Description

Information transmission method, device, equipment and storage medium

technical field

The embodiments of the present application relate to the field of communications technologies, and in particular, to an information transmission method, apparatus, device, and storage medium.

Background technique

3GPP (3rd Generation Partnership Project, 3rd Generation Partnership Project) introduced NTN (Non Terrestrial Network, non-terrestrial communication network) technology in the 5G NR (New Radio, new air interface) system.

NTN generally uses satellite communication to provide communication services to terrestrial users. Compared with the terrestrial cellular network communication system, the NTN system has many unique advantages. First of all, the NTN system is not limited by the user's area. Since a satellite can cover a large ground, and the satellite can orbit around the earth, theoretically every corner of the earth can be covered by the NTN system. Secondly, the NTN system has great social value. The NTN system can be covered at a low cost in remote mountainous areas, poor and backward countries or regions, so that people in these regions can enjoy advanced voice communication and mobile Internet technology. It is conducive to narrowing the digital divide with developed regions and promoting the development of these regions. Again, the NTN system has a long distance, and the communication cost does not increase significantly when the communication distance increases. Finally, the NTN system has high stability and is not limited by natural disasters.

However, in the NTN technology, since the information transmission delay between the UE (User Equipment, user equipment) and the satellite is relatively large, 3GPP introduced some methods to reduce the information transmission delay in the process of standardizing the NTN technology. These methods of reducing the information transmission delay may affect the UE's uplink resource scheduling. Therefore, further discussion and research are needed for uplink resource scheduling.

detailed description

In order to make the objectives, technical solutions and advantages of the present application clearer, the embodiments of the present application will be further described in detail below with reference to the accompanying drawings.

The network architecture and service scenarios described in the embodiments of the present application are for the purpose of illustrating the technical solutions of the embodiments of the present application more clearly, and do not constitute a limitation on the technical solutions provided by the embodiments of the present application. The evolution of new business scenarios and the emergence of new business scenarios, the technical solutions provided in the embodiments of the present application are also applicable to similar technical problems.

Please refer to FIG. 1 , which shows a schematic diagram of a communication system provided by an embodiment of the present application. The communication system may include: a network device 10 and a terminal device 20 .

The network device 10 is a device for providing a wireless communication service for the terminal device 20 . A connection can be established between the network device 10 and the terminal device 20 through an air interface, so as to perform communication through the connection, including the interaction of signaling and data. The number of network devices 10 may be multiple, and communication between two adjacent network devices 10 may also be performed in a wired or wireless manner. The terminal device 20 can switch between different network devices 10 , that is, establish connections with different network devices 10 .

In an example, as shown in FIG. 2 , taking an NTN network as an example, the network device 10 in the NTN network may be a satellite 11 . A satellite 11 can cover a certain range of ground areas and provide wireless communication services for terminal devices 20 on the ground areas. In addition, the satellites 11 can orbit around the earth, and by arranging a plurality of satellites 11, communication coverage of different areas on the earth's surface can be achieved.

Compared with terrestrial cellular communication networks, satellite communication has many unique advantages. First of all, satellite communication is not limited by the user's geographical area. For example, general terrestrial communication cannot cover areas such as oceans, mountains, deserts, etc. where communication equipment cannot be set up or cannot be covered due to sparse population. For satellite communication, due to a single Satellites can cover a large ground, and satellites can orbit around the earth, so theoretically every corner of the earth can be covered by satellite communications. Secondly, satellite communication has great social value. Satellite communications can be covered at low cost in remote mountainous areas and poor and backward countries or regions, so that people in these regions can enjoy advanced voice communication and mobile Internet technologies, which is conducive to narrowing the digital divide with developed regions and promoting development in these areas. Thirdly, the satellite communication distance is long, and the communication cost does not increase significantly when the communication distance increases; finally, the satellite communication has high stability and is not limited by natural disasters.

Communication satellites are classified into LEO (Low-Earth Orbit, low earth orbit) satellites, MEO (Medium-Earth Orbit, medium earth orbit) satellites, GEO (Geostationary Earth Orbit, geosynchronous orbit) satellites, HEO (High Earth orbit) satellites according to the different orbital altitudes. Elliptical Orbit, high elliptical orbit) satellites, etc. The main research at this stage is LEO and GEO.

1. LEO

The altitude range of low-orbit satellites is 500km to 1500km, and the corresponding orbital period is about 1.5 hours to 2 hours. The signal propagation delay of single-hop communication between users is generally less than 20ms. The maximum satellite viewing time is 20 minutes. The signal propagation distance is short, the link loss is small, and the transmit power requirements of the user terminal are not high.

2. GEO

A satellite in geosynchronous orbit with an orbital altitude of 35,786km and a 24-hour rotation period around the earth. The signal propagation delay of single-hop communication between users is generally 250ms.

