Description

Data transmission method, device and system

technical field

The present application relates to the field of wireless communication, in particular to a data transmission method, device and system.

Background technique

Non-terrestrial network (Non Terrestrial Network, NTN) technology is a technology that uses satellite communication to provide communication services to ground users. Compared with ground communication, it has many advantages. For example, NTN technology can provide services for areas where ground communication is difficult to cover without being restricted by user regions. For example, for mountainous, desert, and sea areas, NTN technology has lower communication costs than ground communication.

It is precisely because the NTN technology has many unique advantages that the Third Generation Partnership Project (Third Generation Partnership Project, 3GPP) has started research work on the integration of satellite communications and ground communications. In the process of integrating satellite communication with terrestrial communication, the functions or protocols of the fifth-generation mobile communication technology (5th-Generation, 5G) New Radio (NR) suitable for terrestrial communication need to be properly adjusted to adapt to NTN technology. For example, for the NTN technology will cause a large propagation delay, the attribute of the HARQ process is not only enabled, but the HARQ process whose attribute is disabled is introduced in 3GPP to reduce the data transmission delay.

However, in the uplink transmission process, since different service data have different Quality of Service (QoS), different QoS can use HARQ processes with different attributes, and different logical channels can have different QoS requirements, which will make it difficult to guarantee the QoS requirements of different services during the transmission process.

Detailed ways

In order to make the purpose, technical solution and advantages of the present application clearer, the implementation manners of the present application will be further described in detail below in conjunction with the accompanying drawings.

Currently 3GPP is studying NTN technology, which generally uses satellite communication to provide communication services to ground users. Compared with terrestrial communication (such as terrestrial cellular network), satellite communication has many unique advantages. First of all, satellite communication is not restricted by the user's region. For example, general land communication cannot cover areas where communication equipment cannot be set up, such as oceans, mountains, and deserts, or areas where communication coverage is not possible due to sparse population. For satellite communication, since a satellite can cover a large ground area, and satellites can orbit the earth, theoretically every corner of the earth can be covered by satellite communication. Secondly, satellite communication has great social value. Satellite communication can cover remote mountainous areas, poor and backward countries or regions at a lower cost, so that people in these regions can enjoy advanced voice communication and mobile Internet technology, which is conducive to narrowing the digital gap between these regions and developed regions, so as to promote the development of these regions. Thirdly, the satellite communication distance is long, and with the increase of the communication distance, the communication cost does not increase significantly; finally, the satellite communication has high stability and is not limited by natural disasters.

According to the orbit height of communication satellites, communication satellites can be divided into: Low-Earth Orbit (LEO) satellites, Medium-Earth Orbit (MEO) satellites, Geostationary Earth Orbit (GEO) satellites, High Elliptical Orbit (HEO) satellites, etc. At present, 3GPP mainly studies LEO satellites and GEO satellites. Among them, the orbital altitude of the LEO satellite ranges from 500 kilometers (km) 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 20 milliseconds (ms), and the maximum satellite visible time is 20 minutes. The NTN technology based on LEO satellites has the characteristics of short signal propagation distance, less link loss and low requirements on the transmission power of user terminals. The orbital height of the GEO satellite is 35786km, and the rotation period around the earth is 24 hours. The signal propagation delay of single-hop communication between users is generally 250ms. In order to ensure the coverage area of satellites on the earth and improve the system capacity of the entire satellite communication system, satellites use multi-beams to cover the ground, that is, a satellite can form dozens or even hundreds of satellite beams to cover the ground, and each satellite beam can cover a ground area with a diameter of tens to hundreds of kilometers.

In the process of integrating satellite communication with ground communication, the functions or protocols of NR applicable to ground communication need to be properly adjusted to adapt to NTN technology. For example, the HARQ mechanism in the NR protocol suitable for terrestrial communication needs to be adjusted to adapt to the integration of satellite communication and terrestrial communication.

In order to help understand the relevant description of the embodiment of the present application, here is a brief introduction to the HARQ mechanism in the NR protocol:

The NR protocol defines a two-level retransmission mechanism, which are the HARQ mechanism of the Medium Access Control (MAC) layer and the Automatic Repeat Request (ARQ) mechanism of the Radio Link Control (RLC) layer. Among them, the retransmission of lost or erroneous data is mainly processed by the HARQ mechanism of the MAC layer, and then supplemented by the retransmission function of the RLC layer. The HARQ mechanism of the MAC layer can provide fast data retransmission, and the ARQ mechanism of the RLC layer can provide reliable data transmission.

A Hybrid Automatic Repeat reQuest (HARQ) mechanism uses a Stop-and-Wait Protocol (Stop-and-Wait Protocol, also called an SQW protocol) to send data. In the stop-and-wait protocol, after sending a transmission block (Transmission Block, TB), the sender stops and waits for confirmation information. This process can also be called HARQ feedback. In this way, the sending end will stop and wait for confirmation after sending a TB, resulting in very low user throughput. Therefore, in order to improve user throughput, NR uses multiple parallel HARQ processes to send data blocks. When one HARQ process is waiting for confirmation information, the sender can use another HARQ process to continue sending data blocks. These HARQ processes collectively form a HARQ entity that incorporates a stop-and-wait protocol to allow data blocks to be sent continuously. The multiple HARQ processes include an uplink HARQ process and a downlink HARQ process. The uplink HARQ process and the downlink HARQ process are independent of each other and do not affect each other. The number of the uplink HARQ process and the downlink HARQ process may be the same. The uplink HARQ process is for the transmission of uplink data, and the downlink HARQ process is for downlink data transmission. Acknowledgment messages include ACK and NACK. If the confirmation is successfully received, the confirmation message is ACK, and if the confirmation fails, the confirmation message is NACK.

The NR protocol applicable to terrestrial communication stipulates that each serving cell corresponding to the terminal has its own HARQ entity. Each HARQ entity is responsible for maintaining a set of parallel downlink HARQ processes and a set of parallel uplink HARQ processes. Currently, each uplink carrier and downlink carrier supports up to 16 HARQ processes. The base station can indicate the maximum number of HARQ processes to the terminal through semi-static configuration of radio resource control (Radio Resource Control, RRC) signaling according to network deployment conditions. If the network does not provide corresponding configuration parameters, the default maximum number of HARQ processes supported by each downlink carrier is 8, and the maximum number of HARQ processes supported by each uplink carrier is always 16. Each HARQ process corresponds to a HARQ process number (Identity or Identification, ID). For downlink transmission, a broadcast control channel (Broadcast Control Channel, BCCH) uses a dedicated broadcast HARQ process. For uplink transmission, the third message Msg3 in the random process uses HARQ ID 0.

For terminals that do not support downlink space division multiplexing, each downlink HARQ process can only process 1 TB at a time; for terminals that support downlink space division multiplexing, each downlink HARQ process can process 1 or 2 TB at a time. Each uplink HARQ process of the terminal processes 1 TB at a time. The HARQ mechanism can be divided into a synchronous HARQ mechanism and an asynchronous HARQ mechanism in the time domain, and can be divided into a non-adaptive HARQ mechanism and an adaptive HARQ mechanism in the frequency domain. Both uplink and downlink transmissions in the NR protocol use an asynchronous adaptive HARQ mechanism. The asynchronous HARQ mechanism means that the retransmission of a TB can occur at any time. For the same TB, the time interval between its retransmission and the previous transmission is not fixed. The adaptive HARQ mechanism means that the frequency domain resources and Modulation and Coding Scheme (MCS) used by the retransmitted TB can be changed.

Secondly, a brief introduction to the semi-static resource configuration in the NR protocol:

In order to support periodic services with basically fixed traffic volume and reduce frequent Physical Downlink Control Channel (PDCCH) scheduling overhead, NR can support semi-static resource configuration. Wherein, the semi-static resource configuration refers to that the network side equipment allocates scheduling resources for the terminal through the DCI carried by the PDCCH, and the terminal sends or receives service data according to the scheduling resources every fixed period. The semi-static resource configuration may include a configuration grant (Configured Grant, CG) for an uplink transmission link (Upper Link, UL) and a semi-persistent scheduling (Semi-Persistent Scheduling, SPS) for a downlink transmission link (Down Link, DL). For CG, it can include two types, namely type 1 (type1) and type 2 (type2). Among them, type1 CG means that after the UE receives the RRC configuration, the user equipment (User Equipment, UE) can use or configure it, that is, activate it. Type2 CG means that the UE saves the RRC configuration after receiving the RRC configuration. When the DCI is subsequently received indicating that the CG is activated or deactivated, the CG resource can be activated (used) or deactivated (not used).

When configuring CG or SPS, the network side device simultaneously indicates the number of HARQ processes that can be used by the corresponding CG resource or SPS resource. The UE can calculate the HARQ process ID corresponding to the CG resource according to the HARQ process data. For example, to define variables for a maximum number of HARQ processes of 16:

nrofHARQ-Processes INTEGER(1..16),

Since the composite SPS or composite CG is supported in R16, it can be configured in the RRC accordingly, and can also indicate the HARQ process offset value (offset) at the same time. The UE can calculate the HARQ process ID corresponding to the CG resource according to the HARQ process data and the HARQ process offset.

Finally, a brief introduction to the Logic Channel (LCH) priority in the NR protocol:

In NR, the network side equipment allocates uplink transmission resources based on UE (that is, per-UE) instead of bearer (that is, per-bearer). It is up to UE to decide which radio bearer data can be put into the allocated uplink transmission resources based on UE.

Based on the uplink transmission resources configured by the network side equipment, the UE needs to determine the transmission data volume of each logical channel in the initial MAC protocol data unit (Protocol Data Unit, PDU), and in some cases, the UE also needs to allocate resources for the MAC control element (Control Element, CE). In order to realize multiplexing of uplink logical channels, it is necessary to assign a priority to each uplink logical channel. For a MAC PDU of a given size, when multiple uplink logical channels have data transmission requirements at the same time, the resources of the MAC PDU are allocated in descending order of the logical channel priorities corresponding to each uplink logical channel. That is to say, in the existing logical channel prioritization (Logical Channel prioritization, LCP) rule, only the priority of the LCH is considered, and logical channel mapping is performed, so as to perform data transmission.

Specifically, for different signals and/or logical channels, the UE follows the following priority order (arranged in order of priority from high to low) when performing logical channel priority processing:

1) Cell radio network temporary identifier (C-RNTI) MAC CE or data from the uplink common control channel (UL-CCCH);

2) Configured Grant Confirmation (Configured Grant Confirmation) MAC CE;

3) For BSR MAC CE except padding BSR;

4) Single Entry PHR MAC CE or Multiple Entry PHR MAC CE;

5) Data from any logical channel except UL-CCCH;

6) MAC CE for recommended bit rate query (Recommended bit rate query);

7) BSR MAC CE for padding buffer status report (padding BSR).

