Message processing method and device

Technical Field

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

Background

In the fifth generation mobile network (5 g) communication, a terminal may communicate with a network device on different cells. Illustratively, the network device may configure a plurality of cells (cells) for the terminal, and configure one or more bandwidth parts (BWPs) in each cell, so that the terminal communicates with the network device through different BWPs.

Currently, a terminal may report a Direct Current (DC) location corresponding to a Component Carrier (CC) and a BWP to a network device, so that the network device optimizes data transmission with the terminal through the BWP according to the DC location. Specifically, when the network device configures a plurality of cells for the terminal, and each cell is configured with a plurality of BWPs, for each cell in the plurality of cells, the terminal may report a DC location corresponding to any BWP in the plurality of BWPs of the cell to the network device. So that during communication, the network device can determine the corresponding DC location based on the activated BWP, optimizing the corresponding data transmission. Further, under intra-band (intra-band) uplink Carrier Aggregation (CA), for two CCs in the combination, the terminal may report a DC position corresponding to any BWP combination in a plurality of BWP combinations corresponding to the two CCs to the network device, so that in the communication process, the network device may determine the corresponding DC position according to the activated BWP combination, that is, a BWP pair (BWP pair) formed by one activated BWP in each CC, and optimize corresponding data transmission.

However, in a Carrier Aggregation (CA) communication scenario, when a terminal has multiple channels and the number of CCs associated with a DC location exceeds two CCs, a network device cannot know the relationship between the multiple channels and the DC location, and thus cannot know the DC location of each channel in current communication, and further cannot optimize data transmission accordingly.

For example, at least one (one) of a, b, or c, may represent: a. b, c, a-b, a-c, b-c, or a-b-c, wherein a, b, c can be single or multiple. In addition, in the embodiments of the present application, the words "first", "second", and the like do not limit the number and the execution order.

It is noted that, in the present application, words such as "exemplary" or "for example" are used to mean exemplary, illustrative, or descriptive. Any embodiment or design described herein as "exemplary" or "e.g.," is not necessarily to be construed as preferred or advantageous over other embodiments or designs. Rather, use of the word "exemplary" or "such as" is intended to present concepts related in a concrete fashion.

The technical solutions in the embodiments of the present application will be described below with reference to the drawings in the embodiments of the present application.

In the communication process, the network device may determine, through a Direct Current (DC) position reported by the terminal, a position of local oscillator leakage (lo leakage) of a carrier corresponding to a cell (cell) in a frequency domain in the communication process, and accordingly perform corresponding processing on the local oscillator leakage position, for example, recover or selectively discard a data block transmitted at a frequency corresponding to the local oscillator leakage position, so as to improve quality of data transmission on the carrier of the cell.

In a Long Term Evolution (LTE) system, a default DC position is generally located on a Resource Element (RE) at the center of a frequency domain corresponding to a cell carrier, that is, a frequency corresponding to the DC position corresponding to a cell is generally located on a central frequency point of a frequency domain bandwidth corresponding to a corresponding cell carrier. The network device may determine the DC position according to the frequency domain bandwidth corresponding to the cell carrier, and perform a targeted process on the DC position.

Different from the LTE system, in a fifth generation mobile communication technology (5 g) system, a frequency corresponding to a DC position may be set at any position on a frequency domain bandwidth of a corresponding cell carrier, and therefore, a network device needs to report the DC position through a terminal to determine a local oscillator leakage position of the corresponding cell carrier, so as to perform corresponding processing accordingly and improve quality of data transmission.

It should be noted that, in the 5G system, the frequency domain bandwidth (or called system bandwidth (CBW)) corresponding to the cell carrier may be divided into a plurality of different bandwidth groups (BWPs) for communication, and the positions of the different BWPs on the cell carrier may be flexibly configured. Each BWP may correspond to a DC location. Therefore, when the terminal reports the DC location to the network device, the DC location corresponding to each BWP needs to be reported to the network device, so that the network device determines the DC location of the current communication according to the BWP activated in the current communication process. In the embodiment of the present application, BWP on a cell carrier may be referred to as BWP of a cell.

For example, the network device may send an indication message to the terminal, where the indication message is used to indicate that the terminal reports the DC position of the BWP configured for the terminal by the network device. A network device is taken as a terminal to configure 2 cells (e.g., cell 1 and cell 2), and each cell includes 2 BWPs (e.g., cell 1 includes BWP11 and BWP12, and cell 2 includes BWP21 and BWP 22). After receiving the indication message for reporting the DC location sent by the network device, the terminal may report the DC location of each BWP to the network device, respectively. For example, the DC position DC11 corresponding to BWP11, the DC position DC12 corresponding to BWP12, the DC position DC21 corresponding to BWP21, and the DC position DC22 corresponding to BWP22 are reported to the network device. So that when a corresponding BWP is activated, the network device can determine the frequency location of the local oscillator leakage of the current communication according to the corresponding DC location, and then optimize the data transmission accordingly.

