Description

Technical Field

[0001] This application belongs to the field of communication technologies, and particularly relates to a communication method, a terminal, and a network-side device. Background Art

[0002] When a terminal is in the idle state or the inactive state, the network cannot know the specific cell where the terminal is located, and can only know the approximate range where the terminal is located. Therefore, when there is a service arrival or for other reasons the terminal needs to enter the connected state, it is necessary to notify the terminal through a paging mechanism and trigger the terminal to enter the connected state through a Random Access Channel (RACH).

[0003] The principle of the paging mechanism is to use the Physical Downlink Shared Channel (PDSCH) indicated by the Physical Downlink Control Channel (PDCCH) to carry the paging message transmitted from above. The terminal device detects the PDCCH in specific time-frequency resources to receive its own paging message. Therefore, the terminal device first needs to calculate the possible paging occasion (PO) and paging frame (PF) for paging, and then detect the PDCCH of the corresponding subframe to obtain the paging message. The terminal device determines whether the paging message is for itself according to the terminal device identifier carried in the paging message.

[0004] In the related art, it is supported to evenly distribute all terminal devices in the idle / inactive state in each PO of each PF within a Discontinuous Reception (DRX) cycle. Under this paging mechanism, the network will page a specific terminal device under each PO, so a large amount of signaling overhead will be generated and the paging duration is relatively long, which is not conducive to power saving on the network side.

As long as the same technical effect is achieved, the base station is not limited to specific technical terms. It should be noted that in the embodiments of this application, only the base station in the NR system is taken as an example for introduction, and the specific type of the base station is not limited.

[0063] For better understanding of the embodiments of this application, the paging mechanism involved in this application is introduced.

[0064] When the terminal is in the idle state or inactive state, the network cannot know the specific cell where the terminal is located and can only know the general range where the terminal is located. Therefore, when there is traffic arriving or for other reasons the terminal needs to enter the connected state, the paging mechanism is required to notify the terminal and trigger the terminal to enter the connected state through the Random Access Channel (RACH).

[0065] The principle of the paging mechanism is to use the Physical Downlink Shared Channel (PDSCH) indicated by the Physical Downlink Control Channel (PDCCH) to carry the paging message transmitted from the upper layer. The terminal device detects the PDCCH on specific time-frequency resources and receives its own paging message. Therefore, the terminal device first needs to calculate the paging occasion (PO) and paging frame (PF) where paging may occur, and then detect the PDCCH of the corresponding subframe. If the terminal device finds a paging Radio Network Temporary Identifier (P-RNTI), it obtains the paging message from the corresponding PDSCH according to the resource block (RB) allocation and modulation coding format indicated by the PDCCH. The terminal device determines whether the paging message is for itself based on the terminal device identifier (ID) carried in the paging message.

[0066] In the related art, the terminal device calculates the PF and PO according to the configuration information of the network.

[0067] The calculation formula of PF is as follows:

[0068] (SFN + PF_offset) mod T = (T div N) * (UE_ID mod N)

[0069] The calculation formula of PO is as follows:

[0070] i_s = floor(UE_ID / N) mod Ns

[0071] Where, T is the DRX cycle of the terminal device;

[0072] N is the total number of PFs within the DRX cycle T, and the network can be configured as oneT, halfT, quarterT, oneEighthT, and oneSixteenthT;

[0073] PF_offset is the offset of the PF position;

[0074] UE_ID is the terminal device identifier, which is 5G-S-TMSI mod 1024, or 0 (when the terminal device does not have 5G-S-TMSI mod 1024);

[0075] Ns is the number of POs within one PF, and the network can be configured as 1, 2, 4.

[0076] Among them, the effect achieved by the calculation formula of the above PF is to evenly distribute the terminal devices with different terminal device identifiers into N PFs, and the N PFs are also evenly distributed within the DRX cycle T; the effect achieved by the calculation formula of the above PO is to evenly distribute the terminal devices with different terminal device identifiers into the POs of different PFs.

[0077] To facilitate a better understanding of the embodiments of the present application, the relevant content of the paging early indication (PEI) in the NR system will be introduced.

[0078] Since multiple terminal devices are associated with one PO, a terminal device may be woken up by mistake to monitor the paging PDCCH and paging PDSCH because other terminal devices in the same group are paged. It will not go to sleep until it is confirmed that the paging PDSCH does not have the terminal device identifier of this terminal device. Therefore, since the terminal device monitors the paging PDCCH / PDSCH in each paging cycle, and since there are multiple associated terminal devices in a PO group, the terminal device may be woken up by mistake, resulting in unnecessary listening power consumption of the terminal device.

[0079] To reduce the power consumption of the terminal device, R17 standard further introduces PEI based on PDCCH (PDCCH-based). The terminal device first receives the PEI before receiving the paging PDCCH, and determines whether it needs to monitor the subsequent paging PDCCH according to the content indicated in the PEI. If the PEI indicates that the terminal device does not receive the paging PDCCH, the terminal device does not need to detect one or more SSBs between the PEI and the PO subsequently, thereby achieving power saving.

[0080] In addition, the PEI also has the function of further grouping and indicating multiple terminal devices of a PO. For example, the PEI is associated with and indicates a PO, and 8-bit information is carried in the PEI for further grouping and indicating multiple terminal devices of the PO. Exemplarily, each bit can correspond to a subgroup, that is, the 8 bits can indicate whether 8 subgroups need to monitor the subsequent paging PDCCH. Based on this, the terminal devices associated in a PO can be further divided into 8 subgroups, and PEI indication is performed for each subgroup, which can reduce the probability of the terminal device being woken up by mistake, thereby reducing the paging listening power consumption of the terminal device.

[0081] Therefore, by introducing the PEI mechanism, the network side can associate the PEI occasion (PEI-O) with the PO of the terminal device, and thus can achieve the purpose of controlling whether to monitor the PO through PEI. When the terminal device receives a PEI indicating that there is a paging message to receive in the subgroup to which it belongs, the terminal device will listen for the paging message in the associated PO, otherwise the terminal device can continue to sleep to achieve energy saving.

[0082] Specifically, the terminal device listens for one PEI-O in each DRX cycle, and one PEI-O includes a set of PDCCH monitoring occasions. Among them, the time domain starting position of the PEI-O is determined by a reference point and an offset. The reference point refers to the starting position of the reference frame, which is determined by the starting frame of the first PF in the PF associated with the PEI-O (indicated by pei-FrameOffset in SIB1). The offset is the symbol-level offset from the reference point to the start of the first PDCCH monitoring occasion of the PEI-O (indicated by firstPDCCH-MonitoringOccasionOfPEI-O in SIB1).

[0083] The downlink control information (DCI) that the terminal device specifically listens for in the PEI-O is DCI 2_7. In other words, DCI 2_7 is used to send PEI to a group of terminal devices. The paging indication field of DCI 2_7 contains bits, where is configured by the RRC layer parameter po-NumPerPEI, indicating the number of corresponding POs in one PEI-O, is configured by the RRC layer parameter subgroupsNumPerPO, indicating the number of corresponding subgroups in one PO. As Figure 2 shown, the number of POs corresponding to one PEI-O is 4, and each PO corresponds to bits, and each bit is used to indicate whether the corresponding subgroup needs to monitor the corresponding PO. The terminal device needs to determine the (i PO ·K + i SG ) bit in the paging indication field, where corresponds to a paging occasion index; K represents the number of bits included in one PO; i SGIndicates the subgroup where the terminal device is located. When the bit value corresponding to the paging indication field = 1, the terminal device needs to listen to the associated paging occasion, otherwise it does not need to listen to the corresponding paging occasion.

[0084] In addition, PEI also defines two grouping methods. One is the grouping method based on the terminal device identifier (such as UE_IDbasedsubgrouping), and the other is the grouping method based on CN assignment (CNassignedsubgrouping).

[0085] In the grouping method based on the terminal device identifier, the access network device can group multiple terminal devices. This grouping method can also be called the grouping method controlled by the access network device. Optionally, the access network device can group according to the identifiers of each terminal device. Specifically, the access network device can calculate the subgroup identifier ID (such as the group number) corresponding to each terminal device based on the identifier of each terminal device. For example, the identifier of the terminal device can be modulo-operated with the number of subgroups. Each terminal device can also obtain its own subgroup ID according to the same calculation method as the access network device. Optionally, the terminal device can default to support the grouping method based on the terminal device identifier.

[0086] In the grouping method based on CN assignment, the core network device can group multiple terminal devices corresponding to a PO. The core network device can notify (such as through NAS signaling) the subgroup ID to which each terminal device belongs to each terminal device, and each terminal device can save the subgroup ID assigned by the core network device for itself.

[0087] If the terminal device is not configured with a subgroup ID based on CN assignment, or if it is configured with a subgroup ID based on CN assignment, but the terminal device is in a cell that only supports subgroups based on UE_ID, then the subgroup ID of the terminal device is determined by the following formula:

[0088] SubgroupID = (floor(UE_ID / (N*Ns)) mod subgroupsNumForUEID)+(subgroupsNumPerPO - subgroupsNumForUEID)

[0089] where N is the total number of PFs within the DRX cycle R, and the network can be configured as oneT, halfT, quarterT, oneEighthT, and oneSixteenthT;

[0090] PF_offset is the offset of the PF position;

[0091] The UE_ID is the identifier of the terminal device, which is 5G-S-TMSImodX. If enhanced DRX (eDRX) is applied, then X takes 32768; otherwise, X takes 8192.

[0092] Ns is the number of POs within a PF, and the network can be configured as 1, 2, or 4.

[0093] subgroupsNumForUEID: The number of subgroups grouped based on UE_ID in a PO, which is broadcast in the system message.

[0094] In the related art, it is supported to evenly distribute all idle / inactive terminals within each PO of each PF in the Discontinuous Reception (DRX) cycle. Under this paging mechanism, the network will page specific terminals under each PO, so a large amount of signaling overhead will be generated and the paging duration is relatively long, which is not conducive to power saving on the network side.

[0095] In view of this, the embodiments of the present application provide a communication method, a terminal, and a network-side device. By indicating to the terminal the paging occasion PO that needs to be monitored, or the PO that the terminal needs to monitor as pre-defined by the protocol, the terminal can perform message monitoring on the specified PO that needs to be monitored, rather than monitoring messages on the evenly distributed POs. Therefore, by controlling the terminal to monitor messages under the specified PO, it is beneficial for the network-side device to page specific terminals under the specified PO, thereby facilitating the reduction of signaling overhead and the reduction of the paging duration on the network side, which is beneficial for power saving on the network side.

[0096] Next, in conjunction with the accompanying drawings, the communication method provided by the embodiments of the present application will be described in detail through some embodiments and their application scenarios.

[0097] Figure 3 The interaction schematic diagram of a communication method provided by the embodiments of the present application is shown. As Figure 3 shown, this communication method at least includes the following steps 310 and 320:

[0098] 310, The terminal obtains first information, and the first information is used to indicate the paging occasion PO that needs to be monitored.

[0099] Specifically, the terminal can obtain the first information from the network-side device, and the first information is used to indicate the PO that the terminal needs to monitor. For example, the network-side device can send the first information to the terminal, and the corresponding terminal receives the first information.

[0100] Exemplarily, the PO that the terminal needs to monitor, that is, the PO that the terminal actually needs to monitor, may refer to the PO in the PF that the terminal needs to monitor. As an implementable manner, the first information may indicate the PF that needs to be monitored and the PO in the PF. As an implementable manner, when it is predefined or configured to monitor a PO in a PF, the first information may indicate the PF that needs to be monitored. Another implementation manner may be that the first indication information respectively indicates the PF index and the PO index. For example, it may directly instruct the terminal to monitor the paging message at the position of the first PO in the first PF associated with the terminal.

[0101] In some embodiments, the first information may indicate the PO index that the terminal needs to monitor, and this PO index may directly match the PO index calculated by the terminal based on the paging configuration. For example, currently the terminal is associated with a PF, and the associated PF contains 4 POs. These four POs may be i_s = 0 (the first PO), i_s = 1 (the second PO), i_s = 2 (the third PO), and i_s = 3 (the fourth PO). When the first information indicates that the terminal needs to monitor the second PO, the terminal can directly find the position of the PO to be monitored according to i_s = 1. Another way may be that when the first information is associated with multiple PFs, the indicated PO index needs to be further converted to obtain the PO index to be monitored. For example, the terminal calculates according to the paging configuration that a DRX cycle contains 2 PFs in total, and each PF contains 4 POs. The first information indicates that the terminal needs to monitor the 5th PO. Then the position of the 5th PO is the PO position of i_s = 0 in the second PF. That is to say, the terminal needs to first determine in which PF and then further determine the PO index to be monitored.

[0102] In some embodiments, step 510 may be specifically implemented as:

[0103] The terminal receives the first indication information from the network device, and this first indication information is used to indicate the position of the PO that the terminal needs to monitor among at least one first PO associated with the first indication information.

[0104] Specifically, the network device may send the first indication information to the terminal, which is used to indicate the position of the PO that the terminal needs to monitor among at least one first PO associated with the first indication information. Correspondingly, the terminal receives this first indication information. At this time, the first indication information is an example of the first information.

[0105] Among them, the at least one first PO associated with the first indication information refers to at least one PO that may need to be monitored by the terminal. Specifically, the first indication information may be associated with a PF, and further may be expressed as being associated with at least one PO in this PF. Or, the first indication information may be associated with two or more PFs, and further may be expressed as being associated with at least one PO in these PFs. Or, the first indication information may be associated with all PFs or all POs. That is to say, the first PO may be a set of all PF or PO positions calculated by all terminals according to the paging configuration. Associating one or more PFs or POs may be based on network configuration or protocol agreement, which is not limited here.

[0106] Therefore, by sending the first indication information to the terminal in the embodiment of the present application, it is possible to specify the position of the PO that the terminal needs to monitor among the at least one first POs that may need to be monitored, that is, all PO positions calculated by all terminals according to the paging configuration, so as to control the terminal to monitor messages under the specified (or specific) PO.

[0107] Among them, the at least one first PO associated with the first indication information may be a PO in a PF, or may be a PO in two or more PFs, which is not limited in the present application.

[0108] In some embodiments, the first indication information may be implemented in the following three ways:

[0109] Method 1:

[0110] The first indication information includes a first bit, which is used to indicate the position of the PO that the subgroup to which the terminal belongs needs to monitor among the at least one first POs associated with the first indication information.

[0111] Among them, the first indication information may include at least one PO, and each PO may correspond to at least one subgroup. The first bit of each subgroup corresponding to each PO is used to indicate the PO position that the corresponding subgroup needs to monitor among the at least one first POs associated with the first indication information. Optionally, the subgroup may also be referred to as a terminal subgroup, which is not limited in the present application.

[0112] Figure 4 A schematic diagram of the first indication information is shown. As Figure 4As shown, the first indication information may include a * b * n bits. Wherein, a represents the number of POs included in the first indication information, b represents the number of subgroups included in each PO included in the first indication information, and n is the number of bits of the binary representation of the number of at least one first PO associated with the first indication information. For example, when the number of at least one first PO associated with the first indication information is 8, n is 3 bits. The value of the number of bits of this binary representation can be used to indicate the PO specified in at least one first PO for the corresponding subgroup, that is, the PO that the terminals in the corresponding subgroup (such as all terminals in the subgroup) need to monitor. Here, the number of bits of this binary representation is the above-mentioned first bit.

[0113] In Figure 4 this example, the first indication information includes 4 POs, that is, a = 4; the number of subgroups included in each PO is 4, that is, b = 4; the number of at least one first PO associated with the first indication information is 8, that is, n = 3. Continuing to refer to Figure 4 , when the first bit corresponding to subgroup 2 (sub2) under PO1 in the first indication information is 001, it means that all terminals belonging to subgroup 2 under PO1 actually need to monitor the second PO in at least one first PO associated with the first indication information. When the first bit corresponding to subgroup 3 (sub3) under PO1 in the first indication information is 010, it means that all terminals belonging to subgroup 3 under PO1 actually need to monitor the third PO in at least one first PO associated with the first indication information.

[0114] Therefore, in this way, for the terminals of each subgroup under each PO in the first indication information, the network side can indicate the specific PO associated that the terminals of the corresponding group need to monitor through n bits, so that the network side can control the terminals to monitor messages under specific POs according to needs.

[0115] In some embodiments, the first indication information may further include bit #1, which is used to indicate whether the subgroup to which the terminal belongs needs to monitor the PO.

[0116] Exemplarily, each subgroup corresponding to each PO included in the first indication information may correspond to bit #1, which is used to indicate whether the corresponding subgroup needs to monitor the PO. By indicating whether each subgroup needs to monitor the PO, the probability of incorrect wake-up of the terminal can be reduced, and the power consumption of the terminal can be reduced. The position of bit #1 may be in the first indication information, or it may be the PEI indication in the existing mechanism, which is not limited here.

[0117] Figure 5 shows another schematic diagram of the first indication information. As Figure 5 shown, the first indication information may include a * b * (n + 1) bits. Wherein, a, b, n are the same as Figure 4has the same or similar meaning, and reference may be made to the relevant descriptions in the foregoing text. Among them, the bit of "+1" is bit #1, which is used to indicate whether the corresponding subgroup needs to monitor the PO.

[0118] In Figure 5 In this example, the first indication information includes 4 POs, that is, a = 4; the number of subgroups included in each PO is 4, that is, b = 4; the number of at least one first PO associated with the first indication information is 8, that is, n = 3. Continue to refer to Figure 5 , when the first bit corresponding to subgroup 2 (sub2) under PO1 in the first indication information is 0011, it means that all terminals belonging to subgroup 2 under PO1 actually need to monitor the second PO among at least one first PO associated with the first indication information, and all terminals belonging to subgroup 2 need to wake up and monitor. When the first bit corresponding to subgroup 3 (sub3) under PO1 in the first indication information is 0100, it means that all terminals belonging to subgroup 3 under PO1 actually need to monitor the third PO among at least one first PO associated with the first indication information, and all terminals belonging to subgroup 3 do not need to wake up and monitor.

[0119] Therefore, for the terminals of each subgroup under each PO in the first indication information, the network side can control whether the terminals of each subgroup need to monitor the message at the position that needs to be monitored through 1 bit.

[0120] Method 2

[0121] The first indication information includes a second bit, and the second bit is used to indicate the position of the PO that the terminals corresponding to the POs included in the first indication information need to monitor among at least one first PO.

[0122] Among them, the first indication information may include at least one PO, where each PO may correspond to multiple terminals, and each PO corresponds to a common bit, which can be used to indicate the position of the PO that the multiple terminals (such as all terminals corresponding to each PO) need to monitor among at least one first PO associated with the first indication information. At this time, the POs that the multiple terminals need to monitor are the same, both are the PO indicated by the common bit.

[0123] Optionally, the multiple terminals corresponding to each PO may be divided into multiple subgroups. At this time, the common bit is used to indicate the position that the multiple subgroups (such as all subgroups) need to monitor among at least one first PO associated with the first indication information. At this time, the POs that the multiple subgroups need to monitor are the same, both are the PO indicated by the common bit.

[0124] Figure 6 Shows another schematic diagram of the first indication information. As Figure 6As shown, the first indication information may include a*n bits. Here, a represents the number of POs included in the first indication information, and n is the number of bits of the binary representation of the number of at least one first PO associated with the first indication information. For example, when the number of at least one first PO associated with the first indication information is 8, n is 3 bits. The value of the number of bits of this binary representation can be used to indicate the PO specified by the terminals corresponding to the corresponding PO (such as all terminals corresponding to the PO) among at least one first PO, that is, the PO that the terminals corresponding to the corresponding PO (such as all terminals corresponding to the PO) need to monitor. Here, the number of bits of this binary representation is the above-mentioned second bit, that is, the above-mentioned common bit.

[0125] In Figure 6 this example, the first indication information includes 4 POs, that is, a = 4; the number of at least one first PO associated with the first indication information is 8, that is, n = 3. Continuing to refer to Figure 6 , when the common bit under PO1 in the first indication information is 001, it means that all terminals under PO1 actually need to monitor the second PO among at least one first PO associated with the first indication information. In this way, each PO included in the first indication information may include a common bit to indicate the PO position actually monitored by all terminals (or all subgroups of terminals) corresponding to the corresponding PO.

[0126] Therefore, in this way, for the terminals under each PO in the first indication information, the network side can indicate the specific PO associated that the corresponding terminals need to monitor through n bits, so that the network side can control the terminals to monitor messages under specific POs as needed.

[0127] In some embodiments, the first indication information may further include bit #2, which is used to indicate whether the subgroup to which the terminal belongs needs to monitor the PO. By indicating whether each subgroup needs to monitor the PO, the probability of incorrect wake-up of the terminal can be reduced, and the power consumption of the terminal can be reduced.

[0128] Exemplarily, each subgroup corresponding to each PO included in the first indication information may correspond to bit #2, which is used to indicate whether the corresponding subgroup needs to monitor the PO. The position of bit #2 may be located in the first indication information, or be indicated by PEI in the existing mechanism, which is not limited herein.

[0129] Figure 7 shows another schematic diagram of the first indication information. As Figure 7 shown, the first indication information may include a*(b + n) bits. Among them, a and n have the same or similar meanings as Figure 6 , and the relevant descriptions in the above text can be referred to. b represents the number of subgroups included in each PO included in the first indication information.

[0130] In Figure 7 this example, the first indication information includes 4 POs, i.e., a = 4; the number of subgroups included in each PO is 4, i.e., b = 4; the number of at least one first PO associated with the first indication information is 8, i.e., n = 3. Continuing to refer to Figure 7 , when all the common bits (i.e., the second bits) corresponding to the subgroups under PO1 in the first indication information are 001, it indicates that for the terminals corresponding to all the subgroups under PO1, they actually need to monitor the second PO among at least one first PO associated with the first indication information. Optionally, all the terminals belonging to subgroup 1 under PO1 need to wake up and monitor, all the terminals belonging to subgroup 2 do not need to wake up and monitor, and all the terminals belonging to subgroup 3 do not need to wake up and monitor.

[0131] In this way, by making the start bit of each PO included in the first indication information be a common actual monitoring position indication, that is, for the terminals of each subgroup, they first need to judge their actual monitoring position through this common bit. For example, if the first indication information is associated with a total of 8 POs and the common bit is three bits, it means that the terminals of all the subgroups corresponding to the PO at this monitoring position need to go to the specific PO indicated by the common bit to monitor the PDCCH scrambled with P-RNTI. After reading the common bit, the terminals of each subgroup then judge whether they need to wake up and monitor the message according to their subgroup numbers.

[0132] Method 3

[0133] The first indication information includes a third bit, which is used to indicate the position of the PO that the terminal corresponding to the first indication information needs to monitor among at least one first PO.

[0134] Among them, the first indication information may include at least one PO, where each PO may correspond to multiple terminals. The at least one PO commonly corresponds to a common bit, which can be used to indicate the position of the PO that the multiple terminals (such as all the terminals corresponding to all the POs) need to monitor among at least one first PO associated with the first indication information. At this time, the POs that the multiple terminals need to monitor are the same, which is the PO indicated by the common bit.

[0135] Optionally, the multiple terminals corresponding to each PO can be divided into multiple subgroups. At this time, the common bit is used to indicate the positions that the multiple subgroups (such as all the subgroups) corresponding to at least one PO included in the first indication information need to monitor among at least one first PO associated with the first indication information. At this time, the POs that the multiple subgroups need to monitor are the same, which is the PO indicated by the common bit.

[0136] Figure 8Another schematic diagram showing the first indication information is as follows Figure 8 As shown, the first indication information may include (a + n) bits. Here, a represents the number of POs included in the first indication information, and n is the number of bits of the binary representation of the number of at least one first PO associated with the first indication information. For example, when the number of at least one first PO associated with the first indication information is 8, n is 3 bits. The value of the number of bits of this binary representation can be used to indicate the PO specified by the terminals of all POs (such as all terminals corresponding to all POs) among at least one first PO, that is, the PO that the terminals of all POs (such as all terminals corresponding to all POs) need to monitor. Here, the number of bits of this binary representation is the above-mentioned second bit, that is, the above-mentioned common bit.

[0137] In Figure 8 this example, the first indication information includes 4 POs, that is, a = 4; the number of at least one first PO associated with the first indication information is 8, that is, n = 3. Continuing to refer to Figure 6 , when the common bit in the first indication information is 001, it means that for all terminals under PO1 - PO4, they actually need to monitor the second PO among at least one first PO associated with the first indication information.

[0138] Therefore, in this way, for the terminals under all POs in the first indication information, the network side can indicate the specific PO that all terminals need to monitor through n bits, so that the network side can control the terminals to monitor messages under specific POs according to needs.

[0139] In some embodiments, the first indication information may further include bit #3, which is used to indicate whether the subgroup to which the terminal belongs needs to monitor the PO. By indicating whether each subgroup needs to monitor the PO, the probability of incorrect wake-up of the terminal can be reduced, and the power consumption of the terminal can be reduced. The position of bit #3 can be in the first indication information, or it can be the PEI indication in the existing mechanism, which is not limited here.

[0140] Exemplarily, each subgroup corresponding to each PO included in the first indication information may correspond to bit #3, which is used to indicate whether the corresponding subgroup needs to monitor the PO.

[0141] Figure 9 Another schematic diagram showing the first indication information is as follows Figure 9 As shown, the first indication information may include n + a * b bits. Here, a and n have the same or similar meanings as in Figure 8 , and the relevant descriptions in the above text can be referred to. b represents the number of subgroups included in each PO included in the first indication information.

[0142] In Figure 9In this example, the first indication information includes 4 POs, i.e., a = 4; the number of subgroups included in each PO is 4, i.e., b = 4; the number of at least one first PO associated with the first indication information is 8, i.e., n = 3. Continue to refer to Figure 7 , when the common bit (i.e., the third bit) in the first indication information is 001, it indicates that all terminals under PO1 - PO4 actually need to monitor the second PO among at least one first PO associated with the first indication information. Optionally, all terminals belonging to subgroup 1 under PO1 need to wake up and monitor, all terminals belonging to subgroup 2 do not need to wake up and monitor, and all terminals belonging to subgroup 3 do not need to wake up and monitor.

[0143] In this way, by making the starting bit (or specific bit) position of the first indication information be a common actual monitoring position indication, that is, for all terminals under all POs included in the first indication information, they first need to judge their actual monitoring positions through this common bit. For example, if the first indication information is associated with a total of 8 POs and the common bit is three bits, it means that all terminals at this monitoring position need to go to the specific PO indicated by the common bit to monitor the PDCCH scrambled with P-RNTI. After reading the common bit, each terminal then judges whether it needs to wake up and monitor the message according to its subgroup number.

[0144] Optionally, the position of the third bit can be the starting bit in the first indication information, or a specific bit in the first indication information, and this application does not limit this. Among them, the position of the third bit can be network indication, or pre-defined by the protocol, and this application does not limit this.

[0145] In some embodiments, the number of POs included in the first indication information is an integer multiple of the number of POs in a PF.

[0146] Exemplarily, when the number of POs included in the first indication information is the number of POs in a PF (i.e., the number of actually monitored POs Ns), the first indication information is associated with a PF. For example, the network can configure that the first indication information includes 4 POs. At this time, if the number of POs included in an actually configured PF is 4, then the first indication information is associated with a PF.

[0147] Exemplarily, when the number of POs included in the first indication information is X times (X is a positive integer greater than 1) the number of POs in a PF, the first indication information is associated with two or more PFs. For example, the network can configure that the first indication information includes 8 POs. At this time, if the number of POs included in an actually configured PF is 4, then the first indication information is associated with 2 PFs.

[0148] In some embodiments, the first indication information further includes a fourth bit, which is used to indicate whether the subgroup to which the terminal belongs needs to monitor the PO. Exemplarily, the fourth bit may be the above-mentioned bit #1, bit #2, or bit #3, etc., without limitation.

[0149] 320. The terminal determines that it needs to monitor the PO according to the first information.

[0150] Exemplarily, for the PO that needs to be monitored, the terminal may monitor the message on this PO. For example, for a terminal in the idle state or inactive state, it can wake up on the PO that needs to be monitored to monitor the paging message or receive a short message. For another example, for a connected terminal, it can receive a short message on the PO that needs to be monitored to monitor the change of system information.

[0151] In some embodiments, when the first information is the first indication information, the terminal may determine the PO to be monitored from at least one first PO associated with the first indication information according to the indication.

[0152] As a realizable manner, for the first indication information in mode 1 in step 310, the terminal may determine the PO to be monitored from at least one first PO associated with the first indication information according to the first bit. Exemplarily, the terminal may determine the PO to be monitored according to the following step 11 and step 12.

[0153] Step 11: The terminal calculates the position of the PO to be monitored in the first indication information, that is, which PO in at least one PO included in the first indication information needs to be monitored. Exemplarily, it can be calculated according to the following formula:

[0154] i PO = ((UE_ID mod N)·N S + i_s) mod po

[0155] where, i PO is the index of the PO included in the first indication information that needs to be monitored. UE_ID, N, and i_s can refer to the relevant descriptions in the above text. N po is the number of POs included in the first indication information.

[0156] Step 12: The terminal determines the position of the PO to be monitored according to the monitored PO position calculated in step 11 and according to the first bit corresponding to the subgroup number of the subgroup to which this PO position belongs. Optionally, the terminal may also determine whether to monitor the PO according to the subgroup number of the subgroup to which this PO position belongs, such as monitoring the PDCCH scrambled by P-RNTI.

[0157] Exemplarily, the terminal may determine the corresponding PO among the POs included in the first indication information according to the PO position calculated in step 11, then obtain the first bit corresponding to the subgroup to which the terminal belongs in the PO, and determine the PO position that the subgroup to which the terminal belongs needs to monitor among at least one first PO associated with the first indication information according to the first bit. Optionally, the bit #1 corresponding to the subgroup to which the terminal belongs in the PO may also be obtained, and it is determined whether the subgroup to which the terminal belongs needs to monitor the message at the associated PO position according to the bit #1.

[0158] As an example, for Figure 4 the first indication information in, the terminal may, according to the PO index calculated in step 11, according to the 4 * 3 bits included in the corresponding PO position, and according to the 3 bit values (i.e., the first bit) of the subgroup to which the terminal belongs, determine the specific PO monitoring message to the 8 first POs associated with the first indication information.

[0159] As another example, for Figure 5 the first indication information in, in addition to determining the specific PO monitoring message to the 8 first POs associated with the first indication information according to the 3 bit values of the subgroup to which the terminal belongs, the terminal may also determine whether to monitor the message on the PO according to the 1 bit value of the subgroup to which the terminal belongs under the corresponding PO.

[0160] As another implementable manner, for the first indication information in manner 2 in step 310, the terminal may determine the PO to be monitored among at least one first PO associated with the first indication information according to the second bit. Exemplarily, the terminal may determine the PO to be monitored according to the following step 21 and step 22.

[0161] Step 21: The same as step 11 above.

[0162] Step 22: The terminal determines the PO position to be monitored according to the monitored PO position calculated in step 21 and according to the second bit corresponding to the PO position. Optionally, the terminal may also determine whether to monitor the PO according to the subgroup number of the subgroup to which the PO position belongs, such as monitoring the PDCCH scrambled by P-RNTI.

[0163] Exemplarily, the terminal may determine the corresponding PO among the POs included in the first indication information according to the PO position calculated in step 21, then obtain the second bit corresponding to the PO, and determine the PO position that all terminals (or subgroups) under the PO need to monitor among at least one first PO associated with the first indication information according to the second bit. Optionally, the bit #2 corresponding to the subgroup to which the terminal belongs in the PO may also be obtained, and it is determined whether the subgroup to which the terminal belongs needs to monitor the message at the associated PO position according to the bit #2.

[0164] As an example, forFigure 6 Regarding the first indication information in Figure 6 , the terminal can, according to the PO index calculated in step 21, determine the specific PO monitoring message among the 8 first POs associated with the first indication information based on the 3 bits (i.e., the second bit) included in the corresponding PO position.

[0165] As another example, for Figure 7 Regarding the first indication information in Figure 7 , in addition to determining the specific PO monitoring message among the 8 first POs associated with the first indication information based on the 3-bit value of the corresponding PO position, the terminal can also determine whether to monitor the message on the PO based on the 1-bit value of the subgroup to which the PO belongs.

[0166] As another implementable manner, for the first indication information in manner 3 of step 310, the terminal can determine the PO to be monitored among at least one first PO associated with the first indication information according to the third bit. Exemplarily, the terminal can determine the PO to be monitored according to the following steps 31 and 32.

[0167] (Optional) Step 31: Same as step 11 above.

[0168] Step 32: The terminal determines the PO position to be monitored according to the common third bit of all POs included in the first indication information. Optionally, the terminal can also determine whether to monitor the PO according to the monitored PO position calculated in step 31 and the subgroup number of the subgroup to which it belongs, such as monitoring the PDCCH scrambled by P-RNTI.

[0169] Exemplarily, the terminal can determine the PO position to be monitored by all terminals (or subgroups) under all POs in the first indication information among at least one first PO associated with the first indication information according to the third bits corresponding to all POs in the first indication information. Optionally, the terminal can also determine the corresponding PO among the POs included in the first indication information according to the PO position calculated in step 31, and then can also obtain the bit #3 corresponding to the subgroup to which the terminal in the PO belongs, and determine whether the subgroup to which the terminal belongs needs to monitor the message at the associated PO position according to the bit #3.

[0170] As an example, for Figure 8 Regarding the first indication information in Figure 8 , the terminal can determine the specific PO monitoring message among the 8 first POs associated with the first indication information according to the 3 bits (i.e., the third bit) at the starting position of the first indication information (a specific position).

[0171] As another example, for Figure 9For the first indication information in it, in addition to determining, according to the corresponding 3-bit values, that it is necessary to monitor a specific PO message among the 8 first POs associated with the first indication information, the terminal can also determine whether it is necessary to monitor a message on the PO according to 1-bit value of the subgroup to which the PO belongs.

[0172] In some embodiments, the terminal can determine a first PF in at least one paging frame PF according to the position of the PO that needs to be monitored indicated by the first indication information; and determine the PO that needs to be monitored in the first PF.

[0173] As an example, when the terminal is associated with a PF (this PF is the first PF), the position of the PO that needs to be monitored indicated in the first indication information can be directly mapped to the PO index that needs to be monitored in the associated PF. For example, 4 POs are configured in a PF, and the number of bits corresponding to the PO associated with the first indication information can be configured to 2 bits. When these 2 bits indicate 00, it is mapped that the corresponding subgroup (or terminal) needs to go to the first PO position of the associated PF to monitor; when these 2 bits indicate 01, it is mapped that the corresponding subgroup (or terminal) needs to go to the second PO position of the associated PF to monitor, and so on.

[0174] As another example, when the terminal is associated with two or more PFs, the terminal can deduce the first PF (such as which PF) in the associated PFs that needs to be mapped according to the position of the PO that needs to be monitored indicated in the first indication information, and further determine the mapped PO in this first PF. For example, 4 POs are configured in a PF, and the number of bits corresponding to the PO associated with the first indication information can be configured to 3 bits. When these 3 bits indicate 101, it is mapped that the corresponding subgroup (or terminal) needs to go to the second PO position of the second PF associated to monitor.

[0175] Optionally, the first indication information can achieve the purpose of aggregating the POs (i.e., specific POs) that the terminal needs to monitor through the above-mentioned methods 1 to 3. Among them, the difference between the three methods lies in different control granularities. For example, in method 1, it can be controlled which PO position the terminals of each subgroup under each PO in the first indication information go to monitor respectively; in method 2, it can be controlled which PO position the terminals (such as all terminals) under each PO in the first indication information go to monitor respectively; in method 3, it can be controlled which PO position the terminals (such as all terminals) under all POs in the first indication information go to monitor. Among them, method 1 has a finer control granularity and higher flexibility.

[0176] In some embodiments, the first indication information can also be implemented in the form of a combination of PEI and a first bit (or a second bit or a third bit). That is to say, the first indication information can be obtained by additionally adding a first bit (or a second bit or a third bit) on the basis of the existing PEI.

[0177] It should be noted that the embodiments of the present application do not limit the position or order of each type of bit in the first indication information within the first indication information.

[0178] In some embodiments, the terminal may further receive second indication information from the network-side device, where the second indication information is used to indicate whether the terminal needs to monitor a second PO associated with the second indication information.

[0179] Specifically, the network-side device may send second indication information to the terminal to indicate whether the terminal needs to monitor at least one second PO associated with the second indication information. Correspondingly, the terminal receives the second indication information. Among them, at least one second PO associated with the second indication information refers to at least one PO that may need to be monitored by the terminal and is associated with the second indication information. Specifically, the second indication information may be associated with one PF, and further may also be expressed as being associated with at least one PO in this one PF. Or, the second indication information may be associated with two or more PFs, and further may be expressed as being associated with at least one PO in these PFs. Or, the second indication information may be associated with all PFs or all POs. That is to say, the second PO may be a set of all PF or PO positions calculated by all terminals according to the paging configuration. Associating one or more PFs or POs may be based on network configuration or protocol convention, which is not limited here. Therefore, through the embodiments of the present application, by sending the second indication information to the terminal, it is possible to indicate whether the terminal needs to monitor the PO.

[0180] Exemplarily, the second indication information may be the PEI in the R17 standard, or may be an enhanced indication related to the PEI, such as the extensible PEI. Specifically, in the existing R17 standard, the PEI can be associated with at most two PFs, while the enhanced PEI can be associated with multiple (more than 2) PFs.

[0181] As a specific example, the second indication information may include 4 POs, and each PO may correspond to 4 subgroups. The network side may configure such that terminals in all subgroups at the positions of the first PO, the second PO, and the third PO in the second indication information do not perform message monitoring at their associated PO positions. For example, the bit corresponding to each subgroup under each PO is set to 0, indicating that the terminal does not wake up to monitor paging at its associated PO. If the bit corresponding to each subgroup under each PO is set to 1, it indicates that the terminal needs to wake up to monitor paging at its associated PO.

[0182] As a realizable manner, the above step 310 may be specifically implemented as:

[0183] The terminal receives second indication information from a network-side device; and the terminal receives third indication information from the network-side device, where the third indication information is used to indicate the POs that the terminal needs to monitor in the POs included in the second indication information.

[0184] Specifically, the network-side device may send third indication information to the terminal, which is used to indicate the POs that the terminal needs to monitor in the POs included in the second indication information. That is to say, the third indication information may indicate the specific PO positions in the second indication information (such as PEI). Correspondingly, the terminal receives the third indication information. At this time, the above first information includes the second indication information and the third indication information.

[0185] It should be noted that the second indication information and the third indication information may be sent to the terminal in the same message or in different messages, and the present application does not make any limitations in this regard.

[0186] Optionally, the first information may also include the third indication information, and the present application does not make any limitations in this regard.

[0187] Correspondingly, step 320 above may be implemented as: based on the third indication information, the terminal can find the associated PO positions that need to be monitored at the specific PO positions indicated by it. For example, if the second indication information includes 4 POs, and the terminal calculates that the PO in the second indication information that needs to be monitored is the first PO, and the third indication information indicates that the terminal needs to monitor the PO associated with the fourth PO in the second indication information, then the behavior of the terminal at this time is that it needs to monitor the first PO in the second indication information. If the first PO indicates that the subgroup to which the terminal belongs does not need to wake up at the associated PO position, then the terminal does not need to wake up at the associated PO position to monitor paging. In addition, the terminal also needs to wake up at the PO position associated with the fourth PO in the second indication information to monitor paging. Therefore, through the embodiment of the present application, by sending the third indication information to the terminal, it is possible to indicate the PO positions associated with the specific POs that the terminal needs to monitor in the POs included in the second indication information, so as to change the PO positions monitored by the terminal and achieve the purpose of aggregated paging.

[0188] Another implementation manner may also be that the terminal may further monitor at the specific PO positions indicated by the third indication information whether it needs to monitor at the associated PO positions, such as waking up to monitor the PDCCH scrambled by P-RNTI.

[0189] For example, if the second indication information contains 4 POs, and the PO that the terminal needs to monitor in the second indication information is the first PO, and the third indication information indicates that the terminal also needs to monitor the fourth PO in the second indication information, then the behavior of the terminal at this time is that it needs to monitor the first PO in the second indication information. If the first PO indicates that the subgroup to which the terminal belongs does not need to wake up at the associated PO position, then the terminal does not need to wake up at the associated PO position to monitor paging. In addition, the terminal also needs to monitor the fourth PO in the second indication information. If the fourth PO indicates that the subgroup to which the terminal belongs needs to wake up at the associated PO position, then the terminal needs to wake up at the PO position associated with the fourth PO to monitor paging. Therefore, by sending the third indication information to the terminal, the embodiment of the present application can indicate the specific PO position that the terminal needs to monitor among the POs included in the second indication information, so as to change the monitored PO position of the terminal by controlling whether the terminal needs to wake up at the associated PO position at this specific PO position, and achieve the purpose of aggregated paging.

[0190] It should be noted that the embodiment of the present application does not limit the manner in which the network-side device controls the terminal not to monitor at the associated PO. In one example, the network-side device can control the terminal not to monitor at the associated PO position through the second indication information. In another example, the network-side device activates the terminal to monitor at its own PO position through other signaling. Here, its own PO position refers to the PO position calculated by the terminal.

[0191] As another implementable manner, the protocol can also pre-define the POs that need to be monitored (i.e., specific POs) among the POs included in the second indication information. At this time, the network-side device does not need to send the third indication information to the terminal anymore. At this time, the second indication information can be an example of the above first information.

[0192] Correspondingly, step 320 can be specifically implemented as: the terminal monitors paging at the PO associated with the specific PO among at least one PO included in the second indication information pre-defined by the protocol. Optionally, the terminal can further monitor at the pre-defined specific PO position of the protocol whether it needs to monitor at its associated PO position, such as waking up to monitor the PDCCH scrambled by P-RNTI.

[0193] In some embodiments, the terminal can also receive the fourth indication information from the network-side device, and the fourth indication information is used to enable the terminal to monitor on the POs that need to be monitored among the POs included in the second indication information.

[0194] Exemplarily, in the case of the PO that needs to be listened for in the PO included in the second indication information predefined by the protocol, before listening for the PO, the terminal may receive the fourth indication information sent by the network device, and enable the terminal to listen on the PO that needs to be listened for in the PO included in the second indication information according to the fourth indication information. At this time, the fourth indication information may be an example of the first information.

[0195] Optionally, when the terminal does not receive the fourth indication information, it may default to not being enabled, that is, not listening for the associated PO on the specific PO included in the second indication information predefined by the protocol.

[0196] Exemplarily, for the specific PO position included in the second indication information (such as the PO position indicated by the third indication information or predefined by the protocol), the terminal needs to continue to determine whether it needs to wake up and listen at the associated PO position that needs to be listened for at this PO position. For example, the protocol may stipulate that all terminals need to listen at the last PO position in the second indication information. Continuing with the above example, among the first to third PO positions in the 4 POs in the second indication information, the terminals in all subgroups do not listen at their actual associated PO positions, and at the same time the protocol stipulates that all terminals also need to listen at the fourth PO position in the 4 POs in the second indication information. In this way, all terminals can be gathered to listen at the fourth PO position. Further, the terminal may determine whether it needs to listen at its associated actual PO position according to the information of the fourth PO.

[0197] In some embodiments, step 310 above may be specifically implemented as:

[0198] The terminal receives the fifth indication information from the network device, and the fifth indication information is used to indicate switching to the first paging configuration; the first paging configuration is used to configure the PF and PO that the terminal needs to listen for.

[0199] Specifically, the network device may pre - send paging - related configurations to the terminal, such as the first paging configuration. Among them, the first paging configuration is used to configure the PF and PO that the terminal needs to listen for. Exemplarily, the first paging configuration may configure one PF that the terminal needs to listen for and one PO under this PF. In this way, the terminal can uniquely determine the PO that needs to be listened for according to this first paging configuration. The network may configure one set or multiple sets of first paging configurations. When configuring multiple sets of paging configurations, in one implementation manner, the network configures a paging configuration list, and this list may contain multiple sets of first paging configurations. At this time, the fifth indication information may be an example of the above - mentioned first information.

[0200] Correspondingly, the above step 320 can be implemented as follows: The terminal switches from the existing paging configuration to the first paging configuration according to the fifth indication information, or when multiple sets of first paging configurations are configured, it can switch from paging configuration 1 to paging configuration 2, so as to determine the PF and PO that need to be monitored. The specific paging configuration to be switched is not limited herein.

[0201] Exemplarily, when the network side device does not use the relevant energy-saving scheme and the corresponding terminal uses the paging configuration corresponding to each PF and PO evenly distributed within the DRX cycle, if the network side device sends the fifth indication information to the terminal to instruct the terminal to switch to the first paging configuration. Correspondingly, the terminal can switch to the first paging configuration according to the fifth indication information, so as to determine the PF and PO that need to be monitored. Therefore, through this first paging configuration, the terminals that support listening for messages on a specific PO can be configured at the same PO position, so as to achieve the purpose of aggregating the POs (i.e., specific POs) that the terminals need to monitor.

[0202] In some embodiments, step 320 can be implemented as at least one of the following:

[0203] The terminal listens for paging messages on the PO that needs to be monitored;

[0204] The terminal listens for short messages on the PO that is needed.

[0205] Exemplarily, for a terminal in the idle state or the inactive state, it can listen for paging messages or short messages on the PO that needs to be monitored. For a connected terminal, it can listen for short messages on the PO that needs to be monitored. Specifically, for a connected terminal, there is no need to listen for paging messages, but it needs to listen for short messages at the PO position, and then determine whether the system information has changed according to the short message. Therefore, for a connected terminal, through the embodiments of the present application, it is possible to aggregate the short messages that the terminal needs to monitor, thereby achieving energy saving for the network side device.

[0206] Therefore, the embodiments of the present application instruct the terminal to the paging occasion PO that needs to be monitored, so that the terminal can perform message listening on the specified PO that needs to be monitored, rather than listening for messages on the evenly distributed POs. Therefore, by controlling the terminal to listen for messages under the specified PO, it is beneficial for the network side device to page a specific terminal under the specified PO, for example, to achieve aggregating the POs that the terminal needs to monitor, which is beneficial to reducing the signaling overhead and the paging duration of the network side, and is beneficial to power saving of the network side.

[0207] In some embodiments, before the above step 310, the terminal may further receive configuration information from a network-side device, and the configuration information includes at least one of the following:

[0208] Configuration related to the first information;

[0209] One or more sets of first paging configurations related to PF;

[0210] One or more sets of first paging configurations related to PO;

[0211] Terminal grouping configuration.

[0212] Exemplarily, the terminal may obtain the above configuration information through system messages or dedicated signaling. Among them, the relevant configuration of PF or PO may include, but is not limited to, paging cycle T, the number N of PFs within the paging cycle, the number Ns of POs in each PF, the offset PF_offset for determining the used PF, etc., which are not limited. The terminal grouping configuration may include, but is not limited to, the maximum number of subgroups supported, the method of grouping based on UE ID and the number of subgroups, the method of grouping based on CN allocation and the number of subgroups, or other grouping methods, etc., which are not limited.

[0213] Optionally, the above first paging configuration related to PF or PO may include the relevant paging configuration for terminals supporting aggregated paging. For example, the existing mechanism's paging configuration supports configuring at least two PFs at least, and for the first paging configuration, one PF can be supported. For example, for the current N, the network can be configured as oneT, halfT, quarterT, oneEighthT, and oneSixteenthT. Optionally, for the first paging configuration, N may be extended to support onethirtysecondT, or the value of T may be extended, etc. Correspondingly, the terminal determines the positions of PFs and POs to be monitored according to the configuration information. Exemplarily, the configuration information may configure one PF and PO as the PO actually monitored by the terminal.

[0214] In some embodiments, the configuration related to the first information may include at least one of the following:

[0215] The number of POs included;

[0216] The payload size of the first information;

[0217] The offset of the first information;

[0218] The number of subgroups corresponding to each PO included in the POs;

[0219] The time domain or frequency domain position of the first information.

[0220] Exemplarily, when the first information includes the first indication information, the configuration related to the above-mentioned first information may include at least one of the number of POs included in the first indication information, the payload size of the first indication information, the offset of the first indication information, the number of subgroups corresponding to each PO in the POs included in the first indication information, the time domain or frequency domain position of the first indication information, etc.

[0221] When the first information includes the second indication information, the configuration related to the above-mentioned first information may include at least one of the number of POs included in the second indication information, the payload size of the second indication information, the offset of the second indication information, the number of subgroups corresponding to each PO in the POs included in the second indication information, the time domain or frequency domain position of the second indication information, etc.

[0222] When the first information includes the above-mentioned third indication information, fourth indication information or fifth indication information, the configuration related to the above-mentioned first information may include at least one of the time domain and frequency domain positions of the corresponding indication information.

[0223] In some embodiments, the terminal may further determine the number of PFs associated with the terminal according to the above configuration information; and determine the time-frequency position of the first PF associated with the terminal according to the number of PFs associated with the terminal. Then, the terminal may determine the time-frequency position for receiving the first information according to the time-frequency position of the first PF and the offset of the first information. Further, the terminal may receive the first information according to the time-frequency position for receiving the first information.

[0224] Exemplarily, taking the first information including the first indication information as an example, when the configuration information indicates that the number of POs included in the first indication information is not greater than the number of actually monitored POs (Ns value), it may be determined that the first indication information is associated with one PF. At this time, this PF is the first PF associated. When the configuration information indicates that the number of POs included in the first indication information is greater than the number of actually monitored POs (Ns value), it may be determined that the first indication information is associated with two or more PFs. At this time, the first PF associated can be determined from the two or more PFs. Further, the terminal may determine the time-frequency position of the first indication information according to the position of the first PF and the offset of the first indication information configured by the network side. Further, the terminal may receive the first indication information at this time-frequency position.

[0225] For example, assume that the number of actually monitored POs Ns is 4, that is, one PF contains 4 POs. When the terminal calculates that the actually monitored PO index is 2 and determines that the PO index to be monitored in the first indication information is 6 according to the configuration information, it can be determined that the PF associated with the terminal belongs to the second PF. Further, the terminal can determine the position of the first PF.

[0226] In some embodiments, the protocol may pre-define the Paging Opportunities (POs) that the terminal needs to monitor, such as pre-defining the PO index that the terminal actually needs to monitor, or the Physical Frame (PF) location that needs to be monitored (such as the System Frame Number (SFN) of the PF), or the specific PO index in the PF location that needs to be monitored. Correspondingly, the terminal can determine the POs that need to be monitored according to the protocol agreement.

[0227] Optionally, the terminal may also receive fourth indication information from the network-side device, and the fourth indication information is used to enable the terminal to monitor at the PO positions that the protocol pre-defines for the terminal to monitor. Specifically, the fourth indication information can refer to the description in the above text and will not be elaborated here.

[0228] In some embodiments, the terminal can obtain configuration information to determine the PO positions that need to be monitored. Among them, the configuration information is used to configure the PO positions that the terminal needs to monitor. Specifically, the network-side device can send this configuration information.

[0229] Exemplarily, the configuration information may include relevant paging configurations for terminals that support aggregated paging. For example, through the paging configuration of the existing mechanism, it is calculated that at least two PFs can be supported. For the relevant paging configurations of terminals that support aggregated paging, through the calculation formulas of PF and PO, such as the calculation formulas of the existing mechanism can be reused, and it is calculated that one PF can be supported. For example, for the current N, the network can be configured as oneT, halfT, quarterT, oneEighthT, and oneSixteenthT. For the first paging configuration, N may be extended to support onethirtysecondT, or the value of T can be extended, etc. Correspondingly, the terminal determines the PF and PO positions that need to be monitored according to this configuration information. Exemplarily, the configuration information can configure one PF and PO as the PO that the terminal actually monitors, so as to achieve the purpose of aggregated paging.
