  • Patent number: 11140641
    Abstract: Aspects directed towards synchronizing out of coverage (OOC) vehicle-to-everything (V2X) communications are disclosed. In one example, a scheduled entity detects a loss of a synchronization signal associated with a V2X communication by detecting when a timing uncertainty value or error value is greater than a threshold value. Packet timing information is then received in response to the loss of the synchronization signal from at least one user equipment (UE) synchronized with the synchronization signal. The scheduled entity then maintains the V2X communication by performing a timing adjustment based on the packet timing information.

  • Patent number: 11129109
    Abstract: Methods, systems, and devices for wireless communications are described for handling uplink grants that have associated uplink transmission that may exceed exposure limits. Exposure limits may be based on maximum permissible exposure (MPE) limits of millimeter wave transmissions and may be determined at a user equipment (UE) and provided to a base station. If the UE receives an uplink grant for a transmission in which an associated uplink transmission would exceed the exposure limits, the UE may drop the uplink transmission prior to forming a transport block, transmit control signaling to the base station to indicate the exposure limits at the UE, or combinations thereof.

  • Patent number: 11082920
    Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may identify a set of base stations that are part of a synchronization group, where at least two of the base stations in the set of base stations operate on different frequencies. In some cases, the UE may identify the set of base stations based on an indication transmitted by a serving base station for the UE. Additionally, once the synchronization group is identified, the UE may schedule synchronization signals together from the set of base stations. For example, after identifying the set of base stations, the UE may identify a measurement timing window associated with the synchronization group and measure a respective synchronization signal for each base station within the measurement timing window. Accordingly, the UE may then transmit a measurement report to the serving base station that includes the synchronization signal measurements.

  • Publication number: 20210176013
    Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may adaptively switch between hybrid automatic repeat request (HARQ) monitoring modes to support power savings. In a first HARQ skipping mode, the UE may transmit an uplink message corresponding to a HARQ identifier and may receive a positive acknowledgment (ACK) message in a HARQ monitoring occasion associated with the HARQ identifier. Upon receiving the ACK message, the UE refrains from monitoring a subsequent HARQ monitoring occasion associated with the HARQ identifier while in the first HARQ skipping mode (e.g., an aggressive HARQ skipping mode). The UE may periodically enter a periodic evaluation mode from the first HARQ skipping mode, in which the UE monitors a subsequent HARQ monitoring occasion after receiving an ACK message to check for false ACK messages. If a false ACK message is detected, the UE enters a first HARQ skipping prohibited mode.

  • Publication number: 20210160942
    Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine whether a slot timing difference, between a first cell and a second cell for a dual connectivity mode, satisfies a threshold value, where the first cell is a serving cell associated with a first radio access technology (RAT) and the second cell is a serving cell or a candidate cell associated with a second RAT. The UE may perform an operation to prevent the dual connectivity mode with the second cell, establish the dual connectivity mode with the second cell, maintain the dual connectivity mode with the second cell, or terminate the dual connectivity mode with the second cell based at least in part on whether the slot timing difference satisfies the threshold value. Numerous other aspects are provided.

  • Publication number: 20210120501
    Abstract: This disclosure provides systems, methods and apparatuses for user equipment (UE)-side and network-side mitigation of intermodulation (IM) interference, such as IM interference associated with multi-radio access technology communications. For example, the UE or a base station may detect an IM interference condition, and may perform an IM mitigation action based on detecting the IM interference condition. The UE may reduce an uplink transmit power so that IM interference on the downlink is reduced. Various base station IM mitigation actions are provided, such as suspending scheduling on a bearer, using a scheduling pattern that avoids concurrent transmission, reducing a maximum transmit power of an uplink grant of the UE, allocating resource blocks or bandwidth parts that do not overlap with an IM interference resource, changing a secondary cell group channel to a non-interfering channel, releasing a secondary cell group channel, deactivating a carrier, or changing a channel of the UE.

  • Publication number: 20210120551
    Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may transmit a grant delay request to a base station. The grant delay request may indicate a future time, at or thereafter a base station is requested to allocate resources to the UE. The base station may transmit the uplink grant to the UE allocating the resources to the UE based on the grant delay request, and the UE may transmit, to the base station, an uplink transmission including the uplink data based on the uplink grant. The UE may transmit the grant delay request as part of a scheduling request (SR), or as part of a buffer status report (BSR), or a combination of these.

  • Patent number: 10951347
    Abstract: Advertising wireless devices (e.g., user equipments (UEs)) within a distributed wireless network may indicate radio frequency and/or baseband capabilities (e.g., via transmitting capabilities messages). A responding UE may receive one or more capabilities messages, and identify radio frequency (RF) capabilities (e.g., indicated via a bitmap) and/or baseband capabilities of the advertising UEs. The responding UE may then determine a transmission scheduling policy based on the one or more received capabilities messages. For example, the responding UE may generate a combined list of frequencies based on the one or more received capabilities messages, and distribute transmissions over the list of frequencies. Additionally or alternatively, the responding UE may determine block decoding baseband capabilities of the one or more advertising UEs, and may accordingly enable block coding schemes for transmissions on frequencies supported by the advertising UEs with such block decoding baseband capabilities.
