For example, the UE can act as a scheduling entity that provides sidelink signals between UEs in V2X or D2D, etc. For example, a cellular phone and a car communicate with each other using a sidelink signal. The cellular phone and the smart home device communicate with each other without relaying the communication signal through the base station.

[0028] The network device in the embodiment of the present application may be a device for communicating with a terminal device, and the network device may also be referred to as an access network device or a wireless access network device, such as a base station. The network device in the embodiment of the present application may refer to a wireless access network (RAN) node (or device) that connects a terminal device to a wireless network. Base station can broadly cover various names as follows, or replace with the following names, such as: NodeB, evolved NodeB (eNB), next generation NodeB (gNB), relay station, access point, transmission point (TRP), transmission point (TP), master station MeNB, auxiliary station SeNB, multi-standard radio (MSR) node, home base station, network controller, access node, wireless node, access point (AP), transmission node, transceiver node, base band unit (BBU), remote radio unit (RRU), active antenna unit (AAU), remote radio head (RRH), central unit (CU), distributed unit (DU), positioning node, etc. The base station can be a macro base station, a micro base station, a relay node, a donor node or the like, or a combination thereof. The base station can also refer to a communication module, a modem or a chip used to be arranged in the aforementioned device or apparatus. The base station can also be a mobile switching center and a device that performs base station functions in device-to-device D2D, vehicle-to-everything (V2X), machine-to-machine (M2M) communications, a network-side device in a 6G network, and a device that performs base station functions in future communication systems. The base station can support networks with the same or different access technologies. The embodiments of the present application do not limit the specific technology and specific device form used by the network equipment.

[0029] Base stations can be fixed or mobile. For example, a helicopter or drone can be configured to act as a mobile base station, and one or more cells can move based on the location of the mobile base station. In other examples, a helicopter or drone can be configured to act as a device that communicates with another base station.

[0030] In some deployments, the network device in the embodiments of the present application may refer to a CU or a DU, or the network device includes a CU and a DU. The gNB may also include an AAU.

[0031] The network equipment and terminal equipment can be deployed on land, including indoors or outdoors, handheld or vehicle-mounted; they can also be deployed on the water surface; they can also be deployed on aircraft, balloons and satellites in the air. The embodiments of the present application do not limit the scenarios in which the network equipment and terminal equipment are located.

[0032] It should be understood that all or part of the functions of the communication device in the present application may also be implemented by software functions running on hardware, or by virtualization functions instantiated on a platform (eg, a cloud platform).

[0033] With the development of mobile communication technology, communication systems adopt large-scale multiple-input multiple-output (MIMO) technology, non-orthogonal multiple access technology, simultaneous full-duplex communication technology, new modulation technology, new coding technology, high-order modulation and other technologies, which can achieve peak rates of up to Gbit / s to meet the transmission of large amounts of data such as high-definition video and virtual reality; the air interface delay level needs to be around 1ms to meet real-time applications such as autonomous driving and telemedicine. Ultra-large network capacity provides connection capabilities for hundreds of billions of devices to meet the communication of the Internet of Things. Spectral efficiency is more than 10 times higher than that of previous communication systems. Under continuous wide-area coverage and high mobility, the user experience rate reaches 100Mbit / s. Traffic density and connection density are greatly improved. The system collaboration and intelligence level are improved, which is manifested in the collaborative networking of multiple users, multiple points, multiple antennas, and multiple ingestion, as well as flexible and automatic adjustment between networks.

[0034] The system messages of the communication system can be divided into master information block (MIB) messages and some system information blocks (SIB) messages. MIB messages are always sent on the broadcast channel (BCH) with a period of 80ms and are repeated within 80ms. MIB messages also include parameters required to obtain SIB1 messages from the cell. SIB1 includes information about the availability and scheduling of other SIBs. Other SIB messages are provided through periodic broadcasts or on demand. If other SIBs are provided on demand, SIB1 includes information for the terminal device to perform system information (SI) requests; SIBs other than SIB1 are included in SI messages, which are transmitted on the downlink shared channel (DL-SCH). Each SI message is periodically transmitted within a time domain window (called SI window); SIB1 is sent on DL-SCH with a period of 160ms and a variable transmission repetition period within 160ms. The default transmission repetition period of SIB1 is 20ms, but the actual transmission repetition period depends on the network implementation. SIB1 carries the most critical information required for the terminal device to access the cell, such as random access parameters. SIB1 includes information about the availability and scheduling of other SIBs. For example, SIB1 includes mappings of other SIBs to SI messages, periods, and SI window sizes. SIB1 also indicates whether one or more SIBs are provided only on demand, in which case it can also provide the physical random access channel (PRACH) configuration required by the terminal device to request the required SI message. SIB1 also contains radio resource configuration information common to all terminal devices and cell prohibition information applied to unified access control. SIBs other than SIB1 are carried in SI messages, which are transmitted on DL-SCH. Only SIBs with the same periodicity can be mapped to the same SI message. Each SI message is sent within a time domain window that occurs periodically (called an SI window in which all SI messages have the same length). Each SI message is associated with an SI window, and the SI windows of different SI messages do not overlap. That is, only the corresponding SI message is sent within an SI window. SI messages can be sent multiple times within an SI window.

