[0061] It is worth noting that the technologies described in this application are not limited to Long Term Evolution (LTE) / LTE-Advanced (LTE-A) systems, but can also be used in other wireless communication systems, such as Code Division Multiple Access (CDMA), Time Division Multiple Access (TDMA), Frequency Division Multiple Access (FDMA), Orthogonal Frequency Division Multiple Access (OFDMA), Single-carrier Frequency-Division Multiple Access (SC-FDMA), and other systems. The terms "system" and "network device" in this application are often used interchangeably, and the described technologies can be used with the systems and radio technologies mentioned above, as well as with other systems and radio technologies. However, the following description describes New Radio (NR) systems for illustrative purposes, and the term NR is used in most of the following description, although these technologies can also be applied to applications other than NR systems, such as 6th Generation (6G) communication systems.

[0062] Figure 1This diagram illustrates a block diagram of a wireless communication system applicable to embodiments of this application. The wireless communication system includes a terminal 11 and a network device 12. The terminal 11 can also be referred to as a terminal device or user equipment (UE). The terminal 11 can be a mobile phone, tablet computer, laptop computer, personal digital assistant (PDA), handheld computer, netbook, ultra-mobile personal computer (UMPC), mobile internet device (MID), wearable device, vehicle-mounted device (VUE), pedestrian terminal (PUE), or other terminal-side devices.

The base station is not limited to specific technical terms. It should be noted that in this application embodiment, only the base station in the NR system is used as an example, but the specific type of base station is not limited.

[0063] For ease of understanding, the following describes some aspects of the embodiments of this application:

[0064] Terminals typically support one power amplifier (PA) or two PAs. A PA can cover one or more control squares (CCs), and a CC can cover multiple power pods (BWPs). A PA may have one DC position. For example, in frequency range (FR) band 1, a maximum of four BWPs can be configured on a single CC, one of which spans the entire CC. Figure 2As shown, carrier unit 1 is configured with bandwidth portion 11, bandwidth portion 12, bandwidth portion 13 and bandwidth portion 14, the bandwidth portion 14 spans carrier unit 1, and carrier unit 2 is configured with bandwidth portion 21, bandwidth portion 22, bandwidth portion 23 and bandwidth portion 24, the bandwidth portion 24 spans carrier unit 2.

[0065] Optionally, the DC location is generally the midpoint of the actually activated or configured BWP or CC. The DC location may vary depending on the actual frequency location activated by the terminal. The terminal can report the DC location information according to the cell and BWP, and report it via Radio Resource Control (RRC) messages.

[0066] The DC position processing method provided in this application will be described in detail below with reference to the accompanying drawings, through specific embodiments and application scenarios.

[0067] Please see Figure 3 , Figure 3 This is a flowchart of a DC position processing method provided in an embodiment of this application. The method is executed by a terminal, such as... Figure 3 As shown, it includes the following steps:

[0068] Step 301: The terminal determines the first information;

[0069] Step 302: The terminal sends the first information to the network device;

[0070] The first information is used to determine the DC location of at least one bandwidth portion BWP combination, and the first information includes at least one of the following:

[0071] First indication information, the first information being used to indicate the number of power amplifiers contained in the terminal, or to indicate whether the terminal contains at least two power amplifiers;

[0072] Number of DC position groups;

[0073] The second indication information is used to indicate whether the terminal supports the ability to adjust the DC position;

[0074] DC position algorithm information;

[0075] A preset list, which includes at least one set of target objects corresponding to the DC position group, wherein the target objects are carrier units (CC) or frequency bands (bands);

[0076] DC location information, which includes the index identifier of the BWP combination corresponding to the DC location.

[0077] In this embodiment, the first indication information, the number of DC position groups, and the second indication information can be understood as UE parameters used to assist the network device in determining the DC position. It should be understood that the network device can determine the current DC position of the terminal based on one or more of the UE parameters reported by the terminal, as well as other parameters (such as the algorithm for calculating the DC position). These parameters can be reported in advance by the terminal, agreed upon by the protocol, or carried in the first information. This allows the network device to determine the current DC position of the terminal based on the first information reported by the terminal.

[0078] The first indication information can directly indicate the number of PAs, or it can indicate whether the number of PAs is at least two power amplifiers. For example, when the first indication information indicates that the number of PAs is at least two PAs, the network device can default the number of PAs of the terminal to a fixed preset value, which is an integer greater than 1; when the first indication information indicates that the number of PAs is not at least two PAs, the network device can default the number of PAs of the terminal to one.

