Description

Technical Field

[0001] The present application relates to the field of communication processing technology, and in particular to a method for confirming an idle state reference signal and related products. Background Art

[0002] When the UE is in idle mode (RRC IDLE), the UE needs to monitor the paging PDCCH (paging Physical Downlink Control Channel). Generally speaking, the UE needs to determine the paging PDCCH monitoring occasion through PF (Paging Frame), PO (Paging Occasion) and paging search space set configuration. In 5G NR, the UE relies on the synchronization signal block for AGC (automatic gain control) adjustment / time-frequency tracking (channel tracking) / measurement. Since the synchronization signal block burst does not exist in every subframe or every time slot, the synchronization signal block burst is sent in a certain time period, such as 5 milliseconds, 10 milliseconds, 20 milliseconds, etc. Therefore, generally speaking, the UE needs to wake up before at least the last two synchronization signal block bursts before PO (Paging Occasion), and use these two synchronization signal block bursts for AGC adjustment / time-frequency synchronization, or AGC adjustment / time-frequency synchronization / measurement. When the UE has been in sleep for a long time, for example, the interval between two POs that the UE needs to monitor is large due to the PO configuration, the UE may need to wake up before the last three synchronization signal blocks before the PO burst, and use these three synchronization signal blocks to perform AGC adjustment / time-frequency synchronization, or AGC adjustment / time-frequency synchronization / measurement. This will cause the UE to wake up too long in advance and consume more power.

[0003] In order to reduce the time for UE to wake up in advance, the base station can configure additional reference signals and notify the UE. The UE can use only one synchronization signal block, plus the reference signal near the synchronization signal block, to perform AGC adjustment / time-frequency synchronization, or AGC adjustment / time-frequency synchronization / measurement, thus shortening the wake-up time and achieving energy saving. The reference signal can be a Tracking Reference Signal (TRS), a Channel State Information-Reference Signal (CSI-RS), or a Synchronization Signal (SS).

[0004] Existing UEs cannot confirm whether a reference signal is valid. Summary of the invention

[0022] The embodiments of the present application are described below in conjunction with the drawings in the embodiments of the present application.

[0023] The term "and / or" in this application is only a description of the association relationship of associated objects, indicating that there can be three relationships. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " in this article indicates that the associated objects before and after are in an "or" relationship.

[0024] The "multiple" that appears in the embodiments of the present application refers to two or more. The first, second, etc. descriptions that appear in the embodiments of the present application are only used for illustration and distinction of the description objects. There is no order, nor does it represent a special limitation on the number of devices in the embodiments of the present application, and cannot constitute any limitation on the embodiments of the present application. The "connection" that appears in the embodiments of the present application refers to various connection methods such as direct connection or indirect connection to achieve communication between devices, and the embodiments of the present application do not make any limitations on this.

[0025] The technical solution of the embodiment of the present application can be applied to Figure 1 The exemplary communication system 100 shown includes a terminal 110 and a network device 120 , wherein the terminal 110 is in communication connection with the network device 120 .

[0026] The terminal in the embodiments of the present application may refer to various forms of UE, access terminal, user unit, user station, mobile station, MS (English: mobile station, Chinese: mobile station), remote station, remote terminal, mobile device, user terminal, terminal equipment (English: terminal equipment), wireless communication equipment, user agent or user device. The terminal equipment may also be a cellular phone, a cordless phone, a SIP (English: session initiation protocol, Chinese: session initiation protocol) phone, a WLL (English: wireless local loop, Chinese: wireless local loop) station, a PDA (English: personal digital assistant, Chinese: personal digital processing), a handheld device with wireless communication function, a computing device or other processing device connected to a wireless modem, a vehicle-mounted device, a wearable device, a terminal device in a future 5G network or a terminal device in a future evolved PLMN (English: public land mobile network, Chinese: public land mobile communication network), etc., and the embodiments of the present application are not limited to this.

[0027] See also Figure 2 , Figure 2 A method for confirming an idle state reference signal is provided. The method is applied to a UE (User Equipment), and the method comprises the following steps:

[0028] Step S201: The UE confirms that the reference signal before the paging occasion PO is valid.

[0029] The UE derivation of the pre-PO reference signal of the technical solution provided in the present application is effective, and further confirms the validity of the reference signal to achieve the joint optimization of UE energy saving and system overhead, thereby improving UE performance and network performance.

