[0002] This application claims priority to Chinese Patent Application No. 201910736176.6, filed in China on August 9, 2019, the entire contents of which are incorporated herein by reference. Technical Field

[0003] This disclosure relates to the field of mobile communication technology, and in particular to a method, apparatus, device and medium for transmitting feedback information. Background Technology

[0004] New Radio (NR) vehicle-to-X (V2X) supports hybrid automatic repeat request (HARQ) via sidelink (SL). This HARQ is carried on either the physical sidelink shared channel (PSSCH) or the physical sidelink control channel (PSCCH). Upon receiving the HARQ transmitted on the PSSCH or PSCCH, the terminal device will send corresponding feedback information, which is carried on the physical sidelink feedback channel (PSFCH).

[0005] SL supports unicast, multicast, and broadcast. For multicast transmission, there are two feedback methods: the first feedback method is that all receivers share the PSFCH resource and only send back unacknowledged responses; the second feedback method is that receivers occupy different PSFCH resources and send back acknowledgment or unacknowledged responses on their respective PSFCH resources.

[0024] To make the inventive objectives, technical solutions, and beneficial technical effects of this disclosure clearer, the following detailed description is provided in conjunction with specific embodiments. It should be understood that the embodiments described in this specification are merely illustrative and not intended to limit the scope of this disclosure.

[0025] For simplicity, this paper only explicitly discloses some numerical ranges. However, any lower limit can be combined with any upper limit to form an undefined range; and any lower limit can be combined with other lower limits to form an undefined range, just as any upper limit can be combined with any other upper limit to form an undefined range. Furthermore, although not explicitly stated, every point or individual value between the endpoints of a range is included within that range. Therefore, each point or individual value can serve as its own lower or upper limit and be combined with any other point or individual value, or with other lower or upper limits, to form an undefined range.

[0026] In the description of this article, it should be noted that, unless otherwise stated, "above" and "below" include the number itself, and "several" in "one or several" means two or more.

[0027] The foregoing description of this invention is not intended to describe every disclosed embodiment or implementation. Instead, the following description provides more specific examples of exemplary embodiments. Throughout the application, guidance is provided through a series of embodiments that can be used in various combinations. The examples listed are merely representative and should not be construed as exhaustive.

[0028] This disclosure provides a feedback information transmission method, apparatus, device, and medium. The feedback information transmission method provided in this disclosure will be described first.

[0029] The feedback information transmission method provided in this disclosure can be applied to terminal devices that transmit data via physical sidelink channels. For example, it can receive HARQ via PSSCH or PSCCH and send back feedback information corresponding to the HARQ via PSFCH.

[0030] Figure 1 illustrates a first flowchart of the feedback information transmission method provided in this embodiment of the present disclosure. The feedback information transmission method may include:

[0031] S101: Receive at least one transmission information transmitted on at least one physical sidelink channel.

[0032] In this process, one transmission message is transmitted on each physical side link channel.

[0033] In one embodiment of this disclosure, the physical sidelink channel may include: PSSCH and / or PSCCH.

[0034] For example, at least one physical sidelink channel has 3 channels. All three physical sidelink channels can be PSSCH; all three physical sidelink channels can also be PSCCH; the three physical sidelink channels can also be: 1 PSSCH and 2 PSCCH; or the three physical sidelink channels can also be: 2 PSSCH and 1 PSCCH.

[0035] In other words, at least one physical sidelink channel in the embodiments of this disclosure can be all PSSCH, all PSCCH, or a combination of PSSCH and PSCCH.

[0036] The transmission information transmitted on each physical sidelink channel in this embodiment refers to the data transmitted on that physical sidelink channel.

[0037] S102: Determine the power information corresponding to each of the at least one feedback information corresponding to at least one transmission information.

[0038] In one embodiment of this disclosure, the power information corresponding to the feedback information refers to the power information of the PSFCH resource that carries the feedback information.

