Abstract

Disclosed is a method comprising obtaining one or more antenna-port-specific repetition patterns and/or one or more antenna-port-specific uplink power control target values for a plurality of antenna ports; and transmitting an uplink reference signal by applying antenna switching to at least a subset of the plurality of antenna ports based at least partly on the one or more antenna-port-specific repetition patterns and/or the one or more antenna-port-specific uplink power control target values.

Claims (7)

1 . An apparatus comprising:

at least one processor; and

at least one memory including instructions, which when executed by the at least one processor, cause the apparatus to:

obtain one or more antenna-port-specific repetition patterns and one or more antenna-port-specific uplink power control target values for a plurality of antenna ports;

transmit an uplink reference signal by applying antenna switching to at least a subset of the plurality of antenna ports based at least partly on the one or more antenna-port-specific repetition patterns and the one or more antenna-port-specific uplink power control target values, wherein the one or more antenna-port-specific repetition patterns cause the apparatus to repeat a transmission of resource elements associated with at least one antenna port of the plurality of antenna ports over consecutive and non-consecutive symbols, while transmitting the uplink reference signal;

determine one or more antenna-port-specific uplink power control values based at least partly on the one or more antenna-port-specific uplink power control target values and a downlink reference signal per reception antenna port associated with a corresponding antenna port of the plurality of antenna ports, wherein the determined one or more antenna-port-specific uplink power control values are applied to one or more antenna ports of the plurality of antenna ports, while transmitting the uplink reference signal; and

update the one or more antenna-port-specific repetition patterns and the one or more antenna-port-specific uplink power control target values before transmitting the uplink reference signal, wherein the uplink reference signal is transmitted based at least partly on the updated one or more antenna-port-specific repetition patterns and the updated one or more antenna-port-specific uplink power control target values.
