Abstract: Systems, methods, and apparatuses for performing a beam recovery procedure using a second CC are disclosed. A UE may perform a beam recovery procedure using two component carriers (CCs): for example, first component carrier may be a beam formed millimeter wave (MMW) carrier having a beam recovery procedure and second component carrier may be an assisting carrier such as a sub-6 GHz carrier or a different MMW carrier. In a first example, a UE may trigger beam recovery for first component carrier (on second component carrier), generate a beam measurement report, and transmit the beam report on resources allocated for uplink transmission on second component carrier. In a second example, a new scheduling request (SR) may be defined on first component carrier for second component carrier beam recovery. In a third example, RACH resources or procedures on second component carrier may be used to perform the beam recovery for first component carrier.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may detect beam failure on a secondary cell (SCell), wherein the UE is configured with a primary cell (PCell) and the SCell for carrier aggregation with a base station; identify an order in which multiple procedures for transmitting a beam failure recovery request are to be attempted, wherein the multiple procedures include at least one of: a procedure for transmitting the beam failure recovery request via the PCell, a procedure for transmitting the beam failure recovery request via one or more SCells configured for the UE, or a combination thereof; and transmit the beam failure recovery request to the base station using a first procedure, of the multiple procedures, based at least in part on the order. Numerous other aspects are provided.

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: Methods, systems, and devices for wireless communications are described. In some examples, a random access occasion may overlap in time with a synchronization signal block resource, where the random access occasion and the synchronization signal block resource have a same index. In some such examples, a base station may transmit, to a user equipment (UE), an indicator of a mapping of the random access occasion to an uplink beam that is associated with a synchronization signal block resource with a different index than the random access occasion. The UE may transmit, to the base station, a random access preamble over the random access occasion using the uplink beam.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may transmit, to a base station, feedback information that indicates delay spread information. The UE may receive control signaling that indicates to use a first waveform of a set of different waveforms for a first data transmission via a first beam based on the feedback information. The UE may then communicate the first data transmission via the first beam using the first waveform

Abstract: A configuration for inter-cell interference coordination in wireless communication systems. The apparatus determines a priority order of a first base station to schedule a first transmission with a first UE. The apparatus transmits a first transmission request to the first UE to schedule the first transmission. The apparatus receives, from the first UE, a measurement report based on the first transmission request received by the first UE, the measurement report indicates a signal quality of the first transmission request. The apparatus determines to schedule the first transmission with the first UE based at least on the measurement report. The apparatus sends a schedule indication to at least a second base station indicating whether the first transmission is scheduled with the first UE, at least the second base station has a lower priority order than the first base station.

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.
