[0043] For example, the communication system 100 used in the embodiment of the present application is as follows: Figure 1 The communication system 100 may include a network device 110, which may be a device that communicates with a terminal device 120 (or a communication terminal or terminal). The network device 110 may provide communication coverage for a specific geographical area and may communicate with terminal devices located in the coverage area.

Optionally, the communication system 100 may include multiple network devices and each network device may include another number of terminal devices within its coverage area, which is not limited in the embodiments of the present application.

[0045] Optionally, the communication system 100 may also include other network entities such as a network controller and a mobility management entity, which is not limited in the embodiments of the present application.

[0046] It should be understood that the device with communication function in the network / system in the embodiment of the present application can be referred to as a communication device. Figure 1 Taking the communication system 100 shown as an example, the communication equipment may include a network device 110 and a terminal device 120 with communication functions. The network device 110 and the terminal device 120 may be the specific devices described above and will not be repeated here. The communication equipment may also include other devices in the communication system 100, such as a network controller, a mobile management entity and other network entities, which is not limited in the embodiments of the present application.

[0047] It should be understood that the terms "system" and "network" are often used interchangeably in this article. The term "and / or" in this article is only a description of the association relationship of associated objects, indicating that three relationships can exist. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " in this article generally indicates that the associated objects before and after are in an "or" relationship.

[0048] It should be understood that the "indication" mentioned in the embodiments of the present application can be a direct indication, an indirect indication, or an indication of an association relationship. For example, A indicates B, which can mean that A directly indicates B, for example, B can be obtained through A; it can also mean that A indirectly indicates B, for example, A indicates C, and B can be obtained through C; it can also mean that there is an association relationship between A and B.

[0049] In the description of the embodiments of the present application, the term "corresponding" may indicate a direct or indirect correspondence between two items, or an association relationship between the two items, or a relationship between indication and being indicated, configuration and being configured, and the like.

[0050] Unlicensed spectrum is the spectrum allocated by countries and regions that can be used for radio equipment communications. This spectrum is generally considered to be a shared spectrum, that is, as long as communication equipment in different communication systems meets the regulatory requirements set by the country or region on the spectrum, they can use the spectrum without applying for exclusive spectrum authorization from the government.

[0051] In order to allow various communication systems that use unlicensed spectrum for wireless communication to coexist in a friendly manner on the spectrum, some countries or regions have stipulated regulatory requirements that must be met when using unlicensed spectrum. For example, communication equipment follows the "Listen Before Talk (LBT)" principle, that is, before a communication device sends a signal on a channel of the unlicensed spectrum, it needs to first perform channel sensing. Only when the channel sensing result is that the channel is idle can the communication device send a signal; if the channel sensing result of the communication device on the channel of the unlicensed spectrum is that the channel is busy, the communication device cannot send a signal. In order to ensure fairness, in one transmission, the duration of the communication device using the channel of the unlicensed spectrum for signal transmission cannot exceed the maximum channel occupancy time (MCOT).

[0052] In NR-U technology, the Channel Occupancy Time (COT) obtained by the base station can be shared with the uplink transmission of the terminal device. Similarly, the COT obtained by the terminal device can also be shared with the downlink transmission of the base station. When scheduling the uplink transmission of the terminal device, the base station indicates the LBT type and channel access priority in the uplink grant (UL grant) based on the base station's own MCOT, such as whether the time of the scheduled uplink transmission is within the MCOT range of the base station, so that the terminal device can perform LBT before the scheduled uplink transmission.

