Description
Technical Field
The embodiment of the application relates to the technical field of communication, in particular to a method and a device for reporting radio frequency parameters.
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 two antenna capabilities of the terminal to the network device before communicating with the network device. Under different antenna capabilities, some radio frequency parameters related to the antenna capabilities of the terminal are different, and how to report the related radio frequency parameters under different antenna capabilities 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) The antenna capability, which is one of the capabilities of the terminal, is indicated by an antenna capability parameter. The antenna capability parameter includes any one of: 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 antenna capability may be indicated by taking an example of one or several antenna capability parameters, and the method may also be applied to other antenna capability parameters. In the embodiment of the present application, the first antenna capability and the second antenna capability have different antenna capability parameters. Alternatively, the first antenna capability and the second antenna capability are two different values of antenna capability.
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. Based on the above application context, the antenna capability when the terminal sends a signal to the first network device may include a first antenna capability and a second antenna capability, where the first antenna capability corresponds to the number of the terminals using the first radio frequency link, and the second antenna capability corresponds to the total number of the terminals using the first radio frequency link and the idle second radio frequency link. In different application scenarios (or different use conditions), the terminal uses different antenna capabilities to transmit signals to the first network device. The usage condition can also be considered as an application scenario, and is a switching occasion when the terminal uses different antenna capabilities. The use condition can be configured arbitrarily, and the embodiment of the application is not limited. For example, in a first application scenario, the terminal uses the first antenna capability to transmit signals to the network device, and in a second application scenario, the terminal uses the second antenna capability to transmit signals to the network device. 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 transmits a signal to the network device using the first antenna capability, and when the terminal is configured with the time division multiplexing mode, the terminal transmits a signal to the network device using the second antenna capability.
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. In practical application, the time and process for reporting the parameters by the terminal may be any one of the following times and processes, but are not limited to this. The terminal may report when accessing the network and performing attach (attach). Or after receiving an inquiry (acquire) message from the network side, the terminal reports the parameters. Specifically, the terminal wants to update the capability, sends a request to the core network, the Mobility Management Entity (MME) sends an instruction to the network device, the network device sends an inquiry message to the terminal, and the terminal reports the parameters after receiving the inquiry message. Or the terminal reports the parameters after executing handover. This paragraph description applies to all method embodiments provided herein.
When the terminal transmits signals to the first network device using different antenna capabilities, there are some associated radio frequency capabilities that are different. The parameter for indicating the radio frequency capability is a radio frequency parameter, and in the embodiment of the present application, how the terminal reports the radio frequency parameter to the first network device is described in an important way, or how the first network device obtains the radio frequency parameter of the terminal is described in an important way. In the following description, the first network device may be briefly described as a 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 radio frequency parameters provided in the embodiment of the present application is described in detail below.
S401, the terminal reports the first radio frequency parameter and the second radio frequency parameter to the network equipment, and the network equipment receives the first radio frequency parameter and the second radio frequency parameter reported by the terminal.
The first radio frequency parameter is used for indicating the radio frequency capability of the terminal when the terminal uses the first antenna capability to send signals to the network equipment, and the second radio frequency parameter is used for indicating the radio frequency capability of the terminal when the terminal uses the second antenna capability to send signals to the network equipment.
After receiving the first radio frequency parameter and the second radio frequency parameter reported by the terminal, the network device configures a parameter for communication to the terminal, wherein the configured parameter for communication is determined according to the first radio frequency parameter and the second radio frequency parameter reported by the terminal. For example, the first radio frequency parameter reported by the terminal indicates that the terminal supports 4 SRS at maximum, the network device may only configure 2 SRS for the terminal, and indicate that the terminal supports 2 SRS at maximum when the terminal uses the first antenna capability to transmit a signal.
S402, the terminal sends signals to the network equipment by using the first antenna capability or the second antenna capability, 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).
Specifically, the radio frequency capability in this embodiment may be one or more of the following types: uplink beam management, the maximum number of Sounding Reference Signals (SRS) supported, SRS transmit antenna switching, or the maximum number of SRS simultaneously transmitted on each carrier.
In the embodiment of the application, the terminal reports a first radio frequency parameter and a second radio frequency parameter when the antenna capability of the terminal is a first antenna capability and a second antenna capability, the first radio frequency parameter corresponds to the radio frequency capability of the first antenna capability of the terminal, and the second radio frequency parameter corresponds to the radio frequency capability of the second antenna capability of the terminal.
The terminal may report the radio frequency parameter by using two Information Elements (IEs), and specifically, the terminal may report the first radio frequency parameter to the network device by using the first IE and report the second radio frequency parameter to the network device by using the second IE.
For example, the radio frequency capability is uplink beam management (uplink beam management).
