20200412434 | UE BEAM DETECTION - Methods, systems, and devices for wireless communications are described. A user equipment (UE) may performing a search procedure using a first receive beam. The UE may detect, based on performing the search procedure, a synchronization signal block corresponding to a transmit beam in a first synchronization signal burst set transmitted by a base station. The UE may perform a measurement procedure on a second synchronization signal burst set using a second receive beam to measure the transmit beam, where the second synchronization signal burst set is transmitted subsequently to the first synchronization signal burst set. In some cases, the UE may perform a measurement procedure for each configured receive beam. The UE may perform a beam refinement procedure after measuring each configured receive beam. | 2020-12-31 |
20200412435 | ALLOCATION AND DIRECTIONAL INFORMATION DISTRIBUTION IN MILLIMETER WAVE WLAN NETWORKS - A wireless communication apparatus, system or method utilizing directional data transmission over a communication (e.g., mmW) band, and broadcasting time and directional allocations in each direction. Stations sending beacons containing time and directional allocations in its direction of transmission. Stations comparing beam identifications with received allocation to determine if the allocation is in the direction of reception. Stations performing receiver beamforming with a station from which a beacon was received in order to determine if the station can access the direction (channel) in its intended direction. | 2020-12-31 |
20200412436 | Switching Bandwidth Parts Based On Beam Failure Recovery Configuration - A wireless device switches from a first downlink bandwidth part (BWP) to a second downlink BWP identified with a downlink BWP index. Based on the second downlink BWP being configured with beam failure recovery (BFR), a first uplink BWP is switched to a second uplink BWP identified with a uplink BWP index that is the same as the downlink BWP index. The second downlink BWP is switched to a third downlink BWP. Based on the third downlink BWP not being configured with BFR, the second uplink BWP is kept as an active uplink BWP. | 2020-12-31 |
20200412437 | Aborting a Beam Failure Recovery Procedure Based on an Expiry of a Time Alignment Timer - A wireless device receives configuration parameters indicating a time alignment timer of a timing advance group comprising a cell. The time alignment timer is started in response to receiving a timing advance command for the timing advance group. The wireless device transmits an uplink signal for a beam failure recovery procedure for the cell based on a beam failure of the cell. The beam failure recovery procedure is aborted based on an expiry of the time alignment timer during the beam failure recovery procedure. | 2020-12-31 |
20200412438 | SYSTEMS AND METHODS FOR SELECTING RADIO BEAMS - A device may obtain, from a user equipment (UE), first information relating to one or more signal strengths measured by the UE. A signal strength of the one or more signal strengths may be associated with a beam of a radio node. The device may identify, based on the first information, a particular signal strength that is associated with a particular beam. The device may select, based on the particular beam, one or more related beams that are associated with the particular beam. The one or more related beams may be associated with the particular beam based on historical data relating to historical signal strengths measured by a plurality of UEs. The device may provide, to the UE, second information that identifies the one or more related beams selected, to permit the UE to communicate using the one or more related beams. | 2020-12-31 |
20200412439 | DIVERSITY POLARIZATION MODULATION - A method includes transmitting a digital code from a transmitter to a receiver. Information is transmitted via electromagnetic waves from the transmitter to the receiver. The transmission of the information includes transmitting a first portion of the information using electromagnetic waves with a first polarization in response to a first value of the digital code, and transmitting a second portion of the information using electromagnetic waves of a second polarization in response to a second value of the digital code. The first information may include a first navigational code and the second information may include a second navigational code. | 2020-12-31 |
20200412440 | SELECTION, DIVERSITY COMBINING OR SATELLITE MIMO TO MITIGATE SCINTILLATION AND/OR NEAR-TERRESTRIAL MULTIPATH TO USER DEVICES - A ground station processes downlink signals received from respective satellites. The ground station has a plurality of signal conditioning devices each receiving a respective one of the downlink signals and providing a conditioned downlink signal. A plurality of Doppler and/or Delay compensator devices each receive a respective conditioned downlink signal from a respective one of the plurality of signal conditioning devices. The compensator devices conduct Doppler and/or Delay compensation on the received conditioned downlink signal, and provide a compensated downlink signal output. A selector or diversity combiner receives the compensated downlink signal from each of the plurality of Doppler and/or Delay compensators. The selector or diversity combiner selects one of the received compensated downlink signals based on received signal strength of each received compensated downlink signal to provide a selected downlink signal, or diversity combines all of the received compensated downlink signals to provide a diversity combined signal. The selector or diversity combiner provides the selected downlink signal or the diversity combined signal to an eNodeB. | 2020-12-31 |
