The following description describes the New Radio (NR) system for example purposes, and the NR term is used in most of the following descriptions, but these technologies can also be applied to systems other than the NR system, such as the 6th th Generation (6G) communication system.

[0059] Figure 1The block diagram of a wireless communication system to which embodiments of the present application can be applied is shown. The wireless communication system includes a terminal 11 and a network-side device 12. Among them, the terminal 11 can be a mobile phone, a tablet personal computer, a laptop computer, a notebook computer, a personal digital assistant (PDA), a handheld computer, a netbook, an ultra-mobile personal computer (UMPC), a mobile internet device (MID), an augmented reality (AR), a virtual reality (VR) device, a robot, a wearable device, a flight vehicle, a vehicle user equipment (VUE), a shipborne device, a pedestrian user equipment (PUE), a smart home (home devices with wireless communication functions, such as refrigerators, TVs, washing machines or furniture, etc.), a game console, a personal computer (PC), a teller machine or a self-service machine, etc. Wearable devices include: smart watches, smart bracelets, smart earphones, smart glasses, smart jewelry (smart bracelets, smart bracelets, smart rings, smart necklaces, smart anklets, smart ankle chains, etc.), smart wristbands, smart clothing, etc. Among them, the vehicle user equipment can also be referred to as a vehicle terminal, a vehicle controller, a vehicle module, a vehicle component, a vehicle chip or a vehicle unit, etc. It should be noted that the specific type of the terminal 11 is not limited in the embodiments of the present application. The network-side device 12 can include an access network device or a core network device. Among them, the access network device can also be referred to as a radio access network (RAN) device, a radio access network function or a radio access network unit. The access network device can include a base station, a wireless local area network (WLAN) access point (AP) or a wireless fidelity (WiFi) node, etc.Among them, the base station can be referred to as Node B (NB), Evolved Node B (eNB), the next generation Node B (gNB), New Radio Node B (NR Node B), access point, Relay Base Station (RBS), Serving Base Station (SBS), Base Transceiver Station (BTS), radio base station, radio transceiver, Basic Service Set (BSS), Extended Service Set (ESS), home Node B (HNB), home evolved Node B, Transmission Reception Point (TRP), or some other suitable term in the art. As long as the same technical effect is achieved, the base station is not limited to specific technical terms. It should be noted that in the embodiments of this application, only the base station in the NR system is taken as an example for introduction, and the specific type of the base station is not limited.

[0060] The core network device may include, but is not limited to, at least one of the following: core network nodes, core network functions, Mobility Management Entity (MME), Access and Mobility Management Function (AMF), Session Management Function (SMF), User Plane Function (UPF), Policy Control Function (PCF), Policy and Charging Rules Function (PCRF), Edge Application Server Discovery Function (EASDF), Unified Data Management (UDM), Unified Data Repository (UDR), Home Subscriber Server (HSS), Centralized network configuration (CNC), Network Repository Function (NRF), Network Exposure Function (NEF), Local NEF (L-NEF), Binding Support Function (BSF), Application Function (AF), etc. It should be noted that in the embodiments of this application, only the core network devices in the NR system are taken as examples for introduction, and the specific types of core network devices are not limited.

[0061] Figure 2 Fig. shows a gNB system architecture diagram applicable to this embodiment, such as Figure 2As shown in the figure, the NR access network splits the gNB into a central unit gNB-CU and a distributed unit gNB-DU, and connects the central unit and the distributed unit through the F1 interface. Among them, each gNB only contains one central unit CU, contains one or more distributed units DU, and one distributed unit DU contains one or more cells. The CU contains the protocol stack above the Packet Data Convergence Protocol (PDCP), and the DU contains the protocol stack below the PDCP (Packet Data Convergence Protocol) layer: Radio Link Control (RLC), Medium Access Control (MAC), and Physical layer (PHY); in the control plane, the central unit CU contains Radio Resource Control (RRC) and the PDCP in the control plane (PDCP-C); in the user plane, the central unit CU contains Service Data Adaptation Protocol (SDAP) and the PDCP in the user plane (PDCP-U).

[0062] In the related art, the user equipment UE first detects the Primary Synchronization Signal (PSS) to obtain a part of the physical cell ID, that is obtain the Orthogonal Frequency Division Multiplexing (OFDM) symbol timing and frequency synchronization; then detect the Secondary Synchronization Signal (SSS) to obtain another part of the physical cell ID, that is obtain the complete physical cell ID, that is that is Then, the user equipment detects the Physical Broadcast Channel PBCH and the Demodulation Reference Signal DMRS for the PBCH to obtain the System Frame Number and the SSB index, and further obtain the subframe timing.

[0063] In NR, the SSB period is configured in the first System Information Block (SIB1), and it can be 5 ms, 10 ms, 20 ms, 40 ms, 80 ms, or 160 ms. When initially accessing the network, if the UE has not received SIB1, it will search for SSBs according to the default 20-ms period. SSBs do not appear at regular intervals but rather appear several times within a specific half-frame at regular intervals. This is designed for beam scanning. Each of these SSBs corresponds to a beam scanning direction, and ultimately there will be an SSB for each direction. These several SSBs are called an SSB set, and all SSBs in an SSB set must be within the same half-frame.

[0064] In related technologies, multi-carrier is a typical operation in 5G NR networks to enhance network-side capacity. For a Pcell or a PScell, the base station must send periodic SSBs, and the SSB period needs to be less than or equal to 20 ms for successful initial search by user equipment. For an intra-band Scell, the base station can send SSBs, and in this case, the SSB-related parameters are configured when adding this Scell; or it can not send SSBs, and in this case, the SSB-related parameters are not configured when adding this Scell, and the terminal obtains timing through the SSBs on the Pcell. For an inter-band Scell, the base station must send SSBs, and the SSB-related parameters are configured when adding this Scell.

[0065] Most of the power consumption in the NR network comes from the base station, and 90% of the power consumption of the NR base station comes from the Active Antenna Unit (AAU). Due to higher frequency bands, wider bandwidths, more TRXs, etc., the power consumption of a single NR base station is currently 3 to 4 times higher than that of LTE. In addition, in terms of Operational Expenditure (OPEX), the electricity cost of the base station accounts for nearly 20% of the entire network operation cost. For some operators, the electricity cost is more than half of the total profit. Therefore, network energy saving in NR becomes even more critical for the great success of 5G. According to the actual load situation, the base station can implement different levels of energy-saving measures, such as shutting down the base station, shutting down carriers / cells, shutting down channels, shutting down SSBs / beams, shutting down antennas / panels, cell Discontinuous Transmission (cell DTX) and / or Discontinuous Reception (cell DRX), Channel State Information (CSI) adaptation, etc.

[0066] In the related art, SSBs are continuously transmitted according to a fixed period. In the case where there are fewer user equipments accessing the cell, it is not conducive to energy saving of the network side equipment, especially the energy saving of the base station as the second cell, to require the base station to continuously transmit SSBs according to a fixed period. Although some conditions are defined such that an SSB-less cell can refrain from transmitting SSBs, there are still Scells that do not meet the conditions and need to periodically transmit SSBs. To achieve further network energy saving, it is necessary to consider an SSB transmission mechanism based on the actual needs of UEs on these cells.

[0067] An embodiment of the present application provides an information transmission method, which can achieve on-demand transmission of reference signals (such as SSBs) and achieve the purpose of energy saving of network side equipment.

[0068] The following will, with reference to the accompanying drawings, elaborate on an information transmission method provided by an embodiment of the present application through some embodiments and their application scenarios.

[0069] In a first aspect of an embodiment of the present application, an information transmission method is provided. Referring to Figure 3 , Figure 3 which shows a flowchart of the steps of an information transmission method, as Figure 3 shown, the information transmission method may include:

[0070] The network side equipment performs at least one of the following:

[0071] Step S301: Transmit a first reference signal in a first transmission mode;

[0072] Step S302: Transmit a first reference signal according to the auxiliary information reported by a user equipment (UE);

[0073] Step S303: Transmit first indication information related to the first reference signal, where the first indication information includes at least one of the following:

[0074] A transmission indication of the first reference signal;

[0075] A pause transmission indication of the first reference signal;

[0076] The first transmission mode.

[0077] It should be noted that the network side equipment that transmits the reference signal, the network side equipment that transmits the indication information, and the network side equipment that receives the UE auxiliary information may be the same network side equipment or may not be the same network side equipment.

[0078] In a possible scenario, when the network-side device is a secondary cell (Scell) in the inactive state, if the Scell in the inactive state needs to trigger the transmission of the first reference signal, it is necessary to inform the UE through other cells (for example, cells in the active state). Otherwise, the UE will not receive the first reference signal on the Scell in the inactive state. Optionally, the Scell in the inactive state needs to first send the relevant information of the first reference signal to other cells, and then other cells forward or notify the UE. Then the UE sends feedback information to other cells, and then other cells notify the Scell in the inactive state, or directly send the UE's feedback information to the Scell in the inactive state, so as to help the Scell in the inactive state determine whether to send the first reference signal and the transmission time of the first reference signal.

[0079] Among them, the relevant information of the first reference signal includes at least one of the following:

[0080] Trigger the transmission of the first reference signal;

[0081] Indicate the range of the first reference signal transmission;

[0082] The destination terminal of the first reference signal transmission;

[0083] The transmission time of the first reference signal.

[0084] Among them, other cells include at least one of the following:

[0085] The primary cell (Pcell) of the destination terminal;

[0086] Cells in the active state;

[0087] Active Scell.

[0088] Among them, cells in the active state include at least one of the primary cell (Pcell) in the active state and the secondary cell (Pcell) in the active state. The information interaction between the Scell in the inactive state and other cells is carried out through at least one of the following: Xn interface; NG interface; F1 interface; wireless backhaul technology.

[0089] Optionally, the first reference signal represents a reference signal for transmission between a user equipment (UE) and a network-side device, and is used for synchronization, measurement, demodulation, channel state measurement, phase tracking, etc. For example, SSB, Demodulation Reference Signal (DMRS), Channel State Information Reference Signal (CSI-RS), SSB, Tracking Reference Signal (TRS), Phase Tracking Reference Signal (PTRS), etc. The user equipment refers to a terminal device, such as Figure 1 the terminal in Figure 1 . In the embodiments of the present application, the UE may be

[0090] the terminal device 11 in. For the examples of the terminal device 11, reference may be made to the foregoing. It may be a UE accessing a Primary Cell (Pcell), or a UE accessing a Secondary Cell (Scell). In this embodiment, it is not limited thereto. In some embodiments, the first reference signal is SSB; in other embodiments, the first reference signal includes at least one of SSB, Demodulation Reference Signal (DMRS), Channel State Information Reference Signal (CSI-RS), Phase Reference Signal (TRS), and Phase Tracking Reference Signal (PTRS).

[0091] It should be noted that the network-side device may include a network-side device on a satellite, such as a base station on a satellite, or may include a network-side device on the ground, such as a ground base station. In this embodiment, the network-side device may execute step S301, that is, the network-side device itself sends the first reference signal to the UE according to the set first transmission mode, so that the UE uses the received first reference signal for synchronization. The first transmission mode is different from a fixed transmission period. For example, the reference signal is sent in a transmission mode with a gradually increasing time interval, so as to reduce unnecessary reference signal transmission and achieve the purpose of energy saving of the network-side device.

[0092] In this embodiment, the network-side device may further perform step S303. The network-side device may send first indication information related to the first reference signal to control the transmission of the first reference signal, pause the transmission, and update the transmission mode of the first reference signal according to the first indication information, so as to flexibly control the transmission of the reference signal. In an alternative embodiment, in step S303, the sending of the first indication information related to the first reference signal includes:

[0093] Sending the first indication information related to the first reference signal according to the auxiliary information reported by the UE.

[0094] In this embodiment, the network-side device may send indication information after receiving the auxiliary information reported by the UE, and then perform the transmission, pause the transmission, and update the transmission mode of the first reference signal according to the indication information, so as to achieve flexible transmission of the first reference signal according to the actual needs of the UE, and achieve the purpose of energy saving for the network-side device.

[0095] Optionally, the first indication information may be explicitly or implicitly indicated by at least one of Downlink Control Information (DCI), Medium Access Control Control Element (MAC CE), RRC, and cell switch indication.

[0096] Exemplarily, the DCI may be an existing DCI, such as a single-cell uplink scheduling DCI such as DCI 0_0 / 0_1 / 0_2 or a single-cell downlink scheduling DCI such as DCI 1_0 / 1_1 / 1_2, or may be a multi-cell scheduling DCI such as DCI 0_3 or 1_3. It may be a scheduling DCI or a non-scheduling DCI, and may also be a new group common DCI or reuse an existing group common DCI, such as DCI 2-9.

[0097] Exemplarily, the MAC CE may be an existing MAC CE, such as a Scell activation or Scell deactivation MAC CE, or a MAC CE other than a Scell activation or Scell deactivation MAC CE, such as a new MAC CE.

[0098] There is no sequence among the above steps S301 - S303, and they can be set according to actual needs.

[0099] In specific implementation, for the above steps S301 and S303, there are multiple situations for the first transmission mode, and different first transmission modes will cause certain differences in the information transmission method proposed in the embodiments of the present application. In an alternative embodiment, the first transmission mode includes at least one of the following:

[0100] The first transmission period of the first reference signal, where the first transmission period is greater than 160 milliseconds;

[0101] At least two different transmission periods of the first reference signal;

[0102] The number of transmission periods of the first reference signal;

[0103] The transmission method of the first reference signal, where the transmission method is used to indicate the time domain interval or the number of transmissions within the time slot used for transmitting the first reference signal;

[0104] The transmission mode information of the first reference signal, where the transmission mode information is used to characterize at least one of the following: a transmission mode with a gradually increasing time interval, a transmission mode with an unchanged transmission period;

[0105] The transmission time information of the first reference signal, including at least one of the following: the transmission time window of the first reference signal, the transmission duration, the starting transmission resource position, the ending transmission resource position.

[0106] Among them, the transmission period represents the time interval at which the network-side device transmits the first reference signal at fixed time intervals. At least two different transmission periods indicate that the transmission period is adjustable and can be adjusted from one transmission period (for example, the fixed period used for continuous transmission in the related art, or another period different from this fixed period) to another transmission period. The number of transmission periods represents the number of periods in which the network-side device transmits the first reference signal according to the transmission period. Exemplarily, if the transmission period is 10 ms and the number of transmission periods is 5 times, then the network-side device transmits the first reference signal once every 10 ms (one or more first reference signals can be transmitted each time), and stops transmitting the first reference signal after a total of 5 periods. The transmission method is used to indicate the time domain interval or the number of transmissions within the slot (i.e., time slot) used for transmitting the first reference signal. For example, whether the first reference signal will specifically transmit 2 or 3 within one slot, and whether the interval between each two is 2 symbols or there is no interval, etc. The transmission time window represents transmitting the first reference signal within the specified time window.

[0107] The following implementation manners further illustrate the information transmission methods involved in steps S301 and S303 based on different first transmission modes in the above embodiments.

[0108] Embodiment 1-1

[0109] This embodiment describes the case where the network-side device executes step S301, and the network-side device sends the first reference signal according to a set fixed transmission period. Exemplarily, the network-side device sends the first reference signal once every 320 ms (transmission period).

[0110] In the first transmission mode: the transmission period of the first reference signal is a set fixed value (such that this value as the period length can meet the synchronization / measurement requirements of all UEs), and the transmission mode information of the first reference signal is a transmission mode with an unchanged transmission period.

[0111] It can be understood that the maximum transmission period of the current SSB is 160 ms. If a larger transmission period is adopted, further energy conservation can be achieved. If a user equipment determines that it cannot meet its own synchronization or measurement requirements under such a transmission period, it triggers the base station to send an additional SSB.

[0112] Embodiment 1-2

[0113] This embodiment describes the case where the network-side device first executes step S303 and then executes step S301 (that is, the network-side device first sends the transmission indication of the first reference signal and then sends the first reference signal). The network-side device first sends the first indication information, and then sends the first reference signal according to the transmission indication or the first transmission mode of the first reference signal in the first indication information with a fixed transmission period. In the first transmission mode: the transmission period of the first reference signal is a set fixed value (such that this value as the period length can meet the synchronization / measurement requirements of all UEs), and the transmission mode information of the first reference signal is a transmission mode with an unchanged transmission period.

[0114] Embodiment 2-1

[0115] This embodiment describes the case where the network-side device executes step S301, and the network-side device sends the first reference signal according to a fixed transmission period. After reaching the set number of transmission periods, the transmission is paused until after waiting for the first time, and then the first reference signal is sent again with a fixed transmission period and a fixed number of transmission periods. The transmission period and the number of transmission periods may be pre-defined by the protocol or pre-configured by the network side. Exemplarily, the network-side device sends the first reference signal once every 160 ms (transmission period), then pauses sending the first reference signal after sending a total of 5 times (number of transmission periods), and after waiting for 10 s (the first time), starts to send the first reference signal once every 160 ms again.

[0116] In the first transmission mode: The transmission period of the first reference signal is a set fixed value, the number of transmission periods of the first reference signal is a set fixed value, and the transmission mode information of the first reference signal is a transmission mode with an unchanged transmission period.

[0117] Embodiment 2-2

[0118] This embodiment describes the case where the network-side device first executes step S303 and then executes step S301 (that is, the network-side device first sends a transmission indication of the first reference signal and then sends the first reference signal). The network-side device first sends the first indication information, and then according to the transmission indication or the first transmission mode of the first reference signal in the first indication information, sends the first reference signal at a fixed transmission period. After reaching the set number of transmission periods, the transmission is paused until after waiting for the first time, and then the first reference signal is restarted to be sent at a fixed transmission period and a fixed number of transmission periods. In the first transmission mode: The transmission period of the first reference signal is a set fixed value, the number of transmission periods of the first reference signal is a set fixed value, and the transmission mode information of the first reference signal is a transmission mode with an unchanged transmission period. Embodiment 3-1

[0119] This embodiment describes the case where, when the network-side device executes step S301, the network-side device gradually extends the transmission period of the first reference signal until the length of the transmission period reaches the period threshold. The network-side device pauses the transmission of the first reference signal until it resumes sending the first reference signal according to the above-mentioned transmission mode after the first time.

[0120] In the first transmission mode: The transmission period of the first reference signal is a plurality of gradually extended transmission periods. The number of transmission periods corresponding to different-sized transmission periods can be the same or different. For example, the first reference signal P1 times is sent at a transmission period of 20 ms, then the first reference signal P2 times is sent at a transmission period of 40 ms, and then the first reference signal P3 times is sent at a transmission period of 80 ms. Or, P1, P2, and P3 can be different or the same. The transmission mode information of the first reference signal represents a transmission mode with a gradually increasing time interval.

[0121] Embodiment 3-2

[0122] This embodiment describes the case where the network - side device first executes step S303 and then executes step S301 (that is, the network - side device first sends an indication of the transmission of the first reference signal and then sends the first reference signal). The network - side device first sends the first indication information, and then gradually extends the transmission period of the first reference signal according to the transmission indication or the first transmission mode of the first reference signal in the first indication information until the length of the transmission period reaches the period threshold. The network - side device pauses the transmission of the first reference signal until it resumes transmitting the first reference signal according to the above - mentioned transmission mode after the first time. In the first transmission mode: the transmission period of the first reference signal is a plurality of gradually extended transmission periods. The number of transmission periods corresponding to different - sized transmission periods can be the same or different. The transmission - mode information of the first reference signal represents a transmission mode with a gradually increasing time interval.

[0123] Embodiment 4 - 1

[0124] This embodiment describes the case where the network - side device executes step S301. The network - side device gradually extends the transmission period of the first reference signal until the length of the transmission period reaches the period threshold. The network - side device keeps transmitting the first reference signal with the current maximum transmission period until it resumes transmitting the first reference signal according to the above - mentioned transmission mode after the first time.

[0125] In the first transmission mode: the transmission period of the first reference signal is a plurality of gradually extended transmission periods. The number of transmission periods corresponding to different - sized transmission periods can be the same or different. The transmission - mode information of the first reference signal represents a transmission mode with a gradually increasing time interval. Exemplarily, the network - side device starts to transmit the first reference signal, first transmits it 2 times with a transmission period of 20 ms. When transmitting the first reference signal for the 3rd or 4th time, the interval from the previous first reference signal becomes 40 ms, which is equivalent to switching the transmission period of the first reference signal to 40 ms and then transmitting it 2 times. Then, according to the same principle, the transmission period is switched to 80 ms until it is transmitted 2 times with the configured maximum transmission period. It keeps transmitting the first reference signal with the maximum transmission period, for example, 640 ms.

[0126] Embodiment 4 - 2

[0127] This embodiment describes the case where the network - side device first executes step S303 and then executes step S301 (that is, the network - side device first sends the first indication information, that is, the indication of the transmission of the first reference signal, and then sends the first reference signal). The network - side device first sends the first indication information, and then gradually extends the transmission period of the first reference signal according to the transmission indication or the first transmission mode of the first reference signal in the first indication information until the length of the transmission period reaches the period threshold. The network - side device maintains the transmission of the first reference signal with the current maximum transmission period until the network - side device sends the first indication information (step S303), and changes the transmission period of the first reference signal according to the first transmission mode included in the first indication information or until a UE triggers the network - side device to change the transmission period (for example, the UE reports auxiliary information to the network - side device, and the auxiliary information includes a new transmission period of the first reference signal).

[0128] In an optional embodiment, the network - side device sends the first reference signal or the first indication information in accordance with at least one of the following granularities:

[0129] Serving cell;

[0130] Serving cell group;

[0131] Synchronization signal block (SSB) frequency point;

[0132] SSB frequency point group;

[0133] Physical cell identifier (PCI);

[0134] PCI group;

[0135] Measurement target;

[0136] Measurement target group;

[0137] Beam;

[0138] Beam group.

[0139] In this embodiment, when the network-side device executes step S301 (transmit the first reference signal) or step S303 (transmit the first indication information), it can be transmitted with different granularities. Among them, the serving cell represents the cell to which the UE is currently connected. Exemplarily, if the cell to which the UE is currently connected is a secondary cell Scell, then when the network-side device transmits the first reference signal or the first indication information, it can be transmitted with the granularity of the Scell (to all user equipments connected to this Scell), or, with the granularity of the Scell group to which the UE belongs (to all user equipments connected to this Scell group). Alternatively, the network-side device can also transmit the first reference signal or the first indication information according to the frequency points configured by the SSB, or the frequency point group configured by the SSB. Or, combining the SSB frequency point and the serving cell as a kind of granularity, that is, with the SSB frequency point and PCI as the granularity, the first reference signal or the first indication information is transmitted to all user equipments in the frequency points configured by the SSB and the cells corresponding to the PCI at the same time.

[0140] In specific implementation, for the above step S302, the network-side device transmits the first reference signal according to the auxiliary information reported by the user equipment UE, that is, the UE reports the auxiliary information to trigger the network-side device to transmit the first reference signal. Due to different UE requirements and complex actual situations, there are various ways for the UE to report the auxiliary information, and different transmission modes of the first reference signal of the network-side device will all cause certain differences in the information transmission method proposed in this embodiment of the application. In an optional embodiment, the transmitting the first reference signal according to the auxiliary information reported by the user equipment UE includes at least one of the following:

[0141] During the period when the network-side device transmits the first reference signal with a first transmission period, the network-side device transmits the first reference signal according to the auxiliary information reported by the UE;

[0142] The network-side device transmits the first reference signal according to a second transmission period. After transmitting a first number of times, the network-side device pauses transmitting the first reference signal until after a first time or according to the auxiliary information reported by the UE, and then continues to transmit the first reference signal;

[0143] The network-side device gradually extends the transmission period of the first reference signal until the length of the transmission period reaches a period threshold. The network-side device pauses transmitting the first reference signal until after a certain time or according to the auxiliary information reported by the UE, and then continues to transmit the first reference signal;

[0144] The network - side device gradually extends the transmission period of the first reference signal until the length of the transmission period reaches the period threshold, and then transmits the first reference signal with the maximum transmission period until, according to the auxiliary information reported by the UE or the first indication information of the network - side device, the transmission period of the first reference signal is changed, and the first reference signal is transmitted according to the new period.

[0145] In the following embodiments, based on the above - mentioned embodiments, the information transmission method involved in step S302 is further described.

[0146] Embodiment 5

[0147] This embodiment describes the situation where the network - side device executes step S302. The network - side device does not actively transmit the first reference signal until a UE reports auxiliary information, which triggers the network - side device to transmit the first reference signal. Specifically, according to the transmission mode of the first reference signal indicated in the auxiliary information, step 401 can be executed to transmit the first reference signal, or step 403 can be executed to transmit the transmission indication (the first indication information) of the first reference signal, and then the first reference signal is transmitted.

[0148] Embodiment 6

[0149] This embodiment describes the situation where step S302 (transmitting the first reference signal according to the auxiliary information reported by the UE) is executed during the period when the network - side device transmits the first reference signal with the first transmission period.

[0150] Specifically, during the period when the network - side device transmits the first reference signal with the first transmission period, if the length of the first transmission period can meet the synchronization, measurement, etc. requirements of all UEs, the first reference signal is continuously transmitted according to the first transmission period. If some UEs cannot perform synchronization or measurement actions, etc. with the first transmission period, they report auxiliary information, thereby triggering the network - side device to transmit an additional first reference signal (that is, execute step S301 to transmit the first reference signal, or execute step 403 to transmit the transmission indication (the first indication information) of the first reference signal, and then transmit the first reference signal).

[0151] Embodiment 7

[0152] This embodiment describes that the network - side device sends the first reference signal according to the second transmission period. After the number of transmissions reaches a certain value, the network - side device pauses sending the first reference signal until a UE reports auxiliary information, which triggers the network - side device to send the first reference signal (perform step 402). According to the auxiliary information reported by the UE, the network - side device continues to send the first reference signal (resumes sending the first reference signal according to the second transmission period until the number of transmissions reaches the certain value again). Specifically, when the UE reports auxiliary information, it triggers the network - side device to send the first reference signal. Then, either step 401 is executed to send the first reference signal, or step 403 is executed to send an indication of sending the first reference signal (the first indication information), and then the first reference signal is sent.

[0153] Embodiment 8

[0154] This embodiment describes that the network - side device gradually extends the transmission period of the first reference signal until the length of the transmission period reaches a period threshold. Then the network - side device pauses sending the first reference signal until a UE reports auxiliary information, which triggers the network - side device to send the first reference signal (perform step 402). According to the auxiliary information reported by the UE, the network - side device continues to send the first reference signal (resumes sending the first reference signal with the transmission period gradually extended until the length of the transmission period reaches the period threshold). Specifically, when the UE reports auxiliary information, it triggers the network - side device to send the first reference signal. Then, either step 401 is executed to send the first reference signal, or step 403 is executed to send an indication of sending the first reference signal (the first indication information), and then the first reference signal is sent.

[0155] Embodiment 9

[0156] This embodiment describes that the network - side device gradually extends the transmission period of the first reference signal until the length of the transmission period reaches the period threshold, and then keeps sending the first reference signal with the maximum transmission period until a UE reports auxiliary information, which triggers the network - side device to send the first reference signal (perform step 402). According to the auxiliary information reported by the UE, the network - side device changes the transmission period of the first reference signal and continues to send the first reference signal according to the new transmission period. If the first reference signal has been sent with a relatively large transmission period all the time, some UEs in the cell may not be able to maintain the synchronization state, so they will report auxiliary information or request information, requesting the network - side device to change to a smaller transmission period. This smaller transmission period can be indicated by the UE, determined by the network - side device according to pre - configured information, or determined according to the information of multiple UEs. In the embodiments of this application, the UE reporting auxiliary information to the network - side device can also be described as sending request information to the network - side device.

[0157] Specifically, the UE reports auxiliary information (the auxiliary information may include the transmission period of the first reference signal desired by the UE), triggers the network-side device to send the first reference signal, performs step 401 to send the first reference signal, or performs step 403 to send the first indication information, which may include: the updated first transmission mode (the transmission period of the first reference signal) or the transmission indication of the first reference signal, and then sends the first reference signal.

[0158] In the related art, the network-side device sends reference signals to each UE at a fixed period for synchronization. However, in practical applications, the method of sending reference signals at a fixed period does not take into account the actual needs of the UE and is not conducive to network energy saving. To solve the above problems, embodiments of the present application propose that when the UE has an actual need, the UE actively reports auxiliary information to the network-side device, so that the network-side device sends the first reference signal or the first indication information (to indicate to send or suspend sending the first reference signal or update the transmission period of the first reference signal) according to the received auxiliary information, realizing the on-demand sending of reference signals and achieving the purpose of network energy saving. The following embodiments specifically describe the auxiliary information reported by the UE.

[0159] In an optional embodiment, the auxiliary information reported by the UE includes at least one of the following:

[0160] The synchronization capability of the UE;

[0161] The measurement information of the UE;

[0162] The second indication information, which is used to trigger the network-side device to send the first reference signal;

[0163] The synchronization status information of the UE;

[0164] Quasi Co-Location (QCL) information;

[0165] The transmission mode of the first reference signal desired by the UE;

[0166] The decoding information of the UE;

[0167] The energy-saving information of the UE.

[0168] Optionally, the auxiliary information reported by the UE may include the second indication information for triggering the network-side device to send the first reference signal. Exemplarily, the second indication information may be in the form of 1 bit to indicate to the network-side device to send the first reference signal. The auxiliary information reported by the UE may also include the first transmission mode desired by the UE, such as the SSB pattern, including information such as the transmission period of the first reference signal and the candidate transmission resource location.

[0169] Among them, the auxiliary information reported by the UE includes the transmission mode of the first reference signal desired by the UE. Exemplarily, in the above Embodiment 9, the network device gradually extends the transmission period of the first reference signal until the length of the transmission period reaches the period threshold, and maintains the maximum transmission period to transmit the first reference signal until a UE reports auxiliary information (the transmission mode of the first reference signal desired by the UE), triggering the network device to transmit the first reference signal (perform step 402), and according to the auxiliary information reported by the UE, change the transmission period of the first reference signal, and continue to transmit the first reference signal according to the new transmission period.

[0170] Optionally, according to the auxiliary information reported by different UEs, determine a minimum or maximum transmission period, and thus transmit the first reference signal according to this transmission period. The minimum or maximum transmission period is predefined by the protocol, preconfigured by the network device, network-configured, indicated by the network device, or determined according to the auxiliary information reported by the UE.

[0171] In an optional embodiment, the synchronization capability of the UE includes at least one of the following:

[0172] The longest transmission period or the longest transmission interval of the first reference signal supported to maintain the synchronization state;

[0173] Synchronization signal processing time;

[0174] Synchronization signal type.

[0175] In specific implementation, the UE can report its own synchronization capability as auxiliary information to the network device, so that the network device can judge whether to send the first reference signal to the UE according to the synchronization capability of the UE. Among them, the longest transmission period or the longest transmission interval means that if the UE has not received the first reference signal after exceeding this longest transmission period or the longest transmission interval, it is difficult for the UE to maintain the synchronization state. The synchronization signal processing time represents the processing time of the first reference signal by the UE. The synchronization signal type means that the UE supports whether the first reference signal is a synchronization signal type based on satellite transmission, a synchronization signal type sent by a base station, or both. In this embodiment, the network device can determine the final reference signal transmission period according to the auxiliary information reported by the UE, or whether the current transmission mode of the reference signal has exceeded the longest transmission period or the longest transmission interval of the UE. If it has not exceeded, the first reference signal is not sent or the current transmission period is not changed. If it exceeds the longest transmission period or the longest transmission interval, the first reference signal is sent or a smaller transmission period that meets the UE's requirements is selected.

[0176] In an optional embodiment, the measurement information of the UE includes at least one of the following:

[0177] Measurement object; the measurement object includes at least one of the following: DMRS, CSI-RS, SSB, TRS, PTRS;

[0178] Measurement result; the measurement result includes at least one of the following: reference signal received power (RSRP), received signal strength indication (RSSI), reference signal received quality (RSRQ), signal-to-interference-plus-noise ratio (SINR).

[0179] In specific implementation, the UE may report its own measurement object and measurement result to the network-side device as auxiliary information, so that the network-side device can determine whether to send a first reference signal or a first indication information according to the measurement result of the UE. Optionally, when any measurement result of any of the above measurement objects of the UE is less than or equal to a preset threshold (which may indicate that the current synchronization state of the UE is poor and close to out-of-synchronization, and a first reference signal is needed for synchronization), the UE reports the auxiliary information to the network-side device, thereby triggering the network-side device to send a first reference signal for synchronization; or, when any measurement result of any of the above measurement objects is greater than a preset threshold (indicating that the current synchronization state of the UE is high and a first reference signal is not needed for synchronization temporarily), the UE reports the auxiliary information to the network-side device, thereby triggering the network-side device to send a first indication information to indicate to pause the sending of the first reference signal.

[0180] In an optional embodiment, the synchronization state information of the UE includes at least one of the following:

[0181] The transmission period of the first reference signal expected by the UE;

[0182] The number of transmissions or repetition times of the first reference signal expected by the UE;

[0183] Synchronization state;

[0184] The latest time for the UE to expect to receive the first reference signal;

[0185] The offset value of the cyclic prefix (CP).

[0186] In specific implementation, the UE may report its own synchronization status information as auxiliary information to the network-side device, so that the network-side device can determine whether to send the first reference signal or the first indication information to the UE according to the synchronization status of the UE. Exemplarily, when the UE believes that the current transmission period cannot meet its own synchronization requirements, it may report the transmission period of the first reference signal expected by the UE (for example, a period smaller than the current transmission period) as auxiliary information to the network-side device, so as to request the network-side device to send the first reference signal to it according to the period expected by the UE. Optionally, the UE may report the number of transmissions or the number of repetitions of the first reference signal it expects as auxiliary information to the network-side device, so that the network-side device updates the transmission mode of the first reference signal based on the number of transmissions or the number of repetitions, and sends the first reference signal in the updated transmission mode. Optionally, the UE may report its own synchronization status (for example, whether the current UE is in a downlink out-of-synchronization state) to the network-side device. The synchronization status indicates whether the UE is in a synchronized state, and may also include information such as the timing offset, frequency offset, and clock synchronization deviation of the UE. The magnitudes and levels of these information values can also be used to measure the synchronization status of the UE. Exemplarily, if the synchronization deviation value is too large, it indicates that the current UE is in a downlink out-of-synchronization state or close to an out-of-synchronization state. The network-side device may then send the first reference signal or send the first indication information including the transmission indication of the first reference signal according to the reported auxiliary information. Optionally, the UE may report the latest time (for example, Timeposition or time offset) at which it expects to receive the first reference signal as auxiliary information to the network-side device, so that the network-side device sends the first reference signal to the UE before this latest time.

[0187] In an optional embodiment, the QCL information includes at least one of the following:

[0188] SSB index;

[0189] Reference signal information RS info.

[0190] The QCL information can be used by the network-side device to determine the beam direction of the first reference signal. In specific implementation, the UE may report the QCL information as auxiliary information to the network-side device, so that the network-side device sends the first reference signal in a specific beam direction to the UE according to the QCL information. Optionally, the QCL information may include the SSB index, and the SSB index represents a specific SSB signal in the SSB set. The QCL information may include RS info, and the RS info is used to indicate the corresponding SSB index.

[0191] In an optional embodiment, the decoding information of the UE includes at least one of the following:

[0192] Decoding success rate;

[0193] Decoding failure rate;

[0194] ACK rate;

[0195] NACK rate;

[0196] Number of ACKs;

[0197] Number of NACKs.

[0198] Optionally, the network - side device sends data to the UE, and the UE decodes the received data. When the decoding success rate of the UE is low, it indicates that the UE may need to perform synchronization to adjust the synchronization state and improve the decoding success rate. The UE reports its own decoding information as auxiliary information to the network - side device. The network - side device obtains the decoding success rate of the current UE based on the decoding information of this UE. If the current decoding success rate of the UE is not high, the network - side device sends a first reference signal or a first indication message to the UE.

[0199] In an optional embodiment, the energy - saving information of the UE includes at least one of the following:

[0200] Energy - saving level;

[0201] Battery power or remaining battery power;

[0202] Discontinuous reception CDRX information in the connected state.

[0203] In specific implementation, the UE can report its own energy - saving information as auxiliary information to the network - side device, so that the network - side device determines whether to send a first reference signal or a first indication message according to the energy - saving information of this UE. Exemplarily, if the energy - saving level of the UE is high, the network - side device sends the first reference signal to this UE with a larger transmission period. If the energy - saving level of the UE is low, the network - side device sends the first reference signal to this UE with a smaller transmission period.

[0204] In an optional embodiment, the auxiliary information reported by the UE is transmitted through at least one of the following:

[0205] Physical Uplink Control Channel PUCCH;

[0206] Physical Uplink Shared Channel PUSCH;

[0207] Wake - up Signal WUS.

[0208] In specific implementation, the auxiliary information reported by the UE may be carried by the above-mentioned signaling. Exemplarily, the auxiliary information may be used as a new type of uplink control information (UCI) and reported by PUCCH signaling. Alternatively, it may be carried on a Medium Access Control Control Element (MAC CE) and reported by the PUSCH channel. It can be understood that the amount of information carried by the WUS signal is generally small and can be used to directly instruct the network-side device to send the first reference signal or change the transmission period of the first reference signal.

[0209] In an optional embodiment, the priority of the auxiliary information reported by the UE satisfies at least one of the following:

[0210] The priority of the auxiliary information transmitted through PUCCH is the target priority;

[0211] The priority of the auxiliary information transmitted through PUSCH is determined according to the priority of PUSCH;

[0212] The priority of the auxiliary information reported by the UE is determined according to the information carried by the auxiliary information reported by the UE.

[0213] In specific implementation, for different auxiliary information reported by different UEs, the priority of the auxiliary information may be determined based on the priority of the transmission signaling carrying the auxiliary information, or based on the information carried in the auxiliary information. Exemplarily, if the PUCCH signaling is set to a high priority, correspondingly, the signaling transmitted through PUCCH is determined to be of high priority. Or, if the priority of [information not clear in the original] is set to A and the priority of the measurement information is set to B, with A prior to B, then the auxiliary information carrying the indication information directly triggering the transmission of the first reference signal has a higher priority than the auxiliary information carrying the measurement information. Optionally, the priority of the reporting signaling (such as PUCCH, PUSCH) of the auxiliary information may be predefined by the protocol, preconfigured by the network-side device, or determined by the configuration of the network-side device.

[0214] In an optional embodiment, the auxiliary information may be used as a new type of UCI and reported by PUCCH signaling, and the UCI type priority satisfies at least one of the following:

[0215] HARQ-ACK > auxiliary information reported by the UE > Scheduling Request (SR) > CSI with higher priority > CSI with lower priority;

[0216] UE-assisted information > HARQ-ACK > SR > CSI with higher priority > CSI with lower priority;

[0217] HARQ-ACK > SR > UE-assisted information > CSI with higher priority > CSI with lower priority;

[0218] HARQ-ACK > SR > CSI with higher priority > UE-assisted information > CSI with lower priority;

[0219] HARQ-ACK > SR > CSI with higher priority > CSI with lower priority > UE-assisted information.

[0220] Optionally, if the UE-assisted information is divided into high priority and low priority, the priority positions of the high-priority UE-assisted information and the low-priority assisted information may be different. For example, the high-priority assisted information > CSI with higher priority, while the low-priority assisted information < CSI with lower priority.

[0221] In an optional embodiment, the network-side device sends the first reference signal or a transmission indication of the first reference signal when at least one of the following conditions is met, including:

[0222] The measurement results corresponding to the measurement objects reported by all or at least some of the UEs reporting the assisted information are less than a threshold;

[0223] The UE requests the network-side device to send the first reference signal or change the transmission period of the first reference signal;

[0224] The number of UEs greater than N or the proportion greater than Q request the network-side device to send the first reference signal or change the transmission period of the first reference signal, where N > 0 and Q > 0 and Q < 1;

[0225] There is downlink data arriving for the UE that requests the network-side device to send the first reference signal. Optionally, when there is downlink data arriving for the UE, it means that the network-side device will send data to the UE and the UE needs to maintain a good synchronization state. Therefore, in this case, the network-side device sends the first reference signal or a transmission indication of the first reference signal to enable the UE to perform a synchronization operation.

[0226] It should be noted that the measurement result corresponding to the measurement object reported by the UE may also refer to at least one of the timing offset value, the frequency offset value, and the clock synchronization deviation value.

[0227] In an optional embodiment, the network side device pauses sending the first reference signal or sends an indication of pausing the sending of the first reference signal when at least one of the following conditions is met:

[0228] The UE reporting the auxiliary information indicates to stop receiving the first reference signal;

[0229] The UE reporting the auxiliary information indicates CDRX information or state transition information;

[0230] The measurement result corresponding to the measurement object reported by all or at least part of the UEs reporting the auxiliary information is greater than a threshold;

[0231] All or at least part of the UEs reporting the auxiliary information indicate that they no longer need the first reference signal;

[0232] All or at least part of the UEs reporting the auxiliary information indicate that they can rely on other cells for synchronization;

[0233] The network side device no longer receives the auxiliary information reported by the UE;

[0234] The transmission time window of the first reference signal ends;

[0235] The end transmission resource position of the first reference signal is reached;

[0236] After sending T times with the maximum transmission period, where T > 0. Exemplarily, referring to the above Embodiment 3-1 or Embodiment 3-2, the network side device gradually extends the transmission period of the first reference signal until the length of the transmission period reaches the period threshold, and the network side device pauses sending the first reference signal or sends an indication of pausing the sending of the first reference signal.

[0237] It should be known that different transmission times of the first reference signal will result in different energy consumption of the network side device or the UE. The following embodiments further illustrate the transmission time of the first reference signal sent by the network side device.

[0238] In an optional embodiment, the transmission time of the first reference signal sent by the network side device is determined according to at least one of the following:

[0239] The reference transmission time of the first reference signal;

[0240] The time offset.

[0241] In this embodiment, the transmission time of the first reference signal sent by the network-side device, that is, the start time of sending the first reference signal. Optionally, the network-side device starts to send the first reference signal at the position of the reference point (i.e., the reference transmission time) + time offset. This mainly applies to the following situations:

[0242] Situation 1: After receiving the auxiliary information reported by the UE, the network-side device sends the first reference signal as soon as possible without considering the transmission time of the first reference signal determined for other UEs. In this case, the first reference signal is similar to UE-specific. However, if multiple UEs request the first reference signal (report auxiliary information to this network-side device) at different times, the network-side device needs to send multiple sets of first reference signals, which is not conducive to the network-side device saving energy consumption.

[0243] Situation 2: After receiving the auxiliary information reported by the UE, the network-side device determines a start transmission time (i.e., the transmission time) of the first reference signal according to the auxiliary information reported by different UEs. In this case, the time offset indicated for different UEs may be different to facilitate the unified understanding of the start transmission time of the first reference signal by the UEs.

[0244] Situation 3: The network-side device determines a start transmission time (i.e., the transmission time) of the first reference signal. The time offset indicated for different UEs may be different to facilitate the unified understanding of the transmission time of the first reference signal.

[0245] Situation 4: The transmission resource position where the network-side device sends the first reference signal belongs to a candidate transmission resource position of a pre-configured position.

[0246] The network-side device does not start to send the first reference signal at the position of the reference point + time offset. This mainly applies to the following situations:

[0247] Situation 5: The time offset is indicated by the UE and represents an expected transmission resource position of the first reference signal. However, in order to save power as much as possible, the network-side device determines a suitable transmission resource position of the first reference signal for the requests (reported auxiliary information) of multiple UEs. Therefore, for some UEs, the network-side device may not send the first reference signal at the position of the reference point + time offset. In this case, for these UEs, they need to search for the first reference signal in the time domain from the position of the reference point + time offset all the time, resulting in a certain waste of power consumption.

[0248] Case 6: The network device always sends the first reference signal at the candidate transmission resource positions of the pre-configured first reference signal, and the reference point + time offset is used to determine at which specific candidate transmission resource position the network device sends the first reference signal. For example, the network device will send the first reference signal at the next candidate transmission resource position that meets a certain processing time after the reference point + time offset. The transmission method in Case 6 can save more power of the UE compared with Case 5.

[0249] In an optional embodiment, the reference transmission time of the first reference signal is determined according to at least one of the following:

[0250] The time when the network device sends the first indication information;

[0251] The time when the UE reports the auxiliary information;

[0252] The candidate transmission times pre-defined by the protocol or pre-configured by the network device.

[0253] In specific implementation, there are two types of reference transmission times (transmission positions) of the first reference signal. One is flexible transmission, that is, the reference transmission time determined according to the time when the network device sends the first indication information; or, the reference transmission time determined according to the time when the UE reports the auxiliary information. The other is to send at the pre-configured time or resource position, that is, the protocol pre-defines or the network device pre-configures a candidate transmission time or candidate transmission resource position of the first reference signal. Exemplarily, it is indicated by a bitmap, or a starting time or resource position is determined by DFN / SFN index + symbol index, and then repeated according to a pre-configured period, which is the candidate transmission time or candidate transmission resource position of the first reference signal. When the first reference signal is sent, it is always sent at the candidate transmission time or candidate transmission resource position.

[0254] In an optional embodiment, the time offset time offset is determined according to at least one of the following:

[0255] The processing time of the UE for processing the first indication information;

[0256] The processing time of the network device for processing the HARQ-ACK sent by the UE;

[0257] The preparation time of the network device for sending the first reference signal;

[0258] The processing time of the network device for processing the auxiliary information reported by the UE;

[0259] The first time, where the first time represents an additional processing time predefined by the protocol;

[0260] The second time, where the second time represents the time reserved for the unified transmission of the first reference signal;

[0261] Indicated by the UE;

[0262] Indicated by the network side device;

[0263] Predefined by the protocol;

[0264] Preconfigured by the network side device.

[0265] In the embodiments of the present application, the preparation time can all be expressed as the processing time. Exemplarily, the preparation time for the network side device to send the first reference signal can also be interpreted as the processing time for the network side device to send the first reference signal. Based on the above embodiments, for the transmission time of the first reference signal sent by the network side device, one of the following four solutions is satisfied.

[0266] Solution 1: Based on the above situation 1, after the network side device receives the auxiliary information reported by any UE, it triggers the transmission of the first reference signal, without considering the transmission time of the determined first reference signal of other UEs. In this case, let the transmission time (i.e., the starting transmission time) of the first reference signal sent by the network measurement device be n1 + k1, the reference transmission time (the indication time for the network side device to send the first reference signal, that is, the time when the network side device sends the first indication information) be n1, and the time offset be k1. In Solution 1, k1 includes at least one of the following:

[0267] The processing time for the UE to process the first indication information;

[0268] The processing time for the network side device to process the HARQ-ACK sent by the UE; Specifically, if the network side device first sends the first indication information (including the transmission indication of the first reference signal), and then sends the first reference signal, then considering that the network side device sends the first indication information to the UE, and after the UE successfully receives and understands it, it will send HARQ-ACK to the network side device. Therefore, the processing time for the network side device to process HARQ-ACK is included in k1.

[0269] The preparation time for the network side device to send the first reference signal;

[0270] The first time.

[0271] Optionally, k1 can be indicated by the network side device, predefined by the protocol, or preconfigured by the network side device.

[0272] Solution 2: Based on the above Situation 1, after the network-side device receives the auxiliary information reported by any UE, it triggers the transmission of the first reference signal without considering the transmission time of the determined first reference signal of other UEs. In this case, the network-side device may not send the first indication information and directly send the first reference signal. In this case, let the transmission time (i.e., the starting transmission time) of the first reference signal sent by the network-side device be n2 + k2, the reference transmission time (i.e., the time when the UE reports the auxiliary information) be n2, and the time offset be k2. In Solution 2, k2 includes at least one of the following:

[0273] The processing time of the network-side device for the auxiliary information reported by the UE;

[0274] The preparation time of the network-side device for sending the first reference signal;

[0275] The first time.

[0276] Optionally, k2 can be indicated by the UE, pre-defined by the protocol, or pre-configured by the network-side device.

[0277] It should be noted that in this case, the network-side device may also send the first indication information. For example, it only indicates the transmission information of the first reference signal for the terminal that currently sends the auxiliary information. In this case, the transmission time of the first reference signal sent by the network-side is n2 + k2, and it may also be n1 + k1 (as defined in Solution 1).

[0278] Solution 3: Based on the above Situation 2, after the network-side device receives the auxiliary information reported by multiple UEs, for energy conservation, it determines a unified starting transmission time (i.e., the transmission time) of the first reference signal according to the auxiliary information reported by different UEs. Otherwise, the UE may blindly search for the first reference signal in advance, resulting in wasted power consumption. In this case, the network-side device may not send the first indication information and directly send the first reference signal. In this case, let the transmission time (i.e., the starting transmission time) of the first reference signal sent by the network-side device be n3 + k3, the reference transmission time (i.e., the time when the UE reports the auxiliary information) be n3, and the time offset be k3. In Solution 3, k3 includes at least one of the following:

[0279] The processing time of the UE for the first indication information;

[0280] The preparation time of the network-side device for sending the first reference signal;

[0281] The first time;

[0282] The second time.

[0283] Optionally, k3 is indicated by the UE, indicated by the network side device, predefined by the protocol, or preconfigured by the network side device.

[0284] Solution 4: Based on the above-mentioned Case 2, after the network side device receives the auxiliary information reported by multiple UEs, for energy saving, according to the auxiliary information reported by different UEs, it determines a unified starting transmission time (i.e., transmission moment) of the first reference signal. Otherwise, the UE may blindly search for the first reference signal in advance, resulting in wasted power consumption. In this case, let the transmission moment (i.e., starting transmission time) of the network side device sending the first reference signal be n4 + k4, the reference transmission moment (the moment when the network side device sends the first indication information) be n4, and the time offset be k4.

[0285] In Solution 4, k4 includes at least one of the following:

[0286] The processing time of the network side device for processing the auxiliary information reported by the UE;

[0287] The processing time of the UE for processing the first indication information;

[0288] The processing time of the network side device for processing the HARQ-ACK sent by the UE; Specifically, if the network side device first sends the first indication information (including the transmission indication of the first reference signal), and then sends the first reference signal, then considering that the network side device sends the first indication information to the UE, and after the UE successfully receives and understands it, it will send HARQ-ACK to the network side device. Therefore, k4 includes the processing time of the network side device for HARQ-ACK.

[0289] The preparation time of the network side device for sending the first reference signal;

[0290] The first time;

[0291] The second time.

[0292] Optionally, k4 is indicated by the UE, indicated by the network side device, predefined by the protocol, or preconfigured by the network side device.

[0293] The second aspect of the embodiments of the present application provides an information transmission method, which is applied to a user equipment UE. Refer to Figure 4 , Figure 4 shows a step flowchart of another information transmission method. As Figure 4 shown, the information transmission method includes:

[0294] The user equipment UE performs at least one of the following:

[0295] Step S401: Report auxiliary information to the network-side device, where the auxiliary information is used to trigger the network-side device to send a first reference signal;

[0296] Step S402: Determine whether to receive the first reference signal sent by the network-side device according to the first information;

[0297] Step S403: After receiving the first indication information related to the first reference signal sent by the network-side device, receive the first reference signal sent by the network-side device, where the first indication information includes at least one of the following:

[0298] The transmission indication of the first reference signal;

[0299] The pause transmission indication of the first reference signal;

[0300] The transmission mode of the first reference signal.

[0301] In the related art, the network-side device mainly sends reference signals to each UE at a fixed period for synchronization, measurement (cell measurement, channel measurement), phase tracking, demodulation, etc. However, in actual applications, the method of sending reference signals at a fixed period does not consider the actual needs of the UE and is not conducive to network energy saving. To solve the above problems, the embodiments of the present application propose that the UE can, according to its own actual situation, when determining the need to synchronize with the network-side device or perform measurements and other actions, execute Step S401, where the UE reports auxiliary information to the network-side device, thereby triggering the network-side device to send a first reference signal or a first indication information (to indicate the transmission / pause transmission of the first reference signal or update the transmission period of the first reference signal), realizing the on-demand transmission of the reference signal and achieving the purpose of energy saving for the network-side device.

[0302] Moreover, the network-side device can send the first indication information (including the transmission indication of the first reference signal) after receiving the auxiliary information reported by the UE, thereby enabling the UE to execute Step S403. Specifically, the UE returns a HARQ-ACK message to the network-side device according to the received first indication information, the network-side device sends the first reference signal, and the UE receives the first reference signal. During this process, the network-side device can send the first indication information related to the first reference signal to indicate the transmission, pause transmission, and update of the transmission mode of the first reference signal, thereby flexibly controlling the transmission of the reference signal.

[0303] In an optional embodiment, within a pre-defined period of time pre-configured by the network side, or during the transmission behavior or transmission period of the first reference signal of a network side device once, after the UE is supposed / expected / assumed to have received the first reference signal, it does not need to receive it anymore, or it is supposed / expected / assumed to receive the first reference signal only once. The transmission behavior of the first reference signal of the network side device once includes: transmitting one or more first reference signals. Exemplarily, the transmission behavior of the first reference signal of the network side device once corresponds to one time of transmitting the first reference signal in a certain transmission mode triggered by the network side device or the UE.

[0304] There is no sequence among the above steps S401 - S403, and they can be set according to actual requirements.

[0305] In an optional embodiment, the UE receiving the first reference signal sent by the network side device includes:

[0306] The UE determines the transmission moment of the first reference signal according to at least one of the following: the reference transmission moment of the first reference signal; the time offset.

[0307] The UE receives or measures the first reference signal at the transmission moment of the first reference signal.

[0308] In this embodiment, after the UE executes step S401 and reports auxiliary information to the network side device to trigger the network side device to send the first reference signal, the UE needs to determine the transmission moment of the first reference signal, so as to receive the first reference signal sent by the network side device at this transmission moment. In one possibility, the UE can determine the transmission moment according to the reference transmission moment and the time offset. The specific method for determining the transmission moment has been described in the above embodiment regarding the transmission moment, and will not be elaborated in this embodiment. In another possibility, the UE can directly determine the transmission moment according to the indication of the network side device, the pre-configuration of the network side device, or the transmission period or transmission mode of the first reference signal pre-defined by the protocol. The embodiment of the present application proposes to report auxiliary information from the UE to the network side device to trigger the transmission of the first reference signal, search for the first reference signal at the determined transmission moment to receive the first reference signal, and realize the on-demand transmission of the first reference signal. This can avoid affecting the synchronization, measurement, phase tracking, demodulation, etc. of the UE in the background where the network side device uses an overly large period or time interval to send the first reference signal for energy saving, or directly does not send the reference signal.

[0309] In an optional embodiment, the reference transmission moment of the first reference signal is determined according to at least one of the following:

[0310] The time when the network - side device sends the first indication information;

[0311] The time when the UE reports the auxiliary information;

[0312] Candidate transmission times predefined by the protocol or pre - configured by the network - side device.

[0313] In an optional embodiment, the time offset is determined according to at least one of the following:

[0314] The processing time of the UE for processing the first indication information;

[0315] The processing time of the network - side device for processing the HARQ - ACK sent by the UE;

[0316] The preparation time of the network - side device for sending the first reference signal;

[0317] The processing time of the network - side device for processing the auxiliary information reported by the UE;

[0318] A first time, where the first time represents an additional processing time predefined by the protocol;

[0319] A second time, where the second time represents the time reserved for unified SSB transmission;

[0320] Indicated by the UE;

[0321] Indicated by the network - side device;

[0322] Predefined by the protocol;

[0323] Pre - configured by the network - side device.

[0324] It can be understood that the time offset is a value greater than or equal to 0. The time unit may be a radio frame, a sub - frame, a time slot, a mini - slot, a second, a millisecond, etc.

[0325] In an optional embodiment, the UE determines whether to receive the first reference signal sent by the network - side device according to the first information, including:

[0326] The UE performs a first action according to the first information, and the first action includes at least one of the following:

[0327] Receive the first reference signal;

[0328] Send a first transmission object, where the first transmission object includes at least one of the following: PUCCH, PUSCH, physical random access channel PRACH, sounding reference signal SRS;

[0329] Receive a first receiving object, where the first receiving object includes at least one of the following: Physical Downlink Control Channel (PDCCH), Physical Downlink Shared Channel (PDSCH), CSI-RS, TRS, PTRS.

[0330] In this embodiment, during the process of the UE receiving the first reference signal sent by the network side device, conflict problems such as at least partial overlap between the transmission position of the first reference signal and the first transmission object or the first receiving object are likely to occur. Specifically, when the network side device sends the first reference signal, at the resource position of the first reference signal, the UE may have or be scheduled for other UL transmissions, or DL receptions. Due to the half-duplex reason, if there is a conflict with the UL transmission, the UE needs to choose whether to receive the first reference signal or perform the uplink transmission (transmit the first transmission object), and if there is a conflict with the DL reception, from the perspective of reliability, the UE may need to choose whether to receive the first reference signal or perform other DL receptions (receive the first receiving object). Therefore, it is necessary to determine the behavior to be preferentially executed according to the conditions satisfied by the current actual situation or the first information.

[0331] In an optional embodiment, the first information on which the UE performs the first behavior includes at least a first condition and first target information; the UE performs the first behavior according to the first information, including at least one of the following:

[0332] The UE preferentially receives the first reference signal according to the first target information;

[0333] When the first condition is satisfied, the UE preferentially receives the first reference signal, and the first condition includes at least one of the following:

[0334] The UE has requested the first reference signal from the network side device; it can be understood that since it is the UE that requests the transmission behavior, the UE preferentially receives the first reference signal;

[0335] The first reference signal is the first time sent by the network side device;

[0336] The measurement result of the UE on the first object is less than a threshold; it can be understood that if the measurement result of the first object is less than the threshold, it indicates that the UE needs to receive the first reference signal for at least one of the behaviors such as synchronization, measurement, demodulation, and phase tracking. Therefore, the UE preferentially receives the first reference signal.

[0337] The UE is no longer synchronized;

[0338] The UE is approaching out-of-synchronization; exemplarily, if the UE is no longer synchronized or is approaching out-of-synchronization, the first condition is satisfied, and the first reference signal is preferentially received. If the UE has a good synchronization state, receiving the first reference signal is of low priority, and instead, the first reception object is preferentially received or the first transmission object is transmitted.

[0339] The transmission period of the first reference signal is greater than or equal to the longest transmission period or the longest transmission interval of the first reference signal supported by the synchronization capability of the UE;

[0340] The transmission period of the first reference signal is greater than a period threshold;

[0341] The first reference signal is not received within a first time window or a second time period; the first time window and the second time period are determined according to the synchronization requirements, measurement requirements, or status of the UE.

[0343] The transmission time of the first reference signal at least partially overlaps with the reception time of the first reception object;

[0344] The first transmission object or the first reception object is control information;

[0345] The first transmission object or the first reception object contains control information;

[0346] The priority of the uplink UL is greater than or equal to a first threshold or less than or equal to a second threshold; it can be understood that whether to preferentially receive the first reference signal is determined according to the pre-configured priority.

[0347] The priority of the downlink DL is greater than or equal to a third threshold or less than or equal to a fourth threshold; it can be understood that whether to preferentially receive the first reference signal is determined according to the pre-configured priority.

[0348] The transmission time of the first reference signal at least partially overlaps with the transmission time of the first transmission object that satisfies a third condition;

[0349] The transmission time of the first reference signal at least partially overlaps with the reception time of the first reception object that satisfies the third condition;

[0350] The third condition includes at least one of the following:

[0354] The first transmission object or the first reception object is for retransmission;

[0355] The first target information includes at least one of the following:

[0356] Whether the transmission resource of the first transmission object or the first reception object is dynamic grant DG; Exemplarily, when the transmission resource of the first transmission object or the first reception object is DG, the first transmission object is preferentially transmitted or the first reception object is preferentially received. It can be understood that at this time, it is considered that the priority of transceiver on the dynamically scheduled resource is higher. Of course, if it is pre-configured or the terminal determines that the priority of transceiver on the dynamically scheduled resource is lower, then the first reference signal is preferentially received.

[0357] Whether the transmission resource of the first transmission object or the first reception object is configured grant CG; Exemplarily, when the transmission resource of the first transmission object or the first reception object is CG, receiving the first reference signal takes precedence over transmitting the first transmission object or receiving the first reception object. It can be understood that at this time, it is considered that the priority of transceiver on the statically scheduled resource is lower. Of course, if it is pre-configured or the terminal determines that the priority of transceiver on the statically scheduled resource is higher, then the first transmission object is preferentially transmitted or the first reception object is preferentially received.

[0358] Whether the first reference signal is triggered by the UE; Exemplarily, if the first reference signal is triggered by the UE (the UE reports auxiliary information to trigger the network-side device to send the first reference signal), then the first reference signal is preferentially received.

[0359] The reception purpose of the first reference signal; Exemplarily, if the reception purpose of the first reference signal is for synchronization (or activation, de-measurement), then the first reference signal is preferentially received, and if the reception purpose of the first reference signal is for measurement, then the first reference signal is not preferentially received.

[0370] The first reference signal is not the first time sent by the network side device; Exemplarily, when the first reference signal is an SSB, and the currently received SSB belongs to the Lth SSB period, L>1; It can be understood that at this time, the UE may have received the first reference signal. That is, in a period of time or a first reference signal transmission behavior or transmission cycle of the network side device, the UE should / expect / assume that after receiving the first reference signal, it does not need to receive it again, or should / expect / assume to only receive the first reference signal once.

[0385] The first transmission object or the first reception object is located in the Scell;

[0386] The first transmission object or the first reception object is located in the Pcell; Exemplarily, it can be set that when the first transmission object or the first reception object is located on the Pcell, transmitting the first transmission object or receiving the first reception object takes precedence over receiving the first reference signal.

[0387] The first transmission object or the first reception object is a first transmission; It can be understood that at this time, the priority of the first transmission is considered to be higher.

[0388] The first transmission object or the first reception object is a retransmission; It can be understood that at this time, the priority of the retransmission is considered to be higher because the first transmission has not been successfully received.
