Description

Technical Field

[0001] The present application relates to the field of communication technology, and in particular to a signal transmission method, device, and readable storage medium. Background Art

[0002] In NR (New Radio) systems, power-saving designs for UEs (User Equipment) are essential. To address this, we propose a power-saving solution for the RRC_IDLE (Radio Resource Control-Idle) state, specifically reducing unnecessary paging.

[0003] Among them, the paging message in the NR protocol consists of two parts, namely paging PDCCH (Physical downlink control channel) and paging PDSCH (Physical downlink shared channel). Based on power saving considerations, the paging reception of UEs in RRC_IDLE and RRC_INACTIVE (RRC inactive state) states needs to follow the DRX (Discontinuous Reception) principle. Usually, the network side will configure the paging cycle, namely the DRX cycle, for the UE through high-layer signaling. The UE monitors a paging occasion (PO) in each DRX cycle. A PO consists of a group of PDCCH monitoring occasions (MO), which can contain multiple time slots (such as subframes or OFDM (Orthogonal frequency division multiplex) symbols). Paging DCI (Downlink control Information) is sent on the PDCCH MO. A paging frame (Paging Frame) is a radio frame that can contain one or more POs or the starting point of a PO. In multi-beam operation, the UE assumes that all transmission beams are repeatedly transmitting the same paging and short messages. Selecting the appropriate beam and receiving the paging and short messages is a UE implementation issue.

[0004] The Paging PDCCH under RRC-Idle / Inactive (inactive state) defined in the prior art is encrypted by P-RNTI (Paging RNTI, paging RNTI), and P-RNTI is shared by all UEs. At the corresponding PO moment, multiple UEs may need to monitor paging. As long as one UE has a paging message, the network side will send P-RNTI-encrypted DCI at the PO moment for the transmission of paging of the UE. Other UEs at the PO moment, regardless of whether they have their own Paging, need to wake up to monitor the P-RNTI-encrypted DCI. Once the P-RNTI-encrypted DCI is detected, subsequent related operations are performed, including PDCCH and PDSCH demodulation and decoding, until the UE finds that it is not in the UE list information that records the sending of the Paging message. This method causes unnecessary power consumption of the UE.

[0005] To reduce the probability of false paging alarms, the existing technology proposes that the network side sends a PEI (Paging Early Indication) in advance before the PO. If the PEI indicates that the terminal has a paging message in the subsequent PO, the terminal will monitor the paging PDCCH on multiple MOs in the subsequent PO to receive the paging message. Otherwise, the terminal will turn off the receiver and enter sleep mode, and will not attempt to receive paging messages in the corresponding PO.

[0006] There are two candidate PEI solutions: DCI-based PEI and sequence-based PEI. Sequence-based PEI offers superior detection performance compared to DCI-based PEI. However, when sequence-based PEI supports multiple POs, each of which supports multiple user groups, the two existing candidate solutions do not provide a good solution. This results in high network equipment overhead and complex terminal detection. Summary of the Invention

[0146] In the embodiments of this application, the term "and / or" describes the association relationship between associated objects, indicating that three relationships can exist. For example, A and / or B can represent three situations: A exists alone, A and B exist simultaneously, and B exists alone. The character " / " generally indicates that the associated objects are in an "or" relationship.

[0147] In the embodiments of the present application, the term "plurality" refers to two or more than two, and other quantifiers are similar.

[0148] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0149] The embodiments of the present application provide a signal transmission method, apparatus, and readable storage medium for reducing network device overhead and terminal detection complexity. The method and apparatus are based on the same patent application concept. Since the method and apparatus solve similar problems, the implementation of the apparatus and method can refer to each other, and any repetitions will not be repeated.

[0150] See also Figure 1 , Figure 1 is a flow chart of the signal transmission method provided in an embodiment of the present application, such as Figure 1 As shown, the following steps are included:

[0151] Step 101: A network device sends a power-saving signal to a terminal on a transmission resource. The power-saving signal is used to indicate whether there is paging information in a group of paging opportunities.

[0152] Among them, the energy-saving signals corresponding to the transmission resources are divided into at least one group of energy-saving signals, and each paging opportunity corresponds to at least one group of energy-saving signals; a group of energy-saving signals corresponding to each paging opportunity includes at least one energy-saving signal subgroup, and a user group within each paging opportunity corresponds to at least one energy-saving signal subgroup.

[0153] A group of energy-saving signals includes at least one energy-saving signal; a subgroup of energy-saving signals includes at least one energy-saving signal. The energy-saving signal may be, for example, a PEI. The terminal may be in RRC_IDLE or RRC_INACTIVE (radio resource control inactive state).

[0154] The set of paging opportunities may include one or more paging opportunities or multiple paging opportunity groups.

[0155] In an embodiment of the present application, the transmission resource may be one or more. Each paging opportunity corresponds to at least one group of energy-saving signals, including at least one of the following situations: each paging opportunity corresponds to a group of energy-saving signals; each paging opportunity corresponds to a group of energy-saving signals and a group of common energy-saving signals.

[0156] Specifically, when G2=N1, each paging opportunity corresponds to a group of energy-saving signals; when G2>N1, each paging opportunity corresponds to a group of energy-saving signals and a group of common energy-saving signals; wherein, G2 represents the number of energy-saving signal groups included in the energy-saving signal corresponding to the transmission resource (that is, the energy-saving signal corresponding to the transmission resource is divided into how many energy-saving signal groups), N1 represents the number of paging opportunities included in the paging opportunity group corresponding to a transmission resource, and G2 and N1 are both integers greater than 0.

[0157] In particular, if there is only one paging opportunity in the paging opportunity group, that is, G2=N1=1, then the one paging opportunity corresponds to a group of energy-saving signals. In other words, in this case, there is no energy-saving signal group associated with all paging opportunities.

[0158] To further reduce the terminal's detection complexity, the network device may also send one or both of the following information to the terminal: the number of user groups G1 included in each paging opportunity, and the number N1 of paging opportunities included in the paging opportunity group corresponding to a transmission resource. For example, the network device may notify the terminal using higher-layer signaling (such as SI (System Information)) or configure G1 and / or N1 using a method predefined in the protocol.

[0159] The grouping method of the energy-saving signals may be preset by a protocol or notified to the terminal by a network device via higher-layer signaling. For example, the network device may send first indication information to the terminal, where the first indication information is used to indicate how the energy-saving signals corresponding to the transmission resources are grouped into at least one group of energy-saving signals.

[0160] Wherein, one user group in each paging opportunity corresponds to at least one energy-saving signal subgroup, including at least one of the following situations:

[0161] One user group in each paging opportunity corresponds to one energy-saving signal subgroup; one user group in each paging opportunity corresponds to one energy-saving signal subgroup and one common energy-saving signal in each paging opportunity.

[0162] Specifically, when G3=G1, one user group in each paging opportunity corresponds to one energy-saving signal subgroup; when G3>G1, one user group in each paging opportunity corresponds to one energy-saving signal subgroup and one common energy-saving signal in each paging opportunity; wherein, G3 represents the number of energy-saving signal subgroups included in a group of energy-saving signals corresponding to each paging opportunity, and G1 represents the number of user groups included in each paging opportunity, and G3 and G1 are both integers greater than 0.

[0163] The manner in which the group of energy-saving signals corresponding to each paging opportunity is divided into energy-saving signal subgroups can be indicated to the terminal by the network device, thereby further reducing the complexity of terminal detection. Specifically, the network device sends second indication information to the terminal, where the second indication information is used to indicate the manner in which the group of energy-saving signals corresponding to each paging opportunity is divided into energy-saving signal subgroups.

[0164] When a network device sends an energy-saving signal to a terminal, the network device may send the energy-saving signal to the terminal on M1 transmission resources, where each transmission resource may send a maximum of M2 energy-saving signals. M1 and M2 are both integers. In this embodiment of the present application, M1 ≤ 2, and M2 ≤ 3.

[0165] Then, the network device may send one energy-saving signal, two energy-saving signals, or three energy-saving signals to the terminal on one transmission resource, or send an energy-saving signal to the terminal on two transmission resources, wherein one energy-saving signal, two energy-saving signals, or three energy-saving signals are sent on each transmission resource.

[0166] To further reduce the overhead of the network device, the network device may also send the energy-saving signal in at least one of the following ways:

[0167] When P≤P1, the network device sends one energy-saving signal to the terminal on one transmission resource; when P1<P≤P2, the network device sends two energy-saving signals to the terminal on one transmission resource; when P1<P≤P2, the network device sends one energy-saving signal to the terminal on two transmission resources respectively; when P>P3, the network device sends three energy-saving signals to the terminal on one transmission resource, or the network device sends three energy-saving signals to the terminal on two transmission resources respectively; wherein P represents the paging probability, P1, P2, and P3 represent a first preset value, a second preset value, and a third preset value, respectively, and P1<P2<P3; P, P1, P2, and P3 are all greater than 0. P1, P2, and P3 can be set according to actual needs.

[0168] In the embodiment of the present application, the energy-saving signal may be a public energy-saving signal dedicated to a paging opportunity group, an energy-saving signal corresponding to a paging opportunity, a public energy-saving signal dedicated to a paging opportunity, a public energy-saving signal dedicated to a paging opportunity, etc. Then, the network device sends the energy-saving signal to the terminal on the transmission resource, including at least one of the following:

[0169] When the network device needs to wake up M3 paging opportunities in the current paging opportunity group, the network device sends a public energy-saving signal exclusive to the paging opportunity group to the terminal, or the network device sends an energy-saving signal corresponding to each paging opportunity in the M3 paging opportunities to the terminal;

[0170] When the network device needs to wake up users in at least M4 paging opportunity groups, the network device sends a public energy-saving signal exclusive to the paging opportunity group to the terminal;

[0171] When the network device needs to wake up at least M5 user groups within a paging opportunity, the network device sends a paging opportunity-specific public energy-saving signal or a paging opportunity group-specific public energy-saving signal to the terminal;

[0172] When the network device needs to wake up one user group in a paging opportunity, the network device sends a user group-specific energy-saving signal to the terminal;

[0173] Wherein, M3 is an integer greater than 0 and less than or equal to the total number of paging opportunities within the paging opportunity group; M4 is an integer greater than 0; and M5 is an integer greater than 0 and less than or equal to the total number of user groups within the paging opportunity group. The values of M3, M4, and M5 can be set according to actual needs.

[0174] In an embodiment of the present application, when an energy-saving signal corresponds to multiple transmission opportunities and each transmission opportunity corresponds to multiple user groups, the energy-saving signal is divided into at least one group of energy-saving signals, each paging opportunity corresponds to at least one group of energy-saving signals, each group of energy-saving signals corresponding to each paging opportunity includes at least one energy-saving signal subgroup, and each user group within each paging opportunity corresponds to at least one energy-saving signal subgroup. Therefore, in this way, using the solution of the embodiment of the present application, there is no need to use sequence-based PEI to indicate all possible candidates, thereby reducing the overhead of network equipment; at the same time, for the terminal, there is no need to detect all possible candidates, thereby reducing the detection complexity of the terminal.

[0175] See also Figure 2 , Figure 2 is a flow chart of the signal transmission method provided in an embodiment of the present application, such as Figure 2 As shown, the following steps are included:

[0176] Step 201: A terminal receives a power-saving signal sent by a network device on a transmission resource, where the power-saving signal is used to indicate whether paging information exists in a group of paging opportunities.

[0177] The energy-saving signals corresponding to the transmission resources are divided into at least one group of energy-saving signals, and each paging opportunity corresponds to at least one group of energy-saving signals;

[0178] A group of energy-saving signals corresponding to each paging opportunity includes at least one energy-saving signal subgroup, and a user group within each paging opportunity corresponds to at least one energy-saving signal subgroup.

[0179] Depending on the different energy-saving signals sent by the network device in different situations, the terminal may also receive different energy-saving signals. Therefore, in practical applications, the terminal may receive at least one of the following signals:

[0180] Public energy-saving signal exclusive to the paging opportunity group; energy-saving signal corresponding to each paging opportunity; public energy-saving signal exclusive to the paging opportunity; energy-saving signal exclusive to the user group.

[0181] Step 202: The terminal receives a paging message according to the energy-saving signal.

[0182] If a public energy-saving signal exclusive to the paging opportunity group corresponding to the terminal or an energy-saving signal corresponding to each paging opportunity is detected on the transmission resource of the energy-saving signal, the terminal receives a paging message on the corresponding paging opportunity; if a public energy-saving signal exclusive to the paging opportunity corresponding to the terminal is detected on the transmission resource of the energy-saving signal, the terminal receives a paging message on the corresponding paging opportunity; if an energy-saving signal exclusive to the user group corresponding to the terminal is detected on the transmission resource of the energy-saving signal, the terminal receives a paging message on the corresponding paging opportunity.

[0183] In an embodiment of the present application, when an energy-saving signal corresponds to multiple transmission opportunities and each transmission opportunity corresponds to multiple user groups, the energy-saving signal is divided into at least one group of energy-saving signals, each paging opportunity corresponds to at least one group of energy-saving signals, each group of energy-saving signals corresponding to each paging opportunity includes at least one energy-saving signal subgroup, and each user group within each paging opportunity corresponds to at least one energy-saving signal subgroup. Therefore, in this way, using the solution of the embodiment of the present application, there is no need to use sequence-based PEI to indicate all possible candidates, thereby reducing the overhead of network equipment; at the same time, for the terminal, there is no need to detect all possible candidates, thereby reducing the detection complexity of the terminal.

[0184] Furthermore, based on the above embodiment, to further reduce the complexity of terminal detection, the terminal receives one or both of the following information sent by the network device, or obtains one or both of the following preset information: the number of user groups G1 included in each paging opportunity, and the number N1 of paging opportunities included in a paging opportunity group corresponding to a transmission resource. The terminal then determines, based on the information, how the energy-saving signal corresponding to the transmission resource is divided into at least one group of energy-saving signals.

[0185] In the embodiments of the present application, there is no limitation on how the terminal calculates the manner in which the energy-saving signals corresponding to the transmission resources are divided into at least one group of energy-saving signals. For example, the terminal may calculate based on certain parameters to obtain the manner in which the energy-saving signals corresponding to the transmission resources are divided into at least one group of energy-saving signals; or the manner in which the energy-saving signals corresponding to the transmission resources are divided into at least one group of energy-saving signals according to a preset rule.

[0186] Based on the above embodiments, one or more of the following steps may also be included: the terminal receives first indication information sent by the network device, and the first indication information is used to indicate how the energy-saving signal corresponding to the transmission resource is divided into at least one group of energy-saving signals; the terminal receives second indication information sent by the network device, and the second indication information is used to indicate how a group of energy-saving signals corresponding to each paging opportunity is divided into energy-saving signal subgroups.

[0187] The following describes the implementation process of the present application in combination with different embodiments. In the following embodiments, the network side device is described by taking a base station as an example.

[0188] As mentioned above, there are two candidate solutions for PEI, one is DCI-based PEI indication (DCI based PEI); the other is sequence-based PEI indication (sequence based PCI). Since NR in idle mode has neither CRS (Common Reference Signal) similar to LTE nor TRS (Tracking Reference Signal) signals periodically sent by NR in the connected state, when using DCI-based PEI indication, the terminal can only use multiple SSBs (Synchronization Signal and PBCH blocks) to perform channel time / frequency synchronization tracking, which will inevitably increase power consumption. Sequence-based PEI itself has channel synchronization function (for example, TRS can be used as PEI), which can further reduce terminal receiving power consumption.

[0189] In actual transmission, the average probability of a PO containing paging information is 10%, but sometimes there will be sudden paging information resulting in a higher paging probability. Therefore, under high paging rates, when the base station has configured PEI for the terminal, the base station can only send PEI to the terminal intensively, resulting in a sudden surge in system overhead, which may affect the transmission of PDSCH. On the other hand, the total number of paging frames (Paging Frame) N in each DRX cycle ranges from {T, T / 2, T / 4, T / 8, T / 16}, and the number of POs Ns contained in each paging frame ranges from {1, 2, 4}. N×Ns is used to characterize the median number of POs in a DRX cycle. When the value of N×Ns is relatively large, such as N=T, Ns=4, N*Ns=4T, it means that each wireless frame in the DRX cycle is a PF, and each PF contains 4 POs. At this time, the POs in the DRX cycle are dense, such as Figure 3 If dense POs are coupled with a high paging probability, the PEI system overhead will be further increased.

[0190] Assume that PEI can indicate whether there is a paging message in M POs at the same time, and UEs in each PO may be divided into G subgroups. When each PO is divided into G subgroups, corresponding to 2 G There are M POs in total. GM Possible, for example, G = 4, M = 8, corresponding to 2 GM =2 32 In this case, two solutions are easy to think of for sequence-based PEI. Solution 1, Design 2 GM The terminal needs to detect which sequence the base station is currently transmitting. At this time, the terminal blind detection complexity is extremely high, and the probability of false alarm is extremely high, which cannot be adopted in actual operation. Solution 2: The base station allocates 2 GM Each resource transmits a sequence representing a group within a PO, which results in a huge waste of resources and cannot be adopted. Therefore, it will be a huge challenge for Sequence-based PEI to support multiple POs and each PO to support multiple UE groups. The embodiment of the present application proposes a solution to this problem.

[0191] In the first embodiment, the base station notifies the terminal using high-level signaling or configures the number of user groups G1 included in each paging opportunity and / or the number of paging opportunities N1 included in the paging opportunity group corresponding to a PEI transmission resource through a method preset by the protocol. For example, the base station configures the number of UE groups corresponding to each PO for the terminal using SI (System Information), such as G1=8; and presets the PEI to be PF (Paging Frame) specific through the protocol, that is, each PF frame corresponds to a PEI. Assuming that the number of paging opportunities N1 in a PF frame is N1=4, the corresponding PO group contains N1=4 POs.

[0192] The energy-saving signal / information corresponding to a PEI sending resource is divided into multiple groups with a group number of G2, for example, G2=4 or 5. Each energy-saving signal / information preferably corresponds to a sequence, such as a gold sequence or an orthogonal sequence, and it is not ruled out that it may also be some bits in the DCI used for energy-saving purposes. The explanations about energy-saving signals / information in the subsequent descriptions are the same as here, and other embodiments will not be repeated. If G2=N1=4, each paging opportunity corresponds to a group of energy-saving signals / information; if G2=N1+1, each paging opportunity corresponds to a group of energy-saving signals / information, and there is also a common energy-saving signal / information corresponding to all paging opportunities.

[0193] The aforementioned energy-saving signal / information grouping method may be pre-defined by the protocol or notified to the terminal by the base station via higher-layer signaling. For example, assuming each energy-saving signal / information corresponds to a sequence, the sequence or the scrambling sequence corresponding to the sequence will be assigned to different energy-saving signal / information groups based on the associated paging opportunity information. Each energy-saving signal / information group may contain energy-saving signals / information for one or more paging opportunities. More specifically, the PEI sequence may also be a function of the energy-saving signal / information group ID (identifier), such as a simple linear function.

[0194] The group of energy-saving signals / information corresponding to each paging opportunity can be further divided into subgroups G3, where G3 is greater than or equal to G1, the number of user groups included in each paging opportunity. Specifically, when G3 = G1, preferably, one group of UEs in each paging opportunity corresponds to / is associated with one subgroup of energy-saving signals / information. When G3 > G1, preferably, G3 = G1 + 1. In addition to one group of UEs in each paging opportunity corresponding to / is associated with one subgroup of energy-saving signals / information, there is also a common energy-saving signal / information in a paging opportunity that corresponds to all groups in the paging opportunity.

[0195] The following uses sequence-based PEI to more specifically illustrate the energy-saving signal construction, grouping, and corresponding behaviors on the base station side and the terminal side.

[0196] Assume that one PEI sending resource corresponds to N1 paging opportunities, and sequence-based PEI contains T sequences. Preferably, the sequence is a gold sequence or other pseudo-random sequence or orthogonal sequence. These T sequences used for PEI are divided into G2=N1+1=5 groups, where the first group contains one PEI sequence Seq_com, which is a group of common PEI sequences corresponding to or associated with all paging opportunities; the second group to the G2=5th group preferably contain an equal number of sequences, that is, G3 sequences. Of course, the number of sequences contained in the second to fifth groups may also vary. Each paging opportunity corresponds to a group of PEI sequences, that is, the 2nd, 3rd, 4th,...G2=5th groups of PEI sequences correspond to or are associated with different paging opportunities.

