    Abstract: A base station of a cellular radio communications network configured to operate in an unlicensed radio band, comprising a radio transceiver connected to an antenna, and a controller including a processor and a memory holding computer program code. The processor is configured to execute the computer program code to realize a machine for determining a size for a contention window, within which the base station may transmit data from the transceiver to a radio terminal operating in the network; receiving a signal from the terminal, comprising an indication of occupancy of a radio channel, as detected by the terminal; adjusting the contention window size dependent on the indication of occupancy of the radio channel; transmitting data to the terminal within the adjusted contention window.

    Abstract: A user equipment (10) is operable in a first mode in which the user equipment (10) is configured for communication with a first cellular network (30) and a second mode in which the user equipment (10) is configured for communication with a second cellular network (40). Mode switching between the modes is performed autonomously by the user equipment (10) or under the control of a cellular network node. The user equipment (10) has a first power consumption when operating in the first mode and a second power consumption when operating in the second mode, the second power consumption being different from the first power consumption.

    Abstract: A node (100) of a cellular network selects a first modulation scheme setting for a first radio link to a first device (10′). The first modulation scheme setting is selected from a set of modulation scheme settings, each identified by at least one corresponding index. On the basis of a mapping of each of the indices to a corresponding set of transmission parameters, the node (100) identifies a first set of link parameters mapped to the index corresponding to the selected first modulation scheme setting. The node (100) then configures the first radio link according to the identified first set of link parameters. Further, the node (100) selects a second modulation scheme setting for a second radio link to a second device (10).

    Abstract: Embodiments provide efficient channel access utilizing a channel assessment mode and include determining that a predetermined condition exists on a radio bandwidth (e.g., unlicensed band); and, in response to determining that the predetermined condition exists on the radio bandwidth, initiating the channel assessment mode on the mobile device, where the channel assessment mode is configured to implement a channel assessment scheme configured for efficiently accessing a channel on the radio bandwidth. Some embodiments monitor the radio bandwidth for one or more triggering events indicative of interference; and detect at least one of the one or more triggering events indicative of interference on the radio bandwidth in order to determine the predetermined condition exists. These triggering events may include determining a current/historic packet collision probability is above a threshold, detecting signals that identify another radio access system, detecting a channel utilization ratio above a threshold, and determining a current/historic data throughput.
