Abstract: A method and apparatus are provided. The method includes receiving, by a user equipment (UE), a first signal from a transceiver, determining one of a probability and a soft mean with a soft variance associated with the detected data symbol, determining a first coefficient and a second coefficient based on the determined one of the probability and the soft mean with the soft variance associated with the detected data symbol, determining channel state information (CSI) on a channel between the transceiver and the UE based on a second signal received by the UE from the transceiver, a previous CSI, the first coefficient and the second coefficient, and tracking the communication channel based on the determined CSI.

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.

Abstract: A system and method for selecting values for Validate and Disregard bits. In some embodiments, the method includes: receiving, by a first wireless station, from a second wireless station, an information element reporting capabilities of the second wireless station; and determining, by the first wireless station, based on the information element, whether to transmit, to the second wireless station, a default value for each of a plurality of Validate bits and for each of a plurality of Disregard bits.
