Description

Technical Field

[0001] This application belongs to the field of mobile communication technology, and specifically relates to a method, apparatus, terminal and network-side equipment for transmitting a detection reference signal. Background Technology

[0002] Configuring a sounding reference signal (SRS) for a terminal can be used for terminal positioning, channel quality detection and estimation, beam management, and other purposes. By aggregating sounding reference signals from different carriers, the total number and / or total bandwidth of the sounding reference signals can be increased, thereby improving the accuracy of the measurement results.

[0003] When configuring other carriers to transmit sounding reference signals, the corresponding secondary cell needs to be active. After the secondary cell is activated, the bandwidth portion (BWP) of the dormant bandwidth portion (BWP), also known as the partial bandwidth, needs to be activated in order to transmit sounding reference signals on that carrier.

[0004] During the transmission of the probe reference signal, the terminal needs to continuously listen to the Physical Downlink Control Channel (PDCCH) of the active secondary cell.

[0068] The method for transmitting a detection reference signal provided in this application will be described in detail below with reference to the accompanying drawings and through some embodiments and application scenarios.

[0069] like Figure 2 As shown in the illustration, this application provides a method for transmitting a detection reference signal. The execution entity of this method is a first network-side device, which can be an access network device, specifically a base station (gNB) or TRP of the serving cell where the terminal is located. In other words, this method can be executed by software or hardware installed on the first network-side device. The method includes the following steps.

[0070] Step 210: The first network-side device receives first information from the second network-side device, the first information being used to request the configuration of a first detection reference signal for the terminal in the secondary cell.

[0071] The second network-side device can be a core network device, or a function used to implement various measurement tasks, such as a Location Management Function (LMF). For simplicity, the following embodiments will use LMF as the second network-side device for illustration.

[0072] Before sending the first information, the second network-side device needs to obtain the base station's configuration information or TRP configuration information through interaction with the base station.

[0073] Before selecting a positioning method, the second network-side device needs to interact with the terminal to obtain the terminal's capability information in order to determine whether the terminal supports cross-carrier transmission of probe reference signals.

[0074] In one implementation, the capability information may include at least one of the following:

[0075] The terminal supports cross-carrier transmission of probe reference signals;

[0076] The number of carriers supported by at least one frequency band;

[0077] Parameter configuration for the bandwidth portion of the carrier.

[0078] It is evident that the capability information includes not only an indication of whether the terminal supports cross-carrier transmission of probe reference signals, but also capability information regarding the carrier granularity supported by the terminal.

[0079] If the second network-side device determines that positioning is based on the uplink probe reference signal, then when it determines that the terminal supports cross-carrier probe reference signal transmission, it sends first information to the first network-side device, requesting the first network-side device to configure a first probe reference signal for the terminal in the secondary cell.

[0080] The first information may carry the requested SRS transmission characteristics, including relevant parameters of the probe reference signal, such as the bandwidth and type of the probe reference signal. It may also carry more granular SRS parameters in the first information based on the terminal's capability information.

[0081] In one implementation, the first information further includes at least one of the following:

[0082] The number of carriers on at least one frequency band;

[0083] Carrier configuration information.

[0084] In one implementation, the carrier configuration information includes at least one of the following:

[0085] Carrier bandwidth;

[0086] The carrier frequency number (Absolute Radio Frequency Channel Number, ARFCN) of SRS;

[0087] Parameters of the sounding reference signal resource set (SRS Resource Set) on the carrier wave.

[0088] Step 220: If the first condition is met, send an activation instruction to the terminal, the activation instruction being used to activate the configuration of the first detection reference signal.

[0089] The first condition includes at least one of the following:

[0090] The auxiliary cell is in an inactive state;

[0091] The terminal was not configured with a secondary cell.

[0092] The terminal supports a target bandwidth portion; wherein, the target bandwidth portion is the bandwidth portion used to transmit the first detection reference signal.

[0093] It should be understood that this application embodiment introduces a new state in which the terminal can transmit a first detection reference signal through a secondary cell, and the terminal does not perform at least one of the following in the new state:

[0094] Data is transmitted on the UpLink Shared Channel (UL-SCH) of the secondary cell;

[0095] Data is transmitted via the Physical Random Access Channel (PRACH) in the secondary cell;

[0096] Monitor the Physical Downlink Control Channel (PDCCH) of the secondary cell;

[0097] Data is transmitted on the Physical Uplink Control Channel (PUCCH) of the secondary cell.

[0098] The first network-side device can determine whether the terminal meets the first condition when it is determined that the terminal supports the new state, and send an activation instruction to the terminal to configure the first detection reference signal in the secondary cell according to the determination result.

[0099] In one implementation, the activation indication can be sent via Radio Resource Control (RRC) information, such as an RRC Reconfiguration message, an RRC Resume message, or an RRC Release message. The first probe reference signal is activated by introducing an activation indication for the uplink probe reference signal into the RRC message.

[0100] The activation indication can be set according to actual needs. In one embodiment, the activation indication can be an activation indication for the entire detection reference signal. The entire detection reference signal can include a first type of detection reference signal and a second type of detection reference signal. The first type of detection reference signal is a conventional type of detection reference signal, which can be represented as SRS in the protocol. The second type of detection reference signal is a detection reference signal used to carry positioning information, which is represented as Positioning SRS in the protocol.

[0101] In another implementation, the activation indication may be an activation indication for only the first type of probe reference signal or an activation indication for the second type of probe reference signal.

[0102] In another implementation, the activation indication may be an activation indication for a resource set of various types of probe reference signals. It may be an activation indication for one or more resource sets in a first type of probe reference signal, or an activation indication for one or more resource sets in a second type of probe reference signal.

[0103] In another implementation, the activation indication may be an activation indication for resources in a resource set, or an activation indication for a probe reference signal for one or more resources of a first type of probe reference signal, or an activation indication for a probe reference signal for one or more resources of a second type of probe reference signal.

[0104] In one implementation, it is required that the number of bandwidth portions of the first detection reference signal configured on each secondary cell be 1.

[0105] In one implementation, the terminal may be in a Radio Resource Control Connected (RRC-Connected) state or a Radio Resource Control Inactive (RRC-Inactive) state, that is, the terminal supports transmitting the first probe reference signal on the secondary cell in the RRC-Inactive state.

[0106] In one implementation, when the terminal receives an RRC message upon entering the RRC-Inactive state, such as an RRC release with suspendconfig message, which includes an activation indication for the first probe reference signal, the terminal can continue to transmit the first probe reference signal through the secondary cell based on the activation indication.

[0107] Furthermore, after step 230, the method further includes:

[0108] The first network-side device performs measurements based on the measured first and / or second detection reference signals, obtains measurement results, and sends the measurement results to the second network-side device.

[0109] As can be seen from the technical solutions provided by the above embodiments, in this application embodiment, a first network-side device receives first information from a second network-side device. This first information is used to request the configuration of a first probe reference signal for the terminal in a secondary cell. If a first condition is met, an activation instruction is sent to the terminal, which is used to activate the configuration of the first probe reference signal. This application embodiment introduces a new state, enabling the terminal to configure the first probe reference signal in a secondary cell when the first condition is met. Therefore, when sending the first probe reference signal, it is not necessary to perform channel listening on the secondary cell, thereby reducing additional terminal power consumption.

[0110] Based on the above embodiments, the activation indication is further related to the operating status of the secondary cell.

[0111] In one implementation, when the first network-side device determines that the secondary cell is in an active state, it does not send an activation instruction to the terminal, that is, it does not need to configure the first detection reference signal for the terminal.

[0112] At this time, the terminal can send the corresponding probe reference signal through the active secondary cell, which means that there is no need to consider reducing the terminal power consumption.

[0113] In another implementation, when the first network-side device determines that the secondary cell is in an inactive state, the first network-side device sends the activation instruction to the terminal to configure the terminal to activate the first probe reference signal on the inactive secondary cell.

[0114] At this time, the terminal can send the first detection reference signal through the inactive secondary cell according to the configuration of the first detection reference signal.

[0115] In another implementation, if it is determined that the terminal has not been configured with a secondary cell, the first network-side device may also send first configuration information to the terminal when sending the activation instruction. The first configuration information is used to configure a secondary cell for the terminal.

[0116] By sending first configuration information and activation indication to the terminal, a secondary cell is configured for the terminal, and an activation indication for the detection reference signal is configured, and the first detection reference signal is configured on the secondary cell.

[0117] In one implementation, the secondary cell configured for the terminal is an inactive secondary cell.

[0118] It should be understood that the activation indication and the first configuration information may be the same information, which can be sent via RRC messages, such as RRC Reconfiguration, RRC Resume, or RRC Release messages.

[0119] At this time, the terminal can send a first detection reference signal through the inactive secondary cell configured by the first configuration information according to the activation instruction.

[0120] As can be seen from the technical solutions provided by the above embodiments, the embodiments of this application determine the activation indication to be sent to the terminal based on whether the secondary cell is in an active state and whether the terminal is configured with a secondary cell, so that the terminal can send a first probe reference signal through the inactive secondary cell without channel listening to the secondary cell, thereby reducing additional terminal power consumption.

[0121] Based on the above embodiments, the activation indication is further related to the bandwidth portion supported by the terminal.

[0122] If it is determined that the terminal supports the target bandwidth portion, the first network-side device may also send second configuration information to the terminal when sending the activation instruction. The second configuration information is used to configure the target bandwidth portion in the secondary cell.

[0123] Even if the secondary cell is active, if the terminal supports the target bandwidth portion, it can configure the target bandwidth portion under the active secondary cell using the second configuration information, and then configure the first probe reference signal for the target bandwidth portion under the secondary cell using the activation indication. At this time, the terminal can still transmit the first probe reference signal through the secondary cell in the first state.

[0124] In one implementation, the target bandwidth portion may be a first bandwidth portion, which is used only for transmitting the first probe reference signal. The configuration information of the first bandwidth portion may include an indication to transmit only the uplink reference signal, i.e., an indication to transmit the first probe reference signal, which may be represented as srsOnly.

[0125] When the first network-side device determines that the terminal supports the first bandwidth portion, it can configure the first bandwidth portion for the secondary cell through the second configuration information and activate the first bandwidth portion through an activation instruction.

[0126] In another implementation, the target bandwidth portion may also be a second bandwidth portion, which is a sleep bandwidth portion including the activation or enable indication of the first probe reference signal, and may be represented as srsState.

[0127] When the first network-side device determines that the terminal supports the second bandwidth portion, it can configure the second bandwidth portion for the secondary cell through the second configuration information and activate the second bandwidth portion through the activation instruction.

[0128] It should be understood that the second configuration information and the activation indication may be the same configuration information or activation indication, which can be sent via RRC messages, such as RRC Reconfiguration, RRC Resume, or RRC Release messages.

[0129] As can be seen from the technical solutions provided by the above embodiments, in the case where the terminal supports the target bandwidth portion, the first network-side device can configure and activate the target bandwidth portion for the secondary cell, enabling the terminal to send the first probe reference signal in the target bandwidth portion of the secondary cell without needing to perform channel listening on the secondary cell, thereby reducing additional terminal power consumption.

[0130] Based on the above embodiments, further, as Figure 3 As shown, the triggering condition for the terminal to send the detection reference signal can be set according to actual needs. For example, it can be sent according to a preset period or according to the received activation information.

[0131] In one embodiment, when the first detection reference signal is an aperiodic or semi-persistent detection reference signal, after step 220, the method further includes:

[0132] Step 230: The first network-side device sends activation information to the terminal, the activation information being used to activate the terminal to send the first detection reference signal.

[0133] In one implementation, the activation information originates from a second network-side device.

[0134] In one implementation, the activation information is transmitted in the form of a Media Access Control Element (MAC CE) or Downlink Control Information (DCI); wherein the activation information carries an enable flag for the first probe reference signal. The MAC CE can be a new MAC CE, or it can be based on an existing MAC CE using a reserved bit R, such as... Figure 5 The MAC CE shown uses a reserved bit 0 as the enable flag for the first probe reference number. When the enable flag is 1, the terminal triggers the transmission of the probe reference signal.

[0135] Furthermore, such as Figure 4 As shown, after step 230, the method further includes:

[0136] Step 240: Measure the first detection reference signal and / or the second detection reference signal to obtain the measurement result; wherein, the second detection reference signal is the second detection reference signal of the terminal measured through the primary cell (Pcell) or primary-secondary cell (PScell) where the terminal is located.

[0137] When the terminal sends a first detection reference signal through the secondary cell according to the activation instruction, it can also send a second detection reference signal through the primary cell or the primary and secondary cells.

[0138] The terminal, based on its own capabilities, can simultaneously transmit a first detection reference signal through a secondary cell and a second detection reference signal through a primary cell or a primary-secondary cell, without needing to switch on different carriers.

[0139] Furthermore, after step 240, the method further includes:

[0140] Step 250: Send the measurement results to the second network-side device.

[0141] like Figure 6As shown, an example of a complete signaling flow according to an embodiment of this application is given, wherein the second network-side device is an LMF and the first network-side device is a serving cell base station.

[0142] A1. The LMF interacts with the base station to obtain TRP information; the LMF and the base station exchange information based on the New Radio Positioning Protocol A (NRPPa). This step can be represented as an NRPPa TRP Configuration Information Exchange.

[0143] A2. The LMF interacts with the terminal to obtain the terminal's capability information; among which, the LMF and the base station exchange information based on the LTE Positioning Protocol (LPP). This step can be represented as LPP Capability Transfer.

[0144] A3. The LMF sends the first information to the serving cell base station. This step can be represented as an NRPPa Positioning Information Request.

[0145] A4. Serving cell base station determines activation indication. This step can be represented as the base station determining UL SRS Resources (gNB determines UL SRS Resources).

[0146] A5. The serving cell base station sends an activation indication to the terminal. This step can be represented as an RRC Reconfiguration message based on the RRC protocol, which carries UE SRSConfiguration (UE Detection Reference Information).

[0147] A6. The serving cell base station sends an activation indication to the LMF in response. This step can be represented as an NRPPa-based Positioning Information Response.

[0148] A7. The LMF sends activation information to the serving cell base station. This step can be represented as an NRPPa-based Positioning Activation Request.

[0149] A8. The serving cell base station sends activation information to the terminal. This step can be represented as activating UE SRS transmission.

[0150] A9. The serving cell base station sends an activation response to the LMF. This step can be represented as an NRPPa Positioning Activation Response.

[0151] A10. The terminal may send a probe reference signal, which may include sending a first probe reference signal through a secondary cell and sending a second probe reference signal through a primary cell or a primary and secondary cell.
