[0001] CROSS-REFERENCE TO RELATED APPLICATIONS

[0002] This application claims priority to Chinese Patent Application No. 202410403768.7 filed in China on April 3, 2024, the entire contents of which are incorporated herein by reference. Technical Field

[0003] The present application belongs to the field of communication technology, and specifically relates to an information transmission method, apparatus, communication equipment and storage medium. Background Art

[0004] As technology advances, network communications must handle very high data rate services and applications (such as extended reality (XR) services), as well as more advanced services and applications. This results in denser networks, using more antennas, greater bandwidth, and more frequency bands. This consumes more network resources and, in turn, has a greater impact on the environment. Therefore, the environmental impact of technological development needs to be managed. Network energy conservation is crucial for environmental sustainability, reducing environmental impacts (such as greenhouse gas emissions), and saving operating costs.

[0005] To this end, a variety of network energy-saving solutions have been proposed. For example, network energy conservation can be achieved in the time, space, and frequency domains. Therefore, network-side devices can transition from a normal communication state (i.e., a non-energy-saving state) to an energy-saving state, achieving network energy conservation.

[0006] However, in some scenarios, the terminal needs to obtain certain necessary information from the network-side device in an energy-saving state to maintain synchronization with the network-side device. However, in the prior art, the network-side device does not provide this information when in an energy-saving state, resulting in the terminal being unable to maintain synchronization with the network-side device.

It should be noted that in the embodiment of the present application, only the base station in the NR system is used as an example for introduction, and the specific type of the base station is not limited.

[0060] To facilitate understanding of the information transmission method according to the embodiment of the present application, the following relevant contents are first introduced:

[0061] 1. Mapping rules for Synchronization Signal Block (SSB) to PRACH transmission occasion (PRACH Occasion, RO) in 5G NR

[0062] The configuration parameters of the physical random access channel (PRACH) resources and SSB-RO are configured in the system information block (SIB), for example, through SIB1, namely:

[0063] SIB1->ServingCellConfigCommon->UplinkConfigCommon->Initial Uplink Bandwidth Part (initialUplinkBWP)->Uplink Bandwidth Part (BWP-UplinkCommon)->Random Access Channel Common Configuration (rach-ConfigCommon)->RACH-ConfigCommon->Random Access Channel Generic Configuration (RACH-ConfigGeneric)->Physical Random Access Channel Configuration Index (prach-ConfigurationIndex), msg1-Frequency Division Multiplexing (msg1-FDM), msg1-Starting Frequency (FrequencyStart)); where msg1 represents a random access request message.

[0064] In NR, a cell can configure multiple frequency division multiplexing (FDM) ROs at a time domain location for PRACH transmission. The number of ROs that can be FDMed at a time can be: {1, 2, 4, 8}, which is configured by the higher-layer parameter msg1-FDM.

[0065] Among them, the random access preamble (Preamble) can only be transmitted on the time domain resources configured by the parameter prach-ConfigurationIndex and the frequency domain resources configured by the parameter msg1-FDM. RA ∈{0,1,…,M-1}, where M is equal to the high-level parameter msg1-FDM. At the time of initial access, the PRACH frequency domain resource n RA The PRACH frequency domain resource n is numbered in ascending order starting from the lowest frequency RO resource in the initial active uplink bandwidth part. Otherwise, the PRACH frequency domain resource n is RAThe RO resources are numbered in ascending order, starting from the lowest frequency RO resource within the active uplink bandwidth part. For example, in Figure 2, the number of FDM ROs at a time is 8 (i.e., msg1-FDM=8), and the RO resources are numbered from RO#0 to RO#7 in ascending order of frequency.

[0066] In NR, there's an association between Rolling Oscillators (ROs) and the actual synchronization signal / physical broadcast channel (SS / PBCH) blocks (SSBs) transmitted. ROs are associated with SSBs in the frequency domain (from low frequency to high frequency) and then in the time domain. A single SSB may be associated with multiple consecutive ROs, or multiple SSBs may be associated with a single RO (in this case, different SSBs correspond to different preambles). This is configured by the network using the parameters number of SSBs per RO (ssb-perRACH-Occasion) and number of contention-based preambles per SSB (CB-PreamblesPerSSB). For example, "oneEighth" represents an SSB associated with eight consecutive ROs, and "eight" represents eight SSBs associated with one RO. {n4, n8, n12, ...} represent the number of preambles associated with each SSB on a RO. For example, a value of n4 represents four preambles associated with each SSB on a RO, and a value of n8 represents four preambles associated with each SSB on a RO.

[0067] After all SSBs have completed one round of association with the RO, an SSB-RO mapping cycle is formed. An SSB-RO association period may include one or more SSB-RO mapping cycles. An SSB-RO association pattern period may include one or more SSB-RO association periods. The SSB-RO mapping is repeated based on the association pattern period, and the maximum association pattern period is 160ms.

[0068] Typically, a base station can use different beams to transmit different SSBs, where the number of SSBs is configured by the time domain position (ssb-PositionsInBurst) parameter of the SSB transmitted in the SSB burst. For the millimeter wave frequency band (FR2), the maximum number of SSBs is 64. The UE selects the RO / "RO and preamble combination" associated with the SSB with a good signal based on the strength of the received downlink beam / SSB, and sends a random access request message (Mg1). In this way, the network can determine the SSB selected by the UE based on the RO / "RO and preamble combination" of the received Preamble, and send a random access response (Mg2) on the downlink beam corresponding to the SSB to ensure the reception quality of the downlink signal.

[0069] Taking Figure 2 as an example, the number of Frequency Division Multiplexing (FDM) ROs at a given moment is 8, and the number of SSBs actually transmitted is 4, namely SSB#0, SSB#1, SSB#2, and SSB#3. Each SSB is associated with two ROs. If the UE determines to send PRACH / Mg1 on the RO corresponding to SSB#0, the UE selects an RO between RO#0 and RO#1 to send the PRACH.

[0070] Taking Figure 3 below as an example, the number of FDM ROs at a time is 2, and the number of SSBs actually transmitted is 8, namely SSB#0, SSB#1, ..., SSB#7, with every 2 SSBs associated with one RO. When multiple SSBs share a RO, the preamble sets associated with these multiple SSBs are different, that is, the same preamble cannot belong to the preamble sets associated with different SSBs at the same time: Taking RO#0 in Figure 3 as an example, RO#0 has a total of 60 preambles, of which preambles with indices 0 to 29 are associated with SSB#0, and preambles with indices 30 to 59 are associated with SSB#1.

[0071] It should be noted that each square in FIG3 represents an RO, not an SSB, and the labeled SSB refers to which SSB(s) the RO is associated with.

[0072] Before sending PRACH, the UE first selects a received beam (SSB) with a reference signal received power (RSRP) higher than the threshold based on the RSRP of the received SSB. If the RSRP of multiple SSBs is higher than the threshold, the terminal can select any SSB with RSRP higher than the threshold. If there is no SSB with RSRP higher than the threshold, the UE selects an SSB based on the implementation.

[0073] Based on the network (NW) configuration, the UE obtains the correspondence between the SSB and the RO. After selecting the SSB, the RO corresponding to the selected SSB is used as the RO for sending PRACH / Preamble / Msg1. If the selected SSB is associated with multiple ROs, the terminal can select one of the ROs for sending PRACH / Preamble / Msg1.

[0074] For example: In the example shown in Figure 2, assuming that the UE selects SSB#1, the UE can select one from RO#2 and RO#3 to send PRACH / Msg1; in the example shown in Figure 3, if the UE selects SSB#1, the UE can select the available RO closest to the current time among the ROs (RO#0 or RO#4) associated with SSB#1 to send PRACH / Msg1. In the selected RO, the UE selects a preamble from the preamble set associated with the selected SSB to send PRACH. As shown in Figure 3, one RO is associated with two SSBs, so in the available preamble set associated with the SSB in one RO, the preamble will be divided into two subsets, each subset corresponding to one SSB. The UE will select a preamble sequence in the preamble subset corresponding to the selected SSB for sending PRACH / Msg1.

[0075] 2. System Information Block Type 1 (SIB1)

[0076] The common search space set (CSS set) of the physical downlink control channel (Type0-PDCCH) of type 0 is used to monitor the SIB1 system message, corresponding to the downlink control information (DCI) scrambled with the system information radio network temporary identifier (SI-RNTI) in the primary cell in the master cell group (MCG), and is configured by the information element (IE): physical downlink control channel SIB1 configuration information (pdcch-ConfigSIB1) in the signaling master information block (MIB), or by IE: search space zero (serachSpaceZero) in the signaling physical downlink control channel common configuration information (PDCCH-ConfigCommon), or by IE: searchSpaceZero or SIB1 search space (searchSpaceSIB1) in the signaling PDCCH-ConfigCommon.

[0077] The CCE aggregation levels supported by the Type0-PDCCH CSS set and the number of candidate PDCCHs in each CCE aggregation level are shown in Table 1.

[0078] Table 1 Example of the number of candidate PDCCHs corresponding to the CCE aggregation level

[0079] 3. SSB and CORESET 0

[0080] There are three SSB and CORESET 0 multiplexing patterns, as shown in Figures 4 to 6. Pattern 1 uses time-division multiplexing (i.e., CORESET 0's frequency domain includes SSB), while Patterns 2 and 3 use frequency-division multiplexing (i.e., CORESET 0 and SSB exist in the same system frame). The difference between Pattern 2 and Pattern 3 is that, in the time domain, CORESET 0 in Pattern 2 is positioned slightly before SSB.

[0081] Among them, after the UE decodes the SSB, it can know the scheduling information of blind detection SIB1 at the specific time-frequency resource location.

[0082] IV. About SIB1

[0083] After detecting the PBCH, the terminal has completed downlink synchronization. Before performing uplink synchronization, the terminal needs to further receive SIB1 to obtain configuration information related to uplink synchronization.

[0084] SIB1 is transmitted in the Physical Downlink Shared Channel (PDSCH) and scheduled through the Physical Downlink Control Channel (PDCCH). The resource allocation range of PDSCH is within the frequency range of the initial bandwidth part (BWP).

[0085] Specifically, the PDCCH time-frequency domain resource allocation of SIB1 (that is, the DCI information for scheduling SIB1 is carried in CORESET0) is as follows:

[0086] (1) The SIB1 PDCCH is mapped to the CSS of the type 0-PDCCH;

[0087] (2) In the frequency domain, the CSS of Type 0-PDCCH is mapped in CORESET 0, and the frequency range of CORESET 0 is exactly the same as the initial BWP;

[0088] (3) The lower 4 bits of the signaling 'pdcch-ConfigSIB1' carried in the PBCH indicate the configuration of type 0-PDCCH CSS; the upper 4 bits indicate the configuration of CORESET 0.

[0089] Specifically, the PDSCH time-frequency domain resource allocation of SIB1 is as follows:

[0090] (1) Conventional PDSCH uses the Time Domain Resource Assignment (TDRA) table configured by Radio Resource Control (RRC), with the PDCCH indicating the index in the table for time domain resource allocation. However, since the RRC connection has not yet been established when the UE receives the SIB1 PDSCH, a default TDRA needs to be defined.

[0091] (2) The three multiplexing modes of CORESET0 and SSB correspond to three default TDRA tables;

[0092] (3) In the frequency domain, SIB1 performs frequency domain resource allocation within the initial access bandwidth and uses resource allocation type 1.

[0093] V. About SSB

[0094] In NR systems, the CD-SSB (cell-defining SSB) is defined as the SSB associated with SIB1 (Remaining Minimum System Information, RMSI). SIB1 defines the scheduling information for other SIBs and contains information for initial terminal access. The frequency location of the CD-SSB must be on the system synchronization grid.

[0095] NCD-SSB (non cell-defining SSB) is defined as an SSB that is not associated with SIB1. NCD-SSB can be used for secondary cell synchronization and can also be used as a measurement signal for terminal configuration. NCD-SSB is not necessarily located on the system synchronization grid. If NCD-SSB is located on the system synchronization grid, it can indicate the Global Synchronization Channel Number (GSCN) of the CD-SSB through the information it carries, as described below:

[0096] The PBCH channel data consists of 32 bits, of which bits 0 to 23 come from the RRC layer and bits 24 to 31 come from the physical layer (PHY).

[0097] Among them, PDCCH-ConfigSIB1 carries the information of CORESET#0 and search space 0;

[0098] The information carried by the PHY layer includes:

[0099] The lower 4 bits of the system frame number, a total of 4 bits;

[0100] 5ms half-frame number, 1 bit in total;

[0101] Beam identification number, or k SSB The highest bit (1 bit) and beam identification number (2 bits), a total of 3 bits;

[0102] 6. About k SSB

[0103] The subcarrier offset information field of SSB, ssb-SubcarrierOffset, is used to indicate the value k of the subcarrier offset between SSB and CORESET#0. SSBThe offset range includes 0-23 and 0-11 subcarriers, which are represented by 5 bits (4 bits are indicated by ssb-SubcarrierOffset and the highest bit is indicated by the PBCH PHY layer) and 4 bits, respectively, corresponding to the frequency ranges FR1 and FR2, where 4 bits can represent 16 values. SSB Only 12 bits (0 to 11) are used, 5 bits can represent 32 values, and the k of FR1 SSB Only 24 (0 to 23) are used, and the remaining values ​​are not used, which causes waste. SSB It is divided into two parts: normal k SSB (In FR1, k SSB is 0 to 23; in FR2, k SSB 0 to 11) and abnormal k SSB .

[0104] In FR1, if k SSB >23, or in FR2, if k SSB >11, all belong to abnormal k SSB , both indicate that the SSB does not have Type 0CSS, that is, the current SSB is not associated with SIB1. SSB The role is not limited to this. In order to allow UE to find CD-SSB quickly, abnormal k SSB It can also be used as an index, combined with the RMSI PDCCH configuration (Config) (i.e., PDCCH Config SIB1 of the MIB), to (indirectly) indicate the Global Synchronization Channel Number (GSCN) of the next SSB.

[0105] When k SSB >23(FR1) or k SSB >11(FR2), this value range is used to indicate NCD-SSB, and some values ​​can be used to indicate the GSCN of CD-SSB, as shown in Table 2, Table 3 and Figure 7 below.

[0106] Table 2 k under FR1 SSB Different values ​​of

[0107] Table 3 k in FR2 SSB Different values ​​of

[0108] In addition, when the value k SSB=31(FR1) or k SSB =15(FR2), the UE considers that there is no CD-SSB within a certain GSCN range.

[0109] 7. About Community A and Network Energy Saving (NES) Communities

[0110] Cell A (also referred to as a normal cell) refers to a cell that meets the first condition, where the first condition includes at least one of: being in a non-energy-saving state, periodically sending a first system information block SIB1, and the terminal currently being resident.

[0111] An NES Cell refers to a cell that meets the second condition, where the second condition includes at least one of being in an energy-saving state, not sending SIB1 periodically, not sending SIB1, and the terminal needs to be activated.

[0112] In the target cell of the UL WUS transmission, the UE may perform at least one of the following:

[0113] The UE sends a UL WUS to the NES cell;

[0114] The UE sends a UL WUS to cell A.

[0115] In addition, the transmission configuration of the UL WUS may be configured by at least one of the following:

[0116] The UE obtains UL WUS configuration from the NES Cell;

[0117] The UE obtains UL WUS configuration from cell A;

[0118] Other options are not ruled out.

[0119] Additionally, there may be UL WUS configurations in the following options:

[0120] Predefined UL WUS configuration (preconfigured);

[0121] Applicable to UL WUS configuration of multiple NES cells;

[0122] Applicable to UL WUS configuration of a single NES cell.

[0123] From the above, it can be seen that the UE may receive a common WUS configuration, ie, the WUS is applicable to multiple NES cells at the same time; or the UE may receive a dedicated WUS configuration, ie, the WUS is only applicable to a specific NES cell.

[0124] For the former case, the WUS configuration can include the number of WUS repetitions (e.g., the repetition number can be the maximum number of beams for multiple NES cells) and the WUS repetition resource configuration. For example, the WUS can transmit N times omnidirectionally, and all NES cells will still receive the signal using a defined beam weeping method.

[0125] In the latter case, the WUS configuration carries exclusive resource configuration, corresponding cell ID, beam, etc. For example, the WUS sends at least one WUS at the configured resource location using the configured beam, and the corresponding NES cell receives the WUS at the resource location using a specific beam.

[0126] 8. Media Access Control Protocol Data Unit (MAC PDU)

[0127] The MAC PDU consisting of the Media Access Control Random Access Response (MAC RAR) is shown in Figure 8. The RAR MAC PDU consists of one or more Media Access Control sub Protocol Data Units (MAC subPDUs) and an optional field (padding).

[0128] The MAC subPDU (subPDU) consists of the following components:

[0129] A Media Access Control (MAC) subheader with only a Backoff Indicator (BI) (may exist alone);

[0130] A MAC subheader with only a Random Access Preamble ID (RAPID) (i.e., an acknowledgment of an SI request, which may exist alone);

[0131] MAC subheader of RAR with RAPID MAC.

[0132] A MAC subPDU containing only the BI is placed at the beginning of the RAR MAC PDU (if the BI is included). A MAC subPDU with only RAPID (such as an ACK for an SI request) and a MAC subPDU with RAPID and a MAC RAR can be placed anywhere between the BI (if present) and the padding (if present) of the MAC subPDU.

