Description

Determine, monitor main carrier and the method for instruction activation carrier wave, system and equipment

Technical field

The present invention relates to the communications field, particularly relate to and a kind ofly determine main carrier and method, system and equipment that main carrier is monitored, and a kind of instruction is activated carrier wave and utilize the method, system and the equipment that activate carrier transmission data.

Background technology

Along with the development of communication system, to the quantity of transfer of data and the requirement of speed more and more higher, therefore, the basis of Long Term Evolution standard (Long term evaluation, LTE) proposes the evolution version lte-a system of LTE.The peak rate of LTE-A comparatively LTE improves a lot, and require that downstream rate reaches 1Gbps, upstream rate reaches 500Mbps.Because traditional single-carrier system cannot meet the demand of LTE-A transmission rate, therefore, carrier aggregation (Carrier Aggregation is introduced in LTE-A, CA) technology, namely in same community, multiple continuous or discrete carrier wave is concentrated in together, become polymerization carrier system, the multiple carrier waves in carrier aggregation system can be Terminal Service simultaneously, speed required during to provide downstream transmission.

Each carrier wave in polymerization carrier system is called the member carrier (Component Carrier, CC) of community.In order to keep the backwards compatibility to LTE R8 terminal, the Physical Resource Block (physicalresource block, PRB) of each member carrier is no more than 110.

As shown in Figure 1, suppose LTE-A cell aggregation 4 carrier waves, be respectively Carrier_1 ~ Carrier_4, the bandwidth of each carrier wave is not more than 20MHz.Transfer of data can be carried out with terminal, to improve the transmission rate of lte-a system in base station simultaneously on these 4 carrier waves.

As shown in Figure 2, be the frame structure schematic diagram of descending sub frame.Each descending sub frame is made up of seven OFDM symbol, wherein: last is control character to four OFDM symbol, and for bearing downlink control signal, the physical channel of bearing downlink control signal is called PDCCH channel.Remaining OFDM symbol is used for bearing downlink data, and the physical layer channel of bearing downlink data is called PDSCH channel.Control signal comprises: to the schedule information and relevant HARQ information etc. of this descending sub frame and corresponding sub-frame of uplink.

In LTE system, terminal needs to monitor descending carrier, is determined whether as this terminal is assigned with resource in corresponding subframe by the control signal receiving descending sub frame.If the resource of being assigned with, then terminal obtains the time-frequency domain position of resource according to the instruction of dispatch, and utilizes this resource to carry out data transmit-receive.

Be single-carrier technology due to what adopt in LTE system, each community only has a downlink member carrier, and therefore, terminal only needs PDCCH and PDSCH on monitoring descending carrier.But for lte-a system, the multiple member carrier of a community possible configuration, LTE-A terminal may use multiple member carrier to carry out transfer of data (the member carrier quantity simultaneously used is not more than the member carrier quantity of configuration) simultaneously, therefore, the monitoring mechanism of LTE system cannot directly be applied in lte-a system.

Consider the particularity of lte-a system structure, now propose a kind of new monitoring mechanism, require the PDCCH channel on a special member carrier wave in terminal monitoring carrier aggregation system and PDSCH channel.Transfer of data main carrier, also referred to as the particular data transmission main carrier (UE-specific anchorCC) of terminal, for convenience, is referred to as main carrier in the application by special member carrier wave here.When base station needs to carry out data transmit-receive with terminal, the main carrier monitored by terminal is sent control signaling to terminal, carry in the control signal sent and need to monitor and the mark of member carrier for transfer of data, needs described here are monitored and member carrier for transfer of data is referred to as to activate carrier wave.After terminal receives described control signal, according to the mark activating carrier wave, start the monitoring to corresponding member carrier, and then utilize the member carrier monitored to complete the communication with base station.

In the monitoring mechanism of above-mentioned lte-a system, also do not determine the relevant programme of the main carrier of terminal, if only select arbitrarily a member carrier as main carrier simply from polymerization carrier system, occur that main carrier owing to selecting and terminal capability do not mate the monitoring that the causes problem such as unsuccessfully possibly.Meanwhile, when having bursty data to need to transmit between terminal and base station, base station needs to activate multiple member carrier, and terminal carries out data transmit-receive simultaneously on the member carrier of multiple activation; When the data volume transmitted between terminal and base station reduces, base station needs to reduce the membership activated.But do not determine in the monitoring mechanism of existing lte-a system to activate the number of carrier wave and the scheme selecting which member carrier as activation carrier wave yet.

3rd step: network side for parameter, determines the weighted value of each candidate carrier with the terminal quantity of correspondence and channel quality parameter value.

In this step, candidate carrier weighted value is calculated by formula (1) to be determined:

${\mathrm{PRI}}_i=P1*\frac{X}{\mathrm{UE}\_\mathrm{NUM}\_\mathrm{ANCHOR}\_{\mathrm{CC}}_i}+P2*\frac{\mathrm{CQI}\_{\mathrm{CC}}_i}{Y}...\left(1\right)$

Wherein, PRI _irepresent the weighted value of i-th the second candidate carrier, 1≤i≤the second candidate carrier quantity; P1, P2 represent weighted factor, P1+P2=1; UE_NUM_ANCHOR_CC _irepresent the terminal quantity that i-th candidate carrier is corresponding; CQI_CC _irepresent the channel quality parameter value of i-th the second candidate carrier; X and Y is fixed value;

3rd chooser module, for when the second candidate carrier quantity is greater than the activation number of carriers of needs, from the second candidate carrier, select N number of second candidate carrier as activation carrier wave, the weighted value of N number of second candidate carrier wherein selected is greater than weighted value corresponding to unselected second candidate carrier; Otherwise, using the second candidate carrier all as activation carrier wave;

Terminal, for monitoring according to the activation carrier wave of mark to correspondence of the described activation carrier wave received, and the described activation carrier transmission data by monitoring.
