The implementation process of the embodiment of the present invention is described in detail below in conjunction with preferred embodiment.
TD-SCDMA system constitutes frame structure in units of system-frame, and system frame length is 10ms, and each system-frame is divided into
Two subframes, each subframe 5ms is equally divided into 6400 chip, and each subframe has 7 regular time slots (Time Slot, abbreviation
For TS) TS0~TS6, wherein TS0 and TS6 be fixed as descending time slot, TS1 is fixed as ascending time slot, other time slots according to up and down when
It is ascending time slot or descending time slot that gap transfer point, which is determined, and a subframe only has two uplink and downlink timeslot transfer points.In addition when
There are three special time slots between gap TS0 and time slot TS1：Descending pilot frequency time slot (Downlink Pilot Time Slot, referred to as
For DwPTS), protection interval (Guard period, referred to as GP) and uplink pilot time slot (Uplink Pilot Time
Slot, referred to as UpPTS), these three time slots are mainly used in down-going synchronous and uplink synchronous.TD-SCDMA down channel is all held
It is loaded on descending time slot.Each regular time slots include 864 chip, wherein the 144chip started at 352chip is channel
Midamble codes are used to reflect channel quality, and the 352chip before and after it is data division, and time slot tail has 16 chip interval
Area.Fig. 3 Dw into Fig. 5 represent that DwPTS, Up represent UpPTS.
Down channel reception processing is divided at software and hardware coordination by the processing of TD-SCDMA user equipment downlinks physical layer channel
Reason is completed.Wherein, parameter needed for software processing completes control flow and hardware is calculated and configured, and hardware handles complete operand ratio
Larger algorithm calculation process.Parameter needed for software is worked hardware computation by hardware configuration interface is configured at the regulation moment
To hardware, result is reported notice software by hardware after calculation process by interrupt mode, and software receives interruption and reported
Afterwards, from hardware interrupts report information interface in read needed for processing data and result.Software control flow needs to distinguish various
Downlink traffic channel receives scene, and parameter needed for the hardware of the scene is calculated and is allocated to hard in moment point as defined in hardware
Part, because various downlink business have TTI, TTI to be all the multiple of subframe in TD-SCDMA system, so taking miscellaneous service most
Small TTI is that unit carries out service parameter configuration, and the length of minimum TTI may be a subframe, so down channel handles software
Row control is carried out in units of a subframe.And down physical channel hardware interrupts, which are reported, to be carried out in units of time slot
Report, so software interrupt processing, if down channel also needs to be transmitted Channel Processing, is had in TFCI in units of time slot
Disconnected or TTI interrupt processings, it based on system-frame or TTI is unit that they, which are, and software gives the correct time in interruption, distinguishes different interruptions
Type simultaneously reads interruption associated channel parameters progress subsequent treatment.
The embodiment of the present invention mainly includes two parts：Down physical layer channel parameter configuration processing based on TTI and subframe
With timeslot-based down physical layer channel hardware Interrupt Process (TFCI interrupt or TTI interrupt be based on frame or TTI), it is right
Down physical layer channel is managed collectively, and is easy to implement and is extended.The processing of down physical layer channel configuration is mainly according to upper
Layer scheduling determines whether next TTI needs to carry out the reception of respective impact channel, carries out next TTI's in each TTI tails
Channel parameter is configured, and this configuration at the time of point must assure that hardware will not take these configuration parameters to carry out connecing for current TTI again
Receive, while also to judge whether next TTI needs to carry out the reception of down channel in this moment point, if desired receive then just
Often configuration, relevant configuration is discharged if it need not receive.Down channel hardware Interrupt Process is main in units of time slot, according to hard
The interruption that part processing procedure different phase is reported obtains corresponding parameter to be made for correlation functions such as control, measurement and synchronous power controls
With.
Wherein, above-mentioned down physical layer channel parameter configuration processing is divided into three parts, respectively descending conventional channel again
Configuration processing, descending emergency channel configuration processing and down channel release processing.The TTI settings of each down channel are as follows：Unit
For a subframe, PCCPCH be 4, PICH for 1 (PI indicate only can in a subframe, from a subframe with regard to can solve with
The PI at family is indicated), SCCPCH is configured by net side, and usually 4, FPACH is that the maximum FPACH that net side is configured receives number of sub frames, if
This subframe can be set to last subframe of TTI by receiving after the FPACH of this user, descending DPCH is configured by net side, HS-
SCCH is that 1, HS-DSCH is that 1, E-AGCH is that 1, E-HICH is 1.
