[0026] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this disclosure.

[0027] The sidelink communication method provided in this disclosure can be applied to... Figure 1 The wireless communication system shown. (See attached image) Figure 1 As shown, this wireless communication system includes terminals and network devices. The terminals connect to the network devices via wireless resources and transmit data. The terminals can also communicate with each other via sidelinks using the PC5 interface.

[0028] Understandable Figure 1 The wireless communication system shown is for illustrative purposes only. A wireless communication system may also include other network devices, such as core network equipment, wireless relay equipment, and wireless backhaul equipment. Figure 1 Not shown in the diagram. This disclosure does not limit the number of network devices and terminals included in the wireless communication system.

[0029] It is further understood that the wireless communication system of this disclosure is a network providing wireless communication functionality. The wireless communication system can employ different communication technologies, such as code division multiple access (CDMA), wideband code division multiple access (WCDMA), time division multiple access (TDMA), frequency division multiple access (FDMA), orthogonal frequency-division multiple access (OFDMA), single carrier frequency division multiple access (SC-FDMA), and carrier sense multiple access with collision avoidance. Based on factors such as capacity, speed, and latency, networks can be categorized as 2G networks, 3G networks, 4G networks, or future evolution networks, such as 5G networks. 5G networks can also be referred to as New Radio (NR). For ease of description, this disclosure may sometimes simply refer to the wireless communication network as a network.

[0030] Furthermore, the network device involved in this disclosure can also be referred to as a wireless access network device. This wireless access network device can be: a base station, an evolved Node B (eBY), a home base station, an access point (AP) in a Wireless Fidelity (WIFI) system, a wireless relay node, a wireless backhaul node, a transmission point (TP), or a transmission and reception point (TRP), etc. It can also be a gNB in ​​an NR system, or a component or part of a base station. It should be understood that the specific technology and specific device form used in the embodiments of this disclosure are not limited. In this disclosure, the network device can provide communication coverage for a specific geographical area and can communicate with terminals located within that coverage area (cell). Furthermore, when it is a vehicle-to-everything (V2X) communication system, the network device can also be an in-vehicle device.

[0031] Furthermore, the terminal involved in this disclosure can also be referred to as a terminal device, user equipment (UE), mobile station (MS), mobile terminal (MT), etc., which is a device that provides voice and / or data connectivity to a user. For example, the terminal can be a handheld device with wireless connectivity, an in-vehicle device, etc. Currently, some examples of terminals include: smartphones, customer premise equipment (CPE), pocket personal computers (PPCs), handheld computers, personal digital assistants (PDAs), laptops, tablets, wearable devices, or in-vehicle devices, etc. In addition, when it is a vehicle-to-everything (V2X) communication system, the terminal device can also be an in-vehicle device. It should be understood that the embodiments of this disclosure do not limit the specific technology or specific device form adopted by the terminal.

[0032] The interfaces between base stations and between terminals can be defined by protocols such as LTE and NR, while the interfaces between terminals can be defined by the sidelink protocol to enable direct connection between two terminals.

[0033] As mentioned above, resource reservation schemes are supported between different devices based on sidelink communication. In related technologies, terminals in sidelink can reserve resources. When a terminal reserves resources, it sends an indication message indicating the resources it has reserved. After other terminals hear the indication message or detect that a resource is being used or reserved, the other terminals will not use or reserve the resource that is being used or reserved.

[0034] Currently, resource reservation in sidelink communication is based on omnidirectional orientation, meaning that beam direction is not considered. Therefore, how to implement beam-based resource reservation is under investigation.

[0035] Based on this, the present disclosure provides a sidelink communication method in which a device performing sidelink communication sends indication information, which indicates reserved resources and beam information corresponding to the reserved resources. Another device performing sidelink communication with the device that sends the indication information can determine the beam-based resource reservation based on the indication information, thereby improving the performance of beam-based sidelink transmission.

