A method of operating a wireless terminal, UE, in a radio access network, RAN, the method comprising: receiving from the RAN a request to report respective cell identifiers of first and second neighbor cells; starting a timer responsive to receiving the request to report the cell identifiers of the first and second neighbor cells, wherein the timer is associated with the first and second neighbor cells; obtaining a first system information from the first neighbor cell responsive to receiving the request, wherein the first system information indicates that the first neighbor cell does not broadcast a cell identifier; obtaining a second system information from the second neighbor cell responsive to receiving the request, wherein the second system information indicates that the second neighbor cell does broadcast a cell identifier; stopping the timer before expiration of the timer responsive to obtaining the system information including the indication that the neighbor cell does not broadcast the cell identifier of the neighbor cell; transmitting a measurement report to the RAN responsive to obtaining the first system information indicating the that first neighbor cell does not broadcast a cell identifier, wherein the measurement report includes respective empty fields for cell identifiers for the first and second neighbor cells, and wherein the measurement report indicates that the first neighbor cell does not broadcast a cell identifier and that the second neighbor cell does broadcast a cell identifier; and aborting acquisition of a cell identifier of the second neighbor cell responsive to obtaining the first system information including the indication that the first neighbor cell does not broadcast a cell identifier. receiving from the RAN a request to report respective cell identifiers of first and second neighbor cells; starting a timer responsive to receiving the request to report the cell identifiers of the first and second neighbor cells, wherein the timer is associated with the first and second neighbor cells; obtaining a first system information from the first neighbor cell responsive to receiving the request, wherein the first system information indicates that the first neighbor cell does not broadcast a cell identifier; obtaining a second system information from the second neighbor cell responsive to receiving the request, wherein the second system information indicates that the second neighbor cell does broadcast a cell identifier; stopping the timer before expiration of the timer responsive to obtaining the system information including the indication that the neighbor cell does not broadcast the cell identifier of the neighbor cell; transmitting a measurement report to the RAN responsive to obtaining the first system information indicating the that first neighbor cell does not broadcast a cell identifier, wherein the measurement report includes respective empty fields for cell identifiers for the first and second neighbor cells, and wherein the measurement report indicates that the first neighbor cell does not broadcast a cell identifier and that the second neighbor cell does broadcast a cell identifier; and aborting acquisition of a cell identifier of the second neighbor cell responsive to obtaining the first system information including the indication that the first neighbor cell does not broadcast a cell identifier.
