Abstract:
Provided is a technology related to a sensor network, machine to machine (M2M), machine type communication (MTC), and the Internet of things (IoT). Transmitting data between transceivers including transmitting data segments of source data and parity data segments including restoration information for a transceiver to restore the source data. The method is applicable to intelligent services based on the technology (e.g., smart home services, smart building services, smart city services, smart or connected car services, health care services, digital education services, retail business services, security and safety-related services, etc.).
Abstract:
Provided is a method of transmitting and receiving data by a user equipment (UE), the method including receiving, by the UE, a first data stream including at least one of transmission data and a first error correction code regarding the transmission data, obtaining a second error correction code based on the transmission data obtained from the received first data stream, and transmitting a second data stream including at least one of recovered transmission data and the obtained second error correction code.
Abstract:
A method of and an apparatus for transmitting first data to a plurality of receiver terminals connected to a transmitter terminal through the transmitter terminal and transmitting second data to the plurality of receiver terminals through the transmitter terminal is performed according to a transmission speed determined based on at least one selected from feedback information of a receiver terminal selected based on a data loss rate of the first data and variation information of data stored in a buffer of the transmitter terminal.
Abstract:
The present disclosure is related to technology for a sensor network, machine to machine (M2M) communication, machine type communication (MTC), and Internet of Things (IoT). Provided is a method, performed by a server, of transmitting and receiving data, in which, as a transmission authority request is received from at least one terminal from among a plurality of terminals connected to the server, a number of transmitting terminals previously determined by the server is compared with a maximum number of transmitting terminals allowable by the server, in response to the transmission authority request, and a transmission authority of the at least one terminal is determined based on a result of the comparing. The present disclosure are applicable to intelligent services based on the technology (e.g., smart home, smart building, smart city, smart car or connected car, health care, digital education, retail business, security, and safety-related service).
Abstract:
A method for transmitting and receiving data, which is performed by a terminal, includes: transmitting first data to each of a plurality of reception terminals connected to the terminal, the first data including a source data segment and a parity data segment; determining second data to be transmitted after the first data, based on feedback information that relates to the first data and is received from each of the plurality of reception terminals; and transmitting the determined second data to each of the plurality of reception terminals.
