1. A method of wireless communication at a network device comprising:
receiving a first sounding reference signal (SRS) from a first user equipment (UE), the first SRS transmitted on first SRS resources, wherein the first SRS resources comprise one or more time resources and one or more frequency resources;
receiving a second SRS from a second different UE, the second SRS transmitted on second SRS resources, wherein the second SRS resources comprise one or more time resources and one or more frequency resources, wherein the second SRS is elongated such that the second SRS is received during an uplink period of a first subframe and during at least a portion of a second subframe that includes downlink resources, and wherein at least some of the first SRS resources overlap with the second SRS resources;
using the received first SRS to determine first beamforming parameters; and
using the received second SRS to determine second beamforming parameters.
