Channel reciprocity for a multi-panel base station

A method of wireless communication by a base station, comprising:

• transmitting a plurality of indicators identifying a plurality of antenna panels on the base station to a user equipment (UE), wherein each indicator of the plurality of indicators identifies a respective panel of the plurality of antenna panels of the base station;
• communicating with the UE based on the plurality of indicators of the plurality of antenna panels,
• identifying one or more sounding reference signal (SRS) resources, wherein transmitting the plurality of indicators comprises transmitting resource information indicating the one or more SRS resources, each SRS resource of the one or more SRS resources being associated with at least one indicator of the plurality of indicators identifying at least one respective antenna panel of the plurality of antenna panels;
• and
• receiving a plurality of sounding reference signals (SRSs) from the UE via the plurality of antenna panels on the one or more SRS resources.

A user equipment (UE) for wireless communication, comprising:

• at least one processor;
• a transceiver communicatively coupled to the at least one processor;
• and
• a memory communicatively coupled to the at least one processor,
• wherein the at least one processor is configured to:
• receive, from a base station configured to communicate via a plurality of antenna panels, a plurality of indicators to respectively identify the plurality of antenna panels of the base station;
• and
• transmit a plurality of sounding reference signals (SRSs) respectively to the plurality of antenna panels of the base station based on the plurality of indicators,
• wherein the at least one processor configured to receive the plurality of indicators is configured to receive resource information indicating one or more sounding reference signal (SRS) resources from the base station, wherein each SRS resource of the one or more SRS resources is associated with at least one indicator of the plurality of indicators identifying at least one respective antenna panel of the plurality of antenna panels, and
• wherein the at least one processor configured to transmit the plurality of SRSs is configured to transmit the plurality of SRSs to the base station on the one or more SRS resources.

A method of wireless communication by a user equipment (UE), comprising:

• receiving, from a base station configured to communicate via a plurality of antenna panels, a plurality of indicators to respectively identify the plurality of antenna panels of the base station;
• transmitting a plurality of sounding reference signals (SRSs) respectively to the plurality of antenna panels of the base station based on the plurality of indicators,
• wherein said receiving the plurality of indicators includes receiving resource information indicating one or more sounding reference signal (SRS) resources from the base station, wherein each SRS resource of the one or more SRS resources is associated with at least one indicator of the plurality of indicators identifying at least one respective antenna panel of the plurality of antenna panels, and
• wherein said transmitting the plurality of SRSs includes transmitting the plurality of SRSs to the base station on the one or more SRS resources.
