  • Publication number: 20230217418
    Abstract: Disclosed are techniques for wireless communication. In an aspect, a position estimation entity (e.g., UE, gNB, LMF, etc.) identifies a pool of UEs for a SL-assisted position estimation procedure of a set of target UEs. SL SRS-Ps are communicated (e.g., transmitted and measured) between the pool of UEs (e.g., for relative SL ranging). UL SRS-Ps are communicated by at least some of the UEs in the pool of UEs. The position estimation entity obtains measurement data for both the SL SRS-P and UL-SRS-P communications. The position estimation entity determines a position estimate for each UE in the set of UEs based on the measurement information.

  • Publication number: 20230217441
    Abstract: Aspects are provided which allow a base station to indicate use of a mini-slot based resource allocation in sidelink communications between a Tx UE and a Rx UE. Initially, the base station configures control information indicating a sidelink data resource for a mini-slot, and transmits the control information to a Tx UE. After the Tx UE receives the control information, the Tx UE transmits sidelink data in the sidelink data resource to a Rx UE. Similarly, the Rx UE receives the control information from either the Tx UE or the base station, and the Rx UE receives the sidelink data in the sidelink data resource from the Tx UE. Accordingly, the base station may schedule the Tx UE and Rx UE to communicate sidelink data in mini-slots rather than slots, thereby reducing scheduling latency, increasing the number of available resources, and achieving more flexibility in sidelink communications.

  • Patent number: 11696318
    Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first wireless communication device may receive, from a second wireless communication device, an announcement associated with a first future communication and that indicates a set of resources associated with the first future communication. The first wireless communication device may communicate using the set of resources based at least in part on a determination that an estimated interference that will result from a second future communication using the set of resources satisfies an interference condition. Numerous other aspects are described.

  • Patent number: 11696210
    Abstract: Systems and methods configured for supporting multi-hop communications are described. Embodiments provide unavailable packet signaling by a base station aiding a multi-hop communication link. For example, the base station may transmit a predetermined “unavailable” message (e.g., an explicit and affirmatively transmitted message having predetermined content and/or format transmitted according to the schedule of the failed message) when an uplink data transmission in a multi-hop communication link fails or is otherwise currently unavailable. The unavailable packet signaling may be provided in association with a semi-persistent scheduling (SPS) and control channel scheduled retransmission technique, such as for supporting Internet of things (IoT), such as industrial Internet of things (IIoT), traffic. Other aspects and features are also claimed and described.

  • Publication number: 20230209545
    Abstract: Methods, systems, and devices for sidelink configured grant skipping are described. In some examples, a first user equipment (UE) may receive, from a base station, an indication of periodic data resources for a plurality of sidelink data transmissions and an indication of negative scheduling request resources for the first UE to report a skipped sidelink data transmission associated with the plurality of sidelink data transmissions. In some examples, the first UE may transmit, to a second UE, an indication of the skipped sidelink data transmission and may transmit, to a base station, a negative scheduling request using the negative scheduling request resources, where the negative scheduling request may report the skipped data transmissions associated with the plurality of sidelink data transmissions.

  • Publication number: 20230198700
    Abstract: Method and apparatus for switching between SS-TWR and DS-TWR. The apparatus reserves resources for transmission of a first SL-PRS in a first time slot. The apparatus transmits, to a second UE, the first SL-PRS within the first time slot. The apparatus receives, from the second UE, a second SL-PRS at a second time based on the first time slot and a response time associated with transmission of the second SL-PRS in response to the first SL-PRS. The apparatus measures a time difference between the transmission of the first SL-PRS and reception of the second SL-PRS to determine if a third SL-PRS is to be transmitted to the second UE.

  • Publication number: 20230189269
    Abstract: Systems, methods, and devices for wireless communication that support mechanisms for configuring an uplink relay for wireless powered IoT operations in a wireless communication system. A base station transmits a power signal to wireless powered IoT devices. The wireless powered IoT devices harvest energy from the power signal to power their reception/transmission circuitry. The base station transmits an information signal to trigger the wireless powered IoT devices to reflect a backscatter transmission. The wireless powered IoT devices transmit a backscatter transmission in response to receiving the information signal from the base station. The base station transmits configurations to a UE including configuration information respectively corresponding to the wireless powered IoT devices, and include information that the UE may use to detect the backscatter transmissions from the wireless powered IoT devices and relay them to the base station based on the configurations.

  • Publication number: 20230189277
    Abstract: Methods, systems, and devices for wireless communication are described. A base station may transmit a grant to a first user equipment (UE) that indicates a resource allocation for a sidelink communication, either from the first UE to a second UE or from the second UE to the first UE. The grant may include a destination identifier associated with the sidelink communication, as well as a mapping between the resource allocation and the destination identifier. The destination identifier may be based on information in an indication received from the first UE. In some examples, the base station may configure a default receiver UE for transmissions from the first UE, and the base station may identify a receiver UE in the grant if the intended receiver UE is different than the default receiver UE.

  • Patent number: 11678325
    Abstract: Methods, systems, and devices for wireless communications are described to support resource selection for a sidelink transmission based on a priority of available resources. A physical (PHY) layer of a user equipment (UE) may report different subsets of available resources to a medium access control (MAC) layer. Each subset may be associated with a different priority and the MAC layer may use the subsets to select a resource for the sidelink transmission. The MAC layer may additionally or alternatively maintain a list of UE identifiers (IDs) and may provide the list of the UE IDs to the PHY layer for resource identification. The PHY layer may use the list to implement different reference signal parameters for UEs associated with the list of UE IDs than for other UEs. The PHY layer may report the set of available resources to the MAC layer, based on the list of UE IDs.

  • Patent number: 11672002
    Abstract: Base stations of neighbor cells can coordinate with each other in allocating grant-free uplink (GUL) resources for a device-to-device (D2D) connection or channel between user equipments (UEs) across the neighbor cells. The base stations coordinate to determine a condition conducive to D2D communication between the UEs. If the condition exists, the base stations coordinate to allocate network resources for D2D communication between the UEs, and establish a D2D connection between the UEs using the allocated network resources for D2D communication.
