[0020] Hereinafter, the application scenarios of this application will be described.

[0021] FIG. 1 is a block diagram of a communication system provided by an exemplary embodiment of this application, and this communication system can include a terminal 10 and a network device 20.

[0022] The number of terminals 10 is usually plural, and one or more terminals 10 may be distributed within a cell managed by each network device 20. The terminal 10 can include various handheld devices with wireless communication functions, in-vehicle devices, wearable devices, computing devices or other processing devices connected to a wireless modem, and various forms of user equipment (UE), mobile stations (MS), etc. For the sake of easy explanation, in the embodiments of this application, the devices described above are collectively referred to as terminals.

[0023] The network device 20 is a device deployed in an access network that provides wireless communication functionality for the terminal 10. The network device 20 can include various forms of macro base stations, micro base stations, relay stations, access points, etc. In systems employing different wireless access technologies, the name of the device with network device functionality may differ; for example, in a 5G NR system, it is called a gNodeB or gNB.

[0024] In the embodiments of this application, the “5G NR system” may also be called a 5G system or an NR system, but those skilled in the art will understand the meaning. The technical solutions described in the embodiments of this application may be applied to 5G NR systems, or to subsequent evolutionary systems of 5G NR systems.

[0025] Figure 2 is a flowchart of an uplink MIMO transmission capability reporting and receiving method provided by an exemplary embodiment of the present application, applicable to the terminal and network device shown in Figure 1, and the method includes at least a portion of the following sticks.

[0026] In step 201, the terminal transmits a first signaling signal and a second signaling signal to the network device, the first signaling signaling a first uplink MIMO transmission capability supported by the terminal and the second signaling signaling a second uplink MIMO transmission capability supported by the terminal.

[0027] In the embodiments of this application, the terminal itself has uplink MIMO transmission capability, and before the terminal communicates with the network device, the terminal needs to report its own uplink MIMO transmission capability, and the terminal sends a first signaling and a second signaling to the network device, which indicates the uplink MIMO transmission capability supported by the terminal via the first signaling and the second signaling.

[0028] Here, the first signaling indicates a first uplink MIMO transmission capability supported by the terminal, the second signaling indicates a second uplink MIMO transmission capability supported by the terminal, and the first uplink MIMO transmission capability is greater than or equal to the second uplink MIMO transmission capability.

[0029] In the embodiments of this application, the first signaling and the second signaling can be distinguished as two separate signalings by their names, the first signaling and the second signaling.

[0030] In step 202, the network device receives the first signaling and the second signaling transmitted from the terminal.

[0031] After receiving the first and second signaling signals, the network device determines the uplink MIMO transmission capability supported by the terminal based on these signals.

[0032] In step 203, the network device determines the limit on the number of layers for actual uplink MIMO transmission based on the maximum uplink MIMO transmission capability supported by the terminal.

[0033] In the embodiments of this application, the network device receives a first signaling signal and a second signaling signal, determines the maximum uplink MIMO transmission capability supported by the terminal via the first and second signaling signals, and when the network device configures the actual number of uplink MIMO transmission layers, it completes the configuration of the number of uplink MIMO transmission layers with the determined maximum uplink MIMO transmission capability supported by the terminal as a limit.

[0034] Furthermore, steps performed by terminals can be implemented as individual steps, and steps performed by network devices can be implemented as individual steps.

[0035] In the method provided by the embodiments of this application, the terminal reports its own uplink MIMO transmission capability via a first signaling and a second signaling, and since the uplink MIMO transmission capability indicated by the first signaling is greater than or equal to the uplink MIMO transmission capability indicated by the second signaling, the terminal supports a larger uplink MIMO transmission capability and can also report a higher MIMO transmission capability via the first signaling, supporting the terminal reporting a larger uplink MIMO transmission capability to match the actual system uplink transmission capability, supporting the network to schedule higher data levels, and achieving higher uplink transmission speeds.

[0036] Figure 2 illustrates how a terminal reports its own uplink MIMO transmission capability. Next, in addition to the embodiment shown in Figure 2, the terminal transmits a first signaling and a second signaling if it determines that it meets certain conditions, which are described below.

[0037] In the embodiments of this application, the maximum uplink MIMO transmission capability supported by the terminal is 6 layers or 8 layers.

[0038] To enable the terminal to support a greater uplink MIMO transmission capability, the terminal may implement 6-way or 8-way radio frequency channels. Specifically, if the terminal implements 6-way radio frequency channels, the maximum uplink MIMO transmission capability supported by the terminal will be 6 layers, while if it implements 8-way radio frequency channels, the maximum uplink MIMO transmission capability supported by the terminal will be 8 layers.

[0039] In some embodiments, referring to Figure 3, this method includes step 2011.

[0040] In step 2011, if the maximum uplink MIMO transmission capability supported by the terminal is layer 6 or layer 8, the first signaling and the second signaling are sent to the network device.

[0041] In the embodiments of this application, the maximum uplink MIMO transmission capability supported by the terminal is 6 or 8 layers, and the second signaling cannot indicate the 6 or 8 layer uplink MIMO transmission capability supported by the terminal. Therefore, in order to ensure that the terminal reports to the network device the maximum uplink MIMO transmission capability supported by itself, the terminal needs to transmit the first signaling and the second signaling to the network device.

[0042] In some embodiments, the maximum number of layers indicated by the first signaling is 6, or the maximum number of layers indicated by the first signaling is 8.

[0043] If the maximum number of layers indicated by the first signaling is 6, it also indicates that the maximum number of layers corresponding to the first uplink MIMO transmission capability indicated by the terminal via the first signaling is 6. If the maximum number of layers indicated by the first signaling is 8, it indicates that the maximum number of layers corresponding to the first uplink MIMO transmission capability indicated by the terminal via the first signaling is 8.

[0044] For example, the maximum number of layers indicated by the terminal via the first signaling may be 6 layers, or 8 layers, or any other number of layers, and is not limited to the embodiments of this application.

[0045] In some other embodiments, the maximum number of layers indicated by the second signaling is four.

[0046] If the maximum number of layers indicated by the second signaling is 4, this indicates that the maximum number of layers corresponding to the second uplink MIMO transmission capability indicated by the terminal via the second signaling is 4.

[0047] For example, the maximum number of layers indicated by the terminal via the second signaling may be 4, or 2, or the maximum number of layers indicated by the terminal via the second signaling may be any other number, and is not limited to the embodiments of this application.

[0048] The embodiments of this application merely illustrate the transmission of the first and second signaling when the maximum uplink MIMO transmission capability supported by the terminal is 6 or 8 layers. In another embodiment, the first and second signaling are transmitted to the network device when the terminal supports a new uplink MIMO layer capacity.

[0049] For a terminal, the maximum number of MIMO layers indicated by the second signaling is limited, and if the terminal supports the transmission capability of a new uplink MIMO layer, it cannot use the second signaling to report the new uplink MIMO layer that it supports. Therefore, if the terminal supports the transmission capability of a new uplink MIMO layer, it sends the first and second signaling to the network device, and since the first uplink MIMO transmission capability indicated by the first signaling is greater than or equal to the second uplink MIMO transmission capability indicated by the second signaling, the first signaling can be used to indicate the new uplink MIMO transmission capability supported by the terminal.

[0050] The first point that needs to be explained is that the embodiments of this application only illustrate the first and second signaling as examples. In other embodiments, the first and second signaling are RRC (Radio Resource Control) signaling.

[0051] The second point that needs to be explained is that the embodiments of this application merely illustrate the number of uplink MIMO layers as an example. In another embodiment, the number of uplink MIMO layers in this application may also be the number of uplink ranks.

[0052] In the methods provided by embodiments of this application, the terminal reports the uplink MIMO transmission capability it supports via first and second signaling when the supported uplink MIMO transmission capability is 6 or 8 layers, supports the terminal reporting a larger uplink MIMO transmission capability to match the actual system uplink transmission capability, supports the network scheduling higher data layers, and achieves higher uplink transmission speeds.

[0053] The above embodiments may be divided into new embodiments, or they may be combined to form new embodiments; however, this application does not limit the method of division or combination.

[0054] Based on the embodiment shown in Figure 2, the first uplink MIMO transmission capability does not include the second uplink MIMO capability.

[0055] In the embodiments of this application, the first signaling and the second signaling indicate two different uplink MIMO transmission capabilities, namely, the first uplink MIMO transmission capability is higher than the second uplink MIMO transmission capability.

[0056] In some embodiments, the number of layers corresponding to the first uplink MIMO transmission capability is 6 or 8, and the number of layers corresponding to the second uplink MIMO transmission capability is up to 4.

[0057] For example, the number of layers corresponding to the first uplink MIMO transmission capability is 6, and the number of layers corresponding to the second uplink MIMO transmission capability is 4. Alternatively, the number of layers corresponding to the first uplink MIMO transmission capability is 8, and the number of layers corresponding to the second uplink MIMO transmission capability is 2. Or, the number of layers corresponding to the first uplink MIMO transmission capability and the second uplink MIMO transmission capability may be any other number, and is not limited to the embodiments of this application.

[0058] In some embodiments, the first signaling is FeatureSetUplinkPerCC-v18xy.

[0059] Selectively, this first signaling may be called the uplink feature set for each component carrier (CC), with version number v18xy.

[0060] In some embodiments, the second signaling is FeatureSetUplinkPerCC.

[0061] Selectively, this second signaling may also be called the uplink feature set for each CC.

[0062] The format and parameter codes for the first signaling are as follows:

number

[0063] The format and parameter codes for the first signaling described above are briefly explained below.

[0064] The first signaling is a set of features for each uplink carrier sequence, and the size of the first signaling is between 1 and the maximum value of each feature.

[0065] For the first signaling, this first signaling is the signaling with version number v18xy, and this first signaling indicates that the maximum number of MIMO layers supported by the physical uplink shared channel (PUSCH) is the number of uplink MIMO layers.

[0066] The maximum sounding signal resource for each set is an integer between 1 and 8.

[0067] In non-codebook pre-recording, the maximum number of MIMO layers supported by PUSCH is the number of uplink MIMO layers.

[0068] Here, the number of MIMO layers indicated by the first signaling may be 6 or 8.

[0069] The above embodiments may be divided into new embodiments, or they may be combined to form new embodiments; however, this application does not limit the method of division or combination.

[0070] Based on the embodiment shown in Figure 2, the first uplink MIMO transmission capability includes the second uplink MIMO capability.

[0071] In the embodiments of this application, the first and second signaling may indicate two different uplink MIMO transmission capabilities, or they may indicate two identical uplink MIMO transmission capabilities. That is, the first uplink MIMO transmission capability may be higher than the second uplink MIMO transmission capability, or the first uplink MIMO transmission capability may be equal to the second uplink MIMO transmission capability.

[0072] In some embodiments, the first uplink MIMO transmission capability is up to 8 layers, and the second uplink MIMO transmission capability is up to 4 layers.

[0073] For example, the number of layers corresponding to the first uplink MIMO transmission capability is 6, and the number of layers corresponding to the second uplink MIMO transmission capability is 4. Alternatively, the number of layers corresponding to the first uplink MIMO transmission capability is 8, and the number of layers corresponding to the second uplink MIMO transmission capability is 2. Alternatively, the number of layers corresponding to the first uplink MIMO transmission capability is 4, and the number of layers corresponding to the second uplink MIMO transmission capability is 4. The number of layers corresponding to the first and second uplink MIMO transmission capabilities may be other numbers, and are not limited to the embodiments of this application.

[0074] Furthermore, the first uplink MIMO transmission capability is the same as the second uplink MIMO transmission capability, and the content included in the first signaling is the same as the content included in the second signaling.

[0075] In the embodiments of this application, when the first uplink MIMO transmission capability indicated by the first signaling and the second uplink MIMO transmission capability indicated by the second signaling are the same, the first and second signalings actually indicate the same transmission capability, i.e., the content contained in the first and second signalings is also the same.

[0076] The format and parameter codes for the first signaling are as follows:

number

[0077] The format and parameter codes for the first signaling described above are briefly explained below.

[0078] The first signaling is a set of features for each uplink carrier sequence, and the size of the first signaling is between 1 and the maximum value of each feature.

[0079] For the first signaling, this first signaling is the signaling with version number v18xy, and this first signaling indicates that the maximum number of MIMO layers supported by the physical uplink shared channel is the uplink MIMO layer number.

[0080] The maximum sounding signal resource for each set is an integer between 1 and 8.

[0081] In non-codebook pre-recording, the maximum number of MIMO layers supported by PUSCH (Physical Uplink Shared Channel) is the number of uplink MIMO layers.

[0082] Here, the number of MIMO layers indicated by the first signaling may be 1, 2, 3, 4, 6, or 8.

[0083] The above embodiments may be divided into new embodiments, or they may be combined to form new embodiments; however, this application does not limit the method of division or combination.

[0084] In the embodiment shown in Figure 2, it is explained that a network device determines the maximum uplink MIMO transmission capability supported by the terminal based on a first signaling signal and a second signaling signal. Based on the embodiment shown in Figure 2, the network device determines the maximum uplink MIMO transmission capability supported by the terminal based on whether or not it can recognize the first signaling signal, and this will be explained in two cases below.

[0085] In the first case, if the network device recognizes the first signaling, it determines the number of layers corresponding to the first uplink MIMO transmission capability indicated by the first signaling as the limit on the number of layers for the actual uplink MIMO transmission.

[0086] In the embodiments of this application, for network devices with different configurations, the network device may be able to recognize the first signaling and also be able to recognize the second signaling, or the network device may be able to recognize only the second signaling and not the first signaling, and therefore the network device determines the limit on the number of layers of the actual uplink MIMO transmission based on whether or not it can recognize the first signaling.

[0087] After a network device receives the first signaling and the second signaling, if the network device can recognize the first signaling and the first uplink MIMO transmission capability indicated by this first signaling is greater than or equal to the second uplink MIMO transmission capability indicated by the second signaling, the network device can ignore the second signaling and determine the number of layers corresponding to the first uplink MIMO transmission capability indicated by the first signaling as the limit on the number of layers for actual uplink MIMO transmission.

[0088] For example, if the first uplink MIMO transmission capability indicated by the first signaling corresponds to 6 layers, and the second uplink MIMO transmission capability indicated by the second signaling corresponds to 4 layers, and the network device can recognize the first signaling, it will ignore the second signaling and determine that the actual limit on the number of layers for uplink MIMO transmission is 6 layers. Alternatively, if the first uplink MIMO transmission capability indicated by the first signaling corresponds to 8 layers, and the second uplink MIMO transmission capability indicated by the second signaling corresponds to 4 layers, and the network device can recognize the first signaling, it will ignore the second signaling and determine that the actual limit on the number of layers for uplink MIMO transmission is 8 layers.

[0089] In some embodiments, after a network device receives a first signaling signal and a second signaling signal, it can obtain the version numbers of the first signaling signal and the second signaling signal, and based on the obtained version numbers of the first signaling signal and the second signaling signal, it can determine whether or not the network device can recognize the first signaling signal and the second signaling signal.

[0090] In the method provided by the embodiments of this application, if a network device determines that it can recognize a first signaling, it determines that the uplink MIMO transmission capability indicated by the first signaling is greater than or equal to the uplink MIMO transmission capability indicated by the second signaling, and therefore determines the uplink MIMO transmission capability indicated by the first signaling as the limit on the number of layers of actual uplink MIMO transmission, and the service transmission speed is improved if the maximum uplink MIMO transmission capability supported by the terminal is improved.

[0091] Second case: If the network device does not recognize the first signaling, the number of layers corresponding to the second uplink MIMO transmission capability indicated by the second signaling is determined as the limit on the number of layers for the actual uplink MIMO transmission.

[0092] In the embodiments of this application, after a network device has received a first signaling signal and a second signaling signal, if the network device is unable to recognize the first signaling signal but can recognize the second signaling signal, the network device ignores the first signaling signal and determines the number of layers corresponding to the second uplink MIMO transmission capability indicated by the second signaling signal as the limit on the number of layers for the actual uplink MIMO transmission.

[0093] For example, the number of layers corresponding to the first uplink MIMO transmission capability indicated by the first signaling is 6, and the number of layers corresponding to the second uplink MIMO transmission capability indicated by the second signaling is 4. Since the network device cannot recognize the first signaling but can recognize the second signaling, the network device ignores the first signaling and determines that the actual limit on the number of layers for uplink MIMO transmission is 4. Alternatively, the number of layers corresponding to the first uplink MIMO transmission capability indicated by the first signaling is 8, and the number of layers corresponding to the second uplink MIMO transmission capability indicated by the second signaling is 4. Since the network device cannot recognize the first signaling but can recognize the second signaling, the network device ignores the first signaling and determines that the actual limit on the number of layers for uplink MIMO transmission is 4.

[0094] In some embodiments, after a network device receives a first signaling signal and a second signaling signal, it can obtain the version numbers of the first signaling signal and the second signaling signal, and based on the obtained version numbers of the first signaling signal and the second signaling signal, it can determine whether or not the network device can recognize the first signaling signal and the second signaling signal.

[0095] In the methods provided by embodiments of this application, if the first signaling is not recognized, the network device may also determine the second uplink MIMO transmission capability indicated by the second signaling as the limit on the number of layers of the actual uplink MIMO transmission, preventing cases where the terminal is unable to report its own uplink MIMO transmission capability, ensuring that the network device knows the uplink MIMO transmission capability supported by the terminal, and further ensuring the transmission of services.

[0096] The above embodiments may be divided into new embodiments, or they may be combined to form new embodiments; however, this application does not limit the method of division or combination.

[0097] In the embodiment shown in Figure 2, it is explained that a network device determines the maximum uplink MIMO transmission capability supported by the terminal based on a first signaling and a second signaling. Based on the embodiment shown in Figure 2, the network device can also set the number of layers for uplink MIMO transmission based on the maximum uplink MIMO transmission capability supported by the terminal, and referring to Figure 4, this method includes the following step 204.

[0098] In step 204, the network device sets the actual number of layers for uplink MIMO transmission, and the actual number of layers for uplink MIMO transmission is less than or equal to the number of layers corresponding to the maximum uplink MIMO transmission capability supported by the terminal.

[0099] In the embodiments of this application, a network device can determine the maximum uplink MIMO transmission capability supported by a terminal, and when the network device sets the actual number of layers for uplink MIMO transmission to a terminal, it can refer to the determined maximum uplink MIMO transmission capability supported by the terminal, and the actual number of layers for uplink MIMO transmission set by the network device is less than or equal to the number of layers corresponding to the maximum uplink MIMO transmission capability supported by the terminal.

[0100] For example, if the number of layers corresponding to the maximum uplink MIMO transmission capability determined by the network device is 6 layers, the actual number of layers for uplink MIMO transmission set by the network device may be 4 layers, or 6 layers, or other values, and are not limited to the embodiments of this application.

[0101] In the method provided by the embodiments of this application, the network device sets the number of uplink MIMO transmission layers for the terminal based on the maximum uplink MIMO transmission capability supported by the terminal, prevents the number of uplink MIMO transmission layers set by the network device from exceeding the maximum number of uplink MIMO transmission layers supported by the terminal, thereby ensuring uplink MIMO transmission for the terminal and improving the speed of terminal transmission.

[0102] The above embodiments may be divided into new embodiments, or they may be combined to form new embodiments; however, this application does not limit the method of division or combination.

[0103] Figure 5 is a block diagram of an uplink MIMO transmission capability reporting device provided by an exemplary embodiment of the present application, and referring to Figure 5, this device is A transmitting module 501 for transmitting a first signaling and a second signaling to a network device, wherein the first signaling indicates a first uplink MIMO transmission capability supported by the terminal, and the second signaling indicates a second uplink MIMO transmission capability supported by the terminal, The first uplink MIMO transmission capability is greater than or equal to the second uplink MIMO transmission capability.

[0104] In the apparatus provided by the embodiment of this application, the terminal reports its own uplink MIMO transmission capability via a first signaling and a second signaling, and since the uplink MIMO transmission capability indicated by the first signaling is greater than or equal to the uplink MIMO transmission capability indicated by the second signaling, the terminal supports a larger uplink MIMO transmission capability and can also report a higher uplink MIMO transmission capability via the first signaling, supporting the terminal to report a larger uplink MIMO transmission capability to match the actual system uplink transmission capability, supporting the network to schedule higher data levels, and achieving a higher uplink transmission speed.

[0105] In some embodiments, the maximum uplink MIMO transmission capability supported by the terminal is 6 or 8 layers.

[0106] In some embodiments, the first uplink MIMO transmission capability includes a second uplink MIMO transmission capability.

[0107] In some embodiments, the first uplink MIMO transmission capability is the same as the second uplink MIMO transmission capability, and the content included in the first signaling is the same as the content included in the second signaling.

[0108] In some embodiments, the maximum number of layers indicated by the first signaling is 6, or the maximum number of layers indicated by the first signaling is 8.

[0109] In some embodiments, the maximum number of layers indicated by the second signaling is four.
