Display device

A base station transmits a random access response in response to a random access request (random access preamble) of a user equipment. The random access response includes information about a time when the random access request is transmitted and sequence number information of the random access request (random access preamble). The user equipment checks whether the received random access response is the response of the random access request transmitted by the user equipment, using the information about the time when the random access request is transmitted and the sequence number information included in the received random access response.

Method for transmitting and receiving random access request and transmitting and receiving random access response

A display device including a display panel has a folding portion, a metal layer disposed on one surface of the display panel, and including a first metal layer and a second metal layer spaced apart from each other in the folding portion, a first adhesive layer disposed at edges of the first metal layer and the second metal layer, and a first compressible member disposed on the first metal layer and a second compressible member disposed on the second metal layer, the first and second compressible members being disposed closer to the folding portion than the first adhesive layer, in which the first and second compressible members each have a thickness greater than a thickness of the first adhesive layer.

A method and apparatus for requesting uplink resources in a wireless communication system is provided. A user equipment determines whether a scheduling request for requesting uplink resources is triggered. If the scheduling request is triggered, the user equipment transmits a first set of frequency domain sequences and a second set of frequency domain sequences in a subframe.

Method of transmitting scheduling request in a wireless communication system

A symbol mapping method for repetition coding is disclosed. The symbol mapping method comprises performing repetition coding on codeword to output repeated codeword symbols, and mapping the repeated codeword symbols with subcarriers located in different localized resource blocks. According to the embodiments of the present invention, it is possible to obtain maximum reliability in a receiving side by mapping codeword bits with subcarriers to reduce the number of bits having low reliability when a transmitting side uses repetition coding. Also, it is possible to improve decoding throughput and obtain channel diversity.

Symbol mapping method for repetition channel coding

Disclosed is a data transmission method in a mobile communication system. The data transmission method through a code sequence in a mobile communication system includes grouping input data streams into a plurality of blocks consisting of at least one bit so as to map each block to a corresponding signature sequence, multiplying a signature sequence stream, to which the plurality of blocks are mapped, by a specific code sequence, and transmitting the signature sequence stream multiplied by the specific code sequence to a receiver.

Preamble sequence for a random access channel

A flexible display device includes a display panel configured to display an image, and a first electrical actuation part disposed at a first side of the display panel. The first electrical actuation part includes a first electro-active polymer and a first pair of electrodes. A first unit structure including the first electro-active polymer and the first pair of electrodes is repeatedly formed in the first electrical actuation part.

Flexible display device

A method and apparatus for transmitting or detecting primary synchronization signal. The receiver receives primary synchronization signal from a transmitter, and detects the sequence used in the received primary synchronization signal by using three root indexes. Here, the primary synchronization signal is generated by using a Zadoff-Chu sequence having one of the three root indexes. The three root indexes comprise a first index and a second index, and a sum of the first index and the second index corresponds to the length of the Zadoff-Chu sequence.

Method and apparatus for transmitting or detecting a primary synchronization signal

A method for transmitting a random access preamble to a base station includes generating the random access preamble from a Zadoff-Chu (ZC) sequence, wherein the random access preamble is defined by cyclic shift (C) of the ZC sequence; and transmitting the random access preamble to the base station.

Method for setting cyclic shift considering frequency offset

A method and a user equipment for transmitting control information in a communication system are discussed. The method according to an embodiment includes multiplying a transmission information symbol s for the control information by a frequency direction sequence c(k) to generate a first output sequence s(k), where s(k)=s*c(k), k=0, . . . , N&#x2212;1, and Ncorresponds to a number of subcarriers included in a resource block allocated for an uplink control channel; multiplying the first output sequence s(k) by a time direction sequence x(n) to generate a second output sequence s(k, n), where s(k, n)=s(k)*x(n), n=0, . . . , N&#x2212;1, and Ncorresponds to a number of symbols used for transmission of the control information in a transmission time interval; and transmitting the second output sequence s(k, n) through the uplink control channel in the transmission time interval.
