Technical Field

The embodiment of the application relates to the technical field of communication, in particular to a capability reporting method and device.

Background

In a wireless communication system, uplink communication of a terminal may support multiple transmit chains, and downlink communication of the terminal may also support multiple receive chains. The transmit chain and the receive chain are both radio frequency chains. As shown in fig. 1, when the terminal transmits an uplink signal, a baseband signal is generated at a baseband, the baseband signal generates a radio frequency signal through a radio frequency transmission link, and the radio frequency signal is transmitted through an antenna, where the radio frequency link includes a radio frequency integrated circuit, a power amplifier, and a duplexer/filter. Similarly, when receiving a signal, the terminal also receives the signal through the corresponding rf receiving link. A terminal may support multiple transmit or receive chains. For example, a terminal supports one transmit chain and two receive chains. Also for example, a terminal may support two transmit chains and four receive chains. When the terminal uses two transmission links for uplink communication with the network side, a larger communication rate than one transmission link can be provided.

Currently, a terminal may access multiple network devices to support communication with the multiple network devices, in which case, the terminal may use different radio frequency links to communicate with different network devices. However, for any radio frequency link, a terminal does not always use the radio frequency link to communicate with a corresponding network device at any moment, for example, when the network device corresponding to the radio frequency link does not schedule the terminal, or when the terminal sends a signal with other network devices, the radio frequency link is idle. Therefore, when the terminal is provided with a plurality of radio frequency links to communicate with a plurality of accessed network devices, the radio frequency links are idle and resources are wasted.

One feasible implementation way is that the terminal uses the same radio frequency link to communicate with two network devices, so as to achieve the purpose of sharing the radio frequency link and improve the use efficiency of the radio frequency link. For example, in one scenario, the terminal uses the radio frequency link a to communicate with the network device a, and uses the radio frequency link b to communicate with the network device b, and when the radio frequency link a is idle, the terminal may use the radio frequency link a and the radio frequency link b to communicate with the network device b, so as to obtain a greater communication rate. In this case, the value of the antenna capability supported by the terminal is not constant, that is, the terminal may communicate with the network device using one radio frequency link or may communicate with the network device using two radio frequency links in a combined manner, and the terminal supports conversion from the value of one antenna capability to the value of another antenna capability. In order to make the scheme feasible, the terminal needs to report its own antenna capability to the network device before communicating with the network device, and how to report the antenna capability is a problem to be solved.

For convenience of understanding, some concepts and terms related to the embodiments of the present application will be described first.

1) And the radio frequency link in the uplink direction can be called a radio frequency transmitting link, and the radio frequency link in the downlink direction can be called a radio frequency receiving link. As shown in fig. 1, a baseband signal generated by the terminal at baseband generates a radio frequency signal through a radio frequency transmission link, and the radio frequency signal is transmitted through an antenna. Similarly, signals received by the terminal from the antenna are received through the rf receive chain to the baseband for processing. The radio frequency link includes a radio frequency integrated circuit, a power amplifier, and a duplexer/filter. A terminal may access a plurality of network devices, and the terminal communicates with the plurality of network devices through a plurality of radio frequency links, where one radio frequency link may correspond to one network device, for example, the terminal may access 2 or 4 network devices. Specifically, the terminal may access a plurality of network devices in a DC manner, or may access a plurality of network devices in a CA manner. The rf link may be integrated in the rf chip or may be integrated in the same chip with the baseband processing circuit.

2) DC, DC is a mode of the terminal in a Radio Resource Control (RRC) CONNECTED state (i.e., RRC _ CONNECTED state), and the network device configures a Master Cell Group (MCG) and a Secondary Cell Group (SCG) for the terminal. If the network device supports DC, the terminal in RRC _ CONNECTED state may be configured to use radio resources provided by two different network devices. For example, as shown in fig. 3a, in Long Term Evolution (LTE), a terminal is configured to use radio resources provided by two enbs, one as a Master base station (Master eNB, MeNB) and one as a Secondary base station (SeNB), which are connected by an X2 interface. One terminal in the DC is connected to one MeNB and one SeNB. As also shown in fig. 3b, in a New Radio (NR), an LTE-NR dual connectivity manner may be adopted, and the terminal is configured to use radio resources provided by an eNB in LTE and a gNB in NR, where optionally, the eNB serves as a primary base station and the gNB serves as a secondary base station. As shown in fig. 3c, it is needless to say that an NR-LTE dual-connection scheme may be adopted, in which the gbb serves as the primary base station and the eNB serves as the secondary base station. As shown in fig. 3d, it is also possible to adopt an NR-NR dual connectivity manner, where the terminal is configured to use two radio resources provided by the gNB, one serving as the primary base station and one serving as the secondary base station.

3) Antenna port, on the network side, the radio frequency link and the antenna can be abstracted as a concept of antenna port. When a terminal has N radio frequency links, the terminal supports communication with network devices using at most N antenna ports simultaneously. For example, N ═ 2, the terminal has two radio frequency links, and the terminal supports communication with the network device by using at most two antenna ports simultaneously, and in practical application, each radio frequency link corresponds to one antenna port. If the terminal uses one antenna port to communicate with the network device, the terminal may use any one of the two radio frequency links to correspond to the antenna port, or may use the two radio frequency links to simulate one antenna port at the same time, which depends on the specific implementation of the terminal side, and is transparent to the network device, and the network device only needs to schedule the terminal to transmit uplink signals on which antenna ports.

4) Antenna capabilities, the antenna capabilities including: number of antenna ports, number of layers, number of radio frequency links, number of antennas, maximum number of antenna ports, maximum number of layers, maximum number of radio frequency links, or maximum number of antennas. The number of layers refers to the number of streams of mutually uncorrelated signals contained in the transmitted data when the transmitted data is precoded. For example, a terminal uses four antenna ports to transmit data, but the same data or related data is transmitted using the four antenna ports, it can be understood that the terminal transmits a stream of data or transmits a layer of data using the four antenna ports. For another example, if the four antenna ports include port 0, port 1, port 2 and port 3, the terminal transmits the same or related stream data using port 0 and port 1, and the terminal transmits the same or related stream data using port 2 and port 3, it can be understood that the terminal transmits two layers of data. In the description of the embodiments of the present application, the description related to the antenna capability may be given by taking one expression form as an example, and the method may also be applied to other expressions of the antenna capability. In the embodiment of the present application, when "antenna capability includes", the "antenna capability indication" may be replaced with "antenna capability indication", and the meanings of the two expressions are equivalent.

In this embodiment of the application, the terminal may access two network devices in a DC or Carrier Aggregation (CA) manner, and for convenience of description, the two network devices are represented by a first network device and a second network device, and the first network device and the second network device may communicate with each other through an X2 interface. If the first network equipment and the second network equipment are network equipment in different communication system systems, the terminal establishes double connection with the first network equipment and the second network equipment in a DC connection mode; for another example, the first network device and the second network device are network devices in a system of the same communication system, and the terminal accesses the first network device and the second network device in a CA manner. Regardless of the manner of accessing the two network devices, one of the two network devices is a primary base station, and the other network device is a secondary base station. Before executing the communication method provided by the embodiment of the present application, the terminal needs to establish a connection with the first network device or the second network device, and establishing the connection may refer to establishing an RRC connection. If the terminal establishes connection with the first network device, the first network device is a primary base station, the second network device is a secondary base station, the terminal can directly send a signal to the first network device, if the terminal needs to send a signal to the second network device, the terminal needs to send the signal to the first network device first, and the first network device transmits the signal to the second network device, where the signal may be an RRC signaling. Similarly, if the terminal establishes a connection with the second network device, the second network device is a primary base station, the first network device is a secondary base station, the terminal may directly send a signal to the second network device, if the terminal needs to send a signal to the first network device, the terminal needs to send the signal to the second network device first, and the second network device transmits the signal to the first network device, where the signal may be an RRC signaling.

In the embodiment of the application, a radio frequency link through which a terminal communicates with a first network device and a radio frequency link through which the terminal communicates with a second network device are different, it is assumed that the terminal uses the first radio frequency link when sending a signal to the first network device, and uses the second radio frequency link when sending a signal to the second network device, and when the terminal does not send a signal to the second network device, the second radio frequency link is an idle radio frequency link, and the terminal can jointly use the first radio frequency link and the idle second radio frequency link to send a signal to the first network device, so that the power of sending a signal to the first network device can be improved, the sharing of the radio frequency links is realized, the utilization rate of the radio frequency links is improved, and the uplink transmission rate is improved. Of course, the number of the first radio frequency links may be one or more. Likewise, the number of the second radio frequency links may be one or more. The radio frequency link is an expression form of the antenna capacity of the terminal, and based on the application background, the value of the antenna capacity when the terminal sends a signal to the first network device includes two values, one value corresponds to the number of the first radio frequency links used by the terminal, and the other value corresponds to the total number of the first radio frequency links used by the terminal and the idle second radio frequency links used by the terminal. The value of the antenna capability when the terminal sends a signal to the first network device is not a fixed value, but is different in the antenna capability under different application scenarios (or different use conditions), or has different antenna capabilities under different application scenarios (or different use conditions), and the terminal needs to report the antenna capability to the first network device before sending a signal to the network device (the first network device) by using the antenna capability. The embodiment of the application mainly introduces how the terminal reports the antenna capability to the network device, or how the network device obtains the antenna capability of the terminal. In the following description, the usage condition may also be considered as an application scenario, which is a time for the terminal to switch using different antenna capability values. The use condition can be configured arbitrarily, and the embodiment of the application is not limited. In a first application scenario, the terminal sends a signal to the network device by using the antenna capability of the first value, and in a second application scenario, the terminal sends a signal to the network device by using the antenna capability of the second value. For example, the usage condition may refer to whether the terminal is configured with a Time Division Multiplexing (TDM) pattern. Then, when the terminal is not configured with the time division multiplexing mode, the terminal uses the antenna capability of the first value to send signals to the network device, and when the terminal is configured with the time division multiplexing mode, the terminal uses the antenna capability of the second value to send signals to the network device.

Based on the above description and the communication system architecture shown in fig. 2, as shown in fig. 4, a method for reporting the capability provided by the embodiment of the present application is described in detail below.

S401, the terminal reports the antenna capability of the terminal to the network equipment, and the network equipment receives the antenna capability of the terminal reported by the terminal.

Wherein the antenna capabilities include: number of antenna ports, number of layers, number of radio frequency links, number of antennas, maximum number of antenna ports, maximum number of layers, maximum number of radio frequency links, or maximum number of antennas. In the description of the embodiments of the present application, the description related to the antenna capability may be given by taking one expression form as an example, and the method may also be applied to other expressions of the antenna capability.

For convenience of description, the network device that reports the antenna capability of the terminal is referred to as a first network device.

As described above, when the first network device is the primary base station, the reporting, by the terminal, the antenna capability of the terminal to the first network device is as follows: the terminal directly reports the antenna capability of the terminal to the first network equipment, and the first network equipment directly receives the antenna capability reported by the terminal. When the second network device is the master base station, the reporting, by the terminal, the antenna capability of the terminal to the first network device means that: and the terminal reports the antenna capability of the terminal to the first network equipment through the second network equipment. The first network device receiving the antenna capability of the terminal reported by the terminal means: and the first network equipment receives the antenna capability of the terminal reported by the terminal through the second network equipment. Specifically, the terminal reports the antenna capability of the terminal to the second network device, and after the second network device receives the antenna capability of the terminal, the antenna capability of the terminal is transmitted to the first network device through the X2 interface.

S402, the terminal sends signals to the network equipment by using the antenna capacity, and the network equipment receives the signals sent by the terminal.

The signal may be a Physical Uplink Shared Channel (PUSCH) or a Sounding Reference Signal (SRS).

Optionally, before the terminal uses the antenna capability to send the signal to the network device, the network device may further indicate, to the terminal, a value of the antenna capability used when sending the signal. Specifically, the network device sends first downlink control information to the terminal, the terminal receives the first downlink control information sent by the network device, the first downlink control information is used for scheduling or instructing the terminal to send the PUSCH, and is used for instructing the terminal to send a value of an antenna capability used when the PUSCH is sent, after receiving the first downlink control information sent by the network device, the terminal sends the PUSCH to the network device by using the antenna capability of the first value according to the first downlink control information, or sends the PUSCH to the network device by using the antenna capability of the second value according to the first downlink control information.

If the signal is the SRS, before the terminal uses the antenna capability to send the SRS to the network device, the network device may also indicate to the terminal a value of the antenna capability used when sending the SRS. Specifically, the network device sends second downlink control information to the terminal, the terminal receives the second downlink control information sent by the network device, the second downlink control information is used for triggering the terminal to send the SRS, and is used for indicating the value of the antenna capability used when the terminal sends the SRS, the terminal sends the SRS to the network device by using the antenna capability of the first value according to the second downlink control information, or the terminal sends the SRS to the network device by using the antenna capability of the second value according to the second downlink control information.

In a possible implementation manner, the network device sends indication information to the terminal, receives indication information from the network device, where the indication information is used to indicate that the terminal enables the antenna capability, and the terminal enables the antenna capability according to the indication information.

The following details how the terminal reports the antenna capability of the terminal to the network device, or how the network device obtains the antenna capability of the terminal.