[0053] In the subsequent technological evolution, the use of unlicensed spectrum in higher frequency bands and related technologies will be considered, such as the 52.6GHz-71GHz discussed in the Release 17 (Rel-17) standard. In high frequency bands, because the beam of signal transmission is narrower and more directional, when performing channel sensing, compared with omnidirectional channel sensing in low frequency bands, a more ideal method is to use directional channel sensing, that is, directional LBT. After channel sensing through directional LBT, if the channel is found to be idle, a signal can be sent through a beam in that direction to occupy the channel. Compared with omnidirectional LBT, directional LBT can increase access opportunities because channel occupation in different beam directions can be performed simultaneously through space division multiplexing. For example Figure 2 As shown in Figure 1, when gNB1 uses omnidirectional LBT, the transmission of gNB2 affects the channel sensing result of gNB1, so that the channel sensing result of gNB1 is non-idle and cannot occupy the channel for UE1 to transmit. Figure 3As shown, when gNB1 adopts directional LBT, it performs channel sensing in the spatial direction of UE1's transmission. At this time, since the transmission from gNB2 to UE2 is also directional, it does not affect the result of gNB1's channel sensing. Therefore, the result of gNB1's channel sensing is idle, and the channel can be occupied for UE1's transmission.

[0054] In addition, in Rel-17, the types of channel sensing that can be used include omnidirectional LBT, directional LBT, and LBT free. Among them, omnidirectional LBT is easy to implement and simplifies system design; directional LBT can improve channel utilization; LBT free also has a simplified design, reduces channel sensing overhead, and has high channel utilization. These types of channel sensing may be used for channel sensing in different scenarios. How to determine which type of channel sensing to use is an urgent problem to be solved.

[0055] Based on the above problems, the present application proposes a channel listening solution, in which the transmitting device can flexibly select the channel listening type from omnidirectional channel listening, directional channel listening, and channel-free channel listening to cope with changes in channel usage and improve channel utilization and transmission efficiency.

[0056] The technical solution of the present application is described in detail below through specific embodiments.

[0057] Figure 4 is a schematic flow chart of a channel monitoring method 200 according to an embodiment of the present application, such as Figure 4 As shown, the method 200 may include at least part of the following contents:

[0058] S210, the transmitting device determines the channel monitoring type;

[0059] S220: The transmitting device occupies the channel according to the channel monitoring type.

[0060] In an embodiment of the present application, the transmitting device can flexibly select the channel listening type from omnidirectional channel listening, directional channel listening, and channel-free channel listening to cope with changes in channel usage and improve channel utilization and transmission efficiency.

[0061] It should be noted that channel sensing can be implemented through LBT or other methods, and this application is not limited to this.

[0062] In an embodiment of the present application, after determining the channel sensing type, the transmitting device may occupy the channel based on the determined channel sensing type.

[0063] For example, when the transmitting device determines to use the omnidirectional channel sensing method to occupy the channel, the transmitting device performs omnidirectional channel sensing. If the sensing result is idle, the channel can be occupied by sending a signal or channel through an omnidirectional beam.

[0064] For another example, when the transmitting device determines to use directional channel sensing to occupy a channel, the transmitting device performs directional channel sensing. If the sensing result is idle, the channel can be occupied by sending a signal or channel through a beam in the channel sensing direction.

[0065] For another example, when the originating device determines to use the channel-free listening mode, the originating device may directly send a signal or a channel to occupy the channel.

[0066] In the embodiment of the present application, the originating device may be a terminal device, or the originating device may be a network device.

[0067] Optionally, in the embodiment of the present application, S210 may specifically be the solutions described in Examples 1 to 6.

[0068] Example 1: The originating device determines to use the second channel listening type for channel listening according to the number of channel listening failures of the first channel listening type. For example, the originating device determines to use the second channel listening type for channel listening according to the number of LBT failures of the first channel listening type.

[0069] It should be noted that in NR-U technology, the transmitting device must first perform channel sensing before occupying the channel. When the first channel sensing type is used for channel sensing, if the channel sensing always fails, it means that the channel sensed by the first channel sensing type is always non-idle. When the channel sensing fails a certain number of times, the transmitting device can change the channel sensing type to continue channel sensing, that is, change from the first channel sensing type to the second channel sensing type, and continue channel sensing.

[0070] Optionally, in Example 1, when the number of channel sensing failures of the first channel sensing type is greater than or equal to a first threshold, the transmitting device determines to use the second channel sensing type for channel sensing.

