Description

Technical Field

[0001] This disclosure relates to the field of communication technology, and in particular to a transmission method, apparatus, device and storage medium. Background Technology

[0002] In New Radio (NR) technology, power-saving design of User Equipment (UE) becomes essential, primarily because NR technology supports greater bandwidth, higher throughput, and more complex services and their corresponding more complex processing technologies.

[0003] Currently, during UE paging, the Paging Early Indication (PEI) serves as an indicator of whether the PDCCH (Paging Control Center) needs to monitor and schedule paging messages. By detecting the PEI before detecting paging messages, the UE can proceed with paging message reception if the PEI indicates that subsequent paging messages are required; otherwise, the UE can enter a low-power or sleep state, thereby reducing power consumption. Therefore, accurately determining the resource location of the PEI is crucial for the UE. Summary of the Invention

[0130] like Figure 1 As shown, the method may include:

[0131] Step 101: Determine the resource location of PEI based on the target paging frame PF.

[0132] In this embodiment, the above-mentioned resource location refers to the time domain location corresponding to the PEI. When the PEI is a PEI based on the Physical downlink control channel (PDCCH), the time domain location corresponding to the PEI is the time domain location corresponding to the first PDCCH listening time of the PEI based on PDCCH.

[0133] The target PF mentioned above is determined based on the paging parameters.

[0134] The paging parameters mentioned above include at least one of the following:

[0135] Discontinuous reception DRX period T; or

[0136] The total number of PFs N in each DRX cycle; or

[0137] The total number of paging opportunities (POs) in each PF, Ns; ​​or

[0138] The wireless frame number SFN_PF corresponds to PF; or

[0139] The first parameter A represents the total number of PFs corresponding to PEI.

[0140] The target PF is one of the A PFs corresponding to PEI.

[0141] Where A is an integer greater than or equal to 1.

[0142] The wireless frame number, also known as the system frame number, ranges from 0 to 1023.

[0143] In some embodiments, A can be obtained in multiple ways. As one possible implementation, a system message can be received, where the system message may include A. That is, the system message broadcast by the base station includes A. As another possible implementation, A is related to Ns and N1, where N1 represents the total number of paging occasions (POs) corresponding to the PEI, and A can be determined based on N1 and Ns.

[0144] In one embodiment of this disclosure, the above A satisfies: A = (Ceil(N1 / Ns)), where Ceil represents rounding up.

[0145] In some embodiments, when A is an integer greater than 1, the interval between the A PFs corresponding to PEI is less than the first threshold.

[0146] The first threshold represents the critical value of the number of radio frames or paging frames between the A PFs corresponding to the PEI.

[0147] The first threshold is related to T and N.

[0148] The first threshold can be obtained in several ways. For example, the UE can also receive system messages from the base station, where the first threshold is included. Alternatively, the UE can obtain the first threshold according to a communication protocol standard; that is, the first threshold can be defined in the communication protocol standard used by the UE.

[0149] In some embodiments, the interval between the A PFs can refer to the interval between the A PFs, or it can refer to the interval between the first PF and the last PF corresponding to a PEI.

[0150] In one embodiment of this disclosure, a possible implementation of determining the target PF based on paging parameters is as follows: determining a first index based on paging parameters, wherein the first index is used to determine the target PF, and the first index is determined based on intermediate values ​​Y and A, wherein the intermediate value Y is related to SFN_PF, N, and T.

[0151] In some embodiments, the UE may determine the first index corresponding to each PF based on the intermediate values ​​Y and A, and may agree in the communication protocol standard to use the PF with the first index value as the target PF.

[0152] The first value can be any integer from 0 to A-1. In other words, the communication protocol standard can stipulate that the PF corresponding to any value of the first index from 0 to A-1 is the target PF.

[0153] In other embodiments, the UE can determine the first index corresponding to each PF based on the intermediate values ​​Y and A, and can also broadcast a system message to notify that the PF with the first index value being a first value is the target PF. The first value can be any integer from 0 to A-1. The UE broadcasts a system message to notify that the PF with the first index value being any value from 0 to A-1 is the target PF.

[0154] In some embodiments, the first value can be 0. That is, it can be agreed that the PF with a first index of 0 is the target PF, i.e., the first PF among A PFs can be the target PF.

[0155] In some embodiments, the first index, Y, and A satisfy: first index = Y mod A, where mod represents the remainder.

[0156] In one embodiment of this disclosure, the above Y satisfies: Y = floor(SFN_PF*N / T), where floor represents rounding down.

[0157] It is understood that in some embodiments, the first index PF_Index satisfies the following formula: PF_Index=(floor(SFN_PF*N / T))mod A.

[0158] In one embodiment of this disclosure, a possible implementation of determining the resource location of the PEI based on the target paging frame PF is as follows: A reference frame corresponding to the PEI is determined based on the target PF and a first offset value, wherein the first offset value represents the offset between the target PF and the reference frame, and the target PF, the first offset value, and the reference frame satisfy the following relationship: (SFN_PEI + PEI_offset)mod T = SFN_OPF, or SFN_PEI + PEI_offset = SFN_OPF, where SFN_PEI represents the radio frame number of the reference frame, PEI_offset represents the first offset value, SFN_OPF represents the radio frame number corresponding to the target PF, and mod represents the remainder; the resource location of the PEI is determined based on the reference frame.

[0159] It is understandable that the aforementioned first offset value can be a frame-level offset, a slot-level offset, or a symbol-level offset.

[0160] In this embodiment, the first offset is preferably a frame-level offset. For example, the system message configures the first offset to be one or two radio frames.

[0161] In one embodiment of this disclosure, an exemplary implementation of determining the resource location of a PEI based on a reference frame is as follows: A second index PEI_i_s corresponding to the PEI in the reference frame is determined, where PEI_i_s satisfies: PEI_i_s = (floor(UE_ID / N)mod Ns)modX, where N1 represents the total number of paging opportunities corresponding to the PEI; X represents the total number of PEIs corresponding to the reference frame; UE_ID represents the identifier of the UE; and mod represents the modulo operation. Based on the second index, a target value corresponding to the second index is determined from X second offset values, and the resource location of the PEI is determined based on the reference frame and the target value.

[0162] In one embodiment of this disclosure, X can be obtained in various ways. For example, receiving a system message sent by a base station, wherein the system message includes X. That is, the UE can obtain X from the system message configured for it by the base station. As another example, X may be related to Ns and N1, and X may be determined by the UE based on Ns and N1.

[0163] In one embodiment of this disclosure, the above X satisfies: X = Ceil(Ns / N1), where Ceil represents rounding up.

[0164] In one embodiment of this disclosure, the value of X can be 1, 2, or 4. That is, X = 1, 2, or 4.

[0165] The second offset can be a frame-level offset, a slot-level offset, or a symbol-level offset. In this embodiment, the second offset is preferably a symbol-level offset.

