[0001] CROSS-REFERENCE TO RELATED APPLICATIONS

[0002] The present disclosure is based on and claims the priority of Chinese patent application with application number 2024101627413 and application date of February 4, 2024.

[0004] Currently, to provide users with high-speed data services, denser networks need to be deployed, with more antennas, greater bandwidth, and more frequency bands. This leads to a sharp increase in network power consumption. Most network energy consumption comes from the radio access network, so energy conservation in the radio access network is crucial for mobile networks. When a user equipment (UE) moves into an energy-saving cell, it can send a wake-up signal to the network, alerting the base station of the UE's arrival in the cell and broadcasting system information (such as SIB1) and other system information. However, in some cases, waking up the base station to broadcast SIB1 and / or other system information can cause unnecessary power consumption in the base station, impacting network energy conservation.

[0098] Before introducing the technical solutions of the embodiments of the present disclosure, the relevant technologies are first introduced.

[0099] Currently, to provide users with high-speed data services, denser networks must be deployed, with more antennas, greater bandwidth, and more frequency bands. This leads to a sharp increase in network power consumption. According to statistics, mobile network energy consumption accounts for 23% of operating expenses, with the majority of this energy consumption coming from the radio access network. Therefore, energy conservation in the radio access network is crucial for mobile networks.

[0100] Currently, network energy-saving technologies include the following four:

[0101] The first method is to introduce discontinuous transmission (DTX) and / or discontinuous reception (DRX) in the cell to establish a periodic energy-saving mechanism for the base station.

[0102] The second type, handover enhancement, involves handing over the user equipment (UE) to a neighboring target cell when network energy conservation is required in the serving cell. Based on the existing conditional handover triggering conditions, the corresponding conditional handover evaluation and handover are performed according to the network energy conservation configuration of the source or target cell.

[0103] The third type is SSB-less SCell: In the carrier aggregation (CA) scenario, the secondary cell (Scell) does not send SSBs. Synchronization and measurement are performed through the SSBs of the primary cell (PCell) or other SCells. When the UE has a need, a wake-up signal is sent to enable the SCell to send SSBs or activate the SCell.

[0104] The fourth type is to send the system message SIB1 on demand: when the cell is in energy-saving state, only the synchronization signal block (SSB) is sent, and SIB1 is not sent; when the UE has a need, the UE sends a wake-up signal to enable the cell to send SIB1.

[0105] In the related art, when an idle or inactive UE moves to a cell that does not send SSB or SIB1, it cannot normally receive the system information of the cell. One solution is for the UE to send a wake-up signal to the network side, so that the base station knows that a UE has arrived in this cell, and thus broadcasts system information (such as SIB1), and can further broadcast other system messages. The problem with this solution is that the idle or inactive UE may have only reselected the cell and has no need for uplink or downlink service data transmission. Therefore, waking up the base station to broadcast SIB1 and / or other system information will cause unnecessary power consumption of the base station, affecting the energy saving effect of the network.

[0106] Based on this, in an embodiment of the present disclosure, a first network device sends first information to a terminal; the first information represents information related to an energy-saving cell; wherein the first information includes one or more of the following: a related identifier of the energy-saving cell; time domain and / or frequency domain location information of the terminal receiving a paging message in the energy-saving cell; time domain and / or frequency domain location information of the terminal initiating random access in the energy-saving cell; a random access preamble code used by the terminal to initiate random access in the energy-saving cell; time domain and / or frequency domain location information of the terminal in sending a wake-up signal in the energy-saving cell; information used by the terminal to send a wake-up signal in the energy-saving cell.

[0107] 1 is a schematic diagram of an implementation flow of an information transmission method according to an embodiment of the present disclosure, which is applied to a first network device. The method includes step 101:

[0108] Step 101: Sending first information to a terminal; the first information represents information related to an energy-saving cell;

[0109] in,

[0110] The first information includes one or more of the following:

[0111] Relevant signs of energy-saving communities;

[0112] Location information in the time domain and / or frequency domain of the terminal receiving the paging message in the energy-saving cell;

[0113] Location information in the time domain and / or frequency domain when the terminal initiates random access in the energy-saving cell;

[0114] A random access preamble code used by the terminal to initiate random access in the energy-saving cell;

[0115] Location information of the terminal in the time domain and / or frequency domain at which the terminal sends the wake-up signal in the energy-saving cell;

[0116] The terminal sends information used by the wake-up signal in the energy-saving cell.

