink resource period (including 6 uplink time units) configured by the network device, the terminal device may determine that running period 2 where the running period 1 does not overlap with the uplink resource period is an actual running period of the onduration timer, and the terminal device runs the onduration timer in the running period 2 and detects the PDCCH when the onduration timer runs. Accordingly, the network device may determine, according to the frame format, an operation period 2 in which the terminal device detects the PDCCH, and if the PDCCH needs to be sent to the terminal device, the network device sends the PDCCH to the terminal device in the operation period 2. According to the scheme, after the terminal equipment is configured with the DRX mode, when the uplink resource time period configured by the network equipment is overlapped with the running time period of the onduration timer configured by the network equipment, the network equipment cannot send the PDCCH because the overlapped time period belongs to the uplink resource time period, so that the terminal equipment can not detect that the PDCCH enters the dormant state in the overlapped time period, unnecessary power consumption of the terminal equipment can be reduced, consensus can be achieved with the network equipment, and the utilization rate of communication resources can be improved.
If the terminal device onduration timer successfully receives the PDCCH from the network device in the actual running time, the terminal device needs to start drx-INACTIVITYTIMER, and the terminal device can determine whether the running time period 3 configured by drx-INACTIVITYTIMER overlaps with the uplink resource time period according to the frame structure, if so, the terminal device determines that the running time period 3 does not overlap with the uplink resource time period, for example, the running time period 4, which is the actual running time period of drx-INACTIVITYTIMER, and the terminal device detects the PDCCH in the actual running time period of drx-INACTIVITYTIMER. Accordingly, the network device may determine the operation period 4 in the same manner after transmitting the PDCCH, and the network device may transmit the PDCCH to the terminal device in the operation period 4.
The second period may also be a period indicated by the network device in which the PDCCH is detected omitted. As shown in fig. 9, the terminal device operates onduration timer in DRX cycle n, detects PDCCH when onduration timer operates, and successfully detects one PDCCH, the control information carried by the PDCCH indicates the period of time for which the terminal device omits to detect PDCCH, and the terminal device determines the period of time for which the terminal device omits to detect PDCCH as shown in fig. 9 according to the control information. And the terminal device needs to start drx-INACTIVITYTIMER after receiving the PDCCH successfully, the terminal device can determine whether the running period 3 of drx-INACTIVITYTIMER configured by the network device overlaps with a period of omitting the detection of the PDCCH, if the terminal device determines the running period 4 of the running period 3 which does not overlap with the period of omitting the detection of the PDCCH, runs drx-INACTIVITYTIMER in the running period 4, and detects the PDCCH when drx-INACTIVITYTIMER runs. The terminal device may stop running onduration timer and drx-INACTIVITYTIMER at the start time of the period of omitting the detection of PDCCH as shown in fig. 9, without detecting PDCCH in the period of omitting the detection of PDCCH. If the period of omitting the PDCCH detection overlaps with the running period of the onduration timer configured by the network device in the next DRX cycle (i.e., DRX cycle n+1), the terminal device may determine the actual running period of the onduration timer in DRX cycle n+1, and run the onduration timer in the actual running period. The network equipment adopts the same mode to determine the time period of the terminal equipment for detecting the PDCCH, so that the terminal equipment and the network equipment can achieve consensus, unnecessary power consumption is reduced, and the resource utilization rate is improved.
In one embodiment, the DRX timer includes a first timer, and the terminal device determines a period of time for performing pre-synchronization corresponding to the DRX cycle according to a second operation period of the first timer.
Before the terminal equipment wakes up to enter an active state in a DRX period, the terminal equipment needs to be pre-synchronized with the network equipment so that the terminal equipment can calibrate the synchronization of time and frequency with the network equipment to improve the accuracy of detecting the PDCCH. When the terminal device determines that the starting time of the second operation time period of the onduration timer is different from the starting time of the first operation time period of the first timer, the terminal device may determine a time period for performing pre-synchronization corresponding to the DRX cycle according to the second operation time period of the onduration timer, and after the terminal device completes pre-synchronization with the network device in the time period, detect the PDCCH in the second operation time period.
