DETAILED DESCRIPTION OF THE INVENTION

However, in the following description, a New Radio (NR) system will be described for illustrative purposes, and NR terminology will be used in most of the following description, but these technologies can be applied to systems other than NR systems, for example, 6th generation (6G) systems. th It can also be applied to 6G (Generation, 6G) communication systems.

[0018] 1 is a block diagram of a wireless communication system to which the present invention can be applied. The wireless communication system includes a terminal 11 and a network side device 12. Here, the terminal 11 may be a terminal-side device such as a mobile phone, a tablet computer (Tablet Personal Computer), a laptop computer (also called a notebook computer), a personal digital assistant (PDA), a personal digital assistant (PDA), a netbook, an ultra-mobile personal computer (UMPC), a mobile internet device (MID), an augmented reality (AR) / virtual reality (VR) device, a robot, a wearable device, a vehicle-mounted equipment (VUE), a pedestrian-mounted equipment (PUE), a smart home (home equipment with wireless communication functions such as a refrigerator, a television, a washing machine, or furniture), a game console, a personal computer (PC), an automated teller machine, or a kiosk terminal, and wearable devices include a smart watch, a smart band, a smart earphone, a smart glass, a smart accessory (smart bracelet, smart wristband, smart ring, smart necklace, smart anklet, smart ankle accessory, etc.), a smart wristband, a smart clothing, etc. It should be noted that the embodiments of the present application are not limited to a specific type of the terminal 11. The network side equipment 12 may include access network equipment or core network equipment, where the access network equipment may also be referred to as radio access network equipment, radio access network (RAN), radio access network function or radio access network unit.The access network equipment 12 may include a base station, a WLAN access point, a WiFi node, or the like. The base station may be referred to as a Node B, an evolved Node B (eNB), an access point, a base transceiver station (BTS), a radio base station, a radio transceiver, a basic service set (BSS), an extended service set (ESS), a home B node, a home evolved B node, a transmitting receiving point (TRP), or any other appropriate term in the field. As long as the same technical effect can be achieved, the base station is not limited to a specific technical term. In the embodiments of the present application, only a base station in an NR system is introduced as an example, but it should be noted that the specific type of base station is not limited.

[0019] A UE operating in an idle / inactive state must perform automatic gain control (AGC), time-frequency synchronization, etc. before receiving paging to ensure accurate reception of the paging physical downlink control channel (PDCCH) / physical downlink shared channel (PDSCH). In NR, AGC and time-frequency synchronization are completed using synchronization signal blocks (SSBs) in the idle / inactive state. However, the transmission period of SSBs is generally long (e.g., 20 ms), so the UE must wake up earlier before receiving paging. In addition, the UE may need to receive multiple SSBs to perform synchronization and AGC, resulting in high power consumption during SSB reception.

[0020] In related technologies, Channel State Information (CSI)-Reference Signal (RS) can be used for connected state synchronization, CSI measurement, Radio Resource Management (RRM) measurement, radio link monitoring, beam failure detection, beam management, AGC, etc. However, a UE in an idle (idle / inactive) state cannot complete these functions using CSI-RS. Therefore, in order to reduce power consumption, a Tracking Reference Signal (TRS) / CSI-RS is introduced in the Radio Resource Control (RRC) idle / inactive state to perform measurement assistance, thereby reducing power consumption overhead and achieving energy savings.

[0021] Because one TRS consists of four CSI-RS resources and the bandwidth allocated to the TRS is larger, TRS allows for better time-frequency tracking than SSBs. When idle / inactive TRS is available, the UE may skip multiple SSBs when synchronizing using the TRS before receiving a paging message in low signal-to-noise ratio conditions. When idle / inactive TRS is unavailable, assuming that the UE requires three SSBs to perform AGC, synchronization, RRM measurements, etc. before the paging occasion (PO), the UE must wake up more than 40 ms in advance. When idle / inactive TRS is available, assuming that the UE requires only one TRS and one SSB to complete AGC and synchronization before receiving a paging message, and because TRS are typically more densely arranged than SSBs, the UE must wake up less than 40 ms in advance, resulting in energy saving gains.

