Abstract: A method for operating a user equipment (UE) includes detecting an occurrence of an overheating condition in the UE, and based thereon, determining a first set of operating capabilities of the UE from a second set of operating capabilities of the UE, where the first and second set of operating capabilities are associated with a connection between the UE and a network entity, and where the first set of operating capabilities is a reduction in operating capability of the UE when compared to the second set of operating capabilities, triggering a transfer of UE capability information associated with the first set of operating capabilities, and applying, by the UE, the first set of operating capabilities to the connection.

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.
