Abstract: In a wireless communication system, an APM provides sequential numbers to channels formed by dividing a specific frequency band, selects the channels in bit-reversed order of the numbers to divide the channels in frequency groups, creates a small hopping table for each frequency group, and generates a hopping table using the plurality of small hopping tables, and an AP performs channel access to a STA by frequency hopping with reference to the hopping table.

Abstract: Multiple transmit and receive channels in a communication transceiver may be dynamically configured using corresponding channel registers. In order to support fast frequency hopping, arbitrary sample rate change or profile switching, 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 fast frequency hopping registers of the transceiver based on PDMA.

Abstract: In some aspects, a channel hopping sequence for communication on a mesh network is generated. The hopping sequence may include multiple channels assigned to respective positions in the hopping sequence. In some cases, a first channel is assigned to a first position such that the first channel may transmit communications in a first transmission mode, such as a low-bandwidth transmission mode. In addition, an additional channels adjacent to the first channel is also assigned to the first position such that the combination of the first channel and additional channel may transmit communications in a second transmission mode, such as a high-bandwidth transmission mode. In some cases, a whitelist is determined based on the assigned channels. The whitelist may indicate channels that do not conflict with the assigned channels during transmission of a communication. In addition, channels may be assigned to the hopping sequence based on the whitelist.
