1. A method implemented in a wireless transmit receive unit (WTRU), the method comprising:
receiving configuration information associated with a serving cell, wherein the configuration information indicates at least a first subset of contiguously indexed resource blocks (RBs) of a carrier and a second subset of contiguously indexed RBs of the carrier;
transmitting or receiving information in the serving cell using the first subset of contiguously indexed RBs of the carrier;
receiving a physical downlink control channel (PDCCH) transmission comprising downlink control information (DCI) associated with a radio network temporary identifier (RNTI), wherein the DCI indicates that the WTRU is to activate the second subset of contiguously indexed RBs of the carrier for communicating information in the serving cell;
activating the second subset of contiguously indexed RBs of the carrier for communicating information in the serving cell based on receiving the PDCCH transmission; and
deactivating the first subset of contiguously indexed RBs of the carrier for communicating information in the serving cell based on receiving the PDCCH transmission.