In order to ensure the coverage of satellites and improve the system capacity of the entire satellite communication system, satellites use multiple beams to cover the ground. A satellite can form dozens or even hundreds of beams to cover the ground; a satellite beam can cover tens to hundreds of kilometers in diameter. ground area.

In another example, as shown in FIG. 3 , taking the cellular communication network as an example, the network device 10 in the cellular communication network may be the base station 12 . The base station 12 is a device deployed in an access network to provide a wireless communication function for the terminal device 20 . Base stations 12 may include various forms of macro base stations, micro base stations, relay stations, access points, and the like. In systems using different wireless access technologies, the names of devices with network device functions may be different, for example, in a 5G NR (New Radio, new air interface) system, it is called gNodeB or gNB. As communication technology evolves, the name "base station" may change. For convenience of description, in the embodiments of the present application, the above-mentioned apparatuses for providing a wireless communication function for the terminal device 20 are collectively referred to as network devices.

In addition, the terminal device 20 involved in the embodiments of the present application may include various handheld devices with wireless communication functions, vehicle-mounted devices, wearable devices, computing devices, or other processing devices connected to wireless modems, as well as various forms of user Equipment (User Equipment, UE), mobile station (Mobile Station, MS), terminal equipment (terminal device) and so on. For convenience of description, in the embodiments of the present application, the devices mentioned above are collectively referred to as terminal devices.

In addition, in the embodiments of the present application, the terms "network" and "system" are often used interchangeably, but those skilled in the art can understand their meanings.

The technical solutions provided in the embodiments of the present application may be applicable to NTN systems or cellular network systems.

In an example, NR has a two-level retransmission mechanism: the HARQ (Hybrid Automatic Repeat Request) mechanism at the MAC (Medium Access Control) layer and the RLC (Radio Link Control, Radio Link Control) mechanism ) layer ARQ (Automatic Repeat Request, automatic repeat request) mechanism. Among them, the HARQ mechanism of the MAC layer can provide fast retransmission; the ARQ mechanism of the RLC layer can provide reliable data transmission. Optionally, the retransmission of lost or erroneous data is mainly handled by the HARQ mechanism of the MAC layer, supplemented by the ARQ mechanism of the RLC layer.

The HARQ mechanism can use the Stop-and-Wait Protocol to send data. In the stop-and-wait protocol, after the sender sends a TB (Transport Block), it stops and waits for the confirmation message. It is precisely because the sender stops and waits for acknowledgment after each transmission of a TB, resulting in low user throughput. Therefore, NR uses multiple parallel HARQ processes. When one HARQ process is waiting for acknowledgment information, the sender can use another HARQ process. A HARQ process continues to send data, and these parallel HARQ processes together form a HARQ entity. The HARQ entity combines the stop-and-wait protocol to achieve the effect of continuous data transmission. Optionally, the HARQ includes uplink HARQ and downlink HARQ, wherein the uplink HARQ is for uplink data transmission; the downlink HARQ is for downlink data transmission, and the two are independent of each other.

Each serving cell corresponding to the terminal device has its own HARQ entity. Each HARQ entity maintains a set of parallel downlink HARQ processes and a set of parallel uplink HARQ processes. Optionally, the maximum number of HARQ processes supported by each uplink and downlink carrier is 16. The network device may actually determine the maximum number of HARQ processes in combination with network deployment conditions and the like. Optionally, the network device indicates the maximum number of HARQ processes to the terminal device through RRC (Radio Resource Control, radio resource control) signaling. In an example, if the network device does not provide the relevant configuration of the number of HARQ processes, the default (default) number of HARQ processes in downlink is 8, and the maximum number of HARQ processes supported by each uplink carrier is 16. Optionally, each HARQ process corresponds to a HARQ process ID. Exemplarily, for the downlink, the BCCH (Broadcast Control Channel, broadcast control channel) uses a dedicated broadcast message to broadcast the HARQ process; for the uplink, the network device uses HARQ when transmitting Msg3 (Message 3) in the random access process. ID 0, that is, the HARQ process whose process ID is 0.

Optionally, in the time domain, HARQ is divided into synchronous HARQ and asynchronous HARQ; in the frequency domain, HARQ is divided into non-adaptive HARQ and adaptive HARQ. The asynchronous HARQ refers to HARQ in which retransmission can occur at any time, that is, the time interval between the retransmission of the same TB and the previous transmission is not fixed. Adaptive HARQ refers to the ability to change the frequency domain resources and MCS (Modulation and Coding Scheme, modulation and coding strategy) used for retransmission. Optionally, in NR, the asynchronous adaptive HARQ mechanism is used for both uplink and downlink transmission.

Optionally, for a terminal device that does not support downlink space division multiplexing, each downlink HARQ process simultaneously processes one TB; for a terminal device that supports downlink space division multiplexing, each downlink HARQ process simultaneously processes one or two TBs. TB. Optionally, each uplink HARQ process of the terminal device simultaneously processes 1 TB.

