  • Publication number: 20200244324
    Abstract: In a closed-loop wireless communication system, a codebook-based feedback mechanism is provided to enable non-unitary precoding for multi-stream transmission, where each stream is optimized with suitable transmission power allocation and AMC. The codebook-based feedback mechanism uses a precoding codebook having a power allocation matrix which is constrained to specify that beamforming always applies full power to a predetermined beam. With this constraint, a one-bit power allocation feedback index may be used to switch between beamforming and spatial multiplexing.

  • Publication number: 20200169313
    Abstract: A wireless communication system non-collaborative, multiple input, multiple output (MIMO) space division multiple access (SDMA) system determines subscriber station combining and weighting vectors that yield a high average signal-to-interference plus noise ratio (SINR). Each subscriber station independently transmits information to a base station that allows the base station to determine a weight vector wi for each subscriber station using the determined combining vector of the subscriber station. The ith combining vector corresponds to a right singular vector corresponding to a maximum singular value of a channel matrix between a base station and the ith subscriber station. Each subscriber station transmits signals using a weight vector vi, which corresponds to a left singular vector corresponding to a maximum singular value of a channel matrix between the ith subscriber station and the base station. The base station uses the weight vector wi to determine the signal transmitted by the ith subscriber station.

  • Publication number: 20200153498
    Abstract: A base station is configured to provides a beam change feedback channel for a user equipment to communicate unsolicited beam change feedback to the base station. If the user equipment determines that a beam other than the beam to which the user equipment is tuned has a stronger signal, the user equipment initiates a transmission on the beam change feedback channel to the base station indicating a beam change. The base station uses the feedback from the user equipment to update the beam to the user equipment.

  • Patent number: 10555284
    Abstract: A system and method is disclosed for resource block-specific control signaling in a communication system. Communication data is transmitted using a transmission channel comprising a plurality of resource blocks defined by allocating time-frequency slots in a transmission resource. Resource block control information is transmitted in a “feed-forward” manner to a user end (UE) or group of UEs using channels physically mapped into scheduled resource blocks (RBs) for that user or group of users. Embodiments of the invention provide an RB-specific control channel that comprises RB control elements that are embedded within scheduled resource blocks. The invention, therefore, reduces the amount of control information that must be transmitted by common or shared control channels.

  • Patent number: 10277349
    Abstract: A millimeter-wave wireless multiple antenna system (200) is provided in which a UE (210) uses a multi-antenna subsystem (211) to sweep a plurality of receive beams (RX1-RXM) during each transmit beam in a plurality of transmit beams (TX1-TX64) used by the base station (201) to transmit an SSB, and then generates, for each receive beam, a received signal strength indicator (RSSI) value from samples of each transmitted SSB measured in said receive beam, thereby generating a plurality of RSSI values from which an optimal receive beam is selected based on a ranking of the RSSI values and then used to lock the UE (210) onto the optimal receive beam to perform a cell search which matches a transmit beam from the base station (201) to the optimal receive beam.
