20140098719 | METHOD AND APPARATUS FOR PERFORMING HARQ PROCESS IN WIRELESS COMMUNICATION SYSTEM - A method and an apparatus for performing hybrid automatic repeat request (HARQ) in a wireless communication system is provided. UEs that use the same application for D2D communications form a sharing group so that reliability of transmission of a physical uplink shared channel (PUSCH) and a physical uplink control channel (PUCCH) among terminals that perform the D2D communications is guaranteed. In addition, among the terminals that perform the D2D communications, uplink transmission points in time determined in accordance with TDD configuration are checked and determined (calculated) so that the PUSCH and the PUCCH are correctly transmitted and received. | 04-10-2014 |
20130322323 | METHOD AND DEVICE FOR AVOIDING INTER-CELL INTERFERENCE IN A WIRELESS ACCESS SYSTEM - According to the present invention, a method for a relay node (RN) to reallocate a resource in order to avoid inter-cell interference (ICI) in a wireless access system includes: overhearing a control channel including downlink or uplink resource allocation information transmitted by a plurality of base stations to terminals in the coverage area of each base station; sharing the RN by means of the plurality of base stations; confirming that there is a resource area in which conflicts are occurring by comparing resource areas allocated to terminals in the coverage area of the RN through the control channel; and, if it is determined, on the basis of the confirmation result, that there is a resource area in which conflicts are occurring, reallocating a resource to the resource area in which conflicts are occurring. | 12-05-2013 |
20130315193 | METHOD FOR AVOIDING INTER-CELL INTERFERENCE IN A WIRELESS ACCESS SYSTEM - A method for a relay node (RN) to avoid inter-cell interference (ICI) in a wireless access system is provided. The method includes: overhearing a PDCCH transmitted by a plurality of BSs sharing the RN to terminals of each BS in the nth subframe; decoding the PDCCH from the n+1th subframe to the n+2th subframe; reallocating resource area to the terminals; transmitting control information representing the reallocated resource area to each BS; overhearing and decoding a PUSCH to each BS in the n+4th subframe; transmitting the decoding result to each BS; overhearing a PDCCH updated at n+8th subframe; and retransmitting the PUSCH transmitted at the n+4th subframe to a BS(NACK) in the n+12th sub frame. | 11-28-2013 |
20130242855 | METHOD FOR AVOIDING INTER-CELL INTERFERENCE IN WIRELESS ACCESS SYSTEM - According to the disclosure of the present invention, provided is a method for operating a relay node (RN) to avoid an inter-cell interference (ICI) in a wireless access system. The method includes: overhearing the downlink signal transmitted by a plurality of base stations to terminals within the coverage area of each base station in an n | 09-19-2013 |
