    Abstract: Devices and methods of providing joint scheduling in a full-duplex LTE system are generally described. The UE measures intra-cell interference at the UE caused by a UL transmission from each intra-cell UE, calculates a ratio of the intra-cell interference over an average inter-cell interference, determines whether the intra-cell UE is an aggressor or non-aggressor based on whether the ratio exceeds a threshold, transmits at least some of the determinations to the eNB as feedback, and communicates with the eNB based on a schedule that is dependent on the feedback such that the UE is neither an aggressor nor is subject to interference from aggressors. The schedule may also be based on wideband CQI feedback based on a ratio of an average overall DL interference plus noise over the average inter-cell interference plus noise and/or subband. CQI feedback based on SINR measurements.

    IPC: H04B1/16

    Abstract: A receiver circuit associated with a communication device is disclosed. The receiver circuit comprises a digital data compression circuit configured to receive a plurality of digital receive signals derived from a plurality of analog receive signals respectively associated with the receiver circuit. The digital data compression circuit is further configured to compress the plurality of digital receive signals to form one or more compressed digital data signals based thereon, to be provided to an input output (I/O) interface associated therewith. In some embodiments, a compressed digital signal dimension associated with the one or more compressed digital data signals is less than a digital signal dimension associated with the plurality of digital receive signals.

    Abstract: 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
