Abstract: Methods, systems, and devices for wireless communications are described that provide for managing transmissions using multiple component carriers (CCs) in which transmissions using one or more of the CCs may span less than a full transmission time of a slot or other transmission time interval. A UE may signal a capability to transmit such transmissions, and one or more capabilities related to carrier aggregation that may be used by a base station for scheduling of transmissions on different CCs. In the event that overlapping transmissions on two or more CCs exceed a maximum power threshold, various techniques for dropping at least a portion of one or more transmissions of one or more CCs are described.

Abstract: Certain aspects of the present disclosure generally relate to wireless communications, and more specifically to increased diversity for devices with limited communications resources. An example method generally includes transmitting data as a bundled transmission to a device with limited communications resources, the bundled transmission comprising multiple bursts wherein each burst spans a plurality of transmission time intervals (TTIs) and the same data is transmitted in each burst, and taking action to increase diversity (e.g., at least one of spatial diversity, time diversity, frequency diversity, etc.) for the bundled transmission.

Abstract: A UE may be configured for half-duplex communications. An access point may configure half-duplex UEs for efficient resource utilization using two or more different half-duplex configurations that include different timing for channels in different directions. A UE may determine a half-duplex configuration for use in communicating with the access point, each slot of the half-duplex configuration including at least a PDCCH on a downlink frequency and an uplink short burst on an uplink frequency, and each slot associated with a HARQ timeline. The UE may determine a direction for a slot. The UE may transmit or receive according to the direction for the slot and the half-duplex configuration.

Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE) may transmit uplink (UL) messages in unlicensed spectrum with a reduced UL timing delay. The UL timing delay may be reduced by using a shortened transmission time interval (TTI) (e.g., a TTI that is reduced in duration relative to other TTIs in the system or in a legacy system) or by reducing the number of TTIs between a grant and the corresponding UL message. The reduced UL timing delay may decrease the likelihood that the UE will wait for a subsequent transmit opportunity (TxOp) to transmit the UL message. In some cases, the reduced UL timing delay corresponds to a reduced hybrid automatic repeat request (HARM) processing delay. In some cases, a time difference (e.g., measured in TTIs) between a measurement reference TTI a corresponding channel state information (CSI) report may also be reduced.

Abstract: Enhanced channel state information (CSI) feedback is disclosed for full dimensional multiple input, multiple output (FD-MIMO) operations. In one aspect, a single CSI process is defined that is configured with an azimuth and elevation CSI-reference signal (RS) ports. A user equipment (UE) will send a precoding matrix indictor (PMI) report including a precoding matrix indicator (PMI) for the azimuth ports and a PMI for the elevation ports. One of the PMIs is assigned a low rank. The base station will use the two PMIs to create a whole channel precoding matrix. In another aspect, a single CSI process is configured having a plurality of CSI-RS resources. The UE generates channel measurement information for each of the CSI-RS resources, but only sets a CSI report to the base station of a subset of the total number of resources.

Abstract: Methods, systems, and devices for wireless communications are described to enable a user equipment (UE) to determine a rate-matching scheme or a feedback scheme for overlapping downlink transmission resources. A collision handling scheme may enable the UE to de-rate match a second, higher priority downlink shared channel independent of another rate-matching pattern or indicator for other shared channels, such as a first, overlapping downlink shared channel. The UE may determine to de-rate match the second channel around resources indicated within control signaling or higher-layer signaling associated with the second channel. The collision scheme may provide for the UE to generate an acknowledgement bit for feedback for one or more portions of the first channel that are preempted by the second channel and generate other feedback for non-preempted portions. A base station may keep track of preempted resources and may retransmit preempted portions of the first channel.

Abstract: Different sets of downlink control information (DCI) fields may be configured for DCI that includes an indication to trigger bandwidth part switching at a user equipment (UE). For example, a UE may receive DCI that triggers the UE to switch operation from a first bandwidth part to a second bandwidth part. The UE may also identify a set of transformable DCI fields and a set of non-transformable DCI fields within the DCI. The UE may then determine updated content of the DCI for application to the second bandwidth part based on whether DCI fields are included in the set of transformable or the set of non-transformable fields. In some cases, the UE may identify a null assignment in the received DCI and may switch its operation from the first bandwidth part to the second bandwidth part based on the null assignment.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first wireless communication device may iterate a value of a channel access counter (CAC) to a trigger value based at least in part on configuring the value of the CAC. In some aspects, the first wireless communication device may utilize a channel access mechanism to select a set of time-frequency resources for a transmission of a packet based at least in part on iterating the value of the CAC to the trigger value. In some aspects, the first wireless communication device may transmit the packet to a second wireless communication device via the set of time-frequency resources based at least in part on utilizing the channel access mechanism to select the set of time-frequency resources for the transmission. Numerous other aspects are provided.
