Technical Field

[0002] The present application relates to the field of communication technology, and in particular to a configuration method, device, and storage medium for wireless communication. Background Art

[0003] In some communication systems, base stations periodically transmit system information blocks (SIBs), such as SIB1, which wastes base station power. To reduce base station power consumption, base stations can transmit SIBs when there is communication demand within the covered cell, and not transmit SIBs when there is no communication demand within the cell. For example, a base station can transmit SIBs in response to requests from terminals within the covered cell. In this case, configuring terminals to request SIB transmissions from the base station is a pressing issue. Summary of the Invention

[0004] The embodiments of the present application provide a method, apparatus, and storage medium for configuring wireless communications, which reduce power consumption and processing delay of a terminal during a configuration process of requesting a base station to send an SIB.

[0005] In a first aspect, embodiments of the present application provide a method for configuring wireless communication. The method may be performed by a terminal device or a component (such as a chip or chip system) in the terminal device, or may be a logic module or software that implements all or part of the terminal device's functions. For ease of description, the following description uses the terminal device as the execution subject.

[0006] In this method, a terminal device receives a first SSB of a first cell, the first SSB carrying first indication information indicating the frequency domain position of a second SSB of a second cell, so that the terminal device receives the second SSB of the second cell according to the indicated frequency domain position, determines the identity of the second cell based on the second SSB, and then receives configuration information on the second cell. The configuration information is used to configure a first signal requesting the SIB of the first cell, thereby providing an effective configuration solution for the terminal device to request the SIB of the first cell. Furthermore, the problem of high power consumption and long processing delay caused by blind detection of the second SSB is avoided.

[0007] In a second aspect, embodiments of the present application provide a method, apparatus, and storage medium for configuring wireless communications. The method may be performed by a network device or a component (such as a chip or chip system) in the network device, or may be a logic module or software that implements all or part of the network device's functions. For ease of description, the following description will be based on the network device as the performing entity.

[0008] In one design, the network device may send a first SSB on a first cell, the first SSB carrying first indication information, the first indication information indicating the frequency domain position of a second SSB in a second cell, and send configuration information in the second cell, the configuration information being used to configure a first signal, the first signal requesting the SIB of the first cell.

[0009] In combination with the first aspect or the second aspect above, as an example, the first indication information received by the terminal device may indicate the frequency domain offset between the second SSB and the first SSB, and then the terminal device may determine the frequency domain position of the second SSB based on the frequency domain position of the first SSB and the frequency domain offset indicated by the first indication information. As another example, the first indication information received by the terminal device may indicate that the frequency domain offset between the second SSB and the first SSB is greater than a threshold, and then the terminal device may detect the SSB of the second cell within a frequency domain range exceeding the threshold to expand the indication range of the first indication information.

[0010] In combination with the first or second aspect above, exemplarily, the first indication information may include information of control resource set (CORESET) 0 and / or information of search space (SS) 0, and the information of CORESET 0 and / or SS0 is used to determine a target value, where the target value indicates a frequency domain offset. In this example, the information of CORESET 0 and / or SS0 is multiplexed to determine the target value for indicating the frequency domain offset, thereby indicating the frequency domain offset to save signaling overhead.

[0011] In combination with the first or second aspect above, illustratively, the first indication information may indicate that the frequency domain position of the second SSB is greater than the frequency domain position of the first SSB; or, the first indication information may indicate that the frequency domain position of the second SSB is less than the frequency domain position of the first SSB. On the one hand, the indication range of the first indication information is expanded; on the other hand, the terminal device detects the second SSB within the indicated range greater than or less than the frequency domain position of the first SSB, narrowing the range in which the terminal device detects the second SSB, thereby reducing power consumption and processing delay of the terminal device.

[0012] In combination with the first aspect or the second aspect above, exemplarily, the first indication information indicates a frequency domain range, and the frequency domain position of the second SSB is within the frequency domain range, indicating the terminal device to detect the range of the second SSB with a smaller signaling overhead, so as to reduce the power consumption and processing delay of the terminal device.

[0013] Exemplarily, the first SSB may also carry second indication information, where the second indication information indicates that the first SSB carries the first indication information, or the second indication information indicates that the first SSB can be used to indicate the frequency domain position of the second SSB of the second cell, so that the terminal device can successfully receive the first indication information.

[0014] In combination with the first or second aspect above, exemplarily, for frequency range (FR) 1, the bit length of the second indication information is 5 bits, of which 4 bits are carried in the subcarrier offset field, and the value of the second indication information is 30; or, for FR2, the second indication information is carried in the subcarrier offset field, the bit length of the second indication information is 4 bits, and the value of the second indication information is 14.

[0015] In combination with the above-mentioned first aspect or second aspect, exemplarily, the configuration information is carried in the SIB of the second cell.

[0016] In combination with the first or second aspect above, exemplarily, the configuration information includes the identifier of the first cell, and the identifier of the first cell is carried in SIB1, so that the terminal device can quickly determine whether the configuration information sent by the second cell is the configuration information corresponding to the first cell, that is, whether the configuration information is used to configure the first signal of the SIB requesting the first cell, thereby avoiding the terminal device receiving the configuration information that is not the configuration information corresponding to the first cell, thereby increasing the power consumption and processing delay of the terminal device.

[0017] In combination with the first aspect or the second aspect above, exemplarily, in order to facilitate the terminal device to receive the SIB of the first cell, such as SIB1, after requesting the SIB of the first cell, the configuration information of the second cell may include: CORESET0 and / or SS0 of the first cell; and / or, the offset between subcarrier 0 of the first SSB and subcarrier 0 of the common resource block (CRB).

[0018] In a third aspect, an embodiment of the present application provides a method for configuring wireless communication. The execution subject of this method is similar to the execution subject of the first aspect above, and will not be repeated for the sake of brevity.

[0019] The method includes: a terminal device receives a third SSB of a second cell, determines an identifier of the second cell based on the third SSB, and then receives configuration information of the second cell, where the configuration information is used to configure a first signal, the first signal is used to request the SIB of the first cell, the configuration information includes the identifier of the first cell, and the identifier of the first cell is carried in SIB1. This allows the terminal device to quickly determine whether the configuration information sent by the second cell is the configuration information corresponding to the first cell, that is, whether the configuration information is used to configure the first signal requesting the SIB of the first cell, thereby avoiding the terminal device receiving configuration information that is not the configuration information corresponding to the first cell, thereby avoiding an increase in power consumption and processing delay of the terminal device.

[0020] In a fourth aspect, an embodiment of the present application provides a method for configuring wireless communication. The execution subject of this method is similar to the execution subject of the second aspect above, and will not be repeated for the sake of brevity.

[0021] The method includes: the network device can send a third SSB in the second cell and send configuration information for configuring the first signal in the second cell, the first signal is used to request the SIB of the first cell, the configuration information includes the identifier of the first cell, and the identifier of the first cell is carried on SIB1.

[0022] In combination with the third aspect or the fourth aspect above, exemplarily, in order to facilitate the terminal device to receive the SIB of the first cell, such as SIB1, after requesting the SIB of the first cell, the configuration information of the second cell may include: CORESET0 and / or SS0 of the first cell; and / or, the offset between subcarrier 0 of the fourth SSB of the first cell and subcarrier 0 of the CRB.

[0039] The technical solution in this application will be described below with reference to the accompanying drawings.

[0040] Figure 1 is a schematic diagram of the architecture of a communication system 1000 provided in an embodiment of the present application. As shown in Figure 1, the communication system 1000 includes a radio access network (RAN) 100, wherein the RAN 100 includes at least one RAN node (such as 110a and 110b in Figure 1, collectively referred to as 110), and may also include at least one terminal (such as 120a-120j in Figure 1, collectively referred to as 120). The RAN 100 may also include other RAN nodes, such as wireless relay devices and / or wireless backhaul devices (not shown in Figure 1). The terminal 120 is connected to the RAN node 110 via a wireless connection. Terminals and RAN nodes can be connected to each other via wired or wireless connections. The communication system 1000 may also include a core network 200. The RAN node 110 is connected to the core network 200 via a wireless or wired connection. The core network devices in the core network 200 and the RAN nodes 110 in the RAN 100 may be independent and different physical devices, or may be the same physical device that integrates the logical functions of the core network devices and the logical functions of the RAN nodes.

[0041] RAN100 can be an evolved universal terrestrial radio access (E-UTRA) system, a new radio (NR) system, a sixth generation (6G) radio access system, or a future radio access system defined in the 3rd Generation Partnership Project (3GPP), or a WiFi system. RAN100 can also include two or more of the aforementioned different radio access systems. RAN100 can also be an open RAN (O-RAN).

[0042] A RAN node, also known as a radio access network device, RAN entity, or access node, facilitates wireless access to a communication system by a terminal. In one application scenario, a RAN node can be a base station, an evolved NodeB (eNodeB), a transmission reception point (TRP), a next-generation NodeB (gNB) in a fifth-generation (5G) mobile communication system, a next-generation base station in a sixth-generation (6G) mobile communication system, a base station in a future mobile communication system, or an access node in a WiFi system. A RAN node can be a macro base station (such as 110a in Figure 1), a micro base station, an indoor station (such as 110b in Figure 1), a relay node, or a donor node.

[0043] In another application scenario, multiple RAN nodes can collaborate to help terminals achieve wireless access, with different RAN nodes implementing portions of the base station's functions. For example, a RAN node can be a centralized unit (CU), a distributed unit (DU), or a radio unit (RU). The CU implements the base station's radio resource control protocol and packet data convergence protocol (PDCP) functions, as well as the service data adaptation protocol (SDAP) functions. The DU implements the base station's radio link control layer and medium access control (MAC) layer functions, as well as some or all of the physical layer functions. For detailed descriptions of each of the above protocol layers, please refer to the relevant 3GPP technical specifications. The RU can be used to implement the transmission and reception of radio frequency signals. The CU and DU can be two independent RAN nodes, or they can be integrated into the same RAN node, such as in a baseband unit (BBU). The RU can be included in radio frequency equipment, such as 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.

[0044] In different systems, RAN nodes may have different names. For example, in an O-RAN system, a CU may be called an open CU (O-CU), a DU may be called an open DU (O-DU), and a RU may be called an open RU (O-RU). The RAN node in the embodiments of the present application may be implemented by a software module, a hardware module, or a combination of a software module and a hardware module. For example, the RAN node may be a server loaded with the corresponding software module. The embodiments of the present application do not limit the specific technology and specific device form adopted by the RAN node. For ease of description, the following description takes a base station as an example of a RAN node.

[0045] A terminal is a device with wireless transceiver capabilities that can send signals to a base station or receive signals from a base station. A terminal may also be referred to as a terminal device, 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 grid, smart furniture, smart office, smart wearable, smart transportation, smart city, etc. A terminal can be a mobile phone, tablet computer, computer with wireless transceiver capabilities, wearable device, vehicle, airplane, ship, robot, robotic arm, smart home device, etc. The embodiments of this application do not limit the specific technology and specific device form adopted by the terminal.

[0046] Base stations and terminals can be fixed or mobile. They can be deployed on land, indoors or outdoors, handheld or vehicle-mounted; on water; or on aircraft, balloons, and satellites. The embodiments of this application do not limit the application scenarios of base stations and terminals.

