[0037] In addition, in order to facilitate the understanding of the technical solutions of the present application, the related technologies mentioned in the technical solutions of the present application are briefly described as follows.

[0038] Based on this, the technical solutions provided by the embodiments of the present application will be described in detail in combination with the drawings and some embodiments and application scenarios.

[0039] As shown in FIG. 2, a flowchart of a resource sharing method 200 provided by an exemplary embodiment of the present application is shown, which can be executed by the first communication device, but is not limited thereto, and can be executed by at least one of hardware and software installed in the first communication device. In the embodiment, the method 200 can at least include the following steps.

[0040] S210, the first communication device performs communication transmission on the target resource of the licensed frequency band.

[0041] The first communication device can be a device corresponding to the first RAT or the second RAT, such as a terminal, a network side device, etc. which performs wireless transmission access using the first RAT or the second RAT.

[0042] In this embodiment, the first RAT can be, but is not limited to, a wireless access technology for future communication, such as a 6G related wireless transmission technology. The second RAT can include, but is not limited to, at least one of NR, LTE, and a 6G related wireless transmission technology. Among them, the 6G related wireless access technology can be, but is not limited to, a non-terrestrial communication network (Non-Terrestrial Networks, NTN), integrated sensing and communication (Integrated sensing and communication, ISAC), artificial intelligence Internet of things (Artificial Intelligence Internet of things, AIOT), etc.

[0043] In some embodiments, when the first communication device is a device corresponding to the first RAT, the target resource can be a resource corresponding to the second RAT. Alternatively, when the first communication device is a device corresponding to the first RAT or the second RAT, the target resource can also be a resource shared by the first RAT and the second RAT. That is, for a communication system supporting multiple RATs, when the first communication device in the communication system supports the first RAT, the spectrum resources corresponding to a certain RAT can be shared to achieve full utilization of spectrum resources in the licensed frequency band; when the first communication device in the communication system supports the first RAT or the second RAT, the shared spectrum resources between multiple different RATs can also be shared to achieve full utilization of spectrum resources in the licensed frequency band, thereby solving the problem of spectrum resource shortage in future communication systems, improving the utilization rate of spectrum resources, and improving the performance of the communication system.

[0044] In some embodiments, for the case where the target resource is a resource corresponding to the second RAT, the granularity of the target resource (such as time domain resource, frequency domain resource) can be related to a reference subcarrier spacing (Subcarrier Spacing, SCS), so that the first communication device determines the size, position, etc. of the target resource based on the reference subcarrier spacing when sharing the resource. Among them, the reference subcarrier spacing can be the subcarrier spacing adopted by the first communication device, or the subcarrier spacing adopted by the second communication device corresponding to the second RAT, or a subcarrier spacing configured by a higher layer or agreed by a protocol, etc., which is not limited here.

[0045] Similarly, for the case that the target resource is a resource shared by the first RAT and the second RAT, the granularity of the target resource (such as a time domain resource or a frequency domain resource) can be related to a reference subcarrier spacing. The reference subcarrier spacing can be a subcarrier spacing adopted by the first communication device, or a subcarrier spacing configured by a higher layer or agreed by a protocol, and the like, which is not limited herein.

[0046] In some embodiments, the target resource can include at least one of a time domain resource or a frequency domain resource. For example, in the present embodiment, the target resource can include at least M time domain units and Y frequency domain units. The M frequency domain units can include at least a time domain resource or a time length required for transmission by the first communication device, and the Y frequency domain units can include at least a frequency domain resource required for transmission by the first communication device, thereby ensuring that the first communication device can achieve its transmission requirements based on the target resource. M and Y are integers greater than or equal to 1.

[0047] The frequency domain unit can be, but is not limited to, a resource block (RB), a physical resource block (PRB), a resource block set (RB set), a subband, a bandwidth part (BWP), or the like. Alternatively, the frequency domain unit can be in units of MHz, Hz, or the like, which is not limited herein.

[0048] The time domain unit can be a symbol, a slot, a subframe, a frame, or the like. The size of the time domain unit can be related to a reference subcarrier spacing, or the size of the time domain unit can be in units of nanoseconds (ns), microseconds (us), milliseconds (ms), seconds (s), or the like, which is not limited herein.

[0049] Based on this, when the first communication device communicates on the target resource in the licensed frequency band, the first communication device can determine whether to share the target resource or determine the target resource that can be shared by one or more of the following methods: detecting the transmission on the target resource, requesting a shared resource, sending resource allocation information by the second communication device, reducing the transmission power, and predicting the transmission on the target resource. In this way, the full utilization of the spectrum resource is achieved, and the fairness of the spectrum resource sharing in the licensed frequency band is further ensured. The implementation process of each method will be described below with reference to the accompanying drawings and embodiments.

[0050] In some embodiments, if the first communication device determines whether to share the target resource by detecting a transmission on the target resource, the process in which the first communication device communicates on the target resource in the licensed frequency band in S210 can at least include S2101 shown in FIG. 3, and the content is as follows.

