Abstract

The invention provides a beam processing method and device, a terminal and network side equipment. The method comprises the following steps: receiving first indication information sent by the networkside equipment; determining a sending beam corresponding to a first antenna panel of the terminal according to the first indication information; determining sending beams of antenna panels except thefirst antenna panel according to the sending beams corresponding to the first antenna panel and the relative relationship among the sending beams of the plurality of antenna panels. The embodiments ofthe present invention can avoid sending a beam training signal on each antenna panel, thereby effectively reducing the overhead of an uplink signal; the network side equipment is prevented from measuring the beam training signal on each antenna panel, and the processing complexity and time delay of the network side equipment are reduced; furthermore, the situation that the network side equipmentconfigures the uplink beam of each antenna panel is avoided, and the configuration overhead of the uplink beam is reduced.

Description

technical field [0001] The present invention relates to the field of communication technologies, and in particular to a beam processing 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 focuses on...