Preferred embodiment one
This preferred embodiment is illustrated to down channel configuration processing.Fig. 2 is according to the preferred embodiment of the present invention one
The timing diagram of down channel configuration processing, from figure 1 it appears that down channel configuration is handled based on minimum TTI,
TTI unit is subframe.Physical layer receives scheduler module L1S (Schedule of Layer 1) and judges there are downlink traffic channel needs
During reception, it can be issued in the previous subframe in TTI borders of the downlink traffic channel to down channel receiving module RX (Receiver)
Down channel configuration request message, is typically all issued in the TS0 time slots of this subframe.When down channel receiving module is received
After the down channel configuration message that L1S is issued, preserve relevant configuration information and calculate next TTI configuration parameter, and
The hardware parameter of down channel is allocated to hardware after the time slot TS6 of this subframe 352chip, system needs that note can be supported
Volume TS6 352chip level events.It is because RX hardware acceptance down physical channel data are to select this moment point to configure hardware
In units of time slot, hardware obtains the parameter of software merit rating by hardware configuration interface at the 352chip of row time slot in each of the lower
Start working, match somebody with somebody for the parameter that all time slots of next subframe are preferably uniformly processed in the reception of sub-frame level down channel in this position
Put, but also do not influence the reception of present sub-frame time slot.Hardware after each TTI first subframe gets configuration parameter,
The down channel completed in this TTI is received, and hardware effort is stopped after hardware configuration parameter is released.In addition in order to reduce
The frequency of hardware update parameter, the parameter all similarly configured when being received for each descending time slot can update one with a subframe
Secondary, hardware selection updates these sub-frame level parameters at time slot TS0 352chip.
The release processing of down channel is the configuration that new TTI is not received before one TTI of down channel is received
Triggered during request, this judgement is placed at the 352chip events for the TS6 that a TTI receives last subframe, if this subframe
TS0 does not receive the down channel configuring request that L1S is issued, then starts release flow, removes hardware configuration parameter and software ginseng
Number, stops the work of the hardware acceptance channel；If the TS0 of this subframe have received the down channel configuring request that L1S is issued, open
Dynamic Reconfiguration Procedure, will enter hardware, but need to preserve new and old two sets for software parameters with parameter configuration again as new configuration
Parameter old configures the interruption that reports to handle.
Preferred embodiment two
In down channel, two kinds of descending conventional channel and descending emergency channel can be divided into.Descending conventional channel refers to
On TTI borders, previous subframe time slot TS0 just can judge the down channel of next TTI receptions whether in need, such as down channel
PCCPCH, PICH, SCCPCH, FPACH, descending DPCH, HS-SCCH and E-AGCH.Descending emergency channel refers to before TTI borders
One subframe time slot TS0 can not determine whether next TTI needs to receive down channel, but receive and solve in this subframe relevant information
After analysis, the down channel of next TTI receptions whether in need, such as down channel HS-DSCH and E-HICH could be determined.Due to
The different characteristics of this two classes down channel, down channel configuration processing is divided into two kinds of processing modes (at descending conventional channel configuration
Reason mode and descending emergency channel configuration processing mode), but the release processing mode of this two classes down channel is still identical.
This preferred embodiment is illustrated respectively in connection with Fig. 3 and Fig. 4 to above two configuration processing mode.
Fig. 3 is the timing diagram that processing is configured according to the descending conventional channel of the preferred embodiment of the present invention two, descending letter by ordinary
Road all carries out configuration processing using this flow.As shown in figure 3, A points are the time slot TS0 of the previous subframe in TTI borders, at A points,
Down channel receiving module RX receives the down channel configuring request that physical layer scheduling module L1S is issued, and the set descending letter
Road, which needs to configure, receives mark.During B points are the timeslot-level time processing units of TS1 (Time Process Unit, referred to as TPU)
Disconnected, configurating downlink channel receives sub-frame level parameter, is obtained once in time slot TS0 because sub-frame level parameters hardware is a subframe,
So can just receive public sub-frame level parameter to each down channel of next subframe in the time slot TS1 of the previous subframe in TTI borders
Configured, it is necessary to illustrate, the moment point can move on at time slot TS6 352chip events and timeslot-level parameter together
Configuration.C points are that registered events are interrupted at time slot TS6 352chip, and each subframe has, and RX modules are configured according to down channel
Configuration receives mark configuration hardware parameter, including physical channel hardware parameter and transmission channel hardware parameter the need for request, and
And the configured reception mark of the upper down channel is put, removing needs to configure reception mark.In the non-TS0 business of this TTI of D points
Disconnected position of coming into force earliest, and B points phase is in the same time, is the timeslot-level registered events that each subframe has, the timeslot-level place of down channel
The interruption of reason is the latest in next time slot.If down channel configuration has in TS0 in C points with regard to the processing interruption of set down channel
Valid flag, if down channel configuration after D points judge that the configured reception mark of down channel is set with, puts interruption in non-TS0
Effective marker.Down channel processing interruption effective marker, which is divided into physical channel processing, which interrupts effective marker and transmission channel interruption, has
Valid flag.
Fig. 4 is the timing diagram that processing is configured according to the descending emergency channel of the preferred embodiment of the present invention two, descending urgent letter
Road can use this flow, and receiving analysis result according to down channel could determine whether next TTI needs to receive descending letter
Road.This kind of down channel processing is divided into two kinds, and one kind is that in C points, (down channel receiving module RX matches somebody with somebody down channel configuring request
Put hardware) issue before, then identical with descending conventional channel configuration processing mode, it is to preserve and count to receive configuration request message
Parameter is calculated, then hardware configuration is carried out in C points.Another is exactly to receive down channel configuration request message after C points, at this
In the case of kind, handled according to descending emergency channel configuration handling process, i.e. configuration is hard while receiving configuration request message
Part.In Fig. 4, E points are that down channel receiving module RX receives descending emergency channel configuring request at the time of point, and E points are located at C points
Afterwards, i.e., in E points hardware parameter will be configured, and the configured reception mark of the set down channel.
Current time (at the time of receiving down channel configuring request) is compared front and rear method with C points and is exemplified below：Can
To record the subframe numbers of the subframe numbers of time slot TS1 events and time slot TS6 352chip events, at current time, if TS1 things
The subframe numbers of part are equal to the subframe numbers of TS6 events, then current time is positioned at previous subframe TS6 and next two events of subframe TS1
Between (as shown in Figure 4)；If two subframe numbers, current time is located at the TS1 events and TS6 events of current same subframe
Between.
Preferred embodiment three
The release process of down channel is described in detail this preferred embodiment.Fig. 5 is preferable to carry out according to the present invention
The timing diagram of the down channel release processing of example three, as shown in figure 5, F points, which are down channel receiving module RX, judges down channel
Point at the time of release, the moment point is identical with C points, is all at time slot TS6 352chip, to be received when the down channel is configured
When mark is put, it is necessary to judge whether down channel needs release in the subframe.
Judge that the down channel method whether to be discharged is as follows：Down channel configuration request message is received in A points or E points
When, next TTI last subframe numbers are calculated and preserve, in the time slot TS6 of current TTI last subframe
The subframe of last subframe for next TTI that more current subframe numbers and the down channel are preserved at 352chip events
Number, when the two is equal, it is determined that the down channel needs release, then set release mark, and remove the down channel
Configuration receives mark, discharges the physical channel hardware configuration processing parameter of the down channel.Because transmission channel hardware handles exist
Next subframe will also be carried out, so transmission channel hardware configuration parameter carries out hardware configuration again in next subframe according to release mark
Release, if the down channel does not need transmission channel processing, is released after physical channel configuration parameter, directly by release mark
Remove.
G points are at time slot TS1 registered events, if the down channel release mark has been put, to remove the physics letter of the channel
Effective marker is interrupted in road processing, and the release mark of the down channel is removed if being configured without transmission channel.H points are the down channels
At transmission channel processing TFCI interruptions, if TFCI is 0, the transmission channel hardware configuration parameter of the down channel is discharged, and clearly
Except effective marker and the release mark of the down channel are interrupted in transmission channel processing；If TFCI is not for 0, (i.e. the interruption has been reported
To software), then continue to configure transport channel parameters, and carry out subsequent decoding processing.I points are the downlink channel transmission Channel Processings
At TTI interruptions, after the complete interruption of software processing, the transmission channel hardware configuration parameter of the down channel is discharged, and remove transmission
Channel Processing interrupts effective marker and the release mark of the down channel.J points are the processing of down channel release guard, with C points, F
Point position is identical, if the down channel release mark has been put, and more than release time, then forces progress down channel release to be protected
Shield, prevents the reception of down channel behind hardware interrupts anomalous effects.
Preferred embodiment four
This preferred embodiment is that down channel hardware Interrupt Process process is described, in the preferred embodiment, nothing
By descending conventional channel or descending emergency channel, its interrupt processing is all identical.
Physical channel processing is interrupted in units of timeslot-level, and each time slot carries out a wheel interruption and reported, physical channel processing
Interruption has channel estimation to interrupt Mche_int, and joint-detection decoding discontinuities Jdcore_int and E-HICH decoded result are interrupted
Ehich_int.Wherein, channel estimation, which is interrupted, is reported after the complete Midamble codes relevant treatment of physical channel hardware handles, is reported
Information have the channel evaluation data and interference signal intensity of this cell；Joint-detection decoding discontinuities are to have handled sign level data
Reported after decoding, the information reported has decoding soft bit decoding data and code channel activating information；It is to have handled E- that E-HICH, which is interrupted,
Reported after HICH decodings, the information reported is E-HICH decoded informations.
