[0042] There is a conflict in time domain resources of multiple beams, and a first beam is determined based on the multiple beams, where the first beam includes a beam used by the repeater for communication.

[0043] In the above embodiment, the beam used by the repeater for communication is determined from the beams with conflicting time domain resources, ensuring that the determined beams can be used by the repeater, thereby improving the accuracy of the beam used by the repeater and further improving communication reliability.

[0044] In conjunction with some embodiments of the first aspect, in some embodiments, determining the first beam based on the multiple beams includes:

[0045] The number of the multiple beams is not greater than a first threshold, and the first beam is determined in a beam indication manner.

[0046] In the above embodiment, if the number of multiple beams is not greater than the first threshold, it means that the multiple beams have not reached the upper limit of the maximum beam supported by the repeater. Therefore, the first beam is directly determined according to the beam indication, and the repeater can use the determined first beam, which improves the accuracy of the beam used by the repeater and thereby improves the communication reliability.

[0047] In conjunction with some embodiments of the first aspect, in some embodiments, determining the first beam based on the multiple beams includes:

[0048] The number of the multiple beams is greater than a first threshold, and the first beam is determined according to a first rule.

[0049] In the above embodiment, if the number of multiple beams is greater than the first threshold, it means that the multiple beams exceed the upper limit of the maximum beam supported by the repeater. Therefore, the first beam is selected from the multiple beams according to the first rule, and the repeater only needs to use the determined first beam, thereby improving the accuracy of the beam used by the repeater and thereby improving the communication reliability.

[0050] In conjunction with some embodiments of the first aspect, in some embodiments, the number of the multiple beams is greater than a first threshold, and determining the first beam according to a first rule includes:

[0051] The first beam is determined based on the first threshold and a priority rule.

[0052] In the above embodiment, the repeater determines the first beam according to the first threshold and the priority rule, ensuring that the determined first beams are all priority beams, thereby improving the accuracy of the beams used by the repeater and further improving communication reliability.

[0201] In some embodiments, the maximum number of beams that the repeater transmits simultaneously indicated by the configuration information is no greater than the maximum number of beams that the repeater transmits simultaneously indicated by the capability information.

[0202] It should be noted that the embodiment of the present application is described by taking the example of a network device sending configuration information. In another embodiment, the OAM may send the configuration information. In other words, step S2102 may be replaced by: OAM sends the configuration information.

[0203] In step S2103 , the network device determines that time domain resources of multiple beams conflict, where the multiple beams include a first beam, and the first beam includes a beam used by the repeater for communication.

[0204] In some embodiments, each of the multiple beams corresponds to a time domain resource. If the time domain resources of the multiple beams overlap, it indicates that there is a conflict in the time domain resources of the multiple beams.

[0205] In some embodiments, the time domain resource corresponds to a time slot, a symbol or other resources, which is not limited in the embodiments of the present disclosure.

[0206] In some embodiments, the first beam comprises a beam used by the repeater for communication. In some embodiments, the first beam comprises a beam used by the repeater for communication in an access link.

[0207] Step S2104: The network device sends a beam indication.

[0208] In some embodiments, the beam indication is used to indicate a beam. In some embodiments, the beam indication includes at least one of a periodic beam indication, a semi-static beam indication, and an aperiodic beam indication.

[0209] In some embodiments, the beam indication may also be referred to as a periodic resource set, or other names, which is not limited in the embodiments of the present disclosure.

[0210] In some embodiments, if the beam indication is a periodic beam indication, the periodic beam indication includes at least one of a periodic resource set identifier, a periodic resource identifier, a priority identifier, and an SCS (Sub Carrier Space). Optionally, the periodic resource identifier includes at least one of a beam identifier and a time domain resource.

Optionally, the aperiodic resource identifier includes at least one of a beam identifier and a time domain resource. Optionally, the time domain resource includes at least one of a slot offset value, a symbol offset value, and a symbol duration.

[0213] In step S2105 , the repeater parses the beam indication and obtains multiple beams.

[0214] In some embodiments, the repeater obtains a beam indication and parses the obtained beam indication to obtain multiple beams.

[0215] In some embodiments, the repeater parses the beam indication, obtains multiple beams, and determines the time domain resource of each of the multiple beams.

[0216] Step S2106: There is a conflict in time domain resources of multiple beams. The repeater determines a first beam based on the multiple beams. The first beam includes a beam used by the repeater for communication.

