Adaptive gain control for sidelink communications
Methods, systems, and devices for wireless communications are described. A first user equipment (UE) may receive one or more transmissions from one or more UEs in a first slot, including a first transmission from a second UE. The first UE may receive the first transmission using a receiver configured with a first gain and may decode the first transmission. The UE may determine a correspondence (e.g., a temporal correlation) between the first slot and a second slot and may configure the receiver with a second gain at the beginning of the second slot based on the correspondence. The UE may determine that a total received signal power in the second slot is associated with the total received signal power in the first slot. The UE may decode one or more transmissions in the second slot based on the receiver having the second gain at the beginning of the slot.

Low power, low latency, high duty cycle scan for Bluetooth Low Energy
A system, method and apparatus for simultaneously minimizing power and latency in a scan for advertisement packets from one or more peripheral devices in a Bluetooth Low Energy (BLE) frequency band having a number of advertisement channels. A receiver front end receives BLE signals, and a local oscillator (LO) generator has an output frequency that is sequentially tuned to a frequency of each of the advertisement channels. An energy detector monitors signal energy on each of the advertisement channels in sequence, and when the signal energy exceeds a threshold, fixes the output frequency of the LO generator to that advertisement channel. An automatic gain controller controls a gain of the signal on the one of the plurality of advertisement channels to generate a controlled gain signal, and a correlator correlates the controlled gain signal with an advertisement packet on the one of the advertisement channels.
