[0240] Figure 1a is a schematic diagram of the architecture of a communication system according to an embodiment of the present disclosure.

[0241] As shown in Figure 1a, the communication system 100 includes a terminal 101 and a network device 102.

[0242] In some embodiments, network devices include access network devices and core network devices.

[0243] In some embodiments, the terminal includes, but is not limited to, at least one of the following: mobile phone, wearable device, Internet of Things device, car with communication function, smart car, tablet computer, computer with wireless transceiver function, virtual reality (VR) terminal device, augmented reality (AR) terminal device, wireless terminal device in industrial control, wireless terminal device in self-driving, wireless terminal device in remote medical surgery, wireless terminal device in smart grid, wireless terminal device in transportation safety, wireless terminal device in smart city, and wireless terminal device in smart home.

[0244] In some embodiments, the access network device may be a node or device that connects a terminal to a wireless network. The access network device may include, but is not limited to, at least one of the following in a 5G communication system: evolved Node B (eNB), next-generation eNB (ng-eNB), next-generation Node B (gNB), node B (NB), home node B (HNB), home evolved node B (HeNB), radio backhaul device, radio network controller (RNC), base station controller (BSC), base transceiver station (BTS), base band unit (BBU), mobile switching center, base station in a 6G communication system, open RAN, cloud RAN, base station in other communication systems, and access node in a Wi-Fi system.

[0245] In some embodiments, the technical solutions of this disclosure can be applied to the Open RAN architecture. In this case, the interfaces between or within access network devices involved in the embodiments of this disclosure can be transformed into internal interfaces of Open RAN. The processes and information interactions between these internal interfaces can be implemented by software or programs.

[0246] In some embodiments, the access network device may be composed of a central unit (CU) and a distributed unit (DU). The CU may also be called a control unit. The CU-DU structure can separate the protocol layer of the access network device. Some of the protocol layer functions are centrally controlled by the CU, while the remaining part or all of the protocol layer functions are distributed in the DU and centrally controlled by the CU. However, this is not the only possibility.

[0247] In some embodiments, a core network device may be a single device comprising one or more network elements, or it may be multiple devices or a group of devices, each comprising all or part of the aforementioned one or more network elements. Network elements 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), or a Next Generation Core (NGC).

[0248] It is understood that the communication system described in this disclosure is for the purpose of more clearly illustrating the technical solutions of this disclosure, and does not constitute a limitation on the technical solutions provided in this disclosure. As those skilled in the art will know, with the evolution of system architecture and the emergence of new business scenarios, the technical solutions provided in this disclosure are also applicable to similar technical problems.

[0249] The following embodiments of this disclosure can be applied to the communication system 100 shown in FIG1a, or to some of the main bodies, but are not limited thereto. The main bodies shown in FIG1a are illustrative. The communication system may include all or some of the main bodies in FIG1a, or it may include other main bodies outside of FIG1a. The number and form of each main body are arbitrary. The connection relationship between the main bodies is illustrative. The main bodies may not be connected or may be connected. The connection can be in any way, it can be a direct connection or an indirect connection, it can be a wired connection or a wireless connection.

[0250] The embodiments disclosed herein 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), CDMA2000, Ultra Mobile Broadband (UMB), IEEE 802.11 (Wi-Fi), IEEE 802.16 (WiMAX), and IEEE 802.20, Ultra-Wideband (UWB), Bluetooth (a 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, systems utilizing other communication methods, and next-generation systems built upon them, etc. Furthermore, multiple systems can be combined (e.g., a combination of LTE or LTE-A with 5G).

[0251] With people's pursuit of speed, latency, high-speed mobility, energy efficiency, and the increasing diversity and complexity of business in future life, the 3rd Generation Partnership Project (3GPP) international standards organization began to develop 5G.

[0252] In some embodiments, the main application scenarios of 5G are: enhanced mobile broadband (eMBB), ultra-reliable and low-latency communications (URLLC), and massive machine-type communications (mMTC).

