Abstract
Preceded contention reservation signals for synchronous new radio (NR) shared spectrum (NR-SS) networks are disclosed. A transmitter that uses precoded contention reservation signals may be configured either to skip or use the training phase for determining rank parameters. The transmitter participates in contention resolution with its receiver by transmitting the precoded contention reservation signals precoded with tentative rank parameters. After contention interval, receiver sends feedback to the transmitter identifying proposed rank parameters based on the strongest precoded contention signals of any neighboring nodes that also won access to the channel. When configured to skip the training phase, the transmitter sets the rank parameters according to the proposed rank parameters. Otherwise, the transmitter participates in the training phase with other winning nodes transmitting signals identifying proposed rank parameters. The receiver then feeds back refined rank parameters to the transmitter based on each of the proposed rank parameters of the training phase.
