    Abstract: Methods, systems, and devices for wireless communications are described. For example, the described techniques provide for configuring sidelink beam failure detection reference signals for determining beam failures on a sidelink between a first sidelink user equipment (UE) and a second sidelink UE. The first UE may determine a first set of sidelink beam failure detection reference signals to transmit to the second UE and a second set of sidelink beam failure detection reference signals to receive from the second UE. The first UE may transmit the first set to the second UE using a set of sidelink transmit beams. The first UE may further monitor for the determined second set using a set of sidelink receive beams. Based on the first and second set of sidelink beam failure detection reference signals, the first and second UE may communicate over the sidelink.

    Abstract: Methods, systems, and devices for wireless communications are described. A transmitter may identify a set of one or more packets for broadcast to a set of one or more user equipments (UEs) and transmit a set of one or more network encoded packets based on the set of one or more packets. The UEs may each rebroadcast one or more successfully received network encoded packets via sidelink communications. Each UE may report to the original transmitter via feedback indicating the one or more successfully received packets at each UE. The transmitter may generate an updated set of one or more network encoded packets based on the feedback from the UEs. The transmitter may continue to update and transmit the updated set of one or more network encoded packets based on feedback until the transmitter determines that each UE has recovered the set of one or more packets.

    Abstract: Methods, systems, and devices for wireless communications are described to support transmission of a resource modification information request from a user equipment (UE) to a base station, where the resource modification request may request an increased density of uplink transmission occasions. For example, the resource modification request may request an increase from a first density of uplink transmission occasions configured for the UE. The resource modification request may include a request for a decreased periodicity of uplink transmission occasions, an increased number of groups of repetitions for uplink transmission occasions, an increased number of resource blocks for uplink transmission occasions, or an increased modulation coding scheme for uplink transmission occasions. The base station may receive the resource modification request and may transmit a message to the UE, which may indicate a modified or new uplink grant configuration for uplink transmission occasions having a higher density (e.g., a second density).

    Abstract: Methods, systems, and devices for wireless communications are described. Generally, the described techniques at a user equipment (UE) provide for efficiently identifying a dormancy state of a secondary cell (SCell) configured for communications with a base station. A UE may be configured with a duration of time for which an SCell is to be in an indicated dormancy state. Accordingly, when the UE receives an indication of a dormancy state for an SCell, the UE may determine that the SCell is in the indicated dormancy state for the duration of time. The UE may also be configured with a default dormancy state of the SCell. Thus, after the duration of time expires, the UE may determine that the SCell is in the default dormancy state (e.g., the UE may fall back to the default dormancy of the SCell after the duration of time expires).

    Abstract: Methods, systems, and devices are described for wireless communication. A transmitting device may send a signal including multiple transport blocks corresponding to multiple simultaneous hybrid automatic repeat request (HARQ) processes. Additional control information may be used to support the multiple simultaneous HARQ processes. For instance, the additional control information may indicate the number of available HARQ processes, an activity state for each HARQ process (e.g., active new data, active retransmission, or inactive), and the redundancy versions of each HARQ process. In some cases, the additional control information may be included in a downlink grant. A receiving device may respond with an acknowledgement or negative acknowledgment (ACK/NACK) for each of the transport blocks. The transmitting device may identify a retransmission status for each HARQ process based on the ACK/NACKs, and transmit new redundancy versions (or new data) to the receiving device.

    Abstract: Techniques for wireless communication are described, which may include establishing a connection, by a user equipment (UE), with a first and second evolved NodeB (eNB), wherein each of the eNBs provide radio resources to the UE for respective uplink communications; receiving from the first eNB, at the UE, an indication including an allocation of uplink transmit power between the first eNB and at least the second eNB; and transmitting the uplink communications from the UE to the first and second eNBs based on the indication. The techniques may further include coordinating, by a first eNB, multi-connectivity communication for a UE with at least the first eNB and a second eNB; determining for the UE, at the eNB, an allocation of uplink transmit power between the first eNB and at least the second eNB; and transmitting an indication including the allocation of uplink transmit power allocation from the first eNB to the UE.
