[0051] By way of example and not limitation, in this embodiment, the terminal device can also be a wearable device. Wearable devices, also known as wearable smart devices, are a general term for devices that utilize wearable technology to intelligently design and develop everyday wearables, such as glasses, gloves, watches, clothing, and shoes. Wearable devices are portable devices that are worn directly on the body or integrated into the user's clothing or accessories. Wearable devices are not merely hardware devices, but also achieve powerful functions through software support, data interaction, and cloud interaction. Broadly speaking, wearable smart devices include those that are feature-rich, large in size, and can achieve complete or partial functions without relying on a smartphone, such as smartwatches or smart glasses, as well as those that focus on a specific type of application function and require the use of other devices such as smartphones, such as various smart bracelets and smart jewelry for vital sign monitoring.

Network devices can be access points (APs) in WLANs, base stations (BTSs) in GSM or CDMA, base stations (NodeBs, NBs) in WCDMA, evolved base stations (eNBs or eNodeBs) in LTE, relay stations or access points, or in-vehicle devices, wearable devices, and network devices (gNBs) in NR networks, or network devices in future evolved PLMN networks, etc.
[0053] In this embodiment, the network device provides services to the cell, and the terminal device communicates with the network device through the transmission resources (e.g., frequency domain resources, or spectrum resources) used by the cell. The cell can be the cell corresponding to the network device (e.g., base station). The cell can belong to a macro base station or to a base station corresponding to a small cell. The small cell can include: metro cell, micro cell, pico cell, femto cell, etc. These small cells have the characteristics of small coverage area and low transmission power, and are suitable for providing high-speed data transmission services.
[0054] It should be understood that the term "instruction" mentioned in the embodiments of this application can be a direct instruction, an indirect instruction, or an indication of a relationship. For example, A instructing B can mean that A directly instructs B, such as B being able to obtain information through A; it can also mean that A indirectly instructs B, such as A instructing C, so B can obtain information through C; or it can mean that there is a relationship between A and B.
[0055] In the description of the embodiments of this application, the term "correspondence" may indicate that there is a direct or indirect correspondence between two things, or that there is an association between two things, or that there is a relationship of instruction and being instructed, configuration and being configured, etc.

Optionally, the wireless communication system 100 may include multiple network devices 110, and the coverage area of each network device 110 may include other numbers of terminal devices 120. This application embodiment does not limit this.
[0058] Optionally, the wireless communication system 100 may also include other network entities such as a Mobility Management Entity (MME) and an Access and Mobility Management Function (AMF), which are not limited in this application embodiment.
[0059] It should be understood that the terms "system" and "network" are often used interchangeably in this document. The term "and / or" in this document merely describes the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A alone, A and B simultaneously, or B alone. Furthermore, the character " / " in this document generally indicates that the preceding and following related objects have an "or" relationship.
[0060] Figure 2 This is a schematic flowchart of a transmission method 200 according to an embodiment of this application. The method can optionally be applied to... Figure 1 The system shown is not limited to this. The method includes at least a portion of the following.
[0061] S210, the terminal device (e.g., the aforementioned UE or other communication device) determines a second real PUSCH for multiplexing the UCI based on the required symbol length for carrying uplink control signaling UCI and / or the first real physical uplink shared channel PUSCH for multiplexing the UCI.
[0062] The first real PUSCH may target a different first receiver and / or a different first beam direction than the second real PUSCH targets a different second receiver and / or a different second beam direction.

This at least solves the technical problem of the lack of relevant technical solutions in technologies such as 5G. It should be noted that the technical problem described herein is only an example, and this application can actually solve other technical problems as well; therefore, it should not be taken as a limitation of this application.
[0066] Optionally, the receiving end may include a Transmitter-Receiver Point (TRP). Alternatively, the receiving end may also include a non-TRP receiving end.
[0067] Optionally, there can be a one-to-one correspondence between the receiver and the beam direction. For example, the first beam direction can correspond to the first receiver, and the second beam direction can correspond to the second receiver. Of course, the receiver and the beam direction can have a one-to-one correspondence, or they can not.
[0068] It should be noted that "first" and "second" here are not used to indicate which one is being referred to specifically.
[0069] Optionally, such as Figure 3 As shown, the transmission method according to the embodiments of this application may further include:
[0070] S209, the terminal device can determine the required symbol length for carrying UCI based on the symbol length of the nominal PUSCH.
[0071] For example, a method for determining the required symbol length for carrying UCI based on the symbol length of the nominal PUSCH can be found in, for example, 3GPP TS 38.213 V16.5.0 (2021-03). It should be noted that this application is not limited to this, and other methods may also be used to determine the required symbol length for carrying UCI.
[0072] Optionally, such as Figure 4 As shown, the terminal device in S210, based on the required symbol length for carrying uplink control signaling (UCI) and / or the first real physical uplink shared channel (PUSCH) for multiplexing the UCI, determines the second real PUSCH for multiplexing the UCI, which may include:
[0073] S2101, based on the required symbol length for carrying the UCI and / or the first real PUSCH, determine the symbol length that the UCI will occupy.
[0074] In this application, "the UCI will occupy symbol length" can mean that the UCI will occupy symbol length in the second real PUSCH.
[0075] Optionally, such as Figure 4 As shown, S2101's determination of the symbol length to be occupied by the UCI based on the required symbol length for carrying the UCI and / or the first real PUSCH may include:
[0076] If the determined symbol length required to carry the UCI is greater than the symbol length occupied by the first real PUSCH, then the symbol length to be occupied by the UCI is determined to be the symbol length occupied by the first real PUSCH; otherwise, the symbol length to be occupied by the UCI is determined to be the symbol length required to carry the UCI.
[0077] Optionally, such as Figure 4 As shown, the terminal device in S210, based on the required symbol length for carrying uplink control signaling (UCI) and / or the first real physical uplink shared channel (PUSCH) for multiplexing the UCI, determines a second real PUSCH for multiplexing the UCI, and may further include:
[0078] S2102, the terminal device determines each real PUSCH corresponding to the second receiver and / or the second beam direction.
[0079] Optionally, such as Figure 4 As shown, the terminal device in S210, based on the required symbol length for carrying uplink control signaling (UCI) and / or the first real physical uplink shared channel (PUSCH) for multiplexing the UCI, determines a second real PUSCH for multiplexing the UCI, and may further include:

[0082] Select one of the real PUSCHs corresponding to the second beam direction or the second receiver, whose symbol length is greater than or equal to the symbol length required by the UCI, as the second real PUSCH.

[0084] Optionally, the terminal device in S210, based on the required symbol length for carrying uplink control signaling (UCI) and / or the first real physical uplink shared channel (PUSCH) for multiplexing the UCI, determines a second real PUSCH for multiplexing the UCI, which may include:
[0085] The first real PUSCH among those corresponding to the second beam direction or the second receiver, whose symbol length is greater than or equal to the symbol length to be occupied by the UCI, is selected as the second real PUSCH.
[0086] The symbol length required for the UCI is obtained based on the required symbol length for carrying the UCI and / or the symbol length occupied by the first real PUSCH.
[0087] Optionally, the terminal device in S210, based on the required symbol length for carrying uplink control signaling (UCI) and / or the first real physical uplink shared channel (PUSCH) for multiplexing the UCI, determines a second real PUSCH for multiplexing the UCI, which may include:
[0088] The real PUSCH with the largest symbol length among all the real PUSCHs corresponding to the second beam direction or the second receiver is selected as the second real PUSCH.
[0089] Optionally, the terminal device in S210, based on the required symbol length for carrying uplink control signaling (UCI) and / or the first real physical uplink shared channel (PUSCH) for multiplexing the UCI, determines a second real PUSCH for multiplexing the UCI, which may include:
[0090] If, among the real PUSCHs corresponding to the second beam direction or the second receiver, there is no real PUSCH whose occupied symbol length is greater than or equal to the symbol length required by the UCI, the real PUSCH with the largest occupied symbol length is selected from among the real PUSCHs corresponding to the second beam direction or the second receiver as the second real PUSCH.
[0091] The symbol length required for the UCI is obtained based on the required symbol length for carrying the UCI and / or the symbol length occupied by the first real PUSCH.
[0092] Optionally, the transmission method according to the embodiments of this application may further include:
[0093] The terminal device updates the symbol length of the first real PUSCH to the symbol length of the second real PUSCH.
[0094] Optionally, such as Figure 5 As shown, the transmission method according to the embodiments of this application may further include:
[0095] S201, The terminal device receives the configuration regarding the type of uplink PUSCH retransmission.
[0096] Optionally, such as Figure 5 As shown, the transmission method according to the embodiments of this application may further include:
[0097] S202, the terminal device receives a downlink control signaling (DCI) indication, which triggers repeated transmission of PUSCH based on multiple beam directions and / or multiple receivers.
[0098] Optionally, the transmission method according to the embodiments of this application may further include:
[0099] If the terminal device receives a configuration of type B regarding the type of uplink PUSCH retransmission, the terminal device determines the symbol length occupied by the nominal PUSCH based on the downlink control signaling (DCI) indication; and
[0100] Based on the determined symbol length occupied by the nominal PUSCH, the symbol length occupied by the corresponding real PUSCH and the beam direction and / or receiver corresponding to each real PUSCH are determined.
[0101] To reduce latency, 3GPP Release 16 further enhanced uplink transmission by introducing a piggybacking retransmission mechanism. The piggybacking retransmission mechanism has the following main characteristics:
[0102] 1) Adjacent repeated transmission resources are connected end-to-end in the time domain;
[0103] 2) Resources scheduled in one go can span time slots, which ensures that services arriving later in the time slot can also be allocated sufficient resources or be scheduled in real time.
[0104] 3) The number of repetitions is indicated dynamically to adapt to dynamic changes in service and channel environment;
[0105] 4) Time-domain resource allocation is used to indicate the time-domain resources for the first repeated transmission. The time-domain resources for the remaining transmissions will be determined based on the time-domain resources of the first repeated transmission and information such as uplink and downlink transmission direction configurations. Furthermore, each repeated transmission occupies consecutive symbols, such as... Figure 6 As shown. In Figure 6 In this context, the symbol "DL" represents the downlink.
[0106] The uplink transmission enhancement time-domain resource indication can follow the 3GPP Release 15 time-domain resource indication mechanism, where higher-layer signaling configures multiple time-domain resource locations, and physical-layer signaling indicates one of these locations. In Release 15, each time-domain resource location configured by higher-layer signaling uses the SLIV (Start and Length Indicator Value) method. However, for uplink transmission enhancement, each time-domain resource location configured by higher-layer signaling includes three information fields: start symbol, time-domain resource length, and repetition count.
[0107] The aforementioned uplink repetitive transmission method is Type B PUSCH repetitive transmission. In Release 16, while introducing Type B PUSCH repetitive transmission, the slot-level repetitive transmission of Release 15 was also enhanced, meaning the number of repetitive transmissions can be dynamically indicated; this is called Type A PUSCH repetitive transmission. Type A and Type B PUSCH repetitive transmissions can be determined through higher-layer signaling configuration.
[0108] The resource indication method for repeated transmissions specifies the time-domain resource range for each repeated transmission. However, within this time-domain resource range, there may be some symbols that cannot be used for uplink transmission, such as downlink symbols and symbols used for periodic uplink probe signal transmission. Therefore, the actually usable uplink transmission resources need to be further defined. In the uplink transmission enhancements of R16, two types of time-domain resources are defined:
[0109] 1) Nominal PUSCH retransmission: This can be determined by the resource allocation indication information of the retransmission. Different nominal PUSCH retransmissions have the same symbol length. Nominal PUSCH retransmission is used to determine TBS (Transport Block Set), uplink power control, and UCI multiplexing resources, etc.
[0110] 2) True PUSCH Repeat Transmission: Within the time-domain resources determined by the resource allocation indication information used for repeat transmission, unusable symbols are removed to obtain the time-domain resources available for uplink transmission each time. The symbol lengths of different true PUSCH repeat transmissions are not necessarily the same. True PUSCH repeat transmission is used to determine DMRS (Demodulation Reference Signal) symbols, actual transmission rate, RV (Redundancy Version), and UCI multiplexing resources, etc.
[0111] UCI may include Channel State Information (CSI) and / or Hybrid Automatic Repeat Request (HARQ) acknowledgment (HARQ-ACK), etc.
[0112] For example, when UCI is CSI, and the uplink transmission enhancement is configured as PUSCH repetition transmission type B, if, for example, aperiodic CSI overlaps and intersects with PUSCH, aperiodic CSI can be multiplexed only on the actual PUSCH, for example, the first symbol with a length greater than 1, and the symbol length used for the aperiodic CSI transmission portion can be obtained based on the nominal length of the PUSCH retransmission and / or other relevant configurations.
[0113] Optionally, such as Figure 5 As shown, the transmission method according to the embodiments of this application may further include:
[0114] S203, the terminal device receives a UCI, which is triggered by downlink control signaling (DCI).
[0115] Optionally, as mentioned above, the UCI received by the terminal device may overlap or intersect with the PUSCH in terms of time domain resources.
[0116] Optionally, such as Figure 5 As shown, the transmission method according to the embodiments of this application may further include:
[0117] S211, the terminal device transmits UCI in the determined second real PUSCH.
[0118] Optionally, the type of UCI may include at least one of the following: periodic UCI; aperiodic UCI; quasi-periodic UCI.
[0119] Optionally, the UCI includes Channel State Information (CSI) and / or Hybrid Automatic Repeat reQuest (HARQ) Acknowledgment (HARQ-ACK), etc.
[0120] Optionally, the transmission method according to the embodiments of this application may further include:
[0121] Demodulation of UCI is performed on resources where the terminal device transmits PUSCH via at least the first and second receiving ends and / or at least the first and second beam directions.
[0122] Optionally, the transmission method according to the embodiments of this application may further include:
[0123] The terminal device determines the receiver and / or beam direction corresponding to each real PUSCH based on the beam mapping pattern.
[0124] Specifically, during repeated PUSCH transmissions, the time-domain position of sending the first real PUSCH used to carry UCI is earlier than the time-domain position of sending the second real PUSCH used to carry UCI.
[0125] Therefore, it is possible to transmit a UCI on a first PUSCH for the first receiver and / or beam direction before transmitting a UCI on a second PUSCH for the second receiver and / or beam direction.
[0126] Optionally, the transmission method according to the embodiments of this application may further include:
[0127] The terminal device determines the required symbol length for carrying the UCI based on the content of the UCI.
[0128] Here, the UCI content may include relevant information such as CSI and / or HARQ-ACK. In this application, the symbol length required to be transmitted on the PUSCH can be determined based on this relevant information.
[0129] Optionally, the symbol length of the first real PUSCH and / or the second real PUSCH can be greater than 1.
[0130] The above describes the transmission method according to this application. This method can support the transmission of UCI across multiple receivers in different PUSCHs, thereby addressing technical issues such as the lack of relevant technical solutions in 5G technology.
[0131] To make this application easier to understand, the following will provide a more specific description through some examples.
[0132] Figure 7 A transmission method according to another embodiment of this application is shown, which may include the following steps.
[0133] S310, the network device may demodulate uplink control signaling UCI on resources that transmit physical uplink shared channel (PUSCH) through at least first and second receivers and / or at least first and second beam directions, including determining a second real PUSCH for multiplexing the UCI based on the required symbol length for carrying the UCI and / or a first real PUSCH for multiplexing the UCI.
[0134] The first real PUSCH may target a different first receiver and / or a different first beam direction than the second real PUSCH targets a different second receiver and / or a different second beam direction.
[0135] In this application, by determining the second real PUSCH for multiplexing the UCI based on the required symbol length for carrying uplink control signaling (UCI) and / or the first real physical uplink shared channel (PUSCH) for multiplexing the UCI, it is possible to support carrying UCI in different PUSCHs for multiple receivers. This at least solves the technical problem of the lack of relevant technical solutions in technologies such as 5G. It should be noted that the technical problem described herein is only an example, and this application can actually solve other technical problems as well; therefore, it should not be taken as a limitation of this application.
[0136] Optionally, such as Figure 8 As shown, the transmission method according to the embodiments of this application may further include:
[0137] S309, the network device determines the required symbol length for carrying UCI based on the symbol length of the nominal PUSCH.

[0139] S3101, based on the required symbol length for carrying the UCI and / or the first real PUSCH, determine the symbol length that the UCI will occupy.

[0307] Example
[0308] The following two examples will be given to illustrate the technical solution of this application more clearly and comprehensively.
[0309] Assuming that the network side (network device side) is configured to repeat PUSCH transmission, where the parameter for the repeat transmission is 4*8 (i.e., the number of repeat transmissions is 4, the nominal PUSCH length is 8, and the starting position is the 4th OFDM symbol), the terminal side (terminal device side) can determine the actual PUSCH repeat transmission based on the slot boundary and / or other configurations.
[0310] like Figure 16 The example shown has 5 real PUSCH duplicate transmissions.
[0311] On the terminal side, the target receiver and / or beam direction (e.g., TRP) for each real PUSCH can be determined based on the beam mapping pattern indicated by the network side. Assuming real PUSCH 1 and real PUSCH 2 correspond to receiver 1 and / or beam direction 1 on the network side, respectively (e.g., they could correspond to target TRP 1), then real PUSCH 3 and 4 correspond to receiver 2 and / or beam direction 2 on the network side, respectively (e.g., they could correspond to target TRP 2), and real PUSCH 5 can correspond to receiver 1 or beam direction 1 on the network side (e.g., it could correspond to target TRP 1). The terminal side can determine, for example, the time-domain resource occupation of 7 OFDM symbols required for UCI (e.g., aperiodic CSI) based on the real PUSCH 1 of the first receiver and / or beam direction, and the terminal side can select real PUSCH 4 as the PUSCH for aperiodic CSI multiplexing in the second receiver and / or beam direction (i.e., the second real PUSCH) based on these 7 OFDM symbols. The terminal can perform aperiodic CSI multiplexing on the second real PUSCH.
[0312] For example, if the network side is configured to repeat PUSCH transmission, the terminal side can determine the target receiver and / or beam direction (e.g., TRP) for each real PUSCH transmission based on the beam mapping mode indicated by the network side. Assume that real PUSCH 1 (length 5) and real PUSCH 2 (length 4) correspond to receiver 1 and / or beam direction 1 (corresponding to target TRP 1) on the network side, respectively. Real PUSCH 3 and 4 (both length 4) both correspond to receiver 2 and / or beam direction 2 (corresponding to target TRP 2) on the network side. Then, the terminal side can, for example, calculate the time-domain resource requirement of 4 OFDM symbols for aperiodic CSI based on real PUSCH 1 at receiver 1 and / or beam direction 1. Based on these 4 OFDM symbols, the terminal side can select real PUSCH 3 as the PUSCH for aperiodic CSI multiplexing at receiver 2 and / or beam direction 2 (i.e., the second real PUSCH), and the terminal side can perform aperiodic CSI multiplexing on this PUSCH.
