Abstract: There is provided co-channel interference mitigation by power adjustments that take into account sensitivity improvement provided by the sky communications. In connection with a communications network configured for ground communications and sky communications one radio device performs transmission power control of another radio device. If at the controlling radio device, a radio link is determined to be sky communications, at least one power adjustment for controlling the transmission power of the other radio device is determined in accordance with one or more power control parameters for sky communications. The transmission power of the second radio device is controlled by the first radio device, on the basis of the determined at least one power adjustment. In this way co-channel interference mitigation is supported by power adjustments that take into account sensitivity improvement provided by the sky communications.

Abstract: A determination is made, for a base station that transmits on an operating frequency, whether a radiation pattern of each of one or more neighboring frequencies is correlated with a radiation pattern of the operating frequency. In response to a determination that the radiation pattern of each of the one or more neighboring frequencies is correlated with that of the operating frequency, a computation is made of a total radiated power estimate of each of the one or more neighboring frequencies by performing a beam-based directions procedure for the base station. The total radiated power estimates of each of the one or more neighboring frequencies are output.

Abstract: Various schemes pertaining to encoding and transmit power control for downsized trigger-based (TB) physical-layer protocol data unit (PPDU) transmissions in next-generation WLAN systems are described. A station (STA) receives a trigger frame indicating an allocated resource unit (RU) of a first size. The STA performs channel sensing responsive to receiving the trigger frame. In response to detecting at least one subchannel being busy from the channel sensing, the STA performs a downsized trigger-based (TB) transmission with a downsized RU or multi-RU (MRU) of a second size smaller than the first size by utilizing downsized RU or MRU allocation information while maintaining a value of each of one or more parameters unchanged in an encoding process to perform the downsized TB transmission.

Abstract: A user equipment (UE), such as a mobile phone, may support multiple power classes. Power classes can define maximum output power levels for uplink transmissions. A base station of a radio access network (RAN) can, based on metrics reported by the UE, dynamically instruct the UE to switch to using a different power class. For example, the base station may instruct the UE to switch from using a first power class with a higher maximum output power to using a second power class with a lower maximum output power, in order to preserve battery life of the UE in situations in which the second power class provides sufficient output power for uplink transmissions to reach the base station.

The UE may then apply the common gain state to a first receiver chain within the UE for the first RAT and to a second receiver chain within the UE for the second RAT, where the first receiver chain and the second receiver chain share at least one shared low noise amplifier (LNA).

A second estimate of the radio signal at the second sensing device is determined from the second information and the second inverse. Energy emitted from the candidate location is measured based on the first estimate and the second estimate.
