Abstract:
A shape compliant gripper with which an atypical object having various shapes, sizes and materials can be picked. The shape compliant gripper comprises a body and a shape compliant module disposed on the body and having rigidity capable of being variably controlled. Further, the shape compliant module comprises a magnetorheological elastomer, a magnet part, and a control part for controlling a position of the magnet part with respect to the magnetorheological elastomer.
Abstract:
The present invention proposes an apparatus and a method capable of forming M*N number of beams by a base station, which supports signal transmission/reception of the macro service area in heterogeneous networks in which a macro service area is formed with the M*N number of beams through a two-dimensional arrangement simultaneously considering the horizontal dimension and the vertical dimension and at least one small service is formed in the macro service area. To this end, at least one interference prediction beam formed to transmit signals interfering in transmission signals in at least one small service area from among the signals to be transmitted by the M*N number of beams is selected, and each of the M*N number of beams is formed in consideration of the inter-cell interference in at least one small service area due to the signals to be transmitted by at least one selected interference prediction beam.

Abstract:
A channel access method for rapid transmission of data in a communication system includes the steps of: performing, for transmission to a first STA, backoff procedures for all ACs; if, from among the backoff procedures, a first backoff procedure has been successful, transmitting, to the first STA, a first data frame associated with the first backoff procedure; and receiving, from the first STA, a reception response frame to the first data frame.
Abstract:
A method and a device are disclosed for a non-simultaneous transmit and receive (NSTR) operation in a communication system supporting multiple links. An operating method of a device comprises the steps of: receiving, from an AP, a first frame including configuration information about a TWT SP in a first link from among multiple links; transmitting, to an STA, a second frame including configuration information about a QTP overlapping with the TWT SP in a second link from among the multiple links; and communicating with the AP within the TWT SP configured in the first link.
Abstract:
In a method and device for transmitting and receiving rapid data in a communication system, an AP method includes the steps of: setting a first TS for a first STA; setting a second TS for a second STA; transmitting a first data frame of the first STA in the first TS; and transmitting a second data frame of the second STA in a transmission interval including the second TS, wherein the first TS and the second TS are sequentially set in an rTWT SP.
Abstract:
A method and device for transmitting and receiving data in a communication system supporting multiple links include the steps of performing a first backoff operation for a first frame to be transmitted to first STA MLD in a first link from among multiple links; performing a second backoff operation for a second frame to be transmitted to second STA MLD in the first link; deferring transmission to the first frame if the first backoff operation is complete and communication between the AP MLD and the first STA MLD is established in a second link from among the multiple links; and transmitting the second frame to the second STA MLD in the first link if the second backoff operation is complete.
Abstract:
A method and a device are disclosed for address resolution protocol (ARP) operation in a communication system supporting multiple links. An operation method of a first device comprises the steps of: receiving, from a communication node, an ARP request packet requesting the transmission of a MAC address of a second device connected to the first device; finding, in an ARP table stored in the first device, a representative MAC address of the second device requested by the ARP request packet; and transmitting an ARP response packet including the representative MAC address to the communication node.
