Description
Technical field
The present invention relates to mobile communication field more particularly to a kind of message flow sending method and devices.
Background technique
Work of OSI (OpenSystemInterconnect, the open system interconnection) model of standard network communication
It is divided into 7 layers, is physical layer (i.e. layer one, referred to as " L1 "), data link layer, network layer, transport layer, session layer, expression layer respectively
And application layer.Wherein data link layer includes: LLC (LogicalLinksControl, logic link control) positioned at upper layer
Layer, and positioned at MAC (MediaAccessControl media access control) sublayer of lower layer.Wherein media access control sublayer is mainly responsible for control
The physical medium made and connect physical layer, when sending data, media access control sublayer can judge whether that number can be sent in advance
According to if can send finally will be sent out data and control information with defined format to data plus some control information
It is sent to physical layer.
In mobile communication field, HARQ (HybridAutomaticRepeatRequest, hybrid automatic repeat-request) skill
Art is a kind of indispensable key technology, combines ARQ (AutomaticRepeatRequest, automatic repeat request) skill
The transmission mechanism of art and FEC (ForwardErrorCorrection, forward error correction coding) technology can compensate well for wireless
The influence that mobile channel time-varying and multipath fading transmit signal, the basic principle is that: the code that transmitting terminal is sent can not only be examined
Mistake, but also there is certain error correcting capability, receiving end decoder carries out error checking after receiving code word first, if in code
Within error correcting capability, then it is automatically performed error correction, if there are many mistake, has been more than the error correcting capability of code, but can detected, has then connect
Receiving end gives transmitting terminal one decision signal by feedback channel, it is desirable that transmitting terminal retransmission data packet.In such as TD-SCDMA
(TimeDivision-SynchronizationCodeDivisionMultipleAccess, Time Division-Synchronous Code Division Multiple Access are deposited
Take), WCDMA (WidebandCodeDivisionMultipleAccess, wideband code division multiple access), LTE
The mobile communication system such as (LongTermEvolution, long term evolution) or LTE-A (LTE-Advanced, senior long term evolution)
In, when using HARQ retransmission mechanism, the course of work of the transmitting terminal when sending message flow, between physical layer and media access control sublayer
Substantially are as follows:, will be on each logic channel after media access control sublayer receives the data on all logic channels according to message flow processing requirement
PDU (ProtocolDataUnit, protocol Data Unit) be assembled into MACPDU, and fill MAC header, then will be assembled
MACPDU is sent to physical layer, carries out subsequent channel transmission according to protocol requirement by physical layer and handles.If sending data to go out
When now retransmitting, by physical layer feedback decoding result to media access control sublayer, media access control sublayer will be again started up a group packet procedures, again will be multiple
MAC SDU (ServiceDataUnit, service data unit) data packet or the control unit of multiple MAC are assembled into one
MACPDU packet carries out subsequent channel transmission according still further to protocol requirement by physical layer and handles to physical layer.
From the process scheduling mechanism between above-mentioned physical layer and media access control sublayer it can be seen that physical layer and media access control sublayer are mutually handed over
Mutually realize that media access control sublayer requires a great deal of time to be wrapped in group when sending or retransmitting, what this directly increased high-rise group packet is
System expense, reduces the treatment effeciency of system, in the case of data volume is bigger, may cause and be unable to satisfy data timeliness
