Abstract: A cellular communication system comprising a plurality of user equipment and a network infrastructure. Radio resource of the plurality of cells is divided into more than one radio resource groups. A network infrastructure element detects a requirement of radio resource allocation for a user equipment and determines effective interference to be generated by the required radio resource to a defined group of neighboring cells. User equipment is allocated a radio resource from one of the radio resource groups on the basis of the determined effective interference to be generated to the defined group of neighboring cells. Inter-cell interference decreases and the throughput of the cellular system increases, but the exchange of physical layer information is not increased.

Abstract: Various communication systems may benefit from improved signaling. For example, anew radio communication system may benefit from a flexible indication of transmission timing. A method may include determining, at the user equipment, transmission timing based on a first parameter and a second parameter. The first parameter may indicate an offset as a number of slots. The second parameter may indicate an offset as a number of symbols within one of the slots. The method may also include using the transmission timing to at least one of send an uplink transmission or receive a downlink transmission.
