Description

Information transmission method, configuration optimization method, device, terminal and network equipment

Technical Field

The present invention relates to the field of communications technologies, and in particular, to an information transmission method, a configuration optimization method, an apparatus, a terminal, and a network device.

Background

The small data transmission is divided into two transmission modes, one is small data transmission (Small data transmission, SDT) based on Configuration Grant (CG), namely CG-SDT, and the other is small data transmission based on Random Access (RA), namely RA-SDT. The terminal, or User Equipment (UE), preferably selects the CG-SDT, and if the CG-SDT selection condition cannot be satisfied, the UE selects the RA-SDT. When RA-SDT is selected, SDT of two-step random access (2-step RACH) is selected preferentially, and when the condition is not satisfied, SDT of four-step random access (4-step RACH) is selected.

Based on the existing SDT transmission scheme, the terminal performs SDT selection according to the SDT configuration of the network equipment side, and determines the SDT transmission mode, so that after the network equipment side configures the configuration information of the SDT for the UE, the problem that the UE can not meet the SDT access condition all the time possibly exists, thereby causing resource waste.

The following is a brief introduction to the SDT process:

the small data transmission is divided into two transmission modes, one is CG-SDT and the other is RA-SDT. The specific selection process is as follows:

step 1: the UE performs uplink carrier selection, determining whether the selected carrier is a supplementary uplink (Supplementary Uplink, SUL).

Step 2: the UE performs SDT selection on the corresponding carrier.

Step 3: if the CG-SDT criteria can be met, the UE selects the CG-SDT mode to trigger the SDT procedure.

Step 4: if the CG-SDT criteria cannot be met, the UE selects the RA-SDT mode to trigger the SDT procedure.

The method for triggering the SDT by the UE in the RA-SDT mode specifically comprises the following steps:

step 4a: the SDT procedure of the 2-step RACH is preferentially selected;

step 4b: if the 2-step RACH cannot be satisfied, then the SDT procedure of the 4-setp RACH is selected.

Wherein the UE may trigger CG-SDT conditions including:

(1) The size of the data packet to be transmitted is smaller than or equal to a predefined threshold value;

(2) The reference signal received power (Reference Signal Received Power, RSRP) is greater than or equal to a predefined threshold value.

The conditions under which the UE may trigger RA-SDT include:

(1) The size of the data packet to be transmitted is smaller than or equal to a predefined threshold value

(2) RSRP is greater than or equal to the configured threshold.

(3) The selection of 2-step RACH or 4-step RACH may be based on existing rules.

Wherein the random access channel resources (Random Access Channel, RACH) resources are different for RA between RA-SDT and non-SDT (non-SDT), the random access resource criteria for RA-SDT include:

if the SDT and non-SDT differ in RO, no preamble partitioning is required (preamble partitioning);

preamble partitioning is required if the RO of SDT and non-SDT are the same.

The following is a brief introduction for a random access procedure:

1. four-step random access process:

as shown in fig. 1, the four-step random access is classified into contention and non-contention random access. The SDT of the 4-step RA is a contention-based random access procedure. The contention-based random access procedure is as follows:

step 1: the terminal sends MSG1 to the network equipment (such as gNB) and transmits a random access preamble;

step 2: the terminal receives the MSG2 sent by the network device, and receives a random access response (Random Access Response, RAR), where the terminal carries an uplink grant (UL grant) for transmitting the MSG 3.

Step 3: the terminal sends MSG3 to the network equipment and sends uplink scheduling transmission;

step 4: the terminal receives MSG4 sent by the network equipment, and the competition is solved;

If the competition is resolved, the four-step random access process is completed

2. Two-step random access process:

as shown in fig. 2, the two-step random access is classified into a contention and a non-contention random access, and the contention-based random access procedure is as follows:

step 1: the terminal transmits the MSGA, a transmission random access preamble and a physical uplink shared channel (Physical uplink shared channel, PUSCH) payload (payload) to a network device (e.g., gNB).

Step 2: and the terminal receives the MSGB sent by the network equipment and solves the competition.

If a successful random access response (success RAR) is received, the 2-step RA procedure is completed; if a fallback random access response (fallback rar) is received, the fallback to the 4-step RA procedure is performed, as shown in fig. 3.

step 4: the terminal receives the Msg4 of the network device and resolves the contention.

Wherein, the two-step random access and the four-step random access are selected as follows: if the network equipment side is configured with two-step random access and four-step random access resources, two-step random access and four-step random access are selected through configured thresholds, such as an RSRP Threshold (msgA-RSRP-Threshold) of msgA; if the measured signal quality is above msgA-RSRP-Threshold, a two-step random access procedure is selected, and if the measured signal quality is below msgA-RSRP-Threshold, a four-step random access procedure is selected.

The RACH report may include the following: for random access purposes, cell identity, random access frequency related information and access synchronization signal block (Synchronization Signal block, SSB) RSRP measurement quantity, etc.

For CG-SDT, the network needs to configure special CG resource for UE, and the CG resource is only applicable to the cell configuring CG for the connected UE at the network equipment side. When the UE accesses the network, selecting appropriate resources of the beam level on the CG resources according to the pre-configured CG resources, and sending an UL data packet. CG resources in CG-SDT may also be UE level resources, depending on the network implementation.

From the view of network optimization technology, the optimization mechanism related to RA is that the UE can report the information of the latest RA access process, including the random access purpose, the number of RA accesses when successful, SSB resource information when each RA attempt, whether the information is changed from 2-step RA to 4-step RA after 2-step RA reaches the maximum transmission number, whether the information is returned to 4-step RA after 2-step RA acquires the back-off indication, and the like. However, these RA information reporting procedures cannot be used to optimize CG resources, as the objects of optimization are not identical.

The network equipment side can judge that CG resources are unavailable according to the phenomenon that the UE has CG capability and is configured with CG resources related to SDT, but the UE accesses the network or transmits data of the SDT through other non-CG access modes without using the CG resources. However, the information is too general, the network cannot judge that the UE does not use CG resources, and therefore the CG resources cannot be optimized effectively, if the CG resources aiming at the SDT are not optimized, the UE is likely to not meet the condition of CG-SDT access all the time, the CG resources configured at the network equipment side are wasted, and the UE cannot enjoy the advantages of low power consumption and short time delay of the CG-SDT flow. Furthermore, the optimization of RA for RA-SDT procedures is not satisfactory for efficient work based solely on existing RA reporting mechanisms.

The embodiment of the application provides an information transmission method, a configuration optimization method, a device, a terminal and network equipment, so as to solve the problem that CG resources cannot be effectively optimized due to the fact that a scheme for optimizing related configuration of CG-SDT is not available at present, and therefore CG resources are wasted; and based on the existing RA reporting mechanism, the optimization of RA-SDT related configuration and RA related configuration cannot be met, and the problems that resources are wasted and effective work cannot be met are also possible.

The method and the apparatus (or the terminal or the network device) are based on the same application, and because the principles of the method and the apparatus (or the terminal or the network device) for solving the problem are similar, the implementation of the apparatus (or the terminal or the network device) and the method can be referred to each other, and the repetition is omitted.

As shown in fig. 4, an embodiment of the present invention provides an information transmission method, which specifically includes the following steps:

step 41: the terminal receives SDT configuration information sent by the network equipment, wherein the SDT configuration information comprises CG configuration information for SDT.

Optionally, the step 41 may include the terminal receiving CG configuration information for SDT in a connected state, or receiving CG configuration information for SDT in a SDT transmission process, which is not limited to this embodiment of the present invention.

Optionally, CG configuration information for the SDT, including but not limited to at least one of: CG resource configuration information, configuration information for CG-SDT selection criteria. For example: a packet threshold at CG-SDT selection, a measurement threshold, and a Timing Advance (TA) validity threshold or timer. In CG-SDT procedures, the TA for CG must be active, otherwise UL timing is not aligned and the base station cannot decode the upstream data. In order to ensure the validity of the TA, one of the prescribed methods is that the measurement result of the terminal cannot exceed the configured TA validity threshold value. If the measurement result of the terminal exceeds the threshold value, the terminal is considered to perform a larger range of movement, and TA is invalid. In order to ensure the validity of the TA, the second method is to configure a timing advance timer (Timing Advance Timer, TAT) on the terminal side, and the TA is always valid until the TAT expires.

Step 42: and the terminal performs a CG-SDT process based on configuration authorization according to the CG configuration information.

Optionally, the terminal may perform SDT selection according to SDT configuration information, and if CG-SDT conditions are satisfied according to the CG configuration information, a CG-SDT procedure may be performed.

Step 43: and the terminal sends the first information related to the CG-SDT to the network equipment, wherein the first information is used for optimizing the configuration information related to the CG-SDT.

Wherein the first information includes one or more of:

CG resource-related information for the CG-SDT process;

the related information of the reason for failure of the CG-SDT process;

Optionally, the terminal may record CG resource related information in an inactive state or an idle state, and mark successful triggering of SDT transmission or failed SDT transmission on the CG resource, so as to report the result to the network device, so as to optimize CG resource configuration. The reasons of failure may also be reported to the network device for the failed SDT transmission, so as to optimize CG-SDT related configuration information, such as CG resource configuration of the SDT, or parameter configuration of cell selection reselection, or parameter configuration related to radio link failure (Radio Link Failure, RLF), etc., which are not limited in the embodiments of the present invention.

Optionally, the terminal may successfully access the network through the RA of the non-SDT, in which case the terminal may report, during the RA reporting process, the information related to its CG-SDT transmission process before the RA of the non-SDT accesses the network, for optimizing the CG resource configuration related to SDT, etc.

In the above scheme, the terminal receives the SDT configuration information sent by the network device, performs a CG-SDT process according to CG configuration information for SDT in the SDT configuration information, and sends first information related to the CG-SDT to the network device, where the first information is used to optimize the CG-SDT related configuration information. Therefore, the network equipment side can be ensured to acquire the first information related to the CG-SDT, so that the network equipment can optimize the configuration information related to the CG-SDT according to the first information, thereby reducing resource waste and ensuring that the terminal can more effectively send and receive data through the SDT.

step 61: and the terminal receives the RA configuration information sent by the network equipment.

Step 62: and the terminal performs an RA process according to the RA configuration information.

Step 63: the terminal sends third information related to the shared RO of the RA to the network device, wherein the third information is used for optimizing configuration information related to the shared RO of the RA.

Optionally, the specific content of the third information may be referred to the above embodiment, and in order to avoid repetition, a description is omitted here.

The information transmission method of the present invention is described below with reference to examples:

example 1: the CG resource related information of the CG-SDT process comprises CG resource related information of the CG-SDT process which is successfully transmitted; as shown in fig. 7, the method specifically comprises the following steps:

step 1: the UE receives the SDT configuration information sent by the network side, the process comprises the steps that the UE acquires the configuration information of the CG for the SDT in a connection state or acquires the configuration information of the CG for the SDT in the SDT transmission process, and the UE acquires the RACH configuration for the SDT through system broadcast information.

The configuration information of the CG for the SDT herein includes the resource configuration information of the CG, as well as the configuration information of the selection criteria for the CG-SDT. For example: a packet threshold at CG-SDT selection, a measurement threshold, and a TA validity threshold or timer. In CG-SDT procedures, the TA for CG must be active, otherwise UL timing is not aligned and the base station cannot decode the upstream data. In order to ensure the validity of the TA, one of the specified methods is that the measurement result of the UE cannot exceed the configured TA validity threshold value, and if the measurement result of the UE exceeds the threshold value, the UE is considered to perform a larger range of movement, so that the TA is invalid. In order to ensure the validity of the TA, the second method is to configure a timing advance timer TAT at the UE side, and the TA is always valid until the TAT expires.

Step 2: the UE records the information of CG resources in an inactive state or an idle state, and marks that the CG resources successfully trigger the transmission of SDT. The CG resource information recorded includes, but is not limited to, at least one of:

Beam information corresponding to CG resources of a successful CG-SDT process is transmitted; for example: the beam information may include, but is not limited to, at least one of: beam identification information, beam configuration information, beam level measurements, and the like. Here, beam, or SSB, the corresponding SSB information on CG resources includes, but is not limited to, at least one of: SSB ID information, SSB configuration information, SSB level measurement results, and the like.

The terminal transmits the state information of successful CG-SDT process; for example: the state information may be in an Idle state (e.g., SDT/SON) for the terminal, or the state information may be in an inactive state for the terminal.

Step 3: and the UE reports the information to a network side, and the network side determines whether to adjust the configuration of CG resources corresponding to the UE or update TAT values or TA validity threshold values related to TAT validity according to CG resource related information of successfully executing the CG-SDT process reported by the UE. More specifically, the method comprises the following steps:

for example: and distributing more or less CG resources to the UE based on the size of a data packet of the UE successfully triggering the CG-SDT process and a channel quality result, and adjusting MCS parameters corresponding to the CG resources. If the channel quality of the UE is always good, fewer CG resources can be allocated, and MSC parameters are higher, so that the utilization rate of CG resources can be solved, and the CG using efficiency is improved.

Also for example: based on the fact that TAT is not expired when the UE successfully triggers the SDT-CG and the change of the measurement result does not exceed the threshold value of TA validity, a longer TAT is distributed to the UE, and the probability that the UE successfully uses the CG-SDT is increased.

Example 2: the CG resource related information of the CG-SDT process comprises CG resource related information of the CG-SDT process with initial transmission failure; as shown in fig. 8, the method specifically comprises the following steps:

Step 2: in the inactive state or the idle state, the UE records information of CG resources failing to trigger the CG-SDT procedure initially, where the recorded information includes, but is not limited to, at least one of the following:

indication information indicating that the CG-SDT timer is expired and no feedback is received by the initial transmission.

Step 3: and the UE reports the information to a network side, and the network side determines whether to adjust the configuration of CG resources corresponding to the UE or update TAT values or TA validity threshold values related to TAT validity according to CG resource related information of failure in the CG-SDT process reported by the UE. More specifically, the method comprises the following steps:

for example: and allocating more or less CG resources to the UE based on the size of the data packet of which the UE fails to trigger the CG-SDT process and a channel quality result, and adjusting MCS parameters corresponding to the CG resources. If the channel quality of the UE is always poor, more CG resources can be allocated, MSC parameters are lower, and thus the success rate of using CG-SDT by the UE is improved.

Also for example: based on the fact that TAT is out of date when the UE initially selects CG-SDT and the change of the measurement result exceeds the threshold value of TA effectiveness, a shorter TAT is distributed to the UE, and the probability of the UE successfully using CG-SDT is increased.

The CG resource related information of the CG-SDT process comprises CG resource related information of the CG-SDT process of subsequent transmission failure; as shown in fig. 9, the method specifically comprises the following steps:

Step 2: in the inactive state or the idle state, the UE records information of CG resources failing to trigger the CG-SDT process in subsequent transmission, where the recorded information includes, but is not limited to, at least one of the following:

and the indication information is used for indicating that the CG-SDT timer expires and no feedback is received in subsequent transmission.

for example: and allocating more or less CG resources to the UE according to the size of the data packet and the channel quality result of the UE failed to trigger the CG-SDT process, and adjusting MCS parameters corresponding to the CG resources. If the channel quality of the UE is always poor, more CG resources can be allocated, MSC parameters are lower, and thus the success rate of using CG-SDT by the UE is improved.

Also for example: based on the fact that TAT is out of date when the UE initially selects the SDT-CG and the change of the measurement result exceeds the threshold value of TA effectiveness, a shorter TAT is distributed to the UE, and the probability of the UE successfully using the SDT-CG is increased. For the case where the CG-SDT timer expires and no feedback is received for subsequent transmissions (non-initial transmissions), the network side may need to further optimize parameters related to packet transmissions between CUs-DUs.

In embodiment 4, the CG-SDT related information includes information related to a cause of failure of the CG-SDT process, the RA-SDT related information includes information related to a cause of failure of the RA-SDT process, that is, the SDT related information includes information related to a cause of failure of the SDT process.

Specifically, the SDT procedure of the UE may send the data packet using CG-SDT, and may send the data packet using RA-SDT. In either SDT mode, there may be cases where SDT fails, i.e., the SDT process may be unsuccessful, including the following reasons:

(1) Cell reselection;

(2) The SDT timer expires;

(3) RLC reaches maximum retransmission times;

if the situation occurs, the UE may change from the inactive state to the ilde state, and consider that the SDT fails, the terminal may report such information to the base station, which is used for the base station to optimize CG resources of the SDT, or RA resources of the SDT, or is used for optimizing configuration of cell selection reselection parameters, configuration of RLF related parameters, and so on.

Such information includes, but is not limited to, at least one of:

Based on the above information, the network side may further optimize related parameters, for example, if the reason for the occurrence of the state transition is that the RLC layer reaches the maximum retransmission times, and reports the channel quality information of the source cell, which indicates that the channel quality of the network is poor, the network side may increase the threshold value of SDT transmission, so that the UE cannot trigger to adopt SDT transmission based on such channel measurement, that is, the network increases the channel threshold requirement of SDT transmission.

Embodiment 5 CG-SDT related information includes CG-SDT related information prior to an RA access network other than SDT, RA-SDT related information includes RA-SDT related information prior to an RA access network other than SDT, i.e., SDT related information includes SDT related information prior to an RA access network other than SDT.

Specifically, for RA-SDT, the network needs to configure SDT-specific 2-step RACH resources, as well as SDT-specific 4-step RACH resources. Both types of resources are contention based RACH resources. If the RA resource for SDT is not optimized, the UE may not always meet the condition of RA-SDT access, and the RA resource for SDT configured by the network side may be wasted, and the UE may not enjoy the benefits of low power consumption and short delay of RA-SDT flow.

And the terminal can successfully access the network through the existing non-SDT RA, and the terminal can report whether the terminal experiences SDT transmission before the non-SDT RA access network in the RA reporting process, so as to optimize the RA resource configuration or CG resource configuration related to the SDT.

The reported information includes, but is not limited to, at least one of the following:

indication information for indicating whether an SDT transmission procedure is to be performed before an RA access network other than SDT, e.g., the indication information may be used to indicate whether RA-SDT and/or CG-SDT is to be performed before an RA access network other than SDT;

Indication information for indicating that the terminal fails to trigger the RA procedure of the non-SDT when the CG-SDT procedure is experienced; if the terminal can also indicate that the terminal experiences initial transmission failure or subsequent transmission failure;

Indication information for indicating that the terminal fails to trigger the RA procedure of the non-SDT through the RA-SDT procedure of the first type; if the terminal can also indicate that the terminal experiences initial transmission failure or subsequent transmission failure;

indication information for indicating that the terminal failed to trigger the RA procedure other than SDT through the RA-SDT procedure of the second type; if the terminal can also indicate that the terminal experiences initial transmission failure or subsequent transmission failure;

Based on the above information, the network side may have a preliminary judgment on the SDT data transmission process of the UE before RA random access, and may be used for the network side to decide whether to let the UE continue reporting the SDT-related network preference parameters.

Alternatively, the above information may be reported to the network side through RA reports.

Example 6: optimizing RA resources;

specifically, the UE may initiate a random access procedure from the 2-step RA because the backoff mechanism or the maximum number of transmissions of the 2-step RA is reached, and the UE rolls back to the 4-step RA. The UE may report the uplink resource information where the RA is located in order to optimize the uplink resource configuration of the RA. For the procedure that the 2-step RA returns to the 4-step RA here, if the network side configures the shared RO, the RA resource information of the 2-step RA and the RA resource information of the 4-step RA, which are possibly reported by the UE, are the same, so that only the resource configuration information of the 2-step RA or the 4-step RA can be reported, and the network side can explicitly know that the UE is successfully accessed by using the 4-step RA under the shared RO configuration. However, the network side only knows that the terminal works in the RO sharing mode, but may not record specific parameters when the RO is shared, so that the parameters corresponding to the RO sharing cannot be further optimized.

Optionally, the UE may report the shared RO related parameter to the network in the RA report, which may include msgA-CB-preambibeperssb-persshared RO and msgA-SSB-SharedRO-MaskIndex related information, for displaying a random access channel resource indicating that the 2-step RA of the UE shares the 4-step RA, so that the network further optimizes the proportionality parameter of the shared resource.

Specifically, msgA-CB-preambisoperssb-PerSharedRO indicates the number of contention-based random access preambles of 2-step RA mapped to each SSB when PRACH occasions are shared between 2-step RA and 4-step RA (defines the number of contention-based Random Access Preambles for 2-step RA type mapped to each SSB when the PRACH occasions are shared between 2-step and 4-step RA types)

msgA-SSB-SharedRO-MaskIndex represents a subset of 2-step RA and 4-step RA type shared ROs per SSB. If 2-step RA shares RO with 4-step RA and msgA SSB SharedRO MaskIndex is not configured, then RO of all 4-step RA can be used for 2-step RA (Indicates the subset of 4-step RA type PRACH occasions shared with 2-step RA type PRACH occasions for each SSB.if 2-step RA type PRACH occasions are shared with 4-step RA type PRACH occasions and msgA-SSB-SharedRO-MaskIndex is not configured, then all 4-step RA type PRACH occasions are available for 2-step RA type).

Optionally, when the RA-SDT may also be reported in the RA report, the 2-step RA-SDT and the 4-step RA-SDT share information about RA resources, where the reporting content includes, but is not limited to, at least one of the following:

the network side configures the msgA-CB-preambisoperssb-PerSharedRO parameters for SDT, i.e., the number of contention-based random access preambles for 2step RA on each SSB when the 2-step RA-SDT and 4-step RA-SDT share PRACH occlusions.

The msgA-SSB-SharedRO-MaskIndex parameter for SDT configured at the network side, i.e. for each SSB,2-step RA-SDT shares subset information of PRACH occisions in RA resources of 4-step RA-SDT.

Indication information for indicating whether the 2-step RA-SDT uses shared RO resources of the 4-step RA-SDT, the RO resources including time-frequency resources and/or wraparound code resources. The indication information may implicitly indicate that the 2-step RA-SDT shares RO resources of the 4-step RA-SDT by reporting PUSCH resource information of the 4-step RA.

Alternatively, the terminal may report the above information to the network side through RA report.

In the above scheme, the network side can optimize CG or RA configuration of SDT through recorded CG-SDT process reported by UE or related information of SDT process before normal RA access, so that UE can send and receive data more effectively using SDT. In addition, the network side can optimize the relevant configuration of the shared RO through the information of the shared RO reported by the UE, so that the UE can more effectively use the shared RO to initiate a random access process.
