Abstract: A user equipment (UE) having a first capability associated with a lower maximum UE bandwidth than a second capability receives information for initial access using a first initial downlink bandwidth part (BWP) that is shared among UEs having the first capability and UEs having the second capability. The UE transmits a random access message in an initial uplink BWP that is dedicated for the UEs having the first capability.

Abstract: This disclosure provides systems, methods and apparatus, including computer programs encoded on computer storage media for a reduced capability (RedCap) user equipment (UE) and supporting cell. The RedCap UE is configured with multiple bandwidth parts (BWPs). A maximum bandwidth of the RedCap UE is lower than a maximum bandwidth of a non-RedCap UEs. The UE receives a cell-defining synchronization signal block (CD-SSB) that defines a shared initial downlink BWP for RedCap UEs and non-RedCap UEs. The UE switches to a separate initial downlink BWP for RedCap UEs. The UE accesses the cell via the separate initial downlink BWP. The UE receives a configuration of an active downlink BWP for RedCap UEs. The UE determines whether to switch from the active downlink BWP to the shared initial BWP or the separate initial downlink BWP to obtain information such as updated system information, system measurements, and uplink configuration information.

Abstract: A repeater BWP switching schedule is provided for a repeater that is responsive to a user equipment BWP switching schedule. Should the repeater support a plurality of active user equipments, the user equipment BWP switching schedule is a superset of the BWP switching schedule for each individual user equipment. The repeater BWP switching schedule may thus be more granular than the UE BWP switching schedule.

Abstract: Certain aspects of the present disclosure provide techniques for wireless communications by a user equipment (UE). The UE detects at least one of a first type of reference signal (RS) or a second type of RS within an active bandwidth part (BWP). The UE then derives uplink (UL) transmission timing and corresponding accuracy requirement, based on which type of RS was detected. The UE then transmits UL signals based on the derived UL transmission timing and the corresponding accuracy requirement.

Abstract: Wireless communications systems and methods related to the timing arrangements and the transmission gap configurations in 2-step random access channel (RACH) procedures to improve system latency and reliability of a RACH HARQ process are provided. The UE transmits a first message including a random access preamble and a payload, and then monitors for a second message in response to the first message during a random access response (RAR) window. In response to determining that no second message is received by the UE from the BS or a back off indicator is received within the RAR window, the UE re-transmits the preamble and payload of the first message after the RAR window lapses. In response to determining if the second message received within the RAR window carries a FallbackRAR or SuccessRAR, the UE then determines to re-transmit the payload of the first message based on the FallbackRAR, or to transmit an acknowledgement message based on the SuccessRAR.

Abstract: Disclosed are techniques for wireless communication. In an aspect, a base station may determine a transmit power to be used by a downstream node or an amplification gain to be used by the downstream node when relaying or repeating messages to a target node. The base station may transmit, to the downstream node, a message intended for the target node, the message having an indicated transmit power, wherein the message intended for the target node is transmitted by the base station using an actual transmit power. In some aspects, the indicated transmit power is the transmit power to be used by the downstream node, so that when the message intended for the target node is repeated by the downstream node, the indicated transmit power of the repeated message matches the actual transmit power of the repeated message.

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: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a central entity may determine a set of schedulable resources for a plurality of links associated with a plurality of nodes of a multi-link network; and may provide scheduling information to the plurality of nodes to schedule communication on the plurality of links based at least in part on determining the set of schedulable resources. In some aspects, a node of a network may determine an extended slot format indicator for the node based at least in part on a received extended slot format indicator of a parent node of the node and a received null adjust request from a child node of the node; may provide the determined extended slot format indicator to the child node; and may provide the received null adjust request to the parent node. Numerous other aspects are provided.

Abstract: A first apparatus may determine a first schedule associated with the one or more repetitions of the control information on the control channel based on the first information. The first apparatus may receive, from the network, at least one of the one or more repetitions of the control information on the control channel based on the first schedule, wherein the control information indicates a second schedule associated with a random access response (RAR) on a data channel. The first apparatus may receive, from the network, the RAR on the data channel based on the second schedule.
