Description

Method, terminal equipment and network equipment for determining paging group Technical field

This application relates to the field of communications, and more specifically, to a method, terminal device, and network device for determining a paging packet.

Background technique

The main function of paging (Paging) is to enable the network to be in the RRC IDLE state or RRC INACTIVE state of the user equipment (UE, User Equipment) through paging messages. Call the UE, or notify the UE of system message changes or earthquake and tsunami/public warning information through a short message (applicable to all RRC states of the UE, including the connected state).

For the UE in the RRC IDLE state or RRC INACTIVE state, because there is no other data communication between the UE and the network, in order to save energy, the UE can monitor the paging channel non-continuously, that is, use paging DRX (paging Discontinuous Reception). )mechanism. Under the paging DRX mechanism, the UE only needs to monitor paging during one paging occasion (PO, Paging Occasion) in each DRX cycle (DRX cycle). There are many UEs in the system, and when the network cannot allocate each UE to a different PO, there will be a situation where multiple UEs correspond to one PO. If the network needs to page a certain UE on this PO, it may cause other UEs that do not originally have paging messages to perform additional blind detection. For these UEs that do not originally have paging messages, this additional blind detection is a paging false alarm. .

In the following, specific embodiments will be described in detail with reference to the accompanying drawings.

Example one:

The network device configures multiple paging resources, and each paging resource configuration corresponds to different paging packets (paging packets) of the same PO, and is used to send paging information to UEs that are mapped to different paging packets of the same PO. At the same time, the network device assigns a weight to each paging group, such as a terminal distribution weight; in the following embodiments, the terminal distribution weight of the paging group is denoted as W(i), where i is the index of the paging group. The UE can determine its own corresponding paging group according to the identification (UE ID) of each terminal device and the weight of the paging group. The method is as follows: the weight of each paging group does not exceed the proportion of the number of UEs determined by the weight. In this case, the paging group corresponding to the smaller index number is preferentially selected. When the number of UEs mapped to the paging group with a small corresponding index number reaches the distribution ratio of the number of UEs determined by the weight, the UE selects the paging group corresponding to the next index number. It includes the following steps:

Step 1: The UE receives network configuration information and configures Paging related parameters, which specifically include:

a) Multiple paging resources are configured, and the multiple paging resources are respectively used to send paging information to UEs in different paging groups mapped to the same PO. The multiple Paging resources determined by the configuration information have the following characteristics:

1) For one PO, each paging resource in the multiple paging resources corresponds to S consecutive PDCCH monitoring occasions. Among them, S is the actual number of SSB sent by the network broadcast;

2) The method for distinguishing the multiple groups of paging resources may be at least one of the following methods:

-Method 1: Multiple groups of paging resources corresponding to the same PO do not overlap each other in the time domain;

-Method 2: Multiple groups of paging resources corresponding to the same PO do not overlap each other in the frequency domain;

3) Assuming that the number of paging groups is Nn (Nn>1), the number of paging resource configurations is:

-Method 1: Configure Nn paging resources

-Method 2: Configure Nn+1 paging resources

b) Determine the corresponding relationship between the configured groups of paging resources and Nn paging groups through a predefined or network configuration method:

-Case 1: For the case where Nn paging resources are configured

The Nn paging resources have a one-to-one correspondence with the Nn paging groups. For UEs without paging group information (such as Rel-15/16 version UEs), it corresponds to a default paging resource (such as the first paging resource).

-Case 2: For the case where Nn+1 paging resources are configured

For UEs without paging group information (such as Rel-15/16 version UEs), it corresponds to the first paging resource.

For UEs with paging group information, the indexes of the paging group are respectively 2 to Nn+1, and the second to Nn+1th paging resources respectively correspond to paging groups with indexes 2 to Nn+1 in a one-to-one correspondence.

c) Configure a weight W(i) for each paging group, where i is the index of the paging group. The weight W(i) is used to determine the distribution ratio of the number of UEs mapped to different paging groups. The larger W(i), the more UEs mapped to the paging group. W(i) is a positive integer.

-Case 1: For the case where Nn paging resources are configured:

Nn paging resources correspond to paging groups with indexes 1 to Nn respectively, and each paging group is configured with a weight W(i), where i=1, 2, ..., Nn.

-Case 2: For the case where Nn+1 paging resources are configured:

The second to Nn+1th paging resources correspond to paging groups with indexes 2 to Nn+1 respectively, and each paging group is configured with a weight W(i), where i=2, 3,..., Nn+1.

Step 2: The UE determines its own paging group based on the UE ID and the weight W(i) of each paging group. The method is as follows:

a) For a Rel-15/16 version UE, determine that the UE belongs to the first paging group.

b) For Rel-17 and subsequent versions of UE:

-Case 1: For the case where Nn paging resources are configured

The paging group index corresponding to the UE is the smallest index n (1≤n≤Nn) that satisfies the following conditions.

floor(UE_ID/(N*Ns))mod W<W(1)+W(2)+…+W(n)

Among them, UE_ID is 5G-S-TMSI mod 1024, N is the number of PFs in a paging DRX cycle, Ns is the number of POs in a PF, W(n) is the weight of paging group n, and W is all Nn The sum of the weights corresponding to each paging group, namely W=W(1)+W(2)+…+W(Nn)

-Case 2: For the case where Nn+1 paging resources are configured

The paging group index corresponding to the UE is the smallest index n (2≤n≤Nn+1) that satisfies the following conditions.

floor(UE_ID/(N*Ns))mod W<W(2)+W(3)+…+W(n)

Among them, UE_ID is 5G-S-TMSI mod 1024, N is the number of PFs in a paging DRX cycle, Ns is the number of POs in a PF, W(n) is the weight of paging group n, and W is all paging The sum of the weights corresponding to the group (that is, the paging group with an index of 2 to Nn+1), that is, W=W(2)+W(3)+…+W(Nn+1)

Step 3: The UE monitors the paging channel on the PO. specifically,

For a UE with paging group information, it monitors the PDCCH scrambled by the P-RNTI on the paging resource corresponding to the paging group to which it belongs.

For a UE without paging group information, it monitors the PDCCH scrambled by the P-RNTI on a default paging resource.

The foregoing paging resource includes multiple PDCCH monitoring occasions.

FIG. 4 is a schematic diagram of the effect of determining paging grouping in the first embodiment of the application. As shown in Figure 4, one PO corresponds to 3 paging groups, the indexes of which are 2, 3, and 4, and the terminal distribution weights are 1, 3, and 2, respectively. Configure 4 paging resources, the indexes of which are 1, 2, 3, and 4 respectively. Among them, paging resources 2, 3, and 4 correspond to paging groups 2, 3, and 4 respectively, and paging resource 1 is used to send to UEs that do not have paging group information. Paging information.

In this embodiment, it is assumed that the number of PFs included in one paging DRX cycle is one, and the number of POs included in one PF is one. According to the above configuration, UEs with UE ID=0 belong to paging group 2, UEs with UE ID=1, 2, 3 belong to paging group 3, UEs with UE ID=4, 5 belong to paging group 3, and so on. As shown in Figure 4, the ratio of the number of UEs in the three paging groups is 1:3:2, which is consistent with the distribution ratio specified by the terminal distribution weight.

For different UEs, the network device sends the paging information of the UE on the paging resource corresponding to the paging group to which the UE belongs; accordingly, the UE monitors the paging resource corresponding to the paging group to which it belongs, thereby reducing unnecessary The paging is received.

Embodiment two:

The network device configures multiple paging resources, and each paging resource configuration corresponds to different paging packets (paging packets) of the same PO, and is used to send paging information to UEs that are mapped to different paging packets of the same PO. At the same time, the network device assigns a weight to each paging group, such as a terminal distribution weight; in the following embodiments, the terminal distribution weight of the paging group is denoted as W(i), where i is the index of the paging group. The UE can determine its own corresponding paging group according to the identification (UE ID) of each terminal device and the weight of the paging group. The method is as follows: the weight of each paging group does not exceed the proportion of the number of UEs determined by the weight. In this case, the priority is based on the principle of fairness and is mapped to each paging group that meets the above conditions in the order of the UE ID from small to large, that is, the UE is first mapped to each of the corresponding weights not less than 1 in the order of the UE ID from small to large. The paging grouping, after completing the traversal of all paging groups with a corresponding weight of not less than 1, then sequentially map to each paging group with a corresponding weight of not less than 2, and so on. It includes the following steps:

Step 1: The UE receives network configuration information and configures Paging related parameters. This step is the same as Step 1 of Embodiment 1, and will not be repeated here.

Step 2: The UE determines its own paging group based on the UE ID and the weight W(i) of each paging group. The method is as follows:

a) For a Rel-15/16 version UE, determine that the UE belongs to the first paging group.

b) For Rel-17 and subsequent versions of UE:

First determine the minimum k (the maximum value of 1≤k≤W(i)) that satisfies the following conditions

floor(UE_ID/(N*Ns))mod W<W(i) The number of paging groups that are not less than 1

+W(i) The number of paging groups not less than 2+...

+W(i) The number of paging groups not less than k

Then, determine j according to the above k, and the determination method is:

If k=1, then j=floor(UE_ID/(N*Ns))mod W+1

If k>1, then j=floor(UE_ID/(N*Ns))mod W-M+1;

in,

M=W(i) The number of paging groups not less than 1+

…+

W(i) is not less than the number of paging groups of k-1

Finally, according to the above k and j, it is determined that the paging group index n corresponding to the UE is: W(i) is not less than the index corresponding to the jth paging group in the paging group of k.

Among them, UE_ID is 5G-S-TMSI mod 1024, N is the number of PFs in a paging DRX cycle, Ns is the number of POs in a PF, W(n) is the weight of paging group n, and W is all Nn The sum of the weights corresponding to each paging group.

For the case where the indexes of Nn paging groups are respectively 1 to Nn, W=W(1)+W(2)+...+W(Nn);

For the case where the indexes of Nn paging packets are respectively 2 to Nn+1, W=W(2)+W(3)+...+W(Nn+1).

Step 3: The UE monitors the paging channel on the PO. The specific method is the same as step 3 of the first embodiment, and will not be repeated here.

FIG. 5 is a schematic diagram of the effect of determining paging grouping in the second embodiment of the application. As shown in Figure 5, one PO corresponds to 3 paging groups, the indexes of which are 2, 3, and 4, and the terminal distribution weights are 1, 3, and 2, respectively. Configure 4 paging resources, the indexes of which are 1, 2, 3, and 4 respectively. Among them, paging resources 2, 3, and 4 correspond to paging groups 2, 3, and 4 respectively, and paging resource 1 is used to send to UEs that do not have paging group information. Paging information.

In this embodiment, it is assumed that the number of PFs included in one paging DRX cycle is one, and the number of POs included in one PF is one. According to the above configuration, UEs with UE ID=0, 1, and 2 belong to paging groups 2, 3, and 4, respectively, UEs with UE ID=3 and 4 belong to paging groups 3 and 4, respectively, and UEs with UE ID=5 belong to paging group 3. , And so on. As shown in FIG. 5, the ratio of the number of UEs in the three paging groups is 1:3:2, which is consistent with the distribution ratio specified by the terminal distribution weight.

For different UEs, the network device sends the paging information of the UE on the paging resource corresponding to the paging group to which the UE belongs; accordingly, the UE monitors the paging resource corresponding to the paging group to which it belongs, thereby reducing unnecessary The paging is received.

The embodiment of the present application also proposes a method for determining a paging group. FIG. 6 is an implementation flowchart of a method 600 for determining a paging group according to an embodiment of the present application, including the following steps:

S610: The network device uses the terminal distribution weight of each paging packet and/or the terminal device identifier to determine the paging packet to which the terminal device belongs.
