Abstract: Disclosed are techniques for positioning. A receiver measures a time of arrival (ToA) of a positioning reference signal (PRS) transmission of a first PRS sequence transmitted by a first transmitter, measures a ToA of a PRS transmission of a second PRS sequence transmitted by a second transmitter, and determines an observed time difference of arrival (OTDOA) as a difference between the ToA of the PRS transmission of the first PRS sequence and the ToA of the PRS transmission of the second PRS sequence, wherein the OTDOA is less than half a maximum differential delay expected between the PRS transmission of the first PRS sequence and the PRS transmission of the second PRS sequence, and wherein a repetition duration of the first PRS sequence and the second PRS sequence is greater than 10 milliseconds (ms) and at least twice the maximum differential delay.

Abstract: Aspects of the present disclosure provide systems and methods for informing a user equipment (UE) that which beam the UE is being served, for example, such as in relation to bandwidth part (BWP) switching in a non-terrestrial network (NTN). According to certain aspects, a network entity may transmit to a user equipment (UE) signaling indicating at least one BWP switch. The network entity provides, to the UE, an indication of a serving synchronization signal block (SSB) for the UE to use after the BWP switch.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a non-terrestrial network (NTN) entity, a message that is associated with an uplink grant. The UE may select, based at least in part on the message, either a cell-specific offset or an updated offset that is indicated after initial access, as a timing offset that accounts for a propagation delay between a base station of the NTN and the UE. The UE may transmit, to the NTN entity, an uplink communication using the timing offset. Numerous other aspects are described.

Abstract: The apparatus is configured to transmit and/or receive GDMRS that may be scrambled based on a same scrambling identifier (ID) and shared for a plurality of UEs or channels. The apparatus, in some configurations, is further configured to multiplex, in time, data for the plurality of UEs or channels into different segments within each symbol in a set of symbols. The apparatus is further configured to transmit and/or receive the multiplexed data for the plurality of UEs or channels. In some configurations, the apparatus is further configured to demodulate the received data based on the GDMRS, and extract at least one segment for a UE or a plurality of channels associated with the apparatus within the demodulated data for subsequent decoding at the apparatus. In some configurations the extraction is based on a SLIV transmitted and/or received by the apparatus.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a base station, a random access channel configuration that indicates one or more physical random access channel (PRACH) formats associated with antenna switching. The UE may transmit, to the base station, a PRACH sequence using a PRACH format associated with antenna switching from the one or more PRACH formats associated with antenna switching. Numerous other aspects are described.
