Abstract: Methods, a user equipment (UE) and a base station are disclosed for sidelink identification. According to an embodiment, a first UE participates in an identity (ID) determination procedure such that a sidelink ID is determined for a sidelink between the first UE and a second UE. The sidelink ID comprises a full ID for identifying one of the first and second UEs and a short ID for identifying the other of the first and second UEs.

Abstract: A method in a first node (610, 615) is disclosed. The method comprises determining (704) a time resource over which the first node transmits a signal to a second node (610, 615). The method comprises signaling (708), to at least one of the second node or a third node (610, 615), information about one or more transient time parameters associated with the time resource, wherein the one or more transient time parameters are used by the first node for transmitting the signal to the second node during the time resource. The method comprises adapting (712) a transmitter configuration of the first node for transmitting the signal to the second node based on one of the one or more transient time parameters.
