[0002] The 5G New Radio (NR) system can support higher data rates and lower latency. In order to ensure system performance, the relevant technology mainly obtains and maintains a set of optimal beams for uplink and downlink transmissions through beam management, thereby ensuring the precise alignment of the transmit / receive beams required for directional links. At present, the beam management process involved in the 5G NR system mainly involves beam scanning, beam measurement, beam selection, and beam reporting, and its implementation process is determined by the terminal and network-side equipment (i.e., base stations, etc.).

[0003] However, for the sidelink (SL) scenario, SL transmission is determined by the terminal, which makes the relevant beam management process proposed in the 5G NR system not applicable to the SL scenario. Therefore, how to implement beam management in the SL scenario is still a technical problem that needs to be solved urgently in this field. Summary of the invention

[0029] Understandably, Figure 1 The communication between the terminals 11 described in is SL communication.

[0030] The technical solution provided by the embodiments of the present application is described in detail below through some embodiments and their application scenarios in combination with the accompanying drawings.

[0031] like Figure 2 As shown, it is a flowchart of a beam management method 200 provided by an exemplary embodiment of the present application. The method 200 can be, but is not limited to, executed by a first terminal, and can be specifically executed by hardware or software installed in the first terminal. In this embodiment, the method 200 can at least include the following steps.

[0032] S210: The first terminal determines a first transmission according to a measurement or demodulation result of a first reference signal.

[0033] Among them, the first reference signal can be sent by the second terminal based on the SL between the second terminal and the first terminal to implement beam management, such as beam failure detection, beam failure recovery, beam switching, beam update, etc. Optionally, the first reference signal can be but is not limited to a radio link monitoring (Radio Link Monitoring, RLM) reference signal (Reference Signal, RS), a beam failure detection (Beam Failure Detection, BFD) RS, a signal state information reference signal (Channel State Information-Reference Signal, CSI-RS), a synchronization signal block (Synchronization Signal and PBCH block, SSB), etc.

[0034] Based on this, in one implementation, the beam quality, beam identification, whether the wireless link fails, etc. of the receiving beam can be measured according to the measurement or demodulation result, and no limitation is made here. That is to say, in this embodiment, the first transmission determined based on the measurement or demodulation result of the first reference signal can be used for beam management. For example, in this embodiment, depending on the type of the beam management, the information carried in the first transmission may be different, such as the first transmission may carry a beam failure recovery request (Beam Failure Recovery Request, BFRQ), beam switching information, channel state information (CSI) reporting information, UE collaboration information (or UE recommendation information), data information, etc., and no limitation is made here.

[0035] Of course, in this embodiment, the first transmission can be SL physical random access channel (Physical Random Access Channel, PRACH), physical sidelink shared channel (Physical Sidelink Shared Channel, PSSCH), physical sidelink feedback channel (Physical Sidelink Feedback Channel, PSFCH), sidelink control information (Sidelink Control Information, SCI), medium access control element (Medium Access Control Control Element, MAC CE), etc., without limitation here.

[0036] S220: Send the first transmission to the second terminal based on the first resource.

[0037] Among them, considering that the first resource is used for sending the first transmission, then, in this embodiment, there may be multiple ways to determine the first resource, such as, the first resource may be determined by one or more of the following ways, such as protocol pre-definition, network configuration, terminal configuration, and determination based on the first reference signal. In this embodiment, the determination of the first resource is achieved in the aforementioned way, so that when the first terminal sends the first transmission to the second terminal, the second terminal and the first terminal have a consistent understanding of the resources used for sending the first transmission, so that the second terminal can correctly receive the first transmission for beam management, such as beam failure recovery, beam update, beam switching, etc., so as to ensure communication quality.

[0038] Optionally, the aforementioned network configuration may be a network pre-configuration or may be configured through signaling, etc., which is not limited here. In addition, the terminal configuration may be a first terminal configuration or a second terminal configuration. For example, when the first terminal performs the configuration, the first terminal may notify the second terminal of the determination method of the first resource to ensure that the two have a consistent understanding of the determination method of the first resource.

[0039] In this case, in one implementation method, when one or more first resources are determined by one or more of the aforementioned protocol predefinition, network configuration, terminal configuration, determination based on the first reference signal, etc., the first terminal may be directly configured with the first resources, or may be configured with a first resource set including at least one of the first resources, or may be configured with a second resource set, in which one or more of the first resource sets are configured, that is, the first resource set is a subset of the second resource set, and no limitation is made here.

[0040] It should be noted that, for the situation where the first terminal is configured with the first resource set and the first resource set includes at least one first resource, the first resource set satisfies but is not limited to at least one of the following (11)-(13).

[0041] (11) The first resource set is a periodic resource set, that is, the first resource set is defined or configured according to a configured period of the first resource set.

[0042] (12) Different first resource sets are used for sending the first transmission in different triggering processes.

[0043] Among them, the triggering process can be understood as the process of triggering the first transmission to be sent, such as the initial access process, the beam failure recovery process, the beam update process, etc., which is not limited here.

[0044] In this embodiment, assuming that multiple first resource sets are configured, such as resource set A1, resource set A2, and resource set A3, then resource set A1, resource set A2, and resource set A3 can be used for sending the first transmission in different triggering processes, respectively.

[0045] (13) A plurality of resource subsets are configured in the same first resource set, and different resource subsets are used for sending the first transmission in different triggering processes.

[0046] Among them, similar to (12), the triggering process can be understood as the process of triggering the first transmission to be sent, such as the initial access process, the beam failure recovery process, the beam update process, etc., which is not limited here.

[0047] In this embodiment, it is assumed that a first resource set is configured, and the first resource set includes multiple resource subsets, such as resource subset B1, resource subset B2, and resource subset B3. Then, resource subset B1, resource subset B2, and resource subset B3 can be used respectively for sending the first transmission in different trigger processes.

[0048] Of course, for the aforementioned first resource, it can be at least one of time domain resources (such as time slot, symbol, etc.), frequency domain resources (such as physical resource blocks (PRB), subchannels, interlace resources), and code domain resources (such as sequences, orthogonal cover codes (OCC), orthogonal cyclic shifts).

[0049] In this case, considering that the second terminal and the first terminal have the same or corresponding understanding of the first resource (or the method of determining the first resource), the second terminal can correctly receive the first transmission sent by the first terminal based on the first resource, and then perform beam management according to the first transmission, such as beam switching, beam updating, beam failure detection, beam failure recovery, etc., to ensure the beam quality in the SL scenario.

[0050] In this embodiment, in SL, the first terminal determines the first transmission based on the measurement or demodulation result of the first reference signal, and then sends the first transmission to the second terminal based on the first resource. Thus, sending the first transmission through the first resource can ensure that the second terminal can correctly receive the first transmission, so as to realize beam management on SL and further ensure beam quality.

[0051] like Figure 3As shown, it is a flowchart of a beam management method 300 provided by an exemplary embodiment of the present application. The method 300 can be, but is not limited to, executed by a first terminal, and can be specifically executed by hardware or software installed in the first terminal. In this embodiment, the method 300 can at least include the following steps.

[0052] S310: The first terminal determines a first transmission according to a measurement or demodulation result of a first reference signal.

[0053] Wherein, wherein the first transmission is used for beam management.

[0054] S320: Send the first transmission to the second terminal based on the first resource.

[0055] It can be understood that in addition to referring to the relevant description in the aforementioned method embodiment 200, the implementation process of S310-S320, as a possible implementation method, assumes that the first resource is determined according to the first reference signal, then the first terminal can determine the first resource according to the first reference signal and a preset association relationship; wherein the preset association relationship is configured with an association relationship between each transmission resource and each first object, wherein the first object includes a measurement reference signal (such as SSB, CSI RS, BFD RS, Candidate Beam Detection (CBD) RS, etc.) or a beam corresponding to the measurement reference signal (such as a beam used for receiving a first reference signal, etc.).

[0056] For example, assuming that the preset association relationship configures an association relationship between each transmission resource and each measurement reference signal, then the first terminal can directly determine the transmission resource associated with the first reference signal based on the preset association relationship and send the first transmission.

[0057] For another example, assuming that the preset association relationship is configured with an association relationship between each transmission resource and the beam corresponding to each measurement reference signal, then the first terminal can directly determine the transmission resource associated with the beam corresponding to the first reference signal based on the preset association relationship, and send the first transmission.

[0058] Of course, there are many ways to configure the aforementioned preset association relationship, such as protocol agreement, network configuration, terminal configuration, etc. Based on this, in one implementation, the configuration process of the preset association relationship may include but is not limited to: numbering multiple first objects, and mapping each of the numbered first objects to each of the transmission resources according to the order of each of the transmission resources.

[0059] When numbering the plurality of first objects, the numbering method may include but is not limited to at least one of the following (21)-(22).

[0060] (21) Numbering each of the first objects according to the index size of the first object (such as ascending or descending order).

[0061] For example, when the first object is a measurement reference signal, the index of the measurement reference signal may be determined according to a mapping relationship between the measurement reference signal and a beam index.

[0062] (22) Numbering the first objects according to an index size (such as ascending or descending order) of a resource unit where the first objects are located, where the resource unit includes a time domain unit or a frequency domain unit.

[0063] Among them, the resource unit where the first object is located can be but is not limited to a time domain resource unit, a frequency domain resource unit, etc. For example, assuming that the resource unit where the first object is located includes both a time domain resource unit and a frequency domain resource unit, the first object can be numbered first according to the ascending / descending order of the index of the frequency domain resource (such as PRB, subchannel, interlace) where the first object is located, and then numbered according to the ascending / descending order of the time domain resource unit (such as slot, symbol) where the first object is located; or, the time domain resource unit where the first object is located can be numbered first, and then according to the ascending / descending order of the PRB where the object is located, and there is no limitation here.

[0064] It should be noted that when numbering according to the ascending / descending order of the time domain resource unit (such as slot, symbol) where the first object is located, symbol may be numbered first and then slot, and this embodiment does not impose any limitation thereto.

[0065] In one implementation, the index of the resource unit where the aforementioned first object is located can be determined according to at least one of the following (31)-(32).

[0066] (31) When the first object is located in a resource pool, the index of the resource unit where the first object is located is determined according to the logical index of each resource in the resource pool. It can be understood that the resource pool mentioned in the context of this embodiment is an SL resource pool, which may include SL-related resources, such as PSSCH, PSCCH, PSFCH, measurement reference signal, etc.

[0067] (32) When the first object is located outside the resource pool, determine the index of the resource unit where the first object is located according to the physical index of each resource.

[0068] Accordingly, in the configuration process of the aforementioned preset association relationship, the order of each transmission resource is determined differently according to the type of the transmission resource. For example, when the transmission resource is a time domain resource, it can be sorted in ascending or descending order according to the index of the resource unit corresponding to the time domain resource, such as first sorting in ascending / descending order of the symbol where the transmission resource is located, and then sorting in ascending / descending order of the slot where the transmission resource is located.

[0069] For another example, when the transmission resources are frequency domain resources, they may be sorted in ascending / descending order according to the indexes of resource units (such as PRB, subchannel, interlace) corresponding to the frequency domain resources.

[0070] For another example, when the transmission resource is a code domain resource, the code domain resource may be sorted in ascending / descending order according to the index of the resource unit corresponding to the code domain resource (such as a sequence of the code domain resource, OCC, orthogonal cyclic code).

[0071] Of course, it should be noted that when determining the order of the transmission resources, the order of the transmission resources can also be determined based on the relationship between the first object, the transmission resources and the resource pool. For example, in this embodiment, the determination method may include but is not limited to at least one of the following (41)-(44).

[0072] (41) When the first object is located in a resource pool, the order of the resource units where the transmission resources are located is determined according to the logical index of each resource in the resource pool.

[0073] (42) When the first object is located outside the resource pool, determine the order of the resource units where the transmission resources are located according to the physical index of each resource.

[0074] (43) When the plurality of transmission resources are located in the same resource pool, the order of the resource units in which the resources are located is determined according to the logical index of each resource.

[0075] (44) When the plurality of transmission resources are located in different resource pools, the order of the resource units in which the resources are located is determined according to the physical index of each resource.

[0076] In one implementation, the transmission resource associated with the first object satisfies at least one of the following (51)-(55).

