[0034] The method disclosed herein can be used to solve the technical problem of "how to successfully report consecutive LBT failure reports".

[0035] The embodiments of the present disclosure provide a communication method and apparatus, a communication device, a communication system, and a storage medium.

[0036] In a first aspect, an embodiment of the present disclosure provides a communication method, the method comprising:

[0037] A first condition is met, triggering first information, where the first information is used to request uplink resources;

[0038] If the second condition is met, the first information is cancelled.

[0039] In the above embodiment, the terminal will execute at least one of the two steps of "triggering the first information to request uplink resources when the first condition is met, and canceling the first information when the second condition is met". It can be seen that in the embodiment of the present disclosure, the triggering condition and cancellation condition of the first information are defined, and the triggering time and end time of the process of the terminal requesting uplink resources are clarified, so that the terminal can know when to trigger the first information to request uplink resources and when to cancel the first information to cancel the request for uplink resources, ensuring that the terminal can successfully execute the uplink resource request process and ensure that the terminal can successfully request uplink resources, so that the terminal can use the requested uplink resources to report continuous LBT failure reports, ensuring the successful reporting of continuous LBT failure reports.

[0040] In conjunction with some embodiments of the first aspect, in some embodiments, after the triggering first information, the method further includes:

[0041] The first information is sent.

[0042] In the above embodiment, after the terminal triggers the first information, the first information will be sent so that the network device can successfully receive the first information and can successfully schedule uplink resources to the terminal based on the first information, so that the terminal can successfully request uplink resources. The terminal can then use the requested uplink resources to report continuous LBT failure reports, ensuring the successful reporting of continuous LBT failure reports.

[0043] In conjunction with some embodiments of the first aspect, in some embodiments, the first condition includes at least one of the following:

[0044] The terminal detects that at least one first resource triggers a sidelink (SL) continuous listen-before-talk (LBT) failure;

[0045] The terminal detects that at least one first resource triggers a SL continuous LBT failure and the SL continuous LBT failure is not cancelled;

[0046] There is no available uplink resource to send second information, where the second information is used to indicate that the at least one first resource triggers SL continuous LBT failure;

[0047] The terminal is in a first mode, where the first mode is: a network device allocates resources to the terminal;

[0048] The terminal is in a second mode and is in a radio resource control RRC connected state, and the second mode is: the terminal autonomously determines resources.

[0049] In the above embodiment, the specific content of the first condition is limited, and the triggering time of the uplink resource request process is clarified, so that the terminal can know when to trigger the first information to request uplink resources, ensuring that the terminal can successfully request uplink resources, so that the terminal can use the requested uplink resources to report continuous LBT failure reports, ensuring the successful reporting of continuous LBT failure reports.

[0050] In conjunction with some embodiments of the first aspect, in some embodiments, the second condition includes at least one of the following:

[0051] The second information is sent successfully, and the second information is used to indicate that the at least one first resource triggers SL continuous LBT failure;

[0052] At least one first resource-triggered SL continuous LBT failure is canceled.

[0053] In the above embodiment, the specific content of the second condition is limited, and the end time of the uplink resource request process is clarified, so that the terminal can know when to cancel the first information to stop requesting uplink resources, ensuring that the terminal can successfully stop the uplink resource request process, avoiding unlimited execution of the uplink resource request process, and preventing waste of resources.

[0054] With reference to some embodiments of the first aspect, in some embodiments, the triggering first information includes:

[0055] The first information is triggered correspondingly for at least one first resource that meets the first condition.

[0056] In the above embodiment, for each first resource that meets the first condition, the terminal will independently trigger the first information. It can be seen that in the embodiment of the present disclosure, for each first resource that meets the first condition, the uplink resource request process will be independently triggered, which can prevent mutual interference between the uplink resource request processes of different first resources and improve the robustness of the uplink resource request process.

[0057] In conjunction with some embodiments of the first aspect, in some embodiments, canceling the first information includes:

[0058] The first information triggered by the first resource that meets the second condition is canceled.

[0059] In the above embodiment, for each first resource that meets the second condition, the terminal will independently cancel the first information respectively. It can be seen that in the embodiment of the present disclosure, for each first resource that meets the second condition, the uplink resource request process previously triggered accordingly will be stopped independently, which can prevent mutual interference between the uplink resource request processes of different first resources and improve the robustness of the uplink resource request process.

