Claim 0:
1. A method performed by a base station, the method comprising:
transmitting a radio resource control (RRC) message, wherein the RRC message indicates a set of resource blocks and includes information for a first wireless transmit/receive unit (WTRU) to determine at least one location within the set of resource blocks, the set of resource blocks including a plurality of locations indicating time-frequency orthogonal frequency division multiplex (OFDM) resource assignments for a plurality of WTRUs including the first WTRU, wherein different ones of the plurality of WTRUs search at different locations within the indicated set of resource blocks for one or more resource assignment messages;
transmitting one or more resource assignment messages to the first WTRU, wherein a first resource assignment message of the one or more resource assignment messages is associated with a persistent allocation of resources and indicates activation of a resource for the first WTRU;
receiving a plurality of uplink signals in a plurality of time intervals based on the indicated activation of the resource for the first WTRU;
transmitting, in a subsequent time interval than the set of resource blocks having the first resource assignment message, one or more resource assignment messages to the first WTRU including a second resource assignment message for the first WTRU, wherein the second resource assignment message indicates deactivation of the resource for the first WTRU, wherein the plurality of uplink signals are received until the resource is deactivated based on the indicated deactivation of the resource for the first WTRU; and
transmitting at least a third resource assignment message to the first WTRU, wherein the third resource assignment message changes the resource assignment associated with the persistent allocation of resources.
