Description

Transmission method of random access information, terminal and network side equipment

Technical Field

The present invention relates to the field of communications technologies, and in particular, to a method, a terminal, and a network device for transmitting random access information.

Background

Currently, there are two-step Random Access Channel (2-step RACH) technology and 4-step Random Access (4-step RACH) technology in communication technology. Compared with the four-step random access technology, the two-step random access technology has the main technical characteristics that the average time consumption of the random access process is reduced, and the application prospect of the two-step random access technology is very clear for time delay sensitive and large time delay scenes.

Furthermore, a random access procedure may involve multiple random access attempts, and the distribution of the multiple random access attempt types includes various cases, such as:

scene 1A: all random access attempt types contained in one random access process are 2-step RACH, and each two-step random access attempt has no fallback (namely, the two-step random access attempt is regressed to the four-step random access attempt);

scene 1B: all random access attempt types contained in one random access process are 2-step RACH, and a fallback situation occurs in at least one two-step random access attempt;

scene 2: all random access attempt types contained in one random access process are 4-step RACH;

scene 3A: the type of the former part of random access attempts in all random access attempts contained in one random access process is 2-step RACH, the fallback situation does not exist in each two-step random access attempt, the remaining random access attempts are 4-step RACH, and the frequency resource information used by the 2-step RACH and the 4-step RACH is the same;

scene 3B: the type of the former part of random access attempts in all random access attempts contained in one random access process is 2-step RACH, the fallback situation does not exist in each two-step random access attempt, the remaining random access attempts are 4-step RACH, and the frequency resource information used by the 2-step RACH and the 4-step RACH is different;

scene 3C: the type of the former part of random access attempts in all random access attempts contained in one random access process is 2-step RACH, and there is a fallback situation that at least one two-step random access attempt occurs, the remaining random access attempt types are 4-step RACH, and the frequency resource information used by the 2-step RACH and the 4-step RACH is the same;

scene 3D: the former part of random access attempt types in all random access attempts contained in one random access process are 2-step RACH, and there is a fallback situation of at least one two-step random access attempt, the remaining random access attempt types are 4-step RACH, and the frequency resource information used by the 2-step RACH and the 4-step RACH is different.

For the above scenario, the random access record information reported by the terminal cannot distinguish the type of each random access attempt.

The term "and/or" in the embodiments of the present invention describes an association relationship of associated objects, and indicates that three relationships may exist, for example, a and/or B may indicate: a exists alone, A and B exist simultaneously, and B exists alone. The character "three types" generally indicates that the former and latter associated objects are in an "or" relationship.

The term "plurality" in the embodiments of the present invention means two or more, and other terms are similar thereto.

Furthermore, it should be appreciated that reference throughout this specification to "one embodiment" or "an embodiment" means that a particular feature, structure or characteristic described in connection with the embodiment is included in at least one embodiment of the present invention. Thus, the appearances of the phrases "in one embodiment" or "in an embodiment" in various places throughout this specification are not necessarily all referring to the same embodiment. Furthermore, the particular features, structures, or characteristics may be combined in any suitable manner in one or more embodiments.

In various embodiments of the present invention, it should be understood that the sequence numbers of the following processes do not mean the execution sequence, and the execution sequence of each process should be determined by its function and inherent logic, and should not constitute any limitation to the implementation process of the embodiments of the present invention.

Specifically, 2-step and 4-step RACH are described herein.

In a 2-step random access non-Fallback (no Fallback to four-step random access attempt) scenario, firstly, a terminal selects a 2-step RACH as a type of the current RACH attempt and sends an MSG a to a network side, then the terminal receives an MSG B message which is sent by the network side and does not contain Fallback to four-step random access indication information in an MSG B receiving window, at this time, once the terminal receives the MSG B successfully, the terminal indicates that the current 2-step RACH attempt is successful, and if the terminal cannot successfully receive the MSG B until the MSG B receiving window is over, the terminal indicates that the current 2-step RACH attempt fails.

