[0170] FIG1a is a schematic diagram showing the architecture of a communication system according to an embodiment of the present disclosure.
[0171] As shown in FIG. 1 a , a communication system 100 includes a terminal 101 and a network device 102 .
[0172] In some embodiments, the network device includes an access network device and a core network device.

[0175] In some embodiments, the technical solution of the present disclosure can be applied to the Open RAN architecture. In this case, the interfaces between or within the access network devices involved in the embodiments of the present disclosure can be transformed into internal interfaces of the Open RAN, and the processes and information interactions between these internal interfaces can be implemented through software or programs.
[0176] In some embodiments, the access network device can be composed of a centralized unit (CU) and a distributed unit (DU), where the CU can also be called a control unit. The CU-DU structure can be used to split the protocol layer of the access network device, with the functions of some protocol layers centrally controlled by the CU, and the functions of the remaining part or all of the protocol layers distributed in the DU, which is centrally controlled by the CU, but is not limited to this.
[0177] In some embodiments, a core network device may be a device including one or more network elements, or may be multiple devices or device groups, each including all or part of the one or more network elements. The network element may be virtual or physical. The core network may include, for example, at least one of an Evolved Packet Core (EPC), a 5G Core Network (5GCN), and a Next Generation Core (NGC).

Ordinary technicians in this field can know that with the evolution of the system architecture and the emergence of new business scenarios, the technical solution provided by the embodiment of the present disclosure is also applicable to similar technical problems.
[0179] The following embodiments of the present disclosure may be applied to the communication system 100 shown in FIG1a, or a portion thereof, but are not limited thereto. The entities shown in FIG1a are illustrative only. The communication system may include all or a portion of the entities shown in FIG1a, or may include other entities other than those shown in FIG1a. The number and form of the entities may be arbitrary. The connection relationship between the entities is illustrative only.

[0180] The embodiments of the present disclosure can be applied to Long Term Evolution (LTE), LTE-Advanced (LTE-A), LTE-Beyond (LTE-B), SUPER 3G, IMT-Advanced, 4th generation mobile communication system (4G), 5th generation mobile communication system (5G), 5G new radio (NR), future radio access (FRA), new radio access technology (RAT), new radio (NR), new radio access (NX), future generation radio access (FX), Global System for Mobile Communications (GSM (registered trademark)), CDMA2000, Ultra Mobile Broadband (UMB), IEEE 802.11 (Wi-Fi (registered trademark)), IEEE 802.16 (WiMAX (registered trademark)), IEEE 802.20, Ultra-WideBand (UWB), Bluetooth (registered trademark), Public Land Mobile Network (PLMN) networks, Device-to-Device (D2D) systems, Machine-to-Machine (M2M) systems, Internet of Things (IoT) systems, Vehicle-to-Everything (V2X), systems utilizing other communication methods, and next-generation systems based on and extending these methods. Furthermore, multiple systems may be combined (for example, a combination of LTE or LTE-A with 5G).
[0181] In some cases, IoT devices in IoT networks are often powered by traditional batteries with limited lifespans, negatively impacting user experience. The astronomical growth of IoT networks, coupled with the proliferation of IoT devices, has pushed maintenance expenses, including labor and battery costs, to a whole new level. Billions of traditional batteries are discarded each year, with only a small fraction effectively recycled, negatively impacting the Earth's ecosystem. Maintaining IoT network operations and replacing batteries can be extremely challenging in extreme environmental conditions. Battery-free IoT communications have been proposed to improve network performance and sustainability, expanding their application scenarios. Furthermore, battery-free communications are more environmentally friendly and safer for children and the elderly. Eliminating traditional batteries significantly reduces device size and cost, paving the way for a variety of new applications.
[0182] In some embodiments, in the era of the fifth generation mobile communication technology 5G, various low power wide area (LPWA) technologies have been developed, such as machine type communication (MTC), narrowband Internet of Things (NB-IoT), reduced capability (RedCap), etc., to meet the growing needs of vertical fields. These LPWA technologies achieve low cost, low power consumption and large-scale connectivity, which can meet the requirements of many applications. However, there are still many use cases and applications that cannot be solved in the following situations. First, devices driven by traditional batteries are not applicable, such as in extreme environmental conditions (such as high voltage, extremely high / low temperature, humid environment). Second, maintenance-free equipment is required (for example, there is no need to replace traditional batteries of the device). Finally, ultra-low complexity, very small device size / form factor (such as mm thickness), longer life cycle, etc. are required.
[0183] In some embodiments, 5G is introduced to meet people's pursuit of speed, latency, high-speed mobility, energy efficiency, and the diversity and complexity of services in future life.
[0184] In some embodiments, the main application scenarios of 5G include: enhanced mobile ultra-wideband (eMBB), ultra-reliable low-latency communication (URLLC), and massive machine type communication (mMTC).
[0185] In some embodiments, eMBB still aims to provide users with multimedia content, services, and data, and demand for this is growing rapidly. Furthermore, since eMBB may be deployed in different scenarios, such as indoors, in urban areas, and in rural areas, its capabilities and requirements vary significantly. Therefore, it is not possible to generalize and requires detailed analysis based on specific deployment scenarios.
[0186] In some embodiments, typical applications of URLLC include industrial automation, power automation, remote medical operations (surgery), and traffic safety assurance.
[0187] In some embodiments, typical features of mMTC include: high connection density, small data volume, latency-insensitive services, low module cost and long service life.
[0188] After the introduction of 5G technology, the energy consumption of 5G base stations is four times that of LTE base stations, so network energy saving is an important means for operators to reduce the cost of operating 5G systems.
[0189] In some embodiments, in order to save energy for terminals in a radio resource control (RRC) connected state, a power saving signal (WUS) is introduced. An offset in front of the on duration of the discontinuous reception (C-DRX) in the UE connected state defines a duration for sending the WUS signal. During this WUS duration, the WUS signal, i.e., downlink control information (DCI) 2-6, is sent and scrambled by the power saving signal-radio network temporary identifier (PS-RNTI) to indicate whether the terminal wakes up to monitor the physical downlink control channel (PDCCH) during the next UE C-DRX onduration.
[0190] In some embodiments, a paging WUS is introduced to save energy for terminals in RRC idle or inactive states. This WUS, also known as a Paging Early Indication (PEI), is sent sometime before a paging occasion (PO) to indicate whether the terminal is monitoring paging scheduling information at that PO. The PEI is DCI 2-7, scrambled using the PEI-RNTI.
[0191] In some embodiments, in order to reduce network energy consumption, a network energy saving project is launched. The four supported network energy saving (NES) functions include:
[0192] SSB-less Scell;
[0193] cell DTX / DRX;
[0194] Antenna port adaptation;
[0195] PDSCH transmission power adaptation.
[0196] In some embodiments, for a network energy-saving method for cell discontinuous transmission (DTX) or discontinuous transmission (DRX), the network side configures the cell's DTX or DRX operation pattern through dedicated radio resource control (RRC) signaling, i.e., configures a period, offset, and / or duration. During the onduration, the cell is in an active state and can receive and transmit data. The rest of the time is considered inactive time, and the network side generally does not receive or transmit data, except in special circumstances. For example, transmission processes such as synchronization signal blocks (SSB and PBCH blocks), master information block (MIB) messages, system information block (SIB) messages, paging messages, and random access channel (RACH) messages are not affected and proceed normally.
[0197] In some embodiments, DCI 2-9 is a group common DCI, which is used to notify the UE about the activation and deactivation of cell DTX and DRX of the cell. In NES, it also includes cell switch off. Due to cell DTX / DRX activation or cell switch off, the terminal that supports NES cannot work or cannot meet the high performance requirements of the terminal, so the terminal needs to switch to other cells at this time. For this reason, the conditional handover CHO for NES, namely NES CHO (Conditional HandOver), is introduced in NES. At the same time, the handover is triggered based on the 1-bit instruction of DCI, that is, when the NES CHO handover condition is met and the DCI handover instruction from the network side is received, the handover is performed. In the related art, DCI is DCI format 2-9, that is, the DCI for reusing cell DTX / DRX activation and deactivation is reused.
[0198] In some embodiments, the content of the system broadcast includes a Master Information Block (MIB), Remaining Minimum System Information (RMSI) (ie, System Information Block 1 SIB1) and Other System Information (OSI).
[0199] In some embodiments, SIB1 is configured with configuration parameters related to cell selection, cell access, OSI scheduling, cell common configuration, access control, and cell capability. The control resource set (CORESET) of SIB1 is configured in the MIB. There are three types of multiplexing relationships between the RMSI CORESET and the synchronization information block (SS / PBCH block) resources (see Figure 1b: pattern 1: TDM; pattern 2: TDM+FDM; pattern 3: FDM). The UE obtains the resource location of the PDCCH based on the RMSI CORESET information in the physical broadcast channel (PBCH), thereby further receiving the RMSI.
