PHYSICAL RANDOM ACCESS CHANNEL FOR UPLINK-SUBBAND IN SUBBAND FULL DUPLEX - A simplified explanation of the abstract

This abstract first appeared for US patent application 18049212 titled 'PHYSICAL RANDOM ACCESS CHANNEL FOR UPLINK-SUBBAND IN SUBBAND FULL DUPLEX

Simplified Explanation

The abstract describes methods, systems, and devices for wireless communications, specifically focusing on subband full duplex (SBFD) slots and random access channel (RACH) configurations for SBFD slots. Here are some key points to explain the patent:

• User equipment (UE) receives control signaling for SBFD slots and RACH configurations.
• The UE transmits RACH messages in an uplink subband of an SBFD slot based on the RACH configuration.
• The RACH configuration allows the UE to repeat or transmit multi-slot RACH messages across SBFD slots and uplink slots.
• Synchronization signal blocks (SSBs) are mapped to RACH occasions in the uplink subband of the SBFD slot.
• SSBs may be mapped across multiple consecutive SBFD slots.
• The RACH configuration enables the UE to repeat or transmit multi-slot RACH messages across multiple SBFD slots.

Original Abstract Submitted

Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive control signaling that indicates a configuration for subband full duplex (SBFD) slots and a random access channel (RACH) configuration for SBFD slots. The UE may transmit at least one instance of a RACH message in an uplink subband of an SBFD slot in accordance with the RACH configuration. The RACH configuration may enable a UE to repeat a RACH message or transmit a multi-slot RACH message across an SBFD slot and an uplink slot. The RACH configuration may map synchronization signal blocks (SSB)s to RACH occasions in the uplink subband of the SBFD slot. In some examples, the SSBs may be mapped across multiple (e.g., consecutive) SBFD slots. In some cases, the RACH configuration may enable a UE to repeat a RACH message or transmit a multi-slot RACH message across multiple SBFD slots.
