Abstract: Disclosed are techniques for wireless communication. In an aspect, a network entity, such as a location server or base station, may determine a positioning reference signal (PRS) frequency hopping configuration that specifies a plurality of PRS hops within a PRS resource set, each PRS hop occupying a specified set of one or more contiguous physical resource blocks, and further specifying a time gap between PRS hops to allow a sufficient retuning gap for a user equipment (UE) with reduced BW capability and/or relaxed processing time. The network entity may transmit the PRS frequency hopping configuration to at least one UE, e.g., via broadcast, multicast, groupcast, or unicast over Uu or PC5 links. The pre-configured time gap between PRS hops allows a reduced capacity UE to retune its RF circuit and thus allow PRS measurements over a larger bandwidth than what the UE can support without frequency hopping.

Abstract: Methods, systems, and devices for joint sensing and data communication. A first sensing signal and a second sensing signal are transmitted in sequence, from a transmitter and using the same carrier frequency, for combined processing by a receiver. In some implementations, the sensing signals are radar signals. Data communication during an intervening time period between the first sensing signal and the second sensing signal involves the transmitter sending a data communication signal to another device or vice versa. Phase continuity between the first sensing signal and the second sensing signal can be maintained through performing radio frequency (RF) tuning on the transmitter after the transmitter transmits the data communication signal. The RF tuning may involve storing and restoring an operating state of a power amplifier in the transmitter. Alternatively, phase continuity can be maintained through preventing the transmitter from transmitting over an entirety of the intervening time period.
