Abstract: Methods and apparatuses are provided in which an access point (AP) transmits a trigger frame to one or more user equipments (UEs). The trigger frame includes an indication of allocated resource units (RUs) for random access (RA). A UE allocates respective data to a sets of RUs for RA that are consecutive in a single frequency segment over a time domain of a physical protocol data unit (PPDU), based on the trigger frame. The UE transmits the PPDU to the AP.

Abstract: An electronic device configured to apply, to a first power amplifier (PA) input, one or more updated memory digital pre-distorter (mDPD) coefficient values is provided. The electronic device includes a processor; and a memory including a non-transitory computer readable storage medium storing instructions that, when executed, cause the processor to preload, from values stored in the memory of the electronic device, one or more mDPD coefficient values; transmit a training signal sequence while using the preloaded one or more mDPD coefficient values; receive the training signal sequence; update the one or more mDPD coefficient values based on the transmitted training signal sequence, the received training signal sequence, and the preloaded one or more mDPD coefficient values; and apply the updated one or more mDPD coefficient values to distort the first PA input.
