Description

Mainly includes item tracking/tracking, environment/climate monitoring, remote medical care, etc. Due to the wide range of applications of MTC, the number of research topics related to MTC is also increasing. Research is being conducted to see if it is possible and how to improve network coverage. However, one of the key assumptions regarding these studies is that enhancements based on the conventional LTE system,
It is to realize the research goals of these subjects.

As the research on these issues continues to progress, both of these issues come to face the same problem: how to obtain the system information (SI) broadcast by the network. or The system information is essential information for the normal working of the User Equipment (UE, User Equipment) (regardless of whether it is in an idle state or a connected state). System information is broadcast by a base station in a specific cell, and all UEs in this cell need to obtain this system information. The UE can perform processes such as cell selection/reselection, cell handover, service initiation, etc. only after obtaining these system information.

In the embodiment of the present invention, MTC UE will be described as an example below. It should be noted that the system information acquisition method and the change period configuration method in the embodiments of the present invention are not limited to MTC UE, and can be applied to the embodiments of the present invention as long as there are at least two types of user equipment. .

System information can be broadcast by the base station in a particular cell to achieve control of idle and connected user equipments. As time changes, the network can update system information based on current network conditions. In the conventional LTE system, by adopting the modification period (MP, Modification Period),
Updating of system information can be realized.

FIG. 1 is a diagram showing updating of system information in the conventional standard. As can be seen from Figure 1, if there is any change in system information (other than ETWS (Earthquake and Tsunami Warning System), CMAS (Commercial Mobile Alert Service), and EAB (Extended Access Barring) parameters), the network side An update instruction (for example, by paging information) is transmitted within cycle n, and updated system information is transmitted within change cycle n+1.

If the UE receives an update indication from the network side, the update indication (eg, change period n)
It is necessary to obtain new system information as soon as the next one modification period of (eg, modification period n+1) starts. The modification period T _MP is determined by two parameters, which are the default paging cycle T _paging and the modification period coefficient MP _coe , respectively, and these two parameters are reported by the base station. .

T _MP =MP _coe *T _paging (1)
As shown in the above formula (1), the change cycle value can be obtained from the paging cycle value and the change cycle coefficient value. Also, the boundary of the modification period is represented by a System Frame Number (SFN) value that satisfies a certain condition, that is, SFN mod m=0. Of these, m is the number of radio frames included in _TMP .

An embodiment of the present invention provides a method for obtaining system information, and the embodiments of the present invention are described below from the base station side. FIG. 2 is a flow chart of a system information acquisition method according to an embodiment of the present invention, as shown in FIG. 2, the acquisition method includes the following steps.

Step 201: the base station sets at least two indicators for system information update indications, the at least two indicators respectively corresponding to at least two user equipments;
Step 202: The base station sends an indicator to the user equipment, and the user equipment obtains system information based on its own modification period.

In this embodiment, the base station side can set indicators for instructing system information update for each of at least two UEs in the same cell. For convenience, the conventional UE and the MTC UE will be described below as examples, but the present invention is not limited thereto. For example, there may be other types of UEs, or there may be more than three types of UEs, and more than three types of indicators can be used to indicate these UEs, and the actual situation A specific implementation method can also be determined according to the requirements.

In this embodiment, each of the at least two indicators may be included in the paging information. The base station independently configures at least two system information update indicators to achieve the purpose of notifying at least two UEs (conventional UE and MTC UE) respectively. Among them, at least two UEs can be configured with different modification periods, for example, different modification periods can be set in advance for at least two UEs, and the modification periods are configured by the base station. and the invention is not limited to this.

For example, a legacy UE and an MTC UE can be configured with different modification periods, respectively, that is, a modification period PA can be configured for a legacy UE, and a modification period PB can be configured for an MTC UE. be able to. Among them, PA may be smaller than PB.

In this embodiment, after receiving the indicator sent by the base station, each user equipment can update the system information according to its own modification period.

FIG. 3 is a diagram showing an example of a system information acquisition method according to an embodiment of the present invention. As shown in FIG. 3, the change period of the conventional UE (UE A) is PA, and the change period of the MTC UE (UE B) is PB. UE
After A receives the indicator in the change period n, if the indicator is for the UE A, the UE A updates the system information in the change period n+1. As shown in FIG. 3, UE B receives an indicator at a change period m, and if the indicator is an indicator for UE B, UE B
updates system information at change cycle m+1.

As can be seen from the above embodiments, the base station independently sets indicators for updating system information, respectively, so that the MTC UE can not only obtain the latest system information in a timely manner, but also It is also possible to reduce the power consumption of the MT UE without acquiring unnecessary system information.

FIG. 4 is a diagram showing another method of obtaining system information according to an embodiment of the present invention. As shown in FIG. 4, the acquisition method includes the following steps.

Step 401: The base station configures modification periods for at least two user equipments respectively;
Step 402: the base station sets indicators for indicating at least two system information updates, the at least two indicators corresponding to at least two user equipments;
Step 403: The base station sends an indicator to the user equipment, which causes the user equipment to:
Get system information based on your change cycle.

In this embodiment, the new modification period value may be determined by the base station, transmitted by broadcasting in system information; or transmitted by transmitting the relevant parameters in dedicated signaling. Also good, e.g. RRC (Radio Resource Control)
It can be transmitted by signaling or MAC (Medium Access Control) signaling.

In step 401, one of them (conventional UE) may adopt the conventional standard modification cycle value; the other user equipment (MTC UE) may perform the following processing.

In one implementation, a modification period value may be sent to the user equipment. For example, the base station may directly generate one new modification period value and then send the modification period value to the user equipment.

Alternatively, in another implementation, by sending the paging periodicity value to the user equipment, the user equipment can obtain the modification periodicity value based on the paging periodicity value and the existing modification periodicity factor. For example, if the base station generates only one new default paging period T ^* _paging and reuses the existing modification period factor, the corresponding modification period value T ^* _MP is T ^* _MP =MP _coe * It can be expressed as T ^* _paging .

Alternatively, in another implementation, a paging periodicity value and a modification periodicity factor may be sent to the user equipment so that the user equipment obtains a modification periodicity value based on the paging periodicity value and the modification periodicity factor. For example, if the base station generates one new default paging period T ^* _paging and one new change period factor MP ^* _coe , the corresponding change period value T ^* _MP is T ^* _MP =MP ^* _coe *T ^* _paging can be expressed as

Also, the boundaries of the new modification period may be determined in a conventional manner, ie SFN mod m ^* =0, where m ^* is the number of radio frames contained in T ^* _MP .

After configuring the change periods for the at least two user devices respectively in step 401, steps 402 and 403 may be performed to obtain system information, the specific contents of which are the steps 201 and 403 described above. 202 can be referred to.

In this embodiment, the system information may be updated partially or entirely. Some system information may be updated independently for different UEs in the same cell and may need to be updated synchronously.

In one implementation, transmitting the indicator to the user equipment in step 403 specifically transmits the indicator at different times for the two or more user equipment, thereby allowing the two or more user equipment may involve simultaneously updating some or all of the system information based on their respective change periods.

First, a simple classification may be made for system information, e.g., legacy UE and MTC UE
System information that requires simultaneous updating is called A-type system information, for example, TDD (Time Division Duplex) configuration in Master Information Block (MIB, Master Information Block), System Information Block 1 (SIB1, System Information Block 1) and Bandwidth indicator, frequency information in System Information Block 2 (SIB2), etc. Other system information that is not included in the A-type system information may be referred to as B-type system information.

Based on this, the new system information update mechanism defines two system information change indicators, one used for legacy UEs and one used for new UEs. can be If there is a change in the class B system information, the base station can independently set two system information update indicators to achieve the purpose of notifying the old UE and the new UE respectively. If there is a change in the class A system information, the base station should ensure that the old UE and the new UE update the system information at the same time.

FIG. 5 is a diagram showing another example of the system information acquisition method according to the embodiment of the present invention. As shown in FIG. 5, the change period of the conventional UE (UE A) is PA, and the change period of the MTC UE (UE B) is PB.
In order to allow the conventional UE and the MTC UE to acquire class A information synchronously, the indicator for UE A is transmitted at the modification period n+8, and the indicator for UE B is transmitted at the modification period m+1. Thus, UE A and UE B can update the system information at the same time (at the start of change cycle n+9 and change cycle m+2).

In this embodiment, the method further comprises transmitting some or all of the system information to the user equipment via dedicated signaling.

For example, after the introduction of a new modification period, a UE using the new modification period may affect the communication of other UEs in the current network because it does not have new system information when it tries to start uplink service. There is Thus, some system information can be sent to the UE in the form of dedicated signaling, eg it may be carried in the RRC signaling of SRB1 (Signaling Radio Bearer) and SRB2.

Note that the method of transmitting part or all of the system information to the user equipment through dedicated signaling is not limited to using at least two indicators or to using at least two modification periods. It can be applied even when using one indicator or one modification period.

As can be seen from the above embodiments, the base station independently configures indicators for updating system information for the user equipment, respectively, so that, for example, the MTC UE acquires the latest system information in a timely manner. In addition, the power consumption of the MTC UE can be reduced without unnecessary system information acquisition.
