    摘要： Disclosed are methods, apparatuses, systems, and computer readable media. In one aspect, a wireless communication method is disclosed. The method includes generating, at a first radio terminal, a signal comprising a pilot signal, wherein the pilot signal includes W pilot sequences, wherein W is an integer, and wherein the W pilot sequences are uncorrelated; and transmitting, from the first radio terminal to a second radio terminal, the signal.

    摘要： A wireless communication device and a communication method for header repetition are described. The device and method receive and decode a wireless packet through a communication channel. Formats of the wireless packet includes a first packet format and a second packet format. In this regard, the first packet format comprises a first header field carried by a first orthogonal frequency division multiplexing (OFDM) symbol while the second packet format comprises both the first header field carried by the first OFDM symbol and a second header field carried by a second OFDM symbol which follows the first OFDM symbol. The second header field is a repetition of the first header field. According to an exemplary embodiment, the second packet format is distinguished from the first packet format by detecting, from the received wireless packet, the second header field which repeats the first header field.

    摘要： This disclosure provides systems, methods and apparatus, including computer storage media, for sidelink communications using partial symbols to reduce overhead of automatic gain control (AGC) and gaps. A transmitting user equipment (UE) maps a sidelink signal to a subset of resource elements in a frequency domain allocation defined via a comb for a first orthogonal frequency division multiplexing (OFDM) symbol. The transmitting UE performs an inverse discrete Fourier transform (IDFT) on the resource elements to generate a first time domain signal that includes a number of repetitions of a first waveform based on a structure of the comb. The transmitting UE transmits at least one repetition of the first waveform of the first time domain signal during at least a portion of the first OFDM symbol. A receiving UE performs AGC and a discrete Fourier transform on portions of the time domain signal.
