The described techniques provide for a base station transmitting to a user equipment (UE) a partial bandwidth configuration for uplink transmissions, where the partial bandwidth configuration may indicate a channel interlace and a portion of a channel bandwidth, for example, for autonomous uplink (AUL) transmissions. The base station may also transmit to the UE an AUL configuration including a group identifier. The UE may determine a starting offset with respect to an AUL subframe for a partial bandwidth transmission based on the group identifier. In some cases, different UEs may be grouped into groups of UEs allocated non-overlapping resources, and UEs allocated overlapping resources may have different starting offsets to begin transmitting. According to the determined starting offset, the UE may perform the partial bandwidth transmission over the channel interlace and the portion of the channel bandwidth.

  • Patent number: 11832222
    Abstract: 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.
