, first will definition and call for Votes as the part of this solution.To introduce power conservation feature, in LTE Rel-10
The middle support for requiring increase transmission (DTX) discontinuous to eNB.It can be considered that several different types of downlink DTX.In LTE
In the context of the downlink (DL) of 3 types, DTX patterns can be defined：Short DTX can be defined as complete with LTE Rel-8
The DTX of back compatible.Substantially, short DL DTX thus be restricted to one and arrive several OFDM symbols, wherein, without transmitting cell spy
Determine reference symbol.Middle DTX can be defined as the DTX with the non-back compatibles of Rel-8, i.e. be longer than a subframe (1ms) but be shorter than one
The DTX duration of a radio frame (10 ms).Finally, long DTX can be defined as making carrier wave also invisible to Rel-10 UE
The DTX duration, i.e. equal to the DTX duration of one or several radio frames.Long DL DTX may also be expressed as eNB
Sleep.
At first sight, it is introduced into LTE Rel-10 in or the support of long eNB DTX is seemingly quite direct.Fig. 1
LTE radio frames with 72 center sub-carriers are shown, introduce the eNB of 4 ms in subframe no. 1,2,3,4,6,7,8 and 9
DTX.For example, LTE Rel-10 specifications can be altered slightly, so as to user plane data business it is few or there is no when, eNB need not
Cell specific reference symbol (CSRS) is transmitted in each subframe.In this example, it is to force that CSRS, which can only have in subframe 0 and 5,
, master sync signal (PSS) and auxiliary synchronous signals (SSS) and broadcast channel (BCH) are also transmitted in the two subframes.CSRS
Need to transmit in those subframes of carrying system block of information (SIB).SIB1 is passed in the 5th subframe of each radio frame
Sending, SIBx may be configured with extremely low duty cycle, wherein, x>2.In order to allow this configuration, such as the UE rows that standard is specified can be changed
For only to allow UE to perform mobility measurements during subframe 0 and 5.
The fact that CSRS is not transmitted in each subframe also can similarly influence channel quality indicator (CQI) measurement.So
And may have been specified in Rel-8 will perform CQI measurements at what time., be before scheduling UE reports CQI in Rel-8
4 subframes perform CQI measurements.The time domain filtering of CQI estimations is not performed in UE.Whether may must rethink this mechanism
It is abundant to Rel-10, or whether require certain other flexibility.
If UE measures CQI in the subframe outside subframe 0 and 5, they cannot assume that there are any frequency dependence, because
For eNB CSRS can not be transmitted in all resource blocks all the time.Alternatively, UE is able to detect that need not come from UE as eNB
Any CQI report instruction " complete zero CQI " measurement.
UE channel estimations are also impacted.Since UE cannot utilize time and the frequency dependence between resource block（Unless it
It is adjacent with subframe 0 or 5）, therefore, it is contemplated that channel estimation accuracy will be reduced somewhat.However, for TDD, situation has been this
Sample, in TDD, since some subframes are UL subframes, cannot carry out interpolation between all subframes.Therefore, this is not base
This problem.
Solution shown in Fig. 1 summaries has many alternative.UE mobility measurements can be limited to：
6 ,-center resource block；And/or
- single antenna port（For example, antenna port 0）；And/or
- only PSS and SSS signals；And/or
- only subframe 0, i.e. be not such as two subframes 0 and 5 in Fig. 1.
May also future non-legacy LTE releases（For example, Rel-10）Ginseng is defined for the extension carrier wave of non-back compatible
Examine the new set of symbol.Being currently discussed in 3GPP mentions two new set of reference symbol：Demodulation reference mark (DM-RS) and
Channel condition information reference symbol (CSI-RS).If new reference symbol is defined（For example, the shifting of above-mentioned CSI RS or DM-RS
The new set of dynamic property measuring reference signals）, then UE mobility measurements may be defined in the subset of new reference symbol.
