Embodiment 1

[0086] In this embodiment, different E-RUCCH formats correspond to different SYNC-UL sequences, and the NodeB can determine the E-RUCCH format adopted by the UE according to the SYNC-UL sequence sent by the UE, and analyze the SI information reported by the UE based on this.

[0087] figure 1 It is a specific flow chart of the data transmission method on the E-RUCCH in Embodiment 1 of the present invention. Such as figure 1 As shown, the method includes:

[0088] Step 101, preset the E-RUCCH format of the single-carrier HSUPA UE and the E-RUCCH format of the multi-carrier HSUPA UE, and allocate a corresponding SYNC-UL sequence for each E-RUCCH format.

[0089] Wherein, the E-RUCCH format of the single-carrier HSUPA UE is the same as the existing format, that is, it includes 23 bits of SI information. The E-RUCCH format of the multi-carrier HSUPA UE is different from the existing format. The SI information includes the SNPL and UPH information of each HSUPA carrier supported...

Embodiment 2

[0141] In this embodiment, different E-RUCCH formats do not need to correspond to different SYNC-UL sequences, and E-RUCCH access based on NodeB blind detection is performed.

[0142] figure 2 It is a specific flow chart of the data transmission method on the E-RUCCH in Embodiment 2 of the present invention. Such as figure 2 As shown, the method includes:

[0143] Step 201, pre-set the E-RUCCH format of the single-carrier HSUPA UE and the E-RUCCH format of the multi-carrier HSUPA UE, and determine one format from the set E-RUCCH formats as a reference E-RUCCH format.

[0144] The setting of the E-RUCCH format in this step is the same as step 101 in the first embodiment, so it will not be repeated here. However, in this embodiment, since the NodeB blind detection-based E-RUCCH access is performed, the set E-RUCCH format does not need to correspond to the SYNC-UL sequence. Therefore, the number of set E-RUCCH formats is not limited by the number of SYNC-UL sequences used f...

Abstract

The invention discloses an E-RUCCH (Enhanced-Random-Access Uplink Control Channel) data transmission method in a multi-carrier HSUPA (High Speed Uplink Packet Access) system, which comprises the following steps: setting different E-RUCCH formats respectively for single-carrier HSUPA UE (User Equipment) and multi-carrier HSUPA UE; when E-RUCCH access is carried out, selecting one carrier by UE to carry out the E-RUCCH access; selecting corresponding E-RUCCH formats according to the number of HSUPA carriers supported by the UE so as to organize SI (System Information); initiating the E-RUCCH access by using one SYNC-UL (Synchronous Code-Uplink) sequence; determining expected received power by a Node B according to the E-RUCCH format selected by the UE, or determining the expected received power of a reference E-RUCCH format under a blind detection state, and feeding the expected received power to the UE; and determining the transmitting power of the corresponding E-RUCCH format by the UE according to the expected received power, and then, encoding and processing the organized SI, and sending the processed SI to the Node B through E-RUCCH. By means of the method disclosed by the invention, the SI report of the UE in the multi-carrier HSUPA system can be realized and the compatibility with the single-carrier HSUPA UE can be realized.

Description

technical field [0001] The invention relates to a data transmission method in a multi-carrier high-speed uplink packet access (HSUPA) system, in particular to a data transmission method for an enhanced dedicated channel random access uplink control channel (E-RUCCH) in a multi-carrier HSUPA system. Background technique [0002] In the HSUPA system, the network divides the 8 SYNC-UL sequences of the cell into two groups, each group includes four SYNC-UL sequences, and these two groups of SYNC-UL sequences are used for UE random access and E-RUCCH access respectively . [0003] In the implementation method of single-carrier HSUPA, the process of UE performing uplink access through E-RUCCH includes: [0004] Step 1: The UE selects a SYNC-UL from a group of SYNC-ULs used for E-RUCCH access, and sends the selected SYNC-UL to the NodeB through the HSUPA carrier where the UE is located, and initiates the uplink E-RUCCH access; [0005] Step 2, the NodeB determines the expected r...
