Description
Technical field
The present invention relates to wireless relaying technique, particularly a kind of transmission quality indicates method of adjustment, device and base station.
Background technology
In order to tackle the wireless propagation environment of various complexity, (Long Term Evolution, drill for a long time to solve future LTE
Enter) covering problem of network design, 3GPP (3rd Generation Partnership Project, the 3rd generation Partnership Program)
Relaying (Relay) node is standardized in LTE-Advanced R10 release protocols.By in macro base station and user
A via node is added between equipment, as shown in figure 1, the link that direct transfers between macro base station and user equipment is divided into two sections：
Radio Link between macro base station and relaying is referred to as return link (Un interfaces), and the Radio Link between relaying and user equipment claims
It is access link (Uu interfaces).Reasonably disposed by via node, two after fractionation section link can have than straight
The shorter propagation distance of link is passed, while the shelter in round can also be reduced so that two sections of links after fractionation all have
There is the transmittability of radio propagation conditions more more preferable than the link that direct transfers and Geng Gao.
However, existing above-mentioned network structure is at least present because the rapid fluctuations serious interference of RN systems influences grand UE
The performance of (macro-UE, MUE), while traditional OLLA (Open Loop Link Adaptation, open loop link self adaptation)
Scheme cannot apply the problem in this kind of scene, describe in detail as follows.
In lte-a system, primary concern is that 1 type relays (Type-1RN), this RN possesses oneself independent honeycomb
Cell ID (Cell ID), the cell independent equivalent to.
Consider the relay system of 1 type relaying composition, UE such as compares and come from by choosing selection (cell selection)
Base station (Donor eNB, DeNB) and RN Reference Signal Received Power (Reference Signal Receiving Power,
RSRP) or Reference Signal Received Quality (Reference Signal Received Quality, RSRQ), selection is to access
DeNB or RN.For UE, when cell selection is carried out, DeNB and RN is equivalent.
MUE is directly to the UE of DeNB.This UE is subject to two kinds of interference：The first interference comes from adjacent area macro station
Interference, second interference comes from the interference of RN, as shown in Fig. 2 the wherein mainly interference of the RN in same cell.
Wherein, the first interference is traditional adjacent area interference, and its disturbance regime, level are identical with traditional system without RN
Or it is relatively low.Second interference is the distinctive interference of RN systems, its interference for mainly coming from RN under same cell (DeNB).
RN is different with DeNB, its return link (Backhaul Link) subframe and access link (Access Link)
Frame is using TDM modes.In Backhaul Link subframes, RN operation of receiver receives the signal from DeNB, now,
The emitter of RN is the not sending signal mourned in silence, i.e., in the absence of the interference of RN to MUE.However, in Access Link subframes,
RN gives RUE sending signals, and now, MUE can be disturbed by from RN.Therefore, in different time phases, it is dry that MUE is subject to
Disturb level fluctuation violent, forbidden so as to cause CQI (channel quality instruction) to report, the hydraulic performance decline of MUE.
In traditional LTE system, in order to resist disturbance fluctuation and the inaccurate problems of CQI, the machine of OLLA is widely used
Make, its general principle is：When the correctly demodulation transmission block at the T0 moment, one is added to CQI when next moment T0+1 sends
Modulation coding mode (MCS) is determined after individual less biasing again；And when mistake is demodulated at the T0 moment, in next moment T0+1
During transmission a larger biasing is subtracted to CQI.This scheme is primarily adapted for use in the more slow situation of the interference variations in macro station,
Because now OLLA can follow the trail of the change of interference.However, in RN systems, the fluctuation of interference exists mainly due to frame type
Change causes between Backhaul Link and Access Link, and now, the change of interference is very frequent, and traditional OLLA without
Method follows the trail of upper quick interference variations frequency.
