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

Claim
1. A method performed by a base station, the method comprising:
transmitting a system information block (SIB) to a wireless transmit/receive unit (WTRU), wherein the SIB indicates random access transmission uplink resources; after transmitting the SIB, receiving a random access preamble from the WTRU; after receiving the random access preamble, receiving, using one or more of the uplink resources indicated by the SIB, a first message from the WTRU, wherein the first message includes a first radio network temporary identifier (RNTI) of the WTRU; and after receiving the first message, transmitting a second message to the WTRU, wherein the second message is derived from a second RNTI, the second RNTI being different than the first RNTI.
2. The method of claim 1, wherein the first message is received using a HARQ process.
3. A base station comprising:
a transceiver; and a processor, wherein the transceiver and the processor are configured to cause the base station to: transmit a system information block (SIB) to a wireless transmit/receive unit (WTRU), wherein the SIB indicates random access transmission uplink resources; after transmitting the SIB, receive a random access preamble from the WTRU; after receiving the random access preamble, receive, using one or more of the uplink resources indicated by the SIB, a first message from the WTRU, wherein the first message includes a first radio network temporary identifier (RNTI) of the WTRU; and after receiving the first message, transmitting a second message to the WTRU, wherein the second message is derived from a second RNTI, the second RNTI being different than the first RNTI.

6. The method of claim 5, wherein the first message is received using a HARQ process.
7. A base station comprising:
a transceiver; and a processor, wherein the transceiver and the processor are configured to cause the base station to: transmit control information on a first cell to a wireless transmit/receive unit (WTRU), wherein the control information indicates random access transmission uplink resources; after transmitting the control information, receive a random access preamble from the WTRU on a second cell; after receiving the random access preamble, receive, using one or more of the uplink resources indicated by the control information, a first message from the WTRU on the second cell, wherein the first message includes a first radio network temporary identifier (RNTI) of the WTRU; after receiving the first message, transmit a second message to the WTRU, 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 WTRU on the second cell.
8. The base station of claim 7, wherein the message is received using a HARQ process.