[0039] S103: Based on the power information corresponding to each feedback information, transmit the corresponding feedback information on at least one PSFCH resource.

[0040] In one embodiment of this disclosure, the power information may be the transmit power, the transmit power spectrum, or the power spectrum density (PSD).

[0041] The feedback information transmission method of this disclosure determines the power information corresponding to each of the at least one feedback information corresponding to at least one transmission information; and transmits the corresponding feedback information on at least one PSFCH resource according to the power information corresponding to each feedback information, thereby enabling the transmission of the corresponding feedback information according to the power information corresponding to each feedback information.

[0042] The following explanation uses the transmission power as an example.

[0043] In one embodiment of this disclosure, the transmission power corresponding to each feedback message can be determined to be a preset transmission power.

[0044] For example, suppose the preset transmit power is 1 watt (W). Then the transmit power corresponding to each feedback message is determined to be 1W.

[0045] In one embodiment of this disclosure, the transmit power corresponding to each feedback information can be determined to be the arithmetic average of the overall transmit power with respect to the number of feedback information.

[0046] For example, assuming there are 10 feedback messages and the overall transmission power is 20W, the arithmetic average of the overall transmission power is 20W / 10 = 2W. Therefore, the transmission power corresponding to each feedback message is determined to be 2W.

[0047] In one embodiment of this disclosure, the transmission power corresponding to each feedback information can be determined based on first attribute information. The first attribute information may include any one of the following: channel state information (SCI) of the monitoring link, reference signal received power (RSRP) of the monitoring link, distance to the device transmitting the aforementioned transmission information, and the location of the device transmitting the aforementioned transmission information.

[0048] For example, the distance to the device transmitting the aforementioned information will be used as an example for illustration.

[0049] Assume a predefined relationship between the distance to the device transmitting the aforementioned information and the corresponding transmission power of the feedback information. For example, if the distance to the device transmitting the aforementioned information is within 1 kilometer, the corresponding transmission power of the feedback information is x dBm; if the distance to the device transmitting the aforementioned information is within 1 to 2 kilometers, the corresponding transmission power of the feedback information is x + y dBm; if the distance to the device transmitting the aforementioned information is within 2 to 3 kilometers, the corresponding transmission power of the feedback information is x + 2y dBm; and so on. That is, for every increase in a certain distance range, the transmission power increases by y dBm.

[0050] After receiving the transmission information, the distance to the device transmitting the transmission information is determined, and then the transmission power corresponding to the feedback information is determined based on the correspondence between the distance to the device transmitting the transmission information and the transmission power corresponding to the feedback information.

[0051] In one embodiment of this disclosure, the transmission power corresponding to each feedback message can be determined based on the second attribute information of the transmission information. The second attribute information may include any one of the following: Quality of Service (QoS), priority, modulation and coding scheme (MCS), resource usage, and number of layers.

[0052] For example, let's take the priority of transmitting information as an example.

[0053] Assume that a predefined relationship exists between the priority of transmitted information and the transmission power of the feedback information. For example, the transmission power of the feedback information corresponding to the first priority transmitted information is x dBm; the transmission power of the feedback information corresponding to the second priority transmitted information is x+y dBm; the transmission power of the feedback information corresponding to the third priority transmitted information is x+2y dBm; and so on. That is, for each additional priority, the transmission power increases by y dBm.

[0054] After receiving the transmission information, the priority of the transmission information is determined, and then the transmission power corresponding to the feedback information is determined based on the correspondence between the priority of the transmission information and the transmission power corresponding to the feedback information.

[0055] In one embodiment of this disclosure, the transmission power corresponding to each feedback information can be determined based on the transmission method used to transmit the aforementioned transmission information. The transmission method may include: transmitting the aforementioned transmission information using a beam and transmitting the aforementioned transmission information without using a beam.

