Abstract:
The present invention provides an uplink signal transmission method and apparatus. A method for transmitting an uplink signal to an access point (AP) by means of a station (STA) in a Wireless local area network (WLAN) system comprises: sensing a medium being occupied by another STA; and transmitting the uplink signal to the AP on the medium being occupied by another STA.
Abstract:
The present invention relates to a method in which a signal is transmitted between a base station and a terminal in a multi-antenna wireless communication system. The method transmits pre-estimated channel information to the terminal when the terminal moves to a specific position when channel estimation for a specific position is performed. As for the terminal which moves along a fixed route or the route of which can be estimated, the position of the terminal in the near future can be easily detected. Therefore, the transception of channel information can be performed in a more efficient manner in consideration of the above-described special environment.
Abstract:
A device for transmitting and receiving multi-input multi-output (MIMO) signal in a wireless communication system in which a plurality of communication systems is present includes a plurality of antenna modules and a recognition module for recognizing at least one of network information or antenna information of a source device. The recognition module compares a measurement result of the plurality of antenna modules with pre-stored information to recognize the network information or antenna information of the source device.

Abstract:
An embodiment of the present invention relates to a method of obtaining control information through an enhanced physical downlink control channel (E-PDCCH) by a terminal in a wireless communication system. The method includes performing blind decoding on a common searching space in a set of first resource blocks on a subframe; and performing blind decoding on a terminal-specific searching space in a set of second resource blocks on the subframe, wherein a first start orthogonal frequency division multiplexing (OFDM) symbol of an E-PDCCH resource region including the common searching space in the set of first resource blocks and a second start OFDM symbol of an E-PDCCH resource region including the terminal-specific searching space in the set of second resource blocks are set individually.
Abstract:
A method and apparatus for transmitting and receiving uplink control information (UCI) in a radio access system supporting an enhanced physical downlink control channel (e-PDCCH) is disclosed. The method includes transmitting downlink control information (DCI) including offset information for determining resources for transmitting a physical uplink control channel (PUCCH) via the e-PDCCH, and receiving the UCI using uplink resources according to a resource index value for transmitting the PUCCH. The resource index value is calculated using an index value of a control channel element (CCE) comprising the e-PDCCH and the offset information.
Abstract:
Disclosed is a method for allowing a machine type communication (MTC) terminal to transmit and receive a signal in a wireless communication system. A method for allowing an MTC terminal to transmit and receive a signal comprises the steps of: receiving, from a base station, a parameter related to active subframe information for said MTC terminal; obtaining information on active subframe allocated to said MTC terminal by using said received parameter; and transmitting a signal to said base station or receiving a signal from said base station through at least one active subframe on the basis of said obtained information on the active subframes.
Abstract:
An apparatus for boosting an MIMO (multi-input multi-out-put) signal and method thereof are disclosed. The present invention includes determining an initial transmit power value of the signal booster and applying an initial transmit power increment/decrement value to a sum of the initial transmit power value and the initial transmit power increment/decrement value in each preset time interval during an initial power control period.
Abstract:
One embodiment of the present invention relates to a method for acquiring control information, comprising: a step of receiving a plurality of first sequential indexes associated with a resource region via which downlink control information is transmitted; a step of determining a plurality of second indexes from the plurality of first indexes; and a step of determining control channel elements in the order of the resource regions according to the plurality of second indexes, and performing blind decoding wherein the determination o the plurality of second indexes is dependent on a transmission mode and/or downlink control information.
