[0002] At present, in the sidelink (SL) communication process, before a terminal transmits a signal in frequency range 1 (FR1) with other terminals, the terminal can perform detection in a measurement window of a predetermined duration, and determine channel congestion parameters such as channel busy ratio (Channel Busy Ratio, CBR), channel occupancy ratio (Channel occupancy Ratio, CR), channel occupancy ratio limit value, etc. according to the detection result obtained, so that the terminal can select resources and transmission methods for signal transmission according to the channel congestion parameters, and transmit signals according to the selected resources and transmission methods.

[0003] However, in the scenario where the terminal performs high-frequency signal transmission in frequency range 2 (FR2) with other terminals, there is no specific solution for determining the channel congestion parameters. Thus, before the terminal performs high-frequency signal transmission in FR2 with other terminals, the terminal may not be able to determine the channel congestion parameters. Therefore, the terminal may be unable to select resources and transmission methods for signal transmission, thereby causing the terminal to be unable to perform high-frequency signal transmission, thus resulting in poor transmission reliability of the terminal and poor transmission efficiency of the system. Summary of the invention

[0020] The following will be combined with the drawings in the embodiments of the present application to clearly describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field belong to the scope of protection of this application.

[0021] The terms involved in the embodiments of the present application are explained below.

[0022] 1. Channel Busy Ratio (CBR)

[0023] Usually, the CBR measured in time slot n is defined as: the proportion of sub-channels in a resource pool whose SL-signal strength indication (RSSI) is greater than or equal to the threshold within a CBR measurement window [na,n-1]. Where a is configured by high-level parameters and can be equal to 100slots or 100*2 μ slots.

[0024] In this way, after the terminal determines the CBR, the terminal can adjust the following transmission parameters according to the CBR: the MCS range of the given modulation and coding scheme (MCS) table supported in the resource pool, the range of the number of subchannels, the upper limit of the number of transmissions, the upper limit of the number of retransmissions, and the upper limit of the transmission power (including zero transmission power). In addition, the CBR will also affect the channel occupancy ratio (CR) limit value.

[0025] From the above content, it can be seen that the measurement result of CBR can directly affect the amount of resources selected by the terminal and the transmission method.

[0026] 2. SL-RSSI

[0027] Typically, SL-RSSI is defined as the linear average of the total received power of OFDM symbols configured as the Physical Sidelink Control Channel (PSCCH) and the Physical Sidelink Shared Channel (PSSCH) starting from the second Orthogonal Frequency-Division Multiplexing (OFDM) symbol in the time slot where the configured subchannel is located.

[0028] 3. Channel occupancy ratio (CR)

[0029] Typically, the CR measured in time slot n is defined as: at the current time n, if the priority of the terminal's data to be transmitted is q, it is necessary to count the number of resources A used by the terminal for transmission of services with a priority of q in the time period [na, n-1], and to count the number of resources B reserved by the terminal for transmission of services with a priority of q in the time period [n, n+b]; the total number of resources in the time period [na, n+b] is C, and the CR for priority q is (A+B) / C.

[0030] The calculation of CR is based on the priority of the terminal transmission service, that is, for each service priority, a corresponding CR will be calculated.

[0031] Thus, when reserving resources, assuming that the priority of the service currently to be transmitted is q, the following CR limit value needs to be met:

[0032] ∑ i≥q CR(i)≤CR Limit (q)

[0033] Among them, CR Limit (q) is configured by high-level parameters. This limit means that the sum of the CRs corresponding to services with a priority less than or equal to q is limited to or less than the CRs corresponding to services with a priority of q. This limit is used for congestion control on the SL to prevent a user from occupying too many resources.

[0034] It should be noted that CBR and CR are measured and calculated within a certain resource pool.

[0035] 4. Beam

[0036] Due to the scarcity of low-frequency resources, 5G New Radio (NR) uses high-frequency bands such as millimeter waves. Since the propagation loss of high-frequency bands is greater than that of low-frequency bands, its coverage distance is worse than that of Long Term Evolution (LTE). To solve this problem, one solution is that 5G uses multi-antenna beamforming to enhance the signal and thus enhance coverage. At present, beamforming is a signal processing technology that uses a sensor array to send and receive signals in a directional manner. Beamforming technology adjusts the parameters of the basic unit of the phase array so that signals at certain angles obtain constructive interference, while signals at other angles obtain destructive interference, so that the antenna beam points in a specific direction.

[0037] 5. Transmission Configuration Indication (TCI)

[0038] Usually, in the Uu interface, TCI can be indicated by downlink control information (DCI), and TCI will be associated with a reference signal. The physical downlink shared channel (PDSCH) / physical uplink shared channel (PUSCH) scheduled by DCI and the reference signal corresponding to TCI are quasi-colocation (QCL). In other words, the beam of the reference signal is the same as the beam of the PDSCH, so through TCI, the terminal can know which beam to use to receive data. The TCI used to control the beam of PDSCH is called the downlink TCI (DLTCI), and the TCI used to control the beam of PUSCH is called the uplink TCI (ULTCI), and PUSCH / PDSCH is also allowed to share the same set of TCI, which can be simply called TCI.

[0039] The base station can enable the terminal to switch to different beams by modifying TCI, but this process may involve DCI decoding and beam switching. Therefore, the switching beam will not take effect immediately after sending / receiving TCI. Instead, it requires a certain amount of processing time, and the terminal cannot send / receive during the processing time.

[0045] The following is a detailed description of the channel congestion parameter determination method provided by the embodiment of the present application through some embodiments and their application scenarios in combination with the accompanying drawings.

[0046] The channel congestion parameter determination method provided in the embodiment of the present application can be executed by a channel congestion parameter determination device, or a terminal, or a functional module or entity in the terminal. In the embodiment of the present application, the channel congestion parameter determination method provided in the embodiment of the present application is illustrated by taking the execution of the channel congestion parameter determination method by the terminal as an example.

[0047] Figure 2 FIG. 1 is a flow chart showing a method for determining a channel congestion parameter provided by an embodiment of the present application. Figure 2 As shown, a method for determining a channel congestion parameter provided by an embodiment of the present application may include the following step 101.

[0048] Step 101: The terminal determines a first channel congestion parameter.

[0049] In some embodiments of the present application, during the SL communication process, when the terminal is configured with a resource pool of the FR2 frequency band, before the terminal uses the time-frequency domain resources in the resource pool to transmit with other terminals, the terminal can first determine the first channel congestion parameter corresponding to the transmitting beam based on the transmitting beam used for signal transmission, so as to judge or determine whether the terminal uses the transmitting beam for transmission.

[0050] In some embodiments of the present application, the first channel congestion parameter may be a channel congestion parameter corresponding to the transmit beam, or may be a channel congestion parameter corresponding to all transmit beams associated with the terminal; wherein the number of the transmit beams may be at least one.

[0051] In some embodiments of the present application, the above-mentioned first channel congestion parameter may include at least one of the following: a first channel busy ratio, a first channel occupancy rate limit value, and a first channel occupancy rate.

[0052] It can be understood that the first channel busy ratio can be the channel busy ratio corresponding to the above-mentioned transmission beam, or can be the channel busy ratio corresponding to all transmission beams associated with the terminal. The first channel occupancy limit value can be the channel occupancy limit value corresponding to the above-mentioned transmission beam, or can be the channel occupancy limit value corresponding to all transmission beams associated with the terminal. The first channel occupancy can be the channel occupancy corresponding to the above-mentioned transmission beam, or can be the channel occupancy corresponding to all transmission beams associated with the terminal.

