Description

Information processing methods and devices, communication equipment and storage media

Technical field

The present disclosure relates to the field of wireless communication technology but is not limited to the field of wireless communication technology, and in particular, to an information processing method and device, communication equipment and storage medium.

Background technique

In the fifth generation mobile communication ( ^5th Generation, 5G) communication system, in order to save the power consumption of user equipment (User Equipment, UE), a discontinuous reception (Discontinuous Reception, DRX) mechanism is introduced.

That is, when the UE is in the connected state, it does not need to continuously monitor the control channel (for example, Physical Downlink Control Channel, PDCCH) of the base station (for example, gNB), but intermittently monitors the control channel.

The wake-up period (On Duration) is the time period during which the UE monitors the control channel. During the wake-up period, the radio frequency channel within the UE is open and the control channel is continuously monitored.

At other times than the wake-up period (On Duration), the UE is in a power saving state and the radio frequency channel in the UE is closed.

The wake-up period (On Duration) occurs according to the DRX cycle. The DRX cycle is configured by the base station (gNB).

While achieving UE power saving, in order to reduce the excessive transmission delay between gNB and UE, the DRX cycle can be divided into at least DRX long cycle (Long Cycle) and DRX short cycle (Short Cycle). DRX long cycle can be referred to as long cycle; DRX short cycle can be referred to as short cycle. The duration of long cycles is longer than the duration of short cycles.

In the example shown in Figure 1, 1 long period equals 3 short periods. It can be seen that the wake-up period (On Duration) occurs in a short period and appears more frequently in the time domain.

Please refer to FIG. 2 , which shows a schematic structural diagram of a wireless communication system provided by an embodiment of the present disclosure. As shown in Figure 1, the wireless communication system is a communication system based on cellular mobile communication technology. The wireless communication system may include: several UEs 11 and several access devices 12.

Wherein, UE 11 may be a device that provides voice and/or data connectivity to users. The UE 11 can communicate with one or more core networks via a Radio Access Network (RAN). The UE 11 can be an Internet of Things UE, such as a sensor device, a mobile phone (or a "cellular" phone) and a device with The computer of the IoT UE may, for example, be a fixed, portable, pocket-sized, handheld, computer-built-in or vehicle-mounted device. For example, station (STA), subscriber unit (subscriber unit), subscriber station, mobile station (mobile station), mobile station (mobile), remote station (remote station), access point, remote UE ( remote terminal), access UE (access terminal), user terminal (user terminal), user agent (user agent), user equipment (user device), or user UE (user equipment, UE). Alternatively, UE 11 can also be a device for an unmanned aerial vehicle. Alternatively, the UE 11 may also be a vehicle-mounted device, for example, it may be a driving computer with a wireless communication function, or a wireless communication device connected to an external driving computer. Alternatively, the UE 11 can also be a roadside device, for example, it can be a street light, a signal light or other roadside equipment with wireless communication functions.

The access device 12 may be a network-side device in the wireless communication system. Among them, the wireless communication system can be the 4th generation mobile communication technology (the 4th generation mobile communication, 4G) system, also known as the Long Term Evolution (LTE) system; or the wireless communication system can also be a 5G system, Also called new radio (NR) system or 5G NR system. Alternatively, the wireless communication system may also be a next-generation system of the 5G system. Among them, the access network in the 5G system can be called NG-RAN (New Generation-Radio Access Network). Or, MTC system.

The access device 12 may be an evolved access device (eNB) used in the 4G system. Alternatively, the access device 12 may also be an access device (gNB) using a centralized distributed architecture in the 5G system. When the access device 12 adopts a centralized distributed architecture, it usually includes a centralized unit (central unit, CU) and at least two distributed units (distributed unit, DU). The centralized unit is equipped with a protocol stack including the Packet Data Convergence Protocol (PDCP) layer, the Radio Link Control protocol (Radio Link Control, RLC) layer, and the Media Access Control (Media Access Control, MAC) layer; distributed The unit is provided with a physical (Physical, PHY) layer protocol stack, and the embodiment of the present disclosure does not limit the specific implementation of the access device 12.

A wireless connection can be established between the access device 12 and the UE 11 through the wireless air interface. In different implementations, the wireless air interface is a wireless air interface based on the fourth generation mobile communication network technology (4G) standard; or the wireless air interface is a wireless air interface based on the fifth generation mobile communication network technology (5G) standard, such as The wireless air interface is a new air interface; alternatively, the wireless air interface may also be a wireless air interface based on the next generation mobile communication network technology standard of 5G.

As shown in Figure 3, an embodiment of the present disclosure provides an information processing method, which is executed by a UE. The method includes:

S1110: Determine the time domain starting position of the wake-up period of the current DRX cycle according to the index of the current DRX cycle.

The UE may be any communication device. For example, the communication device may be a fixed device and/or a mobile device. The mobile devices include but are not limited to: mobile phones, tablet computers, wearable devices, vehicle-mounted devices, smart home devices or smart office devices, etc. The fixed equipment includes but is not limited to: fixed smart home equipment and/or office equipment.

