Abstract
Description
Technical Field
[0001] The present invention relates to the field of communication technologies, and in particular to a method, apparatus, and device for transmitting a paging advance indication. Background Art
[0002] In 5G NR systems, power-saving designs for terminals are essential because 5G supports greater bandwidth, higher throughput, more complex services, and the corresponding more sophisticated processing technologies. Power-saving optimization can reduce terminal power consumption, extend battery life, and thus improve the user experience.
[0003] The prior art supports the use of a paging early indication (PEI) signal in the Radio Resource Control (RRC) idle state as an indicator of whether the physical downlink control channel (PDCCH) for scheduling paging messages needs to be monitored. Specifically, before receiving a paging message, the terminal first receives the PEI. If the PEI indicates that the terminal needs to receive subsequent paging messages, the terminal continues to receive the paging message. Otherwise, the terminal can enter a low-power or sleep state, thereby reducing the power consumption of the terminal. The prior art does not yet have a clear method for determining the resource location of the PEI to implement PEI transmission. Summary of the Invention

[0283] To make the technical problems, technical solutions, and advantages to be solved by the present invention more apparent, a detailed description will be given below with reference to the accompanying drawings and specific embodiments. In the following description, specific details such as specific configurations and components are provided solely to facilitate a comprehensive understanding of the embodiments of the present invention. Therefore, it should be clear to those skilled in the art that various changes and modifications may be made to the embodiments described herein without departing from the scope and spirit of the present invention. In addition, for the sake of clarity and brevity, descriptions of known functions and configurations have been omitted.
[0284] It should be understood that references throughout this specification to "one embodiment" or "an embodiment" mean that a particular feature, structure, or characteristic associated with the embodiment is included in at least one embodiment of the present invention. Therefore, the appearances of "in one embodiment" or "in an embodiment" throughout this specification do not necessarily refer to the same embodiment. Furthermore, these particular features, structures, or characteristics may be combined in any suitable manner in one or more embodiments.
[0285] In various embodiments of the present invention, it should be understood that the size of the serial numbers of the following processes does not mean the order of execution. The execution order of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the embodiments of the present invention.
[0286] In embodiments of the present invention, the term "and / or" describes the association relationship between associated objects, indicating that three possible relationships exist. For example, "A and / or B" can represent three situations: A exists alone, A and B exist simultaneously, and B exists alone. The character " / " generally indicates that the associated objects are in an "or" relationship.
[0287] In the embodiments of the present application, the term "plurality" refers to two or more than two, and other quantifiers are similar.
[0288] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.
[0289] When describing the embodiments of the present invention, some concepts used in the following description are first explained.
[0290] Paging message:
[0291] The paging message consists of two parts, namely the paging PDCCH and the paging physical downlink shared channel (PDSCH). To save power on the terminal, the paging reception of user equipment (UE) in the RRC idle (IDLE) and RRC inactive (INACTIVE) states in the New Radio (NR) must follow the discontinuous reception (DRX) principle.
[0292] The network can configure a paging cycle (DRX cycle) for the UE through higher-layer signaling (RRC signaling and / or core network signaling). System information also broadcasts a default DRX cycle. The UE determines the DRX cycle used for receiving paging based on the minimum value of the DRX cycle configured by higher-layer signaling and the default DRX cycle. The terminal monitors one PO in each DRX cycle.
[0293] A PO consists of a set of PDCCH monitoring opportunities (MO), which can include multiple time slots, such as subframes or orthogonal frequency division multiplex (OFDM) symbols. Paging downlink control information (DCI) is sent on the PDCCH MO.
[0294] A paging frame (PF) is a radio frame that can contain one or more POs or PO start points. In multi-beam operation, the UE assumes that all transmission beams repeatedly transmit the same paging message and short message. The UE is responsible for selecting the appropriate beam and receiving the paging and short messages.
[0295] The system frame number (SFN) corresponding to the paging frame can be determined according to the following formula:
[0296] (SFN+PF_offset)mod T=(T div N)*(UE_ID mod N)
[0297] Wherein, T represents the DRX cycle, whose unit is radio frame; N represents the total number of PFs in each DRX cycle; PF_offset represents the offset used to determine the paging frame; UE_ID = 5G-S-TMSI mod 1024, where 5G-S-TMSI is a 48-bit bit string.
[0298] Each paging frame contains Ns paging opportunities. The index of each PO is i_s, which is determined by the following formula:
[0299] i_s=floor(UE_ID / N)mod Ns
[0300] The parameters N, PF_offset, and Ns are signaled via the System Information Block (SIB1).
[0301] The UE determines the PDCCH monitoring opportunity for paging based on the paging search space, the first PDCCH monitoring opportunity ("firstPDCCH-MonitoringOccasionOfPO") configured in the "DownlinkConfigCommonSIB" field, and the number of PDCCH monitoring opportunities ("nrofPDCCHMonitoringOccasionPerSSB-InPO") per SSB. When the paging search space is configured with "SearchSpaceId = 0," the PDCCH monitoring opportunity is the same as the remaining minimum system information (RMSI).
[0302] When "SearchSpaceId = 0" is configured for the paging search space, Ns is 1 or 2. For Ns = 1, there is only one PO in the PF, and its starting point is the starting point of the first PDCCH monitoring opportunity. For Ns = 2, the PO is in the first half frame (i_s = 0) or the second half frame (i_s = 1) of the PF.
[0303] When the "SearchSpaceId" configured in the paging search space configuration is not equal to 0, the UE monitors the (i_s+1)th PO. The PO is a set of "S*X" consecutive PDCCH monitoring opportunities, where S is the number of synchronization signal blocks (SSBs) actually transmitted based on the location information of the synchronization signal and PBCH block (SSB) carried by SIB1, and X represents the number of PDCCH MOs corresponding to each SSB configured by "nrofPDCCHMonitoringOccasionPerSSB-InPO". If this value is not configured, X is equal to 1. Moreover, the [x*S+K]th paging PDCCH monitoring opportunity in the PO corresponds to the Kth transmitted SSB, where x = 0, 1, ..., X-1, K = 1, 2, ..., S. The PDCCH monitoring opportunities configured in the paging configuration do not overlap with uplink (UL) symbols and are numbered sequentially starting from 0 starting from the first paging MO in the PF. When "firstPDCCH-MonitoringOccasionOfPO" is configured, the starting point of the PDCCH MO of the (i_s+1)th PO is the (i_s+1)th value of the high-level parameter "firstPDCCH-MonitoringOccasionOfPO", otherwise, the starting point of the PDCCH MO of the (i_s+1)th PO is equal to i_s*S*X.
[0304] Specifically, the embodiment of the present invention provides a method, apparatus and device for transmitting a paging advance indication, which is used to determine the resource location of the PEI and thus realize the transmission of the PEI.
[0305] like Figure 1 As shown, an embodiment of the present invention provides a method for transmitting a paging advance indication, which specifically includes the following steps:
[0306] Step 11: The user equipment determines the resource location of the paging advance indication PEI according to at least one of the target synchronization signal block SSB, the target paging opportunity PO and the target paging frame PF, or according to the first frame number.
[0307] The target SSB is one of the multiple SSBs; the target PO is one of the multiple POs; and the target PF is one of the multiple PFs. When determining the resource location of the PEI, it can be determined based on a combination of one or more of the target SSB, target PO, and target PF. For example, the resource location of the PEI can be determined based on the target SSB, the resource location of the PEI can be determined based on the target PO, the resource location of the PEI can be determined based on the target PF, the resource location of the PEI can be determined based on the target SSB and target PO, and the resource location of the PEI can be determined based on the target SSB and target PO. Determining the resource location of the PEI based on the target SSB and target PO can be as follows: determining the target SSB based on the target PO, and determining the resource location of the PEI based on the target SSB; determining the resource location of the PEI based on the target SSB and target PF can be as follows: determining the target SSB based on the target PF, and determining the resource location of the PEI based on the target SSB.
[0308] Optionally, the first frame number is a frame number of a radio frame in which the PEI is located. In an embodiment, the user equipment may determine a resource location of the PEI based on the first frame number. The radio frame corresponding to the first frame number may include one or more PEIs, or a starting position of one or more PEIs.
[0309] Step 12: The user equipment receives or detects the PEI sent by the network side device at the resource location; wherein the PEI is used to indicate the presence of paging.
[0310] After the UE determines the resource location of the PEI, it receives or detects the PEI at the resource location. The PEI can be used to indicate the presence of paging, that is, whether paging occurs. For example, "1" indicates the presence of paging, and "0" indicates the absence of paging. The UE can determine whether to receive paging messages based on the PEI. When paging messages are not required, the UE can enter a low-power or sleep state, thereby reducing UE power consumption.
[0311] In an embodiment of the present application, the user equipment determines the resource location of the PEI based on one or more of the target SSB, target PO, and target PF, or determines the resource location of the PEI based on the first frame number, thereby receiving or detecting the PEI for indicating the presence of paging at the resource location, which can reduce the power consumption of the UE. Among them, by determining the resource location of the PEI through the SSB, the PEI can be closer to the SSB, and a greater power saving effect can be obtained at this time. The idle UE can receive the PEI immediately after receiving the SSB. When the PEI indicates that the UE has no paging, the UE can enter a low-power sleep state as soon as possible, thereby reducing power consumption. The embodiment of the present application also provides a method for determining the PEI resource location when one PEI corresponds to multiple POs or multiple PFs.
[0312] Optionally, the method further includes: determining at least one of the target SSB, the target PO and the target PF.
[0313] The following describes the methods for determining the target SSB, the target PO, and the target PF. It is worth noting that when determining multiple of the above three (such as the target SSB and the target PO), the steps are the same as those for determining them separately.
[0314] As an optional embodiment, determining the target SSB includes:
[0315] The target SSB is determined according to target parameters, wherein the target parameters include: target PO or target PF.
[0316] In this embodiment, the target SSB can be determined according to the target PO or target PF, that is, the resource location of PEI can be determined according to the target PO or target PF, or the target SSB can be determined according to the target PO or target PF, and the resource location of PEI can be determined according to the target SSB.
[0317] Specifically, determining the target SSB according to the target parameter may include:
[0318] The target SSB is determined according to the position of the target parameter and the distance between the target parameter and the target SSB; wherein the distance satisfies: being greater than the period of Y SSBs and less than or equal to the period of Y+Y1 SSBs, Y being the number of SSBs between the target SSB and the target parameter, and Y1≥1.
[0319] In this embodiment, the target SSB can be determined based on the position of the target PO or target PF and the distance between the target PO or target PF and the target SSB. Taking the target PO as an example, the distance satisfies:
[0320] Y*Period_SSB <PO_location–SSB_location≤(Y+1)*Period_SSB
[0321] Period_SSB represents the period of SSB, PO_location represents the location of the target PO (such as the frame number, subframe number, time slot number or OFDM symbol where the first MO of the target PO starts), and SSB_location represents the location of the target SSB (for example, the frame number, subframe number, time slot number or OFDM symbol where the start position or end position of the target SSB is located). PO_location–SSB_location represents the distance. Preferably, Y1=1, when Y1 is greater than 1, the distance is the maximum distance or minimum distance that meets the above conditions. At this time, the target SSB is the SSB that meets the maximum distance or minimum distance conditions. Y is a function related to the number of SSBs separated by the target SSB and the target parameter.
[0322] Optionally, the method for determining Y may include at least one of the following:
[0323] 1) System message configuration;
[0324] 2) Broadcast signaling configuration; for example: SIB-X configuration.
[0325] 3) Agreement;
[0326] 4) Determined according to a first interval; the first interval may be the minimum distance between the end position of the PEI and the target PO or target PF, and the first interval may be configured or determined according to other parameters.
[0327] 5) Determined according to the first offset; the first offset may be: the offset between the resource location of the target SSB, or the target PO, or the target PF and the resource location of the PEI.
[0328] 6) Determined according to the number of beams of the SSB; it should be noted that the SSB may include the target SSB or the non-target SSB, and the number of beams of the target SSB and the non-target SSB is the same.
[0329] 7) Determined according to the number of beams of the PEI.
[0330] In this embodiment, after determining the target SSB, the resource location of the PEI can be determined according to the target SSB, so that the terminal receives or detects the PEI at the resource location.
[0331] As an optional embodiment, a method of determining the target PO or the target PF may include one of the following:
[0332] (1) Determining the target PO or target PF based on a first parameter, where the first parameter includes at least one of the total number of PFs in each discontinuous reception (DRX) cycle (i.e., N), the number of POs contained in each PF (i.e., Ns), and a user equipment identifier (i.e., UE_ID). The UE may determine the target PO or target PF based on the paging parameters N, Ns, and UE_ID.
[0333] (2) Determine the target PO or target PF according to a second parameter, where the second parameter is the number of POs corresponding to one PEI; the UE may determine the target PO or target PF according to the second parameter, where the second parameter is used to indicate the number of POs corresponding to one PEI.
[0334] (3) Determine the target PO or target PF according to the PEI period.
[0335] (4) In the case where one PEI corresponds to one PO, the target PO is the PO that the user equipment needs to monitor, and the target PF is the PF corresponding to the PO that the user equipment needs to monitor.
[0336] In this embodiment, the target PO or the target PF is determined, and the resource location of the PEI can be directly determined based on the target PO or the target PF; or, the target SSB is determined based on the target PO or the target PF, and the resource location of the PEI is determined based on the target SSB.
[0337] Optionally, determining the resource location of the PEI according to at least one of the target SSB, the target PO, and the target PF includes:
[0338] The resource location of the PEI is determined based on the resource location of the target SSB, or the target PO, or the target PF, and a first offset; wherein the first offset is the offset between the resource location of the target SSB, or the target PO, or the target PF and the resource location of the PEI.
[0339] Among them, the first offset can be a network side configuration or a protocol agreement, that is, the interval between the fixed PEI and the target SSB, or the interval between the PEI and the target PO, or the interval between the PEI and the target PF.
[0340] Taking the target SSB as an example, a method for determining the first offset may include:
[0341] 1: The offset between the configured PEI and the target SSB: PEI_location = SSB_location + Offset; where PEI_location is the frame number, subframe number, time slot number or OFDM symbol of the start or end position of PEI; SSB_location is the frame number, subframe number, time slot number or OFDM symbol of the start position of the target SSB.
[0342] It should be noted that the first offset is less than the period length of the target SSB; or, the first offset is proportional to the period of the target SSB.
[0343] 2. The interval between the fixed PEI and the target SSB agreed upon by the protocol, for example, the PEI is located in the next slot of the target SSB.
[0344] Specifically, the resource location of the PEI may include at least one of the following:
[0345] The starting position of the PEI;
[0346] The end position of the PEI;
[0347] The monitoring start position of the PEI;
[0348] The monitoring end position of the PEI.
[0349] In this embodiment, the start position, end position, monitoring start position, and monitoring end position of the PEI may be determined according to one or more of the target SSB, the target PO, and the target PF. The start position or monitoring start position of the PEI may be determined first, and the end position or monitoring end position of the PEI may be determined according to the start position or monitoring start position.
[0350] As an optional embodiment, when the resource location of the PEI includes the start position of the PEI and / or the listening start position of the PEI, the end position of the PEI and / or the listening end position of the PEI are determined based on the start position of the PEI and / or the listening start position of the PEI, and the duration of the PEI.
[0351] The duration of the PEI can be a fixed time value configured by the network side or specified by the protocol. The end position of the PEI can be determined based on the start position and duration of the PEI; the end position of the PEI monitoring can be determined based on the start position and duration of the PEI monitoring.
[0352] It should be noted that, if the end position of the PEI or the end position of the monitoring is determined first, the start position of the PEI or the start position of the monitoring can also be determined according to the duration.
[0353] In an embodiment of the present application, after determining the resource location of the PEI based on one or more of the target SSB, target PO, and target PF, it is further possible to determine whether the determined resource location meets a predetermined condition. If the condition is met, the PEI can be received or detected at the determined resource location. This will be described in detail below.
[0354] As an optional embodiment, the method further includes:
[0355] Determine whether the resource location satisfies a first condition; if the first condition is not satisfied, update the resource location to: the difference between the resource location and the SSB period.
[0356] Optionally, the first condition includes: a distance between the resource location and the resource location of the target PO or target PF is greater than or equal to a first interval.
[0357] The first interval is the minimum value of the distance between the resource location of the PEI (preferably the end location or the listening end location) and the target PO or target PF. The resource location of the target PO or target PF can be the location of the first MO of the target PO or the starting location of the target PO, or the ending location of the target PO.
[0358] In this embodiment, when determining whether the resource location satisfies the first condition, the end position or the monitoring end position in the resource location may be judged. For example, the end position satisfies the condition: PO_location - PEI_end ≥ min_gap, where min_gap is the first interval, which may be configured by the network or reported by the UE.
[0359] When the resource location of the PEI meets the first condition, the step of receiving or detecting the PEI sent by the network-side device at the resource location in step 12 can be performed. When the resource location of the PEI does not meet the first condition, the resource location that needs to be updated is: the difference between the resource location (i.e., the resource location determined in step 11) and the SSB period, that is, the resource location is updated to PEI_location-Period_SSB. That is, when the network-side device configures or agrees on Y according to the system message or broadcast signaling or the protocol, the UE calculates and updates Y according to min_gap, and updates Y to Y+1.
[0360] As an optional embodiment, the PEI includes X beams, and the resource location of the PEI includes: X resource locations corresponding to the PEIs of the X beams;
[0361] The receiving or detecting the PEI at the resource location may include: when a first resource location among the X resource locations overlaps with the resource location of the first signal, receiving or detecting the PEI at a second resource location; wherein the second resource location is the first resource location after the first resource location.
[0362] The first resource position is, for example, the Kth resource position among the X resource positions. The first signal may include: at least one of: an SSB, a channel state information reference signal (CSI-RS), a time-frequency tracking reference signal (TRS), a PDCCH, a PDSCH, and a demodulation reference signal (DMRS).
[0363] Taking the first signal as an SSB or TRS signal as an example, when the Kth resource position among multiple resource positions completely or partially overlaps with the resource position where the SSB, TRS and other signals are located, the Kth resource position is an invalid PEI resource position, and the K+1th resource position is used to transmit the PEI of the Kth beam, that is, the invalid PEI resource position can be discarded or skipped, and the valid PEI resource position is postponed.
[0364] As an optional embodiment, for the method of determining the resource location of the PEI according to the first frame number, the method further includes:
[0365] The first frame number is determined, where the first frame number is the frame number of the radio frame where the PEI is located. The user equipment determines the first frame number, that is, determines the frame number of the radio frame where the PEI is located. The first frame number can be represented by PEI_SFN.
[0366] Optionally, the method further comprises: determining a first index, the first index being an index of the PEI;
[0367] Determining the resource location of the paging advance indication PEI according to the first frame number may include: determining the resource location of the PEI according to the first frame number and the first index.
[0368] In this embodiment, the first index is an index of the PEI, which may be an index of the PEI in at least one PEI included in the radio frame where the PEI is located. The first index may be represented by PEI_i_s. For example, when the radio frame corresponding to the first frame number includes one PEI, PEI_i_s=0; when the radio frame corresponding to the first frame number includes two PEIs, PEI_i_s=0 or 1.
[0369] In an embodiment of the present application, determining, by the user equipment, the resource location of the PEI based on the first frame number may include: determining the resource location of the PEI based only on the first frame number; or determining the resource location of the PEI based on the first frame number and a first index. For example, when the radio frame corresponding to the first frame number includes only one PEI, the resource location of the PEI may be determined based only on the first frame number; when the radio frame corresponding to the first frame number includes multiple PEIs, the resource location of the PEI may be determined using both the first frame number and the first index.
[0370] Optionally, determining the first frame number includes: determining the first frame number based on a third parameter, the third parameter including: the second interval (PEI_offset), the offset of the paging frame (PF_offset), the DRX cycle (T), the total number of PFs in each DRX cycle (N), the number of POs contained in each PF (Ns), the number of POs corresponding to a PEI (X), and at least one of the user equipment identifier (UE_ID).
[0371] The second interval is used to determine the first frame number, and the second interval can be used to describe the radio frame interval between the first frame number and the frame number where the PO is located (i.e., PF). The paging frame offset is used to determine the PF offset. The first frame number can be determined based on one or more of the third parameters.
[0372] Optionally, the first frame number is related to the product of a fourth parameter, a fifth parameter, and a sixth parameter. The fourth parameter is related to at least one of the DRX cycle and the total number of PFs within each DRX cycle. Optionally, if the fourth parameter is related to the DRX cycle (T) and the total number of PFs within each DRX cycle (N), the fourth parameter may satisfy (T div N).
[0373] The fifth parameter is related to at least one of the user equipment identifier, the total number of PFs in each DRX cycle, and the sixth parameter.
