Embodiment 1

[0040] This embodiment provides a method for uplink data transmission, see figure 1 shown, including:

[0041] Step Y1: Obtain the scheduling priority indication information of each common enhanced dedicated transport channel MAC-d data flow Common E-DCH MAC-d flow or each logical channel;

[0042] Step Y2: receiving the scheduling information sent by the user equipment UE in the enhanced cell forward access channel CELL_FACH state;

[0043] Step Y3: Obtain scheduling grant information for uplink scheduling of the UE according to the scheduling priority indication information and the scheduling information;

[0044] Step Y4: Send the scheduling grant information to the UE.

[0045] Through an uplink data transmission method provided in this embodiment, the NodeB obtains the scheduling priority indication information of each logical channel, so that the NodeB can determine whether the logical channel with the highest priority of the UE is sending service data or signaling data....

Embodiment 2

[0047] This embodiment provides a method for uplink data transmission, see figure 2 shown, including:

[0048] Step 1: Node B receives the Common E-DCH MAC-d flow (Common E-DCH MAC-d flow) information that contains the Scheduling Priority Indicator information sent by the RNC;

[0049] It should be noted that, in this step, the Common E-DCH MAC-d flow information including the scheduling priority indication information may specifically be: information identifying the priority level of each Common E-DCH MAC-d flow, for example, the Common The priority level of E-DCH MAC-d flow is divided into 1 to 15 levels, 1 is the highest priority, descending in descending order, and 15 is the lowest priority. The Common E-DCH MAC-d flow information including the scheduling priority indication information may also be: information identifying a priority level of a logical channel. Wherein, multiple logical channels mapped to a Common E-DCH MAC-d flow have the same priority level, which is ...

Embodiment 3

[0066] This embodiment provides an uplink data transmission method. The difference between this method and the method provided in Embodiment 1 lies in that in Embodiment 1, the Common E-DCH MAC-d flow containing scheduling priority indication information sent by NodeB from RNC The scheduling priority indication information is acquired from the information, and in this embodiment, the NodeB can acquire the scheduling priority indication information from itself, and the scheduling priority indication information is preset in the NodeB. see Figure 5 As shown, the method includes:

[0067] Step A1: NodeB sets the scheduling priority indication information of each Common E-DCH MAC-d flow or each logical channel;

[0068] In this step, the Node B can configure scheduling priority indication information for each Common E-DCH MAC-d flow or each logical channel through an operation and maintenance (o&m) platform.

[0069]Step A2: Similar to Step 2 in Embodiment 1, the Node B receive...

Abstract

The invention discloses an uplink data transmission method comprising the following steps: obtaining each public enhanced dedicated transport channel MAC-d data stream Common E-DCH MAC-d flow or the dispatching priority indication information of each logic channel; receiving dispatching information sent by the user equipment (UE) in the state of enhanced cell forward access channel CELL-FACH; according to the dispatching priority indication information and the dispatching information, obtaining the dispatching authorization information of the uplink dispatching to UE; and sending the dispatching authorization information to UE. The embodiment of the invention also provides a corresponding device and a communication system. In the technical scheme of the invention, because the node B obtains the dispatching priority indication information, the invention can judge that the logic channel of UE sends service data or signalling data so as to send reasonable uplink dispatching information to UE, thus shortening the delay time for UE to send information data.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a method, device and communication system for uplink data transmission. Background technique [0002] In the 3rd Generation Partnership Project (3GPP, 3rd Generation Partnership Project) Universal Mobile Telecommunications System (UMTS, Universal Mobile Telecommunications System) R8 version, for the user equipment in the idle Idle state or the cell forward access channel state CELL_FACH state ( UE, User Equipment), in order to reduce the uplink transmission delay and increase the uplink transmission rate, a new feature of CELL_FACH state uplink enhancement is introduced. The CELL_FACH state uplink enhancement feature enhances the random access process of the R99 version. The enhanced random access process uses the enhanced dedicated transport channel (E-DCH, Enhanced Dedicated Transport Channel) instead of the random access channel (RACH, Random Access Channel). U...
