Description

Message processing method and device

The present application claims priority from the chinese patent application entitled "a message processing method and apparatus" filed by the national intellectual property office at 15/05/2020, application number 202010415410.8, the entire contents of which are incorporated herein by reference.

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 communication technology (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 the BWP to a network device, so that the network device optimizes data transmission between the BWP and the terminal according to the DC location.

It should be noted that, when the network device configures multiple cells for the terminal and each cell carrier includes multiple BWPs, the terminal may report the DC position corresponding to each BWP in each cell carrier to the network device respectively. So that during communication the network device can optimize the corresponding data transmission according to the DC position corresponding to the active BWP.

It should be understood that when multiple BWPs are activated simultaneously, such as in a Carrier Aggregation (CA) communication scenario, the CA communication corresponds to only one DC location, which can be used for targeted data optimization for the CA communication. However, the network device can only know the DC position of each BWP, so the network device cannot determine the DC position of the corresponding CA communication when multiple BWPs are activated simultaneously, and cannot optimize the data transmission of the CA communication accordingly.

Disclosure of Invention

Embodiments of the present application provide a message processing method and device, which enable a network device to unambiguously determine a DC location of a corresponding communication when multiple BWPs are simultaneously activated.

In order to achieve the above purpose, the embodiment of the present application adopts the following technical solutions:

in a first aspect, a method for processing a message is provided, where the method includes: a network device receives a first message, wherein the first message comprises a DC position of each bandwidth group (BWP) in M BWPs configured for a terminal by the network device; the network device determines a DC position of a current communication according to DC positions of activated N BWPs of the M BWPs, where M is an integer greater than or equal to 2 and N is an integer greater than or equal to 2 and less than M.

Based on this scheme, the network device can determine the DC position of the current communication according to the DC position corresponding to the activated BWP among the DC positions corresponding to the different BWPs in the first message, thereby providing an implementable method for the network device to determine the DC position of the corresponding communication when multiple BWPs are simultaneously activated. And then the network equipment can determine the local oscillator leakage position of the current communication so as to carry out targeted processing on the local oscillator leakage position, and the quality of the whole data transmission is improved.

In one possible design, the network device determining the DC position of the current communication according to the DC positions of the activated N BWPs of the M BWPs includes: the network device determines the DC position of the current communication according to a first frequency corresponding to the DC position of a first BWP and a second frequency corresponding to the DC position of a second BWP, where the DC position of the current communication corresponds to a center frequency of the first frequency and the second frequency, the first BWP corresponds to the BWP with the lowest DC position among the N BWPs, and the second BWP corresponds to the BWP with the highest DC position among the N BWPs. Based on this scheme, a specific implementation method is provided for a network device to determine the DC location of corresponding communications when multiple BWPs are activated. For example, the network device may use the center frequency of the DC location corresponding to the highest frequency BWP and the lowest frequency BWP among the activated BWPs as the frequency corresponding to the DC location of the current communication. It should be noted that in other embodiments of the present application, the network device may also determine the DC location of the current communication by other methods. For example, the network device may take the average of the frequencies corresponding to the multiple DC locations according to the DC location of all activated BWPs as the frequency corresponding to the DC location of the current communication. As another example, the network device may set different weights for all activated BWPs, where the weights may be set according to data transmission priorities or data transmission amounts on different BWPs, or may be flexibly set according to other requirements. The network device may comprehensively determine the DC location of the current communication according to the weights corresponding to the activated BWPs and the DC locations corresponding to the activated BWPs.

In one possible design, the center frequency of the DC position corresponding frequency of any two BWPs in the M BWPs is the Resource Element (RE) position corresponding frequency. Based on the scheme, the DC position of the current communication determined by the network equipment is made to be an available position. In the embodiment of the present application, for the method for determining the DC position of the corresponding communication when the multiple BWPs are simultaneously activated, the DC position of the corresponding communication may be limited to the frequency corresponding to the RE position.

In one possible design, the method further includes: and the network equipment sends a reporting indication message to the terminal, and the reporting indication message is used for indicating the DC position corresponding to the BWP distributed to the terminal. Based on the scheme, the network equipment can actively manage the operation of the terminal on the reported DC position through the reporting indication message.

In a second aspect, a message processing method is provided, where the method includes: the terminal sends a report message, where the report message includes a DC position of each bandwidth group (BWP) in M BWPs configured for the terminal by the network device, a center frequency of a frequency corresponding to the DC positions of any two BWPs in the M BWPs is a frequency corresponding to a Resource Element (RE) position, and M is an integer greater than or equal to 2.

Based on this scheme, the terminal can process all configured BWP correspondence messages to the network device. Wherein the center frequency of the corresponding DC position of any possible BWP that are activated two by two at the same time is RE position to ensure that the DC position of the corresponding communication is available. It should be noted that the second aspect provides a method in which the DC locations of any two BWPs correspond to the center frequency, and the center frequency of the DC location of the two BWPs to be activated by the network device is taken as the DC location corresponding to communication. In other embodiments of the present application, when the network device may take an average value of frequencies corresponding to the multiple DC positions according to the DC positions of all activated BWPs, and use the average value as a frequency corresponding to the DC position of the current communication, the terminal needs to consider and ensure that the DC position of the communication determined based on the method is an available DC position when allocating the DC position to different BWPs. Similarly, in other embodiments of the present application, when the network device may set different weights for all activated BWPs, the weights may be set according to data transmission priorities or data transmission amounts on different BWPs, or may be flexibly set according to other requirements. The network device may determine the DC position of the current communication by comprehensive judgment according to the weights corresponding to the activated BWPs and the DC positions corresponding to the activated BWPs, and when the terminal allocates the DC positions to different BWPs, it needs to consider and ensure that the DC position of the communication determined by the method is an available DC position.

In one possible design, the method further includes: and the terminal receives a reporting indication message, wherein the reporting indication message is used for indicating the terminal to report the DC position of each BWP in M BWPs configured for the terminal by the network equipment. Based on the scheme, the terminal may report the DC location of each BWP under the instruction of the network device. It should be noted that, in other embodiments of the present application, the reporting of the DC position by the terminal may also be actively reported, for example, reporting according to a certain period, and for example, reporting after configuring a corresponding DC position for each BWP configured by the network device.

In a third aspect, a message processing method is provided, where the method includes: the method comprises the steps that a network device receives a first message, wherein the first message comprises P DC positions, each DC position in the P DC positions is a DC position corresponding to any two bandwidth groups (BWPs) in M BWPs configured for a terminal by the network device, P is an integer larger than or equal to 1, and M is an integer larger than or equal to 2; the network device determines a DC location of the current communication from the first message.

Based on this scheme, a faster method is provided for a network device to determine the DC location of corresponding communications when multiple BWPs are simultaneously activated. For example, the network device may receive the DC position of the communication corresponding to the pairwise combination of all BWPs that may be activated simultaneously reported by the terminal, and determine the DC position of the current communication according to the DC position. It should be noted that, in the embodiment of the present application, the first message received by the network device may include the DC location of communication corresponding to the pairwise combination of BWPs configured for the terminal by all network devices. In other embodiments, only a portion of the DC locations of the communication corresponding to pairwise combinations of BWPs may be included in the first message. The possibility for pairwise combinations of BWPs included in the first message may be determined by the network environment in which the communication is currently located. For example, when the network environment in which the current communication is located allows two or more BWPs to be activated simultaneously in the same cell, the first message may include DC locations of any two corresponding communications in the BWPs configured for the terminal by all network devices. For another example, when the network environment in which the current communication is located only allows 1 BWP to be simultaneously activated in the same cell, the first message does not need to include the DC location of the communication corresponding to two BWPs in the same cell. Of course, in some embodiments, the requirement of the network environment where the current communication is located may also be disregarded, and the DC location of the corresponding communication when any two BWPs configured for the terminal by the network device are activated is uniformly reported, so as to ensure that the first message can cover all possible scenarios in which multiple BWPs are activated simultaneously.

In one possible design, P is less than or equal to

Is an integer of (1). Based on this scheme, the number of DC positions in the first message is specified, that is, the first message may include DC positions of corresponding communication when all possible two BWPs are activated simultaneously in BWPs configured for the terminal by all network devices. It is understood that in other implementations of the present application, the number of P may be adjusted appropriately if the requirements of the network environment in which the current communication is located are taken into account. For example, when only 1 BWP can be activated in a cell at the same time in the current network environment of the communication site, P may be

And Q is the number of cells configured for the terminal by the network device, and S is the number of BWPs in each cell.

In one possible design, any one of the P DC locations is a Resource Element (RE) location. Based on the scheme, the DC position of the current communication determined by the network equipment according to the first message can be ensured to be an available position.

In one possible design, the network device determining the DC location of the current communication from the first message includes: the network device determines a DC position corresponding to a first BWP and a second BWP, of N activated BWPs in the M BWPs, as a DC position of a current communication, where the DC position corresponding to the first BWP and the second BWP is one of the P DC positions, the first BWP is a BWP with a lowest frequency position in the N BWPs, and the second BWP is a BWP with a highest frequency position in the N BWPs, where N is an integer greater than or equal to 2 and less than M. Based on this scheme, the network device may determine the DC position of the corresponding current communication from the first message according to the BWP with the highest frequency and the BWP with the lowest frequency among the BWPs activated in the current communication.

In one possible design, the first message further includes: and is used for indicating the cell identity of the cell (cell) in which each DC position is located in the P DC positions. Based on this scheme, the first message may further include a cell identity of the DC location of each possible communication, so that the network device can more clearly determine the DC location of the corresponding current communication.

In one possible design, the method further includes: the network device sends a second message, where the second message is used to instruct the terminal to report a DC location corresponding to any two BWPs configured for the terminal by the network device. Based on this scheme, the network device may actively send a second message to the terminal to instruct the terminal to send a DC location where a corresponding plurality of BWPs that may be present are simultaneously activated for a corresponding communication.

In one possible design, the first message further includes: and the network equipment configures the DC position corresponding to each BWP in M BWPs for the terminal. Based on this scheme, the network device may also determine, from the first message, a DC location of the corresponding current communication when only one BWP is activated.

In a fourth aspect, a message processing method is provided, where the method includes: the terminal sends a first message, where the first message includes P DC positions, where each DC position in the P DC positions is a DC position corresponding to any two bandwidth groups (BWPs) in M BWPs configured for the terminal by the network device, P is an integer greater than or equal to 1, and M is an integer greater than or equal to 2.

Based on this scheme, a faster method is provided for a network device to determine the DC location of corresponding communications when multiple BWPs are simultaneously activated. For example, the terminal may report the DC location of the communication corresponding to the pairwise combination of all BWPs that may be activated simultaneously to the network device, so that the network device may determine the DC location of the current communication according to the DC location. It should be noted that, in the embodiment of the present application, the DC position of the communication corresponding to the pairwise combination of BWPs configured for the terminal by all the network devices may be included in the first message. In other embodiments, the first message may include only the DC position of the communication corresponding to a portion of the BWP in pairwise combination. The possibility for pairwise combinations of BWPs included in the first message may be determined by the network environment in which the communication is currently located. For example, when the current network environment in which the communication is located allows two or more BWPs to be activated simultaneously in the same cell, the first message may include DC locations of any two corresponding communications in the BWPs configured for the terminal by all network devices. For another example, when the network environment in which the current communication is located only allows 1 BWP to be simultaneously activated in the same cell, the first message does not need to include the DC location of the communication corresponding to two BWPs in the same cell. Of course, in some embodiments, the requirement of the network environment where the current communication is located may also be disregarded, and the DC location of the corresponding communication when any two BWPs configured for the terminal by the network device are activated is uniformly reported, so as to ensure that the first message can cover all possible scenarios in which multiple BWPs are activated simultaneously.

In one possible design, P is less than or equal to

Is an integer of (1). Based on this scheme, the number of DC positions in the first message is specified, i.e. the first message may comprise all network settingsIn the BWPs configured for the terminal, all possible two BWPs are activated simultaneously corresponding to the DC location of the communication. It is understood that in other implementations of the present application, the number of P may be adjusted appropriately if the requirements of the network environment in which the current communication is located are taken into account. For example, when only 1 BWP can be activated in a cell at the same time in the current network environment of the communication site, P may be

In one possible design, the first message further includes: and is used for indicating the cell identity of the cell (cell) in which each DC position is located in the P DC positions. Based on this scheme, the terminal may also report the cell identity of the DC location of each possible communication in the first message, so that the network device can more clearly determine the DC location of the corresponding current communication.

In one possible design, the method further includes: the terminal receives a second message, where the second message is used to instruct the terminal to report a DC location corresponding to any two BWPs configured for the terminal by the network device. Based on this scheme, the terminal may send the DC location of the corresponding communication to the network device according to an indication of the network device, such as a second message, that the corresponding BWPs that may occur are simultaneously activated. In other possible implementations, the terminal may also report the first message according to its own condition, for example, according to a certain period. In another example, reporting is performed after the DC locations of all possible communications are determined.

In one possible design, the first message further includes: and the network device configures a DC position corresponding to each BWP in M BWPs for the terminal. Based on the scheme, the terminal may also report the DC location corresponding to each BWP to the network device, so that the network device may also determine, according to the first message, the corresponding DC location of the current communication when only one BWP is activated.

In a fifth aspect, a message processing method is provided, where the method includes: the network device receives a first message, where the first message is used to indicate P direct current DC positions, where each DC position in the P DC positions is a DC position corresponding to any two bandwidth groups (BWPs) in a CC pair (pair) formed by any two CCs, and any two BWPs are located in different CCs in the CC pair, where P is an integer greater than or equal to 1, and a is an integer greater than 2. The network device determines a DC location of the current communication from the first message.

