    Abstract: A network may use enhanced sounding reference signal (SRS) transmission techniques to support reference signal transmissions over shared spectrum. For example, a wireless device may receive an uplink grant and an indicator. The uplink grant may include an uplink resource allocation to the wireless device and the indicator may alert the device of a forthcoming reference signal transmission. The wireless device may use the uplink grant and the indicator to determine a reference signal transmission period relative to the resources assigned in the uplink grant. For example, the wireless device may determine that the reference signal transmission period is prior to, during, or subsequent to the uplink transmission period. In some cases, a wireless device may be aperiodically or periodically scheduled for reference signal transmissions.

    Abstract: Methods, systems, and apparatuses for uplink descriptor channels are described. An uplink descriptor channel may be used by a user equipment (UE) for providing indications that uplink transmissions over allocated uplink data resources are sent in a configuration different from a configuration indicated by an uplink grant. In various examples an uplink transmission may be transmitted by a UE, and received by a base station, and the uplink transmission may include the uplink descriptor channel with uplink data. An uplink descriptor channel may include indications that uplink control information is included in the uplink transmission, and/or that the uplink transmission employs a number of transmission intervals, a number of channels, and/or a different MCS than those indicated by the uplink grant. A base station may receive the uplink descriptor channel and adjust various parameters of decoding an uplink transmission and/or allocating radio frequency spectrum resources.

    Abstract: Certain aspects of the present disclosure provide methods, apparatus, and computer-program products for the detection of potentially interfering or interfering user equipment (UE) in the proximity of a detecting entity. The detecting entity may be a base station or a UE. In an aspect, the proposed detecting scheme utilizes semi-static system information from one or more neighboring base stations (BSs), and identifies a neighbor BS's UE that causes interference in the physical uplink control channel (PUCCH). The proposed detecting scheme may also identify corresponding resources that are allocated to an interfering UE by the interfering neighbor base station. In aspects, detecting schemes may not utilize information from one or more neighboring BSs.

    Abstract: Systems and methodologies are described that facilitate simultaneous transmission of control information in a single sub-frame. For instance, simultaneous transmission can maintain single carrier waveforms for a control channel even when a plurality of information types is scheduled in concurrently. Channel quality indicators, scheduling requests and acknowledgement messages can be jointly coded. In addition, reference symbols in a sub-frame can be modulated to indicate values associated with a scheduling request or an acknowledgement message. Moreover, in situations where channel quality indicators, scheduling requests and or acknowledgement messages are simultaneously scheduled, one or more can be dropped. Further, a single carrier constraint can be relaxed to enable simultaneous transmission of information in the sub-frame at different frequencies.

    Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a reader device may transmit a delta message that indicates a frequency difference between a data tone frequency for the reader device and a helper tone frequency. The reader device may transmit a data tone signal at the data tone frequency and a helper tone signal at the helper tone frequency. The helper tone signal may be a waveform that is shared among multiple reader devices. Numerous other aspects are described.

    Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a grant that schedules multiple downlink communications, wherein the grant includes multiple start and length indicator values (SLIVs) that indicate respective time domain resource allocations (TDRAs) for the multiple downlink communications and a feedback timing indicator that indicates timing of uplink feedback communications for the multiple downlink communications. The UE may determine that there is a conflict between a timing of a first uplink feedback communication for a first downlink communication of the multiple downlink communications and a TDRA for a second downlink communication of the multiple downlink communications. The UE may adjust at least one of the TDRA for the second downlink communication or the timing of the first uplink feedback communication. Numerous other aspects are provided.

    Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine an amount of time between uplink allocations that is needed for performing frequency retuning during operation at a subcarrier spacing (SCS). The UE may perform frequency retuning in association with hopping from a first set of frequency resources, associated with transmitting a first uplink transmission, to a second set of frequency resources, associated with transmitting a second uplink transmission, during operation at the SCS, wherein the frequency retuning is performed during a set of consecutive unallocated resources determined based at least in part on the amount of time between uplink allocations that is needed for performing frequency retuning. Numerous other aspects are described.
