Technical Field

The application belongs to the technical field of communication, and particularly relates to an information transmission method, an information transmission device and communication equipment.

Background

In an Extended Reality (XR) service model, service packet arrival intervals are equal, and the intervals are smaller floating point numbers (non-positive integers). In addition, XR traffic requires high latency, with an air interface transmission packet latency budget (Packet Delay Budget, PDB) of around 10 ms. To achieve terminal power savings under XR services, the network may be configured with a short discontinuous reception (Discontinuous Reception, DRX) timer, but at the same time needs to ensure a very close fit with the service model to meet the requirements for completing packet transmissions within the PDB. However, currently existing standards cannot be configured to conform to the DRX configuration of the arrival of the traffic packet.

The following description is presented to enable one skilled in the art to better understand the embodiments of the present application.

1. XR traffic.

Extended reality (XR) refers to all real and virtual combined environments and human-machine interactions generated by computer technology and wearable devices. It includes representative forms of augmented Reality (Augmented Reality, AR), mixed Reality (MR), virtual Reality (VR), and the like, as well as interpolation regions therebetween. The level of the virtual world is from a partially sensory input to a fully immersive virtual reality. One key aspect of XR is the expansion of human experience, especially experience related to sense of presence (represented by VR) and cognition learning (represented by AR).

2. Radio resource control (Radio Resource Control, RRC) connected discontinuous reception (Discontinuous Reception, DRX).

One basic DRX cycle (DRX cycle) consists of "On Duration" and "Opportunity for DRX": during the "On Duration" time, the UE listens to the PDCCH; during the "Opportunity for DRX" time, the UE does not monitor the PDCCH to save power consumption.

In addition, the network configures a DRX inactivity timer (DRX inactivity timer), and if a newly transmitted PDCCH is received within an association, DRX inactivity timer is started or restarted to extend the duration of the UE listening to the PDCCH.

3. A DRX timer.

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

The DRX duration timer (DRX-onduration timer) is started only once per DRX cycle, and the duration formed by DRX-onduration timer is located at the start of the DRX cycle.

A DRX inactivity Timer (DRX-inactivity Timer) that starts or restarts the first symbol after the reception of the new PDCCH ends. When the corresponding MAC receives the DRX Command or Long DRX Command MAC CE, stopping the Timer.

The DRX slot offset is used to determine the delay before DRX-onduration timer is started.

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

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

step 201: the terminal acquires discontinuous reception DRX related configuration information, wherein the DRX related configuration information comprises M pieces of DRX initial offset information, and M is a positive integer greater than 1.

The above DRX start offset information is used to determine a start subframe of a DRX duration (duration) or a start subframe of a DRX cycle (cycle). Alternatively, the DRX start offset information may be used to determine the start subframe of the DRX duration as the DRX start offset corresponds to or is associated with or determines the DRX duration.

Optionally, the M DRX start offset information corresponds to the same DRX cycle.

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

Optionally, the M DRX start offsets include one DRX start offset given in an existing (legacy) set of DRX configurations, and an additional newly added (additional or enhanced) M-1 DRX start offsets. That is, M refers to the number of DRX start offsets obtained in total by the terminal side. For example, m=2, where one DRX start offset is given in the existing (legacy) set of DRX configurations. While another DRX start offset is given by other configuration parameters.

Optionally, the M DRX start 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 configurations includes the following DRX parameters:

a DRX cycle;

a DRX duration timer (DRX onduration timer);

a DRX inactivity timer (DRX inactivity timer);

DRX retransmission related timer;

a DRX slot offset (DRX-SlotOffset), which is an offset (the delay before starting the DRX-onduration timer) between the starting time of the DRX duration timer and the starting position of the starting subframe of the DRX cycle;

And (3) relevant configuration of energy-saving Downlink Control Information (DCI) used for indicating whether to monitor the PDCCH, wherein the energy-saving DCI can be specifically DCI scrambled by cyclic redundancy check (Cyclic redundancy check, CRC) through power save-Radio Network Temporary Identifier (RNTI). The above-described related configuration may also be described as a DCP related configuration, where DCP refers to DCI formats 2-6 associated with DRX periods.

Step 202: and the terminal performs downlink receiving and/or uplink sending according to the DRX related configuration information.

In the embodiment of the application, a terminal acquires DRX related configuration information, wherein the DRX related configuration information comprises M pieces of DRX initial offset information. And the terminal performs downlink receiving and/or uplink sending according to the DRX related configuration information. Corresponding M DRX duration times can be determined through the M DRX initial offset information, and then alignment and matching with the arrival time of the data packet can be achieved based on the M DRX duration times, so that data transmission delay and terminal power consumption can be reduced.

Optionally, the method of the embodiment of the present application further includes: and the terminal starts an associated DRX duration timer according to each DRX initial offset information.

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

It should be noted that, the DRX start offset is associated with the DRX cycle, and may be understood as the DRX start offset of the DRX cycle. The DRX cycle or a start subframe of an onduration of the DRX cycle (hereinafter abbreviated DRX onduration) may be determined according to the DRX start offset. In addition, the range of the DRX initial offset can be determined to be (0) according to the value of the DRX cycle, and the DRX cycle is reduced by 1); therefore, if the DRX periods associated with the M DRX start offsets are the same, it is indicated that the value ranges corresponding to the M DRX start offsets are the same.

In the embodiment of the present application, M DRX duration (DRX duration) timers, that is, M DRX durations, are determined according to M DRX start offset information. In this way, in one embodiment, when the M DRX start offsets correspond to the same DRX cycle, a plurality of DRX durations may be implemented in one DRX cycle, so as to facilitate the purpose of alignment and matching between the DRX duration and the service packet arrival time in the DRX configuration.

Optionally, the M DRX start offsets correspond to N sets of DRX configurations, or the M DRX start offsets correspond to one set of DRX configurations, where N is greater than 1 and less than or equal to M.

The set of DRX configuration may include DRX related parameters that have been described in the foregoing description, which is not repeated here.

Note that, in the case where the M DRX start offsets correspond to N sets of DRX configurations, a DRX start offset (DRX-StartOffset) is used to determine a DRX cycle or a starting subframe of a DRX onduration (note that the DRX cycle is the same as the starting subframe of the DRX onduration). For example, n=m, where M DRX start offsets correspond to M sets of DRX configurations, there is only one DRX start offset for a set of DRX configurations, that is, only one DRX onduration determined by the DRX start offset in one DRX cycle; and in the case that the M DRX initial offsets correspond to one set of DRX configuration, the DRX initial offset is used for determining a starting subframe of the DRX duration. Furthermore, one DRX cycle may be associated with M DRX start offsets, that is, there may be a DRX duration determined by the M DRX start offsets within one DRX cycle. Therefore, the aim of alignment and matching of the DRX duration and the arrival time of the service packet can be achieved in both cases.

Optionally, in a case that the M DRX start offsets correspond to N sets of DRX configurations, the N sets of DRX configurations have at least one of the following that are the same or common:

a DRX cycle;

a DRX duration timer;

a DRX inactivity timer;

DRX retransmission related timer;

a DRX time slot offset, which is an offset between a starting time of a DRX duration timer and a starting position of a starting subframe of a DRX period;

and (3) relevant configuration of energy-saving Downlink Control Information (DCI) for indicating whether PDCCH monitoring is performed or not.

Here, the above-mentioned common and the same meaning are not the same, and at least one of the following common may be understood as only one set of at least one of the following, and the at least one of the following may be understood as the same value as the at least one of the following.

For example, the same set of timers is shared by the same timer configuration values, and the meanings of the same set of timers are different, wherein the same set of timers correspond to a plurality of timers with the same values, and the same set of timers correspond to a single timer.

In the embodiment of the application, when the M DRX start offsets correspond to N sets of DRX configurations, the N sets of DRX configurations are defined to have the same or common DRX related parameters (for example, have the same DRX cycle), so that the alignment and matching purposes of the DRX duration and the packet arrival time can be achieved without introducing a DRX cycle combination (the DRX cycle combination refers to, for example, a DRX cycle combination formed by three DRX cycles of 16ms,17ms, and 17ms to achieve the service packet arrival time), thereby reducing the data transmission delay and the terminal power consumption.

Optionally, in a case where the M DRX start offsets correspond to N sets of DRX configurations, the N sets of DRX configurations have at least one of the following that are not common or different:

a DRX duration timer;

a DRX inactivity timer;

DRX retransmission related timer.

In the embodiment of the application, at least one of the following items which are not shared is understood to be at least one of the following items of each set of N sets of DRX configuration, and at least one of the following items which are different is understood to be different in value. The above-mentioned non-commonalities may also be described as being independent of each other. For example, not sharing a DRX duration timer refers to each of the N sets of DRX configurations being 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 of the N sets of DRX configurations may be different.

