[0019] Hereinafter, a reference signal configuration method according to an embodiment of the present application will be described in detail with reference to specific embodiments and application scenarios thereof in conjunction with the drawings.

[0020] 2 is a flow chart diagram of a reference signal configuration method according to an embodiment of the present application, which may be performed by a terminal, in other words, the method may be performed by software or hardware installed in the terminal. As shown in FIG. 2, the method may include the following steps:

[0021] In step S201, when the terminal is in an idle state or a deactivated state, a first configuration of a first reference signal and / or a first configuration state of the first configuration is determined, where the first configuration state includes at least one of: valid, available, activated, invalid, unavailable, and deactivated.

[0022] In the embodiment of the present application, when the terminal is in an idle state or a deactivated state, the terminal can determine the first configuration of the first reference signal in multiple ways, i.e., the terminal can determine the configuration to be used. The first configuration may be a received configuration, or a set of configurations selected from multiple sets of configurations that the first reference signal of the terminal already has.

[0023] The terminal may also determine a first configuration status of the first configuration, i.e., whether the first configuration is valid, available, or activated.

[0024] The first reference signal is a reference signal that the network configures for the UE in a connected state.

[0025] It should be noted that the connected UE and the idle / inactive UE here may be the same or different, i.e., the network may configure an idle / inactive terminal with a reference signal configuration that was configured when the terminal was in a connected state, and may configure this terminal with a reference signal configuration that was configured when other terminals were in a connected state, or a reference signal configuration that is not specific to a specific terminal and that was configured when the network was in a connected state.

[0026] The first reference signal includes at least one of a Channel State Information Reference Signal (CSI-RS), a Demodulation Reference Signal (DMRS), a Tracking Reference Signal (TRS), a Positioning Reference Signal (PRS), and a second synchronization and system information block (SSB), and the second synchronization and system information block is different from the first synchronization and system information block received by the terminal in an idle state. Thus, in the embodiment of the present application, when the terminal is in an idle state or an inactive state, the first configuration of the first reference signal and / or the first configuration state of the first configuration are determined, so that the idle / inactive terminal can use the reference signal in the connected state.

[0027] 3 is another flowchart of a reference signal configuration method according to an embodiment of the present application, which may be performed by a terminal, in other words, the method may be performed by software or hardware installed in the terminal. As shown in FIG. 3, the method may include the following steps:

[0028] In step S301, a radio resource control (RRC) is released from a connected state to the idle state, or suspended from a connected state to the deactivated state.

[0029] After the terminal transitions from a connected state to an idle state or a deactivated state, the terminal can determine a first configuration of a first reference signal and / or a first configuration state of the first configuration in a number of manners.

[0030] In step S302, when the terminal is in an idle state or a deactivated state, a first configuration of a first reference signal and / or a first configuration state of the first configuration is determined according to at least one of the following target indications:

[0031] Here, the target indication includes a pre-indication signal indication, a paging message indication, an RRC message indication, and a System Information (SI) indication.

[0032] It should be understood that the first reference signal is a reference signal that the network configures for the UE in a connected state, the first reference signal including at least one of a channel state information reference signal, a demodulation reference signal, a tracking reference signal, a positioning reference signal, and a second synchronization and system information block, and the second synchronization and system information block is different from the first synchronization and system information block received by the terminal in an idle state.

[0033] In one embodiment, the terminal can determine a first configuration of a first reference signal and / or a first configuration status of the first configuration according to an indication of the obtained advance indication signal, i.e., a bit in the advance indication signal indicates a validity, availability, or activation status of the first configuration of the first reference signal, or a bit in the advance indication signal indicates which set of configurations the first reference signal uses. The advance indication signal includes at least one of a Wake-Up Signaling (WUS), a Go-to-Sleep (GTS), a downlink control message scrambled by PS-RNTI (DCI with CRC scrambled by PS-RNTI, DCP), a paging response, a paging indication, and a paging early indication (PEI).

[0034] In another embodiment, the terminal can determine a first configuration of a first reference signal and / or a first configuration status of the first configuration according to the obtained paging message indication, i.e., a bit in the paging message indication indicates the validity, availability, or activation status of the first configuration of a first reference signal, or indicates which set of configurations the first reference signal uses. The paging message includes at least one of a downlink control message (paging DCI) corresponding to the paging message, a physical downlink control channel (paging PDCCH) corresponding to the paging message, a physical downlink shared channel (paging PDSCH) corresponding to the paging message, and a short message.

[0035] In another embodiment, the terminal can determine a first configuration of a first reference signal and / or a first configuration state of the first configuration by the obtained RRC message indication, i.e., a bit in an RRC message indicates a validity, availability, or activation state of the first configuration of a first reference signal, or indicates which configuration the first reference signal uses. The RRC message includes at least one of RRC release, RRC suspend, RRC configuration in a connected state, and RRC reconfiguration in a connected state.

[0036] In another embodiment, the terminal may determine the first constellation of the first reference signal and / or the first constellation status of the first constellation by the obtained SI message indication, i.e., a bit in the SI message indicates the validity, availability or activation status of the first constellation of the first reference signal or indicates which constellation the first reference signal uses.

[0037] In one embodiment, the target indication is further used to determine at least one of when the first configuration of the first reference signal is valid, when it is available, when it is activated, when it is disabled, when it is unavailable, and when it is deactivated.

[0038] In one embodiment, when the first configuration is a first reference signal configuration configured by a network side when in a connected state, the target indication is further used to indicate that a first configuration state of the first configuration is enabled. The target indication is used to indicate that a first configuration state configured by a network side for a terminal when in a connected state is continuously enabled, available or activated.

[0039] In one embodiment, a first deployment state of the first deployment is enabled from the time the targeting instruction is received.

[0040] In one embodiment, when the first reference signal has multiple sets of configurations, the terminal can determine the first configuration of the first reference signal from the multiple sets of configurations by a target indication. Specifically, the terminal indicates which set of configurations of the first reference signal to use or which set of configurations of the first reference signal are available, valid, or activated by a bit or bits in a target indication message.

[0041] The above-mentioned multiple sets of configuration information of the reference signal refer to a part or all of the parameters of the corresponding reference signal being configured with different values. For example, the configuration of the reference signal includes several parameters, and some or all of the parameters have multiple sets of different values.

[0042] Specifically, the above multiple set arrangement can be performed by one message, or multiple messages. When multiple messages perform multiple set arrangement, some messages may perform one set arrangement, and some messages may perform one or more sets arrangement.

[0043] In one embodiment, before determining the first constellation of the first reference signal, the method further comprises: Constraining at least one set of the first reference signals according to at least one of the following constraining manners: The arrangement method is: System messages and An advance directive signal; Paging messages (including paging DCI, paging PDSCH, short messages, etc.) RRC messages (including an RRC configuration message, an RRC reconfiguration message, an RRC Release message, and an RRC suspend message).

[0044] The RRC reconfiguration message includes at least one of a reconfiguration (ie, asynchronous reconfiguration), a handover command, a mobility control message, and a synchronous reconfiguration.

[0045] When configuration is performed by an RRC configuration or RRC reconfiguration message, it specifically refers to the configuration of reference signals performed for the terminal when the terminal is in a connected state, which can be continuously used by the terminal in an idle / inactive state according to the instruction of the network or the provisions of the protocol. When configuration is performed by an RRC release or RRC suspend message, it specifically refers to the configuration of reference signals performed for the terminal when the network releases the terminal to an idle state or suspends the terminal to an inactive state.

[0046] The first reference signal of the terminal has multiple sets of configurations, and may be configured by any one of the above configuration methods, or may be configured by one or more configuration methods. The multiple sets of configurations of the first reference signal refer to the configuration of parameter domains in some or all of the first reference signals having multiple configuration parameters. Transmitting, sending, and configuring the first reference signal to the terminal by the above method refers to transmitting, sending, and configuring resources of the first reference signal or resource group sets of the first reference signal to the terminal.

[0047] Therefore, in an embodiment of the present application, a first configuration of the first reference signal and / or a first configuration state of the first configuration is determined based on the acquired target indication, thereby enabling an idle / inactive terminal to use a reference signal in a connected state and flexibly configure it.

[0048] 4 is another flowchart of a reference signal configuration method according to an embodiment of the present application, which may be performed by a terminal, in other words, the method may be performed by software or hardware installed in the terminal. As shown in FIG. 4, the method may include the following steps:

[0049] In step S401, when the terminal is in an idle state or a deactivated state, a first configuration of a first reference signal and / or a first configuration state of the first configuration is determined, where the first configuration state of the first configuration is enabled from the time of receiving the first configuration of the first reference signal, where the first configuration state may be enabled, available, activated, disabled, unavailable, or deactivated.

[0050] It should be understood that the first reference signal is a reference signal that the network configures for the UE in a connected state, the first reference signal including at least one of a channel state information reference signal, a demodulation reference signal, a tracking reference signal, a positioning reference signal, and a second synchronization and system information block, and the second synchronization and system information block is different from the first synchronization and system information block received by the terminal in an idle state.

[0051] It should be understood that after acquiring the first configuration of the first reference signal, the terminal may set the first configuration status of the first configuration to valid / available / activated, or may set the first configuration status of the first configuration to invalid / unavailable / deactivated.

[0052] In one embodiment in which the first configuration state is valid / available / activated, if the first configuration of the first reference signal is performed by an RRC release or RRC suspend message, the first configuration state of the first configuration changes to valid / available / activated from the time of receiving the first configuration of the first reference signal.

[0053] In another embodiment, in which the first configuration state is valid / available / activated, the first configuration state of the first configuration is terminated when at least one of first conditions is satisfied after the terminal acquires the first configuration of a first reference signal. Specifically, the determined first configuration state of the first reference signal is continued until at least one of first conditions is satisfied.

[0054] The first condition is: a first preset timer times out, and the first deployment state is valid / available / activated until the first preset timer times out, where a threshold of the first preset timer may be defined by a network deployment or protocol; exceeding a first preset time length, the first deployment state being valid / available / activated until the duration of this state exceeds a first preset time length, where the first preset time length may be defined by a network deployment or protocol; Receiving a targeting instruction to indicate a first configuration state of a first configuration, the first configuration state including one of: valid / available / activated until the terminal receives a next targeting instruction to indicate that the first configuration state is valid / available / activated, or until the terminal receives a next targeting instruction to indicate that the first configuration state is invalid / unavailable / deactivated. The targeting instruction may be the same as the targeting instruction recorded in step S302 of FIG. 3, or may adopt other instructions; A second configuration of the first reference signal is received, the second configuration being partially or completely different from the first configuration, e.g., the first reference signal has some parameters and the second configuration has values ​​that are different from some or all of the parameters of the first configuration, and the first configuration state is valid / available / activated until the terminal acquires a new configuration of the first reference signal.

[0055] In one embodiment in which the first configuration state is disabled / unavailable / deactivated, if the first configuration of the first reference signal is performed by an RRC release or RRC suspend message, the first configuration state of the first configuration changes to disabled / unavailable / deactivated from the time of receiving the first configuration of the first reference signal.

[0056] In another embodiment, in which the first configuration state is disabled / unavailable / deactivated, the first configuration state of the first configuration is terminated when the terminal satisfies at least one of first conditions after receiving a first configuration of a first reference signal.

[0057] The first condition is: a first preset timer times out, and the first deployment state is disabled / unavailable / deactivated until the first preset timer times out, where a threshold of the first preset timer may be defined by a network deployment or protocol; exceeding a first preset amount of time, the first deployment state being disabled / unavailable / deactivated until the first preset amount of time is exceeded, where the first preset amount of time may be defined by a network deployment or protocol; Receiving a targeting instruction to indicate a first configuration state of a first configuration, the first configuration state including any one of: being disabled / unavailable / deactivated until the terminal receives a next targeting instruction to indicate that the first configuration state is valid / available / activated, or being disabled / unavailable / deactivated until the terminal receives a next targeting instruction to indicate that the first configuration state is invalid / unavailable / deactivated. The targeting instruction may be the same as the targeting instruction recorded in step S302 of FIG. 3, or may adopt other instructions.

[0058] A second configuration of the first reference signal is received, the second configuration being partially or completely different from the first configuration, and the first configuration state is invalid / unavailable / deactivated until the terminal receives a new configuration of the first reference signal.

[0059] In the process of the first reference signal transitioning from using the first constellation to using the second constellation, in one embodiment, the terminal may replace all the first constellation of the first reference signal with the second constellation. If the parameter X in the first reference signal is configured in two sets of constellations, which are Xa in the first constellation and Xb in the second constellation, respectively, the parameter X needs to be replaced from Xa to Xb. If the parameter Y of the first reference signal is configured as Ya only in the first constellation and not configured in the second constellation, the constellation of the parameter Y does not exist in the first reference signal after the transformation. If the parameter Z is not configured in the first constellation and is configured as Zb in the second constellation, the parameter Z is configured as Zb after the transformation.

[0060] In another embodiment, the first constellation of the first reference signal may be partially replaced by the second constellation. If the parameter X in the first reference signal is arranged in two sets of constellations, Xa in the first constellation and Xb in the second constellation, then the parameter X needs to be replaced from Xa to Xb. If the parameter Y of the first reference signal is arranged as Ya only in the first constellation and not arranged in the second constellation, then the parameter Y continues to be arranged as Ya in the transformed first reference signal. If the parameter Z is not arranged in the first constellation and is arranged as Zb in the second constellation, then the parameter Z is arranged as Zb after the transformation.

[0061] As a result, in the embodiment of the present application, the first configuration state of the first configuration is enabled from the time when the first configuration of the first reference signal is received, so that an idle / inactive terminal can use a reference signal in a connected state and flexibly perform configuration, thereby achieving the purpose of energy saving.

[0062] 5 is another flowchart of a reference signal configuration method according to an embodiment of the present application, which may be performed by a terminal, in other words, the method may be performed by software or hardware installed in the terminal. As shown in FIG. 5, the method may include the following steps:

[0063] In step S501, when the terminal is in an idle state or a deactivated state, determine a first constellation of a first reference signal and / or a first constellation state of the first constellation.

[0064] The first configuration of the first reference signal is a configuration of the first reference signal performed by the network side when the terminal is in an RRC connected state.

[0065] In step S502, when the terminal is released to an idle state or suspended to a deactivation state, a first configuration state of the first configuration is enabled.

[0066] It should be understood that the first reference signal is a reference signal that the network configures for the UE in a connected state, the first reference signal including at least one of a channel state information reference signal, a demodulation reference signal, a tracking reference signal, a positioning reference signal, and a second synchronization and system information block, and the second synchronization and system information block is different from the first synchronization and system information block received by the terminal in an idle state.

[0067] In one embodiment, if a first configuration of a first reference signal is configured by the network side to the terminal when the terminal is in a connected state, a first configuration state of the first configuration is activated when the terminal is released to an idle state or suspended to a deactivated state, where the first configuration state may be valid / available / activated or invalid / unavailable / deactivated.

[0068] In one embodiment, if the first configuration of the first reference signal is configured by the network side to the terminal when the terminal is in a connected state, when the terminal is released to an idle state or suspended to a deactivated state, the first configuration state of the first configuration continues to be enabled / available / activated, or when the terminal is released to an idle state or suspended to a deactivated state, the enabled / available / activated first configuration state of the first configuration ends when at least one of the second conditions is satisfied.

[0069] Here, the second condition is: a second preset timer times out, and the first deployment state is valid / available / activated until the second preset timer times out, where a threshold of the second preset timer may be defined by a network deployment or protocol; exceeding a second preset time period, the first deployment state being valid / available / activated until the duration of this state exceeds a second preset time period, where the second preset time period may be defined by a network deployment or protocol; Receiving a targeting instruction to indicate a first configuration state of the first configuration, the first configuration state including any one of: valid / available / activated until the terminal receives a next targeting instruction to indicate that the first configuration state is valid / available / activated, or until the terminal receives a next targeting instruction to indicate that the first configuration state is invalid / unavailable / deactivated. The targeting instruction may be the same as the targeting instruction recorded in step S302 of FIG. 3, or may adopt other instructions.

[0070] A second configuration of the first reference signal is received, the second configuration being partially or completely different from the first configuration, and the first configuration state is valid / available / activated until the terminal receives a new configuration of the first reference signal.

[0071] In another embodiment, if the first configuration of the first reference signal is configured by the network side to the terminal when the terminal is in a connected state, when the terminal is released to an idle state or suspended to a deactivated state, the first configuration state of the first configuration continues to be disabled / unavailable / deactivated, or when the terminal is released to an idle state or suspended to a deactivated state, the disabled / unavailable / deactivated first configuration state of the first configuration ends when at least one of the second conditions is satisfied.

[0072] Here, the second condition is: a second preset timer times out, and the first deployment state is disabled / unavailable / deactivated until the second preset timer times out, where a threshold of the second preset timer may be specified by a network deployment or protocol; exceeding a second preset amount of time, the first deployment state being disabled / unavailable / deactivated until the second preset amount of time is exceeded, where the second preset amount of time may be defined by a network deployment or protocol; Receiving a targeting instruction to indicate a first configuration state of the first configuration, the first configuration state including any one of: being disabled / unavailable / deactivated until the terminal receives a next targeting instruction to indicate that the first configuration state is valid / available / activated, or being disabled / unavailable / deactivated until the terminal receives a next targeting instruction to indicate that the first configuration state is invalid / unavailable / deactivated. The targeting instruction may be the same as the targeting instruction recorded in step S302 of FIG. 3, or may adopt other instructions.

[0073] A second configuration of the first reference signal is received, the second configuration being partially or completely different from the first configuration, and the first configuration state is invalid / unavailable / deactivated until the terminal acquires a new configuration of the first reference signal.

[0074] Therefore, in an embodiment of the present application, if the first configuration of the first reference signal is a configuration of the first reference signal performed by the network side when the terminal is in an RRC connected state, when the terminal is released to an idle state or suspended to an inactive state, the first configuration state of the first configuration is enabled, so that the idle / inactive terminal can use the reference signal in the connected state and perform configuration flexibly, thereby achieving the purpose of energy saving.

[0075] It should be noted that the reference signal configuration method provided by the embodiment of the present application may be implemented by a reference signal configuration device, or may be implemented by a control module for implementing the reference signal configuration method in the reference signal configuration device. In the embodiment of the present application, the reference signal configuration device according to the embodiment of the present application is described by taking the reference signal configuration device implementing the reference signal configuration method as an example.

[0076] FIG. 6 is a structural schematic diagram of a reference signal configuration device according to an embodiment of the present application. As shown in FIG.

[0077] The configuration module 601 is used to determine a first configuration of a first reference signal and / or a first configuration state of the first configuration when the terminal is in an idle state or a deactivated state, where the first configuration state includes at least one of: valid, available, activated, invalid, unavailable, and deactivated.

[0078] Optionally, the configuration module 601 may include a first configuration unit for determining a first configuration of a first reference signal when the terminal is in an idle state or a deactivated state, and a second configuration unit is used to determine a first configuration state of the first configuration when the terminal is in an idle state or a deactivated state.

[0079] As a result, in an embodiment of the present application, an idle / inactive terminal can use a reference signal in a connected state by determining a first configuration of a first reference signal and / or a first configuration state of the first configuration when the terminal is in an idle state or an inactive state.

[0080] Furthermore, the device The radio resource control (RRC) further includes a state module for releasing from a radio resource control (RRC) connected state to the idle state or suspending from a radio resource control (RRC) connected state to the deactivated state.

[0081] Further, the configuration module is used to determine a first configuration of a first reference signal and / or a first configuration state of the first configuration by at least one of the following target indications when the terminal is in an idle state or a deactivated state:

[0082] Here, the target indication includes a pre-indication signal indication, a paging message indication, an RRC message indication, and a system information indication.

[0083] Furthermore, the pre-indication signal includes at least one of a wake-up signal, a sleep signal, a paging response, a paging indication, and a paging pre-indication; or The paging message includes at least one of a PDCCH corresponding to the paging message, a PDSCH physical downlink shared channel corresponding to the paging message, and a short message; or The RRC message includes at least one of RRC release, RRC suspend, RRC configuration in connected state, and RRC reconfiguration in connected state.

[0084] Additionally, the target indication is also used to determine at least one of when the first configuration of the first reference signal is valid, when it becomes available, when it is activated, when it becomes invalid, when it becomes unavailable, and when it is deactivated.

[0085] Furthermore, when the first configuration is a first reference signal configuration configured by the network side when in a connected state, the target indication is further used to indicate that the first configuration state of the first configuration is enabled.
