Abstract
Techniques for minimizing the loss of radio signals transmitted on and/or received from serving cells in a multi-carrier system by selectively adapting the time instance at which a wireless terminal: (1) changes its radio frequency (RF) bandwidth or activates a second RF chain or any additional RF chain for measuring on one or more secondary serving cells, and/or (2) performs setup or release of one or more secondary serving cells. An example method, implemented in a radio network node, comprises determining (510) a scheduling instance during which a wireless terminal is expected to be scheduled on at least one cell; and, determining (520) a timing at which to send a setup or release command for at least one secondary cell such that the requested set up or release procedure does not coincide with the scheduling instance.
