[0027] Figure 1 A flow chart of a signal transmission method provided in an embodiment of the present application is executed by a base station (BS), such as Figure 1 As shown, the signal transmission method includes the following steps:

[0028] S101: Send configuration information, where the configuration information includes candidate resources.

[0029] In some embodiments of the present application, a base station may send configuration information to a user terminal, the configuration information including candidate resources. It should be noted that candidate resources are uplink resources used by the user terminal to send signaling and / or information to the base station. It is understood that there may be one or more candidate resources.

[0030] Optionally, the configuration information also includes at least one of the following: candidate beams, a correspondence table between candidate resources and candidate beams, and an identifier of a correspondence method between candidate resources and candidate beams.

[0031] In this embodiment, the base station may pre-configure candidate beams, a table of correspondences between candidate resources and candidate beams, and identifiers of methods for corresponding candidate resources and candidate beams, and transmit at least one of the three types of information and the candidate resources as configuration information to the user terminal. As another possible implementation, the user terminal may pre-configure at least one of the candidate beams, the corresponding method, and a calculation formula for configuring the corresponding relationship.

[0032] It is understood that there are one or more candidate resources and one or more candidate beams, and there is a correspondence between candidate resources and candidate beams, with each candidate resource corresponding to one candidate beam. For multiple candidate resources in each resource allocation period, one candidate beam can correspond to one or more candidate resources. For example, if there are four candidate resources in a 10ms resource allocation period, if there are four candidate beams, each candidate beam can correspond to one candidate resource. If there are two candidate beams, each candidate beam can correspond to two candidate resources.

[0033] Optionally, configuring a correspondence table between candidate resources and candidate beams may include at least one of the following:

[0034] Method 1: According to the candidate resources, candidate beams and corresponding methods, a preset corresponding method is used to configure a corresponding relationship table between the candidate resources and the candidate beams.

[0035] In this embodiment, a corresponding method is preset in the user terminal, and the preset corresponding method can be used to configure the corresponding relationship table between the candidate resources and the candidate beams.

[0036] Alternatively, if multiple corresponding methods are pre-set in the user terminal, the corresponding method corresponding to the identifier can be obtained from the preset multiple calculation formulas according to the identifier of the corresponding method sent by the base station, and the corresponding method corresponding to the identifier can be used to configure the correspondence table between the candidate resources and the candidate beams.

[0037] Method 2: Based on the candidate resources, candidate beams, and the corresponding method, a calculation formula corresponding to a preset corresponding method is used to configure a corresponding relationship table between the candidate resources and the candidate beams.

[0038] In this embodiment, a calculation formula corresponding to a corresponding method is pre-set in the user terminal, and the calculation and formula corresponding to the preset corresponding method can be used to configure the correspondence table between candidate resources and candidate beams.

[0039] Alternatively, if calculation formulas corresponding to multiple corresponding methods are pre-set in the user terminal, the calculation formula corresponding to the corresponding method corresponding to the identifier can be obtained from the preset multiple calculation formulas according to the identifier of the corresponding method sent by the base station, and the calculation formula corresponding to the corresponding method corresponding to the identifier can be used to configure the correspondence table between the candidate resources and the candidate beams.

[0040] The above preset corresponding methods and their corresponding calculation formulas include but are not limited to the following three or two forms:

[0041] For example, the corresponding method is to stagger candidate resources among candidate beams. The corresponding calculation formula is derived as follows: Assume that the total number of candidate resources in a resource allocation cycle is N, and the candidate resources are numbered from 0 to N-1. The total number of beams is M, and the beams are numbered from 0 to M-1. The number of resources allocated to each beam is N / M. The resource number allocated to the i-th beam is i+M*j, where j ranges from [0 to (N / M)-1].

[0042] For example, the corresponding method is to evenly distribute candidate resources among candidate beams. The corresponding calculation formula is derived as follows: Assume that the total number of candidate resources in a resource allocation cycle is N, and the candidate resources are numbered from 1 to N. The total number of beams is M, and the beams are numbered from 1 to M. The number of resources allocated to each beam is N / M. The resource number allocated to the i-th beam is [1 + (i-1) * (N / M), 1 + (i-1) * (N / M) + ((N / M) - 1)].

[0043] For example, a corresponding method is to evenly distribute candidate resources among candidate beams. Another corresponding calculation formula is derived as follows: Assume that the total number of candidate resources in a resource allocation cycle is N, and the candidate resources are numbered from 0 to N-1. The total number of beams is M, and the beams are numbered from 0 to M-1. Therefore, the number of resources allocated to each beam is N / M. The resource number allocated to the i-th beam is [i*(N / M), i*(N / M)+((N / M)-1)].

