Abstract: Aspects of the present disclosure provide techniques for beam and cell selection based on power configuration of a wireless node (e.g., an Integrated Access and Backhaul (IAB) node). In some cases, the node monitors synchronization signal block (SSB) transmissions from one or more network entities, and selects a beam or cell based on the monitoring and one or more metrics designed to limit potential interference caused by uplink transmissions from the first node.

Abstract: Methods, systems, and devices for wireless communication are described. Signaling of a radio frequency (RF) band associated with a synchronization signal (SS) block detected by a user equipment (UE) may be transmitted to a base station. For example, a base station may transmit a set of SS blocks to multiple UEs, where the SS blocks are frequency division multiplexed such that each SS block is transmitted in a respective RF band. A UE may receive one or more of the transmitted SS blocks and determine a preferred SS block from the received SS blocks. The UE may in turn transmit an message to the base station that indicates the RF band of the preferred SS block. In some cases, the base station may optionally transmit a request to the UE to transmit the indication of the RF band.

Abstract: The apparatus may be a first device at a first IAB node or the first IAB node itself. The IAB node may be configured to receive a configuration for a first set of reference signals associated with an IAB-MT function of the IAB node, wherein the first set of reference signals overlaps in time with a second set of time periods associated with an IAB-DU function of the IAB node. The IAB node may further be configured to extend an IAB-MT reference-signal measurement period based on the overlap between the first set of reference signals for measurement with the IAB-MT function of the IAB node and the second set of time periods associated with the IAB-DU function of the IAB node.

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: An apparatus may determine whether to indicate a beam failure recovery request to a base station using a contention-free RACH procedure with a dedicated preamble when the UE is timing unsynchronized with the base station. The apparatus may perform, when the apparatus is timing unsynchronized with the base station, the contention-free RACH procedure with the dedicated preamble to indicate the beam failure recovery request when the beam failure recovery request is determined to be indicated to the base station using the contention-free RACH procedure with the dedicated preamble. The apparatus may perform, when the apparatus is timing unsynchronized with the base station, a contention-based RACH procedure to indicate the beam failure recovery request when the beam failure recovery request is undetermined to be sent to the base station using the contention-free RACH procedure with the dedicated preamble.

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.

Abstract: Methods, systems, and devices for wireless communications are described that provide for signaling and switching of beam pair links (BPLs) for directional transmission beams between a base station and a user equipment (UE). A threshold value may be determined, which corresponds to an amount of time for a UE to receive and decode control information, and apply a different BPL than a current BPL that that is in use. The UE may maintain a BPL for data, which is used during data transmission time intervals (TTIs) until an indication is received to change the BPL for data. The UE and the base station may determine to change between BPLs based at least in part on the threshold value and a scheduling offset between a control channel transmission that allocates resources for a data TTI and a start of the data TTI.
