The described technology may be used in the above-mentioned systems and radio technologies, as well as in other systems and radio technologies. However, in the following description, a New Radio (NR) system will be described for illustrative purposes, and NR terminology will be used in much of the following description, but these techniques may also be applied to systems other than NR systems, such as 6th generation (6G) systems. th It can also be applied to 6G (Generation, 6G) communication systems.

[0019] FIG. 1 shows a block diagram of a wireless communication system to which the embodiment of the present application can be applied. The wireless communication system includes a terminal 11 and a network device 12. The terminal 11 may be called a terminal device or a user terminal (User Equipment, UE), and the terminal 11 may be a terminal side device such as a mobile phone, a tablet personal computer, a laptop computer also called a notebook computer, a personal digital assistant (PDA), a palmtop computer, a netbook, an ultra-mobile personal computer (UMPC), a mobile Internet device (MID), a wearable device, a vehicle user equipment (VUE), a pedestrian user equipment (PUE), etc., and the wearable device includes a wristband, a headphone, a pair of glasses, etc. It should be noted that the specific type of the terminal 11 is not limited in the embodiment of the present application. The network device 12 may be a base station or a core network. Here, the base station may be referred to as a Node B, an evolved Node B, an access point, a base transceiver station (BTS), a radio base station, a radio transceiver, a basic service set (BSS), an extended service set (ESS), a B node, an evolved B node (eNB), a home B node, a home evolved B node, a wireless local area network (WLAN) access point, a wireless fidelity (WiFi) node, a transmitting receiving point (TRP), or any other suitable term in the art, and the base station is not limited to a specific technical term as long as a similar technical effect can be achieved.It should be noted that in the embodiments of the present application, a base station in an NR system is simply taken as an example, but the specific type of base station is not limited.

[0020] For ease of understanding, some contents related to the embodiments of the present application are described below.

[0021] A terminal can generally support one power amplifier (PA) or two PAs. One PA can cover one or multiple CCs, and one CC covers multiple BWPs. There can be one DC location on one PA. For example, in one frequency range (FR) band, up to four BWPs can be arranged on one CC, and one of them spans the entire CC. As shown in FIG. 2, a bandwidth portion 11, a bandwidth portion 12, a bandwidth portion 13, and a bandwidth portion 14 are arranged on a component carrier 1, and the bandwidth portion 14 spans the component carrier 1, and a bandwidth portion 21, a bandwidth portion 22, a bandwidth portion 23, and a bandwidth portion 24 are arranged on a component carrier 2, and the bandwidth portion 24 spans the component carrier 2.

[0022] Alternatively, the DC location is generally an intermediate location of the BWP or CC that is actually activated or placed. The DC location may vary according to the terminal's actually activated frequency location. The terminal reports DC location information according to the cell and BWP, and can report it via a Radio Resource Control (RRC) message.

[0023] Hereinafter, the DC location processing method provided in the embodiments of the present application will be described in detail in specific embodiments and its application scenarios with reference to the drawings.

[0024] Please refer to FIG. 3, which is a flow chart of a DC location processing method provided in an embodiment of the present application. The method is executed by a terminal, as shown in FIG. 3: A step 301 in which the terminal determines first information; Step 302, in which the terminal transmits the first information to a network device; wherein the first information is used to determine a DC location of at least one bandwidth portion BWP combination, the first information comprising: First indication information for indicating the number of power amplifiers included in the terminal or for indicating whether the terminal includes at least two power amplifiers; The number of DC location groups, Second indication information for indicating whether the terminal supports a capability of adjusting a DC location; DC location algorithm information; A preset list including at least one group of target objects corresponding to the DC location group, the target object being a component carrier CC or a band; and DC location information including an index identifier of a BWP combination corresponding to the DC location.

[0025] In the embodiment of the present application, the above first indication information, the number of DC location groups and the second indication information can be understood as UE parameters for assisting the network equipment in determining the DC location. It should be understood that the network equipment can be based on one or more of the UE parameters reported by the terminal and other parameters (e.g., algorithms for calculating DC location), and these parameters may be reported in advance by the terminal, may be promised by a protocol, or may be included in the above first information. Thus, the network equipment can determine the terminal's current DC location based on the first information reported by the terminal.

[0026] The first instruction information may directly indicate the number of PAs, or may indicate whether the number of PAs is at least two power amplifiers. For example, if the first instruction information indicates that the number of PAs is at least two PAs, the network device may default the number of PAs of the terminal to a fixed preset value which is an integer greater than 1; if the first instruction information indicates that the number of PAs is not at least two PAs, the network device may default the number of PAs of the terminal to one.

