Abstract: Control information may be identified and provided to a user equipment (UE) that is formatted into a codeword that is transmitted in a first symbol of a downlink transmission to the UE. The control information may include an allocation of downlink or uplink resources for the UE and data processing parameters. The control information may be partitioned into first control information transmitted in a first codeword and second control information that may be formatted into a second codeword. The second control information may be determined based at least in part on the data acknowledgment from the UE. Such partitioned control information may allow a base station to perform some processing related to transmissions for a transmission time interval (TTI) prior to the start of the TTI, and allow the base station to perform some processing for the TTI after the start of the TTI.

Abstract: Some aspects of the disclosure provide for wireless communication systems in which scheduling information is transmitted to a scheduled entity to schedule transmission of uplink feedback control information by the scheduled entity. The feedback control information may be transmitted in short uplink control bursts or long uplink bursts. Selection between short uplink control bursts and long uplink bursts may be based on power headroom at the scheduled entity, interference in the short uplink control burst or the long uplink burst, loading of the short uplink control burst or the long uplink burst or processing capability of the scheduled entity.

Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE) may be configured with a transmission stream processor used to maintain a lower peak-to-average power ratio (PAPR) for uplink transmissions. In some cases, a UE may map modulated symbols of different signals (or waveforms) to interleaved subsets of frequency resources, and this form of frequency division multiplexing (FDM) may increase the PAPR of an uplink transmission. To reduce the PAPR of uplink transmissions, a transmission stream processor at the UE may support techniques for phase ramping modulated symbols in the time domain prior to mapping the symbols to the frequency resources. These techniques may help to ensure that the signals to be included in an uplink transmission are aligned in such a way that the PAPR of the uplink transmission is reduced.

Abstract: A method, an apparatus, and a computer program product for wireless communication are provided. The apparatus may receive an uplink control configuration indication in a downlink control portion of a first slot. The first slot may include the downlink control portion, a second portion, and an uplink short burst portion. The second portion may be located between the downlink control portion and the uplink short burst portion. The apparatus may configure a physical uplink control channel (PUCCH), on at least one of the second portion or the uplink short burst portion of the first slot, for transmission of first uplink control information (UCI) based at least in part on the uplink control configuration indication. The first UCI may correspond to second UCI to be transmitted in the first slot or a second slot. The apparatus may transmit the first UCI on the configured UCI.

Abstract: Aspects of the disclosure relate to inter-link interference cancellation for reducing or mitigating interference from signals in different directions (e.g., uplink and downlink directions). A wireless communication device (i.e., a victim device subject to inter-link interference) may determine a time offset or lead time of an interfering signal from an offending device. Based on the determined time offset, the victim device may perform interference cancellation or suppression to reduce or mitigate the interference of the interfering signal. Other aspects, embodiments, and features are also claimed and described.

Abstract: Wireless communication devices are adapted to facilitate multiple synchronization channels within a single carrier. In some examples, an apparatus for wireless communication may transmit a first synchronization channel at a first frequency in a carrier bandwidth, and at least one additional synchronization channel at a different respective frequency in the carrier bandwidth. In some examples, an apparatus for wireless communication may scan a carrier bandwidth for one of a plurality of synchronization channels conveyed at different respective frequencies in the carrier bandwidth, and discover a synchronization channel from among the plurality of synchronization channels. The apparatus may further receive information conveyed over the discovered synchronization channel and utilize the information to access the carrier. Other aspects, embodiments, and features are also included.
