WIRELESS COMMUNICATION METHOD AND APPARATUS COORDINATING NODE-B AND SUPPORTING ENHANCED UPLINK TRANSMISSIONS DURING HANDOVER
摘要
A method for enhanced uplink (EU) communication during soft handover implemented in a Node-B operating as a primary Node-B. The Node-B receives information from a radio network controller (RNC) and uses the information to determine uplink scheduling information including the maximum transmission power of a wireless transmit/receive unit (WTRU). The Node-B transmits to the WTRU the uplink scheduling information, wherein the uplink scheduling information is not transmitted to the WTRU by any non-primary Node-B. The Node-B receives an EU data packet from the WTRU and performs a cyclic redundancy check (CRC) on the EU data packet. The Node-B transmits an acknowledgment (ACK) or a negative acknowledgment (NACK) to the WTRU in response to the received EU data packet. Further, the Node-B transmits a successfully received EU data packet to the RNC.
