Abstract: Methods, systems, and devices for wireless communications are described in which a narrowband device may communicate in a wireless communications network according to frequency hopping techniques. Devices using narrowband communications and frequency hopping techniques may maintain separate radio link monitoring (RLM) processes, beam failure detection (BFD) processes, beam failure recovery (BFR) processes, or combinations thereof, for multiple bandwidth parts (BWPs) or hop regions of a full channel bandwidth. Such separate processes may provide for enhanced estimates of beam failures per BWP or hop region, which may be used to enhance communications reliability.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive signaling indicating a configuration for communicating to the UE a random access response of a random access procedure. The configuration may indicate a first quantity of instances of control information associated with the random access response in a set of slots and a portion of the time window configured for the first quantity of instances. The UE may monitor the set of slots for instances of the control information and receive a second quantity of instances of the control information for the UE in a first subset of slots of the set of slots. The second quantity of instances may be less than the first quantity of instances. The UE may combine the instances of the control information from the first subset of slots and decode the random access response based on combining the instances.

Abstract: Certain aspects of the present disclosure relate to methods and apparatus for providing beam switch latency using communications systems operating according to new radio (NR) technologies. For example, the method generally includes determining a latency associated with a beam switch from a source antenna array module to a target antenna array module when the target module is in a low power mode; and signaling a base station to use the determined latency after sending a command for the beam switch.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may support channel state information (CSI) operations, such as CSI reporting. A UE may identify a change in CSI pertaining to communications with a base station or any other change in communications with a base station. The UE may transmit, to the base station and based on the change in CSI, a CSI scheduling request, which may include an indication to activate or grant resources for a CSI report transmission from the UE to the base station. The UE may receive, from the base station, a CSI report trigger based on the CSI scheduling request, and transmit, in response to receipt of the CSI report trigger, a CSI report over a physical layer uplink channel (e.g., a physical uplink shared channel (PUSCH)).

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may establish a first connection with a source base station. The UE may determine that a handover procedure is being performed for establishing a second connection with a target base station. The UE may monitor, during a monitoring period instantiated at a physical layer of a protocol stack of the UE, for a control signal acknowledging success of the handover procedure from a target base station. The UE may transmit, based at least in part on a result of the monitoring during the monitoring period, a physical layer signal or a medium access control layer signal to the source base station indicating that the handover procedure was unsuccessful based at least in part on a failure to successfully receive and decode the control signal.

Abstract: An aspect of the present disclosure includes methods, systems, and computer-readable media for receiving a beam failure detection reference signal configuration, detecting an absence of a configured and quasi-co-located beam failure detection reference signal in a monitored control resource set (CORESET), and utilizing reference signals indicated in the CORESET transmission configuration indicator state for beam failure detection.

Abstract: A user equipment (UE) measures, for each of at least one beam of each of at least one neighboring cell of a UE, at least one reference signal (RS) to obtain at least one layer 1 (L1) beam measurement. The UE derives, for each neighboring cell based on each L1 beam measurement corresponding to the each neighboring cell, at least one L1 measurement reporting value. The transmits, to a serving cell serving the UE 104, a report based on each derived L1 measurement reporting value.

Abstract: Methods, systems, and devices for wireless communication are described. Generally, the described techniques provide for reporting content processing times to a base station to allow the base station to efficiently schedule bi-directional communications one or more UEs. A content processing time may correspond to the time taken by a UE to process one or more downlink signals received in one or more downlink transmissions. In some examples, the UE may report a content processing time for each downlink transmission. In some examples, the UE may report one or more content processing times for multiple downlink transmissions. The base station may use the content processing times to configure an appropriate gap between downlink and uplink transmissions such that the UE may have sufficient time to process downlink signals before transmitting one or more uplink transmissions in response to the one or more downlink transmissions.

Abstract: Search space-BFR time occasions may overlap with other search space occasions. Additionally, if any CORESET other than a CORESET-BFR has lowest CORESET ID, the UE will prioritize receiving that CORESET and may miss the BFR response. Accordingly, assigning a priority to CORESETs or search spaces during BFR may be preferable. In an aspect of the disclosure, a method, a computer-readable medium, and an apparatus are provided. The apparatus may allocate a set of time-frequency resources to a plurality of CORESETs or a plurality of search spaces. The apparatus may assign a priority to each of the plurality of CORESETs or the plurality of search spaces. The apparatus may assign a highest priority to a CORESET for BFR or a search space for BFR.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive control signaling that configures a channel measurement resource and an interference measurement resource within a same time interval. The UE may transmit a measurement report that indicates a signal to interference plus noise ratio (SINR) measurement that is generated based on measuring the channel measurement resource and the interference measurement resource. In some cases, the UE may receive a quasi co-location (QCL) relationship indicator that indicates a QCL relationship for the interference measurement resource or the channel measurement resource. The UE may measure the channel measurement resource and the interference measurement resource in accordance with the QCL relationship.