In the current NTN system, there is a large delay in wireless signal transmission between the terminal and the satellite. In the 3GPP NTN standardization process, the introduction of disabling the HARQ function is being discussed to reduce the data transmission delay, and it is agreed that the configuration of enabling or disabling the HARQ function can be based on the HARQ process. That is, for multiple HARQ processes of a terminal, it is possible to configure the HARQ function of some of the HARQ processes to be enabled, and the HARQ function of the other part of the HARQ process to be disabled.

If the HARQ function of a certain HARQ process is configured as disabled, on the one hand, the network can continue to schedule the HARQ process for data transmission without waiting to receive the uplink transmission of the UE (uplink data transmission for uplink HARQ, and ACK/NACK feedback from the UE for the downlink data transmission of the HARQ for downlink HARQ), thereby reducing the MAC transmission delay; on the other hand, if the network no longer schedules the HARQ process for retransmission, the reliability of MAC transmission will be affected.

Because different services have different QoS 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 configured as 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 configured as enabled can be used for transmission, thereby improving transmission reliability.

For downlink transmission, when scheduling resources, the network side equipment can allocate logical channels with different QoS requirements to different HARQ processes for transmission according to the QoS requirements of different logical channels. For uplink transmission, the current UL resource allocation is only allocated by the network side equipment based on the UE, and does not indicate which logical channels can use the allocated resources for transmission. However, according to the existing LCP, when the UE performs LCP on the received UL, it only considers the priority, and does not consider whether the resource corresponds to the feature of enabling/disabling the HARQ function. This may cause logical channels with different QoS requirements to be allocated to different HARQ processes, resulting in service transmission QoS cannot be guaranteed, resulting in a situation that violates the original intention of network resource allocation. The resource transmission is performed on the enabled HARQ process, and the information of the LCH2 is placed on the enabled HARQ process for resource transmission. Therefore, for the HARQ process with the HARQ function turned off and the HARQ process with the HARQ function turned on, how to complete uplink logical channel multiplexing needs to formulate a set of rules from the standard level.

It should be noted in advance that, in the embodiment of the present application, the HARQ process may or may not be configured with an enabled state. When the HARQ process is set to be enabled, based on the HARQ function, the HARQ process includes a HARQ process in a disabled state and a HARQ process in an enabled state. Enabling the HARQ function means that the HARQ process is in an enabled state, and disabling the HARQ function means that the HARQ process is in a disabled state. The HARQ process that is not configured with an enabled state can perform ACK/NACK feedback the same as the HARQ process with the HARQ function enabled. Of course, the HARQ process without an enabled state can also be a HARQ process that does not perform ACK/NACK feedback, which is not limited in this embodiment of the present application. In the following embodiments of the present application, the HARQ process without the HARQ function can also be understood as a HARQ process that does not limit the logical channel mapping situation, that is, according to the first information, any logical channel can send its corresponding uplink transmission on the HARQ process. The HARQ process in the disabled state and the HARQ process in the enabled state may be called two-attribute HARQ processes, or two types of HARQ processes.

The terminal may be a UE, and all embodiments of the present application use the terminal as a UE for illustration.

The terminal 01 and the satellite 02 are connected through a service link (service link), and the service link refers to a wireless link (radio link) between the terminal 01 and the satellite 02 .

13) An uplink CG index identifier, and a priority of at least one logical channel corresponding to the uplink CG index identifier. Wherein, the logical channel is the priority of the logical channel transmitted on the uplink CG resource corresponding to the uplink CG index identifier.

Configure CG resources and HARQ related parameters corresponding to the configured CG resources according to the received resource configuration signaling, and configure or determine the first logical channel and/or the second logical channel. The first logical channel includes a logical channel that allows transmission on a resource corresponding to the HARQ process in the disabled state, and the second logical channel includes a logical channel that prohibits transmission on the resource corresponding to the HARQ process in the disabled state, or Allows transmission on the resource corresponding to the HARQ process in the enabled state.

Step 302. According to the first information, send the uplink transmission corresponding to the first logical channel on the uplink resource.

Exemplarily, the RRC signaling used to configure the uplink CG resources may include RRC signaling used to configure type1 uplink CG resources, and may also include RRC signaling used to configure type2 uplink CG resources.

If the CG resource configured according to the RRC signaling is type1 CG, the UE can use the CG resource for data transmission after receiving the resource configuration signaling; if the configured CG resource is type2 CG, when the UE receives the resource configuration signaling and DCI signaling indicates activation, it can use the CG resource for data transmission.

In this embodiment of the present application, the first information may be at least one of the first item, the second item, and the fifth item to the twelfth item among the at least one information item described in step 301 above. The HARQ function of the HARQ process corresponding to the uplink CG resource may include three situations: the HARQ function is enabled, the HARQ function is disabled, and the HARQ function is not set. Therefore, step 302 can be divided into the following three situations:

In the first case, when the UE uses the CG resource for new transmission, if the UE determines, according to the first information, that the HARQ function corresponding to the uplink CG resource is in the disabled state, since the first logical channel is pre-set to include logical channels that allow transmission on resources corresponding to the HARQ process in the disabled state, the UE only maps the uplink data corresponding to the first logical information and/or at least the MAC CE corresponding to the first logical channel on the uplink CG resource.

In the second case, when the UE uses the CG resource for new transmission, if the UE determines that the HARQ function corresponding to the uplink CG resource is in the enabled state according to the first information, since the second logical channel is a logical channel that prohibits transmission on the resource corresponding to the HARQ process in the disabled state, or allows transmission on the resource corresponding to the HARQ process in the enabled state, then the UE only maps the uplink data corresponding to the second logical information and/or at least the MAC CE corresponding to the second logical channel to this Uplink CG resources.

In the third case, when the UE uses the CG resource for new transmission, if the UE determines according to the first information that the HARQ process corresponding to the uplink CG resource does not have the HARQ function configured, since the second logical channel is a logical channel that prohibits transmission on the resource corresponding to the HARQ process in the disabled state, or allows transmission on the resource corresponding to the HARQ process in the enabled state. on the uplink CG resource; or, the UE maps the uplink data corresponding to the first logical channel and the second logical channel and/or at least the MAC CE corresponding to the logical channel on the uplink CG resource.

It should be noted that, if the resource configuration information does not indicate the second logical channel, the UE may determine the second logical channel among all logical channels according to the first logical channel. Similarly, if the resource configuration information does not indicate the first logical channel, the UE may determine the first logical channel among all logical channels according to the second logical channel.

FIG. 4 shows a schematic diagram of a specific embodiment of the data transmission method described in FIG. 3 . It is assumed that the UE has established four uplink logical channels, namely LCH1, LCH2, LCH3 and LCH4. In this embodiment of the present application, description is made by taking an example in which the first information includes an identifier of a logical channel.

Step a1, the UE receives the resource configuration signaling sent by the network side device, and the UE configures the following content according to the resource configuration signaling:

Two sets of CG resources, respectively corresponding to CG index1 and CG index2, and both are type1 CG resources;

Among them, the two HARQ processes corresponding to the CG resources of CG index1, the corresponding HARQ IDs are 1 and 2 respectively, HARQ ID1 is configured as a disabled HARQ process, HARQ ID2 is configured as an enabled HARQ process, the LCHs that can be transmitted on CG index1 are LCH1 to LCH4, the first logical channel is configured as LCH1 and LCH2, and the second logical channel is identified as LCH3 and LCH4;

For the two HARQ processes corresponding to the CG resources of CG index2, the corresponding HARQ IDs are 3 and 4 respectively. Configure HARQ ID3 as a disabled HARQ process and HARQ ID4 as an enabled HARQ process. The LCHs that can be transmitted on CG index2 are LCH2 and LCH4. Configure the first logical channel as LCH2 and the second logical channel as LCH4.

Step a2. According to the first information, send the uplink transmission corresponding to the first logical channel on the uplink resource.

At time t1, the location of the CG resource of CG index1 is the corresponding HARQ process of HARQ ID1. At this time, each LCH has data to be transmitted. However, since HARQ ID1 is a disabled HARQ process and the first logical channel is identified as LCH1 and LCH2, the UE uses the uplink CG resource to transmit only the uplink data corresponding to LCH1 and LCH2. That is, the UE only transmits the uplink data corresponding to LCH1 and LCH2 on the uplink resource. send.

At time t2 is the position of the CG resource of CG index1, and the corresponding HARQ process is HARQ ID2. At this time, each LCH has data to be transmitted, but since HARQ ID2 is an enabled HARQ process and the second logical channel is identified as LCH3 and LCH4, the UE uses the uplink CG resource to transmit only the uplink data corresponding to LCH3 and LCH4, that is, the UE only transmits the uplink data corresponding to LCH3 and LCH4 on the uplink resource .

At the position of the CG resources at T3, the corresponding HARQ process is HARQ ID3. At this time, each LCH needs to be transmitted to the data. However, because the HARQ ID3 is the LCH2 and LCH4 transmitted by HARQ ID3 to the capable HARQ and the LCH transmission on CG Index2. That is, UE only sends the uplink data corresponding to LCH2 on the upward resource.

At time t4, the location of the CG resource of CG index2 corresponds to the HARQ process of HARQ ID4. At this time, each LCH has data to be transmitted. However, since HARQ ID4 is HARQ enabled and the LCHs transmitted on CG index2 are LCH2 and LCH4, the UE uses this uplink CG resource to transmit only the uplink data corresponding to LCH4, that is, the UE only transmits the uplink data corresponding to LCH4 on the uplink resource.

It should be noted that when the first information includes the uplink CG index identifier, the identifier and/or priority of at least one logical channel corresponding to the uplink CG index identifier, that is, the first information includes the CG index and the identifier and/or priority of the logical channel transmitted on the CG resource corresponding to the CG index. The identifier or priority of the LCH for transmission on the corresponding CG resource). Of course, this information can also be a kind of dedicated indication information and not carried in RRC.

It should also be noted that different CG resources may correspond to the same LCH ID, or may correspond to different LCH IDs. The LCHs corresponding to different CG resources may be the same type of logical channel. For example, different CG resources correspond to the first type of logical channel, or they may correspond to different types of logical channels. For example, one CG resource corresponds to the first logical channel, and another CG resource corresponds to the second logical channel.

Exemplarily, in the embodiment of the present application, the UE may correspond to CG resources and Dynamic Grant (Dynamic Grant, DG) resources, where the CG resources may correspond to at least one CG index, and each CG index may correspond to at least one HARQ process. When the UE is used as the granularity, the HARQ functions corresponding to at least one HARQ process corresponding to the UE can be all enabled or disabled; when the CG resource is used as the granularity, the HARQ functions corresponding to at least one HARQ process corresponding to the CG resources transmitted on at least one CG index can be all enabled or disabled; ARQ functions can be all enabled or all disabled; when the HARQ process is used as the granularity, the HARQ function of each HARQ process in at least one HARQ process corresponding to the CG resource needs to be configured separately.

When the granularity of UE, CG resource and CG index is used, the aforementioned first information may refer to any one of the first item, the second item, and the fifth item to the thirteenth item in step 301 .

For example, if the first information indicates that at least one HARQ process corresponding to the uplink resource whose CG index ID is A (A is a non-negative integer) is disabled, then only the uplink data corresponding to the first logical channel is transmitted on all uplink resources whose CG index ID is A (or its corresponding HARQ process).

In the first data transmission method, for different types of CG resources (that is, type1 and/or type2), the mapping relationship between LCH and HARQ processes with different HARQ functions is introduced into the RRC information to ensure that different LCHs are transmitted on the HARQ process with the HARQ function disabled and the HARQ process with the HARQ function enabled, thereby ensuring the QoS requirements of different services.

FIG. 5 shows a flow chart of the second data transmission method. In the data transmission method, the uplink resources include uplink CG resources (also referred to as CG resources, and the CG resources may be type 2CG).

The method includes:

Step 501: Receive a PDCCH.

The PDCCH is used to indicate the activation state of the uplink resource, and the PDCCH carries the first information. The first information may include at least one information item, and when the first information includes two or more information items, different information items may be carried in the same or different PDCCHs.

Exemplarily, before step 501, the data transmission method further includes: receiving resource configuration signaling of uplink resources. For example receive configuredgrantconfig IE. The resource configuration signaling is used to configure uplink type2 CG resources and corresponding HARQ related parameters. The resource configuration signaling may include at least one information item as follows:

1) Configure the CG index (index) identifier corresponding to the CG resource;

2) The number of HARQ processes corresponding to the configured CG resources. Exemplarily, when multiple CG resources are configured, HARQ offset is configured at the same time; Exemplarily, the number of HARQ processes corresponding to the configured CG resources includes: the number of HARQ processes corresponding to the configured CG index.

3) The HARQ process identifier corresponding to the configured CG resource; Exemplarily, the identifier of the HARQ process corresponding to the configured CG resource includes: the identifier of the HARQ process corresponding to the configured CG index.

Exemplarily, step 501 may include:

Step 501a, receiving DCI signaling carried by the PDCCH.

The DCI signaling carries first information, and the DCI signaling is used to activate uplink CG resources.

Step 501b, activate uplink CG resource according to DCI signaling.

When the UE receives the resource configuration signaling and receives the DCI signaling indicating to activate a certain uplink CG resource, it can use the uplink CG resource for data transmission.

Exemplarily, the first information may include at least one of the following information items:

1) Configure the CG index identifier corresponding to the CG resource;

2) The enabling status of all HARQ processes corresponding to the terminal;

3) The number of HARQ processes corresponding to the configured CG resources. Exemplarily, when multiple CG resources are configured, HARQ offset is configured at the same time; Exemplarily, the number of HARQ processes corresponding to the configured CG resources includes: the number of HARQ processes corresponding to the configured CG index.

4) The HARQ process identifier corresponding to the configured CG resource; Exemplarily, the identifier of the HARQ process corresponding to the configured CG resource includes: the identifier of the HARQ process corresponding to the configured CG index.

5) The enabling state of at least one HARQ process in the HARQ process corresponding to the configured CG resource; Exemplarily, including: a) The enabling state of all HARQ processes corresponding to the uplink CG resource; b) The enabling state of all HARQ processes corresponding to a single CG index identifier corresponding to the uplink CG resource, and the uplink CG resource corresponds to at least two CG index identifiers; c) The enabling state corresponding to a single HARQ process corresponding to the uplink CG resource.

6) The HARQ process identifier corresponding to the configured CG resource is disabled;

7) The enabled HARQ process identifier corresponding to the configured CG resource;

8) the identification of the first logical channel;

9) the priority of the first logical channel;

10) an identification of a second logical channel different from the first logical channel;

11) Differentiate the priority of the second logical channel from the first logical channel. The second logical channel is a logical channel that prohibits transmission on the resource corresponding to the HARQ process in the disabled state, or a logical channel that allows transmission on the resource corresponding to the HARQ process in the enabled state.

12) An uplink CG index identifier, and an identifier of at least one logical channel corresponding to the uplink CG index identifier. Wherein, the logical channel is the identifier of the logical channel transmitted on the uplink CG resource corresponding to the uplink CG index identifier.

13) The uplink CG index identifier, and the priority of at least one logical channel corresponding to the uplink CG index identifier. Wherein, the logical channel is the priority of the logical channel transmitted on the uplink CG resource corresponding to the uplink CG index identifier.

Exemplarily, the resource configuration signaling may include at least one information item in the first information. The resource configuration signaling and the PDCCH jointly provide complete first information.

