Abstract
The invention provides a method for triggering time alignment of cells, in particular to a communication method for a user terminal of a wireless communication network, wherein the user terminal is configured with a primary cell and at least one secondary cell, and a first secondary cell of at least one secondary cell is in a configured and non-uplink synchronous state. The method comprises the step that the measurement of a downlink channel is not carried out. The user terminal can trigger the random access procedure according to a media access layer control signaling received by the user terminal, or the physical downlink control channel order information as mandatorily stipulated must be sent before the media access control layer control signaling in a base station or the media access control layer control signaling is sent before the physical downlink control channel order information in the base station. In addition, when the first secondary cell is set in a deactivation state in the media access control layer control signaling by the base station, the user terminal can enter a configured and uplink synchronous state according to the detected physical downlink control channel order information aiming at the first secondary cell.
Description
Technical field
The present invention is based on the radio communication of carrier aggregation technology, relate in particular to the method for triggering time unifying process from the sub-district.
Background technology
A user terminal has only after its uplink time synchronized, just can carry out correct up feedback.Therefore, in order to receive the downlink data from the base station, user terminal must be set up uplink synchronous.Otherwise, if a user terminal hopes that to the base station transmits upstream data it also should set up uplink synchronous with the base station.
Under non-situation with the site; For example; In order to support long distance wireless head (Remote Radio Head; RRH) or the scene of the relaying selected of frequency, RAN 51 has agreed to support multiple time unifying/(the Time alignment/Time Advancement) in advance of carrier aggregation (CA, Carrier Aggregation).Also promptly, support to carry out signaling and transfer of data according to line time on different on a plurality of carrier components between base station and the user terminal, below; The carrier component that user terminal is successfully inserted first is called main plot (Primary Cell; Pcell), other subsequent use carrier components be called from the sub-district (Secondary Cell, Scell); Certainly, user terminal also can correspondingly change according to the triggering of base station to the main plot with from the selection of sub-district.
RAN2 73bis has confirmed research, and (Physical Random Access Channel, PRACH) scheme is to solve the time unifying of Scell based on the Physical Random Access Channel of Secll.For time unifying, for example, up time unifying, the time calibration of also promptly carrying out uplink is through using regularly in advance in the UE side, to offset transmission delay etc.
For the PRACH based on Scell, the primary problem that solves is how to trigger the time unifying problem of Scell.
For R11 (version 11), will support a plurality of times in advance.Some need be on any from the sub-district/be in up time unifying state before the downstream operation.According to current state, exist two kinds of schemes in order to trigger the up time unifying process of Scell:
Scheme 1:UE automatically triggers the PRACH process after receiving RRC (Resource Radio Control, the radio resource control layer) configuration messages that is used for Scell purpose is set;
Scheme 2:, trigger the PRACH process through for example Physical Downlink Control Channel order signaling (Physical Downlink Control Channel, PDCCH order information) from eNB.Comprising special leader sequence in the PDCCH order signaling, also is random access lead code, is used for indicating user terminal and carries out non-competing random access procedure.
The advantage of first kind of scheme do not need to be extra PDCCH order signaling, but must strengthen present RRC configuration messages, and for example therefore joining day alignment requirement indication, special-purpose leading indication have caused extra RRC message overhead.
The advantage of second kind of scheme is the not influence of present RRC configuration messages, but PDCCH order signaling that need be extra, and this is not a big problem.To this mode, there are following two kinds of implementation methods:
Mode 1: before Scell activates, send PDCCH order signaling, promptly send activation MAC CE (Media Access Control Control Element, media access control layer control signaling) and send PDCCH order signaling before in the base station;
Mode 2: after Scell activates, send PDCCH order signaling, promptly after sending activation MAC CE signaling, send PDCCH order signaling.
Summary of the invention
For adopting PDCCH to trigger in above-mentioned two modes of PRACH process, the major defect of mode 1 is:
Shortcoming one: UE need attempt receiving the PDCCH order signaling of Scell of configuration of making a fresh start, and this is unallowed in present standard criterion, and causes extra power consumption.Its reason is: after Scell was configured, UE need begin to detect the PDCCH order signaling that perhaps is directed against this Scell from the PDCCH order signaling of Scell, until receiving this PDCCH order signaling.Make the RF front end of Scell have to be in state of activation like this until eNB triggering PDCCH order signaling.If eNB does not plan to use the Scell of this configuration in a short time, can consume the power of UE like this.(this can not include a shortcoming striding under the situation that carrier dispatching is allowed to of PDCCH order signaling, but present standard does not allow this point, and UE will abandon any PDCCH signaling of pointing to non-activation Scell in standard at present);
Shortcoming two: some Scell can be in up lock-out state (that is, be in a transient state, but Scell is configured un-activation and up lock-out in this transient state) in a period of time.If exist a plurality of timings to shift to an earlier date timer, so this situation may be commonplace;
Shortcoming three: need extra PDCCH signaling reshuffle (RRC Reconfiguration) process at RRC after.
For mode 2, UE need wait for PDCCH order signaling after receiving MAC CE activation signaling, after receiving PDCCH order signaling, correspondingly carry out time unifying more then.To this mode, also there are some misgivings:
Misgivings one: subscriber equipment can't be obeyed the operation that the defined Scell of being used for of present R10 activates, and in the operation of existing R10, UE must begin to carry out up transmission afterwards 8ms (also promptly waiting for 8 sub-frame).Reason is that after receiving activation MAC CE, UE must wait for extra PDCCH order signaling to trigger PRACH, and after this, UE could begin normal up transmission.
Misgivings two: received PDCCH order signaling is redundant downlink signaling fully after receiving activation MAC CE signaling.Reason is that according to this MAC CE signaling, this UE has known that eNB wants to dispatch this Scell, does not need further to notify through PDCCH order signaling.
According to a first aspect of the invention; A kind of method that in the user terminal of cordless communication network, communicates is provided; Wherein, This user terminal be configured the main plot with at least one from the sub-district, this at least one first being in from the sub-district and being configured and the state of uplink synchronous not from the sub-district wherein, this method comprises: do not carry out down channel and measure.
In one embodiment, this method is further comprising the steps of: receive the media access control layer signaling from the base station, wherein, this this user terminal of media access control layer control signaling indication activates this first from the sub-district; First carry out the physical accidental access procedure at this, first to realize up time synchronized from the sub-district at this from the sub-district; This first is revised as state of activation from the sub-district.
In another embodiment, this method also comprises: judge whether to detect to this first Physical Downlink Control Channel order signaling from the sub-district; First during, carry out the physical accidental access procedure, to this when detecting this to realize uplink synchronous from the Physical Downlink Control Channel order signaling of sub-district.
In yet another embodiment, judge whether to receive from the media access control layer control signaling of base station or receive from the base station to this first Physical Downlink Control Channel order signaling from the sub-district.When receiving that this media access control layer control signaling gives first during from the sub-district to activate, first carry out the physical accidental access procedure at this, first to realize up time synchronized from the sub-district at this from the sub-district; This first is revised as state of activation from the sub-district.First during, carry out the physical accidental access procedure, when receiving to realize uplink synchronous from the Physical Downlink Control Channel order signaling of sub-district to this.

Description of drawings
Through with reference to the detailed description of being done below the advantages to non-limiting example, other features, objects and advantages of the present invention will become more obvious.
Fig. 1 shows the state transition graph according to a specific embodiment of the present invention.
Wherein, same or analogous Reference numeral is represented same or analogous steps characteristic or device/module.
Embodiment
Fig. 1 shows the state transition graph according to the user terminal of a specific embodiment of the present invention.
Below, at first the term that relates among the present invention is carried out brief account.
Be configured from the sub-district: when user terminal receive RRC from the base station connect rebulid (RRC Connection Reconfiguration message) message after, but being in from the sub-district of this user terminal is configured deactivation status.
Be activated from the sub-district: after being activated, after user terminal receives the MAC CE message from the base station, should be activated from the sub-district from the sub-district.
The present invention proposes the new Scell state of definition in R11, wherein, the state of this Scell be configured but lock-out (configured but out-of-synchronization, out-of-sync), also promptly, the state A among Fig. 1.For this state A, define following user terminal behavior:
1. in order to save power, UE is to this Scell, also promptly first from the sub-district, carries out any down-run survey.For example, user terminal does not carry out the CSI measurement.
2. user terminal will be ignored any activation instruction that relates to this from the sub-district, and not carry out the activation operation of R10 definition, and promptly UE ignores the activation state in receiving MAC CE; For example, user terminal does not carry out the corresponding reference signal received power (Reference Signal Receiving Power RSRP) measures etc.; Perhaps do not carry out reference signal (Cell Reference Signal; CRS) RSRP/RSRQ (Reference Signal Receiving Quality, Reference Signal Received Quality) measures, because the operation that defines among the R10 can be found in the prior art; Therefore, do not repeat them here.In addition, because Scell does not still have up time unifying, so UE does not carry out up transmission yet behind 8ms (8 sub-frame yet promptly).
Option A: on the basis that has defined new state A, MAC CE is used for the Scell triggered time alignment procedure that is in this new state A, being described below of this process:
At first, in step S20, when user terminal receives a MAC CE; This MAC CE is used for activating and has disposed but during nonsynchronous Scell, user terminal will be automatically triggered time alignment procedure at first, also be; Carry out the physical accidental access procedure, to reach up time unifying;
After this time unifying process was accomplished smoothly, in step S21, user terminal directly was converted to state of activation with Scell, also promptly, the state D shown in Fig. 1, this is to want to dispatch this Scell now because user terminal is known the base station;
Then, in step S22, user terminal begins to carry out normal activation manipulation immediately, and does not wait for the extra 8ms time.
In another embodiment, if in step S20 ', when user terminal receives a MAC CE; This MAC CE is used for that deexcitation has been disposed but during nonsynchronous Scell; User terminal is ignored the indication of this deexcitation, and also promptly, the RSRP/RSRQ that does not carry out reference signal measures.
This new solution for the present invention proposes has following advantages:
UE needn't detect the PDCCH order signaling for Scell before receiving activation instruction, thereby had saved UE power;
Because this new state definition, UE can not run counter to the activity operations principle of R10 definition;
Need not be used for the extra PDCCH order signaling that time unifying triggers, shorten delay;
Scell directly is converted to state of activation after time unifying, has shortened the delay that is used for really up/downstream operation.
In Fig. 1, can find out, also pass through state C from state A to state D, still, this state C is a transient state, and this state C is used to trigger at this physical accidental access procedure from the sub-district, and therefore, this state C can ignore.
Option b: on the basis that has defined new state A, PDCCH order signaling can at first be sent to user terminal in the base station, and then sends MAC CE to user terminal.Then correspondingly, user terminal at first received the PDCCH order signaling from the base station before receiving MAC CE, to be used for synchronous being somebody's turn to do from the sub-district.User terminal is received the MAC CE from the base station again after receiving this PDCCH order signaling.Perhaps, if the base station before sending PDCCH order signaling, needs to send MAC CE, then the base station must be set to deactivation status to this first information from the sub-district in this MAC CE.
It will be understood by those skilled in the art that the base station can know user terminal at the state from the sub-district, comprise that this user terminal is configuration, that activate or deexcitation on this sub-district, is uplink synchronous or up lock-out.Because when during by initial configuration (configure), should must being deexcitation (deactivated) from the sub-district from the sub-district.If user terminal has completed successfully random access procedure at this from the sub-district, then user terminal is uplink synchronous at this from the sub-district, otherwise user terminal is exactly up lock-out from the sub-district at this.
The base station can be at this sends PDCCH order signaling on the Scell of state A; Perhaps activate and send the Physical Downlink Control Channel order signaling of pointing to this Scell in the sub-district at other; For example; (Carrier Indication Field CIF) points to the Scell that this is in state A in carrier wave indication territory in this PDCCH signaling.
Still with reference to Fig. 1.At first, in step S30, user terminal should detect PDCCH order signaling on this Scell, perhaps on the sub-district of other activation, detects this PDCCH signaling.After user terminal receives a PDCCH order signaling; This PDCCH is used for this Scell triggered time alignment procedure synchronously, also promptly, carries out the physical accidental access procedure; To reach up time unifying; The user terminal B that gets the hang of then, user terminal is configured and uplink synchronous, but deexcitation (deactivated);
After this time unifying process is accomplished smoothly; In step S31; User terminal receives the MAC CE from the base station, then according to the MAC CE of this reception, user terminal with the Scell state-transition to state of activation; Also be state D, this is to want to dispatch this Scell now because user terminal is known the base station;
Then, in step S22, user terminal begins to carry out normal activation manipulation immediately.
Scheme C: on the basis that has defined new state A, user terminal at first detects PDCCH order signaling or at first receives MAC CE information, can trigger user terminal respectively and get into different state.
Like the such scheme category-B, the base station can be at this sends PDCCH order signaling on the Scell of state A, perhaps activate at other and send the PDCCH order signaling of pointing to this Scell in sub-districts.
Still with reference to Fig. 1.At first, in step S40, user terminal detects PDCCH order signaling, and waits for MAC CE information.
After if user terminal at first receives a PDCCH order signaling; This PDCCH is used to trigger this Scell time unifying process, also promptly, carries out the physical accidental access procedure; To reach up time unifying; The user terminal B that gets the hang of then, user terminal is configured and uplink synchronous, but deexcitation (deactivated);
User terminal should this deexcitation from cell detection PDCCH order signaling; This PDCCH signaling of detection that is perhaps activating from the sub-district; And the carrier wave in this PDCCH signaling indication territory (Carrier Indication Field, CIF) point to this deexcitation from the sub-district.
After this time unifying process was accomplished smoothly, then, user terminal received the MAC CE from the base station; Then according to the MAC CE of this reception; User terminal to state of activation, also is state D with the Scell state-transition, and this is to want to dispatch this Scell now because user terminal is known the base station.
If user terminal at first receives a MAC CE, this MAC CE is used for activating and has disposed but during nonsynchronous Scell, user terminal will be automatically triggered time alignment procedure at first, also promptly, carry out the physical accidental access procedure, to reach up time unifying;
After this time unifying process was accomplished smoothly, user terminal directly was converted to state of activation with Scell, and this is to want to dispatch this Scell now because user terminal is known the base station;
Then, user terminal begins to carry out normal activation manipulation immediately, and does not wait for the extra 8ms time.
The those skilled in the art in those present technique fields can be through research specification, disclosed content and accompanying drawing and appending claims, and understanding and enforcement are to other changes of the execution mode of disclosure.In claim, word " comprises " element and the step of not getting rid of other, and wording " one " is not got rid of plural number.In the practical application of invention, the function of a plurality of technical characterictics of being quoted during a part possibility enforcement of rights requires.Any Reference numeral in the claim should not be construed as the restriction to scope.