Based on this scheme, the network device may determine the DC location of the current communication according to the first message transmitted by the terminal. In this example, when the network device configures three or more CCs for the terminal, the first message may include a DC location in case all BWPs in CCs transmitted by the terminal are activated two by two, which may be activated simultaneously. The reporting of the first message may be performed in units of CCs. For example, the network device configures 3 CCs, such as CC1, CC2, and CC3, for the terminal. Then, the first message may include CC1 and CC2 to form a CC pair, any BWP from CC1, and any BWP from CC2 to form a BWP pair combination, where the BWP pair combination may correspond to a DC position. Similarly, the first message may further include DC positions corresponding to two-by-two combinations of other possible BWPs in the CC pair consisting of CC1 and CC 2. In some implementations, the DC positions corresponding to a CC pair of CC1 and CC2 may include all possible cases of two-by-two combined DC positions of one BWP in CC1 and one BWP in CC 2. Similarly, all possible DC positions in the CC pair of CC1 and CC3 may also be included in the first message. All possible DC positions in the CC pair of CC2 and CC3 may also be included in the first message. In this way, the network device can know from the first message the possible DC location when any CC pair is activated, based on all CCs currently configured for the terminal. When the DC location of the current communication needs to be determined, the network device may determine, according to the first message, the DC location of the activated corresponding CC pair. In some implementations, the DC location of the current communication can be one of P DC locations. In other implementations, the DC location of the current communication may also be determined by one or more of the P DC locations.

In one possible design, of the at least two currently activated CCs, a first CC with a lowest carrier frequency point and a second CC with a highest carrier frequency point form a first CC pair, and in the first CC pair, the BWP currently in an activated state forms a first BWP combination. The network device determines the DC location of the current communication according to the first message, including: and the network device inquires and acquires a DC position corresponding to the first BWP combination in the first CC pair from the P DC positions as a DC position of current communication. Based on this scheme, a scheme is provided for a network device to determine the DC location of a current communication. In this example, if there are 2 CCs activated at the same time, the network device may look down the CC pair consisting of the two activated CCs in the first message. The network device may also search, according to pairwise combinations of BWPs respectively activated in the currently activated 2 CCs, pairwise combinations of BWPs corresponding to the pairwise combinations of activated BWPs under the corresponding CC pair in the first message. And thus the corresponding DC position. In this embodiment, taking the DC position corresponding to the BWPs formed by the BWPs activated in the currently activated CC pair combined in pairs in the first message as the current DC position as an example, in other implementations, after determining the corresponding DC position in the first message, the network device may further determine, according to the actual situation, the DC position of the current communication according to the DC position. That is, the DC position of the current communication may be the same DC position as the corresponding DC position in the first message, or may be different. Similarly, when the network device determines that 3 or more CCs are simultaneously activated, the network device may use, as a CC pair corresponding to the current communication, a CC with the highest carrier frequency point and a CC with the lowest carrier frequency point in the simultaneously activated CCs, thereby determining the DC position of the current communication by using a scheme similar to the scheme when 2 CCs are simultaneously activated. It should be noted that, in other implementation manners of the present application, the network device may also flexibly adjust the CC pair corresponding to the current communication according to a specific situation, such as a specific configuration condition of the network. That is, according to the specific configuration condition of the network, the CC pair for determining the DC position of the current communication may not be composed of the CC with the highest carrier frequency point and the CC with the lowest carrier frequency point, but may be determined according to the specific configuration condition of the network. After the CC pair corresponding to the current communication is determined, the DC position of the current communication may be determined according to the above scheme.

In one possible design, any one of the P DC locations is a resource element RE location. Based on the scheme, the DC position of the current communication determined by the network equipment according to the first message can be ensured to be an available position.

In one possible design, the first message further includes: and the cell identifier is used for indicating the cell in which each DC position is located in the P DC positions. Based on this scheme, the terminal may also report the cell identity of the DC location of each possible communication in the first message, so that the network device can more clearly determine the DC location of the corresponding current communication.

In one possible design, the method further includes: and the network equipment sends a second message, wherein the second message is used for indicating the terminal to send the first message. In other implementations of the present application, the second message may be used to instruct the terminal to transmit P DC locations. Alternatively, the terminal is instructed to transmit the P DC positions by other means. Based on the scheme, the network device may actively send the second message to the terminal to instruct the terminal to send the corresponding first message. For example, the first message may include the above P DC positions and information corresponding to the P DC positions.

In a sixth aspect, a message processing method is provided, where the method includes: the terminal sends a first message, where the first message is used to indicate P direct current DC positions, where each DC position in the P DC positions is a DC position corresponding to any two bandwidth groups (BWPs) in a CC pair (pair) formed by any two CCs in a Component Carriers (CCs) configured by the network device for the terminal, where any two BWPs are located in different CCs in the CC pair, P is an integer greater than or equal to 1, and a is an integer greater than 2.

Based on the scheme, the terminal may transmit a first message to the network device, so that the network device may determine the DC location of the current communication according to the first message transmitted by the terminal. In this example, when the network device configures three or more CCs for the terminal, the first message may include a DC location in case all BWPs in CCs transmitted by the terminal are activated two by two, which may be activated simultaneously. The reporting of the first message may be performed in units of CCs. For example, the network device configures 3 CCs, such as CC1, CC2, and CC3, for the terminal. Then, the first message may include CC1 and CC2 to form a CC pair, any BWP from CC1, and any BWP from CC2 to form a BWP pair combination, where the BWP pair combination may correspond to a DC position. Similarly, the first message may further include DC positions corresponding to two-by-two combinations of other possible BWPs in the CC pair consisting of CC1 and CC 2. In some implementations, the DC positions corresponding to a CC pair of CC1 and CC2 may include all possible cases of two-by-two combined DC positions of one BWP in CC1 and one BWP in CC 2. Similarly, all possible DC positions in the CC pair of CC1 and CC3 may also be included in the first message. All possible DC positions in the CC pair consisting of CC2 and CC3 may also be included in the first message. In this way, through the first message sent by the terminal, the network device may be enabled to know from the first message the possible DC location when any CC pair is activated, based on all CCs currently configured for the terminal. So that when the DC location of the current communication needs to be determined, the network device can determine, according to the first message, the DC location of the corresponding CC pair when activated. In some implementations, the DC location of the current communication can be one of P DC locations. In other implementations, the DC location of the current communication may also be determined by one or more of the P DC locations.

In one possible design, any one of the P DC locations is a resource element RE location. Based on the scheme, the terminal can be ensured to be capable of enabling the DC position of the current communication determined by the network equipment according to the first message to be an available position after the first message is sent.

In one possible design, the method further includes: and the terminal receives a second message, wherein the second message is used for indicating the terminal to send the first message. Based on the scheme, a triggering mechanism of the first message transmission is provided.

Detailed Description

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

In a Long Term Evolution (LTE) system, a default DC position is generally located on a Resource Element (RE) at a center of a frequency domain of a corresponding cell carrier, that is, a frequency corresponding to the DC position corresponding to the cell is generally located on a center frequency point of a frequency domain bandwidth corresponding to the corresponding cell carrier. The network device may determine the DC position according to the frequency domain bandwidth corresponding to the cell carrier, and perform targeted processing 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 an lo leakage position of the corresponding cell carrier, so as to perform corresponding processing accordingly and improve data transmission quality.

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, the BWP on the cell carrier may be referred to as the BWP of the 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. Taking a network device as a terminal, 2 cells (e.g., cell 1 and cell 2) are configured, 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, DC position DC11 corresponding to BWP11, DC position DC12 corresponding to BWP12, DC position DC21 corresponding to BWP21, and 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 current communication lo leak based on the corresponding DC location and thus optimize the data transmission accordingly.

