Abstract: Described herein are implementations for using a remote control device to control a target device on a network via a remote control proxy device. A remote control device may determine an IoT device capable of functioning as a remote control proxy device. The remote control device may generate a data packet comprising a command for controlling the target device and a network address associated with the target device, and transmit the data packet to the IoT device. If the IoT device determines, using the network address, that it is not the target device, the IoT device may either unicast the data packet to the target device or multicast the data packet to multiple intermediate IoT devices on the network.

Abstract: A system and method are disclosed that may provide an accurate estimate of an AP's available medium share. The AP may perform a plurality medium access contention operations to determine a duration of a transmit opportunity and a queue service interval for each of a plurality of access categories. The AP may also determine a queue service interval for a number of packet queues associated with each of the access categories. The AP may use timing information derived from the medium access contention operations to estimate a portion of the medium share available on a per-access category and/or per-user basis. The timing information may include the transmit opportunity durations and queue service intervals for the access categories, the queue service intervals for the individual packet queues, and/or values indicative of the AP's PHY rate and medium utilization.

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 discovery procedures for multi-band operation. The discovery procedures may allow for improved throughput, improved energy efficiency, reduced signaling overhead, as well as other benefits for a wireless communications system. Generally, the described techniques provide for efficient discovery reference signal (DRS) transmissions over multiple frequency bands. The timing of the DRS transmissions across the different bands may be related or the DRS transmission timing for each band may be determined independently.

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.
