Description

Technical Field

[0001] This application relates to the field of communication technologies, and in particular, to a method, apparatus, and storage medium for determining a paging occasion. Background Art

[0002] A paging message is initiated by the network side. A user equipment (UE) in the idle state receives the paging message and then initiates a random access process. The paging process includes paging, a 4-step random access process, and subsequent information exchange with the radio resource control (RRC) layer on the serving link. During each discontinuous reception (DRX) cycle, the UE needs to listen for a paging occasion (PO) to receive the paging message. A PO can include multiple time slots for transmitting downlink control information (DCI).

[0003] In traditional technologies, in a beam-hopping satellite system, the network side notifies the UE of paging resource configuration parameters through system information. If the UE receives the paging message by multiplexing the default resource configuration corresponding to the control channel of the first type of system information block (SIB1), since the UE does not know the specific location where the network side sends the paging message, the UE will start listening for the paging message from the first symbol of the SIB1 control channel resource configuration. This results in an invalid listening time for the UE and causes a certain amount of resource waste. Summary of the Invention

In some network architectures, the network device may include a centralized unit (CU) node and a distributed unit (DU) node, and the centralized unit and the distributed unit may also be geographically separated.

[0071] The following describes each embodiment of the present application in detail with reference to the accompanying drawings of the specification. It should be noted that the display order of the embodiments of the present application only represents the sequence of the embodiments, and does not represent the superiority or inferiority of the technical solutions provided by the embodiments.

[0072] In a satellite system, there are wide beams and narrow spot beams (also known as hopping beams). Among them, the wide beam has a larger coverage area. One satellite may include one or more wide beams, constituting the entire satellite coverage area. The coverage area of the narrow spot beam is very small. The coverage area of one narrow spot beam is called a beam position, and there are hundreds of beam positions in one satellite coverage area. The hopping beam serves the entire satellite coverage range in a hopping manner, covering only one beam position at a certain moment and covering another beam position at the next moment.

[0073] The paging occasion determination method provided by the embodiments of the present application can be applied to an application environment as Figure 1 shown. As Figure 1As shown, in a hopping beam satellite system, the beam coverage area of the satellite includes multiple beam positions, such as beam position 1, beam position 2, and beam position 3, etc. The hopping beam sends a synchronization block (Synchronization Signal / PBCH Block, SSB) at each beam position, and sends all SSBs at all beam positions within the beam coverage area. Among them, the even frames (such as SFN0, SFN2, etc.) in the system frame (System Frame, SF) are used to send SSBs and the first type of system information block (System Information Block Type 1, SIB1) corresponding to the SSBs.

[0074] In an exemplary embodiment, as Figure 2 shown, a schematic diagram of a system frame is provided. Taking a 30 kHz subcarrier spacing as an example, as Figure 2 shown, the length of the system frame SFN0 with a frame number of 0 is 10 ms. A system frame includes 10 subframes (i.e., subframe 0 to subframe 9). Among them, a subframe includes 2 time slots, that is, a system frame includes 20 time slots (i.e., time slot 0 to time slot 19). As Figure 2 shown, the first 4 time slots (i.e., time slot 0 to time slot 3) of the system frame SFN0 are used to send SSBs. Two SSBs are sent in each time slot, that is, a total of 8 SSBs are sent in a system frame.

[0075] In the system frame, each SSB corresponds to a beam position. As Figure 2 shown, the two SSBs sent in time slot 0 correspond to beam positions B0 and B1 respectively, the two SSBs sent in time slot 1 correspond to beam positions B2 and B3 respectively, the two SSBs sent in time slot 2 correspond to beam positions B4 and B5 respectively, and the two SSBs sent in time slot 3 correspond to beam positions B6 and B7 respectively.

[0076] In the system frame, each SSB corresponds to a SIB1, and each SIB1 occupies two time slots. Each beam position corresponds to a SIB1 within an SSB period. As Figure 2 shown, SIB1 starts to be sent from time slot 4 (i.e., the 5th time slot). The SIB1 corresponding to each beam position occupies 2 time slots. Since 8 SSBs are sent in a system frame, corresponding to 8 beam positions, 16 time slots are occupied by SIB1 in a system frame. Among them, the time slots for sending SIB1 of adjacent beam positions are arranged continuously. For example, the time slots for sending SIB1 of beam position 0 are time slot 4 and time slot 5, and the time slots for sending SIB1 of beam position 1 are time slot 6 and 7, and the time slots for sending SIB1 of beam position 0 and beam position 1 are arranged continuously.

[0077] It should be noted that when the subcarrier spacing is greater than 30 kHz (for example, 120 kHz), the number of time slots included in a system frame is greater than 20, and the SIB1 of 8 wave positions occupies the last 16 time slots of a system frame.

[0078] After the network side initiates paging, the terminal device in the idle state can receive the paging message and then initiate a random access procedure. Within each DRX cycle, the terminal device needs to listen to a PO to receive the paging message. When part of the resources in a system frame are used to transmit the paging message, this system frame can be called a paging frame (PF).

[0079] The network side broadcasts the paging message on the PO. In a beam-hopping satellite system, there must be a PO in each wave position covered by the satellite, and the POs in different wave positions are different. For the purpose of saving power consumption, the terminal device only listens to the paging message on its own paging occasion PO.

[0080] In the related art, if the configured common paging search space identifier (ID) is equal to 0, then the terminal device receives the paging message on the default resources corresponding to the control channel of SIB1. As Figure 2 shown, the SIB1 control channel resources corresponding to wave position 0 (i.e., wave position B0) start from time slot 4 and occupy two time slots, time slot 4 and time slot 5, and the offset relative to the frame start position is 4. The control channel resources of SIB1 corresponding to wave position 1 (i.e., wave position B1) start from time slot 6 and occupy two time slots, time slot 6 and time slot 7, and the offset relative to the frame start position is 6. At this time, the paging occasion of wave position 0 corresponds to time slot 4 and time slot 5, and the terminal device starts listening from time slot 4. The paging occasion of wave position 1 corresponds to time slot 6 and time slot 7, and the terminal device starts listening from time slot 6; the same applies to the other wave positions.

[0081] At this time, assuming that the network side sends a paging message in time slot 5, then for the terminal device of wave position 0, it will not receive the paging message in time slot 4 and can only receive the paging message in time slot 5. Similarly, assuming that the network side sends a paging message in time slot 7, for the terminal device of wave position 1, it will not receive the paging message in time slot 6 and can only receive the paging message in time slot 7. In this case, since the terminal device does not know the specific location where the paging message is sent, if the network side does not send the PDCCH corresponding to the paging at the start position of the listening time slot of SIB1, and the terminal device listens from the start symbol of the first time slot according to the configuration, then the terminal device will have a period of invalid listening time, resulting in a certain waste of resources.

[0082] In the related art, if the public paging search space identifier configured by the system is not equal to 0, then the system specifies the configuration for the terminal device to receive paging. The system information sent by the network to the terminal device includes parameters such as the paging cycle, the number of paging frames and the offset, the number of paging occasions included in the paging frame, and the start position of the paging occasion. The terminal device can use these parameters to calculate its own paging occasion. The specific parameters are the default paging cycle (defaultPagingCycle), the number of paging frames and the paging frame offset (nAndPagingFrameOffset), and the first PDCCH monitoring occasion of each paging occasion (firstPDCCH-MonitoringOccasionOfPO).

[0083] It can be seen that if the default resources corresponding to the control channel of SIB1 are not reused and the network configures the paging parameters, although the specific position of paging can be indicated, the network needs to configure a set of paging parameters for each wave position. And a satellite beam coverage area will contain hundreds of wave positions, which will cause a greater burden on the network side and increase the system design complexity.

[0084] In the embodiments of the present application, in order to save resources, reduce the power consumption of the terminal device, and at the same time not increase the system design complexity, the terminal device can accurately determine the paging occasion in a certain way, so as to ensure that the terminal device listens to the paging message more accurately. The core of the paging occasion determination method provided in the embodiments of the present application is: when the terminal device reuses the default resources corresponding to the SIB1 control channel to configure the reception of the paging message, the network side instructs the terminal device to calculate the time slot or symbol for itself to listen to the paging through a certain rule, so as to listen to the paging message more accurately. The following details the paging occasion determination method provided in the embodiments of the present application.

[0085] In an exemplary embodiment, as Figure 3 shown, a paging occasion determination method is provided, and this method can be applied to a terminal device in a hopping beam satellite system. As Figure 3 shown, this method may include:

[0086] Step S301, obtain the time slot offset number.

[0087] Among them, the time slot offset number can be used to characterize the time slot offset situation of the paging occasion relative to the start position of the paging frame where it is located. The terminal device can obtain the time slot offset number from the system information sent by the network side, or can obtain the time slot offset number by other means, and the embodiments of the present application do not limit this.