[0197] The set of PEI sequences corresponding to each paging opportunity can be further divided into G3=G1 subgroups, or G3=G1+1 subgroups, where G1 is the number of user groups contained in each paging opportunity. When the PEI sequences corresponding to each paging opportunity are divided into G1 subgroups according to the number of user groups contained in each paging opportunity, each sequence subgroup corresponds to or is associated with a user group in the paging opportunity; when the PEI sequences corresponding to each paging opportunity are divided into G1+1 subgroups, a user group in the paging opportunity will be associated with one of the above sequence subgroups, that is, at this time, G1 user groups in each paging opportunity will correspond to G1 sequence subgroups; in addition, in this case, there is also a common sequence subgroup corresponding to all user subgroups in the paging opportunity. Of course, in actual applications, this common sequence subgroup can also correspond to some user subgroups in the paging opportunity.

[0198] Figure 4 This section describes the situation where the PEI sequences corresponding to each paging opportunity are divided into G1+1 groups. Assume that the total number of PEI sequences is 37, divided into five groups. The first group contains a PO group-specific (paging opportunity group-specific) common energy-saving signal / information Seq_com, and the second through fifth groups each contain nine sequences. The PEI sequences corresponding to each paging opportunity are further divided into nine subgroups, each with only one sequence. One subgroup corresponds to the PO-specific common energy-saving signal / information Seq_PO_0, and the other eight subgroups correspond to UE subgroup-specific energy-saving signals / information Seq_i, where i = 1, ..., 8.

[0199] At this time, the base station processes as follows: as long as there are users in two or more POs in the current paging opportunity group who need to be paged, the base station sends a PO group specific, i.e., a public energy-saving signal / information exclusive to the PO group, on the PEI resource; when there is only one UE in a PO in the paging opportunity group who needs to be woken up, it is divided into two cases: 1) If there are two or more UE groups in the 8 UE groups in the PO who need to be paged, the base station sends a PO specific, i.e., a public energy-saving signal / information exclusive to the PO; 2) If only one of the 8 UEs in the PO needs to be paged, the base station sends a UE subgroup specific, i.e., a UE group-exclusive energy-saving signal / information corresponding to the UE group in the PO.

[0200] Accordingly, the terminal processes as follows: the terminal detects at least one of the PO group specific common energy saving signal / information, the PO specific common energy saving signal / information, and the UE subgroup specific energy saving signal / information in the PEI transmission resource. The terminal will detect at most three sequences.

[0201] If the terminal detects the UE subgroup specific energy-saving signal / information within the PO energy-saving signal group to which it corresponds, the UE needs to receive a paging message within the corresponding PO. The UE subgroup specific energy-saving signal / information indicates that a user group within the corresponding PO receives the corresponding paging message. If the terminal detects the PO specific public energy-saving signal / information corresponding to the PO to which it corresponds, the terminal needs to receive the paging message in the subsequent PO. In fact, since this energy-saving information is common to all user groups corresponding to the PO, the PO specific public energy-saving signal / information can indicate that all user groups within the PO need to receive the corresponding paging message. If the terminal detects the PO group specific public energy-saving signal / information on the resource corresponding to the PEI, the terminal detects the paging message on the corresponding PO. In fact, since this energy-saving information is common to all UE groups in the PO group, the PO group specific public energy-saving signal / information can indicate that all user groups corresponding to the PO group receive the corresponding paging message.

[0202] Through the above embodiments, it is possible to flexibly indicate that all user groups corresponding to all PO groups, all user groups corresponding to a PO, or a specific user group within a PO group receives paging messages within the corresponding PO. Furthermore, the base station only sends one sequence-based PEI sequence at a time within the PEI resource, and the terminal detects a maximum of three sequences within the corresponding PEI resource. This ensures that the PEI system overhead on the base station side is minimal, while the detection performance on the terminal side is excellent and the blind detection complexity is minimized.

[0203] The following further explains the analysis of the excellent performance and feasibility of this solution. According to statistics from base station manufacturers, the average paging probability (paging rate) corresponding to PO is 10%. Assuming paging rate X = 10%, the probability of paging in multiple PO groups can be calculated, as shown in Table 1 below:

[0204] Table 1

[0205]

[0206]

[0207] As shown in Table 1, the probability of more than one PO within a PO group being paged is very low. If the UEs corresponding to two POs need to be paged simultaneously, the base station only sends a PO group-specific public energy-saving signal / information. This results in only a 4.86% probability of falsely waking up the other two POs and a 0.36% probability of falsely waking up the other PO. This is completely acceptable and avoids the conventional mechanism of paying a huge price for little gain. Table 2 shows the paging probabilities for different sub-groups when the PO paging rate X = 10% and the next PO corresponding to 8 UEs is grouped at 40%. (Let the probability of each UE subgroup corresponding to the PO be paged be Y, then 1-(1-Y)^N = X, where N represents the number of sub-groups.)

[0208] Table 2

[0209]

[0210] Table 2 shows that, regardless of the paging rate, for multiple UE groups corresponding to a PO, the base station will most likely page only one UE group within a PO. Therefore, when two or more UE groups corresponding to a PO need to be paged, the false alarm probability caused by the base station sending PO-specific public energy-saving signals / information is negligible. Because only a single PEI sequence is sent within the PEI resource, terminal detection performance is guaranteed, while ensuring minimal overhead on the base station side, minimizing the impact on legacy UEs, and enabling flexible indication.

[0211] In the first embodiment described above, Figure 4 The description describes the situation where the PEI sequences corresponding to each paging opportunity are divided into G1+1 groups. In fact, considering that there is already a public energy-saving signal that can wake up all PO UEs to receive paging messages, the number of PEI sequence groups corresponding to each paging opportunity can also be the same as the number of UE groups corresponding to the PO, that is, the two correspond one to one (of course, it is not ruled out that the number of PEI sequence groups corresponding to each paging opportunity can also be less than the number of UE groups corresponding to the PO). In the second embodiment, it is assumed that the total number of PEI sequences is 33, which are divided into 5 groups. The first group contains a PO group-specific public energy-saving signal / information Seq_com, and the second to fifth groups each contain 8 sequences. The PEI sequence corresponding to each paging opportunity is divided into 8 subgroups, and each subgroup has only one sequence UE subgroup specific energy-saving signal / information Seq_i, i=1,...8.

[0212] At this time, the base station processes as follows: as long as there are users in two or more POs in the current paging opportunity group who need to be paged, or there are more than two groups in a PO that need to be paged, the base station sends a PO groupspecific public energy-saving signal / information on the PEI resource; when there is only one UE in a PO that needs to be woken up in the paging opportunity, if only one of the 8 UEs in the PO needs to be paged, the base station sends a UE subgroup specific energy-saving signal / information corresponding to the UE group in the PO.

[0213] At this time, the terminal processes as follows: the terminal detects at least one of the PO group-specific public energy-saving signal / information and the UE subgroup specific energy-saving signal / information within the PEI sending resource, and detects up to two. If the terminal detects the UE subgroup specific energy-saving signal / information within the PO energy-saving signal group to which it corresponds, the UE group within the PO corresponding to the UE subgroup specific energy-saving signal / information needs to receive a paging message in the subsequent PO, and the UE subgroup specific energy-saving signal / information will only instruct one user group within the PO to receive the corresponding paging message. If the terminal detects a PO group-specific public energy-saving signal / information on the corresponding resource of PEI, the terminal detects the paging message on the corresponding PO. In fact, since this energy-saving information is common to all UE groups in the PO group, the PO group-specific public energy-saving signal / information can instruct all user groups corresponding to the PO group to receive the corresponding paging message.

[0214] In this embodiment, the energy-saving signals corresponding to each paging opportunity can be grouped and degenerated into a single sequence. In this case, each paging opportunity corresponds to a PEI sequence, and the PEI does not provide subgrouping indication for UEs within the PO. In this case, the base station can carry the subgrouping information in other signals, for example, using the reserved bit of the paging DCI to indicate the subgrouping information of the UE corresponding to the PO.

[0215] In this embodiment, the terminal only needs to detect two PEI sequences at most, which is beneficial to reducing the false alarm probability of sequence detection and its detection complexity.

[0216] The previous two embodiments target a typical application scenario with a paging rate of 10%. Although a paging rate of 10% represents the average paging probability, in actual transmission, short bursts of paging may occur, causing the paging probability to suddenly increase. System design should include a solution for this situation. Assume that in the third embodiment, the architecture of the energy-saving signal grouping method can be the same as described in the previous embodiments. Here, the architecture described in the aforementioned "first embodiment" will be used for description. Assume that in the third embodiment, the total number of PEI sequences is 37, divided into five groups. The first group contains a PO group-specific common energy-saving signal / information Seq_com. Groups two through five each contain nine sequences. The PEI sequence corresponding to each paging opportunity is further divided into nine subgroups, each with only one sequence. One subgroup corresponds to the PO-specific common energy-saving signal / information Seq_PO_0, and the other eight subgroups correspond to UE subgroup-specific energy-saving signals / information Seq_i, where i = 1, ..., 8.

[0217] The base station processes the following: As long as there are users in three or more POs within the current paging opportunity group who need to be awakened, the base station sends a PO group-specific public energy-saving signal / information on the PEI resource. When only one UE in a PO within the paging opportunity group needs to be awakened, there are two cases: 1) If two or more of the eight UE groups within the PO need to be paged, the base station sends a PO-specific public energy-saving signal / information. 2) If only one of the eight UEs in the PO needs to be paged, the base station sends a UE subgroup-specific energy-saving signal / information corresponding to the UE group within the PO. When there are UEs in two POs within the paging opportunity group who need to be awakened, a corresponding PEI sequence is required for each PO. In this case, the base station sends two PEI sequences in total. For each PEI sequence, if two of the eight UE groups within the PO need to be paged, the base station sends a PO-specific public energy-saving signal / information. If only one of the eight UEs in the PO needs to be paged, the base station sends a UE subgroup-specific energy-saving signal / information corresponding to the UE group within the PO. The base station preferably sends two PEI sequences simultaneously on one PEI resource. Optionally, the base station can send two PEI sequences on two PEI resources in FDD or TDD mode. Sending two PEI sequences on the same PEI resource will result in poor terminal detection performance, but low system overhead. Sending PEI sequences on two PEI resources will result in good terminal detection performance, but will incur overhead.

[0218] At this point, the terminal processes as follows: the terminal detects at least one of the following: a PO group-specific public energy-saving signal / information, a PO-specific public energy-saving signal / information, and a UE subgroup-specific energy-saving signal / information within the PEI transmission resource. The terminal will detect up to three sequences. If the terminal detects a UE subgroup-specific energy-saving signal / information within its corresponding PO energy-saving signal group, the UE needs to receive a paging message within the corresponding PO. The UE subgroup-specific energy-saving signal / information will only instruct one user group within the corresponding PO to receive the corresponding paging message. If the terminal detects the PO-specific public energy-saving signal / information corresponding to the PO to which it corresponds, the terminal needs to receive paging messages in subsequent POs. Since this energy-saving information is common to all user groups corresponding to the PO, the PO-specific public energy-saving signal / information can indicate that all user groups corresponding to the PO receive corresponding paging messages; if the terminal detects the PO group-specific public energy-saving signal / information on the PEI corresponding resource, the terminal detects the paging message on the corresponding PO. Since this energy-saving information is common to all UE groups in the PO group, the POgroup-specific public energy-saving signal / information can indicate that all user groups corresponding to the PO group receive corresponding paging messages.

[0219] The following describes the beneficial effects and feasibility of this embodiment. According to statistics from base station manufacturers, the paging rate X corresponding to PO is 20%. The probability of paging in multiple PO groups can be calculated as shown in Table 3 below:

[0220] Table 3

[0221] 1 PEI to 4 PO Calculation formula Paging rate 1 PO exists paging <![CDATA[C4 1 *0.2*0.8^3]]> 16.4％ 2 POs have paging <![CDATA[C4 2 *0.2^2*0.8^2]]> 15.36％ 3 POs have paging <![CDATA[C4 3 *0.2^3*0.8]]> 2.56％ 4 POs exist paging 0.2^4 0.16％ No PO exists paging 0.8^4 40.96％

[0222] As can be seen from Table 3, under higher paging probabilities, there is a high probability that two POs will be awakened. Therefore, the method of this embodiment can indicate through the PEI sequence that the UEs corresponding to one PO, two POs, or all POs are paged. Therefore, the indication method in this embodiment is more flexible and can reduce the probability of false paging when the paging probability is high, so that the terminal can obtain higher energy-saving gains. In this embodiment, the base station side may send two sequence-based PEI sequences each time within one PEI resource, which may cause the terminal detection performance to lose more than 3dB. However, considering that the performance of sequence-based PEI is more than 5dB better than that of DCI-based PEI, even if the base station sends two PEI sequences at the same time, it can still ensure that the performance of sequence-based PEI is better than that of DCI-based PEI.

[0223] In one embodiment of the present application, the application scenario is a scenario with a higher paging rate, for example, paging rate = 40%. This scenario is a relatively extreme scenario with a relatively low probability of occurrence. The architecture of the energy-saving signal grouping method can be as described in the aforementioned embodiment. Here, the architecture of the first embodiment is taken as an example. Assume that, in the fourth embodiment, the total number of PEI sequences is 37, which are divided into 5 groups. The first group contains a PO group specific public energy-saving signal / information Seq_com, and the second to fifth groups each contain 9 sequences. The PEI sequence corresponding to each paging opportunity is divided into 9 subgroups, and each subgroup has only one sequence. One subgroup corresponds to the PO specific public energy-saving signal / information Seq_PO_0, and the other 8 subgroups correspond to UE subgroup specific energy-saving signals / information Seq_i, i = 1, ...8.

[0224] At this time, the base station processes as follows: the base station sends a PO group-specific public energy-saving signal / information on the PEI resource only when there are users in 4 POs in the current paging opportunity group who need to be awakened; when there is only one PO corresponding to the UE in the paging opportunity group that needs to be awakened, the base station sends a PEI sequence on the PEI resource; when there are two POs corresponding to the UE in the paging opportunity group that need to be awakened, the base station sends two PEI sequences on the PEI resource; when there are three POs corresponding to the UE in the paging opportunity group that need to be awakened, the base station sends three PEI sequences on the PEI resource; when there are four POs corresponding to the UE in the paging opportunity group that need to be awakened, the base station sends a PO group-specific public energy-saving sequence on the PEI resource. When the PEI sequence is not a PO group-specific public energy-saving sequence: if two of the 8 UE groups in the corresponding PO need to be paged, the PEI sequence is a PO-specific public energy-saving signal / information; if only one of the 8 UEs in the PO needs to be paged, the PEI sequence is a UE subgroup-specific energy-saving signal / information corresponding to the UE group in the PO. The base station preferably sends two PEI sequences simultaneously on one PEI resource. Optionally, the base station may send PEI sequences on multiple PEI resources in an FDD or TDD manner.

[0225] At this point, the terminal processes as follows: the terminal detects at least one of the following: a PO group-specific public energy-saving signal / information, a PO-specific public energy-saving signal / information, and a UE subgroup-specific energy-saving signal / information within the PEI transmission resource. The terminal will detect up to three sequences. If the terminal detects a UE subgroup-specific energy-saving signal / information within its corresponding PO energy-saving signal group, the UE needs to receive a paging message within the corresponding PO. The UE subgroup-specific energy-saving signal / information will only instruct one user group within the corresponding PO to receive the corresponding paging message. If the terminal detects the PO-specific public energy-saving signal / information corresponding to the PO to which it corresponds, the terminal needs to receive paging messages in subsequent POs. Since this energy-saving information is common to all user groups corresponding to the PO, the PO-specific public energy-saving signal / information can indicate that all user groups corresponding to the PO receive corresponding paging messages; if the terminal detects the PO group-specific public energy-saving signal / information on the PEI corresponding resource, the terminal detects the paging message on the corresponding PO. Since this energy-saving information is common to all UE groups in the PO group, the POgroup-specific public energy-saving signal / information can indicate that all user groups corresponding to the PO group receive corresponding paging messages.

[0226] The following further illustrates the beneficial effects and feasibility of this solution. According to statistics from base station manufacturers, the paging rate X corresponding to PO is 40%. The probability of paging in multiple PO groups can be calculated, as shown in Table 4 below.

[0227] Table 4

[0228] 1 PEI to 4 PO Calculation formula Paging rate 1 PO exists paging <![CDATA[C4 1 *0.4*0.6^3]]> 34.56％ 2 POs have paging <![CDATA[C4 2 *0.4^2*0.6^2]]> 34.56％ 3P exists paging <![CDATA[C4 3 *0.4^3*0.6]]> 15.36％ 4 POs exist paging 0.4^4 2.56％ No PO exists paging 0.6^4 12.96％

[0229] As can be seen from Table 4, under extremely high paging probability, there is a high probability that three POs will be awakened. Therefore, the method of this embodiment can indicate that 1 PO, two POs, three POs and the UEs corresponding to all their POs are paged through the PEI sequence. Therefore, compared with the aforementioned embodiment, the indication of this embodiment is more flexible. When the paging probability is extremely high, the probability of false paging can be reduced, so that the terminal can obtain a higher energy-saving gain. However, in this embodiment, in order to avoid the base station using a higher transmission power or allocating more transmission resources, the base station can adopt the method of the third embodiment or the first embodiment, that is, the same resource sends a maximum of two PEI sequences or one PEI sequence, which avoids the problem that the base station needs to send a large number of PEI sequences.

[0230] In the above embodiments, when there is only one paging opportunity in a paging opportunity group, the energy-saving signal / information corresponding to one PEI transmission resource is divided into multiple groups with a group number of G2, that is, G2 = N1 = 1, that is, the number of PEI sequence groups is equal to the number of POs, and then there is no PEI group associated with all paging opportunities. Otherwise, the energy-saving signal / information corresponding to one PEI transmission resource is divided into multiple groups with a group number of G2, G2 = N1 + 1, that is, there is one PEI group associated with all paging opportunities, and the number of other PEI sequence groups corresponds one-to-one with the POs; or, the energy-saving signal / information corresponding to one PEI transmission resource is divided into multiple groups with a group number of G2, there is one PEI group associated with all paging opportunities, and there is also one PEI sequence group associated with a subset of POs within the PO group.

[0231] In the above embodiment, when the PO group contains multiple POs, if two or more UEs in POs need to be awakened at the same time, the base station side will send a public energy-saving signal exclusive to the PO group to wake up all users in all POs. Then, when two UEs in POs need to be awakened at the same time, the base station side may not send the PO group public energy-saving signal, but send the energy-saving signal corresponding to each PO, such as the energy-saving signal exclusive to the sub-group in the PO or the public energy-saving signal exclusive to the PO. In this way, if the base station transmission power allows, the probability of the terminal being mistakenly awakened can be further reduced, and terminal energy saving can be promoted. When Threshold>=3, that is, when three or more terminals in POs need to be awakened at the same time, the base station will send a public energy-saving signal exclusive to the PO group. The Threshold>=3 is only for illustration. In actual applications, other values can also be used, and corresponding values can also be used depending on the implementation of the base station.

[0232] Taking the scenario where one PEI corresponds to 4 POs and each PO corresponds to 8 UE groups as an example, from the perspective of DCI, it actually corresponds to 32 bits, that is, there are 2^32 possibilities. Therefore, requiring the base station to indicate so many transmission possibilities and maintain excellent performance on the base station side and the terminal side is a task that cannot be completed with the existing technology. Through the solution of the embodiment of the present application, the problem of requiring the sequence-based PEI to indicate all candidate possibilities is avoided, the overhead on the base station side is reduced, the detection complexity on the terminal side is reduced, and the detection performance of the terminal is improved without significantly losing the energy-saving gain of the terminal. Compared with the candidate solution DCI based PEI, it can effectively respond to paging of terminals under different paging probabilities, maintain a compromise between the overhead on the base station side and the energy-saving gain on the terminal side, and has the advantages of high efficiency, good performance and good flexibility.
