摘要：
A wireless transmit/receive unit, WTRU, and a method for implementing data security and automatic repeat request, ARQ, are disclosed. A cipher entity is configured to assign a generic sequence number, SN, to a data block in a layer above a radio link control, RLC, layer, wherein the generic SN is assigned by a packet data convergence protocol, PDCP, entity. The cipher entity is further configured to cipher an uplink data block for transmission using the generic SN, a ciphering key, and a bearer identity, in the layer above the RLC layer, and an outer automatic repeat request, ARQ, entity configured to perform ARQ operation for transmission and retransmission using an ARQ SN of the ciphered uplink data block wherein the ARQ operation is performed with an ARQ function located at an evolved NodeB, eNB.