In a 2-step random access Fallback scenario, a terminal selects a 2-step RACH as a current RACH attempt type and sends MSG A to a network side, then the terminal receives an MSG B message which is sent by the network side and contains indication information of Fallback to four-step random access in an MSG B receiving window, then the terminal sends MSG 3 on resources indicated by the MSG B, and finally the terminal receives MSG 4 sent by the network side in a contention resolution window, at the moment, once the terminal receives the MSG 4 successfully, the 2-step RACH attempt is successful, and if the terminal cannot receive the MSG 4 successfully until the MSG 4 receiving window is over, the 2-step RACH attempt is failed.

In a 4-step random access scene, firstly, a terminal selects a 4-step RACH as a current RACH attempt type and sends MSG 1 to a network side, then the terminal receives MSG2 information sent by the network side in an MSG2 receiving window, then the terminal sends MSG 3 on a resource indicated by the MSG2, and finally the terminal receives MSG 4 sent by the network side in a competition resolving window, at the moment, once the terminal receives the MSG 4 successfully, the 4-step RACH attempt at the current time is successful, and if the terminal cannot receive the MSG 4 successfully until the MSG 4 receiving window is over, the 4-step RACH attempt at the current time is failed.

The random access record information reported by the existing terminal exists in a random access Report (RACH Report) or a Radio Link Failure (RLF) Report, and may specifically include the following information: the random access method includes using RACH frequency resource related information used in the current random access process, cause value information initiated in the current random access process, Synchronization Signal Block (SSB)/Channel state information-reference Signal (Channel state information-RS) index involved in the current random access process, and random access attempt number information sent in the SSB/CSI-RS index, indication information of whether cell Signal quality is higher than an SSB threshold in each random access attempt process in the current random access process, and indication information of whether a contention random access process is detected in the current random access attempt process. In addition, if the random access procedure initiated cause value information is different, the terminal may record multiple sets of random access procedure record information, and each set of recorded information includes the above 4 types of information. However, the random access record information reported by the terminal cannot reflect the unique technical characteristics of the 2-step RACH and the possible fallback interaction information of the 2-step RACH and the 4-step RACH, and even if the network side acquires the recorded random access record information from the terminal side, the network side cannot perform relatively independent optimization for specific random access types, that is, it is unknown which data is used to optimize the 2-step RACH and which data is used to optimize the 4-step RACH.

For this purpose, the present invention provides the following embodiments to realize that the network side can clearly identify that each time the random access attempt type initiated by the terminal is 2-step RACH related or 4-step RACH related or both 2-step RACH and 4-step RACH related (i.e. fallback scenario).

As shown in fig. 1, a flowchart of steps of a method for transmitting random access information applied to a terminal in an embodiment of the present invention is shown, where the method includes the following steps:

step 101: and reporting the characteristic related information of the random access type used by the random access attempt in the random access process of the terminal to the network side equipment.

Specifically, in the random access process, the terminal reports the characteristic related information of the random access type used in the random access attempt in the random access process to the network side device.

The characteristic related information is used for indicating the random access type characteristic associated with each random access attempt of the terminal in the current random access process, so that the network side equipment determines the random access type characteristic associated with each random access attempt of the terminal in the current random access process according to the characteristic related information of the random access type reported by the terminal.

Specifically, the random access type may be two-step random access, four-step random access, or two-step random access fallback to four-step random access.

Therefore, the terminal reports the feature related information of the random access type used by the random access attempt in the random access process of the terminal to the network side equipment, so that the network side equipment can determine the random access type feature associated with each random access attempt of the terminal in the random access process, and the network side equipment can clearly identify whether the random access type used by each random access attempt of the terminal in the random access process is two-step random access, four-step random access or two-step random access fallback to four-step random access, so that the network side equipment can perform optimization operation aiming at different types of random access configuration resources, and further different types of random access configuration can be better suitable for application scenes associated with different random access types.

Further, the feature related information of the random access type includes at least one of the following information:

(1) and in the random access process of the terminal, the network side only configures the indication information of two steps of random access resources.

Specifically, the terminal reports whether the network side is configured with two-step random access resources in the current random access process of the terminal, so that the network side equipment can clearly know whether the terminal can only use two-step random access types to try to access in the current random access process, and further can perform random access optimization by referring to the information and the random access condition.

(2) And indicating information whether the network side starts a conversion function from two-step random access to four-step random access in the random access process of the terminal.

Specifically, the terminal reports whether the network side starts a conversion function from two-step random access to four-step random access in the current random access process of the terminal, so that the network side equipment can know whether the terminal can adopt a backspacing function to try to access, and the network side equipment can refer to the information to perform random access optimization.

It should be noted that, by reporting the above (1) and (2), the terminal enables the network side device to clearly know the reason why the terminal completes the random access procedure using the two-step random access type, where the reason may be that the four-step random access resource is not configured, or that the four-step random access resource is configured but the switching function from the two-step random access to the four-step random access is not started, or that the four-step random access resource is configured and the switching function from the two-step random access to the four-step random access is started, but the two-step random access type is selected to complete the random access procedure due to the initial cell signal quality. After knowing the reasons, the network side device can optimize the resource allocation of random access through the reasons, for example, add four-step random access resource allocation and/or a conversion function from two-step random access to four-step random access, instead of optimizing only the resource allocation corresponding to two-step random access, thereby realizing efficient optimization of random and then configured resources.

(3) And the random access frequency resource information used in the random access process of the terminal.

Specifically, the terminal reports the frequency resource information of the random access used in the random access process, so that the network side equipment can clearly know the frequency resource information used by the two-step random access and/or the four-step random access attempt, and the network side equipment can determine and optimize the frequency resource information to be optimized.

(4) A threshold value of the maximum number of transmissions of the random access message msgA before the transition from the two-step random access attempt type to the four-step random access attempt type is recorded when a preset recording condition is satisfied.

Specifically, when the terminal determines that the preset recording condition is met, the terminal may report the recorded maximum transmission frequency threshold of the random access message msgA before the two-step random access attempt type is converted into the four-step random access attempt type to the network side device, so that the network side device can know the maximum attempt frequency of the two-step random access attempt before the conversion into the four-step random access attempt in the current random access process, and further the network side device can optimize the maximum transmission frequency threshold according to the record and the access condition.

Specifically, the preset recording condition may include:

the network side equipment is configured with a maximum transmission time threshold value of msgA before switching from two-step random access attempt to four-step random access attempt; and the number of the first and second groups,

the network side equipment is configured with resources related to the two-step random access type and the four-step random access type; and the number of the first and second groups,

in the random access process of the terminal, a transmission frequency counter of a random access lead code recorded by the terminal is the sum of the maximum transmission frequency threshold value of msgA and 1, and a random access message sent in the last random access attempt in the past is msgA; or, the transmission number counter of the random access preamble recorded by the terminal is the sum of the maximum transmission number threshold value of msgA and 1, and the random access message sent when the last random access attempt failed and the random access attempt failed in the past is msgA.

That is, when the terminal detects that the synchronization satisfies the above condition, it may record the maximum transmission number threshold of the random access message msgA before the two-step random access attempt type is switched to the four-step random access attempt type, thereby ensuring the validity of the recording.

(5) In the random access process of the terminal, the number of times of random access attempts by using a two-step random access type or the number of times of random access attempts by using a four-step random access type or the number of times of transmission of a random access message msgA in all random access attempts transmitted by the terminal.

Specifically, the terminal reports the information, so that the network side device can clearly know how many times the terminal uses the two-step random access attempt or the four-step random access attempt respectively in the random access process, and further the network side device can use the corresponding random access attempt to record and optimize the random access resource of the corresponding type.

(6) In the random access process of the terminal, whether indication information for returning from the two-step random access attempt to the four-step random access attempt exists every time the random access attempt is performed by using the two-step random access type.

Specifically, in the current random access process of the terminal, 1 bit may be used for each two-step random access attempt to indicate whether the current two-step random access attempt involves a fallback from the two-step random access attempt to a four-step random access attempt (fallback function).

In addition, the terminal reports whether the backoff exists or not when the random access attempt is performed by using the two-step random access type each time, so that the network side equipment can clearly know whether the backoff exists or not in each two-step random access attempt, and further the network side equipment can refer to the information to perform random access optimization.

(7) And in the random access process of the terminal, performing random access attempt by using two random access types each time, and obtaining the cell signal quality when backspacing occurs.

Specifically, the terminal reports the cell signal quality when the terminal performs the random access attempt by using the two-step random access type each time and generates backoff, so that the network side equipment can clearly know whether the cause of the backoff generated by using the two-step random access attempt each time is related to the cell signal quality, the network side equipment can know the detail point of the random access attempt at each time, and the network side equipment can perform random access optimization with reference to the information.

(8) And in the random access process of the terminal, when the random access attempt is performed by using the two-step random access type every time, indicating information indicating whether the signal quality of the associated Synchronization Signal Block (SSB) is higher than a preset quality threshold value or not.

Specifically, the terminal reports whether the signal quality of the associated SSB is higher than a preset quality threshold value each time the random access attempt is performed using the two-step random access type, so that the network side device can clearly know the signal quality of the associated SSB each time the two-step random access attempt is performed, and thus the network side device can know the detail point of each two-step random access attempt, and the network side device can perform random access optimization with reference to the information.

It should be noted that, through the information in (6), (7), and (8), the network side device can clearly know the minutiae of each two-step random access attempt, and can further refer to the information to optimize when to start the fallback function, so as to improve the success rate of this random access.

(9) In the random access process of the terminal, the random access attempt is carried out by using the four-step random access type every time, and the attempt fails to be the first failure reason.

Specifically, in the current random access process of the terminal, 1 bit may be used for indicating which reason the current random access attempt fails to be the first failure reason each time the four-step random access attempt is performed.

Wherein, the first failure reason may include: when the random access response window is overtime, the terminal does not receive msg2 containing a random access code corner mark used by the terminal for the random access attempt; alternatively, the random access contention fails.

Specifically, the reason why the contention resolution is not successful may be that a random access contention resolution timer (ra-ContentionResolutionTimer) is overtime, or that although the terminal demodulates a PDCCH scrambled by a temporary cell radio network temporary identifier (C-RNTI) and a MAC layer protocol data unit (MAC PDU for short), a contention resolution identifier included in the MAC PDU is not matched with an identifier sent by the terminal MSG 3.

The terminal reports the first failure reason when the random access attempt is performed by using the four-step random access type every time and the attempt fails, so that the network side equipment can clearly know the reason of the random access attempt and the attempt failure every time, and further the network side equipment can perform random access optimization by referring to the information.

(10) And in the random access process of the terminal, performing random access attempt by using a two-step random access type every time, and obtaining a second failure reason when the attempt fails.

Specifically, in the current random access process of the terminal, 1 bit may be used for indicating which reason the second failure reason of the current random access attempt and the attempt failed in each of two random access attempts.

Wherein, the second failure reason may include: when the random access response window is overtime, the terminal does not receive the msgB containing the random access code corner mark used by the random access attempt of the terminal or the msgB of the PDCCH scrambled by the C-RNTI of the terminal; alternatively, the random access contention fails.

Specifically, the reason why the random access contention fails, that is, contention resolution is not successful, may be that a random access contention resolution timer is overtime, or that although the terminal demodulates the PDCCH and the MAC PDU scrambled by the temporary C-RNTI, a contention resolution identifier included in the MAC PDU does not match an identifier sent by the terminal MSG 3.

The terminal reports the second failure reason when the random access attempt is performed by using the two-step random access type every time and the attempt fails, so that the network side equipment can clearly know the reason of the random access attempt and the attempt failure every time, and further the network side equipment can refer to the information to perform random access optimization.

(11) In the random access process of the terminal, the third failure reason when each random access attempt can not completely receive the random access response message msg2 or msgB,

specifically, the third failure reason is that demodulation of a physical downlink control channel (PDCCH for short) is unsuccessful or demodulation of a physical downlink shared channel (PDSCH for short) is unsuccessful.

Specifically, the terminal reports the third failure reason when the random access attempt cannot completely receive the message msg2 or msgB each time, so that the network side device can clearly know the reason why the msg2 or msgB cannot completely receive, and further the network side device can perform random access optimization with reference to the information.

It should be noted that, the network side device can clearly know details of failure of each random access attempt through the information in (9), (10), and (11), and can further optimize the random access by using different strategies with reference to the information, so as to improve the success rate of the random access.

In this way, the terminal reports at least one of the above information as the characteristic related information of the random access type, so that the network side device can clearly know the characteristic related information of the random access type used in each random access attempt, such as frequency resource information, the random access type used in each attempt, the reason for failure in each attempt, the reason for backspacing of two random access attempts at each time, the number of times of access attempts of each random access type, and the like, so that the network side device can know the random access type used in each random access attempt based on the information, and can optimize different types of random access configuration resources by using different strategies with reference to the information.