[0030] In an optional solution, the method specifically includes:

[0031] The UE determines that n reference signals after a synchronization signal burst SS burst or synchronization signal block SS block closest to the PO are valid; the n is 1, 2 or 3. When the reference signal is TRS, 1 TRS can be multiple CSI-RS resources (CSI-RS resource), such as 2 or 4 CSI-RS resources. When the reference signal is CSI-RS, 1 CSI-RS can be 1 CSI-RS resource. When the reference signal is a synchronization signal, 1 synchronization signal can be a synchronization signal in 1 synchronization signal block.

[0032] The synchronization signal and broadcast channel form a synchronization signal block, thereby introducing the function of scanning beam. Through the primary synchronization signal (PSS) and the secondary synchronization signal (SSS), the UE obtains the time and frequency synchronization of a cell and obtains the physical layer cell ID of the cell. This process is generally called cell search. PSS, SSS and physical broadcast channel (PBCH) form a synchronization signal block (SS / PBCH block, or SS block). Each synchronization signal block has a predetermined time domain position. This time domain position can also be called a candidate synchronization signal block. Multiple synchronization signal blocks form an SS-burst (synchronization signal burst). Lmax synchronization signal blocks form a synchronization signal burst. The time domain position of Lmax synchronization signal blocks is fixed within a 5ms window. The time domain position indexes of Lmax synchronization signal blocks are arranged continuously, from 0 to Lmax-1. Therefore, the transmission time of a synchronization signal block within this 5ms window is fixed, and the index is also fixed. Generally speaking, the base station uses a beam sweeping method when sending synchronization signal blocks, that is, the base station sends synchronization signal blocks at different time domain positions through different beams. Correspondingly, the UE can measure different beams and sense which beam has the strongest signal received.

[0033] The SS burst in the present invention may refer to a burst within a time interval (such as within a 5ms window). Candidate synchronization signal blocks can also refer to The time interval of candidate synchronization signal blocks (such as a 5 ms window). In the present invention, SS block may refer to a synchronization signal block, and may also refer to a synchronization signal block associated with a paging monitoring opportunity or a paging PDCCH or a PI monitoring opportunity or a PI PDCCH.

[0034] The Paging Indication (PI) comes before the Paging Occasion (PO). PI is used to indicate whether the UE needs to monitor the PO. PI is also called the Paging Early Indication (PEI) or the Wake-Up Signal (WUS).

[0035] The PI in the present invention may also refer to a PI monitoring occasion or a PI PDCCH. A paging monitoring occasion may be a group of paging monitoring occasions or paging PDCCHs, and each paging monitoring occasion or paging PDCCH may be associated with a synchronization signal block. When a paging monitoring occasion or a paging PDCCH is associated with a synchronization signal block, the paging monitoring occasion or the paging PDCCH is quasi co-located (QCLed) with the synchronization signal block. The terminal may determine the paging monitoring occasion or the paging PDCCH to be monitored through the association relationship. The PI may be a group of PI monitoring occasions or PI PDCCHs, and each PI monitoring occasion or PI PDCCH may be associated with a synchronization signal block. When a paging monitoring occasion or a paging PDCCH is associated with a synchronization signal block, the PI monitoring occasion or the PI PDCCH is quasi co-located (QCLed) with the synchronization signal block. The terminal can determine the PI monitoring opportunity or PIPDCCH to be monitored through the association relationship. In the following, no distinction is made between PI and PI monitoring opportunity, nor between PI and PI PDCCH.

[0036] The UE needs to process a total of 3 SS bursts or SS blocks before PO (for AGC, time-frequency synchronization, etc.). One case: The UE processes 1 SS burst before PI. If the UE receives PI and determines that it needs to monitor PO, then the UE needs to process 2 SS bursts or SS blocks. At this time, the number of valid reference signals can be 1 or 2 (n=1 or 2). Another case: The UE processes 1 SS burst before PI, but after receiving PI, the UE enters deep sleep, so it needs to process 3 SS bursts before PO. At this time, the number of valid reference signals can be 1, 2, or 3 (n=1, 2, or 3).

[0037] The UE needs to process a total of 2 SS bursts or SS blocks before PO (for AGC, time-frequency synchronization, etc.). One case: The UE processes 1 SS burst before PI. If the UE receives PI and determines that it needs to monitor PO, then the UE needs to process 1 SS burst or SS block. At this time, the number of valid reference signals can be 1 (n=1). Another case: The UE processes 1 SS burst before PI, but after receiving PI, the UE enters deep sleep, so it needs to process 2 SS bursts before PO. At this time, the number of valid reference signals can be 1 or 2 (n=1 or 2).

[0038] The UE needs to process a total of 1 SS burst or SS block before PO (for AGC, time-frequency synchronization, etc.). One case: The UE processes 1 SS burst before PI, but after receiving PI, the UE enters deep sleep, so it needs to process another SS burst before PO. At this time, the number of valid reference signals can be 1 (n=1).

[0039] In summary, the number n of valid reference signals can be 1, 2 or 3

[0040] In the above technical solution, the base station or network side can only send n reference signals after the n SS bursts or SS blocks closest to the PO (before the PO), instead of sending all reference signals after all SS bursts or SS blocks closest to the PO (before the PO), saving system resource overhead.

[0041] The UE determines that n reference signals after a synchronization signal burst SS burst or SS block closest to the PO are valid, specifically including:

[0042] After the UE confirms that the reference signal closest to the SS burst or SS block closest to the PO is valid;

[0043] Or after the UE confirms that the reference signal closest to the PO is valid after the SS burst or SS block closest to the PO;

[0044] Or after the UE confirms that the two reference signals closest to the SS burst or SS block closest to the PO are valid;

[0045] Or after the UE confirms that the 2 reference signals closest to the PO are valid after the UE confirms the SS burst or SS block closest to the PO;

[0046] Or after the UE confirms that the 3 reference signals closest to the SS burst or SS block closest to the PO are valid;

[0047] Or after the UE confirms that the SS burst or SS block closest to the PO is valid, the three reference signals closest to the PO are valid.

[0048] If n=1 in the above scheme, the reference signal after the SS burst or SS block closest to the PO is the reference signal closest to the SS burst or SS block after the SS burst or SS block closest to the PO. In this way, the UE can process the reference signal as soon as possible after processing the SS burst or SS block closest to the PO and enter light sleep, thereby reducing power consumption.

[0049] If n=1 in the above scheme, the reference signal after the SS burst or SS block closest to the PO is the reference signal after the SS burst or SS block closest to the PO. In this way, the UE can enter light sleep after processing the SS burst closest to the PO, and wake up before the PO to process the reference signal (complete fine time-frequency synchronization) and receive the PO, thereby reducing power consumption.

[0050] If n=2 or 3 in the above scheme, the 2 or 3 reference signals after the SS burst or SS block closest to the PO are the 2 or 3 reference signals closest to the SS burst or SS block after the SS burst or SS block closest to the PO. In this way, the UE can process the 2 or 3 reference signals as soon as possible after processing the SS burst or SS block closest to the PO, enter light sleep, and reduce power consumption.

[0051] If n=2 or 3 in the above scheme, the 2 or 3 reference signals after the SS burst or SS block closest to the PO are the 2 or 3 reference signals closest to the PO after the SS burst or SS block closest to the PO. In this way, the UE can enter light sleep after processing the SS burst or SS block closest to the PO, and wake up before the PO to process the 2 or 3 reference signals (complete fine time-frequency synchronization) and receive the PO, thereby reducing power consumption.

[0052] In order to provide sufficient time for time-frequency synchronization, in an optional solution, the method specifically includes:

[0053] The UE confirms that the reference signal that is greater than or equal to T milliseconds, T time slots or T symbols away from the PO after the SS burst or SS block closest to the PO is valid.

[0054] The above distance from the PO is greater than or equal to T milliseconds or time slots or symbols, so that the UE can have enough time to process the reference signal before receiving the PO (it takes some time to process the reference signal for fine time-frequency synchronization). Otherwise, the UE can only cache the paging PDCCH and / or PDSCH in the PO before processing the reference signal. The above T can be configured by high-level parameters. The above T can have two types of candidate values, and the two types of candidate values ​​are respectively for UEs with different capabilities. The UE reports its ability to process the candidate values.

[0055] In an optional solution, the method specifically includes:

[0056] The UE confirms that after the SS burst or SS block closest to the PO, n reference signals whose distance from the PO is greater than or equal to T milliseconds, T time slots or T symbols are valid; the n is 1, 2 or 3.

[0057] In an optional solution, the UE confirms that a reference signal closest to the SS burst or SS block after the SS burst or SS block closest to the PO, which is greater than or equal to T milliseconds or time slots or symbols from the PO, is valid;

[0058] Or after the UE confirms that the SS burst or SS block closest to the PO is valid, the reference signal closest to the PO and whose distance from the PO is greater than or equal to T milliseconds or time slots or symbols;

[0059] Or after the UE confirms that the two reference signals closest to the SS burst or SS block closest to the PO are valid and the distance from the PO is greater than or equal to T milliseconds or time slots or symbols;

[0060] Or after the UE confirms that the two reference signals closest to the PO and whose distance from the PO is greater than or equal to T milliseconds or time slots or symbols are valid, the UE confirms that the two reference signals closest to the PO are valid;

[0061] Or after the UE confirms that the 3 reference signals closest to the SS burst or SS block closest to the PO and whose distance from the PO is greater than or equal to T milliseconds or time slots or symbols are valid;

[0062] Or after the UE confirms the SS burst or SS block closest to the PO, the three reference signals closest to the PO that are greater than or equal to T milliseconds or time slots or symbols away from the PO are valid.

[0063] In order to simplify the complexity of the system, in an optional solution, the method specifically includes:

[0064] The UE confirms that the reference signal after the nearest SS burst or SS block to the PO and the distance from the PO is less than or equal to S milliseconds, S time slots or S symbols is valid. In this way, the UE can determine that the reference signal within a window before the PO is valid, simplifying the system complexity.

[0065] In an optional solution, the method specifically includes:

[0066] The UE confirms that the reference signal after the second to last SS burst or SS block closest to the PO is valid.

[0067] The above scheme only needs one additional reference signal as an aid. The base station or network side can only send one reference signal after the second to last SS burst or SS block closest to the PO, saving system resource overhead.

[0068] In an optional solution, the method specifically includes:

[0069] The UE confirms that the n reference signals after the second to last SS burst or SS block closest to the PO are valid, where n is 1, 2 or 3.

[0070] In the above optional scheme, the n reference signals after the second to last SS burst or SS block closest to the PO are the n reference signals closest to the two SS bursts or SS blocks after the second to last SS burst or SS block closest to the PO. In this way, the UE can process the n reference signals as soon as possible after processing the two SS bursts or SS blocks closest to the PO, thereby improving the processing efficiency of the reference signals.

[0071] The n reference signals mentioned above can be 1, 2 or 3 reference signals when the restrictions are relaxed. The second to last SS burst or SS block closest to the PO is used as a reference, which can make more reference signals valid, compared with the SS burst or SS block closest to the PO. When system resource overhead is not a major issue, the base station can relax the restrictions to make more reference signals valid.

[0072] In an optional solution, the method specifically includes:

[0073] The UE confirms that the n reference signals closest to the SS burst or SS block after the second to last SS burst or SS block closest to the PO are valid;

[0074] Or the UE confirms that after the second to last SS burst or SS block closest to the PO, the n reference signals closest to the PO are valid.

[0075] The above n can be 1, 2 or 3

[0076] In the above optional scheme, the reference signal after the second to last SS burst or SS block closest to the PO is the reference signal closest to the PO after the second to last SS burst or SS block closest to the PO, so that the UE can enter light sleep after processing the two SS bursts or SS blocks closest to the PO, and wake up before the PO to process the reference signal (complete fine time-frequency synchronization) and receive the PO. The above reference signal can also be 2 reference signals or 3 reference signals.

[0077] In the above optional scheme, the additional condition "the distance from the PO is greater than or equal to T milliseconds or time slots or symbols" can allow the UE to have enough time to process the reference signal before receiving the PO (it takes some time to process the reference signal for fine time and frequency synchronization). Otherwise, the UE can only cache the paging PDCCH and / or PDSCH in the PO before processing the reference signal.

[0078] In an optional solution, the method specifically includes:

[0079] The UE confirms that the reference signal after the second to last SS burst or SS block closest to the PO and whose distance from the PO is greater than or equal to T milliseconds, T time slots or T symbols is valid.

[0080] In an optional solution, the method specifically includes:

[0081] The UE confirms that the n reference signals closest to the SS burst or SS block after the second last SS burst or SS block closest to the PO and whose distance from the PO is greater than or equal to T milliseconds or time slots or symbols are valid;

[0082] Or after the UE confirms the second to last SS burst or SS block closest to the PO, the n reference signals closest to the PO whose distance from the PO is greater than or equal to T milliseconds, T time slots or T symbols are valid.

[0083] In order to simplify the process of UE processing reference signals, in an optional solution, the method specifically includes:

[0084] The UE confirms that the reference signal in one, two or three synchronization occasions closest to the PO is valid.

[0085] In order to simplify the process of UE processing reference signals, in an optional solution, the method specifically includes:

[0086] The UE confirms that the reference signals in the 1, 2 or 3 synchronization opportunities after the PI and closest to the PI are valid. At this time, the UE knows that it needs to wake up through the PI. The UE can know that the reference signals in the 1, 2 or 3 synchronization opportunities after the PI and closest to the PI are valid, and process these reference signals to obtain synchronization.

[0087] In an optional solution, the synchronization opportunity includes: an SS burst and a reference signal;

[0088] Or the synchronization opportunity includes: an SS burst and a reference signal that is greater than or equal to T milliseconds or T time slots or T symbols away from the PO;

[0089] Or the synchronization opportunity includes an SSburst and a reference signal that are greater than or equal to T milliseconds or T time slots or T symbols away from the PO.

[0090] Embodiment 1

[0091] Embodiment 1 of the present application provides a method for confirming an idle state reference signal, which is executed by a UE. The technical scenario of the embodiment of the present application is that a paging indication (PI) is issued before a paging occasion (PO), and the PI is used to indicate whether the UE needs to monitor the PO. PI is also called a paging early indication (PEI) or a wake-up signal (WUS). The embodiment of the present application assumes that the UE needs to process a total of 3 SS bursts (for AGC, time-frequency synchronization, etc.) before PO. The embodiment of the present application assumes that the UE needs to process 1 SSburst plus 1 reference signal before PO. The method is as follows: Figure 3 As shown, it may specifically include:

[0092] Step S301: The UE determines that a reference signal after an SS burst or SS block closest to the PO is valid.

[0093] Specifically, the above-mentioned valid reference signal may specifically include:

[0094] The reference signal that is closest to the SS burst or SS block after the SS burst or SS block closest to the PO is valid.

[0095] Or the reference signal closest to the PO is valid.

[0096] A reference signal (which can be a reference signal closest to the SS burst or the reference signal closest to the PO) after the SS burst or SS block closest to the PO and which is greater than or equal to T milliseconds, time slots or symbols away from the PO is valid. The above T can be configured by a high-level parameter. The above T can have two types of candidate values. The two types of candidate values ​​are respectively for UEs with different capabilities, and the UE reports its capability to process the candidate values.

[0097] The technical solution provided in this embodiment uses a reference signal after a SS burst or SS block closest to the PO as the reference signal closest to the SS burst or SS block after a SS burst or SS block closest to the PO. In this way, the UE can process the reference signal as soon as possible after processing the SS burst or SS block closest to the PO, thereby improving the processing efficiency of the reference signal.

[0098] Embodiment 2

[0099] Embodiment 2 of the present application provides a method for confirming an idle reference signal, which is executed by a UE. The technical scenario of the embodiment of the present application is that the paging indication is before the paging opportunity, and the PI is used to indicate whether the UE needs to monitor the PO. The PI is also called a paging advance indication or a wake-up signal. The embodiment of the present application assumes that the UE needs to process a total of 2 reference signals (such as TRS) before the PO. At this time, the embodiment of the present application has a reference signal to assist. The 2 reference signals can replace 2 SS bursts, so it is equivalent to processing 2 SS bursts. The method is as follows Figure 4 As shown, it may specifically include:

[0100] Step S401: The UE determines that two reference signals after an SS burst closest to the PO are valid.

[0101] Specifically,

[0102] The UE confirms that the two reference signals closest to the SS burst after the SS burst closest to the PO are valid;

[0103] Or the UE confirms that the two reference signals closest to the PO after the SS burst closest to the PO are valid;

[0104] The UE confirms that two reference signals (which may be the two reference signals closest to the SS burst or the two reference signals closest to the PO) after the SS burst closest to the PO and whose distance from the PO is greater than or equal to T milliseconds, time slots or symbols are valid.

[0105] In the technical solution of the second embodiment of the present application, the two reference signals are closer to the PO than the one SS burst. The UE processes the two reference signals instead of the one SS burst, which can delay the wake-up time and save UE power consumption.

[0106] Embodiment 3

[0107] Embodiment 3 of the present application provides a method for confirming an idle reference signal, which is executed by a UE. The technical scenario of the embodiment of the present application is that the paging indication is before the paging opportunity, and the PI is used to indicate whether the UE needs to monitor the PO. The PI is also called a paging advance indication or a wake-up signal. The embodiment of the present application assumes that the UE needs to process a total of 3 reference signals (such as TRS) before the PO. At this time, the embodiment of the present application has a reference signal to assist, and the 3 reference signals can replace the 3 SS bursts, so it is equivalent to processing 3 SS bursts. The difference from the second embodiment is that the UE determines that the 3 reference signals after the 1 SS burst closest to the PO are valid.

[0108] See also Figure 5 , Figure 5 A device for confirming an idle state reference signal is provided, the device being applied to a UE, and the device comprising:
