Description

[0001] This application is a divisional application of a patent application for invention, with international application number PCT / CN2022 / 071235, international filing date January 11, 2022, entering the Chinese national phase on February 28, 2024, Chinese national application number 202280058971.4, and invention title "Method, apparatus, and system for determining the location of a paging early indication". Technical Field

[0002] The present disclosure generally relates to wireless communication. In particular, the present disclosure relates to a method, apparatus, and system for determining the location of a paging early indication (PEI). Background Art

[0003] Wireless communication technologies are driving the world towards an increasingly interconnected and networked society. High-speed and low-latency wireless communication relies on efficient network resource management and allocation between one or more user equipments and one or more radio access network nodes (including but not limited to base stations). The new generation of networks is expected to provide high-speed, low-latency, and ultra-reliable communication capabilities and meet the requirements of different industries and users.

[0004] With the rapid development of cellular mobile communication systems, for example, in current radio access protocols, a user equipment (UE) may need to monitor a paging occasion (PO) in each paging cycle or paging time window (PTW) so that the UE can obtain a paging message according to the paging occasion. However, in most cases, the UE may not have a paging message in all paging cycles, so actively monitoring the paging occasion may result in unnecessary power consumption. This problem may be severe for some UEs with a relatively low paging probability, and these UEs may detect a large number of unnecessary paging occasions, resulting in unnecessarily high power consumption. A paging early indication (PEI) with indication information before the PO can be used to indicate whether the UE needs to receive a paging physical downlink control channel (PDCCH). This solution can reduce the power consumption caused by excessive paging reception. One of the problems may be how the UE accurately locates the PEI and reduces the power consumption caused by blind detection.

[0005] The present disclosure describes various embodiments for determining the location of a paging early indication (PEI), which solve at least one of the above problems. Various embodiments in the present disclosure can reduce and / or save power consumption, improve the efficiency of monitoring paging occasions, and / or improve the accuracy of receiving paging messages, thereby improving the user experience and / or the technical field in wireless communication.

[0023] This disclosure describes various methods and apparatuses for determining the location of a paging early indication (PEI).

[0024] With the rapid development of cellular mobile communication systems, for example, in current radio access protocols, a user equipment (UE) may need to monitor a paging occasion (PO) in each paging cycle (e.g., each discontinuous reception (DRX) cycle) so that the UE can obtain a paging message according to the paging occasion. However, in most cases, the UE may not have a paging message in all paging cycles, and thus actively monitoring the paging occasion may result in unnecessary power consumption. This problem may be severe for some UEs with a relatively low paging probability, whereby a large number of unnecessary paging messages may be received, resulting in unnecessary high power consumption.

[0025] In some implementations, a paging early indication (PEI) having indication information before a PO may indicate whether the UE needs to receive a paging physical downlink control channel (PDCCH) in the PO. This may reduce the power consumption caused by paging reception. In some implementations, different PEI locations may bring different power saving effects.

[0026] In some implementations, one PEI may indicate multiple POs in different PFIs. One of the problems may include how to enable UEs corresponding to different POs to find the same PEI. In some other implementations, different PEI locations may bring different power saving gains. Therefore, in order to allow the UE to accurately locate the PE and reduce the power consumption caused by blind detection, one of the problems may include how the UE locates the PEI.

[0027] The present disclosure describes various embodiments for determining the location of a Paging Early Indication (PEI), which solves at least one of the above-mentioned dilemmas / problems. Various embodiments in the present disclosure can reduce and / or save power consumption, improve the efficiency of monitoring paging occasions, and / or improve the accuracy of receiving paging messages, thereby improving the user experience and / or the technical field in wireless communications.

[0028] In various embodiments, a UE may monitor one paging occasion (PO) for each discontinuous reception (DRX) cycle (i.e., paging cycle). A paging frame (PF) is a radio frame (RF) and may contain one or more POs or the starting points of POs. The PF and PO for paging can be determined by the following formulas. The system frame number (SFN) of the PF is determined by (SFN + PF_offset) mod T = (T div N) * (UE_ID mod N), and the index (i_s) indicating the index of the PO is determined by i_s = floor(UE_ID / N) mod Ns, where T represents the DRX cycle of the UE; N represents the total number of paging frames in T; Ns represents the number of paging occasions of the PF; PF_offset represents the offset used for PF determination; UE_ID represents the fifth-generation (5G) system temporary mobile subscription identifier (5G-S-TMSI) mod 1024.

[0029] In some other embodiments, the value of N * Ns can determine the number of POs in the DRX cycle, i.e., the density of POs in the DRX cycle, where N is the total number of paging frames in the DRX cycle; and Ns is the number of paging occasions of the PF.

[0030] In some other embodiments, the location of the PEI can be determined by a frame-level offset and a symbol-level offset. The frame-level offset can be the frame-level offset from the start of the first PF among at least one paging frame (PF) associated with the Paging Early Indication occasion (PEI-O) to a reference point. The symbol-level offset can be the symbol-level offset from the reference point to the start of the first Physical Downlink Control Channel (PDCCH) monitoring occasion of the PEI-O.

Each of the UEs may communicate wirelessly with the wireless network node via one or more radio channels 115. For example, the first UE 110 may communicate wirelessly with the wireless network node 118 via a channel including multiple radio channels during a specific time period. The network base station 118 may send high-layer signaling to the UE 110. The high-layer signaling may include configuration information for communication between the UE and the base station. In one implementation, the high-layer signaling may include radio resource control (RRC) messages.

[0040] In some implementations, the UE may monitor a paging indication (PEI) in a paging early indication occasion (PEI-O). In some other implementations, the PEI may be carried on downlink control information (DCI), such as DCI format 2_7. The PEI-O position may be determined by a reference point and a symbol-level offset from the reference point to the start of a first PDCCH monitoring occasion (MO) of the PEI-O. The reference point may be the start of a reference frame determined by a frame-level offset from the start of a first paging frame (PF) among the (one or more) paging frames (PFs) associated with the PEI-O.

[0041] In various embodiments, the determination of the first PF is based on the following: the PF in which the UE monitors a paging occasion (PO), the system frame number (SFN) of the PF of the UE (denoted as SFN_PO), the index of the PO in at least one PO associated with the PEI (denoted as i PO) The paging cycle (denoted as T), the total number of paging frames in the paging cycle (denoted as N), the number of POs in the PF (denoted as N S ) The index of the PO in one or more POs in the PF (denoted as i_s), the UE identifier (UE_ID), the number of POs associated with the PEI (denoted as ) Or an offset used to determine the PF (denoted as PF_offset).

[0046] In some other implementations, the first PF is determined by the SFN of the first PF according to the following formula: Where SFN_firstPF is the SFN of the first PF, floor(x) is the floor function that outputs the largest integer less than or equal to x, and mod() is the modulo operation that outputs the remainder of a division.

[0047] In various embodiments, the first PF can be determined by at least one of the following: the PF in which the UE monitors the PO; SFN_PO: the system frame number (SFN) of the PF of the UE, and in some implementations, the PF of the UE determined by the SFN for the PF is determined by (SFN + PF_offset) mod T = (T div N) * (UE_ID mod N); i_PO: the index of the PO among the POs associated with the PEI; T: the paging cycle; N: the total number of paging frames in the paging cycle; Ns: the number of paging occasions of the PF; i_s: the index of the PO among the POs in a PF; UE_ID; The number of POs associated with the PEI; and / or PF_offset: the offset for PF determination. In some implementations, the PO associated with the PEI represents the PO corresponding to the PEI. In some other implementations, the PO associated with the PEI indicates whether one or more UEs monitor the PO as indicated by the PEI.

When the value of i_PO is less than or equal to Ns, the first PF is the PF of the UE; and / or when the value of i_PO is greater than Ns, the first PF is the previous PF before the PF of the UE. The distance between the previous PF and the PF of the UE can be T / N radio frames (RF). The SFN of the previous PF can be equal to the SFN of the PF of the UE minus T / N. In certain implementations, the distance between the previous PF and the PF of the UE is the distance between the start of the previous PF and the start of the PF of the UE. In some other implementations, the distance between the previous PF and the PF of the UE is the distance between the time slots of the previous PF and the time slots of the PF of the UE with the same number of time slots.

[0075] In some other implementations, the SFN value of the PEI is not greater than the SFN value of the first SFN or the SFN value of the paging frame monitored by the UE.

[0076] In some other implementations, the frame-level offset corresponding to the (i_s + 1)-th PO can be the th value in the frame-level offset list.

[0079] In some other implementations, the minimum value of the frame-level offset can be zero.

[0080] In some other implementations, when the value of the frame-level offset can be equal to 0, the PEI can be located before the paging PDCCH monitoring occasion in the frame. That is, the symbol-level offset of the PEI can be less than the value of firstPDCCH - MonitoringOccasionOfPO. The parameter firstPDCCH - MonitoringOcsionOfPO can be used to determine the first PDCCH monitoring occasion of the paging PDCCH.

[0083] In some other implementations, the frame-level offset is a value. The value of the frame-level offset is determined by the period of the SSB. For example, the value is greater than or equal to N times the SSB transmission period, where N is a positive integer. For example, N = 1, N = 2, N = 3, N = 5.

[0084] In some other implementations, the frame-level offset is a range containing multiple values, and the maximum value of the frame-level offset satisfies the following condition: the maximum value of the frame-level offset is greater than or equal to N times the SSB period, where N is a positive integer. For example, N = 1, N = 2, N = 3 and / or N = 5. In some other implementations, the range of the frame-level offset is {0, 1, 2, …, N * SSB periods}.

[0085] In some other implementations, the frame-level offset is a value. The value of the frame-level offset is determined by the UE type. For example, for a non-reduced-capability (non-RedCap) UE, the value of the frame-level offset is 6, and for a reduced-capability (RedCap) UE, the value of the frame-level offset is 10 ms.

[0086] In some other implementations, the frame-level offset is a range containing multiple values, and the range or maximum value of the frame-level offset is determined by the UE type or DRX type. For example, for a non-RedCap UE, the maximum value of the frame-level offset is 6, while for RedCap, the maximum value of the frame-level offset is 10, and the unit of the frame-level offset is radio frames, i.e., 10 ms. In some other implementations, the range of the frame-level offset is {0, 1, 2,..., X}, and X is determined by the UE type or DRX type.

For example, for a non-RedCap UE, N is equal to 2, and for a RedCap UE, N is equal to 5. That is, the value of the frame-level offset is greater than or equal to 4 for a non-RedCap UE, and the value of the frame-level offset is greater than or equal to 10 for a RedCap UE.

[0092] In some other implementations, the maximum value of the frame-level offset is greater than or equal to N times the period of the SSB, where N is a positive integer and the value of N is different for different UE types or DRX types. For example, for a non-RedCap UE, N is equal to 3, and for a RedCap UE, N is equal to 5. For a non-RedCap UE, the maximum value of the frame-level offset is greater than or equal to 6, and for a RedCap UE, the value of the frame-level offset is greater than or equal to 10. The unit of the frame-level offset is frames, i.e., 10 ms. In some other implementations, the frame-level offset range is {0, 1, 2,..., N * SSB periods}, and N is determined by the UE type or DRX type.

[0093] In some other implementations, the range or maximum value of the frame-level offset is determined by the paging cycle or the type of DRX cycle. In some embodiments, for a UE configured with an e-DRX (extended DRX) cycle, the range or maximum value of the frame-level offset is greater than that of a UE with a normal DRX or paging cycle configuration. For example, for a UE with a normal DRX or paging cycle, the range of the frame-level offset is 0 - 6, while for a UE with an e-DRX configuration, the range of the frame-level offset is 0 - 20.

[0094] In some other implementations, the maximum value of the frame-level offset of a UE with an e-DRX configuration is m times that of a UE with a normal DRX configuration. m can be a positive integer.

In some other implementations, n can be one of 0, 1, 2, 3, 4, 5, or 6; thus, m can be one of 1, 2, 4, 8, 16, 32, or 64.

[0104] In various embodiments, a symbol-level offset list is a list that includes one or more symbol-level offsets, and the number of candidate values of the symbol-level offset list can be determined by at least one of the following: the number of PEIs in a frame. For example, the number of PEIs in a frame indicates that the PEIs correspond to the same reference frame, or the PEIs in a frame indicate that the PEIs correspond to the same reference point; the number of POs associated with a PEI and / or the number of POs of a PF (Ns).

[0105] In some implementations, the number of candidate values of the symbol-level offset list can be equal to the number of PEIs in a frame, or equal to the number of PEIs corresponding to a reference point.

[0106] In some other implementations, the number of candidate values of the symbol-level offset list can be equal to That is, when the number of POs associated with a PEI is greater than the number of POs in a PF, one symbol-level offset value is sufficient. When the number of POs associated with a PEI is less than the number of POs in a PF, the symbol-level offset will include values.

For example, the symbol-level offset can be determined as follows: when the SCS is 15KHz, the range of symbol-level offset can be 0 - 139 symbols; when the SCS is 30KHz, the range of symbol-level offset can be 0 - 279 symbols; when the SCS is 60KHz, the range of symbol-level offset can be 0 - 559 symbols; and / or when the SCS is 120KHz, the range of symbol-level offset can be 0 - 1119 symbols.

[0114] In some other implementations, the reference point is the starting point of the reference frame, so the position of the reference point can be accurate to the radio frame level. Based on the reference point, the symbol-level offset further locates the PEI to the symbol level, and the first monitoring occasion of the PEI can be any symbol within the reference frame.

For example, the ratio of the demodulation reference signal (DMRS) energy (EPRE) per resource element of the PEI to the SSS EPRE is between -X dB and X dB. For example, X = 8. Here, in various embodiments of the present disclosure, dB may refer to decibel, and is equal to one tenth of bel (B), which represents the ratio of two values of power or root power quantity on a logarithmic scale.

[0124] In some other implementations, if the PEI is configured, the transmission power of the PEI can be configured by a higher layer parameter. Otherwise, the ratio of the DMRS EPRE of the PEI to the SSS EPRE is between -X dB and X dB. For example, X = 8.

[0125] In some other implementations, the DMRS EPRE of the PEI can be equal to the DMRS EPRE of the paging PDCCH. In some other embodiments, the ratio of the DMRS EPRE of the PEI to the DMRS EPRE of the paging PDCCH is between -X dB and X dB. For example, X = 3.
