Abstract: Wireless communications systems and methods related to communicating in an integrated access backhaul (IAB) network are provided. A first wireless communication device transmits to a second wireless device during a first one of a plurality of slots; and receives a second transmission from the second wireless device during a second one of the plurality of slots. The second transmission includes link quality information about the first transmission and scheduling information for a third transmission between the first and second wireless devices.

Abstract: Methods, systems, and devices for wireless communications are described that support resource utilization based event triggering. A wireless node in a wireless communications system may establish a connection with a core network via a path that includes one or more relay nodes. The wireless node may determine that a network load associated with one or more paths between the wireless node and the core network has changed, or that a difference between two or more network loads of different paths has changed. Based on such a determination, the wireless node may transmit a report to the network. In some cases, the network may receive the report from the wireless node, and may initiate a path change based on the report.

Abstract: A user equipment (UE) can transmit a beam failure recovery request using contention-based physical random access channel (PRACH) resources to supplement and/or replace non-contention-based resources for transmitting the beam failure recovery request. The UE can reduce beam recovery latency by informing its intention for beam failure recovery by transmitting a beam failure recovery request during the random access channel (RACH) procedure. The base station may dedicate a set of RACH resources that can be used for both transmitting regular contention-based RACH messages and beam failure recovery request.

Abstract: Backhaul resources may be allocated to different wireless communication links between different base stations, and local redistribution of resources among base stations may be utilized to account for variations in signal quality and/or variations in traffic experienced by different nodes of the backhaul network. A first access node function (ANF) may determine a need for additional backhaul resources, and may transmit a request message to one or more user equipment functions (UEFs) for additional backhaul resources. A UEF that receives the request message may forward the request to an associated second ANF. The second ANF, if it has backhaul resources available that the first ANF can use, may send a response to the first ANF, via the associated UEF, and the first ANF may use the additional resources that were originally allocated to the second ANF.

Abstract: A user equipment (UE) may communicate with a base station through a first active beam, the first active beam comprising a serving beam. The UE may receive a first reference signal and a second reference signal associated with beam tracking from the base station, where the first reference signal is received through a first beam of a first plurality of beams and the second reference signal is subsequently received through a second beam of a second plurality of beams, and where the beam tracking includes identifying a new beam for communication between the UE and the base station. The UE may communicate with the base station through a second active beam based on at least one of the first reference signal or the second reference signal associated with the beam tracking, the second active beam comprising the new beam.

Abstract: Methods, systems, and devices for wireless communications are described that provide for selection of different sets of transmission beams by a user equipment (UE) for establishing beamformed communications with a base station. Each transmission beam of a first set of transmission beams may have corresponding uplink random access channel (RACH) resources. A UE may monitor for transmission beams from a base station and select a first transmission beam of the first set for communications with the base station. As part of a connection establishment, the base station may provide configuration information that indicates a second set of transmission beams that includes each transmission beam of the first set of transmission beams and at least an additional transmission beam. In some cases, the additional transmission beam may be mapped to a first RACH resource that also corresponds to a first transmission beam of the first set of transmission beams.

Abstract: Methods, systems, and devices for wireless communication are described. A base station may use quasi co-located antenna ports for transmission of synchronization signal(s)/reference signal(s) and paging signals. For example, the base station may use a first antenna port configuration for transmission of the synchronization/reference signal(s) and a second antenna port configuration for transmission of the paging signal (e.g., paging indicator, paging message, etc.). The base station may transmit an indication of the quasi co-located antenna ports. A user equipment (UE) may receive the synchronization signal and, based on the antenna ports being quasi co-located, receive the paging signal. In some examples, the UE may determine which receive beam to use to receive the paging signal based on the antenna ports being quasi co-located. In some aspects, the UE may use a reference signal transmitted on antenna ports that are quasi co-located with the paging signal antenna ports.

Abstract: Aspects of the present disclosure provide for random access channel (RACH) configuration in wireless communication systems. In some examples, a RACH configuration may be selected for use by a scheduled entity in transmitting a RACH signal to a scheduling entity based on an estimated timing advance value. The RACH configuration may include, for example, a transmission time of the RACH signal and/or a RACH waveform configuration identifying at least a cyclic prefix (CP) length and a guard time (GT) for the RACH signal. In some examples, the CP and GT length may each be set to the difference between an estimated maximum round-trip time (RTT) and an estimated minimum RTT between the scheduled entity and the scheduling entity. In some examples, the timing advance value may be estimated as the estimated minimum RTT.

Abstract: Methods, systems, and devices for wireless communication are described in relation to a Multiple Subscriber Identify Module (MSIM) user equipment (UE). The UE associated with multiple network subscriptions may determine a first timing of a first set of paging occasions associated with a first network subscription of the multiple network subscriptions, wherein the first network subscription is associated with a first network; determine a second timing of a second set of paging occasions associated with a second network subscription of the multiple network subscriptions, wherein the second network subscription is associated with a second network; compare the first timing and the second timing; detect a paging time adjustment condition based on the comparing; and based on the detecting, transmit to the first network, the second network or both a random access signal using a random access resource configured to convey a paging time adjustment request.
