Description

Configuration method of hybrid automatic repeat request mode and related device
Technical Field
The present invention relates to the field of wireless communications, and in particular, to a method and a related apparatus for configuring a hybrid automatic repeat request mode.
Background
In a 4G/5G wireless communication system, a Hybrid Automatic Repeat Request (HARQ) technology can efficiently compensate for errors caused by link adaptation, improve data transmission rate, and reduce data transmission delay, and thus has very general application.
A terminal (User Equipment, UE) sends a data Control request through Medium Access Control (MAC), where the MAC is used to support HARQ. The HARQ of MAC uses two mode types, distinguished by the time when retransmission occurs: a Synchronous HARQ (Synchronous HARQ) mode and an Asynchronous HARQ (Asynchronous HARQ) mode. The synchronous HARQ mode is that the transmission (retransmission) of one HARQ process occurs at a fixed time, and because the receiving end knows the transmission time in advance, the receiving end does not need additional signaling overhead to identify the serial number of the HARQ process, and the serial number of the HARQ process at the moment can be obtained from a subframe number, the mode has simple control signaling, can save the overhead of control information in a system, but the sending and feedback time points of each process are fixed, and have insufficient flexibility; the asynchronous HARQ mode refers to that transmission (retransmission) of one HARQ process can occur at any time, and the receiving end does not know the occurrence time of the transmission in advance, so the processing sequence number of the HARQ process needs to be sent together with data. With the increasing variety of wireless services, it is increasingly difficult for a single fixed HARQ mode type to meet complex data transmission requirements. On this basis, hybrid-HARQ (H-HARQ) schemes supporting a mixture of multiple HARQ mode types are gradually emerging in the art.
However, how the access network device configures a suitable HARQ mode for the terminal in multiple HARQ mode types becomes one of the technical problems that needs to be solved urgently in the art.

Detailed Description
The invention is explained in more detail below with reference to the drawings and exemplary embodiments.
In the hybrid HARQ scheme, for the uplink HARQ, there are four values in the HARQ mode, which are: a synchronous HARQ mode, an asynchronous HARQ mode, a synchronous and asynchronous HARQ entity hybrid mode, and a synchronous and asynchronous HARQ process hybrid mode; for downlink HARQ, there are also four values for the HARQ mode, which are: a synchronous HARQ mode, an asynchronous HARQ mode, a mixed mode of synchronous and asynchronous HARQ entities, a mixed mode of synchronous and asynchronous HARQ processes; wherein, the first and the second end of the pipe are connected with each other,
synchronous HARQ mode, which means that the transmission (retransmission) of one HARQ process occurs at a fixed time;
asynchronous HARQ mode, meaning that the transmission (retransmission) of one HARQ process can occur at any time;
the hybrid mode of synchronous and asynchronous HARQ entities means that a user has the HARQ entities of the types of synchronous HARQ entity and asynchronous HARQ entity, etc. at the same time, but only one HARQ entity works at the same time point when the hybrid mode is used;
the hybrid mode of synchronous and asynchronous HARQ processes means that a user has one HARQ entity, and different processes of the HARQ entity can transmit data and receive feedback in a synchronous manner or transmit data and receive feedback in an asynchronous manner.
In practical applications, the HARQ mode used by the UE is configured by Radio Resource Control (RRC) signaling. When the HARQ mode configuration is carried out, the HARQ mode configuration information of MAC is added in RRC signaling, the HARQ mode used by a user in one cell or cell group is indicated, and the HARQ mode is sent to the UE through establishment or reconfiguration of RRC connection. Therefore, a mechanism is needed for RRC to select a suitable HARQ mode for the UE.
Based on this, the embodiment of the present invention provides a method for configuring a hybrid automatic repeat request mode. Fig. 1 is a flowchart illustrating a configuration method of a hybrid automatic repeat request mode according to an embodiment of the present invention; as shown in fig. 1, the method comprises the steps of:
step 101: the access network equipment configures an HARQ mode for the terminal based on at least one of capability information, quality of Service (QoS) information and network load information of the terminal; the HARQ mode includes at least one of: synchronous HARQ mode, asynchronous HARQ mode, synchronous and asynchronous HARQ entity hybrid mode, synchronous and asynchronous HARQ process hybrid mode.
