Abstract: An electronic device may receive, from a radio node, a measurement configuration associated with a wireless communication system. In response, the electronic device may perform measurements using narrow beam patterns based at least in part on a network configuration, where the narrow beam patterns are narrower than a wide beam pattern of the electronic device. Furthermore, performing the measurements using the narrow beams pattern may include performing a beam-pattern search up to the network configuration. Then, the electronic device may perform an SCell activation procedure of an SCell with the radio node. Note that the SCell activation procedure may include reporting, to the radio node, CSI of a narrow beam pattern of the SCell that is to be activated, where the narrow beam pattern is narrower than the wide beam pattern of the electronic device, and the narrow beam pattern is based at least in part on the measurements.

Abstract: Apparatuses, systems, and methods for beam failure recovery based on a unified TCI framework. A UE may receive, from a base station, a configuration for a BFR procedure for a CCG. The CCG may include at least two CCs and the UE may periodically receive, from the base station, at least a first BFD RS and a first CBD RS in a first CC included in the CCG. The UE may detect, based on the first BFD RS, a beam failure in at least the first CC and send, to the base station, a BFRQ. The BFRQ may include a candidate beam selected based on at least the first CBD RS and may be sent via a PRACH or MAC CE. The UE may receive, from the base station, a BFR response and apply the candidate beam to the first CC and at least one additional CC of the CCG.

Abstract: The disclosure relates to methods and devices for improving TX beam forming. A method according to a first approach is for determining an RX beam pattern for a user equipment, UE. A method according to a second approach is for polarization control in TX beam forming of a user equipment, UE. A method according to a third approach is for user equipment, UE, TX beam forming based on UE beam correspondence. A method according to a fourth approach is for re-acquiring a beam pair between a user equipment, UE, and a base station based on grouping information.
