Description

Technical Field

[0001] This disclosure relates to the field of communication technology, and in particular to a method and apparatus for indicating the effectiveness of a reference signal. Background Technology

[0002] In 5G NR (New Radio) systems, the continuously transmitted CRS (Cell-specific Reference Signal) used for high-precision time-frequency tracking has been eliminated. Instead, the reference signal for time-frequency tracking is configured and triggered according to the needs of the terminal equipment. In NR, the Synchronization Signal Block / Physical Broadcast Channel Block (SSB) / PBCH (Physical Broadcast Channel Block), TRS (Tracking Reference Signal), or CSI-RS (Channel State Information-Reference Signal) are generally selected as the reference signal for time-frequency tracking.

[0056] To better understand the reference signal activation indication method disclosed in the embodiments of this application, the communication system to which the embodiments of this application are applicable is described below.

[0057] Please see Figure 1 , Figure 1 This application provides a schematic diagram of the architecture of a communication system according to an embodiment. The communication system may include, but is not limited to, a network device and a terminal device. Figure 1 The number and form of devices shown are for illustrative purposes only and do not constitute a limitation on the embodiments of this application. In actual applications, it may include two or more network devices and two or more terminal devices. Figure 1 The communication system shown is exemplified by a network device 101 and a terminal device 102.

[0058] It should be noted that the technical solutions of this application embodiment can be applied to various communication systems. For example, Long Term Evolution (LTE) systems, fifth-generation mobile communication systems, 5G New Radio systems, or other future new mobile communication systems.

[0059] The network device 101 in this embodiment is a network-side entity used for transmitting or receiving signals. For example, the network device 101 can be an evolved NodeB (eNB), a Transmission Reception Point (TRP), a Next Generation NodeB (gNB) in an NR system, a base station in other future mobile communication systems, or an access node in a Wireless Fidelity (WiFi) system. This embodiment does not limit the specific technology or device form used in the network device. The network device provided in this embodiment can be composed of a Central Unit (CU) and a Distributed Unit (DU). The CU can also be called a Control Unit. Using a CU-DU structure allows the protocol layer of a network device, such as a base station, to be separated. Some protocol layer functions are centrally controlled by the CU, while the remaining or all protocol layer functions are distributed in the DU, which is centrally controlled by the CU.

[0060] In this application embodiment, the terminal device 102 is a user-side entity used to receive or transmit signals, such as a mobile phone. The terminal device can also be referred to as a terminal, user equipment (UE), mobile station (MS), mobile terminal (MT), etc. The terminal device can be a car with communication capabilities, a smart car, a mobile phone, a wearable device, a tablet computer, a computer with wireless transceiver capabilities, a virtual reality (VR) terminal device, an augmented reality (AR) terminal device, a wireless terminal device in industrial control, a wireless terminal device in self-driving, a wireless terminal device in remote medical surgery, a wireless terminal device in a smart grid, a wireless terminal device in transportation safety, a wireless terminal device in a smart city, a wireless terminal device in a smart home, and so on. The embodiments of this application do not limit the specific technology or device form used in the terminal device.

[0061] The time-frequency tracking reference signal is a reference signal shared by network devices with non-connected UEs (User Equipment). In order to save system overhead, a window is usually set to reduce the system overhead caused by frequent change of effective indication. However, this adds extra overhead for systems with infrequent change of effective indication.

[0062] In the embodiments of this disclosure, a network device sends an activation indication message to a terminal device in a disconnected state. The activation indication message is used to indicate that the reference signal received by the terminal device within the activation time period corresponding to the activation indication message is effective. This allows the terminal device to receive the reference signal within the activation time period according to the configuration information, saving power and resources. The network device can also flexibly configure the activation time period to reduce system overhead.

[0063] It is understood that the communication system described in the embodiments of this application is for the purpose of more clearly illustrating the technical solutions of the embodiments of this application, and does not constitute a limitation on the technical solutions provided in the embodiments of this application. As those skilled in the art will know, with the evolution of system architecture and the emergence of new business scenarios, the technical solutions provided in the embodiments of this application are also applicable to similar technical problems.

[0064] The following description, in conjunction with the accompanying drawings, details the method and apparatus for indicating the effectiveness of the reference signal provided in this application.

