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

If the name of the core network equipment mentioned in the embodiments of this application changes in subsequent protocol versions (such as 6G), it is also within the scope of protection of this application.

[0063] Optionally, the core network device can be implemented by one or more functional modules in a single device, or by multiple devices together, and this is not specifically limited in the embodiments of the present application. It is understood that the above-mentioned functional modules can be network elements in hardware devices, or software functional modules running on dedicated hardware, or virtualized functional modules instantiated on a platform (e.g., a cloud platform).

[0064] Figure 2 shows a gNB system architecture applicable to this embodiment. As shown in Figure 2, the NR access network splits the gNB into a central unit (gNB-CU) and distributed units (gNB-DU), with the central unit and the distributed units connected via the F1 interface. Each gNB contains only one central unit (CU) and one or more distributed units (DUs), each of which contains one or more cells. The CU includes the Packet Data Convergence Protocol (PDCP) and higher-level protocol stacks, while the DU includes the protocol stack below the PDCP layer: Radio Link Control (RLC), Medium Access Control (MAC), and Physical Layer (PHY). On the control plane, the CU includes Radio Resource Control (RRC) and the control-plane PDCP (PDCP-C). On the user plane, the CU includes the Service Data Adaptation Protocol (SDAP) and the user-plane PDCP (PDCP-U).

[0065] 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 Orthogonal Frequency Division Multiplexing (OFDM) symbol timing and frequency synchronization; then detect the Secondary Synchronization Signal (SSS) to obtain the other part of the physical cell ID, i.e. Get the complete physical cell ID, that is Right now Then, the user equipment detects the physical broadcast channel PBCH and demodulates the reference signal DMRS of the PBCH to obtain the system frame number and SSB index, and further obtains the radio frame (subframe) timing.

[0066] The SSB period in NR is configured in the first system information block (SIB1), which may be 5ms, 10ms, 20ms, 40ms, 80ms, or 160ms. During initial access, if the UE has not received SIB1, it will search for SSB according to the default 20ms period. SSB does not appear once at a certain interval, but appears several times in a half-frame at a certain interval. This is designed for beam scanning. Each of the several SSBs corresponds to a direction of beam scanning. In the end, there will be an SSB in each direction. These several SSBs are called an SSB set. All SSBs in an SSB set must be in the same half-frame.

[0067] In related technologies, multi-carrier is a typical operation of 5G NR networks, which is used to enhance network-side capacity. For Pcell or PScell, the base station must send periodic SSBs, and the SSB period must be less than or equal to 20ms to be successfully searched by the user equipment in the initial search. For intra-band Scells, the base station can send SSBs, in which case the SSB-related parameters are configured when the Scell ​​is added; or it can not send SSBs, in which case the SSB-related parameters are not configured when the Scell ​​is added, and the terminal obtains timing through the SSB on the Pcell. For inter-band Scells, the base station must send SSBs and configure the SSB-related parameters when the Scell ​​is added.

[0068] The majority of NR network power consumption comes from base stations, with 90% of this coming from the active antenna unit (AAU). Due to higher frequency bands, wider bandwidth, and more TRXs, the power consumption of a single NR base station is currently 3-4 times higher than that of LTE. Furthermore, in terms of operating expenses (OPEX), base station electricity costs account for nearly 20% of the total network operating costs. For some operators, electricity costs account for more than half of their total profits. Therefore, energy conservation in NR networks has become even more critical to achieving the significant success of 5G. Depending on actual load conditions, base stations can implement varying degrees of energy conservation measures, such as shutting down base stations, shutting down carriers / cells, shutting down channels, shutting down SSBs / beams, shutting down antennas / panels, cell discontinuous transmission (DTX) and / or discontinuous reception (DRX), and adapting channel state information (CSI).

[0069] In related technologies, SSBs are continuously transmitted at a fixed period. When there are few user devices connected to a cell, requiring a base station to continuously transmit SSBs at a fixed period is detrimental to energy conservation for network-side equipment, particularly for base stations serving as secondary cells. While certain conditions have been defined that allow SSB-less cells to not transmit SSBs, some Scells that do not meet these conditions still need to periodically transmit SSBs. To further achieve network energy conservation, it is necessary to consider a mechanism for transmitting SSBs based on actual UE demand in these cells.

[0070] An embodiment of the present application provides an information transmission method that can send a reference signal (such as SSB) on demand, thereby achieving the purpose of energy saving for network-side equipment.

[0071] The following describes in detail an information transmission method provided by an embodiment of the present application through some embodiments and their application scenarios in combination with the accompanying drawings.

[0072] A first aspect of an embodiment of the present application provides an information transmission method. Referring to FIG. 3 , FIG. 3 shows a flowchart of steps of an information transmission method. As shown in FIG. 3 , the information transmission method may include:

[0073] The network-side device performs at least one of the following:

[0074] Step S301: sending a first reference signal in a first sending mode;

[0075] Step S302: Send a first reference signal according to the auxiliary information reported by the user equipment UE;

[0076] Step S303: Send first indication information related to the first reference signal, where the first indication information includes at least one of the following:

[0077] an indication of sending the first reference signal;

[0078] an indication of suspending transmission of the first reference signal;

[0079] The first sending mode.

[0080] It should be noted that the network side device that sends the reference signal, the network side device that sends the indication information, and the network side device that receives the UE auxiliary information may be the same network side device or may not be the same network side device.

[0081] In one possible scenario, when the network-side device is an inactive secondary cell (Scell), if the inactive Scell ​​wants to trigger the transmission of a first reference signal, it needs to notify the UE through other cells (e.g., a cell in the active state), otherwise the UE will not receive the first reference signal on the inactive Scell. Optionally, the inactive Scell ​​needs to first send relevant information about the first reference signal to other cells, which are then forwarded or notified to the UE by the other cells. The UE then sends feedback information to the other cells, which then notify the inactive Scell. Alternatively, the UE's feedback information is directly sent to the inactive Scell, thereby helping the inactive Scell ​​determine whether to send the first reference signal and the time to send the first reference signal.

[0082] The relevant information of the first reference signal includes at least one of the following:

[0083] triggering the sending of a first reference signal;

[0084] Indicates a range within which the first reference signal is sent;

[0085] a destination terminal to which the first reference signal is sent;

[0086] The sending time of the first reference signal.

[0087] Among them, other communities include at least one of the following:

[0088] Primary cell Pcell of the destination terminal;

[0089] Cells in the active state;

[0090] active Scell.

[0091] The active cell includes at least one of an active primary cell (Pcell) and an active secondary cell (Pcell). Information exchange between the inactive Scell ​​and other cells is performed via at least one of the following: an Xn interface, an NG interface, an F1 interface, or wireless backhaul technology.

[0092] Optionally, the first reference signal represents a reference signal used for transmission between the user equipment UE and the network side device, 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 the terminal in Figure 1. In an embodiment of the present application, the UE may be the terminal device 11 in Figure 1. For an example of the terminal device 11, please refer to the above text. It may be a UE accessing a primary cell (Pcell) or a UE accessing a secondary cell (Scell), and is not limited in this embodiment. In some embodiments, the first reference signal is an SSB; in other embodiments, the first reference signal includes at least one of an SSB, a demodulation reference signal DMRS, a channel state information reference signal CSI-RS, a phase reference signal TRS, and a phase tracking reference signal PTRS.

[0093] It should be noted that the network-side device may include a satellite-based network-side device, such as a satellite-based base station, or a ground-based network-side device, such as a ground-based base station. In this embodiment, the network-side device may execute step S301, whereby the network-side device autonomously transmits a first reference signal to the UE according to a configured first transmission mode, so that the UE synchronizes using the received first reference signal. The first transmission mode may differ from a fixed transmission period, for example, by transmitting the reference signal at gradually increasing time intervals, thereby reducing unnecessary reference signal transmissions and achieving energy conservation for the network-side device.

[0094] In this embodiment, the network-side device may further perform step S302, where the network-side device transmits a first reference signal after receiving the auxiliary information reported by the UE, so as to interact between the UE and the network-side device. Optionally, the UE may, based on its actual situation, report the auxiliary information when detecting that synchronization with the network-side device is required, so that the network-side device transmits a first reference signal (e.g., an SSB signal), thereby achieving synchronization between the UE and the network-side device based on the first reference signal. As a result, there is no need for the network-side device to transmit the first reference signal to the UE for synchronization according to a fixed period, thereby achieving the purpose of transmitting the first reference signal according to the actual needs of the UE, and achieving energy saving of the network-side device.

[0095] In this embodiment, the network side device may further perform step S303, where the network side device may send first indication information related to the first reference signal to control the transmission of the first reference signal, suspend the transmission, and update the transmission mode of the first reference signal according to the first indication information, thereby flexibly controlling the transmission of the reference signal. In an optional embodiment, the step S303, wherein the sending of the first indication information related to the first reference signal includes:

[0096] Send first indication information related to the first reference signal according to the auxiliary information reported by the UE.

[0097] In this embodiment, the network side device can send indication information after receiving the auxiliary information reported by the UE, and then send the first reference signal, suspend sending, and update the sending mode of the first reference signal according to the indication information, thereby realizing flexible sending of the first reference signal according to the actual needs of the UE, so as to achieve the purpose of energy saving of the network side device.

[0098] Optionally, the first indication information may be explicitly or implicitly indicated by at least one of downlink control information (Downlink Control Information, DCI), medium access control protocol control element (Medium Access Control Control Element, MAC CE), RRC, and cell switch indication.

[0099] Exemplarily, the DCI may be an existing DCI, such as single-cell uplink scheduling DCI such as DCI 0_0 / 0_1 / 0_2 or 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, may be a scheduling DCI, may be a non-scheduling DCI, may be a new group common DCI or reuse of an existing group common DCI, such as DCI 2-9.

[0100] 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 the Scell ​​activation or Scell ​​deactivation MAC CE, such as a new MAC CE.

[0101] There is no specific order between the above steps S301-S303, and they can be set according to actual needs.

[0102] In specific implementations, for the above steps S301 and S303, there are multiple situations for the first sending mode. Different first sending modes will lead to certain differences in the information transmission methods proposed in the embodiments of this application. In an optional embodiment, the first sending mode includes at least one of the following:

[0103] a first transmission period of the first reference signal, wherein the first transmission period is greater than 160 milliseconds;

[0104] at least two different sending periods of the first reference signal;

[0105] the number of transmission cycles of the first reference signal;

[0106] a sending mode of the first reference signal, the sending mode being used to indicate a time domain interval or a number of transmissions within a time slot used for sending the first reference signal;

[0107] Transmission mode information of the first reference signal, the transmission mode information being used to represent at least one of the following: a transmission mode with gradually increasing time intervals, and a transmission mode with a constant transmission period;

[0108] The sending time information of the first reference signal includes at least one of the following: a sending time window, a sending duration, a starting sending resource position, and an ending sending resource position of the first reference signal.

[0109] The transmission period represents the time interval at which the network-side device transmits the first reference signal at fixed intervals. At least two different transmission periods indicate that the transmission period is adjustable and can be adjusted from one transmission period (for example, a fixed period used for continuous transmission at a fixed period in the related art, or a period different from the fixed period) to another transmission period. The number of transmission periods represents the number of periods at which the network-side device transmits the first reference signal according to the transmission period. For example, if the transmission period is 10 ms and the number of transmission periods is 5, 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 transmission periods. The transmission mode is used to indicate the time domain interval or number of transmissions within the slot (i.e., the time slot) used to transmit the first reference signal. For example, whether 2 or 3 first reference signals will be transmitted in a slot, whether the interval between each two is 2 symbols, or whether there is no interval, etc. The transmission time window indicates that the first reference signal is transmitted within a specified time window.

[0110] The following implementation manner further illustrates the information transmission method involved in step S301 and step S303 based on the different first sending modes in the above embodiments.

[0111] Implementation method 1-1

[0112] This embodiment describes that when the network side device executes step S301, the network side device sends the first reference signal according to a set fixed sending period. Exemplarily, the network side device sends the first reference signal once every 320ms (sending period).

[0113] In the first transmission mode: the transmission period of the first reference signal is a set constant value (so that the constant value as the period length can meet the synchronization / measurement and other requirements of all UEs), and the transmission mode information of the first reference signal is a transmission mode with a constant transmission period.

[0114] It is understood that the current maximum SSB transmission period is 160ms. If a longer transmission period is adopted, further energy conservation can be achieved. If a user device determines that its synchronization or measurement requirements cannot be met within this transmission period, it triggers the base station to send additional SSBs.

[0115] Implementation 1-2

[0116] This embodiment describes a scenario where the network device first executes step S303 and then executes step S301 (i.e., the network device first sends a first reference signal transmission instruction and then sends the first reference signal). The network device first sends the first indication information and then, based on the first reference signal transmission instruction or the first transmission mode in the first indication information, transmits the first reference signal with a fixed transmission period. In the first transmission mode, the transmission period of the first reference signal is a set constant value (such that the constant value, as a 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 a constant transmission period.

[0117] Implementation method 2-1

[0118] This embodiment describes that when the network-side device executes step S301, the network-side device sends a first reference signal according to a fixed sending period, suspends sending after reaching the set number of sending periods, waits for a first time, and then restarts sending the first reference signal with a fixed sending period and a fixed number of sending periods. The sending period and the number of sending periods may be predefined by the protocol or preconfigured by the network side. Exemplarily, the network-side device sends the first reference signal once every 160ms (sending period), suspends sending the first reference signal after sending a total of 5 times (number of sending periods), and restarts sending the first reference signal once every 160ms after waiting for 10s (first time).

[0119] In the first transmission mode: the transmission period of the first reference signal is a set constant value, the number of transmission periods of the first reference signal is a set constant value, and the transmission mode information of the first reference signal is a transmission mode with a constant transmission period.

[0120] Implementation method 2-2

[0121] This embodiment describes a case where the network side device first executes step S303 and then executes step S301 (i.e., the network side device first sends a sending 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 with a fixed sending period according to the sending indication of the first reference signal in the first indication information or the first sending mode. After reaching the set number of sending periods, the sending is suspended until the first time has passed, and then the sending of the first reference signal with a fixed sending period and a fixed number of sending periods is restarted. In the first sending mode: the sending period of the first reference signal is a set constant value, the number of sending periods of the first reference signal is a set constant value, and the sending mode information of the first reference signal is a sending mode with a constant sending period. Implementation 3-1,

[0122] This embodiment describes that 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, and the network side device suspends sending the first reference signal until the first time passes and then resumes sending the first reference signal according to the above-mentioned transmission mode.