[0253] In some embodiments, eMBB still aims to provide users with multimedia content, services, and data, and its demand is growing rapidly. On the other hand, since eMBB may be deployed in different scenarios, such as indoors, urban areas, and rural areas, its capabilities and needs vary considerably. Therefore, generalizations cannot be made, and a detailed analysis must be conducted in conjunction with the specific deployment scenario.

[0254] In some embodiments, typical applications of URLLC include industrial automation, power automation, telemedicine operations (surgery), and / or traffic safety assurance.

[0255] In some embodiments, typical characteristics of mMTC include: high connection density, small data volume, latency-insensitive services, low module cost, and long service life.

[0256] In some embodiments, R15 introduces 5G technology. The energy consumption of a 5G base station is four times that of an LTE base station, so network energy saving is an important means for operators to reduce the cost of operating a 5G system.

[0257] In some embodiments, R16 introduces a wake-up signal (WUS) to power-efficient RRC_CONNECTED terminals. An offset preceding the on-duration of Connected Discontinuous Reception (C-DRX) in UE connected mode defines a duration for transmitting the WUS signal. During this WUS duration, the WUS signal, i.e., Downlink Control Information (DCI) 2-6, is transmitted, scrambled with a Power Saving-RNTI (PS-RNTI), to indicate whether the terminal should wake up and listen to the Physical Downlink Control Channel (PDCCH) during the subsequent UE C-DRX on-duration.

[0258] In some embodiments, R17 introduces paging WUS to save power for RRC_IDLE / INACTIVE terminals. This involves sending paging WUS, or paging early indication (PEI), at a certain point before the paging occasion (PO), to indicate whether the terminal should listen for paging scheduling information at that PO. The PEI is DCI 2-7, scrambled using PEI-RNTI.

[0259] In some embodiments, in 5G R18, network energy saving was addressed to reduce network power consumption. When the network enters energy-saving mode (NES mode), cells periodically refrain from transmitting and / or receiving at certain intervals; this is known as discontinuous transmission (DTX) or discontinuous reception (DRX). However, the standard agrees that the Master Indication Block (MIB), System Information Block (SIB), paging messages, and Random Access Channel (RACH) can be transmitted and received. The four supported NES functions are as follows, and are specified separately in the standard:

[0260] • SSB-less Scell ​​(secondary cell with fewer SSBs);

[0261] • Cell DTX / DRX;

[0262] • Antenna port adaptation;

[0263] • PDSCH transmission power adaptation.

[0264] In some embodiments, for network power saving methods of cell DTX or DRX, the network side configures the operating mode (pattern) of cell DTX or DRX through dedicated Radio Resource Control (RRC) signaling. This involves configuring a period, offset, and onduration duration. During the onduration, the cell is active and can receive and transmit data. Other times are inactive, and the network side, in principle, performs data reception and transmission. Except in special circumstances, such as paging, SSB, MIB, SIB, and RACH processes, these processes are unaffected and proceed normally.

[0265] In some embodiments, DCI 2-9 is a group common DCI used to notify the UE about the activation and deactivation of cell DTX and DRX. The R18 NES project also includes cell switch-off. Because cell DTX or DRX activation or cell switch-off can render NES-enabled terminals inoperable or unable to meet high-performance requirements, the terminal needs to switch to another cell. Therefore, the R18 NES project introduced Conditional Handover (CHO) for NES, i.e., Network Energy Saving (NES), and agreed to trigger handover based on a 1-bit DCI instruction. That is, if the NES CHO handover condition is met and a DCI handover instruction is received from the network side, the handover is executed. Currently, the DCI is DCI format 2-9, which reuses the DCI for cell DTX or DRX activation and deactivation.

[0266] In some embodiments, in the New Radio (NR) system broadcast, the content includes MIB, Remaining Minimum System Information (RMSI) (i.e., SIB1), and OSI (other SIBs).

[0267] 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 MIB. The multiplexing relationship between RMSI CORESET and SS / PBCH block resources includes three types: the UE obtains the resource location of the PDCCH based on the RMSI CORESET information in the Physical Broadcast Channel (PBCH), thereby further receiving RMSI.

[0268] For example, please refer to Figure 1b, the three relationships include:

[0269] Pattern 1: Time Division Multiplexing (TDM);

[0270] Pattern 2: Time Division Multiplexing (TDM) combined with Frequency Division Multiplexing (FDM);

[0271] Pattern 3: Frequency Division Multiplexing (FDM).

[0272] In some embodiments of NR, to conserve network resources and reduce the amount of system information broadcast by default by the base station, a request-based system broadcast transmission is proposed.

[0273] In some embodiments, all SIBs except MIB and SIB1 can be requested on demand. That is, the base station will only broadcast an SIB after receiving an SI request from the UE.

[0274] In some embodiments, SIB1 contains an indication of whether each SI is being broadcast, and the UE can learn which SIBs need to make SI requests by reading SIB1.

[0275] In some embodiments, the SI request method includes MSG1-based SI requests and MSG3-based SI requests.

[0276] In some embodiments, MSG1-based SI requests are based on reserved preamble and / or RACH resources.

[0277] In some embodiments, the MSG3-based SI does not require reserving a RACH preamble, which is defined as an RRCSystemInfoRequest message (MSG3).

[0278] In some embodiments, the UE determines whether to use an MSG1-based or MSG3-based SI request by reading system information.

[0279] In some embodiments, if the base station provides configuration information for the SI request, i.e., si-Request-Config, in the system information (SIB1), then the MSG1-based SI request is used; otherwise, the MSG3-based SI request is used.

[0280] In some embodiments, after receiving confirmation of the SI request, the UE receives the SI in the current modification period. The UE receives the SI until the modification period ends or until it knows that the SI has been received. If RACH fails during the SI request process, the subsequent behavior of the UE depends on the UE implementation.

[0281] In some embodiments, R15 does not support SI requests for UEs in the RRC_CONNECTED state.

[0282] For example, referring to Figure 1c, a method is provided that includes:

[0283] Step S1101: The network device sends a MIB to the user terminal (UE);

[0284] Step S1102: The network sends SIB1 to the terminal (UE);

[0285] Step S1103: The terminal sends a System Information Request to the network;

[0286] Step S1104: The network sends system information messages to the terminal.

[0287] In some embodiments, R19 discusses support for requesting SIB1, but pre-configured information is required for the UE to initiate the process of requesting SIB1. For example, configuration information for requesting neighbor cell SIB1 can be obtained from a neighboring cell.

[0288] In some embodiments, for an on-demand SIB1 cell in a standalone deployment (i.e., only this cell has coverage and no other cells have coverage), if a terminal powers on within the coverage area of ​​this cell and initiates an initial cell search, it will be unable to request the SIB of this cell because it cannot obtain the configuration information for requesting SIB1, thus ultimately leading to a coverage vulnerability.

[0289] Figure 2a is an interactive schematic diagram of a communication method according to an embodiment of the present disclosure. As shown in Figure 2a, the present disclosure relates to a communication method for a communication system 100, the method comprising:

[0290] Step S2101: The terminal determines the first resource.

[0291] In some embodiments, the first resource is a pre-configured time-domain and / or frequency-domain resource.

[0292] In some embodiments, the first resource is a time-domain and / or frequency-domain resource determined based on a synchronization signal block (SSB).

[0293] In some embodiments, the first resource includes pre-configured time-domain and / or frequency-domain resources and time-domain and / or frequency-domain resources determined based on the synchronization signal block (SSB).

[0294] In some embodiments, the first resource is used to send a first signal.

[0295] In some embodiments, the first signal is used to request the network device to send System Information Block SIB1.

[0296] In some embodiments, the first signal is transmitted based on the first resource determined by the time-domain and / or frequency-domain location of the synchronization signal block (SSB). For example, referring to FIG2b, the first resource may be a resource corresponding to an uplink transmission.

[0297] In some embodiments, the first resource is determined based on first information.

[0298] In some embodiments, the first information is SSB information, which is used to indicate the time-domain and / or frequency-domain resource location corresponding to the obtained SSB.

[0299] In some embodiments, the first information is received SSB information, which is used to indicate the time-domain and / or frequency-domain resource location corresponding to the SSB.

[0300] In some embodiments, the first information is received Master Signal Block (MIB) information, which indicates information associated with the time-domain and / or frequency-domain resource location for requesting the network device to send the SIB1.

[0301] In some embodiments, the first information is communication rule information, which is used to indicate: information associated with the time-domain and / or frequency-domain location for requesting the network device to send the SIB1.

[0302] In some embodiments, the MIB information is also used to indicate at least one of the following:

[0303] SIB1 in the cell is transmitting;

[0304] SIB1 in the cell is not transmitting;

[0305] The cell is a cell that sends SIB1 based on demand;

[0306] The cell is not a cell that sends SIB1 based on demand;

[0307] The cell is a cell that supports demand-based SIB1 transmission;

[0308] The cell does not support demand-based SIB1 transmission.

[0309] In some embodiments, the first information includes SSB information; the frequency domain resource location of the first resource is determined based on the frequency domain resource location indicated by the SSB information.

[0310] In some embodiments, the first information includes SSB information; the frequency domain resource location of the first resource is determined based on the frequency domain resource location indicated by the SSB information and a first offset.

[0311] In some embodiments, the first offset is the number of frequency domain resources between the frequency domain resource location of the first resource and the SSB.

[0312] For example, referring to 2c, based on the lowest PRB position (e.g., position a in Figure 2c) or the highest PRB position (e.g., position b in Figure 2c) of the frequency domain location of the obtained SSB, offset by x (corresponding to the first offset) PRBs, which can be upward or downward, to determine the frequency domain resource of the first resource. Alternatively, n PRBs can be configured based on protocol agreements or MIB information, where the n PRBs represent the number of PRBs for the frequency domain resource of the first resource.

[0313] In some embodiments, the first information includes the MIB information, which indicates a first reference location for determining the frequency domain resource location of the first resource.

[0314] In some embodiments, the first reference location may be at least one of the following:

[0315] The first frequency domain resource location is determined based on the frequency domain resources of the SSB;

[0316] The location of frequency domain resources associated with the control resource set CORSET0.

[0317] In some embodiments, the first resource is determined based on the first reference location.

[0318] In some embodiments, the first resource is determined based on the first reference position and the second offset.

[0319] In some embodiments, the second offset is the number of frequency domain resources that are spaced between the frequency domain resource location of the first resource and the first reference location.

[0320] In some embodiments, the first information includes master signal block (MIB) information; the frequency domain resource location of the first resource is determined based on the first reference location indicated by the MIB information.

[0321] In some embodiments, the first reference position is a position determined based on the frequency domain position of the SSB.

[0322] In some embodiments, the first information includes master signal block (MIB) information; the frequency domain resource location of the first resource is determined based on the first reference location and the second offset.

[0323] For example, referring to Figure 2d, if the MIB information configures the position of point A (corresponding to the first reference position), such as the number of PRBs offset from the lower boundary of the SSB relative to point A, point A can be determined based on this configuration. Point A can be the starting position of common PRB 0. The frequency domain position offset of point A by x PRBs is used as the starting position of the frequency domain of the first resource. This can be agreed upon by protocol or configured in the MIB information as n PRBs, with the starting position of these n PRBs beginning at the aforementioned point A position. These n PRBs represent the number of PRBs in the frequency domain resources included in the first resource.

[0324] In some embodiments, the first information includes master signal block (MIB) information; the frequency domain resource position of the first resource is determined based on the frequency domain position of the control resource set CORSET0 indicated by the MIB information (corresponding to the first reference position).

[0325] In some embodiments, the frequency domain resource location of the first resource is determined based on the frequency domain location of CORSET0 and the second offset.

[0326] In some embodiments, the second offset is the number of frequency domain resources that are spaced between the frequency domain resource location of the first resource and the second reference location in the frequency domain location associated with CORSET0.

[0327] In some embodiments, referring to Figure 2e, the frequency domain configuration of CORESET0 and the configuration information of the frequency domain position of the first resource in CORESET0 can be specified in the protocol. For example, it can be determined based on offset, such as x in the figure, which is the number of PRBs offset relative to the lowest boundary of CORESET0 as the starting position of the frequency domain position of the first resource. The bandwidth of the frequency domain of the first resource can be determined based on bandwidth, such as n in the figure.

