1. A wireless transmit/receive unit (WTRU) comprising: a processor configured to periodically send, via an uplink channel, channel quality indicators (CQIs);the processor further configured to decode a transmission on a downlink control channel, the transmission being associated with a radio network

1. A wireless transmit/receive unit (WTRU) comprising: a processor configured to periodically send, via an uplink channel, channel quality indicators (CQIs);the processor further configured to decode a transmission on a downlink control channel, the transmission being associated with a radio network temporary identifier (RNTI) of the WTRU;the processor further configured to determine that a wireless network is requesting the WTRU to send a CQI based on a triggering criteria associated with the transmission on the downlink control channel; andthe processor further configured to send the CQI to the wireless network. 2. The WTRU of claim 1, wherein the uplink channel is one of a shared channel, a common channel, or a random access channel (RACH). 3. The WTRU of claim 1, wherein the processor is further configured to send, to the wireless network, acknowledgements and negative acknowledgements via the uplink channel. 4. The WTRU of claim 1, wherein the WTRU is further configured to send the CQI via the uplink channel. 5. The WTRU of claim 1, wherein the downlink control channel is a shared channel. 6. The WTRU of claim 1, wherein the downlink control channel is a high speed shared control channel (HS-SCCH). 7. The WTRU of claim 1, wherein the triggering criteria is one of a trigger or a poll. 8. The WTRU of claim 1, wherein the processor is configured to detect or receive the RNTI on the downlink control channel. 9. A method performed by a wireless transmit/receive unit (WTRU), the method comprising: periodically sending, by the WTRU via an uplink channel, channel quality indicators (CQIs);decoding, by the WTRU, a transmission on a downlink control channel, the transmission being associated with a radio network temporary identifier (RNTI) of the WTRU;determining, by the WTRU, that a wireless network is requesting the WTRU to send a CQI based on a triggering criteria associated with the transmission on the downlink control channel; andsending, by the WTRU, the CQI to the wireless network. 10. The method of claim 9, wherein the uplink channel is one of a shared channel, a common channel, or a random access channel (RACH). 11. The method of claim 9, further comprising: sending, by the WTRU to the wireless network, acknowledgements and negative acknowledgements via the uplink channel. 12. The method of claim 9, wherein the CQI is sent to the wireless network via the uplink channel. 13. The method of claim 9, wherein the downlink control channel is a shared channel. 14. The method of claim 9, wherein the downlink control channel is a high speed shared control channel (HS-SCCH). 15. The method of claim 9, wherein the triggering criteria is one of a trigger or a poll. 16. The method of claim 9, wherein the RNTI is detected or received by the WTRU on the downlink control channel. 17. A wireless network device comprising: a processor configured to periodically receive, from a wireless transmit/receive unit (WTRU) via an uplink channel, channel quality indicators (CQIs);the processor further configured to send, via a downlink channel, a transmission associated with a radio network temporary identifier (RNTI) of the WTRU, wherein the transmission is associated with triggering criteria that indicates a request for the WTRU to send a CQI; andthe processor further configured to receive the CQI from the WTRU. 18. The wireless network device of claim 17, wherein the wireless network device is a Node B. 19. The wireless network device of claim 17, wherein the uplink channel is one of a shared channel, a common channel, or a random access channel (RACH). 20. The wireless network device of claim 17, wherein the processor is further configured to receive, from the WTRU, acknowledgements and negative acknowledgements via the uplink channel. 21. The wireless network device of claim 17, wherein the wireless network device is further configured to receive the CQI via the uplink channel. 22. The wireless network device of claim 17, wherein the downlink control channel is a shared channel. 23. The wireless network device of claim 17, wherein the downlink control channel is a high speed shared control channel (HS-SCCH). 24. The wireless network device of claim 17, wherein the triggering criteria is one of a trigger or a poll for the WTRU to send the CQI. 25. A method performed by a wireless network device, the method comprising: periodically receiving, by the wireless network device from a wireless transmit/receive unit (WTRU), channel quality indicators (CQIs) via an uplink channel;sending, by the wireless network device via a downlink control channel, a transmission associated with a radio network temporary identifier (RNTI) of the WTRU, wherein the transmission is associated with triggering criteria that indicates a request for the WTRU to send a CQI; andreceiving the CQI from the WTRU. 26. The method of claim 25, wherein the wireless network device is a Node B. 27. The method of claim 25, wherein the uplink channel is one of a shared channel, a common channel, or a random access channel (RACH). 28. The method of claim 25, further comprising: receiving, by the wireless network device from the WTRU, acknowledgements and negative acknowledgements via the uplink channel. 29. The method of claim 25, wherein the CQI is received via the uplink channel. 30. The method of claim 25, wherein the downlink control channel is a shared channel. 31. The method of claim 25, wherein the downlink control channel is a high speed shared control channel (HS-SCCH). 32. The method of claim 25, wherein the triggering criteria comprise one of a trigger or a poll for the WTRU to send the CQI.
