[0048] In conjunction with the accompanying drawings, the following describes in detail the paging advance indication PEI detection, device, terminal and medium provided in the embodiments of the present application through some embodiments and their application scenarios.

[0049] The present application embodiment provides a paging advance indication PEI detection method, such as Figure 2 As shown, the PEI detection method provided in the embodiment of the present application includes the following steps 201:

[0050] Step 201: The network-side device broadcasts configuration parameters related to PEI-O.

[0051] In the PEI detection method provided in the embodiment of the present application, since the network side device can broadcast configuration parameters related to PEI-O, after the terminal obtains the configuration parameters, the terminal can determine the corresponding PEI-O information according to the configuration parameters.

[0052] Optionally, the above configuration parameters can be used to configure at least one of the following:

[0053] The time domain resources occupied by the paging advance indication monitoring opportunity PEI-MO set;

[0054] Frequency domain resources occupied by the PEI-MO set;

[0055] The PEI-MO set includes M paging advance indication opportunities PEI-O, where M is a positive integer;

[0056] The index of M PEI-O;

[0057] The PEI-MO set is associated with W paging occasions PO, where W is a positive integer;

[0058] The index of W POs;

[0059] A first list corresponding to the PEI-MO set, where the first list is used to configure relevant parameters of the M PEI-Os;

[0060] The relationship between M PEI-Os and W POs.

[0061] It is understandable that the PEI-MO set can also be a PEI-O set.

[0062] Further optionally, the time domain resources occupied by the PEI-MO set are L radio frames, where L is a positive integer. For example, one PEI-MO set is 1 radio frame.

[0063] Further optionally, the W POs are all or part of the POs included in at least one paging frame PF. For example, the W POs must be all the POs in one PF.

[0064] Optionally, a paging frame PF is a radio frame.

[0065] Optionally, the above-mentioned first list includes M first parameters, and the M first parameters correspond one-to-one to M PEI-Os; wherein each first parameter is used to indicate the time domain position of the first paging advance indication monitoring opportunity PEI-MO of the corresponding PEI-O.

[0066] It should be noted that each PEI-O includes one or more paging advance indication monitoring opportunities PEI-MO, and the first PEI-MO is the earliest PEI-MO in the time sequence among the multiple PEI-MOs. The paging advance indication monitoring opportunity PEI-MO belongs to the physical downlink control channel monitoring opportunity PDCCH MO.

[0067] Further optionally, the value of the first parameter is determined by a reference point, and the reference point includes at least one of the following:

[0068] The starting point of the PEI-MO collection;

[0069] The first PO among the at least one PO indicated by the PEI-O corresponding to the first parameter.

[0070] Specifically, when the value of the first parameter is determined by taking the first PO of at least one PO indicated by the corresponding PEI-O as a reference point, it specifically refers to taking the time domain position of the first physical downlink control channel monitoring opportunity PDCCH MO of the first PO as a reference point. The first PO is the earliest PO of the at least one PO in the time sequence.

[0071] Optionally, the number of PEI-O included in the above PEI-MO set is related to at least one of the following:

[0072] The number of POs associated with the PEI-MO set;

[0073] The number of first parameters contained in the first list corresponding to the PEI-MO set.

[0074] Further optionally, the association relationship between the M PEI-Os and the W POs satisfies:

[0075] Each PEI-O among the M PEI-Os is used to indicate at least one PO among the W POs.

[0076] Specifically, the index of at least one PO may include at least one of the following: an index of a PF where the at least one PO is located, an index of the at least one PO in the PF where the at least one PO is located.

[0077] It can be understood that, when at least one PO belongs to different PFs, the index of the at least one PO includes the index of the PF where each PO in the at least one PO is located; when at least one PO belongs to the same PF, the index of the at least one PO is the index of the at least one PO in the PF where the at least one PO is located.

[0078] Further optionally, the number of POs indicated by each PEI-O in the M PEI-Os is the same or different, and / or one PO can only be indicated by one PEI-O.

[0079] It can be understood that the total number of POs associated with the M PEI-Os is W, and W is equal to the number of paging occasion POs associated with the PEI-MO set.

[0080] Optionally, the indexes of the above-mentioned M PEI-Os and W POs may be respectively configured by the network side device for the M PEI-Os and W POs, or may be stipulated by the protocol, which is not limited in the embodiments of the present application.

[0081] Example 1: Figure 3As shown, the network side device configures a PEI-MO set (i.e., the above-mentioned PEI-MO set), and the time domain resource occupied by the PEI-MO set is a wireless frame. Among them, the PEI-MO set contains 2 PEI-Os. The network side device configures the PEI-MO set to associate all 4 POs in 1 PF, and the first 1 PEI-O indicates the first two POs (i.e., PO1 and PO2) of the 4 POs, and the second PEI-O indicates the last two POs (i.e., PO3 and PO4) of the 4 POs. The network side device also configures the PEI-MO set to correspond to a first list, and the first list contains the first parameters of each of the two PEI-Os, and the value of the first parameter is determined by taking the starting point of the PEI-MO set as a reference point.

[0082] In some embodiments, when the PEI-MO set includes K PEI-MOs, the paging advance indication PEI detection method provided in the present application may further include the following step 202 .

[0083] Step 202: The network side device groups K PEI-MOs to obtain M groups of PEI-MOs.

[0084] Wherein, a group of PEI-MO includes at least one PEI-MO, and K is a positive integer.

[0085] In some possible embodiments, the above step 202 may include the following step 202A or step 202B.

[0086] Step 202A: The network-side device groups K PEI-MOs according to the number of PEI-Os included in the PEI-MO set to obtain M groups of PEI-MOs.

[0087] Each group of PEI-MO corresponds to one PEI-O among the M PEI-Os.

[0088] Step 202B: The network-side device groups K PEI-MOs according to the number of first parameters included in the first list corresponding to the PEI-MO set to obtain M groups of PEI-MOs.

[0089] The PEI-MOs between the time domain positions of the first physical downlink control channel monitoring opportunity PDCCH MO of the PEI-Os corresponding to the two adjacent first parameter indications constitute one group of PEI-MOs in the M groups of PEI-MOs.

[0090] Further optionally, the DCI content carried on the PEI-MO in each PEI-MO group is consistent.

[0091] Example 2: Figure 4As shown, the network side configures a PEI-MO set, and the PEI-MO set includes 4 PEI-Os. Among them, each PEI-O includes 8 PEI-MOs (that is, there are 32 PEI-MOs in the PEI-MO set, and the PEI-MO set is divided into 4 groups); the PEI-MO set is associated with / indicates 4 POs. The network side device configures the corresponding first parameters for each of the 4 PEI-Os included in the PEI-MO set, and each PEI-O indicates a PO. Among them, the values ​​of the 4 first parameters are different. In this way, the value of the first parameter is determined by taking the first PO of at least one PO associated with its corresponding PEI-O as a reference point, that is, the time domain position of the first physical downlink control channel monitoring opportunity PDCCH MO of the first PO as a reference point.

[0092] Optionally, each of the M PEI-Os may include at least one PEI-MO. If there is overlap between the PEI-MOs corresponding to at least two PEI-Os in the M PEI-Os, the first downlink control information DCI transmitted on the overlapping PEI-MO includes: PEI information corresponding to the PO indicated by the first PEI-O. The first PEI-O is the at least two PEI-Os, and the first DCI is used to carry the PEI.

[0093] It can be understood that the first DCI refers to the DCI used to carry the PEI. In addition, the first DCI can also be used to carry other indications, such as TRS transmission information, etc., which is not limited here.

[0094] Further optionally, there is overlap between the PEI-MOs respectively corresponding to at least two PEI-Os among the M PEI-Os, including: there is partial overlap between the PEI-MOs corresponding to the at least two PEI-Os, and there is complete overlap between the PEI-MOs corresponding to the at least two PEI-Os.

[0095] Further optionally, there is overlap between the PEI-MOs respectively corresponding to at least two PEI-Os among the M PEI-Os, including: overlap between the PEI-MOs in the time domain and / or overlap between the PEI-MOs in the frequency domain.

[0096] Specifically, there is overlap between the PEI-MOs corresponding to the M PEI-Os, which may include the following possible situations:

[0097] (1) Since the first parameter values ​​corresponding to at least two PEI-Os among the M PEI-Os are the same, the PEI-MOs corresponding to the at least two PEI-Os overlap.

[0098] (2) Even if the values ​​of the first parameters corresponding to the M PEI-Os are different, there may be some overlap in the PEI-MOs corresponding to at least two of the M PEI-Os.

