[0003] The related art introduces txDirectCurrentLocation reporting for terminal devices.

The embodiments described below with reference to the drawings are illustrative and are for the purpose of explaining the present application, but are not intended to limit the present application.

[0051] In order to better understand the information reporting method disclosed in the embodiment of the present application, the following first describes a communication system to which the embodiment of the present application is applied.

[0052] Referring to FIG. 1, FIG. 1 is a schematic diagram of the architecture of a communication system provided by an embodiment of the present application. The communication system includes, but is not limited to, one first network device, one second network device, and one terminal device. The number and form of devices shown in FIG. 1 are exemplary and do not limit the embodiment of the present application. In practical applications, the system may include two or more network devices and two or more terminal devices. Take as an example that the communication system shown in FIG. 1 includes one network device 101 and one terminal device 102.

[0053] It should be noted that the technical solutions of the embodiments of the present application may be applied to various communication systems, such as a long term evolution (LTE) system, a 5th generation (5G) mobile communication system, a 5G new radio (NR) system, or other future new mobile communication systems.

[0054] The network device 101 in the embodiment of the present application is a network side entity for transmitting and receiving signals. For example, the network device 101 may be an evolved base station (eNB), a transmission reception point (TRP), a next generation base station (gNB) in an NR system, a base station in other future mobile communication systems, or an access node in a wireless fidelity (WiFi) system. The embodiment of the present application does not limit the specific technology and the specific device form used by the network device. The network device provided by the embodiment of the present application is composed of a central unit (CU) and a distributed unit (DU), where the CU may be called a control unit, and the protocol layer of the network device, for example, a base station, can be separated using the CU-DU structure, and some protocol layer functions are centrally controlled by the CU, and the remaining or all protocol layer functions are distributed to the DU, and the CU centrally controls the DU.

[0055] The terminal device 102 in the embodiment of the present application is a user-side entity for transmitting and receiving signals, for example, a mobile phone. The terminal device may be called a terminal device (terminal), a user device (user equipment, UE), a mobile station (MS), a mobile terminal device (MT), etc. The terminal device may be an automobile with a communication function, a smart car, a mobile phone, a wearable device, a tablet (Pad), a computer with a wireless transceiver function, a virtual reality (VR) terminal device, an augmented reality (AR) terminal device, a wireless terminal device in industrial control, a wireless terminal device in self-driving, a wireless terminal device in remote medical surgery, a wireless terminal device in a smart grid, a wireless terminal device in transportation safety, a wireless terminal device in a smart city, a wireless terminal device in a smart home, etc. The embodiment of the present application does not limit the specific technology and the specific device used by the terminal device.

[0056] In mobile communication technology, when a terminal device or a network device transmits a signal, the inherent phase noise will cause a large noise in the carrier frequency, which is usually called carrier leakage, and will cause signal distortion in the subcarrier where the local oscillator (LO) is located, which is usually called DC subcarrier (DC, Direct Current). In the uplink, the network device needs to know the position of the DC subcarrier of the terminal device, so that it can carry out compensation processing according to the position of the DC subcarrier to improve the demodulation performance of the base station.

[0057] In the LTE (Long Term Evolution) system, in order to avoid the influence of carrier leakage on the DC subcarrier, the terminal device needs to offset the DC subcarrier by 7.5KHz in the baseband, which reduces the influence of carrier leakage on the DC subcarrier. In addition, the bandwidth of the terminal device and the system bandwidth of the network device are consistent, so the DC subcarrier position of the terminal is known and unique to the network device.

[0058] In the 5G (5th Generation Mobile Communication Technology) system, BWP (bandwidth part) is introduced, that is, multiple BWPs can be configured on one single carrier, so the bandwidth of the terminal device does not need to match the system bandwidth of the network device. Therefore, the position of the DC carrier is unknown to the base station, and with the introduction of BWP, the DC subcarrier of each UE has a difference, so that the terminal device does not need to offset the DC subcarrier by 7.5KHz in the baseband to simplify the receiver demodulation complexity. However, in order to improve the demodulation performance of the network device, the network device still needs to know the DC subcarrier position of the terminal.

[0059] In the related art, txDirectCurrentLocation reporting is introduced for terminal devices, which transmit the location of DC subcarriers in each carrier to network devices. However, this reporting method is only applicable when the number of single carriers or local oscillators is equal to the number of component carriers (CCs), and the signaling overhead is large.

[0060] The communication system described in the embodiment of the present application is intended to more clearly explain the technical matters of the embodiment of the present application, and does not limit the technical matters provided in the embodiment of the present application. It will be understood by those skilled in the art that with the evolution of system architecture and the emergence of new business scenes, the technical matters provided in the embodiment of the present application can be similarly applied to similar technical problems.

[0061] Hereinafter, the information reporting method and device provided by the present application will be described in detail with reference to the accompanying drawings.

[0062] Please refer to Fig. 2, which is a schematic flowchart of an information reporting method provided by an embodiment of the present application. It should be noted that the information reporting method of the embodiment of the present application is executed by a terminal device. As shown in Fig. 2, the method can include the following steps:

[0063] In step 201, send DC subcarrier information to a network device, where the DC subcarrier information includes the number of local oscillators of the terminal device and component carrier information and / or bandwidth portion information corresponding to each local oscillator of the at least one local oscillator.

[0064] Here, the component carrier information and / or the bandwidth portion information corresponding to each local oscillator of the at least one local oscillator is for determining an actual position of the at least one DC subcarrier of the terminal device.

[0065] In an embodiment of the present application, the terminal device transmits DC subcarrier information to the network device, and the network device can determine an actual position of at least one DC subcarrier of the terminal device based on the received DC subcarrier information.

[0066] In the embodiment of the present application, the DC subcarrier information includes the number of local oscillators of the terminal device, and the terminal device has at least one local oscillator, and as mentioned above, the subcarrier where the local oscillator is located will cause signal distortion, so each local oscillator corresponds to one DC subcarrier.

