20090262848 | METHOD OF DESIGNING A MULTIPLEXING STRUCTURE FOR RESOURCE ALLOCATION TO SUPPORT LEGACY SYSTEM - New multiplexing UL structures for supporting legacy system are provided. A 16m system of diversity mode can be multiplexed with 16e system in PUSC mode in FDM manner with the same tiles/permutation rules. A 16m system can be multiplexed with 16e system in AMC mode in FDM and/or TDM manner. The time length of multiplexed 16e PUSC packets and/or 16m packets can be extended to more than two sub-frames for UL coverage. A PRU for 16m system may consists of 16 sub-carriers by 6 OFDMA symbols, 18 sub-carriers by 6 OFDMA symbols, or 20 sub-carriers by 6 OFDMA symbols when FDM is used. | 10-22-2009 |
20100238875 | METHOD FOR TRANSMITTING VOIP PACKET - A method for transmitting a voice over Internet protocol (VoIP) packet includes allocating a radio resource for VoIP packet transmission to a user, transitioning a VoIP service from a talk period, in which the VoIP packet is transmitted using the radio resource, to a silence period in which the VoIP packet is not transmitted, releasing the radio resource during the silence period, and transitioning the VoIP service to the talk period by reallocating the radio resource. Limited radio resources can be further effectively used. | 09-23-2010 |

20110014909 | METHOD OF TRANSMITTING INTERFERENCE INFORMATION SIGNAL IN WIRELESS COMMUNICATION SYSTEM - A method of transmitting an interference information signal in a wireless communication system is provided. The method includes receiving a neighbor sounding signal from a mobile station (MS) in a neighbor cell, obtaining an interference information signal based on the neighbor sounding signal and transmitting the interference information signal to a neighbor base station (BS), the neighbor BS which is a BS in the neighbor cell. | 01-20-2011 |
20110051668 | METHOD FOR TRANSMITTING AND RECEIVING PAGING INFORMATION IN A BROADBAND WIRELESS ACCESS SYSTEM - A method for efficiently transmitting and receiving a paging message and system information from and in a mobile station of a broadband wireless access system is disclosed. A method for receiving a paging message in a mobile station comprise receiving paging information from a serving base station, the paging information including paging sub group identifier (paging sub_group ID) indicating a paging sub group to which the mobile station belongs; and receiving the paging message for a predetermined paging interval of the paging sub group, wherein the paging sub group is determined separately from a paging group and a geographical location determining the paging group, and is maintained while the mobile station is being operated in an idle mode. | 03-03-2011 |
20110317619 | METHOD AND APPARATUS FOR RELAYING DATA IN WIRELESS COMMUNICATION SYSTEM - A method and apparatus of relaying data in a wireless communication system is provided. A relay station (RS) receives relay zone allocation information. A plurality of relay zones is allocated in a resource region by the relay zone allocation information. The relay station receives data transmitted from a super-ordinate station, detects a tunneling traffic destined to a subordinate station from the data, and transmits the tunneling traffic to the subordinate station. The tunneling traffic is transmitted over one of the plurality of relay zones. | 12-29-2011 |
20130139020 | METHOD OF TRANSMITTING DATA USING CONSTELLATION REARRANGEMENT - A data retransmission method using hybrid automatic repeat request (harq) includes transmitting a data block, receiving a retransmission request signal for the data block, generating a retransmission block by performing swapping or inversion between bits constituting the data block according to the retransmission request signal, and transmitting the retransmission block. | 05-30-2013 |
20140192720 | METHOD FOR TRANSMITTING AND RECEIVING PAGING INFORMATION IN A BROADBAND WIRELESS ACCESS SYSTEM - A method for efficiently transmitting and receiving a paging message and system information from and in a mobile station of a broadband wireless access system is disclosed. A method for receiving a paging message in a mobile station comprises receiving paging information from a serving base station, the paging information including paging sub group identifier (paging sub group ID) indicating a paging sub group to which the mobile station belongs; and receiving the paging message for a predetermined paging interval of the paging sub group, wherein the paging sub group is determined separately from a paging group and a geographical location determining the paging group, and is maintained while the mobile station is being operated in an idle mode. | 07-10-2014 |
