Sounding reference signal (SRS) configurations for one or more frequency hops

Abstract:

In an aspect, a UE receives an SRS configuration that indicates, for at least one frequency hop, an allocation of less than all subcarriers of a sounding bandwidth to SRS per OFDM symbol in a respective frequency hop. The UE transmits, to a BS in a first frequency hop, OFDM symbols with SRS across all subcarriers of a first sounding bandwidth associated with the first frequency hop. In another aspect, the UE receives an SRS configuration that indicates, for frequency hops associated with the same comb-type, a sequence of resource element offsets that is based on a number of OFDM symbols used in the respective frequency hop. The UE transmits OFDM symbols with SRS in accordance with the sequence of resource element offsets indicated by the SRS configuration for the respective frequency hop.