[0067] In an embodiment of the present application, the DC subcarrier information further includes component carrier information and / or bandwidth portion information corresponding to each local oscillator of the at least one local oscillator, for determining an actual position of at least one DC subcarrier of the terminal device. One local oscillator may correspond to at least one component carrier, for example, one local oscillator LO1 corresponds to component carrier CC1 and component carrier CC2, and another local oscillator LO2 corresponds to component carrier CC3.

[0072] Furthermore, the bandwidth portion information corresponding to each local oscillator among the at least one local oscillator included in the DC subcarrier information may be activated bandwidth portion information, for example, the activated bandwidth portion in the component carrier CC1 is BWP11, the activated bandwidth portion in the component carrier CC2 is BWP22, and the activated bandwidth portion in the component carrier CC3 is BWP31, and the local oscillator LO1 included in the DC subcarrier information corresponds to the bandwidth portions BWP11 and BWP22, and the local oscillator LO2 corresponds to the bandwidth portion BWP31.

[0073] As a third possible embodiment, the DC subcarrier information includes component carrier information and bandwidth portion information corresponding to each local oscillator of the at least one local oscillator.

[0074] Optionally, the component carrier and the bandwidth portion can be coded, and the local oscillator LO corresponding to the component carrier number and the bandwidth portion number in a mapping manner can be included in the DC subcarrier information and sent to the network device. For example, the local oscillator LO1 corresponds to the component carrier CC1 and the component carrier CC2 and the bandwidth portions BWP11, BWP12, BWP13, BWP14, BWP21, BWP22, BWP23 and BWP24, and the local oscillator LO2 corresponds to the component carrier CC3 and the bandwidth portions BWP31, BWP32, BWP33 and BWP34.

[0075] Furthermore, the bandwidth portion information corresponding to each local oscillator among the at least one local oscillator included in the DC subcarrier information may be activated bandwidth portion information, for example, the activated bandwidth portion in the component carrier CC1 is BWP11, the activated bandwidth portion in the component carrier CC2 is BWP22, and the activated bandwidth portion in the component carrier CC3 is BWP31, and the local oscillator LO1 included in the DC subcarrier information corresponds to the component carrier CC1 and the component carrier CC2 and the bandwidth portions BWP11 and BWP22, and the local oscillator LO2 corresponds to the component carrier CC3 and the bandwidth portion BWP31.

[0076] In an embodiment of the present application, the network device can determine the actual location of the DC subcarrier based on the component carrier information and / or bandwidth portion information corresponding to each received local oscillator.

[0077] In some embodiments, the terminal device sends default position information of the DC subcarriers corresponding to each local oscillator of the at least one local oscillator to the network device, and the default position information may be included in the DC subcarrier information and is used to indicate the default position of the DC subcarriers corresponding to each local oscillator, where each DC subcarrier corresponding to each local oscillator has corresponding default position information, that is, two local oscillators correspond to the default position information of two DC subcarriers.

[0078] Optionally, the default position of the DC subcarrier corresponding to any of the local oscillators is: a geometric center between a left edge of a first component carrier and a right edge of a second component carrier among at least one component carrier corresponding to a local oscillator, where the first component carrier is the leftmost component carrier among the at least one component carrier corresponding to the local oscillator in the frequency domain, and the second component carrier is the rightmost component carrier among the at least one component carrier corresponding to the local oscillator in the frequency domain; a geometric center between a left edge of a first activated component carrier and a right edge of a second activated component carrier among at least one activated component carrier corresponding to a local oscillator, where the first activated component carrier is the leftmost activated component carrier in the frequency domain among the at least one activated component carrier corresponding to the local oscillator, and the second activated component carrier is the rightmost activated component carrier in the frequency domain among the at least one activated component carrier corresponding to the local oscillator; The geometric center may be one of a left edge of a first activated bandwidth portion and a right edge of a second activated bandwidth portion of at least one activated bandwidth portion corresponding to a local oscillator, where the first activated bandwidth portion is the leftmost activated bandwidth portion of the at least one activated bandwidth portion corresponding to the local oscillator in the frequency domain, and the second bandwidth portion is the rightmost activated bandwidth portion of the at least one activated bandwidth portion corresponding to the local oscillator in the frequency domain.

[0080] In some embodiments, in response to there being an offset between the actual position and the default position of the DC subcarrier, the terminal device further transmits offset information of the actual position relative to the default position to the network device, and the offset information may be included in the DC subcarrier information.

[0081] In some embodiments, the number of local oscillators in the terminal device may be included in dual power amplifier architecture (dualPA-Architecture) signaling or other predefined signaling and transmitted to the network device.

[0082] It should be noted that the information reporting method provided by the embodiment of the present application can be applied not only to multi-carrier aggregation but also to other communication systems, such as dual connectivity (DC) systems.

[0083] To sum up, send DC subcarrier information to a network device, where the DC subcarrier information includes the number of local oscillators of the terminal device and component carrier information and / or bandwidth portion information corresponding to each local oscillator of the at least one local oscillator, where the component carrier information and / or bandwidth portion information corresponding to each local oscillator of the at least one local oscillator is for determining an actual position of at least one DC subcarrier of the terminal device, so that the network device can determine the actual position of the DC subcarrier in the terminal device based on the information reported by the terminal device, which can effectively improve the demodulation performance of the network device, improve communication efficiency, reduce signaling overhead, and improve the universality of the method.

It should be noted that the information reporting method of the embodiment of the present application is executed by a terminal device. As shown in Fig. 3, the method can include the following steps:

[0085] In step 301, send DC subcarrier information to a network device, where the DC subcarrier information includes the number of local oscillators of the terminal device, component carrier information and / or bandwidth portion information corresponding to each local oscillator among the at least one local oscillator, and default position information of the DC subcarrier corresponding to each local oscillator among the at least one local oscillator.

[0086] Here, the default position information of the DC subcarrier corresponding to the local oscillator is used to indicate the default position of the DC subcarrier.

[0087] As a first possible implementation form, the default position of a DC subcarrier corresponding to a local oscillator is the geometric center between a left edge of a first component carrier and a right edge of a second component carrier among at least one component carrier corresponding to the local oscillator.

