Abstract: Methods, systems, and devices for wireless communications are described. A wireless device, such as a user equipment and/or a base station, may determine that an active transmit beam has changed from a first transmit beam to a second transmit beam, the second transmit beam being different from the first transmit beam. The wireless device may identify a reference signal identifier that is associated with the second transmit beam. The wireless device may update, based at least in part on the identifying, a channel state information (CSI) resource setting to include the reference signal identifier, wherein the CSI resource setting is associated with the active transmit beam.

Abstract: Methods, systems, and devices for wireless communications are described. In some wireless communications systems, a wireless device may broadcast a discovery preamble to identify a receiving device or to identify a suitable beam for communicating with a receiving device prior to broadcasting a discovery message to the receiving device. In such systems, the wireless device may use the techniques described herein to generate the discovery preamble and to reduce interference between discovery preamble transmissions and avoid data loss. In one example, a wireless device may append a cyclic prefix (CP) to a discovery preamble with a suitable length to protect the discovery preamble from interference from another transmission. In another example, the wireless device may generate a cyclically periodic signal including multiple copies of the discovery preamble so a receiving device may be able to receive a portion of the signal and identify the discovery preamble.

Abstract: In order to improve cell detection in NR, a user equipment apparatus performs a PSS search on a first frequency raster from a group of frequency rasters. When the UE detects a PSS on the first frequency raster corresponding to a PSS hypothesis, the UE searches for an SS on a second frequency raster based at least on part on the detected PSS hypothesis on the first frequency raster. The UE may search for a plurality of hypotheses of the SS corresponding to the detected PSS hypothesis on the first frequency raster and the second frequency raster. The second frequency raster may be selected from the group of frequency rasters based at least in part on the detected PSS hypothesis or the first frequency raster on which the PSS was detected.

Abstract: Methods, systems, and devices for wireless communications are described. Generally, the described techniques provide for adjusting timing advance command parameters for specific beam pair links (BPLs) in a wireless communications system. In some cases, a base station may determine that transmission timing at a UE may be misaligned. The may send a timing advance (TA) command for the BPL. A UE may utilize more than one BPL, and may switch communications from a first BPL to second BPL. The second BPL may have a different timing misalignment than the first BPL, and the TA command sent by the base station may be insufficient to correct the timing misalignment of the second BPL. The base station may adjust the TA command parameters (e.g., TA command size or TA command granularity) so that the timing misalignment of the second BPL may be corrected.

Abstract: A network node of a communication network may determine that a target transmission power for a subsequent transmission by the network node is no longer optimal. In response to the determination, the network node may autonomously modify one or more parameters of the subsequent transmission, from a modulation and coding scheme (MCS) and/or a set resources for the subsequent transmission. The network node may then transmit a channel, based at least in part on the one or more modified parameters, to a target network node in the subsequent transmission. The target network node may determine that the network node has autonomously modified the one or more parameters of the transmission, from the modulation and coding scheme (MCS) and/or the set resources for the transmission. The target network node may process the transmission based on the determination.

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 communications are described. A wireless device may identify a set of power configurations for a plurality of communications with at least one target device. The set of power configurations may be based at least in part on a type of signal, a type of channel, a parameter of the wireless device, a parameter of the target device, or a combination thereof. The wireless device may then determine a duplexing mode for the plurality of communications based at least in part on the set of power configurations. The duplexing mode may be, for example, a full duplex mode or a half-duplex mode. The wireless device may then transmit the plurality of communications to and/or receive the plurality of communications from the at least one target device according to the set of power configurations and the selected duplexing mode.

Abstract: High frequency wireless communication networks rely on directional transmit and receive beams to achieve large gains and overcome large pathlosses associated with high frequency signals. With highly directional signals, link failure may occur. Network nodes associated with the link failure, may need to identify new beam pairs and establish a new link as quickly as possible. In several aspects, beam sweep procedures are expedited, allowing for rapid link reestablishment. Disclosed techniques allow for rapid link reestablishment with and without beam correspondence.

Abstract: Methods, systems, and devices for wireless communications are described. A central access node (CAN) may manage and schedule resources for a wireless mesh network. The CAN may transmit a first message to a relay access node (AN) to expedite transmission of a priority communication in the wireless mesh network. The first message may provide configuration information for modifying a preconfigured schedule to expedite the transmission of the priority communication. For example, the first message may provide configuration information to modify a preconfigured schedule to allow a first network node to transmit the priority communication to a second network node during a reserved time period. The relay AN may generate a second message regarding the modified schedule and transmit the second message to the second network node.
