Abstract: A 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) a training signal sent by the user equipment (16) in a first frame (20) and determines an antenna configuration parameter for each antenna (12) of the subset of the plurality of antennas (12) based on the training signal received in the first frame (20) for a subsequent transmission of payload information (33, 34) between the base station (11) and the user equipment (16) in a second frame (30) which is different from the first frame (20).

Abstract: First reoccurring resources on a radio interface of a cellular network (100) are allocated and shared between communication devices (121-125) assigned to a first set (151). Second reoccurring resources on the radio interface are allocated and shared between communication devices (121-125) assigned to a second set (152). A control message is sent, the control message indicating the first reoccurring resources and the second reoccurring resources. The control message may optionally be sent employing a broadcast transmission (110).

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.
