  • Publication number: 20220210612
    Abstract: Apparatus, methods and computer program products for user equipment positioning solutions and related signalling. An apparatus comprising at least one processor and at least one memory including computer program code, the at least one memory and the computer program code are configured, with the at least one processor, to cause the apparatus to at least send (550), to a network node of a communication network, at least one signaling configuration with at least one set periodicity, wherein the at least one signaling configuration is for use at the network node in calculating at least position information for relaying to the communication network at least for positioning support of the apparatus, and receive (570) the positioning support from the communication network in response to the at least one signaling configuration.

  • Patent number: 11191095
    Abstract: An uplink non-orthogonal multiple access for narrowband machine type communication used for the deployment of Internet of Things (IoT) interconnected devices where one or more user equipment are configured for uplink transmission with one or more uplink time-frequency regions for enhanced Machine Type Communication Non-Orthogonal Multiple Access. The configuring is based on defining and signaling one or more signal thresholds and one or more of a resource assignment, a starting subframe periodicity, a starting subframe offset, a time duration in each period, a demodulation reference signal cyclic shift assignment, orthogonal cover code assignment, and interleaver assignment.

  • Patent number: 10498410
    Abstract: Systems, methods, apparatuses, and computer program products for determining transmit weights are provided. One method includes selecting users to pair for multi-user multiple input multiple output transmission, calculating multi-user multiple input multiple output (MU-MIMO) transmit weights in a communication system employing an analog electrically steered array with Q antennas, applying the multi-user multiple input multiple output weights to the transmitted signals, and transmitting the weighted signals from an antenna array. The calculating may include calculating the MU-MIMO transmit weights so that a sum of power across a same element of the selected users' weight vectors is equal on all of the antennas and one of either sum throughput across users or sum signal to interference plus noise ratio (SINR) across users is maximized.
