Discontinuous reception method and device

[0001] This application claims priority to the Chinese patent application filed with the State Intellectual Property Office on September 23, 2022, with application number 202211166990.7 and application name “Method and Device for Discontinuous Reception”, the entire contents of which are incorporated by reference into this application. Technical Field

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

[0003] Extended reality (XR) offers a new form of human-computer interaction. However, due to the large data volumes and high latency requirements of XR services, it also presents new challenges for the development of wireless networks. Connected mode discontinuous reception (CDRX) is a widely used power-saving mechanism. However, when CDRX technology is directly applied to XR services, the power savings are limited. This is primarily due to jitter in actual XR systems. Specifically, variations in frame coding delay and network transmission time cause jitter in the time when the base station receives XR service data packets (data frames). This means that when a terminal periodically transmits XR service data frames, the actual time the base station receives the data frames does not exactly correspond to the periodic arrival time. Therefore, to prevent data loss, the on-period timer in CDRX must be extended to fully cover this jitter period. However, this reduces the power savings.

[0004] Therefore, how to ensure energy saving and power saving in scenarios with jitter is a technical problem that needs to be solved urgently.

[0005] Summary of the Invention

[0006] The present application provides a method and apparatus for discontinuous reception, which can ensure energy saving and power saving.

[0007] In a first aspect, a method for discontinuous reception is provided, which is applied to a user device, and the method includes: receiving indication information sent by a network device, the indication information being used to indicate whether data arrives in advance or is used to indicate whether data arrives late; and monitoring a physical downlink control channel according to the indication information.

[0008] In the technical solution of the present application, the physical downlink control channel is mainly monitored according to the indication information of whether the data sent by the network device arrives early or late when the indication information is received, thereby ensuring the reception of data that arrives early or late due to jitter and preventing the loss of such data. Under this premise, there is no need to extend the duration of the on-period timer in the discontinuous reception in the connected state in order to completely cover the jitter interval, thereby achieving further power saving.

[0009] In the embodiment of the present application, the data can be a data frame of the XR service, a data packet of other services, or other data that can be sent and received under the CDRX mechanism, without limitation.

[0019] In combination with the first aspect, in certain implementations of the first aspect, the fact that the second DCI does not schedule the corresponding PDSCH is indicated by using a time domain resource allocation (TDRA) field in the second DCI.

[0020] In combination with the first aspect, in certain implementations of the first aspect, at least one bit in the second DCI other than the TDRA field is used to indicate at least one parameter among the configuration parameters of CDRX, or to indicate an identifier of a parameter set of the configuration parameters of CDRX, which parameter set includes at least one configuration parameter of CDRX.

[0052] The following describes the solution of the embodiment of the present application with reference to the accompanying drawings. The discontinuous reception method provided by the present application can be applied to various wireless communication systems.

[0053] Figure 1 is a schematic diagram of an applicable network scenario of an embodiment of the present application. As shown in Figure 1, the wireless communication system in this scenario includes at least one network device 110 and at least one user equipment (UE) 120. The wireless communication system can be a long-term evolution (LTE) network, a fifth-generation (5G) network, or a future sixth-generation (6G) network, or various subsequent evolved wireless communication systems capable of carrying XR services.

[0054] In an embodiment of the present application, the network device 110 may include an access network (AN) device and a radio access network (RAN) device. The access network device, such as a base station (for example, an access point), may refer to a device in the access network that communicates with a wireless terminal device through one or more cells at an air interface as a base station, for example, an evolved base station (NodeB or eNB or e-NodeB, evolved Node B), or may also include a next generation node B (gNB) or a next generation evolved node B (ng-eNB), en-gNB (enhanced next generation node B, gNB) in a 5G system: an enhanced next generation base station; it may also include a centralized unit (CU) and a distributed unit (DU) in a cloud radio access network (Cloud RAN) system, etc., which are not listed one by one.

[0055] User equipment can also be called terminal equipment, which can be mobile phones, smart watches, tablets, laptops, XR terminals, in-vehicle terminals, etc. XR terminals can also include virtual reality (VR) terminals, augmented reality (AR) terminals, and mixed reality (MR) terminals.

