Abstract
Example embodiments are directed towards beam formation matching for communications between a receiver and transmitter in a multiple beam Multiple Input Multiple Output (MIMO) system.
Claims20
A processor of a base station configured to perform operations, comprising:
- transmitting reference signal configurations to a user equipment (UE), each reference signal configuration corresponding to one transmitter beam;
- transmitting beam identification information to the UE comprising at least an indication that one or more reference signal configuration is repeated in time using a same transmitter beam;
- transmitting reference signals according to the reference signal configurations;
- and
- receiving, from the UE, a message comprising an indication of a selected-transmitter beam based on the reference signals.

A base station, comprising:
- radio frequency (RF) circuitry configured to communicate with a network;
- and
- a processor communicatively coupled to the RF circuitry and configured to perform operations comprising:
- transmitting reference signal configurations to a user equipment (UE), each reference signal configuration corresponding to one transmitter beam;
- transmitting beam identification information to the UE comprising at least an indication that one or more reference signal configuration is repeated in time using a same transmitter beam;
- transmitting reference signals according to the reference signal configurations;
- and
- receiving, from the UE, a message comprising an indication of a selected-transmitter beam based on the reference signals.
5 more elements
One or more non-transitory computer-readable media comprising instructions to cause an electronic device, upon execution of the instructions by one or more processors of the electronic device, to perform operations, comprising:
- transmitting reference signal configurations to a user equipment (UE), each reference signal configuration corresponding to one transmitter beam;
- transmitting beam identification information to the UE comprising at least an indication that one or more reference signal configuration is repeated in time using a same transmitter beam;
- transmitting reference signals according to the reference signal configurations;
- and
- receiving, from the UE, a message comprising an indication of a selected-transmitter beam based on the reference signals.
