To facilitate a better understanding of the embodiments of the present application, a description of related art will be first provided.

In wireless communications, modulation is the primary method of accomplishing signal spectrum shifting. For example, as shown in fig. 2, the mixer may perform nonlinear operation on the low-frequency input signal F1 and the modulated carrier wave F0 to generate a sum frequency signal or a difference frequency signal of the two signals, and select a desired high-order frequency output signal F2 therefrom, that is, complete frequency spectrum shifting from low frequency to high frequency, where the frequency relationship is f2=f1+f0.

For wideband signals, its center frequency point is referred to as the dc carrier position, also referred to as the DC (Direct Current) position, as shown by F1 and F2 in fig. 3.

In a specific implementation, the modulation of the signal is implemented in a radio frequency chip (RFIC) of the terminal device, as shown in fig. 4, a baseband chip (BBIC) of the terminal device inputs a baseband signal to the RFIC, further, in the RFIC, the input low-frequency baseband signal and a local oscillator signal (LO, frequency is F0) of the RFIC are mixed to generate a radio frequency signal, and after being amplified by a Power Amplifier (PA), the radio frequency signal is finally transmitted through an antenna of the terminal device.

In the orthogonal frequency division multiplexing (Orthogonal frequency-division multiplexing, OFDM) modulation scheme, the DC position will usually have strong signal interference, and the receiving end needs to remove this carrier to improve the receiving signal-to-noise ratio, so the receiving end needs to know the accurate DC position. The DC location is typically signaled to the receiving end by the transmitting end. In the above behavior example, the terminal device needs to inform the network device of the exact DC position of the transmitted signal, so that the network device can accurately remove the subcarrier of the DC position.

In the NR system, in order to save power of a terminal, a BWP concept is introduced, and a network device generally configures a smaller transmission and reception bandwidth for the terminal device, thereby reducing the complexity of transmitting and receiving signals by the terminal device. For example, there may be multiple channels in the entire frequency band, and after the terminal device accesses one channel, the network device may further configure not more than 4 BWP (only one BWP may be activated at the same time), and the terminal device may operate in this activated BWP in subsequent communications. The terminal device may report DC positions based on the configured BWP, and if 4 BWP are configured on a single carrier, the terminal device reports 4 DC positions to the network device at most.

In some scenarios, the terminal device may operate on multiple carriers, each carrier may be configured with multiple BWP, each two BWP may determine a DC position, so that the potential DC positions are very numerous, as shown in fig. 5, carrier 1 is configured with BWP 1-BWP 4, carrier 2 is configured with BWPx-BWPz, … …, carrier n is configured with BWPa-BWPd, the potential BWP combinations are 4*3 × … ×4, and in case that the number of configured carriers is large, how to report the DC positions is an urgent problem to be solved.

Fig. 6 is a schematic interaction diagram of a method for reporting a dc carrier location according to an embodiment of the present application, as shown in fig. 6, the method 200 may include at least some of the following steps:

s202, the terminal equipment determines at least one direct current carrier position according to first information;

and S203, the terminal equipment reports the at least one direct current carrier position to the network equipment.

In the embodiment of the present application, the direct current carrier position or DC position may be replaced with each other.

Optionally, in some embodiments, the first information includes at least one of:

BWP configuration corresponding to a first carrier and a second carrier in a first carrier set of the terminal equipment respectively, wherein the first carrier is the carrier with the lowest frequency in the first carrier set, and the second carrier is the carrier with the highest frequency in the first carrier set;

and the request information of the network equipment is used for requesting the terminal equipment to report the direct current carrier positions aiming at a specific plurality of carriers and/or a specific plurality of BWPs.

It should be understood that the content of the first information is merely an example, and in other embodiments, the first information may also include other reference information that affects DC position determination, for example, the number of transmission links corresponding to the carriers configured on the terminal device, whether the uplink transmission and the downlink reception of the terminal device share the DC position, etc., which is not limited in this application.

Optionally, in some embodiments of the present application, the method 200 further includes:

s201, the terminal equipment receives the request information sent by the network equipment.