The uplink beam management configures a maximum number of resource sets (resource sets) of the SRS for beam management (beam management), and a maximum number of resources (resource) in each resource set. When the antenna capability of the terminal for sending a signal to the network device is the first antenna capability and the second antenna capability, the number of SRS resource groups for beam management and the number of resources in each group supported by the terminal may be different.
The terminal indicates, using the first radio frequency parameter: when a terminal uses a first antenna capability to send signals to network equipment, the terminal supports a first SRS resource group number used for beam management and a first maximum resource number in each group; the terminal indicates, using the second radio frequency parameter: when the terminal uses the second antenna capability to transmit signals to the network device, the terminal supports a second number of SRS resource groups for beam management and a second maximum number of resources in each group.
For example, the value of the first antenna capability is 1, the value of the second antenna capability is 2, and when the terminal supports the first antenna capability, the maximum number of resources supported by the terminal in each resource group is 16 at most; when the terminal indicates the second antenna capability, the maximum number of resources supported by the terminal in each resource group is at most 8, wherein the number of resources may be a periodic, aperiodic or semi-persistent SRS number.
The terminal indicates, using the first radio frequency parameter: when the terminal uses the first antenna capacity to send signals to the network equipment, the radio frequency capacity of the terminal is that the maximum number of resources in each resource group is 16 at most; the terminal indicates, using the second radio frequency parameter: and when the terminal uses the second antenna capability to send signals to the network equipment, the radio frequency capability of the terminal is that the maximum number of resources in each resource group is supported to be at most 8.
In a possible implementation manner, the first IE may be an original IE used for characterizing uplink beam management, for example, the first IE is uplink beam management and is used for carrying the first radio frequency parameter. The second IE is a newly added IE, which may be denoted as uplink beam management byopportunity, and is used to carry the second radio frequency parameter.
One possible representation of the reported parameter structure is as follows:
second, the radio frequency capability is the maximum number of supported SRSs (upported SRS-Resources).
The maximum number of supported SRSs is used to indicate the maximum number of various types of SRSs supported in various ranges of the terminal. When the antenna capabilities of the terminal for transmitting signals to the network device are different, the maximum number of SRSs supported by the terminal may be different.
The terminal indicates, using the first radio frequency parameter: when the terminal uses the first antenna capability to send signals to the network equipment, the maximum number of the supported SRSs is the first number; the terminal indicates, using the first radio frequency parameter: when the terminal uses the first antenna capability to send signals to the network equipment, the maximum number of the supported SRSs is the second number.
For example, the first antenna capability has a value of 1 and the second antenna capability has a value of 2. The aperiodic SRS resources supported on each BWP may be 8 when the terminal supports the first antenna capability and 4 when the terminal supports the second antenna capability.
The terminal indicates, using the first radio frequency parameter: when the terminal uses the first antenna capability to send signals to the network equipment, the maximum number of the supported aperiodic SRS is 8; the terminal indicates, using the second radio frequency parameter: when the terminal uses the second antenna capability to transmit signals to the network device, the maximum number of supported aperiodic SRS is 4.
In a possible implementation manner, the first IE may be an original IE used for characterizing the maximum number of supported SRSs, for example, the first IE may be denoted as upportedSRS-Resources, and is used for carrying the first radio frequency parameter. The second IE is a newly added IE, which may be denoted as supported srs-resource by opportunity, and is used to carry the second radio frequency parameter.
One possible representation of the reported parameter structure is as follows:
supportedSRS-Resources SRS-Resources OPTIONAL,
supportedSRS-ResourcesByOpportunity SRS-Resources OPTIONAL,
it should be noted here that the value types of the first IE supported SRS-Resources and the second IE supported SRS-Resources by opportunity, are SRS-Resources, and the SRS-Resources also have a parameter maxnumberber SRS-Ports-resource. The representation of the parameter maxNumberbERSS-Ports-PerResource in the reported parameter structure can be as follows:
maxNumberber SRS-Ports-Perresource ENUMERATED { n1, n2, n4 }. In the embodiment of the application, the value of maxnumberber srs-Ports-PerResource in supported srs-Resources is n1, and the value of maxnumberber srs-Ports-PerResource in supported srs-Resources by opportunity is n 2.
In the third example, the radio frequency capability is SRS transmit antenna switching (supported SRS-TxPortswitch).
supported SRS-txport switch indicates what SRS transmit antenna switching is supported by the UE. When the antenna capability of the terminal for sending signals to the network device is the first antenna capability and the second antenna capability, the SRS transmitting antenna switching supported by the terminal may be different.
The terminal indicates, using the first radio frequency parameter: when the terminal uses the first antenna capability to send signals to the network equipment, the terminal supports switching of the first type of SRS transmitting antenna; the terminal indicates, using the second radio frequency parameter: and when the terminal uses the second antenna capability to send signals to the network equipment, the terminal supports the switching of the second type of SRS transmitting antenna.
