A method performed in a User Equipment, UE, located in a serving cell operated by an eNodeB of an Evolved Universal Terrestrial Radio Access Network, E-UTRAN, the method comprising: - receiving a request from the eNodeB to report system information of a second cell, and in response to the request, the method further comprising: - determining that the UE is configured with a flexible subframe allocation scheme in the serving cell during at least a part of a time period, the method characterized in comprising: - retrieving a value Nmin stored in the UE, the value Nmin being associated with the flexible subframe allocation scheme configuration and corresponding to a serving cell performance requirement on a minimum number of uplink feedback signals to send in response to continuous downlink data received in the serving cell during the time period, - acquiring system information of the second cell using at least one autonomous gap during the time period, while fulfilling the serving cell performance requirement, - transmitting the acquired system information of the second cell to the eNodeB. - receiving a request from the eNodeB to report system information of a second cell, and in response to the request, the method further comprising: - determining that the UE is configured with a flexible subframe allocation scheme in the serving cell during at least a part of a time period, the method characterized in comprising: - retrieving a value Nmin stored in the UE, the value Nmin being associated with the flexible subframe allocation scheme configuration and corresponding to a serving cell performance requirement on a minimum number of uplink feedback signals to send in response to continuous downlink data received in the serving cell during the time period, - acquiring system information of the second cell using at least one autonomous gap during the time period, while fulfilling the serving cell performance requirement, - transmitting the acquired system information of the second cell to the eNodeB. - determining that the UE is configured with a flexible subframe allocation scheme in the serving cell during at least a part of a time period, the method characterized in comprising: - retrieving a value Nmin stored in the UE, the value Nmin being associated with the flexible subframe allocation scheme configuration and corresponding to a serving cell performance requirement on a minimum number of uplink feedback signals to send in response to continuous downlink data received in the serving cell during the time period, - acquiring system information of the second cell using at least one autonomous gap during the time period, while fulfilling the serving cell performance requirement, - transmitting the acquired system information of the second cell to the eNodeB. - retrieving a value Nmin stored in the UE, the value Nmin being associated with the flexible subframe allocation scheme configuration and corresponding to a serving cell performance requirement on a minimum number of uplink feedback signals to send in response to continuous downlink data received in the serving cell during the time period, - acquiring system information of the second cell using at least one autonomous gap during the time period, while fulfilling the serving cell performance requirement, - transmitting the acquired system information of the second cell to the eNodeB.
