  • Patent number: 11546025
    Abstract: Certain aspects of the present disclosure provide techniques for precoding for multi-panel uplink transmission. For codebook-based uplink transmission, a user equipment (UE) can determine one or more preferred or selected precoders for uplink transmission. The precoders can be from an expanded UE codebook that maps a first number of transmit layers at the UE to a second number of antenna ports at the UE, the layers and/or antenna ports associated with multiple uplink transmit panels at the UE. The UE sends an indication to a base station (BS) of the determined precoders and/or sends an uplink transmission using the determined precoders. For non-codebook based uplink transmission the UE receives first and second reference signals (RSs), from first and second ports of a BS, with first and second UE antenna panels. The UE computes precoders to use for uplink transmission based on the RSs.

  • Patent number: 11546046
    Abstract: Systems, apparatuses, and methods for enhancement for amplify-and-forward relay. Instead of merely passing received signal from a source, relay may equalize the received signal based on reference signal contained in the received signal, before amplifying and transmitting the signal to a destination. Compared to amplify-and-forward, equalize-and-forward may compensate the received source signal for various imperfections such as channel distortions and phase errors, using demodulation reference signal and phase tracking reference signal. The relay may apply Fast Fourier Transform (FFT) to equalize the signal in tone domain.

  • Patent number: 11540150
    Abstract: Systems, methods, and apparatuses for performing a beam recovery procedure using a second CC are disclosed. A UE may perform a beam recovery procedure using two component carriers (CCs): for example, first component carrier may be a beam formed millimeter wave (MMW) carrier having a beam recovery procedure and second component carrier may be an assisting carrier such as a sub-6 GHz carrier or a different MMW carrier. In a first example, a UE may trigger beam recovery for first component carrier (on second component carrier), generate a beam measurement report, and transmit the beam report on resources allocated for uplink transmission on second component carrier. In a second example, a new scheduling request (SR) may be defined on first component carrier for second component carrier beam recovery. In a third example, RACH resources or procedures on second component carrier may be used to perform the beam recovery for first component carrier.
