Abstract: Methods, systems, and devices for wireless communications are described. In some examples, a base station may identify one or more communication paths to a user equipment (UE), and may determine an end-to-end signal quality for each communication path (e.g., a signal-to-noise ratio (SNR)), one or more hop SNR values for each hop of each communication path, a ratio of the hop SNR values and the end-to-end SNR of each communication path, or a combination thereof. Based on the determined SNR values, ratios, or both, the base station may select a first communication path for a first type of communications (e.g., uplink, downlink, signal type, or the like) and a second communication path for a second type of communications (e.g., uplink, downlink, signal type, or the like), and may communicate with the UE using the selected communication paths.

Abstract: Aspects of the present disclosure provide apparatus, methods, processing systems, and computer readable mediums to enhance the functionality of directional repeaters (wireless devices that relay directional wireless signals). For example, aspects of the present disclosure may help enable repeaters to provide greater assistance in an access procedure, for example, by generating and sending SSBs without (or with limited) gNB involvement and monitoring for RACH-related transmissions.

Abstract: Methods, systems, and devices for wireless communications are described. A wireless device, such as a base station and/or a user equipment (UE), may select a first resolution for a first analog-to-digital or digital-to-analog conversion process associated with a first wireless communication. The wireless device may determine that the first wireless communication is performed according to the first resolution. The wireless device may select, based at least in part on the determining, a second resolution for a second analog-to-digital or digital-to-analog conversion process associated with a second wireless communication, the first resolution being a lower resolution than the second resolution.

Abstract: When a first node is subject to a maximum permissible exposure (MPE) condition, it may be beneficial for the first node to signal, to a second node, an uplink beam to be used for communications and/or one or more properties of the uplink beam. For example, the first node may signal a downlink beam, from a first reciprocal beam pair, and an uplink beam, from a second reciprocal beam pair, to be used for communications, and/or may signal one or more properties of the uplink beam and/or the downlink beam. Additionally, or alternatively, the second node may transmit, to the first node, a signaling state (e.g., a transmission configuration indication (TCI) state) that indicates properties to be used to configure an uplink beam and/or a downlink beam. In this way, the first node and the second node may configure beams in a manner that accounts for MPE limitations.

Abstract: Methods, systems, and devices for wireless communication are described. A base station may transmit, to a user equipment (UE) operating in a discontinuous reception mode, a wakeup signal indicating whether data is available to be transmitted to the UE, the wakeup signal transmitted using a first set of transmit beams, which may be selected from a periodic beam management procedure, in accordance with a beam sweeping configuration. The base station may receive, from the UE and based at least in part on the wakeup signal, a response signal. The base station may perform, based at least in part on the response signal, further beam update procedures to identify a second set of transmit beams for future transmissions of the wakeup signal and/or for transmission of physical downlink control channel (PDCCH) to the UE.

Abstract: Methods, systems, and devices for wireless communication are described. A base station may initiate a beam management procedure, including reference signal transmission to a user equipment (UE) and receive beam training. A base station may configure a UE to monitor a set of beams for reference signals. Based on the received reference signals, the UE may optionally select one or more transmit beams for wakeup signal reception, and may transmit an indication of the selected beams to the base station. The base station may transmit a wakeup signal over the originally configured or the UE-selected transmit beams to initiate wake-up procedure at the UE. The base station and UE may subsequently perform a refined beam management procedure, providing a refined reference signal transmission from the base station. Based on the received transmission, the UE may select a refined beam for downlink transmissions.

Abstract: Methods, systems, and devices for wireless communication are described. A base station may identify that data is available to be transmitted to a user equipment (UE) that is operating in a discontinuous reception mode. The base station may transmit, based at least in part on identifying that the data is available to be transmitted to the UE, a wakeup message to the UE using a first transmit beam. The base station may initiate a beam management procedure based at least in part on identifying that the data is available to be transmitted to the UE, to identify a second transmit beam for the base station to use to transmit the available data to the UE, wherein the second transmit beam comprises a narrower beam width than the first transmit beam.

Abstract: A UE may receive an indication of a beam pair link (BPL), wherein the BPL comprises a base station (BS) transmit beam and a corresponding UE receive beam. The UE may tag the BPL based on the UE receive beam. The UE may take one or more actions associated with the tagged BPL.

Abstract: Methods, systems, and devices for wireless communication are described.. In aspects of the present disclosure, a user equipment (UE) may report metrics (e.g., received signal power, beam identifier) about synchronization signal (SS) beams using the same (e.g., or a similar) framework that is used for channel state information reference signal (CSI-RS) reporting. Because SSs are intended to be broadcast across a wide coverage area in a beamformed manner, the SSs represent a promising complement to existing beam management techniques. Accordingly, beam management may be achieved at least in part based on reporting one or more metrics of beamformed SSs through a channel feedback framework.

Abstract: Methods, systems, and devices for wireless communication are described in which a number of reference signal processes may be configured for a number of slots in a radio frame, and a corresponding reference signal process for each slot may be based at least in part on a location of the slot within the radio frame and a number of configured reference signal processes. An indication may be provided to a user equipment (UE) in each slot that indicates a presence or absence of a reference signal transmission in the slot.
