A computer readable storage device comprising executable instructions that, in response to execution, cause a system comprising a processor to perform operations, comprising:

• selecting a subset of uplink user devices of a set of uplink user devices based on a potential for low inter-user stream interference between uplink user devices of the subset of uplink user devices;
• selecting a linear transceiver matrix used in connecting the subset of uplink user devices to a base station device, based on an availability of a data link and a full-duplex signal transmission criterion that inhibits interference between a set of data streams associated with the subset of uplink user devices and a set of downlink user devices, wherein the full-duplex signal transmission criterion defines whether the subset of uplink user devices generate a data transmission rate satisfying a target data transmission rate in connection with the set of downlink user devices configured for connection to the base station device;
• determining a group of data streams of the set of data streams for transmission based on a number of data streams that correspond to the set of data streams and a set of channel matrices;