[0047] The roles of base stations and terminals can be relative. For example, the helicopter or drone 120i in Figure 1 can be configured as a mobile base station. To terminals 120j accessing the wireless access network 100 via 120i, terminal 120i is a base station. However, to base station 110a, 120i is a terminal, meaning that communication between 110a and 120i occurs via a wireless air interface protocol. Of course, communication between 110a and 120i can also occur via a base station-to-base station interface protocol. In this case, 120i is also a base station relative to 110a. Therefore, base stations and terminals can be collectively referred to as communication devices. 110a and 110b in Figure 1 can be referred to as communication devices with base station functionality, while 120a-120j in Figure 1 can be referred to as communication devices with terminal functionality.

[0048] Communication between base stations and terminals, between base stations, and between terminals can be carried out through authorized spectrum, unauthorized spectrum, or both; communication can be carried out through spectrum below 6 gigahertz (GHz), spectrum above 6 GHz, or spectrum below 6 GHz and spectrum above 6 GHz. The embodiments of the present application do not limit the spectrum resources used for wireless communication.

[0049] In the embodiments of the present application, the functions of the base station may also be performed by a module (such as a chip) in the base station, or by a control subsystem that includes the base station functions. The control subsystem that includes the base station functions here may be a control center in the above-mentioned application scenarios such as smart grid, industrial control, smart transportation, and smart city. The functions of the terminal may also be performed by a module (such as a chip or modem) in the terminal, or by a device that includes the terminal functions.

[0050] In this application, a base station sends downlink signals or downlink information to a terminal, and the downlink information is carried on a downlink channel; the terminal sends uplink signals or uplink information to the base station, and the uplink information is carried on an uplink channel. In order to communicate with the base station, the terminal needs to establish a wireless connection with the cell controlled by the base station. The cell with which the terminal has established a wireless connection is called the serving cell of the terminal. When the terminal communicates with the serving cell, it will also be interfered with by signals from neighboring cells.

[0051] To facilitate understanding of the embodiments of the present application, the technical terms related to the present application are explained below.

[0052] 1. Master Information Block (MIB): includes the status information of whether access to the cell is prohibited, and further receives the physical layer information of the SIB.

[0053] The bits in the MIB (for example, the MIB is the A bit, including a0, a1, ..., a A-1 ) and an additional 7 bits (e.g., a A ,a A+1 ,…,a A+7 ) are mapped to physical resources through physical layer operations to form the physical broadcast channel (PBCH), which, together with the synchronization signal, forms the synchronization signal and PBCH block (SSB), also known as the synchronization signal block. Physical layer operations include but are not limited to scrambling, channel coding, rate matching, and modulation.

[0054] The MIB may include the SSB subcarrier offset (ssb-SubcarrierOffset) field and the physical downlink control channel (PDCCH) configuration system message 1 (pdcch-ConfigSIB1) field. The information carried by the ssb-SubcarrierOffset field is used to indicate the offset between subcarrier 0 of the SSB and subcarrier 0 of the CRB (such as subcarrier offset), that is, k SSB The pdcch-ConfigSIB1 field may include: CORESET0 fields, such as the controlResourceSetZero field, and SS0 fields, such as the searchSpaceZero field. In FR1 (e.g., 410MHz-7125MHz), the information carried by the ssb-SubcarrierOffset field in the MIB may be used together with one of the extra 7 bits mapped to form the PBCH to indicate k. SSB In FR2 (such as 24250MHz ~ 52600MHz), the information carried by the ssb-SubcarrierOffset field in the MIB can indicate k SSB .

[0055] k SSB The instructions may include the following options.

[0056] Solution 1: For FR1 (e.g., 410MHz-7125MHz), 0≤k SSB ≤23. For FR2 (such as 24250MHz~52600MHz), 0≤k SSB≤11. In this case, the CORESET0 corresponding to the SSB exists, that is, the SSB is associated with SIB1. In this case, the SSB is called a cell-defining SSB (CD SSB). Furthermore, pdcch-ConfigSIB1 can configure CORESET0 and SS0. The terminal can receive the PDCCH scheduling SIB1 in CORESET0 and SS0, and thus receive SIB1.

[0057] Solution 2: For FR1, 24 ≤ k SSB ≤29. For FR2, 12≤k SSB ≤13. In this case, the CORESET 0 corresponding to the SSB does not exist. In this case, the SSB is a non-cell-defining SSB (NCD SSB). In this case, the pdcch-ConfigSIB1 field indicates the global synchronization channel number (GSCN) offset. A CD SSB may exist at the frequency domain location of the GSCN offset.

[0058] In the above solution 2, for FR1, k SSB The mapping relationship between the controlResourceSetZero field and the searchSpaceZero field and the offset of GSCN can be seen in the following Table 1.

[0059] Table 1

[0060] In the above scheme 2, for FR2, k SSB , controlResourceSetZero field and searchSpaceZero field and GSCN offset The mapping relationship between them can be seen in Table 2 below.

[0061] Table 2

[0062] Solution 3: Targeting FR1,k SSB =30. For FR2,k SSB =14. In this case, CORESET 0 corresponding to the SSB does not exist. In this case, the SSB is an NCD-SSB. In this case, pdcch-ConfigSIB1 is a reserved and unused field.

[0063] Solution 4: Targeting FR1,k SSB =31. For FR2,k SSB=15. In this case, the CORESET 0 corresponding to the SSB does not exist. In this case, the SSB is an NCD-SSB. In this case, pdcch-ConfigSIB1 refers to the range of the GSCN, and there is no CD-SSB in this range.

