Abstract: A beam failure caused by an event initiated by the UE such as folding of the UE or shutting down of a UE antenna penal may be predictable. Accordingly, the UE may declare a beam failure detection (BFD) without going through a potentially long detection procedure. Disclosed herein are apparatus and methods for detecting beam failure and terminating BFD earlier than the current DFD process would have. The method may include identifying a beam failure (BF) event at the UE that impacts at least one beam pair link (BPL) and communicating a request to an associated base station to stop communicating on an impacted beam pair link, without going through an entire BFD process.

Abstract: There may be a gap between the time a beam pair link (BPL) impacted by a beam failure (BF) event is deactivated and the time a replacement BPL is activated and becomes fully functional at a UE. The gap may be called a blackout period. A base station may not know the blackout period and may continue transmitting to the UE on the impacted BPL during the blackout period. This may result in a transmission failure. Disclosed herein are apparatus and methods for determining a blackout period associated with a beam failure (BF) event and communicating a blackout indication to a base station, the blackout indication including the blackout period.

Abstract: Systems and methods establishing and maintain a direct User Equipment to User Equipment communication link in a gNB are disclosed. A gNB may determine that direct UE to UE link should be established in a cell. The gNB may transmit information to a first and second UE to enable a device to device beam search procedure. The first and second UE may perform the beam search and report the result to the gNB. The gNB may determine the appropriate beam for the first and second UE to establish a communication link.

Abstract: Certain aspects of the present disclosure provide techniques for user equipment (UE) antenna grouping for uplink transmission, such as dynamic antenna grouping for uplink transmission using multiple transmission configurations. A method that may be performed by a UE includes grouping one or more UE antennas into one or more groups and sending an indication of the one or more groups to a base station (BS). Another method that may be performed by a UE includes receiving an indication from a BS to group one or more UE antennas and grouping the one or more UE antennas based on the indication.

Abstract: A method, apparatus, and computer readable medium for wireless communications for receiving, by a network entity from a user equipment (UE), a component carrier/bandwidth portion (CC/BWP) grouping capability message that indicates a capability of the UE to support CC/BWP group-based signaling; transmitting, by the network entity to the UE, a CC/BWP grouping indication that identifies at least one CC/BWP group based on the CC/BWP grouping capability message; transmitting, by the network entity to the UE, a CC/BWP configuration message that includes CC/BWP group configuration information that identifies a CC/BWP group configuration for the at least one CC/BWP group; communicating, by the network entity with the UE, on at least one CC/BWP of the at least one CC/BWP group based on one or more communication parameters configured according to the CC/BWP group configuration.

Abstract: Methods, systems, and devices for wireless communications provide for identification of multiple antenna panels at a user equipment (UE), and determination of panel-specific capabilities for the multiple antenna panels. A UE may determine whether simultaneous communications using two or more antenna panels is supported. The UE may determine that simultaneous communications using two or more antenna panels is supported based on a predetermined rule that indicates such simultaneous communications are supported or unsupported. Whether simultaneous communications on multiple panels is supported may be dependent upon a capability of the UE. The UE may transmit panel-specific capabilities to the base station, that may be used by the base station for subsequent communications between the UE and the base station.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive control information indicating a resource allocation pattern for a downlink transmission that is configured for transmission using a plurality of beams and a plurality of mini-slots, where a duration of a mini-slot is less than a duration of a slot. The UE may identify a start time of a first mini-slot of the plurality of mini-slots and a length of the first mini-slot based on the resource allocation pattern, and receive the downlink transmission based on the start time of the first mini-slot and the length of the first mini-slot.

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: Control for multi-panel user equipment (MPUE) activation may be performed by both the MPUE and a base station. The MPUE may have at least a first panel and a second panel. The MPUE may send to the base station, a request to change an activation status of at least one panel of the MPUE. The base station may transmit a response indicating whether the request has been approved. The MPUE may change the activation status of the panel according to the response. Conversely, the MPUE may receive a command from the base station to change an activation status of at least one panel of the MPUE. The MPUE may determine whether to follow the command or override the command. The MPUE may transmit a response indicating whether the MPUEUE has followed the command or overridden the command.
