Description
Technical field
The present invention relates to communication technical field, relate in particular to method of measurement, equipment and system under a kind of carrier aggregation.
Background technology
LTE (Long Term Evolution, Long Term Evolution) is 3G (3rd Generation, third generation digital communication) evolution, LTE improves and has strengthened the aerial access technology of 3G, adopt OFDM (Orthogonal Frequency Division Multiplexing, OFDM) and MIMO (Multiple Input Multiple Output, multiple-input and multiple-output) as the standard of this LTE wireless network evolution.Wherein, the LTE system and before wireless communication system in, have only a carrier wave in the sub-district, as shown in Figure 1, the maximum bandwidth in the LTE system is 20MHz; And under the spectral bandwidth of 20MHz, LTE can provide the peak rate of descending 100Mbit/s and up 50Mbit/s, improves the performance of Cell Edge User, and improves cell capacity and reduce system delay.In addition, in the LTE system, UE (User Equipment, subscriber equipment) can only work under a carrier wave simultaneously, and a LTE sub-district has only a carrier wave, and each LTE sub-district is identified by a number unique in network.
And increasing rapidly along with the number of users of mobile terminal amount, terminal use's volume of business is exponential increase, in order to satisfy the terminal use's who continues to increase business demand, the business and the needed more peak value speed of application that need provide bigger bandwidth to satisfy the terminal use.In LTE-A (LTE-Advanced, senior LTE) system, the peak rate of system has huge raising than LTE, requirement reaches descending 1Gbps, up 500Mbps, at this moment, if only use the carrier wave of a maximum bandwidth, obviously be the requirement that can't reach peak rate as 20MHz.Therefore, the LTE-A system needs the operable bandwidth of terminal extension user, introduced CA (Carrier Aggregation thus, carrier aggregation) technology, be about to a plurality of continuous or discrete carrier aggregation (between sub-district under the different e NB or the member carrier can not polymerization) together under the same eNB (or base station), simultaneously for the UE service, so that UE to be provided required speed.Wherein, the above-mentioned carrier wave that condenses together is called CC (Component Carrier, member carrier) again.In addition, in order to guarantee that the UE under the LTE can work under the carrier wave of each polymerization, each carrier wave maximum is no more than 20MHz when requiring carrier aggregation, as shown in Figure 2, be the carrier aggregation technology schematic diagram under a kind of LTE-A, as can be seen, have under the base station of LTE-A 4 can polymerization carrier wave, transfer of data can be carried out with UE simultaneously in the base station on 4 carrier waves, to improve throughput of system.
Concrete, in the LTE-A system,, before for the UE service or when serving, need assess the channel quality of polymerizable carrier wave, and determine whether utilize this polymerizable carrier wave to carry out carrier aggregation by the base station for UE for carrier wave that can polymerization.For example, if the channel quality of certain carrier wave is better, satisfy the condition of carrier aggregation, when UE needed the large-data operation transmission, the base station can provide service for UE by this carrier wave of polymerization; If UE is carrying out the carrier aggregation transmission, and certain polymerization carrier channel degradation of serving for UE, do not satisfy the condition of carrier aggregation, then the base station can this carrier wave of deexcitation, do not utilize it to provide service for UE, also can activate simultaneously the channel quality carrier wave preferably that another one satisfies the condition of carrier aggregation, for UE provides service.
Further, in current LTE-A system, each sub-district has only a carrier wave that can work independently, and by unique GCI (Global Cell ID, Cell Global Identity) identifies (GCI also can be called ECGI, i.e. E-UTRAN Cell Global ID).When carrying out carrier aggregation, need assess the channel quality of all polymerizable sub-districts (member carrier), thereby whether utilize this polymerizable carrier wave to carry out carrier aggregation by the base station decision.As shown in Figure 3, be a kind of channel quality assessment schematic diagram.Wherein, the carrier frequency point of Cell 1 is f1, the carrier frequency point of Cell 2 is f2, the carrier frequency point of Cell 3 is f3, when needs provide service for certain UE afterwards with above-mentioned three carrier aggregation, need be to Cell 1, the channel quality of Cell 2 and Cell 3 is assessed, so that the base station can better provide the carrier aggregation transmission for UE.
In the prior art, the evaluation process of channel quality is based on the LTE system, the base station is by RRC (Radio Resource Control, radio resource control) signaling sends measurement configuration information to UE, UE measures (promptly channel quality being assessed) according to the content of this measurement configuration information, and measurement result is reported network.As shown in Figure 4, employed RRC connects the reprovision process when measuring configuration for a kind of network, comprising: network side E-UTRAN (the UMTS wireless access network of evolution) sends the RRC connection to UE and reshuffles (RRCConnectionReconfiguration) message; UE reshuffles to E-UTRAN transmission RRC connection and finishes (RRCConnectionReconfigurationComplete) message.
In summary it can be seen, at least have following shortcoming in the prior art: in the prior art only at the channel quality assessment method of LTE system, when having introduced carrier aggregation technology in the LTE-A system, can't adopt prior art to realize for the channel quality assessment of polymerization carrier wave.