[0065] Figure 2 This is a flowchart illustrating a method for indicating the activation of a reference signal according to an embodiment of this disclosure. It should be noted that the method in this embodiment is executed by a network device.

[0066] like Figure 2 As shown, the method for indicating the effectiveness of the reference signal includes the following steps: Step 201: Send an activation indication message to the terminal device in the non-connected state. The activation indication message is used to indicate that the reference signal received by the terminal device during the activation time period corresponding to the activation indication message is effective.

[0067] The disconnected state includes the idle state and the inactive state. In related technologies, a terminal device in the disconnected state can wake up when needed and perform time-frequency synchronization based on a received reference signal for time-frequency tracking. For example, the terminal device wakes up before the Paging Occasion (PO) position to receive the reference signal for time-frequency synchronization. Optionally, the reference signal is a synchronization signal block (SSB), a tracking reference signal (TRS), or a channel state information reference signal (CSI-RS).

[0068] It should be noted that network devices can flexibly configure the reference signal used for time-frequency tracking, such as the time domain resources, frequency domain resources, period, window, etc. of the reference signal, or use a fixed pattern to indicate the above information of the reference signal.

[0069] Additionally, it should be noted that the effective indication information is information configured by the network device to indicate that the reference signal received by the terminal device is effective. In other words, the effective indication information is used to indicate that the reference signal received by the terminal device is effective within the effective time period corresponding to the effective indication information.

[0070] The effective period is a time interval during which the reference signal received by the terminal device is valid. Understandably, the terminal device can determine the corresponding effective period from the received effective indication information.

[0071] In some embodiments, the effective indication information is used to indicate the effective time period configuration information from at least one effective time period configuration information.

[0072] Among them, the effective time period configuration information refers to the information used to configure the effective time period, that is, the information to configure the duration of the effective time period.

[0073] Optionally, the effective time period configuration information includes first effective time period configuration information and at least one second effective time period configuration information.

[0074] The first effective time period configuration information is used to indicate that all time periods after the receiving time of the effective indication information are effective time periods; the second effective time period configuration information includes a time length configuration value, which is used to indicate that the time period after the receiving time of the effective indication information with a time length configuration value is effective time period.

[0075] In this embodiment of the disclosure, the network device can flexibly configure the effective indication information and its corresponding effective time period according to the different terminal devices and network deployments, and can flexibly configure and select the effective time period configuration information.

[0076] In some embodiments, the activation indication information sent by the network device is used to indicate that a first effective time period configuration information has been selected. That is, the activation indication information sent by the network device indicates that all time periods after the time point at which the activation indication information is received by the terminal device are effective time periods. In this case, in some embodiments, the network device may also send failure indication information to the terminal device. The failure indication information indicates that the reference signal received by the terminal device during all time periods after the time point at which the failure indication information is received is invalid. That is, the reference signal received by the terminal device during all time periods after receiving the failure indication information is invalid.

[0077] Optionally, the effective indication information and / or the at least one effective time period configuration information are carried in the reference signal configuration information and sent to the terminal device.

[0078] As a first possible implementation, the network device sends reference signal configuration information carrying activation indication information to the terminal device.

[0079] As a second possible implementation, the network device sends reference signal configuration information carrying at least one effective time period configuration information to the terminal device.

[0080] As a third possible implementation, the network device sends reference signal configuration information to the terminal device, which carries effective indication information and at least one effective time period configuration information.

[0081] In some embodiments, the network device is configured with physical layer indication information, which carries activation indication information. The network device sends the activation indication information to the terminal device by sending the physical layer indication information. The physical layer indication information is configured by a higher layer.

[0082] In some embodiments, the network device is not configured with physical layer indication information, and the network device sends the effectiveness indication information by sending higher layer indication information carrying effectiveness indication information to the terminal device.

[0083] In some embodiments, the network device may also send window configuration information to the terminal device, the window configuration information being used to instruct the network device to stop sending reference signals within the window corresponding to the window configuration information, wherein the window is located within the effective time period.

[0084] In summary, by sending an activation indication message to a terminal device in a disconnected state through a network device, the activation indication message is used to indicate that the reference signal received by the terminal device within the activation time period corresponding to the activation indication message is effective. This allows the terminal device to receive the reference signal within the activation time period according to the configuration information, saving power and resources. The network device can also flexibly configure the activation time period to reduce system overhead.

[0085] This disclosure provides another method for indicating the effectiveness of a reference signal. Figure 3 This is a flowchart illustrating another method for indicating the effectiveness of a reference signal provided in an embodiment of this disclosure. This method can be executed by a network device. The method can be executed alone, or it can be executed together with any embodiment of this disclosure or any possible implementation in the embodiment, or it can be executed together with any technical solution in the related art.

[0086] like Figure 3 As shown, the method for indicating the activation of the reference signal may include the following steps: Step 301: Send at least one effective time period configuration information to the terminal device.

[0087] Optionally, at least one effective time period configuration information includes first effective time period configuration information and at least one second effective time period configuration information.

[0088] The first effective time period configuration information is used to indicate that all time periods after the receiving time of the effective indication information are effective time periods; the second effective time period configuration information includes a time length configuration value, which is used to indicate that the time period after the receiving time of the effective indication information with a time length configuration value is effective time period.

[0089] In some embodiments, at least one second effective time period configuration information includes at least one time length configuration value, which is related to the discontinuous reception (DRX) period of the terminal device. Optionally, at least one time length configuration value is {2n, 4n, 8n, 16n}, where n is the DRX period of the terminal device.

[0090] Understandably, the aforementioned DRX cycle can also be flexibly configured as needed.

[0091] It should be noted that, in this embodiment of the disclosure, the network device can flexibly configure the effective indication information and its corresponding effective time period according to the different terminal devices and network deployments, and can flexibly configure and select the effective time period configuration information.

[0092] Step 302: Send an activation indication message to the terminal device in a non-connected state. The activation indication message is used to indicate the activation time period configuration information selected from at least one activation time period configuration information.

[0093] The reference signal is either the synchronization signal block (SSB), the tracking reference signal (TRS), or the channel state information reference signal (CSI-RS).

[0094] In some embodiments, the activation indication information sent by the network device is used to indicate the selection of a first effective time period configuration information. That is, the activation indication information sent by the network device indicates that all time periods after the time point at which the activation indication information is received by the terminal device are effective time periods. In this case, in some embodiments, the network device sends failure indication information to the terminal device. The failure indication information indicates that the reference signal received by the terminal device during all time periods after the time point at which the failure indication information is received is invalid. In other words, the reference signal received by the terminal device during all time periods after receiving the failure indication information is invalid.

[0095] In some embodiments, the activation indication information sent by the network device is used to indicate the selection of at least one of the second activation time period configuration information. That is, the activation indication information sent by the network device indicates that the terminal device has a time period with a corresponding time length configuration value after the time point at which the activation indication information is received as the activation time period. For example, if the activation indication information indicates that a second activation time period configuration information 2n has been selected from at least one second activation time period configuration information {2n, 4n, 8n, 16n}, and the time length configuration value included is 2n, then the activation indication information indicates that the terminal device has a time period of 2n after the time point at which the activation indication information is received as the activation time period, where n is the DRX period of the terminal device.

[0096] Additionally, it should be noted that the effective time period configuration information in step 301 and the effective indication information in step 302 can be sent simultaneously in the reference signal configuration information, or they can be sent at different times. The signaling carrying the effective indication information can be higher-layer indication information or physical-layer indication information.

[0097] In some embodiments, the network device may also send window configuration information to the terminal device. This window configuration information instructs the network device to stop transmitting reference signals within a window corresponding to the configuration information, wherein the window is located within the effective time period. By configuring a window and stopping the transmission of reference signals within that window, the network device reduces its power consumption.

[0098] In summary, by sending at least one effective time period configuration information to a terminal device in a disconnected state, and sending an effective indication information to the terminal device in a disconnected state, the effective indication information is used to indicate the selection of the effective time period configuration information from the at least one effective time period configuration information, and to indicate that the reference signal received by the terminal device within the effective time period is effective. This allows the terminal device to receive the reference signal within the effective time period according to the configuration information, thereby saving power, reducing power consumption, conserving resources, and allowing network devices to flexibly configure the effective time period, reducing system overhead.

[0099] This disclosure provides another method for indicating the effectiveness of a reference signal. Figure 4 This is a flowchart illustrating another method for indicating the activation of a reference signal, provided in an embodiment of this disclosure. It should be noted that the method in this embodiment is executed by a terminal device.

[0100] like Figure 4 As shown, the method for indicating the effectiveness of the reference signal may include the following steps.

[0101] Step 401: Receive activation indication information. The activation indication information is used to indicate that the reference signal received by the terminal device during the activation time period corresponding to the activation indication information is effective. The terminal device is in a non-connected state.

[0102] In related technologies, a terminal device in a disconnected state can wake up when needed and perform time-frequency synchronization based on a received reference signal used for time-frequency tracking. For example, the terminal device wakes up before the Paging Occasion (PO) position to receive the reference signal for time-frequency synchronization. Optionally, the reference signal is a synchronization signal block (SSB), a tracking reference signal (TRS), or a channel state information reference signal (CSI-RS).

[0103] It should be noted that network devices can flexibly configure the reference signal used for time-frequency tracking, such as the time domain resources, frequency domain resources, period, window, etc. of the reference signal, or use a fixed pattern to indicate the above information of the reference signal.

[0104] Additionally, it should be noted that the effective indication information is information configured by the network device to indicate that the reference signal received by the terminal device is effective. In other words, the terminal device determines that the reference signal received within the effective time period corresponding to the effective indication information is effective based on the received effective indication information.

[0105] The effective period is a time interval during which the reference signal received by the terminal device is valid. Understandably, the terminal device can determine the corresponding effective period from the received effective indication information.

[0106] In some embodiments, the effective indication information is used to indicate the effective time period configuration information from at least one effective time period configuration information.

[0107] Among them, the effective time period configuration information refers to the information used to configure the effective time period, that is, the information to configure the duration of the effective time period.

[0108] Optionally, the effective time period configuration information includes first effective time period configuration information and at least one second effective time period configuration information.

[0109] The first effective time period configuration information is used to indicate that all time periods after the receiving time of the effective indication information are effective time periods; the second effective time period configuration information includes a time length configuration value, which is used to indicate that the time period after the receiving time of the effective indication information with a time length configuration value is effective time period.

[0110] In this embodiment of the disclosure, the network device can flexibly configure the effective indication information and its corresponding effective time period according to the different terminal devices and network deployments, and can flexibly configure and select the effective time period configuration information.

[0111] In some embodiments, the activation indication information sent by the network device is used to indicate that a first effective time period configuration information has been selected. That is, the activation indication information sent by the network device indicates that all time periods after the time point at which the activation indication information is received are effective time periods. In this case, in some embodiments, the network device sends failure indication information to the terminal device. The failure indication information indicates that the reference signal received by the terminal device during all time periods after the time point at which the failure indication information is received is invalid. That is, the reference signal received by the terminal device during all time periods after receiving the failure indication information is invalid.

[0112] Optionally, the effective indication information and / or the at least one effective time period configuration information are carried in the reference signal configuration information and received by the terminal device.

[0113] As a first possible implementation, the terminal device receives reference signal configuration information carrying activation indication information sent by the network device.

[0114] As a second possible implementation, the terminal device receives reference signal configuration information sent by the network device, which carries at least one effective time period configuration information.

[0115] As a third possible implementation, the terminal device receives reference signal configuration information sent by the network device, which carries effective indication information and at least one effective time period configuration information.

[0116] In some embodiments, the network device is configured with physical layer indication information, which carries activation indication information. The terminal device receives the activation indication information by receiving the physical layer indication information sent by the network device. The physical layer indication information is configured by a higher layer.

[0117] In some embodiments, the network device is not configured with physical layer indication information, and the terminal device receives the effectiveness indication information by receiving higher layer indication information carrying effectiveness indication information sent by the network device.

[0118] In some embodiments, the network device may also send window configuration information to the terminal device, the window configuration information being used to instruct the network device to stop sending reference signals within the window corresponding to the window configuration information, wherein the window is located within the effective time period.

[0119] In summary, by receiving the effective indication information, which is used to instruct the terminal device to take effect the reference signal received within the effective time period corresponding to the effective indication information, wherein the terminal device is in a disconnected state, the terminal device can receive the reference signal within the effective time period according to the configuration information, thereby saving power and resources. The network device can also flexibly configure the effective time period to reduce system overhead.

[0120] This disclosure provides another method for indicating the effectiveness of a reference signal. Figure 5 This is a flowchart illustrating another method for indicating the effectiveness of a reference signal provided in an embodiment of this disclosure. This method can be executed by a terminal device in a non-connected state. The method can be executed alone, or it can be executed together with any embodiment of this disclosure or any possible implementation in the embodiment, or it can be executed together with any technical solution in the related art.

[0121] like Figure 5 As shown, the method for indicating the activation of the reference signal may include the following steps: Step 501: Receive at least one effective time period configuration information.

[0122] Optionally, at least one effective time period configuration information includes first effective time period configuration information and at least one second effective time period configuration information.

[0123] The first effective time period configuration information is used to indicate that all time periods after the receiving time of the effective indication information are effective time periods; the second effective time period configuration information includes a time length configuration value, which is used to indicate that the time period after the receiving time of the effective indication information with a time length configuration value is effective time period.

[0124] In some embodiments, at least one second effective time period configuration information includes at least one time length configuration value, which is related to the discontinuous reception (DRX) period of the terminal device. Optionally, at least one time length configuration value is {2n, 4n, 8n, 16n}, where n is the DRX period of the terminal device.

[0125] Understandably, the aforementioned DRX cycle can also be flexibly configured as needed.

[0126] It should be noted that, in this embodiment of the disclosure, the network device can flexibly configure the effective indication information and its corresponding effective time period according to the different terminal devices and network deployments, and can flexibly configure and select the effective time period configuration information.

[0127] Step 502: Receive effective indication information, which is used to indicate the effective time period configuration information to select the effective time period from at least one effective time period configuration information.

[0128] The reference signal is either the synchronization signal block (SSB), the tracking reference signal (TRS), or the channel state information reference signal (CSI-RS).

[0129] In some embodiments, the activation indication information sent by the network device is used to indicate the selection of a first effective time period configuration information. That is, the activation indication information sent by the network device indicates that all time periods after the time point at which the activation indication information is received by the terminal device are effective time periods. In this case, in some embodiments, the network device sends failure indication information to the terminal device. The failure indication information indicates that the reference signal received by the terminal device during all time periods after the time point at which the failure indication information is received is invalid. In other words, the reference signal received by the terminal device during all time periods after receiving the failure indication information is invalid.

[0130] In some embodiments, the activation indication information received by the terminal device is used to indicate the selection of at least one of the second activation time period configuration information. That is, the terminal device determines, based on the received activation indication information, that the time period with a corresponding time length configuration value after the reception time of the activation indication information is the activation time period. For example, if the activation indication information indicates that a second activation time period configuration information 2n has been selected from at least one second activation time period configuration information {2n, 4n, 8n, 16n}, and the time length configuration value included is 2n, then the activation indication information indicates that the terminal device determines the time period 2n after the reception time of the activation indication information is the activation time period, where n is the DRX period of the terminal device.

[0131] Additionally, it should be noted that the effective time period configuration information in step 501 and the effective indication information in step 502 can be sent simultaneously in the reference signal configuration information, or they can be sent at different times. The signaling carrying the effective indication information can be higher-layer indication information or physical-layer indication information.

[0132] In some embodiments, the network device may also send window configuration information to the terminal device. This window configuration information instructs the network device to stop transmitting reference signals within a window corresponding to the configuration information, wherein the window is located within the effective time period. By configuring a window and stopping the transmission of reference signals within that window, the network device reduces its power consumption.

[0133] In summary, by receiving at least one effective time period configuration information and receiving effective indication information, the effective indication information is used to indicate the effective time period configuration information selected from the at least one effective time period configuration information, and to indicate that the reference signal received by the terminal device within the effective time period is effective. The terminal device is in a disconnected state, thereby enabling the terminal device to receive the reference signal within the effective time period according to the configuration information, saving power, reducing power consumption, and conserving resources. The network device can also flexibly configure the effective time period, reducing system overhead.
