Improving operation of beam-based wireless communication networks

A method, comprising:

• configuring a receiver for monitoring at least one first downlink control channel associated with at least one first downlink beam of a beamformed transmission according to a first offset corresponding to an OnDuration;
• receiving a first command for changing from the at least one first downlink beam to at least one second downlink beam;
• and
• configuring, in response to receiving the first command, the receiver for monitoring the at least one first downlink control channel associated with the at least one second downlink beam according to a second offset corresponding to an OnDuration,
• wherein the first offset corresponding to an OnDuration comprises a first starting time, duration and periodicity for monitoring the at least one first downlink control channel and the second offset corresponding to an OnDuration comprises a second starting time, duration and periodicity for monitoring the at least one first downlink control channel, and
• wherein the first offset corresponding to an OnDuration is associated with a first TCI (Transmission Configuration Indication) state and the second offset corresponding to an OnDuration is associated with a second TCI state.

An apparatus comprising at least one processing core, at least one memory including computer program code, the at least one memory and the computer program code being configured to, with the at least one processing core, cause the apparatus at least to perform:

• configure a receiver for monitoring at least one first downlink control channel associated with at least one first downlink beam of a beamformed transmission according to a first offset corresponding to an OnDuration;
• receive a first command for changing from the at least one first downlink beam to at least one second downlink beam;
• and
• configure, in response to receiving the first command, the receiver for monitoring the at least one first downlink control channel associated with the at least one second downlink beam according to a second offset corresponding to an OnDuration,
• wherein the first offset corresponding to an OnDuration comprises a first starting time, duration and periodicity for monitoring the at least one first downlink control channel and the second offset corresponding to an OnDuration comprises a second starting time, duration and periodicity for monitoring the at least one first downlink control channel, and
• wherein the first offset corresponding to an OnDuration is associated with a first TCI (Transmission Configuration Indication) state and the second offset corresponding to an OnDuration is associated with a second TCI state.
