Referring to fig. 1, fig. 1 is a block diagram of a network system to which an embodiment of the present application is applicable, as shown in fig. 1, including a User terminal 11 and a base station 12, where the User terminal 11 may be a User Equipment (UE), for example: the terminal side devices may be mobile phones, tablet computers (Tablet Personal Computer), laptop computers (Laptop computers), personal digital assistants (personal digital assistant, PDA for short), mobile internet devices (Mobile Internet Device, MID) or Wearable devices (webable devices), etc., and it should be noted that the specific type of the user terminal 11 is not limited in the embodiments of the present application.

Firstly, based on the technical scheme provided by the application, partial technical terms possibly related to the technical scheme are introduced.

1. Uplink dynamic scheduling

The terminal sends a scheduling request (Scheduling Request, SR) or a buffer status report (Buffer Status Report, BSR) to the base station to request uplink transmission resources, the base station sends uplink scheduling downlink control information (Downlink Control Information, DCI) to allocate resources to the terminal, and the terminal transmits a physical uplink shared channel (Physical Uplink Shared Channel, PUSCH) on the uplink resources allocated by the uplink scheduling DCI. The uplink scheduling DCI includes a time domain resource, a frequency domain resource, a modulation coding scheme (Modulation and coding scheme, MCS) and the like of a PUSCH allocated to the terminal.

2. Fetch request (Scheduling Request, SR)

When there is an uplink data to be transmitted by a User Equipment (UE), but there is no uplink resource, an SR is transmitted on a physical layer channel physical uplink control channel (Physical Uplink Controlled Channel, PUCCH) by transmitting an SR request to apply for uplink scheduling to the network.

In the medium access control (Medium Access Control, MAC) configuration, logical channels may each be associated with one SR configuration. The different SR configurations are distinguished by a scheduling request identity (schedulingRequestId), which also associates a scheduling request prohibit timer (SR-prohibit timer) and a maximum number of SR transmissions (SR-TransMax) at the MAC level. The specific SR corresponds to a physical layer resource configuration, and in PUCCH-Config, the configuration is configured for each uplink bandwidth Part (BWP), and the schedulingrequestresource id is used to distinguish between different resource configurations, where the schedulingRequestID is associated. The method also comprises the configuration of the SR sending time point and the corresponding PUCCH Resource configuration.

To summarize, as shown in fig. 2, the association relationship of the Logical channels (Logical channels) corresponds to at most one SchedulingRequestID, and a plurality of Logical channels may share one SchedulingRequestID, and for the Logical Channel 4 in the drawing, since the SR is not configured, if there is data transmission on the Logical Channel, uplink scheduling can only be obtained through a random access procedure.

The periodic and offset in schedulingRequestResourceConfig determines the transmit time position of the SR, noting that its minimum period is 2 symbols.

In the protocol description, there are concepts of Positive SR and Negative SR, the UE does not always have a need to send an SR request, for Positive SR, i.e. UE has an SR request to send, the physical layer is required to send SR/PUCCH, and for UE without an SR request to send, at the point in time of SR resource, the SR is Negative SR.

3. Augmented Reality (XR) business feature:

XR is one of the most important types of 5G media applications, and is represented by three types of augmented reality (Augmented reality, AR), mixed Reality (MR), virtual Reality (VR), and a real-Virtual combined environment and related man-machine interaction generated by computer technology and a wearable device. The degree of AR-to-VR virtualization is from weak to strong, i.e., from the actual Augmented Reality (AR) of the sensor portion perceived input to the presence of a fully virtual person (VR), with the visual, auditory, or environmental illusion of the person being presented by the XR device.

According to the study of SA2, SA4 and RAN1 on XR traffic, XR traffic is specifically similar to periodic transmission characteristics, i.e. XR traffic sources will generate corresponding data packets at a refresh rate. For example: a refresh rate of 60 frames (60 FPS) means that 60 data frames are generated per second with a 16.67 millisecond interval between data frames. A refresh rate of 120 frames (120 FPS) means 120 data frames per second are generated, with a time interval of 8.33 milliseconds between data frames.

