Abstract: Provided is a method and device for correcting an error in a communication system, the method including: transmitting, to another device, data encrypted based on key information. The key information is obtained by: incident a detection pulse on a variable Faraday rotating mirror and a reference pulse on a first mirror, respectively, wherein the detection pulse and the reference pulse are pulses branched from a test pulse; generating a first current in a balanced photodetector (BPD) based on a first component obtained as the detection pulse is reflected from the variable Faraday rotating mirror and a second component obtained as the reference pulse is reflected from the first mirror; converting the first current into a second current; incident the second current on the variable Faraday rotating mirror; and correcting the error in the variable Faraday rotating mirror based on the incident second current.

Abstract: The present specification suggests a method and an apparatus for more efficient mobility management through a hierarchical structure of a micro mobility management entity (MME) and a macro MME in a mobile communication system. Particularly, a second MME establishes a connection with a plurality of small cells included in a single macro cell. The second MME manages a single particular macro cell, and a first MME manages a plurality of macro cells, thereby providing a hierarchical structure. Additionally, the second MME transmits a paging message to a small cell in which a terminal is positioned, among the plurality of small cells included in a single macro cell. The second MME has information on the position of the terminal and can transmit the paging message to a particular small cell in which the terminal is positioned.

Abstract: A method and apparatus for confirmation of multiple configured grants for sidelink in a wireless communication system is provided. A wireless device receives activation command or deactivation command on Physical Downlink Control Channel (PDCCH) for at least one of the multiple configured grants. A wireless device receives transmits, to the network, a confirmation Media Access Control (MAC) Control Element (CE). The confirmation MAC CE includes one or more fields in a bit group of which size is equal to number of the multiple configured grants. Each field in the bit group is set to (i) zero to indicate deactivation for each of the multiple configured grants or (ii) 1 to indicate activation for each of the multiple configured grants. Each field in the confirmation MAC CE except the bit group is ignored.

Abstract: The present specification suggests a method for improving performance degradation caused by frequent handovers when a terminal moves among several cells, particularly among dense small cells. To this end, required are cooperative transmission among cells and a new handover method. A base station receives RSRP information about an anchor cell and a neighboring cell and configures a cooperation-based cell cluster using the RSRP information. If RSRP values are compared and meet specific conditions, the anchor cell and the neighboring cell carry out cooperative communication. If the RSRP values of the anchor cell and an anchor candidate cell are compared during the cooperative communication and meet specific conditions, handover from the anchor cell to the anchor candidate cell is carried out. If the present invention is applied, when the terminal moves in an environment where small cells are dense, the number of handovers is greatly reduced and thus network burden can be lessened.

Abstract: The present specification suggests a method for establishing a terminal-centric group cell on the basis of measurement signal variation for cooperative transmission and handover in a mobile communication system. Specifically, a base station receives transmissions of parameters from a terminal, configures a terminal surrounding cell information table, and configures a cooperative cell cluster configuration table using the terminal surrounding cell information table as the terminal moves. The base station performs cooperative transmission and handover using the cooperative cell cluster configuration table. The terminal sends parameters to the base station periodically or when a certain condition is met, and the base station updates the terminal surrounding cell information table and the cooperative cell cluster configuration table using the parameters sent from the terminal to thereby use the same for mobility management.
