Abstract

The embodiment of the invention provides an uplink transmission method, an uplink configuration method, a terminal and a base station. The method at the terminal side comprises the following steps: acquiring configuration information of uplink reference signal resources configured for the terminal by the base station; sending an uplink reference signal according to the configuration information ofthe uplink reference signal resource; enabling the terminal to receive uplink transmission indication information determined by the base station; and performing uplink transmission according to the indication information. The scheme of the invention provides a sending and receiving scheme of the interaction information of the terminal and the base station with respect to the coherent transmissioncapability of the sending path, and an interaction scheme of signaling such as resource configuration, uplink access permission and the like based on the interaction scheme, thereby ensuring the uplink transmission performance of the terminal.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to an uplink transmission, a configuration method, a terminal and a base station. Background technique [0002] In LTE Rel-8, up to 4 layers of MIMO transmission can be supported. [0003] Rel-9 focuses on enhancing the MU-MIMO technology. The MU-MIMO (Multi-User MIMO) transmission of TM (Transmission Mode)-8 can support up to 4 downlink data layers. [0004] Rel-10 introduces support for 8 uplink reference signal ports to further improve the spatial resolution of channel state information, and further expands the transmission capability of SU-MIMO (Single-User MIMO) to a maximum of 8 data layers. [0005] Rel-13 and Rel-14 introduced FD-MIMO technology support to 32 ports to achieve full-dimensional and vertical beamforming. [0006] In order to further improve the MIMO technology, large-scale antenna technology is introduced into the mobile communication system. ...