[0166] For example, assuming N = T, Ns = 4, N1 = 8, then A = (Ceil(N1 / Ns)) = 2. The process of the UE calculating PF_Index is shown in Table 1 below. At this time, when the SFN_PF corresponding to the PF where the PO being monitored by the UE is located is equal to 2M, where M is an integer greater than or equal to 0, the UE determines PF_Index = 0 according to the PF_Index calculation formula. The UE can determine the target PF as the PF where the PO being monitored is located and determine the reference frame based on this target PF. When the SFN_PF corresponding to the PF where the PO being monitored by the UE is located is equal to 2M+1, where M is an integer greater than or equal to 0, the UE determines PF_Index = 1 according to the PF_Index calculation formula. The UE can substitute SFN_PF = 2M into the PF_Index calculation formula to obtain PF_Index = 0, and determine the PF corresponding to SFN_PF = 2M as the target PF. That is, the UE determines the target PF as the PF preceding the PF where the PO being monitored is located and determines the reference frame based on this target PF. Figure 2 As shown in the figure, the PF corresponding to SFN_PF = 2M is the target PF, such as... Figure 2 As shown by label C in the diagram. It should be noted that... Figure 2 The example also illustrates the relationship between the reference frame, the first offset, the second offset, and the target PF.

[0167] Table 1

[0168]

[0169] For example, assuming N = T, Ns = 4, N1 = 4, 2, or 1, then A = (Ceil(N1 / Ns)) = 1. The process of the UE calculating PF_Index is shown in Table 2 below. At this time, regardless of whether the SFN_PF corresponding to the PF where the PO being monitored by the UE is equal to 2M or 2M+1, where M is an integer greater than or equal to 0, the PF_Index determined by the UE according to the PF_Index calculation formula is equal to 0. The UE can determine that the target PF is the PF where its monitored PO is located, and determine the reference frame based on this target PF. For example... Figure 3 As shown, the PFs corresponding to N1=4, SFN_PF=2M, and SFN_PF=2M+1 are all target PFs, as follows. Figure 3As shown by label D in the diagram. Figure 4 As shown, the PFs corresponding to N1=2, SFN_PF=2M, and SFN_PF=2M+1 are all target PFs, as follows. Figure 4 As shown by the label E in the diagram. Figure 5 As shown, the PFs corresponding to N1=1, SFN_PF=2M, and SFN_PF=2M+1 are all target PFs, as follows. Figure 5 As shown by the label F in the diagram. It should be noted that the second bias value can be... Figure 5 The first offset value is one of the following: second offset value 0, second offset value 1, second offset value 2, and third offset value 3. Specifically, the first offset value 0 represents the offset between the start position of the reference frame and the first PEI among the multiple PEIs in the reference frame; the second offset value 1 represents the offset between the start position of the reference frame and the second PEI among the multiple PEIs in the reference frame; the second offset value 2 represents the offset between the start position of the reference frame and the third PEI among the multiple PEIs in the reference frame; and the second offset value 3 represents the offset between the start position of the reference frame and the fourth PEI among the multiple PEIs in the reference frame.

[0170] Table 2

[0171]

[0172] In summary, the UE determines the PF containing the PO it is monitoring as the target PF, or the UE determines the first PF with PF_Index = 0 preceding the PF containing the PO it is monitoring as the target PF. Here, the first PF with PF_Index = 0 refers to the PF with PF_Index = 0 that has the smallest distance to the PF containing the PO that the UE is monitoring, and from a temporal perspective, this first PF_Index = 0 is located before the PF containing the PO that the UE is monitoring. After determining the target PF, the UE determines the reference frame based on the target PF.

[0173] It should be noted that the UE determines that the PO it is listening to and the PF it resides in satisfy the following relationship:

[0174] (SFN+PF_offset)mod T=(T div N)*(UE_ID mod N)

[0175] The UE_ID mentioned above represents the identifier of the UE. As an example, the UEID is 5G-S-TMSI mod 1024, where 5G-S-TMSI is a 48-bit bit string.

[0176] It should be noted that each paging frame contains Ns POs, and the index of each PO is i_s, which is determined according to the following formula:

[0177] i_s = floor(UE_ID / N) mod Ns

[0178] It should be noted that the exemplary process by which the UE determines the DRX period ultimately used to receive paging is as follows: the UE determines the DRX period ultimately used to receive paging based on the minimum value between the DRX configured by higher-layer signaling and / or core network signaling and the default DRX period.

[0179] Among them, higher-layer signaling may include, but is not limited to, Radio Resource Control (RRC) signaling.

[0180] The default DRX cycle mentioned above can be obtained from system information; that is, system information includes the default DRX cycle.

[0181] Additionally, it should be noted that for the UE, it listens to one PO (Paging Occasion) in each DRX cycle. A PO consists of a set of PDCCH monitoring occasions (MOs), which can contain multiple time slots (e.g., subframes or OFDM symbols). Paging DCIs are transmitted on PDCCH MOs. A paging frame is a radio frame that can contain one or more POs or the starting point of a PO. In an exemplary embodiment of this disclosure, after determining the reference frame corresponding to the PEI, the UE needs to determine the specific time-domain location of the PEI based on the starting point of the reference frame. The specific time-domain location of the PEI can be determined by a second offset value. The base station can configure the second offset through a second parameter in the system message. Specifically, the second parameter can include at least one second offset, that is, the second parameter includes at least one numerical value, each numerical value corresponding to a second offset value. The second parameter can be represented as firstPDCCH-MonitoringOccasionOfPEI-O. When the reference frame corresponds to one PEI, one value can be configured in `firstPDCCH-MonitoringOccasionOfPEI-O`; when the reference frame corresponds to two PEIs, two values ​​can be configured in `firstPDCCH-MonitoringOccasionOfPEI-O`; and when the reference frame corresponds to four PEIs, four values ​​can be configured in `firstPDCCH-MonitoringOccasionOfPEI-O`. When the reference frame corresponds to multiple PEIs, the UE needs to determine which value in `firstPDCCH-MonitoringOccasionOfPEI-O` corresponds to the PEI it is monitoring. In this case, the UE can determine the target value based on the second index. The target value is the value among X values ​​corresponding to the second offset value of the PEI being monitored by the UE.

[0182] It can be understood that the aforementioned second index determines the target index of the PEI within at least one PEI index included in the reference frame. This target index can be used to determine the specific resource location of the PEI within the reference frame. For example, if the reference frame includes two PEIs, then the base station configuration "firstPDCCH-MonitoringOccasionOfPEI-O" includes two values: the resource location of the PEI corresponding to PEI_i_s = 0 is determined according to the first value in "firstPDCCH-MonitoringOccasionOfPEI-O", and the resource location of the PEI corresponding to PEI_i_s = 1 is determined according to the second value in "firstPDCCH-MonitoringOccasionOfPEI-O".

[0183] The following describes in more detail the process of determining the resource location of the PEI based on the second index, given that the reference frame is determined:

[0184] The UE determines the PEI's PDCCH listening opportunity based on the first PDCCH listening opportunity "firstPDCCH-MonitoringOccasionOfPEI-O" configured in the "DownlinkConfigCommonSIB" field of the paging search space and downlink configuration common system information block (SIB), and the total number of paging PDCCH MOs corresponding to a synchronization signal block (SSB) "nrofPDCCHMonitoringOccasionPerSSB-InPO". When the paging search space is configured with "SearchSpaceId=0", the PEI's PDCCH listening opportunity is the same as the Remaining Minimum SI (RMSI).

[0185] When the "SearchSpaceId" configured in the paging search space configuration is not equal to 0, the UE listens to the (PEI_i_s+1)th PEI. A PEI is a set of "S*X1" consecutive PDCCH listening opportunities, where S is the number of SSBs actually transmitted based on the SSB location information carried by SIB1, and X1 represents the total number of paging PDCCH MOs corresponding to each SSB configured in "nrofPDCCHMonitoringOccasionPerSSB-InPO". If this value is not configured, X1 equals 1. When "firstPDCCH-MonitoringOccasionOfPEI-O" is configured, the first PDCCH listening opportunity of the (PEI_i_s+1)th PEI is the (PEI_i_s+1)th value of the second parameter "firstPDCCH-MonitoringOccasionOfPEI-O" configured by the higher layer; otherwise, the first PDCCH listening opportunity of the (PEI_i_s+1)th PEI is equal to PEI_i_s*S*X1.

[0186] Step 102: Receive PEI at the resource location, where PEI is used to indicate the presence of paging.

[0187] In one embodiment of this disclosure, the PEI can be used to indicate at least one of the following: whether paging DCI (Downlink Control Information) exists at the PO, or whether paging DCI is detected at the PO, or whether a paging message is detected, or whether it is necessary to wake up to detect a paging message during the current paging cycle; or paging messages exist at the PO, or paging DCI is detected at the PO, or a paging message is detected, or it is necessary to wake up to detect a paging message during the current paging cycle.

[0188] In some embodiments of this disclosure, the PEI described above may indicate the presence of a paging message at at least one paging time corresponding to the PEI.

[0189] Specifically, the UE can determine the paging time it needs to listen to, and determine the presence of paging messages at that paging time based on the PEI, and determine whether to enter a low-power or sleep state based on the presence of paging messages at that paging time.

[0190] The transmission method of this disclosure accurately determines the target PF from the PF corresponding to the PEI by combining paging parameters, and accurately determines the resource location of the PEI based on the target PF, receiving the PEI at the resource location. This allows the UE to determine whether to enter a low-power or sleep state based on the indication of the PEI, thereby avoiding the UE continuously listening to paging control information on the PO and reducing the UE's power consumption.

[0191] Figure 6 This is a flowchart illustrating another transmission method provided according to an embodiment of the present disclosure, which is executed by the UE.

[0192] like Figure 6 As shown, the method may include:

[0193] Step 601: Determine the resource location of PEI based on the PEI time window.

[0194] In this embodiment, the above-mentioned resource location refers to the time domain location corresponding to the PEI. When the PEI is a PEI based on the Physical downlink control channel (PDCCH), the time domain location corresponding to the PEI is the time domain location corresponding to the first PDCCH listening time of the PEI based on PDCCH.

[0195] In this embodiment, the resource location of PEI refers to the resource location of the PEI that the UE needs to monitor.

[0196] In some embodiments, one possible implementation of determining the resource location of PEI based on the time window of PEI is as follows: the starting resource location for UE to listen to PEI can be determined based on the starting location of the time window of PEI, and the resource location for UE to listen to PEI is located inside the time window of PEI.

[0197] Step 602: Receive PEI at the resource location, wherein the PEI is used to indicate the presence of paging.

[0198] In one embodiment of this disclosure, the PEI can be used to indicate at least one of the following: whether paging DCI (Downlink Control Information) exists at the PO, or whether paging DCI is detected at the PO, or whether a paging message is detected, or whether it is necessary to wake up to detect a paging message during the current paging cycle; or paging messages exist at the PO, or paging DCI is detected at the PO, or a paging message is detected, or it is necessary to wake up to detect a paging message during the current paging cycle.

[0199] In some embodiments of this disclosure, the PEI described above may indicate the presence of a paging message at at least one paging time corresponding to the PEI.

[0200] Specifically, the UE can determine the paging time it needs to listen to, and determine the presence of paging messages at that paging time based on the PEI, and determine whether to enter a low-power or sleep state based on the presence of paging messages at that paging time.

[0201] The paging advance indication transmission method of this disclosure combines the time window of the PEI to determine the resource location of the PEI and receives the PEI at that resource location. This allows the UE to determine whether to enter a low-power or sleep state based on the PEI indication, thereby avoiding continuous listening to paging control information on the PO and reducing UE power consumption.

[0202] Figure 7 This is a flowchart illustrating another transmission method provided according to an embodiment of the present disclosure, which is executed by the UE.

[0203] like Figure 7 As shown, the method may include:

[0204] Step 701: Determine the resource location of PEI based on the time window of the target paging frame PF and PEI.

[0205] In one embodiment of this disclosure, the time window of the PEI is determined by the start position (PTW_start_PEI) and end position (PTW_end_PEI) of the PEI time window.

[0206] In some embodiments, the time window of the PEI mentioned above may include at least one DRX cycle.

[0207] For each DRX cycle, the target PF in that DRX cycle can be determined, and the resource location of PEI can be determined based on the target PF.

[0208] The target PF is determined based on the paging parameters.

[0209] For details on the specific implementation of determining the target PF based on paging parameters, please refer to the relevant descriptions in the above embodiments, which will not be repeated here.

[0210] The paging parameters include at least one of the following:

[0211] Discontinuous reception DRX period T; or

[0212] The total number of PFs N in each DRX cycle; or

[0213] The total number of paging opportunities (POs) in each PF, Ns; ​​or

[0214] The wireless frame number SFN_PF corresponds to PF; or

[0215] The first parameter A represents the total number of PFs corresponding to PEI.

[0216] The target PF is one of the A PFs corresponding to PEI.

[0217] Where A is an integer greater than or equal to.

[0218] The wireless frame number, also known as the system frame number, ranges from 0 to 1023.

[0219] In some embodiments, A can be obtained in multiple ways. As one possible implementation, a system message can be received, wherein the system message may include A. That is, the system message broadcast by the base station includes A. As another possible implementation, A is related to Ns and N1, where N1 represents the total number of paging opportunities corresponding to the PEI, and A can be determined based on N1 and Ns.

[0220] In one embodiment of this disclosure, the above A satisfies: A = (Ceil(N1 / Ns)), where Ceil represents rounding up.

[0221] In some embodiments, when A is an integer greater than 1, the interval between the A PFs corresponding to PEI is less than the first threshold.

[0222] The first threshold represents the critical value of the number of radio frames or paging frames between the A PFs corresponding to the PEI.

[0223] The first threshold is related to T and N.

[0224] The first threshold can be obtained in several ways. For example, the UE can also receive system messages from the base station, where the first threshold is included. Alternatively, the UE can obtain the first threshold according to a communication protocol standard; that is, the first threshold can be defined in the communication protocol standard used by the UE.

[0225] In some embodiments, the interval between the A PFs can refer to the interval between the A PFs, or it can refer to the interval between the first PF and the last PF corresponding to a PEI.

[0226] For details on the specific implementation of determining the resource location of PEI based on the target PF, please refer to the description of the above embodiment, which will not be repeated here.

[0227] Based on the above description, it can be seen that in the technical solution of determining the resource location of the PEI by combining the time windows of the target paging frame PF and PEI, after determining the time window of the PEI, it can be achieved through... Figure 1 The method shown in the embodiment determines the resource location of PEI within a time window of PEI.

[0228] Step 702: Receive PEI at the resource location, wherein the PEI is used to indicate the presence of paging.

[0229] For the specific implementation of step 702, please refer to the relevant description in the above embodiments, which will not be repeated here.

[0230] The transmission method of this disclosure determines the resource location of the PEI based on the time window of the target paging frame PF and PEI, and receives the PEI at that resource location. This allows the UE to determine whether to enter a low-power or sleep state based on the indication of the PEI, thereby avoiding the UE continuously listening to paging control information on the PO and reducing the UE's power consumption.

[0231] For the PEI time window in any of the above embodiments, one possible implementation of determining the PEI time window is as follows: Figure 8 As shown, it may include:

[0232] Step 801: Determine the PEI time window based on the third bias value and the start and end positions of the paging time window PTW corresponding to the UE.

[0233] The third bias value represents the bias between the starting position of the PEI time window and the starting position of the PTW.

[0234] The paging time window (PTW) corresponding to the UE can be determined using existing technologies. An exemplary implementation for determining the PTW corresponding to the UE can be: determining the PTW corresponding to the UE based on the UE's identification information and the extended discontinuous reception eDRX period corresponding to the UE.

[0235] It should be noted that the PTW window is at the UE level, and the PTW window may differ between different UEs. The PTW window is determined based on the PH (Programmable Context), the start position (PTW_start) of the PTW within the PH, and the end position (PTW_end) of the PTW.

[0236] The superframe number (H-SFN) to which PH resides satisfies the following relationship:

[0237] H-SFN mod TeDRX_CN=(UE_ID_H mod TeDRX_CN)

[0238] Where TeDRX_CN is the length of the eDRX period, which is in units of superframes, and 1 superframe equals 1024 radio frames; UE_ID_H is an identifier ID corresponding to the UE, and mod indicates the remainder.

[0239] The radio frame number (SFN) at which the PTW window begins (PTW_start) is located satisfies the following formula:

[0240] SFN = 128 * ieDRX_CN, where

[0241] ieDRX_CN=floor(UE_ID_H / TeDRX_CN)mod 8

[0242] The radio frame number (SFN) at the end position (PTW_end) of the PTW window satisfies the following formula:

[0243] SFN = (PTW_start + L * 100 - 1) mod 1024, where L is the configured PTW window length.

[0244] In one embodiment of this disclosure, a possible implementation of determining the PEI time window based on the third offset value, the start position and the end position of the paging time window PTW corresponding to the UE is as follows: determine the start position PTW_start_PEI of the PEI time window based on the start position of PTW and the third offset value.

[0245] In one embodiment of this disclosure, the end position of the PEI time window is determined based on the end position of the PTW. As an example, the end position of the PTW can be used as the end position of the PEI time window.

[0246] In another embodiment of this disclosure, one possible implementation of determining the PEI time window based on the third offset value, the start position and the end position of the paging time window PTW corresponding to the UE is as follows: determine the end position PTW_end_PEI of the PEI time window based on the end position of PTW and the third offset value.

[0247] In one embodiment of this disclosure, the start position of the PEI time window can be determined based on the start position of the PTW.

[0248] In another embodiment of this disclosure, one possible implementation of determining the PEI time window based on the third offset value, the start position and the end position of the paging time window PTW corresponding to the UE is as follows: the start position of the PEI time window PTW_start_PEI is determined based on the start position of PTW and the third offset value; the end position of the PEI time window PTW_end_PEI is determined based on the end position of PTW and the third offset value.

[0249] In one embodiment of this disclosure, PTW_start_PEI satisfies: PTW_start_PEI = PTW_start – PEI_offset3, or (PTW_start_PEI + PEI_offset3) mod first preset value = PTW_start, where PTW_start represents the starting position of PTW, PEI_offset3 represents the third offset value, and mod represents the remainder.

[0250] In one embodiment of this disclosure, the first preset value can be 1024.

[0251] In one embodiment of this disclosure, PTW_end_PEI satisfies: PTW_end_PEI = PTW_end – PEI_offset3, or (PTW_end_PEI + PEI_offset3) mod the second preset value = PTW_end, where PTW_end represents the end position of PTW, PEI_offset3 represents the third offset value, and mod represents the remainder.

[0252] In one embodiment of this disclosure, the second preset value can be 1024.

[0253] In one embodiment of this disclosure, when the radio frame number corresponding to the starting position of the PTW is greater than or equal to the third offset value, PTW_start_PEI satisfies: PTW_start_PEI = PTW_start – PEI_offset3; PTW_end_PEI satisfies: PTW_end_PEI = PTW_end – PEI_offset3.

[0254] For example, when an eDRX cycle is configured, if the UE is in an idle state, it listens for paging opportunities (POs) within the PTW window of the eDRX cycle. Assume the UE determines that its corresponding Hyperframe-System Frame number (H-SFN) = 2 within the eDRX cycle, and that the UE listens for POs within the PTW window where H-SFN = 2; it does not listen for POs outside the PTW window. Furthermore, assuming one PEI corresponds to two POs within the PTW window, an example diagram illustrating the relationship between the UE's PTW and the time windows corresponding to the PEI is shown below. Figure 9 As shown, through Figure 9It can be seen that the starting position of the PEI time window, PTW_start_PEI, is before the starting position of PTW_start. Furthermore, there is a third offset value between the starting position of the PEI time window, PTW_start_PEI, and the starting position of PTW_start. PTW_end_PEI is before PTW_end, and there is a third offset value between PTW_end_PEI and PTW_end.

[0255] In another embodiment of this disclosure, when the radio frame number corresponding to the end position of PTW is less than the third offset value, PTW_start_PEI satisfies: (PTW_start_PEI + PEI_offset3) mod the first preset value = PTW_start; PTW_end_PEI satisfies: (PTW_end_PEI + PEI_offset3) mod the second preset value = PTW_end.

[0256] In one embodiment of this disclosure, in the technical solution of determining the resource location of PEI by combining the time windows of the target paging frame PF and PEI, the value of the third offset value in this technical solution is the same as the value of the first offset value, wherein the first offset value represents the offset value between the reference frame corresponding to the target PF and PEI.

[0257] In one embodiment of this disclosure, the superframe number corresponding to PEI is the same as the superframe number corresponding to PF, or the superframe number corresponding to PEI is equal to the superframe number corresponding to PF minus a third preset value.

[0258] In one embodiment of this disclosure, the third preset value is 1 or 1024. That is, PH_PEI and PH satisfy the following formula: PH_PEI = PH - 1, or PH_PEI = PH - 1024, where PH_PEI represents the superframe number corresponding to PEI, and PH represents the superframe number corresponding to PF.

[0259] In one embodiment of this disclosure, when the radio frame number corresponding to the starting position of the PTW is greater than or equal to the third offset value, H_PEI = PH, where PH_PEI represents the superframe number corresponding to PEI and PH represents the superframe number corresponding to PF.

[0260] In another embodiment of this disclosure, when the radio frame number corresponding to the starting position of the PTW is less than the third offset value, PH_PEI and PH satisfy the following formula: PH_PEI = PH-1, or PH_PEI = PH-1024, where PH_PEI represents the superframe number corresponding to PEI and PH represents the superframe number corresponding to PF.

[0261] For the PEI time window in any of the above embodiments, another possible implementation of determining the PEI time window is: determining the PEI time window based on at least one of the third bias value, the start position of PTW, and the end position of PTW.

[0262] The third bias value represents the bias between the starting position of the PEI time window and the starting position of the PTW.

[0263] In one embodiment of this disclosure, the third offset value is the same as the first offset value, wherein the first offset value represents the offset between the target PF and the reference frame corresponding to the PEI.

[0264] In one embodiment of this disclosure, the target PF, the first offset value, and the reference frame satisfy the following relationship: (SFN_PEI + PEI_offset)mod T = SFN_OPF, or SFN_PEI + PEI_offset = SFN_OPF, where SFN_PEI represents the radio frame number of the reference frame, PEI_offset represents the first offset value, SFN_OPF represents the radio frame number corresponding to the target PF, and mod represents the remainder.

[0265] It should be noted that for UEs in a disconnected state (disconnected state includes idle state or inactive state), if the UE's eDRX period exceeds 1024 radio frames, it can be adjusted according to... Figure 8 The method shown is used to determine the time window of PEI.

[0266] Figure 10This is a schematic flowchart of a transmission method provided according to an embodiment of the present disclosure. The transmission method is performed by a base station. The base station is an entity on the network side used for transmitting or receiving signals. The base station may include multiple cells providing services to terminals. Depending on the specific application, the base station may also be called an access point, or a device in the access network that communicates with a wireless terminal device via one or more sectors on the air interface, or other names. The network device can be used to exchange received air frames with Internet Protocol (IP) packets, acting as a router between the wireless terminal device and the rest of the access network, where the rest of the access network may include an Internet Protocol (IP) communication network. The network device can also coordinate the attribute management of the air interface. For example, the network equipment involved in the embodiments of this application can be a base transceiver station (BTS) in a Global System for Mobile communications (GSM) or Code Division Multiple Access (CDMA), a NodeB in a Wide-band Code Division Multiple Access (WCDMA) system, an evolved Node B (eNB or e-NodeB) in a long term evolution (LTE) system, a 5G base station (gNB) in a next generation system, a Home evolved Node B (HeNB), a relay node, a femto, a pico, etc., and is not limited in the embodiments of this application. In some network structures, the network equipment may include centralized unit (CU) nodes and distributed unit (DU) nodes, and the centralized unit and distributed unit may be geographically separated.

[0267] like Figure 10 As shown, the transmission method may include:

[0268] Step 1001: Determine the resource location of PEI based on the target paging frame PF.

[0269] In this embodiment, the aforementioned resource location refers to the time-domain location corresponding to the PEI monitored by the user equipment (UE) communicating with the base station. When the PEI is a PDCCH-based PEI, the time-domain location corresponding to the PEI is the time-domain location corresponding to the first PDCCH monitoring time of the PDCCH-based PEI.

[0270] The target PF is determined based on the paging parameters.

[0271] The paging parameters mentioned above may include at least one of the following:

[0272] Discontinuous reception DRX period T; or

[0273] The total number of PFs N in each DRX cycle; or

[0274] The total number of paging opportunities (POs) in each PF, Ns; ​​or

[0275] The wireless frame number SFN_PF corresponds to PF; or

[0276] The first parameter A represents the total number of PFs corresponding to PEI.

[0277] The target PF is one of the A PFs corresponding to PEI.

[0278] Where A is an integer greater than or equal to 1.

[0279] The wireless frame number, also known as the system frame number, ranges from 0 to 1023.

[0280] In some embodiments, A can be obtained in several ways. One possible implementation is to obtain A from system messages configured for the UE. Another possible implementation is that A is related to Ns and N1, where N1 represents the total number of paging opportunities corresponding to the PEI, and A can be determined based on N1 and Ns.

[0281] In one embodiment of this disclosure, the above A satisfies: A = (Ceil(N1 / Ns)), where Ceil represents rounding up.

[0282] In some embodiments, when A is an integer greater than 1, the interval between the A PFs corresponding to PEI is less than the first threshold.

[0283] The first threshold represents the critical value of the number of radio frames or paging frames between the A PFs corresponding to the PEI.

[0284] The first threshold is related to T and N.

[0285] The first threshold can be obtained in several ways. For example, it can be obtained from the system messages configured for the UE. That is, the first threshold is included in the system messages configured by the base station for the UE. Another example is that the first threshold can be obtained according to communication protocol standards.

[0286] In some embodiments, the interval between the A PFs can refer to the interval between the A PFs, or it can refer to the interval between the first PF and the last PF corresponding to a PEI.

[0287] In one embodiment of this disclosure, a possible implementation of determining the target PF based on paging parameters is as follows: determining a first index based on paging parameters, wherein the first index is used to determine the target PF, and the first index is determined based on intermediate values ​​Y and A, wherein the intermediate value Y is related to SFN_PF, N, and T.

[0288] In some embodiments, the UE may determine the first index corresponding to each PF based on the intermediate values ​​Y and A, and may agree in the communication protocol standard to use the PF with the first index value as the target PF.

[0289] The first value can be any integer from 0 to A-1. In other words, the communication protocol standard can stipulate that the PF corresponding to any value of the first index from 0 to A-1 is the target PF.

[0290] In other embodiments, the UE can determine the first index corresponding to each PF based on the intermediate values ​​Y and A, and can also broadcast a system message to notify that the PF with the first index value being a first value is the target PF. The first value can be any integer from 0 to A-1. The UE broadcasts a system message to notify that the PF with the first index value being any value from 0 to A-1 is the target PF.

[0291] In some embodiments, the first value can be 0. That is, it can be agreed that the PF with a first index of 0 is the target PF, i.e., the first PF among A PFs can be the target PF.