In an example, the terminal device sends a BSR (Buffer Status Report, buffer status report) to the network device, so that the network device knows the amount of upstream buffered data of the terminal device, so that the network device can perform uplink according to the amount of data provided by the terminal device. schedule. Optionally, in order to save the BSR reporting overhead, the BSR adopts the way of packet reporting. In the group reporting method, each uplink logical channel corresponds to an LCG (Logical Channel Group, logical channel group), and multiple uplink logical channels can correspond to the same LCG. Optionally, the correspondence between the LC and the LCG is configured by the network device through RRC signaling. In the way of packet reporting, the terminal device reports the BSR based on the LCG. Optionally, in the NR system, each terminal device can support up to 8 LCGs.

Optionally, the triggering condition of the BSR includes at least one of the following:

(1) There is uplink data arriving in a logical channel with a higher priority in the logical channel corresponding to the terminal device, which will trigger the Regular BSR (conventional BSR);

(2) The padding (filling) part of the uplink resources allocated for the terminal equipment can carry the BSR MAC CE (Control Element, control unit) after carrying other uplink data, and in this case, the Padding BSR will be issued;

(3) The retxBSR-Timer (retransmission BSR timer) times out, and there is currently at least one uplink logical channel with uplink data to be transmitted, and the Regular BSR will be triggered at this time;

(4) The periodicBSR-Timer (periodic BSR timer) times out, and the Periodic (periodic) BSR will be triggered at this time.

Optionally, if there are multiple logical channels that trigger the Regular BSR at the same time, each of these logical channels triggers a separate Regular BSR. Optionally, the BSR is carried through the BSR MAC CE.

In an example, the terminal device applies to the network device for uplink resources through an SR (Scheduling Request, scheduling request). Optionally, when the terminal device triggers Regular BSR, and the terminal device does not have uplink resources for transmitting new data (initial transmission), or, when the terminal device triggers Regular BSR, and the terminal device allocates If the uplink resource used to transmit new data (initial transmission) cannot carry the data to be transmitted on the uplink logical channel that triggers the Regular BSR, the terminal triggers the SR. Since the network device does not know when the terminal device needs to send uplink data, for example, it is not clear when the terminal device will send the SR, based on this, the network device can allocate periodic PUCCH (Physical Uplink Control Channel) for transmitting the SR to the terminal device. , physical uplink control channel) resources, and then the terminal device transmits SR on the allocated PUCCH resources, and the network device detects whether there is SR transmission on the allocated PUCCH resources.

It can be seen from the above trigger conditions of SR that SR is based on logical channels. For each uplink logical channel, the network device may choose whether to configure the PUCCH resource for transmitting the SR for the uplink logical channel. In the case that an uplink logical channel triggers an SR, if the network device configures a PUCCH resource for transmitting an SR for the uplink logical channel, the terminal device sends an SR on the PUCCH resource corresponding to the logical channel for transmitting an SR; Otherwise, the terminal device will initiate random access.

Optionally, the network device may configure multiple PUCCH resources for transmitting the SR for the terminal device. For an uplink logical channel, if the network device configures the PUCCH resource for SR transmission for the uplink logical channel, on each uplink BWP (Bandwidth Part, working bandwidth), the network device configures at most one for the logical channel for PUCCH resource for transmitting SR. Optionally, each PUCCH resource used for transmitting SR corresponds to the following configuration parameters:

(1) PUCCH resource cycle and slot/time symbol offset;

(2) PUCCH resource index.

In an example, the following relationship exists between LogicalChannelIdentity (logical channel identifier), SchedulingRequestId (scheduling request identifier), SchedulingRequestResourceId (scheduling request resource identifier) and PUCCH-ResourceId (uplink control channel resource identifier):

(1) Each LogicalChannelIdentity can indicate one or more SchedulingRequestId;

(2) Each SchedulingRequestResourceId can indicate one or more SchedulingRequestId;

(3) Each SchedulingRequestResourceId may indicate one or more PUCCH-ResourceIds.

In view of the large delay of wireless signal transmission between terminal equipment and network equipment (such as satellites) in the NTN system, 3GPP is discussing introducing the HARQ function to be disabled in the NTN standardization process to reduce the data transmission delay. For the configuration of enabling/disabling the HARQ function, 3GPP has agreed:

For downlink, the configuration of enabling/disabling the HARQ function can be performed based on the terminal equipment and based on the HARQ process;

For the uplink, the configuration of enabling/disabling the HARQ function can be performed based on the terminal device, based on the HARQ process, and based on the logical channel.

Because different services have different QoS (Quality of Service, quality of service) requirements, for example, some services are sensitive to delay, and some services have strict requirements on packet loss rate. For delay-sensitive services, the HARQ process with the HARQ function disabled can be used for transmission, thereby reducing the transmission delay; for services with strict requirements on the packet loss rate, the HARQ process with the HARQ function enabled can be used for transmission, thereby improving transmission reliability. sex.