Alternatively, the request information of the network device may be sent to the terminal device through existing signaling, for example, may be carried in configuration information such as frequency band configuration, carrier configuration, BWP configuration, and the like, and sent to the terminal device. Or may also be sent to the terminal device through a new signaling, which is not limited in this application.

It should be understood that the embodiments of the present application do not specifically limit the specific configuration manner of the carrier configuration and BWP configuration on the terminal device. For example, carrier configuration and BWP configuration may be configured through a radio resource control (Radio Resource Control, RRC) message. The activated carrier configuration may be configured by downlink control information (Downlink Control Information, DCI), and the activated BWP configuration may also be configured by DCI.

Optionally, in the embodiment of the present application, the determining, by the terminal device, the DC position according to the BWP configuration corresponding to the carrier with the lowest frequency band and the highest frequency band in the first carrier set may be determined by the terminal device, or may be based on an indication of the network device, or may be predefined (or default).

After the terminal device determines the at least one DC position, further, in subsequent signal transmission, the DC position of the transmission signal may be set at the at least one DC position, and the at least one DC position is reported to the network device, so that the network device accurately eliminates the sub-carrier of the DC position based on the at least one DC position.

In the embodiment of the application, the terminal device may operate on multiple carriers simultaneously, for example, the terminal device is configured to employ carrier aggregation (Carrier Aggregation, CA) (for example, may include in-band continuous CA and in-band discontinuous CA) or dual connectivity operation mode.

In the embodiment of the present application, the terminal device may use a single transmission link to support simultaneous operation on the multiple carriers, or may use multiple transmission links to support simultaneous operation on the multiple carriers. In other words, the terminal device may use a single transmission link architecture, or may also use a multiple transmission link architecture, or the multiple carriers correspond to a single transmission link, or to multiple transmission links.

In embodiments of the present application, a transmit chain may be used to implement modulation and power amplification of a carrier signal, and the transmit chain may include a Power Amplifier (PA) and a mixer. In some cases, the transmit chain architecture may refer to employing a PA architecture.

When a single transmission link is adopted, the terminal device can determine the DC position required to be reported corresponding to the single transmission link, and when a plurality of transmission links are adopted, the terminal device can determine the DC position required to be reported corresponding to each transmission link in the plurality of transmission links.

Alternatively, in some embodiments, the terminal device may inform the network device whether it employs a single transmit link or multiple transmit links. The network device may be notified, for example, by existing signaling (e.g., an uplink RRC message), or by newly added signaling, or may be reported to the network device in the same message as the DC location bearer, which is not limited in this application.

Alternatively, the determination manners of the DC positions to be reported corresponding to different transmission links may be the same or may be different, which is not limited in the present application.

Alternatively, DC positions to be reported corresponding to different transmission links may be reported by the same message, or may also be reported by different messages, which is not limited in this application.

Hereinafter, a manner of determining the DC position will be described with reference to specific embodiments, but the present application is not limited thereto.

Mode 1

In this mode 1, the first carrier set includes a plurality of carriers configured by the network device.

Alternatively, the plurality of carriers may refer to uplink carriers configured by the network device.

Alternatively, the first carrier set may include all carriers configured by the network device to the terminal device. For example, the network device configures the terminal device with M carriers, and the first carrier set may include the M carriers.

In this mode 1, the terminal device may determine the DC position according to BWP configurations respectively corresponding to the lowest frequency carrier and the highest frequency carrier among the plurality of carriers configured by the network device.

In this mode 1, the first carrier is a carrier with a lowest frequency among a plurality of carriers configured by the network device, and the second carrier is a carrier with a highest frequency among the plurality of carriers configured by the network device.

As an example, the terminal device may determine the DC position from all BWP configurations on the first carrier and all BWP configurations on the second carrier. For example, if there are n BWP configurations on the first carrier and m BWP configurations on the second carrier, n×m DC positions can be determined.

As another example, the terminal device may determine the DC location from a particular BWP configuration on the first carrier and a particular BWP configuration on the second carrier.

Alternatively, the specific BWP configuration on the first carrier may refer to an activated BWP configuration or a BWP configuration with the lowest frequency point, and the specific BWP configuration on the second carrier may refer to an activated BWP configuration or a BWP configuration with the highest frequency point.

Next, in the example of fig. 5, carrier 1 is the carrier with the lowest configured carrier intermediate frequency point, carrier n is the carrier with the highest configured carrier intermediate frequency point, and in this embodiment of the present application, the terminal device may determine DC positions according to all BWP configurations on carrier 1 and carrier n, and may determine 4*4 DC positions, that is, the network device only needs to report 16 DC positions, which reduces signaling overhead.

Mode 2

In this mode 2, the first carrier set includes a plurality of carriers configured and activated by the network device.

Alternatively, the plurality of carriers may refer to uplink carriers configured and activated by the network device.

For example, the network device configures the terminal device with M carriers, and further, the network device activates N carriers in the M carriers, where N is smaller than M, the first carrier set may include the N carriers.

In this mode 2, the terminal device may determine the DC position according to the BWP configuration corresponding to the lowest frequency and the highest frequency, respectively, of the plurality of carriers configured and activated by the network device.

In this mode 2, the first carrier is the lowest frequency carrier among the plurality of carriers configured and activated by the network device, and the second carrier is the highest frequency carrier among the plurality of carriers configured and activated by the network device.

As an example, the terminal device may determine the DC position from all BWP configurations on the first carrier and all BWP configurations on the second carrier.

As illustrated in fig. 7, the carriers configured on the terminal device are carrier 1 to carrier 5.

In one case, the activated carriers include carrier 1, carrier 2 and carrier 4, where carrier 1 is the carrier with the lowest frequency point in the configured and activated carrier, and carrier 4 is the carrier with the highest frequency point in the configured and activated carrier, the terminal device may determine the DC position according to all BWP configurations on carrier 1 and carrier 4.

In another case, the activated carriers include carrier 1, carrier 3 and carrier 4, where carrier 1 is the carrier with the lowest frequency point of the configured and activated carrier, and carrier 4 is the carrier with the highest frequency point of the configured and activated carrier, then the terminal device may also determine the DC position according to all BWP configurations on carrier 1 and carrier 4.

Optionally, in some embodiments of the present application, the plurality of carriers configured by the network device correspond to a single transmission link, or are implemented using a single transmission link.

Alternatively, in other embodiments, the plurality of carriers configured by the network device may correspond to a plurality of transmission links, in which case the terminal device may determine the DC position required to be reported by each transmission link according to the carrier configuration corresponding to each transmission link or the activated carrier configuration.

As an example, the plurality of transmission links includes a first transmission link that supports a first set of carriers, which may include carriers configured by the network device corresponding to the first transmission link, or which include carriers configured by the network device and activated corresponding to the first transmission link. Further, the terminal device may determine the DC position to be reported for the first transmission link in a similar manner as in mode 1 or mode 2.

As an example, the plurality of transmission links further includes a second transmission link supporting a second set of carriers, wherein the second set of carriers includes carriers configured by the network device corresponding to the second transmission link or the second set of carriers includes carriers configured by the network device and activated corresponding to the second transmission link. Further, the terminal device may determine the DC-position to be reported for the second transmission link in a similar manner as in mode 1 or mode 2.

As illustrated in connection with fig. 8 and 9, in the example of fig. 8, where the terminal device is configured with carriers 1 to 4, where the 4 carriers correspond to a single transmission link, when determining the DC position in mode 1, the DC position may be determined according to the BWP configuration corresponding to carrier 1 and carrier 4. In the example of fig. 9, the terminal device is configured with carriers 1 to 4, where carrier 1 and carrier 2 correspond to the transmission link 1, carrier 3 and carrier 4 correspond to the transmission link 2, and when determining the DC position in mode 1, the DC position corresponding to the transmission link 1 may be determined according to the BWP configuration corresponding to carrier 1 and carrier 2, and the DC position corresponding to the transmission link 2 may be determined according to the BWP configuration corresponding to carrier 3 and carrier 4.

Alternatively, in the foregoing implementation, the uplink transmission and the downlink reception of the terminal device do not share a DC position, i.e. the uplink transmission and the downlink reception of the terminal device use independent DC positions. The independent DC positions are adopted for uplink and downlink, so that the influence of downlink CA on the uplink DC position is avoided.

Mode 3

In this mode 3, the first carrier set includes an uplink carrier and a downlink carrier configured by the network device.

As a specific example, the first carrier set may include all uplink carriers configured by the network device to the terminal device and all downlink carriers. For example, the network device configures the terminal device with M uplink carriers and K downlink carriers, and the first carrier set may include the M uplink carriers and the K downlink carriers, where M and K are positive integers greater than 1.

Alternatively, in this mode 3, the terminal device transmits and receives the common DC position in the uplink and downlink, in which case the influence of the downlink carrier needs to be considered in determining the uplink DC position.

In this mode 3, the first carrier is the carrier with the lowest frequency among the uplink carrier and the downlink carrier configured by the network device, and the second carrier is the carrier with the highest frequency among the uplink carrier and the downlink carrier configured by the network device.

Mode 4

In this mode 4, the first carrier set includes an uplink carrier and a downlink carrier configured and activated by the network device.

For example, if the network device configures M uplink carriers and K downlink carriers for the terminal device, and further, the network device activates N uplink carriers of the M uplink carriers and activates P downlink carriers of the K downlink carriers, the first carrier set may include the N uplink carriers and the P downlink carriers.

In this mode 4, the terminal device may determine the DC position according to the BWP configuration corresponding to the lowest frequency and the highest frequency carrier among the uplink carrier and the downlink carrier configured and activated by the network device.

In this mode 4, the first carrier is the lowest frequency carrier among the uplink and downlink carriers configured and activated by the network device, and the second carrier is the highest frequency carrier among the uplink and downlink carriers configured and activated by the network device.

As another example, the terminal device may determine the DC location from an active BWP configuration on the first carrier and an active BWP configuration on the second BWP.

Therefore, based on the method for determining the DC position in the embodiment of the present application, the DC position reported by the terminal device is decoupled from a specific carrier position in multiple carriers configured by the network device, and is only related to the carrier with the lowest frequency point and the highest frequency point, which is beneficial to reducing the number of determined DC positions, thereby reducing signaling overhead.

Mode 5

In this mode 5, the terminal device may determine the DC position according to the request information of the network device.

Optionally, in some embodiments, the terminal device determines, when receiving the request information of the network device, a DC position according to the request information of the network device, and determines, when not receiving the request information of the network device, the DC position according to the manner in the foregoing embodiments.

Alternatively, in some embodiments, the request information may be sent before the network device activates BWP, or may be sent after BWP is activated.

Alternatively, in some embodiments, the reporting of the DC location by the terminal device may be before the network device activates BWP or after the network device activates BWP.

Optionally, in some embodiments, the request information of the network device includes identification information of a carrier and/or BWP, such as a carrier number and/or BWP ID, for which the network device requests the terminal device to report the dc carrier location. The terminal device may determine the DC location according to a specific carrier or BWP based on the request of the network device, and further report the DC location.

For example, if the request information of the network device includes index numbers of carrier 1 and carrier 2, the terminal device may determine the DC position according to BWP configurations corresponding to carrier 1 and carrier 2, respectively. The specific determination mode refers to the implementation mode.

As another example, the request information of the network device includes BWP1, BWP2, BWP x, BWP ID of BWPa, and the terminal device may determine the DC position based on the four BWP.

In this manner 5, the terminal device determines the DC position based on the carrier configuration or BWP configuration requested by the network device, and performs reporting of the DC position, instead of determining the DC position based on all the carrier configurations, so that signaling overhead can be reduced.

In summary, when determining the DC position, the terminal device only considers the BWP configuration corresponding to the carrier with the lowest frequency point and the highest frequency point, which is favorable for reducing signaling overhead, and further, considers factors such as the transmitting link architecture of the terminal device and whether the uplink transmission and the downlink reception share the DC position, and adaptively adjusts the determining mode of the DC position, so that the reported DC position is more accurate and effective, and thus, the network device can effectively eliminate interference based on the reported DC position.
