[0001] This application relates to the field of communication technology, and in particular to an SSB configuration method and communication device. Background Technology

[0002] New Radio (NR) communication systems support a discontinuous transmission (DTX) mechanism to reduce the power consumption of access network equipment. In the cell DTX mechanism, access network equipment can transmit channels / signals normally during the active duration of the cell DTX, and refrain from transmitting certain channels / signals during the inactive duration of the cell DTX, thereby reducing the power consumption of the access network equipment. How to further reduce the power consumption of access network equipment under the cell DTX mechanism is a pressing technical problem that needs to be solved. Summary of the Invention

[0003] This application provides an SSB configuration method and communication device, which helps to reduce the power consumption of access network equipment.

[0004] In a first aspect, embodiments of this application provide an SSB configuration method.

[0015] In one possible embodiment, the first SSB transmission configuration includes a first SSB transmission cycle configuration and / or a first SSB transmission pattern configuration, and the second SSB transmission configuration includes a second SSB transmission cycle configuration and / or a second SSB transmission pattern configuration.

[0016] In one possible embodiment, the first SSB is either a cell definition-synchronization signal block (CD-SSB) or a non-cell definition-synchronization signal block (NCD-SSB), and the second SSB is either a CD-SSB or an NCD-SSB.

[0040] To better understand the embodiments of this application, the system architecture involved in the embodiments of this application will be described first below:

[0041] Figure 1 This is a schematic diagram of the architecture of a communication system 10 provided in an embodiment of this application. For example... Figure 1 As shown, the communication system 10 includes a radio access network (RAN) 100, wherein the RAN 100 includes at least one RAN node (e.g., Figure 1 110a and 110b, collectively referred to as 110, may also include at least one terminal (such as...). Figure 1RAN100, denoted as RAN100, comprises RAN nodes 120a-120j, collectively referred to as RAN120. RAN100 may also include other RAN nodes, such as wireless relay equipment and / or wireless backhaul equipment. Figure 1 (Not shown in the diagram). Terminal 120 is wirelessly connected to RAN node 110. Terminals and RAN nodes can be interconnected via wired or wireless means. Communication system 10 may also include core network 200. RAN node 110 is connected to core network 200 via wireless or wired means. The core network equipment in core network 200 and RAN node 110 in RAN 100 can be independent physical devices, or they can be the same physical device integrating the logical functions of core network equipment and RAN node. Communication system 10 may also include data network (DN) 300.

[0042] RAN100 can be an evolved universal terrestrial radio access (E-UTRA) system, a new radio (NR) system, a 6th generation (6G) radio access system, or a future radio access system as defined in the 3rd generation partnership project (3GPP). RAN100 can also include two or more of the above-mentioned different radio access systems. RAN100 can also be an open RAN (O-RAN). RAN can also be referred to as an access network (AN).

[0043] RAN nodes, also known as radio access network equipment, RAN entities, or access nodes, are used to help terminals access communication systems wirelessly. In one application scenario, an RAN node can be a base station, an evolved NodeB (eNodeB), a transmission reception point (TRP), a next-generation NodeB (gNB) in 5G mobile communication systems, a next-generation base station in 6G mobile communication systems, or a base station in future mobile communication systems. RAN nodes can also be macro base stations (such as...) Figure 1 110a in the text), can also be a micro base station or an indoor station (such as... Figure 1 110b in the middle can also be a relay node or a donor node.

[0044] In another application scenario, multiple RAN nodes can collaborate to help terminals achieve wireless access, with different RAN nodes implementing different functions of the base station. For example, a RAN node can be a central unit (CU), a distributed unit (DU), or a radio unit (RU). Here, the CU performs the functions of the base station's Radio Resource Control (RRC) and Packet Data Convergence Protocol (PDCP), and can also perform the functions of the Service Data Adaptation Protocol (SDAP). The DU performs the functions of the base station's Radio Link Control (RANC) and Medium Access Control (MAC) layers, and can also perform some or all of the physical layer functions. For specific descriptions of these protocol layers, refer to the relevant 3GPP technical specifications. The RU can be used to implement radio frequency signal transmission and reception. The CU and DU can be two independent RAN nodes or integrated into the same RAN node, such as within a baseband unit (BBU). The RU can be included in radio frequency equipment, such as in a remote radio unit (RRU) or an active antenna unit (AAU). The CU can be further divided into two types of RAN nodes: CU-control plane and CU-user plane.

