  • REPETITION TECHNIQUES FOR AUTONOMOUS UPLINK TRANSMISSIONS
    Publication number: 20220376845
    Abstract: Methods, systems, and devices for wireless communications are described that provide improved repetition techniques for autonomous uplink transmissions. Configuration information may be provided from a base station to a user equipment (UE) for autonomous uplink transmissions, that may indicate initial resources for an initial uplink transmission slot and retransmission resources for a number of retransmissions. Time resources within the retransmission resources may be configured to provide enhanced reliability, such as by being configured in non-contiguous slots to avoid one or more other transmission channels. Time resources within slots may also be configured to prevent persistent collisions with autonomous uplink transmissions or retransmissions of two or more different UEs.

  • Round-trip-time (RTT)-based positioning with listening nodes
    Patent number: 11490354
    Abstract: Disclosed are techniques for positioning a user equipment (UE). In aspects, a listening node determines a first time of arrival (ToA) at the listening node of a first radio frequency (RF) signal sent by a transmission-reception point (TRP) to the UE, determines a second ToA at the listening node of a second RF signal sent by the UE to the TRP, determines a time difference between the first ToA and the second ToA, and enables a positioning entity to estimate a location of the UE based on the time difference. The positioning entity calculates a distance between the listening node and the UE based on the time difference, a propagation time between the TRP and the listening node, a propagation time between the TRP and the UE, and a time difference between a ToA of the first RF signal at the UE and a transmission time of the second RF signal.

  • LOCATION ASSISTANCE DATA WITH LINE OF SIGHT CONDITION FOR A LINK BETWEEN A USER EQUIPMENT AND A WIRELESS NETWORK NODE
    Publication number: 20220312153
    Abstract: Disclosed are techniques for wireless communication. In an aspect, a user equipment (UE) transmits a first signal for positioning (RS-P) (e.g., SRS, etc.) on a first link from the UE to a wireless network node (e.g., BS, UE, etc.). The UE receives, from the wireless network node, location assistance data that comprises information that indicates a line of sight (LOS) condition associated with the first link. The UE measures a second RS-P on a second link from the wireless network node to the UE that is reciprocal to the first link. The UE performs one or more positioning measurements, determines a location estimate of the UE, or both, based in part on the reception of the second RS-P on the second link and the indicated LOS condition, the indicated LOS condition associated with the second link based on link reciprocity between the first and second links.

  • Discontinuous reception techniques with non-uniform cycle durations
    Patent number: 11452165
    Abstract: Methods, systems, and devices for wireless communications are described for configuring discontinuous reception (DRX) cycles within a DRX time period at a user equipment (UE).

  • Antenna port compatibility signaling
    Patent number: 11445361
    Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE) capable of supporting multiple antenna ports may determine that some combinations of antenna ports can be used simultaneously. The UE may make this determination by evaluating the relationships between the physical antennas and the transmit chains included in the UE. Upon determining that the combinations of antenna ports can be used simultaneously, the UE may send a message to a base station. The message may indicate whether two or more antenna ports can be used at the same time. The UE may communicate simultaneously over one or more antenna ports based on the scheduling information from the base station which takes into account the ability of the combination of antenna ports to be used concurrently.

  • Scheduling requests for grant-free configurations
    Patent number: 11425746
    Abstract: Generally, the described techniques provide for a user equipment (UE) generating a scheduling request (SR) for a set of data for an uplink transmission from the UE to a base station. The UE may determine whether the SR for the set of data is associated with a grant-free configuration for the UE. The grant-free configuration may indicate a set of time-frequency resources that the UE may use to transmit the set of data. The UE may transmit to the base station an indication of whether the SR is associated with the grant-free configuration. If the SR is associated with a grant-free configuration for the UE, the UE may use the corresponding resources to transmit the set of data to the base station, and the base station may then decode the data based on having received the indication of the resources by way of the grant-free configuration.
