BEAM SWITCH RULES ASSOCIATED WITH SWITCHING BETWEEN MULTIPLE TRANSMISSION AND RECEPTION POINT (mTRP) and SINGLE TRP (sTRP) - A simplified explanation of the abstract
This abstract first appeared for US patent application 18447895 titled 'BEAM SWITCH RULES ASSOCIATED WITH SWITCHING BETWEEN MULTIPLE TRANSMISSION AND RECEPTION POINT (mTRP) and SINGLE TRP (sTRP)
Simplified Explanation
The abstract describes a method for updating the number of Transmission Configuration Indicator (TCI) states in a unified transmission framework based on the switch between single and multiple Transmission and Reception Point (TRP) modes. Here is a simplified explanation of the patent application:
- User equipment (UE) receives downlink control information (DCI) indicating a first number of TCI states and downlink information indicating a second number of TCI states.
- The UE detects a switch between multiple TRP (mTRP) and single TRP (sTRP) modes based on the difference between the first and second numbers of TCI states.
- The UE communicates in a channel configured to use a selected TCI state associated with the first number of TCI states using a predefined rule based on the switch between the mTRP and sTRP modes.

- Unanswered Questions
- How does this method impact network latency in real-world scenarios?
The abstract does not mention the potential effects of this method on network latency during the switch between different TRP modes.
- Are there any limitations to the predefined rule for selecting TCI states?
It is not clear from the abstract if there are any constraints or drawbacks to the predefined rule used for selecting TCI states based on the switch between mTRP and sTRP modes.
Original Abstract Submitted
In a unified transmission configuration indicator (TCI) framework, certain channels are preconfigured to use a fixed number of TCI states. However, these preconfigured channels are not currently updated when the number of TCI states dynamically change during a switch between single and multiple transmission and reception point (TRP) modes. To alleviate this problem, a user equipment (UE) may receive downlink control information (DCI) indicating a first number of TCI states and, prior to the DCI, downlink information indicating a second number of TCI states, detect a switch between the multiple TRP (mTRP) and single TRP (sTRP) modes based on the first number of TCI states being different than the second number of TCI states, and communicate in a channel configured to use a selected TCI state associated with the first number of TCI states using a predefined rule based on the switch between the mTRP and sTRP modes.
