A paging method, a terminal and a network side device

[0001] Cross-reference to Related Applications

[0002] This application claims priority to the Chinese patent application No. 2024113863648, filed on September 29, 2024, and entitled "A paging method, a terminal and a network side device", the content of which is incorporated herein by reference in its entirety. TECHNICAL FIELD

[0003] The present application relates to the field of communication technology, in particular to a paging method, a terminal and a network side device. BACKGROUND

[0004] In wireless communication, when the network side receives a request for paging a terminal, according to the terminal location information, the terminal is sent at a suitable time according to the terminal listening rule for paging messages. The wireless frame and subframe used for the terminal to monitor the paging message are paging frame (PF) and paging occasion (PO) respectively.

[0005] In the related art, the PF is determined based on the offset value of the paging frame time point; the terminal device is in discontinuous reception (DRX), and needs to select 1 or 2 SSBs closest to the PO for pre-synchronization, which is used for receiving gain and time-frequency offset adjustment, and then receiving the paging message.

[0006] However, in Non-Terrestrial Network (NTN) communication, the cell range is expanded, the maximum is divided into 1013 wave positions, the SSB and the wave position are bound, 1 synchronization signal block index (SSB index) can correspond to multiple wave positions. The SSB index is expanded to a maximum of 256, and the SSB search period is expanded to a maximum of 640ms. In the DRX scenario, the SSB and the paging occasion may have a large interval in the time domain, and the pre-synchronization result is difficult to use in paging reception, and will cause the terminal to wake up too early.

[0104] In order to make the purpose, technical solutions and advantages of the present application more clear, the following will combine the drawings to further describe the present application in detail. Obviously, the described embodiments are only some embodiments of the present application, but not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative labor are within the protection scope of the present application.

[0105] The terms "first", "second", "third", etc. are used only for descriptive purposes and do not connote or imply relative importance or a quantity of the indicated technical features. Thus, features defined with "first", "second" can explicitly or implicitly include one or more of the features. In the description of the present application, the meaning of "a plurality of" is two or more, unless otherwise specified.

[0106] In the description of the present application, it should be noted that unless otherwise explicitly specified and limited, the term "connection" should be understood broadly, for example, it can be direct connection or indirect connection through an intermediate medium, and it can be internal connection of two devices. For those skilled in the art, the specific meaning of the above-mentioned term in the present application can be understood according to the specific circumstances.

[0107] When the network side receives the request of paging the terminal, according to the terminal location information, the terminal is sent at the appropriate time according to the terminal monitoring paging message rule. The radio frame and subframe for the terminal to monitor the paging message are PF and PO respectively, and the monitoring occasion needs to be determined in PO.

[0108] For example, the system frame number (SFN) of the paging frame is determined by (SFN+PF offset )mod T=(T div N)*(UE_ID mod N);

[0109] The index i of the paging occasion is determined by i s =floor(UE_ID / N)mod Ns;

[0110] Wherein, T is the paging cycle configured by the network side, N is the number of paging frames in T, PF offset is the offset value of the paging frame time point, UE_ID=5G-S-TMSI mod 1024 (5G-S-TMSI is a temporary terminal identifier provided by the network side), and Ns is the number of paging occasions in one paging frame.

[0111] Referring to FIG. 1, there are N PFs in the paging cycle T, each PF has Ns POs, each PO contains S PDCCH monitoring occasions, the PDCCH monitoring occasion corresponds to an SSB, and S is the actual number of SSBs transmitted in one SSB cycle, which is indicated by the parameter ssb-PositionInBurst of the system message block. The terminal receives and monitors paging according to the currently selected SSB index. Referring to FIG. 1, the terminal selects the PDCCH occasion corresponding to SSB index Y+1 to monitor paging.

[0112] Referring to FIG. 2, the paging cycle configured by the operator is generally 2.56s or 5.12s, and the terminal device is in DRX, enters sleep between two pages to save power consumption. After waking up, due to the influence of wireless environment and temperature drift, the terminal needs to select 1 or 2 SSBs closest to PO for presynchronization, for receiving gain and time-frequency offset adjustment, and then receiving the paging message.