From the collection of VR traffic data streams by SA4, the packet size and delay jitter (jitter) characteristics of the variable rate video stream can be seen to follow the truncated gaussian distribution.

Based on the above discussion, it can be seen that XR traffic has the following characteristics:

one is a periodic like nature, comprising Uplink (UL), downlink (DL), typical video, audio traffic, arriving at 60 frames per second, i.e. an arrival period of 16.67ms. In particular, for UL traffic, including video, audio streams, UL post, where the period of UL post traffic is more dense, up to 4ms of post packets. In particular, as shown in fig. 3.

And secondly, the data packet size is time-varying. According to current research, the size of the data packet of the XR service follows the Pareto (Pareto) distribution, that is, the size of the data packet of the XR service varies with time.

Third, the multi-stream nature of the packets. For XR traffic, there may be multiple data streams at the same time, e.g., I-frame, P-frame, video stream, audio stream, sense/control, etc. These data streams may be of different levels according to current 5QI QOS requirements. In addition, these data flows are independent from each other according to the 5QI QoS requirement.

4. I/P frame multi-stream traffic:

i-frame (Intra-frame) is Intra-coded, which can characterize a complete picture, and P-frame (Predicted picture) is inter-coded, which only needs to carry different information than the previous frame. Therefore, the I-frame data volume is large, and the reliability requirement is high; the amount of P-frame data is small and reliability is low relative to I-frame requirements. For different coding levels, the service models are classified into a service model based on slice and a service model based on group picture GOP, and a specific coding schematic diagram can be seen in fig. 4. Here, slice is a further segmentation of the frame packet. For a service model based on slice, a data packet of a terminal arriving at the same moment comprises I slice and P slice, wherein the I slice is generally larger than the P slice in data volume; for a group-GOP based traffic model, only I frames or P frames are in the packets of one terminal arriving at the same time, I frames are typically larger than the amount of P frame data.

Based on analysis, the embodiment of the application provides an information transmission method, an information transmission device, terminal equipment and network equipment, which are used for solving the problem that the network equipment cannot judge the time delay perception scheduling priority of a terminal and further cannot realize accurate scheduling for uplink dynamic scheduling.

The method and the device are based on the same application, and because the principles of solving the problems by the method and the device are similar, the implementation of the device and the method can be referred to each other, and the repetition is not repeated.

As shown in fig. 5, an embodiment of the present application provides an information transmission method, which is executed by a terminal device, and includes:

step S501, obtaining first information;

it should be noted that, the first information is used for assisting the network device to determine the scheduling sequence of the terminal device;

step S502, the first information is sent to the network device.

It should be noted that, by sending the first information for assisting the network device to determine the scheduling sequence of the terminal device to the network device, the network device can determine the delay sensing scheduling priority of the terminal, thereby realizing accurate scheduling.

Optionally, the first information in the embodiment of the present application includes at least one of the following:

a11, data packet delay information;

it should be noted that, in this case, an alternative implementation manner of the step S501 is:

Here, the terminal device quantizes the delay experienced by the data packet using a quantization rule, that is, the data packet delay information is a quantized value of the delay experienced by the data packet of the terminal device.

A12, terminal scheduling reference priority information;

wherein the first parameter comprises one of:

a121, consulting a priority critical value set;

it should be noted that, the reference priority threshold set includes a plurality of reference priority thresholds, where the reference priority thresholds are used for determining a terminal scheduling reference priority, for example, the terminal scheduling reference priority is divided into a high priority, a medium priority and a low priority, the reference priority threshold set includes two reference priority thresholds with different sizes, and if the time delay experienced by the data packet is less than the minimum reference priority threshold in the reference priority threshold set, the terminal scheduling reference priority is a low priority; if the time delay of the data packet is between two reference priority critical values in the reference priority critical value set, the terminal scheduling reference priority is a medium priority; if the time delay experienced by the data packet is greater than the largest reference priority threshold in the reference priority threshold set, the terminal schedules the reference priority to be high priority. It should be noted that this is only an example, and does not limit the present application.