[0292] In some embodiments, the first index, Y, and A satisfy: first index = Y mod A, where mod represents the remainder.

[0293] In one embodiment of this disclosure, the above Y satisfies: Y = floor(SFN_PF*N / T), where floor represents rounding down.

[0294] It is understood that in some embodiments, the first index PF_Index satisfies the following formula: PF_Index=(floor(SFN_PF*N / T))mod A.

[0295] In one embodiment of this disclosure, a possible implementation of determining the resource location of the PEI based on the target paging frame PF is as follows: A reference frame corresponding to the PEI is determined based on the target PF and a first offset value, wherein the first offset value represents the offset between the target PF and the reference frame, and the target PF, the first offset value, and the reference frame satisfy the following relationship: (SFN_PEI + PEI_offset)mod T = SFN_OPF, or SFN_PEI + PEI_offset = SFN_OPF, where SFN_PEI represents the radio frame number of the reference frame, PEI_offset represents the first offset value, SFN_OPF represents the radio frame number corresponding to the target PF, and mod represents the remainder; the resource location of the PEI is determined based on the reference frame.

[0296] It is understandable that the aforementioned first offset value can be a frame-level offset, a slot-level offset, or a symbol-level offset.

[0297] In this embodiment, the first offset is preferably a frame-level offset. For example, the system message configures the first offset to be one or two radio frames.

[0298] In one embodiment of this disclosure, an exemplary implementation of determining the resource location of a PEI based on a reference frame is as follows: A second index PEI_i_s corresponding to the PEI in the reference frame is determined, where PEI_i_s satisfies: PEI_i_s = (floor(UE_ID / N)mod Ns)modX, where N1 represents the total number of paging opportunities corresponding to the PEI; X represents the total number of PEIs corresponding to the reference frame; UE_ID represents the identifier of the UE; and mod represents the modulo operation. Based on the second index, a target value corresponding to the second index is determined from X second offset values, and the resource location of the PEI is determined based on the reference frame and the target value.

[0299] In one embodiment of this disclosure, the aforementioned X can be obtained in various ways. For example, X may be included in a system message configured for the UE. Alternatively, X may be related to Ns and N1, and may be determined based on Ns and N1.

[0300] In one embodiment of this disclosure, the above X satisfies: X = Ceil(Ns / N1), where Ceil represents rounding up.

[0301] In one embodiment of this disclosure, the value of X can be 1, 2, or 4. That is, X = 1, 2, or 4.

[0302] The second offset can be a frame-level offset, a slot-level offset, or a symbol-level offset. In this embodiment, the second offset is preferably a symbol-level offset.

[0303] In an exemplary embodiment of this disclosure, after determining the reference frame corresponding to the PEI, the base station needs to determine the specific temporal location of the PEI based on the starting point of the reference frame. The specific temporal location of the PEI can be determined by a second offset value. The base station can configure the second offset through a second parameter in the system message. Specifically, the second parameter can include at least one second offset, that is, the second parameter includes at least one numerical value, each numerical value corresponding to a second offset value. The second parameter can be represented as the first PDCCH monitoring time, firstPDCCH-MonitoringOccasionOfPEI-O. When the reference frame corresponds to 1 PEI, firstPDCCH-MonitoringOccasionOfPEI-O can be configured with 1 numerical value; when the reference frame corresponds to 2 PEIs, firstPDCCH-MonitoringOccasionOfPEI-O can be configured with 2 numerical values; when the reference frame corresponds to 4 PEIs, firstPDCCH-MonitoringOccasionOfPEI-O can be configured with 4 numerical values. When a reference frame corresponds to multiple PEIs, the base station needs to determine which value in firstPDCCH-MonitoringOccasionOfPEI-O corresponds to the PEI that the UE needs to listen to. At this time, the base station can determine the target value based on the second index. The target value is the value of the second bias value corresponding to the PEI that the UE listens to among X values.

[0304] It can be understood that the aforementioned second index determines the target index of the PEI within at least one PEI index included in the reference frame. This target index can be used to determine the specific resource location of the PEI within the reference frame. For example, if the reference frame includes two PEIs, then the "firstPDCCH-MonitoringOccasionOfPEI-O" configured by the base station for the UE includes two values: the resource location of the PEI corresponding to PEI_i_s = 0 is determined according to the first value in "firstPDCCH-MonitoringOccasionOfPEI-O", and the resource location of the PEI corresponding to PEI_i_s = 1 is determined according to the second value in "firstPDCCH-MonitoringOccasionOfPEI-O".

[0305] The following describes in more detail the process of determining the resource location of the PEI based on the second index, given that the reference frame is determined:

[0306] The base station determines the PEI's PDCCH listening opportunity based on the paging search space and the first PDCCH listening opportunity configured in the "DownlinkConfigCommonSIB" field of the downlink configuration System Information Block (SIB), namely "firstPDCCH-MonitoringOccasionOfPEI-O", and the total number of paging PDCCH MOs corresponding to a Synchronization Signal Block (SSB), namely "nrofPDCCHMonitoringOccasionPerSSB-InPO". When the paging search space is configured with "SearchSpaceId=0", the PEI's PDCCH listening opportunity is the same as that of the Remaining Minimum SI (RMSI).

[0307] When the "SearchSpaceId" configured in the paging search space configuration is not equal to 0, the base station determines that the UE needs to listen to the (PEI_i_s+1)th PEI. PEI is a set of "S*X1" consecutive PDCCH listening opportunities, where S is the number of SSBs actually transmitted based on the SSB location information carried by SIB1, and X1 represents the total number of paging PDCCH MOs corresponding to each SSB configured in "nrofPDCCHMonitoringOccasionPerSSB-InPO". If this value is not configured, X1 equals 1. When “firstPDCCH-MonitoringOccasionOfPEI-O” is configured, the first PDCCH monitoring time of the (PEI_i_s+1)th PEI is the (PEI_i_s+1)th value of the second parameter “firstPDCCH-MonitoringOccasionOfPEI-O” configured by the higher layer; otherwise, the first PDCCH monitoring time of the (PEI_i_s+1)th PEI is equal to PEI_i_s*S*X1.

[0308] Step 1002: Send a PEI at the resource location, where the PEI is used to indicate the presence of paging.

[0309] In one embodiment of this disclosure, the PEI can be used to indicate at least one of the following: whether paging DCI (Downlink Control Information) exists at the PO, or whether paging DCI is detected at the PO, or whether a paging message is detected, or whether it is necessary to wake up to detect a paging message during the current paging cycle; or paging messages exist at the PO, or paging DCI is detected at the PO, or a paging message is detected, or it is necessary to wake up to detect a paging message during the current paging cycle.

[0310] In some embodiments of this disclosure, the PEI described above may indicate the presence of a paging message at at least one paging time corresponding to the PEI.

[0311] It should be noted that the resource location of the PEI determined by the base station and the UE is consistent. Correspondingly, the base station transmits the PEI at the resource location corresponding to the PEI. The UE receives the PEI at this resource location and determines the presence of paging messages on the paging time PO that it needs to listen for based on the PEI. Based on the presence of paging messages on the paging time, the UE determines whether to enter a low-power or sleep state.

[0312] The transmission method of this disclosure accurately determines the target PF from the PF corresponding to the PEI by combining paging parameters, and accurately determines the resource location of the PEI based on the target PF, and transmits the PEI at the resource location. Thus, the base station can accurately determine the resource location of the PEI and accurately transmit the PEI based on the resource location.

[0313] Figure 11 This is a flowchart illustrating another transmission method provided according to an embodiment of the present disclosure, which is executed by a base station.

[0314] like Figure 11 As shown, the method may include:

[0315] Step 1101: Determine the resource location of PEI based on the PEI time window.

[0316] In this embodiment, the aforementioned resource location refers to the time-domain location corresponding to the PEI monitored by the user equipment (UE) communicating with the base station. When the PEI is a PDCCH-based PEI, the time-domain location corresponding to the PEI is the time-domain location corresponding to the first PDCCH monitoring time of the PDCCH-based PEI.

[0317] In this embodiment, the resource location of PEI refers to the resource location of the PEI that the UE communicating with the base station needs to listen to.

[0318] In some embodiments, one possible implementation of determining the resource location of PEI based on the PEI time window is: the starting resource location for UE to listen to PEI can be determined based on the starting location of the PEI time window, and the resource location for UE to listen to PEI is located inside the PEI time window.

[0319] Step 1102: Receive PEI at the resource location, where PEI is used to indicate the presence of paging.

[0320] For details on the specific implementation of step 1102, please refer to the relevant descriptions in the above embodiments, which will not be repeated here.

[0321] The paging advance indication transmission method of this disclosure, combined with the time window of the PEI, accurately determines the resource location of the PEI and transmits the PEI at that resource location. This enables the base station to accurately determine the resource location of the PEI and transmit the PEI accurately based on that resource location.

[0322] Figure 12 This is a schematic flowchart of a transmission method provided according to an embodiment of the present disclosure, which is executed by a base station.

[0323] like Figure 12As shown, the method may include:

[0324] Step 1201: Determine the resource location of the PEI based on the time window of the target paging frame PF and PEI.

[0325] In some embodiments, the time window of the PEI mentioned above may include at least one DRX cycle.

[0326] For each DRX cycle, the resource location of PEI can be determined based on the target PF in that DRX cycle and the target PF.

[0327] The target PF is determined based on the paging parameters.

[0328] For details on the specific implementation of determining the target PF based on paging parameters, please refer to the relevant descriptions in the above embodiments, which will not be repeated here.

[0329] The paging parameters mentioned above may include at least one of the following:

[0330] Discontinuous reception DRX period T; or

[0331] The total number of PFs N in each DRX cycle; or

[0332] The total number of paging opportunities (POs) in each PF, Ns; ​​or

[0333] The wireless frame number SFN_PF corresponds to PF; or

[0334] The first parameter A represents the total number of PFs corresponding to PEI.

[0335] The target PF is one of the A PFs corresponding to PEI.

[0336] Where A is an integer greater than or equal to.

[0337] The wireless frame number, also known as the system frame number, ranges from 0 to 1023.

[0338] In some embodiments, A can be obtained in several ways. One possible implementation is to obtain A from system messages configured for the UE. Another possible implementation is that A is related to Ns and N1, where N1 represents the total number of paging opportunities corresponding to the PEI, and A can be determined based on N1 and Ns.

[0339] The UE mentioned above refers to the UE that communicates with the base station.

[0340] In one embodiment of this disclosure, the above A satisfies: A = (Ceil(N1 / Ns)), where Ceil represents rounding up.

[0341] In some embodiments, when A is an integer greater than 1, the interval between the A PFs corresponding to PEI is less than the first threshold.

[0342] The first threshold represents the critical value of the number of radio frames or paging frames between the A PFs corresponding to the PEI.

[0343] The first threshold is related to T and N.

[0344] The first threshold can be obtained in several ways. For example, it can be obtained from the system messages configured for the UE. That is, the first threshold is included in the system messages configured for the UE. Another example is that the first threshold can be obtained according to communication protocol standards.

[0345] In some embodiments, the interval between the A PFs can refer to the interval between the A PFs, or it can refer to the interval between the first PF and the last PF corresponding to a PEI.

[0346] For details on the specific implementation of determining the resource location of PEI based on the target PF, please refer to the description of the above embodiment, which will not be repeated here.

[0347] Based on the above description, it can be seen that in the technical solution of determining the resource location of the PEI by combining the time windows of the target paging frame PF and PEI, after determining the time window of the PEI, it can be achieved through... Figure 10 The method shown in the embodiment determines the resource location of PEI within a time window of PEI.

[0348] Step 1202: Receive PEI at the resource location, where the PEI is used to indicate the presence of paging.

[0349] For the specific implementation of step 1202, please refer to the relevant description in the above embodiments, which will not be repeated here.

[0350] The transmission method of this disclosure determines the resource location of the PEI based on the time window of the target paging frame PF and PEI, and transmits the PEI at that resource location. This enables the base station to accurately determine the resource location where the UE is listening for the PEI and transmit the PEI at that resource location.

[0351] For the PEI time window in any of the above embodiments, one possible implementation of determining the PEI time window is as follows: Figure 13 As shown, it may include:

[0352] Step 1301: Determine the PEI time window based on the third bias value and the start and end positions of the paging time window PTW corresponding to the user equipment (UE) communicating with the base station.

[0353] The third bias value represents the bias between the starting position of the PEI time window and the starting position of the PTW.

[0354] The paging time window (PTW) corresponding to the UE can be determined using existing technologies. One exemplary implementation for determining the PTW is as follows: the PTW is determined based on the UE's identification information and the extended discontinuous reception eDRX period corresponding to the UE.

[0355] It should be noted that the PTW window is at the UE level, and the PTW window may differ between different UEs. The PTW window is determined based on the PH (Programmable Context), the start position (PTW_start) of the PTW within the PH, and the end position (PTW_end) of the PTW.

[0356] The superframe number (H-SFN) to which PH resides satisfies the following relationship:

[0357] H-SFN mod TeDRX_CN=(UE_ID_H mod TeDRX_CN)

[0358] Where TeDRX_CN is the length of the eDRX period, which is in units of superframes, and 1 superframe equals 1024 radio frames; UE_ID_H is an identifier ID corresponding to the UE, and mod indicates the remainder.

[0359] The radio frame number (SFN) at which the PTW window begins (PTW_start) is located satisfies the following formula:

[0360] SFN = 128 * ieDRX_CN, where

[0361] ieDRX_CN=floor(UE_ID_H / TeDRX_CN)mod 8

[0362] The radio frame number (SFN) at the end position (PTW_end) of the PTW window satisfies the following formula:

[0363] SFN = (PTW_start + L * 100 - 1) mod 1024, where L is the configured PTW window length.

[0364] In one embodiment of this disclosure, a possible implementation of determining the PEI time window based on the third offset value, the start position and the end position of the paging time window PTW corresponding to the UE is as follows: determine the start position PTW_start_PEI of the PEI time window based on the start position of PTW and the third offset value.

[0365] In one embodiment of this disclosure, the end position of the PEI time window is determined based on the end position of the PTW. As an example, the end position of the PTW can be used as the end position of the PEI time window.

[0366] In another embodiment of this disclosure, one possible implementation of determining the PEI time window based on the third offset value, the start position and the end position of the paging time window PTW corresponding to the UE is as follows: determine the end position PTW_end_PEI of the PEI time window based on the end position of PTW and the third offset value.

[0367] In one embodiment of this disclosure, the start position of the PEI time window can be determined based on the start position of the PTW.

[0368] In another embodiment of this disclosure, one possible implementation of determining the PEI time window based on the third offset value, the start position and the end position of the paging time window PTW corresponding to the UE is as follows: the start position of the PEI time window PTW_start_PEI is determined based on the start position of PTW and the third offset value; the end position of the PEI time window PTW_end_PEI is determined based on the end position of PTW and the third offset value.

[0369] In one embodiment of this disclosure, PTW_start_PEI satisfies: PTW_start_PEI = PTW_start – PEI_offset3, or (PTW_start_PEI + PEI_offset3) mod first preset value = PTW_start, where PTW_start represents the starting position of PTW, PEI_offset3 represents the third offset value, and mod represents the remainder.

[0370] In one embodiment of this disclosure, the first preset value is 1024.

[0371] In one embodiment of this disclosure, PTW_end_PEI satisfies: PTW_end_PEI = PTW_end – PEI_offset3, or (PTW_end_PEI + PEI_offset3) mod the second preset value = PTW_end, where PTW_end represents the end position of PTW, PEI_offset3 represents the third offset value, and mod represents the remainder.

[0372] In one embodiment of this disclosure, the second preset value is 1024.

[0373] In one embodiment of this disclosure, when the system frame number corresponding to the start position of PTW is greater than or equal to the third offset value, PTW_start_PEI satisfies: PTW_start_PEI = PTW_start – PEI_offset3; PTW_end_PEI satisfies: PTW_end_PEI = PTW_end – PEI_offset3.

[0374] In another embodiment of this disclosure, when the system frame number corresponding to the end position of PTW is less than the third offset value, PTW_start_PEI satisfies: (PTW_start_PEI + PEI_offset3) mod the first preset value = PTW_start; PTW_end_PEI satisfies: (PTW_end_PEI + PEI_offset3) mod the second preset value = PTW_end.

[0375] In one embodiment of this disclosure, the third offset value is the same as the first offset value, wherein the first offset value represents the offset between the target PF and the reference frame corresponding to the PEI.

[0376] In one embodiment of this disclosure, the target PF, the first offset value, and the reference frame satisfy the following relationship: (SFN_PEI + PEI_offset)mod T = SFN_OPF, or SFN_PEI + PEI_offset = SFN_OPF, where SFN_PEI represents the radio frame number of the reference frame, PEI_offset represents the first offset value, SFN_OPF represents the radio frame number corresponding to the target PF, and mod represents the remainder.

[0377] In one embodiment of this disclosure, the superframe number corresponding to PEI is the same as the superframe number corresponding to PF, or the superframe number corresponding to PEI is equal to the superframe number corresponding to PF minus a third preset value.

[0378] In one embodiment of this disclosure, the third preset value is 1 or 1024. That is, PH_PEI and PH satisfy the following formula: PH_PEI = PH - 1, or PH_PEI = PH - 1024, where PH_PEI represents the superframe number corresponding to PEI, and PH represents the superframe number corresponding to PF.

[0379] In one embodiment of this disclosure, when the system frame number corresponding to the starting position of PTW is greater than or equal to the third offset value, H_PEI = PH, where PH_PEI represents the superframe number corresponding to PEI and PH represents the superframe number corresponding to PF.

[0380] In another embodiment of this disclosure, when the system frame number corresponding to the starting position of PTW is less than the third offset value, PH_PEI and PH satisfy the following formula: PH_PEI = PH-1, or PH_PEI = PH-1024, where PH_PEI represents the superframe number corresponding to PEI and PH represents the superframe number corresponding to PF.

[0381] For the PEI time window in any of the above embodiments, another possible implementation of determining the PEI time window is: determining the PEI time window based on at least one of the third bias value, the start position of PTW, and the end position of PTW.

[0382] The third bias value represents the bias between the starting position of the PEI time window and the starting position of the PTW.

[0383] In one embodiment of this disclosure, in the technical solution of determining the resource location of PEI by combining the time windows of the target paging frame PF and PEI, the value of the third offset value in this technical solution is the same as the value of the first offset value, wherein the first offset value represents the offset value between the reference frame corresponding to the target PF and PEI.

[0384] Figure 14 This is a schematic diagram of the structure of a user equipment provided according to an embodiment of the present disclosure.

[0385] like Figure 14 As shown, the user equipment may include a transceiver 1400, a processor 1410, and a memory 1420, wherein:

[0386] Transceiver 1400 is used to receive and send data under the control of processor 1410.

The bus interface provides an interface. The transceiver 1400 can be multiple elements, including transmitters and receivers, providing units for communicating with various other devices over a transmission medium, including wireless channels, wired channels, optical fibers, and other transmission media.

For different user devices, the user interface 1430 may also be an interface that can connect to external or internal devices. The connected devices include, but are not limited to, keypad, display, speaker, microphone, joystick, etc.

[0389] Processor 1410 is responsible for managing the bus architecture and general processing, while memory 1420 can store data used by processor 1410 when performing operations.

[0391] The processor 1410 calls a computer program stored in memory and performs the following operations:

[0392] The resource location of the PEI is determined based on the time window of the target paging frame PF and / or the paging advance notice PEI, wherein the target PF is determined based on paging parameters, and the aforementioned paging parameters include at least one of the following:

[0393] Discontinuous reception DRX period T; or

[0394] The total number of PFs N in each DRX cycle; or

[0399] Optionally, the target PF is determined based on paging parameters, including:

[0400] Based on the paging parameters, a first index is determined, which is used to determine the target PF. The first index is determined based on the intermediate values ​​Y and A, and the intermediate value Y is related to SFN_PF, N, and T.

[0401] Optionally, the first index, Y, and A satisfy: first index = Y mod A, where mod means modulo.

[0402] Optionally, Y satisfies: Y = floor(SFN_PF*N / T), where floor represents rounding down.

[0403] Optionally, A is related to Ns and N1, where N1 represents the total number of paging opportunities corresponding to PEI.

[0404] Optionally, A satisfies: A = (Ceil(N1 / Ns)), where Ceil represents rounding up.

[0405] Optionally, the resource location of the PEI can be determined based on the target paging frame PF, including:
