Description

Configuration method and device for measuring event

Technical field

The present invention relates to the field of communications, and in particular, to a method and an apparatus for configuring a measurement event.

Background technique

In the traditional Long Term Evolution Carrier Aggregation (LTE) technology, a user equipment (User Equipment, UE) can be served by multiple cells at the same time, and only one cell in these cells carries physical uplink control. Channel (Physical Uplink Control CHannel, PUCCH), this cell is called Primary Cell (PCell). Each UE feeds back the downlink data reception status to the base station (BS) through the PUCCH on the PCell, so that the BS retransmits the data that the UE receives the failure.

The UE can also report the signal quality of each cell in real time, and report the cell with the best signal quality to the base station. The base station can notify the UE to use the cell with the best signal quality to carry the PUCCH, which can improve the throughput of the system.

As the number of serving cells of the UE increases, the load of the PUCCH carried by the PCell may become heavier and heavier. To alleviate the PUCCH load of the PCell, the BS may select one or more cells from other serving cells of the UE to carry the PUCCH. A cell may be referred to as a secondary cell (SCell). In this way, the UE can also use the PUCCH carried on the SCells to feed back the downlink data to the BS, thereby reducing the load on the PCell.

At present, the base station cannot update the cell with better signal quality to the current SCell, and the UE can only feedback the data reception status to the base station through the pre-selected SCell, which is not conducive to the improvement of the system throughput.

detailed description

The technical solutions in the embodiments of the present invention are clearly and completely described in the following with reference to the accompanying drawings in the embodiments of the present invention. It is obvious that the described embodiments are only a part of the embodiments of the present invention, but not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative efforts are within the scope of the present invention.

In the LTE CA technology, the PUCCH on the PCell of the UE is used by the UE to feed back the downlink data reception status on all the cells to the base station, so as to help the base station resend the data that is not successfully received by the UE, so that a measurement result is better. Community It is important for PCell to measure the throughput performance of the system. The base station can configure a measurement event for the UE, so that a better cell can be selected as a PCell among the multiple neighbor cells.

Similar to PCell, choosing a cell with better measurement results as SCell is also important for the throughput performance of the system. However, the current entry condition of the measurement event is set for the PCell, which makes the measurement event only applicable to the PCell, and is not applicable to the SCell, so that the base station cannot select a cell with better measurement result as the SCell using the measurement event.

The configuration method of the measurement event provided by the present invention is such that the measurement event can also be applied to the SCell, so that the base station can configure the UE to monitor the measurement event on the SCell, and select a better cell as the SCell according to the relevant measurement result reported by the UE.

Example 1:

The embodiment of the invention provides a method and a device for configuring a measurement event. The execution entity is a base station. As shown in FIG. 1 , the method includes the following steps:

The measurement configuration message carries the identification information of the SCell and the identification information of the measurement event associated with the SCell, where the SCell is a serving cell of the UE, and the SCell carries a PUCCH.

The identifier information of the SCell is a sequence number of the cell group to which the SCell belongs, or a sequence number of the SCell, or a symbol of the SCell. Of course, the base station needs to predetermine the correspondence between the SCell and the measurement event. For example, when the identifier information of the SCell is Gi (ie, the sequence number of the cell group including the SCell), and the identifier information of the measurement event is Ai, the association relationship between Gi and Ai can be established.

It should be noted that, before step 101, the base station groups the serving cells of the UE, and assigns a sequence number to the cells in each group, and there is only one SCell in each cell group, and the identifier information of the SCell can be It is the above Gi. If the base station assigns a sequence number to each SCell before step 101, the identifier information of the SCell is the sequence number of the SCell. Or, if the base station is a unique SCell of the UE determines a symbol before step 101, the identifier information of the SCell is a symbol of the SCell.

102. The base station sends the measurement configuration message to the UE, where the measurement is configured. The message is used by the UE to determine an entry condition of the measurement event according to the identifier information of the SCell carried by the measurement configuration message and the identifier information of the measurement event associated with the SCell.

The entry condition of the measurement event includes: a measurement result of a neighbor cell of the SCell minus a measurement result of the SCell is greater than a first threshold. Or the measurement result of a neighbor cell of the SCell is greater than a second threshold, and the measurement result of the SCell is smaller than a third threshold.

It should be noted that the measurement result may be a signal quality value. The second threshold value may be greater than or equal to the third threshold value. The first threshold value, the second threshold value, and the third threshold value may all be empirical values, which are not limited herein.

In a specific implementation, the determining, by the UE, the SCell identifier carried in the measurement configuration message sent by the base station in the SCell of the base station, and determining the identifier of the measurement event associated with the SCell identifier carried in the measurement configuration message sent by the base station A measurement event determines an entry condition of the measurement event and monitors the serving cell of the UE according to the measurement event. Further, the UE may also report a neighboring cell that always meets the entry condition of the measurement event to the base station, and the base station may choose to replace the current SCell with the neighboring cell.

Further, in a preferred embodiment of the present invention, before the generating the measurement configuration message, the method further includes the following three situations:

1. The serving cell of the UE is divided into N cell groups, and each cell group is assigned a sequence number, and each cell group has only one SCell; then, the SCell identification information is the cell group to which the SCell belongs. Serial number i.

Sending, by the base station, the correspondence between the serving cell and the sequence number of the cell group to which the serving cell belongs, to the UE, so that the identifier of the SCell carried by the UE according to the measurement configuration message sent by the base station The sequence number of the cell group i) determines an SCell. For example, if the identifier information of the SCell is 2, the SCell determined by the UE after receiving the measurement configuration message is the only SCell in the cell group 2.

The base station allocates a sequence number to the SCell of the UE; the identifier information of the SCell is the sequence number j of the SCell. For example, if SCell's identification letter The information is 2, then the SCell determined by the UE after receiving the measurement configuration message is the SCell with the sequence number 2.

The base station sends a correspondence between the SCell and the sequence number of the SCell to the UE, so that the UE determines one according to the identifier information of the SCell (the sequence number of the SCell) carried by the measurement configuration message sent by the base station. SCell.

The base station determines a symbol for the SCell; then, the identifier information of the SCell is a symbol of the SCell.

Transmitting a correspondence between the SCell and a symbol of the SCell to the UE. For example, if the symbol determined by the base station for the unique SCell of the UE is “PSCell”, the identifier information of the SCell carried by the measurement configuration message received by the UE is “PSCell”, and the UE may determine one SCell according to the symbol “PSCell”.

The method for configuring a measurement event provided by the present invention, the base station generates a measurement configuration message that carries the identification information of the SCell and the identification information of the measurement event associated with the SCell, and sends the measurement configuration message to the UE. Determining, by the UE, the cell associated with the measurement event as the SCell according to the measurement configuration message, and determining an entry condition of the measurement event according to the SCell. Compared with the prior art, there is no solution for the UE to configure the measurement event associated with the SCell. The UE can only feed back the data reception status to the base station through the pre-selected SCell, which is not conducive to the improvement of the system throughput. The method provided by the present invention is capable of configuring a measurement event associated with the SCell for the UE, so that the UE determines a neighbor cell with a better signal quality than the pre-selected SCell, and sends a report to the base station, and the base station may choose to configure the UE to replace the current cell with the neighbor cell. The SCell carries the PUCCH, which is beneficial to the improvement of system throughput.

Example 2:

An embodiment of the present invention provides a measurement configuration method, where the execution entity is a UE. As shown in FIG. 2, the method includes the following steps:

201. Receive a measurement configuration message sent by a base station, where the measurement configuration message carries identifier information of a secondary cell SCell and identifier information of a measurement event associated with the SCell, where the SCell is a serving cell of the UE, and the SCell is Carry PUCCH.

The identifier information of the SCell is a sequence number of the cell group to which the SCell belongs. Or the serial number of the SCell, or the symbol of the SCell. Of course, the base station needs to predetermine the correspondence between the SCell and the measurement event. For example, when the identifier information of the SCell is Gi (the sequence number of the cell group including the SCell), and the identifier information of the measurement event is Ai, the association relationship between Gi and Ai can be established.

202. The UE determines an entry condition of the measurement event according to the identifier information of the secondary cell SCell and the identifier information of the measurement event that is associated with the SCell.

It should be noted that the measurement result may be a signal quality value. The second threshold value may be greater than or equal to the third threshold value.

In addition, the identification information of the SCell is different, which means that the base station has different numbering methods for the SCell. Correspondingly, the base station has different numbering methods for the SCell, and the content received by the UE and transmitted by the base station is different. Including the following two situations:

When the identifier information of the SCell is the sequence number i of the cell group to which the SCell belongs, the method further includes: the UE receiving, between the serving cell and the sequence number of the cell group to which the serving cell belongs, Correspondence relationship.

Determining, by the UE, the entry condition of the measurement event according to the identifier information of the secondary cell SCell and the identifier information of the measurement event that is associated with the SCell, where the UE includes the cell group with the sequence number i The SCell in the determination is a cell associated with the measurement event. For example, the UE determines an SCell according to the identifier information of the SCell (the sequence number i of the cell group to which the SCell belongs) carried in the measurement configuration message sent by the base station. For example, if the identifier information of the SCell is 2, the SCell determined by the UE after receiving the measurement configuration message is the only SCell in the cell group 2.

When the identifier information of the SCell is the sequence number of the SCell, the method further includes: receiving, by the UE, a correspondence between each SCell sent by the base station and a sequence number of the SCell.
