Embodiments disclosed herein relate to techniques for measuring and/or detecting a signal-to-interference ratio (SIR) of a received signal at a user equipment (UE). The received signal may include a desired signal, co-channel interference, adjacent channel interference, and an in-band blocker. The UE may filter (e.g., remove) the various interferences and in-band blocker. The UE may determine or measure a power (or Received Signal Strength Indicator (RSSI)) of the desired signal and a power (or RSSI) of the co-channel interference separately because the desired signal and the co-channel interference overlap in frequency. To do so, the UE may determine a total power of the received signal including the desired signal and co-channel interference. The UE may receive the desired signal again while an uplink transmission is deactivated (and thus without the interference). The UE may then calculate the SIR based on the total power and the power of the desired signal.

Ue signal to interference power ratio detection for network scheduling assistance

Aggregated channel bandwidth classes that overlap in frequency are allocated for a fallback group. The fallback group may define an increased or maximum bandwidth of aggregated component carriers as allocated by a network. By enabling the aggregated channel bandwidth classes for a fallback group to overlap in frequency, for an available aggregated channel bandwidth, a first aggregated channel bandwidth class may be implemented using a first number of component carriers, and a second aggregated channel bandwidth class may be implemented using a second number of component carriers different from the first. The different number of component carriers may enable more flexibility to more fully utilize the available aggregated channel bandwidth for communication. The network may then allocate one of these aggregated channel bandwidth classes to user equipment that more fully utilizes the available aggregated channel bandwidth for communication.

Carrier aggregation bandwidth classes with overlapping bandwidth ranges

User equipment that is capable of filtering for an irregular bandwidth of an allocated channel may send an indication of this capability to a network, which may then configure the channel to a next higher standard channel size, enabling the user equipment to filter this larger channel bandwidth to the irregular bandwidth. User equipment that is not capable of filtering for the irregular bandwidth may send an indication that it does not have this capability to the network, which may then configure the channel to a next lower standard channel size, thus avoiding the need for the user equipment to filter a larger channel bandwidth to the irregular bandwidth. In cases where the network detects that a blocking signal is not present that may interfere with the allocated channel, the network may configure the channel to the next higher standard channel size.

Systems and methods for supporting irregular bandwidth channels

User equipment may configure a transmitter or receiver to conform to regulations or standards of a geographical region to communicate with non-terrestrial networks (e.g., satellite networks). In one embodiment, the user equipment may receive an indication of a regulation or standard to which to conform to from a terrestrial communication node, and apply an emission mask to the transmitter based on the regulation or standard. The user equipment may additionally or alternatively configure the receiver to be compliant with a noise level tolerance of a received signal specified by the regulation or standard. In some embodiments, the user equipment may implement a frequency offset between the received signal and an interfering signal associated with the noise level tolerance that is scaled based at least on a channel bandwidth associated with the desired signal. Moreover, the user equipment may scale the noise level tolerance based on the frequency offset.

Methods for conforming non-terrestrial network communication to terrestrial standards and regulations

An electronic device may communicate with a wireless base station using a 5G New Radio communications protocol. The base station may balance control timing and receiver performance for the devices in its cell by scheduling communications based on the communications capabilities of each device. This may ensure that the base station is able to provide communications with satisfactory control timing and receiver performance even if multiple different types of device are within its cell. In addition, the device may perform open loop transmit power control operations and then closed loop power control operations. To minimize complexity of the device, the device may only transmit at a maximum output power level during the open loop operations. If desired, the device may only transmit at the maximum output power level when the device is unable to decode a downlink reference signal transmitted by the base station within a predetermined number of symbols.

Methods and devices for estimating an angle between a transmitter and a receiver for beamforming are provided. A method includes, with an antenna element in a first device, transmitting an omnidirectional pulse and detecting an echo of the pulse reflected from a second device. An angle between the first device and the second device is estimated based at least on a characteristic of the echo. The method includes transmitting the angle to the second device for use in beamforming between the first device and the second device.
