Description

Technical Field

[0001] Cross-reference to Related Applications This application claims the priority of Chinese Patent Application No. 202310431205.4, filed in China on April 21, 2023, the entire content of which is incorporated herein by reference. The present disclosure relates to the technical field of mobile communications, and specifically, to a reference signal configuration method, a terminal, a network device, and a storage medium.

Background Art

[0002] The New Radio (NR) system strengthens high-precision and low-power positioning technologies to achieve goals such as positioning accuracy of less than 1 m, positioning interval of 15 - 30 s, and battery life of 6 - 12 months. To meet the above battery life requirements, it is necessary to further strengthen positioning based on positioning for UEs in RRC_INACTIVE state. The specific content includes enhancements related to positioning such as extending the Extended Discontinuous Reception (eDRX) cycle, and enhancements to the configuration of the Sounding Reference Signal for positioning (SRS for positioning) in the inactive state.

[0003] In related technologies, the Sounding Reference Signal (SRS) for positioning in the inactive state is configured by the serving cell. If the terminal loses Timing Advance validation (TA validation) due to reasons such as mobility, the SRS configuration for positioning in the inactive state becomes invalid, and the terminal needs to re-enter the connected state to obtain a valid SRS configuration for positioning. As a result, the battery life of the terminal decreases due to frequent entry into the connected state.

Furthermore, features described with reference to a particular example may be combined in other examples.

[0040] Referring to Figure 1, Figure 1 shows a block diagram of a wireless communication system applicable to embodiments of the present disclosure. The wireless communication system includes a terminal 11 and network equipment 12. Of these, the terminal 11 may be referred to as a user terminal or user equipment (UE). The terminal 11 may be a terminal-side device such as a mobile phone, tablet PC (Tablet Personal Computer), laptop computer, personal digital assistant (PDA), mobile internet device (MID), wearable device, or in-vehicle equipment, but it should be noted that the specific type of terminal 11 is not limited in embodiments of the present disclosure. The network equipment 12 may be a base station and / or a network element of a core network. Among these, the base station may be a base station of 5th Generation Mobile Communication Technology (5G) or later versions (e.g., the next-generation base station (the next-generation Node B, gNB), 5G NR Node B (Node B, NB), etc.), or a base station in other communication systems (yeNB, Wireless Local Area Network (WLAN) access point, or other access point, etc.). The base station may be referred to as Node B, Evolved Node B, access point, Base Transceiver Station (BTS), radio base station, radio transceiver, Basic Service Set (BSS), Extended Service Set (ESS), B node, Evolved Node B (eNB), Home B node, Home Evolved B node, WLAN access point, Wireless Fidelity (WiFi) node, or any other appropriate term in the aforementioned field, but the base station is not limited to any particular technical term as long as the same technical effect is achieved.In the embodiments described herein, a base station in an NR system is used as an example, but the specific type of base station is not limited.

[0041] A base station can communicate with a terminal 11 under the control of a base station controller, and in various examples, the base station controller may be part of a core network or several base stations. Some base stations can communicate control information or user data with the core network via backhaul. In some examples, some of these base stations can communicate with each other directly or indirectly via a backhaul link, which may be a wired or wireless link. The wireless communication system can support operation with multiple carriers (waveform signals of different frequencies). A multi-carrier transmitter can simultaneously transmit modulated signals on these multiple carriers. For example, each communication link may be a multi-carrier signal modulated by various wireless technologies. Each modulated signal can be transmitted on a different carrier and can carry control information (e.g., reference signals, control channels, etc.), overhead information, data, etc.

[0042] A base station can wirelessly communicate with a terminal 11 via one or more access point antennas. Each base station can provide communication coverage to a corresponding coverage area. The coverage area of ​​an access point can be divided into sectors that constitute only a portion of that coverage area. The wireless communication system may include different types of base stations (e.g., macro base stations, micro base stations, or pico base stations). Base stations may also utilize different wireless technologies, such as cellular or WLAN wireless access technologies. Base stations may be associated with the same or different access networks or carrier deployments. The coverage areas of different base stations (including coverage areas of the same or different types of base stations, coverage areas utilizing the same or different wireless technologies, or coverage areas belonging to the same or different access networks) may overlap.

[0043] A communication link in a wireless communication system may include an uplink for carrying uplink (UL) transmission (e.g., transmission from terminal 11 to network equipment 12) or a downlink for carrying downlink (DL) transmission (e.g., transmission from network equipment 12 to terminal 11). UL transmission can also be called reverse link transmission. DL transmission, on the other hand, can also be called forward link transmission. Downlink transmission may be carried out using a licensed frequency band, an unlicensed frequency band, or both. Similarly, uplink transmission may be carried out using a licensed frequency band, an unlicensed frequency band, or both.

[0044] Release 17 (version 17) of the NR system positioning supports a technology that allows positioning terminals with energy-saving requirements to transmit positioning SRS while inactive. The positioning SRS transmitted by the terminal while inactive consists of a Radio Resource Control Release (RRC Release) message and specifically includes the following: 1) Positioning SRS resource set and resource configuration: Includes resource set identifier, resource identifier, resource mapping pattern, power control parameters (including path loss reference signal (pathloss RS)), spatial relation information (including spatial relation reference signal (spatial relation RS)), etc., and supports periodic and semi-persistent positioning SRS in the time domain type. Among these, the pathloss RS of the positioning SRS may be combined with the synchronization signal block (SSB) and downlink positioning reference signal (DL PRS) of the serving cell or neighboring cell. If the terminal is inactive and cannot accurately measure the pathloss RS, the terminal stops transmitting the positioning SRS. Spatial relation RS: The spatial relation RS of a positioning SRS may be combined with the serving cell's or neighboring cell's SSB, DL PRS, serving cell's channel state information reference signal (CSI-RS), multiple-in multiple-out (MIMO) SRS, or positioning SRS. If the terminal is in an inactive state and cannot accurately measure the spatial relation RS, the terminal stops transmitting the positioning SRS. 2) Bandwidth Part (BWP) Configuration: By default, the positioning SRS is configured within the initial uplink bandwidth portion (initial UL BWP) of the User Equipment (UE). The positioning SRS may be configured outside the UE initial UL BWP to achieve high positioning accuracy, but this depends on the capabilities of the UE. 3) Timing Advance Timer (TA timer): This is the TA timer for the inactive positioning SRS. Its value refers to the Small Data Transmission (SDT) Timing Advance Timer (TA timer). When this timer times out, it indicates that the configured inactive positioning SRS is invalid, and the UE must re-enter the connection state to obtain a valid positioning SRS configuration. 4) Timing Advance (TA) Validation (TA validation): This is based on the TA validity determination standard for the Reference Signal Received Power (RSRP). If the RSRP fluctuation of the reference signal (SSB) for TA validation exceeds a configured threshold, it means that the configured inactive positioning SRS is invalid, and the UE needs to re-enter the connected state to obtain a valid positioning SRS configuration.

[0045] As mentioned above in the background technology section, the inactive state positioning SRS is composed of serving cells. If the terminal loses TA validation due to mobility or other reasons, the inactive state positioning SRS configuration becomes invalid, and the terminal needs to re-enter the connected state to acquire the configuration. Frequent re-entry into the connected state reduces the battery life of the terminal.

[0046] To enhance the inactive state positioning SRS configuration, one solution is to support SRS mobility, i.e., an inactive state positioning SRS configuration that is effective within multiple cells (effective areas). Supporting an effective area-based SRS configuration requires solving the following problems: First, there is the problem that downlink synchronization based on SSB can increase the length of time the terminal is awake and consuming power. For the terminal to transmit positioning SRS, it needs to adjust the TA based on downlink synchronization, and for low-power, high-precision positioning terminals, their eDRX cycle and SRS cycle can be several tens of seconds, during which time the terminal enters sleep mode, making it difficult to maintain accurate downlink synchronization. Conventional downlink synchronization requires monitoring the SSB, but the SSB is cell-specific and can be far away in the time domain from the inactive SRS, which increases the length of time the terminal is awake and consuming power. Next, regarding the issues of power control and spatial relations, conventional pathloss RS and spatial relation RS are both constructed based on the serving cell where the terminal is located, making it difficult to directly apply them to the effective area of ​​multiple cells.

[0047] To address one or more of the above problems, embodiments of the present disclosure provide a reference signal configuration method applicable to the configuration and transmission of an inactive uplink positioning reference signal (e.g., SRS) in an effective area.

[0048] Referring to Figure 2, the method for configuring an uplink positioning reference signal (e.g., SRS) according to an embodiment of the present disclosure, when applied to a terminal, includes the following step 21. Step 21 is the first information transmitted from the network, First instruction information for determining the uplink positioning reference signal resource transmitted by the terminal while it is inactive, Secondary instruction information to point to at least one cell, First configuration information for configuring at least one uplink positioning reference signal resource for at least one of the aforementioned cells, The first information includes at least one of the following: a second configuration information for configuring at least one downlink reference signal resource for the aforementioned at least one cell.

[0049] Here, the first information may be carried within a Radio Resource Control (RRC) release message and / or System Information Block (SIB) signaling transmitted from the network. The uplink reference signal resource is a resource that transmits the uplink reference signal, and the downlink reference signal resource is a resource that transmits the downlink reference signal. Specifically, the first configuration information of each uplink reference signal resource may include at least one of the following: resource set identifier, resource identifier, time domain type, period, slot offset, transmit comb, sequence identifier, bandwidth portion (BWP) configuration information, timing advance timer (TA timer) configuration information, and reference signal received power (RSRP) change threshold.

[0050] The uplink positioning reference signal resource configured within the first configuration information is configured for the at least one cell included in the second instruction information, and the downlink reference signal resource configured within the second configuration information is also configured for the at least one cell included in the second instruction information. That is, the at least one uplink positioning reference signal resource within the first configuration information is applicable to the at least one cell included in the second instruction information, and the at least one downlink reference signal resource within the second configuration information is applicable to the at least one cell included in the second instruction information.

[0051] The first instruction information is for determining, from among the at least one uplink positioning reference signal resource configured within the first configuration information, the uplink positioning reference signal resource to which the terminal transmits the uplink positioning reference signal in an inactive state.

[0052] The aforementioned second instruction information is for indicating at least one cell, and may selectively indicate N cells, where N is an integer of 2 or more. Specifically, a specific cell may be indicated via a Physical Cell Identifier (PCI), etc.

[0053] Furthermore, in this specification, the uplink positioning reference signal resource may be an uplink positioning reference signal resource set and / or a resource composed within an uplink positioning reference signal resource set. The downlink reference signal resource may be a downlink reference signal resource set and / or a resource composed within a downlink reference signal resource set.

[0054] One specific implementation method is that the first instruction information may be an association relationship between the uplink positioning reference signal resource and the downlink reference signal resource. In this way, the terminal can determine the uplink positioning reference signal resource associated with the first downlink reference signal resource as one or more uplink positioning reference signal resources that transmit uplink positioning reference signals, depending on the association relationship between the first downlink reference signal resource and the uplink positioning reference signal resource.

[0055] By the steps described above, the embodiments of the present disclosure extend the uplink positioning reference signal resource configuration in the inactive state to the at least one cell, thereby preventing the problem of the terminal frequently entering a connected state due to the uplink positioning reference signal resource configuration becoming invalid when the terminal moves within the at least one cell. This reduces the frequency with which the terminal enters a connected state to acquire the uplink positioning reference signal resource configuration, thereby reducing the terminal's power consumption and improving battery life.

[0056] Furthermore, in embodiments of this disclosure, the terminal may receive second information transmitted from the network, which indicates an available first downlink reference signal resource from among the at least one downlink reference signal resource, and may determine the currently available first downlink reference signal resource in accordance with the second information. Specifically, the second information may be carried in a message such as a Paging Early Indication (PEI), a paging message, a Message (Msg)4, or MsgB.

[0057] Selectively, in embodiments of the present disclosure, the first information further includes third instruction information for indicating the index of an instruction bit corresponding to a downlink reference signal resource. Specifically, the third instruction information may be a bitmap containing instruction bits corresponding to each downlink reference signal resource. For example, in the second information transmitted from the network, the value of the instruction bit corresponding to the first downlink reference signal resource is a preset value, for example, if the value is 1, it indicates that the downlink reference signal resource corresponding to the instruction bit is available, and if the value is 0, it indicates that the downlink reference signal resource corresponding to the instruction bit is unavailable. Of course, the above value may be 1 for unavailable and 0 for available, but the present disclosure is not specifically limited thereto.

[0058] Furthermore, after step 21 above, the terminal may determine the resources to which the terminal transmits the uplink positioning reference signal while in an inactive state. Specifically, determining the resources to which the terminal transmits the uplink positioning reference signal while in an inactive state means Based on the currently available first downlink reference signal resource, receive the downlink reference signal, Based on the first downlink reference signal resource and the first instruction information, one or more uplink positioning reference signal resources that transmit uplink positioning reference signals are determined, The first spatial domain transmission filter that transmits the uplink positioning reference signal is determined to be the same as the first spatial domain transmission filter that receives the downlink reference signal. This may include at least one of the following: estimating path loss based on the received downlink reference signal, and determining the transmission power of the uplink positioning reference signal resource according to the path loss.

[0059] In other words, the power control information and spatial relation information transmitted with the uplink positioning reference signal may be determined by the downlink reference signal.

[0060] Figures 3-4 provide a specific example of the above method of the embodiment of the present disclosure, in which it is assumed that the network has configured three uplink positioning SRSs (SRS1-3) and three downlink reference signals (TRS A-C) via RRC Release or SIB messages. TRS A is associated with SRS1 and corresponds to the first bit in the bitmap, TRS B is associated with SRS2 and corresponds to the second bit in the bitmap, and so on. If the second bit in the bitmap carried in the PEI received by the terminal is 1, i.e., if TRS B is available at this time, the terminal determines the power control and spatial relation info based on the configuration of TRS B and transmits SRS2 associated with TRS B accordingly.

[0061] Furthermore, in the embodiments of this disclosure, the time-domain interval between the first downlink reference signal resource and the one or more uplink positioning reference signal resources is less than the preset time length. In this way, the problem of the terminal waking up and consuming power for a long time due to SSB synchronization is improved, and the terminal's power consumption can be saved.

[0062] In embodiments of this disclosure, the RSRP change threshold in the TA validation criterion may be obtained in response to a downlink reference signal configured by the network. The RSRP change in the criterion simply indicates that a positioning reference signal (e.g., SRS) previously indicated as available is no longer applicable. In this case, the terminal can request updates of available tracking reference signals (TRS) and associated positioning reference signal resources from the network via a Random Access Channel (RACH) procedure without entering a connected state. That is, the terminal can save power consumption by updating available positioning SRS resources in response to changes in location in a timely manner between two paging occasions without entering a connected state.

[0063] Specifically, in an embodiment of the present disclosure, the terminal may send Msg3 or MsgA to the network to request an update of available downlink reference signal resources if the RSRP change amount of the downlink reference signal exceeds the RSRP change threshold. The terminal then receives Msg4 or MsgB from the network, obtains the updated second downlink reference signal resource and its associated second uplink reference signal resource from Msg4 or MsgB, and transmits an uplink reference signal based on the second uplink reference signal resource.

[0064] Furthermore, to reduce TA inaccuracies, the terminal may perform adaptive TA adjustment according to the arrival time difference of two downlink reference signals, i.e., TA_delta becomes twice the arrival time difference. Specifically, the terminal may receive two downlink reference signals transmitted from the network in an inactive state, calculate the arrival time difference of the two downlink reference signals, then adjust the current timing advance amount according to the arrival time difference to obtain the adjusted timing advance amount, and transmit an uplink positioning reference signal based on the adjusted timing advance amount. Here, the adjusted timing advance amount is the original timing advance amount plus twice the arrival time difference. Figure 5 provides an example diagram showing adaptive TA adjustment according to the arrival time difference of two downlink reference signals. The adjusted TA = TA1 + TA_delta, where TA1 is the original TA.

[0065] In embodiments of the present disclosure, the network may configure only one downlink reference signal resource for the at least one cell, in which case the first information includes only one downlink reference signal resource configured in the second configuration information, and the network may transmit in the form of a Single Frequency Network (SFN) when transmitting downlink reference signals within the at least one cell. Since only one downlink reference signal resource is included, the first information may not include the first instruction information, i.e., the first instruction information may be omitted. In this case, the above method of embodiments of the present disclosure may be further simplified to the following methods which are more advantageous for terminal power saving. (1) If the first instruction information is omitted, the terminal receives a downlink reference signal transmitted from at least one cell, and then sets the timing of the downlink reference signal with the largest RSRP as the downlink timing, or the earliest arrival time among the downlink reference signals as the downlink timing. Then, downlink synchronization is performed based on the downlink timing. Here, the earliest arrival time among the downlink reference signals may specifically be the earliest arrival time among the downlink reference signals whose RSRP exceeds the preset RSRP threshold. (2) If the first instruction information is omitted, the at least one uplink positioning reference signal resource includes N uplink positioning reference signal resources, where N is an integer greater than 1. Typically, N is greater than or equal to the number of transmit beams of the terminal. In this case, the terminal transmits the N uplink positioning reference signal resources using different spatial domain transmission filters.

[0066] Referring to Figure 6, the reference signal configuration method according to the embodiment of the present disclosure, when applied to network equipment (e.g., a base station), includes the following step 61. Step 61 is the first information, First instruction information for determining the uplink positioning reference signal resource transmitted by the terminal while it is inactive, Secondary instruction information to point to at least one cell, First configuration information for configuring at least one uplink positioning reference signal resource for at least one of the aforementioned cells, The first information is transmitted to the terminal, which includes at least one of the following: first information and second configuration information for configuring at least one downlink reference signal resource for at least one of the aforementioned cells.

[0067] Specifically, network equipment may carry the first information in an RRC release message and / or SIB signaling and transmit it to the terminal.

[0068] The uplink positioning reference signal resource configured within the first configuration information and the downlink reference signal resource configured within the second configuration information are both configured for at least one cell included in the second instruction information.

[0069] The primary configuration information for each uplink positioning reference signal resource includes at least one of the following: uplink positioning reference signal resource set identifier, resource identifier, time domain type, period, slot offset, transmit comb, sequence identifier, BWP configuration information, TA timer configuration information, and reference signal received power (RSRP) change threshold.

[0070] The first instruction information is for determining, from among the at least one uplink positioning reference signal resource configured within the first configuration information, the uplink positioning reference signal resource to which the terminal transmits the uplink positioning reference signal in an inactive state.

[0071] One specific implementation method is that the first instruction information may be an association relationship between the uplink positioning reference signal resource and the downlink reference signal resource. In this way, the terminal can determine the uplink positioning reference signal resource associated with the first downlink reference signal resource as one or more uplink positioning reference signal resources that transmit uplink positioning reference signals, depending on the association relationship between the first downlink reference signal resource and the uplink positioning reference signal resource.

[0072] By the steps described above, embodiments of the present disclosure can avoid or reduce the problem of frequent terminal entry into a connected state due to the inactivation of the uplink positioning reference signal resource configuration by extending the uplink positioning reference signal resource configuration to at least one cell, thereby reducing the frequency with which the terminal enters a connected state to acquire the uplink positioning reference signal resource configuration, reducing terminal power consumption, and improving battery life.

[0073] Furthermore, in embodiments of this disclosure, the network device may transmit second information to the terminal to indicate which of the at least one downlink reference signal resources is available, so that the terminal can determine which of the available downlink reference signal resources is currently available. The second information may also be carried in a message such as a PEI, paging message, Msg4, or MsgB.

[0074] Selectively, in embodiments of the present disclosure, the first information further includes third instruction information for indicating the index of an instruction bit corresponding to a downlink reference signal resource. The third instruction information may specifically be a bitmap containing instruction bits corresponding to each downlink reference signal resource. For example, in the second information transmitted from the network, the value of the instruction bit corresponding to the first downlink reference signal resource is a preset value, for example, if the value is 1, it indicates that the downlink reference signal resource corresponding to that instruction bit is available.

[0075] Furthermore, after step 61, the network device may determine one or more uplink positioning reference signal resources on which the terminal transmits the uplink positioning reference signal, based on the terminal's currently available first downlink reference signal resource and the first instruction information. The network device then receives the uplink positioning reference signal transmitted from the terminal on the one or more uplink positioning reference signal resources.

[0076] Selectively, the time-domain interval between the first downlink reference signal resource and the one or more uplink positioning reference signal resources is less than a preset time length. This improves the problem of the terminal waking up and consuming power for a long time due to SSB synchronization.

[0077] Furthermore, in embodiments of the present disclosure, the terminal may send a Msg3 or MsgA to the network to request an update of available downlink reference signal resources if the RSRP change amount of the downlink reference signal exceeds the RSRP change threshold. In this case, the network equipment receives the Msg3 or MsgA sent from the terminal when the RSRP change amount of the downlink reference signal exceeds the RSRP change threshold, and then sends a Msg4 or MsgB to the terminal to indicate the updated second downlink reference signal resource and the associated second uplink positioning reference signal resource, so that the terminal transmits an uplink positioning reference signal based on the second uplink positioning reference signal resource.

[0078] Selectively, the first information may not include the first instruction information, i.e., the first instruction information may be omitted, and the at least one uplink positioning reference signal resource may include N uplink positioning reference signal resources, where N is an integer greater than 1, in which case the network device may receive the N uplink positioning reference signal resources transmitted from the terminal using different spatial domain transmission filters.