[0022] In the related art, a system information block (SIB) is introduced to carry the configuration of idle / inactive TRS / CSI-RS occasion(s), where the configuration information of the TRS / CSI-RS occasion(s) includes one or more TRS resource sets, and each TRS resource set includes a set of TRS resources.

[0023] Regarding the availability of idle / inactive UEs, the UE is currently permitted to support paging PDCCH-based availability indication and PEI-based availability indication. For the paging PDCCH-based L1 availability indication, upon receiving the availability indication, availability is valid for a predetermined period from the reference point. This period is called the validity duration. The length of the validity duration can be selected by higher layers. The reference point where the validity duration starts is the system frame number (SFN) of the first paging frame (PF) in the default discontinuous reception cycle (DRX cycle) in which the UE receives the availability indication. The length of the validity duration is expressed in time units of the default paging cycle, and the available values ​​are {1, 2, 4, 8, 16, 32,

[64] ,

[0128] ,

[0256] ,

[0512] }. When the length of the validity duration is not configured by higher layers, the UE assumes that the length of the validity duration is two default paging cycles.

[0024] The modification period is for updating SI messages other than SI messages related to the Earthquake and Tsunami Warning System (ETWS), Commercial Mobile Alert System (CMAS), and positioning assistance data, and is applied to UEs that configure a DRX cycle. If an SI message is changed in one modification period, the network side will include SI change indication information in the paging for the current modification period and broadcast the updated system information in the next modification period.

[0025] The boundary calculation method is as follows: SFN mod m=0, where m is the number of radio frames that make up the modification period, and is arranged according to the system information.

[0026] After a UE receives an idle / inactive TRS / CSI-RS availability indication, the UE considers the idle / inactive TRS / CSI-RS to be always valid within the validity duration from the reference point. However, within the validity duration, the configuration information carrying the idle / inactive TRS / CSI-RS occasion(s) or the configuration information carrying the length of the validity duration may change. When such a situation occurs, it is not yet clear how the UE handles the availability of the idle / inactive TRS / CSI-RS.

[0027] The embodiments of the present application provide a method, an apparatus, and a terminal for determining the effective duration of a reference signal, which are capable of determining the effective duration of a first reference signal and detecting the first reference signal during the effective duration.

[0028] Next, with reference to the drawings, a method for determining the effective duration of a reference signal provided in the embodiments of the present application according to some embodiments and use cases thereof will be described in detail.

[0029] In the present embodiment, as shown in FIG. Step 101, in which the terminal acquires first information in an idle state or in an inactive state; and step 102, in which the terminal determines a target valid duration of a first reference signal, including a tracking reference signal and / or a channel state information reference signal, according to the first information, or determines that the first reference signal is unavailable according to second availability indication information; the first information includes at least one of a system information message, a first availability indication, and a second availability indication; The present invention provides a method for determining the valid duration of a reference signal, wherein the first availability indication information is availability indication information of a first reference signal in a downlink control message, and the second availability indication information is availability indication information of the first reference signal received in a modification period in which system information modification indication information including configuration information of the first reference signal is received.

[0030] In an embodiment of the present application, in an idle state or an inactive state, the terminal determines the valid duration of the first reference signal in the idle state and / or the inactive state according to the first information, and can then detect the first reference signal within the valid duration of the first reference signal, so that 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 behavior of the terminal can be clarified.

[0031] In some embodiments, the step of determining a target effective duration of a first reference signal by the terminal using the first information includes: The method includes a step of determining, by the terminal, that an end time of the target valid duration is a first time, the first time being determined by a time when the first valid duration expires and a second time; The second time period is A time unit at which a boundary of a modification period is located, at which the time at which the terminal receives a system information (SI) message is located; a time unit in which an N-th modification period is located after the modification period in which the time at which the terminal receives the first system information message is located; A system frame number (SFN) in which a first paging frame (PF) is located in a time unit or a default discontinuous reception (DRX) cycle in which the terminal receives a first system information message; a time unit in which the terminal receives an updated system information block 1 indicating that the configuration information of the first reference signal has changed, or a system frame number in which a first paging frame in a default discontinuous reception period is located; a system frame number in which a first paging frame of an M-th discontinuous reception period after a default discontinuous reception period in which the time at which the terminal receives the first system information message is located; any one of P-th time units after the time unit in which the terminal receives the first system information message; The first system information message carries updated configuration information of the first reference signal, and the time unit includes a system frame number, a subframe, a slot, and a symbol, where M, N, and P are positive integers.

[0032] In the above embodiment, the first time is the earlier of the time when the first valid duration expires and the second time; or the first time is the time when the first valid duration expires; or The first time is the second time.

[0033] Here, the first SI message is an SI message of a system information block (SIB) including configuration information of a first reference signal in an idle state and / or an inactive state.

[0034] In some embodiments, the configuration information of the first reference signal is the length of the effective duration of the first reference signal; The first reference signal includes at least one item of opportunity configuration information.

[0035] Wherein, the configuration information of the first reference signal opportunity includes at least one resource set of at least one first reference signal, and the resource set includes: a tracking reference signal resource set identifier TRS-ResourceSetId, Frequency domain allocation information frequency domain allocation, Number of slots numofslot, Starting resource block startingRB, The number of resource blocks nrofRBs, Periodicity and Offset, first OFDM Symbol In Time Domain, Power Control Offset SS, Pseudo-collocation information, e.g., SSB-index, an availability indication identifier indBitID of the first reference signal corresponding to the resource set of the first reference signal; The parameter includes at least one of the following: scrambling identifier scrambling ID.

[0036] In some embodiments, the step of determining the valid duration of the first reference signal by the terminal according to second availability indication information includes: The method includes the terminal determining that the first reference signal is unavailable.

[0037] For example, in certain cases, the UE ignores the availability indication information of the received idle and / or inactive first reference signal, specifically, the UE receives the availability indication information of the idle and / or inactive first reference signal in certain cases, but still considers the idle and / or inactive first reference signal to be unavailable.

[0038] In some embodiments, the step of the terminal determining a target valid duration of a first reference signal according to the first information or determining that the first reference signal is unavailable according to second availability indication information includes: The method further includes a step of determining a target effective duration of the first reference signal based on the received first indication information, or a step of determining that the first reference signal is unavailable based on the received second availability indication information.

[0039] Here, the first indication information instructs the terminal in what manner to determine the valid duration of the first reference signal. For example, when the first indication information is true, the terminal determines that the first reference signal is unavailable based on the received first indication information, and when the first indication information is false, the terminal determines that the start time of the valid duration is a first start time and the end time is a first time based on the received first indication information.

[0040] Of course, when the first indication information is false, the received first indication information may determine that the first reference signal is unavailable, and when the first indication information is true, the received first indication information may determine that the start time of the valid duration is the first start time and the end time is the first time.

[0041] In some embodiments, the system information message includes configuration information of a first reference signal, and the step of determining a target effective duration of the first reference signal by the terminal according to the first information includes: The terminal may determine a valid duration of the first reference signal according to a change in configuration information of the first reference signal.

[0042] The change status of the arrangement information of the first reference signal is The length of the effective duration of the first reference signal is changed from the length of the first effective duration to the length of the second effective duration; The allocation information of the first reference signal opportunity has been changed; and and a parameter in at least one first reference signal resource set during the first reference signal opportunity is changed.

[0043] In some embodiments, the step of determining the valid duration of the first reference signal by the terminal according to a change status of configuration information of the first reference signal includes: When a parameter in at least one first reference signal resource set during the first reference signal opportunity changes and configuration information of the first reference signal applied to the terminal does not change, determining that a start time of the valid duration of the first reference signal is a first start time and an end time of the valid duration is a third time; When a parameter in at least one first reference signal resource set during the first reference signal opportunity changes and configuration information of the first reference signal applied to the terminal changes, determining that a start time of the valid duration of the first reference signal is a first start time and an end time is a third time; restarting the effective duration of the first reference signal or applying the second effective duration when the effective duration of the first reference signal is changed to the second effective duration; the first start time is a time when the terminal receives first availability indication information; The third time period is the first party at the time when the first validity duration expires; a second system frame number in which a first paging frame in a default discontinuous reception period is located, the first paging frame being the system frame number in which the next time the terminal receives availability indication information for the first reference signal is located; It is either one of the first and second terms, whichever is closer to the former.

[0044] In the above embodiment, restarting the effective duration of the first reference signal includes: The start time of the valid duration is a second time, and the end time is the time when the second valid duration expires.

[0045] In the above embodiment, applying the length of the second effective duration may include: the effective duration has a start time of a second time and an end time of a fifth time; The fifth time period is a first party, which is the system frame number of the first paging frame in the default discontinuous reception period in which the time of receiving the next first reference signal availability indication information is located; a second, which is the system frame number in which the first remaining valid duration expires and / or the system frame number in which the first paging frame in the default discontinuous receiving period is located; This includes any one of the first and second terms.

[0046] The length of the first remaining valid duration is the length of the remaining valid duration obtained by subtracting the length of the third valid duration from the length of the second valid duration, and the length of the third valid duration is the length of time between the second time and the first start time.

[0047] In some embodiments, if the end time is the system frame number in which the first remaining valid duration expires and / or the system frame number in which the first paging frame in the default discontinuous reception period is located, If the length of the remaining valid duration is less than 0, determining that the first reference signal will be invalid from the second time; If the length 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.

[0048] In some embodiments, the step of determining a target valid duration of a first reference signal by the terminal according to the second availability indication information comprises: If the second availability indication indicates that all tracking reference signals and / or channel state information reference signals deployed in the network are invalid, determining that an end time of the target valid duration is one of the following: a time unit in which the time at which the terminal receives the second availability indication information is located or in which a boundary of a related modification period is located; a time unit in which the time at which the terminal receives the second availability indication information is located or in which an A-th modification period after the associated modification period is located; a time unit in which the terminal receives the second availability indication information or a system frame number in which the first paging frame in the default discontinuous reception period is located; a system frame number in which a first paging frame of a B-th discontinuous reception period after a default discontinuous reception period in which a time at which the terminal receives the second availability indication is located is located; The time unit includes a system frame number, a subframe, a slot, and a symbol, A and B are positive integers, and all of the tracking reference signals and / or channel state information reference signals include the first reference signal.

[0049] In some embodiments, the step of determining a target effective duration of a first reference signal by the terminal using the first availability indication information includes: The method includes a step of determining, when the first availability indication information indicates that one or more resources or resource sets of the first reference signals are valid, that the start time of the target valid duration is a sixth time and that the end time is the time when the first valid duration expires or the length of a second remaining valid duration, wherein the length of the second remaining valid duration is the length of the first valid duration minus T, where T is the length of time between the sixth time and the time when the terminal received the first availability indication information, and the sixth time is the time when the terminal received the second availability indication information.

[0050] In a specific embodiment, the valid duration of the first reference signal in the idle state and / or inactive state ends at a system frame number where a boundary of a modification period is located. As shown in Figure 3, this embodiment includes the following steps. Step 1: At time T1, the UE receives a paging PDCCH containing a system information change (SI change) indication. Step 2: At time T2, the UE receives a paging PDCCH containing an availability indication of the first reference signal in an idle state and / or an inactive state. Step 3: The UE determines the validity duration according to the availability indication information of the first reference signal in the idle and / or inactive state, where the start time is the SFN where the first PF in the default DRX cycle is located at time T2, and the time length is the length of the validity duration configured in the current system information. Step 4: The UE detects the first reference signal in the idle state and / or the inactive state according to the configuration information of the first reference signal in the idle state and / or the inactive state during the valid duration. Step 5: At time T3, the UE receives an updated SIB-X carrying updated configuration information of the first reference signal in the idle state and / or the inactive state. Step 6: The UE considers that the first reference signal in the idle state and / or inactive state is unavailable from the SFN where the boundary of the modification period, which corresponds to time T3, is located. Step 7: The UE receives the indication of availability of the tracking reference signal in the idle state and / or inactive state at time T4, and determines the validity duration of the first reference signal in the idle state and / or inactive state. The UE considers the start time to be the SFN of the first PF in the default DRX cycle at time T4, and the duration to be the validity duration configured in the current system information at time T4. Step 8: During the validity duration, the UE detects the first reference signal in the idle state and / or the inactive state according to the updated configuration information of the first reference signal in the idle state and / or the inactive state received at time T3.

[0051] In another specific embodiment, the terminal ignores the availability indication information of the first reference signal in an idle state and / or an inactive state, and this embodiment includes the following steps: Step 1: At time T1, the UE receives a paging PDCCH containing system information change indication information. Step 2: At time T2, the UE receives a paging PDCCH containing an availability indication of the first reference signal in an idle state and / or an inactive state. Step 3: The UE ignores the received availability indication information of the first reference signal in the idle and / or inactive state, i.e., the UE still considers the first reference signal in the idle and / or inactive state to be invalid.

[0052] In yet another specific embodiment, the UE determines the availability of the first reference signal in the idle state and / or the inactive state according to the first indication information, and if the first indication information is set to true, it means that when the UE receives the availability indication information of the first reference signal in the idle state and / or the inactive state during the modification period in which the UE receives the system information change indication information, the UE ignores the availability indication information. If the first indication information is set to false, it means that the UE finds that the configuration information of the first reference signal in the idle state and / or the inactive state has changed during the validity duration, and the first reference signal in the idle state and / or the inactive state will become unavailable until the SFN at the boundary of the modification period in which the UE receives the new configuration information. This embodiment includes the following steps. Step 1: The UE receives first indication information set to true. Step 2: At time T1, the UE receives a paging PDCCH containing system information change indication information. Step 3: At time T2, the UE receives a paging PDCCH containing an availability indication of the first reference signal in an idle state and / or an inactive state. Step 4: The UE ignores the received availability indication information of the first reference signal in the idle and / or inactive state, i.e., the UE still considers the first reference signal in the idle and / or inactive state to be invalid.

[0053] In yet another specific embodiment, the configuration information of the first reference signal occasion(s) in the idle state and / or inactive state applied to the UE is not changed, and this embodiment includes the following steps: Step 1: At time T1, the UE receives a paging PDCCH containing system information change indication information. Step 2: At time T2, the UE receives a paging PDCCH containing an availability indication of the first reference signal in an idle state and / or an inactive state. Step 3: The UE determines the validity duration according to the availability indication information of the first reference signal in the idle and / or inactive state, where the start time is the SFN where the first PF in the default DRX cycle is located at time T2, and the time length is the length of the validity duration configured in the current system information. Step 4: The UE detects the first reference signal in the idle state and / or the inactive state according to the configuration information of the first reference signal in the idle state and / or the inactive state during the valid duration. Step 5: At time T3, the UE receives the updated SIB-X carrying the updated configuration information of the first reference signal in the idle state and / or the inactive state, and finds that the configuration information of the first reference signal in the idle state and / or the inactive state applied to the UE has not changed. Step 6: The UE always considers the first reference signal in the idle and / or inactive state to be valid before either of the following times C and D, whichever occurs first: C: Before the next idle and / or inactive first reference signal availability indication is received. D: Before the validity duration of the first reference signal in the idle and / or inactive state expires. Step 7: When the UE receives the availability indication information of 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 in the default DRX cycle of the indication information is located based on the availability indication information.

[0054] In another specific embodiment, the first reference signal occasion(s) configuration information in the idle state and / or inactive state applied to the UE is modified, and as shown in FIG. 4, this embodiment includes the following steps: Step 1: At time T1, the UE receives a paging PDCCH containing system information change indication information. Step 2: At time T2, the UE receives a paging PDCCH containing an availability indication of the first reference signal in an idle state and / or an inactive state.

[0055] In yet another specific embodiment, the validity period of the first reference signal applied to the UE in the idle state and / or inactive state is updated, and as shown in FIG. 5, this embodiment includes the following steps: Step 1: The UE receives availability indication information of a first reference signal in an idle state and / or an inactive state at T1.

Step 3: The UE receives the SI change indication information at time T2. Step 4: The UE receives the updated SI at time T3, which includes the updated valid duration length. Step 5: The UE determines the "length of the current valid duration" by taking the SFN at which the boundary of the modification period where time T3 is located as the starting point and using the length of the updated valid duration as the length of the remaining valid duration. Step 6: The UE considers the first reference signal in the idle and / or inactive state to be valid for the length of the current validity duration.
