Abstract:
In an aspect, methods, apparatuses, and computer-readable mediums for wireless communications in an integrated access and backhaul (IAB) network are disclosed. In an example, the method includes determining a topological state of one or more of a parent node or a child node, determining a scheduling gap value for a set of resources, including a resource for the child node, based on the topological state of one or more of the parent node or the child node, and transmitting a configuration to the parent node for communicating with the child node based at least in part on the scheduling gap value.
Abstract:
Methods, systems, and devices for wireless communications are described that provide for timing adjustments that may be used in communications between wireless devices in a wireless communications system and signaling of such timing adjustments using physical layer signaling (e.g., layer 1 (L1) signaling). A first timing adjustment may be provided by a parent node to one or more associated child nodes that corresponds to a propagation delay between the parent node and its control node or a relay node through which the parent node communicates with a core network. In some cases, the physical layer signaling used to transmit the first timing adjustment may be a reference signal transmission, a downlink control information transmission, or any combination thereof.
Abstract:
Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a wireless communication device may receive information that identifies a time offset associated with backhaul physical random access channel (PRACH) resources. The time offset may be different from a time offset that is identified based at least in part on a PRACH configuration index The wireless communication device may identify a set of backhaul PRACH resources based at least in part on the time offset. The wireless communication device may transmit a RACH transmission using the identified set of backhaul PRACH resources. Numerous other aspects are provided.
Abstract:
The present disclosure presents a method and apparatus for controlling an uplink (UL) rate of one or more use equipments (UEs) served by a base station. For example, the method may include obtaining one or more measurements of a plurality of signals from a sub-set of the one or more UEs served by the base station over a period of time. Furthermore, such an example method may include comparing the measurements to one or more respective target values to generate a power activity indicator (PAI) metric and comparing the measurements to one or more respective target values to generate a power activity indicator (PAI) metric. As such, the uplink interference in heterogeneous networks may be controlled.
Abstract:
A system for measuring a rise-over-thermal (RoT) characteristic in a communication network includes controlling a transmitting station to maintain its transmit power at a substantially constant level for a first time interval, and measuring a first received power level. The transmitting station is then controlled to adjust its transmit power by a selectable amount for a second time interval, and a second received power level is measured. The first and second received power levels are then processed to determine the RoT characteristic.
Abstract:
A dynamic shared forward link channel (or "data" channel) is used to send multicast data to a group of wireless devices, e.g., using a common long code mask for the data channel. Reference power control (PC) bits are also sent on the data channel and used for signal quality estimation. A shared forward link control channel is used to send user-specific signaling to individual wireless devices, e.g., using time division multiplexing (TDM) and a unique long code mask for each wireless device. A shared forward link indicator channel is used to send reverse link (RL) PC bits to the wireless devices, e.g., using TDM. The data channel is jointly power controlled by all wireless devices receiving the data channel. The control and indicator channels are individually power controlled by each wireless device such that the signaling and RL PC bits sent on these channels for the wireless device are reliably received.
Abstract:
Adjusting a power control setpoint to compensate for imperfect signal detection in a communication channel capable of discontinuous transmission (DTX). The power control setpoint is compensated for false detections by adjusting the power control setpoint by a dynamically determined setpoint back off amount upon detection of a Good Frame. The amount of the setpoint back off is a function of the measured signal quality of the detected Good Frame and the number of Erasure indications received immediately preceding the Good Frame indication. In an alternative embodiment, an expected FER is scaled by one minus the probality of false DTX to compensate for the effects of false DTX. A state machine is implemented to compensate the setpoint for the effects of false erasure. The state machine estimates a number of false erasures by evaluating erasure detections in relation to consecutive DTX detections in the absence of good frame detections.
Abstract:
Aspects of the present disclosure provide techniques for addressing scenarios where the minimum transmit power supported by a wireless node (e.g., an Integrated Access and Backhaul (IAB) node) is above a minimum value specified by a standard. In some cases, the node may signal information regarding its power configuration so a network entity of the may take it into account (e.g., when allocating or scheduling resources). The power configuration may include an indication of the minimum transmit power supported by the node and/or an indication of a guard band that may help the IAB control adjacent channel leakage.
Abstract:
A configuration for local coordination between the child node and parent node to enable SDM communication between the parent and child node, without input or interaction from the CU. The apparatus receives, from a CU, an indication including an allocation of resources. The apparatus determines a type of communication with a second node based on the allocation of resources. The apparatus communicates with the second node based on the determined type of communication and utilizing the allocated resources. The apparatus coordinates with a parent node to utilize the allocated resources in a SDM operation between the child node and the parent node.
Abstract:
Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a central unit (CU) may receive, from a distributed unit (DU), a first DU configuration. The CU may transmit to the DU, a second DU configuration to change a DU configuration from the first DU configuration to the second DU configuration, the first DU configuration being different from the second DU configuration. The DU may override the first DU configuration to communicate in accordance with the second DU configuration. Numerous other aspects are provided.
