Abstract

Methods, systems, and devices for designing and configuring reference signals in wireless communication systems are disclosed. An example method for wireless communication includes transmitting, by a wireless device to a network node, a sounding reference signal (SRS), where the SRS is determined by a first parameter and a cyclic shift parameter, and a value of the first parameter hops at a level of a first type of time unit and a value of the cyclic shift parameter hops at a level of a second type of time unit. Another example method for wireless communication includes receiving, by a wireless device from a network node, a configuration for an SRS resource, and transmitting an SRS in the SRS resource, where the configuration includes information associated with one or more time-domain orthogonal cover codes (TD-OCC) or a multiplexing type for multiple SRS ports in the SRS resource.
