[0002] In NR-U (New Radio Unlicensed) systems, whether a terminal device can successfully send a preamble for random access depends on whether the terminal device can successfully perform LBT (listen-before-talk).

[0041] To better understand the information reporting method and apparatus disclosed in this disclosure, the communication system to which this disclosure applies will be described first.
[0042] Please see Figure 1 , Figure 1This is a schematic diagram of the architecture of a communication system provided in an embodiment of the present disclosure. The communication system may include, but is not limited to, a network-side device and a terminal device. Figure 1 The number and form of devices shown are for illustrative purposes only and do not constitute a limitation on the embodiments of this disclosure. In actual applications, there may be two or more network-side devices and two or more terminal devices. Figure 1 The communication system 10 shown is exemplified by including a network-side device 101 and a terminal device 102.
[0043] It should be noted that the technical solutions of this disclosure can be applied to various communication systems. For example, Long Term Evolution (LTE) systems, 5th Generation (5G) mobile communication systems, 5G New Radio (NR) systems, or other future new mobile communication systems.
[0044] The network-side device 101 in this embodiment is a network-side entity used for transmitting or receiving signals. For example, the network-side device 101 can be an evolved NodeB (eNB), a transmission reception point (TRP), a next-generation NodeB (gNB) in an NR system, a base station in other future mobile communication systems, or an access node in a wireless fidelity (WiFi) system. This disclosure does not limit the specific technology or equipment form used in the base station. The base station provided in this disclosure can be composed of a central unit (CU) and a distributed unit (DU). The CU can also be called a control unit. Using a CU-DU structure, the base station, for example, can have its protocol layer separated. Some protocol layer functions are centrally controlled by the CU, while the remaining or all protocol layer functions are distributed in the DU, which is centrally controlled by the CU.
[0045] The terminal device 102 in this disclosure is a user-side entity used to receive or transmit signals, such as a mobile phone. The terminal device can also be referred to as a terminal, user equipment (UE), mobile station (MS), mobile terminal (MT), etc. The terminal device can be a car with communication capabilities, a smart car, a mobile phone, a wearable device, a tablet computer, a computer with wireless transceiver capabilities, a virtual reality (VR) terminal device, an augmented reality (AR) terminal device, a wireless terminal device in industrial control, a wireless terminal device in self-driving, a wireless terminal device in remote medical surgery, a wireless terminal device in a smart grid, a wireless terminal device in transportation safety, a wireless terminal device in a smart city, a wireless terminal device in a smart home, etc. This disclosure does not limit the specific technology or device form used in the terminal device.
[0046] It is understood that the communication system described in the embodiments of this disclosure is for the purpose of more clearly illustrating the technical solutions of the embodiments of this disclosure, and does not constitute a limitation on the technical solutions provided in the embodiments of this disclosure. As those skilled in the art will know, with the evolution of system architecture and the emergence of new business scenarios, the technical solutions provided in the embodiments of this disclosure are also applicable to similar technical problems.
[0047] In addition, the following points are provided to facilitate understanding of the embodiments disclosed herein.
[0048] First, in this embodiment of the disclosure, "for indicating" can include both direct and indirect indication. When describing information as indicating A, it can include whether the information directly indicates A or indirectly indicates A, but does not necessarily mean that the information carries A.
[0049] The information indicated by the information is called the information to be indicated. In the specific implementation process, there are many ways to indicate the information to be indicated, such as, but not limited to, directly indicating the information to be indicated, such as the information to be indicated itself or its index. It can also be indirectly indicated by indicating other information, where there is a relationship between the other information and the information to be indicated. It can also indicate only a part of the information to be indicated, while the other parts are known or pre-agreed upon. For example, the indication of specific information can be achieved by using a pre-agreed (e.g., protocol-defined) arrangement of various pieces of information, thereby reducing the indication overhead to some extent.
[0050] The information to be instructed can be sent as a whole or divided into multiple sub-information messages, and the sending period and / or timing of these sub-information messages can be the same or different. This disclosure does not limit the specific sending method. The sending period and / or timing of these sub-information messages can be predefined, for example, according to a protocol.
[0051] Second, this disclosure provides multiple implementation methods to clearly illustrate the technical solutions of this disclosure. Of course, those skilled in the art will understand that the multiple embodiments provided in this disclosure can be executed individually, or in combination with the methods of other embodiments in this disclosure, or individually or in combination with some methods in other related technologies; this disclosure does not limit these aspects.
[0052] In this embodiment of the disclosure, when a connection establishment fails or a connection recovery fails, the terminal device stores a connection establishment failure report. Upon the next access to the network-side device, it notifies the network-side device of the availability of a available connection establishment failure report via a connection establishment complete / connection recovery complete / connection reconstruction complete / connection reconfiguration complete message. The network-side device can request a connection establishment failure report via a terminal device information request message, and the terminal device carries the connection establishment failure report via a terminal device information response message. Version 17 (R-17) introduces support for the terminal device to record multiple connection establishment failure reports. The content of the connection establishment failure report is as follows:
[0053]
[0054] The perRAInfoList-r16 field is mandatory for each random access information list. The format of perRAInfoList-r16 is as follows:
[0055]
[0056] The `numberOfPreamblesSentOnSSB-r16` field, which records the number of preambles sent on the SSB in each random access synchronization signal block information (PerRASSBInfo-r16), is mandatory and has a value range of (1, 200). For each SSB, if the terminal device uses its associated random access resource to send a preamble, there will be a corresponding `PerRASSBInfo-r16` record for that SSB. `numberOfPreamblesSentOnSSB-r16` records the number of consecutive preambles sent on that SSB. Its minimum value is 1 because, in non-NR-U scenarios, the terminal device will definitely send a preamble at least once on the random access resource associated with that SSB. However, for NR-U, whether the terminal device can send a preamble also depends on whether the terminal device can successfully perform a Level Bypass (LBT). If the LBT corresponding to the terminal device's preamble transmission fails, the terminal device cannot send a preamble. If all of the terminal device's preamble transmissions fail with their LBTs, then the preamble transmission count is 0. However, the terminal device still reports the number of preamble transmissions even when no preamble is successfully transmitted, but it does not support reporting 0.
[0057] Similarly, after a radio link failure (RLF) occurs, the terminal device will also record an RLF report, reporting it in a manner similar to a connection establishment failure report. If the RLF is caused by a handover failure, the terminal device's RLF report will include the random access common information (ra-InformationCommon), which must also carry perRAInfoList-r16. Additionally, the random access report (RA report) and successful handover reports will also include ra-InformationCommon. Secondary cell group (SCG) failure information will carry perRAInfoList-r16. Therefore, the same issues will arise.
[0058] Based on this, this disclosure provides an information reporting method. When a terminal device sends a random access preamble using random access resources associated with a reference signal, it reports to the network-side device the first number of times the random access preamble has been continuously sent on the reference signal. Thus, when a terminal device sends a random access preamble using random access resources associated with a reference signal, it can support reporting to the network-side device the first number of times the random access preamble has been continuously sent on the reference signal.
[0059] The information reporting method and apparatus provided in this disclosure will now be described in detail with reference to the accompanying drawings.
[0060] Please see Figure 2 , Figure 2 This is a flowchart of an information reporting method provided in an embodiment of this disclosure. For example... Figure 2 As shown, the method may include, but is not limited to, the following steps:
[0061] S21: In response to sending a random access preamble using a random access resource associated with a reference signal, the terminal device reports to the network-side device the first number of times the random access preamble has been sent consecutively on the reference signal, wherein the reference signal is an SSB or a CSI-RS.
[0062] In this embodiment of the present disclosure, when the terminal device sends a random access preamble using the random access resources associated with the reference signal, it reports to the network-side device the first number of times the random access preamble has been sent continuously on the reference signal.
[0063] The scenario where the terminal device uses the random access resources associated with the reference signal to send the preamble for random access can include scenario one: the terminal device uses the random access resources associated with the reference signal to send the preamble for random access and successfully performs LBT, thus successfully sending the preamble for random access; or it can also include scenario two: the terminal device uses the random access resources associated with the reference signal to send the preamble for random access and fails to perform LBT, thus failing to successfully send the preamble for random access, and so on.
[0064] In this embodiment of the disclosure, the terminal device uses random access resources associated with a reference signal to send a preamble for random access. The reference signal can be an SSB or a CSI-RS.
[0065] In one possible implementation, when the terminal device transmits a random access preamble using the random access resources associated with the SSB, it reports to the network-side device the first number of consecutive transmissions of the random access preamble on the reference signal.
[0066] For example, when the reference signal is SSB, if the terminal device sends a random access preamble using the random access resource associated with SSB#1, it reports to the network-side device the first number of times the random access preamble has been sent consecutively on SSB#1.
[0067] In one possible implementation, when the terminal device transmits a random access preamble using the random access resources associated with CSI-RS, it reports to the network-side device the first number of consecutive transmissions of the random access preamble on the reference signal.
[0068] For example, when the reference signal is CSI-RS, if the terminal device sends a random access preamble using the random access resources associated with CSI-RS#1, it reports to the network-side device the first number of times the random access preamble has been sent consecutively on CSI-RS#1.