[0217] In some embodiments, the first beam comprises a beam used by the repeater to communicate in an access link.

[0218] In some embodiments, the time domain resource is used to indicate the time domain resource occupied by the beam. Alternatively, it can be understood that the time domain resource indicates the time domain resource required by the repeater to send the beam.

[0219] In some embodiments, the first beam is all beams in the plurality of beams. In other embodiments, the first beam is part of the plurality of beams.

[0220] In some embodiments, the number of the multiple beams is not greater than a first threshold, and the first beam is determined in a beam indication manner.

[0221] Optionally, the first threshold is used to indicate the maximum number of beams that the repeater supports to transmit simultaneously. Alternatively, it can also be understood that the first threshold is used to indicate the maximum number of beams that the repeater can transmit at the same time.

[0222] Optionally, the first threshold is used to indicate the maximum number of beams that the repeater supports to be sent simultaneously in the access link. Alternatively, it can also be understood that the first threshold is used to indicate the maximum number of beams that the repeater can send simultaneously in the access link.

[0223] In an embodiment of the present disclosure, if the number of multiple beams is not greater than the first threshold, it means that the number of conflicting beams is not greater than the maximum number of beams supported by the repeater to be sent simultaneously. At this time, the repeater can directly use the beam indicated by the beam.

[0224] In some embodiments, the number of the plurality of beams is greater than a first threshold, and the first beam is determined according to a first rule.

[0225] In an embodiment of the present disclosure, if the number of multiple beams is greater than the first threshold, it means that the number of conflicting beams is greater than the maximum number of beams that the repeater supports to send simultaneously, and the repeater cannot use all beams. Therefore, it is necessary to determine the first beam from the multiple beams according to the first rule.

[0226] Optionally, the first rule is used to select a beam for priority use from a plurality of beams. Alternatively, it can be understood that the first rule is used to select a beam that meets a use condition from a plurality of beams.

[0227] In some embodiments, the name of the first rule is not limited, and can be, for example, a first rule, a first condition, etc.

[0228] In some embodiments, the first beam is determined based on a first threshold and a priority rule.

[0229] Optionally, the priority rule is used to indicate the priority of multiple beams. Alternatively, it can be understood that the priority rule is used to indicate a beam to be used preferentially among multiple beams.

[0230] In an embodiment of the present disclosure, the repeater selects, from multiple beams, a first beam whose number is no greater than a first threshold and that satisfies a priority rule. In some embodiments, the priority rule indicates how to determine the beam to be used. Alternatively, the priority rule may be understood as indicating the priority of the beams to be used. Alternatively, the priority rule may be understood as indicating how to select the beam to be used first.

[0231] In some embodiments, the priority rule includes at least one of the following:

[0232] (1) Multiple non-periodic beam indications conflict, and the beam indicated by the first DCI is determined to be the first beam, and the first DCI is the most recently received DCI.

[0233] In some embodiments, the aperiodic beam indication is indicated by a DCI. If beams indicated by multiple aperiodic beam indications conflict, the beam indicated by the most recently received DCI is determined as the first beam.

[0234] (2) The beam indication includes a periodic beam indication and a semi-static beam indication, and both the periodic beam indication and the semi-static beam indication include a priority identifier to determine the beam to be indicated by the semi-static beam.

[0235] In some embodiments, if both the periodic beam indication and the semi-static beam indication include priority identifiers, the beam indicated by the semi-static beam is determined to be used. Alternatively, it can be understood that the beam indicated by the semi-static beam is determined as the first beam.

[0236] (3) The beam indication includes a periodic beam indication and a semi-static beam indication, and neither the periodic beam indication nor the semi-static beam indication includes a priority identifier, and the beam indicated by the semi-static beam is determined.

[0237] In some embodiments, if neither the periodic beam indication nor the semi-static beam indication includes a priority identifier, the beam indicated by the semi-static beam is determined to be used. Alternatively, it can be understood that the beam indicated by the semi-static beam is determined as the first beam.

[0238] (4) The beam indication includes a periodic beam indication and a semi-static beam indication, and one of the periodic beam indication and the semi-static beam indication includes a priority flag, and the beam of the beam indication including the priority flag is determined to be used.

[0239] In some embodiments, if the periodic beam indication includes a priority identifier and the semi-static beam indication does not include a priority identifier, the beam indicated by the periodic beam is determined to be used, or it can also be understood that the beam indicated by the periodic beam is determined as the first beam.

