Abstract
The invention provides an in-synchronization and out-of-synchronization detection method, which detects downlink in-synchronization and out-of-synchronization by using a high-speed shared control channel (HS-SCCH), an enhanced-absolute grant channel (E-AGCH), a high-speed physical downlink shared channel (HS-PDSCH) and an enhanced hybrid indicator channel (E-HICH) in the downlink channels for a transmission/scheduling mode in an HSPA+ and detects the downlink in-synchronization and out-of-synchronization by using an enhanced physical uplink channel (E-PUCH) and a high-speed shared information channel (HS-SICH) in uplink channels or by a stand alone midamble channel. Thus, when user equipment (UE) temporarily has no data block transmission with cyclic redundancy check (CRC) in the uplink/downlink direction, the corresponding in-synchronization and out-of-synchronization detection can be completed by using the E-HICH, E-PUCH and HS-SICH or the stand alone midamble channel, and the accuracy of the in-synchronization and out-of-synchronization detection on a wireless link of the UE is improved.
Description
Technical field
The present invention relates to signal detection technique, when particularly relating to a kind of nothing and following channel synchronously and the detection method of step-out.
Background technology
In the TD-SCDMA system, carry out under the high speed/during upstream data service (HSPDA/HSUPA) transmission, can dispose/descending following special physical channel (DPCH) with on auxiliary/down-going synchronous and detection of loss of mains.Synchronous detecting is called In-Sync, and detection of loss of mains is called Out-of-sync.The receiving terminal physical layer is regularly reported Out-of-sync to high level report In-sync or with CPHY-Out-of-Sync-IND primitive to high level with CPHY-Sync-IND primitive, after receiving some Out-of-sync continuously, receiving terminal is thought this Radio Link Failure, and this Radio Link Failure of notice transmitting terminal.
Follow the signal strength signal intensity of signal strength signal intensity, special burst of DPCH and the transmission block that has a CRC (CRC) whether to transmit correct these three conditions by detection in the existing protocol and carry out judgement with/step-out.Specific as follows:
(1) the synchronization decisions condition of down direction:
If any one in the following condition is met, then subscriber equipment (UE) physical layer need be reported In-sync with CPHY-Sync-IND primitive:
Condition one, UE estimate dedicated channel burst quality in the end 160ms be higher than a threshold value Qin in the cycle.Qin is a preset value.
Condition two, interim when last 160ms, UE detects the special burst that at least one quality is higher than threshold value Qsbin.Qsbin is a preset value.
Condition three, in a TTI, have at least a transport module that has a CRC in present frame with correct CRC ending.
(2) the step-out determining condition of down direction:
If following three conditions are met simultaneously, then need with CPHY-Out-of-Sync-IND primitive report Out-of-sync:
Condition one, UE estimate dedicated channel burst quality in the end 160ms be lower than a threshold value Qout in the cycle.Numerical value Qout is a preset value.
Condition two, interim when last 160ms does not detect the special burst that any quality is higher than threshold value Qsbout.Numerical value Qsbout is a preset value.
Condition three, in preceding 160ms, do not receive any transport module that has correct CRC.
(3) up with/step-out determining condition:
The layer 1 of Node B need be checked synchronous regime to each uplink merging channel (ULCCTrCH) of Radio Link in each radio frames.According to concrete check result, utilize CPHY-Sync-IND or CPHY-Out-of-Sync-IND primitive to indicate and trigger function to Radio Link Failure/reparation.Node B can adopt similar for example based on the method that receives burst quality or crc check.Example is that the condition that adopts is identical with down-going synchronous state primitive.
(HSDPA/HSUPA in the enhancement techniques high-speed data packets access enhanced technique (HSPA+) HSPA), for improving throughput of system and number of users, has cancelled special burst and has followed DPCH and insert in high-speed data packets.Whether UE and base station (Node B) can only transmit correct this rule by the transmission block that has CRC is carried out the judgement of same/step-out, like this, when on certain UE/when descending temporary nothing has the transmission of data blocks of CRC, the condition of its descending step-out will be satisfied, promptly in preceding 160ms, do not receive any transport module that has correct CRC, therefore, just might cause the erroneous judgement of down wireless link step-out according to above-mentioned rule.
This shows that after having introduced HSPA+ in the system, existing detection method synchronous and step-out will be no longer healthy and strong, promptly can't carry out exactly together/detection of loss of mains.And the HSPA+ that does not propose a kind of optimization at present as yet is synchronous and the detection method of step-out.

Embodiment
For making the purpose, technical solutions and advantages of the present invention clearer, the present invention is described in further detail below in conjunction with specific embodiment.
Main thought of the present invention is: to utilize the channel that is used for dynamic dispatching in the HSPA+ up-downgoing transmission be HS-PDSCH and E-PUCH with and control channel HS-SCCH, HS-SICH, E-AGCH and E-HICH carry out the uplink and downlink direction synchronously or detection of loss of mains.Particularly, at down direction, it is fast that HS-SCCH in the down channel, E-AGCH and HS-PDSCH have the CRC transmission, then there is the signature sequence behind the particular UE secondary spread spectrum on the E-HICH, this signature sequence is the secondary spread-spectrum sequence of carrying out SF=80 at a SF=16 code channel, therefore, when there is not the CRC transmission block at down direction only during collocating uplink half-persistence scheduling resources (SPS), can whether surpass by the signal strength signal intensity of the signature sequence among the pairing descending E-HICH of up E-PUCH that judges UE a threshold value as descending with/mistake decision rule; At up direction, when not having the CRC transmission block at up direction, the burst quality of intermediate code channel (Stand alone midamble) that can be by detecting the independent transmission that HSPA+ newly adds and/or the quality of HS-SICH and/or E-PUCH realize up synchronous/asynchronous detection, like this, when on the uplink and downlink direction, not having the CRC transmission block, still can carry out synchronous and detection of loss of mains exactly, thereby can detect current channel synchronization and desynchronizing state exactly.Specific implementation method below by a pair of above-mentioned thought of the embodiment of the invention describes.

In UE was known Preset Time after its down link has been set up, the physical layer of UE was monitored its down channel situation, if described monitoring result satisfies at least one in the set of down-going synchronous testing conditions, then the high level to UE sends synchronous indication information;
After UE is known described Preset Time after down link has been set up, the physical layer of UE is monitored its down channel situation, if described monitoring result satisfies at least one in the set of down-going synchronous testing conditions, then the physical layer of this UE sends synchronous indication information to the high level report of UE; If the channel conditions of this UE satisfies all conditions in the default descending detection of loss of mains set of circumstances simultaneously, then the physical layer of this UE sends the step-out indication information to the high level report of UE.
In the said process, at down direction, divide two stages to carry out the detection of same/step-out, phase I is that UE was known in initial a period of time that its down link set up, promptly know that with UE its down link has been established as in one section described Preset Time of initial point, second stage is the time after the phase I, and promptly UE is known after the described Preset Time of down link after having set up; In the phase I, for the existing protocol compatibility, the physical layer of UE can not be Out-of-sync to the high level of UE report step-out, and can only report to be In-Sync synchronously, therefore only need carry out synchronous detection to get final product; And in second stage synchronously and step-out all need report, therefore need carry out relevant detection to synchronous and step-out simultaneously.

Like this, when collocating uplink SPS, during promptly descending no CRC transmission block, can whether surpass threshold value QEin, judge certainly down-going synchronous or step-out by the signal strength signal intensity of the signature sequence among the E-HICH that judges the E-PUCH correspondence.