A122, a reference priority candidate value set and a reference priority critical value set;

the reference priority candidate value set includes a plurality of reference priority candidate values, the reference priority critical value set includes a plurality of reference priority critical values, and the reference priority critical values and the reference priority candidate values are used together to determine the reference priority of the terminal scheduling. For example, the terminal scheduling reference priority is divided into a first priority, a second priority, a third priority and a fourth priority, wherein the first priority and the second priority are high priority, the third priority and the fourth priority are low priority, the reference priority critical value set comprises a reference priority critical value, if the time delay experienced by the data packet is smaller than the reference priority critical value, one of the third priority and the fourth priority is selected as the terminal scheduling reference priority according to the difference relation between the time delay experienced by the data packet and the reference priority critical value; if the time delay of the data packet is greater than the reference priority critical value, selecting one of the first priority and the second priority as the terminal scheduling reference priority according to the difference relation between the time delay of the data packet and the reference priority critical value. It should be noted that this is only an example, and does not limit the present application.

Alternatively, the first parameter may be configured by the network device, or may be a protocol contract. Specifically, in the case that the first information is configured by the network device, before the determining the terminal scheduling reference priority information according to the delay experienced by the data packet of the terminal device and the first parameter, the method further includes:

the method comprises the steps of receiving a first parameter configured by network equipment through high-layer signaling or downlink control signaling.

it should be noted that, in the embodiment of the present application, the packet type includes one of the following:

I frame；

P frame；

I slice；

P slice。

optionally, the first information is determined based on packet information of the terminal device; it should be noted that, in the embodiment of the present application, the packet information may be at least one of a delay experienced by a packet and a packet type, for example, when the packet information is a delay experienced by a packet, the terminal device may determine that the first information is at least one of a11 and a12 based on the delay experienced by the packet; when the data packet information is of the data packet type, the terminal device determines that the first information is A13 based on the data packet information.

Optionally, the first information is used for requesting uplink transmission resources from the network device, that is, the uplink report of the first information requests uplink transmission resources, and is used for transmitting the data packet corresponding to the first information.

Optionally, a specific implementation manner of step S502 in the embodiment of the present application includes one of the following:

b11, sending a Physical Uplink Shared Channel (PUSCH) to a network device, the first information being carried in the PUSCH;

in this case, the triggering condition of the first information carried by the PUSCH includes:

Here, the usable PUSCH resource is an available PUSCH resource, that is, the usable PUSCH resource is a PUSCH resource for carrying data.

It should be further noted that, the first logical channel or the first logical channel group is associated with a first service, where the first service is a data service corresponding to a data packet associated with the first information. Alternatively, the configuration of the first logical channel or first logical channel group associated with the first service may be agreed upon by the network device configuration or protocol. Preferably, the first service is an XR service.

Optionally, the first information is carried by a media access control layer control element (MAC CE) of PUSCH;

the first bit field includes at least one of:

b111, bit field for carrying logic channel identification;

at this time, the bit field for carrying the logical channel identifier carries the identifier of the logical channel mapped by the data packet associated with the first information.

B112, bit field for carrying logical channel group identifier;

at this time, the bit field for carrying the logical channel group identifier carries an identifier of a logical channel group corresponding to a logical channel mapped by the data packet associated with the first information.

Optionally, the MAC CE may further include:

a bit field carrying an amount of data;

the data amount refers to a size of a buffer occupied by a data packet associated with the first information.

B12 sends a Physical Uplink Control Channel (PUCCH) to the network device, the first information being carried in the PUCCH.

In this case, the PUCCH is transmitted through a first resource, where the first resource is associated with a first service, and the first service is a data service corresponding to a data packet associated with the first information.

Optionally, the first resource is associated with a first service, including:

the first resource is associated with second information;

the second information is associated with a first service;

Alternatively, the configuration of the first resource in association with the first service may be agreed upon by the network device configuration or protocol.

It should also be noted that, before the PUCCH is sent to the network device, the terminal device should also receive configuration information of the first resource sent by the network device;

wherein the configuration information includes at least one of:

a period and an offset of the first resource;

the location of the first resource may be determined by the period and the offset of the first resource, and the terminal device may transmit the PUCCH carrying the first information only at the location indicated by the first resource.