[0056] To facilitate understanding of the solution of the embodiment of the present application, the jitter of the XR service is introduced below in conjunction with Figure 2. Figure 2 is a schematic diagram of the periodic transmission of data frames of the XR service of the embodiment of the present application. As shown in Figure 2, the data frames of the XR service are transmitted periodically. For example, if the transmission is periodically transmitted at a rate of 120 frames per second, the transmission period is 8.33 milliseconds, that is, the 8 transmission periods in Figure 2 can be 8.33 milliseconds. Ideally, the user device periodically sends and receives data frames, and the network device periodically sends and receives data frames at the same period. For example, when a user device periodically sends a data frame, the network device periodically receives these data frames at the same period and periodically sends them to another user device at the same period. The other user device also periodically receives these data frames at the same period. However, as mentioned above, due to the frame encoding delay of the XR service and the change in network transmission time, there is jitter at the time when the network device receives the data frame. For example, it may arrive early or late, and the length of the advance or lag can be called jitter. As shown in Figure 2, jitter1 represents the jitter of the early arrival time, and jitter2 represents the jitter of the delayed arrival time. Researchers found that jitter follows a truncated Gaussian distribution, specifically between -4 milliseconds and +4 milliseconds. This means that jitter is a random variable between -4 milliseconds and +4 milliseconds. In Figure 2, jitter2 has a range of (0, +4) and jitter1 has a range of [-4, 0], both expressed in milliseconds.

[0057] In this special case, when CDRX technology is directly applied to XR services, if the configured on-duration timer is too short, data frames will be missed due to jitter. If the on-duration timer is configured long enough to prevent missed frames, it must at least completely cover the jitter duration. In the above example, the on-duration timer needs to be at least 8 milliseconds, which will reduce the power saving effect. That is, the on-duration timer accounts for 8 milliseconds in the CDRX cycle. In addition, if the inactivity timer is too long or too short, similar problems will arise. If it is too long, it will consume power, and if it is too short, it will cause data frames to be missed.

[0058] To address the above issues, the embodiments of the present application mainly notify the user equipment in advance whether the data has arrived in advance at a certain moment before the start of the period timer, and / or, if the data has not been received at a certain moment after the start of the period timer, the network device notifies the user equipment of the delayed data arrival, so that the user equipment can use the corresponding CDRX configuration parameters to monitor the physical downlink control channel (PDCCH) according to such instructions. However, it should be understood that the method of the embodiments of the present application can be applied not only to XR services, but also to other data transmission scenarios.

[0059] FIG3 is a schematic flowchart of a discontinuous reception method according to an embodiment of the present application.

[0060] S301. The network device sends indication information to the UE.

[0061] The indication information is used to indicate whether the data arrives ahead of time or to indicate whether the data arrives behind time.

[0062] In the embodiment of the present application, the data can be a data frame of the XR service, a data packet of other services, or other data that can be sent and received under the CDRX mechanism, without limitation.

[0063] Early arrival can be understood as data having arrived when the indication information of whether early arrival is sent, while late arrival can be understood as data not having arrived (not yet arrived) when the indication information of late arrival is sent.

[0064] That is, the network device may send the above indication information to the UE, and the UE may execute step S302 after receiving the indication information.

[0065] In one implementation, the indication information includes first information, where the first information is used to indicate whether the data has arrived early. For a UE, early arrival indicates that the data has arrived when the UE receives the first information, and for a network device, early arrival indicates that the data has arrived when the network device sends the first information.

[0066] In one example, a network device may periodically send a first message to a UE. If the network device has already received data when the first message is sent, the first message is used to indicate that the data has arrived early. If the network device has not received data when the first message is sent, the first message is used to indicate that the data has not arrived early. It should be understood that "not arriving early" can include both normal arrival and delayed arrival. It should also be understood that the first message is sent regardless of whether the data has been received, and is a periodic transmission; however, it carries an indication of whether the data has been received at the time of transmission.

