20140362796 | METHOD AND APPARATUS FOR ALLOCATING CHANNELS RELATED TO UPLINK BUNDLING - A new PHICH channel and a new PDCCH channel are allocated when the location of a subframe to be used in transmission changes by the change in the configuration of the subframe caused by a dynamic uplink/downlink configuration in a subframe bundling transmission mode. In the event that a subframe is successfully transmitted in a subframe bundling mode, the location of the subframe that has been successfully transmitted is determined as a reference in determining the point of time of the response to the bundling transmission. In addition, the bundling transmission following the subframe that has been successfully transmitted can be omitted. | 12-11-2014 |
20150063231 | METHOD FOR RECEIVING DOWNLINK CONTROL SIGNAL, USER EQUIPMENT, METHOD FOR TRANSMITTING DOWNLINK CONTROL SIGNAL AND BASE STATION - In the event where a channel strength between UE and eNB is weakened, the eNB of the present invention may configure downlink control information into the format in which at least one of fields of pre-defined existing format is deleted, the length of a relevant field is shortened to be shorter than a pre-defined length of the relevant field, or an error correcting code is added by the amount of the length deleted or reduced. UE decodes a downlink signal according to the modified format to acquire downlink control information of its own. | 03-05-2015 |
20150078270 | METHOD FOR TRANSMITTING AND RECEIVING CONTROL INFORMATION AND APPARATUS FOR SAME - Specifically, in one aspect of the present invention, a method and apparatus for controlling transmitting power by a terminal in a wireless communication system that supports device to device (D2D) communication include: receiving a power control command through a control channel from a base station; and adjusting transmitting power according to the power control command, wherein when the terminal performs D2D communication, the power control command indicates one of a first set of power control values having more states assigned to lower the transmitting power, and when the terminal performs communication with the base station, the power control command indicates one of a second set of power control values having more states assigned to raise the transmitting power. | 03-19-2015 |
20150131566 | SIGNAL TRANSMISSION/RECEPTION METHOD AND APPARATUS THEREFOR - The present invention relates to a wireless communication system. More particularly, the present invention relates to a method by which a terminal receives a signal in a wireless communication system which supports device-to-device (D2D) communication and an apparatus therefor, the method comprising the steps of: receiving, from a base station, information about a second signal for D2D communication; receiving from the base station, information about a first signal which acts as an interference signal; receiving the second signal along with the first signal from a second terminal; and removing the first signal from the second signal by using the information about the first and the second signal, wherein the information about the second signal includes an indicator for indicating whether the second signal has the same format used in a 3GPP LTE system, and the information about the second signal further includes information about a parameter different from the one that is used in the 3GPP LTE system, if the second signal does not have the same format as used in the 3GPP LTE system. | 05-14-2015 |
20150146642 | METHOD AND DEVICE FOR RETRANSMITTING UPLINK DATA IN WIRELESS COMMUNICATION SYSTEM - The present invention relates to a wireless communication system. Particularly, the present invention provides a method for enabling a user equipment (UE) to retransmit uplink data on the basis of a signal received through a physical hybrid ARQ indicator channel (PHICH) in a wireless communication system and a device for the same, and the method for retransmitting uplink data comprises the steps of: receiving, from a base station, an indication on whether or not to detect the PHICH; retransmitting the uplink data on the basis of a PHICH detection result if the received indication is to detect the PHICH; and retransmitting the uplink data on the basis of an uplink grant received from the base station if the received indication is not to detect the PHICH. | 05-28-2015 |