[0088] Here, the first component carrier is the leftmost component carrier in the frequency domain among at least one component carrier corresponding to the local oscillator, and the second component carrier is the rightmost component carrier in the frequency domain among at least one component carrier corresponding to the local oscillator.

[0089] For example, refer to Fig. 4, which is a schematic diagram of a default position of a DC subcarrier provided by an embodiment of the present application, in which the local oscillator LO corresponds to three component carriers CC1, CC2 and CC3. The default position of the DC subcarrier corresponding to the local oscillator is the geometric center between the left edge of a first component carrier and the right edge of a second component carrier among at least one component carrier corresponding to the local oscillator, that is, the geometric center between the left edge of CC1 and the right edge of CC3, as shown in Fig. 4.

[0090] It is further noted that if the local oscillator corresponds to only one component carrier, the default position of the DC subcarrier corresponding to the local oscillator is the geometric center of the component carrier.

[0091] In an embodiment of the present application, when the default position information of a DC subcarrier corresponding to a local oscillator indicates that the default position of the DC subcarrier is the geometric center between the left edge of a first component carrier and the right edge of a second component carrier among at least one component carrier corresponding to the local oscillator, the terminal device may send component carrier information and bandwidth portion information corresponding to the local oscillator to a network device, or may only send component carrier information corresponding to the local oscillator to save signaling overhead.

[0092] As a second possible implementation form, the default position of a DC subcarrier corresponding to a local oscillator is the geometric center between a left edge of a first activated component carrier and a right edge of a second activated component carrier among at least one activated component carrier corresponding to the local oscillator.

[0093] Here, the first activated component carrier is the leftmost activated component carrier in the frequency domain among the at least one activated component carrier corresponding to the local oscillator, and the second activated component carrier is the rightmost activated component carrier in the frequency domain among the at least one activated component carrier corresponding to the local oscillator.

[0094] For example, refer to Fig. 5, which is a schematic diagram of another DC subcarrier default position provided by an embodiment of the present application, in which the local oscillator LO corresponds to three component carriers CC1, CC2 and CC3, where the component carriers CC1 and CC2 are activated component carriers, the default position of the DC subcarrier corresponding to the local oscillator is the geometric center between the left edge of the first activated component carrier and the right edge of the second activated component carrier among the at least one activated component carrier corresponding to the local oscillator, i.e., the geometric center between the left edge of CC1 and the right edge of CC2, as shown in Fig. 5.

[0095] It is further noted that if the local oscillator corresponds to only one activated component carrier, the default position of the DC subcarrier corresponding to the local oscillator is the geometric center of the activated component carrier.

[0096] In an embodiment of the present application, when the default position information of a DC subcarrier corresponding to a local oscillator indicates that the default position of the DC subcarrier is the geometric center between the left edge of a first activated component carrier and the right edge of a second activated component carrier among at least one activated component carrier corresponding to the local oscillator, the terminal device may send component carrier information and bandwidth portion information corresponding to the local oscillator to the network device, or may only send component carrier information corresponding to the local oscillator to save signaling overhead.

[0097] As a third possible implementation form, the default position of a DC subcarrier corresponding to a local oscillator is the geometric center between the left edge of a first activated bandwidth portion and the right edge of a second activated bandwidth portion among at least one activated bandwidth portion corresponding to the local oscillator.

[0098] Here, the first activated bandwidth portion is the leftmost activated bandwidth portion in the frequency domain among the at least one activated bandwidth portion corresponding to the local oscillator, and the second bandwidth portion is the rightmost activated bandwidth portion in the frequency domain among the at least one activated bandwidth portion corresponding to the local oscillator.

[0099] For example, refer to Fig. 6, which is a schematic diagram of another DC subcarrier default position provided by an embodiment of the present application, in which the local oscillator LO corresponds to three component carriers CC1, CC2 and CC3, where component carriers CC1 and CC2 are activated component carriers, and the activated bandwidth portion in CC1 is BWP12, and the activated bandwidth portion in CC2 is BWP21. The default position of the DC subcarrier corresponding to the local oscillator is the geometric center between the left edge of the first activated bandwidth portion and the right edge of the second activated bandwidth portion among at least one activated bandwidth portion corresponding to the local oscillator, i.e., the geometric center between the left edge of BWP12 and the right edge of BWP21, as shown in Fig. 6.

[0100] Furthermore, if the local oscillator corresponds to only one activated bandwidth portion, the default position of the DC subcarrier corresponding to the local oscillator is the geometric center of the activated bandwidth portion.

[0101] In an embodiment of the present application, when the default position information of the DC subcarrier corresponding to a certain local oscillator indicates that the default position of the DC subcarrier is the geometric center between the left edge of the first activated bandwidth portion and the right edge of the second activated bandwidth portion among at least one activated bandwidth portion corresponding to the local oscillator, the terminal device may send the component carrier information and the bandwidth portion information corresponding to the local oscillator to the network device, or may send only the bandwidth portion information corresponding to the local oscillator to save signaling overhead. In an embodiment of the present application, the bandwidth portion information is the activated bandwidth portion information. That is, in the example of FIG. 6, the terminal device may send the component carriers CC1, CC2, and CC3 corresponding to the local oscillator LO and the bandwidth portion information BWP12 and BWP21 to the network device, or may send only the bandwidth portion information BWP12 and BWP21 corresponding to the local oscillator LO to save signaling overhead.

[0102] In an embodiment of the present application, optionally, the default position information of the DC subcarrier corresponding to the local oscillator may be reported by at least two bits of information, for example, when the value of the default position information is 1, it indicates that the default position of the DC subcarrier is the default position described in the first possible implementation form, when the value of the default position information is 2, it indicates that the default position of the DC subcarrier is the default position described in the second possible implementation form, when the value of the default position information is 3, it indicates that the default position of the DC subcarrier is the default position described in the third possible implementation form, etc.

