Abstract
Aspects of the disclosure are directed to generation of N-port dynamic beams. For example, a user equipment (UE) may be using a 2-port predefined receive beam for communication with a wireless node. The UE may estimate a channel using the predefined receive beam to measure a rank2 reference signal received from the wireless node. The UE may generate a dynamic beam weight to maximize a communication parameter based on the estimated channel. The UE may then apply the dynamic beam weight to an antenna array.
Claims30
A method of wireless communication at a user equipment (UE), comprising:
- estimating a channel using one or more predefined receive beams to measure a rank2 reference signal received from a wireless node;
- generating a dynamic beam weight to maximize a communication parameter based on the estimated channel;
- and
- applying the dynamic beam weight to an antenna array.
An apparatus for wireless communication, comprising:
- one or more memories, individually or in combination, having instructions;
- and
- one or more processors, individually or in combination, configured to execute the instructions and cause the apparatus to:
- estimate a channel using one or more predefined receive beams to measure a rank2 reference signal received from a wireless node;
- generate a dynamic beam weight to maximize a communication parameter based on the estimated channel;
- and
- apply the dynamic beam weight to an antenna array.
An apparatus for wireless communication, comprising:
- means for estimating a channel using one or more predefined receive beams to measure a rank2 reference signal received from a wireless node;
- means for generating a dynamic beam weight to maximize a communication parameter based on the estimated channel;
- and
- means for applying the dynamic beam weight to an antenna array.
A non-transitory, computer-readable medium comprising computer executable code, the code when executed by one or more processors causes the one or more processors to, individually or in combination:
- estimate a channel using one or more predefined receive beams to measure a rank2 reference signal received from a wireless node;
- generate a dynamic beam weight to maximize a communication parameter based on the estimated channel;
- and
- apply the dynamic beam weight to an antenna array.
