Abstract: An apparatus may determine a beam configuration for a data transmission that includes at least one code block in a first resource block. In certain aspects, the at least one code block may include a first set of bits and a second set of bits. In certain aspects, the beam configuration may include a first beam in a first beam direction that may be used to communicate the first set of bits of the at least one code block in a first set of symbols of the first resource block and a second beam in a second beam direction that is used to communicate the second set of bits of the at least one code block in the second set of symbols of the first resource block. The apparatus may transmit signaling that indicates the beam configuration for the data transmission in the first resource block to a UE.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive, in a control channel, a first grant identifying a first set of resources of a first data channel on which the UE is to monitor for one or more second grants, the first data channel being downlink. The UE may monitor the first set of resources in the first data channel for the one or more second grants, the one or more second grants identifying a second set of resources of a second data channel on which the UE is to perform data communications. The UE may transmit, based at least in part on the monitoring the first set of resources, a feedback message associated with receipt of the one or more second grants.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) in communication with a serving base station may identify that the UE is a potential victim of interference from a neighboring base station. The UE may transmit an interference coordination message to the neighboring base station. The interference coordination message may request modification of one or more transmission parameters at the neighboring base station. The neighboring base station may modify its transmission parameters to decrease interference with the UE, and the UE may communicate with the serving base station after transmitting the interference coordination message.

Abstract: Wireless communications systems and methods related to signaling medium reservation information medium sharing among multiple radio technologies (RATs) are provided. A wireless communication device of a first RAT detects a channel reservation signal of a second RAT in a spectrum shared by the first RAT and the second RAT. The wireless communication device determines whether the channel reservation signal indicates a first transmission opportunity (TXOP) duration or a second TXOP duration that is different from the first TXOP duration. The wireless communication device selects, based on the determination, at least one of performing a backoff or continuing to monitor the spectrum.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive a plurality of downlink grants for a corresponding plurality of data transmissions, wherein each downlink grant identifies resources for receiving the corresponding data transmission and indicates whether the corresponding data transmission comprises a last data transmission for a reporting occasion. The UE may determine, based at least in part on the received downlink grants, that a last downlink grant for the last data transmission associated with the reporting occasion was not received. The UE may transmit a feedback report during the reporting occasion, wherein a format of the feedback report is based at least in part on the last downlink grant for the last data transmission not being received.

Abstract: A method, an apparatus, and a computer program product for wireless communication are provided. The apparatus may be a UE. The UE determines CSI. The UE determines whether to send the CSI based on at least one of a timer or a threshold. The UE sends the CSI upon determining to send the CSI. The UE may send the CSI in a MAC header upon determining to send the CSI. When the UE determines whether to send the CSI based on the threshold, the UE may determine whether to send the CSI based on a difference between the CSI and reference CSI. The UE may determine the reference CSI based on at least one of previously reported CSI, fixed CSI, or an MCS of a received data transmission from a base station. The UE may send CSI to the base station in an initial connection setup with the base station.

Abstract: Methods, systems, and devices for wireless communication are described. A first wireless device may receive a clear to send signal based precoded based at least in part on a receive filter at a second wireless device. The first wireless device may calculate a transmit precoder based at least in part on the clear to send signal. For example, the first wireless device may calculate a whitening filter and a second filter based at least in part on the clear to send signal. The first wireless device may transmit a request to send signal precoded by the transmit precoder to initiate communications with a third wireless device without significantly interfering with ongoing communications at the second wireless device.

Abstract: Methods, systems, and devices for wireless communications are described. A base station may determine a set of power control parameters for a user equipment (UE) to use in different power control loops. The base station may indicate a power control process for the UE to perform in downlink control information. The UE may identify a subset of the power control parameters to use in a power control loop for the indicated process. In some examples, the power control parameters may be for different sounding reference signal processes, such as uplink channel sounding, downlink channel sounding with channel reciprocity, or cross-link interference. In some other examples, the power control parameters may be for power control loops of different uplink channel configuration. The base station may convey the set of power control parameters to the UE by radio resource control signaling.
