Abstract: A method of and User Equipment (UE) for enhancing reporting information for a Radio Link Failure (RLF) in a Long Term Evolution (LTE) network. The method includes receiving, by a User Equipment (UE), RLF threshold information transmitted from the LTE network, logging, by the UE, the RLF threshold information, and indicating, by the UE, a recovery from a near RLF condition. The UE includes at least one means adapted for receiving an RLF threshold information transmitted from the network; logging the RLF threshold information; and indicating to the LTE network a recovery from a near RLF condition based on the RLF threshold information.

Abstract: An apparatus and method are provided for reducing power consumption in a user equipment (UE). The method includes establishing, by the UE, a connection with a network; receiving, by the UE, from the network, system information of at least one of a resident cell and a neighboring cell indicating if a network feature is supported by the at least one of the resident cell and the neighboring cell; determining, by the UE, if a selection criteria of a cell from among the at least one of the resident cell and the neighboring cell, which supports the network feature, is greater than a threshold; reselecting the cell having the selection criteria that is greater than the threshold; and initiating a connection establishment with the reselected cell, which supports the network feature.

Abstract: A system and method are provided for reducing signaling overhead in a wireless communication system. The method includes establishing device-to-device communication between a first User Equipment (UE1) and a second User Equipment (UE2) over a locally routed data path; sending, by the UE1, a signal quality measurement report to a network; identifying, by the network, that the UE1 is locally routed for proximity services with the UE2; applying, by the network, cell biasing to a serving cell for at least one of the UE1 or the UE2; verifying, after the cell biasing, whether the at least one of the UE1 or the UE2 sustains a connection with the serving cell; and continuing the proximity services through the locally routed data path, if the at least one of the UE1 or the UE2 sustains the connection with the serving cell.

Abstract: A method and system for providing memory management in a Real-Time Operating System (RTOS) based system are provided. The method includes creating a plurality of tasks with a two level stack scheme comprising a first level stack and a second level stack, scheduling a first task for execution by moving a stack pointer from the first level stack to the second level stack, determining whether the first task is pre-empted, allocating the second level stack to the first task in a second state if the first task is not pre-empted, changing an active task for execution, determining whether the first task relinquishes control from the second state and is waiting for a resource, moving the stack pointer back from the second level stack to the first level stack if the first task relinquishes itself and providing the second level stack for use by a second task.
