[0148] In some embodiments, the access network device 102-1 can be composed of a centralized unit (CU) and a distributed unit (DU), where the CU can also be called a control unit. The CU-DU structure can be used to split the protocol layer of the access network device, with the functions of some protocol layers centrally controlled by the CU, and the functions of the remaining part or all of the protocol layers distributed in the DU, which is centrally controlled by the CU, but is not limited to this.

[0149] In some embodiments, the network device 102 includes a core network device 102-2. The core network device 102-2 can be a single device, multiple devices, or a group of devices. The network element can be virtual or physical. The core network includes, for example, at least one of an Evolved Packet Core (EPC), a 5G Core Network (5GCN), and a Next Generation Core (NGC).

[0151] It can be understood that the communication system described in the embodiment of the present disclosure is for the purpose of more clearly illustrating the technical solution of the embodiment of the present disclosure, and does not constitute a limitation on the technical solution proposed in the embodiment of the present disclosure. Ordinary technicians in this field can know that with the evolution of the system architecture and the emergence of new business scenarios, the technical solution proposed in the embodiment of the present disclosure is also applicable to similar technical problems.

[0152] The following embodiments of the present disclosure may be applied to the communication system 100 shown in FIG1 , or a portion thereof, but are not limited thereto. The entities shown in FIG1 are illustrative only. The communication system may include all or part of the entities shown in FIG1 , or may include other entities outside of FIG1 . The number and form of the entities are arbitrary, and the entities may be physical or virtual. The connection relationships between the entities are illustrative only. The entities may be connected or disconnected, and the connection may be in any manner, including direct or indirect, wired or wireless.

[0153] The embodiments of the present disclosure can be applied to Long Term Evolution (LTE), LTE-Advanced (LTE-A), LTE-Beyond (LTE-B), SUPER 3G, IMT-Advanced, 4th generation mobile communication system (4G), 5th generation mobile communication system (5G), 5G new radio (NR), future radio access (FRA), new radio access technology (RAT), new radio (NR), new radio access (NX), future generation radio access (FX), Global System for Mobile communications (GSM (registered trademark)), CDMA2000, Ultra Mobile Broadband (UMB), IEEE 802.11 (Wi-Fi (registered trademark)), IEEE 802.16 (WiMAX (registered trademark)), IEEE 802.20, Ultra-WideBand (UWB), Bluetooth (registered trademark), Public Land Mobile Network (PLMN) networks, systems utilizing other communication methods, and next-generation systems based on these.

[0154] In Release 17 (R17), the access network device can send an inactive uplink positioning reference signal configuration to the terminal via a Radio Resource Control (RRC) release message. When the terminal reselects a cell, the terminal releases the uplink positioning reference signal configuration. Uplink positioning reference signals include but are not limited to the Sounding Reference Signal (SRS).

[0155] In Release 18 (R18), the SRS validity area was introduced. When the network device configures SRS for a terminal and configures the SRS validity area, when the terminal reselects to another cell, as long as the other cell is within the validity area, the terminal can continue to transmit SRS.

[0156] For an SRS configured with an SRS validity area, the terminal may decide to suspend SRS transmission or resume SRS transmission according to a spatial relation.

[0157] If network equipment, such as the core network LMF, is unaware that the terminal has suspended SRS transmission, the LMF may request the access network equipment to measure SRS at the wrong time. Due to the suspended SRS transmission, the access network equipment cannot measure SRS. Further, the LMF may trigger the access network equipment to reconfigure SRS for the terminal. However, the terminal may actually resume SRS transmission without the network equipment having to reconfigure SRS.

[0158] In order to inform network devices of the status of SRS transmission, avoid wasting signaling resources, and improve the reliability of uplink positioning and / or uplink and downlink hybrid positioning, the present disclosure provides the following information transmission method, device, and storage medium.

[0159] FIG2A is an interactive diagram of an information transmission method according to an embodiment of the present disclosure. As shown in FIG2A , the present disclosure embodiment relates to an information transmission method, which includes:

[0160] In step S2101 , the terminal 101 sends an indication message to the access network device 102 - 1 via a first message in response to suspending or resuming SRS transmission.

[0161] In some embodiments, the access network device 102 - 1 receives the indication information.

[0162] In some embodiments, suspending SRS transmission may refer to the terminal 101 pausing SRS transmission.

[0163] In some embodiments, resuming SRS transmission may mean that the terminal 101 may resume SRS transmission after suspending SRS transmission based on SRS configuration.

[0164] In some embodiments, the SRS is configured with a valid area.

[0165] In some embodiments, the valid area refers to the valid area of ​​the uplink positioning reference signal configured by the network device 102 for the terminal 101.

[0166] When the terminal switches or reselects in a cell in the valid area, it can continue to use the configured uplink positioning reference signal without the network device having to reconfigure a new uplink positioning reference signal.

[0167] In some embodiments, the indication information is used to indicate suspension or resumption of SRS transmission.

[0168] In some embodiments, the name of the indication information is not limited.

[0169] In some embodiments, the first message may be a Radio Resource Control (RRC) message.

[0170] In some embodiments, the RRC message may include, but is not limited to, any one of the following: terminal positioning assistance information (UE positioning assistance information); terminal assistance information (UE assistance information); RRC reconfiguration complete (RRC ReconfigurationComplete) message.

[0171] In some embodiments, the RRC message may also be a new RRC message defined by the protocol, and the RRC message is used to send indication information.

[0172] In some embodiments, the first message may further include a suspension reason or a resumption reason for SRS transmission.

[0173] In some embodiments, the suspension reason includes but is not limited to any one of the following: the spatial relationship of the SRS does not meet the conditions for sending the SRS; the reference signal associated with the spatial relationship of the SRS cannot meet the measurement requirements.

[0174] In an example, the spatial relationship of the SRS means that the beam direction for transmitting the SRS corresponds to the reference signal associated with the spatial relationship.

[0175] In one example, when the terminal 101 determines that it cannot receive a reference signal associated with the spatial relationship of the SRS, for example, when it cannot receive a synchronization signal block (Synchronization Signal / PBCH Block, SSB) or a positioning reference signal (Positioning Reference Signal, PRS), it can be determined that the spatial relationship of the SRS does not meet the conditions for sending the SRS. The present disclosure does not specifically limit whether the spatial relationship of the SRS does not meet the conditions for sending the SRS.

[0176] In one example, the failure of the reference signal associated with the spatial relationship of the SRS to meet the measurement requirement may include, but is not limited to, the measured reference signal received power (RSRP) being too low or below a preset threshold. The present disclosure does not specifically limit the failure of the reference signal associated with the spatial relationship of the SRS to meet the measurement requirement.

[0177] In some embodiments, the restoration reason includes but is not limited to any one of the following: the spatial relationship of the SRS meets the conditions for sending the SRS; the reference signal associated with the spatial relationship of the SRS meets the measurement requirements.

[0178] In one example, when terminal 101 receives a reference signal associated with the spatial relationship of the SRS, such as an SSB or PRS, it can determine that the spatial relationship of the SRS meets the conditions for sending the SRS. This disclosure does not specifically limit whether the spatial relationship of the SRS meets the conditions for sending the SRS.

[0179] In one example, the reference signal associated with the spatial relationship of the SRS meeting the measurement requirement may include but is not limited to the measured reference signal received power (RSRP) reaching or exceeding a preset threshold. The present disclosure does not specifically limit the reference signal associated with the spatial relationship of the SRS meeting the measurement requirement.

[0180] Step S2102: Terminal 101 sends a request message to the access network device 102-1.

[0181] In some embodiments, the access network device 102 - 1 receives the request message.

[0182] In some embodiments, the terminal 101 may send the request message to the access network device 102 - 1 while suspending SRS transmission.

[0183] In some embodiments, the request message is used to request the access network device 102 - 1 to update the spatial relationship of the SRS.

[0184] In some embodiments, the request message may be sent by the terminal to the access network device 102 - 1 via a second message different from the first message.

[0185] Exemplarily, the second message may be an RRC message.

[0186] In some embodiments, the request message may be sent by the terminal to the access network device 102-1 via a first message, that is, the first message includes the above-mentioned indication information and the request message, thereby saving terminal signaling resources.

[0187] Step S2103: The terminal 101 sends the measurement result to the access network device 102-1.

[0188] In some embodiments, the access network device 102 - 1 receives the measurement result.

[0189] In some embodiments, the measurement results include but are not limited to measurement results of different beams, RSRP, etc.

[0190] In some embodiments, the measurement results may be used by the network device to update the spatial relationship of the SRS.

[0191] In some embodiments, the measurement result may be sent by the terminal to the access network device 102 - 1 via a third message different from the first message.

[0192] Exemplarily, the third message may be an RRC message.

[0193] In some embodiments, the terminal may send the measurement result to the access network device 102-1 via a first message. That is, the first message includes the above-mentioned indication information and the measurement result, thereby saving terminal signaling resources.

[0194] In some embodiments, at least one of indication information, resumption reason or suspension reason, request message and measurement result may be sent via the first message, which is not limited in the present disclosure.

[0195] In step S2104, the access network device 102-1 sends the indication information to the core network device 102-2.

[0196] In some embodiments, the core network device 102 - 2 may receive the indication information.

[0197] In some embodiments, the core network device 102 - 2 may determine a timing to trigger the access network device 102 - 1 to measure the SRS based on the indication information.

[0198] In one example, when the indication information indicates that the SRS transmission is suspended, the core network device 102 - 2 determines that this is not a time to trigger the access network device 102 - 1 to measure the SRS.

[0199] In one example, when the indication information indicates that SRS transmission is resumed, the core network device 102-2 may determine the current time point or any time point before receiving the new indication information as a time point to trigger the access network device 102-1 to measure SRS. The new indication information indicates that SRS transmission is suspended.

[0200] In some embodiments, the access network device 102-1 may send the indication information to the core network device 102-2 via a New Radio Positioning Protocol A (NR Positioning Protocol A, NRPPa) message.

[0201] In some embodiments, the NRPPa message may include but is not limited to any one of the following: a positioning information update message; a transmission reception point information update message.

[0202] In some embodiments, the NRPPa message may be a new NRPPa message agreed upon by the protocol, which is used to send indication information.

[0203] In some embodiments, the NRPPa message may include a suspension reason or a resumption reason of the SRS transmission. The specific contents of the suspension reason and the resumption reason have been introduced in the above step S2101 and will not be repeated here.

[0204] In some embodiments, a new enumeration type may be added to the SRS Transmission Status IE of the positioning information update message, for example, the enumeration types "suspend" and "resume" may be added, corresponding to suspending SRS transmission and resuming SRS transmission, respectively, as shown in Table 1.

[0205] Table 1

[0206] In some embodiments, the SRS Transmission Status IE can be reused. If the terminal 101 sends a suspend or resume indication of the terminal to the access network device 102-1, the access network device 102-1 can carry a cause value in the positioning information update message sent to the core network device 102-2. The cause value can be set to "UE suspend" or "UE resume" respectively. For example, a new IE is added to the positioning information update message. The IE name is "Cause" and is used to indicate the suspension reason or the resume reason, as shown in Table 2, so that the core network device 102-2 can determine the suspension reason or the resume reason of the SRS transmission based on the cause value.

[0207] Table 2

[0208] In some embodiments, the access network device 102-1 may send the request message and / or the measurement result to the core network device 102-2 via an NRPPa message, and the core network device 102-2 may configure or update the spatial relationship of the SRS for the terminal.

[0209] In an example, the access network device 102 - 1 may send the indication information, the request message and / or the measurement result to the core network device 102 - 2 through the same NRPPa message.

[0210] In an example, the access network device 102 - 1 may send the indication information, the request message, and the measurement result to the core network device 102 - 2 through different NRPPa messages.

[0211] In step S2105 , the core network device 102 - 2 sends configuration information to the access network device 102 - 1 .

[0296] In some embodiments, the terminal 101 may send the request message to the access network device 102 - 1 or the core network device 102 - 2 .

[0297] In some embodiments, the terminal 101 may send the request message to the access network device 102 - 1 or the core network device 102 - 2 via a first message or a second message different from the first message.

[0298] In some embodiments, the optional implementation of step S3102 can refer to the optional implementation of step S2102 in Figure 2A or step S2202 in Figure 2B, and other related parts in the embodiments involved in Figure 2A or Figure 2B, which will not be repeated here.

[0299] Step S3103: Send the measurement result.

[0300] In some embodiments, the measurement results may be used by the network device to update the spatial relationship of the SRS.

[0301] In some embodiments, the terminal 101 may send the measurement result to the access network device 102 - 1 or the core network device 102 - 2 .

[0310] In some embodiments, the purpose of the terminal 101 acquiring the configuration information may be to enable the terminal 101 to resume SRS transmission based on the updated spatial relationship of the SRS.

[0311] For example, the reason for suspending SRS transmission includes that the spatial relationship of the SRS does not meet the conditions for sending the SRS, or the reference signal associated with the spatial relationship of the SRS cannot meet the measurement requirements, indicating that the beam direction of the transmitted SRS and the spatial relationship cannot be associated with the corresponding reference signal, or the associated reference signal quality is poor. Therefore, the spatial relationship of the SRS can be configured or updated by a network device, such as a core network device or an access network device. Terminal 101 can resume SRS transmission based on the updated spatial relationship of the SRS.

[0400] In the above embodiment, the core network device can determine the suspension or resumption of SRS transmission based on the indication information, thereby avoiding the waste of signaling resources caused by the core network device triggering the access network device to measure SRS without knowing the SRS transmission status, and then reconfiguring SRS for the terminal, thereby improving the reliability of uplink positioning and / or uplink and downlink hybrid positioning.

[0401] The above method is further illustrated below with examples.

[0402] The present disclosure provides the following information transmission method:

[0403] Method 1: During uplink positioning and / or uplink and downlink hybrid positioning, the terminal sends indication information to the access network device via RRC signaling, where the indication information is used to instruct the SRS transmission to be suspended or resumed. Further, the access network device may provide the indication information to the core network device.

[0404] Method 2: The terminal directly sends the indication information to the core network device through an LPP message, especially in a multi-round trip time (multi-RTT) scenario.

[0405] In the above method 1 and method 2, the terminal may indicate the reason for suspending or resuming SRS transmission.

[0406] In the embodiment of the present disclosure, when the terminal suspends and / or resumes SRS transmission, it sends indication information to the network device, where the indication information is used to instruct the suspension and / or resumption of SRS transmission.

[0407] Based on the above description, the SRS is an SRS configured with a validity area.

[0408] Based on the above description, the suspension reason is that the spatial relation of the configured SRS no longer meets the requirement for transmitting the SRS, or the reference signal associated with the spatial relation of the SRS cannot meet the measurement requirement.

[0409] The restoration reason is that the spatial relationship of the SRS meets the requirement for transmitting the SRS, or the reference signal associated with the spatial relationship of the SRS meets the measurement requirement.

[0410] Based on the above description, the terminal may send the indication information to the access network device, such as the gNB, for example, via an RRC message. The RRC message includes, but is not limited to, any of the following: terminal positioning assistance information; terminal assistance information; and an RRC reconfiguration complete message.

[0411] Based on the above description, the gNB may send the indication information to a core network device, such as an LMF, for example, by sending the indication information via an NRPPa message. The NRPPa message includes, but is not limited to, any of the following: a positioning information update message; a transmission reception point TRP information update message.

[0412] Based on the above description, the terminal sends the indication information to the LMF through an LPP message. The LPP message may include but is not limited to any of the following: an LPP request assistance information message; an LPP provide location information message.

[0413] Based on the above description, the RRC message sent by the terminal to the gNB, the NRPPa message sent by the gNB to the LMF, or the LPP message sent by the terminal to the LMF may also include the suspension reason and / or resumption reason of the SRS transmission.

[0414] Based on the above description, the RRC message sent by the terminal to the gNB, the NRPPa message sent by the gNB to the LMF, or the LPP message sent by the terminal to the LMF may also include:

[0415] A request message, wherein the request message is used to request the network device to update the spatial relationship of the SRS;

[0416] Measurement results, such as measurement results for different beams, RSRP, etc.

[0417] Based on the above description, the LMF determines the timing to trigger the gNB to measure SRS, that is, not to trigger the gNB to measure SRS during the SRS suspension phase.

[0418] Based on the above description, the gNB or LMF configures or updates the SRS spatial relation for the terminal.

[0419] In embodiment 1, new enumeration types "suspend" and "resume" are added to the SRS Transmission Status IE of the positioning information update message.

[0420] If the SRS Transmission Status IE is included in the Positioning Information Update message and is set to "Paused", the LMF shall consider SRS transmission to be suspended.

[0421] If the SRS Transmission Status IE is included in the Positioning Information Update message and is set to "Resume", the LMF shall consider that SRS transmission has been resumed (or requested to be resumed).

[0422] In embodiment 2, the SRS Transmission Status IE is multiplexed. If the gNB receives an indication from the terminal indicating that SRS transmission is suspended or resumed, the gNB carries a cause value in the POSITIONING INFORMATION UPDATE message sent to the LMF, which can be set to "UE suspends" or "UE resumes". The LMF determines the cause of the SRS transmission interruption or resumption based on the cause value.

[0423] The embodiments of the present disclosure further provide an apparatus for implementing any of the above methods. For example, an apparatus is provided, comprising units or modules for implementing each step performed by a network device (e.g., a core network device) in any of the above methods.