The terminal reports parameters to the network device, where the parameters include the terminal's own capabilities, such as antenna capability and radio frequency capability, and also include characteristics of the terminal when sending signals. Specifically, as shown in fig. 5, the parameter structure reported by the terminal to the network device includes several layers. The maximum boxes represent parameter groups of frequency band combinations, the middle-sized boxes represent parameter groups of frequency bands, the minimum boxes represent parameter groups of carriers, a parameter structure reported by the terminal may include one or more frequency band combinations, a frequency band combination may include one or more frequency bands, a frequency band may include one or more carriers, a frequency band combination may be indicated by the parameter groups represented by the one or more maximum boxes, a frequency band may be indicated by the parameter groups represented by the one or more middle-sized boxes, and a carrier may be indicated by the parameter groups represented by the one or more minimum boxes. The parameter set represented by the maximum box describes the characteristics of band combination (band combination), different band combinations are distinguished by the identifiers of the band combinations, one band combination is represented by one identifier, and the parameter set represented by the maximum box describes the characteristics of all bands and all carriers in the band combination. The parameter group represented by the middle-sized box describes the characteristics of each frequency band contained in the frequency band combination, each frequency band can be represented by a frequency band identifier, and the parameter group represented by the middle-sized box is characterized by all carriers in the frequency band. For example, the parameter structure shown in fig. 5 includes a frequency band combination, where the frequency band combination includes two frequency bands, and one frequency band includes two carriers. The parameters represented by the minimum box are used for describing the characteristics of each carrier in the frequency band, different carriers are distinguished by identifiers of the carriers, one carrier is represented by one identifier, and the parameters in the carriers are used for describing the characteristics of the terminal in the carrier.

Based on the parameter structure, in the embodiment of the application, the terminal reports the antenna capability of the terminal to the network device, and the reporting can be performed from different levels.

Firstly, each band combination band per CC is combined for each frequency band, and the terminal reports the antenna capability of the terminal to the network device.

In this reporting structure, the terminal places the parameter describing the antenna capability in the parameter describing the characteristics of the carrier, so as to indicate that the antenna capability of the terminal is applicable to the carrier.

The terminal may report the antenna capability of the terminal to the network device in any reporting manner, and it is within the scope claimed in the embodiment of the present application as long as it reports each carrier of each frequency band combination for each frequency band.

Several possible reporting methods are exemplified below.

Method 1, a terminal sends two Information Elements (IEs) to a network device, and the two information elements are represented by a first IE and a second IE, where the first IE is used to indicate the antenna capability of the terminal, and the second IE is used to indicate the usage condition of the antenna capability of the terminal. Or, the first message carries an IE, where the IE is used to indicate the antenna capability of the terminal, and the first message further includes an additional description, which describes the use condition of the antenna capability of the terminal, and the additional description may be described in a text manner.

For example, assuming that the antenna capability of the terminal is expressed in Layers (Layers), the parameter describing the antenna capability (i.e., the first IE) is max Number MIMO-Layers CB-PUSCH, where CB means that the antenna capability is based on codebook uplink transmission, and the value of the parameter describing the antenna capability is 2, i.e., two Layers. The second IE describes a usage condition of the antenna capability, the type of the second IE may be a boolean type, and a value of the boolean type is yes or no, for example, the second IE may be two layers CB-By Opportunity, where a value of the second IE two layers CB-By Opportunity is (tube), which indicates that a value of the number of layers when the terminal sends a signal to the network device is not fixed to two layers but opportunistic, that is, the number of layers when the terminal sends a signal to the network device may be one layer in one application scenario, and may be two layers in another application scenario. The second IE may also be an enumeration type, for example, the second IE may be represented as max Number MIMO-Layers Condition estimated { non, by Opportunity }, where the value ENUMERATED by the second IE is non (non) or opportunistic (by Opportunity), and the value ENUMERATED by the second IE is by the second IE in the ENUMERATED values, which indicates that the value of the Number of Layers when the terminal sends a signal to the network device is not fixed to two Layers, but opportunistic two Layers.

