Abstract: A method for performing a listen-before-talk procedure in a first transceiver device (N1) for wireless electromagnetic communication in a frequency band (150) is disclosed. A first transceiver device (N1) configured to perform the method is also disclosed. The method comprises receiving at the first transceiver device (N1) a stream of data (11) from a second transceiver device (N2), and determining whether the second transceiver device (N2) is capable of receiving in only a single or in two polarization directions. If the second transceiver device (N2) is capable of receiving in two polarization directions, then the method comprises determining and using an energy threshold that is larger than a regulated energy threshold for listen-before-talk within the frequency band (150). If the second transceiver device (N2) is capable of receiving in only a single polarization direction or if the energy of the received stream of data (11) is smaller than the energy threshold, then constructing a signal to be transmitted within the frequency band (150) by the first transceiver device (N1).

Abstract: Method for allocating resources (44) within a grid (40) of time and frequency for communication in a radio communications system under a first protocol, comprising determining an indication of a frequency resource range (43) to be allocated for data communication between a base station and a device within the first radio protocol; determining that a predetermined frequency resource (42) within said range is pre-allocated to communication under a second radio protocol; allocating a frequency resource (44) for the communication in the first radio protocol which overlaps and excludes said predetermined frequency resource for that data communication.

Abstract: Network assistance is provided for the streaming of multi-segment data from a data source (12) to a streaming client (54) in a network. The network assistance for multi-segment data streaming may be carried out in an automated manner by the respective devices. The systems and methods include new functions that allow for more efficient handling of data segments that make up a data stream. The network assistance for multi-segment streaming may improve, for example, virtual reality (VR) streaming performance.

Abstract: A method comprises communicating, between a terminal (102) and a base station (101), an uplink control message (6001, 6003) of a random access procedure, the uplink control message (6001, 6003) comprising an indicator indicative of uplink payload data (6005, 6007) queued for transmission during the random access procedure. The method also comprises configuring the random access procedure depending on the indicator and communicating, in the random access procedure configured in accordance with the indicator, the uplink payload data (6005, 6007).

Abstract: Multi-beam multiplexing in mobile radio communication networks, specifically for initial network access transmissions, such as Random Access Channel (RACH) transmissions and other initial network access signals that affect the operation of the Random Access operation. A network node is configured to distribute, simultaneously, a plurality of beams across a predetermined coverage area. Each of the beams are associated with a different coverage area. In addition, a plurality of sub-carriers are precoded in an OFDM modulated signal, which includes control information, for the purpose of shaping (i.e., beamforming) each of the plurality of beams. In this regard, one or more sub-carriers are mapped to a beam.

Abstract: The invention relates to cell re-selection as a consequence of UE mobility in a scenario where coverage enhancement (CE) is employed for multiple repetitions of messages communicated on a wireless link between the UE and the network, and where a CE policy defines a repetition level. Accordingly, a communication device (130) receives at least one downlink control message (6031) from a base station (112, 112-1) of a source cell (181) of a network (100), the at least one downlink control message (6031) being indicative of access restrictions of a plurality of candidate cells (182, 183) of the network (100); more particularly, the at least one downlink control message (6031) is indicative, for each candidate cell (182, 183) of the plurality of candidate cells (182, 183), of at least one respective regulated repetition level. Based on the at least one downlink control message (6031), the communication device (130) selects a target cell (182, 183) from the plurality of candidate cells (182, 183); and communication between the communication device (130) and a base station (112, 112-2, 112-3) of the target cell (182, 183) is performed.
