  • Patent number: 11330604
    Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive a first slot format configuration for a first cell associated with a first radio access technology (RAT) and a first radio frequency spectrum band that conflicts with a second slot format configuration for a second cell associated with a second RAT and a second radio frequency spectrum band during at least a portion of a transmission time interval (TTI). The UE may determine that the first cell has a priority over the second cell, based on the configured slot formats or based on the radio frequency bands, and may drop a communication on the second cell based on the identified priority. The UE may then communicate during at least a portion of the TTI on the first cell while the UE drops a communication on the second cell.

  • Patent number: 11330565
    Abstract: Aspects of the present disclosure propose a mechanism whereby a nearby device may detect scenarios where one device is unable to receive communications from a transmitting device. For example, the nearby device may detect that concurrent transmissions of a transmitting device and intended recipient prevent reception by the intended recipient and provide feedback to the transmitting device. Rather than blindly retransmitting, the transmitting device may only retransmit when it receives feedback from the nearby device, saving power and avoiding unnecessary transmissions.

  • Patent number: 11330639
    Abstract: Methods, systems, and devices for wireless communications are described that support different, or adjusted, random access channel (RACH) preamble formats for efficient use of shared RACH time-frequency resources. The described techniques provide for assigning different RACH preamble formats to wireless devices that have a higher link budget, whereupon the devices may transmit the different RACH preamble using the link budget available to them in one or more RACH transmission opportunities in the shared RACH time-frequency resources. Such methods, systems, and devices may allow for more RACH transmission opportunities, as well as less interference between RACH transmissions.

  • Patent number: 11330467
    Abstract: There may be a gap between the time a beam pair link (BPL) impacted by a beam failure (BF) event is deactivated and the time a replacement BPL is activated and becomes fully functional at a UE. The gap may be called a blackout period. A base station may not know the blackout period and may continue transmitting to the UE on the impacted BPL during the blackout period. This may result in a transmission failure. Disclosed herein are apparatus and methods for determining a blackout period associated with a beam failure (BF) event and communicating a blackout indication to a base station, the blackout indication including the blackout period.

  • Patent number: 11330550
    Abstract: Methods, systems, and devices for wireless communications are described. A position of a user equipment (UE) may be determined when communications between the UE and a base station are routed through a relay node. For example, the UE 115 may determine whether communications are received from the base station or the relay node based on positioning assistance data that contains positioning-related information about different base stations and relay nodes in the system. The UE may then transmit a position metric based on this determination, where a location server uses this position metric for determining the location of the UE. Additionally or alternatively, the location server or base station may use the positioning assistance data to determine whether an uplink transmission is received directly from the UE or via the relay node and may generate a position metric that the location server uses for determining the location of the UE.

  • Patent number: 11330619
    Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE) and a base station may use low latency communications to improve the throughput of a wireless link. To facilitate efficient low latency communication, the UE may send UE-initiated CSI reports in addition to periodic and base station-initiated reports. For example, the UE may, in various examples, send UE-initiated CSI reports using contention based spectrum, using a request-to-transmit, or using a CSI differential (i.e., an indicator of a change in channel conditions). The base station may schedule different UEs for uplink low latency communication by providing resources to each UE for CSI and scheduling requests (SRs) using coherent or non-coherent uplink transmissions. The CSI and SR may also be combined with uplink feedback.