[0051] In S2101, the first communication device determines whether to share the target resource according to the detection result (or sensing result, etc.) on the target resource, to ensure fairness when sharing the spectrum resource in the licensed frequency band, and to avoid affecting the transmission of the existing or existing communication device on the target resource.

[0052] In S2101, the first communication device determines whether to share the target resource according to the detection result (or sensing result, etc.) on the target resource, to ensure fairness when sharing the spectrum resource in the licensed frequency band, and to avoid affecting the transmission of the existing or existing communication device on the target resource.

[0053] In the embodiment, the detection result can include, but is not limited to, at least one of the power detected by the first communication device on the target resource, whether a first signal is detected on the target resource, and the content carried in the second signal detected on the target resource.

[0054] In some implementations, for the case where the detection result includes the power detected by the first communication device on the target resource, the process in which the first communication device determines whether to share the target resource according to the detection result on the target resource in S2101 can at least include: if the power detected on the target resource is greater than or equal to a first threshold, it means that the channel corresponding to the target resource is busy or the target resource is unavailable, then the first communication device can determine that the target resource cannot be shared; otherwise, if the transmission power detected on the target resource is less than the first threshold, it means that the channel corresponding to the target resource is not busy or the target resource is available, then the first communication device can determine that the target resource can be shared, thereby ensuring fairness when sharing the spectrum resource in the licensed frequency band.

[0055] The size of the first threshold can be related to one or more of the size of the time domain unit, the number of time domain units (e.g., M), the size of the frequency domain unit, and the number of frequency domain units (e.g., N) included in the target resource detected by the first communication device. For example, the first threshold can be the sum of the received power on M time domain units and Y frequency domain units.

[0056] Alternatively, the size of the first threshold can be irrelevant to one or more of the size of the time domain unit, the number of time domain units (e.g., M), the size of the frequency domain unit, and the number of frequency domain units (e.g., N) included in the target resource detected by the first communication device. For example, the size of the first threshold can be the average received power on M time domain units and Y frequency domain units.

[0057] It is worth noting that for the case where the target resource is a resource corresponding to the second RAT, the aforementioned "power detected on the target resource" can include the power of one or more devices corresponding to the second RAT when transmitting on the target resource in the licensed frequency band. For the case where the target resource is a resource shared by the first RAT and the second RAT, the aforementioned "power detected on the target resource" can include the power of one or more devices corresponding to the first RAT and the second RAT when transmitting on the target resource in the licensed frequency band.

[0058] In some implementations, for the case where the detection result includes whether the first signal is detected on the target resource, the process of determining whether to share the target resource according to the detection result on the target resource in S2101 can at least include: if the first signal is detected on the target resource, determining that the first communication device cannot share the target resource (or can share the target resource); otherwise, determining that the target resource can be shared (or cannot be shared), thereby ensuring fairness when sharing spectrum resources in the licensed frequency band.

[0059] Based on this, as an optional implementation manner, if the target resource is a resource corresponding to the second RAT, and the first communication device is a device corresponding to the first RAT, the first signal can be one or more of a signal (such as a synchronization signal block (SSB), a channel state information reference signal (CSI-RS), a sounding reference signal (SRS), a resource sharing dedicated signal (or resource sharing dedicated signaling, etc.) and the like) sent by a second communication device corresponding to the second RAT.

[0060] As another optional implementation manner, if the target resource is a resource shared by the first RAT and the second RAT, and the first communication device is a device corresponding to the first RAT or the second RAT, the first signal can be a resource sharing dedicated signal.

[0061] It is worth noting that the aforementioned "resource sharing dedicated signal" can be understood as a signal specially introduced by the first communication device for determining whether to share the target resource in the resource sharing process in the present application.

[0062] In some implementation manners, for the case that the detection result includes the content carried in the second signal detected on the target resource, the manner in which the first communication device determines whether to share the target resource according to the detection result on the target resource in S2101 can at least include that the first communication device can determine whether to share the target resource according to the content (such as sharing resource related information, etc.) carried in the second signal detected on the target resource, thereby ensuring the fairness when the spectrum resource on the licensed frequency band is shared.

[0063] Optionally, the content carried in the second signal can include but is not limited to one or more of the related information of resource sharing, such as time-frequency resource information of the first communication device, first indication information, second indication information, third indication information, etc.

[0064] The time-frequency resource information of the first communication device can be understood as time-frequency resource information that can be shared by the first communication device, such as at least one of time-frequency resource periodicity information, time-frequency resource offset information, a time domain start position, a time domain end position, a time domain length, a frequency domain start position, a frequency domain end position, and a frequency domain length. Based on this, if the time-frequency resource information of the first communication device is carried in the second signal, the first communication device can determine the target resource that can be shared according to the time-frequency resource information, and perform resource sharing. In this way, while achieving full utilization of spectrum resources, fairness is ensured when spectrum resources on the licensed frequency band are shared.

