Abstract: Methods and system for using a multifunctional filter to minimize insertion loss in a multi-mode communications system are described. Specifically described is a multifunctional filter that is configurable to operate in a band-pass mode when a first type of signal is propagated through the multifunctional filter, and to operate in a low-pass mode when a second type of signal is propagated through the multifunctional filter. The multifunctional filter presents a lower insertion loss to the second type of signal when operating in the low-pass mode than in the band-pass mode.

Abstract: The random access channel procedure for new radio NR can be designed to support multiple use cases with various requirements. The NR physical layer can support the independent configuration of resources used for the random access channel (RACH) procedures that can be transparent to user equipment (UE) devices and independent from resources configured for the UE. For instance, in the case of a standalone NR the RACH configuration can be obtained by the UE by either signaling on the NR carrier or fixed within the telecommunications standard. While in the case of non-standalone NR the RACH configuration can be obtained by the UE by broadcast or dedicated signaling on a different carrier than the NR carrier (e.g. a Long Term Evolution carrier).

The method generally includes performing communications, in a first channel, on a first downlink in a first time period based on communications in a second channel adjacent to the first channel being performed on a second downlink in the first time period.

The method further includes refraining from communicating in the first channel on one or more resources in the first time period or the second time period to mitigate cross-link interference with a third channel adjacent to the first channel.
