Estimating the term…
An apparatus, method and computer readable medium for special thermal density reduction by antenna thinning. A system comprises N transmit/receive (TX/RX) chains, where each TX/RX chain comprises an RFFE and each RFFE comprises one or more thermal sensors configured to measure heat in the RFFE. An antenna array coupled to the plurality of TX/RX chains. A codebook that comprises a plurality of code words configured to respond to real-time heat measurements from the thermal sensors in each TX/RX chain is configured to switch off selected TX/RX chains to reduce thermal density at the antenna array while maintaining M RFFEs switched on, where M<N and the desired beamforming gain is 10 log 10(M).
An apparatus for a User Equipment (UE), the apparatus comprising:
An apparatus of a base station (BS), the apparatus comprising:
17-18. (canceled)
A non-transitory memory medium storing program instructions for execution by one or more processors that control N TX/RX chains, each TX/RX chain comprising an RF front end (RFFE) coupled to an antenna array, each RFFE comprising one or more thermal sensors configured to measure heat in the RFFE, wherein the program instructions, when executed by the one or more processors, cause the one or more processors to perform operations comprising:
