Abstract: The present disclosure provides systems, devices, apparatus and methods, including computer programs encoded on storage media, for an autonomous fallback for a full-duplex beam pair. In a first aspect, a first wireless device may determine an occurrence of a performance trigger for a current beam pair for full-duplex communication at the first wireless device and use a fallback full-duplex beam pair in response to determining the occurrence of the performance trigger. In a second aspect, the first wireless device may receive an indication from a second wireless device of an occurrence of the performance trigger for the current beam pair for full-duplex communication and using the fallback full-duplex beam pair for communication with the second wireless device in response to receiving the indication.

Abstract: Frequency-selective single frequency network (SFN) operation is disclosed based on a modified Type-II port selection codebook. Within the channel state information (CSI) feedback procedure, a user equipment (UE) observing the CSI-reference signal (CSI-RS) resource configured by the serving base station with two ports configured over multiple sectors of the serving base station may select a precoder from the Type-II port selection codebook which accommodates additional subband amplitude information. The additional subband amplitude information may include a subband dynamic SFN activation indicator. In such a CSI report selected from the Type-II port selection codebook, the UE may indicate to the serving base station both a wideband SFN activation/deactivation and a subband SFN activation/deactivation in addition to the subband phase information. The serving base station may then use this CSI report to activate/deactivate SFN operations in both wideband and subband over each of the participating sectors.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine that the UE has data to transmit. The user equipment may transmit, to a base station (BS) and based at least in part on determining that the UE has the data to transmit, a plurality of communications on a plurality of uplink beams to trigger the BS to perform beam measurements for the uplink beams. The user equipment may receive information that identifies a subset of the plurality of uplink beams to be used for an uplink data transmission based at least in part on transmitting the communications. The user equipment may transmit the uplink data transmission on the subset of the uplink beams based at least in part on receiving the information that identifies the subset of the uplink beams. Numerous other aspects are provided.

Abstract: Certain aspects of the present disclosure provide techniques for configuring beam failure recovery operations. A method includes performing beam failure detection of a beam pair link associated with a secondary cell, wherein a user equipment (UE) is configured with one or more uplink control channel groups, each of the one or more uplink control channel groups comprising a corresponding plurality of component carriers where one of the corresponding plurality of component carriers is designated for communication of an uplink control channel for the corresponding uplink control channel group; determining one or more cells on which to send a beam failure recovery request (BFRQ) message based on a number of uplink control channel groups the UE is configured with; sending the BFRQ on the one or more cells; and receiving a beam failure recovery response message on at least one of the one or more cells.

Abstract: Certain aspects of the present disclosure provide techniques for transmitting simultaneous multi-beams on the same wireless resource. One example method includes determining a set of transmission (TX) beams for simultaneous transmissions to or from a user equipment (UE), signaling to the UE an indication of the TX beams, and transmitting simultaneously via the TX beams.

Abstract: Methods, systems, and devices for wireless communications are described that provide beam determination in beamformed wireless communications. A base station may transmit multiple repetitions of control information for a subsequent scheduled transmission. A user equipment (UE) may receive one of the multiple repetitions, determine the control information, and adjust beamforming parameters for the scheduled transmission. The UE may have a scheduling threshold that corresponds to a time needed for the UE to adjust beamforming parameters for the scheduled transmission, and the UE may identify the beamforming parameters for the scheduled transmission from any one of the multiple repetitions of control information, which may be transmitted using different downlink transmission beams, before or after the scheduling threshold, or combinations thereof.

Abstract: Methods, systems, and devices for wireless communications are described. A first device may transmit, to a second device, reference signals using combinations of analog beamforming parameters over multiple cycles. The reference signals may be transmitted for different combinations of transmit beamforming parameters and receive beamforming parameters over different cycles of the multiple cycles. The first device may receive, from the second device over the multiple cycles, a set of reports. Each report may indicate combinations of analog beamforming parameters selected for the analog beamforming parameters at the second device. Each combination of analog beamforming parameters may correspond to different cycles of the multiple cycles. The first device may set, for each radio frequency (RF) chain of a plurality of RF chains associated with the first device, a corresponding combination of analog beamforming parameters, and communicate with the second device via two or more beams based on the setting.

Abstract: Methods, systems, and devices for wireless communications are described that provide efficient beam updates in beamformed communications between a transmitting device and receiving device. The transmitting device and the receiving device may establish a connection using one or more beamformed transmission beams. The devices may periodically perform beam refinement procedures or beam training procedures and may update the transmission beams used for communications based on such procedures. Signaling to indicate the updated transmission beams may be transmitted that indicates one or more of a difference or delta from a prior beamforming parameter, a beam that was used at the receiving device for one or more measurements of a reference signal from the transmitting device, or any combinations thereof.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may transmit, to a base station such as a eNodeB (eNB), a next-generation NodeB or giga-NodeB (either of which may be referred to as a gNB)), an indication of a value of a channel quality parameter of a wireless link including a first beam pair between the UE and the base station. The UE may also transmit, to the base station, side information different from and in addition to the indication of the value of the channel quality information, and receive, in response to the transmitted indication of the value and the transmitted side information, an indication of resources for the UE to use to communicate on the wireless link.

Abstract: Methods, systems, and devices for wireless communications are described. A base station may transmit a first downlink grant (e.g., a PDCCH transmission) for a first data transmission (e.g., a PDSCH transmission) over a first component carrier; the first data transmission over a second component carrier; and a second downlink grant (e.g., another PDCCH transmission) for a second data transmission (e.g., another PDSCH transmission) over the second component carrier. A user equipment (UE) receives the first data transmission over a first beam and may use the first beam for receiving the second data transmission. Additionally or alternatively, the UE may receive a configuration message indicating a set of TCI states for downlink data transmissions to the UE; identify one or more reference signals monitor for beam failure detection (BFD), identify one or more BFD beams, monitor the identified one or more reference signals; and selectively trigger a beam failure reporting procedure.
