Embodiment Construction

[0041] The inventor found in the process of implementing the present invention that: current smart phones usually not only support short-distance communication technologies such as WiFi or Bluetooth (BlueTooth), but also support long-term evolution (Long Term Evolution, LTE for short), Universal Mobile Communication System (Universal Mobile Telecommunications System, referred to as UMTS), CDMA, GSM or WiMAX and other cellular communication technologies. In the scenario of cooperative communication between a single network node and multi-user equipment, or a scenario called multiple UEs cooperative communication (MUCC for short), when at least two UEs support WiFi and LTE at the same time, A MUCC relationship is established between these UEs supporting both WiFi and LTE, which can increase reliability and throughput. That is, when one of the UEs needs to send or receive data, other UEs except the UE can provide support to assist the UE to communicate with the base station. The...

Abstract

Provided are a data transmission method, device and system. The method comprises: when a network-side device sends a downlink data packet to a target user equipment, determining a user equipment group to which the target user equipment belongs according to user equipment grouping information, and determining a relay user equipment in the user equipment group to which the target user equipment belongs, the user equipment in the user equipment group communicating with one another via a local network, and the user equipment grouping information comprising the correlation between a user equipment and a group identifier of a user equipment group to which the user equipment belongs; and the network-side device sending the downlink data packet to the target user equipment through the relay user equipment in the user equipment group to which the target user equipment belongs, the downlink data packet comprising a macro network identifier of the target user equipment. With the assistance of a relay user equipment, a target user equipment receives a downlink data packet sent by a network-side device, thus improving the throughput and communication rate of the target user equipment.

Description

technical field [0001] Embodiments of the present invention relate to communication technologies, and in particular, to a data transmission method, device, and system. Background technique [0002] With the rapid development of mobile communication technology, mobile communication systems of various standards have appeared, for example, Global System of Mobile Communication (GSM for short) network, General Packet Radio Service (General Packet Radio Service for short), GPRS) network, Wideband Code Division Multiple Access (WCDMA for short) network, CDMA-2000 network, Time Division-Synchronous Code Division Multiple Access (TD-SCDMA for short) network, global microwave Worldwide Interoperability for Microwave Access (WiMAX for short) network, etc. These mobile communication systems usually provide data communication services in addition to voice communication services. Therefore, users can use the data communication services provided by these mobile communication systems to u...