[0099] Further optionally, the PEI information corresponding to the PO indicated by the first PEI-O is placed in the first DCI according to the first rule.

[0100] The first rule includes at least one of the following:

[0101] The index value of the first PEI-O;

[0102] The index value of the PO indicated by the first PEI-O;

[0103] The index value of the PF where the PO indicated by the first PEI-O is located.

[0104] The index value of the PO indicated by the first PEI-O may be the index value of the PO configured by the network side, or may be the index value of the PO allocated in the PF where the PO is located.

[0105] It should be noted that the index value of the first PEI-O can be understood as the size of the index value of the first PEI-O. When the first rule includes the index value of the first PEI-O, it can be understood that the first rule is to place the PEI information corresponding to the PO indicated by the first PEI-O in a manner from large to small or from small to large according to the first PEI-O index value.

[0106] It should be noted that, when the PO indicated by the first PEI-O belongs to the same PF, the first rule is the index value of the PO indicated by the first PEI-O; when the PO indicated by the first PEI-O belongs to different PFs, the first rule is the index value of the PO indicated by the first PEI-O and the index value of the PF where the PO indicated by the first PEI-O is located.

[0107] For example, Figure 5 As shown, for the 4 POs belonging to PF1, the first rule is: according to the size of the index value of the PO, from small to large or from large to small; for the 4 POs belonging to PF1 and the 4 POs belonging to PF2, the first rule is: according to the size of the index values ​​of these 8 POs and the size of the index values ​​of the PFs where these 8 POs are located, from small to large or from large to small.

[0108] It should be noted that the PEI information corresponding to the PO indicated by the first PEI-O (here referred to as the target PO) is merged into the same DCI, that is, the PEI information corresponding to the target PO is carried by one DCI (i.e., the first DCI) by default. Among them, each target PO corresponds to a PEI information indication block in the DCI. For example, the length of each indication block is a maximum of 8 bits.

[0109] For example, Figure 5 As shown, it is assumed that the target PO is the first PO in PF1, that is, the index value of PO i_S=0, and the PEI information indication block corresponding to the first PO in DCI is indication block 1.

[0110] (1) When the target PO is a PO associated with the same PF, the PEI information corresponding to each target PO is placed in the DCI according to the order of the i_S index value corresponding to each target PO in the PF.

[0111] (2) When the target PO is associated with different PFs, the target POs associated with the same PF place the PEI information corresponding to each target PO in the DCI in the order of the i_S index value corresponding to each target PO in the PF; between the target POs associated with different PFs, the PEI information corresponding to the target POs of different PFs are placed in the indication block in the DCI in the order of the index value of the PF.

[0112] Example 3: Figure 5 As shown in FIG. 1 , the PEI-MO set configured by the network side device is associated with 8 POs, and the 8 POs belong to 2 PFs. In the case where there is overlap between the PEI-MOs corresponding to the PEI-Os included in the PEI-MO set, multiple PEI-Os corresponding to the overlapping PEI-MOs indicate the 8 POs. At this time, the PEI information of the 8 POs is carried in Figure 5 As shown in the DCI. Since these 8 POs belong to PF1 and PF2, the PEI information of these 8 POs can be placed on the DCI according to the index values ​​of the PFs where these 8 POs are located and the index values ​​of these 8 POs. In this way, the PEI information of the 4 POs belonging to PF1 is placed in indication blocks 1 to 4 of the DCI according to the index values ​​of these 4 POs; the PEI information of the 4 POs belonging to PF2 is placed in indication blocks 5 to 8 of the DCI according to the index values ​​of these 4 POs.

[0113] In the PEI detection method provided in an embodiment of the present application, the network side device configures the PEI-MO set and related parameters of the PEI-MO set through configuration parameters. If there is overlap between the PEI-MOs corresponding to at least two PEI-Os among the M PEI-Os contained in the PEI-MO set, the first DCI received on the overlapping PEI-MO is placed according to the first rule. The PEI information corresponding to the PO associated with the at least two PEI-Os is placed, thereby obtaining the configuration parameters at the terminal and detecting the PEI information of the corresponding PO.

[0114] The present application embodiment provides another method for detecting a paging advance indication PEI, such as Figure 6 As shown, the PEI detection method provided by the present application includes the following steps 301 and 302:

[0115] Step 301: The terminal obtains configuration parameters.

[0116] Among them, the configuration parameters are related to PEI-O.

