Description

[0001] This invention is a divisional application of the invention application filed on August 6, 2021, with application number 202110901354.3 and title "Paging Processing Method and Apparatus". Technical Field

[0002] This invention relates to the field of communication technology, and in particular to a paging processing method and apparatus. Background Technology

[0003] In related technologies, many user equipment (UEs) monitor the paging downlink control channel (paging PDCCH) on the same paging occupancy (PO). When a UE in the PO is paging, the base station needs to send a paging early indication (PEI), which indicates that a paging PDCCH is present on the PO. At this time, all UEs monitoring the PO will receive both the paging PDCCH and the paging physical downlink shared channel (PDSCH). For UEs that are not paging, they can only determine that there is no paging and enter a low-power or sleep state after receiving both the paging PDCCH and the paging PDSCH, resulting in wasted power.

[0033] Figure 1This diagram illustrates a block diagram of a wireless communication system applicable to embodiments of this application. The wireless communication system includes a terminal 11 and a network device 12. The terminal 11 can also be referred to as a terminal device or user equipment (UE).

The base station is not limited to specific technical terms. It should be noted that in this application embodiment, only the base station in the NR system is used as an example, but the specific type of base station is not limited.

[0034] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0035] like Figure 2 As shown, an embodiment of the present invention provides a paging processing method, including:

[0036] Step 201: The terminal device determines the first information field corresponding to the terminal device in the first downlink control information (DCI) according to the first paging opportunity number. The first DCI contains N1 information fields, and each information field corresponds to one or more paging opportunities. The first paging opportunity number is the number of the paging opportunity monitored by the terminal device in the paging opportunities corresponding to the N1 information fields. N1 is a positive integer, and the paging opportunities corresponding to the first information field include G1 subgroups, where G1 is a positive integer.

[0037] In this step, the first DCI can be an existing DCI format, such as reusing DCI format 2_6, or a newly defined DCI format. The first DCI can indicate the paging status of N1 POs.

[0038] Optionally, before step 201 above, the method further includes:

[0039] Receive the first DCI sent by the network device.

[0040] Step 202: Based on the subgroup number corresponding to the terminal device, determine the first bit corresponding to the terminal device in the first information field, wherein the first bit is used to indicate the paging status of the terminal device.

[0041] Specifically, the first bit is used to indicate whether the terminal device is paging or not. Furthermore, the number of information bits in each information field is the same as the number of subgroups included in the corresponding paging opportunity. The number of information bits in each information field can be the same or different; for example, they can all contain G1 information bits. These G1 information bits can indicate the paging status of the G1 subgroups corresponding to the paging opportunity.

[0042] In this embodiment of the invention, the first DCI carries a PEI, which can indicate the paging status of multiple POs. This PEI supports sub-grouping. For example, if UEs on a PO are divided into n sub-groups, when a UE in a PO is paging, the base station needs to send a PEI to indicate that the sub-group to which that UE belongs is paging. At this time, all UEs in the same sub-group as that UE will receive the paging DCI and paging PDSCH, while UEs in other sub-groups will determine that their sub-group is not paging, and thus, UEs in other sub-groups do not need to receive the paging DCI and paging PDSCH and can directly enter a low-power or sleep state. Therefore, PEI support for sub-grouping can reduce the power consumption of some UEs in a PO.

[0043] In this embodiment of the invention, the terminal device determines the first information field corresponding to the terminal device in the first downlink control information (DCI) based on the first paging opportunity number, and determines the first bit corresponding to the terminal device in the first information field based on the subgroup number corresponding to the terminal device. Then, it can determine whether the terminal device is paging based on the first bit. Thus, in this embodiment of the invention, through the N1 information fields and information bits in the first DCI, it is possible to indicate whether different subgroups of UEs are paging, thereby enabling UEs without paging to directly enter a low-power or sleep state, effectively reducing the terminal's power consumption.

[0044] Optionally, the method in this embodiment of the invention further includes:

[0045] The starting position of the first information field is determined based on the first paging opportunity number and at least one of G1.

[0046] Furthermore, the starting position of the first information field satisfies the following formula:

[0047] Location_start1 = PO_index*G1, or, Location_start1= PO_index*G1+1;

[0048] Where Location_start1 represents the starting position of the first information field, and PO_index represents the first paging opportunity number.

[0049] Optionally, before determining the first information field corresponding to the terminal device in the first downlink control information (DCI) based on the first paging opportunity number, the method further includes:

[0050] The first paging opportunity number is determined based on the paging parameters;

[0051] The paging parameters include at least one of the following: the number of paging frames in a DRX cycle, the number of paging opportunities in a paging frame, the length of the DRX cycle, the index of the paging opportunity in the paging frame, and the SFN where the paging opportunity is located.

[0052] Furthermore, the first paging opportunity number satisfies the following formula:

[0053] PO_Index=(SFN_PF*N*Ns / T+i_s)mod N1;

[0054] Wherein, PO_Index represents the first paging opportunity number, SFN_PF represents the system frame number SFN where the paging frame corresponding to the paging opportunity is located, N represents the number of paging frames in a discontinuous reception DRX cycle, Ns represents the number of paging opportunities in a paging frame, T represents the length of the DRX cycle, and i_s represents the index of the paging opportunity in the paging frame.

[0055] Optionally, each information field corresponds to one paging opportunity, and the first information field includes G1 information bits, each information bit corresponding to a subgroup.

[0056] As a first optional implementation, the first information field further includes X1 indicator bits, which are used to indicate relevant information about paging opportunities, where X1 is a positive integer.

[0057] In this implementation, each information field, in addition to containing G1 (the number of subgroups contained in the paging opportunity corresponding to this information field) information bits, may also include X1 indicator bits, through which relevant information of the paging opportunity can be indicated.

[0058] The relevant information for this paging opportunity includes one or more of the following:

[0059] Availability of the tracking reference signal TRS;

[0060] Does the Earthquake and Tsunami Warning System (ETWS) send notification information?

[0061] System message update instruction: Send or not?

[0062] Indication information for the beam tracking the reference signal.

[0063] Optionally, this implementation also includes:

[0064] The starting position of the first information field is determined based on at least one of the first paging opportunity number, G1, and X1.

[0065] Furthermore, the starting position of the first information field satisfies the following formula:

[0066] Location_start1 = PO_index*(G1+X1), or, Location_start1= PO_index*(G1+X1)+1;

[0067] Where Location_start1 represents the starting position of the first information field, and PO_index represents the first paging opportunity number.

[0068] As a second alternative implementation, the first DCI further includes an indication field for indicating relevant information about paging opportunities.

[0069] In this implementation, the first DCI, in addition to including the aforementioned N1 information fields, also includes an indication field, which is used to indicate relevant information about the paging opportunity. The relevant information about the paging opportunity includes one or more of the following:

[0070] Availability of the tracking reference signal TRS;

[0071] Does the Earthquake and Tsunami Warning System (ETWS) send notification information?

[0072] System message update instruction: Send or not?

[0073] Indication information for the beam tracking the reference signal.

[0074] Optionally, in the first embodiment of this implementation, the aforementioned indication field is located after N1 information fields.

[0075] Optionally, the first embodiment further includes:

[0076] The starting position of the first information field is determined based on the first paging opportunity number and at least one of G1.

[0077] Furthermore, the starting position of the first information field satisfies the following formula:

[0078] Location_start1 = PO_index*G1, or, Location_start1= PO_index*G1+1;

[0079] Where Location_start1 represents the starting position of the first information field, and PO_index represents the first paging opportunity number.

[0080] Optionally, the first embodiment further includes:

[0081] The starting position of the indication field is determined based on at least one of N1 and G1.

[0082] Furthermore, the starting position of the indicator field satisfies the following formula:

[0083] Location_start2 = N1*G1, or Location_start2 = N1*G1+1;

[0084] Location_start2 indicates the starting position of the field.

[0085] Optionally, in a second embodiment of this implementation, the indication field is located before the N1 information fields.

[0086] The second embodiment also includes:

[0087] The starting position of the first information field is determined based on at least one of the first paging opportunity number, G1, and X1.

[0088] Furthermore, the starting position of the first information field satisfies the following formula:

[0089] Location_start1 = PO_index*G1+X1;

[0090] Alternatively, Location_start1 = PO_index * G1 + X1 + 1;

[0091] Where Location_start1 represents the starting position of the first information field, and PO_index represents the first paging opportunity number.

[0092] Optionally, in this second embodiment, the starting position of the indication field is the first bit of the first DCI.

[0093] The paging processing method of the present invention will be described below with reference to specific embodiments.

[0094] Example 1:

[0095] Step 1: The terminal device determines the first information field corresponding to the terminal device in the first DCI according to the paging opportunity number, wherein the first DCI includes at least one information field;

[0096] The first DCI can be an existing DCI format or a newly defined DCI format. For example, DCIformat 2_6 can be reused. The first DCI includes at least one information field. For example, the first DCI includes N1 information fields, each information field corresponding to a PO, that is, the first DCI can indicate the paging status of N1 POs.

[0097] The terminal device determines the paging opportunity number (first paging opportunity number) among the N1 paging opportunities it is monitoring, and determines the corresponding information field in the N1 information fields of the first DCI based on the subgroup number corresponding to the terminal device. For example... Figure 3As shown, assuming one DCI-based PEI corresponds to four POPs (i.e., N1=4), the first DCI includes four information fields: information fields 1, 2, 3, and 4. First, the UE determines its paging opportunity number among the four paging opportunities. For example, a UE listening to PO1 determines its paging opportunity number (PO_index) as 0, a UE listening to PO2 determines its paging opportunity number (PO_index) as 1, and so on. Then, the terminal device can determine its corresponding information field among the N1 information fields based on the paging opportunity number. For example, a UE listening to PO1 corresponds to information field 1, a UE listening to PO2 corresponds to information field 2, and so on.

[0098] The paging opportunity number corresponding to the terminal device satisfies the following formula:

[0099] PO_Index = (SFN_PF * N * Ns / T + i_s) mod N1. This formula has been explained in detail above and will not be repeated here.

[0100] The following tables 1 and 2 illustrate the correspondence between PO_Index and the various parameters. Table 1 represents the case of dense PO, and Table 2 represents the case of sparse PO.

[0101] Table 1

[0102]

[0103] Table 2

[0104]

[0105] Using the above calculation formula, the UE can determine the PO_index, which in turn determines the corresponding information field among the N1 information fields in the first DCI. For example, there is a one-to-one correspondence between the PO_index and the information field index; the indices of the N1 information fields in the first DCI are 0, ..., N1-1. The value of the PO_index calculated by the UE is the value of the index of its corresponding information field.

[0106] Step 2: Based on the subgroup number corresponding to the terminal device, determine the first bit corresponding to the terminal device in the first information field. The first bit is used to indicate the paging status of the terminal device.

[0107] The aforementioned subgroup number can also be described as an initial subgroup number, which can be represented by "initial sub-group number" or "sub-group_init". In this embodiment of the invention, a UE on a PO is divided into n sub-groups, each sub-group corresponding to a sub-group number. The aforementioned initial sub-group number is the sub-group number corresponding to the terminal device. The method for the terminal device to determine the initial subgroup number may include: the core network or network equipment providing the terminal device with specific initial subgroup number information; when the core network or network equipment does not provide the terminal device with specific initial subgroup number information, the terminal device may calculate the initial subgroup number information based on paging parameters N, Ns, and UE_ID. This embodiment of the invention does not limit how the terminal device determines the initial subgroup number.

[0108] In the first DCI, different information fields in the N1 information fields correspond to different paging opportunities. The number of bits in each information field is the same as the number of sub-groups in the corresponding paging opportunity. Preferably, different paging opportunities contain the same number of sub-groups. Of course, the number of sub-groups in different paging opportunities can also be different, and this embodiment of the invention does not specifically limit this. Assuming that one DCI-based PEI corresponds to N1 POs, the first DCI contains N1 information fields, and each PO contains G1 sub-groups, that is, each information field contains G1 bits. The terminal device determines the first bit corresponding to the first information field according to the initial sub-group number. For example, if N1=4 and G1=8, the first information field corresponding to the terminal device contains 8 bits, numbered 0, 1, ..., 7. The first bit corresponding to the terminal device in the first information field is the bit corresponding to the initial sub-group number. For example, if the initial sub-group number is 0, it corresponds to the bit with bit number 0 in the first information field.

[0109] Alternatively, each information field, in addition to the G1 bits corresponding to the G1 subgroups of each PO, may also include X1 bits. These X1 bits are used for PO-level information indication, such as indicating TRS availability, whether ETWS is being sent, whether system message update indication is being sent, and beam indication information for the reference signal of time-frequency channel tracking. The TRS availability refers to whether the UE in RRC_IDLE state can use TRS for time-frequency tracking.

[0110] Additionally, the first bit used to indicate the paging status of the terminal device includes: the first bit indicating whether the terminal device is paging or not, that is, regardless of whether the terminal device is paging or not, the network device needs to send a first DCI containing the first bit; or, the first bit indicating that the terminal device is paging, that is, the network device sends a first DCI containing the first bit only when the terminal device is paging; or, the first bit indicating that the terminal device is not paging, that is, the network device sends a first DCI containing the first bit only when the network device is not paging.

[0111] In this embodiment of the invention, it is also necessary to determine the starting position of the first information field. Specifically, assuming that 1 PEI corresponds to N1 POs and 1 PO corresponds to G1 sub-groups, the parameters N1 and G1 are SIB-X notifications broadcast by the base station. The first DCI includes N1 information fields, assuming N1=4, such as... Figure 3 As shown. Assume this DCI-based PEI only includes sub-group indicators and no other information indicators (i.e., only the aforementioned information bits). For a UE in RRC_IDLE state, assuming each information field has the same number of bits (e.g., each information field includes G1 bits), the starting position of each information field and the corresponding bits for different sub-groups in each information field within each PO can be calculated. For example, the starting position of each information field can be determined using the following formula: Location_start1 = PO_index * G1, or Location_start1 = PO_index * G1 + 1.

[0112] Optionally, if the bits in the first DCI are numbered starting from 0, then the formula for determining the starting position of each information field is: Location_start1 = PO_index * G1; if the bits in the first DCI are numbered starting from 1, then the formula for determining the starting position of each information field is: Location_start1 = PO_index * G1 + 1. Location_start1 is the starting position of the first information field in the first DCI, that is, the bit position in the first DCI. The relationship between the starting position of the first information field and G1 and PO_index is shown in Table 3.

[0113] Table 3

[0114]

[0115] Furthermore, the bit positions of different subgroups of different POs in this first DCI satisfy the following formula:

[0116] Location_bit = PO_index*G1 + sub-group_init.

[0117] Step 3: The terminal device receives the first DCI.

[0118] Step 3 can be performed before steps 1 and 2 above.

[0119] Example 2:

[0120] Step 1: The terminal device determines the first information field corresponding to the terminal device in the first DCI according to the paging opportunity number. The first DCI includes at least one information field.

[0121] Step 1 is the same as step 1 in Example 1, and will not be repeated here.

[0122] Step 2: Based on the subgroup number corresponding to the terminal device, determine the first bit corresponding to the terminal device in the first information field. The first bit is used to indicate the paging status of the terminal device.

[0123] The method for determining the subgroup number corresponding to the terminal device has been described in detail in Embodiment 1, and will not be repeated here.

[0124] In this embodiment, the first DCI includes N1 information fields and an indication field. Different information fields within the N1 information fields correspond to different paging opportunities. The number of bits in each information field is the same as the number of sub-groups in the corresponding paging opportunity. Preferably, different paging opportunities have the same number of sub-groups. Of course, different paging opportunities may have different numbers of sub-groups, and this embodiment of the invention does not specifically limit this. The indication field is used to indicate relevant information about the paging opportunity. This indication field may include X1 bits. These X1 bits consist of at least one of M1, M2, M3, and M4 bits, where M1 bits indicate TRS availability, M2 bits indicate whether ETWS sends notification information, M3 bits indicate whether system message update indication is sent, and M4 bits indicate the indication information of the tracking reference signal beam.

[0125] Assuming one DCI-based PEI corresponds to N1 POs, the first DCI contains N1 information fields. Each PO contains G1 subgroups, meaning each information field contains G1 bits. The terminal device determines the first bit in the first information field based on the initial subgroup number. For example, if N1=4 and G1=8, the first information field corresponding to the terminal device contains 8 bits, numbered 0, 1, ..., 7. The first bit in the first information field corresponding to the terminal device is the bit corresponding to the initial subgroup number. For example, if the initial subgroup number is 0, it corresponds to the bit with bit number 0 in the first information field.

[0126] In this embodiment of the invention, it is also necessary to determine the starting position of the first information field. Assume that N1 information fields are located before the first DCI, and the indicator field is located after the first DCI, such as... Figure 4 As shown. Assume that 1 PEI corresponds to N1 POs, and 1 PO corresponds to G1 sub-groups. The parameters N1 and G1 are SIB-X notifications broadcast by the base station. The first DCI includes N1 information fields and 1 indication field. Assume that N1 is 4.

[0127] Different POs are identified by their corresponding information fields through PO_index, such as Figure 4 As shown, PO1 corresponds to information field 1, PO2 corresponds to information field 2, PO3 corresponds to information field 3, and PO4 corresponds to information field 4. The indication field (or other indication field) occupies X1 bits.

[0128] The starting positions of information fields 1-4 can be determined by the following formulas: Location_start1 = PO_index*G1, or Location_start1 = PO_index*G1+1. The starting position of the indicator field is determined by the formula: Location_start2 = N1*G1, or Location_start2 = N1*G1+1.

[0129] Step 3: The terminal device receives the first DCI.

[0130] Step 3 can be performed before steps 1 and 2 above.

[0131] Example 3: Step 1: The terminal device determines the first information field corresponding to the terminal device in the first DCI according to the paging opportunity number. The first DCI includes at least one information field.

[0132] Step 1 is the same as step 1 in Example 1, and will not be repeated here.

[0133] Step 2: Based on the subgroup number corresponding to the terminal device, determine the first bit corresponding to the terminal device in the first information field. The first bit is used to indicate the paging status of the terminal device.

[0134] The method for determining the subgroup number corresponding to the terminal device has been described in detail in Embodiment 1, and will not be repeated here.

[0135] In this embodiment, the first DCI includes N1 information fields and an indication field. Different information fields within the N1 information fields correspond to different paging opportunities. The number of bits in each information field is the same as the number of sub-groups in the corresponding paging opportunity. Preferably, different paging opportunities have the same number of sub-groups. Of course, different paging opportunities may have different numbers of sub-groups, and this embodiment of the invention does not specifically limit this. The indication field is used to indicate relevant information about the paging opportunity. This indication field may include X1 bits. These X1 bits consist of at least one of M1, M2, M3, and M4 bits, where M1 bits indicate TRS availability, M2 bits indicate whether ETWS sends notification information, M3 bits indicate whether system message update indication is sent, and M4 bits indicate the indication information of the tracking reference signal beam.

[0136] Assuming one DCI-based PEI corresponds to N1 POs, the first DCI contains N1 information fields. Each PO contains G1 subgroups, meaning each information field contains G1 bits. The terminal device determines the first bit in the first information field based on the initial subgroup number. For example, if N1=4 and G1=8, the first information field corresponding to the terminal device contains 8 bits, numbered 0, 1, ..., 7. The first bit in the first information field corresponding to the terminal device is the bit corresponding to the initial subgroup number. For example, if the initial subgroup number is 0, it corresponds to the bit with bit number 0 in the first information field.

[0137] In this embodiment of the invention, it is also necessary to determine the starting position of the first information field. Assuming the indicator field is located before the first DCI, and the N1 information fields are located after the first DCI, as follows... Figure 5 As shown. Assume that 1 PEI corresponds to N1 POs, and 1 PO corresponds to G1 sub-groups. The parameters N1 and G1 are SIB-X notifications broadcast by the base station. The first DCI includes N1 information fields and 1 indication field. Assume that N1 is 4.

[0138] Different POs are identified by their corresponding information fields through PO_index, such as Figure 5As shown, PO1 corresponds to information field 1, PO2 corresponds to information field 2, PO3 corresponds to information field 3, and PO4 corresponds to information field 4. The indication field (or other indication field) occupies X1 bits.

[0139] The starting positions of information fields 1-4 can be determined by the following formula: Location_start1 = PO_index*G1+X1; or, Location_start1 = PO_index*G1+X1+1. The starting position of the indicator field is the first bit of the first DCI, which can be numbered starting from 0 or 1.

[0140] In this embodiment of the invention, the terminal device determines the first information field corresponding to the terminal device in the first downlink control information (DCI) based on the first paging opportunity number, and determines the first bit corresponding to the terminal device in the first information field based on the subgroup number corresponding to the terminal device. Then, based on the first bit, it can determine whether the terminal device is paging-enabled. Thus, in this embodiment of the invention, the N1 information fields and G1 information bits in the first DCI can indicate whether different subgroups of UEs are paging-enabled, allowing UEs without paging to directly enter a low-power or sleep state, effectively reducing the terminal's power consumption.

[0141] like Figure 6 As shown, this embodiment of the invention also provides a paging processing method, including:

[0142] Step 601: The network device determines the first information field corresponding to the terminal device in the first downlink control information (DCI) based on the first paging opportunity number. The first DCI contains N1 information fields, and each information field corresponds to one or more paging opportunities. The first paging opportunity number is the number of the paging opportunity that the terminal device is listening to in the paging opportunities corresponding to the N1 information fields. N1 is a positive integer, and the paging opportunities corresponding to the first information field include G1 subgroups, where G1 is a positive integer.

[0143] In this step, the first DCI can be an existing DCI format or a newly defined DCI format, such as reusing DCI format 2_6. The first DCI can indicate the paging status of N1 POs.

[0144] Step 602: The network device determines the first bit corresponding to the terminal device in the first information field according to the subgroup number corresponding to the terminal device, wherein the first bit is used to indicate the paging status of the terminal device.

[0145] Specifically, the first bit is used to indicate whether the terminal device is paging or not. Furthermore, the number of information bits in each information field is the same as the number of subgroups included in the corresponding paging opportunity. The number of information bits in each information field can be the same or different; for example, they can all contain G1 information bits. These G1 information bits can indicate the paging status of the G1 subgroups corresponding to the paging opportunity.

[0146] Optionally, after step 602 above, the method further includes:

[0147] The first DCI is sent to the terminal.

[0148] In this embodiment of the invention, the first DCI carries a PEI, which can indicate the paging status of multiple POs. This PEI supports sub-grouping. For example, if UEs on a PO are divided into n sub-groups, when a UE in a PO is paging, the base station needs to send a PEI to indicate that the sub-group to which that UE belongs is paging. At this time, all UEs in the same sub-group as that UE will receive the paging DCI and paging PDSCH, while UEs in other sub-groups will determine that their sub-group is not paging, and thus, UEs in other sub-groups do not need to receive the paging DCI and paging PDSCH and can directly enter a low-power or sleep state. Therefore, PEI support for sub-grouping can reduce the power consumption of some UEs in a PO.

[0149] In the paging processing method of this invention, the network device determines the first information field corresponding to the terminal device in the first downlink control information (DCI) based on the first paging opportunity number, and determines the first bit corresponding to the terminal device in the first information field based on the subgroup number corresponding to the terminal device. Then, it can determine whether the terminal device is paging based on the first bit. Thus, in this embodiment of the invention, the N1 information fields and information bits in the first DCI can indicate whether different subgroups of UEs are paging, allowing UEs without paging to directly enter a low-power or sleep state, effectively reducing the terminal's power consumption.

[0164] The relevant information for this paging opportunity includes one or more of the following:

[0173] Where Location_start1 represents the starting position of the first information field, and PO_index represents the first paging opportunity number.

[0174] As a second alternative implementation, the first DCI further includes an indication field for indicating relevant information about paging opportunities.

[0198] Optionally, in this second embodiment, the starting position of the indication field is the first bit of the first DCI.

[0199] In the paging processing method of this invention, the network device determines the first information field corresponding to the terminal device in the first downlink control information (DCI) based on the first paging opportunity number, and determines the first bit corresponding to the terminal device in the first information field based on the subgroup number corresponding to the terminal device. Then, it can determine whether the terminal device is paging based on the first bit. Thus, in this embodiment of the invention, the N1 information fields and G1 information bits in the first DCI can indicate whether different subgroups of UEs are paging, allowing UEs without paging to directly enter a low-power or sleep state, effectively reducing the terminal's power consumption.
