Title:
SEMI-STATIC SLOT CONFIGURATION FOR TIME DIVISION MULTIPLEXED UPLINK CARRIERS
Document Type and Number:
WIPO Patent Application WO/2021/047293
Kind Code:
A1
Abstract:
This disclosure provides systems, methods and apparatuses for semi-static slot configuration for time division multiplexed uplink carriers. Efficiency of configuring a slot pattern to be used on multiple uplink carriers may be improved by configuring one or more cell-specific slot patterns for each user equipment (UE) located in a cell associated with a base station and using UE-specific signaling to modify or activate a particular cell-specific slot pattern. Enabling a UE to switch among slot patterns may improve UE performance based on a location of the UE within the cell, such as by signaling the UE to operate according to a first slot pattern in which uplink slots are assigned to a higher frequency band to enable higher data rate transmissions at a cell center, or according to a second slot pattern in which uplink slots are assigned to a lower frequency band to improve coverage at a cell edge.