In some embodiments, the index of the current DRX cycle may be related to the DRX cycle experienced after the UE enters DRX this time. Normally, the larger the count value of the current DRX cycle is, the larger the index of the current DRX cycle is. In the embodiment of the present disclosure, according to the different indexes of the current DRX cycle, it means that the UE is experiencing different DRX cycles. Considering the uncertainty of the service occurrence timing of the service (for example, the extended display (eXtended Reality, XR) service), through This method re-determines the time domain starting position of the DRX cycle (which can also be called the time domain starting position), thus meeting the communication requirements of different types of services.

As shown in Figure 4 and Figure 5, if the UE's service data is periodic service, but due to network jitter, it may reach the UE at different time points in different cycles. This network jitter may accumulate the number of cycles. Too much, causing the service data originally located in the wake-up period of the DRX cycle to move outside the DRX cycle wake-up period of the UE.

For example, assuming that the service data reaches 60 frames per second (Frame Per Second, FPS), that is, the cycle is 16.67ms, the jitter delay can be between -4 and 4ms. Referring to Figure 4, if the UE subscribes to a periodic service, the time interval between two data arrivals can be 1/FPS. The time interval between data packet Y and data packet Y+1 in Figure 4 can be 1/FPS. As shown in Figure 5, a schematic diagram of the offset of service data relative to the DRX cycle wake-up period.

If the starting position of the time domain is different, the moment when the current DRX cycle enters the wake-up period (onduration) is different, and the distribution position of the entire wake-up period in the time domain is different, then the wake-up periods of different DRX cycles are aperiodic in the time domain. appears or occurs at non-fixed intervals, so the UE will activate aperiodically. The activated UE can monitor the downlink channel and/or send data on the uplink channel, thereby realizing timely transmission of aperiodic services or burst services.

In some embodiments, the UE may be a UE configured with low latency tolerance such as XR service and having traffic burstiness. UEs that are not configured with low-tolerance delays such as XR services and/or have bursty traffic can continue to determine the time domain starting position of the wake-up period of the current DRX cycle according to relevant technical solutions. For example, the time domain starting position of the wake-up period of each DRX cycle is determined according to the start adjustment value. In this way, compatibility of the starting time domain positions of the wake-up periods of UEs configured or subscribed to different services is achieved.

In an embodiment of the present disclosure, determining the time domain starting position of the wake-up period of the current DRX cycle based on the index of the current DRX cycle may include: based on the remainder modulo the index of the DRX cycle and a preset value, Determine the time domain starting position of the current DRX cycle wake-up period. The preset value may be the number of fallback cycles of the starting position of the time domain of the wake-up period. For example, if the default value is 10, it means that one round of adjustment of the time domain starting position of the wake-up period involves 10 values.

As shown in Figure 6, an embodiment of the present disclosure provides an information processing method, which is executed by a UE. The method includes:

S1210: Count the number of DRX cycles to obtain the index of the current DRX cycle.

S1220: Determine the time domain starting position of the wake-up period of the current DRX cycle according to the index of the current DRX cycle.

After the UE enters the DRX mechanism, the counting of DRX cycles experienced by the UE starts.

The DRX cycle may be a DRX long cycle and/or a DRX short cycle.

Normally, the duration of the DRX long period is longer than the duration of the DRX short period.

For example, the alternative duration of the DRX long period may include at least one of the following: 10ms, 20ms, 32ms, 40ms, 60ms, 64ms, 70ms, 80ms, 128ms, 160ms, 256ms, 320ms.

As another example, the alternative duration of the DRX short period may include at least one of the following: 2ms, 3ms, 4ms, 5ms, 6ms, 7ms, 8ms, 10ms, 14ms, 16ms, 20ms, 30ms, 32ms, 35ms, 40ms, 64ms , 80ms, 128ms, 160ms, 256ms, 320ms, 512ms, 640ms.

In one embodiment, DRX long periods and DRX short periods may not be distinguished, and DRX periods may be counted uniformly.

In another embodiment, DRX long periods and DRX short periods can be distinguished and counted separately.

Using the above two embodiments to count DRX cycles, the obtained count values of DRX cycles are different, so the index of the current DRX cycle may be different.

For example, the count value of the current DRX cycle can be directly used as the index of the current DRX cycle.

In some embodiments, if both the DRX long cycle and the DRX short cycle are configured for the UE, after the UE enters the DRX mechanism, the UE can switch between the DRX long cycle and the DRX short cycle. For example, after starting the DRX short cycle, the UE enters the DRX long cycle after the DRX short cycle timer (drx-ShortCycleTimer) times out.

In other embodiments, if only the DRX long period is configured for the UE, after the UE enters the DRX mechanism, the UE counts the DRX long period. If only the DRX short cycle is configured for the UE, after the UE enters the DRX mechanism, the UE counts the DRX short cycle.

