[0153] 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. The entities may be connected or disconnected, and the connection may be in any manner, including direct or indirect, wired or wireless.
[0154] 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).
[0155] 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.
[0156] 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).
[0157] 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.
[0158] In some embodiments, typical applications of URLLC include industrial automation, power automation, remote medical operations (surgery), and traffic safety assurance.
[0159] In some embodiments, typical features of mMTC include: high connection density, small data volume, latency-insensitive services, low module cost and long service life.
[0160] 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.
[0161] 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.
[0162] 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.
[0163] 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:
[0164] SSB-less Scell;
[0165] cell DTX / DRX;
[0166] Antenna port adaptation;
[0167] PDSCH transmission power adaptation.
[0168] 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.
[0169] 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.
[0170] 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).
[0171] 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.
[0172] 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.
[0173] 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.
[0174] 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.
[0175] In some embodiments, the SI request method includes MSG1-based SI request and MSG3-based SI request.
[0176] In some embodiments, the MSG1-based SI request is based on reserved preamble and / or random access channel (RACH) resources.
[0177] In some embodiments, MSG3-based SI does not require the reservation of RACH preamble, which is defined as RRCSystemInfoRequest message (MSG3).
[0178] In some embodiments, the UE learns whether to adopt MSG1-based or MSG3-based SI request by reading system information.
[0179] 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.
[0180] 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.
[0181] In some embodiments, SI requests from UEs in RRC connected state are not supported.
[0182] For example, referring to FIG1c , it includes:
[0183] Step S1101: The network device (Network) sends the MIB;
[0184] Step S1102: The network device sends SIB1;
[0185] Step S1103, the terminal (UE) sends a system information request (SystemInformationRequest);
[0186] In step S1104, the network device sends system information messages.
[0187] In some embodiments, in NR systems, if a terminal cannot obtain the MIB or SIB1, the terminal considers the current cell to be barred, and the barred period is up to 300 seconds. However, this is not suitable for cells that send SIB1 on demand, and it is necessary to clarify how to handle the scenario where the SIB is temporarily unavailable.
[0188] FIG2a is an interactive diagram of an information indication method according to an embodiment of the present disclosure. As shown in FIG2a, the present disclosure embodiment relates to a communication method for a communication system 100, the method comprising:
[0189] Step S2101: The terminal obtains first information.
[0190] In some embodiments, the terminal is 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, supporting requesting SIB1 from a network device through a request message.
[0191] In some embodiments, the terminal is a terminal in an RRC non-connected state, for example, a terminal in an RRC idle state or a terminal in an RRC inactive state.
[0192] In some embodiments, the terminal receives an MIB sent by a network device, and the information field contained in the MIB carries the first information; the terminal determines the first information based on the information field of the MIB.
[0193] Exemplarily, a bit in the MIB is used to indicate that the cell is an on-demand SIB1 required cell, or indicates that the cell is not barred for NES capable UE. For example, the bit may be a spare bit.
[0194] In some embodiments, the terminal receives second information from the first cell; and the terminal determines the first information based on the second information.
[0195] In some embodiments, the first cell is a cell capable of sending SIB1 on request (on-demand SIB1 required). That is, if the terminal needs to obtain SIB1 from the first cell, it needs to send a request message for requesting SIB1 to the network device corresponding to the first cell in order to obtain SIB1.
[0196] In some embodiments, the terminal receives second information from a third cell; the terminal determines the first information based on the second information. It should be noted that the third cell is a cell different from the first cell, and the third cell may be the second cell to which the terminal switches, which is not limited here.
[0197] In some embodiments, the second information and / or the third information may be stored in the terminal in advance.
[0198] In some embodiments, the terminal obtains stored information from other cells or the current cell, where the information indicates that the cell is an on-demand SIB1 required cell.
[0199] In some embodiments, the terminal receives third information indicating a physical cell identifier (PCI), and the terminal determines the first information based on the third information.
[0200] In some embodiments, the system reserves a PCI range or PCI list of cells that support SIB1 requests.
[0201] In some embodiments, the terminal receives fourth information indicating a frequency list, and the terminal determines the first information based on the fourth information.
[0202] In some embodiments, the system reserves a frequency list of cells that support SIB1 requests.
[0203] In some embodiments, the terminal determines a reference quantity, where the reference quantity is determined based on synchronization signal block SSB subcarrier offset ssb-SubcarrierOffset information of the MIB. The terminal determines the first information based on the reference quantity.
[0204] For example, the K corresponding to ssb-SubcarrierOffset in MIB SSB The value of is 0-23 (frequency range 1 FR1) and 0-11 (frequency range 2 FR2), and SIB1 is not obtained or the MIB information field is set to prohibited, and the first information is determined.
[0205] In some embodiments, the first information indicates that the first cell is a cell capable of sending SIB1 upon request.
[0206] In some embodiments, the network device sends first information to the terminal; wherein, the first information indicates that the first cell is a cell that can send SIB1 based on a request; the first result and the second result are used by the terminal to determine whether the first cell is in a prohibited state; the first result is used to indicate: whether the system information block 1 SIB1 is obtained or not obtained in the first cell; the second result is used to indicate: whether the first information is obtained or not obtained; the prohibited state is a state in which the terminal is prohibited from residing in the first cell.
[0207] Step S2102: The terminal determines whether the first cell is in a barred state.
[0208] In some embodiments, based on the first result, the terminal determines whether the first cell is in a barring state.
[0209] In some embodiments, the first result is used to indicate whether system information block 1 SIB1 is acquired or not acquired in the first cell.
[0210] In some embodiments, the prohibited state is a state in which the terminal is prohibited from camping on the first cell, and the first cell is a cell capable of sending SIB1 based on a request.
[0211] In some embodiments, the terminal determines that the SIB1 is not acquired in the first cell, and the terminal determines that the first cell is in the prohibited state.
[0212] In some embodiments, the terminal determines that the first cell is in the barred state, and the time for which the terminal determines that the first cell is in the barred state is a first duration.
[0213] Exemplarily, if the terminal obtains the MIB of a cell and attempts to obtain SIB1, if obtaining SIB1 fails, the terminal determines that the cell is in a barred state (barred), and the maximum time in the barred state is 300s.
[0214] In some embodiments, based on the first result and the second result, the terminal determines whether the first cell is in the barring state.
[0215] In some embodiments, the second result is used to indicate: whether first information is acquired or not acquired, and the first information indicates that the first cell is a cell capable of sending SIB1 based on a request.
[0216] In some embodiments, the terminal determines that the SIB1 is not acquired in the first cell and determines that the first information is acquired, and the terminal determines that the first cell is in the barred state;
[0217] In some embodiments, the terminal determines that the SIB1 is not acquired in the first cell and determines that the first information is acquired, and the terminal determines that the first cell is not in the prohibited state.
[0218] In some embodiments, the terminal determines that the time during which the first cell is in the prohibited state is a second duration; wherein the second duration is less than the first duration.
[0219] Exemplarily, if the terminal obtains the MIB of a cell and attempts to obtain SIB1, if obtaining SIB1 fails, the terminal determines that the cell is barred. If the terminal is able to obtain the cell as an on-demand SIB1 required cell, the UE determines that the maximum time for the cell to be barred is 3s (for example, 3s, in short, a value shorter than 300s).
[0220] Exemplarily, if the terminal obtains the MIB of a cell and attempts to obtain SIB1, if obtaining SIB1 fails, if the terminal can determine that the cell is an on-demand SIB1 required cell, the terminal determines that the cell is not barred, that is, not in a prohibited state.
[0221] Step S2103: The terminal determines the second cell.
[0222] In some embodiments, the second cell is determined based on first configuration information included in a master information block MIB.
[0223] In some embodiments, the second cell is a cell where the terminal resides.
[0224] In some embodiments, determining that the first configuration information indicates a first value, and determining that the second cell is a cell with the same frequency as the first cell;

[0227] In some embodiments, it is determined that the first configuration information indicates a second value, and it is determined that the second cell is a cell in a frequency layer different from that of the first cell.
[0228] Exemplarily, according to the configuration of intraFreqReselection in the MIB, if the configuration indicates a first value (for example, allowed), the terminal can select a neighboring cell with the same frequency as the cell or a cell on another frequency layer; if the configuration indicates a second value (for example, not allowed), the terminal cannot select a neighboring cell with the same frequency as the cell and can only select a cell on another frequency layer.
[0229] In some embodiments, the terminal camps on the second cell.
[0230] Step S2104: The terminal determines to exit the prohibited state.
[0231] In some embodiments, the terminal determines to camp on the second cell and obtains second configuration information, and determines to exit the barred state;
[0232] In some embodiments, the second configuration information is used to indicate that: in the first cell, information of SIB1 is obtained based on the request
[0233] In some embodiments, the second configuration information indicates a cell list, the cell list includes cells that support request-based acquisition of SIB1, and the cell list includes the first cell.
[0234] Exemplarily, if the terminal selects the second cell and obtains the configuration information about requesting SIB1 of the first cell that previously failed to obtain SIB1, or obtains a list of cells that support SIB1 requests through the neighboring cell, and the cell list includes the first cell, the terminal lifts the restriction on the cell being in the prohibited state for 300s.
[0235] Step S2105: The terminal obtains resources.
[0236] In some embodiments, the terminal obtains the resource.
[0237] In some embodiments, the resource is a resource used to request the SIB1.
[0238] In some embodiments, an MIB is received; wherein the MIB indicates a target cell, the target cell being a cell from which the terminal can obtain third configuration information, and the third configuration information is used to indicate: resources for requesting the SIB1.
[0239] Exemplarily, if the terminal cannot obtain SIB1 in the current cell and can determine that the cell is a cell that supports SIB1 request, the MIB can further indicate the target cell from which the terminal can obtain the resource configuration information of the requested SIB1, for example, PCI or frequency information, or PCI and frequency information.

[0327] In order to better understand the embodiments of the present disclosure, the present disclosure is further described below through some exemplary embodiments:
[0328] Example 1
[0329] Solution 1: For R19 NES capable UE, if the on-demand SIB1 required cell SIB1 cannot be obtained temporarily, the UE removes the cell barred restriction.
[0330] For example,
[0331] In some embodiments, R19 NES capable UE refers to a UE that supports on-demand SIB1 function.
[0332] In some embodiments, if a UE obtains the MIB of a cell and attempts to obtain SIB1, if obtaining SIB1 fails, the UE considers the cell to be barred, and the maximum barred time is 300 seconds.
[0333] In some embodiments, according to the configuration of intraFreqReselection in the MIB, if it is configured as allowed, the UE can select a neighboring cell with the same frequency as the cell, or a cell on another frequency layer; if it is configured as not allowed, the UE cannot select a neighboring cell with the same frequency as the cell, and can only select a cell on another frequency layer.
[0334] In some embodiments, if a cell is selected and configuration information about requesting SIB1 of a cell that previously failed to obtain SIB1 is obtained, or a list of cells supporting SIB1 request is obtained through neighboring cells and includes the cell, the UE removes the restriction barred 300 on the cell.
[0335] Example 2
[0336] Solution 2: For R19 NES capable UE, if the on-demand SIB1 required cell SIB1 cannot be obtained temporarily, the UE considers the cell to be cell barred for 3s.
[0337] In some embodiments, for R19 NES capable UE, it refers to a UE that supports on-demand SIB1 function.
[0338] In some embodiments, if the UE obtains the MIB of a cell and attempts to obtain SIB1, if obtaining SIB1 fails, the UE considers the cell to be barred. If the UE is able to obtain the cell as an on-demand SIB1 required cell, the maximum time for the UE to consider the cell to be barred is 3s (for example, 3s, in short, it is a value shorter than 300s).
[0339] In some embodiments, according to the configuration of intraFreqReselection in the MIB, if it is configured as allowed, the UE can select a neighboring cell with the same frequency as the cell, or a cell on another frequency layer; if it is configured as not allowed, the UE cannot select a neighboring cell with the same frequency as the cell, and can only select a cell on another frequency layer.
[0340] In some embodiments, if a UE obtains the MIB of a cell and attempts to obtain SIB1, if obtaining SIB1 fails, if the UE can obtain that the cell is an on-demand SIB1 required cell, the UE considers that the cell is not barred.
[0341] 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:
[0342] 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;
[0343] The UE obtains stored information from other cells or the current cell, indicating that the cell is an on-demand SIB1 required cell;
[0344] PCI, PCI rang or PCI list of cells reserved by the system to support SIB1 request;
[0345] Frequency list, the frequency list of cells reserved by the system to support SIB1 requests;
[0346] The KSSB value corresponding to the 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.
[0347] Example 3
[0348] Solution 3: MIB indication obtains resource configuration information of request SIB1.
[0349] In some embodiments, if the UE cannot obtain SIB1 in the current cell and can determine that the cell is a cell that supports SIB1 request, the MIB can further indicate the target cell from which the UE can obtain the resource configuration information of the requested SIB1, for example, PCI or frequency, or PCI and frequency.
