Abstract

The present disclosure relates to methods and devices for sending and receiving data. Specifically, a communication method is provided. The method includes: performing precoding on data in a plurality of resource elements (REs) of at least one physical resource block (PRB) based on a predetermined first precoding scheme, cyclically applying a plurality of resource elements (REs) in a predetermined order to the plurality of REs. Different co-phase precoding schemes in order to encode data in REs. In addition, another communication method is provided, the method includes receiving data in a plurality of REs of at least one PRB transmitted from a device; and performing pre-decoding on the data based on a predetermined first pre-decoding scheme, for the plurality of REs, Multiple different co-phase precoding schemes are applied cyclically in a predetermined order in order to decode data in REs. Also disclosed are network equipment and terminal equipment capable of implementing the above method.

Description

technical field [0001] Embodiments of the present disclosure relate to the field of wireless communication, and more particularly to methods and devices for sending and receiving data. Background technique [0002] With the development of mobile communication technology, especially the arrival of the fifth generation mobile communication technology (5G), multiple-input multiple-output (MIMO) antenna arrays or "massive MIMO" have attracted much attention. At present, two-dimensional (2D) active antenna array (Active Antenna Array, AAA) system has been adopted to form three-dimensional (3D) beams in both vertical domain and horizontal domain, and more antenna ports can be supported in closed-loop MIMO transmission mode . However, in high mobility scenarios, an open loop (Open Loop, OL) MIMO transmission mode is more applicable. [0003] In the current LTE system, OL transmission modes are defined as transmission mode 2 (TM2) and transmission mode 3 (TM3). TM2 is a Space-Fre...
