Description

Poor method of measurement and the equipment of timing on a kind of auxiliary community
Technical field
The present invention relates to communication technical field, relate in particular to poor method of measurement and the equipment of timing on a kind of auxiliary community.
Background technology
(1) carrier aggregation technology.
LTE-A(LTE Advanced, senior LTE) peak rate than LTE(Long Term Evolution, Long Term Evolution) improve a lot, require to reach descending 1Gbps up 500Mbps, and LTE-A system requirements and LTE system have good compatibility.Based on improving peak rate, with LTE system compatible and make full use of the needs of frequency spectrum resource, in LTE-A system, introduce CA(Carrier Aggregation, carrier aggregation) technology.
Carrier aggregation technology refers to UE(User Equipment, subscriber equipment) the multiple cell(of polymerization community simultaneously), and multiple cell can provide the mechanism of data transport service simultaneously for UE.In carrier aggregation system, the carrier wave that each cell is corresponding can be continuous or discrete on frequency domain, and for LTE system compatible, the maximum bandwidth of each member carrier is 20MHz, the bandwidth between each member carrier can be identical or different.
In carrier aggregation system, a little PCell(Primary cell, the main plot divided into of UE work) and several SCell(Secondary cell, auxiliary community); Most of control and the work of signaling born in main plot, and as sent uplink feedback, the CQI(Channel Quality Indicator to downlink data, channel quality is indicated) report, ascending pilot frequency transmission etc.; Data-transformation facility is born mainly as resource in auxiliary community.
(2) the many TA of Multi-TA() scene.
Current LTE-A R10 only supports single TA(Timing Alignment, Timing Advance) scene, i.e. the TA of all communities of UE polymerization is identical; But in LTE-A R11, introduced the scene of many TA, i.e. the TA of all communities of UE polymerization may be different.The scene that produces many TA comprises: Inter-band(frequency band) CA and Intra-band CA, but in band, part cell, through RRH(Remote Radio Head, zooms out antenna) or repeater(repeater).Concrete, as shown in Figure 1A-Fig. 1 D, the typical scene of many TA of 3GPP definition comprises:
A, UE polymerization F1 and F2, F1 coverage is less than F2, and F1 and F2 belong to different band, i.e. inter-band CA, as shown in Figure 1A.
B, UE polymerization F1 and F2, and F1 and F2 belong to different band, i.e. inter-band CA, as shown in Figure 1B.
C, UE polymerization F1 and F2, F1 and F2 belong to identical band and F2 process repeater, and the transfer of data of intra-band CA and part cell is through repeater, as shown in Figure 1 C.
D, UE polymerization F1 and F2, F1 and F2 belong to different band and F2 process repeater, and the transfer of data of inter-band CA and part cell is through repeater, as shown in Figure 1 C.
E, UE polymerization F1 and F2, F1 and F2 belong to identical band and F2 process repeater, and the transfer of data of intra-band CA and part cell is through RRH, as shown in Fig. 1 D.
F, UE polymerization F1 and F2, F1 and F2 belong to different band and F2 process repeater, and the transfer of data of inter-band CA and part cell is through RRH, as shown in Fig. 1 D.
It should be noted that for the ease of the TA of many TA system is safeguarded, the current TA group(group of having introduced) concept, belonging to same TA group(is TAG) cell, its UL CC(uplink member carrier) can use identical TA value; Belong to the cell of different TA group, the TA value of its UL CC is not identical.In a TA group, UE only needs He Yige community to keep uplink synchronous, can realize the uplink synchronous to all communities in TA group.
In addition, for the TA group under the PCell of UE configuration can not change, but which TA group the SCell configuring for UE belongs to, and will depend on eNB(base station) configuration.
(3) uplink synchronous.
Uplink synchronous process is for keeping the uplink synchronous of UE and base station, so that UE carries out transmitting uplink data and downlink data is sent to HARQ(Hybrid Auto Repeat request, mixed automatic retransfer request) feedback information.In LTE system, by base station maintenance uplink synchronous; In the time that UE accesses at random, base station is leading according to preamble() obtain initial Timing Advance, follow-up uplink synchronous maintenance process is as shown in Figure 2.
Concrete, base station and UE safeguard respectively a TAT(TA timer, upstream synchronous timing device), base station sends TA command(order to UE), and start the TAT of base station; If UE can not correctly receive TA command, base station, after a while after T1, resends TA command, and restarts the TAT of base station; UE correctly receives after TA command, starts the TAT of UE, and sends ACK(confirmation to base station) information; After base station receives the ACK information of UE transmission, restart the TAT of base station.
Base station does not have overtime for the TAT of certain UE, base station thinks that this UE is in synchronous regime; As long as it is overtime that the TAT that UE oneself safeguards does not have, UE also thinks it oneself is synchronous.
Realizing in process of the present invention, inventor finds at least to exist in prior art following problem:
Whether how be still not clear at present eNB is the TA group under UE configuration SCell, identical for the up timing of multiple intercarriers that is UE polymerization, also has relation with the residing position of UE; For example, for the scene e shown in Fig. 1 D, the up timing of UE on F2 whether with F1 on difference, directly depend on UE whether be positioned at Repeater within or outside.
