Abstract: Certain aspects of the present disclosure provide techniques for use of SS transmitted using a UE-specific configuration of time-frequency resources. A BS may assign at least one UE-specific configuration, wherein the UE-specific configuration comprises an allocation of resources for a UE-specific SS for mobility management purposes. The BS may communicate with the UE based, at least in part, on the UE-specific configuration. A UE may correspondingly receive the UE-specific configuration and communicate with a BS based, at least in part, on the configuration.

Abstract: Certain aspects of the present disclosure generally relate to wireless communication. In some aspects, a base station may determine a transmission configuration for a first random access message based at least in part on one or more parameters associated with a target base station for initiating a backhaul connection. The transmission configuration may include information associated with a physical random access channel (PRACH) resource associated with transmitting the first random access message. The PRACH resource differs from a PRACH resource associated with a transmission of a random access message by a user equipment. The base station may transmit the first random access message using the transmission configuration. Numerous other aspects are provided.

Abstract: Certain aspects of the disclosure provide techniques for random access channel (RACH) power control, including for message (MSGA) transmission by a user equipment (UE) for two-step RACH procedure. Certain aspects provide a method for wireless communication generally including determining a transmit power for transmitting a first message to a base station (BS) as part of a two-step RACH procedure, the first message comprising a first part and a second part. Determining the transmit power comprises determining a first transmit power for transmitting the first part based on a first function having parameters including a power ramping counter and a power ramping step. Determining the transmit power further comprises determining a second transmit power for transmitting the second part based on a second function having parameters including the power ramping counter and the power ramping step. The method further includes incrementing the power ramping counter based on transmitting the first message.

Abstract: Methods, systems, and devices for wireless communications are described that provide for system information (SI) for access and backhaul. An access node (AN) may provide SI to devices within its cell indicating communication procedure configurations. The AN may provide SI to devices that is specific to whether the communication procedure is an access procedure or a backhaul procedure. The AN may transmit a common master information block (MIB) directing the devices within its cell to a search space in order to receive the remaining SI. The search space may be shared between access devices and backhaul devices or alternatively may be separate between access and backhaul devices. The remaining SI may not be shared between access and backhaul devices. The devices may determine different configurations as defined by the SI from the AN for communications procedures based on whether the procedure is an access procedure or a backhaul procedure.

Abstract: In order to maintain conformance with exposure limits, in band measurements may be performed. A method, a computer-readable medium, and an apparatus may be provided for wireless communication at a user equipment. The apparatus receives an indication of a cell specific resource, e.g., a cell specific resource available for MPE measurement. The apparatus then performs a measurement based on the cell specific resource and determines whether to adjust a transmission characteristic of the user equipment based on whether the measurement meets a threshold. In another aspect a base station apparatus may configure a cell specific resource in which a user equipment may perform an MPE measurement and control use of the cell specific resource for the MPE measurement.

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: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a wireless node may receive association information for a set of soft resources of the wireless node. The association information may indicate one or more parent nodes associated with a soft resource of the set of soft resources. The set of soft resources may be configurable as schedulable or non-schedulable for the wireless node. The wireless node may determine one or more release indications associated with the soft resource. The wireless node may schedule on the soft resource based at least in part on determining the one or more release indications. Numerous other aspects are provided.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, an integrated access and backhaul (IAB) node may receive at least part of a resource pattern of a child IAB node associated with the IAB node. The resource pattern may indicate one or more configurations of one or more resources of the child IAB node. The IAB node may communicate with the child IAB node based on the at least part of the resource pattern. Numerous other aspects are provided.

Abstract: Aspects of the present disclosure provide methods, apparatuses, and embodiments for transmitting time critical uplink (UL) control information (e.g., beam failure indication, buffer status report, and scheduling request) without first obtaining UL timing synchronization with a network. Therefore, UL communication latency may be reduced by removing the signaling overhead involved in performing a full random access procedure to obtain UL synchronization prior to UL transmission.