[0071] Optionally, the first threshold is pre-configured or agreed upon by a protocol, or the first threshold is configured by a network device.

[0072] For example, when the transmitting device performs channel sensing according to omnidirectional channel sensing, if it is always found that the channel is not idle, it means that the transmitting device can at least sense interference from a certain direction. In this case, if the transmitting device fails to perform omnidirectional channel sensing for a certain number of times, it can be converted to directional channel sensing for channel sensing. Since directional channel sensing only senses the state of the channel in a certain direction, the channel in this direction may not be occupied. Then, after the transmitting device performs channel sensing in the manner of directional channel sensing, it may sense that the channel in this direction is idle, thereby performing corresponding transmission. Specifically, the transmitting device determines the direction of channel sensing, and can determine the channel sensing direction according to the spatial information of the transmitted channel or signal. For downlink transmission, that is, the transmitting device is a network device, and the network device can determine the direction of downlink channel sensing according to the spatial information of the downlink channel. For example, the network device can determine the channel sensing direction according to the synchronization signal block (SSB) index associated with the transmitted channel or signal, or the network device determines the channel sensing direction according to the transmission configuration indicator (TCI) state corresponding to the channel. For uplink transmission, that is, the transmitting device is a terminal device, the terminal device can determine the direction of uplink channel monitoring according to the spatial information of the uplink channel.

[0073] It should be noted that one SSB is used to carry the synchronization signal and broadcast channel of one beam. That is, SSB can also be called synchronization signal / physical broadcast channel block (SS / PBCH block).

[0074] Optionally, in Example 1, the transmitting device determines to use the second channel sensing type for channel sensing according to the first timer and the number of channel sensing failures of the first channel sensing type.

[0075] It should be noted that when the channel sensing of the first channel sensing type succeeds, the first timer is reset.

[0076] Optionally, when the channel listening of the first channel listening type continues to fail during the operation of the first timer, or the channel listening of the first channel listening type is not successful during the operation of the first timer, or the number of successful channel listening of the first channel listening type during the operation of the first timer does not reach a second threshold, the transmitting device determines to use the second channel listening type for channel listening when the first timer times out.

[0077] Optionally, the second threshold is pre-configured or agreed upon by a protocol, or the second threshold is configured by a network device.

[0078] It should be noted that the transmitting device determines to use the second channel listening type for channel listening when the first timer times out. This can be understood as the transmitting device determines to use the second channel listening type for channel listening when the first timer times out. It can also be understood as the transmitting device determines to use the second channel listening type for channel listening after the first timer times out.

[0079] For example, Figure 5 As shown, during the operation of the first timer, the transmitting device uses omnidirectional channel sensing to perform channel sensing, but the channel sensing of the omnidirectional channel sensing continues to fail and no channel sensing success occurs during the operation of the first timer. The transmitting device determines to use directional channel sensing to perform channel sensing when the first timer times out, and the channel sensing of the directional channel sensing succeeds.

[0080] Optionally, when the number of channel listening failures of the first channel listening type reaches a third threshold before the first timer times out, the originating device determines to use the second channel listening type for channel listening. That is, when the number of channel listening failures of the first channel listening type reaches the third threshold, the limitation of the first timer can be ignored.

[0081] Optionally, the third threshold is pre-configured or agreed upon by a protocol, or the third threshold is configured by a network device.

[0082] It should be noted that the third threshold value may be the same as or different from the first threshold value.

[0083] Optionally, the first timer is pre-configured or agreed upon by a protocol, or the first timer is configured by a network device.

[0084] In Example 1, for example, the first channel sensing type is omnidirectional channel sensing, and the second channel sensing type is directional channel sensing. For another example, the first channel sensing type is directional channel sensing, and the second channel sensing type is omnidirectional channel sensing.

