     DETAILED DESCRIPTION 
     The technical solutions of embodiments of the present disclosure will be clearly and completely described below with reference to the drawings of embodiments of the present disclosure, apparently, the described embodiments are some embodiments of the present disclosure, but are not all the embodiments. Based on the embodiments of the present disclosure, all other embodiments derived by a person of ordinary skill in the art without any creative efforts shall fall within the scope of the present disclosure. 
     Referring to  FIG. 1 ,  FIG. 1  is a schematic diagram of a network structure to which some embodiments of the present disclosure are applicable. As shown in  FIG. 1 , user equipment (UE)  11  and a network-side device  12  are included. The user equipment  11  may be a UE-side device such as a mobile phone, a tablet personal computer, a laptop computer, a personal digital assistant (PDA), a mobile Internet device (MID), or a wearable device. It should be noted that a specific type of the user equipment  11  is not limited in embodiments of the present disclosure. The network-side device  12  may be a base station, such as, a macro station, an LTE eNB, or a 5G NR NB; the network-side device  12  may also be a small station, such as a low power node (LPN), a pico station, or a femto station, or the network-side device  12  may be an access point (AP); the base station may also be a network node composed of a central unit (CU) and a plurality of transmission reception points (TRP) managed and controlled by the CU. It should be noted that, a specific type of the network-side device  12  is not limited in the embodiments of the present disclosure. 
     Referring to  FIG. 2 ,  FIG. 2  is a flowchart of a method for determining a bundling size provided in some embodiments of the present disclosure. As shown in  FIG. 2 , the method includes the following steps. 
     Step  201 , reporting, by user equipment, capability information to a network-side device, wherein the capability information is used to indicate whether the user equipment supports one-PRB bundling, and receiving a bundling size set configured by the network-side device for the user equipment according to the capability information, wherein supporting the one-PRB bundling indicates that a turn-off of a PRB bundling function is supported. 
     That supporting the one-PRB bundling indicates that a turn-off of a PRB bundling function is supported may be understood as: the user equipment supports not implementing a bundling of multiple PRBs, instead, the user equipment uses individual PRB for channel estimation separately, or the user equipment uses different precoding for different PRBs. Of course, if the user equipment supports a PRB bundling, the user equipment also supports a multi-PRB bundling, that is, the PRB bundling function is not turned off. 
     No support for the one-PRB bundling may be understood as: a turn-off of the PRB bundling function is not supported, then the user equipment does not support using individual PRB for channel estimation separately, or the user equipment only supports a bundling of multiple PRBs. 
     After receiving the capability information, the network-side device may configure different bundling size sets according to whether the user equipment supports the PRB bundling or not. The bundling size set may include multiple bundling sizes, to adapt to different communication scenarios, services, and so on. 
     In addition, after receiving the bundling size set, the user equipment may select a bundling size from the bundling size set for data transmission. For example, in a case that the network-side device turns off a function of dynamic bundling size adjustment, the user equipment autonomously selects a bundling size from the bundling size set for data transmission. Optionally, the user equipment receives indication information sent by the network-side device and selects a bundling size from the bundling size set according to the indication information for data transmission. For example, when the network-side device turns on the function of dynamic bundling size adjustment, the user equipment selects a bundling size from the bundling size set according to the indication information sent by the network-side device for data transmission; 
     In some embodiments of the present disclosure, the user equipment may support the one-PRB bundling through the above steps. As a result, for a time division duplexing (TDD) system, especially in a case that there are a large number of antennas and the channel frequency selectivity is obvious, a frequency-selective beamforming gain may be improved. 
     Optionally, if the user equipment supports the one-PRB bundling, the bundling size set includes 1, and further includes one or more of: 2, 4, a consecutively scheduled bandwidth, and other value. 
     The consecutively scheduled bandwidth may be a consecutive bandwidth on which the user equipment is scheduled, or may be a sum of consecutive bandwidths on which the user equipment are scheduled multiple times. The 1, 2, 4, and other value may represent one PRB, two PRBs, four PRBs, and other number of PRBs respectively, and the other value may be one or more integers other than 1, 2, and 4. 
     In this implementation, the user equipment may be configured with a bundling size set including 1, such as {1, 2, 4, a consecutively scheduled bandwidth}, or other value set including 1. In this way, the network-side device may dynamically configure a bundling size of 1 for the user equipment, and the user equipment performs one-PRB bundling; or the configured bundling size is multiple PRBs, and the user equipment performs a multi-PRB bundling. Alternatively, the user equipment may select a bundling size of 1 from the bundling size set, and the user equipment performs one-PRB bundling; or the bundling size selected by the user equipment is multiple PRBs, and the user equipment performs a multi-PRB bundling. For a TDD system, especially in a case that there are a large number of antennas and the channel frequency selectivity is obvious, the one-PRB bundling may improve a frequency-selective beamforming gain. 
     Optionally, if the user equipment does not support one-PRB bundling, the bundling size set includes one or more of: 2, 4, a consecutively scheduled bandwidth, and other value except 1. 
     In this implementation, the user equipment may be configured with a bundling size set that does not include 1, such as {2, 4, a consecutively scheduled bandwidth}, or other value set that does not include 1. In this way, the network-side device may dynamically configure a bundling size of multiple PRBs for the user equipment, and the user equipment performs a multi-PRB bundling; or the user equipment may select a bundling size of multiple PRBs from the bundling size set, and the user equipment performs a multi-PRB bundling. In this way, an error caused by configuring a bundling size of 1 for the user equipment not supporting the one-PRB bundling may be avoided. 
     Optionally, the method further includes: 
     receiving, by the user equipment, DCI sent by the network-side device if the network side device turns on the function of dynamic bundling size adjustment, wherein the DCI includes a dynamic indication of the bundling size; 
     determining, by the user equipment, a bundling size to be used in data transmission according to the dynamic indication of the bundling size. 
     The DCI may dynamically indicate the bundling size through 1 bit. For example, if a value of the bundling size dynamic indication bit included in the DCI is 1, the user equipment may select a bundling size from one or two values pre-configured via a higher-layer signaling. If there are two values corresponding to the case where bit=1, a specific bundling size is determined according to an implicit correspondence, such as a scheduled bandwidth and other parameters. 
     Alternatively, if the value of the bundling size dynamic indication bit included in the DCI is 0, the user equipment may use a bundling size pre-configured via a higher-layer signaling. 
     In this implementation, the bundling size may be dynamically configured for the user equipment. 
     It should be noted that a plurality of optional implementations described in the embodiments of the present disclosure may be implemented in combination with each other or separately, which is not limited in the embodiments of the present disclosure. 
     In the embodiment, the user equipment reports capability information to a network-side device, wherein the capability information is used to indicate whether the user equipment supports one-PRB bundling, and receives a bundling size set configured by the network-side device for the user equipment according to the capability information, wherein supporting the one-PRB bundling indicates that a turn-off of a PRB bundling function is supported. Thus, the bundling size of the user equipment may be determined. 
     Referring to  FIG. 3 ,  FIG. 3  is another flowchart of a method for determining a bundling size provided in some embodiments of the present disclosure. As shown in  FIG. 3 , the method includes the following steps. 
     Step  301 , using, by the user equipment, a default bundling size or a bundling size configured via a higher-layer signaling to transmit data if the network-side device turns off a function of dynamic bundling size adjustment. 
     The turning off of the function of dynamic bundling size adjustment by the network-side device may be understood as: the network-side device turns off the function of dynamic bundling size adjustment, and notifies the user equipment. Turning off the function of dynamic bundling size adjustment may mean that the bundling size may not be adjusted dynamically. The turning off of the function of dynamic bundling size adjustment may be configured by the network-side device via a higher-level signaling, for example, the turning off of the function of dynamic bundling size adjustment is configured via a radio resource control (RRC) signaling. 
     The default bundling size may be a bundling size pre-configured by the user equipment or a bundling size predefined in a protocol. The bundling size configured via the higher-layer signaling may be a bundling size configured by the network-side device for the user equipment via a higher-layer signaling. For example, the bundling size may be a certain size in {1, 2, 4, a consecutively scheduled bandwidth}. 
     In some embodiments of the present disclosure, it may be implemented through the above steps that, if the function of dynamic bundling size adjustment is turned off, the bundling size may be obtained by default or through a higher-layer configuration, so as to prevent a situation that PRB bundling cannot be performed due to a failure in determining the bundling size when the function of dynamic bundling size adjustment is turned off. 
     Optionally, the using, by the user equipment, the default bundling size or the bundling size configured via the higher-layer signaling to transmit data includes: 
     using, by the user equipment, the default bundling size to transmit data; or 
     using, by the user equipment, the bundling size configured by the network-side device via the higher-layer signaling to transmit data, wherein the bundling size is a bundling size in a bundling size set available to the user equipment; or 
     using, by the user equipment, a minimum bundling size in a bundling size set available to the user equipment to transmit data. 
     In this implementation, if the function of dynamic bundling size adjustment is turned off, the default bundling size may be selected, or the bundling size configured by the network-side device via a higher-level signaling may be used, or a minimum bundling size in the bundling size set available to the user equipment may be used by default, so as to improve flexibility of the system. 
     In addition, the bundling size set available to the user equipment may be the bundling size set configured by the network-side device for the user equipment according to the capability information of the user equipment. For the bundling size set, refer to the bundling size set in the embodiment shown in  FIG. 2 . 
     For example, if the user equipment supports the one-PRB bundling, the network-side device may configure a bundling size from among {1, 2, 4, a consecutively scheduled bandwidth} or other value set including 1 for the user equipment via a higher-level signaling. Optionally, if the user equipment does not support the one-PRB bundling, the network-side device may configure a bundling size from among {2, 4, a consecutively scheduled bandwidth} or other value set not including 1 for the user equipment via a higher-level signaling. 