[0053] In the embodiment of the present application, the first channel congestion parameter is determined by at least one of the following:

[0054] The number of first resources whose measurement results within the first time window are greater than a first threshold value;

[0055] Default parameters;

[0056] The number of first transmission resources within the second time window.

[0057] In some embodiments of the present application, the first time window may be a continuous time window. For example, when the terminal determines the first channel congestion parameter in slot n, the first time window may be [na, n-1], where a = x*100 slots or x*100*2 μ slots.

[0058] In some embodiments of the present application, the first time window may be a non-continuous time window. For example, the first time window is only composed of the time window portion associated with the transmit beam.

[0059] In some embodiments of the present application, the time length of the above-mentioned first time window is determined based on a first parameter; wherein the first parameter is related to the period of beam switching of the terminal.

[0060] Optionally, the first parameter may be a positive integer or a decimal. For example, if multiple beams associated with the terminal can be polled once within 200 slots, the first parameter may be set to 2.

[0061] It can be seen that when it is stipulated in the embodiment of the present application that the time length of the first time window is determined based on the first parameter related to the period of the beam switching of the terminal, this can avoid the situation where the terminal is unable to determine the time length of the first time window, and therefore, can avoid the situation where the terminal is unable to determine the first channel congestion parameter.

[0062] In the embodiment of the present application, the above-mentioned first resource includes at least one of the following: a resource associated with the first object and a resource associated with the terminal.

[0063] In some embodiments of the present application, the above-mentioned first resource may include at least one of the following: a sub-channel, a physical resource block (PRB), etc.

[0064] In some embodiments of the present application, the above-mentioned first object includes at least one of the following: a first beam, a second object; wherein the second object includes at least one of the following: a reference signal, a transmission configuration indication, a first identifier, a hybrid automatic repeat request process, a transmission block, an authorization, and the first identifier is an identifier of the terminal, or an identifier of other terminals communicating with the terminal.

[0065] Optionally, the first beam may specifically be a transmit beam or a receive beam. When the first beam is a transmit beam, the first beam may be the transmit beam to be used by the terminal for signal transmission; when the first beam is a receive beam, the transmit beam corresponding to the first beam may be the transmit beam to be used by the corresponding terminal for signal transmission. It should be noted that the detection or reception based on the beam by the terminal is actually based on the reference signal or resource of a certain configured TCI for detection or reception. Transmission based on the beam is actually the transmission channel or resource being transmitted in a quasi-co-addressed manner with a certain reference signal. In other words, the beam in the embodiment of the present application can be understood as transmission, detection, or reception based on a certain TCI configuration or QCLtype. The resources associated with the beam can also be considered as resources associated with a certain reference signal (Channel State Information-ReferenceSignal (CSI-RS) / Demodulation Reference Signal (DMRS) / S-SSB) / TCI / QCL type / Terminal Identifier).

[0066] Among them, when the first channel congestion parameter is the first channel busy ratio, the first beam can be specifically a receiving beam, and when the first channel congestion is the first channel occupancy rate, the first beam can be specifically a transmitting beam. It can be understood that when calculating the CBR corresponding to the receiving beam or its corresponding transmitting beam, the terminal needs to use the receiving beam to detect or determine the received signal strength indication of the sub-channel resources within the time window, so as to calculate the CBR corresponding to the receiving beam or its corresponding transmitting beam. When calculating the CR corresponding to the beam, the terminal needs to calculate the proportion of the resources that have been sent and the resources to be sent within the time window, and these resources are related to the transmitting beam.

[0067] Optionally, the second object may be: an object associated with the first beam, and / or an object associated with the terminal. It can be understood that due to the beam, it can be understood as sending, detecting, or receiving based on a certain TCI configuration or QCLtype. The resources associated with the beam can also be considered as resources associated with the second object such as the reference signal or TCI or QCLtype or terminal identifier, and can be further understood as resources associated with the second object associated with the beam.

[0068] Optionally, the above resources may specifically be time-frequency domain resources, such as subchannels or PRBs.

[0069] Optionally, when the first beam is a receiving beam, the above-mentioned first identifier can specifically be the identifier of the terminal, that is, the first identifier can specifically be the source ID; when the first beam is a transmitting beam, the above-mentioned first identifier can specifically be the identifier of other terminals communicating with the terminal, that is, the first identifier can specifically be the destination identifier destination ID.

[0070] In some embodiments of the present application, when the second object includes a first identifier, the resource corresponding to the second object is: the resource associated with the second identifier; wherein the second identifier is an identifier indicated by a higher layer (eg, a media access control (MAC) layer).

[0071] It can be seen that, since the various objects included in the first object are specified in the embodiment of the present application, this can avoid the situation where the terminal is unable to determine the object to be measured. Therefore, it can avoid the situation where the terminal is unable to determine the congestion parameter of the first channel due to the inability of the terminal to perform measurement.

[0072] In some embodiments of the present application, the resource associated with the first object includes at least one of the following:

[0073] resources associated with the first beam or its corresponding beam;

[0074] The resource corresponding to the second object;

[0075] The resources associated with the first beam group.

[0076] In some embodiments of the present application, the resources associated with the first beam or its corresponding beam may include resources used by the first beam or its corresponding beam.

[0077] In an embodiment of the present application, the first beam group includes at least one of the following items associated with the first beam: a receiving beam and a transmitting beam. The resources associated with the first beam group may include: resources used by the first beam group. The first beam group may be a beam group configured by other devices (e.g., network side devices, other terminals, etc.).

[0078] Optionally, when the first beam is a receiving beam, the receiving beam associated with the first beam can be understood as a receiving beam adjacent to the first beam, and the transmitting beam associated with the first beam can be understood as a transmitting beam corresponding to the first beam. When the first beam is a transmitting beam, the transmitting beam associated with the first beam can be understood as a transmitting beam adjacent to the first beam, and the receiving beam associated with the first beam can be understood as a receiving beam corresponding to the first beam. Alternatively, the first beam group is predefined by a protocol, or preconfigured by a network, or configured by a network.

[0079] It can be seen that, since the resources associated with the first object are specified in the embodiment of the present application, this can avoid the situation where the terminal is unable to determine the resources for measurement. Therefore, it can avoid the situation where the terminal is unable to determine the congestion parameter of the first channel due to the inability of the terminal to perform measurement.

[0080] In some embodiments of the present application, the above default parameters may be agreed upon by the protocol, configured by the network side device, pre-configured by the network side device, or determined by the terminal.

[0081] In the embodiment of the present application, the above-mentioned first transmission resource includes at least one of the following: a transmission resource associated with the first object, and all transmission resources associated with the terminal.

[0082] In some embodiments of the present application, the above-mentioned first object includes at least one of the following: a first beam, a second object; wherein the second object includes at least one of the following: a reference signal, a transmission configuration indication, a first identifier, a hybrid automatic repeat request process, a transmission block, an authorization, and the first identifier is an identifier of the terminal, or an identifier of other terminals communicating with the terminal.

[0083] It should be noted that, for the description of the first object and the second object, reference may be made to the specific description in the above embodiment, and the embodiments of the present application will not be repeated here.

[0084] In some embodiments of the present application, the transmission resource associated with the first object includes at least one of the following:

[0085] transmission resources associated with the first beam or a beam corresponding to the first beam;

[0086] transmission resources corresponding to the second object;

[0087] The transmission resources associated with the first beam group.

[0088] In some embodiments of the present application, the transmission resources associated with the above-mentioned first beam or its corresponding beam may include the transmission resources used by the first beam or its corresponding beam.

[0089] In the embodiment of the present application, the above-mentioned first beam group includes at least one of the following items associated with the first beam: a receiving beam and a transmitting beam.

[0090] In the embodiment of the present application, the transmission resources associated with the above-mentioned first beam group may include: the transmission resources used by the first beam group.

[0091] It can be seen that since the transmission resources associated with the first object are specified in the embodiment of the present application, this can avoid the situation where the terminal is unable to determine the transmission resources for detection. Therefore, it can avoid the situation where the terminal is unable to determine the congestion parameters of the first channel due to the terminal's inability to perform detection.

[0092] The embodiment of the present application provides a method for determining a channel congestion parameter, and the terminal can determine the first channel congestion parameter based on at least one of the number of first resources whose measurement results in the first time window are greater than the first threshold value, default parameters, and the number of first transmission resources in the second time window; wherein the first resource includes at least one of the following: resources associated with the first object, resources associated with the terminal; the first transmission resource includes at least one of the following: transmission resources associated with the first object, all transmission resources associated with the terminal. Since the terminal can determine the first channel congestion parameter based on at least one of the number of resources associated with the first object and / or resources associated with the terminal whose measurement results in the first time window are greater than the first threshold value, default parameters, and the number of transmission resources associated with the first object and / or all transmission resources associated with the terminal in the second time window, the congestion degree in the resource pool can be more accurately evaluated, and then it can be determined whether to transmit, so that the transmission reliability of the terminal and the transmission efficiency of the system can be improved.

[0093] The following will use examples to illustrate specific solutions for the terminal to determine the first channel congestion parameter when the first channel congestion parameter is different parameters.

[0094] Example 1: The congestion parameter of the first channel is the busy ratio CBR of the first channel.

[0095] In the related art, the CBR calculation mechanism of SL is performed based on the background of the terminal performing omnidirectional detection in the FR1 frequency band. When the terminal operates in the FR2 frequency band, due to the directionality of the beam, the terminal's perception of channel congestion and channel occupancy are both directional. At this time, the existing CBR calculation method may no longer be accurate, which affects the subsequent resource allocation, and may affect the transmission reliability of the terminal and the transmission efficiency of the system.

[0096] In order to solve the above technical problem, in some embodiments of the present application, the above first channel congestion parameter includes a first channel busy ratio, and the first channel busy ratio is determined according to at least one of the following:

[0097] The number of first resources whose measurement results within the first time window are greater than a first threshold value;

[0098] Default parameters.

[0099] In some embodiments of the present application, the above measurement result may specifically be: an RSSI value obtained by measuring the first resource.

[0100] Solution 1: Calculate channel busy ratio by beam

[0101] In the present solution, calculating the channel busy ratio according to the beam can be understood as calculating the relevant channel busy ratio based on a specific beam, such as a transmitting beam, that is, calculating the channel busy ratio based on the resources associated with the first object, or calculating the channel busy ratio for each beam of at least part of the associated beam. For example, each beam corresponds to a channel busy ratio, and the terminal calculates the channel busy ratio corresponding to each beam according to the resources corresponding to each beam. It can be understood that compared with the related art, in the present solution, the channel busy ratio takes into account the factor of the beam direction, rather than being performed according to the background of omnidirectional detection. Therefore, the accuracy of the channel busy ratio calculated during beam transmission can be improved.

[0102] The following will take the calculation of the channel busy ratio (ie, the first channel busy ratio) corresponding to a certain transmission beam used by the terminal for signal transmission as an example for explanation.

[0103] In some embodiments of the present application, the first channel busy ratio is determined based on the number of first resources whose measurement results within the first time window are greater than the first threshold value. Wherein, when the first resource is a resource associated with the first object, the calculation of the first channel busy ratio satisfies at least one of the following:

[0104] The ratio of the number of first resources whose measurement results within the first time window are greater than the first threshold value to the number of all resources within the first time window;

[0105] The ratio of the number of first resources whose measurement results in the first time window are greater than the first threshold value to the number of all resources in the third time window;

[0106] The ratio of the number of first resources whose measurement results in the first time window are greater than the first threshold value to the number of all resources in the fourth time window;

[0107] The ratio of the number of first resources whose measurement results in the first time window are greater than the first threshold to the number of all resources in the fifth time window.

[0108] Optionally, the first channel busy ratio may specifically be: a ratio of the number of first resources whose measurement results within the first time window are greater than a first threshold value to the number of all resources within the first time window.

[0109] It can be seen that since the calculation of the first channel busy ratio is based on the number of first resources whose measurement results within the first time window are greater than the first threshold value, rather than based on the number of all resources whose measurement results within the first time window are greater than the first threshold value, that is to say, the first channel busy ratio calculation mechanism in the embodiment of the present application is based on the beam direction, rather than being performed based on the background of omnidirectional detection, therefore, the accuracy of the calculated first channel busy ratio can be improved.

[0110] In the embodiment of the present application, the third time window is: a time window associated with the first object in the first time window.

[0111] Optionally, the time window associated with the first object may be understood as a time window used to measure the first object.

[0112] Optionally, the third time window may be a continuous time window or a discontinuous time window. It is understandable that the time window associated with the first object may be discontinuous within the first time window.

[0113] Optionally, the first channel busy ratio may specifically be: a ratio of the number of first resources whose measurement results within the first time window are greater than a first threshold value to the number of all resources within the third time window.

[0114] Thus, it can be known that since the calculation of the first channel busy ratio is based on the number of first resources whose measurement results in the first time window are greater than the first threshold value, and the number of all resources in the third time window, rather than based on the number of all resources whose measurement results in the first time window are greater than the first threshold value, and the number of all resources in the first time window, that is, the first channel busy ratio calculation mechanism in the embodiment of the present application is directional, rather than being performed in the background of omnidirectional detection, and therefore, the accuracy of the calculated first channel busy ratio can be improved. It can be understood that this scheme can also be described as the calculation of the first channel busy ratio is based on the number of first resources whose measurement results in the third time window are greater than the first threshold value, and the number of all resources in the third time window.

[0115] In the embodiment of the present application, the fourth time window includes a third time window and a sixth time window, and the sixth time window is: a time window associated with the first object that is located before the first time window and is closest to the first time window.

[0116] In some embodiments of the present application, the sixth time window may specifically be: a time window located before the first time window and a time window in which the first beam is most recently measured.

[0117] It can be understood that when the time length of the third time window contained in the first time window does not reach a certain threshold value, the terminal can also select a sixth time window from the time window of the associated first object that is closest to the first time window and is located before the first time window, so that the sum of the time lengths of the third time window and the sixth time window reaches the certain threshold value, that is, the time length of the fourth time window reaches the certain threshold value.

[0118] Optionally, the first channel busy ratio may specifically be: a ratio of the number of first resources whose measurement results within the first time window are greater than a first threshold value to the number of all resources within the fourth time window.

[0119] It can be seen that since the calculation of the first channel busy ratio is based on the number of first resources whose measurement results in the first time window are greater than the first threshold value, and the number of all resources in the fourth time window, rather than being based on the number of all resources whose measurement results in the first time window are greater than the first threshold value, and the number of all resources in the first time window, that is, the first channel busy ratio calculation mechanism in the embodiment of the present application is directional, rather than being performed in the background of omnidirectional detection, therefore, the accuracy of the calculated first channel busy ratio can be improved.

[0120] In an embodiment of the present application, the above-mentioned fifth time window is any one of the following: the seventh time window, the eighth time window, and the ninth time window, the seventh time window is the time window corresponding to the DRX activation time within the discontinuous reception (DRX) cycle, the eighth time window is the time window for measurement within the DRX cycle, and the ninth time window includes: the time window where the seventh time window overlaps with the third time window or the time window where the eighth time window overlaps with the third time window.

[0121] Optionally, when the terminal enables the DRX function, the calculation of the first channel busy ratio satisfies the ratio of the number of first resources whose measurement results in the first time window are greater than the first threshold value to the number of all resources in the fifth time window.

