The method comprises the following steps of: selecting corresponding HARQ profile information of a public E-DCH (Enhanced Dedicated Channel) MAC (Media Access Control) stream from the corresponding HARQ profile information of the public E-DCH MAC stream by a terminal; and transmitting CCCH (Common Control Logical Channel) data according to the HARQ profile information by the terminal. The invention increases the receiving success ratio of signaling and data.
Description
Technical field
The present invention relates to the communications field, in particular to defining method and the device of a kind of hybrid automatic repeat-request (Hybrid Automatic Repeat Request, referred to as HARQ) profile information.
Background technology
Along with the evolution of mobile communication system, the QoS of user has become the primary goal of operator, and QoS have impact on service performance, also determines the satisfaction of user to business.The very important aspect improving QoS of customer is exactly connect and time delay during channel allocation, and can there is related frequency, the business of small data packets, therefore needs to consider how common signal channel works more effective.Such as reduce the signaling delay of 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, referred to as 3GPP) standard by introduce down high speed grouping access (HSPA) realize, and the delay issue 3GPP standard of up signaling uses enhancing dedicated channel (Enhanced Dedicated Channel, referred to as E-DCH) channel to solve under being introduced in CELL_FACH state and empty (idle) pattern.
In order to reduce up signaling delay, need to consider following several aspect:
(1) IDLE mode is reduced, the user face of CELL_FACH, Cell_PCH andURA_PCH state and the stand-by period of chain of command
(2) peak rate of CELL_FACH state is increased
(3) transition delay between idle, CELL_FACH, CELL_PCH and URA_PCH state, CELL_DCH state is reduced.
In order to achieve the above object, can introduce in Idle pattern, CELL_FACH state the mode using high speed uplink packet access high speed uplink packet access (High Speed UplinkPacket Access, referred to as HSUPA); Idle state and CELL_FACH state are used high-speed uplink packet access technique herein, be called uplink reinforced CELL-FACH technology.