For example, the first antenna capability has a value of 1 and the second antenna capability has a value of 2. When the terminal supports the first antenna capability, t1r4 is supported, i.e. one radio frequency link is rotated over four physical antenna terminals. When the terminal supports the second antenna capability, t2r4 is supported, i.e. two radio frequency links are rotated on four physical antenna terminals.
The terminal indicates, using the first radio frequency parameter: when the terminal uses the first antenna capacity to send signals to the network equipment, a radio frequency link is supported to transmit on four physical antenna terminals in a rotating mode; the terminal indicates, using the second radio frequency parameter: and when the terminal uses the second antenna capability to send signals to the network equipment, the terminal supports the two radio frequency links to transmit on the four physical antenna terminals in turn.
In one possible implementation, the first IE may be an original IE characterizing supported SRS transmit antenna switching types. For example, the first IE may be denoted as IE srs-TxSwitch for carrying the first radio frequency parameters. The second IE is a newly added IE, which may be represented as srs-TxSwitchByOpportunity, and is used to carry the second rf parameter.
One possible representation of the reported parameter structure is as follows:
srs-TxSwitch SRS-TxSwitch OPTIONAL,
srs-TxSwitchByOpportunity SRS-TxSwitch OPTIONAL
example four, the radio frequency capability is the maximum number of SRSs transmitted simultaneously on each carrier (maxnumber simultaneoussrs-PerCC).
The maximum number of the SRSs simultaneously transmitted on each carrier is used to indicate the number of the SRSs that the terminal can simultaneously transmit on the same symbol (symbol) in each carrier (CC).
The terminal indicates, using the first radio frequency parameter: when the terminal uses the first antenna capability to send signals to the network equipment, the number of the SRS which can be simultaneously sent on the same symbol on each carrier wave supported by the terminal is a first number; the terminal indicates, using the second radio frequency parameter: when the terminal uses the second antenna capability to send signals to the network device, the number of the SRSs that can be simultaneously sent on the same symbol on each supported carrier is the second number.
For example, the first antenna capability has a value of 1 and the second antenna capability has a value of 2. When the terminal supports the first antenna capability, the terminal supports that 4 SRS can be simultaneously sent on the same symbol on each carrier; when the terminal supports the second antenna capability, it is supported that 2 SRSs can be simultaneously transmitted on the same symbol on each carrier.
The terminal indicates, using the first radio frequency parameter: when the terminal uses the first antenna capability to send signals to the network equipment, the terminal supports that 4 SRS can be sent on the same symbol on each carrier wave at the same time; the terminal indicates, using the second radio frequency parameter: when the terminal uses the second antenna capability to send signals to the network device, it is supported that 2 SRSs can be sent simultaneously on the same symbol on each carrier.
In one possible implementation, the first IE is denoted by maxnumber simultaneoussrs-PerCC, and is configured to carry the first radio frequency parameter. The second IE is denoted by maxNumber Simultaneous SRS-PerCCByOpport, and is used for carrying second radio frequency parameters.
One possible representation of the reported parameter structure is as follows:
maxNumberSimultaneousSRS-PerCC INTEGER(1..4)OPTIONAL,
maxNumberSimultaneousSRS-PerCCByOpportunity INTEGER(1..4)OPTIONAL。
in a possible implementation manner, a method for reporting the radio frequency parameter by the terminal or a method for determining the radio frequency parameter of the terminal by the network device is as follows.
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 frequency band combinations (bandcombination), different frequency band combinations are distinguished by the identification of the frequency band combinations, one frequency band combination is represented by one identification, and the parameter set represented by the maximum box describes the characteristics of all frequency bands and all carriers in the frequency 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 present application, the terminal reports the radio frequency parameters (including the first radio frequency parameter and the second radio frequency parameter) of the terminal to the network device, and the reporting can be performed from different levels.
For example, each frequency band combination carrier (per band combination per band CC) is combined for each frequency band, and the terminal reports the radio frequency parameters of the terminal to the network device. And when the network equipment receives the radio frequency parameters reported by the terminal, determining the radio frequency capability of the terminal on the carrier.
For another example, each band combination (band combination) is performed for each band, and the terminal reports the radio frequency parameters of the terminal to the network device. In the reporting structure, the terminal places the radio frequency parameters into the parameters for describing the characteristics of the frequency band, so as to indicate that the radio frequency capability of the terminal can be applied to the frequency band. And when the network equipment receives the radio frequency parameters reported by the terminal, determining the radio frequency capability of the terminal on the frequency band.
For another example, for each band combination (per band combination), the terminal reports the radio frequency parameters of the terminal to the network device, and in this reporting structure, the terminal places the radio frequency parameters in parameters for describing the characteristics of the band combination, so as to indicate that the radio frequency capability of the terminal can be applied to this band combination. And when the network equipment receives the radio frequency parameters reported by the terminal, determining the radio frequency capability of the terminal on the frequency band combination.
