An access point may communicate with a wireless device. Different network devices of the access point may use two different power levels (e.g., lower and higher power levels) for communication. A spectrum in a frequency band may be split into multiple sub-spectrums (e.g., channels) that may operate at different power levels. For example, a first sub-spectrum (e.g., channel) may be used for a lower power level and/or a second sub-spectrum (e.g., channel) may be used for a higher power level. The wireless device may determine which power level to use to connect to the access point.

Methods are described for a wireless device to select a cell for registration. Information, shared with the wireless device, may provide details the wireless device may use to select a cell for registration. The information may provide the wireless device with details on which access technologies are available or unavailable, which are restricted or allowed, and/or which frequencies are available and/or their priority of use. Using the provided information, the wireless device may determine possible cells for selection, and based on measurements of the possible cells, the wireless device may select a cell for registration.

Systems, apparatuses, and methods are described for enhancing picture reconstruction in video coding. Bitstream information, such as original bit depth and range indicators, may be used to adjust reconstruction parameters. Compact representations of range differences may be signaled to enable efficient decoding. By adapting clipping ranges for reconstructed samples, the system may improve visual fidelity and reduce artifacts, even when internal processing operates at a different bit depth than the source. These techniques may support flexible configurations and maintain compression efficiency across diverse video formats.

One or more resources may be determined for wireless communications. A wireless device may apply an indication associated with a resource to one or more other resources. One or more conditions and/or parameters may be used to determine whether to use the indication for the one or more other resources.

Methods, systems, and apparatuses are provided for selecting communication channels based on frequency separation requests for a first frequency band and a second frequency band. The system may receive one or more frequency separation requests and determine a first portion of a plurality of devices associated with one or more higher priority level device types and a second portion of the plurality of devices associated with one or more lower priority level device types. The system may determine a maximum frequency separation request associated with at least one of the first portion of the plurality of devices associated with the one or more higher priority level devices. The system may select one or more of a second communication channel of the first frequency band and a second communication channel of the second frequency band based on the maximum frequency separation request associated with the higher priority level devices.

Systems, apparatuses, and methods are described for steering a user device to connect to one network or another network. A network identified as a service set identifier (SSID) broadcast by a wireless transceiver may be directed away from or towards a user device using adjusted transmit parameters associated with the SSID. A network identified as an SSID broadcast by a wireless transceiver may be directed towards a user device, even if the user device is connected to another network identified as another SSID that is still available.

Multiple access points may communicate with multiple wireless devices, such as stations. Channel information between an access point and a station may indicate an ability of the access point to participate in a coordinated beamforming procedure with one or more other access points. A coordinated beamforming transmission by access points may be initiated based on a reception status associated with the channel information.

Systems, apparatuses, and methods are described for wireless communications. A base station may send configuration information for a beam failure recovery (BFR) procedure. A wireless device may determine, based on the configuration information, one or more transmission beam parameters for the BFR procedure. The wireless device may indicate, via an uplink control channel, one or more candidate beams of the base station.

A wireless device may communicate with a base station in a terrestrial or non-terrestrial network. One or more system information block messages may indicate multiple random access resource sets of a synchronization signal block. Each resource may correspond to a different type of random access procedure, such as a 2-step or 4-step procedure. A transmit power pattern of the synchronization signal block may indicate a random access resource set to be used.

Contextual information, for coding prediction modes, may be determined based on a ratio between a quantity of some neighboring nodes and a total quantity of neighboring nodes. A coder, based on the contextual information, may code the prediction modes for coding attribute information of current nodes.

Systems, apparatus, and methods are described for inferring region adaptive hierarchical transform (RAHT) coefficients based on a quantity of coefficients related to a quantity of child nodes of a RAHT tree. Based on the quantity of coefficients, the indication of a prediction mode may be inferred from previously coded (encoded or decoded) neighboring RAHT nodes, or, alternatively, determined from a set of possible prediction modes or from a bitstream. The indication may be inferred from the set of possible prediction modes, for example, if the quantity of child nodes is below a threshold. The indication may be determined from the bitstream, for example, if the quantity of child nodes is above the threshold.

Range information may be used for coding. An indicator associated with range information may be provided. Based on the indicator, the range information may be reused or adjusted by a computing device.
