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: A base station may transmit beams to user equipment. The user equipment may receive the beams and transmit a signal to a base station. The base station may determine signal characteristics associated with the beams based on the signal and compare the signal characteristics with predefined signal characteristics that correspond to potential locations of the user equipment. Based on this comparison, the base station may determine a position of the user equipment and transmit a targeted beam based on the position of the user equipment. The base station may also track the position of the user equipment and provide an updated targeted beam based on an updated position of the user equipment. Accordingly, the base station may efficiently form and update the targeted beam based on the predefined signal characteristics, thereby reducing an amount of time required to establish and maintain communication with the user equipment.