[0122] Optionally, the first channel busy ratio may specifically be: a ratio of the number of first resources whose measurement results within the first time window are greater than a first threshold value to the number of all resources within the fifth time window.

[0123] It can be seen that since the calculation of the busy ratio of the first channel is based on the number of first resources whose measurement results within the first time window are greater than the first threshold value, and the number of all resources within the fifth time window, it is possible to avoid the situation where the calculation of the busy ratio of the first channel is inaccurate due to the DRX function being enabled by the terminal. In this way, the accuracy of the calculated busy ratio of the first channel can be improved.

[0124] A specific example is given below to illustrate how the terminal calculates the channel busy ratio according to the beam.

[0125] For example, in the related art, when the terminal evaluates the channel busy ratio in slot n, the terminal will calculate the channel busy ratio based on the measurement results in the first time window, that is, [n-100, n-1]. Assuming that there are 10 subchannels on each slot, there are 1000 subchannels in the first time window. If the number of first resources (such as subchannels) whose measurement results (such as RSSI) in the first time window are greater than the first threshold value is 450, then the channel busy ratio evaluated at this time is 450 / 1000=0.45. However, when the terminal in the resource pool measures, detects and sends based on the beam, since the beam has directionality, if the measurement results on all beams are still used to calculate the channel busy ratio, it may cause deviations in the evaluation of the system congestion situation. For example, the resource transmission situation detected by the north-facing beam of the terminal will not affect the terminal located on the east side of the terminal or the impact is very small, so it cannot represent the congestion situation on the east side of the terminal. Therefore, it is possible to consider using a beam-based channel busy ratio calculation method.

[0126] In the embodiments of the present application, Figure 3 As shown, it is assumed that beam 1 and beam 2 have performed measurements in the first time window, that is, time window 1 associated with beam 1 and time window 2 associated with beam 2. When the terminal decides to use beam 1 to send a corresponding beam for transmission, the first channel busy ratio can be calculated using the measurement result of beam 1. At this time, it is assumed that the number of first resources (such as subchannels) whose measurement results (such as RSSI) in beam 1 in the first time window are greater than the first threshold value is 300. At this time, there are the following methods for calculating the first channel busy ratio.

[0127] One method is 300 / 1000, that is, the range for evaluating the busy ratio of the first channel is still the first time window, but because there is a time window 2 associated with beam 2 in the first time window, and because beam 2 and beam 1 do not affect each other, only the measurement result corresponding to beam 1 is calculated. It can be understood that the method corresponds to the calculation of the busy ratio of the first channel, which satisfies the ratio of the number of first resources whose measurement results in the first time window are greater than the first threshold value relative to the number of all resources in the first time window.

[0128] Another method is 300 / 700, that is, the range of evaluating the busy ratio of the first channel at this time is the third time window corresponding to the measurement of beam 1 in the first time window, that is, the range of time window 1 associated with beam 1. Because there is a time window 2 corresponding to the association of beam 2 in the first time window at this time, and because beam 2 and beam 1 do not affect each other, only the system congestion within the range of time window 1 associated with beam 1 is calculated. It can be understood that the method corresponds to the calculation of the busy ratio of the first channel, which satisfies the ratio of the number of first resources whose measurement results in the first time window are greater than the first threshold value relative to the number of all resources in the third time window.

[0129] Another method is 400 / 1000. In this case, the 100 slots no longer correspond to the first time window, but the nearest 100 slots corresponding to beam 1 (i.e., the fourth time window), as shown in Figure 4, which is equivalent to the time window 1 associated with beam 1 in [n-130, n-1]. At this time, there may be not only 300 sub-channels with measurement results greater than the first threshold in these 100 slots, but 400, because the measurement results on 30 slots are calculated. It can be understood that this method corresponds to the calculation of the busy ratio of the first channel, which satisfies the ratio of the number of first resources whose measurement results in the first time window are greater than the first threshold value to the number of all resources in the fourth time window.

[0130] Another method is 600 / 1000. In this case, the scope for evaluating the busy ratio of the first channel is still the first time window. However, when calculating the busy ratio of the first channel, all subchannels in the time domain range other than beam 1 are considered to be occupied subchannels. It can be understood that this method corresponds to the calculation of the busy ratio of the first channel, which satisfies the ratio of the number of first resources whose measurement results in the first time window are greater than the first threshold value relative to the number of all resources in the first time window.

[0131] Of course, the terminal may also determine whether to calculate or determine the first channel busy ratio of the channel according to the beam according to whether a certain condition is met. Optionally, when a second condition is met (or an opposite condition of the second condition is not met), the terminal determines the first channel congestion parameter (e.g., the first channel busy ratio) based on the beam, and the second condition includes at least one of the following:

[0132] The second resource used by the terminal enables beam transmission, or does not enable omnidirectional beam transmission; it can be understood that, when beam transmission is enabled, other channel congestion parameters (in this solution, channel occupancy, channel occupancy limit value, etc.) or first channel congestion parameters (in this solution, first channel busy ratio) are selected to be calculated based on the beam; here, the other channel congestion parameters are channel congestion parameters different from the first channel congestion parameters;

[0133] The terminal calculates other channel congestion parameters (channel occupancy, channel occupancy limit value, etc. in this solution) based on the associated transmit beam;

[0134] The terminal is associated with at least two beams; it is understood that when the terminal is associated with more than one beam, the channel congestion parameter associated with the beam may be calculated instead of the channel congestion parameter associated with the terminal;

[0135] The receiving beam and transmitting beam associated with the terminal are reciprocal;

[0136] The width of the beam associated with the terminal is greater than the fifth threshold value, or less than the sixth threshold value; it can be understood that when the beam is wide enough (more measurement results) or narrow enough (little interference from other beams), the channel congestion parameters are calculated based on the beam, making the calculation results more accurate.

[0137] The duration of the terminal detecting the associated beam is greater than the duration of the first time window, or less than the duration of the first time window;

[0138] The higher layer indicates at least one beam to the terminal;

[0139] The higher layer indicates at least one third identifier to the terminal;

[0140] The high-level instructing terminal calculates other channel congestion parameters (in this solution, channel occupancy, channel occupancy limit value, etc.) or the first channel congestion parameter (in this solution, the first channel busy ratio) based on the associated transmit beam; it can be understood that the channel congestion parameters are calculated in the manner indicated by the high-level instructions.

[0141] The second resource used by the terminal is configured to calculate other channel congestion parameters (in this scheme, channel occupancy, channel occupancy limit value, etc.) or the first channel congestion parameter (in this scheme, the first channel busy ratio) based on the associated transmit beam; it can be understood that the configuration of the terminal tends to perform resource selection and transmission based on the beam, and therefore the channel congestion parameters are also calculated based on the beam.

[0142] The second resource used by the terminal is configured to perform detection according to the associated transmit beam;

[0143] The second resource used by the terminal is configured to perform resource selection according to the associated transmit beam;

[0144] The second resource used by the terminal is configured to be re-evaluated according to the associated transmit beam;

[0145] The second resource used by the terminal is configured with the priority of the associated transmission beam.

[0146] It should be noted that the above "opposite condition" can be understood as: a condition opposite to each requirement in the second condition. For example, assuming that the second condition is that the terminal is associated with at least two beams, the opposite condition of the second condition is that the terminal is associated with one beam, or the terminal is not associated with any beam.

[0147] In the embodiment of the present application, the third identifier is an identifier of another terminal.

[0148] Optionally, when the first channel congestion parameter includes a first channel busy ratio, the terminal determines the first channel busy ratio corresponding to each of at least some of the associated beams based on the beam; when the first channel congestion parameter includes a first channel occupancy limit value, the terminal determines the first channel occupancy limit value corresponding to each of at least some of the associated beams based on the first channel busy ratio corresponding to the beam.

[0149] It can be understood that if the terminal calculates the channel occupancy and / or channel occupancy limit value corresponding to the transmitting beam based on the associated transmitting beam, the terminal will also calculate the first channel occupancy limit value corresponding to a certain transmitting beam based on the transmitting beam used for signal transmission.

[0150] Optionally, the second resource may specifically be the resource pool.

[0151] Solution 2: Calculate the channel busy ratio based on all beams associated with the terminal

[0152] In this scheme, all beams associated with the terminal correspond to a channel busy ratio. The terminal calculates the channel busy ratio according to the resources corresponding to all beams, that is, calculates the channel busy ratio corresponding to a certain transmitting beam used by the terminal for signal transmission (that is, the first channel busy ratio).

[0153] In some embodiments of the present application, the first channel busy ratio is determined according to the number of first resources whose measurement results in the first time window are greater than the first threshold value. Wherein, in the case where the first resources include resources associated with the terminal, each resource associated with the terminal corresponds to a first threshold value, and different resources correspond to different first threshold values.

[0154] It can be understood that compared with the related art, in this scheme, the influence of the beam direction factor is taken into account, so the first threshold value corresponding to each resource associated with the terminal is different, instead of being determined according to the same threshold value. Therefore, the accuracy of the calculated first channel busy ratio can be improved.

[0155] In some embodiments of the present application, the calculation of the first channel busy ratio satisfies:

[0156] The ratio of the number of first resources whose measurement results within the first time window are greater than the first threshold to the number of all resources within the first time window.

[0157] Optionally, when the calculation of the first channel busy ratio satisfies the ratio of the number of first resources whose measurement results within the first time window are greater than the first threshold value to the number of all resources within the first time window, the first channel busy ratio may specifically be: the ratio of the number of first resources whose measurement results within the first time window are greater than the first threshold value to the number of all resources within the first time window.

[0158] Thus, it can be known that since the calculation of the first channel busy ratio is based on the number of first resources whose measurement results in the first time window are greater than the first threshold value and the number of all resources in the first time window. Further, the first threshold values ​​corresponding to the first resources can be different, that is, not determined by the same threshold value, for example, the threshold values ​​corresponding to the first resources associated with different beams are different. Therefore, the accuracy of the calculated first channel busy ratio can be improved.

[0159] Solution 3: Calculate channel busy ratio by beam group

[0160] In this solution, the terminal can calculate the channel busy ratio (ie, the first channel busy ratio) corresponding to a certain transmission beam used by the terminal for signal transmission according to the above-mentioned first beam group.

[0161] It should be noted that, for the specific method of calculating the busy ratio of the first channel according to the beam group, reference may be made to the specific description in Solution 1 in the above embodiment, and the embodiments of the present application will not be repeated here.

[0162] Solution 4: Determine the channel busy ratio according to the default parameters

[0163] In this solution, the terminal can determine the channel busy ratio (ie, the first channel busy ratio) corresponding to a certain transmission beam used by the terminal for signal transmission according to the above default parameters.

[0164] In some embodiments of the present application, when the first channel busy ratio is determined according to a default parameter, the default parameter satisfies at least one of the following:

[0165] is determined based on the first object;

[0166] It is determined according to the first object and at least one corresponding relationship.

[0167] Optionally, when the default parameter is determined according to the first object, the default parameter corresponding to the first object can be preconfigured, so that the terminal can directly determine the default parameter according to the first object, and determine the default parameter as the first channel busy ratio.

[0168] In the embodiment of the present application, the above correspondence is a correspondence between an object and a parameter. For example, the index order of the first object corresponds to a specific parameter in a parameter set.

[0169] Optionally, the terminal may obtain a default CBR list, and determine the default parameter corresponding to the first object from the set according to different corresponding relationships. The default CBR list includes at least one of the above corresponding relationships. The default CBR list may be predefined by the protocol, preconfigured by the network side device, configured by the network side device, or determined by the terminal.

[0170] Among them, in at least one corresponding relationship in the default CBR list, different objects (such as different receiving beams, transmitting beams, etc.) correspond to different parameters.

[0171] Optionally, when the default parameter is determined based on the first object and at least one corresponding relationship, the terminal may determine a default parameter corresponding to the first object from at least one object in the at least one corresponding relationship, and determine it as the first channel busy ratio.

[0172] Thus, it can be seen that, since the embodiment of the present application specifies a specific scheme for how the terminal calculates the busy ratio of the first channel according to the default parameters, it is possible to avoid the situation where the terminal cannot calculate the busy ratio of the first channel.

[0173] A specific example will be used below to illustrate how the terminal determines the busy ratio of the first channel according to the default parameters.

[0174] For example, when calculating the busy ratio of the first channel based on the beam direction, there may be a problem that there is no measurement result corresponding to the subsequent beam in the busy ratio of the first channel evaluated in slot n. One possibility is that due to the configuration of DRX, the first time window may correspond to the drx off state, resulting in fewer measurement results in the first time window. Another possibility is that due to the configuration or change of the beam corresponding to the time, when the terminal uses beam 1 to send, most of the slots in the first 100 slots belong to the time windows corresponding to other beams, resulting in fewer measurement results corresponding to beam 1 in the first time window. After the above situation occurs, you can consider using the default parameters as the final determined first channel busy ratio to avoid excessive deviation in the evaluated first channel busy ratio value.

[0175] Of course, the terminal can also determine which specific solution to adopt to calculate or determine the first channel busy ratio according to whether a certain condition is met. Optionally, when the first condition is not met (or the opposite condition of the first condition is met), the first channel busy ratio is determined according to the number of first resources whose measurement results within the first time window are greater than the first threshold value; or, when the first condition is met (or the opposite condition of the first condition is not met), the first channel busy ratio is determined according to default parameters.

[0176] In the embodiment of the present application, the first condition includes at least one of the following:

[0177] The number of time units within the third time window is less than the second threshold value;

[0178] The number of measurement results of all resources within the first time window is less than a third threshold value;

[0179] The number of measurement results of the resources associated with the first object within the first time window is less than a fourth threshold value;

[0180] When selecting a carrier, the terminal determines whether to select or not select the first carrier.

[0181] In the embodiment of the present application, the third time window is: a time window associated with the first object in the first time window.

[0182] It should be noted that, for the description of the third time window, reference may be made to the specific description in the above embodiment, and the embodiments of the present application will not be repeated here.

[0183] In an embodiment of the present application, if the first condition is not met, that is, if the number of time units within the third time window is greater than or equal to the second threshold value, and / or the number of measurement results of all resources within the first time window is greater than or equal to the third threshold value, and / or the number of measurement results of resources associated with the first object within the first time window is greater than or equal to the fourth threshold value, then it can be considered that the number of first resources that can be used to calculate the first channel busy ratio is sufficient. Therefore, the terminal can determine the first channel busy ratio based on the number of first resources whose measurement results within the first time window are greater than the first threshold value.

[0184] In an embodiment of the present application, if the number of time units within the third time window is less than the second threshold value, and / or the number of measurement results of all resources within the first time window is less than the third threshold value, and / or the number of measurement results of resources associated with the first object within the first time window is less than the fourth threshold value, then it can be considered that the number of first resources that can be used to calculate the first channel busy ratio is too small, and therefore, the terminal can calculate the default parameters or use the default parameters to determine the first channel busy ratio.

[0185] In some embodiments of the present application, the first carrier may specifically be a specific carrier, for example, a predefined carrier, a preconfigured carrier, a configured carrier, etc.

