Abstract

The invention provides a data sending and receiving method, user equipment, base station and gateway. Among them, a data sending method includes: a first UE sends a data packet to a second UE in D2D mode; the first UE receives a handover instruction sent by a base station; the first UE sends the first unsuccessful packet in D2D mode to the second UE. The UE's data packet and subsequent data packets are sent to the base station, so that the base station forwards them to the second UE. The technical solution of the present invention completes the switching between the cell mode and the D2D mode for UEs communicating with each other.

Description

technical field [0001] The present invention relates to communication technology, in particular to a data sending and receiving method, user equipment, base station and gateway. Background technique [0002] Currently, there are more and more communication networks, such as a residential network, a wireless local area network (Wireless Local Area Network, WLAN), a Bluetooth (BlueTooth, BT) and the like. In a cell network, when a user equipment (User Equipment, UE) communicates with other UEs, it needs to be centrally controlled by a base station, such as an evolved base station (evolved NodeB, eNB) in a Long Term Evolution (Long Term Evolution, LTE) network , this communication mode is called cell mode communication. The advantage of the communication between UEs being controlled by the base station is that the base station can centrally control the use of radio resources of the cell and perform good interference control. However, in some cases, for example, when two UEs a...
