SSB and PRACH Transmissions During Initial Access in Wireless Communications - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240187177 titled 'SSB and PRACH Transmissions During Initial Access in Wireless Communications

Simplified Explanation

The patent application describes a user equipment (UE) that can receive a synchronization signal block (SSB) transmission with a first subcarrier spacing (SCS) in an SSB burst window (SSBW), decode the SSB transmission to determine parameters for a control resource set 0 (coreset #0) to be transmitted in the SSBW using a second SCS that is different from the first SCS, monitor physical downlink control channel (PDCCH) candidates in the determined coreset #0 based on a mapping between the SSB transmission and the coreset #0, and decode the PDCCH and a system information block 1 (SIB1) scheduled by the PDCCH in the SSBW.

• User equipment (UE) receives a synchronization signal block (SSB) transmission with a specific subcarrier spacing (SCS) in a designated SSB burst window (SSBW).
• The UE decodes the SSB transmission to determine parameters for a control resource set 0 (coreset #0) to be transmitted in the SSBW using a different SCS.
• It monitors physical downlink control channel (PDCCH) candidates in the determined coreset #0 based on a mapping between the SSB transmission and the coreset #0.
• The UE decodes the PDCCH and a system information block 1 (SIB1) scheduled by the PDCCH in the SSBW.
