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.

Abstract: Methods, systems, and devices for wireless communication are described. A wireless device may identify a multi-link aggregation capability (e.g., a capability to transmit in parallel over multiple wireless links), and may transmit an indication of such capability to another wireless device. The indication may be included in an information element (e.g., a multi-band element) of a transmission frame. For example, the indication may be included in a multi-band element of a beacon, of association signaling, of probe signaling, of an add block acknowledgement (ADDBA) request, etc. The indication sent over one of the wireless links may include information for some or all the multiple links supported for multi-link aggregation. This information may include media access control (MAC) address, channel information, operating class, security information, etc. for each link. Such multi-link aggregation information may be used, for example, for establishment of improved block acknowledgment (BA) sessions between wireless devices.

Abstract: Methods, systems, and devices for wireless communications are described. Techniques described herein may provide power control configuration parameters using MAC-CE messaging. A base station may transmit a MAC-CE message that includes a power control configuration identifier. The UE may identify a power control configuration according to the power control configuration identifier. The power control configuration may include one or more power control parameters and a path loss reference signal identifier. The UE may update the path loss reference signal for an uplink transmission based on the received MAC-CE message and adjust power for performance of the uplink transmission according to one or more measurements of the updated path loss reference signal.
