[0031] Figure 1This diagram illustrates a block diagram of a wireless communication system applicable to embodiments of this application. The wireless communication system includes a terminal 11 and a network-side device 12. Terminal 11 can be a mobile phone, tablet computer, laptop computer, personal digital assistant (PDA), handheld computer, netbook, ultra-mobile personal computer (UMPC), mobile internet device (MID), augmented reality (AR) / virtual reality (VR) device, robot, wearable device, vehicle-mounted device (VUE), pedestrian terminal (PUE), smart home (home devices with wireless communication capabilities, such as refrigerators, televisions, washing machines, or furniture), game console, personal computer (PC), ATM, or self-service machine, etc. Wearable devices include: smartwatches, smart bracelets, smart headphones, smart glasses, smart jewelry (smart bracelets, smart chains, smart rings, smart necklaces, smart anklets, smart anklets, etc.), smart wristbands, smart clothing, etc. It should be noted that the specific type of terminal 11 is not limited in this embodiment.

The base station is not limited to specific technical terms. It should be noted that in this application embodiment, only a base station in an NR system is used as an example for description, and the specific type of base station is not limited.

[0032] UEs operating in idle / inactive states require automatic gain control (AGC) and time-frequency synchronization before receiving paging messages to ensure correct reception of the physical downlink control channel (PDCCH) / physical downlink shared channel (PDSCH). In NR, synchronization signal blocks (SSBs) are used to perform AGC and time-frequency synchronization in the idle / inactive state. However, SSB transmission periods are typically long (e.g., 20ms), requiring the UE to wake up earlier before receiving paging messages. Furthermore, the UE may need to receive multiple SSBs for synchronization and AGC, resulting in significant energy consumption for SSB reception.

[0033] In related technologies, Channel State Information (CSI)-Reference Signal (RS) can be used for synchronization, CSI measurement, Radio Resource Management (RRM) measurement, radio link monitoring, beam failure detection, beam management, AGC, etc., in connected mode. However, UEs in idle / inactive mode cannot use CSI-RS to perform these functions. Therefore, to reduce power consumption, Tracking Reference Signal (TRS) / CSI-RS is introduced in the Radio Resource Control (RRC) idle / inactive mode to assist in measurement, thereby reducing power consumption and achieving energy saving.

[0034] Since a TRS consists of four CSI-RS resources and has a larger bandwidth, it provides better time-frequency tracking compared to SSBs. When a TRS is available in the idle / inactive state, the UE can skip multiple SSBs if it uses the TRS for synchronization before receiving a paging opportunity (PO) under low signal-to-noise ratio conditions. Conversely, if a TRS is unavailable in the idle / inactive state, the UE needs to use three SSBs for AGC, synchronization, and RRM measurements before the paging opportunity (PO), requiring more than 40ms to wake up in advance. However, when a TRS is available in the idle / inactive state, assuming the UE only needs one TRS and one SSB for AGC and synchronization before receiving a paging opportunity, and given that the TRS configuration is generally more intensive than the SSB configuration, the UE needs to wake up less than 40ms in advance, resulting in energy savings.

[0035] In related technologies, a System Information Block (SIB) is introduced to carry the configuration of idle / inactive TRS / CSI-RS occasion(s). The configuration information of TRS / CSI-RS occasion(s) contains one or more TRS resource sets, and each TRS resource set contains a set of TRS resources.

[0036] Regarding the availability of idle / inactive UEs, it has been agreed to support paging PDCCH based availability indication information and PEI based availability indication information. For paging PDCCH based L1 availability indication, when the availability indication information is received, the availability takes effect for a period of time from the reference point. This period of time is called the validity duration. The duration of the validity duration can be configured by the higher layer. The reference point for the start of the validity duration is the system frame number (SFN) of the first paging frame (PF) in the default discontinuous reception cycle (DRXcycle) in which the UE receives the availability indication information. The duration of the validity duration is based on the default paging cycle, and the available values ​​are {1,2,4,8,16,32,

[64] ,

[128] ,

[256] ,

[512] }. When the higher layer does not configure the duration of the validity duration, the UE assumes that the duration of the validity duration is 2 default paging cycles(s).

[0037] The modification period is used to update SI messages other than those related to Earthquake and Tsunami Warning System (ETWS), Commercial Mobile Early Warning System (CMAS), and Location Assisted Data (MADS). It applies to UEs configured with DRXcycle. If an SI message changes within a modification period, the network side will include the SI change indication information in the paging of the current modification period and broadcast the updated system information in the next modification period.

[0038] The boundary calculation method is as follows:

[0039] SFN mod m = 0; where m is the number of radio frames constituting the modification period, configured by the system information.

[0040] After the UE receives the idle / inactive TRS / CSI-RS availability indication, the UE assumes that the idle / inactive TRS / CSI-RS is valid for the effective duration starting from the reference point. However, one scenario is that the configuration information carrying the idle / inactive TRS / CSI-RS occasion(s) or the duration of the effective duration may change during the effective duration. When this happens, it is unclear how the UE handles the validity of the idle / inactive TRS / CSI-RS.

[0041] This application provides a method, apparatus, and terminal for determining the effective duration of a reference signal, which can determine the effective duration of a first reference signal and detect the first reference signal during the effective duration.

[0042] The method for determining the effective duration of the 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.

[0043] This application provides a method for determining the effective duration of a reference signal, such as... Figure 2 As shown, it includes:

[0044] Step 101: In the idle or inactive state, the terminal obtains the first information;

[0045] Step 102: The terminal determines the target effective duration of the first reference signal based on the first information, or determines that the first reference signal is unavailable based on the second availability indication information. The first reference signal includes a tracking reference signal and / or a channel state information reference signal.

[0046] The first information includes at least one of the following: system information message, first availability indication information, and second availability indication information;

[0047] The first availability indication information is the availability indication information of the first reference signal in the downlink control message, and the second availability indication information is the availability indication information of the first reference signal received during the change period of receiving system information change indication information containing configuration information of the first reference signal.

[0048] In the embodiments of this application, in the idle state or the inactive state, the terminal determines the effective duration of the first reference signal in the idle state and / or the inactive state according to the first information. Then, the terminal can detect the first reference signal within the effective duration of the first reference signal. Even if the configuration information of the first reference signal changes after the terminal receives the availability indication information of the first reference signal, the terminal's behavior can still be clearly defined.

[0049] In some embodiments, the terminal determines the target effective duration of the first reference signal based on the first information, including:

[0050] The terminal determines the end time of the target's effective duration as a first time, which is determined by the expiration time of the first effective duration and a second time.

[0051] The second time includes any of the following:

[0052] The time unit in which the boundary of the change period in which the terminal receives the system information (SI) message;

[0053] The terminal receives the Nth change cycle after the change cycle in which the first system information message is received;

[0054] The system frame number (SFN) of the first paging frame (PF) in the time unit in which the terminal receives the first system information message or in the default discontinuous reception (DRX) cycle in which it is located;

[0055] The system information block 1 is located in the time unit where the terminal receives the updated system information block 1 or in the system frame number of the first paging frame in the default discontinuous reception period. The system information block 1 indicates that the configuration information of the first reference signal has been changed.

[0056] The system frame number of the first paging frame in the Mth discontinuous reception cycle after the default discontinuous reception cycle in which the terminal receives the first system information message;

[0057] The terminal receives the first system information message at the Pth time unit after the time unit in which the first system information message is received.

[0058] The first system information message carries configuration information for the updated first reference signal, and the time unit includes system frame number, subframe, time slot and symbol, where M, N and P are positive integers.

[0059] In the above embodiments, the first time is the time when the duration of the first effective duration expires and the earlier time in the second time; or

[0060] The first time is the time when the duration of the first valid duration expires; or

[0061] The first time is the second time.

[0062] The first SI message is a system information block (SIB) message containing configuration information of the first reference signal in the idle state and / or inactive state.

[0063] In some embodiments, the configuration information of the first reference signal includes at least one of the following:

[0064] The duration of the effective period of the first reference signal;

[0065] Configuration information regarding the timing of the first reference signal.

[0066] The timing configuration information of the first reference signal includes at least one resource set of at least one first reference signal, and the resource set includes at least one of the following parameters:

[0067] TRS-ResourceSetId is the identifier for the tracking reference signal resource set.

[0068] Frequency domain allocation information;

[0069] Number of time slots (numofslot);

[0070] Starting Resource Block (startingRB);

[0071] Number of resource blocks: nrofRBs;

[0075] Quasi-co-address information, such as SSB-index;

[0076] The availability indicator ID of the first reference signal corresponding to the resource set of the first reference signal is indBitID;

[0077] Scrambling ID.

[0078] In some embodiments, the terminal determines the effective duration of the first reference signal based on second availability indication information, including:

[0079] The terminal determines that the first reference signal is unavailable.

[0080] For example, under certain circumstances, the UE ignores the availability indication information of the received idle and / or inactive first reference signal; specifically, if the UE receives the availability indication information of the idle and / or inactive first reference signal under certain circumstances, it still considers the idle and / or inactive first reference signal to be unavailable.

[0081] In some embodiments, the terminal determining the target effective duration of the first reference signal based on the first information, or determining that the first reference signal is unavailable based on the second availability indication information, further includes:

[0082] Based on the received first indication information, perform the step of determining the target effective duration of the first reference signal, or perform the step of determining that the first reference signal is unavailable based on the second availability indication information.

[0083] The first indication information indicates to the terminal how to determine the effective duration of the first reference signal. For example, when the first indication information is true, the first reference signal is determined to be unavailable based on the received first indication information; when the first indication information is false, the start time of the effective duration is determined to be the first start time and the end time is determined to be the first time based on the received first indication information.

[0084] Of course, it is also possible that when the first indication information is false, the first reference signal is determined to be unavailable based on the received first indication information; when the first indication information is true, the start time of the effective duration period is determined as the first start time and the end time is determined as the first time based on the received first indication information.

[0085] In some embodiments, the system information message includes configuration information of a first reference signal, and the terminal determines the target effective duration of the first reference signal based on the first information, including:

[0086] The terminal determines the effective duration of the first reference signal based on changes to the configuration information of the first reference signal.

[0087] The changes to the configuration information of the first reference signal include at least one of the following:

[0088] The duration of the effective duration of the first reference signal is changed from the duration of the first effective duration to the duration of the second effective duration;

[0089] The timing configuration information of the first reference signal has been changed;

[0090] At least one parameter in the first reference signal resource set during the timing of the first reference signal is changed.

[0091] In some embodiments, the terminal determines the effective duration of the first reference signal based on changes in the configuration information of the first reference signal, including any of the following:

[0092] If at least one parameter in the first reference signal resource set changes during the timing of the first reference signal, and the configuration information of the first reference signal applied by the terminal does not change, the start time of the effective duration of the first reference signal is determined as the first start time, and the end time is determined as the third time.

[0093] If at least one parameter in the first reference signal resource set changes during the timing of the first reference signal, and the configuration information of the first reference signal applied by the terminal changes, the start time of the effective duration of the first reference signal is determined as the first start time, and the end time is determined as the third time.

[0094] If the duration of the effective duration of the first reference signal is changed to the duration of the second effective duration, the effective duration of the first reference signal is restarted, or the duration of the second effective duration is applied.

[0095] Wherein, the first start time is the time when the terminal receives the first availability indication information;

[0096] The third time is any one of the following:

[0097] The first is the time when the duration of the first valid duration expires;

[0098] The second is the system frame number of the first paging frame in the default discontinuous reception cycle in which the availability indication information of the next first reference signal received by the terminal is located;

[0099] The one that comes first between the first and the second.

[0100] In the above embodiments, the effective duration of restarting the first reference signal includes:

[0101] The start time of the effective duration period is the second time, and the end time is the time when the duration of the second effective duration period expires.

[0102] In the above embodiments, the duration of the second effective duration includes:

[0103] The effective duration begins at the second time and ends at the fifth time.

[0104] The fifth time includes any of the following:

[0105] The first is the system frame number of the first paging frame in the default discontinuous reception cycle in which the availability indication information of the next first reference signal is received;

[0106] The second is the system frame number of the first remaining valid duration period that has expired and / or the system frame number of the first paging frame in the default discontinuous reception period.

[0107] The one that comes first between the first and the second.

[0108] The duration of the first remaining valid duration period is obtained by subtracting the duration of the third valid duration period from the duration of the second valid duration period. The duration of the third valid duration period is the time length between the second time and the first start time.

[0109] In some embodiments, if the end time is the system frame number whose duration has expired for the first remaining valid duration and / or the system frame number of the first paging frame in the default discontinuous reception period:

[0110] If the duration of the remaining valid duration is less than 0, the first reference signal is determined to be invalid from the second time.

[0111] If the duration of the remaining valid duration is not less than 0, the first reference signal is valid within the time range of the remaining valid duration.

[0112] In some embodiments, the terminal determining the target effective duration of the first reference signal based on the second available indication information includes:

[0113] If the second available indication information indicates that all tracking reference signals and / or channel state information reference signals configured in the network are invalid, the end time of the effective duration of the target is determined to be any one of the following:

[0114] The terminal receives the second availability indication information at the time unit where the boundary of the associated change period is located.

[0115] The terminal receives the time unit of the Ath subsequent change period of the change period in which the second availability indication information is located or associated.

[0116] The system frame number of the first paging frame in the time unit in which the terminal receives the second availability indication information or in the default discontinuous reception period in which it is located.

[0117] The system frame number of the first paging frame in the B discontinuous reception cycles following the default discontinuous reception cycle in which the terminal receives the second availability indication information;

[0118] The time unit includes a system frame number, subframe, time slot, and symbol, where A and B are positive integers, and all tracking reference signals and / or channel state information reference signals include the first reference signal.

[0119] In some embodiments, the terminal determining the target effective duration of the first reference signal based on the first available indication information includes:

[0120] When the first availability indication information indicates that one or more of the resources or resource sets of the first reference signal are valid, the start time of the target valid duration period is determined as the sixth time; the end time is the time when the duration of the first valid duration period expires or the duration of the second remaining valid duration period, the duration of the second remaining valid duration period is equal to the duration of the first valid duration period minus T, where T is the duration between the sixth time and the time when the terminal receives the first availability indication information, and the sixth time is the time when the terminal receives the second availability indication information.

[0121] In one specific embodiment, the effective duration of the first reference signal in the idle state and / or inactive state ends at the system frame number where the modification period boundary is located. For example... Figure 3 As shown, this embodiment includes the following steps:

[0122] Step 1: At time T1, the UE receives the paging PDCCH, which carries the System Information Change (SI change) indication information;

[0123] Step 2: At time T2, the UE receives a paging PDCCH, which carries availability indication information of the first reference signal in the idle state and / or inactive state;

[0124] Step 3: The UE determines the effective duration based on the availability indication information of the first reference signal in the idle state and / or inactive state: its start time is the SFN where the first PF is located in the default DRX cycle at time T2, and the duration is the effective duration configured in the current system information;

[0125] Step 4: During the effective duration, the UE detects the first reference signal of the idle state and / or inactive state according to the configuration information of the first reference signal of the idle state and / or inactive state;

[0126] Step 5: The UE receives the updated SIB-X at time T3, which carries the configuration information of the updated idle state and / or inactive state first reference signal;

[0127] Step 6: The UE considers that the first reference signal of the idle state and / or inactive state is no longer available starting from the SFN where the boundary of the change period is located at time T3;

[0128] Step 7: At time T4, the UE receives availability indication information for the tracking reference signal in the idle state and / or inactive state. The UE determines the effective duration of the first reference signal in the idle state and / or inactive state: the UE considers the start time to be the SFN where the first PF is located in the default DRX cycle at time T4, and the duration to be the effective duration length configured in the current system information at time T4.

[0129] Step 8: During the effective duration, the UE detects the first reference signal of the idle state and / or inactive state according to the configuration information of the updated first reference signal of the idle state and / or inactive state received at time T3.

[0130] In another specific embodiment, the terminal ignores the availability indication information of the first reference signal in the idle state and / or inactive state. This embodiment includes the following steps:

[0131] Step 1: At time T1, the UE receives the paging PDCCH, which carries system information change indication information;

[0132] Step 2: At time T2, the UE receives a paging PDCCH, which carries availability indication information of the first reference signal in the idle state and / or inactive state;

[0133] Step 3: The UE ignores the availability indication information of the first reference signal in the idle state and / or inactive state, that is, the UE still considers the first reference signal in the idle state and / or inactive state to be invalid.

[0134] In another specific embodiment, the UE determines the availability of the first reference signal in the idle state and / or inactive state based on the first indication information. If the first indication information is set to true, it means that if the UE receives the availability indication information of the first reference signal in the idle state and / or inactive state during the modification period for receiving system information change indication information, the UE ignores the availability indication information. If the first indication information is set to false, it means that if the UE discovers a configuration information change of the first reference signal in the idle state and / or inactive state during the effective duration, the first reference signal in the idle state and / or inactive state will no longer be available until the SFN at the boundary of the modification period where the new configuration information is received. This embodiment includes the following steps:

[0135] Step 1: The UE receives the first indication information and sets it to true;

[0136] Step 2: At time T1, the UE receives the paging PDCCH, which carries system information change indication information;

[0137] Step 3: At time T2, the UE receives a paging PDCCH, which carries availability indication information of the first reference signal in the idle state and / or inactive state;

[0138] Step 4: The UE ignores the availability indication information of the first reference signal in the idle state and / or inactive state, that is, the UE still considers the first reference signal in the idle state and / or inactive state to be invalid.

[0139] In another specific embodiment, the configuration information of the first reference signal timing (occasion(s)) of the idle state and / or inactive state of the UE application remains unchanged. This embodiment includes the following steps:

[0140] Step 1: At time T1, the UE receives the paging PDCCH, which carries system information change indication information;

[0141] Step 2: At time T2, the UE receives a paging PDCCH, which carries availability indication information of the first reference signal in the idle state and / or inactive state;

[0142] Step 3: The UE determines the effective duration based on the availability indication information of the first reference signal in the idle state and / or inactive state: its start time is the SFN where the first PF is located in the default DRX cycle at time T2, and the duration is the effective duration configured in the current system information;

[0143] Step 4: During the effective duration, the UE detects the first reference signal of the idle state and / or inactive state according to the configuration information of the first reference signal of the idle state and / or inactive state;

[0144] Step 5: At time T3, the UE receives the updated SIB-X, which carries the updated configuration information of the first reference signal for the idle state and / or inactive state; the UE finds that the configuration information of the first reference signal for the idle state and / or inactive state it is using has not changed;

[0145] Step 6: The UE assumes that the first reference signal for the idle state and / or inactive state is valid until the earlier of the following two times: C and D:

[0146] C: Before receiving availability indication information from the first reference signal of the next idle state and / or inactive state;

[0147] D: Before the expiration of the effective duration of the first reference signal in the idle state and / or inactive state.

[0148] Step 7: If the UE receives availability indication information for the first reference signal in the idle state and / or inactive state, the UE determines the availability of the first reference signal in the idle state and / or inactive state after the SFN where the first PF is located in the default DRX cycle of the indication information based on the availability indication information.

[0149] In another specific embodiment, the configuration information of the first reference signal occurrence(s) of the idle state and / or inactive state of the UE application is changed, such as... Figure 4 As shown, this embodiment includes the following steps:

[0150] Step 1: At time T1, the UE receives the paging PDCCH, which carries system information change indication information;

[0151] Step 2: At time T2, the UE receives a paging PDCCH, which carries availability indication information of the first reference signal in the idle state and / or inactive state;

[0152] Step 3: The UE determines the effective duration based on the availability indication information of the first reference signal in the idle state and / or inactive state: its start time is the SFN where the first PF is located in the default DRX cycle at time T2, and the duration is the effective duration configured in the current system information;

[0153] Step 4: During the effective duration, the UE detects the first reference signal of the idle state and / or inactive state according to the configuration information of the first reference signal of the idle state and / or inactive state;

[0154] Step 5: At time T3, the UE receives the updated SIB-X, which carries the updated configuration information of the first reference signal for the idle state and / or inactive state; the UE discovers that the configuration information of the first reference signal for the idle state and / or inactive state it is applying has been changed;

[0155] Step 6: The terminal determines the following second and third valid duration periods. The second valid duration period begins at the SFN of the first PF in the default DRX cycle where the UE receives the availability indication information of the first reference signal in the idle state and / or inactive state, and ends at the SFN of the boundary of the modification period where the UE receives updated system information. The third valid duration period begins at the SFN of the boundary of the modification period where the UE receives updated system information, and ends at the earlier of the following times: the UE receives the availability indication information of the new first reference signal in the idle state and / or inactive state, and the first valid duration period expires. Figure 4 As shown;

[0156] Step 7: The UE applies the configuration information of the first TRS / CSI-RS (i.e., the configuration information before the change) during the second valid duration period; and applies the configuration information of the second TRS / CSI-RS (i.e., the configuration information after the change) during the third valid duration period.

[0157] In another specific embodiment, the validity period of the first reference signal for the idle state and / or inactive state of the UE application has been updated, such as... Figure 5 As shown, this embodiment includes the following steps:

[0158] Step 1: The UE receives availability indication information of the first reference signal in the idle state and / or inactive state at T1;

[0159] Step 2: The UE determines the effective duration length, such as... Figure 5 The “original effective duration” shown refers to the SFN where the first PF in the default DRX cycle of T1 is located, with the length of the effective duration configured on the network side.

[0160] Step 3: The UE receives the SI change indication information at time T2;

[0161] Step 4: The UE receives the updated SI at time T3, which carries the length of the updated effective duration.

[0162] Step 5: The UE takes the SFN where the boundary of the modification period at time T3 is located as the starting point, and the length of the updated valid duration period as the remaining valid duration period length, to determine the "current valid duration period length".

[0163] Step 6: Within the current valid duration, the UE considers the first reference signal of the idle state and / or inactive state to be valid.
