[0055] For ease of understanding, some content related to the embodiments of this application is described below:

[0056] I. Introduction to Network Energy Saving (NES) in Release 19 (R19)

[0057] Network energy saving is of great significance for environmental sustainability, reducing environmental impact (greenhouse gas emissions), and saving operating costs. With the popularization of 5G in various industries and geographical regions, to handle services and applications that require very high data rates (e.g., more advanced services and applications of Extended Reality (XR)), the network becomes more dense, using more antennas, larger bandwidths, and more frequency bands. The impact of 5G on the environment needs to be controlled, and new solutions need to be developed to improve network energy saving. For this purpose, the 3rd Generation Partnership Project (3GPP) has initiated projects on network energy saving in Release 18 (R18) and R19, and has formulated multiple energy-saving directions. One of them is the on-demand System Information Block 1 (SIB1) for IDLE / INACTIVE UEs, that is, SIB1 can be sent on demand according to the needs of UEs.

[0058] II. Introduction to RACH

[0059] 1. Triggering events of random access

[0060] The random access process is triggered by many events, specifically including the following triggering events:

[0061] Initial access from the Radio Resource Control (RRC) idle state;

[0062] RRC Connection Re-establishment procedure;

[0063] When the uplink (UL) synchronization status is "asynchronous" and the Small Data Transmission (SDT) process is ongoing, during the Radio Resource Control (RRC) connected state or the RRC inactive state, downlink (DL) or UL data arrival (DL or UL data arrival, during RRC_CONNECTED or during RRC_INACTIVE while SDT procedure is ongoing, when UL synchronization status is "non-synchronised");

[0064] When there are no Physical Uplink Control Channel (PUCCH) resources available for SR and the SDT procedure is ongoing, UL data arrival during RRC_CONNECTED or RRC_INACTIVE;

[0065] Scheduling Request (SR) failure;

[0066] Request by RRC upon synchronous reconfiguration (e.g. handover);

[0067] RRC Connection Resume procedure from RRC_INACTIVE;

[0068] To establish time alignment for a secondary TAG;

[0069] Request for Other SI;

[0070] Beam failure recovery;

[0071] Consistent UL LBT failure on Special Cell (SpCell);

[0072] SDT in RRC_INACTIVE;

[0073] Positioning purpose during RRC_CONNECTED requiring random access procedure, e.g., when timing advance is needed for UE positioning.

[0074] 2. Traditional 4-step random access

[0075] The random access procedure of the UE includes:

[0076] Contention-based random access procedure (4-step random access (4-step RACH)), as Figure 2a shown;

[0077] Non-contention-based random access procedure, as Figure 2b shown.

[0078] Among them, for the contention-based random access procedure, the UE sends Msg1 (random access request) to the network side. After receiving Msg1, the network side sends Msg2 (random access response (Random Access Response, RAR)) message to the UE, and this message carries uplink grant information. The UE generates a protocol data unit (Protocol Data Unit, PDU) according to the uplink grant in Msg2 by performing the Medium Access Control (MAC) layer packet assembly function, and stores the MAC PDU in the Msg3 buffer. Then the UE sends the MAC PDU in the Msg3 buffer through the Hybrid Automatic Repeat Request (HARQ) process. After receiving Msg3, the network side sends Msg4 (e.g., contention resolution identity) to the UE. The UE determines whether the contention resolution is successful after receiving Msg4. If successful, the random access procedure is successful; otherwise, the random access procedure is restarted. For the restarted random access procedure, when the UE receives the uplink grant in Msg2 again, the UE directly takes out the previously stored MAC PDU from the Msg3 buffer and sends it through the HARQ process. The UE clears the HARQ buffer for Msg3 transmission of the random access procedure after the random access procedure is completed.

[0079] For a CONNECTED UE, the Msg4 contention resolution verification is as follows: The uplink transmission scheduled by the Physical Downlink Control Channel (PDCCH) with the Cell Radio Network Temporary Identity (C-RNTI) is a new transmission.

[0080] For an IDLE / INACTIVE UE, the Msg4 contention resolution verification is as follows: The UE Contention Resolution Identity information in the UE Contention Resolution Identity MAC Control Element (CE) (UE Contention Resolution Identity MAC CE) received by the UE matches the first 48 bits of the UL Common Control Channel (CCCH) Service Data Unit (SDU) sent by the UE.

[0081] 3. Two-Step Random Access (2-Step RACH)

[0082] The above two-step random access includes a contention-based two-step random access process and a non-contention-based two-step random access process. Among them, the contention-based two-step random access process can be as Figure 3a shown, and the non-contention-based random access process is as Figure 3b shown. Specifically, it can include:

[0083] Step 0: The network side configures the two-step random access configuration information for the UE. For example, the preamble of MsgA, the Physical Random Access Channel (PRACH) resource, and the PUSCH resource of the MsgA payload.

[0084] Step 1: The UE triggers the 2-step RACH process. The UE sends the preamble through the Physical Random Access Channel (PRACH) and sends the MsgA payload to the network side through the MsgA PUSCH resource.

[0085] Step 2: The network side sends an acknowledgment message (MsgB) to the UE. If the UE fails to receive MsgB, the UE resends MsgA.

[0086] The transmission method provided by the embodiments of the present application will be described in detail below in conjunction with the accompanying drawings through some embodiments and their application scenarios.

[0087] Please refer to Figure 4 , Figure 4 which is a flowchart of a transmission method provided by the embodiments of the present application. This method can be executed by a terminal. As Figure 4 shown, it includes the following steps:

[0088] Step 401: The terminal sends a wake-up signal to the first base station through the MSGA PUSCH or MSG3 of the RACH process. The wake-up signal is used for the first cell of the first base station.

[0089] In this embodiment, the above wake-up signal (Wake UP Signal, WUS) can be used to request the first cell to transition from the first state to the second state. The transition from the first state to the second state includes at least one of the following: transitioning from an energy-saving state to a non-energy-saving state; transitioning from a state of not transmitting SIB1 to a state of transmitting SIB1; transitioning from an adaptive state in the PRACH time domain to a non-adaptive state in the PRACH time domain.

[0090] It should be noted that the above wake-up signal is only an example. That is, the signal used to request the first cell to transition from the first state to the second state is not limited to being called a wake-up signal and can also be called other names, such as a wake-up signaling, etc.

[0091] The above first cell can be any cell different from the second cell. The second cell can be the resident cell or serving cell of the terminal. The first base station is the base station to which the first cell belongs. The base station to which the second cell belongs can be the same base station as the first base station or can be a different base station.

[0092] The triggering event of the above RACH process can be an existing RACH triggering event or a triggering event defined by an existing protocol, such as an RRC connection re-establishment process, SDT of RRC_INACTIVE, etc.; or it can be a newly defined triggering event, such as the need for SIB1 or the need to send a wake-up signal. That is, the RACH process is triggered when the terminal needs SIB1 or needs to send a wake-up signal.

[0093] Exemplarily, when the triggering event of the above RACH procedure is an existing RACH triggering event, the terminal can send a wake-up signal to the first base station through the MSGA PUSCH or MSG3 of the RACH procedure when there is a need to send a wake-up signal and the above existing RACH triggering event is satisfied at the same time. For example, when the terminal has a need to send a wake-up signal, if the SDT of the triggering event RRC_INACTIVE that triggers the RACH procedure is also satisfied, the terminal can send a wake-up signal to the first base station through the MSGA PUSCH or MSG3 of the RACH procedure; or, the terminal can send a wake-up signal to the first base station through the MSGA PUSCH or MSG3 of the RACH procedure during the ongoing RACH procedure triggered by the above existing RACH triggering event when there is a need to send a wake-up signal. For example, during the ongoing RACH procedure triggered by the SDT of the triggering event RRC_INACTIVE, if the terminal has a need to send a wake-up signal, the terminal can send a wake-up signal to the first base station through the MSGA PUSCH or MSG3 of the RACH procedure; or, the terminal can send a wake-up signal to the first base station through the MSGA PUSCH or MSG3 of the RACH procedure when there is a need to send a wake-up signal and the above existing RACH triggering event is not satisfied at the same time.

