    Abstract: Technology for user equipment (UE)-specific assigning of demodulation reference signal (DM-RS) sequences to support uplink (UL) coordinated multipoint (CoMP) is disclosed. One method can include a DM-RS sequence assignment device sorting the plurality of UE into a list according to a number of reception point (RP) links for each UE in a CoMP set, and assigning a base DM-RS sequence and a cyclic shift (CS) to a top-ranked UE from the list. The top-ranked UE can have a highest number of RP links. The DM-RS sequence assignment device can repeatedly assign a different CS of the base DM-RS sequence to a plurality of unassigned UE in a same cell as the top-ranked UE, and repeatedly assign the different CS of the base DM-RS sequence to a plurality of unassigned UE in a cooperatively served cell of the top-ranked UE.

    Abstract: Wireless-device-to-wireless device (WD-WD) interference in a full-duplex wireless network is managed by an uplink transmit power control technique that minimizes interference experienced in downlink signals at other wireless devices in the wireless network. In one exemplary embodiment, an instantaneous antenna gain of the wireless device and a target uplink Signal-to-Interference-plus-Noise Ratio (SINR) of an uplink signal of the wireless device to the home base station are determined at the wireless device. A Noise plus Interference level at the home base station is received by either a closed-loop or an open-loop feedback technique. The uplink power level for an uplink signal of the wireless device is determined based on the determined antenna gain, the determined target uplink SINR and the received Noise plus Interference level at the home base station.
