Description

[0001] This application is a divisional application. The application number of the original application is 202010791001.8, and the original application date is August 7, 2020. The entire contents of the original application are incorporated into this application by reference. Technical Field

[0002] The embodiments of the present application relate to the field of communication technology, and in particular, to a paging method and device. Background Art

[0003] When the terminal is in idle or inactive state, it will periodically receive paging initiated by the network side. For example, the terminal calculates a paging frame and the paging occasion in the PF, and monitors the downlink control information (DCI) used to schedule the paging message in the PO. If the DCI is detected and the detected DCI schedules the physical downlink shared channel (PDSCH) carrying the paging message, the PDSCH carrying the paging message is received at the position indicated by the DCI, and the terminal determines whether it has been paged according to the paging message carried by the PDSCH.

[0004] Among them, before the terminal monitors DCI in PO, the terminal needs to receive one or more synchronization signal blocks (SSB) sent by the network side, and use SSB for time / frequency synchronization, automatic gain control (AGC) adjustment, etc., in order to correctly receive DCI, that is, the terminal needs to consume energy to receive one or more SSBs before monitoring DCI. After receiving SSB to PO, or between two SSBs, although the terminal does not need to receive signals, it needs to maintain a working state in order to prepare for communication, which consumes a certain amount of energy.

[0005] In the research stage of terminal energy saving, how to reduce the energy consumption of the terminal during the paging process is a problem that needs to be solved urgently. Summary of the invention

[0006] The embodiments of the present application provide a paging method and device to solve the problem of high energy consumption of a terminal when paging a terminal.

[0007] In order to achieve the above objectives, the embodiments of the present application adopt the following technical solutions:

[0008] In a first aspect, the present application provides a paging method, the method comprising: before the paging opportunity of the terminal, the terminal receives a first paging indication including a first field sent by a network device, the first field being used to indicate whether to send a paging within R paging opportunities including the paging opportunity of the terminal, and the terminal determines whether to monitor the DCI used to schedule the paging message at the paging opportunity of the terminal based on the first paging opportunity.

[0009] Based on the method described in the first aspect, a paging indication can be set in advance before the paging opportunity, and the paging indication can be used to indicate in advance to the terminal whether there is paging during the paging opportunity, so that when there is no paging during the paging opportunity, the terminal is triggered to stop working in advance and enter a sleep state, thereby reducing the energy consumption of the terminal. At the same time, the method described in the first aspect can also use one paging indication to indicate multiple paging opportunities to achieve the purpose of indicating whether there is paging in multiple paging opportunities at one time, thereby saving signaling overhead.

[0010] In one possible design, the first field includes R indication information, and the i-th indication information among the R indication information indicates whether to send a paging in the i-th paging opportunity among the R paging opportunities, and i is an integer greater than or equal to 1 and less than or equal to R. Based on this possible design, indication information corresponding to the paging opportunity one by one can be designed in the paging indication, so that the terminal can distinguish the indication information corresponding to its own paging opportunity from multiple indication information, thereby simplifying the system design.

[0011] In a possible design, the terminal determines whether to monitor downlink control information DCI on the terminal's paging opportunity according to the first paging opportunity, including: the terminal determines the indication information corresponding to the terminal's paging opportunity according to the time domain position of the terminal's paging opportunity in R paging opportunities, and determines whether to monitor DCI on the terminal's paging opportunity according to the indication information corresponding to the terminal's paging opportunity. Based on this possible design, the terminal can find the indication information corresponding to its own paging opportunity based on the time domain positions of multiple paging opportunities corresponding to the paging indication, and determine whether to continue monitoring DCI according to the paging indication corresponding to its own paging opportunity, thereby improving the accuracy of the terminal's pre-acquisition of whether there is a paging message in its own paging opportunity, and at the same time, simplifying the system design.

[0012] In a possible design, the terminal receives a first paging indication sent by a network device before the terminal's paging opportunity, including: the terminal determines K paging indications corresponding to the terminal's paging opportunity according to the time domain position of the terminal's paging opportunity, where K is an integer greater than or equal to 1, the terminal receives K paging indications before the paging opportunity, and determines the first paging indication from the K paging indications. Based on this possible design, a paging opportunity can be set to correspond to multiple paging indications. By designing multiple paging indications, it is maximized to ensure that the terminal can receive the paging indication of its own paging opportunity, so as to know in advance whether there is paging in the paging opportunity, thereby saving energy consumption.

[0013] In one possible design, K is configured to the terminal by the network device, that is, the network device uniformly manages the number of paging indications corresponding to the paging occasions, so that the configuration of each terminal is unified, which is easy to manage and improves the configuration flexibility of the network device.

[0014] In one possible design, the terminal receives a first paging indication sent by a network device before the terminal's paging opportunity, including: the terminal receives a first paging indication sent by a network device within a monitoring time interval, and a monitoring time interval is designed to receive the paging indication, thereby simplifying the system design.

[0015] In one possible design, the terminal receives monitoring time window configuration information sent by the network device for determining the monitoring time interval, and determines the monitoring time interval based on the monitoring time window configuration information. That is, the monitoring time interval is configured by the network device, so that the configuration of each terminal is unified, management is facilitated, and the configuration flexibility of the network device is improved.

[0016] In one possible design, the R paging occasions are the R paging occasions closest to the first paging indication after the first paging indication. This can make the time domain position of the paging indication and the paging occasion close, shorten the time interval between the paging occasion and the paging indication, and avoid the problem of excessive energy consumption caused by the terminal monitoring the DCI on the paging occasion for a long time after receiving the paging indication when there is paging in the paging indication paging occasion.

[0017] In one possible design, R is configured to the terminal by the network device, that is, the value of R is configured by the network device, so that the configuration of each terminal is unified, management is convenient, and the configuration flexibility of the network device is improved.

[0018] In a possible design, the first field includes indication information corresponding to each of the R paging occasions, and the indication information corresponding to each of the R paging occasions includes M bits, and the M bits are used to indicate whether there is paging in the paging occasion corresponding to the indication information, and M is an integer greater than or equal to 1. Based on this possible design, the indication information indicating the paging occasion may include multiple bits, that is, the paging occasions are grouped to reduce the false alarm probability of the terminal and increase the probability of the terminal being successfully paged.

[0019] In one possible design, M is configured to the terminal by the network device; or, M satisfies the formula: A is the length of a paging indication, and B is the length of the field indicating valid information in the paging indication except the first field. Based on this possible design, the number of bits of blank padding in the paging indication can be made as small as possible, the number of bits of valid information can be made as large as possible, and the number M of further grouping of paging occasions can be made as large as possible, thereby reducing the probability of false alarm of paging of the terminal and increasing the probability of successful paging of the terminal.

[0020] In one possible design, the first field includes indication information corresponding to each of the R paging occasions; The indication information corresponding to each paging occasion includes: bits; the indication information corresponding to each paging opportunity in the remaining paging opportunities of R paging opportunities includes bits; A is the length of the paging indication, and B is the length of the field indicating valid information in the paging indication except the first field. Based on this possible design, the existence of padding bits can be completely avoided, the number of bits of valid information can be maximized as much as possible, the number M of further grouping of paging occasions can be as large as possible, the probability of false alarm of paging of the terminal is reduced, and the probability of successful paging of the terminal is increased.

[0021] In a possible design, the paging indication further includes one or more of the following fields: a second field, a third field, and a fourth field; the second field is used to indicate whether the paging indication includes an SM; the third field is used to indicate an SM; the fourth field is used to indicate the availability of an auxiliary reference signal, where the auxiliary reference signal is an auxiliary reference signal configured by a network device, or an auxiliary reference signal associated with R paging occasions. Based on this possible design, some fields for indicating useful information can be set in advance in the paging indication so that the terminal can be informed of the useful information in advance, thereby avoiding the energy consumption caused by the terminal having to obtain the useful information from the DCI or other information after pre-synchronization.

[0022] In a possible design, the second field is information common to R paging occasions. Based on this possible design, the second field can be set to information common to multiple paging occasions to reduce overhead.

[0023] In one possible design, the SM indicates one or more of the following information: system message change indication information, earthquake and tsunami warning information, commercial mobile alarm information, and indication information for stopping monitoring paging messages. Based on this, as much useful information as possible can be carried in the SM to improve the scope of use of the information indicated by the SM.

[0024] In one possible design, the length of the third field is configured by the network device. Based on this possible design, the length of the third field can be configured by the network device, thereby improving the configuration flexibility and control rights of the network device.

[0025] In a possible design, the third field is information common to R paging occasions. Based on this possible design, the third field can be set to information common to multiple paging occasions to reduce overhead.

[0026] In a possible design, the fourth field is used to indicate the availability of the auxiliary reference signal, including: the length of the fourth field is equal to the number of auxiliary reference signals or auxiliary reference signal groups configured by the network device, wherein the auxiliary reference signal group includes one or more auxiliary reference signals; or, the length of the fourth field is equal to the number of auxiliary reference signals or auxiliary reference signal groups associated with R paging occasions, or, the fourth field includes R subfields, the R subfields correspond to the R paging occasions, and one subfield is used to indicate the availability of the auxiliary reference signal associated with the paging occasion corresponding to the subfield. Based on this possible design, the availability of the auxiliary reference signal or the auxiliary reference signal group can be indicated by the fourth field, and the indication method is flexible and diverse, and has a wide applicability.

[0027] In one possible design, the first paging indication also includes a fifth field; the fifth field is used to indicate the number of paging occasions indicated by the first field; or, the fifth field is used to indicate the length of the first field, so that it is convenient to more flexibly adjust the number of paging indications indicated by the first field or the length of the first field.

[0028] In one possible design, the first field in different paging indications has the same indication content for the same paging occasion, so as to avoid the possibility that the indication information corresponding to the paging occasion received by the terminal may be inconsistent, resulting in the terminal being unable to achieve the purpose of energy saving through the paging indication.

[0029] In one possible design, the first paging indication and the synchronization signal block SSB closest to the first paging indication are in a QCL relationship; or, the first paging indication and the SSB associated with the first paging indication are in a QCL relationship, so that the terminal receives the paging indication according to the receiving beam of the SSB, thereby improving the accuracy of the terminal receiving the paging indication.

[0056] Before introducing the embodiments of the present application, some terms involved in the embodiments of the present application (such as paging, PO and DCI, etc.) are explained. It should be noted that the following explanations are intended to make the embodiments of the present application easier to understand and should not be regarded as limiting the scope of protection required by the embodiments of the present application.

[0057] Paging: It is a process in which a network-side device periodically sends a paging message to a terminal in an idle state or an inactive state, in order to wake up the terminal in an idle state or an inactive state and return it to a connected state. A paging process may include: on the network side, a network-side device (such as an access network device) calculates the paging occasion (PO) corresponding to the terminal, and sends a physical downlink control channel (PDCCH) carrying DCI to the terminal on the terminal's PO. The DCI may be used to indicate whether the DCI schedules a PDSCH carrying a paging message. If the DCI indicates that a PDSCH carrying a paging message is scheduled, the network-side device sends the PDSCH carrying the paging message at the resource location indicated by the DCI. On the terminal side, the terminal calculates its corresponding PO, and uses its own paging-radio network temporary identity (P-RNTI) to monitor DCI within the calculated PO. If DCI is detected and the DCI indicates that a PDSCH carrying a paging message is scheduled, the terminal receives the PDSCH carrying the paging message at the resource location indicated by the DCI, and determines whether it has been paged based on the paging message carried by the PDSCH. For example, the paging message may carry the identification information of the paged terminal (such as the terminal's user equipment identifier (UE_ID)). If the paging message received by the terminal carries its own identification information, it determines that it has been paged, otherwise, it determines that it has not been paged. If the terminal is paged, the terminal initiates a random access process and switches to the connected state.

[0058] PO: It is the time domain position / time interval of the DCI of the PDSCH carrying the paging message that the terminal monitors and schedules. When determining the position of the PO, you must first confirm the position of a paging frame (PF), and then determine the final position of the PO based on the relative position of the PO in the PF. A PF can be associated with one or more POs. The POs in a PF are arranged continuously starting from the starting position of the PF. For example, the starting position of the first PO in the PF is the same as the starting position of the PF, and then the starting position of the second PO overlaps with the ending position of the first PO, and so on. Multiple POs are set. The length of a PO can be several time slots. Specifically, the system frame number (SFN) of the PF can be calculated using the following formula (1) based on the user equipment identifier (UE_ID) of the terminal, and the sequence number i_s of the PO that the terminal needs to monitor can be calculated using the following formula (2):

[0059] (SFN + PF_offset)mod T=(T div N)*(UE_ID mod N) Formula (1)

[0060] i_s = floor (UE_ID / N) mod Ns formula (2)

[0061] Among them, PF_offset in the above formula is an offset value used to determine PF. PF_offset can be pre-defined by the protocol or determined by the access network device and configured to the terminal. T is the discontinuous reception (DRX) cycle, N is the number of PFs in the DRX cycle T, and Ns is the number of POs in a PF. "mod" represents the remainder obtained by dividing the two numbers before and after mod. Floor() is rounded down. "*" is multiplication calculation. "div" is division calculation. (SFN+PF_offset)mod T=(T div N)*(UE_ID mod N) means that all terminals are divided into N groups according to UE_ID. The value of UE_ID mod N can determine which group the terminal is in and which PF it corresponds to. For example, taking N=4 as an example, if UE_ID is a string of binary numbers, the value of the last two bits of UE_ID determines which PF the terminal is in. floor(UE_ID / N)mod Ns is equivalent to further dividing the terminal's PF into Ns groups. According to the value of floor(UE_ID / N)mod Ns, the terminal's specific group, that is, PO, can be determined. Among them, the value of UE_ID is the terminal's 5G-S temporary mobile subscriber identity (5G S-temporary mobile subscriber identity, 5G-S-TMSI) mod 1024.

[0062] In general, there are N*Ns POs in a DRX cycle, and the terminals are divided into N*Ns groups according to UE_ID, with each group corresponding to one PO. Figure 1a This is a schematic diagram of N=4, Ns=5, as shown in Figure 1a As shown, there are four PFs and one PF has five POs. The terminal can calculate which PO of which PF it monitors DCI on according to the above formula (1) and formula (2).

[0063] Furthermore, in order to match the beam-based transmission in the NR system design, the PO can also be divided into multiple monitoring occasions (MO), and different MOs are associated with different SSBs, that is, associated with different beam directions. The number of MOs contained in a PO is determined by the number of SSBs actually sent in an SSB cycle, and the number of SSBs actually sent in an SSB cycle is configured by the network device through system messages.

[0064] It should be noted that, in the present application, the DRX cycle T, the number of PFs N in the DRX cycle, and the number of POs Ns in a PF can be dynamically set as needed or pre-specified by the protocol and are not limited.

[0065] DCI: can be used to indicate whether to send a paging message and to schedule the PDSCH that carries the paging message. In this application, DCI can also be named paging DCI or scheduling information or other names, etc., without limitation. DCI can include multiple fields. The position of each field in the DCI, the number of bits occupied by each field, and the meaning indicated by the value of each field can be pre-defined by the protocol or determined according to the network device configuration. The fields included in DCI are introduced below:

[0066] (1) Short message indicator (SMI) field.

[0067] The SMI field occupies 2 bits, the first bit is used to indicate whether the current DCI carries short messages (SM), and the second bit is used to indicate whether the current DCI schedules a PDSCH carrying a paging message.

[0068] (2) Short messages (SMI) field.

[0069] The SMI field occupies 8 bits, the first bit indicates the system information change (SI change), the second bit indicates the earthquake and tsunami warning system (ETWS) and / or the commercial mobile alert system (CMAS), the third bit indicates whether to stop reading paging messages in the unlicensed spectrum (NR unlicensed, NRU), and the remaining last 5 bits are reserved. The reserved bits can be used to indicate other information, such as information that can be used to indicate subsequent expansion with the development of communication technology.

[0070] It should be noted that if the first bit in the SMI field indicates that the current DCI carries an SM, the SMI field corresponds to 8 bits, of which the first three bits are respectively filled with SI change information, ETWS information, and indication information for indicating whether to stop reading paging messages in the NRU. If the first bit in the SIM field indicates that the current DCI does not carry an SM, the 8 bits corresponding to the SM field are meaningless bits and do not indicate anything.

[0071] (3) Frequency domain resource assignment (FDRA) field.

[0072] The FDRA field can be used to indicate the frequency domain resources used for PDSCH transmission, including which physical resource blocks (PRBs) are used for data transmission. The number of bits occupied by the FDRA field is determined according to the bandwidth size of the control resource set (CORESET) 0.

[0073] (4) Time domain resource assignment (TDRA) field.

[0074] The TDRA field occupies 4 bits and can be used to indicate the time domain resources used for PDSCH transmission, including the time slot used for data transmission and the symbols used in the time slot.

[0075] (5) Virtual resource block (VRB) to physical resource block (PRB) mapping field.

[0076] The VRB-to-PRB mapping field occupies 1 bit. The VRB-to-PRB mapping field can be used to indicate the mapping method used when mapping VRB to PRB, which can be interleaved mapping or non-interleaved mapping.

[0077] (6) Modulation and coding scheme (MCS) field.

[0078] The MCS field may occupy 5 bits, and the MCS field may be used to specify the modulation and coding scheme used when transmitting the PDSCH.

[0079] (7) Transport block scaling (TB scaling) field.

[0080] The TB scaling field may occupy 2 bits and is used to indicate whether the size of the transport block (TB) carried in the PDSCH carrying the paging message is scaled and what the scaling ratio is.

[0081] (8) Reserved fields.

[0082] The reserved field can occupy 6 bits.

[0083] In the case that there are N PFs in a DRX cycle and a PF is divided into Ns POs, there are only N*Ns groups of POs in a DRX cycle. In this way, multiple terminals will monitor the DCI in the same PO in a DRX cycle. When multiple terminals monitor the DCI in the same PO, when a terminal receives DCI in its corresponding PO, it only knows that a terminal in the current PO has been paged, but does not know whether it is itself that has been paged. Only after receiving the DCI, it further receives the PDSCH carrying the paging message according to the instruction of the DCI, and checks the paging message carried by the PDSCH to see whether the paged terminals include itself. If it does, it is paged, and if not, it is not paged. However, the probability of a terminal being paged is relatively small, but because there are a large number of terminals monitoring the DCI in the same PO, the probability of the network side device sending paging DCI is high, and the terminal is also more likely to be in a false alarm state of paging. The false alarm state of paging means that the terminal has received the paging DCI and the PDSCH carrying the paging message, but has not been paged.

[0084] Among them, in order for the terminal to correctly receive DCI and the PDSCH carrying paging messages scheduled by DCI, and determine whether it is in a "false alarm of paging" or being paged according to the received DCI and PDSCH, the following process needs to be performed: the access network device periodically sends one or more synchronization signals and physical broadcast channel (physicalbroadcast channel, PBCH) blocks (synchronization signal and PBCH block, SSB) to the terminal before the PO of the terminal. After the terminal calculates its own PO, before monitoring DCI within the PO, the terminal will select one or more SSBs that are closer to the PO from the SSBs before the PO, receive the SSB at the resource position of the selected SSB, and perform time / frequency synchronization, automatic gain control (automatic gain control, AGC) adjustment and other steps with the access network device based on the received SSB.

[0085] In this application, the steps of using SSB for time / frequency synchronization and AGC adjustment by the terminal can be collectively referred to as pre-synchronization. In addition, although the access network device will send multiple SSBs in one SSB cycle, each SSB in one SSB cycle usually corresponds to a different beam transmission direction. For the same terminal, the SSB used for pre-synchronization should correspond to the same beam transmission direction. Therefore, one or more SSBs used by the terminal for pre-synchronization are usually located in different SSB cycles.

[0086] It should be noted that, in the present application, the period of sending SSB, the time interval between adjacent SSBs, and the resource location of SSB can be pre-specified by the protocol or configured to the terminal by the network side device through a system message. The SSB before PO may refer to an SSB whose time domain position is before PO and whose time domain position does not overlap with the time domain position of PO. The SSB before the PO of the terminal are all SSBs that can be used / capable of being used for terminal pre-synchronization. These SSBs can be called available SSBs, which are uniformly described here and will not be repeated below.

[0087] For example, Figure 1b As shown in the figure, it is a schematic diagram of the relationship between a PO and an SSB. Before the time domain position of the PO, there are two SSBs. These two SSBs can be called available SSBs. The terminal can select to receive the SSB closest to the PO from these two SSBs for pre-synchronization, or it can select to receive these two SSBs for pre-synchronization. Figure 1b In this case, the two SSBs can be located in different SSB periods.

[0088] For example, Figure 1c As shown in FIG. 1 , it is a schematic diagram of the time domain position relationship between multiple POs and SSBs. Figure 1c As shown, there are SSB1 to SSB5 before PO5, SSB1 to SSB4 before PO4, SSB1 to SSB3 before PO3, SSB1 to SSB3 before PO2, and SSB1 to SSB2 before PO1. If the terminal's PO is Figure 1c If the terminal's PO is PO5, the terminal can choose to receive one, two, three or four SSBs closest to PO5 from SSB1 to SSB5 before PO5 for pre-synchronization, or it can choose to receive these five SSBs for pre-synchronization. Figure 1c If PO4 is selected, the terminal can choose to receive one, two or three SSBs closest to PO4 among SSB1 to SSB4 for pre-synchronization, or can choose to receive these four SSBs for pre-synchronization. Figure 1cThe upper and lower relationship between SSB and PO is mainly to prevent the two from overlapping and making it difficult to distinguish the time domain position relationship. It does not represent the specific frequency domain position relationship between PO and SSB, that is, Figure 1c It mainly represents the position of the two in the time domain. Figure 1c In the example, SSB1 to SSB5 can be located in different SSB periods.

[0089] Specifically, the terminal can determine which SSB among the available SSBs to start receiving the SSB sent by the access network device, i.e., determine which available SSBs can be used for pre-synchronization, based on the channel quality between itself and the access network device (such as reference signal receiving power (RSRP) or reference signal received quality (RSRQ) or signal to interference plus noise ratio (SINR), etc.) and / or its own hardware processing conditions. Taking the example of the terminal determining which SSBs are used for pre-synchronization based on the channel quality between itself and the access network device, the closer the terminal is to the access network device, the higher the SINR, the better the terminal coverage, the stronger the SSB signal, and the fewer the number of SSBs used by the terminal for pre-synchronization. When the terminal is far away from the access network device, the SINR is lower, the worse the terminal coverage, the weaker the SSB signal, and the more SSBs are used by the terminal for pre-synchronization.

[0090] For example, Figure 1d As shown, the PO of UE1 and UE2 is PO1, and the two SSBs in front of PO1 can be used as available SSBs for pre-synchronization. Specifically, if the coverage of UE1 is poor, SSB1 and SSB2 are used for pre-synchronization. If the coverage of UE2 is good, UE2 can use one SSB (such as SSB2 closest to PO1) for pre-synchronization.

[0091] The terminal needs to consume energy to receive SSB. During the time from receiving SSB to PO, or, when receiving multiple SSBs, during the time between two adjacent SSBs, although the terminal does not need to receive signals, in order to prepare for "communication (such as preparing to monitor the DCI on PO or accurately receiving the next SSB)", the terminal needs to keep working at all times, and being in the working state causes the terminal to consume a certain amount of energy.

[0092] For example, Figure 1dFor example, UE1 receives SSB1. After receiving SSB1, UE1 continues to work and receives SSB2. It performs pre-synchronization based on SSB1 and SSB2. After the pre-synchronization is successful, UE1 continues to work and monitors DCI on PO1 of UE1. That is, UE1 needs to keep working from the time it starts receiving SSB1 to the time it monitors DCI on PO1, consuming its own energy. Similarly, UE2 also needs to start working and prepare to receive SSB2. After receiving SSB2, it performs pre-synchronization based on SSB2. After the pre-synchronization is successful, it continues to work and monitors DCI on PO1 of UE2. UE2 needs to keep working from the time it starts receiving SSB2 to the time it monitors DCI on PO1, consuming its own energy.

[0093] As can be seen from the above, in the process of receiving paging messages, a large part of the energy consumption of the terminal is in the process of receiving SSB for pre-synchronization, especially in the period of "not receiving signals but still maintaining working state", which will also consume a certain amount of energy. In addition, since multiple terminals need to monitor the DCI in the same PO in a DRX cycle, each terminal must perform pre-synchronization, receive DCI and PDSCH in order to determine whether it has been paged, that is, the above-mentioned additional energy consumption is inevitable.

[0094] However, most terminals have high requirements for energy saving. If the terminal consumes too much energy, it will affect the terminal's performance and reduce the user experience. In view of this, the embodiment of the present application proposes the following solution: before the PO (such as when the terminal is pre-synchronized), the terminal is informed whether to send a paging in the PO, so that the terminal can know whether it can be paged earlier, and stop working as soon as possible if it is not paged, and do not keep working all the time, so as to avoid unnecessary energy consumption. For example, Figure 1e As shown, if UE1 learns that it has not been paged near SSB1, UE1 will not keep working later. If UE2 learns that it has not been paged near SSB2, UE2 will not keep working anymore. Figure 1d , the energy consumption of UE11 and UE12 will be significantly reduced.

[0095] In the present application, the information indicating whether to send a paging in a PO may be named a paging indication. It should be noted that the present application does not limit the naming of the paging indication, and the paging indication may also be named a wake-up signal (WUS) or an early paging indication (early paging indication or early transmitted paging indication) or a pre-paging indication (pre-paging indication) or other names, etc., without limitation.

[0096] However, if the location of the paging indication corresponding to the PO is not designed properly, some terminals may still need to consume a large amount of energy. Figure 1f As shown in the figure, UE1 is a UE with poor coverage, and UE2 is a UE with good coverage. The paging indication can be sent near SSB1 or near SSB2. If the paging indication is only sent near SSB1, the power consumption of UE1 and UE2 when the paging indication indicates whether there is paging in PO1 is as follows: Figure 1f Similarly, the paging indication is only sent near SSB2, and the power consumption of UE1 and UE2 when the paging indication indicates whether there is paging in PO1 is as follows: Figure 1f As shown. It can be seen that UE2 does not need to use SSB1 for pre-synchronization, but when the paging indication is only sent near SSB1, UE2 needs to receive SSB1 in order to receive the paging indication, and after being indicated that there is a paging, it still needs to maintain a certain working state until PO1. This can be compared Figure 1f The circled part in line 3 and Figure 1f In addition, if the paging indication is only sent near SSB2, UE1 cannot know in advance whether there is paging. In order to ensure that it can correctly receive paging when there is paging, it needs to receive SSB1 and maintain the working state until it receives the paging indication after SSB2. If it is indicated that there is no paging, then Figure 1f The circled part in line 6 and Figure 1f From the comparison of the second row in the figure, it can be seen that some energy is wasted.

[0097] from Figure 1f It can be seen that even if a paging indication is designed to indicate whether there is paging in the PO, for some terminals, some energy may be wasted in the process of receiving paging messages. For the terminal, the best solution is to "receive the paging indication near the first SSB that it needs to receive." However, multiple terminals need to monitor the DCI in the same PO within a DRX cycle, and the coverage and / or hardware processing conditions of each terminal may be different. The number of SSBs received by each terminal may be different, and the starting point for pre-synchronization of different terminals is different, that is, the first SSB corresponding to different terminals may be different. The access network equipment cannot know which SSB is the first SSB received by most terminals, and thus cannot send the paging indication at the first SSB used by most terminals, thereby reducing the energy consumption of most terminals.

[0098] In order to maximize the guarantee that each terminal can receive the paging indication near its corresponding first SSB, the best solution is to send the paging indication corresponding to the same PO near multiple SSBs before the PO, that is, the paging indication corresponding to a PO will be sent near multiple SSBs. This has the following two advantages: on the one hand, it can ensure that the terminal corresponding to the PO has a greater probability of receiving the paging indication near its first SSB, and stop working as soon as possible according to the instructions of the paging indication, and enter a dormant state, thereby reducing energy consumption. On the other hand, when PO is divided into multiple MOs, and different MOs correspond to different SSBs in an SSB cycle, if one PO corresponds to paging indications near multiple SSBs, and these multiple SSBs preferably correspond one-to-one with the multiple MOs obtained by dividing a PO, then the terminal corresponding to each MO can receive the paging indication near the SSB, and the purpose of reducing energy consumption can be achieved according to the instructions of the paging indication. For example, Figure 1f As shown, paging indications are sent near SSB1 and SSB2, that is, there can be multiple paging indications for the same PO to indicate whether there is paging in the PO, so as to ensure that most terminals monitoring the DCI on the PO can receive the paging indication near the first SSB they need to receive.

[0099] It should be noted that when a PO corresponds to paging indications near multiple SSBs, these multiple SSBs may be located in the same or different SSB cycles. For example, when multiple SSBs correspond to multiple MOs, the multiple SSBs are located in the same SSB cycle. When multiple SSBs correspond to the same MO, the multiple SSBs are located in different SSB cycles. Figure 1g As shown in the figure, there are 5 SSB cycles, and 4 SSBs are sent in each SSB cycle. The indexes of each SSB are SSB0 to SSB3. At this time, there will be 4 MOs in a PO, with indexes 0 to 3. Each SSB will correspond to each MO in the PO, that is, SSB0 corresponds to MO0, SSB1 corresponds to MO1, SSB2 corresponds to MO2, and SSB3 corresponds to MO3. The relationship is as follows: Figure 1g As shown, the parts with the same fill pattern represent the corresponding SSB and MO.

[0100] In addition, since the SSBs before different POs may overlap, different POs may be associated with the same SSB. Therefore, for the paging indication near the same SSB, it may be associated with multiple POs, and it is necessary to indicate whether there is paging in multiple POs. Figure 1cAs shown, the SSBs before PO2 are SSB1 to SSB3, and the SSBs before PO1 are SSB1 to SSB2. There are two overlapping SSBs before two different POs: SSB1 and SSB2. At this time, SSB1 and / or SSB2 can be associated with PO1 and PO2, and used as pre-synchronization for the terminals corresponding to PO1 and PO2. Taking the association of SSB2 with PO1 and PO2 as an example, the paging indication near SSB2 can be associated with PO1 and PO2 to indicate whether there is paging in PO1 and PO2.

[0101] It should be noted that the SSB described in the present application may refer to one or more SSBs that are closest to the PO before the paging opportunity, and the paging indication near the SSB may refer to a paging indication starting from the end time of the SSB, or a paging indication after the end time of the SSB and whose time difference from the end time of the SSB is less than a preset time threshold, or a paging indication after the end time of the SSB and closer to the SSB. Among them, the preset time threshold can be set as needed and is not restricted. In addition, the present application does not limit the SSB to the SSB that is closest to the PO before the paging opportunity. Alternatively, the corresponding SSB can be pre-configured for the paging opportunity, that is, the paging opportunity is associated with the SSB. At this time, the paging indication corresponding to the paging opportunity can be located near the SSB.

[0102] The following describes the design method of the paging indication by taking the paging indication being associated with R paging occasions and used to indicate whether there is paging within the R paging occasions, where R is an integer greater than or equal to 1 as an example.

[0103] First, in order to enable the paging indication to have the function of indicating whether there is paging in multiple POs, the paging indication may at least include a first field, and the first field may be used to indicate whether there is paging in R POs.

[0104] It should be noted that, in the present application, the R POs indicated by the first field may be different POs in the same DRX cycle or POs in different DRX cycles or POs appearing in different DRX cycles, without limitation. Specifically, the R POs may be POs appearing in the same DRX cycle. In this case, the R POs are different POs. For example, assuming that the first field indicates whether there is paging in PO1, PO2, and PO3, PO1, PO2, and PO3 may be different POs appearing in the same DRX cycle 1. Alternatively, the R POs may be POs appearing in different DRX cycles. For example, assuming that the first field indicates whether there is paging in PO1, PO2, and PO3, PO1 may be a PO in DRX cycle 1, PO2 and PO3 may be POs in DRX cycle 2, and the three are different POs. Alternatively, the R POs may be multiple periodic occurrences of the R POs in multiple DRX cycles, that is, the first field is used to indicate whether one or several POs have paging in consecutive R DRX cycles, so that when the PO has no paging in consecutive DRX cycles, it indicates in advance that the terminal has been in a dormant state in these DRX cycles, thereby achieving the purpose of long-term energy saving. For example, the first field can be used to indicate whether there is paging in PO1 in DRX cycle 1, PO in DRX cycle 2, and PO3 in DRX cycle 3, that is, the first field is used to indicate whether there is paging in the same PO sent periodically, or the first field can indicate whether there is paging in PO1 in DRX cycle 1, PO in DRX cycle 2, and PO1 in DRX cycle 1 and PO2 in DRX cycle 2.

[0105] Exemplarily, the first field may include R indication information, the R indication information corresponds one-to-one to the R paging occasions, the i-th indication information among the R indication information indicates whether paging is sent in the i-th paging occasion among the R paging occasions, and i is an integer greater than or equal to 1 and less than or equal to R.

[0106] Among them, the present application does not limit the order of the R indication information in the first field. The R indication information can be arranged in the first field according to the time domain positions of the R paging occasions, such as according to the order of the time domain positions, the indication information corresponding to the paging occasions with earlier time domain positions are arranged in front, and the indication information corresponding to the paging occasions with later time domain positions are arranged in the back; or, the indication information corresponding to the paging occasions with earlier time domain positions are arranged in the back, and the indication information corresponding to the paging occasions with later time domain positions are arranged in the front, or they can be arranged in the first field according to the preset order without limitation. For example, the paging indication near SSB2 needs to indicate the information of PO1, PO2 and PO3. Since the order of the three POs is PO1 to PO3, the order of these three indication information in the DCI is the indication information of PO1, the indication information of PO2, and the indication information of PO3.

[0107] In one example, if the terminals in the same paging occasion are not grouped, each indication information may include a bit, which is used to indicate whether there is paging in a paging occasion, such as a binary bit "1" indicates that there is paging in the paging occasion, and a binary bit "0" indicates that there is no paging in the paging occasion.

[0108] In another example, if the terminals in the same paging opportunity are divided into multiple groups, such as M groups, the indication information corresponding to the paging opportunity may include M bits, one bit is used to indicate whether there is paging in a group, wherein the M bits in the indication information may be arranged in the indication information in order according to the group numbers of the M groups. Specifically, which group a terminal belongs to can be calculated based on UE_ID, such as floor(floor(UE_ID / N) / Ns)mod M, or floor(UE_ID / N / Ns)mod M. In this way, the number of terminals in a group can be further reduced, such as from N*Ns group to N*Ns*M group, the false alarm probability of the terminals in each group of N*Ns*M group can be reduced, thereby increasing the probability of the terminal being successfully paged.

[0109] In another example, if the R POs indicated by the first field are POs located in several consecutive DRX cycles, that is, the first field is used to indicate whether one or several POs have been paged in Q consecutive DRX cycles, then the specific indication method of the first field may include the following situations: Case 1. If the terminals within the paging opportunity are not grouped, and the first field is used to indicate whether the same PO has been paged in R consecutive DRX cycles, that is, Q=R at this time, then the first field includes an indication information, and the indication information may include a bit number, and the bit number is used to indicate whether the PO has been paged in R consecutive DRX cycles, or, the indication information may include R bits, and the jth bit number is used to indicate whether the PO has been paged in the jth DRX cycle; or, the first field includes R indication information, and one indication information may include a bit number, and the i-th indication information is used to indicate whether the PO has been paged in the j-th DRX cycle, where j is an integer greater than or equal to 1 and less than or equal to R.

[0110] Case 2: If the terminals within the paging occasion are not grouped, and the first field is used to indicate whether multiple different POs (such as P POs) have been paged within Q consecutive DRX cycles, P and Q are positive integers, P*Q=R, then the first field includes P indication information, one indication information may include a bit number, the i-th indication information is used to indicate whether the i-th PO has been paged within Q consecutive DRX cycles, or, the first field includes P indication information, one indication information may include Q bits, the j-th bit number in the i-th indication information is used to indicate whether the i-th PO has been paged within the j-th DRX cycle; or, the first field includes R indication information, one indication information may include a bit number, the i-th indication information is used to indicate whether the i-th PO has been paged within the j-th DRX cycle, and j is an integer greater than or equal to 1 and less than or equal to R.

[0111] Case 3: If the terminals within the paging occasion are divided into M groups, and the first field is used to indicate whether multiple different POs (such as P POs) have been paged within Q consecutive DRX cycles, P and Q are positive integers, P*Q=R, then the first field includes P indication information, one indication information may include M bits, and the sth bit in the ith indication information may be used to indicate whether the sth group in the ith PO has been paged within Q consecutive DRX cycles, and s is an integer greater than or equal to 1 and less than M. Alternatively, the first field includes P indication information, one indication information may include Q*M bits, and the sth bit in the ith indication information is used to indicate whether the sth group in the ith PO has been paged within the jth DRX cycle.

[0112] In the present application, the number of paging occasions corresponding to different paging indications may be the same or different, that is, the number of paging occasions corresponding to the paging indications may be fixed or dynamically adjusted. The number of indication information included in the first field of different paging indications may be the same or different, that is, the number of indication information included in the first field changes with the change of the paging occasion corresponding to the paging indication, and may be a fixed number or a dynamically adjusted number. The number of bits included in different indication information may be the same or different, and may be a fixed number or a dynamically adjusted number.

[0113] Furthermore, the information included in the SM is also very important for the terminal. If the SMI and SM in the DCI are not included in the paging indication, in order to confirm whether there is an SM and further confirm whether there is one or more of the following information in the SM: system message change indication information, earthquake and tsunami warning and commercial mobile alert information, and indication information for stopping monitoring paging messages, the terminal still needs to receive DCI on the PO and obtain the SM from the DCI even if it knows that no paging message is sent. In this way, the terminal needs to maintain the working state to the PO anyway, which consumes a lot of energy.

[0114] In order to avoid the energy consumption caused by the terminal monitoring the SMI carried by the DCI and obtaining the SM, the paging indication may further carry a second field and a third field, and the second field and the third field can be used by the terminal to obtain some information included in the SM before the terminal's PO. Since the information included in the SM, such as SI change information, ETWS information, etc., does not change very frequently, the SM sent in multiple adjacent POs should usually be the same. Therefore, when a paging indication is used to indicate whether there is paging in R adjacent POs, if the paging indication contains the second field and the third field, the information contained in the second field and the third field can be information common to the R POs, called PO common information, and the second field and the third field can be directed to all terminals corresponding to the R POs. For all terminals corresponding to the R POs, the contents indicated by the second field and the third field are the same.

[0115] The second field may be used to indicate whether the paging indication includes SM, and the second field may occupy 1 bit, which may be used to indicate whether the paging indication includes SM. The second field may be named SMI, except that the number of bits occupied by the SMI in the paging indication and the SMI in the DCI are different (or called length), and the content indicated is different.

[0116] The third field may be used to indicate SM, and SM may include one or more of system message change indication information, earthquake tsunami warning and commercial mobile alarm information, and indication information for stopping monitoring paging messages. The length of the third field (or the number of bits occupied) may be specified in the protocol or configured by a network device (such as an access network device), such as the access network device may configure the length of the third field according to the information indicated to the terminal as needed.

[0117] Exemplarily, the third field may be specified or configured to occupy 2 bits, 3 bits, or 8 bits, etc., without limitation. If the third field occupies 2 bits, then when the second field indicates the presence of SM, the third field may carry SIchange information and ETWS information. If the third field occupies 3 bits, then when the second field indicates the presence of SM, the third field may carry SI change information, ETWS information, and information on whether to stop paging (stop-paging) within the NRU. If the third field occupies 8 bits, then when the second field indicates the presence of SM, the third field may carry SIchange information, ETWS information, and information on whether to stop paging (stop-paging) within the NRU, and the remaining 5 bits are reserved.

[0118] Furthermore, the assistance RS is a reference signal that the access network device configures to one or more terminals in an idle state or an inactive state, and is used to assist the terminal in time-frequency synchronization and AGC adjustment. In order to ensure that the terminal can use these RSs normally, the access network device can indicate to the terminal in advance whether these RSs are still in an available state, that is, the availability of the RSs. Therefore, in addition to the first field, the second field, and the third field, the paging indication can also carry a fourth field, which can be used to indicate the availability of the assistance RS.

[0119] In one example, the length of the fourth field may be equal to the number of auxiliary reference signals or auxiliary reference signal groups configured by the network device, wherein the auxiliary reference signal group may include one or more auxiliary reference signals, and is an auxiliary reference signal group obtained by dividing the auxiliary reference signals configured by the network device according to a preset division granularity. The preset division granularity may be set as required, such as one auxiliary reference signal group may include 4 auxiliary reference signals, or one auxiliary reference signal group may include 3 auxiliary reference signals, etc., without limitation.

[0120] It should be noted that, in this example, the fourth field is information common to R POs, called PO common information. The fourth field is for all terminals corresponding to the R POs. Each terminal corresponding to the R POs can parse the fourth field and determine whether the auxiliary reference signal or auxiliary reference signal group configured by the network device is available based on the information carried in the fourth field.

[0121] For example, if the access network device is configured with a total of 9 RSs, the length of the fourth field can be 9 bits, and these 9 bits correspond one-to-one to the 9 RSs, respectively indicating whether the 9 RSs are available; or, when an auxiliary reference signal group includes 3 auxiliary reference signals and there are 3 auxiliary reference signal groups, the length of the fourth field is 3 bits, and these 3 bits correspond one-to-one to the 3 auxiliary reference signal groups, respectively indicating whether the three auxiliary reference signal groups are available.

[0122] In another example, the length of the fourth field may be equal to the number of auxiliary reference signals or auxiliary reference signal groups associated with the R paging occasions. The description of the auxiliary reference signal group can be referred to above and will not be repeated here.

[0123] Among them, in this example, the fourth field is information common to R POs, called PO common information. The fourth field can be directed to all terminals corresponding to the R POs. Each of all terminals corresponding to the R POs can parse the fourth field and determine the auxiliary reference signal or auxiliary reference signal group associated with the R paging occasions based on the information carried by the fourth field.

[0124] For example, assuming that the access network device is configured with a total of 10 RSs: RS1~RS10, R=3, and the R paging occasions are: PO1~PO3, among which RS1~RS6 are associated with PO1~PO3, then the length of the fourth field can be equal to 6 bits, and these 6 bits correspond one-to-one to the 6 RSs associated with PO1~PO3, indicating whether the 6 RSs associated with the three POs PO1~PO3 are available; or, in the case where an auxiliary reference signal group includes 2 auxiliary reference signals and there are 3 auxiliary reference signal groups, the length of the fourth field is 3 bits, and these 3 bits correspond one-to-one to the three auxiliary reference signal groups, respectively indicating whether the three auxiliary reference signal groups associated with the three POs PO1~PO3 are available.

[0125] In another example, the fourth field includes R subfields, the R subfields correspond to R paging occasions, one subfield can be used to indicate the availability of the auxiliary reference signal associated with the paging occasion corresponding to the subfield, and the length of one subfield can be equal to the number of auxiliary reference signals or auxiliary reference signal groups associated with the paging occasion corresponding to the subfield, that is, the fourth field is divided into subfields corresponding to a single specific paging occasion, and one subfield indicates the availability of the auxiliary reference signal associated with a paging occasion. Therefore, in this example, one subfield carries the information of a specific PO, which is oriented to a single PO and is PO specific information.

[0126] For example, assuming that the access network device is configured with a total of 10 RSs: RS1 to RS10, R = 3, and the R paging occasions are: PO1 to PO3, where RS1 to RS2 are associated with PO1, RS3 to RS4 are associated with PO2, and RS5 to RS6 are associated with PO3, then the fourth field can be divided into 3 subfields, each subfield has a length equal to 2 bits, and each bit indicates an RS, or, in the case where an RS group includes 2 RSs, each subfield has a length equal to 1 bit, and each bit indicates an RS group. These 3 subfields correspond to PO1 to PO3 one by one, such as the first subfield indicates whether the 2 RSs associated with PO1 are available, the second subfield indicates whether the 2 RSs associated with PO2 are available, and the third subfield indicates whether the 2 RSs associated with PO3 are available.

[0127] It should be noted that, in this example, the subfields can be arranged according to the time domain position of the PO associated with the subfield, such as the subfield corresponding to the PO with an earlier time domain position is arranged in front, or the subfield corresponding to the PO with a later time domain position is arranged in front, etc. The subfields can also be arranged in a preset order without restriction.

[0128] Furthermore, in order to facilitate more flexible adjustment of the number of POs indicated by the first field or the length of the first field, the paging indication may also include a fifth field. In one example, the fifth field may be used to directly indicate or indirectly indicate the number of paging occasions indicated by the first field, such as the value of the fifth field may be the number R of paging occasions indicated by the first field, and the number R may be directly determined according to the value of the fifth field, or there is a mapping relationship between the value of the fifth field and the number R, and the number R of paging occasions indicated by the first field may be determined according to the mapping relationship.

[0129] For example, the following Table 1 shows the mapping relationship between the bits carried by the first field and the quantity R. As shown in Table 1, bit 00 corresponds to quantity 2, bit 01 corresponds to quantity 3, bit 10 corresponds to quantity 4, and bit 11 corresponds to quantity 5. Assuming that the fifth field carries bit 10, it can be seen from Table 1 that the number of paging occasions indicated by the fifth field is R=4.

[0130] Table 1

[0131] Bit The value of R 00 2 01 3 10 4 11 5

[0132] In another example, the fifth field may be used to indicate the length of the first field. If, as described above, the first field includes R indication information, and one indication information includes one bit, the length of the first field may be 5 bits, and the value of the fifth field may indicate 5, such as the fifth field may directly carry a numerical value R or carry a binary bit number that has a mapping relationship with R. If, as described above, the first field includes R indication information, and one indication information includes M bits, and the length of the first field is R*M, the value of the fifth field may indicate R*M, such as the fifth field may directly carry a numerical value R*M or carry several binary bits that have a mapping relationship with R*M.

