  • Method And Apparatus For Group Transmissions From Multiple Users To A Mobile Telecommunications Network
    Publication number: 20190312616
    Abstract: Methods and devices are proposed for enabling group transmission of data from a group of devices to a base station of a mobile telecommunications network. In order to enable beamforming for each of the group of devices, a plurality of unique antenna identifiers is assigned to each transmit antenna of the devices forming the beamforming group. The antenna identifiers are communicated to the base station. Each device of the beamforming group then transmits sounding reference signals to the base station with each transmit antenna identified with a unique identifier. The individual devices then receive respective beamforming precoding information, for each antenna identified with the unique antenna identifier, generated in response to a respective sounding reference signal from the base station. The devices then utilize the respective precoding information to transmit data to the base station as part of a joint beamforming transmission from the group of devices.

  • Methods and Devices for Scheduling Group Uplink Communication
    Publication number: 20190208539
    Abstract: Group transmission of data from a group of User Equipment devices to a network node of a cellular communication system where communication between devices is effected by device-to-device technology can provide significant improvements in uplink coverage and user bit rate. However, the benefits of group transmission means that not all devices of a group have sufficient network coverage to reliably receive a grant signal scheduling uplink resources from a network node. Methods, devices and a network node are proposed that enable the dynamic selection of either a direct grant mode, in which each device receives the uplink grant directly from the network, or a relayed grant mode, in which a device acting as group coordinator relays the grant to all members of the group, to ensure optimal performance for group transmissions. The selection is dependent on at least one determined condition relating to the group of devices and/or the group transmission.