In order to realize the DTX phases for being longer than 4 ms, we are it is envisioned that eNB sleep patterns are also defined for LTE Rel-
9 or LTE Rel-10.The eNB of sleep can periodically be transmitted during the short movable duration such as 50 ms UE measurement and it is attached
It is connected to all signals needed for cell, i.e. PSS, SSS, BCH, SIB1, SIB2, CSRS.Be after active stage it is more much longer not
Active stage, such as 450 ms, during this period, eNB does not transmit any signal.Active stage, can be with LTE Rel-8 or such as LTE
Release is compatible after Rel-10 etc..
The problem of related with above-mentioned energy saving solution is that user equipment cannot access cell in DTX patterns, because DTX
Cell in pattern is sightless to this user equipment, and serving BS will not connect from the user equipment that can trigger switching
Receive any handover measurement.
Therefore, the further object of this solution is to provide the mode of requirement so that it is small that user equipment accesses non-observable
Cell that is in zone state and therefore not transmitting any signal is possibly realized, or the DTX patterns that access user equipment is not supported
In cell.
Fig. 2 shows radio communications system 100, such as also referred to as E-UTRAN, LTE-Adv of LTE, third generation affiliate
The evolved enhancing data transfer rate (GSM/EDGE) of project (3GPP) WCDMA system, global system for mobile communications/GSM, wideband code division
Multiple access (WCDMA), inserting of microwave worldwide interoperability (WiMax) or Ultra-Mobile Broadband (UMB).Radio communications system 100
The Standardized wireless electricity specification of different releases is held, such as standardizes LTE specification or standardization high-speed packet access (HSPA) specification.
Radio communications system 100 includes the first base station 110 serviced for first community 115.First base station 110 can be
The base stations such as NodeB, eNodeB or can be communicated by radio carrier with the user equipment in first community it is any its
Its communication unit.First base station 110 is communicated by radio carrier 125 with the user equipment 120 in first community 115.First
Cell 115 is in an active mode, it means that and the radio carrier 125 in first community 115 is normal and running, such as
The DTX patterns supported with user equipment 120.Activity pattern in this context represents serving cell（That is first community 115）
Transfer mode data communication may be carried out between user equipment 120 and first community 115.Therefore, such as set from user
For standby 120 angle, only serving cell（That is first community 115）Can in an active mode, and non-service cell（I.e.
Two cells 134）Cannot be in an active mode.However, non-service cell（That is second community 135）Can be in user equipment observable
Or in the DTX patterns of non-observable.In the figure 2 example and only for purposes of illustration only, first base station 110 also passes through other radio
Carrier wave 129 communicates with other user equipmenies 127 in first community 115.User equipment 120 can be mobile phone, a number
Word assistant (PDA) can pass through radio channel and any other network unit of base station communication.
Radio communications system 100 further includes the second base station 130 serviced for second community 135.Second base station 130 can be with
NodeB, eNodeB when base station or can cell status in an active mode when it is small with second by radio carrier
Any other network unit of user equipment communication in area 135.However, in fig. 2, second community not in an active mode,
But in the pattern of non-observable, it means that for the angle of user equipment 120, the carrier wave in second community 135 is not
Transmitting any signal, or it is in the DTX patterns that user equipment 120 is not supported.Note that it may consider in such as 3GPP
The situation of new DTX patterns is introduced in the new issue version of the standardized system specification such as LTE.In this case, new standard hair is only met
The cell of new DTX patterns operation is used that can observe for the user equipment of row version.Therefore, user equipment observable
DTX patterns may be non-observable to another user equipment.
The general conception of this solution will now be described.In the example case with reference to Fig. 2, user equipment 120 will be logical
Cross the second base station 130 and second community 135 is preferably serviced.Second community 135 in the pattern of non-observable to
Family equipment 120 is sightless.
Start user equipment 120 being switched to the handoff procedure of second community 135, first base station 110 asks the second base
Stand 130 patterns that second community base station is transformed into observable from the pattern of the non-observable for the user equipment 120.Can
The pattern of observation means that for the angle of user equipment 120 carrier wave in second community 135 is temporarily with user equipment
The 120 DTX patterns supported are transmitted, and are intended merely to the purpose for allowing mobility measurements.But user equipment 120 or second community
Any other user equipment in 135 not actively receives the user plane data on carrier wave.
Second base station 130 is by second community State Transferring to the pattern of the observable for the user equipment 120.This turn
Changing makes second community 135 become to be visible user equipment 120.
First base station 110 then asks 120 or second base station 130 of user equipment in 120 and second base station 130 of user equipment
Between perform signaling for mass measurement.
The mass measurement of signaling based on execution, first base station 110, which obtains, switches feasible information.
Then the second base station 130 of request prepares the switching that user equipment 120 arrives second community 135 to first base station 110, and
Order user equipment 120 goes to the switching of second community 135.
Switching to second community is performed by user equipment 120, is terminated with the situation shown in Fig. 3.Change the second base station 130
To activity pattern.110 and second base station 130 of user equipment can then start to be in communication with each other by radio carrier.
Due to this solution in above-mentioned and following methods, cell can ask non-observable neighbor cell to be changed into observable
's.
Thus, for example, when loading high, it can check whether any neighbor cell being capable of adapter one for the base station of cell serves
A little business.
In this solution, pattern term is defined from the angle of user equipment 120.Therefore, it is possible in " activity " pattern
In only serving cell, i.e. first community 115.As long as involve this user equipment 120, non-service cell（That is second community
135）Just it is merely able to be " observable " or " non-observable ".Second community 135 can also be " observation ", but it cannot be
" movable ", at least performed in user equipment before the switching of second community 130 cannot, after the handover, second community
135 are just no longer known as second community 135.Furthermore, it is noted that term " observable " represents to can determine that 120 and second base of user equipment
The characteristic for the radio channel stood between 130.Therefore, term " observable " is used to describe the transmission of second community 135 with reference to letter
Number and the user equipment 120 can perform the situations of mobility measurements in the reference signal, and second community 135 prepares
Perform the situation of the measurement in the reference signal that the user equipment 120 transmits needed for mobile sex determination.
By first community 115（I.e. first community 115 therefore in " activity " pattern）The user equipment 120 serviced is not examined
Consider whether second community 135 just actively services for some other user equipmenies 127.Unless we assume that in activity pattern
Any cell automatic phasing adjacent cell in all user equipmenies be also observable, otherwise, second community 135 is in movable mold
It is incoherent in formula.Situation may not be in this way, because second community 135 may be LTE using Rel-10 transformats
Rel-10 user equipment services, therefore, for the angle of this user equipment, it in an active mode, and in neighbor cell
User equipment be probably the Rel-8 user equipmenies that can not be measured on this form, therefore, from the angle of this user equipment and
Speech, second community is non-observable.Therefore, when reading " observable " and " non-observable ", this is from user equipment
For 120 angle.To a user equipment（For example, Rel-10 user equipmenies）It is observable, but to another user equipment
（For example, Rel-8 user equipmenies）It can be non-observable.Term " observable " also refers to the signal specific that second community is known
On measurement just transmitted from the user equipment 120 serviced by first community 115.
Therefore ...
" activity pattern " is used for the pattern for describing the currently cell for user equipment service.
" non-observable " or " observable " pattern are used to describe whether can determine 120 and second base station of user equipment
The characteristic of radio channel between 130.
If second community 135 is " non-observable ", it, which can be requested, becomes " observable ", that is, starts basis
The form that user equipment 120 can measure sends reference signal；Or it is ready to pass in the channel detection from user equipment 120
Serve and measure.Before user equipment 120 enters second community 135, whether second community 135 is that " movable " does not weigh
Will.
Note that to simplify description of the invention, the situation of each cell transmission single carrier wave is only described.If from a base
