There is provided mechanisms for beamformed transmission towards groups of terminal devices. Each terminal device is, according to a bandwidth part (BWP) configuration, configured with a BWP set. One BWP in the BWP set is an active BWP for the terminal device. The method is performed by a network node. The method comprises configuring a new terminal device entering one of the groups with an active BWP based on frequency overlap avoidance with the active BWPs of the terminal devices already part of the group entered. The method comprises serving all terminal devices by performing beamformed transmission towards the terminal devices in accordance with the active BWPs.

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first node may determine a grid allocation of single carrier resource blocks (SC-RBs) that defines a plurality of SC-RBs in a time domain and in a frequency domain. The first node may perform, to a second node, a frequency division multiplexed transmission associated with a single carrier waveform using one or more SC-RBs indicated in the grid allocation of SC-RBs. Numerous other aspects are described.

The present invention is designed so that it is possible to reduce the measurement-induced increase of load and power consumption in user terminals even when the number of component carriers that can be configured per user terminal is expanded. A user terminal communicates with a radio base station that configures groups (TAGs) comprised of one or more cells, and has a receiving section that receives information related to component carriers (CCs) included in the groups, and a measurement section that makes measurements on a per group basis based on the information related to the component carriers.

The present invention is designed such that it is possible to optimize the effect of improving the efficiency of use of radio resources even when the number of user terminals to be multiplexed over the same radio resources is further increased. A user terminal performs downlink communication with a radio base station using a PDCCH resource region and a PDSCH resource region. The user terminal detects the starting position of the radio resources where the PDSCH and the PDCCH are frequency-division-multiplexed in the PDSCH resource region in the time direction, and receives the PDCCH that is frequency-division-multiplexed over the radio resources starting from the detected starting position.