Similarly, for Non-codebook uplink transmission, the first IE may be max Number MIMO-layer no CB-PUSCH, where no CB refers to that the antenna capability is based on Non-codebook uplink transmission, and a parameter of the antenna capability takes a value of 2, that is, two Layers. The use condition (i.e. the second IE) describing the antenna capability is two layers Non CB-By Opportunity, where the type of the second IE may be a boolean type, and a value of the boolean type is yes or no, and a value of the second IE two layers Non CB-By Opportunity is yes (tune), which indicates that a value of the number of layers when the terminal sends a signal to the network device is not fixed to two layers, but opportunistically two layers, that is, the number of layers when the terminal sends a signal to the network device may be one layer in one application scenario, and may be two layers in another application scenario. The second IE may also be an enumeration type, for example, the second IE may be represented as max Number MIMO-Layers Condition estimated { non, by Opportunity }, where the value ENUMERATED by the second IE is non (non) or opportunistic (by Opportunity), and the value ENUMERATED by the second IE is by the second IE in the ENUMERATED values, which indicates that the value of the Number of Layers when the terminal sends a signal to the network device is not fixed to two Layers, but opportunistic two Layers.

The possible expression forms of the reported parameter structure are as follows:

or, possible expression forms of the reported parameter structure are as follows:

method 2, the terminal sends a third IE to the network device, wherein the third IE is used for indicating the antenna capability of the terminal and the use condition of the antenna capability of the terminal.

Wherein the type of the third IE may be an enumerated type. For example, the third IE is represented in the form of: an antenna capability-enumeration type { capability 1, capability 2, … … capability n }, where capability 1-capability n are n enumerated antenna capabilities or values of n enumerated antenna capabilities, and one of the capabilities is an antenna capability when a terminal sends a signal to a network device.

For example, if the antenna capability is expressed in the form of layer numbers (layers), it is assumed that the value of the antenna capability when the terminal sends a signal to the network device is changed from one layer to two layers. For the uplink transmission based on the codebook, the expression form of the third IE may be max Number MIMO-Layers CB-PUSCH estimated { One Layers, two Layers, One Plus One Layers }, where estimated indicates that the type of the third IE is an ENUMERATED type, and the value of the third IE is One Plus One Layer in the ENUMERATED values; similarly, based on the Non-codebook uplink transmission, the expression form of the third IE may be max Number MIMO-Layer Non CB-PUSCH estimated { One Layer, two Layers, One Plus One Layer }, and the value of the third IE is One Plus One Layer in the ENUMERATED values. The value of the antenna capability is (1+1) layers, namely One Plus One layers, which indicates that the number of layers when the terminal sends signals to the network equipment is One layers in One application scenario and two layers in another application scenario.

The possible expression forms of the reported parameter structure are as follows:

and 3, the terminal sends two IEs to the network equipment, wherein the two IEs are marked as a fourth IE and a fifth IE, the fourth IE is used for indicating that the value of the antenna capability of the terminal is the first value, and the fifth IE is used for indicating that the value of the antenna capability of the terminal is the second value. The network device may determine, according to the received values of the two antenna capabilities, that the value of the antenna capability of the terminal may be converted from one value to another value, for example, the antenna capability of the terminal is a first value in one application scenario and a second value in another application scenario.

Wherein the type of the fourth IE may be an enumerated type. For example, the fourth IE is represented by: an antenna capability-enumeration type { capability 1, capability 2, … … capability n }, where capability 1-capability n are n enumerated antenna capabilities or values of n enumerated antenna capabilities, and one of the capabilities is a first value of the antenna capability when the terminal sends a signal to the network device. Likewise, the type of the fifth IE may be an enumerated type, for example, the fifth IE is represented in the form: an antenna capability-enumeration type { capability 1, capability 2, … … capability n }, where capability 1-capability n are values of n enumerated antenna capabilities or n enumerated antenna capabilities, and one of the capabilities is a second value of the antenna capability when the terminal sends a signal to the network device. Of course the type of the fourth and fifth IEs may be other types.

Similarly, for example, if the antenna capability is expressed in the form of layer numbers (layers), it is assumed that the value of the antenna capability when the terminal sends a signal to the network device is changed from one layer to two layers. Then: for the uplink transmission based on the codebook, the expression form of the fourth IE may be max Number MIMO-Layers CB-PUSCH estimated { one layer, two Layers, four Layers }, and the value of the fourth IE is one layer in ENUMERATED values; the fifth IE may be expressed in the form of max Number MIMO-Layers CB-PUSCH-By opportunity estimated { one Layers, two Layers, four Layers }, and the value of the fifth IE is two of enumerated values. For non-codebook based uplink transmission, the expression form of the fourth IE may be max Number MIMO-Layers nobb-PUSCH estimated { one layer, two Layers, four Layers }, and the value of the fourth IE is one layer in ENUMERATED values; the fifth IE may be represented in the form of max Number MIMO-layer nobb-PUSCH-By opportunity estimated { one Layers, two Layers, four Layers }, and the value of the fifth IE is two Layers of enumerated values. Optionally, the fourth IE may further indicate a use condition when the value of the antenna capability of the terminal is the first value, for example, the fourth IE may further indicate that the value of the antenna capability is the first value when the terminal is not configured with the time division multiplexing mode. The fifth IE may further indicate a used antenna when the value of the antenna capability of the terminal is the second value, for example, the fifth IE may further indicate that the value of the antenna capability is the second value when the terminal is configured with the time division multiplexing mode. The first parameter group and the second parameter group are used to indicate the characteristics of the terminal for the same carrier, and the other parameters except for the fourth IE and the fifth IE in the first parameter group and the second parameter group may be the same.

The possible expression forms of the reported parameter structure are as follows:

wherein the desirable value range of MIMO-LayersUL may also be

MIMO-LayersUL::＝ENUMERATED{oneLayer,twoLayers,fourLayers,onePlusOneLayer}。

In addition, if there are multiple carriers in a frequency band of a frequency band combination, the characteristics of a carrier may be indicated by one or more parameter sets, and then the fourth IE and the fifth IE may be carried in one parameter set or may be carried in two parameter sets. Based on this, for one carrier, that is, the same carrier of the same frequency band combination, the terminal may report a parameter set, where the parameter set includes the first value and the second value, and may further include an applicable condition. The terminal may report a first parameter group and a second parameter group, where the first parameter group includes a parameter indicating that the value of the antenna capability of the terminal is a first value, and the second parameter group includes a parameter indicating that the value of the antenna capability of the terminal is a second value.

For example, the first parameter set is denoted by FeatureSetUplinkID ═ 0, corresponding to CC0, and configuring maxnumberbelmimo-LayersCB-PUSCH with a value of two layers; the second parameter set is represented by FeatureSetUplinkID ═ 1, corresponding to CC1, and configures maxnumberbelmimo-LayersCB-PUSCH with a value of one layer.

It should be noted that, in the above methods 1, 2, and 3, the number of layers is used as an expression form of the antenna capability, and when the expression form of the antenna capability is other forms, the reporting method may be adopted as well; the value of the antenna capability is illustrated by taking an example of changing from 1 to 2, and when the value of the antenna capability is changed from 2 to 4, the antenna capability and the use condition can be represented by the method, and only the numerical value in the method needs to be changed.

And secondly, combining each frequency band (per band combination) for each frequency band, and reporting the antenna capability of the terminal to the network equipment by the terminal.

In the reporting structure, the terminal places the parameter describing the antenna capability in the parameter describing the characteristics of the frequency band, so as to indicate that the antenna capability of the terminal can be applied to the frequency band. When the network equipment receives the antenna capability reported by the terminal, the network equipment determines that the terminal can use the antenna capability on the frequency band.

The terminal may report the antenna capability of the terminal to the network device in any reporting manner, and as long as reporting is performed for each frequency band combination, the terminal belongs to the scope claimed in the embodiment of the present application.

For several exemplary reporting methods, reference may be made to the method 1, the method 2, and the method 3, that is, for each frequency band combination, the terminal reports the antenna capability to the network device by any one of the methods described in the methods 1 to 3.

For some descriptions of the method 3, if there are multiple frequency bands in a frequency band combination, and the characteristics of each frequency band can be indicated by one or more parameter sets, then the fourth IE and the fifth IE may be carried in one parameter set or two parameter sets. Based on this, for a frequency band, that is, the same frequency band of the same frequency band combination, the terminal may report a parameter set, where the parameter set includes the first value and the second value, and may further include an applicable condition. The terminal may report a third parameter group and a fourth parameter group, where the third parameter group includes a parameter for indicating that the value of the antenna capability of the terminal is the first value, and the fourth parameter group includes a parameter for indicating that the value of the antenna capability of the terminal is the second value. The third parameter group and the fourth parameter group are used to indicate the characteristics of the terminal for the same frequency band, and the other parameters except the fourth IE and the fifth IE in the third parameter group and the fourth parameter group may be the same.

For example, for the expression form of the antenna capability as the Number of Layers, the name of the reported parameter may be the same as that in the above methods 1 to 3, that is, max Number MIMO-Layers CB-PUSCH, or a new parameter name may be introduced to represent a parameter for combining each frequency band for each frequency band, for example, a parameter maxnumberber MIMO-Layers band. Of course, the IE or the name of the parameter is not limited in the embodiments of the present application. Except that the names of the IEs may be the same or different, the remaining methods for expressing the antenna capability may refer to the descriptions of methods 1 to 3, which are not described herein again.

For example, on the parameter of each frequency band combined with each frequency band, the possible expression form of the reported parameter structure is as follows:

or the following steps:

or the following steps:

and thirdly, for each band combination (band combination), the terminal reports the antenna capability of the terminal to the network equipment.

In the reporting structure, the terminal places the parameter describing the antenna capability in the parameter describing the characteristic of the frequency band combination, so as to indicate that the antenna capability of the terminal can be applied to the frequency band combination.

The terminal may report the antenna capability of the terminal to the network device in any reporting manner, and as long as the terminal reports the antenna capability to each frequency band combination, the terminal belongs to the scope claimed in the embodiment of the present application.

For several exemplary reporting methods, reference may be made to the method 1, the method 2, and the method 3, that is, the terminal reports the antenna capability to the network device by any one of the methods described in the methods 1 to 3, on the parameter of each frequency band combination.

As some explanations for the method 3, if there are multiple frequency band combinations and the characteristics of each frequency band combination can be indicated by one or more parameter sets, the fourth IE and the fifth IE may be carried in one parameter set or two parameter sets. Based on this, for a frequency band combination, that is, the same frequency band combination, the terminal may report a parameter set, where the parameter set includes the first value and the second value, and may further include an applicable condition. The terminal may report a fifth parameter group and a sixth parameter group, where the fifth parameter group includes a parameter for indicating that the value of the antenna capability of the terminal is the first value, and the sixth parameter group includes a parameter for indicating that the value of the antenna capability of the terminal is the second value. The fifth parameter group and the sixth parameter group are used to indicate the characteristics of the terminal for the same frequency band combination, and the parameters in the fifth parameter group and the sixth parameter group except for the fourth IE and the fifth IE may be the same.

For example, for the expression form of the antenna capability as the Number of Layers, the name of the reported parameter may be the same as that in the above methods 1 to 3, that is, max Number MIMO-Layers CB-PUSCH, or a new parameter name may be introduced to represent a parameter for combining each frequency band for each frequency band, for example, the parameter max Number MIMO-Layers band Combination. Of course, the IE or the name of the parameter is not limited in the embodiments of the present application. Except that the names of the IEs may be the same or different, the remaining methods for expressing the antenna capability may refer to the descriptions of methods 1 to 3, which are not described herein again.

For example, on the parameter of each frequency band combination, the possible expression form of the reported parameter structure is as follows:

or the following steps:

or the following steps:

and for the network equipment side, the network equipment receives the antenna capacity and the use condition reported by the terminal. Specifically, with reference to the above-described reporting methods, the network device receives a first IE and a second IE reported by the terminal, where the first IE is used to indicate an antenna capability of the terminal for each frequency band in each frequency band combination, and the second IE is used to indicate a use condition of the antenna capability of the terminal for each frequency band in each frequency band combination in each carrier; or the first IE is used for indicating the antenna capability of the terminal for combining each frequency band of each frequency band, and the second IE is used for indicating the use condition of the terminal for combining the antenna capability of each frequency band; or the first IE is used for indicating the antenna capability of the terminal for each frequency band combination, and the second IE is used for indicating the use condition of the terminal for the antenna capability of each frequency band combination. Or the network device receives a third IE reported by the terminal, where the third IE is used to indicate the antenna capability of the terminal for each frequency band combined with each carrier of each frequency band, and is used to indicate the use condition of the antenna capability of the terminal for each frequency band combined with each carrier of each frequency band; or the third IE is used for indicating the antenna capability of the terminal for combining each frequency band for each frequency band and indicating the use condition of the antenna capability of the terminal for combining each frequency band for each frequency band; or, the third IE is used to indicate the antenna capability of the terminal for each band combination, and is used to indicate the use condition of the antenna capability of the terminal for each band combination. Or the network device receives a fourth IE and a fifth IE reported by the terminal, where the fourth IE is used to indicate that the value of the antenna capability of the terminal for each carrier of each frequency band combination is a first value, and the fifth IE is used to indicate that the value of the antenna capability of the terminal for each carrier of each frequency band combination is a second value; or, the fourth IE is used to indicate that the terminal has a first value for the antenna capability of each frequency band combination, and the fifth IE is used to indicate that the terminal has a second value for the antenna capability of each frequency band combination; or, the fourth IE is configured to indicate that the terminal takes the value of the antenna capability of each frequency band combination as the first value, and the fifth IE is configured to indicate that the terminal takes the value of the antenna capability of each frequency band combination as the second value. Of course, the fourth IE is used to indicate a use condition when the value of the antenna capability of the terminal is the first value; and the fifth IE is used for indicating the use condition when the value of the antenna capability of the terminal is the second value. Or, the network device receives a first parameter group and a second parameter group reported by the terminal, wherein the first parameter group includes: a parameter for indicating the terminal to take the antenna capability of each frequency band combined with each carrier wave of each frequency band as a first value, wherein the second parameter group comprises: a parameter for indicating the antenna capability of the terminal for combining each carrier wave of each frequency band to each frequency band, the parameter being a second value; or, the network device receives a third parameter group and a fourth parameter group reported by the terminal, where the third parameter group includes: a parameter for indicating that the terminal takes the value of the antenna capability of each frequency band combined by each frequency band as a first value, wherein the fourth parameter group comprises: a parameter for indicating the terminal to take the value of the antenna capability of each frequency band combined with each frequency band as a second value; or, the network device receives a fifth parameter group and a sixth parameter group reported by the terminal, where the fifth parameter group includes: a parameter for indicating that the value of the antenna capability of each frequency band combination by the terminal is the first value, wherein the sixth parameter group comprises: and the parameter is used for indicating that the value of the antenna capability of each frequency band combination of the terminal is the second value.

In the method for reporting the antenna capability, the values of the antenna capability reported to the network device by the terminal include two values. Taking the antenna capability when the terminal sends a signal to the first network device as the maximum layer number as an example, two values are 1 and 2, namely, a single layer and a double layer. If the means of the prior art is adopted, the antenna capacity reported by the terminal to the network equipment is a single layer, the terminal always supports at most the single layer to send uplink signals, and the antenna capacity reported by the terminal to the network equipment is a double layer, the terminal always supports at most the double layer to send uplink signals. In the method provided by the embodiment of the application, when the terminal sends a signal to the first network device, the value of the antenna capacity is changed between a single layer and a double layer, if the terminal adopts a reporting mode in the prior art, and when the reporting antenna capacity is the single layer, the network device cannot schedule the terminal to send the double layer, that is, the beneficial effect of using the idle radio frequency link, which is required to be achieved by the embodiment of the application, cannot be realized, if the terminal adopts the reporting mode in the prior art, and when the reporting antenna capacity is the double layer, the network device cannot distinguish whether the terminal can always use the double layer to send the signal or can opportunistically send the signal using the double port. Actually, the switching of the antenna capability value of the terminal refers to switching of a time-frequency link, and whether the terminal can perform radio-frequency link switching depends on the implementation of internal hardware of the terminal. The terminal may have different capabilities in different ranges based on different hardware architecture designs. The use range refers to the switching of the antenna capability, which can be performed on frequency band combination, frequency band or carrier. For example, the radio frequency link 1 of the terminal may be switched to the frequency band 1 and the frequency band 2, and the radio frequency link 2 of the terminal may be switched to the frequency band 2 and the frequency band 3. When the radio frequency link 2 works in the frequency band 2, the terminal can report values capable of supporting different antenna capabilities for the frequency band 2, wherein the first value is a single layer and corresponds to transmission of only the radio frequency link 2; the second value is a double layer, and when the corresponding radio frequency link 1 is also switched to the frequency band 2, the two radio frequency links of the radio frequency link 1 and the radio frequency link 2 are transmitted together. However, when the radio frequency link 2 operates in the frequency band 3, the terminal has only a single-layer transmission capability, and under the condition that the terminal has only a single-layer transmission capability, the antenna capabilities of the terminal on each carrier are the same, so that the capability reported by the terminal is reported for each frequency band combination, and compared with the capability reported for each carrier, the capability reported by the terminal is helpful for reducing signaling overhead. Similarly, when the rf link can only be switched to some carriers in some frequency bands, the capability reporting is only reasonable for the carriers. Therefore, by using the method provided by the embodiment of the present application, the terminal can report two values of antenna capabilities and an application scenario of the two values of antenna capabilities to the network device, and report the antenna capabilities by using a parameter structure for a frequency band combination, a frequency band or different levels of a carrier, so that the use range of the antenna capabilities can be further refined, different hardware implementation situations can be respectively handled, and when the switchable range of the hardware implementation capabilities is relatively large, the capability reporting range is also relatively large for the purpose of reducing signaling overhead. On the contrary, when the switchable range corresponding to the hardware implementation capability is smaller, the capability can be reported only for the smaller range, so that the method for reporting the antenna capability with different values becomes feasible.
