Background technique

In the Extended Reality (XR) business model, the arrival intervals of business packets are equal, and the intervals are small floating-point numbers (non-positive integers). In addition, XR services have very high latency requirements, and the air interface transmission packet delay budget (Packet Delay Budget, PDB) is required to be around 10ms. In order to achieve terminal energy saving under XR services, the network can configure a short Discontinuous Reception (DRX) timer (timer), but at the same time it needs to ensure a good fit with the business model to complete packet transmission within the PDB. However, current relevant standards cannot configure a DRX configuration that meets the arrival of service packets. This will cause a mismatch between the service packet arrival cycle and the DRX cycle, which will largely result in the service packet being unable to complete transmission within the PDB and being discarded.

Extended reality (XR) refers to all real and virtual combined environments and human-computer interactions generated by computer technology and wearable devices. It includes representative forms such as augmented reality (Augmented Reality, AR), mixed reality (Mixed Reality, MR), virtual reality (Virtual Reality, VR), and the interpolation areas between them.

2. Radio Resource Control (RRC) connection state discontinuous reception (Discontinuous Reception, DRX).

A basic DRX cycle (DRX cycle) consists of "Duration (On Duration)" and "Opportunity for DRX": During the "On Duration" time, the User Equipment (User Equipment, UE) monitors physical downlink control Channel (Physical Downlink Control Channel, PDCCH); During the "Opportunity for DRX" time, the UE does not monitor the PDCCH to save power consumption.

3. DRX timer.

Combined with the above DRX model, the following description of the DRX timer is given.

The DRX duration timer (drx-onDurationTimer) is started only once per DRX cycle, and the duration formed by drx-onDurationTimer is located at the starting position of the DRX cycle.

When corresponding to Media AccessControl, When the MAC) receives a DRX command (DRX Command) or a long-term (Long) DRX command MAC control element (Control Element, CE), the Timer is stopped.

DRX slot offset, which is used to determine the delay before starting drx-onDurationTimer.

The information transmission method provided by the embodiments of the present application will be described in detail below with reference to the accompanying drawings through some embodiments and application scenarios.

As shown in Figure 2, this embodiment of the present application provides an information transmission method, including:

Step 201: The terminal obtains discontinuous reception DRX-related configuration information. The DRX-related configuration information includes M pieces of DRX starting offset information, where M is a positive integer greater than 1.

The above-mentioned DRX start offset information is used to determine the starting subframe of the DRX duration (onduration) or the starting subframe of the DRX cycle (cycle). Optionally, the DRX start offset information used to determine the starting subframe of the DRX duration can be understood as the DRX start offset corresponding to or associated with or determining the DRX onduration.

Optionally, the above M pieces of DRX start offset information correspond to the same DRX cycle.

Optionally, the value of the above M is 3, 6 or 9.

Optionally, the above-mentioned M DRX starting offsets correspond to at least one set of DRX configurations, where one set of DRX configurations includes one or more DRX parameters. For example, a set of DRX configuration contains the following DRX parameters:

DRX cycle;

DRX duration timer (DRX onduration timer);

DRX inactivity timer;

DRX retransmission related timer;

DRX slot offset (drx-SlotOffset), the DRX slot offset is the offset between the start time of the DRX duration timer and the starting position of the starting subframe of the DRX cycle (the delay before starting the drx-onDurationTimer);

Relevant configuration of energy-saving downlink control information (DCI). The energy-saving downlink DCI is used to indicate whether to perform PDCCH monitoring. The energy-saving DCI can be specifically through a power saving-Radio Network Temporary Identifier (RNTI). DCI scrambled with cyclic redundancy check (CRC). superior The above related configuration can also be described as physical layer energy saving indication (DCI with CRC scrambled by PS-RNTI, DCP) related configuration. DCP refers to the DCI format 2-6 associated with the DRX cycle.

Step 202: The terminal performs downlink reception and/or uplink transmission according to the DRX-related configuration information.

In this embodiment of the present application, the terminal obtains DRX-related configuration information, and the DRX-related configuration information includes M pieces of DRX starting offset information. The terminal performs downlink reception and/or uplink transmission according to the DRX related configuration information. The corresponding M DRX durations can be determined through the M DRX start offset information, and then based on the M DRX durations, alignment and matching with the data packet arrival time can be achieved, thereby reducing data transmission delay and terminal function. Consumption.

Optionally, the method in this embodiment of the present application further includes: the terminal starting an associated DRX duration timer based on each of the DRX start offset information.

Optionally, the value ranges corresponding to the M DRX start offsets are the same, and/or the DRX cycles associated with the M DRX start offsets are the same.

It should be noted that the DRX start offset is associated with the DRX cycle, which can be understood as the DRX start offset being the DRX start offset of the DRX cycle. The starting subframe of the DRX cycle or the onduration of the DRX cycle (DRX onduration for short, the same below) can be determined according to the DRX start offset. In addition, according to the value of the DRX cycle, it can be determined that the range of the DRX start offset is (0, DRX cycle size minus 1); therefore, if the DRX cycles associated with the M DRX start offsets are the same, it means The M DRX starting offsets correspond to the same value range.

In the embodiment of this application, M DRX duration (DRX onduration) timers are determined based on M DRX start offset information, that is, M DRX durations. In this way, in one embodiment, when M DRX start offsets correspond to the same DRX cycle, it is possible to have multiple DRX durations corresponding to one DRX cycle, thereby facilitating the implementation of DRX onduration and services in the DRX configuration. Packet arrival times are aligned for matching purposes.

Optionally, the M DRX start offsets correspond to N sets of DRX configurations, or the M DRX start offsets correspond to a set of DRX configurations, 1<N≤M.

Among them, a set of DRX configurations that can include DRX-related parameters has been described accordingly in the above description and will not be described again this time.

It should be noted that when the M DRX starting offsets correspond to N sets of DRX configurations, In this case, the DRX start offset (drx-StartOffset) is used to determine the DRX cycle or the starting subframe of the DRX onduration (note, the DRX cycle is the same as the starting subframe of the DRX onduration). For example, N=M, M DRX start offsets correspond to M sets of DRX configurations, then there is only one DRX start offset for one set of DRX configurations, that is to say, there is only this DRX start offset in one DRX cycle. A DRX onduration determined by the quantity; when the M DRX start offsets correspond to a set of DRX configurations, the DRX start offset is used to determine the start subframe of the DRX onduration. In addition, a DRX cycle can be associated with M DRX start offsets. That is to say, there can be DRX onduration determined by M DRX start offsets in a DRX cycle. Therefore, in both cases, the purpose of aligning and matching DRX onduration and service packet arrival time can be achieved.

Optionally, in the case where the M DRX starting offsets correspond to N sets of DRX configurations, the N sets of DRX configurations have the same or common at least one of the following:

DRX cycle;

DRX duration timer;

DRX inactive timer;

DRX retransmission related timer;

DRX slot offset, which is the offset between the start moment of the DRX duration timer and the starting position of the starting subframe of the DRX cycle;

Related configuration of energy-saving downlink control information DCI, which is used to indicate whether to perform PDCCH monitoring.

Here, the above-mentioned sharing and the same meaning are not the same. The above-mentioned sharing of at least one of the following can be understood as having only one set of the following at least one, and the above-mentioned having the same at least one of the following is understood as the same value of at least one of the following.

For example, having the same timer configuration value and sharing the same set of timers have different meanings. The former corresponds to multiple timers with the same value, and the latter corresponds to a single timer.

In the embodiment of the present application, when the M DRX starting offsets correspond to N sets of DRX configurations, by agreeing that the N sets of DRX configurations have the same or shared DRX related parameters (for example, have the same DRX cycle), This can be achieved without introducing a DRX cycle combination (DRX cycle combination refers to, for example, the DRX formed by three DRX cycles of 16ms, 17ms, and 17ms). Periodic combination to achieve the purpose of aligning and matching its business data packet arrival time), DRX onduration and data packet arrival time, thereby reducing data transmission delay and terminal power consumption.

Optionally, in the case where the M DRX starting offsets correspond to N sets of DRX configurations, the N sets of DRX configurations have at least one of the following that is not shared or the same:

DRX duration timer;

DRX inactive timer;

DRX retransmission related timer.

In the embodiment of the present application, having at least one of the following items that are not shared can be understood as N sets of DRX configurations. Each set of DRX configurations has at least one of the following items. Having at least one of the following items that are different can be understood as having different values. The above-mentioned non-sharing can also be described as independent. For example, not sharing the DRX duration timer means that each of the N sets of DRX configurations is configured with a DRX duration timer. For another example, having different DRX duration timers means that the value of the DRX duration timer in each set of N sets of DRX configurations may be different.

In the embodiment of this application, N sets of DRX configurations have shared or non-shared DRX parameters. The configuration rules when configuring the specific Radio Resource Control (Radio Resource Control, RRC) Information Element (IE) are:

Set a certain set of DRX configurations among the N sets of DRX configurations as the main DRX configuration. For example, specify the DRX configuration ID=0 as the main DRX configuration. The other DRX configurations are secondary DRX configurations. The DRX parameters shared between them do not need to be configured additionally in the secondary DRX configuration, but only the shared DRX parameters need to be configured in the primary DRX configuration. The DRX parameters that are not shared between them need to be included in their respective DRX configurations.

Optionally, the value of the DRX cycle includes at least one of the following:

25ms; 33ms; 34ms; 44ms; 45ms; 50ms; 100ms.

Optionally, in the embodiment of the present application, the DRX duration periods associated with the M DRX start offsets do not overlap with each other, or the DRX duration periods associated with the M DRX start offsets can overlap each other.

It should be noted that the DRX duration periods associated with the M DRX start offsets do not overlap each other may mean that at least two of the M DRX start offsets are associated with The DRX duration periods do not overlap each other, specifically, the at least two DRX starting offsets The DRX duration periods associated with the quantities do not overlap each other, which means that the difference between at least two DRX start offsets is greater than or equal to the maximum DRX duration length among the DRX durations associated with the two.

Optionally, the values of the M DRX starting offsets are related to the service cycle or the time interval between adjacent service packets.

In one embodiment, two DRX start offsets with adjacent values among the M DRX start offsets need to satisfy that the difference between the two is and or L refers to the business cycle value. The value of Δ can be 0, 1 or 2. For example, if the XR video service cycle value is 16.67ms and Δ=1, then the two DRX start offsets with adjacent values among the M DRX start offsets need to satisfy that the difference between the two is 16± 1 or 17±1, that is to say, the starting offsets of two DRXs with adjacent values can be 15, 16, 17, 18.

In the embodiment of the present application, by configuring the DRX duration periods associated with the M DRX start offsets not to overlap with each other, problems such as reduced PDCCH monitoring efficiency due to mutual overlap can be avoided, ensuring maximum effective PDCCH monitoring. duration.

In the embodiment of the present application, the length of the DRX duration period is determined by the DRX duration timer, which will not be described again.

Optionally, the method in the embodiment of this application also includes:

In the case where the DRX duration periods associated with the M DRX start offsets overlap, the DRX duration timer is restarted at the overlapping position.

It should be noted that restarting the DRX duration timer means that the terminal side still maintains the existing started DRX duration timer without additionally starting a new DRX duration timer.

For example, if two DRX duration periods associated with two DRX start offsets overlap each other, at the overlap point, the terminal restarts the DRX duration timer associated with the former DRX start offset and restarts The duration of the DRX duration timer is determined based on the duration of the latter DRX duration timer (associated with the DRX start offset).

Optionally, the DRX-related configuration information also includes DRX timer information associated with each of the M DRX start offsets;

Wherein, the DRX timer includes: at least one of a DRX duration timer and a DRX inactivation timer.

Optionally, the DRX timer values associated with the M DRX start offsets may be the same or different.

For example, if the values of the DRX timers associated with the M DRX start offsets are the same, it is convenient to manage the DRX timer. The network can configure the same DRX timer value for the M DRX start offsets. Just value. For another example, if the M DRX start offsets are associated with different DRX timer values, the network can configure different DRX timer values for the M DRX start offsets, which is more helpful. flexibility in network configuration.

Optionally, the values of the M DRX start offsets are related to service packet arrival timing patterns.

Optionally, at least one of the DRX cycle associated with the M DRX start offsets and the value of M is related to service cycle information; wherein the service cycle information includes: video frame rate.

In one embodiment, the frame rate of the XR video service package is 60 frames per second (Frames Per Second, FPS), and the corresponding service package period is 16.67ms. The service packet arrival timing pattern refers to that three video service packets (referring to video frames) will arrive every 50ms. The adjacent time intervals of these three frames are: 16ms, 17ms, and 17ms respectively. Therefore, 16ms, 17ms, and 17ms form a service packet arrival timing pattern. Therefore, when configuring the values of M DRX start offsets, the network can configure M = 3 DRX start offsets according to the service packet arrival timing pattern, and configure appropriate DRX start offsets respectively. value, and the three DRX start offsets correspond to or are associated with the same DRX cycle, for example, DRX cycle = 50ms, thereby achieving matching and correspondence between DRX onduration and service packet arrival time, and achieving the effect of reducing data packet transmission delay .

Optionally, in the case where the DRX cycle associated with the M DRX start offsets is related to the video frame rate, the value of the DRX cycle is less than or equal to:

Simplification to the numerator obtained by reciprocally prime the numerator and the denominator.

In the embodiment of this application, The physical meaning represented is the average time interval between two adjacent data packets, in milliseconds. Two integers are relatively prime if their common divisor is only 1. It should be noted that the above numerator and denominator are integers.

Optionally, in the case where the value of M is related to the video frame rate, the value of M is less than or equal to:

Simplification to the denominator obtained by reciprocally prime the numerator and the denominator.

For example, if the frame rate is 60FPS, then simplify (1000/60) to the mutually prime numerator and denominator to get (50/3), then the denominator is equal to 50, that is, the value of the DRX cycle is equal to 50ms, and the numerator is equal to 3, that is, M=3 , that is, 3 DRX starting offsets.

Optionally, the M DRX starting offset information is obtained through at least one of the following:

DRX configuration list; wherein, the DRX configuration list includes N sets of DRX configuration information corresponding to M DRX starting offsets. For example, the DRX configuration list includes the index of N sets of DRX configurations corresponding to M DRX starting offsets. value;

DRX start offset list; wherein, the DRX start offset list contains the M DRX start offset information, optionally, the DRX start offset list is included in 1 set DRX is being configured.

The above method of obtaining M DRX start offset information through the DRX configuration list is a method of implicitly obtaining M DRX start offsets through the corresponding relationship between N sets of DRX configurations and M DRX start offsets.

In the above method of obtaining the DRX start offset through the DRX start offset list, you only need to add the DRX start offset list, which can effectively save signaling overhead.

In a specific embodiment of this application, the configured DRX configuration list contains M sets of DRX configurations, as shown below, and the following four parameters are added, among which, drx-ConfigToAddModList represents the newly added DRX configuration list parameter, drx-ConfigToReleaseList and The new DRX configuration list corresponds to the release of relevant parameters of the DRX configuration list. DRX-configID represents the index of the DRX configuration, and DRX-configId represents the specific index value and value range of the DRX configuration.

In a specific embodiment of the present application, the new DRX cycle values are: 25ms, 34ms, 50ms, and 100ms. The details are as follows:

In a specific embodiment of the present application, a new drx-startoffset list is added, which contains M drx-startoffset values. Optionally, place the newly added drx-startoffset list in a specific DRX configuration IE, as shown in method 1:

Method 1: drx-startoffsetList SEQUENCE(SIZE(1..M))OF drx-LongCycleStartOffset

It should be noted that after determining the long-cycle DRX cycle length and the drx-startoffset value range corresponding to the DRX cycle length according to the parameter drx-LongCycleStartOffset, the specific drx-startoffset value is based on the M drx-startoffsets in the drx-startoffsetlist Determine the value.

Another way to add a new drx-startoffset list is as follows. Add the following content under the corresponding new DRX cycle value:

Here, the terminal reports the first capability information so that the network side device configures the M DRX starting offsets for the terminal if the terminal supports configuring the M DRX starting offsets.

Optionally, the terminal obtains discontinuous reception DRX related configuration information, including:

If the terminal supports configuring the M DRX start offsets, obtain the M DRX start offset information.

Optionally, the method in the embodiment of this application also includes:

In the case where the M DRX starting offsets correspond to N sets of DRX configurations and one cell is associated with or applies at least two sets of DRX configurations among the N sets of DRX configurations, the N sets are triggered and/or run at the same time. One of the first DRX timers respectively corresponding to the DRX configuration; wherein the first DRX timer includes: at least one of a DRX duration timer and a DRX inactivation timer.

The above-mentioned cell can be any serving cell.

In this embodiment of the present application, the DRX configuration includes a DRX timer configuration, and only one DRX timer of the same type can run and/or trigger at the same time.

Here, DRX timers of the same type (referring to timers with the same name) can only be triggered once at the same time. (that is, two DRX timers of the same type cannot be triggered at the same time. For example, triggering two DRX onduration timers at the same time is not allowed). That is to say, the MAC layer only maintains the operation of a set of DRX timers. If the same type of DRX timer is configured with multiple different values, just run according to the largest DRX timer value.

In one embodiment, when a serving cell is configured with two sets of DRX configurations (for example, DRX configuration 1 and DRX configuration 2), since different DRX configurations contain respective DRX timer configurations, on the serving cell , when the terminal receives the newly transmitted PDCCH, it does not expect to trigger the respective drx-inactivitytimers of DRX configuration 1 and DRX configuration 2 at the same time, but only triggers one drx-inactivitytimer, and the length of the drx-inactivitytimer is DRX configuration 1 and DRX Configure the drx-inactivitytimer length with the largest value among the respective drx-inactivitytimers of 2. The advantage of this is that the MAC layer of the terminal only needs to maintain the operation of one drx-inactivitytimer at all times, instead of maintaining the operation of two drx-inactivitytimers corresponding to two sets of DRX configurations at the same time, thus reducing timer maintenance costs. , reduce overhead.

In a specific embodiment of the present application, the frame rate of the XR service is 120FPS. According to the frame rate, the average time interval between two adjacent data packets is calculated as

According to the arrival time interval of the above data packets, as shown in Figure 3, the network configuration:

(1) M = 3 (equal to the denominator) DRX start offset configurations, the 3 DRX start offsets correspond to the same DRX cycle; and each DRX start offset corresponds to one set of DRX configurations, 3 sets The DRX cycle and other parameters in the DRX configuration are shared or the same to achieve alignment between the DRX onduration and the service package.

(2) Three DRX start offsets correspond to a set of DRX configurations, and the three DRX start offsets correspond to the same DRX cycle.

The DRX period corresponding to 3 DRX starting offsets is 25ms (equal to the numerator);

The network configures three drx-startoffsets (the value range is 0 to DRX cycle size/ms-1) according to the above-mentioned service packet arrival timing pattern (that is, the arrival time interval of data packets), respectively: drx-startoffset1=0 ; drx-startoffset2=8; drx-startoffset3=16; This enables DRX onduration to match the data packet arrival time, reducing data transmission delay and terminal power consumption.

Of course, it should be noted that when the frame rate of the XR service is 120FPS, the three DRX start offset combinations configured by the network do not rule out other possibilities, such as: drx-startoffset1=0; drx-startoffset2=9; drx-startoffset3=17; Another example: drx-startoffset1=0; drx-startoffset2=8; drx-startoffset3=17.

It should be noted that Figure 3 only shows the pattern formed by three DRX initial offsets within one DRX cycle (25ms); subsequent time loops can be carried out according to the pattern in the above figure.

Determine the starting subframe of the DRX onduration of each of the above three DRX starting offsets according to the following formula: DRX cycle=25ms in the above figure, the three drx-startoffset values are 0, 8, and 16 respectively;

[(SFN×10)+subframe number]modulo(drx-LongCycle)=drx-StartOffset, where SFN is the system frame number and subframe number is the number of subframes.

In the embodiment of this application, by configuring multiple DRX start offset (drx-startoffset) information (which can correspond to one set of DRX configurations, or corresponding to N sets of DRX configurations), and agreeing that they correspond to the same or the same DRX cycle, Without introducing different DRX cycle combinations (DRX cycle combination refers to, for example, the DRX cycle combination formed by three DRX cycles of 16ms, 17ms, and 17ms to achieve the arrival time of service data packets), realize DRX onduration and data packet Alignment and matching of arrival times, thereby reducing data transmission delay and terminal power consumption.

In another specific embodiment of the present application, the frame rate of the XR service is 60FPS. According to the frame rate, the average time interval between two adjacent data packets is calculated as

According to the arrival time interval of the above data packets, the network configures 3 (equal to the denominator) DRX start offset corresponding to the same DRX cycle of 50ms (equal to the numerator);

The network configures three drx-startoffsets (the value range is 0~DRX cycle size/ms-1) accordingly according to the above service packet arrival timing pattern (that is, the arrival time interval of data packets) as follows:

Option1: drx-startoffset=0; drx-startoffset=16; drx-startoffset=33;

Option2: drx-startoffset=0; drx-startoffset=17; drx-startoffset=33;

Option3: drx-startoffset=0; drx-startoffset=17; drx-startoffset=34.

In yet another embodiment of the present application, the frame rate of the XR service is 30FPS. According to the frame rate, the average time interval between two adjacent data packets is calculated as

According to the arrival time interval of the above data packets, the network configures 3 (equal to the denominator) DRX start offset corresponding to the same DRX cycle of 100ms (equal to the numerator);

The network configures 3 drx-startoffset accordingly (the value range is 0~DRX cycle size/ms-1) according to the above-mentioned service packet arrival timing pattern (that is, the arrival time interval of data packets):

Option1: drx-startoffset1=0; drx-startoffset2=33; drx-startoffset3=66;

Option2: drx-startoffset1=0; drx-startoffset2=34; drx-startoffset3=67;

Option3: drx-startoffset1=0; drx-startoffset2=33; drx-startoffset3=67.

In another embodiment of the present application, the frame rate of the XR service is 90FPS. According to the frame rate, the average time interval between two adjacent data packets is calculated as

According to the arrival time interval of the above data packets, the network configures 3 (less than the denominator) DRX start offset corresponding to the same DRX cycle of 34ms (less than the numerator);

Option1: drx-startoffset1=0; drx-startoffset2=11; drx-startoffset3=22;

Option2: drx-startoffset1=0; drx-startoffset2=12; drx-startoffset3=23;

Option3: drx-startoffset1=0; drx-startoffset2=11; drx-startoffset3=23;

Since only 3 DRX start offsets smaller than the denominator size are configured, after a period of time because the data packet arrival cannot be completely matched, the data packet and the DRX onduration will be staggered. At this time, the values of the three drx-startoffset can be updated through RRC reconfiguration to realign the two.

Of course, the optimal network configuration method is to configure 9 DRX starting offsets (M=9), and the corresponding DRX cycle is 100ms.

The network configures these 9 drx-startoffsets accordingly (the value range is 0 to DRX cycle size/ms-1) based on the above-mentioned service packet arrival timing pattern (that is, the arrival time interval of data packets). For example, drx-startoffset list is: 0 11 22 33 44 56 67 78 89.

The information transmission method of the embodiment of this application configures different drx-startoffsets for the same DRX cycle (which can correspond to one set of DRX configurations, or to M sets of DRX configurations) to achieve alignment and matching of DRX onduration and data packet arrival time, thereby reducing Data transmission delay and terminal power consumption.