It should be understood that, in the data transmission of the 5G system, there are also a large number of scenarios in which multiple BWPs are activated simultaneously for data transmission. For example, in a CA communication scenario, such as intra-band CA (intra-band CA) communication or inter-band CA (inter-band CA) communication, in a plurality of cells configured by a network device for a terminal, there may be two or more cells each of which may have one activated BWP. As a whole transmission process, a CA communication process will correspond to only one lo leakage location, i.e. only one DC location. It is understood that, at present, the network device may know the DC location of each BWP according to the method in the above description, but when there are multiple BWPs activated simultaneously, the network device may not know the DC location of the corresponding communication, and thus the data transmission cannot be optimized accordingly.

In order to solve the foregoing problem, embodiments of the present application provide a message processing method, which enables a network device to know a DC location of a corresponding communication when multiple BWPs are activated simultaneously, and further enable active management of the communication according to the DC location, for example, corresponding processing is performed on a data block corresponding to the DC location.

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 embodiment of the present application does not limit the number of terminals included in the communication system 100. 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, a laptop, a handheld computer, a notebook, 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), a Virtual Reality (VR) device, and a media player, and the embodiment of the present application does not particularly limit a 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. For example, when the network device 120 is a 5G base station, a 5G New Radio (NR) can be provided for performing 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 comprise a plurality of components associated with signal transmission and reception (e.g., processors, modulators, multiplexers, encoders, demultiplexers, or antennas, etc.), as will be appreciated by one skilled 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 sends 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 indicates the DC position of the corresponding communication when any two BWPs, which are all possible BWPs configured for the terminal 110, are simultaneously activated, to the network device 120. 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.

The message processing method provided in the embodiment of the present application can be applied to the communication system 100 shown in fig. 1. The following describes a message processing method provided in an embodiment of the present application in detail with reference to the accompanying drawings. As shown in fig. 2, the message processing method may be used to determine the DC location currently used for communication. Illustratively, the method may include S201-S203.

S201, the terminal sends a message 1 to the network equipment.

Wherein the message 1 may include a DC location of each BWP of the M BWPs configured by the network device for the terminal. Wherein M is an integer greater than or equal to 2.

Illustratively, 3 cells, such as cell 1, cell 2, and cell3, are configured with the network device as the terminal. Each cell includes 4 BWPs, such as BWP11, BWP12, BWP13 and BWP14 in cell 1. cell 2 includes BWP21, BWP22, BWP23 and BWP24. cell3 includes BWP31, BWP32, BWP33 and BWP34 as examples.

It should be understood that the DC position of the different BWPs is self-configured by the terminal. For example, a terminal may configure DC11 for BWP11, DC12 for BWP12, DC13 for BWP13, DC21 for BWP21, DC22 for BWP22, DC23 for BWP23, DC31 for BWP31, DC32 for BWP32, and DC33 for BWP 33.

The terminal may report the DC location corresponding to each BWP to the network device through the message 1, so that the network device can know the DC location corresponding to each BWP. Illustratively, in some embodiments, the message 1 may be a Radio Resource Control (RRC) message. For example, the message 1 may be an rrcreeconfigurationcomplete message, or an rrcresumecomple message.

As an example, the terminal may transmit the DC location corresponding to each BWP in message 1 according to an agreed structure. In some implementations, when transmitting the DC position corresponding to each BWP, the terminal may transmit in units of cells corresponding to the BWP. For example, the following shows a structural schematic of a message 1.

UplinkTxdirectCurrentList{

Cell 1{

UplinkTxdirectCurrentBWP{

BWP1:DC1

BWP2:DC2

BWP3:DC3

BWP4:DC4

}

Cell 2{

BWP4:DC4

}

Cell 3{

UplinkTxdirectCurrentBWP{

BWP1:DC1

BWP2:DC2

BWP3:DC3

BWP4:DC4

}

It can be seen that the terminal may send, in the cell 1, DC1 (i.e., the above DC 11) corresponding to BWP1 (i.e., the above BWP 11), DC2 (i.e., the above DC 12) corresponding to BWP2 (i.e., the above BWP 21), and DC3 (i.e., the above DC 13) corresponding to BWP3 (i.e., the above BWP 31).

Generally, since 3300 Resource Elements (REs) may be included in each cell carrier, that is, each cell carrier may provide 3300 frequencies for data transmission. Therefore, in some implementations of the present application, a DC position (e.g., DC11, DC12, etc.) configured for BWP by any of the terminals may be identified by a value in the range of 0 to 3301 to correspond to the BWP. Where 0-3299 may be used to indicate the frequency corresponding to the corresponding DC location, 3300 may be used to indicate that the DC location is not within the cell carrier (i.e., out the carrier), and 3301 may be used to indicate that the DC location is unpredictable (i.e., an understated position with the carrier).

It should be noted that, in this embodiment of the present application, the message 1 may be actively reported by the terminal after receiving M BWPs configured for the terminal by the network device, or may be reported under an instruction of the network device. As an example, the network device may send a message 2 to the terminal, where the message 2 may be used to instruct the terminal to report a DC location corresponding to each BWP in the M BWPs configured for the terminal.

Illustratively, the message 2 may be an RRC message. In some embodiments, the message 2 may be a CellGroupConfig message, where a reportuplinktxdiretcurrent identifier included in the CellGroupConfig message may be used to indicate whether the terminal needs to report the content corresponding to the message 1 (i.e., the DC location corresponding to each BWP). For example, when the reportuplinktxdiretcurrent identifier is set to true, the terminal may report the content corresponding to the message 1 according to the message 2. Correspondingly, when the reportuplinktxdiretcurrent identifier is set to be null, the terminal does not need to report the content corresponding to the message 1. Of course, the message 2 may also implement the corresponding function through other RRC messages or non-RRC messages, which is not limited in this embodiment of the application.

S202, the network equipment receives the message 1.

And S203, the network equipment calculates and acquires the DC position of the current communication according to the message 1.

After receiving the message 1, the network device can explicitly know the DC location corresponding to different BWPs. When the network device is communicating with the terminal, the DC location of the corresponding communication may be determined based on the activated BWP.

For example, in some embodiments, when only one BWP of the configured multiple BWPs is activated when the network device is in communication with the terminal, the network device may determine the DC location corresponding to the activated BWP according to message 1.

In other embodiments, when multiple BWPs are simultaneously activated while the network device is communicating with the terminal, then the network device may also determine the DC location corresponding to the communication based on message 1. This method is explained in detail below.

In some implementations, the network device may determine the DC location of the current communication based on a first frequency corresponding to the DC location of the first BWP and a second frequency corresponding to the DC location of the second BWP. The DC position of the current communication corresponds to the center frequency of the first frequency and the second frequency, the first BWP corresponds to the BWP with the lowest frequency in the active BWPs, and the second BWP corresponds to the BWP with the highest frequency in the active BWPs.

The following illustrates the implementation of the above method with reference to an example. Wherein, 3 cells, such as cell 1, cell 2 and cell3, are configured continuously with the network device as the terminal. Each cell includes 4 BWPs, for example, cell 1 includes BWP11, BWP12, BWP13, and BWP14, cell 2 includes BWP21, BWP22, BWP23, and BWP24, and cell3 includes BWP31, BWP32, BWP33, and BWP24.

