Along with the development of mobile communication technology, transmission rate and service quality that system can provide are more and more higher, and customer service has also proposed more and more higher requirement to transmission rate.At present, 3GPP (The 3rd Generation Partnership Project, third generation partner program) introduce CA (Carrier Aggregation, carrier aggregation) technology, in order to realize in guaranteeing general user's transmission rate, also for a part of user provides higher throughput, avoid increasing considerably configured bandwidth simultaneously.

Utilize carrier convergence technology, UE (User Equipment, subscriber equipment) can use multiple CC (Component Carrier, member carrier) to carry out uplink and downlink communication simultaneously, thereby supports high speed data transfer.In the time that user rate reduces, can release portion member carrier, only retain a resident carrier wave.System can, by the partial carrier wave Resource Supply discharging to other users' uses, be transmitted object thereby reached flexibly, dynamically.

Carrier aggregation can be divided into intra-band CA (intra-band Carrier Aggregation, converges in band) and inter-band CA (inter-band Carrier Aggregation, interband converges).For intra-band CA, polymerization be the carrier wave of same frequency range, therefore the carrier wave coverage in intra-band CA can be consistent.For inter-band CA, polymerization be the carrier wave of different frequency range.Because the carrier wave coverage of low-frequency range is larger, the carrier wave coverage of high band is less, so carrier wave coverage is inconsistent in inter-band CA.

If adopt inter-band CA carrier polymerizing method, for high band carrier wave, the carrier wave of for example 3.5GHz or 6GHz, can distribute larger bandwidth for transfer of data, but its coverage is less, in the process moving at UE, UE need to switch or cell reselection frequently, thereby increased the power consumption of UE, and lower user's experience.For fear of the frequent switching of UE, can adopt in the prior art heterogeneous network to serve UE, jointly serve UE by macro base station and little base station.Macro base station extensively covers, and is responsible for the transmission of the transmission of UE control signal and the data of some low data rates.The enhancing of data surface service is only done in little base station, mainly carries out the transmission of high-speed data, and does not carry out the transmission of control signal.Under this kind of scene, UE need to monitor the schedule information of macro base station, but this monitoring also can consume certain power consumption.

The embodiment of the present invention provides a kind of control UE (User Equipment, subscriber equipment) method of monitoring carrier wave, as shown in Figure 1, comprising:

101, the first base station sends the first Indication message to described UE, monitor DSS (the UE-specific Search Space of the first carrier of described the first base station to indicate described UE to stop, dedicated search space) all or part of DCI (Downlink Control Information, Downlink Control Information).

Wherein, described the first Indication message is used to indicate UE and stops all or part of Downlink Control Information DCI of the dedicated search space DSS that monitors first carrier.

Concrete, in the time that UE moves to the scope that the second base station covers, UE is determined when monitoring all or part of DCI of DSS in the first base station, sends the first Indication message to UE.

Further, in the first Indication message, carry the first identification information.Wherein, described the first identification information stops the DCI of the DSS monitoring for indicating described UE.

Optionally, described part DCI comprises up DCI or descending DCI, and described the first identification information comprises: the information of up DCI or the information of descending DCI.

Wherein, described up DCI refers to the DCI for distributing ascending resource.Described descending DCI refers to the DCI for allocation of downlink resource.

Or described part DCI comprises the DCI of at least one form, described the first identification information comprises: the sequence number information of the DCI of at least one form.

It should be noted that, the sequence number information of the DCI of described at least one form refers to the sequence number information of the DCI of at least one directional information.For example, the sequence number information of up DCI.

Further, the first Indication message can be the DCI message of the DSS of deexcitation first carrier, also descending BSR (Buffer State Report, buffer status report) message.Wherein, described descending BSR message is to be sent for recording the first base station, the data volume that described UE is corresponding.

It should be noted that, the first Indication message can also be other message, and the present invention does not limit this.

It should be noted that, the first carrier of the first base station can be the main carrier of UE.

102, the second base station transmits control message that to described UE described UE is controlled by the Data Radio Bearer DRB of the second carrier wave.

Concrete, sending to UE in the first base station after the first Indication message, the first base station does not transmit control message to UE at all or part of DCI of the DSS by first carrier.The control message that need are sent to UE by the first base station is sent to the second base station, and the second base station is sent to UE to UE is controlled by this control message by DRB (Data Radio Bearer, Data Radio Bearer).

It should be noted that, described UE is controlled and can be comprised: the control that UE is measured, the control of switching, the control of cell reselection, the control of each layer parameter configuration and the control of bearer management aspect, can also be otherwise control, and the present invention does not limit this.

103, described the first base station and the second base station are jointly for described UE provides service.

Wherein, described service comprises: data, services and signaling service.

Concrete, the part DCI of DSS that stops the first carrier of monitoring the first base station at UE, after transmitting control message to UE by the second base station in the first base station, the first base station and the second base station can be UE data, services is provided, and the first base station provides signaling service for UE.

For example, communicating by letter of downlink data carried out with UE in the first base station, and communicating by letter of upstream data carried out with UE in the second base station.The upstream data that the second base station can send UE is forwarded to the first base station.

The whole DCI of DSS that stop the first carrier of monitoring the first base station at UE, after transmitting control message to UE by the second base station in the first base station, the first base station provides signaling service for UE, and the second base station provides data, services for UE.

The embodiment of the present invention provides a kind of method of the UE of control monitoring carrier wave, and the first base station sends the first Indication message to UE, to indicate UE receiving after the first Indication message, stops all or part of DCI of the DSS of the first carrier of monitoring the first base station.Now, the second base station transmits control message that to UE UE is controlled by the DRB of the second carrier wave, and the first base station and the second base station are jointly for UE provides data, services.Like this, UE monitors all or part of DCI of the DSS of the first base station without the moment, and the first base station can send control signaling to UE by the DRB of the second carrier wave of the second base station, thereby has reduced the power consumption of UE, and has improved user's experience.

The embodiment of the present invention provides a kind of method of controlling user equipment (UE) monitoring carrier wave, as shown in Figure 2, comprising:

201, receive the first Indication message that the first base station sends.

Further, the first Indication message carries the first identification information.Wherein, described the first identification information stops the DCI of the DSS monitoring for indicating described UE.

Concrete, be to move to the coverage of the second base station at UE, if the part DCI of UE without the DSS of the first carrier of monitoring the first base station determined in the first base station, send to UE the first Indication message that carries the first identification information, UE receives the first Indication message sending, and also carries the first identification information in the first Indication message receiving.In the time that UE moves to the coverage of the second base station, if the whole DCIs of UE without the DSS of the first carrier of monitoring the first base station are determined in the first base station, send the first Indication message to UE, now in the first Indication message, do not carry any identification information.

Further, the first Indication message can be the DCI message of the DSS of deexcitation first carrier.The first Indication message can also be descending BSR message.Wherein, described descending BSR message is to be sent for recording the first base station, the data volume that described UE is corresponding.

202,, according to described the first Indication message, stop monitoring all or part of DCI of described DSS.

Concrete, the DCI message of DSS that is deexcitation first carrier at the first Indication message, UE receives after the first Indication message, in the first Indication message, carry the first identification information if detect,, according to the first identification information in described the first Indication message, stop the part DCI of the described DSS that monitors described the first identification information mark.

Further, if the first identification information comprises: when the information of up DCI, the associated up-link carrier of SIB2 (System Information Block 2, system information block 2) that UE stops to described first carrier sends upstream data.That is to say, UE stops monitoring the up DCI of first carrier.If the first identification information comprises: when the information of descending DCI, stop monitoring described first carrier and descending DCI according to described the first identification information.

And UE applies a DRX (Discontinues Receive, discontinuous reception) mode parameter to carry out discontinuous reception on first carrier.Be UE the DRX mode parameter of first carrier is converted to a DRX mode parameter by the 2nd DRX mode parameter.

At traditional LTE (Long Term Evolution, the Long Term Evolution of 3GPP) in system, DRX is when UE is during in idle (IDLE) state, UE has not had RRC connection and user's specific resource, therefore be mainly the schedule information of the public control messages such as listening broadcast message and beep-page message, therefore, as long as the discontinuous receiving cycle long for UE configuration carries out PDCCH (Physical Downlink Control Channel, Physical Downlink Control Channel) blind Detecting of DCI of channel, just can reach the object of discontinuous reception.Described idle pulley DRX parameter, refer to network be UE configuration when the DRX parameter of UE during in idle condition, generally comprise DRX cycle and for calculating UE some other parameters in monitoring moment.

The DRX that also have state of activation corresponding with idle pulley DRX, the DRX of so-called state of activation refers to, UE is in the time activating (being also referred to as RRC connection status), UE is according to certain cycle, carries out discontinuously the monitoring of DCI of PDCCH to obtain schedule information, generally speaking, the cycle of the DRX of state of activation is shorter than the DRX cycle of idle pulley, the time that interior UE of each cycle need to monitor DCI is longer, so, use the DRX of state of activation than the DRX of idle pulley power saving more.

In embodiments of the present invention, in the time that UE is operated in the first base station and the second base station, although UE in state of activation, UE still uses the DRX parameter of idle pulley to carry out the monitoring of DCI on first carrier, thereby can make UE power saving more on first carrier.For example, in the time stopping whole DCI of the DSS that monitors first carrier, UE just can use the DRX parameter of idle pulley to monitor the DCI of CSS, like this, although UE still keeps being connected with the RRC of first carrier, still in state of activation, but UE is by using the DRX parameter of idle pulley can reach the better power saving effect of DRX parameter when using enable mode (or being referred to as connection status).

Wherein, a described DRX mode parameter can be the DRX parameter under idle pulley.Described idle pulley DRX parameter refers to that, when UE is when idle condition (idle mode), network is the DRX parameter of UE configuration.

The 2nd DRX mode parameter can be the DRX parameter under state of activation.DRX parameter under described state of activation refers to that UE is when state of activation (active mode), and network is the DRX parameter of UE configuration.

Optionally, UE stops (the Physical Uplink Control Channel to the up-link carrier PUCCH of the SIB2 association of first carrier, physical uplink control channel) and/or PUSCH (Physical Uplink Share Channel, Physical Uplink Shared Channel) upper feedback CQI (Channel Quality Indicator, channel quality indication), PMI, RI (RankIndication, order indication), the information such as PTI (Precoding Type Indicator, the indication of precoding type).

If described the first identification information comprises: the sequence number information of the DCI of at least one form, according to the first identification information in described the first Indication message, stops the part DCI of the described DSS that monitors described the first identification information mark.That is to say, stop the DCI of the sequence number information mark of the DCI of described at least one form of the DSS that monitors first carrier according to the sequence number information of the DCI of at least one form.

If detect in described first Indication message of reception and do not carry the first identification information, according to described the first Indication message, stop whole DCI of the DSS that monitors described first carrier.

Further, UE is in the time stopping all or part of DCI of the DSS that monitors first carrier, still keep monitoring CSS (the Common Search Space of described first carrier, public search space) DCI, thereby can continue to obtain the common control information of the first base station, keep with the first base station between be connected.

It should be noted that, UE can obtain the schedule information of public control message by monitoring the DCI of CSS, for example, and system information.UE can obtain professional message and business datum by the DCI that monitors DSS.The first base station need to be sent to public control message by the DCI of CSS all UE of the first base station service, now, public control message only need be broadcasted by the DCI of CSS in the first base station, all UE of the first base station service can receive public control message, and now the first base station can only send once public control message.

If UE stops the DCI of the CSS of the first carrier of monitoring the first base station, the first base station need send public control message one time for each UE of each its service, can produce like this wasting of resources, and increase the workload of the first base station, so UE need keep the DCI of the CSS of the first carrier of monitoring the first base station.

Optionally, can determine the time of monitoring CSS according to the DRX parameter of a DRX mode parameter.

In the situation that the first Indication message is descending BSR message, UE receives after the descending BSR message of the first base station transmission, descending BSR message can be detected, if detect, the data volume recording in descending BSR message is not more than the first threshold value, UE stops whole DCI or the whole descending DCI of the DSS that monitors first carrier, and keeps the DCI of the CSS that monitors first carrier.If detect, the data volume recording in descending BSR message is greater than the first threshold value, but is not more than the second threshold value, and UE stops part DCI or the descending DCI of part of the DSS that monitors first carrier, and keeps the DCI of the CSS that monitors first carrier.If detect, the data volume recording in descending BSR message is greater than the second threshold value, and UE keeps whole DCI of the DSS that monitors first carrier, and monitors the DCI of the CSS of first carrier.

Or, UE also can determine whether to monitor according to the up BSR of self DCI of first carrier, if detect, the data volume of up BSR is not more than the 3rd threshold value, and UE stops whole DCI or the whole up DCI of the DSS that monitors first carrier, and keeps the DCI of the CSS that monitors first carrier.If detect, the data volume recording in up BSR message is greater than the 3rd threshold value, and is not more than the 4th threshold value, and UE stops part DCI or the up DCI of part of the DSS that monitors first carrier, and keeps the DCI of the CSS that monitors first carrier.If detect, the data volume recording in up BSR message is greater than the 4th threshold value, and UE keeps whole DCI of the DSS that monitors first carrier, and monitors the DCI of the CSS of first carrier.

Or, UE receives after the descending BSR message of sending out the first base station, can detect the up BSR message of descending BSR message and UE self, if detect, the data volume recording in descending BSR and up BSR message is all not more than the 5th threshold value, UE stops whole DCI of the DSS that monitors first carrier, and keeps the DCI of the CSS that monitors first carrier.If detect, the data volume recording in descending BSR and up BSR message is all greater than the 5th threshold value, and is all not more than the 6th threshold value, and UE stops the part DCI of the DSS that monitors first carrier, and keeps the DCI of the CSS that monitors first carrier.Otherwise UE keeps whole DCI of the DSS that monitors first carrier, and monitor the DCI of the CSS of first carrier.

It should be noted that, the first threshold value, the second threshold value, the 3rd threshold value, the 4th threshold value, the 5th threshold value, the 6th threshold value all set in advance.

Or, in the time that UE receives descending BSR that the first base station issues higher than the 7th thresholding, determine that the DCI of CSS and the DCI of DS S to first carrier all monitors.Otherwise only monitor the DCI of the CSS of first carrier.

Or, when the up BSR of UE oneself is during higher than the 8th thresholding, determine that the DCI of CSS and the DCI of DSS to first carrier all monitors.Otherwise only monitor the CSS of first carrier, and do not monitor the DCI of DSS.

Or, in the time that UE determines descending BSR and up BSR all higher than the 9th thresholding, determine that the DCI of CSS and the DCI of DSS to first carrier all monitors, otherwise only monitor the CSS of first carrier, and do not monitor the DCI of DSS.

It should be noted that, the 7th threshold value, the 8th threshold value, the 9th threshold value all set in advance.

203, receive by the Data Radio Bearer DRB of the second carrier wave the control message for UE is controlled that the second base station sends.

Concrete, UE stops after all or part of DCI of DSS of the first carrier of monitoring the first base station, monitor all or part of DCI of the DSS of the second carrier wave, utilize the Data Radio Bearer DRB of described the second carrier wave to receive the control message for UE is controlled that the second base station sends.

Wherein, the schedule information of described control message is obtained from all or part of DCI of the DSS of described the second carrier wave.

It should be noted that, schedule information is the information of obtaining wherefrom data for indicating.

204, described the first base station and the second base station are jointly for described UE provides service.
