[0074] In order to facilitate understanding of the embodiments of the present application, the following contents are first described.

[0075] Sidelink (SL) transmission refers to data transmission between terminals such as User Equipment (UE) directly on the physical layer. Sidelink can also be called secondary link, side link, side link, etc.

[0076] In the communication system, unlicensed bands can be used as a supplement to licensed bands to help operators expand their services. For unlicensed bands, Listen Before Talk (LBT) can be used to occupy transmission resources. The types of LBT can be divided into Type 1, Type 2A, Type 2B and Type 2C. Among them, Type 1 LBT is a channel listening mechanism based on back-off. When the transmission node detects that the channel is busy, it backs off and continues to listen until it detects that the channel is empty. Type 2C is that the transmission node does not perform LBT, that is, no LBT or immediate transmission. Type 2A LBT and Type 2B LBT are one-shot LBT, that is, the transmission node performs LBT once before transmission, and transmits if the channel is empty, and does not transmit if the channel is busy. The difference between Type2A LBT and Type2B LBT is: Type2A performs LBT within 25μs, which is applicable when the gap between two transmissions is greater than or equal to 25μs when the channel occupancy time (COT) is shared; while Type2B performs LBT within 16μs, which is applicable when the gap between two transmissions is greater than or equal to 16μs when the COT is shared. In addition, the LBT type also includes Type2, and Type2 LBT is applicable to LAA / eLAA / FeLAA, etc. When the COT is shared and the gap between the two transmissions is greater than or equal to 25μs, the eNB and UE can use Type2 LBT. In addition, the types of LBT can also be divided into Type1, Type2 and Type3. Type1 is a channel listening mechanism based on fallback, Type2 is a one-shot LBT, which performs 5μs LBT within 8μs, and Type3 does not perform LBT.

[0077] In combination with the accompanying drawings, the following detailed description is made of some embodiments and their application scenarios for the LBT failure processing, configuration method, apparatus, terminal and network side equipment provided in the embodiments of the present application.

[0078] See also Figure 2 , Figure 2 is a flowchart of a method for processing LBT failure provided in an embodiment of the present application, the method is executed by a terminal, such as Figure 2 As shown, the method comprises the following steps:

[0079] Step 11: The terminal determines that the first transmission resource triggers SL consistent LBT failure;

[0080] Step 12: The terminal performs the first operation.

[0081] Here, the first transmission resource triggering SL consistent LBT failure can be understood as: the first transmission resource has SL consistent LBT failure.

[0082] Optionally, the first operation includes at least one of the following:

[0083] Sending first information from a Medium Access Control (MAC) layer to a Physical (PHY) layer, wherein the first information notifies information of the first transmission resource;

[0084] Reporting second information to the network side device, or not reporting the second information to the network side device; the second information indicates a first transmission resource that triggers the SL consistent LBT failure; for example, the second information may be a Medium Access Control Control Element (MAC CE), etc.;

[0085] An autonomous recovery is performed for the first transmission resource.

[0086] Therefore, it is clear how to perform the related processing of SL consistent LBT failure, thereby improving the transmission efficiency in the SL unlicensed frequency band.

[0087] Optionally, the information of the first transmission resource includes but is not limited to the granularity of the first transmission resource. The granularity of the first transmission resource can be selected from at least one of the following: resource block set (RB set), resource pool (Resource pool), bandwidth part (Bandwidth Part, BWP), carrier (carrier), etc. For example, a carrier may contain only one BWP; a BWP may contain one or more resource pools, and a resource pool may contain one or more RB sets.

[0088] In an embodiment of the present application, when the terminal uses the first transmission resource for SL transmission, the granularity of the first transmission resource may be RB set, Resource pool, BWP or carrier. Taking RB set as an example, when the terminal determines / judges that SL consistent LBT failure is triggered / occurs on RBset, the MAC layer may notify the PHY layer of the information of the RB set; and after receiving the notification, the PHY layer may learn that the channel access success rate of the RB set is not high, so that the RB set may be excluded during resource selection.

[0089] In some embodiments, when the terminal performs LBT for the transmission opportunity of the sidelink synchronization signal block (Synchronization Signal Block, S-SSB) or the physical sidelink feedback channel (Physical Sidelink Feedback Channel, PSFCH), the occurrence of LBT failure will also be counted, that is, it will be used to determine whether the RB set used for S-SSB or PSFCH transmission has SL consistent LBT failure. However, since SL consistent LBT failure may not affect the terminal's use of the RB set that triggers SL consistent LBT failure for S-SSB or PSFCH transmission, when the RB set triggers SL consistent LBT failure, if the subsequent transmission of the terminal does not involve the transmission of the physical sidelink shared channel (Physical Sidelink Shared Channel, PSSCH) or the physical sidelink control channel (PhysicalSidelink Control Channel, PSCCH), the MAC layer may not need to indicate to the PHY layer the RB set information of the occurrence of SLconsistent LBT failure. Based on this, it is possible to consider optimizing when the MAC layer notifies the PHY layer of the RB set information that triggers / occurs SL consistent LBT failure, thereby saving signaling overhead.

[0090] Optionally, sending the first information from the MAC layer to the PHY layer may include at least one of the following:

[0091] When the terminal triggers resource selection or reselection, sending first information from the MAC layer to the PHY layer;

[0092] For each resource selection process or resource reselection process, first information is sent from the MAC layer to the PHY layer.

[0093] In this way, the MAC layer does not send the first information to the PHY layer without affecting subsequent transmission, thereby saving signaling overhead.

[0094] For SL UE in Radio Resource Control (RRC) connected state, when it is determined that RBset triggers / occurs SL consistent LBT failure, SL LBT failure MACCE can be reported to the base station, that is, the RB set that triggers / occurs SL consistent LBT failure is reported. According to whether the UE is in a connected state and the resource allocation mode, SL UE can be divided into three types of UEs: mode-1UE (this is in RRC connected state), CONNECTED mode-2UE, and IDLE / INACTIVE mode-2UE. Among them, the transmission resources of mode-1UE are scheduled by the base station. When it is determined that RB set has SL consistent LBT failure, mode-1UE can only rely on the configuration of the base station to recover the transmission resources. Therefore, when SL consistent LBT failure occurs, mode-1UE can only recover resources by reporting SL LBT failure MAC CE to the base station. However, since IDLE / INACTIVE mode-2UE has not established an RRC connection with the base station, when it determines that RB set triggers / SL consistent LBT failure occurs, it can only rely on itself to determine whether the transmission resources have been restored, such as based on timer timer / measurement / successful transmission and other conditions. Since INACTIVE mode-2UE can recover resources through the base station or by itself, the behavior of reporting SL LBT failure MAC CE can be determined based on the network configuration.

[0095] Optionally, when it is determined that the first transmission resource triggers SL consistent LBT failure, the terminal may report the second information to or not to the network side device based on the configuration. The LBT failure processing method may also include:

[0096] The terminal receives configuration information, where the configuration information includes at least one of the following:

[0097] first configuration information, where the first configuration information indicates whether the terminal reports information indicating the transmission resources for triggering the SL consistent LBT failure to the network side device when the SL consistent LBT failure is triggered;

[0098] Second configuration information, wherein the second configuration information indicates that when the terminal triggers SL consistent LBT failure, according to the first condition, the terminal reports to the network side device information indicating the transmission resources that trigger SL consistent LBT failure; the first condition includes at least one of the following: the number of transmission resources that trigger SL consistent LBT failure is greater than or equal to the first value, the number of transmission resources that trigger SL consistent LBT failure in the second transmission resources is greater than or equal to the second value, and the first ratio is greater than or equal to the third value; the first ratio is the ratio of the transmission resources that trigger SL consistent LBT failure in the third transmission resources to all transmission resources in the third transmission resources;

[0099] The third configuration information indicates whether the terminal is allowed to report information for indicating the transmission resources that trigger the SL consistent LBT failure to the network side device when the SL consistent LBT failure is triggered. Whether the information for indicating the transmission resources that trigger the SL consistent LBT failure is allowed to be reported to the network side device can be understood as: whether the information for indicating the transmission resources that trigger the SL consistent LBT failure can be reported to the network side device.

[0100] Here, the terminal may receive configuration information from the network side device. The first value, the second value and the third value may be configured, pre-agreed or agreed upon by the network side device, and this is not limited.

[0101] Optionally, when the terminal does not receive the configuration information, the terminal does not report the second information to the network side device, that is, does not indicate the first transmission resource that triggers SL consistent LBT failure to the network side device.

[0102] Optionally, when the configuration information includes the first configuration information, the reporting of the second information to the network side device or not reporting the second information to the network side device may include:

[0103] When the first configuration information indicates that the terminal reports information used to indicate the transmission resources that trigger SL consistent LBT failure to the network side device when the SL consistent LBT failure is triggered, the terminal reports the second information to the network side device; or, when the first configuration information indicates that the terminal does not report information used to indicate the transmission resources that trigger SL consistent LBT failure to the network side device when the SL consistent LBT failure is triggered, the terminal does not report the second information to the network side device.

[0104] For example, assuming that the UE receives the first configuration information of the base station, and the first configuration information indicates whether the UE reports to the base station a MAC CE for indicating the transmission resources that trigger SL consistent LBT failure when SL consistent LBT failure is triggered, then when the UE determines / judges that the first transmission resource triggers SL consistent LBT failure, if the first configuration information indicates that the UE reports to the base station a MAC CE for indicating the transmission resources that trigger SL consistent LBT failure when SL consistent LBT failure is triggered, the UE reports the first MAC CE to the base station; or, if the first configuration information indicates that the UE does not report to the base station a MAC CE for indicating the transmission resources that trigger SL consistent LBT failure when SL consistent LBT failure is triggered, the UE does not report the first MAC CE to the base station; the first MAC CE indicates the first transmission resource that triggers SL consistent LBT failure. In addition, if the UE does not receive the first configuration information of the base station, then when it determines / judges that the first transmission resource triggers SL consistent LBT failure, the UE does not report the first MAC CE to the base station.

[0105] Optionally, when the configuration information includes second configuration information, reporting the second information to the network side device or not reporting the second information to the network side device may include:

[0106] When the first transmission resource meets the first condition, the terminal reports the second information to the network side device; or, when the first transmission resource does not meet the first condition, the terminal does not report the second information to the network side device.

[0107] For example, assume that the UE receives second configuration information of the base station, and the second configuration information indicates that when the UE triggers the SL consistent LBT failure, according to the first condition, the UE reports to the base station a MAC CE of the transmission resources for indicating the triggering of the SL consistent LBT failure; the first condition includes at least one of the following:

[0108] -The number of transmission resources that trigger SL consistent LBT failure is greater than N; the granularity of the transmission resources may be RB set, Resource pool, BWP or carrier; N may be configured by the base station or agreed upon by the protocol, etc.;

[0109] -The number of transmission resources triggering SL consistent LBT failure in the second transmission resource is greater than or equal to M; the granularity of the second transmission resource is greater than the granularity of the transmission resource triggering SL consistent LBT failure; for example, the granularity of the second transmission resource is resource pool, and the granularity of the transmission resource triggering SL consistent LBT failure is RB set; the M may be configured by the base station or agreed upon by the protocol, etc.;

[0110] -The ratio of the transmission resources in the third transmission resources that trigger SL consistent LBT failure to all transmission resources in the third transmission resources is greater than or equal to Q%; the granularity of the second transmission resources is greater than the granularity of the transmission resources that trigger SL consistent LBT failure; for example, the granularity of the second transmission resources is resource pool, and the granularity of the transmission resources that trigger SL consistent LBT failure is RB set; the Q may be configured by the base station or agreed upon by protocol, etc.

[0111] Then, when the UE determines / judges that the first transmission resource triggers SL consistent LBT failure, if the first condition is met, the UE reports the first MAC CE to the base station; or, if the first condition is not met, the UE does not report the first MAC CE to the base station; the first MAC CE indicates the first transmission resource that triggers SL consistent LBT failure. In addition, if the UE does not receive the second configuration information of the base station, when it is determined / judges that the first transmission resource triggers SL consistent LBT failure, the UE does not report the first MAC CE to the base station.

[0112] Optionally, when the configuration information includes third configuration information, reporting the second information to the network side device or not reporting the second information to the network side device may include:

[0113] When the third configuration information indicates that the terminal is allowed to report to the network side device the information used to indicate the transmission resources that trigger the SL consistent LBT failure when the SL consistent LBT failure is triggered, the terminal reports the second information to the network side device based on its own implementation, or does not report the second information to the network side device; or, when the third configuration information indicates that the terminal is not allowed to report to the network side device the information used to indicate the transmission resources that trigger the SL consistent LBT failure when the SL consistent LBT failure is triggered, the terminal does not report the second information to the network side device.

[0114] For example, assuming that the UE receives the third configuration information of the base station, and the third configuration information indicates whether the UE is allowed / can report to the base station a MAC CE for indicating the transmission resources that trigger SL consistent LBT failure when SL consistent LBT failure is triggered, then when the UE determines / judges that the first transmission resource triggers SL consistent LBT failure, if the third configuration information indicates that the UE is allowed / can report to the base station a MAC CE for indicating the transmission resources that trigger SL consistent LBT failure when SL consistent LBT failure is triggered, the UE decides whether to report the first MAC CE to the base station based on its own implementation; or, if the third configuration information indicates that the UE is not allowed / cannot report to the base station a MAC CE for indicating the transmission resources that trigger SL consistent LBT failure when SL consistent LBT failure is triggered, the UE does not report the first MAC CE to the base station; the first MAC CE indicates the first transmission resource that triggers SL consistent LBT failure. In addition, if the UE does not receive the third configuration information of the base station, then when it is determined / judges that the first transmission resource triggers SL consistent LBT failure, the UE does not report the first MAC CE to the base station.

[0115] It should be noted that, for the above embodiment, when the UE does not report the first MAC CE to the base station, the UE can perform autonomous resource recovery based on timer / measurement / successful transmission, etc. for the first transmission resource.

[0116] For mode-2UE, when it is determined / judged that a transmission resource has SL consistent LBT failure, mode-2UE can perform autonomous resource recovery based on timer / measurement / successful transmission and other methods, that is, autonomously judge whether the transmission resource that has SL consistent LBT failure has been restored and is available. For example, when the UE determines that a certain transmission resource has SL consistent LBT failure, the first timer can be started. When the first timer times out, the UE determines that the transmission resource has recovered from SL consistent LBT failure. For another example, when the UE determines that a certain transmission resource has SL consistent LBT failure, the transmission resource can be measured and the resource occupancy rate can be calculated. When the resource occupancy rate of the transmission resource is lower than a preset threshold, the UE determines that the transmission resource has recovered from SL consistent LBT failure. For another example, when the UE determines that a certain transmission resource has SL consistent LBT failure, if the UE successfully performs sidelink SL transmission, it can be determined that the transmission resource has recovered from SL consistent LBT failure.

[0117] Optionally, performing autonomous recovery for the first transmission resource may include:

[0118] The terminal starts a first timer; when the first timer is running, if the second condition is met, the first timer is stopped, and it is determined that the first transmission resource has recovered from the SL consistent LBT failure, or the SL consistent LBT failure is canceled for the first transmission resource; wherein the second condition includes at least one of the following: the terminal successfully performs sidelink transmission, the channel occupancy of the first transmission resource is lower than or equal to the fourth value, the resource occupancy of the first transmission resource is lower than or equal to the fifth value, the channel occupancy of the fourth transmission resource including the first transmission resource is lower than or equal to the sixth value, the resource occupancy of the fifth transmission resource including the first transmission resource is lower than or equal to the seventh value, the terminal reports the second information to the network side device, the first transmission resource is reconfigured by RRC, the terminal receives an RRC reconfiguration message, and the terminal receives an updated System Information Block (SIB) message.

[0119] Here, the first transmission resource being reconfigured by RRC can be understood as the terminal receiving an RRC message and releasing the first transmission resource, that is, the transmission resources of the terminal do not include the first transmission resource, and the RRC message is, for example, RRC reconfiguration information and SIB message. The terminal receiving an RRC reconfiguration message can be understood as the terminal receiving the RRC reconfiguration message confirms that the second condition is met. The terminal receiving an updated SIB message can be understood as the terminal receiving an updated SIB message related to the sidelink configuration.