[0036] In this embodiment of the disclosure, beam refers to spatial relation information, spatial setting, spatial Rx parameter, spatial filter (Tx), spatial receive filters, spatial transmission filter (Spatial domain transmission filter), Transmission Configuration Indication (TCI) status, Quasi-Co Location (QCL) type D, etc.

[0037] For ease of description in this embodiment, the device that sends the instruction information is referred to as the first device, and the other device that receives the instruction information is referred to as the second device.

[0038] Figure 2 This is a flowchart illustrating a sidelink communication method according to an exemplary embodiment, such as... Figure 2 As shown, the sidelink communication method is executed by the first device and includes the following steps.

[0039] In step S11, an indication message is sent, which indicates the reserved resources and the beam information corresponding to the reserved resources.

[0040] Here, reserved resources refer to the resources reserved by the first device. The beam information corresponding to the reserved resources refers to the beam information corresponding to the beam used by the first device when transmitting channels and / or signals using the reserved resources.

[0041] In some embodiments, the first device sends indication information to the second device, the second device receives the indication information, and determines the reserved resources and the beam information corresponding to the reserved resources based on the indication information.

[0042] In this embodiment of the disclosure, the first device sends indication information, which is used to indicate reserved resources and beam information corresponding to the reserved resources, so that the second device that receives the indication information can determine the beam-based resource reservation based on the indication information, thereby improving the performance of sidelink beam-based transmission.

[0043] In a sidelink communication method provided in this embodiment, the beam information includes a reference signal identifier.

[0044] Among them, the sidelink channels and / or signals transmitted on the reserved resources have a quasi-co-address relationship with the reference signals identified by the reference signal identifier.

[0045] In some embodiments, the sidelink channel and / or signal includes at least one of the following: Physical Sidelink Share Channel (PSSCH); Physical Sidelink Control Channel (PSCCH); Physical Sidelink Feedback Channel (PSFCH); Physical Sidelink Broadcast Channel (PSBCH); Synchronization Signal / Physical Broadcast Channel Block (S-SS / PSBCH Block); Channel State Information Reference Signal (CSI-RS); Demodulation Reference Symbol (DMRS); and Phase Tracking Reference Signal (PT-RS).

[0046] In some embodiments, the reference signal identifier includes the sidelink's S-SS / PSBCH Block index and / or CSI-RS resource index.

[0047] In some embodiments, the beam information further includes at least one of the following:

[0048] sidelink spatial relation information;

[0049] Spatial settings for sidelinks;

[0050] Spatial Rx parameter of sidelink;

[0051] Tx spatial filter for sidelink;

[0052] sidelink spatial domain receive filters;

[0053] sidelink spatial domain transmission filters;

[0054] TCI status of the sidelink;

[0055] QCL type D for sidelink.

[0056] It is understood that, in the embodiments of this disclosure, beam information can be indicated by at least one of the following: sidelink spatial relation information, spatial setting, spatial Rx parameter, Tx spatial filter, spatial domain receive filters, spatial domain transmission filters, TCI status, and QCL type D.

[0057] In a sidelink communication method provided in this disclosure embodiment, indication information is used to indicate at least one set of beam information.

[0058] Each set of beam information includes at least one beam identifier. In the at least one beam identifier, different beam identifiers correspond to different antenna panels of the first device, and / or different beam identifiers correspond to different antenna panels of the second device.

[0059] In this embodiment of the disclosure, the beam identifier included in the beam information can be used to determine the beam and / or antenna panel used for channel and / or signal transmission on the reserved resources, thereby realizing beam-based resource reservation.

[0060] In a sidelink communication method provided in this disclosure embodiment, indication information is used to indicate the beam used for transmitting a first sidelink channel and / or signal.

[0061] In a sidelink communication method provided in this disclosure embodiment, indication information is used to indicate the beam used for transmitting a second sidelink channel and / or signal.

[0062] In a sidelink communication method provided in this disclosure embodiment, indication information is used to indicate the beam used for transmitting a first sidelink channel and / or signal, and the beam used for transmitting a second sidelink channel and / or signal.

[0063] In a sidelink communication method provided in this disclosure, when indication information is used to indicate a beam for transmitting a first sidelink channel and / or signal, a beam for transmitting a second sidelink channel and / or signal is determined based on the beam indicated by the indication information for transmitting the first sidelink channel and / or signal. For example, based on default rules and the beam indicated by the indication information for transmitting the first sidelink channel and / or signal, the beam for transmitting the second sidelink channel and / or signal is determined to be the same as the beam for transmitting the first sidelink channel and / or signal.

[0064] In the above embodiments, the first sidelink channel and / or signal is a sidelink channel and / or signal transmitted on the frequency domain resource configuration and / or time domain resource configuration indicated by the sidelink control information (SCI) where the indication information is located, and the second sidelink channel and / or signal is a sidelink channel and / or signal transmitted on reserved resources. The first sidelink channel and / or signal includes at least one of the following: PSSCH, PSCCH, PSFCH, PSBCH, S-SS / PSBCH Block, sidelink CSI-RS, sidelink DMRS, and sidelink PT-RS. The second sidelink channel and / or signal includes at least one of the following: PSSCH, PSCCH, PSFCH, PSBCH, S-SS / PSBCH Block, sidelink CSI-RS, sidelink DMRS, and sidelink PT-RS.

[0065] In some embodiments of a sidelink communication method provided in this disclosure, the indication information sent by the first device is used to indicate a set of beam information.

[0066] The indication information sent by the first device is used to indicate a set of beam information for the transmission of the first side link channel and / or signal and / or the second side link channel and / or signal.

[0067] For example, if the SCI containing the indication information is SCI 1-A, and SCI 1-A indicates the frequency domain resource configuration and / or time domain resource configuration corresponding to the first-side link channel and / or signal transmission, and the reserved resources are in SCI 1-A or SCI 2-C ​​scheduled by SCI 1-A, then the indication domain of this set of beam information can be carried in SCI 1-A or SCI 2-C ​​scheduled by SCI 1-A. That is, the first-side link channel and / or signal corresponds to the same beam information as the second-side link channel and / or signal.

[0068] In some other embodiments of a sidelink communication method provided in this disclosure, the indication information is used to indicate at least two sets of beam information, which include a first beam information and / or a second beam information.

[0069] The first beam information is used to indicate the beam used for the first side link channel and / or signal transmission, and the second beam information is used to indicate the beam used for the second side link channel and / or signal transmission.

[0070] In one embodiment, at least two sets of beam information include first beam information, which is used to indicate the beam of a first side link channel and / or signal transmission.

[0071] In one embodiment, at least two sets of beam information include second beam information, which is used to indicate the beams of a second side link channel and / or signal transmission.

[0072] In one embodiment, at least two sets of beam information include first beam information and second beam information, wherein the first beam information is used to indicate the beam of a first side link channel and / or signal transmission, and the second beam information is used to indicate the beam of a second side link channel and / or signal transmission.

[0073] In other embodiments of a sidelink communication method provided in this disclosure, indication information is used to indicate a set of third beam information, which indicates the beam of the second sidelink channel and / or signal transmitted on reserved resources in at least one time unit. That is, in this disclosure, the beam information corresponding to the reserved resources on all time units is the same.

[0074] In some embodiments, the first device can reserve resources on multiple time units. A time unit can be a slot or a mini-slot. A mini-slot is relative to scheduling using a slot as the time unit. When scheduling using a slot as the time unit, the minimum number of symbols occupied is 3; a mini-slot can occupy 1 or 2 symbols. Furthermore, a slot can include multiple scheduled mini-slot time units. A mini-slot can also occupy the symbols of two adjacent slots.

[0075] In some other embodiments of a sidelink communication method provided in this disclosure, indication information is used to indicate at least two sets of fourth beam information, and the at least two sets of fourth beam information are used to indicate the beams of the second sidelink channel and / or signal transmitted on reserved resources for at least two time units.

[0076] In this embodiment of the disclosure, reserved resources in different time units can correspond to different fourth beam information. Specifically, the reserved resources and fourth beam information in different time units can correspond one-to-one; or the reserved resources in multiple time units can correspond to a single set of fourth beam information. The correspondence between reserved resources and fourth beam information in different time units is determined based on default rules, or is explicitly indicated in the indication information.

[0077] In a sidelink communication method provided in this embodiment, the number of time units included in the reserved resources is M, and the indication information includes N sets of fourth beam information, where M is a positive integer and N is a positive integer greater than or equal to 2.

[0078] In some embodiments, N sets of fourth beam information correspond one-to-one with the side link channels and / or signals transmitted on the reserved resources of M time units; and / or, N sets of fourth beam information correspond one-to-one with the side link channels and / or signals transmitted on the reserved resources of N groups of time units, wherein the M time units are divided into N groups, and each group includes time units that are continuous or discontinuous.

[0079] In one implementation, in response to M=N, N sets of fourth beam information correspond one-to-one with the sidelink channels and / or signals transmitted on the reserved resources of M time units.

[0080] For example, if the number of time units included in the reserved resources is M=4, and at least two sets of beam information include N=4 sets of fourth beam information, then the 4 sets of fourth beam information correspond one-to-one with the side link channels and / or signals transmitted on the reserved resources of the 4 time units.

[0081] In another implementation, in response to M>N, the N sets of fourth beam information correspond one-to-one with the side link channels and / or signals transmitted on the reserved resources of the N time units.

[0082] For example, if the reserved resources include M=8 time units, and at least two sets of beam information include N=4 sets of fourth beam information, then the 4 sets of fourth beam information correspond one-to-one with the sidelink channels and / or signals transmitted on the reserved resources of the 4 time units. That is, each set of fourth beam information corresponds one-to-one with the sidelink channels and / or signals transmitted on the reserved resources of 2 time units. When the 8 time units are divided into 4 groups, the time units included in each group can be continuous or discontinuous. For example, if the time units included in each group are continuous, the first group includes the first and second time units, the second group includes the third and fourth time units, the third group includes the fifth and sixth time units, and the fourth group includes the seventh and eighth time units. Alternatively, if the time units included in each group are discontinuous, the first group includes the first and fifth time units, the second group includes the second and sixth time units, the third group includes the third and seventh time units, and the fourth group includes the fourth and eighth time units.

[0083] In a sidelink communication method provided in this disclosure embodiment, the beam information of the first sidelink channel and / or signal transmission is determined based on the time interval between the indication information and the first sidelink channel and / or signal. For example... Figure 3 As shown, it includes the following steps:

[0084] In step S21, beam information for transmission of the first side link channel and / or signal is determined based on the time interval between the indication information and the first side link channel and / or signal.

[0085] It should be noted that the indication information here includes the indication information of the first beam corresponding to the first side link channel and / or signal.

[0086] In some embodiments, when the time interval between the indication information and the first side link channel and / or signal is greater than or equal to a time interval threshold, the beam information of the transmission of the first side link channel and / or signal is determined based on the indication information; and / or, when the time interval between the indication information and the first side link channel and / or signal is less than the time interval threshold, the beam information of the transmission of the first side link channel and / or signal is determined based on a default rule.

[0087] In one embodiment, in response to the time interval between the indication information and the first side link channel and / or signal being greater than or equal to a time interval threshold, beam information for the transmission of the first side link channel and / or signal is determined based on the indication information.

[0088] In this embodiment of the disclosure, since the time interval between the indication information and the first side link channel and / or signal is greater than or equal to the time interval threshold, there is sufficient time to decode the indication information, thereby determining the beam information for the transmission of the first side link channel and / or signal based on the indication information.

[0089] In another implementation, in response to the time interval between the indication information and the first side link channel and / or signal being less than a time interval threshold, beam information for the transmission of the first side link channel and / or signal is determined based on default rules.

[0090] In this embodiment of the disclosure, since the time interval between the indication information and the first side link channel and / or signal is less than the time interval threshold, the time interval is too small to decode the beam information included in the indication information. Therefore, the beam information for the transmission of the first side link channel and / or signal is determined based on the default rules.

[0091] In a sidelink communication method provided in this embodiment, before sending indication information, the first device needs to determine whether the indication information includes beam information. For example... Figure 4 As shown, it includes the following steps:

[0092] In step S31, based on the configuration information, it is determined whether the indication information includes beam information corresponding to the reserved resources.

[0093] In one implementation, the configuration information is sent by a second device. This second device can be a second terminal or a network device.

[0094] In some embodiments, if the first device determines that the indication information includes beam information corresponding to the reserved resources based on the configuration information, then it sends the indication information, which is used to indicate the reserved resources and the beam information corresponding to the reserved resources.

[0095] In this embodiment of the disclosure, when the first device determines based on the configuration information that the indication information includes beam information corresponding to the reserved resources, it sends indication information for indicating the reserved resources and the beam information corresponding to the reserved resources, so that the second device can determine the beam-based resource reservation based on the indication information, thereby improving the performance of sidelink beam-based transmission.

[0096] In a sidelink communication method provided in this disclosure embodiment, the indication information is included in the SCI.

[0151] In step S41, indication information is received, which is used to indicate reserved resources and the beam information corresponding to the reserved resources.

[0152] Here, reserved resources refer to the resources reserved by the first device. The beam information corresponding to the reserved resources refers to the beam information corresponding to the beam used by the first device when transmitting channels and / or signals using the reserved resources.

[0153] In this embodiment of the disclosure, the second device receives indication information sent by the first device.

Thus, the second device can determine beam-based resource reservation based on the indication information, thereby improving the performance of sidelink beam-based transmission.

[0154] In a sidelink communication method provided in this embodiment, the beam information includes a reference signal identifier.

[0169] Each set of beam information includes at least one beam identifier, wherein different beam identifiers correspond to different antenna panels of the first device, and / or different beam identifiers correspond to different antenna panels of the second device.

[0173] In a sidelink communication method provided in this disclosure embodiment, indication information is used to indicate the beam used for transmitting a first sidelink channel and / or signal, and the beam used for transmitting a second sidelink channel and / or signal.

[0174] In a sidelink communication method provided in this disclosure, when indication information is used to indicate a beam for transmitting a first sidelink channel and / or signal, a beam for transmitting a second sidelink channel and / or signal is determined based on the beam indicated by the indication information for transmitting the first sidelink channel and / or signal. For example, based on default rules and the beam indicated by the indication information for transmitting the first sidelink channel and / or signal, the beam for transmitting the second sidelink channel and / or signal is determined to be the same as the beam for transmitting the first sidelink channel and / or signal.

[0175] In the above embodiments, the first sidelink channel and / or signal is a sidelink channel and / or signal transmitted on the frequency domain resource configuration and / or time domain resource configuration indicated by the sidelink control information (SCI) where the indication information is located, and the second sidelink channel and / or signal is a sidelink channel and / or signal transmitted on reserved resources. The first sidelink channel and / or signal includes at least one of the following: PSSCH, PSCCH, PSFCH, PSBCH, S-SS / PSBCH Block, sidelink CSI-RS, sidelink DMRS, and sidelink PT-RS. The second sidelink channel and / or signal includes at least one of the following: PSSCH, PSCCH, PSFCH, PSBCH, S-SS / PSBCH Block, sidelink CSI-RS, sidelink DMRS, and sidelink PT-RS.

[0176] In some embodiments of a sidelink communication method provided in this disclosure, the indication information sent by the first device is used to indicate a set of beam information.

[0177] The indication information sent by the first device is used to indicate a set of beam information for the transmission of the first side link channel and / or signal and / or the second side link channel and / or signal.

[0178] For example, if the SCI containing the indication information is SCI 1-A, and SCI 1-A indicates the frequency domain resource configuration and / or time domain resource configuration corresponding to the first-side link channel and / or signal transmission, and the reserved resources are in SCI 1-A or SCI 2-C ​​scheduled by SCI 1-A, then the indication domain of this set of beam information can be carried in SCI 1-A or SCI 2-C ​​scheduled by SCI 1-A. That is, the first-side link channel and / or signal corresponds to the same beam information as the second-side link channel and / or signal.

[0179] In some other embodiments of a sidelink communication method provided in this disclosure, the indication information is used to indicate at least two sets of beam information, which include a first beam information and / or a second beam information.

[0180] The first beam information is used to indicate the beam used for the first side link channel and / or signal transmission, and the second beam information is used to indicate the beam used for the second side link channel and / or signal transmission.

[0181] In one embodiment, at least two sets of beam information include first beam information, which is used to indicate the beam of a first side link channel and / or signal transmission.

[0182] In one embodiment, at least two sets of beam information include second beam information, which is used to indicate the beams of a second side link channel and / or signal transmission.

[0183] In one embodiment, at least two sets of beam information include first beam information and second beam information, wherein the first beam information is used to indicate the beam of a first side link channel and / or signal transmission, and the second beam information is used to indicate the beam of a second side link channel and / or signal transmission.

[0184] In some other embodiments of a sidelink communication method provided in this disclosure, indication information is used to indicate a set of third beam information, which indicates the beam of a second sidelink channel and / or signal transmitted on reserved resources of at least one time unit.

[0185] In other words, in this embodiment of the disclosure, the beam information corresponding to the reserved resources on all time units is the same.

[0186] In some embodiments, the first device can reserve resources on multiple time units. A time unit can be a slot or a mini-slot. A mini-slot is relative to scheduling using a slot as the time unit. When scheduling using a slot as the time unit, the minimum number of symbols occupied is 3; a mini-slot can occupy 1 or 2 symbols. Furthermore, a slot can include multiple scheduled mini-slot time units. A mini-slot can also occupy the symbols of two adjacent slots.

[0187] In some other embodiments of a sidelink communication method provided in this disclosure, indication information is used to indicate at least two sets of fourth beam information, and the at least two sets of fourth beam information are used to indicate the beams of the second sidelink channel and / or signal transmitted on reserved resources for at least two time units.

[0188] In other words, in this embodiment of the disclosure, the reserved resources in different time units can correspond to different fourth beam information. Specifically, the reserved resources and fourth beam information in different time units can correspond one-to-one; or the reserved resources in multiple time units can correspond to a set of fourth beam information. The correspondence between the reserved resources and fourth beam information in different time units is determined based on default rules, or is explicitly indicated in the indication information.

[0189] In a sidelink communication method provided in this embodiment, the number of time units included in the reserved resources is M, and the indication information includes N sets of fourth beam information, where M is a positive integer and N is a positive integer greater than or equal to 2.

[0190] In some embodiments, N sets of fourth beam information correspond one-to-one with the side link channels and / or signals transmitted on the reserved resources of M time units; and / or, N sets of fourth beam information correspond one-to-one with the side link channels and / or signals transmitted on the reserved resources of N groups of time units, wherein the M time units are divided into N groups, and each group includes time units that are continuous or discontinuous.

[0191] In one implementation, in response to M=N, N sets of fourth beam information correspond one-to-one with the sidelink channels and / or signals transmitted on the reserved resources of M time units.

[0192] For example, if the number of time units included in the reserved resources is M=4, and at least two sets of beam information include N=4 sets of fourth beam information, then the 4 sets of fourth beam information correspond one-to-one with the side link channels and / or signals transmitted on the reserved resources of the 4 time units.

[0193] In another implementation, in response to M>N, the N sets of fourth beam information correspond one-to-one with the side link channels and / or signals transmitted on the reserved resources of the N time units.

[0194] For example, if the reserved resources include M=8 time units, and at least two sets of beam information include N=4 sets of fourth beam information, then the 4 sets of fourth beam information correspond one-to-one with the sidelink channels and / or signals transmitted on the reserved resources of the 4 time units. That is, each set of fourth beam information corresponds one-to-one with the sidelink channels and / or signals transmitted on the reserved resources of 2 time units. When the 8 time units are divided into 4 groups, the time units included in each group can be continuous or discontinuous. For example, if the time units included in each group are continuous, the first group includes the first and second time units, the second group includes the third and fourth time units, the third group includes the fifth and sixth time units, and the fourth group includes the seventh and eighth time units. Alternatively, if the time units included in each group are discontinuous, the first group includes the first and fifth time units, the second group includes the second and sixth time units, the third group includes the third and seventh time units, and the fourth group includes the fourth and eighth time units.

[0195] In a sidelink communication method provided in this disclosure embodiment, the beam information of the first sidelink channel and / or signal transmission is determined based on the time interval between the indication information and the first sidelink channel and / or signal.

[0196] It should be noted that the indication information here includes the indication information of the first beam corresponding to the first side link channel and / or signal.

[0197] In some embodiments, when the time interval between the indication information and the first side link channel and / or signal is greater than or equal to a time interval threshold, the beam information of the transmission of the first side link channel and / or signal is determined based on the indication information; and / or, when the time interval between the indication information and the first side link channel and / or signal is less than the time interval threshold, the beam information of the transmission of the first side link channel and / or signal is determined based on a default rule.

[0198] In one embodiment, in response to the time interval between the indication information and the first side link channel and / or signal being greater than or equal to a time interval threshold, the beam information of the transmission of the first side link channel and / or signal is determined based on the indication information.

[0199] In this embodiment of the disclosure, since the time interval between the indication information and the first side link channel and / or signal is greater than or equal to the time interval threshold, there is sufficient time to decode the indication information, thereby determining the beam information of the transmission of the first side link channel and / or signal based on the indication information.

[0200] In another implementation, in response to the time interval between the indication information and the first side link channel and / or signal being less than a time interval threshold, the beam information for the transmission of the first side link channel and / or signal is determined based on default rules.

[0201] In this embodiment of the disclosure, since the time interval between the indication information and the first side link channel and / or signal is less than the time interval threshold, the time interval is too small to decode the beam information included in the indication information. Therefore, the beam information of the transmission of the first side link channel and / or signal is determined based on the default rules.

[0202] In a sidelink communication method provided in this embodiment, before receiving indication information, the second device needs to determine whether the indication information includes beam information. For example... Figure 6 As shown, it includes the following steps:

[0203] In step S51, configuration information is determined. The configuration information is used to instruct the second device to determine whether the indication information includes beam information corresponding to the reserved resources.

[0204] In some embodiments, if the second device determines that the indication information includes beam information corresponding to the reserved resources based on the configuration information, then the reserved resources and the beam information corresponding to the reserved resources are determined based on the indication information sent by the first device.

[0205] In this embodiment of the disclosure, when the second device determines that the indication information includes beam information corresponding to the reserved resources based on the configuration information, it determines the reserved resources and the beam information corresponding to the reserved resources based on the indication information sent by the first device. Thus, the second device can determine the beam-based resource reservation based on the indication information, thereby improving the performance of sidelink beam-based transmission.

[0206] In a sidelink communication method provided in this disclosure embodiment, the indication information is included in the SCI.
