As shown in Figure 2, On Duration appears periodically, and the specific period is implemented by the configuration of network-side equipment such as base stations. In order to achieve the purpose of UE power saving and avoid excessive transmission delay between the base station and UE, the concepts of DRX Long Cycle and DRX Short Cycle are introduced. In the DRX short cycle, On Duration occurs more frequently than in the DRX long cycle. If the UE is configured with both DRX long cycle and DRX short cycle, after the DRX short cycle is started, the UE will listen according to the DRX long cycle after the DRX end cycle timer (drx-ShortCycletimer) of the DRX short cycle times out.

Among them, the starting point of OnDuration for DRX long period and DRX short period is as follows:

If DRX short period is used in the DRX group and expression (1) is satisfied:

[(SFN×10)+subframe number]modulo(drx-ShortCycle)＝(drx-StartOffset)modulo(drx-S hortCycle) (1)

After delaying drx-SlotOffset at the starting position of the subframe, start the DRX duration timer (drx-OnDurationtimer).

If DRX long period is used in the DRX group and expression (2) is satisfied:

[(SFN×10)+subframe number]modulo(drx-LongCycle)＝drx-StartOffset (2)

After delaying drx-SlotOffset at the starting position of the subframe, start the DRX duration timer (drx-OnDurationtimer).

○drx-OnDurationtimer: The time interval starting from the DRX cycle, this period is the active time (active time)

○drx-SlotOffset: time delay before starting drx-OnDurationtimer

○drx-Inactivitytimer: For the current MAC entity, the duration after the PDCCH indicates a new uplink or downlink transmission.

○drx-RetransmissiontimerDL (used for downlink HARQ (Hybrid Automatic Repeat Request, Hybrid Automatic Repeat Request) process except broadcast): The maximum duration until a downlink retransmission is received.

○ drx-RetransmissiontimerUL (for uplink HARQ process): The maximum duration until the uplink grant for uplink retransmission is received.

○drx-LongCycleStartOffset: Indicates the DRX long cycle (drx-LongCycle) and start offset (drx-StartOffset), and specifies the starting position of the long and short DRX cycles.

○drx-ShortCycle (optional): DRX short cycle.

○drx-ShortCycletimer (optional): The UE adopts the duration number of the DRX short cycle. Indicates how many subframes last in the short period without receiving PDCCH before entering the long period.

○ drx-HARQ-RTT-timerDL (for downlink HARQ except broadcast): The minimum duration before the MAC entity is expected to receive downlink resource allocation control signaling for downlink HARQ retransmission.

○ drx-HARQ-RTT-timerUL (for uplink HARQ process): The minimum duration before the MAC entity is expected to receive uplink grant signaling for uplink HARQ retransmission.

Among them, 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), DRX short cycle ( The value range of 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).

Extended Reality (XR) business is one of the business types that 5G systems need to support. XR includes AR/VR/Cloud gaming and so on. Typical characteristics of XR services are that for services with a fixed frame rate, there is a fixed period for the service 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 later. The schematic diagram of the XR service arrival model is shown in Figure 3: (A possible example is a frame rate of 60FPS (Frame per second), that is, the period is 16.67ms, and the jitter range is [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 onduration range. The data arrival time drift is shown in Figure 4.

It can be agreed that the terminal adjusts the starting point of onduration at the starting point of the DRX cycle. However, when the terminal switches to a base station, the high-level services still maintain continuous packet sending. However, for the MAC layer of the access network equipment (RAN), a reset of the MAC entity has occurred. How to Setting the terminal onduration starting point after switching base stations to reduce the impact on data transmission is an urgent problem that needs to be solved.

As shown in Figure 5, an embodiment of the present disclosure provides a method for determining a duration starting position, which is executed by a communication device, including:

Step 501: Based on predetermined information, determine the first adjustment offset value of the duration starting position in at least one first DRX cycle, wherein the first DRX cycle includes: the first adjustment offset value associated with the DRX configuration parameter after the UE performs base station switching. One DRX cycle.

