Patent number: 9681414Abstract: A wireless terminal (30) capable of operating in a discontinuous mode and method for operation facilitate measurements pertaining to position of the wireless terminal (30). A measurement request message from a radio access network (28) indicates that measurements are to be performed by the wireless terminal on downlink signals transmitted by the base station or by the base station on downlink signals transmitted by the base station. As a result of or after receiving the message, operation of the wireless terminal (30) changes from a discontinuous mode to a modified mode to facilitate performance of the measurements. Relative to the discontinuous mode at least one of following are shortened or eliminated in the modified mode: (i) the non-reception periods, and (ii) the non-transmission periods.Type: GrantFiled: August 19, 2015Date of Patent: June 13, 2017Assignee: Optis Wireless Technology, LLCInventors: Muhammad Kazmi, Bengt Lindoff, Walter Muller
