[0049] The embodiments of the present application will be described in more detail below with reference to the accompanying drawings. It should be noted that the embodiments and features in the embodiments of the present application can be combined with each other without conflict.

[0050] In order to improve the current technical problem that it takes a long time to determine that the terminal uses a short DRX cycle, the terminal will be in a DRX activation period for a long time, which will cause the terminal to consume a lot of power and increase power consumption. This embodiment provides a communication method, such as Figure 1 As shown, the method includes:

[0051] Step 101: Receive a new DCI sent by a network device.

[0052] The execution subject of this embodiment may be a communication device or a communication equipment, which may be configured on the terminal device side, such as an electronic device or a chip, etc.

[0053] In some examples, the method shown in the present application can be executed by a terminal device, which can be called a terminal, a user equipment (UE), a mobile station (MS), a mobile terminal (MT), etc. The terminal device can also be a car with communication function, a smart car, a mobile phone, a wearable device, a tablet computer (Pad), a computer with wireless transceiver function, a virtual reality (VR) device, an augmented reality (AR) device, a wireless terminal device in industrial control, a wireless terminal device in self-driving, a wireless terminal device in remote medical surgery, a wireless terminal device in smart grid, a wireless terminal device in transportation safety, a wireless terminal device in smart city, a wireless terminal device in smart home, and a chip or chip system, etc. The embodiments of the present application do not limit the specific technology and specific device form adopted by the terminal device. In one embodiment of the present application, the network device may be a base station, a satellite or other device, which is not specifically limited in the embodiment of the present application. The network device may be an entity on the network side for transmitting or receiving signals. For example, the network 11 may be a communication satellite, an evolved NodeB (eNB), a transmission reception point (TRP), a next generation NodeB (gNB) in an NR system, a base station in other future mobile communication systems, or an access node in a wireless fidelity (WiFi) system. The embodiments of the present disclosure do not limit the specific technology and specific device form adopted by the network device 11. The network device 11 provided in the embodiment of the present disclosure may be composed of a centralized unit (CU) and a distributed unit (DU), wherein the CU may also be referred to as a control unit. The CU-DU structure may be used to split the protocol layer of the network device, such as the base station, and the functions of some protocol layers are placed in the CU for centralized control, and the functions of the remaining part or all of the protocol layers are distributed in the DU, and the DU is centrally controlled by the CU.

[0054] DRX refers to a working mode in which the terminal device turns on the receiver to enter an active state during a necessary period of time to receive downlink data, and turns off the receiver to enter a dormant state during the remaining period of time to stop receiving downlink data, thereby saving terminal power consumption.

[0055] Optionally, in the connected DRX working mode, the terminal device cannot turn off the receiver all the time, but needs to turn on the receiver periodically and start to continuously monitor the PDCCH for a period of time. This period of time is called active-time, and the DRX cycle can be divided into active-time and inactive-time according to the terminal device behavior.

[0056] Step 102: In response to the reception time of the newly transmitted DCI being within the target DRX short cycle activation time period of the network device, it is determined whether the newly transmitted DCI is a downlink DCI.

[0057] For this embodiment, after waking up, the terminal starts a DRX activation period timer (DRX-on DurationTimer) and waits for receiving a PDCCH. The running time period of the DRX-on DurationTimer is the DRX-onduration.

[0058] Optional, such as Figure 2 As shown in the figure, the DRX cycle is a periodic repetition of DRX-onduration and then enters the inactive-time period. The DRX cycle can include a DRX long cycle and a DRX short cycle. If a short-cycle is configured, the long-cycle must be a multiple of the short-cycle.

[0059] It should be noted that the active-time, that is, the time period during which the terminal monitors DCI, may include the DRX-onduration time of the DRX cycle, the time during which the terminal performs continuous reception when the DRX inactivity timer (DRX-inactivity timer) has not expired, and the time during which the terminal performs continuous reception while waiting for a retransmission opportunity.

[0060] Furthermore, the DRX-inactivity timer is the duration that the terminal waits for a successful decoding of the PDCCH from the last successful decoding of the PDCCH. If the decoding is unsuccessful, the terminal can return to sleep. The terminal should restart the DRX-inactivity timer after a single successful decoding of the initial transmission PDCCH only. Correspondingly, the retransmission timer (DRX-retransmission timer) is the timer for waiting for the retransmission to start after the initial transmission fails.