[0240] In some embodiments, if the periodic beam indication does not include a priority identifier and the semi-static beam indication includes a priority identifier, then the beam indicated by the semi-static beam is determined to be used, or it can also be understood that the beam indicated by the semi-static beam is determined as the first beam.

[0241] (5) The beam indication includes a periodic beam indication and a non-periodic beam indication, and one of the periodic beam indication and the non-periodic beam indication includes a priority flag, and the beam including the beam indication including the priority flag is determined to be used.

[0242] In some embodiments, if the periodic beam indication includes a priority identifier and the non-periodic beam indication does not include a priority identifier, the beam indicated by the periodic beam is determined to be used, or it can also be understood that the beam indicated by the periodic beam is determined as the first beam.

[0243] In some embodiments, if the periodic beam indication does not include a priority identifier and the non-periodic beam indication includes a priority identifier, then the beam indicated by the non-periodic beam is determined to be used, or it can also be understood that the beam indicated by the non-periodic beam is determined as the first beam.

[0244] (6) The beam indication includes a periodic beam indication and a non-periodic beam indication, and neither the periodic beam indication nor the non-periodic beam indication includes a priority identifier, and the beam using the non-periodic beam indication is determined.

[0245] In some embodiments, if neither the periodic beam indication nor the aperiodic beam indication includes a priority identifier, the beam indicated by the aperiodic beam indication is determined to be used. Alternatively, it can be understood that the beam indicated by the aperiodic beam indication is determined as the first beam.

[0246] (7) The beam indication includes a semi-static beam indication and an aperiodic beam indication, and one of the semi-static beam indication and the aperiodic beam indication includes a priority flag, and the beam including the beam indication including the priority flag is determined to be used.

[0247] In some embodiments, if the semi-static beam indication includes a priority identifier and the non-periodic beam indication does not include a priority identifier, then the beam indicated by the semi-static beam is determined to be used, or it can also be understood that the beam indicated by the semi-static beam is determined as the first beam.

[0248] In some embodiments, if the semi-static beam indication does not include a priority identifier and the non-periodic beam indication includes a priority identifier, the beam indicated by the non-periodic beam is determined to be used, or it can also be understood that the beam indicated by the non-periodic beam is determined as the first beam.

[0249] (8) The beam indication includes a semi-static beam indication and an aperiodic beam indication, and neither the semi-static beam indication nor the aperiodic beam indication includes a priority identifier, and the beam using the aperiodic beam indication is determined.

[0250] In some embodiments, if neither the semi-static beam indication nor the aperiodic beam indication includes a priority identifier, the beam indicated by the aperiodic beam indication is determined to be used. Alternatively, it can be understood that the beam indicated by the aperiodic beam indication is determined as the first beam.

[0251] In some embodiments, if the number of beams determined by the above priority rule is not greater than the first threshold, it is necessary to continue to determine whether to determine other beams as the first beam.

[0252] In some embodiments, the above-mentioned priority rules can also be called agreed rules, priority rules, priority criteria, beam criteria, beam selection criteria, etc., which are not limited in the embodiments of the present disclosure.

[0253] In some embodiments, how to determine the first beam is described:

[0254] The first type: if the number of beams to be used is determined based on the first threshold and the priority rule to be no greater than the first threshold, the beam to be used based on the first threshold and the priority rule is determined as the first beam.

[0255] In some embodiments, the beam determined to be used based on the first threshold and the priority rule is directly determined as the first beam. It can also be understood that after the beam to be used is determined based on the first threshold and the priority rule, even if the number of determined beams is not greater than the first threshold, the determined beam is still determined as the first beam.

[0256] For example, if beam 1, beam 2, and beam 3 are determined based on the first threshold and the priority rule, and the first threshold is 4, beam 1, beam 2, and beam 3 are determined as the first beam.

[0257] The second type: the number of beams determined to be used based on the first threshold and the priority rule is not greater than the first threshold, and the beams determined to be used based on the first threshold and the priority rule, and the first number of beams determined from beams other than the beams determined to be used based on the first threshold and the priority rule, are determined as the first beams.

[0258] In some embodiments, the number of beams determined to be used based on the first threshold and the priority rule is not greater than the first threshold, and not only the beams determined to be used based on the first threshold and the priority rule are determined as the first beams, but also a first number of beams determined from beams other than the beams determined to be used based on the first threshold and the priority rule are determined as the first beams.

[0259] In some embodiments, the first number is the difference between the first threshold and the number of beams to be used based on the first threshold and the priority rule. For example, if the number of beams to be used based on the first threshold and the priority rule is N, and the first threshold is M, then the first number is MN. If M is 4 and N is 2, then the first number is 2.

[0260] In some embodiments, a description is provided of how to determine the first number of beams from beams other than beams determined to be used based on a first threshold and a priority rule.

[0261] The first type: the first number of beams are determined in descending order of beam identifiers.

[0262] Second type: the first number of beams is determined according to the order of the first information from front to back.

[0263] In some embodiments, the first information is carried in any one of RRC, DCI or MAC CE.

[0264] Optionally, for periodic beam indication, a first number of beams are selected according to the order in RRC.

[0265] Optionally, for non-periodic beam indication, a first number of beams are selected according to the order in the DCI.

[0266] Optionally, for semi-static beam indication, the relay updates the beam information in the list via MAC CE. Therefore, there are two cases:

[0267] Case 1: The network device does not update the beam information in the RRC configuration through MAC CE. At this time, the first number of beams is determined according to the order in the RRC.

[0268] Case 2: The network device updates the beam information in the RRC configuration through MAC CE. At this time, the first number of beams is determined according to the order in the MAC CE.

[0269] In some embodiments, the first beam is determined based on a first threshold and an agreed rule.

[0270] Optionally, the agreed rule is used to agree on the time domain resources of the beam indicated by the beam.

[0271] In some embodiments, the agreed rules include at least one of the following:

[0272] (1) In a list or multiple lists of periodic beam indications, the number of first beams on the same time domain resource is less than a first threshold, and the list includes at least one beam identifier.

[0273] In some embodiments, the periodic beam indication includes at least one list, each list includes at least one beam identifier, and the number of first beams indicated by the periodic beam indication is less than a first threshold. It can also be understood that the number of conflicting beams indicated by the periodic beam indication is less than the first threshold.

[0274] In some embodiments, the above (1) can also be understood as that the repeater does not expect that the number of first beams on the same time domain resource in the periodic beam indication of one list or multiple lists is less than the first threshold.

[0275] (2) In a list or a plurality of lists of semi-static beam indications, the number of first beams on the same time domain resource is less than a first threshold, and the list includes at least one beam identifier.

[0276] In some embodiments, the semi-static beam indication includes at least one list, each list includes at least one beam identifier, and the number of first beams indicated by the semi-static beam is less than a first threshold. It can also be understood that the number of conflicting beams indicated by the semi-static beam is less than the first threshold.

[0277] In some embodiments, the above (2) can also be understood as that the repeater does not expect that the number of first beams on the same time domain resource in the semi-static beam indications of one list or multiple lists is less than the first threshold.

[0278] (3) Within a beam indication of a DCI, the number of first beams on the same time domain resource is less than a first threshold.

[0279] In some embodiments, the beam indication of the DCI includes multiple beams, but the number of the first beams in the multiple beams, that is, the number of the first beams with time domain resource conflicts, is less than a first threshold.

[0280] In some embodiments, the above (3) can also be understood as that the repeater does not expect that the number of first beams on the same time domain resource within the beam indication of a DCI is less than the first threshold.

[0342] FIG6 is a flow chart of a beam determination method according to an embodiment of the present disclosure. As shown in FIG6 , the embodiment of the present disclosure relates to a beam determination method, which includes:

[0343] Step S6101: The base station and / or NCR-MT determines the maximum number of beams that the NCR-Fwd supports sending simultaneously on the access link.

[0344] In some embodiments, the number of beams is N.

[0345] Option 1: Determine through NCR capability reporting.

[0346] Option 2: Determine through OAM information.

[0347] In some embodiments, when the number of different beam indices (associated) corresponding to the same time (overlapping time resource) is <= N, the NCR applies the beam according to the beam indication; when the number of different beam indices (associated) corresponding to the same time (overlapping time resource) is > N, a part of the conflicting beam indications is selected for application according to certain rules.

[0348] In some embodiments, the NCR determines the beam to use when conflicting beam indications occur based on N and a priority criterion.

[0349] In some embodiments, the priority criterion is at least one of the following:

[0350] NCR does not want the periodic beam indications within a list or multiple lists to have the number of different beams on the same time resource to be greater than N. One of the lists is a beam ID list configured in the PeriodicFwdResourceSet.

[0351] NCR does not want the number of different beams on the same time resource to be greater than N in a list or multiple lists of semi-static beam indications. One of the lists is a list of beam IDs configured in a SemiPersistentFwdResourceSet.

[0352] NCR does not want the beam indication in a DCI to have a number of different beams > N on the same time resource.

[0353] For conflicts between multiple non-periodic beam indications, the beam indicated by the most recent DCI is applied first.

[0354] For periodic and semi-static, if both have priority flags or neither has priority flag, semi-static takes precedence.

[0355] For periodic and semi-static, if one has a priority flag and the other does not, the one with the priority flag takes precedence.

[0356] For periodic / semi-static and aperiodic:

[0357] If periodic / semi-static has no priority flag, aperiodic is applied first.

[0358] If the periodic / semi-static mode has a priority flag, the periodic / semi-static mode is applied first.

[0359] In some embodiments, the NCR determines the beam indication to be used on overlapping resources in the following two ways.

[0360] Optionally, only the priority beam indication is applied

[0361] Optionally, if the number of beams indicated by the priority beam on the overlapping time resource is less than N, then NM beams in the non-priority beam indication are applied, where M is the number of beams indicated by the priority on the overlapping time resource. The selection of NM can be determined by predefined rules, such as (1) beam ID size arrangement and (2) order of arrangement in the RRC configuration or DCI indication.

[0362] In some embodiments, the priority rules for NCR devices shown in the above embodiments are also applicable to RIS devices.

[0363] In the embodiments of the present disclosure, some or all of the steps and their optional implementations may be arbitrarily combined with some or all of the steps in other embodiments, or may be arbitrarily combined with the optional implementations of other embodiments.

[0364] The present disclosure also provides an apparatus for implementing any of the above methods. For example, an apparatus is provided that includes units or modules for implementing each step performed by a relay in any of the above methods. For another example, another apparatus is provided that includes units or modules for implementing each step performed by a network device (e.g., an access network device, a core network function node, a core network device, etc.) in any of the above methods.

[0365] It should be understood that the division of the various units or modules in the above device is merely a division of logical functions. In actual implementation, they may be fully or partially integrated into a physical entity, or they may be physically separated. In addition, the units or modules in the device may be implemented in the form of a processor calling software: for example, the device includes a processor, the processor is connected to a memory, and the memory stores instructions. The processor calls the instructions stored in the memory to implement any of the above methods or implement the functions of the various units or modules of the above device, wherein the processor is, for example, a general-purpose processor, such as a central processing unit (CPU) or a microprocessor, and the memory is a memory within the device or a memory outside the device. Alternatively, the units or modules in the device can be implemented in the form of hardware circuits, and the functions of some or all of the units or modules can be realized by designing the hardware circuits. The above-mentioned hardware circuits can be understood as one or more processors; for example, in one implementation, the above-mentioned hardware circuit is an application-specific integrated circuit (ASIC), and the functions of some or all of the above units or modules are realized by designing the logical relationship of the components in the circuit; for example, in another implementation, the above-mentioned hardware circuit can be realized by a programmable logic device (PLD). Taking a field programmable gate array (FPGA) as an example, it can include a large number of logic gate circuits, and the connection relationship between the logic gate circuits is configured by configuring the configuration file, thereby realizing the functions of some or all of the above units or modules. All units or modules of the above devices can be realized in the form of software called by the processor, or in the form of hardware circuits, or in part by the form of software called by the processor, and the remaining part by the form of hardware circuits.

In one implementation, the processor can be a circuit with instruction reading and execution capabilities, such as a central processing unit (CPU), a microprocessor, a graphics processing unit (GPU) (which can be understood as a microprocessor), or a digital signal processor (DSP). In another implementation, the processor can implement certain functions through the logical relationship of the hardware circuit. The logical relationship of the above-mentioned hardware circuit is fixed or reconfigurable. For example, the processor is a hardware circuit implemented by an application-specific integrated circuit (ASIC) or a programmable logic device (PLD), such as an FPGA. In a reconfigurable hardware circuit, the process of the processor loading a configuration document and implementing the hardware circuit configuration can be understood as the process of the processor loading instructions to implement the functions of some or all of the above units or modules. In addition, it can also be a hardware circuit designed for artificial intelligence, which can be understood as an ASIC, such as a neural network processing unit (NPU), a tensor processing unit (TPU), a deep learning processing unit (DPU), etc.