[0065] The first indication information is used to indicate the busy state of the target resource. Based on this, if the first indication information indicates that the target resource is busy, it is determined that the target resource cannot be shared, and vice versa. In this way, while achieving full utilization of spectrum resources, fairness is ensured when spectrum resources on the licensed frequency band are shared.

[0066] The second indication information is used to indicate the occupation information of the target resource. Based on this, if the second indication information indicates that the target resource is occupied, it is determined that the target resource cannot be shared; if the second indication information indicates that the target resource is not occupied, it is determined that the target resource can be shared; and if the second indication information indicates that the target resource is partially occupied, the first communication device can determine whether the part of the target resource that is not occupied meets the transmission requirement, and if so, it is determined that the part of the target resource that is not occupied can be shared. In this way, while achieving full utilization of spectrum resources, fairness is ensured when spectrum resources on the licensed frequency band are shared.

[0067] The third indication information is used to indicate the available or unavailable part of the target resource, so as to enable the first communication device to determine whether to share the target resource or whether to share some available resources in the target resource. For example, the third indication information can be used to indicate that 20 slots starting from one slot after receiving the information are unavailable, or to indicate that the first 50 RBs on a carrier within 20 slots starting from one slot after receiving the information are unavailable.

[0068] It can be understood that, similar to the first signal described above, if the target resource is a resource corresponding to the second RAT and the first communication device is a device corresponding to the first RAT, the second signal can be a signal transmitted by a second communication device corresponding to the second RAT, such as one or more of an SSB, a CSI-RS, an SRS, and a resource sharing dedicated signal.

[0069] If the target resource is a resource shared by the first RAT and the second RAT, and the first communication device is a device corresponding to the first RAT or the second RAT, the second signal can be, but is not limited to, a resource sharing dedicated signal.

[0070] In some embodiments, for the case that the first signal and the second signal are resource sharing dedicated signals, the resource sharing dedicated signal can be sent in a fixed position through a dedicated channel, so as to ensure the reliability of the transmission of the resource sharing dedicated signal. In this embodiment, the transmission period of the resource sharing dedicated signal, the frequency domain resource position at the time of transmission, and the like can be configured through high layer signaling, protocol agreement, and the like.

[0071] In addition, the transmission positions of the devices corresponding to different RATs when sending the resource sharing dedicated signal on the target resource can be different. For example, the transmission position of the device corresponding to the RAT with high priority can be earlier than the transmission position of the device corresponding to the RAT with low priority, so as to ensure that the device corresponding to the RAT with high priority utilizes the target resource for its own transmission.

[0072] Based on this, for the first communication device, when detecting the resource sharing dedicated signal, it can only detect the other resource sharing dedicated signal transmission positions before its own resource sharing dedicated signal transmission position, so as to improve the signal detection efficiency.

[0073] In some embodiments, for the detection of the first signal and the second signal, the first communication device can detect according to the configured measurement or detection period, the preconfigured measurement or detection position, so as to ensure the reliability of the detection result.

[0074] In addition, for the case that the target resource is a resource shared by the first RAT and the second RAT, each RAT corresponding device has a corresponding signal (such as the first signal and the second signal) transmission position. Based on this, when detecting whether the target resource is available, the first communication device can only detect those signal transmission positions before its own corresponding signal transmission position. For example, the signal transmission position of the device corresponding to RAT1 is T1, the signal transmission position of the device corresponding to RAT2 is T2, the signal transmission position of the device corresponding to RAT3 is T3, and the signal transmission position of the device corresponding to RAT4 is T4. Among them, T4>T3>T2>T1. Then, if the device corresponding to RAT3 needs to detect whether the target resource is available, it only needs to detect at the positions of T1 and T2, and does not need to consider the T4 position.

[0075] In some embodiments, in addition to the first communication device determining whether to share the target resource according to the detection result on the target resource in S2101, for the case that the first communication device is a terminal, the first communication device can also send the detection result on the target resource to a network side device, and then the network side device determines whether to share the target resource according to the received detection result, and allocates or schedules resources for the first communication device when it is determined that the first communication device can share the target resource, and finally sends the allocated or scheduled resources to the first communication device in the form of a third signal. Correspondingly, when the first communication device receives the third signal sent by the network side device, it can determine whether to share the target resource according to the resource sharing situation of the first communication device indicated by the third signal.

[0076] In addition, the network side device can also indicate whether the first communication device can share the target resource by sending a third signal. If the third signal indicates that the target resource can be shared, the first communication device transmits according to the pre-configured or scheduled resources.

[0077] It is worth noting that the RAT corresponding to the network side device and the RAT corresponding to the first communication device can be the same or different. If the RAT corresponding to the network side device and the RAT corresponding to the first communication device are different, such as the network side device corresponding to the first RAT and the first communication device corresponding to the second RAT, the first communication device can first send the detection result to the network side device corresponding to the second RAT, and then the network side device corresponding to the second RAT and the network side device corresponding to the first RAT interact with the detection result, allocate or schedule resources for the first communication device, or indicate whether the target resource can be shared.