[0056] For example, suppose a predefined correspondence is established between the transmission method and the transmission power corresponding to the feedback information. For instance, the transmission power corresponding to the feedback information using beamforming is x dBm, and the transmission power corresponding to the feedback information not using beamforming is x+y dBm.

[0057] After receiving the transmitted information, determine whether beamforming was used to transmit the information. If beamforming was used, determine the transmission power of the feedback information corresponding to the transmitted information as x dBm; if beamforming was not used, determine the transmission power of the feedback information corresponding to the transmitted information as x+y dBm.

[0058] In one embodiment of this disclosure, the transmission power corresponding to each feedback information can be determined based on the transmission type of at least one transmission information.

[0059] The transmission types in this disclosure embodiment may include: unicast, multicast based on a first feedback method, and multicast based on a second feedback method. Specifically, for multicast based on the first feedback method, all receiving devices share PSFCH resources, and the receiving devices only send back non-acknowledgment (NACK) responses. For multicast based on the second feedback method, receiving devices occupy different PSFCH resources and send back acknowledgment (ACK) or NACK responses on their respective occupied PSFCH resources.

[0060] Assume that a predefined correspondence is established between the transmission type of the transmitted information and the transmission power of the feedback information. For example, the transmission power corresponding to unicast is x dBm; the transmission power corresponding to multicast based on the first feedback method is xy dBm; and the transmission power corresponding to multicast based on the second feedback method is x dBm.

[0061] After receiving the transmission information, the transmission type of the transmission information is determined, and then the transmission power corresponding to the feedback information is determined based on the correspondence between the transmission type of the transmission information and the transmission power corresponding to the feedback information.

[0062] In one embodiment of this disclosure, the transmission power corresponding to each feedback information can be determined based on the priority corresponding to the transmission type of at least one transmission information.

[0063] For example, the priority of unicast is higher than the priority of multicast based on the second feedback method, the priority of multicast based on the second feedback method is higher than the priority of multicast based on the first feedback method, the transmission power corresponding to the lowest priority is x dBm, and the transmission power difference between two adjacent priorities is y dBm.

[0064] After receiving the transmission information, the transmission type of the transmission information is determined, and then the transmission power corresponding to the feedback information corresponding to the transmission information is determined based on the priority relationship and transmission power difference mentioned above.

[0065] In one embodiment of this disclosure, the transmission power corresponding to each feedback message can be determined based on the PSFCH format corresponding to each feedback message.

[0066] This disclosure does not limit the PSFCH format; any available PSFCH format can be applied to this disclosure.

[0067] For example, suppose a predefined correspondence is established between the PSFCH format and the transmission power corresponding to the feedback information. For instance, the transmission power corresponding to the first PSFCH format is 1W, the transmission power corresponding to the second PSFCH format is 2W, and the transmission power corresponding to the third PSFCH format is 3W.

[0068] After receiving the transmission information, the PSFCH format of the corresponding feedback information is determined. Then, based on the correspondence between the PSFCH format and the transmission power of the corresponding feedback information, the transmission power of the corresponding feedback information is determined. For example, if the PSFCH format of the corresponding feedback information is the second PSFCH format, then the transmission power of the corresponding feedback information is determined to be 2W.

[0069] In one embodiment of this disclosure, the transmission power corresponding to each feedback message can be determined based on the priority of the PSFCH format corresponding to each feedback message.

[0070] For example, the first PSFCH format has a higher priority than the second PSFCH format, the second PSFCH format has a higher priority than the third PSFCH format, the lowest priority corresponds to a transmission power of x dBm, and the transmission power difference between two adjacent priorities is y dBm.

[0071] After receiving the transmission information, the PSFCH format of the feedback information corresponding to the transmission information is determined, and then the transmission power corresponding to the feedback information corresponding to the transmission information is determined based on the priority relationship and transmission power difference mentioned above.

[0072] In one embodiment of this disclosure, if a receiving device needs to transmit different information on multiple PSFCH resources simultaneously, such as when the receiving device simultaneously provides feedback on multiple PSCCH or PSSCH transmissions and simultaneously transmits CSIs corresponding to multiple transmitting devices, the power information of the receiving device on different resources is the same, or the corresponding power information is determined based on the QoS, priority, MCS, occupied resource size, number of layers, and transmission method (whether beaming is used for transmission) of the transmission information received from multiple transmitting devices; or, the corresponding power information is determined by monitoring the CSI of the link, monitoring the RSRP of the link, the distance to multiple transmitting devices, and the location of multiple transmitting devices.

[0073] In one embodiment of this disclosure, before determining the power information corresponding to each of the at least one feedback information corresponding to at least one transmission information, the feedback information transmission method provided in this embodiment may further include: determining the feedback information that needs to be abandoned for transmission until the transmission power of the transmitting device can support the number of feedback information that it transmits simultaneously.

[0074] Determining the power information corresponding to each of the at least one feedback information corresponding to at least one transmission information may include: determining the power information corresponding to each of the feedback information that was not abandoned during transmission.

[0075] As shown in Figure 2, Figure 2 illustrates a second flowchart of the feedback information transmission method provided in this disclosure. Based on the embodiment shown in Figure 1, the embodiment shown in Figure 2 adds S104 before S102: determining the feedback information that needs to be abandoned from transmission. S102 may include S1021: determining the power information corresponding to each feedback information among the feedback information that is not abandoned from transmission.

[0076] In this embodiment of the disclosure, the power information corresponding to each feedback information in the feedback information that has not been abandoned for transmission can be determined using the power information determination method described above. For details, please refer to the power information determination method described above. This embodiment of the disclosure will not elaborate on it here.

[0077] The following explanation will use transmission power as an example to illustrate the concept.

[0078] In one embodiment of this disclosure, feedback information that needs to be abandoned from transmission can be randomly selected.

[0079] In one embodiment of this disclosure, feedback information that needs to be abandoned for transmission can be determined based on third attribute information. The third attribute information includes any one of the following: the CSI of the monitoring link, the RSRP of the monitoring link, the distance to the device transmitting the transmission information, and the location of the device transmitting the transmission information.

[0080] For example, the distance to the device transmitting the aforementioned information will be used as an example for illustration.

[0081] Assuming the distance to the device transmitting the first transmission information is 1 kilometer and the distance to the device transmitting the second transmission information is 2 kilometers, then the feedback information that needs to be abandoned is the feedback information corresponding to the second transmission information.

[0082] In one embodiment of this disclosure, feedback information that needs to be abandoned for transmission can be determined based on the fourth attribute information of the transmitted information. The fourth attribute information may include any one of the following: QoS, priority, MCS, resource consumption of the transmitted information, and number of layers.

[0083] For example, let's take the priority of transmitting information as an example.

[0084] Assuming the priority of the first transmitted information is higher than that of the second transmitted information, the feedback information that needs to be abandoned is the feedback information corresponding to the second transmitted information.

[0085] In one embodiment of this disclosure, feedback information that needs to be abandoned for transmission can be determined based on the transmission method used to transmit the aforementioned transmission information. The transmission method may include: transmitting the transmission information using a beam or transmitting the transmission information without using a beam.

[0086] For example, suppose the first transmission information is not transmitted using a beam, but the second transmission information is transmitted using a beam. Then the feedback information that needs to be abandoned for transmission is the feedback information corresponding to the first transmission information.

[0087] In one embodiment of this disclosure, feedback information that needs to be abandoned for transmission can be determined based on the response status of the feedback information.

[0088] In one embodiment of this disclosure, if the feedback information corresponding to the non-acknowledgment response state corresponds to unicast transmission or multicast transmission based on the second feedback method, the feedback information that needs to be abandoned for transmission can be the feedback information corresponding to the non-acknowledgment response state.