[0103] In the embodiment of the present application, the default position information of the DC subcarrier corresponding to each local oscillator may be the same or different.

[0104] In some embodiments, the component carrier and the bandwidth portion can be encoded, and the local oscillator LO corresponding to the component carrier number and the bandwidth portion number in a mapping manner can be included in the DC subcarrier information and transmitted to the network device.

[0105] When the terminal device transmits only the component carrier information or the bandwidth portion information corresponding to the local oscillator, the local oscillator LO corresponding to the component carrier number or the bandwidth portion number is similarly included in the DC subcarrier information in a mapping manner and transmitted to the network device.

[0106] In an embodiment of the present application, the network device can determine an actual position of at least one DC subcarrier of the terminal device based on component carrier information and / or bandwidth portion information corresponding to each local oscillator of the at least one local oscillator transmitted from the terminal device, and default position information of a DC subcarrier corresponding to each local oscillator of the at least one local oscillator.

[0107] It should be noted that the information reporting method provided by the embodiment of the present application can be applied not only to multi-carrier aggregation but also to other communication systems, such as dual connectivity (DC) systems.

[0108] To sum up, by sending DC subcarrier information to a network device, the DC subcarrier information includes: the number of local oscillators of the terminal device, component carrier information and / or bandwidth portion information corresponding to each local oscillator among the at least one local oscillator, and default position information of the DC subcarrier corresponding to each local oscillator among the at least one local oscillator, so that the network device can determine the actual position of the DC subcarrier in the terminal device based on the information reported by the terminal device, which can effectively improve the demodulation performance of the network device, improve communication efficiency, reduce signaling overhead, and improve the universality of the method.

[0109] Please refer to Fig. 7, which is a schematic flowchart of an information reporting method provided by an embodiment of the present application. It should be noted that the information reporting method of the embodiment of the present application is executed by a terminal device. As shown in Fig. 7, the method can include the following steps:

[0110] In step 701, DC subcarrier information is sent to a network device, and the DC subcarrier information includes the number of local oscillators of the terminal device, component carrier information and / or bandwidth portion information corresponding to each local oscillator among the at least one local oscillator, default position information of the DC subcarrier corresponding to each local oscillator among the at least one local oscillator, and offset information of the actual position of the DC subcarrier relative to the default position of the DC subcarrier, where the actual position and the default position have an offset.

[0111] Here, the default position information of the DC subcarrier corresponding to the local oscillator is used to indicate the default position of the DC subcarrier.

[0112] As a first possible implementation form, the default position of a DC subcarrier corresponding to a local oscillator is the geometric center between a left edge of a first component carrier and a right edge of a second component carrier among at least one component carrier corresponding to the local oscillator.

[0113] Here, the first component carrier is the leftmost component carrier in the frequency domain among at least one component carrier corresponding to the local oscillator, and the second component carrier is the rightmost component carrier in the frequency domain among at least one component carrier corresponding to the local oscillator.

[0114] It is further noted that if the local oscillator corresponds to only one component carrier, the default position of the DC subcarrier corresponding to the local oscillator is the geometric center of the component carrier.

[0115] In an embodiment of the present application, when the default position information of a DC subcarrier corresponding to a local oscillator indicates that the default position of the DC subcarrier is the geometric center between the left edge of a first component carrier and the right edge of a second component carrier among at least one component carrier corresponding to the local oscillator, the terminal device may send component carrier information and bandwidth portion information corresponding to the local oscillator to a network device, or may only send component carrier information corresponding to the local oscillator to save signaling overhead.

[0116] As a second possible implementation form, the default position of a DC subcarrier corresponding to a local oscillator is the geometric center between a left edge of a first activated component carrier and a right edge of a second activated component carrier among at least one activated component carrier corresponding to the local oscillator.

[0117] Here, the first activated component carrier is the leftmost activated component carrier in the frequency domain among the at least one activated component carrier corresponding to the local oscillator, and the second activated component carrier is the rightmost activated component carrier in the frequency domain among the at least one activated component carrier corresponding to the local oscillator.

[0118] It is further noted that if the local oscillator corresponds to only one activated component carrier, the default position of the DC subcarrier corresponding to the local oscillator is the geometric center of the activated component carrier.

[0119] In an embodiment of the present application, when the default position information of a DC subcarrier corresponding to a local oscillator indicates that the default position of the DC subcarrier is the geometric center between the left edge of a first activated component carrier and the right edge of a second activated component carrier among at least one activated component carrier corresponding to the local oscillator, the terminal device may send component carrier information and bandwidth portion information corresponding to the local oscillator to the network device, or may only send component carrier information corresponding to the local oscillator to save signaling overhead.

[0120] As a third possible implementation form, the default position of a DC subcarrier corresponding to a local oscillator is the geometric center between the left edge of a first activated bandwidth portion and the right edge of a second activated bandwidth portion among at least one activated bandwidth portion corresponding to the local oscillator.

[0121] Here, the first activated bandwidth portion is the leftmost activated bandwidth portion in the frequency domain among the at least one activated bandwidth portion corresponding to the local oscillator, and the second bandwidth portion is the rightmost activated bandwidth portion in the frequency domain among the at least one activated bandwidth portion corresponding to the local oscillator.

[0122] Furthermore, if the local oscillator corresponds to only one activated bandwidth portion, the default position of the DC subcarrier corresponding to the local oscillator is the geometric center of the activated bandwidth portion.

[0123] In an embodiment of the present application, when the default position information of the DC subcarrier corresponding to a certain local oscillator indicates that the default position of the DC subcarrier is the geometric center between the left edge of the first activated bandwidth portion and the right edge of the second activated bandwidth portion among at least one activated bandwidth portion corresponding to the local oscillator, the terminal device may send the component carrier information and the bandwidth portion information corresponding to the local oscillator to the network device, or may send only the bandwidth portion information corresponding to the local oscillator to save signaling overhead. In an embodiment of the present application, the bandwidth portion information is the activated bandwidth portion information. That is, in the example of FIG. 6, the terminal device may send the component carriers CC1, CC2, and CC3 corresponding to the local oscillator LO and the bandwidth portion information BWP12 and BWP21 to the network device, or may send only the bandwidth portion information BWP12 and BWP21 corresponding to the local oscillator LO to save signaling overhead.

[0124] In an embodiment of the present application, optionally, the default position information of the DC subcarrier corresponding to the local oscillator may be reported by at least two bits of information, for example, when the value of the default position information is 1, it indicates that the default position of the DC subcarrier is the default position described in the first possible implementation form, when the value of the default position information is 2, it indicates that the default position of the DC subcarrier is the default position described in the second possible implementation form, when the value of the default position information is 3, it indicates that the default position of the DC subcarrier is the default position described in the third possible implementation form, etc.

[0125] In an embodiment of the present application, the DC subcarrier information further includes offset information of the actual position of the DC subcarrier relative to the default position of the DC subcarrier, where there is an offset between the actual position and the default position, i.e., in an embodiment of the present application, there is an offset between the actual position of the DC subcarrier corresponding to at least one local oscillator and the default position of the DC subcarrier, and the terminal device further transmits to the network device the offset information of the actual position of the DC subcarrier relative to the default position of the DC subcarrier.

[0126] As an example, refer to FIG. 8, which is a schematic diagram of the actual position of the DC subcarrier provided by the embodiment of the present application. A local oscillator LO1 corresponds to component carriers CC1 and CC2, and a local oscillator LO2 corresponds to component carrier CC3, where the activated bandwidth portion in component carrier CC1 is BWP12, the activated bandwidth portion in component carrier CC2 is BWP21, and the activated bandwidth portion in component carrier CC3 is BWP32. In this example, the default position of the DC subcarrier corresponding to each local oscillator of the terminal device is the geometric center between the left edge of the first activated bandwidth portion and the right edge of the second activated bandwidth portion among at least one activated bandwidth portion corresponding to the local oscillator. That is, the default position of the DC subcarrier corresponding to the local oscillator LO1 is the geometric center between the left edge of the BWP12 and the right edge of the BWP21, and the default position of the DC subcarrier corresponding to the local oscillator LO2 is the geometric center of the BWP32, as shown in FIG. 8. At this time, there is an offset between the actual position and the default position of the DC subcarrier corresponding to the local oscillator LO1, and the offset amount is offset. Therefore, the DC subcarrier information further includes offset information of the actual position of the DC subcarrier corresponding to the local oscillator LO1 relative to the default position.

[0127] Furthermore, if the actual position of the DC subcarrier corresponding to the local oscillator LO2 is not located at the geometric center of the BWP32, the DC subcarrier information of the terminal device needs to include offset information of the actual position of the DC subcarrier corresponding to the local oscillator LO2 relative to the default position.

[0128] It should be noted that the information reporting method provided by the embodiment of the present application can be applied not only to multi-carrier aggregation but also to other communication systems, such as dual connectivity (DC) systems.

[0129] To sum up, by sending DC subcarrier information to a network device, the DC subcarrier information includes: the number of local oscillators of the terminal device, component carrier information and / or bandwidth portion information corresponding to each local oscillator among the at least one local oscillator, default position information of the DC subcarrier corresponding to each local oscillator among the at least one local oscillator, and offset information of the actual position of the DC subcarrier with an offset between the actual position and the default position relative to the default position of the DC subcarrier, so that the network device can determine the actual position of the DC subcarrier in the terminal device based on the information reported by the terminal device, which can effectively improve the demodulation performance of the network device, improve communication efficiency, reduce signaling overhead, and improve the universality of the method.

[0130] Please refer to Fig. 9, which is a schematic flowchart of an information reporting method provided by an embodiment of the present application. It should be noted that the information reporting method of the embodiment of the present application is executed by a network device. As shown in Fig. 9, the method can include the following steps:

[0141] Optionally, the component carrier and the bandwidth portion can be coded, and the local oscillator LO corresponding to the component carrier number and the bandwidth portion number in a mapping manner can be included in the DC subcarrier information and sent to the network device. For example, the local oscillator LO1 corresponds to the component carrier CC1 and the component carrier CC2 and the bandwidth portions BWP11, BWP12, BWP13, BWP14, BWP21, BWP22, BWP23 and BWP24, and the local oscillator LO2 corresponds to the component carrier CC3 and the bandwidth portions BWP31, BWP32, BWP33 and BWP34.

[0142] Furthermore, the bandwidth portion information corresponding to each local oscillator among the at least one local oscillator included in the DC subcarrier information may be activated bandwidth portion information, for example, the activated bandwidth portion in the component carrier CC1 is BWP11, the activated bandwidth portion in the component carrier CC2 is BWP22, and the activated bandwidth portion in the component carrier CC3 is BWP31, and the local oscillator LO1 included in the DC subcarrier information corresponds to the component carrier CC1 and the component carrier CC2 and the bandwidth portions BWP11 and BWP22, and the local oscillator LO2 corresponds to the component carrier CC3 and the bandwidth portion BWP31.

[0148] In step 902, an actual location of at least one DC subcarrier of the terminal device is determined based on the DC subcarrier information.

[0149] In an embodiment of the present application, the network device can determine the actual location of the DC subcarrier of the terminal device based on the received DC subcarrier information.

[0150] In some embodiments, the network device can determine an actual location of a DC subcarrier of the terminal device based on component carrier information and / or bandwidth portion information corresponding to each local oscillator of the at least one received local oscillator.

[0151] It should be noted that the information reporting method provided by the embodiment of the present application can be applied not only to multi-carrier aggregation but also to other communication systems, such as dual connectivity (DC) systems.

[0153] Please refer to Fig. 10, which is a schematic flowchart of an information reporting method provided by an embodiment of the present application. It should be noted that the information reporting method of the embodiment of the present application is executed by a network device. As shown in Fig. 10, the method can include the following steps:

[0154] In step 1001, DC subcarrier information transmitted from a terminal device is received, and the DC subcarrier information includes the number of local oscillators of the terminal device, component carrier information and / or bandwidth portion information corresponding to each local oscillator among the at least one local oscillator, and default position information of the DC subcarrier corresponding to each local oscillator among the at least one local oscillator.