[0061] In an embodiment of the present application, after entering the activation period, the terminal can obtain the time period corresponding to the network device entering the DRX long cycle or the DRX short cycle. Since the DRX long cycle is a multiple of the DRX short cycle, if only the DRX long cycle is turned on, the activation time period obtained by the terminal and the activation time period obtained by the terminal when only the DRX short cycle is turned on will overlap, that is, the same time period can be either the activation time period corresponding to the DRX long cycle or the activation time period when the DRX short cycle is turned on.

[0062] Furthermore, the target DRX short cycle activation time period is an activation time period that can only turn on the corresponding DRX short cycle. For example, the DRX long cycle is three times the DRX short cycle. If the network device initially enters the activation time period corresponding to the DRX long cycle at 7 o'clock, 10 o'clock, and 13 o'clock, correspondingly, if the network device initially enters the activation time period corresponding to the DRX short cycle at 7 o'clock, 8 o'clock, 9 o'clock, 10 o'clock, 11 o'clock, 12 o'clock, and 13 o'clock, then the target DRX short cycle activation time period should be a time period that does not overlap with the target DRX long cycle activation time period, that is, 8 o'clock, 9 o'clock, 11 o'clock, or 12 o'clock.

[0063] It should be noted that the downlink DCI is the DCI that instructs the terminal to perform a downlink task, and correspondingly, the uplink DCI is the DCI that instructs the terminal to perform an uplink task.

[0064] Step 103: If the newly transmitted DCI is a downlink DCI, the terminal is triggered to enter a DRX short cycle.

[0065] Compared with the current existing technology, this embodiment can confirm the relationship between the time of the new transmission DCI sent by the network device and the target DRX short cycle activation time period, and then determine whether the new transmission DCI sent by the network device is a downlink DCI. If the new transmission DCI is a downlink DCI, there is no need to wait for the inactive period timer to time out to quickly trigger the terminal to enter the DRX short cycle, so that the DRX cycle of the terminal is aligned with that of the network device, avoiding DCI missed detection or false detection in the terminal. After the terminal and the base station are aligned with the DRX length cycle, the terminal can enter the DRX inactive period sleep as soon as possible without losing business stability, saving terminal power consumption and reducing power consumption.

[0066] Further, in order to illustrate the specific implementation process of the method of this embodiment, this embodiment provides the following Figure 3 The specific method shown, wherein the method includes:

[0067] Step 201: Receive a new DCI sent by a network device.

[0068] In some examples, after step 201, the method of this embodiment also includes: in response to the reception time of the newly transmitted DCI not being within the target DRX short cycle activation time period of the network device, triggering the inactive period timer to run; in response to the inactive period timer expiring, triggering the terminal to enter the DRX short cycle.

[0069] Exemplarily, if the DRX long cycle is three times the DRX short cycle, the activation time periods corresponding to the initial entry of the network device into the DRX long cycle are 7 o'clock, 10 o'clock, and 13 o'clock. Correspondingly, if the activation time periods corresponding to the initial entry of the network device into the DRX short cycle are 7 o'clock, 8 o'clock, 9 o'clock, 10 o'clock, 11 o'clock, 12 o'clock, and 13 o'clock, then the target DRX short cycle activation time period should be a time period that does not overlap with the target DRX long cycle activation time period, that is, 8 o'clock or 9 o'clock or 11 o'clock or 12 o'clock. Correspondingly, the time periods that are not within the target DRX short cycle activation time period of the network device are all remaining time periods excluding the target DRX short cycle activation time period.

[0070] In the embodiment of the present application, the operation of the inactive period timer may be in the form of starting a countdown. Accordingly, after the countdown ends, it indicates that the inactive period ends and the active period begins.

[0071] Optionally, before step 201, the method of this embodiment further includes: determining DRX configuration information sent by the network device.

[0072] The DRX configuration information includes the configuration information of the DRX short cycle.

[0073] It should be noted that, when the terminal is configured with a DRX short cycle and a DRX long cycle, after the inactive period timer times out, the terminal will enter the DRX short cycle.

[0074] In some examples, such as Figure 4 As shown, after the initial configuration of DRX, in order to clarify whether the DRX cycle to be used initially is a DRX long cycle or a DRX short cycle, it is necessary to wait for the Scheduling Request (SR) to be allowed by the network device before starting the corresponding DRX timer to enter the DRX cycle.

[0075] It should be noted that if Figure 5 As shown, during the DRX-onduration of the DRX long cycle, the terminal cannot monitor the PDCCH for a period of time, and this period includes the DRX-onduration of the DRX long cycle. Since it is impossible to determine whether the base station has sent DCI during the DRX-onduration, the terminal cannot confirm whether the base station uses the DRX long cycle or the DRX short cycle, and needs to wait for SR scheduling before starting the DRX corresponding timer to enter the long and short cycles.

[0076] Step 202: In response to the reception time of the newly transmitted DCI being within the target DRX short cycle activation time period of the network device, it is determined whether the newly transmitted DCI is a downlink DCI.

[0077] According to the judgment result, the process shown in the following steps 203a to 204a can be executed, or the process shown in step 203b can be executed.

[0078] Step 203a: If the newly transmitted DCI is uplink DCI, determine the time interval between the first moment when the network device sends the DRX configuration information and the second moment when the terminal receives the newly transmitted DCI.

[0079] In the embodiment of the present application, the first moment is the moment corresponding to when the network device sends down the DRX configuration information, and the second moment is the moment corresponding to when the terminal receives the newly transmitted DCI.

[0080] Exemplarily, if the first time is 7 o'clock and the second time is 8 o'clock, the time interval is 1 hour.

[0081] Step 204a: based on the relationship between the time interval and the SR cycle, trigger the terminal to enter the DRX short cycle.

[0082] Optionally, step 204a may specifically include: if the time interval is smaller than the SR cycle, triggering the terminal to enter a DRX short cycle.

[0083] In the embodiment of the present application, step 204a specifically also includes: if the time interval is greater than the SR cycle, triggering the inactive period timer to run; in response to the inactive period timer timing out, triggering the terminal to enter the DRX short cycle.

[0084] Exemplarily, based on step 204a, if the SR cycle is half an hour, which is less than the time interval determined in step 203a, the inactive period timer is triggered to run; in response to the expiration of the inactive period timer, it is determined that the terminal enters the DRX short cycle or the DRX long cycle; accordingly, if the SR cycle is two hours, the terminal is triggered to enter the DRX short cycle.

[0085] In step 203b, which is parallel to step 203a, if the newly transmitted DCI is a downlink DCI, the terminal is triggered to enter a DRX short cycle.

[0086] In an embodiment of the present application, after step 203b, the method of this embodiment also includes: determining whether the time information of the terminal entering the DRX short cycle meets the start condition of the activation period timer; if the start condition is met, starting the activation period timer to detect the retransmitted DCI before the short cycle timer times out.

[0087] In some examples, the activation period timer is started under the following conditions:

[0088] [(SFN*10)+subframeNumber]modulo(shortDRX-Cycle)=

[0089] (DRXStartOffset)modulo(shortDRX-Cycle)

[0090] In the start condition, modulo indicates modulus, subframeNumber indicates the number of subframes, SFN indicates system frame number (System Frame Number, SFN), and shortDRX-Cycle indicates a DRX short cycle.

[0091] Optional, such as Figure 6 The figure shows a confirmation flow chart of the terminal confirming that the initial DRX cycle configured by the base station is a DRX long cycle or a DRX short cycle after the initial configuration of DRX. From the above process, it can be seen that only after the DRX-Inactivity timer runs or the media access control layer (Media Access Control, MAC) control element (Control Element, CE) of the DRX command word (command) is received, it can be determined whether the DRX is running in the DRX long cycle or the DRX short cycle.

[0092] For example, when the DRX-onduration of the long DRX cycle cannot monitor the PDCCH to detect the DCI due to reasons such as the RF channel being occupied, it is also necessary to re-acquire the process of synchronizing with the DRX cycle of the network device.

[0093] The 3GPP protocol does not clearly specify whether the initial DRX cycle of the base station and the terminal is a long DRX cycle or a short DRX cycle. Figure 7 As shown, the terminal can prioritize the short DRX cycle by default. Since the long DRX cycle is a multiple of the short cycle, the moment when the DRX-onduration of the two DRX cycles intersects can be aligned with the network.

[0094] As an alternative, Figure 8 As shown, DRX is kept activated until the DCI is received and the DRX-inactivity timer is started, and then the DRX-ShortCycle timer is further started to synchronize the long and short cycles.

[0095] Both of the above methods cannot align the cycle with the base station for a long time, resulting in idling and inability to sleep to save power.

[0096] Compared with the current existing technology, this embodiment can determine whether the newly transmitted DCI sent by the network device is a downlink DCI by confirming the relationship between the time of the newly transmitted DCI sent by the network device and the target DRX short cycle activation time period. If the newly transmitted DCI is a downlink DCI, it is not necessary to wait for the inactive period timer to time out to quickly trigger the terminal to enter the DRX short cycle. The terminal can also effectively identify the scheduling behavior of the DRX DRX-onduration time network device, and relatively accurately determine whether the current DRX is working in a DRX long cycle or a DRX short cycle terminal, which can reduce the time when the DRX-onduration start time is inconsistent with the base station, align the DRX cycle of the network device and the terminal as soon as possible, and avoid DCI missed detection or false detection in the terminal. After the terminal and the base station align the DRX length cycle, the terminal can enter the DRX inactive period sleep as soon as possible without losing business stability, saving terminal power consumption and reducing power consumption.

[0097] In order to illustrate the specific implementation process of this embodiment, the following specific application examples are given: Fig. 9 As shown, but not limited to:

[0098] After the network device sends the DRX configuration, the terminal determines the DRX length cycle configuration; if the base station is only configured with a DRX long cycle or only configured with a DRX short cycle, the DRX cycles of the terminal and the base station are always aligned without subsequent alignment; if both a DRX short cycle and a DRX long cycle are configured, the terminal continuously detects DCI.

[0099] When the terminal receives a valid new DCI sent by the network device, it determines whether the reception time of the DCI falls within the DRX-onduration of the DRX short cycle; if it does not fall within the DRX-onduration, the DRX-inactivity timer is started, and when the DRX-inactivity timer times out, the DRX-ShortCycleTimer is started to enter the DRX short cycle; if the reception time of the DCI falls within the DRX-onduration, it is determined that if the first received DCI is a downlink DCI, the DRX short cycle is immediately entered, and the short DRX cycle is used to calculate the most recent DRX-onduration start time, and the DRX activation period and inactivation period are comprehensively judged according to the operating status of the DRX-onduration timer, the DRX-inactivity timer, the uplink retransmission timer (DRX-RetransmissionTimerUL), and the downlink retransmission timer (DRX-RetransmissionTimerDL), to determine whether the terminal detects the retransmitted DCI;

[0100] If the DCI received for the second time is an uplink DCI, the time interval T from the issuance of the DRX configuration to the detection of the first valid DCI is determined. If T is completely contained in an SR cycle and the terminal has not reported an SR in this SR cycle, the DRX short cycle is immediately entered, and the short DRX cycle is used to calculate the most recent DRX-onduration start time. The DRX activation period and inactivation period are comprehensively determined according to the operating status of the DRX DRX-onduration timer, DRX-inactivity timer, DRX-RetransmissionTimerUL, and DRX-RetransmissionTimerDL to determine whether the terminal detects the retransmitted DCI; if T is not completely contained in an SR cycle, the DRX-inactivity timer is started. When the DRX-inactivitytimer times out, the DRX-ShortCycleTimer is started to enter the DRX short cycle.

[0101] Compared with the current existing technology, this embodiment can determine whether the newly transmitted DCI sent by the network device is a downlink DCI by confirming the relationship between the time of the newly transmitted DCI sent by the network device and the target DRX short cycle activation time period. If the newly transmitted DCI is a downlink DCI, it is not necessary to wait for the inactive period timer to time out to quickly trigger the terminal to enter the DRX short cycle. The terminal can also effectively identify the scheduling behavior of the DRX DRX-onduration time network device, and relatively accurately determine whether the current DRX is working in a DRX long cycle or a DRX short cycle terminal, which can reduce the time when the DRX-onduration start time is inconsistent with the base station, align the DRX cycle of the network device and the terminal as soon as possible, and avoid DCI missed detection or false detection in the terminal. After the terminal and the base station align the DRX length cycle, the terminal can enter the DRX inactive period sleep as soon as possible without losing business stability, saving terminal power consumption and reducing power consumption.

[0102] Further, as Figure 1 and Figure 3 The specific implementation of the method shown in this embodiment provides a communication device, such as Fig.10 As shown, the device includes: a receiving module 31, a judging module 32, and a triggering module 33.

[0103] The receiving module 31 is configured to receive new downlink control information DCI sent by the network device;

[0104] The judging module 32 is configured to judge whether the newly transmitted DCI is a downlink DCI in response to the reception time of the newly transmitted DCI being within the target DRX short cycle activation time period of the network device;
