A method of operation of a wireless communication device for transmitting a physical uplink channel in a wireless communication system , comprising: • transmitting a sounding reference signal on a first set of frequency-domain resources; • receiving an uplink scheduling assignment for an uplink physical channel, the uplink scheduling assignment comprising a resource allocation of a second set of frequency-domain resources, wherein the second set of frequency-domain resources comprises: (a) one or more frequency-domain resources that are also included in the first set of frequency-domain resources and (b) one or more frequency-domain resources that are not included in the first set of frequency-domain resources; • in order to form a precoded uplink channel: o for each frequency-domain resource of one or more frequency-domain resources comprised in both the first set of frequency-domain resources and the second set of frequency-domain resources, applying a same precoding to the uplink physical channel on the frequency-domain resource as applied to the sounding reference signal on the frequency-domain resource; and o for each frequency-domain resource of the one or more frequency-domain resources comprised in the second set of frequency-domain resources but not included in the first set of frequency-domain resources, applying a same precoding to the uplink physical channel on the frequency-domain resource as applied to the sounding reference signal on a different frequency-domain resource; and • transmitting the precoded uplink channel. • transmitting a sounding reference signal on a first set of frequency-domain resources; • receiving an uplink scheduling assignment for an uplink physical channel, the uplink scheduling assignment comprising a resource allocation of a second set of frequency-domain resources, wherein the second set of frequency-domain resources comprises: (a) one or more frequency-domain resources that are also included in the first set of frequency-domain resources and (b) one or more frequency-domain resources that are not included in the first set of frequency-domain resources; • in order to form a precoded uplink channel: o for each frequency-domain resource of one or more frequency-domain resources comprised in both the first set of frequency-domain resources and the second set of frequency-domain resources, applying a same precoding to the uplink physical channel on the frequency-domain resource as applied to the sounding reference signal on the frequency-domain resource; and o for each frequency-domain resource of the one or more frequency-domain resources comprised in the second set of frequency-domain resources but not included in the first set of frequency-domain resources, applying a same precoding to the uplink physical channel on the frequency-domain resource as applied to the sounding reference signal on a different frequency-domain resource; and o for each frequency-domain resource of one or more frequency-domain resources comprised in both the first set of frequency-domain resources and the second set of frequency-domain resources, applying a same precoding to the uplink physical channel on the frequency-domain resource as applied to the sounding reference signal on the frequency-domain resource; and o for each frequency-domain resource of the one or more frequency-domain resources comprised in the second set of frequency-domain resources but not included in the first set of frequency-domain resources, applying a same precoding to the uplink physical channel on the frequency-domain resource as applied to the sounding reference signal on a different frequency-domain resource; and • transmitting the precoded uplink channel. <EOS>
