20 Claims

1. A baseband processor comprising one or more processors configured to perform operations comprising:

causing transmission of a capability message to a base station (BS), the capability message indicating a full power uplink transmission capability for a user equipment (UE), wherein the UE comprises a first number of ports, and wherein the full power uplink transmission capability indicates support for full power uplink transmission using both the first number of ports and fewer than the first number of ports without explicit additional signaling of a full power capability for fewer than the first number of ports;

receiving, from the BS, an indication of a sounding reference signal (SRS) resource associated with a second number of ports that is less than the first number of ports; and

causing transmission of at least one SRS to the BS over the SRS resource using the second number of ports.
