Terminal equipment can also be simply referred to as terminal or UE, the meaning of which can be understood by those skilled in the art.
[0030] Access network device 20 is a device deployed in an access network to provide wireless communication functionality to terminal device 10. Access network device 20 may include various forms of macro base stations, micro base stations, relay stations, APs (Access Points), etc. In systems employing different wireless access technologies, the name of the device with access network device functionality may differ; for example, in a 5G NR (New Radio) system, it is called gNodeB or gNB (Next Generation Node B). As communication technologies evolve, the name "access network device" may change. For ease of description, in this embodiment, the aforementioned devices providing wireless communication functionality to terminal device 10 are collectively referred to as access network devices. In some embodiments, a communication relationship can be established between terminal device 10 and core network element 30 through access network device 20.

The terminal device communicates with the network device through the transmission resources (e.g., frequency domain resources, or spectrum resources) on the carrier used by the cell. The cell can be the cell corresponding to the network device (e.g., a base station). The cell can belong to a macro base station or to a base station corresponding to a small cell.

[0035] Before introducing the technical solution of this application, some related technical knowledge involved in this application will be introduced and explained. The following related technologies are optional solutions and can be arbitrarily combined with the technical solutions of the embodiments of this application, all of which fall within the protection scope of the embodiments of this application. The embodiments of this application include at least some of the following contents.
[0036] 1. Sidelink (side-link) relay
[0037] During the standard discussion process, in order to further expand network coverage, improve power efficiency, and support a wider range of applications and services, 3GPP conducted research on NR Sidelink Relay technology, introducing UE-to-Network Relay (U2N Relay) technology. When the link quality between a remote UE and the base station deteriorates, the remote UE can select a suitable relay UE to ensure service continuity through U2N relay technology. The standard discussion involved Layer 3-based relay and Layer 2-based relay transmission.
[0038] 2. Introduction to UE Aggregated Transmission
[0039] With the rapid development of mobile communication technology, users have increasingly higher requirements for data transmission rates and network coverage. Traditional single-user equipment (UE) transmission methods are often limited by factors such as the hardware capabilities, transmit power, number of antennas, and spectrum resources of a single UE when facing high-bandwidth, low-latency services, making it difficult to meet the growing service demands.
[0040] For example, in 5G networks, although the transmission capacity of a single UE has been significantly improved, bottlenecks still exist in some high-demand scenarios, such as high-definition video streaming, virtual reality (VR), augmented reality (AR), and remote control in the industrial Internet of Things (IIoT). Furthermore, in areas with weak network coverage or poor signal, the transmission performance of a single UE will further degrade, resulting in a poor user experience.
[0041] To overcome these limitations, UE aggregation transmission technology emerged. This technology achieves distributed data transmission and power sharing by collaborating and integrating the capabilities of multiple UEs, thereby effectively improving overall transmission performance. For example, through UE aggregation, the data rate for users at the cell edge can be significantly improved, and the uplink rate will also be enhanced to some extent. In addition, UE aggregation can also extend uplink coverage, enabling terminals in areas with deep indoor coverage or weak signal to send data using nearby terminals with better signal, thereby improving the smoothness of services such as live video streaming.
[0042] For Uu-link communication with the gNB, such as uplink transmission, the UE's functionality, features, or operation are limited by factors such as the number of antennas, total available transmit power, specified or mandatory limits on transmit power, and the ability to support operation or communication in a specific mode. For example, some UEs may support carrier aggregation (CA) or dual connectivity (DC). Other factors may additionally or alternatively limit the UE's functionality, features, or operation. These limitations on the UE's functionality, features, or operation, especially those related to Uu-link communication with the gNB, not only directly affect the UE's performance but also broadly impact the performance of the communication system.