[0328] In some embodiments, the first offset is determined based on the offset indicated by the MIB information.

[0329] In some embodiments, the second offset is determined based on the offset indicated by the communication rule information.

[0330] In some embodiments, the first offset is determined based on the offset indicated by the MIB information.

[0331] In some embodiments, the second offset is determined based on the offset indicated by the communication rule information.

[0332] In some embodiments, the number of PRBs contained in the first resource is determined based on the number of Physical Resource Blocks (PRBs) indicated by the MIB information.

[0333] In some embodiments, the number of PRBs contained in the first resource is determined based on the number of PRBs indicated by the communication rule information.

[0334] In some embodiments, the starting position of the first resource in the time domain is determined based on the time domain position of receiving the MIB.

[0335] In some embodiments, the number of symbols contained in the first resource in the time domain is determined based on communication rule information.

[0336] In some embodiments, the number of symbols contained in the first resource in the time domain is determined based on the symbol information indicated in the MIB information.

[0337] For example, the symbol position corresponding to the first resource is located at an offset of 'a' symbols relative to the last or first symbol of the received MIB. 'a' can default to 0, and its value can be fixed in the protocol or configured in the MIB information. For instance, m symbols can be fixed in the protocol or configured in the MIB information.

[0338] In some embodiments, the number of symbols is determined based on the subcarrier spacing corresponding to the SSB search.

[0339] In some embodiments, the sub-carrier spacing (SCS) of the first resource is the same as the SSB's SCS.

[0340] In some embodiments, the first resource includes a protection bandwidth portion, and resources other than the protection bandwidth portion are used to transmit the first signal.

[0341] In some embodiments, a guard band in the time and / or frequency domain is reserved at the location of the first resource. After removing a portion of the guard band, the remaining time and frequency resources are used for the transmission of the first signal.

[0342] Step S2102: The terminal sends a first signal to the network device.

[0343] In some embodiments, the network device receives a first signal sent by the terminal.

[0344] In some embodiments, the terminal sends a first signal to the network device to indicate a first sequence.

[0345] In some embodiments, the first sequence is used to determine that the first signal is for requesting the transmission of SIB1.

[0346] In some embodiments, the network device determines whether the first signal is used to transmit SIB1 based on a first sequence.

[0347] In some embodiments, the terminal sends a first signal with a first energy magnitude to the network device.

[0348] In some embodiments, the first energy magnitude is used to determine whether the first signal is used to request the transmission of SIB1.

[0349] In some embodiments, the network device determines whether the first signal is used to transmit SIB1 based on a first energy level.

[0350] Step S2103: The network device sends the first information to the terminal.

[0351] In some embodiments, the terminal receives first information sent by the network device.

[0352] In some embodiments, the first information is SIB1 or an indication of whether to send the SIB1.

[0353] In some embodiments, after receiving a first signal, the network device sends first information to the terminal.

[0354] In some embodiments, based on the second information, the terminal receives the first information sent by the network device.

[0355] In some embodiments, the terminal receives the first information sent by the network device based on predefined second information.

[0356] In some embodiments, the second information is used to indicate at least one of the following:

[0357] Radio Network Temporary Identifier (RNTI), which is different from System Information Radio Network Temporary Identifier (SI-RNTI);

[0358] Time-domain resources and / or frequency-domain resources used to receive the first information.

[0359] For example, the first information is received based on a system-defined RNTI (which may be different from SI-RNTI).

[0360] In some embodiments, the first information is received on a second resource determined based on the first resource.

[0361] In some embodiments, the UE receives the first information or SIB1 at a time-frequency resource location defined by the system, for example, at a time-frequency resource location determined relative to the target time-frequency resource location of the first resource, offset by x symbols, offset by y PRBs, and at a time-frequency resource location of m symbols and n PRBs.

[0362] In some embodiments, the second resource is determined based on the first resource, the third offset, and the fourth offset.

[0363] In some embodiments, the third offset is the number of frequency domain resources between the frequency domain resources of the first resource and the frequency domain resources of the second resource, and the fourth offset is the number of time domain resources between the time domain resources of the first resource and the time domain resources of the second resource.
