Field: Digital communication (Electrical engineering)
Classification: CPC H | IPC H

Claim 0:
1. A radio node for Time Division Duplex, TDD, communications, the radio node comprising processing circuitry configured to:
inject a signal into a time window, the time window being positioned, in a time domain, between a TDD first direction subframe to a TDD second direction subframe, the time window having a time duration less than the TDD first direction subframe and TDD second direction subframe, the time window being part of an offset region that includes a time period in which the radio node is switchable from a receiving mode to a transmitting mode, the signal being configured such that a time headroom follows the injection of the signal into the time window, the time headroom having a duration configured to account for a timing uncertainty of a receiving radio node; and
perform at least one function using the injected signal.
