Description

A configuration method and related device for hybrid automatic repeat request mode

technical field

The present invention relates to the field of wireless communication, in particular to a method for configuring a hybrid automatic repeat request mode and a related device.

Background technique

In 4G/5G wireless communication systems, Hybrid Automatic Repeat Request (HARQ) technology can efficiently compensate for bit errors caused by link adaptation, improve data transmission rates, and reduce data transmission delays , so it has very general application.

A terminal (User Equipment, UE) sends a data control request through a medium access control (Medium Access Control, MAC), and the MAC is used to support HARQ. According to the time at which retransmission occurs, the HARQ of the MAC uses two types of modes: synchronous HARQ (Synchronous HARQ) mode and asynchronous HARQ (Asynchronous HARQ) mode. Among them, the synchronous HARQ mode means that the transmission (retransmission) of a HARQ process occurs at a fixed time. Since the receiving end knows the transmission time in advance, no additional signaling overhead is required to identify the serial number of the HARQ process. At this time, the HARQ The serial number of the process can be obtained from the subframe number. This mode of control signaling is simple and can save the overhead of control information in the system, but the sending and feedback time points of each process are fixed, and the flexibility is not enough; the asynchronous HARQ mode refers to The transmission (retransmission) of a HARQ process can occur at any time, and the receiving end does not know the time when the transmission occurs in advance, so the processing sequence number of the HARQ process needs to be sent together with the data. This mode is more flexible to use, but requires complex path signaling. As the types of wireless services continue to increase, it becomes increasingly difficult for a single fixed HARQ mode type to meet complex data transmission requirements. On this basis, a hybrid HARQ (Hybrid-HARQ, H-HARQ) scheme supporting multiple types of HARQ modes gradually appears in the field.

However, how an access network device configures a suitable HARQ mode for a terminal among various types of HARQ modes has become one of technical problems urgently to be solved in this field.

Detailed ways

The present invention will be described in further detail below with reference to the accompanying drawings and specific embodiments.

In the hybrid HARQ scheme, for the uplink HARQ, the HARQ mode has four values, which are: synchronous HARQ mode, asynchronous HARQ mode, synchronous and asynchronous HARQ entity mixed mode, synchronous and asynchronous HARQ process mixed mode; for downlink HARQ, The HARQ mode also has four values, which are: synchronous HARQ mode, asynchronous HARQ mode, synchronous and asynchronous HARQ entity mixed mode, synchronous and asynchronous HARQ process mixed mode; among them,

Synchronous HARQ mode means that the transmission (retransmission) of a HARQ process occurs at a fixed time;

Asynchronous HARQ mode, which means that the transmission (retransmission) of a HARQ process can occur at any time;

The synchronous and asynchronous HARQ entity mixed mode means that the user has both synchronous HARQ entity and asynchronous HARQ entity and other types of HARQ entities, but when using it, only one HARQ entity is working at the same time point;

Synchronous and asynchronous HARQ process mixed mode means that the user has a HARQ entity, and different processes of the HARQ entity can use a synchronous method to send data and receive feedback, or use an asynchronous method to send data and feedback reception.

In practical applications, the HARQ mode used by the UE is configured by radio resource control (Radio Resource Control, RRC) signaling. When configuring the HARQ mode, add MAC HARQ mode configuration information in RRC signaling to indicate the HARQ mode used by the user in a cell or cell group, and send it to the UE through RRC connection establishment or reconfiguration. Therefore, a mechanism for RRC to select an appropriate HARQ mode for UE is needed.

Based on this, an embodiment of the present invention provides a method for configuring a hybrid automatic repeat request mode. Fig. 1 is a schematic flow chart of a method for configuring a hybrid automatic repeat request mode provided by an embodiment of the present invention; as shown in Fig. 1 , the method includes the following steps:

Step 101: The access network device configures a HARQ mode for the terminal based on at least one of terminal capability information, Quality of Service (QoS) information, and network load information; the HARQ mode includes at least one of the following: synchronous HARQ mode, asynchronous HARQ mode, synchronous and asynchronous HARQ entity mixed mode, synchronous and asynchronous HARQ process mixed mode.

Wherein, the access network device configures the HARQ mode for the terminal, specifically, the RRC layer in the access network device configures the HARQ mode for the terminal, and the configured HARQ mode is, for example, a HARQ mode set, and the HARQ mode set includes a One or more of the HARQ modes; the MAC layer dynamically schedules in the configured HARQ mode set.