[0067] In another example, the network device does not send the first information to the UE periodically, but does not send the first information when the data does not arrive in advance. In this case, if the UE cannot decode the first information, it will default to believing that the data has not arrived in advance.

[0068] In one example, the first information includes first downlink control information (DCI), and a first preset bit in the first DCI is used to indicate whether the data arrives early. In other words, DCI can be used to indicate whether the data arrives early.

[0069] Optionally, the first DCI can be a UE-group common signaling DCI. That is to say, one DCI includes indications for multiple UEs. For the target UE, the field (bit segment) corresponding to the UE can be found therein, and then the indication information can be read therefrom. For example, a target UE in the first DCI corresponds to N bits (bit), and a bit of these N bits can be used as the above-mentioned first preset bit. For example, the first bit of the N bits can be used as the above-mentioned first preset bit, and the first bit includes an indication of whether the data arrives in advance. The first preset bit indicates that the data arrives in advance. For example, when the first preset bit is 0, it indicates that it does not arrive in advance, and when the first preset bit is 1, it indicates that it arrives in advance.

[0070] The structure of the first DCI can be customized or implemented by changing the structure of the existing DCI. For example, the first DCI can be a structure of DCI2_6, and each bit of DCI2_6 is redefined to meet the requirements of the first DCI.

[0071] Optionally, since only one bit is needed to indicate whether the data arrives in advance, the remaining bits can be used to further indicate the configuration parameters of CDRX, so that when the UE receives the first information, in addition to knowing whether the data arrives in advance, it can also monitor PDCCH according to the configuration parameters indicated by the first information.

[0072] In another example, at least one bit in the first DCI other than the first preset bit is used to indicate at least one parameter among the configuration parameters of CDRX, or to indicate an identifier of a parameter set of the configuration parameters of CDRX, and the parameter set includes at least one configuration parameter of CDRX.

[0073] The configuration parameters of CDRX may include at least one of an offset time (offset), an on-period timer, an inactivity timer, or a search space set group (SSSG).

[0074] For example, a parameter set of the configuration parameters of CDRX may include configuration parameters with different values, and the identifiers of the two parameter sets may be represented by index value1 and index value2, for example.

[0075] for example:

[0076] It can be seen that both data sets can include the set values ​​of several configuration parameters such as offset, on duration timer, inactivity timer and SSSG. When the first information indicates the identifier of a parameter set, the parameter set can be found and the configuration parameters in the parameter set can be used to monitor the PDCCH.

[0077] It should be noted that the first information may also implicitly indicate whether the SSSG adopts a dense SSSG or a sparse SSSG while indicating whether the data arrives in advance. That is, when the first information indicates that the data arrives in advance, it may implicitly indicate that a dense SSSG is adopted; when the first information indicates that the data does not arrive in advance, it may implicitly indicate that a sparse SSSG is adopted. In addition, the first information may also explicitly indicate whether a dense SSSG or a sparse SSSG is adopted when indicating the configuration parameters of CDRX. That is, whether the SSSG adopts sparse or dense can be indicated together with the first preset bit, or can be indicated by the bit used to indicate the CDRX configuration parameter (other bits other than the first preset bit).

[0078] In some cases, when data is sufficiently dense, a media access control (MAC) control element (CE) may be used in the previous cycle of CDRX to indicate configuration parameters for the next cycle of CDRX.

[0079] In another implementation, the indication information may include second information, where the second information is used to indicate that the data has arrived late. For the UE, the late arrival indicates that the data has not arrived (has not yet arrived) when the second information is received. For the network device, the late arrival indicates that the data has not arrived when the second information is sent.

[0080] It can be understood that the second information is sent at a certain moment after the on-duration timer has started and before it ends, or at the end time. Therefore, if the data is received at this time, there is no hysteresis. If it is not received, it is a hysteresis. The second information is sent at this time to enable the UE to respond to the hysteresis in a targeted manner. For example, a newly defined timer can be started, or a known timer with a longer duration than the on-duration timer can be directly started to ensure the reception of the delayed data. Under this premise, there is no need to extend the on-duration timer in CDRX to fully cover the jitter interval. That is, a shorter on-duration timer is used when there is no hysteresis, and a longer timer is used only when a hysteresis occurs.