[0060] With reference to some embodiments of the first aspect, in some embodiments, sending the first information includes:

[0061] Sending first information triggered by one or more first resources respectively.

[0062] In the above embodiment, the terminal will independently send the first information triggered by each first resource. It can be seen that in the embodiment of the present disclosure, the uplink resource request process will be independently executed for each first resource that triggers the first information, which can prevent mutual interference between the uplink resource request processes of different first resources and improve the robustness of the uplink resource request process.

[0063] In conjunction with some embodiments of the first aspect, in some embodiments, the method further includes:

[0064] Start a first timer; wherein, the first timer is a timer associated with the first information, and while the first timer is in the started state, the first information is prohibited from being sent.

[0065] In the above embodiment, since the first information is prohibited from being sent when the first timer is started, by executing the step of "starting the first timer after the terminal sends the first information", the first information can be prevented from being frequently sent in a short period of time, thereby saving resources.

[0066] In conjunction with some embodiments of the first aspect, in some embodiments, after canceling the first information, the method further includes:

[0067] The first timer is in the on state, and the first timer is stopped; wherein the first timer is a timer associated with the first information, and while the first timer is in the on state, the first information is prohibited from being sent.

[0068] In the above embodiment, after the terminal cancels the first information, if the first timer associated with the first information is in the on state, the first timer will be stopped. Since the first information is prohibited from being sent when the first timer is on, the first timer associated with the canceled first information is stopped to ensure that when the terminal triggers the first information again, the re-triggered first information can be successfully sent, thereby ensuring that the terminal can successfully request uplink resources in the future, so that the terminal can use the requested uplink resources to report the continuous LBT failure report, thereby ensuring the successful reporting of the continuous LBT failure report.

[0212] To facilitate understanding, the terms involved in this disclosure are first introduced.

[0213] 1. Listen-Before-Talk (LBT)

[0214] LBT is a widely used technology in radio communications. Before starting transmission, the radio transmitter first listens to its radio environment to detect whether the channel is idle. If the channel is busy, it waits until the channel is idle before transmitting, avoiding channel access conflicts and achieving channel spectrum sharing.

[0215] 2. Sidelink (SL)

[0216] A link for direct communication between end devices.

[0217] In an embodiment of the present disclosure, the terminal may detect whether its resources have triggered SL continuous LBT failure. Optionally, the method for the terminal to detect whether its resources have triggered SL continuous LBT failure may include the steps of:

[0218] Step 1: The terminal obtains the second timer and the first value configured by the network device;

[0219] Optionally, the name of the second timer is not limited, and it can be, for example, "SL LBT failure detection timer", "sl-Lbt-FailureDetectionTimer", etc.; the name of the first value is not limited, and it can be, for example, "maximum number of LBT failures", "sl-Lbt-FailureInstanceMaxCount", etc.

[0220] Optionally, the second timer and the first value can be configured by the network device through a first signaling. Optionally, the name of the first signaling is not limited, and it can be, for example, "Radio Resource Control (RRC) signaling", etc. Optionally, the RRC signaling can be, for example: sl-Lbt-FailureRecoveryConfig.

[0221] Step 2: The terminal maintains a count value, the initial value of which is 0.

[0222] Optionally, the name of the count value is not limited, and it can be, for example, "SL LBT count value", "SL LBT_counter", etc.

[0223] Step 3: The terminal detects whether its resources have SL LBT failures, and records the number of consecutive SL LBT failures of the terminal resources by updating the count value, thereby further determining whether the resources have triggered SL consecutive LBT failures.

[0224] Optionally, the method for a terminal to detect whether an SL LBT failure occurs in its resources may include: the terminal performs an SL LBT detection on the resource; if the terminal does not receive an SL LBT failure indication (such as the terminal's upper layer does not receive an SL LBT failure indication sent by the terminal's physical layer), it is determined that an SL LBT failure occurs in the resource; if the terminal receives an SL LBT failure indication (such as the terminal's upper layer receives an SL LBT failure indication sent by the terminal's physical layer), it is determined that an SL LBT failure occurs in the resource. Optionally, in some embodiments, the occurrence of the above-mentioned SL LBT failure may be understood as: the terminal does not detect any idle resources available for transmission in the resource; for example, the terminal does not detect any idle resources available for SL transmission in the resource.

