Abstract: Methods of operating an electronic device are provided. A method of operating a first electronic device includes listening for a wireless transmission by a second electronic device on a wireless communications channel. The method includes determining whether a packet is a particular type of packet. The method includes assigning a randomized time delay value that defines a randomized delay period, in response to determining that the packet is the particular type of packet. The method includes beginning the randomized delay period in response to determining that the wireless communications channel is clear. Moreover, the method includes transmitting the packet via the wireless communications channel based on expiration of the randomized delay period. Related electronic devices and computer program products are also provided.

Abstract: Method for operating a base station in a wireless radio network and base stationA base station (11) for a wireless radio network (10) comprises a plurality of antennas (12) for transmitting radio frequency signals between the base station (11) and a user equipment (16). The base station (11) receives at each antenna (12) of a subset of the plurality of antennas (12) training signals sent by the user equipment (16) and determines an antenna configuration parameter for each antenna (12) of the subset of the plurality of antennas (12) based on a combination (60-62) of the training signals received in a plurality of different frames (20) at the corresponding antenna (12) for a subsequent transmission of payload information (22, 23) between the base station (11) and the user equipment (16). The combination of the training signals of the different frames may include an averaging and/or a weighting of the training signals.
