Abstract: A method for wireless communication by a user equipment (UE) includes receiving, from a network node, a message configuring a group of component carriers (CCs). The method also includes allocating, to each CC of the group of CCs based on receiving the message configuring the group of CCs, one of a respective first number of receiver chains, from a group of receiver chains available at the UE, or a respective second number of receiver chains, from the group of receiver chains, to maximize a total number of receiver chains for decoding the group of CCs, collectively. The method further includes decoding each CC of the group of CCs based on the respective first number of receiver chains or the respective second number of receiver chains allocated to the CC.

Abstract: A charging system may include a plurality of power modules, a distributing switch module, and a plurality of charging ports. The distributing switch module includes a first distributing unit and a second distributing unit. The first distributing unit may connect a first part of power modules in the plurality of power modules to a first charging port, to distribute powers of the first part of power modules to the first charging port. The second distributing unit may connect a second part of power modules in the plurality of power modules to a second charging port, to distribute powers of the second part of power modules to the second charging port. Therefore, the first charging port may charge a first terminal, and the second charging port may charge a second terminal.

Abstract: Certain aspects of the present disclosure provide a method for wireless communications by a wireless device. The wireless device evaluates a plurality of antenna group combinations based on one or more criteria wherein each antenna group combination includes at least two antenna groups of multiple antennas and the one or more criteria involve a first performance value calculated separately for each antenna group in an antenna group combination under evaluation and a second performance value calculated collectively for the at least two antenna groups in the antenna group combination under evaluation. The wireless device selects a subset of the plurality of antenna group combinations, based on the evaluation.