[0069] In this embodiment of the present disclosure, when the terminal device sends a preamble of random access using the random access resources associated with the reference signal, it can store in advance the first number of consecutive transmissions of the preamble of random access on the reference signal, and when the network-side device requests a report, it can report the first number of consecutive transmissions of the preamble of random access on the reference signal to the network-side device.
[0070] It should be noted that when the terminal device transmits a random access preamble using the random access resources associated with the reference signal, it reports to the network-side device the first number of consecutive transmissions of the random access preamble on the reference signal. The first number can be the sum of the number of successful transmissions of the random access preamble on the reference signal and the second number of consecutive transmissions of the random access preamble on the reference signal that failed due to LBT failure; or, the first number can also be the number of successful transmissions of the random access preamble on the reference signal.
[0071] In some possible implementations, the case where the terminal device sends a random access preamble for the first time using the random access resources associated with the reference signal includes case one: the terminal device sends a random access preamble for the first time using the random access resources associated with the reference signal and successfully performs LBT. In this case, the terminal device reports to the network side device the first number of times it has continuously sent a random access preamble on the reference signal, and the first number can be 1.
[0072] In some possible implementations, the case where the terminal device sends a random access preamble for the first time using the random access resources associated with the reference signal includes case two: the terminal device sends a random access preamble for the first time using the random access resources associated with the reference signal and fails to perform LBT, thus failing to successfully send the random access preamble. In this case, the terminal device reports to the network-side device the first number of times it has continuously sent the random access preamble on the reference signal. The first number can be 0, or the first number can also be 1, or the first number can also be a predetermined value, etc. This disclosure does not impose specific limitations on this.
[0073] The terminal device may determine the agreed value based on implementation, or based on the protocol agreement, or based on the configuration of the network side device, etc., and this disclosure does not impose specific limitations on this.
[0074] In one embodiment, the terminal device, in response to transmitting a random access preamble using random access resources associated with a reference signal, reports to the network-side device the first number of consecutive transmissions of the random access preamble on the reference signal, including: in response to successfully transmitting the random access preamble using random access resources associated with the reference signal, reporting to the network-side device the first number of consecutive transmissions of the random access preamble on the reference signal.
[0075] In this embodiment of the present disclosure, when the terminal device sends a random access preamble using the random access resources associated with the reference signal, it may report the first number of times the random access preamble is continuously sent on the reference signal to the network-side device only after the random access preamble is successfully sent using the random access resources associated with the reference signal.
[0076] It is understandable that if the terminal device successfully sends the random access preamble using the random access resources associated with the reference signal, it can be understood that the terminal device successfully sends the random access preamble using the random access resources associated with the reference signal, and the LBT corresponding to the transmission of the random access preamble is successful.
[0077] For example, the first number is the sum of the number of times a random access preamble is successfully transmitted on the reference signal and the second number of times a random access preamble is continuously transmitted on the reference signal and the second number of times the transmission is unsuccessful due to LBT failure; or, in the case of the number of times a random access preamble is successfully transmitted on the reference signal, if the terminal device successfully transmits a random access preamble for the first time using the random access resources associated with the reference signal, the terminal device reports the first number of times a random access preamble is continuously transmitted on the reference signal to the network side device, where the first number is 1.
[0078] In some embodiments, before the terminal device reports to the network-side device that it has successfully transmitted the preamble of random access using the random access resources associated with the reference signal, it continuously transmits the preamble of random access on the reference signal, and the second number of unsuccessful transmissions is caused by LBT failure.
[0079] In this embodiment of the present disclosure, when the terminal device successfully transmits the preamble of random access using the random access resources associated with the reference signal, it reports to the network-side device the first number of times the preamble of random access was continuously transmitted on the reference signal. It may also report to the network-side device the second number of times the preamble of random access was continuously transmitted on the reference signal before the preamble of random access was successfully transmitted using the random access resources associated with the reference signal, and the transmission was not successful due to LBT failure.
[0080] For example, taking SSB as the reference signal, if the terminal device first uses the random access resource associated with SSB#1 to send a random access preamble, but LBT failure results in unsuccessful transmission, and then uses the random access resource associated with SSB#1 to send a random access preamble a second time, but LBT failure again results in unsuccessful transmission, and then successfully sends a random access preamble a third time using the random access resource associated with SSB#1, the terminal device can report to the network-side device the first number of consecutive random access preamble transmissions on SSB#1 (the first number is 1), and the second number of consecutive random access preamble transmissions on SSB#1 before successfully sending the random access preamble using the random access resource associated with SSB#1, but LBT failure resulted in unsuccessful transmission (the second number is 2).
[0081] It should be noted that the above examples are for illustrative purposes only and are not intended to limit the specific embodiments of this disclosure. It should be understood that the terminal device may use the same reference signal continuously or may use different reference signals continuously.
[0082] In some embodiments, in response to the terminal device not being configured with lbt-FailureRecoveryConfig, before reporting to the network-side device that the preamble of random access was successfully sent using the random access resource associated with the reference signal, the terminal device continuously sends the preamble of random access on the reference signal, and the second number of unsuccessful transmissions due to LBT failure.
[0083] In this embodiment of the disclosure, the terminal device may continuously transmit the preamble of random access on the reference signal before reporting to the network-side device the preamble of random access using the reference signal associated with the random access resource that was successfully transmitted, and the second number of unsuccessful transmissions caused by LBT failure, only if lbt-FailureRecoveryConfig is not configured.
[0084] Understandably, if a terminal device fails to successfully transmit a random access preamble on any random access resource associated with an SSB or CSI-RS, the terminal device may select one or more of these SSBs / CSI-RS that have attempted to transmit the preamble to report the number of consecutive preamble transmissions on that SSB or CSI-RS.
[0085] In some embodiments, in response to the failure to successfully transmit a random access preamble using the random access resources associated with any of the reference signals, the terminal device selects one or more reference signals and reports to the network-side device the third number of consecutive transmissions of the random access preamble on the selected one or more reference signals.
[0086] In this embodiment of the present disclosure, if the terminal device fails to successfully transmit the preamble of random access using the random access resources associated with any of the reference signals, it selects one or more reference signals and reports to the network-side device the third number of consecutive transmissions of the preamble of random access on the selected one or more reference signals.
[0087] In this process, the terminal device selects one or more reference signals. It may choose to use the random access resources associated with the reference signal to send the reference signal used first in the random access preamble, or it may choose to use the random access resources associated with the reference signal to send the reference signal used last in the random access preamble, or it may choose to use the random access resources associated with the reference signal to send the reference signal used most frequently in the random access preamble, or it may choose to use the random access resources associated with the reference signal to send the reference signal with the worst downlink RSRP (Reference Signal Received Power) in the random access preamble, etc. The embodiments disclosed herein do not impose specific limitations on this.
[0088] In this process, the terminal device selects one or more reference signals. It may select the first one to try, or the last one to try, or the one with the most attempts, or the one with the worst downlink RSRP (Reference Signal Received Power), etc. The embodiments disclosed herein do not impose specific limitations on this.
[0089] For example, when the reference signal is SSB, if the terminal device continuously sends a random access preamble using the random access resources associated with SSB#1, SSB#2, and SSB#3, and fails to successfully send a random access preamble using any of the associated random access resources, it can select one or more from SSB#1, SSB#2, and SSB#3. If SSB#3 is selected, the terminal device can report to the network-side device the third time that a random access preamble has been continuously sent on SSB#3.
[0090] It should be noted that the above examples are for illustrative purposes only and are not intended to limit the specific embodiments of this disclosure. It should be understood that the terminal device may use the same reference signal continuously or may use different reference signals continuously.
[0091] In this embodiment of the disclosure, if the terminal device fails to successfully transmit the preamble of random access using the random access resources associated with any reference signal, it can select one or more reference signals and report to the network-side device the third number of consecutive transmissions of the preamble of random access on the selected one or more reference signals. This is only applicable to connection establishment failure reports, RLF reports caused by handover failure or random access problems, random access reports caused by random access failure, successful handover reports triggered by T304, and SCG failure information reports triggered by random access failure or SCG addition / change.
[0092] In some embodiments, the terminal device, in response to transmitting a random access preamble using random access resources associated with the reference signal, reports to the network-side device the first number of times the random access preamble has been continuously transmitted on the reference signal, including: in response to transmitting a random access preamble using random access resources associated with the reference signal, and the LBT failing to successfully transmit the random access preamble, reporting to the network-side device the first number of times the random access preamble has been continuously transmitted on the reference signal.
[0093] In this embodiment of the present disclosure, when the terminal device sends a random access preamble using the random access resources associated with the reference signal, it reports to the network-side device the first number of times the random access preamble has been continuously sent on the reference signal. This first number of times the random access preamble has been continuously sent on the reference signal is only reported to the network-side device when the random access preamble has been sent using the random access resources associated with the reference signal and the LBT fails to successfully send the random access preamble.