[0089] For example, assuming that feedback information 1 corresponding to the unacknowledged response state corresponds to unicast transmission, feedback information 2 corresponding to the unacknowledged response state corresponds to multicast transmission based on the second feedback method, feedback information 3 corresponding to the unacknowledged response state corresponds to multicast transmission based on the second feedback method, and feedback information 4 corresponding to the acknowledged response state corresponds to multicast transmission based on the first feedback method, then the feedback information that needs to be abandoned for transmission can be the feedback information corresponding to feedback information 1, the feedback information corresponding to feedback information 2, and the feedback information corresponding to feedback information 3.

[0090] In one embodiment of this disclosure, if the feedback information corresponding to the non-acknowledgment response state corresponds to unicast transmission or multicast transmission based on the second feedback method, the feedback information that needs to be abandoned for transmission can be the feedback information corresponding to the acknowledgment response state.

[0091] For example, suppose that feedback information 1 corresponding to the unacknowledged response state corresponds to unicast transmission, feedback information 2 corresponding to the unacknowledged response state corresponds to multicast transmission based on the second feedback method, feedback information 3 corresponding to the unacknowledged response state corresponds to multicast transmission based on the second feedback method, and feedback information 4 corresponding to the acknowledgment response state corresponds to multicast transmission based on the first feedback method, then the feedback information that needs to be abandoned for transmission can be the feedback information corresponding to feedback information 4.

[0092] In one embodiment of this disclosure, if the feedback information corresponding to the non-acknowledgment response state corresponds to multicast transmission based on the first feedback method, the feedback information that needs to be abandoned for transmission is determined to be the feedback information corresponding to the non-acknowledgment response state.

[0093] For example, suppose that feedback information 1 corresponding to the unacknowledged response state corresponds to multicast transmission based on the first feedback method, feedback information 2 corresponding to the unacknowledged response state corresponds to multicast transmission based on the first feedback method, feedback information 3 corresponding to the acknowledged response state corresponds to unicast transmission, and feedback information 4 corresponding to the acknowledged response state corresponds to multicast transmission based on the second feedback method, then the feedback information that needs to be abandoned for transmission can be the feedback information corresponding to feedback information 1 and the feedback information corresponding to feedback information 2.

[0094] In one embodiment of this disclosure, if the feedback information corresponding to the non-acknowledgment response state corresponds to multicast transmission based on the first feedback method, the feedback information that needs to be abandoned for transmission is determined to be the feedback information corresponding to the acknowledgment response state.

[0095] For example, assuming that feedback information 1 corresponding to the unacknowledged response state corresponds to multicast transmission based on the first feedback method, feedback information 2 corresponding to the unacknowledged response state corresponds to multicast transmission based on the first feedback method, feedback information 3 corresponding to the acknowledged response state corresponds to unicast transmission, and feedback information 4 corresponding to the acknowledged response state corresponds to multicast transmission based on the second feedback method, then the feedback information that needs to be abandoned for transmission can be the feedback information corresponding to feedback information 3 and the feedback information corresponding to feedback information 4.

[0096] In one embodiment of this disclosure, if the feedback information corresponding to the non-acknowledgment response state corresponds to multicast transmission based on the first feedback method and multicast transmission not based on the first feedback method, the feedback information that needs to be abandoned for transmission is determined to be the feedback information corresponding to the non-acknowledgment response state of multicast transmission based on the first feedback method.

[0097] For example, assuming that feedback information 1 corresponding to the non-acknowledgment response state corresponds to multicast transmission based on the first feedback method, feedback information 2 corresponding to the non-acknowledgment response state corresponds to multicast transmission not based on the first feedback method, feedback information 3 corresponding to the non-acknowledgment response state corresponds to multicast transmission not based on the first feedback method, and feedback information 4 corresponding to the non-acknowledgment response state corresponds to multicast transmission based on the first feedback method, then the feedback information that needs to be abandoned for transmission can be the feedback information corresponding to feedback information 1 and the feedback information corresponding to feedback information 4.