In one embodiment, the terminal device determines an operation period of the DRX timer within the DRX cycle as a second operation period, including: if the starting time of the second time period is within the first operation time period and the starting time of the second time period to the ending time of the first operation time period are smaller than the second time period, the terminal equipment determines that the operation time period of the DRX timer in the DRX period is the second operation time period.
That is, in the case where the start time of the second period is within the first operation period and the end time of the first operation period is within the second period, the terminal device determines the second operation period of the DRX timer. This causes the terminal device to determine the second operating period of the DRX timer as a continuous period.
In another embodiment, the determining, by the terminal device, the operation period of the target timer in the DRX cycle as the second operation period includes: if the ending time of the second time period is within the first operation time period and the starting time of the first operation time period to the ending time of the second time period are smaller than the second time period, the terminal equipment determines that the operation time period of the target timer in the DRX period is the second operation time period.
That is, in the case where the end time of the second period is within the first operation period and the start time of the first operation period is within the second period, the terminal device determines the second operation period of the DRX timer. The terminal device is caused to determine the second operating period of the DRX timer as a continuous period.
If the starting time of the second time period is within the first operation time period and the ending time of the first operation time period is not within the second time period, or if the ending time of the second time period is within the first operation time period and the starting time of the first operation time period is not within the second time period, the terminal device operates the DRX timer in the operation time period (i.e., the first operation time period) of the DRX timer configured by the network device.
According to the embodiment of the application, the task priority can be set, so that the terminal equipment and the network equipment can determine which task the terminal equipment specifically executes in the overlapping time period of a plurality of tasks according to the task priority, and the probability of internal logic confusion of the terminal equipment and the occurrence of dead halt and other conditions is reduced. The terminal equipment and the network equipment can reach consensus, and resource waste caused by the fact that the network equipment transmits the PDCCH in a time period when the terminal equipment does not detect the PDCCH due to the fact that the consensus is not reached is reduced. The resource utilization rate can be improved.
Fig. 10 is a schematic flowchart of a communication method 1000 provided in an embodiment of the present application, and the method 1000 is described below by taking a terminal device as an example, which should be understood that the present application is not limited thereto. The method 1000 includes, but is not limited to, the steps of:
s1001, the terminal device determines that the uplink resource period overlaps with a sixth period in a seventh period, where the sixth period is a period configured by the network device for measuring signal quality of a synchronization signal block of a serving cell and/or for measuring signal quality of a synchronization signal block of a cell other than the serving cell.
Illustratively, the synchronization signal block is a synchronization signal and physical broadcast signal block (SSB). The sixth time period may be a time period for measuring signal quality of the serving cell and/or neighbor cells determined according to the SSB measurement time configuration (SSB measurement timing configuration, SMTC).
S1002, the terminal device measures the signal quality of the synchronization signal block in an eighth period, which is a period other than the seventh period in the sixth period.
If the sixth time period overlaps with the uplink resource time period configured by the network device in the seventh time period, the terminal device considers that the seventh time period is the uplink resource time period and is not used for measuring the downlink signal from the network device, and therefore, the terminal device only measures the signal quality of the synchronization signal block in the eighth time period which does not overlap with the uplink resource time period in the sixth time period. The terminal device does not measure the signal quality of the synchronization signal block for the seventh period. According to the scheme, when the uplink resource time period configured by the network device and the time period of the downlink signal (i.e. the synchronous signal block) measured by the terminal device have uplink and downlink conflicts in a seventh time period, the terminal device considers that the seventh time period is the uplink resource time period, that is, the priority of the uplink resource configuration is higher than the priority of the SMTC, so that the terminal device can determine the purpose of the configuration conflict time period, and the probability of the terminal device failure caused by the configuration conflict is reduced.
If the terminal device is configured by the network device to perform DRX, the terminal device is in an awake state in an eighth period, and the synchronization signal block is measured in the eighth period. If the terminal device does not transmit the uplink signal in the seventh time period (i.e., the uplink resource time period), the terminal device is in the sleep state in the seventh time period.