[0094] For example, if the first number is the sum of the number of times the preamble for random access was successfully transmitted on the reference signal and the second number of times the preamble for random access was continuously transmitted on the reference signal and failed to be transmitted due to LBT failure, and the terminal device first uses the random access resources associated with the reference signal to transmit the preamble for random access and fails to transmit the preamble for random access due to LBT failure, the terminal device reports the first number of times the preamble for random access was continuously transmitted on the reference signal to the network side device, where the first number is 1.
[0095] In some embodiments, in response to transmitting a random access preamble using the random access resources associated with the reference signal, the terminal device reports to the network-side device the first number of consecutive transmissions of the random access preamble on the reference signal, and further includes: in response to all random access preambles transmitted using the random access resources associated with the reference signal failing to be successfully transmitted due to LBT failure, reporting to the network-side device the index of the reference signal.
[0096] In this embodiment of the present disclosure, when the terminal device sends a random access preamble using the random access resources associated with the reference signal, it can report to the network-side device the first number of times the random access preamble is continuously sent on the reference signal. The terminal device can also report the index of the reference signal to the network-side device if all random access preambles sent using the random access resources associated with the reference signal fail to be sent successfully via LBT.
[0097] Understandably, if all random access preambles sent by the terminal device using the random access resources associated with the reference signal fail to be successfully sent due to LBT failure, the terminal device will report the index of the reference signal to the network side device and cancel reporting the first number of consecutive random access preambles sent on the reference signal to the network side device.
[0098] In this embodiment of the disclosure, when all random access preambles sent by the terminal device using the random access resources associated with the reference signal fail to be successfully transmitted due to LBT failure, the terminal device reports the index of the reference signal to the network-side device and cancels the reporting of the first number of consecutive random access preambles sent on the reference signal to the network-side device. However, this method cannot use PerRASSBInfo-r16 and PerRACSI-RSInfo-r16 because the preamble count field in these formats is mandatory. Furthermore, their parent IE, PerRAInfo-r16, is also unusable because both are mandatory in the parent IE. Therefore, a new IE, such as PerRAInfo-r18, needs to be defined.
[0099] In some embodiments, the first count is the sum of the number of times a preamble for random access was successfully transmitted on the reference signal and the number of times a preamble for random access was continuously transmitted on the reference signal, and the second count is the number of times a second transmission was unsuccessful due to LBT failure.
[0100] In this embodiment of the present disclosure, when the terminal device sends a random access preamble using the random access resources associated with the reference signal, it reports to the network-side device the first number of times the random access preamble has been sent continuously on the reference signal. The first number is the sum of the number of times the random access preamble has been successfully sent on the reference signal and the second number of times the random access preamble has been sent continuously on the reference signal but failed due to LBT failure.
[0101] For example, taking SSB as the reference signal, if the terminal device successfully sends a random access preamble using the random access resource associated with SSB#1 for the first time and performs LBT, the terminal device reports to the network side device the first number of consecutive transmissions of the random access preamble on SSB#1. The first number can be 1.
[0102] For example, taking CSI-RS as the reference signal, if the terminal device first uses the random access resource associated with CSI-RS#1 to send a random access preamble and fails to perform LBT, and fails to send the random access preamble, the terminal device reports to the network side device the first number of times it has continuously sent the random access preamble on CSI-RS#1. The first number can be 1.
[0103] For example, taking CSI-RS as the reference signal, if the terminal device first uses the random access resource associated with CSI-RS#1 to send a random access preamble and fails to perform LBT, the terminal device reports the first number of consecutive random access preamble transmissions on CSI-RS#1 to the network side device. The first number can be 1. Then, if the terminal device uses the random access resource associated with CSI-RS#1 to send a random access preamble for the second time and successfully performs LBT, the terminal device reports the first number of consecutive random access preamble transmissions on CSI-RS#1 to the network side device. The first number can be 2.
[0104] It should be noted that the above examples are for illustrative purposes only and are not intended to limit the specific embodiments of this disclosure. It should be understood that the terminal device may use the same reference signal continuously or may use different reference signals continuously.
[0105] In some embodiments, the terminal device reports to the network-side device the first number of consecutive transmissions of the preamble for random access on the reference signal, including: the terminal device, without being configured with lbt-FailureRecoveryConfig, reports to the network-side device the first number of consecutive transmissions of the preamble for random access on the reference signal, wherein the first number is the sum of the number of successful transmissions of the preamble for random access on the reference signal and the second number of consecutive transmissions of the preamble for random access on the reference signal that failed due to LBT failure.
[0106] In this embodiment of the disclosure, when the terminal device is not configured with lbt-FailureRecoveryConfig, it reports to the network-side device the first number of times it has continuously sent the preamble of random access on the reference signal. At this time, the first number is the sum of the number of times the preamble of random access was successfully sent on the reference signal and the second number of times the preamble of random access was continuously sent on the reference signal but failed to be sent due to LBT failure.
[0107] Conversely, when the terminal device is configured with lbt-FailureRecoveryConfig, it reports to the network-side device the first number of consecutive transmissions of the random access preamble on the reference signal. Here, the first number is the number of successful transmissions of the random access preamble on the reference signal.
[0108] In this embodiment of the disclosure, for connection establishment failure reports, the terminal device is in an idle or inactive state, and the terminal device is not configured with lbt-FailureRecoveryConfig. Therefore, the first count is the sum of the number of times the preamble of random access was successfully transmitted on the reference signal and the number of times the preamble of random access was continuously transmitted on the reference signal, and the second count of the number of times the transmission was unsuccessful due to LBT failure.
[0109] Understandably, when a terminal device transmits a random access preamble using random access resources associated with a reference signal, it reports to the network-side device the first number of consecutive transmissions of the random access preamble on the reference signal. The first number is the sum of the number of successful transmissions of the random access preamble on the reference signal and the second number of consecutive transmissions of the random access preamble on the reference signal that failed due to LBT failure. At this time, the terminal device can indicate the number of successful transmissions of the random access preamble on the reference signal, or the second number of consecutive transmissions of the random access preamble on the reference signal that failed due to LBT failure, through a new IE (Information Element).
[0110] In some embodiments, the terminal device reports first indication information to the network-side device, wherein the first indication information is used to indicate the number of times a random access preamble is successfully transmitted on the reference signal, or the number of times a random access preamble is continuously transmitted on the reference signal and a second time that the LBT failure results in an unsuccessful transmission.
[0111] In this embodiment of the present disclosure, the terminal device reports first indication information to the network-side device, wherein the first indication information is used to indicate the number of times a random access preamble is successfully transmitted on the reference signal, or the number of times a random access preamble is continuously transmitted on the reference signal and a second time that the LBT failure results in an unsuccessful transmission.
[0112] The first instruction information may be signaling or message in related technologies, or it may be new signaling or message. This disclosure does not impose any specific restrictions on this.
[0113] In some embodiments, the first count is the number of times a preamble for successful random access is transmitted on the reference signal.
[0114] In this embodiment of the present disclosure, when the terminal device sends a random access preamble using the random access resources associated with the reference signal, it reports to the network-side device the first number of times the random access preamble has been sent continuously on the reference signal. The first number is the number of times the random access preamble has been successfully sent on the reference signal.
[0115] The first count does not include the preamble of continuous random access on the reference signal, and the second count is not successfully transmitted due to LBT failure.
[0116] For example, taking SSB as the reference signal, if the terminal device successfully sends a random access preamble using the random access resource associated with SSB#1 for the first time and performs LBT, the terminal device reports to the network side device the first number of consecutive transmissions of the random access preamble on SSB#1. The first number can be 1.
[0117] For example, taking CSI-RS as the reference signal, if the terminal device first uses the random access resource associated with CSI-RS#1 to send a random access preamble and fails to perform LBT, and fails to send the random access preamble, the terminal device reports to the network side device the first number of times it has continuously sent the random access preamble on CSI-RS#1. The first number can be 0.
[0118] For example, taking CSI-RS as the reference signal, if the terminal device first uses the random access resource associated with CSI-RS#1 to send a random access preamble and fails to perform LBT, the terminal device reports the first number of consecutive random access preamble transmissions on CSI-RS#1 to the network side device. The first number can be 0 or a predetermined value. Then, if the terminal device uses the random access resource associated with CSI-RS#1 to send a random access preamble a second time and successfully performs LBT, the terminal device reports the first number of consecutive random access preamble transmissions on CSI-RS#1 to the network side device. The first number can be 1.
[0119] It should be noted that the above examples are for illustrative purposes only and are not intended to limit the specific embodiments of this disclosure. It should be understood that the terminal device may use the same reference signal continuously or may use different reference signals continuously.
[0120] In some embodiments, the terminal device reports to the network-side device the first number of consecutive transmissions of the preamble for random access on the reference signal, including: when the terminal device is configured with lbt-FailureRecoveryConfig, the terminal device reports to the network-side device the first number of consecutive transmissions of the preamble for random access on the reference signal, wherein the first number is the number of times the preamble for random access was successfully transmitted on the reference signal.