[0081] It should also be understood that the second information can be sent by the network device each time the on-duration timer starts, even before data has been received. In other words, the second information is sent only when a hysteresis occurs. This approach avoids meaningless indications. Specifically, when there is no hysteresis, the CDRX mechanism itself can already meet data transmission and reception requirements, and there is no need to indicate the absence of a hysteresis. Therefore, this approach saves signaling, meaning that the number of indication messages sent is reduced, and the UE also reduces the number of times it receives and processes indication messages.

[0082] In one example, the second information includes a second DCI; the second DCI does not schedule a corresponding physical downlink shared channel (PDSCH), and the second DCI is used to indicate that data has arrived late. In this case, if the UE receives the second information, it can know two things: the data has arrived late, and the DCI does not schedule a PDSCH.

[0083] It should be noted that delayed data arrival is indicated by a special structure called the second DCI, or by the fact that the second DCI does not schedule PDSCH. This means that when the data has not yet arrived, the network device sends a second DCI. When the UE receives the second DCI and finds that it is a special DCI that does not schedule PDSCH, it knows that the data has arrived late.

[0084] Optionally, the time domain resource assignment (TDRA) indication field in the second DCI can be used to indicate that the second DCI does not schedule the corresponding PDSCH. For example, an entry corresponding to K0 can be configured through radio resource control (RRC). When the UE receives the second DCI, it finds the corresponding entry from the TDRA field in the second DCI, and then reads the value of K0 from the entry. If it is -1, it knows that the second DCI does not schedule the corresponding PDSCH, and thus knows that the data has arrived late.

[0085] In another example, at least one bit in the second DCI, other than the bit used to indicate delayed data arrival (e.g., the TDRA field described above), is used to indicate at least one CDRX configuration parameter, or to indicate an identifier of a parameter set of CDRX configuration parameters, where the parameter set includes at least one CDRX configuration parameter. In this case, if the UE receives the second DCI, it can learn three things: that the data is delayed, that this DCI does not schedule the corresponding PDSCH, and that the CDRX configuration parameter indicated by the second DCI can be parsed.

[0086] In another example, the second information includes a third DCI; the PDSCH scheduled by the third DCI is a padding PDSCH. In this case, if the UE receives the third DCI and decodes the padding PDSCH when decoding the PDSCH corresponding to the third DCI, it can be known that the data is delayed.

[0087] After receiving the indication information, the UE will execute step S302.

[0088] S302: Monitor the PDCCH according to the instruction information.

[0089] As described above, the situations indicated by the indication information may be different, so step S302 may monitor the PDCCH according to the corresponding monitoring strategy based on the different indication information.

[0090] In one implementation, when the indication information includes the first information, the first information may include two indications, the first indication being whether the data arrives in advance, and the second indication being a configuration parameter of the CDRX.

[0091] In one example, CDRX configuration parameters are also implicitly indicated by an indication of whether the data has arrived early. Upon receiving the first information, the UE monitors the PDCCH based on the CDRX configuration parameters implicitly indicated by the first information. For example, two sets of CDRX configuration parameters may be preconfigured via RRC, one corresponding to early arrival and the other corresponding to no early arrival. Upon receiving the first information, the UE learns whether the data has arrived early. If the data has arrived early, the UE monitors the PDCCH using the set of CDRX configuration parameters corresponding to the early arrival. If the data has not arrived early, the UE monitors the PDCCH using the set of CDRX configuration parameters corresponding to no early arrival.

[0092] For example, the two sets of CDRX preconfigured configuration parameters are first and second preset configuration parameters. Data not arriving early corresponds to the first preset configuration parameters, while data arriving early corresponds to the second preset configuration parameters. Therefore, when the user device determines, based on the received first information, that data has not arrived early, it can select the first preset configuration parameters for monitoring. When the user device determines, based on the received first information, that data has arrived early, it can select the second preset configuration parameters for monitoring. In this example, both the first and second preset configuration parameters can serve as the CDRX configuration parameters indicated by the first information.

