Description

Method and device for secondary carrier configuration

technical field

The present invention relates to the field of wireless communication, in particular to a method and device for configuring auxiliary carriers.

Background technique

3GPP (The3rdGenerationPartnershipProject, Third Generation Partnership Project) LTE-A (Long-TermEvolution-Advanced, Advanced Long-Term Evolution) proposed CA (CarrierAggregation, carrier aggregation) technology, which is about to aggregate multiple carriers scattered in multiple frequency bands together to form Greater bandwidth to improve UE (UserEquipment, user equipment) greater peak throughput. The aggregated carrier is composed of one PCC (PrimaryCompositionCarrier, primary carrier) and one or more SCCs (SecondaryCompositionCarrier, secondary carrier). Wherein, the PCC corresponds to a PCell (Primary serving cell, primary serving cell), and the SCC corresponds to an SCell (Secondary serving cell, secondary cell). The UE accesses the network through the PCell that transmits RRC (Radio Resource Control, radio resource control) signaling. Since there is no RRC connection between the UE and the SCell, all information about the SCell is sent to the UE through the PCell. After the UE accesses the PCell, the PCell needs to configure and activate the SCC for the UE, and then the UE can use the SCC for data transmission.

In the prior art, the commonly used SCell configuration method uses a blind configuration method, wherein the eNB first notifies the UE of the SCell information through the RRCConnectionRecofiguraition message, the UE saves the SCell information, and feeds back RRCConnectionRecofiguraitionComplete to the eNB, and then the eNB sends a MAC CE to the UE to activate the SCC , the UE can simultaneously use the SCC and the PCC to transmit data.

In the prior art, in the carrier aggregation network, if it is determined to use the blind configuration method to configure the auxiliary carrier, the blind configuration can only be used in this cell. If the UE initially accesses or switches to the coverage of the target PCC, the configuration fails. SCC, for example (the signal quality of the UE on the PCC is very good, but the signal on the SCC is weak or the SCC cannot be detected at all, resulting in the failure of the SCC to complete the configuration normally). However, in the actual process, regardless of whether the UE is successfully configured with the SCC The RRCConnectionRecofiguraitionComplete message will be fed back to the eNB, and the eNB that receives the RRCConnectionRecofiguraitionComplete message will mistakenly think that the UE has successfully configured the SCC. Therefore, when data transmission is required, the eNB will activate the SCell through the MACCE message and perform data transmission on the SCell (the UE will not feed back any information to the eNB if it cannot receive data from the SCell. Configure SCC). This means that if the UE has data transmission before entering the RRC_IDLE state, it can only transmit data on the PCC but not on the SCC, and the rate cannot be increased.

An embodiment of the present invention provides a secondary carrier configuration method, as shown in FIG. 1 , including:

S101. Send configuration information of a first secondary carrier to a user equipment, so that the user equipment configures the first secondary carrier;

S103. If the indication information of the first secondary carrier measurement result sent by the user equipment is received, perform S101.

An embodiment of the present invention provides a secondary carrier configuration method, in which a base station sends configuration information of a first secondary carrier to a user equipment, so that the user equipment configures the first secondary carrier; if it is determined that the user equipment configures the If the first secondary carrier fails, send measurement indication information for the first secondary carrier to the user equipment; if receiving the indication information of the first secondary carrier measurement result sent by the user equipment, send the The user equipment sends the configuration information of the first secondary carrier, so that the user equipment configures the first secondary carrier. This method can make the user equipment fail to configure successfully when the signal quality of the secondary carrier is poor. When configuring the secondary carrier, measure the signal quality of the first secondary carrier from poor to good by sending measurement indication information for the first secondary carrier to the user equipment, and after the signal quality of the first secondary carrier becomes good By sending the configuration information of the first secondary carrier to the user equipment and reconfiguring the first secondary carrier, the method can make full use of the first secondary carrier to increase the rate of the user equipment, and avoid When , the base station mistakenly thinks that the user equipment has successfully configured the first secondary carrier, and transmits data on the first secondary carrier, resulting in waste of resources.

It should be noted that the execution subject of the embodiment of the present invention is the base station. The base station may be an evolved base station (NodeB or base station or e-NodeB, evolutionalNodeB) in LTE, which is not limited in this embodiment of the present invention.

Wherein, the user equipment (User Equipment, UE) in the embodiment of the present invention may be a user equipment that newly accesses a cell within the coverage of the base station, or may be handed over from a cell within the coverage of the first base station to within the coverage of the base station. The user equipment of the cell is not limited in this embodiment of the present invention.

Wherein, the first secondary carrier refers to any secondary carrier in the cell within the coverage of the base station. Since the method and principle of configuring any secondary carrier in the cell within the coverage of the base station by the user equipment are the same as the first secondary carrier, the embodiments of the present invention Only the first secondary carrier is used as an example for description, and has no special indication meaning.

Wherein, the configuration information of the first secondary carrier refers to iconic information that can uniquely identify the first secondary carrier, and any identifying information that can uniquely identify the secondary carrier can be used to identify the first secondary carrier. The configuration information of the first secondary carrier includes but not limited to: the absolute frequency point information of the first secondary carrier and/or the physical carrier number of the first secondary carrier and/or the secondary cell number corresponding to the first secondary carrier and/or the type of the first secondary carrier.

The configuration information of the first secondary carrier may be sent by the base station to the user equipment through point-to-multipoint system broadcast information or an RRC connection reconfiguration (ConnectionRecofiguraition) message, or the base station may send the configuration information of the first secondary carrier through point-to-multipoint A point-to-point RRC connection reconfiguration message or a dedicated control channel is sent to the user equipment. Preferably, as shown in FIG. 2 , the user equipment in this embodiment of the present invention may receive the first secondary Carrier configuration information.

For S101, after the user equipment newly accesses a cell within the coverage of the base station or switches from a cell within the coverage of the first base station to a cell within the coverage of the base station, the base station directly sends the first secondary Carrier configuration information, so that the user equipment configures the first secondary carrier, and may also be used when the user equipment newly accesses a cell within the coverage of the base station or is handed over from a cell within the coverage of the first base station to the secondary carrier. After the cell within the coverage of the base station, the request information sent by the user equipment is received, and after the base station receives the request message, it sends a first feedback message to the user equipment, and the first feedback message is used to include the Configuration information of the first secondary carrier, so that the user equipment configures the first secondary carrier; in these two modes, the base station may receive the confirmation sent by the user equipment after receiving the configuration information of the first secondary carrier information, judging whether the user equipment has successfully received the configuration information of the first secondary carrier, and the content of the confirmation information includes but not limited to: message type, transmission identifier, and encoding items. If the confirmation information indicates that the user equipment has not received the configuration information of the first secondary carrier, the base station may resend the configuration information of the first secondary carrier to the user equipment.

Wherein, the measurement indication information may include A3 measurement event, A4 measurement event, A5 measurement event, etc. Preferably, the embodiment of the present invention selects the A4 measurement event.

The measurement indication information may be sent by the base station to the user equipment through point-to-multipoint system broadcast information or an RRC connection reconfiguration (ConnectionReconfiguraition) message, or the base station sends the measurement indication information through a point-to-point RRC connection reconfiguration message Or a dedicated control channel is sent to the user equipment. Preferably, as shown in FIG. 2, the user equipment in this embodiment of the present invention may receive the measurement indication information sent by the base station through an RRC connection reconfiguration message, and the measurement indication information includes A4 Measure events.

After receiving the measurement instruction information for the secondary carrier sent by the base station, the user equipment may send a confirmation message to the base station through an RRC Connection Reconfiguration Complete (RRCConnectionRecofiguraitionComplete) message, and the confirmation message is used to indicate that the user equipment has received the secondary carrier. The above-mentioned secondary carrier measurement indication information, specifically, the content of the confirmation information includes but not limited to: message type, transmission identifier, and encoding items.

A possible implementation manner, for example, as shown in FIG. 3, the specific steps of S102 may include:

S1021A. Send data to the user equipment through the first secondary carrier;

S1022A. If the base station does not receive the feedback message from the user equipment on the first secondary carrier within a preset time, determine that the user equipment fails to configure the first secondary carrier.

Among them, the embodiment of the present invention does not limit the specific value of the preset time, which can be determined according to the actual situation. If the base station does not receive the feedback message sent by the user equipment to the base station when the preset time arrives, determine that the user equipment If the configuration of the first secondary carrier fails, send measurement indication information for the first secondary carrier to the user equipment; if the base station receives the feedback message sent by the user equipment before the preset time arrives, then determine If the configuration of the first secondary carrier is successful, the base station may activate the secondary carrier by sending an activation instruction to the user equipment.

The form of the feedback message is not limited in the present invention, for example, ACK/NACK response information or CQI (ChannelQuality Indicator, channel quality indicator) information may be used. Usually, a high value of CQI indicates that a channel has good quality, and vice versa. If the user equipment successfully receives and demodulates the data sent by the base station, it will feed back an ACK response message to the base station through uplink control signaling; if the user equipment fails to successfully receive and demodulate the data sent by the base station, otherwise it will feed back a NACK message. After receiving the NACK message, the base station confirms that the first secondary carrier has a problem and needs to be reconfigured.

Another possible implementation manner, for example, as shown in FIG. 4, the specific steps of S102 may include:

S1021B. Receive the first secondary carrier configuration result indication information sent by the user equipment, where the indication information is used to indicate that the user equipment configures the secondary carrier successfully or the user equipment fails to configure the secondary carrier ;

S1022B. If the indication information indicates that the user equipment fails to configure the secondary carrier, determine that the user equipment fails to configure the first secondary carrier.

Wherein, the embodiment of the present invention does not limit the specific form and transmission method of the indication information, as long as it can be used to feed back to the base station whether the user equipment has successfully configured the secondary carrier. The configuration complete (RRCConnectionReconfigurationComplete) message receives the indication information sent by the user equipment. In the specific implementation process, a field for identifying the success or failure of the user equipment to configure the first secondary carrier may be added to the RRC connection reconfiguration complete message, for example , SCellConfigInfo=1 or SCellConfigInfo=0 field.

If the base station parses and finds that the RRC connection reconfiguration complete message contains the SCellConfigInfo=1 field, it means that the user equipment configures the first secondary carrier successfully, and the base station can send an activation instruction (for example, MAC: SCellActivation) to the user equipment field) is used to activate the first secondary carrier, and then send data to the user equipment on the first secondary carrier.

If the base station resolves that the RRC connection reconfiguration complete message contains SCellConfigInfo=0, it means that the user equipment fails to configure the secondary carrier, and at this time, the base station can stop sending data to the user equipment on the first secondary carrier , may also send the measurement indication information of the first secondary carrier to the user equipment until the base station obtains the measurement result of the first secondary carrier whose signal quality meets the requirements, and then renew the measurement result for the user equipment The first secondary carrier is configured, thereby avoiding wrong allocation and waste of resources.

In the specific implementation process, the user equipment may set a time parameter for reconfiguring the first secondary carrier configuration information in the indication information of the first secondary carrier measurement result. If the time parameter is zero, it means that the user equipment is in The base station can configure the first secondary carrier immediately after resending the first secondary carrier configuration information. If the time parameter is not zero, it means that the user equipment can reconfigure the first secondary carrier configuration sent by the base station after the time parameter arrives. information; if the user equipment does not set the time parameter for reconfiguring the first secondary carrier configuration information in the indication information of the first secondary carrier measurement result, it can be considered that the user equipment resends the first secondary carrier configuration information at the base station The first secondary carrier may be configured immediately after the information.

Optionally, when the indication information indicates that the user equipment configures the secondary carrier successfully, the method further includes:

The base station sends an activation instruction to the user equipment to activate the secondary carrier.

The activation instruction refers to activation information of the corresponding secondary carrier when the user equipment successfully configures the secondary carrier.

In the specific implementation process, the base station can set an activation time parameter in the above message. If the value of this parameter is zero, it means that the secondary carrier configured successfully by the user equipment will be activated immediately after the base station receives the message that the secondary carrier configuration is successful. Carrier, the parameter is not zero, then activate the successfully configured secondary carrier when the activation time arrives; if the base station does not set the activation time parameter, the user equipment can consider that the secondary carrier is activated immediately after the base station receives the message that the secondary carrier configuration is successful The secondary carrier successfully configured by the user equipment.

Specifically, for the specific form and specific content of sending the first secondary carrier configuration result indication information to the base station, reference may be made to the description in Embodiment 1, which will not be repeated in this embodiment of the present invention.

Wherein, before the sending the indication information of the first secondary carrier configuration result to the base station, the method further includes:

S206. The user equipment judges whether the secondary carrier can be configured;

Exemplarily, a possible implementation manner for the user equipment to determine whether the first secondary carrier can be configured includes:

S2061A. The user equipment determines whether the secondary carrier information can be detected according to the first secondary carrier configuration information;

S2062A. If the user equipment can detect the first secondary carrier, the user equipment can successfully configure the first secondary carrier; if the user equipment cannot detect the first secondary carrier, then the The user equipment fails to configure the first secondary carrier.

Since each user equipment has the ability to detect the secondary carrier according to its own hardware status information and automatically configure the secondary carrier according to the secondary carrier information, if the user equipment cannot detect the secondary carrier according to the secondary carrier information after accessing the network A secondary carrier, that is, the user equipment cannot establish a connection with the secondary carrier, and the user equipment fails to configure the secondary carrier. If the user equipment can establish a connection with the secondary carrier according to the secondary carrier information after accessing the network , the user equipment configures the secondary carrier successfully.

This embodiment of the present invention does not limit the preset strength. When the configuration strength requirement of the carrier is relatively high, the specific value of the preset strength can be set relatively high; if the configuration strength requirement of the user equipment for the first secondary carrier is relatively low, the preset value can be set to The specific numerical value of the intensity is set relatively low.

S2062B. If the signal strength of the secondary carrier detected by the user equipment is greater than the preset strength, the user equipment can successfully configure the secondary carrier. If the signal strength of the secondary carrier detected by the user equipment is less than the preset strength, the user equipment fails to configure the secondary carrier.
