Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE) may identify a coding rate threshold associated with transmitting an uplink control information (UCI) message during a time period, determine whether to reduce a size of the UCI message based on the coding rate threshold, and transmit at least a portion of the UCI message on uplink shared resources allocated for the time period. The UE may determine to reduce the size of the UCI message by dropping portions of the UCI message based on a size of uplink control resources, a size of uplink shared resources, additional parameters signaled to the UE, or some combination of these factors.

Abstract: Methods, systems, and apparatuses are described for flexible transmissions on one or more frequency division duplexing resources. In some aspects, a subset of resources originally allocated for transmissions in a frequency division duplex (FDD) mode of operation associated with a first base station is identified for reallocation, and the identified subset of resources is reallocated to transmissions in a time division duplex (TDD) mode of operation, for example, associated with a second base station.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may map channel state information (CSI) to first resource elements that are distributed in frequency, wherein the first resource elements are in a set of resources allocated on an uplink shared channel; map hybrid automatic repeat request (HARQ) feedback to second resource elements that are distributed in frequency, wherein the second resource elements are in the set of resources; wherein the second resource elements are reserved for the HARQ feedback and are different from the first resource elements; and transmit the CSI and the HARQ feedback on the uplink shared channel in accordance with the mappings. Numerous other aspects are provided.

Abstract: The described aspects include methods and apparatus for activating a transmitter to communicate in a wireless network. A small cell can determine to activate the transmitter to serve user equipment (UE) in a wireless network. The small cell can then broadcast a portion of a set of broadcast signals in a radio frame and broadcast a remaining portion of the set of broadcast signals along with the portion of the set of broadcast signals in a subsequent radio frame. By refraining from immediately broadcasting all broadcast signals, the small cell can mitigate interference to other small cells. In addition, a UE can determine whether to generate random access channel (RACH) sequences for proximity determination or uplink timing synchronization based on parameters received in a RACH order. Moreover, a small cell with an active transmitter can decode discovery signals from a device to facilitate handover determination.

Abstract: Aspects of the present disclosure provide techniques for uplink (UL) data channel design. An example method is provided for operations which may be performed by a first apparatus. The example method generally comprises determining a number of pilot symbols to transmit for one or more slots of a first subframe based, at least in part, on a coverage enhancement (CE) level, and transmitting at least one uplink data channel having the determined number of pilot symbols in the one or more slots of the first subframe.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may provide hybrid automatic repeat request (HARQ) feedback for multiple physical channels (e.g., multiple physical downlink shared channels (PDSCH)) scheduled via cross component carrier scheduling. A base station may transmit downlink control information (DCI) messages via physical downlink control channel (PDCCH), to the UE to schedule the multiple PDSCH over multiple component carriers. The UE may monitor for the multiple PDSCH over the multiple component carriers, respectively. The UE may identify resource allocations to use for HARQ feedback transmissions associated with the multiple PDSCH, based on the DCI messages received. The DCI may include a number of control fields that the UE may use to determine resource allocations to use for the HARQ feedback transmissions. The UE may thus improve coverage for wireless communications by supporting HARQ feedback for multiple PDSCH scheduled via cross component carrier.

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.
