Description

Technical Field

[0001] This invention relates to the field of communications, and more particularly to an information reporting method and a communication device. Background Technology

[0002] Current wireless communication systems, such as WiFi and Long Term Evolution (LTE), are based on half-duplex transmission, meaning that the same device is not allowed to transmit and receive simultaneously on the same carrier or the same time-frequency resources. Recently, the 3rd Generation Partnership Project (3GPP) plenary meeting proposed subband full duplex (SBFD), which jointly schedules terminal devices operating in half-duplex mode, enabling access network equipment (such as base stations) to transmit and receive simultaneously, achieving full-duplex on the access network equipment side. Full-duplex operation on the access network equipment side is subband full duplex, meaning simultaneous transmission and reception on different subbands of the same carrier. Subband full duplex can also be called X-division duplex (XDD), or full duplex, etc. For example, as... Figure 1 As shown, for a certain time division duplex downlink (TDD DL) slot, a portion of the subband in that slot can be selected for uplink (UL) transmission.

[0003] Typically, the direct current (DC) component of the active bandwidth part (BWP) of a terminal device in the serving cell can affect the transmission between the terminal device and the access network equipment. After the introduction of SBFD, reducing the impact of DC in the SBFD time slots on the transmission between the terminal device and the access network equipment is a pressing technical problem that needs to be solved. Summary of the Invention

[0004] This application provides an information reporting method and communication device, which helps to reduce the adverse effects of DC in the SBFD time slot on the transmission between terminal equipment and access network equipment.

[0006] Receive a first signaling message, which carries first indication information and configuration information of a sub-band full-duplex SBFD. The configuration information is used to configure a first portion bandwidth (BWP) associated with the uplink transmission sub-band of the SBFD. The first indication information indicates the frequency domain location information of the reported DC component. Send a second indication information, which indicates the frequency domain location information of the DC component of the first BWP, wherein the frequency domain location information of the DC component of the first BWP is the same as the frequency domain location information of the DC component of the uplink transmission sub-band of the SBFD; or, the second indication information indicates the frequency domain location information of the DC component of the uplink transmission sub-band of the SBFD.

[0007] Based on the method described in the first aspect, access network equipment can accurately determine the frequency domain location information of the DC component of the uplink transmission subband of SBFD, thereby enabling resource scheduling and other operations to reduce the adverse effects of the DC component in the SBFD time slot on the transmission between the terminal equipment and the access network equipment.

[0060] In some possible implementations, the terminal device can be deployed on land, including indoors or outdoors, handheld, wearable, or vehicle-mounted; it can be deployed on water (such as ships); or it can be deployed in the air (such as airplanes, balloons, and satellites).

[0061] In some possible implementations, the terminal device may include means for wireless communication functionality, such as a chip system, a chip, or a chip module. For example, the chip system may include a chip, and may also include other discrete devices.

[0062] In some possible implementations, the terminal device described in the embodiments of this application may be a chip, chip module, device, unit, etc., and there are no specific limitations on it.

[0063] II. Access Network Equipment

[0064] Access network equipment can be a device with transceiver capabilities, which can be used to communicate with terminal devices.

[0065] In some possible implementations, access network devices can be responsible for radio resource management (RRM), quality of service (QoS) management, data compression and encryption, and data transmission and reception on the air interface side.

[0066] In some possible implementations, access network equipment may include base stations (BS) in a communication system or equipment deployed in a radio access network (RAN) to provide wireless communication functions; that is, access network equipment may include equipment in the RAN.

[0067] For example, devices in the RAN may include evolved node B (eNB or eNodeB) in the LTE communication system, next generation evolved node B (ng-eNB) in the NR communication system, next generation node B (gNB) in the NR communication system, master node (MN) in the dual connectivity architecture, and secondary node (SN) in the dual connectivity architecture, etc., without specific restrictions.

[0068] In some possible implementations, access network devices may include devices in the core network (CN).

[0069] For example, devices in a CN may include access and mobility management function (AMF), user plane function (UPF), session management function (SMF), etc.

[0070] In some possible implementations, access network devices can also be access points (APs) in WLANs, relay stations, communication devices in future PLMN networks, communication devices in NTN networks, etc.

[0071] In some possible implementations, the access network device may include means for providing wireless communication capabilities to terminal devices, such as a chip system, a chip, or a chip module. For example, the chip system may include a chip, or it may include other discrete devices.

