Layer 1 Beam Reporting Occasions for Panel Information Updates
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication systems face inefficiencies in signaling overhead due to frequent updates of beam information and antenna panel information, leading to increased control signaling and HARQ feedback, especially when antenna panel information is included in every Layer 1 report.
Innovation Solution
Configuring separate sets of transmission occasions with varying periodicities for traditional Layer 1 reports and new Layer 1 reports that include antenna panel information, allowing beam information to be reported more frequently while reducing unnecessary signaling by only transmitting HARQ feedback for reports containing antenna panel information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If antenna panel information is included in every Layer 1 report, then the network has complete information about beam and panel configuration, but control signaling overhead and HARQ feedback increase significantly
Solution Approach 1:
The patent segments the transmission occasions into two separate sets: a first set for traditional L1 reports with beam information only, and a second set for new L1 reports with both beam information and antenna panel information. This segmentation allows the system to transmit complete information (improving reliability) only when necessary, while using simpler reports for frequent updates, thereby reducing overall signaling overhead.
Solution Approach 2:
The patent implements different periodicities for the two types of reports: the first set of transmission occasions uses a first periodicity for frequent beam information updates, while the second set uses a second periodicity for less frequent antenna panel information updates. This periodic action optimizes the balance between information completeness and signaling overhead by updating panel information only when changes occur.
2Productivity
If separate sets of transmission occasions with different periodicities are configured, then beam information can be reported frequently while panel information is reported less frequently, but the system complexity increases
Solution Approach 1:
The patent configures the UE with multiple transmission occasions that can be used for different reporting purposes. The same UE and reporting mechanism can handle both traditional beam information reports and enhanced reports with antenna panel information, making the system multi-functional without requiring completely separate reporting mechanisms.
Solution Approach 2:
The patent dynamically configures which transmission occasion to use based on the type of information being reported. The network can flexibly assign different periodicities to different report types, allowing the system to adapt to changing requirements and optimize reporting efficiency while managing complexity through flexible configuration rather than rigid fixed structures.
3Reliability
If HARQ feedback is transmitted for all L1 reports, then all reports are acknowledged and processed, but network load and processing requirements increase
Solution Approach 1:
The patent applies different HARQ feedback mechanisms to different types of reports: traditional L1 reports (first set of transmission occasions) may use one feedback mechanism while new L1 reports with antenna panel information (second set) use a different feedback mechanism. This local differentiation allows the network to process reports with appropriate detail levels, reducing overall processing load while maintaining reliability where needed.

AI summary
Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive control signaling indicating a set of transmission occasions usable by the UE for transmitting layer one (L1) reports. The set of transmission occasions may include a first subset of transmission occasions for transmitting beam information reports and a second subset of transmission occasions for transmitting beam information reports and corresponding antenna port information. The UE may then transmit, within a first transmission occasion of the first subset of transmission occasions, a first L1 report including a first beam information report, and may transmit, within a second transmission occasion of the second subset of transmission occasions, a second L1 report including a second beam information report and an indication of a quantity of antenna ports supported by the UE.