Here, the communication device may include a network-side device such as a base station, or a terminal-side device such as a UE.

In a possible implementation, the communication device includes at least one of the following: a UE, a source base station in base station switching, and a target base station in base station switching.

The first adjustment offset value of the starting position of the duration in the first DRX cycle may be determined by the UE and the target base station based on predetermined information. In this way, the UE and the target base station can perform data transmission based on the determined starting position of the duration in the first DRX cycle after completing the base station handover.

In a possible implementation, the source base station may also determine the first adjustment offset value of the starting position of the duration in the first DRX cycle and indicate it to the target base station.

In a possible implementation, the UE may be a UE in the RRC connected state.

In a possible implementation, the network side device and the UE may determine the first adjustment offset value of the duration starting position in the first DRX cycle based on the same predetermined information.

In a possible implementation, the first DRX cycle may be a long DRX cycle or a short DRX cycle.

In one embodiment, different first DRX cycles are associated with different DRX configuration parameters.

In a possible implementation, the communication device can be configured with at least one DRX configuration parameter. Different DRX cycles are associated with different DRX configuration parameters. Different DRX configuration parameters have respective corresponding first DRX cycles.

For example, the communication device can configure two DRX configuration parameters: DRX configuration parameter 1 and DRX configuration parameter 2; then, there is the first DRX cycle 1 corresponding to DRX configuration parameter 1, and the first DRX cycle 2 corresponding to DRX configuration parameter 2. . The first DRX cycle 1 and the first DRX cycle 2 have at least one of the following differences: cycle length; cycle starting position; and duration.

The duration start position can be the starting time domain position of the duration.

The duration of the first DRX cycle may be the first duration of the first DRX cycle after the UE performs base station switching. That is, the starting position of the duration in the first DRX cycle may be the moment when the UE first starts the duration timer (OnDuration Timer) after performing base station switching.

Here, the first adjustment offset value is different from drx-SlotOffset or drx-StartOffset in Expression (1) or Expression (2). The first adjustment offset value is a further adjustment value based on the original position for the duration determined based on expression (1) or expression (2).

In a possible implementation, the starting position of the duration in the first discontinuous reception DRX cycle is: the determined subframe extension drx-SlotOffset plus the first adjustment offset value.

In a possible implementation, the communication device may first determine the starting position of the duration in the first DRX cycle based on expression (1) or expression (2), and then adjust the original position based on the first adjustment offset value , get the final starting position of the duration in the first DRX cycle.

In a possible implementation, the predetermined information can be used to directly indicate the first adjustment offset value,

In a possible implementation, the predetermined information may be used to indicate at least one of the following for calculating the first adjustment offset value: calculation method; calculation parameter.

In a possible implementation, the offset value can be determined based on the duration adjustment of the UE before base station switching, so that the offset value of the duration can meet the requirements of the duration position of data transmission before and after base station switching. needs to reduce data transmission delay.

The predetermined information may be agreed upon in a protocol or mutually agreed upon between the communication devices.

In this way, after the UE performs base station switching, the first adjustment offset value of the duration starting position in the DRX cycle is determined based on the predetermined information, thereby adjusting the duration starting position to meet the data transmission due to jitter after the base station switching. Changes in arrival time caused by other reasons require duration and position adjustment to meet the transmission needs of different data services.

Furthermore, the adjustment of the starting position of the duration reduces the situation where the transmission needs to be performed within the subsequent duration due to the inconsistency between the duration and the data arrival time, thereby reducing the data transmission delay.

In one embodiment, the relationship between the first adjustment offset values of the at least one first DRX cycle includes at least one of the following:

The first adjustment offset values of the first DRX cycle associated with different DRX configuration parameters are the same;

The first adjustment offset value of the first DRX cycle associated with different DRX configuration parameters is different.

For the network side to configure multiple DRX configuration parameters for the UE, the first DRX cycle of different DRX configuration parameters, that is, the same first adjustment offset value can be used for different first DRX cycles. That is, different DRX configuration parameters can use the same first adjustment offset value.