[0120] The first timer may be configured by the network, pre-agreed, or predetermined by a protocol, etc. The fourth value, the fifth value, the sixth value, and the seventh value may be configured by a network-side device such as a base station, or agreed upon by a protocol, etc., and are not limited thereto. If the first timer times out, it may be determined that the first transmission resource has recovered from the SL consistent LBT failure, or the SL consistent LBT failure may be canceled for the first transmission resource.

[0121] In addition to the first timer described above, in this embodiment, a second timer may be introduced to perform autonomous recovery when all transmission resources in a larger granularity of transmission resources trigger SL consistent LBT failure. The second timer may be configured by the network, pre-agreed, or predetermined by a protocol.

[0122] Optionally, the above-mentioned determination that the first transmission resource triggers SL consistent LBT failure includes: determining that all first transmission resources in the sixth transmission resource trigger SL consistent LBT failure. The granularity of the sixth transmission resource is greater than the granularity of the first transmission resource; for example, the granularity of the sixth transmission resource is resource pool, and the granularity of the first transmission resource is RB set.

[0123] The performing autonomous recovery for the first transmission resource may include:

[0124] The terminal starts a second timer and performs a second operation, where the second operation includes any one of the following:

[0125] 1) When the second timer is running, if the third condition is met, stop the second timer, and determine that all the first transmission resources in the sixth transmission resource are recovered from SL consistent LBT failure, or cancel SL consistent LBT failure for all the first transmission resources in the sixth transmission resource; wherein the third condition includes at least one of the following: the terminal successfully performs sidelink SL transmission, the channel occupancy of some or all of the first transmission resources in the sixth transmission resource is lower than or equal to the eighth value, the resource occupancy of some or all of the first transmission resources in the sixth transmission resource is lower than or equal to the ninth value, the channel occupancy of the sixth transmission resource is lower than or equal to the tenth value, the resource occupancy of the sixth transmission resource is lower than or equal to the eleventh value, the terminal reports the second information to the network side device, the first transmission resource or the sixth transmission resource is reconfigured by RRC, the terminal receives an RRC reconfiguration message, and the terminal receives an updated SIB message; for example, the eighth value, the ninth value, the tenth value and the eleventh value can be configured by the base station, pre-agreed or agreed upon by protocol, etc., and this is not limited;

[0126] 2) When the second timer times out, determine that all the first transmission resources in the sixth transmission resource have recovered from SLconsistent LBT failure, or cancel SLconsistent LBT failure for all the first transmission resources in the sixth transmission resource.

[0127] Here, the second timer may be configured by the network, pre-agreed, or predetermined by an agreement, etc. The first transmission resource or the sixth transmission resource being reconfigured by RRC may be understood as the terminal receiving an RRC message and releasing the first transmission resource or the sixth transmission resource, that is, the transmission resources of the terminal do not include the first transmission resource or the sixth transmission resource, and the RRC message may be, for example, RRC reconfiguration information or a SIB message. The terminal receiving an RRC reconfiguration message may be understood as the terminal confirming that the second condition is met upon receipt of the RRC reconfiguration message. The terminal receiving an updated SIB message may be understood as the terminal receiving an updated SIB message related to the sidelink configuration.

[0128] Optionally, performing autonomous recovery for the first transmission resource may include:

[0129] When the fourth condition is met, the terminal determines that the first transmission resource has recovered from SL consistent LBT failure, or cancels SL consistent LBT failure for the first transmission resource; wherein the fourth condition includes at least one of the following: the terminal successfully performs sidelink transmission using any transmission resource in the seventh transmission resource including the first transmission resource, and the terminal successfully performs sidelink transmission using transmission resources in the eighth transmission resource that does not include the first transmission resource. That is, when it is determined that the first transmission resource triggers SL consistent LBT failure, if the terminal successfully performs sidelink transmission, it can be determined that the first transmission resource has recovered from SL consistent LBT failure, or cancels SL consistent LBT failure for the first transmission resource.

[0130] See also Figure 3 , Figure 3 is a flowchart of an information configuration method provided by an embodiment of the present application, the method is executed by a network side device, such as Figure 3 As shown, the method comprises the following steps:

[0131] Step 31: The network side device sends configuration information to the terminal.

[0132] Here, the configuration information may include at least one of the following:

[0133] first configuration information, where the first configuration information indicates whether the terminal reports information indicating the transmission resources for triggering the SL consistent LBT failure to the network side device when the SL consistent LBT failure is triggered;

[0134] Second configuration information, wherein the second configuration information indicates that when the terminal triggers SL consistent LBT failure, according to the first condition, whether to report information indicating the transmission resources that trigger SL consistent LBT failure to the network side device; the first condition includes at least one of the following: the number of transmission resources that trigger SL consistent LBT failure is greater than or equal to the first value, the number of transmission resources that trigger SL consistent LBT failure in the second transmission resources is greater than or equal to the second value, and the first ratio is greater than or equal to the third value; the first ratio is the ratio of the transmission resources that trigger SL consistent LBT failure in the third transmission resources to all transmission resources in the third transmission resources; the first value, the second value and the third value may be configured by the network side device, pre-agreed, or agreed upon by protocol, etc.;

[0135] The third configuration information indicates whether the terminal is allowed to report information indicating the transmission resources for triggering the SL consistent LBT failure to the network side device when the SL consistent LBT failure is triggered.

[0136] In this way, by sending configuration information to the terminal, the terminal can determine whether to report information indicating the transmission resources that trigger SLconsistent LBT failure.

[0137] For example, assuming that the UE receives the first configuration information of the base station, and the first configuration information indicates whether the UE reports to the base station a MAC CE for indicating the transmission resources that trigger SL consistent LBT failure when SL consistent LBT failure is triggered, then when the UE determines / judges that the first transmission resource triggers SL consistent LBT failure, if the first configuration information indicates that the UE reports to the base station a MAC CE for indicating the transmission resources that trigger SL consistent LBT failure when SL consistent LBT failure is triggered, the UE reports the first MAC CE to the base station; or, if the first configuration information indicates that the UE does not report to the base station a MAC CE for indicating the transmission resources that trigger SL consistent LBT failure when SL consistent LBT failure is triggered, the UE does not report the first MAC CE to the base station; the first MAC CE indicates the first transmission resource that triggers SL consistent LBT failure. In addition, if the UE does not receive the first configuration information of the base station, then when it determines / judges that the first transmission resource triggers SL consistent LBT failure, the UE does not report the first MAC CE to the base station.

[0138] For another example, suppose that the UE receives the second configuration information of the base station, and the second configuration information indicates that when the UE triggers SL consistent LBT failure, according to the first condition, it reports to the base station a MAC CE for indicating the transmission resource that triggers SL consistent LBT failure. Then, when the UE determines / judges that the first transmission resource triggers SL consistent LBT failure, if the first condition is met, the UE reports the first MAC CE to the base station; or, if the first condition is not met, the UE does not report the first MAC CE to the base station; the first MAC CE indicates the first transmission resource that triggers SL consistent LBT failure. In addition, if the UE does not receive the second configuration information of the base station, when it is determined / judges that the first transmission resource triggers SL consistent LBT failure, the UE does not report the first MAC CE to the base station.

[0139] For another example, suppose that the UE receives the third configuration information of the base station, and the third configuration information indicates whether the UE is allowed / can report to the base station a MAC CE for indicating the transmission resources that trigger SL consistent LBT failure when SL consistent LBT failure is triggered. Then, when the UE determines / judges that the first transmission resource triggers SL consistent LBT failure, if the third configuration information indicates that the UE is allowed / can report to the base station a MAC CE for indicating the transmission resources that trigger SL consistent LBT failure when SL consistent LBT failure is triggered, the UE decides whether to report the first MAC CE to the base station based on its own implementation; or, if the third configuration information indicates that the UE is not allowed / cannot report to the base station a MAC CE for indicating the transmission resources that trigger SL consistent LBT failure when SL consistent LBT failure is triggered, the UE does not report the first MAC CE to the base station; the first MAC CE indicates the first transmission resource that triggers SL consistent LBT failure. In addition, if the UE does not receive the third configuration information of the base station, when it determines / judges that the first transmission resource triggers SL consistent LBT failure, the UE does not report the first MAC CE to the base station.