[0064] 2. GSCN: GSCN indicates the frequency domain position SSRef of the SSB, as shown in Tables 3 and 4 below. SSRef can be understood as a synchronization raster.

[0065] Table 3

[0066] Table 4

[0067] Currently, in some communication systems, such as 5G mobile communication systems, base stations always periodically send SIBs, such as SIB1, resulting in high power consumption of the base station. Therefore, it is considered that the base station can send SIB1 when there is a communication demand in the cell it covers, and not send SIB1 when there is no communication demand in the cell, so as to reduce the power consumption of the base station. The cell covered by the base station that sends SIB1 on demand can be called an energy-saving cell or a network energy saving (NES) cell. Based on this, a terminal in an idle or inactive state can blindly detect SSBs, obtain cell information (such as cell ID) based on the detected SSBs, and determine whether the cell is an NES cell. If the cell is an NES cell, the terminal can send an uplink wake-up signal (UL-WUS) to the base station of the NES cell to request the base station to send SIB1. The UL-WUS can be configured by the base station of another cell (such as cell A), or in other words, the terminal can send a UL-WUS to the NES cell based on the configuration information of the other cell (such as cell A). In this case, the terminal blindly detects the SSB of the cell, then receives the corresponding SIB based on the SSB, and determines whether the SIB carries the configuration information for configuring UL-WUS. This configuration scheme will increase the processing delay and power consumption of the terminal.

[0068] To address the above technical issues, embodiments of the present application propose a configuration solution in which the base station of an NES cell indicates the frequency domain location of the SSB of cell A to a terminal, enabling the terminal to receive configuration information from cell A and, based on the configuration information, request the NES cell to transmit an SIB. This solution provides an effective solution for configuring a terminal to request the base station to transmit an SIB. Furthermore, during the configuration process of requesting the base station to transmit an SIB, the terminal ensures low power consumption and processing latency.

[0069] It should be noted that UL-WUS is only an exemplary name and is not limited in this application. For example, it can be any type of uplink signaling or data.

[0070] In the embodiment of the present application, the network device may be, for example, the RAN 110 shown in FIG. 1 , and the terminal device may be, for example, the terminal 120 shown in FIG. 1 . The present application does not specifically limit the types of the network device and the terminal device.

[0071] In addition, terminal devices and network devices can be hardware devices, or software functions running on dedicated hardware, software functions running on general-purpose hardware, such as virtualization functions instantiated on a platform (for example, a cloud platform), or entities including dedicated or general-purpose hardware devices and software functions. This application does not limit the specific form of terminal devices and network devices.

[0072] In the embodiments of the present application, the network device sends an SSB, which can be expressed as the network device broadcasting an SSB; similarly, the network device sends an SIB, which can be expressed as the network device broadcasting an SIB. When the two expressions are used interchangeably, the meanings expressed are the same.

[0073] The method provided by the present application will be described in detail below with reference to the accompanying drawings. In the following embodiments, the configuration of wireless communication implemented by interaction between a terminal device, a first network device, and a second network device is used as an example. The first cell covered by the first network device may be the aforementioned NES cell, and the second cell covered by the second network device may be the aforementioned cell A. It should be understood that the present application is not limited to this and, for example, may also be applied to uplink and downlink measurement processes.

[0074] The first network device and the second network device may be the same network device or different network devices, which is not limited in this application.

[0075] It should also be understood that the above-mentioned terminal device can be replaced by a component configured in the terminal device (such as a chip, a chip system, a processor, etc.), or a logic module or software that can realize all or part of the functions of the terminal device; the above-mentioned network device can also be replaced by a component configured in the network device (such as a chip, a chip system, a processor, etc.), or a logic module or software that can realize all or part of the functions of the network device.

[0076] Figure 2 is a schematic flow chart of a wireless communication configuration method 200 provided in an embodiment of the present application. As shown in Figure 2, method 200 may include some or all of steps 210 to 240. Each step in method 200 is described in detail below.

[0077] S210: A first network device sends a first SSB in a first cell. Correspondingly, a terminal device receives the first SSB in the first cell.

[0078] S220: The second network device sends a second SSB in the second cell. Correspondingly, the terminal device receives the second SSB from the second network device.

[0079] S230, the terminal device determines an identifier of the second cell based on the second SSB;

[0080] S240: The second network device sends configuration information in the second cell. Correspondingly, the terminal device receives the configuration information in the second cell. The configuration information is used to configure a first signal, and the first signal is used to request an SIB for the first cell.

[0081] In the above S210, the first network device may broadcast a first SSB in the first cell; the terminal device may receive the first SSB broadcast by the first network device, for example, by detecting the first SSB through blind SSB detection. The first SSB carries first indication information, which indicates the frequency domain location of the second SSB of the second cell, so that the terminal device can receive the second SSB of the second cell based on the indicated frequency domain location. Optionally, the first SSB may also include an identifier of the first cell.

[0082] It should be understood that the present application does not limit the number of first cells, that is, the network device of each first cell in multiple first cells can send an SSB carrying the first indication information, and then the terminal device can determine the frequency domain position of the second SSB based on the SSB of each first cell. The second SSB indicated by the SSBs of different first cells can be the same second cell or different second cells, and this application does not limit this.

[0083] This application does not limit the manner in which the first indication information indicates the frequency domain position of the second SSB. The following are some possible examples provided in the embodiments of this application:

[0084] Example 1: The first indication information indicates the frequency domain offset between the second SSB and the first SSB. The frequency domain position of the first SSB can be obtained by the terminal device detecting the first SSB, and then the terminal device can determine the frequency domain position of the second SSB based on the frequency domain position of the first SSB and the frequency domain offset indicated by the first indication information.