Referring to fig. 3 (a), the communication process is intra band CA communication, and the active BWPs include BWP11, BWP22, and BWP32.BWP11 corresponds to DC position DC11, BWP22 corresponds to DC position DC22, BWP32 corresponds to DC position DC32. The different DC positions are arranged in order DC11, DC22, DC32 according to the corresponding frequency from low to high as an example. The network device may choose the DC position corresponding to the lowest frequency BWP (e.g., BWP 11) and the DC position corresponding to the highest frequency BWP (e.g., BWP 32) according to the position of the DC position corresponding to the activated BWP on the frequency domain, for determining the DC position corresponding to the communication. As an example, the network device may determine, according to the DC location corresponding to BWP11 and the DC location corresponding to BWP32, a center frequency of frequencies corresponding to the two DC locations, and use the DC location with the center frequency as the DC location of the intra band CA communication. For example, as shown in fig. 3 (b), if the frequency of BWP11 corresponding to DC11 is f11, and the frequency of BWP32 corresponding to DC32 is f32, the network device may determine that the center frequencies of these two DC positions correspond to frequencies f0= (f 11+ f 32)/2, and use the RE position corresponding to f0 as the DC position of the intra band CA currently communicating.

It should be understood that, in the above example, the example is described by taking the case that 3 BWPs are simultaneously activated, in other embodiments, when the BWPs activated in the intra band CA communication are 2 or 4 or more BWPs, the method for determining the DC position corresponding to the intra band CA communication is similar, and will not be described herein again.

In addition, in other embodiments of the present application, the network device may also determine the DC position of the current communication according to the DC position corresponding to each BWP provided in message 1 in other manners. As an example, in some implementations, the network device may determine the DC location of the current communication from the DC location distribution corresponding to all activated BWPs. For example, the communication procedure is intra band CA communication as shown in (a) in fig. 3 as an example. The network device may set the frequency f0 corresponding to the DC location of the intra band CA communication to (f 11+ f22+ f 32)/3. In other implementations, the network device may set a different weight for each of the active BWPs based on the data traffic and determine the DC location of the communication based on the weight and the DC location of each of the active BWPs. Therefore, when the network equipment optimizes data transmission according to the DC position of communication, the network equipment can tilt to a frequency with larger data flow, and the optimization effect is further improved.

In the above example, the DC position determined by calculation is taken as the DC position of the current communication. In other embodiments of the present application, the network device may further use an RE near the RE position where the DC position is determined by calculation as the DC position of the current communication to be selected, so that the network device can determine the position of the local oscillator leakage of the current communication more accurately according to the DC position. For example, the network device may use 12 REs in a Resource Block (RB) where the DC position obtained by the calculation is located as the candidate DC position of the current communication. By measuring the interference situation at each RE of the 12 REs, the RE position with the largest interference is determined as the DC position corresponding to the current communication. The DC location of the current communication thus determined has the largest interference in the adjacent frequency domain, and therefore operating on this DC location specifically can better optimize the transmission of data. Of course, in order to reduce the data processing amount of the network device when determining the DC position, in other embodiments, the network device may further take two or more REs adjacent to the RE corresponding to the DC position obtained by calculation as candidate DC positions, and perform interference measurement on the candidate DC positions respectively, and take the RE with the largest interference as the DC position of the current communication.

Generally, the DC position corresponding to communication is within the frequency domain of the cell carrier configured by the network device for the terminal, that is, the frequency corresponding to the DC position is one of the frequencies corresponding to the RE positions in the cell carrier. Therefore, in this embodiment, when the terminal configures a DC position for each BWP configured by the network device, it will also ensure that the frequency corresponding to the corresponding DC position when any two BWPs are activated is an RE position. For example, when the terminal configures a DC position for each BWP, it needs to ensure that the center frequency of the DC position corresponding frequency of any two BWPs is the RE position corresponding frequency. So that the DC position determined by the scheme as shown in fig. 2 or fig. 3 is the available DC position.

Based on this scheme, the network device may determine, in cooperation with the terminal, a DC position of current communication when there are multiple BWPs activated, such as the intra band CA communication scenario in the above example, according to the DC position of each BWP. And then optimizing the current communication according to the DC position. In addition, based on the scheme, the DC position of the communication for simultaneously activating multiple BWPs is determined, which is helpful for testing and verifying the corresponding Radio Frequency (RF) performance of the terminal and/or the network device in the development process.

Please refer to fig. 4, which is a flowchart illustrating another message processing method according to an embodiment of the present application. By this method, the network device can acquire the DC location of the current communication more quickly. As shown in fig. 4, the method may include S401-S403.

S401, the terminal sends a message 3 to the network equipment.

Wherein the message 3 may include P DC positions. Each of the P DC positions is a DC position corresponding to any two BWPs of the M BWPs configured for the terminal by the network device. Wherein P is an integer greater than or equal to 1, and M is an integer greater than or equal to 2.

It should be understood that, in different communication scenarios, if there are multiple BWPs activated simultaneously, the BWPs activated simultaneously may be any BWPs of M BWPs configured for the terminal by the network device. Therefore, in this embodiment, in all cases where any two BWPs configured for the network device are activated as a group, the terminal may send the DC location of the corresponding communication to the network device, so that the network device may determine from this that there is any DC location of the activated communication of the BWPs. That is, in this example, P may be less than or equal to

Wherein, the specific value of P can be flexibly adjusted according to the protocol requirement corresponding to the network environment where the communication is located. For example, when two or more BWPs can be activated simultaneously in the same cell in the network environment where the communication is located, P is equal to

When only 1 BWP can be activated simultaneously in the same cell in the network environment of the communication, P is equal to

Wherein Q is the number of cells allocated by the network device for the terminal, and S is the number of BWPs included in each cell.

As an example, in some embodiments, two or more BWPs may be activated simultaneously in the same cell in the network environment in which the communication is located. 3 cells such as cell 1, cell 2 and cell3 are configured by taking network equipment as a terminal. Each cell includes 4 BWPs, for example, cell 1 includes BWP11, BWP12, BWP13, BWP14, cell 2 includes BWP21, BWP22, BWP23, BWP24, and cell3 includes BWP31, BWP32, BWP33, BWP 34. The terminal may configure corresponding DC positions for corresponding communications when any two of the 12 BWPs are activated, that is, two BWPs may correspond to the DC position of one communication. For example, when BWP11 is activated simultaneously with BWP21, the terminal may configure the DC position of DC11-21 for communication. As another example, when BWP12 is activated simultaneously with BWP21, the terminal may configure the DC position of DC12-21 for communication. Similarly, the terminal may configure the DC location for the corresponding communication when other pairwise BWPs are activated. It will be appreciated that, as shown in FIG. 5, in this example, the terminal may allocate a common communication for each of the 12 BWPs that corresponds to when a group is activated

A DC position. The terminal may send the 66 locations and information corresponding to BWP to the network device, carried in message 3.