[0133] It should be noted that the fifth field is common information for PO, called PO common information. The fifth field can be directed to all terminals corresponding to R POs. All terminals corresponding to R POs can parse the fifth field and determine the number R of paging opportunities or the length of the indication information corresponding to the R paging opportunities based on the information carried by the fifth field.

[0134] For the rest of the fields in DCI, such as the FDRA field, TDRA field, VRB-to-PRB mapping field, MCS field, and TB scaling field, they are mainly used to indicate the time-frequency resources, transmission parameters, etc. of the PDSCH that schedules the PDSCH carrying the paging message. Since the paging indication is sent in advance of the PO, and the interval between the paging indication and the PDSCH may be long, the access network equipment may not be able to predict / determine in advance what time-frequency resources and transmission parameters to use when actually sending the PDSCH. Therefore, the FDRA field, TDRA field, VRB-to-PRB mapping field, MCS field, and TB scaling field are not suitable for inclusion in the paging indication.

[0135] From the above, it can be seen that the paging indication can be as follows Figure 2 As shown, at least the first field is included, and further the second field, the third field, the fourth field, and the fifth field may be included. At this time, if the length of the paging indication is long enough and there are remaining bits, these remaining bits can be used as padding in the paging indication. Figure 2 As shown, the first field is a PO specific field. The indication information in the first field is for a specific PO. The second field, the third field, and the fifth field are PO common fields, which can be oriented to all terminals corresponding to R POs. These fields are common to the R POs. The fourth field can be a PO common field or a PO specific field.

[0136] It should be noted that Figure 2 The drawings are for illustrative purposes only. Figure 2 In addition to the fields shown, with the development of communication technology, Figure 2 Other fields that can be included in the paging indication may also be included without limitation.

[0137] based on Figure 2 The design shown can not only reduce the energy consumption of the terminal by indicating in advance whether there is paging in the PO, but also indicate multiple POs through one paging indication to achieve the purpose of indicating whether there is paging in multiple POs at one time, and by distinguishing between PO common fields and PO specific fields, the PO common fields can be used as much as possible under the condition of sufficient indication information, thereby saving signaling overhead.

[0138] The following describes how the terminal determines which R POs the first indicated are when the first field indicates whether there is paging within the R POs.

[0139] Mode 1: One paging occasion corresponds to K paging indications, that is, one paging occasion can be indicated by K paging indications.

[0140] Wherein, K is an integer greater than or equal to 1, and K may be pre-configured to the terminal by the access network device or pre-defined by the protocol without limitation. The K paging indications corresponding to the paging opportunity may be the K consecutive paging indications before the paging opportunity and closest to the paging opportunity, and the K paging indications correspond to the K consecutive SSBs closest to the paging opportunity before the paging opportunity, and the paging indication is located near the SSB corresponding to the paging indication. Optionally, the consecutive K SSBs are K SSBs in K consecutive SSB cycles, or SSBs with the same index in K consecutive SSB cycles.

[0141] In the following way, after the terminal calculates its own PO, it can determine the K consecutive SSBs that are located before its own PO and closest to the PO according to the time domain position of the PO and the time domain position of the SSB, and determine the K paging indications near the K SSBs corresponding to the terminal's PO. Further, according to the same method, the terminal can calculate several other POs near its own PO and determine the K paging indications corresponding to each of these POs. The K paging indications corresponding to each of these POs may be the same as the K paging indications corresponding to the terminal's PO. In this way, the terminal can determine which POs are associated with each of the K paging indications corresponding to its own PO.

[0142] Furthermore, after the terminal determines which POs are associated with the paging indication corresponding to its own PO, it can determine which indication information corresponds to its own PO based on the time domain position of these POs and the sorting rule of the indication information in the first field, and then determine whether there is paging in its own PO based on the indication information corresponding to its own PO, and stop working as soon as possible if there is no paging, saving energy consumption.

[0143] From the above process, in method 1, the number of POs corresponding to different paging indications can be the same or different.

[0144] For example, Figure 3aAs shown, assuming that one PO corresponds to 2 paging indications, there are SSB1~SSB5 before PO5, there are SSB1~SSB4 before PO4, there are SSB1~SSB3 before PO3, there are SSB1~SSB3 before PO2, and there is SSB1~SSB2 before PO1, the paging indication corresponding to PO5 can be the two paging indications corresponding to the vicinity of SSB4 and SSB5, the paging indication corresponding to PO4 can be the two paging indications corresponding to the vicinity of SSB4 and SSB3, the paging indication corresponding to PO3 can be the two paging indications corresponding to the vicinity of SSB3 and SSB2, the paging indication corresponding to PO2 can be the two paging indications corresponding to the vicinity of SSB3 and SSB2, and the paging indication corresponding to PO1 can be the two paging indications corresponding to the vicinity of SSB2 and SSB1. It can be seen that the paging indication near SSB4 can correspond to PO4 and PO5, the paging indication near SSB3 can correspond to PO3 and PO2, the paging indication near SSB2 can correspond to PO3, PO2 and PO1, and the paging indication near SSB1 only corresponds to PO1. Assuming that the PO of the terminal is PO2, and PO2 corresponds to the paging indication near SSB2, according to the above method, the terminal can determine that the paging indication corresponding to it also corresponds to PO1 and PO3. According to the time domain position relationship among PO3, PO2 and PO1 and the sorting rules corresponding to the indication information, it is determined that the indication information corresponding to PO2 is the second indication information in the first field.

[0145] Method 2: configure a monitoring time interval before the paging opportunity, so that after the terminal calculates its own paging opportunity, it receives the paging indication corresponding to the paging opportunity within the monitoring time interval corresponding to the paging opportunity, obtains the indication information corresponding to the paging opportunity from the received paging opportunity, and determines whether there is paging in the paging opportunity according to the indication information.

[0146] The monitoring time interval may be configured by the access network device to the terminal. For example, the access network device sends monitoring time window configuration information to the terminal, and the terminal receives the monitoring time window configuration information and determines the monitoring time interval corresponding to the paging opportunity according to the received monitoring time window configuration information.

[0147] Specifically, the monitoring time window configuration information may directly include the monitoring time interval, or the monitoring time window configuration information may include the starting point of the monitoring time interval. In this case, the end point of the monitoring time interval may be set to the starting time of the paging opportunity or a time point before the starting time of the paging opportunity; or, the monitoring time configuration information may include the starting point and end point of the monitoring time interval without restriction.

[0148] In the second method, after the terminal calculates its own PO, it can calculate several other POs near its own PO, and determine the paging indication corresponding to each of these POs. At this time, it is assumed that the paging indication corresponding to the PO is located near the SSB before the PO. Further, it can be determined which paging indications corresponding to other POs near the terminal's PO are also included in the monitoring time interval corresponding to the terminal's PO, and then determine which POs are associated with the paging indications in the monitoring time interval. Further, after determining which POs are associated with the paging indications in the monitoring time interval, it can be determined which indication information corresponds to its own PO based on the time domain positions of these POs and the sorting rules of the indication information in the first field, and then determine whether there is paging in its own PO based on the indication information corresponding to its own PO, and if there is no paging, stop working as soon as possible to save energy consumption.

[0149] From the above process, in the second method, the number of paging occasions corresponding to different paging indications can be the same or different.

[0150] For example, Figure 3b For example, there are SSB1 to SSB5 before PO5, there are SSB1 to SSB4 before PO4, there are SSB1 to SSB3 before PO3, there are SSB1 to SSB3 before PO2, there are SSB1 to SSB2 before PO1, the PO of the terminal is PO2, and the monitoring time interval corresponding to PO2 of the terminal is a time interval from the starting point of SSB1 to the end point of the paging indication near SSB2, and the paging indications near SSB2 and SSB1 are within the monitoring time interval. Further, according to the setting principle that the paging indication corresponding to PO is located near the SSB before the PO, it can be known that the paging indication corresponding to PO3 can be the paging indication near SSB3, SSB2, and SSB1, the paging indication corresponding to PO2 can be the paging indication near SSB3, SSB2, and SSB1, and the paging indication corresponding to PO1 can be the paging indication near SSB2 and SSB1. The paging indication near SSB2 within the monitoring time interval can correspond to PO1, PO2 and PO3, and the paging indication near SSB1 can correspond to PO1, PO2 and PO3. Then, according to the time domain position relationship among PO3, PO2 and PO1 and the sorting rules corresponding to the indication information, the indication information corresponding to PO2 is determined to be the second indication information in the first field.

[0151] Mode 3: The number of paging occasions indicated by one paging indication is configured as R, and the number of paging occasions indicated by different paging indications is the same, that is, R.

[0152] Exemplarily, the R paging occasions corresponding to the paging indication may be the R consecutive paging occasions after the paging occasion, and the first paging occasion of the R paging occasions may be the paging occasion after the paging indication and closest to the paging indication. The value of R may be configured by the access network device to the terminal, or may be pre-defined by the protocol, and is not limited.

[0153] In method three, after setting the paging indication near the SSB, the terminal can know which R PO the paging indication corresponds to, and which R PO corresponding to the paging indication includes the terminal's PO, and then determine which indication information corresponds to its own PO according to the R POs corresponding to the paging indication and the sorting rule of the indication information in the first field, and then determine whether there is paging in its own PO according to the indication information corresponding to its own PO, and stop working as soon as possible if there is no paging, saving energy consumption.

[0154] For example, still Figure 3c For example, assuming R=3, paging indications are set near SSB1~SSB5, the three POs corresponding to the paging indication near SSB1 are PO1~PO3, the three POs corresponding to the paging indication near SSB2 are PO2~PO4, and the three POs corresponding to the paging indication near SSB3 are PO3~PO5. If the PO of the terminal is PO2, the terminal can determine that the paging indication corresponding to PO2 located in SSB1 also indicates PO1 and PO3, and then according to the time domain position relationship among PO3, PO2 and PO1 and the sorting rule corresponding to the indication information, determine that the indication information corresponding to PO2 is the second indication information in the first field.

[0155] As can be seen from the above, if the paging occasions are grouped, such as divided into M MOs, at this time, the M bits included in the indication information corresponding to the paging occasion can be fixed or dynamically adjusted. Under the condition of ensuring that the false alarm probability of the terminal is low, in order not to waste signaling overhead, all bits in the paging indication of fixed length are occupied as much as possible, that is, they are filled with available information. Specifically, this method is shown in Example 1 or Example 2 below:

[0156] Example 1: If there are other fields indicating valid information in addition to the first field in the paging indication, then If the field indicating valid information in the paging indication is only the first field, the value of M is

[0157] A is the length of the paging indication, and B is the length of the field indicating valid information in the paging indication except the first field, such as the total length of the second field, the third field, the fourth field and the fifth field.

[0158] By using the method shown in Example 1, the number of padding bits in the paging indication can be minimized, the number of bits of valid information can be maximized, and the number M of further grouping of paging occasions can be maximized, thereby reducing the probability of false alarm of terminal paging and increasing the probability of successful paging of the terminal.

[0159] Example 2: R paging occasions The indication information corresponding to each paging occasion includes: bits; the indication information corresponding to each paging opportunity in the remaining paging opportunities of R paging opportunities includes bits.

[0160] Wherein, A is the length of the paging indication, and B is the length of the field indicating valid information in the paging indication except the first field, such as the total length of the second field, the third field, the fourth field and the fifth field. It should be noted that if the field indicating valid information in the paging indication is only the first field, the value of B in the formula shown in Example 2 is 0.

[0161] Among them, in Example 2, The indication information corresponding to each paging occasion may be some indication information at the front position, some indication information at the back position, or some indication information at a preset position in the first field, without limitation. For example, taking 10 bits to indicate 4 POs as an example, according to the method shown in Example 2, the number of bits included in the 4 indication information corresponding to the 4 POs may be {3, 3, 2, 2}, or {2, 2, 3, 3} respectively.

[0162] By using the method shown in Example 2, the existence of padding bits can be completely avoided, the number of bits of effective information can be maximized as much as possible, and the number M of further grouping of paging occasions can be as large as possible, thereby reducing the probability of false alarm of terminal paging and increasing the probability of successful paging of the terminal.

[0163] Furthermore, in order to facilitate the terminal to accurately receive the paging indication near the SSB, the paging indication and the synchronization signal block SSB closest to the paging indication are in a quasi-colocated (QCL) relationship; or, the paging indication and the SSB associated with the paging indication are in a QCL relationship. In other words, the terminal device may assume that the paging indication and the synchronization signal block SSB closest to the paging indication have a quasi-colocated relationship. When the paging indication is DCI, the QCL relationship between the paging indication and the SSB can be equivalently described as a QCL relationship between the CORESET associated with the search space where the paging indication is located and the associated (or closest) SSB.

[0164] Among them, the QCL relationship actually characterizes what beam receiving parameters the terminal uses to receive the signal. When two downlink signals are QCL, the terminal can use the same receiving beam to receive the two signals. For example, if the paging indication has a QCL relationship with the synchronization signal block SSB closest to the paging indication, the terminal can use the same receiving beam as the receiving SSB to receive the paging indication. If the paging indication has a QCL relationship with the SSB associated with the paging indication, the terminal can use the same receiving beam as the SSB associated with the paging indication to receive the paging indication.

[0165] Furthermore, in the case where a paging opportunity may be indicated by multiple paging indications, the indication information corresponding to the paging opportunity received by the terminal may be inconsistent, resulting in the terminal being unable to achieve energy saving through paging indications. For example, if the terminal is a terminal with poor coverage, it needs to receive SSB1 and SSB2 for pre-synchronization. If the contents indicated by the paging indications near SSB1 and SSB2 are consistent, the terminal can enter a dormant state to save energy after receiving the paging indication near SSB1 and obtaining an indication that it will not be paged. If the contents indicated by the paging indications near SSB1 and SSB2 are inconsistent, the terminal must receive the paging indication near SSB2 for safety reasons, and no energy saving gain can be obtained.

[0166] In order to avoid the above problem, in the embodiment of the present application, it is also necessary to stipulate that the indication content of the first field in different paging indications for the same paging opportunity is the same, so that the content of the indication information for the same paging opportunity in each paging indication is consistent.

[0167] The following describes the process of network device paging terminal by taking the paging indication as the above design as an example.

[0168] The paging method provided in the embodiment of the present application can be used in any of the fourth generation (4G) system, long term evolution (LTE) system, fifth generation (5G) system, new radio (NR) system, NR-vehicle-to-everything (V2X) system, and Internet of Things system, and can also be applied to other next generation communication systems, etc., without limitation. Figure 4 Taking the communication system shown as an example, the paging method provided in the embodiment of the present application is described.

Figure 4In the system shown, data can be transmitted between the terminal and the network device through the Uu port. For example, the network device can send downlink data to the terminal through the Uu port, and the terminal can send uplink data to the network device through the Uu port. Data can be transmitted between terminals through SL, as described above. Figure 4 The network devices and terminals in the communication device can be referred to as communication devices. Figure 4 is an exemplary framework diagram, Figure 4 The number of nodes included in is unlimited, except Figure 4 In addition to the functional nodes shown, other nodes may also be included, such as core network equipment, gateway equipment, application servers, etc., without limitation.

[0170] Among them, the network device is mainly used to implement functions such as resource scheduling, wireless resource management, and wireless access control of the terminal.

The following takes the terminal as an example to describe the paging method provided in the embodiment of the present application.

[0172] In the specific implementation, Figure 4 The network elements shown, such as terminals and network equipment, can be Figure 5 The structure shown may include Figure 5 Parts shown. Figure 5 A schematic diagram of the composition of a communication device 500 provided in an embodiment of the present application. When the communication device 500 has the functions of the terminal described in the embodiment of the present application, the communication device 500 may be a terminal or a chip or system on chip in the terminal.

[0173] like Figure 5 As shown, the communication device 500 may include a processor 501, a communication line 502, and a communication interface 503. Further, the communication device 500 may also include a memory 504. The processor 501, the memory 504, and the communication interface 503 may be connected via the communication line 502.

The processor 501 may also be other devices with processing functions, such as circuits, devices, or software modules.

[0175] The communication line 502 is used to transmit information between the components included in the communication device 500.

[0176] The communication interface 503 is used to communicate with other devices or other communication networks.

The embodiment of the present application is described by taking the communication interface 503 as a radio frequency module as an example, wherein the radio frequency module may include an antenna, a radio frequency circuit, etc., and the radio frequency circuit may include a radio frequency integrated chip, a power amplifier, etc.

[0177] The memory 504 is used to store instructions, where the instructions may be computer programs.

[0178] Among them, the memory 504 can be a read-only memory (ROM) or other types of static storage devices that can store static information and / or instructions, or a random access memory (RAM) or other types of dynamic storage devices that can store information and / or instructions, or an electrically erasable programmable read-only memory (EEPROM), a compact disc read-only memory (CD-ROM) or other optical disc storage, optical disc storage, magnetic disk storage media or other magnetic storage devices, and the optical disc storage includes a compressed optical disc, a laser disc, an optical disc, a digital versatile disc, a Blu-ray disc, etc.

[0179] It should be noted that the memory 504 can exist independently of the processor 501, or can be integrated with the processor 501. The memory 504 can be used to store instructions or program codes or some data, etc. The memory 504 can be located in the communication device 500, or can be located outside the communication device 500, without limitation. The processor 501 is used to execute the instructions stored in the memory 504 to implement the paging method provided in the following embodiments of the present application.

[0180] In one example, the processor 501 may include one or more CPUs, such as Figure 5 CPU0 and CPU1 in.

[0181] As an optional implementation, the communication device 500 includes multiple processors, for example, Figure 5 In addition to the processor 501, a processor 507 may also be included.

[0184] In the embodiment of the present application, the chip system may be composed of a chip, or may include a chip and other discrete devices.

[0185] Combine the following Figure 4 The communication system shown in the figure takes the paging indication as PO as an example to describe the process of the network device paging the first terminal. In the following embodiments, each device may have Figure 5 The components shown in the figure, and the actions, terms, etc. involved in each embodiment can refer to each other. The message name or parameter name in the message exchanged between the devices in each embodiment is only an example. Other names can also be used in the specific implementation without limitation. For example, the "include" described in this application can be replaced by "include" or "carry". The paging indication described in this application can be replaced by WUS or early paging indication, etc.

[0186] Figure 6 A paging method provided in an embodiment of the present application, such as Figure 6 As shown, the method may include:

[0187] Step 601: The network device determines the paging terminal.

[0188] The network device can be Figure 4 The network devices in the terminal may include Figure 4 One or more terminals in an idle state or an inactive state may include a first terminal, a second terminal, a third terminal, etc. These terminals may correspond to the same PO or different POs without limitation. This embodiment is described by taking these terminals corresponding to the same PO as an example.

[0189] Exemplarily, when the terminal has a downlink service demand, the network device determines to page the terminal, triggering the terminal to switch from an idle state or an inactive state to a connected state, and receive the downlink service in the connected state.

[0190] Step 602: The network device periodically sends one or more SSBs before the PO of the terminal, and sends one or more paging indications near one or more SSBs.

[0191] Among them, the PO of the terminal can be the time interval for the terminal to monitor and schedule the DCI of the PDSCH carrying the paging message. Exemplarily, the network device can determine the PF of the terminal and the PO of the terminal according to the above formula (1) and the above formula (2), which will not be repeated here.

[0192] Among them, SSB can be used for terminal pre-synchronization. The relevant description of SSB is as mentioned above and will not be repeated here.

[0193] Among them, the paging indication can be used to indicate whether there is paging in one or more POs including the PO of the terminal, such as the paging indication can indicate whether there is paging in R POs, where R is an integer greater than or equal to 1. The number of indication information included in the paging indication and the number of bits included in each indication information can refer to the above description, such as one indication information can include one bit or M bits, and the number of bits included in each indication information is the same or different, which will not be repeated.

[0194] Among them, the nearby SSB that sends a paging indication can be located in the same SSB cycle or in different SSB cycles, without limitation. In addition, in the present application, for the convenience of description, the nearby SSB that sends a paging indication can be referred to as an SSB associated / corresponding to the paging indication or an SSB closest to the paging indication, etc., without limitation. Taking the paging indication corresponding to the SSB as an example, one SSB can correspond to one paging indication, that is, one paging indication can be sent near an SSB, and the positional relationship between the SSB and the paging indication near it can be referred to above and will not be repeated.

[0195] Specifically, the design forms of each paging indication can refer to Figure 2 The mapping relationship between paging indications and POs, such as how many POs a paging indication specifically indicates and how many POs a PO specifically corresponds to, etc., can be determined by referring to the above-mentioned method one, method two or method three. For example, a paging indication can indicate R POs, a PO can correspond to K paging indications, or a PO corresponds to a paging indication within a monitoring time interval, etc., which will not be elaborated on.

[0196] Furthermore, in order to avoid inconsistency in the indication information corresponding to the same PO, which results in the terminal being unable to achieve the purpose of energy saving, if the terminal's PO corresponds to multiple paging indications, the indication information used to indicate the terminal's PO in the multiple paging indications is the same, thereby solving the inconsistency in the indication information corresponding to the same PO, ensuring that the terminal is ready to obtain the indication information, and enters the sleep state in advance when the indication is not paged, thereby achieving energy saving.

[0197] Furthermore, in order to improve the accuracy of paging indications sent by network equipment and facilitate the terminal to accurately receive paging indications, a QCL relationship is established between PO and the SSB corresponding to PO, or a QCL relationship is established between PO and the SSB associated with PO. The network equipment can send a paging indication to the terminal according to the transmitting beam of the SSB, and correspondingly, the terminal receives the paging indication according to the receiving beam of the SSB, thereby improving the accuracy of the terminal receiving the paging indication.

[0198] Step 603: The network device sends DCI in the PO of the terminal, where the DCI is used to schedule the PDSCH carrying the paging message.

[0199] Among them, the relevant descriptions of DCI and PDSCH can be referred to above and will not be repeated here.

[0200] Among them, the paging message may include identification information of multiple terminals that need to be paged (such as the first terminal, the second terminal, etc.), and the PO of the terminals that need to be paged is the same. In this way, the purpose of paging multiple terminals through one paging process is achieved, reducing the signaling overhead and energy consumption caused by the interaction between network equipment and terminals.

[0201] Step 604: The terminal receives one or more SSBs and one or more paging indications.

[0202] Exemplarily, the terminal can determine which SSBs need to be received based on the relevant configuration of the SSB, its own coverage and / or its own hardware processing capabilities, and further, based on the above-mentioned method one, method two or method three, the paging indication corresponding to the terminal's PO is located near which SSBs among the SSBs that need to be received, and receive one or more SSBs and one or more paging indications according to the determination result.

[0203] It should be noted that the present application does not limit the execution order of step 603 and step 604, which can be executed simultaneously or in the same order. Figure 6 As shown, step 603 is performed first, and then step 604 is performed, or step 604 is performed first, and then step 603 is performed, etc., without limitation. In addition, it should be noted that in this application, for network equipment and terminals, "the design form of paging indication (such as which fields the paging indication includes, and how many bits each indication information in the paging indication includes)" and "how many POs a paging indication specifically indicates, and how many POs a PO specifically corresponds to" are consistent. The two can pre-determine which design form and which determination method to use, or the network equipment can determine which design form and which determination method to select, and indicate the selection result to the terminal, etc., without limitation.

[0204] Step 605: The terminal determines whether to monitor (or continue to monitor) the DCI in the PO of the terminal according to the first paging indication.

[0205] Among them, the first paging indication can be the first paging indication among one or more paging indications corresponding to the terminal's PO, or can be any paging indication among one or more paging indications corresponding to the terminal's PO, etc., without limitation.

[0206] Exemplarily, the terminal determines whether to monitor (or continue to monitor) the DCI in the terminal's PO based on the first paging indication, which may include: the terminal determines the indication information corresponding to the terminal's PO based on the time domain position of the terminal's PO among R POs, and determines whether to monitor DCI on the terminal's PO based on the indication information corresponding to the terminal's PO. For example, if the indication information corresponding to the terminal's PO is used to indicate that there is paging in the terminal's PO, it is determined to monitor DCI on the terminal's PO; if the indication information corresponding to the PO is used to indicate that there is no paging in the terminal's PO, it is determined not to monitor DCI on the terminal's PO, and the terminal stops working and enters a sleep state to save energy consumption.

[0207] As described above, the R indication information corresponding to the R POs may be arranged in the paging indication according to the time domain positions of the R POs, such as the indication information corresponding to the PO with an earlier time domain position is arranged first in the paging indication, and the indication information corresponding to the PO with a later time domain position is arranged last in the paging indication, or the indication information corresponding to the PO with an earlier time domain position is arranged last in the paging indication, and the indication information corresponding to the PO with a later time domain position is arranged first in the paging indication. The terminal determines the indication information corresponding to the terminal's PO according to the time domain position of the terminal's PO in the R POs, which may include: the terminal determines the indication information corresponding to the terminal's PO according to the sorting rule of the R indication information.

[0208] Furthermore, if the terminal determines to monitor the DCI in the PO of the terminal based on the first paging indication, the terminal continues to be in a working state after receiving the first paging indication and completes pre-synchronization. After pre-synchronization, the terminal monitors the DCI in the PO of the terminal, receives the PDSCH carrying the paging message at the resource position indicated by the DCI, and determines whether it is paged based on the identification information of the terminal carried in the paging message. If it is paged, a random access process is initiated. After the random access is successful, service data is transmitted to and from the network device.

[0209] based on Figure 6 In the method shown, the network device can pre-set a paging indication before PO, and use the paging indication to indicate to the terminal in advance whether there is a paging in PO, so that when there is no paging in PO, the terminal is triggered to stop working in advance and enter a dormant state, so as to reduce the energy consumption of the terminal. Figure 6 The method can also indicate whether there is paging in multiple POs by setting a paging indication, thereby achieving the purpose of indicating whether there is paging in multiple POs at one time and saving signaling overhead.

[0210] The above mainly introduces the solution provided by the embodiment of the present application from the perspective of interaction between each node. It is understandable that each node, such as a terminal, etc., in order to realize the above functions, includes a hardware structure and / or software module corresponding to each function. It should be easily appreciated by those skilled in the art that, in combination with the algorithm steps of each example described in the embodiments disclosed herein, the present application can be implemented in the form of hardware or a combination of hardware and computer software. Whether a function is executed in the form of hardware or computer software driving hardware depends on the specific application and design constraints of the technical solution. Professional and technical personnel can use different methods to implement the described functions for each specific application, but such implementation should not be considered to be beyond the scope of the present application.

[0211] The embodiment of the present application can divide the functional modules of the terminal etc. according to the above method example. For example, each functional module can be divided corresponding to each function, or two or more functions can be integrated into one processing module. The above integrated modules can be implemented in the form of hardware or in the form of software functional modules. It should be noted that the division of modules in the embodiment of the present application is schematic and is only a logical function division. There may be other division methods in actual implementation.

[0212] Figure 7 The structure diagram of a communication device 70 is shown. The communication device 70 may be a first communication device, or a chip in the first communication device, or a system on chip. The communication device 70 may be used to perform the functions of the first communication device involved in the above embodiment. As an implementable manner, Figure 7 The communication device 70 shown includes: a receiving unit 701, a processing unit 702;

[0213] The receiving unit 701 is configured to receive a first paging indication including a first field sent by a network device before a paging opportunity of the terminal, wherein the first field is used to indicate whether to send a paging within R paging opportunities including the paging opportunity of the terminal. For example, the receiving unit 701 can support the communication device 70 to perform step 604.

[0214] The processing unit 702 is configured to determine, according to the first paging occasion, whether to monitor the DCI for scheduling the paging message at the paging occasion of the terminal. For example, the processing unit 702 may support the communication device 70 to perform step 605.

[0215] Specifically, the above Figure 6 All relevant contents of each step involved in the illustrated method embodiment can be referred to the functional description of the corresponding functional module, and will not be repeated here.
