Description

Information sending method, information receiving method and device thereof Technical Field

[0001] The present disclosure relates to the field of communication technology, and in particular to an information sending method, an information receiving method and a device thereof. Background Art

[0002] To support direct communication between terminals, direct communication (also called sidelink, SL) was introduced. The interface between terminals is PC-5. Depending on the correspondence between the sending and receiving terminals, three transmission modes are supported on the sidelink: unicast, multicast, and broadcast.

[0003] For version R18 Sidelink, it supports working in unlicensed spectrum. Sidelink communication can use unlicensed frequency band spectrum for communication. The unlicensed frequency band spectrum is open and can improve performance and speed through effective utilization. This scenario can be called Sindlink-U (Sidelink-Unlicensed, unlicensed spectrum of sidelink) scenario. The terminal device also needs to perform LBT (listen before talk) when sending Sidelink data on the unlicensed spectrum. The continuous LBT mechanism also applies to Sidelink communication on the unlicensed spectrum.

[0004] However, there is currently a lack of effective means to report consecutive LBT failures in SL.

[0047] The embodiments of the present disclosure are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present disclosure, and are not to be construed as limitations on the present disclosure. In the description of the present disclosure, unless otherwise specified, " / " means or, for example, A / B means A or B; "and / or" in this article is merely a description of the association relationship of associated objects, indicating that there are three relationships, for example, A and / or B means: A exists alone, A and B exist at the same time, and B exists alone.

[0048] It should be noted that the method provided in any embodiment of the present disclosure may be executed alone, or in combination with possible implementation methods in other embodiments, or in combination with any technical solution in related technologies.

[0049] To facilitate understanding, the terms involved in this disclosure are first introduced.

[0050] 1. LBT (listen before talk)

[0051] In NR-U (new-radio in unlicensed spectrum), when a terminal device accesses an uplink or downlink channel, it must first perform LBT. This means the terminal device must first sense the communication channel to determine whether it is busy. If the channel is detected to be busy, LBT fails and needs to wait for a period of time before performing LBT again.

[0052] 2. Consistent LBT failure

[0053] If the terminal device detects that the channel is busy when performing LBT, it determines that the LBT has failed, and the terminal device counts the number of LBT failures on the physical resources used for SL communication. The network device configures the maximum number of consecutive LBT failures and the consecutive LBT failure detection timer for the terminal device. In the NR-U system, the terminal device maintains an LBT_counter (counter) variable for each cell, and the initial value of the variable is 0. For each activated cell and configured as above, when the terminal device receives the LBT failure indication submitted by the physical layer, the LBT_counter is increased by 1. When the LBT_counter is greater than or equal to the maximum number of consecutive LBT failures, the consecutive LBT failure is determined. When the consecutive LBT failure detection timer times out, the terminal device resets the LBT_counter to 0 and restarts the counting.

[0054] It should be noted that to support direct communication between terminals, a direct link (also called sidelink, SL) communication mode is introduced, and the interface between terminals is PC-5. Based on the correspondence between the transmitting and receiving terminals, three transmission modes are supported on the sidelink: unicast, multicast, and broadcast. The transmitting terminal sends sidelink control information (SCI) on the physical sidelink control channel (PSCCH) and second-stage SCI on the physical sidelink shared channel (PSSCH). These SCIs carry the resource location of the transmitted data as well as the source and destination identifiers. For packets with HARQ (Hybrid Automatic Repeat reQuest) feedback enabled, the receiving terminal provides HARQ-ACK (Hybrid Automatic Retransmission Request Acknowledgement) feedback on the physical sidelink feedback channel (PSFCH).

[0055] There are two ways to allocate transmission resources in Sidelink communication: one is dynamic scheduling by the network (mode 1), and the other is autonomous selection by the terminal device from a network-configured or pre-configured resource pool (mode 2). Dynamic scheduling is when the network dynamically allocates transmission resources on the Sidelink to the terminal device based on the cached data reported by the terminal device, while autonomous selection is when the terminal device randomly selects transmission resources from a network-configured or pre-configured resource pool. The network can configure multiple resource pools for a terminal device on a single BWP (Bandwidth Part). The specific allocation method used is configured by the network side through RRC (Radio Resource Control) signaling.

[0056] NR-U (also known as 5G NR-U, 5G New Radio in Unlicensed Spectrum, License free band 5G NR, 5G air interface operating in unlicensed bands) is a project established by 3GPP (3rd Generation Partnership Project) in version R16, which provides operators with the necessary technologies to fully integrate unlicensed spectrum into 5G networks. NR-U supports uplink and downlink operations in unlicensed bands. In NR-U, channel access for both downlink and uplink relies on the listen before talk (LBT) feature. The wireless device or base station must first "sense" the communication channel and detect that there is no communication before any transmission. When a communication channel is an unlicensed wideband carrier (for example, several hundred MHz), the LBT process relies on detecting energy levels on multiple sub-bands of the communication channel. LBT parameters (such as type / duration, clear channel assessment parameters, etc.) are configured on the wireless device by the base station.

[0057] For version R18 Sidelink, it supports working in unlicensed spectrum. Sidelink communication can use unlicensed frequency band spectrum for communication. The unlicensed frequency band spectrum is open and can improve performance and speed through effective utilization. This scenario can be called Sindlink-U (Sidelink-Unlicensed, unlicensed spectrum of sidelink) scenario. The terminal device also needs to perform LBT (listen before talk) when sending Sidelink data on the unlicensed spectrum. The continuous LBT mechanism is also applicable to Sidelink communication on the unlicensed spectrum. However, there is currently a lack of effective means for reporting SL continuous LBT failures.

[0058] To this end, the embodiments of the present disclosure provide an information sending method, an information receiving method, and apparatus thereof, which can report indication information to the network side to indicate the SL continuous LBT failure status of at least one resource block set or at least one resource pool, so that the network side can perform corresponding processing, thereby improving the communication efficiency of the terminal device performing SL communication, thereby ensuring communication. To better understand the information sending method, information receiving method, and apparatus thereof disclosed in the embodiments of the present disclosure, the following first describes a communication system to which the embodiments of the present disclosure are applicable.

[0059] Please refer to Figure 1, which 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, one network device and one terminal device.

For example, the network 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. The embodiment of the present disclosure does not limit the specific technology and specific device form adopted by the network device.

[0062] The terminal device 102 in the embodiment of the present disclosure is an entity on the user side for receiving or transmitting signals, such as a mobile phone. The terminal device can also be called a terminal device (terminal), user equipment (UE), mobile station (MS), mobile terminal device (MT), etc. The terminal device can be a car with communication function, a smart car, a mobile phone, a wearable device, a tablet computer (Pad), a computer with wireless transceiver function, a virtual reality (VR) terminal device, an augmented reality (AR) terminal device, a wireless terminal device in industrial control (industrial control), a wireless terminal device in self-driving (self-driving), a wireless terminal device in remote medical surgery, a wireless terminal device in smart grid (smart grid), a wireless terminal device in transportation safety (transportation safety), a wireless terminal device in smart city (smart city), a wireless terminal device in smart home (smart home), etc. The embodiment of the present disclosure does not limit the specific technology and specific device form adopted by the terminal device.

[0063] It can be understood that the communication system described in the embodiment of the present disclosure is for the purpose of more clearly illustrating the technical solution of the embodiment of the present disclosure, and does not constitute a limitation on the technical solution provided by the embodiment of the present disclosure. Ordinary technicians in this field can know that with the evolution of the system architecture and the emergence of new business scenarios, the technical solution provided by the embodiment of the present disclosure is also applicable to similar technical problems.

[0064] The information sending method, information receiving method and apparatus thereof provided by the present disclosure are described in detail below with reference to the accompanying drawings.

[0065] Please refer to Figure 2, which is a flowchart illustrating a method for sending information provided by an embodiment of the present disclosure. It should be noted that this method can be applied to a sidelink unlicensed frequency band (Sindlink-U) scenario and can be executed by a terminal device. As shown in Figure 2, this method may include, but is not limited to, the following steps.

[0066] In step 201, instruction information is sent to a network device.

[0067] In the embodiment of the present disclosure, the indication information is used to indicate whether the terminal device detects SL continuous LBT failure on the physical resource. In other words, it indicates whether SL continuous LBT failure is triggered on the physical resource, that is, it indicates whether the state of SL continuous LBT failure is triggered on the physical resource.

[0068] In an embodiment of the present disclosure, a terminal device can count the number of sidelink LBT failures on a physical resource. Optionally, the granularity for detecting consecutive LBT failures in a Sindlink-U scenario can be resource pool granularity or resource block set (RB set) granularity. In one implementation, the physical resource can include any of the following: a resource block set or a resource pool.

[0069] As an example of a possible implementation, the physical resource is a resource block set. Optionally, the terminal device can count the number of side LBT failures on the resource block set. The network side configures the maximum number of SL consecutive LBT failures (such as sl-Lbt-FailureInstanceMaxCount) and the SL consecutive LBT failure detection timer (such as sl-Lbt-FailureDetectionTimer) for each resource block set / resource pool / BWP to the terminal device through RRC (Radio Resource Control) signaling (such as sl-Lbt-FailureRecoveryConfig), wherein the maximum number of consecutive LBT failures and the consecutive LBT failure detection timer are used to count consecutive LBT failures. The terminal device maintains an LBT_counter (LBT counter) variable for each resource block set, and the initial value of the variable is 0. When the terminal device receives an LBT failure indication submitted by the physical layer, it starts or restarts the continuous LBT failure detection timer, and the LBT counter variable is increased by 1. When the LBT counter variable is greater than or equal to the maximum number of consecutive LBT failures, the resource block set triggers an SL consecutive LBT failure. When the SL continuous LBT failure detection timer times out or the higher layer reconfigures the maximum number of SL continuous LBT failures and / or the SL continuous LBT failure detection timer, the terminal device resets the LBT counter variable to 0. When the terminal device determines that at least one resource block set triggers SL continuous LBT failure, the terminal device in the RRC connected state can send SL continuous LBT failure indication information to the network device. The indication information can indicate the SL continuous LBT failure status of the at least one resource block set.

[0070] As an example of another possible implementation, the physical resource is a resource pool. Optionally, the terminal device can count the number of lateral LBT failures on the resource pool. The network side configures the maximum number of SL consecutive LBT failures (such as sl-Lbt-FailureInstanceMaxCount) and the SL consecutive LBT failure detection timer (such as sl-Lbt-FailureDetectionTimer) for each resource pool / BWP to the terminal device through RRC (Radio Resource Control) signaling (such as sl-Lbt-FailureRecoveryConfig), wherein the maximum number of consecutive LBT failures and the consecutive LBT failure detection timer are used to count consecutive LBT failures. The terminal device maintains an LBT_counter (LBT counter) variable for each resource pool, and the initial value of the variable is 0. When the terminal device receives an LBT failure indication submitted by the physical layer, it starts or restarts the consecutive LBT failure detection timer, and the LBT counter variable is increased by 1. When the LBT counter variable is greater than or equal to the maximum number of consecutive LBT failures, the resource pool triggers an SL consecutive LBT failure. When the SL continuous LBT failure detection timer times out or the higher layer reconfigures the maximum number of SL continuous LBT failures and / or the SL continuous LBT failure detection timer, the terminal device resets the LBT counter variable to 0. When the terminal device determines that at least one resource pool triggers SL continuous LBT failure, the terminal device in the RRC connected state can send SL continuous LBT failure indication information to the network device, and the indication information can indicate the SL continuous LBT failure status of at least one resource pool.

[0071] In one implementation, a terminal device may send indication information of SL continuous LBT failure to a network device via a MAC (Media Access Control) CE (Control Element). As an example, the indication information may be MAC CE information, or, as another example, the indication information is carried in the MAC CE information, for example, the MAC CE information includes the indication information, so that the terminal device may send the indication information to the network device via the MAC CE information to indicate to the network device the SL continuous LBT failure status of at least one resource block set or at least one resource pool.

[0072] In some embodiments of the present disclosure, the terminal device is configured to use carrier aggregation, and the physical resources on any one of the aggregated carriers have a unique index identifier. Among them, in an embodiment of the present disclosure, the terminal device can directly indicate the SL continuous LBT failure status of the RB set (resource block set) or resource pool through a bitmap. In one implementation, the terminal device sends an indication message to the network device, and the SL continuous LBT failure indication message includes a first bitmap, and at least one first bit of the first bitmap corresponds to a physical resource associated with at least one index identifier on the carrier, and the bit value of the first bit is used to indicate whether the terminal device triggers SL continuous LBT failure on the physical resource corresponding to the first bit. Optionally, the bit value of the first bit is a first value, used to indicate that an SL continuous LBT failure has been triggered on the physical resource associated with the index identifier corresponding to the first bit and the status of the triggered SL continuous LBT failure has not been canceled; the bit value of the first bit is a second value, used to indicate that an SL continuous LBT failure has not been triggered on the physical resource associated with the index identifier corresponding to the first bit, or used to indicate that an SL continuous LBT failure has been triggered on the physical resource associated with the index identifier corresponding to the first bit and the status of the triggered SL continuous LBT failure has been canceled.

[0073] As an example of a possible implementation, the detection granularity of the SL continuous LBT failure is a resource block set, and the RB set belonging to any carrier has a unique index identifier (index). Exemplarily, if carrier aggregation is not enabled, only one carrier is supported, and different RB sets belonging to this carrier have different indexes. Exemplarily, if carrier aggregation is enabled, multiple carriers are supported, and different RB sets belonging to different / the same carrier have different indexes. That is, the indexes of all RB sets on multiple carriers are different from each other. The SL continuous LBT failure status of the RB set associated with at least one index identifier can be directly indicated by the first bit map. As an example, the bit value of the first bit in the first bit map can be 1, which is used to indicate that the SL continuous LBT failure is triggered on the resource block set associated with the index identifier corresponding to the first bit and the triggered SL continuous LBT failure status is not cancelled; the bit value of the first bit is 0, which is used to indicate that the SL continuous LBT failure is not triggered on the resource block set associated with the index identifier corresponding to the first bit, or is used to indicate that the SL continuous LBT failure is triggered on the resource block set associated with the index identifier corresponding to the first bit and the triggered SL continuous LBT failure status is cancelled. Alternatively, as another example, the bit value of the first bit in the first bitmap may be 0, indicating that a SL continuous LBT failure has been triggered on the resource block set associated with the index identifier corresponding to the first bit and the status of the triggered SL continuous LBT failure has not been canceled; the bit value of the first bit may be 1, indicating that a SL continuous LBT failure has not been triggered on the resource block set associated with the index identifier corresponding to the first bit, or indicating that a SL continuous LBT failure has been triggered on the resource block set associated with the index identifier corresponding to the first bit and the status of the triggered SL continuous LBT failure has been canceled. Alternatively, the bit value of the first bit in the first bitmap may also be other numerical values, which are not limited in this disclosure and will not be elaborated on. Optionally, in this example, the granularity of the resource block set may be greater than the granularity of the resource pool, for example, the resource block set may include one or more resources; or the granularity of the resource pool may be greater than the granularity of the resource block set, for example, the resource pool may include one or more resource block sets.

[0074] For example, as shown in Figure 3, it is an example of the MAC CE format. i The associated RB set can be the RB set with RB set index i, RS i Indicates index identifier RS i Whether SL continuous LBT failure is triggered on the associated RB set. 1 means that SL continuous LBT failure is triggered on the RB set associated with RSi and the triggered SL continuous LBT failure status is not canceled. 0 means RSi No SL continuous LBT failure is triggered on the associated RB set, or 0 indicates that SL continuous LBT failure is triggered on the RB set associated with RSi and the status of the triggered SL continuous LBT failure is canceled. Exemplarily, the size of the indication bit of the first bit map in the indication information depends on the maximum identifier of the RB set where the SL continuous LBT failure is detected. Exemplarily, if a maximum of 32 RB sets can be configured on all carriers, two formats are defined. If the index identifier of the resource block set starts from 0, if the maximum identifier of the RB set where the SL continuous LBT is detected is less than 8, the indication bit is 1 byte, and if the maximum identifier of the RB set where the SL continuous LBT is detected is greater than or equal to 8, the indication bit is 4 bytes. Exemplarily, the size of the indication bit of the first bitmap in the indication information depends on the maximum number of aggregated carriers and / or the maximum number of RB sets that can be configured on one carrier. Exemplarily, if a maximum of 8 RB sets can be configured on all carriers (for example, a maximum of 4 RB sets can be configured on one carrier, and a maximum of 2 carrier aggregation is supported), the indication bit is 1 byte; if a maximum of 16 RB sets can be configured, the indication bit is 2 bytes; if a maximum of 32 RB sets can be configured, the indication bit is 4 bytes. The specific maximum number of RB sets that can be configured is not specifically limited. The specific maximum number of carriers that can be aggregated is not specifically limited. The specific maximum number of RB sets that can be configured on one carrier is not specifically limited.

[0075] It is understandable that each element in the table shown in Figure 3 above exists independently, and these elements are exemplarily listed in the same table, but it does not mean that all elements in the table must exist at the same time as shown in the table. The value of each element is independent of the value of any other element in the table. Therefore, those skilled in the art will understand that the value of each element in the table is an independent embodiment. It should be noted that the present disclosure includes multiple tables, and each of the tables is similar to the table shown in Figure 3, which is to merge multiple independent embodiments into the same table, and each element in these tables should also be considered to be an independent embodiment.

[0076] As an example of another possible implementation, the detection granularity of the SL continuous LBT failure is the resource pool, and the resource pool belonging to any carrier has a unique index identifier (index). Exemplarily, if carrier aggregation is not enabled, only one carrier is supported, and different resource pools belonging to this carrier have different indexes. Exemplarily, if carrier aggregation is enabled, multiple carriers are supported, and different resource pools belonging to different / the same carrier have different indexes. That is, the indexes of all resource pools on multiple carriers are different from each other. The SL continuous LBT failure status of the resource pool associated with at least one index identifier can be directly indicated by the first bit map. As an example, the bit value of the first bit in the first bit map can be 1, which is used to indicate that the SL continuous LBT failure is triggered on the resource pool associated with the index identifier corresponding to the first bit and the triggered SL continuous LBT failure status is not cancelled; the bit value of the first bit is 0, which is used to indicate that the SL continuous LBT failure is not triggered on the resource pool associated with the index identifier corresponding to the first bit, or to indicate that the SL continuous LBT failure is triggered on the resource pool associated with the index identifier corresponding to the first bit and the triggered SL continuous LBT failure status is cancelled. Alternatively, as another example, the bit value of the first bit in the first bitmap may be 0, indicating that a SL continuous LBT failure has been triggered on the resource pool associated with the index identifier corresponding to the first bit and the status of the triggered SL continuous LBT failure has not been canceled; the bit value of the first bit may be 1, indicating that a SL continuous LBT failure has not been triggered on the resource pool associated with the index identifier corresponding to the first bit, or indicating that a SL continuous LBT failure has been triggered on the resource pool associated with the index identifier corresponding to the first bit and the status of the triggered SL continuous LBT failure has been canceled. Alternatively, the bit value of the first bit in the first bitmap may also be other numerical values, which are not limited in this disclosure and will not be elaborated on. Optionally, in this example, the granularity of the resource block set may be greater than the granularity of the resource pool, for example, the resource block set may include one or more resources; or the granularity of the resource pool may be greater than the granularity of the resource block set, for example, the resource pool may include one or more resource block sets.

[0077] For example, as shown in FIG4, it is an example of the MAC CE format. i The associated resource pool can be the resource pool with index i, R i Indicator index R i Whether SL continuous LBT failure is triggered on the associated resource pool. 1 means SL continuous LBT failure is triggered on the resource pool associated with Ri and the triggered SL continuous LBT failure status is not canceled. 0 means R iNo SL continuous LBT failure is triggered on the associated resource pool, or 0 indicates that SL continuous LBT failure is triggered on the resource pool associated with Ri and the status of the triggered SL continuous LBT failure is canceled. Exemplarily, the size of the indication bit of the first bit map in the indication information depends on the maximum identifier of the resource pool where the SL continuous LBT failure is detected. Exemplarily, if a maximum of 32 resource pools can be configured on all carriers, two formats are defined. If the index identifier of the resource pool starts from 0, if the maximum identifier of the resource pool where the SL continuous LBT is detected is less than 8, the indication bit is 1 byte; if the maximum identifier of the resource pool where the SL continuous LBT is detected is greater than or equal to 8, the indication bit is 4 bytes. Exemplarily, the size of the indication bit of the first bitmap in the indication information depends on the maximum number of aggregated carriers and / or the maximum number of resource pools that can be configured on a carrier. Exemplarily, if a maximum of 8 resource pools can be configured on all carriers (for example, a maximum of 4 resource pools can be configured on a carrier, and a maximum of 2 carrier aggregation is supported), the indication bit is 1 byte; if a maximum of 16 resource pools can be configured, the indication bit is 2 bytes; if a maximum of 32 resource pools can be configured, the indication bit is 4 bytes. The specific maximum number of resource pools that can be configured is not specifically limited. The specific maximum number of carriers that can be aggregated is not specifically limited. The specific maximum number of resource pools that can be configured on a carrier is not specifically limited.

[0078] In some embodiments of the present disclosure, the physical resource may be the resource block set, and the terminal device is configured to use carrier aggregation, and any resource block set on the same carrier among the aggregated carriers has a unique index identifier. In an embodiment of the present disclosure, the terminal device may indicate the SL continuous LBT failure state of the resource block set through a bitmap and a carrier identifier. In one implementation, the physical resource is a resource block set; the terminal device sends indication information to the network device, and the indication information includes a second bitmap and a carrier identifier, at least one second bit of the second bitmap corresponds to a resource block set associated with at least one index identifier on a carrier associated with the carrier identifier, and the bit value of the second bit is used to indicate whether the terminal device triggers SL continuous LBT failure with the resource block set corresponding to the second bit, that is, the bit value of the second bit is used to indicate whether the resource block set associated with the index identifier corresponding to the carrier associated with the carrier identifier triggers the SL continuous LBT failure. Optionally, the bit value of the second bit is a first value, used to indicate that the terminal device has triggered SL continuous LBT failure on the resource block set corresponding to the second bit and the status of the triggered SL continuous LBT failure has not been cancelled; the bit value of the second bit is a second value, used to indicate that the terminal device has not triggered SL continuous LBT failure on the resource block set corresponding to the second bit, or used to indicate that the terminal device has triggered SL continuous LBT failure on the resource block set corresponding to the second bit and the status of the triggered SL continuous LBT failure has been cancelled. As an example, the bit value of the second bit is 1, used to indicate that the terminal device has triggered SL continuous LBT failure on the resource block set corresponding to the second bit and the status of the triggered SL continuous LBT failure has not been cancelled; the bit value of the second bit is 0, used to indicate that the terminal device has not triggered SL continuous LBT failure on the resource block set corresponding to the second bit; or the bit value of the second bit is 0, used to indicate that the terminal device has triggered SL continuous LBT failure on the resource block set corresponding to the second bit and the status of the triggered SL continuous LBT failure has been cancelled.

[0079] Optionally, in this example, the granularity of the resource block set may be greater than the granularity of the resource pool, for example, the resource block set may include one or more resources; or the granularity of the resource pool may be greater than the granularity of the resource block set, for example, the resource pool may include one or more resource block sets.

[0080] As an example of a possible implementation, the detection granularity of the SL continuous LBT failure is a resource block set (RB set). If all RB sets on a carrier have a unique index, the SL continuous LBT failure status of the resource block set can be indicated by the carrier identifier and the second bitmap. For example, as shown in Figure 5, it is an example diagram of the MAC CE format. For example, if a maximum of 32 carriers can be configured for aggregation, the carrier identifier can be 5 bits (bit), and the remaining 3 bits R are reserved bits, RS i Used to indicate the carrier RS ​​associated with the carrier identifier (Serving cell index) i Whether SL continuous LBT failure is triggered on the associated RB set. For example, 1 indicates that the RS on the carrier associated with the carrier identifier i SL continuous LBT failure is triggered on the associated RB set and the triggered SL continuous LBT failure status is not cancelled; 0 indicates that the RS on the carrier associated with the carrier identifier i No continuous LBT failure is triggered on the associated RB set, or 0 indicates that the carrier identifier is associated with the RS on the carrier i SL continuous LBT failure is triggered on the associated RB set and the triggered SL continuous LBT failure status is canceled. i The size of i depends on the maximum number of RB sets that can be configured for a carrier, which is not limited in this disclosure. The size of the carrier identifier (Serving cell index) depends on the maximum number of aggregated carriers that can be configured, which is not limited in this disclosure. Other implementation methods may exist and are not specifically limited. It should be noted that the above examples are for illustrative purposes only and do not constitute specific limitations on the embodiments of this disclosure. The format of the MAC CE may also be in other forms.

[0081] In some embodiments of the present disclosure, the physical resource is the resource block set, and the terminal device is configured to use carrier aggregation, and the resource block set on the same carrier and the same resource pool among the aggregated carriers has a unique index identifier in the resource pool to which it belongs. In an embodiment of the present disclosure, the terminal device can indicate the SL continuous LBT failure state of the resource block set by a bitmap, a carrier identifier and a resource pool identifier. In one implementation, the physical resource is a resource block set; the terminal device sends indication information to the network device, and the indication information includes a third bitmap, a carrier identifier and a resource pool identifier, at least one third bit of the third bitmap corresponds to a resource block set associated with at least one index identifier on a first resource pool associated with a resource pool identifier, the first resource pool being a resource pool associated with the resource pool identifier on a carrier associated with the carrier identifier, and the bit value of the third bit is used to indicate whether the terminal device triggers SL continuous LBT failure on the resource block set corresponding to the third bit, that is, the bit value of the third bit is used to indicate whether the resource block set associated with the index identifier corresponding to the resource pool associated with the resource pool identifier on the carrier associated with the carrier identifier triggers SL continuous LBT failure. Optionally, the bit value of the third bit is a first value, used to indicate that the terminal device triggers SL continuous LBT failure on the resource block set corresponding to the third bit and the state of the triggered SL continuous LBT failure has not been cancelled; the bit value of the third bit is a second value, used to indicate that the terminal device does not trigger SL continuous LBT failure on the resource block set corresponding to the third bit, or used to indicate that the terminal device triggers SL continuous LBT failure on the resource block set corresponding to the third bit and the state of the triggered SL continuous LBT failure has been cancelled. As an example, the bit value of the third bit is 1, used to indicate that the terminal device triggers SL continuous LBT failure on the resource block set corresponding to the third bit and the state of the triggered SL continuous LBT failure has not been cancelled; the bit value of the third bit is 0, used to indicate that the terminal device does not trigger SL continuous LBT failure on the resource block set corresponding to the third bit; or the bit value of the third bit is 0, used to indicate that the terminal device triggers SL continuous LBT failure on the resource block set corresponding to the third bit and the state of the triggered SL continuous LBT failure has been cancelled.

[0082] As an example of a possible implementation method, the detection granularity of the SL continuous LBT failure is RB set. If the RB sets on different resource pools on a carrier have unique index identifiers (index) in the resource pools to which they belong, that is, different RB sets on the same resource pool have different indexes, but different RB sets on different resource pools may have the same index. The SL continuous LBT failure status of a certain RB set can be indicated by the carrier identifier, resource pool identifier and the third bitmap. For example, as shown in Figure 6, it is an example diagram of the MAC CE format. For example, if a maximum of 32 carriers are supported for aggregation, the carrier identifier can be 5 bits, and if a maximum of 8 resource pools can be configured on a carrier, the resource pool identifier can be 3 bits. RS i Used to indicate the RS on the resource pool associated with the carrier associated with the serving cell index. i Whether SL continuous LBT failure is triggered on the associated RB set. For example, 1 means the carrier on which the carrier identifier is associated and the resource pool on which the resource pool identifier is associated. i The SL continuous LBT failure is triggered on the associated RB set and the triggered SL continuous LBT failure status is not cancelled; 0 means the carrier on the resource pool associated with the carrier identifier is RS i The associated RB set does not trigger continuous LBT failures, or 0 indicates that the carrier identifier is associated with the carrier, the resource pool identifier is associated with the RS on the resource pool i The associated RB set triggers SL continuous LBT failure and the triggered SL continuous LBT failure status is canceled. The size of i depends on the maximum number of RB sets that can be configured in a resource pool, which is not limited in this disclosure. The size of the carrier identifier depends on the maximum number of aggregated carriers supported, which is not limited in this disclosure. The resource pool identifier depends on the maximum number of resource pools that can be configured in a carrier, which is not limited in this disclosure. For example, if a carrier can be configured with a maximum of 16 resource pools, the resource pool identifier is 4 bits. If a maximum of 8 carrier aggregations are supported, the carrier identifier is 3 bits, and the extra 2 bits are reserved with Rbit to ensure 8-bit alignment. There may be other implementation methods, which are not specifically limited. It should be noted that the above examples are only for illustration and are not specific limitations on the embodiments of the present disclosure. The format of MAC CE can also be in other forms.

[0083] Optionally, in this example, the granularity of the resource pool is greater than the granularity of the resource block set. For example, the resource pool may include one or more resource block sets.

[0084] In some embodiments of the present disclosure, the physical resource is the resource pool, and the terminal device is configured to use carrier aggregation, and any resource pool on the same carrier among the aggregated carriers has a unique index identifier; wherein, in the embodiments of the present disclosure, the terminal device can indicate the SL continuous LBT failure status of the resource pool through the fourth bitmap and the carrier identifier. In one implementation, the physical resource is a resource block resource pool; the terminal device sends indication information to the network device, and the indication information includes a fourth bitmap and a carrier identifier, at least one fourth bit of the fourth bitmap corresponds to a resource pool associated with at least one index identifier on the carrier associated with the carrier identifier, and the bit value of the fourth bit is used to indicate whether the terminal device triggers the SL continuous LBT failure on the resource pool corresponding to the fourth bit. Optionally, the bit value of the fourth bit is a first value, used to indicate that the terminal device has triggered an SL continuous LBT failure on the resource pool corresponding to the fourth bit and the status of the triggered SL continuous LBT failure has not been canceled; the bit value of the fourth bit is a second value, used to indicate that the terminal device has not triggered an SL continuous LBT failure on the resource pool corresponding to the fourth bit, or used to indicate that the terminal device has triggered an SL continuous LBT failure on the resource pool corresponding to the fourth bit and the status of the triggered SL continuous LBT failure has been canceled.

[0085] As an example of a possible implementation, the granularity of the detection of SL continuous LBT failure is the resource pool. If all resource pools on a carrier have a unique index, optionally, resource pools on different carriers may have the same index, then the SL continuous LBT failure status of the resource pool can be indicated by the carrier identifier and the fourth bitmap. For example, as shown in Figure 7, an example diagram of the MAC CE format is shown. For example, if a maximum of 32 carriers are supported, the carrier identifier can be 5 bits, and the remaining 3 bits R are reserved bits, R i Used to indicate the carrier R associated with the carrier identifier (Serving cell index) i Whether SL continuous LBT failure is triggered on the associated resource pool. For example, 1 means R on the carrier associated with the carrier identifier i SL continuous LBT failure is triggered on the associated resource pool and the triggered SL continuous LBT failure status is not cancelled. 0 indicates that the carrier R on the associated carrier is i No continuous LBT failure is triggered on the associated resource pool, or 0 indicates that the carrier identifier is associated with the R i SL continuous LBT failure is triggered on the associated resource pool and the triggered SL continuous LBT failure status is canceled. iThe size of i depends on the maximum number of resource pools that can be configured for a carrier, which is not limited in this disclosure. The size of the carrier identifier (Serving cell index) depends on the maximum number of aggregated carriers supported, which is not limited in this disclosure. Other implementations are possible and are not specifically limited. It should be noted that the above examples are for illustration only and do not constitute specific limitations on the embodiments of this disclosure. The format of the MAC CE can also be in other forms.

[0086] Optionally, in this example, the granularity of the resource pool is greater than the granularity of the resource block set. For example, the resource pool may include one or more resource block sets.

[0087] By implementing the embodiments of the present disclosure, it is possible to report indication information to the network side to inform the network side whether SL continuous LBT failure has been triggered on the physical resource, so that the network side can perform corresponding processing, improve the communication efficiency of the terminal device in SL communication, and thus ensure normal communication. In addition, based on the different detection granularities of SL continuous LBT failures and whether unlicensed spectrum carrier aggregation is enabled, the embodiments of the present disclosure provide a design solution for SL continuous LBT failure MAC CE, thereby resolving the problem of unclear format of continuous LBT failure MAC CE in sidelink communication.