[0079] It should be understood that the aforementioned DC position group may include multiple possible DC position information, and each DC position group has only one active DC position at any given time. For example, when the terminal has multiple DC positions, these multiple DC positions correspond to different DC position groups. Optionally, in some embodiments, the DC position group may correspond to a PA (Power Aspect Ratio). For example, one DC position group corresponds to one PA, that is, the DC positions that a PA may appear in are divided into a DC position group. In the embodiments of this application, the DC position group includes one or more DC positions, and one DC position corresponds to a BWP (Browser Tool Potential) combination, indicating the DC position corresponding to the BWP combination.

[0080] Whether the aforementioned terminal supports the ability to adjust the DC position can be understood as whether the terminal has the ability to adjust the DC position in real time based on the activated BWP.

[0081] The terminal reporting the aforementioned DC position algorithm information can be understood as the terminal implicitly reporting its DC position. Network devices can determine the terminal's DC position based on the DC position algorithm information reported by the terminal.

[0082] The aforementioned preset list can be understood as a CC list or a frequency band list. The preset list may include at least one set of CCs or at least one set of frequency bands, where each set of CCs may correspond to one PA, and each set of frequency bands may correspond to one PA. This preset list can serve as auxiliary information to help network devices determine the DC location of terminals. In this embodiment, reporting the preset list can be understood as CC or frequency band grouping information.

[0083] Optionally, the terminal reporting DC location information can be understood as the terminal displaying and indicating DC location information. The network device can interpret the DC location information based on the UE parameters or CC and frequency band grouping information reported by the terminal in advance or in this report, thereby obtaining the DC location reported by the terminal.

[0084] In this embodiment, a terminal determines first information; the terminal sends the first information to a network device; wherein the first information is used to determine the DC position of at least one bandwidth portion (BWP) combination, and the first information includes at least one of the following: first indication information, which indicates the number of power amplifiers included in the terminal, or whether the terminal includes at least two power amplifiers; the number of DC position groups; second indication information, which indicates whether the terminal supports the ability to adjust the DC position; DC position algorithm information; a preset list, which includes at least one set of target objects corresponding to the DC position group, wherein the target objects are carrier units (CC) or frequency bands; and DC position information, which includes an index identifier of the BWP combination corresponding to the DC position. This eliminates the need for the terminal to report CC information, BWP information, and DC position for every possible DC position; instead, the network device determines the terminal's DC position based on the reported first information, thereby reducing the signaling overhead of DC position reporting.

[0085] Optionally, in some embodiments, the DC position algorithm information described above is used to indicate at least one of the following:

[0086] The DC position is determined based on a first CC, which includes the lowest frequency CC and the highest frequency CC among the configured CCs;

[0087] Determine the DC position based on the second CC;

[0088] The DC position is determined based on the first BWP, which includes the BWP in the second CC that is in the active state;

[0089] The DC position is determined based on the second BWP, which includes the BWP configured in the second CC;

[0090] The second CC includes the highest frequency CC and the lowest frequency CC among the activated CCs.

[0091] In this embodiment of the application, the network device can calculate the DC position of the terminal based on the DC position algorithm information reported by the terminal. The DC position may include one DC position or multiple DC positions, and no further limitation is made here.

[0092] Optionally, in some embodiments, the DC position information further includes at least one of the following:

[0093] BWP information indicating the DC location;

[0094] The third indication information is used to indicate the DC position in the BWP.

[0095] In this embodiment, the method for constructing the DC location information can be set according to actual needs. For example, in some embodiments, the DC location information satisfies any one of the following:

[0096] Determining the DC position based on the configuration or activation of the BWP;

[0097] Determined based on the DC position contained within the BWP range in the BWP combination.

[0098] Determining DC location information based on possible DC locations in a configured or activated BWP can be understood as follows: the terminal constructs DC location information according to PA or DC location group. The DC location information includes possible DC locations appearing in the configured or activated BWP, as well as the index identifier of the BWP combination corresponding to the DC location.

[0099] Optionally, when the UE reports DC locations in DC location groups, each DC location group corresponds to a CC list, including the BWP combinations within the corresponding CC. Each BWP combination contains two BWPs. The terminal indicates the DC location based on each BWP combination, and the DC location includes the following information: the BWP information where the DC location is located and the DC location within the BWP. The BWP information where the DC location is located is the BWP information within the BWP combination.

[0100] Determining DC location information based on DC locations within the BWP range of a BWP combination can be understood as: the terminal reporting based on the BWP combination. The DC location is indexed from the BWP combination, and the UE only reports the DC locations within the BWP range of the BWP combination. In this embodiment, when one DC location corresponds to multiple BWP combinations, only one DC location needs to be reported, along with the index identifier of the BWP combination associated with that DC location, thereby reducing the signaling overhead of DC location reporting.

[0101] It should be noted that the DC position can be indicated by the position indicator within the CC range, or by the position indicator in the maximum BWP, such as... Figure 2 As shown, the DC position of CC can be indicated based on the position in BWP14.

[0102] Optionally, in some embodiments, the BWP information of the DC position is indicated by a Boolean variable or a bitmap. For example, 2 bits of information can be used to identify which BWP in the BWP combination the DC position is on.

[0103] Optionally, in some embodiments, when the third indication information indicates that the target BWP includes at least two DC positions, the at least two DC positions satisfy:

[0104] The first DC position is indicated by an absolute position or by a first offset value, where the first offset value is the amount of offset of the first DC position relative to the starting point of the target BWP;

[0105] The second DC position is indicated by a second offset value, which is the offset value between the second DC position and the previous adjacent DC position;

[0106] Wherein, the first DC position is the DC position closest to the starting point of the target BWP among the at least two DC positions, and the second DC position is any DC position located after the first DC position.

[0107] It should be noted that in some embodiments, some DC positions can be implicitly indicated by the DC position algorithm information described above, while some DC positions can be indicated by display based on CC or BWP.

[0108] Optionally, in some embodiments, the index identifiers of the BWP combinations corresponding to the DC position are arranged in a preset combination order, which is agreed upon by the protocol or indicated by the network device.

[0109] For example, targeting Figure 2 Carrier unit 1, BWP11 and BWP12 are BWP combination 1, with a corresponding index identifier of 001; BWP11 and BWP13 are BWP combination 2, with a corresponding index identifier of 010; BWP11 and BWP14 are BWP combination 3, with a corresponding index identifier of 011; BWP12 and BWP13 are BWP combination 4, with a corresponding index identifier of 100; BWP12 and BWP14 are BWP combination 5, with a corresponding index identifier of 101; BWP13 and BWP14 are BWP combination 6, with a corresponding index identifier of 110.

[0110] It should be noted that the reporting of the aforementioned first information can be agreed upon by the protocol or requested by the network device. In other words, the step of the terminal sending the first information to the network device includes:

[0111] The terminal sends the first information to the network device based on the protocol agreement or the first reporting request sent by the network device.

[0112] In this embodiment of the application, the first reporting request is used to request the terminal to report at least one of the following:

[0113] First indication information, the first information being used to indicate the number of power amplifiers contained in the terminal, or to indicate whether the terminal contains at least two power amplifiers;

[0114] Number of DC position groups;

[0115] The second indication information is used to indicate whether the terminal supports the ability to adjust the DC position;

[0116] DC position algorithm information;

[0117] A preset list, the preset list including at least one set of target objects corresponding to the DC position group, the target objects being carrier units (CC) or frequency bands;

[0118] The frequency band range for DC location reporting.

[0119] It should be understood that, in the embodiments of this application, when the terminal reports first information based on the first reporting request, the reported first information can be determined based on the first reporting request. For example, when the first request is used to request the terminal to report first indication information, the aforementioned first information may include the first indication information. Of course, in other embodiments, in addition to including the first indication information, other content may also be reported, such as DC position algorithm information.

[0120] It should be noted that, in the embodiments of this application, the aforementioned first reporting request may include a Supplementary Uplink (SUL) reporting request.

[0121] Optionally, in some embodiments, before the terminal determines the first information, the method further includes:

[0122] The terminal sends second information to the network device based on the protocol agreement or the second reporting request sent by the network device;

[0123] The second piece of information mentioned above includes at least one of the following:

[0124] First indication information, the first information being used to indicate the number of power amplifiers contained in the terminal, or to indicate whether the terminal contains at least two power amplifiers;

[0125] Number of DC position groups;

[0126] The second indication information is used to indicate whether the terminal supports the ability to adjust the DC position;

[0127] DC position algorithm information;

[0128] A preset list, the preset list including at least one set of target objects corresponding to the DC position group, the target objects being carrier units (CC) or frequency bands;

[0129] BWP information indicating the DC location;

[0130] Third indication information, the third indication information being used for the DC position in the BWP;

[0131] The index identifier of the BWP combination corresponding to the DC position in the BWP.

