Abstract

Claims (27)

1 . An apparatus comprising:

at least one processor; and

at least one memory comprising computer program code,

the at least one memory and computer program code are configured, with the at least one processor, to cause the apparatus at least to:

wherein the apparatus is configured to transmit precoded signals using receive beamformers as transmit precoders over at least one of a plurality of transmission occasions and multiple antenna subsets;

receive configuration parameters, from a network node, for at least one of the precoded signals and the transmit precoders;

determine power scaling values based on the configuration parameters;

perform power scaling of the transmit precoders using the determined power scaling values;

provide an indication to the network node of the determined power scaling values; and

perform transmission of precoded signals using the transmit precoders scaled by the determined power scaling values.

2 . The apparatus according to claim 1 , wherein the configuration parameters comprise an indication of whether to use power scaling for the plurality of transmission occasions.

3 . The apparatus according to claim 1 , wherein the configuration parameters comprise an indication of a scaling method.

4 . The apparatus according to claim 1 , wherein the configuration parameters comprise reporting parameters.

5 . The apparatus according to claim 4 , wherein the at least one memory and computer program code are configured, with the at least one processor, to cause the apparatus at least to:

report, based on the reporting parameters, absolute power scaling values or power scaling values relative to a maximum power scaling value.

6 . The apparatus according to claim 1 , wherein the at least one memory and computer program code are configured, with the at least one processor, to cause the apparatus at least to:

provide a further indication from the apparatus to the network node that the apparatus is capable of using receive beamformers as transmit precoders for transmitting the precoded signals.

7 . The apparatus according to claim 6 , wherein the further indication comprises an indication that the user apparatus is capable of applying the receive beamformers over at least one of multiple transmission occasions and antenna subsets.

8 . The apparatus according to claim 1 wherein the precoded signals are data signals or reference signals.

9 . The apparatus according to claim 8 , wherein the reference signals comprise at least one of sounding reference signals, demodulation reference signals and non-zero power channel state information reference signals.

10 . A method, for a user equipment configured to transmit precoded signals using receive beamformers as transmit precoders over at least one of a plurality of transmission occasions and multiple antenna subsets, comprising:

receiving configuration parameters, from a network node, for at least one of the precoded signals and the transmit precoders;

determining power scaling values based on the configuration parameters;

performing power scaling of the transmit precoders using the determined power scaling values;

providing an indication to the network node of the determined power scaling values; and

performing transmission of precoded signals using the transmit precoders scaled by the determined power scaling values.

11 . The method according to claim 10 , wherein the configuration parameters comprise an indication of whether to use power scaling for the plurality of transmission occasions.