[0374] The sixth parameter is related to at least one of the number of POs corresponding to a PEI and the number of POs contained in each PF.
[0375] Optionally, if the sixth parameter is related to the number of POs corresponding to a PEI (X) and the number of POs contained in each PF (Ns), the sixth parameter (A) may satisfy: A = max(X / Ns, 1), that is, taking the maximum value between X / Ns and 1; or, the sixth parameter (A) may satisfy: A = max(floor(X / Ns), 1), that is, taking the maximum value between floor(X / Ns) and 1, where floor means rounding down.
[0376] If the fifth parameter is related to the user equipment identifier (UE_ID), the total number of PFs in each DRX cycle (N), and the sixth parameter (A), the fifth parameter may satisfy: floor((UE_ID mod N) / A).
[0377] Specifically, a modulo operation result of the sum of the first frame number, the second interval, and the offset of the paging frame, and the DRX cycle is equal to the product of the fourth parameter, the fifth parameter, and the sixth parameter.
[0378] Taking the fourth parameter satisfying (T div N), the fifth parameter satisfying floor((UE_ID mod N) / A), and the sixth parameter satisfying A=max(X / Ns, 1) or A=max(floor(X / Ns), 1) as an example, the first frame number satisfies the following formula:
[0379] (PEI_SFN+PF_offset+PEI_offset)mod T
[0380] =(T div N)*floor((UE_ID mod N) / A)*A
[0381] Among them, PEI_SFN is the frame number of the wireless frame where PEI is located (i.e., the first frame number); PF_offset is the offset used to determine PF; PEI_offset is the offset used to determine PEI_SFN; T is the DRX cycle; N is the total number of PFs in each DRX cycle; Ns is the number of POs contained in each PF; X is the number of POs corresponding to 1 PEI; UE_ID is 5G-S-TMSImod 1024.
[0382] It should be noted that PF_offset, T, N, and Ns may be paging parameters configured by the network device. PEI_SFN may be configured by the network device or agreed upon by the protocol, and this embodiment does not limit this. PEI_offset describes the radio frame interval between the PEI frame number (PEI_SFN) and the PO frame number (PF), and its unit is radio frames. X may be configured by the network device or agreed upon by the protocol, and this embodiment does not limit this.
[0383] As an optional embodiment, determining the first index may include:
[0384] Method (a): Determine the first index according to a seventh parameter, where the seventh parameter includes at least one of: a user equipment identifier (UE_ID), a total number of PFs in each DRX cycle (N), a number of POs contained in each PF (Ns), and a number of POs corresponding to a PEI (X);
[0385] or
[0386] Method (b): Determine the first index based on the PO index (i_s), the number of POs contained in each PF (Ns), and the number of POs corresponding to a PEI (X). The PO index may be the index of the PO received or detected by the user equipment.
[0387] In this embodiment, the user equipment determines a first index, that is, an index of the PEI in the first frame number, or an index of the PEI in at least one PEI included in the radio frame where the PEI is located. The first index can be represented by PEI_i_s. For the above method (a), if the seventh parameter includes: a user equipment identifier (UE_ID), a total number of PFs in each DRX cycle (N), a number of POs contained in each PF (Ns), and a number of POs corresponding to a PEI (X), then the first index can satisfy:
[0388] PEI_i_s=(floor(UE_ID / N)mod Ns)mod B
[0389] Among them, PEI_i_s is the first index, which can also be expressed as the index of one or more PEIs contained in the wireless frame corresponding to the first frame number of PEI; N is the total number of PFs in each DRX cycle; Ns is the number of POs contained in each PF; X is the number of POs corresponding to 1 PEI; B = max(Ns / X, 1) or B = max(floor(Ns / X), 1); UE_ID is 5G-S-TMSI mod 1024.
[0390] T, N, and Ns may be paging parameters configured by the network side device, and X may be configured by the network side device or may be a protocol agreement, which is not limited in this embodiment.
[0391] For the method (b), that is, the first index can be determined based on the index of the PO (i_s), the number of POs contained in each PF (Ns), and the number of POs corresponding to a PEI (X), then the first index can satisfy:
[0392] PEI_i_s=i_s mod B
[0393] Where PEI_i_s is the first index, i_s is the i_s corresponding to the PO determined by the user equipment, X is the number of POs corresponding to one PEI, Ns is the number of POs contained in each PF, and B = max(Ns / X, 1) or B = max(floor(Ns / X), 1).
[0394] In this embodiment, when the user equipment determines the resource location of the PEI, it can be determined based on the first frame number, wherein it can be determined based only on the first frame number, or based on the first frame number and the first index. For the user equipment, this determination method is simple and has less impact on the protocol.
[0395] It should be noted that the network side device can also determine the resource location of the PEI based on at least one of the target SSB, target PO, and target PF, or based on the first frame number, thereby sending the PEI at the determined resource location, so that the UE receives or detects the PEI at the determined resource location. The method for the UE to determine the resource location of the PEI is also applicable to the network side device and will not be repeated here.
[0396] The following describes the process of the method for transmitting the paging advance indication of the present application through specific embodiments.
[0397] Example 1: Taking the determination of the resource location of the paging advance indication PEI by the target SSB and the determination of the target SSB by the target PO as an example, in this embodiment, the start position or end position of the PEI is determined according to the target SSB.
[0398] Step 1: Determine the target PO and determine the target SSB based on the target PO.
[0399] The following is an explanation of two scenarios: Scenario 1 is for a PO-dense scenario; Scenario 2 is for a PO-sparse scenario.
[0400] Solution 1: Ns=4, N=T (PO-intensive scenario).
[0401] (1) Determine the target PO. The UE determines the target PO among multiple POs of the network-side device. This can be done in the following ways:
[0402] Method 1: The UE determines the Target PO based on the paging parameters N and Ns;
[0403] N represents the number of paging frames in a DRX cycle, and Ns represents the number of POs in a paging frame. Therefore, when the values of N and Ns are relatively large, it means that the POs are dense in the DRX cycle.
[0404] One possible implementation is: Target PO is one of X POs, where the value of X is related to paging parameters N and Ns. For example, when Ns and N are relatively large, X is large; when N and Ns are relatively small, X is small.
[0405] The UE determines parameter 0 corresponding to each PO of the network side device, such as: parameter 0 = PO_Index mod X, where PO_Index = SFN_PF*N*Ns / T+i_s, PO_Index represents the index of the PO in the DRX cycle. The parameter 0 can be the index of the PO in X POs.
[0406] Optionally, the PO_Index can also be expressed as:
[0407] PO_Index=floor(SFN_PF*N*Ns / T)+i_s
[0408] That is, the parameter 0 is expressed as: parameter 0 = (floor (SFN_PF*N*Ns / T) + i_s) mod X.
[0409] Wherein: SFN_PF is the SFN where the PF corresponding to the PO is located; N is the number of PFs in a DRX cycle; Ns is the number of POs in a PF, T is the length of the DRX cycle, and i_s is the index of the PO in the corresponding PF.
[0410] It can be agreed that when parameter 0 is 0, the corresponding PO is the Target PO.
[0411] It should be noted that this embodiment is not limited to the PO corresponding to parameter 0 being 0 as the target PO. The protocol can predefine the target parameter to be 0, ..., and the PO corresponding to any one of X-1 as the target PO. Through the predefined method, the network-side device and the UE will not be ambiguous about parameter 0 corresponding to the target PO. It is also possible to broadcast a notification through a system message that the PO corresponding to parameter 0 being 0, ..., and any one of X-1 is the target PO, and this is not limited to this.
[0412] Method 2: The UE determines the Target PO based on the parameter X of X POs corresponding to one PEI broadcasted by the network side device;
[0413] The difference between this method 2 and the above method 1 is that the value of X is notified by the network side device through system messages or other broadcast signaling, and the network side device and UE determine the Target PO through the parameter X of X POs corresponding to 1 PEI broadcast.
[0414] Method 3: The UE determines the Target PO based on the PEI period;
[0415] The network-side device configures the PEI period through system messages or other broadcast signaling. For example, the protocol stipulates that the Target PO is the first PO corresponding to the first PF in each PEI period.
[0416] like Figure 2 As shown, the Target PO is one PO in every eight POs in the network-side device. Therefore, in this embodiment, the value of X is 8; Figure 2 The SSB period is 20ms. The method for determining X can be any of the three methods mentioned above.
[0417] Optionally, a Target PF may be determined. In this embodiment, a Target PO is preferably determined. For example, the UE determines the Target PF based on at least one of the paging parameter N and the UE_ID. The UE determines the Target PF based on a parameter X, where the parameter X indicates that one PEI corresponds to X POs. It should be noted that the UE may determine the Target PF based on the PEI period. The following describes a method for determining the Target PF using a specific embodiment, including:
[0418] Method 4: The UE determines the target PF based on the paging parameter N;
[0419] One possible implementation is: the Target PF is one of X1 PFs, where the value of X1 is related to the paging parameter N. For example, when N is large, the value of X1 is large, and when N is small, the value of X1 is small.
[0420] The UE determines parameter 1 corresponding to each PF of the network side device, such as: parameter 1 = PF_Index mod X1, where PF_Index = SFN_PF_1*N / T, PF_Index represents the index of the PF in the DRX cycle. The parameter 1 can be the index of the PF in X1 PFs.
[0421] Optionally, the PF_Index may also be expressed as:
[0422] PF_Index=floor(SFN_PF_1*N / T)
[0423] That is, the parameter 1 is expressed as: parameter 1 = (floor (SFN_PF_1*N / T)) mod X1.
[0424] Wherein: SFN_PF_1 indicates the SFN where the PF is located; N is the number of PFs in a DRX cycle; and T is the length of the DRX cycle.
[0425] It can be agreed that when parameter 1 is 0, the corresponding PF is the Target PF.
[0426] It should be noted that this embodiment is not limited to the PF corresponding to the parameter 1 value of 0 being the target PF. The protocol may predefine the PF corresponding to any one of the values of parameter 1 among 0, ..., and X1-1 as the target PF. Through the predefined method, the network-side device and the UE will not be ambiguous about the parameter 1 corresponding to the target PF. A system message broadcast may also be used to notify that the PF corresponding to any one of the values of parameter 1 among 0, ..., and X1-1 is the target PF, and this is not limited to this.
[0427] Method 5: The UE determines the Target PF based on the parameter X of X POs corresponding to one PEI broadcasted by the network side device;
[0428] The difference between this method 5 and the above-mentioned method 4 is that in this method 5, the value of X1 is related to the value of X. The value of X is notified by the network side device through a system message or other broadcast signaling. The network side device and the UE determine X1 through the parameter X of X POs corresponding to 1 PEI broadcast, for example, X1 = X / Ns, and the target PF is determined by X1 and method 4.
[0429] Method 6: The UE determines the Target PF based on the PEI period;
[0430] The network side device configures the PEI period through system messages or other broadcast signaling. For example, the protocol stipulates that the Target PF is the first PF in each PEI period. The above methods 1-3 are optional implementation methods for determining the target PO, and methods 4-6 are optional implementation methods for determining the target PF.
[0431] The UE can determine the Target SSB based on the Target PO / Target PF. This embodiment takes determining the Target SSB based on the Target PO as an example. The MIB message in the SSB carries frame number information. After synchronization, the UE can determine the frame number, slot, etc. of each SSB.
[0432] The distance between the target SSB and the target PO needs to be greater than the period of Y SSBs and less than or equal to the period of (Y+Y1) SSBs. Specifically, the number of frames between the target SSB and the target PO needs to be greater than the number of frames corresponding to the period of Y SSBs and less than or equal to the number of frames corresponding to the period of (Y+1) SSBs; or, the number of subframes between the target SSB and the target PO needs to be greater than the number of subframes corresponding to the period of Y SSBs and less than or equal to the number of subframes corresponding to the period of (Y+1) SSBs; or, the number of time slots between the target SSB and the target PO needs to be greater than the number of time slots corresponding to the period of Y SSBs and less than or equal to the number of time slots corresponding to the period of (Y+1) SSBs, or, the number of OFDM symbols between the target SSB and the target PO needs to be greater than the number of OFDM symbols corresponding to the period of Y SSBs and less than or equal to the number of OFDM symbols corresponding to the period of (Y+1) SSBs. That is, the target SSB satisfies:
[0433] Y*Period_SSB <PO_location–SSB_location≤(Y+1)*Period_SSB
[0434] Wherein, PO_location is the location of the target PO (for example, the frame number, subframe number, time slot number or OFDM symbol where the first MO of the target PO starts), and SSB_location is the location of the target SSB (for example, the frame number, subframe number, time slot number or OFDM symbol where the start or end position of the target SSB is located). PO_location–SSB_location represents the distance between the target SSB and the target PO. In this embodiment, Y1=1.
[0435] The following example illustrates that the number of frames between the target SSB and the target PO must be greater than the number of frames corresponding to a period of Y SSBs and less than or equal to the number of frames corresponding to a period of (Y+1) SSBs. The frame number (SFN_SSB) where the target SSB is located must meet the following requirements:
[0436] Y*Period_SSB <SFN_PO-SFN_SSB≤(Y+1)*Period_SSB
[0437] Among them, SFN_PO is the SFN where the PF corresponding to the Target PO is located, and SFN_SSB is the SFN where the Target SSB is located.
[0438] According to the above formula, the SSB that satisfies the formula can be obtained as the target SSB. The Y in the formula can be determined by the following method:
[0439] 1) System message or broadcast signaling SIB-X configuration Y, Y is the number of SSBs between the target SSB and the target PO interval.
[0440] 2) The agreement stipulates Y.
[0441] 3) Y is calculated and determined based on min_gap and / or Offset and / or the number of beams of SSB and / or the number of beams of PEI.
[0442] Solution 2: Ns = 1, N = T / 4 (PO sparse scenario).
[0443] The difference between Option 2 and Option 1 is the method of determining the Target PO.
[0444] Determine the Target PO. The UE determines the PO it monitors as the Target PO.
[0445] The frame number (SFN_PO) of the PF corresponding to the PO monitored by the UE itself is determined by the PF and "first PDCCH-MonitoringOccasionOfPO" and the subcarrier spacing. When the subcarrier spacing (SCS) is 15kHz, the frame number of the PF corresponding to the PO is:
[0446] PF+floor(firstPDCCH-MonitoringOccasionOfPO / 140).
[0447] like Figure 3 As shown, the Target PO is the PO that the UE determines to be monitored as the Target PO. The UE can also determine the PF where the PO that it monitors is located as the Target PF. Figure 3 The period of the SSB is 20ms. This embodiment takes the determination of the target PO as an example.
[0448] The UE may determine the Target SSB according to the Target PO / Target PF. This embodiment takes determining the Target SSB according to the Target PO as an example. This part of the solution is the same as the first solution and will not be described in detail here.
[0449] The above step 1 is to determine the target SSB. The following describes how to determine the resource location of PEI based on the target SSB.
[0450] Step 2: The terminal determines the resource location of the PEI based on the target SSB.
[0451] Optionally, the start position or end position of the PEI is determined according to the position of the Target SSB.
[0452] Among them, the PEI (i.e., the start position or end position of the PEI) and the Offset of the target SSB can be configured. The start position or end position of the PEI is determined by the position and Offset of the target SSB, for example, satisfying the following formula: PEI_location = SSB_location + Offset, wherein PEI_location is the frame number, subframe number, time slot number, or OFDM symbol where the start position or end position of the PEI is located. SSB_location is the frame number, subframe number, time slot number, or OFDM symbol where the start position of the target SSB is located.
[0453] Preferably, the length of the Offset is less than the period length of the SSB, and the Offset is greater than or equal to 0. In this case, the PEI is located behind the SSB, such as Figure 2 and Figure 3 The length of the Offset is less than the SSB cycle length to ensure:
[0454] Y*Period_SSB <SFN_PO-SFN_PEI≤(Y+1)*Period_SSB
[0455] Optionally, the Offset may also be a negative number, that is, the PEI is located in front of the SSB.
[0456] The value of Offset can also be related to the SSB period. When the SSB period is longer, the possible Offset values are more or larger. When the SSB period is shorter, the possible Offset values are fewer or smaller. In other words, the possible candidate Offset values are proportional to the SSB period.
[0457] The offset between the PEI (i.e., the start or end position of the PEI) and the target SSB can also be fixed, that is, the offset can be agreed upon by the protocol. For example, the PEI can be located in the first slot of the next frame of the frame containing the target SSB, or the PEI can be located in the slot after the slot containing the target SSB.
[0458] Optionally, the duration of the PEI may be configured or fixed, and the end position (or start position) of the PEI may be determined based on the start position (or end position) of the PEI and the duration of the PEI.
[0459] The distance between the end location of the PEI and the PO must be greater than or equal to the min_gap. For example, the following condition must be met: PO_location - PEI_end ≥ min_gap. The min_gap can be configured by the network or reported by the UE. Alternatively, the distance between the start location of the PEI and the PO must be greater than or equal to the min_gap.
[0460] If the start position or end position of the PEI does not meet the above conditions, the start position or end position of the PEI can be updated to PEI_location-Period_SSB. That is, when the network side device configures Y according to the system message or broadcast signaling or the protocol, the UE calculates the start position or end position of the PEI based on the min_gap to determine whether it meets the conditions to determine whether to update Y. When Y needs to be updated, it is updated to Y+1. The resource location of the updated PEI meets:
[0461] (Y+1)*Period_SSB <SFN_PO-SFN_PEI≤(Y+2)*Period_SSB
[0462] Step 3: The terminal receives or detects PEI at the resource location.
[0463] In NR, many signals are sent through different beams. PEI is likely to be the same as paging DCI, and PEI also has multiple PEI opportunities. The Kth PEI opportunity corresponds to the Kth SSB. At this time, the beam of PEI sent by the Kth PEI opportunity corresponds to the beam of SSB at the Kth SSB position, that is, the number of PEI opportunities is the same as the number of SSBs actually transmitted by SIB1. When PEI is a multi-beam PEI, the solution for determining the resource location of PEI in this embodiment includes determining multiple resource locations corresponding to the PEI of multiple beams (beam), such as the starting position of the above PEI is the starting position of the PEI of the first beam, and the ending position of PEI is the ending position of the PEI of the last beam. The duration of the above PEI includes the resource locations corresponding to the PEIs of multiple beams. The specific method of determining the resource locations corresponding to the PEIs of multiple beams in the duration of PEI is not limited in this embodiment of the application. Assume that numbering starts at the first PEI resource location in the PEI duration and that the PEI duration includes multiple PEI resource locations. When the Kth resource location among the multiple PEI resource locations completely or partially overlaps with the resource location where signals such as SSB and TRS are located, the Kth resource location becomes an invalid PEI resource location, and the K+1th PEI resource location is used to transmit the PEI of the Kth beam. In other words, the invalid PEI resource location is discarded or skipped, and the PEI originally transmitted at the invalid PEI resource location is postponed to the next valid PEI resource location for transmission.
[0464] Among them, in step three, the network side device sends a PEI signal at the resource location, and the corresponding behavior of step three on the UE side is that the UE receives the TRS / PEI signal at the resource location. It should be noted that whether the network side device will definitely send a PEI signal at the sending location depends on the specific function of the PEI signal. For example, if the PEI is used to indicate the presence of paging DCI at the PO, the network side device will only send PEI at the resource location when there is paging DCI at the PO. At this time, the UE will receive or detect PEI at the resource location of the determined PEI, and finally the UE receives PEI. When there is no paging DCI at the PO, the network side device will not send PEI at the determined resource location. At this time, the UE will receive or detect PEI at the resource location of the determined PEI, and finally the UE cannot receive PEI.
[0465] It should be noted that the PEI described in the present invention may be a DCI-based PEI (DCI-based PEI) or a sequence-based PEI (sequence-based PEI), and the sequence-based PEI may be a TRS-based PEI (TRS-based PEI) or a CSI-RS-based PEI (CSI-RS-based PEI) or a secondary synchronization signal (Secondary Synchronisation Signal, SSS)-based PEI (SSS-based PEI). The embodiment of the present application does not limit the specific form, specific type or specific format of the PEI.
[0466] In the embodiment of the present application, the PEI can be used to indicate at least one of the following:
[0467] Whether Paging DCI exists at PO;
[0468] Whether the PO monitors paging DCI;
[0469] Whether the PO monitors paging messages;
[0470] Whether it is necessary to wake up and monitor paging messages during this paging cycle;
[0471] The paging message exists at the PO;
[0472] Monitor paging DCI at the PO;
[0473] Monitor paging messages;
[0474] It is necessary to wake up and monitor paging messages during this paging cycle;
[0475] Availability of TRS;
[0476] Whether the Earthquake and Tsunami Warning System (ETWS) sends notification information;
[0477] System message update indication whether to send;
[0478] Indication of the beam tracking reference signal.
[0479] The steps of the network side device implementing the transmission method of the paging advance indication correspond to those of the user equipment and are not described in detail here.
[0480] Example 2: Taking the example of determining the resource location of PEI through target SSB and determining the target SSB through target PO, in this example, the monitoring start position of PEI is determined according to the target SSB.
[0481] Step 1: Determine the target PO and determine the target SSB based on the target PO.
[0482] The implementation of step 1 in the second embodiment is the same as that of step 1 in the first embodiment, and will not be described in detail here.
[0483] Step 2: The terminal determines the resource location of the PEI based on the target SSB.
[0484] Optionally, the monitoring start position of the PEI may be determined according to the position of the Target SSB.
[0485] The monitoring start position of the PEI and the offset of the target SSB can be configured. The monitoring start position of the PEI is determined by the position and offset of the target SSB. For example, the following formula is satisfied: PEI_location = SSB_location + Offset, where PEI_location is the frame number, time slot number, or OFDM symbol of the starting monitoring position of the PEI. SSB_location is the frame number, time slot number, or OFDM symbol of the starting position of the target SSB.
[0486] Preferably, the length of the Offset is less than the period length of the SSB, and the Offset is greater than or equal to 0. In this case, the PEI is located behind the SSB, such as Figure 4 and Figure 5 As shown, Figure 4 For a dense PO scenario, Ns = 4, N = T, and the SSB period is 20ms; Figure 5 For PO sparse scenarios, Ns = 1, N = T / 4, and the SSB period is 20ms. The length of the Offset is smaller than the SSB period to ensure:
[0487] Y*Period_SSB <SFN_PO-SFN_PEI≤(Y+1)*Period_SSB
[0488] Optionally, the Offset may also be a negative number, that is, the monitoring start position of the PEI is located before the SSB.
[0489] The value of Offset can also be related to the SSB period. When the SSB period is longer, the possible Offset values are more or larger. When the SSB period is shorter, the possible Offset values are fewer or smaller. In other words, the possible candidate Offset values are proportional to the SSB period.
[0490] The offset between the PEI monitoring start position and the target SSB can also be fixed, that is, the offset can be agreed upon by the protocol. For example, the PEI monitoring start position is located in the first slot of the next frame of the target SSB, or the PEI is located in the slot next to the slot where the target SSB is located.
[0491] Optionally, the search space (SS) set of PEI can be configured, for example Figure 4 and Figure 5 In the multiple search space set (Multiple SS Set) shown in FIG, the UE prepares to monitor the PEI from the monitoring start position of the PEI. The specific starting position of the PEI monitoring is indicated by the "monitoringSlotPeriodicityAndOffset" of the search space set.
[0492] Specifically, the monitoring end position of the PEI can be determined by the monitoring start position (PEI_location) and duration of the PEI, for example, PEI_end=PEI_location+duration. In this case, the duration is the duration of multiple search spaces under multiple beams.
[0493] The distance between the PEI monitoring end position (PEI_end) and the PO needs to be greater than or equal to min_gap, for example, the following condition needs to be met: PO_location-(PEI_location+duration)≥min_gap. The min_gap can be configured on the network side or reported by the UE.
[0494] If the monitoring end position of the PEI does not meet this condition, the monitoring start position of the PEI is updated to PEI_location-Period_SSB. That is, when the network device configures Y according to the system message or broadcast signaling or the protocol, the UE calculates whether the monitoring start position of the PEI meets the condition based on the min_gap to determine whether to update Y. If Y needs to be updated, Y is updated to Y+1. The new monitoring start position of the PEI meets:
[0495] (Y+1)*Period_SSB <SFN_PO-SFN_PEI≤(Y+2)*Period_SSB
[0496] Step 3: The terminal receives or detects PEI at the resource location.
[0497] In NR, many signals are sent through different beams. PEI is likely to be the same as paging DCI. PEI also has multiple PEI opportunities. The Kth PEI opportunity corresponds to the Kth SSB. At this time, the beam of PEI sent by the Kth PEI opportunity corresponds to the beam of SSB at the Kth SSB position, that is, the number of PEI opportunities is the same as the number of SSBs actually transmitted by SIB1. When PEI is a multi-beam PEI, the solution for determining the PEI resource location in the second embodiment includes determining multiple resource locations corresponding to the multi-beam PEI, such as the monitoring start position of the PEI is the monitoring start position of the 1st beam PEI. The duration of the PEI includes the resource locations corresponding to the PEIs of multiple beams. The specific method for determining the resource locations corresponding to the PEIs of multiple beams in the duration of the PEI is not limited in the embodiment of the present application. Assume that numbering starts at the first PEI resource location in the PEI duration and that the PEI duration includes multiple PEI resource locations. When the Kth resource location among the multiple PEI resource locations fully or partially overlaps with the resource locations of signals such as SSB and TRS, the Kth resource location becomes an invalid PEI resource location, and the K+1th PEI resource location is used to transmit the PEI of the Kth beam. In other words, the invalid PEI resource location is dropped or skipped. At this time, the PEI originally transmitted at the invalid PEI resource location is postponed to the next valid PEI resource location for transmission.
[0498] The steps of the network side device implementing the transmission method of the paging advance indication correspond to those of the user equipment and are not described in detail here.
[0499] Example 3: Taking the determination of the resource location of a PEI through a target PO as an example, in this example, the starting location or the ending location of a PEI is determined according to the target PO.
[0500] Step 1: Determine the target PO.
[0501] The following is an explanation of two scenarios: Scenario 1 is for a PO-dense scenario; Scenario 2 is for a PO-sparse scenario.
[0502] Solution 1: Ns=4, N=T (PO dense scenario). Figure 6 shown.
[0503] Determine the Target PO. The UE determines the Target PO among multiple POs of the network-side device. This can be done in the following ways:
[0504] Method 1: The UE determines the Target PO based on the paging parameters N and Ns;
[0505] N represents the number of paging frames in a DRX cycle, and Ns represents the number of POs in a paging frame. Therefore, when the values of N and Ns are relatively large, it means that the DRX cycle is PO-intensive.
[0506] One possible implementation is: Target PO is one of X POs, where the value of X is related to paging parameters N and Ns. For example, when Ns and N are relatively large, X is large; when N and Ns are relatively small, X is small.
[0507] The UE determines parameter 0 corresponding to each PO of the network side device, such as: parameter 0 = PO_Index mod X, where PO_Index = SFN_PF*N*Ns / T+i_s, PO_Index represents the index of the PO in the DRX cycle. The parameter 0 can be the index of the PO in X POs.
[0508] Optionally, the PO_Index can also be expressed as:
[0509] PO_Index=floor(SFN_PF*N*Ns / T)+i_s
[0510] That is, the parameter 0 is expressed as: parameter 0 = (floor (SFN_PF*N*Ns / T) + i_s) mod X.
[0511] Wherein: SFN_PF is the SFN where the PF corresponding to the PO is located; N is the number of PFs in a DRX cycle; Ns is the number of POs in a PF, T is the length of the DRX cycle, and i_s is the index of the PO in the corresponding PF.
[0512] It can be agreed that when parameter 0 is 0, the corresponding PO is the Target PO.
[0513] It should be noted that this embodiment is not limited to the PO corresponding to parameter 0 being 0 as the target PO. The protocol can predefine the PO corresponding to any value of the target parameter from 0, ..., and X-1 as the target PO. Through the predefined method, the network-side device and the terminal will not be ambiguous about parameter 0 corresponding to the target PO. A system message broadcast can also be used to notify that the PO corresponding to any value of parameter 0 from 0, ..., and X-1 is the target PO, and this is not limited to this.
[0514] Method 2: The UE determines the Target PO based on the parameter X of X POs corresponding to one PEI broadcasted by the network side device;
[0515] The difference between this method 2 and the above method 1 is that the value of X is notified by the network side device through system messages or other broadcast signaling, and the network side device and UE determine the Target PO through the parameter X of X POs corresponding to 1 PEI broadcast.
[0516] Method 3: The UE determines the Target PO based on the PEI period;
[0517] The network-side device configures the PEI period through system messages or other broadcast signaling. For example, the protocol stipulates that the Target PO is the first PO corresponding to the first PF in each PEI period.
[0518] Optionally, a Target PF may be determined. In this embodiment, a Target PO is preferably determined. For example, the UE may determine the Target PF based on at least one of the paging parameter N and the UE_ID. The UE may also determine the Target PF based on a parameter X, where the parameter X indicates that one PEI corresponds to X POs. The UE may also determine the Target PF based on the PEI period. The following describes a method for determining the Target PF using a specific embodiment, including:
[0519] Method 4: The UE determines the target PF based on the paging parameter N;
[0520] One possible implementation is: the Target PF is one of X1 PFs, where the value of X1 is related to the paging parameter N. For example, when N is large, the value of X1 is large, and when N is small, the value of X1 is small.
[0521] The UE determines parameter 1 corresponding to each PF of the network side device, such as: parameter 1 = PF_Index mod X1, where PF_Index = SFN_PF_1*N / T, PF_Index represents the index of the PF in the DRX cycle. The parameter 1 can be the index of the PF in X1 PFs.
[0522] Optionally, the PF_Index may also be expressed as:
[0523] PF_Index=floor(SFN_PF_1*N / T)
[0524] That is, the parameter 1 is expressed as: parameter 1 = (floor (SFN_PF_1*N / T)) mod X1.
[0525] Wherein: SFN_PF_1 indicates the SFN where the PF is located; N is the number of PFs in a DRX cycle; and T is the length of the DRX cycle.
[0526] It can be agreed that when parameter 1 is 0, the corresponding PF is the Target PF.
[0527] It should be noted that this embodiment is not limited to the PF corresponding to the parameter 1 value of 0 being the target PF. The protocol may predefine the PF corresponding to any one of the values of parameter 1 among 0, ..., and X1-1 as the target PF. Through the predefined method, the network-side device and the UE will not be ambiguous about the parameter 1 corresponding to the target PF. A system message broadcast may also be used to notify that the PF corresponding to any one of the values of parameter 1 among 0, ..., and X1-1 is the target PF, and this is not limited to this.
[0528] Method 5: The UE determines the Target PF based on the parameter X of X POs corresponding to one PEI broadcasted by the network side device;
[0529] The difference between this method 5 and the above-mentioned method 4 is that in this method 5, the value of X1 is related to the value of X. The value of X is notified by the network side device through a system message or other broadcast signaling. The network side device and the UE determine X1 through the parameter X of X POs corresponding to 1 PEI broadcast, for example, X1 = X / Ns, and the target PF is determined by X1 and method 4.
[0530] Method 6: The UE determines the Target PF based on the PEI period;
[0531] The network-side device configures the PEI period through system messages or other broadcast signaling. For example, the protocol stipulates that the Target PF is the first PF in each PEI period.
[0532] The above methods 1-3 are optional implementation methods for determining the target PO, and methods 4-6 are optional implementation methods for determining the target PF.
[0533] Solution 2: Ns = 1, N = T / 4 (PO sparse scenario), such as Figure 7 shown.
[0534] The difference between Option 2 and Option 1 is the method of determining the Target PO.
[0535] Determine the Target PO, and the UE determines that the PO it monitors is the Target PO.
[0536] The system frame number (SFN_PO) of the PF corresponding to the PO monitored by the UE is determined by the PF, "first PDCCH-MonitoringOccasionOfPO", and the subcarrier spacing. When the SCS is 15 kHz, the system frame number of the PF corresponding to the PO is:
[0537] PF + floor(firstPDCCH-MonitoringOccasionOfPO / 140).
[0538] Optionally, the UE can also determine that the PF where the PO it monitors is located is the Target PF. This embodiment preferably determines the target PO.
[0539] Step 2: The terminal determines the resource location of the PEI according to the target PO.
[0540] Optionally, determine the start position or end position of the PEI according to the position of the Target PO.
[0541] Among them, the Offset between the PEI (start position or end position of the PEI) and the target PO can be configured. The start position or end position of the PEI is determined by the position of the target PO and the Offset. For example, the system frame number (SFN_PEI) of the frame where the start / end position of the PEI is located needs to satisfy:
[0542] Y*Period_SSB < SFN_PO - SFN_PEI ≤ (Y + 1)*Period_SSB
[0543] That is: Y*Period_SSB < Offset ≤ (Y + 1)*Period_SSB. Among them, SFN_PO is the SFN of the PF corresponding to the Target PO.
[0544] Optionally, this Offset can also be negative, that is, the PEI is in front of the SSB.
[0545] The value of the Offset can also be related to the period of the SSB. When the period of the SSB is larger, the possible values of the Offset are more or larger; when the period of the SSB is smaller, the possible values of the Offset are fewer or smaller. That is, the possible candidate values of the Offset are proportional to the period of the SSB.
[0546] The offset between the PEI (i.e., the start or end position of the PEI) and the target SSB can also be fixed, i.e., the offset can be agreed upon by the protocol. For example, the PEI is located in the first slot of the first L frames before the frame where the target PO is located.
[0547] Optionally, the duration of the PEI may be configured or fixed, and the end position (or start position) of the PEI may be determined based on the start position (or end position) of the PEI and the duration of the PEI.
[0548] The distance between the end location of the PEI and the PO must be greater than or equal to the min_gap. For example, the following condition must be met: PO_location - PEI_end ≥ min_gap. The min_gap can be configured by the network or reported by the UE. Alternatively, the distance between the start location of the PEI and the PO must be greater than or equal to the min_gap.
[0549] If the starting position of the PEI or the ending position of the PEI does not meet the above conditions, the starting position of the PEI or the receiving position can be updated to: PEI_location-Period_SSB.
[0550] The terminal starts monitoring the PEI at the start position of the PEI.
[0551] Step 3: The terminal receives or detects PEI at the resource location.
[0552] The steps of the network side device implementing the transmission method of the paging advance indication correspond to those of the user equipment and are not described in detail here.
[0553] Example 4: Taking the determination of the resource location of the PEI through the target PO as an example, in this example, the monitoring start location of the PEI is determined according to the target PO.
[0554] Step 1: Determine the target PO.
[0555] The implementation of step 1 of the fourth embodiment is similar to that of step 1 of the third embodiment, including a PO dense scenario, Ns=4, N=T, such as Figure 8 In the PO sparse scenario, Ns=1, N=T / 4, as shown in Figure 9. The specific implementation process is not described here.
[0556] Step 2: The terminal determines the resource location of the PEI based on the location of the target PO.
[0557] Optionally, the monitoring start position of the PEI may be determined according to the position of the Target PO.
[0558] Among them, the listening start position of the PEI and the Offset of the target PO can be configured. The listening start position of the PEI is determined by the position of the target PO and the Offset. For example, the system frame number (SFN_PEI) where the listening start position of the PEI is located needs to satisfy:
[0559] Y*Period_SSB < SFN_PO - SFN_PEI ≤ (Y + 1)*Period_SSB
[0560] That is, Y*Period_SSB < Offset ≤ (Y + 1)*Period_SSB. Here, SFN_PO is the SFN where the PF corresponding to the Target PO is located.
[0561] Optionally, this Offset can also be negative, that is, the listening start position of the PEI is in front of the SSB.
[0562] The value of the Offset can also be related to the period of the SSB. When the period of the SSB is larger, the possible values of the Offset are more or larger. When the period of the SSB is smaller, the possible values of the Offset are fewer or smaller. That is, the possible candidate values of the Offset are proportional to the period of the SSB.
[0563] The interval Offset between the listening start position of the PEI and the target PO can also be fixed, that is, the interval Offset can be agreed upon by the protocol. For example, the listening start position of the PEI is in the first slot of the first L frames before the frame where the target PO is located.
[0564] Optionally, the search space set of the PEI can be configured. The UE starts to prepare for listening to the PEI from the listening start position of the PEI. The specific listening start position of the PEI is indicated by the "monitoringSlot PeriodicityAndOffset" of the search space set.
[0565] Among them, the listening end position of the PEI can be determined by the listening start position (PEI_location) of the PEI and the duration. For example, PEI_end = PEI_location + duration. At this time, the duration is the duration of multiple search spaces under multiple beams.
[0566] The distance between the listening end position (PEI_end) of the PEI and the PO needs to be greater than or equal to min_gap. For example, it needs to satisfy the following condition: PO_location - (PEI_location + duration) ≥ min_gap. This min_gap can be configured by the network side or reported by the UE.
[0567] If the monitoring end position of PEI does not meet the above conditions, the monitoring start position of PEI can be updated to PEI_location-Period_SSB.
[0568] The terminal starts monitoring the PEI at the monitoring start position of the PEI.
[0569] Step 3: The terminal receives or detects PEI at the resource location.
[0570] The steps of the network side device implementing the transmission method of the paging advance indication correspond to those of the user equipment and are not described in detail here.
[0571] In an embodiment of the present application, the user equipment determines the resource location of the PEI based on one or more of the target SSB, target PO, and target PF, thereby receiving or detecting the PEI for indicating the presence of paging at the resource location, which can reduce the power consumption of the UE. Among them, by determining the resource location of the PEI through the SSB, the PEI can be closer to the SSB, and a greater power saving effect can be obtained at this time. The idle UE can receive the PEI immediately after receiving the SSB. When the PEI indicates that the UE has no paging, the UE can enter a low-power sleep state as soon as possible, thereby reducing power consumption. The embodiment of the present application also provides a method for determining the PEI resource location when one PEI corresponds to multiple POs or multiple PFs.
[0572] Example 5: Taking determining the resource location of the PEI according to the first frame number and the first index as an example.
[0573] The UE and the gNB determine a first frame number and a first index, where the first frame number is a radio frame number where the PEI is located, and the first index is an index of one or more PEIs included in the radio frame corresponding to the first frame number. The UE and the gNB determine a resource location of the PEI based on the first frame number and the first index. The UE receives or detects the PEI sent by the gNB at the resource location.
[0574] The radio frame corresponding to the first frame number includes one or more PEIs, or the starting positions of one or more PEIs. The first index is the index of the PEI in at least one PEI included in the radio frame where the PEI is located, and is used to indicate the position of the PEI in the first frame number.
[0575] Step 1: The UE determines the first frame number, that is, the radio frame number where the PEI is located, which is represented by PEI_SFN. The radio frame number where the PEI is located (that is, the first frame number) satisfies the following formula:
[0576] (PEI_SFN+PF_offset+PEI_offset)mod T
[0577] =(T div N)*floor((UE_ID mod N) / A)*A
[0578] Wherein, PEI_SFN is the frame number of the radio frame in which the PEI is located (i.e., the first frame number); PF_offset is the offset used to determine the PF; PEI_offset is the offset used to determine the PEI_SFN; T is the DRX cycle; N is the total number of PFs in each DRX cycle; Ns is the number of POs contained in each PF; X is the number of POs corresponding to one PEI; UE_ID is 5G-S-TMSI mod 1024. A = max(X / Ns, 1), which means taking the maximum value between X / Ns and 1; or, A = max(floor(X / Ns), 1), which means taking the maximum value between floor(X / Ns) and 1, where floor means rounding down. UE_ID is 5G-S-TMSI mod 1024.
[0579] Among the above parameters, PF_offset, T, N, and Ns can be paging parameters configured by the network device. PEI_offset can be configured by the network device or agreed upon by the protocol and is not limited here. PEI_offset is used to describe the radio frame interval between the PEI frame number (PEI_SFN) and the PO frame number (PF), and its unit is radio frame. X can be configured by the network device or agreed upon by the protocol and is not limited here.
[0580] Step 2: The UE determines the first index. The first index is the index of the PEI in the first frame number, or the index of the PEI in at least one PEI included in the radio frame where the PEI is located, represented by PEI_i_s. For example, when the radio frame corresponding to the first frame number includes one PEI, PEI_i_s = 0; when the radio frame corresponding to the first frame number includes two PEIs, PEI_i_s = 0 or 1.
[0581] Determining the first index may include the following two methods:
[0582] Method 1: The index of PEI in the first frame number satisfies the following formula:
[0583] PEI_i_s=(floor(UE_ID / N)mod Ns)mod B
[0584] Among them, PEI_i_s is the first index, and can also be expressed as the index of one or more PEIs contained in the wireless frame corresponding to the first frame number of PEI; N is the total number of PFs in each DRX cycle; Ns is the number of POs contained in each PF; X is the number of POs corresponding to 1 PEI; B = max(Ns / X, 1) or B = max(floor(Ns / X), 1); UE_ID is 5G-S-TMSI mod 1024. Among the above parameters, T, N, and Ns can be paging parameters configured by the network side device. X can be configured by the network side device, or it can be agreed upon by the protocol, and is not limited here.
[0585] Mode 2: In Mode 2, the first index satisfies the following formula:
[0586] PEI_i_s=i_s mod B
[0587] Wherein, PEI_i_s is the first index, i_s is the i_s corresponding to the PO determined by the user equipment; X is the number of POs corresponding to one PEI. Ns is the number of POs contained in each PF, B = max(Ns / X, 1) or B = max(floor(Ns / X, 1) In this embodiment 5, for the steps 1 and 2, as Figure 9b As shown, take 1 PEI corresponding to 2 PO, X=2 as an example. Figure 9b In the example, the position j indicated by the arrow represents the position of the first index PEI_i_s, which satisfies:
[0588] PEI_i_s=(floor(UE_ID / N)mod Ns)mod B
[0589] Here, B=max(Ns / X, 1) or B=max(floor(Ns / X), 1).
[0590] The position i indicated by the arrow represents the position corresponding to the first frame number PEI_SFN, and the first frame number satisfies:
[0591] (PEI_SFN+PF_offset+PEI_offset)mod T
[0592] =(T div N)*floor((UE_ID mod N) / A)*A
[0593] Where A = max(X / Ns, 1)
[0594] The UE can determine the SFN where the PEI is located through the first frame number determined in step 1 above, and then determine the index of the PEI in at least one PEI included in the radio frame where the PEI is located according to the first index determined in step 2 above. The first index can be used to determine the specific resource location of the PEI in the first frame number. For example, if the first frame number includes two PEIs, then the network-side device configuration "firstPDCCH-MonitoringOccasionOfPEI" includes two values. The resource location of the PEI corresponding to PEI_i_s=0 in the first frame number is determined according to the first value in "firstPDCCH-MonitoringOccasionOfPEI", and the resource location of the PEI corresponding to PEI_i_s=1 in the first frame number is determined according to the second value in "firstPDCCH-MonitoringOccasionOfPEI". The following describes in more detail how to determine the resource location of the PEI according to the first index when the first frame number is determined.
[0595] The UE determines the PDCCH monitoring opportunity of the PEI based on the paging search space, the first PEI's PDCCH monitoring opportunity "firstPDCCH-MonitoringOccasionOfPEI" configured in the "DownlinkConfigCommonSIB" field, and the number of paging PDCCH MOs corresponding to an SSB "nrofPDCCHMonitoringOccasionPerSSB-InPO". When the paging search space is configured with "SearchSpaceId=0", the PEI's PDCCH monitoring opportunity is the same as the remaining minimum system information (RMSI).
[0596] When the "SearchSpaceId" configured in the paging search space configuration is not equal to 0, the UE monitors the (PEI_i_s+1)th PEI. PEI is a set of "S*X" consecutive PDCCH monitoring opportunities, where S is the number of SSBs actually transmitted based on the SSB position information carried by SIB1, and X represents the number of PDCCH MOs corresponding to each SSB configured by "nrofPDCCHMonitoringOccasionPerSSB-InPEI". If this value is not configured, X is equal to 1. When "firstPDCCH-MonitoringOccasionOfPEI" is configured, the starting point of the PDCCH MO for the (PEI_i_s+1)th PEI is the (PEI_i_s+1)th value of the higher-layer parameter "firstPDCCH-MonitoringOccasionOfPEI". Otherwise, the starting point of the PDCCH MO for the (PEI_i_s+1)th PEI is equal to PEI_i_s*S*X.
[0597] According to the above method, the UE and the gNB can determine the resource location of the PEI based on the determined first frame number and the first index. The PEI is the PEI that the UE needs to monitor, and the PEI is used to indicate the paging status of the PO that the UE needs to monitor. The fifth embodiment provides a method for determining the resource location of the PEI based on the first frame number and the first index. This determination method is simpler for the UE and has less impact on the protocol.
[0598] The embodiment of the present application also provides a method for transmitting a paging advance indication, which is applied to a network side device, such as Figure 10 Shown, including:
[0599] Step 101: The network side device determines the resource location of the paging advance indication PEI according to at least one of a target synchronization signal block SSB, a target paging opportunity PO, and a target paging frame PF, or according to a first frame number;
[0600] Step 102: The network side device sends a PEI to the user equipment at the resource location; wherein the PEI is used to indicate the presence of paging.
[0601] In this embodiment, the target SSB is one of the multiple SSBs; the target PO is one of the multiple POs; and the target PF is one of the multiple PFs. When the network-side device determines the resource location of the PEI, it can be determined based on one or a combination of the target SSB, the target PO, and the target PF.
[0602] Optionally, the first frame number is a frame number of a radio frame in which the PEI is located. In an embodiment, the network-side device may determine a resource location of the PEI based on the first frame number. The radio frame corresponding to the first frame number may include one or more PEIs, or the starting position of one or more PEIs.
[0603] After the network-side device determines the resource location of the PEI, it sends the PEI at the resource location. The PEI can be used to indicate the presence of paging, that is, whether paging exists. For example, "1" indicates the presence of paging, and "0" indicates the absence of paging. The UE can receive the PEI at the resource location of the PEI it has determined, and then determine whether it needs to receive a paging message. If it does not need to receive a paging message, it can enter a low-power or sleep state, thereby reducing UE power consumption.
[0604] It should be noted that after the network side device determines the resource location of PEI, it sends PEI at the resource location. The PEI can be used to indicate the presence of paging, that is, the presence or absence of paging is indicated by PEI; or, when there is no paging, the network side device does not send PEI at the determined resource location.
[0605] In an embodiment of the present application, the network side device determines the resource location of the PEI based on one or more of the target SSB, target PO, and target PF, or determines the resource location of the PEI based on the first frame number, thereby sending a PEI for indicating the presence of paging at the resource location, and the UE determines whether it needs to receive the paging message based on the indication of the PEI. Among them, determining the resource location of the PEI through the SSB can make the PEI closer to the SSB, and a greater power saving effect can be achieved at this time. The embodiment of the present application also provides a method for determining the PEI resource location when a PEI corresponds to multiple POs or multiple PFs.
[0606] Optionally, the method further includes: determining at least one of the target SSB, the target PO and the target PF.
[0607] Optionally, determining the target SSB includes: determining the target SSB according to target parameters; wherein the target parameters include: target PO or target PF.
[0608] In this embodiment, the target SSB can be determined according to the target PO or target PF, that is, the resource location of PEI can be determined according to the target PO or target PF, or the target SSB can be determined according to the target PO or target PF, and the resource location of PEI can be determined according to the target SSB.
[0609] Furthermore, determining the target SSB according to the target parameter may include:
[0610] The target SSB is determined according to the position of the target parameter and the distance between the target parameter and the target SSB; wherein the distance satisfies: being greater than the period of Y SSBs and less than or equal to the period of Y+Y1 SSBs, Y being the number of SSBs between the target SSB and the target parameter, and Y1≥1.
[0611] Wherein, the determination method of Y includes at least one of the following:
[0612] System message configuration;
[0613] Broadcast signaling configuration;
[0614] Agreement;
[0615] Determined according to a first interval; the first interval may be the minimum distance between the end position of the PEI and the target PO or target PF, and the first interval may be configured or determined according to other parameters.
[0616] Determined according to the first offset; the first offset can be: the offset between the resource position of the target SSB, or the target PO, or the target PF and the resource position of the PEI.
[0617] It is determined according to the number of beams of the SSB; it should be noted that the SSB may include the target SSB or the non-target SSB, and the number of beams of the target SSB and the non-target SSB is the same.
[0618] Determined according to the number of beams of the PEI.
[0619] In this embodiment, the target SSB can be determined based on the position of the target PO or target PF and the distance between the target PO or target PF and the target SSB. Taking the target PO as an example, the distance satisfies:
[0620] Y*Period_SSB <PO_location–SSB_location≤(Y+1)*Period_SSB
[0621] Period_SSB represents the period of SSB, PO_location represents the location of the target PO (such as the frame number, time slot number or OFDM symbol where the first MO of the target PO starts), and SSB_location represents the location of the target SSB (for example, the frame number, subframe number, time slot number or OFDM symbol where the start or end position of the target SSB is located). PO_location–SSB_location represents the distance. Preferably, Y1=1, and when Y1 is greater than 1, the distance is the maximum distance or minimum distance that meets the above conditions. At this time, the target SSB is the SSB that meets the maximum distance or minimum distance conditions. Y is a function related to the number of SSBs between the target SSB and the target parameter interval.
[0622] As an optional embodiment, a method of determining the target PO or the target PF includes one of the following:
[0623] (1) determining the target PO or target PF according to a first parameter, where the first parameter includes at least one of the total number of PFs in each discontinuous reception (DRX) cycle (i.e., N), the number of POs contained in each PF (i.e., Ns), and a user equipment identifier (i.e., UE_ID);
[0624] (2) determining the target PO or target PF according to a second parameter, where the second parameter is the number of POs corresponding to one PEI;
[0625] (3) determining the target PO or target PF according to the PEI period;
[0626] (4) When one PEI corresponds to one PO, the target PO is the PO corresponding to when the network side device sends the PDCCH scrambled by the paging radio network temporary identifier P-RNTI when paging the user equipment, and the target PF is the PF corresponding to when the network side device sends the PDCCH scrambled by the P-RNIT when paging the user equipment.
[0627] In this embodiment, the network side device determines the target PO or the target PF, and can directly determine the resource location of PEI based on the target PO or the target PF; or, determines the target SSB based on the target PO or the target PF, and determines the resource location of PEI based on the target SSB.
[0628] Optionally, determining the resource location of the PEI according to at least one of the target SSB, the target PO, and the target PF includes:
[0629] The resource location of the PEI is determined based on the resource location of the target SSB, or the target PO, or the target PF, and a first offset; wherein the first offset is the offset between the resource location of the target SSB, or the target PO, or the target PF and the resource location of the PEI.
[0630] The first offset may be configured on the network side or agreed upon by the protocol, i.e., the interval between the fixed PEI and the target SSB, or the interval between the fixed PEI and the target PO, or the interval between the fixed PEI and the target PF. Taking the target SSB as an example, the determination method of the first offset may include:
[0631] 1: The offset between the configured PEI and the target SSB: PEI_location = SSB_location + Offset; where PEI_location is the frame number, subframe number, time slot number or OFDM symbol of the start or end position of PEI; SSB_location is the frame number, subframe number, time slot number or OFDM symbol of the start position of the target SSB.
[0632] It should be noted that the first offset is less than the period length of the target SSB; or, the first offset is proportional to the period of the target SSB.
[0633] 2. The interval between the fixed PEI and the target SSB agreed upon by the protocol, for example, the PEI is located in the next slot of the target SSB.
[0634] Optionally, the resource location of the PEI includes at least one of the following:
[0635] The starting position of the PEI;
[0636] The end position of the PEI;
[0637] The monitoring start position of the PEI;
[0638] The monitoring end position of the PEI.
[0639] Optionally, the method further includes: when the resource location of the PEI includes the start position of the PEI and / or the listening start position of the PEI, determining the end position of the PEI and / or the listening end position of the PEI according to the start position of the PEI and / or the listening start position of the PEI, and the duration of the PEI.
[0640] The end position of PEI can be determined according to the start position and duration of PEI; the end position of PEI monitoring can be determined according to the start position and duration of PEI monitoring.
[0641] It should be noted that, if the end position of the PEI or the end position of the monitoring is determined first, the start position of the PEI or the start position of the monitoring can also be determined according to the duration.
[0642] In an embodiment of the present application, after determining the resource location of the PEI based on one or more of the target SSB, target PO, and target PF, it is further possible to determine whether the determined resource location meets a predetermined condition. If the condition is met, the PEI can be sent at the determined resource location. This is described in detail below.
[0643] Optionally, the method further includes: determining whether the resource location satisfies a first condition; if the first condition is not satisfied, updating the resource location to: the difference between the resource location and the SSB period.
[0644] The first condition may include: a distance between the resource location and the resource location of the target PO or target PF is greater than or equal to a first interval.
[0645] The first interval is the minimum value of the distance between the resource location of the PEI (preferably the end location or the listening end location) and the target PO or target PF. The resource location of the target PO or target PF can be the location of the first MO of the target PO or the starting location of the target PO, or the ending location of the target PO.
[0646] In this embodiment, when determining whether the resource location meets the first condition, the end location or the monitoring end location in the resource location may be judged. For example, the end location meets the condition: PO_location-PEI_end≥min_gap, where min_gap is the first interval.
[0647] When the resource location of the PEI meets the first condition, the step of sending the PEI to the user equipment at the resource location in step 102 can be performed. When the resource location of the PEI does not meet the first condition, the resource location that needs to be updated is: the difference between the resource location (i.e., the resource location determined in step 101) and the SSB period, that is, the resource location is updated to PEI_location-Period_SSB. That is, when the network-side device configures Y according to a system message or broadcast signaling or agrees on a protocol, the UE calculates and updates Y according to min_gap, and the updated Y is Y+1.
[0648] Optionally, the PEI includes X beams, and the resource location of the PEI includes: X resource locations corresponding to the PEI of the X beams; sending the PEI to the user equipment at the resource location may include: when a first resource location among the X resource locations overlaps with the resource location of the first signal, sending the PEI to the user equipment at a second resource location; wherein the second resource location is the first resource location after the first resource location.
[0649] The first resource position is, for example, the Kth resource position among the X resource positions. The first signal may include: at least one of: SSB, CSI-RS, TRS, PDCCH, PDSCH, and DMRS.
[0650] Taking the first signal as an SSB or TRS signal as an example, when the Kth resource position among multiple resource positions completely or partially overlaps with the resource position where the SSB, TRS and other signals are located, the Kth resource position is an invalid PEI resource position, and the K+1th resource position is used to transmit the PEI of the Kth beam, that is, the invalid PEI resource position can be discarded or skipped, and the valid PEI resource position is postponed.
[0651] As an optional embodiment, for the method of determining the resource location of the PEI according to the first frame number, the method further includes:
[0652] The first frame number is determined, where the first frame number is the frame number of the radio frame where the PEI is located. The network side device determines the first frame number, that is, determines the frame number of the radio frame where the PEI is located. The first frame number can be represented by PEI_SFN.
[0653] Optionally, the method further comprises: determining a first index, the first index being an index of the PEI;
[0654] Determining the resource location of the paging advance indication PEI according to the first frame number may include: determining the resource location of the PEI according to the first frame number and the first index.
[0655] In this embodiment, the first index is an index of the PEI, which may be an index of the PEI in at least one PEI included in the radio frame where the PEI is located. The first index may be represented by PEI_i_s. For example, when the radio frame corresponding to the first frame number includes one PEI, PEI_i_s=0; when the radio frame corresponding to the first frame number includes two PEIs, PEI_i_s=0 or 1.
[0656] In an embodiment of the present application, determining, by the network-side device, the resource location of the PEI based on the first frame number may include: determining the resource location of the PEI based solely on the first frame number; or determining the resource location of the PEI based on the first frame number and a first index. For example, when the radio frame corresponding to the first frame number includes only one PEI, the resource location of the PEI may be determined based solely on the first frame number; when the radio frame corresponding to the first frame number includes multiple PEIs, the resource location of the PEI may be determined using both the first frame number and the first index.
[0657] Optionally, determining the first frame number includes: determining the first frame number based on a third parameter, the third parameter including: the second interval (PEI_offset), the offset of the paging frame (PF_offset), the DRX cycle (T), the total number of PFs in each DRX cycle (N), the number of POs contained in each PF (Ns), the number of POs corresponding to a PEI (X), and at least one of the user equipment identifier (UE_ID).
[0658] The second interval is used to determine the first frame number, and the second interval can be used to describe the radio frame interval between the first frame number and the frame number where the PO is located (i.e., PF). The paging frame offset is used to determine the PF offset. The first frame number can be determined based on one or more of the third parameters.
[0659] Optionally, the first frame number is related to the product of a fourth parameter, a fifth parameter, and a sixth parameter. The fourth parameter is related to at least one of the DRX cycle and the total number of PFs within each DRX cycle. Optionally, if the fourth parameter is related to the DRX cycle (T) and the total number of PFs within each DRX cycle (N), the fourth parameter may satisfy (T div N).
[0660] The fifth parameter is related to at least one of the user equipment identifier, the total number of PFs in each DRX cycle, and the sixth parameter.
[0661] The sixth parameter is related to at least one of the number of POs corresponding to a PEI and the number of POs contained in each PF.
[0662] Optionally, if the sixth parameter is related to the number of POs corresponding to a PEI (X) and the number of POs contained in each PF (Ns), the sixth parameter (A) may satisfy: A = max(X / Ns, 1), that is, taking the maximum value between X / Ns and 1; or, the sixth parameter (A) may satisfy: A = max(floor(X / Ns), 1), that is, taking the maximum value between floor(X / Ns) and 1, where floor means rounding down.
[0663] If the fifth parameter is related to the user equipment identifier (UE_ID), the total number of PFs in each DRX cycle (N), and the sixth parameter (A), the fifth parameter may satisfy: floor((UE_ID mod N) / A).
[0664] Specifically, a modulo operation result of the sum of the first frame number, the second interval, and the offset of the paging frame, and the DRX cycle is equal to the product of the fourth parameter, the fifth parameter, and the sixth parameter.
[0665] Taking the fourth parameter satisfying (T div N), the fifth parameter satisfying floor((UE_ID mod N) / A), and the sixth parameter satisfying A=max(X / Ns, 1) or A=max(floor(X / Ns), 1) as an example, the first frame number satisfies the following formula:
[0666] (PEI_SFN+PF_offset+PEI_offset)mod T
[0667] =(T div N)*floor((UE_ID mod N) / A)*A
[0668] Among them, PEI_SFN is the frame number of the wireless frame where PEI is located (i.e., the first frame number); PF_offset is the offset used to determine PF; PEI_offset is the offset used to determine PEI_SFN; T is the DRX cycle; N is the total number of PFs in each DRX cycle; Ns is the number of POs contained in each PF; X is the number of POs corresponding to 1 PEI; UE_ID is 5G-S-TMSImod 1024.
[0669] It should be noted that PF_offset, T, N, and Ns may be paging parameters configured by the network device. PEI_SFN may be configured by the network device or agreed upon by the protocol, and this embodiment does not limit this. PEI_offset is used to describe the radio frame interval between the PEI frame number (PEI_SFN) and the PO frame number (PF), and its unit is radio frames. X may be configured by the network device or agreed upon by the protocol, and this embodiment does not limit this.
[0670] As an optional embodiment, determining the first index may include:
[0671] Method (a): Determine the first index according to a seventh parameter, where the seventh parameter includes at least one of: a user equipment identifier (UE_ID), a total number of PFs in each DRX cycle (N), a number of POs contained in each PF (Ns), and a number of POs corresponding to a PEI (X);
[0672] or
[0673] Method (b): Determine the first index based on the PO index (i_s), the number of POs contained in each PF (Ns), and the number of POs corresponding to a PEI (X). The PO index may be the index of the PO received or detected by the user equipment.
[0674] In this embodiment, the network side device determines a first index, that is, an index of the PEI in the first frame number, or an index of the PEI in at least one PEI included in the radio frame where the PEI is located. The first index can be represented by PEI_i_s. For the above method (a), if the seventh parameter includes: a user equipment identifier (UE_ID), a total number of PFs in each DRX cycle (N), a number of POs contained in each PF (Ns), and a number of POs corresponding to a PEI (X), then the first index can satisfy:
[0675] PEI_i_s=(floor(UE_ID / N)mod Ns)mod B
[0676] Among them, PEI_i_s is the first index, which can also be expressed as the index of one or more PEIs contained in the wireless frame corresponding to the first frame number of PEI; N is the total number of PFs in each DRX cycle; Ns is the number of POs contained in each PF; X is the number of POs corresponding to 1 PEI; B = max(Ns / X, 1) or B = max(floor(Ns / X), 1); UE_ID is 5G-S-TMSI mod 1024.
[0677] T, N, and Ns may be paging parameters configured by the network side device. X may be configured by the network side device or may be a protocol agreement, which is not limited in this embodiment.
[0678] For the method (b), that is, the first index can be determined based on the index of the PO (i_s), the number of POs contained in each PF, and the number of POs corresponding to a PEI (X), then the first index can satisfy:
[0679] PEI_i_s=i_s mod B
[0680] Where PEI_i_s is the first index, i_s is the i_s corresponding to the PO determined by the user equipment; X is the number of POs corresponding to one PEI. Ns is the number of POs contained in each PF, B = max(Ns / X, 1) or B = max(floor(Ns / X, 1)
[0681] In this embodiment, when the network side device determines the resource location of PEI, it can be determined based on the first frame number, wherein it can be determined based only on the first frame number, or it can be determined based on the first frame number and the first index. For the network side device, this determination method is simple and has less impact on the protocol.
[0682] It should be noted that the implementation method of the user equipment determining the resource location of the PEI according to at least one of the target SSB, target PO and target PF, or according to the first frame number is applicable to the method embodiment of the network side device, such as Figure 2-9b As shown, no further details are given here.
