20110171988 | METHOD AND APPARATUS FOR TRANSMITTING INFORMATION ABOUT AVAILABLE POWER OF TERMINAL IN MOBILE COMMUNICATION SYSTEM - A method for transmitting power headroom information by a terminal in a mobile communication system, in which power headroom information is generated and transmitted if a change in power headroom is greater than or equal to a predetermined threshold and a total amount of data stored in a buffer of the terminal is greater than or equal to a predetermined threshold. | 07-14-2011 |
20130077587 | METHOD AND APPARATUS FOR TRANSMITTING AND RECEIVING CONTROL CHANNELS BY RESTRICTING A SET OF THE CONTROL CHANNELS IN A WIRELESS COMMUNICATION SYSTEM - A method and apparatus are provided for transmitting control information in a base station for a wireless communication system. The method includes transmitting, to a terminal, information associated with a number of Control Channel Elements (CCEs) included in control channels, determining a set of control channel candidates based on an IDentifier (ID) of the terminal and the information associated with the number of CCEs; selecting at least one control channel candidate from among the set of control channel candidates; and transmitting the control information to the terminal through the selected at least one control channel candidate. | 03-28-2013 |
20140016601 | METHOD AND APPARATUS FOR SCHEDULING ASSIGNMENT OF UPLINK PACKET TRANSMISSION IN MOBILE TELECOMMUNICATION SYSTEM - A method is provided for communication between a UE and a Node B in a communication system. The UE generates a Media Access Control-Protocol Data Unit (MAC-PDU) including a first field related to at least one queue ID and a second field related to at least one amount of data to be transmitted, where the data to be transmitted has its priority. The MAC-PDU including the first and second fields is transmitted to the Node B. Grant information is received from the Node B. Data is transmitted to the Node B based on the grant information and the priority. One amount of data in the second field corresponds to one queue ID in the first field. | 01-16-2014 |
20140254527 | METHOD AND APPARATUS FOR TRANSMITTING INFORMATION ABOUT AVAILABLE POWER OF TERMINAL IN MOBILE COMMUNICATION SYSTEM - A method and apparatus are provided for transmitting power headroom information by a terminal in a mobile communication system. The method includes obtaining, by the terminal, an uplink transmission resource; obtaining, by the terminal, a path loss; and if the path loss is changed more than a threshold since a last transmission of a power headroom, obtaining power headroom information using a maximum transmission output of the terminal and a transmission power of the terminal, and transmitting the power headroom information using the uplink transmission resource. | 09-11-2014 |
20140269639 | METHOD AND APPARATUS FOR TRANSMITTING/RECEIVING DATA AND CONTROL INFORMATION THROUGH AN UPLINK IN A WIRELESS COMMUNICATION SYSTEM - An apparatus and method are provided for transmitting data and control information in a wireless communication system. The method include determining if the control information is to be transmitted via a data channel; and if the control information is to be transmitted in the data channel, determining a number of symbols for coded control information in consideration of the data, generating the coded control information based on the number of symbols for the coded control information, generating coded data based on an MCS for the data, multiplexing the coded data and the coded control information, modulating the multiplexed coded control information and coded data by a modulation scheme, performing FT on the modulated coded control information and coded data, performing IFT on the FTed coded control information and coded data based on sub-carrier mapping, and transmitting the IFTed coded control information and coded data via the data channel. | 09-18-2014 |
20140321405 | APPARATUS AND METHOD FOR ALLOCATING RESOURCES IN A SINGLE CARRIER-FREQUENCY DIVISION MULTIPLE ACCESS SYSTEM - Methods and apparatuses are provided for transmitting data in a subframe including two slots in a communication system. Resource allocation information is received at a UE. The UE determines a resource for data transmission based on the resource allocation information, whether hopping is enabled, whether mirroring is enabled, and whether hopping is intra-subframe and inter-subframe hopping or inter-subframe hopping. Data is transmitted via the determined resource from the UE to a Node B | 10-30-2014 |
20140369298 | METHOD AND APPARATUS FOR TRANSMITTING UPLINK CONTROL INFORMATION IN MULTI-CARRIER WIRELESS COMMUNICATION SYSTEM - A method and apparatus are provided for transmitting Uplink Control Information (UCI) on a data channel in a multi-carrier wireless communication system. The method includes channel-coding a UCI with reference to a number of UCI bits available; dividing the channel coded UCI bits into a number of Physical Uplink Shared Channels (PUSCHs); and transmitting the UCI multiplexed with data on the individual PUSCHs. | 12-18-2014 |
20150092726 | METHOD AND APPARATUS FOR TRANSMITTING/RECEIVING DATA AND CONTROL INFORMATION THROUGH AN UPLINK IN A WIRELESS COMMUNICATION SYSTEM - An apparatus and method are provided for transmitting data and control information in a wireless communication system. The method includes determining a number of symbols for control information based on a number of data bits and scheduled resources; generating coded control information based on the number of symbols for the control information; generating coded data based on a modulation scheme; multiplexing the coded data and the coded control information; modulating the multiplexed coded control information and coded data by the modulation scheme; and transmitting the modulated coded control information and coded data on a channel based on the scheduled resources. | 04-02-2015 |