In other embodiments, at most 1 BWP may be activated simultaneously in the same cell in the network in which the communication is located. The terminal may appropriately reduce the BWP combination carried in message 3 with the corresponding DC location information. For example, the network device configures Q cells for the terminal, and S BWPs are configured in each cell, that is, Q × S = M BWPs are configured for the terminal by the network device. The terminal may configure the corresponding communication for two-by-two combinations of different possible BWPs

A DC position, and this

This DC position is sent to the network device in message 3. Illustratively, 3 cells, such as cell 1, cell 2 and cell3, continue to be configured with the network device as the terminal. Each cell includes 4 BWPs, for example, BWP11, BWP12, BWP13, BWP14 in cell 1, BWP21, BWP22, BWP23, BWP24 in cell 2, BWP31, BWP32, BWP33, BWP34 in cell 3. The terminal may assign a DC position of DC11-21 for the corresponding communication when BWP11 and BWP21 are activated. The terminal may assign a DC position of DC11-22 for the corresponding communication when BWP11 and BWP22 are activated. The terminal may assign a DC position of DC11-23 for the corresponding communication when BWP11 and BWP23 are activated. Similarly, the terminal may also assign a corresponding DC position for other combinations of two BWPs that may be activated simultaneously. Thus, as shown in FIG. 6, the terminal may allocate a common communication for all combinations of two BWPs that may be activated simultaneously

A DC position. The terminal can send these 48 DC positions to the network device carried in message 3.

It should be understood that, in different network environments, the terminal may determine, according to different protocol rules, that BWPs that may occur are activated two by two at the same time for corresponding scenarios, and configure corresponding DC locations for different scenarios. Therefore, in addition to the two cases shown in fig. 5 and fig. 6, the terminal can flexibly adjust the number of DC positions of communication that can be allocated according to the case where BWPs defined by the corresponding protocol are simultaneously activated in the network environment corresponding to the communication. The embodiment of the present application is not described in detail herein.

In some implementations of embodiments of the present application, message 3 may be an RRC message. For example, the message 3 may be a rrcreeconfigurationcomplete message or a RRCResumeComplete message. In the message 3, the terminal may report the cell identifiers corresponding to the DC locations of different communications at the same time, so that the network device can know in which cell the DC location of the corresponding communication is located. Correspondingly, the terminal may report the frequencies corresponding to the DC positions of different communications in groups according to the carrier frequency band of the cell by using the cell as a unit. As an example, the following shows a structural schematic of a message 3 provided in the embodiment of the present application. For example, two communications corresponding to two activated BWPs (for example, BWP11 in cell 1 and BWP21 in cell 2 are simultaneously activated and are denoted as BWP11-21, and BWP11 in cell 1 and BWP22 in cell 2 are simultaneously activated and are denoted as BWP 11-22) by the terminal are allocated with 2 DC positions (for example, DC11-21 and DC 11-22), the frequency corresponding to DC11-21 falls in cell 1, and the frequency corresponding to DC11-22 falls in cell 2.

cell 1+cell 2{

BWP11-21

{cellID:{1}

Location:(DC11-21)

}

BWP11-22

{cellID:{2}

Location:(DC11-22)

}

It can be seen that, through the message 3, the network device can know that the terminal is in the frequency band range corresponding to the cell 1, and the DC position of the communication corresponding to the simultaneous activation of the two BWPs identified as BWPs 11-21 (i.e. BWP11 in cell 1 and BWP21 in cell 2) is DC11-21. Meanwhile, the network device may further know that the terminal is in the frequency band range corresponding to the cell 2, and the DC position of the communication corresponding to the simultaneous activation of the two BWPs identified as BWPs 11-22 (i.e., BWP11 in cell 1 and BWP22 in cell 2) is DC11-22. It will be appreciated that as one possible implementation, the DC location may be identified by a corresponding 0-3301.

It should be noted that, in the embodiment of the present application, the message 3 may be actively reported by the terminal after configuring the DC location for the communication corresponding to the possible BWPs that are activated pairwise, or may be reported under the instruction of the network device. As an example, the network device may send a message 4 to the terminal, where the message 4 may be used to indicate a DC location of a corresponding communication when every two BWPs that may occur are activated, among M BWPs reported by the terminal for configuration.

Illustratively, message 4 may also be an RRC message. For example, message 4 may be a CellGroupConfig message. In some implementation manners, a reportuplinktxdiretcurrentent identifier included in the CellGroupConfig message may be used to indicate whether the terminal needs to report the content corresponding to the message 3. For example, when the reportuplinktxdiretcurrent identifier is set to a first value, the terminal may report the content corresponding to the message 3 according to the message 4. When the reportuplinktxdiretcurrent identifier is set to the second value, the terminal does not need to report the content corresponding to the message 3.

Of course, the above description of message 3 and message 4 is merely exemplary. In the embodiment of the present application, the message 3 and/or the message 4 may also implement corresponding functions through other RRC messages or non-RRC messages. For example, unlike the reportuplinktxdiretcurrent identifier included in the current CellGroupConfig message, which is used to notify the UE to report the DC location corresponding to each BWP in each cell, a new identifier (for example, referred to as reportuplinktxdiretcurrent-multitbwp) may be set to notify the UE to report the corresponding content of the message 3. The embodiment of the present application does not limit this.

As an example, the network device may implement the sending of the message 4 in the following interactive manner.

The CA combination that needs to report the DC position according to the CC pair mode may be located in the master cell group MCG, or may be located in the secondary cell group SCG, and the network device may indicate that the UE needs to perform CA uplink transmission of the DC position in a certain cell group by attaching the message 4 to a different cell group. Specific implementations can be described as follows:

1> the contents of the RRC reconfiguration complete (rrcconfigurationcomplete) message are set as follows:

2> if RRCReconfiguration contains master cell group (masterCellGroup, MCG) of uplink transmit direct current CA report (reportuplink txdirect current CA):

3> the CC pairs under each MCG configured in the in-band continuous upstream CA comprise an upstream transmitting direct current CA list (uplinkTxDirectCurrentListCA);

2> if RRCReconfiguration contains a Secondary Cell Group (SCG) of a uplink transmit direct current CA report (reportuplink txdigital currentca):

3> the CC pairs under each SCG configured in the in-band continuous upstream CA comprise an upstream transmitting direct current CA list (uplinkTxDirectCurrentListCA);

in the protocol structure can be expressed as:

1>set the content of the RRCReconfigurationComplete message as follows:

2>if the RRCReconfiguration includes the masterCellGroup containing the reportUplinkTxDirectCurrentCA:

3>include the uplinkTxDirectCurrentListCA for each MCG serving cells pairs configured within intra-band contiguous UL CA；

2>if the RRCReconfiguration includes the secondaryCellGroup containing the reportUplinkTxDirectCurrentCA:

3>include the uplinkTxDirectCurrentListCA for each SCG serving cells pairs configured within intra-band contiguous UL CA；

through the implementation, when the network device configures the second message for the terminal device through the RRC configuration message, the UE sends the first message to the base station for indicating the DC location under CA.

Correspondingly, the terminal device may report the first message to the network device in the RRC reconfiguration complete message.

As an example, the structure in rrcreconconfigurationcomplete message may include:

namely:

in some implementations of the present application, related content may also be added in a cell group configuration information element (cellgroupconfiguration information element) and a corresponding cell group configuration field description (cellgroupconfiguration field descriptions), so that a second message may be sent to the terminal through an RRC configuration message, where the second message may include a DC location indication under CA. That is, the sending of the first message is enabled by the second message. Message 3 in this example corresponds to the first message in the above description and message 4 corresponds to the second message in the above description.

