摘要： A fifth-generation wireless communications network includes a server node, radio network equipment and a wireless device. In an example method, a server node receives first user data in response to (i) the wireless device receiving from the radio network equipment information indicating a plurality of uplink access configurations, each uplink access configuration including a random access configuration; (ii) the wireless device receiving an uplink access configuration index; (iii) the wireless device using the uplink access configuration index to identify an uplink access configuration from among the indicated plurality of uplink access configurations, and (iv) the wireless device transmitting the first user data to the wireless communications network according to the identified uplink access configuration. In the example method, further, the server node initiates transmission of second and third user data. This causes the wireless device to (v) receive from the radio network equipment, in a first downlink subframe, a first OFDM transmission formatted according to a first numerology and carrying the second user data, and (vi) receive from the radio network equipment, in a second downlink subframe, a second OFDM transmission formatted according to a second numerology and carrying the third user data, wherein the numerologies have different subcarrier spacings.

摘要： There is provided a system for scheduled transmission from at least two network devices in a cellular communications network. The system comprises at least two network devices. Each respective network device is configured to transmit in sectors using directional transmission beams. The at least two network devices are configured to transmit in the sectors according to a beamforming pattern according to which concurrent received power from all but one of the at least two network devices in sectors in which more than one network device is enabled to transmit using the directional transmission beams is below a threshold interference power level.

摘要： There is provided mechanisms for precoding over a beam subset. A method is performed by a network node. The method comprises exchanging reference signal information for a set of transmission beams or set of antenna ports with a wireless device. The method comprises acquiring, based on the reference signal information, information regarding which proper subset of transmission beams from the set of transmission beams to use for communication with the wireless device. The method comprises determining precoding weights for the proper subset of transmission beams or antenna ports based on the reference signal information.

摘要： There is provided mechanisms for adaptive user-specific beam forming. A method is performed by a network node. The method comprises acquiring uplink user-specific spatial channel characteristics for a wireless device. The method comprises acquiring a set of downlink port mappings for the wireless device. The method comprises adaptively configuring user-specific ports for the wireless device by using the uplink user-specific spatial channel statistics to determine a downlink user-specific port mapping from the set of downlink port mappings, thereby providing user-specific beam forming for the wireless device.
