1. A method performed by a wireless transmit/receive unit (WTRU), the method comprising:
receiving a configuration comprising a plurality of sets of uplink transmission timing parameters, wherein each set of uplink transmission timing parameters comprises respective uplink transmission start position information and respective transmission length information, each set of uplink transmission timing parameters is associated with a respective index, the respective uplink transmission start position information indicates when the WTRU is to start a respective uplink shared channel transmission after receiving an uplink grant, and the respective transmission length information indicates a length of the respective uplink shared channel transmission;
receiving a first physical downlink control channel (PDCCH) transmission comprising a first uplink grant, wherein the first uplink grant comprises an index indicating which set of the plurality of sets of uplink transmission timing parameters is to be used for a first uplink shared channel transmission;
determining, based on the set of uplink transmission timing parameters indicated by the index comprised in the first uplink grant, a start time and a length of the first uplink shared channel transmission; and
sending the first uplink shared channel transmission in accordance with the determined start time and the determined length.
