    Abstract: A base station, a wireless device and methods therein for supporting radio communication, wherein the base station employs carrier aggregation with multiple carriers serving a primary cell, PCell, and at least one secondary cell, SCell. The base station signals (3:3) an SCell status to the wireless device, the SCell status indicating whether the at least one SCell will be in active state where the base station transmits downlink signals on a carrier serving the at least one SCell, or in inactive state where the base station does not transmit downlink signals on the carrier serving the at least one SCell. Thereby, the wireless device can adapt its behaviour depending on the signalled SCell status, e.g. by turning off its receiver and not perform any signal measurements when the SCell is in inactive state.

  • Using an uplink grant as trigger of first or second type of CQI report
    Patent number: 12167417
    Abstract: Channel state feedback is provided from a UE to a base station as a first, detailed or a second, less detailed type of channel state feedback information. Initially it is determined whether the UE has received an uplink grant from the base station or not. If the UE has received an uplink grant, a first type of channel state feedback information is transmitted to the base station on the granted resource. If, however, the UE has not received an uplink grant, a second type of channel state feedback information is transmitted to the base station. Different types of channel state feedback information enables a UE and an associated base station to use available resources more efficiently, when requesting for and delivering channel state feedback information.
