SYNCHRONIZATION SIGNAL BLOCK AND CONTROL RESOURCE SET MULTIPLEXING IN WIRELESS COMMUNICATIONS - A simplified explanation of the abstract
This abstract first appeared for US patent application 18161273 titled 'SYNCHRONIZATION SIGNAL BLOCK AND CONTROL RESOURCE SET MULTIPLEXING IN WIRELESS COMMUNICATIONS
Simplified Explanation
Methods, systems, and devices for wireless communications are described in this patent application. The innovation involves multiplexing a synchronization signal block (SSB) and a control resource set (CORESET) in the frequency domain to form a multiplexed block that is transmitted using a set of symbols. The base station can transmit multiple multiplexed blocks using different beams, with a switching gap between each block to allow for switching of radio frequency (RF) components between beams. The switching gap is longer than the duration of a cyclic prefix (CP) associated with each symbol. Additionally, the SSB within the multiplexed blocks may use a different waveform than the CORESET, while both use a common reference signal.

Original Abstract Submitted
Methods, systems, and devices for wireless communications provide techniques for multiplexing, in a frequency domain, a synchronization signal block (SSB) and a control resource set (CORESET) to form a multiplexed block that is transmitted using a set of symbols. A base station may transmit multiple multiplexed blocks using multiple different beams with a switching gap provided between each multiplexed block that allows for switching of radio frequency (RF) components between different beams. The switching gap is longer than a duration of a cyclic prefix (CP) that is associated with each symbol of the set of symbols of each multiplexed block. Within one or more of the multiplexed blocks, an associated SSB may use a different waveform than the CORESET. The multiplexed blocks may use a common reference signal for both the SSB and CORESET.