In the cell group configuration information element, it may include:

corresponding specifications may be included in the cell group configuration field description:

uplink transmit DC location CA reporting

Allowing reporting of direct current location information of upstream in-band CAs at BWP configuration and reconfiguration. This field is not present in the IE CellGroupConfig when provided as part of the RRCSetup message.

reportUplinkTxDirectCurrentCA

Enables reporting of uplink Direct Current location information for uplink intra-band CA upon BWP configuration and reconfiguration.This field is absent in the IE CellGroupConfig when provided as part of RRCSetup message.

In addition, it should be noted that, in the above example, the DC position of the communication configuration corresponding to when BWPs that may occur in message 3 are activated in pairs is taken as an example for explanation. In other embodiments, the terminal may also configure a corresponding DC position for each BWP, e.g., configure DC11 for BWP11, configure DC21 for BWP21, etc. In this example, the terminal may also carry the DC location corresponding to each BWP in message 3, and send the DC location to the network device, so that the network device may determine therefrom the DC location corresponding to the communication when only one BWP is activated. As a possible implementation manner, when the network device needs the terminal to report the DC location corresponding to each BWP, the network device may send a CellGroupConfig message including a reportuplinktxdiretcurrent identifier set to a third value to the terminal, so that the terminal may feed back the DC location corresponding to each BWP to the network device according to the received CellGroupConfig message. In other implementations, the network device may send a CellGroupConfig message including a reportuplinktxdiretcurrent identifier set to a fourth value to the terminal, so that the terminal feeds back, to the network device, a DC location corresponding to each BWP and a DC location of a communication configuration corresponding to when two BWPs that may occur are activated, according to the received CellGroupConfig message.

In conjunction with the above description, it can be understood that, after configuring DC locations for the corresponding communications when different two BWPs that may occur are simultaneously activated, the terminal may carry all configured DC locations in message 3 and send the messages to the network device, so that the network device can know the DC locations of the corresponding communications when all two BWPs that may occur are simultaneously activated.

S402, the network equipment receives the message 3.

And S403, the network equipment determines the DC position of the current communication according to the message 3.

The network device can know from the received message 3 the DC location of the corresponding communication when any two BWPs are simultaneously activated. For example, if only two activated BWPs are included in a communication procedure, the network device may determine the DC location of the current communication according to the DC location corresponding to the two activated BWPs in message 3. For another example, if a plurality of activated BWPs are included in a communication procedure, the network device may also determine the corresponding DC location from message 3 as the DC location of the current communication according to the highest BWP and the lowest BWP corresponding to the plurality of activated BWPs.

Illustratively, in some embodiments, the current communication is intra-band CA communication, a protocol corresponding to the intra-band CA communication specifies that only 1 BWP is activated in one cell at the same time, and the network device configures 3 cells, such as cell 1, cell 2, and cell3, for the terminal. Each cell includes 4 BWPs, for example, BWP11, BWP12, BWP13, BWP14 in cell 1, BWP21, BWP22, BWP23, BWP24 in cell 2, BWP31, BWP32, BWP33, BWP34 in cell 3. The message 3 received by the network device from the terminal may include the 48 DC locations as shown in fig. 6, and the corresponding two BWP information that are activated.

In some implementation scenarios, for example, BWP11 and BWP21 are activated simultaneously by the intra band CA. The network device may look up the DC locations (e.g., DC 11-21) corresponding to BWP11 and BWP21 in message 3 and treat DC11-21 as the DC location of the current intra band CA.

In other implementation scenarios, for example, BWP11, BWP21, and BWP31 are activated simultaneously by the intra band CA. Since there are cases where more than 2 BWPs are activated simultaneously, the network device may choose 2 BWPs from the activated BWPs and determine the DC location of the intra band CA accordingly. For example, the network device may select two BWPs with the lowest and highest frequencies from among the activated BWPs, and use the DC location corresponding to the two BWPs activated at the same time in message 3 as the DC location of the current communication. The activated BWP11, BWP21 and BWP31 are distributed in the frequency domain as shown in fig. 7. It can be seen that BWP11 is the BWP corresponding to the frequency position in the activated BWP and BWP31 is the BWP corresponding to the highest frequency position in the activated BWP. The network device may determine the corresponding DC location in message 3 as the DC location corresponding to the current intra band CA when BWP11 and BWP31 are activated simultaneously.

Based on this scheme, the terminal may send DC locations of corresponding communications to the network device for all possible simultaneously activated BWPs, pairwise, so that the network device may quickly determine the corresponding DC locations according to the activated BWPs in the current communication. And hence optimization of the communication. In addition, by this method, since a determination method of a DC position of a corresponding communication when a plurality of BWPs are activated is provided, accurate measurement of relevant RF performance in this scenario is facilitated.

It should be noted that, in the above description, it is described that the terminal determines a possible DC location according to pairwise combinations of BWPs that may be simultaneously activated in BWPs configured by the network device, and reports the DC location to the network device. It is understood that the network device may configure the BWP for the terminal by configuring multiple carrier (CC) for the terminal, where each CC includes multiple BWPs. In this example, the solution that the terminal determines that BWPs that are likely to be activated simultaneously are combined two by two may also be implemented by the following method:

taking a network device as a terminal, A1 CCs are configured, including a CC1 configured with B1 BWPs and a CC2 configured with B2 BWPs as an example. The terminal may select two CC from the A1 CCs to form a CC pair (CC pair), and report DC positions corresponding to pairwise combinations of all BWPs included in one CC pair in one report to the network device. For example, in the case where only 1 BWP can be activated in each CC at the same time, the CC pair consisting of CC1 and CC2 may include

Two-by-two combinations of BWPs are possible. Therefore, when reporting the DC position corresponding to the CC pair consisting of CC1 and CC2, the terminal may report to the network device

The possible BWPs combine the corresponding DC positions, respectively, two by two.

It is understood that, in the case that multiple BWPs can be activated simultaneously in each CC, the CC pair consisting of CC1 and CC2 may include

The possible BWPs combine the corresponding DC positions in pairs. The following takes as an example that 1 BWP can be activated simultaneously in each CC.

For other CC pairs, the terminal may also refer to the reporting mode of the information corresponding to CC1 and CC2, and report the DC position of the corresponding CC pair. For example, a network device is generally configured with A1 CCs (e.g., CC1, CC2, \8230; CCA 1) for a terminal, and one of the A1 CCsThe number of CC pair consisting of any 2 CCs is

K1 BWPs are arranged in CC1 of the kth CC pair, and k2 BWPs are arranged in CC2 of the kth CC pair. Wherein k is to

Are all positive integers, k1 and k2 are both positive integers, and any two numbers can be the same or different. Then, the terminal reports the total amount of the DC position to the network equipment as

When the maximum configurable BWP in each CC is considered to be 4, the total upper limit amount of the DC position reported by the terminal to the network equipment is

After the network device receives the information reported by the terminal, it may select a DC location corresponding to the corresponding BWP pairwise combination from possible pairwise combinations of BWPs in different CC pairs reported by the terminal according to the currently activated CC pair and the pairwise combination of activated BWPs in the activated CC pair, so as to obtain the DC location in the current communication process.

It should be understood that, in the current communication scheme, the terminal may send the DC location corresponding to the possible activated BWP to a currently camped cell (e.g., primary cell, PCell) for processing, and therefore, in other implementations of the present application, the terminal may further compress the data amount of the possible DC location sent to the network device with reference to the PCell. In the following description, a CC corresponding to Pcell may be referred to as a CCp.