The capability (UE category) information of the terminal may include a capability indication of the HARQ mode supported by the terminal. Specifically, the HARQ mode capability indication that the terminal can support is newly added to the capability parameter of the terminal, and then, the access network device determines the first group of HARQ modes supported by the terminal based on the HARQ mode capability indication supported by the terminal. model.

In an embodiment, before the access network device configures the HARQ mode for the terminal based on at least one of terminal capability information, QoS information, and network load information, the method further includes: the access network device obtains The stored capability information of the terminal; or, the access network device obtains the capability information of the terminal from a core network device.

Understandably, if the capability information of the terminal is stored in the access network device, the access network device (specifically, RRC) uses the information; otherwise, the access network device applies to the core network device for the Configure the capability parameter of the terminal to obtain the capability information of the terminal.

The QoS information may include information such as transmission delay, transmission time interval, guaranteed bit rate (Guarantee BitRate, GBR), and may also include information such as available bandwidth, throughput, delay variation (jitter and drift), and loss.

In an embodiment, before the access network device configures the HARQ mode for the terminal based on at least one of terminal capability information, QoS information, and network load information, the method further includes: the access network device obtains Initial QoS information configured by the core network device for the terminal.

The network load information may include air interface load, configuration ratio of uplink timing and downlink timing, and the like. Through the above network load information, the access network device (specifically, RRC) obtains the minimum QoS requirement and the highest QoS requirement threshold of the services supported by the current cell.

In an embodiment, before the access network device configures the HARQ mode for the terminal based on at least one of terminal capability information, QoS information, and network load information, the method further includes: the access network device obtains The network load information of the cell where the current user is located.

In a specific embodiment, the access network device configures the HARQ mode for the terminal based on at least one of the terminal's capability information, QoS information, and network load information, including: the access network device configures the HARQ mode for the terminal based on the terminal's The capability information determines the first group of HARQ modes supported by the terminal; and determines to configure the HARQ mode for the terminal from the first group of HARQ modes based on the QoS information and/or network load information.

The first group of HARQ modes can be specifically divided into the first group of uplink HARQ modes and the first group of downlink HARQ modes according to the uplink and downlink processes; the first group of uplink HARQ modes and the first group of downlink HARQ modes can be respectively It includes all or part of the synchronous HARQ mode, the asynchronous HARQ mode, the synchronous and asynchronous HARQ entity mixed mode, and the synchronous and asynchronous HARQ process mixed mode.

The determining to configure the HARQ mode for the terminal from the first group of HARQ modes based on the QoS information and/or network load information includes at least one of the following:

Determine the HARQ mode based on the transmission delay in the QoS information; wherein, the transmission delay lower than the first preset threshold corresponds to a synchronous HARQ mode and/or an asynchronous HARQ mode, and the transmission delay is higher than the first preset threshold A preset threshold corresponds to a synchronous and asynchronous HARQ entity mixed mode and/or a synchronous and asynchronous HARQ process mixed mode;

Determine the HARQ mode based on the air interface load in the network load information; wherein, the air interface load is higher than the second preset threshold corresponding to the synchronous HARQ mode, the synchronous and asynchronous HARQ entity mixed mode, and the synchronous and asynchronous HARQ process mixed mode at least one of

Determine the HARQ mode based on the configuration ratio of uplink timing and downlink timing in the network load information; wherein, the configuration ratio of uplink timing and downlink timing exceeds a preset range and corresponds to asynchronous HARQ mode, synchronous and asynchronous HARQ entity mixed mode, and synchronous and at least one of the mixed modes of the asynchronous HARQ process.

On the one hand, as one of the selection conditions for the access network device to configure the HARQ mode for the terminal, the QoS information may specifically include transmission delay. Wherein, the transmission delay in the QoS information may specifically be the sending and receiving delay of the user's service to the data packet on the air interface. When the transmission delay is lower than the first preset threshold, it indicates that the service has higher requirements on the transmission delay of the data packet; for example, the voice service, the general voice service requires real-time transmission, and the transmission delay is as low as possible. Furthermore, the success rate of transceiving is high, and the probability of retransmission is small; at this time, the access network device configures a synchronous HARQ mode and/or an asynchronous HARQ mode for the terminal from the first group of HARQ modes; optionally, the A transmission delay lower than the first preset threshold corresponds to a synchronous HARQ mode; at this time, the configured HARQ mode can meet the transmission requirements while reducing the complexity of transmission processing (the synchronous and asynchronous HARQ entity/process mixed modes will increase the complexity of user processing). On the contrary, when the transmission delay is higher than the first preset threshold, it indicates that the service has lower requirements on the transmission delay of data packets; The delay requirement is not high, but the retransmission probability is relatively high; at this time, the access network device configures a synchronous and asynchronous HARQ entity mixed mode and/or a synchronous and asynchronous HARQ mode for the terminal from the first group of HARQ modes Process mixed mode, so that data transmission and processing can be performed more flexibly.

