[0026] It can be further understood that the wireless communication system of the embodiments of the present disclosure is a network that provides a wireless communication function. The wireless communication system can use 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 FDMA (SC-FDMA), Carrier Sense Multiple Access with Collision Avoidance, and the like. Depending on the capacity, rate, latency, and the like of different networks, the networks can be classified into 2G, 3G, 4G, or future evolution networks, such as The 5th Generation Wireless Communication System (5G) networks, which can also be referred to as New Radio (NR) networks. For the convenience of description, the wireless communication network can be referred to as a network in the present disclosure.

[0027] Further, the network device not shown in the present disclosure Figure 1 The network device not shown in the present disclosure can include a radio access network device. The radio access network device can be a base station, an evolved Node B (eNB), 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 receiving point (TRP), and the like, and can also be a gNB in an NR system, or can also be a component or a part of a device constituting a base station, and the like. When it is a vehicle-to-everything (V2X) communication system, the network device can also be a vehicle-mounted device. It should be understood that the specific technology and specific device form of the access network device are not limited in the embodiments of the present disclosure.

[0028] Further, the first terminal 110, the second terminal 120 and the third terminal 130 involved in the present disclosure can also be referred to as terminal devices, user equipment (UE), mobile stations (MS), mobile terminals (MT) and the like, which are devices providing voice and / or data connectivity to users, such as handheld devices with wireless connection capability, vehicle-mounted devices and the like. Currently, some examples of the terminal are mobile phones, pocket personal computers (PPC), palmtop computers, personal digital assistants (PDA), notebook computers, tablet computers, wearable devices, or vehicle-mounted devices, and the like. In addition, when it is a vehicle-to-everything (V2X) communication system, the terminal can also be a vehicle-mounted device. It should be understood that the present embodiment does not limit the specific technology and specific device form of the terminal.

[0029] In the present embodiment, the network device, the first terminal 110, the second terminal 120 and the third terminal 130 can use any feasible wireless communication technology to realize mutual transmission of data. Wherein, the transmission channel corresponding to the data or control information transmitted by the network device to the first terminal 110, the second terminal 120 and the third terminal 130 is called downlink (DL), and the transmission channel corresponding to the data or control information transmitted by the first terminal 110, the second terminal 120 and the third terminal 130 to the network device is called uplink (UL). It can be understood that the access network device involved in the present embodiment can be a base station. Of course, the access network device can also be any other possible access network device, and the terminal can be any possible terminal, which is not limited by the present disclosure.

[0030] In the present embodiment, the transmission channel between the first terminal 110, the second terminal 120 and the third terminal 130 can be referred to as sidelink. It is used for different terminals to send and receive data or control information.

[0031] In NR, especially when the communication frequency band is in frequency range 2, due to the rapid attenuation of high frequency channel, in order to ensure the coverage, it is necessary to use beam-based transmission and reception. It can be understood that the frequency of frequency range 2 is usually above 6GHz. In order to realize beam-based transmission, beam measurement is needed. In NR, at least one of SSB and CSI-RS is mainly used for beam measurement.

[0032] The beam can also be referred to as spatial relation information, spatial setting, spatial receive parameter (spatial RX parameter), transmit spatial filter (Tx spatial filter), spatial domain receive filter, spatial domain transmission filter, transmission configuration indication (TCI) state, quasi co location (QCL) type D, and the like.

[0033] In some schemes, a beam measurement and reporting method for sidelink has been provided, and resource reservation can also be performed in the sidelink. After performing resource reservation for the sidelink, the terminal sends reservation resource indication information reserved by the device. After receiving the reservation resource indication information, other terminals can perform sensing to find that the resource is being used or reserved. Other terminals will not use or reserve the resource that has been used or reserved by some terminals.

[0034] Currently, the sidelink communication has been widely applied, and how to determine whether the resources of different terminals conflict in the sidelink communication is currently being researched and has not yet been concluded.

[0035] Therefore, the present disclosure provides a sidelink resource conflict determination method, device, equipment and storage medium. By obtaining sidelink reservation resources reserved by other terminals, it is determined whether there is a resource conflict between different terminals performing sidelink transmission, and the transmission performance based on sidelink transmission is improved.

[0036] Figure 2 A sidelink resource conflict determination method flowchart according to an exemplary embodiment is shown in FIG. 1. As shown in FIG. 1, the method is performed by a terminal, which can be a first terminal. The method can include the following steps: Figure 2

[0037] In step S11, first sidelink reservation information of a second terminal and second sidelink reservation information of a third terminal are determined.

[0038] ​In some embodiments, the first terminal can determine first sidelink reservation information of the second terminal, and determine second sidelink reservation information of the third terminal. The first sidelink reservation information includes first reservation resource information and / or first reservation beam information; the second sidelink reservation information includes second reservation resource information and / or second reservation beam information.

[0039] It can be understood that the first reservation resource information corresponds to the first reservation beam information, that is, the transmission of the channel and / or the signal on the first reservation resource indicated by the first reservation resource information will be transmitted based on the beam indicated by the first reservation beam information; the second reservation resource information corresponds to the second reservation beam information, that is, the transmission of the channel and / or the signal on the second reservation resource indicated by the second reservation resource information will be transmitted based on the beam indicated by the second reservation beam information.

[0040] For example, the first sidelink reservation information includes the first reservation resource information and the first reservation beam information, and the second sidelink reservation information includes the second reservation resource information and the second reservation beam information.

[0041] For another example, the first sidelink reservation information can include one of the first reservation resource information and the first reservation beam information, and the second sidelink reservation information includes the second reservation resource information and the second reservation beam information.

[0042] For another example, the first sidelink reservation information includes the first reservation resource information and the first reservation beam information, and the second sidelink reservation information can include one of the second reservation resource information and the second reservation beam information.

[0043] For another example, the first sidelink reservation information can include one of the first reservation resource information and the first reservation beam information, and the second sidelink reservation information can include one of the second reservation resource information and the second reservation beam information.

[0044] The channel and / or signal transmitted on the first reserved resource and / or the second reserved resource can include at least one of the following: a physical sidelink shared channel (PSSCH); a physical sidelink control channel (PSCCH); a physical sidelink feedback channel (PSFCH); a physical sidelink broadcast channel (PSBCH); a sidelink synchronization signal or a physical sidelink broadcast channel signal block (S-SS / PSBCH Block); a sidelink channel state information reference signal (CSI-RS); a sidelink demodulation reference symbol (DMRS); and a sidelink phase tracking reference signal (PT-RS).

[0045] For example, the first terminal can receive first sidelink reservation information sent by the second terminal. The first terminal can also receive second sidelink reservation information sent by the third terminal. It can be understood that the first sidelink reservation information can be related resources reserved by the second terminal for sidelink transmission. For example, it includes first reserved resource information and first reserved beam information. The second sidelink reservation information can be related resources reserved by the third terminal for sidelink transmission. For example, it includes second reserved resource information and second reserved beam information.

[0046] The first reserved resource information is used to indicate the first reserved resource reserved by the second terminal for sidelink communication. The first reserved beam information is used to indicate the first reserved beam reserved by the second terminal for sidelink communication. The first reserved resource information corresponds to the first reserved beam information, that is, the second terminal performs sidelink communication on the first reserved resource through the first reserved beam.

[0047] The second reserved resource information is used to indicate a second reserved resource reserved by the third terminal for sidelink communication. The second reserved beam information is used to indicate a second reserved beam reserved by the third terminal for sidelink communication. The second reserved resource information corresponds to the second reserved beam information, that is, the third terminal performs sidelink communication on the second reserved resource through the second reserved beam.

[0048] In some embodiments, the first reserved beam and / or the second reserved beam mentioned above can be indicated by at least one of the following: sidelink spatial relation information; sidelink spatial setting; sidelink spatial RX parameter; sidelink Tx spatial filter; sidelink spatial domain receive filter; sidelink spatial domain transmission filter; sidelink TCI state; sidelink QCL typeD.

[0049] Meanwhile, the beam identifier corresponding to the first reserved beam and / or the second reserved beam mentioned above can include at least one of the following: sidelink CSI-RS resource identifier; sidelink synchronization signal and physical sidelink broadcast channel (S-SS / PSBCH Block) identifier; slot identifier corresponding to the reference signal resource; mini-slot identifier corresponding to the reference signal resource. It can be understood that the reference signal indicated by the reference signal identifier mentioned above has a QCL relationship with the channel / signal transmitted on the corresponding reserved resource. For example, the reference signal indicated by the reference signal identifier included in the first reserved beam has a QCL relationship with the channel / signal transmitted on the first reserved resource. For another example, the reference signal indicated by the reference signal identifier included in the second reserved beam has a QCL relationship with the channel / signal transmitted on the second reserved resource.

[0050] Of course, in some embodiments, the second terminal can also send the first sidelink reservation information to the network device, and the network device sends it to the first terminal. And / or, the third terminal can also send the second sidelink reservation information to the network device, and the network device sends it to the first terminal.

[0051] In step S12, based on the first sidelink reservation information and the second sidelink reservation information, it is determined that the second terminal and the third terminal have resource conflicts.

[0052] In some embodiments, the first terminal can determine whether there is a resource conflict between the second terminal and the third terminal based on the first sidelink reservation information and the second sidelink reservation information determined in S11.

[0053] For example, it is determined that there is a resource conflict between the second terminal and the third terminal. For another example, it is determined that there is no resource conflict between the second terminal and the third terminal.

[0054] It can be understood that the first terminal and the second terminal will perform sidelink communication based on the first reserved resource and / or the first reserved beam indicated by the first sidelink reservation information, and / or the first terminal and the third terminal will perform sidelink communication based on the second reserved resource and / or the second reserved beam indicated by the second sidelink reservation information.

[0055] The present disclosure improves the transmission performance based on sidelink transmission by determining whether there is a resource conflict between different terminals performing sidelink transmission based on the sidelink reservation resources reserved by other terminals.

[0056] The sidelink resource conflict determination method provided by the embodiments of the present disclosure includes the following steps: Figure 3 is another sidelink resource conflict determination method flowchart according to an exemplary embodiment. As shown in Figure 3 Based on the first sidelink reservation information and the second sidelink reservation information, it is determined that there is a resource conflict between the second terminal and the third terminal in S12, which can also include the following steps:

[0057] In step S21, in response to the first sidelink reservation information and the second sidelink reservation information satisfying a certain condition, the reference signal receiving power (RSRP) of the second terminal and / or the RSRP of the third terminal are determined.

[0058] In some embodiments, the first terminal can determine the RSRP of the second terminal and / or the RSRP of the third terminal in response to the first sidelink reservation information and the second sidelink reservation information satisfying a certain condition.

[0059] In some embodiments, the first terminal determines one or more of the RSRP of the second terminal and the RSRP of the third terminal, which can depend on which terminal the first terminal is a receiving terminal for, and which way the first terminal uses to determine whether there is a resource conflict between the second terminal and the third terminal based on the RSRP.

[0060] For example, if the first terminal focuses on comparing the RSRP of the interfering terminal with a corresponding threshold to determine whether there is a resource conflict, the first terminal can determine the RSRP of the interfering terminal. The interfering terminal refers to a terminal that is not the receiving terminal of the first terminal, and for the first terminal, this terminal is the interfering terminal.

[0061] For example, in response to the first terminal being the receiving terminal of the third terminal, the RSRP of the second terminal is determined.