[0098] In one embodiment of this disclosure, if the feedback information corresponding to the non-acknowledgment response state corresponds to multicast transmission based on the first feedback method and multicast transmission not based on the first feedback method, the feedback information that needs to be abandoned for transmission is determined to be the feedback information corresponding to the non-acknowledgment response state that corresponds to multicast transmission not based on the first feedback method.

[0099] For example, assuming that feedback information 1 corresponding to the non-acknowledgment response state corresponds to multicast transmission based on the first feedback method, feedback information 2 corresponding to the non-acknowledgment response state corresponds to multicast transmission not based on the first feedback method, feedback information 3 corresponding to the non-acknowledgment response state corresponds to multicast transmission not based on the first feedback method, and feedback information 4 corresponding to the non-acknowledgment response state corresponds to multicast transmission based on the first feedback method, then the feedback information that needs to be abandoned for transmission can be the feedback information corresponding to feedback information 2 and the feedback information corresponding to feedback information 3.

[0100] In one embodiment of this disclosure, when it is necessary to discard less than N feedback information corresponding to N confirmed response states; or, when it is necessary to discard less than N feedback information corresponding to N non-confirmed response states; or, when, in addition to discarding feedback information corresponding to confirmed response states, it is also necessary to discard one or more feedback information corresponding to non-confirmed response states; or, when, in addition to discarding feedback information corresponding to non-confirmed response states, it is also necessary to discard feedback information corresponding to one or more confirmed response states; the feedback information to be discarded can be randomly selected; or, the feedback information to be discarded can be determined based on the third attribute information of the channel state of the physical sidelink channel; or, the feedback information to be discarded can be determined based on the fourth attribute information of the transmitted information; or, the feedback information to be discarded can be determined based on the transmission method of the transmitted information.

[0101] In one embodiment of this disclosure, feedback information that needs to be abandoned for transmission can be determined based on the transmission type of at least one type of transmitted information.

[0102] For example, suppose the transmission type of transmission information 1 is unicast, the transmission type of transmission information 3 is multicast based on the first feedback method, the transmission type of transmission information 4 is multicast based on the second feedback method, and the transmission type of transmission information 4 is unicast. Then the feedback information that needs to be abandoned for transmission can be the feedback information corresponding to transmission information 1 and the feedback information corresponding to transmission information 4.

[0103] In one embodiment of this disclosure, feedback information that needs to be abandoned for transmission can be determined based on the priority corresponding to the transmission type of at least one type of transmitted information.

[0104] For example, suppose that unicast has higher priority than multicast based on the first feedback method, and multicast based on the first feedback method has higher priority than multicast based on the second feedback method.

[0105] Transmission type 1 is unicast, transmission type 2 is multicast based on the first feedback method, transmission type 3 is multicast based on the second feedback method, and transmission type 4 is multicast based on the first feedback method. Therefore, the feedback information that needs to be abandoned for transmission is the feedback information corresponding to transmission information 3.

[0106] In one embodiment of this disclosure, feedback information that needs to be abandoned for transmission can be determined based on the PSFCH format corresponding to each feedback information.

[0107] For example, suppose that the PSFCH format corresponding to feedback information 1 is the first PSFCH format, the PSFCH format corresponding to feedback information 2 is the second PSFCH format, the PSFCH format corresponding to feedback information 3 is the second PSFCH format, and the PSFCH format corresponding to feedback information 4 is the third PSFCH format. Then, the feedback information that needs to be abandoned for transmission can be feedback information 2 and feedback information 3.

[0108] In one embodiment of this disclosure, feedback information that needs to be abandoned for transmission can be determined based on the priority of the PSFCH format corresponding to each feedback information.

