[0024] The following description, in conjunction with the accompanying drawings, details a transmission method, apparatus, terminal, and storage medium provided in this application through some embodiments and application scenarios.

[0025] Please see Figure 2 , Figure 2 This is a flowchart of a transmission method provided in an embodiment of this application, such as... Figure 2 As shown, the steps include:

[0026] Step 201: The terminal's configuration resources include N frequency domain resources, and the terminal transmits data in the frequency domain resources among the N frequency domain resources when the preset conditions are met. The transmission is based on the transmission channels among the M transmission channels, and N is an integer greater than 2.

[0027] The terminal has M transmission channels, or the terminal can transmit on up to M transmission channels simultaneously, where M is a positive integer less than or equal to N.

[0028] In this embodiment of the application, frequency domain resources include the following:

[0029] Frequency band, carrier, bandwidth part (BWP), and resource pool.

[0030] The aforementioned N frequency domain resources can be three or more frequency bands, carriers, BWPs, or resource pools.

[0031] The configuration resources of the aforementioned terminal can be the resources configured for the terminal by the network-side equipment.

[0032] The aforementioned conditions for meeting the preset conditions can be conditions configured by the network-side devices or conditions agreed upon by the protocol. Specifically, at least one of the terminal's transmission, configuration, and capabilities can meet the aforementioned preset conditions.

[0033] The aforementioned M transmission channels can be uplink transmission channels (UL Tx) or SL transmission channels (SL Tx). In some implementations, M can be equal to 2, or M can be equal to N, such as N being 3, in which case M is also 3.

[0034] Transmission using the aforementioned N frequency domain resources can be performed on some or all of the aforementioned N frequency domain resources, and these transmissions can be performed using all or some of the aforementioned M transmission channels. For example, the terminal has T1, T2…TN numbers of Tx in N frequency bands, carriers, BWPs, or resource pools, and sum(T1,T2…TN)=M, and 0<=Tm<=M, 0<=m<=N.

[0035] In the embodiments of this application, the above steps can enable transmission in more than two frequency domain resources, thereby improving the transmission performance of the terminal.

[0036] As an optional implementation, the transmission of frequency domain resources among the N frequency domain resources includes:

[0037] The transmission channel is switched among the N frequency domain resources, and transmission is performed based on the switched frequency domain resources.

[0038] The aforementioned transmission channel switching may include at least one of the following:

[0039] Changes in the frequency domain resource index of the transmission;

[0040] Changes in the transmission channels, antenna ports, number of layers, or number of resource pools;

[0041] The number of frequency domain resources transmitted changes.

[0042] For example, the above-mentioned frequency domain resource transmission channel switching in N frequency domain resources can be achieved by changing the frequency domain resource index of some or all of the resources transmitted in N frequency domain resources, or changing the transmission channel, antenna port, number of layers or number of resource pools of some or all of the resources transmitted in N frequency domain resources, or changing the number of frequency domain resources transmitted in the above-mentioned N frequency domain resources.

[0043] In this implementation, the transmission channel can be switched for frequency domain resources among N frequency domain resources, and transmission can be performed based on the switched transmission channel, thereby further improving the transmission performance of the terminal. For example, on some resources, the transmission channel can be changed from 1 to 2, or the number of antenna ports can be changed from 1 to 2 on some resources, etc.

[0044] As an optional implementation, the number of antenna ports for transmission on the first frequency domain resource is less than or equal to the number of transmission channels of the terminal on the first frequency domain resource, where the first frequency domain resource is any one of the N frequency domain resources.

[0045] The aforementioned first frequency domain resource can be understood as any one of the N frequency domain resources, where the number of antenna ports for transmission on each frequency domain resource is less than or equal to the number of transmit channels for that frequency domain resource. For example, the number of antenna ports in each frequency band, carrier, BWP, or resource pool is less than or equal to the number of Tx in that frequency band, carrier, BWP, or resource pool.

[0046] In this embodiment, each combination of Tx and / or port (or mapping relationship) may include the number of Tx or index of each frequency domain resource, and also the number of antennas or index of each frequency domain resource, wherein the number of antennas of each frequency domain resource in each combination is less than or equal to the number of Tx of that frequency domain resource.

[0047] In this embodiment, since the number of antenna ports for transmission on the first frequency domain resource is less than or equal to the number of transmission channels of the terminal on the first frequency domain resource, each antenna port can correspond to at least one transmission channel, thereby improving the reliability of terminal transmission.

[0048] As an optional implementation, the preset condition includes at least one of the following:

[0049] The terminal has the ability to switch transmission channels for at least a portion of the frequency domain resources in the N frequency domain resources;

[0050] The terminal receives a trigger signaling message to initiate a switch of the transmission channel;

[0051] The transmission completed by the terminal meets the first preset requirement;

[0052] The current transmission performed by the terminal meets the first preset requirement;

[0053] The transmission that the terminal is about to perform meets the second preset requirement;

[0054] The terminal meets the third preset requirement.

[0055] The terminal having transmit channel switching capability on at least some of the N frequency domain resources can mean that it has transmit channel switching capability on each of the N frequency domain resources, or that it has transmit channel switching capability on some of the frequency domain resources.

[0056] The trigger signaling obtained by the aforementioned terminal for triggering the transmission channel switch can be a trigger signaling sent by the network-side device or other SL terminals.

[0057] The transmissions completed by the aforementioned terminal may have been completed before the terminal switched transmission channels.

[0058] The terminal can satisfy the third preset requirement if the terminal's behavior, state, etc., meet the third preset requirement.

[0059] The aforementioned first, second, and third preset requirements may be configured by the network-side equipment or agreed upon by the protocol.

[0060] In one implementation, the first preset requirement includes: the terminal performing transmission through one antenna port in the first frequency domain resource set; and / or

[0061] The second preset requirement includes: the terminal performs transmission through one antenna port in the second frequency domain resource set; and / or

[0062] The third preset requirement includes at least one of the following:

[0063] The terminal does not support, does not perform, does not configure, or does not schedule the transmission of the two antenna ports on each frequency domain resource in the first frequency domain resource set and the second frequency domain resource set.

[0064] The terminal supports, performs, configures, or schedules transmission on only one antenna port on each frequency domain resource in the first and second frequency domain resource sets.

[0065] The first frequency domain resource set may include one or more frequency domain resources, and the second frequency domain resource set may include one or more frequency domain resources.

[0066] The aforementioned first and second frequency domain resource sets may each include different frequency domain resources from the N frequency domain resources;

[0067] Alternatively, the first frequency domain resource set includes a first portion of the frequency domain resources among the N frequency domain resources, the second frequency domain resource set includes a second portion of the frequency domain resources among the N frequency domain resources, and the first portion of the frequency domain resources and the second portion of the frequency domain resources have some overlap.

[0068] For example, the first frequency domain resource set and the second frequency domain resource set are on different P and Q frequency domain resources, respectively, and the P and Q frequency domain resources have no intersection. The union of the first frequency domain resource set and the second frequency domain resource set can be equal to or not equal to the N frequency domain resources.

[0069] Alternatively, the first and second frequency domain resource sets may exist only on P and Q frequency domain resources, respectively, and the P and Q frequency domain resources may have some overlap.

[0070] In this implementation, the terminal's transmission can be performed in the following two ways:

[0071] The terminal cannot transmit simultaneously on different carriers; or...

[0072] The terminal can transmit simultaneously on different carriers.

[0073] The two types mentioned above can be indicated by network parameters.

[0074] In this embodiment, when the terminal has completed, is currently performing, or is about to perform a transmission using only one antenna port, or when the terminal does not support, does not perform, does not configure, or does not schedule transmission using two antenna ports on each frequency resource in the first and second frequency resource sets, or only supports, performs, configures, or schedules transmission using only one antenna port, the terminal can perform transmission in N frequency resources and can perform transmission channel switching for N frequency resources to improve the terminal's transmission performance.

[0075] In another embodiment, the first preset requirement includes: the terminal performs transmission through one antenna port in the first frequency domain resource set; and / or

[0076] The second preset requirement includes: the terminal performs transmission through one or two antenna ports in the second frequency domain resource set; and / or

[0077] The third preset requirement includes at least one of the following:

[0078] The terminal supports, performs, configures, or schedules transmission on at least one frequency domain resource in the second frequency domain resource set;

[0079] The terminal does not support, does not perform, does not configure, or does not schedule transmission on the frequency domain resources in the first frequency domain resource set.

[0080] In this embodiment, the first frequency domain resource set and the second frequency domain resource set mentioned above can be found in the description of the above embodiment. Additionally, in this embodiment, the terminal's transmission can also exist in the following two ways:

[0081] The terminal cannot transmit simultaneously on different carriers; or...

[0082] The terminal can transmit simultaneously on different carriers.

[0083] In this embodiment, when the terminal has completed or is currently performing a transmission using only one antenna port, or when the terminal is about to perform a transmission using one or two antenna ports, or when the terminal supports, performs, configures, or schedules a transmission using two antenna ports on at least one frequency domain resource in the second frequency domain resource set, or does not support, does not perform, does not configure, or does not schedule a transmission using two antenna ports on a frequency domain resource in the first frequency domain resource set, the terminal can perform transmission in N frequency domain resources and can perform transmission channel switching of N frequency domain resources to improve the terminal's transmission performance.

[0084] In another embodiment, the first preset requirement includes: the terminal performs transmission through one or two antenna ports in the first frequency domain resource set; and / or

[0085] The second preset requirement includes: the terminal performs transmission through one antenna port in the second frequency domain resource set; and / or

[0086] The third preset requirement includes at least one of the following:

[0087] The terminal supports, performs, configures, or schedules transmission on at least one frequency domain resource in the first frequency domain resource set;

[0088] The terminal does not support, does not perform, does not configure, or does not schedule transmission on the frequency domain resources in the second frequency domain resource set.

[0089] In this embodiment, the first frequency domain resource set and the second frequency domain resource set mentioned above can be found in the description of the above embodiment. Additionally, in this embodiment, the terminal's transmission can also exist in the following two ways:

[0090] The terminal cannot transmit simultaneously on different carriers; or...

[0091] The terminal can transmit simultaneously on different carriers.

[0092] In this embodiment, when the terminal has completed or is currently transmitting data using one or two antenna ports, or when the terminal is about to transmit data using one antenna port, or when the terminal supports, performs, configures, or schedules transmission using two antenna ports on at least one frequency resource in the first frequency resource set, or when the terminal does not support, does not perform, does not configure, or does not schedule transmission using two antenna ports on frequency resources in the second frequency resource set, the terminal can transmit data in N frequency resources and can perform transmission channel switching of N frequency resources to improve the terminal's transmission performance.

[0093] In another implementation, the first preset requirement includes: the terminal performs transmission through two antenna ports in the first frequency domain resource set; and / or

[0094] The second preset requirement includes: the terminal performs transmission through two antenna ports in the second frequency domain resource set; and / or

[0095] The third preset requirement includes at least one of the following:

[0096] The terminal supports, performs, configures, or schedules transmission on at least one frequency domain resource in the first frequency domain resource set;

[0097] The terminal supports, performs, configures, or schedules transmission on at least one frequency domain resource in the second frequency domain resource set;

[0098] The terminal supports, performs, configures, or schedules transmissions from two antenna ports on the current frequency domain resources.

[0099] In this embodiment, the first frequency domain resource set and the second frequency domain resource set mentioned above can be found in the description of the above embodiment. Additionally, in this embodiment, the terminal's transmission can also exist in the following two ways:

[0100] The terminal cannot transmit simultaneously on different carriers; or...

[0101] The terminal can transmit simultaneously on different carriers.

[0102] The terminal can transmit simultaneously on different carriers.

[0103] In this embodiment, when the terminal has completed or is currently transmitting data using two antenna ports, or when the terminal is about to transmit data using two antenna ports, or when the terminal supports, performs, configures, or schedules the transmission of two antenna ports on at least one frequency domain resource in the first frequency domain resource set, or when the terminal supports, performs, configures, or schedules the transmission of two antenna ports on at least one frequency domain resource in the second frequency domain resource set, the terminal can transmit data in N frequency domain resources and can perform transmission channel switching of N frequency domain resources to improve the terminal's transmission performance.

[0104] As an optional implementation, the terminal supports at least one of the following antenna transmission modes:

[0105] The first mode indicates that only one transmission channel can transmit on one frequency domain resource, or the first mode indicates that only one antenna port can transmit on one frequency domain resource.

[0106] The second mode indicates that transmission through two transmission channels is supported on at least one frequency domain resource, and transmission through only one transmission channel is supported on at least one frequency domain resource; or, the second mode indicates that transmission through two antenna ports is supported on at least one frequency domain resource, and transmission through only one antenna port is supported on at least one frequency domain resource.

[0107] The third mode indicates that transmission through two transmission channels is supported on at least two frequency domain resources, or that transmission through two antenna ports is supported on at least two frequency domain resources.

[0108] The above-mentioned support for transmitting from only one antenna port on at least one frequency domain resource can be expressed as support for transmitting from at most one antenna port on at least one frequency domain resource.

[0109] For example, the first mode, the second mode, and the third mode mentioned above can be represented as follows:

[0110] 1Tx-1Tx means that only one Tx or antenna port transmission can be sent on one frequency band, carrier, BWP or resource pool;

[0111] For 1Tx-2Tx, at least one frequency band, carrier, BWP, or resource pool can transmit 2 Tx or antenna port transmissions, and at least one frequency band, carrier, BWP, or resource pool can only transmit 1 Tx or antenna port transmissions.

[0112] 2Tx-2Tx means that there are at least two frequency bands, carriers, BWPs, or resource pools that can transmit two Tx or antenna ports.

[0113] In this implementation, flexible transmission can be achieved in multiple antenna modes.

[0114] As an optional implementation, the antenna transmission mode supported by the terminal is related to at least one of the following:

[0115] Terminal capabilities; network configuration; and / or,

[0116] At least one of the first preset requirement, the second preset requirement, and the third preset requirement is associated with the antenna transmission mode supported by the terminal.

[0117] In this embodiment, the antenna transmission mode supported by the terminal can be determined based on at least one of the terminal's capabilities and network configuration. Specifically, the first mode, the second mode, and the third mode can be determined based on at least one of the terminal's capabilities and network configuration, so that the antenna transmission mode of the terminal matches the terminal's capabilities and network configuration.

[0118] In addition, the first, second, and third preset requirements can be determined based on the antenna transmission mode, so that the conditions for the terminal to trigger the switching of transmission and transmission channels match the antenna transmission modes supported by the terminal, enabling the terminal to better switch transmission and transmission channels.

[0119] As an optional implementation, when the same antenna port corresponds to different transmission channel combinations after switching, the terminal determines the target transmission channel combination corresponding to the same antenna port based on the first indication information sent by the network side.

[0120] The aforementioned first indication information can be high-level parameter configuration, downlink control information (DCI) indication, or DCI format.

[0121] The above-mentioned determination of the target transmission channel combination corresponding to the same antenna port refers to distinguishing the transmission channel combinations corresponding to the same antenna port in order to determine the target transmission combination corresponding to each antenna port.

[0122] This implementation method can distinguish the corresponding transmission channel combinations by using the first indication information when the same antenna port corresponds to different transmission channel combinations after switching, so as to ensure that each antenna port uses the corresponding transmission channel for transmission and improve the reliability of transmission.

[0123] In this embodiment, the terminal's configuration resources include N frequency domain resources, and the terminal transmits within these N frequency domain resources under preset conditions, where N is an integer greater than 2. The terminal has M transmission channels, or the terminal can transmit simultaneously on at most M transmission channels, where M is a positive integer less than or equal to N. This allows transmission within more than two frequency domain resources, thereby improving the terminal's transmission performance.

[0124] The following example uses frequency domain resources as a band to illustrate the transmission channel switching in the embodiments of this application:

[0125] In the following embodiments, uplink transmission can be divided into Mode 1 and Mode 2 based on whether it supports simultaneous uplink transmission across multiple frequency domains. Mode 1 indicates that uplink transmission cannot occur simultaneously on multiple carriers, while Mode 2 indicates that uplink transmission can occur simultaneously on multiple carriers. Furthermore, N indicates that the terminal is configured with N bands, and M indicates that the terminal has M transmission channels, or that the terminal can transmit simultaneously on a maximum of M transmission channels.

[0127] In this embodiment, when N=3, M=2, and the three carriers are in three bands respectively, the first preset requirement, the second preset requirement, and the third preset requirement in this application embodiment may include at least one combination of Tx and / or antenna port as shown in Table 1, wherein mode 1 and mode 2 are configured or indicated through the network. The number of Tx and the number of ports for carrier 1, carrier 2, and carrier 3 can be as shown in Table 1:

[0130] The possible switching options can be represented by the following tables.

In other words, different cases in the table provided in this application embodiment can be switched to each other.

[0166] When configured as mode 1, and each band can only support, perform, configure, or schedule the transmission of 1 port, when switching between any two bands via 1Tx-1Tx, the terminal cannot transmit on either of the two / any carriers during the switching time.
