Description

Measurement event configuration method and device

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

In a conventional long Term Evolution Carrier Aggregation (L ong Term Evolution Carrier Aggregation, L TECA) technology, a User Equipment (UE) may be served by multiple cells (cells) at the same time, only one of the cells carries a Physical Uplink Control CHannel (PUCCH), which is called a Primary Cell (PCell).

The UE can also report the cell with the best signal quality to the base station by monitoring the signal quality of each cell in real time, and the base station can inform the UE to use the cell with the best signal quality to carry the PUCCH, so that the throughput of the system can be improved.

As the number of serving cells of the UE increases, the PUCCH carried by the PCell is increasingly loaded, and in order to relieve the PUCCH load of the PCell, the BS may reselect one or more cells, which may be referred to as Secondary cells (scells), from other serving cells of the UE to carry the PUCCH. In this way, the UE may also use the PUCCH carried on the scells to feed back the reception of downlink data to the BS, thereby reducing the load of the PCell.

At present, a base station cannot update a cell with better signal quality to a current SCell, and a UE can only feed back a data receiving situation to the base station through the preselected SCell all the time, which is not beneficial to improving the system throughput.

Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

In the L TE CA technology, the PUCCH on the PCell of the UE is used for the UE to feed back downlink data reception conditions on all cells to the base station so as to help the base station to retransmit data which is not successfully received by the UE, therefore, the selection of a cell with a better measurement result as the PCell is important for the throughput performance of the system.

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

The method for configuring the measurement event enables the measurement event to be applicable 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 related measurement result reported by the UE.

Example 1:

an embodiment of the present invention provides a method and an apparatus for configuring a measurement event, where an execution subject is a base station, and as shown in fig. 1, the method includes the following steps:

101. generating a measurement configuration message; the measurement configuration message carries identification information of an SCell and identification information of a measurement event associated with the SCell, the SCell is a serving cell of the UE, and the SCell carries a PUCCH.

And the identification information of the SCell is the sequence number of the cell group to which the SCell belongs, or the sequence number of the SCell, or the symbol of the SCell. Of course, the base station is to determine the correspondence between the SCell and the measurement event in advance. For example, when the identification information of the SCell is Gi (i.e., the serial number of the cell group including the SCell), and the identification information of the measurement event is Ai, an association relationship between Gi and Ai may be established.

It should be noted that, before step 101, the base station groups serving cells of the UE, assigns a sequence number to the cells in each group, and only one SCell is in each cell group, where the identification information of the SCell may be Gi. If the base station allocates a sequence number for each SCell before step 101, the identification information of the SCell is the sequence number of the SCell. Alternatively, if the base station determines a symbol for the SCell unique to the UE before step 101, the identification information of the SCell is the symbol of the SCell.

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

Wherein the entry condition of the measurement event comprises: and the difference value obtained by subtracting the measuring result of the SCell from the measuring result of a neighbor cell of the SCell is larger than a first threshold value. Or the measurement result of a neighbor cell of the SCell is greater than a second threshold value, and the measurement result of the SCell is less than a third threshold value.

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

In a specific implementation, the UE determines one SCell in its own SCell according to an SCell identifier carried in a measurement configuration message sent by the base station, determines one measurement event according to an identifier of the measurement event associated with the SCell identifier carried in the measurement configuration message sent by the base station, determines an entry condition of the measurement event, and monitors a serving cell of the UE according to the measurement event. Further, the UE may report a neighbor cell that always satisfies the entry condition of the measurement event to the base station, and the base station may select to replace the current SCell with the neighbor cell.

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

dividing a service cell of the UE into N cell groups, and allocating a sequence number to each cell group, wherein only one SCell is in each cell group; and if so, the identification information of the SCell is the sequence number i of the cell group to which the SCell belongs.

The base station sends the corresponding relation between each serving cell and the sequence number of the cell group to which the serving cell belongs to the UE, so that the UE can determine an SCell according to the identification information of the SCell (the sequence number i of the cell group to which the SCell belongs) carried by the measurement configuration message sent by the base station. For example, if the identification information of the SCell is 2, the SCell determined by the UE after receiving the measurement configuration message is the only SCell in cell group 2.

Secondly, the base station allocates a sequence number for the SCell of the UE; and then, the identification information of the SCell is the sequence number j of the SCell. For example, if the identification information of the SCell is 2, the SCell determined by the UE after receiving the measurement configuration message is the SCell with sequence number 2.

And the base station sends the corresponding relation between each SCell and the sequence number of the SCell to the UE so that the UE can determine one SCell according to the identification information (the sequence number j of the SCell) of the SCell, which is carried by the measurement configuration message sent by the base station.

Thirdly, the base station determines a symbol for the SCell; then, the identification information of the SCell is a symbol of the SCell.

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

According to the configuration method of the measurement event provided by the invention, the base station generates the measurement configuration message carrying 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. And the UE determines the cell associated with the measurement event as the SCell according to the measurement configuration message, and determines the entry condition of the measurement event according to the SCell. Compared with the prior art, no scheme can configure the measurement event associated with the SCell for the UE, and the UE can only feed back the data receiving condition to the base station through the pre-selected SCell all the time, which is not beneficial to improving the system throughput. The method provided by the invention can configure the measurement event associated with the SCell for the UE so that the UE determines the neighbor cell with better signal quality than the pre-selected SCell and sends a report to the base station, and the base station can select and configure the UE to use the neighbor cell to replace the current SCell to carry the PUCCH, thereby being beneficial to improving the system throughput.

Example 2:

an embodiment of the present invention provides a measurement configuration method, where an execution subject is a UE, and as shown in fig. 2, the method includes the following steps:

201. receiving a measurement configuration message sent by a base station; the measurement configuration message carries identification information of a secondary cell (SCell) and identification information of a measurement event associated with the SCell, wherein the SCell is a serving cell of the UE and carries a PUCCH.

And the identification information of the SCell is the sequence number of the cell group to which the SCell belongs, or the sequence number of the SCell, or the symbol of the SCell. Of course, the base station is to determine the correspondence between the SCell and the measurement event in advance. For example, when the identification information of the SCell is Gi (serial number of the cell group including the SCell), and the identification information of the measurement event is Ai, an association relationship between Gi and Ai may be established.

202. And the UE determines the entry condition of the measurement event according to the identification information of the secondary cell (SCell) carried by the measurement configuration message and the identification information of the measurement event associated with the SCell.

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

In addition, the identification information of the SCell is different, which means that the base station has a different numbering method for the SCell. Correspondingly, the base station has a different numbering scheme for the SCell, and the UE receives different content transmitted by the base station. The following two cases are included:

when the identification information of the SCell is a sequence number i of a cell group to which the SCell belongs, the method further comprises the following steps: and the UE receives the corresponding relation between each service cell sent by the base station and the sequence number of the cell group to which the service cell belongs.

The UE determines an entry condition of the measurement event according to the identification information of the secondary cell SCell carried by the measurement configuration message and the identification information of the measurement event associated with the SCell, and specifically includes: and the UE determines the SCell in the cell group with the sequence number i as the cell associated with the measurement event. For example, the UE determines an SCell according to the identification information of the SCell (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 identification information of the SCell is 2, the SCell determined by the UE after receiving the measurement configuration message is the only SCell in cell group 2.

Secondly, when the identification information of the SCell is a sequence number j of the SCell, the method further comprises the following steps: and the UE receives the corresponding relation between each SCell sent by the base station and the sequence number of the SCell.

The UE determines an entry condition of the measurement event according to the identification information of the secondary cell SCell carried by the measurement configuration message and the identification information of the measurement event associated with the SCell, and specifically includes: and the UE determines the SCell with the sequence number j as a cell associated with the measurement event. For example, if the identification information of the SCell is 2, the SCell determined by the UE after receiving the measurement configuration message is the SCell with sequence number 2.

When the identification information of the SCell is a symbol of the SCell, the UE may determine the SCell according to the symbol of the SCell.

The UE determines an entry condition of the measurement event according to the identification information of the secondary cell SCell carried by the measurement configuration message and the identification information of the measurement event associated with the SCell, and specifically includes: and the UE determines the SCell as a cell associated with the measurement event. For example, if the symbol determined by the base station for the SCell unique to the UE is "PSCell", the identification information of the SCell carried by the measurement configuration message received by the UE is "PSCell", and the UE may determine an SCell according to the symbol "PSCell".

Of course, if the entry condition of the measurement event is always satisfied within the preset time, the UE reports the neighbor cell to the base station. So that the base station sends PUCCH configuration information to the UE, and the UE replaces the SCell with the neighbor cell to send PUCCH according to the SCell configuration information. In this way, the UE can always transmit the PUCCH using the cell with better signal quality, which is beneficial to improving the system throughput.

301. and the base station divides the service cell of the UE into N cell groups and allocates a sequence number to each cell group.

Only one SCell is in each cell group, so the identification information of the SCell may be the sequence number of the cell group to which the SCell belongs.

302. And the base station sends the corresponding relation between each service cell and the sequence number of the cell group to which the service cell belongs to the UE.

303. The base station associates an SCell with a measurement event.

Specifically, the identification information of the SCell may be associated with the identification information of the measurement event. Illustratively, the identification information Gi of the SCell (i.e., the sequence number of the cell group to which the SCell belongs) is associated with the identification information a1 of a measurement event.

304. The base station generates a measurement configuration message.

And a neighbor cell of the SCell is any serving cell of the UE.

309. And if the entry condition of the measurement event is always met within the preset time, the UE reports the neighbor cell to the base station.

310. The base station sends a PUCCH configuration message to the UE.

311. And the UE receives SCell configuration information sent by the base station.

312. And the UE replaces the SCell with the neighbor cell to transmit PUCCH according to the SCell configuration information.

Specifically, the UE may first deactivate cells in the cell group to which the SCell belongs, that is, stop uplink and downlink data transmission on these cells, and then release the existing PUCCH configuration of the SCell and use the PUCCH configuration carried in the PUCCH configuration message on the neighbor cell.

Example 4:

firstly, a base station 80 generates a measurement configuration message, wherein the measurement configuration message carries identification information of a secondary cell (SCell) and identification information of a measurement event associated with the SCell, the SCell is a serving cell of a User Equipment (UE), and the SCell carries an uplink physical control channel (PUCCH).

Secondly, the base station 80 sends the measurement configuration message to a UE90 (UE with the device 70 deployed), where the measurement configuration message is used for the UE to determine an entry condition of the measurement event according to the identification information of the SCell carried by the measurement configuration message and the identification information of the measurement event associated with the SCell.

And thirdly, the UE90 receives the measurement configuration message sent by the base station.

Fourthly, the UE90 determines the entry condition of the measurement event according to the identification information of the secondary cell (SCell) carried by the measurement configuration message and the identification information of the measurement event associated with the SCell.

And fifthly, the UE90 reports the identification information of a neighbor cell to the base station, and the neighbor cell always meets the entry condition of the measurement event within a preset time.

Sixthly, the base station 80 receives the identification information of a neighbor cell reported by the UE90, and sends a PUCCH configuration message to the UE.

And seventhly, the UE90 replaces the SCell with the neighbor cell to carry PUCCH according to the PUCCH configuration message.

In the communication system provided by the invention, the base station generates the measurement configuration message carrying 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. And the UE determines the cell associated with the measurement event as the SCell according to the measurement configuration message, and determines the entry condition of the measurement event according to the SCell. Compared with the prior art, no scheme can configure a measurement event for the SCell, and the UE can only feed back the data receiving condition to the base station through the preselected SCell all the time, which is not beneficial to improving the system throughput. The method provided by the invention can configure the measurement event for the SCell so that the UE can determine the neighbor cell with better signal quality than the preselected SCell and send a report to the base station, and the base station can select and configure the UE to replace the current SCell to carry the PUCCH, thereby being beneficial to improving the system throughput.