[0062] For example, the first terminal is the receiving terminal of the third terminal, that is, when the first terminal and the third terminal perform sidelink communication, the first terminal receives sidelink data and the third terminal transmits sidelink data. Then the RSRP of the second terminal can be determined. It can be understood that since the first terminal is the receiving terminal of the third terminal, the first terminal should consider the interference of the second terminal to the first terminal. Therefore, the first terminal needs to consider the interference of the channel and / or signal transmitted by the second terminal to the first terminal.

[0063] It can be understood that the first terminal being the receiving terminal of the third terminal means that the first terminal is the receiving terminal of the third terminal on the second reserved resource and / or the second reserved beam.

[0064] For example, in response to the first terminal being the receiving terminal of the second terminal, the RSRP of the third terminal is determined.

[0065] For example, the first terminal is the receiving terminal of the second terminal, that is, when the first terminal and the second terminal perform sidelink communication, the first terminal receives sidelink data and the second terminal transmits sidelink data. Then the RSRP of the third terminal can be determined. It can be understood that since the first terminal is the receiving terminal of the second terminal, the first terminal should consider the interference of the third terminal to the first terminal. Therefore, the first terminal needs to consider the interference of the channel and / or signal transmitted by the third terminal to the first terminal.

[0066] It can be understood that the first terminal being the receiving terminal of the second terminal means that the first terminal is the receiving terminal of the second terminal on the first reserved resource and / or the first reserved beam.

[0067] For example, in response to the first terminal being the receiving terminal of the second terminal and the receiving terminal of the third terminal, the RSRP of the terminal with a higher priority value between the second terminal and the third terminal is determined, wherein the higher the priority value, the lower the priority of the corresponding terminal.

[0068] For example, if the first terminal is a receiving terminal for the second terminal and a receiving terminal for the third terminal. The first terminal can determine which of the second terminal and the third terminal has a higher priority, and the terminal with the higher priority is taken as the sending terminal, and the terminal with the lower priority is taken as the interference terminal. The priority size can be determined based on the priority value, and the terminal with a higher priority value corresponds to a lower priority. Therefore, the terminal with a higher priority value means that the terminal has a lower priority and is taken as the interference terminal. Conversely, the terminal with a lower priority value means that the terminal has a higher priority and is taken as the sending terminal.

[0069] For example, if the priority value of the second terminal is higher than the priority value of the third terminal, it means that the priority of the second terminal is lower than the third terminal. Therefore, the second terminal will be taken as the interference terminal, and the third terminal will be taken as the sending terminal.

[0070] For another example, if the first terminal focuses on the offset between the RSRP of the interference terminal and the RSRP of the sending terminal, such as comparing the offset with the corresponding threshold to determine whether there is a resource conflict between the second terminal and the third terminal, the first terminal needs to determine the RSRP of the interference terminal and the RSRP of the sending terminal.

[0071] For example, in response to the first terminal being a receiving terminal for the second terminal and the third terminal being an interference terminal, the first terminal needs to determine the offset between the RSRP of the interference terminal and the RSRP of the sending terminal, and determine whether there is a resource conflict between the second terminal and the third terminal based on the relationship between the offset and the corresponding threshold. The first terminal can determine the RSRP of the second terminal and the RSRP of the third terminal at the same time.

[0072] For another example, in response to the first terminal being a receiving terminal for the third terminal and the second terminal being an interference terminal, the first terminal needs to determine the offset between the RSRP of the interference terminal and the RSRP of the sending terminal, and determine whether there is a resource conflict between the second terminal and the third terminal based on the relationship between the offset and the corresponding threshold. The first terminal can determine the RSRP of the second terminal and the RSRP of the third terminal at the same time.

[0073] For another example, in response to the first terminal being a receiving terminal for the second terminal and a receiving terminal for the third terminal, one of the second terminal and the third terminal is an interference terminal, and the other is a sending terminal. The first terminal needs to determine the offset between the RSRP of the interference terminal and the RSRP of the sending terminal, and determine whether there is a resource conflict between the second terminal and the third terminal based on the relationship between the offset and the corresponding threshold. The first terminal can determine the RSRP of the second terminal and the RSRP of the third terminal at the same time.

[0074] Understandably, in this scenario, which terminal among the second and third terminals acts as the interfering terminal and which as the transmitting terminal can be determined based on their priority (or priority value). For example, the terminal with the higher priority (i.e., lower priority value) can be used as the transmitting terminal, and the other terminal as the interfering terminal.

[0075] In step S22, based on the RSRP of the second terminal and / or the RSRP of the third terminal, it is determined that there is a resource conflict between the second terminal and the third terminal.

[0076] In some implementations, the first terminal may determine whether there is a resource conflict between the second terminal and the third terminal based on the RSRP of the second terminal and / or the RSRP of the third terminal determined in S21.

[0077] For example, the first terminal can determine that there is a resource conflict between the second terminal and the third terminal based on the RSRP of the second terminal and / or the RSRP of the third terminal. Alternatively, the first terminal can determine that there is no resource conflict between the second terminal and the third terminal based on the RSRP of the second terminal and / or the RSRP of the third terminal.

[0078] Under certain conditions, this disclosure determines the RSRP of a corresponding terminal by obtaining the sidelink reserved resources reserved by other terminals, thereby determining whether there is a resource conflict between different terminals performing sidelink transmission, and improving the transmission performance based on sidelink transmission.

[0079] In the sidelink resource conflict determination method provided in this disclosure, determining the RSRP of the second terminal may include: determining the RSRP of the second terminal based on the beam of the third terminal or the beam of the second terminal.

[0080] In some embodiments, the first terminal may determine the RSRP of the second terminal based on the beam of the third terminal or the beam of the second terminal. It should be noted that the RSRP of the second terminal includes the RSRP obtained by measurement based on the PSSCH and / or PSCCH transmitted by the second terminal.

[0081] For example, the first terminal determines the RSRP of the second terminal based on the beam of the second terminal. The first side link reservation information of the second terminal includes first reserved beam information. The first reserved beam information is used to indicate the first reserved beam.

[0082] For example, if the first reserved beam is the same as the beam currently used by the second terminal to transmit the PSSCH and / or the PSCCH, the first terminal can determine the RSRP of the second terminal based on the first reserved beam. That is, the first terminal can determine the RSRP of the second terminal based on the beam currently used by the second terminal to transmit the PSSCH and / or the PSCCH, or the first terminal can determine the RSRP of the second terminal based on the first reserved beam.

[0083] For another example, if the first reserved beam is different from the beam currently used by the second terminal to transmit the PSSCH and / or the PSCCH, the first terminal can determine the RSRP of the second terminal based on the beam currently used by the second terminal to transmit the PSSCH and / or the PSCCH. That is, the first terminal can determine the RSRP of the second terminal based on the beam currently used by the second terminal to transmit the PSSCH and / or the PSCCH.

[0084] For another example, if the first reserved beam is different from the beam currently used by the second terminal to transmit the PSSCH and / or the PSCCH, the first terminal can determine the RSRP of the second terminal based on the first reserved beam. That is, the first terminal can determine the RSRP of the second terminal based on the first reserved beam.

[0085] It can be understood that, if the first reserved beam is the same as the beam currently used by the second terminal to transmit the PSSCH and / or the PSCCH, it is indifferent whether the RSRP of the second terminal is determined based on the beam currently used by the second terminal to transmit the PSSCH and / or the PSCCH or based on the first reserved beam. If the first reserved beam is different from the beam currently used by the second terminal to transmit the PSSCH and / or the PSCCH, the RSRP of the second terminal can be determined based on the beam currently used by the second terminal to transmit the PSSCH and / or the PSCCH or based on the first reserved beam according to a preset rule or protocol.

[0086] For another example, the first terminal can also determine the RSRP of the second terminal based on omnidirectional reception. It can be understood that omnidirectional reception is opposite to beam reception. Beam reception refers to reception with a relatively clear direction, a relatively small reception range, and only for the corresponding range indicated by the beam. Omnidirectional reception refers to reception without beam, that is, a relatively large reception direction range, such as omnidirectional reception.

[0087] For another example, the first terminal determines the RSRP of the second terminal based on the beam of the third terminal. The second reserved beam is included in the second sidelink reservation information of the third terminal.

[0088] For example, if the second reserved beam is the same as the beam currently used by the third terminal to transmit the PSSCH and / or the PSCCH, the first terminal can determine the RSRP of the second terminal based on the second reserved beam. That is, the first terminal can determine the RSRP of the second terminal based on the beam currently used by the third terminal to transmit the PSSCH and / or the PSCCH, or the first terminal can determine the RSRP of the second terminal based on the second reserved beam.

[0089] For example, if the second reserved beam is different from the beam currently used by the third terminal to transmit the PSSCH and / or the PSCCH, the first terminal can determine the RSRP of the second terminal based on the beam currently used by the third terminal to transmit the PSSCH and / or the PSCCH. That is, the first terminal can determine the RSRP of the second terminal based on the beam currently used by the third terminal to transmit the PSSCH and / or the PSCCH.

[0090] For example, if the second reserved beam is different from the beam currently used by the third terminal to transmit the PSSCH and / or the PSCCH, the first terminal can determine the RSRP of the second terminal based on the second reserved beam. That is, the first terminal can determine the RSRP of the second terminal based on the second reserved beam.

[0091] It can be understood that, if the second reserved beam is the same as the beam currently used by the third terminal to transmit the PSSCH and / or the PSCCH, it is irrelevant whether the RSRP of the second terminal is determined based on the beam currently used by the third terminal to transmit the PSSCH and / or the PSCCH or based on the second reserved beam. If the second reserved beam is different from the beam currently used by the third terminal to transmit the PSSCH and / or the PSCCH, the RSRP of the second terminal can be determined based on the beam currently used by the third terminal to transmit the PSSCH and / or the PSCCH or based on the second reserved beam according to a preset rule or protocol.

[0092] It can be understood that the PSCCH currently transmitted by each terminal refers to the PSCCH corresponding to the sidelink control information (SCI) containing the corresponding sidelink reservation information, or the PSCCH corresponding to the first-stage SCI corresponding to the second-stage SCI.

[0093] In addition, the PSSCH currently transmitted by each terminal refers to the PSSCH transmitted on the frequency domain resources and time domain resources indicated by the SCI containing the corresponding sidelink reservation information or the first-stage SCI corresponding to the second-stage SCI.

[0094] The present disclosure provides various ways to determine the RSRP of the second terminal, so as to determine whether there is a resource conflict between different terminals performing sidelink transmission, thereby improving the transmission performance based on sidelink transmission.

[0095] In the sidelink resource conflict determination method provided by the embodiments of the present disclosure, the RSRP of the third terminal can be determined based on the beam of the second terminal or the beam of the third terminal.

[0096] In some embodiments, the first terminal can determine the RSRP of the third terminal based on the beam of the second terminal or the beam of the third terminal. It should be noted that the RSRP of the third terminal includes the RSRP obtained by measuring the PSSCH and / or PSCCH transmitted by the third terminal.

[0097] For example, the first terminal determines the RSRP of the third terminal based on the beam of the third terminal. The second reserved beam in the second sidelink reservation information of the third terminal includes the second reserved beam.

[0098] For example, if the second reserved beam is the same as the beam currently used by the third terminal to transmit the PSSCH and / or PSCCH, the first terminal can determine the RSRP of the third terminal based on the second reserved beam. That is, the first terminal can determine the RSRP of the third terminal based on the beam currently used by the third terminal to transmit the PSSCH and / or PSCCH, or the first terminal can determine the RSRP of the third terminal based on the second reserved beam.

