1. A method implemented in a wireless transmit/receive unit (WTRU), the method comprising:
receiving a first transmission indicating (i) a first plurality of uplink frequency resources allocated to the WTRU for a first slot and (ii) a plurality of transmit precoding matrix indices (TPMI) for a plurality of subbands of a first band of a bandwidth and for a second band of the bandwidth, wherein the first plurality of uplink frequency resources corresponds to a respective plurality of frequencies of the first band;
determining, based on the plurality of TPMI and one or more codebooks, a plurality of first precoders corresponding to the plurality of subbands of the first band and a second precoder corresponding to the second band;
performing precoding of first information using the plurality of first precoders;
transmitting the precoded first information during the first slot using the first plurality of uplink resources;
receiving a second transmission indicating a second plurality of uplink frequency resources allocated to the WTRU for a second slot, wherein the second plurality of uplink frequency resources corresponds to a respective plurality of frequencies including at least one frequency of the second band and zero or more frequencies of the plurality of subbands;
performing precoding of second information using the second precoder and zero or more of the plurality of first precoders in accordance with the second plurality of uplink frequency resources corresponding to the at least one frequency of the second band and zero or more frequencies of the plurality of subbands, respectively; and
transmitting the precoded second information on the second plurality of uplink frequency resources during the second slot.
