Abstract: The apparatus determines, for a CC, an active TCI state of at least one of a CORESET of a PDCCH when the CORESET is configured on the CC or a PDSCH. In addition, the apparatus determines, based on the determined active TCI state, a default beam on the CC for transmitting at least one of a PUCCH or SRS. Further, the apparatus transmits at least one of the PUCCH or the SRS through the determined default beam on the CC.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, via a first carrier, an indication of an offset for scheduling a reference signal on a second carrier, wherein the offset indicates a duration between downlink control information (DCI), that schedules the reference signal, and the reference signal; determine a first numerology of the first carrier and a second numerology of the second carrier; and determine a time offset for the reference signal based at least in part on the offset and at least one of the first numerology, the second numerology, or both the first numerology and the second numerology. Numerous other aspects are provided.

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: Methods, systems, and devices for wireless communications are described for multiple-input multiple-output (MIMO) millimeter wave (mmW) communications of two or more MIMO streams via two or more beams. A sequential technique may be used for configuring MIMO communications, in which analog RF beamforming parameters are determined based on reference signal measurements during a beam sweeping procedure. Then, digital baseband beamforming parameters may be determined and used for baseband processing of two or more MIMO streams. The digital baseband beamforming parameters may include baseband precoding parameters used for transmitting the two or more MIMO streams on the two or more beams, and baseband combiner parameters used for receiving the two or more MIMO streams on the two or more beams.

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.

Abstract: Wireless devices may employ techniques for indicating alternative modulation coding schemes (MCSs) (e.g., MCS values or MCS indices not associated with a default list or default MCS table). That is, communications (e.g., such as physical downlink control channel (PDCCH) transmissions carrying downlink control information (DCI), physical downlink shared channel (PDSCH) transmissions carrying uplink grants, etc.) may include information (e.g., in MCS fields and reserved fields) that indicate alternative MCSs for subsequent communications. For example, random access radio network temporary identifier (RA-RNTI) scrambled DCI, random access response (RAR) messages, etc., may indicate an alternative MCS for subsequent messages in a random access procedure (e.g., for a RAR, an RRC connection request, etc.). The alternative MCS may be conveyed by indicating information such as MCS scaling factors, alternative MCS table IDs, MCS indices associated with the alternative MCS table, or some combination thereof.
