Abstract:
A beamforming training using a polarization in a wireless local area network is provided. An initiator receives a response frame from the responder. The response frame includes information about a polarization type selected by the responder. The initiator transmits a sector sweep message to the responder using the selected polarization type through all sectors during a sector sweep.

Abstract:
Disclosed are a terminal device for controlling uplink signal transmission power, and a method therefore. The present invention relates to a method and terminal device for controlling uplink transmission power, wherein the method, in which a terminal that communicates with cells of each timing alignment (TA) group controls uplink transmission power in the event a plurality of TA groups including one or more cells exists in a wireless communication system, comprises: a step of determining the uplink transmission power for at least one channel in the event at least two channels from among a physical uplink control channel (PUCCH), a physical uplink shared channel (PUSCH) including a plurality of pieces of uplink control information (UCI), a PUSCH including no UCI, a physical random access channel (PRACH), and a sounding reference signal (SRS) are simultaneously transmitted in the same subframe in each specific cell of the plurality of TA groups; and a step of transmitting said at least one channel with the determined uplink transmission power, wherein said uplink transmission power is determined in consideration of a TA group index.
Abstract:
The present invention relates to a Method for a device-to-device (D2D) communication in a wireless communication system. Specifically, when a terminal, which is performing a device-to-device communication while performing channel hopping, additionally performs the device-to-device communication with a new terminal, a channel hopping period of the existing device to device communication is configured by same time intervals for channels and one time interval among the same time intervals is configured to be identical to a channel hopping period for discovering a new terminal.
Abstract:
An embodiment of the present invention provides a method for receiving a signal from an access point (AP) by a station (STA) in a wireless communication system, the method comprising the steps of: receiving a raw parameter set (RPS) element including a restricted access window (RAW) allocation field; and identifying, in the RAW allocation field, first information indicating whether the RAW allocation field relates to a periodic RAW and second information indicating whether the RAW allocation field relates to AP power management (PM), wherein the STA can acquire only information relating to a time interval of the RAW in subfields other than a subfield including the first information and the second information when the RAW relates to the AP PM.
Abstract:
The D2D communication method may comprise the step of: transmitting, by a search device, a search request message through each of a plurality of channels in a search area, the search area corresponding to time resource allocated to integer multiple slots; receiving, by the search device, a search response message as a response to the search request message from a device found through at least one channel from among the plurality of channels in the search area, the search response message containing slot timing information and information on a first channel hopping pattern; synchronizing with the found device based on the slot timing information in a peering area by the search device; and performing communication with the found device, by the search device, on the basis of the information on the first channel hopping pattern in a communication area.
Abstract:
The present invention relates to a method for performing communication between terminals (D2D). Specifically, the method is characterized in that when a terminal communicating with another terminal is to perform an additional communication with yet another terminal, the channel sequence of the communicating terminal is determined, and one of the two terminals communicating with each other is defined as the channel synchronization reference terminal performing synchronization.
Abstract:
One embodiment of the present invention relates to a method for transmitting/receiving information related to an association identification (AID) in a wireless communication system, the transmitting/receiving method comprising: a step in which a second STA having a direct link to a first STA receives an announcement frame related to an updated AID from the first STA; and a step in which the second STA transmits an ACK frame in response to the announcement frame, wherein the announcement frame comprises one or more AID-MAC address pairs and the second STA updates the AID of an STA corresponding to the one or more AID-MAC address pairs.