[0044] Optionally, the candidate beams may be configured via a broadcast message, and the candidate resources and the above-mentioned correspondence may be configured via dedicated signaling of the user terminal, wherein the dedicated signaling may be Radio Resource Control (RRC) signaling.

[0045] Optionally, the configuration information further includes at least one of the following: the type of the candidate resource, the status of the user terminal corresponding to the candidate resource, and resource configuration information of the candidate resource.

[0046] The candidate resource type includes at least one of the following types: a data channel, a control channel, and a sounding signal. For example, the data channel may include a physical uplink shared channel (PUSCH), the control channel may include a physical uplink control channel (PUCCH), and the sounding signal may include a sounding reference signal (SRS). It should be noted that when the candidate resource is an uplink control channel, the uplink transmission resource of the user terminal is an uplink grant (Configured Grant, CG) configured by the network.

[0047] The status of the user terminal corresponding to the candidate resource may include an idle (IDLE) state and an inactive (INACTIVE) state.

[0048] The resource configuration information includes at least one of the following information: a resource allocation period, a frequency domain resource location, a time domain starting resource location, the number of resources in the resource allocation period, a time domain interval between adjacent resources, and a frequency interval between adjacent resources. It should be noted that the frequency domain resource location includes but is not limited to a cell identifier and a bandwidth part (BWP) identifier.

[0049] Optionally, the configuration information may further include an identifier of a candidate beam, wherein the identifier of the candidate beam includes at least one of a synchronization signal block (SSB) identifier and a channel state information reference signal (CSI-RS) identifier.

[0050] S102: Receive a signal from a target resource among candidate resources.

[0051] In some embodiments of the present application, the user terminal may determine a target resource from candidate resources in the configuration information, and then send a signal on the target resource. Further, the base station may receive the signal sent by the user terminal on the target resource.

[0052] Optionally, when the configuration information also includes a correspondence table between candidate resources and candidate beams, the target resource is the candidate resource corresponding to the target beam in the candidate beams. For details on how the user terminal determines the target resource from the candidate resources in the configuration information, please refer to the relevant content of the user terminal side embodiment, which is not limited here.

[0053] S103: Send a feedback signal on the target beam corresponding to the target resource.

[0054] In the embodiment of the present application, the target resource is one of the candidate resources, and the target beam is one of the candidate beams.

[0055] In an embodiment of the present application, the base station may pre-configure a method for corresponding between candidate resources and candidate beams. The method may be a table of correspondence between candidate resources and candidate beams, or a preset calculation formula, through which the correspondence between candidate resources and candidate beams can be obtained. For example: the base station side has a built-in table of correspondence between candidate resources and candidate beams, and the target beam is obtained by entering the target resource into the table of correspondence, and a feedback signal is sent on the target beam; for another example: the base station side may have a built-in method for corresponding between candidate resources and candidate beams, and the method includes a preset calculation formula. The method or calculation formula may be used to obtain a table of correspondence between candidate resources and candidate beams, and the target beam is obtained by entering the target resource into the table of correspondence.

[0056] In some embodiments of the present application, the base station may send a feedback signal to the user terminal on a target beam corresponding to the target resource.

[0057] In related technologies, when a base station configures uplink resources for a user terminal, since the base station's downlink transmission beam will scan and send to different spatial locations at different times, when the base station receives the uplink resources sent by the user terminal, it is unclear on which beam the user terminal will receive the feedback signal, and therefore cannot accurately send the downlink feedback signal to the user terminal, which in turn causes the user terminal to be unable to receive the downlink feedback signal.

[0058] In this embodiment, configuration information is sent, including candidate resources, a signal from a target resource among the candidate resources is received, and a feedback signal is sent on a target beam corresponding to the target resource. Thus, the base station can send configuration information including candidate resources, receive signals from a target resource among the candidate resources, and send a feedback signal on a target beam corresponding to the target resource, thereby improving the reliability of feedback signal transmission by the base station.

[0059] Figure 2 This is a flow chart of another signal transmission method provided in an embodiment of the present application, which is executed by a base station. Figure 2 As shown, the signal transmission method includes the following steps:

[0060] S201: Send configuration information, where the configuration information includes candidate resources and at least one item in a correspondence table between candidate beams, candidate resource numbers, and candidate beam numbers.

[0061] In some embodiments of the present application, the correspondence table between candidate resources and candidate beams includes: a correspondence table between the numbers of the candidate resources and the numbers of the candidate beams.

[0062] It is understandable that before sending the configuration information, the base station may configure a correspondence table between the numbers of the candidate resources and the numbers of the candidate beams. The following two possible implementations may be included:

[0063] Method 1: Determine the number of groups according to the number of candidate beams, divide consecutively numbered candidate resources into the same group, correspond the numbers of the candidate resources in the same group with the number of the same candidate beam, and obtain a correspondence table between the numbers of the candidate resources and the numbers of the candidate beams.

[0064] For example, if the number of candidate resources is 8, the number of groups can be determined to be 2. The candidate resources numbered 1 to 4 are divided into group 1, and the candidate resources numbered 5 to 8 are divided into group 2. The candidate resources numbered 1 to 4 in group 1 correspond to candidate beam 1, and the candidate resources numbered 5 to 8 in group 2 correspond to candidate beam 2.

[0065] Method 2: Determine the number of groups based on the number of candidate beams, interleave and group the sequentially numbered candidate resources according to the group number, match the numbers of the candidate resources in the same group with the number of the same candidate beam, and obtain a correspondence table between the numbers of the candidate resources and the numbers of the candidate beams.

[0066] For example, if the number of candidate resources is 9, the number of groups can be determined to be 2. The candidate resources numbered 1, 3, 5, 7, and 9 are divided into group 1, and the candidate resources numbered 2, 4, 6, and 8 are divided into group 2. The candidate resources numbered 1, 3, 5, 7, and 9 in group 1 correspond to candidate beam 1, and the candidate resources numbered 2, 4, 6, and 8 in group 2 correspond to candidate beam 2.

[0067] In some embodiments of the present application, in order to distinguish multiple candidate resources within the same resource allocation period, at least one of the time domain resources, frequency domain resources, and demodulation signals of different candidate resources in the resource allocation period is different. The time domain resources may include time slots (SLOTs), the frequency domain resources may include physical resource blocks (PRBs), and the demodulation signals may include demodulation reference signals (DMRSs).

[0068] At this time, configuring the numbering of the candidate resources may include performing at least one of time domain numbering, frequency domain numbering, and demodulation signal numbering on the candidate resources.

[0069] The numbering order of at least one of the time domain number, the frequency domain number and the demodulated signal number is determined by the network configuration, or by the numbering rule agreed upon by the network configuration or the protocol.

[0070] For example, the time domain numbers may be numbered in chronological order or in reverse chronological order. For example, if the time domain numbers are numbered in chronological order, the number of the candidate resource with time slot 1 is smaller than the number of the candidate resource with time slot 2. Conversely, if the time domain numbers are numbered in reverse chronological order, the number of the candidate resource with time slot 1 is larger than the number of the candidate resource with time slot 2.

[0071] For example, the frequency domain numbers may be numbered from small to large or from large to small according to the frequency values. For example, if the frequency domain numbers are numbered from small to large according to the frequency values, the number of the candidate resource whose physical resource block PRB is 1 is smaller than the number of the candidate resource whose physical resource block PRB is 2. Conversely, if the frequency domain numbers are numbered from large to small according to the frequency values, the number of the candidate resource whose physical resource block PRB is 1 is larger than the number of the candidate resource whose physical resource block PRB is 2.

[0072] Configuring the numbering of candidate resources, if the candidate resources are numbered in the time domain and the frequency domain, can include the following two possible implementations:

[0073] Method 1: The time domain number is placed before the frequency domain number.

[0074] Optionally, the next resource of the last frequency domain resource in the current time domain is the unnumbered resource that is closest in time position and frequency to the last frequency domain resource. Figure 3 As shown, the frequency domain resources for time slot 1 are resources 1 to 3, then the last frequency domain resource for time slot 1 is resource 3, and the next resource is the unnumbered resource that is closest in time position and frequency to resource 3, which is taken as resource 4, and then the frequency domain resources for time slot 2 are resources 4 to 6.

[0075] Alternatively, the frequency domain resources in the same time domain are numbered in ascending order or descending order according to the frequency value. Figure 4 As shown, the frequency domain resources with time slot 1 are numbered from small to large according to the frequency value, and are numbered from 1 to 3 in sequence. The frequency domain resources with time slot 2 are numbered from small to large according to the frequency value, and are numbered from 4 to 6 in sequence.

[0076] Method 2: The frequency domain number is placed before the time domain number.