[0078] In some embodiments, for the case of determining whether to share the target resource according to the detection result on the target resource in S2101, if the first communication device determines that the target resource cannot be shared according to the detection result, the first communication device can re-detect on the target resource to re-determine whether to share the target resource according to the detection result, so as to ensure the full use of spectrum resources. For example, the first communication device can re-detect on the target resource after an interval of S time domain units from the current detection process, or can re-detect on the target resource according to a predetermined detection period, such as detecting the power on the target resource, detecting whether the first signal exists on the target resource, detecting whether the second signal exists on the target resource, etc. Wherein, S is an integer greater than or equal to 1.

[0079] Alternatively, if the first communication device determines that the target resource cannot be shared according to the detection result, and determines that the target resource cannot be shared according to the detection result for a plurality of times in succession, the first communication device can increase or prolong the detection interval, and perform detection on the target resource again based on the increased detection interval, so as to avoid waste of detection resources while ensuring full utilization of spectrum resources. The detection interval can be increased by a parameter L agreed by the protocol or configured by the upper layer, for example, assuming that the current detection interval is A, the increased detection interval can be A+L, wherein A and L are integers greater than or equal to 1.

[0080] The detection interval can be increased by at most N*L, wherein N is the maximum number of increases. When the detection interval is increased to A+N*L, the detection interval can be rolled back to A after at least K times of successful transmission of the target resource, wherein N and K are integers greater than or equal to 1.

[0081] In some embodiments, for the case of determining whether to share the target resource according to the detection result on the target resource in S2101, if the first communication device determines to share the target resource according to the first detection result, the first communication device can perform detection on the target resource again, and determine whether to share the target resource according to a second detection result on the target resource, so as to improve the reliability of the target resource sharing result determined by the first communication device.

[0082] In the case where the first detection result is the power size detected on the target resource, the second detection result includes whether a first signal is detected on the target resource or content carried in the second signal detected on the target resource.

[0083] Alternatively, in the case where the first detection result is whether a first signal is detected on the target resource or content carried in the second signal detected on the target resource, the second detection result includes the power size detected on the target resource.

[0084] In some embodiments, for the case where the target resource is a resource shared by the first RAT and the second RAT, when the first communication device determines to share the target resource, the first communication device can send a fourth signal at a corresponding transmission position when transmitting by using the target resource. The fourth signal can include one or more of time-frequency resource information of the first communication device transmission, busy state information of the target resource, occupied information of the target resource, etc., so as to be used by other devices needing to share the target resource to determine whether to share the target resource.

[0085] It is worth noting that, in addition to the aforementioned first communication device determining whether to share the target resource based on one detection result each time, in the embodiment, the first communication device can also determine whether to share the target resource based on two or three different detection results at the same time, such as determining that the power detected on the target resource is less than a first threshold and a first signal is detected on the target resource, and determining that the target resource can be shared, etc., which is not limited herein.

[0086] In some embodiments, for the case that the target resource is the resource corresponding to the second RAT, if the device corresponding to the second RAT (i.e., the second communication device) has a transmission or does not allow or does not expect the first communication device to share the target resource, the second communication device can also perform communication transmission on a specific resource, thereby preventing the first communication device from sharing the target resource. Wherein, the starting position of the specific resource is determined based on the detection position corresponding to the detection result, such as the starting position of the specific resource is not later than the detection position corresponding to the detection result.

[0087] Optionally, the specific resource can have a first time unit as a granularity, wherein the first time unit is the time during which the first communication device can continuously transmit on the target resource.

[0088] In the embodiment, the first communication device determines whether to share the target resource by detecting the transmission on the target resource, which can achieve full utilization of spectrum resources while ensuring the fairness of spectrum sharing on the licensed frequency band. For the case that the target resource is the resource corresponding to the second RAT, the fairness of spectrum sharing can be understood as follows: the present solution can avoid the influence of the first communication device on the transmission of the second communication device corresponding to the second RAT, thereby ensuring the fairness of the transmission of the communication device corresponding to the second RAT on the target resource. For the case that the target resource is shared by the first RAT and the second RAT, the fairness of spectrum sharing can be understood as follows: the present solution ensures that the device corresponding to the first RAT and the device corresponding to the second RAT can enjoy the spectrum resources fairly.

[0089] In some embodiments, if the first communication device determines whether to share the target resource by means of a resource sharing request, the process of the first communication device performing communication transmission on the target resource of the licensed frequency band in S210 can at least include S2102 shown in FIG. 4, the content of which is as follows.

[0090] S2102, the first communication device sends a resource sharing request to the second communication device.

[0091] The first communication device is a device corresponding to the first RAT, the second communication device is a device corresponding to the second RAT, and the target resource is a resource corresponding to the second RAT.