[0043] Sidelink relay aims to improve communication quality between remote UEs and base stations. Remote UEs can select suitable relay UEs to ensure service continuity through relay technology. However, sidelink relay only increases coverage. The main difference between UE aggregation and sidelink relay is that UE aggregation focuses more on physical layer enhancement, increasing transmit power relative to individual UE transmissions and increasing the total number of radio frequency links or transmission layers. Therefore, a crucial issue in UE aggregation is how to instruct network devices to perform UE aggregation transmission, and how to determine the capabilities of UEs in aggregation transmission relative to independent transmissions.
[0044] Please refer to Figure 2, which shows a flowchart of an aggregation transmission method provided in one embodiment of this application. The method is performed by a terminal device. The method includes the following step 210.
[0045] Step 210: The terminal device sends first information, which is used to determine the multiple terminal devices participating in the aggregated transmission. Aggregated transmission means that the information sent by multiple terminal devices is combined to obtain second information. The multiple terminal devices include a first terminal device and one or more second terminal devices. One or more second terminal devices are used to assist the first terminal device in performing aggregated transmission.
[0046] In some embodiments, aggregated transmission refers to the merging of information sent by multiple terminal devices to obtain second information. In aggregated transmission, the data of the first terminal device can be transmitted simultaneously with the assistance of one or more second terminal devices. Without increasing the power of the first terminal device or the power of one or more second terminal devices, aggregated transmission of multiple terminal devices can improve the total data transmission power, improve uplink coverage, and increase system throughput.
[0047] In some embodiments, the second information is information to be sent by the first terminal device, and the first terminal device and one or more second terminal devices respectively send part or all of the second information. The first terminal device and one or more second terminal devices send part or all of the second information through different transmission resources, which include one or more of time domain resources, frequency domain resources, and spatial domain resources.
[0048] In some embodiments, multiple terminal devices are aggregated to form a third terminal device, which then sends the second information. In some embodiments, the third terminal device is a virtual terminal device aggregated from multiple terminal devices. In some embodiments, the third terminal device may possess all or some of the capabilities of the multiple terminal devices. The third terminal device will be described in detail in subsequent embodiments.
[0049] In some embodiments, the second information may be data information, signaling or control information, or a combination of data information and signaling or control information; this application does not limit this.
[0050] In some embodiments, the terminal device performing step 210 may be a first terminal device or a second terminal device. The first terminal device is the terminal device that needs to aggregate transmission, and the second terminal device is a terminal device capable of providing assistance in aggregate transmission.
[0051] In one example, the terminal device performing step 210 is a first terminal device, and the first information includes one or more of the following:
[0052] The first instruction information includes the identification information of N second terminal devices, where N is a positive integer;
[0053] The second instruction information includes an aggregated transmission request, which is used to request aggregated transmission.
[0054] In some embodiments, the identification information of the second terminal device includes one or more of the following: the ID, sequence, Radio Network Temporary Identifier (RNTI), and Temporary Mobile Subscription Identifier (TMSI) of the second terminal device.
[0055] In some embodiments, the first indication information indicates the identification information of N second terminal devices, used to inform the network device that the terminal device expects to identify one or more second terminal devices from among the N second terminal devices for aggregated transmission. Of course, the one or more second terminal devices ultimately assisting in aggregated transmission can be selected entirely from the N second terminal devices, partially from the N second terminal devices, or not selected from the N second terminal devices at all. The one or more second terminal devices ultimately assisting in aggregated transmission are determined by the network device.
[0056] In some embodiments, the first terminal device sends an aggregated transmission request, and the network device determines whether the first terminal device should perform aggregated transmission.
[0057] In another example, the terminal device performing step 210 is a second terminal device, and the first information includes third indication information, which includes an assist aggregation transmission request, used to indicate whether the second terminal device supports assist aggregation transmission.
[0058] In some embodiments, a terminal device sends first information, and after receiving the first information, the network device determines multiple terminal devices to perform aggregated transmission. In some embodiments, whether a terminal device performs aggregated transmission is determined based on one or more of the following: first indication information sent by a first terminal device, second indication information sent by a first terminal device, third indication information sent by a second terminal device, and comprehensive information corresponding to each of the multiple terminal devices. The comprehensive information corresponding to a terminal device is determined based on a combination of one or more of the terminal device's transmission requirements and its capability set. How the network device determines the multiple terminal devices to perform aggregated transmission will be described in detail in subsequent embodiments.
[0059] In some embodiments, the aggregation transfer request and the assisting aggregation transfer request can be indicated by a single information field. For example, one bit can be used to indicate this; a value of 1 indicates an aggregation transfer request, and a value of 0 indicates an assisting aggregation transfer request. Alternatively, a value of 0 indicates an aggregation transfer request, and a value of 1 indicates an assisting aggregation transfer request.
[0060] In some embodiments, the aggregation transfer request and the assisting aggregation transfer request are indicated by different information fields. For example, one bit indicates the aggregation transfer request, and another bit indicates the assisting aggregation transfer request.
[0061] In some embodiments, the first information is further used to indicate the aggregation transmission scheme supported by the terminal device. In some embodiments, the aggregation transmission scheme includes one or more of the following: SFN (Single Frequency Network), SDM (Spatial Division Multiplexing), and FDM (Frequency Division Multiplexing).
[0062] In some embodiments, the first information is carried in one or more of the following signals or channels: measurement report, capability report, PUCCH (Physical Uplink Control Channel), CSI (Channel State Information), and MAC CE (Medium Access Control Element).
[0063] For example, the first information is carried in a measurement report, which includes a first information field, which is dedicated to carrying the first information.
[0064] For example, the first information is carried in the capability report, which includes indication information related to aggregated transmissions. This indication information is capability information, which can be reported as a separate capability IE or together with other capability IEs.
[0065] For example, the first information is carried in the PUCCH and reported. For instance, the first information is carried in the UCI (Uplink Control Information).
[0066] For example, the first information is carried in the CSI report. For instance, the first information can be carried in CSI part I or CSI part II.
[0067] For example, the first information is carried and reported in MAC CE.
[0068] It should be noted that, in the embodiments of this application, when a terminal device is mentioned alone, it can be implemented as a first terminal device, a second terminal device, or a third terminal device, and the name can be replaced based on its implementation. When the first information is mentioned alone, it can be implemented as any one of the first instruction information, the second instruction information, and the third instruction information; it is simply referred to as the first information collectively. In addition, the third terminal device in the embodiments of this application can also be replaced by the first terminal device and / or one or more second terminal devices.
[0069] The technical solution provided in this application embodiment involves a terminal device sending first information to a network device, which then determines multiple terminal devices to perform aggregated transmission based on the first information. This enables the network device to obtain relevant information about the aggregated transmission of the terminal devices, providing an implementation method for aggregated transmission of the terminal devices. Based on aggregated transmission, the terminal devices can increase the transmit power relative to a single terminal device, and also increase the total number of radio frequency links or transmission layers.
[0070] Please refer to Figure 3, which shows a flowchart of an aggregation transmission method provided in one embodiment of this application. The method is performed by a network device. The method includes the following step 310.
[0071] Step 310: The network device receives first information, which is used to determine multiple terminal devices participating in aggregated transmission.

[0074] In some embodiments, multiple terminal devices are aggregated to form a third terminal device, which then sends the second information.

Based on aggregated transmission, the terminal devices can increase the transmit power relative to a single terminal device, and also increase the total number of radio frequency links or transmission layers.
[0096] Regarding whether to perform aggregated transport, and the configuration of aggregated transport.
[0097] 1. Network devices determine whether to perform aggregated transmission.
[0098] In some embodiments, whether the terminal device performs aggregated transmission is determined based on one or more of the following:
[0099] The first instruction information sent by the first terminal device includes the identification information of N second terminal devices, where N is a positive integer.
[0100] The second indication information sent by the first terminal device includes an aggregated transmission request, which is used to request aggregated transmission.
[0101] The third indication information sent by the second terminal device includes an assist aggregation transmission request, which is used to indicate whether the second terminal device supports assist aggregation transmission.
[0102] The comprehensive information corresponding to multiple terminal devices is determined based on a combination of one or more of the terminal device's transmission requirements and its capability set.
[0103] Method 1: The network device determines that the first terminal device and one or more second terminal devices can perform aggregated transmission based on the identification information of N second terminal devices included in the first instruction information sent by the first terminal device. In some embodiments, the one or more second terminal devices may be selected entirely from the N second terminal devices, partially from the N second terminal devices, or not selected at all from the N second terminal devices. For example, the network device may determine all N second terminal devices as second terminal devices participating in aggregated transmission. For example, the network device may select one or more second terminal devices from the N second terminal devices to participate in aggregated transmission.
[0104] Method 2: The network device determines that at least one second terminal device can perform aggregated transmission based on the assist aggregation transmission request included in the third indication information sent to the network device by at least one second terminal device, but this method may not be able to determine the paired first terminal device.
[0105] In some embodiments, the network device may determine the pairing of aggregated transmissions. For example, the network device determines whether to perform aggregated transmissions and the pairing of aggregated transmissions based on aggregated information corresponding to multiple terminal devices.
[0106] Method 3: The network device determines that the first terminal device and at least one second terminal device can perform aggregated transmission based on the second instruction information sent by the first terminal device and the third instruction information sent by at least one second terminal device. For example, the network device receives the second instruction information sent by terminal device 1 and the third instruction information sent by terminal devices 2 and 3, and determines that terminal devices 1, 2, and 3 will perform aggregated transmission.
[0107] Method 4: The network device determines the multiple terminal devices to perform aggregated transmission based on the first indication information sent by the first terminal device and the third indication information sent by at least one second terminal device. For example, for the N second terminal devices indicated in the first indication information, if the network device receives the third indication information sent by the i-th second terminal device, then the i-th second terminal device is determined to be one of the multiple terminal devices to perform aggregated transmission; if the network device does not receive the third indication information sent by the i-th second terminal device, then the i-th second terminal device is determined not to perform aggregated transmission, where i is an integer less than or equal to N.
[0108] Method 5: The network device determines multiple terminal devices to perform aggregated transmission based on the first indication information, the second indication information sent by the first terminal device, and the third indication information sent by at least one second terminal device. For example, if the network device receives the second indication information sent by the first terminal device, it determines that the first terminal device performs aggregated transmission. For example, for the N second terminal devices indicated in the first indication information, if the network device receives the third indication information sent by the i-th second terminal device, it determines the i-th second terminal device as one of the multiple terminal devices to perform aggregated transmission; if the network device does not receive the third indication information sent by the i-th second terminal device, it determines that the i-th second terminal device does not perform aggregated transmission, where i is an integer less than or equal to N.
[0109] Method 6: The network device determines the multiple terminal devices to perform aggregated transmission based on the comprehensive information corresponding to each of the multiple terminal devices. In some embodiments, the network device can determine which terminal devices can perform aggregated transmission based on the comprehensive information corresponding to each of the multiple terminal devices, and assign them as either the first terminal device or the second terminal device.
[0110] In some embodiments, method 6 can be combined with methods 1 to 5 to obtain new methods. These methods will not be described in detail here, and the combined methods should also fall within the protection scope of the embodiments of this application.
[0111] 2. Instruct the terminal device to perform aggregated transmission.
[0112] (1) Indicates whether to perform aggregated transfer.
[0113] In some embodiments, after determining whether a terminal device performs aggregated transmission, the network device sends third information, which is used to indicate whether the terminal device performs aggregated transmission.
[0114] In some embodiments, the terminal device receives third information, which instructs the terminal device whether to perform aggregated transmission. Exemplarily, a first terminal device receives the third information, which instructs the first terminal device to perform aggregated transmission. Exemplarily, a second terminal device receives the third information, which instructs the second terminal device to perform aggregated transmission.
[0115] In some embodiments, the third information can be a single bit used to indicate whether the terminal device performs aggregated transmission. For example, a value of 1 for the first information indicates that the terminal device performs aggregated transmission, and a value of 0 for the first information indicates that the terminal device does not perform aggregated transmission. Alternatively, a value of 0 for the first information indicates that the terminal device performs aggregated transmission, and a value of 1 for the first information indicates that the terminal device does not perform aggregated transmission.
[0116] In some embodiments, the network device sends third information to multiple terminal devices performing aggregated transmission. In some embodiments, the third information also carries the aggregated transmission configuration of the terminal devices.
[0117] In some embodiments, the network device may broadcast third information, in which case the third information may also include identification information of multiple terminal devices performing aggregated transmission. In some embodiments, if there are multiple groups of terminal devices performing aggregated transmission, the third information may also include pairing information of the terminal devices performing aggregated transmission.
[0118] (2) Indicate aggregated transport configuration
[0119] In some embodiments, the network device further sends fifth information to the terminal device, the fifth information being used to instruct the terminal device on aggregated transmission configuration. In some embodiments, the terminal device receives the fifth information, the fifth information being used to instruct the terminal device on aggregated transmission configuration.
[0120] In some embodiments, the aggregated transport configuration includes one or more of the following:
[0121] Aggregated transmission scheme;
[0122] Multiple terminal devices;
[0123] The third terminal device participating in the aggregated transmission is a virtual terminal device obtained by aggregating multiple terminal devices participating in the aggregated transmission.
[0124] In some embodiments, the aggregation transmission scheme includes one or more of the following: SFN, SDM, and FDM.
[0125] In some embodiments, the third and fifth information may be sent simultaneously or sequentially, and this application does not limit this. In some embodiments, the third and fifth information may be carried in the same signal or channel or in different signals or channels.
[0126] Using the above method, after identifying multiple terminal devices that will perform aggregated transmission, the network device can also instruct the terminal devices whether to participate in aggregated transmission and configure the aggregated transmission, so that the aggregated transmission can be executed correctly.
[0127] Regarding how to indicate the capability set of terminal devices
[0128] In some embodiments, in order to ensure the correct execution of aggregated transmission, the terminal device also needs to report its own capability set to assist the network device in scheduling or resource allocation.
[0129] In some embodiments, the terminal device sends fourth information, which indicates the capability set of the terminal device and / or the capability set of a third terminal device, wherein the third terminal device is a virtual terminal device obtained by aggregating multiple terminal devices participating in the aggregated transmission. Accordingly, the network device receives the fourth information.
[0130] In one example, the terminal device is a first terminal device, which sends fourth information, which is used to indicate the capability set of the first terminal device and / or the capability set of the third terminal device.
[0131] In another example, the terminal device is a second terminal device, which sends fourth information indicating the capability set of the second terminal device and / or the capability set of the third terminal device.
[0132] In some embodiments, the capability set of the third terminal device is determined based on the capability sets corresponding to each of the multiple terminal devices. In this case, the fourth information does not need to carry the capability set of the third terminal device, so the fourth information can be sent before or after the terminal device receives the third and / or fifth information. For example, the fourth information can be sent simultaneously with the first information.
[0133] In some embodiments, the value range of the first portion of the capabilities in the capability set of the third terminal device is the union of the value ranges of the first portion of the capabilities in the capability sets corresponding to the multiple terminal devices; and / or,
[0134] The value range of the second part of the capability set of the third terminal device is the minimum value range among the value ranges of the second part of the capability set corresponding to each of the multiple terminal devices.
[0135] In some embodiments, the capability set includes one or more of the following capabilities: carrier aggregation capability, terminal-inherent capability, signal or channel processing capability, and timing-related capability.
[0136] For example, the first part of the capability includes carrier aggregation capability and terminal-specific capabilities. For instance, carrier aggregation capability: if a first terminal device supports aggregated transmission on a first carrier set, and at least one second terminal device supports aggregated transmission on a second carrier set, then the third terminal device can support aggregated transmission on both the first and second carrier sets. For instance, some terminal-specific capabilities include the number of transmit links, the number of receive links, etc. If the number of transmit / receive links of the first terminal device is a first number, and the number of transmit / receive links of the at least one second terminal device is a second number, then the number of transmit / receive links of the third terminal device is the sum of the first and second numbers.
[0137] For example, the second part of the capability includes signal or channel processing capability and timing-related capability. For example, signal or signal processing capability includes the ability to process channels, signals, search space, etc., such as DCI processing capability. If a first terminal device supports processing a first number of downlink DCIs and a second number of uplink DCIs within a processing time, and at least one second terminal device supports processing a third number of downlink DCIs and a fourth number of uplink DCIs within a processing time, then the DCI processing capability supported by the third terminal device is a minimum set, supporting the processing of min{first number, third number} of downlink DCIs and min{second number, fourth number} of uplink DCIs within a processing time.
[0138] For example, timing-related capabilities include handover time capability, reporting time capability, and processing time capability. For instance, if the timing-related capability of the first terminal device requires the first time, and the timing-related capability of at least one second terminal device requires the second time, then the timing-related capability of the third terminal device is within the minimum value range, i.e., the required time is min{first time, second time}.
[0139] In some embodiments, the capability set of the third terminal device is reported separately. For example, the fourth information is used to indicate the capability set of the third terminal device. In this case, the fourth information is sent after the terminal device receives the third information and / or the fifth information. In this case, the third terminal device reports individual UE capabilities. As the terminal device for aggregated transmission, the third terminal device sends its capability set to the network device before determining to perform aggregated transmission. This allows the network device to directly schedule the third terminal device for aggregated transmission based on the capability set, without needing to comprehensively consider the capabilities of the first terminal device and at least one second terminal device, which is beneficial for network device scheduling.
[0140] In some embodiments, the capability set of the third terminal device includes one or more of the following capabilities: carrier aggregation capability, terminal-inherent capabilities, signal or channel processing capabilities, and timing-related capabilities. In some embodiments, the capabilities included in the capability set of the third terminal device may differ from the capabilities reported in the capability set of the first terminal device or the capability sets of one or more second terminal devices. For example, carrier aggregation capability: the first terminal device supports aggregated transmission on a first carrier set, at least one second terminal device supports aggregated transmission on a second carrier set, and the third terminal device transmits on a third carrier set, the third carrier set including a portion of the first carrier set and a portion of the second carrier set. For example, the timing-related capabilities of the first terminal device require a first time, the timing-related capabilities of at least one second terminal device require a second time, and the timing-related capabilities of the third terminal device require a third time, and the third time is not derived from the first and second times.
[0141] Please refer to Figure 4, which shows a schematic diagram of an aggregated transmission method provided in one embodiment of this application. Please refer to Figure 5, which shows a flowchart of an aggregated transmission method provided in another embodiment of this application.

[0143] First, the first terminal device and at least one second terminal device send their respective capability sets to the network device.
[0144] The first terminal device and at least one second terminal device send aggregation transmission-related indication information to the network device. The first indication information, the second indication information, and the third indication information can also be sent through the capability set, so there is no need to send them separately.
[0145] Once aggregated transmission is determined, the third-party terminal device can send the aggregated transmission capability set to the network device. The network device can determine the aggregated transmission capability set based on the individual capability sets of each terminal device, or it can determine the aggregated transmission capability set based on the capability set of the third-party terminal device; this step is optional.
[0146] The network device determines the aggregated transmission and sends the configuration and scheduling information of the third terminal device. The third terminal device then communicates with the network device in accordance with the aggregated transmission method.