[0077] Optionally, the next resource of the last time domain resource in the current frequency domain is the resource that is closest in frequency position and time to the last time domain resource and has not yet been numbered. Figure 5As shown, the time domain resources with frequency f1 are 1 to 3, then the last time domain resource with frequency f1 is resource 3, and the next resource is the unnumbered resource that is closest to the frequency position and time of resource 3, which is regarded as resource 4, and the time domain resources with frequency f2 are resources 4 to 6.

[0078] Alternatively, the time domain resources in the same frequency domain are numbered in chronological order or in reverse chronological order. Figure 6 As shown, the time domain resources with a frequency of f1 are numbered in chronological order, from 1 to 3, and the time domain resources with a frequency of f2 are numbered in chronological order, from 4 to 6.

[0079] S202: Receive a signal from a target resource among candidate resources.

[0080] S203: Send a feedback signal on the target beam corresponding to the target resource.

[0081] In the embodiment of the present application, step S202 and step S203 can be implemented respectively using any of the methods in the embodiments of the present application. The embodiment of the present application does not limit this and will not be repeated.

[0082] In this embodiment, configuration information is sent, including candidate resources and at least one item from a table of correspondences between candidate beams, candidate resource numbers, and candidate beam numbers. A signal from a target resource is received, and a feedback signal is sent on the target beam corresponding to the target resource. Thus, the base station can determine the target beam corresponding to the target resource based on the table of correspondences between candidate resource numbers and candidate beam numbers, and send the feedback signal on the target beam corresponding to the target resource, thereby improving the reliability of downlink feedback signal transmission.

[0083] It is understandable that when the type of the candidate resource is a data channel, the Hybrid Automatic Repeat Request (HABQ) process numbers of the candidate resources in the resource allocation cycle are the same, or the HABQ process numbers of all configured candidate resources are the same.

[0084] Among them, when the hybrid automatic repeat request process numbers of the candidate resources in the resource allocation cycle are the same, the hybrid automatic repeat request process numbers of the candidate resources in the resource allocation cycle are determined according to the hybrid automatic repeat request process numbers of any one of the candidate resources with the earliest time domain, the latest time domain, the largest frequency, the smallest frequency, the smallest number and the largest number in the resource allocation cycle.

[0085] Figure 7 This is a flow chart of another signal transmission method provided in an embodiment of the present application, which is executed by a user terminal. Figure 7 As shown, the signal transmission method includes the following steps:

[0086] S301 : Select a target beam from candidate beams according to candidate resource configuration, candidate beam configuration, and a correspondence configuration between candidate resources and candidate beams.

[0087] In an embodiment of the present application, a user terminal may receive configuration information sent by a base station, where the configuration information includes candidate resources. The configuration information may also include at least one of candidate beams, a correspondence table between candidate resources and candidate beams, and an identifier of a correspondence method between candidate resources and candidate beams.

[0088] In some embodiments of the present application, the user terminal may configure at least one of the candidate beams, the correspondence method between candidate resources and candidate beams, and the calculation formula for configuring the correspondence relationship by itself, or the user terminal may receive configuration information sent by the base station, and the configuration information includes at least one of the candidate beams, the correspondence table between candidate resources and candidate beams, and the identifier of the correspondence method between candidate resources and candidate beams.

[0089] It can be understood that there are one or more candidate resources and candidate beams, and there is a corresponding relationship between the candidate resources and the candidate beams, and each candidate resource corresponds to one candidate beam.

[0090] Optionally, configuring a correspondence between candidate resources and candidate beams may include at least one of the following:

[0091] Method 1: According to the candidate resources, candidate beams and corresponding methods, a preset corresponding method is used to configure the corresponding relationship between the candidate resources and the candidate beams.

[0092] In this embodiment, a corresponding method is preset in the user terminal, and the preset corresponding method can be used to configure the corresponding relationship table between the candidate resources and the candidate beams.

[0093] Alternatively, if multiple corresponding methods are pre-set in the user terminal, the corresponding method corresponding to the identifier can be obtained from the preset multiple corresponding methods according to the identifier of the corresponding method sent by the base station, and the corresponding relationship between the candidate resources and the candidate beams can be configured using the corresponding method corresponding to the identifier.

[0094] Method 2: Based on the candidate resources, candidate beams, and the corresponding method, a calculation formula corresponding to a preset corresponding method is used to configure the corresponding relationship between the candidate resources and the candidate beams.

[0095] In this embodiment, a calculation formula corresponding to a corresponding method is pre-set in the user terminal, and the calculation and formula corresponding to the preset corresponding method can be used to configure the correspondence table between candidate resources and candidate beams.