For downlink data transmission, the network can accurately know the buffer (buffer) information of each logical channel, so it can perform downlink scheduling according to the data transmission requirements of each service combined with the QoS requirements. For uplink data transmission, the terminal equipment needs to let the network equipment know the buffer status of the terminal equipment side through the BSR. When a certain uplink logical channel of the terminal equipment triggers the regular BSR and there is no UL grant (uplink grant) available for initial transmission, the terminal equipment This upstream logical channel of the device will trigger SR. Optionally, each logical channel of the terminal device can trigger its own SR. When the terminal device receives a UL grant that is sufficient to accommodate all the data to be transmitted, it cancels all pending SRs (resolved SRs).

In addition, since the BSR is reported in LCG units, multiple uplink logical channels may be mapped to the same LCG, so the network cannot accurately know the respective buffer status of the uplink logical channels with HARQ enabled or disabled. In NTN, if an LCG contains both a logical channel with HARQ enabled and a logical channel with HARQ disabled, the network device cannot determine whether to assign a UL grant with HARQ enabled or to disable HARQ through the existing SR/BSR mechanism. Functional UL grant.

Based on this, the embodiments of the present application provide an information transmission method, which can be used to enhance the SR mechanism and the BSR mechanism for the configuration method of enabling/disabling the HARQ function introduced in NTN, so as to assist the network device in enabling and disabling the HARQ function. Differentiate uplink scheduling.

The technical solutions of the present application will be described below with reference to several embodiments.

Please refer to FIG. 4 , which shows a flowchart of an information transmission method provided by an embodiment of the present application. The method can be applied to the communication systems shown in FIGS. 1 to 3 , and the method may include the following steps:

Step 410: In the case that at least one uplink logical channel corresponding to the terminal device triggers a scheduling request, the terminal device sends a scheduling request to the network device, and the scheduling request is used to request scheduling of uplink resources.

The network device is configured with at least one uplink logical channel for the terminal device. The embodiment of this application does not limit the specific type of the uplink logical channel. Optionally, the uplink logical channel includes a CCCH (Common Control Channel, common control channel); The channel includes DCCH (Dedicated Control Channel, dedicated control channel); or, the uplink logical channel includes DTCH (Dedicated Traffic Channel, dedicated traffic channel).

The scheduling request is used to request scheduling of uplink resources to transmit data to be transmitted on the uplink logical channel. It can be known from the above description that the scheduling request is based on the uplink logical channel, that is, the scheduling request is triggered by the uplink logical channel. This embodiment of the present application does not limit the specific triggering conditions of the scheduling request. Optionally, a regular buffer status report (regular BSR) is triggered on an uplink logical channel, and there is no uplink configured for the uplink logical channel for initial transmission. In the case of resources, the uplink logical channel triggers a scheduling request; or, when an uplink logical channel triggers a buffer status report, and the uplink resource configured for the uplink logical channel for initial transmission cannot carry the buffer status report, The uplink logical channel triggers a scheduling request.

In the embodiment of the present application, in the case that at least one uplink logical channel (or at least one uplink logical channel corresponding to the terminal device) configured by the network device for the terminal device triggers a scheduling request, the terminal device may send the scheduling request to the network device . Optionally, for an uplink logical channel that triggers a scheduling request, the terminal device can send the scheduling request triggered by the uplink logical channel to the network device only when the uplink logical channel is configured with uplink resources for transmitting the scheduling request. request, that is, the above step 410 includes: for the first uplink logical channel in the at least one uplink logical channel, when the first uplink logical channel is configured with uplink resources for transmitting the scheduling request, the terminal device sends the first uplink logical channel to the network device. A scheduling request triggered by an uplink logical channel. This embodiment of the present application does not limit the uplink resource used for transmitting the scheduling request. Optionally, the uplink resource used for transmitting the scheduling request is a PUCCH resource.

Step 420, the network device sends an uplink grant to the terminal device, where the uplink grant is used to carry the data to be transmitted on the uplink logical channel whose HARQ attribute is the first attribute, and the HARQ attribute includes enabling the HARQ function and disabling the HARQ function.

After receiving the scheduling request from the terminal device, the network device may send an uplink (UL, Uplink) grant to the terminal device to allocate uplink resources for transmitting data to be transmitted on the uplink logical channel for the terminal device. Optionally, the uplink resource includes an uplink RB (Resource Block, resource block).

In the embodiment of the present application, the uplink grant sent by the network device to the terminal device is used to carry the data to be transmitted on the uplink logical channel whose HARQ attribute is the first attribute. It can be known from the above description that the HARQ attribute includes enabling the HARQ function and disabling the HARQ function. In this embodiment of the present application, the first attribute includes enabling the HARQ function or disabling the HARQ function. When the first attribute is to enable the HARQ function, the uplink grant is used to carry the data to be transmitted on the uplink logical channel with the HARQ function turned on; when the first attribute is to turn off the HARQ function, the uplink grant is used to carry the HARQ function turned off. Data to be transmitted on the uplink logical channel.

