SYSTEMS AND METHODS FOR CONTROL SIGNALING FOR BEAM SEARCHING LATENCY REDUCTION - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240022309 titled 'SYSTEMS AND METHODS FOR CONTROL SIGNALING FOR BEAM SEARCHING LATENCY REDUCTION

Simplified Explanation

The patent application describes systems and methods for reducing latency in beam searching by spatially correlating synchronization signal blocks (SSBs) and selecting transmit beams accordingly. The gNode B (gNB) determines spatial correlation between SSBs, transmits correlation messages to help user equipment (UE) determine spatial correlation, and allows UEs to measure SSBs on subsets of receive beams. In some cases, Channel State Information Reference Signals (CSI-RS) may be measured in place of SSBs.

• GNB determines spatial correlation between SSBs
• GNB selects transmit beams for SSBs based on spatial correlation
• GNB transmits correlation messages to assist UEs in determining spatial correlation
• UEs measure SSBs on subsets of receive beams
• CSI-RS may be measured instead of SSBs

Potential Applications

This technology could be applied in 5G networks, particularly in improving beamforming and reducing latency in communication systems.

Problems Solved

This technology addresses the issue of latency in beam searching, improves synchronization between SSBs, and enhances the efficiency of beamforming in wireless communication.

Benefits

The benefits of this technology include reduced latency, improved beamforming accuracy, enhanced synchronization, and overall better performance in 5G networks.

Potential Commercial Applications

Potential commercial applications of this technology include telecommunications infrastructure, 5G network equipment, and wireless communication devices.

Possible Prior Art

One possible prior art could be related to beamforming techniques in wireless communication systems, but the specific method of spatially correlating SSBs and using correlation messages to assist UEs may be novel.

How does this technology impact battery life in UEs?

The patent application does not address the potential impact of this technology on the battery life of user equipment. It would be important to understand if the increased beamforming efficiency and reduced latency have any implications for power consumption in UEs.

Are there any limitations to the number of SSBs that can be spatially correlated?

The patent application does not specify any limitations on the number of synchronization signal blocks that can be spatially correlated. It would be important to know if there are any constraints on the scalability of this technology in terms of the number of SSBs that can be correlated simultaneously.

Original Abstract Submitted

systems and methods for control signaling for beam searching latency reduction are disclosed herein. a g node b (gnb) may determine that a first synchronization signal block (ssb) and a second ssb are to be spatially correlated and may select a first transmit (tx) beam to transmit the first ssb and a second tx beam to transmit the second ssb accordingly. the gnb may also transmit a correlation message including spatial correlation information to help a ue determine the spatial correlation. the ue may measure the first ssb on a first subset of a plurality of receive (rx) beams and measure the second ssb on a second subset of the plurality of rx beams, and select an rx beam for one or both. in some embodiments, channel state information reference signals (csi-rs) that are quasi co-located (qcled) with a given ssb may be measured in place of the ssb.
