Problems solved by technology

Rainfall and atmospheric gases (such as oxygen and vegetation) have the potential to further increase attenuation compared to frequencies below 6GHz
Also, at higher frequencies (e.g. at mmWave frequencies), penetration and diffraction attenuation can be more severe
[0005] All of these

[0026] Beam-based 5G radio access

[0027] Recent channel measurements performed by the wireless industry and academia have demonstrated the feasibility of achieving satisfactory cellular coverage with beamforming techniques. Measurements show that beamforming gain provides coverage for cellular control signaling and increases link capacity for higher data throughput under LOS conditions.

[0028] The channel propagation characteristics of 5G NR cellular systems and their high data throughput may require that all physical layer signals and channels, including those used for broadcasting and sharing purposes, as well as focusing on beam-based or beam-centric Beamforming is used on the physical layer signals and channels of the process. 5G NR system designs can be implemented as beamformed access links using beamforming processing for most or all physical layer signals and channels. Different beamforming techniques (including digital, analog, and hybrid beamforming) can be app...

Abstract

Systems and methods described herein are provided for beamforming and uplink control and data transmission techniques. Such techniques enable a UE to maintain at least one beam process for operation with multiple beams and/or points. A beam process may be indicated for transmission or reception over a downlink or uplink physical channel. Power, timing, and channel state information may be specificto a beam process. A beam process may be established as part of a random access procedure in which resources may be provisioned in random access response messages. Techniques are provided to handle beam process failures, to use beam processes for mobility, and to select beams using open-loop and closed-loop selection procedures.
