Abstract

The invention provides a signal transmission method and device, a terminal and network side equipment, and the method comprises the steps: receiving at least two groups of first indication informationtransmitted by the network side equipment, with each group of first indication information being used for indicating at least one first signal resource; sending a first signal according to the indication of the at least two groups of first indication information; wherein the first signal comprises a plurality of data layers, and each data layer of the first signal has a corresponding relationshipwith one group of first indication information. According to the embodiments of the present invention, multiple data layers can perform multi-antenna panel joint transmission from multiple antenna panels at the same time, and the network side equipment can independently select a shaped beam for each antenna panel, thereby obtaining a better shaped gain and improving the performance of uplink transmission.

Description

technical field [0001] The present invention relates to the field of communication technologies, and in particular to a signal transmission method, device, terminal and network side equipment. Background technique [0002] In view of the important role of MIMO (Multiple-Input Multiple-Output) technology in improving the peak rate and system spectrum utilization, LTE (Long Term Evolution, long-term evolution) / LTE-A (LTE-Advanced, the evolution of LTE ) and other wireless access technology standards are built on the basis of MIMO+OFDM (Orthogonal Frequency Division Multiplexing, Orthogonal Frequency Division Multiplexing) technology. The performance gain of MIMO technology comes from the spatial freedom obtained by multi-antenna systems. Therefore, one of the most important evolution directions of MIMO technology in the standardization development process is the expansion of dimensions. [0003] In LTE Rel-8, up to 4 layers of MIMO transmission can be supported. Rel-0 focuse...
