1. A wireless device, comprising:
at least one antenna; and
a processor;
wherein the wireless device is configured to:
determine whether simultaneous transmission of at least two sounding reference signals (SRSs) is allowed;
if it is determined that the simultaneous transmission of the at least two SRSs is allowed, transmit the at least two SRSs simultaneously; and
if it is determined that the simultaneous transmission of the at least two SRSs is not allowed:
transmit one SRS of the at least two SRSs, and drop the other SRS of the at least two SRSs; and
determine priority of each of the at least two SRSs,
wherein the one SRS of the at least two SRSs with higher priority is transmitted, and the other SRS of the at least two SRSs with lower priority is dropped,
wherein the priority is determined by usage of each of the at least two SRSs,
wherein the usage is selected from a group comprising at least codebook (CB), non-codebook (NCB), beam management (BM) and antenna switching (AS), and
wherein priority of a SRS for CB or NCB is higher than priority of a SRS for AS, and priority of a SRS for AS is higher that priority of a SRS for BM.