[0186] Exemplarily, when there is ongoing transmission on a certain carrier (i.e., the first carrier), in order not to select this carrier for other transmission, the default parameter is selected as the first channel busy ratio of this carrier. It can be understood that the CBR value configured by the default parameter is relatively large at this time, and the default parameter is used as the first channel busy ratio of this carrier, and the terminal will be less likely to select this carrier for transmission.

[0187] As another example, the terminal selects or returns to a certain carrier (i.e., the first carrier) for transmission, and selects the default parameter as the first channel busy ratio of this carrier. It can be understood that the CBR value configured by the default parameter is small at this time, and the terminal will be more likely to select this carrier for transmission by using the default parameter as the first channel busy ratio of this carrier.

[0188] Example 2: The first channel congestion parameter includes the first channel occupancy rate CR

[0189] In the related art, the CR calculation mechanism of SL is based on the background that the terminal performs omnidirectional detection in the FR1 frequency band. When the terminal works in the FR2 frequency band, due to the directionality of the beam, the terminal's perception of channel congestion and channel occupancy are both directional. At this time, the existing CR calculation method may no longer be accurate, thereby affecting subsequent resource allocation.

[0190] In order to solve the above technical problem, in some embodiments of the present application, the above first channel congestion parameter includes a first channel occupancy rate, and the first channel occupancy rate is determined according to the following:

[0191] The number of first transmission resources within the second time window.

[0192] Solution 5: Calculate channel occupancy by beam

[0193] In this solution, calculating the channel occupancy rate according to the beam can be understood as calculating the relevant channel occupancy rate based on a specific beam, such as a transmitting beam, that is, calculating the channel occupancy rate based on the resources associated with the first object, or calculating the channel occupancy rate for each beam of at least part of the associated beams, for example, each beam corresponds to a channel occupancy rate, and the terminal calculates the channel occupancy rate corresponding to each beam according to the transmission resources corresponding to each beam. It can be understood that compared with the relevant technology, in this solution, each channel occupancy rate takes into account the factor of the beam direction, rather than being performed according to the background of omnidirectional detection, so the accuracy of the calculated channel occupancy rate can be improved.

[0194] The following will take the calculation of the channel occupancy rate (ie, the first channel occupancy rate) corresponding to a certain transmission beam used by the terminal for signal transmission as an example for explanation.

[0195] In some embodiments of the present application, when the first resource is a transmission resource associated with the first object, the calculation of the first channel occupancy rate satisfies at least one of the following:

[0196] The ratio of the number of first transmission resources in the second time window to the number of transmission resources in the second time window.

[0197] Optionally, when the calculation of the first channel occupancy rate satisfies the ratio of the number of first transmission resources in the second time window to the number of transmission resources in the second time window, the first channel occupancy rate may specifically be: the ratio of the number of first transmission resources in the second time window to the number of transmission resources in the second time window.

[0198] Of course, the terminal may also determine whether to calculate or determine the first channel occupancy rate of the channel according to the beam according to whether a certain condition is met. Optionally, when a second condition is met (or an opposite condition of the second condition is not met), the terminal determines the first channel congestion parameter (e.g., the first channel occupancy rate) based on the beam, and the second condition includes at least one of the following:

[0199] The second resource used by the terminal enables beam transmission, or does not enable omnidirectional beam transmission; it can be understood that, when beam transmission is enabled, other channel congestion parameters (in this solution, channel busy ratio, channel occupancy limit value, etc.) or first channel congestion parameters (in this solution, first channel occupancy) are selected based on beam calculation; here, the other channel congestion parameters are channel congestion parameters different from the first channel congestion parameters;

[0200] The terminal calculates other channel congestion parameters (i.e., channel busy ratio, channel occupancy limit value, etc. in this solution) based on the associated transmit beam;

[0201] The terminal is associated with at least two beams; it is understood that when the terminal is associated with more than one beam, the channel congestion parameter associated with the beam may be calculated instead of the channel congestion parameter associated with the terminal;

[0202] The receiving beam and transmitting beam associated with the terminal are reciprocal;

[0203] The width of the beam associated with the terminal is greater than the fifth threshold value, or less than the sixth threshold value; it can be understood that when the beam is wide enough (more measurement results) or narrow enough (little interference from other beams), the channel congestion parameters are calculated based on the beam, making the calculation results more accurate.

[0204] The duration of the terminal detecting the associated beam is greater than the duration of the first time window, or less than the duration of the first time window;

[0205] The higher layer indicates at least one beam to the terminal;

[0206] The higher layer indicates at least one third identifier to the terminal;

[0207] The high-level instructing terminal calculates other channel congestion parameters (in this solution, the channel busy ratio, channel occupancy limit value, etc.) or the first channel congestion parameter (in this solution, the first channel occupancy) based on the associated transmit beam; it can be understood that the channel congestion parameters are calculated in the manner indicated by the high-level instructions.

[0208] The second resource used by the terminal is configured to calculate other channel congestion parameters (in this scheme, the channel busy ratio, channel occupancy limit value, etc.) or the first channel congestion parameter (in this scheme, the first channel occupancy) based on the associated transmit beam; it can be understood that the configuration of the terminal tends to perform resource selection and transmission based on the beam, and therefore the channel congestion parameters are also calculated based on the beam.

[0209] The second resource used by the terminal is configured to perform detection according to the associated transmit beam;

[0210] The second resource used by the terminal is configured to perform resource selection according to the associated transmit beam;

[0211] The second resource used by the terminal is configured to be re-evaluated according to the associated transmit beam;

[0212] The second resource used by the terminal is configured with the priority of the associated transmission beam.

[0213] In the embodiment of the present application, the third identifier is an identifier of another terminal.

[0214] Optionally, when the first channel congestion parameter includes a first channel busy ratio, the terminal determines the first channel busy ratio corresponding to each of at least some of the associated beams based on the beam; when the first channel congestion parameter includes a first channel occupancy limit value, the terminal determines the first channel occupancy limit value corresponding to each of at least some of the associated beams based on the first channel busy ratio corresponding to the beam.

[0215] It can be understood that if the terminal calculates the channel busy ratio and / or channel occupancy limit value corresponding to the transmitting beam based on the associated transmitting beam, the terminal will also calculate the first channel occupancy limit value corresponding to a certain transmitting beam based on the transmitting beam used for signal transmission.

[0216] Optionally, the second resource may specifically be the resource pool.

[0217] Solution 6: Calculate channel occupancy based on all beams associated with the terminal

[0218] In this scheme, all beams associated with the terminal correspond to a channel occupancy rate, and the terminal calculates the channel occupancy rate according to the transmission resources corresponding to all beams, that is, calculates the channel occupancy rate (that is, the first channel occupancy rate) corresponding to a certain transmitting beam used by the terminal for signal transmission.

[0219] In some embodiments of the present application, when the first resource is all transmission resources associated with the terminal, the calculation of the first channel occupancy rate satisfies at least one of the following:

[0220] The ratio of the number of first transmission resources in the second time window to the number of transmission resources in the second time window.

[0221] Solution 7: Calculate channel occupancy by beam group

[0222] In this solution, in this solution, the terminal can calculate the channel occupancy rate (ie, the first channel occupancy rate) corresponding to a certain transmission beam used by the terminal for signal transmission according to the above-mentioned first beam group.

[0223] It should be noted that, for the specific method of calculating the first channel occupancy rate according to the first beam group, reference may be made to the specific description in Scheme 5 in the above embodiment, and the embodiments of the present application will not be repeated here.

