Embodiment Construction

[0033] The present invention mainly comprises:

[0034] 1. A MAC-i entity is set for each group of public E-DCH resources in the Node B;

[0035] 2. Transmit public E-DCH resource information to CRNC through the Iub port public MAC flow itself or the data frame on the public MAC flow;

[0036] 3. A MAC-is entity is set for each group of public E-DCH resources in CRNC; or only one MAC-is entity is set, and a corresponding reordering unit is allocated for each group of E-DCH resources; CRNC utilizes E-DCH resource information to The received data corresponds to the appropriate MAC-is entity or reordering unit.

[0037] Among them, the specific method in 2 is: set a separate common MAC flow for each group of common E-DCH resources at the Iub port; or share one or more common MAC flows with the common E-DCH resources, and send E-DCH on the common MAC flows The data frame includes public resource indication information, and the public resource indication information is a common r...

Abstract

The invention discloses a MAC entity allocation method in CCCH signalling transmission, including that a MAC-i entity is arranged for each public E-DCH resource group in Node B; wherein the MAC-i entity transmits public E-DCH resource information in flow direction from public MAC to CRNC by Iub port. The invention also discloses a MAC entity allocation device in CCCH signalling transmission. The invention solves the problem that MAC-i and MAC-is can not operate co-ordinately and normally in CCCH transmission and is simple and practical.

Description

technical field [0001] The present invention relates to the field of wireless communication, in particular to how to allocate MAC (media channel) when transmitting CCCH (common control channel) signaling on E-DCH (enhanced-dedicated transport channel) under the CELL_FACH (cell_forward access channel) state. access control) entity. Background technique [0002] 3GPP (Third Generation Mobile Communications Partnership) is currently working on the standardization of uplink enhancement in the CELL_FACH state. CELL_FACH uplink enhancement introduces the E-DCH transmission channel in the CELL_FACH state to enhance the uplink packet data transmission performance in this state, so that it can obtain smaller packet transmission delay and higher transmission rate. [0003] In versions before 3GPP Rel-7, E-DCH transmission is only used in the CELL_DCH (cell_dedicated channel) state, and the signaling or data on the DCCH (dedicated control channel) or DTCH (dedicated traffic channel) l...
