Abstract: The present disclosure relates to a terminal and a base station as well as to a method which may be performed at a terminal and at a base station in a communication system. For example, a mobile device may comprise a transceiver, which, in operation, receives and/or transmits a signal, as well as a circuitry. The circuitry monitors a signal in a first set of resources. When the monitored signal includes identification of the mobile device and an indicator having a first value, controls the transceiver: to receive or transmit signal on a second set of resources and to, after a time period indicated in the monitored control signal, not receive or transmit signal on a second set of resources and monitor the control signal in the first set of resources.

Abstract: The present disclosure relates to a user equipment (UE), comprising the following. A processor of the UE operates a monitoring function that involves monitoring of a downlink control channel for receiving a downlink control information message based on one of a plurality of groups of search space sets. A receiver of the UE receives a downlink control information message via the monitored downlink control channel, wherein the received downlink control information message allocates transmission or reception of data to the UE. The processor further determines one group of the plurality of groups of search space sets for performing the monitoring function of the downlink control channel The determining the one group of search space sets is based on the content or the format of the received downlink control information message.

Abstract: The present disclosure relates to a transmission device, a reception device, a transmission method and a reception method. The transmission device comprises a circuitry which, in operation, maps data and/or a reference signal onto a resource unit of a communication system. The resource unit includes subcarriers of a first numerology and subcarriers of a second numerology, each of the subcarriers being orthogonal to the other subcarriers of the same numerology, wherein the first numerology differs from the second numerology at least by a larger subcarrier spacing, and the subcarriers of the first and the second numerologies are frequency-multiplexed on a subcarrier basis. The transmission device further comprises a transmitter which, in operation, transmits the mapped data and/or reference signal in the resource unit, including subcarriers of the first and/or of the second numerology, and also transmits an indication of the mapping for the resource unit, which comprises references to subcarriers from the subcarriers of the first and/or the second numerology, where: for the first numerology, all subcarriers of the resource unit can be referenced, and for the second numerology, only inter-numerology-orthogonal subcarriers thereof can be referenced, each of the inter-numerology-orthogonal subcarriers being centrally aligned with a subcarrier of the first numerology.
