Method for channel assignments in wireless systems
A wireless transmit/receive unit includes a receiver and a processor. The receiver is configured to receive a plurality of high-speed shared control channels (HS-SCCHs), wherein the plurality of HS-SCCHs are received over a plurality of discrete time intervals. The processor is configured to instruct the receiver to receive all of the plurality of HS-SCCHs during one of the plurality of discrete time intervals.
1. A wireless transmit/receive unit (WTRU), comprising:
a baseband device configured to receive information from a wireless network indicating a first pattern of time intervals that the WTRU is to monitor a plurality of high-speed shared control channels (HS-SCCHs), wherein the baseband device is further configured to not monitor the HS-SCCHs in time intervals outside the first pattern of time intervals; and
wherein the baseband device is further configured to receive information from the wireless network indicating a second pattern of time intervals in which the WTRU transmits a dedicated channel and a control channel, and the WTRU does not transmit the dedicated channel outside of the second pattern of time intervals.
2. The WTRU of claim 1 , wherein the first pattern of time intervals coincides with a time interval in which the WTRU also receives a downlink dedicated channel.
3. The WTRU of claim 1 , wherein the first pattern of time intervals coincides with a time interval in which the WTRU also receives a primary common control physical channel.
4. The WTRU of claim 1 , further comprising:
a transmitter configured to transmit a high-speed shared information channel (HS-SICH) in a time interval during which the WTRU regularly transmits an uplink dedicated channel.
5. The WTRU of claim 4 , wherein the transmitter is further configured to transmit the HS-SICH in a frame that is later than a second frame during which the WTRU decodes data in a high-speed downlink shared channel.
6. A method for use by a wireless transmit/receive unit (WTRU), the WTRU including a baseband device, the method comprising:
receiving information by the baseband device from a wireless network, the information indicating a first pattern of time intervals that the WTRU is to monitor a plurality of high-speed shared control channels (HS-SCCHs), wherein the baseband device does not monitor the HS-SCCHs in time intervals outside the first pattern of time intervals;
receiving information from the wireless network indicating a second pattern of time intervals in which the WTRU transmits a dedicated channel and a control channel, and the WTRU does not transmit the dedicated channel outside of the second pattern of time intervals; and
turning off power to radio frequency components of the WTRU during time intervals not being monitored for HS-SCCHs or other communication channels.
7. The method of claim 6 , further comprising:
receiving a downlink dedicated channel (DL DCH) in the first pattern of time intervals; and
monitoring the first pattern of time intervals for the DL DCH.
8. The method of claim 6 , further comprising:
receiving a primary common control physical channel (P-CCPCH) in the first pattern of time intervals; and
monitoring the first pattern of time intervals for the P-CCPCH.
9. A wireless network device, comprising:
a high-speed downlink packet access allocation (HSDPA) controller configured to:
transmit information to a wireless transmit/receive unit (WTRU) indicating a first pattern of time intervals that the WTRU is to monitor a plurality of high-speed shared control channels (HS-SCCHs), wherein the WTRU does not monitor the HS-SCCHs in time intervals outside the first pattern of time intervals; and
transmit information to the WTRU indicating a second pattern of time intervals in which the WTRU transmits a dedicated channel and a control channel, wherein the WTRU does not transmit the dedicated channel outside of the second pattern of time intervals.
10. The wireless network device of claim 9 , wherein the first pattern of time intervals also contains a downlink dedicated channel.
11. The wireless network device of claim 9 , wherein the first pattern of time intervals also contains a primary common control physical channel.
12. The wireless network device of claim 9 , wherein the HSDPA controller is further configured to allocate a high-speed shared information channel (HS-SICH) to an uplink time interval which also contains an uplink dedicated channel, wherein the HS-SICH is allocated after a high-speed downlink shared channel is decoded.
13. A wireless network device, comprising:
a baseband device configured to transmit information to a wireless transmit/receive unit (WTRU) indicating a first pattern of time intervals that the WTRU is to monitor a plurality of high-speed shared control channels (HS-SCCHs), wherein the baseband device is further configured to only transmit the WTRU control information in the first pattern of time intervals; and
wherein the baseband device is further configured to transmit information to the WTRU indicating a second pattern of time intervals in which the WTRU transmits a dedicated channel and a control channel, and the WTRU does not transmit the dedicated channel outside of the second pattern of time intervals.