[0099] For another example, if the second reserved beam is different from the beam currently used by the third terminal to transmit the PSSCH and / or PSCCH, the first terminal can determine the RSRP of the third terminal based on the beam currently used by the third terminal to transmit the PSSCH and / or PSCCH. That is, the first terminal can determine the RSRP of the third terminal based on the beam currently used by the third terminal to transmit the PSSCH and / or PSCCH.

[0100] For another example, if the second reserved beam is different from the beam currently used by the third terminal to transmit the PSSCH and / or PSCCH, the first terminal can determine the RSRP of the third terminal based on the second reserved beam. That is, the first terminal can determine the RSRP of the third terminal based on the second reserved beam.

[0101] It can be understood that if the second reserved beam is the same as the beam currently used by the third terminal to transmit the PSSCH and / or PSCCH, it is indifferent whether the RSRP of the third terminal is determined based on the beam currently used by the third terminal to transmit the PSSCH and / or PSCCH or based on the second reserved beam. If the second reserved beam is different from the beam currently used by the third terminal to transmit the PSSCH and / or PSCCH, the RSRP of the third terminal can be determined based on the beam currently used by the third terminal to transmit the PSSCH and / or PSCCH or based on the second reserved beam according to a preset rule or protocol.

[0102] For another example, the first terminal can determine the RSRP of the third terminal based on the omni-directional reception. It can be understood that the omni-directional reception is opposite to the beam-based reception. The beam-based reception refers to the reception with a relatively clear directionality, and the reception range is small and only targets the corresponding range indicated by the beam. The omni-directional reception refers to the reception without the beam-based reception, i.e., the reception range is large, such as the omni-direction.

[0103] For another example, the first terminal determines the RSRP of the third terminal based on the beam of the second terminal. The first reserved beam is included in the first sidelink reservation information of the second terminal.

[0104] For example, the first reserved beam is the same as the beam currently used by the second terminal to transmit the PSSCH and / or the PSCCH, the first terminal can determine the RSRP of the third terminal based on the first reserved beam. That is, the first terminal can determine the RSRP of the third terminal based on the beam currently used by the second terminal to transmit the PSSCH and / or the PSCCH, or the first terminal can determine the RSRP of the third terminal based on the first reserved beam.

[0105] For another example, the first reserved beam is different from the beam currently used by the second terminal to transmit the PSSCH and / or the PSCCH, the first terminal can determine the RSRP of the third terminal based on the beam currently used by the second terminal to transmit the PSSCH and / or the PSCCH. That is, the first terminal can determine the RSRP of the third terminal based on the beam currently used by the second terminal to transmit the PSSCH and / or the PSCCH.

[0106] For another example, the first reserved beam is different from the beam currently used by the second terminal to transmit the PSSCH and / or the PSCCH, the first terminal can determine the RSRP of the third terminal based on the first reserved beam. That is, the first terminal can determine the RSRP of the third terminal based on the first reserved beam.

[0107] It can be understood that if the first reserved beam is the same as the beam currently used by the second terminal to transmit the PSSCH and / or the PSCCH, it is no difference to determine the RSRP of the third terminal based on the beam currently used by the second terminal to transmit the PSSCH and / or the PSCCH or based on the first reserved beam. If the first reserved beam is different from the beam currently used by the second terminal to transmit the PSSCH and / or the PSCCH, it can be selected to determine the RSRP of the third terminal based on the beam currently used by the second terminal to transmit the PSSCH and / or the PSCCH or based on the first reserved beam according to the preset rules or protocol.

[0108] It can be understood that the PSCCH currently transmitted by each terminal refers to the PSCCH corresponding to the SCI containing the corresponding sidelink reservation information, or the PSCCH corresponding to the first-stage SCI when the SCI is the second-stage SCI.

[0109] In addition, the PSSCH currently transmitted by each terminal refers to a PSSCH transmitted on frequency domain resources and time domain resources indicated by SCI containing corresponding sidelink reservation information or a first-stage SCI corresponding to the SCI when the SCI is a second-stage SCI.

[0110] The present disclosure provides a plurality of ways to determine the RSRP of the third terminal, so as to determine whether there is a resource conflict between different terminals performing sidelink transmission, thereby improving the transmission performance based on sidelink transmission.

[0111] In the sidelink resource conflict determination method provided by the embodiments of the present disclosure, the beam of the second terminal can include at least one of the following: a first reserved beam indicated by the first reservation beam information; a beam corresponding to the PSSCH and / or PSCCH transmitted by the second terminal; and omni-directional reception.

[0112] In some embodiments, the beam of the second terminal can include the first reserved beam indicated by the first reservation beam information.

[0113] In some embodiments, the beam of the second terminal can include the beam corresponding to the PSSCH and / or PSCCH transmitted by the second terminal.

[0114] In some embodiments, the beam of the second terminal can include omni-directional reception. The meaning of omni-directional reception is the same as described above, and will not be repeated here.

[0115] In some embodiments, the beam of the second terminal can further include: the first reserved beam indicated by the first reservation beam information, the beam corresponding to the PSSCH and / or PSCCH transmitted by the second terminal; the first reserved beam indicated by the first reservation beam information, omni-directional reception; the beam corresponding to the PSSCH and / or PSCCH transmitted by the second terminal, omni-directional reception; the first reserved beam indicated by the first reservation beam information, the beam corresponding to the PSSCH and / or PSCCH transmitted by the second terminal, and omni-directional reception.

[0116] The present disclosure provides a plurality of forms of the beam of the second terminal for determining the RSRP of different terminals and determining whether there is a resource conflict between different terminals performing sidelink transmission, thereby improving the transmission performance based on sidelink transmission.

[0117] In the sidelink resource conflict determination method provided by the embodiments of the present disclosure, the beam of the third terminal can include at least one of the following: a second reserved beam indicated by the second reservation beam information; a beam corresponding to the PSSCH and / or PSCCH transmitted by the third terminal; and omni-directional reception.

[0118] In some embodiments, the beam of the third terminal can include the second reserved beam indicated by the second reservation beam information.

[0119] In some embodiments, the beam of the third terminal can include a beam through which the third terminal transmits the PSSCH and / or the PSCCH.

[0120] In some embodiments, the beam of the third terminal can include omni-directional reception. The meaning of omni-directional reception is the same as the foregoing, which will not be repeated here.

[0121] In some embodiments, the beam of the third terminal can further include: the second reserved beam indicated by the second reserved beam information, the beam through which the third terminal transmits the PSSCH and / or the PSCCH; the second reserved beam indicated by the second reserved beam information, omni-directional reception; the beam through which the third terminal transmits the PSSCH and / or the PSCCH, omni-directional reception; the second reserved beam indicated by the second reserved beam information, the beam through which the third terminal transmits the PSSCH and / or the PSCCH, omni-directional reception.

[0122] The present disclosure provides various forms of beams of the third terminal for determining the RSRP of different terminals and determining whether there is a resource conflict between different terminals performing sidelink transmission, thereby improving the transmission performance based on sidelink transmission.

[0123] In the sidelink resource conflict determination method provided by the embodiments of the present disclosure, the determination of the resource conflict between the second terminal and the third terminal based on the RSRP of the second terminal and / or the RSRP of the third terminal in S22 includes at least one of the following: in response to the RSRP of the second terminal being greater than or equal to a first RSRP threshold, determining that the second terminal and the third terminal have a resource conflict; in response to the RSRP of the third terminal being greater than or equal to a second RSRP threshold, determining that the second terminal and the third terminal have a resource conflict; and in response to a difference between the RSRP of the second terminal and the RSRP of the third terminal being greater than or equal to a third RSRP threshold, determining that the second terminal and the third terminal have a resource conflict.

[0124] In some embodiments, the first terminal can determine that the second terminal and the third terminal have a resource conflict in response to the RSRP of the second terminal being greater than or equal to the first RSRP threshold.

[0125] For example, when the first terminal is a receiving terminal of the third terminal, or the first terminal is a receiving terminal of both the third terminal and the second terminal, and the priority of the third terminal is higher than the priority of the second terminal (i.e., the priority value of the third terminal is lower than the priority value of the second terminal). The second terminal can be considered as interference, and the third terminal can be considered as a transmitting terminal. In this case, the RSRP of the second terminal is determined, and it is determined whether the RSRP of the second terminal is greater than or equal to the first RSRP threshold. When the RSRP of the second terminal is greater than or equal to the first RSRP threshold, it can be considered that there is a resource conflict between the second terminal and the third terminal.

[0126] It can be understood that the resource conflict mentioned in each embodiment of the present disclosure can also be referred to as resource collision, collision, interference, resource interference, etc.

[0127] The first RSRP threshold can be a protocol-defined or pre-defined RSRP threshold. For example, it can be the same as the RSRP threshold of the traditional omnidirectional (i.e., without considering the beam), or it can be a newly defined RSRP threshold. Of course, if the first RSRP threshold is a newly defined RSRP threshold, it can be an RSRP threshold applicable to all terminals, or it can be defined separately for each priority based on the priority of different terminals. The present disclosure does not limit the setting of the first RSRP threshold. It can be understood that if the RSRP of the second terminal is determined based on the omnidirectional beam, the first RSRP threshold can be the same as the RSRP threshold of the traditional omnidirectional.

[0128] In some embodiments, the first terminal can determine that the second terminal and the third terminal have a resource conflict in response to the RSRP of the third terminal being greater than or equal to the second RSRP threshold.

[0129] For example, when the first terminal is a receiving terminal of the second terminal, or the first terminal is a receiving terminal of the third terminal and a receiving terminal of the second terminal, and the priority of the second terminal is higher than the priority of the third terminal (i.e., the priority value of the second terminal is lower than the priority value of the third terminal). The third terminal can be considered as interference, and the second terminal can be considered as a sending terminal. In this case, the RSRP of the third terminal is determined. And determine whether the RSRP of the third terminal is greater than or equal to the second RSRP threshold. When the RSRP of the third terminal is greater than or equal to the second RSRP threshold, it can be considered that there is a resource conflict between the second terminal and the third terminal.

[0130] The second RSRP threshold can be a protocol-defined or pre-defined RSRP threshold. For example, it can be the same as the RSRP threshold of the traditional omnidirectional (i.e., without considering the beam), or it can be a newly defined RSRP threshold. Of course, if the second RSRP threshold is a newly defined RSRP threshold, it can be an RSRP threshold applicable to all terminals, or it can be defined separately for each priority based on the priority of different terminals. The present disclosure does not limit the setting of the second RSRP threshold. It can be understood that if the RSRP of the third terminal is determined based on the omnidirectional beam, the second RSRP threshold can be the same as the RSRP threshold of the traditional omnidirectional.

[0131] It can be understood that the first RSRP threshold and the second RSRP threshold can be the same or different. For example, if the priorities (or priority values) of the second terminal and the third terminal are different, the first RSRP threshold and the second RSRP threshold are different. For another example, if the priorities (or priority values) of the second terminal and the third terminal are the same, the first RSRP threshold and the second RSRP threshold can be the same.

[0132] In some embodiments, the first terminal can determine that the second terminal and the third terminal exist resource conflict in response to a difference between the RSRP of the second terminal and the RSRP of the third terminal being greater than or equal to a third RSRP threshold.

