Abstract

The invention provides a beam measurement reporting method, network side equipment and a mobile terminal; the method comprises the following steps of configuring a measurement parameter and a reporting parameter corresponding to at least one target beam group, wherein the measurement parameter comprises reference signal resources, the reference signal resources corresponding to each target beam group are different, and the reference signal resources corresponding to the beams of at least two TRPs in the at least one target beam group are the same; sending the measurement parameter and the reporting parameter to the mobile terminal; controlling the beams of at least one target beam group to send a reference signal on the corresponding reference signal resource, wherein the reference signalis used for carrying out beam measurement on the mobile terminal and receiving measurement report data of the mobile terminal for carrying out beam reporting on the measurement result according to thereporting parameter. Due to the fact that the measured beams are configured in a grouped mode and the fact that at least two reference signal resources in the at least one target beam group are the same, the number of the reference signal resources allocated in a beam training process can be reduced, so that system overhead is reduced.

Description

technical field [0001] The present invention relates to the field of communication technologies, in particular to a beam measurement reporting method, network side equipment and a mobile terminal. Background technique [0002] LTE (Long Term Evolution) / LTE-A (LTE-Advanced) and other wireless access technology standards are built on the basis of MIMO+OFDM (Orthogonal Frequency Division Multiplexing) technology. Among them, the MIMO technology utilizes the spatial freedom obtained by the multi-antenna system to improve the peak rate and the utilization rate of the system spectrum. [0003] In the process of standardization development, the dimensions of MIMO technology continue to expand. In LTE Rel-8, up to 4 layers of MIMO transmission can be supported. The MU-MIMO technology is enhanced in Rel-9, and the MU-MIMO (Multi-User MIMO) transmission of TM (Transmission Mode)-8 can support up to 4 downlink data layers. In Rel-10, the transmission capability of SU-MIMO (Single-Us...