[0224] Of course, the terminal may also determine which specific solution to adopt to calculate the first channel occupancy rate according to whether a certain condition is met. Optionally, when the fourth condition is met (or the opposite condition of the fourth condition is not met), the first transmission resource includes the transmission resource associated with the first object; wherein the fourth condition includes at least one of the following:

[0225] The terminal calculates other channel congestion parameters (i.e., channel busy ratio, channel occupancy limit value, etc. in this solution) based on the associated transmit beam;

[0238] It can be understood that if the terminal calculates the channel busy ratio and / or channel occupancy limit value corresponding to the transmission beam based on the associated transmission beam, the terminal will also calculate the first channel occupancy corresponding to the transmission beam based on the transmission beam used for signal transmission.

[0239] Optionally, the second resource may specifically be the resource pool.

[0240] In the embodiment of the present application, the third identifier is an identifier of another terminal.

[0241] Example 3: The first channel congestion parameter includes a first channel occupancy rate limit value CR limit

[0242] In some embodiments of the present application, the first channel congestion parameter includes a first channel busy ratio and a first channel occupancy rate limit value; the first channel occupancy rate limit value is determined according to at least one of the following:

[0243] First channel busy ratio;

[0244] The channel busy ratio corresponding to all transmit beams associated with the terminal.

[0245] It should be noted that, in this example, the first channel busy ratio may be calculated according to the solution in Example 1, or calculated according to a solution in the related art, and the embodiment of the present application does not limit this.

[0246] Solution 8: Calculate channel occupancy limit value according to beam

[0247] In the present solution, calculating the channel occupancy limit value according to the beam can be understood as calculating the relevant occupancy limit value based on a specific beam, such as a transmitting beam, that is, calculating the occupancy limit value based on the resources associated with the first object, or calculating the occupancy limit value for each beam of at least part of the associated beams. For example, each beam corresponds to a channel occupancy limit value, and the terminal calculates the channel occupancy limit value corresponding to each beam according to the resources corresponding to each beam. It can be understood that compared with the relevant technology, in the present solution, each channel occupancy limit value takes into account the factor of the beam direction, rather than being executed according to the background of omnidirectional detection. Therefore, the accuracy of the calculated channel occupancy limit value can be improved.

[0248] The following will take the calculation of the channel occupancy rate limit value (ie, the first channel occupancy rate limit value) corresponding to a certain transmission beam used by the terminal for signal transmission as an example for explanation.

[0249] Optionally, when the first channel occupancy rate limit value is determined based on the first channel busy ratio, the first channel occupancy rate limit value may specifically be: the channel occupancy rate limit value corresponding to the first channel busy ratio, or calculated based on the channel occupancy rate limit value corresponding to the first channel busy ratio and an offset value.

[0250] The first channel occupancy rate limit value is determined by the channel occupancy rate limit value corresponding to the first channel busy ratio and the first offset value; the first offset value satisfies any of the following: related to the proportion of the third time window relative to the first time window, predefined by the protocol, preconfigured by the network side device, configured by the network side device, or determined by the terminal. The third time window is: the third time window is: the time window associated with the first object in the first time window.

[0251] Of course, the terminal may also determine whether to calculate the first channel occupancy limit value according to the beam according to whether a certain condition is met. Optionally, when a second condition is met (or an opposite condition of the second condition is not met), the terminal determines the first channel congestion parameter (for example, the first occupancy limit value) based on the beam, and the second condition includes at least one of the following:

[0252] The second resource used by the terminal enables beam transmission, or does not enable omnidirectional beam transmission; it can be understood that, when beam transmission is enabled, other channel congestion parameters (i.e., channel busy ratio, channel occupancy rate, etc. in this solution) or first channel congestion parameters (i.e., first channel occupancy rate limit value in this solution) are selected to be calculated based on the beam; here, the other channel congestion parameters are channel congestion parameters different from the first channel congestion parameters;

[0253] The terminal calculates other channel congestion parameters (channel busy ratio, channel occupancy rate, etc. in this solution) based on the associated transmit beam;

[0254] The terminal is associated with at least two beams; it is understood that when the terminal is associated with more than one beam, the channel congestion parameter associated with the beam may be calculated instead of the channel congestion parameter associated with the terminal;

[0255] The receiving beam and transmitting beam associated with the terminal are reciprocal;

[0256] The width of the beam associated with the terminal is greater than the fifth threshold value, or less than the sixth threshold value; it can be understood that when the beam is wide enough (more measurement results) or narrow enough (little interference from other beams), the channel congestion parameters are calculated based on the beam, making the calculation results more accurate.

[0257] The duration of the terminal detecting the associated beam is greater than the duration of the first time window, or less than the duration of the first time window;

[0258] The higher layer indicates at least one beam to the terminal;

[0259] The higher layer indicates at least one third identifier to the terminal;

[0260] The high-level instructing terminal calculates other channel congestion parameters (in this solution, the channel busy ratio, channel occupancy rate, etc.) or the first channel congestion parameter (in this solution, the first channel occupancy rate limit value) based on the associated transmit beam; it can be understood that the channel congestion parameters are calculated in the manner indicated by the high-level instructions.

[0261] The second resource used by the terminal is configured to calculate other channel congestion parameters (in this scheme, the channel busy ratio, channel occupancy rate, etc.) or the first channel congestion parameter (in this scheme, the first channel occupancy rate limit value) based on the associated transmit beam; it can be understood that the configuration of the terminal tends to perform resource selection and transmission based on the beam, and therefore the channel congestion parameters are also calculated based on the beam.

[0262] The second resource used by the terminal is configured to perform detection according to the associated transmit beam;

[0263] The second resource used by the terminal is configured to perform resource selection according to the associated transmit beam;

[0264] The second resource used by the terminal is configured to be re-evaluated according to the associated transmit beam;

[0265] The second resource used by the terminal is configured with the priority of the associated transmission beam.

[0266] In the embodiment of the present application, the third identifier is an identifier of another terminal.

[0267] Optionally, when the first channel congestion parameter includes a first channel busy ratio, the terminal determines the first channel busy ratio corresponding to each of at least some of the associated beams based on the beam; when the first channel congestion parameter includes a first channel occupancy limit value, the terminal determines the first channel occupancy limit value corresponding to each of at least some of the associated beams based on the first channel busy ratio corresponding to the beam.

[0268] It can be understood that if the terminal calculates the channel busy ratio and / or channel occupancy rate corresponding to the transmission beam based on the associated transmission beam, the terminal will also calculate the first channel occupancy rate limit value corresponding to a certain transmission beam based on the transmission beam used for signal transmission.

[0269] Optionally, the second resource may specifically be the resource pool.

[0270] Optionally, when the terminal selects a carrier, in a case where the terminal determines to select or not select the first carrier, the terminal may also determine the first channel busy ratio or the first channel occupancy rate limit value according to the above default parameters.

[0271] In some embodiments of the present application, the first carrier may specifically be a specific carrier, for example, a predefined carrier, a preconfigured carrier, a configured carrier, etc.

[0272] Exemplarily, when there is ongoing transmission on a certain carrier (ie, the first carrier), in order not to select this carrier for other transmissions, a default parameter is selected as the first channel busy ratio or the first channel occupancy rate limit value of this carrier.

[0273] As another example, the terminal selects or returns to a certain carrier (ie, the first carrier) for transmission, and selects a default parameter as the first channel busy ratio or the first channel occupancy rate limit value of the carrier.

[0274] Solution 9: Calculate the channel occupancy limit value according to all beams associated with the terminal

[0275] In this scheme, all beams associated with the terminal correspond to a channel occupancy rate limit value, and the terminal calculates the channel occupancy rate limit value (i.e., the first channel occupancy rate limit value) corresponding to all beams by using the channel busy ratio (i.e., the first channel busy ratio) corresponding to all beams.

[0276] Of course, the terminal may also determine whether to adopt solution 9 to determine the first channel occupancy rate limit value according to whether a certain condition is met. Optionally, when the third condition is met (or the opposite condition of the third condition is not met), the first channel occupancy rate limit value is determined according to the channel busy ratio corresponding to all transmit beams associated with the terminal, and the third condition includes at least one of the following:

[0277] The terminal calculates other channel congestion parameters (channel busy ratio, channel occupancy rate, etc. in this solution) based on all associated transmit beams;

[0278] The period of the beam scanning of the terminal is less than the seventh threshold value;

[0279] The terminal is performing carrier selection;

[0280] The terminal is performing beam switching;

[0281] The second resource used by the terminal enables omni-directional beam transmission;

[0282] The second resource used by the terminal enables omni-directional beam reception;

[0283] The second resource used by the terminal does not enable beam transmission;

[0284] The second resource used by the terminal does not enable beam reception;

[0285] The terminal is associated with at least one beam;

[0286] The higher layer indicates at least one third identifier to the terminal;

[0287] The high-layer instructs the terminal to calculate other channel congestion parameters (i.e., channel busy ratio, channel occupancy rate, etc. in this solution) or the first channel congestion parameter (i.e., the first channel occupancy rate limit value in this solution) based on all associated transmit beams;

[0288] The second resource used by the terminal is configured to calculate other channel congestion parameters (i.e., channel busy ratio, channel occupancy rate, etc. in this solution) or the first channel congestion parameter (i.e., the first channel occupancy rate limit value in this solution) based on all associated transmit beams;

[0289] The second resource used by the terminal is configured to perform detection according to all associated transmit beams;

[0290] The second resource used by the terminal has been configured to perform resource selection according to all associated transmit beams;

[0291] The second resource used by the terminal has been configured to be re-evaluated according to all associated transmit beams;

[0292] The second resource used by the terminal has been configured with the priorities of all associated transmit beams.

[0293] It can be understood that if the terminal calculates the channel busy ratio and / or channel occupancy rate corresponding to all transmitting beams based on all associated transmitting beams, then all transmitting beams correspond to the same channel congestion parameter. Therefore, it can be understood that the terminal will also calculate the channel occupancy limit value (i.e., the first channel occupancy limit value) corresponding to a certain transmitting beam used for signal transmission based on all associated transmitting beams.

[0294] Optionally, the second resource may specifically be the resource pool.

[0295] In the embodiment of the present application, the third identifier is an identifier of another terminal.

[0296] Of course, after calculating and obtaining the first channel occupancy rate limit value, the terminal may also determine whether to perform data transmission according to the calculated first channel occupancy rate limit value, which will be described below with an example.

[0297] In some embodiments of the present application, the first channel congestion parameter includes a first channel occupancy rate limit value; the first channel occupancy rate limit value satisfies at least one of the following:

[0298] It is determined by the terminal based on the associated transmit beam;

[0299] It is determined by the terminal based on all associated transmit beams.

[0300] It should be noted that for the method of determining the transmission beam based on the association of the terminal, reference can be made to the specific description in the above embodiment, and the embodiment of the present application will not be repeated here. For the method of determining the transmission beam based on all the associations of the terminal, reference can be made to the specific description in the above embodiment, and the embodiment of the present application will not be repeated here.

[0301] In some embodiments of the present application, the first channel occupancy rate limit value is determined by the terminal based on the associated transmit beam, and the first channel congestion parameter further includes the first channel occupancy rate. Figure 2 ,like Figure 4 As shown, after the above step 101, the channel congestion parameter determination method provided in the embodiment of the present application may further include the following step 201.

[0302] Step 201: When the occupancy rate of a first channel is less than a limit value of the occupancy rate of a first channel, the terminal performs data transmission.

[0303] In some embodiments of the present application, when the first channel occupancy rate is less than the first channel occupancy rate limit value, the terminal may transmit data according to a certain transmitting beam used for signal transmission (for example, the first beam, or a transmitting beam corresponding to the first beam), or may transmit based on the resources associated with the above-mentioned first object.

[0304] As can be seen, since the terminal performs data transmission only when the first channel occupancy rate is less than the first channel occupancy rate limit value, it is possible to avoid the terminal occupying too many resources, thereby improving resource utilization.

[0305] In some embodiments of the present application, the first channel occupancy rate limit value is determined by the terminal based on all associated transmit beams, and the first channel congestion parameter also includes the first channel occupancy rate. Optionally, after the above step 101, the channel congestion parameter determination method provided in the embodiment of the present application may also include the following step 301 or step 302.

[0306] Step 301: When the occupancy rate of a first channel is less than a second channel occupancy limit value, the terminal performs data transmission.

[0307] In the embodiment of the present application, the second channel occupancy limit value is determined according to the first channel occupancy rate limit value and the number of all beams associated with the terminal.

[0308] In some embodiments of the present application, the second channel occupancy limit value may specifically be: the first channel occupancy rate limit value divided by the number of some or all beams associated with the terminal.

[0309] It can be understood that the channel occupancy limit value on each beam is equal, and the terminal can compare the channel occupancy calculated on each beam with the second channel occupancy limit value on the beam to determine whether to transmit data.

[0310] In some embodiments of the present application, when the occupancy rate of the first channel is less than the occupancy limit value of the second channel, the terminal may transmit data according to a certain transmitting beam used for signal transmission (for example, the first beam, or a transmitting beam corresponding to the first beam), or may transmit based on the resources associated with the above-mentioned first object.

[0311] As can be seen, since the terminal performs data transmission only when the first channel occupancy rate is less than the second channel occupancy limit value, it is possible to avoid the terminal occupying too many resources, thereby improving resource utilization.

[0312] Step 302: When the occupancy rate of the second channel is less than the limit value of the occupancy rate of the first channel, the terminal performs data transmission.

[0313] In the embodiment of the present application, the second channel occupancy rate is determined according to the channel occupancies corresponding to all beams associated with the terminal.

[0314] In some embodiments of the present application, the second channel occupancy rate may specifically be: the sum of channel occupancies corresponding to some or all beams associated with the terminal.

[0315] It can be understood that the terminal can calculate a corresponding channel occupancy rate according to all beams associated with the terminal, and finally add up the sum of the channel occupancies, and compare it with the first channel occupancy rate limit value to determine whether data transmission can be performed.

[0316] In some embodiments of the present application, when the second channel occupancy rate is less than the first channel occupancy rate limit value, the terminal may transmit data according to a certain transmitting beam used for signal transmission (for example, the first beam, or a transmitting beam corresponding to the first beam), or may transmit based on the resources associated with the above-mentioned first object.

[0317] As can be seen, since the terminal performs data transmission only when the occupancy rate of the second channel is less than the limit value of the occupancy rate of the first channel, it is possible to avoid the terminal occupying too many resources, thereby improving the utilization rate of resources.

[0318] The channel congestion parameter determination method provided in the embodiment of the present application may be executed by a channel congestion parameter determination device. In the embodiment of the present application, the channel congestion parameter determination device executing the channel congestion parameter determination method is taken as an example to illustrate the channel congestion parameter determination device provided in the embodiment of the present application.

The first resource includes at least one of the following: resources associated with the first object, resources associated with the channel congestion parameter determination device 50; the first transmission resource includes at least one of the following: transmission resources associated with the first object, all transmission resources associated with the channel congestion parameter determination device 50.

Therefore, it can be avoided that the channel congestion parameter determination device cannot perform signal transmission. In this way, the transmission reliability of the channel congestion parameter determination device can be improved.
