Problems solved by technology

Obviously, this method makes it impossible for the base station to determine which UE sent the received data, resulting in the inability to transmit information between the UE and the base station, and in turn causing the base station to fail to send the information uploaded by the UE to a control such as RNC. equipment

Embodiment 1

[0025] The UE adds a UE ID to each layer 2 data packet reported to the NodeB. When the NodeB receives each layer 2 data packet, it can determine which UE the data packet is based on the UE ID carried in the data packet. Reported. Among them, the layer 2 is the protocol layer of the air interface, including a variety of protocols, usually including medium access control (MAC, Medium Access Control) protocol, radio link control (RLC, Radio Link Control) protocol and packet data convergence protocol (PDCP, Packet Data Convergence Protocol), etc.

[0026] This embodiment can ensure that the NodeB confirms which UE each layer 2 data packet sent on the E-DCH transmission bearer channel corresponds to, and the specific implementation is very simple.

Embodiment 2

[0028] The specific implementation process of this embodiment is as follows: figure 1 As shown, corresponding to the following steps:

[0029] Step 101, UE carries UE ID in the first information reported to NodeB.

[0030] Before uplink access, the UE first obtains initial resources through competition. In the embodiment of the present invention, the uplink of the UE uses the HSUPA technology, and correspondingly, the obtained initial resource is the E-DCH transmission bearer channel. The first information reported by the UE to the NodeB also needs to be reported through the E-DCH transmission bearer channel. In this embodiment, the UEID is further carried in the first information. In addition, although the E-DCH transmission bearer channel is used as a shared channel in the embodiment of the present invention, after the UE obtains the channel resource through competition, it will also use the resource to send uplink data for a period of time.

[0031] For the UE, the MAC-e...

Abstract

The embodiment mode of the invention provides a method for realizing information transmission. The method comprises the following steps of a base station receives information transmitted, borne and reported via an enhanced dedicated channel (E-DCH) by user equipment (UE); and according to the UE identification information carried by the received information, determining UE corresponding to the information received by the base station. The embodiment mode of the invention also provides a system and a base station for realizing information transmission. According to the embodiment of the invention, the purpose that the base station can determine which UE sends the data while receiving the data when high speed uplink packet access (HSUPA) is used for transmitting random access data between the UE and the base station is realized, and therefore, a transmission scheme that the HSUPA is used for realizing random access is guaranteed to be implemented.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular to a method, device and system for realizing information transmission. Background technique [0002] In a wireless communication system, it is necessary to exchange uplink and downlink information to realize wireless communication between a base station and a user equipment (UE). [0003] In order to enhance the data transmission rate, the industry has proposed a processing scheme of using HSDPA in the downlink common channel, so that the downlink transmission rate can reach 100Kbps in theory. But the downlink transmission rate is also affected by the uplink transmission rate. For example, the current uplink transmission mainly adopts the method of sharing a random access channel (RACH, Random Access Channel), which leads to a slow uplink response, which in turn affects the downlink transmission rate. [0004] In order to solve this problem, the industry cur...