Step 430, the terminal device cancels the first scheduling request, where the first scheduling request refers to a scheduling request triggered by an uplink logical channel whose HARQ attribute is the first attribute.

After receiving the uplink grant, the terminal device can cancel the corresponding HARQ attribute uplink logical channel scheduling request according to the uplink grant, so as to prevent the terminal device from continuously sending scheduling requests triggered by the HARQ attribute uplink logical channel to the network device. In the embodiment of the present application, the uplink grant is used to carry the data to be transmitted on the uplink logical channel whose HARQ attribute is the first attribute. After receiving the uplink grant, the terminal device cancels the triggering of the uplink logical channel whose HARQ attribute is the first attribute. scheduling request.

In an example, the uplink grant indicates the HARQID of the uplink process used for PUSCH (Physical Uplink Share Channel) transmission. Since uplink processes with different HARQ IDs correspond to different HARQ attributes, the terminal device can Specify the HARQ attribute of the uplink logical channel corresponding to the data to be transmitted carried by the uplink grant. For example, if the uplink grant indicates that the HARQ attribute of the uplink process used for PUSCH transmission is the HARQ attribute enabled, the terminal device clarifies that the HARQ attribute of the uplink logical channel corresponding to the data to be transmitted carried by the uplink grant is the HARQ attribute enabled, and then the terminal device cancels the HARQ attribute. The HARQ attribute is a scheduling request triggered by an uplink logical channel with the HARQ attribute enabled.

Compared with the related art in which the terminal equipment receives the uplink grant to cancel the scheduling request triggered by all the uplink logical channels, the embodiment of the present application distinguishes and cancels the scheduling request triggered by the uplink logical channel with different HARQ attributes according to the difference of the HARQ attributes corresponding to the uplink grant. Since different HARQ attributes correspond to different QoS requirements, the embodiment of the present application ensures the QoS of the HARQ attribute corresponding to the uplink grant by canceling the scheduling request triggered by the uplink logical channel of the HARQ attribute corresponding to the uplink grant, while avoiding affecting the QoS of the HARQ attribute corresponding to the uplink grant. The QoS of uplink logical channels with different HARQ attributes is beneficial for all uplink logical channels with different HARQ attributes to meet the QoS requirements.

In order to further ensure that the QoS requirements are met, optionally, the above step 430 includes: canceling the first scheduling request in the case that the uplink authorization can carry the data to be transmitted on all uplink logical channels whose HARQ attribute is the first attribute. That is, when the terminal device receives an uplink grant, but the uplink grant cannot carry data to be transmitted on all uplink logical channels whose HARQ attribute is the first attribute, the terminal device does not cancel the first scheduling request.

After the terminal device sends a scheduling request to the network device, it will start the timer corresponding to the scheduling request, and the transmission of the scheduling request is prohibited in the time period when the timer is activated, thereby preventing the terminal device from sending scheduling requests to the network device too frequently. ask. Therefore, when the terminal device cancels a scheduling request or after canceling the scheduling request, in order to avoid wasting the processing overhead of the terminal device, the terminal device may stop the timer corresponding to the scheduling request. Therefore, in an example, after the above step 420, the method further includes: stopping the first timer corresponding to the first scheduling request, where the first timer is used to indicate a time period during which transmission of the first scheduling request is prohibited. Optionally, the first timer is sr-ProhibitTimer (Scheduling Request Prohibit Timer).

In order to ensure that the QoS requirements are met, optionally, the above-mentioned stopping the first timer corresponding to the first scheduling request includes: in the case that the uplink grant can carry data to be transmitted on all uplink logical channels whose HARQ attribute is the first attribute, stopping The first timer corresponding to the first scheduling request. That is, when the terminal device receives the uplink grant, but the uplink grant cannot carry the data to be transmitted on all uplink logical channels whose HARQ attribute is the first attribute, the terminal device does not stop the first timer corresponding to the first scheduling request. , so as to continue to send the first scheduling request to the network device.

For example, as shown in FIG. 5 , it is assumed that two uplink logical channels corresponding to the terminal device trigger scheduling requests respectively, and the two uplink logical channels are LC 1 and LC 2 respectively. Among them, the HARQ attribute of LC 1 is "enable HARQ function", the HAR attribute of LC 2 is "disable HARQ function", the scheduling request triggered by LC 1 is SR1, and the scheduling request triggered by LC 2 is SR2. Assuming that the network device is configured with uplink resources for transmitting scheduling requests for both LC 1 and LC 2, the terminal device can send SR1 and SR2 to the network device. At a certain moment after the terminal device sends the SR, the terminal device can start the prohibition timer sr-ProhibitTimer, and then after the sr-ProhibitTimer times out, the terminal device can send the SR to the network device again. As shown in Figure 5, the terminal device receives the uplink authorization sent by the network device, the uplink authorization is used to carry the data to be transmitted of the uplink logical channel of "HARQ function is turned off", and the uplink authorization can carry the data to be transmitted of the LC 2, Therefore, the terminal device cancels SR2 and stops the sr-ProhibitTimer corresponding to SR2.

It should be noted that, in this embodiment of the present application, when the terminal device receives an uplink grant, and the uplink grant can carry the data to be transmitted on all uplink logical channels whose HARQ attribute is the first attribute, the terminal device can cancel the HARQ attribute. The scheduling request is triggered for the uplink logical channel of the first attribute, and the first timer corresponding to the scheduling request triggered by the uplink logical channel whose HARQ attribute is the first attribute is stopped.

To sum up, the technical solutions provided by the embodiments of the present application, after receiving the uplink grant sent by the network device through the terminal device, cancel the scheduling request triggered by the uplink logical channel of the HARQ attribute corresponding to the uplink grant, compared with the related art. When the terminal device receives the uplink grant to cancel the scheduling request triggered by all uplink logical channels, the embodiment of the present application distinguishes and cancels the scheduling request triggered by the uplink logical channel with different HARQ attributes according to different HARQ attributes corresponding to the uplink grant. Since different HARQ attributes correspond to different QoS requirements, the embodiment of the present application ensures the QoS of the HARQ attribute corresponding to the uplink grant by canceling the scheduling request triggered by the uplink logical channel of the HARQ attribute corresponding to the uplink grant, while avoiding affecting the QoS of the HARQ attribute corresponding to the uplink grant. The QoS of uplink logical channels with different HARQ attributes is beneficial for all uplink logical channels with different HARQ attributes to meet the QoS requirements.

In addition, in the embodiment of the present application, after receiving the uplink grant sent by the network device, the terminal device stops the timer corresponding to the scheduling request triggered by the uplink logical channel of the HARQ attribute corresponding to the uplink grant. Since the terminal device starts a timer corresponding to the scheduling request after sending a scheduling request to the network device, the transmission of the scheduling request is prohibited in the time period when the timer is activated, thereby preventing the terminal device from sending scheduling requests to the network device too frequently. . Therefore, when the terminal device cancels the scheduling request or after canceling the scheduling request, the terminal device can stop the timer corresponding to the scheduling request to avoid wasting the processing overhead of the terminal device.

As can be seen from the above description, in order to ensure that the terminal device can send the scheduling request to the network device, the network device can configure the terminal device with uplink resources for transmitting the scheduling request, and configure the related configuration of the scheduling request.

Grant, in this embodiment of the present application, the network device configures different scheduling request configurations and/or different uplink resource configurations for uplink logical channels with different HARQ attributes. That is, uplink logical channels with different HARQ attributes correspond to different scheduling request configurations, and/or uplink logical channels with different HARQ attributes correspond to different uplink resource configurations.

This embodiment of the present application does not limit the representation of different scheduling request configurations. Optionally, different scheduling request configurations represent that the working duration of the first timer is different; or, different scheduling request configurations represent that the maximum number of transmissions is different. The same; or, different scheduling request configurations show that the working duration and the maximum number of transmissions of the first timer are different. For example, for an uplink logical channel with "HARQ function enabled", configure a scheduling request with a maximum number of transmissions of 5 times; for an uplink logical channel with "HARQ function disabled", configure a scheduling request with a maximum number of transmission times of 10 times.

Optionally, the above configuration information further includes at least one of the following: process number configuration, used to configure the number of uplink HARQ processes supported by the terminal device; process attribute configuration, used to configure the attributes of the uplink HARQ process supported by the terminal device; channel attribute configuration , used to configure the HARQ attribute of each uplink logical channel; association configuration, used to configure the association between the scheduling request and the uplink resources, optionally, each scheduling request corresponds to at least one uplink resource used for transmitting the scheduling request . Optionally, for each uplink logical channel, the network device may select whether to configure an uplink resource for transmitting a scheduling request for the uplink logical channel. In the case where the network device chooses to configure the uplink resource for the uplink logical channel for transmitting the scheduling request, the network device may configure a corresponding scheduling request configuration for the uplink logical channel, and the scheduling request is configured in each service of the terminal device. Each uplink working bandwidth of the cell corresponds to one or more uplink resources for transmitting scheduling requests.

To sum up, in the technical solutions provided by the embodiments of the present application, the network device configures the scheduling request and uplink resources for the terminal device, so as to ensure that when the uplink logical channel corresponding to the terminal device triggers the scheduling request, the network device can send the scheduling request to the network device.

Step 610: The network device sends configuration information to the terminal device, where the configuration information includes at least one of the following: scheduling request configuration and uplink resource configuration. The scheduling request configuration is used to configure the first timer corresponding to the scheduling request and/or the maximum number of times of transmission of the scheduling request; the uplink resource configuration is used to configure uplink resources for transmitting the scheduling request. Optionally, the configuration information sent by the network device to the terminal device is carried in RRC signaling.

Step 620: In the case that at least one uplink logical channel corresponding to the terminal device triggers a scheduling request, the terminal device sends a scheduling request to the network device. The scheduling request is used to request scheduling of uplink resources to transmit data to be transmitted on the uplink logical channel. Optionally, for the first uplink logical channel in the at least one uplink logical channel, in the case that the first uplink logical channel is configured with uplink resources for transmitting scheduling requests, the terminal device sends the first uplink logical channel trigger to the network device. Schedule request.

Step 630: The network device sends an uplink grant to the terminal device, where the uplink grant is used to carry the data to be transmitted on the uplink logical channel whose HARQ attribute is the first attribute. The HARQ attribute includes enabling the HARQ function and disabling the HARQ function. In this embodiment of the present application, the first attribute includes enabling the HARQ function or disabling the HARQ function. When the first attribute is to enable the HARQ function, the uplink grant is used to carry the data to be transmitted on the uplink logical channel with the HARQ function turned on; when the first attribute is to turn off the HARQ function, the uplink grant is used to carry the HARQ function turned off.

Optionally, in the case that the uplink grant can carry the to-be-transmitted data of all uplink logical channels whose HARQ attribute is the first attribute, the first timer corresponding to the first scheduling request is stopped.

It should be noted that this embodiment of the present application does not limit the execution sequence of step 640 and step 650. Optionally, step 640 is executed before step 650; or, step 640 and step 650 are executed simultaneously.

Please refer to FIG. 7, which shows a flowchart of an information transmission method provided by an embodiment of the present application. The method can be applied to the communication systems shown in FIG. 1 to FIG. 3. The method may include the following steps:

Step 710: In the case where at least one uplink logical channel in the first uplink logical channel group corresponding to the terminal device triggers a buffer status report, the terminal device sends a buffer status report to the network device; wherein the buffer status report is used to indicate the first uplink logical channel. The HARQ attribute in the channel group is the sum of the amount of data to be transmitted on the uplink logical channels with the HARQ function enabled, and the HARQ attribute is the sum of the amount of data to be transmitted on the uplink logical channels with the HARQ function disabled.

As can be seen from the description of the above embodiments, the terminal device sends a buffer status report to the network device, so that the network device knows the uplink buffer data volume of the terminal device, so that the network device can perform uplink scheduling according to the data volume provided by the terminal device. In addition, in order to save the BSR reporting overhead, the BSR adopts a packet reporting method. In the group reporting mode, each uplink logical channel corresponds to an uplink logical channel group, and multiple uplink logical channels may correspond to the same uplink logical channel group. That is, when a buffer status report is triggered for a certain uplink logical channel corresponding to the terminal device, the amount of data to be transmitted that is mapped to the uplink logical channel group corresponding to the uplink logical channel is sent to the network device.

Based on this, in order to enable the network device to specify the amount of data to be transmitted on uplink logical channels with different HARQ attributes in a certain uplink logical channel group, it is convenient for the network device to determine how to perform uplink scheduling according to the amount of data to be transmitted on uplink logical channels with different HARQ attributes. . Therefore, in this embodiment of the present application, the buffer status report sent by the terminal device to the network device is used to indicate the respective amounts of data to be transmitted on the uplink logical channels with different HARQ attributes in the uplink logical channel group. When at least one uplink logical channel in an uplink logical channel group triggers a buffer status report, the buffer status report is sent to the network device, and the buffer status report is used to indicate that the HARQ attribute in the first uplink logical channel group is the uplink with the HARQ function enabled The sum of the amount of data to be transmitted on the logical channel, and the sum of the amount of data to be transmitted on the uplink logical channel whose HARQ attribute is the HARQ function disabled.

The embodiment of the present application does not limit the specific content of the cache status report. The following exemplarily shows several representations of the contents of the cache status report provided by the embodiment of the present application.

In an example, the buffer status report includes at least one of the following items: the sum of the amount of data to be transmitted on the uplink logical channels included in the first uplink logical channel group, and the uplink logical channel whose HARQ attribute in the first uplink logical channel group is to enable the HARQ function The sum of the amount of data to be transmitted by the channel.

Since the first uplink logical channel group includes two possible uplink logical channels with HARQ attributes, they are an uplink logical channel with the HARQ function enabled and an uplink logical channel with the HARQ function disabled. Therefore, as long as it is clear that the sum of the amount of data to be transmitted on the uplink logical channels included in the first uplink logical channel group, and the sum of the amount of data to be transmitted on the uplink logical channels whose HARQ attribute is enabled with the HARQ function in the first uplink logical channel group, that is, It can be clarified that the HARQ attribute in the first uplink logical channel group is the sum of the to-be-transmitted data volumes of the uplink logical channels with the HARQ function disabled. Optionally, the sum of the amount of data to be transmitted in the uplink logical channel group with the HARQ function disabled is equal to the sum of the amount of data to be transmitted in the uplink logical channel included in the first uplink logical channel group minus the amount of data to be transmitted in the uplink logical channel with the HARQ function enabled. The sum of the amount of data transferred.

In order to reduce the size of the buffer status report, avoid adding invalid information to the buffer status report, reduce the resource overhead of the BSR of the terminal device, and improve the transmission and parsing efficiency of the buffer status report, optionally, in the first uplink logical channel group When the HARQ attribute is that the uplink logical channel with the HARQ function enabled has no data to be transmitted, the buffer status report includes the sum of the to-be-transmitted data volume of the uplink logical channel included in the first uplink logical channel group. That is, in this case, the sum of the amount of data to be transmitted on the uplink logical channels included in the first uplink logical channel group in the buffer status report is the amount of data to be transmitted on the uplink logical channel whose HARQ attribute is to disable the HARQ function.

In another example, the buffer status report includes at least one of the following items: the sum of the to-be-transmitted data volumes of the uplink logical channels included in the first uplink logical channel group, and the uplink whose HARQ attribute in the first uplink logical channel group is to disable the HARQ function. The sum of the amount of data to be transmitted for the logical channel.

Since the first uplink logical channel group includes two possible uplink logical channels with HARQ attributes, they are an uplink logical channel with the HARQ function enabled and an uplink logical channel with the HARQ function disabled. Therefore, as long as it is clear that the sum of the amount of data to be transmitted on the uplink logical channels included in the first uplink logical channel group, and the sum of the amount of data to be transmitted on the uplink logical channels whose HARQ attribute is the HARQ function disabled in the first uplink logical channel group, that is, It can be clarified that the HARQ attribute in the first uplink logical channel group is the sum of to-be-transmitted data volumes of uplink logical channels with the HARQ function enabled. Optionally, the sum of the amount of data to be transmitted in the uplink logical channel group with the HARQ function enabled is equal to the sum of the amount of data to be transmitted in the uplink logical channel included in the first uplink logical channel group minus the amount of data to be transmitted in the uplink logical channel with the HARQ function disabled. The sum of the amount of data transferred.

In order to reduce the size of the buffer status report, avoid adding invalid information to the buffer status report, reduce the resource overhead of the terminal device BSR, and improve the transmission and parsing efficiency of the buffer status report, optionally, in the first uplink logical channel group HARQ In the case that the uplink logical channel whose attribute is the HARQ function is enabled has no data to be transmitted, the buffer status report includes the sum of the to-be-transmitted data amount of the uplink logical channel included in the first uplink logical channel group. That is, in this case, the sum of the amount of data to be transmitted on the uplink logical channels included in the first uplink logical channel group in the buffer status report is the amount of data to be transmitted on the uplink logical channel whose HARQ attribute is HARQ enabled.

In yet another example, the buffer status report includes: the sum of the amount of data to be transmitted on the uplink logical channels whose HARQ attribute is to enable the HARQ function in the first uplink logical channel group, and the pending transmission of the uplink logical channels whose HARQ attribute is to disable the HARQ function The sum of the amount of data.

The first uplink logical channel group includes two possible uplink logical channels with HARQ attributes, which are an uplink logical channel with HARQ function enabled and an uplink logical channel with HARQ function disabled. Therefore, it is possible to directly indicate in the buffer status report the sum of the quantities to be transmitted corresponding to the uplink logical channels of the two HARQ attributes, which is more beneficial for the network device to quickly grasp the uplink logical channels of different HARQ attributes in the first logical channel group. The sum of the number of pending transfers.

For example, as shown in FIG. 8 , it is assumed that the first uplink logical channel group is LCG 0, and the first uplink logical channel group includes four uplink logical channels, namely LC 1, LC 2, LC 3 and LC 4. Among them, the HARQ attribute of LC 1 and LC 2 is to enable the HARQ function, and the HARQ attribute of LC 3 and LC 4 is to disable the HARQ function. Then for LCG 0, when at least one uplink logical channel in LCG 0 triggers the BSR, the BSR sent by the terminal device to the network device may include: the sum of the amount of data to be transmitted of LC 1 and LC 2, and the sum of LC 3 and LC The sum of the amount of data to be transmitted of 4, that is, the terminal device reports a BO (Buffer Occupy, buffer occupation) to the network device for uplink logical channels with different HARQ attributes.

To sum up, in the technical solutions provided by the embodiments of the present application, the buffer status report is uploaded to the network device through the terminal device, and the buffer status report indicates the sum of the number of uplink logical channels with different HARQ attributes in the uplink logical channel group to be transmitted. , so that the network device can specify the amount of data to be transmitted on the uplink logical channels with different HARQ attributes in the uplink logical channel group, so that the subsequent network device can determine how to perform uplink scheduling according to the amount of data to be transmitted on the uplink logical channels with different HARQ attributes. The uplink scheduling is performed on the auxiliary network equipment to ensure that the uplink scheduling of the network equipment matches the service transmission requirements of the terminal equipment, and the QoS requirements corresponding to different HARQ attributes are guaranteed.
