Use of uplink beam tracking results in reference symbol sessions

An apparatus for wireless communication by a user equipment (UE), comprising:

• a processor, memory coupled with the processor;
• and instructions stored in the memory and executable by the processor to cause the apparatus to:
• receive a request message from a base station, the request message comprising a request for the UE to transmit a set of sounding reference signals (SRSs);
• transmit, using at least two beamformed signals, the set of SRSs to the base station in accordance with the request message, the at least two beamformed signals being associated with a co-phasing parameter;
• receiving, from the base station based at least in part on the transmitted set of SRSs and the co-phasing parameter, an antenna port precoder configuration associated with the co-phasing parameter;
• and
• communicate with the base station using one or more beamformed signals configured according to the received antenna port precoder configuration.

An apparatus for wireless communication by a user equipment (UE), comprising:

• means for receiving a request message from a base station, the request message comprising a request for the UE to transmit a set of sounding reference signals (SRSs);
• means for transmitting, using at least two beamformed signals, the set of SRSs to the base station in accordance with the request message, the at least two beamformed signals being associated with a co-phasing parameter;
• means for receiving, from the base station based at least in part on the transmitted set of SRSs and the co-phasing parameter, an antenna port precoder configuration associated with the co-phasing parameter;
• and
• means for communicating with the base station using one or more beamformed signals configured according to the received antenna port precoder configuration.

A non-transitory computer-readable medium storing code for wireless communication by a user equipment (UE), the code comprising instructions executable by a processor to:

• receive a request message from a base station, the request message comprising a request for the UE to transmit a set of sounding reference signals (SRSs);
• transmit, using at least two beamformed signals, the set of SRSs to the base station in accordance with the request message, the at least two beamformed signals being associated with a co-phasing parameter;
• receive, from the base station based at least in part on the transmitted set of SRSs and the co-phasing parameter, an antenna port precoder configuration associated with the co-phasing parameter;
• and
• communicate with the base station using one or more beamformed signals configured according to the received antenna port precoder configuration.