[0123] In the first transmission mode, the transmission period of the first reference signal is a plurality of gradually increasing transmission periods. The number of transmission periods corresponding to transmission periods of different lengths may be the same or different. For example, the first reference signal P1 is transmitted with a transmission period of 20 ms, followed by P2 with a transmission period of 40 ms, and then P3 with a transmission period of 80 ms. Alternatively, P1, P2, and P3 may be different or the same. The transmission mode information of the first reference signal represents a transmission mode with gradually increasing time intervals.

[0124] Implementation method 3-2

[0125] This embodiment describes a case where the network-side device first executes step S303 and then executes step S301 (i.e., the network-side device first sends a sending 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 gradually extends the sending period of the first reference signal according to the sending indication of the first reference signal or the first sending mode in the first indication information until the length of the sending period reaches the period threshold. The network-side device suspends sending the first reference signal until the first time passes and then re-sends the first reference signal according to the above-mentioned sending mode. In the first sending mode: the sending period of the first reference signal is a plurality of gradually extended sending periods. The number of sending periods corresponding to sending periods of different sizes may be the same or different. The sending mode information of the first reference signal represents a sending mode with a gradually increasing time interval.

[0126] Implementation method 4-1

[0127] This embodiment describes that 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, and the network side device continues to send the first reference signal at the current maximum transmission period until the first time passes and the first reference signal is sent again according to the above-mentioned transmission mode.

[0128] In the first transmission mode: the transmission period of the first reference signal is a plurality of transmission periods that are gradually extended, and the number of transmission periods corresponding to transmission periods of different sizes may 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 send the first reference signal, first sending it twice with a transmission period of 20ms. When sending the first reference signal for the third or fourth time, the interval with the previous first reference signal becomes 40ms, which is equivalent to switching the transmission period of the first reference signal to 40ms, sending it twice, and then switching the transmission period to 80ms according to the same principle, until it is sent twice with the configured maximum transmission period, and the first reference signal is always sent with the maximum transmission period, for example, 640ms.

[0129] Implementation method 4-2

[0130] This embodiment describes a case where the network side device first executes step S303 and then executes step S301 (i.e., the network side device first sends the first indication information, i.e., the sending 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 gradually extends the sending period of the first reference signal according to the sending indication of the first reference signal or the first sending mode in the first indication information until the length of the sending period reaches the period threshold. The network side device keeps sending the first reference signal with the current maximum sending period until the network side device sends the first indication information (step S303), changes the sending period of the first reference signal according to the first sending mode included in the first indication information, or until a UE triggers the network side device to change the sending period (for example, the UE reports auxiliary information to the network side device, and the auxiliary information includes the new sending period of the first reference signal).

[0131] In an optional embodiment, the network side device sends the first reference signal or sends the first indication information according to at least one of the following granularities:

[0132] Service area;

[0133] Service cell group;

[0134] Synchronization information block SSB frequency;

[0135] SSB frequency group;

[0136] Physical cell identifier PCI;

[0137] PCI group;

[0138] Measurement Object;

[0139] measurement target group;

[0140] beam;

[0141] Beam group.

[0142] In this embodiment, the network side device may send according to different granularities when executing step S301 (sending the first reference signal) or executing step S303 (sending the first indication information). The serving cell refers to the cell currently accessed by the UE. For example, if the cell currently accessed by the UE is a secondary cell Scell, when the network side device sends the first reference signal or the first indication information, it may be sent according to the granularity of the Scell ​​(to all user equipment accessing the Scell), or according to the granularity of the Scell ​​group to which the UE belongs (to all user equipment accessing the Scell ​​group). Alternatively, the network side device may also send the first reference signal or the first indication information according to the frequency configured by the SSB, or the frequency group configured by the SSB. Alternatively, the SSB frequency and the serving cell are combined as a granularity, that is, the SSB frequency and PCI are used as granularity, and the first reference signal or the first indication information is sent to all user equipment in the cell corresponding to the frequency configured by the SSB and the PCI at the same time.

[0143] In a specific implementation, for the above-mentioned step S302, the network-side device sends a first reference signal based on the auxiliary information reported by the user equipment UE, that is, the UE reports the auxiliary information to trigger the network-side device to send the first reference signal. Due to different UE requirements and complex actual conditions, there are multiple ways to report auxiliary information by the UE, and the different transmission modes of the first reference signal of the network-side device will lead to certain differences in the information transmission method proposed in the embodiment of the present application. In an optional embodiment, the sending of the first reference signal based on the auxiliary information reported by the user equipment UE includes at least one of the following:

[0144] The network-side device sends the first reference signal according to the auxiliary information reported by the UE during the period of sending the first reference signal in the first sending period;

[0145] The network-side device transmits the first reference signal according to a second transmission period, and after transmitting a first number of times, suspends transmitting the first reference signal until a first time passes or according to the auxiliary information reported by the UE, and then resumes transmitting the first reference signal;

[0146] The network-side device gradually extends a transmission period of the first reference signal until the length of the transmission period reaches a period threshold, and the network-side device suspends transmission of the first reference signal until a certain time passes or the network-side device resumes transmission of the first reference signal based on the auxiliary information reported by the UE.

[0147] 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, maintains the maximum transmission period to send the first reference signal, until the transmission period of the first reference signal is changed according to the auxiliary information reported by the UE or the first indication information of the network side device, and continues to send the first reference signal according to the new period.

[0148] The following implementation manner further illustrates the information transmission method involved in step S302 based on the above embodiment.

[0149] Implementation method 5:

[0150] This embodiment describes the situation where the network-side device executes step S302. The network-side device does not actively send the first reference signal until a UE reports auxiliary information, triggering the network-side device to send 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 send the first reference signal, or step 403 can be executed to send a transmission indication of the first reference signal (first indication information) and then send the first reference signal.

[0151] Implementation method 6:

[0152] This embodiment describes that during the period when the network side device sends the first reference signal in the first sending period, step S302 (sending the first reference signal according to the auxiliary information reported by the UE) is performed.

[0153] Specifically, during the period when the network side device sends the first reference signal with the first sending period, if the length of the first sending period can meet the synchronization, measurement and other requirements of all UEs, the first reference signal continues to be sent according to the first sending period. If some UEs are unable to perform synchronization or measurement and other actions with the first sending period, auxiliary information is reported, thereby triggering the network side device to send an additional first reference signal (i.e., execute step S301, send the first reference signal, or execute step 403, send a sending indication of the first reference signal (first indication information), and then send the first reference signal).

[0154] Implementation method 7:

[0155] This embodiment describes that the network-side device transmits the first reference signal according to the second transmission period. After transmitting the first number, the network-side device suspends transmission of the first reference signal until a UE reports auxiliary information, triggering the network-side device to transmit the first reference signal (performing step 402). Based on the auxiliary information reported by the UE, the network-side device continues to transmit the first reference signal (retransmitting the first reference signal with the second transmission period until the first number is reached again). Specifically, the UE reports auxiliary information, triggering the network-side device to transmit the first reference signal, executing step 401 to transmit the first reference signal, or executing step 403 to transmit a transmission indication (first indication information) of the first reference signal, and then transmitting the first reference signal.

[0156] Implementation method 8:

[0157] 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. The network-side device suspends transmission of the first reference signal until a UE reports auxiliary information, triggering the network-side device to transmit the first reference signal (perform step 402). Based on the auxiliary information reported by the UE, the network-side device continues to transmit the first reference signal (retransmitting the first reference signal with gradually extended transmission periods until the length of the transmission period reaches the period threshold). Specifically, the UE reports auxiliary information, triggering the network-side device to transmit the first reference signal, executes step 401 to transmit the first reference signal, or executes step 403 to transmit a transmission indication (first indication information) of the first reference signal, and then transmits the first reference signal.

