Problems solved by technology

[0004] The DC-HSUPA technology has the following technical defects in actual operation: when the terminal is at the edge of the network coverage of the sector, the uplink transmission rate may be affected due to the poor signal quality of the carrier providing the service; Due to the limited transmission power of the terminal, the dual-carrier working mode cannot be used; and if the load of the carrier is heavy, this technology will basically not bring additional system gain

Embodiment 1

[0037] figure 1 It is a schematic flow chart of Embodiment 1 of the uplink data transmission method of the present invention. The method of this embodiment can be executed by a terminal, and the terminal of this embodiment has a multi-carrier working capability. Such as figure 1 As shown, the method may include the following steps:

[0038] Step 101, the terminal sends a carrier measurement report message to the network side device, and the carrier measurement report message includes the signal quality of each carrier in multiple sectors where it is located;

[0039] The terminal is in the overlapping coverage area of ​​multiple sectors, and selects one of the cells to camp on according to the existing cell selection or reselection mechanism. Wherein, the multiple sectors may be multiple sectors belonging to the same base station, or may also be multiple sectors respectively belonging to different base stations;

[0040] The terminal can search for all carrier resources in ...

Embodiment 2

[0046] figure 2 It is a schematic flowchart of Embodiment 2 of the uplink data transmission method of the present invention. The method of this embodiment can be executed by a network side device such as a base station, such as figure 2 As shown, the method may include the following steps:

[0047] Step 201, the network side device receives the carrier measurement report message sent by the terminal, and the carrier measurement report message includes the signal quality of each carrier in multiple sectors where the terminal is located;

[0048] Step 202, the network side device selects multiple serving carriers from the carriers according to the signal quality and load information of the carriers;

[0049] The load information of each carrier is obtained by the network side equipment. For example, when each carrier belongs to the same base station, the base station can obtain the load information of each carrier in all sectors; when each carrier belongs to different base st...

Embodiment 3

[0061] image 3 It is a schematic flow chart of Embodiment 3 of the uplink data transmission method of the present invention. In this embodiment, the technical solutions of the present invention described in Embodiments 1 and 2 are described in more detail, as shown in image 3 As shown, the method may include the following steps:

[0062] Step 301, the terminal is in the overlapping coverage area of ​​multiple sectors and resides in a certain cell;

[0063] see Figure 4 as shown, Figure 4 It is a schematic diagram of terminal positions in Embodiment 3 of the uplink data transmission method of the present invention. Should Figure 4 Take the overlapping coverage of three sectors as an example.

[0064] Wherein, the three sectors include sector 1, sector 2 and sector 3, sector 1 is configured with FA carriers, sector 2 is configured with FB carriers, and sector 3 is configured with FC carriers. A terminal capable of uplink multi-carrier transmission is located in the ov...

Abstract

The present invention provides an uplink data transmission method, device and system, wherein the method includes: sending a carrier measurement report message to the network side equipment, the carrier measurement report message includes the signal quality of each carrier in multiple sectors; receiving The activation control instruction sent by the network-side device, and according to the activation control instruction, uplink transmits data to the network-side device through the service carrier in at least two sectors; the service carrier is the network-side device according to the The load information and signal quality of each carrier described above are determined. The invention solves the problem that the traditional uplink dual-carrier technology cannot be used normally due to limited terminal power at the coverage edge, and further improves the utilization rate of system wireless resources and the uplink transmission rate of edge users.

Description

technical field [0001] The present invention relates to communication technology, in particular to an uplink data transmission method, device and system. Background technique [0002] With the rapid development of information technology, various novel network applications emerge in an endless stream, such as high-definition video calls, high-definition online video, etc. At the same time, people's demand for better mobile communication services anytime and anywhere is increasing. In order to meet the requirements for the development of broadband mobile communications in the future, the 3rd Generation Partnership Project (3rd Generation Partnership Project, referred to as: 3GPP) has introduced multi-carrier technology, in which high speed uplink packet access (high speed uplink packet access, referred to as: On the basis of HSUPA), dual-carrier HSUPA (abbreviation: DC-HSUPA) is further introduced. [0003] DC-HSUPA technology is an important technology to improve the uplink ...