[0035] As mentioned above, in a traditional communication system, a network device periodically transmits SIB1. For a terminal device, it cannot be guaranteed that each transmitted SIB1 is effectively utilized, which may result in a waste of energy and resources.

[0036] For example, the access network equipment in the communication system periodically sends SIB1 for the initial access of the terminal device and schedules other SIBs required by the terminal device in the idle / inactive mode. However, even if there is no demand from the terminal device, or no terminal device (e.g., UE) resides on the cell, the access network equipment always transmits SIB1. This scheme of periodically transmitting SIB1 may cause the access network equipment (e.g., base station) to consume relatively high power, resulting in a waste of energy. At the same time, each transmitted SIB1 may not be effectively utilized, resulting in a waste of transmission resources.

[0037] In view of the above problems, in order to save power consumption of access network equipment, SIB1 needs to be optimized. Some known solutions propose that the terminal device can trigger the transmission of SIB1 based on a request (hereinafter referred to as the "first request"), that is, the terminal device can trigger the transmission of SIB1 through the first request based on its own needs. For example, if a terminal device in idle / inactive mode needs SIB1, the terminal device can send a first request to the network device to trigger the transmission of SIB1. On the contrary, if the terminal device in idle / inactive mode does not need SIB1, the terminal device may not send the first request to the network device. In some scenarios, this SIB1 transmission method can also be called on-demand transmission of SIB1. Compared with the periodic transmission of SIB1 in the traditional solution, this on-demand transmission of SIB1 helps to reduce unnecessary SIB1 transmission and associated PRACH monitoring, thereby providing network devices with more opportunities to be in sleep mode. However, how to implement the sending of the first request is an urgent problem to be solved.

[0038] In order to solve the above problems, an embodiment of the present application provides a method for wireless communication, in which a terminal device receives first information sent by a network device, and the first information is used to determine whether the first cell supports transmission of on-demand SIB1 and / or transmission of related configuration information of the first request (for example, the transmission resources of the first request and / or the sequence information of the first request). Compared with the periodically transmitted SIB1 in the traditional scheme, the terminal device can determine whether it is necessary to send a first request in the first cell to trigger the transmission of SIB1, and how to send the first request in the first cell, which helps to reduce unnecessary SIB1 transmissions to improve energy and resource utilization.

[0039] Combined with the following Figure 2 A wireless communication method according to an embodiment of the present application is introduced. Figure 2 It is a schematic flowchart of the wireless communication method of an embodiment of the present application. Figure 2 The method shown includes step S210.

[0040] In step S210, the network device sends first information to the terminal device.

[0041] In some implementations, the first information is used to determine whether the first cell supports transmission of the target SIB1, and the transmission of the target SIB1 is triggered based on a request from a terminal device. The transmission of the target SIB1 is triggered based on a request from a terminal device, so the target SIB1 is also the on-demand SIB1 mentioned above, and may also be referred to as "OD-SIB1 (on demand SIB1)".

[0042] Since the transmission target SIB1 helps to improve the utilization of energy and resources, in some implementations, if the first cell supports the transmission target SIB1, the first cell can also be called a network energy saving (NES) cell, that is, the target SIB1 comes from the NES cell.

[0043] In some implementations, a terminal device that supports triggering SIB1 based on a request of the terminal device is also referred to as a terminal device with NES capability.

[0044] In some implementations, a terminal device that does not support triggering of SIB1 based on a request of the terminal device is also referred to as a terminal device without NES capability or a legacy terminal device.

[0045] In some implementations, the first information is used to determine whether the first cell supports the transmission target SIB1. It can be understood that the first information is used to determine whether the first cell is a NES cell.

[0046] In some other implementations, the first information is used to determine a transmission resource of the first request and / or sequence information of the first request.

[0047] In some implementations, the first request is used to request the target SIB1 of the first cell, or the first request is used to request the network device of the first cell to send the target SIB1, or the target SIB1 of the first cell is triggered based on the first request. For example, the synchronization signal broadcast channel block (synchronization signal block / physical broadcast channel block, SS / PBCH block, SSB) sent by the first cell does not carry SIB1, and the terminal device in the idle / inactive state can send a first request to the first cell to request the first cell to send the target SIB1 to access the first cell.

[0048] In the embodiment of the present application, the first request is not limited. For example, the first request may be an uplink wake up signal (UL WUS), which is used to wake up the network device in the uplink so that it can send the target SIB1 at an appropriate time. For another example, the first request may be "on demand information or signaling".

[0049] In the embodiments of the present application, there is no limitation on the transmission resources. In some implementations, the transmission resources may include one or more of the following: time domain resources, frequency domain resources, and code domain resources. Taking the transmission resources including time domain resources as an example, the time domain resources may include symbols, time slots, subframes, frames, etc. Of course, in the embodiments of the present application, the transmission resources may also include other time domain resources introduced in future communication systems. Taking the transmission resources including frequency domain resources as an example, the frequency domain resources may include subcarriers, frequency bands, bandwidths, etc. Of course, in the embodiments of the present application, the frequency domain resources may also include other frequency domain resources introduced in future communication systems. Taking the transmission resources including code domain resources as an example, the code domain resources may include codebooks, codewords, etc. Of course, in the embodiments of the present application, the code domain resources may also include other code domain resources introduced in future communication systems.

