Patent ID: 8743794

Claim:
A method of a radio network controller transmitting data according to an allocated data capacity, comprising: the radio network controller receiving a capacity allocation frame regarding a user equipment using the High Speed Shared Packet Access (HSDPA) technology in the state of CELL_FACH and/or CELL_PCH/URA_PCH from a base station; and the radio network controller transmitting data to the base station, wherein the amount of data transmitted during one High Speed Downlink Shared Channel Interval is less than or equal to a product of Maximum Protocol Data Unit Length carried in said capacity allocation frame and maximum number of Protocol Data Units can be transmitted during one High Speed Downlink Shared Channel Interval; wherein the radio network controller transmits data to the base station according to information of capacity allocation carried in said capacity allocation frame; said information of capacity allocation comprises number of time intervals that a cache size of High Speed Downlink Shared Channel can be transmitted continuously, the Maximum Protocol Data Unit Length can be transmitted during one High Speed Downlink Shared Channel Interval, maximum number of Protocol Data Units can be transmitted during one High Speed Downlink Shared Channel Interval, and time interval that the cache size of High Speed Downlink Shared Channel can be transmitted.