In the embodiment of the present application, the N sets of DRX configurations have common or non-common DRX parameters, and the configuration rules when the specific radio resource control (Radio Resource Control, RRC) information element (Information Element, IE) is configured are:

a certain set of the N sets of DRX configurations is set as a primary DRX configuration, for example, a primary DRX configuration specifying DRX configuration id=0. While the other DRX configurations are secondary DRX configurations. The DRX parameters shared between them need not be additionally configured in the secondary DRX configuration, but only the shared DRX parameters need to be configured in the primary DRX configuration. Whereas DRX parameters that are not shared between them need to be individually included in the respective DRX configurations.

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

25ms；33ms；34ms；44ms；45ms；50ms；100ms。

optionally, in the embodiment of the present application, DRX duration periods associated with the M DRX start offsets do not overlap each other, or 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 with each other may mean that the DRX duration periods associated with at least two DRX start offsets in the M DRX start offsets do not overlap with each other, and specifically, the DRX duration periods associated with the at least two DRX start offsets do not overlap with each other means that a difference value between the at least two DRX start offsets satisfies a maximum (maximum) DRX duration length of the DRX durations (durations) associated with the at least two DRX start offsets.

Optionally, the values of the M DRX start offsets relate to a service period or a time interval between adjacent service packets.

In one embodiment, two DRX start offsets of the M DRX start offsets that are adjacent to each other need to be different from each otherL refers to the service period value. The value of delta can be 0,1 or 2. For example, when the XR video service period is 16.67ms and Δ=1, two DRX start offsets of the M DRX start offsets that are adjacent to each other need to satisfy the difference between them as 16±1 or 17±1, that is, two DRX start offsets that are adjacent to each other may be 15,16,17,18.

In the embodiment of the application, the DRX duration time periods associated with the M DRX initial offset values are configured not to overlap each other, so that the problems of PDCCH monitoring efficiency reduction and the like caused by overlapping each other can be avoided, and the maximum effective PDCCH monitoring duration time is ensured.

In the embodiment of the present application, the duration of the DRX duration period is determined by the DRX duration timer, which is not described in detail later.

Optionally, the method of the embodiment of the present application further includes:

and restarting the DRX duration timer at the overlapped position under the condition that the DRX duration time periods associated with the M DRX initial offsets are overlapped.

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

For example, 2 DRX duration periods respectively associated with 2 DRX start offsets overlap each other, then at the overlap, the terminal restarts the DRX duration timer associated with the former DRX start offset, and the duration of the restarted DRX duration timer is determined according to the DRX duration timer duration (associated with the DRX start offset) of the latter.

Optionally, the DRX-related configuration information further 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 inactivity timer.

Optionally, the values of the DRX timers 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, the DRX timers are convenient to be managed, and the network may configure the values of the same DRX timer for the M DRX start offsets. For another example, if the values of the DRX timers associated with the M DRX start offsets are different, the network may configure the values of the different DRX timers for the M DRX start offsets, which is more conducive to flexibility of network configuration.

Optionally, the values of the M DRX start offsets are related to a traffic packet arrival timing pattern.

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

In one embodiment, the frame rate of the XR video service packets is 60FPS, with a corresponding service packet period of 16.67ms. The service packet arrival timing pattern refers to that every 50ms, 3 video service packets (referred to as video frames) will arrive, and the adjacent time intervals of the 3 frames are respectively: 16ms,17 ms. Thus, 16ms,17ms form a traffic packet arrival timing pattern. Therefore, when configuring the values of M DRX starting offsets, the network may configure m=3 DRX starting offsets according to the service packet arrival timing pattern, and configure appropriate DRX starting offset values respectively, where the 3 DRX starting offsets correspond or are associated with the same DRX cycle, for example, DRX cycle=50 ms, so as to implement matching and correspondence between DRX onduration and service packet arrival time, and achieve an effect of reducing the data packet transmission delay.

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

simplifying and simplifyingTo the molecular of the molecular denominator.

In an embodiment of the present application,the physical meaning represented is the average time interval between two adjacent packets in milliseconds. The mutual prime of two integers means that the common divisor is only 1. The numerator and denominator are integers.

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

simplifying and simplifyingTo the denominator obtained by the mutual quality of the denominator.

For example, the frame rate is 60FPS, the frame rate is simplified (1000/60) to the numerator denominator, and (50/3) is obtained, and 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 start offsets.