[0121] In this embodiment of the disclosure, when the terminal device is configured with lbt-FailureRecoveryConfig, it reports to the network-side device the first number of times it has continuously transmitted the preamble of random access on the reference signal. Here, the first number is the number of times the preamble of random access has been successfully transmitted on the reference signal.
[0122] Understandably, if the first number is the number of times the random access preamble is successfully transmitted on the reference signal, and the terminal device uses the random access resource associated with the reference signal to transmit the random access preamble but fails to perform LBT, thus failing to successfully transmit the random access preamble, the terminal device can use a new IE instruction to continuously transmit the random access preamble on the reference signal, and the LBT failure results in a second number of unsuccessful transmissions.
[0123] In some embodiments, the terminal device reports second indication information to the network-side device, wherein the second indication information is used to indicate the continuous transmission of the preamble of random access on the reference signal, and the second number of unsuccessful transmissions due to LBT failure.
[0124] In this embodiment of the present disclosure, when the terminal device sends a random access preamble using the random access resources associated with the reference signal, it reports to the network-side device the first number of times the random access preamble has been sent continuously on the reference signal. The first number is the number of times the random access preamble has been successfully sent on the reference signal. At this time, if there is a situation where the terminal device sends a random access preamble using the random access resources associated with the reference signal, and the LBT fails, resulting in unsuccessful transmission, the terminal device can report second indication information to the network-side device. The second indication information is used to indicate the second number of times the random access preamble has been sent continuously on the reference signal, and the LBT fails, resulting in unsuccessful transmission.
[0125] Understandably, if the number of successful transmissions of the random access preamble on the reference signal is the first number of times, and the terminal device successfully transmits the random access preamble using the random access resources associated with the reference signal is 0, and the report reported by the terminal device to the network side device must include the PerRAInfoList-r16 field, the terminal device can set numberOfPreamblesSentOnSSB-r16 and numberOfPreamblesSentOnCSI-RS-r16 in PerRAInfoList-r16 to a predetermined value, such as 1, 200, etc., or determine its value based on the terminal device implementation.
[0126] In some embodiments, in response to the number of successful transmissions of the preamble for random access on the reference signal being 0, the terminal device reports a first random access information list to the network-side device, wherein the first random access list includes a first number of times as a predetermined value.
[0127] In this embodiment of the present disclosure, if the number of times the terminal device successfully transmits the preamble of random access on the reference signal is 0, it can report a first random access information list to the network side device, wherein the first random access list includes a first number of times that is a predetermined value.
[0128] The agreed value can be 1, 200, etc., or the terminal device can determine the agreed value based on the implementation, or the terminal device can determine the agreed value based on the network side device configuration, or the terminal device can determine the agreed value based on the protocol agreement, and so on.
[0129] Understandably, when the first count refers to the number of successful transmissions of the preamble for random access on the reference signal, the terminal device can include a newly defined per-pass random access information list, PerRAInfoList (e.g., PerRAInfoList-r18), in the report reported to the network side device. This list contains an IE (Interpretive Information), which can indicate that the number of successful preamble transmissions is 0. This can be indicated by whether the IE is included, by setting the IE to true or false, or by setting the IE to a value within a range including 0, such as [0, 200]. If the number of successfully transmitted preambles is 0, the terminal device sets this field to a value indicating that the number of successful preamble transmissions is 0.
[0130] In some embodiments, the terminal device reports a second random access information list to the network-side device, wherein the second random access list includes an information element IE, which indicates that the number of times the preamble for successful random access has been sent is 0.
[0131] In this embodiment of the present disclosure, when the first number is the number of times a preamble for successful random access is transmitted on the reference signal, the terminal device may report a second random access information list to the network side device. The second random access list includes an information element IE, which is used to indicate that the number of times a preamble for successful random access is transmitted is 0.
[0132] In this embodiment of the disclosure, when the terminal device only needs to report PerRAInfoList-r18 and not PerRAInfoList-r16 (i.e., this field is not mandatory), PerRAInfoList-r18 may contain perRASSBInfoList and perRACSI-RSInfoList. The preamble transmission count in these two lists may contain 0, or the field may be optional; a value of 0 indicates no reporting. This list also contains SSB indexes and CSI-RS indexes.
[0133] In this embodiment of the disclosure, when the terminal device needs to report both PerRAInfoList-r18 and PerRAInfoList-r16 simultaneously, the newly defined PerRAInfoList-r18 can be used in conjunction with PerRAInfoList-r16. That is, the SSB / CSI-RS index corresponding to each item in PerRAInfoList-r18 is the same as the SSB / CSI-RS index of each item in PerRAInfoList-r16. Information already present in each item in PerRAInfoList-r16 does not need to be provided in PerRAInfoList-r18, such as the SSB / CSI-RS index. Each item in PerRAInfoList-r18 only needs to provide other additional information of its corresponding SSB / CSI-RS, such as information indicating that the preamble has been successfully sent 0 times.
[0134] In this embodiment of the disclosure, if the network-side device receives a value in PerRAInfoList-r18 indicating that the number of successful preamble transmissions is 0, the network-side device can ignore numberOfPreamblesSentOnSSB-r16 and numberOfPreamblesSentOnCSI-RS-r16 in PerRAInfoList-r16 sent by the terminal device.
[0135] In this embodiment of the disclosure, the connection establishment failure report, the RLF report caused by handover failure or random access problem, the random access report caused by random access failure, the successful handover report triggered by T304, and the SCG failure information report triggered by random access failure or SCG addition / change, in addition to including the PerRAInfoList-r16 IE, also include the redefined PerRAInfoList IE.
[0136] In this embodiment of the disclosure, for connection establishment failure reporting IE and random access reporting IE, these reporting IEs can be newly defined, which only contain the redefined PerRAInfoList-r18 IE and do not contain the PerRAInfoList-r16 IE.
[0137] In this embodiment of the disclosure, for RLF reports caused by handover failure or random access problems, successful handover reports triggered by T304, and SCG failure information reports triggered by random access failure or SCG addition / change, only the redefined PerRAInfoList-r18 IE is reported, excluding PerRAInfoList-r16 IE. Optionally, PerRAInfoList-r18 IE is only used when the preamble transmission count is 0.
[0138] In some embodiments, the terminal device reports to the network-side device the first number of consecutive transmissions of the preamble for random access on the reference signal, including at least one of the following:
[0139] Report a connection establishment failure report to the network-side device, wherein the connection establishment failure report includes the first number of consecutive transmissions of the preamble for random access on the reference signal;
[0140] Report a random access report to the network-side device, wherein the random access report includes the first number of times the preamble of random access is continuously transmitted on the reference signal;

[0145] Report a PScell success change report to the network-side device. The PScell success change report includes the first number of consecutive transmissions of the preamble for random access on the reference signal.
[0146] In this embodiment of the disclosure, when the terminal device sends a preamble of random access using random access resources associated with the reference signal, it reports to the network-side device the first number of times the preamble of random access is continuously sent on the reference signal, including: reporting a connection establishment failure report to the network-side device, wherein the connection establishment failure report includes the first number of times the preamble of random access is continuously sent on the reference signal.
[0147] In this embodiment of the present disclosure, when a terminal device transmits a preamble of random access using random access resources associated with a reference signal, it reports to the network-side device the first number of times the preamble of random access is continuously transmitted on the reference signal. This includes: reporting a random access report to the network-side device, wherein the random access report includes the first number of times the preamble of random access is continuously transmitted on the reference signal.
[0148] In this embodiment of the present disclosure, when the terminal device transmits a preamble of random access using random access resources associated with a reference signal, it reports to the network-side device the first number of times the preamble of random access is continuously transmitted on the reference signal, including: reporting a Radio Link Failure (RLF) report to the network-side device, wherein the RLF report includes the first number of times the preamble of random access is continuously transmitted on the reference signal.
[0149] In this embodiment of the present disclosure, when the terminal device transmits a preamble of random access using random access resources associated with a reference signal, it reports to the network-side device the first number of times the preamble of random access is continuously transmitted on the reference signal, including: reporting secondary cell group (SCG) failure information to the network-side device, wherein the SCG failure information includes the first number of times the preamble of random access is continuously transmitted on the reference signal.
[0150] In this embodiment of the present disclosure, when the terminal device transmits a random access preamble using random access resources associated with the reference signal, it reports to the network-side device the first number of times the random access preamble has been continuously transmitted on the reference signal, including: reporting a successful handover report to the network-side device, wherein the successful handover report includes the first number of times the random access preamble has been continuously transmitted on the reference signal.
[0151] In this embodiment of the present disclosure, when the terminal device transmits a random access preamble using random access resources associated with the reference signal, it reports to the network-side device the first number of times the random access preamble is continuously transmitted on the reference signal, including: reporting a primary / secondary cell PScell successful addition report to the network-side device, wherein the PScell successful addition report includes the first number of times the random access preamble is continuously transmitted on the reference signal.

[0153] It should be noted that the above embodiments are not exhaustive, but only illustrative of some embodiments. Furthermore, the above embodiments can be implemented individually or in combination. The above embodiments are only illustrative and are not intended to limit the scope of protection of the embodiments disclosed herein.
[0154] In this embodiment of the present disclosure, before the terminal device reports any of the following reports to the network-side device: connection establishment failure report, random access report, RLF report, SCG failure information, successful handover report, PScell successful addition report, and PScell successful change report, it may first record the first number of times the preamble of continuous random access is sent on the reference signal in the variable corresponding to the report. When the network-side device requests the report, the terminal device will then report the report to the network-side device, so as to report the first number of times the preamble of continuous random access is sent on the reference signal to the network-side device.
[0155] In some embodiments, in response to transmitting a random access preamble using random access resources associated with a reference signal with shared spectrum, the terminal device reports to the network-side device the first number of times the random access preamble has been transmitted consecutively on the reference signal.
[0156] In this embodiment of the disclosure, when the terminal device accesses the network-side device using a shared spectrum, it uses the random access resources associated with the reference signal to send a random access preamble and reports to the network-side device the first number of consecutive transmissions of the random access preamble on the reference signal. The description of the first number can be found in the relevant descriptions in the above embodiments, and will not be repeated here.
[0157] In this embodiment of the present disclosure, when the terminal device sends a random access preamble using random access resources associated with a reference signal, it reports to the network-side device the first number of times the random access preamble has been continuously sent on the reference signal. Thus, the network-side device can receive the first number of times the random access preamble has been continuously sent on the reference signal reported by the terminal device. The first number is reported by the terminal device when sending the random access preamble using random access resources associated with a reference signal, and the reference signal is SSB or CSI-RS.
[0158] By implementing embodiments of this disclosure, when a terminal device transmits a random access preamble using random access resources associated with a reference signal, it reports to the network-side device the first number of consecutive transmissions of the random access preamble on the reference signal, wherein the reference signal is an SSB or CSI-RS. Thus, the terminal device supports reporting to the network-side device the first number of consecutive transmissions of the random access preamble on the reference signal when transmitting a random access preamble using random access resources associated with the reference signal.
[0159] Please see Figure 3 , Figure 3 This is a flowchart of another information reporting method provided in this embodiment of the disclosure. For example... Figure 3 As shown, the method may include, but is not limited to, the following steps:
[0160] S31: In response to successfully transmitting a random access preamble using the random access resources associated with the reference signal, the terminal device reports to the network-side device the first number of consecutive transmissions of the random access preamble on the reference signal, wherein the reference signal is SSB or CSI-RS.
[0161] In this embodiment of the disclosure, the terminal device only reports the first number of times it has continuously transmitted the preamble of random access on the reference signal to the network side device when it successfully transmits the preamble of random access using the random access resources associated with the reference signal.
[0162] It is understandable that if the terminal device successfully sends the random access preamble using the random access resources associated with the reference signal, it can be understood that the terminal device successfully sends the random access preamble using the random access resources associated with the reference signal, and the LBT corresponding to the transmission of the random access preamble is successful.
[0163] It should be noted that the first count can be the sum of the number of successful transmissions of the random access preamble on the reference signal and the second count of consecutive transmissions of the random access preamble on the reference signal that failed due to LBT failure; or, the first count can also be the number of successful transmissions of the random access preamble on the reference signal.
[0164] In some embodiments, the first count is the sum of the number of times a preamble for random access was successfully transmitted on the reference signal and the number of times a preamble for random access was continuously transmitted on the reference signal, and the second count is the number of times a second transmission was unsuccessful due to LBT failure.
[0165] In some embodiments, if the terminal device is not configured with lbt-FailureRecoveryConfig, it reports to the network-side device the first number of times it has continuously transmitted the preamble of random access on the reference signal. The first number is the sum of the number of times the preamble of random access was successfully transmitted on the reference signal and the second number of times the preamble of random access was continuously transmitted on the reference signal but failed to be transmitted due to LBT failure.
[0166] In this embodiment of the disclosure, when the terminal device is not configured with lbt-FailureRecoveryConfig, it reports to the network-side device the first number of times it has continuously sent the preamble of random access on the reference signal. At this time, the first number is the sum of the number of times the preamble of random access was successfully sent on the reference signal and the second number of times the preamble of random access was continuously sent on the reference signal but failed to be sent due to LBT failure.
[0167] Conversely, when the terminal device is configured with lbt-FailureRecoveryConfig, it reports to the network-side device the first number of consecutive transmissions of the random access preamble on the reference signal. Here, the first number is the number of successful transmissions of the random access preamble on the reference signal.
[0168] In this embodiment of the disclosure, for connection establishment failure reports, the terminal device is in an idle or inactive state, and the terminal device is not configured with lbt-FailureRecoveryConfig. Therefore, the first count is the sum of the number of times the preamble of random access was successfully transmitted on the reference signal and the number of times the preamble of random access was continuously transmitted on the reference signal, and the second count of the number of times the transmission was unsuccessful due to LBT failure.
[0169] Understandably, when a terminal device transmits a random access preamble using random access resources associated with a reference signal, it reports to the network-side device the first number of consecutive transmissions of the random access preamble on the reference signal. The first number is the sum of the number of successful transmissions of the random access preamble on the reference signal and the second number of consecutive transmissions of the random access preamble on the reference signal that failed due to LBT failure. At this time, the terminal device can indicate the number of successful transmissions of the random access preamble on the reference signal, or the second number of consecutive transmissions of the random access preamble on the reference signal that failed due to LBT failure, through a new IE (Information Element).
[0170] In some embodiments, the terminal device reports first indication information to the network-side device, wherein the first indication information is used to indicate the number of times a random access preamble is successfully transmitted on the reference signal, or the number of times a random access preamble is continuously transmitted on the reference signal and a second time that the LBT failure results in an unsuccessful transmission.
[0171] In this embodiment of the present disclosure, the terminal device reports first indication information to the network-side device, wherein the first indication information is used to indicate the number of times a random access preamble is successfully transmitted on the reference signal, or the number of times a random access preamble is continuously transmitted on the reference signal and a second time that the LBT failure results in an unsuccessful transmission.
[0172] The first instruction information may be signaling or message in related technologies, or it may be new signaling or message. This disclosure does not impose any specific restrictions on this.
[0173] In some embodiments, the first count is the number of times a preamble for successful random access is transmitted on the reference signal.
[0174] In this embodiment of the present disclosure, when the terminal device sends a random access preamble using the random access resources associated with the reference signal, it reports to the network-side device the first number of times the random access preamble has been sent continuously on the reference signal. The first number is the number of times the random access preamble has been successfully sent on the reference signal.
[0175] The first count does not include the preamble of continuous random access on the reference signal, and the second count is not successfully transmitted due to LBT failure.
[0176] In some embodiments, the terminal device reports to the network-side device the first number of consecutive transmissions of the preamble for random access on the reference signal, including: when the terminal device is configured with lbt-FailureRecoveryConfig, the terminal device reports to the network-side device the first number of consecutive transmissions of the preamble for random access on the reference signal, wherein the first number is the number of times the preamble for random access was successfully transmitted on the reference signal.
[0177] In this embodiment of the disclosure, when the terminal device is configured with lbt-FailureRecoveryConfig, it reports to the network-side device the first number of times it has continuously transmitted the preamble of random access on the reference signal. Here, the first number is the number of times the preamble of random access has been successfully transmitted on the reference signal.
[0178] Understandably, if the first number is the number of times the random access preamble is successfully transmitted on the reference signal, and the terminal device uses the random access resource associated with the reference signal to transmit the random access preamble but fails to perform LBT, thus failing to successfully transmit the random access preamble, the terminal device can use a new IE instruction to continuously transmit the random access preamble on the reference signal, and the LBT failure results in a second number of unsuccessful transmissions.
[0179] In some embodiments, the terminal device reports second indication information to the network-side device, wherein the second indication information is used to indicate the continuous transmission of the preamble of random access on the reference signal, and the second number of unsuccessful transmissions due to LBT failure.
[0180] In this embodiment of the present disclosure, when the terminal device sends a random access preamble using the random access resources associated with the reference signal, it reports to the network-side device the first number of times the random access preamble has been sent continuously on the reference signal. The first number is the number of times the random access preamble has been successfully sent on the reference signal. At this time, if there is a situation where the terminal device sends a random access preamble using the random access resources associated with the reference signal, and the LBT fails, resulting in unsuccessful transmission, the terminal device can report second indication information to the network-side device. The second indication information is used to indicate the second number of times the random access preamble has been sent continuously on the reference signal, and the LBT fails, resulting in unsuccessful transmission.
[0181] Understandably, if the number of successful transmissions of the random access preamble on the reference signal is the first number of times, and the terminal device successfully transmits the random access preamble using the random access resources associated with the reference signal is 0, and the report reported by the terminal device to the network side device must include the PerRAInfoList-r16 field, the terminal device can set numberOfPreamblesSentOnSSB-r16 and numberOfPreamblesSentOnCSI-RS-r16 in PerRAInfoList-r16 to a predetermined value, such as 1, 200, etc., or determine its value based on the terminal device implementation.