In an optional embodiment of the present invention, the transmission delay lower than the first preset threshold corresponds to the synchronous HARQ mode and/or the asynchronous HARQ mode, including: the transmission delay is lower than the first preset threshold and corresponds to The transmission time interval between adjacent data packets meets the first preset condition corresponding to the synchronous HARQ mode; the transmission delay is lower than the first preset threshold and the transmission time interval between adjacent data packets does not meet the first preset condition The conditions correspond to asynchronous HARQ mode.

The transmission time interval between adjacent data packets meeting the first preset condition may specifically include that there is a rule in the transmission time interval between adjacent data packets. For example, the transmission time interval between adjacent data packets is 20 ms (milliseconds), at this time, the access network device configures the HARQ mode for the terminal as a synchronous HARQ mode. On the contrary, if there is no regular transmission time interval between adjacent data packets during retransmission, the asynchronous HARQ mode is configured.

In an optional embodiment of the present invention, the transmission delay higher than the first preset threshold corresponds to a synchronous and asynchronous HARQ entity mixed mode and/or a synchronous and asynchronous HARQ process mixed mode, including: the transmission time When the extension is higher than the first preset threshold and the bit rate GBR is guaranteed to meet the second preset condition, it corresponds to a synchronous and asynchronous HARQ entity mixed mode and/or a synchronous and asynchronous HARQ process mixed mode; the synchronous and asynchronous HARQ entity mixed Both the synchronous HARQ entity and the asynchronous HARQ entity are used in the mode; the synchronous mode and the asynchronous mode on each process of the HARQ entity in the synchronous and asynchronous HARQ process mixed mode are used.

The GBR satisfies the second preset condition. For example, the user's service has certain requirements on the GBR, that is, the required bit rate can be maintained even when network resources are tight.

On the other hand, as another selection condition for the access network device to configure the HARQ mode for the terminal, the network load information in the embodiment of the present invention may specifically include air interface load and/or configuration ratio of uplink timing and downlink timing.

Wherein, the air interface load may specifically be the utilization rate of the control channel; since the asynchronous HARQ mode is highly dependent on the control channel, when the utilization rate of the control channel exceeds the preset threshold, the asynchronous HARQ mode shall be determined from the first group of HARQ modes. Other HARQ modes (that is, at least one of the synchronous HARQ mode, the synchronous and asynchronous HARQ entity mixed mode, and the synchronous and asynchronous HARQ process mixed mode) other than the HARQ mode are used as the HARQ mode configured for the terminal. However, when the control channel usage rate does not exceed the preset threshold, further selection may not be performed in the first group of HARQ modes.

It should be understood that when it is determined from the first group of HARQ modes based on the QoS information and/or network load information that the HARQ mode configured for the terminal is based on the transmission delay in the QoS information and the network load The air interface load in the information determines the HARQ mode, that is, when the selection condition of the HARQ mode configured by the access network device for the terminal includes both the transmission delay in the QoS information and the air interface load in the network load information , the HARQ mode finally configured for the terminal should be the intersection of the HARQ modes corresponding to the above selection conditions. For example, the access network device determines, based on the capability information of the terminal, that the first group of HARQ modes supported by the terminal includes: synchronous HARQ mode, asynchronous HARQ mode, synchronous and asynchronous HARQ entity mixed mode, and synchronous and asynchronous HARQ process Mixed mode: the access network device further judges whether the transmission delay in the QoS information is lower than a first preset threshold, and when the transmission delay is lower than the first preset threshold, the first A second group of HARQ modes is determined in the group of HARQ modes, and the second group of HARQ modes includes: a synchronous HARQ mode and an asynchronous HARQ mode; the access network device further determines whether the air interface load in the network load information is higher than the second A preset threshold, when the load of the air interface is higher than the second preset threshold, select a HARQ mode other than the asynchronous HARQ mode from the second group of HARQ modes to form a third group of HARQ modes, and the third group of HARQ modes The modes specifically include: a synchronous HARQ mode, and finally configure the third group of HARQ modes to the terminal; when the air interface load is not higher than a second preset threshold, configure the second group of HARQ modes to the terminal. As another case, when the transmission delay is higher than the first preset threshold, a fourth group of HARQ modes is determined from the first group of HARQ modes, and the fourth group of HARQ modes includes: synchronous and asynchronous HARQ entity mixed mode and synchronous and asynchronous HARQ process mixed mode; at this time, if the air interface load in the network load information is higher than the second preset threshold, select asynchronous HARQ from the fourth group of HARQ modes Other HARQ modes other than the HARQ mode constitute the fifth group of HARQ modes, and the fifth group of HARQ modes specifically include: a synchronous and asynchronous HARQ entity mixed mode and a synchronous and asynchronous HARQ process mixed mode, and finally configure the fifth group of HARQ modes For the terminal; when the air interface load is not higher than the second preset threshold, configure the fourth group of HARQ modes for the terminal.

The configuration ratio of the uplink timing and downlink timing exceeding the preset range may specifically mean that the configuration ratio is lower than the lowest value of the preset range, or the configuration ratio is higher than the highest value of the preset range; at this time, The configuration deviation between uplink timing and downlink timing is serious, that is, the timing conflict between uplink and downlink data transmission and corresponding downlink and uplink feedback is serious. For example, in time division duplexing (Time Division Duplexing, TDD), there are more downlink received information, but less uplink feedback information, so the configuration ratio of uplink timing and downlink timing may exceed the preset range; at this time, from all In the first group of HARQ modes, other HARQ modes (that is, at least one of the asynchronous HARQ mode, the synchronous and asynchronous HARQ entity mixed mode, and the synchronous and asynchronous HARQ process mixed mode) other than the synchronous HARQ mode are determined as configurations for the described The HARQ mode of the terminal. And when the configuration ratio of the uplink timing to the downlink timing does not exceed the preset range, further selection may not be performed in the first group of HARQ modes.

It should be understood that when determining to configure the HARQ mode for the terminal from the first group of HARQ modes based on the QoS information and/or network load information, including based on the transmission delay in the QoS information, the network When two or more of the air interface load in the load information and the configuration ratio of uplink timing and downlink timing in the network load information determine the HARQ mode, the HARQ mode finally configured for the terminal should be the HARQ mode corresponding to the above selection conditions intersection.

In an optional embodiment of the present invention, the air interface load higher than the second preset threshold corresponds to at least one of a synchronous HARQ mode, a synchronous and asynchronous HARQ entity mixed mode, and a synchronous and asynchronous HARQ process mixed mode, including : The air interface load higher than the second preset threshold corresponds to at least one of the synchronous HARQ mode, the synchronous function part in the synchronous and asynchronous HARQ entity mixed mode, and the synchronous function part in the synchronous and asynchronous HARQ process mixed mode.

In an optional embodiment of the present invention, the configuration ratio of uplink timing and downlink timing exceeding a preset range corresponds to at least one of asynchronous HARQ mode, synchronous and asynchronous HARQ entity mixed mode, and synchronous and asynchronous HARQ process mixed mode , including: the configuration ratio of the uplink timing to the downlink timing exceeds a preset range corresponding to the asynchronous HARQ mode, the asynchronous function part in the synchronous and asynchronous HARQ entity mixed mode, and the asynchronous function part in the synchronous and asynchronous HARQ process mixed mode at least one.

Wherein, the HARQ mode is determined based on the air interface load in the network load information, and/or the HARQ mode is determined based on the configuration ratio of uplink timing and downlink timing in the network load information, which may specifically be a The MAC layer selects the HARQ mode for the terminal.

Please continue to refer to Figure 1, in one embodiment, the method also includes:

Step 102: the access network device sends the configured HARQ mode to the terminal.

In an embodiment, the access network device sending the configured HARQ mode to the terminal includes: the access network device sending radio resource control RRC signaling to the terminal, the RRC signaling includes the HARQ mode configured for the terminal.

It can be understood that the HARQ mode configured for the terminal may be used to indicate the HARQ mode used by the terminal in a cell or cell group, so that the terminal uses the HARQ mode to perform uplink and/or downlink HARQ data transmission.