     As another example, if the user equipment supports the one-PRB bundling, the user equipment may select a minimum value from {1, 2, 4, a consecutively scheduled bandwidth} or other value set including 1 as a bundling size. Optionally, if the user equipment does not support the one-PRB bundling, the user equipment may select a minimum value from {2, 4, a consecutively scheduled bandwidth} or other value set not including 1 as a bundling size. 
     It should be understood that, the bundling size set available to the user equipment is not limited to the bundling size set obtained through reporting capability information. For example, the bundling size set available to the user equipment may be pre-configured by the user equipment, or pre-configured by the network side device for the user equipment, and so on. 
     Optionally, the method further includes: 
     receiving, by the user equipment, DCI sent by the network-side device if the network side device turns on the function of dynamic bundling size adjustment, wherein the DCI includes a dynamic indication of the bundling size; 
     determining, by the user equipment, a bundling size to be used in data transmission according to the dynamic indication of the bundling size. 
     In this implementation, the bundling size may be dynamically configured for the user equipment. 
     In the embodiment, the user equipment uses a default bundling size or a bundling size configured via a higher-layer signaling to transmit data if the network-side device turns off the function of dynamic bundling size adjustment. Thus, the bundling size of the user equipment may be determined. 
     Referring to  FIG. 4 ,  FIG. 4  is yet another flowchart of a method for determining a bundling size provided in some embodiments of the present disclosure. As shown in  FIG. 4 , the method includes the following steps. 
     Step  401 , reporting, by user equipment, capability information to a network-side device, wherein the capability information is used to indicate whether the user equipment supports one-PRB bundling, and receiving, by the user equipment, a bundling size set configured by the network-side device for the user equipment according to the capability information, wherein supporting the one-PRB bundling indicates that a turn-off of a PRB bundling function is supported; 
     Step  402 , using, by the user equipment, a default bundling size or a bundling size configured via a higher-layer signaling to transmit data if the network-side device turns off a function of dynamic bundling size adjustment. 
     For descriptions of step  401  and step  402 , reference may be made to the corresponding description of the embodiment shown in  FIG. 2 , details are not described here, and the same beneficial effects may be achieved. 
     It should be noted that, in some embodiments of the present disclosure, the execution order of step  401  and step  402  is not limited. Preferably, as shown in  FIG. 4 , step  401  is executed firstly, and then step  402  is executed. 
     Optionally, if the user equipment supports the one-PRB bundling, the bundling size set includes 1, and further includes one or more of: 2, 4, a consecutively scheduled bandwidth, and other value. 
     The consecutively scheduled bandwidth may be a consecutive bandwidth on which the user equipment is scheduled, or may be a sum of consecutive bandwidths on which the user equipment are scheduled multiple times. The 1, 2, 4, and other value may represent one PRB, two PRBs, four PRBs, and other number of PRBs respectively, and the other value may be one or more integers other than 1, 2, and 4. 
     In this implementation, the user equipment may be configured with a bundling size set including 1, so that the user equipment may perform the one-PRB bundling. For a TDD system, especially in a case that there are a large number of antennas and the channel frequency selectivity is obvious, the one-PRB bundling may improve a frequency-selective beamforming gain. 
     Optionally, if the user equipment does not support one-PRB bundling, the bundling size set includes one or more of: 2, 4, a consecutively scheduled bandwidth, and other value except 1. 
     In this implementation, the user equipment may be configured with a bundling size set that does not include 1. In this way, an error caused by configuring a bundling size of 1 for the user equipment not supporting the one-PRB bundling may be avoided. 
     Optionally, the using, by the user equipment, the default bundling size or the bundling size configured via the higher-layer signaling to transmit data includes: 
     using, by the user equipment, the default bundling size to transmit data; or 
     using, by the user equipment, the bundling size configured by the network-side device via the higher-layer signaling to transmit data, wherein the bundling size is a bundling size in a bundling size set available to the user equipment; or 
     using, by the user equipment, a minimum bundling size in a bundling size set available to the user equipment to transmit data. 
     In this implementation, if the function of dynamic bundling size adjustment is turned off, the default bundling size may be selected, or the bundling size configured by the network-side device via a higher-level signaling may be used, or a minimum bundling size in the bundling size set available to the user equipment may be used by default, so as to improve flexibility of the system. 
     In addition, the bundling size set available to the user equipment may be the bundling size set configured by the network-side device for the user equipment according to the capability information of the user equipment. For the bundling size set, refer to the bundling size set in step  401 . 
     It should be understood that, the bundling size set available to the user equipment is not limited to the bundling size set obtained through reporting capability information. For example, the bundling size set available to the user equipment may be pre-configured by the user equipment, or pre-configured by the network side device for the user equipment, and so on. 
     Optionally, the method further includes:
