摘要： Aspects of the present disclosure provide various apparatuses and methods for formatting and decoding a protocol data unit (PDU) or data packet such that header size and packet processing time at the transmitter and/or receiver can be reduced. The proposed PDU formats may facilitate more efficient packet processing at a medium access control (MAC) layer, a radio link control (RLC) layer, and/or a packet data convergence protocol (PDCP) layer, and less dependent on the number of service data units (SDUs) included in a PDU.

摘要： 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.

摘要： A first method includes transmitting, to a network, an indication of a capability to operate in an uplink aggregation dual connectivity mode or in a fast switching dual connectivity mode; and receiving, from the network, a dual connectivity configuration for the UE based at least in part on the indication of the capability. A second method includes communicating with a first network access device; transmitting, to a second network access device, a request to perform fast switching from the first network access device to the second network access device; receiving, from the second network access device, a dual connectivity configuration for communicating with the second network access device; and communicating with the second network access device based at least in part on the dual connectivity configuration.

摘要： A method for reordering data by an electronic device is described, including receiving a first set of data packets via a first radio access technology (RAT). The method also includes receiving a second set of data packets via a second RAT. The first and second sets of data packets are from a data stream. The method further includes providing at least a portion of the first set of data packets or of the second set of data packets to an application processor. The method additionally includes buffering, in application processor memory, the at least the portion of the first set of data packets or the at least the portion of the second set of data packets. The method also includes reordering the at least the portion of the first set of data packets or the at least the portion of the second set of data packets.

摘要： Aspects of the present disclosure provide mechanisms for count synchronization in a wireless communication network. A respective count value may be maintained for each packet transmitted over a wireless connection, where each count value includes a respective hyper frame number and a respective sequence number. To synchronize a current count value associated with a current packet, a count synchronization may be initiated to transmit at least a current hyper frame number of the current count value over the wireless connection.

摘要： Aspects of the present disclosure describe transmitting data in wireless communications. A set of packets for transmission in a defined sequence can be received where the set of packets includes two or more packets. It can be detected that a packet, of the set of packets, is a prioritized packet type. The packet can be prioritized for transmission ahead of its order in the defined sequence based on the detection of the prioritized packet type. The packet can be transmitted ahead of its order in the defined sequence to an access point.
