Abstract
A method and a wireless transmit/receive unit (WTRU) are disclosed. The WTRU comprises a transceiver and a processor. The WTRU receives a system information block (SIB) from a base station, wherein the SIB indicates random access transmission uplink resources. After receiving the SIB, the WTRU transmits a random access preamble to the base station. After transmitting the random access preamble, the WTRU transmits, using one or more of the uplink resources indicated by the SIB, a first message to the base station, wherein the first message includes a first radio network temporary identifier (RNTI) of the WTRU. After transmitting the first message, the WTRU receives a second message from the base station, wherein the second message is derived from a second RNTI, the second RNTI being different than the first RNTI. After receiving the second message, the WTRU transmits to the base station.

12. The method of claim 11, wherein the first message is transmitted using a HARQ process.
13. The method of claim 11, further comprising calculating a third RNTI for random access transmissions with the second cell.
14. The method of claim 11, wherein the third RNTI is the same as the first RNTI or the second RNTI.
15. The method of claim 11, wherein the second message is derived from the first RNTI and the second RNTI.
16. A wireless transmit/receive unit (WTRU) comprising:
a transceiver; and a processor, wherein the transceiver and the processor are configured to cause the WTRU to: receive control information from a first cell, wherein the control information indicates uplink resources for use with random access transmission; after receiving the control information, transmit a random access preamble to a second cell; after transmitting the random access preamble, transmit, using one or more of the uplink resources indicated by the control information, a first message to the second cell, wherein the first message includes a first radio network temporary identifier (RNTI) of the WTRU; after transmitting the first message, receive a second message from the second cell, wherein the second message is derived from a second RNTI, the second RNTI being different than the first RNTI; and after receiving the second message, transmit to the second cell.
17. The WTRU of claim 16, wherein the first message is transmitted using a HARQ process.
18. The WTRU of claim 16, further comprising calculating a third RNTI for random access transmissions with the second cell.
19. The WTRU of claim 16, wherein the third RNTI is the same as the first RNTI or the second RNTI.
20. The WTRU of claim 16, wherein the second message is derived from the first RNTI and the second RNTI.