In an embodiment, the method further includes: the access network device adjusting the QoS information and/or the network load information to obtain updated QoS information and/or network load information.

It can be understood that when the user is reconfigured, the user is already running, and each protocol sublayer on the radio access network (Radio Access Network, RAN) including the RRC already has information about the user. On the basis that the access network device configures the HARQ mode for the terminal based on at least one of the terminal's capability information, QoS information, and network load information, the step is performed again based on the updated QoS information and/or network load information 101. Configure an updated HARQ mode for the terminal.

Wherein, the QoS information may be received in the service data through the service data adaptation protocol (Service Data Adaptation Protocol, SDAP)/packet data convergence protocol (Packet Data Convergence Protocol, PDCP)/radio link layer control (Radio Link Control, RLC) protocol The obtained QoS information is, for example, the QoS parameter actually used by the service on the RAN side. The SDAP/PDCP/RLC sends the obtained QoS information to the RRC. Specifically, because the data sent and received between the core network device and the access network device is based on the mapping from the QoS flow (QoSflow) to the data radio bearer (Data Radio Bearer, DRB), the QoS parameters on each DRB can be based on the QoS flow of the bearer QoS parameters for self-learning. The SDAP/PDCP/RLC may send the self-learned QoS parameters of the DRB-based service to the RRC to judge the service QoS requirement.

The network load information can be obtained through the real-time monitoring of the air interface by the MAC during the scheduling process; the MAC sends the obtained network load information to the RRC. Specifically, when the MAC schedules each transmission time interval (TransmissionTime Interval, TTI), it can obtain the utilization rate of the control channel, the configuration ratio of the uplink timing of the air interface and the configuration ratio of the downlink timing, and the MAC can calculate the HARQ used by the user according to the actual scheduling situation of the air interface. Mode gives an optimization solution request.

In an optional embodiment, the obtaining updated QoS information specifically includes: obtaining updated QoS information when the QoS information changes.

In an optional embodiment, the obtaining updated network load information specifically includes: obtaining updated network load information when the network load information satisfies a second preset condition. Wherein, the second preset condition is, for example, that at least one of the load of the control channel, the number of timing relationship conflicts, and the number of scheduling objects included in each scheduling priority exceeds a preset threshold value during scheduling.

Fig. 2 shows a schematic diagram of the relationship between the measurement input and the signaling output of the HARQ mode configuration method provided by a specific embodiment of the present invention. As shown in the figure, the RRC in the access network device receives the capability information of the terminal from the core network (Core Network, CN) device, the QoS information of SDAP/PDCP/RLC, and the network load information of MAC, and based on the above At least one type of information in the information configures the HARQ mode for the terminal, and outputs signaling for the base station gNB and the terminal UE.

In the embodiment of the present invention, the method for configuring the HARQ mode can be applied to a 5G communication system; correspondingly, the access network device can be a gNB.

It should be noted that when the HARQ mode configured by the access network device for the terminal cannot meet the scheduling requirements, the access network device may change the available HARQ mode for the terminal.

The technical solution of the present invention will be further described in detail through specific examples below.

For the convenience of description, the different HARQ modes are numbered as follows:

For uplink HARQ, the HARQ mode has four values:

1A: synchronous HARQ;

1B: asynchronous HARQ;

1C: Mixed synchronous and asynchronous HARQ entities;

1D: Mixed synchronous and asynchronous HARQ processes;

For downlink HARQ, the HARQ mode has four values:

2A: synchronous HARQ;

2B: Asynchronous HARQ;

2C: Hybrid of synchronous and asynchronous HARQ entities;

2D: Mixed synchronous and asynchronous HARQ processes.

Firstly, a capability indication of the HARQ mode supported by the UE is newly added in the capability parameter of the UE. Specifically, the uplink HAQR capability set includes all or part of 1A, 1B, 1C, and 1D; the downlink HARQ capability set includes part or all of 2A, 2B, 2C, and 2D.

Next, when the user is established, the capability information, QoS information and network load information of the terminal are obtained, and the HARQ mode is configured for the terminal based on at least one of the above information.

Specifically, for the QoS information, the core network device configures the initial QoS parameters of the user's service for the access network device (specifically, the RRC layer of the access network device in this embodiment, hereinafter represented by RRC); information, if RRC itself stores the UE’s capability parameter, RRC uses this parameter, otherwise it applies to the core network equipment for UE’s capability parameter configuration; for network load information, RRC obtains the network load of the cell where the current user is located, and through this load index, The RRC acquires the minimum QoS requirement and the highest QoS requirement threshold of the services supported by the current cell.

Wherein, the network load information may include an air interface load and a cell load of a high-level radio resource management (RRM). The air interface load includes at least one of the following: control channel usage rate/control channel idle ratio, air interface wireless resource usage rate, and air interface wireless resource carrying bit data efficiency. The cell load of the high-level radio resource management includes at least one of the following: the number of users, the average minimum service guaranteed rate, the average maximum service guaranteed rate, and the average value of the time difference between two scheduled users.

The configuring the HARQ mode for the terminal based on at least one of the above information specifically includes the following steps:

First, according to the capability information of the UE, determine the uplink and downlink HARQ capability sets that the UE can support;

Secondly, according to the QoS information of the service, further determine the HARQ capability set; specifically,

If the service requires that the transmission and reception delay (transmission delay) of data packets on the air interface be lower than the threshold value (such as 1ms), then use the 1A/1B and 2A/2B types of modes (also called single mode);

Further, if the service requires that the transmission and reception delay of data packets on the air interface is lower than the threshold value and the time interval between two adjacent data packets is regular, then use the 1A and 2A types of modes; if the service requires data If the transmission and reception delay of packets on the air interface is lower than the threshold and the time interval between two adjacent data packets is not regular, then use 1B and 2B types of modes;

If the service requires that the transmission and reception delay of data packets on the air interface is higher than the threshold value (such as 1ms), then use the 1C/1D and 2C/2D types of modes (also called mixed modes);

Further, if the service requires that the transmission and reception delay of data packets on the air interface is higher than the threshold value and the service requires a certain guaranteed bit rate, then select both the synchronous and asynchronous parts in the 1C/1D and 2C/2D modes to be used ;

Again, according to the network load, further determine the HARQ capability set; specifically,

If the air interface load exceeds the threshold value (for example, the control channel usage rate exceeds 70%), use 1A/1C/1D and 2A/2C/2D types of modes;

If the load of the air interface is lower than the threshold value (for example, the utilization rate of the control channel is lower than 70%), the HARQ mode set of the user is selected according to the UE capability information and the service QoS information.

Further, if the air interface load exceeds the threshold value, the mode of using 1A/1C/1D and 2A/2C/2D types may be specifically using the synchronization function part in 1A or 1C/1D, and the synchronization function in 2A or 2C/2D The synchronization function part; for example, when the control channel of several consecutive TTIs is insufficient, the MAC can choose to let the user use the 1A/2A (that is, synchronous HARQ) mode, or the synchronization function part in 1C/2C, 1D/2D;

If the configuration ratio of uplink timing to downlink timing exceeds the preset range, use 1B/1C/1D and 2B/2C/2D types of modes, specifically, use the asynchronous function part in 1B or 1C/1D, and 2B or The asynchronous function part in 2C/2D; for example, when the timing conflict between uplink and downlink data transmission and its corresponding downlink and uplink feedback is serious, MAC can choose to allow users to use 1B/2B (that is, asynchronous HARQ) mode, or 1C/2B Asynchronous function part in 2C, 1D/2D.

It should be noted that when the user's available HARQ set configured by the RRC cannot meet the scheduling requirements of the MAC, the MAC may report to the RRC to request to change the user's available HARQ mode set.

Finally, configure the determined HARQ mode set to the terminal in the RRC signaling established by the user (such as RRC connection establishment signaling).

Next, when reconfiguring the user, RRC uses SDAP/PDCP/RLC on the basis of the user's uplink and downlink HARQ mode set determined by UE capability information, user service QoS information, and current cell network load information. The QoS parameters actually used by the service on the RAN side and the real-time monitoring of the air interface by the MAC during the scheduling process obtained through self-learning during the service data transmission and reception process are reported to the RRC, and the RRC respectively corrects the HARQ mode; finally updates the user’s actual available A set of HARQ modes.

Finally, for the QoS information reporting of SDAP/PDCP/RLC, the method of reporting upon change can be adopted; that is, when the QoS parameters of the DRB self-learned by SDAP/PDCP/RLC change, they are immediately reported to RRC. For the network load information reported by the MAC, it can be reported when it exceeds the threshold; for example, different thresholds are set for the load of the control channel, the number of timing relationship conflicts, and the number of scheduling objects included in each scheduling priority during scheduling. When the threshold is met, the MAC side reports to RRC.
