Abstract: The described technology is generally directed towards over the air synchronization of network nodes. In general, the techniques disclosed herein can be implemented by a first base station node device and a second base station node device. A wireless backhaul connection between the base station node devices allows the first base station node device to connect to a core network via the second base station node device. The techniques disclosed herein can be implemented as a protocol including communications back and forth between the base station node devices, which enables measurement of communication delays such as propagation delays and processing delays. The base station node devices can then use the measured communication delays to better synchronize clocks used to time radio frequency transmissions.

Abstract: The described technology is generally directed towards multidimensional grid sampling for radio frequency power feedback. A mobile device can sample radio frequency signal power at multiple sample points, and can send sample values to a base station. The multiple sample points can be defined with reference to a grid having a first dimension and a second dimension, such as time and frequency, or delay and Doppler. A variety of techniques are provided to define the multiple sample points.

Abstract: To increase network efficiency, a user equipment (UE) can be appointed as a local manager to coordinate the allocation of resources used by other UEs. For example, the network can promote the UE as a local manager and assign the local manager a resource pool. The local manager can then broadcast synchronization signals to let the other UEs associate themselves with the local manager. After the other UEs are synced with the local manager, the local manager can allocate resources to the other UEs. Based on report data regarding the local managers management procedures, the network can maintain the UE as the local manager or demote the UE from local manager status.

Abstract: The described technology is generally directed towards sharing a radio by multiple subscriber identities at a device. A time division multiplexing pattern at the device radio gives primary radio use to a first subscriber identity, while also providing time windows for radio use to a second subscriber identity. In response to a communication by the second subscriber identity, the time division multiplexing pattern can be changed to give the primary radio use to the second subscriber identity. Also, a radio resource control protocol can designate appropriate states for the different subscriber identities, designating the subscriber identity with primary radio use as connected, while the other subscriber identity is designated as inactive or idle.

Abstract: A method may include a processing system of a channel sounding receiver having a processor detecting a synchronization signal within a time and frequency resource grid of a base station and measuring a channel property at a first location based upon the synchronization signal that is received at the first location. The method may further include the processing system receiving at a second location, from the base station, the synchronization signal, measuring a channel property at the second location based upon the synchronization signal that is received at the second location, and selecting between the first location and the second location for a deployment of a customer premises equipment based upon the channel property at the first location and the channel property at the second location.

Abstract: The disclosed subject matter is directed towards a clear channel assessment procedure based on a common preamble, such as for use with 3GPP and IEEE 802.11 technologies, or any other radio technology, including for use in the 6 GHz band. Detection of the common preamble is based on detecting known sequences in signal part, which can be detected without decoding the preamble's payload (channel) part to determine an ongoing transmission's duration. If an ongoing transmission is detected, subsequent energy detection monitoring is performed to determine when transmission ends, which can use a different energy detection threshold from what is used in the initial clear channel assessment's energy detection. The technology facilitates the usage of different sampling rates by different radio technologies that work concurrently in the same unlicensed band, by correlating a received preamble with a stored preamble that accounts for deterministic distortions arising from the different sampling rates.
