  • Patent number: 11917634
    Abstract: A base transmission signal and an auxiliary transmission signal may be used to (e.g., concurrently) improve a harvesting efficiency of an energy receiver while maintaining a prespecified performance level of an information receiver. An auxiliary transmission signal may be constructed. The construction of the auxiliary transmission signal may be signaled. An auxiliary transmission signal may be adapted. The adaptation of the auxiliary transmission signal may be signaled. An impact of auxiliary transmission signals on an information receiver's performance may be mitigated. One or more narrowband energy harvesting (EH) signals may be used, for example to provide a high peak to average power ratio (PARR) for EH devices (e.g., without significantly impacting overall transmitted signal PARR) characteristics. One or more narrowband auxiliary signals may be used, for example to enhance the PARR characteristics of an information signal sub-band.

  • Publication number: 20240064793
    Abstract: Aspects are provided which allow a UE to achieve sidelink parameter coordination through various signaling in clustered FL or peer-to-peer FL. The UE provides a first ML model information update and a measurement associated with the update. The UE obtains an aggregated ML model information update aggregating the first update with a second ML model information update of either a first network node in a FL cluster including the UE or a second network node in a second FL cluster. The UE provides a sidelink communication parameter in SCI to a network node, which parameter is an output of an ML model associated with the aggregated ML model information update. As a result, UEs may derive common SCI parameters from their updated ML models to apply in sidelink communications, thereby leading to maximized packet reception rate, maximized throughput, or minimized latency in communication.

  • Patent number: 11902865
    Abstract: Methods, systems, and devices for wireless communications are described. A first user equipment (UE), e.g., such as a pedestrian UE (PUE), may detect, during a first transmission period of a discontinuous transmission cycle, a transmission over a sidelink channel from a second UE that is located within a threshold distance from the first UE, the first UE associated with a first identifier. The first UE may determine, based at least in part on the transmission, a second identifier associated with the second UE, the second identifier being different from the first identifier. The first UE may use, based at least in part on the second UE being within the threshold distance, the first identifier and the second identifier during one or more subsequent transmission periods of the discontinuous transmission cycle.

  • Publication number: 20240048283
    Abstract: Methods and apparatuses are described herein for providing Hybrid Automatic Repeat Request (HARQ) techniques for a non-terrestrial network. For example, a wireless transmit/receive unit (WTRU) may transmit, to a satellite base station (BS), uplink (UL) feedback that includes configuration information for redundancy versions (RVs) and cross redundancy versions (cRVs). The WTRU may receive one or more first RVs associated with a first transport block (TB). The WTRU may receive one or more second RVs associated with a second TB and at least one cross redundancy version (cRV) associated with the first TB and second TB. The cRV may include parity bits generated from both the first TB and second TB. If at least one of the first TB or the second TB is unsuccessfully decoded, the WTRU may decode the first TB and second TB jointly based on the at least one cRV.

  • Patent number: 11895623
    Abstract: In one aspect, resource selection may be performed where single frequency full-duplex (SFFD) UEs are present in a V2X system. Signaling and procedures may enable the coexistence of half-duplex (HD) and SFFD-capable UEs. Based on the resource reservation information obtained from other UEs, the SFFD UE may determine which among the reserved time-frequency resources is amenable for performing the SFFD operation. In one aspect, the time-frequency resources chosen for SFFD may partially or fully overlap with the reserved time-frequency resources, based on the self-interference cancellation capability of the SFFD UE, the RSRP, and/or the RSSI on the reserved time-frequency resources. Accordingly, the full-duplex capability of an SFFD-capable UE may be leveraged, and spectral efficiency improved.

  • Publication number: 20240040415
    Abstract: Methods, systems, and devices for wireless communications are described. The described techniques provide for using situational information to aid in beam-based communications between a first user equipment (UE) and a network entity. The first UE may collect data at one or more sensors and may generate the situational information using the collected data. The first UE may then use the situational information in a beam selection procedure to identify suitable candidate beams for communicating with the network entity. The first UE may also transmit the situational information to the network entity in a beam management report, and the network entity may use the situational information to identify suitable candidate beams for communicating with the first UE. In some cases, the network entity may also use the situational information to identify suitable candidate beams for communicating with a second UE associated with the first UE.

  • Patent number: 11889541
    Abstract: Aspects relate to mechanisms for a wireless communication device to generate a superposition transmission of a sidelink signal to be transmitted to at least one receiving wireless communication device and an uplink signal to be transmitted to a base station. The wireless communication device may transmit the superposition transmission on resources allocated by the base station on a common carrier utilized for both sidelink and uplink transmissions. The superposition transmission includes a base layer corresponding to the uplink signal and an enhanced layer corresponding to the sidelink signal. The wireless communication device may further generate and transmit interference assistance information to the receiving wireless communication device for use by the receiving wireless communication device in canceling the base layer from the superposition transmission.

    Abstract: Methods, systems, and devices for wireless communications are described. Generally, the described techniques provide for a user equipment (UE) to measure self-interference between multiple transmission reception points (TRPs) of the UE and initiate sidelink full duplex communications based on the measured self-interference. The UE may transmit a message to a base station to request resources for sidelink communications by the UE and indicate an intended self-interference measurement by the UE using the resources. The base station may transmit a grant scheduling the resources for the self-interference measurement by the UE. The UE may measure interference between a TRP of the UE that is configured for transmission and a TRP of the UE that is configured for reception using the scheduled resources. The UE may transmit a sidelink feedback message indicating resources that are available for sidelink full duplex communications by the UE based on the measured self-interference.
