UE Antenna Panel Switching Capability Signaling for Slot Scheduling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless communications systems, the base station is often unaware of the UE's capability to perform antenna panel switches within a time period, leading to sub-optimal uplink interference management and reduced likelihood of successful communication.
Innovation Solution
The UE signals its capability to perform a maximum quantity of antenna panel switches within a time period to the base station, allowing the base station to schedule transmissions accordingly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the base station schedules transmissions without knowing the UE's antenna panel switching capability, then the scheduling flexibility is maintained, but the uplink interference management becomes sub-optimal and communication reliability decreases
Solution Approach 1:
The UE transmits its antenna panel switching capability information to the base station in advance through RRC signaling, MAC-CE, or UCI. This preliminary action ensures the base station has the necessary capability information before making scheduling decisions, enabling optimal uplink interference management and improving communication reliability without compromising scheduling flexibility
2Adaptability or versatility
If the UE performs maximum antenna panel switches within a time period, then the adaptability to different transmission conditions is improved, but the complexity of panel switching management increases
Solution Approach 1:
The UE capability indication specifies a maximum quantity of antenna panel switches that can be performed within a defined time period (e.g., within a slot). By parameterizing the switching capability in terms of quantity and time period, the system achieves adaptability to different transmission conditions while maintaining manageable complexity through standardized capability reporting mechanisms

AI summary
Methods, systems, and devices for wireless communications are described. In some systems, a user equipment (UE) may identify that the UE is capable of performing up to a maximum quantity of antenna panel switches within a slot. For example, the UE may be capable of switching from operating one or more first antenna panels to operating one or more second antenna panels up to a maximum quantity of times within a slot. In some aspects, the UE may transmit an indication of the UE capability to a base station. The base station, based on receiving the indication of the UE capability, may transmit activation signaling indicating one or more antenna panel switches at the UE within a slot that is less than or equal to the maximum quantity of antenna panel switches per slot indicated by the UE capability.