Retransmission time of the first resource;

the terminal device does not transmit the PUCCH carrying the first information before the end of the retransmission time, that is, determines the resource for transmitting the PUCCH next time by the retransmission time.

It should also be noted that the first information is triggered by the PUCCH bearer through the MAC layer of the terminal device.

b121, the MAC layer sends first information to the physical PHY layer, wherein the first information is used for triggering the PHY layer to send PUCCH bearing first information;

and B122, the MAC layer sends a trigger signaling to the PHY layer, wherein the trigger signaling is used for triggering the PHY layer to send PUCCH bearing first information.

It should be noted that, through the transmission of the first information, the network device can learn some information of the data packet level of the terminal, and can more accurately assist in scheduling. For example, the network device can know the data packet delay information corresponding to the delay experienced by the uplink data packet in a certain logic channel of the terminal, comprehensively consider the priority of the logic channel and the reported data packet delay information, and can more reasonably determine the scheduling priority of the terminal device. For example, the terminal equipment only reports delay information of some XR services, and the terminal equipment puts uplink data with the same XR service QoS requirement in the same logic channel and reports data packet delay information corresponding to the delay experienced by the uplink data packet in the logic channel; after receiving the data packet delay information reported by different terminal devices, the network device does not need to transmit the data of the logic channel with higher priority, so that the network device can schedule and sort the terminal devices according to the size of the data packet delay information, schedule the terminal devices with large delay firstly, and schedule the terminal devices with small delay later. For another example, the network device can know the type of the data packet to be transmitted in the uplink of the terminal device, and schedule and sort the data packets according to the importance degrees of the data packets of different types, and preferentially transmit the terminal with the reporting data packet type of Iframe, or configure special transmission parameters (such as more robust MCS level) for the transmission of I slice, so as to realize reasonable resource allocation and improve the system capacity.

The following describes a specific implementation procedure of the embodiment of the present application by taking the first service as an XR service and taking communication between the terminal and the base station as an example.

The method comprises the steps that a terminal reports first information according to a specific application condition, wherein the first information is data packet delay information

Terminal side:

when XR uplink data needs to be transmitted, the terminal maps the XR service data to a first logic channel. The first logical channel is associated with XR service, and the association of the logical channel and the XR service is configured by a base station or agreed by a protocol.

If the MAC layer of the terminal determines that there is an available PUSCH resource, where the available PUSCH resource is a PUSCH resource for carrying data, for example, a PUSCH resource dynamically scheduled by the base station or a PUSCH resource for configuring a Grant (CG) or a PUSCH resource for carrying channel state information (Channel State Information, CSI) that can be multiplexed with data, the terminal may carry data packet delay information through the PUSCH. The PUSCH carries data packet delay information, a first logical channel identifier and a data packet buffer size, including the data packet delay information, the first logical channel identifier and the data packet buffer size carried by the MAC CE in the PUSCH, as shown in fig. 6, where the first logical channel identifier is indicated by a bit field occupied by the logical channel ID, the data packet delay information is indicated by a bit field occupied by the first information, and the data packet buffer size is indicated by a bit field occupied by the data volume.

The reporting of the data packet delay information indicates that uplink resources are requested to the base station and used for transmitting the data packet corresponding to the data packet delay information.

If the MAC layer of the terminal judges that no PUSCH resource is available at the moment, the MAC layer triggers the PHY layer to send PUCCH bearing data packet delay information on the first special PUCCH resource set, the data packet delay information is directly sent to the PHY layer of the terminal by the MAC layer of the terminal through internal signaling and then sent through the PUCCH; the first special PUCCH resource set is configured by the base station, the terminal determines the resource of the PUCCH through the period and the offset configured by the base station, or the base station configures retransmission time, and the terminal does not send the PUCCH carrying the delay information of the data packet before the retransmission time is over, namely, determines the resource of the PUCCH to be sent next through the retransmission time.

It should be noted that, the first dedicated PUCCH resource set is associated with an XR service, for example, the first dedicated PUCCH resource set is associated with a first logical channel (the first logical channel is associated with the XR service), that is, the packet delay information carried by the PUCCH transmitted on the first dedicated PUCCH resource set is the packet delay information of the XR service. And simultaneously, the terminal sends the PUCCH to request uplink resources to the base station to transmit the data packet corresponding to the data packet delay information.

In this application, the packet delay information is obtained by quantizing the delay experienced by the packet using a specific quantization rule. A quantization rule for the delay experienced by data packets for XR traffic is shown in table 1.

A base station side corresponding to the terminal side:

the base station configures XR traffic for the terminal to be associated with the first logical channel, or the base station and the terminal agree that XR traffic is associated with the first logical channel.

The base station configures a first special PUCCH resource set for reporting the data packet delay information for the terminal, and the base station comprises a period and an offset or retransmission time of the first special PUCCH resource set for reporting the data packet delay information for the terminal.

Optionally, the base station receives a PUSCH on a PUSCH resource, where the PUSCH carries the data packet delay information, the first logical channel identifier, and the data packet buffer size, and includes carrying the data packet delay information, the first logical channel identifier, and the data packet buffer size by a MAC CE in the PUSCH. The base station can know which logical channel the data packet delay information carried by the PUSCH MAC CE corresponds to and which logical channel data the uplink transmission resource requested by the terminal uses to transmit, i.e. can know that the data packet delay information corresponds to the XR service, and the uplink transmission resource is used to transmit the XR service.

Optionally, the base station receives PUCCHs carrying the data packet delay information of each terminal sent by each terminal on a first dedicated PUCCH resource set configured for all terminals, and learns the data packet delay information of all terminals. The base station refers to the packet delay information of the terminal to determine the scheduling priority of the terminal, for example, when there is no service with higher priority than the XR service, the network device schedules the terminal with larger packet delay information preferentially.

The application condition enables the base station to acquire the time delay of the uplink data packet in a certain logic channel of the terminal (for example, the terminal can put the uplink data with the same XR service QoS requirement in the same logic channel and report the data packet type of the data packet in the logic channel, thus realizing reporting of the data packet type only for a certain XR service), comprehensively considering the priority of the logic channel and the reported data packet time delay information, and the base station can more reasonably determine the scheduling priority of the terminal. After receiving the delay information of the data packets reported by different terminals, the base station does not need to transmit the data of the logic channel with higher priority (without higher priority than the XR service), and then the base station can schedule and sort the terminals according to the size of the delay experienced by the data packets, wherein the delay experienced by the scheduling is large first and the delay experienced by the scheduling is small later.

Specific application condition II, reporting first information by the terminal, wherein the first information is terminal scheduling reference priority information

Terminal side:

when XR uplink data needs to be transmitted, the terminal maps the XR service data to the first logic channel group. The first logical channel group is associated with XR service, and the association of the logical channel group and the XR service is configured by a base station or agreed by a protocol.

When data in the first logic channel group of the terminal needs to be sent, the terminal determines terminal scheduling reference priority information according to a first parameter, for example, terminal judgment: the time delay of the data packet is smaller than or equal to a first reference priority critical value, and the scheduling reference priority information of the terminal is determined to be low priority; the time delay of the data packet is larger than the first reference priority critical value but smaller than or equal to the second reference priority critical value, and the terminal scheduling reference priority information is determined to be the medium priority; and the time delay of the data packet is larger than a second reference priority critical value, and the terminal scheduling reference priority information is determined to be high priority.

Optionally, the MAC layer of the terminal determines that there is no available PUSCH resource, where the available PUSCH resource is a PUSCH resource for carrying data, and the MAC layer triggers the PHY layer to send PUCCH carrying terminal scheduling reference priority information on the first dedicated PUCCH resource set, where the terminal scheduling reference priority information is directly sent by the MAC layer of the terminal to the PHY layer of the terminal through internal signaling, and then sent through PUCCH. The terminal transmits a PUCCH on a first dedicated PUCCH resource set configured by the base station, where the PUCCH carries terminal scheduling reference priority information, e.g. the terminal scheduling reference priority information is represented by two bits, as shown in table 2.

