The method, apparatus and computer program product determine whether traffic redundancy is needed for the radio access network and the user plane function based on the traffic redundancy indication. The method, apparatus and computer program product request the radio access network to not establish redundancy mechanisms in a circumstance where traffic redundancy is not needed for the radio access network. The method, apparatus and computer program product request the user plane function to not establish redundancy mechanisms in a circumstance where traffic redundancy is not needed for the user plane function.

A method for data communication between communication participants including observing the surroundings of the transmitting participant, determining the positon and motion of the communication participants, and estimating the transmission conditions at a later point in time. The solution is based on classifying the data for data communication in different categories, the categories determining susceptibility of the data to transmission errors determining which data is transmitted under good transmission conditions only and which data is be transmitted under rough transmission conditions whereby the transmission station plans the transmission of data in different categories. The method further includes selecting for data transmission at a given time for which the transmission conditions have been estimated so the data to be transmitted is in a category fitting to the estimated transmission conditions based on the categories data, and transmitting the selected data.

In a first device incorporating a processor and a memory in communication with the processor, the memory includes executable instructions that, when executed, cause the processor to control the first device to perform functions of receiving a bit error pattern of data traffic transmission from the first device to a second device, the bit error pattern including a number and locations of bit errors which occurred during the data traffic transmission; and adapting at least one transmission parameter of the first device based on the received bit error pattern. The error pattern allows more refined data traffic decisions.

A user equipment (e.g., C-V2X user equipment) can receive a transmission from a network device of a mobile network and decode the transmission using a first forward error correction code. The user equipment can determine an attribute of the transmission to determine a condition of the communication channel. Based on the condition of the communication channel, the user equipment can facilitate transmitting feedback to the network device, wherein the feedback is forwarded through the mobile network to an application server device that selects a second forward error correction code based on the feedback. The second forward error correction code can be transmitted to, and received by, the user equipment. The user equipment can use the second forward error correction code to decode subsequent transmissions.

The present disclosure relates to an operation method for a transmitter in a wireless communication system, the operation method comprising the steps of: mapping a parameter according to quality of service (QoS) information or a service type; determining, on the basis of the parameter, whether to duplicate a packet; when it is determined that the packet is to be duplicated, duplicating the packet; and transmitting the duplicated packets to a receiver.

The proposed embodiment provides an efficient way to implicitly detect at the receiver the puncturing information (i. e. time/frequency resources, MCS, TBS etc.) of the Ultra Reliable Low Latency Communication (URLLC) in the punctured Enhanced Mobile Broadband (eMBB) area. The performance of eMBB traffic can be improved by implicitly providing the puncturing information without any additional signaling or indications (e.g. does not require any additional bits).

Various solutions for processing timeline enhancement with respect to user equipment and network apparatus in mobile communications are described. An apparatus may determine whether a latency requirement of a service is less than a threshold value. The apparatus may use a first processing time capability to perform a transmission in an event that the latency requirement of the service is not less than the threshold value. The apparatus may use a second processing time capability to perform the transmission in an event that the latency requirement of the service is less than the threshold value. The apparatus may apply a scheduling restriction/optimization to perform the transmission when using the second processing time capability.

Systems and methods are introduced for rate control of data transmissions in a wireless camera system. In an illustrative embodiment, a computing system selects primary data rates and corresponding fallback data rates to use for transmission of video data. The computing system selects the data rates that provides high-throughput without resulting in wasted energy from retransmissions. The selection may be based upon transmission conditions as well as the record of past data rates, the number of attempts for the data rates, and whether they were successful. These data may be stored as a state machine or for machine learning analysis. Finally, the video data may be aggregated prior to transmission to reduce overhead and improve efficiency.
