[0084] To facilitate understanding of the technical solutions of the embodiments of the present invention, the key technologies involved in the embodiments of the present invention are explained below.

[0085] 1) Beamforming in 5G

[0086] Since the frequency band used by the 5G system is higher than that of the LTE system, the path loss of the wireless signal transmission of the 5G system is also greater than that of the LTE system, resulting in a smaller coverage range of the wireless signal of the 5G system. For this reason, in the 5G system, the multi-antenna system of the base station uses beamforming technology to form beams to increase the gain of the wireless signal, thereby compensating for the path loss. In beamforming technology, the beam is directional, and a narrow beam can only cover part of the cell, and cannot cover the entire cell. Figure 1 As shown, the base station can send signals through beams in four different directions (B1, B2, B3, B4). For beam B2, it can only cover UE1 but not UE2.

[0087] 2) SS block (Synchronization Signal block) in 5G

[0088] Public channels and public signals in the 5G system, such as broadcast channels and synchronization signals, need to cover the entire cell through multi-beam scanning so that UEs in the cell can receive these signals. For synchronization signals, the transmission of multiple beams is achieved by defining a synchronization signal burst group (SS burst set). An SS burst set includes one or more synchronization signal bursts (SS bursts), and an SS burst includes one or more SS blocks (also referred to as SSBs). An SS block is used to carry the synchronization signal and broadcast channel of a beam. Therefore, an SS burst set can include the synchronization signals of the number of SS block (SS block number) beams within the cell. For example Figure 2 As shown, one SS block includes one symbol of primary synchronization signal (PSS), one symbol of secondary synchronization signal (SSS) and two symbols of physical broadcast channel (PBCH, Physical Broadcast Channel).

[0089] The number L of SS blocks included in an SS burst set is determined according to the frequency band of the system, for example:

[0090] For the 3 GHz frequency band, L is 4;

[0091] For the 3GHz-6GHz frequency band, L is 8;

[0092] For the frequency band of 6 GHz-52.6 GHz, L is 64.

[0093] For SS burst set, its transmission period is configurable. In an example, SS burst set in one period is sent within a 5ms time window. In addition, the subcarrier spacing (SCS) of the system can also be configured. The time slot distribution under different subcarrier spacing and frequency bands is as follows: Figure 3 As shown, Figure 3 From top to bottom, they show:

[0094] The time slot distribution of SS burst set under 15KHz SCS and L=4 (corresponding to the 3GHz frequency band);

[0095] The time slot distribution of SS burst set under 15KHz SCS and L=8 (corresponding to the frequency band of 3GHz-6GHz);

[0096] The time slot distribution of SS burst set under 30KHz SCS and L=4 (corresponding to 3GHz frequency band);

[0097] The time slot distribution of SS burst set under 30KHz SCS and L=8 (corresponding to the frequency band of 3GHz-6GHz);

[0098] The time slot distribution of SS burst set under 120KHz SCS and L=64 (corresponding to the frequency band of 6GHz-52.6GHz);

[0099] The time slot distribution of SS burst set under 240KHz SCS and L=64 (corresponding to the frequency band of 6GHz-52.6GHz).

[0100] Furthermore, regarding the distribution of SS blocks in a time slot, a time slot includes 14 symbols and can carry at most two SS blocks. The distribution of SS blocks under different subcarrier spacing is as follows: Figure 4 As shown, Figure 4 From top to bottom, they show:

[0101] Distribution of SS blocks in a time slot under 15KHz SCS;

[0102] Distribution of SS blocks in a time slot under 30KHz SCS 1;

[0103] Distribution 2 of SS blocks in a time slot under 30KHz SCS;

[0104] Distribution of SS blocks in a time slot under 120KHz SCS;

[0105] Distribution of SS blocks in a time slot under 240KHz SCS.

[0106] In the above scheme, although the number of SS blocks L is determined according to the frequency band of the system, L is only the maximum number corresponding to the SS block. The number of SS blocks actually sent by the network may be less than L. The number of SS blocks actually sent by the network needs to be indicated to the UE so that the UE can perform rate matching. The time-frequency resource position where the SS block is not sent can be used for transmission of other channels, such as the physical downlink shared channel (PDSCH). Here, the information of the SS block actually sent by the network is indicated by RMSI.

[0107] The predefined time-frequency resources where the SS block is located are distributed in the slot as follows: Figure 5As shown, however, due to the different periods of SS blocks and the different SS blocks actually sent, the SS blocks may not be sent on the predefined time-frequency resources. Therefore, these predefined time-frequency resources are called nominal resources of the SS block.

[0108] 3) LTE Paging

[0109] In the LTE system, the network can send paging to UEs in idle state and UEs in connection state. The paging process can be triggered by the core network or the base station, and is used to send a paging request to the UE in idle state, or to notify the UE of system information update, or to notify the UE to receive information such as earthquake tsunami warning information (ETWS) and commercial mobile warning service (CMAS). After receiving the paging message from the core network, the base station parses the paging message, obtains the UE's tracking area identity list (TA list, Tracking Area Identity list), and performs air interface paging on the cells belonging to the tracking area in the TA list. Furthermore, after receiving the paging message from the core network, the base station aggregates the paging messages with the same PO into one paging message, and transmits it to the relevant UE through the paging channel. The UE receives the paging parameters through the system message, calculates the PO in combination with its own International Mobile Subscriber Identification Number (IMSI), and receives the paging message at the corresponding time according to the PO. Here, the paging message is carried by PDSCH, and the UE obtains the paging indication information by detecting the physical downlink control channel (PDCCH) encrypted with P-RNTI, thereby receiving the paging message in PDSCH. Furthermore, the UE in Idle state will save power through DRX. The UE obtains DRX-related information from SIB2 and listens to the PDCCH encrypted with P-RNTI on the PO in the PF in a DRX cycle to receive the paging message.

[0110] In the above scheme, PF indicates the system frame number on which the paging message should appear, and PO indicates the subframe time when the paging message may appear. A PF frame may include one or more PO subframes. In each DRX cycle or paging cycle, the UE only needs to monitor the PO subframe belonging to it. The distribution of PF and PO is as follows: Figure 6 As shown. A system frame number (SFN) that satisfies the following formula can be used as a PF frame:

[0111] SFN mod T=(T div N)×(UE_ID mod N)

[0112] Where T represents the DRX cycle or paging cycle of the UE. If the default paging cycle carried in SIB2 is recorded as T_sib, if the DRX value T_ue of the UE has been configured, then T = min (T_ue, T_sib), which means taking the smaller value between T_ue and T_sib; if T_ue is not configured, then T = T_sib. UE_ID = (IMSI mod 1024), that is, all IMSIs are divided into 1024 UE groups, and IMSI is unique for each user. N=min(T, nB), which means taking a smaller value between T and nB, where the parameter nB represents the paging density. nB is carried in SIB2 and has a value range of {4T, 2T, T, T / 2, T / 4, T / 8, T / 16, T / 32}, so the value range of N is {T, T / 2, T / 4, T / 8, T / 16, T / 32}; in fact, N represents how many PFs are included in each cycle.

[0113] The position of the PO subframe is determined by the LTE standard type (FDD or TDD), parameters Ns and i_s, where Ns indicates how many paging subframes there are in each PF, i_s indicates the index of the paging subframe, Ns = max(1, nB / T), i_s = floor(UE_ID / N) mod Ns. As shown in Table 1 and Table 2, Ns can only take three values: 1, 2, and 4. For example, if the current standard is LTE-FDD and Ns = 4, then if i_s = 0, then PO = 0, and the paging message will be sent in subframe 0; if i_s = 2, then PO = 5, and the paging message will be sent in subframe 5. Finally, the UE determines the position of its own PO within a cycle based on the PO in the cell and its own UE_ID. In this way, UEs are evenly divided into different POs.

[0118] 4) 5G Paging

[0119] In 5G, the definition of a PO's time-frequency resource is a definition of the nominal resource corresponding to the SS block used to carry the paging message in the PO. Figure 7As shown, at the symbol where the nominalresource of the SS block that is actually sent is located, the time-frequency resources corresponding to the PO and the time-frequency resources corresponding to the nominal resource are frequency-divided, and this type of time-frequency resources corresponding to the PO is called the first time-frequency resource type; at the symbol where the nominalresource of the SS block that is not sent is located, the time-frequency resources corresponding to the PO can include the time-frequency resources corresponding to the nominal resource, and this type of time-frequency resources corresponding to the PO is called the second time-frequency resource type.

[0120] for Figure 7 The two types of time-frequency resources in PO have different capabilities for carrying paging messages due to the different sizes of their time-frequency resources. Especially for the first type of time-frequency resources, since the time-frequency resources corresponding to PO and the time-frequency resources corresponding to nominalresource are frequency-divided, and the total bandwidth is required to meet the minimum bandwidth capability of UE, the bandwidth used to carry paging messages is very limited. At the same time, since paging messages are sent through beam scanning, the overhead is very large. One way to save overhead is to increase the number of UEs that can be paged by each PO, thereby reducing the total number of paging message transmissions. For these two types of time-frequency resource POs, due to the different resource sizes, differentiated paging capabilities can be adopted. In LTE, all UEs (corresponding to UE_ID) are evenly divided into each PO.

[0121] Taking LTE as an example, UE_ID = (IMSI mod 1024), that is, all IMSIs are divided into 1024 UE groups, where the UEs in each UE group correspond to the same UE_ID. Different UE_IDs calculate their POs according to the formula i_s = floor (UE_ID / N) mod Ns, that is, PO = f (UE_ID, N, Ns). In LTE, UE_IDs are evenly distributed in different POs. For example, nB = 32, that is, there are 32 POs in a DRX cycle, and each PO has 1024 / 32 = 32 UE_IDs.

[0122] In the embodiment of the present invention, the distribution of UE_ID in PO is uneven. The technical solution of the embodiment of the present invention is described below in conjunction with a specific embodiment.

[0123] Figure 8 FIG. 1 is a flow chart of a method for determining a paging time according to an embodiment of the present invention. Figure 1 ,like Figure 8 As shown, the method for determining the paging time includes the following steps:

[0124] Step 801: The terminal determines the paging time unit corresponding to the terminal according to the terminal identifier, the configuration parameters of the paging time unit and the preset rules; wherein the paging time unit includes at least a first type of paging time unit and a second type of paging time unit, and different types of paging time units correspond to different preset rules.

[0125] In one implementation, the identifier of the terminal is IMSI. Specifically, the terminal determines the UE_ID of the terminal based on the following function: UE_ID=(IMSI mod S); wherein S represents a preset value and is a positive integer.

[0126] For example, when S=1024, UE_ID=(IMSI mod 1024).

[0127] Further, the terminal determines the paging time unit corresponding to the terminal according to the UE_ID of the terminal, the configuration parameters of the paging time unit and a preset rule.

[0128] In the embodiment of the present invention, different preset rules satisfy the non-uniform distribution of the terminals in different types of paging time units.

[0129] In one implementation, the first type of paging time unit corresponds to a first time-frequency resource type, and the second type of paging time unit corresponds to a second time-frequency resource type.

[0130] In the above solution, the first time-frequency resource type and the second time-frequency resource type are different. Here, the first time-frequency resource type and the second time-frequency resource type are different in that:

[0131] 1) The size of the time-frequency resources corresponding to the first time-frequency resource type is different from the size of the time-frequency resources corresponding to the second time-frequency resource type.

[0132] 2) The multiplexing method of the first time-frequency resource type and the time-frequency resources of the SS block is different from the multiplexing method of the second time-frequency resource type and the time-frequency resources of the SS block.

[0133] 3) The time-frequency resource size corresponding to the first time-frequency resource type is different from the time-frequency resource size corresponding to the second time-frequency resource type; and the multiplexing method of the first time-frequency resource type and the time-frequency resources of the SS block is different from the multiplexing method of the second time-frequency resource type and the time-frequency resources of the SS block.

[0134] In the above solution, the first type of paging time unit corresponds to the first time-frequency resource type, including:

[0135] On the symbol where the nominal resource of the sending SS block is located, the time-frequency resource corresponding to the first type of paging time unit is frequency-divided with the nominal resource.

[0136] In the above solution, the second type of paging time unit corresponds to the second time-frequency resource type, including:

[0137] On the symbol where the nominal resource of the SS block is not sent, the time-frequency resources corresponding to the second type of paging time unit may include the time-frequency resources where the nominal resource is located.

[0138] In the embodiment of the present invention, the paging time unit includes PO, or a part of the time unit in PO.

[0139] In the embodiment of the present invention, the configuration parameters of the paging time unit include at least one of the following: distribution parameters of the terminal on different types of paging time units, and the number of paging time units corresponding to different time-frequency resource types included in a transmission cycle. Further, the terminal obtains the configuration parameters of the paging time unit from the network.

[0140] In one example, nB=nB1+nB2, the terminal determines the paging time unit corresponding to the terminal based on the following function: f(UE_ID, nB1, nB2);

[0141] Among them, the f function represents a preset rule, and UE_ID, nB1, and nB2 are input parameters of the f function (that is, configuration parameters of the paging time unit), which are respectively expressed as follows:

[0142] UE_ID = (IMSI mod 1024);

[0143] nB1 represents the number of paging time units corresponding to the first time-frequency resource type included in a transmission cycle;

[0144] nB2 represents the number of paging time units corresponding to the second time-frequency resource type included in one transmission cycle.

[0145] In the embodiment of the present invention, different preset rules satisfy the uneven distribution of the terminals in different types of paging time units, that is, the number of UE_IDs distributed in each paging time unit in the first time-frequency resource type is different from the number of UE_IDs distributed in each paging time unit in the second time-frequency resource type.

[0146] In addition, the input parameters of the f function (that is, the configuration parameters of the paging time unit) may also include: the distribution parameters of the terminal on different types of paging time units. For example: the total number of paging time units corresponding to the first time-frequency resource type and the total number of paging time units corresponding to the second time-frequency resource type distributed by UE_ID are Nx1 and Nx2 respectively, and Nx2 / Nx1=x. Based on this, there are 1024 / ((1+x)nB1) UE_IDs distributed in each PO in the first time-frequency resource type, and there are 1024x / ((1+x)nB1) UE_IDs distributed in each PO in the second time-frequency resource type.

[0147] The technical solution of the embodiment of the present invention is not limited to the above example, and other methods that can achieve uneven distribution of terminals in paging time units also fall within the protection scope of the embodiment of the present invention.

[0148] For example, there are nB=16 paging time units in a DRX cycle, and UE_ID=(IMSI mod 1024), that is, there are 1024 UE_IDs of the terminal in total. These 1024 UE_IDs are unevenly distributed in the 16 paging time units. In practical applications, a certain number of UE_IDs can be flexibly configured for each paging time unit according to different application scenarios to achieve balanced allocation of paging resources.