[0158] Implementation method 9:

[0159] 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, maintains the maximum transmission period to send the first reference signal, until a UE reports auxiliary information, triggering the network side device to send the first reference signal (execute step 402), and changes the transmission period of the first reference signal according to the auxiliary information reported by the UE, and continues to send the first reference signal according to the new transmission period. If the first reference signal is always sent with a larger transmission period, some UEs in the cell may not be able to maintain the synchronization state, and will report auxiliary information or request information to request the network side device to change to a smaller transmission period. This smaller transmission period can be indicated by the UE, or determined by the network side device according to pre-configured information, or it can be determined based on information of multiple UEs. In this embodiment of the present application, the UE reports auxiliary information to the network side device, which can also be expressed as sending request information to the network side device.

[0160] Specifically, the UE reports auxiliary information (the auxiliary information may include the sending period of the first reference signal expected by the UE), triggers the network side device to send the first reference signal, executes step 401, sends the first reference signal, or, executes step 403, sends the first indication information, which may include: the updated first sending mode (the sending period of the first reference signal) or the sending indication of the first reference signal, and then sends the first reference signal.

[0161] In the related art, the network side device sends a reference signal to each UE at a fixed period for synchronization. However, in actual applications, the method of sending a reference signal at a fixed period does not take into account the actual needs of the UE, which is not conducive to network energy saving. In order to solve the above problem, the embodiment of the present application proposes that when the UE has actual needs, the UE actively reports auxiliary information to the network side device, so that the network side device sends a first reference signal or a first indication information (to indicate the sending or suspension of sending the first reference signal or update the sending period of the first reference signal) based on the received auxiliary information, thereby realizing the on-demand sending of the reference signal and achieving the purpose of network energy saving. The following embodiment specifically describes the auxiliary information reported by the UE.

[0162] In an optional embodiment, the auxiliary information reported by the UE includes at least one of the following:

[0163] synchronization capability of the UE;

[0164] measurement information of the UE;

[0165] second indication information, where the second indication information is used to trigger the network-side device to send the first reference signal;

[0166] synchronization status information of the UE;

[0167] Quasi Co-Location (QCL) information;

[0168] a transmission mode of the first reference signal expected by the UE;

[0169] Decoding information of the UE;

[0170] Energy saving information of the UE.

[0171] Optionally, the auxiliary information reported by the UE may include 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 instruct the network-side device to send the first reference signal. The auxiliary information reported by the UE may also include the first transmission mode expected by the UE, such as an SSB pattern, including information such as the transmission period of the first reference signal and the location of candidate transmission resources.

[0172] Among them, the auxiliary information reported by the UE includes the transmission mode of the first reference signal expected by the UE. Exemplarily, in the above-mentioned embodiment 9, 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 maintains the maximum transmission period to send the first reference signal until a UE reports auxiliary information (the transmission mode of the first reference signal expected by the UE), triggering the network side device to send the first reference signal (execute step 402), and according to the auxiliary information reported by the UE, changes the transmission period of the first reference signal, and continues to send the first reference signal according to the new transmission period.

[0173] Optionally, a minimum or maximum transmission period is determined based on auxiliary information reported by different UEs, so that the first reference signal is sent according to the transmission period. The minimum or maximum transmission period is predefined by the protocol, preconfigured by a network device, configured by the network, indicated by a network device, or determined based on auxiliary information reported by the UE.

[0174] In an optional embodiment, the synchronization capability of the UE includes at least one of the following:

[0175] a maximum transmission period or a maximum transmission interval of the first reference signal supported by maintaining the synchronization state;

[0176] Synchronous signal processing time;

[0177] Synchronization signal type.

[0178] In a specific implementation, the UE may report its own synchronization capability as auxiliary information to the network-side device, so that the network-side device determines whether to send the first reference signal to the UE based on the synchronization capability of the UE. The maximum transmission period or the maximum transmission interval indicates that if the UE still does not receive the first reference signal after exceeding the maximum transmission period or the maximum transmission interval, it is difficult for the UE to maintain the synchronization state. The synchronization signal processing time indicates the processing time of the first reference signal by the UE. The synchronization signal type indicates whether the UE supports the synchronization signal type of the first reference signal based on satellite transmission, the synchronization signal type sent by the base station, or both. In this embodiment, the network-side device can determine the final reference signal transmission period or whether the current reference signal transmission mode has exceeded the maximum transmission period or the maximum transmission interval of the UE based on the auxiliary information reported by the UE. If not, the first reference signal will not be sent or the current transmission period will not be changed. If it exceeds the maximum transmission period or the maximum transmission interval, the first reference signal will be sent or a smaller transmission period that meets the UE's requirements will be selected.

[0179] In an optional embodiment, the measurement information of the UE includes at least one of the following:

[0180] Measurement object; the measurement object includes at least one of the following: DMRS, CSI-RS, SSB, TRS, PTRS;

[0181] The measurement result includes at least one of the following: reference signal received power RSRP, received signal strength indicator RSSI, reference signal received quality RSRQ, and signal to interference plus noise ratio SINR.

[0182] In a specific implementation, the UE may report its own measurement objects and measurement results as auxiliary information to the network side device, so that the network side device determines whether to send the first reference signal or the first indication information to the UE based on the measurement results of the UE. Optionally, when any measurement result of any of the above-mentioned measurement objects of the UE is less than or equal to a preset threshold value (which may indicate that the current synchronization state of the UE is poor, close to being out of sync, and needs to be synchronized using the first reference signal), the UE reports the auxiliary information to the network side device, thereby triggering the network side device to send the first reference signal for synchronization; or, when any measurement result of any of the above-mentioned measurement objects is greater than a preset threshold value (indicating that the current synchronization state of the UE is high and does not need to be synchronized using the first reference signal temporarily), the UE reports the auxiliary information to the network side device, thereby triggering the network side device to send the first indication information to indicate to suspend the sending of the first reference signal.

[0183] In an optional embodiment, the synchronization status information of the UE includes at least one of the following:

[0184] a transmission period of the first reference signal expected by the UE;

[0185] the number of transmissions or repetitions of the first reference signal expected by the UE;

[0186] Synchronization status;

[0187] The latest time at which the UE expects to receive the first reference signal;

[0188] The offset value of the cyclic prefix CP.

[0189] In a specific implementation, the UE may report its own synchronization status information as auxiliary information to the network device, so that the network device can determine whether to send the first reference signal or the first indication information to the UE based on the synchronization status of the UE. For example, when the UE believes that the current transmission period cannot meet its own synchronization requirements, the UE may report the transmission period of the first reference signal desired by the UE (for example, a period smaller than the current transmission period) to the network device as auxiliary information, thereby requesting the network device to send the first reference signal to it according to the period desired by the UE. Optionally, the UE may report the number of transmissions or repetitions of the first reference signal desired by the UE to the network device as auxiliary information, so that the network device updates the transmission mode of the first reference signal based on the transmission number or repetition number, and sends the first reference signal in the updated transmission mode. Optionally, the UE may report its own synchronization status (for example, whether the UE is currently in a downlink out-of-sync state) to the network device. The synchronization status indicates whether the UE is in a synchronized state and may also include information such as the UE's timing offset, frequency offset, and clock synchronization deviation. The magnitude and level of these information values ​​can also be used to measure the synchronization status of the UE. For example, if the synchronization deviation value is too large, it indicates that the current UE is in a downlink out-of-sync state or is close to an out-of-sync state. The network-side device may send a first reference signal based on the reported auxiliary information, or send a transmission indication including the first reference signal and include it in the first indication information. Optionally, the UE may report the latest time (e.g., time position or time offset) for receiving 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.

[0190] In an optional embodiment, the QCL information includes at least one of the following:

[0191] SSB indexindex;

[0192] Reference signal information RS info.

[0193] The QCL information can be used by the network-side device to determine the beam direction of the first reference signal. In specific implementations, the UE can report the QCL information as auxiliary information to the network-side device, so that the network-side device can send the first reference signal in a specific beam direction to the UE based on the QCL information. Optionally, the QCL information can include an SSB index, which represents a specific SSB signal in the SSB set. The QCL information can also include RS info, which is used to indicate the corresponding SSB index.

[0194] In an optional embodiment, the UE decoding information includes at least one of the following:

[0195] Decoding success rate;

[0196] Decoding failure rate;

[0197] ACK rate;

[0198] NACK rate;

[0199] Number of ACKs;

[0200] Number of NACKs.

[0201] Optionally, the network device sends data to the UE, and the UE decodes the received data. When the UE's decoding success rate is low, it indicates that the UE may need to synchronize to adjust the synchronization state to improve the decoding success rate. The UE reports its own decoding information as auxiliary information to the network device. The network device obtains the current UE's decoding success rate based on the UE's decoding information. If the UE's current decoding success rate is not high, the network device sends a first reference signal or first indication information to the UE.

[0202] In an optional embodiment, the energy saving information of the UE includes at least one of the following:

[0203] Energy efficiency rating;

[0204] Battery level or remaining battery level;

[0205] Discontinuous reception CDRX information in connected state.

[0206] In a specific implementation, the UE may report its own energy-saving information as auxiliary information to the network-side device, so that the network-side device determines whether to send the first reference signal or the first indication information to the UE based on the energy-saving information of the UE. For example, if the energy-saving level of the UE is high, the network-side device sends the first reference signal to the UE with a longer transmission period; if the energy-saving level of the UE is low, the network-side device sends the first reference signal to the UE with a shorter transmission period.

[0207] In an optional embodiment, the auxiliary information reported by the UE is transmitted through at least one of the following:

[0208] Physical uplink control channel PUCCH;

[0209] Physical uplink shared channel PUSCH;

[0210] Wake-up signal WUS.

[0211] In a specific implementation, the auxiliary information reported by the UE can be carried by the above-mentioned signaling. Exemplarily, the auxiliary information can be reported by PUCCH signaling as a new type of uplink control information (UCI). Alternatively, it can be carried on the 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 indicate to the network side device that the first reference signal needs to be sent or the transmission period of the first reference signal needs to be changed.

[0212] In an optional embodiment, the priority of the auxiliary information reported by the UE satisfies at least one of the following:

[0213] The priority of the auxiliary information transmitted via PUCCH is the target priority;

[0214] The priority of auxiliary information transmitted via PUSCH is determined according to the priority of PUSCH;

[0215] The priority of the auxiliary information reported by the UE is determined according to information carried in the auxiliary information reported by the UE.

[0216] In specific implementation, for different auxiliary information reported by different UEs, the priority of the auxiliary information can be determined based on the priority of the transmission signaling that carries the auxiliary information, or the priority of the auxiliary information itself can be determined based on the information carried in the auxiliary information. For example, if the PUCCH signaling is set to a high priority, then the signaling transmitted through the PUCCH will be determined to be a high priority accordingly. Alternatively, the priority of is set to A, and the priority of the measurement information is set to B, A takes precedence over B, then the auxiliary information carrying the indication information that directly triggers the sending of the first reference signal has a higher priority than the auxiliary information carrying the measurement information. Optionally, the priority of the reporting signaling of the auxiliary information (such as PUCCH, PUSCH) can be predefined by the protocol, preconfigured by the network-side device, or determined by the network-side device configuration.

[0217] In an optional embodiment, the auxiliary information may be a newly added UCI type and reported by PUCCH signaling. The UCI type priority satisfies at least one of the following:

[0218] HARQ-ACK > auxiliary information reported by UE > Scheduling Request (SR) > CSI with higher priority > CSI with lower priority;

[0219] UE auxiliary information > HARQ-ACK > SR > CSI with higher priority > CSI with lower priority;

[0220] HARQ-ACK>SR>UE auxiliary information>CSI with higher priority>CSI with lower priority;

[0221] HARQ-ACK>SR>CSI with higher priority>UE auxiliary information>CSI with lower priority;

[0222] HARQ-ACK>SR>CSI with higher priority>CSI with lower priority>UE auxiliary information.

[0223] Optionally, if the UE auxiliary information is divided into high priority and low priority, the priority positions of the high priority UE auxiliary information and the low priority auxiliary information may be different. For example, high priority auxiliary information > CSI with higher priority, while low priority auxiliary information <CSI with lower priority。

[0224] In an optional embodiment, the network-side device sends the first reference signal or sends an instruction to send the first reference signal when at least one of the following conditions is met:

[0225] The measurement results corresponding to the measurement objects reported by all or at least part of the UEs that report the auxiliary information are less than a threshold;

[0226] The UE requests the network side device to send the first reference signal or change a sending period of the first reference signal;

[0227] UEs whose number is greater than N or whose proportion is greater than Q request the network side device to send the first reference signal or change the sending period of the first reference signal, where N is greater than 0 and Q is greater than 0 and less than 1;

[0228] The UE that requested the network-side device to send the first reference signal has downlink data arriving. Optionally, when downlink data arrives for the UE, it indicates that the network-side device will send data to the UE and requires the UE to maintain a good synchronization state. Therefore, in this case, the network-side device sends the first reference signal or sends an indication of sending the first reference signal, so that the UE performs a synchronization operation.

[0229] 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 a timing offset value, a frequency offset value, and a clock synchronization deviation value.

[0230] In an optional embodiment, the network-side device suspends sending the first reference signal or sends an indication of suspending sending the first reference signal when at least one of the following conditions is met:

[0231] The UE that reports the auxiliary information instructs to stop receiving the first reference signal;

[0232] The UE reporting the auxiliary information indicates CDRX information or state transition information;

[0233] The measurement results corresponding to the measurement objects reported by all or at least some of the UEs that report the auxiliary information are greater than a threshold;

[0234] The UE that reports all or at least part of the auxiliary information indicates that the first reference signal is no longer needed;

[0235] The UE indication that all or at least part of the reporting of the assistance information may rely on synchronization with other cells;

[0236] The network-side device no longer receives the auxiliary information reported by the UE;

[0237] The sending time window of the first reference signal ends;

[0238] Arriving at the end sending resource position of the first reference signal;

[0239] After sending T times at the maximum sending period, T is greater than 0. Exemplarily, referring to Embodiment 3-1 or Embodiment 3-2 above, the network-side device gradually extends the sending period of the first reference signal until the length of the sending period reaches a period threshold, and the network-side device suspends sending the first reference signal or sends an indication of suspending sending the first reference signal.

[0240] It should be noted that different sending times of the first reference signal will result in different energy consumption of the network side device or UE. The following embodiment further illustrates the sending time of the first reference signal by the network side device.

[0241] In an optional embodiment, the sending time of the first reference signal sent by the network side device is determined according to at least one of the following:

[0242] a reference sending time of the first reference signal;

[0243] Time offset.

[0244] In this embodiment, the sending time of the first reference signal sent by the network side device is the start time of sending the first reference signal. Optionally, the network side device starts sending the first reference signal at the reference point (that is, the reference sending time) + time offset, which is mainly applicable to the following situations:

[0245] In case 1, after receiving the auxiliary information reported by the UE, the network device sends the first reference signal as soon as possible, regardless of the transmission time of the first reference signals determined by other UEs. In this case, the first reference signal is similar to UE-specific. However, if multiple UEs request the first reference signal at different times (reporting auxiliary information to the network device), the network device needs to send multiple sets of first reference signals, which is not conducive to energy saving for the network device.

[0246] Case 2: After receiving the auxiliary information reported by the UE, the network side device determines the starting transmission time (i.e., the transmission time) of a 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, so as to unify the UE's understanding of the starting transmission time of the first reference signal.

[0247] Case 3: The network-side device determines a start transmission time (ie, transmission time) of a first reference signal. The time offset indicated for different UEs may be different, so as to unify the understanding of the transmission time of the first reference signal.

[0248] Case 4: The sending resource position at which the network-side device sends the first reference signal belongs to a candidate sending resource position of the pre-configured position.

[0249] The network-side device does not start sending the first reference signal at the reference point + time offset. This is applicable to the following situations:

[0250] Case 5: The time offset is indicated by the UE and represents a desired first reference signal transmission resource location. However, to maximize power conservation, the network device determines an appropriate first reference signal transmission resource location based on the requests (reported auxiliary information) of multiple UEs. Therefore, for some UEs, the network device may not transmit the first reference signal at the reference point + time offset location. In this case, these UEs need to search for the first reference signal in the time domain from the reference point + time offset location, resulting in a certain amount of power waste.

[0251] In case 6, the network device always transmits the first reference signal at a preconfigured candidate transmission resource location for the first reference signal. The reference point + time offset determines the specific candidate transmission resource location at which the network device transmits the first reference signal. For example, the network device transmits the first reference signal at the next candidate transmission resource location after the reference point + time offset that meets a certain processing time. Compared to case 5, the transmission method in case 6 can further reduce UE power consumption.

[0252] In an optional embodiment, the reference sending time of the first reference signal is determined according to at least one of the following:

[0253] The time when the network-side device sends the first indication information;

[0254] The time when the UE reports the auxiliary information;

[0255] The candidate sending time is predefined by the protocol or preconfigured by the network side device.

[0256] In specific implementation, there are two types of reference sending times (sending positions) of the first reference signal. One is flexible sending, that is, the reference sending time is determined according to the time when the network side device sends the first indication information; or, the reference sending time is determined according to the time when the UE reports the auxiliary information. The other is to send at a preconfigured time or resource position, that is, the protocol predefines or the network side device preconfigures a candidate sending time or candidate sending resource position for the first reference signal. Exemplarily, a bitmap is used to indicate, or a starting time or resource position is determined by DFN / SFN index+symbol index, and then repeated according to a preconfigured period, that is, the candidate sending time or candidate sending resource position of the first reference signal. When the first reference signal is sent, it is always sent at the candidate sending time or candidate sending resource position.

[0257] In an optional embodiment, the time offset is determined according to at least one of the following:

[0258] processing time of the UE processing the first indication information;

[0259] The processing time of the network side device processing the HARQ-ACK sent by the UE;

[0260] Preparation time for the network side device to send the first reference signal;

[0261] The processing time of the network side device for processing the auxiliary information reported by the UE;

[0262] a first time, wherein the first time represents an additional processing time predefined by the protocol;

[0263] a second time, where the second time represents a time reserved for uniformly sending the first reference signal;

[0264] Instructed by the UE;

[0265] Instructed by the network side device;

[0266] Predefined by the protocol;

[0267] Pre-configured by the network side device.

[0268] In the embodiments of the present application, preparation time can be expressed as processing time. For example, 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 embodiment, the timing for the network-side device to send the first reference signal satisfies one of the following four solutions.

[0269] Solution 1: Based on the above situation 1, the network side device triggers the transmission of the first reference signal after receiving the auxiliary information reported by any UE, without considering the transmission time of the first reference signal determined by other UEs. In this case, the transmission time (i.e., the starting transmission time) of the network side device to send the first reference signal is set to n1+k1, the reference transmission time (the indication time of the network side device to send the first reference signal, i.e., the time when the network side device sends the first indication information) is n1, and the time offset is k1. In solution 1, k1 includes at least one of the following:

[0270] The processing time of the UE for processing the first indication information;

[0271] 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 sending indication of the first reference signal) and then sends the first reference signal, considering that the network side device sends the first indication information to the UE, the UE will send HARQ-ACK to the network side device after successfully receiving and understanding it, so k1 includes the processing time of the network side device for the HARQ-ACK.

[0272] Preparation time for the network side device to send the first reference signal;

[0273] First time.

[0274] Optionally, k1 may be indicated by a network-side device, predefined by a protocol, or preconfigured by a network-side device.

[0275] Solution 2: Based on the above situation 1, the network side device triggers the transmission of the first reference signal after receiving the auxiliary information reported by any UE, without considering the transmission time of the first reference signal determined with 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, the transmission time (i.e., the starting transmission time) of the first reference signal sent by the network side device is set to n2+k2, the reference transmission time (i.e., the time when the UE reports the auxiliary information) is n2, and the time offset is k2. In solution 2, k2 includes at least one of the following:

[0276] The processing time of the network side device for processing the auxiliary information reported by the UE;

[0277] Preparation time for the network side device to send the first reference signal;

[0278] First time.

[0279] Optionally, k2 may be indicated by the UE, predefined by the protocol, or preconfigured by a network-side device.

[0280] It should be noted that in this case, the network-side device may also send the first indication information, for example, only instructing the terminal currently sending the auxiliary information to send information about the first reference signal. In this case, the network-side sends the first reference signal at a sending time n2+k2, or it may be n1+k1 (as defined in Solution 1).

[0281] Solution 3: Based on the above situation 2, after receiving the auxiliary information reported by multiple UEs, the network side device determines a unified starting transmission time (i.e., transmission time) of the first reference signal according to the auxiliary information reported by different UEs in order to save energy. Otherwise, the UE may blindly search for the first reference signal in advance, resulting in waste of 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, the transmission time (i.e., the starting transmission time) of the first reference signal sent by the network measurement device is set to n3+k3, the reference transmission time (i.e., the time when the UE reports the auxiliary information) is n3, and the time offset is k3. In solution 3, k3 includes at least one of the following:

[0282] processing time of the UE processing the first indication information;

[0283] Preparation time for the network side device to send the first reference signal;

[0284] the first time;

[0285] the second time.

[0286] Optionally, k3 is indicated by the UE, indicated by the network side device, predefined by the protocol, or preconfigured by the network side device.

[0287] Solution 4: Based on the above situation 2, after receiving auxiliary information reported by multiple UEs, the network-side device determines a unified starting transmission time (i.e., transmission time) of the first reference signal based on the auxiliary information reported by different UEs in order to save energy. Otherwise, the UE may blindly search for the first reference signal in advance, resulting in power consumption waste. In this case, the transmission time (i.e., the starting transmission time) of the first reference signal sent by the network-side device is set to n4+k4, the reference transmission time (the time when the network-side device sends the first indication information) is n4, and the time offset is k4.

[0288] In scenario 4, k4 contains at least one of the following:

[0289] The processing time of the network side device for processing the auxiliary information reported by the UE;

[0290] processing time of the UE processing the first indication information;

[0291] 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 sending indication of the first reference signal) and then sends the first reference signal, considering that the network side device sends the first indication information to the UE, the UE will send HARQ-ACK to the network side device after successfully receiving and understanding it, so k4 includes the processing time of the network side device for HARQ-ACK.

[0292] Preparation time for the network side device to send the first reference signal;

[0293] First time;

[0294] Second time.

[0295] Optionally, k4 is indicated by the UE, indicated by the network side device, predefined by the protocol, or preconfigured by the network side device.

[0296] A second aspect of an embodiment of the present application provides an information transmission method, which is applied to a user equipment (UE). Referring to FIG. 4 , FIG. 4 shows a flowchart of another information transmission method. As shown in FIG. 4 , the information transmission method includes:

[0297] The user equipment UE performs at least one of the following:

[0298] Step S401: reporting auxiliary information to a network-side device, where the auxiliary information is used to trigger the network-side device to send a first reference signal;

[0299] Step S402: determining whether to receive a first reference signal sent by the network-side device according to the first information;

[0300] Step S403: After receiving 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:

[0301] an indication of sending the first reference signal;

[0302] an indication of suspending transmission of the first reference signal;

[0303] a transmission mode of the first reference signal.

[0304] In the related art, the network side equipment 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 take into account the actual needs of the UE, which is not conducive to network energy saving. In order to solve the above problem, the embodiment of the present application proposes that the UE can, according to its own actual situation, when determining the need to synchronize with the network side equipment or perform measurements and other actions, execute step S401, and the UE reports auxiliary information to the network side equipment, thereby triggering the network side equipment to send a first reference signal or a first indication information (to indicate the sending / pause of sending the first reference signal or update the sending period of the first reference signal), thereby realizing the on-demand sending of the reference signal and achieving the purpose of energy saving of the network side equipment.

[0305] Furthermore, after receiving the auxiliary information reported by the UE, the network-side device may send first indication information (including an indication of sending the first reference signal), thereby causing the UE to execute step S403. Specifically, the UE returns a HARQ-ACK message to the network-side device based on 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 may send first indication information related to the first reference signal to indicate the sending of the first reference signal, suspend the sending of the first reference signal, and update the sending mode of the first reference signal, thereby flexibly controlling the sending of the reference signal.

[0306] In an optional embodiment, within a predefined or network-side preconfigured period of time, or during a first reference signal transmission behavior or transmission period of a network-side device, the UE should / expects / assumes that it does not need to receive the first reference signal again after receiving it, or should / expects / assumes that it receives the first reference signal only once. The first reference signal transmission behavior of the network-side device includes: transmitting one or more first reference signals. Exemplarily, the first reference signal transmission behavior of the network-side device corresponds to one first reference signal transmission in a certain transmission mode triggered by the network-side device or the UE.

[0307] There is no specific order between the above steps S401-S403, and they can be set according to actual needs.

[0308] In an optional embodiment, the UE receiving the first reference signal sent by the network side device includes:

[0309] The UE determines a sending time of the first reference signal according to at least one of the following: a reference sending time of the first reference signal; a time offset;

[0310] The UE receives or measures the first reference signal at a time when the first reference signal is sent.

[0311] In this embodiment, after the UE performs step S401 and reports auxiliary information to the network device to trigger the network device to transmit a first reference signal, the UE needs to determine the transmission time of the first reference signal, so as to receive the first reference signal transmitted by the network device at the transmission time. In one possibility, the UE can determine the transmission time based on the reference transmission time and the time offset. The specific method for determining the transmission time is described in the above embodiment for the transmission time and will not be repeated in this embodiment. In another possibility, the UE can directly determine the transmission time based on the transmission period or transmission mode of the first reference signal indicated by the network device, pre-configured by the network device, or pre-defined by the protocol. In this embodiment of the application, the UE reports auxiliary information to the network device to trigger the transmission of the first reference signal, searches for the first reference signal at the determined transmission time, and receives the first reference signal, thereby implementing on-demand transmission of the first reference signal. In the context of the network device transmitting the first reference signal at an excessively long period or time interval for energy saving, or not transmitting the reference signal at all, the on-demand transmission of the first reference signal can avoid affecting the UE's synchronization, measurement, phase tracking, demodulation, etc.

[0312] In an optional embodiment, the reference sending time of the first reference signal is determined according to at least one of the following:

[0313] The time when the network-side device sends the first indication information;

[0314] The time when the UE reports the auxiliary information;

[0315] The candidate sending time is predefined by the protocol or preconfigured by the network side device.

[0316] In an optional embodiment, the time offset is determined according to at least one of the following:

[0317] processing time of the UE processing the first indication information;

[0318] The processing time of the network side device processing the HARQ-ACK sent by the UE;

[0319] Preparation time for the network side device to send the first reference signal;

[0320] The processing time of the network side device for processing the auxiliary information reported by the UE;

[0321] a first time, wherein the first time represents an additional processing time predefined by the protocol;

[0322] a second time, where the second time represents a time reserved for unified SSB transmission;

[0323] Instructed by the UE;

[0324] Instructed by the network side device;

[0325] Predefined by the protocol;

[0326] Pre-configured by the network side device.

[0327] It is understood that the time offset is a value greater than or equal to 0. The time unit may be a radio frame, a subframe, a time slot, a mini-time slot, a second, a millisecond, etc.

[0328] In an optional embodiment, the UE determines, according to the first information, whether to receive the first reference signal sent by the network side device, including:

[0329] The UE performs a first action according to the first information, where the first action includes at least one of the following:

[0330] receiving the first reference signal;

[0331] Sending a first transmission object, where the first transmission object includes at least one of the following: a PUCCH, a PUSCH, a physical random access channel PRACH, and a sounding reference signal SRS;

[0332] A first receiving object is received, where the first receiving object includes at least one of the following: a physical downlink control channel PDCCH, a physical downlink shared channel PDSCH, a CSI-RS, a TRS, and a PTRS.

[0333] In this embodiment, when the UE is receiving the first reference signal sent by the network side device, it is easy for the transmission position of the first reference signal to at least partially overlap with the first transmission object or the first reception object, and other conflicts may 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 half-duplex reasons, if there is a conflict with UL transmission, it is necessary to choose whether to receive the first reference signal or perform uplink transmission (send the first transmission object), and if there is a conflict with DL reception, based on reliability, the UE may need to choose whether to receive the first reference signal or perform other DL receptions (receive the first reception object), so it is necessary to determine the priority execution behavior based on the conditions or first information satisfied by the current actual situation.

[0334] 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; and the UE performs the first behavior according to the first information, including at least one of the following:

[0335] The UE preferentially receives the first reference signal according to the first target information;

[0336] When the first condition is met, the UE preferentially receives the first reference signal, where the first condition includes at least one of the following:

[0337] The UE has requested the first reference signal from the network-side device. It can be understood that since the sending behavior is requested by the UE, the UE preferentially receives the first reference signal.

[0338] The first reference signal is sent by the network side device for the first time;

[0339] The UE's measurement result of 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 synchronization, measurement, demodulation, phase tracking, etc., so the UE preferentially receives the first reference signal.