[0077] (51) The time domain interval between the transmission resource and the first object is greater than a preset value.

[0078] Among them, when there are multiple transmission resources associated with the first object, then the transmission resource whose time domain interval with the first object is greater than a preset value can be the Kth (for example, the first) of the multiple transmission resources.

[0079] It is worth noting that if the transmission resource with a time domain interval greater than a preset value with respect to the first object can be the Kth transmission resource among multiple transmission resources corresponding to another first object, then the transmission resource corresponding to the first object can be the K+1th transmission resource among multiple transmission resources that satisfy the above time domain interval, and so on. For example, assuming that the first object is a beam, and the transmission resources (such as time domain resource positions) of beam 1, beam 2, and beam 3 that satisfy the above time interval are all slot Z, slot Z+2, and slot Z+4, then beam 1 corresponds to slot Z, beam 2 corresponds to slot Z+2, and beam 3 corresponds to slot Z+4. Wherein, Z is an integer greater than or equal to 1.

[0080] (52) The time domain position of the transmission resource is associated with the index of the first object.

[0081] (53) The transmission resource is associated with the time domain resource unit (such as the starting time domain resource unit) where the first object is located.

[0082] (54) The frequency domain position or code domain position of the transmission resource is associated with the index of the first object.

[0083] (55) The frequency domain position or code domain position of the transmission resource is associated with the frequency domain resource unit (such as the starting frequency domain resource unit) where the first object is located.

[0084] For example, the frequency domain position of the transmission resource associated with the first object is (beam ID / index) mod L, where L is the number of frequency domain resources included in one of the transmission resources.

[0085] It is worth noting that in this embodiment, through the restrictions on the transmission resources that have an association relationship with the first object in the aforementioned (51)-(55), when the first terminal and the second terminal send and receive the first transmission based on the preset association relationship, they can have a consistent understanding of the first transmission, thereby correctly sending and receiving the first transmission.

[0086] In another implementation, the resource pool where the first resource associated with the first object is located includes at least one of the following (61)-(65).

[0087] (61) A resource pool including the first object and the transmission resource associated with the first object. In other words, the first object and the transmission resource associated with the first object are located in the same resource pool.

[0088] (62) The Nth resource pool after the resource or resource pool where the first object is located and having transmission resources associated with the first object, where N is an integer greater than or equal to 1.

[0089] (63) A resource pool having a transmission resource associated with the first object after the resource or resource pool where the first object is located, wherein a first time interval is satisfied between the transmission resource and the first object associated therewith, thereby satisfying the processing capacity of the terminal. The first time interval and the second time interval mentioned later may be implemented by protocol agreement, network configuration, etc., and are not limited here.

[0090] It is worth noting that the transmission resources associated with multiple first objects are located in the same resource pool, which means that after determining the resource pool where the transmission resources associated with the first first object are located, the subsequent first object also determines the transmission resources associated with it in this resource pool.

[0091] Of course, in addition to the aforementioned transmission resources associated with the multiple first objects being located in the same resource pool, they may also be located in different resource pools, which is not limited here.

[0092] (64) A resource pool having transmission resources associated with a plurality of the first objects, wherein a second time interval is satisfied between the plurality of the first objects and the transmission resources associated with them, thereby satisfying the processing capacity of the terminal.

[0093] (65) Specific resource pool. The specific resource pool may be determined by protocol pre-definition, network configuration or indication, terminal configuration, negotiation between the first terminal and the second terminal, etc., which is not limited here.

[0094] It is worth noting that in this embodiment, the restrictions on the resource pool where the first resource associated with the first object is located in the aforementioned (61)-(65) can, on the one hand, enable the first terminal and the second terminal to have a consistent understanding of the first transmission when sending and receiving the first transmission based on the preset association relationship, thereby correctly sending and receiving the first transmission. On the other hand, it can also meet the processing capabilities of the terminals and ensure the reliability of the first transmission.

[0095] In one implementation, when configuring the aforementioned preset association relationship, the preset association relationship can be configured based on an association period to improve the flexibility and efficiency of the preset association relationship configuration. In this embodiment, when an association period is configured, the first object can be associated with at least one transmission resource within the association period at least once, wherein the association period includes at least one configuration period for configuring the third resource set, and the third resource set includes at least one of the transmission resources. It should be noted that the aforementioned first resource set belongs to at least one of the third resource sets.

