  • Patent number: 11722992
    Abstract: Certain aspects of the present disclosure provide a user equipment (UE) that may receive an indication of a proximity discovery resource in a physical sidelink feedback channel (PSFCH) symbol from a network entity. The UE may transmit a proximity discovery request including the indication of the proximity discovery resource. The UE may receive a PSFCH sequence associated with the proximity discovery resource from other UEs that may respond to the proximity discovery request. The UE may transmit a bit map sequence indicative of the other UEs to the network entity. The network entity may determine a proximity between the UE and the other UEs based on the bit map sequence. The network entity may schedule the UE and the other UEs based on the proximity.

  • Patent number: 11722287
    Abstract: Methods, systems, and devices for wireless communication are described. A wireless device may identify multiple regions within a subframe, such as one or more uplink regions, one or more downlink regions, and a guard region. The wireless device may identify and communicate during each region based on a timing relationship between the downlink region and the uplink region. For example, the device may expect hybrid automated repeat request (HARQ) feedback for one downlink region in the same subframe based on the proximity to the next uplink region. Another downlink region may not have HARQ feedback in the same subframe. Similarly, uplink regions may or may not be scheduled within the same subframe.

  • Patent number: 11723039
    Abstract: Aspects presented herein may enable a base station to configure constraints on one or more transmission directions of a UE to reduce interference between UEs. In one aspect, a UE receives, from a base station, a grant for time-frequency resources for transmitting to a second UE, the grant including information indicating at least one of a first subset of beams of a set of beams for which the grant applies or a second subset of beams of the set of beams for which the grant applies with a constrained transmission power. The UE transmits, to the second UE, a PSSCH through at least one beam of the first subset of beams based on the received grant, or through at least one beam of the second subset of beams with the constrained transmission power based on the received grant.

  • Publication number: 20230246760
    Abstract: Providing downlink and uplink processing is disclosed for a cooperative user equipment (UE) operations. A UE participating in the cooperative UE may determine a processing capability associated with each cooperative operational mode of one or more cooperative operation modes of which the UE is capable. The UE sends a cooperative capability report to a serving base station that includes identification of the one or more capable cooperative operation modes and the processing capability of the UE associated with the each cooperative operation mode. The base station may then configure the UEs based on this capability information. The UEs would receive a cooperative mode configuration message from the serving base station with the configuration of a cooperative operation mode for the UE. The UE may then conduct cooperative UE communications using the configured mode according to its associated processing capability. Other aspects and features are also claimed and described.

  • Publication number: 20230246756
    Abstract: Downlink schemes are disclosed for a cooperative user equipment (UE) with joint baseband processing. UEs may establish a cooperative UE unit with one or more neighboring UEs, where one of the UEs operates as the primary UE. The participating UEs of the cooperative UE unit determine a downlink transmission scheme for the cooperative transmissions from a serving base station and receive cooperative transmissions of one or more transport blocks from the serving base station according to the downlink transmission scheme. The secondary UEs of the cooperative UE unit generate and transmit cooperative process data to the primary UE, where the cooperative process data is based on the receipt of the cooperative transmissions by the secondary UEs. The primary UE processes its received cooperative transmission along with the cooperative process data to decode the one or more transport blocks. Other aspects and features are also claimed and described.

  • Patent number: 11716755
    Abstract: Aspects are provided that allow a base station to provide a user equipment (UE) multiple timing opportunities to transmit an acknowledgment to a pre-grant (APG) after receiving a pre-grant for a downlink transmission. The base station transmits to the UE a pre-grant for a downlink transmission from the base station, the pre-grant triggering a plurality of timing opportunities for the UE to send an APG to the base station. The UE performs, after receiving the pre-grant, a clear channel assessment (CCA) during at least one timing opportunity of the plurality of timing opportunities. The UE transmits one or more APGs to the base station when the CCA is successful, and the UE receives the downlink transmission from the base station in response to the one or more APGs. The UE transmits the one or more APGs to the base station until the downlink transmission is received from the base station.

  • Publication number: 20230232407
    Abstract: This disclosure provides methods, devices, and systems for resource selection supporting the identification of resources for receiving two-stage downlink control information (DCI). In some systems, for example, a base station may transmit a first stage DCI and a second stage DCI to a user equipment. The first stage DCI may include control information for a group of UEs including the UE and the second stage DCI may include control information that is specific to the UE. The UE may determine a resource to use for receiving the second stage DCI based on an indication in the first stage DCI. In some examples, the UE may determine a resource from a resource pool based on a resource selector included in the first stage DCI and receive the second stage DCI over the determined resource. The resource pool may be indicated by the first stage DCI or pre-configured at the UE.

  • Patent number: 11706804
    Abstract: Technology-specific listen before talk (LBT) parameter adjustments are disclosed for common energy detection (ED) thresholds. Some of the technologies sharing access to the same shared communication spectrum include additional access deferral procedures. Such technologies may be configured with additional compensating features to increase the likelihood of fairness in spectrum access across all technologies sharing a common ED threshold. Such additional compensating features may include a reduced contention window size relative to the technologies that do not include such additional access deferral procedures, increased maximum channel occupancy times (COTs) for longer transmissions, and the like. Each such additional compensating feature may be available under different circumstances, such as always available or available in response to the node activating one of the additional access deferral procedures.