In this example, the terminal may report the DC position corresponding to the possible pairwise combination of BWPs included in the CC pair consisting of CC1 and CC2 whose carrier frequency points satisfy the following conditions to the network device:

wherein the content of the first and second substances,

is the carrier frequency point of the CC1,

is the carrier frequency point of the CC2,

is the carrier frequency point of the CCP. CC1, CC2, and CCP are all included in a plurality of CCs configured for a terminal by a network device.

It can be understood that in a plurality of CCs configured by a network device for a terminal, there may be two cases in the location of the CCp according to the high and low orders of the carrier frequency point corresponding to each CC: in case 1, the carrier frequency point corresponding to the CCp is the highest or lowest carrier frequency point among the carrier frequency points of the plurality of CCs. In case 2, carrier frequency points greater than and less than the carrier frequency point corresponding to the CCp exist in the carrier frequency points of the multiple CCs. In this example, the two cases described above may be handled differently.

In case 1, the carrier frequency point corresponding to the CCp is the highest or lowest carrier frequency point among the carrier frequency points of the multiple CCs, that is, the carrier frequency point is

Or

That is to say, according to the method provided by the foregoing solution of the embodiment of the present application, when the BWP with the highest carrier frequency point and the BWP with the lowest carrier frequency point are selected from the BWPs in all activated CCs, one BWP (for example, the BWP with the highest carrier frequency point or the BWP with the lowest carrier frequency point) is the BWP in the CCp. Therefore, the terminal may fix one CC of the CC pair as the CCp when selecting the CC pair. For example, A1 CCs are configured by the network device as the terminal, and each CC includes A2 BWPs as an example. In this case 1, the terminal may determine CC pairs including ccps, including (A1-1) at most. Obviously, (A1-1)Is significantly less than

Therefore, the number of DC positions of CC reported by the terminal to the network device for the corresponding BWP combination is significantly reduced. Thereby, data communication pressure between the terminal and the network device can be reduced, while also enabling the network device to determine the current DC position therefrom more quickly.

In case 2, there are carrier frequency points greater than and less than the carrier frequency point corresponding to the CCp in the carrier frequency points of multiple CCs, that is

That is, in a plurality of CCs configured by the network device for the terminal, the carrier frequency point of the CCp is located at a middle position. It can be understood that in this case 2, the BWP corresponding to the CCp may not be the BWP with the highest carrier frequency point or the BWP with the lowest carrier frequency point in all the currently activated BWPs, and therefore, the DC position corresponding to the pairwise combination of more CC pairs corresponding to BWPs needs to be reported. In this example, the terminal device may use, as the CC pairs to be reported, all possible CC pairs, where a frequency range formed by the carrier frequency points of two CCs includes the carrier frequency point of the CCp. For example, a network device is configured with 4 CCs as a terminal, which are CC1, CC2, CC3, and CC4 respectively according to the frequency point of a carrier, and the CCp is CC 2. The terminal may form CC1 and CC2 into one CC pair, form CC1 and CC3 into one CC pair, and form CC1 and CC4 into one CC pair. The terminal may also form CC2 and CC3 into one CC pair, and form CC2 and CC4 into one CC pair. Because the range of the carrier frequency points corresponding to the CC pair consisting of the CC3 and the CC4 does not include the carrier frequency points corresponding to the CC2, the terminal does not need to report the DC position of every two combinations of BWPs corresponding to the CC pair consisting of the CC3 and the CC 4. It can be seen that, in this case 2, according to the above-described exemplary scheme, the DC positions of BWPs corresponding to CC pairs reported by the terminal are also compressed (for example, the possible DC positions corresponding to CC pairs consisting of CC3 and CC4 are not reported), so that the communication pressure between the terminal and the network device can be reduced, and the network device can find the DC positions corresponding to BWPs fasterThe purpose of the current DC position.

With reference to the foregoing description, an embodiment of the present application further provides a specific implementation example of a reporting mechanism in which a terminal is a network device and uses a CC as a unit.

In this example, the terminal may report a CC pair consisting of any 2 CCs in the N CCs configured for it by the network device. Such as can be identified as SEQUENCE (SIZE (1.. MaxNrofCellPairs)). That is, the terminal may report the cellids of the two CCs for each CCpair. In addition, the terminal may report all possibly simultaneously activated BWP pairs for each CC pair. Such as may be denoted as SEQUENCE (SIZE (1.. Maxnrofbwpspair)). In some implementations, in the information of the BWP pairs reported by the terminal, each BWP pair may contain two information elements: such as the DC location, identifies the location of the RE. This scheme can be implemented by the following identification: txDiretcurrentlocation-r 16 INTEREGER (0.. 3301). Wherein, the cell where the DC position is located is servCellIndex-r16servCellIndex.

The following gives specific protocol structures and corresponding described possible implementations corresponding to the above examples:

the uplink transmit direct current CA list element represents the transmit direct current DC location for each serving cell pair of the in-band uplink contiguous CA based on the BWP subcarrier spacing parameter (numerology) and associated carrier bandwidth.

The IE UplinkTxDirectCurrentListCA indicates the Tx Direct Current locations per serving cell pair for intra-band UL contiguous CA,based on the BWP numerology and the associated carrier bandwidth.

The structure may include a plurality of CC pair, that is, SEQUENCE (SIZE (1.. MaxNrofCellPairs)), and the reporting mode of each CC pair is to report the cellids of two CCs. For each CC pair, all BWP pairs that may be activated simultaneously, i.e. SEQUENCE (SIZE (1.. MaxNrofBWPsPairs), are reported, each BWP pair contains two information elements, DC position, cell where the position of RE and DC position are identified, an example of a structure is given below:

that is:

the uplink tx dc BWP pair field descriptions (uplinktxdiretcurrentbwppair field descriptions) corresponding to the above structure may include the following contents as shown in table 1:

TABLE 1

I.e. as shown in table 2:

TABLE 2

In this example, the uplink transmit dc cell pair field description (UplinkTxDirectCurrentCellPair field descriptions) may include the contents as shown in table 3:

TABLE 3

I.e. as shown in table 4:

TABLE 4

In some implementations, a definition of the number of maximum BWP pairs and/or the number of CC pairs that the system can accept may be included in the Multiplicity and type constraint definitions.

For example, the number of pairs of maximum BWPs may be defined as:

the maximum number of BWP pairs is integer = 16-the maximum number of BWP pairs per serving CC pair.

maxNrofBWPsPairs INTEGER::＝16 --Maximum number of BWPs pairs per serving cell pair

In this example, the maximum number of BWP pairs that can be included in each CC pair is 16. Of course, this is merely an example, and in other implementations, the maximum number may be other values. For example, when 5 BWPs are included in each CC, the maximum number may be 5 × 5= 25. As another example, when 8 BWPs are included in each CC, then the maximum number of BWP pairs may be 8 × 8= 64.

As another example, the definition of the maximum number of CC pairs may be:

maximum CC number integer = 256-maximum CC pair number in-band uplink CA.

maxNrofCellPairs INTEGER::＝256 --Maximum number cell pairs for intra-band UL CA

In this example, the maximum number of CC pairs that can be included in each CC pair is 256. Of course, this is merely an example, and in other implementations, the maximum number may be other values.
