SYSTEMS AND METHODS TO INCLUDE DEMODULATION REFERENCE SIGNAL BUNDLING IN MULTI-SUBSCRIBER IDENTITY MODULE DEVICES - A simplified explanation of the abstract
- This abstract for appeared for US patent application number 17661173 Titled 'SYSTEMS AND METHODS TO INCLUDE DEMODULATION REFERENCE SIGNAL BUNDLING IN MULTI-SUBSCRIBER IDENTITY MODULE DEVICES'
Simplified Explanation
The abstract describes a method of wireless communication used by a device with two SIM cards. The device operates in a mode where both SIM cards are active simultaneously. The transmit operations of the SIM cards are controlled based on a time division multiplexed (TDM) priority pattern. The first SIM card, which has a higher priority according to the TDM pattern, performs a specific signal bundling process called demodulation reference signal (DMRS) bundling. The priority switch to give the higher priority state to the second SIM card is deferred until after the first SIM card has completed a repetition of DMRS bundling.
Original Abstract Submitted
A method of wireless communication performed by a user equipment (UE) includes: operating in a dual SIM dual active (DSDA) mode with respect to a first subscriber identity module (SIM) and a second SIM; controlling transmit operations of the first SIM and the second SIM according to a time division multiplexed (TDM) priority pattern; performing demodulation reference signal (DMRS) bundling on the first SIM, the first SIM having a higher priority state according to the TDM priority pattern; and deferring a priority switch to give the higher priority state to the second SIM until after the first SIM has completed a repetition of DMRS bundling.