[0072] In some possible implementations, access network devices can communicate with Internet Protocol (IP) networks, such as the Internet, private IP networks, or other data networks.

[0073] In some possible implementations, the access network device may include a single independent node to implement the functions of the aforementioned base station, or it may include two or more independent nodes to implement the functions of the aforementioned base station. For example, the access network device includes a centralized unit (CU) and a distributed unit (DU), such as gNB-CU and gNB-DU. Furthermore, in some other embodiments of this application, the access network device may also include an active antenna unit (AAU). The CU implements some of the functions of the access network device, and the DU implements other functions. For example, the CU is responsible for handling non-real-time protocols and services, implementing the functions of the radio resource control (RRC) layer, service data adaptation protocol (SDAP) layer, and packet data convergence protocol (PDCP) layer. The DU is responsible for handling physical layer protocols and real-time services, implementing the functions of the radio link control (RLC) layer, medium access control (MAC) layer, and physical (PHY) layer. In addition, the AAU can implement some physical layer processing functions, radio frequency processing, and related functions of the active antenna. Since RRC layer information ultimately becomes PHY layer information, or is derived from PHY layer information, in this network deployment, higher-layer signaling (such as RRC signaling) can be considered to be generated by the CU and sent by the DU, or jointly sent by the DU and AAU. It is understood that access network equipment can include at least one of CU, DU, and AAU. Furthermore, the CU can be classified as RAN equipment, or it can be classified as core network equipment; there are no specific limitations on this.

[0074] In some possible implementations, the access network device can be any site in a multi-site coherent joint transmission (CJT) with the terminal device, or another site outside of that multi-site group, or other access network devices communicating with the terminal device via the network; no specific limitations are imposed. Multi-site coherent joint transmission can be joint coherent transmission by multiple sites, or different data belonging to the same physical downlink shared channel (PDSCH) being sent from different sites to the terminal device, or multiple sites being virtually merged into one site for transmission. Names with the same meaning as those specified in other standards also apply to this application; that is, this application does not limit the names of these parameters. The sites in multi-site coherent joint transmission can be remote radio heads (RRHs), transmission and reception points (TRPs), access network devices, etc., without specific limitations.

[0075] In some possible implementations, the access network device can be any one of the multiple sites performing noncoherent cooperative transmission with the terminal device, or other sites outside of the multiple sites, or other access network devices communicating with the terminal device. No specific limitations are imposed on this. The multi-site noncoherent cooperative transmission can be a joint noncoherent transmission by multiple sites, or different data belonging to the same PDSCH being sent to the terminal device from different sites, or different data belonging to the same PDSCH being sent to the terminal device from different sites. Names with the same meaning as those specified in other standards also apply to this application; that is, this application does not limit the names of these parameters. The sites in the multi-site noncoherent cooperative transmission can be RRH, TRP, access network devices, etc., without specific limitations.

[0076] In some possible implementations, the access network equipment can have mobility characteristics; for example, the access network equipment can be a mobile device.

For example, the satellite can be a low-earth orbit (LEO) satellite, a medium-earth orbit (MEO) satellite, a geostationary earth orbit (GEO) satellite, a high-elliptical orbit (HEO) satellite, etc. Optionally, the access network equipment can also be a base station located on land, water, or other similar locations.

[0077] In some possible implementations, access network equipment can provide services to a cell, and terminal equipment within that cell can communicate with the access network equipment via transmission resources (such as spectrum resources). This cell can be a macro cell, small cell, metro cell, micro cell, pico cell, or femto cell, etc.

[0078] In some possible implementations, the access network device described in the embodiments of this application may be a chip, chip module, device, unit, etc., and there are no specific limitations on it.

[0079] To facilitate understanding of the embodiments of this application, the relevant names or terms involved in this application will be described below.

[0080] I. BWP

[0081] A Block-Based Resource (BWP) is defined as a combination of multiple contiguous resource blocks (RBs) within a single carrier. The concept of BWP was introduced primarily to allow terminals to better utilize large carrier bandwidths. For a large carrier bandwidth, such as 100MHz, the bandwidth required by a terminal is often limited. If the terminal were to perform real-time full-bandwidth detection and maintenance, energy consumption would pose a significant challenge. The introduction of the BWP concept allocates a portion of the bandwidth within the entire large carrier for terminal access and data transmission. The terminal only needs to perform corresponding operations within the bandwidth configured by the system.

[0082] II. Sub-band

[0083] Carrier bandwidth can be considered as a type of broadband, comprising at least one carrier wave plate (BWP). Each BWP comprises at least one contiguous sub-band. Each sub-band comprises at least one contiguous physical resource block (PRB). Alternatively, carrier bandwidth comprises at least one PRB. One or more contiguous PRBs in the frequency domain can constitute a sub-band. In the frequency domain, each PRB comprises 12 contiguous subcarriers.

[0084] III. Direct Current (DC) Component

[0085] The DC (orthogonal frequency division multiplexing) channel is the center of the downlink carrier in Long Term Evolution (LTE) and is an unused subcarrier located at the center of the downlink carrier. It is set up to avoid high interference caused by potential leakage from the local crystal oscillator and is generally not used for data transmission. In the uplink, the transmitted signal of the terminal device is also affected by the DC. NR (Normally Redirecting) uses OFDM technology and is also affected by the DC; the terminal device needs to report its DC frequency domain position in the uplink BWP (Bandwidth Positioner).

[0086] To reduce the adverse effects of DC in the SBFD time slot on the transmission between terminal equipment and access network equipment, embodiments of this application provide an information reporting method and a communication device. The information reporting method and communication device provided in this application embodiment are further described below:

[0087] Please see Figure 3 , Figure 3 This is a flowchart illustrating an information reporting method provided in an embodiment of this application. The information reporting method includes steps 301 to 302. Figure 3 The method shown can be executed by a terminal device and an access network device, or by a chip in the terminal device and a chip in the access network device. Figure 3 The method shown can also be implemented by other types of products, and those skilled in the art can make further extensions based on the content disclosed in the specification. Figure 3 The method shown takes terminal devices and access network devices as examples of the entities that perform the execution. Among them:

[0088] 301. The access network device sends a first signaling message to the terminal device. The first signaling message carries first indication information and SBFD configuration information. The configuration information is used to configure the first BWP associated with the uplink transmission subband of the SBFD. The first indication information indicates the frequency domain location information of the reported DC component. Accordingly, the terminal device can receive the first signaling message.

[0089] In this embodiment, the communication system in which the access network device and the terminal device reside can be a time-division duplex (TDD) system. The access network device can be the access network device of the primary serving cell. The access network device can send SBFD configuration information to the terminal device to configure SBFD for the terminal device, so that the terminal device can perform uplink transmission in the original downlink time slot in a timely manner, such as performing uplink hybrid automatic repeat request (HARQ) feedback.

[0090] In this embodiment of the application, the configuration information of SBFD is used to configure the first BWP associated with the uplink transmission subband of SBFD. This can be understood as follows: the configuration information of SBFD is used to configure the uplink transmission subband of SBFD on the first BWP, that is, the first BWP only includes the uplink transmission subband of SBFD, or the uplink transmission subband of SBFD is a part of the first BWP.

[0091] For example, if the first BWP only includes the uplink transmission subband of SBFD, the first BWP can be an uplink transmission subband specifically configured for SBFD by the access network equipment. The first BWP is not used for transmission by the terminal equipment in time slots outside of the SBFD time slots. SBFD time slots refer to the time slots in which the terminal equipment can only use the SBFD uplink transmission subband for uplink transmission; in other time slots, the terminal equipment cannot use the SBFD uplink transmission subband for uplink transmission. In some time slots, uplink transmission can be performed only for a portion of the duration, such as within 7 OFDM symbol lengths, using the SBFD uplink transmission subband.

[0092] For example, when the uplink transmission subband of SBFD is part of the first BWP, the first BWP can be used not only for uplink transmission within the SBFD time slot but also for transmission by the terminal device in time slots outside the SBFD time slot. For instance, before configuring SBFD, the access network device may have already configured the terminal device to transmit via the first BWP, such as downlink transmission via the downlink of the first BWP and uplink transmission via the uplink of the first BWP. The first BWP can be further divided into a first uplink BWP and a first downlink BWP, in which case the identifiers of these two BWPs are the same. Alternatively, when configuring SBFD for the terminal device, the access network device may simultaneously configure the first BWP for uplink transmission within the SBFD time slot and for transmission in time slots outside the SBFD time slot.

[0093] Optionally, if the uplink transmission subband of the SBFD is part of the first BWP, the configuration information of the SBFD can also configure the uplink transmission subband of the SBFD. For example, the configuration information of the SBFD can also configure the starting position of the uplink transmission subband of the SBFD on the first BWP and / or the bandwidth of the uplink transmission subband, and can also configure the subcarrier spacing used by the uplink transmission subband of the SBFD.

[0094] Optionally, the SBFD configuration information can also configure the SBFD time slots, i.e., the time slots in which SBFD is applied.

[0095] In this embodiment, the first indication information indicates the frequency domain location information of the reported DC component. Since the first indication information is sent together with the configuration information of the SBFD, even if the first indication information only indicates the frequency domain location information of the reported DC component, the terminal device can understand that the access network device wants the terminal device to report the frequency domain location information of the DC component of the uplink transmission subband of the SBFD. The terminal device can send information to the access network device based on the first indication information to determine the frequency domain location information of the DC component of the uplink transmission subband of the SBFD.

[0096] In one possible embodiment, the first indication information indicating the frequency domain location information of the reported DC component may be implemented as follows: the first indication information indicates the frequency domain location information of the DC component of the uplink transmission subband of the SBFD. Based on this possible embodiment, the frequency domain location information of the DC component of the uplink transmission subband of the SBFD can be more clearly indicated to the terminal device, thereby avoiding errors in reporting by the terminal device.

[0097] In one possible embodiment, the first indication information and the configuration information of SBFD can be located in two separate RRC signaling messages. For example, the access network device first configures the relevant parameters of SBFD through RRC reconfiguration signaling, and then notifies the terminal device to report the frequency domain location information of the DC component by carrying the first indication information through another RRC reconfiguration signaling message.

[0098] 302. The terminal device sends second indication information to the access network device. The second indication information indicates the frequency domain location information of the DC component of the first BWP, wherein the frequency domain location information of the DC component of the first BWP is the same as the frequency domain location information of the DC component of the uplink transmission subband of the SBFD; or, the second indication information indicates the frequency domain location information of the DC component of the uplink transmission subband of the SBFD. Accordingly, the access network device may receive the second indication information.

[0099] In this embodiment, the second indication information has two indication methods. One method is to indicate the frequency domain position information of the DC component of the first BWP. In this case, the frequency domain position information of the DC component of the first BWP is the same as the frequency domain position information of the DC component of the uplink transmission subband of the SBFD. Therefore, even if the second indication information indicates the frequency domain position information of the DC component of the first BWP, the access network device can determine the frequency domain position information of the DC component of the uplink transmission subband of the SBFD based on the second indication information. The other indication method is to directly indicate the frequency domain position information of the DC component of the uplink transmission subband of the SBFD. In this way, the access network device can also determine the frequency domain position information of the DC component of the uplink transmission subband of the SBFD based on the second indication information.

[0100] In one possible embodiment, the first signaling is a radio resource control (RRC) reconfiguration signaling, and the second indication information is carried in the RRC reconfiguration completion signaling.

[0101] In another possible embodiment, the first signaling is RRC recovery signaling, and the second indication information is carried in the RRC recovery completion signaling.

[0102] The following describes several possible implementations of the frequency domain position information of the DC component of the second indication information, which indicates whether the first BWP or SBFD is used:

[0103] (1) The first BWP contains only the uplink transmission subband of the SBFD, and the second indication information indicates the frequency domain position information of the DC component of the first BWP.

[0104] Since the first BWP only contains the uplink transmission subband of the SBFD, i.e., it uses an independent BWP to configure the uplink transmission subband of the SBFD, the frequency domain location information of the DC component of the first BWP is the same as the frequency domain location information of the DC component of the uplink transmission subband of the SBFD. Therefore, the terminal device can notify the access network device of the frequency domain location information of the DC component of the uplink transmission subband of the SBFD by indicating the frequency domain location information of the DC component of the first BWP. For example, the second indication information can use an existing cell structure dedicated to BWPs to indicate the frequency domain location information of the DC component of the first BWP. By using the second indication information to indicate the frequency domain location information of the DC component of the first BWP to notify the access network device of the frequency domain location information of the DC component of the uplink transmission subband of the SBFD, the existing cell structure dedicated to BWPs can be reused to indicate the frequency domain location information of the DC component of the first BWP, which helps to reduce implementation complexity.

[0105] For example, after a terminal device connects to the access network device of a TDD system, it establishes an RRC connection with the access network device, then establishes a Data Radio Bearer (DRB), and begins data transmission with the access network device. The access network device configures two Baseband Window (BWP) for the terminal device: an initial BWP and BWP1. The access network device instructs the terminal device via RRC reconfiguration signaling to report the frequency domain location information of the DC component. In the RRC reconfiguration completion signaling, the terminal device reports the frequency domain location information of the DC component corresponding to the initial BWP and the frequency domain location information of the DC component corresponding to BWP1.

[0106] After a period of time, the access network device wants to configure SBFD for the terminal device so that the terminal device can perform uplink transmission in the original downlink time slot, such as performing uplink HARQ feedback. The access network device sends SBFD configuration information to the terminal device. This configuration information is used to configure the uplink transmission subband of SBFD as BWP2. BWP2 is specifically configured for SBFD by the access network device, and BWP2 only includes the uplink transmission subband of SBFD.

[0107] The access network device sends the SBFD configuration information to the terminal device through RRC reconfiguration signaling, and at the same time carries the first indication information in the RRC reconfiguration signaling, which indicates that the frequency domain location information of the DC component needs to be reported.

[0108] After receiving the RRC reconfiguration signaling, the terminal device obtains the configuration information of the SBFD and, based on the first indication information, learns the frequency domain location information of the DC component of the uplink transmission subband of the SBFD that needs to be reported. The terminal device can send an RRC reconfiguration completion signaling to the access network device. The RRC reconfiguration completion signaling carries second indication information, which indicates the frequency domain location information of the DC component of BWP2. Since BWP2 only includes the uplink transmission subband of the SBFD, the frequency domain location information of the DC component of BWP2 is the same as that of the DC component of the uplink transmission subband of the SBFD. Therefore, the access network device can determine the frequency domain location information of the DC component of the uplink transmission subband of the SBFD based on the frequency domain location information of the DC component of BWP2.

[0109] In one possible embodiment, the second indication information can indicate the frequency domain location information of the DC component of the first BWP using existing cells dedicated to the BWP. For example, the second indication information can be an UplinkTxDirectCurrentBWP, and the cell structure can be as follows:

[0110]

[0111]

[0112] Here, bwp-Id is the identifier of the first BWP. shift7dot5kHz indicates whether the terminal device should offset by 7.5kHz when performing uplink transmission in the SBFD time slot. txDirectCurrentLocation indicates the frequency domain location information of the DC component of the first BWP.

[0113] In another possible embodiment, where the first BWP only contains the uplink transmission subband of the SBFD, the second indication information can also directly indicate the frequency domain location information of the DC component of the uplink transmission subband of the SBFD. For example, the frequency domain location information of the DC component of the uplink transmission subband of the SBFD can be indicated by a cell dedicated to the SBFD.

[0114] For example, the second indication information could be SBFDUplinkTxDirectCurrentBWP, and the cell structure could be as follows:

[0115]

[0116] Here, bwp-Id is the identifier of the first BWP. shift7dot5kHz indicates whether the terminal device should offset by 7.5kHz when performing uplink transmission in the SBFD time slot. txDirectCurrentLocation indicates the frequency domain location information of the DC component of the uplink transmission subband of the SBFD. The second indication information can also be a cell name other than SBFDUplinkTxDirectCurrentBWP, or SBFDUplinkTxDirectCurrentBWP may not include bwp-Id, or may include other content.

[0117] (2) The uplink transmission subband of the SBFD is a part of the first BWP; the second indication information indicates the frequency domain position information of the DC component of the uplink transmission subband of the SBFD.

[0118] For example, after a terminal device connects to the access network device of a TDD system, it establishes an RRC connection with the access network device, then establishes a Data Radio Bearer (DRB), and begins data transmission with the access network device. The access network device configures two Baseband Window (BWP) for the terminal device: an initial BWP and BWP1. The access network device instructs the terminal device via RRC reconfiguration signaling to report the frequency domain location information of the DC component. In the RRC reconfiguration completion signaling, the terminal device reports the frequency domain location information of the DC component corresponding to the initial BWP and the frequency domain location information of the DC component corresponding to BWP1.

[0119] After a period of time, the access network device wants to configure SBFD for the terminal device so that the terminal device can perform uplink transmission in the original downlink time slot, such as performing uplink HARQ feedback. The access network device sends SBFD configuration information to the terminal device. This configuration information is used to configure the uplink transmission subband of SBFD as a part of BWP1, and to configure the starting position and bandwidth of the uplink transmission subband of SBFD on BWP1. That is to say, BWP1 is not only used for uplink transmission in the SBFD time slot, but can also be used for the terminal device to transmit in time slots outside the SBFD time slot.

[0120] The access network device sends the SBFD configuration information to the terminal device through RRC reconfiguration signaling, and at the same time carries the first indication information in the RRC reconfiguration signaling, which indicates that the frequency domain location information of the DC component needs to be reported.

[0121] After receiving the RRC reconfiguration signaling, the terminal device obtains the configuration information of the SBFD and, based on the first indication information, learns the frequency domain location information of the DC component of the uplink transmission subband of the SBFD that needs to be reported. The terminal device can then send an RRC reconfiguration completion signaling to the access network device. The RRC reconfiguration completion signaling carries second indication information, which indicates the frequency domain location information of the DC component of the uplink transmission subband of the SBFD. Based on the second indication information, the access network device can determine the frequency domain location information of the DC component of the uplink transmission subband of the SBFD.

[0122] In one possible embodiment, the second indication information indicates the frequency domain location information of the DC component of the uplink transmission subband of the SBFD via cells dedicated to the uplink transmission subband of the SBFD.

[0123] For example, the second indication information could be SBFDUplinkTxDirectCurrentBWP, as described above in the information element description of SBFDUplinkTxDirectCurrentBWP, which will not be repeated here. The second indication information could also be an information element name other than SBFDUplinkTxDirectCurrentBWP, or SBFDUplinkTxDirectCurrentBWP could not include bwp-Id, or it could include other content.

[0124] In another possible embodiment, the second indication information can also indicate the frequency domain location information of the DC component of the uplink transport subband of the SBFD via existing cells dedicated to the BWP. For example, the second indication information can be UplinkTxDirectCurrentBWP. In this case, txDirectCurrentLocation in UplinkTxDirectCurrentBWP indicates the frequency domain location information of the DC component of the uplink transport subband of the SBFD.

[0125] (3) The uplink transmission subband of the SBFD is a part of the first BWP; if the frequency domain position information of the DC component of the first BWP is the same as the frequency domain position information of the DC component of the uplink transmission subband of the SBFD, the second indication information indicates the frequency domain position information of the DC component of the first BWP; if the frequency domain position information of the DC component of the first BWP is different from the frequency domain position information of the DC component of the uplink transmission subband of the SBFD, the second indication information indicates the frequency domain position information of the DC component of the uplink transmission subband of the SBFD.

[0126] For example, if BWP1 has an uplink and downlink bandwidth of 100MHz, and the uplink transmission subband of the SBFD configured by the access network equipment for the terminal equipment is located at 20MHz in the center of BWP1, the terminal equipment will find that the frequency domain position information of the DC component of BWP1 at 100MHz is the same as that of the DC component of the uplink transmission subband of SBFD. Therefore, when the access network equipment requests the reporting of the frequency domain position information of the DC component of the uplink transmission subband of SBFD, the terminal equipment can only report the frequency domain position information of the DC component of BWP1, that is, ignore the reporting of the frequency domain position information of the DC component of the uplink transmission subband of SBFD.

[0127] In one possible embodiment, if the frequency domain location information of the DC component of the first BWP is the same as the frequency domain location information of the DC component of the uplink transmission subband of the SBFD, the second indication information can indicate the frequency domain location information of the DC component of the first BWP through existing cells dedicated to BWP (such as UplinkTxDirectCurrentBWP).

[0128] In one possible embodiment, if the frequency domain location information of the DC component of the first BWP differs from the frequency domain location information of the DC component of the uplink transmission subband of the SBFD, the second indication information indicates the frequency domain location information of the DC component of the uplink transmission subband of the SBFD via a cell dedicated to the uplink transmission subband of the SBFD (such as SBFDUplinkTxDirectCurrentBWP). Alternatively, the second indication information indicates the frequency domain location information of the DC component of the uplink transmission subband of the SBFD via an existing cell dedicated to the BWP (such as UplinkTxDirectCurrentBWP).

[0129] It is evident that through implementation Figure 3 The described method enables the access network device to accurately determine the frequency domain location information of the DC component of the uplink transmission subband of SBFD based on the second indication information reported by the terminal device, thereby enabling resource scheduling and other operations to reduce the adverse impact of the DC component in the SBFD time slot on the transmission between the terminal device and the access network device.
