Abrégé

Methods and apparatuses for noise learning-based denoising of noisy input data Y that is equal to the original data X plus the noise N (i.e., Y=X+N). In contrast with a conventional denoising autoencoder (DAE) method that attempts to learn the original data X directly from noisy input data Y, the noise learning-based denoising learns the noise N in the noisy input data Y and then regenerates the original data X by subtracting the learned noise N from the noisy input data Y. Learning the noise N may include inputting the noisy input data Y into an encoder of a neural network, and the learned noise N may be output from a decoder of the neural network. Training the neural network may include inputting noisy training data into an encoder of the neural network and outputting training noise from a decoder of the neural network.

Techniques are provided to enable radio devices to operate using irregular bandwidths that are not defined channel bandwidths by the applicable RAT. A UE designed to limit emissions outside the irregular bandwidth block but within the channel bandwidth can indicate this capability when it accesses the network. When a UE indicates a capability to use irregular bandwidths, the network can schedule the UE in an irregular bandwidth block while blanking the part of the channel bandwidth outside the irregular bandwidth block in order to maximize the use of the irregular bandwidth block. If a UE does not indicate capability for using irregular bandwidth blocks, the network can schedule the UE in a defined bandwidth inside the irregular bandwidth block provided there is a defined channel bandwidth less than the irregular block bandwidth.

Abrégé

A method performed by a node (111) supporting operation on a Constrained Application Protocol (CoAP), but incapable of supporting operation on a Domain Name System (DNS) protocol. The node (111) encodes (402) a DNS query into a first message (601, 701), which has a format supported by the CoAP. The DNS query is mapped to the CoAP format of the first message (601, 701) based on a mapping scheme. The node (111) then initiates sending (403) the first message (601, 701) to another node (112) operating in the communications network (100). The another node (112) supports operation on the CoAP and on the DNS protocol. The node (111) finally receives (404) a second message (620, 706) from the another node (112), which has the format supported by the CoAP. The second message (620, 706) comprises the DNS response to the sent DNS query. The DNS response is mapped to the CoAP format of the second message (620, 706) based on the mapping scheme.

Abrégé

A User configures the option in his/her UE to deliver the SMS via Operator's application client installed on UE. This configuration will be saved in the UDM as an option opted by UE. SMS-GMSC receives the “SMS delivery flag (indicating alternate delivery mechanism is enabled)” from UDM in response to the “Send Routing Infor for SM” message. If the traditional SMS delivery over mobile operator network fails (e.g. no connectivity), then SMS-GMSC will trigger NEF to re-attempt the SMS delivery to UE. (NEF can be an optional network function as Application function is trusted one and hosted in Operator's network). NEF sends the SMS to Application Function (Mobile Network Operator's Serer) which encrypts the SMS payload and delivers the SMS to operator's application client e.g. Mobile Network Operator App installed on UE over the alternative data connectivity (Ex. Wi-Fi Broadband). Therefore, if the User has data connectivity by alternative means (via different channels like Wi-Fi hotspot, Home Wi-Fi broadband, another Operator SIM etc.), it should be possible to deliver an SMS update on Operator's application client installed on UE.

A map processing device obtains images from a camera transported with a mobile device, and detects 2D features in the images. At least some of the 2D features detected in the images are densified to generate a densified set of 2D features. Locations of the densified set of 2D features are determined in 3D space using an image-based localization algorithm. A structure-based map comprising depth information from a depth sensor transported by another mobile device is accessed, wherein the depth information includes a set of data points indicating locations in 3D space corresponding to features in the real-world sensed by the depth sensor. The camera transported with the mobile device is localized to the real-world based on matching the locations of the densified set of 2D features in 3D space to the depth information accessed in the structure-based map.