[0085] The frequency domain offset can be the offset of the GSCN between the second SSB and the first SSB. Because the frequency domain position of the SSB can be determined according to the GSCN, the frequency domain offset between the second SSB and the first SSB can be determined. However, this application is not limited to this. For example, the frequency domain offset can be the frequency difference between the second SSB and the first SSB, the subcarrier offset, etc. For ease of understanding, the frequency domain offset is used below. Take the example for explanation. Optionally, the frequency domain offset may be the absolute value of the frequency domain offset of the second SSB relative to the first SSB; or the frequency domain offset may include an offset direction. When the frequency domain offset includes an offset direction, the frequency domain offset may be a positive value, a negative value, or zero, that is, the frequency domain offset of the second SSB relative to the first SSB may be a positive value, a negative value, or zero. For example, a positive frequency domain offset indicates that the frequency of the second SSB is higher than that of the first SSB, and a negative frequency domain offset indicates that the frequency of the second SSB is lower than that of the first SSB.

[0086] Optionally, when the frequency domain offset is a positive value, it may be referred to as a positive offset, and when the frequency domain offset is a negative value, it may be referred to as a negative offset.

[0087] For example, the GSCN of the SSB of the second cell is in, is the GSCN of the SSB of the first cell detected by the terminal device (i.e. the GSCN of the first SSB), For GSCN interval, in FR1 or FR2-1 (24250MHz-52600MHz), FR2-2 (52600MHz-71000MHz),

[0088] Referring to Figure 3, cell B and cell C can both be the first cell. The first indication information carried in the first SSB sent by cell B indicates the GSCN offset between the second SSB and the first SSB. For FR1, determine the GSCN of the SSB of the second cell, such as cell A1, as The GSCN offset between the second SSB and the first SSB indicated by the first indication information carried in the first SSB sent by cell C For FR1, determine the GSCN of the SSB of the second cell, such as cell A2, as It is understandable that in Figure 3, the GSCNs may be equally spaced, but in the frequency domain, the SS Ref The intervals may not be equal.

[0089] In one implementation of Example 1 above, the value of the bit in the first indication information can be used to determine a target value, which is used to indicate the frequency domain offset. Exemplarily, the first indication information may include CORESET0 information and / or SS0 information, where the CORESET0 information may be the controlResourceSetZero field described above, and the SS0 information may be the searchSpaceZero field described above. The target value may be determined based on 16×controlResourceSetZero+searchSpaceZero.

[0090] For FR1, 16×controlResourceSetZero+searchSpaceZero and the indicated The corresponding relationship between them can be seen in Table 5 below:

[0091] Table 5

[0092] For example, when the target value is 0, When the target value is 1, ...When the target value is 255,

[0093] For FR2, 16×controlResourceSetZero+searchSpaceZero and the indicated The corresponding relationship between them is similar and will not be described again for the sake of brevity.

[0094] In the second implementation of the above example 1, the bits in the first indication information can directly indicate the frequency domain frequency shift between the second SSB and the first SSB. For example, when the bits in the first indication information are 0000, it indicates that the frequency domain frequency shift between the second SSB and the first SSB is 0000. When the bits in the first indication information are 0001, it indicates that the second SSB is equal to the first SSB. Etc., the present application does not limit the number of bits of the first indication information. For example, the first indication information may include information of CORESET0 or information of SS0. For example, the first indication information includes information of CORESET0. For FR1, the information of CORESET0 is the same as the indicated information. The corresponding relationship between them can be seen in Table 6 below:

[0095] Table 6

[0096] For example, when the value of controlResourceSetZero is 0, When the value of controlResourceSetZero is 1, ...When the value of controlResourceSetZero is 15,

[0097] For FR2, controlResourceSetZero is the same as the indicated The corresponding relationship between them is similar and will not be described again for the sake of brevity.

[0098] In any implementation of the above example 1, the first indication information is limited by the number of bits and indicates a limited number of frequency domain offsets. On this basis, in order to expand the indication range of the first indication information, the first indication information can indicate that the frequency domain offset is greater than the threshold, such as indicating out of range. The first indication information indicates that the frequency domain offset is greater than the threshold, which can include that the second SSB is higher in frequency than the first SSB and the offset exceeds the first threshold. The value of the first threshold can be greater than or equal to 0. The offset exceeding the first threshold can be understood as the value of the offset being greater than the first threshold. It can also include that the second SSB is lower in frequency than the first SSB and the offset exceeds the second threshold. The offset exceeding the second threshold can be understood as the value of the offset being less than the second threshold. The value of the second threshold can be less than or equal to 0. It should be noted that the first threshold and the second threshold respectively constrain the offset in the positive and negative directions, and the first threshold and the second threshold can be the same or different.

[0099] Combined with the first implementation of the above example 1, for FR1, 16×controlResourceSetZero+searchSpaceZero and the indicated The corresponding relationship between them can be seen in Table 7 below:

[0100] Table 7

[0101] For example, when the target value is 255, the first indication information indicates It is out of range, that is, the first indication information indicates that the difference between the GSCN of the second SSB and the GSCN of the first SSB is greater than or equal to 128, or the difference between the GSCN of the second SSB and the GSCN of the first SSB is less than or equal to -129.

[0102] Combined with the second implementation of the above example 1, for FR1, the information of CORESET0 and the indicated The corresponding relationship between them can be seen in Table 8 below:

[0103] Table 8

[0104] For example, when the value of controlResourceSetZero is 15, the first indication information indicates It is out of range, that is, the first indication information indicates that the difference between the GSCN of the second SSB and the GSCN of the first SSB is greater than or equal to 8, or the difference between the GSCN of the second SSB and the GSCN of the first SSB is less than or equal to -9.