In addition, in the data transmission of the 5G system, there are a large number of scenarios in which a plurality of BWPs are simultaneously activated for data transmission. For example, in a Carrier Aggregation (CA) communication scenario, such as intra-band CA (intra-band CA) communication or inter-band CA (inter-band CA) communication, among a plurality of cells configured for a terminal by a network device, there may be two or more cells each of which may have one activated BWP. As an overall transmission process, a CA communication process only corresponds to one local oscillator leakage position, that is, only corresponds to one DC position. At this time, the terminal may report DC positions corresponding to any two BWPs in a CC pair (pair) formed by any two CCs among a plurality of Component Carriers (CCs) configured by the network device, where any two BWPs are located in different CCs in the CC pair respectively. So that during communication, the network device can determine the corresponding DC location based on the activated BWP, optimizing the corresponding data transmission.

However, when the terminal has at least two channels and the number of aggregated carriers is at least three CCs, the network device cannot know the mapping relationship between the multiple channels and the CCs, and thus cannot know the DC position corresponding to each channel, and therefore cannot know the DC position of each channel in the current communication, and further cannot optimize data transmission accordingly. In order to solve the foregoing problem, an embodiment of the present application provides a message processing method, which enables a network device to know a DC position corresponding to each of at least two channels, and further can actively manage the communication accordingly, for example, correspondingly process a data block corresponding to the DC position.

The following describes a message processing method provided in an embodiment of the present application in detail with reference to the accompanying drawings.

Please refer to fig. 1, which is a block diagram of a communication system 100 according to an embodiment of the present disclosure. As shown in fig. 1, the communication system 100 may include a terminal 110 and a network device 120. Other terminals besides 110 may also be included in the communication system 100, for example, the terminal 130 shown in fig. 1 may also be included in the communication system 100. The number of terminals included in the communication system 100 is not limited in the embodiment of the present application. For example, the terminal (also referred to as a terminal device) in the embodiment of the present application may be a User Equipment (UE), a mobile phone, a tablet computer, a desktop computer, a laptop computer, a handheld computer, a notebook computer, an ultra-mobile personal computer (UMPC), a netbook, and an electronic device capable of supporting 5G communication, such as a cellular phone, a Personal Digital Assistant (PDA), an Augmented Reality (AR) \ Virtual Reality (VR) device, a media player, and the embodiment of the present application does not particularly limit the specific form of the device.

In the communication system 100, the network device 120 may be a 5G base station. It should be understood that in other embodiments, the network device 120 may also be a third Generation mobile communication technology (3 rd-Generation, 3G) or fourth Generation mobile communication technology (4G) base station capable of supporting 5G communication, or other communication devices. Illustratively, when the network device 120 is a 5G base station, a 5G New Radio (NR) can be provided for 5G communication with other devices (e.g., the terminal 110 and/or the terminal 130). In some embodiments, the network device 120 can include a transmitter chain and a receiver chain, each of which can include components associated with signal transmission and reception (e.g., processors, modulators, multiplexers, encoders, demultiplexers, or antennas, etc.), as will be appreciated by one of ordinary skill in the art.

As shown in fig. 1, terminal 110 may communicate with network device 120. Where network device 120 may transmit information to terminal 110 over forward link 110-1 (which may also be referred to as a downlink) and receive information from terminal 110 over reverse link 110-2 (which may also be referred to as an uplink). Similarly, terminal 130 may also communicate with network device 120. Where network device 120 transmits information to terminal 130 over forward link 130-1 and receives information from terminal 130 over reverse link 130-2. As an example, network device 120 is in data communication with terminal 110. In some embodiments, network device 120 may send a message a to terminal 110 over downlink 110-1 instructing terminal 110 to feed back to network device 120 the DC location corresponding to each BWP configured for it. In response to this message a, terminal 110 may send the DC location for each BWP to network device 120 via uplink 110-2. In other embodiments, the network device may send a message B to the terminal 110 via the downlink 110-2, which is used to instruct the terminal 110 to feed back to the network device 120 the DC location of the corresponding communication when all possible arbitrary two BWPs in all BWPs configured for the terminal are activated simultaneously. In response to this message B, terminal 110 may send all DC locations of corresponding communications in all BWPs, all possible pairwise in a group, when activated, to network device 120 via uplink 110-2.

It should be noted that the communication system 100 may be a Public Land Mobile Network (PLMN) or a device-to-device (D2D) Network or a machine-to-machine (M2M) Network or other networks, and fig. 1 is a simplified schematic diagram for example, and other Network devices may be included in the Network, which is not shown in fig. 1.

Fig. 2 is a flowchart of a message processing method according to an embodiment of the present application, where the method may be applied to the communication system 100 shown in fig. 1 to solve the problem of reporting the DC location when at least two channels of a terminal correspond to at least three CCs, and the method may include the following steps.