[0085] Therefore, in the scheme of Example 1, when continuous omnidirectional channel sensing fails, the transmitting device can adjust to a directional channel sensing mode, which can make the channel sensing more targeted and avoid the influence of interference unrelated to the channel direction on the channel sensing results, thereby improving the utilization of the channel.

[0086] Example 2: The originating device determines to use the second channel sensing type for channel sensing according to the number of successful channel sensing of the first channel sensing type. For example, the originating device determines to use the second channel sensing type for channel sensing according to the number of successful LBT of the first channel sensing type.

[0087] It should be noted that in NR-U technology, the transmitting device must first perform channel sensing before occupying the channel. When the first channel sensing type is used for channel sensing, if several channel sensings are successful, it means that the channel sensed by the first channel sensing type is always idle. When the channel sensing is successful a certain number of times, the transmitting device can change the channel sensing type to continue channel sensing, or the transmitting device can switch from the channel sensing state to the channel non-sensing state, that is, the transmitting device can directly occupy the channel.

[0088] Optionally, in Example 2, when the number of successful channel sensing of the first channel sensing type is greater than or equal to a fourth threshold, the transmitting device determines to use the second channel sensing type for channel sensing.

[0089] Optionally, the fourth threshold is pre-configured or agreed upon by a protocol, or the fourth threshold is configured by a network device.

[0090] For example, when the transmitting device performs channel sensing according to omnidirectional channel sensing or directional channel sensing, if it finds that the channel is always idle, it means that the current channel is relatively idle, or the interference is controllable. For example, in a factory, the positions of the transmitting device and the receiving device are fixed, and there are no other interfering transmitting devices within the signal coverage range of the transmitting device. In this case, the transmitting device can occupy the channel in a free channel sensing (LBT free) manner, or the transmitting device can directly use the channel for transmission without channel sensing.

[0091] Optionally, in Example 2, the transmitting device determines to use the second channel sensing type for channel sensing according to the second timer and the number of successful channel sensing of the first channel sensing type.

[0092] It should be noted that, when the channel sensing of the first channel sensing type fails, the second timer is reset.

[0093] Optionally, when the channel listening of the first channel listening type continues to succeed during the operation of the second timer, or the channel listening of the first channel listening type does not fail during the operation of the second timer, or the number of failures of the channel listening of the first channel listening type during the operation of the second timer does not reach a fifth threshold, the transmitting device determines to use the second channel listening type for channel listening when the second timer times out.

[0094] Optionally, the fifth threshold is pre-configured or agreed upon by a protocol, or the fifth threshold is configured by a network device.

[0095] It should be noted that the transmitting device determines to use the second channel listening type for channel listening when the second timer times out. This can be understood as the transmitting device determining to use the second channel listening type for channel listening when the second timer times out. It can also be understood as the transmitting device determining to use the second channel listening type for channel listening after the second timer times out.

[0096] For example, Figure 6 As shown, during the operation of the second timer, the transmitting device uses omnidirectional channel sensing to perform channel sensing, but the channel sensing of the omnidirectional channel sensing continues to be successful and no channel sensing failure occurs during the operation of the second timer. The transmitting device determines to occupy the channel without channel sensing when the second timer times out, that is, directly occupy the channel when the second timer times out.

[0097] Optionally, when the number of successful channel sensing of the first channel sensing type reaches the sixth threshold before the second timer times out, the originating device determines to use the second channel sensing type for channel sensing. That is, when the number of successful channel sensing of the first channel sensing type reaches the sixth threshold, the restriction of the second timer can be ignored.

[0098] Optionally, the sixth threshold is pre-configured or agreed upon by a protocol, or the sixth threshold is configured by a network device.

[0099] It should be noted that the sixth threshold value may be the same as or different from the fourth threshold value.

[0100] Optionally, the second timer is preconfigured or agreed upon by a protocol, or the second timer is configured by a network device.

[0101] In Example 2, for example, the first channel sensing type is directional channel sensing, and the second channel sensing type is omnidirectional channel sensing. For another example, the first channel sensing type is directional channel sensing, and the second channel sensing type is free channel sensing. For another example, the first channel sensing type is omnidirectional channel sensing, and the second channel sensing type is free channel sensing. For another example, the first channel sensing type is omnidirectional channel sensing, and the second channel sensing type is directional channel sensing.

[0102] Optionally, in Example 2, when the transmitting device uses the channel in a channel listening free (LBT free) manner, in order to avoid changes in the channel interference environment, the transmitting device can also periodically perform omnidirectional channel listening or directional channel listening in the channel listening free (LBT free) manner. When the omnidirectional channel listening or directional channel listening is successful, the channel listening free (LBT free) manner is maintained; otherwise, the second timer is started, and the channel listening type is switched again based on whether channel listening successes continue to occur and no channel listening failures occur within a time period within the second timer. When the second timer times out, the channel listening type is switched.

[0103] Therefore, in the solution of Example 2, after continuous omnidirectional channel sensing succeeds, it can be adjusted to directional channel sensing, or channel sensing can be omitted (channel sensing-free), or channel sensing can be performed periodically. When the channel load is relatively small, the channel sensing overhead is reduced, thereby improving the channel utilization. At the same time, periodic channel sensing can avoid possible interference to other devices and ensure fairness in channel use.

[0104] It should be noted that the above-mentioned Example 1 and Example 2 can be superimposed as follows: the transmitting device determines to use the second channel listening type for channel listening according to the channel listening result of the first channel listening type. That is, the channel listening result of the first channel listening type can be the number of channel listening failures of the first channel listening type in Example 1, and the channel listening result of the first channel listening type can also be the number of channel listening successes of the first channel listening type in Example 2. In this case, the transmitting device can flexibly change the type of channel listening according to the channel listening result of the first channel listening type, so that the channel listening type of the device better matches the current channel usage, thereby improving the channel occupancy efficiency.

[0105] Example 3: The transmitting device determines the channel sensing type according to the measurement result.

[0106] Optionally, the measurement result is used to reflect the occupancy status of the channel, or the measurement result is used to reflect the channel quality.

[0107] Optionally, in Example 3, the measurement result includes but is not limited to at least one of the following:

[0108] The measurement results of the received signal strength indication (RSSI), the channel occupancy (Channel occupancy), the channel state information reference signal (CSI-RS), and the sounding reference signal (SRS).

[0109] It should be noted that the measurement result for the CSI-RS may be, for example, a channel quality indicator (Channel Quantity Indicator, CQI).

[0110] For example, when the measurement result reflects that the current channel load is light, the transmitting device determines to use the LBT free mode to occupy the channel. For another example, when the measurement result reflects that the current channel load is heavy, the transmitting device determines to use the omnidirectional channel sensing or directional channel sensing mode to sense the channel.

[0111] Optionally, in Example 3, the originating device may determine the channel listening type according to the measurement result and at least one threshold value. For example, the originating device may determine the load weight of the current channel based on one or more threshold values ​​corresponding to the measurement result. In addition, the current channel may be a channel that the originating device is ready to occupy.

[0112] It should be noted that when the originating device is a terminal device, the originating device can obtain the measurement result through measurement; when the originating device is a network device, the originating device can obtain the measurement result by receiving a measurement report reported by the terminal device.

[0113] Therefore, in the solution of Example 3, the transmitting device can adjust the channel listening type accordingly according to the channel usage reflected by the measurement result, thereby improving the utilization rate of the channel.

[0114] Example 4: The transmitting device determines the channel sensing type according to the reception quality of the channel or signal.

[0115] Optionally, the reception quality includes but is not limited to at least one of the following:

[0116] Signal-to-noise ratio, block error rate (BLER), and hybrid automatic repeat request Acknowledgement (HARQ-ACK) feedback of the physical downlink shared channel (PDSCH).

[0117] For example, when the reception quality reflects that the reception quality of the current channel is good, the transmitting device may determine to use the LBT free mode to occupy the channel. For another example, when the reception quality reflects that the reception quality of the current channel is poor, the transmitting device determines to use the omnidirectional channel sensing or directional channel sensing mode to sense the channel.

