Detailed ways

In order to have a more detailed understanding of the characteristics and technical content of the embodiments of the present application, the implementation of the embodiments of the present application will be described in detail below with reference to the accompanying drawings. The attached drawings are for reference and explanation purposes only, and are not used to limit the embodiments of the present application.

Before describing the embodiments of the present application in detail, the paging (Paging) mechanism in the New Radio (NR) system will be described.

The main function of paging is that when the terminal device is in the radio resource control (Radio Resource Control, RRC) idle state (IDLE) or the RRC deactivated state (INACTIVE), the network device can page the terminal device through a paging message (paging message), or Notify the terminal equipment of system message changes or earthquake and tsunami/public warning information through short messages. Of course, Paging is also applicable to terminal devices in the RRC connected state, that is, Paging is applicable to all terminal devices in the RRC state.

The content of Paging may include PDCCH scrambled by Paging Radio Network Temporary Identifier (P-RNTI), and Physical Downlink Share Channel (PDSCH) scheduled by the PDCCH. The paging message can be transmitted in the PDSCH; the size of the short message is 8 bits, and the short message can be in the PDCCH.

For the terminal device in the RRC_IDLE state or RRC_INACTIVE state, since there is no data communication between the terminal device and the network device, in order to save the power of the terminal device, the terminal device can monitor the Paging channel non-continuously, that is, use Paging Discontinuous Reception (Discontinuous Reception). , DRX) mechanism. Under the paging DRX mechanism, the terminal device only needs to monitor paging during one paging occasion (Paging Occasion, PO) in each DRX cycle (cycle). The PO includes multiple PDCCH monitoring opportunities, and at the same time, the PO can be composed of multiple time slots. A paging frame (Paging Frame, PF) refers to a radio frame, the duration of the FP is 10 ms, and a PF may contain multiple POs or the starting positions of multiple POs.

The DRX cycle is determined by the public cycle in the system broadcast sent by the network equipment and the exclusive cycle configured in the high-level signaling. The terminal equipment can choose the smallest cycle of the two as the DRX cycle; the high-level signaling can be the non-access layer ( Non-Access Stratum, NAS) signaling. From the perspective of a network device, there can be multiple POs in a DRX cycle, and the location where the terminal device monitors the PO is related to the identifier (ID) of the terminal device. Specifically, the method for determining the PF and PO of a terminal device in a DRX cycle is as follows (TS 38.304): The system frame number (System Frame Number, SFN) of the PF is determined by the following formula:

(SFN+PF_offset) mod T = (T div N) * (UE_ID mod N) (1)

The number Index_(i_s) where the PO is located in a PF is determined by the following formula:

i_s=floor(UE_ID/N)mod Ns (2)

Among them, T is the DRX cycle for the terminal device to receive Paging. The network device will broadcast a default DRX cycle; if the network device configures the terminal device with a dedicated DRX cycle for the terminal device through RRC signaling/high-level signaling, the DRX cycle and RRC signaling/high-level signaling that the network device broadcasts The smallest one of the configured DRX cycles dedicated to the terminal device is used as the DRX cycle of the terminal device. If the network device does not configure the terminal device with a dedicated DRX cycle for the terminal device through RRC signaling/high-level signaling, the DRX cycle broadcast by the network device is taken as the DRX cycle of the UE. N is the number of PFs included in a DRX cycle. Ns is the number of POs contained in a PF. PF-offset is the time domain offset used to determine the PF. UE_ID is 5G-S-TMSI mod 1024.

The configuration of the above parameters is as follows:

For any terminal device, according to the above formula (1) and formula (2), the position of the PF and the index of the PO in a DRX cycle can be determined. According to TS 38.304, a PO is composed of multiple PDCCH monitoring occasions. A PO contains X PDCCH monitoring occasions, and X is equal to the synchronization signal block (Synchronization) broadcast in the master information block (Master Information Block, MIB). Signal Block, SSB) actually sent quantity.

After the terminal device determines the PF, the index of the PO, and the number of PDCCH monitoring occasions in the PO, it also needs to determine the starting position of the first PDCCH monitoring occasion of the PO through the configuration parameters sent by the network device; wherein, the starting position may be Obtained through high-level signaling configuration sent by network equipment, or based on PO index. The terminal device blindly checks the Paging message according to the determined PO.

In the R17 project, the 3GPP RAN plenary meeting agreed to a further enhancement project (RP-193239) for energy saving of terminal equipment, which is to reduce the terminal equipment receiving unnecessary paging by designing an enhanced paging mechanism.

In the process of implementing the paging method, the applicant found that there are problems of high system overhead and high energy consumption of terminal equipment; the reason is: when there are more terminal equipment in the system, the network equipment may not allocate each terminal equipment To different POs, there will be multiple terminal devices corresponding to one PO. In this scenario, if a network device needs to page a terminal device on a PO, since the PO may correspond to multiple terminal devices, it may cause the terminal devices that do not need to receive paging messages to perform additional blind inspections, such as blind inspections. PDCCH and PDSCH corresponding to PDCCH. The additional blind detection performed by terminal devices that do not need to receive paging messages can be called paging false alarms. Therefore, how to reduce the system Overhead, reducing the energy consumption of terminal equipment is a problem that needs to be solved.

An optional processing flow of the paging method provided by the embodiment of the present application, as shown in FIG. 2, includes the following steps:

Step S201: The terminal device determines the grouping information of the terminal device.

Wherein, the grouping information is obtained by grouping at least two terminal devices corresponding to one paging occasion. For example, one paging occasion corresponds to N terminal devices, and N is an integer greater than 1. Then, the N terminal devices are grouped, and the terminal devices belonging to the same group can monitor the corresponding PDCCH channel at the same time. The number of packets that can be divided by N terminal devices corresponding to a paging occasion is determined by the network device or predefined. When a paging frame includes multiple paging occasions, the number of groups that can be divided by terminal devices corresponding to the multiple paging occasions may be the same or different.

In some embodiments, the grouping information of the terminal device is configured by the network device. For example, the terminal device receives first configuration information sent by a network device, where the first configuration information is used by the terminal device to determine the grouping information of the terminal device. Wherein, the first configuration information may be carried in a system broadcast message, or may be carried in RRC dedicated signaling.

In other embodiments, the grouping information of the terminal device is predefined.

Step S202: The terminal device determines a paging parameter based on the grouping information, and the paging parameter is used by the terminal device to detect a paging message.

In the embodiment of the present application, the paging parameters may include: the time domain offset (PF_offset) of the paging frame and the PDCCH monitoring timing for the terminal device to detect the paging message.

Hereinafter, the paging method provided in the embodiment of the present application will be described by taking the paging parameter as the time domain offset of the paging frame and the paging parameter as the PDCCH monitoring opportunity for the terminal device to detect the paging message as examples.

In the case that the paging parameter is the time domain offset of the paging frame, an optional processing procedure of the paging method provided in the embodiment of the present application, as shown in FIG. 3, includes:

Step S301: The terminal device determines the grouping information of the terminal device in a predefined manner or through the first configuration information sent by the network device.

In this embodiment of the application, multiple terminal devices corresponding to one PO are divided into N groups, where N is an integer greater than 1.

Step S302: The terminal device receives the third configuration information sent by the network device.

In this embodiment of the present application, the third configuration information is used by the terminal device to determine the number of time domain offsets of the paging frame. Wherein, the third configuration information and the first configuration information may be the same configuration information, or may be different configuration information.

In some embodiments, the number of time domain offsets is equal to the number of groups obtained by grouping terminal devices corresponding to a paging occasion included in the paging frame. If multiple terminal devices corresponding to one PO are divided into N groups, the number of time domain offsets is also N.

In other embodiments, the number of time domain offsets is equal to the number of groups obtained by grouping terminal devices corresponding to a paging occasion included in the paging frame plus one. If multiple terminal devices corresponding to one PO are divided into N groups, the number of time domain offsets is N+1.

In the embodiment of the present application, the third configuration information includes N PF_offsets, which are used by the terminal device to determine the number of time domain offsets to be N; or, the third configuration information includes N+1 PF_offsets, which are used for all PF_offsets. The terminal device determines that the number of time domain offsets is N+1.

In a specific implementation, in addition to being used by the terminal device to determine the number of time domain offsets of the paging frame, the third configuration information may also include at least one of the following :

1) A set of ControlResourceSet and Paging search space;

2) A first PDCCH-Monitoring OccasionOfPO sequence, the first PDCCH-Monitoring OccasionOfPO sequence is used to indicate the first PDCCH monitoring opportunity corresponding to each PO in a PF.

Step S303: The terminal device determines the mapping relationship between the time domain offset of the paging frame and the grouping information.

In some embodiments, the mapping relationship between the time domain offset of the paging frame and the packet information is configured by the network device; for example, the terminal device receives the second configuration information sent by the network device, and the second configuration information includes the paging The mapping relationship between the time domain offset of the frame and the grouping information. Alternatively, the mapping relationship between the time domain offset of the paging frame and the grouping information is predefined.

In some embodiments, if the number of time domain offsets of the paging frame is N, and a terminal device corresponding to a PO is divided into N groups, each terminal device group corresponds to a time domain offset of the paging frame The default time domain offset for the ungrouped terminal equipment corresponds to the paging frame. For example, the first time domain offset corresponds to the first terminal device grouping, the second time domain offset corresponds to the second terminal device grouping, and the Nth time domain offset corresponds to the Nth terminal device grouping. If a certain terminal device is not grouped, that is, the terminal device does not belong to any of the N terminal device groups, the terminal device corresponds to the default time domain offset; the default time domain offset may be the network The device configuration can also be pre-appointed; the default time domain offset can be any one of N time domain offsets, for example, the default time domain offset is N time domain offsets The first of them.

In other embodiments, if the number of time-domain offsets of the paging frame is N+1, and the terminal device corresponding to a PO is divided into N groups, the ungrouped terminal device corresponds to the first paging frame. A time domain offset; each terminal device group corresponds to a time domain offset other than the first time domain offset of the paging frame. For example, the first time domain offset corresponds to the ungrouped terminal device, the second time domain offset corresponds to the first terminal device grouping, and the N+1th time domain offset corresponds to the Nth terminal device Grouping.

Step S304: The terminal device determines a paging frame based on the time domain offset of the paging frame corresponding to the grouping information of the terminal device.

In specific implementation, the terminal device determines the terminal device group to which it belongs; and then according to the mapping relationship between the time domain offset of the paging frame and the grouping information, determines the time domain of the paging frame corresponding to the terminal device group described by itself Offset; finally the paging frame is determined according to the determined time domain offset.

In some embodiments, the mapping relationship between the time domain offset of the paging frame and the grouping information is shown in FIG. 4. Taking N=T/4 as an example, a PO includes 4 terminal equipment groups, and 4 terminal equipment The corresponding PF_offsets of the group are: 0, 1, 2 and 3; the terminal device group 1 uses the value of PF_offset to calculate the paging frame, and the terminal device group 2 uses the value of PF_offset to calculate the paging frame, and the terminal device The group 3 uses the value of PF_offset to calculate the paging frame, and the terminal device group 4 uses the value of PF_offset to calculate the paging frame. If the terminal device in the embodiment of the present application determines that it belongs to terminal device group 4, the terminal device uses the value of PF_offset to be 3 to calculate the paging frame.

Step S305: The terminal device performs paging message detection based on the determined paging frame.

In specific implementation, the terminal device detects the paging message by monitoring the PDCCH scrambled by the P-RNTI.

In the embodiment of the present application, the terminal device determines the paging frame for detecting the paging message according to the terminal device group to which it belongs. By limiting the paging frame for the terminal device to detect the paging message, it is possible to reduce unnecessary paging by the terminal device. The number of message detections reduces the probability of false alarms on paging and saves the power consumption of terminal equipment.

In the case that the paging parameter is the PDCCH monitoring opportunity for the terminal device to perform paging message detection, an optional processing procedure of the paging method provided in the embodiment of the present application, as shown in FIG. 5, includes:

Step S401: The terminal device determines the grouping information of the terminal device in a predefined manner or through the first configuration information sent by the network device.

Step S402: The terminal device receives the fourth configuration information sent by the network device.

In the embodiment of the present application, the fourth configuration information and the first configuration information may be the same configuration information, or may be different configuration information.

During specific implementation, the fourth configuration information includes at least one of the following:

1) A set of ControlResourceSet and Paging search space;

2) A first PDCCH-Monitoring OccasionOfPO sequence, the first PDCCH-Monitoring OccasionOfPO sequence is used to indicate the first PDCCH monitoring opportunity corresponding to each PO in a PF;

3) The number S of SSB sent by the network device at the time.

Step S403: The terminal device determines the number of PDCCH monitoring occasions for paging message detection.

In some embodiments, the terminal device determines the number of PDCCH monitoring occasions for paging message detection according to the fourth configuration information, which is equal to the number of groups N obtained by grouping the terminal devices corresponding to the paging occasion and is synchronized with the actual transmission by the network device The product of the number S of signal blocks. That is, the number of PDCCH monitoring occasions for the terminal device to detect the paging message is equal to N*S.

In other embodiments, the terminal device determines the number of PDCCH monitoring occasions for paging message detection according to the fourth configuration information, which is equal to the number of groups N obtained by grouping the terminal devices corresponding to the paging occasion plus 1, and then The product of the number S of synchronization signal blocks actually sent by the network device. That is, the number of PDCCH monitoring occasions for the terminal device to detect the paging message is equal to (N+1)*S.

Step S404: The terminal device determines the PDCCH on which the terminal device performs paging message detection based on the grouping information of the terminal device.

In some embodiments, if the number of PDCCH monitoring occasions for the terminal device to perform paging message detection is equal to N*S, each terminal device group corresponds to S consecutive PDCCH monitoring occasions. For example, the first terminal equipment group corresponds to the first group of S consecutive PDCCH monitoring opportunities in N*S PDCCH monitoring opportunities, and the second terminal equipment group corresponds to the second group of S consecutive PDCCH monitoring opportunities in N*S PDCCH monitoring opportunities. Monitoring timing, the Nth terminal equipment group corresponds to the Nth group of S consecutive PDCCH monitoring opportunities among the N*S PDCCH monitoring opportunities.

The terminal device determines the PDCCH monitoring time for itself to detect the paging message according to the grouping information of the terminal device where it is located. For example, if the terminal device belongs to the second terminal device group, the terminal device determines the PDCCH monitoring timing for detecting the paging message as: the second group of S consecutive PDCCH monitoring timings.

If the terminal device is not grouped, that is, the terminal device does not belong to any of the N terminal device groups, the terminal device determines that the PDCCH monitoring opportunity for detecting the paging message is: the first group of S consecutive PDCCH monitoring opportunities.

As shown in Figure 6, the terminal equipment corresponding to a paging occasion is divided into N=3 groups, the number of SSBs actually sent by the network equipment S=4 as an example, the terminal equipment within a paging occasion can carry out paging messages The number of detected PDCCH monitoring occasions is N*S=12, and the first PDCCH monitoring occasion corresponding to the paging occasion is determined according to the configuration parameter first PDCCH-Monitoring OccasionOfPO sequence. Then the first terminal equipment group corresponds to the first to fourth PDCCH monitoring occasions, that is, the terminal equipment in the first terminal equipment group detects the paging message at the first to fourth PDCCH monitoring occasions. The second terminal equipment group corresponds to the 5th to 8th PDCCH monitoring occasions, that is, the terminal equipment in the second terminal equipment group detects the paging message at the 5th to 8th PDCCH monitoring occasions. The third terminal equipment group corresponds to the 9th to 12th PDCCH monitoring occasions, that is, the terminal equipment in the third terminal equipment group detects the paging message at the 9th to 12th PDCCH monitoring occasions. Terminal devices that are not grouped detect the paging message at the first to fourth PDCCH monitoring occasions.

In other embodiments, if the number of PDCCH monitoring occasions for the terminal device to detect the paging message is equal to (N+1)*S, then each terminal device group corresponds to the first S consecutive excluding the paging occasions. S consecutive PDCCH monitoring opportunities other than the PDCCH monitoring timing. For example, the first terminal equipment group corresponds to (N+1)*S PDCCH monitoring opportunities in the second group of S consecutive PDCCH monitoring opportunities, and the second terminal equipment group corresponds to (N+1)*S PDCCH monitoring opportunities in the The third group of S continuous PDCCH monitoring opportunities, the Nth terminal equipment group corresponds to the N+1th group of S continuous PDCCH monitoring opportunities in the N*S PDCCH monitoring opportunities.

The terminal device determines the PDCCH monitoring time for itself to detect the paging message according to the grouping information of the terminal device where it is located. For example, if the terminal device belongs to the second terminal device group, the terminal device determines the PDCCH monitoring timing for detecting the paging message as: the third group of S consecutive PDCCH monitoring timings.