For the network side to configure multiple DRX configuration parameters for the UE, different first DRX cycles of different DRX configuration parameters, that is, different first DRX cycles, may use different first adjustment offset values. A first adjustment offset value may be configured for different first DRX cycles respectively. That is, different DRX configuration parameters may adopt different first adjustment offset values.

In this way, the configuration flexibility of the first adjustment offset value of the duration in the first DRX cycle is improved.

As shown in Figure 6, an embodiment of the present disclosure provides a method for determining a duration starting position, which is executed by a communication device and includes one of the following:

Step 601a: Based on the communication protocol, determine a first adjustment offset value of at least one duration starting position in the first DRX cycle;

Step 601b: Determine the first adjustment offset value of the starting position of the duration in at least one first DRX cycle based on the network sending predetermined information to the UE;

Step 601c: Determine the first adjustment offset value of the duration start position in the first DRX cycle based on the second adjustment offset value of the duration start position in the second DRX cycle, wherein the first The second DRX cycle at least includes: the last DRX cycle before the UE performs the base station switching;

Step 601d: Determine the first adjustment offset value based on the index value and index offset value of the second DRX cycle. Here, the first adjustment offset value may be specified by the communication protocol. After the UE performs base station switching, the first adjustment offset value of the first DRX cycle may be determined based on the regulations of the communication protocol.

The communication device may perform one of steps 601a to 601d to determine the first adjustment offset value.

In a possible implementation, the first adjustment offset value specified by the communication protocol may be 0.

In a possible implementation, the network side equipment may include access network equipment such as base stations, and may also include core network equipment.

In a possible implementation, the predetermined information may be carried in a command sent by the base station to the UE related to base station switching.

In a possible implementation, the response and configuration include multiple DRX configuration parameters, and the first adjustment offset value indicated by the predetermined information sent by the network side device may be for each first DRX cycle (that is, equivalent to one DRX cycle). The configuration parameter corresponds to a first adjustment offset value), or the first adjustment offset value indicated by the predetermined information sent by the network side device may be for the entire first DRX cycle (that is, it is equivalent to all DRX configuration parameters corresponding to a first adjustment offset value). First adjust the offset value).

The communications device may determine the first adjustment offset value based on the second adjustment offset value.

In a possible implementation, the determined first adjustment offset value may have a correlation relationship with the second adjustment offset value. The first adjustment offset value may be a continuation of the second adjustment offset value after the UE performs base station switching. The predetermined information may be associated with the second adjustment offset value of the duration start position in the second DRX cycle. For example, the first adjustment offset value may be equal to the second adjustment offset value. Alternatively, the first adjustment offset value may be the second adjustment offset value determined through a preset algorithm, wherein the variables in the preset algorithm may include but are not limited to: the interval between the first DRX cycle and the second DRX cycle. duration. In this way, the UE can have continuity in the adjustment offset value for the starting position of the duration before and after base station switching, thereby meeting the continuity requirement of data transmission.

In a possible implementation, the predetermined information may be used to indicate at least one of the following: a second adjustment offset value, and a calculation parameter of a preset algorithm for determining the first adjustment offset value through the second adjustment offset value.

In one embodiment, the first DRX cycle and the second DRX cycle correspond to the same DRX configuration parameter;

or,

The first DRX cycle and the second DRX cycle correspond to different DRX configuration parameters.

The second DRX cycle may be the last DRX cycle of a DRX configuration parameter before the UE performs base station switching, and the first DRX cycle may be the first DRX cycle of the same DRX configuration parameter after the UE performs base station switching. That is, there is no other cycle associated with the DRX configuration parameter between the second DRX cycle and the first DRX cycle.

The second DRX cycle may be the last DRX cycle for one DRX configuration parameter before the UE performs base station switching (for example, the second DRX cycle may be the last DRX cycle for all DRX configuration parameters before the UE performs base station switching), and the first The DRX cycle may be the first DRX cycle of another DRX configuration parameter after the UE performs base station switching (for example, the first DRX cycle may be the first DRX cycle of all DRX configuration parameters after the UE performs base station switching). That is, there are no other cycles associated with any DRX configuration parameters between the second DRX cycle and the first DRX cycle.

In a possible implementation, determining the first adjustment offset value based on the second adjustment offset value of the duration starting position in the second DRX cycle includes:

Determine the second adjustment offset value as the first adjustment offset value;

The sum of the second adjustment offset value and a predetermined offset value is determined as the first adjustment offset value.

In a possible implementation, the first adjustment offset value may be equal to the second adjustment offset value.

In a possible implementation, the first DRX cycle and the second DRX cycle have the same type of DRX configuration parameters.

For example, the first DRX period corresponds to the long-period DRX parameter, and the second DRX period corresponds to the long-period DRX parameter.

In a possible implementation, the first DRX cycle and the second DRX cycle have different DRX configuration parameters of the same type.

For example, the first DRX period corresponds to the long-period DRX parameter, and the second DRX period corresponds to the short-period DRX parameter.

For example, the first adjustment offset value may continue to adopt the second adjustment offset of the duration of the long period or short period recently used before the base station is switched.

In a possible implementation, the first adjustment offset value may be the sum of the second adjustment offset value and the predetermined offset value, wherein the sum of the predetermined offset values may be associated with: the first DRX cycle and the second DRX The length of time between cycles. For example, the predetermined offset value is positively related to the interval length between the first DRX cycle and the second DRX cycle.

For example, the first adjustment offset value may continue to adopt the second adjustment offset value of the duration of the long period or short period recently used before the base station switching plus the predetermined offset value.

In a possible implementation, different index values are associated with different first adjustment offset values.

For example, index values 1, 2, and 3 respectively correspond to 1*offset value, 2*offset value, 3*offset value, and so on, which will not be described again here.

In a possible implementation, the index value associated with the DRX cycle includes: the cycle ordinal number of the DRX cycle.

For example, index values 1, 2, and 3 respectively correspond to the first DRX cycle, the second DRX cycle, the third DRX cycle corresponding to the DRX configuration parameters, and so on, which will not be described again here.

In a possible implementation, multiple different index values are associated with the same first adjustment offset value.

In a possible implementation, the first adjustment offset value associated with the index value may change periodically.

For example, starting from index value 1, three index values correspond to the same duration offset value (the first adjustment offset value). The duration offset value can increase with the increase of the index value, and the duration offset value The value changes periodically with 24 index values.

For example, the index value is the number of DRX cycles. In the 1st DRX cycle, 2nd DRX cycle and 3rd DRX cycle, the corresponding duration offset value is 0; in the 3rd DRX cycle, 4th DRX cycle and In the 5th DRX cycle, the corresponding duration predetermined offset value is 1*offset; in the 6th DRX cycle, the 7th DRX cycle and the 8th DRX cycle, the corresponding duration predetermined offset value is 2*offset;… In the 24th DRX cycle, the 25th DRX cycle and the 26th DRX cycle, the corresponding duration predetermined offset value is 0.

In a possible implementation, determining the first adjustment offset value based on the index value and index offset value of the second DRX cycle includes:

The index value of the second DRX cycle is added to the index offset value to determine the index value of the first DRX cycle;

The first adjustment offset value is determined based on an index value of the first DRX cycle, where different index values are associated with different adjustment offset values.

Here, the index value may be a count value of the DRX cycle, that is, the index of the DRX cycle is counted, and different index values are associated with different adjustment offset values.

In a possible implementation, the predetermined information may be used to indicate at least one of the following: an index value of the second DRX cycle; an index offset value.

For example, the index value of the second DRX cycle is Index and the index offset value is indexex1. After the UE performs base station switching, the index value of the first DRX cycle is Index+Indiex1.

The corresponding relationship between different index values and the adjustment offset value can be agreed upon in advance or stipulated in a communication protocol. The communication device may determine the corresponding first adjustment offset value based on Index+Indiex1.

In one embodiment,

The index offset value is specified by the communication protocol; or,

The index offset value is notified to the UE by the network side device.

