Techniques discussed herein can facilitate assisted indication of resource reservation in sidelink. One example aspect is a user equipment (UE), comprising: a memory interface; and processing circuitry communicatively coupled to the memory interface and configured to: generate a physical sidelink control channel (PSCCH) message related to a first stage sidelink control information (SCI), wherein the first stage SCI includes a first indication related to a SCI assistance request; and cause transmission of the first stage SCI.

A transmitting device maps complex valued symbols in sequence to physical resource blocks for a sidelink transmission. The transmitting device reserves a first symbol of a subframe, where resource elements in the first symbol of the subframe are not considered in mapping the complex valued symbols to the physical resource blocks for the sidelink transmission. The transmitting device transmits the sidelink transmission after mapping the complex valued symbols to the physical resource blocks. A receiving device receives the sidelink transmission and decodes the sidelink transmission to determine complex valued symbols that are mapped in sequence to physical resource blocks of the sidelink transmission, where the complex valued symbols are not mapped to resource elements in a first symbol of a subframe.

A method for managing an uninterrupted connection of a moving device to at least one attachment entity of at least one operator of a communication network. The method is implemented by a mediation entity capable of communicating with the at least one attachment entity. The method includes receiving a connection request comprising an identifier of the device and information relating to the movement of the device; determining at least one offer of connection to the at least one attachment entity on the basis of a communication feature, with the transmission of a proposal including the at least one determined connection offer. Determining, by the mediation entity, the connection of the device before its movement enables the movement of the device to be correlated with its connection and enables information relating to the operator or else to the mediation entity not to be disclosed.