[0096] In addition, within an association cycle, after mapping multiple first objects to at least one transmission resource at least once, if a group of transmission resources is insufficient to map the multiple first objects, then the group of transmission resources may not map the first objects.

[0097] In another implementation, when there are multiple association cycles, M (M is an integer greater than or equal to 1) association cycles among the multiple association cycles are used to send a third transmission, and the remaining association cycles are used to monitor a fourth transmission, and the third transmission includes the first transmission. Thus, the half-duplex problem of SL transmission (such as PSFCH, etc.) existing in the related technology can be avoided, thereby improving communication efficiency.

[0098] For example, when the multiple association cycles are within a specific time, the third transmission can be sent based on M association cycles among the multiple association cycles, and the remaining other association cycles are used to monitor the fourth transmission, wherein the specific time is the time where the transmission resource is located, such as the time window where the transmission resource is located or the time lower limit.

[0099] It is worth noting that in this embodiment, as a possible implementation method, there may be a corresponding relationship between the time unit where the first object is located and the time unit where the transmission resource is located, that is, the first terminal sends the first transmission within a specific time after receiving the first reference signal to ensure that the second terminal can receive the first transmission.

[0100] Based on this, for the aforementioned association period, when the first terminal determines the first resource according to the first reference signal and the preset association relationship, it can determine the target association period from the configured multiple association periods according to the terminal identifier of the first terminal, and then determine the first resource according to the first reference signal and the preset association relationship corresponding to the target association period. It can be understood that the preset association relationship is based on the target association period configuration, so that before determining the first resource, the target association period is first determined, and the first resource is determined based on the preset association relationship corresponding to the target association period, which can improve the efficiency and accuracy of determining the first resource.

[0101] Of course, when the first reference signal has a preset association relationship with multiple transmission resources, the first resource can be selected from multiple transmission resources according to at least one of the following (71)-(73), thereby avoiding transmission (such as PSFCH) conflicts and ensuring communication quality.

[0102] (71) Random selection.

[0103] (72) Selection is performed based on the terminal identifier, such as selecting a first resource associated with the terminal identifier, etc., which is not limited here.

[0104] (73) Selecting a resource unit where the first reference signal is located, such as selecting a transmission resource whose interval with the resource unit where the first reference signal is located meets a predetermined value as the first resource, etc., which is not limited here.

[0105] It is worth noting that the first terminal and the second terminal have the same understanding of the association relationship or the method of determining the association relationship between the aforementioned first object and the transmission resource, thereby ensuring that the first terminal and the second terminal can realize the sending and receiving of the first transmission.

[0106] In addition, in this embodiment, in order to improve transmission reliability and transmission efficiency, in one implementation, the process of the first terminal sending the first transmission to the second terminal based on the first resource may also include at least one of the following (81)-(85).

[0107] (81) Sending the first transmission based on the first resource and a preset transmission pattern, thereby avoiding a half-duplex transmission and reception problem of the first transmission.

[0108] The preset transmission pattern may be determined according to a time domain pattern or a bitmap of time domain resources.

[0109] Optionally, in this embodiment, when multiple preset transmission patterns are configured, the first terminal may randomly select a preset transmission pattern for the first transmission, or determine the preset transmission pattern for the first transmission according to a terminal identifier, etc., which is not limited here.

[0110] In addition, in one implementation, different transmission patterns may be used to send (or monitor) the first transmission for different terminals. For example, assuming that three transmission patterns (such as P1, P2, and P3) are defined for the terminal to send (or monitor) the first transmission, then UE1 may use P1 to send the first transmission and use P2 and P3 to monitor the first transmission, UE2 may use P2 to send the first transmission and use P1 and P3 to monitor the first transmission, and so on. No limitation is made here.

[0111] (82) The first transmission is sent based on the first resource and using a beam scanning method, thereby determining the transmission beam of the first transmission so that the second terminal can correctly receive the first transmission.

