Abstract: In a vehicle to anything environment, in order to achieve good data reception, receiving equipment and transmission equipment are preconfigured and thus include all the parameters needed for data transmission. In order to increase the probability of the data being received by the receiving equipment, the transmission equipment uses a highly robust modulation and coding scheme to code and modulate the radio signal used to broadcast the data. However, the more robust the implemented modulation and coding scheme, the lower the spectral efficiency of the radio signal used for transmission. User equipments belonging to the same broadcast group are identified by means of an identifier of the broadcast group, which allows for the implementation of a mechanism of acknowledgement by the receiving equipments making it possible to inform the transmission equipment that an error has occurred in the reception of the broadcast data.

Abstract: Methods, systems, and devices for wireless communications are described. Generally, a user equipment (UE) may transmit feedback signaling for received sidelink messages to both the base station and the transmitting UE. The receiving UE may multicast a feedback message to both the base station and the transmitting UE on a physical uplink control channel (PUCCH) or on a physical sidelink feedback channel (PSFCH). The base station may configure the receiving UE with resources, the transmitting UE may allocate resources to the receiving UE, or the base station may actively monitor for the feedback message. In some examples, the receiving UE may operate in a dual connectivity mode, and may transmit the feedback message to both the base station and the transmitting UE on both the PUCCH and the PSFCH.

Abstract: In a rule based header compression system such as a SCHC compressor/decompressor, a controller is provided which provides “hints” to the header compression processor, so as to direct its behaviour. These hints may define new rules, modify existing rules, set state values against which rules are tested during compression, prioritise rules or exclude rules from consideration to achieve optimum compression. The controller may dynamically generate rules on the basis of learned of detected flow characteristics to achieve optimum compression. The controller may operate as a state machine, which may define states corresponding to different degrees of compression for a given flow or flow type. The system comprises multiple compressors, some or all of which may be remote from the compression processor.