[0118] In Example 4, the transmitting device may determine the reception quality of the current channel based on one or more threshold values ​​corresponding to the reception quality. In addition, the current channel may be a channel that the transmitting device is preparing to occupy.

[0119] It should be noted that in Example 4, the originating device may be a terminal device or a network device.

[0120] Therefore, in the solution of Example 4, the transmitting device can adjust the channel listening type accordingly according to the channel reception quality, thereby improving the utilization rate of the channel.

[0121] Example 5: The originating device determines the channel monitoring type according to the indication information.

[0122] Optionally, the indication information is carried in at least one of the following information:

[0123] Downlink Control Information (DCI) used for uplink grant, DCI used to indicate channel occupancy time (COT) information, the second message in four-step random access, uplink control information carried in uplink configuration grant, system information, and paging information.

[0124] For example, Figure 7 As shown, in the COT sharing scenario, the network device carries the indication information in the DCI used for uplink authorization, and the indication information is used for the channel sensing type (LBT). After receiving the DCI, the terminal device determines the channel sensing type based on the indication information, performs channel sensing according to the channel sensing type, and transmits the physical uplink shared channel (Physical Uplink Shared Channel, PUSCH) when the channel sensing result is idle.

[0125] For example, Figure 8 As shown, in the COT sharing scenario, the DCI (such as DCI format 2_0) used to indicate the COT information carries the indication information, and the indication information is used to indicate the channel listening type (LBT) during the COT duration.

[0126] It should be noted that in the NR-U system, DCI format 2_0 can be used for COT-related indication information, including the following indication fields: available LBT bandwidth, COT duration and monitoring group identifier. The COT indication information carried by DCI format2_0 is used to indicate to the UE the channel occupancy obtained by the base station, including the time domain and the frequency domain. In the unlicensed spectrum in the high frequency band, when the base station group common (group common) Physical Downlink Control Channel (PDCCH) instructs the base station to obtain COT information, the channel listening type (LBT) corresponding to the COT can be indicated. The UE that receives the COT indication information carried by the DCI format2_0 can obtain the channel listening type corresponding to the COT. For example, this indication information can be used for the LBT type of the UE when the COT of the base station is shared with the UE.

[0127] For example, Fig. 9 As shown, in the four-step random access process, the terminal device sends the first message (message 1, Msg 1) in the four-step random access. After receiving Msg 1, the network device sends the corresponding message Msg 2, and carries the time-frequency resources for the terminal device to send the third message (message 3, Msg 3) in the four-step random access in Msg 2, and carries the indication information in Msg 2, which is used to indicate the channel listening type (LBT) before sending Msg 3.

[0128] For example, Fig.10 As shown, in the COT sharing scenario, the terminal device includes the indication information in the uplink control information (UCI) carried in the uplink configuration grant (UplinkConfigure Grant, CG-UL), and the indication information is used to indicate the channel listening type (LBT) before the downlink transmission starts. After receiving the indication information, the network device determines the channel listening type (LBT) before the downlink transmission starts according to the indication information.

[0129] Therefore, in the solution of Example 5, the network device or the terminal device can flexibly indicate the channel listening type through the indication information, thereby improving the utilization rate of the channel.

[0130] Example 6: The transmitting device determines the channel monitoring type according to the type of first information, wherein the first information includes a channel and / or a signal.

[0131] For example, when the first information is a terminal-specific channel, the transmitting device determines to use directional channel sensing to perform channel sensing, wherein the terminal-specific channel includes a terminal-specific PDCCH and / or a terminal-specific PDSCH.

[0132] For another example, when the first information is a common channel, the transmitting device determines to use omnidirectional channel sensing or directional channel sensing to perform channel sensing.

[0133] For another example, when the first information is SSB or CSI-RS, the transmitting device determines to use a channel-free listening method to occupy the channel.

[0134] It should be noted that for terminal-specific channels, especially in high frequency bands, their directionality is more obvious, and directional channel sensing is preferably used for channel sensing. For common channels, since their coverage is wider, their transmission beams are often wider than the transmission beams of terminal-specific channels, and they can use directional channel sensing or omnidirectional channel sensing. For signals with short transmission times, such as SSB or CSI-RS, since the time required to occupy the channel to send the signal is short, channel occupancy can be performed using LBT free.

[0135] Optionally, in Example 6, the first information may be an uplink channel and / or an uplink signal, and the first information may also be a downlink channel and / or a downlink signal. In addition, the first information may be information to be sent, such as a signal to be sent, a channel to be sent, etc. Of course, the first information may also be some other information, such as a sent signal, a sent channel, etc.

[0136] Therefore, in the solution of Example 6, the network device or the terminal device can determine the channel listening type according to the type of the first information, thereby adopting a suitable channel listening type to improve the utilization rate of the channel.

[0137] Optionally, in some embodiments of the present application, when the transmitting device determines to use free channel sensing, the transmitting device determines to use omnidirectional channel sensing or directional channel sensing for channel sensing according to time information.

[0138] Specifically, when omnidirectional channel sensing or directional channel sensing is successful, the transmitting device continues to use free channel sensing to occupy the channel; or, when omnidirectional channel sensing or directional channel sensing fails, the transmitting device determines to use omnidirectional channel sensing or directional channel sensing to perform channel sensing.

[0139] It should be noted that the success of omnidirectional channel sensing or directional channel sensing does not necessarily refer to a single successful sensing, but may also refer to the number of successful sensing within a period of time reaching a threshold value, and then the sensing is determined to be successful. Of course, a timer can also be combined to determine the success of omnidirectional channel sensing or directional channel sensing. For details, please refer to the relevant description in the above example 2, which will not be repeated here.

[0140] Similarly, when omnidirectional channel listening or directional channel listening fails: it does not necessarily refer to a single listening failure, but may also refer to the number of listening failures within a period of time reaching a threshold value, then the listening failure is determined. Of course, a timer can also be combined to determine the failure of omnidirectional channel listening or directional channel listening. For details, please refer to the relevant description in the above example 1, which will not be repeated here.

[0141] It should be noted that the time information can be determined by the configured period and time offset, that is, when the transmitting device determines to use the channel-free sensing, the transmitting device can periodically sense the channel, such as periodically using omnidirectional channel sensing or directional channel sensing to sense the channel. In this way, the channel load can be accurately judged, possible interference to other devices can be avoided, and fairness in channel use can be ensured.

[0142] Optionally, in some embodiments of the present application, the transmitting device determines to switch from the channel listening state to the channel non-listening state according to the measurement result; or, the transmitting device determines to switch from the channel non-listening state to the channel listening state according to the measurement result.

[0143] For example, if the measurement results for a period of time are good, the transmitting device determines to switch from the channel listening state to the channel non-listening state according to the measurement results. For another example, if the measurement results for a period of time are poor, the transmitting device determines to switch from the channel non-listening state to the channel listening state according to the measurement results.

[0144] It should be noted that the channel listening state may be, for example, an omnidirectional channel listening state or a directional channel listening state. The channel non-listening state may be, for example, a state where channel listening is exempted or channel listening is not performed.

[0145] Optionally, the measurement result is used to reflect the occupancy status of the channel, or the measurement result is used to reflect the channel quality.

[0146] Optionally, the measurement result includes but is not limited to at least one of the following:

[0147] The measurement results for RSSI, the measurement results for channel occupancy, the measurement results for CSI-RS, and the measurement results for SRS.

[0148] For example, the measurement result for the CSI-RS may be a CQI.

[0149] Therefore, in an embodiment of the present application, the transmitting device can flexibly select the channel listening type from omnidirectional channel listening, directional channel listening, and channel-free channel listening to cope with changes in channel usage and improve channel utilization and transmission efficiency.
