Description

The technical field to which the invention belongs

[0001] The present application relates to the field of communication, and more specifically, to a method for transmitting a paging message, a terminal device, and a network device.

State of the art

[0069] FIG. 1 is a schematic diagram of a paging event in a Long Term Evolution (LTE) system. A paging frame in an LTE system may include four paging events. The length of the time domain resource occupied by each paging event is one subframe. As shown in FIG. 1, the location distribution of the four paging events is as follows: subframe 0, subframe 4, subframe 5, and subframe 9. Specifically, the network device may send a paging message in each of subframe 0, subframe 4, subframe 5, and subframe 9. The terminal device may monitor in four subframes to obtain a paging message corresponding to the terminal device.

[0070] In the future wireless communication system, beamforming technology is used to limit the energy of the transmitted signal in the direction of the beam in order to improve the reception efficiency of the signal. Beamforming technology can effectively extend the transmission range of the radio signal and reduce signal interference, thereby achieving higher communication efficiency and more network capacity.

[0071] A network device in a system using beamforming technology can simultaneously provide multiple beams. Therefore, the network device needs to send a plurality of paging messages on a paging event so that terminal devices located in different beams can receive corresponding paging messages. The plurality of paging messages within a paging event have consecutive time-domain blocks, where each time-domain block is used to send a paging message. The time domain block may be a subframe.

[0072] For example, assuming that the network device can provide two beams at the same time, in a paging event, the network device uses two consecutive subframes to send two paging messages. Apparently, the position of a paging event in an LTE system and the number of subframes included in each paging event are not suitable for sending a paging message in a system using beamforming technology.

[0073] FIG. 2 is a schematic flowchart of a method for transmitting a paging message in accordance with an embodiment of the present application.

[0074] 201. The terminal device determines a paging target resource, where the paging target resource includes at least one of the following types of information: paging target event position information, paging target frame position information, and target paging frame position information. monitoring windows.

[0075] 202. The terminal device receives a paging target message on a paging target resource, where the paging target message is a paging message sent by the network device to the terminal device.

[0076] FIG. 2 shows a method for receiving a paging message by a terminal device in a communication system using beamforming technology.

[0077] The network device may send the paging message to the terminal device in a broadcast mode, or may directly send the paging message to the terminal device. This is not limited in this embodiment of the present application.

[0078] Optionally, in some embodiments, the paging target resource includes paging target event position information, the paging target event position information is the start position of the paging target event in the paging frame, the paging frame includes N paging events, N paging events are located in M time domain resources, and the target paging event is one of the N paging events, where N is a positive integer greater than or equal to 1 and M is a positive integer greater than or equal to equal to 1 and less than or equal to N.

[0079] When M is N, each PO is on a time domain resource. For example, N=M=4. PO 1 may be located on the first time domain resource, PO 2 may be located on the second time domain resource, PO 3 may be located on the third time domain resource, and PO 4 may be located on the fourth time domain resource.

[0080] When M is less than N, at least two POs use one time domain resource in a frequency division multiplexing manner. For example, N=4 and M=2. In this case, PO 1 and PO 2 may use the first time domain resource, and PO 3 and PO 4 may use the second time domain resource. In another example, PO 1, PO 2, PO 3 and PO 4 may use the same time domain resource in a time division multiplexing manner.

[0081] Each of the M time domain resources may include at least two time domain blocks. The time domain block may be a subframe, a slot, a mini-slot, a non-slot block, or the like. A block without slots may include multiple consecutive symbols. For example, a slotless block may include four consecutive symbols. In another example, a block without slots may include two consecutive symbols. In another example, a slotless block may include seven consecutive symbols. It can be understood that the specific number of symbols included in the non-slot block is merely intended to help one skilled in the art better understand the meaning of the non-slot block, but is not intended to specifically limit the non-slot block.

[0082] For example, in some embodiments, the time domain block may be a subframe. The number of subframes included in each of the M time domain resources is the same, and each time domain resource may include at least two subframes.

[0083] For another example, in some embodiments, a time domain block may be a slot. The number of slots included in each of the M time domain resources is the same, and each time domain resource may include at least two slots.

[0084] For another example, in some embodiments, a time domain block may be a mini-slot. The number of mini-slots included in each of the M time domain resources is the same, and each time domain resource may include at least two mini-slots.

[0085] For another example, in some embodiments, the number of non-slot blocks included in each of the M time domain resources is the same, and each time domain resource may include at least two non-slot blocks. The numbers of symbols included in any two of the at least two non-slot blocks are the same.

[0086] To help a person skilled in the art better understand the technical solutions of the present application, some specific examples are given in the description of this application. All specific examples are described using an example in which the time domain block is a slot or subframe. Based on specific examples, one skilled in the art can also obtain an implementation in which a time domain block is another block, such as a subframe, a mini-slot, or a non-slot block.

[0087] Optionally, in some embodiments, the position of the paging target event in the paging frame is associated with at least one of the subcarrier spacing, the time domain position of the synchronization signal block actually sent by the network device, and the time domain position of the possible signal block synchronization.

[0088] That the position of each of the M time domain resources in the paging frame is related to the subcarrier spacing may be that the position of each time domain resource in the paging frame also changes when the subcarrier spacing is different.

[0089] For example, it is assumed that M is 1 and that the time domain block is a slot. When the subcarrier spacing is 15 kHz, the start position or time domain position of the first time domain resource may be located in slot 5 in the paging frame. When the subcarrier spacing is 30 kHz, the start position or time domain position of the first time domain resource may be located in slot 10 in the paging frame. When the subcarrier spacing is 60 kHz, the start position or time domain position of the first time domain resource may be located in slot 20 in the paging frame. When the subcarrier spacing is 120 kHz, the start position or time domain position of the first time domain resource may be located in slot 40 in the paging frame.

[0090] That the position of each of the M time domain resources in the paging frame is associated with the start position of the sync packet set may be that the start position of the sync packet set is the same as the start position of each time domain resource in paging frame.

[0091] For example, it is assumed that M is 1 and that the time domain block is a slot. When the subcarrier spacing is 15 kHz, the start position or time domain position of the first time domain resource and the start position of the sync packet set may both be located in slot 5 in the paging frame. When the subcarrier spacing is 30 kHz, the start position or time domain position of the first time domain resource and the start position of the set of synchronization signal packets may both be located in slot 10 in the paging frame. When the subcarrier spacing is 60 kHz, the start position or time domain position of the first time domain resource and the start position of the sync packet set may both be located in slot 20 in the paging frame. When the subcarrier spacing is 120 kHz, the start position or time domain position of the first time domain resource and the start position of the sync packet set may both be located in slot 40 in the paging frame.

[0092] Optionally, in some embodiments, the terminal device itself may determine paging event information. In particular, the terminal device may determine the start position of the paging target event in the paging frame based on the value of M.

[0093] Optionally, in some embodiments, that the terminal device determines the position of the paging target event time domain resource in the paging frame may determine the position of the first time domain block in the paging target event time domain resource in the paging frame. In other words, that the terminal device determines the location of the paging target event time domain resource in the paging frame may determine the start location of the paging target event time domain resource in the paging frame. The number of time domain blocks included in each of the M time domain resources is known to the terminal device. In other words, the length of each time domain resource is known to the terminal device. Therefore, after determining the position of the first time domain block in the time domain resource of the paging target event in the paging frame, the terminal apparatus can determine the specific position of the time domain resource of the paging target event in the paging frame.

[0094] Optionally, in some embodiments, M=1. In this case, only one time domain resource is included. In this case, the start position of the paging target event in the paging frame is time domain block 0 in the paging frame.

[0095] Optionally, in other embodiments, M=1 and the start position of the paging target event in the paging frame is a time domain block K ₁ /2 in the paging frame. K ₁ is a positive integer and K can be exactly divided by 2.

[0096] It should be understood that the value of K ₁ should be no more than twice the number of time domain blocks included in one paging frame.

[0097] For example, when the subcarrier spacing is 15 kHz, the number of slots included in the frame is 10. In particular, the paging frame may include slots 0-9. In this case, the start position of the paging target event in the paging frame may be any of slots 1-9 in the paging frame.

[0098] In another example, when the subcarrier spacing is 30 kHz, the number of slots included in the frame is 20. In particular, the paging frame may include slots 0-19. In this case, the start position of the paging target event in the paging frame may be any of slots 1-19 in the paging frame.

[0099] For another example, when the subcarrier spacing is 60 kHz, the number of slots included in the frame is 40. In particular, the paging frame may include slots 0-39. In this case, the start position of the paging target event in the paging frame may be any of slots 1-39 in the paging frame.

[0100] In another example, when the subcarrier spacing is 120 kHz, the number of slots included in the frame is 80. In particular, the paging frame may include slots 0-79. In this case, the start position of the paging target event in the paging frame may be any of slots 0-79 in the paging frame.

[0101] Optionally, in some embodiments, K ₁ is the number of time domain blocks included in one paging frame. For example, a time domain block is assumed to be a slot. When the subcarrier spacing is 15 kHz, the start position of the paging target event in the paging frame may be slot 5 in the paging frame. When the subcarrier spacing is 30 kHz, the start position of the paging target event in the paging frame may be slot 10 in the paging frame. When the subcarrier spacing is 60 kHz, the start position of the paging target event in the paging frame may be slot 20 in the paging frame. When the subcarrier spacing is 120 kHz, the start position of the paging target event in the paging frame may be slot 40 in the paging frame.

[0102] It is understood that slot x in this embodiment of the present application may also be referred to as slot x and denotes a slot whose slot index is x (x is a positive integer greater than or equal to 0). For example, slot 0 may also be referred to as slot 0 and denotes the slot at index 0; and slot 5 may also be referred to as slot 5 and denotes a slot whose index is 5. Similarly, a time domain time block in this embodiment of the present application may also be referred to as time domain block x and denotes a time domain block whose index is x; subframe x may also be referred to as subframe x and denotes a subframe whose subframe index is x; mini-slot x may also be referred to as mini-slot x and denotes a mini-slot whose mini-slot index is x; and block x without slots may also be referred to as block x without slots, and denotes a block without slots, the index of the block without slots is x.

[0103] It is understood that slot x in the paging frame is the (x+1)th slot in the paging frame. For example, slot 0 in the paging frame is the first slot in the paging frame, and slot 5 in the paging frame is the sixth slot in the paging frame. Similarly, time domain block x in the paging frame is the (x+1)th time domain block in the paging frame; subframe x in the paging frame is the (x+1)th subframe in the paging frame; mini-slot x in the paging frame is the (x+1)-th mini-slot in the paging frame; and the non-slot block x in the paging frame is the (x+1)-th non-slot block in the paging frame.

[0104] Optionally, in some embodiments, M=1 and the start position of the paging target event in the paging frame may be a time domain block to receive by the terminal device of the synchronization signal block in the paging frame. In other words, the PO and the sync block may use the same time domain block. This can reduce time domain resource occupancy by the PO. Thus, the stored time domain resource can be used to convey other information.

[0105] Optionally, in some embodiments, M=1 and the start position of the paging target event in the paging frame may be the time domain block following the time domain block for receiving the last synchronization signal block in the paging frame by the terminal device. Still, for example, a time domain block is a slot. The subcarrier spacing is assumed to be 15 kHz. If the last sync block received by the terminal device is located in slot 6, the first time domain block is slot 7.

[0106] The terminal device may determine the position of the time domain block of the candidate SSB and the position of the time domain block of the actually transmitted SSB based on the SSB position indication information sent by the network device. It can be understood that the SSB actually transmitted is the SSB actually sent by the network device. The possible SSB may also be referred to as the SSB that can be transmitted. The terminal device may receive the SSB in the position where the candidate SSB is. The actually transmitted SSB may also be referred to as the received SSB. The terminal device finally receives the SSB at the time domain position where the network device actually sends the SSB.

[0107] The network device may indicate the position of the SSB using the RMSI bit mapping information.

[0108] For example, for a frequency band above 6 GHz, one set of sync packets has a maximum of 64 SSBs. The 64 SSBs can be grouped into eight groups. The network device may use 8-bit information to indicate whether each SSB group has been sent. Each SSB group can include eight SSBs. The network device may use 8-bit information to indicate whether eight SSBs have been sent. The states about whether SSBs are sent in each SSB group are negotiated. Therefore, the network device can use the SSB position indication information, which is 16 bits long, to indicate the position of the time domain block for SSB transmission and the position of the time domain block of the actually transmitted SSB. For example, the SSB position indication information is 1101100110100011. The first eight bits in 16 bits may indicate group information. The group information is 11011001, which may indicate that the SSBs in group 0, group 1, group 3, group 4, and group 7 have actually been sent. The last eight bits in 16 bits may indicate intragroup information. The intragroup information is 10100011 which indicates that SSB 0, 2, 6 and 7 in the group has been sent.

[0109] The terminal device may determine two types of SSBs, where one type is the SSB actually sent by the network device, and the other type is the possible SSB. Still using 1101100110100011 as an example of SSB position indication information, the SSBs actually sent by the network device are SSBs 0, 2, 6 and 7 in groups 0, 1, 3, 4 and 7. All possible SSBs are SSBs in groups from 0 to 7.

[0110] The network device may also send the SSB time index to the terminal device. The SSB time index is used to indicate the location of the resource in the time domain, which can be used by the network device to send the SSB. Thus, the terminal apparatus determines, based on the SSB time index and the SSB position indication information, the position of the SSB time domain resource actually sent by the network device and the time domain position of the possible SSB resource.

[0111] Optionally, in some embodiments, M is 2, the start position of the first of the M time domain resources may be time domain block 0 in the paging frame, and the start position of the second of the M time domain resources may be block K₂/2 time domain in the paging frame, where K₂ - this is a positive integer that is greater than 2 and can be exactly divisible by 2. Optionally, in some embodiments, the time domain resource in which the paging target event is located can be the first time domain resource. Optionally, in other embodiments, the time domain resource in which the paging target event is located may be a second time domain resource. In other words, the start position of the paging target event in the paging frame may be the start position of the first time domain resource or the start position of the second time domain resource. Specifically, the start position of the paging target event in the paging frame is time domain block 0 in the paging frame or block K₂/2 time domain in the paging frame.

[0112] Like K ₁ , the value of K ₂ should be no more than twice the number of time domain blocks included in one paging frame.

[0113] Optionally, in some embodiments, M is 2, at least one time domain block may be included between the first time domain block in the first of the M time domain resources and the first time domain block in the second of the M time domain resources.

[0114] Using 15 kHz subcarrier spacing as an example, when the start position or time domain position of the first time domain resource is slot 0, the start position or time domain position of the second time domain resource may be any of slots 2-8. It should be understood that if the first time domain block in the second time domain resource is slot 9, when the next subframe is also a paging frame, the start or time domain positions of the two time domain blocks in different paging frames may be consecutive. Similarly, when the start position or time domain position of the first time domain resource is slot 1, the start position or time domain position of the second time domain resource may be any of slots 3-8. Similarly, when the start position or time domain position of the first time domain resource is slot 2, the start position or time domain position of the second time domain resource may be any of slots 4-8. Similarly, when the start position or time domain position of the first time domain resource is slot 3, the start position or time domain position of the second time domain resource may be any of slots 5-8. Similarly, when the start position or time domain position of the first time domain resource is slot 4, the start position or time domain position of the second time domain resource can be any of the slots numbered 6 to 8. Similarly, when the start position of the first time domain resource is slot 5, the start position or time domain position of the second time domain resource can be any of slot numbers 7 and 8. Similarly, when the start position or time domain position of the first time domain resource is slot 6, the start position or time domain position of the second time domain resource may be slot 8.

[0164] In Table 14-Table 20, PO 0 indicates the position slot index of the first of the two paging resources in the paging frame, and PO 1 indicates the position slot index of the second of the two paging resources in the paging frame.

[0165] In addition, in the above embodiment, the terminal device can directly determine the location of the start position or time domain position of the target paging event in the paging frame. The number of time domain blocks included in each of the M time domain resources is known to the terminal device. Thus, in other embodiments, the terminal device may also determine the position of any time domain block in each time domain resource in a paging frame. Thus, the terminal device can indirectly determine the location of the start position or time domain position of the target paging event in the paging frame.

[0166] 15 kHz subcarrier spacing is used as an example. M is 1. Each time domain resource is assumed to include three time domain blocks. Each time a time domain block is a slot. If the terminal device determines that the second time domain block in the time domain resource is slot 1, the terminal device may determine that the start position of the paging target event is slot 0.

[0167] In some embodiments, the positions of the M time domain resources may also be associated with the half-frame indication. time domain of the paging target event in the paging frame based on the half-frame indication sent by the network device. The half-frame indication is used to indicate the position of the SSB or sync signal set.

[0168] In some embodiments, the time domain resource positions M may also be associated with a frequency division multiplexing indication of the paging message and the SS block. When the terminal device itself determines the start position or time domain position of the paging target event in the paging frame, the terminal device may also determine the start position or time domain position of the paging target event in the paging frame based on the frequency division multiplexing indication sent through a network device.

[0169] For example, if the half-frame indication is 0, then the start position of the SSB or sync packet set is in the second half-frame of the paging frame. Accordingly, the start position or time domain position of the paging target event in the paging frame may be located in the second field frame. As another example, if the half-frame indication is 1, then the start position of the SSB or sync packet set is in the first half-frame of the paging frame. Accordingly, the start position or time domain position of the paging target event in the paging frame may be located in the first field frame.

[0170] For example, if the half-frame indication is 0, the start position of the SSB or sync packet set is in the first half-frame of the paging frame. Accordingly, the start position or time domain position of the paging target event in the paging frame may be located in the first field frame. For example, if the half-frame indication is 1, the start position of the SSB or sync packet set is in the second half-frame of the paging frame. Accordingly, the start position or time domain position of the paging target event in the paging frame may be located in the second field frame.

[0171] In some embodiments, when there are multiple paging events in one paging frame, the PO index in frequency division multiplexing with SSB in the frame may be predetermined. For example, the first PO in the frequency division multiplexing with SSB in the frame may be determined; the second PO in the frequency division multiplexing with SSB in the frame may be determined; a third PO in frequency division multiplexing with SSB in the frame may be determined; or a fourth PO in the frequency division multiplexing with SSB in the frame may be determined. Alternatively, the determination may be based on SSB positions. For example, when SSB is in the first half frame and the number of POs is 4, the first PO whose index is 0 or the second PO whose index is 1 may be determined as a PO in SSB frequency division multiplexing; or when the SSB is in the second half frame and the number of POs is 4, the third PO whose index is 2 or the fourth PO whose index is 3 may be determined as a PO in SSB frequency division multiplexing. When the number of POs in a frame is 2, the first PO whose index is 0 or the second PO whose index is 1 may be determined as a PO in SSB frequency division multiplexing. In addition, the determination may be based on the position of the SSB. For example, when SSB is in the first half frame, the first PO whose index is 0 may be determined as a PO in SSB frequency division multiplexing. For example, when SSB is in the second half-frame, the second PO whose index is 1 may be determined as a PO in SSB frequency division multiplexing.

[0172] Optionally, in some embodiments, when the start position or time domain position of the paging target event in the paging frame is in the first half frame, the start position or time domain position of the paging target event in the paging frame may start from a subframe 0 (eg, may be subframe 0). When the start position or time domain position of the paging target event in the paging frame is in the second half-frame, the start position or time domain position of the paging target event in the paging frame may start from subframe 5 (e.g., may be subframe 5). Optionally, in other embodiments, when the subcarrier spacing is 15 kHz, when the start position or time domain position of the paging target event in the paging frame is in the first half frame, the start position or time domain position of the paging target event in the paging frame may start at slot 0 (eg, may be slot 0); or when the start position or time domain position of the paging target event in the paging frame is in the second half frame, the start position or time domain position of the paging target event in the paging frame may start from slot 5 (e.g., may be slot 5) . When the subcarrier spacing is 30 kHz, when the start position or time domain position of the paging target event in the paging frame is in the first half frame, the start position or time domain position of the paging target event in the paging frame may start from slot 0 (e.g., , can be slot 0); or when the start position or time domain position of the paging target event in the paging frame is in the second half-frame, the start positions M of the time domain resources may start from slot 10 (eg, may be slot 10). When the subcarrier spacing is 60 kHz, when the start position or time domain position of the paging target event in the paging frame is in the first half frame, the start position or time domain position of the paging target event in the paging frame may start from slot 0 (e.g., , can be slot 0); or when the start position or time domain position of the paging target event in the paging frame is in the second half-frame, the start positions M of the time domain resources may start from slot 20 (eg, may be slot 20). When the subcarrier spacing is 120 kHz, when the start position or time domain position of the paging target event in the paging frame is in the first half frame, the start position or time domain position of the paging target event in the paging frame may start from slot 0 (e.g., , can be slot 0); or when the start position or time domain position of the paging target event in the paging frame is in the second half frame, the start position or time domain position of the paging target event in the paging frame may start from slot 40 (e.g., may be slot 40) .

[0173] Of course, the start position or time domain position of the paging target event in the paging frame may also start from a different subframe and is unrelated to the half frame indication.

[0174] Optionally, in some embodiments, when the sync burst period is 5 ms, the start position or time domain position of the paging target event in the paging frame may start from subframe 0 (e.g., may be subframe 0), or the start the position or time domain position of the paging target event in the paging frame may start at subframe 5 (eg, may be subframe 5). Optionally, in other embodiments, when the subcarrier spacing is 15 kHz, the start position or time domain position of the paging target event in the paging frame may start at slot 0 (e.g., may be slot 0) or the start position or time domain position The paging target event in the paging frame may start at slot 5 (eg, may be slot 5). When the subcarrier spacing is 30 kHz, the start position or time domain position of the paging target event in the paging frame may start at slot 0 (for example, may be slot 0), or the start positions of the M time domain resources may begin at slot 10 (for example, can be slot 10). When the subcarrier spacing is 60 kHz, the start position or time domain position of the paging target event in the paging frame may start at slot 0 (for example, may be slot 0), or the start positions of the M time domain resources may begin at slot 20 (for example, can be slot 20). When the subcarrier spacing is 120 kHz, the start position or time domain position of the paging target event in the paging frame may start at slot 0 (e.g., may be slot 0) or the start position or time domain position of the paging target event in the paging frame. the call may start at slot 40 (eg, may be slot 40).

[0175] Using the half-frame indication, the terminal device may also determine the start position of the SSB or sync burst set, and the PO may use the same time domain resource as the SSB or sync burst set in a time division multiplexing manner.

[0176] Optionally, in other embodiments, the terminal device may further determine the start position or duration of the paging target event in the paging frame based on the paging position information sent by the network device. The paging position information is used to indicate the time domain position of the paging target event in the paging frame.

[0177] The paging position information is associated with at least one of the subcarrier spacing, the time domain position of the synchronization signal block actually sent by the network device, and the time domain position of the possible synchronization signal block; or, in other words, the time domain positions of the M time domain resources in the paging frame are associated with at least one of the subcarrier spacing, the time domain position of the synchronization signal block actually sent by the network device, and the time domain position of the possible synchronization signal block .

[0178] Optionally, in some embodiments, the paging position information may include the location of the starting position of the first of the M time domain resources in the paging frame. When M is a positive integer greater than 1, the number of time domain blocks included in any two of the M time domain resources is the same. In other words, the paging position information may indicate, by indicating the time domain position of the M time domain resources in the paging frame, the time domain position of the paging target event in the paging frame.

[0179] Optionally, in some embodiments, the value of M and the number of time domain blocks included in each of the M time domain resources are known to the terminal device.

[0180] Optionally, in some embodiments, the specific time domain location of the paging target event at M time domain locations is also known to the terminal device.

[0181] "Known" in the present application may be that the configuration information is notified in advance to the terminal device by the network device, or the information is negotiated by the network device and by the terminal device, or indicated in the protocol, or output by the terminal device based on the configuration parameter .

[0182] Optionally, in other embodiments, the value of M and the total length M of the time domain resources are known to the terminal device. Thus, the terminal device can determine, based on the value of M and the total length M of the time domain resources, the number of time domain blocks included in each time domain resource.

[0183] When M is 1, the paging position information is the start position of the paging target event in the paging frame. The terminal device can directly determine the start position of the paging target event in the paging frame based on the paging position information.

[0184] When M is 2 or 4, when the terminal device determines the start position of the first time domain resource in the paging frame, the terminal device may determine the start position of the paging target event in the paging frame based on the time domain resource on which the target is located. paging event.

[0185] Optionally, in some embodiments, the M time domain resources may be consecutive time domain resources. Thus, when the start location of the first time domain resource in the paging frame is determined, the terminal device can determine the start location of each time domain resource in the paging frame using the following formula:

where PO _{i_s} denotes the start position location of the time domain resource whose index is i_s in the paging frame, O denotes the start location of the first time domain resource in the paging frame, i_s is the index of the time domain resource, and Length_PO is the number of time domain blocks, included in one time domain resource. The index of the mth time domain resource in the M time domain resources is m - 1, where m=1,…,M. For example, the index of the first time domain resource is 0, the index of the second time domain resource is 1, the index of the third time domain resource is 2, and the index of the fourth time domain resource is 3. It is clear that if i_s in Formula 1.1 is the index of the time domain resource, in which the paging target event is located, the terminal device can directly determine the position of the paging target event in the paging frame using Formula 1.1.

[0186] 15 kHz subcarrier spacing is used as an example. It is assumed that M is 2 and that each time domain resource includes two time domain blocks. The two time domain resources are consecutive time domain resources. The paging position information is assumed to indicate that the start position of the first time domain resource is slot 0. According to formula 1.1, O is 0, Length_PO is 2, and i_s is 1. Thus, the terminal device can determine that the start position of the second time domain resource is slot 2.

[0187] Optionally, in other embodiments, the M time domain resources may be M non-consecutive time domain resources. The M non-consecutive time domain resources are the M time domain resources in P consecutive time domain resources. In order to convey information other than the paging message, other time domain resources in P consecutive time domain resources other than the M time domain resources have been defined. Said information other than the paging message may be uplink information or may be other downlink information (eg, SSB). P is a positive integer greater than M.

[0188] Thus, when the start location of the first time domain resource in the paging frame is determined, the terminal device can determine the start location of each time domain resource in the paging frame using the following formula:

where PO_{i_s}denotes the location of the start position of the time domain resource whose index is i_s in the paging frame, O denotes the location of the start position of the first time domain resource in the paging frame, i_s is the index of the time domain resource, Length_PO is the number of time domain blocks included in one resource time domain, and Length_offset_{i_s} stands for the number of time domain blocks that are between the start position of the time domain resource whose index is i_s and the time domain resource whose index is i_s-1 and are used to convey other information. It is understood that if i_s in Formula 1.2 is the index of the time domain resource in which the paging target event is located, the terminal device can directly determine the position of the paging target event in the paging frame using Formula 1.2.

[0189] 15 kHz subcarrier spacing is still used as an example. It is assumed that M is 2 and that each time domain resource includes two time domain blocks. The terminal device has determined that slots 2-5 are used to send information other than the paging message. The paging position information is assumed to indicate that the start position of the first time domain resource is slot 0. According to formula 1.2, O is 0, Length_PO is 2, and Length_offset_{i_s}is 4. Thus, the terminal device can determine that the start position of the second time domain resource is slot 6.

[0190] Optionally, in some embodiments, the paging position information may include a total length M of the time domain resources. In addition, the location of the start position or the position in the time domain of the first time domain resource is known to the terminal device. In addition, when M is a positive integer greater than 1, the number of time domain blocks included in any two of the M time domain resources is the same.

[0191] Optionally, in some embodiments, the value of M is known to the terminal device. Thus, the terminal device can determine, based on the total length M of the time domain resources and the value of M, the number of time domain blocks included in each time domain resource. In this case, the initial or time domain positions of the M time domain resources, the number of time domain blocks included in each time domain resource, and the indexes of the time domain resources are all known to the terminal device. When the M time domain resources are M consecutive time domain resources, the terminal device may determine the time domain position of the paging target event in the paging frame using Formula 1.1. When the M time domain resources are M non-consecutive time domain resources, the terminal device may determine the time domain position of the paging target event in the paging frame using Formula 1.2.

[0192] Optionally, in other embodiments, the number of time domain blocks included in each of the M time domain resources is known to the terminal device. Thus, the terminal device can determine the index of each time domain resource based on the total length M of the time domain resources and the number of time domain blocks included in each of the M time domain resources. In this case, the initial or time domain positions of the M time domain resources, the number of time domain blocks included in each time domain resource, and the indexes of the time domain resources are all known to the terminal device. When the M time domain resources are M consecutive time domain resources, the terminal device may determine the time domain position of the paging target event in the paging frame using Formula 1.1. When the M time domain resources are M non-consecutive time domain resources, the terminal device may determine the time domain position of the paging target event in the paging frame using Formula 1.2.

[0193] Optionally, in some embodiments, the paging position information may include the total length of the M time domain resources and the location of the start position or time domain position of the first of the M time domain resources in the paging frame. The value of M or the number of time domain blocks included in each time domain resource is known to the terminal device. In addition, when M is a positive integer greater than 1, the number of time domain blocks included in any two of the M time domain resources is the same.

[0194] In this case, the terminal device may determine the initial positions of the M time domain resources, the number of time domain blocks included in each of the M time domain resources, and indexes of the time domain resources. When the M time domain resources are M consecutive time domain resources, the terminal device may determine the time domain position of the paging target event in the paging frame using Formula 1.1. When the M time domain resources are M non-consecutive time domain resources, the terminal device may determine the time domain position of the paging target event in the paging frame using Formula 1.2.

[0195] When the paging position information includes the total length of the M time domain resources and/or the location of the starting position of the first of the M time domain resources in the paging frame, the network device may indicate the positions of the M time domain resources in the paging frame using fewer bits.

[0196] In other embodiments, the paging position information may include the location of the start position or time domain position of each of the M time domain resources in the paging frame. Thus, the terminal device can directly determine the position of each time domain resource in the paging frame without itself calculating the position of each time domain resource in the paging frame. In this case, the configured position of the paging event in the paging frame may be determined based on the number of paging events in the discontinuous reception cycle. For example, when the number of paging events is 4, k_one bits are needed to indicate the position of each PO, where k_one is a positive integer greater than or equal to 1. The value of k_one associated with subcarrier spacing. When the number of paging events is 4, the paging position information may include 4*k_one bits (* means multiplication sign). For example, if the subcarrier spacing is 15 kHz, the value of k_one maybe be 2 bits; or if the subcarrier spacing is 30 kHz, the value of k_one may be 3 or 4. With a subcarrier spacing of 60 kHz or 120 kHz, the value of k_one maybe 3 or 4.

[0197] It can be understood that the length of the paging position information is related to the maximum number of possible positions for the start position or time domain position of each slot in the paging frame, and the value of M.

[0198] 15 kHz subcarrier spacing is used as an example. The value of M is assumed to be 4.

[0199] In some embodiments, the start position or time domain position of the first time domain resource may be slot 0-6. The start position or time domain position of the second time domain resource may be in slot 1-7. The start position or time domain position of the third time domain resource may be in slot 2-8. The start position or time domain position of the fourth time domain resource may be located in slot 2-8. As can be seen, there are six possible positions in the paging frame for each time domain resource. In this case, the location of the start position or time domain position of each time domain resource in the paging frame may be indicated using three bits.

[0200] Optionally, in other embodiments, the start position or time domain position of the first time domain resource may be in slot 0-3. The start position or time domain position of the second time domain resource may be in slot 2-5. The start position or time domain position of the third time domain resource may be in slot 4-7. The start position or time domain position of the fourth time domain resource may be located in slot 5-8. As can be seen, there are four possible positions in the paging frame for each time domain resource. In this case, the start position or time domain location of each time domain resource in the paging frame may be indicated using two bits.

[0201] Optionally, the position of each of the M time domain resources may also be associated with a half-frame indication. In other words, the location of the start position or time domain position of each of the M time domain resources in the paging frame may be indicated using the half-frame indication and the specific position indication together.

[0202] For example, in some embodiments, the paging position information may include three bits. The first of the three bits is the half-frame indication. The half-frame indication is used to indicate that the start position or time-domain position of the time-domain resource is in the first half-frame or the second half-frame, and the last two of the three bits are the specific position indication. The specific position indication may be used to indicate the specific time domain block of the half-frame in which the start position or time domain position of the time domain resource resides.

[0203] Optionally, in some embodiments, the half-frame indication and the particular position indication may be multiple consecutive bits. In other words, the network device can use the message to carry the half-frame indication and indicate the particular position.

[0204] Optionally, in other embodiments, the half-frame indication and the particular position indication may be separately indicated to the terminal device. In other words, the network device can indicate the half-frame indication and the specific position indication to the terminal device using two messages.

[0205] Specifically, if the half-frame indication is 0, the indicated start position or time domain position of the time-domain resource is in the first half-frame of the paging frame, that is, slots 0-4; or if the half-frame indication is 1, the indicated start position or time-domain position of the time-domain resource is in the second half-frame of the paging frame, ie, from slots 5-9. If the specific position indication is 00, the specified start position or time domain position of the time domain resource is in the first slot; if the specific position indication is 01, the specified start position or time domain position of the time domain resource is in the second slot; if the specific position indication is 10, the specified start position or time domain position of the time domain resource is in the third slot; or, if the specific position indication is 11, the specified start position or time domain position of the time domain resource is in the fourth slot.

[0206] For example, if the paging position information is 010, the specified start position or time domain position of the time domain resource is the third slot in the first half frame, that is, slot 2. In another example, if the paging position information is 110, the indicated start position or time domain position of the time domain resource is the third slot in the second half frame, i.e. slot 7.

[0207] 15 kHz subcarrier spacing is still used as an example. The value of M is assumed to be 2.

[0208] Optionally, in some embodiments, the start position or time domain position of the first time domain resource may be slot 0 to 8, and the start position or time domain position of the second time domain resource may be slot 2-8. As can be seen, there are a maximum of nine possible positions in a paging frame for each time domain resource. In this case, the start position or time domain location of each time domain resource in the paging frame may be indicated using four bits.

[0209] Optionally, in other embodiments, the start position or time domain position of the first time domain resource may be slot 0 to 3. The start position or time domain position of the second time domain resource may be located in slot 5-8. As can be seen, there are four possible positions in the paging frame for each time domain resource. In this case, the start position or time domain location of each time domain resource in the paging frame may be indicated using two bits.

[0210] Similarly, when the value of M is 2, the start position or time domain position of each time domain resource in the paging frame can also be indicated by sharing the half-frame indication and the specific position indication. The specific implementation is similar to the implementation in which the value of M is 4. Details are not described here again.

[0211] Optionally, in other embodiments, the location of the start positions or time domain positions of the two time domain resources in the paging frame may be specified in advance. For example, it is specified in advance that the start position or time domain position of either of the two time domain resources in the paging frame is in slots 0-3. Thus, two bits may be used to indicate the location of the start position or time domain position of either of the two time domain resources in the paging frame. For another example, it is specified in advance that the start position or time domain position of either of the two time domain resources is in the first half frame of the paging frame, ie slots 0-4. Thus, three bits may be used to indicate the location of the start position or time domain position of either of the two time domain resources in the paging frame. For another example, it is specified in advance that the start position or time domain position of either of the two time domain resources is in the second half frame of the paging frame, ie slots 5-9. Thus, three bits may be used to indicate the location of the start position or time domain position of either of the two time domain resources in the paging frame. For another example, it is indicated in advance that the start position or time domain position of the first of the two time domain resources is in the first half frame of the paging frame, that is, slots 0-4. Thus, three bits may be used to indicate the location of the start position or time domain position of the first time domain resource in the paging frame. In addition, it is indicated in advance that the start position or time domain position of the second of the two time domain resources is in the second half frame of the paging frame, that is, slots 5-9. Thus, three bits may be used to indicate the location of the start position or time domain position of the second time domain resource in the paging frame.

[0212] The start position of the paging event is associated with the SSB frequency division multiplexing indication. When there is only one PO, the initial position of the PO may not be configured. When there are two POs, the start position of one PO can be configured.

[0213] 15 kHz subcarrier spacing is still used as an example. The value of M is assumed to be 1.

[0214] Optionally, in some embodiments, the start position or time domain position of the first time domain resource may be slot 0-8. As can be seen, there are a maximum of nine possible positions in a paging frame for each time domain resource. In this case, the start position or time domain location of each time domain resource in the paging frame may be indicated using four bits.

[0215] Optionally, in other embodiments, the start position or time domain position of the first time domain resource may be slot 0-7. As can be seen, there are eight possible positions in the paging frame for each time domain resource. In this case, the start position or time domain location of each time domain resource in the paging frame may be indicated using two bits.

[0216] Optionally, in other embodiments, the start position or time domain position of the first time domain resource may be slot 0-3. As can be seen, there are four possible positions in the paging frame for each time domain resource. In this case, the start position or time domain location of each time domain resource in the paging frame may be indicated using two bits.

[0217] 30 kHz subcarrier spacing is used as an example. The value of M is assumed to be 1.

[0218] Optionally, in some embodiments, the start position or time domain position of the first time domain resource may be located in slot 0-18. The paging position information may directly indicate the position of the first time domain resource. In this case, the length of the paging position information is five bits.

[0219] Optionally, in some embodiments, the paging position information may indicate the position of the first time domain resource by sharing the half-frame indication and the particular position indication. For a specific implementation, refer to an example in which the subcarrier spacing is 15 kHz and the value of M is 4. Details are not described here again.

[0220] Optionally, in other embodiments, the location of the start position or time domain position of the time domain resource in the paging frame may be predetermined. For example, it is indicated in advance that the start position or time domain position of the time domain resource in the paging frame is in slot 0-7. Thus, three bits may be used to indicate the location of the start position or time domain position of the time domain resource in the paging frame. For another example, it is specified in advance that the start position or time domain position of the time domain resource in the paging frame is in slot 10-17. Thus, three bits may be used to indicate the location of the start position or time domain position of the time domain resource in the paging frame.

[0221] The implementation in which the subcarrier spacing is 30 kHz and the value of M is 2 is similar to the specific implementation in which the subcarrier spacing is 15 kHz and the value of M is 2. Details are not described here again. The implementation in which the subcarrier spacing is 30 kHz and the value of M is 4 is similar to the specific implementation in which the subcarrier spacing is 15 kHz and the value of M is 4. Details are not described here again.

[0222] An implementation in which the subcarrier spacing is 60 kHz or 120 kHz is similar to an implementation in which the subcarrier spacing is 15 kHz or 30 kHz. Details are not described here again.

[0223] Optionally, in some embodiments, the paging position information includes a paging position index, where the paging position index is used to indicate time domain positions of M time domain resources in a paging frame. More specifically, the paging position index is used to indicate the location of the starting position of each of the M time domain resources in the paging frame.

[0224] In the positions of the time domain resources shown in Tables 1-20, the positions of the time domain resources in each group may correspond to one index. One time domain resource group specifies all M time domain resources. One paging position index may be allocated for each time domain resource group based on tables 1-21. Each paging position index corresponds to the positions of M time domain resources in the paging frame. For example, table 21 is the result obtained by adding the paging position index based on table 1.

Table 21

index PO0 PO 1 PO2 PO 3 index PO0 PO 1 PO2 PO 3 0 0 2 four 6 eight 0 3 6 eight one 0 2 four 7 9 0 four 6 eight 2 0 2 four eight ten one 3 5 7 3 0 2 5 7 eleven one 3 5 eight four 0 2 5 eight 12 one 3 6 eight 5 0 2 6 eight 13 one four 6 eight 6 0 3 5 7 fourteen 2 four 6 eight 7 0 3 5 eight fifteen one 3 6 eight

[0225] As shown in Table 21, when the paging position index received by the terminal device is 4, the terminal device can determine that the initial positions of the four time domain resources are allocated in subframes 0, 2, 5, and 8.

[0226] The paging position information includes at least one of a start position and a duration of a paging target event in a paging frame.

[0227] When the paging message control resource set matches the RMSI control resource set, the maximum number of paging events in one frame or two frames is 1. This is to satisfy the beam sweep requirement. When the SSB and RMSI multiplexing method is frequency division multiplexing, the maximum number of paging events in a paging message in a DRX cycle may be determined based on the SSB period or the RMSI period. The frequency division multiplexing method may be pattern 1 and pattern 2. Specifically, pattern 1 is PDSCH RMSI frequency division multiplexing with SSB. Specifically, pattern 2 is PDSCH and PDCCH RMSI frequency division multiplexing with SSB. RMSI can also be SIB1. When the SSB and RMSI multiplexing method is time division multiplexing, the maximum number of paging events in a paging message in a DRX cycle may be determined based on the RMSI period. In time division multiplexing, the maximum number of paging events or paging frames in a DRX cycle is T/2, where T is a DRX cycle. In some implementations, the T DRX cycle is defined, eg, defined in the system, preconfigured, configured by the base station, or sent by the base station. In this case, the number of frames included in the T DRX frame is also determined. Alternatively, the two frames may be one paging frame, or the two frames include one paging event. In frequency division multiplexing, the maximum number of paging events or paging frames in a DRX cycle is 2T, T, T/2, T/4, T/8, and T/16. When the SSB period is 5 ms, the maximum number of paging events or paging frames in a DRX cycle is 2T. When the SSB period is 10 ms, the maximum number of paging events or paging frames in a DRX cycle is T. When the SSB period is 20 ms, the maximum number of paging events or paging frames in a DRX cycle is T/2. When the SSB period is 40 ms, the maximum number of paging events or paging frames in a DRX cycle is T/4. When the SSB period is 80 ms, the maximum number of paging events or paging frames in a DRX cycle is T/8. When the SSB period is 160 ms, the maximum number of paging events or paging frames in a DRX cycle is T/16. In frequency division multiplexing, the number of paging events or paging frames in a DRX cycle is 2T, T, T/2, T/4, T/8, and T/16. When the SSB period is 5 ms, the number of paging events or paging frames in a DRX cycle is 2T. When the SSB period is 10 ms, the number of paging events or paging frames in a DRX cycle is T. When the SSB period is 20 ms, the number of paging events or paging frames in a DRX cycle is T/2. When the SSB period is 40 ms, the number of paging events or paging frames in a DRX cycle is T/4. When the SSB period is 80 ms, the number of paging events or paging frames in a DRX cycle is T/8. When the SSB period is 160 ms, the number of paging events or paging frames in a DRX cycle is T/16.

[0228] When the control information of the paging message indicates that there is a separate search space, the start position of the paging event can also be configured separately. The start position of the paging event may be configured separately, and the configuration parameter may be configured based on the subcarrier spacing. For example, when one paging frame includes one paging event when the subcarrier spacing is 15 kHz, the slot indices that can be configured include some or all of the values of 0, 1, 2, 3, 4, 5, 6, 7, and 8, or some or all of the values of 0, 1, 2, 3, 4, 5, 6, and 7. For example, when one paging frame includes one paging event, when the subcarrier spacing is 30 kHz, indices that can be configured include some or all of the values from 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17 and 18, or some or all of the values 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, and 15. For example, when one paging frame includes one paging event when the sub-carrier spacing is 60 kHz, indices that may be configured include some or all of 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11 , 12, 13, 14, 15, 16, 17 , 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, and 39. For example, when one frame paging includes one paging event when the sub-carrier spacing is 120 kHz, indices that can be configured include some or all of the values of 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48, 49, 50, 51, 52, 53, 54, 55, 56, 57, 58, 59, 50, 61, 62, 63, 64, 65, 66, 67, 68, 69, 70, 71, 72, 73, 74, 75, 76, 77, 78, and 79. For example, when one paging frame includes includes two paging events, when the subcarrier spacing is 15 kHz, the indices that can be configured for the first paging event include some or all of the values of 0, 1, 2, 3, 4, 5, 6, 7, and 8, and indexes that can be configured for the second poi event. paging include some or all of the values of 1, 2, 3, 4, 5, 6, 7, 8, and 9. For example, when one paging frame includes two paging events when the subcarrier spacing is 30 kHz , indices that may be configured for the first paging event include some or all of the values of 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14 , 15, 16, 17, and 18, and indices that may be configured for the second paging event include some or all of the values of 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19 or some or all of 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13 , 14, and 15. For example, when one paging frame includes two paging events, when the subcarrier spacing is 60 kHz, the indices that can be configured for the first paging event include some or all of the values of 0, 1 , 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31 32 , 33, 34, 35, 36, 37, and 38, as well as indices that may be configured for the second paging event, include some or all of the values of 1, 2, 3, 4, 5, 6, 7, 8 , 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33 , 34, 35, 36, 37, 38, and 39. For example, when one paging frame includes two paging events when the subcarrier spacing is 120 kHz, the indices that can be configured for the first paging event include some or all of the values from 0, 1, 2, 3, 4, 5, 6., 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48, 49, 50, 51, 52, 53, 54, 55, 56, 57, 58, 59, 50, 61, 62, 63, 64, 65, 66, 67, 68, 69, 70, 71, 72, 73, 74, 75, 76, 77 and 78, as well as ind Exes that may be configured for the second paging event include some or all of the values of 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16 , 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41 , 42, 43, 44, 45, 46, 47, 48, 49, 50, 51, 52, 53, 54, 55, 56, 57, 58, 59, 50, 61, 62, 63, 64, 65, 66 , 67, 68, 69, 70, 71, 72, 73, 74, 75, 76, 77, 78, and 79. For example, when one paging frame includes four paging events when the subcarrier spacing is 15 kHz, the indices , which may be configured for the first paging event, include some or all of 0, 1, 2, 3, 4, 5, and 6; indices that may be configured for the second paging event include some or all of the values of 1, 2, 3, 4, 5, 6, and 7; indices that may be configured for the third paging event include some or all of 2, 3, 4, 5, 6, 7, and 8; and indices that may be configured for the fourth paging event include some or all of the values of 3, 4, 5, 6, 7, 8, and 9. For example, when one paging frame includes two paging events, when the sub-carrier spacing is 30 kHz, the indices that can be configured for the first paging event include some or all of 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11 , 12, 13, 14, 15 and 16; indices that may be configured for the second paging event include some or all of the values of 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16 and 17; indices that may be configured for the third paging event include some or all of the values of 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17 and 18; and indices that may be configured for the fourth paging event include some or all of the values of 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17 , 18, and 19, or some or all of the values of 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, and 15. For example, when one search frame paging event includes four paging events, when the subcarrier spacing is 60 kHz, indices that can be configured for the first paging event include some or all of the values of 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35 and 36; indices that may be configured for the second paging event include some or all of the values of 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36 and 37; indices that may be configured for the third paging event include some or all of the values of 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37 and 38; and indices that may be configured for the fourth paging event include some or all of the values of 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17 , 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, and 39. For example, when one frame paging event includes four paging events, when the subcarrier spacing is 120 kHz, indices that can be configured for the first paging event include some or all of the values of 0, 1, 2, 3, 4, 5, 6 , 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31 , 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48, 49, 50, 51, 52, 53, 54, 55, 56 , 57, 58, 59, 50, 61, 62, 63, 64, 65, 66, 67, 68, 69, 70, 71, 72, 73, 74, 75 and 76; indices that may be configured for the second paging event include some or all of the values of 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48, 49, 50, 51, 52, 53, 54, 55, 56, 57, 58, 59, 50, 61, 62, 63, 64, 65, 66, 67, 68, 69, 70, 71, 72, 73, 74, 75, 76 and 77; indices that may be configured for the third paging event include some or all of 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48, 49, 50, 51, 52, 53, 54, 55, 56, 57, 58, 59, 50, 61, 62, 63, 64, 65, 66, 67, 68, 69, 70, 71, 72, 73, 74, 75, 76, 77 and 78; and indices that may be configured for the fourth paging event include some or all of the values of 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15 , 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40 , 41, 42, 43, 44, 45, 46, 47, 48, 49, 50, 51, 52, 53, 54, 55, 56, 57, 58, 59, 50, 61, 62, 63, 64, 65 , 66, 67, 68, 69, 70, 71, 72, 73, 74, 75, 76, 77, 78, and 79. The paging event in the paging frame may be configured, where the values that may be configured include themselves 1, 2, 4 and 8, or 1, 2, 4 and 6, or 1, 2, 3 and 4, or 1, 2, 4, 8 and 16, or some or all of the values of 0, 1, 2, 3, 4, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15 and 16 or 1, 2 and 4 or 1 and 2 Advantage 1, 2 and 4 and also 1 and 2 and 1, 2, 4, and 8 is that they are each the numeric value 2 raised to the power for ease of presentation. For example, when there are eight paging events, three bits may be used to indicate the index of each PO. The advantage of 1 and 2 is that the number of paging events per frame is relatively small. When one frame includes four paging events.

[0229] Optionally, in other embodiments, the paging position index may directly indicate the time domain position of the target paging event in the paging frame. Still using table 21 as an example, table 21 shows that an index is set for each time domain resource group. In other embodiments, an index may be set for the location of each time domain resource. Thus, the terminal device can directly determine the time domain position or start position of the paging target event in the paging frame based on the index.

[0230] Optionally, in some embodiments, the paging target resource includes paging frame position information, and the paging frame position information includes a frame number for the paging frame. In this case, what the terminal device determines the paging target resource includes: the terminal device determines the frame number for the paging frame based on the offset of the paging frame. The paging frame offset block is a frame.

[0231] The paging frame offset is associated with at least one of the sync block period, the time domain position of the sync block actually sent by the network device, and the time domain position of the possible sync block. The position in the time domain of the synchronization signal block actually sent by the network device may be one of a system frame number, subframe, slot, or symbol. Likewise, the position in the time domain of a candidate sync block may be one of a system frame number, subframe, slot, or symbol.

[0232] Optionally, in some embodiments, the paging frame offset may be determined based on the SSB period. In particular, the SSB period is assumed to be S. In this case, the frame in which the SSB is located is SFN mod S = K, where SFN denotes the frame number of the paging frame, K denotes the index of the frame in which the SSB resides in the SSB period, and mod denotes the operation of the remainder of an integer division. When S is less than (T div N), the paging frame offset is K; or when S is greater than (T div N), the paging frame offset is S-K. Optionally, in some embodiments, if S is equal to (T div N), the paging frame offset may be K. Optionally, in other embodiments, if S is equal to (T div N), the paging frame offset may be S-K.

[0233] Optionally, in some embodiments, the index of the frame in which the SSB is in the period may be the actual index of the SSB.

[0234] Optionally, in some embodiments, the index of the frame in which the SSB is in the period may also be a reordered index of the SSB.

[0235] The actual index is the SSB index in the period. For example, SSB index 0 is 0, SSB index 1 is 1, and SSB index 2 is 2. Even if SSB 0 and SSB 1 are not sent, SSB index 2 is still 2.

[0236] The reordered index is the index of the SSB actually sent by the network device. For example, SSB index 0 is 0, SSB index 1 is 1, SSB index 2 is 2, and SSB index 3 is 3. Assuming SSB 0 and SSB 2 are not sent, SSB index 1 changes to 0, and SSB index 3 changes by 1.

[0237] Optionally, in other embodiments, the paging frame offset may also be determined based on the sync packet set period. In this case, S may indicate a burst period of the synchronization signal.

[0238] Optionally, in other embodiments, the paging frame offset may also be preset or indicated by the network device. For example, the network device may send indication information to the terminal device to indicate the paging frame offset. It should be understood that the paging frame offset may be a positive number, or may be a negative number, or may be 0. The network device may send indication information to the terminal device in a variety of ways that can be identified by the terminal device to indicate the paging frame offset. . For example, an absolute offset value may be specified, or a relative offset value may be specified. In an implementation, the network device may indicate the number of frames by which the paging frame is shifted, or may indicate the number of frames by which the paging frame is shifted to the right (how many frames the paging frame is delayed), or the number of frames by which the paging frame is shifted to the left. (how many frames ahead of the paging frame).

[0239] Optionally, in other embodiments, the paging frame offset may also be determined based on the index of the frame in which the sync packet set resides in the sync packet set period. For example, the frame in which the sync packet set is located is SFN mod S = K, where the value of K is the index of the sync packet set.

[0240] Optionally, in some embodiments, that the terminal device determines the paging frame frame number based on the paging frame offset includes the following: the terminal device may determine the paging frame frame number based on the Discontinuous Reception cycle. DRX), number of paging events in a DRX cycle, terminal device identification information, and paging frame offset. It is understood that the offset of the paging frame is relative and may be offset to the left, or may be offset to the right, or may not be offset. In particular, the paging frame offset may be a positive number, a negative number, or 0.

[0241] Optionally, in some embodiments, the terminal device determines the frame number for the paging frame based on the following formula:

SFN mod T = (T div N)*(UE_ID mod N) + offset Formula 1.3

where SFN denotes a frame number for a paging frame, T denotes DRX, N = min(T, nB), nB denotes the number of paging events in a DRX cycle, div denotes a division operation, min denotes a min value operation, UE_ID denotes information identification of the terminal device, mod denotes the integer division remainder operation, and offset denotes the offset of the paging frame.

[0242] Additionally, in some embodiments, the paging frame offset can be understood as an offset of the paging frame to be determined relative to the SFN reference frame_ref search call. Bias between the paging reference frame SFNref and the paging frame SFN to be determined may be a left offset of one or more frames, or may be a right offset of one or more frames, or there may be no offset. Specifically, the offset value may be a positive integer, or may be a negative integer, or equal to 0. As can be seen, the frame number of the SFN reference frame_ref paging and the SFN frame number to be determined satisfy the following expression: SFN_ref = SFN + Offset or SFN_ref = SFN - Offset or SFN_ref = SFN.

[0243] For example, the terminal device determines the frame number for the paging frame based on the following formula:

[0244] In another example, the terminal device determines the paging frame frame number SFN, where the paging frame frame number SFN satisfies the following expression:

(SFN + offset) mod T = (T div N)*(UE_ID mod N).

[0245] For another example, if the paging frame offset is 0, the terminal device determines the paging frame frame number SFN, where the paging frame frame number SFN satisfies the following expression:

SFN mod T = (T div N)*(UE_ID mod N), where

offset denotes the paging frame offset, SFN denotes the frame number for the paging frame, T denotes a DRX cycle, N = min(T, nB), nB denotes the number of paging events in a DRX cycle, div denotes a division operation, min denotes a division operation setting the minimum value, UE_ID denotes terminal device identification information, mod denotes an integer division remainder operation, and N denotes the number of paging frames in a DRX cycle.

[0246] It should be understood that Formula 1.4 is to determine the frame number for a paging frame based on the frame number (SFN) of the paging start frame and the paging frame offset. Therefore, the frame number for the paging frame can be determined based on the frame number of the starting paging frame and the offset of the paging frame. It will be understood that, alternatively, the frame number for the paging frame may be determined based on the frame number of the initial paging frame minus the paging frame offset. Whether to add or subtract the paging frame offset depends on whether the paging frame offset is positive or negative. It can be understood that, the paging reference frame frame number SFN _ref satisfies the following expression: SFN _ref mod T = (T div N)* *(UE_ID mod N). The paging frame offset may be a relative value or an absolute value sent by the network device. For example, if the network device sends a relative offset value, where the offset is a negative number (eg, -1), (SFN - offset) in formula 1.4 is actually SFN+1 or SFN plus the absolute paging frame offset value. Therefore, a variant of formula 1.4 could be: (SFN + offset) mod T = (T div N)*(UE_ID mod N). In this case, the network device can send an absolute offset value. Regardless of addition or subtraction, the frame number for the paging frame can be considered to be determined based on the frame number of the paging reference frame, where the frame number of the paging reference frame is determined based on the frame number of the start paging frame plus or minus the paging frame offset.

[0247] Optionally, in other embodiments, the terminal device may further calculate the frame number SFN 1 of the initial paging frame using a method for calculating the frame number for the paging frame in the LTE system, and then add the paging frame offset to SFN 1 to obtain the number frame for the paging frame.

[0248] Optionally, when the offset value is configured by the base station, the offset value may be a positive integer, or may be a negative integer, or may be 0.

[0249] The offset value may be determined based on the SSB period and/or position, or may be determined based on the SMTC period. For example, if the SSB period is T, the offset value can be 0 to T-1, or -T+1 to 0, or -T/2+1 to T/2-1, or -T/2 to T/2 or -T/2-1 to T/2+1. For example, if the SSB period is 5 ms or 10 ms, the offset 0ffset may be 0. For example, if the SSB period is 20 ms, the offset may be 0 or 1 or more, or one or more of -1 and 0 or more, or may be any one or more of -1, 0, and 1. For example, if the SSB period is 40ms, the offset may be any one or more of 0, 1, 2, and 3, or any one or more of -3, - 2, -1, and 0, or may be any one or more of -2, -1, 0, 1, and 2, or may be any one or more of -1, 0, and 1. For example, if the SSB period is 80ms , the offset can be any one or more of 0, 1, 2, 3, 4, 5, 6, and 7 or any one or more of -7, -6, -5, -4, -3, -2, -1 and 0, or can be any one or more of -4, -3, -2, -1, 0, 1, 2, 3, and 4, or can be one or more of -3, -2, -1, 0 , 1, 2, and 3. For example, if the SSB period is 80ms, the offset can be any one or more of 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, and 15, or any one or more of -15, -14, -13, -12, -11 , -10, -9, -8, -7, -6, -5, -4, -3, -2, -1 and 0 or can be any one or more of -7, -6, -5, - 4, -3, -2, -1, 0, 1, 2, 3, 4, 5, 6, and 7, or can be any one or more of -8, -7, -6, -5, -4, -3, -2, -1, 0, 1, 2, 3, 4, 5, 6 7 and 8. For example, when T is less than or equal to 10ms, the offset value is 0.

[0250] The offset value may be determined based on the period and/or position of the SMTC (SS Block Based RRM Measurement Timing Configuration). For example, if the SMTC period is T, the offset value can be 0 to T-1, or -T+1 to 0, or -T/2+1 to T/2-1, or -T/2 to T/2 or -T/2-1 to T/2+1. For example, if the SMTC period is 5ms or 10ms, the offset 0ffset may be 0. For example, if the SMTC period is 20ms, the offset may be 0 or 1 or more, or one or more of -1 and 0 or more , or can be any one or more of -1, 0, and 1. For example, if the SMTC period is 40ms, the offset can be any one or more of 0, 1, 2, and 3, or any one or more of -3, -2, -1, and 0, or may be any one or more of -2, -1, 0, 1, and 2, or may be any one or more of -1, 0, and 1. For example, if the SMTC period is 80 ms, the offset can be any one or more of 0, 1, 2, 3, 4, 5, 6, and 7, or any one or more of -7, -6, -5, -4, -3, -2, - 1 and 0, or may be any one or more of -4, -3, -2, -1, 0, 1, 2, 3, and 4, or may be one or more of -3, -2, -1, 0, 1, 2, and 3. For example, if the SMTC period is 80 ms, the offset can be any one or more kimi of 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14 and 15, or any one or more of -15, -14, -13, - 12, -11, -10, -9, -8, -7, -6, -5, -4, -3, -2, -1 and 0, or can be any one or more of -7, -6, -5, -4, -3, -2, -1, 0, 1, 2, 3, 4, 5, 6, and 7, or can be any one or more of -8, -7, -6, -5 , -4, -3, -2, -1, 0, 1, 2, 3, 4, 5, 6, 7, and 8. For example, when T is less than or equal to 10 ms, the offset value is 0. The network device can also indicate or configure that the position of the PF is offset based on the period or position of the SMTC or SSB.

[0251] The network device may configure N offset values, where each offset value may correspond to one PO, or each offset corresponds to one paging frame. N values can be some or all of the values of 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21 , 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, and 32. The value of N can be configured based on the number of POs or the number of PFs in an SSB period or an SMTC period. For example, if the SSB period includes only one PO or PF, the offset value may be 1 or not configured. For example, if the SSB or SMTC period includes only two POs or PFs, the offset value may be 1 or 2, or not configured. For example, if the SSB or SMTC period only includes three POs or PFs, the offset value may be 1, 2, or 3, or not configured. For example, if the SSB or SMTC period only includes four POs or PFs, the offset value may be 1 or 2 or 3 or 4, or not configured. For example, if the SSB or SMTC period only includes five POs or PFs, the offset value may be 1 or 2 or 3 or 4 or 5 or not configured. For example, if the SSB or SMTC period only includes six POs or PFs, the offset value may be 1 or 2 or 3 or 4 or 5 or 6, or not configured. For example, if the SSB or SMTC period only includes seven POs or PFs, the offset value may be 1 or 2 or 3 or 4 or 5 or 6 or 7 or not configured. For example, if the SSB or SMTC period only includes eight POs or PFs, the offset value may be 1 or 2 or 3 or 4 or 5 or 6 or 7 or 8 or not configured. For example, if the SSB or SMTC period only includes nine POs or PFs, the offset value may be 1 or 2 or 3 or 4 or 5 or 6 or 7 or 8 or 9 or not configured. For example, if the SSB or SMTC period only includes 10 POs or PFs, the offset value may be 1 or 2 or 3 or 4 or 5 or 6 or 7 or 8 or 9 or 10, or not configured. For example, if the SSB or SMTC period only includes 11 POs or PFs, the offset value may be 1 or 2 or 3 or 4 or 5 or 6 or 7 or 8 or 9 or 10 or 11, or not configured. For example, if the SSB or SMTC period only includes 15 POs or PFs, the offset value can be 1 or 2 or 3 or 4 or 5 or 6 or 7 or 8 or 9 or 10 or 11 or 12 or 13 or 14 or 15 or not configured. For example, if the SSB or SMTC period includes only 16 POs or PFs, the offset value can be 1 or 2 or 3 or 4 or 5 or 6 or 7 or 8 or 9 or 10 or 11 or 12 or 13 or 14 or 15 or 16 or not configured. The configured number can be the same as the number of PO or PF in the SSB or SMTC period.

[0252] Alternatively, the offset value may be configured based on the maximum values of the SSB and SMTC periods. For example, in the configuration method, the values that can be configured for the offset are {0, 1, 2, 3, ..., max (T1, T2)-1}, where T1 denotes an SSB period and T2 denotes an SMTC period. Blocks T1 and T2 may be frames. For example, when the SSB period is 20 ms and the SMTC period is 40 ms, the values that can be configured are {0, 1, 2, 3}.

[0253] FIG. 3 is a schematic diagram of a paging frame offset according to an embodiment of the present application. As shown in FIG. 3, when there is no paging frame offset, the frame numbers in which paging frame 1, paging frame 2, and paging frame 3 are located are 0, 4, and 10, respectively. The frame numbers of frames in which SS frame 1 and SS frame 2 are located are 3 and 7, respectively. According to the above method, it can be determined that the paging frame offset is 3. In this case, the frame numbers of frames in which paging frame 1, paging frame 2, and paging frame 3 are located are updated to 3, 7, and 13, respectively. In this case, paging frame 1 is time division multiplexed with a 1 SS frame, and paging frame 2 is time division multiplexed with a 2 SS frame.

[0254] FIG. 4 is a schematic diagram of another paging frame offset according to an embodiment of the present application. As shown in FIG. 4, when there is no paging frame offset, the frame numbers in which paging frame 1, paging frame 2, paging frame 3, paging frame 4, and paging frame 5 are located are 0, 2, 4, 6, and 8 respectively. The frame numbers of frames in which SS frames are located are 3 and 7, respectively. According to the above method, it can be determined that the paging frame offset is 1. In this case, the frame numbers of frames in which paging frame 1, paging frame 2, paging frame 3, paging frame 4, and paging frame 5 are located, are updated to 1, 3, 5, 7, and 9 respectively. Paging frame 2 is time division multiplexed with a 1 SS frame, and paging frame 4 is time division multiplexed with a 2 SS frame.

[0255] FIG. 5 is a schematic diagram of another paging frame offset according to an embodiment of the present application. As shown in FIG. 5, when there is no paging frame offset, the frame numbers in which paging frame 1, paging frame 2, and paging frame 3 are located are 0, 4, and 8, respectively. The frame numbers of frames in which SS frames are located are 1, 3, 5, 7, 9, and 11, respectively. According to the above method, it can be determined that the paging frame offset is 1. In this case, the frame numbers of frames in which paging frame 1, paging frame 2, and paging frame 3 are located are 1, 5, and 9, respectively. Paging frame 2 is time division multiplexed with a 1 SS frame, paging frame 2 is time division multiplexed with a 3 SS frame, and paging frame 3 is time division multiplexed with a 5 SS frame.

[0256] Because the paging frame and the SS frame are multiplexed, the paging message can be time division multiplexed with SSB. This can save time-domain resources so that the saved time-domain resources can be used to send other messages.

[0257] When frequency division multiplexing is performed on a plurality of POs (or a DCI of a plurality of POs), the plurality of POs may be POs on which frequency division multiplexing is performed on a plurality of paging frames. When frequency division multiplexing is performed on a PO in a plurality of frames, or frequency division multiplexing is performed on a PO in a plurality of frames and SSB, one paging frame may include a plurality of POs, or one paging frame includes one PO. When one paging frame includes a plurality of POs, frequency division multiplexing is performed on POs N_FDD and SSB. When the value of N_FDD less than the number of POs in one frame, frequency division multiplexing can be directly performed for PO N_FDD and SSB; or when the value of N_FDD exceeds the number of POs in one frame, frequency division multiplexing may first be performed on the POs in each of the plurality of paging frames, and then the frequency division multiplexing is performed on the POs in the plurality of paging frames. In other words, multiple paging frames may be combined into one paging frame, and then some or all of the paging frames are shifted into an SSB frame. When one paging frame includes one PO, frequency division multiplexing may be performed for a plurality of POs in a plurality of paging frames such that a plurality of POs are located in one paging frame. The frequency division multiplexing may continue to be performed on multiple POs with SSB. In this case, you need to configure quantity K_PO PO in one paging frame. The network device may configure the number of paging frames in the frequency division multiplexing, or may configure the number of paging frames in the SSB frequency division multiplexing, or may further configure the number of POs in the SSB frequency division multiplexing, or may configure the number of POs in one paging frame. call. In this case, N in formula 1.3 and formula 1.4 denotes the number of paging frames and nB/K_PO can be used to calculate the number of paging frames.

[0258] Finally, an integer division by 1024 remainder operation or an integer division by 2048 remainder operation may be performed on the value of the SFN number of the paging message system frame number, which is calculated based on the UE ID, and the system frame number obtained by the integer remainder operation division is the frame number of the frame in which the paging message with the UE ID is located. For example, the integer division remainder operation method is: ((SFN +/- offset) mod T) mod 1024 = (T div N)*(UE_ID mod N). For example, the integer division remainder operation method is SFN 2 mod 1024 = SFN 3, where SFN 2 = SFN 1 + offset, SFN 2 is SFN 1 + offset, and SFN 1 is the frame number of the paging start frame, which is computed from using a method for calculating a frame number for a paging frame in an LTE system.

[0259] Optionally, in some embodiments, the paging target resource includes monitoring window position information, where the monitoring window position information includes the start position of the monitoring target window corresponding to the terminal device in the Q monitoring windows, where one paging event includes Q monitoring windows; and that the terminal device determines the paging target resource includes the following: the terminal device determines the start position of the target monitoring window based on the offset of the monitoring window.

[0260] Optionally, in some embodiments, Q is a positive integer greater than or equal to 2.

[0261] Optionally, in other embodiments, Q is a positive integer less than or equal to 2.

[0262] Optionally, in some embodiments, the duration of each of the Q monitoring windows is the same.

[0263] Optionally, in some embodiments, the monitoring window offset may be determined based on the monitoring window index. At least two monitor windows whose indexes are different correspond to different monitor window offsets.

[0264] One paging frame includes 10 slots, where slots 0 to 4 are slots used for downlink transmission and slots 5-9 are slots used for uplink transmission. The monitoring window starts at slot 2 and the value of Q is 4. Each monitoring window is one slot long. Thus, the first three monitor windows may be located in slots 2-4, respectively, and the last monitor window should be offset by five slots until the next paging frame. In other words, the monitor window offsets of the first three monitor windows are 0, and the monitor window offset of the last monitor window is 5.

[0265] Optionally, in some embodiments, the time domain resources in the monitoring window are sequential.

[0266] Optionally, in some embodiments, the number of time domain resources in the monitoring window may be configured and may be some or all of 0.5 slots, one slot, two slots, and four slots. The paging message refers to SSB frequency division multiplexing. For example, in frequency division multiplexing, the number may be 0.5 slots.

[0267] When the paging message monitoring windows overlap, the management information of a plurality of paging messages sent in the same paging message discovery window may correspond to different SSBs.

[0268] Paging message monitoring windows may overlap. Specifically, one monitor window is associated with k _monitor SSB, where the coefficient k _monitor can be configured, and the value can be any value from 1, 2, 3, 4, 5, 6, 7 and 8.

[0269] When a plurality of paging messages are sent in one slot, it may be predetermined that the paging message control information in the paging message discovery window may be sent in time sequence or may be sent in frequency sequence.

[0270] For example, the protocol may dictate or indicate by the network device that the control information of the first paging message is sent on the first symbol in the slot, and the control information of the second paging message is sent on the second symbol in the slot.

[0271] Alternatively, the protocol may dictate or indicate by the network device that the control information of the first paging message is sent on the second symbol in the slot, and the control information of the second paging message is sent on the third symbol in the slot.

[0272] Alternatively, the protocol may dictate or indicate by the network device that the control information of the first paging message is sent on the first symbol in the slot, and the control information of the second paging message is sent on the third symbol in the slot.

[0273] Alternatively, the protocol may mandate or indicate by the network device that the control information of the first paging message is sent on the first character in the slot, the control information of the second paging message is sent on the second character in the slot, and the control information of the third fragment of the paging message sent on the third character in the slot.

[0274] Alternatively, it may be prescribed in the protocol or indicated by the network device that the control information of the first paging message is sent on the first or second symbol in the slot, and the control information of the second paging message is sent on the third symbol in the slot.

[0275] Alternatively, it may be prescribed in the protocol or indicated by the network device that the control information of the first paging message is sent on the first symbol in the slot, and the control information of the second paging message is sent on the second or third symbol in the slot.

[0276] Alternatively, it may be prescribed in the protocol or indicated by the network device that the control information of the first paging message is sent on the first symbol in the slot, and the control information of the second paging message is sent on the seventh symbol in the slot.

[0277] The network device sends paging messages using different beams in different monitoring windows. In the target monitoring window, the paging message is sent using the beam in which the terminal device is located.

[0278] Optionally, in some embodiments, for the terminal device to determine the initial position of the target monitoring window based on the offset of the monitoring window includes the following: the terminal device determines the initial position of the target monitoring window based on the following formula:

where M _d denotes the start position of the target monitoring window, I denotes the start time of the time domain resource on which the paging event is located, window offset denotes the offset of the monitor window, x denotes the duration of each of the Q monitor windows or the time interval between the start time of each monitor window and by the start time of the next monitoring window, the SSB indicates at least one of the following types of information: a time index of a target synchronization signal block having an association with the monitoring target window, a time index of a possible synchronization signal block having an association with the monitoring target window, and an index of the target monitoring window , w denotes the number of sync blocks associated with the monitoring target window, and floor denotes the round down operation. The monitoring window offset may be a time offset of the first of the Q monitoring windows relative to the reference position. Alternatively, the monitoring window offset may be the sum of the fixed time offset and the time offset of the first of the Q monitoring windows relative to the reference position. The fixed time offset may be determined based on information configured by the network device. Since a fixed time offset is used, monitoring windows can be relatively centralized to facilitate discovery by the terminal device.

[0279] Optionally, in some embodiments, the monitoring window offset is associated with the SSB offset.

[0280] Optionally, in some embodiments, the monitoring target window is associated with one or more synchronization signal blocks.

[0281] The relation of communication can be any of relations, such as relation of quasi-location (Quasi-Co-Location, QCL), relation of presence of the same beam and relation of presence of the same antenna port.

[0282] Optionally, in some embodiments, if the value of w is 1, the variants of formula 1.5 may be the following formulas:

[0283] Iwindow offset denotes the starting position of the PO. Iwindow offset may include two parts: for example, Iwindow offset = Iwindow offset 1 + Iwindow offset 2, where the first part of Iwindow offset 1 may be the time domain position or PDCCH slot position of the paging message corresponding to SS/PBCH block index 0 or Iwindow offset 1 is a starting position in the PDCCH time domain of the paging message corresponding to index i-1 of the SS/PBCH block. The second part of Iwindow offset 2 may include an offset of the time domain positions or PDCCH slot positions of the paging messages corresponding to different SSB indices relative to the SSB positions, or is the number of uplink slots between the PDCCH start time domain position of the paging message corresponding to index i-1 of the SS/PBCH block and a start position in the PDCCH time domain of the paging message corresponding to index i of the SS/PBCH block, or the number of slots that cannot be used to transmit the paging message. The offset may be caused by an SSB index or may be caused by an uplink/downlink collision. For example, the way Iwindow offset 2 is determined is K_DU,P * N_UP,T, where K_DU,P is the number of slots between the PO start position and the slot or time domain resource of the paging message corresponding to SS/PBCH block index i, N_UP,T is the number of slots uplink in the downlink to uplink switching point periodicity, calculation method K_DU,Pis floor(floor(x*i)/N_{P slot},_T), N_UP,T-the number of uplink slots in the downlink to uplink switch point periodicity, or the number of slots that cannot be used to send a paging message, and N_{P slot},_T is the number of downlink and/or flex slots in the downlink to uplink switch point periodicity or the number of slots that can be used to send a paging message.

[0284] In formula 1.6, the meaning of each term is the same as in formula 1.5. Details are not described here again.

-ом кадре поискового вызова, где Q_max обозначает максимальное количество окон мониторинга, включенных в кадр поискового вызова, и

обозначает операцию округления. [0285] Optionally, in some embodiments, before the terminal device determines the initial position of the target monitoring window based on the offset of the monitoring window, the method further includes: the terminal device determines that the target monitoring window is in

-th paging frame, where Q _max denotes the maximum number of monitor windows included in the paging frame, and

denotes the rounding operation.

[0286] Optionally, in some embodiments, Q _max is determined based on at least one of the duration of each of the monitoring windows Q, the number of synchronization signal blocks, the number of paging messages, and the subcarrier spacing.

[0287] Optionally, in other embodiments, Q _max is a preset value.

[0288] Optionally, in other embodiments, Q _max is determined based on an indication of the network device.

[0289] Optionally, in some embodiments, the time domain resources occupied by the Q monitoring windows are sequential time domain resources or non-consecutive time domain resources. The non-sequential time domain resources belong to the sequential time domain resource segment, and other time domain resources other than the time domain resources occupied by the Q monitoring windows have been defined in the serial time domain resource segment to convey information other than the paging message.

[0290] Optionally, in some embodiments, the time domain position of each monitoring window may be the same as the position of the SSB slot associated with the monitoring window. The duration of each monitoring window is the same. The duration block of each monitoring window may be a slot.

[0291] Optionally, in some embodiments, the paging message identification information in at least any two of the N paging events is different, where the identification information can be Paging-Radio Network Temporary Identifier (P-RNTI) or random access preambles.

[0292] Optionally, in some embodiments, when a plurality of P-RNTIs exist, the plurality of P-RNTIs may be used to distinguish between paging messages of different POs, or used to distinguish between paging messages of different groups of terminal devices. The number of P-RNTIs may be any numeric value from 2, 4, 8, 16, 32, and 64. The terminal device or network device may select the number of P-RNTIs based on at least one of a random access channel event period, a frame duration, and sync burst period during a DRX cycle. The number of P-RNTIs may also be configured by the network device.

[0293] When P-RNTIs are used to distinguish between different POs, the P-RNTIs may be associated with PO indices. Specifically, the P-RNTI PO whose index is i is P-RNTI0+i, where P-RNTI0 denotes the initial P-RNTI and i denotes the PO index. For example, if P-RNTI PO 0 is P-RNTI0, then P-RNTI PO 1 is P-RNTI0+1, P-RNTI PO 2 is P-RNTI0+2, and P-RNTI PO 3 is P -RNTI0+3. The first PO (ie, the PO whose index is 0) may be a PO in a system frame, or may be the first PO in a frequency division multiplexing. When the terminal device detects the DCI of different POs, the P-RNTI values may be used to distinguish between different POs. When P-RNTIs are used to distinguish between different SSBs, P-RNTIs can be associated with SSBs. Similarly, the P-RNTI SSB whose index is i is P-RNTI0+i, where P-RNTI0 denotes the initial P-RNTI and i denotes the SSB index. For example, if P-RNTI SSB 0 is P-RNTI0, then P-RNTI SSB 1 is P-RNTI0+1, P-RNTI SSB 2 is P-RNTI0+2, and P-RNTI SSB 3 is P -RNTI0+3. When the terminal device detects the DCI of different SSBs, the P-RNTI values may be used to distinguish between the different SSBs.

[0294] When a plurality of random access preambles is used to distinguish between different POs, index values and the number of random access preambles used for a paging message may be associated with the PO indexes. For example, a random access preamble for a PO whose index i is from i*N to (i+1)*N-1. For example, the random access preamble for PO 0 is 0 to N-1, the random access preamble for PO 1 is N to 2N-1, the random access preamble for PO 2 is 2N to 3N-1, and the random access preamble for PO 3 is from 3N to 4N-1. Alternatively, the random access preambles of different POs are inconsistent and may be i+K (0 to N-1), where K denotes the number of POs. For example, the random access preamble for PO 0 is 0, K, 2K, ..., K (N-1); the random access preamble for PO 1 is 1, K+1, 2K+1, ..., K (N - 1) +1; the random access preamble for PO 2 is 2, K+2, 2K+2, ..., K (N - 1) +2; and the random access preamble for PO 3 is 3, K+3, 2K+3, ..., K (N-1)+3. By detecting the random access preambles of different POs, the network device can distinguish between information received at different POs. The number of random access preambles used for the paging message may be K*N _preamble where K denotes the number of POs in the Random Access Channel Occasion (RO) period and N _preamble denotes the number of random access preambles used for the message. search call. The N _{preamble value} may be a positive integer greater than or equal to 1. When the N _{preamble value} is a positive integer greater than 1, the N _{preamble value} may be associated with a group of terminal devices. The number of the plurality of random access preambles may be a multiple of the number of random access preambles used for paging in the RO. For example, a multiple of any of 2, 4, 8, 16, 32, and 64. The network device or terminal device may select the number of random access preambles based on at least one of the following: random access channel event period, frame duration, dialing period sync packets per DRX cycle, number of SSBs, random access preamble format, random access preamble length, random access carrier frequency, random access preamble bandwidth, number of ROs per slot, number of downlink signals per random access resource per slot, number of corresponding random access response messages in the slot, number of paging events in a DRX cycle, number of random access preambles in RO, number of ROs associated with the downlink signal, total number of random access preambles or resources associated with the downlink signal, the number of actually from forwarded downlink signals, RO duration, subcarrier spacing, bandwidth, frame structure, type of service, random access preamble start time, random access preamble duration, random access preamble end time, time domain position information of the random access response window corresponding to random access preamble, frequency domain position information of the random access response window corresponding to the random access preamble, random access preamble index, paging message index, paging user group index corresponding to the random access preamble, time-frequency resource index corresponding to the random access preamble access, synchronization signal block index corresponding to the random access preamble, total number of paging messages, total number of random access channel events, number of field groups paging users, the number of paging messages, the number of random access preambles associated with the paging message, the number of POs, and the length of the DRX cycle. The quantity may be configured by the network device, or not configured, but obtained by calculation based on the associated parameters. For example, the number is calculated based on the number of POs in a DRX cycle or a random access channel event period together.

[0295] Optionally, in some embodiments, before the terminal device receives a paging target message on the paging target resource, the method further includes: the terminal device receives a paging indication sent by the network device, where the paging indication is used to indicate that the network device will send the target paging message.

[0296] The network device may send a system update indication, an ETWS indication, and a CMAS indication along with the paging indication. The system update indication may include one bit used to indicate whether the system information is changing. When the terminal device receives the system update indication, the terminal device determines, based on the contents of the system update indication, whether the system information needs to be updated. The system update indication may also be a plurality of bits, and the system update indication of the plurality of bits is used to indicate what type of system information is updated. For example, 00100 indicates that the system information block 3 has been updated.

[0297] Optionally, in some embodiments, the method further includes: the terminal device receives the time domain block indication information sent by the network device, where the time domain block indication information is used to indicate the number of time domain blocks included in the frame search call.

[0298] Optionally, in some embodiments, the time domain block indication information may include subcarrier spacing. Thus, the terminal device can determine, based on the subcarrier spacing, the number of time domain blocks included in the paging frame.

[0299] For example, subcarrier spacing may be configured on the PBCH and may be configured using the SSB index and half frame indication. For example, in the case of low frequency (below 6 GHz), one bit in the SSB index may be used to indicate whether 15 kHz or 30 kHz subcarrier spacing; or, in the case of high frequency (above 6 GHz), the half-frame indication may be used to indicate whether the sub-carrier spacing is 60 kHz or 120 kHz.

[0300] Optionally, in other embodiments, the time domain block indication information may be the number of time domain blocks included in the paging frame.

[0301] FIG. 6 is a schematic flowchart of another method for transmitting a paging message according to an embodiment of the present application.

[0302] 601. The network device defines a paging resource, where the paging resource includes at least one of the following types of information: paging event position information N, paging frame position information, and monitoring window position information.

[0303] 602. The network device sends a paging message on the paging resource to the terminal device.

[0304] Optionally, in some embodiments, the paging resource includes location information of N paging events, and N paging events are located on M time domain resources, where N is a positive integer greater than or equal to 1, M is positive an integer greater than or equal to 1 and less than or equal to N, and the position of each of the M time domain resources in the paging frame is associated with at least one of the subcarrier spacing, the time domain position of the synchronization signal block actually sent by the network device, and the position in time region of a possible block of the synchronization signal.

[0307] The specific implementation in which the network device determines the position of each of the M time domain resources in the paging frame based on the value of M is similar to the specific implementation in which the terminal device determines the position of each of the M time domain resources in the paging frame based on the value M. The difference is that the terminal device only needs to determine the time domain position or start position of the time domain resource where the paging target event is located in the M time domain resources in the paging frame, but the network device needs to determine the time domain area or the starting position of each of the M time domain resources in the paging frame. For a specific implementation in which the network device determines the time domain position and start position of each time domain resource in a paging frame, refer to the embodiment shown in FIG. 2.

[0310] Optionally, in some embodiments, the paging target resource includes paging frame position information, and the paging frame position information includes a frame number for the paging frame; and that the network device determines the paging target resource includes the following: the network device determines the frame number for the paging frame based on the offset of the paging frame. The specific implementation in which the network device determines the paging frame frame number based on the paging frame offset is the same as the specific implementation in which the terminal device determines the paging frame frame number based on the paging frame offset. Details are not described here again.

[0311] Optionally, in some embodiments, the paging frame offset is associated with at least one of the following: a sync block period, a time domain position of a sync block actually sent by the network device, and a time domain position of a possible sync block .

[0312] Likewise, the paging frame offset is determined based on the synchronization signal block period.

[0313] Similarly, the network device may determine the frame number for the paging frame based on the DRX discontinuous reception cycle, the number of paging events included in the DRX cycle, the terminal device identification information, and the paging frame offset.

[0314] Optionally, in some embodiments, the paging resource includes monitoring window position information, and the monitoring window position information includes a start position of each of Q monitoring windows, where one paging event includes Q monitoring windows, and Q is a positive integer greater than or equal to 1; and that the network device determines the paging target resource includes the following: the network device determines the start position of each of the Q monitoring windows based on the monitoring window offset.

[0315] The specific implementation in which the network device determines the initial position of the monitoring window based on the offset of the monitoring window is similar to the specific implementation in which the terminal device determines the initial position of the target monitoring window based on the offset of the monitoring window. The difference is that the terminal device only needs to determine the start position of the target monitoring window, but the network device needs to determine the start position of each monitoring window. Details are not described here again.

-ом кадре поискового вызова, где Q_max обозначает максимальное количество окон мониторинга, включенных в кадр поискового вызова,

обозначает операцию округления и q=1, …, Q.[0316] Similarly, before the network device determines the initial position of the monitoring window based on the offset of the monitoring window, the method further includes: the network device determines that the q-th monitoring window in the Q monitoring windows is located at

-th paging frame, where Q _max denotes the maximum number of monitoring windows included in the paging frame,

denotes the rounding operation and q=1, …, Q.

[0317] Similarly, Q _max is determined based on at least one of the duration of each of the Q monitoring windows, the number of synchronization signal blocks, the number of paging messages, and the subcarrier spacing; or Q _max is a preset value.

[0318] Optionally, in some embodiments, the network device may also indicate Q _max to the terminal device such that the terminal device determines the position of the target monitoring window based on Q _max .

[0319] Similarly, the time domain resources occupied by the Q monitoring windows are sequential time domain resources or non-consecutive time domain resources. The non-sequential time domain resources belong to the sequential time domain resource segment, and other time domain resources other than the time domain resources occupied by the Q monitoring windows have been defined in the serial time domain resource segment to convey information other than the paging message.

[0320] The network device may use different beams in different monitoring windows in the Q monitoring windows to send paging messages to terminal devices in the beams. For example, assuming Q is 3, the network device may use beam 1 in the first monitoring window to send a paging message to a terminal device in range of beam 1; the network device may use beam 2 in the second monitoring window to send a paging message to a terminal device in range of beam 2; and the network device may use beam 3 in the third monitoring window to send a paging message to the terminal device in range of beam 3.