[0105] Exemplarily, when the first indication information indicates that the frequency domain offset is out of range, the terminal device can detect the SSB of the second cell within the frequency domain range that exceeds the threshold.

[0106] Example 2: The first indication information indicates that the frequency domain position of the second SSB is greater than the frequency domain position of the first SSB; alternatively, the first indication information indicates that the frequency domain position of the second SSB is less than the frequency domain position of the first SSB. In Example 2, the range indicated by the first indication information is larger, and by indicating that the frequency domain position of the second SSB is greater than or less than the frequency domain position of the first SSB, the range in which the terminal device can detect the SSB is narrowed, thereby reducing the power consumption of the terminal device.

[0107] In one implementation of the above-mentioned Example 2, the first indication information may include 1 bit. When the bit is 0, it may indicate that the frequency domain position of the second SSB is greater than the frequency domain position of the first SSB, and when the bit is 1, it may indicate that the frequency domain position of the second SSB is less than the frequency domain position of the first SSB; or, when the bit is 1, it may indicate that the frequency domain position of the second SSB is greater than the frequency domain position of the first SSB, and when the bit is 0, it may indicate that the frequency domain position of the second SSB is less than the frequency domain position of the first SSB. Of course, this application does not limit the number of bits and values ​​of the first indication information in Example 2.

[0108] Example 3: The first indication information indicates a frequency domain range, and the frequency domain position of the second SSB is within the frequency domain range. As an example, the first indication information may indicate the starting frequency domain position and / or ending frequency domain position of the frequency domain range; as another example, the first indication information may indicate an identifier of a frequency domain range from a plurality of pre-divided frequency domain ranges, and the frequency domain range includes the frequency domain position of the second SSB.

[0109] As an implementation method of the above example three, the frequency domain range can be obtained based on the division of GSCN. Taking the GSCN of the first SSB as a reference, each frequency domain range can be regarded as a GSCN group, and each GSCN group includes at least one GSCN (for example, including M GSCNs, M is a positive integer). For example, GSCN from arrive As a group, is a GSCN group. Similarly, For another GSCN group, For another GSCN group, and so on. For a GSCN group, For another GSCN group, For another GSCN group, and so on. As shown in FIG4 , each GSCN group includes three GSCNs. Taking the GSCN group 1 indicated by the first indication information as an example, the first indication information can indicate the identifier of the GSCN group 1, such as “1”, or the first indication information can indicate the starting GSCN of the GSCN group 1 (such as ) and the end GSCN of GSCN group 1 (such as ), or the first indication information may indicate the offset of the starting GSCN (e.g., +1) and the offset of the ending GSCN (e.g., +3) of GSCN group 1. The value of the bit in the first indication information may be used to determine a target value, which is used to indicate the GSCN group.

[0110] This application does not limit the granularity of frequency range or GSCN division. The granularity of frequency range or GSCN division can be preset, agreed upon by a protocol, or indicated by the first network device, and this application does not limit this. Optionally, the granularity of frequency range or GSCN division can be associated with the bandwidth. For example, the value of M is related to the bandwidth.

[0111] The first indication information may also include an additional 7-bit information a in the PBCH A ,a A+1 ,…,a A+7 The first indication information may also include one or more bits in the MIB.

[0112] In some embodiments, the first SSB may also carry second indication information, and the second indication information indicates that the first SSB carries the first indication information, or the second indication information indicates that the first SSB can be used to indicate the frequency domain position of the second SSB of the second cell. Exemplarily, when the first indication information includes CORESET0 information and / or SS0 information, since the multiplexing controlResourceSetZero field and searchSpaceZero field indicate the frequency domain offset, in order to facilitate the terminal device to identify that the controlResourceSetZero field and searchSpaceZero field in the SSB indicate the offset of the GSCN of the second SSB. Exemplarily, for FR1, the second indication information may indicate the offset (such as subcarrier offset) between subcarrier 0 of the first SSB and subcarrier 0 of the CRB, that is, k SSB , is 30, or it can be understood that the second indication information is k SSB , the value of the second indication information is 30, as shown in Table 9 below; for FR2, the second indication information may indicate k SSB is 14, or it can be understood that the second indication information is k SSB , the value of the second indication information is 14, as shown in Table 10 below.

[0113] Table 9

[0114] Table 10

[0115] When the first indication information includes one of the information of CORESET0 or SS0, the above-mentioned example of the second indication information is also applicable. Taking the first indication information including the information of CORESET0 as an example, see the following Table 11. For FR1, the second indication information may refer to, k SSB is 30.

[0116] Table 11

[0117] As mentioned above, for FR1, the information carried by the ssb-SubcarrierOffset field in the MIB can be used together with one of the additional 7 bits in the PBCH to indicate k SSB In FR2, the information carried by the ssb-SubcarrierOffset field in the MIB can indicate k SSB . Exemplarily, for FR1, the second indication information may include 5 bits, of which 4 bits are carried in the subcarrier offset field. For FR2, the second indication information may be carried in the subcarrier offset field, and the subcarrier offset field may be, for example, the above-mentioned ssb-SubcarrierOffset field.

[0118] It should be understood that this application does not limit the range of the frequency domain offset between the second SSB and the first SSB indicated by the first indication information. In addition to the above examples, the first indication information can also indicate a larger range of frequency domain offsets (including negative offsets and positive offsets) so that the second cell can use a larger GSCN range.

[0119] For example, for FR1, 16×controlResourceSetZero+searchSpaceZero and the indicated The corresponding relationship between them can be seen in Table 12 below. The absolute value of is greater than or equal to 769. Optionally, for FR1, The absolute value of is less than or equal to 896.

[0120] Table 12

[0121] For example, when the target value is 0, When the target value is 1, ...When the target value is 255,

[0122] Optionally, at least one bit or at least one code point in the first indication information may be one or more reserved bits, as shown in Table 13 and Table 14 below:

[0123] Table 13

[0124] Table 14

[0125] This application does not limit the use and function of reserved. As an example, reserved can indicate that the GSCN is out of range. For example, in Table 13 above, when the target value is 255, it can indicate that the GSCN is out of range, that is, the frequency domain offset between the second SSB and the first SSB is not within the range of -769 to -896 and 769 to 895. For example, in Table 14 above, when the target value is 254 or 255, it can indicate that the GSCN is out of range. For example, when the target value is 254, it indicates that the frequency domain offset between the second SSB and the first SSB exceeds the third threshold. The third threshold may be a negative value, such as -895 or -769 in Table 14. The frequency domain offset exceeding the third threshold can be understood as the value of the frequency domain offset being less than -895 or greater than -769. When the target value is 255, it indicates that the frequency domain offset between the second SSB and the first SSB exceeds the fourth threshold. The fourth threshold may be a positive value, such as 895 or 769 in Table 14. The frequency domain offset exceeding the fourth threshold can be understood as the value of the frequency domain offset being greater than 895 or less than 769. As another example, reserved can be understood as not indicating the frequency domain position of the second SSB.

[0126] For example, for FR2, 16×controlResourceSetZero+searchSpaceZero is the same as the indicated The corresponding relationship between them can be seen in Table 15 below. The absolute value of is greater than or equal to 257. Optionally, for FR2, The absolute value of is less than or equal to 384.

[0127] Table 15

[0128] For example, when the target value is 0, When the target value is 1, ...When the target value is 255,

[0129] For FR2, the specific implementation method when the first indication information indicates one or more reserved bits (reserved) is similar to the above-mentioned example related to FR1 and will not be repeated for the sake of brevity.

[0130] In some embodiments, the first indication information may indicate whether the second SSB is within the GSCN range. For example, the GSCN range may be: in, Can be indicated by the controlResourceSetZero field, This can be indicated by the searchSpaceZero field.

[0131] In some embodiments, the first indication information may indicate the frequency band of the second cell, such as the frequency band number. Optionally, some or all bits in the first indication information may be used to indicate the frequency band of the second cell. For example, for FR1, the correspondence between 16×controlResourceSetZero+searchSpaceZero and the frequency band number of the indicated second cell may be shown in Table 16 below:

[0132] Table 16

[0133] For example, when the target value is 0, the band number is 1; when the target value is 1, the band number is 2; ..., when the target value is 255, the band number is 256. For FR2, the correspondence between 16×controlResourceSetZero+searchSpaceZero and the indicated band number is similar and will not be repeated for brevity.

[0134] Optionally, the first indication information may indicate the frequency band of the second cell through some bits, and indicate the frequency domain offset between the second SSB and the first SSB through another part of the bits. For example, the frequency band of the second cell may be indicated through controlResourceSetZero, and the offset between the second SSB and the first SSB may be indicated through searchSpaceZero; or the frequency band information of the second cell may be indicated through searchSpaceZero, and the offset between the second SSB and the first SSB may be indicated through controlResourceSetZero.

[0135] Optionally, the first indication information may indicate whether the frequency band of the second cell is the same as the frequency band of the first cell, or the first indication information may indicate the offset between the frequency band of the second cell and the frequency band of the first cell, such as the difference between the channel number of the second cell and the frequency band number of the first cell.

[0136] In the above S220, the terminal device may receive the second SSB sent by the second network device based on the frequency domain position of the second SSB indicated by the first indication information. The second SSB may carry the identifier of the second cell. Further, in S230, the terminal device may determine the identifier of the second cell based on the second SSB, such as by the terminal device receiving the second SSB to obtain the identifier of the second cell. Then, in S240, the terminal device may receive the configuration information sent by the second network device in the second cell.

[0137] Exemplarily, the configuration information may include an identifier of the first cell (such as a cell ID), time-frequency resources, a transmission period, power, and the like of the first signal.

[0138] In some embodiments of the above S240, the configuration information may be carried by the SIB of the second cell. For example, the configuration information may be carried in any one or more SIBs. When the configuration information is carried in multiple SIBs, different SIBs may carry the same configuration information, or different SIBs may respectively carry some bits in the configuration information. The SIBs may include: SIB1 to SIB8 and any SIBs not defined in the future, which may be collectively referred to as SIBx. Therefore, the terminal device may receive the SIB sent by the second network device and obtain the configuration information. For example, when the configuration information is carried in SIB1 and SIB2, the terminal device may receive SIB1 according to CORESET0 indicated by the second SSB, and then may receive SIB2.

[0139] In some embodiments, in order to facilitate the terminal device to receive the SIB of the first cell, such as SIB1, after requesting the SIB of the first cell, the second cell may indicate, through configuration information, the relevant parameters of receiving the SIB of the first cell. In particular, when the controlResourceSetZero field and the searchSpaceZero field in the first SSB are used to indicate the frequency domain position of the second SSB, the terminal device may receive the SIB of the first cell based on the relevant parameters of the SIB indicated in the configuration information. Exemplarily, the configuration information may include but is not limited to at least one of the following:

[0140] CORESET0 of the first cell;

[0141] SS0 of the first cell;

[0142] The offset between subcarrier 0 of the first SSB and subcarrier 0 of the CRB.

