Description
Technical field
The present invention relates to wireless communication technology field, relate in particular to a kind of UE that is applied to particular carrier and measure control method and UE.
Background technology
(1) CA (Carrier Aggregation, carrier aggregation) technology introduction
The peak rate of LTE-A (Long Term Evolution-Advanced, Long Term Evolution strengthens) system improves a lot than the LTE system, requires to reach descending 1Gbps, up 500Mbps.Simultaneously, there are good compatibility in LTE-A system requirements and LTE system.Based on improve peak rate, with LTE system compatible and the needs that make full use of frequency spectrum resource, the LTE-A system has introduced CA (Carrier Aggregation, carrier aggregation) technology.
Carrier aggregation technology is that terminal can be worked on a plurality of sub-district cell simultaneously, a cell comprises the descending DL CC of a pair of up UL/ (member carrier, Component Carrier), rather than have only in LTE system and the wireless communication system before one the cover carrier wave pattern.Each member carrier can be continuous in the system of carrier aggregation, also can be discontinuous, bandwidth between each member carrier can be identical or different, in order to keep system compatible with LTE, the maximum bandwidth limit of each member carrier is 20MHz, each CC is a sub-district, it is generally acknowledged that at present the CC maximum number is 5.In addition, LTE-A also classifies to the cell of carrier aggregation, is divided into:
-Pcell (Primary Cell, main plot): have only a cell to be defined as Pcell among the cell of UE polymerization;
-Scell (Secondary Cell, auxilliary sub-district): other cell except Pcell of UE polymerization is called Scell.
Pcell is by base station selected and dispose to terminal by RRC (Radio Resource Control, Radio Resource control) signaling, and the Pcell of different terminals can be different.The difference of Pcell and Scell is that Pcell and multiple function bind in LTE R10 version, and the major function of Pcell binding is as follows:
-have only Pcell to dispose PUCCH (Physical Uplink Control Channel, Physical Uplink Control Channel), be used to transmit CQI (Channel Quality Indicator, the channel quality indication)/ACK (Acknowledgment, positive acknowledgement)/SR (Scheduling Request, dispatch request);
The descending UL timing reference carrier wave (UL timing reference) that inserts at random that can be used as of-Pcell;
-Pcell can be used as the path loss of Pcell and other Scell with reference to pathloss reference;
-have only and can carry out RA (Random Access inserts at random) process on the Pcell;
-have only Pcell to go up configurable SPS (Semi-Persistence Schedule, semi-continuous scheduling) resource;
-have only Pcell to go up generation RLF (Radio link failure, Radio Link Failure), think that just RLF takes place terminal.
(2) TDD (Time Division Duplexing, time division duplex) UL/DL disposes introduction
In LTE R8/9 version, physical layer standard at TDD system definition following seven kinds of UL/DL configuration, as shown in table 1, wherein D represents the DL subframe, U represents the UL subframe, S represents the special subframe of TDD system.
Table 1TDD UL/DL configuration
In LTE R11 version, the LTE-A system adopts the terminal of CA can share or use adjacent frequency band with other system (such as the LTE system), such as shown in Figure 1, the terminal polymerization of LTE-A system three sub-district: Cell1, Cell2 and Cell3.Wherein Cell1 uses identical frequency band Band1 with Cell2, and Cell3 uses Band2.For fear of TDD system up-downgoing cross interference, Band1 should use the TDD UL/DL configuration that can coexist with adjacent 3G/LTE TDD Band A, the so-called TDD configuration that can coexist, be meant the configuration that does not have the UL/DL cross interference, for the LTE system, what refer to is exactly identical TDD UL/DL configuration.Band2 then should use the TDD UL/DL configuration that can coexist with adjacent 3G/LTE TDD Band B.If Band A is different with the TDD UL/DL configuration that Band B uses, the TDD UL/DL configuration of Band1 and Band2 use is also just inequality so.
It should be noted that if terminal can a plurality of different B and of polymerization, and different B and can support different TDD UL/DL configurations that so in general terminal can be used different transceivers at different B and.
(3) measurement mechanism of LTE-A system
In the LTE-A system, the base station sends measurement configuration information by the RRC signaling to UE, and UE carries out (with frequency, alien frequencies, different technology) according to the content of measurement configuration information and measures, and then measurement result is reported network.
What 1) network was measured the configuration use is that RRC connects the reprovision process, and the institutional framework of measurement configuration information is as follows:
A) measuring object (measurement object): with the frequency is base unit, and each measuring object that is configured is an independent frequency, has independent measuring object sign (ID).
B) report configuration (report configuration): be divided into Event triggered and report to trigger with the cycle and report according to triggering type, each reports configuration to have independent ID.The threshold value that reports the some incidents of configuration meeting dispensing of Event triggered type and the duration (Time to Trigger) of satisfying trigger condition, the purpose that reports configuration meeting dispensing periodic triggers (for example, reporting CGI) of periodic triggers type.
LTE is intrasystem at present has six with frequency/different-frequency measure incident Event one, comprising:
-Event A1 (Serving becomes better than threshold, the Serving cell channel quality is greater than thresholding);
-Event A2 (Serving becomes worse than threshold, the Serving cell channel quality is less than thresholding);
-Event A3 (Neighbour becomes offset better than PCell, the adjacent cell channel quality is better than the PCell channel quality);
-Event A4 (Neighbour becomes better than threshold, the adjacent cell channel quality is greater than thresholding);
-Event A5 (PCell becomes worse than threshold1and neighbour becomes better than threshold2, PCell channel quality are less than thresholding 1, and the adjacent cell channel quality is greater than thresholding 2 simultaneously);
-Event A6 (Neighbour becomes offset better than SCell, the co-frequency neighbor cell channel quality is better than the SCell quality).
C) measure sign (measurement ID): independent ID can connect a measuring object simultaneously and report configuration.Open the thresholding of measuring if reached, UE can judge whether to carry out this kind measurement according to measuring having or not of sign.
D) other parameters: also may comprise the measuring amount configuration, measure other parameters such as opening thresholding and speed state parameter.
2) measure and to have reported three kinds of triggering modes: Event triggered reports, periodic report, Event triggered periodic report.These three kinds of modes are according to reporting in the configuration combination of various parameters to distinguish.
(4) measure the configuration that starts thresholding
UE in the LTE system is operated on the single carrier, and network side is that one of UE configuration is measured and started thresholding s-Measure, when the channel quality of service carrier wave is lower than s-Measure value, all measurements that the UE startup is disposed.Particularly, network side connects among the measurement configuration IE in the reallocation message configuration pin to the s-Measure value of current service carrier wave at RRC.
Specific to being provided with of s-Measure parameter value, (Radio Resource Management, RRM) factor such as algorithm is relevant with the RRM of noise circumstance, coverage and the network side of current service cell region.
The LTE-A system compares the LTE system and does not strengthen on the measurement Initiated Mechanism, just the Serving cell in the LTE system is replaced with the PCell in the LTE-A system.The measurement of controlling whole UE level by the quality of PCell starts and closes.
Current LTE-A system only considers the sub-district polymerization of identical TDD configuration, and the measurement of UE starts and closes that the quality that all is based on Pcell carries out.The following a plurality of TDD sub-district that will consider on the UE polymerization different frequency range of using, the TDD configuration of these sub-districts can differ from one another.Still can operate as normal under the situation of the different TDD UL/DL of configuration on different carrier/frequency band for the terminal that guarantee to adopt CA, may need is that each TDD UL/DL configuration set is introduced a particular cell.The quality management of particular cell and main plot Pcell have similar demand, but current not at the measuring management scheme of this class sub-district, and the current measurement that only relies on the Pcell quality to carry out starts the quality management problem that can not solve particular cell.