[0155] Here, the default position information of the DC subcarrier corresponding to the local oscillator is used to indicate the default position of the DC subcarrier.

[0156] As a first possible implementation form, the default position of a DC subcarrier corresponding to a local oscillator is the geometric center between a left edge of a first component carrier and a right edge of a second component carrier among at least one component carrier corresponding to the local oscillator.

[0157] Here, the first component carrier is the leftmost component carrier in the frequency domain among at least one component carrier corresponding to the local oscillator, and the second component carrier is the rightmost component carrier in the frequency domain among at least one component carrier corresponding to the local oscillator.

[0158] For example, referring to Fig. 4, the local oscillator LO corresponds to three component carriers CC1, CC2 and CC3, and the default position of the DC subcarrier corresponding to the local oscillator is the geometric center between the left edge of the first component carrier and the right edge of the second component carrier among at least one component carrier corresponding to the local oscillator, that is, the geometric center between the left edge of CC1 and the right edge of CC3 as shown in Fig. 4.

[0159] It is further noted that if the local oscillator corresponds to only one component carrier, the default position of the DC subcarrier corresponding to the local oscillator is the geometric center of the component carrier.

[0160] In the embodiment of the present application, when the default position information of the DC subcarrier corresponding to a local oscillator indicates that the default position of the DC subcarrier is the geometric center between the left edge of the first component carrier and the right edge of the second component carrier among at least one component carrier corresponding to the local oscillator, the terminal device may send the component carrier information and the bandwidth portion information corresponding to the local oscillator to the network device, and may only send the component carrier information corresponding to the local oscillator to save signaling overhead. That is, the network device can determine the default position of the DC subcarrier corresponding to the local oscillator based only on the component carrier information corresponding to the local oscillator, and further determine the actual position of the DC subcarrier.

[0161] As a second possible implementation form, the default position of a DC subcarrier corresponding to a local oscillator is the geometric center between a left edge of a first activated component carrier and a right edge of a second activated component carrier among at least one activated component carrier corresponding to the local oscillator.

[0162] Here, the first activated component carrier is the leftmost activated component carrier in the frequency domain among the at least one activated component carrier corresponding to the local oscillator, and the second activated component carrier is the rightmost activated component carrier in the frequency domain among the at least one activated component carrier corresponding to the local oscillator.

[0163] For example, referring to Fig. 5, the local oscillator LO corresponds to three component carriers CC1, CC2 and CC3, where the component carriers CC1 and CC2 are activated component carriers, and the default position of the DC subcarrier corresponding to the local oscillator is the geometric center between the left edge of the first activated component carrier and the right edge of the second activated component carrier among the at least one activated component carrier corresponding to the local oscillator, i.e., the geometric center between the left edge of CC1 and the right edge of CC2, as shown in Fig. 5.

[0164] It is further noted that if the local oscillator corresponds to only one activated component carrier, the default position of the DC subcarrier corresponding to the local oscillator is the geometric center of the activated component carrier.

[0165] In an embodiment of the present application, when the default position information of a DC subcarrier corresponding to a local oscillator indicates that the default position of the DC subcarrier is the geometric center between the left edge of a first activated component carrier and the right edge of a second activated component carrier among at least one activated component carrier corresponding to the local oscillator, the terminal device may send the component carrier information and bandwidth portion information corresponding to the local oscillator to the network device, or may only send the component carrier information corresponding to the local oscillator to save signaling overhead. That is, the network device can determine the default position of the DC subcarrier corresponding to the local oscillator based only on the component carrier information corresponding to the local oscillator, and further determine the actual position of the DC subcarrier.

[0166] As a third possible implementation form, the default position of a DC subcarrier corresponding to a local oscillator is the geometric center between the left edge of a first activated bandwidth portion and the right edge of a second activated bandwidth portion among at least one activated bandwidth portion corresponding to the local oscillator.

[0167] Here, the first activated bandwidth portion is the leftmost activated bandwidth portion in the frequency domain among the at least one activated bandwidth portion corresponding to the local oscillator, and the second bandwidth portion is the rightmost activated bandwidth portion in the frequency domain among the at least one activated bandwidth portion corresponding to the local oscillator.

[0168] For example, refer to Fig. 6, which is a schematic diagram of another DC subcarrier default position provided by an embodiment of the present application, in which the local oscillator LO corresponds to three component carriers CC1, CC2 and CC3, where component carriers CC1 and CC2 are activated component carriers, and the activated bandwidth portion in CC1 is BWP12, and the activated bandwidth portion in CC2 is BWP21. The default position of the DC subcarrier corresponding to the local oscillator is the geometric center between the left edge of the first activated bandwidth portion and the right edge of the second activated bandwidth portion among at least one activated bandwidth portion corresponding to the local oscillator, i.e., the geometric center between the left edge of BWP12 and the right edge of BWP21, as shown in Fig. 6.

[0169] Furthermore, if the local oscillator corresponds to only one activated bandwidth portion, the default position of the DC subcarrier corresponding to the local oscillator is the geometric center of the activated bandwidth portion.

[0170] In an embodiment of the present application, when the default position information of a DC subcarrier corresponding to a certain local oscillator indicates that the default position of the DC subcarrier is the geometric center between the left edge of the first activated bandwidth portion and the right edge of the second activated bandwidth portion among at least one activated bandwidth portion corresponding to the local oscillator, the terminal device may transmit the component carrier information and the bandwidth portion information corresponding to the local oscillator to the network device, or may transmit only the bandwidth portion information corresponding to the local oscillator to save signaling overhead. That is, the network device can determine the default position of the DC subcarrier corresponding to the local oscillator based only on the bandwidth portion information corresponding to the local oscillator, and further determine the actual position of the DC subcarrier. In an embodiment of the present application, the bandwidth portion information is the activated bandwidth portion information. That is, in the example of Figure 6, the terminal device may transmit component carriers CC1, CC2 and CC3 corresponding to the local oscillator LO and bandwidth portion information BWP12 and BWP21 to the network device, or may transmit only the bandwidth portion information BWP12 and BWP21 corresponding to the local oscillator LO to save signaling overhead.

[0172] In the embodiment of the present application, the default position information of the DC subcarrier corresponding to each local oscillator may be the same or different.

[0173] In some embodiments, the component carrier and the bandwidth portion can be encoded, and the local oscillator LO corresponding to the component carrier number and the bandwidth portion number in a mapping manner can be included in the DC subcarrier information and transmitted to the network device.

[0174] When the terminal device transmits only the component carrier information or the bandwidth portion information corresponding to the local oscillator, the local oscillator LO corresponding to the component carrier number or the bandwidth portion number is similarly included in the DC subcarrier information in a mapping manner and transmitted to the network device.

[0175] In an embodiment of the present application, the network device can determine an actual position of at least one DC subcarrier of the terminal device based on component carrier information and / or bandwidth portion information corresponding to each local oscillator of the at least one local oscillator transmitted from the terminal device, and default position information of a DC subcarrier corresponding to each local oscillator of the at least one local oscillator.

[0176] In step 1002, determine an actual location of at least one DC subcarrier of the terminal device based on the DC subcarrier information.

[0177] In an embodiment of the present application, the network device can determine the actual location of the DC subcarrier of the terminal device based on the received DC subcarrier information.

[0178] The network device can receive default position information of a DC subcarrier corresponding to each local oscillator among the at least one local oscillator transmitted from the terminal device, and component carrier information and / or bandwidth portion information corresponding to each local oscillator among the at least one local oscillator, determine a default position of the DC subcarrier indicated by the default position information, and further determine an actual position of the DC subcarrier.

[0179] It should be noted that the information reporting method provided by the embodiment of the present application can be applied not only to multi-carrier aggregation but also to other communication systems, such as dual connectivity (DC) systems.

[0180] To sum up, receive DC subcarrier information sent from a terminal device, the DC subcarrier information including: the number of local oscillators of the terminal device, component carrier information and / or bandwidth portion information corresponding to each local oscillator among the at least one local oscillator, and default position information of the DC subcarrier corresponding to each local oscillator among the at least one local oscillator; and determine an actual position of at least one DC subcarrier of the terminal device based on the DC subcarrier information, so that the network device can determine the actual position of the DC subcarrier in the terminal device based on the information reported by the terminal device, which can effectively improve the demodulation performance of the network device, improve communication efficiency, reduce signaling overhead, and improve the universality of the method.

[0181] Please refer to Fig. 11, which is a schematic flowchart of an information reporting method provided by an embodiment of the present application. It should be noted that the information reporting method of the embodiment of the present application is executed by a network device. As shown in Fig. 11, the method can include the following steps:

[0182] In step 1101, DC subcarrier information transmitted from a terminal device is received, and the DC subcarrier information includes the number of local oscillators of the terminal device, component carrier information and / or bandwidth portion information corresponding to each local oscillator among the at least one local oscillator, default position information of the DC subcarrier corresponding to each local oscillator among the at least one local oscillator, and offset information of the actual position of the DC subcarrier relative to the default position of the DC subcarrier, where the actual position and the default position have an offset.

[0183] Here, the default position information of the DC subcarrier corresponding to the local oscillator is used to indicate the default position of the DC subcarrier.

[0184] As a first possible implementation form, the default position of a DC subcarrier corresponding to a local oscillator is the geometric center between a left edge of a first component carrier and a right edge of a second component carrier among at least one component carrier corresponding to the local oscillator.

[0185] Here, the first component carrier is the leftmost component carrier in the frequency domain among at least one component carrier corresponding to the local oscillator, and the second component carrier is the rightmost component carrier in the frequency domain among at least one component carrier corresponding to the local oscillator.

[0186] It is further noted that if the local oscillator corresponds to only one component carrier, the default position of the DC subcarrier corresponding to the local oscillator is the geometric center of the component carrier.

[0187] In the embodiment of the present application, when the default position information of the DC subcarrier corresponding to a local oscillator indicates that the default position of the DC subcarrier is the geometric center between the left edge of the first component carrier and the right edge of the second component carrier among at least one component carrier corresponding to the local oscillator, the terminal device may send the component carrier information and the bandwidth portion information corresponding to the local oscillator to the network device, and may only send the component carrier information corresponding to the local oscillator to save signaling overhead. That is, the network device can determine the default position of the DC subcarrier corresponding to the local oscillator based only on the component carrier information corresponding to the local oscillator, and further determine the actual position of the DC subcarrier.

[0188] As a second possible implementation form, the default position of a DC subcarrier corresponding to a local oscillator is the geometric center between a left edge of a first activated component carrier and a right edge of a second activated component carrier among at least one activated component carrier corresponding to the local oscillator.

[0189] Here, the first activated component carrier is the leftmost activated component carrier in the frequency domain among the at least one activated component carrier corresponding to the local oscillator, and the second activated component carrier is the rightmost activated component carrier in the frequency domain among the at least one activated component carrier corresponding to the local oscillator.

[0190] It is further noted that if the local oscillator corresponds to only one activated component carrier, the default position of the DC subcarrier corresponding to the local oscillator is the geometric center of the activated component carrier.

[0191] In an embodiment of the present application, when the default position information of a DC subcarrier corresponding to a local oscillator indicates that the default position of the DC subcarrier is the geometric center between the left edge of a first activated component carrier and the right edge of a second activated component carrier among at least one activated component carrier corresponding to the local oscillator, the terminal device may send the component carrier information and bandwidth portion information corresponding to the local oscillator to the network device, or may only send the component carrier information corresponding to the local oscillator to save signaling overhead. That is, the network device can determine the default position of the DC subcarrier corresponding to the local oscillator based only on the component carrier information corresponding to the local oscillator, and further determine the actual position of the DC subcarrier.

[0192] As a third possible implementation form, the default position of a DC subcarrier corresponding to a local oscillator is the geometric center between the left edge of a first activated bandwidth portion and the right edge of a second activated bandwidth portion among at least one activated bandwidth portion corresponding to the local oscillator.

[0193] Here, the first activated bandwidth portion is the leftmost activated bandwidth portion in the frequency domain among the at least one activated bandwidth portion corresponding to the local oscillator, and the second bandwidth portion is the rightmost activated bandwidth portion in the frequency domain among the at least one activated bandwidth portion corresponding to the local oscillator.

[0194] Furthermore, if the local oscillator corresponds to only one activated bandwidth portion, the default position of the DC subcarrier corresponding to the local oscillator is the geometric center of the activated bandwidth portion.

[0195] In an embodiment of the present application, when the default position information of a DC subcarrier corresponding to a certain local oscillator indicates that the default position of the DC subcarrier is the geometric center between the left edge of the first activated bandwidth portion and the right edge of the second activated bandwidth portion among at least one activated bandwidth portion corresponding to the local oscillator, the terminal device may transmit the component carrier information and the bandwidth portion information corresponding to the local oscillator to the network device, or may transmit only the bandwidth portion information corresponding to the local oscillator to save signaling overhead. That is, the network device can determine the default position of the DC subcarrier corresponding to the local oscillator based only on the bandwidth portion information corresponding to the local oscillator, and further determine the actual position of the DC subcarrier. In an embodiment of the present application, the bandwidth portion information is the activated bandwidth portion information. That is, in the example of Figure 6, the terminal device may transmit component carriers CC1, CC2 and CC3 corresponding to the local oscillator LO and bandwidth portion information BWP12 and BWP21 to the network device, or may transmit only the bandwidth portion information BWP12 and BWP21 corresponding to the local oscillator LO to save signaling overhead.

[0196] In an embodiment of the present application, optionally, the default position information of the DC subcarrier corresponding to the local oscillator may be reported by at least two bits of information, for example, when the value of the default position information is 1, it indicates that the default position of the DC subcarrier is the default position described in the first possible implementation form, when the value of the default position information is 2, it indicates that the default position of the DC subcarrier is the default position described in the second possible implementation form, when the value of the default position information is 3, it indicates that the default position of the DC subcarrier is the default position described in the third possible implementation form, etc.

[0197] In an embodiment of the present application, the DC subcarrier information further includes offset information of the actual position of the DC subcarrier relative to the default position of the DC subcarrier, where there is an offset between the actual position and the default position, i.e., in an embodiment of the present application, there is an offset between the actual position of the DC subcarrier corresponding to at least one local oscillator and the default position of the DC subcarrier, and the terminal device further transmits to the network device the offset information of the actual position of the DC subcarrier relative to the default position of the DC subcarrier.

[0198] As an example, refer to FIG. 8, which is a schematic diagram of the actual position of the DC subcarrier provided by the embodiment of the present application. A local oscillator LO1 corresponds to component carriers CC1 and CC2, and a local oscillator LO2 corresponds to component carrier CC3, where the activated bandwidth portion in component carrier CC1 is BWP12, the activated bandwidth portion in component carrier CC2 is BWP21, and the activated bandwidth portion in component carrier CC3 is BWP32. In this example, the default position of the DC subcarrier corresponding to each local oscillator of the terminal device is the geometric center between the left edge of the first activated bandwidth portion and the right edge of the second activated bandwidth portion among at least one activated bandwidth portion corresponding to the local oscillator. That is, the default position of the DC subcarrier corresponding to the local oscillator LO1 is the geometric center between the left edge of the BWP12 and the right edge of the BWP21, and the default position of the DC subcarrier corresponding to the local oscillator LO2 is the geometric center of the BWP32, as shown in FIG. 8. At this time, there is an offset between the actual position and the default position of the DC subcarrier corresponding to the local oscillator LO1, and the offset amount is offset. Therefore, the DC subcarrier information further includes offset information of the actual position of the DC subcarrier corresponding to the local oscillator LO1 relative to the default position.

[0199] Furthermore, if the actual position of the DC subcarrier corresponding to the local oscillator LO2 is not located at the geometric center of the BWP32, the DC subcarrier information of the terminal device needs to include offset information of the actual position of the DC subcarrier corresponding to the local oscillator LO2 relative to the default position.

[0200] In step 1102, determine an actual location of at least one DC subcarrier of the terminal device based on the DC subcarrier information.

[0201] In an embodiment of the present application, the network device can determine the actual location of the DC subcarrier of the terminal device based on the received DC subcarrier information.

[0202] The network device can receive default position information of the DC subcarrier corresponding to each local oscillator of the at least one local oscillator transmitted from the terminal device, and component carrier information and / or bandwidth portion information corresponding to each local oscillator of the at least one local oscillator, determine a default position of the DC subcarrier indicated by the default position information, and further determine an actual position of the DC subcarrier. In response to there being an offset between the actual position and the default position of the DC subcarrier, the network device can determine the actual position of the DC subcarrier having the offset based on the offset information in the DC subcarrier information.

[0203] It should be noted that the information reporting method provided by the embodiment of the present application can be applied not only to multi-carrier aggregation but also to other communication systems, such as dual connectivity (DC) systems.

[0204] To sum up, receive DC subcarrier information sent from a terminal device, the DC subcarrier information including: the number of local oscillators of the terminal device, component carrier information and / or bandwidth portion information corresponding to each local oscillator among the at least one local oscillator, default position information of DC subcarriers corresponding to each local oscillator among the at least one local oscillator, and offset information of the actual position of the DC subcarrier, the actual position of which has an offset between the actual position and the default position, relative to the default position of the DC subcarrier; and determine an actual position of at least one DC subcarrier of the terminal device based on the DC subcarrier information, so that the network device can determine the actual position of the DC subcarrier in the terminal device based on the information reported by the terminal device, which can effectively improve the demodulation performance of the network device, improve communication efficiency, reduce signaling overhead, and improve the universality of the method.
