Techniques providing opportunistic frequency switching for frame based equipment (FBE), such as may be configured to minimize opportunistic frequency switching delay in FBE new radio (NR) unlicensed (NR-U) networks and/or to provide frequency diversity FBE access based on offset sequences of medium sensing occasions for the carrier frequencies are disclosed. Within the FBE mode network, a base station may configure a pattern of sensing locations in each frame for each frequency transmission unit of the plurality of frequency transmission units, wherein an inter-unit delay of sensing locations between a first frequency transmission unit and a next adjacent frequency transmission unit and between a last frequency transmission unit and the first frequency transmission unit is a fixed duration. Opportunistic frequency switching of embodiments may utilize the medium sensing locations for opportunistically switching between a sequence of the frequency transmission units for implementing frequency diversity FBE access.

Multiple transmit and receive channels in a communication transceiver may be dynamically configured using corresponding channel registers. The present disclosure proposes a profile-based direct memory access (PDMA) that can be used to transfer data from a memory and program specific profile registers in a randomly accessed addressing manner. PDMAs can offload the system processor from reprogramming many system registers based on external or internal events in a multi channels communication system. Furthermore, a PDMA based DMA controller is proposed to configure the frequency hopping registers of the transceiver based on PDMA.