[0112] (83) The first transmission is transmitted based on the first resource and using a first default beam, thereby determining a transmission beam of the first transmission so that the second terminal can correctly receive the first transmission.

[0113] The default beam is determined by protocol pre-definition, network configuration or indication, terminal configuration or indication, negotiation between the first terminal and the second terminal, etc. For example, the first default beam may be, but is not limited to, a wide beam used for initial access.

[0114] (84) Based on the first resource, a first transmission is sent using a first beam or a beam pair, wherein the first beam or the beam pair corresponds to a beam used to receive the first reference signal. Thus, by determining the transmission beam of the first transmission, the second terminal can correctly receive the first transmission.

[0115] (85) Based on the first resource, a first transmission is transmitted using a second beam or a beam pair, wherein the second beam or a beam pair is a beam or a beam pair maintained between the first terminal and the second terminal (assuming that the transmit and receive beams of the first terminal do not have a beam correspondence relationship). Thus, by determining the transmit beam of the first transmission, the second terminal can correctly receive the first transmission.

[0116] In one implementation, when the first terminal sends a first transmission to the second terminal based on the first resource, if the first condition is met, the first transmission may be sent to the second terminal based on the first resource and a preset priority rule to ensure communication quality. The preset priority rule defines the priority order of SL transmissions carrying different information, for example, the priority of the first transmission carrying BFRQ is higher than the priority of the first transmission carrying CSI reporting information, the priority of the first transmission carrying BFRQ, beam switching indication information, CSI reporting information or Inter UE Coordination (IUC) information is higher than the priority of the first transmission carrying feedback information, etc., and no limitation is made here.

[0117] The first condition may be configured according to communication requirements. For example, in this embodiment, the first condition may include at least one of the following (91)-(93).

[0118] (91) The first transmission conflicts with other transmissions.

[0119] (92) The first transmission exceeds the capacity of the first terminal.

[0120] (93) The transmit power of the first transmission exceeds the maximum transmit power of the first terminal.

[0121] In one implementation, in addition to having the function of sending the first transmission, the first terminal may also serve as a receiving end to receive the related transmission. For example, in this embodiment, the first terminal may also receive the second transmission sent by the third terminal based on the second resource. The second resource is determined by at least one of the following (101)-(104).

[0122] (101)Protocol predefined.

[0123] (102)Network configuration.

[0124] (103)Terminal configuration.

[0125] (104) determining, based on a second reference signal sent, the second reference signal being used for beam management. The second reference signal may be sent by the first terminal to a third terminal based on the SL for measurement or decoding, so that the third terminal sends a second transmission to the first terminal based on the measurement or decoding result. It can be understood that the description of the second transmission may refer to the description of the first transmission, and achieve the same or corresponding technical effect. To avoid repetition, it is not repeated here.

[0126] Optionally, the aforementioned process of the first terminal receiving the second transmission sent by the third terminal based on the second resource may include but is not limited to at least one of the following (1101)-1105.

[0127] (1101) Based on the second resource, the second transmission is received using beam scanning.

[0128] (1102) Receive the second transmission based on the second resource and using a second default beam.

[0129] The second default beam is similar to the aforementioned first default beam, and may also be determined by protocol pre-definition, network configuration or indication, terminal configuration or indication, negotiation between the first terminal and the third terminal, etc. For example, the second default beam may also be a wide beam (used for initial access).

[0130] (1103) Receive the second transmission based on the second resource and using a third beam or a beam pair, wherein the third beam or the beam pair corresponds to the beam used to send the second reference signal.

[0131] (1104) Receive the second transmission based on the second resource and using a fourth beam or a beam pair, wherein the fourth beam or a beam pair is a beam or a beam pair maintained between the first terminal and the third terminal (assuming there is no beam correspondence).

[0132] (1105) Based on the second resource, monitoring the second transmission based on a second transmission pattern.

[0133] In this embodiment, a resource mapping solution is provided, which enables the terminals on the SL to send and receive related transmissions, thereby achieving efficient and reliable beam management and improving the communication quality on the SL.

[0134] In addition, this embodiment can also effectively solve the half-duplex problem of SL transmission (such as PSFCH) and improve communication efficiency through the definition of the association period.