The first message may also be a control element (MAC CE) entity message of the medium access control layer, such as a periodic MAC CE report, and for example, a MAC CE report triggered by an event, where the triggering event may include: activating a cell, deactivating the cell, switching BWP, switching the cell, changing the channel bandwidth, and changing the state of Discontinuous Reception (DRX).

In addition, the DC position may specifically refer to a Resource Element (RE) position, and a center frequency of the DC position corresponding frequency is a frequency corresponding to the RE position of the resource element. The DC position may specifically be a frequency point position corresponding to an Absolute Radio Frequency Channel Number (ARFCN), or may be a frequency point position corresponding to an offset from a reference frequency point position.

In one embodiment, the first message may be used to indicate the CC corresponding to each of the M lanes. When a certain channel of the M channels corresponds to only one CC, the first message may further be used to indicate a set of DC positions corresponding to the configured BWP in the CC; when a certain channel of the M channels corresponds to multiple CCs, the first message may further be used to indicate DC positions corresponding to BWPs configured in any two CC pairs composed of any two CCs of the multiple configured CCs, where the any two BWPs are respectively located in different CCs of the CC pairs.

For example, as shown in fig. 3, assuming that the M channels include 2 channels and are respectively denoted as PA1 and PA2 (the PA1 corresponds to the local oscillator LO1, and the PA2 corresponds to the local oscillator LO 2), the N CCs include 4 CCs and are respectively denoted as CC1, CC2, CC3, and CC4, the CC corresponding to PA1 includes CC1, CC2, and CC3, and the CC corresponding to PA2 includes CC4, the first message may be used to indicate the following: the CC corresponding to the PA1 comprises CC1, CC2 and CC3, and the CC corresponding to the PA2 comprises CC4; the DC position of PA1 includes DC positions corresponding to any two BWPs in a CC pair consisting of any two CCs of CC1 to CC3, and the DC position of PA2 includes DC positions corresponding to BWPs in CC 4. Illustratively, as shown in fig. 4, if CC1 includes four BWPs (11, 12, 13 and 14, respectively), CC2 includes four BWPs (21, 22, 23 and 14, respectively), and CC3 includes four BWPs (21, 22, 23 and 14, respectively)Denoted 31, 32, 33, and 34), CC4 includes four BWPs (denoted 41, 42, 43, and 44, respectively), then the first message may be used to indicate: the DC position corresponding to the CC pair consisting of CC1 and CC2 comprises DC _11-21 、DC _12-21 、DC _13-21 、DC _14-21 、DC _11-22 、DC _12-22 、DC _13-22 、DC _14-22 、DC _11-23 、DC _12-23 、DC _13-23 、DC _14-23 、DC _11-24 、DC _12-24 、DC _13-24 、DC _14-24 (ii) a The DC position corresponding to the CC pair formed by the CC2 and the CC3 comprises DC _21-31 、DC _22-31 、DC _23-31 、DC _24-31 、DC _21-32 、DC _22-32 、DC _23-32 、DC _24-32 、DC _21-33 、DC _22-33 、DC _23-33 、DC _24-33 、DC _21-34 、DC _22-34 、DC _23-34 、DC _24-34 (ii) a The DC position corresponding to the CC pair formed by the CC1 and the CC3 comprises DC _11-31 、DC _12-31 、DC _13-31 、DC _14-31 、DC _11-32 、DC _12-32 、DC _13-32 、DC _14-32 、DC _11-33 、DC _12-33 、DC _13-33 、DC _14-33 、DC _11-34 、DC _12-34 、DC _13-34 、DC _14-34 (ii) a The DC location corresponding to CC4 includes DC ₄₁ 、DC ₄₂ 、DC ₄₃ And DC ₄₄ 。

Further, in another embodiment, the first message may be used to indicate a CC corresponding to each of the M channels. When a certain channel of the M channels corresponds to only one CC, the first message may also be used to indicate a DC position corresponding to an active BWP in the CC; when a certain channel of the M channels corresponds to multiple CCs, the first message may be further used to indicate a DC position corresponding to BWPs configured in any two of the current multiple activated CCs, or a DC position corresponding to a combination of the activated BWPs in the current multiple activated CCs.