[0050] The following describes the related schemes of the first information of the embodiments of the present application in combination with Embodiment 1 and Embodiment 2.

[0051] Embodiment 1: The first information is used to determine whether the first cell supports transmission target SIB1.

[0052] In some implementations, if the first information is used to determine whether the first cell supports transmission of the target SIB1, the first information includes a first parameter and / or configuration information.

[0053] In some implementations, the first parameter is carried in a field of a physical broadcast channel (PBCH) of the first cell, that is, the first parameter is carried on a PBCH payload of the first cell. For example, the terminal device can obtain the first parameter from the PBCH payload, and the first parameter is used to indicate the identity information of the first cell (such as information used to determine whether the first cell supports the transmission of the target SIB1). Both the terminal device with NES capability and the terminal device without NES capability can detect the SSB of the first cell and obtain the PBCH, thereby obtaining the first parameter.

[0054] In some implementations, the first parameter is carried in the MIB of the first cell, that is, the first parameter is carried on the MIB of the PBCH of the first cell.

[0055] In some implementations, the first parameter is carried in a spare bit of the MIB of the first cell. For example, the first parameter can be carried in a spare bit of the MIB that is not used by other functions, and these spare bits can be redefined or expanded to indicate whether the first cell supports the transmission target SIB1. Through this method, it is convenient for each terminal device that receives the SSB of the first cell to determine whether the first cell is an NES cell, which can provide the terminal device with a rapid identification capability and help reduce signaling overhead.

[0056] In some other implementations, the first parameter is carried in an existing field of the MIB of the first cell. For example, the first parameter is carried in a parameter SSB-SubcarrierOffset of the MIB of the first cell.

[0057] In some implementations, if the first parameter is carried in an existing field of the MIB of the first cell, the first parameter can be used to indicate the frequency domain offset between the transmission resource of the SSB and the reference resource. For example, the first parameter is Kssb, and the reference resource is Kssb is used to determine the transmission resources and The frequency domain offset between Kssb and SSB-SubcarrierOffset is carried by the parameter SSB-SubcarrierOffset of the MIB of the first cell. Of course, in the embodiment of the present application, the first parameter can also be used to indicate other information.

[0058] In some implementations, the first information includes only the first parameter, and the first parameter can be used to indicate whether the first cell supports the transmission target SIB1. For example, the first parameter is Kssb, which is a part of the SSB identification and can be used to indicate whether the first cell supports the transmission target SIB1. In this way, the terminal device can determine whether the first cell supports the transmission target SIB1 without receiving SIB1.

[0059] In some implementations, the value of the first parameter may be one or more predefined or preconfigured values. For example, when the first parameter is Kssb, and the value of Kssb included in the first information based on the protocol definition is one or more invalid values, it indicates that the first cell supports the transmission target SIB1.

[0060] In some implementations, the first parameter is Kssb, and the value of the first parameter can be a reserved value of Kssb. For example, frequency range (FR) 1 and FR2 each have a reserved Kssb value, which is not used for conventional SSB transmission, but is specifically used to indicate whether the first cell supports the transmission target SIB1. Therefore, the reserved Kssb value can be used to indicate that the first cell is a NES cell that supports the transmission target SIB1. For another example, for FR1, when the value of Kssb is 30, it indicates that the first cell supports the transmission target SIB1; for FR2, when the value of Kssb is 14, it indicates that the first cell supports the transmission target SIB1.

[0061] In some implementations, the first parameter is Kssb, and the value of the first parameter may be a valid value of Kssb. For example, the valid value of Kssb for FR1 is 0 to 23, and the valid value of Kssb for FR2 is 0 to 11. In the traditional solution, the terminal device may determine from the MIB whether there is a control resource set (CORESET) for a common search space (CSS) set of a type 0 physical downlink control channel (PDCCH) according to the valid value of Kssb. In an embodiment of the present application, the existing valid value of Kssb may be reinterpreted to indicate whether the first cell supports the transmission target SIB1. For another example, for FR1, the protocol defines that if the value of Kssb is one or more values ​​in the range of 0 to 23, such as 12, 18, it may indicate that the first cell supports the transmission target SIB1; for FR2, the protocol defines that if the value of Kssb is one or more values ​​in the range of 0 to 11, such as 3, 5, it may indicate that the first cell supports the transmission target SIB1.

[0062] In some implementations, the first parameter is Kssb, and the value of the first parameter may be an invalid value of Kssb. For example, the invalid value of Kssb for FR1 is 24 to 31, and the invalid value of Kssb for FR2 is 12 to 15. The invalid value of Kssb is not used and may be used to indicate whether the first cell supports the transmission target SIB1. For another example, for FR1, the protocol defines that if the value of Kssb is one or more values ​​from 24 to 31, such as 25, 28, it may indicate that the first cell supports the transmission target SIB1. For FR2, the protocol defines that if the value of Kssb is one or more values ​​from 12 to 15, such as 13, 14, it may indicate that the first cell supports the transmission target SIB1.

