Problems solved by technology

[0004] In the edge area of ​​the LTE system, using the TTI bonding technology of the above-mentioned prior art, the TTI contained in each bonding process is limited, resulting in a relatively high packet error rate of the eNB receiving data packets. Therefore, it is urgent to provide a more efficient High transmission method to reduce the packet error rate of UE to eNB transmission data packets and enhance uplink coverage

Abstract

Provided in an embodiment of the present invention are a data packet transmission method and system, user equipment (UE) and eNB, the method comprising: the UE receives the process configuration message of a first process transmitted by the eNB; according to the process configuration message, bundling the first process with at least one second process; and transmitting the same data packet on the first process and the at least one second process. The technical solution employed in the embodiment of the present invention increases the processes transmitting the same data packet, reduces the block error rate of an eNB during uplink data packet reception, and further enhances uplink coverage especially in the edge area of an LTE system by reducing the block error rate of the uplink data packet.

Description

technical field [0001] Embodiments of the present invention relate to the field of communication technologies, and in particular, to a data packet transmission method and system, user equipment, and a base station. Background technique [0002] In the deployment of Long Term Evolution (LTE) network, in order to save costs and make network deployment more convenient, operators hope that LTE can be shared with the existing Universal Mobile Telecommunications System (UMTS) system. site, which requires LTE to achieve the same coverage as UMTS, especially uplink coverage. [0003] In order to ensure uplink coverage and improve uplink data transmission efficiency, a Transmission Time Interval (Transmission Time Interval; TTI) bundling technology was proposed in an early version of LTE. TTI is a unit of time. The main idea of ​​TTI binding is: for example, taking Voice over Internet Protocol (VoIP) data packets as an example, one VoIP data packet is regarded as a single Protocol ...