[0225] Optionally, the method for a terminal to record the number of SL LBT failures that occur on its resources may include: when the terminal detects that a SL LBT failure occurs on a certain resource for the first time, the terminal will start a second timer and add 1 to the count value; when the terminal detects that a SL LBT failure occurs on the resource for the second time during the activation period of the second timer, the terminal will restart the second timer and add 1 to the count value again, and so on to update the count value. When the count value is greater than or equal to the first value, the terminal considers that the resource has triggered a continuous SL LBT failure.

[0226] Optionally, in some embodiments, when the terminal satisfies a third condition, the count value is reset to 0. Optionally, the third condition may include at least one of the following:

[0227] The second timer times out;

[0228] The terminal receives at least one of the second timer and the first value reconfigured by the network device;

[0229] The SL LBT failure triggered by the terminal on this resource is canceled.

[0230] Optionally, in some embodiments, the above-mentioned "resource-triggered SL LBT failure is canceled" can be understood as follows: after the resource triggers the SL continuous LBT failure, the terminal determines that the received signal strength indication (RSSI) measurement result of the resource is less than or equal to a preset threshold, thereby canceling the SL continuous LBT failure triggered by the resource. Optionally, there may be other methods for canceling the SL continuous LBT failure, which are not specifically limited in this disclosure.

[0231] By executing the above steps 1 to 3, the detection of SL continuous LBT failure can be achieved.

[0232] Optionally, in some embodiments, for a terminal operating in the first mode or the second mode but in an RRC connected state, when the terminal determines that its resources have triggered a SL continuous LBT failure, it indicates that the terminal currently has no available SL resources for SL communication. In this case, the terminal typically reports an SL continuous LBT failure report to the network device. Optionally, the first mode described above may be: the network device allocates resources to the terminal. Optionally, the name of the first mode is not limited, and it may be, for example, "mode 1 mode"; the second mode is: the terminal autonomously determines resources, for example, the terminal may randomly select resources from a resource pool configured or pre-configured by the network device. Optionally, the name of the second mode is not limited, and it may be, for example, "mode 2 mode". Optionally, the method for the terminal to report an SL continuous LBT failure report to the network device may be, for example, sending a first indication to the network device, where the first indication is used to indicate that the terminal's resources have triggered a SL continuous LBT failure. Optionally, after receiving the first indication, the network device may configure other available resources for the terminal by reconfiguring resources, etc., to ensure that the terminal resumes SL communication based on the resources reconfigured by the network device.

[0233] Optionally, in some embodiments, when the terminal determines that its resources have triggered SL continuous LBT failure, there may be a situation where "there are no available uplink resources to send the first indication". At this time, the terminal needs to send a first message to the network device. The first message is used to request the network device for uplink resources used to send the first indication. The name of the first message is not limited, and it can be, for example: Scheduling Request (SR), resource request, etc.

[0234] FIG2A is an interactive diagram of a communication method according to an embodiment of the present disclosure. As shown in FIG2A , the embodiment of the present disclosure relates to a communication method for use in a communication system 100, the method comprising:

[0235] Step 2101: trigger the first information.

[0236] Optionally, in some embodiments, the first information may be used to request uplink resources.

[0237] Optionally, in some embodiments, the first information may be triggered when the terminal meets the first condition.

[0238] Optionally, in some embodiments, the first condition may include at least one of the following:

[0239] The terminal detects that at least one first resource triggers a SL continuous LBT failure and the SL continuous LBT fails;

[0240] The terminal detects that at least one first resource triggers a SL continuous LBT failure and the SL continuous LBT failure is not canceled;

[0241] There are no available uplink resources to send the second information, optionally, the second information is used to indicate that at least one first resource has triggered an SL continuous LBT failure, or the second information is used to indicate that at least one first resource has triggered an SL continuous LBT failure and the SL continuous LBT failure has not been canceled; optionally, the second information is used by the terminal to report an SL continuous LBT failure report to the network device;

[0242] The terminal is in a first mode. Optionally, the first mode may be: resources are allocated to the terminal by a network device. Optionally, the name of the first mode is not limited, and may be, for example, "mode 1 mode" or the like;

[0243] The terminal is in the second mode and the terminal is in the RRC connection state. Optionally, the second mode is: the terminal autonomously determines resources, for example, the terminal can randomly select resources from the network device configuration or pre-configured resource pool. Optionally, the name of the second mode is not limited, and it can be, for example, "mode 2 mode" or the like.

[0244] Optionally, in some embodiments, the first condition may be: the terminal detects that at least one first resource triggers a SL continuous LBT failure, and the terminal is in the first mode; or, the first condition may be: the terminal detects that at least one first resource triggers a SL continuous LBT failure, the terminal is in the second mode, and the terminal is in the RRC connected state;

[0245] In some other embodiments, the first condition may be: the terminal detects that at least one first resource triggers a SL continuous LBT failure and the SL continuous LBT failure is not canceled, and the terminal is in the first mode; or, the first condition may be: the terminal detects that at least one first resource triggers a SL continuous LBT failure and the SL continuous LBT failure is not canceled, the terminal is in the second mode, and the terminal is in the RRC connected state;

[0246] In some further embodiments, the first condition may be: the terminal detects that at least one first resource triggers a SL continuous LBT failure, there are no available uplink resources to send the second information, and the terminal is in the first mode; or, the first condition may be: the terminal detects that at least one first resource triggers a SL continuous LBT failure, there are no available uplink resources to send the second information, the terminal is in the second mode, and the terminal is in an RRC connected state;

[0247] In some other embodiments, the first condition may be: the terminal detects that at least one first resource triggers a SL continuous LBT failure and the SL continuous LBT failure is not canceled, there are no available uplink resources to send the second information, and the terminal is in the first mode; or, the first condition may be: the terminal detects that at least one first resource triggers a SL continuous LBT failure and the SL continuous LBT failure is not canceled, there are no available uplink resources to send the second information, the terminal is in the second mode, and the terminal is in an RRC connected state.

[0248] Optionally, in some embodiments, the reason for introducing "the terminal is in the first mode, the terminal is in the second mode and the terminal is in the RRC connected state" in the above-mentioned first condition is that: when the terminal is in the first mode, or, in the second mode but in the RRC connected state, it means that the terminal can currently communicate with the network device, or, it means that the terminal can currently send uplink to the network device. Therefore, at this time, if the terminal meets at least one of "detecting that at least one first resource has triggered a SL continuous LBT failure and the SL continuous LBT failure, detecting that at least one first resource has triggered a SL continuous LBT failure and the SL continuous LBT failure has not been canceled, and there are no available uplink resources to send the second information", on the premise that the terminal can currently communicate with the network device, the terminal can trigger the first information so that the terminal can subsequently successfully send the triggered first information to the network device to request uplink resources.

[0249] The following is an explanation of the meaning of the terms mentioned in the first condition above.

[0250] Optionally, in some embodiments, the above-mentioned first resource may be used for the terminal to perform SL communication. Optionally, the first resource may include at least one of a resource block set (RB set), a bandwidth part (BWP), and a resource pool.

[0251] Optionally, the aforementioned "continuous SL LBT failure" can be understood as, for example, continuous LBT failure for SL communication. For example, when the terminal detects that the first resource used for SL communication has triggered continuous LBT failure, the terminal considers that the first resource has triggered "continuous SL LBT failure." For a detailed introduction to "continuous LBT failure," please refer to the description of steps 1 to 3 above.

[0252] Optionally, in some embodiments, the above-mentioned "the SL continuous LBT failure triggered by the first resource is not canceled" can be understood as: after the first resource triggers the SL continuous LBT failure, the SL continuous LBT failure triggered by the first resource is not canceled. For example, after the first resource triggers the SL continuous LBT failure, the terminal determines that the RSSI measurement result of the first resource is not less than or equal to the preset threshold, and thus the SL continuous LBT failure triggered by the first resource will not be canceled. Optionally, the reason for not canceling the SL continuous LBT failure may also be other reasons, which are not specifically limited in this disclosure.

[0253] Optionally, in some embodiments, the second information mentioned in the above-mentioned first condition can be used to indicate that at least one first resource has triggered a SL continuous LBT failure, or, the second information can be used to indicate that at least one first resource has triggered a SL continuous LBT failure and the SL continuous LBT failure has not been canceled.

[0254] Optionally, in some embodiments, the second information may include a first indication, where the first indication may be used to indicate that at least one first resource has triggered a SL continuous LBT failure, or to indicate that at least one first resource has triggered a SL continuous LBT failure and the SL continuous LBT failure has not been canceled;

[0255] In other embodiments, the second information may indicate to the network device that at least one first resource has triggered a SL continuous LBT failure by indicating the first resource that has triggered a SL continuous LBT failure, or indicate that at least one first resource has triggered a SL continuous LBT failure and the SL continuous LBT failure has not been canceled. For example, in some embodiments, the second information may include an identifier corresponding to the first resource that has triggered the SL continuous LBT failure.

[0256] In some further embodiments, the second information may include a bitmap, wherein each bit in the bitmap corresponds to a first resource, and the bit value carried by the bit in the bitmap is used to indicate whether the corresponding first resource triggers SL continuous LBT failure. For example, when the bit value carried by the bit in the bitmap is a first value, it indicates that the corresponding first resource has triggered SL continuous LBT failure or has triggered SL continuous LBT failure and has not canceled the SL continuous LBT failure. When the bit value carried by the bit in the bitmap is a second value, it indicates that the corresponding first resource has not triggered SL continuous LBT failure or has triggered SL continuous LBT failure and the triggered SL continuous LBT failure has been canceled. Optionally, the first value may be, for example, "1", and the second value may be, for example, "0".

[0257] Optionally, in some embodiments, the second information may be Media Access Control Random Access Response (MAC) layer signaling. For example, the second information may be Media Access Control Control Element (MAC CE) signaling, such as: "MAC CE containing SL continuous LBT failure indication." It should be understood that the second information may also be other MAC layer signaling in addition to MAC CE signaling, which is not limited in this disclosure. Optionally, the second information may be carried by a Media Access Control Protocol Data Unit (MAC PDU).

[0258] In some embodiments, the name of the second information is not limited, and may be, for example, "SL continuous LBT failure MAC CE", "SL continuous LBT failure information", "continuous LBT failure information", etc. The name of the first indication is not limited, and may be, for example, "SL continuous LBT failure indication", "continuous LBT failure indication", etc.

[0259] Optionally, in some embodiments, the aforementioned “no uplink resources available to send the second information” may include at least one of the following:

[0260] No uplink new transmission resources are available;

[0261] There are available uplink new transmission resources, but the available uplink new transmission resources cannot include the second information and the subheader of the second information. For example, when the second information is a MAC CE, the available uplink new transmission resources cannot include the MAC CE and the subheader of the MAC CE.

[0262] Optionally, in some embodiments, when the terminal meets the first condition, it indicates that the first resource of the terminal cannot be used for SL communication due to triggering the SL continuous LBT failure, and the terminal is currently unable to report the SL continuous LBT failure report due to the lack of available uplink resources. At this time, the terminal can trigger the first information, which can be used to request uplink resources so that the terminal can subsequently use the requested uplink resources to successfully report the SL continuous LBT failure report.

[0263] Optionally, in some embodiments, the above-mentioned “triggering the first information” may be understood as: the terminal generates the first information and places the first information in a waiting-to-send state.

[0264] Optionally, in some embodiments, the triggering first information may include: triggering the first information corresponding to at least one first resource that meets the first condition.

[0265] For example, assuming that the terminal has two first resources, namely first resource #1 and first resource #2, wherein assuming that the terminal successively detects that the first resource #1 and the first resource #2 trigger SL continuous LBT failure and the SL continuous LBT failure is not canceled, and there is no available uplink resource to send the second information, then the first information #1 can be triggered for the first resource #1 first (that is, the first information #1 is generated, and the first information #1 is placed in a waiting-to-send state), and then the first information #2 can be triggered for the first resource #2 (that is, the first information #2 is generated, and the first information #2 is placed in a waiting-to-send state).

[0266] Optionally, in some embodiments, the above-mentioned "trigger" may be equivalent to "generate". It should be understood that the above-mentioned "trigger" and "generate" are only illustrative examples of the embodiments of the present disclosure, and other nouns with similar meanings to "trigger" and "generate" (such as "produce", "enable", etc.) are also within the scope of protection of the present disclosure. Optionally, in some embodiments, the name of the above-mentioned first information is not limited, and it can be, for example, "SR", "resource request", "resource scheduling request", etc. The name of the above-mentioned first timer is also not limited, and it can be, for example, "SR prohibit timer", "sr-ProhibitTimer", "prohibit timer", etc.

[0267] In some embodiments, the names of information, etc. are not limited to the names described in the embodiments, and terms such as "information", "message", "signal", "signaling", "report", "configuration", "indication", "instruction", "command", "channel", "parameter", "domain", "field", "symbol", "symbol", "codeword", "codebook", "codeword", "codepoint", "bit", "data", "program", and "chip" can be used interchangeably.

[0268] In some embodiments, terms such as "uplink", "uplink", "physical uplink" can be interchangeable with each other, and terms such as "downlink", "downlink", "physical downlink" can be interchangeable with each other, and terms such as "side", "sidelink", "side communication", "sidelink communication", "direct connection", "direct link", "direct communication", "direct link communication" can be interchangeable with each other.

[0269] In some embodiments, the terms "downlink control information (DCI)", "downlink (DL) assignment", "DL DCI", "uplink (UL) grant", "UL DCI" and the like may be used interchangeably.

[0270] In some embodiments, "obtain", "get", "get", "receive", "transmit", "bidirectional transmission", "send and / or receive" can be interchangeable, and can be interpreted as receiving from other entities, obtaining from protocols, obtaining from higher layers, obtaining by self-processing, autonomous implementation, etc.

[0271] In some embodiments, terms such as “trigger,” “generate,” “produce,” “enable,” and “occur” may be used interchangeably.

[0272] Step 2102: The terminal sends the first information.

[0273] Optionally, in some embodiments, the network device receives the first information.

[0274] Optionally, in some embodiments, the first information may be used to request uplink resources.

[0275] Optionally, in some embodiments, the name of the first information is not limited, and may be, for example, "SR", "resource request", "resource scheduling request", etc.

[0276] Optionally, in some embodiments, the terminal sends a physical uplink control channel (PUCCH), which carries the first information. Optionally, the network device receives the PUCCH, but is not limited thereto and may also be other uplink information or uplink channels.

[0277] Optionally, in some embodiments, the above-mentioned “the terminal sends the first information” may include:

[0278] At least one first information triggered by at least one first resource is sent.

[0279] In some embodiments, terms such as "send", "transmit", "report", "download", "transmit", "bidirectional transmission", "send and / or receive" can be used interchangeably.

[0280] In some embodiments, terms such as "physical downlink shared channel (PDSCH)", "DL data", "physical downlink control channel (PDCCH)" can be used interchangeably, and terms such as "physical uplink shared channel (PUSCH)", "UL data", and "PUCCH" can be used interchangeably.

[0281] Step 2103: The terminal starts a first timer.

[0282] Optionally, in some embodiments, after the terminal places the first information in a pending state by triggering the first information, the terminal will subsequently send the first information when it is able to send the first information. Optionally, in some embodiments, the "when the first information can be sent" can be understood as, for example: when the first timer is not turned on, the first timer can be a timer associated with the first information. Optionally, in some embodiments, in order to prevent the first information from being sent frequently, a first timer is associated with the first information, and the first timer is turned on after the first information is sent. During the period when the first timer is in the turned-on state, the first information is prohibited from being sent. Optionally, the above-mentioned "first information is associated with a first timer" can include: one first information is respectively associated with one first timer, or multiple first information are simultaneously associated with one first timer. Optionally, when one first information is respectively associated with one first timer, if any first timer is in the turned-on state, all first information are prohibited from being sent.

[0283] The following is an example of step 2102 and step 2103:

[0284] For example, assuming that in step 2101, the terminal first triggers first information #1 for the first resource #1 and then triggers first information #2 for the first resource #2, the terminal may transmit first information #1 and first information 2 in the following manner: the terminal first transmits first information #1 and starts a first timer; while the first timer is active, even if the terminal triggers first information #2 and places first information #2 in a pending state, the first timer is active and therefore prohibits transmission of first information #2. The terminal may then transmit first information #2 only after the first timer expires.

[0285] In some embodiments, terms such as "period", "moment", "time point", "time", and "time position" can be replaced with each other, and terms such as "duration", "period", "time window", "window", and "time" can be replaced with each other.

[0286] Step 2104: The network device configures uplink resources.

[0287] Optionally, in some embodiments, the terminal receives the uplink resource.

[0288] Optionally, in some embodiments, the uplink resource can be used by the terminal to report SL continuous LBT failures. For example, the uplink resource can be used by the terminal to send the second information to the network device. For a detailed introduction to the second information, please refer to the detailed introduction of step 2101 above.

[0289] Optionally, in some embodiments, the network device sends a Radio Resource Control (RRC) signaling, in which uplink resources are configured. Optionally, the terminal receives the RRC signaling, but is not limited thereto.

[0290] Step 2105: The terminal cancels the first information.

[0291] Optionally, the above-mentioned “canceling the first information” may be cancelling the “triggered first information”. Optionally, in some embodiments, cancelling the first information may include at least one of the following:

[0292] No longer sending the first message, for example, for a "triggered and sent first message", the first message is no longer resent, thereby canceling the first message, or for a "triggered but not sent first message", the first message can be no longer sent, thereby canceling the first message;

[0293] The waiting-for-sending state of the first message may be canceled. For example, for a "first message that has been triggered but not yet sent", the waiting-for-sending state of the first message may be canceled to stop sending the first message, thereby canceling the first message.

[0294] Optionally, in some embodiments, the first information may be cancelled when the terminal meets the second condition.

[0295] Optionally, in some embodiments, the second condition may include at least one of the following:

[0296] The second message was sent successfully;

[0297] At least one first resource-triggered SL continuous LBT failure is canceled.

[0298] For the relevant introduction about the second information, the first resource, and the SL continuous LBT failure, please refer to the above step 2101.

[0299] The following describes the reasons why the first information should be cancelled when the second condition is met:

[0300] Optionally, in some embodiments, it can be known from the aforementioned step 2101 that the first information is a request for uplink resources for reporting SL continuous LBT failure reports, and the SL continuous LBT failure report indicates that the first resource triggers SL continuous LBT failure, with the purpose of achieving recovery of the SL continuous LBT failure of the first resource. Optionally, when the terminal meets the above-mentioned second condition, it means that the terminal has successfully sent the second information, or that at least one SL continuous LBT failure triggered by the first resource is canceled. Optionally, when the terminal successfully sends the second information, it means: the terminal has successfully reported the SL continuous LBT failure report, and at this time there is no need to send the first information to request uplink resources for reporting the SL continuous LBT failure report, so that the first information triggered in step 2101 can be canceled. Optionally, when the SL continuous LBT failure triggered by the first resource is canceled, it means that there is no need to report the SL continuous LBT failure report anymore, and there is no need to use the first information request to request the uplink resources for reporting the SL continuous LBT failure report. Therefore, there is no need to send the first information at this time, and the first information triggered in step 2101 can also be canceled.

[0301] Optionally, in some embodiments, the canceling of the first information may include: canceling the first information triggered by the first resource that meets the second condition.

[0302] Optionally, for example, the first information triggered by the first resource indicated in the successfully sent second information may be canceled.

[0303] For example, assuming that in the above step 2101, the terminal triggered the first information #1 for the first resource #1 and triggered the first information #2 for the first resource #2, and the second information sent by the terminal in the above step 2106 indicates that the first resource #1 triggered SL continuous LBT failure and the first resource #2 triggered SL continuous LBT failure, then in this step 2107, the terminal can cancel the first information #1 and cancel the first information #2.

[0304] Optionally, for example, the first information triggered by the first resource corresponding to the cancellation of SL continuous LBT failure can be cancelled.

[0305] For example, assuming that in the above step 2201, the terminal triggered the first information #1 for the first resource #1 and triggered the first information #2 for the first resource #2, and the SL continuous LBT failure triggered by the first resource #1 in the above step 2206 was canceled, then in this step 2207, the terminal can cancel the first information #1 without canceling the first information #2.

[0306] Optionally, in some other embodiments, the canceling of the first information may include: canceling all triggered first information.

[0307] Optionally, for example, when the terminal successfully sends the above-mentioned second information, no matter which first resource is indicated in the second information, the terminal will cancel all the triggered first information.

[0308] For example, assuming that in the above step 2101, the terminal triggered the first information #1 for the first resource #1 and triggered the first information #2 for the first resource #2, and the second information sent by the terminal in the above step 2106 indicates that the first resource #1 failed to trigger SL continuous LBT, then in this step 2107, the terminal can cancel the first information #1 and the first information #2.

[0309] Optionally, for another example, no matter which first resource's SL continuous LBT failure is canceled, the terminal will cancel all triggered first information.

[0310] For example, assuming that in the above step 2201, the terminal triggered the first information #1 for the first resource #1 and triggered the first information #2 for the first resource #2, and the SL continuous LBT failure triggered by the first resource #1 in the above step 2206 was canceled, then in this step 2207, the terminal can cancel the first information #1 and the first information #2.

[0311] Step 2106: The terminal stops the first timer.

[0312] Optionally, in some embodiments, after the terminal cancels the first information, when a first timer associated with the first information is in an on state, the terminal may stop the first timer.

[0314] In some embodiments, the terms "component carrier (CC)", "cell", "frequency carrier", "carrier frequency" and the like can be used interchangeably.

[0316] In some embodiments, terms such as "certain", "preset", "preset", "setting", "indicated", "a certain", "any", and "first" can be interchangeable. "Specific A", "preset A", "preset A", "setting A", "indicated A", "a certain A", "any A", and "first A" can be interpreted as A pre-specified in a protocol, etc., or as A obtained through setting, configuration, or indication, etc., or as specific A, a certain A, any A, or first A, etc., but not limited to this.

[0317] In some embodiments, the determination or judgment can be performed by a value represented by 1 bit (0 or 1), or by a true or false value (Boolean value) represented by true or false, or by comparison of numerical values ​​(for example, comparison with a predetermined value), but is not limited thereto.

[0318] In some embodiments, "not expecting to receive" can be interpreted as not receiving on time domain resources and / or frequency domain resources, or as not performing subsequent processing on the data after receiving it; "not expecting to send" can be interpreted as not sending, or as sending but not expecting the recipient to respond to the content sent.

If an SR is triggered by a BWP's SL continuous LBT failure, and if a MAC PDU is successfully transmitted and contains a MAC CE (specifically, a SL continuous LBT failure MAC CE), which includes an indication of the BWP's SL continuous LBT failure, the SR is canceled and the SR-ProhibitTimer associated with the SR is stopped. For example, the MAC CE may indicate the BWP's continuous LBT failure status via a bitmap, e.g., the bit corresponding to the BWP is 1.

[0461] Example: The granularity of SL continuous LBT failure detection is resource pool. Replace "BWP" in the above examples with "resource pool".

[0462] Example: The granularity of SL continuous LBT failure detection is RB set (resource block set), and the "BWP" in the above examples is replaced by "RB set".

[0463] Optional Example 2: If the SR is triggered due to a continuous LBT failure of the SL of a BWP / resource pool / RB set, and the continuous LBT failure of the SL of this BWP / resource pool / RB set is cancelled, cancel the SR and stop the prohibit timer associated with this SR.

[0464] Example: The granularity of SL continuous LBT failure detection is BWP. If an SR is triggered due to an SL continuous LBT failure of a BWP, and the SL continuous LBT failure of this BWP is cancelled, the SR is cancelled and the prohibition timer associated with the SR is stopped.

[0465] Example: The granularity of SL continuous LBT failure detection is resource pool. If SR is triggered due to SL continuous LBT failure of a resource pool, and the SL continuous LBT failure of this resource pool is canceled, cancel this SR and stop the prohibition timer associated with this SR.

[0466] Example: The granularity of SL continuous LBT failure detection is RB set. If an SR is triggered due to SL continuous LBT failure of an RB set, and the SL continuous LBT failure of this RB set is cancelled, the SR is cancelled and the prohibit timer associated with the SR is stopped.

[0467] Optional Example 3: If SL Continuous LBT Failure is triggered in at least one BWP / resource pool / RB set and is not cancelled, if there are no available resources, a SL Continuous LBT Failure MAC CE is sent and an SR is triggered.

[0468] Example: The SL continuous LBT failure detection granularity is BWP. If SL continuous LBT failure is triggered in at least one BWP and is not cancelled, if there is no available resource to send SL continuous LBT failure MAC CE, SR is triggered.

[0469] Example: The SL continuous LBT failure detection granularity is the resource pool. If the SL continuous LBT failure is triggered in at least one resource pool and is not cancelled, if there is no available resource, the SL continuous LBT failure MAC CE is sent and the SR is triggered.

[0470] Example: The SL continuous LBT failure detection granularity is RB set. If SL continuous LBT failure is triggered in at least one RB set and is not cancelled, if there is no available resource to send SL continuous LBT failure MAC CE, trigger SR

[0471] Example: No available resources specifically means no uplink new transmission resources or there are uplink new transmission resources but the size of the uplink new transmission resources is insufficient to accommodate the SL continuous LBT failure MAC CE and the subheader of the SL continuous LBT failure MAC CE.
