Question: In HSDPA transmissions using HS-DSCH, if a User Equipment (UE) receives an inconsistent MAC-hs header with a SID field value of '111', how should it handle the associated PDU's?
Option 1: The UE shall process the PDU's normally, ignoring the inconsistency in the SID field.
Option 2: The UE shall discard the PDU's according to the specifications outlined for handling inconsistent MAC-hs headers.
Option 3: The UE shall request retransmission of the PDU's due to the detected inconsistency.
Option 4: The UE shall suspend HSDPA transmission until a consistent MAC-hs header is received.
Explanation: When a UE receives an inconsistent MAC-hs header with a SID field value of '111' in HSDPA transmissions over HS-DSCH, it is mandated to discard the associated PDU's. This behavior prevents unspecified or erratic UE behavior when encountering such inconsistencies, ensuring predictable operation within the network.
