  • Patent number: 11470592
    Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive signaling, such as a downlink control information (DCI), that identifies a transmission configuration state from a set of transmission configuration states, from which the UE may determine a receiver timing. The UE may then receive a downlink transmission, such as a physical downlink shared channel (PDSCH), from one or more transmission/reception points (TRPs). The UE may use the receiver timing to decode the downlink transmission by performing a fast fourier transform (FFT) with the receiver timing for the downlink transmission.

  • Publication number: 20220303912
    Abstract: Methods, systems, and devices for wireless communications are described that support techniques for transmission power determination for radio frequency (RF) exposure compliance. A transmitting device, such as a user equipment (UE) may determine an uplink transmit power limit for a time window based on an RF limit and a duration of the time window. The device may use the power limit to determine an uplink transmit power based on a computed uplink transmission period for the time window that accounts for a time period during which the device is expected to actually transmit. The computed uplink transmission period may be based on one or more actual uplink transmission periods during one or more prior time windows, a predictive model, network signaling, or any combinations thereof. The device may transmit one or more uplink transmissions during the time window using the determined uplink transmit power.

  • Publication number: 20220303783
    Abstract: Techniques and apparatus for channel mapping in shared spectrum in the presence of higher tier users are provided. One technique includes evaluating, for different channel locations of orthogonal channel(s) within available spectrum, an amount of transmission limitation imposed to a group of devices due to incumbent protection, an amount of available bandwidth, and/or a maximum contiguous channel size. A channel location is assigned to each orthogonal channel, based on the evaluation. Another technique includes determining first channel location(s) in order to assign at least a first orthogonal channel within available spectrum. Each first orthogonal channel is associated with a group of devices sharing bandwidth within one or more networks. An exchange is participated in with a network entity to share a first set of information associated with the first channel locations. A determination is made whether to modify portion(s) of the first set of information, based on the exchange.

  • Patent number: 11374638
    Abstract: Methods, systems, and devices channel quality indicator (CQI) reporting based on demodulation reference signal (DMRS) from a base station are described. In some cases, a base station may configure a user equipment (UE) with such DMRS based CQI reporting (e.g., by transmitting a CQI reporting configuration to the UE). The CQI reporting configuration may specify the UE is to report CQI based on DMRS and, in some cases, may configure the UE to report the CQI with hybrid automatic repeat request (HARQ) feedback. A UE may receive a control message that indicates a resource for reception of a downlink transmission and an uplink control resource for transmission of CQI information. The UE may identify a DMRS of the downlink transmission, calculate a CQI based on the DMRS, and transmit the calculated CQI to the base station via the uplink control resource indicated by the received control message.