[0132] Optionally, in some embodiments, the first information is used to add, modify, or delete content in the second information. For example, in some embodiments, the second information is UE parameters, i.e., the terminal first reports UE parameters or target object grouping information, and then reports CC or BWP information in the DC location information within the specific group. The CC or BWP information can be marked with a sequence number within the group. When the terminal subsequently reports the first information, the network device can interpret the first information based on the second information to determine the terminal's DC location. In this way, by reporting multiple times, the signaling overhead of a single report can be reduced.

[0133] To better understand this application, the implementation process of this application will be described in detail below through some embodiments.

[0134] Example 1: Reporting the mapping between PA and CC / band.

[0135] The terminal reports a message, which includes CC or Band packet information. Optionally, the report message can be sent via RRC signaling, such as RRC Setup Complete signaling, RRC Reconfiguration Complete signaling, UE Assistance Information, etc.

[0136] For example, an RRX signaling message is sent, which includes an uplink transmit DC CC group list (UplinkTxDirectCurrentListCCgroups), which contains multiple CC lists, each containing at least one CC group. Optionally, UplinkTxDirectCurrentListCCgroups can be replaced with an uplink transmit DC PA list, where one PA corresponds to one CC group.

[0137] Optionally, before reporting the message, the UE receives a request message 1 sent by the network device. The request message 1 requests the UE to report CC or Band packet information. Each CC or Band packet corresponds to a PA.

[0138] Further, the UE receives request message 2 sent by the network device. Request message 2 requests the UE to report DC location information. The UE reports DC location information. The DC location information includes at least one of the following:

[0139] BWP information where DC position is located

[0140] DC position in the BWP;

[0141] At least one BWP combination corresponding to the DC position.

[0142] Example 2: Compressed reporting of DC location information, using a method of indexing DC location to BWP combination.

[0143] 1. The UE receives a DC location reporting request sent by the network device.

[0144] 2. The UE reports DC location information.

[0145] The UE constructs DC location information. The UE first includes DC location information according to the PA or DC location group.

[0146] Each set of DC position information includes:

[0147] The BWP information it is located in, wherein the BWP is a BWP within the BWP range that may have a DC location in the configured or activated BWP;

[0148] DC position in BWP;

[0149] An index identifier for at least one BWP combination corresponding to a DC location. Optionally, the index identifier of the BWP combination includes the BWP combination ID with a default combination order. The default combination order of the BWP combinations is defined by the protocol.

[0150] For example, when DC position reporting is performed using the UplinkTxDirectCurrentListCCgroups mentioned above, the UplinkTxDirectCurrentListCCgroups contains multiple CClists. Each CClist contains at least one CC combination.

[0151] Each CC combination contains at least one txDirectCurrentLocationInfo (i.e., the DC location information).

[0152] Each txDirectCurrentLocationInfo contains:

[0153] DC position txDirectCurrentLocation;

[0154] Its location is in BWP (ServCellIndex);

[0155] And at least one BWP combination.

[0156] Optionally, the BWP combination can be an index identifier for the BWP combination, and the index identifiers of the BWP combination are arranged according to a default combination order. The default combination order of the BWP combinations can be agreed upon by protocol.

[0157] Optionally, when reporting multiple DC positions based on the same BWP, the DC positions are represented by absolute values ​​or offsets. When using offsets, the first position is an absolute position or an offset relative to the starting point of the BWP, and subsequent positions are offsets relative to the previous position.

[0158] Example 3: Only possible DC location information is reported according to the default BWP combined index.

[0159] 1. The UE receives a DC location reporting request sent by the network device.

[0160] 2. The UE reports DC location information.

[0161] Alternatively, one method for constructing DC location information is as follows: the UE first includes DC location information according to the PA or DC location group.

[0162] Each set of DC position information must include at least one of the following:

[0163] BWP combination information; the index identifier of the BWP combination is arranged according to the default combination order, wherein the default combination order of the BWP combinations can be agreed upon by protocol;

[0164] The BWP indicating the DC position; optionally, a Boolean variable (bool BWP) or a bitmap (such as 2-bit) can be used to indicate which BWP the DC position is on.

[0165] Optionally, bool BWP indicator = TRUE indicates that BWP is a combination of BWPs.<BWP1,BWP2> In BWP1; boolBWP indicator = FALSE, indicating that BWP is a combination of BWPs.<BWP1,BWP2> BWP2 in the middle.

[0166] Alternatively, a bitmap (e.g., 2-bit) can be used to indicate this. For example:
