Abstract: Methods, systems, and devices for wireless communications are described in which different component carriers (CCs) or bandwidth parts (BWPs) of a system operating according to carrier aggregation may be configured with different transmission configuration indicator (TCI) states. A base station may transmit control information to a user equipment (UE) to activate two or more CCs, and that indicates two or more different sets of TCI states that are activated for the two or more CCs. The control information may be transmitted to the UE in a single MAC-CE. The single MAC-CE to activate different sets of TCI states at CCs or BWPs may allow for a reduced number of MAC-CEs used for conveying the set of active TCI states for the CCS or BWPs.

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: Aspects for user equipment (UE) based beam selection for beam failure recovery operations are disclosed. In one aspect, a method of wireless communication includes: identifying a beam failure event associated with a first beam and a secondary cell and transmitting a beam failure recovery request for the secondary cell. The method further includes selecting a second beam for secondary cell communications prior to receiving a response to the beam failure event, and transmitting or receiving a communication to or from the secondary cell using the selected second beam. Other aspects and features are also claimed and described.

Abstract: Aspects presented herein provide for improved measurement and management of interference for different subbands and different Tx beams for communication with the UEs. A UE may be configured to receive scheduling for communication with a base station in a first beam direction using a first subband. The UE may be configured to measure interference of a second subband for a second beam direction. The UE may be further configured to report the measured interference to the base station. A base station may be configured to schedule communication with the UE in the first beam direction using the first subband. The base station may be further configured to receive the report of interference measured by the UE on the second subband in the second beam direction.

IPC: H04W72/04
Abstract: Apparatuses and methods for wireless communication are provided. In an aspect, a user equipment (UE) receives a DCI from a base station, the DCI including an update to a periodically-occurring scheduling, where an absolute time for the update to take effect is specified in an RRC configuration of the DCI. The UE applies the update to the periodically-occurring scheduling for communications of the UE beginning at and following the absolute time. In another aspect, the UE receives at least one downlink communication that updates a plurality of SPS or CG parameters. The UE determines an action time for the update to take effect for each parameter, where the action time is a function of a type of each parameter. The UE applies the update to each parameter for communications of the UE beginning at and following a respective action time.

Abstract: In one aspect, a method of wireless communication includes transmitting, by a wireless communication device, a negative acknowledgement message (NACK) for a first Physical Downlink Shared Channel (PDSCH) via a first frequency band; and receiving, by the wireless communication device, a second PDSCH via a second frequency band, wherein the first frequency band is different from the second frequency band. Other aspects and features are also claimed and described.

Abstract: Methods, systems, and devices for wireless communication are described. A wireless device may identify an aggregation capability to communicate in parallel over a plurality of wireless links. The wireless device may in some cases broadcast this aggregation capability (e.g., periodically). Additionally or alternatively, the wireless device may transmit the aggregation capability in response to a request received from another wireless device. In some cases, the first wireless device may transmit a request to a second wireless device inquiring about aggregation capabilities of the second wireless device. The second wireless device may respond with its aggregation capabilities (e.g., or may broadcast its aggregation capabilities independently of receiving the response). The wireless devices may establish a multi-link session based at least in part on the indicated aggregation capabilities.

Abstract: Aspects of the present disclosure provide techniques for beam failure detection and related timing determinations, such as for applying a default beam after beam failure recovery response (BFRR) message. A method by a user equipment (UE) may include detecting failure of a beam associated with a first cell. The detecting can include performing beam failure detection (BFD) of a beam pair link (BPL) associated with the first cell (e.g., secondary cell (Scell)). The first cell can be in carrier aggregation (CA) with a second cell. The UE may send a beam failure recovery request (BFRQ) message on a second cell (e.g., a primary cell (Pcell)). The BFRQ message can include a candidate recovery beam for the first cell. The UE can receive a BFRR message on the second cell and determine a duration from reception of the BFRR message until using a default beam for communications on the first cell.
