摘要： A wireless communication device may perform interference alignment and/or cancellation processes when accessing licensed wireless communicaiton spectrum in the role of a secondary user (SU) device of the licensed spectrum. The SU device may perform the interference alignment and/or cancellation processes such that communications of the SU device do not interfere with communications of a primary user (PU) device of the licensed spectrum, such that interference caused by communications of the PU device are mitigated at the SU device, and/or such that interference caused by respective communications of one or more other SU devices accessing the licensed spectrum are mitigated at the SU device. The SU device may communicate using a null space in the licensed spectrum that is associated with the SU device and the PU device. The SU device may use approximation algorithms in performing the interference alignment and/or cancellation processes.

摘要： Methods, systems, and apparatuses are described herein for beamforming based initial access, beam management, and beam based mobility designs for NR systems. Issues are identified and addressed related to, for example, initial access, control channel design, eMBB and URLLC mixing, and beam training.

EP4064586A3 CSI FEEDBACK DESIGN FOR NEW RADIO 审中-公开

IPC分类号： H04B7/06
摘要： It is recognized herein that as the number of transmit antennas in cellular systems (e.g., NR or 5G systems) increase, the Channel State information (CSI) feedback overhead may increase to unacceptable levels, and the current CSI feedback might not support beamforming training for NR. Embodiments described herein provide an enhanced and more efficient design for Channel State Information feedback as compared to current approaches.