[0027] It should be understood that the DC location group may include multiple possible DC location information, and each DC location group has only one valid DC location at the same time, for example, when there are multiple DC locations in a terminal, the multiple DC locations correspond to different DC location groups. Optionally, in some embodiments, the DC location group may correspond to a PA, for example, one DC location group corresponds to one PA, that is, the possible DC locations in a PA are divided into one DC location group. In the embodiment of the present application, the DC location group includes one or more DC locations, one of which corresponds to one BWP combination and represents the DC location corresponding to the BWP combination.

[0028] Whether the above-mentioned terminal supports the ability to adjust the DC location can be understood as whether the terminal has the ability to adjust the DC location in real time based on the activated BWP.

[0029] When the terminal reports the DC location algorithm information, it can be understood that the terminal implicitly reports the DC location, and the network device can determine the DC location of the terminal based on the DC location algorithm information reported by the terminal.

[0030] The preset list can be understood as a CC list or a band list, and the preset list may include at least one group of CCs or at least one group of bands, and each group of CCs may correspond to one PA, and each group of bands may correspond to one PA. The preset list can be auxiliary information that assists the network device in determining the DC location of the terminal. In the embodiment of the present application, the report of the preset list can be understood as the report of CC or band grouping information.

[0031] Alternatively, the terminal reporting the DC location information can be understood as the terminal explicitly indicating the DC location information, and the network device can decode the DC location information based on the UE parameters or CC and band grouping information previously or currently reported by the terminal, and obtain the DC location reported by the terminal.

[0032] In an embodiment of the present application, first information is determined by a terminal, and the terminal transmits the first information to a network device, where the first information is used to determine a DC location of at least one bandwidth portion BWP combination, and the first information includes at least one of: first indication information for indicating the number of power amplifiers included in the terminal or indicating whether the terminal includes at least two power amplifiers; second indication information for indicating the number of DC location groups and whether the terminal supports the ability to adjust DC location; DC location algorithm information; a preset list including at least one group of target objects corresponding to the DC location group, the target object being a component carrier CC or a band; and DC location information including an index identifier of a BWP combination corresponding to a DC location. This eliminates the need to report CC information, BWP information, and DC location for each possible DC location from the terminal, and the network device determines the DC location of the terminal based on the reported first information, thereby reducing the signaling overhead of DC location reporting.

[0033] Optionally, in some embodiments, the DC location algorithm information is: determining a DC location based on a first CC including a CC having a lowest frequency and a CC having a highest frequency among the CCs placed; determining a DC location based on the second CC; determining a DC location based on the first BWP including an active BWP in the second CC; and determining a DC location based on a second BWP including a BWP located in a second CC; Here, the second CC includes the CC with the highest frequency and the CC with the lowest frequency among the activated CCs.

[0034] In an embodiment of the present application, the network device can calculate the DC location of the terminal based on the DC location algorithm information reported by the terminal, and the DC location may include one DC location or may include multiple DC locations, and is not further limited herein.

[0035] Optionally, in some embodiments, the DC location information is: BWP information with DC locations, and third indication information for indicating a DC location in the BWP.

[0036] In the embodiments of the present application, the construction method of the DC location information can be set according to actual needs. For example, in some embodiments, the DC location information is: determining based on possible DC locations in the deployed or activated BWP; and determining based on a DC location that is included in the BWP range in the BWP combination.

[0037] Determining DC location information based on possible DC locations in a deployed or activated BWP can be understood as the terminal constructing DC location information according to a PA or DC location group, and the DC location information includes possible DC locations in a deployed or activated BWP and index identifiers of BWP combinations corresponding to the DC locations.

[0038] Alternatively, when the UE reports the DC location according to the DC location grouping, each DC location group corresponds to a group of CC lists, and includes a BWP combination in the corresponding CC. Each BWP combination includes two BWPs. The UE indicates the DC location according to each BWP combination, and the DC location includes BWP information of the DC location and the DC location in the BWP. Wherein, the BWP information of the DC location is the BWP information in the BWP combination.

[0039] Determining DC location information based on the DC location included in the BWP range of the BWP combination means that the report based on the BWP combination of the terminal is indexed from the BWP combination to the DC location, and at this time, the terminal UE reports only the DC location included in the BWP range of the BWP combination. In this embodiment, when one DC location corresponds to multiple BWP combinations, only one DC location and the index identifier of the BWP combination related to the DC location need to be reported, thereby reducing the signaling overhead of the DC location report.

[0040] It should be noted that the DC location may be indicated by its position within the CC range or by its position in the maximum BWP, and as shown in FIG. 2, the DC location of the CC may be indicated based on its position in the BWP 14.

[0041] Optionally, in some embodiments, the BWP information of the DC location is indicated by a Boolean variable or a bitmap, for example, two bits of information can be used to identify which BWP of the BWP combination the DC location is in.

[0042] Optionally, in some embodiments, when the third indication information indicates that the target BWP includes at least two DC locations, the at least two DC locations include: a first DC location is indicated by an absolute position or by a first offset value that is an offset of the first DC location relative to a start point of the target BWP; the second DC location being indicated by a second offset value that is an offset value of the second DC location relative to a previous adjacent DC location; Here, the first DC location is the DC location closest to the start point of the target BWP among the at least two DC locations, and the second DC location is any DC location located after the first DC location.

[0043] It should be noted that in some embodiments, some DC locations may be implicitly indicated by the above DC location algorithm information, and some DC locations may be explicitly indicated based on the CC or BWP.

[0044] Optionally, in some embodiments, the index identifiers of the BWP combinations corresponding to the DC locations are arranged according to a predetermined combination order, the predetermined combination order being promised by a protocol or instructed by the network device.

[0045] For example, for component carrier 1 in FIG. 2, BWP11 and BWP12 are BWP combination 1 and the corresponding index identifier is 001. BWP11 and BWP13 are BWP combination 2 and the corresponding index identifier is 010. BWP11 and BWP14 are BWP combination 3 and the corresponding index identifier is 011. BWP12 and BWP13 are BWP combination 4 and the corresponding index identifier is 100. BWP12 and BWP14 are BWP combination 5 and the corresponding index identifier is 101. BWP13 and BWP14 are BWP combination 6 and the corresponding index identifier is 110.

[0046] It should be noted that the reporting of the first information may be promised by a protocol or requested by a network device. In other words, the step of the terminal transmitting the first information to the network device includes: The method includes a step of the terminal transmitting the first information to the network device based on a first report request promised by a protocol or transmitted from the network device.

[0047] In an embodiment of the present application, the first reporting request comprises: First indication information for indicating the number of power amplifiers included in the terminal or for indicating whether the terminal includes at least two power amplifiers; The number of DC location groups, Second indication information for indicating whether the terminal supports a capability of adjusting a DC location; DC location algorithm information; A preset list including at least one group of target objects corresponding to the DC location group, the target object being a component carrier CC or a band; and a band range of a DC location report from the terminal.

[0048] It should be understood that in the embodiment of the present application, when the terminal reports the first information based on the first report request, the first information to be reported can be determined based on the first report request. For example, when the first request is used to request the terminal to report the first indication information, the first information may include the first indication information, and of course, in other embodiments, in addition to including the first indication information, other contents such as DC location algorithm information may be reported.

[0049] It should be noted that in the embodiment of the present application, the first report request may include a Supplementary Uplink (SUL) report request.

[0050] Optionally, in some embodiments, before the step of the terminal determining the first information, the method further comprises: The terminal further includes transmitting second information to the network device based on a second report request promised by a protocol or transmitted from the network device; Here, the second information is First indication information for indicating the number of power amplifiers included in the terminal or for indicating whether the terminal includes at least two power amplifiers; The number of DC location groups, Second indication information for indicating whether the terminal supports a capability of adjusting a DC location; DC location algorithm information; A preset list including at least one group of target objects corresponding to the DC location group, the target object being a component carrier CC or a band; BWP information with DC locations, a third indication for indicating a DC location in the BWP; and and an index identifier of a BWP combination corresponding to a DC location in the BWP.

[0051] Optionally, in some embodiments, the first information is used to add, modify or delete the content of the second information. For example, in some embodiments, the second information is a UE parameter, that is, the terminal first reports the UE parameter or the grouping information of the target object, and then reports the CC or BWP information of the DC location information of the specific grouping, and the CC or BWP information can be marked with a serial number in the group. When the terminal subsequently reports the first information, the network device can decode the first information based on the second information and determine the DC location of the terminal. This can reduce the signaling overhead of one report by multiple reports.

[0052] In order to make the present application better understood, the following describes in detail the process of implementing the present application through several examples.

[0053] In Example 1, the mapping of PA and CC / band is reported.

[0054] The terminal reports a message, and the report message includes CC or Band grouping information. Optionally, the report message can be sent via RRC signaling, such as RRC Setup Complete signaling, RRC Reconfiguration Complete signaling, and UE Assistance Information.

[0055] For example, send an RRX signaling, the RRX signaling includes an uplink transmit direct current CC group list (UplinkTxDirectCurrentListCCgroups), the UplinkTxDirectCurrentListCCgroups includes a plurality of CC lists, each CC list includes at least one CC combination. Optionally, the UplinkTxDirectCurrentListCCgroups can be replaced with an uplink transmit direct current PA list, where one PA corresponds to one CC group.

[0056] Optionally, before reporting the message, the UE receives a request message 1 sent from a network device, the request message 1 requests the UE to report CC or Band grouping information, each of the CC or Band grouping corresponding to one PA.

[0057] Furthermore, the UE receives a request message 2 sent from the network device. The request message 2 requests the UE to report DC location information, and the UE reports the DC location information. The DC location information includes: BWP information with DC locations, DC location in the BWP; and at least one BWP combination corresponding to a DC location.

[0058] In the second embodiment, the DC location information is compressed and reported according to the method of indexing from the DC location to the BWP combination.

[0059] 1. The UE receives a DC location report request sent from a network device.

[0060] 2. The UE reports DC location information.

[0061] Here, the UE constructs DC location information. The UE first includes the DC location information in the PA or DC location group.

[0062] The DC location information for each set is BWP information with DC locations, DC location in BWP and and an index identifier of at least one BWP combination corresponding to a DC location; Here, for BWP information with a DC location, the BWP is a BWP that may have a DC location within the BWP range of the deployed or activated BWP. For at least one BWP combination index identifier corresponding to a DC location, optionally, the BWP combination index identifier includes a BWP combination ID of a default combination order, where the default combination order of the BWP combination is promised by the protocol.

[0063] For example, the DC location is reported through the UplinkTxDirectCurrentListCCgroups, where the UplinkTxDirectCurrentListCCgroups includes a number of CClists, each of which includes at least one CC combination.

[0064] Each CC combination includes at least one txDirectCurrentLocationInfo (ie, the DC location information).

[0065] Each txDirectCurrentLocationInfo is DC location txDirectCurrentLocation, BWP (ServCellIndex) with DC location, and at least one BWP combination.

[0066] Alternatively, the BWP combination may be an index identifier of the BWP combination, and the index identifier of the BWP combination may be arranged in a default combination order, where the default combination order of the BWP combination may be promised by the protocol.

[0067] Optionally, when multiple DC locations are reported based on the same BWP, the DC locations are expressed as absolute values ​​or as offsets, where the first location is an offset relative to the absolute location or BWP start point, and all subsequent locations are offsets relative to the previous location.

[0068] In the third embodiment, only possible DC location information according to the default BWP combination index is reported.

[0069] 1. The UE receives a DC location report request sent from a network device.

[0070] 2. The UE reports DC location information.

[0071] Alternatively, in one DC location information construction method, the UE first includes the DC location information in the PA or DC location group.

[0072] Each set of DC location information includes at least one of BWP combination information and a BWP indication of the DC location. Here, the BWP combination information may be an index identifier of the BWP combination, and the index identifier of the BWP combination may be arranged in a default combination order, where the default combination order of the BWP combination may be promised by a protocol. For BWP indications with DC locations, optionally use a Boolean variable (bool BWP) or a bitmap (eg 2 bits) to indicate which BWP the DC location is in.

[0073] Optionally, if bool BWP_indicator = TRUE, the BWP is a BWP combination.<BWP1,BWP2> If bool BWP indication = FALSE, the BWP is a BWP combination.<BWP1,BWP2> Indicates that this is BWP2.

[0074] Alternatively, it can be specified using a bitmap (e.g. 2bit). For example, 01 BWP is BWP combination<BWP1,BWP2> Indicates that this is BWP1 in the 10 BWP is BWP combination<BWP1,BWP2> Indicates that this is BWP2.

[0075] In the fourth embodiment, the reporting is implicit based on UE parameters and algorithm information.

[0076] 1. UE receives a DC location report request sent from a network device, The DC location report request includes at least one of a report of the number of PAs or a report of whether to use multiple PAs, a report of whether to support Tuning capability, and DC location algorithm information. The Tuning capability refers to the capability of the UE to adjust the DC location in real time based on the activated BWP.

[0077] 2. The UE sends a message to report DC location information. The DC location information is: UE parameters reported by the UE, including the number of PAs, the number of DC location groups, Tuning capabilities, etc.; Two or more CC or band grouping information, each of which corresponds to one PA, reported by the UE; and and DC location algorithm information. The DC location algorithm information may be agreed upon by a protocol. The DC location algorithm information indicates a method or factor of DC location calculation by the UE; determining a DC location based on a first CC including a CC having a lowest frequency and a CC having a highest frequency among the CCs placed; determining a DC location based on the second CC; determining a DC location based on the first BWP including an active BWP in the second CC; determining a DC location based on a second BWP that includes a BWP located on a second CC; Here, the second CC includes the CC with the highest frequency and the CC with the lowest frequency among the activated CCs.

[0078] 3. The network equipment receives the DC location report of the UE.

[0079] The network device calculates the DC location of the UE based on the DC location algorithm information and uplink Carrier Aggregation (CA) configuration information reported by the UE.
