Solution Overview
Problem
Existing wireless communication systems face challenges in efficiently managing slot aggregation and beam selection in full duplex mode, leading to interference and reduced communication reliability.
Innovation Solution
A method and apparatus for wireless communications that involve receiving an indication of a configuration of aggregated slots, determining different beam pairs for uplink and downlink communications during specific subsets of aggregated slots, and communicating using these beam pairs to reduce interference and improve efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If slot aggregation is implemented in full duplex mode, then communication reliability is improved, but self-interference increases
Solution Approach 1:
The patent divides the aggregated slots into different subsets, where first subset slots are configured for downlink communications and second subset slots are configured for uplink communications. This segmentation separates the harmful self-interference periods from the reliable communication periods, allowing the system to benefit from slot aggregation while mitigating interference through temporal separation of transmit and receive operations.
2Productivity
If beam switching is performed during aggregated slots, then spectral usage efficiency is improved, but device complexity increases
Solution Approach 1:
The patent dynamically configures different beam pairs for different subsets of aggregated slots based on the communication direction (uplink or downlink). The system adapts beam selection in real-time according to the slot subset being used, enabling optimal spectral usage for each communication type while managing complexity through structured, rule-based beam switching rather than arbitrary changes.

AI summary
Methods, systems, and devices for wireless communications are described. A communication device, such as a base station and a user equipment (UE) may communicate in a full duplex mode. The base station may transmit, to the UE, an indication of a configuration of a set of aggregated slots for wireless communications in the full duplex mode. The UE or the base station, or both, may determine a first beam pair for communications during a first subset of the aggregated slots. The UE or the base station, or both, may determine a second beam pair for communications during a second subset of the aggregated slots. The UE or the base station, or both, may communicate the wireless communications using the first beam pair during the first subset of aggregated slots and the second beam pair during the second subset of aggregated slots.
