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 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.

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: 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.

Abstract: Disclosed are techniques for transmitting reference signals (RS) for positioning. A method comprises transmitting or providing an instruction to transmit a first set of RS to a user equipment (UE) in accordance with a first set of RS transmission parameters, receiving a report containing information indicating whether a measurement performed by the UE is limited by a signal-to-noise ratio (SNR) of the first set of RS or a bandwidth of the first set of RS, determining a second set of RS transmission parameters using the received report, wherein the second set of RS transmission parameters is different from the first set of RS transmission parameters, and transmitting a second set of RS to the UE in accordance with the second set of RS transmission parameters, or providing the second set of RS transmission parameters to a base station.

Abstract: Disclosed are techniques for computing and reporting a relevance metric for a positioning beacon beam. In an aspect, a first node receives, from a second node, a plurality of beams, determines a relevance metric for each of one or more beams of interest from the plurality of beams, wherein the relevance metric for each beam of the one or more beams of interest is based on a time of arrival at the first node of the beam and a signal strength of the beam, and sends, to the second node, a report identifying each of the one or more beams of interest and including the relevance metric for each of the one or more beams of interest.

Abstract: User equipment (UE)-specific information may be transmitted within a control resource set configured to carry resources common to UEs within a system. The UE-specific information may be associated with a search space having an aggregation level different from aggregation levels used with the common control resources and may occupy different modulation symbols within the common control resource set (e.g., to support flexible scheduling for multiple UEs). A base station and UE may operate in a system using one or more control resource sets within a system bandwidth. The UE may detect common control resources by monitoring decoding candidates in the control resource set according to a first set of aggregation levels. The UE may detect UE-specific control resources by monitoring decoding candidates in the control resource set according to other aggregation levels. The UE and base station may communicate based on control information obtained from the monitoring.

Abstract: A configurable new radio (NR) resource scheduling and indication transmission procedure that may be executed by a base station and a user equipment (UE) is disclosed. For example, a base station may determine a number of synchronization signal blocks available for transmission of non-scheduling data, and transmit an indication signifying at least one of the number of synchronization signal blocks or a location of each of the number of synchronization signal blocks. Further, a UE may receiving an indication signifying at least one of a number of synchronization signal blocks or a location of each of the number of synchronization signal blocks. The UE may further determine one or more resource elements forming the number of synchronization signal blocks where non-scheduling data has been scheduled for transmission. The UE may receive the non-scheduling data within the one or more resource elements forming the number of synchronization signal blocks.

Abstract: Methods, systems, and devices for wireless communication are described. A base station and user equipment (UE) may use subframe configurations that include dynamically scheduled channel state information reference signal (CSI-RS) symbols. For example, a base station may identify a subframe configuration that includes one or more sets of CSI-RS symbols of a subframe. The base station may indicate to a UE whether sets of CSI-RS symbols may be enabled or disabled during the subframe. The UE may receive multiple CSI-RSs at different locations within the subframe as indicated by the base station, and transmit CSI feedback to the base station based on at least one of the received CSI-RSs. In some examples, multiple base stations may coordinate the use of subframe configurations that include CSI-RS symbols that may be enabled or disabled.