[0093] For another example, CDRX can pre-configure two sets of configuration parameters: first preset configuration parameters and second preset configuration parameters, and the first preset configuration parameters are the default configuration parameters. That is, when the user device determines that the data has not arrived in advance or the first information has not been decoded based on the received first information, the default first preset configuration parameters are used for monitoring. When the user device determines that the data has arrived in advance based on the received first information, the second preset configuration parameters are selected for monitoring.

[0094] In another example, at least one bit in the first DCI other than the first preset bit is used to indicate at least one CDRX configuration parameter, or to indicate an identifier of a parameter set of CDRX configuration parameters, wherein the parameter set includes at least one CDRX configuration parameter. It can be seen that in this example, the CDRX configuration parameter is an explicit indication. When the UE receives the first information, it can determine whether the data has arrived early from the first preset bit, and can also determine the CDRX configuration parameters to be used when subsequently monitoring the PDCCH from bits other than the first preset bit.

[0095] In another implementation, step S302 may include at least one of the following operations:

[0096] According to the offset indicated by the first information, start the on duration timer in advance and monitor the PDCCH within the on duration timer; or, according to the instruction of the first information, use the dense SSSG for monitoring; or, monitor according to the on duration timer indicated by the first information; or, monitor according to the inactivity timer indicated by the first information.

[0097] That is, the first information may specifically indicate one or more configuration parameters, and the UE may monitor according to the specific parameter values ​​indicated. For example, if the UE determines, based on the first information, that the data has arrived early, it may start the on-duration timer in advance based on the offset value indicated in the first information. Furthermore, based on the early arrival, the UE may utilize a dense SSSG for monitoring, shorten the on-duration timer, and so on. These examples are not listed here.

[0098] In another implementation, the indication information may further include second information, where the second information is used to indicate that the data arrives late; when the second information is received, step S302 may include the UE monitoring the PDCCH according to the second information.

[0099] Step S302 will also perform different operations for different situations of the second information.

[0100] In an example, when the second information includes the second DCI, step S302 may include: starting a first timer to monitor the PDCCH in response to the second DCI; or monitoring the PDCCH according to the CDRX configuration parameters indicated by the second DCI.

[0101] The first timer is a new timer, which can be called a new timer, that is, a new timer with a longer duration is started. The reason is that the second DCI cannot start an inactivity timer through the natural trigger under the CDRX mechanism, so a new timer can be started. This new timer can be a newly defined timer or a reused existing timer, such as the retransmission timer drx-RetransmissionTimerDL. It should be understood that in this implementation, when the UE receives the second DCI, it knows that the data has arrived late and that it does not need to decode the PDSCH. If the second DCI does not indicate the CDRX configuration parameters, it can start a first timer, such as starting drx-RetransmissionTimerDL. If the second DCI also indicates the CDRX configuration parameters, it monitors the PDCCH according to the indicated CDRX configuration parameters. Assuming that the second DCI indicates a longer on duration timer, after receiving the second DCI, the UE knows that the data has arrived late, knows that this DCI does not need to decode the PDSCH, and knows that this DCI indicates a CDRX configuration parameter such as a longer on duration timer. The UE can start the longer on duration timer for monitoring.

[0102] In another example, when the second information includes the third DCI, step S302 may include: in response to the third DCI, starting a second timer to monitor the PDCCH. The second timer may be an inactivity timer of a default length or a preset longer inactivity timer for delayed data arrival. In this example, since the third DCI is a well-structured DCI, a timer, such as an inactivity timer, can be started through a natural trigger under the CDRX mechanism.

[0103] The method shown in Figure 3 mainly ensures the reception of data that arrives early or late due to jitter and prevents the loss of such data by monitoring the physical downlink control channel according to the indication information when receiving the indication information of whether the data sent by the network device arrives early or late, thereby preventing the loss of such data. Under this premise, there is no need to extend the duration of the on-period timer in the discontinuous reception in the connected state in order to completely cover the jitter interval, thereby achieving further power saving.

