Abstract: Techniques are described herein to secure a packet data convergence protocol (PDCP) control protocol data unit (PDU). A base station may determine a security configuration for a PDCP control PDU based on various factors including the content of the PDCP control PDU. For example, the security configuration of the PDCP control PDU may be applied because the PDCP control PDU includes a retransmission request. A counter dedicated to PDCP control PDUs may be initialized. The security protocols may be based on the dedicated counter. Some types of security parameters may be shared in some contexts such as in handover procedures or dual connectivity procedures. For example, security configurations associated with a second communication link may be based on security configurations associated with a first communication link. PDCP control PDUs may be secured based on the security configurations, the security parameters, protection keys, or combinations thereof.