In addition, further, the terminal reports, to the network side device, the feature related information of the random access type used by the terminal when attempting random access in the current random access process, where the feature related information includes any one of the following items:

firstly, sending connection establishment failure record information or connection recovery failure record information to network side equipment, wherein both the connection establishment failure record information and the connection recovery failure record information comprise feature related information of a random access type;

secondly, sending radio link failure record information or switching failure record information to network side equipment, wherein the radio link failure record information and the switching failure record information both contain characteristic related information of a random access type;

thirdly, sending random access success record information to the network side equipment, wherein the random access success record information comprises characteristic related information of random access types;

fourthly, sending Main Cell Group (MCG) failure record information or auxiliary cell group (SCG) failure record information to the network side equipment, wherein the MCG failure record information and the SCG failure record information both comprise feature related information of a random access type;

and fifthly, sending failure record information to the network side equipment, wherein the failure record information contains characteristic related information of the random access type.

That is, the terminal can include the feature related information of the random access type in any one of the record information and send the record information to the network side for failure, thereby realizing the report of the feature information of the random access type and realizing the diversification of the report ways of the feature related information of the random access type.

Before reporting the feature related information of the random access type used by the random access attempt in the current random access process of the terminal to the network side equipment, the terminal also needs to send a first indication message to the network side equipment, wherein the first indication message is used for indicating that the network side equipment can obtain the feature related information of the random access type; and then receiving a second indication message sent by the network side equipment based on the first indication message, wherein the second indication message is used for indicating the terminal to report the characteristic related information of the random access type. At this time, when the terminal reports the feature related information of the random access type used by the random access attempt in the current random access process of the terminal to the network side device, the terminal may report the record including the feature related information of the random access type to the network side device based on the second indication message.

That is, before reporting the feature related information of the random access type, the terminal needs to inform the network side device that the record of the feature related information of the random access type is available, and then when the network side device indicates the terminal to report the feature related information of the random access type, the terminal reports the feature related information of the random access type to the terminal, thereby avoiding the situation that the terminal reports the feature related information of the random access type when the network side device does not need the feature related information of the random access type, which causes the waste of transmission resources.

It should be noted that, when the terminal sends the first indication message to the network side device, any one of the following sending methods may be included:

firstly, a Radio Resource Control (RRC) reestablishment completion message is sent to network side equipment, wherein the RRC reestablishment completion message comprises a first indication message;

secondly, sending an RRC reconfiguration complete message to the network side equipment, wherein the RRC reconfiguration complete message comprises a first indication message;

thirdly, sending an RRC connection recovery completion message to the network side equipment, wherein the RRC connection recovery completion message comprises a first indication message;

fourthly, sending an RRC connection establishment completion message to the network side equipment, wherein the RRC connection establishment completion message comprises a first indication message;

and fifthly, sending a terminal information response message to the network side equipment, wherein the terminal information response message contains the first indication message.

That is, the terminal can transmit the first indication message through any one of the messages, and the diversity of the first indication message transmission modes is realized.

In this way, the terminal in this embodiment reports, to the network side device, the feature related information of the random access type used by the terminal in the random access attempt in the current random access process, so that the network side device can clearly identify the random access type feature associated with each random access attempt of the terminal in the current random access process, and thus the network side device can perform optimization operation on different types of random access configuration resources, and further, different types of random access configurations can be better suitable for application scenarios associated with different random access types.

In addition, as shown in fig. 2, a flowchart of a step of a method for transmitting random access information applied to a network side device in the embodiment of the present invention is shown, where the method includes the following steps:

step 201: and receiving the characteristic related information of the random access type used by the random access attempt in the random access process of the terminal reported by the terminal.

Specifically, in the current random access process, the terminal reports the characteristic related information of the random access type used in the random access attempt in the current random access process to the network side device, and at this time, the network side device receives the characteristic related information of the random access type used in the random access attempt in the current random access process reported by the terminal.

The characteristic related information is used for indicating the random access type characteristic associated with each random access attempt of the terminal in the current random access process.
