Abstract: A long term evolution (LTE) protocol and a technology for designing an entity of the LTE protocol in layer 2 are provided. The method includes receiving a control message including packet data convergence protocol (PDCP) configuration information from an external communication device, determining whether data of a PDCP protocol data unit (PDU) received by the communication device is compressed according to the received PDCP configuration information, and when the data is compressed based on a result of the determination, decompressing the data.

Abstract: Method and apparatuses are provided for providing preemptive task scheduling for a Real Time Operating System (RTOS). A two-level priority is assigned to each task that is created. The two-level priority includes a kernel priority and a user-defined priority. A priority bitmap corresponding to the kernel priority is created. A priority bit in the priority bitmap is enabled.

Abstract: A method and system for providing power management in a system employing a Central Processing Unit (CPU) and an operating system are provided. The method includes monitoring idle times of the CPU; predicting an idle pattern based on the monitored idle times; and determining a selective sleep of a peripheral device based on the predicted CPU idle pattern.

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.

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: 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 method and system for providing small cell deployment and access in a green 3GPP LTE system are disclosed. The method includes establishing, by a UE, an RRC connection with a macro cell, receiving, by the macro cell, an RRC connection establishment message from the UE, wherein the RRC connection establishment message includes an IE including an identity of a list of small cells on which the UE can initiate a connection, determining by the macro cell, at least one small cell for data transfer, verifying, by the macro, if the at least one small cell is in a sleep mode or not, triggering, by the macro cell, a connection setup message for initiating a connection between the UE and the at least one small cell if the small cell is in a wake up mode, sending, by the UE, an SRS for initial timing alignment and allocating by the at least one small cell, an uplink/downlink resource to the UE for communication with the at least one small cell.

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: A method for generating a symbol in a programming language is provided. The method includes declaring a variable in a header file, generating a first file including an instruction to include the header file and including a function referring to the declared variable, generating a second file including an instruction to include the first file, and compiling the second file.

Abstract: The present invention proposes a mechanism to update/include the MAC Control information elements like PHR and BSR etc which are reported to ENB to schedule, maintain and operate the reporting UE. It also provides methods and means to handle Msg3 formation and reformation when RACH fails on one component carrier and is continued on another in Carrier Aggregation. New triggers for BSR and PHR reporting are provided in this scenario.