[0092] The resource sharing request is used to request or indicate sharing of the target resource from the second communication device. Optionally, the resource sharing request can include at least one of, but is not limited to, a shareable mode, priority information, time-frequency resource information, and the like.

[0093] The shareable mode can include a semi-static sharing mode and a dynamic sharing mode. The time domain position of the shared resource in the semi-static sharing mode is periodic, and the frequency domain position is fixed. The time-frequency position of the shared resource in the dynamic sharing mode is variable. In this case, the first communication device can perform transmission on the corresponding resource according to the configured time-frequency resource information of the semi-static sharing mode or the dynamically indicated time-frequency resource information of the dynamic sharing mode.

[0094] The priority information includes the priority of the first communication device or the priority of the first communication device transmission. If the priority of the first communication device is higher than the priority of the second communication device, the second communication device should allow the first communication device to share the target resource, otherwise, the second communication device can not allow the first communication device to share the target resource.

[0095] Or, if the priority of the first communication device transmission is higher than the priority of the second communication device transmission, the second communication device should allow the first communication device to share the target resource, otherwise, the second communication device can not allow the first communication device to share the target resource.

[0096] The time-frequency resource information is used to indicate the time-frequency resource position information of the target resource requested by the first communication device, so that the second communication device can determine whether to allow the first communication device to share the target resource according to the time-frequency resource information. For example, if the time-frequency resource information conflicts with the time-frequency resource information corresponding to the transmission of the second communication device, it can be determined not to allow, otherwise, it is determined to allow.

[0097] Optionally, the time-frequency resource information can include at least one of, but is not limited to, period information, offset information, time domain start position, time domain end position, time domain length, frequency domain start position, frequency domain end position, and frequency domain length.

[0098] For the second communication device, after receiving the resource sharing request, it can ignore the information in the resource sharing request and directly default to allow the first communication device to share the target resource. Correspondingly, the first communication device, after sending the resource sharing request, can default that the second communication device allows it to share the target resource.

[0099] Alternatively, the second communication device can also determine whether to allow the first communication device to share the target resource according to its own transmission situation and the information in the resource sharing request, and send the resource sharing response to the first communication device. Then, the first communication device can receive the resource sharing response from the second communication device, where the resource sharing response is used to indicate whether to agree to the resource sharing request of the first communication device. For example, when the resource sharing response is an acknowledgement (ACK), it indicates that the second communication device agrees to the first communication device sharing the target resource; when the resource sharing response is a negative acknowledgement (NACK), it indicates that the second communication device does not agree to the first communication device sharing the target resource.

[0100] In some embodiments, if the first communication device determines to share the target resource by means of the resource sharing request, the first communication device can detect the target resource again when sharing the target resource, and determine whether to share the target resource according to the detection result on the target resource, so as to ensure the reliability of the determined target resource sharing result. It can be understood that the implementation process of the detection result on the target resource can refer to the related description in the foregoing S2101, such as the detection result can include at least one of the power size detected on the target resource, whether a first signal is detected on the target resource, and the content carried in the second signal detected on the target resource. To avoid repetition, it will not be described here.

[0101] In this embodiment, the first communication device determines whether to share the target resource by means of the resource sharing request, which can realize full utilization of spectrum resources while ensuring fairness of spectrum sharing on the licensed frequency band and not affecting the transmission performance of the second communication device.

[0102] In some embodiments, if the first communication device determines whether to share the target resource by means of sending resource allocation information, the process in which the first communication device in S210 communicates and transmits on the target resource of the licensed frequency band can at least include S2103-S2104 shown in FIG. 5, the contents are as follows.

[0103] S2103, the first communication device receives resource allocation information from a second communication device.

[0104] S2104, the first communication device determines the target resource that can be shared according to the resource allocation information.

[0105] In S2103-S2104, the first communication device is a device corresponding to the first RAT, and the second communication device is a device corresponding to the second RAT, such as a terminal or a network side device. The target resource is a resource corresponding to the second RAT.

[0106] In this embodiment, the resource allocation information can include but is not limited to at least one of the following a)-g).

[0107] a) available resource information corresponding to the first communication device, for the first communication device to determine the target resource that can be shared in the resource corresponding to the second RAT according to the available resource information, such as determining part or all of the available resources as the target resource that can be shared.

[0108] b) unavailable resource information corresponding to the first communication device, for the first communication device to determine the target resource that can be shared in the resource corresponding to the second RAT according to the unavailable resource information, such as determining part or all of the resources other than the unavailable resource information in the resource corresponding to the second RAT as the target resource that can be shared.

[0109] c) available resource information corresponding to the second communication device, for the first communication device to determine the target resource that can be shared in the resource corresponding to the second RAT according to the available resource information, such as determining part or all of the resources other than the available resource information in the resource corresponding to the second RAT as the target resource that can be shared.

[0110] d) unavailable resource information corresponding to the second communication device, for the first communication device to determine the target resource that can be shared according to the unavailable resource information, such as determining part or all of the resources corresponding to the unavailable resource information as the target resource that can be shared.

[0111] e) reserved resource information corresponding to the second communication device, for the first communication device to determine the target resource that can be shared according to the reserved resource information, such as determining part or all of the resources other than the reserved resource information in the resource corresponding to the second RAT as the target resource that can be shared.

[0112] f) the second communication device corresponding shareable resource information, for the first communication device to determine the target resource to be shared according to the shareable resource information, such as determining part or all of the shareable resource as the target resource to be shared.

[0113] g) the second communication device corresponding unshareable resource information, for the first communication device to determine the target resource to be shared according to the unshareable resource information, such as determining part or all of the resource corresponding to the second RAT except the unshareable resource as the target resource to be shared.

[0114] Optionally, the second communication device can send the resource allocation information to the first communication device in a manner of broadcast, groupcast, etc., for the first communication device to determine the target resource to be shared. In this embodiment, the resource allocation information can be carried in one or more of the following: System Information Block (SIB) 1, Radio Resource Control (RRC), Downlink Control Information (DCI), Medium Access Control Control Element (MAC CE), etc.

[0115] In some embodiments, if the first communication device determines the target resource to be shared according to the resource allocation information, the first communication device can further detect the target resource when sharing the target resource, and determine whether to share the target resource according to the detection result on the target resource, so as to ensure the reliability of the determined target resource sharing result. It can be understood that the implementation process of the detection result on the target resource can refer to the related description in the foregoing S2101, such as the detection result can include at least one of the power size detected on the target resource, whether a first signal is detected on the target resource, the content carried in the second signal detected on the target resource, etc. To avoid repetition, it will not be described here.

[0116] In this embodiment, the first communication device determines the target resource to be shared by the second communication device sending the resource allocation information, which can realize the full utilization of spectrum resources while ensuring the fairness of spectrum sharing on the licensed frequency band, and avoiding the impact on the transmission of the second communication device.

[0117] In some embodiments, if the first communication device determines whether to share the target resource by reducing the transmission power, the process in which the first communication device performs the communication transmission on the target resource in the licensed frequency band in S210 can at least include S2105 shown in FIG. 6, and the content is as follows.

[0118] S2105, the first communication device performs the communication transmission on the target resource by reducing the transmission power.

[0119] In the embodiment, the first communication device is a device corresponding to the first RAT, such as a terminal or a network side device, and the target resource is a resource corresponding to the second RAT.

[0120] In some embodiments, when the first communication device performs the communication transmission on the target resource by reducing the transmission power, the size of the reduced transmission power can be determined according to the transmission performance of the device corresponding to the second RAT (i.e., the second communication device), so as to ensure that the first communication device does not affect the transmission performance of the second communication device when sharing the target resource to perform the communication transmission.

[0121] For example, the worse the transmission performance of the second communication device is, the smaller the transmission power of the first communication device after reducing the transmission power is, and vice versa.

[0122] In the embodiment, the first communication device shares the target resource by reducing the transmission power, reduces or avoids the interference to the second communication device, and can realize the full utilization of the spectrum resource while ensuring the fairness of the spectrum resource sharing on the licensed frequency band.

[0123] In some embodiments, if the first communication device determines whether to share the target resource by predicting the transmission situation on the target resource, the process in which the first communication device performs the communication transmission on the target resource in the licensed frequency band in S210 can at least include S2106-S2107 shown in FIG. 7, and the content is as follows.

[0124] S2106, the first communication device predicts whether there is a signal transmission on the target resource.

[0125] S2107, determines whether to share the target resource according to the prediction result.

[0126] In the embodiment, if the first communication device is a device corresponding to the first RAT, such as a terminal or a network side device, and the target resource is a resource of the second RAT, the signal transmission can be a signal transmission on the second communication device corresponding to the second RAT.

[0127] If the first communication device is a device corresponding to the first RAT or the second RAT, such as a terminal or a network side device, and the target resource is a resource shared by the first RAT and the second RAT, the signal transmission can be a signal transmission on a device corresponding to the first RAT or a signal transmission on a device corresponding to the second RAT, which is not limited herein.

[0128] In some embodiments, if the first communication device predicts that there is a signal transmission on the target resource, it can be determined that the target resource cannot be shared, otherwise, it can be determined that the target resource can be shared, thereby ensuring the fairness of spectrum resource sharing on the licensed frequency band while achieving full utilization of spectrum resources.

[0129] In some embodiments, if the first communication device determines that the target resource can be shared according to the prediction result, the first communication device can detect the target resource again when it is determined that the target resource can be shared, and determine whether to share the target resource according to the detection result on the target resource, thereby ensuring the reliability of the determined target resource sharing result. It can be understood that the implementation process of the detection result on the target resource can refer to the related description in the foregoing S2101, such as the detection result can include at least one of the power size detected on the target resource, whether a first signal is detected on the target resource, the content carried in the second signal detected on the target resource, etc. To avoid repetition, it will not be described here.

[0130] For the resource sharing mode provided in the foregoing embodiments, the continuous transmission resource (such as time domain resource, frequency domain resource, etc.) on the target resource after the first communication device determines that the target resource can be shared does not exceed a second threshold, thereby avoiding affecting the transmission performance of the existing device on the target resource, that is, the size of the second threshold can be related to the transmission performance of the existing device on the target resource; or the continuous transmission resource on the target resource is not less than a third threshold, thereby ensuring that the continuous transmission resource on the target resource can meet the transmission demand of the first communication device, that is, the size of the third threshold can be related to the transmission demand of the first communication device. The second threshold and the third threshold can be implemented by protocol agreement, high layer configuration, etc., which is not limited herein.

[0131] For example, in the case where the target resource is a resource corresponding to the second RAT, at most X1 time domain units (or at least X2 time domain units) are shared in one transmission, or at most Y1 frequency domain units (or at least Y2 frequency domain units) are shared in one transmission, to avoid affecting the transmission performance of the device corresponding to the second RAT.

[0132] For example, if the target resource is a resource shared by the first RAT and the second RAT, one transmission shares at most X1 time domain units (or at least X2 time domain units), or one transmission shares at most Y1 frequency domain units (or at least Y2 frequency domain units), to avoid affecting the transmission performance of devices corresponding to the first RAT and the second RAT other than the first communication device.

[0133] In some embodiments, if the first RAT shares the resource of the second RAT, the device corresponding to the first RAT (e.g., the first communication device) can reuse at least one of the signals and signaling of the second RAT, such as SSB, reference signal, etc., to achieve signal synchronization, channel measurement, channel estimation, etc.

[0134] Alternatively, the device corresponding to the first RAT can perform rate matching on at least one of the signals and signaling and configured resources of the second RAT to ensure that the transmission performance of the device corresponding to the second RAT is not affected. The signals and signaling and configured resources of the second RAT can include at least one or more of SSB, reference signal, control resource set (CORESET), random access occasion (RACH occasion), etc.

[0135] Alternatively, if a communication device can support simultaneous communication transmission under the first RAT and the second RAT, the communication device can dynamically allocate transmission power for the transmission of the first RAT and the second RAT.

[0136] Based on the foregoing description of the resource sharing method, the technical solutions provided by the present application are further exemplarily introduced below in combination with examples, as follows.

[0137] Example 1

[0138] Assuming that the first communication device is a device corresponding to the first RAT, the second communication device is a device corresponding to the second RAT, and the target resource is a resource of the second RAT, i.e., the first communication device shares the resource of the second RAT, the SCS1 transmitted by the first communication device is 30 KHz, the SCS2 transmitted by the second communication device is 15 KHz, and the configured SCS3 is 60 KHz, then the first communication device can select one of them as a reference subcarrier spacing according to the protocol agreement.

[0139] Then, when the first communication device detects the target resource, the size of the time-frequency resource is determined according to the reference subcarrier spacing. For example, if the first communication device determines that the reference subcarrier spacing is 60 KHz, then the first communication device performs power detection on the first two symbols in a slot and 10 PRBs in each symbol, and the size of each symbol and PRB is determined according to the reference subcarrier spacing of 60 KHz.

[0140] If the detection result is the power on the target resource, the first threshold involved in the power detection can be a threshold of the total power on 20 PRBs in total in the two symbols, a threshold of the average power on the 20 PRBs, or a threshold of the average power on 20*12 resource elements (REs).

[0141] If the detected power is less than the first threshold, the first communication device determines that the target resource, i.e., the resource of the second RAT, can be shared. The frequency domain range of the shareable resource does not exceed 10 PRBs, and the time domain length does not exceed 2 slots (equivalent to 1 / 2 ms). After 2 slots, the first communication device needs to re-detect the resource of the second RAT.

[0142] If the detected power is greater than or equal to the first threshold, the first communication device determines that the target resource cannot be shared, and waits for the first two symbols of the next slot to re-detect, i.e., restarts detection after 12 symbols after the end of the last detection; or the first communication device needs to wait for the first two symbols of the m+1 slot to detect, i.e., restarts detection after (12+m*14) symbols after the end of the last detection.

[0143] It is worth noting that if the first communication device needs one symbol to process the detection result, the earliest position at which the first communication device can start sharing when determining that the target resource can be shared is the fourth symbol in the slot, i.e., the first two symbols are used for detection, the third symbol is used for processing the detection result, and the fourth symbol starts communication transmission.

[0144] In some implementations, the first communication device performs power detection or signal detection at configured locations, and to avoid the first communication device not detecting the transmission of the second communication device, the transmission of the second communication device needs to be limited, for example, if the first communication device performs detection at the first two symbols of a slot, the second communication device performs transmission in slot units, or prohibits mini-slot based transmission whose starting position is not at the slot boundary, so that the first communication device does not start to share the resource of the second RAT because it does not detect the mini-slot based transmission at the first two symbols of the slot.

[0145] Example 2

[0146] Assuming that the first communication device is a device corresponding to the first RAT, the second communication device is a device corresponding to the second RAT, and the target resource is a resource of the second RAT, i.e., the first communication device shares the resource of the second RAT, and the first communication device detects a first signal or a second signal sent by the second communication device at a specific location. Then, if the first signal is detected, the first communication device cannot share the resource of the second RAT before the next detection location.

[0147] In this case, if the device of the second RAT does not want to share the resource, it needs to send the first signal at the specific location to prevent the first communication device from sharing the resource of the second RAT.

[0148] In some embodiments, the second communication device can also notify the first communication device of the detection location of the next first signal in the first signal.

[0149] Example 3

[0150] Assuming that the first communication device is a device corresponding to the first RAT, the second communication device is a device corresponding to the second RAT, and the target resource is a resource of the second RAT, i.e., the first communication device shares the resource of the second RAT, and the first communication device sends a resource sharing request to the second communication device to request or indicate or trigger the second communication device to share the resource of the second RAT.

[0151] The resource sharing request can be a simple request (request). After receiving the request, the second communication device shares the target resource according to the time of the agreed information. For example, the agreed shareable resource is the first 50 PRBs on the carrier, the sharing time length is 10 slots, and the reference subcarrier spacing is 30 KHz. Therefore, the second communication device starts to share the resource after at least Tproc time of receiving the resource sharing request. Tproc is the time for the second communication device to process the resource sharing request.

[0152] Optionally, the second communication device can indicate whether to agree to the resource sharing request of the first communication device by feeding back a resource sharing response. For example, feeding back NACK indicates not to share, and feeding back ACK indicates to share.

[0153] Example 4

[0154] It is assumed that the first communication device is a device corresponding to the first RAT, the second communication device is a device corresponding to the second RAT, and the target resource is a resource of the second RAT. That is, the first communication device shares the resource of the second RAT. It is assumed that the first communication device shares the resource of the second RAT, and the first communication device sends a resource sharing request to the second communication device to request or indicate or trigger the second communication device to share the resource of the second RAT.

[0155] The resource sharing request can include a shareable mode, such as a semi-static sharing mode or a dynamic sharing mode. The semi-static sharing mode can be as shown in Example 3. For the dynamic sharing mode, the first communication device needs to further detect whether the target resource is available before transmission, and the second communication device can not need to specially reserve the resource for the first communication device.

[0156] Optionally, the resource sharing request can further include priority information, such as the priority of the first communication device (or the priority of the transmission of the first communication device) p1 and the priority of the second communication device (or the priority of the transmission of the second communication device) p2. Then, the second communication device can determine whether to share the target resource according to the priority of the first communication device after receiving the resource sharing request. For example, p1 is less than p2, that is, the priority of the first communication device is high, and it is determined that the target resource can be shared. Otherwise, it is determined that the target resource is not shared.

[0157] Optionally, the resource sharing request can further include time-frequency resource information that the first communication device wants to share. Then, the second communication device can use other resources except the resource corresponding to the time-frequency resource information that the first communication device wants to share for its own transmission after receiving the resource sharing request.

[0158] Optionally, the second communication device can indicate whether to agree with the resource sharing request of the first communication device through a feedback resource sharing response, for example, feedback NACK means not to share, and feedback ACK means to share.

[0159] In the present application, by providing a scheme of sharing resources in different RAT scenarios, the problem of resource shortage in future communication systems is effectively solved, the spectrum utilization is improved, and the performance of the communication system is improved.

[0160] As shown in FIG. 8, a flowchart of a method 800 of resource sharing provided by an exemplary embodiment of the present application is shown, which can be executed by the second communication device, but is not limited to this, and can be executed by at least one of hardware and software installed in the second communication device. In the present embodiment, the method 800 can at least include the following steps.

[0163] In an optional implementation, the second communication device shares resources with the first communication device using the target resource of the licensed frequency band, including: the second communication device receives a detection result of the first communication device on the target resource; and sends a third signal to the first communication device according to the detection result, wherein the third signal is used to indicate the resource sharing situation of the first communication device; wherein the second communication device is a network side device, the first communication device is a terminal, and the detection result includes at least one of the following: a power size detected on the target resource; whether a first signal is detected on the target resource; content carried in a second signal detected on the target resource; the first signal includes at least one of the following: a synchronization signal block (SSB); a channel state information reference signal (CSI-RS); a sounding reference signal (SRS); a resource sharing dedicated signal; and the content carried in the second signal includes at least one of the following: time-frequency resource information of the first communication device; first indication information used to indicate a busy state on the target resource; and second indication information used to indicate occupation information on the target resource.

To avoid repetition, the related description is not repeated here.
