Abstract:
One embodiment of the present invention relates to a method for user equipment transmitting an uplink receipt confirmation reply in a wireless communication system, comprising the steps of: receiving a downlink signal from subframe n; and transmitting a receipt confirmation reply with respect to the downlink signal from the kth subframe from the subframe from which the downlink signal is received, wherein resource for the receipt confirmation reply from the kth subframe is allocated with priority for subframes in a first group common to downlink subframes required to transmit the receipt confirmation reply from the kth subframe according to a first timeline, and downlink subframes required to transmit the receipt confirmation reply from the kth subframe according to a second timeline.
Abstract:
The present invention relates to a method and an apparatus which enable a terminal to transmit a signal for device-to-device (D2D) communication in a wireless communication system. Specifically, the present invention transmits a synchronization signal for D2D communication and a demodulation reference signal (DM-RS) for demodulation of the synchronization signal, wherein the base sequence of the demodulation reference signal is generated using a synchronization reference ID.

Abstract:
An embodiment of the present invention provides a method for a first UE to transmit a physical sidelink shared channel (PSSCH) in a wireless communication system, the PSSCH transmission method comprising: a step of excluding subframes, used by a second UE, from candidate subframes for PSSCH transmission; and a step of selecting a subframe for transmitting a PSSCH and transmitting the PSSCH, after excluding the subframes, used by the second UE, from the candidate subframes, wherein the subframes used by the second UE include subframes assumed to be repeatedly used by the second UE according to a reservation period of the second UE, wherein, if the reservation period of the second UE is smaller in value than a predetermined value, the shorter the reservation period of the second UE becomes, the greater the number of the subframes assumed to be repeatedly used becomes.
Abstract:
An embodiment of the present invention provides a device-to-device (D2D) signal transmission method wherein a terminal acquires synchronization and transmits a D2D signal by applying an offset in a wireless communication system, the method comprising the steps of: acquiring synchronization from at least one of a global navigation satellite system (GNSS) and an eNB; and transmitting a D2D signal on the basis of the acquired synchronization, wherein, when the terminal a) is located within a time division duplex (TDD) cell and b) is an in-coverage UE, and c) the eNB configures a system frame number (SFN) boundary on the basis of GNSS timing, the terminal applies a predetermined offset when a D2D signal is transmitted, regardless of whether the GNSS is used as a synchronization reference.
Abstract:
A method by which a first device performs wireless communication and a device for supporting same are provided. The method can comprise the steps of: transmitting a random access preamble to a base station; receiving, from the base station, a random access response message related to the random access preamble; transmitting, to the base station, a radio resource control (RRC) setup request message on the basis of the random access response message; receiving, from the base station, an RRC setup message as a response to the RRC setup request message; and receiving, from the base station, an RRC message including a setup related to a Uu bandwidth part (BWP) and a setup related to a sidelink (SL) BWP, wherein first device cannot perform SL communication through the SL BWP on the basis of the fact that the numerology of the Uu BWP and the numerology of the SL BWP are different.
Abstract:
One embodiment of the present invention relates to a method for a reader to transmit and receive a signal to and from a tag, the method comprising: a step in which a first reader transmits a first signal to a tag; and a step in which the first reader receives the first signal reflected on the tag. The timing for the first reader to transmit the first signal is determined by using an offset value based on an ID related to the first reader.
