Patent ID: 7376879

Claim:
A user equipment comprising: a hybrid automatic repeat request (H-ARQ) entity configured to generate a negative acknowledgement (NACK) after a first high speed medium access control (MAC-hs) data block including first information is transmitted to the user equipment over a wideband code division multiple access (WCDMA) high speed downlink shared channel (HSDSCH), the H-ARQ entity also being configured to receive and process a second MAC-hs data block instead of a third MAC-hs data block, the second MAC-hs data block including second information, the first information being retransmitted to the user equipment in the third MAC-hs data block after the second MAC-hs data block has been transmitted to the user equipment, the second and third MAC-hs data blocks having respective priority class identifiers indicating a higher transmission priority for the second MAC-hs data block than the third-MAC-hs data block; and at least one reordering entity configured to reorder a plurality of MAC-hs data blocks received by the HARQ entity, the plurality of MAC-hs data blocks including the second MAC-hs data block, said at least one reordering entity being configured to forward the plurality of MAC-hs data blocks for processing by protocol layers higher than a protocol layer associated with said at least one reordering entity, each of the plurality of MAC-hs data blocks having a corresponding one of a plurality of transmission sequence numbers (TSNs), the H-ARQ entity transmitting an acknowledgement (ACK) in response to each of the plurality of MAC-hs data blocks, the plurality of MAC-hs data blocks being transmitted to the user equipment on the WCDMA HS-DSCH.
