  • Patent number: 10735156
    Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE) may indicate to a base station the number of uplink (UL) component carriers (CCs) that the UE is capable of supporting. A base station may configure the UE for carrier aggregation (CA) and for one or more auxiliary UL CCs. The CA configuration may include CCs for UL data transmissions and the auxiliary UL configuration may include CCs for UL reference signals or random access channel transmissions. The auxiliary UL CCs may thus be used for sounding reference signal (SRS) transmissions even if the UE is otherwise not configured for UL data transmissions on those CCs. UL data transmissions on the CA carriers may be sent at the same time as SRS transmissions or during different transmission time intervals (TTIs), depending on UE capability.

  • Patent number: 10659207
    Abstract: Aspects of the present disclosure implement techniques for power control management between the base station and the UE to support multiple waveforms and services. In one example, the power control management system may implement independent power control loops for each waveform and service (e.g., eMBB, uRLLC, etc.) supported by the wireless communication system. For example, the base station may transmit a first power control command to a UE for first waveform (e.g., CP-OFDM) or service (e.g., eMBB) and a second power control command to the UE for the second waveform (DFT-OFDM) or service (e.g., uRLLC). Features of the present disclosure may also implement techniques that allow the base station to transmit a single power control command for configuring the power control for a plurality of waveforms or services. Upon receiving the power control commands, the UE may configure the transmission power for uplink traffic based on the power control commands.

  • Patent number: 10660043
    Abstract: A user equipment (UE) may apply transmit power control (TPC) commands and transmit uplink information based on received downlink control information (DCI). A UE may receive multiple DCI messages including multiple TPC commands for an uplink transmission. The power level for the uplink transmission may be adjusted based on the combination of TPC commands. For example, the TPC commands may be considered together (e.g., added, averaged, etc.), the latest TPC command may be used, etc. In some cases, a change in TPC command for an uplink transmission (e.g., from a previous TPC command for the uplink transmission indicated via other DCI) may indicate a change in one or more transmission attributes for the uplink transmission. In some cases, a UE may receive a grant for a prioritized transmission, resulting in discontinuous transmission (DTX) of a previous transmission, which may result in TPC modification by the UE.

  • Patent number: 10630518
    Abstract: Methods, systems, and devices for wireless communication are described. Pilot ratios (e.g., a ratio of pilot (or reference signal) resources to a total number of resources) may be adapted based on various properties associated with transmissions between wireless devices. For example, a wireless device (e.g., a user equipment (UE) or a base station) may use different transmission configurations for transmitting messages that include reference signals and data. Based on the transmission configuration, the wireless device may determine an adjustable pilot ratio based on the transmission configuration. In some cases, the adjustable pilot ratio may be explicitly signaled, or may be implicitly determined based on the transmission configuration. For example, a wireless device may transmit (or receive) an indication of the pilot ratio, or the wireless device may determine the pilot ratio based on a transmission configuration used for communicating with the other wireless device.