[0340] The UE is no longer synchronized;

[0341] The UE is close to being out of sync; exemplarily, if the UE is no longer synchronized or is close to being out of sync, the first condition is met and the first reference signal is received first; if the UE synchronization state is better, receiving the first reference signal is a low priority, and priority is given to receiving the first receiving object or sending the first sending object.

[0342] 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;

[0343] A sending period of the first reference signal is greater than a period threshold;

[0344] 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 a synchronization requirement, a measurement requirement or a state of the UE.

[0345] The sending time of the first reference signal at least partially overlaps with the sending time of the first sending object;

[0346] The sending time of the first reference signal at least partially overlaps with the sending time of the first receiving object;

[0347] The first sending object or the first receiving object is control information;

[0348] The first sending object or the first receiving object includes control information;

[0349] The uplink UL priority is greater than or equal to the first threshold, or less than or equal to the second threshold; it can be understood that whether to preferentially receive the first reference signal is determined according to the preconfigured priority.

[0350] The priority of the downlink DL is greater than or equal to the third threshold, or less than or equal to the fourth threshold. It can be understood that whether to preferentially receive the first reference signal is determined according to the preconfigured priority.

[0351] The sending time of the first reference signal at least partially overlaps with the sending time of the first sending object that meets the third condition;

[0352] The sending time of the first reference signal at least partially overlaps with the sending time of the first receiving object that meets the third condition;

[0353] The third condition includes at least one of the following:

[0354] The first sending destination or the first receiving destination is located in a Scell;

[0355] The first sending object or the first receiving object is located in a Pcell;

[0356] The first sending object or the first receiving object is an initial transmission;

[0357] The first sent object or the first received object is a retransmission;

[0358] The first target information includes at least one of the following:

[0359] Whether the transmission resource of the first transmission object or the first reception object is a dynamically granted DG; illustratively, when the transmission resource of the first transmission object or the first reception object is a DG, the first transmission object is preferentially transmitted or the first reception object is preferentially received. It is understood that in this case, the dynamically scheduled resource is considered to have a higher priority for transmission and reception. Of course, if pre-configured or determined by the terminal to have a lower priority for transmission and reception on the dynamically scheduled resource, the first reference signal is preferentially received.

[0360] Whether the transmission resource of the first sending object or the first receiving object is a configuration authorization CG; illustratively, when the transmission resource of the first sending object or the first receiving object is a CG, receiving the first reference signal takes precedence over sending the first sending object or receiving the first receiving object. It can be understood that at this time, it is considered that the sending and receiving priority on the statically scheduled resources is lower. Of course, if the pre-configuration or terminal determines that the sending and receiving priority on the statically scheduled resources is higher, the first sending object or the first receiving object is sent first.

[0361] Whether the first reference signal is triggered by the UE; illustratively, if the first reference signal is triggered by the UE (the UE reports auxiliary information, triggering the network side device to send the first reference signal), the first reference signal is received preferentially.

[0362] The purpose of receiving the first reference signal; illustratively, if the purpose of receiving the first reference signal is synchronization (or activation, de-measurement), the first reference signal is received first; if the purpose of receiving the first reference signal is measurement, the first reference signal is not received first.

[0365] The transmission mode of the first reference signal. Exemplarily, if the transmission mode of the first reference signal is a transmission mode of repeated transmission, the first reference signal is not received preferentially; if the transmission mode is a transmission mode of only sending once, the first reference signal is received preferentially.

[0368] The first receiving object is at least one of the following: PDSCH; CSI-RS; PDCCH.

[0369] In an optional embodiment, the first information on which the UE performs the first behavior includes at least a second condition and second target information; and the UE performs the first behavior according to the first information, including at least one of the following:

[0370] The UE preferentially sends the priority of the first sending object or preferentially receives the first receiving object according to the second target information;

[0371] When the second condition is met, the UE preferentially sends the priority of the first sending object or preferentially receives the first receiving object, where the second condition includes at least one of the following:

[0372] The UE does not request the first reference signal from the network side device; it can be understood that at this time the UE may not need to receive the first reference signal to perform synchronization, measurement and other actions.

[0373] The first reference signal is not transmitted for the first time by the network device. For example, when the first reference signal is an SSB and the currently received SSB belongs to the Lth SSB period, where L>1, it is understood that the UE may have already received the first reference signal. That is, within a period of time or a first reference signal transmission behavior or transmission period of the network device, the UE should / expects / assumes that it does not need to receive the first reference signal again after having received it, or should / expects / assumes that it only receives the first reference signal once.

[0374] A measurement result of the UE on the first object is greater than a threshold;

[0375] The UE relies on other cells to achieve synchronization;

[0376] The synchronization state level of the UE is greater than a preset state level;

[0377] A sending period of the first reference signal is less than a period threshold;

[0378] The first reference signal can be received within the first time window or the second time period; it can be understood that the subsequent UE can also receive the first reference signal.

[0379] The sending time of the first reference signal at least partially overlaps with the sending time of the first sending object;

[0380] The sending time of the first reference signal at least partially overlaps with the sending time of the first receiving object;

[0381] The first sending object or the first receiving object is control information; exemplarily, when the first sending object or the first receiving object is control information, sending the first sending object or receiving the first receiving object takes precedence over receiving the first reference signal.

[0382] The first sending object or the first receiving object includes control information;

[0383] The uplink UL priority is less than or equal to the first threshold, or greater than or equal to the second threshold;

[0384] The downlink DL priority is less than or equal to the third threshold, or greater than or equal to the fourth threshold;

[0385] The sending time of the first reference signal at least partially overlaps with the sending time of the first sending object that meets the fourth condition;

[0386] The sending time of the first reference signal at least partially overlaps with the sending time of the first receiving object that meets the fourth condition;

[0387] The fourth condition includes at least one of the following:

[0388] The first sending destination or the first receiving destination is located in a Scell;

[0389] The first sending object or the first receiving object is located on the Pcell. Exemplarily, when the first sending object or the first receiving object is located on the Pcell, sending the first sending object or receiving the first receiving object takes precedence over receiving the first reference signal.

[0390] The first sending object or the first receiving object is an initial transmission; it can be understood that the priority of the initial transmission is higher at this time.

[0391] The first sending object or the first receiving object is a retransmission; it can be understood that the retransmission is considered to have a higher priority at this time because the initial transmission has not been successfully received.

[0392] The second target information includes at least one of the following:

[0393] Whether the transmission resource of the first sending object or the first receiving object is DG; exemplarily, when the first sending object or the first receiving object is DG, sending the first sending object or receiving the first receiving object takes precedence over receiving the first reference signal.

[0394] Whether the transmission resource of the first sending object or the first receiving object is CG;

[0395] whether the first reference signal is triggered by the UE;

[0396] whether the first reference signal can be received within a first time period;

[0397] a purpose of receiving the first reference signal;

[0398] synchronization status information of the UE;

[0399] measurement information of the UE;

[0400] a transmission mode of the first reference signal.

[0401] In this embodiment, different conditions (first condition or second condition) also have different priorities, which may be predefined by a protocol, preconfigured by a network device, configured by a network device, or indicated by a network device. For example, if the UE triggers the network device to send the first reference signal for the first time, the first reference signal is always received first, regardless of any conditions met for uplink transmission or downlink reception.

[0402] The following embodiments are used to illustrate the specific content of the auxiliary information reported by the UE.
