Description

Technical Field

[0001] This application relates to the field of communication technology, and in particular to a method for requesting system information blocks, a UE, a network device, a communication system, a storage medium, and a computer program product. Background Technology

[0002] Currently, 5G networks have been deployed on a large scale. 5G networks require more antennas, greater bandwidth, and more frequency bands to handle high data rate services and applications. 5G networks consume a significant amount of energy, necessitating energy-saving solutions that are crucial for environmental sustainability, reducing greenhouse gas emissions, and saving operating costs. Energy costs in mobile networks constitute a large proportion of operators' total costs. A significant portion of mobile network energy consumption comes from the radio access network (RAN), which can be divided into two parts: 1. Energy consumption during data transmission or reception; 2. Energy consumption required to maintain the necessary operation of RAN equipment when data transmission or reception is not in progress. Currently, idle cells enter energy-saving mode to conserve energy, broadcasting only SSBs (Synchronization Signal Blocks) without transmitting or receiving other data. Therefore, idle cells can be detected by UEs, but UEs cannot access them. If a UE needs to access an idle cell, the idle cell needs to leave the power-saving mode. Since the information carried by the SSB sent by the idle cell is fixed, the UE cannot obtain the configuration information for sending a wake-up signal from the SSB sent by the idle cell and therefore cannot access the idle cell.

[0053] Figure 1 This is a flowchart illustrating some embodiments of the system information block request method according to this disclosure. Figure 1 The system information block request method shown is applied to the UE. For example... Figure 1 As shown, the request method for the system information block includes steps S101 and S102.

[0054] Step S101: Receive configuration information of the energy-saving cell, wherein the configuration information includes uplink wake-up signal configuration information or system information block SIB1 request configuration information.

[0055] In some embodiments, the UE (User Equipment) can be various terminal devices, such as mobile phones, tablets, mobile internet devices, wearable devices, and in-vehicle devices. The network equipment can be network-side equipment for various 5G, 6G, and other networks.

[0056] To reduce the number of signals that are online for extended periods, NR (New Radio) systems package the PBCH (Physical Broadcast Channel) and synchronization signals into a single SSB (Synchronization Signal Block) for use during the UE's initial cell search process. The SSB includes the PSS (Primary Synchronization Signal), the SSS (Secondary Synchronization Signal), and the physical broadcast channel.

[0057] In scenarios involving in-band / inter-band carrier aggregation, the UE establishes and maintains an RRC (Radio Resource Control) connection with the network. An energy-saving cell is a cell in energy-saving mode; it only broadcasts SSBs and does not transmit or receive other data. Energy-saving cells can also be cells that do not transmit SIB1 (SIB1-less Cell), dormant cells, inactive cells, or sleeping cells.

[0058] The UE can receive configuration information for energy-saving cells sent by a first cell, which may include an anchor cell, a second cell, etc. The second cell may be a cell that periodically sends SIB1 messages, etc. The UE receives SIB1 messages or SystemInformation messages sent by the first cell, etc. The SIB1 messages or SystemInformation messages carry configuration information for energy-saving cells, including uplink wake-up signal configuration information, SIB1 request configuration information, etc. The SIB1 messages and SystemInformation messages are existing messages.

[0060] The SIB1 request configuration information includes at least one of the following: the cell identifier of the energy-saving cell, the second resource used to request SIB1, the triggering condition for requesting SIB1, and the identifier of the cell that supports on-demand SIB1; the second resource includes at least one of the following: RA preamble, PRACH opportunity, uplink grant, etc.; the triggering condition for requesting SIB1 can be multiple triggering conditions.

[0061] Step S102: Send first information to the energy-saving cell or the first cell according to the configuration information of the energy-saving cell, in order to request the energy-saving cell to send SIB1 or enter the activation state.

[0062] In some embodiments, the UE may use various methods to generate and send first information based on the configuration information of the energy-saving cell, and trigger the energy-saving cell to send SIB1 by sending the first information, or trigger the energy-saving cell to leave the energy-saving mode, sleep mode, etc. and enter the active state.

[0063] The first information includes the Random Access (RA) preamble, SIB1 request information, etc.; the SIB1 request information includes the cell identifier or PCI (Physical Cell Identifier) ​​of the energy-saving cell from which the UE requests to send SIB1; the UE can carry the SIB1 request information by sending a Random Access Message Msg3 or an RRC message, etc.

[0064] The system information block request method disclosed herein enables a UE in an RRC idle state or an RRC inactive state to obtain uplink wake-up signal configuration information or SIB1 request configuration information, obtain the configuration information required to send a wake-up signal to an energy-saving cell, trigger the energy-saving cell to become a normal cell and start sending SIB1, so that the UE can quickly access the energy-saving cell and obtain good network service, achieving energy saving without affecting the user experience.

[0065] In some embodiments, the UE sends first information to the energy-saving cell or the first cell according to the uplink wake-up signal configuration information or the system information block SIB1 request configuration information, requesting the energy-saving cell to send SIB1 or enter the activation state (leave the energy-saving mode); the network side can know that a UE wants to access the energy-saving cell, and then decide whether to activate the energy-saving cell to provide network services for the UE, so as not to affect the user experience while saving energy.

[0066] By sending the first information through the first cell, the energy-saving cell does not need to send any information, including SSB, on the air interface; by sending uplink wake-up signal configuration information or SIB1 request configuration information to the base station corresponding to the first cell through the base station corresponding to the energy-saving cell, the UE can obtain the uplink wake-up signal configuration information in cross-base station scenarios, thus achieving the effect of waking up the energy-saving cell across base stations.

[0067] The UE receives the second information sent by the energy-saving cell or the first cell. The UE receives the RAR (RA Response), random access message Msg2 or Msg4, etc., sent by the energy-saving cell or the first cell. The second information is carried in the RAR, Msg2 or Msg4, etc.

[0068] The second information includes confirmation information or rejection information. Rejection information is used to instruct the energy-saving cell not to send SIB1. Confirmation information includes at least one of the following: confirmation of instruction to send SIB1, identification of the energy-saving cell, SIB1 transmission cycle, SIB1 transmission time, and frequency information for sending SIB1.

[0069] In some embodiments, the first base station corresponding to the energy-saving cell and the second base station corresponding to the anchor cell or the second cell are not the same base station. The first base station corresponding to the energy-saving cell can send uplink wake-up signal configuration information or SIB1 request configuration information to the second base station corresponding to the anchor cell or the second cell. The anchor cell or the second cell will send the received uplink wake-up signal configuration information or SIB1 request configuration information to the UE.

[0070] The UE can send first information to the anchor cell or the second cell, requesting the energy-saving cell to send SIB1 or enter an active state. The anchor cell or the second cell sends SIB request indication information or wake-up indication information to the energy-saving cell, which may include the first information. The energy-saving cell can use existing methods to generate confirmation information or rejection information based on the SIB request indication information or wake-up indication information and send it to the anchor cell or the second cell. The anchor cell or the second cell can use existing methods to generate second information based on the confirmation information or rejection information sent by the energy-saving cell and send the second information to the UE.

[0111] The first base station corresponding to the energy-saving cell sends the configuration information of the energy-saving cell to the second base station corresponding to the first cell. The configuration information of the energy-saving cell includes uplink wake-up signal configuration information or SIB1 request configuration information, etc.

[0112] The UE receives an SIB1 message or a SystemInformation message sent by the first cell. The SIB1 message or SystemInformation message carries configuration information for the energy-saving cell. The configuration information for the energy-saving cell includes uplink wake-up signal configuration information or SIB1 request configuration information. The uplink wake-up signal configuration information includes at least one of the following: the cell identifier of the energy-saving cell, the first resource used to wake up or activate the energy-saving cell, and the period for sending the first information; the SIB1 request configuration information includes at least one of the following: the cell identifier of the energy-saving cell, the second resource used to request SIB1, the triggering condition for requesting SIB1, and the identifier of the cell supporting on-demand SIB1.

[0113] In step S702, the UE sends first information to the first cell according to the configuration information to request the energy-saving cell to send SIB1 or enter the activation state.

[0114] The UE can use existing methods to send first information to the first cell according to the configuration information. The first information includes the random access RA preamble or SIB1 request information, etc. The SIB1 request information includes the cell identifier or physical cell identifier (PCI) of the energy-saving cell to which the UE requests to send SIB1, etc. The UE can carry the SIB1 request information by sending Msg3 or RRC messages, etc.

[0115] In step S703, the second base station corresponding to the first cell sends a wake-up indication message or an SIB1 request indication message to the first base station corresponding to the energy-saving cell. The wake-up indication message or SIB1 request indication message may include the first information.

[0116] In step S704, the first base station corresponding to the energy-saving cell sends a response message to the second base station corresponding to the first cell. The response message includes an acknowledgment message or a rejection message.

[0117] In step S705, the UE receives second information sent by the first cell. The second information includes confirmation or rejection information sent by the energy-saving cell, with the rejection information instructing the energy-saving cell not to send SIB1.

[0118] The UE receives RAR, Msg2, or Msg4 from the first cell, which carries second information. The second information includes an acknowledgment or rejection message from the energy-saving cell. The rejection message instructs the energy-saving cell not to transmit SIB1. The acknowledgment message includes at least one of the following: an indication to transmit SIB1, the identifier of the energy-saving cell, the transmission period of SIB1, the transmission time of SIB1, and the frequency information for transmitting SIB1. After the energy-saving cell sends a response message, it leaves the energy-saving mode and enters the active state to transmit SIB1.

[0119] The system information block request method in the above embodiments enables a UE in an RRC idle state or an RRC inactive state to obtain uplink wake-up signal configuration information or SIB1 request configuration information, and obtain the configuration information required to send a wake-up signal to the energy-saving cell, so as to trigger the energy-saving cell to send SIB1 or wake up the energy-saving cell. It can trigger the energy-saving cell to become a normal cell and start sending SIB1, so that the UE can quickly access the energy-saving cell and obtain good network service. While achieving energy saving, it improves the user experience and can improve data transmission efficiency and quality.

[0120] Figure 8 This is a flowchart illustrating another embodiment of the system information block request method according to this disclosure, applied to a network device; such as Figure 8 As shown, the request method for the system information block includes steps S801 and S802.

[0121] Step S801: Send the configuration information of the energy-saving cell to the UE. The configuration information of the energy-saving cell includes uplink wake-up signal configuration information or SIB1 request configuration information.

[0122] Step S802: Receive first information sent by the UE through the energy-saving cell or the first cell, wherein the first information is generated by the UE according to the configuration information of the energy-saving cell, and is used to request the energy-saving cell to send SIB1 or enter the activation state.

[0123] In some embodiments, the network device sends configuration information of the energy-saving cell to the UE through the first cell, or sends configuration information of the energy-saving cell to the first cell through the energy-saving cell. For example, the network device sends an SIB1 message or a SystemInformation message to the UE through the first cell, wherein the SIB1 message or SystemInformation message carries the configuration information of the energy-saving cell.

[0124] The energy-saving cell or anchor cell sends a second message to the UE, which includes an acknowledgment message or a rejection message. The rejection message is used to instruct the energy-saving cell not to send SIB1. For example, the first cell sends an SIB request indication message or a wake-up indication message to the energy-saving cell. The first cell generates the second message based on the acknowledgment message or the rejection message returned by the energy-saving cell and sends it to the UE.