[0045] In different systems, RAN nodes may have different names. For example, in an O-RAN system, a CU can be called an open CU (O-CU), a DU can be called an open DU (O-DU), and an RU can be called an open RU (O-RU). The RAN nodes in the embodiments of this application can be implemented through software modules, hardware modules, or a combination of software and hardware modules. For example, a RAN node can be a server loaded with the corresponding software modules. The embodiments of this application do not limit the specific technology or device form used in the RAN nodes. For ease of description, a base station is used as an example of a RAN node in the following description.

[0046] A terminal is a device with wireless transceiver capabilities, capable of sending signals to or receiving signals from a base station. Terminals can also be called terminal equipment, user equipment (UE), mobile station, mobile terminal, etc. Terminals can be widely used in various scenarios, such as device-to-device (D2D), vehicle-to-everything (V2X) communication, machine-type communication (MTC), Internet of Things (IoT), virtual reality, augmented reality, industrial control, autonomous driving, telemedicine, smart grids, smart furniture, smart offices, smart wearables, smart transportation, smart cities, etc. Terminals can be mobile phones, tablets, computers with wireless transceiver capabilities, wearable devices, vehicles, airplanes, ships, robots, robotic arms, smart home devices, etc. The embodiments of this application do not limit the specific technology or device form used in the terminal.

[0047] Base stations and terminals can be fixed or mobile. They can be deployed on land, including indoors or outdoors, handheld or vehicle-mounted; they can also be deployed on water; and they can be deployed on aircraft, balloons, and satellites. The embodiments of this application do not limit the application scenarios of the base stations and terminals.

[0048] The roles of base stations and terminals can be relative, for example, Figure 1 The helicopter or drone 120i can be configured as a mobile base station. For terminals 120j accessing the wireless access network 100 via 120i, terminal 120i is a base station; however, for base station 110a, 120i is a terminal, meaning that 110a and 120i communicate via a wireless air interface protocol. Of course, 110a and 120i can also communicate via a base station-to-base station interface protocol; in this case, 120i is also a base station relative to 110a. Therefore, both base stations and terminals can be collectively referred to as communication devices. Figure 1 The 110a and 110b in the text can be referred to as communication devices with base station functions. Figure 1 The 120a-120j in the text can be referred to as communication devices with terminal functions.

[0049] Communication between base stations and terminals, between base stations, and between terminals can be conducted using licensed spectrum, unlicensed spectrum, or both simultaneously. Communication can be conducted using spectrum below 6 GHz, spectrum above 6 GHz, or both simultaneously. The embodiments of this application do not limit the spectrum resources used for wireless communication.

[0050] In the embodiments of this application, the functions of the base station can be executed by modules (such as chips) within the base station, or by a control subsystem that includes base station functions. This control subsystem, including base station functions, can be a control center in the aforementioned application scenarios such as smart grids, industrial control, intelligent transportation, and smart cities. Similarly, the functions of the terminal can be executed by modules (such as chips or modems) within the terminal, or by a device that includes terminal functions.

[0051] In this application, the base station sends downlink signals or downlink information to the terminal, with the downlink information carried on the downlink channel; the terminal sends uplink signals or uplink information to the base station, with the uplink information carried on the uplink channel. To communicate with the base station, the terminal needs to establish a radio connection on a cell controlled by the base station. The cell with which the terminal has established a radio connection is called the terminal's serving cell. When the terminal communicates with this serving cell, it is also susceptible to interference from signals from neighboring cells.

[0052] In the embodiments of this application, the time-domain symbol can be an orthogonal frequency division multiplexing (OFDM) symbol or a discrete Fourier transform-spread-OFDM (DFT-s-OFDM) symbol. Unless otherwise specified, the symbols in the embodiments of this application refer to time-domain symbols.

[0053] It is understood that in the embodiments of this application, PDSCH and PDCCH are just examples of downlink data channel and downlink control channel, respectively. In different systems and different scenarios, data channel and control channel may have different names, and the embodiments of this application do not limit this.

[0054] The following explanations of some terms used in the embodiments of this application are provided to facilitate understanding by those skilled in the art. These explanations are for illustrative purposes only and should not be construed as a disclosure or specific limitation of the technical solution of this application.

[0055] I. Synchronization Signal Block (SSB)

[0056] The synchronization signal block (SSB), also known as the synchronization signal and physical broadcast channel block, includes the primary synchronization signal (PSS), secondary synchronization signal (SSS), and physical broadcast channel (PBCH). As a terminal moves within the system, it continuously performs cell search and measurements based on the SSB to achieve initial access and mobility management. NR supports two types of SSBs: cell-defining SSB (CD-SSB) and non-cell-defining SSB (NCD-SSB).

[0057] The CD-SSB's PBCH carries the master information block (MIB). The MIB carries configuration information for the control-resource set (CORESET) 0 and configuration information for the listening timing of the type 0 physical downlink control channel common search space set (Type 0-PDCCH CSS). The main function of CORESET 0 is to define the time and frequency resources of the Type 0-PDCCH CSS and its listening timing. The terminal can search for the physical downlink control channel (PDCCH) based on CORESET 0 and Type 0-PDCCH CSS. This PDCCH is used to schedule the physical downlink shared channel (PDSCH) carrying the system information block 1 (SIB1). The terminal receives SIB1 based on the PDCCH, thereby obtaining the minimum system messages required to access the wireless network system. In other words, the CD-SSB can be used for random access by the terminal.

[0058] The NCD-SSB does not carry CORSET 0 configuration information; its primary purpose is radio resource management (RRM). Terminals can obtain RRM measurement results by measuring reference signals in the CD-SSB or NCD-SSB to support terminal mobility management. In other words, the CD-SSB can be used for both random access and RRM, while the NCD-SSB can be used for RRM.

[0059] II. Community DTX

[0060] In the cell DTX mechanism, access network devices can transmit channels / signals normally during the active duration of cell DTX, and refrain from transmitting certain channels / signals during the inactive duration of cell DTX to reduce the power consumption of the access network devices. For example, during the inactive period of cell DTX, access network devices may not transmit one or more of the following channels / signals: PDCCH, periodic channel state information reference signal (CSI-RS), semi-persistent CSI-RS, where the reported quantity in the CSI reporting configuration information associated with periodic or semi-persistent CSI-RS includes the rank indicator (RI), and semi-persistent PDSCH. For example, such as Figure 2 As shown, during the active duration of cell DTX, the access network device normally sends PDCCH at transmission times #1, #2, #5, and #6, and does not send PDCCH at transmission times #3, #4, and #7 during the inactive duration.

[0061] The activation duration can also be referred to as activation time, duration (on duration), etc., and the inactive time can also be referred to as inactive time, non-duration, etc. This application does not limit the names of activation duration and inactive duration. The cell DTX can also be referred to as the cell's DTX or other names, and this application does not limit the names in the embodiments.

[0062] III. Carrier Aggregation

[0063] NR employs carrier aggregation (CA) technology to increase the transmission bandwidth for individual users. Specifically, carrier aggregation integrates multi-frequency resources, combining spectrum resources in the same or different frequency bands for use by terminals, thereby improving overall network resource utilization and enhancing user experience. In general, CA can aggregate two or more component carriers (CCs) together to support greater transmission bandwidth.

[0064] For example, such as Figure 3 As shown, carrier frequencies F1 of cell 1, F2 of cell 2, and F3 of cell 3 are aggregated for use by the terminal. Cell 1 is the primary cell (PCell), and cells 2 and 3 are secondary cells (SCells). A PCell is the cell where the terminal establishes an initial connection, re-establishes an RRC connection, or is the primary cell designated during mobile handover. The carrier element corresponding to the PCell is called the primary component carrier (PCC).

[0065] An SCell is a cell added during RRC reconfiguration to provide additional radio resources. The carrier element corresponding to an SCell is called a secondary component carrier (SCC). It's important to note that primary and secondary cells are user-level concepts. A terminal's primary cell can be another terminal's primary or secondary cell, and a terminal's secondary cell can be another UE's primary or secondary cell.

[0066] IV. Serving Cell

[0067] For a terminal in connected state, if the terminal is not configured with a CA, it has only one serving cell. For a terminal in connected state, if the terminal is configured with a CA, both PCell and SCell belong to the terminal's serving cells.

[0068] V. Downlink control information (DCI)

[0069] The DCI is carried in the PDCCH. The DCI can be a cell-level DCI, indicating cell-level information. For example, a cell-level DCI can be scrambled using the System Information Radio Network Temporary Identifier (SI-RNTI), Paging Radio Network Temporary Identifier (P-RNTI), or Random Access Radio Network Temporary Identifier (RA-RNTI). Alternatively, the DCI can be a terminal-level DCI, indicating terminal-level information. For example, a terminal-level DCI can be scrambled using the Cell Radio Network Temporary Identifier (C-RNTI), Configured Scheduling Radio Network Temporary Identifier (CS-RNTI), or Semi-Persistent Channel State Information Radio Network Temporary Identifier (SP-CSI-RNTI).

[0070] VI. SSB Sudden Events

[0071] NR supports a wide range of carrier frequencies, but high-frequency carriers suffer from significant transmission loss, necessitating beamforming to increase the transmission distance of wireless signals. Since each beam covers a limited angle, NR uses beam scanning to cover the entire cell's service area. Beam scanning refers to transmitting physical channels or reference signals using beams from different directions at different times. A cell typically requires multiple SSBs to complete one beam scan. The SSBs required to complete one beam scan form an SSB burst set. For example, ... Figure 4 As shown, within one SSB cycle, the access network device can send multiple SSBs, and the multiple SSBs within one SSB cycle form an SSB burst set.

[0072] To further reduce the power consumption of access network devices, embodiments of this application provide an SSB configuration method and a communication device.

[0073] The SSB configuration method and communication device will be further described below with reference to the accompanying drawings. It is understood that this application uses a terminal and access network equipment as examples to illustrate the interaction, but this application does not limit the execution subject of the interaction. For example, the method executed by the terminal in this application can also be implemented by a communication / processing module in the terminal or a circuit or chip in the terminal responsible for communication / processing functions. Similarly, the method executed by the access network equipment in this application can also be implemented by a module (e.g., circuit, chip, or chip system) in the access network equipment, or a logic node, logic module, or software capable of implementing all or part of the functions of the access network equipment.

[0074] Please see Figure 5 , Figure 5 This is a flowchart illustrating an SSB configuration method provided in an embodiment of this application, wherein:

[0075] 501. The access network device sends a first signaling message to the terminal. This first signaling message is used to indicate the activation of DTX in the first cell, to indicate the use of a first SSB transmission configuration during the active duration of DTX in the first cell, and to indicate the use of a second SSB transmission configuration during the inactive duration of DTX in the first cell. Accordingly, the terminal can receive this first signaling message.

[0076] In this embodiment, the terminal can receive the first signaling in an RRC connected state. An RRC connected state means that an RRC connection has been established between the terminal and the access network equipment. The first cell can be any cell of the terminal. For example, the first cell can be a serving cell of the terminal.

[0077] In this embodiment of the application, the first signaling indicates that a first SSB transmission configuration is used during the active duration of the DTX in the first cell, and indicates that a second SSB transmission configuration is used during the inactive duration of the DTX in the first cell. That is, the first signaling can indicate different SSB transmission configurations for the active and inactive durations of the DTX in the first cell.

[0078] In one possible embodiment, the first SSB transmission configuration includes a first SSB transmission cycle configuration and / or a first SSB transmission pattern configuration. The second SSB transmission configuration includes a second SSB transmission cycle configuration and / or a second SSB transmission pattern configuration.

[0079] The SSB transmission period configuration is used to configure the transmission period of the SSB. For example, the SSB transmission period can be 2ms, 5ms, 10ms, or 20ms. Optionally, the SSB transmission period corresponding to the first SSB transmission period configuration is shorter than the SSB transmission period corresponding to the second SSB transmission period configuration, which helps to save power consumption of access network equipment.

[0080] For example, consider the first signaling instruction indicating different SSB cycle configurations for the active and inactive durations of the cell's DTX. Figure 6 As shown, the first signaling instruction activates the DTX of cell 1, and indicates that SSB transmission period configuration 1 is used during the active duration of the DTX of cell 1, and indicates that SSB transmission period configuration 2 is used during the inactive duration of the DTX of cell 1. The SSB transmission period corresponding to SSB transmission period configuration 1 is T1, and the SSB transmission period corresponding to SSB transmission period configuration 2 is T2, where T2 is greater than T1.

[0081] SSB transmission pattern configuration is used to configure the pattern of SSB transmission. The SSB transmission pattern is the distribution of SSBs within a period, that is, the distribution of SSBs in the SSB burst set within a period. Optionally, the number of SSBs in the SSB burst set corresponding to the first SSB transmission pattern configuration is greater than the number of SSBs in the SSB burst set corresponding to the second SSB transmission pattern configuration, which helps to save power consumption of access network equipment.

[0082] For example, consider the first signaling instruction indicating different SSB transmission pattern configurations for the active and inactive durations of the cell's DTX. Figure 7 As shown, the first signaling indicates that the DTX of cell 1 is activated, and indicates that SSB transmission pattern configuration 1 is used during the active duration of the DTX of cell 1, and indicates that SSB transmission pattern configuration 2 is used during the inactive duration of the DTX of cell 1. The SSB burst set corresponding to SSB transmission pattern configuration 1 includes 3 SSBs, and the SSB burst set corresponding to SSB transmission pattern configuration 2 includes 2 SSBs.

[0083] Optionally, multiple SSB transmission configurations corresponding to the first cell can be pre-configured on the terminal. For example, multiple SSB transmission configurations corresponding to the first cell can be pre-configured on the terminal via RRC signaling, or the protocol can pre-define multiple SSB transmission configurations corresponding to the first cell. Subsequent first signaling can indicate the first SSB transmission configuration by indicating the index of the first SSB transmission configuration, and the second SSB transmission configuration by indicating the index of the second SSB transmission configuration.

[0084] In one possible embodiment, the first signaling is further used to instruct the second cell not to activate DTX, and to instruct the second cell to adopt a third SSB transmission configuration. The third SSB transmission configuration may be the same as the first SSB transmission configuration or the second SSB transmission configuration, or it may be an SSB transmission configuration other than the first and second SSB transmission configurations.

[0085] In one possible embodiment, the first signaling can be radio resource control (RRC) signaling or DCI signaling. The following provides a detailed description of both cases where the first signaling is RRC signaling or DCI signaling:

[0086] I. The first signaling is RRC signaling.

[0087] When the first signaling is RRC signaling, it can indicate DTX activation and SSB transmission configuration for one or more cells of the terminal. These one or more cells can be the serving cells of the terminal. In the entirety of this application, indicating DTX activation for a cell means that the first signaling indicates whether DTX of the cell is activated. When the first signaling indicates that DTX of the cell is activated, indicating SSB transmission configuration for the cell means that the first signaling indicates the SSB transmission configuration used during the active duration of DTX of the cell, and indicates the SSB transmission configuration used during the inactive duration of DTX of the cell. Optionally, when the first signaling indicates that DTX of the cell is not activated, indicating SSB transmission configuration for the cell means that the first signaling indicates the SSB transmission configuration used by the cell.

[0088] For example, suppose the terminal has only one serving cell, which is cell 1. The first signaling instruction can provide DTX activation indication and SSB transmission configuration indication for cell 1.

[0089] For example, suppose the terminal is configured with CA and has two serving cells, PCell 1 and SCell 1. The first signaling can indicate DTX activation and SSB transmission configuration to PCell 1. Alternatively, the first signaling can indicate DTX activation and SSB transmission configuration to SCell 1. Or, the first signaling can indicate both DTX activation and SSB transmission configuration to PCell 1 and SCell 1.

[0090] Optionally, the first signaling may also indicate the DTX configuration of the one or more cells, such as a DTX pattern. That is, the first signaling can activate the DTX function of the cell when configuring the cell's DTX.

[0091] II. The first signaling is DCI

[0092] In one possible embodiment, the first signaling is terminal-level DCI, that is, the first signaling provides DTX activation indication and SSB transmission configuration indication to one or more cells of a terminal. The one or more cells can be the serving cells of the terminal.

[0093] For example, suppose the terminal has only one serving cell, which is cell 1. The first signaling instruction can provide DTX activation indication and SSB transmission configuration indication for cell 1.

[0094] For example, suppose the terminal is configured with CA and has two serving cells, PCell 1 and SCell 1. The first signaling can indicate DTX activation and SSB transmission configuration to PCell 1. Alternatively, the first signaling can indicate DTX activation and SSB transmission configuration to SCell 1. Or, the first signaling can indicate both DTX activation and SSB transmission configuration to PCell 1 and SCell 1.

[0095] In another possible embodiment, the first signaling is a cell-level DCI, meaning the first signaling provides a DTX activation indication and an SSB transmission configuration indication to one or more cells corresponding to one or more terminals. These one or more cells can be the serving cells of the one or more terminals. For example, the first signaling can be carried in a PDCCH within a common search space. In this way, one or more terminals can detect the first signaling by blindly checking the common search space.

[0096] For example, suppose terminal 1 has only one serving cell, which is cell 1. Terminal 2 also has only one serving cell, which is also cell 1. The first signaling instruction can provide DTX activation indication and SSB transmission configuration indication to cell 1.

[0097] For example, suppose terminal 1 has two serving cells, PCell 1 and SCell 1. Terminal 2 also has two serving cells, PCell 1 and SCell 1. The first signaling instruction can indicate DTX activation and SSB transmission configuration to PCell 1. Alternatively, the first signaling instruction can indicate DTX activation and SSB transmission configuration to SCell 1. Or, the first signaling instruction can indicate both DTX activation and SSB transmission configuration to PCell 1 and SCell 1.

[0098] For example, suppose terminal 1 has two serving cells, PCell 1 and SCell 1, and terminal 2 has two serving cells, PCell 1 and SCell 2. The first signaling instruction can indicate DTX activation and SSB transmission configuration to PCell 1. Alternatively, the first signaling instruction can indicate DTX activation and SSB transmission configuration to both PCell 1 and SCell 1. Or, the first signaling instruction can indicate DTX activation and SSB transmission configuration to both PCell 1 and SCell 2. Alternatively, the first signaling instruction can indicate DTX activation and SSB transmission configuration to both PCell 1 and SCell 2.

[0099] In this embodiment of the application, when the first signaling indicates DTX activation and SSB transmission configuration to multiple cells, the cell sending the first signaling can be PCell among the multiple cells, or any one of the multiple cells. This embodiment of the application does not limit this.

[0100] In one possible embodiment, the first signaling includes a first block and a second block. The first block is used to indicate the activation of DTX in the first cell, and to indicate the use of a first SSB transmission configuration during the active duration of DTX in the first cell, and to indicate the use of a second SSB transmission configuration during the inactive duration of DTX in the first cell. The second block is used to indicate DTX activation and SSB transmission configuration for the third cell. For example, if the second block indicates the activation of DTX in the third cell, then the second block also indicates the use of a third SSB transmission configuration during the active duration of DTX in the third cell, and indicates the use of a fourth SSB transmission configuration during the inactive duration of DTX in the third cell. If the second block indicates that DTX in the third cell is not activated, then the second block also indicates that the third cell uses a fifth SSB transmission configuration.

[0101] If the first signaling also provides DTX activation indication and SSB transmission configuration indication for more cells, the DCI can also include more blocks, with different blocks providing DTX activation indication and SSB transmission configuration indication for different cells. In this possible embodiment, providing DTX activation indication and SSB transmission configuration indication for different cells through different blocks allows for more flexible indication of DTX activation indication and SSB transmission configuration indication for different cells.

[0102] For example, suppose the first signaling instructs to activate DTX in cell 1 and instructs to use SSB transmission configuration 1 during the active duration of DTX in cell 1, and instructs to use SSB transmission configuration 2 during the inactive duration of DTX in cell 1. The first signaling also instructs to deactivate DTX in cell 2 and instructs cell 2 to use SSB transmission configuration 3. Figure 8 As shown, the first signaling includes two blocks: block 1 is used to give DTX activation indication and SSB transmission configuration indication to cell 1, and block 2 is used to give DTX activation indication and SSB transmission configuration indication to cell 2.

[0103] In one possible embodiment, the first block includes a first indication field and a second indication field. The first indication field is used to indicate the activation of DTX in the first cell, and the second indication field is used to indicate the use of a first SSB transmission configuration during the active duration of DTX in the first cell, and to indicate the use of a second SSB transmission configuration during the inactive duration of DTX in the first cell. Optionally, other blocks in the DCI may also include a first indication field and a second indication field, whereby the first indication field of a block is used to indicate DTX activation for the cell corresponding to the block, and the second indication field of a block is used to indicate SSB transmission configuration for the cell corresponding to the block. In this possible embodiment, using different indication fields to indicate DTX activation and SSB transmission configuration for the cell allows for more flexible indication of DTX activation and SSB transmission configuration for the cell.

[0104] For example, such as Figure 9 As shown, the first signaling includes two blocks. Block 1 includes a first indication field 1 and a second indication field 1. Block 2 includes a first indication field 2 and a second indication field 2. The first indication field 1 is used to indicate the activation of DTX in cell 1. The second indication field 1 is used to indicate the use of SSB transmission configuration 1 during the active duration of DTX in cell 1, and to indicate the use of SSB transmission configuration 2 during the inactive duration of DTX in cell 1. The first indication field 2 is used to indicate the inactive DTX in cell 2, and the second indication field 2 is used to indicate that cell 2 uses SSB transmission configuration 3.

[0105] Optionally, the second indication field in the first block includes a first subfield and a second subfield. The first subfield indicates that a first SSB transmission configuration is used during the active duration of DTX in the first cell, and the second subfield indicates that a second SSB transmission configuration is used during the inactive duration of DTX in the first cell. The number of bits in the first and second subfields can be the same, and the number of bits in the first and second subfields depends on the number of SSB transmission configuration types. For example, if the network side configures N SSB transmission configurations, then the number of bits in the first and second subfields is log2(N).

[0106] For example, suppose there are four SSB transmission configurations for the first cell: {SSB transmission configuration 1, SSB transmission configuration 2, SSB transmission configuration 3, and SSB transmission configuration 4}. The first subfield can include two bits. When the bit value of the first subfield is 00, it indicates that SSB transmission configuration 1 is used during the active duration of DTX in the first cell. When the bit value of the first subfield is 01, it indicates that SSB transmission configuration 2 is used during the active duration of DTX in the first cell. When the bit value of the first subfield is 10, it indicates that SSB transmission configuration 3 is used during the active duration of DTX in the first cell. When the bit value of the first subfield is 11, it indicates that SSB transmission configuration 4 is used during the active duration of DTX in the first cell. The indication method of the second subfield is similar and will not be elaborated here.

[0107] In another possible embodiment, the first block may also include only one indication field, which indicates both the activation of DTX in the first cell and the use of a first SSB transmission configuration during the active duration of DTX in the first cell, and the use of a second SSB transmission configuration during the inactive duration of DTX in the first cell. Optionally, other blocks in the first signaling may also include only one indication field, which indicates both DTX activation and SSB transmission configuration for the cell corresponding to the block.

[0108] In this embodiment, there are two possible implementations for how the terminal can accurately determine the bit position of the first block in the first signaling:

[0109] 1) The access network device may also send a third signaling message to the terminal, which indicates the start position of the first block in the first signaling message. Accordingly, the terminal may also receive the third signaling message.

[0110] The third signaling may include, but is not limited to, RRC signaling, MAC-CE signaling, etc. Optionally, the third signaling is sent through the first cell. Optionally, if the first signaling also provides DTX activation indication and SSB transmission configuration indication to other cells of the terminal, the access network device also sends signaling to the terminal through those other cells to indicate the start position of the block corresponding to those other cells in the first signaling, and the terminal can receive the signaling accordingly.

[0111] For example, such as Figure 8As shown, the first signaling includes two blocks. Block 1 is used to indicate DTX activation and SSB transmission configuration for cell 1, and block 2 is used to indicate DTX activation and SSB transmission configuration for cell 2. Cells 1 and 2 are both cells of terminal 1. The access network device can send RRC signaling 1 to terminal 1 through cell 1. RRC signaling 1 indicates that the start position of block 1 in the first signaling is bit 0. The access network device can send RRC signaling 2 to terminal 1 through cell 2. RRC signaling 2 indicates that the start position of block 2 in the first signaling is bit 30. Assuming a block has 30 bits, terminal 1 can determine that block 1 is located at bits 0 to 29 of the first signaling, and block 2 is located at bits 30 to 59 of the first signaling.

[0112] Optionally, if the number of bits in each block is not fixed, the third signaling may also indicate the number of bits in the first block. For example, RRC signaling 1 may also indicate that block 1 has 30 bits, and RRC signaling 2 may also indicate that block 3 has 30 bits. Alternatively, RRC signaling 1 may also indicate that block 1 has 10 bits, and RRC signaling 2 may also indicate that block 3 has 20 bits.

[0113] 2) The terminal sorts the blocks corresponding to the cell in ascending (or descending) order of the cell index. Based on the sorting result of the blocks corresponding to the cell and the number of bits in the blocks, the terminal can determine the bit position of the block corresponding to the cell in the first signaling.

[0114] For example, such as Figure 8 As shown, the first signaling includes two blocks: Block 1 is used to indicate DTX activation and SSB transmission configuration for cell 1, and Block 2 is used to indicate DTX activation and SSB transmission configuration for cell 2. Cells 1 and 2 are both cells of terminal 1. Terminal 1 sorts the blocks corresponding to the cells in ascending order of cell index. Based on the sorting result, terminal 1 determines that Block 1 corresponding to cell 1 precedes Block 2 corresponding to cell 2. Assuming a block has 30 bits, the terminal can determine that Block 1 is located in bits 0 to 29 of the first signaling, and Block 2 is located in bits 30 to 59 of the first signaling. Optionally, if the number of bits in each block is not fixed, the access network device can also indicate the number of bits in each block through signaling.

[0115] In one possible embodiment, the terminal may also send capability information to the access network device, indicating that the terminal supports different SSB transmission configurations during the active and inactive periods of the DTX. Correspondingly, the access network device may also receive this capability information. Based on this capability information, the access network device determines that the terminal supports different SSB transmission configurations during the active and inactive periods of the DTX. Subsequently, the access network device can instruct the terminal to use different SSB transmission configurations during the active and inactive periods based on the service status, thereby saving power consumption of the access network device.

[0116] 502. When the access network device is in the active duration of DTX in the first cell, it sends a first SSB corresponding to the first SSB transmission configuration in the first cell. Accordingly, when the terminal is in the active duration of DTX in the first cell, it can receive the first SSB in the first cell according to the first SSB transmission configuration.

[0117] 503. When the access network device is inactive during the DTX period of the first cell, it sends a second SSB corresponding to the second SSB transmission configuration in the first cell. Accordingly, when the terminal is inactive during the DTX period of the first cell, it receives the second SSB in the first cell according to the second SSB transmission configuration.

[0118] In one possible embodiment, the first SSB is either a CD-SSB or an NCD-SSB. The second SSB is either a CD-SSB or an NCD-SSB.

[0119] In one possible embodiment, the access network device may send a second signaling message to the terminal, the second signaling message indicating a first offset value and a second offset value, the first offset value being the offset between the transmission start time of the first SSB and the start time of the activation duration, and the second offset value being the offset between the transmission start time of the second SSB and the end time of the activation duration. Accordingly, the terminal may receive the second signaling message. Based on this possible embodiment, it is advantageous for the terminal to accurately determine the transmission start time of the first SSB and the second SSB.

[0120] The second signaling can be RRC signaling or other signaling, which is not limited in this embodiment. The second signaling can be sent through the first cell. Optionally, the transmission start time of the first SSB can be understood as the transmission start time of the SSB burst set corresponding to the first SSB transmission configuration, and the transmission start time of the second SSB can be understood as the transmission start time of the SSB burst set corresponding to the second SSB transmission configuration. Alternatively, the transmission start time of the first SSB can be understood as the transmission start time of the SSB corresponding to the first SSB transmission configuration, and the transmission start time of the second SSB can be understood as the transmission start time of the SSB corresponding to the second SSB transmission configuration. The transmission start time of the SSB burst set and the transmission start time of the SSB may be separated by X symbols, where X is an integer greater than or equal to 1.

[0121] Optionally, the first offset value and the second offset value are in units of symbols, meaning that the first offset value and the second offset value can be one or more symbols. Alternatively, the first offset value and the second offset value can also be in units of other time units, such as time slots. For example, such as... Figure 10 As shown, the start time of the activation duration of the first cell is time t1, the start time of the SSB burst set transmission corresponding to the first SSB transmission configuration is t2, and the start time of the SSB transmission corresponding to the first SSB transmission configuration is t3. The first offset value can be the time interval between t1 and t2, i.e., 3 symbols. Alternatively, the first offset value can be the time interval between t1 and t3, i.e., 5 symbols.

[0122] The activation duration of the first cell ends at time t4, the SSB burst set transmission start time corresponding to the second SSB transmission configuration starts at t5, and the SSB transmission start time corresponding to the second SSB transmission configuration starts at t6. The second offset value can be the time interval between t4 and t5, i.e., 5 symbols. Alternatively, the second offset value can be the time interval between t4 and t6, i.e., 7 symbols.

[0123] Optionally, the first offset value makes the transmission start time of the first SSB the start time of a certain frame, and the second offset value makes the transmission start time of the second SSB the start time of a certain frame.

[0124] Optionally, the DTX mentioned above can also be replaced with DRX.

[0125] It can be seen that, based on Figure 5 The described method allows access network devices to flexibly adopt different SSB transmission configurations during the active and inactive periods of DTX, based on service status. Compared to using a fixed SSB transmission configuration during the active and inactive periods of DTX, this method is more conducive to saving power consumption of access network devices.