Optionally, the M DRX start offset information is obtained by at least one of:

a DRX configuration list; the DRX configuration list comprises N sets of DRX configuration information corresponding to M DRX initial offset values, for example, the DRX configuration list comprises index values of N sets of DRX configuration corresponding to the M DRX initial offset values;

A DRX start offset list; the DRX start offset list includes the M DRX start offset information, and optionally, the DRX start offset list is included in 1 set of DRX configuration.

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

In the above manner of obtaining the DRX starting offset through the DRX starting offset list, only the DRX starting offset list needs to be added, so that signaling overhead can be effectively saved.

In a specific embodiment of the present application, the configured DRX configuration list includes M sets of DRX configurations, as shown below, and the following four parameters are newly added, where DRX-configtoadmodlist represents a newly added DRX configuration list parameter, DRX-configtorelealist corresponds to a newly added DRX configuration list, DRX-configID represents an index of the DRX configuration, and DRX-configID represents a specific index value and a value range of the DRX configuration.

In one embodiment of the present application, the new DRX cycle is valued: 25ms,34ms,50ms,100ms. The method is specifically as follows:

In one embodiment of the present application, the new drx-startoffset list includes M drx-startoffset values. Optionally, the newly added DRX-startoffset list is placed in a specific DRX configuration IE, as shown in mode one:

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

It should be noted that, after determining the DRX cycle length of the long cycle and the DRX-startoffset value range corresponding to the DRX cycle length according to the parameter DRX-longcyclstartoffset, the specific DRX-startoffset value is determined according to the M DRX-startoffset values in the DRX-startstartsetlist.

Another way to add the DRX-startoffset list is as follows, adding the following under the DRX cycle value corresponding to the new addition:

mode two: ms25 SEQUENCE (SIZE (1..M)) OF INTEGER (0..24),

mode two: ms34 SEQUENCE (SIZE (1..M)) OF INTEGER (0..33),

mode two: ms50 SEQUENCE (SIZE (1..M)) OF INTEGER (0..49),

mode two: ms100 SEQUENCE (SIZE (1..M)) OF INTEGER (0..99).

In the embodiment of the application, a MAC-cell group configuration information element (MAC-CellGroupConfig information element) is used for configuring the MAC parameters of one cell group, including DRX. MAC-CellGroupConfig information element is specifically shown below:

optionally, the terminal performs downlink receiving and/or uplink sending according to the DRX related configuration information, including:

mobility measurement based on a channel state information reference signal, CSI-RS;

reporting a CSI related measurement item, wherein the CSI related measurement item comprises: L1-RSRP, of course, the CSI-related measurement term may also include other measurement terms other than L1-RSRP;

measurement based on CSI reporting;

interference measurement based on CSI-RS.

The downlink reception and/or uplink transmission may be specifically performed in the DRX duration corresponding to the DRX start offset, which may be determined based on the UE implementation, and is not limited herein.

In an embodiment, the M DRX start offsets are associated with the same DRX cycle, so that the measurement and/or reporting is performed in any DRX duration period corresponding to the M DRX start offsets, which can avoid unnecessary power consumption overhead.

Optionally, before the terminal obtains the DRX related configuration information, the method further includes:

And the terminal reports first capability information, wherein the first capability information is used for indicating whether the terminal supports configuration of the M DRX initial offset.

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

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

and under the condition that the terminal supports configuration of the M DRX initial offset, acquiring the M DRX initial offset information.

triggering and/or running one of the first DRX timers corresponding to the N sets of DRX configurations at the same time under the condition that the M DRX initial offset corresponds to the N sets of DRX configurations and one cell associates or applies at least two sets of DRX configurations in the N sets of DRX configurations; wherein the first DRX timer includes: at least one of a DRX duration timer and a DRX inactivity timer.

The one cell may be any one of the serving cells.

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

Here, the same type of DRX timer (referred to as the same name of timer) can only be triggered one at a time (i.e., it is not allowed to trigger two DRX timers of the same type at the same time, e.g., trigger two DRX onduration timer at the same time). That is, the MAC layer maintains operation of only one set of DRX timers. If the same type of DRX timer is configured with multiple different values, it is sufficient to operate with the largest DRX timer value.

In one embodiment, in the case that one serving cell is configured with two sets of DRX configurations (for example, DRX configuration 1 and DRX configuration 2), since different DRX configurations include respective DRX timer configurations, on the serving cell, when the terminal receives a new PDCCH, it is not expected that the terminal triggers respective DRX-inactivity timers of DRX configuration 1 and DRX configuration 2 at the same time, but only one DRX-inactivity timer is triggered, and the length of the DRX-inactivity timer is the DRX-inactivity timer length with the largest value in the DRX-inactivity timers of DRX configuration 1 and DRX configuration 2. The MAC layer of the terminal only needs to maintain the operation of one DRX-inactytimer all the time, and does not need to maintain the operation of two DRX-inactytimers corresponding to two sets of DRX configuration at the same time, so that the maintenance cost of the timer can be reduced, and the cost is reduced.

In one embodiment of the present application, the frame rate of the XR service is 120FPS, and the average time interval between two adjacent data packets is converted according to the frame rate to be

(2) The 3 DRX initial offsets correspond to a set of DRX configuration, and the DRX periods corresponding to the 3 DRX initial offsets are the same.

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

the network configures 3 DRX-startoffset (with a value range of 0 to DRX cycle size/ms-1) according to the above-mentioned traffic packet arrival timing pattern (i.e. arrival time interval of the data packet), where: drx-startoffset 1=0; drx-startoffset 2=8; drx-startoffset 3=16; therefore, DRX duration can be matched with the arrival time of the data packet, and the data transmission delay and the terminal power consumption are reduced.

Of course, it should be noted that, when the frame rate of the XR service is 120FPS, the 3 DRX start offset combinations configured by the network do not exclude other possibilities, for example: drx-startoffset 1=0; drx-startoffset 2=9; drx-startoffset 3=17; also for example: drx-startoffset 1=0; drx-startoffset 2=8; drx-startoffset 3=17.

It should be noted that, in fig. 3, only a pattern formed by 3 DRX start offsets within one DRX cycle (25 ms) is shown; and performing time circulation according to the pattern.

Determining the starting subframe of the DRX duration of each of the 3 DRX starting offsets according to the following formula: DRX cycle=25 ms in the upper graph, and the three DRX-startoffset values are 0,8,16 respectively;

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

In the embodiment of the application, by configuring a plurality of DRX start offset (DRX-startoffset) information (which can correspond to one set of DRX configuration or N sets of DRX configuration), and agreeing that the DRX start offset corresponds to the same or the same DRX period, under the condition that different DRX period combinations (DRX period combinations refer to DRX period combinations formed by, for example, 16ms,17ms and 17ms, the service data packet arrival time of the DRX period is realized), the alignment and the matching of the DRX duration and the data packet arrival time are realized, thereby reducing the data transmission delay and the terminal power consumption.

In yet another embodiment of the present application, the XR service has a frame rate of 60FPS, and the average time interval between two adjacent data packets is scaled according to the frame rate to be

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

the network configures 3 DRX-startoffset (with a value range of 0 to DRX cycle size/ms-1) according to the above-mentioned traffic packet arrival timing pattern (i.e. arrival time interval of the data packet), where:

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 XR service has a frame rate of 30FPS, and the average time interval between two adjacent data packets is scaled according to the frame rate to be

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

the network configures 3 DRX-startoffsets (with a value ranging from 0 to DRX cycle size/ms-1) according to the traffic packet arrival time sequence pattern (i.e. the arrival time interval of the data packet)

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, and the average time interval between two adjacent data packets is converted according to the frame rate to be

According to the arrival time interval of the data packet, the network configures the same DRX cycle corresponding to 3 (smaller than denominator) DRX initial offset to 34ms (smaller than 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, the packet is staggered from the DRX duration over time because it cannot be completely matched to the packet arrival. At this time, the values of 3 drx-startoffset can be updated by RRC reconfiguration, so that the two are realigned.

Of course, the configuration method of the network optimization is to configure 9 DRX start offsets (m=9), and the corresponding DRX cycle is 100ms.

The network configures the 9 DRX-startoffset (with a value ranging from 0 to DRX cycle size/ms-1) according to the above-mentioned traffic packet arrival timing pattern (i.e. the arrival time interval of the data packet). For example, drx-startoffset list is: 0 11 22 33 44 56 67 78 89.

According to the information transmission method provided by the embodiment of the application, different DRX-startoffset (which can correspond to one set of DRX configuration or M sets of DRX configuration) is configured for the same DRX period, so that alignment and matching of DRX duration and data packet arrival time are realized, and the data transmission delay and terminal power consumption are reduced.
