摘要： 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.

摘要： 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.

摘要： 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.

摘要： The invention is directed to systems, methods and computer program products for switching to a machine type communication (MTC) coverage enhancement mode on a network. An exemplary method comprises determining a signal quality for a signal from the network; determining the signal quality is below a threshold quality level for using Long-Term Evolution (LTE) protocol to communicate with the network; in response to determining the signal quality is below the threshold quality level, switching the device to the MTC mode and communicating with the network using MTC specification of the LTE protocol, wherein the device comprises a non-MTC device.

摘要： 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.

摘要： Streaming content with an electronic device includes incrementally downloading content data at a first quality level from a content server over a network. Triggered by receipt of a notification indicative of predicted network congestion, the electronic device requests and downloads a next increment of the content data at a second quality level lower than the first quality level from the content server.