[0133] From the structure of the RAR MAC PDU, it can be seen that if the gNB detects random access requests from multiple UEs on the same Physical Random Access Channel (PRACH) resource (same as the Random Access Radio Network Temporary Identity (RA-RNTI)), a single RAR MAC PDU can be used to respond to these access requests. Each response to a random access request (corresponding to a preamble index) corresponds to a RAR.

[0134] If multiple UEs send preambles on the same PRACH resource, the corresponding random access responses (Random Access Response, RAR) are multiplexed in the same RAR MAC PDU.

[0135] The RAR MAC PDU is transmitted on the downlink shared channel (DL-SCH) and is indicated by the PDCCH scrambled with the RA-RNTI. If all UEs using the same PRACH resource to send the preamble (the preamble does not necessarily need to be the same) monitor the same RA-RNTI scrambled PDCCH and receive the same RAR MAC PDU, different preamble indices correspond to different MAC RARs, that is, one MAC subPDU in the RAR MAC PDU.

[0136] Since the RAR MAC PDU can only be scrambled using one RA-RNTI, this also means that the RAR corresponding to the preamble sent using different PRACH resources (different time-frequency positions) cannot be multiplexed into the same RAR MAC PDU.

[0137] 9. It is also necessary to explain that:

[0138] "The network-side device sends X1" can be understood as "the network-side device sends X1 in the cell where it is located" or "the cell where the network-side device is located sends X1." For example, "the second network-side device sends X1" can be understood as "the second cell sends X1" or "the second network-side device sends X1 in the second cell." The second network-side device is located in the second cell.

[0139] “The network-side device receives X2” can be understood as “the network-side device receives X2 in the cell where it is located” or “the cell where the network-side device is located receives X2”; for example, “the second network-side device receives X2” can be understood as: the second cell receives X2, or the second network-side device receives X2 in the second cell;

[0140] "The terminal receives an X3 message sent by the network-side device" can be understood as "the terminal receives an X3 message sent by the cell where the network-side device is located" or "the terminal receives an X3 message sent by the network-side device in the cell where the network-side device is located". For example, "the terminal receives an X3 message sent by a second network-side device" can be understood as: the terminal receives an X3 message sent by the second cell, or the terminal receives an X3 message sent by the second network-side device in the second cell.

[0141] "The terminal sends X4 to the network-side device" can be understood as "the terminal sends X4 to the cell where the network-side device is located", or can also be understood as "the terminal sends X4 to the network-side device in the cell where the network-side device is located". For example, the terminal sends X4 to the second network-side device, which can be understood as: the terminal sends X4 to the second cell, or the terminal sends X4 to the second network-side device in the second cell.

[0142] Among them, X1 to X4 represent a type of information, signal or channel respectively.

[0143] In addition, the network side device being in the energy-saving state or the non-energy-saving state can be understood as: the cell where the network side device is located is in the energy-saving state or the non-energy-saving state.

[0144] The network-side device that meets the first condition is the network-side device located in Cell A;

[0145] The network-side device that meets the second condition is the network-side device located in the NES Cell.

[0146] Common WUS means that the wake-up signal (WUS) can be applied to multiple cells at the same time, that is, multiple cells can receive the WUS signal;

[0147] A dedicated wake-up signal (Dedicated WUS) means that the WUS is only applicable to a specific cell, and only the specific cell can receive the WUS signal.

[0148] The information transmission method provided in the embodiments of the present application is described in detail below through some embodiments and their application scenarios in combination with the accompanying drawings.

[0149] 9 , an embodiment of the present application provides an information transmission method, which may include the following steps 901 to 902:

[0150] Step 901: The terminal sends first information.

[0151] The first information is used to request or indicate at least one of the following:

[0152] At least one network-side device changes from an energy-saving state to a non-energy-saving state;

[0153] At least one network-side device in an energy-saving state sends target information; the target information is used for the terminal to maintain synchronization with the network-side device.

[0154] It should be noted that the network side device in the energy-saving state does not send periodic SIB1, or sends SIB1 at least once only after receiving the first information;

[0155] The network-side device in the non-energy-saving state will send all periodic signals, including periodic SIB1.

[0156] In addition, the network side device requested or indicated by the first information includes at least one network side device located in the NES Cell (ie, at least one network side device that meets the second condition, such as a network side device in an energy-saving state).

[0157] From this, it can be seen that the terminal can request or instruct all or part of multiple network-side devices to change from an energy-saving state to a non-energy-saving state; it can also request or instruct all or part of multiple network-side devices to send target information, and it can also request or instruct all or part of multiple network-side devices to change from an energy-saving state to a non-energy-saving state and send target information; it can also request or instruct part of multiple network-side devices to change from an energy-saving state to a non-energy-saving state, and the rest to send target information.

[0158] In addition, the state of the network-side device is used to indicate the state related to the transmission of the target information; wherein the state related to the transmission of the target information includes a periodic transmission state and an on-demand transmission or non-transmission state. When the network-side device is in a non-energy-saving state, the target information is periodically transmitted; when the network-side device is in an energy-saving state, the target information is transmitted on-demand or not transmitted to achieve energy saving. In addition, the terminal can send the first information to a second network-side device; the second network-side device can be a network-side device that meets the second condition (i.e., meets at least one of being in an energy-saving state, not transmitting SIB1 periodically, not transmitting SIB1, and the terminal needs to be activated). In this case, the terminal can directly send the first information to the network-side device that needs to transition to a non-energy-saving state and / or transmit the target information; or the second network-side device can be a network-side device that meets the first condition (i.e., meets at least one of being in a non-energy-saving state, periodically transmitting SIB1, and the terminal is currently resident). In this case, the terminal can send the first information to the network-side device that meets the first condition, causing it to notify the network-side device that meets the second condition to transition to a non-energy-saving state and / or transmit the target information.

[0159] It can be understood that the above-mentioned first information can also be called WUS.

[0160] Step 902: The terminal receives second information.

[0161] The second information includes at least one of the target information and the specific information for indicating feedback or response to the first information; that is, the network side device can send only the target information, or only the specific information, or both the target information and the specific information.

[0162] It should be noted that when the second information does not include the specific information (that is, the network side device only sends the target information), the target information can also be considered as a feedback or response to the first information. For example, if the terminal receives the target information of a certain network side device, it means that the network side device has successfully received the first information; if the terminal does not receive the target information of a certain network side device, it means that the network side device has not successfully received the first information.

[0163] Among them, the terminal sends the above-mentioned first information, requesting or instructing at least one of the following: at least one network side device changes from an energy-saving state to a non-energy-saving state, and at least one network side device in an energy-saving state sends target information; then the network side device requested or instructed by the first information can execute at least one of the following: determine whether to change to a non-energy-saving state, and send the second information (that is, send the target information and at least one of the specific information used to indicate feedback or response to the first information).

[0164] That is, the network-side device requested or instructed by the first information may send only the specific information, or may send only the target information, or may send both the specific information and the target information.

[0165] In addition, the feedback or response of the first information can be used to indicate at least one of the reception status of the first information (such as successful reception (ACK), unsuccessful reception (NACK)) and the sending status of the target information (such as resource information).

[0166] It is understandable that the above-mentioned specific information may also be referred to as a wake-up signal response (WUS Response) or a wake-up signal feedback (WUS feedback).

[0167] It can be seen from the above steps 901 to 902 that in an embodiment of the present application, the terminal can send a first information to request or indicate at least one of the following: at least one network side device changes from an energy-saving state to a non-energy-saving state, and at least one network side device in an energy-saving state sends target information, and the target information is used to maintain synchronization between the terminal and the network side device; thereby receiving the second information sent by the network side device, the second information includes the target information and at least one of the specific information used to indicate feedback or response to the first information.

[0168] It can be seen that in an embodiment of the present application, the terminal can send a first message to request or instruct at least one network-side device to change from an energy-saving state to a non-energy-saving state and send at least one item of target information; thereby, the corresponding network-side device can change from an energy-saving state to a non-energy-saving state to provide the target information to the terminal, or it can provide the target information to the terminal without changing the state; in addition, the terminal can also receive feedback or response to the first information sent by the network-side device to determine the reception status of the first information and provide a basis for the terminal to receive the target information. Therefore, an embodiment of the present application provides a feasible solution for the terminal to obtain the above-mentioned target information from the network-side device in the energy-saving state, so that the terminal can maintain synchronization with the network-side device.

[0169] Optionally, the time when the terminal receives the second information (i.e., at least one of the specific information and the target information) includes at least one of the following items A-1 to A-6:

[0170] Item A-1: ​​First time unit; it is understood that the first time unit may be a predefined or preconfigured time unit; the time unit may include at least one of a time slot and a symbol; for example, the terminal receives the second information in a predefined or configured time slot or symbol; it should be noted that when WUS is simultaneously effective for multiple cells (possibly including Cell A and possibly NES cells), the terminal may receive WUS Responses (i.e., WUS feedback) sent by all NES cells at the same time;

[0171] The first time unit includes at least one of the following:

[0172] The time unit at which the terminal sends the first information;

[0173] The next time unit after the terminal sends the first information;

[0174] The time unit of the moment after the terminal sends the first information for the first duration;

[0175] The next time unit after the first duration of time when the terminal sends the first information;

[0176] The time unit in which the downlink control channel corresponding to the synchronization signal block SSB associated with the first information is located.

[0177] Therefore, it can be seen that the terminal can receive the second information in the time unit at which the first information is sent. It should be noted that, when WUS is effective for multiple cells (possibly including Cell A and possibly NES Cell) at the same time, multiple cells can receive WUS by beam sweeping. The time when different cells receive WUS may be different, so the time when different cells send WUS Response (i.e., WUS feedback) may also be different. Therefore, the time when the terminal receives WUS Response (i.e., WUS feedback) sent by different cells may be different.

[0178] The terminal may also receive the second information at a time unit next to the time when the terminal sends the first information;

[0179] The terminal may also receive the second information at a time unit after the first time duration of sending the first information;

[0180] The terminal may also receive the second information at a next time unit after the first time duration of sending the first information;

[0181] The terminal may also receive the second information in the time unit where the downlink control channel corresponding to the SSB associated with the first information is located.

[0182] The downlink control channel may include a Type 0 PDCCH corresponding to the SSB index.

[0183] Item A-2: K1 consecutive time units starting from the first time unit;

[0184] It can be seen from this that the terminal can receive the second information for K1 consecutive time units starting from the time unit at which the terminal sends the first information;

[0185] The terminal may also receive the second information in a continuous K1 time units starting from the next time unit at the moment when the terminal sends the first information;

[0186] The terminal may also receive the second information in a continuous K1 time units starting from the time unit at which the first time duration elapses after the terminal sends the first information;

[0187] The terminal may also receive the second information in a continuous K1 time units starting from the next time unit after the first time length of the moment when the terminal sends the first information;

[0188] The terminal may also receive the second information in K1 consecutive time units starting from the time unit where the downlink control channel corresponding to the synchronization signal block (SSB) associated with the first information is located.

[0189] It is understandable that the values ​​of K1 in the several cases described here may be the same or different.

[0190] K1 can be predefined by the protocol or configured on the network side.

[0191] Item A-3: time after the first timer expires; for example, the terminal starts the first timer after sending a WUS, and receives a WUS Response (i.e., WUS feedback) after the first timer expires; the starting point or duration of the first timer may be agreed upon by the protocol or configured on the network side;

[0192] Item A-4: The time period corresponding to the second timer; for example, after the terminal sends a WUS, the terminal monitors the WUS Response (i.e., WUS feedback) within the time period corresponding to the second timer. The starting point or duration of the second timer may be agreed upon by the protocol or configured on the network side.

[0193] Item A-5: The time period corresponding to the first predetermined window (i.e., the time period included in the predetermined time window); for example, monitoring the WUS Response (i.e., WUS feedback) within the first predetermined window after the terminal sends the WUS. The starting point or duration of the first predetermined window may be agreed upon by the protocol or configured by the network.

[0194] Item A-6: A specific position within a first specific time unit (ie, at least one predetermined time unit); for example, the terminal monitors the WUS Response (ie, WUS feedback) in the first M symbols of a slot, or the last M symbols of a slot.

[0195] From the above, it can be seen that the terminal only needs to monitor the second information during the specified time (ie, at least one of the above A-1 to A-6), which reduces the duration or number of monitoring and is conducive to reducing terminal energy consumption.

[0196] Optionally, the second information (i.e., at least one of the specific information and target information) is carried in at least one of the following Q-1 to Q-13:

[0197] Q-1: SSB;

[0198] Q-2: SIB1;

[0199] Q-3: Type 0 physical downlink control channel (Type 0 PDCCH);

[0200] Q-4: Random access response physical downlink control channel (Msg2 PDCCH);

[0201] Q-5: Random access response physical downlink shared channel (Msg2 PDSCH);

[0202] Q-6: Paging Physical Downlink Control Channel (Paging PDCCH);

[0203] Q-7: Paging Physical Downlink Shared Channel (Paging PDSCH);

[0204] Q-8: Contention Resolution Message Physical Downlink Control Channel (Msg4 PDCCH);

[0205] Q-9: Contention Resolution Message Physical Downlink Shared Channel (Mg4 PDSCH);

[0206] Q-10: Message B Physical Downlink Control Channel (MsgB PDCCH);

[0207] Item Q-11: Message B Physical Downlink Shared Channel (MsgB PDSCH);

[0208] Item Q-12: A signal dedicated to transmitting the second information;

[0209] Q-13: A channel dedicated to transmitting the second information.

[0210] Among them, carrying the second information in the existing channel (ie, items Q-1 to Q-11 above) can reuse some existing bits or resources to avoid new overhead; however, the flexibility is worse and the information that can be carried is limited.

[0211] Carrying the second information in a dedicated channel (i.e., items Q-12 to Q-13 above) is more flexible and can carry more information, but it requires designing a new channel and introduces additional overhead.

[0212] It should be noted that Type 0 PDCCH refers to the PDCCH transmitted on CORESET#0; in addition, for the above-mentioned Type 0 PDCCH, the position of the monitor occasion (MO) is determined relative to the WUS; optionally, some fields can be set to invalid (Invalid) to indicate the WUS Response, for example, the frequency domain resource allocation (FDRA) can be Invalid to indicate that this is the WUS Response (ie, WUS feedback).

[0213] It can be understood that the target information is carried in any one of SSB and SIB1, which can be understood as the target information including at least one of SSB and SIB1.

[0214] Optionally, the terminal receives the second information (i.e., at least one of the specific information and the target information), including:

[0215] The terminal receives the second information according to the first configuration information;

[0216] The first configuration information includes at least one of the following:

[0217] The transmission resource of the second information, the number of repeated transmissions of the second information, and the repeated transmission resource of the second information.

[0218] It can be seen from this that the terminal can receive the second information according to at least one of the configured transmission resources, the number of repeated transmissions, and the repeated transmission resources of the second information.

[0219] Optionally, the first configuration information satisfies at least one of the following:

[0220] At least part of the information in the first configuration information is carried in the configuration information of the first information; for example, the configuration information of the WUS configured by the NES Cell or CellA to the terminal may carry at least one of the transmission resources, the number of repeated transmissions, and the repeated transmission resources of the second information;

[0221] At least part of the first configuration information is carried in an SSB; wherein the SSB may include at least one of an SSB sent by Cell A and an SSB sent by an NES cell;

[0222] At least part of the first configuration information is agreed upon through a protocol.

[0223] Among them, through the first configuration information, the terminal can know in advance where to receive or monitor the second information, thereby saving energy consumption.

[0224] Optionally, the second information (i.e., at least one of the specific information and target information) includes at least one of the following items B-1 to B-13:

[0225] Item B-1: the cell identifier or cell identifier list of the network-side device that sends the second information; that is, the identifier or cell identifier list of the cell where the network-side device that sends the second information is located;

[0226] Item B-2: the cell identifier or cell identifier list of the network-side device that sends the target information; that is, the identifier or cell identifier list of the cell where the network-side device that sends the target information is located;

[0227] Item B-3: the cell identifier or cell identifier list of the network-side device that successfully receives the first information; that is, the identifier or cell identifier list of the cell of the network-side device that successfully receives the first information;

[0228] Item B-4: an indication of whether the first information is successfully received;

[0229] Optionally, the indication of unsuccessful reception of the first information (ie, NACK) may be represented by setting certain fields of the existing PDCCH to specific values, for example, setting FDRA to Invalid, indicating that the first information was not successfully received.

[0230] Optionally, the content of the second information can be expressed by setting certain fields of the existing PDCCH to specific values ​​and further repurposing other fields. For example, FDRA is set to Invalid. When the value of FDRA is Invalid, different values ​​of other fields (such as the TDRA field) can indicate successful reception of the first information (ACK) or unsuccessful reception of the first information (NACK).

[0231] Item B-5: Instruction on whether to continue monitoring the target information;

[0232] Item B-6: the time-frequency domain resource location of the target information; wherein the target information here may include an on-demand SIB1;

[0233] It should be noted that when the second information includes the time-frequency domain resource location of the target information, the terminal can know when to start receiving the target information and which frequency domain resources to use to receive the target information, which can avoid the terminal repeatedly sending the first information and causing waste of resources and energy.