The access network device configures an HARQ mode for the terminal, and specifically may configure an HARQ mode for the terminal by an RRC layer in the access network device, and the configured HARQ mode is, for example, a HARQ mode set, where the HARQ mode set includes one or more HARQ modes; and dynamically scheduling the configured HARQ mode set by the MAC layer.
The capability of the terminal (UE category) information may include an indication of HARQ mode capabilities supported by the terminal. Specifically, an HARQ mode capability indication that can be supported by the terminal is newly added to a capability parameter of the terminal, and then the access network device determines a first group of HARQ modes supported by the terminal based on the HARQ mode capability indication supported by the terminal.
In an embodiment, before the access network device configures an HARQ mode for the terminal based on at least one of capability information, qoS information, and network load information of the terminal, the method further includes: the access network equipment acquires the stored capability information of the terminal; or, the access network device obtains the capability information of the terminal from a core network device.
It can be understood that, if the access network device stores the capability information of the terminal, the access network device (specifically, RRC) uses the capability information; otherwise, the access network device applies for the capability parameter configuration of the terminal to a core network device to obtain the capability information of the terminal.
The QoS information may include information such as transmission delay, transmission time interval, guaranteed Bit Rate (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 an HARQ mode for the terminal based on at least one of capability information, qoS information, and network load information of the terminal, the method further includes: and the access network equipment acquires initial QoS information configured for the terminal by core network equipment.
The network load information may include an air interface load, a configuration ratio of an uplink timing sequence and a downlink timing sequence, and the like. Through the network load information, the access network device (specifically, the RRC) obtains the minimum QoS requirement and the maximum QoS requirement threshold of the service that can be supported by the current cell.
In an embodiment, before the access network device configures an HARQ mode for the terminal based on at least one of capability information, qoS information, and network load information of the terminal, the method further includes: and the access network equipment acquires the network load information of the cell where the current user is located.
In a specific embodiment, the configuring, by the access network device, an HARQ mode for the terminal based on at least one of capability information, qoS information, and network load information of the terminal includes: the access network equipment determines a first group of HARQ modes supported by the terminal based on the capability information of the terminal; determining to configure HARQ modes for the terminal from the first set of HARQ modes based on the QoS information and/or network load information.
The first group of HARQ modes can be specifically divided into a first group of uplink HARQ modes and a first group of downlink HARQ modes according to uplink and downlink processes; the first group of uplink HARQ modes and the first group of downlink HARQ modes can respectively comprise all or part of a synchronous HARQ mode, an asynchronous HARQ mode, a synchronous and asynchronous HARQ entity hybrid mode and a synchronous and asynchronous HARQ process hybrid mode.
The determining to configure HARQ mode for the terminal from the first set of HARQ modes based on the QoS information and/or network load information comprises at least one of:
determining a HARQ mode based on transmission delay in the QoS information; wherein the transmission delay is lower than a first preset threshold and corresponds to a synchronous HARQ mode and/or an asynchronous HARQ mode, and the transmission delay is higher than the first preset threshold and corresponds to a synchronous and asynchronous HARQ entity hybrid mode and/or a synchronous and asynchronous HARQ process hybrid mode;
determining an HARQ mode based on an air interface load in the network load information; wherein the air interface load is higher than a second preset threshold and corresponds to at least one of a synchronous HARQ mode, a synchronous and asynchronous HARQ entity hybrid mode and a synchronous and asynchronous HARQ process hybrid mode;
determining an HARQ mode based on the configuration proportion of the uplink time sequence and the downlink time sequence in the network load information; the configuration ratio of the uplink time sequence to the downlink time sequence exceeds a preset range and corresponds to at least one of an asynchronous HARQ mode, a synchronous and asynchronous HARQ entity hybrid mode and a synchronous and asynchronous HARQ process hybrid mode.
