COVERAGE ENHANCEMENT AND SEMI-PERSISTENT SCHEDULING SUPPORT IN LTE-TDD SYSTEMS

摘要

Technology for reporting mobility information is disclosed. Mobility information can be identified for the UE when the UE is in idle mode, the mobility information including a visited cell history for the UE when the UE is in idle mode. An evolved node B (eNB) can be notified that the mobility information for the UE is available when the UE transitions from the idle mode to a connected mode. A request can be received from the eNB for the mobility information. The mobility information can be sent to the eNB using a reduced number of bits to represent the mobility information while substantially maintaining a level of accuracy of a mobility state estimation for the UE, wherein the mobility state estimation is performed at the eNB in order to determine an estimated speed of the UE.
