Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a transmitter device may determine whether a packet, to be transmitted by the transmitter device, is compressed; generate a header for transmission of the packet based at least in part on the determination, wherein the header includes a context identifier indicating whether the packet is compressed; and transmit the packet and the header. Numerous other aspects are provided.

A packet sending method includes, when a network element in a serial network receives a to-be-forwarded packet at a previous node from a previous network element, and when the network element needs to send a to-be-sent packet at a current node, determining whether the to-be-sent packet at the current node and the to-be-forwarded packet at the previous node can be superimposed, where the network element is an intermediate network element in the serial network; when the to-be-sent packet at the current node and the to-be-forwarded packet at the previous node can be superimposed, superimposing the to-be-sent packet at the current node and the to-be-forwarded packet at the previous node, to obtain a to-be-forwarded packet at the current node; and sending the to-be-forwarded packet at the current node to a next network element of the network element.

A fronthaul multiplexer according to one aspect of the present invention combines uplink packets in a compressed state that is received from two or more radio units so that the uplink packets are accumulated and combined immediately when received or the uplink packets are recompressed using a compressing method with high compression efficiency when stored in a memory in order to reduce a use amount of memory.

Systems, apparatuses, and methods are described for wireless communications. A base station and wireless device may communicate capability information associated with a wireless device. The capability information may include information indicating support for an Ethernet type packet data unit session or header parameter compression. An Ethernet type packet data unit session may be instantiated based on the capability information.

A method, device, and system for network traffic analysis are provided. The method comprises obtaining traffic data of current time interval, recording the traffic data in a Chinese Remainder Theorem based Reversible Sketch (CRT-RS) based on a hash operation comprising Modulo operations, detecting abnormal buckets in the CRT-RS based on a change between the traffic data of current time interval and traffic data of previous time interval, and recovering abnormal source address associated information based on the abnormal buckets, wherein the modulus of the Modulo operations are selected from the modulus in Chinese Remainder Theorem (CRT) as pairwise coprime integers and the CRT-RS includes a plurality of buckets. The step of detecting uses a Modified Multi-chart Cumulative Sum.

A transmitting apparatus is provided. The transmitting apparatus includes: a packet generator generating a packet including a header and a payload from an input stream including a plurality of input packets; and a signal processor signal-processing the packet, wherein the header includes a base header which includes: a first field indicating a packet type of the input packets; wherein when the first field is set to a value indicating that the packet type of the input packets is a TS packet, the base header comprises a second field indicating a number of TS packets included in the payload and a third field set to a first value indicating that the header of the packet does not comprises an additional header or a second value indicating that the header of the packet further comprises the additional header, and wherein the third field is set to the second value when TS header compression to remove at least one header of the TS packets is applied to generate the packet.