[0104] FIG4 is a schematic flow chart of another discontinuous reception method according to an embodiment of the present application. FIG4 can be regarded as a specific example of the method shown in FIG3.

[0105] S401. A network device sends first information to a UE, to indicate whether data arrives ahead of time.

[0106] Step S401 can be regarded as an example of step S301.

[0107] The network device may periodically send the first information to the UE.

[0108] The first information may be the first DCI mentioned above, for example, a UE group common DCI.

[0109] After receiving the first information, the UE executes step S402.

[0110] S402: When data arrives in advance, the UE monitors the PDCCH according to the configuration parameters of CDRX indicated by the first information.

[0111] Step S402 can be regarded as an example of step S302.

[0112] That is, the first information includes two indications, the first indicating whether the data has arrived in advance, and the second indicating the configuration parameters of CDRX.

[0113] In one implementation, the method further includes: when the data does not arrive in advance, the UE monitors the PDCCH according to the first preset configuration parameter of CDRX.

[0114] In another implementation, step S402 may include at least one of the following operations:

[0115] According to the offset indicated by the first information, start the on duration timer in advance and monitor the PDCCH within the on duration timer; or, according to the instruction of the first information, use the dense SSSG for monitoring; or, monitor according to the on duration timer indicated by the first information; or, monitor according to the inactivity timer indicated by the first information.

[0116] That is, the first information may specifically indicate one or more configuration parameters, and the UE may monitor according to the specific parameter values ​​indicated. For example, if the UE determines, based on the first information, that the data has arrived early, it may start the on-duration timer in advance based on the offset value indicated in the first information. Furthermore, based on the early arrival, the UE may utilize a dense SSSG for monitoring, shorten the on-duration timer, and so on. These examples are not listed here.

[0117] Steps S401 and S402 mainly monitor the physical downlink control channel according to the indication information when the UE receives the indication information sent by the network device whether the data has arrived ahead of time, thereby ensuring the reception of the data arriving ahead of time due to jitter and preventing the loss of such data. Under this premise, there is no need to extend the on duration timer in CDRX in order to fully cover the jitter interval, thereby achieving further power saving.

[0118] S403: The UE receives second information sent by the network device, where the second information is used to indicate delayed arrival of data.

[0119] The second information may be a second DCI or a third DCI.

[0120] Step S403 can be regarded as an example of step S301.

[0121] S404. The UE monitors the PDCCH according to the second information.

[0122] Step S404 can be regarded as an example of step S302.

[0123] Steps S403 and S404 mainly send the second information to the UE through the network device to inform it of the data lag, so that the UE can use the corresponding configuration parameters for monitoring. For example, when the data is delayed, the dense SSSG can be changed to a sparse SSSG, and a longer timer can be started, etc., which are no longer listed one by one. When there is no data lag, the default configuration parameters can continue to be used. This ensures the reception of data that arrives late due to jitter. Under this premise, there is no need to extend the on duration timer in CDRX in order to fully cover the jitter interval, thereby achieving further power saving. When steps S403-S404 are executed separately, the UE can use the corresponding CDRX configuration parameters for monitoring when the data is delayed and when the data is not delayed.

[0124] It should be understood that only steps S401-S402, only steps S403-S404, or both steps S401-S404 can be performed, all of which can achieve a further power saving effect. The power saving effect is better when both steps S401-S404 are performed.

[0125] FIG5 is a schematic diagram comparing a discontinuous reception method according to an embodiment of the present application with a conventional CDRX method. FIG5 mainly illustrates an example of processing only the case of early arrival, i.e., the case where the indication information in the method shown in FIG3 is used to indicate whether the data has arrived early (i.e., the indication information only includes the first information), and the case where the method shown in FIG4 only includes steps S401 and S402.

[0126] It should be noted that FIG5 mainly uses the example of periodic transmission of the first information for description, but does not limit the first information to be transmitted periodically. For example, the network device may not transmit the first information when it does not arrive early. In this case, if the UE cannot decode the first information, it will default to the assumption that it did not arrive early.