Exemplarily, type2 CG resources and HARQ related parameters corresponding to the configured type2 CG resources are configured according to the received resource configuration signaling or DCI signaling, and the first logical channel and/or the second logical channel are configured or determined. The first logical channel includes a logical channel that is allowed to transmit on resources corresponding to the HARQ process in the disabled state, and the second logical channel is a logical channel that is prohibited from being transmitted on the resources corresponding to the HARQ process in the disabled state, or Allowed to transmit on the resources corresponding to the HARQ process in the enabled state.

Step 502. According to the first information, send the uplink transmission corresponding to the first logical channel on the uplink resource.

After the UE receives the PDCCH, the uplink CG resource can be activated according to the DCI signaling included therein. For the activated uplink CG resource, the UE may send the uplink transmission corresponding to the first logical channel on the uplink resource according to at least one information item in the foregoing first information. Similar to the above step 302, in the embodiment of the present application, the HARQ function of the HARQ process corresponding to the uplink CG resources may include three situations: the HARQ function is enabled, the HARQ function is disabled, and the HARQ function is not set. Therefore, step 302 can be divided into the following three situations:

In the first case, when the UE uses the CG resource for new transmission, if the UE determines that the HARQ function corresponding to the uplink CG resource is in the disabled state according to the first information, the UE only maps the uplink data corresponding to the first logical information and/or at least the MAC CE corresponding to the first logical channel to the uplink CG resource.

In the second case, when the UE uses the CG resource for new transmission, if the UE determines that the HARQ function corresponding to the uplink CG resource is enabled according to the first information, the UE only maps the uplink data corresponding to the first logical information and/or at least the MAC CE corresponding to the first logical channel to the uplink CG resource.

In the third case, when the UE uses the CG resource for new transmission, if the UE determines according to the first information that the HARQ process corresponding to the uplink CG resource does not have the HARQ function configured, the UE only maps the uplink data corresponding to the second logical information and/or at least the MAC CE corresponding to the second logical channel on the uplink CG resource; or, the UE maps the uplink data corresponding to the first logical channel and the second logical channel and/or at least the MAC CE corresponding to the logical channel on the uplink CG resource.

It should be noted that, if the DCI signaling does not indicate the second logical channel, the UE may determine the second logical channel among all logical channels according to the first logical channel. Similarly, if the first logical channel is not indicated in the DCI signaling, the UE may determine the first logical channel among all logical channels according to the second logical channel.

It should be noted that configuring the enabling state of the HARQ process, such as configuring the HARQ process HARQID1 corresponding to CG index1 as a disabled HARQ process, and HARQ ID2 as an enabled HARQ process, can also be configured in a dedicated RRC message or indicated in the DCI.

FIG. 6 shows a schematic diagram of a specific embodiment of the data transmission method described in FIG. 5 . It is assumed that the UE has established four uplink logical channels, namely LCH1, LCH2, LCH3 and LCH4.

Step b1, the UE receives the resource configuration signaling sent by the network side device, and the UE configures the following content according to at least one information item in the resource configuration signaling:

Two sets of CG resources correspond to CG index1 and CG index2 respectively, and both are CG resources of type2. The two HARQ processes corresponding to the CG resources of CGindex1 have corresponding HARQ IDs 1 and 2 respectively. For the two HARQ processes corresponding to the CG resource of CG index2, the corresponding HARQ IDs are 3 and 4 respectively, and HARQ ID3 is configured as a disabled HARQ process, and HARQ ID4 is an enabled HARQ process.

In step b2, the UE receives the PDCCH carrying the DCI instruction.

The first information in the DCI signaling indicates activation of the CG resource of CG index 1, and the process may include: first, the DCI signaling indicates activation of the CG resource of CG index 1; then the first information in the DCI signaling indicates that in the HARQ process corresponding to the CG resource of CG index 1, there is a disabled HARQ process.

Further, it indicates that HARQ ID1 is a disabled HARQ process, and HARQ ID2 is an enabled HARQ process. Indicates that the LCHs that can be transmitted on CG index1 are LCH1, LCH2, and LCH3. Indicates that the ID of the first logical channel is LCH1, LCH2, and the ID of the second logical channel is LCH3, LCH4.

Further, the dedicated RRC message or the DCI may indicate the identification and/or priority of the logical channel transmitted on the CG resource corresponding to at least one CG index, for example, the LCHs that can be transmitted on the CG index1 are LCH1, LCH2 and LCH3, which can be used to limit the identification and/or priority of the LCH transmitted on a certain HARQ process or on each CG resource (such as the CG resource corresponding to a specific CG index). Correspondingly, the information may be one of the first information, or a special indication information.

It should be noted that since the CG resource of CG index2 does not indicate activation (so it is not shown in FIG. 6 ), the UE cannot use the CG resource for UL transmission. Until later, when the UE receives an instruction from the network to activate the resource of the CG index2, the UE can use the resource of the CG index2 for transmission.

As another embodiment, configuring the enabling state of the HARQ process, such as configuring the HARQ process HARQ ID1 corresponding to CG index1 as a disabled HARQ process, and HARQ ID2 as an enabled HARQ process, may also be configured in a dedicated RRC message or indicated in the DCI.

Exemplarily, the enabling state of the HARQ process may be determined according to information such as the number of HARQ processes, the priority of the LCH, the priority of data corresponding to the LCH, and the established service QoS.

Step b3. According to the first information, send the uplink transmission corresponding to the first logical channel on the uplink resource.

At time t1, the position of the CG resource of CG index1, the corresponding HARQ process is HARQ ID1, and each LCH has data to be transmitted at this time, but since HARQ ID1 is a disabled HARQ process and the first logical channel is identified as LCH1 and LCH2, the UE uses this uplink CG resource to only transmit uplink data of LCH1 and LCH2.

At time t2, it is the position of the CG resource of CG index1, and the corresponding HARQ process is HARQ ID2. At this time, each LCH has data to be transmitted, but since HARQ ID2 is an enabled HARQ process and the second logical channel is identified as LCH3 and LCH4, but LCH4 cannot be transmitted on the resource of CG index1, the UE uses the uplink CG resource to transmit only the uplink data of LCH3.

Exemplarily, the first information carried in the DCI may include an uplink CG index identifier, an identifier and/or priority of at least one logical channel corresponding to the uplink CG index identifier, for example, the LCHs that can be transmitted on the CG index1 are LCH1, LCH2 and LCH3, which can be used to limit the identifier or priority of the LCH that is transmitted on a certain HARQ process or on each CG resource (such as the CG resource corresponding to a specific CG index). In addition, the uplink CG index identifier, the identifier and/or priority of at least one logical channel corresponding to the uplink CG index identifier may be indicated in dedicated indication information, for example, indicated in a dedicated RRC message.

It should also be noted that different CG resources may correspond to the same LCH ID, or may correspond to different LCH IDs. The LCHs corresponding to different CG resources may be the same type of logical channel. For example, different CG resources correspond to the first type of logical channel, or they may correspond to different types of logical channels. For example, one CG resource corresponds to the first logical channel, and another CG resource corresponds to the second logical channel.

Exemplarily, the UE may correspond to CG resources and DG resources, where the CG resources may correspond to at least one CG index, and each CG index may correspond to at least one HARQ process. When the UE is used as the granularity, the HARQ functions corresponding to at least one HARQ process corresponding to the UE can be all enabled or disabled; when the CG resource is used as the granularity, the HARQ functions corresponding to at least one HARQ process corresponding to the CG resources transmitted on at least one CG index can be all enabled or disabled; ARQ functions can be all enabled or all disabled; when the HARQ process is used as the granularity, the HARQ function of each HARQ process in at least one HARQ process corresponding to the CG resource needs to be configured separately.

When UE, CG resource and CG index are used as granularity, the foregoing first information may include at least one information item in the first information described in step 501 .

For example, if the first information indicates that at least one HARQ process corresponding to the uplink resource whose CG index ID is A (A is a non-negative integer) is disabled, then only the uplink data corresponding to the first logical channel is transmitted on all uplink resources whose CG index ID is A (or its corresponding HARQ process).

In the second data transmission method, for type2 CG resources, the DCI signaling introduces the mapping relationship between LCH and HARQ processes with different HARQ functions, ensuring that different LCHs are transmitted on the HARQ process with the HARQ function disabled and the HARQ process with the HARQ function enabled, thereby ensuring the QoS requirements of different services.

FIG. 7 shows a flow chart of the third data transmission method. In the data transmission method, the uplink resources include DG resources, and one DG resource corresponds to one HARQ process. The method includes:

Step 701: Receive resource scheduling signaling of uplink resources.

The resource scheduling signaling carries first information, and the resource scheduling signaling includes downlink control information DCI signaling for scheduling uplink dynamic resources. The resource scheduling signaling may include PDCCH.

The resource scheduling signaling carries first information. The resource scheduling signaling includes at least one information item. The first information may include at least one information item. When the first information includes two or more information items, different information items are carried in the same or different resource scheduling signaling. The following shows at least one information item that may be included in the resource scheduling signaling:

1) The HARQ process identifier corresponding to the configured DG resource;

2) The enabling state of the HARQ process corresponding to the configured DG resource;

3) the identification of the first logical channel;

4) the priority of the first logical channel;

5) an identification of the second logical channel that is different from the first logical channel;

6) The priority of the second logical channel that is different from the first logical channel, where the second logical channel is a logical channel that prohibits transmission on resources corresponding to the HARQ process in the disabled state, or allows transmission on the resources corresponding to the HARQ process in the enabled state; logical channel;

7) An identifier of at least one logical channel corresponding to the configured DG resource. Wherein, at least one logical channel corresponding to the configured DG resource refers to a logical channel transmitted on the DG resource.

8) The priority of at least one logical channel corresponding to the configured DG resource. Wherein, at least one logical channel corresponding to the configured DG resource refers to a logical channel transmitted on the DG resource.

It should be noted that if the DCI indicates that the HARQ function of the HARQ process is in the disabled state, then the DCI indicates information about the first logical channel; if the DCI indicates that the HARQ function of the HARQ process is in the disabled state, then the DCI indicates information about the second logical channel. In other possible implementation manners, if the DCI signaling indicates that the HARQ function of the HARQ process is in the disabled state, and the DCI signaling also indicates the second logical channel, the UE may first determine the first logical channel among all logical channels according to the second logical channel indicated by the DCI signaling, and then transmit the uplink data corresponding to the first logical channel on the HARQ process in the disabled state. Alternatively, if the DCI signaling indicates that the HARQ function of the HARQ process is in a disabled state, the UE may indicate the logical channel corresponding to the HARQ process and identify the logical channel as the first logical channel. This embodiment of the present application does not limit this.

Step 702: Send the uplink transmission corresponding to the first logical channel on the uplink resource according to the first information.

If the network indicates that the resource is a new transmission resource through the DCI or the new indication information (New Data Indication, NDI) is reversed (0 becomes 1, or 1 becomes 0), the UE can use the DG resource for new transmission. Otherwise, the UE retransmits the transmission using the DG resource process.

In this embodiment of the present application, the first information may be at least one of items 2 to 6 in at least one information item included in the resource configuration signaling. For the three cases of the HARQ function of the HARQ process corresponding to the DG resource, step 702 may include the following three cases:

In the first case, if it is a new transmission resource, when the UE uses the DG resource for new transmission, if the UE determines, according to the first information, that the HARQ function corresponding to the uplink DG resource is in the disabled state, then the UE only maps the uplink data corresponding to the first logical information and/or at least the MAC CE corresponding to the first logical channel to the uplink CG resource.

In the second case, if it is a new transmission resource, when the UE uses the DG resource for new transmission, if the UE determines that the HARQ function corresponding to the uplink DG resource is enabled according to the first information, the UE only maps the uplink data corresponding to the second logical information and/or at least the MAC CE of the second logical channel to the UL CG resource.

In the third case, if it is a new transmission resource, when the UE uses the DG resource for new transmission, if the UE determines according to the first information that the HARQ process corresponding to the uplink DG resource does not have the HARQ function configured, then the UE only maps the uplink data corresponding to the second logical information and/or at least the MAC CE corresponding to the second logical channel on the uplink CG resource; or, the UE maps the uplink data corresponding to the first logical channel and the second logical information and/or at least the MAC CE corresponding to the logical channel on the uplink CG resources.

It should be noted that, if the DCI does not indicate the second logical channel, the UE may determine the second logical channel among all logical channels according to the first logical channel. Similarly, if the first logical channel is not indicated in the DCI, the UE may determine the first logical channel among all logical channels according to the second logical channel.

FIG. 8 shows a schematic diagram of a specific embodiment of the data transmission method described in FIG. 7 . It is assumed that the UE has established four uplink logical channels, namely LCH1, LCH2, LCH3 and LCH4.

Step c1, the UE receives the DCI indication information sent by the network side equipment, and schedules DG resources for new transmission. At the same time, the information indicated in the DCI specifically includes:

1) The HARQ process identifier corresponding to the DG resource is HARQ ID1;

2) Indicating that the HARQ ID1 is a disabled HARQ process, that is, indicating the attribute of the HARQ process type (ie, the enabling status of the HARQ process).

3) Indicating that the first logical channel is identified as LCH1 and LCH2, that is, information about the first logical channel.

4) Indicating that the LCHs that can be transmitted on the resource are LCH1, LCH2 and LCH3, that is, the attributes of the LCHs that can be transmitted on the DG resource.

Step c2. According to the first information, send the uplink transmission corresponding to the first logical channel on the uplink resource.

For the DG resource, at this time, each LCH has data to be transmitted that can be transmitted. However, since the LCHs that can be transmitted on this resource are indicated as LCH1, LCH2, and LCH3, only the data of LCH1, LCH2, and LCH3 can be transmitted on this DG. At the same time, the type of the HARQ process, the type indicated by the HARQ process whose ID is 1 is a disabled HARQ process, and the first logical channel is identified as LCH1 and LCH2, then the UE uses the DG resource to transmit only data of LCH1 and LCH2.

It should be noted that the UE may also first determine the attribute of the HARQ process type and the first logical channel information, and then determine the attribute of the indicated LCH that can be transmitted on the DG resource, or simultaneously determine the attribute of the HARQ process type, the first logical channel information, and the indicated attribute of the LCH that can be transmitted on the resource, or perform determination in other order, which is not limited in this embodiment of the present application.

It should also be noted that in the third data transmission method, the resource scheduling signaling may also be called resource transmission signaling or other signaling names, and the signaling is used to allocate uplink resources, and this application does not limit the specific name of the signaling.

In the third data transmission method, for DG resources, a mapping relationship between LCHs and HARQ processes with different types of HARQ functions is introduced into the DCI to ensure that different LCHs are transmitted on the HARQ processes with the HARQ function disabled and the HARQ processes with the HARQ function enabled, thereby ensuring the QoS requirements of different services.

It should be noted that, in the above three data transmission methods, after the terminal sends the uplink transmission corresponding to the first logical channel on the uplink resource according to the first information, the terminal then multiplexes the uplink data corresponding to the first logical channel, and/or, at least the MAC CE corresponding to the first logical channel on the uplink resource, so as to ensure the QoS requirements of different services during the transmission process.

In summary, the data transmission method provided by the embodiment of the present application can send the uplink transmission corresponding to the first logical channel corresponding to the HARQ process in the disabled state on the resource corresponding to the HARQ process in the disabled state according to the first information, so that the terminal can send the uplink transmission corresponding to the LCH on the appropriate uplink resource according to the correspondence between the LCH and different types of HARQ processes, thereby ensuring the QoS requirements of different services.

FIG. 9 shows a flow chart of a data transmission method provided by an embodiment of the present application. The method can be applied to a network side device, such as the satellite 02 in the implementation environment shown in FIG. 1 . The method includes:
