Description

Information sending method and device Technical Field

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

[0002] To support direct communication between end devices, direct communication (also called sidelink, SL) has been introduced. The interface between end devices is PC-5. Based on the correspondence between the sending and receiving end devices, 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 Sidelink-U (Sidelink-Unlicensed, unlicensed spectrum of the sidelink) scenario. The terminal device also needs to listen before talk (LBT) when sending Sidelink data on the unlicensed spectrum. The continuous LBT mechanism also applies to Sidelink communication on the unlicensed spectrum.

[0048] It should be noted that the technical solutions of the embodiments of the present disclosure can be applied to various communication systems, such as long-term evolution (LTE) systems, fifth-generation (5G) mobile communication systems, 5G new radio (NR) systems, or other future new mobile communication systems.

[0049] The network device 101 in the embodiment of the present disclosure may be an entity on the network side for transmitting or receiving signals. For example, the network device 101 may be an access network device, including 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 network device 101 provided in the embodiment of the present disclosure may be composed of a centralized unit (CU) and a distributed unit (DU), wherein the CU may also be referred to as a control unit.

[0051] 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.

[0052] In addition, in order to facilitate understanding of the embodiments of the present disclosure, the following points are explained.

[0053] First, in the embodiments of the present disclosure, "used to indicate" can include being used for direct indication and being used for indirect indication. When describing that certain information is used to indicate A, it can include that the information carries A, or it can also include that the information directly indicates A or indirectly indicates A, but it does not necessarily mean that the information carries A.

[0054] The information indicated by the information is called the information to be indicated. In the specific implementation process, there are many ways to indicate the information to be indicated. For example, but not limited to, the information to be indicated can be directly indicated, such as the information to be indicated itself or the index of the information to be indicated. The information to be indicated can also be indirectly indicated by indicating other information, where there is an association between the other information and the information to be indicated. It is also possible to indicate only a part of the information to be indicated, while the other parts of the information to be indicated are known or agreed in advance. For example, the indication of specific information can be achieved by using the arrangement order of each piece of information that is pre-agreed (for example, specified by the protocol), thereby reducing the indication overhead to a certain extent.

[0055] The information to be indicated can be sent as a whole or as multiple sub-information messages that are sent separately. The transmission periods and / or timings of these sub-information messages can be the same or different. The specific transmission method is not limited in this disclosure. The transmission periods and / or timings of these sub-information messages can be predefined, for example, according to a protocol.

[0056] Second, the first, second, and various numbers in this disclosure are only used for the convenience of description and are not intended to limit the scope of the embodiments of this disclosure. For example, to distinguish different information, etc.

[0057] Third, the embodiments of the present disclosure list multiple implementation methods to clearly illustrate the technical solutions of the embodiments of the present disclosure. Of course, those skilled in the art will understand that the multiple embodiments provided in the embodiments of the present disclosure can be implemented individually, combined with the methods of other embodiments of the embodiments of the present disclosure, or implemented individually or in combination with some methods in other related technologies; the embodiments of the present disclosure are not limited to this.

[0058] To support direct communication between terminal devices, the sidelink (SL) communication mode is introduced. The interface between terminal devices is PC-5. Based on the correspondence between the transmitting and receiving terminal devices, 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 the second-stage SCI on the physical sidelink shared channel (PSSCH). These SCIs carry the resource location of the transmitted data and the source and destination identifiers. For packets with hybrid automatic repeat request (HARQ) feedback enabled, the receiving terminal sends a hybrid automatic repeat request acknowledgment (HARQ-ACK) to the PSSCH on the physical sidelink feedback channel (PSFCH).

[0059] There are two ways to allocate transmission resources in Sidelink communication: one is dynamic scheduling by the network device (mode 1), and the other is autonomous selection by the terminal device from the resource pool broadcast by the network device (mode 2). Dynamic scheduling is when the network device 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 the resource pool broadcast by the network device or pre-configured. The network device can configure multiple resource pools for the terminal device on a bandwidth part (BWP). The specific allocation method is configured by the network device through radio resource control (RRC) signaling.

[0060] New radio-unlicensed (NR-U) is a project launched by the Third Generation Partnership Project (3GPP) in Release 16 (R16), which provides operators with the necessary technology to fully integrate unlicensed spectrum into fifth generation (5G) network equipment. NR-U supports uplink and downlink operations in unlicensed frequency 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, hundreds of megahertz), 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.

[0061] Consistent LBT failure is a new feature defined in NR-U. The terminal device counts the number of uplink LBT failures on each BWP. The network device configures the maximum number of consecutive LBT failures (lbt-FailureInstanceMaxCount) and the continuous LBT failure detection time (lbt-FailureDetectionTimer) for the terminal device per serving cell through RRC signaling (for example, lbt-FailureRecoveryConfig) to count consecutive LBT failures. The terminal device maintains an LBT counter (LBT_counter) variable for each cell, and the initial value of the variable is 0.

[0062] Among them, for each activated cell configured with lbt-FailureRecoveryConfig, when the terminal device receives the LBT failure indication submitted by the physical layer, it starts or restarts the lbt-FailureDetectionTimer, and the LBT_counter is increased by 1. When the LBT_counter is greater than or equal to the lbt-FailureInstanceMaxCount, the activated BWP on the cell triggers continuous LBT failure. When the lbt-FailureDetectionTimer times out or the higher layer reconfigures the lbt-FailureInstanceMaxCount / lbt-FailureDetectionTimer or all continuous LBT failures on this service cell are canceled, the terminal device resets the LBT_counter to 0. When the terminal device detects continuous LBT failures on the activated BWP of the PCell (primary cell) or PSCell, if there are other BWPs configured with PRACH resources on the cell, the terminal triggers BWP switch, switches to the BWP configured with PRACH resources and initiates the RACH process. If the terminal device detects continuous LBT failures in N BWPs configured with PRACH resources in the primary cell, the terminal device initiates the radio link failure (RLF) recovery process. If continuous LBT failures are detected on the activated BWP of the SCell (secondary cell), the terminal device indicates to the network device the cell identity of the continuous LBT failure through the Media Access Control Control Element (MAC CE). The MAC CE can carry multiple cell identities of the cells where continuous LBT failures are detected. The MAC CE is sent through other serving cells where no continuous LBT failures have occurred.

[0063] In some embodiments, as shown in Figures 2 and 3, the Continuous LBT Failure MAC CE has two formats: Figure 2 shows a one-byte (Oct) format, and Figure 3 shows a four-byte format. One bit indicates whether the cell associated with ServCellIndex i (e.g., C0, C1, etc.) has detected continuous LBT failures. 1 indicates that the cell associated with ServCellIndex i has detected continuous LBT failures, and 0 indicates that the cell associated with ServCellIndex i has not detected continuous LBT failures.

[0064] 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 rate through effective utilization. This scenario can be called Sindlink-U (Sidelink-Unlicensed, unlicensed spectrum of sidelink) scenario. The terminal device also needs to listen before talk (LBT) 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.

[0065] Based on this, an embodiment of the present disclosure proposes an information transmission method, in which a terminal device sends an indication message to a network device, wherein the indication message is used to indicate the continuous listen-before-talk (LBT) failure status of the sidelink (SL) of a physical resource. This can support the terminal device reporting the continuous LBT failure status of the SL of the physical resource.

[0066] The following is a detailed introduction to an information sending method and device provided by the present disclosure with reference to the accompanying drawings.

[0067] Please refer to Figure 4, which is a flow chart of a method for sending information provided by an embodiment of the present disclosure. As shown in Figure 4, the method is executed by a terminal device and may include but is not limited to the following steps:

[0068] S41: Send indication information to the network device, where the indication information is used to indicate a continuous listen-before-talk (LBT) failure state of the side link SL of the physical resource.

[0069] In an embodiment of the present disclosure, the terminal device may send indication information to the network device, wherein the indication information is used to indicate the status of SL continuous LBT failure of the physical resource.

[0070] The physical resource may be at least one of a resource pool, a resource block set, a carrier, and the like.

[0071] Exemplarily, the terminal device may send indication information to the network device, where the indication information is used to indicate a status of SL continuous LBT failure of at least one resource pool.

[0072] Exemplarily, the terminal device may send indication information to the network device, where the indication information is used to indicate a status of SL continuous LBT failure of at least one resource block set.

[0073] Exemplarily, the terminal device may send indication information to the network device, where the indication information is used to indicate a status of SL continuous LBT failure of at least one carrier.

[0074] In some embodiments, the terminal device sends indication information to the network device, including: sending a MAC CE to the network device, wherein the MAC CE includes the indication information.

[0075] In an embodiment of the present disclosure, a terminal device may send a MAC CE to a network device, wherein the MAC CE includes indication information, and the indication information is used to indicate the status of SL continuous LBT failure of at least one physical resource. Thus, the terminal device can be supported to report the status of SL continuous LBT failure of the physical resource.

[0076] In some embodiments, the physical resources include a resource block set, and the indication information is used to indicate a status of SL continuous LBT failure of at least one resource block set.

[0077] In the embodiment of the present disclosure, the physical resources include a resource block set. In this case, the indication information may be used to indicate a SL continuous failure state of at least one resource block set.

[0078] In some embodiments, the indication information includes a first bitmap, the first bitmap includes a first bit; the first bit corresponds to a resource block set; or the first bit corresponds to an index identifier associated with the resource block set, and different resource block sets correspond to different index identifiers.

[0079] In some embodiments, the indication information includes a first bitmap.

[0080] In an embodiment of the present disclosure, the indication information may include a first bitmap, and the first bitmap may be used to indicate a state of SL continuous LBT failure of at least one resource block set.

[0081] In some embodiments, at least one first bit of the first bitmap corresponds one-to-one to at least one resource block set.

[0082] In the embodiment of the present disclosure, at least one first bit of the first bitmap corresponds one-to-one to at least one resource block set, and different values ​​of the first bit can be used to indicate different SL continuous LBT failure states of the corresponding resource block set.

[0083] Exemplarily, when the value of the first bit is "1", it is used to indicate that the corresponding resource block set triggers SL continuous LBT failure and the triggered SL continuous LBT failure status is not canceled; when the value of the first bit is "0", it is used to indicate that the corresponding resource block set does not trigger SL continuous LBT failure, or is used to indicate that the corresponding resource block set triggers SL continuous LBT failure and the triggered SL continuous LBT failure status has been canceled.

[0084] The first bit may directly correspond to the resource block set, or the first bit may also correspond to specific information of the resource block set, and the specific information may uniquely determine the resource block set corresponding to the first bit. Exemplarily, the specific information may be an index identifier of the resource block set.

[0085] In some embodiments, at least one first bit of the first bitmap corresponds one-to-one to an index identifier associated with at least one resource block set, wherein different resource block sets correspond to different index identifiers.

[0086] It is understood that different index identifiers may be assigned to different resource block sets, where different resource block sets may include different resource block sets in different resource pools, as well as different resource block sets in the same resource pool. In other words, each resource block set belonging to an unlicensed carrier has a unique index identifier.

[0087] In some embodiments, resource block sets belonging to unlicensed carriers may be respectively assigned corresponding different index identifiers.

[0088] In an embodiment of the present disclosure, when different resource block sets correspond to different index identifiers, at least one first bit of the first bit map can correspond one-to-one with an index identifier associated with at least one resource block set. Thus, the first bit can be used to indicate the state of SL continuous LBT failure of the resource block set associated with the corresponding index identifier.

[0089] In some embodiments, the first bit is a first value, used to indicate that the state of continuous LBT failure of the resource block set corresponding to the first bit is a first state, and the first state is that SL continuous LBT failure is triggered and the triggered SL continuous LBT failure state is not canceled; or the first bit is a second value, used to indicate that the state of continuous LBT failure of the resource block set corresponding to the first bit is a second state, and the second state is that SL continuous LBT failure is not triggered, or SL continuous LBT failure is triggered, and the triggered SL continuous LBT failure state has been canceled.

[0090] In an embodiment of the present disclosure, when the first bit corresponds to a resource block set, the resource block set corresponding to the first bit may be a resource block set directly corresponding to the first bit; when the first bit corresponds to an index identifier associated with the resource block set, the resource block set corresponding to the first bit may be a resource block set associated with the index identifier corresponding to the first bit.

[0091] It can be understood that the state of SL continuous LBT failure of the resource block set is the first state. At this time, the resource block set triggers SL continuous LBT failure and is not cancelled, and the resource block set cannot be used for SL transmission.

[0092] It can be understood that the state of SL continuous LBT failure of the resource block set is the second state. At this time, the resource block set does not trigger SL continuous LBT failure, or triggers SL continuous LBT failure and has been cancelled, and the resource block set can be used for SL transmission.

[0093] In some embodiments, the first bit is a first value, used to indicate that the resource block set associated with the index identifier corresponding to the first bit triggers SL continuous LBT failure and the triggered SL continuous LBT failure status has not been canceled; the first bit is a second value, used to indicate that the resource block set associated with the index identifier corresponding to the first bit does not trigger SL continuous LBT failure, or is used to indicate that the resource block set associated with the index identifier corresponding to the first bit triggers SL continuous LBT failure and the triggered SL continuous LBT failure status has been canceled.

[0094] In an embodiment of the present disclosure, when the first bit can be used to indicate the state of SL continuous LBT failure of the resource block set associated with the corresponding index identifier, the first bit is a first value, which can be used to indicate that the resource block set associated with the index identifier corresponding to the first bit triggers SL continuous LBT failure and the triggered SL continuous LBT failure state is not canceled.

[0095] In an embodiment of the present disclosure, when the first bit can be used to indicate the state of SL continuous LBT failure of the resource block set associated with the corresponding index identifier, the first bit is a second value, which can be used to indicate that the resource block set associated with the index identifier corresponding to the first bit does not trigger SL continuous LBT failure, or is used to indicate that the resource block set associated with the index identifier corresponding to the first bit triggers SL continuous LBT failure and the triggered SL continuous LBT failure state has been canceled.

[0096] In some embodiments, the first value may be "1" and the second value may be "0".

[0097] In some embodiments, the first value may be "0" and the second value may be "1".

[0098] In some embodiments, the MAC CE includes indication information for indicating a status of SL continuous LBT failure for at least one resource block set. The first bit length / first bit map length of the MAC CE depends on the maximum identifier of the index identifier of the resource block set that triggers the SL continuous LBT failure.

[0099] For example, if the terminal device can be configured with a maximum of 32 resource block sets, two formats are defined. If the index identifier of the resource block set starts from 0, when it is detected that the maximum index identifier of the resource block set that triggers SL continuous LBT failure is less than 8, the first bit length / first bit map length of the MAC CE can be 1 byte, otherwise the first bit length / first bit map length is 4 bytes.

[0100] In some embodiments, the first bit length / first bit map length of the MAC CE depends on the maximum number of resource block sets that can be configured by the terminal device.

[0101] Exemplarily, if the terminal device can be configured with a maximum of less than or equal to 8 resource block sets, the first bit length / first bit map length is 1 byte; if the terminal device can be configured with a maximum of greater than 8 and less than or equal to 16 resource block sets, the first bit length / first bit map length is 2 bytes; if the terminal device can be configured with a maximum of greater than 16 and less than or equal to 24 resource block sets, the first bit length / first bit map length is 3 bytes; if the terminal device can be configured with a maximum of greater than 24 and less than or equal to 32 resource block sets, the first bit length / first bit map length is 4 bytes.

[0102] Exemplarily, as shown in FIG5 , if the terminal device can be configured with a maximum of 16 resource block sets, the first bit length / first bit map length is 2 bytes.

[0103] In some embodiments, the physical resources include resource pools, and the indication information is used to indicate the status of SL continuous LBT failure of at least one resource pool.

[0104] In an embodiment of the present disclosure, the indication information may include a first bitmap, and the first bitmap may be used to indicate a status of SL continuous LBT failure of at least one resource pool.

[0105] In the embodiment of the present disclosure, at least one first bit of the first bitmap corresponds one-to-one to at least one resource pool, and different values ​​of the first bit can be used to indicate different SL continuous LBT failure states of the corresponding resource pool.

[0106] Exemplarily, when the value of the first bit is "1", it is used to indicate that the corresponding resource pool triggers SL continuous LBT failure and the triggered SL continuous LBT failure status has not been canceled; when the value of the first bit is "0", it is used to indicate that the corresponding resource pool does not trigger SL continuous LBT failure, or is used to indicate that the corresponding resource pool triggers SL continuous LBT failure and the triggered SL continuous LBT failure status has been canceled.

[0107] The first bit may directly correspond to the resource pool, or the first bit may also correspond to specific information of the resource pool, and the specific information may uniquely identify the resource pool corresponding to the first bit. Exemplarily, the specific information may be an index identifier of the resource pool.

[0108] In some embodiments, at least one first bit of the first bitmap corresponds to an index identifier associated with at least one resource pool, wherein different resource pools correspond to different index identifiers. In other words, each resource pool belonging to an unlicensed carrier has a unique index identifier.

[0109] It is understandable that different index identifiers may be set for different resource pools.

[0110] In some embodiments, resource pools belonging to unlicensed carriers may be respectively set with corresponding different index identifiers.

[0111] In an embodiment of the present disclosure, when different resource pools correspond to different index identifiers, at least one first bit of the first bit map can correspond one-to-one with an index identifier associated with at least one resource pool. Thus, the first bit can be used to indicate the status of SL continuous LBT failure of the resource pool associated with the corresponding index identifier.

[0112] In some embodiments, the first bit is a first value, used to indicate that the resource pool associated with the index identifier corresponding to the first bit triggers SL continuous LBT failure and the triggered SL continuous LBT failure status has not been canceled; the first bit is a second value, used to indicate that the resource pool associated with the index identifier corresponding to the first bit does not trigger SL continuous LBT failure, or is used to indicate that the resource pool associated with the index identifier corresponding to the first bit triggers SL continuous LBT failure and the triggered SL continuous LBT failure status has been canceled.

[0113] In an embodiment of the present disclosure, when the first bit can be used to indicate the SL continuous LBT failure status of the resource pool associated with the corresponding index identifier, the first bit is a first value, which can be used to indicate that the resource pool associated with the index identifier corresponding to the first bit triggers SL continuous LBT failure and the triggered SL continuous LBT failure status is not canceled.

[0114] In an embodiment of the present disclosure, when the first bit can be used to indicate the SL continuous LBT failure status of the resource pool associated with the corresponding index identifier, the first bit is the second value, which can be used to indicate that the resource pool associated with the index identifier corresponding to the first bit has not triggered the SL continuous LBT failure, or used to indicate that the resource pool associated with the index identifier corresponding to the first bit has triggered the SL continuous LBT failure and the triggered SL continuous LBT failure status has been canceled.

[0115] In some embodiments, the first value may be "1" and the second value may be "0".

[0116] In some embodiments, the first value may be "0" and the second value may be "1".

[0117] In some embodiments, the MAC CE includes indication information for indicating a status of SL continuous LBT failure of at least one resource pool. The first bit length / first bit map length of the MAC CE depends on the maximum identifier of the index identifier of the resource pool that triggers the SL continuous LBT failure.

[0118] For example, if the terminal device can be configured with a maximum of 32 resource pools, two formats are defined. If the index identifier of the resource pool starts from 0, when it is detected that the maximum index identifier of the resource pool that triggers SL continuous LBT failure is less than 8, the first bit length / first bit map length of the MAC CE can be 1 byte, otherwise the first bit length / first bit map length is 4 bytes.

[0119] In some embodiments, the first bit length / first bit map length of the MAC CE depends on the maximum number of resource pools that can be configured by the terminal device.

[0120] Exemplarily, if the terminal device can be configured with a maximum of less than or equal to 8 resource pools, the first bit length / first bit map length is 1 byte; if the maximum number of resource pools that can be configured is greater than 8 and less than or equal to 16, the first bit length / first bit map length is 2 bytes; if the terminal device can be configured with a maximum of greater than 16 and less than or equal to 24 resource pools, the first bit length / first bit map length is 3 bytes; if the maximum number of resource pools that can be configured is greater than 24 and less than or equal to 32, the first bit length / first bit map length is 4 bytes.

[0121] Exemplarily, as shown in FIG6 , if the terminal device can be configured with a maximum of 16 resource pools, the first bit length / first bit map length is 2 bytes.

[0122] In some embodiments, the indication information includes a second bitmap and a resource pool identifier, the second bitmap includes a second bit; the second bit corresponds to a set of resource blocks in a resource pool corresponding to the resource pool identifier; or the second bit corresponds to an index identifier associated with a set of resource blocks in a resource pool corresponding to the resource pool identifier, and different resource block sets in the same resource pool correspond to different index identifiers.

[0123] In some embodiments, the indication information includes a second bitmap and a resource pool identifier.

[0124] In an embodiment of the present disclosure, the indication information may include a second bitmap and a resource pool identifier, and the second bitmap and the resource pool identifier may be used to indicate the status of SL continuous LBT failure of at least one resource block set in the resource pool corresponding to the resource pool identifier.

[0125] In some embodiments, at least one second bit of the second bitmap corresponds one-to-one to at least one resource block set in the resource pool corresponding to the resource pool identifier.

[0126] In an embodiment of the present disclosure, when the indication information includes a second bitmap and a resource pool identifier, at least one second bit of the second bitmap corresponds one-to-one to at least one resource block set in the resource pool corresponding to the resource pool identifier, and the second bit can be used to indicate the status of SL continuous LBT failure of the resource block set corresponding to the resource pool corresponding to the resource pool identifier.

[0127] Exemplarily, when the value of the second bit is "1", it is used to indicate that the resource block set corresponding to the resource pool corresponding to the resource pool identifier triggers SL continuous LBT failure and the triggered SL continuous LBT failure status is not canceled; when the value of the second bit is "0", it is used to indicate that the resource block set corresponding to the resource pool corresponding to the resource pool identifier does not trigger SL continuous LBT failure, or is used to indicate that the resource block set corresponding to the resource pool corresponding to the resource pool identifier triggers SL continuous LBT failure and the triggered SL continuous LBT failure status has been canceled.

[0128] In some embodiments, at least one second bit of the second bitmap corresponds one-to-one with an index identifier associated with at least one resource block set in the resource pool corresponding to the resource pool identifier, where different resource block sets in the same resource pool correspond to different index identifiers. In other words, each resource block set in the same resource pool has a unique identifier.

[0129] It is understandable that different index identifiers may be set for different resource block sets in the same resource pool.

[0130] In an embodiment of the present disclosure, when different resource block sets in the same resource pool correspond to different index identifiers, at least one second bit of the second bitmap corresponds one-to-one to the index identifier associated with at least one resource block set in the resource pool corresponding to the resource pool identifier. Thus, the second bit can be used to indicate the status of SL continuous LBT failure of the resource block set associated with the corresponding index identifier in the resource pool corresponding to the resource pool identifier.

[0131] In some embodiments, the second bit is a first value, used to indicate that in the resource pool, the state of continuous LBT failure of the resource block set corresponding to the second bit is a third state, and the third state is that SL continuous LBT failure is triggered, and the triggered SL continuous LBT failure state has not been canceled; or the second bit is a second value, used to indicate that in the resource pool, the state of continuous LBT failure of the resource block set corresponding to the second bit is a fourth state, and the fourth state is that SL continuous LBT failure is not triggered, or SL continuous LBT failure is triggered, and the triggered SL continuous LBT failure state has been canceled.

[0132] In an embodiment of the present disclosure, when the second bit corresponds to a resource block set in a resource pool corresponding to a resource pool identifier, the resource block set corresponding to the second bit may be a resource block set directly corresponding to the second bit in the resource pool corresponding to the resource pool identifier; when the second bit corresponds to an index identifier associated with a resource block set in a resource pool corresponding to the resource pool identifier, the resource block set corresponding to the second bit may be a resource block set associated with the index identifier corresponding to the second bit.

[0133] It can be understood that the state of SL continuous LBT failure of the resource block set is the third state. At this time, the resource block set triggers SL continuous LBT failure and is not cancelled, and the resource block set cannot be used for SL transmission.

[0134] It can be understood that the state of SL continuous LBT failure of the resource block set is the fourth state. At this time, the resource block set does not trigger SL continuous LBT failure, or triggers SL continuous LBT failure and has been cancelled, and the resource block set can be used for SL transmission.

[0135] In some embodiments, the second bit is a first value, used to indicate that the set of resource blocks associated with the index identifier corresponding to the second bit in the resource pool corresponding to the resource pool identifier triggers SL continuous LBT failure and the triggered SL continuous LBT failure status has not been canceled; the second bit is a second value, used to indicate that the set of resource blocks associated with the index identifier corresponding to the second bit in the resource pool corresponding to the resource pool identifier does not trigger SL continuous LBT failure, or is used to indicate that the set of resource blocks associated with the index identifier corresponding to the second bit in the resource pool corresponding to the resource pool identifier triggers SL continuous LBT failure and the triggered SL continuous LBT failure status has been canceled.

[0136] In an embodiment of the present disclosure, when the second bit can be used to indicate the state of SL continuous LBT failure of the resource block set associated with the index identifier corresponding to the resource pool corresponding to the resource pool identifier, the second bit is a first value, used to indicate that the resource block set associated with the index identifier corresponding to the second bit in the resource pool corresponding to the resource pool identifier triggers SL continuous LBT failure and the triggered SL continuous LBT failure state is not canceled.

[0137] In an embodiment of the present disclosure, when the second bit can be used to indicate the state of SL continuous LBT failure of the resource block set associated with the index identifier corresponding to the resource pool corresponding to the resource pool identifier, the second bit is a second value, used to indicate that the resource block set associated with the index identifier corresponding to the second bit in the resource pool corresponding to the resource pool identifier does not trigger SL continuous LBT failure, or is used to indicate that the resource block set associated with the index identifier corresponding to the second bit in the resource pool corresponding to the resource pool identifier triggers SL continuous LBT failure and the triggered SL continuous LBT failure state has been canceled.

[0138] In some embodiments, the first value may be "1" and the second value may be "0".

[0139] In some embodiments, the first value may be "0" and the second value may be "1".

[0140] In some embodiments, the MAC CE includes indication information, where the indication information is used to indicate a status of SL continuous LBT failure of at least one resource block set in the resource pool corresponding to the resource pool identifier.

[0141] In some embodiments, the second bit length / second bitmap length associated with a resource pool identifier depends on the maximum number of resource block sets that can be configured by the terminal device in a resource pool.

[0142] Exemplarily, if the terminal device can be configured with a maximum of less than or equal to 8 resource block sets in a resource pool, the second bit length / second bitmap length associated with a resource pool is 1 byte; if the terminal device can be configured with a maximum of greater than 8 and less than or equal to 16 resource block sets in a resource pool, the second bit length / second bitmap length associated with a resource pool is 2 bytes; if the terminal device can be configured with a maximum of greater than 16 and less than or equal to 24 resource block sets in a resource pool, the second bit length / second bitmap length associated with a resource pool is 3 bytes; if the terminal device can be configured with a maximum of greater than 24 and less than or equal to 32 resource block sets in a resource pool, the second bit length / second bitmap length associated with a resource pool is 4 bytes.

[0143] For example, as shown in Figure 7, if the terminal device can be configured with a maximum of 8 resource pools and a maximum of 8 resource block sets can be configured in a resource pool, the resource pool identifier is 3 bits, and the second bit length / second bitmap length associated with a resource pool identifier is 8 bits. The extra bit is reserved with R bit to ensure 8-bit alignment.

[0144] Exemplarily, as shown in FIG8 , if the terminal device can be configured with up to 8 resource pools and a resource pool can be configured with up to 5 resource block sets, the resource pool identifier is 3 bits, and the second bit length / second bitmap length associated with a resource pool identifier is 5 bits.

[0145] It should be noted that the above examples are for illustration only and are not intended to limit the embodiments of the present disclosure. The format of the MAC CE may also be in other forms.

[0146] In this embodiment or example, unless there is any contradiction, each step can be independent, arbitrarily combined or exchanged in order, and the optional methods or optional examples can be arbitrarily combined and can be arbitrarily combined with other embodiments or examples.

[0147] By implementing the embodiments of the present disclosure, the terminal device sends indication information to the network device, wherein the indication information is used to indicate the continuous listen-before-talk (LBT) failure status of the sidelink (SL) of the physical resource. This supports the terminal device to report the continuous LBT failure status of the SL of the physical resource.

[0148] Please refer to Figure 9, which is a flow chart of another information sending method provided by an embodiment of the present disclosure. As shown in Figure 9, the method is executed by a network device and may include but is not limited to the following steps:

[0149] S91: Receive indication information sent by the terminal device, where the indication information is used to indicate the status of SL continuous LBT failure of the physical resource.

[0150] In an embodiment of the present disclosure, a network device may receive indication information sent by a terminal device, wherein the indication information is used to indicate a status of SL continuous LBT failure of a physical resource.

[0151] The physical resource may be at least one of a resource pool, a resource block set, a carrier, and the like.

[0152] Exemplarily, the network device may receive indication information sent by the terminal device, where the indication information is used to indicate a status of SL continuous LBT failure of at least one resource pool.

[0153] Exemplarily, the network device may receive indication information sent by the terminal device, where the indication information is used to indicate a status of SL continuous LBT failure of at least one resource block set.

[0154] Exemplarily, the network device may receive indication information sent by the terminal device, where the indication information is used to indicate a status of SL continuous LBT failure of at least one carrier.

[0155] In some embodiments, the network device receives indication information sent by the terminal device, including: receiving a MAC CE sent by the terminal device, wherein the MAC CE includes the indication information.

[0156] In an embodiment of the present disclosure, a network device may receive a MAC CE sent by a terminal device, wherein the MAC CE includes indication information, and the indication information is used to indicate a status of a continuous SL LBT failure of at least one physical resource. Thus, the terminal device may be supported to report the status of a continuous SL LBT failure of the physical resource.

[0157] In some embodiments, the physical resources include a resource block set, and the indication information is used to indicate a status of SL continuous LBT failure of at least one resource block set.

[0158] In the embodiment of the present disclosure, the physical resources include a resource block set. In this case, the indication information may be used to indicate a SL continuous failure state of at least one resource block set.

[0159] In some embodiments, the indication information includes a first bitmap, the first bitmap includes a first bit; the first bit corresponds to a resource block set; or the first bit corresponds to an index identifier associated with the resource block set, and different resource block sets correspond to different index identifiers.

[0160] In some embodiments, the indication information includes a first bitmap.

[0161] In an embodiment of the present disclosure, the indication information may include a first bitmap, and the first bitmap may be used to indicate a state of SL continuous LBT failure of at least one resource block set.

[0162] In some embodiments, at least one first bit of the first bitmap corresponds one-to-one to at least one resource block set.

[0163] In the embodiment of the present disclosure, at least one first bit of the first bitmap corresponds one-to-one to at least one resource block set, and different values ​​of the first bit can be used to indicate different SL continuous LBT failure states of the corresponding resource block set.

[0164] Exemplarily, when the value of the first bit is "1", it is used to indicate that the corresponding resource block set triggers SL continuous LBT failure and the triggered SL continuous LBT failure status is not canceled; when the value of the first bit is "0", it is used to indicate that the corresponding resource block set does not trigger SL continuous LBT failure, or is used to indicate that the corresponding resource block set triggers SL continuous LBT failure and the triggered SL continuous LBT failure status has been canceled.

[0165] The first bit may directly correspond to the resource block set, or the first bit may also correspond to specific information of the resource block set, and the specific information may uniquely determine the resource block set corresponding to the first bit. Exemplarily, the specific information may be an index identifier of the resource block set.

[0166] In some embodiments, at least one first bit of the first bitmap corresponds one-to-one with an index identifier associated with at least one resource block set, where different resource block sets correspond to different index identifiers. In other words, each resource block set belonging to an unlicensed carrier has a unique index identifier.

[0167] It is understandable that different index identifiers may be set for different resource block sets, respectively. Different resource block sets may include different resource block sets in different resource pools and different resource block sets in the same resource pool.

[0168] In some embodiments, resource block sets belonging to unlicensed carriers may be respectively assigned corresponding different index identifiers.

[0169] In an embodiment of the present disclosure, when different resource block sets correspond to different index identifiers, at least one first bit of the first bit map can correspond one-to-one with an index identifier associated with at least one resource block set. Thus, the first bit can be used to indicate the state of SL continuous LBT failure of the resource block set associated with the corresponding index identifier.

[0170] In some embodiments, the first bit is a first value, used to indicate that the state of continuous LBT failure of the resource block set corresponding to the first bit is a first state, and the first state is that SL continuous LBT failure is triggered and the triggered SL continuous LBT failure state is not canceled; or the first bit is a second value, used to indicate that the state of continuous LBT failure of the resource block set corresponding to the first bit is a second state, and the second state is that SL continuous LBT failure is not triggered, or SL continuous LBT failure is triggered, and the triggered SL continuous LBT failure state has been canceled.

[0171] In an embodiment of the present disclosure, when the first bit corresponds to a resource block set, the resource block set corresponding to the first bit may be a resource block set directly corresponding to the first bit; when the first bit corresponds to an index identifier associated with the resource block set, the resource block set corresponding to the first bit may be a resource block set associated with the index identifier corresponding to the first bit.

[0172] It can be understood that the state of SL continuous LBT failure of the resource block set is the first state. At this time, the resource block set triggers SL continuous LBT failure and is not cancelled, and the resource block set cannot be used for SL transmission.

[0173] It can be understood that the state of SL continuous LBT failure of the resource block set is the second state. At this time, the resource block set does not trigger SL continuous LBT failure, or triggers SL continuous LBT failure and has been cancelled, and the resource block set can be used for SL transmission.

[0174] In some embodiments, the first bit is a first value, used to indicate that the resource block set associated with the index identifier corresponding to the first bit triggers SL continuous LBT failure and the triggered SL continuous LBT failure status has not been canceled; the first bit is a second value, used to indicate that the resource block set associated with the index identifier corresponding to the first bit does not trigger SL continuous LBT failure, or is used to indicate that the resource block set associated with the index identifier corresponding to the first bit triggers SL continuous LBT failure and the triggered SL continuous LBT failure status has been canceled.

[0175] In an embodiment of the present disclosure, when the first bit can be used to indicate the state of SL continuous LBT failure of the resource block set associated with the corresponding index identifier, the first bit is a first value, which can be used to indicate that the resource block set associated with the index identifier corresponding to the first bit triggers SL continuous LBT failure and the triggered SL continuous LBT failure state is not canceled.

[0176] In an embodiment of the present disclosure, when the first bit can be used to indicate the state of SL continuous LBT failure of the resource block set associated with the corresponding index identifier, the first bit is a second value, which can be used to indicate that the resource block set associated with the index identifier corresponding to the first bit does not trigger SL continuous LBT failure, or is used to indicate that the resource block set associated with the index identifier corresponding to the first bit triggers SL continuous LBT failure and the triggered SL continuous LBT failure state has been canceled.

[0177] In some embodiments, the first value may be "1" and the second value may be "0".

[0178] In some embodiments, the first value may be "0" and the second value may be "1".

[0179] In some embodiments, the MAC CE includes indication information for indicating a status of SL continuous LBT failure for at least one resource block set. The first bit length / first bit map length of the MAC CE depends on the maximum identifier of the index identifier of the resource block set that triggers the SL continuous LBT failure.

[0180] For example, if the terminal device can be configured with a maximum of 32 resource block sets, two formats are defined. If the index identifier of the resource block set starts from 0, when it is detected that the maximum index identifier of the resource block set that triggers SL continuous LBT failure is less than 8, the first bit length / first bit map length of the MAC CE can be 1 byte, otherwise the first bit length / first bit map length is 4 bytes.

[0181] In some embodiments, the first bit length / first bit map length of the MAC CE depends on the maximum number of resource block sets that can be configured by the terminal device.

[0182] Exemplarily, if the terminal device can be configured with a maximum of less than or equal to 8 resource block sets, the first bit length / first bit map length is 1 byte; if the terminal device can be configured with a maximum of greater than 8 and less than or equal to 16 resource block sets, the first bit length / first bit map length is 2 bytes; if the terminal device can be configured with a maximum of greater than 16 and less than or equal to 24 resource block sets, the first bit length / first bit map length is 3 bytes; if the terminal device can be configured with a maximum of greater than 24 and less than or equal to 32 resource block sets, the first bit length / first bit map length is 4 bytes.

[0183] Exemplarily, as shown in FIG5 , if the terminal device can be configured with a maximum of 16 resource block sets, the first bit length / first bit map length is 2 bytes.

[0184] In some embodiments, the physical resources include resource pools, and the indication information is used to indicate the status of SL continuous LBT failure of at least one resource pool.

[0185] In an embodiment of the present disclosure, the indication information may include a first bitmap, and the first bitmap may be used to indicate a status of SL continuous LBT failure of at least one resource pool.

[0186] In the embodiment of the present disclosure, at least one first bit of the first bitmap corresponds one-to-one to at least one resource pool, and different values ​​of the first bit can be used to indicate different SL continuous LBT failure states of the corresponding resource pool.

[0187] Exemplarily, when the value of the first bit is "1", it is used to indicate that the corresponding resource pool triggers SL continuous LBT failure and the triggered SL continuous LBT failure status has not been canceled; when the value of the first bit is "0", it is used to indicate that the corresponding resource pool does not trigger SL continuous LBT failure, or is used to indicate that the corresponding resource pool triggers SL continuous LBT failure and the triggered SL continuous LBT failure status has been canceled.

[0188] The first bit may directly correspond to the resource pool, or the first bit may also correspond to specific information of the resource pool, and the specific information may uniquely identify the resource pool corresponding to the first bit. Exemplarily, the specific information may be an index identifier of the resource pool.

[0189] In some embodiments, at least one first bit of the first bitmap corresponds to an index identifier associated with at least one resource pool, wherein different resource pools correspond to different index identifiers. In other words, each resource pool belonging to an unlicensed carrier has a unique index identifier.

[0190] It is understandable that different index identifiers may be set for different resource pools.

[0191] In some embodiments, resource pools belonging to unlicensed carriers may be respectively set with corresponding different index identifiers.

[0192] In an embodiment of the present disclosure, when different resource pools correspond to different index identifiers, at least one first bit of the first bit map can correspond one-to-one with an index identifier associated with at least one resource pool. Thus, the first bit can be used to indicate the status of SL continuous LBT failure of the resource pool associated with the corresponding index identifier.

[0193] In some embodiments, the first bit is a first value, used to indicate that the resource pool associated with the index identifier corresponding to the first bit triggers SL continuous LBT failure and the triggered SL continuous LBT failure status has not been canceled; the first bit is a second value, used to indicate that the resource pool associated with the index identifier corresponding to the first bit does not trigger SL continuous LBT failure, or is used to indicate that the resource pool associated with the index identifier corresponding to the first bit triggers SL continuous LBT failure and the triggered SL continuous LBT failure status has been canceled.

[0194] In an embodiment of the present disclosure, when the first bit can be used to indicate the SL continuous LBT failure status of the resource pool associated with the corresponding index identifier, the first bit is a first value, which can be used to indicate that the resource pool associated with the index identifier corresponding to the first bit triggers SL continuous LBT failure and the triggered SL continuous LBT failure status is not canceled.

[0195] In an embodiment of the present disclosure, when the first bit can be used to indicate the SL continuous LBT failure status of the resource pool associated with the corresponding index identifier, the first bit is the second value, which can be used to indicate that the resource pool associated with the index identifier corresponding to the first bit has not triggered the SL continuous LBT failure, or used to indicate that the resource pool associated with the index identifier corresponding to the first bit has triggered the SL continuous LBT failure and the triggered SL continuous LBT failure status has been canceled.

[0196] In some embodiments, the first value may be "1" and the second value may be "0".

[0197] In some embodiments, the first value may be "0" and the second value may be "1".

[0198] In some embodiments, the MAC CE includes indication information for indicating a status of SL continuous LBT failure of at least one resource pool. The first bit length / first bit map length of the MAC CE depends on the maximum identifier of the index identifier of the resource pool that triggers the SL continuous LBT failure.

[0199] For example, if the terminal device can be configured with a maximum of 32 resource pools, two formats are defined. If the index identifier of the resource pool starts from 0, when it is detected that the maximum index identifier of the resource pool that triggers SL continuous LBT failure is less than 8, the first bit length / first bit map length of the MAC CE can be 1 byte, otherwise the first bit length / first bit map length is 4 bytes.

[0200] In some embodiments, the first bit length / first bit map length of the MAC CE depends on the maximum number of resource pools that can be configured by the terminal device.

[0201] Exemplarily, if the terminal device can be configured with a maximum of less than or equal to 8 resource pools, the first bit length / first bit map length is 1 byte; if the maximum number of resource pools that can be configured is greater than 8 and less than or equal to 16, the first bit length / first bit map length is 2 bytes; if the terminal device can be configured with a maximum of greater than 16 and less than or equal to 24 resource pools, the first bit length / first bit map length is 3 bytes; if the maximum number of resource pools that can be configured is greater than 24 and less than or equal to 32, the first bit length / first bit map length is 4 bytes.

[0202] Exemplarily, as shown in FIG6 , if the terminal device can be configured with a maximum of 16 resource pools, the first bit length / first bit map length is 2 bytes.

[0203] In some embodiments, the indication information includes a second bitmap and a resource pool identifier, the second bitmap includes a second bit; the second bit corresponds to a set of resource blocks in a resource pool corresponding to the resource pool identifier; or the second bit corresponds to an index identifier associated with a set of resource blocks in a resource pool corresponding to the resource pool identifier, and different resource block sets in the same resource pool correspond to different index identifiers.

[0204] In some embodiments, the indication information includes a second bitmap and a resource pool identifier.

[0205] In an embodiment of the present disclosure, the indication information may include a second bitmap and a resource pool identifier, and the second bitmap and the resource pool identifier may be used to indicate the status of SL continuous LBT failure of at least one resource block set in the resource pool corresponding to the resource pool identifier.

[0206] In some embodiments, at least one second bit of the second bitmap corresponds one-to-one to at least one resource block set in the resource pool corresponding to the resource pool identifier.

[0207] In an embodiment of the present disclosure, when the indication information includes a second bitmap and a resource pool identifier, at least one second bit of the second bitmap corresponds one-to-one to at least one resource block set in the resource pool corresponding to the resource pool identifier, and the second bit can be used to indicate the status of SL continuous LBT failure of the resource block set corresponding to the resource pool corresponding to the resource pool identifier.

[0208] Exemplarily, when the value of the second bit is "1", it is used to indicate that the resource block set corresponding to the resource pool corresponding to the resource pool identifier triggers SL continuous LBT failure and the triggered SL continuous LBT failure status is not canceled; when the value of the second bit is "0", it is used to indicate that the resource block set corresponding to the resource pool corresponding to the resource pool identifier does not trigger SL continuous LBT failure, or is used to indicate that the resource block set corresponding to the resource pool corresponding to the resource pool identifier triggers SL continuous LBT failure and the triggered SL continuous LBT failure status has been canceled.

[0209] In some embodiments, at least one second bit of the second bitmap corresponds one-to-one with an index identifier associated with at least one resource block set in the resource pool corresponding to the resource pool identifier, where different resource block sets in the same resource pool correspond to different index identifiers. In other words, each resource block set in the same resource pool has a unique identifier.

[0210] It is understandable that different index identifiers may be set for different resource block sets in the same resource pool.

[0211] In an embodiment of the present disclosure, when different resource block sets in the same resource pool correspond to different index identifiers, at least one second bit of the second bitmap corresponds one-to-one to the index identifier associated with at least one resource block set in the resource pool corresponding to the resource pool identifier. Thus, the second bit can be used to indicate the status of SL continuous LBT failure of the resource block set associated with the corresponding index identifier in the resource pool corresponding to the resource pool identifier.

[0212] In some embodiments, the second bit is a first value, used to indicate that in the resource pool, the state of continuous LBT failure of the resource block set corresponding to the second bit is a third state, and the third state is that SL continuous LBT failure is triggered, and the triggered SL continuous LBT failure state has not been canceled; or the second bit is a second value, used to indicate that in the resource pool, the state of continuous LBT failure of the resource block set corresponding to the second bit is a fourth state, and the fourth state is that SL continuous LBT failure is not triggered, or SL continuous LBT failure is triggered, and the triggered SL continuous LBT failure state has been canceled.

[0213] In an embodiment of the present disclosure, when the second bit corresponds to a resource block set in a resource pool corresponding to a resource pool identifier, the resource block set corresponding to the second bit may be a resource block set directly corresponding to the second bit in the resource pool corresponding to the resource pool identifier; when the second bit corresponds to an index identifier associated with a resource block set in a resource pool corresponding to the resource pool identifier, the resource block set corresponding to the second bit may be a resource block set associated with the index identifier corresponding to the second bit.

[0214] It can be understood that the state of SL continuous LBT failure of the resource block set is the third state. At this time, the resource block set triggers SL continuous LBT failure and is not cancelled, and the resource block set cannot be used for SL transmission.

[0215] It can be understood that the state of SL continuous LBT failure of the resource block set is the fourth state. At this time, the resource block set does not trigger SL continuous LBT failure, or triggers SL continuous LBT failure and has been cancelled, and the resource block set can be used for SL transmission.

[0216] In some embodiments, the second bit is a first value, used to indicate that the set of resource blocks associated with the index identifier corresponding to the second bit in the resource pool corresponding to the resource pool identifier triggers SL continuous LBT failure and the triggered SL continuous LBT failure status has not been canceled; the second bit is a second value, used to indicate that the set of resource blocks associated with the index identifier corresponding to the second bit in the resource pool corresponding to the resource pool identifier does not trigger SL continuous LBT failure, or is used to indicate that the set of resource blocks associated with the index identifier corresponding to the second bit in the resource pool corresponding to the resource pool identifier triggers SL continuous LBT failure and the triggered SL continuous LBT failure status has been canceled.

[0217] In an embodiment of the present disclosure, when the second bit can be used to indicate the state of SL continuous LBT failure of the resource block set associated with the index identifier corresponding to the resource pool corresponding to the resource pool identifier, the second bit is a first value, used to indicate that the resource block set associated with the index identifier corresponding to the second bit in the resource pool corresponding to the resource pool identifier triggers SL continuous LBT failure and the triggered SL continuous LBT failure state is not canceled.

[0218] In an embodiment of the present disclosure, when the second bit can be used to indicate the state of SL continuous LBT failure of the resource block set associated with the index identifier corresponding to the resource pool corresponding to the resource pool identifier, the second bit is a second value, used to indicate that the resource block set associated with the index identifier corresponding to the second bit in the resource pool corresponding to the resource pool identifier does not trigger SL continuous LBT failure, or is used to indicate that the resource block set associated with the index identifier corresponding to the second bit in the resource pool corresponding to the resource pool identifier triggers SL continuous LBT failure and the triggered SL continuous LBT failure state has been canceled.

[0219] In some embodiments, the first value may be "1" and the second value may be "0".

[0220] In some embodiments, the first value may be "0" and the second value may be "1".

[0221] In some embodiments, the MAC CE includes indication information, where the indication information is used to indicate a status of SL continuous LBT failure of at least one resource block set in the resource pool corresponding to the resource pool identifier.

[0222] In some embodiments, the second bit length / second bitmap length associated with a resource pool identifier depends on the maximum number of resource block sets that can be configured by the terminal device in a resource pool.

[0223] Exemplarily, if the terminal device can be configured with a maximum of less than or equal to 8 resource block sets in a resource pool, the second bit length / second bitmap length associated with a resource pool is 1 byte; if the terminal device can be configured with a maximum of greater than 8 and less than or equal to 16 resource block sets in a resource pool, the second bit length / second bitmap length associated with a resource pool is 2 bytes; if the terminal device can be configured with a maximum of greater than 16 and less than or equal to 24 resource block sets in a resource pool, the second bit length / second bitmap length associated with a resource pool is 3 bytes; if the terminal device can be configured with a maximum of greater than 24 and less than or equal to 32 resource block sets in a resource pool, the second bit length / second bitmap length associated with a resource pool is 4 bytes.

[0224] For example, as shown in Figure 7, if the terminal device can be configured with a maximum of 8 resource pools and a maximum of 8 resource block sets can be configured in a resource pool, the resource pool identifier is 3 bits, and the second bit length / second bitmap length associated with a resource pool identifier is 8 bits. The extra bit is reserved with R bit to ensure 8-bit alignment.

[0225] Exemplarily, as shown in FIG8 , if the terminal device can be configured with a maximum of 8 resource pools and a resource pool can be configured with a maximum of 5 resource block sets, the resource pool identifier is 3 bits, and the second bit length / second bitmap length associated with a resource pool identifier is 5 bits.

[0226] It should be noted that the above examples are for illustration only and are not intended to limit the embodiments of the present disclosure. The format of the MAC CE may also be in other forms.

[0227] In this embodiment or example, unless there is any contradiction, each step can be independent, arbitrarily combined or exchanged in order, and the optional methods or optional examples can be arbitrarily combined and can be arbitrarily combined with other embodiments or examples.

[0228] By implementing the embodiment of the present disclosure, the network device receives the indication information sent by the terminal device, wherein the indication information is used to indicate the SL continuous LBT failure status of the physical resource, thereby supporting the terminal device to report the SL continuous LBT failure status of the physical resource.

[0229] To facilitate understanding of the embodiments of the present disclosure, the following exemplary embodiments are provided.

[0230] In an exemplary embodiment, the status of consecutive LBT failures of the SL of a certain RB set / resource pool is directly indicated through a bitmap.

[0231] In some embodiments, the continuous LBT failure detection granularity is RB set, and the RB set belonging to the unlicensed carrier has a unique index.

[0232] In some embodiments, different RB sets have different indices.

[0233] In some embodiments, RSi indicates whether the RB set associated with RSi triggers SL continuous LBT failure, 1 indicates that the RB set associated with RSi triggers SL continuous LBT failure, and 0 indicates that the RB set associated with RSi does not trigger continuous LBT failure. Specifically, the RB set associated with RSi can be the RB set with RB set index i.

[0234] In some embodiments, the bit length / bitmap length of the MAC CE depends on the maximum identifier of the RB set in which consecutive LBT failures are detected.

[0235] In some embodiments, if a maximum of 32 RB sets are supported, two formats are defined. If the maximum identifier of the RB set in which continuous LBT occurs is less than 8, the bit length / bitmap length is 1 byte, otherwise the bit length / bitmap length is 4 bytes.

[0236] In some embodiments, the bit length / bitmap length of the MAC CE depends on the maximum number of RB sets supported. If a maximum of 8 RB sets are supported, the bit length / bitmap length is 1 byte; if a maximum of 16 RB sets are supported, the bit length / bitmap length is 2 bytes (as shown in Figure 5); if a maximum of 32 RB sets are supported, the bit length / bitmap length is 4 bytes. There is no specific limit on the maximum number of RB sets supported.

[0237] In some embodiments, the continuous LBT failure detection granularity is a resource pool, and the resource pool belonging to the unlicensed carrier has a unique index.

[0238] In some embodiments, Ri indicates whether the resource pool associated with Ri triggers SL continuous LBT failure, 1 means that the resource pool associated with Ri triggers SL continuous LBT failure, and 0 means that the resource pool associated with Ri does not trigger continuous LBT failure. Specifically, the resource pool associated with Ri can be the resource pool with Resource pool index i.

[0239] In some embodiments, the bit length / bitmap length of the MAC CE depends on the maximum identifier of the resource pool where continuous LBT failures are detected. If the maximum identifier of the resource pool where continuous LBT failures are detected is less than 8, the bit length / bitmap length is 1 byte.

[0240] In some embodiments, the bit length / bitmap length of the MAC CE depends on the number of resource pools. If a maximum of 8 resource pools are supported, the bit length / bitmap length is 1 byte; if a maximum of 16 resource pools are supported, the bit length / bitmap length is 2 bytes (as shown in Figure 6); if a maximum of 32 resource pools are supported, the bit length / bitmap length is 4 bytes. There is no specific limit on the maximum number of resource pools supported.

[0241] In some embodiments, the status of SL continuous LBT failure of a certain RB set is indicated by a bitmap and a resource pool identifier.

[0242] In some embodiments, the granularity for continuous LBT failure detection is the RB set. RB sets in different resource pools belonging to unlicensed carriers have unique indices within their respective resource pools. This means that different RB sets in the same resource pool have different indices, but different RB sets in different resource pools may have the same index. The status of continuous LBT failure for a particular RB set is indicated by a resource pool identifier and a bitmap.

[0243] In some embodiments, RSi is used to indicate whether the RB set associated with RSi on the resource pool associated with resource pool index triggers SL continuous LBT failure. 1 indicates that the RB set associated with RSi triggers SL continuous LBT failure, and 0 indicates that the RB set associated with RSi does not trigger continuous LBT failure.

[0244] In some embodiments, the size of i depends on the maximum number of RB sets in a resource pool and is not limited. The resource pool identifier depends on the maximum number of resource pools on a carrier and is not limited. For example, if a resource pool supports a maximum of 8 RB sets, the resource pool identifier is 3 bits. If a resource pool supports a maximum of 8 RB sets, the bit length / bitmap length is 8 bits. The excess bits are reserved as Rbits to ensure 8-bit alignment (as shown in Figure 7).

[0245] For example, if a resource pool supports a maximum of 8 resources, the resource pool identifier is 3 bits. If a resource pool supports a maximum of 5 RB sets, the bit length / bitmap length is 5 bits (as shown in Figure 8). Other implementation methods may exist and are not specifically limited.
