[0020] The application scenario of this application will be described below.

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

[0022] The number of terminals 10 is typically plural, and one or more terminals 10 may be distributed within a cell managed by each network device 20. The terminals 10 may include handheld devices with various wireless communication capabilities, in-vehicle devices, wearable devices, computing devices or other processing devices connected to wireless modems, and various types of user equipment (UE), mobile stations (MS), etc. For ease of explanation, in the embodiments of the present application, the above-mentioned devices will be collectively referred to as terminals.

[0023] The network device 20 is a device located in an access network and provides wireless communication functions for the terminal 10. The network device 20 may include various types of macro base stations, micro base stations, relay stations, access points, etc. In systems employing different radio access technologies, the name of a device having a network device function may differ. For example, in a 5G NR system, it is called a gNodeB or gNB. As communication technologies evolve, the name "network device" may change. For ease of explanation, in the embodiments of the present application, devices providing wireless communication functions for the terminal 10 are collectively referred to as network devices. A connection can be established between the network device 20 and the terminal 10 via an air interface, and communication including signaling and data interactions is performed through this connection. There may be multiple network devices 20, and two adjacent network devices 20 may communicate with each other via a wired or wireless method. The terminal 10 can switch between different network devices 20, i.e., establish connections with different network devices 20.

[0024] The "5G NR system" in the embodiments of the present application may be referred to as a 5G system or an NR system, and those skilled in the art will understand the meaning thereof. The technical solutions described in the embodiments of the present application may be applied to the 5G NR system, and may also be applied to subsequent evolution systems of the 5G NR system.

[0025] FIG. 2 is a flowchart of an uplink MIMO transmission capability reporting and receiving method provided by an exemplary embodiment of the present application, which is applied to the terminal and network device shown in FIG. 1, and the method includes at least some of the content of the following steps:

[0026] In step 201, a terminal sends first signaling and second signaling to a network device, where 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.

[0027] In an embodiment of the present 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 first signaling and second signaling to the network device, and indicates the uplink MIMO transmission capability supported by the terminal through the first signaling and the second signaling.

[0028] Here, 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, where the first uplink MIMO transmission capability is equal to or greater than the second uplink MIMO transmission capability.

[0029] In the embodiment of the present application, the first signaling and the second signaling can be distinguished into two signalings by the names of the first signaling and the second signaling.

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

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

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

[0033] In an embodiment of the present application, a network device receives first signaling and second signaling, and determines a maximum uplink MIMO transmission capability supported by a terminal through the first signaling and the second signaling. When configuring the number of layers for actual uplink MIMO transmission, the network device completes the configuration of the number of uplink MIMO transmission layers using the determined maximum uplink MIMO transmission capability supported by the terminal as a limit.

[0034] It should be noted that the steps performed by the terminal can be realized as one step individually, and the steps performed by the network device can be implemented as one step individually.

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

[0036] 2 illustrates a terminal reporting its uplink MIMO transmission capability. In addition to the embodiment illustrated in FIG. 2, the terminal may transmit the first signaling and the second signaling if it determines that it satisfies certain conditions, which are described below.

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

[0038] In order to enable a terminal to support a larger uplink MIMO transmission capability, the terminal introduces a 6-way or 8-way radio frequency channel, that is, when a terminal introduces a 6-way radio frequency channel, the maximum uplink MIMO transmission capability supported by the terminal is 6 layers, while when an 8-way radio frequency channel is introduced, the maximum uplink MIMO transmission capability supported by the terminal is 8 layers.

[0039] In some embodiments, referring to FIG. 3, the method includes step 2011.

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

[0041] In the embodiment of the present application, since the maximum uplink MIMO transmission capability supported by the terminal is 6 layers or 8 layers, and the second signaling cannot indicate the 6-layer or 8-layer uplink MIMO transmission capability supported by the terminal, the terminal needs to send the first signaling and the second signaling to the network device to ensure that the terminal reports the maximum uplink MIMO transmission capability supported by the terminal to the network device.

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

[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 is 6 layers, or the maximum number of layers indicated by the terminal via the first signaling is 8 layers, or the maximum number of layers indicated by the terminal via the first signaling is another number of layers, and is not limited to this in the embodiments of the present application.