For example, as shown in fig. 5, it is assumed that the M channels include 2 channels and are respectively denoted as PA1 and PA2 (PA 1 corresponds to local oscillator LO1, PA2 corresponds to local oscillator LO 2),the N CCs include 6 CCs and are respectively denoted as CC1 to CC6, the CC corresponding to PA1 includes CC1, CC2, CC3, and CC4, the CC corresponding to PA2 includes CC5 and CC6, the activated CCs in the CCs corresponding to PA1 are CC1, CC2, and CC3 in the current communication state, and the activated CCs in the CCs corresponding to PA2 are CC5, then the first message may be used to indicate the following: the CC corresponding to the PA1 comprises CC1, CC2 and CC3, and the CC corresponding to the PA2 comprises CC5; the DC position of PA1 includes a DC position corresponding to BWP configured in any two CC pairs consisting of any two CCs from CC1 to CC3, and the DC position of PA2 includes a DC position corresponding to BWP in CC 5. Illustratively, as shown in fig. 6, if CC1 includes four BWPs (denoted 11, 12, 13, and 14, respectively), CC2 includes four BWPs (denoted 21, 22, 23, and 14, respectively), CC3 includes four BWPs (denoted 31, 32, 33, and 34, respectively), and CC5 includes four BWPs (denoted 51, 52, 53, and 54, respectively), then the first message may be used to indicate: the DC position corresponding to the CC pair formed by the CC1 and the CC2 comprises DC _11-21 、DC _12-21 、DC _13-21 、DC _14-21 、DC _11-22 、DC _12-22 、DC _13-22 、DC _14-22 、DC _11-23 、DC _12-23 、DC _13-23 、DC _14-23 、DC _11-24 、DC _12-24 、DC _13-24 、DC _14-24 (ii) a The DC position corresponding to the CC pair consisting of CC2 and CC3 comprises DC _21-31 、DC _22-31 、DC _23-31 、DC _24-31 、DC _21-32 、DC _22-32 、DC _23-32 、DC _24-32 、DC _21-33 、DC _22-33 、DC _23-33 、DC _24-33 、DC _21-34 、DC _22-34 、DC _23-34 、DC _24-34 (ii) a The DC position corresponding to the CC pair consisting of CC1 and CC3 comprises DC _11-31 、DC _12-31 、DC _13-31 、DC _14-31 、DC _11-32 、DC _12-32 、DC _13-32 、DC _14-32 、DC _11-33 、DC _12-33 、DC _13-33 、DC _14-33 、DC _11-34 、DC _12-34 、DC _13-34 、DC _14-34 (ii) a The DC location corresponding to CC5 includes DC ₅₁ 、DC ₅₂ 、DC ₅₃ And DC ₅₄ 。

Further, in yet another embodiment, the first message may be used to indicate a CC corresponding to each of the M channels. When a certain channel of the M channels corresponds to only one CC, the first message may also be used to indicate a DC position corresponding to an active BWP in the CC; when a certain channel of the M channels corresponds to multiple CCs, the first message may be further used to indicate a DC position corresponding to BWPs activated by any two currently activated multiple CCs, or a DC position corresponding to a combination of the activated BWPs in the currently activated multiple CCs. Assuming that the M channels include 2 channels and are respectively denoted as PA1 and PA2, the N CCs include 4 CCs and are respectively denoted as CC1, CC2, CC3, and CC4, the CC corresponding to PA1 includes CC1, CC2, CC3, and CC4, the CC corresponding to PA2 includes CC5 and CC6, the activated CC in the CC corresponding to PA1 is CC1, CC2 and CC3 in the current communication state, and the activated CC in the CC corresponding to PA2 is CC5, the first message may be used to indicate the following: the CC corresponding to the PA1 comprises CC1, CC2 and CC3, and the CC corresponding to the PA2 comprises CC5; the DC position of PA1 is a DC position corresponding to a BWP combination composed of activated BWPs for each CC of CC1 to CC3, and the DC position of PA2 is a DC position corresponding to an activated BWP in CC 5.

As an example, the terminal may transmit the DC location of the terminal in the first message according to an agreed structure. For example, the following shows a structural schematic of a first message.

In one possible implementation, the first message is also used to indicate a cell identity of a CC in which the DC location of the terminal is located. That is, for each of the plurality of DC positions indicated by the first message, the first message is also used to indicate a cell identity of the CC in which the DC position is located.

Optionally, the M channels may be divided according to the number of Power Amplifiers (PAs) included in the terminal, that is, each of the M channels corresponds to one PA.

Alternatively, the M channels may be divided by the number of separation classes (separation classes) of the terminal, i.e., each of the M channels corresponds to one separation class of the terminal. For example, the rf front-end portion of the terminal uses a multi-PA phased array, or when the terminal is used for millimeter wave communication, the M channels may be divided according to the number of separation levels of the terminal.

Further, for inter-band (inter-band) CA communication of millimeter waves, the terminal may also report beam management information of multiple CCs corresponding to the CA to the network device, so that the network device notifies the terminal how to report the DC location according to the beam management information reported by the terminal. Optionally, when the beam management information reported by the terminal to the network device is Independent Beam Management (IBM) information, the network device may instruct the terminal to report the DC location in a manner of the first message; when the beam management information reported by the terminal to the network device is Common Beam Management (CBM) information, the network device may instruct the terminal to report the DC location in an intra-band CA (intra-band CA) manner.

For example, before the terminal sends the first message to the network device, the method may further include: the terminal may further send a second message to the network device, where the second message is used to indicate beam management mode information of multiple CCs corresponding to an aggregated carrier of the terminal; when the network device receives the second message, the network device may send a third message to the terminal, where the third message is used to instruct the terminal to send the first message. Thus, when the terminal receives the third message from the network device, the terminal may send the first message to the network device through the above S201 to report the DC location of the terminal to the network device.

S202: the network device receives a first message. It should be noted that, for the description of the first message in S202, reference may be made to the description in S201, and details of the embodiment of the present application are not described herein again.

S203: the network device determines a current communicated DC location for each of the M channels based on the first message.

Specifically, for each of the M lanes, if the lane corresponds to only one CC, the network device may determine a DC position of an active BWP of the BWPs of the CC as a DC position of current communication of the lane. If the activated CC in the plurality of CCs corresponding to the channel includes at least two CCs, and the first CC with the lowest carrier frequency point and the second CC with the highest carrier frequency point form a first CC pair, and the BWP currently in the activated state in the first CC pair forms a first BWP combination, the network device may query a DC position corresponding to the first BWP combination in the first CC pair from the plurality of DC positions corresponding to the channel as a current communication DC position of the channel. The network device may determine the DC location of the current communication on each of the M channels according to the above rules.

In an embodiment, for each of M channels, if the channel corresponds to only one CC, the network device determines a DC position of an active BWP of the plurality of BWPs of the CC as a DC position of current communication on the channel, or determines a DC position of current communication on the channel according to a reported DC position corresponding to the active BWP; if the channel corresponds to at least two activated CCs in the multiple CCs, determining, by the network device, a DC position of the BWP in an activated state in the BWP combination configured on the multiple activated CCs as a DC position of current communication on the channel; or, if the activated CC in the plurality of CCs corresponding to the channel includes at least two CCs, the network device determines the DC location on the channel according to the reported DC location corresponding to the activated BWP.

In the method provided in the embodiment of the present application, when the terminal has M channels and corresponds to N CCs, the terminal may report, through a first message, a DC location corresponding to a CC corresponding to each channel in the M channels, a DC location corresponding to a BWP in the CC when a certain channel in the M channels corresponds to only one CC, and a DC location corresponding to any two BWPs in a CC pair composed of any two CCs in the multiple CCs when a certain channel in the M channels corresponds to multiple CCs, to the network device, so that the network device may know the DC location of each channel in the M channels, and further query and determine the DC location of a channel used by the terminal for current communication from the DC locations of the M channels, thereby optimizing data transmission.

Fig. 7 is a flowchart of another message processing method according to an embodiment of the present application, where the method may be applied to the communication system 100 shown in fig. 1, and is used to solve a problem of how to coexist in a network when a terminal supports local oscillator leakage self-calibration capability and/or supports DC location reporting, where the method may include the following steps.

S301: the terminal sends a first message to the network equipment, wherein the first message is used for indicating whether the terminal supports a first capability, and the first capability is a local oscillator leakage self-calibration capability. Accordingly, S301a: the network device receives a first message.

Whether the terminal supports the first capability may also be referred to as whether the terminal has the first capability, specifically, whether the terminal has a local oscillator leakage self-calibration capability. The terminal has the local oscillator leakage self-calibration capability, which means that the terminal performs self-calibration optimization on uplink data to be transmitted, so that the local oscillator leakage of a transmission signal is lower than a certain threshold value, and the influence of the local oscillator leakage on the data can be ignored. The fact that one terminal does not have the local oscillator leakage self-calibration capability means that the terminal cannot perform self-calibration optimization processing on uplink data to be transmitted, so that the local oscillator leakage of a transmission signal is lower than a certain threshold value, and the influence of the local oscillator leakage on the data can be ignored.

S302: if the terminal supports the first capability, the terminal determines whether to report the DC location to the network device.

When the terminal supports the first capability, the terminal may directly determine whether to report the DC location to the network device, or may determine whether to report the DC location to the network device according to a message or information issued by the network device, and the following detailed descriptions are respectively provided in a first to a fourth manner.

In a first manner, if the terminal supports the first capability, the terminal determines not to report the DC location to the network device. For example, the terminal may send a first message to the network device, where the first message is used to indicate that the terminal supports the first capability, and the terminal may directly determine not to report the DC location to the network device. Or when the network device receives a first message for indicating that the terminal supports the first capability, the network device does not send the first indication message to the terminal device, and the first indication message is used for indicating the terminal to report the DC position to the network; or the terminal device does not expect to receive the first indication message for indicating that the terminal reports the DC location to the network. Then, before the terminal sends uplink data to the network device, the terminal may send the uplink data to the network device after performing optimization processing on local oscillator leakage through a first capability (i.e., a local oscillator leakage self-calibration capability).

Optionally, if the terminal supports the first capability, the terminal may directly perform optimization processing on uplink data that needs to be sent through the first capability after sending, to the network device, a first message used for indicating that the terminal supports the first capability, without performing S302, that is, the terminal does not perform the step of determining whether to report the DC location to the network device.

Second, if the terminal supports the first capability and the terminal receives a second message indicating a calibration gap configured for the terminal by the network device, the terminal may determine not to report the DC location to the network device. Illustratively, the terminal sends a first message to the network device, the first message being used to indicate that the terminal supports the first capability; when the network equipment receives the first message, the network equipment sends a second message to the terminal, wherein the second message is used for indicating the calibration interval configured for the terminal by the network equipment; when the terminal receives the second message, the terminal may determine not to report the DC location to the network device. Or, after the network device sends the second message to the terminal, the network device does not send a first indication message to the terminal, where the first indication message is used to indicate the terminal device to report the DC location to the network. Then, before the terminal sends the uplink data to the network device, the terminal may perform optimization processing on the uplink data through a first capability (i.e., local oscillator leakage self-calibration capability) within the calibration interval, and then send the uplink data to the network device.

Optionally, if the terminal supports the first capability, the terminal may directly perform optimization processing on uplink data that needs to be sent through the first capability after sending, to the network device, a first message used for indicating that the terminal supports the first capability and receiving, from the network device, a second message used for indicating that the network device configures a calibration interval for the terminal, without performing S302, that is, the terminal does not perform the step of determining whether to report the DC location to the network device.

In a third manner, if the terminal supports the first capability and does not receive the second message indicating that the network device is configured for the calibration interval of the terminal, the terminal may determine to report the DC location to the network device. Illustratively, the terminal sends a first message to the network device, where the first message is used to indicate that the terminal supports the first capability; if the terminal does not receive the second message for indicating the network device to configure the calibration interval for the terminal within the preset time length, the terminal may determine to report the DC location to the network device. And then, the terminal can report the DC position to the network equipment, so that the network equipment can perform optimization processing on the uplink data sent by the terminal after receiving the DC position reported by the terminal.

Optionally, if the terminal supports the first capability, the terminal may directly report the DC location to the network device after sending the first message indicating that the terminal supports the first capability to the network device and receiving no second message indicating that the network device configures the calibration interval for the terminal within the preset time period, without performing S302, that is, the terminal does not perform the step of determining whether to report the DC location to the network device.

In a fourth manner, if the terminal supports the first capability, after receiving a second indication message from the network device, the terminal may be configured to indicate that the terminal reports the DC location or does not report the DC location, and determine whether to report the DC location to the network device according to the second indication message. Illustratively, the terminal sends a first message to the network device, the first message being used to indicate that the terminal supports the first capability; the terminal receives a second indication message from the network equipment; if the second indication is used for indicating the terminal to report the DC position, the terminal determines to report the DC position to the network equipment, and if the second indication message is used for indicating the terminal not to report the DC position, the terminal determines not to report the DC position to the network equipment.

Optionally, if the terminal supports the first capability, the terminal may send a first message for indicating that the terminal supports the first capability to the network device, and after receiving a second indication message from the network device, the terminal may report the DC location to the network device or not according to the second indication message, without performing S302, that is, the terminal does not perform the step of determining whether to report the DC location to the network device.

Further, the method may further include S302a: if the first message received by the network device is used for indicating that the terminal supports the first capability, namely the terminal supports the self-calibration capability of local oscillator leakage, the network device determines whether to send a second indication message for indicating that the terminal reports the DC position to the terminal device.

Specifically, if the first message received by the network device is used to indicate that the terminal supports the self-calibration capability of local oscillator leakage, the network device determines not to send a second indication message to the terminal device, where the second indication message is used to indicate that the terminal reports the DC location. Illustratively, the first message received by the network device is used to indicate that the terminal supports the first capability, and the network device may directly determine not to send the second indication message to the terminal device. Or, if the first message received by the network device is used to indicate that the terminal supports the self-calibration capability of the local oscillator leakage, and the network device sends a second message used to indicate a calibration gap (calibration gap) to the terminal, the network device determines not to send a second indication message used to indicate that the terminal reports the DC location to the terminal device. Or, if the first message received by the network device is used to indicate that the terminal supports the self-calibration capability of local oscillator leakage, and the network device does not send a second message used to indicate a calibration gap to the terminal, the network device determines to send a second indication message used to indicate that the terminal reports the DC location to the terminal.

S303: and if the terminal does not support the first capability, the terminal determines to report the DC position to the network equipment.

For example, if the terminal does not support the first capability, after the terminal sends a first message indicating that the terminal does not support the first capability to the network device, the terminal may directly determine to report the DC location to the network device.

Further, after S302 or S303, if the terminal supports the first capability and determines not to report the DC location to the network device, before the terminal can send the uplink data to the network device, the terminal performs optimization processing on the uplink data through the first capability (that is, the local oscillation leakage self-calibration capability), and then sends the uplink data to the network device. If the terminal determines to report the DC location to the network device, the terminal may report the DC location to the network device according to an indication of the network device or a capability of reporting the DC location supported by the terminal. Accordingly, as shown in fig. 8, the method may further include: S304-S305; and/or S306-S307.

S304: and the terminal sends a third message to the network equipment, wherein the third message is used for indicating whether the terminal supports the second capability. The second capability is the capability of supporting the enhanced DC location reporting of a single carrier or an aggregated carrier, and the enhanced DC location reporting supporting the single carrier and the enhanced DC location reporting supporting the aggregated carrier may be carried in the same reporting information or may be carried in different reporting information. Accordingly, the network device receives the third message.

