Patent ID: 8051354

Claim:
A method for realizing Hybrid Automatic Retransmission Request (HARQ) in a multi-carrier cell, comprising the following steps of: (a) Node B distributing high-speed downlink packet service to N frequencies when distributing high-speed shared resources for a user equipment (UE), N being a positive integer, and reporting information of established physical channel, including frequency information, to a Radio Network Controller (RNC) and said user equipment; (b) the Node B establishing a Hybrid Automatic Retransmission Request entity for said user equipment after establishing the high-speed shared resources at N frequencies for said user equipment, and establishing N Hybrid Automatic Retransmission Request sub-entities based on the entity, each sub-entity independently processing high-speed downlink packet service at one frequency; correspondingly, said user equipment also establishing N Hybrid Automatic Retransmission Request sub-entities on the Hybrid Automatic Retransmission Request entity; and (c) the Node B configuring parameters for each Hybrid Automatic Retransmission Request sub-entity and notifying the configuration information to the Radio Network Controller and said user equipment through upper-layer signalling, the Node B and the user equipment completing configuration for each sub-entity of their respective Hybrid Automatic Retransmission Request entity based on said configuration information and realizing the Hybrid Automatic Retransmission Request function in the service.
