Abstract:
The present invention relates to a wireless communication system and, more particularly, to a method by which a terminal receives an EPDCCH signal in a wireless communication system and a device for the same, the method comprising the steps of receiving a subframe including an EPDCCH set, wherein the EPDCCH set includes a plurality of EPDCCH candidates; and monitoring the plurality of EPDCCH candidates in the EPDCCH set in order to receive the EPDCCH signal, wherein the number of EPDCCH candidates having an aggregation level of L in the EPDCCH set is indicated and is limited to a value of a specific form under a predetermined condition.
Abstract:
The present invention relates to a wireless communication system. In detail, provided are a method by which a terminal receives a control channel signal in a wireless communication system, and an apparatus for same, including the steps of: receiving a subframe including a plurality of control channel sets, wherein each control channel set includes a plurality of control channel candidates; and monitoring at least one control channel set in the subframe for receiving the control channel signal, wherein the plurality of control channel candidates are scrambled by a scrambling sequence having a control channel set-specific initialization value in each control channel set.
Abstract:
A method for allocating resources for a downlink control channel by a base station in a wireless communication system is disclosed. Specifically, the method comprises the steps of: mapping resource elements to resource element groups for each of resource blocks; forming control channel elements by using a predetermined number of resource element groups from among the resource element groups; and allocating control channel elements of a number corresponding to an aggregation level of the downlink control channel as resources for the downlink control channel, wherein the number of available resource elements included in each of the resource element groups or the number of available resource elements included in each of the control channel elements of a number corresponding to the aggregation level is uniform.

Abstract:
In the present invention, disclosed is a method for a base station transmitting a downlink control channel to user equipment in a wireless communication system. More specifically, the method comprises the steps of configuring resource elements, which are included in each of a plurality of resource blocks, as a plurality of resource element groups comprising a predetermined number of resource elements; allocating antenna ports to the resource elements which are included in each of the plurality of resource element groups; allocating as a transmission resource for the downlink control channel, at least one resource element group from each of the plurality of resource blocks; and transmitting the downlink control channel to the user equipment by using the transmission resource.

Abstract:
Disclosed is a method for a base station to transmit a downlink control channel in a wireless communication system. Specifically, the method comprises the steps of: determining, on the basis of the number of usable resource elements in one pair of resource blocks, the size of a resource allocation unit for a downlink control channel and the number of resource allocation units within one pair of resource blocks; mapping the downlink control channel, from a preset number of resource block pairs, to the transmission resource on the basis of the determined resource allocation unit; and transmitting the downlink control channel to a terminal, wherein the size of the resource allocation unit is defined by the number of resource elements and is varied according to the number of usable resource elements.
Abstract:
One embodiment is a method for performing an operation for a terminal in a wireless communication system, the method including: a step for transmitting a first message to one or more road side units (RSUs); and a step for transmitting a second message to the one or more RSUs, wherein the first message includes location information about each of the one or more RSUs, the location information being acquired by recognizing unique information about each of the one or more RSUs, and the second message includes a location list obtained by collecting the location information about each of the one or more RSUs.
Abstract:
A method by which a first user terminal transmits a signal in a wireless communication system is disclosed. The method can comprise: monitoring a message related to the mobility of one or more user terminals; transmitting, to a second user terminal selected from among the one or more user terminals, a message for requesting to join a cluster to which the first user terminal belongs; receiving, from the second user terminal, a message for acknowledging joining of the cluster; and transmitting a message related to the mobility of the cluster. In addition, the second user terminal can be selected on the basis of comparison between the mobility of the cluster and the mobility of the second user terminal.
Abstract:
Disclosed is a method for a vehicle to communicate with a network in a wireless communication system. The method may comprise: receiving a message related to a parking lot from the network; transmitting, to the network, a message for requesting a reservation for a specific parking space from among at least one parking space in the parking lot; and receiving a message including the spatial coordinates of the specific parking space. In particular, the message for reservation includes type information of the vehicle, and the spatial coordinates of the specific parking space may be dynamically determined on the basis of the type information of the vehicle and type information of the at least one parking space.