The capability of the terminal to support enhanced DC location reporting of a single carrier may refer to: the terminal may report the DC location according to the scheme described in fig. 9 provided below, and the terminal may report the DC location to the network device using the MAC CE or the physical layer channel.

In addition, the capability of the terminal to support enhanced DC location reporting of aggregated carriers may refer to: the terminal may report the DC position corresponding to any two BWPs in a CC pair consisting of any two CCs in the multiple CCs aggregating the carrier to the network device according to a DC position reporting mode of intra-band carrier aggregation or a DC position reporting mode of inter-band carrier aggregation. For example, the terminal may perform DC location reporting according to the scheme described in fig. 2 above or fig. 9 below.

The terminal supporting the second capability may refer to that the terminal is capable of reporting the DC location to the network device according to the DC location reporting mode of the single carrier and the DC location reporting mode of the aggregated carrier. The terminal supporting the second capability may mean that the terminal cannot report the DC location to the network device according to the single carrier DC location reporting mode and the aggregated carrier DC location reporting mode.

Specifically, when the terminal supports the enhanced DC location reporting of the single carrier and the enhanced DC location reporting of the aggregated carrier, the third message sent by the terminal to the network device may be used to indicate that the terminal supports the second capability; when the terminal does not support enhanced DC location reporting of single carrier and enhanced DC location reporting of aggregated carrier, the third message sent by the terminal to the network device may be used to indicate that the terminal does not support the second capability.

S305: and when the terminal determines to report the DC position to the network equipment, the terminal sends a fourth message to the network equipment, wherein the fourth message is used for indicating the DC position of the terminal. Accordingly, the network device may receive the fourth message.

In an example, if the terminal does not support the second capability, the terminal may report the DC location of the terminal to the network device according to a DC location reporting manner of a single carrier. Wherein the reported DC position may include a DC position of each BWP in the multiple BWPs for the single carrier.

In another example, if the terminal is in aggregated carrier communication and the terminal supports the second capability, the terminal may report the DC location of the terminal to the network device in an enhanced single carrier and aggregated carrier DC location reporting manner. The DC position includes a DC position corresponding to any two BWPs in a CC pair composed of any two CCs among the multiple CCs aggregating the carrier, and any two BWPs are located in different CCs in the CC pair respectively. For example, the terminal may report the DC position of each channel when N CCs correspond to M channels of the terminal to the network device according to the method provided in fig. 2.

S306: and the terminal sends a fifth message to the network equipment, wherein the fifth message is used for indicating whether the terminal supports a third capability, and the third capability is the capability of supporting the reporting of the DC position of the in-band aggregation carrier. Accordingly, the network device may receive the fifth message.

The capability of the terminal supporting reporting of the DC position of the in-band aggregation carrier may be: the terminal may report the DC position corresponding to any two BWPs in a CC pair consisting of two CCs aggregating carriers to the network device according to a DC position reporting mode of in-band carrier aggregation. The terminal not supporting the third capability may mean that the terminal cannot report the DC location in the above manner.

Specifically, when the terminal supports the DC location report of the intra-band carrier aggregation, a fifth message sent by the terminal to the network device is used to indicate that the terminal supports the third capability; when the terminal does not support the DC location reporting of the in-band carrier aggregation, a fifth message sent by the terminal to the network device is used to indicate that the terminal does not support the third capability.

S307: and when the terminal determines to report the DC position to the network equipment, the terminal sends a sixth message to the network equipment, wherein the sixth message is used for indicating the DC position of the terminal. Accordingly, the network device may receive the sixth message.

In an example, if the terminal supports the third capability, the terminal may report the DC location of the terminal to the network device according to a DC location reporting manner of intra-band uplink carrier aggregation (intra-band UL CA), where a specific reporting manner may be described in a related protocol. For example, the aggregated carrier includes two CCs, the reported DC position includes DC positions corresponding to any two BWPs in the two CCs, and any two BWPs are located in different CCs in the two CCs, respectively.

Further, when the terminal supports the DC location reporting modes with different capabilities at the same time, after the terminal reports the capabilities supported by the terminal to the network device, the network device may send a third indication message to the terminal, where the third indication message is used to indicate a mode in which the terminal reports the DC location, so that when the terminal receives the third indication message, the terminal may report the DC location in the mode indicated by the third indication message.

For example, when the terminal supports the second capability, the third indication message sent by the network device may be used to indicate that the terminal reports in a manner of reporting the DC location of the single carrier, or reports in a manner of reporting the DC location of the aggregated carrier, or reports in a manner of reporting the DC location of the single carrier and in a manner of reporting the DC location of the aggregated carrier at the same time; when the terminal supports the third capability, the third indication message sent by the network device may be used to indicate that the terminal reports according to the in-band carrier aggregation DC location reporting mode. Correspondingly, the terminal may report the DC location of the terminal correspondingly according to the manner indicated by the third indication message sent by the network device.