By the method for reporting the radio frequency parameters, the radio frequency parameters corresponding to the terminal under different antenna capabilities can be reported to the network equipment, so that the scheme that the terminal can use an idle radio frequency link is feasible, the use efficiency of the radio frequency link can be improved, and the uplink transmission rate can be improved.
Based on the above description and the communication system architecture shown in fig. 2, as shown in fig. 6, another method for reporting radio frequency parameters is further provided in the embodiments of the present application. The details are as follows.
S601, the terminal reports the first antenna capacity, the second antenna capacity and the radio frequency parameter of the terminal to the network equipment, and the network equipment receives the first antenna capacity, the second antenna capacity and the radio frequency parameter reported by the terminal.
The radio frequency parameter is a parameter for indicating radio frequency capability of the terminal. The radio frequency capability includes at least one of: the method comprises the steps of supporting PUSCH transmission coherence of a physical uplink shared channel, and supporting codebook subsets or uplink dual-port phase tracking reference signals. The radio frequency capability is only significant when the antenna capability of the terminal is the second antenna capability, and the radio frequency capability is not significant when the antenna capability of the terminal is the first antenna capability. For example, the antenna capability parameter is the number of antenna ports, the first antenna capability is one port (i.e., the number of antenna ports is 1), the second antenna capability is two ports (i.e., the number of antenna ports is 2), and when the radio frequency capability is a supported codebook subset (codebook subset) or a supported physical uplink shared channel PUSCH transmission coherence (PUSCH-transmission), the radio frequency capability is used to characterize a relationship between two antennas, and all the radio frequency capabilities are meaningless for the first antenna capability. In this case, the terminal only needs to report one radio frequency parameter, and the network device can determine that the radio frequency parameter is used for indicating the radio frequency capability of the terminal under the second antenna capability.
After receiving the first antenna capability, the second antenna capability and the radio frequency parameter reported by the terminal, the network device configures a parameter for communication to the terminal, wherein the configured parameter for communication is determined according to the radio frequency parameter reported by the terminal. For example, the radio frequency parameter reported by the terminal indicates that the terminal supports 4 SRS at maximum, and the network device may only be configured with 2 SRS for the terminal.
S602, the terminal sends a signal to the network equipment by using the first antenna capability or the second antenna capability, and the network equipment receives the signal sent by the terminal.
The signal may be a PUSCH signal or an SRS signal.
The following examples are given.
For example, the radio frequency capability is supported codebook subset (codebook subset) or supported PUSCH transmission coherence (PUSCH-transmission), and both of the radio frequency capabilities can be used to indicate which precoding matrix can be used when the terminal employs precoding of the basic codebook. The expression form of the radio frequency parameter may be pusch-transmission coherence, and if the value of the first antenna capability is 1 and the value of the second antenna capability is 2, when the terminal uses the first antenna capability to send a signal, it means that the terminal does not need to perform precoding, then the radio frequency parameter pusch-transmission coherence is a meaningless parameter, and the terminal does not need to report the parameter for the first antenna capability. The radio frequency parameter pusch-nscoherence is a meaningful parameter when the terminal transmits using the second antenna capability. The terminal and the network device default the radio frequency parameter to be a radio frequency capability for indicating when the terminal uses the second antenna capability to transmit signals.
For another example, the rf capability is an uplink dual-port phase tracking reference signal used to indicate whether a dual-port ULPTRS can be supported. Specifically, the upstream dual-port phase tracking reference signal is represented by a radio frequency parameter, twoportptrs, that occupies two bits, the first bit indicating whether the terminal supports the downstream dual-port phase tracking reference signal (twoportptrs _ DL), and the second bit indicating whether the terminal supports the upstream dual-port phase tracking reference signal (twoportptrs _ UL). If the value of the first antenna capability is 1 and the value of the second antenna capability is 2, when the terminal uses the first antenna capability to transmit signals, it is impossible to support uplink dual-port PTRS, and then the second bit of the radio frequency parameter twoportptrs is meaningless for the first antenna capability. The second bit of the radio frequency parameter twoportptrs only makes sense when the terminal is transmitting using the second antenna capability. The terminal and the network device default to the radio frequency parameter twoportptrs for indicating the radio frequency capability when the terminal transmits signals using the second antenna capability.
In a possible implementation manner, the method for reporting the radio frequency parameter by the terminal or the method for determining the radio frequency parameter by the network device may also be the method described in the above embodiment, and details are not described here again.
By the method for reporting the radio frequency parameters, the radio frequency parameters corresponding to the terminal under different antenna capabilities can be reported to the network equipment, so that the scheme that the terminal can use an idle radio frequency link is feasible, the use efficiency of the radio frequency link can be improved, and the uplink transmission rate can be improved.
