Patent ID: 8553563

Claim:
A method for a wireless device to store measurements of neighboring cells in a mobile communication network, the method comprising: processing, at the wireless device, configuration information for periodic downlink pilot measurements to be stored by the wireless device, the configuration information having an upper limit on a number of neighbor cells for which periodic downlink pilot measurements are permitted to be stored and reported, wherein the upper limit is a first upper limit on a first number of neighbor cells, among all absolute priority layers having higher priority than an absolute priority layer of a serving cell of the wireless device, for which periodic downlink pilot measurements are permitted to be reported, and wherein the configuration information is further associated with: a second upper limit on a second number of neighbor cells, among all absolute priority layers having lower priority than the absolute priority layer of the serving cell of the wireless device, for which periodic downlink pilot measurements are permitted to be reported; and a third upper limit on a third number of neighbor cells, among all absolute priority layers having priority equal to the absolute priority layer of the serving cell of the wireless device, for which periodic downlink pilot measurements are permitted to be reported; and storing, at the wireless device, the periodic downlink pilot measurements in accordance with the configuration information.
