Embodiment Construction

[0104] The embodiment of the present invention provides a data transmission method and network equipment. See figure 2 , figure 2 It is a system architecture diagram of a communication system supporting FDD (Frequency Division Multiplexing, Frequency Division Multiplexing) provided by an embodiment of the present invention, and includes core network equipment, network equipment, and user equipment. The example communication system may be, for example, an existing LTE communication system, or a future communication system using 5G New Air Interfaces (NR) technology. Taking an LTE communication system as an example, the core network equipment may include a mobility management entity (Mobility Management Entity, MME) or a serving gateway (Serving GateWay, S-GW), where the MME is mainly responsible for signaling processing, that is, control plane functions, including Access control, mobility management, attach and detach, session management functions, and gateway selection functi...

Abstract

The embodiment of the invention discloses a data transmission method and network equipment. The method includes the following step: the network equipment receives uplink data sent by first user equipment of a first cell during an uplink data receiving time period of the first cell at a first frequency domain resource, and sends downlink data to second user equipment at the first frequency domain resource when receiving the uplink data sent by the first user equipment of the first cell at the first frequency domain resource, wherein the first cell supports a frequency division duplex ( FDD) system, the first user equipment is the user equipment that supports the FDD system, and the second user equipment is the user equipment that supports a time division duplex (TDD) system, or the user equipment that supports the TDD system, the FDD system and carrier aggregation (CA), or the user equipment that supports the FDD system and the CA. The embodiment of the invention is beneficial to the improvement of the spectrum resource utilization of an existing FDD system communication system.

Description

Technical field [0001] The present invention relates to the field of wireless communication technology, in particular to a data transmission method and network equipment. Background technique [0002] The wireless communication system includes uplink and downlink. A base station (base station, BS) may send a signal to user equipment (user equipment, UE) through a downlink, and the user equipment may send a signal to a base station through an uplink. When supporting duplex communication, in order to avoid mutual interference caused by parallel transmission of uplink and downlink signals, it is necessary to separate uplink and downlink signals. [0003] Currently, the duplex modes used in wireless communication systems include frequency division duplexing (FDD) and time division duplexing (TDD). In frequency division duplex mode, different carrier frequencies are used in the uplink and downlink, such as figure 1 As shown in the left figure, f0 is used for downlink and f1 for uplink...