In the method provided by the embodiment of the application, when the terminal supports the local oscillator leakage self-calibration capability and/or supports reporting of the DC position with different capabilities, the terminal may correspondingly determine whether to report the DC position to the network device according to the capability supported by the terminal or an indication of the network device, and complete reporting of the DC position according to a corresponding reporting mode when determining to report the DC position, thereby solving the problem of how to coexist in the network when the terminal supports the local oscillator leakage self-calibration capability and/or supports reporting of the DC position.

Fig. 9 is a flowchart of another message processing method according to an embodiment of the present application, where the method may be applied to the communication system 100 shown in fig. 1 to solve a problem that there is an offset between a DC location reported by a terminal and a DC location actually communicated, and the method may include the following steps.

S401: the terminal sends an update message to the network device, the update message for updating the DC location of the terminal.

Before the terminal and the network device perform data transmission, the terminal reports all possible DC positions of the terminal to the network device, after the network device establishes a communication link with the terminal and receives uplink data from the terminal, the network device can acquire a current communication DC position from the DC positions reported by the terminal, and perform data optimization processing on the uplink data of the terminal based on the current communication DC position.

During the data transmission between the terminal and the network device, although the configured CC and BWP corresponding to the terminal and the activated CC and BWP are not switched, the DC position of the terminal may be shifted, for example, the DC position of the terminal may be shifted due to a change in the temperature of the terminal or the operating environment or the transmission schedule, and the DC position reported by the terminal received by the network device is not changed, so that there may be a shift between the DC position of the current communication determined by the network device and the DC position of the actual communication of the terminal.

Based on this, when the DC of the terminal is offset, the terminal may report an updated DC location message through User Equipment (UE) assisted information (UE association information, UAI), where the updated DC location message is used to update the DC location reported by the terminal to the network device, and for example, the update message may be an RRC message.

It should be noted that the update message may be used to update one or more DC positions in the multiple DC positions reported by the terminal, where one DC position corresponds to a current communication local oscillator leakage position, where the multiple DC positions refer to DC positions based on each CC pair corresponding to multiple configured CCs and all corresponding BWP combinations, or DC positions based on each CC pair corresponding to multiple activated CCs and all corresponding configured BWP combinations. The updating manner of each DC location in the update message may be the same as the reporting manner of the DC location first reported by the terminal, and this is not specifically limited in this embodiment of the present application.

Optionally, when the terminal reports the DC location in a single carrier or inter-band aggregated carrier CA manner, the update message may be used to update one or more of the following information: an identification of a cell where the activated CC is located (activated CC serving cell ID), an identification of the activated BWP (activated BWP-ID), and a location of the resource element where the DC location is located (the specific range of the location may be 0-3301). Alternatively, the update message may be used to update one or more of the following: the identifier of the cell where the activated CC is located (activated CC serving cell ID), the identifier of the activated BWP (activated BWP-ID), and the offset of the DC position compared with the information reported by the previous DC position may be expressed by the number of REs.

Alternatively, when reporting the DC location by means of the in-band aggregated carrier CA, the update message may be used to update one or more of the following information: the corresponding relationship between the channel and the currently configured or activated CC; for each channel, the current activated CC list corresponding to the channel; for each channel, the channel corresponds to the currently activated BWP list; the DC position is the position of the resource particle (the position may be in the specific range of 0-3301). Alternatively, the update message may be used to update one or more of the following: the identifier of the cell where the activated CC is located (activated CC serving cell ID), the identifier of the activated BWP (activated BWP-ID), and the offset of the DC position compared with the information reported by the previous DC position may be represented by the RE number.

The channels may be divided according to PAs in the terminal, or may be divided according to the interval level of the terminal.

As an example, the terminal may update its DC location in an update message according to an agreed structure. For example, the following shows a structural schematic of an update message.

For intra-band CA combinations, the structure provides an updating method for reporting a corresponding DC position in the current communication. In another implementation, the terminal may also update DC positions of all possible BWP combinations on each CC pair corresponding to all configured CCs.

S402: the network device receives the update message. It should be noted that the update message is consistent with the update message in S401, and for the description of the update message, reference may be made to the related description in S401, which is not described herein again.

S403: and the network equipment determines the DC position of the current communication of the terminal according to the updating message.

When the network device receives the update message, the network device may re-determine the DC location of the current communication of the terminal according to the update message, so as to perform optimization processing on the received uplink data of the terminal based on the DC location of the current communication.

In the method provided by the embodiment of the application, when the DC position of the terminal deviates, the terminal may send an update message for updating the DC position to the network device, so that the network device may determine the DC position of the current communication according to the update message, and perform optimization processing on data based on the DC position of the current communication, thereby solving the problem that the DC position reported by the terminal deviates from the DC position of the actual communication, and avoiding the problem that the data performance is poor due to the optimization processing on data in an incorrect position by the network device.
