Abstract: An apparatus of a base station in a network may include a memory device and a processing device operatively coupled to the memory device. The processing device may process a message received at the base station from a macro-cell base station. The message may include a request to act as a relay for a user equipment (UE). The processing device may then determine that the base station is to act as a relay for the UE. The processing device may then generate a message comprising an indication that the base station accepted the request to act as a relay for the UE.

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.

Abstract: Aspects for interference mitigation in ultra-dense networks are described. Configuration information for at least one co-located hotspot may be determined based on information received from a respective UE of a plurality of UEs and the configuration information may be provided to the at least one co-located hotspot. The configuration information may include an identifier for a channel on which the at least one co-located hotspot is to operate and/or a duration for which the configuration information is to remain valid.

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.
