Radio resource management for full-duplex operation of integrated access and backhaul for 5g or other next generation network

Abstract

Integrate access and backhaul (IAB) nodes can multiplex access and backhaul links in time, frequency, or space, which includes the transmission of signals and/or channels utilized as part of initial access and measurements used for radio resource management (RRM). The same physical layer signals and channels used for these purposes by access a user equipment device can be reused for performing similar procedures at the IAB node. Consequently, the IAB node can leverage various muting patterns to employ the use of half-duplex and full-duplex synchronization signal block radio resource management such that mobile terminal functionality and distributed unit functionality of the IAB node can receive and transmit signals simultaneously.
