Abstract: Techniques are described for wireless communication. A first method includes measuring, by a first device, a condition of a wireless channel; and generating at least one channel side information feedback message based on the measured condition of the wireless channel. The at least one channel side information feedback message provides information on a relationship of a set of parameters, including a data rate parameter, an error probability parameter, and at least one of a deadline parameter or a transmission link parameter. A second method includes measuring, by a first device, interference on a wireless channel; identifying an interfering device for the wireless channel based on the measurement; and generating a channel side information feedback message based on the measured interference on the wireless channel. The channel side information feedback message indicates the interfering device for the wireless channel and a correlation of interference from the interfering device with time or frequency.

Abstract: Techniques are described for wireless communication. A method for wireless communication at a user equipment (UE) includes identifying a transmission timing of a control reference signal transmitted over a radio frequency spectrum band during an OFF duration of the UE with respect to the radio frequency spectrum band, in which the identified transmission timing is relative to a transition from the OFF duration to an ON duration of the UE with respect to the radio frequency spectrum band; receiving the control reference signal at the identified transmission timing; and performing a warm-up procedure, before the ON duration, based at least in part on the identified transmission timing of the control reference signal. A method for wireless communication at a wireless network includes indicating, to the UE, the transmission timing of the control reference signal; and transmitting the control reference signal at the indicated transmission timing. The OFF duration and the ON duration are coordinated with a wireless network.

Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE) may be communicating with a base station via beamformed transmissions on an active beam. The UE may receive from the base station refined reference signals (RRSs) that include an active beam RRS corresponding to the active beam. The UE may identify that the active beam RRS corresponds to the active beam and perform a beam state measurement on the active beam RRS. The UE may refine the active beam based at least in part on the beam state information of the active beam RRS.

Abstract: Systems, methods, apparatuses, and computer-readable storage media for managing power consumption of a mobile device are disclosed. The systems, method, apparatus, and computer-readable storage medium may cause the base station to identify an energy metric associated with a mobile device, and to configure the transmission between the base station and the mobile device based at least in part on the energy metric. The configuration of the transmission may reduce the power consumption of the mobile device for processing the transmission.

Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE) may be communicating on a radio frequency spectrum band of a first radio access technology (RAT) using a set of antennas. The UE may reconfigure at least one antenna of the set of antennas to perform a first scan on the radio frequency spectrum band of a second RAT. The UE may determine, based on the first scan, whether to reconfigure a remaining portion of the antennas of the set of antennas to perform a second scan on the radio frequency spectrum band of the second RAT.

Abstract: In wireless communication networks using carrier aggregation, a user equipment (UE) may monitor a downlink radio link quality of secondary cells for an event indicating failure of the communication link with the secondary cell. When a failure event is detected, the UE declares a failure state on the secondary cell. In response to the failure state, the UE may adjust operations related to the secondary component carrier in order to save power and resources.

Abstract: The disclosure relates in some aspects to techniques for improved channel estimation. For example, a device can specify a pilot structure where pilot density differs over time. As another example, a device can indicate that a pilot from a prior transmission time interval (TTI) can be used for channel estimation. As another example, a device can employ frequency domain physical resource block (PRB) bundling with the bundling information signaling. As yet another example, a device can use an adjustable traffic-to-pilot ratio (TPR) for throughput optimization. Other aspects, embodiments, and features are also discussed and claimed.

Abstract: Methods, systems, and devices are described for wireless communication at a UE. A base station may select a hybrid pilot configuration including a relatively sparse periodic pilot and a dense pilot embedded in one or more symbols of a low latency burst. A user equipment (UE) may generate a long term statistical average channel estimate based on the periodic pilot and an instantaneous channel estimate (e.g., for demodulation) based on the dense pilot embedded in the low latency burst. The UE may refine the instantaneous channel estimate by converting a control channel embedded with the burst. In some instances, the base station may embed the dense pilots in the first symbol of a burst and transmit subsequent low latency symbols with a reduced density pilot (or without pilot tones).

Abstract: Aspects of the present disclosure provide for the pairing of an inter-band carrier with a time division duplex (TDD) carrier. If the paired band is a frequency division duplex (FDD) band, then base stations and mobile devices may transmit and receive additional thin control channels on FDD carriers to enable full duplex operations. If the paired band is a TDD band, then a conjugate or inverse carrier may be used such that full duplex, or a close approximation thereto, is achieved. With the introduction of a paired channel and fast control channels, rapid uplink/downlink switching may be achieved for TDD carriers efficiently and effectively. Other aspects, embodiments, and features are also claimed and described.