Table 2b bit map and candidate mapping relation of terminal scheduling reference priority information

The transmission of the PUCCH also means that uplink transmission resources are requested from the base station. The first dedicated PUCCH resource set corresponds to a first logical channel group. The base station can obtain which logical channel group the scheduling reference priority information of the PUCCH bearing terminal corresponds to and which logical channel group data the requested uplink transmission resource is used for transmitting according to the resource position of the PUCCH.

Optionally, the terminal reports the terminal scheduling reference priority information on a PUCCH with PUCCH format 0, and the candidates of the different terminal scheduling reference priority information are distinguished by cyclic shift for generating the transmission sequence. The terminal generates a transmission sequence by using a cyclic shift pre-configured by the base station, and transmits the transmission sequence on the configured PUCCH resource. The combination of different cyclic shift mapping positive SR and different candidates of terminal scheduling reference priority information, and the mapping relation between cyclic shift and candidates of terminal scheduling reference priority information is shown in table 3.

TABLE 3 cyclic shift m _cs Candidate mapping relation with terminal scheduling reference priority information

Optionally, the terminal reports the terminal scheduling reference priority information on the PUCCH with PUCCH format 1, and distinguishes the terminal scheduling reference priority information by different modulation symbols. The terminal modulates the 2-bit bitmap into one modulation symbol through a modulation mode, and maps the modulation symbol to the PUCCH resource for transmission.

Optionally, the terminal reports the terminal scheduling reference priority information on PUCCH of PUCCH format 2, PUCCH format 3 or PUCCH format 4.

Optionally, if the MAC layer of the terminal determines that there are available PUSCH resources, for example, PUSCH resources dynamically scheduled by the base station or Configured Grant (PUSCH resources of CG or PUSCH capable of carrying CSI multiplexed with data), the terminal may schedule the reference priority information by carrying the terminal through the PUSCH. And the terminal sends the PUSCH, and the MAC CE of the PUSCH carries the terminal scheduling reference priority information and the data volume information corresponding to the data packet related to the XR service contained in the first logic channel group. The MAC CE comprises a bit field for bearing the ID of the logical channel group, a bit field for bearing the scheduling reference priority information of the terminal and a bit field for bearing the data volume.

Optionally, the terminal receives DCI carrying a second parameter, where the second parameter is used to update the first parameter, and optionally the second parameter includes an updated reference priority candidate value set and a reference priority critical value set. The terminal repeats the foregoing steps according to the first parameter or the second parameter received recently in time.

A base station side corresponding to the terminal side,

The base station configures XR traffic for the terminal to be associated with the first logical channel group, or the base station and the terminal agree that XR traffic is associated with the first logical channel group.

The base station configures a first special PUCCH resource set for reporting the terminal scheduling reference priority information, or the base station and the terminal are defined in a PUSCH with data transmission for reporting the terminal scheduling reference priority information.

The base station determines a first parameter according to a quality of service requirement (e.g., packet delay budget, PDB) of the traffic, the first parameter comprising a reference priority candidate set and a reference priority threshold set. Optionally, the reference priority candidate set includes a low priority, a medium priority, and a high priority, and optionally, the reference priority threshold set includes a first reference priority threshold and a second reference priority threshold.

The base station configures the first parameter to the terminal through higher layer signaling.

Optionally, the base station receives PUCCHs carrying scheduling reference priority information of each terminal sent by each terminal on a first dedicated PUCCH resource set configured for all terminals, and learns the terminal scheduling reference priority information of all terminals. The base station refers to the terminal scheduling reference priority information of the terminal to determine the terminal scheduling priority, for example, when there is no service with higher priority than the XR service, the network device preferentially schedules the terminal scheduling reference priority information to be a higher (high or medium) priority terminal.

Optionally, the base station receives PUSCH in a PUSCH resource, where the PUSCH carries terminal scheduling reference priority information, a logical channel group identifier, and a data packet buffer size, and includes the step of carrying the terminal scheduling reference priority information, the logical channel group identifier, and the data packet buffer size by a MAC CE in the PUSCH. The base station obtains the logical channel group corresponding to the terminal scheduling reference priority information carried by the PUSCH MAC CE according to the logical channel group identifier, and the data of the logical channel group transmitted by the uplink transmission resource requested by the terminal, namely the terminal scheduling reference priority information which is XR service can be obtained, and the requested uplink transmission resource is used for transmitting XR service

Optionally, the base station updates the first parameter through downlink control signaling.

The base station knows the terminal scheduling reference priority information reported by all terminals, and determines the sequence of scheduling the terminals according to the terminal scheduling reference priority information reported by the base station, for example, when no service with higher priority than XR service exists, the base station preferentially schedules the terminals with higher terminal scheduling reference priority information.

According to the application condition, the base station can control the terminal scheduling reference priority information reported by the terminal through configuration, can acquire the terminal scheduling reference priority information (such as the terminal scheduling reference priority information for the data packet delay) of the terminal for a certain data packet attribute, comprehensively considers the priority of the logic channel and the reported terminal scheduling reference priority information, and can more reasonably determine the scheduling priority of the terminal. If the terminal only reports the terminal scheduling reference priority information to a certain XR service, the terminal puts the uplink data with the same XR service QoS requirement in the same logic channel group, and determines and reports the terminal scheduling reference priority information according to the attribute of the data packet in the logic channel group; after receiving the terminal scheduling reference priority information reported by different terminals and no data of a logic channel group with higher priority needs to be transmitted, the base station can schedule and order the terminals according to the terminal scheduling reference priority, wherein the scheduling reference priority is high first and then the scheduling reference priority is low (of course, the base station can also adopt other implementation methods).

The third specific application case is that the terminal reports first information, wherein the first information is of a data packet type

Terminal side:

when XR uplink data arrives, the terminal maps the XR service data to a first logical channel or a first logical channel group. The first uplink logical channel or the first logical channel group is associated with XR service, and the association of the logical channel or the logical channel group and the XR service is configured by the base station or is agreed by a protocol.

If the MAC layer of the terminal determines that there is an available PUSCH resource, where the available PUSCH resource is a PUSCH resource for carrying data, that is, the terminal has a resource that can be used for PUSCH transmission, and the terminal can carry a data packet type through the PUSCH. The PUSCH carries a packet type, a logical channel identifier or a logical channel group identifier, and a packet buffer size, including the packet type, the logical channel identifier or the logical channel group identifier, and the packet buffer size carried by the MAC CE in the PUSCH, as shown in fig. 7, where the first logical channel identifier or the first logical channel group identifier is indicated by an occupied bit field occupied by the logical channel identifier or the logical channel group identifier, the packet type is indicated by a bit field occupied by the packet type, and the packet buffer size is indicated by a bit field occupied by the data volume.

The reporting of the data packet type indicates that uplink resources are requested to the base station and used for transmitting the data packet corresponding to the data packet type.

If the MAC layer of the terminal determines that there is no available PUSCH resource at this time, the MAC layer of the terminal triggers the PHY layer to transmit a PUCCH carrying a packet type on the first dedicated PUCCH resource set, where the packet type is directly sent by the MAC layer of the terminal to the PHY layer of the terminal through internal signaling and then transmitted through the PUCCH, or the MAC layer of the terminal implicitly indicates the PHY layer, e.g. the MAC layer triggers the PHY layer to transmit the PUCCH on the first dedicated PUCCH resource set, that is, indicates that the packet information is I frame. The first special PUCCH resource set is configured by a base station and comprises a period and an offset, a terminal determines the resource of the PUCCH through the period and the offset, or the base station configures retransmission time, and the terminal does not send the PUCCH bearing the data packet type before the retransmission time is over, namely, determines the resource of the PUCCH to be sent next through the retransmission time; the first dedicated PUCCH resource set is associated with XR service, for example, the first dedicated PUCCH resource set is associated with a first logical channel or a first logical channel group (the first logical channel or the first logical channel group is associated with XR service), that is, a data packet type carried by a PUCCH transmitted on the first dedicated PUCCH resource set is a data packet type of XR service, a possible data packet type is one of an I frame and a P frame, or a data packet type is one of an I slice and a P slice. And meanwhile, the terminal sends the PUCCH to request uplink resources to the base station to transmit the data packet of the data packet type. And the PUCCH adopts a PUCCH format 0 or a PUCCH format 1.

