SYSTEMS AND METHODS TO ADJUST A SOUNDING REFERENCE SIGNAL TIMING OFFSET - A simplified explanation of the abstract

This abstract first appeared for US patent application 17454414 titled 'SYSTEMS AND METHODS TO ADJUST A SOUNDING REFERENCE SIGNAL TIMING OFFSET

Simplified Explanation

The patent application describes a method of wireless communication for a user equipment (UE) operating in a Dual SIM Dual Standby (DSDS) mode. Here are the key points:

  • The UE operates with two SIM cards, with the first SIM designated as the default data subscription (DDS).
  • The UE transmits a sounding reference signal (SRS) from a communication port, with the timing offset assigned by the network associated with the first SIM.
  • The UE receives paging messages from the network associated with the second SIM.
  • To avoid collision between the SRS and paging messages, the UE determines an offset adjustment.
  • The UE sends a request to the network associated with the first SIM to adjust the timing offset based on the offset adjustment.
  • The UE receives an offset change configuration from the network associated with the first SIM.

Potential applications of this technology:

  • Dual SIM smartphones or devices that require efficient wireless communication between multiple SIM cards.
  • Networks or service providers that offer Dual SIM services and want to optimize the timing offset for better performance.

Problems solved by this technology:

  • Avoiding collision between the sounding reference signal and paging messages, which can lead to interference and communication issues.
  • Ensuring efficient and reliable wireless communication in a Dual SIM Dual Standby mode.

Benefits of this technology:

  • Improved performance and reliability of wireless communication in Dual SIM devices.
  • Optimized timing offset adjustment to avoid interference and collisions.
  • Enhanced user experience with seamless and uninterrupted communication.


Original Abstract Submitted

A method of wireless communication performed by a user equipment (UE) includes: operating in a Dual SIM Dual Standby (DSDS) mode in which a first subscriber identity module (SIM) is designated as a default data subscription (DDS); transmitting a sounding reference signal (SRS) from a communication port of the UE, wherein the SRS has a timing offset assigned by a network associated with the first SIM; receiving paging messages from a network associated with a second SIM; determining an offset adjustment to avoid a collision between the SRS and the paging messages; sending a request to the network associated with the first SIM to adjust the timing offset according to the offset adjustment; and receiving an offset change configuration from the network associated with the first SIM.