[0063] In some implementations, the configuration information in the above text is used to configure the first request. For example, the first request is ULWUS, the configuration information is UL WUS configuration information, and the UL WUS configuration information is used to configure UL WUS.

[0064] In some implementations, the configuration information is associated with one or more first cells, that is, the first request corresponding to the one or more first cells can be configured based on the configuration information.

[0065] In the embodiment of the present application, there is no limitation on the manner in which the terminal device receives the configuration information. In some implementations, the configuration information is received by the terminal device in the anchor cell. For example, the configuration information is associated with one or more first cells, an anchor cell can manage one or more first cells, and the anchor cell can have the same DU as one or more first cells. An anchor cell can send configuration information to terminal devices residing or connected in one or more first cells associated with the configuration information. This configuration information requires the anchor cell to coordinate between one or more first cells to ensure effective transmission and reception of signals. Since changes in SIB1 may occur periodically, synchronization is required between one or more first cells and the anchor cell, and a fallback procedure can be formulated to ensure rapid and reliable recovery from failures. At this time, the configuration information received by the terminal device residing in or having accessed the first cell includes the configuration information corresponding to the first cell in which it resides and / or the configuration information corresponding to other first cells. In other implementations, the configuration information is received by the terminal device in the first cell. For example, the configuration information is associated with a first cell. The configuration information is relatively simple, but the signal transmission and resource allocation in the first cell still need to be considered. When the terminal device resides in or is connected to the first cell associated with the configuration information, the configuration information can be received. At this time, the configuration information received by the terminal device only includes the configuration information corresponding to the first cell where it resides or is connected.

[0066] In some implementations, if the configuration information is received by the terminal device in the first cell, the presence of the configuration information is an implicit indication that the target SIB1 can be requested in the first cell. That is, if the terminal device receives the configuration information in the first cell, it can be determined that the first cell supports the transmission of the target SIB1.

[0067] In some implementations, the configuration information is associated with one or more first cells, which can be understood as the configuration information being associated with the physical cell identifier (PCI) of one or more first cells and / or the frequency information of one or more first cells, that is, based on the PCI of the first cell and / or the frequency information of one or more first cells, it can be determined whether the first cell supports the transmission target SIB1. For example, when a terminal device with NES capability resides in cell A, the PCI of one or more first cells associated with the configuration information can obtain the PCI of cell A by detecting the SSB of cell A. If the PCI of cell A is associated with the configuration information, the terminal device can determine that cell A supports the transmission target SIB1.

[0068] In some implementations, the configuration information is sent in one or more of the following ways: periodic broadcast; carried in downlink control information (DCI); carried in a physical downlink shared channel (PDSCH); carried in SIB.

[0069] In some implementations, the configuration information is sent in a manner including periodic broadcasting. It can be understood that the anchor cell can serve as a master cell, responsible for uniformly periodically broadcasting configuration information associated with one or more first cells. Accordingly, terminal devices residing in or having accessed one or more first cells can receive the periodically broadcast configuration information.

[0070] In some implementations, in order to maximize energy conservation, the configuration information broadcast period can be a long period, that is, greater than 20ms. This long-period configuration information broadcast mode is also called "sparse mode". For example, see Figure 3 , SSB is broadcast once every 20ms, configuration information is broadcast once every 80ms, and the network equipment of the anchor cell broadcasts configuration information in SFN0, SFN8, SFN16, SFN24, and SFN32 in the system frame number (SFN) 0 to 38.

[0071] In some implementations, the configuration information is sent in a manner including being carried in DCI, which can be understood as the configuration information being carried in a new DCI format. For example, since the maximum interleaver input is 164 bits, 24 bits are reserved for a cyclic redundancy check (CRC), so the DCI payload size is limited to 140 bits, and a new DCI format with a payload size of 140 bits is used to carry the configuration information.

[0072] In some implementations, the configuration information is sent in a manner including being carried in DCI, which can be understood as the configuration information being carried in an existing DCI format. For example, using the remaining reserved bits on DCI_1_0 to carry a CORESET of a PDCCH with configuration information, the CORESET can be easily multiplexed on the same timeslot carrying an SSB.

[0073] In some implementations, the configuration information is sent by carrying it on a PDSCH. It can be understood that if the data required to be transmitted by the configuration information exceeds 140 bits, the PDSCH can be used to carry the configuration information.

[0074] In some implementations, the configuration information may be sent in a manner including being carried in a SIB, that is, the configuration information is carried in the SIB.

[0075] In some implementations, the configuration information is carried in the SIB, which can be understood as the configuration information being carried in the existing SIB of the anchor cell. For example, the configuration information is carried in the SIB of the anchor cell (such as SIB1, SIB2, etc.).

[0076] In some implementations, the configuration information is carried in the SIB, which can be understood as the configuration information being carried in a newly added SIB of the anchor cell.

[0077] In some implementations, the configuration information may be sent in other broadcast messages carried by the anchor cell. For example, the configuration information is carried in the SSB of the anchor cell.

[0078] In some implementations, the configuration information can be frequency-division multiplexed with SSB. Figure 3, SSB is broadcast every 20ms, configuration information is broadcast every 80ms, and configuration information and SSB are frequency-division multiplexed on SFN0, SFN8, SFN16, SFN24, and SFN32 in SFN0 to 38. For another example, the configuration information is carried on PDSCH. Assuming that the bandwidth of the initial bandwidth part (BWP) is 48 resource blocks (RBs), SSB occupies 20 RBs for synchronization signals and broadcast messages. These 20 RBs will not be used by CORESET#0 or PDSCH. CORESET#0 can perform frequency domain multiplexing on the remaining 28 RBs and coexist with SSB. These 28 RBs can be used for control channel transmission (i.e., PDCCH) and data (i.e., PDSCH) transmission of CORESET#0. In this multiplexing mode, although SSB occupies 20 RBs and these RBs cannot be scheduled by PDSCH, CORESET#0 and PDSCH carrying configuration information can still use the remaining 28 RBs in the initial BWP for frequency domain multiplexing. This allocation method ensures that SSB resources are not interfered with by other signals while still providing sufficient resources for PDSCH for the transmission of configuration information.

[0079] In some implementations, when a terminal device receives configuration information, it may store the configuration information in its memory, so that the terminal device can use the configuration information at a time other than when the configuration information is sent.

[0080] In some implementations, the network device sends first indication information to the terminal device, and the first indication information is used to indicate the update of the configuration information. For example, the first cell is an NES cell, and the first indication information is an SI update indication. When the terminal device resides in the NES cell, the SI update indication can be obtained from the NES cell or from an anchor cell, and the SI update indication can indicate that there is an updated version of the configuration information.

[0081] In some implementations, before the terminal device sends the first request, if the terminal device receives the first indication information sent by the network device, the terminal device obtains the updated configuration information and stores the updated configuration information in its memory. For example, the first cell is an NES cell, the terminal device resides in the first cell, and before sending the first request, the terminal device receives the first indication information from the first cell, and can obtain the updated configuration information in the first cell, and store the updated configuration information in its memory. The configuration information is only associated with the first cell where it resides, and the terminal device can send the first request in the first cell based on the updated configuration information. For another example, the first cell is an NES cell, the terminal device resides in the first cell, and before sending the first request, the terminal device receives the first indication information from the anchor cell, and the first indication information indicates the update of the configuration information corresponding to the first cell. After receiving the first indication information, the terminal device can obtain the updated configuration information from the anchor cell, and the terminal device stores the updated configuration information in its memory. The configuration information is associated with the first cell and multiple other NES cells. The terminal device can send the first request based on the updated configuration information corresponding to the first cell where it resides, for obtaining SIB1 to re-reside in the first cell or initially access a new NES cell.

[0082] In some implementations, the updated configuration information may be obtained through SI and / or radio resource control (RRC) messages. For example, the first cell is a NES cell, and the first cell releases the updated configuration information through SI and / or RRC messages.

[0083] In the traditional scheme, SIB1 may have two transmission modes in the first cell: periodic SIB1 or no SIB1 transmission (SIB1-less), and the two modes can be identified by cell defining SSB (CD-SSB) or non-cell defining SSB (NCD-SSB). CD-SSB is an SSB associated with the remaining minimum system information (RMSI) (i.e. SIB1), and its PBCH payload parameter Kssb is set to a value of Kssb less than 24 in FR1 and a value of Kssb less than 12 in FR2; while for non-cell defining SSB (NCD-SSB), its Kssb is set to a value of Kssb greater than or equal to 24 in FR1 and a value of Kssb greater than or equal to 12 in FR2. If the first cell has CD-SSB (i.e., the value of Kssb in FR1 is less than 24 and the value of Kssb in FR2 is less than 12), the first cell has periodic SIB1. For CD-SSB, its MIB parameter "pdcch-ConfigSIB1" indicates the configuration of pdcch CoreSetZero and SearchSpaceZero for periodic SIB1 transmission. In addition to CD-SSB, the first cell with periodic SIB1 may have no or one or more NCD-SSBs.

[0084] In some implementations, if the first cell supports transmission of the target SIB1, the first cell may have three modes regarding SIB1 transmission: periodic SIB1, SIB1-less, or OD-SIB1.

[0085] Since traditional terminal devices can only recognize periodic SIB1 and SIB1-less, in order to avoid negative impact on traditional terminal devices (such as access to the first cell), in some implementations, if the first cell supports the transmission target SIB1, the SSB in the first cell is a non-cell defined SSB. In other words, for the first cell that supports the transmission target SIB1, its always-on SSB can be set to NCD-SSB, that is, the value of Kssb in FR1 is greater than or equal to 24, and the value of Kssb in FR2 is greater than or equal to 12. In other words, for the first cell that supports the transmission target SIB1, if the first cell has one or more SSBs, all SSBs should be NCD-SSBs.

[0086] In some implementations, if the terminal device does not support triggering SIB1 based on a request of the terminal device, and the first cell supports transmission of the target SIB1, the terminal device identifies OD-SIB1 as SIB1-less to avoid being unable to access the first cell. That is, if the first cell supports transmission of OD-SIB1, when a traditional terminal device receives NCD-SSB in the first cell, the traditional terminal device determines that SIB1 is not transmitted in the first cell.

[0087] In some implementations, if the terminal device does not support triggering SIB1 based on a request of the terminal device, the terminal device receives second information sent by the network device, and the second information is used to determine the search space of the cell-defined SSB transmitted in the first cell. Accordingly, the terminal device that does not support triggering SIB1 based on a request of the terminal device can search for the cell-defined SSB transmitted in the first cell based on the second information, and then receive SIB1 based on the search space of SIB1 carried in the cell-defined SSB to access the first cell.

[0088] In some implementations, the second information is carried in the MIB of the non-cell-defined SSB. For example, the second information is carried in the parameters pdcch-ConfigSIB1 and kssb of the MIB of the non-cell-defined SSB transmitted in the first cell, and the reserved values ​​of pdcch-ConfigSIB1 and kssb together indicate that the terminal device searches for auxiliary information of the CD-SSB.

[0089] However, for a terminal device that supports triggering SIB1 based on a request from the terminal device, the cell that transmits only NCD-SSB may be a cell that supports transmitting OD-SIB1 or a cell that supports transmitting SIB1-less. In order to further distinguish these two modes, in some implementations, if the terminal device supports triggering SIB1 based on a request from the terminal device, and the SSB of the first cell received by the terminal device is a non-cell-defined SSB, the terminal device determines whether the first cell supports transmitting the target SIB1 based on the first parameter and / or configuration information.

[0090] In some implementations, if the terminal device supports triggering SIB1 based on a request of the terminal device, and the SSB of the first cell received by the terminal device is a non-cell defined SSB, the terminal device determines whether the first cell supports the transmission target SIB1 based on the first parameter. For example, the first parameter is Kssb of the non-cell defined SSB, and the reserved value of Kssb (such as Kssb value of 30 in FR1 and Kssb value of 14 in FR2) indicates that the first cell supports the transmission target SIB1. In this case, the MIB parameter "pdcch-ConfigSIB1" of the non-cell defined SSB can also be reserved, and no auxiliary information will be provided for the traditional device to search for CD-SSB. For another example, the value of Kssb can also be within the range of NCD-SSB, that is, Kssb is set to a value of Kssb greater than or equal to 24 in FR1, and is set to a value of Kssb greater than or equal to 12 in FR2.

[0091] In some implementations, if the terminal device supports triggering SIB1 based on a request of the terminal device, and the SSB of the first cell received by the terminal device is a non-cell-defined SSB, the terminal device determines whether the first cell supports transmission of the target SIB1 based on the configuration information. For example, if all SSBs transmitted in the first cell are NCD-SSBs, and the first cell is associated with the configuration information, the first cell supports transmission of the target SIB1, that is, the first cell supports transmission of OD-SIB1; otherwise, the first cell does not support transmission of the target SIB1, but supports transmission of SIB1-less.

[0092] In some implementations, a terminal device that supports triggering SIB1 based on a request of the terminal device determines whether the first cell supports the transmission target SIB1 based on the configuration information. For example, if the configuration information is associated with the PCI of the first cell and / or the frequency information of the first cell, it can be determined that the first cell supports the transmission target SIB1; otherwise, the first cell does not support the transmission target SIB1.

[0093] In some implementations, a terminal device that supports triggering SIB1 based on a request from the terminal device determines whether the first cell supports the transmission target SIB1 based on the first parameter and configuration information. For example, the first parameter is Kssb, and the Kssb of the SSB transmitted by the first cell is set to a value greater than or equal to 24 in FR1, and is set to a value greater than or equal to 12 in FR2. The terminal device with NES capability determines that the SSB transmitted by the first cell is NCD-SSB based on the first parameter; the configuration information received by the terminal device is associated with the PCI of the first cell, and the terminal device can determine that the first cell supports the transmission target SIB1 based on the PCI of the first cell.

[0094] Embodiment 2: The first information is used to determine the transmission resources of the first request and / or the sequence information of the first request.

[0095] In some implementations, if the first information is used to determine a transmission resource of the first request and / or sequence information of the first request, the first information includes configuration information for configuring the first request.

[0096] It should be noted that the description of configuration information in Embodiment 1 is also applicable to Embodiment 2, which will not be described in detail. Of course, the description of configuration sub-information in Embodiment 2 is also applicable to Embodiment 1.

[0097] In some implementations, the configuration information is associated with one or more first cells, and the configuration information corresponding to the first cell is determined based on one or more of the following: transmission resources of the configuration information corresponding to the first cell; sequence information of the configuration information corresponding to the first cell.

[0098] In some implementations, the configuration information of the first cell is determined based on the sequence information of the configuration information corresponding to the first cell. For example, the configuration information is associated with multiple first cells, and the first cell is a NES cell. Different sequences can be assigned to the configuration information corresponding to different first cells, and the configuration information corresponding to different first cells can be determined based on the sequence information to avoid confusion and interference. For another example, a unique sequence (such as a Zadoff-Chu sequence, a Gold sequence, etc.) is assigned to each first cell as the sequence of the configuration information corresponding to each first cell. The configuration information is identified by a unique sequence, and each sequence has good autocorrelation and cross-correlation characteristics, which can effectively distinguish the configuration information corresponding to different first cells.

[0099] In some implementations, the configuration information corresponding to the first cell is determined based on the sequence information of the configuration information corresponding to the first cell. It can be understood that the sequence information of the configuration information corresponding to the first cell is associated with one or more of the following: the identity (ID) of the first cell; the load information of the first cell; the network parameters of the first cell. For example, the terminal device obtains the configuration information through the anchor cell, and the configuration information is associated with one or more first cells. The first cell is a NES cell. The anchor cell can generate a set of sequences. The commonly used sequence types can be Zadoff-Chu sequences, Gold sequences, etc. The sequence length and characteristics are selected according to system requirements to ensure sufficient sequence space and reliability. The anchor cell allocates the generated sequence to each first cell. The allocation can be based on the ID of the first cell, the load information of the first cell, or the network parameters of the first cell, so that the sequence information of the configuration information corresponding to each first cell is associated with its ID, load information, or network parameters. When the terminal device receives the configuration information, it can determine the sequence information of the configuration information corresponding to the first cell based on the ID, load information, or network parameters of the first cell, and then determine the configuration information corresponding to the first cell based on the sequence information of the configuration information corresponding to the first cell.

[0100] In some implementations, the ID of the first cell may be understood as an ID that can uniquely identify the first cell. For example, the ID of the first cell may be a PCI or other forms of identifiers.

[0101] In some implementations, the sequence information of the configuration information corresponding to the first cell is associated with the ID of the first cell, which can be understood as the sequence index of the configuration information corresponding to the first cell is associated with the ID of the first cell, that is, the sequence information of the configuration information includes the sequence index, and the sequence index of the configuration information corresponding to the first cell is associated with the ID of the first cell, or the ID of the first cell can be mapped to a specific sequence, and the index of the sequence serves as the sequence index of the configuration information corresponding to the first cell. It should be noted that the mapping rule of the ID mapping sequence of the first cell should ensure that different first cell IDs are mapped to different sequences, and the mapping process should be repeatable to ensure consistency.

[0102] In some implementations, the sequence index of the configuration information corresponding to the first cell is determined by the formula sequence_Index=cell ID mod N+1; wherein cell ID represents the ID of the first cell, mod represents the modulo operation, and N represents the total number of sequences. For example, the terminal device obtains configuration information through the anchor cell, the configuration information is associated with multiple first cells, the first cell is a NES cell, and the anchor cell generates a set of available sequences. Assuming that N sequences are generated, these sequences can be identified by sequence indexes (1 to N). The size N of the sequence pool should be large enough to cover all possible IDs of the first cells. The ID of the first cell is mapped to a sequence index in the sequence pool by the formula sequence_Index=cell ID mod N+1. For another example, for the first cell with ID 1003, if N=16, then by calculating 1003 mod 16=11, the first cell is assigned to the 12th sequence in the sequence pool, and each first cell obtains the corresponding sequence from the sequence pool according to its calculated sequence index to construct the configuration information as the sequence of the configuration information corresponding to each first cell. The ID of the first cell is mapped to a sequence index between 1 and N through a modulo operation. This method is simple and effective, and helps to evenly distribute the sequences.

[0103] In some implementations, the transmission resources of the first request corresponding to the first cell and / or the sequence information of the first request corresponding to the first cell are determined based on the sequence information of the configuration information corresponding to the first cell.

[0104] In some implementations, the sequence information of the first request corresponding to the first cell is determined based on the sequence information of the configuration information corresponding to the first cell, which can be understood as the sequence information of the first request corresponding to the first cell being the sequence information of the configuration information corresponding to the first cell. For example, the first cell is a NES cell, and terminal devices residing in different first cells receive configuration information from the anchor cell, can obtain the sequence information of the configuration information corresponding to the first cell, and carry the sequence information in the first request, so that the first cell can determine the terminal device sending the first request based on the sequence information of the received first request, and further distinguish whether the first request belongs to itself.

[0105] In some implementations, the transmission resources of the first request corresponding to the first cell include physical resource blocks (PRBs), that is, the resources of transmitting the first request corresponding to the first cell include PRBs.

[0106] In some implementations, the PRB index of the first request corresponding to the first cell is determined based on the sequence index of the configuration information corresponding to the first cell and / or the ID of the terminal device. That is, based on the sequence index of the configuration information corresponding to the first cell and / or the ID of the terminal device, the PRB resources for transmitting the first request within the first cell can be determined.