[0182] In some embodiments, in response to the number of successful transmissions of the preamble for random access on the reference signal being 0, the terminal device reports a first random access information list to the network-side device, wherein the first random access list includes a first number of times as a predetermined value.
[0183] In this embodiment of the present disclosure, if the number of times the terminal device successfully transmits the preamble of random access on the reference signal is 0, it can report a first random access information list to the network side device, wherein the first random access list includes a first number of times that is a predetermined value.
[0184] The agreed value can be 1, 200, etc., or the terminal device can determine the agreed value based on the implementation, or the terminal device can determine the agreed value based on the network side device configuration, or the terminal device can determine the agreed value based on the protocol agreement, and so on.
[0185] Understandably, when the first count refers to the number of successful transmissions of the preamble for random access on the reference signal, the terminal device can include a newly defined per-pass random access information list, PerRAInfoList (e.g., PerRAInfoList-r18), in the report reported to the network side device. This list contains an IE (Interpretive Information), which can indicate that the number of successful preamble transmissions is 0. This can be indicated by whether the IE is included, by setting the IE to true or false, or by setting the IE to a value within a range including 0, such as [0, 200]. If the number of successfully transmitted preambles is 0, the terminal device sets this field to a value indicating that the number of successful preamble transmissions is 0.
[0186] In some embodiments, the terminal device reports a second random access information list to the network-side device, wherein the second random access list includes an information element IE, which indicates that the number of times the preamble for successful random access has been sent is 0.
[0187] In this embodiment of the present disclosure, when the first number is the number of times a preamble for successful random access is transmitted on the reference signal, the terminal device may report a second random access information list to the network side device. The second random access list includes an information element IE, which is used to indicate that the number of times a preamble for successful random access is transmitted is 0.
[0188] In this embodiment of the disclosure, when the terminal device only needs to report PerRAInfoList-r18 and not PerRAInfoList-r16 (i.e., this field is not mandatory), PerRAInfoList-r18 may contain perRASSBInfoList and perRACSI-RSInfoList. The preamble transmission count in these two lists may contain 0, or the field may be optional; a value of 0 indicates no reporting. This list also contains SSB indexes and CSI-RS indexes.
[0189] In this embodiment of the disclosure, when the terminal device needs to report both PerRAInfoList-r18 and PerRAInfoList-r16 simultaneously, the newly defined PerRAInfoList-r18 can be used in conjunction with PerRAInfoList-r16. That is, the SSB / CSI-RS index corresponding to each item in PerRAInfoList-r18 is the same as the SSB / CSI-RS index of each item in PerRAInfoList-r16. Information already present in each item in PerRAInfoList-r16 does not need to be provided in PerRAInfoList-r18, such as the SSB / CSI-RS index. Each item in PerRAInfoList-r18 only needs to provide other additional information of its corresponding SSB / CSI-RS, such as information indicating that the preamble has been successfully sent 0 times.
[0190] In this embodiment of the disclosure, if the network-side device receives a value in PerRAInfoList-r18 indicating that the number of successful preamble transmissions is 0, the network-side device can ignore numberOfPreamblesSentOnSSB-r16 and numberOfPreamblesSentOnCSI-RS-r16 in PerRAInfoList-r16 sent by the terminal device.
[0191] In this embodiment of the disclosure, the connection establishment failure report, the RLF report caused by handover failure or random access problem, the random access report caused by random access failure, the successful handover report triggered by T304, and the SCG failure information report triggered by random access failure or SCG addition / change, in addition to including the PerRAInfoList-r16 IE, also include the redefined PerRAInfoList IE.
[0192] In this embodiment of the disclosure, for connection establishment failure reporting IE and random access reporting IE, these reporting IEs can be newly defined, which only contain the redefined PerRAInfoList-r18 IE and do not contain the PerRAInfoList-r16 IE.
[0193] In this embodiment of the disclosure, for RLF reports caused by handover failure or random access problems, successful handover reports triggered by T304, and SCG failure information reports triggered by random access failure or SCG addition / change, only the redefined PerRAInfoList-r18 IE is reported, excluding PerRAInfoList-r16 IE. Optionally, PerRAInfoList-r18 IE is only used when the preamble transmission count is 0.
[0194] It should be noted that in the embodiments of this disclosure, S31 can be implemented alone or in combination with any other step in the embodiments of this disclosure, such as in combination with S21 in the embodiments of this disclosure. The embodiments of this disclosure do not limit this.
[0195] By implementing embodiments of this disclosure, when a terminal device successfully transmits a random access preamble using random access resources associated with a reference signal, it reports to the network-side device the first number of times the random access preamble has been continuously transmitted on the reference signal, where the reference signal is an SSB or CSI-RS. Thus, the terminal device supports transmitting the first number of times the random access preamble has been continuously transmitted on the reference signal to the network-side device when the random access preamble has been successfully transmitted using random access resources associated with the reference signal.
[0196] Please see Figure 4 , Figure 4 This is a flowchart of another information reporting method provided in this disclosure embodiment. For example... Figure 4 As shown, the method may include, but is not limited to, the following steps:
[0197] S41: In response to successfully transmitting a random access preamble using a random access resource associated with a reference signal, the terminal device reports to the network-side device the first number of consecutive transmissions of the random access preamble on the reference signal, wherein the reference signal is an SSB or a CSI-RS.
[0198] The relevant description of S41 can be found in the relevant description in the above embodiments, and will not be repeated here.
[0199] S42: Before the terminal device reports to the network side device the successful transmission of the random access preamble using the reference signal associated with the random access resource, the terminal device continuously transmits the random access preamble on the reference signal, and the second number of transmissions that fails due to LBT failure.
[0200] In this embodiment of the present disclosure, when the terminal device successfully transmits the preamble of random access using the random access resources associated with the reference signal, it reports to the network-side device the first number of times the preamble of random access was continuously transmitted on the reference signal. It may also report to the network-side device the second number of times the preamble of random access was continuously transmitted on the reference signal before the preamble of random access was successfully transmitted using the random access resources associated with the reference signal, and the transmission was not successful due to LBT failure.
[0201] For example, taking SSB as the reference signal, if the terminal device first uses the random access resource associated with SSB#1 to send a random access preamble, but LBT failure results in unsuccessful transmission, and then uses the random access resource associated with SSB#1 to send a random access preamble a second time, but LBT failure again results in unsuccessful transmission, and then successfully sends a random access preamble a third time using the random access resource associated with SSB#1, the terminal device can report to the network-side device the first number of consecutive random access preamble transmissions on SSB#1 (the first number is 1), and the second number of consecutive random access preamble transmissions on SSB#1 before successfully sending the random access preamble using the random access resource associated with SSB#1, but LBT failure resulted in unsuccessful transmission (the second number is 2).
[0202] It should be noted that the above examples are for illustrative purposes only and are not intended to limit the specific embodiments of this disclosure. It should be understood that the terminal device may use the same reference signal continuously or may use different reference signals continuously.
[0203] It should be noted that the first count can be the sum of the number of successful transmissions of the random access preamble on the reference signal and the second count of consecutive transmissions of the random access preamble on the reference signal that failed due to LBT failure; or, the first count can also be the number of successful transmissions of the random access preamble on the reference signal.
[0204] The method for the terminal device to report the first number of times the preamble of continuous random access on the reference signal is described in the above embodiments and will not be repeated here.
[0205] In some embodiments, when the first number is the sum of the number of successful transmissions of the preamble for random access on the reference signal and the number of second transmissions of the preamble for random access on the reference signal that failed due to LBT failure, the terminal device may also report first indication information to the network-side device, wherein the first indication information is used to indicate the number of successful transmissions of the preamble for random access on the reference signal, or the number of second transmissions of the preamble for random access on the reference signal that failed due to LBT failure.
[0206] The first instruction information may be signaling or message in related technologies, or it may be new signaling or message. This disclosure does not impose any specific restrictions on this.
[0207] In some embodiments, when the first number is the number of times a random access preamble is successfully transmitted on the reference signal, the terminal device may report second indication information to the network-side device, wherein the second indication information is used to indicate the number of consecutive transmissions of the random access preamble on the reference signal, and the second number of times the LBT failure results in a failed transmission.
[0208] In this embodiment of the present disclosure, when the terminal device sends a random access preamble using the random access resources associated with the reference signal, it reports to the network-side device the first number of times the random access preamble has been sent continuously on the reference signal. The first number is the number of times the random access preamble has been successfully sent on the reference signal. At this time, if there is a situation where the terminal device sends a random access preamble using the random access resources associated with the reference signal, and the LBT fails, resulting in unsuccessful transmission, the terminal device can report second indication information to the network-side device. The second indication information is used to indicate the second number of times the random access preamble has been sent continuously on the reference signal, and the LBT fails, resulting in unsuccessful transmission.
[0209] Understandably, if the number of successful transmissions of the random access preamble on the reference signal is the first number of times, and the terminal device successfully transmits the random access preamble using the random access resources associated with the reference signal is 0, and the report reported by the terminal device to the network side device must include the PerRAInfoList-r16 field, the terminal device can set numberOfPreamblesSentOnSSB-r16 and numberOfPreamblesSentOnCSI-RS-r16 in PerRAInfoList-r16 to a predetermined value, such as 1, 200, etc., or determine its value based on the terminal device implementation.