[0140] In the related art, in order to reduce the number of times LBT is performed, the UE or the base station can use time domain continuous resources (such as time slot resources) for transmission. For example, when the UE uses two time domain discontinuous time slots for transmission, it needs to perform LBT twice, and when using two time domain continuous time slots for transmission, if the UE successfully performs LBT for the first time slot, the UE does not need to perform LBT for the second time slot, but can continue to transmit in the first time slot. The time domain continuous time slot resources can be called MCSt (Multi-Consecutive Slot transmission) resources.

[0141] For single-slot transmission resources, when LBT fails for single-slot resources, resource reselection can be performed. However, when LBT fails for one or more slots in MCSt resources, it is not clear in the relevant technology whether to perform resource reselection and under what circumstances to perform resource reselection.

[0142] An optional technical solution is: when the UE fails to perform LBT for resources of one or more time slots in the MCSt resources, it does not perform resource reselection for any of the LBT failures. Another optional technical solution is: the UE waits until the resources of all time slots in the MCSt resources fail to perform LBT, and then performs resource reselection for the transmission processes or transmission blocks TB associated with all time slot resources. The defects of these two technical solutions are: if the front time slot resources in the MCSt resources fail to perform LBT, the UE cannot perform resource reselection for the transmission process or TB associated with the time slot resources in time, which will cause additional transmission delays.

[0143] In response to the above-mentioned defects, taking into account the SL COT sharing technology (this means that a UE can share the remaining unused time of the channel preempted by itself using type1LBT with another UE, so that the other UE can use type2 LBT with a higher channel access success rate to try to preempt the channel), this application proposes that in MCSt resources, for an SL grant, if the UE fails in LBT in the current transmission opportunity, but there are still remaining retransmission opportunities in the MCSt resources, the UE does not perform resource reselection for the current transmission opportunity; or if there are still remaining retransmission opportunities in the MCSt resources, the UE does not perform resource re-evaluation / resource preemption for the current transmission opportunity.

[0144] See also Figure 4 , Figure 4 is a flow chart of a resource processing method provided in an embodiment of the present application, the method is executed by a terminal, such as Figure 4 As shown, the method comprises the following steps:

[0145] Step 41: When the fifth condition is met, the terminal performs a third operation.

[0146] In this embodiment, the fifth condition may include at least one of the following:

[0147] The ninth transmission resource is a resource included in the MCSt resource, and the MCSt resource does not include a retransmission opportunity for the transmission associated with the ninth transmission resource;

[0148] The ninth transmission resource is a resource included in the tenth transmission resource, the ninth transmission resource and the tenth transmission resource are resources within the same channel occupation time COT, and the tenth transmission resource does not include a retransmission opportunity for the transmission associated with the ninth transmission resource; here, for the ninth transmission resource and the tenth transmission resource being resources within the same channel occupation time COT, it can be understood that: the ninth transmission resource and the tenth transmission resource are located in the time domain within the maximum transmission duration that can be occupied by the terminal after the access process using the same type 1LBT channel is successful;

[0149] The ninth transmission resource is a resource included in the MCSt resource, and the remaining transmission resources in the MCSt resource do not include a retransmission opportunity for the transmission associated with the ninth transmission resource; here, the remaining transmission resources represent resources for which LBT has not yet been performed;

[0150] The ninth transmission resource is a resource included in the tenth transmission resource, the ninth transmission resource and the tenth transmission resource are resources within the same channel occupancy time COT, and the remaining transmission resources in the tenth transmission resource do not include the retransmission opportunity of the transmission associated with the ninth transmission resource; here, the remaining transmission resources represent resources for which LBT has not yet been performed.

[0151] The third operation may include at least one of the following:

[0152] For LBT failure of the transmission associated with the ninth transmission resource, performing resource reselection;

[0153] not sending third information from the PHY layer to the MAC layer, the third information indicating performing re-evaluation or resource pre-emption for the ninth transmission resource;

[0154] Ignore, at the MAC layer, fourth information sent by the PHY layer, wherein the fourth information indicates to perform re-evaluation or pre-emption for the ninth transmission resource;

[0155] No re-evaluation check or pre-emption check is performed for the ninth transmission resource at the MAC layer.

[0156] It is understandable that if the fifth condition is not met, the terminal does not perform the third operation.

[0157] In this way, it can be ensured that resource reselection is performed in time for resources that fail to perform LBT, thereby reducing transmission delay.
