  • Patent number: 11146376
    Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE) may determine a duplexing configuration (e.g., frequency division duplexing (FDD) or time division duplexing (TDD)) of a carrier based on one or more synchronization signals. The UE may then receive a master information block (MIB) on the carrier, and may interpret one or more fields of the MIB based on the duplexing configuration of the carrier. The configuration dependent fields may include a special subframe field, a system information location field, or both. In some cases, such as in a TDD configuration, the UE may postulate a special subframe configuration of the carrier in order to receive the MIB, and may update the postulated special subframe configuration after receiving the MIB.

    Abstract: An electronic device may be provided with a dielectric cover layer, a dielectric substrate, and a phased antenna array on the dielectric substrate for conveying millimeter wave signals through the dielectric cover layer. The array may include conductive traces mounted against the dielectric layer. The conductive traces may form patch elements or parasitic elements for the phased antenna array. The dielectric layer may have a dielectric constant and a thickness selected to form a quarter wave impedance transformer for the array at a wavelength of operation of the array. The substrate may include fences of conductive vias that laterally surround each of the antennas within the array. When configured in this way, signal attenuation, destructive interference, and surface wave generation associated with the presence of the dielectric layer over the phased antenna array may be minimized.

  • Patent number: 11140714
    Abstract: Certain aspects of the disclosure relate to techniques and apparatus for improving random access for SRS switching in a wireless network. Prior to transmitting a SRS, a UE may interrupt communication on a first carrier to switch from the first carrier to a second carrier to transmit a PRACH. To reduce interruption to the first carrier, the UE may use the beginning symbol(s) of a UpPTS on the second carrier to transmit the PRACH. In addition, to reduce interruption to the first carrier, the UE may monitor for another PDCCH order before transmitting another PRACH. Further, aspects of the present disclosure provide techniques and apparatus for jointly triggering SRS transmissions and performing power control for SRS transmissions. A BS may trigger SRS transmissions from multiple UEs, trigger SRS transmissions from multiple carriers from the same UE at the same time and/or perform power control separately for each carrier.
