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.

Abstract: Methods, systems, and devices for wireless communications are described for initiating beam training in systems that use beamformed wireless communications. A user equipment (UE) and a base station may establish communications using a first beam, and the UE may determine that a signal quality of the first beam is lower than a threshold value and that a beam training procedure is to be initiated. The UE may transmit a beam training request to initiate the beam training procedure, which may be transmitted as part of a bit sequence that is used to transmit uplink control information to the base station, such as with acknowledgment/negative-acknowledgment feedback, a scheduling request, or other uplink control information.

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. Otherwise, the first wireless device may retransmit a control message if the first control message was not successfully received.

Abstract: Methods, systems, and devices for wireless communications are described. A first base station may receive, from a plurality of user equipments (UEs), a plurality of uplink signals that include feedback information for the plurality of UEs. A first UE of the plurality of UEs may be associated with the first base station and a second UE of the plurality of UEs may be associated with a second base station. The first base station may modify a plurality of sets of beam weights for a plurality of downlink signals, where each modified set of beam weights corresponds to a respective downlink signal of the plurality of downlink signals. The first base station may transmit, to the first UE, a first downlink signal of the plurality of downlink signals using a first modified set of beam weights of the of the plurality of sets of beam weights.

Abstract: Methods, systems, and devices for wireless communications are described that provide a repeater for beamforming a received signal at a millimeter wave (mmW) radio frequency via one or more scan angles or beamforming directions and then retransmitting and beamforming the signal at the mmW radio frequency. Repeaters may include analog and digital components for downconverting on the received signal to reduce a frequency of the signal from the mmW frequency to an intermediate frequency (IF) or baseband frequency, and then filtering the downconverted signal to reduce interference. The filtering may include digital filtering or a combination of analog and digital filtering, in which a set of filter coefficients for the digital filtering is selected based on beamforming parameters used to receive the signal, retransmit the signal, or both. The repeater may then upconvert the filtered signal back to the mmW frequency for the retransmission of the signal.

Abstract: The position of a mobile device is estimated using angle based positioning measurements. The angle based positioning measurements are generated using transmit (Tx) beams or receive (Rx) beams from one or more base stations that generate the beams over an ultra-wide bandwidth, which produces frequency and spatial distortions and impairments in an array gain response. The array gain distribution variation as a function of angle and frequency for the set of beam weights used in beamforming is conveyed to indicate the frequency and spatial distortions. The array gain distribution variation may be provided to the mobile device in assistance data for a sub-band that is only a portion of the allocated bandwidth for the base stations, or as an aggregation of the array gain distribution variation for a plurality of sub-bands of the allocated bandwidth to reduce the overhead in signaling.

Abstract: Certain aspects of the present disclosure relate to methods and apparatus for limiting UE capability information reported in a network. For example, a method of wireless communications by a first base station may include transmitting a first set of initial access signals in different directions, receiving a second set of one or more signals from a user equipment (UE) in response to the first set of initial access signals, and initiating transmission of, or conveying configuration of, a third set of reference signals with an indication of their corresponding directions, based on reception of the second set of signals.

Abstract: In an aspect of the disclosure, a method, a computer-readable medium, and an apparatus are provided. The apparatus may transmit a first physical random access channel (PRACH) transmission that includes a first random access (RA) preamble to a base station. The apparatus may determine whether to transmit to the base station a second PRACH transmission that is concurrent with the first PRACH transmission in time, wherein the second PRACH includes a second RA preamble. The apparatus may transmit, to the base station, the second PRACH transmission that includes the second RA preamble when the second PRACH transmission is determined to be transmitted. The first RA preamble and the second RA preamble may be different, and the first RA preamble and the second RA preamble may be concurrently transmitted in a same PRACH occasion or in different PRACH occasions that overlap in time.

Abstract: An apparatus are provided for wireless communication at a base station with improved PBCH construction and decoding. The base station apparatus constructs a PBCH payload, wherein a bit location is selected for encoding a plurality of bits of the PBCH based on an estimated reliability for the corresponding bits location wherein the plurality of bits comprises frozen bits, unknown bits that are unknown to a user equipment, and potentially known bits that are potentially known by the user equipment. The apparatus transmits the PBCH payload in at least one of a plurality of SS blocks. A UE receiving the PBCH decodes the PBCH based on a successive decoding order. The successive decoding order may be based on an estimated reliability for the corresponding bits, e.g., in which potentially known bits are decoded prior to unknown bits.
