Dynamic switching between different multiple input multiple output operation modes

Abstract:

Generally, the described techniques provide for multiple input multiple output (MIMO) operation mode configuration (e.g., configuration of spatial MIMO, polarization MIMO, or both, across one or more antenna modules of a user equipment (UE)) based on the UE characteristics, channel characteristics, or both. For example, a UE may determine channel characteristics, as well as UE characteristics, for MIMO operation mode configuration. The UE may then feedback, to the base station, MIMO operation information (e.g., channel characteristics, UE characteristics, a request for one or more MIMO operation modes determined by the UE, or some combination thereof) for MIMO operation mode configuration. The base station may receive the MIMO operation information and may determine one or more MIMO operation modes for the UE based on the received MIMO operation information, network conditions, or both. The base station may then transmit a MIMO operation mode configuration to the UE.