[0094] The above method of sending a wake-up signal to the first base station through the MSGA PUSCH or MSG3 can, for example, indicate the wake-up signal by multiplexing existing Information Elements (IEs) or messages in the above MSGA PUSCH or MSG3. For example, the existing RRC Resume Request message can be multiplexed to indicate the wake-up signal. For example, the wake-up signal can be indicated by a new resume cause in the RRC Resume Request message, which means that the UE hopes the network will change from the first state to the second state; or, the wake-up signal can be indicated by newly defined IEs or messages in the above MSGA PUSCH or MSG3. For example, the wake-up signal can be indicated by a newly defined LCID.

[0095] Exemplarily, the terminal sends a wake-up signal to the first base station through the MSGA PUSCH or MSG3 of the RACH procedure. In the case that the first base station receives the above wake-up signal, it can switch the first cell of the first base station from the first state to the second state. Then, the terminal can access or camp on the above first cell, and the first cell provides services for the terminal. For example, when the terminal moves to the edge of the second cell and is close to the second cell, the terminal can send a wake-up signal to the first base station through the MSGA PUSCH or MSG3 of the RACH procedure. The first base station can, based on the above wake-up signal, switch the first cell from the first state to the second state. For example, it changes from the state of not sending SIB1 to the state of sending SIB1. Then, the terminal can access or camp on the above first cell to provide services for the terminal through the first cell, ensuring the quality of service for the terminal.

[0096] In an embodiment of the present application, the terminal sends a wake-up signal to the first base station through the MSGA PUSCH or MSG3 of the RACH procedure. Among them, the wake-up signal is used for the first cell of the first base station. That is, in this embodiment, when the terminal needs the service of the first cell, it can send a wake-up signal to the first base station through the MSGA PUSCH or MSG3 of the RACH procedure to quickly switch the first cell from the first state to the second state. This is beneficial to ensuring the quality of service for the terminal while taking into account network energy saving.

[0097] Optionally, the wake-up signal carries at least one of the following indications through the MSGA PUSCH or MSG3: Media Access Control Control Element (MAC CE), Logical Channel Identifier (LCID), Radio Resource Control (RRC) message.

[0098] Indicating the wake-up signal through the MAC CE, for example, can use the existing R bit (bit) of the MAC CE to indicate the wake-up signal, or can newly define the MAC CE to indicate the wake-up signal, etc.

[0099] Indicating the wake-up signal through the LCID, for example, can use the existing LCID to indicate the wake-up signal, or can newly define the LCID to indicate the wake-up signal.

[0100] To indicate the wake-up signal through the RRC message as described above, for example, a new resume cause of the RRC Resume Request or a new establishment cause of the RRC Setup Request can be used to indicate the wake-up signal, or spare bits in the existing RRC message can be used to indicate the wake-up signal, or a new IE can be added to the existing RRC message to indicate the wake-up signal, or a new RRC message can be defined to indicate the wake-up signal, etc.

[0101] In this embodiment, the wake-up signal is indicated by at least one of the MAC CE, LCID, and RRC message carried by the MSGA PUSCH or MSG3, which can reduce the change to the transmission of the MSGA PUSCH or MSG3 while ensuring the transmission of the wake-up signal.

[0102] Optionally, the terminal sends a wake-up signal to the first base station through the MSGA PUSCH or MSG3 in the RACH procedure, including:

[0103] The terminal sends a wake-up signal to the first base station through the MSGA PUSCH or MSG3 in the RACH procedure according to the first configuration information;

[0104] Among them, the first configuration information includes some or all of the second configuration information, the second configuration information is the configuration information related to the wake-up signal applied to the first cell, the second configuration information is related to the first information, and the first information includes at least one of the following: terminal type, first cause, first measurement result; the first cause is the reason for the network to transition from the first state to the second state, and the first measurement result includes cell measurement results or channel measurement results;

[0105] The transition from the first state to the second state includes at least one of the following: transitioning from an energy-saving state to a non-energy-saving state; transitioning from a state of not sending the system information block SIB1 to a state of sending SIB1; transitioning from an adaptive state in the time domain of the physical random access channel PRACH to a non-adaptive state in the time domain of PRACH.

[0106] In this embodiment, the above-mentioned second configuration information can be predefined by the protocol, configured by the network-side device, or determined by the terminal, etc.

[0107] The above first configuration information may include some or all of the above second configuration information. Exemplarily, when the above first configuration information only includes the configuration information corresponding to the above terminal in the second configuration information, the terminal may use the first configuration information to send a wake-up signal to the first base station through the MSGA PUSCH or MSG3 of the RACH procedure; when the above first configuration information not only includes the configuration information corresponding to the above terminal in the second configuration information, but also includes the configuration information corresponding to other terminals in the second configuration information, the terminal may obtain the configuration information corresponding to the terminal from the first configuration information, and based on the configuration information corresponding to the terminal, send a wake-up signal to the first base station through the MSGA PUSCH or MSG3 of the RACH procedure.

[0108] The above second configuration information is related to at least one of the terminal type, the first reason, and the first measurement result. For example, some content of the above second configuration information is related to at least one of the terminal type, the first reason, and the first measurement result, or all content of the above second configuration information is related to at least one of the terminal type, the first reason, and the first measurement result.

[0109] Among them, the above terminal type can be reasonably divided according to actual needs. For example, the above terminal type may include a gold UE and a common UE, or the above terminal type may include a UE with a first priority and a UE with a second priority, etc. The above first reason may include, but is not limited to, reasons for scheduling information of other system information, obtaining configuration related to SDT, etc., which require information in SIB1. The above first measurement result includes a cell measurement result or a channel measurement result. For example, a reference signal receiving power (RSRP) measurement result, a reference signal received quality (RSRQ) measurement result, etc., where the cell measurement result may include the measurement result of the first cell or the second cell.

[0110] Exemplarily, when the above first information includes the terminal type, the above second configuration information may include multiple sets of configuration information corresponding to different terminal types, or the above second configuration information may include multiple information fields corresponding to different terminal types, or the above second configuration information may include configuration information corresponding to a specific terminal type, etc. When the above first information includes the first cause, the above second configuration information may include multiple sets of configuration information corresponding to different first causes, or the above second configuration information may include multiple information fields corresponding to different first causes, or the above second configuration information may include configuration information corresponding to a specific first cause, etc.; when the above first information includes the first measurement result, the above second configuration information may include multiple sets of configuration information corresponding to different first measurement results, or the above second configuration information may include multiple information fields corresponding to different first measurement results, or the above second configuration information may include configuration information corresponding to a specific first measurement result, etc.

[0111] Exemplarily, when the above first information includes at least two of the terminal type, the first cause, and the first measurement result, the above second configuration information may include multiple sets of configuration information corresponding to different combinations of at least two of the above terminal type, the first cause, and the first measurement result. For example, if the above first information includes the terminal type and the first cause, and the terminal type includes terminal type A and terminal type B, and the first cause includes first cause A and first cause B, then the above second configuration information may include the first set of configuration information corresponding to terminal type A and first cause A, the second set of configuration information corresponding to terminal type B and first cause A, the third set of configuration information corresponding to terminal type A and first cause B, and the fourth set of configuration information corresponding to terminal type B and first cause B; or the above second configuration information may include multiple information fields corresponding to different combinations of at least two of the above terminal type, the first cause, and the first measurement result, etc.

[0112] In this embodiment, the second configuration information is related to at least one of the terminal type, the first cause, and the first measurement result, where the first cause is the reason for the network to switch from the first state to the second state, and the first measurement result includes a cell measurement result or a channel measurement result, which facilitates more accurate and flexible control of the terminal to send wake-up signals.

[0113] Optionally, the second configuration information includes at least one set of configuration information, and the at least one set of configuration information corresponds to at least one terminal type; or the second configuration information includes at least two sets of configuration information, and different configuration information in the at least two sets of configuration information corresponds to different terminal types.

[0114] In one embodiment, the second configuration information may include at least one set of configuration information corresponding to a specific terminal type. Among them, the specific terminal type may be predefined by the protocol or configured by the network-side device, etc. For example, if the terminal types include gold UEs and ordinary UEs, the second configuration information may only include one set of configuration information corresponding to the gold UEs, that is, the ordinary UEs do not have the configuration information related to the wake-up signal applied to the first cell.

[0115] In another embodiment, the second configuration information may include at least two sets of configuration information corresponding to different terminal types. For example, if the terminal types include gold UEs and ordinary UEs, the second configuration information may include the first set of configuration information corresponding to the gold UEs and the second set of configuration information corresponding to the ordinary UEs.

[0116] In some optional embodiments, the first set of configuration information may be superior to the second set of configuration information. For example, the transmission priority of the information (such as MAC CE) configured in the first set of configuration information for indicating the wake-up signal is higher than that of the information configured in the second set of configuration information for indicating the wake-up signal.

[0117] It should be noted that the level or priority of the above-mentioned gold UEs is higher than that of the ordinary UEs. In some optional embodiments, the UE type may be determined based on at least one of the UE information provided by the core network and the moving speed of the UE, etc. Among them, the UE information provided by the core network may include, but is not limited to, the level of the UE, the identifier of the gold UE, etc. For example, a UE with a moving speed greater than the speed threshold is an ordinary UE, and a UE with a moving speed less than or equal to the speed threshold is a gold UE.

[0118] Optionally, the second configuration information includes at least one set of configuration information, and the at least one set of configuration information corresponds to at least one first reason; or, the second configuration information includes at least two sets of configuration information, and different configuration information in the at least two sets of configuration information corresponds to different types of first reasons.

[0119] In one embodiment, the second configuration information may include at least one set of configuration information corresponding to a specific first reason. Among them, the specific first reason may be predefined by the protocol or configured by the network-side device, etc. For example, if the first reasons include the scheduling information for other system information and the need for SDT configuration, the second configuration information may only include one set of configuration information corresponding to the need for SDT configuration, or the second configuration information may only include one set of configuration information corresponding to the scheduling information for other system information.

[0120] In another embodiment, the second configuration information may include at least two sets of configuration information corresponding to different first reasons. For example, if the first reasons include scheduling information that requires other system information and SDT configuration, the second configuration information may include a first set of configuration information corresponding to the scheduling information that requires other system information and a second set of configuration information corresponding to the SDT configuration.

[0121] In some alternative embodiments, the first set of configuration information may be superior to the second set of configuration information. For example, the transmission priority of the information (such as MAC CE) configured in the first set of configuration information for indicating the wake-up signal is higher than the information configured in the second set of configuration information for indicating the wake-up signal.

[0122] Optionally, the second configuration information includes at least one set of configuration information, and the at least one set of configuration information corresponds to a first measurement result within at least one value range; or, the second configuration information includes at least two sets of configuration information, and different configuration information in the at least two sets of configuration information corresponds to first measurement results within different value ranges.

[0123] In one embodiment, the second configuration information may include at least one set of configuration information corresponding to a first measurement result within a specific value range. Among them, the specific value range may be predefined by the protocol or configured by the network-side device, etc. For example, the second configuration information may only include a set of configuration information corresponding to the RSRP / RSRQ measurement result greater than the first threshold, that is, only configure a set of configuration information related to the wake-up signal for the UE whose RSRP / RSRQ measurement result is greater than the first threshold.

[0124] In another embodiment, the second configuration information may include at least two sets of configuration information corresponding to first measurement results within different value ranges. For example, the second configuration information may include a first set of configuration information corresponding to the RSRP / RSRQ measurement result greater than the first threshold, and a second set of configuration information corresponding to the RSRP / RSRQ measurement result less than or equal to the first threshold; or, the second configuration information may include a first set of configuration information corresponding to the RSRP / RSRQ measurement result within the first value range, and a second set of configuration information corresponding to the RSRP / RSRQ measurement result within the second value range. Among them, each value in the first value range is greater than each value in the second value range.

[0125] In some alternative embodiments, the first set of configuration information may be superior to the second set of configuration information. For example, the transmission priority of the information (such as MAC CE) configured in the first set of configuration information for indicating the wake-up signal is higher than the information configured in the second set of configuration information for indicating the wake-up signal.

[0126] Optionally, the second configuration information includes second information for indicating that the wake-up signal is indicated by MSGA PUSCH or MSG3.

[0127] Exemplarily, an information field for indicating the indication manner of the wake-up signal may be defined. When the value of this information field is the first value, it indicates that the wake-up signal is indicated by MSGA PUSCH or MSG3. Among them, the above first value may be predefined by the protocol.

[0128] Optionally, the second information is specifically used to indicate that the wake-up signal is indicated by at least one of MAC CE, LCID, and RRC message in MSGA PUSCH or MSG3.

[0129] Exemplarily, the above second information may indicate indicating the wake-up signal by multiplexing the existing MAC CE, or may indicate indicating the wake-up signal by a newly defined MAC CE; or, the above second information may indicate indicating the wake-up signal by LCID. For example, it indicates indicating the wake-up signal by LCID 60 or indicating the wake-up signal by LCID 70, etc.; or, the above second information may indicate multiplexing the existing RRC message to indicate the wake-up signal, or may indicate indicating the wake-up signal by a newly defined RRC message.

[0130] Optionally, the second configuration information is provided with a valid time.

[0131] In this embodiment, the above valid time may be a time length, or may be a specific time period. For example, it may include at least two of start time, end time, and time length.

[0132] It can be understood that when the second configuration information is provided with a valid time, the above second configuration information is only valid within its valid time. For example, the terminal can only send the wake-up signal according to the first configuration information within its valid time.

[0133] In some optional embodiments, when the above second configuration information includes at least two sets of configuration information, each set of configuration information may be provided with a corresponding valid time; or some information elements in the second configuration information are provided with a valid time

[0134] Optionally, at least part of the content in the second configuration information is predefined by the protocol.

[0136] The terminal receives the first configuration information sent by the second base station.

[0137] In this embodiment, the above second configuration information may be configured by a network-side device, for example, a first base station or a core network device. After the network-side device configures the second configuration information, it may be sent by the first base station to the second base station, and then the second base station sends the first configuration information to the terminal based on the second configuration information.

[0138] Optionally, the terminal receiving the first configuration information sent by the second base station includes:

[0139] The terminal receives the first configuration information sent by the second base station through dedicated signaling;

[0142] Wherein, the above second base station may be the base station to which the resident cell or serving cell of the terminal belongs.

[0143] In one implementation, the terminal receives the first configuration information sent by the second base station through dedicated signaling. Exemplarily, the first configuration information may be sent by enhancing existing dedicated signaling. For example, the first configuration information may be sent using an RRC release (RRCRelease) message, an RRC release with suspend configuration (RRCRelease with suspendconfig) message, an RRC reconfiguration (RRCReconfiguration) message, an RRC resume (RRCResume) message, or an RRC setup (RRCSetup) message, etc.; or, the first configuration information may be sent by newly defined dedicated signaling.

[0144] In another implementation, the terminal may receive the first configuration information sent by the second base station through common signaling. For example, the first configuration information may be sent by enhancing existing common signaling messages. For example, the first configuration information may be sent using a SIB1 message, or a new common signaling message may be defined to send the first configuration information.

[0145] Optionally, the method further includes:

[0146] The terminal receives a first enabling indication sent by the second base station, where the first enabling indication is used to indicate enabling the first configuration information.

[0147] In this embodiment, the network-side device may enable the first configuration information through the first enabling indication.

[0180] After the terminal sends the wake-up signal to the first base station, if the first cell still does not change from the first state to the second state, the terminal sends the wake-up signal to the first base station again.
