Title:
CARRIER AGGREGATION WITH DYNAMIC TDD DL/UL SUBFRAME CONFIGURATION
Document Type and Number:
Japanese Patent JP2022043101
Kind Code:
A
Abstract:
To provide a method, apparatus and communication system for avoiding interference in transmission of user equipment (UE) communicating in a carrier aggregation (CA) or multi-connectivity operation using more than one component carrier (CC).SOLUTION: In a wireless communication system, the UE: receives a configuration comprising at least a first CC and a second CC, at least one of which is enabled to use evolved interference management for traffic adaptation (eIMTA) (805); and adapts the hybrid automatic repeat request (HARQ) timing of the UE communications based on changes in the eIMTA and configuration (810). The HARQ timing includes HARQ acknowledgement (ACK) timing or HARQ scheduling timing.SELECTED DRAWING: Figure 8
