Description
Technical field
The present invention relates to the communications field, in particular to the definite method and the device of the automatic repeat requests of a kind of mixing (Hybrid Automatic Repeat Request abbreviates HARQ as) profile information.
Background technology
Along with the evolution of mobile communication system, user's QoS has become the primary goal of operator, and QoS has influenced service performance, has also determined the satisfaction of user to business.A very important aspect that improves QoS of customer is exactly to connect and the time delay during channel allocation, and can exist frequent relatively, the business of small data packets, it is more effective therefore to need to consider how common signal channel works.Such as the signaling delay that reduces up link and down link.CELL_FACH, downlink signaling delay control third generation partnership project (the 3rd GenerationPartnership Project of CELL_PCH/URA_PCH state, abbreviating 3GPP as) standard inserts (HSPA) and realizes by introducing the down high speed grouping, and the delay issue 3GPP standard of up signaling uses enhancing dedicated channel (Enhanced Dedicated Channel abbreviates E-DCH as) channel to solve by being introduced under CELL_FACH state and sky (idle) pattern.
In order to reduce up signaling delay, need to consider following several aspects:
(1) reduces IDLE mode, CELL_FACH, the user's face of Cell_PCH andURA_PCH state and the stand-by period of chain of command
(2) peak rate of increase CELL_FACH state
(3) reduce transition delay between idle, CELL_FACH, CELL_PCH and URA_PCH state, the CELL_DCH state.
In order to achieve the above object, can introduce the mode of using high speed uplink packet to insert high speed uplink packet access (High Speed UplinkPacket Access abbreviates HSUPA as) at Idle pattern, CELL_FACH state; This paper uses high-speed uplink packet access technique to Idle state and CELL_FACH state, is called the uplink reinforced CELL-FACH technology.
The basic principle of uplink reinforced CELL-FACH technology is as follows: the transmission principle of Jie Ruing still adopts Physical Random Access Channel (Physical Random AccessChannel at random, abbreviate PRACH as) random access procedure, but change has taken place in channel type, also promptly can use reinforcement dedicated channel E-DCH in idle pattern and CELL_FACH state, public control logic channel (Common Control Logical Channel, abbreviate CCCH as)/Dedicated Control Channel (Dedicated Control Channel, abbreviating DCCH/ Dedicated Traffic Channel (Dedicated Traffic Channel abbreviates DTCH as) logic channel as can be mapped on the E-DCH and send.
The Uu mouth of 3GPP agreement has defined idle state and the employed common E-DCH medium of CELL_FACH state access control (Media Access Control at present, abbreviate MAC as) stream, the information that this MAC stream comprises is: the power deviation of E-DCH MAC stream, maximum retransmission, and whether the PDU between the different MAC stream is among reusable to the MAC-i PDU.
As subscriber equipment (User Equipment, abbreviate UE as) during data on sending E-DCH, which then at first need to be mapped to MAC stream according to logic channel, and then definite power deviation that sends the employed E-DCH MAC stream of these data, the maximum retransmission of E-DCHMAC stream, multiplexing indication (indicating which MAC-d flow in a TTI, to be multiplexed among the MAC-i PDU) between the different E-DCH MAC streams.
Yet in system broadcast message, do not broadcast the Different Logic channel Mapping in the agreement to which common E-DCH MAC stream, mapping relations for DCCH/DTCH logic channel and common E-DCH MAC stream can be notified in RB mapping info, but use not have signaling in which HARQ profile information 3GPP standard agreement for the CCCH logic channel, clearly do not stipulate the HARQ profile information that UE uses for CCCH yet, therefore when UE need send the CCCH logical channel information on E-DCH, to not know how to determine that it shines upon the transmitting power of E-DPDCH, thereby it is inconsistent can causing UE and the employed HARQ profile of (Node B) Node B information, thereby causes decoding error.