[0133] For example, the third RSRP threshold can also be referred to as a delta and / or offset threshold, denoted as δ or Δ. When the first terminal is a receiving terminal of the third terminal and a receiving terminal of the second terminal at the same time, the RSRP of the second terminal and the RSRP of the third terminal can be determined. The first terminal can determine which terminal to be a transmitting terminal and which terminal to be an interfering terminal based on the priorities (or priority values) between the second terminal and the third terminal. The interfering terminal can also be referred to as a target terminal, and the transmitting terminal can be a non-target terminal. The first terminal can determine that the RSRP of the target terminal needs to be greater than or equal to the sum of the RSRP of the non-target terminal and the delta. That is, when the RSRP of the target terminal minus the RSRP of the non-target terminal is greater than or equal to the delta, the first terminal determines that the second terminal and the third terminal exist resource conflict.

[0134] For example, when the priority of the second terminal is higher than the priority of the third terminal (i.e., the priority value of the second terminal is lower than the priority value of the third terminal). The third terminal can be an interfering terminal, and the second terminal can be a transmitting terminal. In this case, if it is determined that the RSRP of the third terminal is greater than or equal to the sum of the RSRP of the second terminal and the delta, i.e., the RSRP of the third terminal minus the RSRP of the second terminal is greater than or equal to the delta, it can be determined that the second terminal and the third terminal exist resource conflict.

[0135] For another example, when the priority of the third terminal is higher than the priority of the second terminal (i.e., the priority value of the third terminal is lower than the priority value of the second terminal). The second terminal can be an interfering terminal, and the third terminal can be a transmitting terminal. In this case, if it is determined that the RSRP of the second terminal is greater than or equal to the sum of the RSRP of the third terminal and the delta, i.e., the RSRP of the second terminal minus the RSRP of the third terminal is greater than or equal to the delta, it can be determined that the second terminal and the third terminal exist resource conflict.

[0136] For example, when the first terminal is the receiving terminal of the second terminal, the RSRP of the second terminal and the RSRP of the third terminal can be determined, and the second terminal can be determined as the interference terminal. In this case, if the RSRP of the second terminal is greater than or equal to the sum of the RSRP of the third terminal and delta, i.e., the RSRP of the second terminal minus the RSRP of the third terminal is greater than or equal to delta, it can be determined that the second terminal and the third terminal have resource conflicts.

[0137] For example, when the first terminal is the receiving terminal of the second terminal, the RSRP of the second terminal and the RSRP of the third terminal can be determined, and the second terminal can be determined as the interference terminal. In this case, if the RSRP of the second terminal is greater than or equal to the sum of the RSRP of the third terminal and delta, i.e., the RSRP of the second terminal minus the RSRP of the third terminal is greater than or equal to delta, it can be determined that the second terminal and the third terminal have resource conflicts.

[0138] Of course, the above embodiment describes the delta as the third RSRP threshold, and in other embodiments, the offset threshold can be used instead, and the disclosure is not limited.

[0139] The delta and / or offset threshold can be specified in the protocol or predefined. For example, it can be the same as the RSRP threshold of the conventional omnidirectional (i.e., without considering the beam), or it can be a newly defined RSRP threshold, and the disclosure does not limit the setting of the delta and / or offset threshold. It can be understood that if the RSRP of the second terminal and / or the RSRP of the third terminal is determined based on omnidirectional reception, the delta and / or offset threshold can be the same as the RSRP threshold of the conventional omnidirectional. In addition, the value of the delta and / or offset threshold when the first terminal is the receiving terminal of the second terminal, and the value of the delta and / or offset threshold when the first terminal is the receiving terminal of the third terminal can be the same or different.

[0140] The disclosure provides a variety of ways to determine resource conflicts, and uses the RSRP of different terminals to determine whether there is a resource conflict between different terminals for sidelink transmission, which improves the transmission performance based on sidelink transmission.

[0141] The specific condition includes at least one of the following: the first reservation resource information and the second reservation resource information overlap in a time domain; the first reservation resource information and the second reservation resource information overlap in a frequency domain; the first reserved beam indicated by the first reservation beam information overlaps with the second reserved beam indicated by the second reservation beam information; the first reserved beam indicated by the first reservation beam information does not overlap with the second reserved beam indicated by the second reservation beam information, and the first terminal is a receiving terminal of the second terminal or the first terminal is a receiving terminal of the third terminal; the first reserved beam indicated by the first reservation beam information does not overlap with the second reserved beam indicated by the second reservation beam information, and the first terminal is a receiving terminal of the second terminal and the third terminal, and the first terminal cannot simultaneously receive the first reserved beam indicated by the first reservation beam information and the second reserved beam indicated by the second reservation beam information.

[0142] In some embodiments, the specific condition satisfied by the first sidelink reservation information and the second sidelink reservation information can include that the first reservation resource information and the second reservation resource information overlap in a time domain.

[0143] For example, if the first reservation resource information and the second reservation resource information overlap in a time domain, the RSRP of the second terminal and / or the RSRP of the third terminal can be determined.

[0144] In some embodiments, the specific condition satisfied by the first sidelink reservation information and the second sidelink reservation information can include that the first reservation resource information and the second reservation resource information overlap in a frequency domain.

[0145] For example, if the first reservation resource information and the second reservation resource information overlap in a frequency domain, the RSRP of the second terminal and / or the RSRP of the third terminal can be determined.

[0146] In some embodiments, the specific condition satisfied by the first sidelink reservation information and the second sidelink reservation information can include that the first reserved beam indicated by the first reservation beam information overlaps with the second reserved beam indicated by the second reservation beam information.

[0147] It can be understood that the meaning of the beam overlapping includes that the first terminal needs to use the same transmission beam or reception beam to transmit or receive the channels and / or signals corresponding to the transmission of the first reserved beam and the second reserved beam. It can also include that the first reserved beam and the second reserved beam overlap in part of the range.

[0148] For example, if the first reserved beam indicated by the first reservation beam information overlaps with the second reserved beam indicated by the second reservation beam information, the RSRP of the second terminal and / or the RSRP of the third terminal can be determined.

[0149] In some embodiments, the specific condition that the first sidelink reservation information and the second sidelink reservation information satisfy can comprise that the first reservation beam indicated by the first reservation beam information and the second reservation beam indicated by the second reservation beam information do not overlap, and the first terminal is a receiving terminal of the second terminal or the first terminal is a receiving terminal of the third terminal.

[0150] It can be understood that the meaning of the beams not overlapping includes that the first terminal needs to use different transmission beams or reception beams to transmit or receive the channels and / or signals corresponding to the transmission of the first reservation beam and the second reservation beam. It can also include that the first reservation beam and the second reservation beam do not overlap in range.

[0151] For example, if the first reservation beam indicated by the first reservation beam information and the second reservation beam indicated by the second reservation beam information do not overlap, and the first terminal is a receiving terminal of the second terminal, or the first terminal is a receiving terminal of the third terminal, the RSRP of the second terminal and / or the RSRP of the third terminal can be determined. It should be understood that even if the beams do not overlap, there can be interference between different terminals.

[0152] In some embodiments, the specific condition that the first sidelink reservation information and the second sidelink reservation information satisfy can comprise that the first reservation beam indicated by the first reservation beam information and the second reservation beam indicated by the second reservation beam information do not overlap, and the first terminal is a receiving terminal of the second terminal and the third terminal, and the first terminal cannot simultaneously receive the first reservation beam indicated by the first reservation beam information and the second reservation beam indicated by the second reservation beam information.

[0153] For example, if the first reservation beam indicated by the first reservation beam information and the second reservation beam indicated by the second reservation beam information do not overlap, and the first terminal is a receiving terminal of the second terminal and the third terminal, and the first terminal cannot simultaneously receive the first reservation beam indicated by the first reservation beam information and the second reservation beam indicated by the second reservation beam information, the RSRP of the second terminal and / or the RSRP of the third terminal can be determined.

[0154] The condition of being unable to simultaneously receive includes that the first terminal has only one antenna panel, and the first reservation beam and the second reservation beam are not included in the range of one reception beam of the first terminal. If the first terminal has only one antenna panel, but the first reservation beam and the second reservation beam are included in the range of one reception beam of the first terminal, the first terminal can simultaneously receive the first reservation beam and the second reservation beam. Or, if the first terminal has multiple antenna panels, the first terminal can also simultaneously receive the first reservation beam and the second reservation beam using different antenna panels.

[0155] It can be understood that in the case that the first terminal cannot simultaneously receive the first reserved beam indicated by the first reserved beam information and the second reserved beam indicated by the second reserved beam information, the first terminal can determine to receive the terminal with higher priority (i.e., the terminal with lower priority value) according to the priorities (or priority values) of the second terminal and the third terminal.

[0156] Of course, if the first terminal can simultaneously receive the first reserved beam indicated by the first reserved beam information and the second reserved beam indicated by the second reserved beam information, there is no need to determine the RSRP of the second terminal and the RSRP of the third terminal.

[0157] In some embodiments, the specific condition satisfied by the first sidelink reservation information and the second sidelink reservation information can further include:

[0158] The first reserved resource information and the second reserved resource information have time domain overlap; the first reserved resource information and the second reserved resource information have frequency domain overlap. The first reserved beam information indicates that the first reserved beam and the second reserved beam indicated by the second reserved beam information have overlap; the first reserved beam information indicates that the first reserved beam and the second reserved beam indicated by the second reserved beam information have no overlap, and the first terminal is a receiving terminal of the second terminal or the first terminal is a receiving terminal of the third terminal; the first reserved beam information indicates that the first reserved beam and the second reserved beam indicated by the second reserved beam information have no overlap, and the first terminal is a receiving terminal of the second terminal and the third terminal, and the first terminal cannot simultaneously receive the first reserved beam indicated by the first reserved beam information and the second reserved beam indicated by the second reserved beam information. The first reserved resource information and the second reserved resource information have time domain overlap; the first reserved resource information and the second reserved resource information have frequency domain overlap; the first reserved beam information indicates that the first reserved beam and the second reserved beam indicated by the second reserved beam information have overlap; the first reserved beam information indicates that the first reserved beam and the second reserved beam indicated by the second reserved beam information have no overlap, and the first terminal is a receiving terminal of the second terminal or the first terminal is a receiving terminal of the third terminal. The first reserved resource information and the second reserved resource information have time domain overlap; the first reserved resource information and the second reserved resource information have frequency domain overlap; the first reserved beam information indicates that the first reserved beam and the second reserved beam indicated by the second reserved beam information have overlap; the first reserved beam information indicates that the first reserved beam and the second reserved beam indicated by the second reserved beam information have no overlap, and the first terminal is a receiving terminal of the second terminal or the first terminal is a receiving terminal of the third terminal; the first reserved beam information indicates that the first reserved beam and the second reserved beam indicated by the second reserved beam information have no overlap, and the first terminal is a receiving terminal of the second terminal and the third terminal, and the first terminal cannot simultaneously receive the first reserved beam indicated by the first reserved beam information and the second reserved beam indicated by the second reserved beam information.

[0159] It can be understood that the specific conditions can also include any two, three, four, or five of the above, and the present disclosure will not be listed one by one.

[0160] The present disclosure provides a plurality of cases of specific conditions, which are suitable for determining the RSRP of different terminals in different cases, and determining whether there is a resource conflict between different terminals performing sidelink transmission, thereby improving the transmission performance based on sidelink transmission.

[0161] In the sidelink resource conflict determination method provided by the embodiments of the present disclosure, the method can further include: sending resource conflict information to the second terminal or the third terminal, the resource conflict information being used to indicate reselection of the reserved resource and / or the reserved beam.

[0162] In some embodiments, the first terminal can send resource conflict information to the second terminal or the third terminal in a case where it is determined that there is a resource conflict between the second terminal and the third terminal. The resource conflict information is used to indicate reselection of the reserved resource and / or the reserved beam.

[0163] The reserved resource can be a first reserved resource indicated by the first reserved resource information of the second terminal and / or a second reserved resource indicated by the second reserved resource information of the third terminal. The reserved beam can be a first reserved beam indicated by the first reserved beam information of the second terminal and / or a second reserved beam indicated by the second reserved beam information of the third terminal.

[0164] For example, in a case where it is determined that the second terminal is an interference terminal or the priority of the second terminal is lower than the priority of the third terminal (i.e., the priority value of the second terminal is higher than the priority value of the third terminal) and there is a resource conflict between the second terminal and the third terminal, the first terminal can send resource conflict information to the second terminal. The second terminal can reselect the first reserved resource indicated by the first reserved resource information and / or the first reserved beam indicated by the first reserved beam information based on the resource conflict information. For example, the second terminal can reselect only the first reserved resource, or only the first reserved beam, or both the first reserved resource and the first reserved beam.

[0165] It can be understood that the second terminal reselects resources other than the first reserved resource and / or the first reserved beam when reselecting.

[0166] For example, in a case where it is determined that the third terminal is an interference terminal or the priority of the third terminal is lower than the priority of the second terminal (i.e., the priority value of the third terminal is higher than the priority value of the second terminal) and there is a resource conflict between the second terminal and the third terminal, the first terminal can send resource conflict information to the third terminal. The third terminal can reselect the second reserved resource indicated by the second reserved resource information and / or the second reserved beam indicated by the second reserved beam information based on the resource conflict information. For example, the third terminal can reselect only the second reserved resource, or only the second reserved beam, or both the second reserved resource and the second reserved beam.

[0167] It can be understood that the third terminal reselects resources other than the second reserved resource and / or the second reserved beam when reselecting.

[0168] The present disclosure can also reselect resources in a case where there is a resource conflict, thereby improving the transmission performance based on sidelink transmission.

[0234] Of course, the specific configuration of each SCI can refer to the description in the related art, and the present disclosure will not be repeated.

[0235] The present disclosure can transmit reservation information and / or resource conflict information through multiple types of SCI to determine whether there is a resource conflict between different terminals performing sidelink transmission, thereby improving the transmission performance based on sidelink transmission.

[0236] Based on the same concept, the present disclosure also provides a sidelink resource conflict determination method applied by a second terminal or a third terminal.

[0237] Figure 4 is another sidelink resource conflict determination method flowchart according to an exemplary embodiment, as Figure 4 As shown in the figure, the method is performed by a terminal, which can be a second terminal or a third terminal. The method can include the following steps:

[0238] In step S31, in response to the terminal being a second terminal, first sidelink reservation information is sent to the first terminal; in response to the terminal being a third terminal, second sidelink reservation information is sent to the first terminal.

[0239] In some embodiments, in response to the terminal being a second terminal, the second terminal can send first sidelink reservation information to the first terminal.

[0240] In some embodiments, in response to the terminal being a third terminal, the third terminal can send second sidelink reservation information to the first terminal.

[0241] The first sidelink reservation information and the second sidelink reservation information are used by the first terminal to determine that the second terminal and the third terminal have a resource conflict. The first sidelink reservation information includes first reservation resource information and / or first reservation beam information; the second sidelink reservation information includes second reservation resource information and / or second reservation beam information.

[0242] And, the first reservation resource information corresponds to the first reservation beam information, that is, the transmission of the channel and / or signal on the first reservation resource indicated by the first reservation resource information will be based on the beam indicated by the first reservation beam information; the second reservation resource information corresponds to the second reservation beam information, that is, the transmission of the channel and / or signal on the second reservation resource indicated by the second reservation resource information will be based on the beam indicated by the second reservation beam information.

[0243] For example, the first sidelink reservation information includes the first reservation resource information and the first reservation beam information, and the second sidelink reservation information includes the second reservation resource information and the second reservation beam information.

[0244] For another example, the first sidelink reservation information can include one of the first reservation resource information and the first reservation beam information, and the second sidelink reservation information includes the second reservation resource information and the second reservation beam information.

[0245] For another example, the first sidelink reservation information includes the first reservation resource information and the first reservation beam information, and the second sidelink reservation information can include one of the second reservation resource information and the second reservation beam information.

[0246] For another example, the first sidelink reservation information can include one of the first reservation resource information and the first reservation beam information, and the second sidelink reservation information can include one of the second reservation resource information and the second reservation beam information.

[0247] Wherein, the channel and / or signal transmitted on the first reservation resource and / or the second reservation resource can include at least one of the following: PSSCH; PSCCH; PSFCH; PSBCH; S-SS / PSBCH Block; sidelink CSI-RS; sidelink DMRS; sidelink PT-RS.

[0248] It can be understood that the first sidelink reservation information can be the relevant resource reserved by the second terminal for sidelink transmission. For example, it includes the first reservation resource information and the first reservation beam information. The second sidelink reservation information can be the relevant resource reserved by the third terminal for sidelink transmission. For example, it includes the second reservation resource information and the second reservation beam information.

[0249] Wherein, the first reservation resource information is used to indicate the first reservation resource reserved by the second terminal for sidelink communication. The first reservation beam information is used to indicate the first reservation beam reserved by the second terminal for sidelink communication. The first reservation resource information corresponds to the first reservation beam information, that is, the second terminal performs sidelink communication on the first reservation resource through the first reservation beam.

[0250] The second reserved resource information is used to indicate a second reserved resource reserved by the third terminal for sidelink communication. The second reserved beam information is used to indicate a second reserved beam reserved by the third terminal for sidelink communication. The second reserved resource information corresponds to the second reserved beam information, that is, the third terminal performs sidelink communication on the second reserved resource through the second reserved beam.

[0251] In some embodiments, the first reserved beam and / or the second reserved beam mentioned above can be indicated by at least one of the following: sidelink spatial relation information; sidelink spatial setting; sidelink spatial RX parameter; sidelink Tx spatial filter; sidelink spatial domain receive filter; sidelink spatial domain transmission filter; sidelink TCI state; sidelink QCL typeD.

[0252] Meanwhile, the beam identifier corresponding to the first reserved beam and / or the second reserved beam mentioned above can include at least one of the following: sidelink CSI-RS resource identifier; S-SS / PSBCH Block identifier; slot identifier corresponding to the reference signal resource; mini-slot identifier corresponding to the reference signal resource. It can be understood that the reference signal indicated by the reference signal identifier mentioned above has a QCL relationship with the channel / signal transmitted on the corresponding reserved resource. For example, the reference signal indicated by the reference signal identifier included in the first reserved beam has a QCL relationship with the channel / signal transmitted on the first reserved resource. For another example, the reference signal indicated by the reference signal identifier included in the second reserved beam has a QCL relationship with the channel / signal transmitted on the second reserved resource.

[0253] Of course, in some embodiments, the second terminal can also send the first sidelink reservation information to the network device, and the network device sends the first sidelink reservation information to the first terminal. And / or, the third terminal can also send the second sidelink reservation information to the network device, and the network device sends the first sidelink reservation information to the first terminal.

[0254] It can be understood that the first terminal and the second terminal will perform sidelink communication based on the first reserved resource and / or the first reserved beam indicated by the first sidelink reservation information, and / or the first terminal and the third terminal will perform sidelink communication based on the second reserved resource and / or the second reserved beam indicated by the second sidelink reservation information.

[0255] The disclosure determines whether there is a resource conflict between different terminals performing sidelink transmission by obtaining sidelink reservation resources reserved by other terminals, thereby improving transmission performance based on sidelink transmission.

[0256] In the sidelink resource conflict determination method provided by the embodiments of the disclosure, the determination that the second terminal and the third terminal have a resource conflict can be implemented in the following manner: in response to the first sidelink reservation information and the second sidelink reservation information satisfying a specific condition, the RSRP of the second terminal and / or the RSRP of the third terminal are used to determine that the second terminal and the third terminal have a resource conflict.

[0257] In some embodiments, in response to the first sidelink reservation information and the second sidelink reservation information satisfying a specific condition, the first terminal can determine the RSRP of the second terminal and / or the RSRP of the third terminal.

[0258] In some embodiments, the determination of one or more of the RSRP of the second terminal and the RSRP of the third terminal by the first terminal can depend on which terminal the first terminal is a receiving terminal for and how the first terminal determines whether there is a resource conflict between the second terminal and the third terminal based on the RSRP.

[0259] For example, if the first terminal is concerned about comparing the RSRP of an interfering terminal with a corresponding threshold to determine whether there is a resource conflict, the first terminal can determine the RSRP of the interfering terminal. The interfering terminal refers to a terminal that is not a receiving terminal for the first terminal, and for the first terminal, this terminal is an interfering terminal.

[0260] For example, in response to the first terminal being a receiving terminal for the third terminal, the RSRP of the second terminal is determined.

[0261] For example, the first terminal is a receiving terminal for the third terminal, that is, when the first terminal and the third terminal perform sidelink communication, the first terminal receives sidelink data and the third terminal transmits sidelink data. Then the RSRP of the second terminal can be determined. It can be understood that since the first terminal is a receiving terminal for the third terminal, the first terminal should consider the interference caused by the second terminal to the first terminal. Therefore, the first terminal needs to consider the interference caused by the channel and / or signal transmitted by the second terminal to the first terminal.

[0262] It can be understood that the first terminal being a receiving terminal for the third terminal means that the first terminal is a receiving terminal for the third terminal on the second reservation resource and / or the second reservation beam.

[0263] For another example, in response to the first terminal being a receiving terminal for the second terminal, the RSRP of the third terminal is determined.

[0264] For example, the first terminal is a receiving terminal of the second terminal, i.e., the first terminal receives sidelink data and the second terminal transmits sidelink data when the first terminal and the second terminal perform sidelink communication. Then the RSRP of the third terminal can be determined. It can be understood that since the first terminal is a receiving terminal of the second terminal, the first terminal should consider the interference brought by the third terminal to the first terminal. Therefore, the first terminal needs to consider the interference brought by the channel and / or signal transmitted by the third terminal to the first terminal.

[0265] It can be understood that the first terminal being a receiving terminal of the second terminal means that the first terminal is a receiving terminal of the second terminal on the first reserved resource and / or the first reserved beam.

[0266] For another example, in response to the first terminal being a receiving terminal of the second terminal and a receiving terminal of the third terminal, the RSRP of the terminal with a higher priority value between the second terminal and the third terminal is determined, wherein the higher the priority value, the lower the priority of the corresponding terminal.

[0267] For example, if the first terminal is a receiving terminal of the second terminal and a receiving terminal of the third terminal. Then the first terminal can determine which terminal of the second terminal and the third terminal has a higher priority, and the terminal with a higher priority is taken as a transmitting terminal and the terminal with a lower priority is taken as an interfering terminal. Wherein the priority can be determined based on the priority value, and the higher the priority value of the terminal, the lower the priority of the terminal. Therefore, the higher the priority value of the terminal, the lower the priority of the terminal, and the terminal is taken as an interfering terminal. Conversely, the lower the priority value of the terminal, the higher the priority of the terminal, and the terminal is taken as a transmitting terminal.

[0268] For example, if the priority value of the second terminal is higher than the priority value of the third terminal, it means that the priority of the second terminal is lower than the priority of the third terminal. Therefore, the second terminal is taken as an interfering terminal and the third terminal is taken as a transmitting terminal.

[0269] For another example, if the first terminal focuses on the offset between the RSRP of the interfering terminal and the RSRP of the transmitting terminal, such as comparing the offset with a corresponding threshold to determine whether there is a resource conflict between the second terminal and the third terminal, the first terminal needs to determine the RSRP of the interfering terminal and the RSRP of the transmitting terminal.

[0270] For example, in response to the first terminal being a receiving terminal of the second terminal and the third terminal being an interfering terminal, the first terminal needs to determine the offset between the RSRP of the interfering terminal and the RSRP of the transmitting terminal, and determine whether there is a resource conflict between the second terminal and the third terminal based on the relationship between the offset and the corresponding threshold. Then the first terminal can determine the RSRP of the second terminal and the RSRP of the third terminal.

[0271] For another example, in response to the first terminal being a receiving terminal of the third terminal, the second terminal is an interfering terminal. The first terminal needs to determine the offset between the RSRP of the interfering terminal and the RSRP of the sending terminal, and determine whether there is a resource conflict between the second terminal and the third terminal based on the relationship between the offset and the corresponding threshold. Then the first terminal can determine the RSRP of the second terminal and the RSRP of the third terminal at the same time.

[0272] For another example, in response to the first terminal being a receiving terminal of the second terminal and a receiving terminal of the third terminal, one of the second terminal and the third terminal is an interfering terminal, and the other is a sending terminal. The first terminal needs to determine the offset between the RSRP of the interfering terminal and the RSRP of the sending terminal, and determine whether there is a resource conflict between the second terminal and the third terminal based on the relationship between the offset and the corresponding threshold. Then the first terminal can determine the RSRP of the second terminal and the RSRP of the third terminal at the same time.

[0273] It can be understood that in this case, which of the second terminal and the third terminal is an interfering terminal and which is a sending terminal. It can be determined according to the priority size (or priority value size) of the second terminal and the third terminal. For example, the terminal with higher priority (i.e., lower priority value) is the sending terminal, and the other terminal is the interfering terminal.

[0274] In some embodiments, based on the RSRP of the second terminal and / or the RSRP of the third terminal, the first terminal can determine that there is a resource conflict between the second terminal and the third terminal.

[0275] For example, the first terminal can determine, based on the RSRP of the second terminal and / or the RSRP of the third terminal, that there is a resource conflict between the second terminal and the third terminal. For another example, the first terminal can determine, based on the RSRP of the second terminal and / or the RSRP of the third terminal, that there is no resource conflict between the second terminal and the third terminal.

[0276] The present disclosure determines the RSRP of the corresponding terminal by obtaining the sidelink reserved resource reserved by the other terminal under certain conditions, to determine whether there is a resource conflict between different terminals performing sidelink transmission, thereby improving the transmission performance based on sidelink transmission.

[0277] In the sidelink resource conflict determination method provided by the embodiments of the present disclosure, the RSRP of the second terminal can be determined by determining the RSRP of the second terminal based on the beam of the third terminal or the beam of the second terminal.

[0278] In some embodiments, the first terminal can determine the RSRP of the second terminal based on the beam of the third terminal or the beam of the second terminal. It should be noted that the RSRP of the second terminal includes the RSRP obtained based on the measurement of the PSSCH and / or PSCCH transmitted by the second terminal.

[0279] For example, the first terminal can determine the RSRP of the second terminal based on the beam of the second terminal. Wherein the first reservation beam information is included in the first sidelink reservation information of the second terminal, and the first reservation beam information is used to indicate the first reservation beam.

[0280] For example, if the first reservation beam is the same as the beam currently used by the second terminal to transmit the PSSCH and / or PSCCH, the first terminal can determine the RSRP of the second terminal based on the first reservation beam. That is, the first terminal can determine the RSRP of the second terminal based on the beam currently used by the second terminal to transmit the PSSCH and / or PSCCH, or the first terminal can determine the RSRP of the second terminal based on the first reservation beam.

[0281] For another example, if the first reservation beam is different from the beam currently used by the second terminal to transmit the PSSCH and / or PSCCH, the first terminal can determine the RSRP of the second terminal based on the beam currently used by the second terminal to transmit the PSSCH and / or PSCCH. That is, the first terminal can determine the RSRP of the second terminal based on the beam currently used by the second terminal to transmit the PSSCH and / or PSCCH.

[0282] For another example, if the first reservation beam is different from the beam currently used by the second terminal to transmit the PSSCH and / or PSCCH, the first terminal can determine the RSRP of the second terminal based on the first reservation beam. That is, the first terminal can determine the RSRP of the second terminal based on the first reservation beam.

[0283] It can be understood that if the first reservation beam is the same as the beam currently used by the second terminal to transmit the PSSCH and / or PSCCH, it is indifferent to determine the RSRP of the second terminal based on the beam currently used by the second terminal to transmit the PSSCH and / or PSCCH or based on the first reservation beam. If the first reservation beam is different from the beam currently used by the second terminal to transmit the PSSCH and / or PSCCH, it can be selected to determine the RSRP of the second terminal based on the beam currently used by the second terminal to transmit the PSSCH and / or PSCCH or based on the first reservation beam according to a preset rule or protocol.

[0284] For another example, the first terminal can also determine the RSRP of the second terminal based on omni-directional reception. It can be understood that the omni-directional reception is opposite to the beam-based reception. The beam-based reception refers to the reception with a relatively clear directionality, and the reception range is small and only targets the corresponding range indicated by the beam. The omni-directional reception refers to the reception without the beam, i.e., the reception direction range is large, such as the omni-direction.

[0285] For another example, the first terminal determines the RSRP of the second terminal based on the beam of the third terminal. The second reservation beam information is included in the second sidelink reservation information of the third terminal, and the second reservation beam information is used to indicate the second reservation beam.

[0286] For example, the second reservation beam is the same as the beam currently used by the third terminal to transmit the PSSCH and / or PSCCH, and the first terminal can determine the RSRP of the second terminal based on the second reservation beam. That is, the first terminal can determine the RSRP of the second terminal based on the beam currently used by the third terminal to transmit the PSSCH and / or PSCCH, or the first terminal can determine the RSRP of the second terminal based on the second reservation beam.

[0287] For another example, the second reservation beam is different from the beam currently used by the third terminal to transmit the PSSCH and / or PSCCH, and the first terminal can determine the RSRP of the second terminal based on the beam currently used by the third terminal to transmit the PSSCH and / or PSCCH. That is, the first terminal can determine the RSRP of the second terminal based on the beam currently used by the third terminal to transmit the PSSCH and / or PSCCH.

[0288] For another example, the second reservation beam is different from the beam currently used by the third terminal to transmit the PSSCH and / or PSCCH, and the first terminal can determine the RSRP of the second terminal based on the second reservation beam. That is, the first terminal can determine the RSRP of the second terminal based on the second reservation beam.

[0289] It can be understood that if the second reservation beam is the same as the beam currently used by the third terminal to transmit the PSSCH and / or PSCCH, it is no difference to determine the RSRP of the second terminal based on the beam currently used by the third terminal to transmit the PSSCH and / or PSCCH or based on the second reservation beam. If the second reservation beam is different from the beam currently used by the third terminal to transmit the PSSCH and / or PSCCH, it can be selected to determine the RSRP of the second terminal based on the beam currently used by the third terminal to transmit the PSSCH and / or PSCCH or based on the second reservation beam according to the preset rules or protocol.

[0290] It can be understood that the PSCCH currently transmitted by each terminal refers to the PSCCH corresponding to the SCI containing the corresponding sidelink reservation information, or the PSCCH corresponding to the first-stage SCI corresponding to the second-stage SCI.

[0291] In addition, the PSSCH currently transmitted by each terminal refers to the PSSCH transmitted on the frequency domain resource and the time domain resource indicated by the SCI containing the corresponding sidelink reservation information or the first-stage SCI corresponding to the second-stage SCI.

[0292] The present disclosure provides a plurality of ways to determine the RSRP of the second terminal, so as to determine whether there is a resource conflict between different terminals performing sidelink transmission, thereby improving the transmission performance based on sidelink transmission.

[0293] In the sidelink resource conflict determination method provided by the embodiments of the present disclosure, the RSRP of the third terminal can be determined in the following manner: determining the RSRP of the third terminal based on the beam of the second terminal or the beam of the third terminal.

[0294] In some embodiments, the first terminal can determine the RSRP of the third terminal based on the beam of the second terminal or the beam of the third terminal. It should be noted that the RSRP of the third terminal includes the RSRP obtained by measuring the PSSCH and / or PSCCH transmitted by the third terminal.

[0295] For example, the first terminal determines the RSRP of the third terminal based on the beam of the third terminal. The second sidelink reservation information of the third terminal includes second reservation beam information, and the second reservation beam information is used to indicate the second reservation beam.

[0296] For example, the second reservation beam is the same as the beam of the PSSCH or PSCCH currently transmitted by the third terminal, and the first terminal can determine the RSRP of the third terminal based on the second reservation beam. That is, the first terminal can determine the RSRP of the third terminal based on the beam of the PSSCH and / or PSCCH currently transmitted by the third terminal, or the first terminal can determine the RSRP of the third terminal based on the second reservation beam.

[0297] For another example, the second reservation beam is different from the beam of the PSSCH and / or PSCCH currently transmitted by the third terminal, and the first terminal can determine the RSRP of the third terminal based on the beam of the PSSCH and / or PSCCH currently transmitted by the third terminal. That is, the first terminal can determine the RSRP of the third terminal based on the beam of the PSSCH and / or PSCCH currently transmitted by the third terminal.

[0298] For example, the first terminal can determine the RSRP of the third terminal based on the first reserved beam. That is, the first terminal can determine the RSRP of the third terminal based on the beam on which the second terminal currently transmits the PSSCH and / or the PSCCH.

[0299] It can be understood that, if the second reserved beam is the same as the beam on which the third terminal currently transmits the PSSCH and / or the PSCCH, it is indifferent whether the RSRP of the third terminal is determined based on the beam on which the third terminal currently transmits the PSSCH and / or the PSCCH or based on the second reserved beam. If the second reserved beam is different from the beam on which the third terminal currently transmits the PSSCH and / or the PSCCH, the RSRP of the third terminal can be determined based on the beam on which the third terminal currently transmits the PSSCH and / or the PSCCH or based on the second reserved beam according to a preset rule or protocol.

[0300] For example, the first terminal can also determine the RSRP of the third terminal based on omnidirectional reception. It can be understood that the omnidirectional reception is opposite to the beam reception. The beam reception refers to reception with a relatively clear direction, a small reception range, and only for the corresponding range indicated by the beam. The omnidirectional reception refers to reception without the beam, that is, a large range of reception direction, such as omnidirectional.

[0301] For example, the first terminal determines the RSRP of the third terminal based on the beam of the second terminal. The first reserved beam information in the first sidelink reservation information of the second terminal includes the second reserved beam information, and the second reserved beam information is used to indicate the second reserved beam.

[0302] For example, the first reserved beam is the same as the beam on which the second terminal currently transmits the PSSCH and / or the PSCCH, the first terminal can determine the RSRP of the third terminal based on the first reserved beam. That is, the first terminal can determine the RSRP of the third terminal based on the beam on which the second terminal currently transmits the PSSCH and / or the PSCCH, or the first terminal can determine the RSRP of the third terminal based on the first reserved beam.

[0303] For example, the first reserved beam is different from the beam on which the second terminal currently transmits the PSSCH and / or the PSCCH, the first terminal can determine the RSRP of the third terminal based on the beam on which the second terminal currently transmits the PSSCH and / or the PSCCH. That is, the first terminal can determine the RSRP of the third terminal based on the beam on which the second terminal currently transmits the PSSCH and / or the PSCCH.

[0304] For example, if the first reserved beam is different from the beam currently used by the second terminal to transmit the PSSCH and / or PSCCH, the first terminal can determine the RSRP of the third terminal based on the first reserved beam. That is, the first terminal can determine the RSRP of the third terminal based on the first reserved beam.

[0305] It can be understood that if the first reserved beam is the same as the beam currently used by the second terminal to transmit the PSSCH and / or PSCCH, it makes no difference whether the RSRP of the third terminal is determined based on the beam currently used by the second terminal to transmit the PSSCH and / or PSCCH or based on the first reserved beam. If the first reserved beam is different from the beam currently used by the second terminal to transmit the PSSCH and / or PSCCH, the RSRP of the third terminal can be determined based on the beam currently used by the second terminal to transmit the PSSCH and / or PSCCH or based on the first reserved beam according to a preset rule or protocol.

[0306] It can be understood that the PSCCH currently transmitted by each terminal refers to the PSCCH corresponding to the SCI containing the corresponding sidelink reservation information, or the PSCCH corresponding to the first-stage SCI corresponding to the second-stage SCI.

[0307] In addition, the PSSCH currently transmitted by each terminal refers to the PSSCH transmitted on the frequency domain resources and time domain resources indicated by the SCI containing the corresponding sidelink reservation information or the first-stage SCI corresponding to the second-stage SCI.

[0308] The present disclosure provides various ways to determine the RSRP of the third terminal, so as to determine whether there is a resource conflict between different terminals performing sidelink transmission, thereby improving the transmission performance based on sidelink transmission.

[0309] In the sidelink resource conflict determination method provided by the embodiments of the present disclosure, the beam of the second terminal can include at least one of the following: the first reserved beam indicated by the first reserved beam information; the beam currently used by the second terminal to transmit the PSSCH and / or PSCCH; and omni-directional reception.

[0310] In some embodiments, the beam of the second terminal can include the first reserved beam indicated by the first reserved beam information.

[0311] In some embodiments, the beam of the second terminal can include the beam currently used by the second terminal to transmit the PSSCH and / or PSCCH.

[0312] In some embodiments, the beam of the second terminal can include omni-directional reception. The meaning of omni-directional reception is the same as described above, and will not be repeated here.

[0313] In some embodiments, the beam of the second terminal can further include: the first reserved beam indicated by the first reserved beam information, the beam corresponding to the sending of the PSSCH and / or the PSCCH by the second terminal; the first reserved beam indicated by the first reserved beam information, omni-directional reception; the beam corresponding to the sending of the PSSCH and / or the PSCCH by the second terminal, omni-directional reception; the first reserved beam indicated by the first reserved beam information, the beam corresponding to the sending of the PSSCH and / or the PSCCH by the second terminal, omni-directional reception.

[0314] The present disclosure provides multiple forms of beams of the second terminal for determining the RSRP of different terminals and determining whether there is a resource conflict between different terminals performing sidelink transmission, thereby improving the transmission performance based on sidelink transmission.

[0316] In some embodiments, the beam of the third terminal can include the second reserved beam indicated by the second reserved beam information.

[0317] In some embodiments, the beam of the third terminal can include the beam corresponding to the sending of the PSSCH and / or the PSCCH by the third terminal.

[0318] In some embodiments, the beam of the third terminal can include omni-directional reception. The meaning of omni-directional reception is the same as the foregoing, and will not be described here again.

[0319] In some embodiments, the beam of the third terminal can further include: the second reserved beam indicated by the second reserved beam information, the beam corresponding to the sending of the PSSCH and / or the PSCCH by the third terminal; the second reserved beam indicated by the second reserved beam information, omni-directional reception; the beam corresponding to the sending of the PSSCH and / or the PSCCH by the third terminal, omni-directional reception; the second reserved beam indicated by the second reserved beam information, the beam corresponding to the sending of the PSSCH and / or the PSCCH by the third terminal, omni-directional reception.

[0320] The present disclosure provides multiple forms of beams of the third terminal for determining the RSRP of different terminals and determining whether there is a resource conflict between different terminals performing sidelink transmission, thereby improving the transmission performance based on sidelink transmission.

[0321] In the sidelink resource conflict determination method provided by the embodiments of the present disclosure, the determination that the second terminal and the third terminal have resource conflict can be achieved in at least one of the following manners: in response to the RSRP of the second terminal being greater than or equal to the first RSRP threshold, it is determined that the second terminal and the third terminal have resource conflict; in response to the RSRP of the third terminal being greater than or equal to the second RSRP threshold, it is determined that the second terminal and the third terminal have resource conflict; in response to the difference between the RSRP of the second terminal and the RSRP of the third terminal being greater than or equal to the third RSRP threshold, it is determined that the second terminal and the third terminal have resource conflict.

[0322] In some embodiments, in response to the RSRP of the second terminal being greater than or equal to the first RSRP threshold, the first terminal can determine that the second terminal and the third terminal have resource conflict.

[0323] For example, when the first terminal is a receiving terminal of the third terminal, or the first terminal is a receiving terminal of the third terminal and a receiving terminal of the second terminal, and the priority of the third terminal is higher than the priority of the second terminal (i.e., the priority value of the third terminal is lower than the priority value of the second terminal). The second terminal can be considered as interference, and the third terminal can be considered as a sending terminal. In this case, the RSRP of the second terminal is determined, and it is determined whether the RSRP of the second terminal is greater than or equal to the first RSRP threshold. When the RSRP of the second terminal is greater than or equal to the first RSRP threshold, it can be considered that there is resource conflict between the second terminal and the third terminal.

[0324] It can be understood that the resource conflict mentioned in the embodiments of the present disclosure can also be referred to as resource collision, collision, interference, resource interference, etc.

[0325] The first RSRP threshold can be specified or predefined in a protocol. For example, it can be the same as the RSRP threshold of the traditional omnidirectional (i.e., without considering the beam), or it can be a newly defined RSRP threshold. Of course, if the first RSRP threshold is a newly defined RSRP threshold, it can be an RSRP threshold applicable to all terminals, or it can be defined separately for each priority based on the priority of different terminals. The present disclosure does not limit the setting of the first RSRP threshold. It can be understood that if the RSRP of the second terminal is determined based on the omnidirectional beam, the first RSRP threshold can be the same as the RSRP threshold of the traditional omnidirectional.

[0326] In some embodiments, in response to the RSRP of the third terminal being greater than or equal to the second RSRP threshold, the first terminal can determine that the second terminal and the third terminal have resource conflict.

[0327] For example, when the first terminal is a receiving terminal of the second terminal, or the first terminal is a receiving terminal of the third terminal and a receiving terminal of the second terminal, and the priority of the second terminal is higher than the priority of the third terminal (i.e., the priority value of the second terminal is lower than the priority value of the third terminal). The third terminal can be considered as interference, and the second terminal can be considered as a sending terminal. In this case, the RSRP of the third terminal is determined. It is determined whether the RSRP of the third terminal is greater than or equal to the second RSRP threshold value. When the RSRP of the third terminal is greater than or equal to the second RSRP threshold value, it can be considered that there is a resource conflict between the second terminal and the third terminal.

[0328] The second RSRP threshold value can be specified in a protocol or predefined. For example, it can be the same as the RSRP threshold value of the conventional omnidirectional (i.e., without considering the beam), or it can be a newly defined RSRP threshold value. Of course, if the second RSRP threshold value is a newly defined RSRP threshold value, it can be an RSRP threshold value applicable to all terminals, or it can be defined separately for each priority based on the priority of different terminals. The disclosure does not limit the setting of the second RSRP threshold value. It can be understood that if the RSRP of the third terminal is determined based on the omnidirectional beam, the second RSRP threshold value can be the same as the RSRP threshold value of the conventional omnidirectional.

[0329] It can be understood that the first RSRP threshold value and the second RSRP threshold value can be the same or different. For example, if the priorities (or priority values) of the second terminal and the third terminal are different, the first RSRP threshold value and the second RSRP threshold value are different. For example, if the priorities (or priority values) of the second terminal and the third terminal are the same, the first RSRP threshold value and the second RSRP threshold value can be the same.

[0330] In some embodiments, in response to the difference between the RSRP of the second terminal and the RSRP of the third terminal being greater than or equal to the third RSRP threshold value, the first terminal can determine that the second terminal and the third terminal have a resource conflict.

[0331] For example, the third RSRP threshold can also be referred to as a delta and / or offset threshold, denoted as δ or Δ. When the first terminal is both a receiving terminal of the third terminal and a receiving terminal of the second terminal, the RSRP of the second terminal and the RSRP of the third terminal can be determined. The first terminal can determine which terminal to be a transmitting terminal and which terminal to be an interfering terminal based on the priority (or priority value) between the second terminal and the third terminal. The interfering terminal can also be referred to as a target terminal, and the transmitting terminal can be a non-target terminal. The first terminal can determine that the RSRP of the target terminal needs to be greater than or equal to the sum of the RSRP of the non-target terminal and the delta. That is, when the RSRP of the target terminal minus the RSRP of the non-target terminal is greater than or equal to the delta, the first terminal determines that there is a resource conflict between the second terminal and the third terminal.

[0332] For example, when the priority of the second terminal is higher than the priority of the third terminal (i.e., the priority value of the second terminal is lower than the priority value of the third terminal). The third terminal can be an interfering terminal, and the second terminal can be a transmitting terminal. In this case, if it is determined that the RSRP of the third terminal is greater than or equal to the sum of the RSRP of the second terminal and the delta, i.e., the RSRP of the third terminal minus the RSRP of the second terminal is greater than or equal to the delta, it can be determined that there is a resource conflict between the second terminal and the third terminal.

[0333] For example, when the priority of the third terminal is higher than the priority of the second terminal (i.e., the priority value of the third terminal is lower than the priority value of the second terminal). The second terminal can be an interfering terminal, and the third terminal can be a transmitting terminal. In this case, if it is determined that the RSRP of the second terminal is greater than or equal to the sum of the RSRP of the third terminal and the delta, i.e., the RSRP of the second terminal minus the RSRP of the third terminal is greater than or equal to the delta, it can be determined that there is a resource conflict between the second terminal and the third terminal.

[0334] For example, when the first terminal is both a receiving terminal of the third terminal and a receiving terminal of the second terminal, the RSRP of the second terminal and the RSRP of the third terminal can be determined, and the second terminal can be determined to be an interfering terminal. In this case, if it is determined that the RSRP of the second terminal is greater than or equal to the sum of the RSRP of the third terminal and the delta, i.e., the RSRP of the second terminal minus the RSRP of the third terminal is greater than or equal to the delta, it can be determined that there is a resource conflict between the second terminal and the third terminal.

[0335] For another example, when the first terminal is a receiving terminal of the second terminal, the RSRP of the second terminal and the RSRP of the third terminal can be determined, and it is determined that the third terminal is an interference terminal. In this case, if it is determined that the RSRP of the third terminal is greater than or equal to the sum of the RSRP of the second terminal and delta, that is, the RSRP of the third terminal minus the RSRP of the second terminal is greater than or equal to delta, it can be determined that the second terminal and the third terminal have resource conflicts.

[0336] Of course, the above embodiment describes that the delta is used as the third RSRP threshold, and in other embodiments, the offset threshold can be used instead, which is not limited in the present disclosure.

[0337] The delta and / or offset threshold can be specified in a protocol or predefined. For example, it can be the same as the RSRP threshold of the conventional omnidirectional (that is, without considering the beam), or it can be a newly defined RSRP threshold, and the present disclosure does not limit the setting of the delta and / or offset threshold. It can be understood that if the RSRP of the second terminal and / or the RSRP of the third terminal is determined based on omnidirectional reception, the delta and / or offset threshold can be the same as the RSRP threshold of the conventional omnidirectional. In addition, the value of the delta and / or offset threshold when the first terminal is a receiving terminal of the second terminal, and the value of the delta and / or offset threshold when the first terminal is a receiving terminal of the third terminal can be the same or different.

[0338] The present disclosure provides a variety of ways to determine whether there is a resource conflict between different terminals for sidelink transmission, and whether there is a resource conflict between different terminals for sidelink transmission is determined by the RSRP of the different terminals, thereby improving the transmission performance based on sidelink transmission.

[0339] In the sidelink resource conflict determination method provided by the embodiment of the present disclosure, the specific condition includes at least one of the following: the first reservation resource information and the second reservation resource information have time domain overlap; the first reservation resource information and the second reservation resource information have frequency domain overlap; the first reservation beam information indicates that the first reservation beam and the second reservation beam information indicates that the second reservation beam have overlap; the first reservation beam information indicates that the first reservation beam and the second reservation beam information indicates that the second reservation beam do not have overlap, and the first terminal is a receiving terminal of the second terminal or the first terminal is a receiving terminal of the third terminal; the first reservation beam information indicates that the first reservation beam and the second reservation beam information indicates that the second reservation beam do not have overlap, and the first terminal is a receiving terminal of the second terminal and the third terminal, and the first terminal cannot simultaneously receive the first reservation beam information indicates that the first reservation beam and the second reservation beam information indicates that the second reservation beam.

[0340] In some embodiments, the specific condition satisfied by the first sidelink reservation information and the second sidelink reservation information can comprise that the first reservation resource information and the second reservation resource information have a time domain overlap.

[0341] For example, if the first reservation resource information and the second reservation resource information have a time domain overlap, the RSRP of the second terminal and / or the RSRP of the third terminal can be determined.

[0342] In some embodiments, the specific condition satisfied by the first sidelink reservation information and the second sidelink reservation information can comprise that the first reservation resource information and the second reservation resource information have a frequency domain overlap.

[0343] For example, if the first reservation resource information and the second reservation resource information have a frequency domain overlap, the RSRP of the second terminal and / or the RSRP of the third terminal can be determined.

[0344] In some embodiments, the specific condition satisfied by the first sidelink reservation information and the second sidelink reservation information can comprise that the first reservation beam information indicates that the first reservation beam and the second reservation beam information indicates that the second reservation beam have an overlap.

[0345] It can be understood that the meaning of the overlap of the beams comprises that the first terminal needs to use the same transmission beam or reception beam to transmit or receive the channels and / or signals corresponding to the transmissions of the first reservation beam and the second reservation beam. It can also comprise that the first reservation beam and the second reservation beam have a partial range overlap.

[0346] For example, if the first reservation beam information indicates that the first reservation beam and the second reservation beam information indicates that the second reservation beam have an overlap, the RSRP of the second terminal and / or the RSRP of the third terminal can be determined.

[0347] In some embodiments, the specific condition satisfied by the first sidelink reservation information and the second sidelink reservation information can comprise that the first reservation beam information indicates that the first reservation beam and the second reservation beam information indicates that the second reservation beam have no overlap, and the first terminal is a reception terminal of the second terminal or the first terminal is a reception terminal of the third terminal.

[0348] It can be understood that the meaning of the non-overlap of the beams comprises that the first terminal needs to use different transmission beams or reception beams to transmit or receive the channels and / or signals corresponding to the transmissions of the first reservation beam and the second reservation beam. It can also comprise that the first reservation beam and the second reservation beam have no range overlap.

[0349] For example, if the first reserved beam indicated by the first reserved beam information does not overlap with the second reserved beam indicated by the second reserved beam information, and the first terminal is a receiving terminal of the second terminal or a receiving terminal of the third terminal, the RSRP of the second terminal and / or the RSRP of the third terminal can be determined. It should be understood that even if the beams do not overlap, there can be a case of interference between different terminals.

[0350] In some embodiments, the specific condition that the first sidelink reservation information and the second sidelink reservation information satisfy can include that the first reserved beam indicated by the first reserved beam information does not overlap with the second reserved beam indicated by the second reserved beam information, and the first terminal is a receiving terminal of the second terminal and the third terminal, and the first terminal cannot simultaneously receive the first reserved beam indicated by the first reserved beam information and the second reserved beam indicated by the second reserved beam information.

[0351] For example, if the first reserved beam indicated by the first reserved beam information does not overlap with the second reserved beam indicated by the second reserved beam information, and the first terminal is a receiving terminal of the second terminal and the third terminal, and the first terminal cannot simultaneously receive the first reserved beam indicated by the first reserved beam information and the second reserved beam indicated by the second reserved beam information, the RSRP of the second terminal and / or the RSRP of the third terminal can be determined.

[0352] Wherein, the case of being unable to simultaneously receive includes that the first terminal has only one antenna panel, and the first reserved beam and the second reserved beam are not included in the one receiving beam range of the first terminal. If the first terminal has only one antenna panel, but the first reserved beam and the second reserved beam are included in the one receiving beam range of the first terminal, the first terminal can simultaneously receive the first reserved beam and the second reserved beam. Or, if the first terminal has multiple antenna panels, the first terminal can also simultaneously receive the first reserved beam and the second reserved beam by using different antenna panels.

[0353] It can be understood that in the case that the first terminal cannot simultaneously receive the first reserved beam indicated by the first reserved beam information and the second reserved beam indicated by the second reserved beam information, the first terminal can determine the terminal with higher receiving priority (i.e., the terminal with lower priority value) according to the priority (or priority value) of the second terminal and the third terminal.

[0354] Of course, if the first terminal can simultaneously receive the first reserved beam indicated by the first reserved beam information and the second reserved beam indicated by the second reserved beam information, there is no need to determine the RSRP of the second terminal and the RSRP of the third terminal.

[0355] In some embodiments, the specific condition satisfied by the first sidelink reservation information and the second sidelink reservation information can further include:

[0356] The first reservation resource information and the second reservation resource information have a time domain overlap; the first reservation resource information and the second reservation resource information have a frequency domain overlap. The first reservation beam information indicates that the first reservation beam and the second reservation beam indicated by the second reservation beam information have an overlap; the first reservation beam information indicates that the first reservation beam and the second reservation beam indicated by the second reservation beam information have no overlap, and the first terminal is a receiving terminal of the second terminal or the first terminal is a receiving terminal of the third terminal; the first reservation beam information indicates that the first reservation beam and the second reservation beam indicated by the second reservation beam information have no overlap, and the first terminal is a receiving terminal of the second terminal and the third terminal, and the first terminal cannot simultaneously receive the first reservation beam indicated by the first reservation beam information and the second reservation beam indicated by the second reservation beam information. The first reservation resource information and the second reservation resource information have a time domain overlap; the first reservation resource information and the second reservation resource information have a frequency domain overlap; the first reservation beam information indicates that the first reservation beam and the second reservation beam indicated by the second reservation beam information have an overlap; the first reservation beam information indicates that the first reservation beam and the second reservation beam indicated by the second reservation beam information have no overlap, and the first terminal is a receiving terminal of the second terminal or the first terminal is a receiving terminal of the third terminal. The first reservation resource information and the second reservation resource information have a time domain overlap; the first reservation resource information and the second reservation resource information have a frequency domain overlap; the first reservation beam information indicates that the first reservation beam and the second reservation beam indicated by the second reservation beam information have an overlap; the first reservation beam information indicates that the first reservation beam and the second reservation beam indicated by the second reservation beam information have no overlap, and the first terminal is a receiving terminal of the second terminal or the first terminal is a receiving terminal of the third terminal; the first reservation beam information indicates that the first reservation beam and the second reservation beam indicated by the second reservation beam information have no overlap, and the first terminal is a receiving terminal of the second terminal and the third terminal, and the first terminal cannot simultaneously receive the first reservation beam indicated by the first reservation beam information and the second reservation beam indicated by the second reservation beam information.

[0357] It can be understood that the specific condition can further include any two, three, four, or five of the above, and the disclosure will not be listed one by one.

[0358] The disclosure provides a plurality of cases of the specific condition, which is suitable for determining the RSRP of different terminals in different cases, and determining whether there is a resource conflict between different terminals performing sidelink transmission, thereby improving the transmission performance based on sidelink transmission.

[0359] In the sidelink resource conflict determination method provided by the embodiments of the disclosure, Figure 5is another method flowchart for sidelink resource collision determination according to an example embodiment. As shown in Figure 5 The method can further include the following steps:

[0360] In step S41, the resource collision information sent by the first terminal is received.

[0361] In some embodiments, the resource collision information sent by the first terminal can be received by the terminal whether it is the second terminal or the third terminal.

[0362] In step S42, the reserved resources and / or reserved beams are reselected based on the resource collision information.

[0363] In some embodiments, the terminal can reselect the reserved resources and / or reserved beams of the terminal itself based on the resource collision information received in S41.

[0364] The reserved resources can be the first reserved resources indicated by the first reserved resource information of the second terminal, and / or the second reserved resources indicated by the second reserved resource information of the third terminal. The reserved beams can be the first reserved beams indicated by the first reserved beam information of the second terminal, and / or the second reserved beams indicated by the second reserved beam information of the third terminal.

[0365] For example, if the terminal is the second terminal, the second terminal can receive the resource collision information sent by the first terminal. The second terminal can reselect the first reserved resources indicated by the first reserved resource information and / or the first reserved beams indicated by the first reserved beam information based on the resource collision information. For example, the second terminal only reselects the first reserved resources, or only reselects the first reserved beams, or reselects both the first reserved resources and the first reserved beams.

[0366] It can be understood that when the second terminal reselects, it reselects resources other than the first reserved resources and / or the first reserved beams.

[0367] For example, if the terminal is the third terminal, the third terminal can receive the resource collision information sent by the first terminal. The third terminal can reselect the second reserved resources indicated by the second reserved resource information and / or the second reserved beams indicated by the second reserved beam information based on the resource collision information. For example, the third terminal only reselects the second reserved resources, or only reselects the second reserved beams, or reselects both the second reserved resources and the second reserved beams.

[0368] It can be understood that when the third terminal reselects, it reselects resources other than the second reserved resources and / or the second reserved beams.

[0369] The present disclosure can also reselect resources in the presence of resource collisions, improving the transmission performance based on sidelink transmission.