[0127] As shown in Figure 5 (a), the on duration timer in conventional CDRX is started periodically, and the length is fixed. In this case, in order to prevent packet loss in the XR service, the on duration timer needs to be long enough. As mentioned above, the jitter conforms to the truncated Gaussian distribution of -4 milliseconds to +4 milliseconds, so here, the on duration timer needs to be greater than or equal to 8 milliseconds. The data transmission period in the XR service is 8.33 milliseconds, that is, the on duration timer accounts for a large proportion of the CDRX period, and the power saving effect is very limited. As shown in Figure 5 (b), after the method of the embodiment of the present application is introduced, the first DCI (an example of the first information) is periodically sent, and the first information is used to inform whether the data has arrived in advance, that is, the sending period shown in Figure 5 (b) is the sending period of the first information. As shown in Figure 5(b), when the first DCI-1 is sent, the data arrives early. Therefore, the offset standard value can be reduced to offset1, which means the on-duration timer is started early and a dense SSSG is used for monitoring during the on-duration timer. Specifically, the density of the white lines in the black box during on1 is denser, and the duration of on-duration timer is shortened, meaning on1 is shorter. When the first DCI-2 is sent, the data does not arrive early. Therefore, the default offset value, offset2, can be used, and the on-duration timer is started normally. Furthermore, a sparse SSSG is used for monitoring during the on-duration timer. Specifically, the density of the white lines in the black box during on2 is the default density. When the first DCI-3 is sent, the data arrives early. Therefore, the offset standard value can be reduced to offset3, which means the on-duration timer is started early and a dense SSSG is used for monitoring during the on-duration timer. Specifically, the density of the white lines in the black box during on3 is denser, and the duration of on-duration timer is shortened, meaning on3 is shorter.

[0128] As can be seen from Figure 5, the wake-up time in CDRX is significantly shortened. This is because when data is advanced, it can wake up faster, monitor in a shorter time, and use dense SSSG for monitoring. When data is not advanced, it can continue to monitor using the default configuration parameters. This makes it more power-efficient overall compared to the conventional full coverage jitter method.

[0129] FIG6 is a schematic diagram comparing another discontinuous reception method according to an embodiment of the present application with a conventional CDRX method. FIG6 mainly illustrates an example of processing only the case of delayed arrival (i.e., the indication information includes only the second information), which is the case where the indication information in the method shown in FIG3 is used to indicate whether the data has arrived late, and the case where the method shown in FIG4 includes only steps S403 and S404.

[0130] The content shown in Figure 6 (a) can refer to the relevant description of the content shown in Figure 5 (a), which will not be repeated here. As shown in Figure 6 (b), after the method of the embodiment of the present application is introduced, a second message is sent before the on duration timer is started and the data is notified of the delayed arrival through the second message. As shown in Figure 6 (b), when the second message is sent, the data arrives delayed, and a timer can be started, which is represented by new timer in the figure. As shown in Figure 6 (b), the second message is not sent when the data is not delayed, and is only sent when the data is delayed. However, it should be understood that the new timer here may be a new timer started under the trigger of the second DCI or an existing timer. For example, the first timer may be drx-RetransmissionTimerDL, or it may be a timer started according to the CDRX configuration parameters indicated by the second DCI, or it may be a second timer started under the trigger of the third DCI. That is, as shown in Figure 6 (b), the second CDRX cycle includes a new timer, and during the timer running time, the UE monitors the PDCCH.

[0131] As shown in Figure 6, the CDRX wake-up time is significantly shortened. This is because when data is not delayed, monitoring is performed with a shorter on-duration timer. If data is delayed, monitoring can be performed with a longer timer. When data is not delayed, monitoring continues with the default configuration parameters. That is, a longer timer is used only when data is delayed, and a shorter timer is used at other times. This results in greater power savings compared to the conventional full jitter coverage method.