Network side corresponding to terminal side:

the base station configures the terminal with an association of XR traffic with a first logical channel or a first logical channel group, or the base station and the terminal agree that XR traffic is associated with a first logical channel or a first logical channel group.

The base station configures a dedicated PUCCH resource set for reporting the packet type to the terminal, including a period and an offset in which the base station configures the dedicated PUCCH resource for reporting the packet type to the terminal, or a retransmission time of the packet type.

The base station receives PUCCH carrying the service data packet types of all terminals sent by all terminals on a first special PUCCH resource set configured for all terminals, and knows the data packet types of XR services of all terminals. The base station refers to the XR service data packet type of the terminal to determine the scheduling priority of the terminal, for example, when there is no service with higher priority than the XR service, the base station preferentially schedules the terminal with the XR service data packet type of I frame, or the base station performs special scheduling processing for I slice, for example, configures special transmission parameters, for example, more robust MCS level, so as to ensure successful transmission of the I slice.

The base station receives the PUSCH in the PUSCH resource, wherein the PUSCH carries the data packet type, the logic channel identification or the logic channel group identification and the data packet buffer size, and the MAC CE in the PUSCH carries the data packet type, the logic channel identification or the logic channel group identification and the data packet buffer size. As shown in fig. 7.

The base station can know which logical channel or logical channel group the data packet type carried by the PUSCH MAC CE corresponds to and which logical channel or logical channel group the uplink transmission resource requested by the terminal is used for transmitting data of which logical channel or logical channel group, i.e. can know the data packet type of which data packet type is XR service and the uplink transmission resource requested by the terminal is used for transmitting XR service.

The base station knows the XR service data packet type of all terminals. The base station refers to the data packet type of the XR service of the terminal to determine the scheduling priority of the terminal, for example, when there is no service with higher priority than the XR service, the network device preferentially schedules the terminal with the XR service data packet type of I frame, or the network device performs special scheduling processing for the I slice, for example, configures special transmission parameters, for example, a more robust MCS level, so as to ensure successful transmission of the I slice.

The application situation enables the base station to acquire the data packet type of the uplink data packet in a certain logic channel or logic channel group of the terminal (for example, the terminal can put the uplink data with the same XR service QoS requirement in the same logic channel or logic channel group and report the data packet type in the logic channel or logic channel group, so that reporting of the data packet type is only carried out on a certain XR service is realized), the priority of the logic channel and the reported data packet type are comprehensively considered, the base station can more reasonably determine the scheduling priority of the terminal, for example, after the base station receives the data packet types reported by different terminals, the base station can schedule the terminal according to the data packet type (without higher priority than the XR service), for example, the terminal with the special scheduling parameters (for example, more robust MCS (modulation scheme) are configured for I service) so as to ensure the successful transmission of I service.

The specific application case IV, the terminal reports the first information, the first information includes the data packet delay information, the terminal dispatch reference priority information and the data packet type at the same time

It should be noted that, the first information reported by the terminal may include the data packet delay information and/or the reference priority information and/or the data packet type at the same time, and the specific implementation process may refer to the specific implementation in the foregoing application case, which is not described herein again.

It should be noted that, through this application scenario, the base station may obtain the packet type, the packet delay information and the terminal scheduling reference priority information of the XR service at the same time, and the base station may optimize scheduling based on more packet information, for example, when the packet type is I frame on a plurality of terminals, the base station may determine the scheduling sequence by considering the reported packet delay information, for example, schedule the terminal reporting the I frame with the largest delay preferentially.

In summary, by applying the embodiment of the application, the network device can judge the time delay perception scheduling priority of the terminal, thereby realizing accurate scheduling, realizing reasonable resource allocation and improving the system capacity.
