1Object-affected harmful factors
If conventional isolation techniques are used between collocated transceivers, then isolation between radios is improved, but transmit power and throughput performance deteriorate
Solution Approach 1:
The patent applies dynamics by dynamically determining transmit power levels and transmission packet rates based on real-time channel conditions and interference levels. The system continuously adjusts these parameters to optimize both isolation between transceivers and throughput performance, rather than using fixed conventional isolation techniques that sacrifice throughput.
Solution Approach 2:
The patent changes key transmission parameters (transmit power level and packet rate) to resolve the contradiction. By adjusting these parameters based on measured signal strength and noise metrics, the system achieves effective isolation between collocated transceivers while maintaining high throughput, avoiding the performance degradation associated with conventional isolation methods.
2Productivity
If transmit power is increased to maintain throughput, then data throughput is improved, but power leakage between transceivers worsens
Solution Approach 1:
The patent implements feedback by measuring signal strength and noise metrics from the wireless channel, then using this information to dynamically adjust transmit power levels. This closed-loop control ensures that transmit power is increased only when necessary to maintain throughput, thereby minimizing power leakage between collocated transceivers while preserving data throughput performance.
Solution Approach 2:
The system dynamically adjusts transmit power based on real-time channel conditions rather than using fixed high power levels. This dynamic adaptation allows the system to maintain throughput when needed while reducing power leakage during periods of lower interference or when throughput requirements are met at lower power levels.
3Reliability
If isolation switching is implemented between transceivers, then coexistence performance is improved, but device complexity increases
Solution Approach 1:
The patent employs periodic action through time-division multiplexing, where transceivers are periodically switched between isolated and non-isolated states based on transmission requirements. This periodic switching achieves effective isolation and improved coexistence performance while using simple, periodic control logic rather than complex continuous switching mechanisms.
Solution Approach 2:
The patent introduces a medium access grant signal as an intermediary that coordinates switching operations between collocated transceivers. This signal acts as a mediator to manage access and isolation, simplifying the control logic required for switching operations while maintaining effective isolation and improving overall coexistence performance.

AI summary
Systems, methods, and devices enhance performance of collocated transceivers in wireless devices. Methods include determining, using a processing device comprising processing elements, a transmit power for a first transceiver of a wireless device, and determining, using the processing device, a coding rate for a second transceiver of the wireless device based, at least in part, on the determined transmit power, the first transceiver being collocated with the second transceiver. Methods also include determining, using the processing device, a transmission rate for the second transceiver based, at least in part, on the determined coding rate.
