Abstract: Cell reselection and other operations involving signal measurements at a UE may increase the power consumption and operation complexity at a UE, such as a reduced capacity UE (RedCap UE). In some scenarios, for example, a UE may need to frequently switch to bandwidth parts (BWPs) outside the bandwidth of its initial DL bandwidth part to receive and measure synchronization signal blocks (SSBs) for cell reselection, which increases the power consumption of the UE. The aspects described herein allow a UE to measure SSBs in one or more bandwidth parts that is not an initial DL bandwidth part configured by a serving cell of the UE in response to an event trigger or a message received at the UE. The SSBs may be associated with the serving cell of the UE or with a non-serving cell. The UE performs a cell reselection operation based on the measurements.

Abstract: Methods, systems, and devices for wireless communications are described that provide for resource allocation in an integrated access and backhaul (IAB) network. A relay node in an IAB network may be assigned a first resource partition that is different from a second resource partition for the child and parent nodes. Based on a resource configuration (e.g., for a slot) of the second resource partition, the relay node may opportunistically utilize the second resource partition for communications. For instance, the relay node may determine a direction table based on the resource configurations of the child and parent nodes, which may be used to perform uplink or downlink communications in one or more symbols of the second resource partition. The relay node may also identify flexible symbols as free or non-free when determining the direction table.

Abstract: Techniques are described for wireless communication. In one method, a user equipment (UE) receives a timing synchronization signal (TSS) and a physical broadcast channel (PBCH), with the TSS based at least in part on a timing of the TSS within a broadcast channel transmission time interval (BCH TTI); determines the timing of the TSS within the BCH TTI; and demodulates the PBCH based at least in part on the TSS. In another method, a base station allocates resources for a TSS and a PBCH within a BCH TTI; determines the TSS based at least in part on a timing of the TSS within the BCH TTI; and transmits, on the resources allocated for the TSS and the PBCH, the TSS and the PBCH, with the TSS transmitted as a demodulation reference signal (DMRS) for the PBCH on at least one port used to transmit the TSS and the PBCH.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive an indication of a set of synchronization signal blocks (SSBs). The UE may receive an indication of a set of physical cell identifiers (PCIs) associated with the set of SSBs, wherein the set of PCIs are stored in association with the set of SSBs. The UE may refrain from performing a measurement on a first SSB, in the set of SSBs, wherein the first SSB is associated with a same PCI, in the set of PCIs, as a second SSB that is included in the set of SSBs and is measured. Numerous other aspects are described.

Abstract: Methods, systems, and devices for wireless communications are described. A node (e.g., a base station or network entity) may identify a signal that provides an indication of a location of a contention free random access channel (CFRA) resource within a time region and an indication of a timing pattern for the CFRA resource, the timing pattern associated with a pattern of subsequent instances of the time region in which the CFRA resource is repeated, wherein the CFRA resource is not a fully overlapping resource with respect to a contention based random access (CBRA) resource. The node may convey the signal to one or more user equipment (UE) to indicate the location and the timing pattern.

Abstract: Certain aspects of the present disclosure provide techniques for beam refinement. A base station provides information regarding what transmit beams are used to transmit different reference signal (RS) resources. In some cases, the information indicates whether a same transmit beam is used to transmit a set of RS resources (e.g., symbol, sub-symbol, or frequency resources) or whether different transmit beams are used to transmit the set of RS resources.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may identify that an uplink transmission to a base station is to occur in accordance with an uplink timing advance value representing an amount of time that the uplink transmission takes from transmission at the UE to reception at the base station. The UE may perform an autonomous open-loop adjustment to the uplink timing advance value. The UE may transmit the uplink transmission to the base station in accordance with the adjusted uplink timing advance value. The base station may transmit an indication of a set of uplink timing advance values for a UE to use for uplink transmissions, each of the set of uplink timing advance values representing an amount of time that an uplink transmission is expected to take from transmission at the UE to reception at the base station.
