Abstract: An energy transmitting device (e.g., access point) can transmit an energy signal to a wireless device. The wireless device can obtain energy from the energy signal. The energy signal may be transmitted via an unused frequency sub-range of a frequency range associated with a communication signal. In one embodiment, the energy signal may occupy a frequency sub-range in unused frequencies of an orthogonal frequency division multiplexed (OFDM) signal transmission. The energy signal may be transmitted in a manner that coexists without interfering with traditional communication signals. Various control/configuration settings may be used to enable or disable the energy signal, for example, based on capability of a wireless device to harvest energy from the energy signal or in accordance with a schedule.

Abstract: Methods, systems, and devices for wireless communications are described that asynchronous carrier aggregation, including between high frequency band and lower frequency band transmissions. A user equipment (UE) may be configured to monitor transmissions in a first frequency band and a second frequency band. The UE may measure a timing difference between transmissions in the first frequency band and one or more of the transmissions in the second frequency band, and transmit an indication of the timing difference to a base station. The base station may use the timing difference to determine whether the UE is to use asynchronous carrier aggregation. If the base station determines that the UE is to use asynchronous carrier aggregation, the base station may configure the UE to observe at least a minimum amount of delay when conducting uplink signaling via one of the frequency bands.

Abstract: Methods, systems, and devices for wireless communication are described. A base station may configure a system bandwidth of shared spectrum partitioned into a plurality of bandwidth parts based on interference associated with each of the plurality of bandwidth parts. The base station may then transmit the configuration of the system bandwidth to a plurality of devices. A UE may receive, from a base station, a configuration of a system bandwidth of shared spectrum. The system bandwidth may be partitioned into a plurality of bandwidth parts based on interference associated with each of the plurality of bandwidth parts. The UE may then communicate with the base station on at least one of the bandwidth parts.

Abstract: Methods, systems, and devices for wireless communication are described. Some wireless communications systems may support multi-band operation. Different frequency bands may experience different communication characteristics (e.g., frequency-dependent fading), which may result in undesirable interference patterns and/or coverage gaps. The described techniques provide for channel access methods for multi-band operation. The channel access methods may allow for improved throughput for a wireless communications system. Additionally or alternatively, the described techniques may improve energy efficiency for communicating devices, reduce signaling overhead, or otherwise benefit a wireless communications system. Generally, the described techniques provide for efficient anchoring of high-band communications to low-band transmissions.

Abstract: Methods, systems, and devices for wireless communication are described. A device using a first radio access technology (RAT) to communicate over an unlicensed radio frequency spectrum band may identify a communication pattern for a transmission using a second RAT over the unlicensed radio frequency spectrum band. The identification may be based at least in part on signaling received by the device. The device may determine, based at least in part on the communication pattern, a time period for attempting to transmit the unlicensed radio frequency spectrum band using the first RAT.

Abstract: Aspects of the present disclosure may compensate for movements of a transmitting device when estimating angular information of wireless signals transmitted by the transmitting device. In some aspects, a receiving device may detect a movement of the transmitting device, and determine the angular information of the wireless signals based at least in part on the movement of the transmitting device. The wireless signals may include a first signal received at a first time and a second signal received at a second time, and the angular information may be determined based on the movement of the transmitting device from the first time to the second time. For example, the receiving device may determine the angular information based on the first signal, and may adjust the angular information based on the second signal if the movement of the transmitting device exceeds a threshold distance.
