Specific embodiment
Description of specific embodiments of the present invention with reference to the accompanying drawing.
Inventor during invention note that
It is traditional with macro base station with the deployment of numerous local nodes such as more and more Home eNodeB, Microcell, relaying
Based on the network architecture network architecture that will gradually develop into more type of base station and coexist, and the network for providing more levels covers
Lid.In order to improve the correlated performance under the polymorphic type base station co-existin networks framework, one kind realizing more eNB by non-ideal link
Cooperation/polymerization network architecture is suggested between (evolution base station).Under this architecture, UE (User Equipment, user equipment)
A part carrying RB (Radio Bearer, radio bearer) MCG (Master for being managed in MeNB (Master eNB, main eNB)
Cell Group, main plot group) on, this part RB includes control plane carrying SRB (Signaling Radio Bearer, control
Face radio bearer) and user plane bearer DRB (Data Radio Bearer, Data Radio Bearer), and PCell (Primary
Cell, main plot) there is PUCCH (Physical Uplink Control Channel, Physical Uplink Control Channel) channel.And
The another part of same UE is carried on SCG (the Secondary Cell of SeNB (Secondary eNB assists eNB) management
Group, supplementary cell group) on, and a PSCell (Primary Secondary Cell, main auxiliary cell) has PUCCH.
Since UE has connection in two eNB simultaneously under the framework, it is referred to as DC (Dual Connectivity, dual link).
Fig. 1 is the network scenarios schematic diagram of dual link, in a kind of possible multitiered network overlay environment shown in FIG. 1,
Nonideal data/signaling interface Xn interface is used between MeNB and SeNB, UE may be simultaneously operated under MeNB and SeNB.When
When being connected to the UE of MeNB and entering the coverage area of cell corresponding to SeNB, MeNB can be according to signal strength or load balancing
Deng consideration, data/signaling of some or all of transfer UE obtains the service of SeNB offer to SeNB.To realize that UE can be with
It polymerize (inter-eNB polymerization) using between the resource and base station of MeNB and SeNB simultaneously.Under the scene, multiple RB of UE can
To be carried respectively by SCG cell and MCG cell respectively.The RB for being wherein separated to SeNB may include DRB and/or SRB.
Measurement interval (Measurement Gap) is illustrated below.
UE is when doing different-frequency measure, it is possible to can not the normal sending and receiving data on current service frequency point, therefore
It needs network side to configure measurement interval to UE to help UE to carry out different-frequency measure, while not will lead to the loss of UE data packet again.
The configuration at measurement interval will obey following measurement demand.According to different measurement map configuration measurement intervals, such as each of map 0
Measurement interval is 6 milliseconds, and the repetition period for measuring interval is 40 milliseconds.
The measurement interval configuration that table 1:UE is supported
For DC UE, measurement interval configuration and table 1 of the UE on PCell are identical.Current UE is on MCG and SCG
Synchronous regime be defined as follows:
Down-going synchronous state: the pointer timing differentials of the signal received from PCell and PSCell are no more than 33us.
Downlink asynchronous mode: the pointer timing differentials of the signal received from PCell and PSCell are no more than 500us.
For on PSCell, UE is used based on measuring configuration on PCell, in synchronous and asynchronous situation using in difference
It is disconnected.Fig. 2 is measurement interval and total break period (Measurement GAP and total on MCG and SCG
Interruption time on MCG and SCG) schematic diagram, wherein (a) is measurement GAP for
Synchronous dual connectivity (the GAP measurement of synchronous dual link), (b) is measurement GAP for
Asynchronous dual connectivity (GAP of asynchronous dual link is measured).As shown in Fig. 2, when UE is in synchronous shape
When state, the SCG break period of UE is 6ms；When UE is in asynchronous mode, the SCG break period of UE is 7ms.
In DC power control, when UE MCG with SCG cell send signal subframe meet uplink timing difference synchronization want
It is uplink sync status when asking, UE uses power control mode 1.
When UE MCG with SCG cell send signal subframe be more than uplink timing difference synchronize require when, be uplink
Asynchronous mode, UE use power control mode 2.
It is obtained in the offset (deviation) of SFN (System Frame Number, System Frame Number) or Subframe (subframe)
When taking, current DC is using by OAM, (Operations, Administration and Maintenance, operation are managed
Reason and maintenance) method SFN or subframe of each minizone of interaction between MeNB and SeNB offset.Uplink, MeNB
Uplink sync status is judged by the difference, and determines which kind of power control mode UE will use, and by pattern notification SeNB.
Downlink, MeNB judges down-going synchronous state by the difference, and indicates that SeNB and UE answer the measuring configuration on PSCell
Which kind of interrupt mode this uses.
For measurement event, the same frequency in LTE (Long Term Evolution, long term evolution) system/alien frequencies is surveyed at present
There are five (wherein A3 and A5 can be used for PCell and PSCell to amount event simultaneously) altogether, these measurement events are for LTE
Both for cell RSRP (Reference Symbol Received Power, Reference Signal Received Power) and RSRQ
The measurement of (Reference Signal Received Quality, Reference Signal Received Quality), comprising:
(Serving becomes better than threshold, serving cell channel quality are greater than door to Event A1
Limit)
(Serving becomes worse than threshold, serving cell channel quality are less than door to Event A2
Limit)
Event A3 (Neighbour becomes offset better than serving, adjacent cell channel quality
Better than serving cell channel quality)
(Neighbour becomes better than threshold, adjacent cell channel quality are greater than door to Event A4
Limit)
Event A5(Serving becomes worse than threshold1and neighbour becomes
Better than threshold2, serving cell channel quality is less than thresholding 1, while adjacent cell channel quality is greater than thresholding 2)
The measurement event one of the different system in LTE system shares 2 at present, comprising:
Event B1 (Inter RAT neighbour becomes better than threshold, the neighbour of different system
Cell channel quality is greater than thresholding)
Event B2(PCell becomes worse than threshold1and inter RAT neighbour
The channel quality of becomes better than threshold2, PCell are less than thresholding 1, the adjacent cell channel matter of different system
Amount is greater than thresholding 2)
CSI-RS in LTE system (channel state information reference signal, channel at present
State information reference signals) measurement event has 2 altogether, comprising:
Event C1 (CSI-RS resource becomes better than threshold, CSI-RS channel quality
Greater than thresholding)
Event C2(CSI-RS resource becomes offset better than reference CSI-RS
Resource, CSI-RS channel quality are better than referring to CSI-RS)
For uplink power control, network side can send the difference of subframe (on or according to uplink of the UE between MCG and SCG
Row synchronous regime) it is arranged whether use different power control modes.Judgement for measurement interval, network side can be according to MCG
The difference setting (or down-going synchronous state) of downlink reception subframe between SCG configures whether UE uses in different in PSCell
Disconnected duration.
Inventors noted that in the prior art, power control mode cannot be arranged, and configuration UE is used in PSCell
Interruption duration, be that MeNB and SeNB can not effectively be allowed by way of OAM due to the MeNB and SeNB for different vendor
Get the difference of the SFN and subframe of other side.Solve the problems, such as that this is just needed in such a way that UE reports notice network.But
It is that existing measurement reports in technology that there are no for reporting the effective ways of SFN and subframe difference.Based on this, the present invention is real
It applies and provides a kind of scheme for measuring and reporting in example, realize UE reporting for measurement SFN and subframe difference, to solve to set
The problem of setting power control mode, configuration interruption duration.
In declarative procedure, it will be illustrated respectively from the implementation of UE and base station side, but this does not imply that the two is necessary
Cooperation is implemented, in fact, also respectively solving the problems, such as the side UE, base station side when UE and base station are performed separately, only the two is tied
It closes in use, superior technique effect can be obtained.
