    Abstract: A technique is provided for selecting precoding weights in a wireless network to avoid violating a power constraint. The technique may include selecting, by an access point in a wireless network, a set of precoding weights subject to a power constraint, and applying, by the access point, the set of selected precoding weights to a set of antennas to transmit signals to the one or more user devices. Selecting a set of precoding weights may further include calculating, by the access point, the set of precoding weights for each of a plurality of beamformed signals; determining, by the access point, that the set of precoding weights for the plurality of beamformed signals, when applied to a set of antennas for transmitting signals to the one or more user devices, will violate a power constraint; determining, by the access point, that a first set of precoding weights for a first beamformed signal causes a power contribution that is greater than power contributions due to sets of precoding weights of the other beamformed signals; adjusting, by the access point, one or more precoding weights of the first set of precoding weights for the first beamformed signal such that the power constraint will not be violated when the access point applies the precoding weights, including the adjusted first set of precoding weights, to a set of antennas and transmits signals to the plurality of user devices.

    Abstract: There is provided a method, including acquiring, by a network node of a source cell, information that a handover of a plurality user terminals currently connected to the source cell is needed to a target cell; determining at least one attribute with respect to each of the plurality of user terminals; selecting at least some of the plurality of user terminals to form a group of user terminals such that the user terminals in the group share at least one common attribute; and indicating the at least one common attribute of the group to a target node of the target cell in a group handover request message.
