Abstract: Methods, systems, and devices for wireless communication are described. Synchronization signals may be transmitted using a set of phase offsets over different component carriers or using a single component carrier for each antenna port. For example, a base station may identify a set of synchronization signals (e.g., a set of primary synchronization signals (PSSs)) to be transmitted over one or multiple component carriers. In some cases, each PSS may be associated with a different component carrier, and the base station may apply a different phase offset to each PSS when transmitting the set of PSSs on the component carriers. In some examples, the base station may transmit the PSSs on the component carriers using a different antenna port for each component carrier.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a control node may determine, for a target wireless node in communication with a plurality of other wireless nodes via a plurality of links of a network, a plurality of powers for the plurality of links, wherein the plurality of powers are selected to control inter-link interference or to satisfy a maximum power criterion. The control node may cause at least one of the target wireless node or the plurality of other wireless nodes to use the plurality of powers for concurrent transmissions to the target wireless node using the plurality of links based at least in part on determining the plurality of powers. Numerous other aspects are provided.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a wireless communication device may identify a scaling factor associated with determining a periodicity of backhaul physical random access channel (PRACH) resources. The wireless communication device may determine, based at least in part on the scaling factor, the periodicity of the backhaul PRACH resources. The periodicity of the backhaul PRACH resources may be extended as compared to a periodicity of access PRACH resources. Numerous other aspects are provided.

Abstract: Aspects of the present disclosure provide for beam management in wireless communication systems. In some examples, beam angle information (e.g., angles of arrival/departure) may be utilized to select one or more serving downlink beams for communication between a scheduling entity and a scheduled entity. The beam angle information may further be utilized to facilitate additional operations within a backhaul network, such as wireless node locating, obstacle locating, system mapping within the network topology, beam determination and beam sweeping configuration, and mobility management among wireless nodes of a backhaul network. In other examples, aperiodic uplink beam measurements may be triggered based on downlink beam measurement reports and/or in response to a request from a scheduled entity. The scheduling entity may then jointly select uplink and downlink beams based on both the received downlink beam measurement report and uplink beam measurements.

Abstract: Methods, systems, and devices for wireless communications are described. A wireless repeater may communicate with multiple base stations, and the wireless repeater may identify a first base station as a primary base station. The wireless repeater may monitor for and receive control information from the primary base station, where the control information may include control information from a second base station and used by the wireless repeater to communicate with one or more UEs connected to the second base station. The primary base station may receive an indication of the control information from the second base station via a backhaul link. In other examples, the wireless repeater may monitor for control information from the two or more base stations based on a control signaling pattern. For example, the wireless repeater may be configured with periodic time intervals for monitoring for control signaling from respective base stations.

Abstract: Methods, systems, and devices for wireless communications are described. A wireless repeater may monitor for transmissions from multiple base stations. For example, a wireless repeater may communicate with a first base station and forward transmissions from the first base station to various user equipment (UEs). Such transmissions may include transmitting synchronization signal blocks (SSBs) for the first base station. The first base station may instruct the wireless repeater to monitor for SSBs from other base stations, where the wireless repeater may indicate the monitoring results in a report to the first base station. Based on the report, the first base station may transmit an indication of a beam pattern to the wireless repeater. The wireless repeater may use the beam pattern for repeating transmissions of SSBs received from the first base station, SSBs received from the second base station, or any combination thereof.

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: Certain aspects of the present disclosure relate to methods and apparatus for multiplexing new radio (NR) synchronization signals and paging signals. A Base Station (BS) decides whether or not to multiplex paging and synchronization signals in a set of time resources, a set of frequency resources or a combination thereof, the deciding based on at least one of a capability of the BS, a capability of at least one User Equipment (UE) served by the BS, an operating frequency band or a combination of tone spacings of the paging signals and the synchronization signals.