In short, there are many indexing methods for determining the DRX cycle, and the specific implementation is not limited to the above example.

In some embodiments, the index is obtained by counting the number of non-continuous reception DRX cycles, including at least one of the following:

Continuously count the number of DRX long periods of the UE and use the count value as the index of the current DRX long period;

After the DRX short cycle of the UE is started and before the DRX short cycle timer corresponding to the DRX short cycle is restarted, count the DRX short cycle and use the counted value as the index of the current short DRX cycle;

If the DRX cycle is a DRX short cycle, after switching from the DRX long cycle to the DRX short cycle, the DRX short cycle is continued to be counted according to the count value of the DRX long cycle, and the continued counting value is As the index of the DRX short period.

In the embodiment of the present disclosure, if the DRX long cycle is currently executed, the DRX long cycle is directly counted, and then the index of the current DRX long cycle is obtained based on the count value corresponding to the current DRX long cycle.

In the embodiment of the present disclosure, after the UE starts the DRX short cycle and before triggering the exit from the DRX short cycle and entering the DRX long cycle, the DRX short cycle is continuously counted, and the counted value is used as the index of the current short DRX cycle. .

In some embodiments, if the UE enters the DRX short period, the count value of the DRX long period can be used, and the count value of the last DRX long period before entering the DRX short period can be continued to count, and the count value of the continued counting can be used as the DRX Short period index.

In some embodiments, determining the time domain starting position of the wake-up period of the current DRX cycle based on the index of the current non-continuous reception DRX cycle includes:

According to the index and the first offset value, the time domain starting position of the wake-up period in the current DRX cycle is determined.

Exemplarily, the time domain starting position of the current DRX cycle wake-up period is determined according to the product of the index and the first offset value.

In another example, the time domain starting position of the current DRX cycle wake-up period is determined according to the sum of the index and the first offset value.

As another example, the time domain starting position of the current DRX cycle wake-up period is determined according to the remainder of the quotient of the index and the first offset value.

The first offset value can be determined in many ways. The first offset value is different from the starting adjustment value.

In some embodiments, the first offset values for the DRX long period and the DRX short period may be the same or different.

In short, in the embodiment of the present disclosure, the adjustment amount is determined by combining the index and the first offset value. The adjustment amount may be an adjustment amount of the time domain starting position of the wake-up period of the current DRX cycle.

In some embodiments, the method further includes at least one of the following:

Determine the first offset value according to the agreement;

Receive network signaling carrying the first offset value.

For example, the first offset value may be pre-agreed in the communication protocol, so that the UE may determine the first offset value through protocol query.

In other embodiments, network signaling sent by a network device may be received, and the first offset value may be extracted from the network signaling. The network signaling may include but is not limited to: RRC signaling, MAC CE signaling, and/or DCI, etc.

In this way, the UE can receive the network signaling before entering the sleep period of the DRX cycle, thereby extracting the first offset value from the network signaling.

S1310: Count the number of DRX cycles to obtain the index of the current DRX cycle.

S1320: Determine the adjustment amount according to the index and the first offset value;

S1330: Determine the time domain starting position of the wake-up period in the current DRX cycle based on the adjustment amount and the starting adjustment value of the time domain starting position.

Exemplarily, the adjustment amount is determined according to the product of the index and the first offset value. After determining the adjustment amount of the current DRX cycle, combined with the starting adjustment value for the DRX cycle, the time domain starting position of the current DRX cycle is determined.

Assume that the adjustment amount is T1 and the starting adjustment value is T2. If the wake-up period of the current DRX cycle is delayed by T1+T2 from the starting point of the wake-up period of the previous DRX cycle.

In other embodiments, the adjustment amount may also be sent by the network on the network side. For example, the base station can obtain the adjustment amount of the current DRX cycle in the previous DRX cycle of the UE, and send the adjustment amount to the UE through network signaling during the wake-up period of the previous DRX cycle. In this way, the UE can determine the adjustment amount of the current DRX cycle by receiving network signaling.

In some embodiments, before the UE starts the DRX mechanism, the adjustment amount of each DRX cycle is sent to the UE at once through network signaling, and the UE subsequently queries each DRX based on the adjustment amount carried in the pre-received network signaling. The adjustment amount of the cycle, and determine the time domain starting position of each DRX cycle wake-up period.

In short, there are many ways to determine the adjustment amount, which are not limited to the above examples.

For example, in some embodiments, the adjustment amount is determined based solely on the index and the first offset value.

For another example, in other embodiments, other parameters other than the index and the first offset value are also introduced to determine the adjustment amount. Illustratively, the parameters other than the index and the first offset value include but are not limited to offset factors.

In some embodiments, the method further includes:

Determine the offset factor;

Determining the adjustment amount according to the index and the first offset value includes:

The adjustment amount is determined based on the index, the first offset value and the offset factor.

The offset factor may be agreed upon by a protocol or configured by the network side. If the offset factor is configured by the network side, the UE can determine the offset factor by receiving network signaling.

The offset factor may include a weighting factor or a bias factor. If the offset factor is a weighting factor, the index and/or the first offset value will be multiplied by the offset factor to obtain the adjustment amount.

If the offset factor is an offset factor, the index and/or the first offset value will be added to the offset factor to obtain the adjustment amount.

For example, the offset factor is a weighting factor and has a value of k. Assume that the first offset value is offset1 and the index is i, then the adjustment amount can be i*offset1*k.

Of course, the above are just examples for determining the adjustment amount, and the specific implementation is not limited to the above examples.

In some embodiments, the adjustment amount may be: floor((Index modulo M)/N)*offset; floor means rounding down. Index is the index of the current DRX cycle; M is the number of fallback cycles; N is the number of DRX cycles involved in one round of adjustment of the wake-up period.

In some embodiments, the method further includes:

When switching from a DRX long period to a DRX short period, the adjustment amount corresponding to the DRX short period after switching is equal to the adjustment amount corresponding to the DRX long period before switching;

or,

When switching from a DRX long period to a DRX short period, determine the adjustment amount of the first DRX short period after the switch based on the adjustment amount corresponding to the DRX long period before switching and the second offset value;

or,

When switching from a DRX long period to a DRX short period, the adjustment amount of the first DRX short period after switching is determined based on the network signaling received before switching to the DRX short period.

In one embodiment, if the UE exits from the DRX long cycle and enters the DRX short cycle, the DRX short cycle after the handover can inherit the adjustment amount of the DRX long cycle before the handover. Equivalently in this embodiment, the first period that enters the DRX short period follows the adjustment amount corresponding to the last DRX long period before entering the DRX short period.

In another embodiment, when entering from the DRX long period to the DRX short period, on the one hand, the adjustment value of the DRX long period is inherited, but not directly, but based on the second offset value corresponding to the DRX short period. Further adjustments are made to the adjustment values inherited from the DRX long cycle. For example, the adjustment value inherited from the DRX long period is deta1, and assuming that the second offset value is offset2, the adjustment amount of the first DRX short period that the UE enters after exiting the DRX long period may be deta1+offset2.

In some embodiments, if the current DRX cycle is the xth DRX short cycle after the UE exits the DRX long cycle, the adjustment amount corresponding to the xth DRX short cycle may be: deta1+x*offset2/S; S may be Any preset positive integer.

In some embodiments, the UE exits the DRX long cycle and enters the DRX short cycle, which can be triggered by a short cycle timer or indicated by network signaling. For example, the UE receives an indication to enter a DRX short period.

In some embodiments, network equipment such as base stations can also issue the adjustment value of the first DRX short period after entering the DRX short period. In this way, the adjustment value corresponding to the subsequent DRX short period can be adjusted in the first DRX short period. Calculated based on the adjustment value, or calculated directly based on the index of the DRX short period and the first offset value corresponding to the DRX short period.

If the adjustment value of the first DRX short cycle after switching is determined based on the adjustment value corresponding to the last DRX long cycle that enters the DRX short cycle, the continuity of the time domain starting position adjustment of the DRX cycle wake-up period under the DRX mechanism can be achieved.

The network signaling carrying the adjustment value of the first DRX short cycle after the UE enters the DRX short cycle may be signaling instructing the UE to exit the DRX long cycle and enter the DRX short cycle.

The above provides several conversion relationships of adjustment values when switching between DRX long period and DRX short period. The specific implementation is not limited to the above examples.

In some embodiments, the method further includes:

Send assistance information to the network device; wherein the assistance information includes: the first offset value for the DRX long cycle expected by the UE, and/or the first offset value for the DRX short cycle expected by the UE .

In some embodiments, the method further includes:

Send assistance information to the network device; wherein the assistance information includes: an adjustment amount for the DRX long cycle expected by the UE, and/or an adjustment amount for the DRX short cycle expected by the UE.

In some embodiments, the UE may determine a recommended value of the first offset value that is suitable for the UE according to its own type, the services it subscribes to, the sending and receiving rules of its own service data, etc.

In one embodiment, the auxiliary information carries a recommended value of the first offset value. The recommended value can be for both the DRX long period and the DRX short period, or for the DRX long period alone, or for the DRX short period alone. . In another embodiment, the auxiliary information may be written to two recommended values of the first offset value, one of which is directed to the DRX short period of the UE, and the other recommended value is directed to the DRX long period of the UE.

For example, if the UE itself does not subscribe to aperiodic and low-delay tolerance services, it is not necessary to carry the recommended value of the first offset value in the auxiliary information. If the network device on the network side does not receive the auxiliary information, it may be considered that there is no need to set the first offset value for the UE or determine the time domain starting position of the wake-up period of the DRX cycle based on the first offset value and the index of the DRX cycle. Adjustment.

As an embodiment, only the time-domain starting position of the DRX short-cycle wake-up period can be adjusted based on the protocol agreement, but the time-domain starting position of the DRX long-cycle wake-up period is not adjusted. For example, if the service data of the XR service arrives, it will trigger the terminal to enter the DRX short period. At this time, it is only necessary to consider adjusting the time domain starting position of the onduration in the DRX short period to match the XR service. business data reached. For the long DRX cycle, there is no need to adjust the time domain starting position of the wake-up period, and no additional adjustment is required.

In some embodiments, the UE has multiple DRX packets, and the first offset values corresponding to different DRX packets are the same.

For example, the UE has multiple radio frequency groups, and different radio frequency groups may belong to the same or different DRX groups. If a UE has multiple DRX packets, the multiple DRX packets can share the same first offset value. In this way, the UE maintains a first offset value for the multiple DRX packets, thereby reducing the first offset value maintained by the UE. number. If the UE does not receive the first offset value sent by the network device or does not send the recommended value of the first offset value to the network device, the time domain starting position of each DRX cycle can be determined according to the starting adjustment value.

In some embodiments, the UE has multiple DRX packets, and the adjustment amounts corresponding to different DRX packets are the same.

For example, the UE has multiple radio frequency groups, and different radio frequency groups may belong to the same or different DRX groups. If a UE has multiple DRX groups, the multiple DRX groups can share the same adjustment amount. In this way, the UE maintains one adjustment amount for multiple DRX groups, thereby reducing the number of adjustment amounts maintained by the UE.

If the UE does not receive the adjustment amount sent by the network device or does not send the recommended value of the adjustment amount to the network device, the time domain starting position of each DRX cycle can be determined according to the starting adjustment value.

In some embodiments, the method further includes:

When it is determined according to the network configuration that the network device configures the power-saving signal downlink control information DCP for the UE, the monitoring time of the DCP is determined based on the determined time domain starting position of the wake-up signal within the DRX long period.

In this embodiment of the present disclosure, if the network side device configures DCP for the UE, since the time domain starting position of the DRX periodic wake-up period changes, the monitoring time of the DCP is adjusted following the adjustment of the time domain starting position of the DRX long period wake-up period. , In this way, it is reduced that it takes a long time for the UE to enter the wake-up period before starting to monitor the DCP or to enter the wake-up period before monitoring the DCP.

The DCP can be used to indicate whether the UE needs to wake up in the wake-up period corresponding to the DRX long period corresponding to the DCP, thereby reducing the DCP monitoring disorder caused by the lack of synchronization adjustment of the DCP monitoring time and the time domain starting position of the DRX long-period wake-up period. and unnecessary waste of power consumption.

As shown in Figure 7, an embodiment of the present disclosure provides an information processing method, which is executed by a base station. The method includes:

S2110: Determine the time domain starting position of the wake-up period of the current DRX cycle of the UE according to the index of the current DRX cycle of the UE.

The method can be executed by a base station, which is a type of network device on the network side accessing the network.

According to the index of the current DRX cycle, the time domain starting position of the UE's current DRX cycle wake-up period is determined. In this way, if it is subsequently necessary to send downlink instructions and/or downlink services to the UE, the time domain start position of the UE in each DRX cycle wake-up period can be determined. The time domain starting position determines the wake-up period of the UE under the DRX mechanism, and sends downlink instructions and/or downlink services to the UE during the wake-up period.

In some embodiments, the method further includes:

The number of discontinuous reception DRX cycles of the UE is counted to obtain the index of the current DRX cycle.

After the UE switches from the DRX long period to the DRX short period, the DRX short period is continued to be counted according to the count value of the DRX long period, and the value of the continued counting is used as the current DRX short period. index of.

The DRX short cycle timer here can be: DRX short cycle timer (drx-ShortCycleTimer).

For example, the current DRX cycle can directly use the count value as the index of the current DRX cycle.

In some embodiments, determining the time domain starting position of the DRX cycle wake-up period according to the index of the UE's current non-continuous reception DRX cycle includes:

According to the index and the first offset value, the time domain starting position of the wake-up period in the current DRX cycle of the UE is determined.

In this embodiment of the present disclosure, the time domain starting position of the current DRX cycle wake-up period of the UE is determined based on the index and the first offset value, so that the time domain starting position of different DRX cycles can be adjusted through the first offset value. The offset of the position relative to the starting adjustment value.

In some embodiments, the method further includes:

Determine the first offset value according to the agreement;

Send network signaling carrying the first offset value.

In some embodiments, the first offset value may be pre-agreed in the communication protocol, so that the UE may determine the first offset value through protocol query.

In some embodiments, determining the time domain starting position of the wake-up period in the current DRX cycle of the UE according to the index and the first offset value includes:

Determine an adjustment amount according to the index and the first offset value;

According to the adjustment amount and the starting adjustment value of the time domain starting position, the time domain starting position of the wake-up period in the current DRX cycle of the UE is determined.

Assume that the adjustment amount is T1 and the starting adjustment value is T2. If the wake-up period of the current DRX cycle is delayed backward by T1+T2 from the end of the previous DRX cycle.

For another example, in other embodiments, other parameters other than the index and the first offset value are also introduced to determine the adjustment amount. Illustratively, the parameters other than the index and the first offset value include but are not limited to offset factors. In some embodiments, the method further includes:

In some embodiments, the method further includes:

Receive assistance information sent by the UE; wherein the assistance information includes: a first offset value for the DRX long cycle expected by the UE, and/or a first offset value for the DRX short cycle expected by the UE. Shift value.

In some embodiments, the UE may determine a recommended value of the first offset value that is suitable for the UE according to its own type, the services it subscribes to, the sending and receiving rules of its own service data, etc. The suggested value may be sent by the UE to the base station through various signaling, so that the base station will receive the suggested value of the first offset value. In the embodiment of the present disclosure, the suggested value of the first offset value is carried in the auxiliary information.

In one embodiment, the auxiliary information carries a recommended value of the first offset value. The recommended value can be for both the DRX long period and the DRX short period, or for the DRX long period alone, or for the DRX short period alone. .

In another embodiment, the auxiliary information may be written to two recommended values of the first offset value, one of which is directed to the DRX short period of the UE, and the other recommended value is directed to the DRX long period of the UE.

For example, if the UE has multiple DRX packets, the first offset values corresponding to different DRX packets are the same.

The base station knows each DRX packet of the UE. If multiple DRX packets of a UE (for example, two DRX packets) share the same first offset value, both the base station and the UE only need to maintain one first recommended value of the UE.

In some embodiments, the method further includes:

When it is determined according to the network configuration that the network device configures the power saving signal downlink control information DCP for the UE, the DCP is sent according to the determined time domain starting position of the wake-up signal in the DRX long period.

If the UE is configured with both DRX long cycle and DRX short cycle, after the DRX short cycle is started, the UE will monitor control channels such as PDCCH according to the DRX long cycle after the DRX short cycle timer (drx-ShortCycleTimer) times out.

Without using the technical solution provided by the embodiment of the present application to determine the time domain starting position of the wake-up period, the time domain starting positions of the DRX long period and DRX short period wake-up periods (onduration) are as follows:

For the DRX short cycle of the DRX group, if the initial offset value is drx-StartOffset, then according to the formula [(SFN×10)+subframe number]modulo(drx-ShortCycle)=(drx-StartOffset)modulo(drx-ShortCycle), Adjust the starting position of the previous time domain when the DRX cycle wakes up.

The SFN is the frame number of the current wireless frame; subframe number is the subframe number of the current wireless subframe; drx-ShortCycle is the count value of the current DRX short cycle. Among them, drx-StartOffset is the starting adjustment amount. drx-LongCycle is the current DRX long cycle count value.

The embodiment of this application determines the starting position of the time domain of the wake-up moment:

At this time: According to the formula (SFN×10)+subframe number]modulo(drx-ShortCycle)=(drx-StartOffset+floor((Index modulo M)/N)*offset)modulo(drx-ShortCycle), after adjustment The time domain starting position to initiate the wake period. Among them, (floor((Index modulo M)/N) is the adjustment amount provided in conjunction with this embodiment. That is, the starting position of the time domain of the wake-up period of the DRX cycle is adjusted.

The drx-StartOffset here is the amount agreed by the network device or protocol.

In the starting radio frame after drx-SlotOffset, the DRX short period is counted within the timing duration of drx-onDurationTimer.

For DRX long cycle, [(SFN×10)+subframe number]modulo(drx-LongCycle)=drx-StartOffset:

The DRX mechanism includes at least one of the following timers (or timers):

The general configuration parameters of the DRX mechanism may include at least one of the following:

Wake-up timer (drx-onDurationTimer): duration at the beginning of the DRX cycle.

Slot offset (drx-SlotOffset) timer: delay before starting drx-onDurationTimer.

Activation timer (drx-InactivityTimer): For the current MAC entity, the duration after the PDCCH indicates a new uplink or downlink transmission.

The downlink retransmission timer (drx-RetransmissionTimerDL) is used for retransmission of the downlink Hybrid Automatic Repeat Request (HARQ) process in addition to broadcast, until the maximum duration until the downlink retransmission is received.

The uplink retransmission timer (drx-RetransmissionTimerUL) is used for retransmission of the uplink HARQ process until the maximum duration until the uplink grant for uplink retransmission is received.

DRX long cycle start offset (drx-LongCycleStartOffset) timer: indicates the DRX long cycle (drx-LongCycle) and start adjustment value (drx-StartOffset), and specifies the starting position of the long and DRX short cycles.

DRX short cycle (drx-ShortCycle) timer: DRX short cycle.

drx-ShortCycleTimer: The UE adopts the duration of the DRX short cycle.

drx-HARQ-RTT-TimerDL, used for downlink HARQ transmission except broadcast, the minimum duration before expected reception of downlink resource allocation control signaling for downlink HARQ retransmission.

drx-HARQ-RTT-TimerUL, used for uplink HARQ process transmission, the expected minimum duration before receiving uplink grant signaling for uplink HARQ retransmission.

The value range of DRX long cycle (drx-LongCycle) in the general DRX configuration is: 10ms, 20ms, 32ms, 40ms, 60ms, 64ms, 70ms, 80ms, 128ms, 160ms, 256ms, 320ms.

The value range of DRX short cycle (drx-ShortCycle) is: 2ms, 3ms, 4ms, 5ms, 6ms, 7ms, 8ms, 10ms, 14ms, 16ms, 20ms, 30ms, 32ms, 35ms, 40ms, 64ms, 80ms, 128ms, 160ms, 256ms, 320ms, 512ms, 640ms.

With the enrichment of business forms, extended reality (eXtended Reality, XR) has emerged. A typical XR stream generates video frames in a periodic manner, and the typical video frame rate is 30 frames or 60 frames per second, that is, the video frame interval is 33.33 or 16.66 milliseconds (millisecond, ms).

Augmented Reality (AR) or Virtual Reality (VR) services provide users with video streaming services and have higher latency requirements than traditional video streaming services.

Extended reality (eXtended Reality, XR) business is a kind of business that 5G system needs to support.

A typical XR service is a fixed frame rate service, that is, there is a fixed period for service data to arrive at the UE, but there will be additional delay jitter (Jitter) above the fixed period, causing the actual data service to arrive at the UE earlier or earlier. put off.

A possible example of what the XR service can achieve is a frame rate of 60 frames per second (FPS), that is, a period of 16.67ms, and a jitter range of [4, -4]ms.

Since the data arrival cycle is a non-integer multiple of the DRX cycle, the data arrival time will gradually drift, and even gradually drift out of the wake-up period (onduration) range, as shown in Figures 4 and 5.

Embodiments of the present disclosure provide an information processing method that can protect the adjustment of the time domain starting position of onduration in a connected state to adapt to the transmission of non-periodic services and reduce the delay of service transmission.

For the time domain starting position of long-period and short-period ondurtaion, the adjustment method is as follows:

Method 1: The time domain starting position of the long/short period ondurtaion is adjusted according to the DRX cycle.

Illustratively: the UE counts the current DRX cycle, such as the first DRX cycle (that is, when the onduration timer is started for the first time), the second DRX cycle...

The time domain starting position of the wake-up period can be adjusted by 1 or N DRX cycles per interval (N is).

The adjustment amount (which may also be called an adjustment value) is pre-agreed by the protocol, notified by the network, or determined in combination with the index of the current DRX cycle.

As an example, if the time domain starting position of the wake-up period is adjusted once in each DRX cycle, the adjustment amount of the time domain starting position of the wake-up period in the DRX cycle can be as follows:

The first DRX cycle adjustment amount is 0;

The second DRX cycle adjustment amount is offset;

The third DRX cycle adjustment amount is 2*offset;

…

As an embodiment, if the time domain starting position of the wake-up period is adjusted every N DRX cycles, the adjustment amount of the first to Nth DRX cycles is 0;

The N+1 to 2Nth DRX cycle adjustment amount is offset;

The 2Nth to 2N+1th DRX cycle adjustment amount is 2*offset;

For example, the offset here is the aforementioned first value. In the embodiment of the present disclosure, the index of the DRX cycle starts from 0.

As an embodiment, the adjustment amount may be directly notified to the UE by the network device.

The adjustment amount of the first DRX cycle can be k*offset or deta T; k here can be one of the aforementioned offset factors.

k originates from the base station notifying the UE, or from the core network notifying the UE.

For example, k is the sequence number of the downlink data packet sent by the network, which can be determined by the base station according to the designation of the core network.

At this time, deta T can be an adjustment amount determined by the network combined with auxiliary information from the core network. For example, the sequence number of the service data packet just sent to the UE is obtained from the core network, and the base station obtains an adjustment amount according to its own algorithm.

For example, the k may be the sequence number or number of the downlink data packet sent by the base station in the current DRX cycle or in this N DRX cycles. The k can be specified by the core network equipment to the base station, and the base station further informs the UE. For example, the core network device may be determined based on the amount of data cached for the UE.

When performing every interval adjustment or N-interval DRX cycle adjustment; after an interval of M adjustments, the adjustment will start from the initial value (such as 0).

For example, if N is 3 and M is 24, that is, in the 24th DRX cycle, the adjustment amount will become 0;

For the short-period ondurtaion starting point (in addition to the above methods), the adjustment method can also be:

The count of the current DRX cycle can be as follows:

Method 1: Start or restart drx-ShortCycleTimer after entering the short cycle), which is considered to be the first time to start the onduration timer, that is, the first DRX cycle (that is, the first time to start the onduration timer), the second DRX cycle...

As a preferred embodiment:

According to starting from drx-ShortCycleTimer, start counting DRX cycles (that is, starting from the initial value after restarting (reset), such as counting from 0 or 1).

Method 2: Count along the long-cycle DRX cycle count:

For example: before the UE enters the DRX short cycle, the DRX long cycle is the Nth cycle, then the onduration timer is started for the first time after entering the DRX short cycle, that is, the N+1th DRX cycle...

Regarding whether the restart of drx-ShortCycleTimer affects the count value of the DRX cycle counter:

Method 1: Restarting drx-ShortCycleTimer will cause the counting value of the DRX cycle counter to not restart;

Method 2: Restarting drx-ShortCycleTimer will not cause the count value of the DRX cycle counter to restart;

As an example,

The UE count follows the DRX cycle count in the DRX long cycle: for example: before the UE enters the DRX short cycle, the DRX long cycle is the Nth cycle, then the onduration timer is started for the first time after entering the DRX short cycle, that is, the N+1th DRX cycle... And the subsequent restart of drx-ShortCycleTimer will not cause the counting value of the DRX cycle counter to continue to accumulate.

As a preferred embodiment:

When the terminal starts the onduration counter for the first time, it counts the start of the DRX cycle and assigns an initial count value (0 or 1); after that, when the onduation timer starts again, the DRX cycle is accumulated based on the DRX cycle counted by the previous onduration counter. , wherein the switching of the DRX long period and the DRX short period will not affect the count of the DRX period.

The adjustment amount can be determined as follows:

Method 1: The adjustment amount of the first short-period DRX cycle is the same as the adjustment amount of the most recently used long-period onduration before entering the short cycle;

Method 2: The adjustment amount of the first short-period DRX cycle is determined by the adjustment amount of the most recently used long-period onduration before entering the short cycle, for example, adding an offset; the offset can be the aforementioned second offset value. The second offset value may be equal to the aforementioned first offset value or not equal to the first offset value.

Method 3: The adjustment amount of the first short cycle DRX cycle is determined based on the latest authorization before entering the short cycle or the information carried by the received MAC CE;

As an embodiment, the MAC CE carries the adjustment amount of the DRX cycle of the first short cycle after the UE enters the short cycle.

As an embodiment, for the adjustment amount of the time domain starting position of the wake-up period (ondurtaion) of the DRX long period and/or the DRX short period, the UE can report the expected adjustment amount to the network: the adjustment amount expected by the UE It can be carried as auxiliary information and reported to the network device.

As an embodiment, only the time domain starting position of the DRX short-cycle wake-up period (ondurtaion) can be adjusted based on the agreement, while the time-domain starting position of the DRX long-cycle wake-up period (ondurtaion) is not adjusted.

As an embodiment, for a dual DRX scenario, the adjustment values of the time domain starting positions of the wake-up periods of the DRX long period and/or the DRX short period of the two DRX packets are consistent.

As an embodiment, for long-period DRX, if DCP is configured, the search space of DCP is determined, and its offset starting point will be the time domain starting position of the adjusted onduration (that is, the starting point of the domain); or other The offset starting point will be the time domain starting position of the onduration before adjustment (that is, it will not be affected by the adjustment of the onduration starting point).

As an example:

Starting after starting drx-onDurationTimer, based on the current drx-StartOffset (starting adjustment value) and adding floor((Index modulo M)/N)*offset (that is, the adjustment amount determined by the sequence number of the DRX cycle), it will Get the final adjusted time domain starting position of the current DRX cycle. Among them, floor means rounding down.

At this time: According to the formula (SFN×10)+subframe number]modulo(drx-ShortCycle)=(drx-StartOffset+floor((Index modulo M)/N)*offset)modulo(drx-ShortCycle), after adjustment The start position of the wake-up period time domain. That is, the starting position of the time domain of the wake-up period of the DRX cycle is adjusted.

The SFN is the frame number of the current wireless frame; subframe number is the subframe number of the current wireless subframe; drx-ShortCycle is the count value of the current DRX short cycle. Among them, drx-StartOffset is the starting adjustment amount.

Index may be the current DRX cycle count value of the UE. At this time, the adjustment amount needs to be determined based on the count value of the DRX cycle and the offset issued by the network.

By way of example:

N means adjustment every 3 DRX cycles, and M means that after M DRX cycles, the adjustment amount will return to 0.

For example, if N is 3 and M is 24, that is, in the 24th DRX cycle, the adjustment amount will become 0.

When the index is 0, 1, 2, the adjustment amount is 0; that is, the adjustment amount in the 0th, 1st, and 2nd periods is 0; when the index is 3, 4, and 5, the adjustment amount is 1*offset; that is, the adjustment amount in the 3rd, 1st, and 2nd periods is 1*offset; 4. The adjustment amount of the five DRX cycle wake-up periods is an offset;

When the index is 6, 7, and 8, the adjustment amount is 2*offset; that is, the adjustment amount during the wake-up period of the 6th, 7th, and 8th DRX cycles is 2 offsets;

…

When the index is 24, 25, and 26, the adjustment amount is 0; that is, the adjustment amount for the 24th, 25th, and 26th DRX cycle wake-up period is 0.
