Abstract
Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a transmitter user equipment (UE) may detect an available bandwidth for transmission of a sidelink positioning reference signal. The transmitter UE may transmit the sidelink positioning reference signal in the available bandwidth, wherein a duration of the sidelink positioning reference signal is based at least in part on the available bandwidth. Numerous other aspects are described.
Claims30
A method of wireless communication performed by a transmitter user equipment (UE), comprising:
- performing a channel access procedure in a set of channels until the channel access procedure succeeds in a number of channels that satisfies a threshold;
- detecting an available bandwidth, based at least in part on the channel access procedure, for transmission of a sidelink positioning reference signal, wherein the available bandwidth is a bandwidth of the number of channels;
- and
- transmitting the sidelink positioning reference signal in the available bandwidth based at least in part on the bandwidth of the number of channels, wherein a duration of the sidelink positioning reference signal is based at least in part on the available bandwidth.
A method of wireless communication performed by a receiver user equipment (UE), comprising:
- determining a bandwidth used for a transmission of a sidelink positioning reference signal, wherein the bandwidth is based at least in part on a number of channels used for the transmission of the sidelink positioning reference signal;
- determining a duration of the sidelink positioning reference signal based at least in part on the bandwidth;
- and
- measuring the sidelink positioning reference signal based at least in part on the bandwidth and the duration.
A transmitter user equipment (UE) for wireless communication, comprising:
- a memory;
- and
- one or more processors, coupled to the memory, configured to:
- perform a channel access procedure in a set of channels until the channel access procedure succeeds in a number of channels that satisfies a threshold;
- detect an available bandwidth, based at least in part on the channel access procedure, for transmission of a sidelink positioning reference signal, wherein the available bandwidth is a bandwidth of the number of channels;
- and
- transmit the sidelink positioning reference signal in the available bandwidth based at least in part on the bandwidth of the number of channels, wherein a duration of the sidelink positioning reference signal is based at least in part on the available bandwidth.
