Methods, apparatuses and systems are provided for transmitting data. A method includes: sending a target random access preamble to a base station; receiving a target random access response that is sent by the base station based on the target random access preamble and carries repetition-number-indicating information; and transmitting, in accordance with a target transmission repetition number, the target uplink data to the base station during the random access procedure. The target transmission repetition number indicates a number of times the user equipment is configured to repeatedly transmit the target uplink data to the base station during the random access procedure. The target transmission repetition number is determined based on the repetition-number-indicating information and a target transmission block size. The target transmission block size is for the user equipment to transmit the target uplink data to the base station during the random access procedure.

Described are embodiments for Ethernet header compression. A base station sends, to a wireless device, a radio resource control message including a packet data convergence protocol (PDCP) configuration parameter indicating Ethernet header compression for a data radio bearer. Based on the PDCP configuration parameter, the base station sends, to the wireless device, a message including: a source medium access control (MAC) address and a destination MAC address, and a header compression index corresponding to the source MAC address and the destination MAC address. The base station sends, to the wireless device, a compressed Ethernet packet: including a packet header being compressed based on the message; and including the corresponding header compression index.

A network node obtains a message to be transmitted as a public warning system notification to multiple UEs, via one or more SIBs, and obtains area information corresponding to the message. The area information indicates an area for which the message is relevant. The network node determines how many SIBs are needed for transmitting the area information and segments the message into a plurality of segments, based on how many SIBs are needed for transmitting the area information. The network node transmits the message and the area information via SIBs, such that a segment of the message is included in each SIB and such that each portion of the area information included in a SIB is accompanied by a segment of the message. A UE receives the SIBs and assembles the message and area information, displaying the message if it is relevant.

A transmitting device includes a first layer processor configured to include a buffer to store therein transmission data, the first layer processor configured to execute processing for a first layer on the transmission data, a second layer processor configured to execute processing for a second layer that differs from the first layer on the transmission data, and a transmitter configured to transmit the transmission data processed by the first layer processor and the second layer processor. The first layer processor discards the transmission data stored in the buffer in accordance with a parameter used for transmission control in the processing for the second layer.