In an aspect, the QoS information may specifically include transmission delay as one of selection conditions for configuring the HARQ mode for the terminal by the access network device. The transmission delay in the QoS information may specifically be a receiving and sending delay of a service of a user to a data packet at an air interface. When the transmission delay is lower than a first preset threshold, the requirement of the service on the transmission delay of the data packet is higher; for example, voice services generally require real-time transmission, and transmission delay is as low as possible, so that the receiving and transmitting success rate is high and the retransmission probability is low; 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 transmission delay being lower than a first preset threshold corresponds to a synchronous HARQ mode; at this time, the configured HARQ mode can both meet the transmission requirement and reduce the complexity of the transmission process (the hybrid mode of synchronous and asynchronous HARQ entity/process can increase the complexity of the user process). Conversely, when the transmission delay is higher than a first preset threshold, it indicates that the requirement of the service on the transmission delay of the data packet is low; for example, in a network video playing service, since a video to be watched can be cached, the requirement on transmission delay is not high, but the retransmission probability is high; at this time, the access network device configures a synchronous and asynchronous HARQ entity hybrid mode and/or a synchronous and asynchronous HARQ process hybrid mode for the terminal from the first group of HARQ modes, so as to more flexibly perform data transmission and processing.
In an optional embodiment of the present invention, the determining that the transmission delay is lower than the first preset threshold corresponds to a synchronous HARQ mode and/or an asynchronous HARQ mode includes: the transmission time delay is lower than a first preset threshold, and the transmission time interval between adjacent data packets meets a first preset condition and corresponds to a synchronous HARQ mode; the transmission delay is lower than a first preset threshold and the transmission time interval between adjacent data packets does not meet a first preset condition, and the transmission time interval corresponds to an asynchronous HARQ mode.
The condition that the transmission time interval between the adjacent data packets satisfies the first preset condition may specifically include that the transmission time interval between the adjacent data packets has a regular pattern. For example, the transmission time interval between adjacent data packets is 20ms (milliseconds), and at this time, the access network device configures the HARQ mode for the terminal as the synchronous HARQ mode. On the contrary, if there is no regularity in the transmission time interval between adjacent data packets at the time of retransmission, the asynchronous HARQ mode is configured.
In an optional embodiment of the present invention, the determining that the transmission delay is higher than the first preset threshold corresponds to a hybrid mode of synchronous and asynchronous HARQ entities and/or a hybrid mode of synchronous and asynchronous HARQ processes includes: the transmission delay is higher than a first preset threshold and corresponds to a synchronous and asynchronous HARQ entity hybrid mode and/or a synchronous and asynchronous HARQ process hybrid mode under the condition that the bit rate GBR meets a second preset condition; the synchronous HARQ entity and the asynchronous HARQ entity in the synchronous and asynchronous HARQ entity mixed mode are both used; both synchronous and asynchronous modes on each process of the HARQ entity in the hybrid mode of synchronous and asynchronous HARQ processes are used.
The GBR satisfies a second predetermined condition, for example, the GBR is required by the traffic of the user, that is, the required bit rate can be maintained even when the network resources are short.
On the other hand, as another selection condition for configuring the HARQ mode for the terminal by the access network device, the network load information according to the embodiment of the present invention may specifically include an air interface load and/or a configuration ratio of an uplink timing sequence and a downlink timing sequence.
The air interface load may specifically be a control channel utilization rate; due to the fact that the asynchronous HARQ mode has a large degree of dependence on the control channel, when the utilization rate of the control channel exceeds a preset threshold, other HARQ modes (namely at least one of a synchronous HARQ mode, a synchronous and asynchronous HARQ entity hybrid mode and a synchronous and asynchronous HARQ process hybrid mode) except the asynchronous HARQ mode are determined from the first group of HARQ modes as the HARQ modes configured to the terminal. And when the control channel utilization rate does not exceed the preset threshold, no further selection can be made in the first group of HARQ modes.
It should be understood that, when the determining that the HARQ mode is configured for the terminal from the first set of HARQ modes based on the QoS information and/or the network load information is determining the HARQ mode based on the transmission delay in the QoS information and the air interface load in the network load information, that is, when the selection condition for configuring the HARQ mode for the terminal by the access network device 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 an intersection of HARQ modes corresponding to the selection condition. For example, the determining, by the access network device, the first group of HARQ modes supported by the terminal based on the capability information of the terminal includes: a synchronous HARQ mode, an asynchronous HARQ mode, a synchronous and asynchronous HARQ entity hybrid mode, and a synchronous and asynchronous HARQ process hybrid mode; the access network device further determines whether transmission delay in the QoS information is lower than a first preset threshold, and determines a second group of HARQ modes from the first group of HARQ modes when the transmission delay is lower than the first preset threshold, where the second group of HARQ modes includes: a synchronous HARQ mode and an asynchronous HARQ mode; the access network device further determines whether an air interface load in the network load information is higher than a second preset threshold, and when the air interface load is higher than the second preset threshold, selects another HARQ mode except the asynchronous HARQ mode from the second group of HARQ modes to form a third group of HARQ modes, where the third group of HARQ modes specifically includes: synchronizing HARQ modes, and finally configuring the third group of HARQ modes to the terminal; and when the air interface load is not higher than a second preset threshold, configuring the second group of HARQ modes to the terminal. Alternatively, when the transmission delay is higher than a 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: a synchronous and asynchronous HARQ entity hybrid mode and a synchronous and asynchronous HARQ process hybrid mode; at this time, if the air interface load in the network load information is higher than a second preset threshold, selecting another HARQ mode from the fourth group of HARQ modes except the asynchronous HARQ mode to form a fifth group of HARQ modes, where the fifth group of HARQ modes specifically includes: a synchronous and asynchronous HARQ entity hybrid mode and a synchronous and asynchronous HARQ process hybrid mode, and finally configuring the fifth group of HARQ modes to the terminal; and when the air interface load is not higher than a second preset threshold, configuring the fourth group of HARQ modes to the terminal.
The configuration ratio of the uplink timing sequence and the downlink timing sequence exceeding a preset range specifically means 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 uplink timing and the downlink timing are configured with serious deviation, that is, the timing conflict between the uplink and downlink data transmission and the corresponding downlink and uplink feedback is serious. For example, in Time Division Duplex (TDD), downlink received information is more, and uplink feedback information is less, so that a ratio of uplink timing to downlink timing configuration exceeds a preset range; at this time, other HARQ modes (i.e., at least one of an asynchronous HARQ mode, a synchronous and asynchronous HARQ entity hybrid mode, and a synchronous and asynchronous HARQ process hybrid mode) than the synchronous HARQ mode are determined from the first group of HARQ modes as HARQ modes configured to the terminal. And when the configuration ratio of the uplink timing sequence to the downlink timing sequence does not exceed the preset range, no further selection can be made in the first group of HARQ modes.
It should be understood that, when the determining, based on the QoS information and/or the network load information, to configure the HARQ mode for the terminal from the first set of HARQ modes includes determining HARQ modes based on two or more of transmission delay in the QoS information, air interface load in the network load information, and a configuration ratio of uplink timing and downlink timing in the network load information, an HARQ mode finally configured for the terminal should be an intersection of HARQ modes corresponding to the selection conditions.
In an optional embodiment of the present invention, the idle load higher than the second preset threshold corresponds to at least one of a synchronous HARQ mode, a synchronous and asynchronous HARQ entity hybrid mode, and a synchronous and asynchronous HARQ process hybrid mode, and includes: the air interface load is higher than the second preset threshold and corresponds to at least one of a synchronous HARQ mode, a synchronous functional part in a mixed mode of synchronous and asynchronous HARQ entities and a synchronous functional part in a mixed mode of synchronous and asynchronous HARQ processes.
In an optional embodiment of the present invention, the ratio of the uplink timing and the downlink timing configuration exceeding the preset range corresponds to at least one of an asynchronous HARQ mode, a hybrid mode of synchronous and asynchronous HARQ entities, and a hybrid mode of synchronous and asynchronous HARQ processes, and includes: the configuration ratio of the uplink time sequence to the downlink time sequence exceeds a preset range and corresponds to at least one of an asynchronous HARQ mode, an asynchronous functional part in a synchronous and asynchronous HARQ entity hybrid mode and an asynchronous functional part in a synchronous and asynchronous HARQ process hybrid mode.
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 the uplink timing sequence and the downlink timing sequence in the network load information, which may specifically be a HARQ mode selected for a terminal by an MAC layer in access network equipment.
Referring to fig. 1, in an embodiment, the method further includes:
step 102: and the access network equipment sends the configured HARQ mode to the terminal.
In an embodiment, the sending, by the access network device, the configured HARQ mode to the terminal includes: and the access network equipment sends a Radio Resource Control (RRC) signaling to the terminal, wherein the RRC signaling comprises a hybrid automatic repeat request (HARQ) mode configured for the terminal.
It can be understood that the HARQ mode configured for the terminal may be used to indicate a HARQ mode used by the terminal in one cell or a cell group, so that the terminal performs uplink and/or downlink HARQ data transmission using the HARQ mode.
In an embodiment, the method further comprises: and the access network equipment adjusts 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 sub-layer on a Radio Access Network (RAN) including RRC already has the relevant information of the user. And on the basis that the access network equipment configures the HARQ mode for the terminal based on at least one of the capability information, the QoS information and the network load information of the terminal, the step 101 is executed again based on the updated QoS information and/or the network load information to configure the updated HARQ mode for the terminal.
The QoS information may be obtained by self-learning in the Service Data reception and transmission process through a Service Data Adaptation Protocol (SDAP)/Packet Data Convergence Protocol (PDCP)/Radio Link Control (RLC) Protocol; the obtained QoS information is, for example, qoS parameters actually used by the service on the RAN side. And the SDAP/PDCP/RLC sends the obtained QoS information to RRC. Specifically, because the Data transceiving between the core network device and the access network device is based on the mapping from QoS flow (QoS flow) to Data Radio Bearer (DRB), the QoS parameter on each DRB may be self-learned according to the QoS parameter of the QoS flow of the Bearer. The SDAP/PDCP/RLC can send the self-learned QoS parameters of the DRB-based service to the RRC for judging the service QoS requirement.
The network load information can be obtained by monitoring an air interface in real time in the scheduling process of the MAC; and the MAC sends the obtained network load information to RRC. Specifically, when the MAC schedules each Transmission Time Interval (TTI), the usage rate of the control channel and the configuration ratio of the uplink timing and the downlink timing of the air interface may be obtained, and the MAC may provide an optimization scheme request for the HARQ mode used by the user according to the actual scheduling condition of the air interface.
In an optional embodiment, the obtaining updated QoS information specifically includes: and when the QoS information changes, acquiring updated QoS information.
In an optional embodiment, the obtaining updated network load information specifically includes: and when the network load information meets a second preset condition, obtaining updated network load information. The second preset condition is that at least one of the load of the control channel, the number of times of timing relationship conflicts, and the number of scheduling objects included in each scheduling priority exceeds a preset threshold value during scheduling.
Fig. 2 is a schematic diagram illustrating a relationship between a measurement input and a signaling output of a HARQ mode configuration method according to an embodiment of the present invention. As shown in the figure, the RRC in the access Network device receives capability information of a terminal from a Core Network (CN) device, qoS information of an SDAP/PDCP/RLC, and Network load information of an MAC, configures an HARQ mode for the terminal based on at least one of the above information, and outputs signaling for a base station gNB and a terminal UE.
In the embodiment of the present invention, the configuration method of the harq mode may be applied to a 5G communication system; accordingly, the access network device may 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 requirement, the access network device may change the available HARQ mode for the terminal.
The technical solution of the present invention is further described in detail by the following specific examples.
For convenience of description, the different HARQ modes are numbered separately as follows:
for uplink HARQ, there are four values for the HARQ mode:
1A: synchronizing HARQ;
1B: asynchronous HARQ;
1C: a mix of synchronous and asynchronous HARQ entities;
1D: mixing synchronous and asynchronous HARQ processes;
for downlink HARQ, there are four values for the HARQ mode:
2A: synchronizing HARQ;
2B: asynchronous HARQ;
2C: mixing synchronous and asynchronous HARQ entities;
2D: the synchronous and asynchronous HARQ processes are mixed.
First, an indication of HARQ mode capability that the UE can support is newly added in a 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 establishes, 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 an initial QoS parameter of the service of the user to the access network device (in this embodiment, specifically, an RRC layer of the access network device, which is represented by an RRC below); for the capability information of the terminal, if the RRC stores the capability parameter of the UE, the RRC uses the parameter, otherwise, the capability parameter configuration of the UE is applied to the core network equipment; for the network load information, the RRC acquires the network load of the cell where the current user is located, and through the load index, the RRC acquires the lowest QoS requirement and the highest QoS requirement threshold of the service which can be supported by the current cell.
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 comprises at least one of the following: the utilization rate of the control channel/the idle rate of the control channel, the utilization rate of the air interface wireless resource and the efficiency of the air interface wireless resource for bearing bit data. The cell load of the higher layer radio resource management comprises at least one of: the number of users, the average minimum service guarantee rate, the average maximum service guarantee rate, and the average value of the time difference of two times of scheduling of the users.
The configuring of the HARQ mode for the terminal based on at least one of the above information specifically includes the following steps:
firstly, determining an uplink and downlink HARQ (hybrid automatic repeat request) capability set which can be supported by the UE according to the capability information of the UE;
secondly, further determining a HARQ capability set according to the QoS information of the service; in particular, the amount of the solvent to be used,
if the receiving and sending delay (i.e. transmission delay) requirement of the service on the data packet in the air interface is lower than a threshold value (such as 1 ms), using a mode (also called a single mode) of 1A/1B and 2A/2B types;
further, if the receiving and sending delay requirement of the service on the data packet at the air interface is lower than a threshold value and the time interval between two adjacent data packets is regular, 1A and 2A type modes are used; if the receiving and sending time delay requirement of the service on the data packet at the air interface is lower than a threshold value and no rule exists in the time interval between two adjacent data packets, the 1B and 2B type modes are used;
if the receiving and sending delay of the service on the air interface is required to be higher than a threshold value (such as 1 ms), a mode of 1C/1D and 2C/2D types (also called a mixed mode) is used;
further, if the receiving and sending delay requirement of the service on the data packet at the air interface is higher than a threshold value and the service requires a certain guaranteed bit rate, the synchronous part and the asynchronous part in the 1C/1D mode and the 2C/2D mode are selected to be used;
thirdly, further determining a HARQ capability set according to the network load; in particular, the amount of the solvent to be used,
if the air interface load exceeds a threshold value (for example, the control channel utilization rate exceeds 70%), using modes of 1A/1C/1D and 2A/2C/2D types;
and if the air interface load is lower than a threshold value (for example, the control channel utilization rate is lower than 70%), taking the result selected according to the capability information of the UE and the QoS information of the service as the HARQ mode set of the user.
Further, if the air interface load exceeds a threshold, the mode using the 1A/1C/1D and 2A/2C/2D types may specifically be to use a synchronization function part in 1A or 1C/1D and a synchronization function part in 2A or 2C/2D; for example, when the control channel for several consecutive TTIs is insufficient, the MAC may choose to let the user use 1A/2A (i.e. synchronous HARQ) mode, or the synchronous function part in 1C/2C, 1D/2D;
if the configuration proportion of the uplink time sequence and the downlink time sequence exceeds a preset range, using 1B/1C/1D and 2B/2C/2D type modes, specifically using an asynchronous function part in 1B or 1C/1D and an asynchronous function part in 2B or 2C/2D; for example, when the timing collision between the uplink and downlink data transmission and the corresponding downlink and uplink feedback is severe, the MAC may choose to let the user use the 1B/2B (i.e., asynchronous HARQ) mode, or the asynchronous functional part in 1C/2C and 1D/2D.
It should be noted that when the available HARQ set of the RRC-configured user cannot meet the scheduling requirement of the MAC, the MAC may report that the RRC requires to change the available HARQ mode set of the user.
Finally, the determined HARQ mode set is configured to the terminal in user-established RRC signaling (such as RRC connection establishment signaling).
Next, when reconfiguring the user, on the basis of a user uplink and downlink HARQ mode set determined by the capability information of the UE, the service QoS information of the user, and the network load information of the current cell, reporting, by the SDAP/PDCP/RLC, a QoS parameter actually used by the service on the RAN side, which is obtained by self-learning in the service data transceiving process, and a condition that the MAC monitors the air interface in real time in the scheduling process to the RRC, and respectively correcting the HARQ mode by the RRC; and finally updating the HARQ mode set actually available for the user.
Finally, for the QoS information report of SDAP/PDCP/RLC, a change, namely a report mode can be adopted; namely, when the QoS parameter of the DRB self-learned by the SDAP/PDCP/RLC changes, the QoS parameter is immediately reported to the RRC. For the network load information reported by the MAC, a reporting mode can be adopted when the network load information exceeds a threshold; for example, different thresholds are set for the load of the control channel, the number of times of timing relationship conflicts, the number of scheduling objects included in each scheduling priority during scheduling, and the like, respectively, and when the thresholds are met, the MAC side reports to the RRC.