[0088] In one example, when the network configures the paging search space identifier of the terminal device to be 0, the terminal device can obtain the slot offset number from the system information. When the network configures the paging search space of the terminal device to be 0, it indicates that the terminal device will receive the paging message by multiplexing the default resource configuration corresponding to the SIB1 control channel. To accurately determine the paging occasion, the terminal device needs to calculate the starting position of the paging occasion in the paging frame. Since the slot offset number can represent the slot offset of the paging occasion relative to the starting position of the paging frame, the terminal device can obtain the slot offset number, and thus determine the specific starting position of the paging occasion in the paging frame based on the slot offset number.

[0089] Step S302: Obtain the time index value of the synchronization block corresponding to the beam position where the terminal device is located.

[0090] In a hopping beam satellite system (which can be simply referred to as the system), each beam position corresponds to a synchronization block, i.e., an SSB. In the system, each SSB is assigned a time index value to distinguish different SSBs. Suppose there are 256 beam positions, then there are 256 SSBs, and the time index values of these 256 SSBs can be from 0 to 255, and these 256 SSBs can be denoted as SSB0 to SSB255.

[0091] Step S303: Determine the paging frame in which the paging occasion corresponding to the terminal device is located according to the time index value.

[0092] In the system, even frames (such as SFN0, SFN2, etc.) are used to transmit the SSBs corresponding to each beam position. Since the number of SSBs transmitted in one even frame is limited, multiple even frames are required in the system to transmit the SSBs corresponding to all beam positions. In the embodiment of the present application, the system frame used to transmit the SSB corresponding to the beam position where the terminal device is located can be determined according to the time index value of the synchronization block corresponding to the beam position where the terminal device is located, and this system frame is the paging frame in which the paging occasion corresponding to the terminal device is located.

[0093] In some embodiments, step S302 may include: determining the frame number according to the quotient obtained by dividing the time index value by the number of synchronization blocks in each system frame; determining the system frame corresponding to the frame number as the paging frame in which the paging occasion corresponding to the terminal device is located.

[0094] The number of synchronization blocks in each system frame can be pre-configured. Generally, the number of synchronization blocks in each system frame can be 8 (as Figure 2 shown).

[0095] In one example, assume that the SSB corresponding to the wave position where the terminal device is located is SSB0, indicating that the corresponding time index value is 0. The quotient obtained by dividing the time index value 0 by the number 8 of synchronization blocks in each system frame is 0. Therefore, the system frame SFN0 corresponding to frame number 0 can be determined as the paging frame corresponding to the terminal device. Similarly, if the SSB corresponding to the wave position where the terminal device is located is SSB7, then the system frame SFN0 can be determined as the paging frame corresponding to the terminal device; exemplarily, if the index value is 7, and 7 divided by the number 8 is not divisible, then the quotient of 7 divided by 8 is rounded down, which is equal to 0; similarly, if the index value is 13, and 13 divided by the number 8 is not divisible, then the quotient of 13 divided by 8 is rounded down, which is equal to 1; after obtaining the rounded-down value of the quotient, based on the premise that synchronization blocks are transmitted in even frames, the specific system frame corresponding to the terminal device is determined.

[0096] In another example, if the SSB corresponding to the wave position where the terminal device is located is SSB8, indicating that the corresponding time index value is 0, and the quotient obtained by dividing the time index value 8 by the number 8 of synchronization blocks in each system frame is 1. Considering that synchronization blocks are only transmitted in even frames in the system, the system frame SFN2 can be determined as the paging frame corresponding to the terminal device. Similarly, if the SSB corresponding to the wave position where the terminal device is located is SSB255, and the quotient obtained by dividing the time index value 255 by the number 8 of synchronization blocks in each system frame is 31, the system frame SFN62 can be determined as the paging frame corresponding to the terminal device.

[0097] In the embodiment of the present application, the paging frame where the paging occasion corresponding to the synchronization block is located is the same as the system frame for transmitting the synchronization block, which can be expressed as , where i represents the time index value, and SSBi represents the SSB with time index value i.

[0098] Step S304, determine the starting position of the paging occasion corresponding to the terminal device in the paging frame according to the time index value and the time slot offset number.

[0099] Since a paging frame includes multiple time slots, and the paging message of the terminal device is sent in some of these time slots, after determining the paging frame where the paging occasion corresponding to the terminal device is located, it is also necessary to determine the starting position of the paging occasion corresponding to the terminal device in the paging frame.

[0100] In some embodiments, step S304 may include: determining the time slot position according to the remainder obtained by dividing the time index value by the number of synchronization blocks in each system frame and the time slot offset number; and determining the time slot position as the starting position of the paging occasion corresponding to the terminal device in the paging frame.

[0101] In one example, the time slot position can be determined by formula one:

[0102]

[0103] Formula 1

[0104] Among them, a represents the time slot position, n represents the time slot offset number, i represents the time index value, k represents the number of synchronization blocks in a system frame, and mod represents the modulo operation (which can also be called the remainder operation). It should be noted that considering that the first 4 time slots in a system frame (i.e., Figure 2 the time slots 0 to 3 shown) are used to transmit SSB and cannot be used to transmit paging messages, so the minimum value of n is 4.

[0105] In a possible implementation manner, the method may further include: obtaining a symbol offset number. At this time, step S304 may include: determining the symbol position according to the remainder obtained by dividing the time index value by the number of synchronization blocks in each system frame, the time slot offset number, the number of symbols in each time slot, and the symbol offset number; and determining the symbol position as the starting position of the paging occasion corresponding to the terminal device in the paging frame.

[0106] Among them, the symbol offset number can be used to characterize the symbol offset situation of the paging occasion relative to the starting position of the listening time slot of SIB1.

[0107] As Figure 2 shown, the paging occasions corresponding to wave position 0 are the listening time slots time slot 4 and time slot 5. Therefore, the terminal device at wave position 0 starts listening for paging messages from time slot 4. The paging occasions corresponding to wave position 1 are the listening time slots time slot 6 and time slot 7. Therefore, the terminal device at wave position 1 starts listening for paging messages from time slot 6. The same applies to the remaining wave positions. If starting to listen from the starting position of the listening time slot, then the terminal device will have a period of invalid listening time, resulting in a certain waste of resources. In the embodiments of the present application, starting to listen after offsetting a certain number of symbols from the starting position of the listening time slot, thereby saving resources.

[0108] In an example, the symbol position can be determined by Formula 2:

[0109]

[0110] Formula 2

[0111] Among them, b represents the symbol position, n represents the time slot offset number, i represents the time index value, k represents the number of synchronization blocks in each system frame, k can take values such as 8, represents the remainder obtained by dividing the time index value by the number of synchronization blocks in each system frame, h represents the number of symbols in each time slot, h can take values such as 14, and s represents the symbol offset number.

[0112] After determining the paging frame in which the paging occasion corresponding to the terminal device is located and the starting position in the paging frame, the terminal device can, when receiving the paging frame, start listening for paging messages from the starting position.

[0113] In the embodiments of the present application, the starting time slot can be determined only according to the time slot offset number, or the starting symbol can be determined according to the time slot offset number and the symbol offset number. The former is simpler to calculate, and the starting position determined by the latter is more accurate.

[0114] The above paging occasion determination method accurately determines the paging occasion by obtaining the time slot offset number, determining the paging frame in which the paging occasion is located according to the time index value of the synchronization block corresponding to the wave position where the terminal device is located, and determining the starting position of the paging occasion in the paging frame according to the time index value and the time slot offset number, which is beneficial for the terminal device to more accurately listen for paging messages and saves resources.

[0115] In an exemplary embodiment, as Figure 4 shown, a paging occasion determination method is provided. As Figure 4 shown, the method may include:

[0116] Step S401, the network side sends system information to the terminal device.

[0117] Step S402, the terminal device determines the paging occasion according to the system information.

[0118] In some embodiments, step S402 may include: when the network configures the paging search space identifier of the terminal device to be 0, the terminal device obtains the time slot offset number and the symbol offset number from the system information, and then determines the paging occasion according to the obtained situation of the time slot offset number and the symbol offset number.

[0119] In the embodiments of the present application, according to the obtained situation of the time slot offset number and the symbol offset number, it can be divided into three cases. Case 1, the time slot offset number is obtained but the symbol offset number is not obtained. Case 2, the time slot offset number is obtained and the symbol offset number is obtained. Case 3, the time slot offset number is not obtained. The processing methods for the three cases are described below.

[0120] Case 1: If the terminal device obtains the time slot offset number from the system information but does not obtain the symbol offset number, the terminal device can first determine the time slot position according to the remainder obtained by dividing the time index value by the number of synchronization blocks in each system frame and the time slot offset number through formula 1, and then determine the time slot position as the starting position of the paging occasion corresponding to the terminal device in the paging frame.

[0121] Taking Figure 2 as an example, the time slots in which the paging occasions corresponding to the wave positions of each SSB are configured by the system are as follows:

[0122] Assume there are 256 SSBs in total, and the SSB period is 640 ms.

[0123] For all wave positions, the following parameters are the same: Paging period: the same as the SSB period, which is 640 ms; Number of paging frames: 1; Number of paging opportunities included in each paging frame: 1.

[0124] The time slots where the paging opportunities of the wave positions corresponding to each SSB are located are different. Taking n = 4 as an example, the time slot positions where the paging opportunities of each wave position are located are calculated through Formula 1 as follows:

[0125] The synchronization block corresponding to the terminal device is SSB0, the paging frame is SFN0, and the time slot position is time slot 5;

[0126] The synchronization block corresponding to the terminal device is SSB1, the paging frame is SFN0, and the time slot position is time slot 7;

[0127] ……

[0128] The synchronization block corresponding to the terminal device is SSB7, the paging frame is SFN0, and the time slot position is time slot 19;

[0129] The synchronization block corresponding to the terminal device is SSB8, the paging frame is SFN2, and the time slot position is time slot 5;

[0130] ……

[0131] The synchronization block corresponding to the terminal device is SSB255, the paging frame is SFN62, and the time slot position is time slot 19.

[0132] Case 2: If the terminal device obtains the time slot offset number and the symbol offset number from the system information, the terminal device can first determine the symbol position through Formula 2 according to the remainder obtained by dividing the time index value by the number of synchronization blocks in each system frame, the time slot offset number, the number of symbols in each time slot, and the symbol offset number, and then determine the symbol position as the starting position of the paging opportunity corresponding to the terminal device in the paging frame.

[0133] Take Figure 2 as an example, the symbols where the paging opportunities configured by the system for the wave positions corresponding to each SSB are located are as follows:

[0134] Assume there are 256 SSBs in total, and the SSB period is 640 ms.

[0135] For all wave positions, the following parameters are the same: Paging period: the same as the SSB period, which is 640 ms; Number of paging frames: 1; Number of paging opportunities included in each paging frame: 1.

[0136] The paging occasions of the wave positions corresponding to each SSB are in different time slots. Taking n = 4 and s = 14 as an example, the symbol positions of the paging occasions of each wave position are calculated by Formula 2 as follows:

[0137] The synchronization block corresponding to the terminal device is SSB0, the paging frame is SFN0, and the symbol position is symbol 70;

[0138] The synchronization block corresponding to the terminal device is SSB1, the paging frame is SFN0, and the symbol position is symbol 98;

[0139] ……

[0140] The synchronization block corresponding to the terminal device is SSB7, the paging frame is SFN0, and the symbol position is symbol 266;

[0141] The synchronization block corresponding to the terminal device is SSB8, the paging frame is SFN2, and the symbol position is symbol 70;

[0142] ……

[0143] The synchronization block corresponding to the terminal device is SSB255, the paging frame is SFN62, and the symbol position is symbol 266.

[0144] Case 3: If the terminal device fails to obtain the time slot offset number from the system information, the terminal device determines the start position of the listening time slot of SIB1 corresponding to the wave position of the terminal device in the paging frame as the start position of the paging occasion corresponding to the terminal device in the paging frame.

[0145] As Figure 2 shown, the paging occasion of wave position 0 corresponds to time slots 4 and 5, and the terminal device starts listening from time slot 4. The paging occasion of wave position 1 corresponds to time slots 6 and 7, and the terminal device starts listening from time slot 6. The same applies to the other wave positions.

[0146] In the embodiments of the present application, when the terminal device multiplexes the default resource configuration corresponding to the SIB1 control channel to receive the paging message, the network side can indicate the parameters (time slot offset number, or time slot offset number and symbol offset number) required to determine the paging occasion to the terminal device. Thereafter, the terminal device can calculate the time slot or symbol for listening to the paging message according to certain rules.

[0147] In the embodiments of the present application, there is a one-to-one correspondence between the SSB and the PDCCH monitoring occasion for paging. For the situation where the terminal device in the beam-hopping satellite system cannot accurately monitor the paging message, the paging occasion determination method provided by the embodiments of the present application enables the terminal device to calculate the time slot or symbol where the paging monitoring occasion corresponding to each SSB is located according to the time slot offset number and symbol offset number notified by the network side through the system information. Without increasing the system calculation complexity, it is beneficial for the terminal device to more accurately monitor the paging message and reduce the power consumption of the terminal device.