[0117] As an example, the first information may also be described as configuration information representing energy-saving cells.

[0118] As an example, the relevant identifier of the energy-saving cell may be a physical cell identifier (PCI, Physical Cell Identifier).

[0119] As an example, the time domain and / or frequency domain location information of the terminal receiving the paging message in the energy-saving cell may refer to pagingSearchSpace.

[0120] As an example, the time domain and / or frequency domain location information of the terminal initiating random access in the energy-saving cell may refer to RACH-ConfigCommon.

[0121] As an example, the random access preamble code used by the terminal to initiate random access in the energy-saving cell may be a specific codeword or a group of codewords.

[0122] As an example, the information used by the terminal to send the wake-up signal in the energy-saving cell may refer to a codeword or a sequence.

[0123] In some embodiments, the sending the first information to the terminal includes:

[0124] receiving the first information sent by the second network device;

[0125] The first information is sent to the terminal.

[0126] As a possible implementation manner, receiving the first information sent by the second network device may include: directly receiving the first information sent by the second network device.

[0127] That is, the second network device may directly send the first information to the first network device.

[0128] As another possible implementation, receiving the first information sent by the second network device may include:

[0129] receiving a SIB1 message broadcast by a second network device, wherein the SIB1 message carries the first information;

[0130] Parsing the SIB1 message to obtain the first information;

[0131] The first information is sent to the terminal.

[0132] As an example, optionally, taking the first network device and the second network device as base stations, the base stations transmit or exchange SIB1 messages on the Xn interface, where the SIB1 messages carry configuration information related to energy-saving cells.

[0133] That is, the SIB1 message broadcast by the second network device may be received through the Xn interface between the first network device and the second network device, thereby obtaining the first information according to the SIB1 message.

[0134] In some embodiments, the first network device includes a first CU and a first DU; the second network device includes a second CU and a second DU; and sending the first information to the terminal includes:

[0135] The second DU sends the first information to the second CU;

[0136] The second CU sends the first information to the first CU;

[0137] The first CU sends the first information to the terminal.

[0138] As a possible implementation manner, the second DU may directly send the first information to the second CU.

[0139] As another possible implementation, the second DU may broadcast a SIB1 message to the second CU; the SIB1 message carries the first information; and the second CU parses the SIB1 message to obtain the first information.

[0140] As an example, for the CU-DU separation architecture, it is assumed that the first network device includes a first CU and a first DU, and the second network device includes a second CU and a second DU. The second CU is represented by CU1, the second DU is represented by DU1, and the first CU is represented by CU2. DU1 sends the SIB1 message to CU1. The SIB1 message carries relevant configurations for the terminal to receive paging messages or send random access or send wake-up signals, that is, configuration information related to energy-saving cells; CU1 then sends it to CU2, and CU2 then sends it to the terminal such as UE through a broadcast message or an RRC release message.

[0141] In some embodiments, the sending the first information to the terminal includes:

[0142] Sending a broadcast message to the terminal; the broadcast message carries the first information;

[0143] or,

[0144] Send an RRC release message to the terminal, where the RRC release message carries the first information.

[0145] As an example, the first network device such as a base station may broadcast the received energy-saving cell-related configuration information in the system information, or carry the energy-saving cell-related configuration information in the RRC Release message that changes the UE state to idle or inactive.

[0146] In some embodiments, the method further comprises:

[0147] If the random access preamble code sent by the terminal is received, sending second information required for accessing the energy-saving cell to the terminal;

[0148] The second information is part or all of the remaining information in the SIB1 message except the first information.

[0149] That is to say, if the random access preamble code sent by the terminal is received, it is determined that the terminal needs to enter the connected state for uplink and / or downlink data transmission; and the second information required to access the energy-saving cell is sent to the terminal so that the terminal can establish an RRC connection with the energy-saving cell.

[0150] As an example, when the terminal such as UE has uplink and / or downlink data to send, the random access preamble code is sent at the configured time-frequency position to implicitly wake up the first network device to indicate that the terminal needs to enter a connected state for uplink and / or downlink data transmission.

[0151] As an example, after the first network device such as a base station receives the preamble code sent by a terminal such as a UE, it knows that the UE needs to enter a connected state for data transmission, and then sends the second information required for the UE to access the energy-saving (NES) cell, so that the UE can establish an RRC connection with the NES cell.

[0152] It should be noted that in the prior art, the SIB1 message is broadcast to the UE before random access (RA). In the embodiment of the present disclosure, the second information is sent to the terminal only after receiving the random access preamble code sent by the terminal, and the content included in the second information may be part or all of the remaining information in the SIB1 message excluding the content that has been sent to the UE before, that is, the first information.

[0153] In some embodiments, the method further comprises:

[0154] If the wake-up signal sent by the terminal is received, relevant configuration information for random access or the SIB1 message of the energy-saving cell is sent to the terminal.

[0155] That is to say, if the wake-up signal sent by the terminal is received, it is determined that the terminal needs to enter the connected state for uplink and / or downlink data transmission; and the relevant configuration information for random access or the SIB1 message required for the terminal to access the energy-saving cell is sent to the terminal, so that the terminal can establish an RRC connection with the energy-saving cell.

[0156] As an example, when the terminal such as UE has uplink and / or downlink data to send, the wake-up signal is sent at the configured time-frequency position to wake up the first network device to indicate that the terminal needs to enter a connected state for uplink and / or downlink data transmission.

[0157] As an example, after the first network device such as a base station receives a wake-up signal sent by a terminal such as a UE, it knows that the UE needs to enter a connected state for data transmission, and then sends the RA-related configuration information for the UE to perform random access or the SIB1 message required for the UE to access the NES cell, so that the UE can establish an RRC connection with the NES cell.

[0158] In some embodiments, the energy-saving cell is a neighboring cell of a cell where the terminal is currently camped;

[0159] In the case that there are multiple neighboring cells, the first information configured for the multiple neighboring cells is the same, or the first information configured for each energy-saving cell is independently configured.

[0160] As an example, the energy-saving cell may be a neighboring cell of the cell where a terminal such as a UE is currently residing; when there are multiple neighboring cells, the first information configured for the multiple neighboring cells is the same, or the first information of each (per) energy-saving cell is independently configured.

[0161] In some embodiments, the method further comprises:

[0162] In a case where the first information configured for the multiple neighboring cells is the same, a cell list is sent to the terminal; the cell list carries a related identifier of each cell in the multiple neighboring cells.

[0163] As an example, the cell list is used to indicate valid cell identities, and the first information configured for multiple cells in the cell list is the same.

[0164] The embodiments of the present disclosure have the following advantages:

[0165] (1) The first network device sends information related to the energy-saving cell to the terminal. In this way, after the terminal enters the energy-saving cell, the base station can be woken up only when the terminal has uplink and / or downlink data transmission requirements. Compared with the method in the related art of waking up the base station when the terminal has no uplink and / or downlink data transmission requirements, the power consumption of the base station can be saved, thereby improving the energy-saving effect on the network side.

[0166] Here, the first network device sends the relevant information required for receiving paging messages and initiating random access, i.e., the first information, to the terminal such as UE in advance. In this way, after the UE enters the energy-saving cell, it knows where to receive paging messages, send random access procedures or wake-up signals, so that when there is an uplink or downlink data transmission requirement, it can receive relevant system information and enter the connected state for data transmission.

[0167] (2) Since the UE will only send a random access procedure or a wake-up signal when uplink and / or downlink services arrive, or will only monitor the paging message when downlink data arrives, and initiate random access to wake up the base station when it is paged, it can effectively prevent the base station from being mistakenly woken up by a UE that is just passing through the cell and has no data transmission, and can effectively save energy on the network side.

[0168] 2 is a schematic diagram of an implementation flow of an information transmission method according to an embodiment of the present disclosure, which is applied to a terminal. The method includes step 201:

[0169] Step 201: Receive first information sent by a first network device; the first information represents information related to the energy-saving cell;

[0170] in,

[0171] The first information includes one or more of the following:

[0172] Relevant signs of energy-saving communities;

[0173] Location information in the time domain and / or frequency domain of the terminal receiving the paging message in the energy-saving cell;

[0174] Location information in the time domain and / or frequency domain when the terminal initiates random access in the energy-saving cell;

[0175] A random access preamble code used by the terminal to initiate random access in the energy-saving cell;

[0176] Location information of the terminal in the time domain and / or frequency domain at which the terminal sends the wake-up signal in the energy-saving cell;

[0177] The terminal sends information used by the wake-up signal in the energy-saving cell.

[0178] As an example, the relevant identifier of the energy-saving cell may be a physical cell identifier (PCI, Physical Cell Identifier).

[0179] As an example, the time domain and / or frequency domain location information of the terminal receiving the paging message in the energy-saving cell may refer to pagingSearchSpace.

[0180] As an example, the time domain and / or frequency domain location information of the terminal initiating random access in the energy-saving cell may refer to RACH-ConfigCommon.

[0181] As an example, the random access preamble code used by the terminal to initiate random access in the energy-saving cell may be a specific codeword or a group of codewords.

[0182] As an example, the information used by the terminal to send the wake-up signal in the energy-saving cell may refer to a codeword or a sequence.

[0183] In some embodiments, the first information is sent by the second network device to the first network device.

[0184] The first information is obtained by the first network device receiving a SIB1 message broadcasted by the second network device and parsing the SIB1 message; the SIB1 message carries the first information.

[0185] As an example, optionally, taking the first network device and the second network device as base stations, the base stations transmit or exchange SIB1 messages on the Xn interface, where the SIB1 messages carry configuration information related to energy-saving cells.

[0186] That is, the SIB1 message broadcast by the second network device may be received through the Xn interface between the first network device and the second network device.

[0187] In some embodiments, the first network device includes a first CU and a first DU; the second network device includes a second CU and a second DU; and receiving the first information sent by the first network device includes:

[0188] receiving the first information sent by the first CU;

[0189] The first information is sent by the second DU to the second CU; and the second CU is sent to the first CU.

[0190] As an example, the first information may be sent directly by the second DU to the second CU.

[0191] As an example, the first information may also be a SIB1 message broadcast by the second DU to the second CU; the SIB1 message carries the first information; and the second CU parses the SIB1 message to obtain the first information.

[0192] As an example, for the CU-DU separation architecture, it is assumed that the first network device includes a first CU and a first DU, and the second network device includes a second CU and a second DU. The second CU is represented by CU1, the second DU is represented by DU1, and the first CU is represented by CU2. DU1 sends the SIB1 message to CU1. The SIB1 message carries relevant configurations for the terminal to receive paging messages or send random access or send wake-up signals, that is, configuration information related to energy-saving cells; CU1 then sends it to CU2, and CU2 then sends it to the terminal such as UE through a broadcast message or an RRC release message.

[0193] In some embodiments, the receiving the first information sent by the first network device includes:

[0194] receiving a broadcast message sent by the first network device; the broadcast message carries the first information; or,

[0195] Receive an RRC release message sent by the first network device, wherein the RRC release message carries the first information.

[0196] As an example, the first network device such as a base station may broadcast the received energy-saving cell-related configuration information in the system information, or carry the energy-saving cell-related configuration information in the RRC Release message that changes the UE state to idle or inactive.

[0197] In some embodiments, the method further comprises:

[0198] In a case where the terminal reselects to the energy-saving cell, the terminal receives a paging message according to the time domain and / or frequency domain position information of the terminal in the energy-saving cell for receiving the paging message in the first information.

[0199] In some embodiments, the receiving the paging message according to the time domain and / or frequency domain location information of the terminal in the energy-saving cell receiving the paging message in the first information includes:

[0200] If the terminal detects the paging message sent to itself at a position in the time domain and / or frequency domain where the paging message is received, it is determined that downlink data has arrived.

[0201] That is, when a terminal such as a UE detects a paging message sent to itself, it indicates that downlink data has arrived.

[0202] In some embodiments, the method further comprises:

[0203] When the terminal has uplink and / or downlink data to be sent, sending the random access preamble to the first network device according to the time domain and / or frequency domain position information of the terminal initiating random access in the energy-saving cell in the first information;

[0204] The random access preamble is used to implicitly indicate that the terminal needs to enter a connected state to perform uplink and / or downlink data transmission.

[0205] As an example, when the terminal such as UE has uplink and / or downlink data to send, the random access preamble code is sent at the configured time-frequency position to implicitly wake up the first network device to indicate that the terminal needs to enter a connected state for uplink and / or downlink data transmission.

[0206] As an example, after the first network device such as a base station receives the preamble code sent by a terminal such as a UE, it knows that the UE needs to enter a connected state for data transmission, and then sends the second information required for the UE to access the energy saving (NES) cell, so that the UE can establish an RRC connection with the NES cell; wherein the second information is part or all of the remaining information in the SIB1 message except the first information.

[0207] Based on this, in some embodiments, the method further includes:

[0208] When the first network device receives the random access preamble sent by the terminal, receiving second information sent by the first network device;

[0209] The second information is part or all of the remaining information in the SIB1 message except the first information.

[0210] As an example, the second information represents information required by the terminal to access the energy-saving cell.

[0211] It should be noted that in the prior art, the SIB1 message is broadcast to the UE before random access (RA). In the embodiment of the present disclosure, the second information is sent to the terminal only after receiving the random access preamble code sent by the terminal, and the content included in the second information may be part or all of the remaining information in the SIB1 message excluding the content that has been sent to the UE before, that is, the first information.

[0212] In some embodiments, the method further comprises:

[0213] When the terminal has uplink and / or downlink data to be sent, sending the wake-up signal to the first network device according to the time domain and / or frequency domain position information of the terminal in the energy-saving cell for sending the wake-up signal and the information used by the terminal to send the wake-up signal in the energy-saving cell in the first information;

[0214] The wake-up signal is used to indicate that the terminal needs to enter a connected state to perform uplink and / or downlink data transmission.

[0215] As an example, when the terminal such as UE has uplink and / or downlink data to send, the wake-up signal is sent at the configured time-frequency position to wake up the first network device to indicate that the terminal needs to enter a connected state for uplink and / or downlink data transmission.

[0216] As an example, after the first network device such as a base station receives a wake-up signal sent by a terminal such as a UE, it knows that the UE needs to enter a connected state for data transmission, and then sends the RA-related configuration information for the UE to perform random access or the SIB1 message required for the UE to access the NES cell, so that the UE can establish an RRC connection with the NES cell.

[0217] Based on this, in some embodiments, the method further includes:

[0218] In a case where the first network device receives the wake-up signal sent by the terminal, the first network device receives configuration information related to random access of the terminal or the SIB1 message of the energy-saving cell sent by the first network device.

[0219] In some embodiments, the energy-saving cell is a neighboring cell of a cell where the terminal is currently camped;

[0220] In the case that there are multiple neighboring cells, the first information configured for the multiple neighboring cells is the same, or the first information configured for each energy-saving cell is independently configured.

[0221] As an example, the energy-saving cell may be a neighboring cell of the cell where a terminal such as a UE is currently residing; when there are multiple neighboring cells, the first information configured for the multiple neighboring cells is the same, or the first information of each (per) energy-saving cell is independently configured.

[0222] In some embodiments, the method further comprises:

[0223] In a case where the first information configured for the multiple neighboring cells is the same, a cell list sent by the first network device is received; the cell list carries a related identifier of each cell in the multiple neighboring cells.

[0224] As an example, the cell list is used to indicate valid cell identities, and the first information configured for multiple cells in the cell list is the same.

[0225] The embodiments of the present disclosure have the following advantages:

[0226] (1) The first network device sends information related to the energy-saving cell to the terminal. In this way, after the terminal enters the energy-saving cell, the base station can be woken up only when the terminal has uplink and / or downlink data transmission requirements. Compared with the method in the related art of waking up the base station when the terminal has no uplink and / or downlink data transmission requirements, the power consumption of the base station can be saved, thereby improving the energy-saving effect on the network side.

[0227] Here, the first network device sends the relevant information required for receiving paging messages and initiating random access, i.e., the first information, to the terminal such as UE in advance. In this way, after the UE enters the energy-saving cell, it knows where to receive paging messages, send random access procedures or wake-up signals, so that when there is an uplink or downlink data transmission requirement, it can receive relevant system information and enter the connected state for data transmission.

[0228] (2) Since the UE will only send a random access procedure or a wake-up signal when uplink and / or downlink services arrive, or will only monitor the paging message when downlink data arrives, and initiate random access to wake up the base station when it is paged, it can effectively prevent the base station from being mistakenly woken up by a UE that is just passing through the cell and has no data transmission, and can effectively save energy on the network side.