[0210] It should be noted that in the embodiments of this disclosure, S41 and S42 can be implemented individually or in combination with any other step in the embodiments of this disclosure, such as in combination with S21 and / or S31 in the embodiments of this disclosure. The embodiments of this disclosure do not limit this.
[0211] By implementing embodiments of this disclosure, when a terminal device successfully transmits a random access preamble using random access resources associated with a reference signal, it reports to the network-side device the first number of consecutive transmissions of the random access preamble on the reference signal, where the reference signal is an SSB or CSI-RS. The terminal device also reports to the network-side device the second number of consecutive transmissions of the random access preamble on the reference signal that failed due to LBT failure before successfully transmitting the preamble using the random access resources associated with the reference signal. Thus, the terminal device supports both the first number of consecutive transmissions of the random access preamble on the reference signal to the network-side device when successfully transmitting the preamble using the random access resources associated with the reference signal, and the second number of consecutive transmissions of the random access preamble on the reference signal that failed due to LBT failure before successfully transmitting the preamble using the random access resources associated with the reference signal.
[0212] Please see Figure 5 , Figure 5 This is a flowchart of another information reporting method provided in this disclosure embodiment. For example... Figure 5 As shown, the method may include, but is not limited to, the following steps:
[0213] S51: In response to successfully transmitting a random access preamble using a random access resource associated with a reference signal, the terminal device reports to the network-side device the first number of consecutive transmissions of the random access preamble on the reference signal, wherein the reference signal is an SSB or a CSI-RS.
[0214] The relevant description of S51 can be found in the relevant description in the above embodiments, and will not be repeated here.
[0215] S52: If the terminal device is not configured with lbt-FailureRecoveryConfig, before reporting to the network-side device the number of times it continuously sends the random access preamble on the reference signal before successfully sending the random access preamble using the random access resource associated with the reference signal, and the second number of times it fails to send the preamble due to LBT failure.
[0216] In this embodiment of the disclosure, when the terminal device successfully transmits the preamble of random access using the random access resources associated with the reference signal, it reports to the network-side device the first number of times the preamble of random access was continuously transmitted on the reference signal. It can also report to the network-side device, without configuring lbt-FailureRecoveryConfig, the second number of times the preamble of random access was continuously transmitted on the reference signal before the successful transmission of the preamble of random access using the random access resources associated with the reference signal, and the second number of times the transmission was unsuccessful due to LBT failure.
[0217] Specifically, the terminal device can continuously transmit the preamble of random access on the reference signal before successfully transmitting the preamble of random access using the reference signal associated with the random access resource, and the second number of unsuccessful transmissions due to LBT failure, only if lbt-FailureRecoveryConfig is not configured.
[0218] It should be noted that the first count can be the sum of the number of successful transmissions of the random access preamble on the reference signal and the second count of consecutive transmissions of the random access preamble on the reference signal that failed due to LBT failure; or, the first count can also be the number of successful transmissions of the random access preamble on the reference signal.
[0219] The method for the terminal device to report the first number of times the preamble of continuous random access on the reference signal is described in the above embodiments and will not be repeated here.
[0220] The method for continuously transmitting the random access preamble on the reference signal before the terminal device reports to the network side device that the random access resource associated with the reference signal has been successfully transmitted, and for the second number of transmissions that failed due to LBT failure, can be found in the relevant description in the above embodiments, and will not be repeated here.
[0221] It should be noted that in the embodiments of this disclosure, S51 and S52 can be implemented individually or in combination with any other step in the embodiments of this disclosure, such as in combination with S21 and / or S31 and / or S41 and S42 in the embodiments of this disclosure. The embodiments of this disclosure do not limit this.
[0222] By implementing the embodiments of this disclosure, when a terminal device successfully transmits a random access preamble using random access resources associated with a reference signal, it reports to the network-side device the first number of consecutive transmissions of the random access preamble on the reference signal, where the reference signal is an SSB or CSI-RS. Without being configured with lbt-FailureRecoveryConfig, the terminal device can also report to the network-side device a second number of consecutive transmissions of the random access preamble on the reference signal before successfully transmitting it using random access resources associated with the reference signal, where LBT failure resulted in unsuccessful transmission. Therefore, the terminal device supports the first number of consecutive transmissions of the random access preamble on the reference signal when successfully transmitting it using random access resources associated with the reference signal, and, without being configured with lbt-FailureRecoveryConfig, can also report to the network-side device a second number of consecutive transmissions of the random access preamble on the reference signal before successfully transmitting it using random access resources associated with the reference signal, where LBT failure resulted in unsuccessful transmission.
[0223] Please see Figure 6 , Figure 6 This is a flowchart of another information reporting method provided in this disclosure embodiment. For example... Figure 6 As shown, the method may include, but is not limited to, the following steps:
[0224] S61: In response to transmitting a random access preamble using a random access resource associated with a reference signal, the terminal device reports to the network-side device the first number of consecutive transmissions of the random access preamble on the reference signal, wherein the reference signal is an SSB or a CSI-RS.
[0225] The relevant description of S61 can be found in the relevant description in the above embodiments, and will not be repeated here.
[0226] S62: In response to the failure to successfully transmit the preamble of random access using the random access resources associated with any of the reference signals, the terminal device selects one or more reference signals and reports to the network-side device the third number of consecutive transmissions of the preamble of random access on the selected one or more reference signals.
[0227] Understandably, if a terminal device fails to successfully transmit a random access preamble on any random access resource associated with an SSB or CSI-RS, the terminal device may select one or more of these SSBs / CSI-RS that have attempted to transmit the preamble to report the number of consecutive preamble transmissions on that SSB or CSI-RS.
[0228] In this embodiment of the present disclosure, if the terminal device fails to successfully transmit the preamble of random access using the random access resources associated with any of the reference signals, it may select one or more reference signals and report to the network-side device the third number of consecutive transmissions of the preamble of random access on the selected one or more reference signals.
[0229] In this process, the terminal device selects one or more reference signals. It may choose to use the random access resources associated with the reference signal to send the reference signal used first in the random access preamble, or it may choose to use the random access resources associated with the reference signal to send the reference signal used last in the random access preamble, or it may choose to use the random access resources associated with the reference signal to send the reference signal used most frequently in the random access preamble, or it may choose to use the random access resources associated with the reference signal to send the reference signal with the worst downlink RSRP (Reference Signal Received Power) in the random access preamble, etc. The embodiments disclosed herein do not impose specific limitations on this.
[0230] In this process, the terminal device selects one or more reference signals. It may select the first one to try, or the last one to try, or the one with the most attempts, or the one with the worst downlink RSRP (Reference Signal Received Power), etc. The embodiments disclosed herein do not impose specific limitations on this.
[0231] For example, when the reference signal is SSB, if the terminal device continuously sends a random access preamble using the random access resources associated with SSB#1, SSB#2, and SSB#3, and fails to successfully send a random access preamble using any of the associated random access resources, it can select one or more from SSB#1, SSB#2, and SSB#3. If SSB#3 is selected, the terminal device can report to the network-side device the third time that a random access preamble has been continuously sent on SSB#3.
[0232] It should be noted that the above examples are for illustrative purposes only and are not intended to limit the specific embodiments of this disclosure. It should be understood that the terminal device may use the same reference signal continuously or may use different reference signals continuously.
[0233] In this embodiment of the disclosure, if the terminal device fails to successfully transmit the preamble of random access using the random access resources associated with any reference signal, it can select one or more reference signals and report to the network-side device the third number of consecutive transmissions of the preamble of random access on the selected one or more reference signals. This is only applicable to connection establishment failure reports, RLF reports caused by handover failure or random access problems, random access reports caused by random access failure, successful handover reports triggered by T304, and SCG failure information reports triggered by random access failure or SCG addition / change.
[0234] It should be noted that the first count can be the sum of the number of successful transmissions of the random access preamble on the reference signal and the second count of consecutive transmissions of the random access preamble on the reference signal that failed due to LBT failure; or, the first count can also be the number of successful transmissions of the random access preamble on the reference signal.
[0235] The method for the terminal device to report the first number of times the preamble of continuous random access on the reference signal is described in the above embodiments and will not be repeated here.
[0236] It should be noted that in the embodiments of this disclosure, S61 and S62 can be implemented individually or in combination with any other step in the embodiments of this disclosure, such as in combination with S21 and / or S31 and / or S41 and S42 and / or S51 and S52 in the embodiments of this disclosure. The embodiments of this disclosure do not limit this.
[0237] By implementing embodiments of this disclosure, a terminal device transmits a random access preamble using random access resources associated with a reference signal, and reports to the network-side device the first number of consecutive transmissions of the random access preamble on the reference signal, wherein the reference signal is an SSB or CSI-RS. If the terminal device fails to successfully transmit the random access preamble using any random access resource associated with the reference signal, it selects one or more reference signals and reports to the network-side device the third number of consecutive transmissions of the random access preamble on the selected one or more reference signals. Thus, the terminal device supports the first number of consecutive transmissions of the random access preamble on the reference signal when transmitting the preamble using random access resources associated with the reference signal, and the third number of consecutive transmissions of the random access preamble on the selected one or more reference signals when failing to successfully transmit the preamble using any random access resource associated with the reference signal.
[0238] Please see Figure 7 , Figure 7 This is a flowchart of another information reporting method provided in this disclosure embodiment. For example... Figure 7 As shown, the method may include, but is not limited to, the following steps:
[0239] S71: In response to the terminal device transmitting a random access preamble using a random access resource associated with a reference signal, and the LBT failing to successfully transmit the random access preamble, the terminal device reports to the network-side device the first number of consecutive transmissions of the random access preamble on the reference signal, wherein the reference signal is an SSB or a CSI-RS.
[0240] In this embodiment of the present disclosure, the terminal device may report the first number of times the preamble of random access was continuously transmitted on the reference signal only if the preamble of random access is transmitted using the random access resources associated with the reference signal and the LBT fails to successfully transmit the preamble of random access.
[0241] It should be noted that the first count can be the sum of the number of successful transmissions of the random access preamble on the reference signal and the second count of consecutive transmissions of the random access preamble on the reference signal that failed due to LBT failure; or, the first count can also be the number of successful transmissions of the random access preamble on the reference signal.
[0242] The method for the terminal device to report the first number of times the preamble of continuous random access on the reference signal is described in the above embodiments and will not be repeated here.
[0243] It should be noted that in the embodiments of this disclosure, S71 can be implemented alone or in combination with any other step in the embodiments of this disclosure, such as in combination with S21 and / or S61 and S62 in the embodiments of this disclosure. The embodiments of this disclosure do not limit this.
[0244] By implementing embodiments of this disclosure, when a terminal device transmits a random access preamble using random access resources associated with a reference signal, and the LBT fails to successfully transmit the random access preamble, the terminal device reports to the network-side device the first number of consecutive transmissions of the random access preamble on the reference signal, wherein the reference signal is an SSB or CSI-RS. Therefore, the terminal device supports reporting to the network-side device the first number of consecutive transmissions of the random access preamble on the reference signal when transmitting a random access preamble using random access resources associated with a reference signal, and the LBT fails to successfully transmit the random access preamble.
[0245] Please see Figure 8 , Figure 8 This is a flowchart of another information reporting method provided in this disclosure embodiment. For example... Figure 8 As shown, the method may include, but is not limited to, the following steps:
[0246] S81: In response to sending a random access preamble using a random access resource associated with a reference signal, the terminal device reports to the network-side device the first number of consecutive transmissions of the random access preamble on the reference signal, wherein the reference signal is an SSB or a CSI-RS.
[0247] The relevant description of S81 can be found in the relevant description in the above embodiments, and will not be repeated here.
[0248] The method for the terminal device to report the first number of times the preamble of continuous random access on the reference signal is described in the above embodiments and will not be repeated here.
[0249] S82: In response to the failure of LBT to successfully transmit all random access preambles sent using the random access resources associated with the reference signal, the terminal device reports the index of the reference signal to the network side device.
[0250] In this embodiment of the present disclosure, when the terminal device sends a random access preamble using the random access resources associated with the reference signal, it can report to the network-side device the first number of times the random access preamble is continuously sent on the reference signal. The terminal device can also report the index of the reference signal to the network-side device if all random access preambles sent using the random access resources associated with the reference signal fail to be sent successfully via LBT.
[0251] Understandably, if all random access preambles sent by the terminal device using the random access resources associated with the reference signal fail to be successfully sent due to LBT failure, the terminal device will report the index of the reference signal to the network side device and cancel reporting the first number of consecutive random access preambles sent on the reference signal to the network side device.
[0252] In this embodiment of the disclosure, when all random access preambles sent by the terminal device using the random access resources associated with the reference signal fail to be successfully transmitted due to LBT failure, the terminal device reports the index of the reference signal to the network-side device and cancels the reporting of the first number of consecutive random access preambles sent on the reference signal to the network-side device. However, this method cannot use PerRASSBInfo-r16 and PerRACSI-RSInfo-r16 because the preamble count field in these formats is mandatory. Furthermore, their parent IE, PerRAInfo-r16, is also unusable because both are mandatory in the parent IE. Therefore, a new IE, such as PerRAInfo-r18, needs to be defined.
[0253] It should be noted that in the embodiments of this disclosure, S81 and S82 can be implemented individually or in combination with any other step in the embodiments of this disclosure, such as in combination with S21 and / or S31 and / or S41 and S42 and / or S51 and S52 and / or S61 and S62 and / or S71 in the embodiments of this disclosure. The embodiments of this disclosure do not limit this.
[0254] By implementing the embodiments of this disclosure, when a terminal device transmits a random access preamble using random access resources associated with a reference signal, it reports to the network-side device the first number of consecutive transmissions of the random access preamble on the reference signal, wherein the reference signal is an SSB or CSI-RS. The terminal device can also report the index of the reference signal to the network-side device if all random access preambles transmitted using random access resources associated with the reference signal fail to transmit via LBT. Therefore, the terminal device supports reporting the first number of consecutive transmissions of the random access preamble on the reference signal to the network-side device when transmitting a random access preamble using random access resources associated with the reference signal, and reporting the index of the reference signal to the network-side device if all random access preambles transmitted using random access resources associated with the reference signal fail to transmit via LBT.
[0255] Please continue reading Figure 2 In this embodiment of the disclosure, the information reporting method performed by the network-side device includes:
[0256] S21: Receive the first number of times the terminal device continuously transmits the preamble of random access on the reference signal, where the first number is reported by the terminal device when transmitting the preamble of random access using the random access resources associated with the reference signal, and the reference signal is SSB or CSI-RS.
[0257] like Figure 3 As shown, in some embodiments, the first number is reported by the terminal device when it successfully sends the preamble of random access using the random access resources associated with the reference signal.
[0258] like Figure 4 As shown, in some embodiments, the network-side device also receives a second number of consecutive transmissions of the random access preamble on the reference signal before the terminal device successfully transmits the random access preamble using the random access resource associated with the reference signal, and the LBT failure causes the transmission to fail.
[0259] like Figure 5 As shown, in some embodiments, the second number is reported by the terminal device when lbt-FailureRecoveryConfig is not configured.
[0260] like Figure 6As shown, in some embodiments, the network-side device also receives a third number reported by the terminal device for the continuous transmission of the preamble of random access on one or more selected reference signals, wherein the third number is reported by the terminal device when it fails to successfully transmit the preamble of random access using the random access resources associated with any of the reference signals and selects one or more from the reference signals.
[0261] like Figure 7 As shown, in some embodiments, the first number is reported by the terminal device when it sends a random access preamble using the random access resources associated with the reference signal, and the LBT fails to successfully send the random access preamble.
[0262] like Figure 8 As shown, in some embodiments, the network-side device also receives an index of a reference signal reported by the terminal device. The index of the reference signal is reported by the terminal device when all random access preambles sent by the terminal device using the random access resources associated with the reference signal fail to be successfully sent due to LBT failure.
[0263] In some embodiments, the first count is the sum of the number of times a preamble for random access was successfully transmitted on the reference signal and the number of times a preamble for random access was continuously transmitted on the reference signal, and the second count is the number of times a second transmission was unsuccessful due to LBT failure.
[0264] In some embodiments, the first count is reported by the terminal device when lbt-FailureRecoveryConfig is not configured.
[0265] In some embodiments, the network-side device receives first indication information reported by the terminal device, wherein the first indication information is used to indicate the number of times a random access preamble is successfully transmitted on the reference signal, or the number of times a random access preamble is continuously transmitted on the reference signal, and the second time that LBT failure results in unsuccessful transmission.
[0266] In some embodiments, the first count is the number of times a preamble for successful random access is transmitted on the reference signal.
[0267] In some embodiments, the first number is reported by the terminal device when lbt-FailureRecoveryConfig is configured.
[0268] In some embodiments, the network-side device receives second indication information reported by the terminal device, wherein the second indication information is used to indicate the continuous transmission of the preamble of random access on the reference signal, and the second number of unsuccessful transmissions due to LBT failure.
[0269] In some embodiments, the network-side device receives a first number of times a preamble for continuous random access is transmitted on a reference signal, reported by the terminal device, including: receiving a first random access information list reported by the terminal device, wherein the first random access information list is reported when the number of times the terminal device successfully transmits a preamble for random access on the reference signal is 0, and the first random access list includes a first number of times as a predetermined value.
[0270] In some embodiments, the network-side device receiving the first number of consecutive transmissions of the preamble of random access on the reference signal reported by the terminal device includes: receiving the second random access information list reported by the terminal device, wherein the second random access list includes an information element IE, which is used to indicate that the number of successful transmissions of the preamble of random access is 0.
[0271] In some embodiments, the network-side device receives a first number of consecutive transmissions of the preamble for random access on the reference signal reported by the terminal device, including at least one of the following:
