Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive a message that indicates a first initial uplink bandwidth part for use by the UE in communications with a network entity, the message also indicating a plurality of random access occasions, at least one of the plurality of random access occasions being in frequency resources that are outside of the first initial uplink bandwidth part. The UE may select a random access occasion of the plurality of random access occasions for transmission of a random access preamble from the UE to the network entity. The UE may transmit, as part of a random access procedure, the random access preamble within the random access occasion.

Abstract: Methods, systems, and devices for wireless communications are described. A synchronization signal block (SSB) may be dynamically scheduled within an operating bandwidth of a user equipment (UE), where the operating bandwidth of the UE is outside of a frequency resource in which a cell defining SSB (CD-SSB) is scheduled. For example, a UE may operate in a reduced capability mode or an enhanced reduced capability mode where the UE may operate in a narrower bandwidth than the serving cell bandwidth. Control signaling may dynamically configure an SSB for the UE within the operating bandwidth of the UE. The UE may monitor for the non-cell defining SSB (NCD-SSB) and skip monitoring for the CD-SSB based on the dynamically configured NCD-SSB. For example, a reduced capability UE or an enhanced reduced capability UE may monitor for the NCD-SSB without performing RF retuning between receiving the control signaling and monitoring for the NCD-SSB.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first wireless node may receive, from a second wireless node, a round-trip time timing advance indicator, wherein the round-trip time timing advance indicator is different from a timing advance indicator used for an uplink transmission timing advance message. In some aspects, the first wireless node may synchronize a timing configuration of the first wireless node to at least one of the second wireless node or a third wireless node based at least in part on the round-trip time timing advance indicator. Numerous other aspects are provided.

Abstract: Certain aspects of the present disclosure provide techniques for avoiding conflicts of resources assigned to one or more signals with resources assigned to Random Access Channel (RACH) in an Integrated Access and Backhaul (IAB) network. Configurations for first and second sets of signals are obtained for a first and second base station (BS) respectively. Based on the obtained configurations, a RACH configuration is determined for the first BS for performing a RACH procedure with the second BS over a wireless backhaul link, wherein one or more Physical RACH (PRACH) occasions according to the determined RACH configuration do not conflict with resources used for at least one of the first or the second set of signals. The determined RACH configuration is communicated to the second BS, wherein the second BS transmits a RACH signal to the first BS based on the determined RACH configuration.

Abstract: Aspects of the disclosure relate to a wireless user equipment (UE) establishing and utilizing a reference timing for a carrier or cell with multiple transmission and reception points (TRPs). A UE may receive a downlink signal on each of a plurality of component carriers (CCs), and determine respective timing events (e.g., slot boundaries, subframe boundaries, etc.) corresponding to each of the plurality of CCs. The UE may then determine a reference time for a first CC of the plurality of CCs. This reference time corresponds to a function of two or more timing events corresponding to different TRPs utilizing the first CC. The UE then determines a relative timing difference between the plurality of CCs based on this determined reference time. Other aspects, embodiments, and features are also claimed and described, including determining and utilizing a reference time on an uplink CC.

Abstract: A network management function of a relay network may identify relay node support of multi-mobile terminal (MT) operation, and may coordinate configuration of multiple backhaul links supported by the relay node via the multi-MT functionality of the relay node. In some cases, a relay node may transmit MT capabilities to the management function over a first established backhaul link, and the management function may configure a second backhaul link using a second MT function of the relay node. In other cases, the relay node may autonomously establish multi-MT connectivity based on preconfigured parent-selection policies, and the network management function may identify the relay node is dual-connected to the network management function. In either case, the network management function may configure backhaul routes (e.g., backhaul links) and resource configuration across the redundant topology.

Abstract: The present disclosure provides techniques for addressing switching times of Integrated Access and Backhaul (IAB) child nodes. For example, a parent IAB node may determine a switching time for the child IAB node to switch from transmitting on a backhaul/uplink to a parent node (with transmit power control) to transmitting on an access/downlink to a user equipment (UE) or other child IAB node. The parent IAB node may then configure the IAB child node according to the determined switching time (e.g., by scheduling the IAB child node accordingly or setting one or more timing advance parameters).

Abstract: Certain aspects of the present disclosure relate to communication systems, and more particularly, to interpreting a timing advance (TA) command for members of a timing advance group (TAG), such as different uplink component carriers and/or different bandwidth parts, having different numerologies, such as different subarrier spacing (SCS). A method that may be performed by a user equipment (UE) includes receiving, from a base station (BS), a TA command. The UE interprets the TA command differently for different members of a same TAG, associated with different numerologies. The UE applies a timing adjustment when transmitting an uplink transmission to the BS based, at least in part, on the interpretation.

Abstract: Methods, systems, and devices for wireless communication are described. A network device, such as a base station, may transmit a request message to a user equipment (UE). The request message may include a request for the UE to transmit a set of sounding reference signals (SRSs). The set of SRSs may include two (or more) beamformed signals. The network device may receive the set of SRSs according to the request message. The network device may identify, based on a co-phasing parameter associated with the two (or more) beamformed signals, an antenna port precoder configuration to use for communicating with the UE.