[0234] Item B-7: time-frequency domain resource location of the physical downlink control channel PDCCH for scheduling the target information;

[0235] Item B-8: The period of the target information; wherein the target information here may include on-demand SIB1;

[0236] Item B-9: a period of the PDCCH for scheduling the target information;

[0237] Item B-10: number of transmissions of the target information; wherein the target information here may include on-demand SIB1;

[0238] Item B-11: the number of transmissions of the PDCCH scheduling the target information;

[0239] Item B-12: Scheduling information related to the target information transmission; wherein the target information here may include on-demand SIB1;

[0240] Item B-13: related scheduling information of the PDCCH that schedules the target information; the scheduling information may include at least one of a coding modulation method and a redundant version number.

[0241] It should be noted that upon receiving the second message, the terminal can stop repeatedly sending the first message, saving energy. Furthermore, the terminal can use the instructions in the second message to determine when to start receiving system information, ensuring it can camp on the appropriate cell. If the terminal does not receive the second message, it may frequently send the first message, wasting energy. Furthermore, in the long run, synchronization with the energy-saving cell may be lost.

[0242] Optionally, the information type of the second information includes at least one of the following:

[0243] Physical layer messages, physical layer signals, and higher layer messages;

[0244] The physical layer message (or physical layer signal) includes at least one of the following:

[0245] Sequence, physical layer excitation signal, downlink control information DCI, PDCCH;

[0246] The high-level message includes at least one of the following:

[0247] Radio Resource Control (RRC) messages;

[0248] Media Access Control Control Element (MAC CE);

[0249] Media Access Control Protocol Data Unit (MAC PDU);

[0250] Random Access Response (Random Access Response, RAR).

[0251] It should be noted that when the information type of the second information is a sequence, different sequences may represent different meanings (i.e., representing different contents in the second information, such as whether the first information is successfully received), for example, different meanings may be represented by indexes of different sequences, or, for example, different cyclic shift values ​​may be used to represent different meanings;

[0252] Alternatively, when the information type of the second information is a physical layer excitation signal, different meanings can be expressed by the intensity of the physical layer excitation signal, for example, by detecting the relevant energy intensity. When the intensity exceeds a predefined threshold, it indicates that the first information is received successfully, otherwise the reception fails.

[0253] Alternatively, different meanings can be expressed through DCI;

[0254] Alternatively, different meanings may be expressed through PDCCH.

[0255] When the information type of the second information is a high-layer message, the second information can be transmitted through at least one of RRC, MAC CE, MAC PDU, and RAR.

[0256] For example, the second information may be transmitted using a modified RAR MAC PDU. Specific implementations may include at least one of the following:

[0257] This is achieved by modifying the definition of relevant fields in the existing RAR MAC PDU (for example, using the uplink grant (UL Grant) related fields in the RAR MAC PDU to carry the second information);

[0258] A subPDU is added after the last subPDU of the RAR MAC PDU to carry the second information.

[0259] It should be noted that the above-mentioned RAR MAC PDU can be called MAC PDU (RAR).

[0260] Alternatively, a new MAC PDU or MAC CE may be introduced to transmit the second information; for example, a new logical channel identifier (LCID) or extended logical channel identifier (eLCID) may be introduced to specifically indicate that the associated MAC PDU or MAC CE is used to transmit the second information;

[0261] Alternatively, a new RRC parameter may be introduced to transmit the second information. Optionally, when the information type of the second information includes at least one of DCI and PDCCH, the second information is scrambled using a specific Radio Network Temporary Identity (RNTI).

[0262] That is, if the second information is downlink control information (DCI) or a PDCCH, a specific RNTI, such as WUS-RNTI, may be used for scrambling. For example, if a terminal uses a specific RNTI (such as WUS-RNTI) to descramble the received DCI, a terminal that does not know the specific RNTI cannot decrypt the second information.

[0263] Optionally, the method further includes:

[0264] When the terminal receives the second information (i.e., at least one of the specific information and the target information), the terminal determines a target resource according to the second information, and receives or blindly detects a target object through the target resource;

[0265] wherein the target resource is indicated in the second information;

[0266] The target resource includes at least one of time domain resources, frequency domain resources, and beam information;

[0267] The target object includes at least one of a PDCCH corresponding to the target information and the target information (eg, on-demand SIB1).

[0268] Optionally, the PDCCH corresponding to the target information is a SIB1 PDCCH (ie, Type 0 PDCCH); wherein the SIB1 PDCCH includes scheduling information required for on-demand SIB1 transmission.

[0269] It can be seen from this that if the second information exists (that is, the network side device sends the second information) and the terminal receives the second information, the terminal can perform at least one of the following:

[0270] Based on the information carried in the received second information, the terminal uses a specific time-frequency domain resource position, specific frequency domain resources, and specific beam information to receive / blind detect the SIB1 PDCCH (the specific time-frequency domain resource position and beam information described herein may be specified in the second information);

[0271] Based on the information carried in the received second information, the terminal uses a specific time-frequency domain resource position, specific frequency domain resources, and specific beam information to receive / blind detect on-demand SIB1.

[0272] Optionally, the method further includes:

[0273] In one of the following situations C-1 to C-4, the terminal performs a first behavior:

[0274] Item C-1: The specific information exists (the network-side device sends the specific information or there is a network-side device that sends the specific information), but the terminal does not receive the specific information sent by the first network-side device; wherein the first network-side device includes at least one of the second network-side devices that sends the specific information;

[0275] Item C-2: the specific information exists, and the specific information of the first network-side device received by the terminal indicates that the first information was not successfully received;

[0276] Item C-3: The specific information exists, and the specific information of the first network-side device received by the terminal indicates not to send the target information;

[0277] Item C-4: The specific information does not exist (i.e., the network-side device does not send the specific information, or there is no network-side device that sends the specific information), and the terminal does not receive the target information sent by the first network-side device;

[0278] The first behavior includes at least one of the following items D-1 to D-10:

[0279] Item D-1: confirming that the first network-side device is barred or barred for a second duration; that is, the terminal believes that the first network-side device or the cell where the first network-side device is located prohibits the terminal from accessing the first network-side device for a second duration (a fixed duration);

[0280] Item D-2: resending the first information at least once;

[0281] Item D-3: resending the first information to the first network-side device at least once;

[0282] Regarding items D-2 and D-3, if the terminal still does not receive the specific information after retransmitting the first information N times (for example, N is the maximum number of retransmissions), it is considered that the first network-side device is disabled.

[0283] Item D-4: Increase the power for sending the first information; for example, introduce a power step (power_step), and increase the power of the first information once, that is, add power_step to the power of the last first information transmission.

[0285] Item D-6: Waiver of receiving the specific information;

[0292] Item D-10: Send the first information to the network side device that meets the first condition, where the first condition includes at least one of being in a non-energy-saving state, periodically sending the first system information block SIB1, and the terminal currently being resident.

[0293] Exemplarily, for a case where the specific information exists but the terminal does not receive the specific information sent by the first network side device, or a case where the specific information exists and the specific information of the first network side device received by the terminal indicates that the first information is not successfully received, or a case where the specific information exists and the specific information of the first network side device received by the terminal indicates that the target information is not sent, the terminal may perform at least one of the following:

[0297] The power of sending the first information is increased; for example, a power step (power_step) is introduced, and the power of the first information is increased once, that is, power_step is added on the basis of the power of the last first information transmission.

[0298] abandoning the reception of the target information;

[0299] waive the right to receive the specific information;

[0303] The first information is sent to a network side device that meets a first condition, where the first condition includes at least one of being in a non-energy-saving state, periodically sending a first system information block SIB1, and the terminal currently being resident.

[0313] 10 , an embodiment of the present application provides an information transmission method, which may include the following steps 1001 to 1002:

[0314] Step 1001: The second network side device receives first information.

[0315] The first information is used to request or instruct at least one of the following: at least one network-side device transitions from an energy-saving state to a non-energy-saving state; and at least one network-side device in an energy-saving state sends target information, where the target information is used to synchronize the terminal with the network-side device. The network-side device requested or indicated by the first information includes at least one network-side device located in an NES Cell (i.e., at least one network-side device that meets the second condition).

[0316] In addition, the first information may be sent by the terminal. That is, the terminal may request or instruct all or some of the multiple network-side devices to switch from an energy-saving state to a non-energy-saving state; may request or instruct all or some of the multiple network-side devices to send target information; may request or instruct all or some of the multiple network-side devices to switch from an energy-saving state to a non-energy-saving state and send target information; or may request or instruct some of the multiple network-side devices to switch from an energy-saving state to a non-energy-saving state, while the remaining devices send target information.

[0317] It should be noted that the status of the network side device is used to indicate the status related to the sending of the target information; wherein, the status related to the sending of the target information includes a periodic sending status and an on-demand sending or non-sending status. When the network side device is in a non-energy-saving state, the target information is sent periodically; when the network side device is in an energy-saving state, the target information is sent on demand or not sent to achieve energy saving.

[0318] In addition, the second network-side device may be a network-side device that satisfies the second condition (i.e., satisfies at least one of being in an energy-saving state, not sending SIB1 periodically, not sending SIB1, and the terminal needs to be activated). In this case, the terminal may directly send the first information to the network-side device that needs to transition to a non-energy-saving state and / or send target information.

[0319] Alternatively, the second network side device may be a network side device that satisfies the first condition (i.e., satisfies at least one of being in a non-energy-saving state, periodically sending SIB1, and the terminal currently residing), that is, the terminal may send a first message to the network side device that satisfies the first condition, so that the network side device that satisfies the second condition may notify the network side device that satisfies the second condition to switch to a non-energy-saving state and / or send target information.

[0320] It can be understood that the first information can also be called WUS.

[0321] Step 1002: The second network-side device sends second information according to the first information.

[0322] The second information includes at least one of the target information and specific information for indicating feedback or response to the first information; that is, the second network side device can send only the target information, or only the specific information, or both the target information and the specific information.

[0323] It should be noted that when the second information does not include the specific information (that is, the second network side device only sends the target information), the target information can also be considered as a feedback or response to the first information. For example, if the terminal receives the target information of a certain network side device, it means that the network side device has successfully received the first information; if the terminal does not receive the target information of a certain network side device, it means that the network side device has not successfully received the first information.

[0324] Among them, the terminal sends the above-mentioned first information, requesting or instructing at least one of the following: at least one network side device changes from an energy-saving state to a non-energy-saving state, and at least one network side device in an energy-saving state sends target information, and the target information is used to keep the terminal and the network side device synchronized; then the network side device requested or instructed by the first information can execute at least one of the following: determine whether to change to a non-energy-saving state, and send second information (that is, send target information and at least one of specific information used to indicate feedback or response to the first information).

[0325] That is, the network-side device requested or instructed by the first information may send only the specific information, or may send only the target information, or may send both the specific information and the target information.

[0326] In addition, the feedback or response of the first information can be used to indicate at least one of the reception status of the first information (such as successful reception (ACK), unsuccessful reception (NACK)) and the sending status of the target information (such as resource information).

[0327] It is understandable that the above-mentioned specific information may also be referred to as a wake-up signal response (WUS Response) or a wake-up signal feedback (WUS feedback).

[0328] It can be seen from the above steps 1001 to 1002 that in an embodiment of the present application, the second network side device can receive the first information, wherein the first information is used to request or indicate at least one of the following: at least one network side device changes from an energy-saving state to a non-energy-saving state, and at least one network side device in an energy-saving state sends target information, and the target information is used to keep the terminal and the network side device synchronized; thereby enabling the second network side device to send the second information, and the second information includes the target information and at least one of the specific information for indicating feedback or response to the first information.

[0329] It can be seen that in an embodiment of the present application, the terminal can send a first message to request or instruct at least one network-side device to change from an energy-saving state to a non-energy-saving state and send at least one item of target information; thereby, the corresponding network-side device can change from an energy-saving state to a non-energy-saving state to provide the target information to the terminal, or it can provide the target information to the terminal without changing the state; in addition, the terminal can also receive feedback or response to the first information sent by the network-side device to determine the reception status of the first information and provide a basis for the terminal to receive the target information. Therefore, an embodiment of the present application provides a feasible solution for the terminal to obtain the above-mentioned target information from the network-side device in the energy-saving state, so that the terminal can maintain synchronization with the network-side device.

[0330] Optionally, the time at which the second network-side device sends the second information (i.e., at least one of the specific information and the target information) includes at least one of the following items E-1 to E-6:

[0331] Item E-1: Second time unit; the second time unit may be a predefined or preconfigured time unit; the time unit may include at least one of a time slot and a symbol; for example, the second network-side device sends the second information in a predefined or configured time slot or symbol; it should be noted that if WUS is simultaneously effective for multiple cells (possibly including Cell A or an NES cell), all cells may send WUS Response (i.e., WUS feedback) at the same time;

[0332] The second time unit includes at least one of the following:

[0333] The time unit at which the second network-side device receives the first information;

[0334] The next time unit after the second network side device receives the first information;

[0335] The time unit of the moment after the second network side device receives the first information for a third time period;

[0336] The next time unit after the second network side device receives the first information for a third time period;

[0337] The time unit in which the downlink control channel corresponding to the synchronization signal block SSB associated with the first information is located.

[0338] It should be noted that the third duration may be the same as or different from the first duration mentioned above.

[0339] Therefore, it can be seen that the second network-side device can send the second information in the time unit at which it receives the first information. It should be noted that when WUS is effective for multiple cells (possibly including Cell A and NES Cell) at the same time, multiple cells can receive WUS in a beam sweeping manner. The time when different cells receive WUS may be different, so the time when different cells send WUS Response (i.e., WUS feedback) may also be different.

[0340] The second network side device may also send the second information at the next time unit after the moment when it receives the first information;

[0341] The second network side device may also send the second information in a time unit located after the third time period of receiving the first information;

[0342] The second network side device may also send the second information in the next time unit after the third time period of receiving the first information;

[0343] The second network side device may also send the second information in the time unit where the downlink control channel corresponding to the SSB associated with the first information is located.

[0344] The downlink control channel may include a Type 0 PDCCH corresponding to the SSB index.

[0345] Item E-2: K2 consecutive time units starting from the second time unit;

[0346] Therefore, it can be seen that the second network side device can send the second information for K2 consecutive time units starting from the time unit at which it receives the first information;

[0347] The second network side device may also send the second information for K2 consecutive time units starting from the next time unit after the moment when it receives the first information;

[0348] The second network side device may also send the second information in a continuous K2 time units starting from the time unit at which the moment when the second network side device receives the first information after the third time length has elapsed;

[0349] The second network side device may also send the second information in a continuous K2 time units starting from the next time unit after the moment when the third time length of receiving the first information has passed;

[0350] The second network side device may also send the second information in K2 consecutive time units starting from the time unit where the downlink control channel corresponding to the SSB associated with the first information is located.

[0351] It is understandable that the values ​​of K2 in the various cases described herein may be the same or different. K2 may be predefined by the protocol or configured on the network side.

[0352] Item E-3: Time after the third timer expires; for example, the second network-side device starts the third timer after receiving the WUS, and sends a WUS Response (i.e., WUS feedback) after the third timer expires. The starting point or duration of the third timer may be agreed upon in the protocol or configured on the network side.

[0353] Item E-4: The time period corresponding to the fourth timer; for example, the second network-side device sends a WUS Response (i.e., WUS feedback) within the time period corresponding to the fourth timer after receiving the WUS. The starting point or duration of the fourth timer may be agreed upon by the protocol or configured on the network side.

[0354] Item E-5: The time period corresponding to the second predetermined window; for example, the second network-side device sends a WUS Response (i.e., WUS feedback) within the first predetermined window after receiving the WUS. The starting point or duration of the second predetermined window may be agreed upon in the protocol or configured on the network side.

[0355] Item E-6: a specific position within the second specific time unit; for example, the second network-side device sends a WUS Response (ie, WUS feedback) in the first M symbols of a slot, or the last M symbols of a slot.

[0356] Optionally, the second information (i.e., at least one of the specific information and target information) is carried in at least one of the following Q-1 to Q-13:

[0357] Q-1: SSB;

[0358] Q-2: SIB1;

[0359] Q-3: Type 0 physical downlink control channel (Type 0 PDCCH);

[0360] Q-4: Random access response physical downlink control channel (Msg2 PDCCH);

[0361] Q-5: Random access response physical downlink shared channel (Msg2 PDSCH);

[0362] Q-6: Paging Physical Downlink Control Channel (Paging PDCCH);

[0363] Q-7: Paging Physical Downlink Shared Channel (Paging PDSCH);

[0364] Q-8: Contention Resolution Message Physical Downlink Control Channel (Msg4 PDCCH);

[0365] Q-9: Contention Resolution Message Physical Downlink Shared Channel (Mg4 PDSCH);

[0366] Q-10: Message B Physical Downlink Control Channel (MsgB PDCCH);

[0367] Item Q-11: Message B Physical Downlink Shared Channel (MsgB PDSCH);

[0368] Item Q-12: A signal dedicated to transmitting the second information;

[0369] Q-13: A channel dedicated to transmitting the second information.

[0370] Among them, carrying the second information in the existing channel (ie, items Q-1 to Q-11 above) can reuse some existing bits or resources to avoid new overhead; however, the flexibility is worse and the information that can be carried is limited.

[0371] Carrying the second information in a dedicated channel (i.e., items Q-12 to Q-13 above) is more flexible and can carry more information, but it requires designing a new channel and introduces additional overhead.

[0372] It should be noted that Type 0 PDCCH refers to the PDCCH transmitted on CORESET # 0; in addition, for the above-mentioned Type 0 PDCCH, the position of the monitoring opportunity (MO) is determined relative to the WUS; optionally, some fields are set to invalid (Invalid), for example, the frequency domain resource allocation (FDRA) can be Invalid to indicate that this is a WUS Response (ie, WUS feedback).

[0373] Optionally, the network-side device (i.e., the second network-side device) that sends the second information (i.e., at least one of the above-mentioned specific information and target information) satisfies at least one of the following F-1 to F-6:

[0374] Item F-1: The signal strength between the terminal and the terminal is greater than or equal to a first threshold, and the terminal is the terminal that sends the first information;

[0375] Item F-2: The signal strength between the terminal and the mobile station is less than or equal to a second threshold; the signal strength may include at least one of Reference Signal Received Power (RSRP), Reference Signal Received Quality (RSRQ), Signal to Interference plus Noise Ratio (SINR), and Received Signal Strength Indicator (RSSI);

[0376] F-3: The interference intensity is greater than or equal to the third threshold;

[0377] F-4: interference intensity is less than or equal to the fourth threshold;

[0378] Item F-5: In a specific energy-saving state;

[0379] Item F-6: Not in a specific energy-saving state.

[0380] Among them, in items F-5 and F-6, the specific energy-saving state may include an energy-saving state in which SIB1 is not sent, or an energy-saving state in which any downlink signal is not sent.

[0381] Optionally, the network-side device that sends the second information (i.e., at least one of the above-mentioned specific information and target information) includes at least one of the following K-1 to K-2:

[0382] Item K-1: a network-side device that meets a first condition, the first condition including at least one of being in a non-energy-saving state, periodically sending a first system information block SIB1, and a terminal currently resident, the terminal being the terminal that sends the first information;

[0383] Item K-2: at least one network-side device that meets the second condition, where the second condition includes at least one of being in an energy-saving state, not sending SIB1 periodically, not sending SIB1, and the terminal needs to be activated.

[0384] The network side device that meets the first condition sends the second information, which can be understood as CellA sending the second information as mentioned above; the network side device that meets the second condition sends the second information, which can be the NES Cell sending the second information as mentioned above.

[0385] It should be noted that when the terminal sends the first information, it can directly send the first information to the network-side device that meets the second condition, or it can send the first information to the network-side device that meets the first condition, so that the network-side device that meets the first condition notifies the network-side device in the energy-saving state to switch to the non-energy-saving state and / or send the target information. Therefore, if the network-side device that receives the first information needs to send the second information, it can also send it directly to the terminal, or first send it to the network-side device that meets the first condition, so that the network-side device that meets the first condition can send the second information to the terminal based on the received second information.

[0386] Therefore, the network-side device in item K-1 herein may refer to the network-side device that sends the second information to the terminal; the network-side device in item K-2 may refer to the network-side device that sends the second information to the network-side device or terminal that meets the first condition. It is understood that in item K-2, the network-side device that sends the second information to the network-side device or terminal that meets the first condition may include all network-side devices that receive the first information and meet the second condition, or may include some of the network-side devices.

[0387] Optionally, the network-side device that sends the second information (i.e., the second network-side device) is determined by at least one of the following methods J-1 to J-4:

[0388] Item J-1: Multiple third network-side devices interact or negotiate to determine; wherein the third network-side devices that interact or negotiate may include at least one of a network-side device that meets the first condition and a network-side device that meets the second condition;

[0389] As can be seen from item J-1, multiple third-party network devices that receive the first information can interact or negotiate to determine which of these third-party network devices should send the second information. It is understood that the network device that is determined through interaction or negotiation to send the second information can send the second information directly to the terminal or transparently transmit it to the terminal via a network device that meets the first condition.

[0390] For example, at least one NES cell interacts or negotiates with each other about who sends the second information, so that the NES cell indicated by the interaction or negotiation result sends the second information to CellA, which then transparently transmits the second information to the terminal.

[0391] Alternatively, for example, at least one NES Cell interacts or negotiates with each other to determine who sends the second information, so that the NES Cell indicated by the interaction or negotiation result sends the second information to the terminal.

[0392] Item J-2: Designation by a network-side device that meets a first condition, where the first condition includes at least one of being in a non-energy-saving state, periodically transmitting SIB1, and the terminal being currently resident, and the terminal is the terminal that sends the first information; wherein the network-side device that meets the first condition may designate the network-side device that is to send the second information to the terminal based on second information received from multiple network-side devices that meet a second condition and receive the first information;

[0393] For example, after receiving the first information, at least one NES cell may send the second information to CellA, so that CellA specifies which NES cell or cells are to send the second information to the terminal.

[0394] Item J-3: Determined according to predefined rules;

[0395] Item J-4: Specific network-side device designation; it can be understood that the specific network-side device may be a network-side device that meets the first condition.

[0396] Optionally, the multiple third network-side devices determine the network-side device that sends the second information by exchanging third information;

[0397] The third information includes at least one of the following items V-1 to V-5:

[0398] Item V-1: the content of the first information;

[0399] V-2: Signal strength measured by the third network-side device; that is, the signal strength between the terminal and each third network-side device, such as RSRP, RSRQ, SINR, RSSI, etc.

[0400] V-3: interference intensity measured by the third network-side device;

[0401] Item V-4: energy-saving status of the third network-side device; for example, the current energy-saving status of the third network-side device;

[0402] Item V-5: the second information of the third network side device.

[0403] Optionally, the manner in which the multiple third network-side devices interact with the third information includes one of the following manners 1 to 3:

[0404] Method 1: Each third network-side device sends the third information independently;

[0405] Method 2: The third information of each third network-side device is encapsulated into a signaling and then sent;

[0406] Method 3: According to the target ranking of each third-party network device, each third-party network device transmits its own third information and the received third information to the next third-party network device in the target ranking, and the third-party network device at the end of the target ranking transmits its own third information and the received third information to the processing node; that is, each third-party network device encapsulates the information layer by layer from far to near according to the target ranking and transmits it to the processing node. For example, if the third-party network devices include the first to fourth base stations, and the ranking of these four base stations is first base station, second base station, third base station, and fourth base station, the first base station transmits its own third information to the second base station, the second base station transmits the first base station's third information and its own third information to the third base station, the third base station transmits the first base station's third information, the second base station's third information, and its own third information to the fourth base station, and finally, the fourth base station transmits the third information of the first to fourth base stations to the processing node.

[0407] Among the plurality of third network-side devices, there is a processing node, that is, the processing node is used to determine the network-side device to which the second information needs to be sent based on the third information of each third network-side device;

[0408] In this way, based on the first approach, the non-processing nodes can independently send their respective third information to the processing nodes, wherein the non-processing nodes include the network-side devices other than the processing nodes in the plurality of third network-side devices;

[0409] Based on the second approach, a node for information packaging and encapsulation may exist among the non-processing nodes, for example, a packaging node. Then, other network-side devices in the non-processing nodes, except for the packaging node, may each send their respective third information to the packaging node. The packaging node then packages its own third information and the received third information into a single signaling message, which is then sent to the processing node. The packaging node may be a node located in a central geographical location among the non-processing nodes.

[0410] Based on the third method, each non-processing node is sorted based on certain rules to obtain a target sorting, so that in the order of the target sorting, each non-processing node sends its own third information and the third information received from the previous non-processing node to the next non-processing node, until the last non-processing node sends the third information of all non-processing nodes to the processing node.

[0411] Optionally, the processing node includes at least one of the following:

[0412] A network-side device that meets the first condition;

[0413] The specific network side device is determined from the network side devices that meet the second condition, where the second condition includes at least one of being in an energy-saving state, not sending SIB1 periodically, not sending SIB1, and the terminal needs to be activated.

[0414] It can be understood that the specific network side device can be pre-specified or determined based on the geographical location of the network side device that receives the first information and meets the second condition. For example, the specific network side device can be a network side device located at the center of the geographical locations of all network side devices that receive the first information and meet the second condition.

[0415] Optionally, the target ranking is determined according to at least one of the following P-1 to P-5:

[0416] P-1: distance between each third network-side device and the processing node;

[0417] P-2: signal strength between each third network-side device and the processing node;

[0418] P-3 item: cell index size of each third network side device;

[0419] Item P-4: distance between each third network-side device and the terminal, the terminal being the terminal sending the first information;

[0420] Item P-5: signal strength between each third network-side device and the terminal.

[0421] It should be noted that when sorting multiple third-network-side devices based on at least two of the above P-1 to P-5, the priority of each content can be determined in advance, and sorting can be performed based on the content with the highest priority first. Then, different third-network-side devices with the same highest-priority content can be sorted based on the content with the next priority.

[0422] Optionally, the third information is interacted through an Xn interface, where Xn represents an interface between network-side devices.

[0423] It should be noted that the interaction of the third information between different systems (inter-RAT) can be completed through the core network.

[0424] Optionally, the second network side device sending the second information according to the first information includes at least one of the following:

[0425] The second network side device sends the second information only once according to the first information;

[0426] The second network side device repeatedly transmits the second information according to the first information;

[0427] The second network side device retransmits the second information according to the first information.

[0428] It can be seen from this that the second information can be sent only once, or can be repeatedly transmitted, or can be retransmitted.

[0429] Optionally, the second information (i.e., at least one of the specific information and target information) includes at least one of the following items B-1 to B-13:

[0430] Item B-1: a cell identifier or a list of cell identifiers of the network-side device that sends the second information;

[0431] Item B-2: the cell identifier or cell identifier list of the network-side device that sends the target information;

[0432] Item B-3: a cell identifier or a list of cell identifiers of a network-side device that successfully receives the first information;

[0433] Item B-4: an indication of whether the first information is successfully received;

[0434] Item B-5: Instruction on whether to continue monitoring the target information;

[0435] Item B-6: the time-frequency domain resource location of the target information;

[0436] Item B-7: time-frequency domain resource location of the physical downlink control channel PDCCH for scheduling the target information;

[0437] Item B-8: The period of the target information;

[0438] Item B-9: a period of the PDCCH for scheduling the target information;

[0439] Item B-10: Number of transmissions of the target information;

[0440] Item B-11: the number of transmissions of the PDCCH scheduling the target information;

[0441] Item B-12: Scheduling information related to the transmission of the target information;

[0442] Item B-13: Scheduling information related to the PDCCH that schedules the target information.

[0443] It is understood that the relevant explanations of items B-1 to B-13 here can be found in the above text and will not be repeated here.

[0444] Optionally, the information type of the second information includes at least one of the following:

[0445] Physical layer messages, physical layer signals, and higher layer messages;

[0446] The physical layer message (or physical layer signal) includes at least one of the following:

[0447] Sequence, physical layer excitation signal, downlink control information DCI, PDCCH;

[0448] The high-level message includes at least one of the following:

[0449] Radio Resource Control (RRC) message, Media Access Control Element (MAC CE), Media Access Control Protocol Data Unit (MAC PDU), and Random Access Response (RAR).

[0450] It should be noted that when the information type of the second information is a sequence, different sequences may represent different meanings (i.e., representing different contents in the second information, such as whether the first information is successfully received), for example, different meanings may be represented by indexes of different sequences, or, for example, different cyclic shift values ​​may be used to represent different meanings;

[0451] Alternatively, when the information type of the second information is a physical layer excitation signal, different meanings can be expressed by the intensity of the physical layer excitation signal, for example, by detecting the relevant energy intensity. When the intensity exceeds a predefined threshold, it indicates that the first information is received successfully, otherwise the reception fails.

[0452] Alternatively, different meanings can be expressed through DCI;

[0453] Alternatively, different meanings may be expressed through PDCCH.

[0454] When the information type of the second information is a high-layer message, the second information can be transmitted through at least one of RRC, MAC CE, MAC PDU, and RAR.

[0455] For example, the second information may be transmitted using a modified RAR MAC PDU. Specific implementations may include at least one of the following:

[0456] This is achieved by modifying the definition of relevant fields in the existing RAR MAC PDU (for example, using the uplink grant (UL Grant) related fields in the RAR MAC PDU to carry the second information);

[0457] A subPDU is added after the last subPDU of the RAR MAC PDU to carry the second information.

[0458] It should be noted that the above-mentioned RAR MAC PDU can be called MAC PDU (RAR).

[0459] Alternatively, a new MAC PDU or MAC CE may be introduced to transmit the second information; for example, a new logical channel identifier (LCID) or extended logical channel identifier (eLCID) may be introduced to specifically indicate that the associated MAC PDU or MAC CE is used to transmit the second information;

[0460] Alternatively, a new RRC parameter may be introduced to transmit the second information.

[0461] Optionally, when the information type of the second information includes at least one of DCI and PDCCH, the second information is scrambled by a specific radio network temporary identity (Radio Network Temporary Identity, RNTI).

[0462] That is, if the second information is downlink control information (DCI) or a PDCCH, a specific RNTI, such as WUS-RNTI, may be used for scrambling. For example, if a terminal uses a specific RNTI (such as WUS-RNTI) to descramble the received DCI, a terminal that does not know the specific RNTI cannot decrypt the second information.

[0463] In summary, taking the first information as WUS and the specific information as WUS Response as an example, the following implementation modes 1 to 3 of the information transmission method according to the embodiment of the present application are introduced.

[0464] Implementation method 1: Common WUS, with WUS Response; as shown in FIG11 , includes the following steps 1101 to 1105:

[0465] Step 1101: The UE obtains second configuration information from Cell A. The second configuration information includes a Cell ID list and WUS configuration (transmission resources and number of repeated transmissions).

[0466] Step 1102: The UE repeatedly transmits the WUS N times according to the second configuration information;

[0467] Among them, at least one cell (which may include Cell A or multiple other NES cells) beam sweeps to receive WUS;

[0468] Step 1103: The multiple cells that receive the WUS signal determine the cell X that will ultimately send the WUS Response through inter-cell interaction / negotiation. Cell X sends the WUS Response information to the UE in the beam direction in which it receives the WUS signal.

[0469] Step 1104: The UE monitors the WUS Response on the Type 0 PDCCH corresponding to all SSBs associated with the WUS. The WUS Response includes the scheduling information of the on-demand SIB1 of the NES cell that sends the WUS Response and the corresponding Cell ID and other information.

[0470] Step 1105: The UE receives SIB1 based on the scheduling information in the WUS Response, that is, the UE receives SIB1 from the NES cell according to the scheduling information of the on-demand SIB1 in the WUS Response.

[0471] Implementation method 2: Common WUS, with WUS Response; as shown in FIG12 , includes the following steps 1201 to 1206 :

[0472] Step 1201: The UE obtains second configuration information from Cell A. The second configuration information includes a Cell ID list, WUS configuration (transmission resources, number of repeated transmissions), and WUS Response sending configuration.

[0473] Step 1202: The UE repeatedly transmits the WUS N times according to the second configuration information;

[0474] Among them, at least one cell (which may include Cell A or multiple other NES cells) beam sweeps to receive WUS;

[0475] Step 1203: The NES cells send their respective WUS Responses to Cell A. That is, the multiple cells that receive the WUS signal send the WUS Responses to Cell A through the inter-cell interface.

[0476] Step 1204: Cell A decides which NES Cell's WUS Response to send to the UE;

[0477] Step 1205: The UE receives the WUS Response on the time-frequency domain resources specified in the WUS Response sending configuration. The WUS Response includes the scheduling information of the on-demand SIB1 of the corresponding NES cell and the Cell ID.

[0478] Step 1206: The UE receives SIB1 based on the scheduling information in the WUS Response, that is, the UE receives SIB1 from the NES cell according to the scheduling information of the on-demand SIB1 in the WUS Response.

[0479] Implementation method 3: Dedicated WUS, with WUS Response; as shown in FIG13 , includes the following steps 1301 to 1306 :

[0480] Step 1301: The UE obtains second configuration information from Cell A or the target NES Cell. The second configuration information includes Cell ID (i.e., the cell ID of the target NES Cell), WUS transmission resources, and WUS Response sending configuration.

[0481] Step 1302: The UE sends a WUS according to the second configuration information, that is, the UE transmits the WUS on the WUS transmission resources indicated in the second configuration information;

[0482] Step 1303: The target NES Cell monitors the WUS, that is, monitors the WUS at the WUS transmission resource location indicated in the second configuration information;

[0483] Step 1304: After receiving the WUS, the target NES Cell sends a WUS Response to the UE on the resource indicated by the WUS Response sending configuration;

[0484] Step 1305: The UE receives a WUS Response according to the WUS Response sending configuration. The WUS Response includes at least the scheduling information of the on-demand SIB1.

[0485] Step 1306: The UE receives SIB1 from the target NES cell according to the scheduling information of the on-demand SIB1.

[0486] From the above, it can be seen that in the embodiment of the present application, the transmission method of the UL WUS response is considered during the process of UL WUS triggering the sending of on-demand SIB1; by sending the WUS Response, the terminal can be informed in advance of the time point to start blind detection or receive SIB1, thereby reducing the terminal blind detection time and improving the terminal power saving effect.