[0096] Alternatively, if calculation formulas corresponding to multiple corresponding methods are pre-set in the user terminal, the calculation formula corresponding to the corresponding method corresponding to the identifier can be obtained from the preset multiple calculation formulas according to the identifier of the corresponding method sent by the base station, and the calculation formula corresponding to the corresponding method corresponding to the identifier can be used to configure the correspondence between the candidate resources and the candidate beams.

[0097] Optionally, when the configuration information sent by the network side only includes candidate resources, the user terminal detects the number of reference signals corresponding to the downlink beam, and numbers the downlink beam according to the number of reference signals and the rules agreed upon in the protocol. For example, if the user terminal detects that one SSB burst contains four SSB signals (for example, the four SSB signals are numbered SSB1 / 2 / 3 / 4 in time sequence), the user terminal determines that the number of downlink beams is four, and the four SSB signals correspond to four different beams, then beam 1 corresponds to SSB1, beam 2 corresponds to SSB2, and so on. The four beams corresponding to SSB1, SSB2, SSB3, and SSB4 are candidate beams. The user terminal obtains a correspondence table between candidate resources and candidate beams based on the candidate resources configured by the network, the candidate beams it detects, and the preset correspondence method or calculation formula between candidate resources and candidate beams.

[0098] The above preset corresponding methods and their corresponding calculation formulas include but are not limited to the following three forms:

[0099] For example, the corresponding method is to stagger candidate resources among candidate beams. The corresponding calculation formula is derived as follows: Assume that the total number of candidate resources in a resource allocation cycle is N, and the candidate resources are numbered from 0 to N-1. The total number of beams is M, and the beams are numbered from 0 to M-1. The number of resources allocated to each beam is N / M. The resource number allocated to the i-th beam is i+M*j, where j ranges from [0 to (N / M)-1].

[0100] For example, the corresponding method is to evenly distribute candidate resources among candidate beams. The corresponding calculation formula is derived as follows: Assume that the total number of candidate resources in a resource allocation cycle is N, and the candidate resources are numbered from 1 to N. The total number of candidate beams is M, and the candidate beams are numbered from 1 to M. The number of candidate resources allocated to each candidate beam is N / M. The candidate resource numbers allocated to the i-th candidate beam are [1 + (i-1) * (N / M), 1 + (i-1) * (N / M) + ((N / M) - 1)].

[0101] For example, a corresponding method is to evenly distribute candidate resources among candidate beams. Another corresponding calculation formula is derived as follows: Assume that the total number of candidate resources in a resource allocation cycle is N, and the candidate resources are numbered from 0 to N-1. The total number of candidate beams is M, and the candidate beams are numbered from 0 to M-1. Therefore, the number of candidate resources allocated to each candidate beam is N / M. The resource number allocated to the i-th candidate beam is [i*(N / M), i*(N / M)+((N / M)-1)].

[0102] Specifically, configuring the correspondence between candidate resources and candidate beams may include the following four possible implementations:

[0103] Method 1: If the user terminal only receives the candidate resource configuration, the correspondence between the candidate resources and the candidate beam can be configured according to the received candidate resource configuration, the preset candidate beam configuration and the preset corresponding method; or, the correspondence between the candidate resources and the candidate beam can be configured according to the received candidate resource configuration, the preset candidate beam configuration and the preset calculation formula.

[0104] Method 2: If the user terminal only receives candidate resource configuration and candidate beam configuration, the correspondence between the candidate resources and the candidate beams can be configured according to the received candidate resource configuration, the received candidate beam configuration and the preset correspondence method; or, the correspondence between the candidate resources and the candidate beams can be configured according to the received candidate resource configuration, the received candidate beam configuration and the preset calculation formula.

[0105] Method 3: If the user terminal only receives the candidate resource configuration and the identifier of the correspondence method between the candidate resources and the candidate beams, it can obtain the preset correspondence method or the calculation formula corresponding to the corresponding method according to the identifier of the corresponding method, and then configure the correspondence between the candidate resources and the candidate beams according to the received candidate resource configuration, the preset candidate beam configuration and the preset correspondence method; or, configure the correspondence between the candidate resources and the candidate beams according to the received candidate resource configuration, the preset candidate beam configuration and the calculation formula corresponding to the correspondence method.

[0106] Method 4: If the user terminal only receives the candidate resource configuration, the candidate beam configuration, and the identifier of the corresponding method between the candidate resources and the candidate beam, it can obtain the preset corresponding method or the calculation formula corresponding to the corresponding method according to the identifier of the corresponding method, and then configure the corresponding relationship between the candidate resources and the candidate beam according to the received candidate resource configuration, the received candidate beam configuration and the preset corresponding method; or, configure the corresponding relationship between the candidate resources and the candidate beam according to the received candidate resource configuration, the received candidate beam configuration and the calculation formula corresponding to the corresponding method.

[0107] Method 5: If the user terminal only receives the candidate resource configuration and the correspondence table between the candidate resources and the candidate beams, the correspondence between the candidate resources and the candidate beams can be configured according to the received candidate resource configuration, the preset candidate beam configuration, and the correspondence table between the received candidate resources and the candidate beams.

[0108] For example, the correspondence between candidate resources and candidate beams can be queried in the received correspondence table between candidate resources and candidate beams, and the correspondence between candidate resources and candidate beams can be configured based on the queried correspondence between candidate resources and candidate beams.

[0109] In an embodiment of the present application, the user terminal may select a target beam from candidate beams.

[0110] In some embodiments of the present application, the correspondence configuration between the candidate resources and the candidate beams includes: the correspondence configuration between the numbers of the candidate resources and the numbers of the candidate beams.

[0111] It is understandable that configuring the correspondence between the numbers of the candidate resources and the numbers of the candidate beams may include the following two possible implementations:

[0112] Method 1: Determine the number of groups according to the number of candidate beams, divide consecutively numbered candidate resources into the same group, and correspond the numbers of the candidate resources in the same group to the number of the same candidate beam.

[0113] For example, if the number of candidate resources is 8, the number of groups can be determined to be 2. The candidate resources numbered 1 to 4 are divided into group 1, and the candidate resources numbered 5 to 8 are divided into group 2. The candidate resources numbered 1 to 4 in group 1 correspond to candidate beam 1, and the candidate resources numbered 5 to 8 in group 2 correspond to candidate beam 2.

[0114] Method 2: Determine the number of groups according to the number of candidate beams, interleave and group the sequentially numbered candidate resources according to the group numbers, and correspond the numbers of the candidate resources in the same group to the number of the same candidate beam.

[0115] For example, if the number of candidate resources is 9, the number of groups can be determined to be 2. The candidate resources numbered 1, 3, 5, 7, and 9 are divided into group 1, and the candidate resources numbered 2, 4, 6, and 8 are divided into group 2. The candidate resources numbered 1, 3, 5, 7, and 9 in group 1 correspond to candidate beam 1, and the candidate resources numbered 2, 4, 6, and 8 in group 2 correspond to candidate beam 2.

[0116] In some embodiments of the present application, in order to distinguish multiple candidate resources within the same resource allocation period, at least one of the time domain resources, frequency domain resources, and demodulation signals of different candidate resources in the resource allocation period is different. The time domain resources may include time slots (SLOTs), the frequency domain resources may include physical resource blocks (PRBs), and the demodulation signals may include demodulation reference signals (DMRSs).

[0117] At this time, configuring the numbering of the candidate resources may include performing at least one of time domain numbering, frequency domain numbering, and demodulation signal numbering on the candidate resources.

[0118] The numbering order of at least one of the time domain number, the frequency domain number and the demodulated signal number is determined by the network configuration, or by the numbering rule agreed upon by the network configuration or the protocol.

[0119] For example, the time domain numbers may be numbered in chronological order or in reverse chronological order. For example, if the time domain numbers are numbered in chronological order, the number of the candidate resource with time slot 1 is smaller than the number of the candidate resource with time slot 2. Conversely, if the time domain numbers are numbered in reverse chronological order, the number of the candidate resource with time slot 1 is larger than the number of the candidate resource with time slot 2.

[0120] For example, the frequency domain numbers may be numbered from small to large or from large to small according to the frequency values. For example, if the frequency domain numbers are numbered from small to large according to the frequency values, the number of the candidate resource whose physical resource block PRB is 1 is smaller than the number of the candidate resource whose physical resource block PRB is 2. Conversely, if the frequency domain numbers are numbered from large to small according to the frequency values, the number of the candidate resource whose physical resource block PRB is 1 is larger than the number of the candidate resource whose physical resource block PRB is 2.

[0121] Configuring the numbering of candidate resources, if the candidate resources are numbered in the time domain and the frequency domain, can include the following two possible implementations:

[0122] Method 1: The time domain number is placed before the frequency domain number.

[0123] Optionally, the next resource of the last frequency domain resource in the current time domain is the unnumbered resource that is closest in time position and frequency to the last frequency domain resource. Figure 3 As shown, the frequency domain resources for time slot 1 are resources 1 to 3, then the last frequency domain resource for time slot 1 is resource 3, and the next resource is the unnumbered resource that is closest in time position and frequency to resource 3, which is taken as resource 4, and then the frequency domain resources for time slot 2 are resources 4 to 6.

[0124] Alternatively, the frequency domain resources in the same time domain are numbered in ascending order or descending order according to the frequency value. Figure 4 As shown, the frequency domain resources with time slot 1 are numbered from small to large according to the frequency value, and are numbered from 1 to 3 in sequence. The frequency domain resources with time slot 2 are numbered from small to large according to the frequency value, and are numbered from 4 to 6 in sequence.

[0125] Method 2: The frequency domain number is placed before the time domain number.

[0126] Optionally, the next resource of the last time domain resource in the current frequency domain is the resource that is closest in frequency position and time to the last time domain resource and has not yet been numbered. Figure 5 As shown, the time domain resources with frequency f1 are 1 to 3, then the last time domain resource with frequency f1 is resource 3, and the next resource is the unnumbered resource that is closest to the frequency position and time of resource 3, which is regarded as resource 4, and the time domain resources with frequency f2 are resources 4 to 6.

[0127] Alternatively, the time domain resources in the same frequency domain are numbered in chronological order or in reverse chronological order. Figure 6 As shown, the time domain resources with a frequency of f1 are numbered in chronological order, from 1 to 3, and the time domain resources with a frequency of f2 are numbered in chronological order, from 4 to 6.

[0128] S302: Determine, according to the corresponding relationship, the candidate resource corresponding to the target beam as the target resource.

[0129] In an embodiment of the present application, the user terminal may determine that the candidate resource corresponding to the target beam is the target resource based on the correspondence between the candidate resources and the candidate beams.

[0130] S303: Send a signal on the target resource.

[0131] In some embodiments of the present application, the user terminal may send a signal to the base station on the target resource.

[0132] Optionally, sending the signal on the target resource may include obtaining the location of the target resource and sending the signal on the target resource according to the location of the target resource.

[0133] In some embodiments of the present application, the candidate resource configuration includes resource configuration information of the candidate resource. In this case, the location of the candidate resource can be determined according to the resource configuration information of the candidate resource.

[0134] The resource configuration information of the candidate resources may include at least one of a resource allocation period, a frequency domain resource position, a time domain starting resource position, the number of resources in the resource allocation period, a time domain interval between adjacent resources, and a frequency interval between adjacent resources. Accordingly, determining the position of the candidate resources based on the resource configuration information of the candidate resources may include determining the position of the first candidate resource in the resource allocation period based on the resource allocation period and the time domain starting resource position, and after determining the position of the first candidate resource in the resource allocation period, determining the positions of the second to last candidate resources in the resource allocation period based on at least one of the number of resources in the resource allocation period, the time domain interval between adjacent resources, and the frequency interval between adjacent resources.

[0135] Optionally, determining the position of the first candidate resource in the resource allocation cycle based on the resource allocation cycle and the time domain starting resource position may include determining the position of the first candidate resource based on a calculation formula between the position of the first candidate resource and the resource allocation cycle and the time domain starting resource position.

[0136] It is understood that after determining the position of the first candidate resource in the resource allocation period, the positions of the second to last candidate resources in the resource allocation period may be determined based on at least one of the number of resources in the resource allocation period, the time domain interval between adjacent resources, and the frequency interval between adjacent resources. For example, the position of the second candidate resource may be determined based on the position of the first candidate resource and the time domain interval between adjacent resources.

[0137] In this embodiment, based on the candidate resource configuration, the candidate beam configuration, and the correspondence configuration between candidate resources and candidate beams, a target beam is selected from the candidate beams. The candidate resource corresponding to the target beam is determined as the target resource based on the correspondence, and a signal is transmitted on the target resource. Thus, the user terminal can select a target beam from the candidate beams, then determine the candidate resource corresponding to the target beam as the target resource based on the correspondence between the candidate resources and candidate beams, and transmit a signal on the target resource.

[0138] Figure 8 This is a flow chart of another signal transmission method provided in an embodiment of the present application, which is executed by a user terminal. Figure 8 As shown, the signal transmission method includes the following steps:

[0139] S401 : Select a target beam from candidate beams according to candidate resource configuration, candidate beam configuration, and a correspondence configuration between candidate resources and candidate beams.

[0140] In some embodiments of the present application, selecting a target beam from candidate beams may include the following two possible implementations:

[0141] Method 1: Determine a candidate beam whose measurement value is equal to or greater than a preset measurement threshold among the candidate beams as a target beam.

[0142] The preset measurement threshold may be determined by network configuration or protocol agreement.

[0143] For example, if the reference signal receiving power (RSRP) in the candidate beam whose synchronization signal block SSB is 1 is equal to or greater than the preset measurement threshold, the user terminal can select the candidate beam whose synchronization signal block SSB is 1 as the target beam.

[0144] Method 2: Determine the candidate beam corresponding to the candidate resource with the closest transmission time of the corresponding user terminal among the candidate resources as the target beam.

[0145] For example, if the transmission time of resource 1 is the latest, the candidate beam corresponding to resource 1 can be determined as the target beam.

[0146] In some embodiments of the present application, the candidate resource configuration may include the status of the user terminal corresponding to the candidate resource, where the status of the user terminal may include an idle state or an inactive state. Selecting a target beam from the candidate beams may include the following two possible implementations:

[0147] Method 1: Determine as the target beam a candidate beam whose measurement value is equal to or greater than a preset measurement threshold and whose corresponding candidate resource corresponds to a user terminal whose state is consistent with the current state of the user terminal.

[0148] For example, if the reference signal receiving power (RSRP) in the candidate beam whose synchronization signal block SSB is 1 is equal to or greater than the preset measurement threshold, and the state of the user terminal corresponding to the candidate beam whose synchronization signal block SSB is 1 is consistent with the current state of the user terminal, the user terminal can select the candidate beam whose synchronization signal block SSB is 1 as the target beam.

[0149] Method 2: Determine as the target beam the candidate beam corresponding to the candidate resource whose corresponding user terminal has the latest transmission time and whose corresponding user terminal state is consistent with the current state of the user terminal.

[0150] For example, if the transmission time of resource 1 is the latest, and the state of the user terminal corresponding to the candidate beam of resource 1 is consistent with the current state of the user terminal, the candidate beam corresponding to resource 1 can be determined as the target beam.

[0151] S402: Determine, according to the corresponding relationship, the candidate resource corresponding to the target beam as the target resource.

[0152] In the embodiment of the present application, step S402 can be implemented in any of the ways in the embodiments of the present application. The embodiment of the present application does not limit this and will not be described in detail.

[0153] S403: Send a signal on the target resource.

[0154] It can be understood that the candidate resource configuration may also include at least one of the hybrid automatic repeat request (HABQ) process number of the candidate resource and the number of hybrid automatic repeat request processes. When the type of the candidate resource is a data channel, the hybrid automatic repeat request process number of the candidate resources in the resource allocation cycle is the same, or the hybrid automatic repeat request process number of all configured candidate resources is the same.

[0155] Among them, when the hybrid automatic repeat request process numbers of the candidate resources in the resource allocation cycle are the same, the hybrid automatic repeat request process numbers of the candidate resources in the resource allocation cycle are determined according to the hybrid automatic repeat request process numbers of any one of the candidate resources with the earliest time domain, the latest time domain, the largest frequency, the smallest frequency, the smallest number and the largest number in the resource allocation cycle.

[0156] Optionally, sending the signal on the target resource may include determining a target HARQ process based on a HARQ process number of the target resource, and using the target HARQ process to send the signal on the target resource. For example, if the HARQ process number of the target resource is 5, the target HARQ process may be determined to be 5, and the signal may be sent on the target resource using the target HARQ process.

[0157] Optionally, after sending a signal on the target resource, a feedback signal can be monitored via a channel, where the spatial relationship of the channel is determined based on the target beam corresponding to the target resource. The channel includes but is not limited to the Physical Downlink Control Channel (PDCCH) and the Physical Downlink Shared Channel (PDSCH).

[0158] For example, if the target beam is a candidate beam whose synchronization signal block SSB is 1, the channel spatial relationship can be determined based on the candidate beam whose synchronization signal block SSB is 1.

[0159] S404: Receive a feedback signal on a target beam corresponding to the target resource.

[0160] In some embodiments of the present application, the user terminal may receive a feedback signal sent by the base station on a target beam corresponding to a target resource.

[0161] In this embodiment, based on the candidate resource configuration, the candidate beam configuration, and the correspondence configuration between the candidate resources and the candidate beams, a target beam is selected from the candidate beams, the candidate resource corresponding to the target beam is determined as the target resource based on the correspondence, a signal is transmitted on the target resource, and a feedback signal is received on the target beam corresponding to the target resource. Thus, the user terminal can select a target beam from the candidate beams, then determine the candidate resource corresponding to the target beam as the target resource based on the correspondence between the candidate resources and the candidate beams, transmit a signal on the target resource, and receive a feedback signal on the target beam, thereby improving the reliability of the user terminal's reception of feedback signals.
