Abstract
A wireless communication system having a Node B and a plurality of wireless transmit/receive units (WTRUs), includes a contention-based uplink (UL) channel and at least one downlink (DL) physical channel. The UL channel supports UL transmissions from the WTRUs to the Node B. The UL channel is randomly accessed by a WTRU when the WTRU is ready to transmit data. The DL physical channel supports DL transmissions from the Node B to the WTRUs. The DL transmissions include an acquisition indicator and information regarding said acquisition indicator. The acquisition indicator confirms whether the data transmitted over said UL channel was successfully received by the Node B.
Claims19
A method for acknowledgment of transmissions in wireless communications comprising:
- accessing an uplink (UL) channel, the UL channel including at least two codes for transmission;
- receiving an acquisition indicator transmitted on a downlink (DL) channel;
- and
- confirming, with said acquisition indicator, separately for each of said codes, whether the data transmitted over said UL channel was successfully received.
A wireless transmit/receive unit (WTRU) comprising:
- a transmitter configured to transmit uplink (UL) transmissions on an UL channel, the uplink channel comprising at least two codes for transmission;
- a receiver configured to receive downlink (DL) transmissions in at least one DL physical channel, the downlink transmissions including an acquisition indicator configured for separately confirming for each code whether data transmitted over the UL channel was successfully received.
