    Abstract: A method for operating a communications controller adapted for full duplex (FD) operation includes receiving a measurement report from a user equipment served by the communications controller, the measurement report indicating a first power margin between a current transmit power and a transmit power break point and a second power margin between the current transmit power and a maximum transmit power capable of supporting FD operation, performing FD link adaptation (LA) in accordance with the first power margin and the second power margin to adjust one or more FD configuration parameters of a link between the communications controller and the user equipment, wherein the link includes a downlink and an uplink, and instructing the user equipment to communicate over the link in accordance with the one or more FD configuration parameters.

    Abstract: A BS determines an amount of resource overloading for a contention transmission unit (CTU) access region associated with a grant-free uplink transmission scheme in a multiple access system. The BS determines a modulation and coding scheme (MCS) limit indicating a maximum MCS level for the CTU access region. The BS sends the MCS limit to a plurality of user equipments (UEs) associated with the first CTU access region. A UE receives from the base station the MCS limit and determines a first MCS index within the MCS limit for a first uplink transmission. The UE sends the first uplink transmission to the base station using a CTU in the CTU access region. The first uplink transmission includes user data and the first MCS index determined at the first UE.

    Abstract: Embodiments are provided for cross-polarized antennas design with different down tilt angles that support versatile functionality, such as for MIMO or beamforming. An embodiment antenna circuit comprises a baseband signal processor, a pair of RF transmitters coupled to the baseband signal processor, a pair of PAs coupled to the RF transmitters, a 90°/180° hybrid coupler coupled to the RF transmitters, a pair of duplexers and two antennas coupled to the PAs. The two antennas are down tilted at different down tilt angles. A pair of signals is generated using the baseband signal processor, transmitted by the RF transmitters, and amplified using the PAs. Additionally, a 90° or 180° phase difference is introduced into the signals using the 90°/180° hybrid coupler. After the amplifying and introducing the phase difference, the signals are polarized at two different polarizations and down tilted at different down tilt angles using the two antennas.
