  • Patent number: 11546046
    Abstract: Systems, apparatuses, and methods for enhancement for amplify-and-forward relay. Instead of merely passing received signal from a source, relay may equalize the received signal based on reference signal contained in the received signal, before amplifying and transmitting the signal to a destination. Compared to amplify-and-forward, equalize-and-forward may compensate the received source signal for various imperfections such as channel distortions and phase errors, using demodulation reference signal and phase tracking reference signal. The relay may apply Fast Fourier Transform (FFT) to equalize the signal in tone domain.

  • Patent number: 11533750
    Abstract: Methods, systems, and devices for wireless communications are described that provide for transmission of random access preambles from a UE based at least in part on a synchronization signal block (SSB) that is received from a base station. A random access response may be transmitted from the base station based at least in part on a random access resource that is used for the random access preamble, an SSB associated with the random access resource, an SSB index, or combinations thereof. In some cases, two or more SSBs may be mapped to a single random access resource, and a single random access radio network temporary identifier (RA-RNTI), or two or more RA-RNTIs, may be used for each of the two or more SSBs. In some cases, a single random access response message contains information for each UE that transmits a random access preamble in the single random access resource.

  • Publication number: 20220394561
    Abstract: Methods, systems, and devices for wireless communications are described. The described techniques may enable a first wireless device (e.g., a parent node) to transmit a control message to a second wireless device (e.g., a child node). The control message may include a resource reservation for communication with the second wireless device. The second wireless device may receive the control message and may transmit an acknowledgment message acknowledging successful reception of the resource reservation. The first wireless device may monitor for the acknowledgment message and may communicate with the second wireless device based on whether the acknowledgment message is received. For example, if the first wireless device receives feedback acknowledging successful reception of the resource reservation at the second wireless device, the devices may communicate data in the reserved resources.

  • Patent number: 11510090
    Abstract: Disclosed are techniques for using a channel state information (CSI) report framework to support positioning measurements in a wireless network. More particularly, a base station may identify one or more reference signal resources to be transmitted to a user equipment (UE) for obtaining at least one positioning measurement and configure the reference signal resources to be transmitted at least partially outside a current bandwidth that the base station and the UE are using to communicate data and control information. Accordingly, the base station may transmit, to the UE, a CSI report setting that indicates the positioning measurement to be reported and specifies that the positioning measurement is to be obtained from the configured reference signal resources.

  • Patent number: 11510071
    Abstract: Methods, systems, and devices for wireless communications are described. The described techniques enable a first wireless device (e.g., an integrated access and backhaul (IAB) node in an IAB system) or a network entity (e.g., a centralized unit (CU) in the IAB system) to select a set of wireless devices for communication. The first wireless device, the CU, or both may select the set of wireless devices for communication based on a pathloss mode of the first wireless device, whether an angular separation between a group of nodes (e.g., one or more of the set of wireless devices) is less than an angular separation threshold, or both. The first wireless device may communicate with the set of wireless devices with one or more communications beams. For example, the device may communicate with multiple wireless devices using a single communication beam if the angular separation between the multiple devices is relatively low.

  • Patent number: 11477747
    Abstract: Methods, systems, and devices for wireless communications are described. Different periodicities may be dynamically selected when monitoring and transmitting signaling used for link management, where respective periodicities may be based on the quality of the link between devices. For instance, a first wireless device may use a first monitoring periodicity to monitor for signals transmitted from another wireless device. Upon determining that a link condition has changed (e.g., decreased or reached a threshold), the first wireless device may decrease its monitoring periodicity (and increase monitoring frequency) to detect signals transmitted by the other wireless device more frequently. In such cases, the other wireless device may likewise transmit its measurement signals more often (e.g., in accordance with a second periodicity) based on the link quality. The adjusted monitoring and transmission periodicities may provide additional occasions for the wireless device to detect signals from another device.