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

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

[0047] For example, the maximum number of layers indicated by the terminal via the second signaling is four layers, or the maximum number of layers indicated by the terminal via the second signaling is two layers, or the maximum number of layers indicated by the terminal via the first signaling is another number of layers, and is not limited to this in the embodiments of the present application.

[0048] It should be noted that the embodiments of the present application merely take as an example the case where the terminal transmits the first signaling and the second signaling when the maximum uplink MIMO transmission capability supported by the terminal is 6 or 8 layers. In another embodiment, when the terminal supports a transmission capability of a new number of uplink MIMO layers, the terminal transmits the first signaling and the second signaling to the network device.

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

[0050] The first point that needs to be explained is that the embodiments of the present application only take the first signaling and the second signaling as an example, and in another embodiment, the first signaling and the second signaling are RRC (Radio Resource Control) signaling.

[0051] The second point that needs to be explained is that the embodiment of the present application only takes the number of uplink MIMO layers as an example, in another embodiment, the number of uplink MIMO layers of the present application can also be the number of uplink RANK.

[0052] In the method provided by the embodiments of the present application, if the terminal's supported uplink MIMO transmission capability is 6 layers or 8 layers, the terminal reports its supported uplink MIMO transmission capability through the first signaling and the second signaling, and supports the terminal to report a larger uplink MIMO transmission capability to match the actual system uplink transmission capability, supports the network to schedule a higher data layer, and achieves a higher uplink transmission rate.

[0053] The above-described embodiments may be divided into new embodiments or may be combined with each other to form new embodiments, but the present application does not limit the division method or combination method.

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

[0055] In the embodiment of the present application, the first signaling and the second signaling indicate two different uplink MIMO transmission capabilities, that is, 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 six or eight, and the number of layers corresponding to the second uplink MIMO transmission capability is up to four.

[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. Alternatively, the number of layers corresponding to the first uplink MIMO transmission capability and the second uplink MIMO transmission capability may be other numbers of layers, and is not limited in the embodiments of the present application.

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

[0059] Alternatively, this first signaling may be referred to as an uplink feature set for each component carrier (CC) with a version number v18xy.

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

[0061] Optionally, this second signaling may be referred to as an uplink feature set for each CC.

[0062] The format and parameter code of the first signaling are as follows:

number

[0063] The format and parameter code of the first signaling will be briefly explained below.

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

[0065] For the first signaling, the first signaling is signaling with a version number v18xy, and the 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 of each set is an integer from 1 to 8.

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

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

[0069] The above-described embodiments may be divided into new embodiments or may be combined with each other to form new embodiments, but the present application does not limit the division method or combination method.

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

[0071] In the embodiments of the present application, the first signaling and the second signaling may indicate two different uplink MIMO transmission capabilities, or the first signaling and the second signaling may indicate two identical uplink MIMO transmission capabilities, i.e., 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 eight layers and the second uplink MIMO transmission capability is up to four layers.

[0073] For example, the number of layers corresponding to the first uplink MIMO transmission capability is six, and the number of layers corresponding to the second uplink MIMO transmission capability is four. Alternatively, the number of layers corresponding to the first uplink MIMO transmission capability is eight, and the number of layers corresponding to the second uplink MIMO transmission capability is two. Alternatively, the number of layers corresponding to the first uplink MIMO transmission capability is four, and the number of layers corresponding to the second uplink MIMO transmission capability is four. The number of layers corresponding to the first uplink MIMO transmission capability and the second uplink MIMO transmission capability may be other numbers, and is not limited in the embodiments of the present application.

[0074] Note that 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 the present 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 signaling and the second signaling actually indicate the same transmission capability, that is, the content contained in the first signaling and the second signaling is also the same.

[0076] The format and parameter code of the first signaling are as follows:

number

[0077] The format and parameter code of the first signaling will be briefly explained below.

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

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

[0080] The maximum sounding signal resource of each set is an integer from 1 to 8.

[0081] In non-codebook precoding, the maximum number of MIMO layers supported by a 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 layer, 2 layers, 3 layers, 4 layers, 6 layers, or 8 layers.

[0083] The above-described embodiments may be divided into new embodiments or may be combined with each other to form new embodiments, but the present application does not limit the division method or combination method.

[0084] In the embodiment shown in Fig. 2, it is described that the network device determines the maximum uplink MIMO transmission capability supported by the terminal based on the first signaling and the second signaling. Based on the embodiment shown in Fig. 2, the network device determines the maximum uplink MIMO transmission capability supported by the terminal based on whether it can recognize the first signaling, and two cases are described below.

[0085] First case: When 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 a limit on the number of layers of the actual uplink MIMO transmission.

[0086] In the embodiments of the present 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 only be able to recognize the second signaling and not be able to recognize 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 it can recognize the first signaling.

[0087] After the 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 the first signaling is equal to or greater than 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 of the actual uplink MIMO transmission.

[0088] For example, if 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, and if the network device can recognize the first signaling, the network device ignores the second signaling and determines that the limit on the number of layers for actual uplink MIMO transmission is 6. Alternatively, if 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, and if the network device can recognize the first signaling, the network device ignores the second signaling and determines that the limit on the number of layers for actual uplink MIMO transmission is 8.

[0089] In some embodiments, after the network device receives the first signaling and the second signaling, it can obtain the version number of the first signaling and the version number of the second signaling, and determine whether the network device can recognize the first signaling and the second signaling based on the obtained version number of the first signaling and the version number of the second signaling.

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

[0091] Second case: When the network device does not recognize the first signaling, it determines the number of layers corresponding to 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.

[0092] In an embodiment of the present application, after a network device receives the first signaling and the second signaling, if the network device cannot recognize the first signaling but can recognize the second signaling, the network device ignores the first signaling and determines the number of layers corresponding to 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.

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

[0094] In some embodiments, after the network device receives the first signaling and the second signaling, it can obtain the version number of the first signaling and the version number of the second signaling, and determine whether the network device can recognize the first signaling and the second signaling based on the obtained version number of the first signaling and the version number of the second signaling.

[0095] In the method provided by the embodiments of the present application, when the network device does not recognize the first signaling, it can also determine the second uplink MIMO transmission capability indicated by the second signaling as the limit of the number of layers of the actual uplink MIMO transmission, thereby preventing the terminal from being 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-described embodiments may be divided into new embodiments or may be combined with each other to form new embodiments, but the present application does not limit the division method or combination method.

[0097] 2 illustrates that the network device determines the maximum uplink MIMO transmission capability supported by the terminal based on the first signaling and the second signaling. Based on the embodiment illustrated in FIG. 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. Referring to FIG. 4, the method includes the following step 204:

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

[0099] In an embodiment of the present application, a network device can determine the maximum uplink MIMO transmission capability supported by a terminal, and when the network device sets the number of layers of actual uplink MIMO transmission for the terminal, it can refer to the determined maximum uplink MIMO transmission capability supported by the terminal, and the number of layers of actual 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 number of layers of the actual uplink MIMO transmission set by the network device may be 4 layers, or the number of layers of the actual uplink MIMO transmission set by the network device may be 6 layers, or the number of layers of the actual uplink MIMO transmission set by the network device may be other values, which are not limited in the embodiments of the present application.

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

[0102] The above-described embodiments may be divided into new embodiments or may be combined with each other to form new embodiments, but the present application does not limit the division method or combination method.

[0103] FIG. 5 is a block diagram of an uplink MIMO transmission capability reporting device provided by an exemplary embodiment of the present application. Referring to FIG. 5, the device includes: a transmitting module 501 for transmitting first signaling and second signaling to a network device, where 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 capacity is greater than or equal to the second uplink MIMO transmission capacity.

[0104] In the device provided by the embodiments of the present application, the terminal reports its own uplink MIMO transmission capability via first signaling and second signaling. Since the uplink MIMO transmission capability indicated by the first signaling is equal to or greater than the uplink MIMO transmission capability indicated by the second signaling, the terminal supports a larger uplink MIMO transmission capability and can also report a larger uplink MIMO transmission capability via the first signaling, thereby supporting the terminal to report a larger uplink MIMO transmission capability to match the actual system uplink transmission capability, supporting the network to schedule a higher data rank, and achieving a higher uplink transmission rate.