[0109] For example, assume that the first PSFCH format has a higher priority than the second PSFCH format, and the second PSFCH format has a higher priority than the third PSFCH format. Feedback information 1 corresponds to the first PSFCH format, feedback information 2 corresponds to the third PSFCH format, feedback information 3 corresponds to the second PSFCH format, and feedback information 4 corresponds to the third PSFCH format. Then, the feedback information that needs to be abandoned for transmission can be feedback information 2 and feedback information 4.

[0110] In one embodiment of this disclosure, before transmitting the corresponding feedback information on at least one PSFCH resource based on the power information corresponding to each feedback information, the feedback information transmission method provided in this embodiment may further include: performing logical operations on the feedback information for the same transmitting end to obtain the logical operation result of the feedback information for the same transmitting end; and transmitting the logical operation result of the feedback information for the same transmitting end on a predefined and pre-configured PSFCH resource.

[0111] In one embodiment of this disclosure, the logical operation can be a logical AND operation, a logical OR operation, or a logical AND-OR operation.

[0112] For example, assuming that the feedback information for sender X includes feedback information 1, feedback information 2, and feedback information 3, and the feedback information for sender Y includes feedback information 4 and feedback information 5, then logical operations are performed on feedback information 1, feedback information 2, and feedback information 3 to obtain the logical operation result for the feedback information for sender X, and logical operations are performed on feedback information 4 and feedback information 5 to obtain the logical operation result for the feedback information for sender Y. The logical operation result for the feedback information for sender X is configured on the first PSFCH channel resource, and the logical operation result for the feedback information for sender Y is configured on the second PSFCH channel resource.

[0113] In one embodiment of this disclosure, the PSFCH resource for configuring the logical operation result of the feedback information can be the PSFCH resource with the largest or smallest number in the PSFCH channel resources.

[0114] In one embodiment of this disclosure, it can be stipulated that when a receiving device simultaneously provides feedback on multiple transmitted messages from the same transmitting device, the receiving device must perform logical operations on the multiple feedback messages corresponding to the multiple transmitted messages. When the transmitting device receives feedback from the receiving device, it is assumed that the receiving device has performed logical operations on the multiple feedback messages corresponding to the multiple transmitted messages.

[0115] In one embodiment of this disclosure, the transmission power corresponding to the logical operation result of feedback information from the same transmitting end can be the sum of the transmission powers corresponding to the feedback information from the same transmitting end.

[0116] In one embodiment of this disclosure, before receiving at least one transmission information transmitted on at least one physical sidelink channel, the feedback information transmission method provided in this embodiment may further include: sending indication information to each transmitter, the indication information being used to indicate the physical sidelink channel resources used by each transmitter for transmission.

[0117] In one embodiment of this disclosure, the receiving device may notify the transmitting device of its physical sidelink channel resources used for transmission.

[0118] The receiving device can notify the sending device in the following ways:

[0119] Method 1: Notification is given in the form of physical sidelink channel resources. For example, the transmitting device is notified of the time-frequency resources and period of the physical sidelink channels used for transmission. Based on this, the indication information may include: the time-frequency resources of the physical sidelink channels used for transmission by each transmitting end and the period of the time-frequency resources. Another example is notifying the transmitting device of the set of time-frequency resources for the physical sidelink channels used for transmission and the period of the time-frequency resource set. Based on this, the indication information may include: the set of time-frequency resources for the physical sidelink channels used for transmission by each transmitting end and the period of the time-frequency resource set.

[0120] Method 2: Notify in the form of PSFCH occasion, for example, notify the transmitting device of the PSFCH occasion corresponding to the physical sidelink channel resources used for transmission and the period of the PSFCH occasion. Based on this, the indication information may include: the PSFCH occasion corresponding to the physical sidelink channel resources used for transmission by each transmitting end and the period of the PSFCH occasion.

[0121] Method 3: Notification via signaling. For example, the device sends information about its physical sidelink channel resources used for transmission via higher-layer or physical-layer signaling.