[0143] Therefore, in an embodiment of the present application, by carrying the first indication information in the first SSB sent by the first network device, the first indication information indicates the frequency domain position of the second SSB of the second cell, so that the terminal device receives the second SSB of the second cell at the indicated frequency domain position, and determines the identity of the second cell based on the second SSB, and then receives the configuration information in the second cell, the configuration information is used to configure the first signal requesting the SIB of the first cell, and provides an effective configuration scheme for the terminal device to request the first network device to send the SIB. Furthermore, based on the frequency domain position of the second SSB of the second cell indicated by the first indication information, the second SSB is received, and the configuration information of the second cell is further received, thereby avoiding the problems of high power consumption and long processing delay caused by blind detection of the second SSB.

[0144] Figure 5 is a schematic flow chart of another wireless communication configuration method 300 provided in an embodiment of the present application. As shown in Figure 5, the method 300 may include some or all of the following steps S310 to S330.

[0145] S310: The second network device sends a third SSB in the second cell. Correspondingly, the terminal device receives the third SSB of the second cell.

[0146] S320, the terminal device determines an identifier of the second cell based on the third SSB;

[0147] S330: The second network device sends configuration information in the second cell. Correspondingly, the terminal device receives the configuration information in the second cell.

[0148] The configuration information is used to configure a first signal, and the first signal is used to request the SIB of the first cell.

[0149] In the above S310, the second network device may broadcast the third SSB in the second cell. As a first example, the terminal device may receive the third SSB through blind detection; as a second example, the terminal device may receive the third SSB based on the frequency domain position of the third SSB indicated by the first network device. In the above second example, the implementation method of the frequency domain position of the third SSB indicated by the first network device can refer to the relevant description in the embodiment shown in Figure 2. In this case, the third SSB may be the second SSB in the above embodiment. The above two examples are only examples and non-restrictive descriptions. For example, the terminal device may also receive the third SSB based on the identifier of the second cell agreed upon in the protocol.

[0150] The above S320 has the same or similar implementation as S230 in Figure 2, and will not be described again for the sake of brevity.

[0151] In the above S330, the configuration information can be carried by the SIB of the second cell. In order to enable the terminal device to quickly determine whether the configuration information sent by the second cell is the configuration information corresponding to the first cell, that is, whether the configuration information is used to configure the first signal of the SIB requesting the first cell, to avoid the configuration information received by the terminal device not being the configuration information corresponding to the first cell and increasing the power consumption and processing delay of the terminal device. In an embodiment of the present application, part of the configuration information can be carried in SIB1, and the remaining part of the information can be carried in the SIB message after SIB1. The information carried in SIB1 can be used to determine whether the configuration information is the configuration information corresponding to the first cell. This application does not limit the carrying method of the remaining part of the information. For example, the remaining part of the information can be carried in one or more SIBs, and the remaining part of the information can also be carried in SIB1. In this way, the terminal device determines that the configuration information is the configuration information corresponding to the first cell based on the received SIB1, and then continues to receive the configuration information carried in the subsequent SIB. Based on the received SIB1, it determines that the configuration information is not the configuration information corresponding to the first cell, and then continues to try to receive the configuration information corresponding to the first cell on other cells.

[0152] Exemplarily, the information carried in SIB1 in the configuration information may be the identifier of the first cell, or may be the frequency of the first SSB, or other information that can identify that the configuration information corresponds to the first cell. This application does not limit this.

[0153] In some embodiments, the second network device can send or broadcast configuration information corresponding to different cells in the second cell (such as cell A). Referring to Table 17 below, the second network device can carry multiple cell identifiers (such as cell ID 1, cell ID 2, ...) in the SIB1 broadcast by the second cell; the second network device can carry the remaining part of the configuration information in the SIBx broadcast by the second cell (here SIBx can be understood as other SIBs other than SIB1), such as the configuration information indicated by cell ID 1 (excluding cell ID 1), the configuration information indicated by cell ID2 (excluding cell ID 2), etc. This application does not limit the remaining part of the configuration information carried in SIBx. For example, the second network device can also carry all the configuration information in the SIBx broadcast by the second cell, such as the configuration information indicated by cell ID 1 (including cell ID 1), the configuration information indicated by cell ID 2 (including cell ID 2), etc.

[0154] Table 17

[0155] In some embodiments, in order to facilitate the terminal device to receive the SIB of the first cell, such as SIB1, after requesting the SIB of the first cell, the second cell may indicate, through configuration information, the relevant parameters of the SIB of the first cell, and the terminal device may receive the SIB based on the relevant parameters of the SIB of the first cell indicated in the configuration information. Exemplarily, the configuration information may include, but is not limited to, at least one of the following:

[0156] CORESET0 of the first cell;

[0157] SS0 of the first cell;

[0158] The offset between subcarrier 0 of the fourth SSB of the first cell and subcarrier 0 of the CRB.

[0159] The fourth SSB may be sent by the first network device in the first cell. It should be understood that when the embodiment shown in FIG5 is combined with the embodiment shown in FIG2, the fourth SSB may be the first SSB in the embodiment shown in FIG2.

[0160] Therefore, in an embodiment of the present application, part of the configuration information is carried in SIB1, and the remaining part of the information is carried in the SIB message after SIB1. The information carried in SIB1 can be used to determine whether the configuration information is the configuration information corresponding to the first cell. The terminal device can quickly determine whether the configuration information sent by the second cell is the configuration information corresponding to the first cell, that is, whether the configuration information is used to configure the first signal of the SIB requesting the first cell, thereby avoiding the configuration information received by the terminal device not being the configuration information corresponding to the first cell, thereby avoiding the increase of power consumption and processing delay of the terminal device.

[0161] It is understood that, in order to implement the functions in the above embodiments, the base station and the terminal include hardware structures and / or software modules corresponding to the execution of each function. Those skilled in the art should readily appreciate that, in conjunction with the units and method steps of the various examples described in the embodiments disclosed in this application, this application can be implemented in the form of hardware or a combination of hardware and computer software.