[0107] In some implementations, the initial PRB index of the first request corresponding to the first cell is calculated by the formula PRB_Index INIT =(sequence_Index*K)mod M; wherein, sequence_Index represents the sequence index of the configuration information corresponding to the first cell, K represents the mapping factor, mod represents the modulo operation, and M represents the total length of the PRB for transmitting the first request set by the first cell.

[0108] It should be noted that the total PRB length M for transmitting the first request set in each first cell is the same.

[0109] In some implementations, the total PRB length M for transmitting the first request is determined based on the maximum PRB length of the first request set for the first cell and / or the number of terminal devices supported.

[0110] In some implementations, the PRB index of the first request corresponding to the first cell transmitted by the i-th terminal device is determined based on the initial PRB index of the first request corresponding to the first cell and the ID of the i-th terminal device.

[0111] In order to ensure a one-to-one correspondence between the ID of the terminal device and the PRB index in the PRB pool of the first request transmitted in the first cell, in some implementations, the PRB index of the first request corresponding to the first cell transmitted by the i-th terminal device is calculated by the formula PRB_Index(i)=UE_ID(i)mod M+PRB_Index INIT Determine; where UE_ID(i) represents the ID of the i-th terminal device, mod represents the modulus operation, and PRB_Index INIT Represents the initial PRB index of the first request corresponding to the first cell. It should be noted that UE_ID is a positive integer, and different UE_IDs should generate different PRB_Index after being mapped by the above formula to avoid conflicts. And the PRB_Index calculated each time for the same UE_ID is consistent, and the formula can adapt to different numbers of terminal devices and available PRB numbers. At the same time, this method can ensure that when M is less than or equal to the number of PRB pools, all UE_IDs are mapped to different PRB_Index.

[0112] In some implementations, the PRB index of the first request corresponding to the first cell transmitted by the i-th terminal device is calculated by the formula PRB_Index(i)=[a*UE_ID(i)+b]mod M+PRB_Index INIT Determine; where a and b represent preconfigured constants, UE_ID(i) represents the ID of the i-th terminal device, mod represents the modulus operation, PRB_Index INIT Indicates the initial PRB index of the first request corresponding to the first cell. The preconfigured constants a and b can increase the randomness and dispersion of the mapping, help increase the uniformity of the mapping, and prevent excessive congestion of certain PRB_Index.

[0113] In some implementations, a may be a prime number greater than M, which helps avoid periodic overlap.

[0114] In some implementations, the PRB index of the first request corresponding to the first cell transmitted by the i-th terminal device is calculated by the formula PRB_Index(i)=[Hash(UE_ID(i))]mod M+PRB_Index INIT Determine; wherein Hash(·) represents a hash function, UE_ID(i) represents the ID of the i-th terminal device, mod represents a modulus operation, PRB_Index ININT Indicates the initial PRB index of the first request corresponding to the first cell. The hash function can ensure that the mapping is well distributed. Even if the UE_IDs are very close, the mapped PRB_Index may be completely different, which helps to cope with the situation where the UE_IDs are relatively dense and adapt to more complex network environments.

[0115] The above describes, through Example 1 and Example 2, the related scheme of using the first information to determine whether the first cell supports the target SIB1, and the related scheme of using the first information to determine the transmission resource of the first request and / or the sequence information of the first request. In some scenarios, Example 1 and Example 2 can be used alone. In other scenarios, Example 1 and Example 2 can be used in combination.

[0116] For ease of understanding, the following Figure 4 , an example is given to introduce a solution combining Example 1 and Example 2.

[0117] Assume that the first information is used to determine whether the first cell supports the target SIB1, the transmission resources of the first request, and the sequence information of the first request. The first information includes configuration information, and the configuration information associates the PCIs of the two first cells. Figure 4The two first cells are respectively the first NES cell and the second NES cell, the terminal device residing in the first NES cell is the first terminal device, and the terminal device residing in the second NES cell is the second terminal device.

[0118] Continue to see Figure 4 , the anchor cell sends configuration information to the terminal devices residing in the first NES cell and the second NES cell. After receiving the configuration information, the first terminal device residing in the first NES cell and the second terminal device residing in the second NES cell determine that the first NES cell and the second NES cell support the transmission target SIB1 based on the PCI of the cell obtained from the SSB of each cell. At the same time, the first terminal device and the second terminal device determine the sequence information of the configuration information corresponding to them respectively based on the ID of the first NES cell and the ID of the second NES cell, and determine the transmission resources and sequence information of the first request corresponding to the first NES cell and the first request corresponding to the second NES cell based on the sequence information of the configuration information corresponding to them respectively. Finally, the first terminal device and the second terminal device send the first request to the first NES cell and the second NES cell respectively based on the transmission resources and sequence information of the first request respectively determined. The first NES cell and the second NES cell receive the first request and determine whether the first request is the first request corresponding to them based on the sequence information of the first request. If the first NES cell and the second NES cell determine that the first request is the first request corresponding thereto, the first NES cell and the second NES cell send the target SIB1 to the first terminal device and the second terminal device respectively.

It should be understood that the description of the method embodiment corresponds to the description of the device embodiment, so the parts not described in detail can refer to the previous method embodiment.