[0113] However, in NTN, the cell range is expanded, the maximum is divided into 1013 wave positions, SSB and wave position are bound, 1 SSB index can correspond to multiple wave positions. The SSB index is expanded to a maximum of 256, and the SSB search period is expanded to a maximum of 640ms. Due to the expansion of SSB index, the corresponding wave position is sent in each time slot, and at the same time, the base station needs to send SSB, public message, etc. according to the predetermined wave position pattern, resulting in high complexity of base station scanning pattern; since there is no binding relationship between SSB and paging in time domain, the maximum time delay change caused by satellite movement is 30.46us, and the maximum Doppler shift is 0.17ppm, during the interval of 640ms, the presynchronization result based on SSB cannot be used for paging reception; due to the interval between SSB and paging, the terminal sleep time will be shortened and the power consumption will be increased when the terminal is awakened in the above-mentioned manner. Taking the reception of 2 SSBs as an example, the terminal needs to wake up 1.28s in advance.

[0114] In view of this, the embodiments of the present application propose a paging method, a terminal and a network side device for paging in NTN scenario.

[0115] The technical solutions of the present application and how the technical solutions of the present application solve the above technical problems will be described in detail below in combination with the drawings and specific embodiments. The following specific embodiments can be combined with each other, and the same or similar concepts or processes can not be described in detail in some embodiments.

[0116] FIG. 3 is an interaction flowchart of a paging method provided by an embodiment of the present application, as shown in FIG. 3, comprising the following steps:

[0117] Step S301: The network side device and the terminal determine the time slot information corresponding to the terminal based on the SSB index corresponding to the terminal and a preset parameter for a paging occasion in a paging frame corresponding to the terminal.

[0118] The paging frame is associated with a first SSB period; and the preset parameter is associated with a second SSB period.

[0119] For the NTN scenario, due to the SSB index expansion, the cell range expansion, the maximum division into 1013 waves, the SSB and wave binding, one SSB index can correspond to multiple waves. The SSB index is expanded to a maximum of 256, the first SSB period, that is, the time length occupied by all SSB indexes (256), is expanded to a maximum of 640 ms, and the paging frame needs to accommodate all SSBs (256) in a period; therefore, the above-mentioned embodiment does not apply to the NTN scenario, and the terminal corresponding paging frame needs to be associated with the first SSB period.

[0120] In this embodiment, there is one paging occasion in each paging frame, that is, Ns=1.

[0121] For one paging occasion, there are multiple system frames and multiple time slots, and the terminal corresponding time slot information and paging system frame also need to be determined.

[0122] In this embodiment, according to the characteristics of SSB and wave binding, SSB period expansion, and base station beam scanning, the time division multiplexing relationship between SSB and paging occasion is established.

[0123] In the implementation, by setting a preset parameter based on the second SSB period (SSB search period), and based on the preset parameter, the time slot information and the paging system frame are constrained, the SSB index is combined with the paging, so as to associate the SSB and the time slot information and the paging system frame in the time domain, and the influence of the SSB index and the period expansion in the NTN scenario is reduced.

[0124] The above-mentioned second SSB period is the time length occupied by a group of SSB indexes (8).

[0125] The SSB index corresponding to the terminal is related to the paging area, and the terminal corresponding SSB index has SSB2, SSB3, SSB6, SSB7, and SSB8, as shown in FIG. 4, wherein SSB2, SSB3, SSB6, and SSB7 are a group, and SSB8 is in the next group.

[0126] Step S302: The network side device and the terminal determine the paging system frame based on the SSB index, the preset parameter, and the SSB system frame.

[0127] The order of the above-mentioned steps S301 and S302 is not limited in this embodiment.

[0128] Step S303: The network side device performs paging transmission based on the paging system frame and the time slot information.

[0129] Since the SSB and time slot information and the paging system frame are associated in the time domain in the embodiment, the network side device can perform paging according to a consistent beam scanning pattern, and beam scanning is simplified without reducing paging capacity.

[0130] Step S304: The terminal performs paging monitoring based on the paging system frame and the time slot information.

[0131] Since the SSB and time slot information and the paging system frame are associated in the time domain in the embodiment, the SSB and the paging occasion are less than one second SSB period (20 ms) in the time domain, and the terminal can use the terrestrial terminal paging reception method in the DRX scenario, pre-synchronize based on the SSB, and effectively reduce power consumption.

[0132] The above scheme determines the paging frame corresponding to the terminal according to the first SSB period, so that the paging frame can accommodate all SSBs in one first SSB period in the NTN scenario; the SSB index and paging are combined by setting the preset parameter based on the second SSB period and constraining the time slot information and the paging system frame based on the preset parameter, so that the SSB and time slot information and the paging system frame are associated in the time domain, the influence of SSB index and period expansion in the NTN scenario is reduced; the network side device can perform paging according to a consistent beam scanning pattern, and beam scanning is simplified without reducing paging capacity; the SSB and the paging occasion are less than one second SSB period (20 ms) in the time domain, and the terminal can use the terrestrial terminal paging reception method in the DRX, pre-synchronize based on the SSB, and effectively reduce power consumption. That is, in the NTN scenario, the embodiment guarantees that the paging frame can accommodate all SSBs in one period in the NTN scenario, simplifies beam scanning without reducing paging capacity, effectively pre-synchronizes based on the SSB in the DRX, and effectively reduces power consumption.

[0133] In some optional embodiments, the first SSB period contains a plurality of the second SSB periods.

[0134] For example, the first SSB period is the time length occupied by all SSB indexes, the second SSB period is the time length occupied by a group of SSB indexes, and all SSBs are divided into a plurality of groups, so that the first SSB period can contain a plurality of second SSB periods.

[0135] In some optional embodiments, before the above step S301, the network side device can further perform the following steps:

[0136] The first SSB period and the preset parameter are sent to the terminal; or

[0137] send the first SSB period and the second SSB period to the terminal, so that the terminal determines the preset parameter based on the second SSB period; or

[0138] send the first SSB period to the terminal, so that the terminal determines the second SSB period based on the first SSB period and a preset multiple, and determines the preset parameter based on the second SSB period.

[0139] In an implementation, the terminal needs to determine the time slot information and the paging system frame based on the preset parameter, and therefore, the terminal needs to know the preset parameter in advance. In addition, the corresponding paging frame also needs to be determined based on the first SSB period.

[0140] For example, the network-side device directly sends the first SSB period and the preset parameter to the terminal, so that the terminal can know the first SSB period and the preset parameter.

[0141] Since the preset parameter is associated with the second SSB period, the association between the preset parameter and the second SSB period can be configured in some terminals, or the network-side device sends the association between the preset parameter and the second SSB period in advance. The network-side device sends the first SSB period and the second SSB period to the terminal, and the terminal can also determine the preset parameter based on the association between the second SSB period and the preset parameter.

[0142] Since the first SSB period and the second SSB period have a multiple relationship, the association between the preset parameter and the second SSB period can be configured in some terminals, or the network-side device sends the association between the preset parameter and the second SSB period in advance. In addition, the multiple relationship (preset multiple) between the second SSB period and the first SSB period can also be configured, or the network-side device sends the multiple relationship between the second SSB period and the first SSB period in advance. Therefore, the network-side device sends the first SSB period to the terminal, and the terminal can also determine the second SSB period based on the multiple relationship between the second SSB period and the first SSB period, and then determine the preset parameter based on the association between the second SSB period and the preset parameter.

[0143] The above scheme enables the terminal to know the first SSB period and the preset parameter in multiple ways, and meets the interaction requirements of the network-side device and the terminal in different scenarios.

[0144] In some optional implementations, the paging frame can be determined in the following ways, but is not limited to the following ways:

[0145] determine the number of paging frames in the preset paging period based on the first SSB period and the preset paging period;

[0146] determine the paging frame based on the first SSB period, the identification information of the terminal, the number of paging frames, and the preset paging period.

[0147] For example, SFN mod T = Pmax_ssb * (UE_ID mod N).

[0148] N = T div Pmax_ssb.

[0149] wherein T is a preset paging period (a paging period configured by the network side), N is the number of paging frames in T, Pmax_ssb is the first SSB period (640 ms), and UE_ID = 5G-S-TMSI mod 1024 (5G-S-TMSI is a temporary terminal identifier provided by the network side).

[0150] In some optional embodiments, the preset parameters include a monitoring window parameter, a first preset interval, and a second preset interval; and the step S301 can be implemented by, but is not limited to, the following manners:

[0151] determining a first SIB1 time slot based on the SSB index and the monitoring window parameter; adding the first preset interval to the first SIB1 time slot to determine a first paging time slot;

[0152] adding the second preset interval to the first SIB1 time slot to determine a second SIB1 time slot; and adding the second preset interval to the first paging time slot to determine a second paging time slot;

[0153] wherein the first SIB1 time slot and the second SIB1 time slot are time slots in which the network side device transmits SIB1 through PDCCH, that is, time slots in which the terminal monitors PDCCH for SIB1;

[0154] the first paging time slot and the second paging time slot are time slots in which the network side device pages through PDCCH, that is, time slots in which the terminal monitors PDCCH for paging.

[0155] In this embodiment, the SSB index and paging are time-division multiplexed.

[0156] For example, the monitoring window parameter includes a parameter M (the parameter M controls the overlapping degree of Type0 PDCCH-CSS monitoring windows corresponding to SSB_i and SSB_i+1) and a parameter O (the parameter O is used to control the position of the Type0 PDCCH-CSS monitoring window corresponding to the first SSB). The specific values of the parameters M and O are related to the second SSB period. For example, in 5G communication, the second SSB period is 20 ms, the parameter M can be set to 4, and the parameter O can be set to 2.

[0157] determining a time slot n0 corresponding to SIB1 (first SIB1 time slot), wherein u is a subcarrier spacing, and i is an SSB index, is a number of time slots contained in each system frame for a subcarrier spacing u.

[0159] determining a time slot n p corresponding to paging, n0+Y (first paging time slot), n0+X+Y (second paging time slot), Y being a first preset interval.

[0160] The first preset interval and the second preset interval are limited by a second SSB period, and need to ensure that all SIB1 time slots and paging time slots are contained in the second SSB period,

[0164] determining, based on the time slot arrangement information, that a paging system frame corresponding to each time slot information is the system frame where the SSB is located or a next system frame of the system frame where the SSB is located.

[0166] Exemplarily, the time slot arrangement information

[0167] If the time slot arrangement information is 1, it represents that time slots are arranged full in the system frame where the SSB is located, and a paging system frame SFN PO is SFN SSB_ i+1, that is, the paging system frame is the next system frame of the system frame where the SSB is located;

[0168] If the time slot arrangement information is 0, it represents that time slots are not arranged full in the system frame where the SSB is located, and a paging system frame SFNPO = SFN SSB_i i.e. the paging system frame is in the system frame where the SSB is located;

[0169] wherein u is the subcarrier spacing, i is the SSB index, is the number of slots per system frame containing subcarrier spacing u, SFN SSB_i is the system frame where the SSB is located.

[0170] In some optional embodiments, the step S303 can be implemented by but not limited to the following manners:

[0172] The network-side device pages through PDCCH in the first paging slot and the second paging slot in the paging system frame.

[0173] As described above, the first SIB1 slot and the second SIB1 slot are the slots in which the network-side device transmits SIB1 through PDCCH; based on this, the network-side device of the present embodiment transmits SIB1 through PDCCH in each first SIB1 slot and each second SIB1 slot in the paging system frame;

[0174] The first paging slot and the second paging slot are the slots in which the network-side device pages through PDCCH; based on this, the network-side device of the present embodiment pages through PDCCH in each first paging slot and the second paging slot in the paging system frame.

[0175] Correspondingly, the step S304 can be implemented by but not limited to the following manners:

[0177] The terminal listens to the PDCCH of paging in the first paging slot and the second paging slot in the paging system frame.

[0178] As described above, the first SIB1 slot and the second SIB1 slot are the slots in which the terminal listens to the PDCCH of SIB1; in the DRX scenario, the terminal will sleep in the listening interval, based on this, the terminal of the present embodiment needs to wake up for pre-synchronization in each first SIB1 slot and each second SIB1 slot in the paging system frame, and the pre-synchronization result is used for receiving paging;

[0179] The first paging time slot is a time slot in which the terminal monitors a PDCCH of the second paging time slot.

[0180] Referring to FIG. 6, a schematic diagram of time slot information in a set of system frames (two paging system frames) provided in this embodiment is shown.
