Title: MULTI-ANTENNA TRANSMISSION PROTOCOLS FOR HIGH DOPPLER CONDITIONS
Abstract:
In response to a metric (e.g., Doppler metric) exceeding a threshold, a network node device can facilitate transmitting a message instructing a user equipment to enable reception of transmission signals having a precoding rank value of one. The network node device can send a reference signal having the precoding rank value of one, and receive feedback from the user equipment comprising an indicator of channel quality. Optionally, in response to the metric exceeding a threshold, the network node device can facilitate transmitting a message instructing the user equipment to respond to a reference signal by providing feedback comprising a first indicator of rank having a value of one, and a second indicator of channel quality.