[0132] FIG7 is a schematic diagram comparing another discontinuous reception method according to an embodiment of the present application with a conventional CDRX method. FIG7 mainly illustrates an example of processing both early arrival and late arrival situations, i.e., the case where the indication information in the method shown in FIG3 includes the first information and the second information, and the case where the method shown in FIG4 includes steps S401-S404.

[0133] It should be noted that FIG7 mainly uses the example of periodic transmission of the first information to illustrate the present invention, but does not limit the first information to be transmitted periodically. For example, the network device may not transmit the first information when it does not arrive early. In this case, if the UE cannot decode the first information, it will assume that it has not arrived early.

[0134] FIG7 (a) can refer to the relevant descriptions of FIG5 (a) and FIG6 (a), which will not be repeated here. As shown in FIG7 (b), after introducing the method of the embodiment of the present application, the first message is periodically sent to inform whether the data has arrived early through the first message, and the second message is sent when the data is delayed. As shown in FIG7 (b), when the first message -1 is sent, the data arrives early, and the offset standard value can be reduced to offset1, that is, the on-duration timer is started early, and a dense SSSG is used for monitoring during the on-duration timer. That is, the density of the white lines in the black box during on-duration timer1 is denser, and the duration of on-duration timer is shortened, that is, on-duration timer1 is shorter. When the first message -2 is sent, the data arrives normally, and the default offset, offset2 here, is used. The on-duration timer is started normally, and a sparse SSSG is used for monitoring during the on-duration timer. That is, the density of the white lines in the black box during on-duration timer2 is the default density. When the first message -3 is sent, the data does not arrive early. The default offset, offset 3 (offset 2 and offset 3 are equal), is used, and the on-duration timer is started normally. During the on-duration timer, a second message is sent to notify the user of the delayed data arrival. As shown in Figure 7(b), when the second message is sent, the data arrives late, so a new timer is started. That is, as shown in Figure 7(b), during the last longest timer, the UE continuously monitors the PDCCH.

[0135] FIG8 is a schematic diagram of the structure of a first DCI according to an embodiment of the present application. As shown in FIG8 , the i1th bit of the first DCI is used to indicate whether the data has arrived in advance, for example, 1 corresponds to early arrival and 0 corresponds to no early arrival. That is, when the value of the i1th bit is 1, it indicates that the data has arrived in advance, and when the value of the i1th bit is 0, it indicates that the data has not arrived in advance. The i1th bit can be regarded as an example of a first preset bit. As shown in FIG8 , part or all of the N-1 bits from the i2th to the iNth bits of the first DCI can be used to indicate at least one parameter of a CDRX configuration parameter or to indicate a parameter set identifier of a CDRX configuration parameter. That is, at least one bit (herein, part or all of the N-1 bits from the i2th to the iNth bits) other than the first preset bit (herein, the i1th bit is used as an example) in the first DCI described above is used to indicate at least one configuration parameter of CDRX or to indicate a parameter set identifier of CDRX. For example, these N-1 bits can be used to indicate the offset from the first DCI to the on duration timer, such as in time slots or x milliseconds (x can be a certain value, such as 0.125, then the unit is 0.125 milliseconds). These N-1 bits can represent a unit length of 1 to 32. For example, if the value of N-1 bits is 10, it indicates 10*0.125=1.25 milliseconds. For another example, 3 bits of the N-1 bits can be used to indicate the identifier of the CDRX parameter set used. For example, if the value of 3 bits is 0, it indicates a parameter set with an index of 0. For another example, 4 bits of the N-1 bits can be used to indicate the offset, and 1 bit of the N-1 bits can be used to indicate the density identifier of the SSSG. For another example, it can be assumed that the SSSG is sparse at other times, and will only be changed to dense when the data is advanced, that is, when the first bit is 1. For another example, 3 bits out of the N-1 bits may be used to indicate the offset, and 2 bits out of the N-1 bits may be used to indicate the identifier of the SSSG to be used, where multiple SSSGs are pre-configured by RRC and distinguished by the identifier. It should be understood that the numerical values ​​in the above examples are only for facilitating understanding of the solution and are not limiting. Persons skilled in the art may select numerical values ​​as needed.