[0200] In some embodiments, in the new air interface, in order to save energy on the network side, reduce the amount of system information broadcast by the base station by default and save radio resources, a request-based system broadcast transmission is proposed.
[0201] In some embodiments, except for MIB and SIB1, other SIBs can be requested on demand, that is, the base station will broadcast them only after receiving a system information (SI) request from the UE.
[0202] In some embodiments, SIB1 carries an indication of whether each SI is being broadcast, and the UE can learn which SIBs require SI requests by reading SIB1.
[0203] In some embodiments, the SI request method includes MSG1-based SI request and MSG3-based SI request.
[0204] In some embodiments, the MSG1-based SI request is based on reserved preamble and / or random access channel (RACH) resources.
[0205] In some embodiments, MSG3-based SI does not require the reservation of RACH preamble, which is defined as RRCSystemInfoRequest message (MSG3).
[0206] In some embodiments, the UE learns whether to adopt MSG1-based or MSG3-based SI request by reading system information.
[0207] In some embodiments, if the base station provides the configuration information of the SI request, ie, si-Request-Config, in the system information (SIB1), the MSG1-based SI request is used; otherwise, the MSG3-based SI request is used.
[0208] In some embodiments, the UE receives SI in the current modification period after receiving the SI request confirmation. The UE receives the SI to know that the modification period ends or that the SI is received. If RACH fails during the SI request process, the subsequent behavior of the UE depends on the UE implementation.
[0209] In some embodiments, SI requests from UEs in RRC connected state are not supported.
[0210] For example, referring to FIG1c , it includes:
[0211] Step S1101: The network device (Network) sends the MIB;
[0212] Step S1102: The network device sends SIB1;
[0213] Step S1103, the terminal (UE) sends a system information request (SystemInformationRequest);
[0214] In step S1104, the network device sends system information messages.
[0215] In some embodiments, in the new air interface system, for cells that support the configured and activated cell DTX or DRX function, legacy UEs are barred, but for R19 terminals that support cell DTX or DRX function, they are not barred. For cells that support SIB1 request type, the processing mechanism for legacy UEs and R19 UEs needs to be considered.
[0216] FIG2a is an interactive diagram of an information indication method according to an embodiment of the present disclosure. As shown in FIG2a, the embodiment of the present disclosure relates to an information indication method, which is used in a communication system 100 and includes:
[0217] Step S2101: The network device sends first information to the terminal.
[0218] In some embodiments, the terminal receives first information sent by the network device.
[0219] In some embodiments, the terminal receives first information sent by the access network device.
[0220] In some embodiments, the terminal includes a first type terminal and / or a second type terminal, the first type terminal is a terminal that does not support requesting SIB1, and the second type terminal is a terminal that supports requesting SIB1.
[0221] In some embodiments, the second type of terminal may be a network energy saving capable terminal (NES capable UE). The NES capable UE may be a terminal supporting an on-demand SIB1 function, that is, the second type of terminal supports requesting SIB1 from a network device through a request message.
[0222] In some embodiments, the first information is used to indicate whether the first cell is in a prohibited state.
[0223] In some embodiments, the prohibited state is a state in which the terminal is prohibited from camping on the first cell.
[0224] In some embodiments, the first cell is a cell capable of sending system information block 1 SIB1 upon request (on-demand SIB1 required cell).
[0225] In some embodiments, the network device is a first network device corresponding to the first cell.
[0226] In some embodiments, the terminal receives a master information block MIB sent by the network device.
[0227] In some embodiments, the MIB includes the first information.
[0228] In some embodiments, the first information field of the MIB is used to indicate that the first cell is in a prohibited state.
[0229] In some embodiments, the prohibited state is a state in which the first type terminal is prohibited from camping on the first cell.
[0230] Illustratively, for an on-demand SIB1 required cell, the legacy UE can detect the cell, but the cell is in a barred state (ie, barred) for the legacy UE. For example, cellBarred (corresponding to the first information field) in the MIB is set to barred.
[0231] In some embodiments, the MIB includes the first information field and the second information field.
[0232] In some embodiments, the second information field is used to indicate whether the second type terminal is prohibited from camping in the first cell.
[0233] Exemplarily, if the cellBarred (first information field) in the MIB is set to barred, the cellBarred is used to prohibit legacy UEs or UEs that do not support requesting SIB1 from residing in the on-demand SIB1 required cell (first cell), then the spare bit (second information field) in the MIB is used to indicate whether the cell is barred for terminals that support requesting SIB1 (second type terminals).
[0234] In some embodiments, the second information field carries a first value, and the second information field is used to indicate that the second type terminal is allowed to reside in the first cell.
[0235] In some embodiments, the second information field carries a second value, and the second information field is used to indicate that the second type of terminal is prohibited from camping on the first cell.
[0236] For example, a value of "1" indicates that the cell is not in a barred state (not barred) for the second type of terminal.
[0237] In some embodiments, the MIB includes the first information field and the third information field.
[0238] In some embodiments, the third information field indicates synchronization signal block SSB subcarrier offset information; a reference value determined based on the synchronization signal block SSB subcarrier offset information indicates whether the second type terminal is prohibited from residing in the first cell.
[0239] In some embodiments, the reference value is within a first range, and the third information field is used to indicate that the second type terminal is allowed to reside in the first cell.
[0240] In some embodiments, the reference value is not within the first range, and the third information field is used to indicate that the second type terminal is prohibited from camping in the first cell.
[0241] For example, if the cellBarred (first information field) in the MIB is set to barred, the cellBarred is used to prohibit legacy UEs (first type terminals) or UEs that do not support requesting SIB1 from residing in the on-demand SIB1 required cell (first cell). If the value in the MIB is the K corresponding to ssb-SubcarrierOffset (third information field), SSB The value of (reference value) is 0-23 (corresponding to frequency range 1FR1) and 0-11 (corresponding to frequency range 2FR2), indicating that the cell is not barred for UE (second type terminal) supporting SIB1 request.
[0242] In some embodiments, ssb-SubcarrierOffset is 4 bits, and for FR1 there is an additional 1 bit in the physical layer signaling of the MIB, for a total of 5 bits.
[0243] Step S2102: The terminal sends second information to the network device.
[0244] In some embodiments, the network device receives second information sent by the terminal.
[0245] In some embodiments, the terminal sends second information to the network device, where the second information is used to request the SIB1.
[0246] In some embodiments, the terminal receives the SIB1 sent by the network device, where the SIB1 includes third information, and the third information is used to indicate whether the second type terminal is prohibited from camping on the first cell.
[0247] In some embodiments, the third information indicates a first value, and the third information is used to indicate that the second type terminal is prohibited from camping on the first cell.
[0248] In some embodiments, the third information indicates a second value, and the third information is used to indicate that the second type terminal is allowed to camp on the first cell.
[0249] For example, for an on-demand SIB1 required cell, the cellBarred setting in the MIB is barred. This cellBarred setting is used to prohibit legacy UEs or UEs that do not support requesting SIB1 from camping on the on-demand SIB1 required cell. For UEs that support requesting SIB1, SIB1 can be requested by sending second information to a network device. The network device sends SIB1 to the terminal. SIB1 includes third information, which is used to indicate whether the UE supporting the SIB1 request function is barred. If it indicates not barred, the UE is not barred; otherwise, it is barred.
[0250] In some embodiments, the terminal obtains fourth information; wherein the fourth information is used to indicate that the first cell is a cell capable of sending system information block 1 SIB1 based on a request and / or resource configuration information for requesting the SIB1.
[0251] In some embodiments, the UE stores fourth information obtained from other cells or the current cell, where the fourth information is used to indicate that the cell is an on-demand SIB1 required cell and / or resource configuration information for requesting SIB1.
[0252] In some embodiments, the fourth information is determined based on an information field of the MIB.
[0253] In some embodiments, the fourth information is determined based on fifth information.
[0254] In some embodiments, the fifth information is information obtained from the first cell or the third cell.
[0255] In some embodiments, the fourth information is determined based on sixth information.
[0256] In some embodiments, the sixth information indicates a physical cell identity PCI.
[0257] In some embodiments, the fourth information is determined based on seventh information.
[0258] In some embodiments, the seventh information is used to indicate a frequency list.
[0259] In some embodiments, the fourth information is determined based on a reference quantity.
[0260] In some embodiments, the reference amount is determined based on the synchronization signal block SSB subcarrier offset information of the MIB.
[0261] In some embodiments, the MIB includes a first information field and a third information field.
[0262] In some embodiments, the third information field indicates synchronization signal block SSB subcarrier offset information.
[0263] In some embodiments, the size of the reference value determined based on the synchronization signal block SSB subcarrier offset information indicates whether the first type terminal and the second type terminal are prohibited from residing in the first cell.
[0264] In some embodiments, the reference value is within a second range, and the third information field is used to indicate that the first type terminal and the second type terminal are allowed to reside in the first cell.
[0265] In some embodiments, the reference value is not within the second range, and the third information field is used to indicate that the first type terminal and the second type terminal are prohibited from camping in the first cell.
[0266] For example, for an on-demand SIB1 required cell, the cellBarred setting in the MIB is barred, which is used to prohibit legacy UEs or UEs that do not support requesting SIB1 from residing in the on-demand SIB1 required cell. Moreover, if the value of KSSB corresponding to the value of ssb-SubcarrierOffset in the MIB is greater than 23 (FR1) and greater than 11 (FR2), it means that the cell is barred. There is no difference between legacy UEs and UEs that support requesting SIB1, and both are barred. Or if the value of KSSB corresponding to ssb-SubcarrierOffset in the MIB is greater than 23 (FR1) and greater than 11 (FR2), it means that the cell is barred. SSB The value of 30 (FR1) and 14 (FR2) indicates that the cell is barred. There is no difference between legacy UEs and R19 UEs that support SIB1 request, both are barred.
[0267] In some embodiments, the network device is a second network device corresponding to a second cell outside the first cell.
[0268] In some embodiments, receiving a system information block 3 SIB3 or a system information block 4 SIB4 sent by the network device;
[0269] In some embodiments, the SIB3 includes the first information.
[0270] In some embodiments, the SIB4 includes the first information.
[0271] In some embodiments, the first information is used to indicate that the first cell is in a barred state.
[0272] In some embodiments, the prohibited state is a state in which the first type terminal is prohibited from camping on the first cell.
[0273] In some embodiments, the first information indicates that the first cell is deployed in units of frequency layers and a first frequency list for the first type of terminal to perform cell selection or reselection is not configured for the frequency layer.
[0274] In some embodiments, the first information indicates that the first cell is deployed in units of frequency layers and a second frequency list for the second type of terminal to perform cell selection or reselection is configured for the frequency layer.
[0275] In some embodiments, the first information indicates that the first cell is deployed in a cell unit and instructs the first type terminal to perform cell selection or reselection excluding the first cell.
[0276] In some embodiments, the first information indicates that the first cell is deployed in a cell unit and indicates that the second terminal performs cell selection or reselection of the first cell.
[0277] In some embodiments, the first information indicates a cell list, the cell list includes cells for the second terminal to select or reselect, and the cells include the first cell.
[0278] In some embodiments, if the on-demand SIB1 required cell is deployed per frequency, the frequency layer will not be configured in the cell selection and reselection frequency list in the SIB, for example, in SIB3 / 4, but for R19 NES terminals (second type terminals), an additional frequency list is configured, which is used for cell selection / reselection. This frequency list is only used for terminals that support SIB1 requests (second type terminals).
[0279] In some embodiments, if the on-demand SIB1 required cell is deployed per cell, the cell will be stored in the SIB, such as SIB3 / 4, for example, in the IntraFreqExcludedCellList in SIB3 and the interFreqExcludedCellList in SIB4 (stored in the InterFreqCarrierFreqInfo in SIB4, which is a per-frequency configuration exclusion list). However, for R19 NES terminals (second-type terminals), an additional cell list is configured per frequency. The cell list is used for cell selection / reselection. This cell list is only used for terminals that support SIB1 requests, indicating that NES terminals can reselect to cells in this list.
[0280] Step S2103: The terminal selects a cell to reside in based on the first information.
[0281] In some embodiments, if the first cell is not in a barred state, the terminal may select the first cell to camp on.
[0282] In some embodiments, if the first cell is in a barred state, the terminal may select a second cell to camp on.
[0283] In some embodiments, if the first cell is not in a barring state for the second type terminal and is in a barring state for the first type terminal, the second type terminal may select the first cell to camp on and the first type terminal may select the second cell to camp on.
[0284] Step S2104: The terminal sends a first signal to the network device.
[0285] In some embodiments, the network device receives a first signal sent by the terminal.
[0286] In some embodiments, the terminal sends a first signal to the network device on a first resource.
[0287] In some embodiments, the first signal is used to request the SIB1.
[0288] In some embodiments, there is a predetermined positional relationship between the frequency domain position and / or time domain position of the first resource relative to the resource position of the synchronization signal block.
[0289] It should be noted that in a time division duplexing (TDD) system, the system defines resources similar to scheduling requests (SR) as first resources, and the frequency domain position and / or time domain position of the first resource has a predefined relationship with the position of the synchronization signal fast SSB.
[0290] In some embodiments, the system defines a fixed slot in an odd-numbered System Frame Number (SFN) or even-numbered SFN, or in each SFN, based on a reference SCS. For example, the location of the last slot determines the location of a resource similar to an SR. The reference SCS is also defined in the system.
[0291] In some embodiments, the reference SCS is offset by x slots relative to the SSB. The reference SCS and the value of x are also defined in the system.
[0292] In some embodiments, the terminal determines that the cell is a cell that supports requesting SIB1, then the UE sends a first signal on a predefined resource. The first signal can be a predefined sequence or any message. The network side detects the energy of the resource and determines whether there is a UE requesting SIB1. If so, it triggers the sending of SIB1.
[0293] In some embodiments, the term "information" can be interchangeable with terms such as "message", "signal", "signaling", "report", "configuration", "indication", "instruction", "command", "channel", "parameter", "field", and "data".
[0294] In some embodiments, the term "send" can be interchanged with terms such as "transmit", "report", and "transmit".

[0386] Figure 5a is an interactive diagram of an information indication method according to an embodiment of the present disclosure. As shown in Figure 5a, the present disclosure embodiment relates to an information indication method, which is used in a communication system 100 and includes one of the following steps:
[0387] Step S5101: The network device sends first information to the terminal.
[0388] In some embodiments, the first information is used to indicate: whether the first cell is in a prohibited state; the first cell is a cell capable of sending system information block 1 SIB1 based on a request; the prohibited state is a state in which the terminal is prohibited from residing in the first cell.
[0389] The optional implementation of step S5101 can refer to the optional implementation of step S2101 in Figure 2a and other related parts of the embodiment involved in Figure 2a, which will not be repeated here.
[0390] In some embodiments, the above method may include the methods of the above-mentioned communication system side, terminal side, network device side, etc. embodiments, which will not be repeated here.
[0391] In order to better understand the embodiments of the present disclosure, the present disclosure is further described below through some exemplary embodiments:
[0392] Example 1
[0393] Solution 1: For legacy UEs (corresponding to the first type of terminal) and R19 NES Capable UEs (corresponding to the second type of terminal), handle the on-demand SIB1 required cell residency problem:
[0394] In some embodiments, for legacy UEs:
[0395] In some embodiments, for on-demand SIB1 required cells, legacy UEs can detect them, but they are barred for legacy UEs, for example, cellBarred in the MIB is set to barred.
[0396] In some embodiments, legacy UEs cannot detect on-demand SIB1 required cells. For example, if the on-demand SIB1 required cell is deployed per frequency, the frequency layer will not be configured in the cell selection reselection frequency list in the SIB, such as SIB3 / 4. If the on-demand SIB1 required cell is deployed per cell, the cell will be present in the SIB, such as SIB3 / 4, such as the IntraFreqExcludedCellList in SIB3 and the interFreqExcludedCellList in SIB4 (which is the InterFreqCarrierFreqInfo in SIB4 and is a per frequency configuration exclusion list).
[0397] In some embodiments, for R19 NES capable UE, which refers to a UE that supports the on-demand SIB1 function:
[0398] In some embodiments, if the cellBarred in the MIB is set to barred in order to prohibit legacy UEs or UEs that do not support requesting SIB1 from residing in the on-demand SIB1 required cell, the spare bit in the MIB is used to indicate whether the cell is barred for terminals that support requesting SIB1 in R19, for example, a value of "1" indicates not barred.
[0399] In some embodiments, if the cellBarred setting in the MIB is set to barred, the purpose is to prohibit legacy UEs or UEs that do not support SIB1 requests from camping on the on-demand SIB1 required cell. If the KSSB value corresponding to the ssb-SubcarrierOffset value in the MIB is 0-23 (FR1) and 0-11 (FR2), it means that the cell is not barred for UEs that support SIB1 requests in R19. (ssb-SubcarrierOffset is 4 bits, and for FR1 there is an additional 1 bit in the physical layer signaling of the MIB, for a total of 5 bits)
[0400] In some embodiments, for cells requiring on-demand SIB1, the cellBarred field in the MIB is set to barred. This is to prevent legacy UEs or UEs that do not support requesting SIB1 from camping on cells requiring on-demand SIB1. For R19 UEs that support requesting SIB1, SIB1 is requested, and SIB1 indicates whether the UE supporting R19 requesting SIB1 is barred. If it indicates not barred, the R19 UE is not barred; otherwise, it is barred.
[0401] In some embodiments, the UE obtains information from other cells or the current cell, indicating that the cell is an on-demand SIB1 required cell, and / or requests SIB1 configuration information.
[0402] In some embodiments, for on-demand SIB1 required cells, cellBarred in the MIB is set to barred in order to prohibit legacy UEs or UEs that do not support SIB1 from residing in on-demand SIB1 required cells. Furthermore, if the KSSB value corresponding to the ssb-SubcarrierOffset value in the MIB is >23 (FR1) and >11 (FR2), it indicates that the cell is barred. For legacy UEs and R19 UEs that support SIB1, both are barred. Alternatively, if the KSSB value corresponding to the ssb-SubcarrierOffset value in the MIB is 30 (FR1) and 14 (FR2), it indicates that the cell is barred. For legacy UEs and R19 UEs that support SIB1, both are barred.
[0403] In some embodiments, if the on-demand SIB1 required cell is deployed per frequency, the frequency layer will not be configured in the cell selection and reselection frequency list in the SIB, for example, SIB3 / 4, but for R19 NES terminals, an additional frequency list is configured, which is used for cell selection / reselection. The NES list is only used for terminals that support SIB1 requests.
[0404] In some embodiments, if the on-demand SIB1 required cell is deployed per cell, the cell will be stored in the SIB, for example, SIB3 / 4, such as the IntraFreqExcludedCellList in SIB3 and the interFreqExcludedCellList in SIB4 (stored in the InterFreqCarrierFreqInfo in SIB4, which is a per-frequency configuration exclusion list). However, for R19 NES terminals, an additional cell list is configured per frequency. The cell list is used for cell selection / reselection. This cell list is only used for terminals that support SIB1 requests, indicating that NES terminals can reselect to cells in this list.
[0405] Example 2:
[0406] Solution 2: UE requests SIB1 based on uplink signal
[0407] In some embodiments, in a TDD system, the system defines resources similar to SR, and the frequency domain position and / or time domain position of the resources has a predefined relationship with the position of the SSB.
[0408] In some embodiments, the system defines an SR-like resource location (corresponding to the first resource) in an odd-numbered SFN or an even-numbered SFN, or in each SFN, according to a fixed slot of a reference SCS, such as the last slot. The reference SCS is also defined in the system.
[0409] In some embodiments, the reference SCS is offset by x slots relative to the SSB. The reference SCS and the value of x are also defined in the system.
[0410] In some embodiments, the terminal determines that the cell is a cell that supports requesting SIB1, and the UE sends a signal (corresponding to a first signal) on a predefined resource (corresponding to a first resource). The signal can be a predefined sequence or any message. The network side detects the energy of the resource and determines whether there is a UE requesting SIB1. If so, it triggers the sending of SIB1.
[0411] In some embodiments, the UE may obtain that the current cell is an on-demand SIB1 required cell in at least one of the following ways:
[0412] A bit in the MIB is used to indicate that the cell is an on-demand SIB1 required cell, or to indicate that the cell is not barred for R19 NES capable UE, such as the spare bit;
[0413] The UE obtains information from other cells or the current cell, indicating that the cell is an on-demand SIB1 required cell;
[0414] PCI indication, the system reserves the PCI rang or PCI list of cells that support SIB1 request;
[0415] Frequency list indication, the system reserves the frequency list of cells that support SIB1 requests;
[0416] The KSSB value corresponding to ssb-SubcarrierOffset in the MIB ranges from 0 to 23 (FR1) and 0 to 11 (FR2), and SIB1 cannot be obtained, or cellbarred is set to barred. And / or the cell RSRP measurement value is greater than the system-defined threshold.
[0417] In the embodiments of the present disclosure, some or all of the steps and their optional implementations may be arbitrarily combined with some or all of the steps in other embodiments, or may be arbitrarily combined with the optional implementations of other embodiments.