In a possible implementation, the index offset value is positively related to the interval duration between the first DRX cycle and the second DRX cycle.

In a possible implementation, the index value of the first DRX cycle and the index value of the second DRX cycle may be the cycle ordinal number of the first DRX cycle and the cycle ordinal number of the second DRX cycle respectively. The index offset value can be the number of DRX cycles.

For example, the index offset value may be agreed to be 1 by the communication protocol. That is, one DRX cycle added on the basis of the index value of the second DRX cycle is used as the index value of the first DRX cycle.

In one embodiment, the index offset value includes: the number of cycles of the first DRX cycle that can be included in the duration of the base station switching.

For example: the estimated base station handover duration is 100ms, and if the first DRX cycle after handover is 20ms, the index offset value is 5 first DRX cycles. This parameter can be estimated by the network and then notified to the terminal.

Step 1001: Send auxiliary information to the target base station, where the auxiliary information is used to indicate whether the UE supports adjustment of the duration starting position.

The source base station may send assistance information indicating the adjustment capability of the duration starting position of the UE to the target base station. After receiving the assistance information, the target base station can determine whether the UE has the adjustment capability. In this way, the target base station can determine whether the UE supports adjusting the duration starting position.

As shown in Figure 11, the embodiment of the present disclosure provides a duration starting position determination method, which is executed by the target base station, including:

Step 1101: In response to the assistance information indicating that the UE supports adjustment of the duration start position, based on the predetermined information, determine the first adjustment of the duration start position in at least one of the first DRX cycles. offset value.

When the target base station determines that the UE supports the duration start position for adjustment, it adjusts the duration start position of the UE in the first DRX cycle based on predetermined information.

In order to further explain any embodiment of the present disclosure, a specific example is provided below.

1. Protect a method of setting the starting point of the initial duration (onduration) in the RRC connected state UE base station handover scenario;

2. After the switch is successful, the initial duration starting position of the long period will be adjusted as follows:

The terminal counts the current DRX cycle, such as the first DRX (cycle) cycle, that is, the DRX cycle in which the duration timer (onduration timer) is started for the first time after the handover is successful.

a) Method 1: The initial duration starting point position adjustment value (first adjustment offset value) of the first DRX cycle (i.e. the first DRX cycle) after the handover is successful is the value agreed upon in the agreement;

As an embodiment, the protocol agreed value is 0;

b) Method 2: The initial duration starting point position adjustment value (first adjustment offset value) of the first DRX cycle (i.e. the first DRX cycle) after the handover is successful is the network notification value;

As an embodiment, the network notification value (first adjustment offset value) is notified by the base station to the UE through a handover command;

As an embodiment, if multiple sets of DRX parameters (DRX configuration parameters) are configured, the network notification value (first adjustment offset value) is notified by the base station to the terminal through a handover command, which can be an adjustment for each set of DRX parameters. value (the first adjustment offset value), that is, each set of parameters is performed separately; it can also be a unified value, and multiple sets of DRX parameters are adjusted uniformly;

c) Method 3: The adjustment value of the starting point position of the initial duration of the DRX cycle of the first cycle after the switch is successful is determined by the adjustment value of the duration of the second DRX cycle (long cycle or short cycle) most recently used before the switch (the second adjustment bias). Shift value) OK,

As an embodiment: the adjustment value (first adjustment offset value) of the duration of the long period or short period recently used before the switch can be continued to be used;

As an example: you can continue to use the adjustment value of the duration of the long period or short period recently used before the switch plus an offset (predetermined offset value);

d) Method 4: The initial DRX cycle start position adjustment value of the first cycle after the switch is successful is determined by the DRX cycle index of the second DRX cycle (long cycle or short cycle) most recently used before the switch. value) determined,

As an example:

After the switch is successful, the first DRX cycle (that is, the first start of the duration timer after the switch is successful) can continue to add indexex1 to the Index before the switch (the index value of the second DRX cycle). (index offset value);

Then add index and indiex1 to get the DRX cycle of the first cycle after the switch is successful (the first DRX cycle)

Initial duration starting point position adjustment value (first adjustment offset value)

1) index1 can be the number of DRX cycles notified by the network in the handover command; as an example, if the handover duration is expected to be 100ms, then if the DRX cycle after handover is 20ms, it is set to 5 additional DRX cycles, That is, index1 is 5;

2) index1 can be a protocol stipulation, such as an additional DRX cycle;

3. If after handover, multiple sets of DRX long periods (multiple sets of DRX long period parameters) are configured for the UE, regarding adjusting the starting point of the initial duration of the long period:

a) Adjustment can be made for at least one set of DRX duration starting points, that is, adjusting the initial duration starting point position adjustment value of the first DRX cycle of the set of DRX parameters.

b) The above adjustment rules and adjustment parameters can be performed for a certain DRX cycle or for all DRX cycles; as an example:

For the first set of DRX parameters (DRX configuration parameters) after the switch is successful, the initial duration start position adjustment value of the first DRX cycle of this set of DRX parameters is 0, that is, no starting point adjustment is performed; for the second set of DRX parameters after the switch is successful, Among the DRX parameters (DRX configuration parameters), the initial duration starting point position adjustment value of the first DRX cycle of the set of DRX parameters is offset, that is, the starting point of the duration is adjusted.

As an embodiment: among the multiple sets of DRX parameters (DRX configuration parameters) after successful handover, the initial duration start position adjustment value of the first DRX cycle corresponding to each set of DRX parameters is all offset, that is, the same The starting point adjustment;

4. The source base station can provide auxiliary information to the target base station regarding adjusting the starting position of the initial duration of the long period:

a) Whether the terminal has the ability to adjust the starting point of the DRX duration:

b) The historical value of the DRX duration start point adjustment by the source base station or the DRX duration start point adjustment value recently used by the terminal before handover; (can be the adjustment value of each set of DRX parameters, or if it is performed separately for each set of parameters, it can also be A unified value, if multiple sets of parameters are adjusted uniformly)

The standard specifies how to calculate the adjustment value through DRX cycle:

if the Short DRX cycle is used for a DRX group and[(SFN×10)+subframe number]modulo(drx-ShortCycle)＝(drx-StartOffset)modulo(drx-ShortCycle):

start drx-onDurationTimer for this DRX group after drx-SlotOffset plus floor((i modulo M)/N)*offset from the beginning of the subframe.

That is: if a short DRX cycle is used and [(SFN×10)+subframe number]modulo(drx-ShortCycle)=(drx-StartOffset)modulo(drx-ShortCycle) is satisfied, then the DRX duration timer (drx-onDurationTimer ) is the delay drx-SlotOffset plus floor((i modulo M)/N)*offset after the subframe. floor((i modulo M)/N)*offset is to adjust the offset value. That is, the index of the DRX cycle is counted, and different index values are associated with different adjustment offset values.

Among them, M and N are predetermined values, i is the ordinal number of the DRX cycle, and offset is the offset value.

For example, N is 3 and M is 24, that is, in the 24th (i=24) DRX cycle, the adjustment value will become 0, that is, drx-StartOffset and drx-SlotOffset are used to determine the starting offset of the onduration, and no additional adjustments are required. value.

For example, taking the predetermined offset value = floor((i modulo M)/N)*offset as an example, in the first DRX cycle, the second DRX cycle and the third DRX cycle, the corresponding duration predetermined offset value is 0; In the 3rd DRX cycle, 4th DRX cycle and 5th DRX cycle, the corresponding duration predetermined offset value is 1*offset; that is, the basis for determining the starting position of onduration based on drx-StartOffset and drx-SlotOffset On, additional accessories and additional adjustment values are required, the effect of which is that the onduration start position is delayed.

In the 6th DRX cycle, the 7th DRX cycle and the 8th DRX cycle, the corresponding duration predetermined offset value is 2*offset;... In the 24th DRX cycle, the 25th DRX cycle and the 26th DRX cycle , the corresponding duration predetermined offset value is 0.
