==MULTI-BURST A-TRS FOR LOOP OPERATION ON SSB-LESS SECONDARY CELL IN INTER-BAND CARRIER AGGREGATION - A simplified explanation of the abstract==


This abstract first appeared for US patent application 17937269 titled 'MULTI-BURST A-TRS FOR LOOP OPERATION ON SSB-LESS SECONDARY CELL IN INTER-BAND CARRIER AGGREGATION

==Simplified Explanation==

The present disclosure involves a method for a User Equipment (UE) to request and receive A-TRS (Additional-Reference Signal) in a secondary carrier on a different frequency band, improving reception performance of downlink data transmissions.

* UE requests base station to configure and transmit A-TRS in a secondary carrier on a different frequency band.
* UE transmits request for A-TRS in a first cell served by an anchor carrier.
* UE receives A-TRS in a second cell lacking SSB transmissions served by the secondary carrier.
* Base station controls transmission of A-TRS in the secondary cell based on a timer derived from the request.
* UE applies AGC and time/frequency tracking loop operations using A-TRS before receiving a PDSCH in the secondary cell.

### Potential Applications
- Improved reception performance in downlink data transmissions.
- Energy savings in inter-band CA (Carrier Aggregation).

### Problems Solved
- Enhancing reception performance in secondary carriers without SSB transmissions.
- Efficient utilization of A-TRS for signal processing operations.

### Benefits
- Enhanced data transmission reliability.
- Improved network energy efficiency.
- Better user experience with optimized signal processing.

### Potential Commercial Applications
#### Enhanced Downlink Data Transmission Technology for Mobile Networks

### Possible Prior Art
There may be prior art related to optimizing signal processing operations in mobile networks to improve reception performance, but specific implementations involving requesting and receiving A-TRS in a secondary carrier on a different frequency band may be novel.

#### Unanswered Questions
#### How does this method impact network latency in data transmissions?
This article does not address the potential impact of the method on network latency in downlink data transmissions.

#### What are the potential challenges in implementing this method on a large scale in existing mobile networks?
The article does not discuss the potential challenges or limitations in implementing this method on a large scale in current mobile network infrastructures.


==Original Abstract Submitted==

Aspects of the present disclosure allow a UE to request, in an anchor carrier on one frequency band, a base station to configure and transmit A-TRS in an SSB-less secondary carrier on a different frequency band. The UE transmits, in a first cell served by the anchor carrier, a request for A-TRS. Based on the request, the UE receives, in a second cell lacking SSB transmissions served by the secondary carrier, the A-TRS based on the request. The base station may also control transmission of the A-TRS in the SSB-less secondary cell based on a timer derived from the request. Using the A-TRS, the UE may apply AGC and time/frequency tracking loop operations prior to receiving a PDSCH in the SSB-less secondary cell, thereby improving reception performance of downlink data transmissions in the secondary carrier. Thus, network energy savings provided by SSB-less secondary carriers may be obtained in inter-band CA.
