  • Patent number: 10644400
    Abstract: A host processor controls an apparatus by updating all the phase shifter values of a phased array antenna by using “global write” to update these parameters to all phased-array transformation circuits simultaneously via a serial bus. Antenna elements, each controlled by a phased-array transformation circuit, are individually configured to transform phase and gain according to a register array. The register array has a local register group and a central register group, the local registers physically placed close in proximity to RF chains which each correspond to an element of array antenna, whereby each set of local registers control an individual antenna element and a central register controlling overall beam steering function. The apparatus is transformed by the host efficiently elaborating phase shift weights into a submodule of a phase array antenna system with low noise and bandwidth. The host triggers reuse of phase and gain when it can.

  • Patent number: 10206181
    Abstract: Systems and methods for specifying UE power control allocation for simultaneous transmission of PRACH in a secondary serving cell and PUCCH/PUSCH/SRS in a different serving cell in another timing advance group are disclosed. Rules are provided for prioritizing transmission of PRACH and/or other UL channels/signals. Additionally, UE power allocation is controlled for misaligned subframes across different timing advance groups. Latency of UL synchronization for a secondary serving cell is reduced by prioritizing PRACH retransmission.
