Methods and WTRU for positioning with reduced latency in wireless communication systems

Abstract

The disclosure pertains to methods and apparatus for performing positioning of wireless transmit and/or receive units (WTRUs) in wireless communication systems. A WTRU may receive configuration information indicating a time window associated with positioning. The configuration information may indicate any of a duration and a periodicity of the time window. The WTRU may receive (1) first scheduling information indicating to transmit a first uplink transmission including a sounding reference signal (SRS) and (2) second scheduling information indicating to transmit a second uplink transmission including a positioning SRS (SRSp). The first uplink transmission may not include any SRSp. On condition that the second uplink transmission is scheduled for transmission during the time window, the WTRU may transmit the second uplink transmission during the time window and may transmit the first uplink transmission only when the first uplink transmission is scheduled for transmission outside of the time window.