[0117] Step 302: The terminal determines the PEI-O information associated with the PO corresponding to the terminal according to the configuration parameters.

[0118] In the PEI detection method provided in the embodiment of the present application, after the terminal obtains the configuration parameters, the terminal can determine the PEI-O information associated with the PO corresponding to the terminal according to the configuration parameters. Further, the terminal can detect the PEI according to the PEI-O information.

[0119] Currently, for User Equipment (UE) in idle state, UE needs to perform radio resource management (RRM) measurement and receive paging PDCCH channel. Since the probability of UE being paged in a paging occasion (PO) is not high, if UE performs paging PDCCH channel detection in each paging cycle, it will cause unnecessary power consumption.

[0120] In order to reduce the power consumption of UE, UE can receive paging advance indication information PEI before receiving paging PDCCH. In this way, UE can determine whether to monitor the subsequent paging PDCCH according to the content indicated in the paging advance indication PEI DCI. If PEI indicates that UE does not receive paging PDCCH, UE does not need to detect one or more (Synchronization Signal and PBCH block, SSB)) in the future, thus saving power consumption.

[0121] Based on the above problem, the terminal needs to determine PEI-O in order to detect the paging advance indication PEI associated with the terminal's corresponding PO.

[0122] Among them, one PEI-O can indicate multiple POs, and these multiple POs can be all POs contained in one PF, part of POs in one PF, or POs in multiple PFs.

[0123] For the above multiple POs, this case takes a set of PEI-MO sets (which can be understood as a PEI-frame) as a unit, designs it to associate multiple PEI-Os, and then designs the relevant parameter list for the PEI-MO set. This PEI configuration method based on PEI-MO sets can make PEI more centralized and simplify network configuration, saving signaling overhead.

[0124] In a possible embodiment, a list of related parameters for the first opportunity set may be configured through a first configuration parameter:

[0125] Optionally, the above configuration parameters can be used to configure at least one of the following:

[0126] The time domain resources occupied by the PEI-MO set;

[0127] Frequency domain resources occupied by the PEI-MO set;

[0128] The PEI-MO set includes M paging advance indication opportunities PEI-O, where M is a positive integer;

[0129] The index of M PEI-O;

[0130] The PEI-MO set is associated with W paging occasions PO, where W is a positive integer;

[0131] The index of W POs;

[0132] A first list corresponding to the PEI-MO set, where the first list is used to configure relevant parameters of the M PEI-Os;

[0133] The relationship between M PEI-Os and W POs.

[0134] Further optionally, the first list includes M first parameters, each of which is used to indicate the time domain position of the first PEI-MO of the corresponding PEI-O.

[0135] Further optionally, the value of the first parameter is determined by a reference point, and the reference point includes at least one of the following:

[0136] The starting point of the PEI-MO collection;

[0137] The first PO among the at least one PO indicated by the PEI-O corresponding to the first parameter.

[0138] Further optionally, the association relationship between the M PEI-Os and the W POs satisfies:

[0139] Each PEI-O in the M PEI-Os is used to indicate at least one PO in the W POs.

[0140] Further optionally, the number of POs indicated by each PEI-O in the M PEI-Os is the same or different, and / or one PO can only be indicated by one PEI-O.

[0141] Further optionally, the time domain resources occupied by the PEI-MO set are L radio frames, where L is a positive integer.

[0142] Further optionally, the W POs are all or part of the POs included in at least one paging frame PF.

[0143] Further optionally, each PEI-O of the M PEI-Os includes at least one PEI-MO;

[0144] If there is overlap between the PEI-MOs corresponding to at least two PEI-Os among the M PEI-Os, the first downlink control information DCI transmitted on the overlapping PEI-MO includes: the PEI information corresponding to the PO indicated by the first PEI-O; wherein the first PEI-O is the at least two PEI-Os, and the first DCI is used to carry the PEI.

[0145] It can be understood that the first DCI refers to the DCI used to carry the PEI. In addition, the first DCI can also be used to carry other indications, such as TRS transmission information, etc., which is not limited here.

[0146] Further optionally, the PEI information corresponding to the PO indicated by the first PEI-O is placed in the first DCI according to a first rule, and the first rule includes at least one of the following:

[0147] The index value of the first PEI-O;

[0148] The index value of the PO indicated by the first PEI-O;

[0149] The index value of the PF where the PO indicated by the first PEI-O is located.

[0150] Further optionally, the number of PEI-O included in the above PEI-MO set is related to at least one of the following:

[0151] The number of POs associated with the PEI-MO set;

[0152] The number of first parameters contained in the first list corresponding to the PEI-MO set.

[0153] Optionally, for a specific description of the configuration parameters, reference may be made to the description in the above embodiments, which will not be elaborated in the embodiments of the present application.

[0154] Optionally, the PEI-O information includes at least one of the following:

[0155] PEI-O;

[0156] PEI-O index;

[0157] The PEI-MO set corresponding to PEI-O;

[0158] The first parameter corresponding to PEI-O.

[0159] It should be noted that the above PEI-O refers to the PEI-O associated with the terminal, and associated means that the terminal needs to monitor PEI (also understood as PEI DCI) on the PEI-O.

[0160] Further optionally, the PEI-MO set corresponding to the above PEI-O may include at least one of the following:

[0161] The time domain resources occupied by the PEI-MO set;

[0162] Frequency domain resources occupied by the PEI-MO set;

[0163] The PEI-MO set includes M paging advance indication opportunities PEI-O, where M is a positive integer;

[0164] The index of the M PEI-Os;

[0165] The PEI-MO set is associated with W paging occasions PO, where W is a positive integer;

[0166] The index of W POs;

[0167] A first list corresponding to the PEI-MO set, the first list is used to configure relevant parameters of M PEI-Os;

[0168] The relationship between M PEI-Os and W POs.

[0169] It is understandable that after the terminal determines the PEI-O information according to the acquired configuration parameters, the terminal can know the PDCCH MO of the PEI-O associated with it according to the PEI-O information, so that the terminal can detect the target PEI information on the above PDCCH MO.

[0170] Optionally, after the above step 302, in an embodiment of the present application, the PEI detection method provided in the embodiment of the present application may further include the following step 303.

[0171] Step 303: The terminal detects target PEI information according to the PEI-O information and the second rule.

[0172] The target PEI information is the PEI information corresponding to the PO corresponding to the terminal.

[0173] The second rule includes at least one of the following:

[0174] The index value of the PO corresponding to the terminal;

[0175] The index value of the PF where the PO corresponding to the terminal is located.

[0176] Optionally, for the specific description of PEI-O information, reference may be made to the description in the above embodiment, which will not be repeated in the embodiments of the present application.

[0177] Optionally, in the embodiment of the present application, the target PEI information refers to the specific prompt content of the target PEI.

[0178] Optionally, the above target PEI information is carried in the target DCI, and the terminal detects the target DCI on the PEI-O associated with its corresponding PO.

[0179] Further optionally, the target DCI may be the first DCI, or other DCI, which is not limited in the embodiment of the present application.

[0180] It can be understood that, when the terminal can monitor the DCI in the time domain position information of the first PDCCH MO, if the DCI carries PEI information corresponding to multiple POs, the terminal can determine the specific target PEI information that needs to be detected in the DCI based on the index value of the corresponding PO or the index value of the PF where the PO is located, and detect the target PEI information in the DCI.

[0181] It should be noted that after the terminal detects the information of the target PEI, the terminal can determine whether to monitor subsequent POs according to the information of the target PEI.

[0182] Furthermore, when the target PEI information indicates that the paging PDCCH is not received, the terminal will not subsequently monitor the PO corresponding to the target PEI; when the target PEI information indicates that the paging PDCCH is received, the terminal will subsequently continue to monitor the PO corresponding to the target PEI information.

[0183] The following is an exemplary description of the PEI detection method provided in the examples of the present application.

[0184] Example 4: Figure 7 As shown, the network side device configures a PEI-MO set (i.e., the above-mentioned PEI-MO set), which is associated with / indicates 4 POs; the first list corresponding to the PEI-MO includes 4 first parameters, and each PEI-O indicates 2 POs.

[0185] In the case where the value of the first parameter is determined by using multiple POs as reference points, if the values ​​of the four first parameters are the same in pairs, then there will be overlap between the PEI-MOs corresponding to each PEI-O. In this way, the multiple POs indicated by each PEI-O in the multiple PEI-Os corresponding to the overlapping PEI-MO need to monitor the same DCI on the same group of PEI-MOs, that is, the first DCI transmitted on the overlapping PEI-MO contains: the PEI information corresponding to the POs indicated by the multiple PEI-Os. Figure 7 As shown, the first parameter values ​​corresponding to PO1 and PO2 are the same, so the PEI information corresponding to PO1 and PO2 is carried in the same DCI1, and DCI1 is monitored on the same set of PEI-MO; the PEI information corresponding to PO3 and PO4 is carried in the same DCI2, and DCI2 is monitored on the same set of PEI-MO.

[0186] In this way, if the terminal corresponds to PO1, the terminal can detect the PEI information (ie, target PEI information) corresponding to the indication block block1 in DCI1 according to the index value i_S=0 corresponding to PO1 in the PF.

[0187] It is understandable that after the terminal detects the target PEI information according to the PEI-O information and the second rule, the terminal can determine whether paging PDCCH detection is required according to the detected PEI information, without the UE having to perform paging PDCCH detection in each paging cycle, thereby reducing the power consumption of the terminal.

[0188] It should be noted that the PEI detection method provided in the embodiment of the present application can be performed by a PEI detection device, or a control module in the PEI detection device for performing the PEI detection method. In the embodiment of the present application, the method of performing PEI detection by a PEI detection device is taken as an example to illustrate the PEI detection device provided in the embodiment of the present application.

[0189] In addition, in the related technology, since the tracking reference signal CSI-RS / TRS (Tracking Reference Signal) in the current network belongs to the connected state configuration and can only support the connected state UE, if the CSI-RS / TRS serving the connected state UE is further configured to the idle state UE through system information, when the network does not need to continue to transmit a certain CSI-RS / TRS to the connected state UE, the terminal CSI-RS / TRS can be indicated through paging PDCCH or PEI whether it is transmitted, so that the network can flexibly control whether the CSI-RS / TRS is transmitted.

[0190] In order to reduce the transmission overhead of the indication information of whether the network indicates TRS transmission, one method is that the network configures the effective time of TRS transmission, that is, when the terminal receives the paging PDCCH indication to transmit TRS or the PEI indication to transmit TRS, the terminal cannot assume that TRS is still transmitted after the first time period, that is, no longer receive the TRS configured by the system information.

[0191] Optionally, the length of the first time period may be the length of N DRX cycles (paging cycles); or, the length of the first time period may be configured by system information.

[0192] The start time of the first time period may be the start time of the first PF of the current (receiving the paging PDCCH or PEI) DRX cycle, or the start time of the first PF of the next DRX cycle.

[0193] However, if Figure 8As shown, PEI indicating TRS is available for 4 DRX cycles. Validity Time according to PEI: 4 DRX cycles. Validity Time according to paging DCI: 4 DRX cycles. The first PF from current DRX cycle. Specifically, the DRX cycle starts with the first PF received by paging, and the transmission time of PEI is before PO, that is, it may be transmitted in the previous DRX cycle of the current DRX cycle, or it may be transmitted in the previous PF of the same DRX cycle. If the transmission time of PEI is transmitted in the previous DRX cycle of the current DRX cycle of PO, then if the starting time of the first time period of TRS transmission indicated by pagingPDCCH and PEI is the first PF or the next PF of the current DRX cycle or the next DRX cycle, it will cause the terminal to have inconsistent understanding of the valid time of TRS transmission.

[0194] In order to solve the above technical problems, in the prior art, the starting time of the first time period corresponding to the TRS transmission information indicated by the paging PDCCH and the starting time of the first time period corresponding to the TRS transmission information indicated by the PEI are defined differently. An embodiment of the present application also provides a method for determining the reference signal reception time, so that the starting time of the first time period corresponding to the TRS transmission information indicated by the paging PDCCH and the starting time of the first time period corresponding to the TRS transmission information indicated by the PEI are defined consistently.

[0195] The present application embodiment provides a method for determining a reference signal reception time, such as Fig. 9 As shown, the method includes the following steps 401 and 402:

[0196] Step 401: The terminal receives first TRS transmission information.

[0197] In one embodiment, the first TRS transmission information is used to activate a specific TRS transmission, that is, to indicate that the terminal can receive the specific TRS within a specific time period. The TRS transmission is used for a terminal in an RRC non-connected state. The specific TRS transmission may refer to a specific TRS configuration, which is not limited here.

[0198] Step 402: The terminal receives a TRS in a first time period according to the available TRS resources indicated by the first TRS transmission information.

[0199] The first TRS transmission information is carried in the second DCI, the second DCI includes a paging advance indication PEI, and the first time period is a time period corresponding to the first TRS transmission information.

[0200] Optionally, the start time of the first time period is one of the following:

[0201] a start time of a first PF of a first DRX cycle, where the first DRX cycle is the DRX cycle in which the PO associated with the second DCI is located;

[0202] a start time of a first PF of a second DRX cycle, where the second DRX cycle is a DRX cycle next to the first DRX cycle;

[0203] A start time of a first radio frame, where the first radio frame is a PF where the PO associated with the second DCI is located;

[0204] a start time of a first subframe, where the first subframe is a subframe with a specific subframe index, and the specific subframe index is configured by the network side;

[0205] The starting time of the second wireless frame, the second wireless frame has a specific frame index, and the specific frame index is configured by the network side.

[0206] Optionally, the starting time of the first time period is the starting time of the second time period, and the length of the first time period is the length of the second time period; wherein, the second time period is the time period corresponding to the second TRS transmission information, the second TRS transmission information is carried in the DCI of the PO associated with the second DCI, and the DCI of the PO associated with the second DCI is used for paging the terminal.

[0207] Optionally, the DCI of the PO associated with the above-mentioned second DCI includes third TRS transmission information.

[0208] It should be noted that the purpose of the third TRS transmission information is consistent with the purpose of the first and second TRS transmission information.

[0209] Optionally, the third TRS transmission information is the same as the first TRS transmission information.

[0210] It is understandable that the third TRS transmission information is the same as the first TRS transmission information in that the same refers to the same content. The same content may include: the specific TRS transmissions indicated to be activated by both are the same, and / or the time periods corresponding to the specific TRS transmissions indicated to be activated by both are the same.

[0211] Optionally, the second TRS transmission information is the same as the first TRS transmission information.

[0212] Optionally, the TRS transmission information indicated by the paging PDCCH is the same as the TRS transmission information indicated by the PEI.

[0213] Exemplarily, if TRS transmission information is indicated in the paging PDCCH, the starting time of the corresponding first time period is: the first PF of the current DRX cycle, or the first PF of the next DRX cycle; if TRS transmission information is indicated in the PEI, the starting time of the corresponding first time period is: the first PF of the DRX cycle where the PO associated with the PEI is located, or the first PF of the next DRX cycle. Furthermore, the above-mentioned PEI is used to indicate whether the UE corresponding to the PO associated with the PEI monitors the paging PDCCH on the PO (the paging PDCCH indicates TRS transmission information).

[0214] In the first time period, the network side device sends PEI or paging PDCCH, PEI or paging PDCCH is used to indicate TRS resources to be sent, and the terminal can receive the corresponding TRS according to the TRS resources to be sent indicated by PEI or the TRS resources to be sent indicated by paging PDCCH.

[0215] It can be understood that the starting position of the TRS transmission information indicated by the PEI and the starting position of the TRS transmission information indicated by the paging PDCCH transmitted on the PO associated with the PEI are the same, that is, both are the starting time of the first PF of the DRX cycle where the PO carrying the above paging PDCCH is located or the first PF of the next DRX cycle.

[0216] If the PEI indicates TRS transmission information, the start time of the first time period is the start time of the PF where the pagingPDCCH occasion (PO) associated with the PEI is located. Preferably, on the PO associated with the PEI, the UE also receives the same TRS transmission information as the PEI.

[0217] It can be understood that the starting position of the TRS transmission information indicated by the PEI and the starting position of the TRS transmission information indicated by the paging PDCCH transmitted on the PO associated with the PEI are the same, that is, both are the starting time of the PF where the PO carrying the above paging PDCCH is located.

[0218] If the starting time of the first time period corresponding to the network configured TRS transmission information is the starting position of a certain subframe or radio frame, then the starting position of the TRS transmission information indicated by the PEI and the starting position of the TRS transmission information indicated by the pagingPDCCH transmitted on the PO associated with the PEI are the same, that is, they are both the starting positions of the same subframe or radio frame.

[0219] It should be noted that the association between PEI and paging PDCCH in this embodiment is not limited to the association described in other embodiments of the present invention, that is, PEI can indicate whether the paging PDCCH of one PO is monitored, and can also indicate whether the paging PDCCH of multiple POs is monitored, which is not limited in this embodiment.
