UPLINK TRANSMISSION TIMING PATTERNS

Title:

UPLINK TRANSMISSION TIMING PATTERNS

Document Type and Number:

WIPO Patent Application WO/2021/047539

Kind Code:

A1

Abstract:

Methods, systems, and devices for wireless communications are described. A communication device, otherwise known as a user equipment (UE) may receive an indication of an uplink transmission timing pattern configuration for transmitting uplink transmissions on a first carrier. The UE may identify to use both the first carrier and a second carrier during a single uplink transmission mode, where the UE may transition between sending the uplink transmissions on the first and second carriers. The UE may also determine, based on the uplink transmission timing pattern configuration, a timing of uplink carrier switching periods for retuning between transmissions on the first carrier and on the second carrier. As a result, the UE may transmit, during the single uplink transmission mode, on both the first carrier and the second carrier in accordance with the uplink transmission timing pattern configuration for the first carrier and the uplink carrier switching periods.
